Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing, in particular to a fire extinguishing device capable of adjusting the quantity and density of a coolant. Background Art

[0002] Aerosol fire extinguishing devices have high fire extinguishing efficiency and have been applied in energy storage, electricity, wind power and other industries. Since the aerosol generator inside the aerosol fire extinguishing device will generate a lot of high temperature after being activated, the aerosol fire extinguishing device is usually filled with coolant to eliminate the temperature generated by the aerosol fire extinguishing device when extinguishing the fire. However, whether it is a physical coolant or a chemical coolant, the fire extinguishing medium released by the aerosol generator will be attached to the coolant surface to a certain extent on the eruption path of the aerosol fire extinguishing agent, so the fire extinguishing medium released at the nozzle of the fire extinguishing device will be reduced, reducing the fire extinguishing ability, and the greater the density of the coolant, the more fire extinguishing medium will be adsorbed, and the fire extinguishing ability of the device will be further reduced. In addition, the coolant in the fire extinguishing device is too dense, which will cause the nozzle of the fire extinguishing device to be blocked.

[0003] In addition to reducing the spraying temperature of the fire extinguishing device, the coolant currently on the market can also reduce the corrosiveness and sedimentation rate of the aerosol fire extinguishing agent. Therefore, the increase of coolant can usually reduce the sedimentation and corrosion rate when the fire extinguishing agent is sprayed. The greater the coolant density, the higher the contact rate between the coolant and the fire extinguishing agent, and the more obvious the effect will be.

[0004] In summary, the fire extinguishing capacity, other additional effects and the amount and density of the coolant of the aerosol fire extinguishing device are closely related. According to the actual needs of the application environment, some require strong fire extinguishing ability, while others have requirements for corrosiveness and sedimentation rate. In this way, it is necessary to adjust the amount and density of the coolant according to actual needs. Utility Model Content

[0022] Preferably, the starting component 3 is a thermistor structure or an electric starter structure.

When a fire, overheating, etc. occurs, the fire detection device detects that the high temperature environment is generated by the fire outside, and sends a signal to the microprocessor. The microprocessor controls the external power supply to work, so that the electronic ignition head of the starting component 3 ignites, thereby igniting the fire extinguishing agent column 2.

[0023] Preferably, the bottom of the cylinder 1 is threadedly connected to the bottom cover 10 , and a wire hole is provided on the surface of the bottom cover 10 for passing a starting wire of the starting component 3 .

[0024] Preferably, the top surface of the movable screen 8 is rotatably connected to the bottom of the screw 9 through a bearing or a pin. After such a design, the rotation process of the screw 9 will not be affected by the movable screen 8.

[0025] Preferably, the area of ​​the screw 9 above the spray cover 6 is provided with a locking nut 11 threadedly matched with the screw 9. After the screw 9 rotates, the screw 9 can be locked by the locking nut 11 to prevent the screw 9 from rotating during use of the fire extinguishing device.

[0026] Preferably, an operating handle 12 is also provided at the top of the screw rod 9. The operating handle 12 can make the rotation of the screw rod 9 easier, and facilitates the process of operating the screw rod 9 to rotate.

[0027] Preferably, the fire extinguishing agent column 2 is also wrapped with a silica gel layer 2.1. The silica gel layer 2.1 can prevent the cylinder 1 from being overheated during the fire extinguishing process.

[0028] Preferably, the fire extinguishing agent charge 2 is a charge structure formed by pressing aerosol generating agent powder.

[0029] Preferably, the top of the cylinder 1 is threadedly connected to the bottom of the coolant shell 4 , and the top of the coolant shell 4 is threadedly connected to the outer side of the spray cap 6 .

[0030] Preferably, a sealing sticker is also provided on the surface of the nozzle 7. The sealing sticker can prevent moisture in the outside air from entering the cylinder 1 along the nozzle 7 during normal storage and transportation of the fire extinguishing device, thereby avoiding the phenomenon of moisture absorption by the fire extinguishing agent column 2.

[0031] In this embodiment, the coolant 5 can cool down the high-temperature fire extinguishing material generated when the fire extinguishing agent column 2 is ignited to prevent it from being too hot when it is ejected from the nozzle 7; in addition, the coolant 5 can be a physical coolant and / or a chemical coolant, wherein the physical coolant can be one or more combinations of iron chips, ceramic balls, and goose warm stones, and the chemical coolant can be one or more combinations of potassium nitrate, potassium hydrogen tartrate, and ferrocene.

[0032] The working principle of this embodiment is as follows:

[0033] First, the quantity and density of the required coolant are determined according to the requirements of the actual application environment, a certain amount of coolant 5 is filled into the coolant shell 4, and the screw 9 is inserted into the spray cap 6, and then the spray cap 6 is threadedly connected to the top of the coolant shell 4; then, according to the density formula (generally the average density), since the mass of the coolant 5 is constant, the volume of the coolant 5 to be filled can be converted, and since the coolant shell 4 is a circular cylindrical structure, the height of the coolant 5 that needs to be filled in the coolant shell 4 can be obtained; then, the screw 9 can be driven to rotate by rotating the operating handle 12, and since the screw 9 and the movable partition 8 The rotating connection can drive the movable screen 8 to move downward. When the movable screen 8 contacts the top of the coolant 5, it gradually begins to squeeze the coolant 5. When the movable screen 8 reaches the set coolant 5 height position, the density of the coolant 5 is the coolant density required by the actual application environment. Stop turning the operating handle 12, and then screw the locking nut 11 on the screw 9, so that the screw 9 can be locked. After completing the above process, the entire coolant shell 4 is installed on the top of the cylinder 1 (this embodiment adopts a threaded connection method), so that the entire fire extinguishing device completes the assembly process, and the coolant inside reaches the set quantity and density. In actual production, coolant shells with different coolant quantities and densities can be produced according to the actual application environment requirements, and then the corresponding coolant shells and cylinders can be selected for combination and connection.

[0034] After the fire extinguishing device is put into use, when a fire occurs outside, the starting component 3 ignites the fire extinguishing agent column 2. The fire extinguishing agent column 2 in this embodiment is a column compressed by an aerosol generating agent. The fire extinguishing agent column 2 burns to produce a fire extinguishing substance (such as an aerosol or gas); after the fire extinguishing substance is cooled by the coolant 5, it breaks through the sealing sticker and is sprayed out from the nozzle 7 to carry out the fire extinguishing process.
