Automatic spraying fire extinguishing device

Abstract

The invention discloses an automatic spraying fire extinguishing device. The automatic spraying fire extinguishing device comprises a water inlet pipe, a blade leading wire and a water outlet pipe. Aswitching valve is arranged at the connection position of the water inlet pipe and the water outlet pipe. One end of the water inlet pipe and one end of the water outlet pipe are connected with the switching valve through sealing sleeves. A spray head is arranged at the other end of the water outlet pipe. A valve is arranged on the surface of one side of the switching valve. According to the automatic spraying fire extinguishing device, when a fire breaks out, a laid leading wire is ignited by a fire source; the leading wire burns fast to reach the portion between a leading wire sleeve and a connecting lug, so that the portion, connected between the leading wire sleeve and the connecting lug, of the leading wire is burnt out; the valve on the switching valve rotates under the effect of a spring hook, so that the valve is switched on; the water inlet pipe communicates with the water outlet pipe, and water is sprayed out of the spray head to extinguish the fire; when the leading wire isburnt to the position of the blade leading wire, the blade leading wire is also ignited and burnt out; a blade rotates under the effect of a spring and a rotating shaft, so that it is guaranteed thatthe portion, between the leading wire sleeve and the connecting lug, of the leading wire is disconnected; and higher safety and convenience are achieved.

Description

Technical field [0001] The invention belongs to the technical field of fire fighting equipment, and specifically relates to an automatic spray fire extinguishing device. Background technique [0002] The automatic sprinkler fire extinguishing device has good safety fire extinguishing performance. It can better reflect the fire extinguishing effect in high-rise buildings that the firefighters cannot take into account and the power supply line is faulty. It is suitable for warehouses with toxic materials and toxic gases. Which floor is on fire and which floor is extinguished, you can use hazardous chemical warehouses, flammable materials, main warehouses, high-rise buildings, restaurants and other places, and easy-to-load water tanks such as fire extinguishing for mobile objects can be used. This fire extinguishing device is mainly composed of signal lines, water switches, drainage devices, etc., when the fire source burns the signal lines, the water switch will be automatically tu...
