[0002] At present, transformers are often damaged due to high temperatures during use. Therefore, it is necessary to install temperature measuring equipment on the transformer to monitor the temperature inside the transformer in real time to ensure the safe use of the transformer.

[0003] At present, with the continuous advancement of science and technology, traditional wired temperature measurement equipment has been gradually replaced by wireless temperature measurement equipment, which mainly uses temperature probes to detect the temperature inside the transformer, and transmits the temperature information to the thermometer in real time through the signal line. The wireless signal transmitter on the thermometer transmits the signal to the remote terminal in real time. Although the existing wireless temperature measurement equipment has a high degree of technology, it still has the following shortcomings in terms of practicality:

[0004] First, the temperature measuring device is connected to the temperature measuring probe through a long signal line. When the device is carried, it is not convenient to roll up the long signal line. This is not only inconvenient for people to carry, but also the temperature measuring probe is easily dragged to the ground and damaged.

[0005] Secondly, it is not easy to fix the temperature measuring equipment firmly on the transformer during use. After people leave, the temperature measuring equipment may easily fall and break accidentally. Utility Model Content

[0028] Rotating shaft 7: The bottom end of the rotating shaft 7 is connected to the top inner wall of the temperature measuring instrument 2 through a bearing;

[0029] The capstan 8 is fixedly mounted on the rotating shaft 7, and the signal line 4 is wound around the capstan 8;

[0030] Manual control assembly: It includes a transmission shaft 9, a worm 10, a handwheel 11 and a worm gear 12. The transmission shaft 9 is connected to the inner walls of both sides of the mounting frame 6 through two bearings. The worm 10 is fixedly sleeved on the transmission shaft 9 and located inside the mounting frame 6. The handwheel 11 is fixed to the outer wall of one end of the transmission shaft 9 and is located outside the mounting frame 6. The worm gear 12 is fixedly sleeved on the rotating shaft 7 and meshes with the worm 10.

[0031] In this embodiment, the worm 10 on the transmission shaft 9 is rotated by controlling the hand wheel 11, and then the worm wheel 12 meshing with the worm 10 controls the winding drum 8 on the rotating shaft 7 to rotate, so that the longer signal line 4 can be rolled up. This not only makes it convenient for people to carry, but also effectively prevents the temperature probe 5 from being dragged to the ground and causing damage, thereby improving practicality.

The thermometer 2 can be firmly fixed to the transformer 1 during use to prevent it from accidentally falling and breaking after people leave.

[0037] Secondly, the worm 10 on the transmission shaft 9 is controlled to rotate forwardly by the hand wheel 11, and then the worm wheel 12 meshing with the worm 10 controls the winding drum 8 on the rotating shaft 7 to rotate forwardly, and the temperature measuring probe 5 connected to one end of the signal line 4 is released into the transformer 1, and the temperature inside the transformer 1 is detected by the temperature measuring probe 5, and the temperature information is transmitted to the thermometer 2 in real time through the signal line 4, and the wireless signal transmitter 3 on the thermometer 2 transmits the signal to the remote terminal in real time, so as to achieve the effect of wireless transmission temperature measurement;

[0038] Finally, when not in use, the worm 10 on the transmission shaft 9 is controlled by the hand wheel 11 to rotate in the opposite direction, and then the worm wheel 12 engaged with the worm 10 will control the winding drum 8 on the rotating shaft 7 to rotate in the opposite direction, so that the longer signal line 4 can be rolled up. This not only makes it convenient for people to carry, but also effectively prevents the temperature probe 5 from being dragged to the ground and causing damage.
