Outdoor cable branch box

Abstract

The invention relates to the technical field of cable branch boxes, and particularly discloses an outdoor cable branch box. The outdoor cable branch box comprises a box body; a box opening is formed in the front side face of the box body; a box door is rotatably connected to the interior of the box opening; a conical winding roller is rotatably connected to the interior of the box body; a fan-shaped water retaining fabric is wound around the conical winding roller; a hydraulic oil tank is arranged at the front end of the bottom wall of an inner cavity of the box body; a plurality of partitionplates are arranged in the hydraulic oil tank at equal intervals; the interior of the hydraulic oil tank is divided into a plurality of independent hydraulic oil cavities by the partition plates; theupper surface of each hydraulic oil cavity is connected with a vertical piston cylinder; the piston cylinders are communicated with the corresponding hydraulic oil cavities. According to the outdoor cable branch box disclosed by the invention, a whole hydraulic pushing device and a circuit device mounting base are independently arranged; the structure of the outdoor cable branch box is novel; thesafety performance of the outdoor cable branch box during maintenance is higher; the design of the whole fan-shaped water retaining fabric is novel, and particularly, the waterproof effect of the fan-shaped water retaining fabric on rush repair in rainy days is very excellent.

Description

technical field [0001] The invention relates to the technical field of cable branch boxes, and specifically discloses an outdoor cable branch box. Background technique [0002] The cable branch box is a kind of distribution box that mainly divides or transfers cables, and mainly plays the role of cable branching and cable switching. As the name implies, the outdoor cable branch box is a cable branch box installed outdoors, and the outdoor cable branch box is mainly fixed on the ground or on a pole during installation. [0003] At present, all cable branch boxes on the market will fix all wiring switches, circuit breakers and other circuit components on the mounting board deep inside the box when tapping or switching the circuit. When other circuits are normally energized, the operator needs to put his body into the inside of the box to operate during the maintenance process, which not only makes the whole circuit maintenance process more troublesome, but also has a greater ...

AI Technical Summary

Problems solved by technology

[0003] At present, all cable branch boxes on the market will fix all wiring switches, circuit breakers and other circuit components on the mounting board deep inside the box when tapping or switching the circuit. When the other circuits are normally energized, the operator needs to put his body into the box to operate during the maintenance process, which not only makes the whole circuit maintenance process more troublesome, but also has a greater risk of electric shock

Especially when working in rainy days, it not only increases the risk of electric shock for the operator, but also rainwater easily falls into the box when the operator opens the door on the box, causing damage to other circuit components

[0004] For example, the patent No. CN108574254A discloses a cable branch box, which includes a box body, a bottom plate, a mounting plate, an incoming line bar, an incoming line circuit breaker, a busbar, an outgoing line breaker, an outgoing line bar, and a box door. The bottom of the body is provided with a bottom plate; the inside of the box is provided with a mounting plate, and the front and back of the mounting plate are equipped with incoming line bars, busbar bars and outgoing line bars, and the incoming line bars are installed with incoming lines A circuit breaker, the outlet circuit breaker is installed on the outlet row; the front and back of the box are equipped with doors; the cable branch box disclosed by the invention is a common type in the market, and the circuit failure in the branch box When maintenance is required, the operator still needs to put part of his body into the box, which poses a risk of electric shock; in addition, when the power distribution cabinet is repaired in rainy days, it is easy to enter a large amount of rainwater, which not only increases the risk of electric shock when the operator rushes to repair , and it is easy to cause internal circuit failure due to the infiltration of rainwater
