If there is a problem with the insulation performance, it will pose a great threat to the live workers. Therefore, before live work, the insulation performance of the insulating clothing must be checked.

[0003] The patent with announcement number CN108427036B discloses a device for detecting the insulation resistance between layers of an insulating suit, which comprises a conductive rotating rod, a resistance detection meter and a clamping mechanism; two clamps are respectively placed on the front and back sides of the insulating suit to contact the surface and the inside of the insulating suit, so that the conductive rod is tightly attached to the insulating suit, and the handle is pushed to rotate the bearing, and the conductive rod is pushed to the detection position of the insulating suit through the rotation of the bearing, so that the insulation resistance between layers can be detected.

During the rotation process, the second rod drives the first rod to rotate through the linkage assembly. The rotation of the first rod causes the notches of the first spiral groove and the second spiral groove to exchange positions.

[0015] In the above technical scheme, the present invention provides an insulating clothing interlayer and surface insulation resistance detection device, in which the sleeves of the insulating clothing are put on the support plate, and the worker pulls the sliding rod to make the sliding rod slide relative to the fixed rod.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] See also Figure 1-9 The embodiment of the present invention provides an insulating clothing interlayer and surface insulation resistance detection device, comprising a fixed rod 1, a first set of rods 2, a sliding rod 11 and a detection member 3, wherein the first set of rods 2 is rotatably connected to the fixed rod 1, and an arc-shaped support plate 21 for stretching the sleeve 101 of the insulating clothing is coaxially fixedly connected to the first set of rods 2, and a first spiral groove 22 is provided inside the first set of rods 2; the sliding rod 11 is slidably connected to the fixed rod 1, and a ball 111 that slidably cooperates with the first spiral groove 22 is provided on the sliding rod 11; the detection member 3 is rotatably connected to the sliding rod 11, and the detection member 3 is slidably connected to the first set of rods 2 along the axial direction of the first set of rods 2; the sliding rod 11 is relatively fixed During the sliding process of the rod 1, the detection member 3 is driven to move along the length direction of the sleeve 101 and rotate along the circumference of the sleeve 101. Specifically, the detection unit 31 includes a clamping rod 311, a U-shaped frame 312 and a detection roller 313. The clamping rod 311 is fixedly connected to the U-shaped frame 312, and the detection roller 313 is rotatably connected to the U-shaped frame 312; a rubber block 32 is fixedly connected to the clamping rod 311 close to the first set of rods 2, and a card slot 321 is provided on the rubber block 32, and an elastic sheet 33 is provided between the two clamping rods 311; a bearing plate 12 is fixedly connected to the fixing rod 1, and at least one clip for clamping and fixing the insulating clothing sleeve 101 is provided on the bearing plate 12.

[0022] During the working process, the worker puts the sleeve 101 of the insulating suit on the support plate 21, and clamps and fixes the sleeve 101 through the clip on the supporting plate 12 (not shown in the figure, this is the prior art and will not be described in detail here), and the worker pulls the sliding rod 11 to make the sliding rod 11 slide relative to the fixed rod 1. During the sliding process of the sliding rod 11, the ball 111 on the sliding rod 11 rolls with the spiral groove in the first set of rods 2 to drive the first set of rods 2 to rotate. While the sliding rod 11 slides relative to the fixed rod 1, it will drive the detection piece 3 to move along the axial direction of the first set of rods 2, and the rotation of the first set of rods 2 will drive the detection piece 3 to make a circular motion around the support rod (the clip is within the rotation range of the detection piece 3 and does not contact the frame), and the detection piece 3 is subjected to the joint action of the sliding rod 11 and the first set of rods 2. In this process, the detection piece 3 spirally moves around the sleeve 101 of the insulating suit. The component 3 can pass through different circumferential positions and different axial positions of the sleeve 101; wherein, a rotating sleeve is fixedly connected to the first set of rods 2, and a connecting block is fixedly connected to the rotating sleeve. The connecting block is slidably connected to the clamping rod 311 to realize the rotation of the first set of rods 2 while driving the detection component 3 to rotate without affecting the sliding of the detection component 3 relative to the first set of rods 2. The positive terminal and the negative terminal are electrically connected to the detection rollers 313 in the two detection units 31 respectively to realize the resistance detection of the insulating clothing. One of the clamping rods 311 is closed with the other clamping rod 311 through the slot 321 on the rubber block 32. Under the joint action of the two clamping rods 311, the two detection rollers 313 clamp the clothes for detection, and after being separated from the slot 321, the elastic sheet 33 makes one of the clamping rods 311 away from the other clamping rod 311.

[0023] In the above technical scheme, the present invention provides an insulating clothing interlayer and surface insulation resistance detection device, so that when the worker inserts the detection piece 3 into the insulating clothing sleeve 101 for detection, the movement path of the detection piece 3 for detecting the insulating clothing sleeve 101 is increased, thereby realizing that in the process of a single insertion of the detection piece 3, the insulating clothing sleeve 101 can be detected at different axial positions and different axial positions, and the worker only needs to push the slide bar 11, which simplifies the worker's operating steps and improves the worker's detection efficiency.

[0024] As a further embodiment of the present invention, refer to Figure 4 , Figure 5 , Figure 6 as well as Fig. 9A second spiral groove 23 is provided in the first sleeve rod 2, and the spiral directions of the first spiral groove 22 and the second spiral groove 23 are the same. The fixed rod 1 is rotatably connected with a second sleeve rod 4, and a vertical groove 41 and a third spiral groove 42 are provided inside the second sleeve rod 4. When the ball 111 on the slide rod 11 is disengaged from the first spiral groove 22, the slide rod 11 continues to slide so that the ball 111 enters the vertical groove 41 of the second sleeve rod 4. The slide rod 11 drives the second sleeve rod 4 to rotate through the rolling cooperation between the ball 111 and the third spiral groove 42. During the rotation process, the second sleeve rod 4 drives the first sleeve rod 2 to rotate through the linkage assembly 5. The rotation of the first sleeve rod 2 causes the notches of the first spiral groove 22 and the second spiral groove 23 to exchange positions. During the process of the ball 111 disengaging from the third spiral groove 42, the second sleeve rod 4 rotates relative to the fixed rod 1 while the first sleeve rod 2 does not rotate. The cam 52 is rotatably connected to the second set of rods 4 by a rotating shaft, and the cam 52 has a first position in which one end of the cam 52 extends into the second set of rods 4, and a second position in which both ends of the cam 52 are close to the outer wall of the second set of rods 4; one end of the cam 52 is slidably connected to the second set of rods 4 along the axial direction of the second set of rods 4; the cam 54 is fixedly connected to the other end of the cam 53, and the cam 54 is rotatably connected to the cam 52; in the process of the elastic member restoring the deformation, the cam 52 is driven to switch from the second position to the first position, and the elastic member includes a spring, one end of which is connected to the rotating shaft of the cam 52, and the other end is connected to the second set of rods 4.

[0025] Based on the movement path of the detection member 3, the slide bar 11 continues to slide relative to the fixed rod 1, the slide bar 11 disengages from the first spiral groove 22, and then the slide bar 11 enters the second set of rods 4 and the ball 111 on the slide bar 11 enters the vertical groove 41 in the second set of rods 4. During the movement of the slide bar 11 in the second set of rods 4, the slide bar 11 abuts against the rotating rod 52 to rotate the rotating rod 52. The rotation of the rotating rod 52 drives the inner rod of the telescopic rod 53 to move into the outer rod of the telescopic rod 53 (the telescopic rod 53 includes an outer rod and an inner rod, the outer rod is slidably connected to the second set of rods 4, and the inner rod is fixedly connected to the abutting rod 54), and at the same time, the telescopic rod 53 moves along the axial direction of the second set of rods 4, so that the abutting rod 54 can abut against the connecting rod 53. Rod 51, when the ball 111 on the slide bar 11 cooperates with the third spiral groove 42, the second set of rods 4 rotates relative to the fixed rod 1, and the rotation of the second set of rods 4 drives the abutment rod 54 to abut the connecting rod 51, so that the first set of rods 2 rotates (the fixed rod 1 passes through the second set of rods 4, and during the rotation of the second set of rods 4, the slide bar 11 first abuts the rotating rod 52 so that the abutment rod 54 can abut the connecting rod 51, and as the second set of rods 4 rotates, the slide bar 11 will stop abutting the rotating rod 52, but the fixed rod 1 can continue to maintain the state of abutting the rotating rod 52, thereby allowing the abutment rod 54 to maintain abutment against the connecting rod 51), the rotation of the first set of rods 2 drives the detection member 3 to rotate 180 degrees relative to the sleeve 101, and the first set of rods 2 rotates to rotate 180 degrees. During the return stroke of the ball 111 relative to the third spiral groove 42, the second set of rods 4 rotate in the opposite direction (refer to the first rotation of the second set of rods 4), but the abutment rod 54 does not abut against the connecting rod 51, so that the first set of rods 2 does not rotate, and the detection member 3 only moves vertically. During the rotation of the first set of rods 2, the notch positions of the first spiral groove 22 and the second spiral groove 23 are alternated, and then during the return stroke of the slide bar 11, the second set of rods 4 rotates and the fixed rod 1 abuts and rotates back to the slide bar 11 abutting the rotating rod 52, and the rotating rod 52 further stops the slide bar 11 abutting the rotating rod 52, and the rotating rod 52 is acted upon by the clockwork spring so that the rotating rod 52 switches from the second station to the first station, and then the ball on the slide bar 11 111 enters the second spiral groove 23, at which time the detection piece 3 changes from the position where the first spiral movement ends. During the cooperation between the ball 111 and the second spiral groove 23, the return path of the detection piece 3 changes relatively, so that the detection piece 3 can detect more positions of the insulating clothing sleeve 101, further reducing the frequency of the detection piece 3 being inserted into the sleeve 101. It is worth mentioning that an elastic piece can be arranged between the second set of rods 4 and the fixed rod 1 to ensure that the vertical groove 41 on the second set of rods 4 can stay in the same position and will not be misaligned due to accidental rotation. In addition, the first spiral groove 22 and the second spiral groove 23 are on the same diameter of the end face of the first set of rods 2.

[0026] Among them, a hemispherical shell 13 is fixedly connected to the fixed rod 1, and the hemispherical shell 13 can make it easier for the sleeve 101 to be put on the support plate 21; a movable sleeve 6 is rotatably connected to the sliding rod 11, and a connecting rod 61 is fixedly connected to the movable sleeve 6, and the connecting rod 61 is fixedly connected to the detection member 3. The movable sleeve 6 is sleeved on the side of the fixed rod 1, and the fixed rod 1 passes through the first set of rods 2 and the second set of rods 4, so that the first set of rods 2 and the second set of rods 4 can rotate relative to the fixed rod 1. By arranging the fixed rod 1 within the range surrounded by the movable sleeve 6, the fixed rod 1 can achieve the connection of various components without affecting the spiral movement of the detection member 3. In addition, the detection member 3 can be moved from the first set of rods 2 and the sliding rod 11 (the clamping rod 311 is slidably connected to the connecting block, but the connecting block can be detachably connected to the first set of rods 2 by means of buckles, etc., and the clamping rod 311 and the movable sleeve 6 can also be detachably connected by means of buckles), a single detection component 3 can detect the entire insulating suit, and each U-shaped frame 312 can be provided with two detection rollers 313. The spacing between the two detection rollers 313 on any U-shaped frame 312 is two centimeters, and the length of the insulating suit that fits any detection roller 313 is also two centimeters. Rubber washers are provided at both ends of the rotating shaft of the detection roller 313, which does not affect the rotation of the detection roller 313 relative to the U-shaped frame 312 while also ensuring tension between the relative detection rollers 313.

[0027] As another embodiment provided by the present invention, the detection piece 3 includes two groups of detection units 31, the detection unit 31 includes a clamping rod 311, a U-shaped frame 312 and a detection ball 314, the clamping rod 311 is fixedly connected to the U-shaped frame 312, and the detection ball 314 is rollingly connected to the U-shaped frame 312; a rubber block 32 is fixedly connected to the clamping rod 311 close to the first set of rods 2, and a slot 321 is provided on the rubber block 32, and an elastic sheet 33 is arranged between the two clamping rods 311. The rolling of the detection ball 314 can reduce the resistance of the detection piece 3 to move in different directions of the insulating suit, and while the detection piece 3 is moved more easily, the wear of the contact parts between the detection piece 3 and the insulating suit can also be reduced.

[0028] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
