Description

Technical Field

[0001] The invention relates to the technical field of toilet flushing wastewater treatment, and in particular to an environmentally friendly public toilet wastewater and waste gas treatment device. Background Art

[0002] Public toilets, or public toilets, refer to toilets used by urban residents and floating populations, including toilets attached to public buildings (such as stations, hospitals, cinemas, exhibition halls, office buildings, etc.). These toilets can be divided into two categories: water-flushed toilets and dry toilets according to the different flushing methods. Among them, water-flushed toilets are the main form of urban public toilets. Their internal facilities include toilets, flushing equipment and hand-washing equipment. Some toilets also have heating equipment, ventilation equipment and toilets for the disabled.

[0003] The existing Chinese patent with publication number CN109267609B discloses a toilet sewage treatment device suitable for intelligent environmentally friendly mobile toilets, but the patent and the prior art also have the following defects:

[0004] First, the above patent supplies water to the toilet through a rainwater collection pool. When the rainwater collection pool collects rainwater, foreign objects such as leaves and branches outside will fall into the rainwater collection pool. In order to prevent foreign objects from falling into the rainwater collection pool, the above patent sets a shielding plate above the rainwater collection pool. Although the shielding plate can prevent foreign objects from flying into the rainwater collection pool, it cannot prevent foreign objects from flowing into the rainwater collection pool along the collection plate with rainwater;

[0005] Second, each toilet in a public toilet is connected to a drainage pipe. Several drainage pipes in a traditional public toilet are connected to the municipal sewer main. The municipal sewer main is a long pipe that connects all public toilets in an area. Since the amount of wastewater discharged from public toilets is large, it is difficult to lead the wastewater produced by public toilets to the sewage treatment plant in time by relying on a single municipal sewer main. Once the municipal sewer main is blocked, all public toilets in the current area will have sewage upflow.

[0006] Third, the flow of sewage in the municipal sewer main is driven by the drainage of upstream public toilets. In order to ensure the continuous flow of sewage in the sewer main, the upstream water plant needs to regularly discharge a certain amount of water into the sewer main to push the sewage. Although this method can reduce the probability of the sewer main being blocked, it will waste a lot of water resources.

[0007] Therefore, it is necessary to provide an environmentally friendly public toilet wastewater and waste gas treatment device to solve the above problems. Summary of the invention

[0021] Secondly, several drainage pipes of the device are connected to the inclined sewer main pipe. The sewage falling into the sewer main pipe flows to the sewage collection box by gravity. When the sewage water level in the sewage collection box rises to a certain level, the sewage will fall into the liquid collection tank. During this process, the sealing valve will open the drain port on the water storage tank through the transmission of the traction transmission rope. Finally, the rainwater in the water storage tank will rush to the sewer main pipe, thereby promoting the flow of sewage in the sewer main pipe, preventing the sewer main pipe from being blocked by feces, and the water storage tank is stored as rainwater, which can effectively reduce the consumption of municipal water resources;

[0022] Thirdly, the sewage collecting tank of the device is used to store the sewage produced by the public toilets, and each public toilet is equipped with a sewage collecting tank. After using the sewage collecting tank, the sewage discharged from the public toilets will no longer be discharged into the municipal sewer main, thereby reducing the load of the municipal sewer main, and even if the sewer main is blocked, it will only affect the drainage of the current public toilet and will not affect the drainage of adjacent public toilets.

[0047] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] refer to Figures 1 to 23An environmentally friendly public toilet wastewater and waste gas treatment device shown in the figure includes a sewer main pipe 1 and a plurality of sewer drain pipes 2, the sewer main pipe 1 is in an inclined state, the plurality of sewer drain pipes 2 are equidistantly distributed along the axial direction of the sewer main pipe 1, and each sewer drain pipe 2 is vertically connected to the sewer main pipe 1, a water storage tank 3 is provided above the sewer main pipe 1, a rainwater collecting mechanism 4 is provided above the water storage tank 3, a rainwater inlet 5 is provided at the top of the water storage tank 3, a drain port 6 connected to the starting end of the sewer main pipe 1 is provided at the bottom of the water storage tank 3, and a sealing valve 7 is provided on the drain port 6, and an elastic pressure piece is provided on the sealing valve 7 to keep the sealing valve 7 in a normally closed state, and a sewage collecting box 8 is provided below the sewer main pipe 1, and a vertical partition is provided in the sewage collecting box 8 9. The partition 9 divides the inner cavity of the sewage collecting box 8 into a feces storage chamber 10 and a liquid storage chamber 11. The top of the sewage collecting box 8 is provided with a feces extraction port 12 and a sewage inlet 13 both connected to the feces storage chamber 10. The sewage inlet 13 is connected to the end of the sewer main 1. The feces extraction port 12 is provided with a sealing plug 14. A notch 15 is opened on the top of the partition 9. A liquid collecting mechanism is provided in the liquid storage chamber 11. The liquid collecting mechanism includes a liquid collecting tank 16 and a drainage tank 17. The drainage tank 17 is fixed in the water storage tank 3. The liquid collecting tank 16 slides above the drainage tank 17 in a vertical direction. A drain valve 18 is provided at the bottom of the liquid collecting tank 16. A push pin 19 is provided in the drainage tank 17 to push the drain valve 18 open. A traction transmission rope 20 is provided between the liquid collecting tank 16 and the sealing valve 7.

[0049] The rainwater collecting mechanism 4 discharges the collected rainwater into the water storage tank 3 through the rainwater inlet 5. Since the sealing valve 7 is in a normally closed state, the rainwater entering the water storage tank 3 at this time will not be discharged through the drain port 6. When the sealing valve 7 closes the drain port 6, the liquid collecting tank 16 will be pulled to an ascending state by the traction transmission rope 20. At this time, the gravity of the liquid collecting tank 16 is less than the pressure of the elastic pressure piece, so the liquid collecting tank 16 will remain in an ascending state. The upper end of each sewer pipe 2 leads to a toilet in the public toilet (not shown in the figure), and each toilet is connected to a tap water pipe (not shown in the figure). After flushing the toilet, the water in the tap water pipe will flush the feces in the toilet through the sewer pipe 2 into the sewer main pipe 1. Since the sewer main pipe 1 is in an inclined state, the feces falling into the sewer main pipe 1 will be discharged. The feces and water in the water main 1 will flow toward the sewage collecting box 8 due to gravity, and finally the feces and water in the sewer main 1 will be discharged into the feces storage chamber 10 through the sewage inlet 13. After the feces and water enter the feces storage chamber 10, the feces will be deposited at the bottom of the feces storage chamber 10 due to gravity. As the feces and water in the sewer main 1 are continuously discharged, the liquid level in the feces storage chamber 10 will gradually increase. When the liquid level in the feces storage chamber 10 is higher than the notch 15 on the partition 9, the liquid in the feces storage chamber 10 will fall into the liquid collecting tank 16 in the liquid storage chamber 11 through the notch 15. When the liquid in the liquid collecting tank 16 gradually increases, the weight of the liquid collecting tank 16 will increase. Finally, the liquid collecting tank 16 will overcome the pressure of the elastic pressure piece and drive the sealing valve 7 to move horizontally through the traction transmission rope 20. When the sealing valve 7 After the horizontal movement, the drain port 6 is opened, and the water in the water storage tank 3 will flow into the sewer main pipe 1 through the drain port 6, so that the sewer main pipe 1 is flushed by the water in the water storage tank 3 to prevent feces from adhering to the sewer main pipe 1 and being difficult to discharge. When the liquid collecting tank 16 descends, the drainage valve 18 arranged on the liquid collecting tank 16 will gradually move downward close to the top pin 19 in the drainage tank 17. When the top pin 19 contacts the drainage valve 18, the top pin 19 will push the drainage valve 18 open, so that the liquid in the liquid collecting tank 16 will flow into the drainage tank 17. Among them, when the liquid in the liquid collecting tank 16 is discharged, the water discharged from the water storage tank 3 will continue to flow into the feces storage chamber 10, and then the liquid in the feces storage chamber 10 will fall into the liquid collecting tank 16 through the gap 15 again. The liquid flow rate is greater than the flow rate discharged from the drain valve 18, so when the water in the water tank 3 is drained, as the liquid in the collecting tank 16 decreases, the elastic pressure piece will drive the sealing valve 7 again to block the drain port 6, and at the same time the collecting tank 16 will be pulled up by the traction transmission rope 20. Since the feces flowing into the feces storage chamber 10 will be deposited at the bottom of the feces storage chamber 10 due to gravity, most of the feces will not flow into the collecting tank 16 through the gap 15 with the liquid, and only a small part of the feces will flow into the collecting tank 16 with the liquid, and the feces flowing into the collecting tank 16 will not affect the normal collection and discharge of water in the collecting tank 16. When a certain amount of feces is stored in the feces storage chamber 10, it is necessary to regularly extract the feces in the feces storage chamber 10. At this time, the sealing plug 14 on the feces extraction port 12 is pulled out.Then the feces extraction pipe is inserted into the feces storage chamber 10 through the feces extraction port 12, and the feces in the feces storage chamber 10 are finally extracted. In actual installation, the water storage tank 3 and the rainwater collection mechanism 4 are both installed on the top of the public toilet (not shown in the figure), and the sewer pipe 2 and the sewer main pipe 1 are both buried underground. Since the sewage collection box 8 is arranged below the sewer main pipe 1, when installing the sewage collection box 8, an installation pit (not shown in the figure) needs to be dug on the ground. The installation pit is covered with a sealing door (not shown in the figure), and a through hole is left on the sealing door for the traction transmission rope 20 to pass through.

[0050] In order to show the specific structure of the elastic pressure piece, the following features are set:

[0051] The elastic pressure member includes two fixing rods 21 and two No. 1 springs 22 (such as Figure 4 As shown in the figure, each fixing rod 21 is horizontally arranged below the water tank 3, one end of each fixing rod 21 is fixedly connected to the bottom of the water tank 3 through the vertical connecting plate 23, the two fixing rods 21 are symmetrical about the drain port 6, the sealing valve 7 horizontally covers the drain port 6, a socket 24 is formed at the bottom of the water tank 3, one end of the sealing valve 7 is inserted into the socket 24, and two sliding sleeves 25 are fixedly arranged on the other end of the sealing valve 7, each sliding sleeve 25 slides on the corresponding fixing rod 21, two No. 1 springs 22 are respectively sleeved on the two fixing rods 21, a No. 1 limiting nut 26 is screwed on the end of each fixing rod 21 away from the vertical connecting plate 23, a No. 2 limiting nut 27 is screwed on the end of each fixing rod 21 close to the vertical connecting plate 23, both ends of each No. 1 spring 22 are respectively in conflict with the sliding sleeve 25 and the No. 1 limiting nut 26, and each sliding sleeve 25 is in conflict with the No. 2 limiting nut 27.

[0052] In the initial state, each No. 1 spring 22 releases its elastic force, so that the No. 1 spring 22 will drive the sliding sleeve 25 to press against the corresponding No. 2 limit nut 27. At this time, the sealing valve 7 will completely seal the drain port 6. When the liquid collecting tank 16 is connected to the sealing valve 7 through the traction transmission rope 20, the sealing valve 7 will tend to move laterally due to the gravity of the liquid collecting tank 16. However, at this time, the elastic force of the two No. 1 springs 22 is greater than the gravity of the liquid collecting tank 16, so the current sealing valve 7 will not be displaced. When the liquid in the liquid collecting tank 16 gradually increases, the weight of the liquid collecting tank 16 increases, and the liquid collecting tank 16 will drive the sealing valve 7 to move laterally through the traction transmission rope 20, and finally the sealing valve 7 will open the drain port 6.

[0053] In order to specifically show how the water discharged from the drain port 6 flows into the sewer main 1, the following features are set:

[0054] A drainage bucket 28 covering the sealing valve 7 is fixedly provided at the bottom of the water storage tank 3, the conical mouth of the drainage bucket 28 faces downward, and a No. 1 water pipe 29 inclined downward is connected to the conical mouth of the drainage bucket 28, the lower end of the No. 1 water pipe 29 is connected to a vertical No. 2 water pipe 30, and the lower end of the No. 2 water pipe 30 is connected to the starting end of the sewer main 1.

[0055] When the drain port 6 is opened, the water in the water tank 3 flows into the drain bucket 28 through the drain port 6. Through the centralized drainage of the drain bucket 28, the water in the drain bucket 28 will flow into the sewer main pipe 1 through the No. 1 water pipe 29 and the No. 2 water pipe 30 in turn. The water flowing into the sewer main pipe 1 will flush out the feces attached to the sewer main pipe 1 that is difficult to be discharged automatically, and finally prevent the accumulation of feces and cause blockage of the sewer main pipe 1.

[0056] In order to show the specific installation method of the liquid collecting tank 16, the following features are set:

[0057] The top of the dirt collecting box 8 is provided with an installation opening 31 which is in communication with the liquid storage chamber 11, and a horizontal cover plate 32 (such as Fig.23 As shown, the liquid storage chamber 11 is provided with two guide slide bars 33 which are equidistantly distributed along the width direction of the dirt collecting box 8, and each guide slide bar 33 is vertical (as shown in FIG. Fig.15 As shown in the figure, the lower end of each guide slide rod 33 is fixedly connected to the bottom of the liquid storage chamber 11, and the liquid collecting tank 16 is horizontally arranged between the two guide slide rods 33. The cross section of the liquid collecting tank 16 is U-shaped. Both ends of the liquid collecting tank 16 are fixedly provided with guide sleeves 34, and each guide sleeve 34 is sleeved on the corresponding guide slide rod 33. A guide plate 35 located below the notch 15 is fixedly provided on the side of the partition plate 9 facing the liquid storage chamber 11. The guide plate 35 is tilted downward to introduce the liquid into the liquid collecting tank 16.

[0058] The liquid in the manure storage chamber 10 will fall downward into the liquid collecting tank 16 through the guide plate 35 after flowing through the notch 15. When the liquid in the liquid collecting tank 16 gradually increases, the liquid collecting tank 16 will descend. At this time, the guide sleeve 34 provided at the end of the liquid collecting tank 16 will slide on the corresponding guide slide rod 33. Finally, the lifting and lowering of the liquid collecting tank 16 is realized through the cooperation of the guide sleeve 34 and the guide slide rod 33. The partition 9, the liquid collecting tank 16 and the drainage tank 17 are conveniently installed in the liquid storage chamber 11 through the installation port 31 at the top of the sewage collecting box 8.

[0059] In order to specifically demonstrate how the traction drive rope 20 connects the sump 16 and the sealing valve 7, the following features are provided:

[0060] Two horizontal support plates 36 are fixedly provided in the liquid collecting tank 16, respectively close to the two ends of the liquid collecting tank 16, and a vertical pole 37 is fixedly provided on each horizontal support plate 36. A cross bar 38 is provided between the two vertical poles 37, and the cross bar 38 connects the upper ends of the two vertical poles 37. A fixing ring 39 is provided on the sealing valve 7, and a avoidance opening 40 is opened at the upper end of the drainage bucket 28. A No. 1 guide wheel 41 is provided above the sewage collecting box 8. The traction transmission rope 20 passes around the No. 1 guide wheel 41 from above, and one end of the traction transmission rope 20 passes through the avoidance opening 40 horizontally and is connected to the fixing ring 39, and the other end of the traction transmission rope 20 passes through the horizontal cover plate 32 vertically downward and is connected to the cross bar 38.

[0061] When the liquid in the feces storage chamber 10 flows into the liquid collecting tank 16, the liquid collecting tank 16 will begin to descend due to the weight of the liquid. When the liquid collecting tank 16 descends, the liquid collecting tank 16 will pull one end of the traction transmission rope 20 downward, so that the other end of the traction transmission rope 20 will pull the sealing valve 7 through the fixing ring 39, and finally the sealing valve 7 will open the drain outlet 6. The No. 1 guide wheel 41 can be installed on the ceiling of the public toilet during installation.

[0062] In order to show the specific structure of the drain valve 18, the following features are set:

[0063] The bottom of the liquid collecting tank 16 is provided with a through opening 42. The liquid drain valve 18 includes a valve tube 43, a valve pin 44, a stop sleeve 45 and a second spring 46. The valve tube 43 is vertical. The upper end of the valve tube 43 is fixed in the through opening 42. The lower end of the valve tube 43 is tapered. The stop sleeve 45 is vertically arranged in the upper end of the valve tube 43 (such as Fig. 9 As shown in the figure, a number of No. 1 connecting rods 47 evenly distributed along the circumferential direction of the limiting sleeve 45 are provided between the limiting sleeve 45 and the valve tube 43, each No. 1 connecting rod 47 connects the limiting sleeve 45 and the valve tube 43, and a valve pin 44 is provided in the valve tube 43. The valve pin 44 includes a tapered plug 48 and a sliding pin 49. The tapered plug 48 blocks the lower end of the valve tube 43 downwardly, and the sliding pin 49 is vertically fixed to the top of the tapered plug 48, and the sliding pin 49 passes through the limiting sleeve 45 upwardly, and a No. 2 spring 46 is sleeved on the sliding pin 49, and the two ends of the No. 2 spring 46 are respectively in conflict with the limiting sleeve 45 and the tapered plug 48.

[0064] In the initial state, the second spring 46 generates elastic force to push the conical plug 48 downward to block the lower end of the valve tube 43. At this time, the liquid in the liquid collecting tank 16 cannot be discharged downward through the valve tube 43. When the liquid in the liquid collecting tank 16 gradually increases, the liquid collecting tank 16 will overcome the elastic force of the first spring 22 and gradually descend. When the liquid collecting tank 16 descends to the point where the conical plug 48 contacts the ejector pin 19, the conical plug 48 will be pushed up by the ejector pin 19. In this process, the conical plug 48 will press upward. The No. 2 spring 46 is retracted. When the conical plug 48 is separated from the lower end of the valve tube 43, the liquid in the liquid collecting tank 16 will be discharged downward into the drain tank 17 through the valve tube 43. When the liquid in the liquid collecting tank 16 is gradually discharged, the weight of the liquid collecting tank 16 decreases, so that the liquid collecting tank 16 will be pulled up again by the traction transmission rope 20. During this process, the conical plug 48 is separated from the top pin 19, and the No. 2 spring 46 will drive the conical plug 48 downward to seal the lower end of the valve tube 43 again.

[0065] In order to show the specific installation method of the ejector pin 19, the following features are set:

[0066] The drain groove 17 is provided with a trustee 50 located directly below the valve pipe 43. The trustee 50 is coaxial with the valve pipe 43 and is fixed in the drain groove 17 by a bracket 51 (such as Fig.14 As shown in the figure, the ejector pin 19 is coaxially arranged in the trustee tube 50, and a plurality of No. 2 connecting rods 52 are arranged between the ejector pin 19 and the trustee tube 50 and are evenly distributed along the circumferential direction of the ejector pin 19. Each No. 2 connecting rod 52 connects the ejector pin 19 and the trustee tube 50. A convex ring 53 that can be downwardly mounted on the trustee tube 50 is formed on the outer surface of the valve tube 43.

[0067] When the liquid collecting tank 16 descends, the valve tube 43 will gradually approach the trust tube 50. During this process, the push pin 19 pushes up the tapered plug 48 to open the lower end of the valve tube 43. Finally, the liquid in the liquid collecting tank 16 will flow downward into the drain tank 17 through the valve tube 43. In the process of the liquid collecting tank 16 descending, the trust tube 50 is used to limit the descending stroke of the liquid collecting tank 16. When the convex ring 53 on the valve tube 43 is downwardly mounted on the trust tube 50, the entire liquid collecting tank 16 will stop descending to prevent the liquid collecting tank 16 from colliding with the drain tank 17.

[0068] In order to show how the liquid in the drainage groove 17 and the gas generated by the feces in the liquid storage chamber 11 are discharged, the following features are set:

[0069] A drain pipe 54 is formed at one end of the drain groove 17 and passes through the dirt collecting box 8. An exhaust pipe 55 (such as a gas exhaust pipe 55) is formed on the side wall of the dirt collecting box 8 and is located above the drain pipe 54. Fig.23 as shown).

[0070] In actual use, a sewage tank (not shown in the figure) and a biogas tank (not shown in the figure) are installed on the side of the sewage collecting box 8. The liquid flowing from the liquid collecting tank 16 into the drainage tank 17 will eventually be discharged into the sewage tank through the drainage pipe 54. The feces left in the feces storage chamber 10 for a long time will produce biogas, and the generated biogas will flow into the liquid storage chamber 11 through the gap 15. The biogas entering the liquid storage chamber 11 will enter the biogas tank through the exhaust pipe 55. Among them, the sewage tank is used to temporarily store sewage discharged from the sewage collecting box 8. The sewage in the sewage tank needs to be regularly pumped out and transported to the sewage processing plant. The biogas tank is used to temporarily store biogas. The biogas in the biogas tank needs to be regularly pumped out and transported to the gas processing plant.

[0071] In order to show the specific structure of the rainwater collection mechanism 4, the following features are set:

[0072] The rainwater collection mechanism 4 includes a water collection trough 56, a rainwater drainage plate 57 and a filter. The water collection trough 56 is arranged obliquely above the water storage tank 3, and the water collection trough 56 is in an inclined state (such as Fig.19 As shown in the figure, the lowest end of the water collecting trough 56 faces the water storage tank 3, the filter element is arranged in the water collecting trough 56, the lowest end of the water collecting trough 56 is connected to the rainwater inlet 5 through the curved pipe 58, and the top of the water collecting trough 56 is provided with a semi-sealing plate 59 close to the lowest end of the water collecting trough 56, the semi-sealing plate 59 blocks half of the opening at the top of the water collecting trough 56, and the rainwater drainage plate 57 is fixed to the side of the water collecting trough 56 in an inclined state, and the rainwater flows to the other half of the opening of the water collecting trough 56 through the rainwater drainage plate 57.

[0073] When it rains, rainwater will flow into the water collection trough 56 along the rainwater drainage plate 57, and the rainwater flowing into the water collection trough 56 will flow into the water storage tank 3 along the water collection trough 56 by its own gravity. During the flow of rainwater in the water collection trough 56, the filter will intercept foreign matter mixed with rainwater, so as to ensure that the water flowing into the water storage tank 3 does not contain foreign matter, and prevent foreign matter from clogging the sewer main 1. In actual processing, a tap water connecting pipe 66 (such as Figure 1 As shown), the tap water connecting pipe 66 is used to connect to the municipal water pipe. When there is no rain for a long time, water can be added to the water storage tank 3 through the municipal water pipe, ultimately ensuring that the water storage tank 3 is regularly filled with water.

[0074] In order to show the specific structure of the filter element, the following features are set:

[0075] The highest end of the water collection tank 56 is an open structure, and the filter element includes a filter plate 60, a slide plate 61, a gravity ball 62, a pull rope 63 and a second guide wheel 64. The slide plate 61 slides in the water collection tank 56, and the sliding direction of the slide plate 61 is consistent with the length direction of the water collection tank 56. The slide plate 61 is located above the semi-sealed plate 59. The filter plate 60 is fixed on the end of the slide plate 61 away from the water storage tank 3, and the filter plate 60 is perpendicular to the slide plate 61 (such as Fig.21As shown in the figure, the gravity ball 62 is fixedly connected to the side of the filter plate 60 facing the water tank 3 through a soft rope 65, the second guide wheel 64 is arranged on the side of the water collection trough 56, and the pull rope 63 passes around the second guide wheel 64 from above, one end of the pull rope 63 is connected to the slide plate 61, and the other end of the pull rope 63 hangs down.

[0076] In the initial state, the gravity ball 62 drives the filter plate 60 to slide to the lowest end of the water collection trough 56 by gravity. During this process, the slide plate 61 will slide above the semi-sealed plate 59, and finally the filter plate 60 will conflict with one end of the semi-sealed plate 59. When rainwater flows into the water collection trough 56, rainwater and foreign matter will flow through the filter plate 60. At this time, the filter plate 60 will block the foreign matter in the rainwater, and the rainwater will flow to the lowest end of the water collection trough 56 through the filter plate 60. After the filter plate 60 blocks more foreign matter, the drooping end of the pull rope 63 is pulled downward. During this process, the pull rope 63 will drive the slide plate 61 toward the highest end of the water collection trough 56. The filter plate 60 will scrape the intercepted foreign matter toward the highest end of the water trough 56, and the foreign matter in the water trough 56 will eventually fall out of the opening at the highest end of the water trough 56, and when the slide plate 61 slides, the slide plate 61 will gradually block the other half of the opening at the top of the water trough 56, so as to prevent foreign matter from outside from falling into the water trough 56. When the foreign matter in the water trough 56 is discharged, the pull rope 63 is released, and the gravity ball 62 will drive the slide plate 61 to slide toward the lowest end of the water trough 56 due to gravity until the filter plate 60 collides with one end of the half-sealed plate 59 again, wherein the No. 2 guide wheel 64 can be installed on the top of the public toilet.

[0077] Working principle:

[0078] The rainwater collecting mechanism 4 discharges the collected rainwater into the water storage tank 3 through the rainwater inlet 5. Since the sealing valve 7 is in a normally closed state, the rainwater entering the water storage tank 3 at this time will not be discharged through the drain port 6. When the sealing valve 7 closes the drain port 6, the liquid collecting tank 16 will be pulled to an ascending state by the traction transmission rope 20. At this time, the gravity of the liquid collecting tank 16 is less than the pressure of the elastic pressure piece, so the liquid collecting tank 16 will remain in an ascending state. The upper end of each sewer pipe 2 leads to a toilet in the public toilet (not shown in the figure), and each toilet is connected to a tap water pipe (not shown in the figure). After flushing the toilet, the water in the tap water pipe will flush the feces in the toilet through the sewer pipe 2 into the sewer main pipe 1. Since the sewer main pipe 1 is in an inclined state, the feces falling into the sewer main pipe 1 will be discharged. The feces and water in the water main 1 will flow toward the sewage collecting box 8 due to gravity, and finally the feces and water in the sewer main 1 will be discharged into the feces storage chamber 10 through the sewage inlet 13. After the feces and water enter the feces storage chamber 10, the feces will be deposited at the bottom of the feces storage chamber 10 due to gravity. As the feces and water in the sewer main 1 are continuously discharged, the liquid level in the feces storage chamber 10 will gradually increase. When the liquid level in the feces storage chamber 10 is higher than the notch 15 on the partition 9, the liquid in the feces storage chamber 10 will fall into the liquid collecting tank 16 in the liquid storage chamber 11 through the notch 15. When the liquid in the liquid collecting tank 16 gradually increases, the weight of the liquid collecting tank 16 will increase. Finally, the liquid collecting tank 16 will overcome the pressure of the elastic pressure piece and drive the sealing valve 7 to move horizontally through the traction transmission rope 20. When the sealing valve 7 After the horizontal movement, the drain port 6 is opened, and the water in the water storage tank 3 will flow into the sewer main pipe 1 through the drain port 6, so that the sewer main pipe 1 is flushed by the water in the water storage tank 3 to prevent feces from adhering to the sewer main pipe 1 and being difficult to discharge. When the liquid collecting tank 16 descends, the drainage valve 18 arranged on the liquid collecting tank 16 will gradually move downward close to the top pin 19 in the drainage tank 17. When the top pin 19 contacts the drainage valve 18, the top pin 19 will push the drainage valve 18 open, so that the liquid in the liquid collecting tank 16 will flow into the drainage tank 17. Among them, when the liquid in the liquid collecting tank 16 is discharged, the water discharged from the water storage tank 3 will continue to flow into the feces storage chamber 10, and then the liquid in the feces storage chamber 10 will fall into the liquid collecting tank 16 through the gap 15 again. The liquid flow rate is greater than the flow rate discharged from the drain valve 18, so when the water in the water tank 3 is drained, as the liquid in the collecting tank 16 decreases, the elastic pressure piece will drive the sealing valve 7 again to block the drain port 6, and at the same time the collecting tank 16 will be pulled up by the traction transmission rope 20. Since the feces flowing into the feces storage chamber 10 will be deposited at the bottom of the feces storage chamber 10 due to gravity, most of the feces will not flow into the collecting tank 16 through the gap 15 with the liquid, and only a small part of the feces will flow into the collecting tank 16 with the liquid, and the feces flowing into the collecting tank 16 will not affect the normal collection and discharge of water in the collecting tank 16. When a certain amount of feces is stored in the feces storage chamber 10, it is necessary to regularly extract the feces in the feces storage chamber 10. At this time, the sealing plug 14 on the feces extraction port 12 is pulled out.Then the feces extraction pipe is inserted into the feces storage chamber 10 through the feces extraction port 12, and the feces in the feces storage chamber 10 are finally extracted. In actual installation, the water storage tank 3 and the rainwater collection mechanism 4 are both installed on the top of the public toilet (not shown in the figure), and the sewer pipe 2 and the sewer main pipe 1 are both buried underground. Since the sewage collection box 8 is arranged below the sewer main pipe 1, when installing the sewage collection box 8, an installation pit (not shown in the figure) needs to be dug on the ground. The installation pit is covered with a sealing door (not shown in the figure), and a through hole is left on the sealing door for the traction transmission rope 20 to pass through.
