A self-closed heat dissipation hole type fireproof electrical cabinet that can reduce internal oxygen content

Abstract

The invention discloses a self-closed heat dissipation hole type fireproof electrical cabinet capable of reducing the internal oxygen content, which comprises a device body, electrical equipment, a heat dissipation port and a dustproof net. The interior of the device body is fixedly equipped with electrical equipment, and the device The side of the main body is provided with a heat dissipation port, and the inside of the heat dissipation port is fixedly connected with a dust-proof net, and a closing plate is installed outside the heat dissipation port, and the inner end of the closing plate is installed inside the guide column, and the guide post is fixed Installed inside the device body, the outer end of the traction rope is fixedly connected to the outer side of the upper end of the closing plate, and the upper end of the closing plate is fixedly installed with a fixed cover. The self-sealing radiating hole type fireproof electrical cabinet that can reduce the internal oxygen content can effectively block the radiating holes in the event of a fire, preventing the outside air from continuously entering the inside of the electrical cabinet so that it can play a combustion-supporting role for the flames. , and can promptly give an alarm reminder to the surrounding staff.

Description

technical field [0001] The invention relates to the related technical field of electrical cabinets, in particular to a self-closing radiating hole type fireproof electrical cabinet which can reduce the internal oxygen content. Background technique [0002] With the development of society, electric energy is indispensable in some areas and factories. However, in order to effectively protect the electrical equipment during installation, the electrical equipment is usually installed inside the electrical cabinet. The electrical cabinet is passed The cabinet is made of two kinds of steel materials such as hot-rolled steel plate and cold-rolled steel plate. Therefore, the electrical cabinet is widely used in the chemical industry, power system and transportation industry. During the use of the electrical cabinet, in order to ensure good heat dissipation inside Most of the power will set up cooling holes on the side of the electrical cabinet, so that the internal and external air ...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a kind of self-closing radiating hole type fireproof electric cabinet that can reduce the internal oxygen content, to solve the problem that the existing electric cabinets on the market are not convenient to clean the holes on the dustproof net when the interior of the electric cabinet is on fire. Timely sealing, so that when a fire breaks out, it is easy to cause the outside air to continuously enter the inside of the electrical cabinet and provide oxygen to the fire source, thereby greatly reducing the overall fire extinguishing effect, and it is not convenient for the surrounding work when a fire breaks out inside. The personnel play a good alarm and reminder role in time, which leads to the problem of more serious losses and dangers caused by the continuous expansion of the fire due to the inability to remind the staff in time
