Abstract
An underground cable fixed protection device relates to a fixed protection device, and solves the problem that the existing underground cable fixed protection device has bad protection effect, is easy to drop off and to rupture cable. The two sides of a protecting grill (5-1) curl towards each other and form a curl cavity (5-2) respectively; the two terminals of the protecting grill (5-1) are connected with a fixed strip connecting piece (5-5) by an excessive tilt piece (5-4) into an integrity; each curl cavity (5-2) is internally provided with a thin steel bar piece (5-3) respectively, and the two fixed strip connecting pieces (5-5) are provided with slots (5-5-1); the two fixed strips (3) pass through the slot (5-5-1) respectively, and the two terminals of the fixed strip (3) are connected with each other by a corresponding hook (6). The invention realizes cable rapid fixation and effective protection, and has the advantages of simple installation, good reliability and good effect in fixedly protecting the cable.
Description
Technical field
The present invention relates to a kind of fixed-guard, be specifically related to a kind of fixed-guard that is used for the petroleum production downhole cable.
Background technique
Down-hole oil production equipment and data acquisition equipment generally adopt cable power supply or transmission signal.What the downhole cable fixing device solved is the fixing and protection question of various cables in the oil well.At present, the power supply and the data transmission of underground equipment adopt cable more, and cable is in lax free state between oil pipe and sleeve pipe, and in two-section tubing coupling place because external diameter increases, elastic cable paper is easy to be caused damage by oil-pipe external wall and internal surface of sleeve pipe extruding.If do not take fixing and protective measures, because cable is longer under the oil well, oil well rig plays impact in the process of assembling, the phenomenon of colliding with is comparatively serious, and the oil well circumstance complication, easily cable is caused in various degree damage, thus the reliability that influence power supply and signal transmit.Existing downhole cable protective equipment protection effect is bad, come off easily, easily causes the fracture of cable, causes damage to the oil field.As Chinese patent notice of authorization number for CN2911361Y, notice of authorization day be June 13 in 2007 day, be called " the down-hole oil-submersible cable fixing device that has protective housing ", a kind of down-hole oil-submersible cable fixing device is disclosed, not good to the cable protection effect.Because its structure increases circumferential radius, collide with sleeve pipe easily and cause and come off.And its on-the-spot connection is complicated, greatly reduces the working efficiency in oil field.
Summary of the invention
The present invention for solve existing downhole cable fixing device exist protection effect bad, come off easily, easily cause the problem of cable fracture, and then a kind of downhole cable fixation and protection device be provided.
The technological scheme that the present invention solves the problems of the technologies described above employing is: fixed-guard of the present invention is by the protective housing assembly, two fixed strips and two buckles are formed, described protective housing assembly is by boot main body, two fine steel rib spares, two over-tilting spares, two fixed strip links are formed, the dual-side of described boot main body curls in opposite directions and forms the chamber of curling respectively, the two ends of described boot main body respectively link into an integrated entity by an over-tilting spare and fixed strip link, in described each curling chamber a fine steel rib spare is housed respectively, is equipped with notch on described two fixed strip links; Described two fixed strips pass notch respectively, and the two ends of each fixed strip connect by corresponding buckle.
The invention has the beneficial effects as follows: use of the present invention has realized the fast fixing and effectively protection of cable, has simple, good reliability, cable not easy-rupturing, the effective advantage of fixed protection cable are installed.The present invention especially is fit to the fixed protection of the cable (as cable, optical cable etc.) of tubing coupling place.

Embodiment
Embodiment one: shown in Fig. 1～11, the described fixed-guard of present embodiment is by protective housing assembly 5, two fixed strips 3 and two buckles 6 are formed, described protective housing assembly 5 is by boot main body 5-1, two fine steel rib spare 5-3, two over-tilting spare 5-4, two fixed strip link 5-5 form, the dual-side of described boot main body 5-1 curls in opposite directions and forms the chamber 5-2 that curls respectively, the two ends of described boot main body 5-1 respectively link into an integrated entity by an over-tilting spare 5-4 and fixed strip link 5-5, in described each curling chamber 5-2 a fine steel rib spare 5-3 is housed respectively, is equipped with notch 5-5-1 on described two fixed strip link 5-5; Described two fixed strips 3 pass notch 5-5-1 respectively, and the two ends of each fixed strip 3 connect by corresponding buckle 6.
The described protective housing assembly 5 of present embodiment is to be cut out, curl, be stamped to form by iron sheet; the two ends of protective housing assembly 5 dash notch 5-5-1; two fine steel rib spare 5-3 that clamp in two curling chamber 5-2 play the protection supporting effect, are cable cavity volume 5-6 between two fine steel rib spare 5-3.Described boot main body 5-1, two over-tilting spare 5-4 and two fixed strip link 5-5 are one, are washed into by an iron plate.
Embodiment two: shown in Fig. 1～11, the described buckle 6 of present embodiment is overlapped by the two ends that strip tape is curled into cavity and strip tape.Described buckle 6 has advantage of convenient mounting.Other composition and annexation are identical with embodiment one.
Embodiment three: shown in Fig. 1～11, an end of the described fixed strip 3 of present embodiment is from being attached to the two ends overlapping of buckle 6 after the cavity of described buckle 6 passes and bends, and the other end of described fixed strip 3 passes from the cavity of buckle 6.In use, the other end of outside tractive fixed strip 3 after waiting to compress, is cut remainder gradually, and under the effect of pulling force, the part of turning up of fixed strip 3 closely contacts and compresses with buckle 6 laps, and self-locking mutually makes fixed strip 3 be difficult for unclamping and comes off.Other composition and annexation are identical with embodiment two.
Working principle:
When implementing fixing to cable and protecting, at first cable 4 is tightened and be placed on along its length in the cable cavity volume 5-6, make protective housing assembly 5 be attached to tubing coupling 2 (tubing coupling 2 is used to connect two oil pipes 1) outer side wall then, make described cable 4 between tubing coupling 2 and protective housing assembly 5; Two fixed strips 3 are passed notch 5-5-1 respectively; fixed strip 3 is around the outer side wall of oil pipe 1; oil pipe 1 and cable 4 are bundled; the two ends of each fixed strip 3 connect by corresponding buckle 6; so just realized cable 4 is fixed on the oil pipe 1 that has tubing coupling 2; because cable cavity volume 5-6 is arranged in the protective housing assembly 5, but better protection cable 4 avoids cable 4 to cause damage because of extruding.
