Description

Technical Field

[0001] This utility model relates to the field of cable wear prevention technology, specifically a submersible pump cable wear prevention elastic fixing base. Background Technology

[0002] A submersible pump is a type of water pump that operates underwater. It typically consists of a motor, impeller, and sealing devices. When the submersible pump starts, the motor drives the impeller to rotate rapidly, creating negative pressure that draws in water and discharges it through pipes. Submersible pumps are widely used in many fields, such as drainage, farmland irrigation, and aquarium circulation. A cable powering the motor is present on the submersible pump; when the pump is operating underwater, the cable also enters the water.

[0003] The cables on existing submersible pumps rely on external O-rings. The pressure generated by tightening the threads causes the O-rings to expand and achieve a seal. During operation, the cables shake and are impacted by water flow, causing rapid wear and damage at the cable connections. This results in poor protection, reduced service life of the submersible pump, and failure to meet usage requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a wear-resistant elastic fixing base for submersible pump cables, in order to solve the problem mentioned in the background art that the cables on existing submersible pumps rely on external O-rings. The pressure generated by tightening the threads causes the O-rings to expand and achieve a seal. However, during the operation of the submersible pump, the cables will shake and be subject to water flow impact, resulting in rapid wear and damage at the cable connection points. This leads to poor protection, reduced service life of the submersible pump, and failure to meet usage requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant elastic fixing base for a submersible pump cable, comprising a circular base, a cable, and a pump body. The pump body has a mounting hole. A first hollow tube is mounted at the lower end of the circular base, and a second hollow tube is mounted at the upper end of the circular base. The first and second hollow tubes are integrally formed with the circular base. A threaded groove is provided on the outer wall of the first hollow tube. The diameter of the first hollow tube is smaller than the diameter of the mounting hole, and the first hollow tube is slidably connected to the pump body. A first connecting cap is mounted on the outside of the first hollow tube and is threadedly connected to it. A sealing element is mounted below the circular base and is located outside the first hollow tube. The sealing element corresponds to the mounting hole. A cold shrink tubing is mounted on the outside of the cable and fits snugly against the cable. One end of the cold shrink tubing is fitted onto the outside of the second hollow tube.

[0006] Preferably, a sealing ring is installed inside the upper end of the second hollow tube, and the sealing ring is fixedly connected to the second hollow tube. The second hollow tube is disposed outside the cable and is in contact with the cable.

[0007] Preferably, a second connecting cap is installed below the first connecting cap, and the second connecting cap is threadedly connected to the first hollow tube, with the second connecting cap fitting snugly against the first connecting cap.

[0008] Preferably, a wire clamp is fixedly installed on the outside of the cable, and the wire clamp is installed below the first hollow tube, with the wire clamp in contact with the lower end of the first hollow tube.

[0009] Preferably, the upper end of the seal is provided with a protrusion, there are two protrusions, and the protrusions are integrated with the seal. The two protrusions are symmetrically arranged on the seal. The lower end of the annular base is provided with a groove, there are two grooves, and the protrusions are correspondingly arranged with the grooves. The protrusions are inserted into the annular base.

[0010] Preferably, a water-swellable ring is installed inside the mounting hole, and the water-swellable ring is fitted onto the outside of the first hollow tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model device uses a cold shrink tube, a sealing ring, and a wire clamp. The sealing ring ensures the sealing of the installed cable. One end of the cold shrink tube is fitted onto the outside of the connection between the cable and the second hollow tube and wraps around the cable to further improve the sealing of the cable installation. The cold shrink tube itself has a certain elasticity and support function, which can reduce the impact and shaking of the cable and reduce the wear and damage of the cable. The wire clamp provides unidirectional restraint for the cable installed in the pump body, restricting the cable from being pulled out of the pump body when the cable is pulled, thus improving the stability of the installed cable.

[0013] This utility model device, through the setting of a water-expanding ring, a first connecting cap, and a second connecting cap, connects the first connecting cap to the first hollow tube, compressing the seal. The second connecting cap connects to the first hollow tube and contacts the first connecting cap, limiting the first connecting cap and preventing it from loosening under stress, thus improving the connection between the fixed base and the pump body. When the water-expanding ring comes into contact with water, it expands rapidly, filling the gap between the first hollow tube and the pump body, further improving the connection sealing performance.
