A prefabricated drainage well assembly for sewage separation

Abstract

This utility model relates to the field of drainage technology and discloses a prefabricated drainage well assembly for sewage diversion. It includes a drainage well body, an inlet pipe, a sewage pipe, and an overflow pipe fixedly penetrating the surface of the drainage well body. It also includes a baffle mechanism installed on one side of the inner wall of the drainage well body and a guide wheel rotatably connected to the inner wall of the drainage well body. This utility model allows adjustment of the state of the flapper plate by raising or lowering the water level. When the water level rises, the flapper plate rotates counterclockwise, and water is discharged through the overflow pipe. When the water level drops, the baffle plate rises, and sewage is discharged to a sewage treatment plant through the sewage pipe. This process relies on the natural force of water level fluctuations, eliminating the need for additional power resources and equipment. This solves the problem that some prefabricated drainage wells currently require power for diversion operations, which consumes additional resources, and the lifespan of electrical equipment is easily affected by prolonged exposure to damp areas.

Description

Technical Field

[0001] This utility model relates to the field of drainage technology, specifically to a prefabricated drainage well assembly for sewage diversion. Background Technology

[0002] Precast drainage wells are drainage facilities made using precast concrete technology, mainly used for urban drainage, rainwater collection, and sewage discharge.

[0003] Currently, some prefabricated drainage wells can control the opening and closing of hydraulic flow control gates according to the drainage volume, so as to separate sewage and rainwater. During the dry season and the first rain, sewage and initial rainwater discharged from the inlet pipe can be discharged through the drain pipe. As the rainfall continues, the water level in the well continues to rise, and sewage and a large amount of rainwater can be discharged through the overflow pipe. However, this process requires the cooperation of hydraulic flow control gates. Therefore, the use of this drainage well requires power support, which is relatively resource-intensive. In addition, the service life of electrical equipment is easily affected by being close to the water source for a long time. Utility Model Content

[0004] The purpose of this invention is to provide a prefabricated drainage well assembly for sewage diversion, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated drainage well assembly for sewage diversion, comprising a drainage well body, an inlet pipe fixedly penetrating the surface of the drainage well body, a sewage pipe, and an overflow pipe, and further comprising:

[0006] A shielding mechanism installed on one side of the inner wall of the drainage well body and a guide wheel rotatably connected to the inner wall of the drainage well body, wherein the surface of the guide wheel is provided with a guide rope;

[0007] Vertical plates are fixedly connected to both sides of the inner wall of the water inlet pipe. A partition is fixedly connected between the two vertical plates and a flip plate is hinged thereto. A cleaning mechanism is installed on the surface of the partition. A reinforcing plate is fixedly connected to the lower part of one side of the flip plate. A connecting mechanism is installed on the surface of the reinforcing plate.

[0008] Preferably, the shielding mechanism includes two side plates fixedly connected to one side of the inner wall of the drainage well body, a baffle slidably connected between the two side plates, L-shaped plates fixedly connected to the surfaces of both sides of the baffle, the surfaces of the L-shaped plates slidably connected to the inner walls of the side plates, a top plate fixedly connected to the top of the baffle, and one end of the guide rope fixedly connected to the top of the top plate.

[0009] Preferably, the thickness of the baffle is equal to the width of the side plate, and the surface of the baffle is slidably connected to the inner wall of the drainage well body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention allows for adjustment of the tilting plate's state by varying the water level. When the water level rises, the tilting plate rotates counterclockwise, allowing water to drain through the overflow pipe. When the water level drops, the baffle rises under gravity and with the help of guide ropes, allowing sewage to be discharged to a sewage treatment plant through the drain pipe. This process relies on the natural force of water level fluctuations, eliminating the need for additional power resources and equipment. It solves the problem that some prefabricated drainage wells currently require electricity for diversion operations, which consumes extra resources and can negatively impact the lifespan of electrical equipment when used in damp areas.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 As shown, a prefabricated drainage well assembly for sewage diversion includes a drainage well body 14, an inlet pipe 1, a sewage pipe 2, and an overflow pipe 3 fixedly penetrating the surface of the drainage well body 14. A shielding mechanism 4 is installed on one side of the inner wall of the drainage well body 14 and is rotatably connected to a guide wheel 12. A guide rope 11 is provided on the surface of the guide wheel 12. A top plate 5 is installed on the top of the shielding mechanism 4. The shielding mechanism 4 includes two side plates 41 fixedly connected to one side of the inner wall of the drainage well body 14. The two side plates 41 are respectively located on both sides of one end of the sewage pipe 2. A baffle 42 is slidably connected between the two side plates 41. L-shaped plates 43 are fixedly connected to the surfaces of both sides of the baffle 42. The surfaces of the L-shaped plates 43 are flush with the side plates 41. The inner wall of plate 41 is slidably connected, and the top plate 5 is fixedly connected to the top of baffle 42. The bottom of the top plate 5 is in contact with the top of the side plate 41. One end of the guide rope 11 is fixedly connected to the top of the top plate 5. When the guide rope 11 is pulled, it can drive the top plate 5 to rise. When the side plate 41 is raised, it can remove the obstruction of the sewage pipe 2, and the sewage can be discharged through the sewage pipe 2. When the pull of the guide rope 11 is released, the baffle 42 can move downward under the action of gravity. The thickness of the baffle 42 is equal to the width of the side plate 41. The surface of the baffle 42 is slidably connected to the inner wall of the drainage well body 14. After the baffle 42 is lowered, the water flow through the sewage pipe 2 can be reduced, reducing the burden on the sewage treatment plant.

[0023] When water accumulates and rises continuously inside the main body 14 of the drainage well, vertical plates 6 are fixedly connected to both sides of the inner wall of the inlet pipe 1. A partition 7 is fixedly connected between the two vertical plates 6 and a flip plate 8 is hinged thereto. A reinforcing plate 9 is fixedly connected to the lower part of one side surface of the flip plate 8. A connecting mechanism 10 is installed on the surface of the reinforcing plate 9. The connecting mechanism 10 includes a connecting frame 101 fixedly connected to the surface of the reinforcing plate 9. A moving block 102 is fixedly connected to one end of the connecting frame 101. The other end of the guide rope 11 is fixedly connected to the moving block 102. A protruding rod 103 is fixedly connected to one side surface of the moving block 102. A guide frame 104 is fixedly connected to one side of the inner wall of the main body 14 of the drainage well. The surface of the protruding rod 103 contacts the inner wall of the guide frame 104. The guide frame 104 guides the movement of the protruding rod 103, thereby guiding the movement of the moving block 102. The guide frame 104 and the protruding rod 103 can also limit the movement range of the guide rope 11.

[0024] When the water level is higher than the baffle 7, the water flow can exert force on the tilting plate 8 and push it. As the water level continues to rise, the tilting plate 8 continues to tilt and drive the connecting mechanism 10 to move. At this time, through the connection of the guide rope 11, the baffle 42 can be lowered and block the sewage pipe 2. A cleaning mechanism 13 is installed on the surface of the baffle 7. During the process of rising water level, the cleaning mechanism 13 is raised to filter impurities in the water and prevent impurities in the water from being discharged into the external water source through the overflow pipe 3. The cleaning mechanism 13 includes a fixed frame 131 fixedly connected to both sides of the surface of the baffle 7. The surface of the fixed frame 131 is slidably fitted with There is a lifting frame 132, and a cleaning net 133 is fixedly connected between the two lifting frames 132. The lifting net 133 can filter impurities in the water when it is raised. A floating plate 134 is fixedly connected to the surface of the lifting frame 132. During the process of water level rise, the floating plate 134 drives the cleaning net 133 to rise under the action of buoyancy. The water flows through the cleaning net 133 and pushes the flip plate 8 to flip. During this process, the cleaning net 133 intercepts impurities in the water, and a large amount of water is discharged through the overflow pipe 3. This can reduce the treatment burden of the sewage treatment plant and reduce the possibility of water accumulation on the ground when the water volume increases suddenly.

[0025] Working principle: Under normal circumstances, sewage and initial rainwater are discharged into the main body 14 of the drainage well through the inlet pipe 1, and then discharged through the sewage pipe 2. When the water volume suddenly increases, the sewage pipe 2 cannot quickly discharge the water source. At this time, the water level inside the main body 14 of the drainage well increases, and the floating plate 134 is lifted by buoyancy, which drives the cleaning net 133 to rise. The water flows out through the cleaning net 133 and squeezes the tilting plate 8. The water flows out through the gap between the tilting plate 8 and the baffle 7 and is discharged through the overflow pipe 3. When the tilting plate 8 is tilted by the impact of the water flow, the baffle 42 can be lowered and block the sewage pipe 2, reducing the burden on the sewage treatment plant. The cleaning net 133 separates impurities in the water and prevents impurities from being discharged to the outside with the overflow pipe 3. When the water level drops later, the tilting plate 8 can be tilted under the action of gravity. Figure 1 As shown in the diagram, the baffle 42 no longer blocks the drain pipe 2, and the sewage can be discharged again through the drain pipe 2.
