Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic machinery and cable fixing accessories, in particular to a deep well submersible pump cable fixing device installed along a pipe wall. Background Art

[0002] At present, there are two ways to fix the cable of deep well submersible pumps. One is to tie and fix along the well wall through embedded parts or expansion nails on the well wall, and the other is to tie and fix along the outlet steel pipe of the submersible pump with iron wire or cable ties. Fixing along the well wall will cause the cable to be unfixed in the deep well before it can be lifted out during water pump maintenance. When the water level in the deep well is high, diving operations are still required, which poses a personal safety hazard and is inefficient. Installation along the outlet steel pipe is due to factors such as the cable's own weight, water flow impact, steel pipe vibration, oxidation corrosion, etc., especially in a hydraulic environment with flow, the cable fixing tie or iron wire is extremely easy to break, causing the cable to swing with the water flow after being freed from the restraint, and the friction between the cable and the steel pipe flange, and the cable and the cable accidentally wear each other, reducing insulation, and even water seeping into the motor. The safety is poor and the use effect is very low. Utility Model Content
