Description

Technical Field

[0001] This invention relates to the field of heat resistance technology for insulating protective covers, specifically a testing device for transparent insulating protective covers. Background Technology

[0002] Transparent insulating protective covers are widely used in the power industry and other fields, and are commonly used at the terminals of surge arresters. They can effectively prevent and avoid power outages and electric shocks caused by damage to power facilities due to various reasons (human contact, electricity theft, contact with small animals or debris, condensation flashover, pollution flashover, salt spray, acid rain and chemical corrosion, etc.) caused by the previously exposed terminals of power equipment. This avoids various losses. Its heat resistance directly determines the safety and service life of use. Therefore, heat resistance testing before leaving the factory is an essential procedure.

[0003] Existing heat resistance testing devices for transparent insulating protective covers have many drawbacks in practical use. For example, a heat resistance performance testing device for insulating protective covers of drop-out arresters (publication number CN114594128B) involves cumbersome loading and unloading operations, requiring workers to insert their hands into the test chamber to complete positioning and disassembly. The high temperature inside the test chamber can easily cause burns to workers, posing a certain safety hazard. Secondly, the disassembly of the insulating protective cover requires the cumbersome process of removing each positioning piece individually, which is time-consuming and labor-intensive, resulting in low overall efficiency of the testing process.

[0004] Based on this, a transparent insulating protective cover testing device is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0005] The purpose of this invention is to provide a transparent insulating protective cover testing device to solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A transparent insulating protective cover testing device includes a test chamber, a heating fan, and a placement and positioning component. The heating fan is installed on the top wall of the test chamber for heating the insulating protective cover placed inside the test chamber. The placement and positioning component is slidably installed on the test chamber for convenient placement of the insulating protective cover. The test chamber has a door installed on the side wall via hinges. The placement and positioning assembly includes a placement plate and a positioning module. Several positioning modules are installed on the side wall of the placement plate. The positioning modules are used to position the insulating protective cover to prevent it from being blown away by the heating fan and affecting the detection. The positioning module includes a positioning rod adapted to the shape of the holes in the insulating protective cover. The positioning rod is rotatably mounted on the side wall of the placement plate for convenient and quick unloading and loading. Several guide rails are provided around the positioning rod. A support rod is connected to the inner wall of the guide rails via a pin. A slider is slidably connected to the inner wall of the guide rails. The slider is connected to the support rod via a pin. The support rod is connected to the support rod via a pin. A spring is fixedly connected between the slider and the inner wall of the guide rails.

[0007] Based on the above technical solutions, the present invention also provides the following optional technical solutions: In one alternative: the positioning rod is fixedly connected to a rotating shaft, the rotating shaft is connected to the placement plate via a bearing, a mating ring is fixedly connected to the periphery of the rotating shaft, and a coil spring is fixedly connected between the mating ring and the placement plate.

[0008] In one alternative: a gear is fixedly connected to the circumference of the rotating shaft, and a rack plate is installed on the bottom wall of the test chamber near the opening, the rack plate meshing with the gear.

[0009] In one alternative: the side wall of the placement plate is provided with a limiting chamfer to limit the maximum rotation angle of the positioning rod.

The sliders are slidably connected to the inner wall of the guide rails.

[0012] In one alternative: several infrared detectors are installed on the side wall of the enclosure door for detecting the heat resistance of the insulating protective cover, and the infrared detectors are electrically connected to an external controller.

[0013] In one alternative: a temperature detector is installed on the side wall of the cabinet door, and the temperature detector is electrically connected to an external controller.

[0014] In one alternative: the test chamber has an exhaust window on its side wall.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a linkage structure between the door and the positioning component, allowing the positioning component to automatically slide out of the test chamber when the door is opened. Both loading and unloading are completed at the test chamber outlet, eliminating the need for workers to insert their hands into the high-temperature test chamber and fundamentally avoiding the safety hazard of high-temperature burns.

[0016] The positioning module of the present invention has a positioning rod that is adapted to the shape of the hole in the insulating protective cover.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-7 As shown, a transparent insulating protective cover testing device includes a test chamber 1, a heating fan 2, and a placement and positioning component 10. The heating fan 2 is provided on the top wall of the test chamber 1 for heating the insulating protective cover placed inside the test chamber 1. The placement and positioning component 10 is slidably provided on the test chamber 1 for convenient placement of the insulating protective cover. A door 3 is installed on the side wall of the test chamber 1 via a hinge. The placement and positioning assembly 10 includes a placement plate 11 and a positioning module. Several positioning modules are installed on the side wall of the placement plate 11. The positioning modules are used to position the insulating protective cover to prevent it from being blown by the heating fan 2 and affecting the detection. The positioning module includes a positioning rod 14 that is adapted to the shape of the holes in the insulating protective cover. The positioning rod 14 is rotatably mounted on the side wall of the placement plate 11 for easy and quick unloading and loading. Several guide rails 20 are provided around the positioning rod 14. The inner wall of the guide rails 20 is connected to a support rod 18 via a pin. A slider 21 is slidably connected to the inner wall of the guide rails 20. The slider 21 is connected to a support rod 19 via a pin. The support rod 19 is connected to the support rod 18 via a pin. A spring is fixedly connected between the slider 21 and the inner wall of the guide rails 20.

[0028] Place the heads of several insulating protective covers against the placement plate 11, then align the holes of the insulating protective covers with the positioning rod 14 and insert them. During the insertion process, support rod 18 and support rod 29 first move closer to the positioning rod 14. After support rod 18 and support rod 2 19 enter the insulating protective cover, they are reset under the action of the spring and fixed inside the insulating protective cover, thus quickly completing the positioning and fixing of the insulating protective cover. The operation is quick and convenient.

[0029] The material is loaded at the outlet near test chamber 1, which eliminates the need for staff to put their hands inside test chamber 1. This makes loading quick and convenient, and also safer, avoiding burns.

[0030] In one embodiment, the positioning rod 14 is fixedly connected to a rotating shaft 16, the rotating shaft 16 is connected to the placement plate 11 through a bearing, a mating ring 23 is fixedly connected to the circumference of the rotating shaft 16, and a coil spring is fixedly connected between the mating ring 23 and the placement plate 11.

[0031] The rotating shaft 16 is driven to return to its original position by the action of the coil spring.

[0032] In one embodiment, a gear 17 is fixedly connected to the circumference of the rotating shaft 16, and a rack plate 9 is installed on the bottom wall of the test chamber 1 near the opening, with the rack plate 9 meshing with the gear 17.

[0033] In one embodiment, the sidewall of the placement plate 11 is provided with a limiting chamfer to limit the maximum rotation angle of the positioning rod 14.

[0034] In one embodiment, a connecting frame 13 is fixedly connected to the side wall of the placement plate 11, and a connecting rod 15 is connected to the connecting frame 13 via a pin. A positioning rod 14 is slidably connected to a push ring 22, and the end of the connecting rod 15 away from the connecting frame 13 is rotatably connected to the push ring 22 via a pin.

[0035] In one embodiment, the side wall of the placement plate 11 is connected to a second connecting rod 8 by a pin, the end of the second connecting rod 8 away from the placement positioning component 10 is connected to a first connecting rod 6 by a pin, and the end of the first connecting rod 6 away from the second connecting rod 8 is connected to the box door 3 by a pin. The staff rotates the door 3 until it closes with the test chamber 1. During the rotation of the door 3, the door 3, through connecting rod 6 and connecting rod 8, causes the placement and positioning component 10 to move synchronously into the test chamber 1 with the insulating protective cover, thus completing the placement of the insulating protective cover.

[0036] When gear 17 moves above rack plate 9, continuing to rotate the door 3 will cause gear 17 to rotate. The rotation of gear 17 drives the rotating shaft 16 and positioning rod 14 to rotate, causing the insulating protective cover to gradually tilt. At the same time, during the rotation of positioning rod 14, connecting rod 3 15 cooperates with push ring 22 to slide on positioning rod 14. During the sliding process of push ring 22, it will squeeze support rod 2 19. At this time, support rod 2 19 is pressed down into guide rail 2 20, and at the same time, it drives support rod 1 18 to press down, automatically releasing the positioning and fixing of support rod 1 18 and support rod 2 19 on the insulating protective cover. With the rotation of positioning rod 14, the insulating protective cover will gradually fall under the action of gravity, and push ring 22 will also cooperate to push the insulating protective cover down. The staff can place a storage box at the falling point in advance to facilitate the insulating protective cover falling into the storage box.

[0037] The inner wall of the test chamber 1 is fixedly connected to two symmetrical guide rails 7, and the side wall of the placement plate 11 is fixedly connected to two symmetrical sliders 12. The sliders 12 are slidably connected to the inner wall of the guide rails 7.

[0038] In one embodiment, several infrared detectors 4 are installed on the side wall of the door 3 for detecting the heat resistance of the insulating protective cover. The infrared detectors 4 are electrically connected to an external controller.

[0039] In one embodiment, a temperature detector 5 is installed on the side wall of the door 3, and the temperature detector 5 is electrically connected to an external controller.

[0040] The heating fan 2 is started to heat the inside of the test chamber 1. The infrared detector 4 collects the deformation data generated by the insulating protective cover under heat and transmits it to the controller. The temperature detector 5 transmits data to the controller to monitor the temperature inside the test chamber 1 at all times.

[0041] In one embodiment, the test chamber 1 has an exhaust window 24 on its side wall.

[0042] The above embodiments disclose a transparent insulating protective cover testing device, the specific working principle and process of which are as follows: S1: The staff first opens the box door 3. During the opening process, the connecting rod 1 6 will pull the connecting rod 2 8. The connecting rod 2 8 will drive the placement positioning component 10 to move along the track of the guide rail 1 7 to the outside of the test box 1. When the placement positioning component 10 has not yet moved above the rack plate 9, the rotation of the box door 3 will stop. S2: Place the heads of several insulating protective covers against the placement plate 11, then align the holes of the insulating protective covers with the positioning rod 14 and insert them. During the insertion process, support rod 18 and support rod 29 first move closer to the positioning rod 14. After support rod 18 and support rod 219 enter the insulating protective cover, they are reset under the action of the spring and fixed inside the insulating protective cover. This quickly completes the positioning and fixing of the insulating protective cover, and the operation is quick and convenient. S3: The staff rotates the door 3 until it closes with the test chamber 1. During the rotation of the door 3, the door 3, through the first link 6 and the second link 8, causes the placement and positioning component 10 to move synchronously into the test chamber 1 with the insulating protective cover, thus completing the placement of the insulating protective cover. S4: Start the heating fan 2 to heat the inside of the test chamber 1. The infrared detector 4 collects the deformation data generated by the insulating protective cover under heat and transmits it to the controller. The temperature detector 5 transmits data to the controller to monitor the temperature inside the test chamber 1 at all times. S5: After the insulation cover test is completed, the staff opens the box door 3 again. During the rotation of the box door 3, the positioning component 10 is simultaneously placed and moves along the track of guide rail 7 towards the outside of the test box 1. When gear 17 moves above rack plate 9, the box door 3 is rotated again, causing gear 17 to rotate. The rotation of gear 17 drives the rotating shaft 16 and positioning rod 14 to rotate, causing the insulation cover to gradually tilt. At the same time, during the rotation of positioning rod 14, connecting rod 3 15 cooperates with push ring 22 to tilt. As the positioning rod 14 slides, the push ring 22 will press the second support rod 19 during the sliding process. At this time, the second support rod 19 is pressed down into the second guide rail 20, which at the same time drives the first support rod 18 to press down, automatically releasing the positioning and fixing of the first support rod 18 and the second support rod 19 to the insulating protective cover. With the rotation of the positioning rod 14, the insulating protective cover will gradually fall down under the action of gravity, and the push ring 22 will also cooperate to push the insulating protective cover down. The staff can place a storage box at the falling point in advance to facilitate the insulating protective cover falling into the storage box. The process does not require manual release of the positioning module. During the rotation of the box door 3, the mechanical structure works together to automatically release the insulation protective cover. There is no need for manual hands to enter the test box 1 to release the insulation protective cover, which avoids the risk of workers being burned and makes unloading faster and more convenient. When reloading, after rotating the door 3 to a certain range, the gear 17 retracts to the back of the rack plate 9, and the rotating shaft 16 is driven to reset under the action of the coil spring. Through the limiting chamfer of the placement plate 11, the positioning rod 14 can only rotate to a certain tilt angle, and the push ring 22 also returns to its original position. Then, the insulating protective cover can be loaded according to the above steps. The loading is also carried out near the outlet of the test box 1, without the need for the staff to put their hands into the test box 1. The loading is quick and convenient, and also safer.

[0043] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
