Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy drainage pumps, in particular to a drainage pump for water conservancy projects that is convenient to adjust. Background Art

[0002] A drainage pump is a device used to drain liquid from a sump or a large liquid storage tank. The application scenarios of drainage pumps are very extensive, covering multiple fields such as building drainage, flood control and drainage, agricultural irrigation, and urban sewage treatment.

[0003] When draining water in a water conservancy project, since the drainage pump needs to be placed in water, and there is silt at the bottom of the water pit, in order to avoid the silt being sucked into the drainage pump, it is necessary to adjust the placement position of the drainage pump. Based on this, a drainage pump for water conservancy projects that is convenient to adjust is proposed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a drainage pump for water conservancy projects that is convenient to adjust, effectively solving the deficiencies of the prior art.

[0005] To achieve the above purpose, an embodiment of one aspect of the utility model provides a drainage pump for water conservancy projects that is convenient to adjust, including an inclined placement frame with a hollow design in the middle. Two support legs are installed on both sides of the placement frame. A first wire mesh is installed on the bottom surface of the placement frame. A guide frame is installed in the middle of the top surface of the placement frame. A fixed seat that climbs along its length direction is installed inside the guide frame, and a drainage pump body is installed at its top end. A lead screw is installed in the middle of the guide frame and is threadedly connected to the bottom surface of the fixed seat. One end of the lead screw is rotatably installed with a flexible shaft. A second wire mesh is installed at the edge of the top surface of the placement frame.

[0006] Preferably, according to any of the above solutions, hollow blocks are installed on both sides of the placement frame, and the bottom surfaces of all four are open. The four hollow blocks are respectively sleeved on the top ends of the four support legs and locked with bolts. One side of the four hollow blocks in this solution is fixedly connected to both sides of the placement frame by welding, providing installation positions for the four support legs, and the four support legs are fixedly connected to each other by connecting rods to ensure that the support legs are placed parallel to each other, facilitating the stable support of the placement frame.

[0007] Preferably, according to any of the above solutions, both sides of the inner wall of the guide frame are recessed inward. The two sides of the guide frame are fixedly connected to the top surface of the placement frame through angle codes. Using this solution facilitates the stable installation of the guide frame at the top surface position of the placement frame. At the same time, the placement frame is designed with a hollow structure, enabling water to flow upward from the bottom surface of the placement frame, facilitating the water pumping operation of the drainage pump body. Meanwhile, the guide frame facilitates guiding the movement of the fixed seat to prevent the fixed seat from shifting during operation.

[0008] Preferably, according to any of the above solutions, rollers are installed at the four corners of the bottom surface of the fixed frame. The four rollers are respectively in rolling connection with the two sides of the guide frame. Using this solution facilitates the relative rolling of the four rollers with the two sides of the guide frame, thereby limiting the position of the fixed frame. At the same time, it reduces the resistance of the fixed frame during operation, facilitating the operator to drive the relative rotation between the lead screw and the bottom surface of the fixed seat by rotating the flexible shaft.

[0009] Preferably, according to any of the above solutions, fixed semi - rings are installed on both sides of the top surface of the fixed seat. Both ends of the two fixed semi - rings are fixedly connected to the top end of the fixed seat through fasteners. Using this solution facilitates locking the position of the drainage pump body, enabling the drainage pump body to be placed parallel to the guide frame. At the same time, a hose is installed at the water outlet end of the drainage pump body, and the hose facilitates providing a flow channel for water flow, facilitating the pumping of accumulated water to a designated position.

[0010] Preferably, according to any of the above solutions, one end of the flexible shaft is rotationally connected to one end of the lead screw through a pin. An operating rod is installed at the other end of the flexible shaft. Using this solution facilitates providing a gripping position for the operator, and then driving the relative rotation between the lead screw and the bottom surface of the fixed seat through the operating rod, driving the fixed seat to move along the guide frame to change the installation position of the drainage pump body.

[0011] Preferably, according to any of the above solutions, both sides of the first wire mesh and the second wire mesh are fixedly connected to the placement frame through bolts. Two hollow protective tubes are installed at one end of the second wire mesh close to the flexible shaft. In this solution, strip flat irons are installed at the contact positions between the first wire mesh and the second wire mesh and the placement frame, and the bolts penetrate the strip flat irons, thereby facilitating locking the positions of the four sides of the first wire mesh and the second wire mesh to ensure the stability of the installation.

[0012] The utility model has the following advantages:

[0013] 1. The drainage pump for water conservancy projects that is easy to adjust is provided with a placement rack and four support legs, which facilitates the inclined placement of the placement rack. By setting a guide rack, a lead screw, and a mounting seat, the mounting seat is installed inside the guide rack, and at the same time, the drainage pump body is installed at the top of the mounting seat. Then, the whole is placed inside the puddle. The lead screw is driven to rotate by a flexible shaft, driving the mounting seat and the drainage pump body to move along the guide rack, raising the relative height of the drainage pump body to avoid the drainage pump body from sucking in silt. Moreover, the overall structure is simple and reasonably designed, facilitating popularization and use.

[0014] 2. The drainage pump for water conservancy projects that is easy to adjust is provided with a placement rack with a hollow middle part. At the same time, a second wire mesh and a first wire mesh are respectively installed on the upper and lower surfaces of the placement rack, which facilitates the filtering function, avoiding foreign objects in the water from entering the interior of the drainage pump body, ensuring the stable drainage. By setting four hollow blocks, which cooperate with the tops of the four support legs, it is convenient for the preliminary installation and subsequent disassembly, reducing the space occupation and facilitating transportation.
