[0002] The transformer oil tank is filled with oil, but the oil in the transformer oil pillow cannot be too full; the oil tank and the oil pillow are connected by a pipe. When there is a lack of oil in the oil tank, the oil in the oil pillow will flow down the pipe and replenish the oil tank to keep it full of oil; at the same time, when the transformer load increases, the oil temperature rises, the transformer oil expands, and the oil tank can no longer hold it, it will also flow up the pipe and flow back into the oil pillow.

The utility model solves the problem of poor intelligence of the existing device. When the oil level drops, the top temperature sensor floats out of the oil surface, and the temperature inside and outside the oil is different, so that the monitoring value drops. In turn, the values ​​monitored by the middle temperature sensor and the bottom temperature sensor also drop, and the data is transmitted to the display screen to understand the oil level status; secondly, the floating plate floats on the oil surface, and the laser sensor is started to monitor the distance between the floating plate and the internal top, and then the data is transmitted to the display screen, thereby improving the accuracy of internal oil level monitoring and improving the practicality of the existing monitoring device.

[0023] The shock absorbing mechanism 7 includes a top plate 701 and a second bottom plate 702, fixed blocks 703 are provided on both sides of the top of the second bottom plate 702, one side of the fixed block 703 is movably connected with a movable rod 704, one side of the movable rod 704 is provided with a transmission box 705, a receiving column 706 is fixedly installed on the top surface of the fixed block 703, a movable column 707 is movably connected to the surface of the receiving column 706, a spring 708 is provided on the surface of the receiving column 706, and the top of the movable column 707 is connected to the bottom end of the second bottom plate 702.

[0024] A spring 708 is provided on the surface of the accommodating column 706. After the protective plate 6 first receives the impact force, the top plate 701 is squeezed toward the second bottom plate 702 as the force presses. At the same time, the movable column 707 moves in the accommodating column 706. At the same time, the spring 708 is squeezed by the force, so that the spring 708 effectively relieves part of the impact force.

[0025] Reference Figure 1-4 A slide groove 709 is provided inside the transmission box 705 , and an elastic metal plate 770 is provided inside the slide groove 709 . Slide blocks 711 are provided at both ends of the elastic metal plate 770 , and the slide block 711 is located on one side of the movable rod 704 .

[0026] Reference Figure 1-4 The telescopic mechanism 2 includes a motor 201, an output end of the motor 201 is provided with a driving gear 202, the driving gear 202 is meshed with a driven gear 203, the driven gear 203 is clamped with a threaded tube 204, a threaded column 205 is sleeved in the threaded tube 204, and the top of the threaded column 205 is connected to the bottom end of the first base plate 3.

[0027] By starting the motor 201, the output end of the motor 201 drives the driving gear 202 to rotate. Since the driving gear 202 is meshed with the driven gear 203, the driving gear 202 drives the driven gear 203 to rotate, and the driven gear 203 drives the threaded barrel 204 to rotate. The threaded barrel 204 is threadedly connected with the threaded column 205, so that the threaded column 205 rises, plays a lifting role, and is convenient for detection.

[0028] Reference Figure 1-4 A guide rod 8 is provided at the top of the base 1 , and a collar 9 is provided on the outer wall of the top of the guide rod 8 , and one end of the collar 9 is fixedly connected to the back side of the detection device 4 .

[0030] Working principle: when the device receives an external collision, the protective plate 6 first receives the impact force, and as the force squeezes the top plate 701, it squeezes toward the second bottom plate 702. At the same time, the movable column 707 moves in the accommodating column 706, and the spring 708 is squeezed by the force, so that the spring 708 effectively relieves part of the impact force. At the same time, the top plate 701 moves downward, thereby driving the slider 711 to squeeze the elastic metal plate 720 at one end of the extrusion movable rod 704, further decomposing the impact force of the protective plate 6; when the device needs to adjust the height, by starting the motor 201, the output end of the motor 201 drives the driving gear 202 to rotate. Since the driving gear 202 is meshed with the driven gear 203, the driving gear 202 drives the driven gear 203 to rotate, and the driven gear 203 drives the threaded cylinder 204 to rotate. The threaded cylinder 204 is threadedly connected with the threaded column 205, so that the threaded column 205 rises. At the same time, the ring 9 moves on the guide rod 8 to increase the stability of the device.
