Description

Technical Field

[0001] The utility model relates to the technical field of submersible pump cable protectors, in particular to a submersible pump cable protector with a fixed structure. Background Art

[0002] Submersible pump cable protector is a device specially designed to protect submersible pump cables from mechanical damage, chemical corrosion and environmental factors. During oil well exploitation, submersible electric pumps are placed deep in the oil well, and the electric energy is transmitted through the cable to drive the submersible motor to work and extract the crude oil from the well. Due to the harsh environment downhole, such as high temperature, high pressure, corrosive media, etc., and the cable may be subjected to mechanical stress such as stretching, bending, and scratching during the lowering and use process, the cable protector is particularly important.

[0003] The submersible pump cable protection bracket is a type of submersible pump cable protector. The protection bracket mainly supports and protects the cable in the submersible electric pump system to prevent the cable from being damaged due to force, friction, stretching or bending when it is lowered into the oil well or during underground operations. This bracket can be designed as an independent component and installed at an appropriate position on the cable path to ensure that the cable is maintained in a relatively safe space when it is lowered into the well and in operation, reducing direct contact with the well wall, thereby extending the service life of the cable.

[0004] In the prior art, the diameter of the fixing ring structure of the submersible pump cable protection bracket is usually fixed. For cables of different diameters, the diameter of the fixing ring cannot be adjusted, which means that it can only adapt to cables of specific sizes. If the cable diameter is slightly different, the fixing ring may not provide sufficient tightening force, resulting in loose cable fixation, or excessive tightening may cause unnecessary stress damage to the cable.

[0012] As a preferred embodiment of the submersible pump cable protector with a fixed structure of the utility model, the internal thread of the mounting block is connected with a plurality of screws.
