In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.
[0026] like Figures 1-2 As shown, this utility model provides a low-energy green intelligent public toilet system, including a rainwater collection mechanism, a squat toilet mechanism, a water pump 9, a single-compartment septic tank 16, a double-compartment septic tank 17, and an exhaust riser 18.
[0027] The rainwater harvesting system includes a water storage tank 6 and a rainwater harvesting plate 1. The water storage tank 6 is installed on the ground. The rainwater harvesting plate 1 is installed on top of the water storage tank 6, and the rainwater harvesting plate 1 causes falling rainwater to tend to flow towards the water storage tank 6.
[0028] There are multiple squat toilet units, spaced apart. Each squat toilet unit includes a squat toilet 14 and a water tank 13. The squat toilet 14 is installed on the ground. The water tank 13 is installed on the wall of the toilet, and the outlet of the water tank 13 is connected to the inlet of the squat toilet 14.
[0029] The inlet of the water pump 9 is connected to the water storage tank 6 through the pumping pipe 11, and the outlet of the water pump 9 is connected to the inlet of the water tank 13 through the delivery pipe 12.
[0030] The single-compartment septic tank 16 is installed underground, and the inlet of the single-compartment septic tank 16 is connected to the outlet of the squat toilet 14 through a sewage horizontal pipe 15.
[0031] The double-chamber septic tank 17 is installed underground. The inlet of the double-chamber septic tank 17 is connected to the outlet of the single-chamber septic tank 16, and the outlet of the double-chamber septic tank 17 extends underground. Both the double-chamber septic tank 17 and the single-chamber septic tank 16 are existing technologies, and their specific structures will not be described in detail here.
[0032] The exhaust riser 18 is connected to both the single-compartment septic tank 16 and the double-compartment septic tank 17. Specifically, the exhaust riser 18 is connected to the single-compartment septic tank 16; the double-compartment septic tank 17 is connected to the exhaust riser 18 via the exhaust bend 20.
[0033] The specific working process of this system is as follows: Rainwater collection plate 1 is responsible for guiding and collecting rainwater, and all collected rainwater is collected in the storage tank 6 for later use. Water pump 9 draws water from the storage tank 6 through the pumping pipe 11, pressurizes it, and sends it through the delivery pipe 12 to each water tank 13 as flushing water for the squat toilet 14. When the toilet user starts the flushing program of the water tank 13, the toilet user's excrement and the water in the water tank 13 will be flushed together through the sewage horizontal pipe 15 into the single-compartment septic tank 16.
[0034] The single-chamber septic tank 16 performs preliminary treatment of sewage. When the single-chamber septic tank 16 overflows, the sewage automatically flows by gravity through the connecting pipe 21 to the double-chamber septic tank 17 for further treatment. Harmful gases in the single-chamber septic tank 16 and the double-chamber septic tank 17 are finally discharged to the outside through the exhaust riser 18. After the sewage has been further treated in the double-chamber septic tank 17, it is distributed through the distribution pipe to multiple buried perforated infiltration pipes 24, and evenly infiltrates into the underground soil layer. Under the conditions of low population density and low sewage load in remote areas, the effluent after two-stage septic tank pretreatment and deep purification by the soil infiltration system is relatively harmless wastewater, which will not pollute the local ecological environment, and the small amount of nutrients it contains can be absorbed and utilized by the surrounding vegetation.
[0035] It is worth noting that during the dry season or peak water consumption season, water can be supplied to the reservoir 6 by town water trucks.
[0036] After flushing the squat toilet 14, urine and feces sequentially enter the single-chamber septic tank 16 and the double-chamber septic tank 17 for harmless sedimentation treatment. Finally, they are discharged harmlessly on-site through buried infiltration, eliminating the tedious daily collection of urine and feces. This system does not require consideration of excrement volume, is odorless, or requires the collection and transportation of excrement, thus reducing toilet management and operation work and improving toilet hygiene, making it suitable for remote areas.
[0037] In one embodiment, it also includes a solar panel 2, a wind turbine 25, and a control cabinet 7.
[0038] The solar panel 2 is fixedly mounted on the rainwater collection plate 1. The control cabinet 7 is electrically connected to the solar panel 2, the wind turbine 25, and the water pump 9.
[0039] This system is a low-energy, green system powered entirely by solar panels 2 and wind turbines 25, providing clean energy. All electrical energy and transformer power are stored in control cabinet 7, which supplies power to this system.
[0040] In one embodiment, a rainwater sedimentation tank 3 is formed at the bottom of the rainwater collection plate 1, and a water outlet 4 is formed at the bottom of the rainwater sedimentation tank 3. The water outlet 4 is connected to the water storage tank 6, and a filter plate is installed at the water outlet 4.
[0041] After the rainwater collection plate 1 collects rainwater, the rainwater flows into the rainwater sedimentation tank 3 to settle the sediment, and then flows into the water storage tank 6 through the middle filter plate for later use, in order to reduce the turbidity of the rainwater.
[0042] In one embodiment, the system also includes a distribution pipe and multiple perforated infiltration pipes 24. The distribution pipe is connected to the outlet of the double-compartment septic tank 17, and the multiple perforated infiltration pipes 24 are buried underground and are all connected to the distribution pipe.
[0043] After being deeply treated by the double-compartment septic tank 17, the sewage is finally distributed by the distribution pipe to multiple buried perforated infiltration pipes 24 and naturally seeps into the ground, resulting in a wider infiltration range and a more uniform infiltration effect.
[0044] In one embodiment, a water level probe 10 is also included, which is fixedly installed on the inner wall of the water storage tank 6 and electrically connected to the control cabinet 7.
[0045] The water level probe 10 is used to detect the water level in the water storage tank 6. When the water level is low to the warning level, it automatically sends a water truck delivery request through the control cabinet 7, which improves the intelligence of the system.
[0046] In one embodiment, a vent cap 19 is installed at the outer port of the exhaust vertical pipe 18 to achieve ventilation and expel hot air, moisture and foul air from the toilet.
[0047] In one embodiment, both the single-compartment septic tank 16 and the double-compartment septic tank 17 have an inspection port 26 at the top, and an inspection cover is installed on the inspection port 26. The management unit needs to periodically clean the sludge through the inspection port 26.
[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
