Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of distribution box, specifically a distribution box for distribution network. BACKGROUND

[0002] The distribution box is a common electrical equipment, and most of the distribution boxes refer to the device formed by assembling switchgear, measuring instruments, protective appliances and the like in a closed or semi-closed metal cabinet according to electrical wiring requirements. The distribution box has the advantages of high safety protection level, simple installation and no site limitation, and can be used as a control center for reasonably distributing electric energy of various components in a power supply line, and the opening and closing operation of the circuit by relevant operating personnel can be facilitated through the distribution box.

[0003] However, since a large number of components are arranged in the distribution box and the components are in a relatively closed space, the components will generate a large amount of heat during operation, and the excessive heat will affect the use performance and safety performance of the distribution box. In addition, the cables of the large number of components are randomly placed, which will cause the cables to be entangled and gathered, and this situation will also cause the local temperature of the distribution box to be too high, thereby affecting heat dissipation. At present, the common heat dissipation method of the distribution box is to install a fan on the top of the distribution box for heat dissipation. This heat dissipation method not only consumes power, but also needs to be regularly maintained. If the fan is short-circuited, it will most likely cause the distribution box to malfunction. In addition, the common distribution box cannot adapt to uneven walls. SUMMARY

[0004] To solve the problems in the background art, the utility model provides a distribution box for a distribution network to solve the problems of high heat dissipation cost and inability to adapt to uneven walls.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a distribution box for a distribution network, characterized by comprising a box body, a door plate and a fixing frame, the box body is composed of an upper plate, a lower plate and a bottom plate, the upper plate and the lower plate are embedded on the upper and lower sides of the bottom plate, vertical airflow channels are arranged on the left and right sides of the inside of the bottom plate, the vertical airflow channels abut against the bottom plate and are hollow inside, the bottom plate is connected with the door plate through a hinge sleeve and a hinge seat, the fixing frame is composed of a fixed sheet metal, a universal joint, a mechanical arm and a fixed surface, and the fixing frame is installed on the rear side of the bottom plate through the fixed sheet metal.

[0015] In the utility model, the bottom plate is provided with a heat pipe, and the bottom plate is provided with a heat dissipation hole corresponding to the vertical air flow channel, the heat pipe is a technology for transferring heat by evaporation and condensation, and is composed of a pipe shell, a wick and an end cover, and is filled with appropriate liquid, when one end of the heat pipe is heated, the liquid rapidly evaporates, the steam flows to the other end and releases heat, and the liquid condenses into liquid again and flows back to the evaporation section along the porous material, forming a closed cycle, and transferring heat from one end to the other end, and part of the heat pipe is located outside the distribution box, and the heat dissipation effect is better, because the accessories in the distribution box continuously generate heat when the distribution box is used, the hot air moves upward and flows to the low pressure place, the heat dissipation hole can make the external space communicate with the vertical air flow channel, so that the efficiency of the hot air flowing to the vertical air flow channel is higher, and the heat dissipation effect is better.

[0016] In this utility model, the fixing frame consists of a fixed sheet metal, a universal joint, a robotic arm, and a fixing surface. The fixing frame is installed on the back of the base plate through the fixed sheet metal, and the universal joint is set on the fixed sheet metal. The fixing surface is connected to the universal joint through the robotic arm. When users encounter different wall surfaces, such as inclined walls, the fixing frame can adapt to these unbalanced walls. It can also adjust the position of the distribution box according to the user's own needs, so that the tilt angle of the distribution box can be adjusted, which greatly increases the speed of installation and disassembly of the distribution box, thereby reducing the time required for debugging the distribution box.

[0017] In this utility model, a waterproof eaves is provided on the upper side of the outer side of the upper plate, and baffles are provided on both sides of the waterproof eaves. When thunderstorms occur, the waterproof eaves and baffles can prevent rainwater or other debris from falling into the distribution box, causing short circuits or other adverse effects in the distribution box, thus greatly improving the safety of the distribution box and reducing the maintenance cost of the distribution box.

[0018] The hinge sleeve and hinge seat described in this utility model are fixed by a pin. When maintenance personnel want to disassemble the door panel, they only need to pull out the pin to successfully disassemble it. If maintenance personnel only want to inspect the cabinet, they can pull out the pin a little to lock the door panel and prevent the door panel from pushing back naturally, which helps maintenance personnel to carry out maintenance work more conveniently.
