Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to an explosion-proof power distribution cabinet. Background Art

[0002] The electric cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. When the traditional distribution cabinet is in use, because there are many power control components in the distribution cabinet, it will generate very high heat when it is powered on. When the heat inside the distribution cabinet is high and the components are aged and damaged, flames may be generated, causing combustion inside the distribution cabinet, and then the flames will spread through the internal components of the distribution cabinet, causing fires or electrical explosions. Therefore, the distribution cabinet will open a heat dissipation window for heat dissipation, but it still cannot completely avoid fires caused by aging of internal components, so it is necessary to take precautions against this situation.

[0003] The existing distribution cabinet only changes the material of the distribution cabinet to explosion-proof material, and does not handle it in case of fire. While increasing the risk of explosion, all the devices in the distribution cabinet will be burned in the event of fire, causing huge economic losses. Therefore, an explosion-proof distribution cabinet is needed. Utility Model Content

[0004] The purpose of the utility model is to provide an explosion-proof power distribution cabinet, which solves the problems raised in the background technology.

[0005] An embodiment of the present application provides an explosion-proof distribution cabinet, including a device body, a door panel is provided on the device body, a handle is provided on the door panel, a pressure relief box is fixedly installed on the side wall of the device body, a connecting rod is provided on the pressure relief box, and a horizontal plate is fixedly installed on the lower end of the connecting rod passing through the device body.

[0006] In this technical solution, when a fire breaks out in the main body of the device, a large amount of gas will be generated, which makes the internal air pressure relatively high. The gas will enter the pressure relief box, squeezing the movable plate to move upward, thereby driving the connecting rod and the baffle to move upward. When the baffle moves to the top of the pressure relief pipe, the gas can be discharged through the pressure relief pipe, thereby reducing the air pressure in the main body of the device to prevent explosion. When the connecting rod moves upward, it will drive the horizontal plate to move upward. When the horizontal plate moves upward, it will drive the first rotating rod and the second rotating rod to rotate, thereby moving the sealing plate. The vent can be sealed by the sealing plate. After burning for a period of time, the air in the distribution cabinet will be consumed, which will play a role of automatic fire extinguishing. At the same time, when the baffle moves, it will drive the cleaning plate to move, thereby cleaning the vent. When the baffle moves to a certain position, the sensor will send a signal to the central computer to remind the staff of the fire and deal with it in time.

The gas will enter the pressure relief box, squeezing the movable plate to move upward, thereby driving the connecting rod and the baffle to move upward. When the baffle moves to the top of the pressure relief pipe, the gas can be discharged through the pressure relief pipe, thereby reducing the air pressure in the main body of the device and preventing explosion.

[0011] Optionally, a cleaning plate is fixedly mounted on the side of the baffle.

[0012] By adopting the above technical solution, when the baffle moves, it will drive the cleaning plate to move, thereby cleaning the vent.

[0013] Optionally, a vent is provided on the device body, and the cleaning plate is against the vent.
