Electrical power distribution cabinet fire-fighting device

Abstract

An electrical power distribution cabinet fire-fighting device is used for fire extinguishing of a power distribution cabinet. A driving motor is arranged on a fixed supporting plate, and an output shaft of the driving motor is connected with an adjusting screw rod; a water tank is arranged at the left end of the power supply distribution cabinet, a movable plug sleeved with a sealing sleeve is slidably connected with a guide groove of the water tank, the movable plug is in threaded connecting with an adjusting screw rod, a circulating water pipe water guide pipe is fixedly inserted into the water tank, and a nozzle seat is arranged at the lower end of the water guide pipe and arranged at the upper end of an inner cavity of the power supply distribution cabinet body. The lower end face of the nozzle seat is provided with a water outlet hole. A second water guide plate is arranged at the front end part of the nozzle seat; a first water guide plate is arranged at the lower end part of the inner cavity of the power supply distribution cabinet; the lower water end of the first water guide plate is butted with a circulating water pipe; and a temperature sensor is arranged in the power distribution cabinet body. Under the dual effects of the driving motor and the water suction pump, the movable plug is pushed from bottom to top in the inner cavity of the water tank, water is sprayed to the inner cavity of the power distribution cabinet through the effects of the water guide pipe and the nozzle seat, the fire behavior in the power distribution cabinet is reduced at the fastest speed, and the power distribution cabinet is safer and more reliable when used in summer.

Description

technical field [0001] The invention relates to the technical field of electrical distribution cabinets, in particular to a fire-fighting device for electrical distribution cabinets. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. However, the existing power distribution cabinets are easi...

AI Technical Summary

Problems solved by technology

However, the existing power distribution cabinets are easily affected by high temperature during summer use, resulting in high temperature of components inside the power distribution cabinet and causing fires, which greatly reduces the safety of the power distribution cabinet.
