Description

Underground cable protector

Technical field

The utility model belongs to oil field well cable protecting device field more particularly to a kind of underground cable protector.

Background technique

In the work progress of oil field, it is sometimes desirable to building-out cable and be transferred cable together with tubing string on the outside of oil pipe column To well, cable damages in operation process in order to prevent, it usually needs cable protecting device is arranged at tubing coupling, so And the structure of the electric cable protector in downstream is not reasonable, has to the protecting effect of cable to be hoisted.

Summary of the invention

The utility model provides a kind of underground cable protector, to solve the problems mentioned in the above background technology.

The technical problem solved by the utility model is implemented by the following technical solutions:

The utility model provides a kind of underground cable protector, including substrate and clamp arm, and substrate is strip structure, and clamp arm is total There are two groups, two groups of clamp arm are respectively hinged at the both ends of substrate, are total in every group of clamp arm there are two clamp arm, the free end of two clamp arm connects After being connected together, two that the underground cable protector is encircled in the outside of oil pipe column, every group of clamp arm can be made The free end of a clamp arm is connected by bolt, and the groove for accommodating cable, the side of groove are provided on the inside of the substrate It is provided with the gap for accommodating box cupling, gap is located at the middle and upper part of substrate, and the edge of the clamp arm is provided with zigzag knot Structure.

The head of the bolt is provided with the circular hole that diameter is not less than 8mm, referred to as impact opening.It is arranged in the clamp arm There is the mounting hole for installing rubber pad.

The utility model has the following beneficial effects: the utility model is provided with the groove that section is U-shaped, installation on substrate Afterwards, the side wall of groove can be stablely supported on the outside of oil pipe and box cupling, improve the resistance to compression on the outside of substrate and impact resistance, To carry out relatively reliable protection to cable；The setting of gap is stuck in the utility model on box cupling securely, thorough Bottom prevents the utility model vibration on tubing string, meanwhile, clamp arm the utility model occur up and down vibration movement tendency when by Power situation will not change, therefore can effectively avoid the damage of the tie point in clamp arm.

Specific embodiment

The utility model is described further below in conjunction with attached drawing:

The present embodiment includes substrate 1 and clamp arm 2, and substrate 1 is strip structure, and clamp arm 2 shares two groups, and two groups of clamp arm 2 are distinguished It is hinged on the both ends of substrate 1, there are two clamp arm 2 altogether in every group of clamp arm 2, after the free end of two clamp arm 2 links together, can make The underground cable protector is encircled in the outside of oil pipe column.The above are universal architectures in the prior art, herein no longer It repeats.

The free end of two clamp arm 2 in every group of clamp arm 2 is connected by bolt 6, is arranged on the inside of the substrate 1 There is the groove for accommodating cable.The utility model is provided with the groove that section is U-shaped, after installation, the side of groove on substrate 1 Wall can be stablely supported on the outside of oil pipe and box cupling, resistance to compression and the impact resistance in 1 outside of substrate be improved, thus to cable Relatively reliable protection is carried out.

The side of groove is provided with the gap 4 for accommodating box cupling, and the setting of gap 4 allows the utility model securely It is stuck on box cupling, thoroughly prevents the utility model vibration on tubing string, meanwhile, gap 4 can guarantee that clamp arm 2 is sent out in the utility model Stress condition will not change when the raw movement tendency of vibration up and down, therefore can effectively avoid the damage of the tie point in clamp arm 2.

Gap 4 is located at the middle and upper part of substrate 1, i.e. the substrate 1 that 1 length of substrate of 4 downside of gap is greater than 4 upside of gap is long Degree, in this way the reason of setting are: compared to a well is played, cable is easier to be impacted and collided with when going into the well, and uses above-mentioned Structure can carry out stressing to protect to the cable on the downside of box cupling, so as to improve protecting effect.

The edge of the clamp arm 2 is provided with laciniation, and the gap of sawtooth was used for line.

The head of the bolt 6 is provided with the circular hole that diameter is not less than 8mm, referred to as impact opening 5, by using bottle opener and The tools such as hammer exert a force to impact opening 5, can quickly play out bolt 6.

The mounting hole 3 for installing rubber pad is provided in the clamp arm 2, by installing rubber pad on the inside of clamp arm 2 Cable can further be protected.
