Description

Technical Field

[0001] This utility model relates to the field of early warning and monitoring technology, and in particular to a fire alarm device for mine ventilation. Background Technology

[0002] Mine fires pose a serious threat to mining production, especially in deep mine environments where early-stage fires are difficult to detect and often spread rapidly, causing severe casualties and equipment damage. With technological advancements, mine fire alarm systems have increasingly adopted advanced sensor technologies (such as smoke, temperature, and gas sensors) to accurately detect early-stage fire signals and enable remote monitoring and management through wireless communication and intelligent technologies. Furthermore, the linkage between the alarm system and the mine ventilation system can effectively control the spread of fire, promptly remove harmful gases and smoke, and reduce fire losses. In summary, through continuous technological innovation and optimization, mine fire alarm systems have significantly improved the emergency response and fire early warning capabilities of mines, providing strong protection for safe production.

[0003] A search revealed an existing patent (publication number: CN216240809U) disclosing a fire alarm device for mine ventilation. The device includes a fixed sleeve fixedly installed at the rear center of a fixed frame, with an alarm unit housed inside the sleeve. Two first transmission frames are symmetrically fixedly installed on the top two sides of the fixed frame. Each of the two first transmission frames has a sliding seat on its exterior. A second transmission frame is fixedly installed between the inner sides of the two sliding seats. A third transmission frame slides on the second transmission frame, and a fixed seat slides on the third transmission frame. A stepper motor is mounted on the fixed seat. This invention provides a fire alarm device for mine ventilation that allows for timely cleaning of dust from the device, effectively improving its precision during use and leading to better application prospects.

[0004] However, in actual use, the above-mentioned solutions are mostly fixed installations. Fixed devices lack flexibility and cannot be adjusted promptly according to changes in the mine environment and work areas, potentially leading to blind spots in monitoring. Secondly, a malfunction in one part can affect the entire system's functionality, causing fire signals to go undetected. Installation and maintenance are also more difficult, especially in deep mines and complex environments. As the mine operates, equipment changes make maintenance of fixed devices even more cumbersome. Fixed alarm devices have limited coverage and cannot cover all changing areas, increasing response delays in the event of a fire. Furthermore, due to dependence on mine environmental conditions such as temperature and humidity, the accuracy of fixed devices may be affected, leading to instability in the alarm system.

[0005] Therefore, this utility model provides a fire alarm device for mine ventilation. Utility Model Content

[0030] The moving component includes a drive wheel 14, which is rotatably connected to a track 1. A first fixing frame 11 is fixedly connected to the top wall of the track 1. A mounting plate 12 is rotatably connected to the outer side of the drive wheel 14. A first motor 13 is fixedly connected to the outer wall of the mounting plate 12. The mounting plate 12 supports and fixes the first motor 13 and also supports and limits the drive wheel 14. The output end of the first motor 13 is fixedly connected to the drive wheel 14. The first motor 13 fixes the drive wheel 14 and drives the drive wheel 14 to rotate. Connecting rods 15 are fixedly connected to both sides inside the mounting plate 12. The connecting rods 15 are fixed by the mounting plate 12 and engage with the support frame 2. The connecting rods 15 fix the support frame 2 to the inner side of the mounting plate 12.

[0031] The rotating assembly includes a second fixed frame 21, which is fixedly connected to the inner wall of the support frame 2. The support frame 2 fixes the second fixed frame 21. A second motor 22 is arranged inside the second fixed frame 21. The output end of the second motor 22 is fixedly connected to the second fixed frame 21. The second motor 22 is fixedly connected to the power supply compartment 3. A limit ring 23 is rotatably connected to the inner side of the support frame 2. The limit ring 23 is fixedly connected to the power supply compartment 3. The power supply compartment 3 fixes the second motor 22. The rotating end of the second motor 22 is fixedly connected to the second fixed frame 21. Thus, when the second motor 22 outputs power, it will rotate itself through stress, thereby driving the power supply compartment 3 to rotate and adjusting the lateral angle of the power supply compartment 3.

[0032] The early warning component includes a third motor 44, which is fixedly connected to the inner wall of the pod 4. The pod 4 simultaneously fixes the third motors 44 on both sides.

The bottom wall of the mixing chamber 45 is fixedly connected to the nozzle 46. The mixing chamber 45 fixes the nozzle 46 and drives the nozzle 46 to rotate synchronously longitudinally.

[0034] An infrared sensor 31 is fixedly connected to one side of the power supply compartment 3, and an optical sensor 32 is fixedly connected to the other side of the power supply compartment 3. By setting the infrared sensor 31 and the optical sensor 32 on the outside of the power supply compartment 3, the location of the goods can be determined more quickly.

[0035] Specifically, when the fire alarm device for ventilation in this mine is working: the first motor 13 drives the drive wheel 14 to rotate outside the track 1, thereby moving the equipment. Then, the second motor 22 rotates, and through stress, drives the power supply compartment 3 to rotate, thereby adjusting the lateral angle of the power supply compartment 3 and the pod 4. Then, the third motor 44 on one side drives the video monitor 47 to rotate longitudinally inside the pod 4, completing the lateral and longitudinal angle adjustment of the video monitor 47. In the event of a fire, the infrared sensor 31 and the optical sensor 32 lock the fire source and move the equipment to the fire source location. Then, the water pump 42 draws the extinguishing agent from the storage tank 48 through the water pipe 41, and then delivers it into the mixing tank 45 through the connecting hose 43. The extinguishing agent is mixed in the mixing tank 45 and then sprayed out through the nozzle 46, thereby intervening in the fire in the early stage of the fire and simultaneously uploading the fire information to the cloud for timely processing.
