[0054] The end of the support rod two 51 is fixedly connected with the outer surface of the rotating plate 33, and the outer surface of the scraping plate 58 is attached to the outer surface of the scraping ring 52.

[0055] The specific working process is as follows:

[0056] When detection is needed, the mover 21 on the fixed ring plate 1 controls the roller 22 to rotate, so that the whole device moves on the outer surface of the pipeline 6, and meanwhile, the servo motor one 24 drives the rotating shaft one 25 and the gear 26 to rotate, so that the rotating plate 33 rotates along the guide ring 32, and the monitoring unit 4 is controlled to move to a specific position, in the process that the moving assembly 2 controls the whole device to move, the scraping ring 52 moves along the outer surface of the pipeline 6 and removes the waterweeds or dust on the pipeline 6, so that the dust impurities or waterweeds do not contact the monitoring unit 4, and meanwhile, in the process that the rotating plate 33 starts to rotate and stops to rotate, the sliding weight 54 slides along the inner groove 53 due to inertia, and the spiral fan blade 56 and the rotating shaft two 57 rotate due to the liquid resistance during sliding, so that the scraping plate 58 brushes the side of the scraping ring 52 from which the impurities are removed, and the dust on the side is cleaned.

[0057] In the second embodiment, the chemical pipeline 6 surface temperature monitoring device with an alarm function is used Figures 1-13 An embodiment of the present application is described as follows.

[0058] As shown in the drawings, Figures 8-9As shown, the chemical pipeline 6 surface temperature monitoring device with alarm function of the present application, based on example one, the monitoring unit 4 includes hydraulic device 41, the hydraulic device 41 is provided with telescopic end 42, the bottom of telescopic end 42 is fixedly connected with frame plate 43, the side away from hydraulic device 41 of frame plate 43 is provided with arc surface 48 with the same bending angle as pipeline 6, frame plate 43 is provided with liquid pumping machine 44, the outer surface of liquid pumping machine 44 is provided with liquid outlet pipe 45, liquid inlet pipe 46 is fixedly connected to liquid pumping machine 44 in frame plate 43, detection mechanism 47 is arranged in frame plate 43.

[0059] After the monitoring unit 4 moves to the position to be detected, the hydraulic device 41 controls the telescopic end 42 to move and drive the frame plate 43 to precisely fit with the pipeline 6, then the liquid pumping machine 44 pumps out the water in the frame body to avoid the error caused by water to the detection, which is convenient for the subsequent detection mechanism 47 to measure the temperature of the surface of pipeline 6.

[0060] As shown in the figure, Figure 10 The detection mechanism 47 includes servo motor two 471, the output end of servo motor two 471 is fixedly connected with reciprocating screw rod 472, the outer surface of reciprocating screw rod 472 is threadedly connected with moving block 473, the outer surface of moving block 473 is provided with visual sensor 474, the inner wall of moving block 473 is also provided with polishing mechanism 475 and temperature measuring mechanism 476;

[0061] If the visual sensor 474 detects the attachment layer of barnacles on the detection site, the servo motor two 471 will drive the reciprocating screw rod 472 to rotate, so as to drive the polishing mechanism 475 to move above the attachment layer.

[0062] The outer surface of hydraulic device 41 is fixedly connected with one end of supporting rod one 36, the outer surface of servo motor two 471 is fixedly connected with the inner wall of frame plate 43.

[0063] As shown in the figure, Figure 11 The polishing mechanism 475 includes telescopic rod one 4751, the output end of telescopic rod one 4751 is fixedly connected with supporting plate two 4752, the bottom of supporting plate two 4752 is fixedly connected with drooping plate 4753, the bottom of drooping plate 4753 is rotatably connected with arc plate 4754, the bottom of arc plate 4754 is provided with polishing film 4755, the top of supporting plate two 4752 is symmetrically provided with top plate 4756, the outer surface of top plate 4756 is fixedly connected with micro electric cylinder 4757.

[0064] The telescopic rod one 4751 drives the support plate two 4752 to move downward, and makes the polishing film 4755 adhere to the attached layer. Then the servo motor controls the reciprocating screw rod 472 to rotate again, and drives the moving block 473 to reciprocate, and the two micro electric cylinders 4757 control the arc plate 4754 to change the angle along the drooping plate 4753, so that the polishing film 4755 is precisely adhered to the outer surface of the pipeline 6 and polished, and the attached layer adhered by the barnacles is removed, so as to avoid the attachment from hindering the direct contact between the temperature measuring mechanism 476 and the pipeline 6.

[0065] The outer surface of the telescopic rod one 4751 is fixedly connected with the inner wall of the moving block 473, and the output end of the micro electric cylinder 4757 is fixedly connected with the top of the arc plate 4754.

The detection port 4763 detects the temperature of the outer wall of the pipeline 6 and transmits it to the host end through the communication assembly 4764. When the temperature is too high, the host end will issue an alarm. However, if there is a small hole on the surface of the pipeline 6, the temperature at the hole cannot be detected. The liquid storage assembly 4766 inputs the transmission medium into the liquid filling groove 4765 through the transmission pipe 4767, so as to form a temperature transmission medium between the detection port 4763 and the hole, thereby facilitating the temperature transmission from the hole to the detection port 4763.

[0068] The outer surface of the telescopic rod two 4761 is fixedly connected with the inner wall of the moving block 473, and the end of the transmission pipe 4767 away from the liquid storage assembly 4766 is connected with the liquid filling groove 4765.
