[0002] Submersible pumps are important equipment for deep well water extraction. When in use, the entire unit submerges in the water to extract groundwater to the surface for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading, and fountain landscape.

[0003] However, most existing submersible pump structures do not have anti-collision structures. When the submersible pump is lowered into a deep well for use, the submersible pump is prone to collide with the inner wall of the deep well, thereby causing damage to the submersible pump and seriously affecting the service life of the submersible pump. Summary of the invention

[0004] The purpose of the utility model is to provide a new submersible pump to solve the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: a new submersible pump, including a submersible pump body, characterized in that a plurality of buffer devices are arranged on the outer peripheral wall of the submersible pump body for buffering when the submersible pump body collides with the inner wall of the deep well, and the plurality of buffer devices are arranged in sequence along the outer peripheral wall of the submersible pump body in a circumferential direction and are connected to the submersible pump body in a sliding limit position;

[0006] The buffer device comprises an anti-collision plate movably mounted on the outer peripheral wall of the submersible pump body, a plurality of buffer balls embedded in the anti-collision plate and used for buffering and reducing the impact strength, and a plurality of return springs for elastic return of the anti-collision plate;

[0007] A plurality of connection grooves for installing the anti-collision plate and the return spring are provided on the outer peripheral wall of the submersible pump body, and the connection grooves have a plurality of connection columns for the return spring to be sleeved and connected;

[0008] The side corresponding to the collision plate is provided with a limiting step, and the side wall of the slot opening of the connecting slot is provided with a limiting portion which cooperates with the limiting step.

[0009] In the above-mentioned novel submersible pump, the cross section of the anti-collision plate is arranged in an arc structure and is adapted to the outer peripheral wall of the submersible pump body, and the outer side of the anti-collision plate has a nano coating which reduces the impact strength and improves the compressive strength.

[0010] In the above-mentioned new submersible pump, the anti-collision plate is movably installed in the connecting groove, and the limiting part and the limiting step cooperate to achieve limiting. The anti-collision plate is elastically reset after being hit by a reset spring located in the connecting groove.

[0011] In the above-mentioned novel submersible pump, the buffer balls can be made of elastic rubber material, and a plurality of the buffer balls are arranged in sequence and at intervals along the side wall of the anti-collision plate.

[0012] Compared with the existing technology, this new submersible pump has the following advantages:

[0013] 1. By setting up the buffer device structure, the collision strength between the outer wall of the submersible pump body and the inner wall of the deep well is effectively reduced to the minimum, preventing the problem of damage to the outer wall and internal part of the submersible pump body caused by collision, and greatly extending the service life and use efficiency;

[0014] 2. Through the anti-collision plate and buffer ball structure setting, the collision strength between the submersible pump body and the inner wall of the deep well can be effectively buffered and unloaded radially, thus achieving effective protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1 , Figure 2 As shown, the new submersible pump comprises a submersible pump body 1, and a plurality of buffer devices are arranged on the outer peripheral wall of the submersible pump body 1 for buffering when the submersible pump body 1 collides with the inner wall of the deep well. The plurality of buffer devices are arranged in sequence along the outer peripheral wall of the submersible pump body 1 in a circumferential direction, and are connected to the submersible pump body 1 by sliding limit. The buffer device comprises an anti-collision plate 2 movably mounted on the outer peripheral wall of the submersible pump body 1, a plurality of buffer balls 3 embedded and mounted on the anti-collision plate 2 and used for buffering and reducing the impact intensity, and a plurality of reset springs 4 for elastic reset of the anti-collision plate 2. A plurality of connecting grooves 5 for installing the anti-collision plate 2 and the reset spring 4 are provided on the outer peripheral wall of the submersible pump body 1, the connecting groove 5 has a plurality of connecting columns 6 for sleeve connection of the reset spring 4, the corresponding side of the anti-collision plate 2 has a limit step 7, and a limit portion 8 cooperating with the limit step 7 is provided on the side wall of the groove of the connecting groove 5.

[0020] The structure is simple in design. By setting up a buffer device structure, the collision strength between the outer wall of the submersible pump body 1 and the inner wall of the deep well is effectively minimized, thereby preventing the problem of damage to the outer wall and interior of the submersible pump body 1 caused by collision, and greatly extending the service life and use efficiency. At the same time, the anti-collision plate 2 and the buffer ball 3 structural setting can effectively radially buffer and unload the collision strength between the submersible pump body 1 and the inner wall of the deep well, thereby achieving effective protection.

[0021] To further elaborate, in order to improve the impact resistance of the outer wall of the submersible pump body 1, the cross-section of the anti-collision plate 2 is arranged in an arc structure and is adapted to the outer wall of the submersible pump body 1, and the outer side of the anti-collision plate 2 has a nano-coating that reduces the impact strength and improves the compressive strength.

[0022] To elaborate further, in order to buffer the impact force, the anti-collision plate 2 is movably installed in the connecting groove 5, and the limiting part 8 and the limiting step 7 cooperate to achieve limiting. The anti-collision plate 2 is elastically reset after being impacted by the reset spring 4 located in the connecting groove 5.

[0023] To further elaborate, in order to improve the anti-collision capability, the buffer balls 3 can be made of elastic rubber material, and a plurality of buffer balls 3 are arranged in sequence and spaced apart along the side wall of the anti-collision plate 2 .

[0024] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0025] Although the terminology such as submersible pump body 1, anti-collision plate 2, buffer ball 3, return spring 4, connection groove 5, connection column 6, limit step 7, limit part 8 is used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
