[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution:

[0027] A composite sensor integrated cabinet fire extinguishing device includes a fire extinguishing component 1. Snap-on plates 2 are fixedly installed on both sides of the fire extinguishing component 1. The fire extinguishing component 1 integrates a composite sensor with multiple detection functions, an integrated control unit, a fire extinguishing agent storage and spraying component, signal transmission cables, and a protective outer shell structure. All components are integrated into the cabinet through a modular design, achieving integrated functions of accurate fire detection, rapid response, and effective fire suppression. The composite sensor mainly consists of a thermistor, an infrared scattering smoke sensor, a current transformer, a voltage sensor, a signal conditioning circuit, and a microprocessor data processing unit. The system consists of a processing unit, a communication interface, a power module, and an anti-interference shielding shell. Its working process is as follows: various sensing elements collect physical signals such as temperature changes, smoke particle concentration, and abnormal current and voltage inside the cabinet in real time. After the signal conditioning circuit converts the analog signals into digital signals, they are transmitted to the microprocessor. The microprocessor performs fusion analysis on the multi-source data through a preset algorithm and compares it with the fire threshold parameters. When fire signs such as a sudden rise in temperature exceeding the critical value, excessive smoke concentration, or abnormal current fluctuation are detected, an early warning signal is output to the integrated control unit through the communication interface, providing accurate data support for the triggering of the fire extinguishing device.

[0028] It also includes a snap-fit ​​assembly for fixing the fire extinguishing component 1. The snap-fit ​​assembly includes a fixed snap-fit ​​groove 3 and a movable snap-fit ​​groove 4. The snap-fit ​​plate 2 on one side of the fire extinguishing component 1 is inserted into the fixed snap-fit ​​groove 3. The fixed snap-fit ​​groove 3 is fixedly installed on one side of the pull-out plate 5. The snap-fit ​​plate 2 on the other side of the fire extinguishing component 1 is inserted into the movable snap-fit ​​groove 4. The two sides of the movable snap-fit ​​groove 4 are slidably engaged with the spring rod 6. The spring rod 6 is fixedly installed on the other side of the pull-out plate 5 through the fixed plate 7. A compression spring 11 is slidably sleeved on the surface of the spring rod 6. One end of the compression spring 11 abuts against the fixed plate 7, and the other side of the compression spring 11 abuts against the movable snap-fit ​​groove 4. The movable snap-fit ​​groove 4 is slidably engaged with the pull-out plate 5. A limit block 12 is fixedly installed on the side of the movable snap-fit ​​groove 4 that contacts the pull-out plate 5. The limit block 12 is slidably installed in the limit groove 13. The limit groove 13 is opened in the pull-out plate 5.

[0029] By setting up a snap-fit ​​assembly, the fire extinguishing assembly 1 can be fixed. The snap-fit ​​plates 2 on both sides of the fire extinguishing assembly 1 are respectively inserted through the fixed snap-fit ​​slot 3 and the movable snap-fit ​​slot 4. The fixed snap-fit ​​slot 3 is fixed on the pull-out plate 5, and the movable snap-fit ​​slot 4 is connected to the pull-out plate 5 through the spring rod 6 and is provided with the reset force by the compression spring 11. This allows for simple and quick assembly and disassembly of the fire extinguishing assembly 1. When it is necessary to disassemble, maintain and inspect the fire extinguishing assembly 1, the work efficiency can be significantly improved. At the same time, the limiting block 12 on the movable snap-fit ​​slot 4 cooperates with the limiting groove 13 of the pull-out plate 5 to achieve sliding guidance.

[0030] It also includes a pull-out assembly for moving the fire extinguishing component 1. The pull-out assembly includes a mounting plate 8. Two sets of sliding rods 9 are fixedly installed on the top and bottom of the mounting plate 8. The sliding rods 9 slide in cooperation with the sliding seat 10. The sliding seat 10 is fixedly installed on one side of the pull-out plate 5. Two sets of sliding support plates 20 are fixedly installed in the middle of the side of the pull-out plate 5 near the mounting plate 8. The mounting plate 8 is fixedly installed with a support groove 21. The sliding support plates 20 are slidably installed inside the support groove 21.

[0031] By setting up a pull-out assembly, the fire extinguishing assembly 1 can be moved out of the narrow cabinet. Based on the mounting plate 8, the top and bottom sliding rods 9 slide in cooperation with the sliding seat 10 on the pull-out plate 5, providing stable guidance for the pull-out process. The sliding support plate 20 on one side of the pull-out plate 5 cooperates with the support groove 21 of the mounting plate 8 to enhance the stability of the pull-out plate 5. When the fire extinguishing assembly 1 needs to be inspected and maintained, it can be pulled out of the cabinet along the sliding rod 9 using the pull-out assembly, so that the fire extinguishing assembly 1 is freed from the compact internal space, making it convenient for operators to inspect and maintain it at close range. After the inspection and maintenance are completed, it can be easily pushed back to its original position, thus effectively solving the problem of difficult maintenance of traditional fire extinguishing devices in cabinets due to narrow space.

[0032] A pin seat 14 is fixedly installed in the middle of the side of the movable slot 4 away from the pull-out plate 5. A positioning pin 15 is pinned inside the pin seat 14. A pin hole 16 is opened on the surface of the snap-fit ​​plate 2 on the other side of the fire extinguishing assembly 1. The positioning pin 15 passes through the pin hole 16 and slides with the pin hole 16. A locking groove 17 is opened in the pin seat 14. A locking rod 18 is fixedly installed at one end of the positioning pin 15. The locking rod 18 slides with the locking groove 17. The other end of the positioning pin 15 passes through the pull-out plate 5 and slides with the pull-out plate 5. The other end of the positioning pin 15 is pinned inside the positioning seat 19. The positioning seat 19 is fixedly installed on the mounting plate 8.

[0033] By setting up the pin seat 14 and positioning pin 15 and other structures to work together, the fire extinguishing component 1 can be firmly locked to ensure that it will not loosen or shift during normal operation in the cabinet. The pin seat 14 is fixedly installed on the movable slot 4, and the positioning pin 15 is pinned into the pin seat 14. When the snap plate 2 on one side of the fire extinguishing component 1 is inserted into the fixed slot 3 and the other side is inserted into the movable slot 4, the positioning pin 15 is pushed through the pin seat 14 on the movable slot 4 and inserted into the pin hole 16 of the snap plate 2, so that the fire extinguishing component 1 and the movable slot 4 are tightly connected. At the same time, the locking rod 18 and the locking groove 17 cooperate to prevent the positioning pin 15 from accidentally falling off, thereby firmly fixing the fire extinguishing component 1. In addition, the positioning pin 15 cooperates with the positioning seat 19 to fix the relative position of the pull plate 5 and the mounting plate 8, so as to prevent the fire extinguishing component 1 from shifting due to cabinet vibration and other factors. During maintenance, simply rotate the positioning pin 15 and pull it out to release the locking of the snap plate component and the pull plate component at the same time, which facilitates quick disassembly and maintenance.

[0034] In practical use, the device is installed in the designated position inside the cabinet using the mounting plate 8. First, insert the snap-fit ​​plate 2 on one side of the fire extinguishing component 1 into the fixed slot 3. Then, push the movable slot 4 to compress the compression spring 11. After aligning the snap-fit ​​plate 2 on the other side with the movable slot 4, release the movable slot 4. Under the action of the compression spring 11, the movable slot 4 resets and clamps the snap-fit ​​plate 2. Then, push the positioning pin 15 to pass through the pin hole 16 of the pin seat 14 and the snap-fit ​​plate 2, and rotate the positioning pin 15 to make the locking rod 18 engage with the locking groove 17. At the same time, the other end of the positioning pin 15 engages with the positioning seat 1. 9. Connect the pins to fix the position of the pull-out plate 5 and the mounting plate 8, completing the installation and fixing of the fire extinguishing component 1. When maintenance is required, rotate the positioning pin 15 to unlock the locking rod 18 from the locking groove 17, then pull out the positioning pin 15 to release the lock on the fire extinguishing component 1 and the pull-out plate 5. Pull the pull-out plate 5, and the fire extinguishing component 1 can be pulled out of the cabinet through the sliding cooperation of the slide rod 9 and the slide seat 10 for inspection and maintenance. Alternatively, the fire extinguishing component 1 can be removed for maintenance by pulling the movable slot 4. After maintenance, reverse the operation to push the fire extinguishing component 1 back to its original position and re-fix it.
