Automatic fire extinguishing device for box-type transformer substation

Abstract

The invention discloses an automatic fire extinguishing device for a box-type transformer substation. The automatic fire extinguishing device comprises a top plate, a side plate, a push rod motor, a PLC, a sliding plate, a sliding groove, a first gear plate, a rotating shaft, a dry powder fire extinguisher, a large gear, a friction washer, a U-shaped plate, a sliding track, a sliding toothed plate, a baffle, a safety pin, a connecting rod, a rotating rod, a pinion, a transmission gear, a second gear plate, an L-shaped connecting plate, a positioning rod, a mounting hole, a plastic ring, a pressing plate and a smoke sensor; the top plate is welded to the top of the side plate; the push rod motor is vertically welded to the bottom of the top plate; an output shaft of the push rod motor is fixedly connected with the top of the sliding plate; the inner wall of the side plate is provided with the sliding groove; the sliding plate is installed in the sliding groove; the sliding plate is slidably connected with the side plate; the first gear plate is fixedly connected with the lower end of one side of the sliding plate; and one side of the first gear plate is provided with the rotating shaft. The fire extinguishing device is driven by the push rod motor only, the cost is low, and automatic fire extinguishing can be achieved.

Description

technical field [0001] The invention relates to the field of substations, in particular to an automatic fire extinguishing device for box-type substations. Background technique [0002] Box-type substation, also known as prefabricated substation or prefabricated substation. It is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory prefabricated indoor and outdoor compact power distribution device arranged according to a certain wiring scheme, which is to organically combine functions such as transformer step-down and low-voltage power distribution. Together, they are installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box, which is especially suitable for urban network construction and transformation. A brand new substation. The box-type substation is suitable for mines, factories, enterprises, oil and gas ...

AI Technical Summary

Problems solved by technology

[0003] The existing box-type substation has poor fire performance, relatively high temperature in summer, and large power consumption. The substation is prone to fire. If no fire-fighting measures are taken, it will cause serious loss of life and property.
