[0026] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: A mine-use intrinsically safe infrared thermal imager, see Figures 1 to 4A protective box 11 is fixedly installed on the top surface of the fixed base 1, and a bearing base 12 is slidably installed on the inside of the protective box 11. Support plates 13 are fixedly installed on both sides of the top surface of the bearing base 12, and a thermal imager body 14 is fixedly installed on the top surface of the support plate 13. The first hollow frame 2 and the second hollow frame 21 are vertically fixedly installed in the middle of the outer side of the protective box 11, and the number of the first hollow frame 2 is three groups. A lifting mechanism is provided inside the first hollow frame 2 and the second hollow frame 21, and the lifting mechanism is transmission-connected to the bearing base 12. A synchronization mechanism is provided inside the fixed base 1, and the synchronization mechanism is transmission-connected to the lifting mechanism. Rotating rods 15 are rotatably installed at both ends of the top of the inner side of the protective box 11 through bearings, and a protective baffle 16 is sleeved on the outside of each rotating rod 15, and the protective baffle 16 is rotatably embedded in the inner side of the top of the protective box 11, and both ends of the outer side of the protective box 11 are A fixed frame 17 is fixedly installed, a follower mechanism is provided inside the fixed frame 17, a pushing mechanism is provided on the outside of the second hollow frame 21, and the pushing mechanism and the follower mechanism are connected in transmission. The lifting and lowering adjustment processing of the supporting base 12 is performed by the lifting mechanism, and under the synchronous driving action of the synchronization mechanism, combined with the mutual cooperation of the follower mechanism and the pushing mechanism, the supporting base 12 can drive the thermal imager body 14 to automatically and stably move out of or into the protective box 11. At the same time, the protective baffle 16 can automatically rotate relative to or towards the top of the protective box 11 to open and close as the supporting base 12 moves vertically, so as to use or protect the thermal imager body 14, reduce the operator's required operating steps and labor consumption for protecting or monitoring the thermal imager body 14, and improve the overall protection of the thermal imager and extend its service life.

[0028] For details, see Figures 1 to 4 The follower mechanism includes a follower gear 28. The side surface of each rotating rod 15 is fixedly sleeved with a follower gear 28, and the follower gear 28 is rotatably installed inside the fixed frame 17. A movable groove 4 is opened inside the two ends of the side of each fixed frame 17. Through the rotation connection of the follower gear 28 to the rotating rod 15, the follower gear 28 can drive the rotating rod 15 and the protective baffle 16 to rotate synchronously when it is rotated by meshing transmission to adjust the position.

[0029] For further information, see Figures 1 to 4The pushing mechanism includes a connecting plate 26 and a transmission rack 27. The sliding plates 24 are slidably fitted on the outer surface of the second hollow frame 21 at both ends. A transmission frame 25 is fixedly installed on the outer surface of each sliding plate 24 laterally. A limited sliding groove 41 is vertically provided inside the two ends of the side of the second hollow frame 21, and the transmission frame 25 passes through and is slidably inserted into the inner surface of the limited sliding groove 41. Each transmission frame 25 is vertically fixed with a connecting plate 26 on the side away from the sliding plate 24. A transmission rack 27 is fixedly installed on the top surface of each connecting plate 26. The transmission rack 27 passes through and is slidably inserted into the movable groove 4, and the outer side of the transmission rack 27 is meshed with the outer side of the follower gear 28. Through the meshing transmission action of the transmission gear and the follower gear 28, the protective baffle 16 can be rotated and adjusted synchronously with the vertical movement of the supporting base 12 and the thermal imager body 14, thereby improving the linkage between different components of the overall mechanism.

[0030] It is worth noting that, see Figures 1 to 4 The lifting mechanism includes a rotating screw 22. The first hollow frame 2 and the second hollow frame 21 are both vertically rotatably installed with a rotating screw 22 through a bearing. The outside of each rotating screw 22 is movably sleeved with a lifting sleeve 23 through a thread. A connecting rod 29 is fixedly installed on the side of each lifting sleeve 23, and the side of the connecting rod 29 is fixedly connected to the outside of the supporting base 12. The first hollow frame 2 and the second hollow frame 21 are both vertically provided with a sliding groove 42 at the middle end of the side close to the protective box 11, and the connecting rod 29 is slidably inserted into the sliding groove 42. Under the rotation transmission action of the rotating screw 22 on the lifting sleeve 23, and the connection transmission action of the connecting rod 29, the vertical movement of the supporting base 12 can be driven and adjusted from the four sides of the supporting base 12, thereby improving the movement stability of the supporting base 12 and the thermal imager body 14.

[0031] It is worth noting that see Figures 1 to 4 The synchronous mechanism includes a transmission sprocket 34, a follower sprocket 31 and a transmission chain 35. The bottom surface of each rotating screw rod 22 is vertically fixed with a movable rod 3, and the movable rod 3 extends to the inside of the fixed base 1 through a bearing. The bottom surface of each movable rod 3 is fixedly sleeved with a transmission sprocket 34, and the top side surface of the fixed base 1 is fixedly mounted with a servo motor 32. The bottom of the servo motor 32 transmission shaft is fixedly mounted with a fixed rod 33 through a coupling, and the bottom outer surface of the fixed rod 33 is fixedly mounted with a transmission sprocket 34. The transmission chain 35 is meshed and sleeved between the transmission sprocket 34 and the outer side of the follower sprocket 31. Under the meshing transmission action of the transmission chain 35 on the transmission sprocket 34 and the follower sprocket 31, the operator only needs to drive and adjust the forward and reverse rotation of the servo motor 32 to achieve the storage protection and removal and use control of the thermal imager body 14.

[0032] It is worth mentioning that see Figures 1 to 4A guide slider 5 is vertically fixedly installed at the middle end of the side of each transmission rack 27, and a guide slot 51 is vertically opened on the inner side of each fixed frame 17, and the guide slider 5 is slidably inserted into the guide slot 51. Under the guiding sliding action of the guide slot 51 on the guide slider 5, the transmission rack 27 can only move vertically inside the fixed frame 17 after being pushed and pulled, and will not move laterally tilted, thereby ensuring the transmission rationality of the entire mechanism.

[0033] During operation, when it is necessary to store and protect the thermal imager body 14 located on the top outside of the protective box 11, the servo motor 32 is turned on by the external control switch to make it run and drive the movable rod 3 and the transmission sprocket 34 sleeved on its surface to rotate synchronously in the opposite direction inside the fixed base 1. Combined with the meshing transmission action of the transmission chain 35 on the transmission sprocket 34 and the follower sprocket 31, it can drive multiple groups of follower sprockets 31 to connect the movable rods 3 vertically arranged inside thereof to rotate synchronously and in the same direction, and then, under the connection transmission action of the movable rod 3, it can drive the movable rods 3 located in the protective box 1. 1, the rotating screws 22 inside the first hollow frame 2 and the second hollow frame 21 outside rotate synchronously and in the same direction. Combined with the rotation transmission effect of the rotating screws 22 on the lifting sleeves 23, and the guiding and limiting effect of the sliding grooves 42 on the connecting rods 29, the four groups of lifting sleeves 23 can be synchronously and in the same direction descended vertically outside the protective box 11, thereby driving the supporting base 12 and the thermal imager body 14 to synchronously descend vertically toward the inside of the protective box 11. At the same time, under the connecting transmission effect of the sliding plate 24, the lifting sleeves 23 can be synchronously lowered when vertically descending. The transmission frame 25 and the connecting plate 26 and the transmission rack 27 vertically arranged on the side thereof are synchronously vertically lowered, so that when the connecting plate 26 and the transmission rack 27 pass through the movable slot 4 and vertically descend inside the fixed frame 17, the meshing transmission action of the transmission rack 27 and the follower gear 28 can drive the follower gear 28 and the rotating rod 15 sleeved therein to rotate synchronously, thereby driving the protective baffles 16 on both sides of the top of the protective box 11 to rotate synchronously with each other as the thermal imager body 14 continues to descend inside the protective box 11, until the protective baffles 16 are completely inserted. After being embedded in the top of the protective box 11, the protective box 11 and the protective baffle 16 are combined to realize the protection treatment of the thermal imager body 14. When the thermal imager body 14 needs to be used, the servo motor 32 is turned on by the external control switch, so that it drives the transmission sprocket 34 to rotate synchronously in the positive direction inside the fixed base 1, and the above operation steps are repeated, so that the thermal imager body 14 is automatically lifted and moved out of the protective box 11, and the mining equipment outside the protective box 11 is monitored for heat sources to avoid the operating temperature of the mining machinery and equipment being too high and affecting the mining efficiency of the ore.
