[0002] Most fire water sources provide fire water that needs to be pressurized by fire pumps to meet the requirements of water pressure and water volume during fire extinguishing. The switchgear, measuring instruments, protective electrical appliances and auxiliary equipment are assembled in closed or semi-closed metal cabinets. During normal operation, the circuit can be connected with the help of manual or automatic switches, which can automatically start the fire pump.

[0003] However, in actual use, the control cabinet is usually ventilated and cooled through the heat dissipation windows at the bottom and top of both sides. Once a fire occurs on the floor where the control cabinet is located, the air temperature in the floor environment will be high, resulting in poor heat dissipation of the control cabinet. It is also easy to cause toxic or overheated smoke to be inhaled into the cabinet, affecting the normal operation of the internal electrical equipment. Therefore, a device is needed that can conveniently adjust the gas inlet and outlet of the control cabinet and adjust the heat dissipation. Utility Model Content
