Detailed Implementation

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0033] Example:

[0034] Reference Figures 1 to 4The system includes a mounting bracket 1 and a controller body 2. The mounting bracket 1 is fixedly connected to the wall by bolts. A placement slot 3 is provided on one side of the mounting bracket 1, and the controller body 2 is located in the placement slot 3. Several first springs 4 are fixedly connected between the controller body 2 and the inner wall of the placement slot 3. In the initial state, the first springs 4 are in their natural state, and part of the controller body 2 is located outside the placement slot 3, which facilitates the operator's inspection and maintenance of the fire controller.

[0035] An air pump 5 is installed above the mounting bracket 1. A fire detector 13 is fixedly connected to the bottom of the mounting bracket 1. A PLC controller (not shown in the figure) is installed inside the mounting bracket 1. Both the fire detector 13 and the air pump 5 are electrically connected to the PLC controller. When a fire occurs, the fire detector 13 can detect the fire and transmit the signal to the PLC controller. The PLC controller controls the air pump 5 to work, improving the timeliness of the fire protection control system.

[0036] A nitrogen storage tank 11 is fixedly connected to the top of the mounting bracket 1, and the nitrogen storage tank 11 contains nitrogen. A gas pump 5 is fixedly connected to one side of the nitrogen storage tank 11, and the input end of the gas pump 5 is connected to the nitrogen storage tank 11. Nitrogen is non-combustible and economical.

[0037] The inner top and bottom walls of the placement groove 3 are both provided with side grooves 6. Fireproof baffles 7, made of asbestos material, are interference-fitted into the side grooves 6, providing fireproof and heat insulation. A second spring 8 is fixedly connected between the fireproof baffle 7 and the corresponding inner wall of the side groove 6. A first pipe 10 is connected to one side of the side groove 6 and communicates with the placement groove 3. When the two fireproof baffles 7 move synchronously to close the opening of the placement groove 3, the fireproof baffles 7 just pass over the first pipe 10, allowing airflow from the side grooves 6 to enter the placement groove 3 through the first pipe 10.

[0038] A linkage 9 is provided between the controller body 2 and the side slot 6. The linkage 9 includes a placement cavity 91 opened in the fixed frame 1. The output end of the air pump 5 is connected to both placement cavities 91 through a diversion valve. The diversion valve makes the air flow rate delivered by the air pump 5 to the two placement cavities 91 the same.

[0039] A rotating rod 92 is rotatably connected within the placement cavity 91. A first collecting plate 93 and two second collecting plates 94 are fixedly sleeved on the outer circumference of the rotating rod 92. A piston 95 (airtight fit) is interference-fitted within the placement cavity 91. A first rope 96 and a second rope 97 are respectively attached to the outer circumferences of the first collecting plate 93 and the second collecting plate 94. The end of the second rope 97 away from the second collecting plate 94 is fixedly connected to the piston 95. The first rope 96 slides through the interior of the fixing frame 1 and is fixedly connected to the controller body 2. Both the first rope 96 and the second rope 97 are in a taut state. Under normal conditions, the rotating rod 92 is held in place by a torsion spring.

[0040] The side of the placement chamber 91 furthest from the output end of the air pump 5 is connected to the corresponding side slot 6 via a pipe. A C-shaped tube 98 is connected to one side of the placement chamber 91, with both ends of the C-shaped tube 98 connected to the placement chamber 91. In the initial state, the piston 95 blocks the end of the C-shaped tube 98 near the corresponding rotating rod 92.

[0041] In the event of a fire, the gas pump 5 operates, supplying nitrogen into the two placement chambers 91. The nitrogen pushes the piston 95 away from the rotating rod 92. As the piston 95 moves, it pulls the rotating rod 92 through the second rope 97. The rotation of the rotating rod 92 causes the first rope 96 to gradually wrap around the first collection tray 93, pulling the controller body 2 into the placement groove 3, compressing the first spring 4. The process continues until the piston 95 moves past the inverted tube 98 and approaches one end of the rotating rod 92. At this point, nitrogen can pass through the inverted tube 98, over the piston 95, and into the side groove 6. The piston 95 then stops moving, and the controller body 2 also stops moving.

[0042] Nitrogen gas enters the side slot 6, pushing the fireproof baffle 7 outward. The second spring 8 extends, generating a reverse elastic force. At this time, since the controller body 2 has already retracted into the placement slot 3, it will not obstruct the outward movement of the fireproof baffle 7. Therefore, the two fireproof baffles 7 continue to move until they fit together, completely covering the placement slot 3 and closing it, so that the controller body 2 is not exposed to the combustion air. At this time, the fireproof baffle 7 passes over the first pipe 10, and nitrogen gas enters the placement slot 3 through the first pipe 10, filling the area around the controller body 2 with nitrogen gas. Since nitrogen gas does not support combustion, it further improves the fireproof effect of the controller body 2.

[0043] Each side of the controller body 2 is movably connected to a number of ball bearings 12, which fit against the inner wall of the placement groove 3. The ball bearings 12 ensure stable horizontal movement of the controller body 2 without tilting, while also leaving a gap between the controller body 2 and the inner wall of the placement groove 3. Nitrogen gas can be filled between the controller body 2 and the inner wall of the placement groove 3, reducing heat transfer from the placement groove 3 to the controller body 2 and further protecting the safety of the controller body 2.

[0044] The bottom of the mounting bracket 1 has a bottom groove 14, and several lower pipes 15 are hinged to the top wall of the bottom groove 14. A nozzle 16 is fixedly connected to the bottom of each lower pipe 15. The lower halves of the lower pipes 15 are movably connected to a connecting pipe 17, which communicates with all the lower pipes 15. A flexible hose 18 is fixedly inserted through one side of the placement groove 3. The flexible hose 18 extends into the bottom groove 14 and communicates with the connecting pipe 17. The flexible hose 18 can be bent and deformed without obstructing the rotation of the lower pipes 15.

[0045] After the placement tank 3 is filled with nitrogen, the nitrogen will enter the connecting pipe 17 and each lower pipe 15 through the hose 18, and be sprayed out through the nozzle 16, thereby increasing the nitrogen content near the fixing frame 1 and thus reducing the degree of combustion.

[0046] An adjustment section 19 is provided above the bottom groove 14. The adjustment section 19 includes a vertical rod 191, the upper end of which is rotatably connected to the inner top wall of the corresponding I-shaped tube 98, and the lower end of which extends into the bottom groove 14. An impeller 192 is fixedly sleeved on the outer circumference of the vertical rod 191 inside the I-shaped tube 98, and a cam 193 is fixedly sleeved on the outer circumference of the vertical rod 191 inside the bottom groove 14. A third spring 194 is fixedly connected between one of the lower tubes 15 and the inner wall of the bottom groove 14.

[0047] When nitrogen passes through the I-shaped tube 98, it drives the impeller 192 to rotate. The impeller 192 drives the vertical rod 191 and the cam 193 to rotate. When the cam 193 rotates, it intermittently contacts the corresponding lower tube 15. In conjunction with the third spring 194, it drives several lower tubes 15 to swing and reciprocate, which increases the range of nitrogen emission and thus improves the fire prevention effect.

[0048] The implementation principle of the above embodiments is as follows:

[0049] In the initial state, the first spring 4 and the second spring 8 are in their natural state, and the piston 95 blocks the end of the I-shaped tube 98 near the corresponding rotating rod 92 (e.g., Figure 1 (As shown).

[0050] When a fire occurs near the fire control panel, the fire detector 13 can detect the fire and transmit the signal to the PLC controller. The PLC controller controls the air pump 5 to operate, and the air pump 5 delivers nitrogen gas into the two placement chambers 91. The nitrogen gas pushes the piston 95 to move. When the piston 95 moves, it pulls the rotating rod 92 to rotate through the second rope 97. The rotation of the rotating rod 92 causes the first rope 96 to gradually wrap around the first collection tray 93, pulling the controller body 2 into the placement groove 3, and compressing the first spring 4. Until the piston 95 moves past the inverted tube 98 and approaches one end of the rotating rod 92, at which point the nitrogen gas can pass through the inverted tube 98, pass over the piston 95, and enter the side groove 6. The piston 95 stops moving, and the controller body 2 also stops moving.

[0051] Nitrogen gas enters the side slot 6, pushing the fireproof baffle 7 to move. The second spring 8 extends. At this time, since the controller body 2 has already retracted into the placement slot 3, it will not obstruct the movement of the fireproof baffle 7. Therefore, the two fireproof baffles 7 continue to move until they are in contact, completely covering the placement slot 3 and preventing the controller body 2 from being exposed to the combustion air. At this time, the fireproof baffle 7 passes over the first pipe 10, and nitrogen gas enters the placement slot 3 through the first pipe 10, filling the area around the controller body 2 with nitrogen gas. Since nitrogen gas does not support combustion, it further improves the fireproof effect of the controller body 2.

[0052] After the placement tank 3 is filled with nitrogen, the nitrogen will enter the connecting pipe 17 and each lower pipe 15 through the hose 18, and be sprayed out through the nozzle 16, increasing the nitrogen content near the fixing frame 1, thereby reducing the degree of combustion. When the nitrogen passes through the inverted tube 98, it drives the impeller 192 to rotate. The impeller 192 drives the vertical rod 191 and the cam 193 to rotate. When the cam 193 rotates, it intermittently contacts the corresponding lower pipe 15. With the help of the third spring 194, it drives several lower pipes 15 to swing back and forth, increasing the nitrogen emission range and thus improving the fire prevention effect.

[0053] After the fire is extinguished, under the regulation of fire detector 13 and PLC controller, air pump 5 is turned off, fireproof baffle 7 returns to its original position under the restoring force of second spring 8, and rotating rod 92 rotates in the opposite direction to its original position under the restoring force of first spring 4, driving piston 95 and controller body 2 to return to their original positions.

[0054] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
