Cable centralizer convenient to put in and recycle

Abstract

The invention relates to the technical field of cable installation equipment, and discloses a cable centralizer convenient to put in and recycle. The cable centralizer comprises a fixed clamping ringand a movable clamping ring, the outer side of the fixed clamping ring is fixedly connected with a hinge connecting piece, and the outer side of the hinge connecting piece is movably connected with aleft side supporting shaft. According to the cable centralizer convenient to put in and recycle, an assembled cable and the centralizer are put down to corresponding positions along a shaft, then thefirst drawing shafts are sequentially drawn out, at the moment, the dielectric rod is drawn out of the fixed clamping ring, the electromagnet is powered on to have magnetism and attract the magnet filling block, and the movable clamping ring gets close to the position of the fixed clamping ring. The left side supporting shaft and the right side supporting shaft support the wall-attached flitch upwards to enable the wall-attached flitch to be tightly attached to the inner wall of a correspondingly-installed wellbore to assist in fixing a cable, the installation structure is suitable for the wellbore with a small caliber, the stability of the installation structure is high, the operation process can be completed on the ground, underground work is reduced, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of cable installation equipment, in particular to a cable centralizer which is convenient for feeding and recycling. Background technique [0002] The water source well is a well drilled for the exploitation of groundwater. In the water source well, the cables and sensing lines of the downhole submersible pump are lowered into the well with the submersible pump outside the tubing. The friction and collision between the tubing and the casing may cause damage to the cables and sensing lines, resulting in downhole accidents and economic losses. The centralizer refers to the oil and gas drilling. Rigid and flexible centralizing frame installed centrally on the outer surface of the casing. [0003] Most of the centralizers currently used in the field are spring-type and lantern-shaped structures, which are divided into riveted and hinged types according to the structure. In smaller shafts, an adjustable telesco...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a cable centralizer that is convenient for feeding and recycling, which can be automatically retracted and returned, convenient for feeding and recycling, easy to operate, and has the advantages of improving the progress of the project and solving the problems of the telescopic structure. When the centralizer is installed and recovered, other tools are required to assist in the installation, which is inconvenient to operate and not suitable for long-distance cable installation.
