[0002] When a centrifugal pump transports liquid, it needs to use the centrifugal force generated by the rotation of the impeller to make the liquid move centrifugally in order to operate. When the centrifugal pump is working, violent vibrations are generated due to the high-speed rotation of the impeller.

[0003] The existing method of shockproofing centrifugal pumps is to directly install them on the cement floor by bolting them. Not only is the operation cumbersome, but the bolts are also prone to loosening or rusting and getting stuck in a vibrating environment for a long time, thereby reducing the safety of the centrifugal pump during use. Therefore, a shockproof centrifugal pump is needed to improve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a shockproof centrifugal pump, which solves the problem that the conventional method of shockproofing a centrifugal pump is to directly fix it on a cement floor by bolts, which is not only cumbersome to operate, but also the bolts are prone to loosening or rusting and getting stuck in a vibrating environment for a long time, thereby reducing the safety of the centrifugal pump during use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shockproof centrifugal pump, comprising a placement plate, a centrifugal pump body is arranged on the placement plate, four first card frames are overlapped under the placement plate, four second card frames are overlapped under the placement plate, a limit plate is arranged in the second card frame, four card blocks are arranged under the placement plate, a limit groove is provided on the side of the card block, the limit plate is overlapped with the limit groove, a top plate is arranged under the first card frame, the second card frame is overlapped with the top plate, a sliding rod is slidably connected in the first card frame, a fixing plate is arranged at one end of the sliding rod, four buffer rubber columns are arranged under the top plate, and a damping shock absorber is arranged under the top plate.

[0006] As a further solution of the utility model: two sliding grooves are arranged on the top plate, and sliding blocks are slidably connected in the sliding grooves.

[0007] As a further solution of the present invention: the first clamping frame is overlapped with the second clamping frame, and the sliding block is connected to the second clamping frame.

[0008] As a further solution of the utility model: a spring is provided on the side of the slide rod, and one end of the spring is connected to the fixing plate.

[0009] As a further solution of the utility model: the other end of the spring is connected to the first clamping frame, and the other end of the sliding rod is connected to the second clamping frame.

[0010] As a further solution of the utility model: a connecting rod is provided on the side of the second clamping frame, the other ends of the two connecting rods are provided with a same connecting plate, and a pull rod is provided on the side of the connecting plate.

[0011] As a further solution of the utility model: a support plate is provided under the damping shock absorber, the support plate is connected to the buffer rubber column, and a mounting frame is provided under the support plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The shockproof centrifugal pump further avoids the situation that the bolts are easily loosened or rusted and stuck in a vibration environment for a long time by arranging the first clamping frame, the second clamping frame, the clamping block, the limit plate, the limit groove, the damping shock absorber and the buffer rubber column.

By setting the limiting groove 11 and the limiting plate 12, the limiting groove 11 is on the limiting plate 12 It plays a supporting and limiting role, so that the limiting plate 12 can move smoothly in the limiting groove 11. The limiting plate 12 overlaps the limiting groove 11. A connecting rod 6 is provided on the side of the second card frame 5. The other ends of the two connecting rods 6 are provided with the same connecting plate 7. A pull rod 8 is provided on the side of the connecting plate 7. By setting the pull rod 8 and the connecting plate 7, the connecting plate 7 supports and limits the pull rod 8, so that the pull rod 8 can move smoothly. At the same time, the pull rod 8 makes it more convenient for the staff to pull the second card frame 5.

[0021] A top plate 20 is provided under the first card frame 4, and two slide grooves 14 are provided on the top plate 20. A slider 13 is slidably connected in the slide groove 14. By setting the slide groove 14 and the slider 13, the slide groove 14 supports and limits the slider 13, thereby ensuring that the slider 13 will not shake randomly during the sliding process in the slide groove 14. The slider 13 is connected to the second card frame 5, and the second card frame 5 overlaps the top plate 20. A slide rod 16 is slidably connected in the first card frame 4, and a fixing plate 18 is provided at one end of the slide rod 16. A spring 17 is provided on the side of the slide rod 16. By setting the spring 17, the spring 17 can be elastically acted on so that The limit plate 12 is in close contact with the limit groove 11, one end of the spring 17 is connected to the fixed plate 18, the other end of the spring 17 is connected to the first clamping frame 4, the other end of the slide rod 16 is connected to the second clamping frame 5, four buffer rubber columns 3 are provided under the top plate 20, and a damping shock absorber 15 is provided under the top plate 20.

[0022] The working principle of the utility model is:

[0023] When in use, first install the installation frame 9 to a suitable position, then control the two pull rods 8 to move away from each other, so that the two pull rods 8 drive the two second card frames 5 to separate from the two first card frames 4, and the second card frames 5 drive the slide bar 16 and the fixed plate 18 to move, at this time the spring 17 is compressed, the two second card frames 5 drive the two limit plates 12 to move away from each other, and then control the placement plate 1 with the centrifugal pump body 2 to contact with the first card frame 4, and then the placement plate 1 drives the card block 10 to contact the first card frame 4;

[0024] When the clamping block 10 moves to the position of the limiting plate 12 in the limiting groove 11, the two pull rods 8 are released. In order to restore its own shape, the spring 17 drives the rod and the sliding rod 16 to reset, so that the sliding rod 16 drives the second clamping frame 5 and the limiting plate 12 to reset, until the limiting plate 12 is pushed into the limiting groove 11 and the centrifugal pump body 2 is successfully installed. At the same time, the buffer rubber column 3 and the damping shock absorber 15 work together to prevent it from shock.
