Description

Technical Field

[0001] The invention relates to the technical field of fire extinguishing devices, in particular to an intelligent wireless automatic fire extinguishing device. Background Art

[0002] The intelligent wireless automatic fire extinguishing device is used to automatically detect and extinguish fires in the early stages of a fire to reduce the losses caused by the fire. The device uses wireless transmission technology, combined with an intelligent sensing system and fire extinguishing agents, to achieve automatic detection and extinguishing of fires. When the sensing system detects the source of fire, it will immediately start the fire extinguishing device, release the fire extinguishing agent, and extinguish the fire. Intelligent wireless automatic fire extinguishing devices are widely used in homes, offices, warehouses, museums, libraries and other places, providing strong protection for the safety of people's lives and property. The device is easy to operate and only requires regular inspection and maintenance. The intelligent wireless automatic fire extinguishing device uses environmentally friendly fire extinguishing agents that are harmless to the atmosphere and the environment. At the same time, the device has energy-saving characteristics and will only start working when a fire source is detected, reducing energy consumption.

[0003] The prior art provides an intelligent wireless automatic fire extinguishing device (Announcement No.: CN216148933U), which includes a main body, a nozzle and an air guide groove, and is characterized in that a dry powder nozzle is opened in the middle of the nozzle, and the air guide grooves are evenly and obliquely distributed on the surface of the nozzle, and each air guide groove is surrounded by the dry powder nozzle.

[0004] But the device still has the following defects:

[0005] When the device is in use, the device directly discharges the internal dust. When there is only smoke at the lower end of the device, the dust will be wasted. When the fire spreads to the lower end of the device, the amount of dust inside the device is not much, which will affect the efficiency of fire extinguishing. The gas is stored inside the main body, and the air pressure will affect the operation of the electronic components inside the device. At the same time, the gas is stored inside the main body, and there are greater requirements for the sealing of the main body. However, when maintaining the electrical appliances inside the device, the device needs to be disassembled, which will affect the sealing of the device. Therefore, we need to propose an intelligent wireless automatic fire extinguishing device. Summary of the invention

[0006] The purpose of the present invention is to provide an intelligent wireless automatic fire extinguishing device, wherein the telescopic rod controls the position of the first sealing plate. When the smoke sensor detects smoke, the control box controls the telescopic rod to drive the first sealing plate to move away, and at the same time controls the solenoid valve on the hose to open, and the nitrogen blows out the dust inside the dust cylinder, and the elastic plate at the lower end of the dust cylinder opens and sprays out from the position where the first movable plate is moved away. When the fire moves to the lower end of the device, the heat will be transferred to the upper part, and the heat conduction plate transfers the heat to heat the airbag, and the airbag expands due to the heat. At the same time, under the limiting action of the limiting shell, the airbag drives the connecting rod to move in the direction away from the second sealing plate, and the connecting rod drives the second sealing plate to move, so that more dust is sprayed out, which is convenient for fire extinguishing work, so as to solve the problems raised in the above background technology.
