Fireproof switch cabinet

Abstract

The invention discloses a fireproof switch cabinet in the field of fire prevention of switch cabinets. The fireproof switch cabinet comprises a protection box, a ventilation window and a sliding groove are formed in the front end face of the protection box, a rack is slidably connected into the sliding groove, a first spring is fixedly connected to the lower end of the rack, and a stop block is fixedly connected to the upper end of the rack; a first square groove is formed in the side end face of the ventilation window, a fixing shaft is rotationally connected into the first square groove, anda gear and a shutter are fixedly connected to the circumferential surface of the fixing shaft; a storage groove is formed in the upper top end face in the protection box and internally and fixedly connected with a second spring, the upper end of the storage groove is in threaded connection with a sealing cover, and the lower end of the storage groove is hinged to an opening-closing plate. A double-thread lead screw is rotationally connected into the protection box and is in threaded connection with a first threaded block and a second threaded block, a supporting rod is fixedly connected to the front end of the first threaded block, a driven wheel is fixedly connected to the front end of the double-thread lead screw, the structure is simple, the manufacturing cost is low, and fire diffusion can be prevented only through simple operation.

Description

technical field [0001] The invention relates to the field of fire prevention of switch cabinets, in particular to a fire protection switch cabinet. Background technique [0002] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, bookstore, power distribution and power conversion in the store system. The components in the switchgear mainly include circuit breakers, isolating switches, coincidence switches, operating mechanisms, transformers and various protective devices. There are many classification methods of switchgear, such as circuit breaker installation method can be divided into removable switchgear and fixed switchgear; or according to the structure of the cabinet, it can be divided into open switchgear, metal-enclosed switchgear and metal-enclosed Armored switchgear; according to the voltage registration, it can be divided into high-voltage switchgear, medium-voltage switchgear ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing switch cabinets can only place the circuit equipment in the switch cabinet, which does not have the effect of fire prevention. When the circuit in the switch cabinet is short-circuited, it is very easy to cause a fire, and the fire cannot be well controlled. Within a certain range, this will cause certain losses to property and also affect personal safety.
