DETAILED DESCRIPTION
[0017] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application. Embodiment 1
[0018] Please refer to Figure 1-2 The hot gas aerosol fire extinguishing device with lotus-shaped nozzle comprises an initiating mechanism and a protection mechanism. The initiating mechanism comprises an electric initiator, a starting charge, a sleeve tube, a thermal initiator, a waterproof joint and a cooling ball. The electric initiator and the thermal initiator are fixedly installed on the starting charge and are connected with an external fire extinguishing controller through the sleeve tube. The sleeve tube passes through the cooling ball and is connected with the external environment at the waterproof joint. The protection mechanism comprises an outer cylinder, an inner container, a sealing diaphragm, a fire extinguishing agent, a bottom plate, a nozzle plate, first heat insulation cotton, second heat insulation cotton and a fire barrier net. The starting charge is fixed on the surface of the fire extinguishing agent. The outer cylinder is internally provided with the lotus-shaped nozzle plate and the sealing diaphragm. The first heat insulation cotton is fixedly installed on the outside of the inner container. The inner container is internally provided with the fire barrier net and the second heat insulation cotton. The bottom plate is installed on the inside of the outer cylinder and is different from one side of the sealing diaphragm.
[0019] In the present embodiment, in use, the electric initiator of the hot gas aerosol fire extinguishing device is connected with the fire extinguishing controller. When a fire occurs, the fire detector detects a fire signal. The controller confirms the fire and sends a fire signal to the electric initiator. After receiving the starting signal, the starting charge ignites the starting charge. After the starting charge explodes and opens the protective cover, the starting charge ignites the fire extinguishing agent to generate a large amount of aerosol. The hot gas aerosol passes through the cooling ball and reaches the nozzle plate with the lotus-shaped nozzle of the device. The pressure in the inner cylinder of the fire extinguishing device is instantaneously increased. The sealing diaphragm at the nozzle of the fire extinguishing device is opened. Since each nozzle on the nozzle plate is provided with a sharp spike, the sealing diaphragm can be better pierced when the gas pressure is externally punched. Thus, the generated aerosol is quickly sprayed out to achieve efficient fire extinguishing.
[0020] In the present embodiment, in use, the electric initiator, the thermal wire and the starting charge and other components mainly serve to ignite the fire extinguishing agent in multiple modes. The cooling ball, the first heat insulation cotton and the second heat insulation cotton serve to prevent the shell from overheating when the device is released and serve to cool down. The waterproof joint and the sealing diaphragm can prevent moisture and water from entering the device and serve to seal. The fire barrier net serves to prevent the starting charge from burning and to guide the fire source to the outside. Embodiment 2
[0021] In summary, in use, when the fire detector detects a fire signal, the electrical initiator installed in the sleeve pipe is connected to the starting signal to ignite the starting charge, when the electrical initiator is damaged, the thermal initiator receives the heat transfer signal to ignite the starting charge, and then the starting charge ignites the fire extinguishing agent. When the starting charge ignites, it will produce a fire, and the fire-retardant net inside the inner container will block the fire. The ignition of the fire extinguishing agent produces a large amount of aerosol, which passes through the cooling ball to the nozzle plate with lotus-shaped nozzles of the device, causing the pressure in the outer cylinder of the device to increase instantaneously. This pressure opens the sealing membrane behind the nozzle plate, and since each nozzle on the nozzle plate has a sharp spike, it better pierces the sealing membrane when the gas pressure is released. The first and second heat insulation cottons are damaged when the device releases hot aerosol due to external or internal factors, causing the temperature to be too high and damaging the outer cylinder structure. (One kind of hot aerosol fire extinguishing device with lotus-shaped nozzles in this scheme can be used on the QRR3GW / S-QL type aerosol device produced by our company, and a lotus-shaped nozzle plate can also be customized to adapt to various aerosol fire extinguishing devices.)
[0022] In all the above schemes, the connection between the two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods. In this case, it is not necessary to repeat it here. In the above, whenever there is a fixed connection, welding is preferred. Although embodiments of the present application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
