Abstract
The utility model discloses a single-link self-locking-type cable protection device, and relates to cable protection devices. The single-link self-locking-type cable protection device solves the problems that cable clamps for fixing down-hole cables of an existing electric submersible pump well are poor in cable protection effect, large in construction strength and not capable of being used in a repeated mode, and cost is increased due to the fact that mating construction tools are easily damaged. The single-link self-locking-type cable protection device comprises a body, a connecting body, a pressing lock cap, a hanging ring and a protective layer. One end of the body is connected with one end of the connecting body in a rotating mode. The other end of the connecting body is connected with the hanging ring in a rotating mode. The pressing lock cap is connected with one end of the hanging ring in a rotating mode. A hole is formed in the hanging ring. A hook matched with the hole of the hanging ring is arranged at the other end of the body. The hanging ring is movably connected with the body through the hook. The protective layer is arranged on the inner wall of the body. The single-link self-locking-type cable protection device is used for protection of the down-hole cables.
Description
Technical field
The utility model relates to a kind of cable protecting device.
Background technique
The oilfield submersible pump well adopts oil-submersible cable as the well dynamic cable usually at present, the widespread usage strain relief clamp is as the instrument that cable is fixed on the oil pipe when going into the well, the steps include: earlier strain relief clamp to be walked around oil pipe, one end passes the clamp kink, cable is fixed on the oil pipe clamp tension with the tension pincers, the recycling locking pliers kills kink, at last the clamp redundance is pinched folding, finishes installation.This means of fixation needs two operation workmans ability complete operations when mounted at least; and it is uneven that tightness is installed; tension damages cable easily; it is bad to cross loose fixed effect, and the back of going into the well easily takes place to slide to scurry the cable protection weak effect; not reproducible use; the matching operation instrument is also fragile, has caused bigger cost waste, and labor strength is big simultaneously, efficiency of construction is low.
The model utility content
The purpose of this utility model provides a kind of simply connected self-locking cable protecting device; fixing big with strain relief clamp cable protection weak effect, construction intensity to solve present submerged electric oil pump well downhole cable, the fragile problem that causes cost to increase of not reproducible use and matching operation instrument.
The utility model is to solve the problems of the technologies described above the technological scheme of taking to be: described device comprises main body, connecting body, pressure lock nut, link and protective layer; one end of main body and connecting body one end are rotationally connected; the other end and the link of connecting body are rotationally connected; press an end of lock nut and link to be rotationally connected; have the hole on the link; the other end of main body is provided with the hook that the hole with link is complementary, and link and main body flexibly connect by hook, and protective layer is located on the inwall of main body.
The utlity model has following beneficial effect: the utility model adopts main body that cable grip is pressed on the oil pipe, and the inwall of main body is provided with protective layer, and the principle that increases frictional force overcomes that the easy slide down of former strain relief clamp is scurried, the problem of cable play.Utilize hook to connect when installing and dismantling, only need get final product complete operation by an operating worker, labor intensity significantly reduces, and efficient improves.The utlity model has quick and easy for installationly, the cable protection performance is good, and the recycling rate of waterused advantages of higher does not need extra kit, and the convenient working construction reduces potential safety hazard.
