[0073] The top spring 25 is arranged on a side of the guide slider 22 opposite to the integrated plate 26 .

[0074] It should be noted that the shape of the positioning hoop 21 is one-half of a hollow cylinder, and the two positioning hoops 21 can form a complete hollow cylinder, and the cylindrical surface composed of the two positioning hoops 21 is also provided with an annular groove matching the guide slider 22. The positioning hoop 21 of special shape can enable the insulator 1 to enter between the two positioning hoops 21 when separated, so that the two can form an effective connection, and the annular groove provided on the cylindrical surface composed of the two positioning hoops 21 provides a stable moving path for the sliding of the guide slider 22, so that when the positioning hoop 21 and the guide slider 22 slide, the surface of the insulator 1 can be inspected for insulation through the inspection rod 27; the guide slider 22 is fan-shaped, and the angle of the fan-shaped guide slider 22 is less than 180 degrees. The fan-shaped guide slider 22 can form a stable connection with any positioning hoop 21, and the guide slider 22 with an angle less than 180 degrees can stay completely on a certain positioning hoop 21. The surface of the connecting plate 23 can achieve the purpose of separating and closing the two positioning hoops 21; a rectangular groove is provided on the surface of the connecting plate 23, and the connecting plate 23 and the sliding bar 24 are parallel to each other.

[0075] Furthermore, when it is necessary to connect the positioning hoop 21 and the insulator 1, the positions of the multiple positioning hoop 21 are moved. At this time, the two positioning hoop 21 will be separated so that they can be opened to provide space for the connection between the positioning hoop 21 and the insulator 1. At this time, the direction in which the positioning hoop 21 produces an opening can be moved toward the insulator 1. When the insulator 1 is located between the two positioning hoop 21, the position of the positioning hoop 21 is moved again so that the positioning hoop 21 is sleeved on the insulator 1.

[0076] Embodiment 2:

[0077] A connection positioning structure, applied to the above-mentioned maintenance device;

[0078] The connection and positioning structure includes a connection mechanism 3 and a positioning mechanism 4;

[0079] Specifically, the connecting mechanism 3 includes:

[0080] A built-in slide bar 31, a plurality of positioning hoops 21 are divided into two groups, and the built-in slide bar 31 is fixedly connected to one side of one group of positioning hoops 21;

[0081] An external guide tube 35, the external guide tube 35 is fixedly connected to one side of another set of positioning hoops 21, and the internal sliding rod 31 is inserted and connected to one side of the external guide tube 35;

[0082] The moving component is arranged on one side of the external guide tube 35 , and is used to move the position of the external guide tube 35 .

[0083] Specifically, the mobile components include:

[0084] A handle 32, the handle 32 is fixedly connected to one side of the built-in slide bar 31;

[0085] A B handle 34, which is fixedly connected to one side of the external guide tube 35;

[0086] The fixed spring 33 is arranged on a side opposite to the A handle 32 and the B handle 34 , and the built-in sliding rod 31 is inserted and connected in the middle of the fixed spring 33 .

[0087] It should be noted that the connection between the internal slide rod 31 and the external guide tube 35 and the positioning hoop 21 is far away from the center of the cylinder where the positioning hoop 21 is located. The straight line where the internal slide rod 31 and the external guide tube 35 are located passes through the cylinder where the positioning hoop 21 is located and does not contact the hollow part of the cylinder where the positioning hoop 21 is located. When the positioning hoop 21 and the internal slide rod 31 move, the two positioning hoops 21 can be separated, which can ensure that the insulator 1 and the positioning hoop 21 are effectively connected; the external guide tube 35 is in the shape of a hollow cylinder, and the hollow external guide tube 35 can make the internal slide rod 31 pass through its interior and form a connection with the positioning hoop 21, so as to achieve the purpose of controlling the closing and opening of the positioning hoop 21 by the A handle 32 and the B handle 34, and at the same time will not affect the connection between the two ends of the positioning hoop 21 and the insulator 1, and can form a stable and effective connection between the positioning hoop 21 and the insulator 1 through the connecting mechanism 3.

[0088] Furthermore, when it is necessary to perform insulation inspection on the surface of the insulator 1, the A handle 32 and the B handle 34 can be held with one hand to connect the insulator 1 and the positioning hoop 21. At this time, the other hand pulls the integrated board 26, the connecting board 23 and the slide bar 24 to slide and stretch the top spring 25. At this time, the two positioning hoops 21 will be connected to the insulator 1 under the operation of the connecting mechanism 3, while the integrated board 26 in the stretched state and the inspection rod 27 on its surface are not connected to the surface of the insulator 1. Then the integrated board 26 can be released. When the top spring 25 contracts, the integrated board 26 will slide again with the connecting board 23 and the slide bar 24 and drive various inspection devices set on its surface. The repair rod 27 moves toward one side of the surface of the insulator 1, and under the influence of the uneven characteristics of the surface of the insulator 1, the depth of connection between each repair rod 27 and the insulator 1 will also change accordingly. In the process of the integrated board 26 moving toward the insulator 1, the repair rod 27 located on the same horizontal line of the protrusion of the insulator 1 will preferentially come into contact with the insulator 1, and the repair rod 27 on the same horizontal line of the depression of the insulator 1 will be connected to the insulator 1 after the integrated board 26 moves further, and the repair rod 27 that has been connected to the protrusion of the insulator 1 will stretch the tension spring 28 arranged between the two during the further movement of the integrated board 26. At this time, the repair rod 27 can be connected to the integrated board 26 and the top During the stretching process of the positioning spring 25 and the tension spring 28, a closer connection is formed with the insulator 1. When the integrated board 26 is stationary, all the inspection rods 27 arranged on its surface will form effective contact with the insulator 1 and present a staggered shape according to the uneven surface of the insulator 1. At this time, each tension spring 28 also presents a different stretching length according to the relative position of the inspection rod 27 and the integrated board 26. Then, the connecting plate 23 can be moved away from the end of the positioning hoop 21, so that the guide slider 22 moves along the grooves opened on the surfaces of the two closed positioning hoop 21. During the movement, the guide slider 22 will cycle along the grooves on the surface of the positioning hoop 21 to the grooves on the surface of the other positioning hoop 21 and circulate. The insulator 1 moves around the cylinder formed by the two positioning hoops 21, and the positioning hoops 21 will drive the connecting plate 23 and the integrated board 26 to move synchronously. The inspection rod 27 arranged on the surface of the integrated board 26 will surround the insulator 1 and detect various parts of the surface of the insulator 1 during the movement of the integrated board 26. In this process, each inspection rod 27 always keeps a close connection with the insulator 1. When aging and leakage occur somewhere on the surface of the insulator 1, the inspection rod 27 will conduct electricity, and the conducted electricity will be transmitted to the indicator light 210 through the resistor 29. The indicator light 210 that is connected to the electricity will light up, indicating that the position pointed by the inspection rod 27 has aged and has leakage.

[0089] Specifically, the positioning mechanism 4 includes:

[0090] A fixing block 41, the fixing block 41 is fixedly connected to one side of the B grip 34;

[0091] A positioning groove 49, which is provided on one side of the connecting plate 23;

[0092] A positioning block 48, the positioning block 48 is inserted and connected inside the positioning groove 49, and the positioning block 48 is inserted and connected to one side of the fixing block 41;

[0093] The moving component is arranged on one side of the positioning block 48 , and is used to move the position of the positioning block 48 .

[0094] It should be noted that the positioning groove 49 is opened on the side of the connecting plate 23 close to the B handle 34, and the fixed block 41 is fixedly connected to the side of the B handle 34 close to the connecting plate 23. When the position of the positioning hoop 21 is moved, the connecting plate 23 is moved to be parallel to the B handle 34, and then the positioning block 48 is moved to the inside of the positioning groove 49. The connecting plate 23 cannot continue to rotate through the obstruction of the positioning block 48, thereby avoiding the connection plate 23 and the guide slider 22 from rotating when the multiple positioning hoops 21 are separated.

[0095] Specifically, the mobile components include:

[0096] A driving plate 45, the driving plate 45 is fixedly connected to one side of the positioning block 48;

[0097] A connecting block 46, the connecting block 46 is fixedly connected to the front side of the driving plate 45;

[0098] A push plate 47, which is fixedly connected to the front side of the connecting block 46, and is used to drive the driving plate 45 and the positioning block 48 to move;

[0099] The pushing spring 43 is disposed on one side of the driving plate 45 , and is used to push the driving plate 45 .

[0100] Specifically, a cavity 42 is opened in the middle of the fixing block 41 , the driving plate 45 and the pushing spring 43 are both inserted and connected inside the cavity 42 , a sliding hole 44 is opened on the inner wall of the front side of the cavity 42 , and the connecting block 46 is inserted and connected inside the sliding hole 44 .

[0101] It should be noted that the driving plate 45 is adapted to the cavity 42, so that the driving plate 45 can move inside the cavity 42. The sliding hole 44 and the connecting block 46 are used to connect the driving plate 45 located inside the cavity 42 with the pushing plate 47 located outside the cavity 42, so that the driving plate 45 located inside the cavity 42 is driven to move by the pushing plate 47 located outside the cavity 42, and the positioning block 48 is driven to move by the driving plate 45; the pushing spring 43 is used to push the driving plate 45, so as to avoid the driving plate 45 and the positioning block 48 from moving at will.

[0102] Furthermore, before the device needs to be fixed on the insulator 1, the driving plate 45 and the positioning block 48 are first driven to move toward the side of the driving spring 43 by the pushing plate 47, and then the connecting plate 23 is driven to rotate by the guide slider 22, and the positioning groove 49 on the connecting plate 23 is aligned with the positioning block 48, and finally the movement of the pushing plate 47 is released, and the force of the pushing spring 43 to restore the deformation is used to drive one end of the positioning block 48 to move to the inside of the positioning groove 49, and the positioning block 48 is used to limit the position of the connecting plate 23 and the guide slider 22, thereby avoiding the connection plate 23 and the guide slider 22 from rotating when the multiple positioning hoops 21 are separated.

[0103] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
