Description

Technical Field

[0001] The utility model relates to the technical field of insulating glove detection, in particular to a voltage withstand detection device for insulating gloves. Background Technique

[0002] Insulating gloves, also known as high-temperature resistant gloves and high-voltage insulating gloves, are made of natural rubber and are five-finger gloves formed by pressing sheets, molding, vulcanizing or dipping molds with insulating rubber or latex. They are mainly used for electrical work. Insulating gloves are protective equipment to prevent operators from getting an electric shock. Insulating gloves generally need to be subjected to a voltage withstand test regularly and can only be used after passing the test to ensure personal safety.

[0003] The traditional voltage withstand detection method is to clamp the insulating glove with a fixed clamp on a frame, then place the frame in a water bucket filled with water, immerse the lower half of the insulating glove in the water, inject water into the insulating glove, and simultaneously energize the water in the bucket and the insulating glove to test its voltage withstand.

[0004] However, after the glove is filled with water, when clamping equipment such as a fixed clamp is used for clamping, the glove may fall off due to insufficient clamping force, thus affecting the voltage withstand test. Moreover, the clamping method and operations such as water injection and power-on are relatively cumbersome. When conducting batch voltage withstand experiments, this operation method becomes time-consuming and laborious, with low efficiency. At this time, a voltage withstand detection device for insulating gloves is urgently needed to solve the above problems. Content of the Utility Model

Specific implementation mode

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 3 , in the embodiment proposed in this application: a voltage withstand testing device for insulating gloves, including a testing table 1, on the upper side of the testing table 1 there is a water tank 2 with an upward opening, inside the water tank 2 there is a fixed conductive block 21, on the outer side wall of the water tank 2 corresponding to the conductive block 21 there is a cable insertion port 22, vertically arranged on the testing table 1 is a support column 3, the support column 3 is located at the rear side of the water tank 2, at the top of the support column 3 there is a horizontally fixed cross plate 4, on the lower side of the cross plate 4 corresponding to the water tank 2 there is a vertically arranged sleeve block 5, inside the sleeve block 5 there are inserted a water inlet pipe 6 and a conductive rod 7, the water inlet pipe 6 is communicated with the external water supply system, the conductive rod 7 is electrically connected with the external power system, on the left and right side walls of the sleeve block 5 there are movably arranged adjusting blocks 8, on the opposite sides of the two adjusting blocks 8 there are respectively provided anti-slip pads 85 to increase the friction during fixation, inside the sleeve block 5 corresponding to the two adjusting blocks 8 there is a drivingly connected adjusting structure 9;

[0021] By setting the sleeve block 5 to cooperate with the adjusting structure 9 to adjust the adjusting block 8, the tested insulating gloves can be quickly fixed, and at the same time, the setting of the adjusting structure 9 can make it applicable to the detection of insulating gloves of different sizes, and the setting of the water inlet pipe 6 and the conductive rod 7 and the start of external control realize the rapidity and convenience of the test, saving time and effort and having high efficiency.

[0022] In another embodiment, refer to Figures 1 to 3 , the adjusting structure 9 includes a threaded rod 91 vertically arranged. The threaded rod 91 is arranged above the cross plate 4. The threaded rod 91 passes through the cross plate 4 downward and extends into the sleeve block 5. The threaded rod 91 is threadedly connected to the cross plate 4 and the sleeve block 5. A first moving cavity 51 is formed inside the sleeve block 5 corresponding to one end of the threaded rod 91 located inside the sleeve block 5. A pressing block 92 slidably connected thereto is arranged at the lower end of the threaded rod 91 corresponding to the first moving cavity 51. The pressing block 92 is rotatably connected to the lower end of the threaded rod 91. A rotation limiting block 93 is arranged at the lower end of the threaded rod 91. A rotation limiting groove 94 rotatably connected thereto is formed in the pressing block 92 corresponding to the rotation limiting block 93. Since the lower end of the threaded rod 91 is rotatably connected to the pressing block 92, when the threaded rod 91 rotates to move up and down to drive the pressing block 92 to move up and down, the pressing block 92 will not rotate accordingly;

[0023] In this embodiment, the pressing block 92 is drivingly connected to two adjusting blocks 8. Two connecting rods 81 are horizontally fixed at one end of the two adjusting blocks 8 facing the inside of the sleeve block 5. The two connecting rods 81 extend into the first moving cavity 51 and are respectively abutted against the left and right sides of the pressing block 92. The two connecting rods 81 are slidably connected to the sleeve block 5. First inclined surfaces 95 inclined inward from top to bottom are respectively arranged at the left and right sides of the pressing block 92 corresponding to the connecting rods 81. Second inclined surfaces 82 abutted against the first inclined surfaces 95 are arranged at the two connecting rods 81 corresponding to the first inclined surfaces 95. Second moving cavities 52 are respectively formed inside the sleeve block 5 corresponding to the parts of the two connecting rods 81 located inside the sleeve block 5. Limiting blocks 83 slidably connected to the second moving cavities 52 are respectively arranged at one ends of the two connecting rods 81 located in the second moving cavities 52 facing each other. Springs 84 are respectively arranged in the two second moving cavities 52. The two springs 84 are respectively arranged at the sides of the two limiting blocks 83 facing away from each other and sleeved on the corresponding connecting rods 81;

[0024] Due to the arrangement of the inclined surfaces, when the pressing block 92 presses down, the two connecting rods 81 on both sides can be extruded outwards and the springs 84 can be compressed, so that the two adjusting blocks 8 protrude outwards. When the pressing block 92 rises, the two adjusting blocks 8 are contracted inwards through the reset of the springs 84 to adapt to the diameter of the opening of the insulating glove to be measured and fix it.

[0025] Working principle: For an insulating glove withstand voltage detection device, during the test, the opening of the insulating glove to be tested is sleeved on the sleeve block 5, and the lower end of the insulating glove is immersed in the water tank 2. By turning the threaded rod 91 above the cross plate 4, the height of the pressing block 92 is adjusted, so as to adjust the protruding length of the two adjusting blocks 8 abutted against it to adapt to the diameter of the opening of the insulating glove to be measured. After the fixing is completed, the external control water supply system injects water into the glove through the water inlet pipe 6, and the water tank 2 and the conductive rod 7 are simultaneously energized to test the withstand voltage performance of the insulating glove.
