Abstract

The utility model provides a duplex cable protector which comprises an intermediate connecting body and clips which are connected with both ends of the intermediate connecting body. A rubber body is arranged on the inner wall of each clip. Each clip is composed of two semi-circular arc clamping pieces, wherein hinges at two ends of the semi-circular arc clamping pieces are folded. Each clamping piece comprises a connecting part in the middle and fixing claws on both ends. Upper and lower end faces of each connecting part are provided with arc gaps. Compared with the prior art, the duplex cable protector provided by the utility model has the advantages of simple structure, reasonable design and small occupied space, and is especially suitable for the protection and the lowering of an electric pump cable and a hydraulic control pipeline in a submersible electric pump production oil-water well. The safety factor of well descending can be greatly improved, and accident hidden dangers are reduced.

Description

Duplex cable protector

Technical field

The utility model relates to a kind of protective device for attached cable on pipeline, liquid controling pipe line, is specially adapted to the oil-water well of submersible electric pump production to the duplex cable protector of electric-pump cable and liquid controling pipe line.

Background technology

In the oil well that lower oil-immersed pump is produced, the liquid controling pipe line that the cable of power is provided and is used for data acquisition for electric pump all outside oil pipe with the electric pump lower going-into-well.Due to the depth of setting of submersible electric pump generally all more than 1000 meters; be that cable and liquid controling pipe line length in well also need to be more than 1000; therefore need to protect the cable of electric pump, to prevent in removing the process of electric pump pipe column because bad cable and liquid controling pipe line are squeezed in the collision between oil pipe and sleeve pipe.Need with special electric pump cable protection device, cable to be bundled on oil pipe for this reason; on the one hand cable and oil pipe are close together; avoid cable to break because of the self gravitation effect; on the other hand due to the external diameter of protector than the large effect that can play righting of oil pipe; avoid the collision between tubing and casing, also just can avoid cable to be squeezed.No matter be at straight well or in inclined shaft, the collar segments of oil pipe is all the keypoint part of cable protection.Because the box cupling position of oil pipe is slightly more a lot of than oil pipe body, the cable collision injury that the most easily is squeezed at this position.At present electric pump cable protection device commonly used mainly is divided into for the duplex protector at tubing coupling position and is used in simply connected protector on the oil pipe body, such as patent 200520083263.X, it discloses a kind of simply connected protector, it is that clamp by two semicircular arcs is to being combined into, wherein the structure of upper and lower semicircle is similar, wherein upper semi-circle clamp two ends for be provided with fixed claw, the centre is provided with connecting portion, and connecting portion is the straight flange structure, and the lower semi-circular clamp is equipped with fixed claw on the whole; In like manner present duplex protector namely is equivalent to two simply connected protectors are connected (referring to Fig. 1) by intermediate connector; its drawback of above-mentioned design is; this design has caused the volume of protector integral body larger; when being lowered to sleeve pipe with oil pipe; if when on casing wall, foreign material being arranged; protector is easy to be blocked and blocks, thereby affects transferring of cable.

The utility model content

The purpose of this utility model is exactly the defective that exists for prior art, and a kind of little duplex cable protector that takes up room is provided, easy jammed defective when it can solve existing electric cable protector and is lowered to sleeve pipe.

The concrete technical scheme of the utility model is: comprise the clamp that intermediate connector and two ends thereof connect, the clamp inwall is provided with rubber bodies; Described clamp by the fastener of two semicircular arcs the hinge by two ends to being combined into, the connecting portion in the middle of described each fastener comprises and the fixed claw at two ends, described connecting portion outside end face is provided with the breach of arc.

Such scheme is more preferably:

Described two mutual two involutory fastener one ends are by the steady pin chain connection, and the other end is by the latch chain connection; Wherein steady pin one end is as stiff end, and latch one end by insertion and the taking-up of latch, is completed opening and closure of clamp integral body as movable end.

Described fixed claw is assembled the formation cone structure to the inside, so that fixed claw blocks oil pipe.

The utility model compared with prior art; simple in structure, reasonable in design, take up room little; be specially adapted to submersible electric pump produce oil electric-pump cable and liquid controling pipe line in well protection and transfer, it can improve the coefficient of safety of going into the well greatly, reduces accident potential.

Description of drawings

Fig. 2 is the structural representation after the fastener of a kind of embodiment of the present utility model launches;

In figure: 1, connecting portion, 2, fixed claw, 3, otic placode, 4, intermediate connector.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

Referring to Fig. 2, a kind of duplex cable protector, comprise the clamp that intermediate connector 4 and two ends thereof connect, the clamp inwall is provided with rubber bodies, clamp by the fastener of two semicircular arcs to being combined into (state of Fig. 2 for fastener being stretched after launching), the connecting portion 1 in the middle of each fastener comprises and the fixed claw 2 at two ends, the outside end face of connecting portion 1 is provided with the breach of arc, fixed claw 2 is assembled the formation cone structure to the inside, so that fixed claw blocks oil pipe; One end of each fastener is provided with otic placode 3, an other end and is provided with two otic placodes 3, during use with the otic placode 3 of two mutual involutory fastener one ends by the steady pin chain connection, other end otic placode is by the latch chain connection; Wherein steady pin one end is as stiff end, and latch one end by insertion and the taking-up of latch, is completed opening and closure of clamp integral body as movable end.

The inner groovy that many different sizes are arranged at the rubber part of protector can snap in the underground cables such as electric-pump cable, liquid controling pipe line, capillary line.In work progress; two fasteners of clamp are closed up after oil pipe and various cable; the clamp at two ends is partly embraced on the oil pipe in the outside, box cupling two ends; intermediate connector blocks box cupling; the cable and the various pipeline that need protection are placed in the groove of rubber part different size; with tensioning clamp, clamp is strained, then latch is inserted pin clamp.This moment the clamp outer rim fixed claw will with the oil-pipe external wall close contact, form wheel chair access slope, avoided being hampered in the process of going into the well.

Only need upwards latch to be taken off once the top bottom latch when tripping out.The shell of protector has adopted the processing of 3mm steel plate, and after tripping out, as long as without being out of shape and damaging, can reuse after changing the inner rubber pad, steady pin can reuse equally.

For those skilled in the art, under the prerequisite that does not break away from the utility model principle, might be to concrete size, perhaps partial structurtes are made some improvements and modifications, and these improvements and modifications also should be considered as protection range of the present utility model.
