Summary of the Invention
[0005] The purpose of this invention is to provide an adaptive flame-retardant fire prevention and control device for goaf fires, so as to solve the problem of excessively high investment costs caused by the limited range of fire detection in goaf areas.

A telescopic ball moves, causing a fixed column to move; the fixed column moves, causing a fixed plate to move; the fixed plate moves, causing a conveyor box to move; and the conveyor box moves, causing a sensor to move. This allows the sensor to reciprocate along the track and perform continuous area monitoring of the goaf area, completely eliminating blind spots in fire monitoring, significantly reducing equipment investment costs, and improving the efficiency of the device in monitoring fires in goaf areas.
[0007] The scraping mechanism includes a reciprocating screw, a sliding plate, a fixed ring, a telescopic ball, and a fixed post. A motor is installed at the front of the track.

[0011] In one or more embodiments of the present invention, the rotating mechanism includes a cam, an elastic telescopic plate, an arc-shaped plate, a second fixed column, a first slider, a third fixed column, a second slider, and a connecting rod.

[0012] In one or more embodiments of the present invention, the rotating mechanism further includes a fixed block, a movable block, an elastic telescopic rod, and a rotating plate. The fixed block is fixedly connected to the front of the slider, the movable block is slidably connected to the top of the arc-shaped plate, the fixed end of the elastic telescopic rod is fixedly connected to the inner wall of the track, and the rotating plate is rotatably connected to the top of the arc-shaped plate by a torsion spring. The surface of the rotating plate is provided with protrusions, which can lock the movable block. When the device moves towards the middle of the track, the slider moves towards the side closer to the fixed column due to the reset action of the spring on the fixed column. The slider contacts the elastic telescopic plate, which then moves the elastic telescopic plate up along the arc-shaped surface. When the device moves to one end, it rotates. This allows for detection on both sides of the device, expanding the monitoring range and achieving full coverage of the device. It avoids detection errors caused by angle offset and obstruction, and significantly improves the efficiency of prevention and control monitoring.
[0013] In one or more embodiments of the present invention, the arc-shaped plate is located on the motion trajectory of the cam, the connecting rod is rotatably connected to the left side of the second slider, the second slider is located on the motion trajectory of the slide plate, the moving block is fixedly connected to the telescopic end of the first elastic telescopic rod, the moving block is in contact with the second slider, one side of the first rotating plate is located on the motion trajectory of the first slider, and the first rotating plate is located on the motion trajectory of the moving block. At this time, the moving block contacts the rotating elastic telescopic plate, which allows the elastic telescopic plate to rotate and reset more quickly, extending the equipment life. Applying a moving thrust during rotation can achieve continuous reciprocating motion without interruption, preventing the device from failing to reset accurately due to insufficient rotational force during rotation, thus reducing the monitoring effect. This ensures that the device always maintains an accurate position for monitoring and reduces the equipment failure rate.
[0014] In one or more embodiments of the present invention, the locking mechanism includes a pull rope, a first movable plate, a second movable plate, a fourth fixed post, and a collar. The first movable plate is slidably connected to the bottom of the fixed plate. The pull rope is fixedly connected to the front of the first movable plate. A spring is sleeved on the circumferential surface of the pull rope. The second movable plate is fixedly connected to the rear of the first movable plate.

The locking box is fixedly connected to the bottom of the fixed plate, the inclined block is fixedly connected to the inner wall of the locking box, the fixed end of the second elastic telescopic rod is fixedly connected to the inner wall of the locking box, the pressure block is fixedly connected to the telescopic end of the second elastic telescopic rod, and the second rotating plate is rotatably connected to the rear of the second moving plate. When the second moving plate moves out of the fourth fixed column, the fourth fixed column contacts and locks the collar, causing the collar to fall off from the fourth fixed column. This allows for the replacement and inspection of the fire extinguisher. The structure is simple, with few potential failure points, making maintenance and replacement easier for staff and ensuring that all staff can perform maintenance and replacement of the fire extinguisher.
[0016] In one or more embodiments of the present invention, the collar is sleeved with the fire extinguisher, the second movable plate is in contact with the fourth fixed column, the second movable plate is in contact with the collar, the second movable plate is in contact with the locking box, the inclined block is located on the movement trajectory of the second rotating plate, and the pressure block is located on the movement trajectory of the second rotating plate. During the rotation of the second rotating plate, the second elastic telescopic rod squeezes the second rotating plate. Due to the spring reset effect of the second elastic telescopic rod, the pressure block can better fix the second rotating plate, preventing the second movable plate from moving out of the locking box and falling off during the movement of the device, thus avoiding safety accidents from the source and reducing the failure rate.
[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] 1. This adaptive flame-retardant fire prevention and control device for goaf fires utilizes the coordinated operation of a reciprocating screw, sliding plate, fixed ring, telescopic ball, fixed column, fixed plate, conveyor box, sensor, spray nozzle, and rotating column. This allows the sensor to reciprocate along the track and perform continuous area monitoring of the goaf, completely eliminating blind spots in fire monitoring, significantly reducing equipment investment costs, and improving the efficiency of fire monitoring in goaf areas. Simultaneously, it can scrape the surface of the spray nozzle to thoroughly remove impurities such as nozzle end faces, loose coal, and dust clumps, preventing nozzle blockage during use and ensuring that the spray pressure, atomization effect, and coverage area always meet standards.

[0033] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0034] like Figures 1-10 As shown, one embodiment of the present invention is: an adaptive flame-retardant fire prevention and control device for goaf fires, including a track 1, a fire extinguishing tank 2 at the bottom of the track 1, a scraping mechanism 3 at the bottom of the track 1, a rotating mechanism 4 on the inner wall of the track 1, and a locking mechanism 5 at the bottom of the track 1, which enables the sensor 308 to move back and forth on the track 1 and perform continuous area monitoring of the goaf along the entire line, completely eliminating blind spots in fire monitoring, significantly reducing equipment investment costs, and improving the efficiency of the device in monitoring fires in goaf areas.
[0035] The scraping mechanism 3 includes a reciprocating screw 301, a sliding plate 302, a fixed ring 303, a telescopic ball 304, and a fixed column 305. A motor is installed at the front of the track 1. The reciprocating screw 301 is rotatably connected to the inner wall of the track 1 and is fixedly connected to the output end of the motor. The sliding plate 302 is movably connected to the circumferential surface of the reciprocating screw 301. The fixed ring 303 is fixedly connected to the bottom of the sliding plate 302. The fixed column 305 is rotatably connected to the inner wall of the fixed ring 303. The fixed end of the telescopic ball 304 is fixedly connected to the circumferential surface of the fixed column 305.
[0036] The scraping mechanism 3 also includes a fixing plate 306, a conveying box 307, a sensor 308, and a spray nozzle 309. The fixing plate 306 is fixedly connected to the bottom of the fixing column 305, the conveying box 307 is fixedly connected to the left side of the fixing plate 306, the sensor 308 is fixedly connected to the left side of the conveying box 307, and the spray nozzle 309 is fixedly connected to the left side of the conveying box 307.
[0037] The scraping mechanism 3 also includes a rotating column 310, a brush 311, a spur gear 312, and teeth 313. The rotating column 310 is rotatably connected to the inner wall of the conveyor box 307, the brush 311 is fixedly connected to the circumferential surface of the rotating column 310, the spur gear 312 is fixedly connected to the circumferential surface of the rotating column 310, and the teeth 313 are fixedly connected to the left and right sides of the track 1.
[0038] The slide plate 302 is slidably connected to the inner wall of the track 1, the telescopic ball 304 is in contact with the inner wall of the fixed ring 303, the conveying box 307 is connected to the fire extinguishing tank 2, the brush 311 is in contact with the spray nozzle 309, and the spur gear 312 meshes with the tooth 313. At the same time, it can scrape the surface of the spray nozzle 309, which can thoroughly remove impurities such as the end face of the spray nozzle 309, floating coal, and dust clumps, and prevent the spray nozzle 309 from being blocked during use, so as to always ensure that the spray pressure, atomization effect and coverage of the spray nozzle 309 meet the standards.
[0039] Working principle: When the device is started, the operator starts the motor. The motor output drives the reciprocating screw 301 to rotate. The rotation of the reciprocating screw 301 drives the sliding plate 302 to rotate. Due to the limiting effect of the track 1 on the sliding plate 302, the sliding plate 302 moves back and forth on the circumference of the reciprocating screw 301 during the rotation of the reciprocating screw 301. The reciprocating movement of the sliding plate 302 drives the fixed ring 303 to move back and forth. The movement of the fixed ring 303 drives the telescopic ball 304 to move. The movement of the telescopic ball 304 drives the fixed column 305 to move. The movement of the fixed column 305 drives the fixed plate 306 to move. The movement of the fixed plate 306 drives the conveyor box 307 to move. The movement of the conveyor box 307 drives the sensor 308 to move. Thus, the sensor 308 can move back and forth on the track 1 and perform full-area continuous planar monitoring of the goaf area, completely eliminating blind spots in fire monitoring, significantly reducing equipment investment costs, and improving the efficiency of the device in monitoring fires in the goaf area.
[0040] During the reciprocating motion of the conveyor box 307, the reciprocating motion of the conveyor box 307 drives the rotating column 310 to move. The movement of the rotating column 310 drives the spur gear 312 to move. Due to the meshing of the spur gear 312 and the teeth 313, the spur gear 312 rotates during its movement. The rotation of the spur gear 312 drives the rotating column 310 to rotate. The rotation of the rotating column 310 drives the brush 311 to rotate, which in turn scrapes the surface of the spray nozzle 309. This thoroughly removes impurities such as the end face of the spray nozzle 309, floating coal, and dust clumps, preventing the spray nozzle 309 from becoming blocked during use and ensuring that the spray pressure, atomization effect, and coverage of the spray nozzle 309 always meet the standards.
[0041] like Figures 1-10 As shown, in another embodiment of the present invention based on the above embodiments: the rotating mechanism 4 includes a cam 401, an elastic telescopic plate 402, an arc plate 403, a second fixed column 404, a first slider 405, a third fixed column 406, a second slider 407, and a connecting rod 408. The cam 401 is fixedly connected to the rear of the fixed plate 306, the elastic telescopic plate 402 is fixedly connected to the top of the cam 401, the arc plate 403 is fixedly connected to the bottom of the track 1, the second fixed column 404 is fixedly connected to the inner wall of the track 1, the first slider 405 is slidably connected to the circumferential surface of the second fixed column 404, the third fixed column 406 is fixedly connected to the inner wall of the track 1, a spring is sleeved on the circumferential surface of the third fixed column 406, the second slider 407 is slidably connected to the circumferential surface of the third fixed column 406, and the connecting rod 408 is rotatably connected to the front of the first slider 405.
[0042] The rotating mechanism 4 also includes a fixed block 409, a movable block 410, an elastic telescopic rod 411, and a rotating plate 412. The fixed block 409 is fixedly connected to the front of the slider 405. The movable block 410 is slidably connected to the top of the arc plate 403. The fixed end of the elastic telescopic rod 411 is fixedly connected to the inner wall of the track 1. The rotating plate 412 is rotatably connected to the top of the arc plate 403 by a torsion spring. The surface of the rotating plate 412 is provided with protrusions. The protrusions on the surface of the rotating plate 412 can lock the movable block 410, enabling detection on both sides of the device, expanding the monitoring range of the equipment, achieving full coverage of the equipment, avoiding detection errors caused by angle offset and obstruction, and greatly improving the efficiency of prevention and control monitoring.
[0043] The arc plate 403 is located on the motion trajectory of the cam 401. The connecting rod 408 is rotatably connected to the left side of the second slider 407. The second slider 407 is located on the motion trajectory of the slide plate 302. The moving block 410 is fixedly connected to the telescopic end of the first elastic telescopic rod 411. The moving block 410 is in contact with the second slider 407. One side of the rotating plate 412 is located on the motion trajectory of the first slider 405. The rotating plate 412 is located on the motion trajectory of the moving block 410. At the same time, a moving thrust is applied during rotation, which can achieve continuous reciprocating motion without interruption. This prevents the device from failing to accurately reset due to insufficient rotational force during rotation, which would lead to a decrease in monitoring effect. This ensures that the device always maintains an accurate position for monitoring and reduces the failure rate of the equipment.
[0044] The locking mechanism 5 includes a pull rope 501, a first movable plate 502, a second movable plate 503, a fourth fixed post 504, and a collar 505. The first movable plate 502 is slidably connected to the bottom of the fixed plate 306. The pull rope 501 is fixedly connected to the front of the first movable plate 502, and a spring is sleeved on the circumferential surface of the pull rope 501. The second movable plate 503 is fixedly connected to the rear of the first movable plate 502. The fourth fixed post 504 is fixedly connected to the bottom of the fixed plate 306, and the collar 505 is inserted into the inner wall of the fourth fixed post 504. This allows for the replacement and inspection of the fire extinguisher 2. The structure is simple, with few potential failure points, making maintenance and replacement easier for staff and ensuring that all staff can perform maintenance and replacement of the fire extinguisher 2.
[0045] The locking mechanism 5 also includes a locking box 506, an inclined block 507, a second elastic telescopic rod 508, a pressure block 509, and a second rotating plate 510. The locking box 506 is fixedly connected to the bottom of the fixed plate 306, the inclined block 507 is fixedly connected to the inner wall of the locking box 506, the fixed end of the second elastic telescopic rod 508 is fixedly connected to the inner wall of the locking box 506, the pressure block 509 is fixedly connected to the telescopic end of the second elastic telescopic rod 508, and the second rotating plate 510 is rotatably connected to the rear of the second moving plate 503.
[0046] The collar 505 is sleeved with the fire extinguisher 2, the movable plate 2 503 is in contact with the fixed column 4 504, the movable plate 2 503 is in contact with the collar 505, the movable plate 2 503 is in contact with the locking box 506, the inclined block 507 is located on the movement trajectory of the rotating plate 2 510, and the pressure block 509 is located on the movement trajectory of the rotating plate 2 510. At the same time, the rotating plate 2 510 can be better fixed to prevent the movable plate 2 503 from moving out of the locking box 506 and falling off due to shaking during the movement of the device, thus avoiding safety accidents from the source and reducing the failure rate.
[0047] Working principle: When the device moves towards one side of track 1, as it approaches that side, the sliding plate 302 first contacts the second slider 407. As the sliding plate 302 continues to move, it presses the second slider 407 towards the end closer to track 1. The movement of the second slider 407 causes the connecting rod 408 to rotate, which in turn causes the first slider 405 to move. The first slider 405 moves away from the fixed post 406 to one side, and this movement does not affect the rotation of the cam 401. At this point, the cam 401 contacts the arc plate 403. Due to the limiting effect of the arc surface of the arc plate 403, the cam 401... Rotation occurs when cam 401 is located in the middle of the arc surface of arc plate 403, and slider 405 is located to the left of cam 401. When the device moves towards the middle of track 1, the spring on fixed column 406 resets the slider 405 to the side closer to fixed column 406. Slider 405 moves to contact elastic telescopic plate 402, which in turn moves elastic telescopic plate 402 up along the arc surface. When the device moves to one end, it rotates, thus enabling detection on both sides of the device, expanding the monitoring range of the equipment, achieving full coverage of the equipment, avoiding detection errors caused by angle offset and obstruction, and greatly improving the efficiency of prevention and control monitoring.
[0048] When slider 2 407 moves closer to track 1, it presses against moving block 410, causing moving block 410 to move closer to track 1. When moving block 410 contacts rotating plate 1 412, the protrusions on the surface of rotating plate 1 412 lock moving block 410 in place. When slider 2 407 moves towards the middle of track 1, slider 1 405 moves back closer to slider 2 407, contacting rotating plate 1 412, causing rotating plate 1 412 to rotate. When the locking of the moving block 410 is released, the moving block 410 moves towards the slider 407 due to the spring return action of the elastic telescopic rod 411. At this time, the moving block 410 contacts the rotating elastic telescopic plate 402, which allows the elastic telescopic plate 402 to rotate and reset more quickly, extending the equipment life. Applying a moving thrust during rotation can achieve continuous reciprocating motion without interruption, preventing the device from failing to reset accurately due to insufficient rotational force during rotation, which would lead to a decrease in monitoring effect. This ensures that the device always maintains an accurate position for monitoring and reduces the equipment failure rate.
[0049] When the device needs to replace and inspect the fire extinguisher 2, the staff pulls the pull rope 501. The movement of the pull rope 501 moves the first moving plate 502, which in turn moves the second moving plate 503. When the second moving plate 503 moves out of the fourth fixed column 504, the fourth fixed column 504 contacts and locks the collar 505. The collar 505 then falls out of the fourth fixed column 504, allowing the fire extinguisher 2 to be replaced and inspected. The device has a simple structure and few points of failure, making it faster for staff to inspect and replace the fire extinguisher 2. This ensures that all staff can inspect and replace the fire extinguisher 2.
[0050] When the second movable plate 503 moves to the inner wall of the locking box 506, the movement of the locking box 506 drives the second rotating plate 510 to move. The second rotating plate 510 contacts the inclined block 507. Due to the inclined surface of the inclined block 507, the second rotating plate 510 rotates during its movement. During the rotation of the second rotating plate 510, the second elastic telescopic rod 508 presses against the second rotating plate 510. Due to the spring return action of the second elastic telescopic rod 508, the pressure block 509 can better fix the second rotating plate 510, preventing the second movable plate 503 from moving out of the locking box 506 and falling off during the movement of the device, thus avoiding safety accidents from the source and reducing the failure rate.
