Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and specifically relates to a water conservancy and hydropower construction drainage structure and method. Background Art

[0002] During the construction of water conservancy and hydropower, foundation pit excavation is carried out. The foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage work should be done well.

[0003] Before carrying out water conservancy and hydropower construction in the operation area, the accumulated water at the operation site needs to be drained to avoid hindering the workers during construction and to reduce safety hazards. However, there are usually a large amount of impurities in the accumulated water at the operation site, which poses a great challenge to the drainage equipment.

[0004] In order to ensure drainage efficiency, it is usually necessary to filter the pumping pipes to prevent impurities from being transmitted to the pump and causing blockage. Although the existing water conservancy and hydropower construction drainage structure can filter the drainage pipeline through a fine filter structure to prevent impurities from clogging the pipes and pump bodies, in actual use, the filter structure is easily clogged by debris. In order to ensure drainage efficiency, the drainage filter structure needs to be cleaned frequently. Summary of the invention

[0005] The purpose of the present invention is to address the problem of low drainage efficiency caused by the filter structure of the existing water conservancy and hydropower construction drainage structure being easily blocked by debris during actual use. A water conservancy and hydropower construction drainage structure and method are proposed, which can quickly drain the accumulated water in the water conservancy and hydropower construction area, and can filter impurities in the water to prevent them from being introduced into the drainage pump body and causing blockage. A cleaning component is provided to facilitate cleaning of intercepted impurities, and a plurality of recyclable drainage filter components are provided, which can be recycled, thereby ensuring the working efficiency of the water conservancy and hydropower construction drainage work.

[0006] In order to solve the above technical problems, the present invention provides a drainage structure and method for water conservancy and hydropower construction, including: a transport frame, a large-flow drainage pump, a sewage collecting box, a filter box, and a pumping head. The large-flow drainage pump is fixedly installed on the top of the transport frame, the transport frame is fixedly installed with a load-bearing bracket, the sewage collecting box is placed in the load-bearing bracket, the sewage collecting box is fixedly connected with a sewage valve, the transport frame is fixedly installed with a support frame, the support frame is fixedly connected to the filter box, the filter box is fixedly installed with a rotating motor, the driving end of the rotating motor is fixedly connected with a filter cartridge, the filter cartridge is evenly opened with filter holes, the inner wall of the filter hole is fixedly installed with a fine filter screen, and the filter box is fixedly installed with a blowing air filter. The blower is fixedly connected with a blow hopper, the filter box is fixedly connected with a connecting pipe, the connecting pipe is fixedly connected with a sewage collecting box, the large-flow drainage pump is fixedly connected with a drainage pipe and a water pumping pipe, the water pumping pipe is fixedly connected with the filter box, the filter box is fixedly connected with a connecting pipe, the connecting pipe is fixedly connected with a water pumping head, the inner wall of the water pumping head is provided with a conveying chamber and a sealing chamber, the conveying chamber is rotatably connected with a crushing roller, two crushing rollers are provided, the two crushing rollers are fixedly installed with transmission gears, the transmission gears on both sides are meshed and connected, the sealing chamber is fixedly installed with a rotating motor, the driving end of the rotating motor is fixedly connected with the crushing roller, and the water pumping head is fixedly installed with a primary filter screen; The method of use includes the following steps: S1: Move the high-flow drainage pump to the drainage area through the transport frame, select a connecting pipe of appropriate length to connect with the pumping head according to the depth of the water source, and put the pumping head into the water to start the high-flow drainage pump for drainage operation; S2: The water outside the pumping head is pumped into the conveying chamber of the pumping head through the primary filter. The primary filter can preliminarily filter the impurities in the water to prevent large-volume debris from entering. The rotating motor is started to rotate the crushing roller. The transmission gears of the two crushing rollers are meshed and connected, so that the crushing rollers on both sides can rotate in the conveying chamber to crush the impurities in the water, thereby performing preliminary treatment when the water is pumped in, thereby ensuring smooth drainage; S3: Water is transported to the filter box through the connecting pipe, and then to the pumping pipe through the filter holes of the filter cartridge. The fine filter in the filter holes can filter the impurities in the water for a second time, thereby preventing the impurities in the water from entering the large-flow drainage pump and causing blockage. The large-flow drainage pump can discharge the extracted water through the drainage pipe, thereby meeting the drainage needs and facilitating subsequent construction. S4: When the filter cartridge in the filter box filters water, the rotating motor is started to rotate the filter cartridge at a constant speed, so that the filter holes in the filter cartridge corresponding to the connecting pipe and the water pumping pipe can be recycled, and impurities can be collected in the filter holes under the filtering effect of the fine filter mesh. When the filter cartridge rotates, it can drive the impurities in the filter holes to move until they are connected with the connecting pipe. The air blower can blow air to the filter holes through the air blowing hopper, so that the impurities in the filter holes can be quickly introduced into the sewage collecting box for collection under the action of gravity and wind force, and the sewage discharge valve can be opened to discharge them uniformly for treatment.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Preferably, the sealed cavity is provided with a rotating hole corresponding to the crushing roller, and the inner wall of the rotating hole is rotatably connected to the crushing roller via a sealed bearing, so that the crushing roller can rotate more stably in the sealed cavity to crush the passing materials.

[0009] Preferably, the primary filter is configured as an arc-shaped structure, which has a larger contact area with the water body, making water source pumping smoother.

[0010] Preferably, the upper and lower sides of the filter cartridge are tightly fitted with the inner wall of the filter box and are rotatably connected to the filter box, so that the filter cartridge can stably rotate in the filter box.

[0017] 4. The large-flow drainage pump of this scheme can discharge the extracted water through the drainage pipe, thus meeting the drainage needs and facilitating subsequent construction.

[0018] 5. This solution starts the rotating motor to rotate the filter cartridge at a constant speed when filtering water in the filter cartridge in the filter box, so that the filter holes in the filter cartridge corresponding to the connecting pipe and the water pumping pipe can be recycled, and impurities can be collected in the filter holes under the filtering action of the fine filter mesh, so that the impurities in the extracted water source can be filtered without affecting the pump body.

[0019] 6. The filter cartridge of this scheme can drive the impurities in the filter holes to move when rotating until it is connected with the connecting pipe.
