[0038] Through the arrangement of the above structure, the three sections of insulating rods 2 are unfolded in sequence, and after unfolding, the telescopic hook 221 at the hinge point is rotated to hook it on the locking buckle 22 of another adjacent section of insulating rod 2, thereby forming a stably unfolded long straight insulating rod 2 structure, and then the threaded rod 21 at the bottom end of the lower section insulating rod 2 is inserted into the threaded sleeve 101, and the insulating rod 2 is rotated to fix the threads between the two, which effectively improves the convenience of disassembly and installation and improves the efficiency of test wiring.

When the worm 63 is rotated in the reverse direction, the dynamic clamp 54 will automatically reset and open under the rebound action of the first spring 551;

[0040] By setting the above structure, the worm 63 is rotated to drive the worm wheel 62 to rotate, and then drive the winding shaft 6 to rotate, so that the pull rope 61 is wound around the winding shaft 6, thereby pulling the pull plate 521 in the clamping groove 52 to slide, so that the dynamic clamp 54 is close to the fixed clamp 51, and finally the dynamic clamp 54 and the fixed clamp 51 will be clamped and fixed on the conductive part of the high-altitude power equipment to be tested, so as to realize high-altitude wiring, avoid the safety and low efficiency problems of manual climbing wiring and other methods, effectively improve the wiring speed, ensure the safety of test wiring, and utilize the self-locking characteristics between the worm 63 and the worm wheel 62, so that the dynamic clamp 54 and the fixed clamp 51 will not shift during the test, improve the clamping stability, and ensure the test effect.

[0041] Reference Figure 4 , Figure 5 , wherein a locking box 7 is fixedly connected to the side wall of the upper insulating rod 2, a locking groove 71 is provided on the top of the locking box 7, a locking slider 72 is slidably connected in the locking groove 71, a second spring 73 is fixedly connected between the bottom end of the locking slider 72 and the locking groove 71, the top of the locking slider 72 is in contact with the side wall of the winding shaft 3, and the upper end of the test line 31 passes through the inner cavity of the winding shaft 3 and is fixed and electrically connected to the side wall of the dynamic clamp 54;

[0042] Through the setting of the above-mentioned structure, after stopping pulling the test line 31, the winding shaft 3 will be in a locked state under the extrusion force generated by the locking slider 72 and the second spring 73, so as to avoid the test line 31 shaking or even falling off the plug interface due to factors such as wind during the test, thereby ensuring the wiring effect and improving the safety of the test.

[0043] Reference Figure 3 , Figure 4 , wherein the heat dissipation part includes an air guide groove 8, which is provided on the side wall of the upper insulating rod 2, and a pneumatic blade 81 is rotatably connected in the air guide groove 8, a piston groove 82 is provided in the upper insulating rod 2, a first magnetic plate 83 is slidably connected in the piston groove 82, a third spring 84 is fixedly connected between the top of the first magnetic plate 83 and the piston groove 82, a second magnetic plate 811 is fixedly connected to the end of the pneumatic blade 81, two groups of the second magnetic plates 811 are symmetrically arranged, and the second magnetic plates 811 and the first magnetic plates 83 are magnetically repelled, the side walls of the piston groove 82 are respectively connected with an air inlet pipe 821 and an air outlet pipe 822, a plurality of heat dissipation holes 321 are provided on the side wall of the baffle plate 32, the heat dissipation holes 321 are connected with the inner cavity of the baffle plate 32, the other end of the air outlet pipe 822 is connected with the inner cavity of the baffle plate 32, and a one-way valve is provided in both the air inlet pipe 821 and the air outlet pipe 822;

[0044] By setting the above-mentioned structure, the wind force in the high altitude will drive the pneumatic blades 81 in the air guide groove 8 to rotate. At this time, the repulsive effect between the first magnetic plate 83 and the second magnetic plate 811 will cause the first magnetic plate 83 to slide into the piston groove 82 during the rotation of the pneumatic blade 81, thereby compressing the gas in the piston groove 82, and under this squeezing action, the one-way valve in the air outlet pipe 822 is opened. At this time, the airflow in the piston groove 82 will enter the inner cavity of the wire baffle plate 32 along the air outlet pipe 822, and blow along the heat dissipation hole 321 to the test line 31 wound on the winding shaft 3, thereby effectively dissipating the heat of the winding test line 31, avoiding overheating of the winding part of the test line 31 during the power-on test, improving the protection of the test line 31, and ensuring the durability of the test line 31.

[0045] Reference Figure 2 , Figure 6 , wherein the pneumatic part includes a pneumatic chamber 9, which is arranged in the mounting base 1, and the pneumatic chamber 9 is communicated with the inner cavity of the threaded sleeve 101, a pneumatic plate 91 is slidably connected in the pneumatic chamber 9, a trigger rod 911 is fixedly connected to the top of the pneumatic plate 91, and the trigger rod 911 extends through the threaded sleeve 101, a fourth spring 92 is fixedly connected between the bottom of the pneumatic plate 91 and the pneumatic chamber 9, a sealing ring 41 is fixedly connected in the adsorption groove 4, a double-headed piston rod 42 slides through the middle of the sealing ring 41, both ends of the double-headed piston rod 42 slide in contact with the inner wall of the adsorption groove 4, an inflation tube 93 is communicated with the side wall of the pneumatic chamber 9, an inflation cavity is formed between the sealing ring 41 and the top of the double-headed piston rod 42, and the other end of the inflation tube 93 is communicated with the inflation cavity;

[0046] Through the arrangement of the above-mentioned structure, when the threaded rod 21 is inserted into the threaded sleeve 101, the trigger rod 911 will be squeezed, causing the air pressure plate 91 to move downward, thereby compressing the gas in the air pressure chamber 9, and allowing this part of the gas to enter the inflation chamber of the adsorption groove 4 along the inflation tube 93, so that the air pressure inside the inflation chamber increases, thereby pushing the double-headed piston rod 42 to slide upward, thereby enlarging the cavity at the bottom of the adsorption groove 4, and then reducing the internal air pressure. At this time, a low-pressure adsorption effect will be generated at the bottom of the adsorption groove 4, so that it fits tightly with the ground, effectively improving the stability of the mounting base 1.

[0047] Reference Figure 1-Figure 8 In the present invention, when in use, first place the mounting base 1 below the high-altitude power equipment to be tested, then unfold the three sections of insulating rods 2 in sequence, and rotate the telescopic hook 221 at the hinge point after unfolding to hook it on the locking buckle 22 of another section of insulating rod 2 adjacent to it, thereby forming a stably unfolded long straight insulating rod 2 structure, then insert the threaded rod 21 at the bottom end of the lower insulating rod 2 into the threaded sleeve 101, and rotate the insulating rod 2 to fix the threads between the two, and at this time the wiring part just contacts the conductive part of the high-altitude power equipment to be tested, and in the process of inserting the threaded rod 21 into the threaded sleeve 101, the trigger rod 911 will be squeezed to make the air pressure plate 91 move downward, thereby compressing the gas in the air pressure chamber 9, and making this part of the gas enter the inflation chamber of the adsorption tank 4 along the inflation pipe 93, so that the air pressure inside the inflation chamber increases, thereby pushing the double-headed piston rod 42 to slide upward, so that the adsorption The cavity at the bottom of the groove 4 becomes larger, thereby reducing the internal air pressure. At this time, a low-pressure adsorption effect will be generated at the bottom of the adsorption groove 4, making it fit closely with the ground, effectively improving the stability of the installation base 1; then the worm 63 is rotated to drive the worm wheel 62 to rotate, and then the winding shaft 6 is driven to rotate, so that the pull rope 61 is wound around the winding shaft 6, thereby pulling the pull plate 521 in the clamping groove 52 to slide, so that the dynamic clamp 54 is close to the fixed clamp 51, and finally the dynamic clamp 54 and the fixed clamp 51 will be clamped and fixed on the conductive part of the high-altitude power equipment to be tested, realizing high-altitude wiring, avoiding the safety and low efficiency problems of manual climbing wiring and other methods, effectively improving the wiring speed, ensuring the safety of the test wiring, and utilizing the self-locking characteristics between the worm 63 and the worm wheel 62, the dynamic clamp 54 and the fixed clamp 51 will not shift during the test, thereby improving the clamping stability and ensuring the test effect;

[0048] When the test wire 31 is pulled, the winding shaft 3 will overcome the squeezing and locking effect of the locking slider 72 and the second spring 73 on it under the action of the pulling force. At this time, the winding shaft 3 will rotate, so that the test wire 31 is loosened and stretched. After the pulling of the test wire 31 is stopped, the winding shaft 3 will be in a locked state under the squeezing force generated by the locking slider 72 and the second spring 73, so as to avoid the test wire 31 shaking or even falling off the plug interface due to factors such as wind during the test, thereby ensuring the wiring effect and improving the safety of the test. Finally, the bottom end of the test wire 31 is electrically connected to the high-voltage test equipment to complete all the wiring steps. During the test, since the upper section of the erected insulating rod 2 is in a higher position, the wind force in the air will push the wind blade 81 in the wind guide groove 8 to rotate. At this time, the repulsion between the first magnetic plate 83 and the second magnetic plate 811 will be used to make the first magnetic plate 83 rotate during the rotation of the wind blade 81. The piston groove 82 slides into the piston groove 82 to compress the gas in the piston groove 82, and under the squeezing effect, the one-way valve in the air outlet pipe 822 is opened. At this time, the airflow in the piston groove 82 will enter the inner cavity of the wire baffle 32 along the air outlet pipe 822, and blow along the heat dissipation hole 321 to the test wire 31 wound on the winding shaft 3, so as to effectively dissipate the heat of the winding test wire 31, avoid overheating of the winding part of the test wire 31 during the power-on test, improve the protection of the test wire 31, and ensure the test wire 31. Then, when the first magnetic plate 83 and the second magnetic plate 811 are separated from the magnetic area, the first magnetic plate 83 will be reset under the rebound action of the third spring 84, thereby generating suction in the compressed piston groove 82, thereby opening the one-way valve in the air inlet pipe 821, so that fresh air from the outside can be replenished into the piston groove 82 along the air inlet pipe 821, and this reciprocating motion not only achieves the above-mentioned fixed-point heat dissipation effect, but also increases the gas flow rate around the winding shaft 3, further improving the heat dissipation effect. Example

[0050] Reference Figure 1-Figure 8 , a high voltage test wiring auxiliary method, the steps are as follows:

[0051] Step 1: unfold the insulating rod 2 and fix it to the mounting base 1;

[0052] First, place the mounting base 1 below the high-altitude power equipment to be tested, then unfold the three sections of insulating rods 2 in sequence, and after unfolding, rotate the telescopic hook 221 at the hinge point to hook it on the locking buckle 22 of another section of insulating rod 2 adjacent to it, so as to form a stable unfolded long straight insulating rod 2 structure, then insert the threaded rod 21 at the bottom end of the lower section of insulating rod 2 into the threaded sleeve 101, and rotate the insulating rod 2 to fix the two threads together, and at this time, the wiring part just contacts the conductive part of the high-altitude power equipment to be tested, and the threaded rod 21 During the insertion of the threaded sleeve 101, the trigger rod 911 will be squeezed, causing the air pressure plate 91 to move downward, thereby compressing the gas in the air pressure chamber 9, and allowing this part of the gas to enter the inflation chamber of the adsorption tank 4 along the inflation tube 93, so that the air pressure inside the inflation chamber increases, thereby pushing the double-headed piston rod 42 to slide upward, so that the cavity at the bottom of the adsorption tank 4 becomes larger, thereby reducing the internal air pressure. At this time, the bottom of the adsorption tank 4 will produce a low-pressure adsorption effect, so that it fits tightly with the ground, effectively improving the stability of the mounting base 1;

[0053] Step 2: Pull the test wire 31 to electrically connect it to the high voltage test equipment;

[0054] The worm 63 is rotated to drive the worm wheel 62 to rotate, and then the winding shaft 6 is driven to rotate, so that the pull rope 61 is wound around the winding shaft 6, thereby pulling the pull plate 521 in the clamping groove 52 to slide, so that the dynamic clamp 54 is close to the fixed clamp 51, and finally the dynamic clamp 54 and the fixed clamp 51 are clamped and fixed on the conductive part of the high-altitude power equipment to be tested, so as to realize high-altitude wiring, avoid the safety and low efficiency problems of manual climbing wiring and other methods, effectively improve the wiring speed, ensure the safety of the test wiring, and use the self-locking characteristics between the worm 63 and the worm wheel 62, so that the dynamic clamp 54 and the fixed clamp 51 will not shift during the test, improve the clamping stability, and ensure the test effect;

[0055] Step 3: Make a stable electrical connection between the wiring part and the conductive part of the device under test;

[0056] When the insulating rod 2 is unfolded, the test wire 31 is pulled. Under the action of the pulling force, the winding shaft 3 will overcome the squeezing and locking effect of the locking slider 72 and the second spring 73 on it. At this time, the winding shaft 3 will rotate, so that the test wire 31 is loosened and stretched. After the test wire 31 is stopped from being pulled, the winding shaft 3 will be in a locked state under the squeezing force generated by the locking slider 72 and the second spring 73, so as to avoid the test wire 31 shaking or even falling off the plug interface due to factors such as wind during the test, thereby ensuring the wiring effect and improving the safety of the test. Finally, the bottom end of the test wire 31 is electrically connected to the high-voltage test equipment, so as to complete all the wiring steps.

[0057] Step 4: perform a high voltage test and dissipate heat from the test wire 31 wound on the winding shaft 3;

[0058] During the test, since the upper section of the erected insulating rod 2 is at a higher position, the wind force in the air will push the pneumatic blades 81 in the air guide groove 8 to rotate. At this time, the repulsive effect between the first magnetic plate 83 and the second magnetic plate 811 will cause the first magnetic plate 83 to slide into the piston groove 82 during the rotation of the pneumatic blades 81, thereby compressing the gas in the piston groove 82. At this time, the airflow in the piston groove 82 will enter the inner cavity of the wire baffle plate 32 along the air outlet pipe 822, and blow along the heat dissipation hole 321 to the test line 31 wound on the winding shaft 3, thereby effectively dissipating the heat of the winding test line 31, avoiding overheating of the winding part of the test line 31 during the power-on test, improving the protection of the test line 31, and ensuring the durability of the test line 31.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
