TECHNICAL FIELD

[0001] The present application relates to the technical field of heat monitoring, and relates to a power supply line visual monitoring instrument. BACKGROUND

[0002] Temperature measurement is required for cable heads in high-temperature seasons. Summer is the season when electrical equipment is most vulnerable and accidents are most likely to occur, especially high temperature seriously affects the safe operation of electrical equipment, especially the temperature of electrical contacts and high-voltage cable heads. Temperature measurement of these weak links is the focus of work in the electrical workshop.

[0003] In the monitoring process of the power supply line, a thermal imager is usually used for monitoring, that is, the cable head is monitored by thermal imaging to observe whether the temperature is too high. However, there are problems in actual monitoring. Workers usually hold the thermal imager to monitor, which is laborious. For transformers and other devices arranged at a high position, the cable head to be monitored is located close to the device, and is also located at a high position. This makes monitoring difficult, the point irradiated by the thermal imager is far away, and the monitoring accuracy is affected. At the same time, the imaging position of the thermal imager is difficult to reverse, and workers need to move to the other side to take pictures. However, due to problems such as device arrangement, it is difficult to reach the position on one side, which greatly limits the monitoring. SUMMARY

[0041] A second driving motor 25 is arranged on the outer surface of the concave frame 17, the output shaft of the second driving motor 25 and the end of the rotating shaft 18 are jointly sleeved with a synchronous belt 26, the synchronous belt 26 is driven to rotate by the second driving motor 25, and the rotating shaft 18 is further rotated.

[0042] As shown in the drawings, Figure 1 The thermal imaging module includes a thermal imager 34, which is an infrared thermal imager 34, including an optical-mechanical assembly, a focusing / zooming assembly, an internal non-uniformity correction assembly, an imaging circuit assembly, and an infrared detector / refrigerator assembly, which are prior art and will not be described in detail, the rear end of the connecting handle 27 is installed with a connecting block 32 in the front-rear direction through a displacement mechanism, a groove 33 is formed in the rear end of the connecting block 32, the groove 33 is rotatably connected with the lower end of the thermal imager 34, a second brake motor 35 is fixedly connected to one side of the connecting block 32, the output shaft of the second brake motor 35 is fixedly connected to one side of the lower end of the thermal imager 34, a first brake motor 28 is fixedly installed on one side of the base 1, and the output shaft of the first brake motor 28 is fixedly connected to the side of the connecting handle 27.

The arrangement of this part provides multiple degrees of freedom for adjusting the thermal imager 34, so that the shooting is more flexible.

[0044] As shown in Figure 9 , the remote control module 36 comprises a battery, a wireless transmission module and a main control unit installed at the connecting handle 27. The wireless transmission module is used to realize the interaction between the mobile terminal and the main control unit, and is also used to receive the shooting data of the thermal imager 34. The battery is used to supply power to the main control unit. The main control unit is electrically connected to the thermal imager 34 to complete the transmission of data.

During subsequent monitoring, the first drive motor 12 is controlled to rotate the rotating wheel 8, so that the base 1 climbs along the surface of the cable to conveniently reach the position of the cable head, and the thermal imager 34 is used for shooting. The data transmission is realized through the remote control module 36, and the data is transmitted to the mobile terminal of the worker for observation, so that the monitoring of the high position can be conveniently realized.

[0046] As shown in Figure 11 , Figure 12As shown, in the process of the base 1 climbing, since the inner plate 19 is against the surface of the cable, the problem of climbing obstruction does not occur, when it is necessary to change the shooting position of the thermal imager 34, the second driving motor 25 is controlled to rotate the rotating shaft 18, and then the rubber sleeve 21 contacts the surface of the cable, since the rubber sleeve 21 generates a large friction force when being squeezed, and at the same time, the friction force of the transverse roller when rotating relative to the surface of the cable is small, therefore, the rotation of the base 1 is not hindered, so as to achieve the purpose of changing direction, change the shooting direction of the thermal imager 34, and monitor the cable head at each angle.
