Cellular automatic electrical control cabinet with flame-retardant and fire-extinguishing functions

Abstract

The invention belongs to the field of electrical control, and particularly relates to a cellular automatic electrical control cabinet with flame-retardant and fire-extinguishing functions, which comprises a base, a cabinet body is fixedly mounted at the top of the base, a cabinet door is hinged to the outer wall of the cabinet body, and a fixed block is fixedly mounted on the right side of the topof the base. A first electric push rod is fixedly installed on the right side wall of the fixing block, and a piston rod of the first electric push rod penetrates through the fixing block and is hinged to the outer wall of the cabinet door through a hinge. A signal is fed back through the smoke sensor, so that the signal is fed back to the single-chip microcomputer in case of a fire, the single-chip microcomputer starts the electromagnetic valve, the first electric push rod and the second electric push rod to open the cabinet door on the surface of the cabinet body, and meanwhile, the annularpipe moves up and down, so that a compressed fire extinguishing raw material in the fire extinguisher is sprayed out; and meanwhile, the fire around the cabinet body is extinguished in a full-wrapping manner and can be sprayed to the inner cavity of the cabinet body, so that the fire extinguishing effect and efficiency can be improved.

Description

technical field [0001] The invention relates to the field of electrical control cabinets, in particular to a compartmentalized automatic electrical control cabinet with flame-retardant and fire-extinguishing functions. Background technique [0002] The control cabinet is to assemble the switchgear, measuring instrument, protective device and auxiliary equipment in the closed or semiclosed metal cabinet or on the screen width according to the requirements of electrical wiring. and the safety of surrounding equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. 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. Commonly used in v...

Problems solved by technology

[0003] At present, the existing electrical control cabinet is prone to fire in the case of short circuit. The existing electrical control cabinet does not have the function of automatic fire extinguishing, and the staff needs to hold the fire extinguisher to extinguish the fire. However, the fire source is on the inner wall of the cabinet, and the fire extinguisher is not good at extinguishing the fire.
