Abstract

The utility model relates to a protection device for the fixed cable, especially to a protection device which is suitable for the connect cable and the power cable of the electric submersible pump in the inclined well and the horizontal well in the petroleum industry. The technology scheme used is that: two group catch hoops 4 are connected with an active hinge of a cable casing 7 through a connecting pin 5 respectively, and a protected cable 6 is placed in the cable casing 7. The joint part of the two group catch hoops 4 uses hinge combination, and is fixed to a steel pipe through a bolt 2. The lateral surface around the catch hoop 4 extends a catch hoop cone 8 inward, and the inner surface of the catch hoop 4 is filled with a rubber liner 13, and the cable 6 is fixed and protected to the steel pipe 1 or the outer wall of the electric submersible pump through the catch hoop cone 8 and the rubber liner 13. The utility model can overcome the damage to the cable and oil pipe or the electric submersible pump during the using process of the inclined well and the horizontal well of the prior cable protection device, and can realize the purpose of protecting the cable.

Description

Cable protecting device

Described field: the utility model relates to a kind of protective device of attached cable, the particularly a kind of jump lead of the inclined shaft in the petroleum industry, horizontal well electric submersible pump and protective device of power cable of being applicable to.

Background technology: present domestic cable commonly used fixedly protected mode adopts metal clamps that cable guard is fixed on oil pipe or the electric submersible pump together with cable.When this mode was used in inclined shaft or horizontal well, it was fixing insecure metal clamps often to occur, causes cable bad.A kind of protective device is abroad disclosed; it is to connect two clips at the two ends of cable guard hinge; inner surface at two clips is provided with the compression sawtooth, locks by cone pin between the clip, needs the specific hydraulic instrument to finish in cone pin locking process.Should rely on the compression sawtooth of clip inwall cable to be fixed on the steel pipe by fixing protection cable unit, solve the defective that metal clamps breaks off relations easily with rigid contact of steel pipe.But because the rigid effect of compression sawtooth and steel pipe can cause damage to steel pipe or electric submersible pump surface when using in the bigger oil well of radius of curvature, the armour skin to cable constitutes damage simultaneously, has increased the potential faults of cable.Locking between the clip needs the dedicated hydraulic instrument to finish in addition, makes troubles to construction operation, has improved construction cost.

Summary of the invention: the purpose of this utility model is exactly the above-mentioned technical problem that exists at prior art, provides a kind of and can effectively realize the fixing of cable, again can be to the cable protecting device of cable and oil pipe or the effective protection of electric submersible pump realization.Realize that the technical scheme that above-mentioned purpose adopts is to existing clip protected mode; promptly be connected with cable guard 7 hinges by connecting pin 5 respectively by two groups of clips 4; protected cable 6 places in the cable guard 7; the joint portion of two groups of clips 4 is that hinge cooperates, and is fixed on the steel pipe by latch 2 grafting.On this basis, improve from the following aspects: 1, remove the compression sawtooth that is located at clip 4 inwalls, the peripheral lateral surface of the changing into clip 4 clip conical surface 8 that extended internally, dose rubber liner 13 at the inner surface of clip 4, the internal diameter of the clip conical surface 8 and rubber liner 13 is slightly less than by the external diameter of steel-fastening pipe 1.Produce strain in 13 pairs of steel pipes of the clip conical surface 8 and rubber liner or the electric submersible pump chucking process.2, offer groove 3 at two groups of clips 4 near the outer surface of joint portion, afterburning in opposite directions behind the afterburning handle insertion groove 3, behind two groups of clips, 4 chuckings, insert latch 2 hinge joint of clip 4 is locked.3, offer open slot in the bottom of latch 2, open slot can expand outwardly, and latch 2 is fixing.4, fill oil resistant rubber in the cable 6 and the joint portion of cable guard 7 and steel pipe 1, prevent the wearing and tearing of cable, and cable is fixed on electric submersible pump object or the oil pipe.5,,, can use by whole each other connection of cable guard 7 between each cable protecting device particularly in the both sides of tubing coupling according to the needs that use.The utility model has overcome the damage to cable and oil pipe or electric submersible pump in inclined shaft or horizontal well use of original cable protecting device by above improvement, effectively prevents the rotation of cable protecting device in work progress, realizes the purpose of protection cable.Simultaneously simple and practical structure makes construction operation more convenient, reduces cost of use, has improved operating efficiency.

Description of drawings: Fig. 1 is a single structure schematic diagram of the present utility model;

Fig. 2 is the side orthographic projection view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1;

Fig. 4 is a conjuncted structural representation of the present utility model.1 is oil pipe among the figure, the 2nd, latch, the 3rd, the groove that cooperates with afterburning handle, the 4th, clip, the 5th, connecting pin, the 6th, cable, the 7th, cable guard, the 8th, the clip conical surface on the clip, 9 are provided in a side of the pin hole on the clip hinge, 12 are provided in a side of the pin-and-hole that is connected on cable guard and the clip, and the 13rd, be filled in the rubber liner of clip inwall, the 14th, connect the box cupling of oil pipe.

Embodiment: embodiment 1: contrast Fig. 1,2 and Fig. 3; two groups of circular arc clips 4 are connected with cable guard 7 hinges by connecting pin 5 respectively; protected cable 6 places in the cable guard 7, and the joint portion of two groups of clips 4 is that hinge cooperates, and is fixed on the steel pipe 1 by latch 2 grafting.At the peripheral lateral surface of the clip 4 clip conical surface 8 that extended internally, the clip conical surface 8 is offered " V " shape mouth, doses rubber liner 13 at the inner surface of clip 4, and the internal diameter of the clip conical surface 8 and rubber liner 13 is slightly less than by the external diameter of steel-fastening pipe 1.Produce strain in 13 pairs of steel pipes of the clip conical surface 8 and rubber liner or the electric submersible pump chucking process.Offer groove 3 at two groups of clips 4 near the outer surface of joint portion, afterburning in opposite directions behind afterburning handle (not drawing among the figure) the insertion groove 3, behind two groups of clips, 4 chuckings, insert latch 2 hinge joint of clip 4 is locked.Open slot is offered in bottom at latch 2, and open slot can expand outwardly, and latch 2 is fixing.Fill oil resistant rubber in the cable 6 and the joint portion of cable guard 7 and steel pipe 1, prevent the wearing and tearing of cable, and cable and oil pipe or pump case are fixed.During use two groups of clips 4 are opened, after snapping in steel pipe 1, insert groove 3 with afterburning handle, afterburning in opposite directions, make the hinge joint of two groups of clips 4 fully meshing, after inserting latch 2 clip 4 is fixed on the steel pipe, because the clip conical surface 8 and liner rubber 13 elastomeric rebound effects, with latch 2 lockings.Expand outwardly with the open slot of screwdriver with latch 2 bottoms, make latch 2 can not break away from pin hole 9, the realization cable is fixed and protective effect.Embodiment 2: according to the needs that use; particularly about tubing coupling 14 (perhaps at electric submersible pump); a cable protecting device is installed respectively, is used with whole each other connection of cable guard 7 between two protective devices, cable is protected in the tubing coupling outside.The utility model can be widely used in steel pipe, electric submersible pump shell or the tubing coupling of all size, also can use the fixing and protection at various electric pole leader cables.
