A cable protector for cables of electric submersible pumps Technical field

[0001] The utility model relates to a cable protector, in particular to a cable protector for cables of electric submersible pumps. Background technique

[0002] The electric submersible pump cable is a cable used to connect the electric submersible pump and the upper part of the oil well. The working conditions of the electric submersible pump in the oil well are harsh, often in high temperature, high pressure, and highly corrosive environments containing oil and gas. Moreover, because the cable installation location is generally narrow, and the connections of oil pipes, submersible pumps, etc. usually have connecting flange protrusions, the cables located in this part will be severely worn, resulting in a reduction in the service life of the cables. Utility model content

[0003] The purpose of the present utility model is to provide a cable protector for cables of electric submersible pumps in order to solve the above-mentioned problems.

[0004] The utility model achieves the above purpose through the following technical solutions:

[0005] A cable protector for cables of electric submersible pumps, comprising a layered protector and a connecting rod, the layered protector is provided with a vertical through hole, and the connecting rod passes through the A plurality of said layered protectors are fixed and connected remotely through holes, said layered protectors include a fixed half sleeve, a movable half sleeve, a rotating shaft and a fixing device, and the fixed half sleeve and the movable half sleeve can be composed A semi-cylinder with a cylindrical structure, the first end of the fixed half sleeve is rotatably connected with the first end of the movable half sleeve through the rotating shaft, and the second end of the fixed half sleeve is connected to the movable half sleeve. The second end is detachably connected by the fixing device, the fixed half sleeve and the movable half sleeve are both provided with through holes, and the central axis of the through hole is parallel to the central axis of the fixed half sleeve.

[0006] Specifically, the upper end surfaces of the fixed half sleeve and the movable half sleeve are both provided with arc-shaped positioning grooves, and the lower end surfaces of the fixed half sleeve and the movable half sleeve are provided with the arc-shaped positioning grooves. The arc-shaped positioning edge corresponding to the groove.

[0007] Further, the cable protector further includes a fixing bolt, the connecting rod is a screw, and a plurality of the fixing bolts are sleeved on the connecting rod and located between two adjacent layered protectors. between.

[0008] Specifically, the fixing device includes a fixing screw and a fastening bolt, the second end of the fixed half sleeve and the movable half sleeve are both provided with a trapezoidal groove, and a fixed through hole is provided on the trapezoidal groove, The fixing screw passes through the fixing through hole and is fixedly connected to the fastening bolt.

[0009] The beneficial effects of the present utility model are:

[0010] The utility model is a cable protector for the cable of a submersible electric pump to protect the cable through a plurality of layered protectors. At the same time, the number of layered protectors can be adjusted according to the length of the cable part that needs to be protected, At the same time, through the cooperation of the fixed half sleeve and the movable half sleeve, the layered protector is easy to be fixed or removed, and the installation is convenient, which can effectively prevent the cable of the electric submersible pump from being worn out.
