[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clear that the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figures 1 to 5 The fire linkage control device shown in the figure includes a housing 1, in which an alarm controller 3 is fixedly mounted. Mounting lugs are provided on the housing 1, and bolts engage the lugs to secure the housing 1 to a wall, completing the device installation. The housing 1 is also equipped with a smoke sensor, buzzer, alarm light, and other components for fire monitoring.

[0023] After the installation is completed, the power cord is connected to the alarm controller 3 to power the device, and the alarm controller 3 is connected to the fire protection system to achieve fire protection linkage.

[0024] Taking into account that the existing fire linkage control device does not have the function of automatic fire extinguishing and is easily damaged by the high temperature of the fire, affecting the alarm effect of the fire linkage, a frame tube 4 is fixedly connected to the inside of the box body 1, and a first air outlet channel 5 is opened on the four side outer walls of the box body 1. The first air outlet channel 5 passes through the inner wall of the frame tube 4, and the first air outlet channel 5 is connected to the frame tube 4. A first solenoid valve 6 is fixedly installed inside the first air outlet channel 5.

[0025] A box 7 is fixedly attached to the interior of the housing 1. A slide 8 slides inside the box 7, dividing the interior of the box 7 into an air silo 9 and a material silo 10. The air silo 9 is used to transport gas, while the material silo 10 is used to store fire extinguishing agent. The fire extinguishing agent, made of materials such as sodium bicarbonate and a moisture-proofing agent, is suitable for use with electrical equipment, similar to dry powder fire extinguishing agents, and poses no secondary hazards. Wind ducts 12 are defined on the inner wall of the wind silo 9 and extend through the inner wall of the frame tube 4, connecting the wind silo 9 to the frame tube 4 via these ducts.

[0026] A second air outlet channel 17 is opened on the frame tube 4 , a third solenoid valve 18 is fixedly installed inside the second air outlet channel 17 , and the second air outlet channel 17 faces the alarm controller 3 .

[0027] A fixing clamp 14 is fixedly connected to the interior of the housing 1. A gas cylinder 13 is secured to the fixing clamp 14. Gas cylinder 13 is filled with high-pressure gas, which may be, but is not limited to, nitrogen. A gas pipe 15 is connected to the gas cylinder 13. The end of the gas pipe 15, distal from the gas cylinder 13, is connected to the air chamber 9. A second solenoid valve 16 is fixedly mounted to the gas pipe 15.

[0028] When the temperature around the device rises due to a fire, the slide plate 8 slides downward, causing the volume of the silo 10 to expand, and the silo 10 is connected to the air pipe 15 and the air trough 12, the second solenoid valve 16 and the first solenoid valve 6 are opened, and the high-pressure gas inside the gas cylinder 13 enters the frame tube 4 through the air pipe 15, the silo 10, and the air trough 12, while driving the fire extinguishing agent into the frame tube 4, and the fire extinguishing agent is sprayed outward from the first air outlet channel 5, thereby achieving the effect of extinguishing the fire around the fire linkage control device, reducing the impact of the fire on the device, and ensuring the stability of the fire linkage.

[0029] A pressure compensating device (not shown in the figure) cooperating with the silo 10 is provided on the square box 7. The pressure compensating device includes an air duct, a one-way valve and other structures to ensure that the slide plate 8 can slide downward.

[0030] In the absence of a fire, when the alarm controller 3 becomes hot due to long-term use, the wind bin 9 is connected to the air pipe 15 and the air trough 12, the third solenoid valve 18 and the second solenoid valve 16 are opened, and the high-pressure gas inside the gas cylinder 13 enters the frame tube 4 through the air pipe 15, the wind bin 9, and the air trough 12, and is sprayed toward the alarm controller 3 through the second air outlet channel 17, thereby achieving the effect of forced heat dissipation of the alarm controller 3 and ensuring the effect of fire linkage.

[0031] Compared with using a pump body or other structures, the provision of the gas cylinder 13 has the advantages of occupying less space and being flexible in operation, thereby improving the flexibility of the device.

[0032] By setting up structures such as the frame tube 4, the square box 7 and the slide plate 8, the fire extinguishing agent is sprayed outward from the first air outlet channel 5, thereby achieving the effect of extinguishing the fire around the fire linkage control device, reducing the impact of the fire on the device, and ensuring the stability of the fire linkage; at the same time, the high-pressure gas inside the gas cylinder 13 can also enter the frame tube 4 through the air pipe 15, the wind bin 9, and the air trough 12, and be sprayed toward the alarm controller 3 through the second air outlet channel 17, thereby achieving the effect of forced heat dissipation of the alarm controller 3, thereby ensuring the effect of the fire linkage.

[0033] An electric push rod 11 is fixedly connected to the upper surface of the top of the square box 7. A circular hole is provided on the square box 7 for the telescopic end of the electric push rod 11 to pass through. The slide 8 is fixedly connected to the telescopic end of the electric push rod 11. The electric push rod 11 is provided to adjust and control the position of the slide 8.

[0034] A first temperature sensor 2 is fixedly mounted within the housing 1, near the alarm controller 3. The first temperature sensor 2 is configured to monitor the temperature of the alarm controller 3. Specifically, a controller may be configured to connect between the third solenoid valve 18, the second solenoid valve 16, and the first temperature sensor 2. When the first temperature sensor 2 detects that the temperature exceeds a set threshold, it transmits this information to the controller, which then activates the third solenoid valve 18 and the second solenoid valve 16, respectively. The controller and its control principles are common existing technologies and are not described in detail here.

[0035] A second temperature sensor 19 is fixedly mounted on the outer wall of the housing 1 to monitor fire conditions outside the device. Specifically, a controller may be provided, connected between the first solenoid valve 6, the second solenoid valve 16, and the second temperature sensor 19. When the second temperature sensor 19 detects a temperature exceeding a set threshold, it transmits this information to the controller, which then activates the first solenoid valve 6 and the second solenoid valve 16, respectively. The controller and its control principles are common existing technologies and are not described in detail here.
