[0035] In the process of device transportation, jolting vibration is inevitable. When the vibration occurs, it is first transmitted to the buffer plate 15. The buffer plate 15 is directly in contact with the external vibration source, and its function is to disperse the impact force of vibration and transmit it to the rotating bar one 10 and the rotating bar two 14 connected thereto. The buffer plate 15 is made of a material with certain elasticity and toughness, so that when it bears the impact of vibration, it can produce a certain deformation itself, thereby preliminarily relieving the energy of vibration. Then, the buffer plate 15 pushes the rotating bar one 10 to rotate. The rotating bar one 10 converts the transverse impact force of the buffer plate 15 into the longitudinal sliding power of the sliding block one 8. The rotation of the rotating bar one 10 makes the sliding block one 8 slide along the connecting rod one 7. The connecting rod one 7 provides a stable sliding track for the sliding block one 8, ensuring that the sliding block one 8 can do linear reciprocating motion when it is under stress. The sliding block one 8 extrudes the first spring 9 in the sliding process. The first spring 9 deforms elastically, converting the kinetic energy generated by vibration into its own elastic potential energy and storing it. At the same time, the vibration of the buffer plate 15 also drives the rotating bar two 14 to transmit the impact force of the buffer plate 15 to the sliding block two 12. The movement of the rotating bar two 14 extrudes the second spring 13. The sliding block two 12 slides along the connecting rod two 11 under the action of the rotating bar two 14, thereby extruding the second spring 13. The connecting rod two 11 provides a sliding track for the sliding block two 12, ensuring the stability of its movement. The second spring 13 works with the first spring 9 to further convert the vibration energy into elastic potential energy when extruded. Through the elastic deformation of the first spring 9 and the second spring 13, and the buffering effect of the buffer plate 15, the vibration generated in the process of transportation is gradually offset. This buffering mechanism effectively reduces the direct impact of vibration on the insulation resistance meter 5. It greatly reduces the influence of vibration on the insulation resistance meter 5, reduces the damage to the insulation resistance meter 5 caused by vibration and jolting, and ensures that it can maintain good performance state in the process of transportation.
[0036] Referring to Figure 5The winding assembly comprises a first connecting plate 17, which serves as a base support component of the winding assembly and provides a mounting and fixing plane for the winding drum 21, the spring piece 20, the rotating shaft 18, the fixing column 19 and other components. The winding drum 21 is rotatably connected inside the first connecting plate 17. The winding drum 21 is a component for winding the connecting wire 24, and its surface is tightly attached to the connecting wire 24. The side wall of the connecting wire 24 is attached to the inside of the winding drum 21. The spring piece 20 is arranged on the upper surface of the first connecting plate 17. The spring piece 20 is the power source of the winding assembly. The protective shell 16 is fixedly connected to the upper surface of the first connecting plate 17. The protective shell 16 can protect the spring piece 20 from external impacts, dust and other influences. The rotating shaft 18 is rotatably connected inside the first connecting plate 17. The rotating shaft 18 provides a rotating central axis for the winding drum 21. The fixing column 19 is fixedly connected to the upper surface of the first connecting plate 17. The fixing column 19 is used to fix one end of the spring piece 20. One end of the spring piece 20 is fixedly connected to the inside of the rotating shaft 18, and the other end is fixedly connected to the side wall of the fixing column 19. This connection mode ensures that the spring piece 20 can effectively transmit the torsional force to the rotating shaft 18 when it is twisted and released, thereby driving the winding drum 21 to rotate. The winding drum 21 is fixedly connected to the side wall of the rotating shaft 18 inside, which ensures that the winding drum 21 and the rotating shaft 18 rotate synchronously. The support plate 23 is fixedly connected to the lower surface of the first connecting plate 17. The support plate 23 serves to support and reinforce the first connecting plate 17. The second connecting plate 22 is fixedly connected to the lower surface of the support plate 23. The second connecting plate 22 further enhances the stability of the winding assembly. The fixed block 27 is fixedly connected to the upper surface of the second connecting plate 22. The connecting wire 24 is fixedly connected to the inside of the fixed block 27 away from the detection head 25. The fixed block 27 is used to firmly fix the end of the connecting wire 24 away from the detection head 25, ensuring that this end of the connecting wire 24 does not loosen during winding and unwinding, and ensuring the normal operation of the winding assembly.
[0037] When the device is used for detection, first, the buckle 3 is released, after the buckle 3 is released, the cover plate 2 can be easily opened. Then, the access head 26 is inserted into the insulation resistance meter 5. Subsequently, by pulling the connecting line 24 of the detection head 25 part, when the connecting line 24 is pulled, because it is closely attached to the winding drum 21, it will drive the winding drum 21 to start rotating. The winding drum 21 is a key component for winding the connecting line 24, when the connecting line 24 is pulled by external force, the winding drum 21 rotates by virtue of the friction with the connecting line 24. The winding drum 21 is fixedly connected inside the rotating shaft 18 side wall, so the rotation of the winding drum 21 further drives the rotating shaft 18 to rotate. The rotating shaft 18 provides a rotating center axis for the winding drum 21, so that the winding drum 21 can stably rotate around it, and it is also a connecting component of the clock spring 20, which transmits the torsion of the clock spring 20 to the winding drum 21. The rotation of the rotating shaft 18 will tighten the clock spring 20. The clock spring 20 is the power source of the winding assembly, which stores energy through its elastic deformation. When twisted by the rotating shaft 18, the clock spring 20 continuously stores elastic potential energy, reserving power for subsequent automatic winding operation. At this time, the detection head 25 can be used to detect the electromechanical device. The detection head 25 is used to directly contact the measured electromechanical device, can apply the voltage signal output by the insulation resistance meter 5 to the device, and collect the feedback current signal of the device. The detected data is transmitted back to the insulation resistance meter 5 through the connecting line 24. The insulation resistance meter 5 measures the leakage current flowing through the insulation part of the device by applying a direct current voltage to the measured electromechanical device, so as to calculate the insulation resistance value of the device. The precise circuit and calculation chip built-in the insulation resistance meter 5 process and analyze the collected data, and display the accurate data on its display screen for the staff to analyze. When the detection is completed, the pulling force on the detection head 25 is reduced, at this time, the clock spring 20 will slowly rebound because of the elastic potential energy stored before, one end of the clock spring 20 is fixedly connected inside the rotating shaft 18, the other end is fixedly connected to the side wall of the fixed column 19, the fixed column 19 is used to fix one end of the clock spring 20, so that the clock spring 20 can maintain a stable working state during the process of storing and releasing energy. The rebound force generated when the clock spring 20 rebounds will drive the rotating shaft 18 to rotate in the opposite direction, the rotating shaft 18 in turn drives the winding drum 21 to rotate, the winding drum 21 starts to slowly wind the connecting line 24. This winding method avoids that the connecting line 24 is tangled together in disorder, which is convenient for carrying and using, and the orderly winding reduces the damage of the connecting line 24 caused by excessive bending and twisting, and prolongs the service life of the connecting line 24.
[0038] Working principle: when using the device for detection, by unfastening the buckle 3 to open the cover plate 2, then by inserting the access head 26 into the inside of the insulation resistance meter 5, then by pulling the connecting line 24 of the detection head 25 part, so as to drive the winding drum 21 to start rotating, and then drive the rotating shaft 18 to rotate, so as to tighten the spring piece 20, at this time, the electromechanical equipment can be detected by the detection head 25, and the accurate data can be displayed on the display screen of the insulation resistance meter 5 for the staff to analyze, when the detection is completed, at this time, the tension of the detection head 25 is reduced, the spring piece 20 slowly rebounds, the rebound force generated by the spring piece 20 drives the rotating shaft 18 to rotate in the opposite direction, so as to drive the winding drum 21 to rotate, slowly winding the connecting line 24, avoiding the connecting line 24 winding together in disorder, convenient to carry and use, also prolong the service life of the test line, in the process of equipment transportation, the vibration generated will be transmitted to the buffer plate 15, and the rotating bar 10 is pushed to rotate, the sliding block 8 is slid and the first spring 9 is extruded, at the same time, the rotating bar 14 also extrudes the second spring 13, and then the vibration generated is offset by the spring and the buffer plate 15, so as to achieve the protection effect of the insulation resistance meter 5, reduce the damage to the insulation resistance meter 5 caused by vibration.
