Description

Technical Field

[0001] The invention relates to the technical field of mine traffic control equipment, and in particular to a mine traffic signal control device and a control method. Background Art

[0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. Inclined shafts, vertical shafts, horizontal shafts, etc. in underground mine development are sometimes also called mines. Due to the intricate laying of rails in the mine, in order to avoid danger when the mine car is moving, a traffic signal control device is installed in the mine to control the mine car. At present, most of the traffic signal control devices used in mines are traffic lights. However, since it is more troublesome to lay circuits in mines, some traffic lights are usually directly powered by batteries. However, since the power stored in batteries is fixed, it is easy for traffic lights to stop working due to battery exhaustion during use, affecting normal traffic control. In addition, due to being underground, the lower temperature will also affect the battery life, thereby affecting the service life of traffic lights. For this reason, we propose a traffic signal control device and control method for mines. Summary of the invention

When the rack moves, the large gear can be controlled to rotate back and forth, and the large gear drives the small gear to rotate back and forth. Since the diameter of the large gear is larger than that of the small gear, the speed of the small gear is faster than that of the large gear, and the small gear drives the generator to rotate, thereby realizing the power generation operation, and the energy generated by the generator is stored in the battery equipment, so as to improve the endurance of the signal light body.

When the rack moves downward, in order to drive the large gear to rotate clockwise, the large gear drives the small gear to rotate counterclockwise, and the small gear drives the output shaft of the generator to rotate counterclockwise. At this time, the pawl on the surface of the output shaft of the generator can be stuck on the ratchet on the inner side of the circular ring to drive the circular ring to rotate counterclockwise together. At this time, the limiting rod is in a state of being inserted in the annular clamping tooth on the surface of the circular ring. When the circular ring rotates counterclockwise, the annular clamping tooth contacts the limiting rod, so that the limiting rod swings to the side away from the fixing block at the position hinged with the connecting rod, and at the same time the circular ring winds up the volute spring. When the rack is in the reset spring When the gear is fully reset, the lever on the side of the gear rack close to the ring can contact the connecting rod and push the connecting rod to move upward a certain distance, and the connecting rod moves upward with the limiting rod, so that the limiting rod is no longer stuck in the annular teeth on the surface of the ring, thereby releasing the limit of the ring, and under the action of the spiral spring, the ring rotates clockwise, and the ratchet on the inner side of the ring is stuck on the ratchet on the surface of the generator output shaft, thereby driving the output shaft of the generator to rotate clockwise, so that the generator starts to work to charge the battery equipment, further improving the endurance of the signal light body.

[0009] Preferably, the driven component includes a friction ring, which is fixed on the inner wall of the signal light body, an auxiliary ring is fixed on the side of the circular ring away from the generator, and the auxiliary ring passes through the column and the signal light body. A connecting ring is rotatably installed on the inner wall of the friction ring, and an L-shaped friction rod is fixed on the surface of the connecting ring. The inner wall of the friction ring is provided with a spiral groove and an annular groove, and the surface of the L-shaped friction rod is provided with a movable groove, and a slider is slidably installed on the inner side of the movable groove, and a rubber rope is fixed on the inner side of the movable groove, and one end of the rubber rope away from the movable groove is fixed to the slider, one end of the slider is inserted into the inner side of the spiral groove, and the other end of the slider is slidably installed on the surface of the L-shaped clamping rod, and the L-shaped clamping rod is slidably installed on the surface of the L-shaped friction rod. , the spiral groove and the annular groove are connected, an inclined block is fixed on the inner side of the spiral groove, a resistance rod is slidably installed on the surface of the L-shaped friction rod, the connecting ring is penetrated by the resistance block and is slidably connected with the resistance block, a spring 2 is fixed on the surface of the connecting ring, one end of the spring 2 away from the connecting ring is fixed to the resistance block, a rubber splint is fixed on the side of the resistance block close to the center of the connecting ring, a ratchet 2 is arranged on the inner side of the connecting ring, a ratchet 2 is arranged on the surface of the auxiliary ring, a rotating rod is rotatably installed on the inner wall of the friction ring, the rotating rod penetrates the limiting tooth ring and is fixedly connected to the limiting tooth ring, the rotating rod penetrates the fan blade and is fixedly connected to the fan blade, the end of the L-shaped friction rod close to the connecting ring is set to a retractable state, and a square hole is opened on the slider, A fixing rod is fixed on the surface of the L-shaped clamping rod, and the fixing rod penetrates the rubber ball and is fixed to the rubber ball. When the circular ring rotates, the circular ring drives the auxiliary ring to rotate. At this time, since the rubber clamping plate abuts against the surface of the auxiliary ring, the auxiliary ring can drive the connecting ring to rotate through the rubber clamping plate and the abutment block. The connecting ring drives the L-shaped friction rod to rotate. The friction between the L-shaped friction rod and the friction ring generates heat, so that the inside of the signal lamp body can be maintained at a certain temperature, so that the battery equipment is not affected by low temperature and the endurance of the signal lamp body in the low temperature mine is improved. As the generator charges the battery equipment, the temperature of the battery equipment increases. At this time, as the L-shaped friction rod drives the slider to rotate, the slider slides along the spiral groove on the inner wall of the friction ring. When the slider slides to the inclined block The sliding block drives the rubber splint to move together, so that the rubber splint can no longer be clamped on the surface of the auxiliary ring.The circular ring drives the auxiliary ring to rotate counterclockwise, and the ratchet wheel 2 on the surface of the auxiliary ring is stuck on the pawl 2 on the inner side of the connecting ring, thereby driving the connecting ring to rotate together. At this time, the connecting ring drives the limit tooth ring and the rotating rod to rotate through the L-shaped friction rod and the L-shaped clamping rod, and the rotating rod drives the fan blades to rotate, so as to discharge the hot air in the signal light body to the column, thereby avoiding the internal temperature of the signal light body being too high and causing damage to the battery equipment. When the auxiliary ring rotates clockwise, the ratchet wheel 2 on the surface of the auxiliary ring cannot be stuck on the pawl 2, so that the connecting ring cannot rotate together, thereby preventing the fan blades from rotating and drawing back the hot air just discharged. When the car continues to pass, the L-shaped friction rod can keep rotating counterclockwise, and the rubber ball can keep the slider in the annular groove. When the auxiliary ring stops rotating, the slider gradually moves to the left and resets under the action of the rubber rope. When the slider is completely separated from the rubber ball, the slider is pulled and slides back into the spiral groove to achieve reset. After the slider is reset, the resistance rod is no longer resisted. The resistance block drives the rubber clamp to reset under the action of spring 2. At the same time, after the slider is reset, the slider is no longer resisted by the inclined block. The slider drives the L-shaped clamping rod to reset, so that the L-shaped clamping rod can no longer be stuck on the limit tooth ring, thereby achieving the reset of the device.

[0010] Preferably, a sealing bearing is provided at the position where the connecting ring is connected to the signal lamp body, so as to ensure the sealing of the signal lamp body without affecting the rotation of the connecting ring.

[0011] Preferably, the battery device is electrically connected to the signal light body, and the signal light body is powered by the battery device to ensure the normal operation of the signal light body.

[0012] The present invention also provides a mine traffic signal control method, which is applied to the above-mentioned mine traffic signal control device, and comprises the following steps:

[0013] S1. Install the signal light body and the column at the designated position of the rail by bolts, display the signal light through the predetermined program of the signal light body, and control the traffic signal in the mine;

[0014] S2. Whenever a mine car passes the pillar, the tire of the mine car contacts the arc block, pushing the arc block to move downward. When the mine car passes, the arc block is no longer contacted. Under the action of the reset spring, the arc block and the rack move upward, thereby controlling the rack to move up and down. When the rack moves downward, the rack drives the lever to move downward together, and the lever no longer contacts the connecting rod. Under the action of the connecting spring, the connecting rod moves downward with the limit rod, and the limit rod is inserted into the annular tooth on the surface of the ring. Even if the limit rod is not inserted immediately, as the ring rotates, the limit rod will be inserted into the annular tooth later.

[0015] S3. When the rack moves downward, it drives the large gear to rotate clockwise, the large gear drives the small gear to rotate counterclockwise, the small gear drives the output shaft of the generator to rotate counterclockwise, the generator works to supply power to the battery device, so that the battery device stores electrical energy;

[0016] S4. When the output shaft of the generator rotates counterclockwise, the pawl 1 on the surface of the generator output shaft is clamped on the ratchet 1 on the inner side of the ring, driving the ring to rotate counterclockwise. At this time, the annular clamping teeth on the surface of the ring abut against the limit rod, so that the limit rod swings to the side away from the fixed block at the position hinged with the connecting rod, which will not affect the normal counterclockwise rotation of the ring. At this time, the ring winds up the volute spring;

[0017] S5. When the rack moves upward, the rack drives the large gear to rotate counterclockwise, and the small gear and the output shaft of the generator rotate clockwise at this time. At this time, the pawl 1 on the surface of the generator output shaft cannot be stuck on the ratchet 1 on the inner side of the ring, and thus will not drive the ring to rotate clockwise together. At the same time, the annular clamping tooth on the surface of the ring is resisted by the limit rod, and the ring cannot rotate clockwise under the action of the volute spring. When the rack is completely reset, the lever on the rack resists on the connecting rod and pushes the connecting rod to move upward a certain distance. The connecting rod drives the limit rod to move upward together, and the limit rod is no longer stuck in the annular clamping tooth, so that the limit on the ring is released. Under the action of the volute spring, the ring rotates clockwise. At this time, the ratchet 1 on the inner side of the ring is stuck on the pawl 1 on the surface of the generator output shaft, driving the generator to rotate clockwise together, so that the generator works again to charge the battery equipment;

[0018] S6. As the circular ring rotates, the circular ring drives the auxiliary ring to rotate. At this time, the rubber splint contacts the surface of the auxiliary ring, so that the auxiliary ring can drive the connecting ring to rotate through the rubber splint and the contact block. The connecting ring drives the L-shaped friction rod to rotate. The friction between the L-shaped friction rod and the friction ring generates heat, so that the inside of the signal light body can be kept at a certain temperature, so that the battery equipment is not affected by low temperature and the endurance of the signal light body in the low temperature mine is improved. As the generator charges the battery equipment, the temperature of the battery equipment increases. At this time, as the L-shaped friction rod drives the slider to rotate, the slider slides along the spiral groove on the inner wall of the friction ring. When the slider slides to the inclined When the face block is in the position, the slider is in the annular groove. At this time, the rubber ball is squeezed and deformed and passes through the square hole on the slider to limit the slider to a certain extent. The slider moves the L-shaped friction rod to the side close to the center of the connecting ring, so that the L-shaped friction rod no longer contacts the inner wall of the friction ring. At the same time, the slider pushes the L-shaped clamping rod to move together, so that the L-shaped clamping rod is clamped on the limiting gear ring, thereby driving the limiting gear ring to rotate together, and the limiting gear ring drives the rotating rod and the fan blades to rotate. At the same time, the slider abuts on the resistance rod and pushes the resistance rod to move to the right. The resistance rod abuts on the inclined surface of the resistance block and pushes the resistance block to move to the side away from the center of the connecting ring. The resistance block drives the rubber splint. When the auxiliary ring rotates clockwise, the ratchet wheel 2 on the surface of the auxiliary ring cannot be stuck on the pawl 2 on the inner side of the connecting ring, thereby driving the connecting ring to rotate together. At this time, the connecting ring drives the limit tooth ring and the rotating rod to rotate through the L-shaped friction rod and the L-shaped clamping rod, and the rotating rod drives the fan blades to rotate, thereby discharging the hot air in the signal light body to the column for discharge, avoiding the internal temperature of the signal light body being too high and causing damage to the battery equipment. When the auxiliary ring rotates clockwise, the ratchet wheel 2 on the surface of the auxiliary ring cannot be stuck on the pawl 2, thereby preventing the connecting ring from rotating together, thereby preventing the fan blades from rotating. , and the hot air just discharged is drawn back. When the mine car continues to pass by, the L-shaped friction rod can keep rotating counterclockwise, and the rubber ball can keep the slider in the annular groove. When the auxiliary ring stops rotating, the slider gradually moves to the left and resets under the action of the rubber rope. When the slider is completely separated from the rubber ball, the slider is pulled and slides back into the spiral groove, thereby resetting. After the slider is reset, the resistance rod is no longer resisted, and the resistance block drives the rubber splint to reset under the action of spring 2. At the same time, after the slider is reset, the slider is no longer resisted by the inclined block, and the slider drives the L-shaped clamping rod to reset, so that the L-shaped clamping rod can no longer be stuck on the limit tooth ring, thereby resetting the device.

[0019] Compared with the prior art, the present invention provides a traffic signal control device and control method for underground mines, which have the following beneficial effects:

[0020] 1. When the mine car moves to the position of the arc block, the wheels of the mine car contact the arc block and push the arc block downward. When the arc block is no longer contacted by the wheels of the mine car, the rack can move the arc block upward and reset under the action of the reset spring. As the mine car moves, the arc block and the rack can move up and down. When the rack moves, the large gear can be controlled to rotate back and forth, and the large gear drives the small gear to rotate back and forth. Since the diameter of the large gear is larger than the small gear, the speed of the small gear is faster than the large gear. The small gear drives the generator to rotate, thereby realizing the power generation operation. The energy generated by the generator is stored in the battery equipment to improve the endurance of the signal light body.

[0021] 2. When the rack moves downward, the output shaft of the generator is controlled to rotate counterclockwise, so that the generator starts to work. When the rack is completely reset, the lever on the side of the rack close to the ring can contact the connecting rod and push the connecting rod upward for a certain distance. The connecting rod moves upward with the limit rod, so that the limit rod is no longer stuck in the annular teeth on the surface of the ring, thereby releasing the limit on the ring. Under the action of the volute spring, the ring rotates clockwise. At this time, the ratchet on the inner side of the ring is stuck on the pawl on the surface of the generator output shaft, thereby driving the output shaft of the generator to rotate clockwise, so that the generator starts to work to charge the battery equipment, further improving the endurance of the signal light body.

[0022] 3. When the circular ring rotates, the circular ring drives the auxiliary ring to rotate. At this time, the rubber splint contacts the surface of the auxiliary ring, so that the auxiliary ring can drive the connecting ring to rotate through the rubber splint and the contact block. The connecting ring drives the L-shaped friction rod to rotate. The L-shaped friction rod and the friction ring generate heat by friction, so that the inside of the signal light body can be maintained at a certain temperature, so that the battery equipment can avoid the impact of low temperature on the endurance, and improve the endurance of the signal light body in low temperatures in mines.

[0023] 4. During the charging process, the temperature of the battery device increases. After the slider slides into the annular groove, the L-shaped friction rod can be controlled to no longer contact the inner wall of the friction ring. At the same time, the fan blades can be controlled to rotate to discharge the hot air in the signal light body to the column, avoiding excessive temperature inside the signal light body and causing damage to the battery device.

When the car moves to the position of the arc block 32, the wheels of the mine car contact the arc block 32 and push the arc block 32 downward. When the arc block 32 is no longer contacted by the wheels of the mine car, the rack 33 can move the arc block 32 upward and reset under the action of the reset spring 37. As the mine car moves forward, the arc block 32 and the rack 33 move up and down. When the rack 33 moves, the large gear 34 can be controlled to rotate back and forth, and the large gear 34 drives the small gear 35 to rotate back and forth. Since the diameter of the large gear 34 is larger than that of the small gear 35, the speed of the small gear 35 is faster than that of the large gear 34. The small gear 35 drives the generator 36 to rotate, thereby realizing the power generation operation. The energy generated by the generator 36 is stored in the battery device 2, thereby improving the endurance of the signal light body 1.

[0039] The driven device 4 includes a circular ring 41, which is rotatably mounted on the inner wall of the column 31, a spiral spring 42 is fixed on the surface of the circular ring 41, and the end of the spiral spring 42 away from the circular ring 41 is fixed to the inner side of a fixing ring 43, and the fixing ring 43 is fixed to the inner wall of the column 31. A ratchet 44 is provided on the inner side of the circular ring 41, a pawl 45 is provided on the surface of the output shaft of the generator 36, and an annular clamping tooth 46 is fixed on the surface of the circular ring 41. A connecting rod 47 is slidably mounted on the inner wall of the column 31, a connecting spring 48 is fixed on the top of the connecting rod 47, and the end of the connecting spring 48 away from the connecting rod 47 is fixed to the inner wall of the column 31, and a lever 49 is fixed to the side of the rack 33 close to the circular ring 41 The bottom of the connecting rod 47 is hinged with a limit rod 410, one side of the connecting rod 47 is fixed with a torsion spring 411, and the other side of the connecting rod 47 is fixed with a fixing block 412. The end of the torsion spring 411 away from the connecting rod 47 is fixed to the limit rod 410.

At this time, the pawl 45 on the surface of the output shaft of the generator 36 can be stuck on the ratchet 44 on the inner side of the ring 41 to drive the ring 41 to rotate counterclockwise. At this time, the limit rod 410 is inserted into the annular tooth 46 on the surface of the ring 41. The ring 41 rotates counterclockwise.

At the same time, the annular tooth 46 on the surface of the ring 41 is contacted by the limit rod 410, and the ring 41 cannot rotate clockwise under the action of the spiral spring 42. After fully resetting, the lever 49 on the side of the rack 33 close to the ring 41 can abut against the connecting rod 47 and push the connecting rod 47 to move upward a certain distance. The connecting rod 47 moves upward together with the limiting rod 410, so that the limiting rod 410 is no longer stuck in the annular tooth 46 on the surface of the ring 41, thereby releasing the limit on the ring 41. Under the action of the spiral spring 42, the ring 41 rotates clockwise. At this time, the ratchet 44 on the inner side of the ring 41 is stuck on the pawl 45 on the surface of the output shaft of the generator 36, thereby driving the output shaft of the generator 36 to rotate clockwise, so that the generator 36 starts to work to charge the battery device 2, thereby further improving the endurance of the signal lamp body 1.

As the generator 36 charges the battery device 2, the temperature of the battery device 2 increases. At this time, as the L-shaped friction rod 53 drives the slider 56 to rotate, the slider 56 slides along the spiral groove 54 on the inner wall of the friction ring 51. When the slider 56 slides to the position of the inclined block 511, the slider 56 is in the annular groove 510. At this time, the rubber ball 524 is squeezed and deformed and passes through the square hole 522 on the slider 56 to limit the slider 56 to a certain extent. The slider 56 moves with the L-shaped friction rod 53 to the side close to the center of the connecting ring 52.The L-shaped friction rod 53 is no longer in contact with the inner wall of the friction ring 51, and the slider 56 pushes the L-shaped clamping rod 58 to move together, so that the L-shaped clamping rod 58 is clamped on the limiting toothed ring 520, thereby driving the limiting toothed ring 520 to rotate together, and the limiting toothed ring 520 drives the rotating rod 519 and the fan blade 521 to rotate. At the same time, the slider 56 abuts on the resistance rod 513 and pushes the resistance rod 513 to move rightward. The resistance rod 513 abuts on the inclined surface of the resistance block 514 and pushes the resistance block 514 to move to the side away from the center of the connecting ring 52. The resistance block 514 drives the rubber The rubber clamping plate 516 moves together, so that the rubber clamping plate 516 can no longer be clamped on the surface of the auxiliary ring 512. When the circular ring 41 rotates counterclockwise, the circular ring 41 drives the auxiliary ring 512 to rotate counterclockwise. The ratchet 518 on the surface of the auxiliary ring 512 is clamped on the ratchet 517 on the inner side of the connecting ring 52, thereby driving the connecting ring 52 to rotate together.

[0041] A sealing bearing 6 is provided at the position where the connecting ring 52 is connected to the signal lamp body 1 , so as to ensure the sealing of the signal lamp body 1 without affecting the rotation of the connecting ring 52 .

[0042] The battery device 2 is electrically connected to the signal light body 1 , and the signal light body 1 is powered by the battery device 2 to ensure the normal operation of the signal light body 1 .

[0043] It is worth noting that the generator 36 in the present application is an existing device, and the circuit connection between the generator 36 and the battery device 2 is also an existing public technology. The working principle of the generator 36 is based on the law of electromagnetic induction and the law of electromagnetic force, and uses magnetic field induction to generate electromotive force, thereby converting mechanical energy into electrical energy. Specifically, the generator 36 is driven by a prime mover such as a turbine, a steam turbine, a diesel engine, etc. to rotate the rotor, so that the excitation magnetic field rotates with the shaft and sequentially cuts the stator windings of each phase, thereby generating an alternating electromotive force in the stator winding. This process is to generate an induced electromotive force in the conductor by cutting the magnetic flux lines in the magnetic field. When the induced electromotive force reaches a certain value, the AC current can be output through the lead wire. In addition, the basic components of the generator 36 include a prime mover, a rotor, and a stator. The prime mover provides energy to drive the rotor to rotate, and the rotor uses residual magnetism or direct current to generate a magnetic field. When the rotor rotates, a relative cutting magnetic flux line movement is formed for the stator, thereby generating an induced electromotive force on the stator. If the stator and the external circuit are connected to form a closed circuit, current will be output to the load, but it is not the main innovative part of this application, so it is not elaborated in this application.

[0044] The present invention also provides a mine traffic signal control method, which is applied to the above-mentioned mine traffic signal control device, and comprises the following steps:

[0045] S1, installing the signal light body 1 and the column 31 at the designated position of the rail by bolts, and performing signal light display through the predetermined program of the signal light body 1 to control the traffic signal in the mine;

[0046] S2. Whenever a mine car passes the column 31, the tire of the mine car contacts the arc block 32, pushing the arc block 32 to move downward. When the mine car passes through, the arc block 32 is no longer contacted. Under the action of the return spring 37, the arc block 32 and the rack 33 move upward, thereby controlling the rack 33 to move back and forth. When the rack 33 moves downward, the rack 33 drives the lever 49 to move downward together. The lever 49 no longer contacts the connecting rod 47. Under the action of the connecting spring 48, the connecting rod 47 moves downward with the limiting rod 410. The limiting rod 410 is inserted into the annular tooth 46 on the surface of the ring 41. Even if the limiting rod 410 is not inserted immediately, as the ring 41 rotates, the limiting rod 410 will be inserted into the annular tooth 46 later.

[0047] S3, when the rack 33 moves downward, it drives the large gear 34 to rotate clockwise, the large gear 34 drives the small gear 35 to rotate counterclockwise, the small gear 35 drives the output shaft of the generator 36 to rotate counterclockwise, the generator 36 works to supply power to the battery device 2, so that the battery device 2 stores electrical energy;

[0048] S4. When the output shaft of the generator 36 rotates counterclockwise, the pawl 45 on the surface of the output shaft of the generator 36 is clamped on the ratchet 44 on the inner side of the ring 41, driving the ring 41 to rotate counterclockwise together. At this time, the annular clamping teeth 46 on the surface of the ring 41 abut against the limit rod 410, so that the limit rod 410 swings to the side away from the fixed block 412 at the position hinged with the connecting rod 47, which will not affect the normal counterclockwise rotation of the ring 41. At this time, the ring 41 winds up the spiral spring 42.

[0049] S5. When the rack 33 moves upward, the rack 33 drives the large gear 34 to rotate counterclockwise, and the small gear 35 and the output shaft of the generator 36 rotate clockwise. At this time, the pawl 45 on the surface of the output shaft of the generator 36 cannot be stuck on the ratchet 44 on the inner side of the ring 41, and thus the ring 41 will not be driven to rotate clockwise. At the same time, the annular tooth 46 on the surface of the ring 41 is resisted by the limit rod 410, and the ring 41 cannot rotate clockwise under the action of the spiral spring 42. When the rack 33 is completely reset, the rack 33 The lever 49 on the upper part abuts against the connecting rod 47 and pushes the connecting rod 47 to move upward a certain distance, and the connecting rod 47 drives the limiting rod 410 to move upward together, and the limiting rod 410 is no longer stuck in the annular clamping tooth 46, so that the limit of the ring 41 is released. Under the action of the spiral spring 42, the ring 41 rotates clockwise. At this time, the ratchet 44 on the inner side of the ring 41 is stuck on the pawl 45 on the surface of the output shaft of the generator 36, driving the generator 36 to rotate clockwise together, so that the generator 36 works again to charge the battery device 2;

[0050] S6. As the circular ring 41 rotates, the circular ring 41 drives the auxiliary ring 512 to rotate. At this time, since the rubber clamp 516 contacts the surface of the auxiliary ring 512, the auxiliary ring 512 can drive the connecting ring 52 to rotate through the rubber clamp 516 and the contact block 514. The connecting ring 52 drives the L-shaped friction rod 53 to rotate. The L-shaped friction rod 53 and the friction ring 51 rub to generate heat, so that the inside of the signal light body 1 can be kept at a certain temperature, so that the battery device 2 is not affected by low temperature and the endurance of the signal light body 1 in the low temperature mine is improved. As the generator 36 charges the battery device 2, the temperature of the battery device 2 increases. At this time, as the L-shaped friction rod 53 drives the slider 56 to rotate, the slider 56 moves along the inner wall of the friction ring 51. The spiral groove 54 slides, and when the slider 56 slides to the position of the inclined block 511, the slider 56 is in the annular groove 510. At this time, the rubber ball 524 is squeezed and deformed and passes through the square hole 522 on the slider 56 to limit the slider 56 to a certain extent. The slider 56 moves with the L-shaped friction rod 53 to the side close to the center of the connecting ring 52, so that the L-shaped friction rod 53 no longer contacts the inner wall of the friction ring 51. At the same time, the slider 56 pushes the L-shaped clamping rod 58 to move together, so that the L-shaped clamping rod 58 is clamped on the limiting toothed ring 520, so that the limiting toothed ring 520 can be driven to rotate together. The limiting toothed ring 520 drives the rotating rod 519 and the fan blade 521 to rotate. At the same time, the slider 56 abuts on the resistance rod 513 to push the resistance rod 513 to move rightward, and the resistance rod 513 The contact rod 513 contacts the inclined surface of the contact block 514, pushing the contact block 514 to move to the side away from the center of the connecting ring 52, and the contact block 514 drives the rubber clamp 516 to move together, so that the rubber clamp 516 can no longer be clamped on the surface of the auxiliary ring 512. When the circular ring 41 rotates counterclockwise, the circular ring 41 drives the auxiliary ring 512 to rotate counterclockwise together, and the ratchet 2 518 on the surface of the auxiliary ring 512 is stuck on the ratchet 2 517 on the inner side of the connecting ring 52, thereby driving the connecting ring 52 to rotate together. At this time, the connecting ring 52 drives the limiting tooth ring 520 and the rotating rod 519 to rotate through the L-shaped friction rod 53 and the L-shaped clamping rod 58, and the rotating rod 519 drives the fan blade 521 to rotate, so as to discharge the hot air in the signal lamp body 1 to the column 31 for discharge, thereby avoiding the signal lamp from being blocked. The internal temperature of the lamp body 1 is too high, causing damage to the battery device 2. When the auxiliary ring 512 rotates clockwise, the ratchet 518 on the surface of the auxiliary ring 512 cannot be stuck on the ratchet 517, so that the connecting ring 52 cannot rotate together, thereby preventing the fan blade 521 from rotating and drawing back the hot air just discharged. When a mine car continues to pass by, the L-shaped friction rod 53 can maintain a counterclockwise rotation state, and cooperate with the rubber ball 524 to keep the slider 56 in the annular groove 510. When the auxiliary ring 512 stops rotating, under the action of the rubber rope 57, the slider 56 gradually moves to the left and resets. When the slider 56 is completely separated from the rubber ball 524, the slider 56 is pulled to slide back into the spiral groove 54, thereby achieving reset. After the slider 56 is reset,The abutment rod 513 is no longer abutted, and the abutment block 514 drives the rubber clamp 516 to reset under the action of the second spring 515. At the same time, after the slider 56 is reset, the slider 56 is no longer abutted by the inclined block 511, and the slider 56 drives the L-shaped clamping rod 58 to reset, so that the L-shaped clamping rod 58 can no longer be stuck on the limit tooth ring 520, thereby realizing the reset of the device.
