Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage facilities, in particular to an intelligent diversion well with a lifting function. Background Art

[0002] In municipal drainage systems, in areas with combined sewer systems where there are no conditions for rainwater and sewage separation, interception facilities are often installed downstream of the combined sewer to intercept sewage on sunny days to prevent direct discharge and pollution of natural water bodies. After interception, the sewage pipes are generally buried too deep to drain downstream by gravity, so a lift pump station is required to lift the intercepted sewage and discharge it to the downstream sewage pipe network, and ultimately to the sewage treatment plant. Common problems include:

[0003] 1. The intercepting well and the lifting pump station are set up separately, which occupies a large area and has a high project cost.

[0004] 2. The interception multiple of traditional interception wells cannot be adjusted, and the actual interception effect is poor. There are often phenomena such as incomplete sewage interception or excessive interception of rainwater, which increases the load on the sewage treatment plant.

[0005] Based on this, the scheme was improved and an intelligent diversion well with lifting function was proposed, which has both interception and lifting functions, compact structure and low cost. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an intelligent diversion well with a lifting function in view of the deficiencies of the above-mentioned prior art.

[0007] The technical solution of the utility model for solving the above technical problems is as follows: an intelligent diversion well with a lifting function, the intelligent diversion well is divided into an intercepting area and a lifting area, the intercepting area and the lifting area are connected by an intercepting pipe, and an inlet pipe and an outlet pipe are respectively provided on the side walls on opposite sides of the intercepting area. An intercepting mechanism is provided on the passage between the inlet pipe and the outlet pipe in the intercepting area, and a lifting mechanism is provided in the lifting area. A sewage pipe is provided on the side wall of the lifting area away from the water inlet pipe, and a valve is provided on the pipeline between the lifting mechanism and the sewage pipe. A trash screen is provided at the position corresponding to the intercepting pipe between the intercepting area and the lifting area.

[0008] The beneficial effects of the present invention are as follows: the intelligent diversion well with a lifting function of the present invention integrates interception and lifting functions by rationally zoning the functions of the diversion well structure, thereby reducing the number of structures, saving land, optimizing interception facilities, and reducing project costs. The interception mechanism is set up to intercept sewage and initial rainwater according to different water levels and rainwater quality at different stages, thereby achieving precise sewage interception and diversion, improving the interception effect, and cooperating with the lifting mechanism to lift the intercepted sewage and discharge it into the downstream sewage pipe. The structure is simple and convenient for construction and installation.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows:

[0010] Further: the interception area is divided into an inlet area and a drainage area, the inlet pipe is connected and arranged on the side wall on one side of the inlet area, the outlet pipe is arranged in the drainage area, one end of the outlet pipe is connected to the water inlet area, and the other end of the outlet pipe extends out of the side wall on one side of the drainage area, the interception mechanism is arranged on the outlet pipe and is located in the drainage area.

[0011] The beneficial effect of the above further scheme is: by dividing the interception area into an inlet area and a drainage area, it is convenient for rainwater to enter the inlet area, and cooperate with the interception mechanism, lifting mechanism and valve to realize interception and diversion of rainwater at different water levels and different stages of water quality, which is convenient for operation and independent control of each functional area.

[0012] Furthermore: the intercepting mechanism adopts a bottom-opening weir gate, a gate or a flexible intercepting sleeve.

[0013] The beneficial effect of the above further solution is that the use of a bottom-opening weir gate, a gate or a flexible interception sleeve can facilitate the closing and opening of the outlet pipe, thereby achieving the sewage interception function.

[0014] Further: A first liquid level gauge is provided on the inner side wall of the water inlet area.

[0015] The beneficial effect of the above further solution is that by setting the first liquid level gauge, the water level in the water inlet area can be detected in real time, which serves as a basis for controlling the intercepting mechanism, lifting mechanism and valve, thereby achieving accurate sewage interception and diversion.

[0016] Furthermore: the lifting area is divided into a water collection area and a sewage discharge area, the lifting mechanism is arranged in the water collection area, the valve is arranged in the sewage discharge area, and the water collection area is connected to the water inlet area through the intercepting pipe.

[0017] The beneficial effect of the above further scheme is: by dividing the lifting area into a water collection area and a sewage discharge area, it is convenient for the sewage intercepted from the interception area to enter the water collection area, and be lifted by the lifting mechanism, and discharged to the downstream sewage pipe through the sewage pipe in conjunction with the valve, and it is convenient to control the lifting mechanism and valve separately to realize the independence of each functional area.

[0018] Further: the lifting mechanism includes at least one water pump unit, each water pump unit is connected to the sewage pipe respectively, the valves are the same in number as the water pump units and correspond one to one, and the valves are arranged on the pipeline between the sewage pipe and the corresponding water pump unit.

[0019] The beneficial effect of the above further scheme is: by setting up the water pump unit, the intercepted sewage can be lifted, and the intercepted sewage can be discharged into the downstream sewage pipe through the sewage pipe in conjunction with the corresponding valve, which is very convenient, and the operation of part or all of the water pump units can be controlled according to different water volumes, which is very convenient.

[0020] Further: A second liquid level gauge is provided on the inner wall of the water collection area.

[0021] The beneficial effect of the above further solution is that by providing the second liquid level meter, the water level in the water collection area can be conveniently detected in real time, thereby accurately controlling the lifting mechanism and the valve.

[0022] Furthermore: the tops of the interception area and the lifting area are respectively provided with manhole covers that can be opened or closed.

[0023] The beneficial effect of the above further solution is that by providing the manhole cover, later inspection and maintenance can be facilitated, the convenience of operation is improved, and the maintenance cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] like Figures 1 to 3As shown, an intelligent diversion well with a lifting function is provided. The intelligent diversion well is divided into an intercepting area and a lifting area. The intercepting area and the lifting area are connected by an intercepting pipe 4. An inlet pipe 1 and an outlet pipe 2 are respectively provided on the side walls on opposite sides of the intercepting area. An intercepting mechanism 3 is provided on the passage between the inlet pipe 1 and the outlet pipe 2 in the intercepting area. A lifting mechanism 7 is provided in the lifting area. A sewage pipe 9 is connected to the side wall of the lifting area away from the water inlet pipe 1. A valve 8 is provided on the pipeline between the lifting mechanism 7 and the sewage pipe 9. A trash screen 5 is provided at the position corresponding to the intercepting pipe 4 between the intercepting area and the lifting area.

[0031] The intelligent diversion well with lifting function of the present invention integrates interception and lifting functions by rationally zoning the functions of the diversion well structure, reducing the number of structures, saving land, optimizing interception facilities, and reducing project costs. The interception mechanism 3 is set to intercept sewage and initial rainwater according to different water levels and rainwater quality at different stages, thereby achieving precise sewage interception and diversion, improving the interception effect, and cooperating with the lifting mechanism 7 to lift the intercepted sewage and discharge it into the downstream sewage pipe. The structure is simple and convenient for construction and installation.

[0032] In one or more embodiments of the present invention, the interception area is divided into an inlet area and a drainage area, the inlet pipe 1 is connected and arranged on the side wall of the inlet area, the outlet pipe 2 is arranged in the drainage area, one end of the outlet pipe 2 is connected to the inlet area, and the other end of the outlet pipe 2 extends out of the side wall of the drainage area, and the interception mechanism 3 is arranged on the outlet pipe 2 and located in the drainage area. By dividing the interception area into an inlet area and a drainage area, it is convenient for rainwater to enter the inlet area, and the interception mechanism 3, the lifting mechanism 7 and the valve 8 are used to intercept and divert rainwater at different water levels and different stages of water quality, which is convenient for operation and also facilitates independent control of each functional area.

[0033] In practice, one end of the outlet pipe 2 can be directly set in the drainage area, or it can pass through the partition wall between the drainage area and the water inlet area and be connected to the water inlet area. In both cases, the intercepting mechanism 3 can be set on the outlet pipe 2 and located in the water inlet area.

[0034] Optionally, in one or more embodiments of the present invention, the interception mechanism 3 is a bottom-opening weir gate, gate, or flexible interception sleeve. Using a bottom-opening weir gate, gate, or flexible interception sleeve can facilitate closing and opening the outlet pipe 2, thereby achieving a sewage interception function.

[0035] Of course, in practice, it is not limited to the above three types, and the settings can be flexibly selected according to the actual situation.

[0036] In one or more embodiments of the present invention, a first liquid level gauge 2 is provided on the inner sidewall of the water inlet area. The first liquid level gauge 2 can detect the water level in the water inlet area in real time, thereby serving as a basis for controlling the interception mechanism 3, the lifting mechanism 7, and the valve 8, thereby achieving precise sewage interception and diversion.

[0037] In one or more embodiments of the present invention, the lifting area is divided into a water collection area and a sewage discharge area, the lifting mechanism 7 is disposed in the water collection area, the valve 8 is disposed in the sewage discharge area, and the water collection area is connected to the water inlet area via the intercepting pipe 4. By dividing the lifting area into the water collection area and the sewage discharge area, sewage intercepted from the intercepting area can be easily introduced into the water collection area, lifted by the lifting mechanism 7, and discharged into the downstream sewage pipe through the sewage pipe 9 in conjunction with the valve 8. It is also convenient to independently control the lifting mechanism 7 and the valve 8, thereby achieving the independence of each functional area.

[0038] In practice, the trash screen 5 of this embodiment is arranged on the side wall of the water collection area and faces the intercepting pipe 4, so as to filter the sewage flowing from the intercepting pipe 4 and intercept scum, etc., to ensure that the sewage does not block the downstream pipe.

[0039] In one or more embodiments of the present invention, the lifting mechanism 7 includes at least one water pump unit, each of which is connected to the sewage pipe 9. The valves 8 are provided in the same number as the water pump units and correspond one to one with each other, and the valves 8 are provided in the pipeline between the sewage pipe 9 and the corresponding water pump unit. The provision of the water pump units facilitates lifting the intercepted sewage and, in conjunction with the corresponding valves 8, discharges the intercepted sewage through the sewage pipe 9 into the downstream sewage pipe, which is very convenient. Furthermore, the operation of some or all of the water pump units can be controlled according to different water volumes, which is also very convenient.

[0040] Here, when multiple water pump units are provided, the operation of each water pump unit can be controlled separately according to the actual water level.

[0041] In one or more embodiments of the present invention, a second liquid level gauge 10 is provided on the inner wall of the water collection area. The second liquid level gauge 10 facilitates real-time detection of the water level in the water collection area, thereby enabling precise control of the lifting mechanism 7 and the valve 8.

[0042] In one or more embodiments of the present invention, the tops of the interception area and the lifting area are respectively provided with openable or closable manhole covers 6. The provision of the manhole covers 6 facilitates later inspection and maintenance, improves operational convenience, and reduces maintenance costs.

[0043] The intelligent diversion well with a lifting function of the present invention has a shutoff mechanism 3 that is closed on sunny days or at the beginning of rainfall, so that sewage on sunny days or at the beginning of rainfall can enter the water collection area through the shutoff pipe 4, and enter the downstream sewage pipe through the sewage pipe 9 controlled by the lifting mechanism 7 and the valve 8. The shutoff mechanism 3 is opened in the middle and late stages of rainfall, and the sewage and initial rainwater are intercepted by adjusting the opening of the shutoff mechanism 3, so that the relatively clean water outlet pipe 2 is directly discharged to the downstream water body.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
