Problems solved by technology

However, under normal circumstances, the structure of the electrical control cabinet is relatively complicated. After the installation of the electrical components in it, many small spaces will be formed. The "fire wind pressure" can also cause the superfine dry powder to be blown away and swept away, which greatly reduces the efficiency of fire extinguishing

Abstract

The invention discloses a centrifugal ultrafine dry powder fire extinguishing device which comprises an outer cylinder, a dry powder storage tank and a motor. A first long seam extending in the axial direction is formed in the side wall of the outer cylinder. The two ends of the outer cylinder are connected with an upper cover and a lower cover correspondingly. A second long seam extending in the axial direction is formed in the side wall of the dry powder storage tank. A rotary shaft is arranged on the dry powder storage tank. The upper end of the rotary shaft penetrates out of the upper cover. The motor is in transmission connection with the rotary shaft through a transmission mechanism. According to the centrifugal ultrafine dry powder fire extinguishing device disclosed by the invention, the structure is simple, ultrafine dry powder is sprayed out of the long seams through the centrifugal spraying theory, thus, the ultrafine dry powder has a certain speed and can be rapidly spread into a narrow space in an electric control cabinet, and the ultrafine dry powder can be prevented from being blown away or carried away.

Description

technical field [0001] The invention belongs to the field of fire fighting equipment, in particular to a centrifugal ultrafine dry powder fire extinguishing device. Background technique [0002] At present, the fire extinguishing device used in the electrical control cabinet is basically an ultra-fine dry powder fire extinguishing device. After the ultra-fine dry powder in the ultra-fine dry powder fire extinguishing device is released through the ordinary nozzle installed in the cabinet, it diffuses into the electrical control cabinet in a dispersed form to realize fire extinguishing. Effect. However, under normal circumstances, the structure of the electrical control cabinet is relatively complicated. After the installation of the electrical components in it, many small spaces will be formed. The "fire wind pressure" can also cause the ultra-fine dry powder to be blown away and swept away, which greatly reduces the efficiency of fire extinguishing. Contents of the inven...
