Fire extinguishing device for power distribution cabinet

Abstract

The invention belongs to the field of fire extinguishing equipment and relates to a fire extinguishing device for a power distribution cabinet. The cabinet comprises a cabinet body; a plurality of outer air holes which are uniformly distributed are formed in the side wall of the cabinet body; the inner side wall of the cabinet body is connected with an isolation plate in a sliding manner; a plurality of uniformly distributed inner air holes are formed in the isolation plate; the plurality of outer air holes are communicated with the plurality of inner air holes one by one; the inner top surface of the cabinet body is fixedly connected with a heat conduction box; a rotating shaft which is horizontally arranged is rotationally connected into the heat conduction box; a driving wheel and two driving gears are fixedly arranged on the rotating shaft in a sleeving mode; the two driving gears are arranged on the two sides of the driving wheel respectively; two vertically-arranged rotating rodsare arranged in the heat conduction box; and crown gears connected with the driving gears in an engaged mode are fixedly connected to the upper ends of the two rotating rods. When a fire occurs in the power distribution cabinet, an extrusion plate in a rotating box can continuously move up and down when the driving wheel rotates, so that a fire extinguishing solution in a lower cavity can be sprayed into the cabinet body to extinguish the fire.

Description

technical field [0001] The invention belongs to the field of fire extinguishing equipment, in particular to a fire extinguishing device for a power distribution cabinet. Background technique [0002] The power distribution cabinet is the final equipment of the power distribution system. It is the general name of the motor control center. It distributes the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load, and plays the role of regulating multiple circuits. [0003] There are a large number of transmission circuits and electronic components inside the power distribution cabinet. When they are in working condition, high heat will be generated in the power distribution cabinet. Long-term high temperature will affect the service life of electronic components in the power distribution cabinet, especially in the In summer, the high temperature inside the power distribution cabinet is more likely to cause a fire. Most of the t...

Problems solved by technology

[0003] There are a large number of transmission circuits and electronic components inside the power distribution cabinet. When they are in working condition, high heat will be generated in the power distribution cabinet. Long-term high temperature will affect the service life of electronic components in the power distribution cabinet, especially in the In summer, the high temperature inside the power distribution cabinet is more likely to cause a fire. Most of the traditional fire extinguishing methods are to open the door of the power distribution cabinet and then use a fire extinguisher to directly extinguish the fire. However, a large amount of air will enter the power distribution cabinet at the moment the door is opened. Inside, it is easy to make the fire more fierce and dangerous
