[0040] In the application, the starting operation motor 3007 is started to drive the rotating rod 3009 to rotate the rotating cylinder 3010, the traction loop groove 3011 on the rotating cylinder 3010 rotates to drive the traction rod 3016, the adjusting block 3015 drives the reciprocating sector gear 3014 to deflect on the shaft rod 3013, the reciprocating sector gear 3014 drives the traction rack 3020 to move on the U-shaped sliding groove block 3017, the traction rack 3020 drives the sliding block 3021 to move on the guide rod 3019 of the traction port 3018, the sliding block 3021 drives the extension block 3003 on the mounting block 3002 to move, the extension block 3003 drives the assembly block 3005 on the operation block 3004 to move, so that the two push blocks 3006 reciprocate, the two push blocks 3006 push the connecting line 32, so that the connecting line 32 vibrates, which helps to shake off the rain or snow attached to the connecting line 32, reduces the weight of the connecting line 32, and improves the protection of the connecting line 32.

[0041] With reference to Figures 1-3 The back of the monitoring information collector 13 is fixedly provided with an n-shaped protective box 23, the operation motor 3007 and the mounting wire 3008 are located in the inside of the n-shaped protective box 23, the monitoring information collector 13 is fixedly provided with an antenna 20, the monitoring information collector 13 is fixedly provided with an electric lead wire 21, and the electric lead wire 21 is fixedly provided with a plug 22.

[0042] In the application, the plug 22 is plugged with the socket, the multiple sensors 33 can transmit the conditions of the oil-immersed transformer 10 to the monitoring information collector 13 through the connecting line 32 for collection, and then transmit to the background through the antenna 20.

[0043] Working principle: The plug 22 is connected to the socket. Multiple sensors 33 transmit information about the oil-immersed transformer 10 via the connecting cable 32 to the monitoring information collector 13 for collection. The information is then transmitted to the backend via the antenna 20. In rainy or snowy weather, the operating motor 3007 is activated, causing the rotating rod 3009 to drive the rotating cylinder 3010 to rotate. The traction return groove 3011 on the rotating cylinder 3010 rotates, pulling the traction rod 3016. This causes the adjusting block 3015 to drive the reciprocating sector gear 3014 to deflect on the shaft 3013. The reciprocating sector gear 3014 then drives the traction gear... The traction rack 3020 moves on the U-shaped slide block 3017. The traction rack 3020 drives the sliding block 3021 to move on the guide rod 3019 on the traction port 3018. The sliding block 3021 drives the extension block 3003 on the mounting block 3002 to move. The extension block 3003 drives the assembly block 3005 on the operating block 3004 to move, so that the two push blocks 3006 reciprocate. The two push blocks 3006 push the connecting line 32, causing the connecting line 32 to vibrate. This helps to shake off the rainwater or snow attached to the connecting line 32, reduce the load on the connecting line 32, and improve the protection of the connecting line 32.

[0044] Example 2

[0045] like Figures 7-8 As shown, this is a schematic diagram of a multi-dimensional monitoring device for the protection status of an oil-immersed transformer according to another preferred embodiment of the present invention. During use, the connecting line 32 is subject to thermal expansion and contraction, as well as its own weight, causing it to easily exhibit a "U" shape of varying amplitude. This results in the push block 3006 sliding on the connecting line 32 during reciprocating movement, leading to poor swaying of the connecting line 32 and affecting its performance. Therefore, based on Embodiment 1, the device is further improved by equipping the support block 3000 with a positioning mechanism 40. The positioning mechanism 40 includes a guide block 4000, and the guide block 4000 is fixedly equipped with the support block. At the bottom of 3000, and with the guide block 4000 located on one side of the two push blocks 3006, the bottom of the guide block 4000 is fixedly equipped with a first positioning block 4001, and the bottom of the vertical block 3001 is fixedly equipped with a second positioning block 4002. Both the first positioning block 4001 and the second positioning block 4002 are provided with multiple positioning holes 4003. The positioning holes 4003 on the first positioning block 4001 and the positioning holes 4003 on the second positioning block 4002 are correspondingly overlapped, and the positioning holes 4003 on the first positioning block 4001 and the positioning holes 4003 on the second positioning block 4002 are movably assembled with the connecting line 32.

[0046] Working principle: the connecting line 32 is loaded on the positioning hole 4003 on the first positioning block 4001 and the positioning hole 4003 on the second positioning block 4002, so that the connecting line 32 between the positioning hole 4003 on the first positioning block 4001 and the positioning hole 4003 on the second positioning block 4002 plays a supporting role, reduces the traction section of the connecting line 32 in use to reduce the influence of thermal expansion and cold shrinkage and self weight, and improves the operation effect.

[0047] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
