Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glove insulation test equipment, in particular to a test device for insulating gloves. BACKGROUND

[0002] Insulating gloves, also known as high-voltage insulating gloves, are made of natural rubber and are formed by pressing, molding, vulcanizing or dipping of insulating rubber or latex. They are suitable for use in the electric power industry, automobile and mechanical maintenance, chemical industry and precision installation. Insulating gloves are an important part of individual protective equipment for insulation protection. Therefore, after production, insulating gloves are usually tested for insulation using a pressure tester to prevent unqualified products from entering the market.

[0003] The existing pressure tester generally includes a water tank, a conductive bucket, a test stand and a conductive chain. Before testing, the conductive bucket is placed in the water tank, and then the insulating gloves are fixed in the conductive bucket using a clamp. Then water is injected into the water tank, the conductive bucket and the insulating gloves. During testing, one end of the conductive chain is placed in the insulating gloves and the other end is hung on the unhooker of the test stand. However, during the process of injecting water into the conductive bucket and the insulating gloves, the water is usually injected into the conductive bucket and the insulating gloves in sequence by a person using a water pipe, which consumes time and prolongs the testing time. Moreover, when the water pipe is used to inject water into the conductive bucket from the opening at the top of the conductive bucket, the water flowing out of the water pipe will inevitably cause the water in the conductive bucket to splash, which will cause the part of the insulating gloves exposed to the water surface in the conductive bucket to be easily wetted by the water splash, thereby affecting the test results of the insulating gloves.

By using the three clips 9 to clamp the side walls of the insulating gloves, the opening of the insulating gloves can be opened and The water outlet of the quasi-water injection pipe 8; a cylinder 10 is provided on the top of the test stand 1, and the output end of the cylinder 10 is connected to the top of the support rod 6. The support rod 6 is driven down by the cylinder 10, and the insulating gloves clamped by the clamp 9 can be driven down; the unhooker 2 and the conductive bucket 4 are each provided with five and correspond one to one with the five support columns 7. A water injection mechanism is provided at the bottom of the conductive bucket 4, and a water injection port 11 connected to the water injection mechanism is provided at the bottom of the water tank 3. The water injection port 11 injects water into the conductive bucket through the water injection mechanism; a first control valve is provided in the water injection pipe 8, and a second control valve is provided in the water injection port 11. The cylinder 10, the first control valve and the second control valve are all electrically connected to the controller, and the two ends of the transformer are electrically connected to the controller and the test stand 1 respectively. The controller controls the opening or closing of the first control valve, the second control valve and the cylinder 10, and controls the transformer to input the test voltage to the test stand 1.

[0031] The opposite sides of the test stand 1 are both sliding rods 19 fixedly connected to the water trough 3, and both ends of the support rod 6 are sliding grooves 20 that slide with the sliding rod 19, which can improve the stability of the support rod 6 during the descent process; a soft pressure head 23 is provided at the bottom of the connecting plate 21 away from the end of the support column 7, and the soft pressure head 23 is aligned with the top of the side wall of the conductive bucket 4. The soft pressure head 23 will follow the support column 7 to descend, and then the conductive bucket 4 will be pressed tightly into the water trough 3 through the soft pressure head 23 to avoid affecting the docking of the water injection port 11 and the water injection mechanism, and affecting the water inflow from the bottom of the conductive bucket 4; a first connecting pipe is provided inside the support rod 6 along the length direction of the support rod 6, and one end of the water injection pipe 8 passes through the top of the support column 7. The first hose 24 is fixed to the side of the top of the test stand 1, and one end of the first hose 24 is inserted into the support rod 6 and is connected with the first connecting pipe. The other end is connected with an external water source. The water from the external water source enters the first connecting pipe through the first hose 24, and then the water is diverted to the water injection pipe 8; a second connecting pipe extending along the length direction of the water sink 3 is provided inside the bottom of the water sink 3, and the water injection port 11 is connected with the second connecting pipe. A water receiving pipe 25 connected to the second connecting pipe is provided on the side of the water sink 3. The pipe of the external water source is connected to the water receiving pipe 25. The water from the external water source enters the second connecting pipe through the water receiving pipe 25, and then the water is diverted to the water injection port 11.

[0032] The water injection mechanism includes a spring 12 and a piston 13. The piston 13 is a frustum structure that is wide at the top and narrow at the bottom. A positioning hole 14 that is adapted to the water injection port 11 is provided at the bottom of the conductive barrel 4. The positioning hole 14 can be limited by the water injection port 11, and then the conductive barrel 4 can be limited so that the side wall of the conductive barrel 4 can be better aligned with the soft pressure head 23. A piston hole 15 that is adapted to the piston 13 is provided at the bottom of the conductive barrel 4. The piston hole 15 is communicated with the positioning hole 14. A bracket 16 is provided on the bottom of the conductive barrel 4. One end of the spring 12 is fixedly connected to the top of the piston 13, and the other end is fixed to the bracket 16. The frame 16 is fixedly connected, and the water flowing out of the water injection port 11 can push open the piston 13 (so that the spring 12 is compressed), allowing the water to flow into the conductive barrel 4 along the gap between the piston 13 and the piston hole 15. After the water injection port 11 stops injecting water into the positioning hole 14, the piston 13 is pushed to block the piston hole 15 under the elastic action of the spring 12; the outer surface of the water injection port 11 is wrapped with a sealing gasket 17, and the positioning hole 14 is provided with a sealing groove 18 adapted to the sealing gasket 17, which can improve the sealing performance and prevent the water flowing out of the water injection port 11 from seeping through the gap between the water injection port 11 and the positioning hole 14.

[0033] The water injection pipe 8 is connected to a second hose 26, which can be placed in the insulating glove clamped by the clip 9, making it convenient for the water injection pipe 8 to inject water into the insulating glove and preventing water from flowing out of the water injection pipe 8 from splashing the insulating glove; a first pull rope 27 is fixedly connected to the water injection pipe 8, and the other end of the first pull rope 27 is fixedly connected to a first float 28. A second pull rope 29 is fixedly connected to the inner wall of the conductive bucket 4, and the other end of the second pull rope 29 is fixedly connected to a second float 30. The first float 28 can be placed in the insulating glove, and the second float 30 can be placed in the conductive bucket 4. During the process of filling water into the insulating glove and the conductive bucket 4, the liquid level height in the insulating glove and the conductive bucket 4 can be more easily known by observing the height of the first float 28 and the second float 30; self-locking universal wheels 31 are provided at the four corners of the bottom of the water tank 3 for easy transfer; a drain pipe 32 is provided at the bottom of the water tank 3 for draining the water in the water tank 3.

[0034] Working principle:

[0035] like Figure 1-7 As shown, before using the test device to test the insulating gloves, align the conductive bucket 4 with the water inlet 11 and place it in the water tank 3, so that the positioning hole 14 of the conductive bucket 4 is docked with the water inlet 11. After the conductive bucket 4 is placed, the side walls of the insulating gloves are clamped by three clips 9 distributed around the circumference, so that the opening of the insulating gloves can be stretched open and aligned with the water outlet of the water injection pipe 8. Then, the second hose 26 and the first float 28 are placed in the insulating gloves. After the insulating gloves are fixed, the cylinder 10 is started by the controller, and the output end of the cylinder 10 will drive the support rod 6 to descend, and then the insulating gloves clamped by the clip 9 and the soft pressure head 23 will descend, so that the insulating gloves can fall into the conductive bucket 4, and the soft pressure head 23 will press the top of the side wall of the conductive bucket 4, and then water can be poured into the water tank 3. After the water tank 3 is filled with water, the first control valve and the second control valve are opened by the controller. Water from the external water source enters the first connecting pipe through the first hose 24 and is diverted to the water injection pipe 8, and then flows into the insulating gloves through the second hose. Water from the external water source enters the second connecting pipe through the water receiving pipe 25 and is diverted to the water injection port 11. The water flowing out of the water injection port 11 can push open the piston 13, allowing the water to flow into the conductive barrel 4 along the gap between the piston 13 and the piston hole 15. The insulating gloves and the conductive barrel 4 are respectively filled with water through the water injection pipe 8 and the water injection port 11 at the same time, saving time and shortening the test time. The water injection port 11 injects water into the conductive barrel 4 from the bottom of the conductive barrel 4, which can prevent the water in the conductive barrel 4 from splashing, and prevent the part of the insulating gloves exposed to the water from being wetted by the splashing, so as not to affect the test results;

[0036] During the process of injecting water into the insulating gloves and the conductive barrel 4, the heights of the first float 28 and the second float 30 are observed, and the closing sequence of the first control valve and the second control valve is controlled by the controller so that the heights of the first float 28 and the second float 30 are basically consistent. During the test, one end of the conductive chain 5 is placed in the insulating glove, and the other end is hung on the dehooker 2 of the test frame 1. After the conductive chain 5 is hung, the transformer is controlled by the controller to input the test voltage to the test frame 1. If the conductive chain 5 on the dehooker 2 falls off, the insulation test of the corresponding insulating glove fails.

[0037] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
