Small public toilet

Abstract

The invention provides a small public toilet and supporting facilities. The small public toilet is small in occupied area, does not need to excavate a large amount of earth and stones during construction, and is particularly suitable for being constructed in small parks, streets and villages. The construction cost of a small public toilet is far lower than that of a squatting position in an equal large public toilet, a lot of public pool areas are saved in construction, expenditure is saved, and urgent needs of people can be met. The small-sized public toilet can replace a large-sized public toilet in density, or can make up for the disadvantage of having a street and not having a toilet. According to the flow density of people, the small public toilet is especially placed in a miniature park which is built at present, which is a good benefit. One small-sized public toilet is arranged at a proper distance in a street, two small-sized public toilets can be arranged as required, and even a plurality of small-sized public toilets can be intensively arranged together in places where people are very concentrated to form a large-sized public toilet for use. A small public toilet body is composed of a concrete foundation (1), a base (2), wall plates (3), a roof (4), a solar panel (5), a manure storage pool (24) and the like.

Description

Technical Field

[0001] This technology belongs to the field of environmental sanitation. Background Technology

[0002] In the construction of public toilets in cities, there are toilets in densely populated areas, but in some streets, there is only one toilet every few miles. Developing and building small-scale public toilets can make up for and solve the above situation and shortcomings. Summary of the Invention

[0003] This invention provides a small public toilet and its supporting facilities. This small public toilet occupies little space and requires minimal earthwork during construction, making it particularly suitable for small parks, streets, and some medium and small towns in cities. The construction cost of a small public toilet is far lower than the average cost of a single squat toilet in a large public toilet. It saves considerable shared space during construction, reducing expenses while addressing urgent needs. Small public toilets can replace large public toilets in terms of density, or compensate for the lack of toilets on streets. The placement of a small public toilet is particularly beneficial in newly built mini-parks, depending on population density and mobility. One can be installed at appropriate intervals along streets, and two can be installed if needed. In areas with high population density, multiple small public toilets can even be combined to form a large public toilet. The main body of the small public toilet consists of a concrete base, foundation, wall panels, roof, septic tank, and necessary supporting facilities. The concrete base can be precast or cast on-site; the (toilet) base, wall panels, roof, and (with door frame) door are all integrated and made from thick wooden boards; the base, wall panels, roof, and (with door frame) door are joined using mortise and tenon joints (straight tenons), and after assembly, a layer of stainless steel sheet is attached to the wooden board (or a layer of stainless steel sheet is attached to the precast component); the four corners inside and outside the small public toilet are reinforced with metal angle steel; the base is equipped with a stainless steel (squatting) toilet bowl, which is an independent component. The four sides of the toilet bowl extend outward to the bottom corner of the wall panel and can be installed and disassembled independently. Lifting the toilet bowl opens the cover of the (below) septic tank, making it easy to replace the filter screen in the septic tank and pump out the fecal sludge during future maintenance. The cover of the septic tank is fitted onto (fixed) the drain pipe under the toilet bowl, with the lower end of the drain pipe extending directly into the parallel filter screen inside the septic tank. A handrail is installed on the left and right wall panels and inside the door. At the rear of the house, a clean water tank and a wastewater tank are installed, along with a solar panel with energy storage capabilities. The clean water tank is connected to tap water, with an automatic check valve controlling the water inlet and supplying water to the washbasin and toilet. Wastewater from the washbasin flows through a conduit into the wastewater tank. The wastewater tank (for recycling) stores filtered wastewater. The solar panel powers nighttime lighting and the wastewater recycling pump. The lighting is controlled by a light-controlled switch, and the pump is powered by a floating touch-sensitive switch. The septic tank is installed under the concrete base, either separately from the wastewater tank, or separated by a partition at two-thirds of the septic tank, with the remaining two-thirds serving as the septic tank. A parallel filter screen is installed in the middle of the septic tank, with a vertical opening above the partition, and the remaining one-third serving as the wastewater tank.A floating body is installed at the bottom of the sewage tank, connected to a top rod via a soft rope. The top rod is connected to a power cord (on / off). During toilet use, sewage in the septic tank rises, passes through a parallel filter, and then through a vertical filter before flowing into the sewage tank. As the water level in the tank rises, the floating body rises and triggers the top rod, which then activates the power switch, starting the water pump. When the water level drops back to the bottom of the tank, the floating body, driven by the rope, pulls the power switch, stopping the pumping. This cycle repeats, automatically extracting and filtering sewage. The extracted sewage enters a sewage recycling tank above. The recycled sewage pipe is connected to the tap water in the clean water tank for flushing the toilet. Sewage recycling saves toilet water. The septic tank is located under a concrete base, with the walls reinforced with cement or bricks. Wastewater that has undergone sedimentation and secondary filtration can also be discharged directly into the ground through a (vertical) opening, thus eliminating the need for wastewater storage tanks, wastewater recycling tanks, and pumps.

Detailed implementation method: The main body of the small public toilet consists of (1) a concrete base, (2) a base, (3) wall panels, (4) a roof, (5) a solar panel, and necessary supporting facilities. (1) The concrete base can be precast or cast on site; (2) the base, (3) wall panels, (4) roof, and (33) door frame are made of wood planks; (31) the door of (1) the base, (2) wall panels, (3) roof, and (33) door frame is connected by mortise and tenon structure (straight tenon). After the construction, a layer of stainless steel sheet is pasted on the wood plank. The inner and outer corners are reinforced with stainless steel or aluminum alloy corrosion-resistant angle steel; (1) a stainless steel squatting (10) toilet is set on the top of the base. The stainless steel (10) toilet is an independent body. The four sides extend outward to the corner of (3) wall panel. It can be installed independently. After lifting the toilet, the (25) cover of (24) septic tank can be opened, which makes it easy to replace the (24) septic tank in the future. The filter screen and the sludge in the suction tank; (10) the toilet bowl's (23) drain pipe extends downwards beyond (27) the parallel filter screen; (29) a washbasin (faucet) is installed inside the house, and a handrail is installed on the left and right wall panels and behind the door; outside the house, the following are installed: (11) a clean water tank, (17) a sewage tank, (4) a solar panel with a power storage function (5) is installed on the roof; (11) the clean water tank is connected to the tap water and controlled by an automatic stop valve, and the tap water is supplied to the (29) washbasin; (13) the sewage tank stores (recycles) the filtered sewage; (13) the sewage recycling tank is equipped with (15) an overflow outlet, (5) the solar panel supplies electricity for the toilet's nighttime lighting and the (22) water pump for recycling wastewater; (8) the lighting is controlled by a light-controlled switch; (24) a septic tank is installed below the toilet. (24) The septic tank and (17) the sewage tank are made and installed separately, or (such as Figure 7 (24) The middle two-thirds of the septic tank is separated by a partition (38). The middle two-thirds serves as the septic tank. A parallel filter (27) is installed in the middle of the septic tank, and a vertical filter (28) is installed above the partition (38) to filter the sewage in the septic tank (24). The remaining one-third serves as the sewage tank (17). (e.g.) Figure 5(17) A (18) floating body is set at the bottom of the sewage tank. The (18) floating body is connected to the (20) top rod above by (19) soft rope. The (20) top rod is connected to the (18) power wire. When the sewage level in the sewage tank rises, (it drives) the (18) floating body to float up and touch the (20) top rod. The (20) top rod hits the (21) power switch, (connects the power) and starts the (22) water pump to pump water. The pumped sewage enters the (18) sewage (recycling) tank. The recycled sewage is connected in series with the clean water in the (11) clean water tank for flushing the toilet, which can save some toilet water. When the sewage level in the (17) sewage tank drops to the bottom after being pumped out, the (18) floating block disconnects the power switch under the action of (19) soft rope and stops pumping water. This cycle repeats, realizing automatic extraction of (filtered) sewage. Alternatively, the wastewater after sedimentation and filtration can be directly discharged into the ground, thus saving the cost of (17) wastewater recycling tanks and pumps.
