DETAILED DESCRIPTION

[0031] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0032] A specific embodiment of the present invention is as follows Figure 1 As shown, a movable infrared thermal imaging monitoring system is disclosed, which includes an infrared thermal imager 1, a mobile unit 2 and a control unit 3.

[0033] The infrared thermal imager 1 is arranged on the upper part of the mobile unit 2 through the infrared thermal imager mounting plate 6 and can move with the mobile unit 2. The control unit 3 is used to control the movement of the mobile unit 2 and the lifting and angle adjustment of the infrared thermal imager 1.

[0034] like Figure 2As shown, the infrared thermal imager 1 includes a lens 101 , an upper housing 102 , an output line waterproof connector 103 and an adjustment structure 104 .

[0035] The lens 101 of the infrared thermal imager 1 is fixed on the top of the housing 102 and can rotate with the housing 102. A waterproof connector for installing the output network cable and power cable is set on one side of the housing 102, and an adjustment structure 104 is set below the housing 102.

[0036] like Figure 3 As shown, the adjustment structure 104 includes an adapter block 1041 , a rotating shaft 1042 , a universal joint 1043 , a universal joint base 1044 and an adjustment knob 1045 .

[0037] One end of the rotating shaft 1042 has a flange, which is connected to the shell 102. The rotation of the rotating shaft 1042 can drive the shell 102 to rotate. The other end of the rotating shaft 1042 is connected to the universal joint 1043. The universal joint 1043 is a spherical structure, which is used to adjust the rotation angle of the shell 102. The universal joint 1043 is installed in the universal joint base 1044 and can rotate in the universal joint base 1044. An adjustment button 1045 is installed on one side of the universal joint base 1044. The adjustment button 1045 has a rod. The outside of the rod is threaded and can be screwed inward into the universal joint base 1044. The end abuts against the universal joint 1043, so that the universal joint 1043 is fixed. The rod is screwed outward, and the end of the rod leaves the universal joint 1043, and the universal joint 1043 can rotate.

[0038] The adapter block 1041 is disposed between the housing 102 and the flange of the rotating shaft 1042 . A threaded hole is provided inside the adapter block 1041 for adapting to thread conversion of infrared thermal imagers 1 of various specifications.

[0039] The adjustment structure 104 of the universal joint 1043 of the infrared thermal imager 1 can drive the housing 102 and the lens 101 to adjust 360 degrees to monitor multiple positions of the cabinet.

[0040] The output line waterproof connector 103 of the infrared thermal imager 1 is provided on one side of the housing 102 and is electrically connected to the control board 303 .

[0041] like Figure 4 As shown, the mobile unit 2 includes a track 203, a drag chain 202, and a timing belt 201. The track 203 provides support and guidance for the entire mobile unit 2, ensuring that the infrared thermal imager 1 can move in a predetermined direction. The control unit 3 is mounted on one end of the track 203, and the other end is mounted on the mobile unit support plate 5 and secured by the mobile unit fixing plate 501.

[0042] like Figure 5As shown, a synchronous belt 201 is installed on one side of a track 203, with its length aligned with that of the track 203. The synchronous belt 201 is mounted on pulleys 2011 at both ends of the track 203 and moves as the pulleys 2011 rotate. The side of the synchronous belt 201 that contacts the pulleys 2011 is equipped with teeth, and the pulleys 2011 have corresponding tooth grooves that mesh with the synchronous belt 201. The synchronous pulley 2011 at one end near the control unit 3 is the driving pulley, while the synchronous pulley 2011 at the other end is the driven pulley. Driven by the control unit 3, the tooth grooves of the driving pulley mesh with the teeth of the synchronous belt 201. When the driving pulley rotates, the interaction between the tooth grooves and the teeth transmits power to the synchronous belt 201. While transmitting power, the synchronous belt 201 also rotates the tooth grooves of the driven pulley, thereby driving the driven pulley as well.

[0043] A limiter 4 is provided on one side of the synchronous belt 201 for limiting the movement of the infrared thermal imager 1 .

[0044] Compared to existing technologies, the infrared thermal imager 1 of this embodiment is driven by a timing belt 201. The teeth of the timing belt 201 and the tooth grooves of the pulley maintain a constant relative position during engagement, ensuring stable and accurate transmission. Compared to guide rails and other motion methods, the timing belt 201 offers low manufacturing costs, light weight, and a simple structure, while still ensuring stable and accurate transmission.

[0045] The infrared thermal imager 1's network and power cables are secured within a drag chain 202. One end of the drag chain 202 is secured to the drag chain mounting plate 2021, and the other end is secured to the infrared thermal imager mounting plate 6. When the drive wheel rotates, the synchronous pulley 2011 transmits power to the synchronous belt 201, causing the synchronous belt 201 to move, simultaneously driving the infrared thermal imager mounting plate 6. Because the infrared thermal imager mounting plate 6 and one end of the drag chain 202 are fixed, when the infrared thermal imager mounting plate 6 moves, the drag chain 202, carrying the network and power cables of the infrared thermal imager 1, moves along with the infrared thermal imager mounting plate 6, providing the infrared thermal imager 1 with the required power and network.

[0046] like Figure 6 As shown, the control unit 3 includes a control base 301, a control power supply 302, a control board 303, a stepping motor 304, a fixing bracket 305 and a control unit housing.

[0047] The control base 301 is fixed on the guide rail by screws, the control power supply 302 and the control board 303 are fixed on the fixing bracket 305, and the fixing bracket 305 and the stepping motor 304 are installed on the fixing bottom plate.

[0048] After the control board 303 receives the position command from the infrared thermal imager 1, the control board 303 controls the stepper motor 304 to rotate and samples the code value of the stepper motor 304. When the code value of the stepper motor 304 is consistent with the received position value, the control board 303 controls the stepper motor 304 to stop moving.

[0049] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
