Novel power distribution box with convenience in maintenance

Abstract

The invention discloses a novel power distribution box with convenience in maintenance. The novel power distribution box comprises a power distribution box body. Fixing plates are arranged inside the power distribution box body, an end of each fixing plate is rotationally connected with the inner wall of one side of the power distribution box body by a rotary shaft, the rotary shaft is slidably connected with slide grooves by sliders, the slide grooves are formed in the inner wall of the side of the power distribution box body, heat dissipation holes are formed in the side wall of the other side of the power distribution box body, closing sheets are arranged inside the heat dissipation holes, an end of each closing sheet is connected with a chain by a gear disc in a meshing manner, an end of each gear disc is in transmission connection with a motor by a transmission shaft, and a rainwater sensor is arranged on the top of the power distribution box body. The novel power distribution box has the advantages that the three fixing plates are arranged inside the novel power distribution box, can rotate along the rotary shaft and can outwardly slide along the slide grooves, accordingly, the mounting flexibility of power equipment can be improved, and the novel power distribution box can bring convenience for mounting the power equipment and detaching and maintaining the power equipment in late periods.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to a novel power distribution box which is convenient for maintenance. Background technique [0002] Distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment, can connect with manual or automatic switch during normal operation. Open or break the circuit, cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal working conditions. [0003] The interior of the distribution box is usually equipped with a variety of power equipment. Th...

Problems solved by technology

[0003] The interior of the distribution box is usually equipped with a variety of power equipment. The existing distribution box is very inconvenient in the installation, disassembly and maintenance of the power equipment, and there are often cooling holes on the side wall of the distribution box. In rainy weather, rainwater It can easily enter the inside of the distribution box, causing a short circuit to the power equipment and causing an accident
