Description

Technical Field

[0001] The utility model relates to the technical field of overflow well structure design, in particular to a sponge city overflow well structure. Background Technique

[0002] During rain, the green space in the sponge city absorbs, stores, seeps, and purifies water. When needed, the stored water is released and utilized to realize the benign migration of rainwater in urban development. It improves the urban water environment and enhances the ability to cope with the risk of urban waterlogging. At present, with the continuous deepening of the concept of sponge city construction, rainwater overflow wells are widely used. In the prior art, the practicability and structure of rainwater overflow wells are simplified accordingly to be applicable to conventional sponge city construction.

[0003] At present, the application purpose of rainwater overflow wells in sponge city green spaces is to realize the normal drainage of site rainwater while playing the role of precipitating suspended pollutants. At present, the commonly used rainwater overflow wells in sunken green spaces generally use grid plates or vertical gratings to precipitate suspended pollutants. However, due to the large grid bar spacing of the grid plates or vertical gratings, they mainly intercept larger impurities (such as branches, leaves, etc.) and cannot intercept relatively fine impurities. In the long run, there will be problems of sediment deposition blocking the drainage pipes of rainwater overflow wells.

[0004] The problems existing in the prior art are that when the overflow well is blocked by fine substances such as sediment, it can only rely on manual cleaning, which consumes a lot of manpower. If an automatic cleaning structure can be formed to eliminate manual labor or extend the cleaning cycle, the maintenance cost will be greatly reduced. Content of the Utility Model

[0005] In order to solve the above technical deficiencies, the utility model provides a sponge city overflow well structure.

[0006] The technical solution of the utility model: A sponge city overflow well structure, including a storage green space, an overflow well, a filter element assembly, a water inlet pipe, and a drain pipe. The overflow well includes a well seat, a well body, and a well cover. The well body includes an inlet. The well cover covers the inlet of the well body. The well cover is provided with a filter opening and a buoyancy arm extending into the well body. The buoyancy arm is made of buoyancy material. The water inlet pipe and the drain pipe are arranged in the well body and are both provided with electric control valves. The filter element assembly is detachably arranged between the buoyancy arm and the water inlet pipe and the drain pipe.

[0007] By adopting the above technical scheme, the larger scum and debris are filtered through the filter port of the manhole cover, and the water entering the well body is filtered through the filter core assembly to filter fine impurities, so as to prevent fine impurities from entering and clogging the drain pipe. After long-term use, fine impurities intercepted by the filtration will accumulate on the filter core assembly, causing the filter core assembly to be blocked. At this time, the structure closes the electric control valve of the drain pipe, opens the electric control valve of the water inlet pipe, and injects water into the well body to form a backwashing effect. The water injected into the water inlet pipe passes through the filter assembly to flush out fine impurities. As the water level in the well body rises, the buoyancy arm made of the buoyancy material set on the manhole cover is used to drive the manhole cover to rise and open the wellhead, so as to smoothly discharge the impurities out of the overflow well. After discharge, as the water inlet pipe is closed and the drain pipe is opened, the water level drops, and the manhole cover automatically falls and resumes the closed state.

[0008] This design can periodically control the electrically controlled valves of the water inlet pipe and the drain pipe to achieve the effects of backwash cleaning and lid opening and slag removal, thereby extending the manual maintenance cycle and reducing labor costs.

[0009] The utility model is further configured as follows: it also includes a three-way pipe, which is arranged between the filter element assembly and the drain pipe. The three-way pipe includes a bucket-shaped mouth facing one side of the filter element assembly, and the bucket-shaped mouth divides the well body into a filter chamber and a drain chamber. A water reservoir and a submersible pump are provided at the well seat. One of the three-way pipes on one side of the drain chamber is connected to the drain pipe, and the other is connected to the submersible pump.

[0010] By adopting the above technical solution, a water reservoir is set at the well seat, and daily rainwater enters the water reservoir through the three-way pipe for storage. During backwashing, the electric control valve of the drain pipe is closed, and the submersible pump in the pneumatic water reservoir is used to use the rainwater retained in the water reservoir for backwashing, saving water costs and the laying of water inlet pipes.

[0011] A further configuration of the utility model is that the manhole cover is provided with a plurality of buoyancy arms at intervals around the center of the circle.

[0012] By adopting the above technical solution, the buoyancy arms arranged at intervals form gaps so that fine impurities can be discharged with the water flow during backwashing, while maintaining the stability of the manhole cover during lifting and lowering, and maintaining coaxial lifting and lowering movement with the well body to avoid falling dislocation caused by tilting and the manhole cover not being completely closed.

[0013] A further configuration of the utility model is as follows: the storage green space is provided with a slag collecting trough around the overflow well.

[0014] A further configuration of the utility model is that the slag collecting trough is arranged in an inclined manner and comprises a vertical low point, and a filter screen is arranged at the notch of the vertical low point.

[0015] By adopting the above technical solution, a slag collecting trough is set up to receive the slag-carrying water flow overflowing during backwashing, and the inclined design is used to guide the slag-carrying water flow to converge at the vertical low point. At the same time, the filter screen separates the slag and water at the vertical low point and uniformly intercepts fine impurities to facilitate subsequent manual centralized cleaning and avoid backflow to the regulation and storage green space.

[0016] Beneficial effects of the utility model: The structural design of the overflow well of the present application can link together to form the effects of backwash cleaning and opening the cover to discharge slag by regularly controlling the electrically controlled valves of the water inlet pipe and the drain pipe. At the same time, the designed slag collecting trough can extend the manual maintenance cycle and reduce labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The filter port 231 of the manhole cover 23 is used to filter large scum and debris, and the water entering the well body 22 is filtered through the filter core assembly 3 to filter fine impurities, so as to prevent the fine impurities from entering and clogging the drain pipe 4. After long-term use, the fine impurities intercepted by the filtration will accumulate on the filter core assembly 3, causing the filter core assembly 3 to be blocked. At this time, the structure closes the electric control valve 41 of the drain pipe 4, opens the electric control valve 41 of the water inlet pipe, and injects water into the well body 22 to form a backwashing effect. The water injected into the water inlet pipe passes through the filter assembly to flush out the fine impurities. As the water level in the well body 22 rises, the filter port 232 made of the buoyancy material set on the manhole cover 23 is used to drive the manhole cover 23 to rise and open the wellhead, so as to smoothly discharge the impurities out of the overflow well 2. After discharge, as the water inlet pipe is closed, the drain pipe 4 is opened, the water level drops, and the manhole cover 23 automatically falls and resumes the closed state.

[0026] This design can periodically control the electric control valve 41 of the water inlet pipe and the drain pipe 4 to achieve the effects of backwash cleaning and lid opening and slag removal, thereby extending the manual maintenance cycle and reducing labor costs.

[0027] It also includes a three-way pipe 5, which is arranged between the filter element assembly 3 and the drain pipe 4. The three-way pipe 5 includes a bucket-shaped mouth 51 facing the side of the filter element assembly 3, and the bucket-shaped mouth 51 divides the well body 22 into a filter chamber 52 and a drainage chamber 53. A water reservoir 211 and a submersible pump 212 are provided at the well seat 21. One of the three-way pipes 5 on one side of the drainage chamber is connected to the drain pipe 4, and the other is connected to the submersible pump 212.

[0028] By setting up a water reservoir 211 at the well seat 21, daily rainwater enters the water reservoir 211 through the three-way pipe 5 for storage. During backwashing, the electric control valve 41 of the drain pipe 4 is closed, and the submersible pump 212 in the water reservoir 211 is pneumatically driven to use the rainwater retained in the water reservoir 211 for backwashing, thereby saving water use costs and the laying of water inlet pipes.

[0029] The manhole cover 23 is provided with a plurality of filter openings 232 at intervals around the center of the circle.

[0030] The filter ports 232 are arranged at intervals to form gaps so that fine impurities can be discharged with the water flow during backwashing, while maintaining the stability of the manhole cover 23 when it is raised and lowered, and maintaining the coaxial lifting movement with the well body 22 to avoid falling dislocation caused by tilting, and the manhole cover 23 is not completely closed.

[0031] The storage green space 1 is provided with a slag collecting trough 6 around the overflow well 2 .

[0032] The slag collecting tank 6 is arranged in an inclined manner and includes a vertical low point, and a filter screen 61 is arranged at the notch of the vertical low point.

[0033] The slag collecting trough 6 is set up to receive the slag-carrying water flow overflowing during backwashing, and the inclined design is used to guide the slag-carrying water flow to converge at the vertical low point. At the same time, the filter screen separates the slag and water at the vertical low point and uniformly intercepts fine impurities, which is convenient for subsequent manual centralized cleaning and avoids backflow to the storage green space 1.

[0034] The structural design of the overflow well 2 of the present application can form the effects of backwashing cleaning and opening the cover to discharge slag by regularly controlling the electric control valve 41 of the water inlet pipe and the drain pipe 4. At the same time, the designed slag collecting tank 6 can extend the manual maintenance cycle and reduce labor costs.

[0035] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
