[0018] Beneficial effects: The integrated control structure with the dial as the core can complete multiple transmission actions through single pressing + rotating operation: after pressing the dial to realize height switching, the lower supporting plate is driven to descend to release clamping, the rack drives the upper stop block to shrink synchronously, and the lower supporting plate is driven to ascend to assist in disengagement during the rotating process;

[0019] Compared with the dispersion operation of simultaneously controlling multiple pressure rods in the prior art, the design integrates the disassembly process into a single continuous operation, greatly simplifies the operation steps, reduces the operation difficulty of the maintenance personnel, and significantly shortens the disassembly time of the fault detection device.

[0020] The device effectively avoids accidental disengagement caused by non-human operation or accidental touch through multi-stage structure design. Under normal conditions, the height difference between the circular dialing groove two and the bottom of the inclined dialing groove two forms a physical barrier to the dialing column two. Even if the device is shaken, the dialing column two cannot enter the circular dialing groove two to trigger subsequent transmission, preventing structural loosening caused by shaking. During the initial rotation of the dial, the dialing column two slides along the circular dialing groove one in the "invalid operation interval", preventing the dial from rotating and causing the device to loosen due to slight accidental touch. The engagement structure of the limiting block and the upper stop block forms a forced operation sequence. The limiting block must be disengaged from the upper stop block by lowering the lower supporting plate before the upper stop block can be controlled to shrink, thereby eliminating the problem of the upper stop block shrinking prematurely due to accidental operation from a mechanical perspective. Multiple designs collectively ensure the secure installation of the detection device body in a non-maintenance state, completely solving the safety hazard of the fault detection device falling due to accidental touch in the prior art, and significantly improving the use safety and stability of the installation structure.

[0021] The "pressing-rotating" step operation during disassembly forms a clear logic chain: the lower supporting plate descends to release clamping, the upper stop block shrinks to release the top block, and the lower supporting plate ascends to assist in disengagement. Each step naturally connects through the rotation stroke of the dial, without the need for additional tools or complex judgment. At the same time, the structural design ensures precise linkage of each component action, avoiding the risk of operation jamming or failure, which not only facilitates maintenance personnel to quickly complete disassembly and assembly work, but also ensures operation reliability through the determinacy of the mechanical structure.

[0038] The mounting plate 1 is fixed to the inner wall of the transformer through the threaded columns 15; in this setting, the gear 7 is driven to rotate by external force, which can drive the rotating rod 6 to rotate around the rotating shaft, when the rotating rod 6 rotates, the inclined pushing groove 8 on the surface of the rotating rod 6 will produce relative sliding with the pushing column 9, the connecting head 10 is pushed to move through the guiding effect of the inclined pushing groove 8, and then the two upper stop blocks 11 are controlled to synchronously shrink into or stretch out of the hollow tube 2; when the detection device body 4 needs to be disassembled, after the upper stop blocks 11 are controlled to shrink into the hollow tube 2, the mounting plate 2 can freely slide along the outer side wall of the hollow tube 2, which is convenient to separate from the outside of the hollow tube 2, and the detection device body 4 is quickly disassembled; when the detection device body 4 is installed to the outside of the plurality of hollow tubes 2 through the mounting plate 2, the upper stop blocks 11 are controlled to stretch out from the outside of the hollow tube 2, at this time, the plurality of damping springs 13 produce upward pushing force due to elastic potential energy, the lower supporting plate 14 is pushed to press the mounting plate 2 upward, so that the mounting plate 2 is closely attached to the lower surface of the upper stop block 11, thereby realizing firm installation of the mounting plate 2; at the same time, the mounting plate 2 can slightly slide along the outer side wall of the hollow tube 2, and cooperates with the elastic buffering effect of the damping springs 13, which can effectively absorb external vibration and play a damping buffering effect.

[0039] As shown in Figure 2 and Figure 5 , the two sides of the lower supporting plate 14 are symmetrically fixedly connected with rotating heads 25, one supporting plate 26 is commonly rotationally connected between the front and rear two rotating heads 25 through a rotating shaft, the bottom of the supporting plate 26 is rotationally connected with a concave moving part 27 through a rotating shaft, the upper surface of the concave moving part 27 is fixedly connected with an L-shaped connecting frame 28, the inner side of the L-shaped connecting frame 28 is fixedly connected with a pushing column 29 inside the circular pushing groove 21.

[0041] When the device is subjected to external vibration, the lower supporting plate 14 will produce downward displacement with vibration, the rotating head 25 drives the supporting plate 26 to rotate around the rotating shaft, the supporting plate 26 pushes the concave moving piece 27 to slide along the outer side wall of the guide rod 41 in a small amplitude during the rotating process, the sliding cooperation of the concave moving piece 27 and the guide rod 41 and the rotating buffering of the supporting plate 26 are utilized to further enhance the damping buffering effect of the device, and the influence of vibration on the detection device body 4 is reduced.

[0042] As shown in Figure 2 , Figure 6 , Figure 7 and Figure 8 , the inside of the mounting plate one 1 is embedded with the mounting box 16, the inside of the mounting box 16 is slidably connected with the lifting plate 17, a plurality of extrusion springs 18 are fixedly connected between the lifting plate 17 and the mounting box 16, the upper surface of the lifting plate 17 is symmetrically rotatably connected with the round rod 19 through the rotating shaft, the top end of the round rod 19 penetrates to the upper side of the mounting plate one 1, and is fixedly connected with the dial plate 20, the upper surface of the dial plate 20 is provided with the circular dialing groove one 21, one end of the inside of the circular dialing groove one 21 is integrally formed with the inclined dialing groove two 22, one end of the inclined dialing groove two 22 away from the circular dialing groove one 21 is integrally formed with the circular dialing groove two 23, and one end of the circular dialing groove two 23 away from the inclined dialing groove two 22 is integrally formed with the inclined dialing groove three 24;

[0043] The lower surface of the dial plate 20 is provided with the circular dialing groove three 30, one end of the inside of the circular dialing groove three 30 is integrally formed with the inclined dialing groove four 31, and one end of the inclined dialing groove four 31 away from the circular dialing groove three 30 is integrally formed with the circular dialing groove four 32;

[0044] The inside lower surface of the circular dialing groove two 23 and the inside lower surface of the inclined dialing groove three 24 are on the same horizontal plane, and are higher than the inside lower surface of the inclined dialing groove two 22 and the inside lower surface of the circular dialing groove one 21, and the inside lower surface of the inclined dialing groove two 22 and the inside lower surface of the circular dialing groove one 21 are on the same horizontal plane;

[0045] The upper surface of the mounting plate one 1 is fixedly connected with a hydraulic box one 33, the upper surface of the mounting plate one 1 is fixedly connected with a hydraulic box two 34 in front of and behind the hydraulic box one 33, a through pipe 35 is fixedly and communicatively connected between the hydraulic box one 33 and the hydraulic box two 34, a piston block one 36 is slidably connected in the hydraulic box one 33, a connecting head two 37 is fixedly connected to one end of the piston block one 36 close to the dial plate 20, one end of the connecting head two 37 away from the piston block one 36 penetrates to the outside of the hydraulic box one 33 and is fixedly connected with a dialing column three 38, the top end of the dialing column three 38 extends to the inside of the circular dialing groove three 30 and is slidably connected with the circular dialing groove three 30, a piston block two 39 is slidably connected in the hydraulic box two 34, a rack 40 is fixedly connected to one side of the piston block two 39 close to the hollow tube 2, one end of the rack 40 away from the piston block two 39 penetrates to the outside of the hydraulic box two 34 and is slidably connected with the hydraulic box two 34, the outer side wall of the rack 40 is slidably connected with the outer side wall of the gear 7;

[0046] The circular dialing groove one 21, the circular dialing groove two 23, the circular dialing groove three 30 and the circular dialing groove four 32 are all small-section circular ring-shaped groove bodies; wherein the diameter of the circular dialing groove one 21 is greater than the diameter of the circular dialing groove two 23, the diameter of the circular dialing groove three 30 is smaller than the diameter of the circular dialing groove four 32; the inclined dialing groove two 22 gradually inclines to the center direction of the dial plate 20 in the extending process from the circular dialing groove one 21 to the circular dialing groove two 23; the inclined dialing groove three 24 gradually inclines to the outside direction of the dial plate 20 in the extending process from the circular dialing groove two 23 to the outside; the inclined dialing groove four 31 gradually inclines to the outside direction of the dial plate 20 in the extending process from the circular dialing groove three 30 to the circular dialing groove four 32;

[0047] Under normal state, the extrusion spring 18 is in slight compression state, pushes up the lifting plate 17 upward, so that the dial plate 20 keeps the upward position, at this time, the bottom end of the dialing column two 29 is attached to the inner lower surface of the circular dialing groove one 21; when the device is vibrated, the lower supporting plate 14 is lowered and drives the dialing column two 29 to move through the transmission structure, at this time, the dialing column two 29 will slide into the inclined dialing groove two 22 along the circular dialing groove one 21, because there is a bottom height difference between the circular dialing groove two 23 and the inclined dialing groove two 22, the circular dialing groove two 23 will block the dialing column two 29, so that it cannot continue to slide into the circular dialing groove two 23, thereby avoiding the vibration to trigger the subsequent structure transmission, and ensuring the stability of the device installation;

[0048] When it is necessary to disassemble the mounting plate 23 and the detection device body 4, first press down on the dial 20 to compress the spring 18 and drive the lifting plate 17 down until the bottom of the dial 29 is flush with the inner lower surface of the circular dial groove 23 and the inclined dial groove 24. At this time, the dial 29 has not disengaged from the circular dial groove 11 and the inclined dial groove 22. Then rotate the dial 20. Initially, the dial 29 will slide along the inner side of the circular dial groove 11. During this stage, the lower support plate 14 will not be pulled down. This section of the stroke is the rotation buffer zone of the dial 20, which can effectively avoid accidental rotation of the dial 20 and prevent the device from becoming loose.

[0049] As the actuating disc 20 continues to rotate, the second actuating column 29 will slide into the inner side of the inclined actuating groove 22. Under the guidance of the inclined actuating groove 22, the two actuating columns 29 move in opposite directions, pulling the concave moving part 27 through the L-shaped connecting frame 28, thereby driving the support plate 26 to rotate, causing the lower support plate 14 to descend and releasing the squeezing and clamping of the mounting plate 23 below.

[0050] During the sliding of the second actuating column 29 along the circular actuating groove 21 and the inclined actuating groove 22, the third actuating column 38 simultaneously slides along the inner side of the circular actuating groove 30. During this stage, the piston block 36 will not be moved. When the second actuating column 29 slides to the inner side of the circular actuating groove 23, the third actuating column 38 will enter the inner side of the inclined actuating groove 41. Under the pushing action of the inclined actuating groove 41, the second connector 37 drives the piston block 36 to slide inside the hydraulic box 33. Through the through pipe 35, pressure is applied to the inside of the hydraulic box 34, pushing the piston block 39 to move. This causes the rack 40 to move towards the gear 7. The rack 40 meshes with the gear 7, driving the rotating rod 6 to rotate, causing the upper stop block 11 to retract to the inner side of the hollow tube 2, releasing the upper stop block 11 from blocking the top of the mounting plate 2 3.

[0051] Continue rotating the dial 20. When the second dial 29 rotates to the inside of the inclined dial groove 34, the third dial 38 will slide inside the circular dial groove 42. At this time, the rack 40 remains stationary and the upper stop block 11 remains in a retracted state. At the same time, under the squeezing action of the inclined dial groove 34, the second dial 29 pushes the two concave moving parts 27 to move in opposite directions. Through the support plate 26, the lower support plate 14 is driven to rise. The lower support plate 14 pushes the mounting plate 23 upward, assisting the mounting plate 23 to detach from the inside of the hollow tube 2, thus completing the disassembly.

[0052] like Figure 9 As shown, the upper stop block 11 has a concave structure with an opening on the lower surface, and a limit block 43 is provided on the upper surface of the mounting plate 2 3 inside the upper stop block 11.

[0053] The upper stopper 11 is a concave structure with an open lower surface, and the upper surface of the second mounting plate 3 is fixedly provided with a limiting block 43 at the inner side of the upper stopper 11; when the second mounting plate 3 is subjected to the upward extrusion thrust of the lower supporting plate 14, the limiting block 43 will be clamped at the inner side of the upper stopper 11, and the mechanical limiting action is used to limit the shrinkage of the upper stopper 11 to the inner side of the hollow pipe 2; the structure design makes it necessary to control the lowering of the lower supporting plate 14 when the device is disassembled, so that the second mounting plate 3 is lowered under the action of its own gravity, and the limiting block 43 is separated from the inner side of the upper stopper 11, and then the upper stopper 11 is controlled to shrink, so as to ensure the sequence of the disassembly operation, and further improve the installation stability of the device.

[0054] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
