Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, and in particular to a centrifugal pump that is easy to load and unload. Background Technology

[0002] The working principle of a centrifugal pump is to use the rotation of the pump impeller to generate centrifugal force, which throws the fluid from the central area of ​​the pump to the periphery, thereby discharging the fluid.

[0003] When transporting a centrifugal pump, it is necessary to first move the pump onto a transport vehicle, then transport it to the required location, and finally unload it from the vehicle. The pump is moved using a hook on top of the pump along with ropes and other auxiliary tools. If these tools are lost, the pump is lifted by grabbing its protruding parts. However, when transporting on bumpy roads, the pump may tilt to one side. Since the protruding parts of the pump are limited, there is a risk of the pump slipping from one's grasp, potentially causing injury to both the equipment and personnel. Utility Model Content

Detailed Implementation

[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] This utility model provides, for example Figure 1-4 The centrifugal pump shown is easy to install and remove, including a pump body 1, a mounting base 2 fixedly connected to the bottom of the pump body 1, and also includes;

[0023] The lifting assembly 3 is used to transport the pump body 1. The lifting assembly 3 includes handles 301 symmetrically arranged on the front and back of the mounting base 2. Both ends of the handles 301 are fitted with positioning blocks 302. One end of the handles 301 and one side of the positioning block 302 is provided with a positioning plate 303 for fixing the position of the handles 301.

[0024] Positioning element 4 is located on one side of positioning block 302 and is used to restrict the rotation of handle 301.

[0025] It should be noted that the pump body 1 is an existing centrifugal pump. During use, the fluid enters the pump body 1 through the pump inlet. The fluid is accelerated by the rotation of the impeller, which converts mechanical energy into kinetic energy, increasing the fluid's speed and pressure. The accelerated fluid flows out through the pump's outlet, thus transporting the fluid. The mounting base 2 has positioning holes on both sides. When it is necessary to fix the position of the pump body 1, bolts are passed through the positioning holes to fix the position of the mounting base 2. The position of the pump body 1 is fixed by fixing the mounting base 2. The positioning block 302 is fixedly connected to one side of the mounting base 2. The handle 301 is inserted into the middle of the positioning block 302 and is restricted by the two positioning blocks 302. The positioning plate 303 is fixedly connected to the end of the handle 301. The restriction of the positioning plate 303 prevents the end of the handle 301 from moving out of the positioning block 302. The movement of the handle 301 is restricted by restricting the movement of the positioning plate 303. The positioning element 4 is used to restrict the rotation of the positioning plate 303 and restricts the rotation of the handle 301 by restricting the positioning plate 303.

[0026] Specifically, the positioning component 4 includes a plurality of positioning grooves 407 symmetrically opened on one side of the positioning disk 303. A positioning post 406 for limiting the rotation of the positioning disk 303 is inserted inside one of the positioning grooves 407. A driving block 405 is fixedly connected to one side of the positioning post 406. A limiting part 6 for limiting the rotation of the driving block 405 is provided at the bottom of the driving block 405.

[0027] It should be noted that the limiting part 6 is set to limit the rotation of the drive block 405. Multiple positioning grooves 407 are symmetrically opened on one side of the positioning disk 303. When it is necessary to limit the rotation of the positioning disk 303, the drive block 405 drives the positioning column 406 to move and insert the positioning column 406 into the positioning groove 407 on the positioning disk 303. The drive block 405, which limits the rotation, limits the movement of the positioning column 406. The positioning column 406, which limits the movement, limits the rotation of the positioning disk 303. Thus, the positioning disk 303, which limits the rotation, limits the rotation of the handle 301, preventing the handle 301 from shaking due to the vibration of the centrifugal pump when using the centrifugal pump.

[0028] Specifically, a fixing block 403 is fixedly connected to one side of the positioning block 302, and a fixing groove 5 is provided on one side of the fixing block 403. The driving block 405 is inserted into the inside of the fixing groove 5, and a screw 404 is threadedly inserted into the middle of the driving block 405. A rotating cap 401 for rotating the screw 404 is fixedly connected to one end of the screw 404. A connecting hole is provided on the inner wall of one side of the fixing groove 5, and the screw 404 is inserted into the inside of the connecting hole. A limiting ring 402 is provided on the inner wall of one side of the fixing groove 5, and the limiting ring 402 is sleeved on one side of the screw 404.

[0029] It should be noted that: the rotating cap 401 is fitted but not fixed to one side of the fixing block 403, and the limiting ring 402 is fitted but not fixed to the inner wall of one side of the fixing groove 5. The limiting ring 402 is fixedly sleeved on one side of the screw 404. In use, the rotating cap 401 and the limiting ring 402 restrict the movement of the screw 404. When the screw 404 needs to be rotated, the rotating cap 401 is used to rotate the screw 404. The outer wall of the rotating cap 401 has an anti-slip groove to increase the friction between the fingers and the rotating cap 401 when the screw 404 is rotated by the rotating cap 401, preventing the fingers from separating from the rotating cap 401. When the position of the driving block 405 needs to be moved, the rotating cap 401 drives the screw 404 to rotate, and the rotating screw 404 drives the threaded driving block 405, which cannot rotate, to move, and the driving block 405 drives the positioning post 406 to move.

[0030] Specifically, the limiting part 6 includes a guide rod 601 fixedly connected to the inner wall of one side of the fixing groove 5, and a guide groove 602 is provided at the bottom of the driving block 405, with the guide rod 601 inserted into the inside of the guide groove 602.

[0031] It should be noted that the screw 404 is threadedly connected to the middle of the drive block 405, and the guide rod 601 is threadedly connected to the guide groove 602 opened on the drive block 405. The rotation of the drive block 405 is restricted by the screw 404 and the guide rod 601, and the drive block 405 moves along the direction of movement of the guide rod 601 when it moves.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
