Description

BACKGROUND

Portable toilets (hereinafter portalets) allow users to have the benefit of a toilet without an established waste management system. Portalets are utilized in many environments, including construction sites, outdoor festivals, and remote locations. Some of these environments can be hazardous, such as off shore oil platforms. Hazardous environments can include dangers such as high winds knocking over an unsecured portalet, explosions close to the portalet location, and toxic gases in the area. If a portalet is in hostile environment, the user may be exposed to dangers related to the environment when near the portalet.
Portalets suffer from several design related issues. First, they are difficult to transport. Due to the nature of their contents (water, chemicals, or waste), they need to be transported in an upright orientation. This is typically accomplished by some form of manual transportation (a person actually pushing or pulling the portalet), or using a machine to move the portalet when the portalet was not designed to interface with the machine. Another issue related to the use of portalets is they are typically used in a setting where there is little existing infrastructure for power and safety equipment, meaning that a user may not be able to access those items if needed.
These issues and others have led to the development of the present invention.

FIELD OF THE INVENTION

The present invention relates to an improved portalet 100, and specifically to improvements in the design to increase user safety in a hostile environment and facilitate ease of transport.

SUMMARY

The disclosed invention relates to improvements in a portalet to increase user safety and facilitate ease of transport. The structure of the improved portalet 100 is reinforced with materials to increase the survivability of the improved portalet 100 in the event of a nearby explosion. The improved portalet 100 also has multiple points where machinery can connect to the improved portalet 100 for transport, notably by crane and forklift. Additionally, first aid and safety gear are installed to increase user safety in the event of a hazardous situation near the improved portalet 100.

DETAILED DESCRIPTION

The invention relates to an improved portalet 100 that may be easily transported and has additional features related to safety in a hazardous environment. Specifically, the disclosed invention may be designed with various international standards in mind, such as DNV standards for equipment used in the oil and gas industry. The improved portalet 100 comprises an enclosure 126 containing several items, such as the toilet flush tank 106, the toilet, and the toilet catch basin 108 along with a sink and urinal 110. The improved portalet 100 is reinforced to withstand the force generated by an explosion on an offshore oil platform. Such mechanisms of reinforcement are known to those skilled in the art, such as the use of high strength materials with the appropriate level of strength and elasticity to build the structure and outer surface of the improved portalet 100. In an exemplary embodiment, the improved portalet 100 may be capable or resisting a six pound per square inches of force.
In an exemplary embodiment, the weight distribution of the improved portalet 100 is designed to favor the base. While other portlets are designed to be oriented upright, they are not designed with sufficient weight in the base to prevent them from being knocked over due to winds above a certain minimal level without extra support. In an exemplary embodiment, the improved portalet 100 will remain upright during sustained forces from both storms and explosions due to the weight of the improved portalet 100 concentrated in the base.
The interior in the improved portalet 100 may be in any configuration of a portalet currently in use. In the exemplary embodiment, there is a flush toilet, a urinal 110, and a sink. The toilet comprises a toilet flush tank 106 to hold the water used by the toilet, a toilet catch basin 108 to collect the used “grey” water from the toilet, and a commode resting on top of the toilet catch basin 108 for the user to sit on. The toilet and urinal 110 share the toilet flush tank 106 and a toilet catch basin 108. In operations, a user uses the toilet or urinal 110 and flushes. Water discharges from the toilet flush tank 106 and removes the contents of the commode or urinal 110 along with the water. The solid waste and grey water is collected in the toilet catch basin 108. As the solids collect in the toilet catch basin 108, they may be withdrawn through a clean out hatch 306. If fluids need to be drained from the toilet catch basin 108, a drain port 308 may be opened to drain the grey water and other fluids. The toilet flush tank 106 may be refilled as needed.
When the toilet catch basin 108 begins to fill, the level of waste is indicated by a waste level indicator in the interior of the enclosure 126. The waste level indicator operations can be based on any mechanism known to those skilled in the art. In an exemplary embodiment, a sensor can determine the level of waste in the toilet catch basin 108 and illuminate the appropriate indicator. In an alternative embodiment, there can be a waste level indicator in the exterior of the enclosure 126.
In an alternative embodiment, the grey water in the toilet catch basin 108 is treated for use in the system again. A toilet pump may send the grey water back into the toilet flush tank 106 when the next flush occurs, or it may immediately pump the grey water to the toilet flush tank 106, allowing gravity to power the toilet flush. The grey water may be recycled for multiple toilet flushes. Additionally, a chemical additive may be incorporated into the grey water system to reduce the growth of bacteria.
A sink may also be installed in the improved portalet 100 according to an exemplary embodiment. The sink may draw water from the toilet flush tank 106 and discharge the water to the toilet catch basin 108. In an alternative exemplary embodiment, the sink has a sink water tank independent of the toilet flush tank 106. When the sink is operated, the sink water leaves the sink and goes into a sink catch basin. From the sink catch basin, the sink water may be recycled by any means known to those skilled in the art for later use in the sink, such as being filtered and pumped back into the sink water tank.
In an additional exemplary embodiment, the improved portalet 100 may be connected to a water supply that provides and disposes of water as needed. In an alternative exemplary embodiment, the toilet may be a chemical toilet. In further alternative exemplary embodiments, the may be no urinal 110 and just a toilet. In a further alternative exemplary embodiment, the sink may dispense a waterless sanitizer in place of water. In further alternative exemplary embodiment, the may be no sink.
The exemplary embodiment of the invention provides power for improved portalet 100 operations. In an exemplary embodiment, the improved portalet 100 is a self-contained system, using a solar panel 112 to collect energy to be used in the improved portalet 100 operations. In an alternative embodiment, a wind turbine 114 may be incorporated to provide power. Power generated by an element of the improved portalet 100 may be stored in any way known to those skilled in the art, including batteries. The power may be used for any function needed, including lights and pump operations. In an alternative exemplary embodiment, the improved portalet 100 couples to an external power source, such as the generator powering an offshore oil platform.
Mechanisms may be incorporated into the improved portalet 100 to prevent accidental electrocution while the equipment is in service. Access to any electrical systems in the exemplary embodiment may only occur via a safety mechanism, such as a “lock out/tag out” system to make sure that only the user who shut down an element to perform maintenance is the only one who can release the element to return to service. Further, all electrical system and wiring may be configured to comply with DNV standards in an exemplary embodiment.
The improved portalet 100 is designed to be used in a hazardous environment. Multiple items and features are incorporated into an exemplary embodiment for user safety. In the interior of the enclosure 126 is a fire extinguisher. An alternative embodiment may locate the fire extinguisher on the exterior of the enclosure 126. Inside the enclosure 126 are various items, such as a defibrillator for use with cardiac emergencies. Also installed within the enclosure 126 in an exemplary embodiment is a limited air supply in the event that toxic gases are in the area. In a further exemplary embodiment, a basic communication device is available to request help.
In an exemplary embodiment, one side of the enclosure 126 may include an instruction panel 122 with safety information including, but not limited to, CPR instructions. Adjacent to the instruction panel 122 is a first aid kit 120 that contains typical first aid supplies. Co-located to the first aid kit 120 is an eye wash station 124 to help rinse foreign matter out of a user's eyes if needed. The eye wash station 124 may use a water supply independent of any others used by the improved portalet 100, or may draw on the water in toilet flush tank 106. Additionally, the exemplary embodiments may contain receptacles to hold safety equipment, such as life vests, emergency blankets, ear plugs, and safety glasses.
In an exemplary embodiment, there are structural elements that assist in the transportation of the improved portalet 100. The disclosed structures are independently operable of each other or may be used in concert. In the base of the improved portalet 100 are channels 104 that are dimensioned to accommodate the forks of a forklift. The forklift may drive up to the improved portalet 100, inset the projections into the appropriate channel 104, lift the improved portalet 100 off of the surface, and drive the improved portalet 100 directly to where it is needed. The improved portalet 100 may then be lowered and secured in any way known to those skilled in the art.
An alternate mechanism for transportation comes from crane couplers 102 atop the improved portalet 100. Crane couplers 102 connect the improved portalet 100 to a crane or the crane hoist line to lift and place the improved portalet 100 directly where needed. In an exemplary embodiment, the crane couplers 102 are integrated into the corner supports of the improved portalet 100. In an alternative exemplary embodiment, the crane couplers 102 may be located anywhere on the improved portalet 100 that allows the crane to attach to the improved portalet 100.
