Anti-falling cable branch box

Abstract

The invention provides an anti-falling cable branch box. The anti-falling cable branch box comprises a branch box body, first fixing holes, an air collecting cover, air inlet holes, limiting grooves,a movable cover, air storage cavities, air inlet pipes, tapping sleeve heads, first shunting pipes, second shunting pipes, air inducing grooves, limiting chucks, reinforcing rods, counterweight chassises, second fixing holes, bolt holes, extruding plates, extruding blocks and counterweight blocks. The first fixing holes penetrate the two sides of the upper middle portion of the branch box body. When the extruding plates are pressed against the counterweight blocks, the inverted splayed extruding blocks exert a vertical tension on the counterweight blocks. The contact area between the extrudingblocks and the counterweight blocks can be increased when the extruding blocks are opened up and down. The stability of the four sides of the counterweight blocks is further enhanced. The overall tilting prevention performance of the branch box body, the counterweight chassises and the counterweight blocks which are connected by means of the reinforcing rods can be improved. With the cooperationof an original cement pier, a set of tilting prevention structures are additionally arranged at the bottom of the branch box body. Therefore, the usage efficiency of the coastal area branch box is improved.

Description

technical field [0001] The invention belongs to the technical field of cable branch boxes, and more specifically relates to an anti-fall cable branch box. Background technique [0002] Power cables are mainly used to transmit and distribute electric energy from power plants, and also serve as connection tools between various electrical equipment. It is necessary to use branch boxes to arrange the cables separately to avoid cable entanglement, so as to achieve high power supply reliability. It is relatively safe for people, and has the advantages of simple operation, no external influence, and small maintenance workload. However, when the branch box is affected by strong wind, the installation part at the bottom of the branch box is easy to cause loosening. [0003] In order to reduce the problem that the branch box is affected by strong winds, concrete is usually added to the branch box again to form a reinforced cement pier at the bottom of the branch box to solve the probl...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides an anti-falling cable branch box to solve the problem that after the existing typhoon blows, the reinforced cement pier at the bottom of the branch box will loosen due to the strong blowing of the typhoon, causing the branch box to be easily broken. Dumping occurs, which will bring some troublesome problems during the power supply process
