Description

Technical Field

[0001] The utility model relates to the technical field of rural domestic sewage and rainwater treatment, in particular to rural domestic sewage and rainwater diversion equipment. Background Art

[0002] Rural domestic sewage treatment removes harmful substances and environmental pollutants from domestic sewage, degrading them to a harmless state. Rural sewage treatment can neutralize water quality and agricultural products based on actual conditions, enabling reuse and environmentally friendly degradation. Because rural drainage systems are mostly combined sewers, farmers' domestic sewage, rainwater from courtyards and roofs, wastewater from washing livestock pens, drainage from village road sweeping, and farmland irrigation all flow into a single sewer system. This results in significant fluctuations in the quality and volume of drainage water between the dry and rainy seasons, necessitating separate treatment for domestic sewage and rainwater.

[0003] A rural domestic sewage and rainwater diversion device with announcement number CN221627222U describes that "when it is not raining, the elastic mechanism raises the lifting cylinder to the highest point. At this time, the second baffle blocks the rainwater outlet, and the first baffle opens the sewage outlet. Domestic sewage enters the diversion cylinder from the water inlet and is discharged from the sewage outlet into the sewage treatment system; when it rains, the rain collecting pan collects enough rainwater, and then the full-open pressure relief valve discharges the collected water into the lifting cylinder. The weight of the lifting cylinder filled with water increases and compresses the spring of the elastic mechanism, causing the lifting cylinder to drop to the lowest point. At this time, the passage The hole is aligned with the rainwater outlet, and the first baffle closes the sewage outlet, thereby draining the rainwater into the rainwater treatment system; the rainwater diversion can be automatically triggered when it rains to complete the diversion of rainwater and sewage. The device uses the gravity of water to make the elastic mechanism drive the lifting cylinder to rise and fall and reset. However, as the water in the rain collecting pan continues to flow away, the spring will drive the lifting cylinder to reset. Only when a certain gravity of rainwater is collected in the rain collecting pan again will the lifting cylinder be pressed down again, making it difficult for the rainwater outlet to maintain the open state for a long time. The unstable opening and closing greatly affects the diversion effect of rainwater and sewage. Utility Model Content

[0004] The purpose of the utility model is to provide a rural domestic sewage and rainwater diversion device. By setting a fixed frame, a sliding column, a plug plate, a gear and a toothed plate and other structures, when the water level sensor in the rain barrel detects that the water level reaches the standard, the sliding column can drive the two plug plates to move relative to each other in the socket, so that one of the plug plates descends and seals the sewage pipe, while the other plug plate rises to open the rainwater pipe, so that the rainwater falling into the ditch can flow into the rainwater treatment system through the water inlet pipe and the rainwater pipe. Conversely, by controlling the two plug plates to rise and fall in the opposite direction, the rainwater pipe can be closed and the sewage pipe can be opened at the same time, and then the sewage in the ditch can be passed into the sewage treatment system through the water inlet pipe and the sewage pipe. It is not only simple to operate, but also convenient to switch the diversion, and stable and efficient, and greatly ensures the diversion effect of sewage and rainwater, so as to solve the above-mentioned shortcomings in the technology.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] The utility model provides Figures 1-4 A rural domestic sewage and rainwater diversion device is shown, comprising:

[0026] A water inlet pipe 1, one end of which is connected to a sewage pipe 2, and the other end of which is connected to a rainwater pipe 3. A rainwater collecting cylinder 6 is fixedly connected to the upper end of the water inlet pipe 1 through a bracket. A water level sensor 8 is provided in the rainwater collecting cylinder 6, and an outlet pipe 21 is connected between the rainwater collecting cylinder 6 and the water inlet pipe 1;

[0027] The top of the rain receiving tube 6 is provided with a rain inlet, and the top of the rain inlet is provided with a second filter screen 7. Can prevent impurity from falling in the rain receiving tube 6 by the second filter screen 7.

[0028] A first filter screen 4 is provided at one end of the rainwater pipe 3 opposite to the water inlet pipe 1 .

[0029] A discharge pipe 5 is provided at the bottom of the rainwater pipe 3, between the first filter screen 4 and the insert plate 16. Both the discharge pipe 5 and the outlet pipe 21 are equipped with control valves. The first filter screen 4 prevents dirt carried in rainwater from passing through the rainwater pipe 3 and into the rainwater treatment system. The discharge pipe 5 allows any impurities that are intercepted to be discharged.

[0030] The fixed frame 9 is arranged between the water inlet pipe 1 and the rain collecting cylinder 6, and movable support columns 12 are symmetrically provided on both sides of the interior of the fixed frame 9. The bottom ends of the two support columns 12 are connected to sliding columns 15. Both sides of the fixed frame 9 are provided with chutes 14 matching the sliding columns 15. The two sliding columns 15 extend to one end of the outside of the fixed frame 9 and are provided with plug-ins 16. The top sides of the sewage pipe 2 and the rainwater pipe 3 are provided with sockets 19 facing the plug-in plates 16, and the bottom ends of the plug-in plates 16 are inserted into the sockets 19.

[0031] A drive motor 10 is fixed in the middle of the side wall of the fixed frame 9. The output end of the drive motor 10 extends into the fixed frame 9 and is connected to a gear 11. The side walls of the two support columns 12 are fixed with a gear plate 13 that meshes with the gear 11.

[0032] When in use, rainwater can be received through the rain tube 6, and the water level sensor 8 in the rain tube 6 can detect the water level. Once the water level reaches the set value, the drive motor 10 can be started, and the drive motor 10 drives the gear 11 to rotate, so that the gear 11 drives the toothed plates 13 on both sides to engage and move. The toothed plates 13 can drive the support column 12 to move, so that the support column 12 drives the sliding column 15 to slide in the chute 14, so that the sliding column 15 can drive the two plugs 16 to move relative to each other in the socket 19, so that one of the plugs 16 descends and seals the sewage pipe 2, while the other plug 16 rises to open the rainwater pipe 3, so that the rainwater falling into the ditch can flow into the rainwater treatment system through the water inlet pipe 1 and the rainwater pipe 3, and the rainwater in the rain tube 6 can be passed into the rainwater pipe 3 through the outlet pipe 21;

[0033] On the contrary, by controlling the two plug plates 16 to rise and fall in opposite directions, the rainwater pipe 3 can be closed while the sewage pipe 2 is opened, so that the sewage in the ditch can be passed into the sewage treatment system through the water inlet pipe 1 and the sewage pipe 2. This is not only simple to operate, but also convenient in diversion switching, and stable and efficient, which greatly ensures the diversion effect of sewage and rainwater.

[0034] In addition, when it first starts to rain, the domestic sewage mixed with rainwater remaining in the rural drainage ditches is still a high-concentration sewage, and the debris washed away by the rainwater is also mixed in the sewage. At this time, the sewage is still discharged from the sewage pipe 2 to the sewage treatment system. The rainwater pipe 3 can only be opened when the rain collecting cylinder 6 collects and detects enough rainwater. During this period, the rainwater washes away most of the debris and domestic sewage, thereby further ensuring the diversion effect of rainwater and sewage.

[0035] A clamping strip 17 is fixed to the bottom end of each of the two inserting plates 16 , and a clamping slot 18 matching the clamping strip 17 is provided on the inner bottom side of each of the sewage pipe 2 and the rainwater pipe 3 .

[0036] A sealing ring 20 is provided on the inner side of the socket 19. The sealing ring 20 can be used to provide a waterproof seal.

[0037] By engaging the clamping strip 17 and the clamping groove 18 with each other and cooperating with the sealing ring 20 , the sealing performance of the plug plate 16 when closing the pipeline can be greatly enhanced.

[0038] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
