Description

Underground pipe gallery cable joint protective housing

Technical Field

The invention belongs to the technical field of underground pipe gallery accessories, and particularly relates to a cable joint protective shell for an underground pipe gallery.

Background

Underground pipe gallery is used for concentrating the public tunnel of laying municipal pipelines such as electricity, communication in the city underground, and current underground pipe gallery is a both sides open-ended square structure, and interconnect forms when laying, and some special lines need the exclusive connection in the present pipe gallery, but in the pipe gallery work progress, the cable is not so long, and the centre needs to be connected, and wherein connect just sets up in the inboard triangular groove of pipe gallery, and the joint portion exposes and has the potential safety hazard outward, needs to protect the joint part. The currently commonly used cable connection is to wrap cement and tape on a cable joint, wrap a heat-shrinkable sleeve on the cable joint, add a waterproof tape and the like. However, the above-described solution is complicated to install and inconvenient to maintain. And because the particularity of underground pipe gallery has certain elasticity, sometimes the cable joint can break.

In order to achieve the purpose, the technical scheme of the invention is as follows:

the utility model provides an underground pipe gallery cable joint protective housing, includes casing and junction block, the longitudinal section of casing is right triangle, and it has the operation mouth to open on its inclined plane, and the casing both sides are equipped with the cable import, the junction block sets up inside the casing, the junction block includes insulating casing, two wiring pipes and a power transmission pipe, two wiring pipe parallel arrangement are in insulating casing, two wiring pipes of power transmission union coupling, the junction block both sides are equipped with the increase piece that the position is staggered, also be equipped with the wiring pipe in the increase piece, all the wiring pipe outsides are equipped with the locking bolt, the operation mouth edge is equipped with the recess, is equipped with the apron on the operation mouth, the apron top passes through hinge connection with the casing, and the casing below is equipped with spring shackle.

As an improvement of the invention, the inner wall of the shell is provided with an insulating layer.

As an improvement of the invention, the patch tubes in the plenum are tapered, the farther away the patch tubes are, the smaller the patch tubes are.

As a modification of the invention, the edge of the cover plate is provided with a sealing strip.

As an improvement of the invention, a rubber pad is arranged at the cable inlet.

As an improvement of the invention, the added blocks on both sides of the wiring block are staggered from left to right and from top to bottom.

The invention has the beneficial effects that:

according to the cable joint protective shell for the underground pipe gallery, the cable joint is stably connected in the shell, and the cable joint protective shell is safe, reliable, convenient to operate and good in waterproof performance.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic diagram of a junction block and an increasing block according to the present invention.

List of reference numerals:

1. the cable comprises a shell, 2, a wiring block, 3, an operation opening, 4, a cable inlet, 5, an insulating shell, 6, a wiring pipe, 7, a power transmission pipe, 8, an additional block, 9, a wiring pipe in the additional block, 10, a locking bolt, 11, a groove, 12, a cover plate, 13, a hinge, 14, a spring lock catch, 15, a sealing strip, 16, a rubber pad, 17 and a cable.

Detailed Description

The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in the figures, the cable joint protective housing for the underground pipe gallery comprises a housing 1 and a wiring block 2, wherein the longitudinal section of the housing 1 is a right triangle, an operation opening 3 is formed in the inclined plane of the housing 1, cable inlets 4 are formed in two sides of the housing 1, the wiring block is arranged in the housing and comprises an insulating shell 5, two wiring pipes 6 and a power transmission pipe 7, the two wiring pipes 6 are arranged in the insulating shell 5 in parallel, the power transmission pipe 7 is connected with the two wiring pipes 6, additional blocks 8 with staggered positions are arranged on two sides of the wiring block, wiring pipes 9 are also arranged in the additional blocks, locking bolts 10 are arranged on the outer sides of all the wiring pipes, a groove 11 is formed in the edge of the operation opening 3, a cover plate 12 is arranged on the operation opening, the upper portion of the cover plate 12 is connected with the housing 1 through a hinge 13, and a spring lock 14 is arranged below.
