The other end of the fixing spring 654 is fixedly connected to the connecting rod 63.

[0020] By adopting the above technical solution, by pulling the handle 653, the handle 653 stretches the fixing spring 654, causing the alloy fixing rod 652 to disengage from the fixing hole on one side of the telescopic rod 651. Then, the support frame 3 is adjusted to a suitable position, and then the handle 653 is released. The fixing spring 654 returns to its original position, causing the alloy fixing rod 652 to be inserted into the fixing hole, thereby completing the fixing of the telescopic rod 651.

[0022] By adopting the above technical solution, the limiting slide bar 655 and the limiting block 656 cooperate to facilitate the limitation of the movement range of the telescopic rod 651.

[0023] In this embodiment, during use: the connecting plate 61 and the first reinforcing rib 62 work together to ensure good connection strength with the upper fixed plate 1; the two connecting rods 63 work together with the two second reinforcing ribs 64 to work with the support frame 3 to ensure good load-bearing strength for the dry powder storage tank 4; by pulling the handle 653, the handle 653 stretches the fixing spring 654, causing the alloy fixing rod 652 to disengage from the fixing hole on one side of the telescopic rod 651; then the support frame 3 is adjusted to a suitable position, and then the handle 653 is released, the fixing spring 654 returns to its original position, causing the alloy fixing rod 652 to insert into the fixing hole, thereby completing the fixing of the telescopic rod 651. This makes the device have high load-bearing strength for the dry powder storage tank 4 during use, and it is easy to adjust the installation height of the dry powder storage tank 4 according to the required installation height. Example 2

[0024] The difference between this embodiment and embodiment 1 is that, specifically, the fastening assembly 7 includes a support plate 71, a fastening screw 72, a rubber fastening block 73, a rotating block 74, and an anti-slip rotating rod 75. The support plate 71 is symmetrically and fixedly connected to both ends of the upper part of the support frame 3. The fastening screw 72 is threadedly connected to the middle of the support plate 71. One end of the fastening screw 72 is fixedly connected to the rubber fastening block 73, and the other end of the fastening screw 72 is fixedly connected to the rotating block 74. The anti-slip rotating rod 75 is fixedly connected around the surface of the rotating block 74.

[0025] By adopting the above technical solution, after the dry powder storage tank 4 is placed in the support frame 3, the rotating block 74 is rotated by the anti-slip rotating rod 75. The rotation of the rotating block 74 will drive the fastening screw 72 to rotate. The rotation of the fastening screw 72 will drive the rubber fastening block 73 to move, so as to fasten and fix the dry powder storage tank 4.

[0026] Specifically, a sponge sleeve 76 is fixedly connected to the surface of the anti-slip rotating rod 75.

[0027] By adopting the above technical solution, the sponge sleeve 76 facilitates improved comfort when forcefully rotating the anti-slip rod 75.

[0028] In this embodiment, after the dry powder storage tank 4 is placed in the support frame 3, the rotating block 74 is rotated by the anti-slip rotating rod 75. The rotation of the rotating block 74 will drive the fastening screw 72 to rotate, and the rotation of the fastening screw 72 will drive the rubber fastening block 73 to move, so as to fasten and fix the dry powder storage tank 4. The sponge soft sleeve 76 can improve the comfort when rotating the anti-slip rotating rod 75 with force, so that the device can be easily disassembled and assembled during use, so as to facilitate its maintenance and replacement.

[0029] The structure and operating principle of the dry powder storage tank 4 and the automatic fire extinguishing component 5 in this utility model have been disclosed in an automatic fire extinguishing device for coal mine roadways disclosed in Chinese Patent Application No. 202421777346.8. Its working principle is as follows: the automatic fire extinguishing component 5 includes a connecting pipe, a spray head, a solenoid valve, a temperature sensor, a pressure sensor, a controller, a ZigBee coordinator, a host management computer, and an Ethernet module. During use, the pressure sensor can acquire the pressure value of the dry powder storage tank 4 in real time. The controller receives the pressure value of the dry powder storage tank 4 and compares it with the pressure setpoint. When the pressure value of the dry powder storage tank 4 is lower than the pressure setpoint, the controller communicates with the ZigBee coordinator through a ZigBee node. The ZigBee coordinator then transmits the signal through its internal network. The controller can promptly detect abnormal pressure in dry powder storage tank 4, eliminating the need for regular manual inspections and reducing labor costs. Temperature sensors acquire real-time ambient temperature values. The controller compares these values ​​with a set temperature. When the set temperature is reached, the controller opens a solenoid valve, allowing the dry powder agent in tank 4 to be sprayed from the nozzles under nitrogen pressure for fire extinguishing. In case of fire, the controller can directly open the solenoid valve for fire suppression. Simultaneously, the controller transmits the ambient temperature value to the ZigBee coordinator via a ZigBee node. The ZigBee coordinator then transmits the ambient temperature value to the controller via the internal network, enabling remote temperature monitoring within the tunnel.

[0030] The working principle and usage process of this utility model: This utility model is used for automatic fire extinguishing in coal mine roadways. In use, the device is installed via the upper fixing plate 1. The connecting component 6, in conjunction with the support frame 3, supports the dry powder storage tank 4, providing high strength. The fastening component 7 allows for easy disassembly and reassembly of the dry powder storage tank 4 placed in the support frame 3. When in use, the connecting component 6, through the cooperation of the connecting plate 61 and the first reinforcing rib 62, ensures a strong connection with the upper fixing plate 1. Two connecting rods 63, in conjunction with two second reinforcing ribs 64, cooperate with the support frame 3, ensuring strong support for the dry powder storage tank 4. Pulling the handle 653 stretches the fixing spring 654, causing the alloy fixing rod 652 to disengage from the fixing hole on one side of the telescopic rod 651. Then, the support frame 3 is adjusted... After adjusting to the appropriate position, release the pull handle 653. The fixed spring 654 returns to its original position, causing the alloy fixing rod 652 to insert into the fixing hole, thus completing the fixing of the telescopic rod 651. This ensures that the device has high load-bearing strength for the dry powder storage tank 4 during use, and facilitates the adjustment of the installation height of the dry powder storage tank 4 according to the required installation height. When using the fastening component 7, after the dry powder storage tank 4 is placed in the support frame 3, the rotating block 74 is rotated by the anti-slip rotating rod 75. The rotation of the rotating block 74 will drive the fastening screw 72 to rotate, and the rotation of the fastening screw 72 will drive the rubber fastening block 73 to move, thereby fastening and fixing the dry powder storage tank 4. The sponge soft sleeve 76 facilitates the comfort when forcefully rotating the anti-slip rotating rod 75, making it easy to disassemble and assemble the dry powder storage tank 4 during use, so as to facilitate its maintenance and replacement.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
