Description

Technical Field

[0001] The utility model relates to the technical field of lightning arresters, and particularly relates to a lightning arrester detection device. Background Art

[0002] A lightning arrester has non-linear characteristics. Within a certain range, its resistance value shows a non-linear state with the change of voltage. When overvoltage occurs in the power system, the resistance value of the lightning arrester will suddenly become smaller, thereby protecting electrical equipment from the influence of overvoltage. And the voltage that each lightning arrester can withstand is also different. The number and quality of the internal resistor chips of the lightning arrester during the production process affect the size of the resistance value. Therefore, after production, the lightning arrester will be detected and classified according to the size of the resistance value. Usually, manual detection is used. However, only one lightning arrester can be clamped for detection at a time, and caution is required during the disassembly and assembly of the lightning arrester to prevent electric shock, which increases the detection time and thus affects the factory efficiency of the lightning arrester. Summary of the Utility Model

[0023] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical solutions of the present utility model will be further described.

[0024] As Figures 1-4 shown, a lightning arrester detection device includes a lightning arrester body 3 and testing ends 31 provided at both ends of the lightning arrester body 3, and further includes:

[0025] Chassis 1;

[0026] A rotating shaft 5, which is rotatably connected to the center of the chassis 1. A first turntable 4 and a second turntable 7 are sequentially arranged on the rotating shaft 5. Corresponding clamping grooves 6 are circumferentially arrayed on both the first turntable 4 and the second turntable 7;

[0027] A clamping unit 8, which is arranged on one side of the clamping groove 6 and is matched with the lightning arrester body 3;

[0028] A testing unit 2, which is arranged on the chassis 1. The testing unit 2 includes a testing tip 29, and the testing tip 29 is matched with the testing end 31.

[0029] Specifically, according to the size of the lightning arrester body 3, the distance between the first turntable 4 and the second turntable 7 can be adjusted. Multiple clamping grooves 6 can clamp multiple groups of lightning arrester bodies 3 at one time through the clamping unit 8 for testing. At the same time, the rotating shaft 5 rotates intermittently. When the rotating shaft 5 stops, the testing unit 2 will test the lightning arrester body 3. The tested lightning arrester body 3 can be removed and replaced, so as to improve the testing efficiency and reduce the risk of electric shock to workers.

[0030] As a further embodiment provided by the present utility model, a first gear 51 and a second gear 53 that are meshed with each other are sequentially rotatably arranged on the chassis 1. A motor 52 that is matched with the first gear 51 is arranged on the chassis 1. The second gear 53 is engaged with the rotating shaft 5. The model of the motor 52 is MHMF042L1U2M2, and it outputs by using the belt age, so as to drive the first gear 51 to mesh with the second gear 53 to rotate, that is, to make the rotating shaft 5 rotate on the chassis 1.

[0031] As a further embodiment provided by the present utility model, a square groove 54 is formed on the rotating shaft 5, the first turntable 4 slides within the square groove 54, and a locking member 41 matching with the square groove 54 is arranged on the first turntable 4. The position of the first turntable 4 sliding on the rotating shaft 5 can be controlled according to the size of the lightning arrester body 3, so as to adjust the distance between the first turntable 4 and the second turntable 7, and the first turntable 4 is fixed to the rotating shaft 5 through the locking member 41.

[0032] As a further embodiment provided by the present utility model, the testing unit 2 further includes a support plate 24, a bottom plate 21 and support columns 25 arranged on the bottom plate 21. The support plates 24 are symmetrically arranged on the support columns 25. A slide bar 27 is slidably arranged on the support plate 24. A spring 28 is arranged between the slide bar 27 and the support plate 24. The testing tip 29 is clamped within the slide bar 27. The bottom plate 21 is matched with the bottom frame 1. A chute 210 is formed on the bottom plate 21, and the support columns 25 can move within the chute 210 to adjust the distance between the support columns 25 and the first turntable 4 and the second turntable 7. When the lightning arrester body 3 rotates on the first turntable 4 and the second turntable 7, the testing end 31 of the lightning arrester body 3 contacts the testing tip 29, which will push the testing tip 29 to slide axially until the lightning arrester body 3 is perpendicular to the testing tip 29, and the spring 28 will pull back the slide bar 27, improving the contact effect of the testing tip 29 on the lightning arrester body 3.

[0033] As a further embodiment provided by the present utility model, support blocks 23 are symmetrically arranged on the support columns 25. A first screw rod 26 is arranged between the support blocks 23. The first screw rod 26 is threadedly connected with the support plate 24. The first screw rod 26 is threadedly connected with one of the support plates 24, and the other support plate 24 is clamped on the screw rod. Rotating the first screw rod 26 can make the upper first support plate 24 slide axially, so as to adjust the distance between the two support plates 24, and different specifications of lightning arrester bodies 3 can be tested in this way.

[0034] As a further embodiment provided by the present utility model, a lever 231 is arranged on the support block 23. The lever 231 is threadedly connected with the support block 23. After the support block 23 is positioned on the support column 25, the lever 231 is swung to fix the support block 23 to the support column 25.

[0035] As a further embodiment provided by the present utility model, the clamping unit 8 further includes a base 81 and a second screw rod 82 arranged within the support block 23. A clamping block 83 is threadedly connected to the second screw rod 82. A rubber block 84 is clamped on the clamping block 83. The rubber block 84 improves the fixing effect on the lightning arrester body 3, and at the same time, the insulating material makes the testing safer. Rotating the second screw rod 82 makes the two clamping blocks 83 slide relatively or in opposite directions within the base 81, thereby adjusting the distance between the rubber blocks 84 to adapt to lightning arrester bodies 3 of different sizes.

[0036] As an embodiment further provided by the present utility model, an inclined portion 841 is provided on the rubber block 84. When the arrester body 3 is snapped into the clamping unit 8, its test end 31 will be snapped between the two rubber blocks 84 along the inclined portion 841.

[0037] Working principle: The motor 52 meshes with the second gear 53 through the first gear 51 to drive the rotating shaft 5 to slowly rotate. Workers snap the arrester body 3 into the rubber block 84 one by one from the opposite end of the test unit 2. The first turntable 4 and the second turntable 7 move the arrester body 3 to directly below the test tip 29. When the arrester body 3 contacts the test tip 29, the elastic force of the spring 28 pulls the slide bar 27 to slide axially, so that the test tip 29 can better contact the test end 31. During the test, the value will be reflected on the test meter 22, which is convenient for workers to read and judge whether it is qualified, improving the efficiency of arrester testing and also improving the safety guarantee for workers.

[0038] Regarding the technical solution of the present utility model above, in view of the technical problem that the prior art solution is too single, a solution significantly different from the prior art is provided. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented using the prior art, and will not be elaborated here.

[0039] The technical solutions in the above embodiments have clearly and completely described the content of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.
