Description

Technical Field

[0001] This application belongs to the technical field of lightning arresters, and particularly relates to a lightning arrester detection device. Background Art

[0002] Lightning arresters are used to protect electrical equipment from the hazards of high transient overvoltages during lightning strikes, limit the follow current time, and often limit the follow current amplitude. Under normal circumstances, the lightning arrester is in a high-resistance state, and only microampere-level leakage current passes through. When the voltage acting on the lightning arrester reaches the operating voltage of the lightning arrester, the lightning arrester conducts, and a large current passes through the lightning arrester to release the overvoltage energy, limiting the overvoltage to a certain level and protecting the equipment insulation. After releasing the overvoltage energy, the lightning arrester returns to its original state.

[0003] A lightning arrester detection device is a device used to monitor the status of lightning arresters and detect potential hazards. The lightning arrester detection device usually includes a fixture, which is clamped and fixed on the lightning arrester through the fixture. However, the size of the fixture of the existing lightning arrester detection device is usually fixed and only suitable for lightning arresters of specific sizes.

[0030] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0031] Referring jointly to Figures 1 to 8 As shown, according to an embodiment of the present application, a lightning arrester detection device is provided, including a detection rod. The detection rod includes a sliding seat 1 and two clamping jaws 3. A first driving member 16 is arranged on the sliding seat 1. The first driving member 16 is respectively connected to the two clamping jaws 3 to drive the two clamping jaws 3 to slide towards each other or away from each other on the sliding seat 1. A second driving member 32 is arranged on the clamping jaw 3. The second driving member 32 is used to drive the clamping jaw 3 to expand and contract.

[0032] By providing the sliding seat 1, a setting position is provided for the two clamping jaws 3. By arranging the first driving member 16 on the sliding seat 1, the two clamping jaws 3 can be driven to slide towards each other or away from each other on the sliding seat 1, so that the detection device can flexibly adjust the distance between the two clamping jaws 3 according to different specifications of the lightning arrester, so that lightning arresters of different specifications can be firmly fixed by adjusting the distance between the clamping jaws 3, expanding the applicable range of the detection device. By arranging the second driving member 32 on the clamping jaw 3, the clamping jaw 3 can be driven to expand and contract. During the detection process, when encountering a lightning arrester with an irregular shape, the length of the clamping jaw 3 can be adjusted by the second driving member 32 to make the clamping jaw 3 have a larger contact area with the lightning arrester, effectively reducing the shaking and displacement of the device during detection, providing a strong guarantee for obtaining accurate detection data, and significantly improving the stability and accuracy of the detection. During detection, the operator no longer needs to frequently replace the detection equipment to adapt to different lightning arresters. Only by operating the first driving member 16 and the second driving member 32 can the detection device be quickly adjusted to adapt to the lightning arrester to be detected, significantly improving the efficiency of the detection work.

[0033] Among them, the detection rod is a component used for fixedly connecting with the lightning arrester in the lightning arrester detection device. During detection, the operator fixes the detection rod on the lightning arrester, and the parameter information of the lightning arrester is collected by the inductor 332 on the detection rod and transmitted to the detector of the lightning arrester detection device for analysis by the detector.

[0034] Among them, the detection rod is strip-shaped, which is convenient for the operator to hold and operate.

[0035] Among them, the first driving member 16 is connected to the two clamping jaws 3 through a transmission mechanism to drive the two clamping jaws 3 to slide towards each other or away from each other on the sliding seat 1. That is to say, the first driving member 16 is indirectly connected to the two clamping jaws 3.

[0036] The sliding seat 1 includes a hollow seat body 11. A bidirectional threaded rod 131 is arranged inside the seat body 11. The bidirectional threaded rod 131 includes a first threaded section and a second threaded section. The thread rotation directions of the first threaded section and the second threaded section are opposite. One of the clamping jaws 3 is arranged on the first threaded section, and the other clamping jaw 3 is arranged on the second threaded section. The first driving member 16 is connected to the bidirectional threaded rod 131 to drive the bidirectional threaded rod 131 to rotate, so that the two clamping jaws 3 slide towards each other or away from each other on the sliding seat 1.

[0037] By arranging the two clamping jaws 3 on different threaded sections respectively. When the first driving member 16 drives the bidirectional threaded rod 131 to rotate, the two clamping jaws 3 will slide towards each other or away from each other on the sliding seat 1, which can realize the control of the distance between the clamping jaws 3, and then adapt to arresters of various different sizes, ensure the close fit between the detection device and the arrester, and improve the stability and accuracy of detection. The screw drive has a high transmission efficiency and can efficiently transmit the power of the first driving member 16 to the clamping jaws 3 to ensure the stable operation of the device.

[0038] Among them, the first threaded section and the second threaded section are two sections of the bidirectional threaded rod 131 arranged along the length direction.

[0039] Among them, the seat body 11 is a hollow shell structure, for example, it can be a hollow cuboid structure. The first driving member 16 can be arranged on the outer wall of the seat body 11 or inside the seat body 11.

[0040] Specifically, the length direction of the bidirectional threaded rod 131 is the same as the length direction of the seat body 11. The first driving member 16 drives the bidirectional threaded rod 131 to rotate, so that the two clamping jaws 3 will slide relative to each other or away from each other in the length direction of the bidirectional threaded rod 131 and the length direction of the seat body 11.

[0041] Among them, the first driving member 16 is connected to the bidirectional threaded rod 131 through a coupling.

[0042] Limit sliders 14 are threadedly connected to both the first threaded section and the second threaded section. A slide bar 132 is arranged inside the seat body 11. The slide bar 132 is arranged along the moving direction of the clamping jaws 3. Both of the two limit sliders 14 are slidably arranged on the slide bar 132. One of the clamping jaws 3 is connected to the limit slider 14 on the first threaded section, and the other clamping jaw 3 is connected to the limit slider 14 on the second threaded section.

[0043] By connecting the limit slider 14 to both the first thread segment and the second thread segment of the bidirectional threaded rod 131, and setting the limit slider 14 on the slide bar 132 along the moving direction of the clamping jaw 3, the clamping jaw 3 plays a good guiding role when moving on the seat body 11. The slide bar 132 provides support and guidance for the limit slider 14, ensuring that the clamping jaw 3 can move stably, effectively preventing the clamping jaw 3 from deflecting and shaking during the movement, thereby ensuring the stability and reliability of the detection device when adjusting the spacing between the clamping jaws 3.

[0044] There are two sliding rods 132 , and both sliding rods 132 are arranged parallel to the bidirectional threaded rod 131 .

[0045] The two sliding rods 132 are symmetrically arranged with respect to the bidirectional threaded rod 131 .

[0046] The limiting slider 14 is connected to the clamping jaw 3 in a one-to-one correspondence, so that the bidirectional threaded rod 131 drives the limiting slider 14 to move, and then drives the clamping jaw 3 to move at the same time.

[0047] The two limiting sliding blocks 14 are symmetrically arranged with respect to the central cross section of the bidirectional threaded rod 131 .

[0048] A guide ridge 15 is provided on the inner wall of the seat body 11 . The guide ridge 15 is provided along the moving direction of the clamping jaw 3 . Both the two limit sliders 14 are slidably provided on the guide ridge 15 .

[0049] By providing a guide rib 15 on the inner wall of the seat body 11, a guide function is provided for the limit slider 14. The limit slider 14 slides on the slide bar 132 and the guide rib 15 at the same time, forming a double guide structure, so that the movement trajectory of the clamping jaw 3 is more accurate during the sliding process toward or away from each other, further reducing the possibility of the clamping jaw 3 being offset during movement, and can more accurately adapt to arresters of different specifications, ensuring that the detection device is firmly fixed on the arrester.

[0050] The guiding ridges 15 are provided to enhance the overall structural rigidity of the sliding seat 1. They not only provide guidance for the limit slider 14, but also strengthen the internal support of the sliding seat 1 to a certain extent, so that the sliding seat 1 can better maintain its own shape and structural stability when it is subjected to the force generated by the movement of the clamping jaws 3 and the external force that may occur during the detection process.

[0051] There are two guide ribs 15 , and both guide ribs 15 are arranged parallel to the bidirectional threaded rod 131 .

[0052] The two guide ridges 15 are symmetrically arranged with respect to the bidirectional threaded rod 131 .

[0053] The guide ridge 15 may be integrally formed on the seat body 11 .

[0054] Specifically, a guiding rib 15 and a sliding rod 132 are arranged on one side of the bidirectional threaded rod 131, and another guiding rib 15 and another sliding rod 132 are arranged on the other side of the bidirectional threaded rod 131.

[0055] Specifically, among the guiding rib 15 and the sliding rod 132 on the same side of the bidirectional threaded rod 131, the guiding rib 15 is closer to the bidirectional threaded rod 131 than the sliding rod 132.

[0056] A screw fixing member 12 is arranged on the inner wall of the seat body 11. A through hole is arranged on the screw fixing member 12. The bidirectional threaded rod 131 passes through the through hole and is rotatably connected to the through hole through a bearing; the screw fixing member 12 is arranged between the first threaded section and the second threaded section.

[0057] By arranging a through hole on the screw fixing member 12 and enabling the bidirectional threaded rod 131 to pass through the through hole and be rotatably connected through a bearing, the friction force when the bidirectional threaded rod 131 rotates is reduced, making it smoother for the first driving member 16 to drive the bidirectional threaded rod 131 to rotate. At the same time, the screw fixing member 12 stably positions the bidirectional threaded rod 131 in the sliding seat 1, preventing axial displacement or radial wobbling during rotation. By arranging the screw fixing member 12 between the first threaded section and the second threaded section, that is, making the screw fixing member 12 roughly in the middle of the bidirectional threaded rod 131, it can play a central supporting role for the bidirectional threaded rod 131. When the first driving member 16 drives the bidirectional threaded rod 131 to rotate and further drives the clamping jaw 3 to move, the screw fixing member 12 can effectively balance the forces on both sides of the bidirectional threaded rod 131. Avoiding the eccentric force generated by the movement of the clamping jaw 3 from causing the bidirectional threaded rod 131 to bend or deform, ensuring the stable rotation of the bidirectional threaded rod 131.

[0058] Among them, the screw fixing member 12 can be integrally formed on the seat body 11.

[0059] Among them, the outer ring of the bearing is fixedly connected to the hole wall of the through hole, and the inner ring is fixedly sleeved on the outer wall of the bidirectional threaded rod 131.

[0060] Among them, the outer wall of the bidirectional threaded rod 131 where it is sleeved with the bearing is a smooth circumferential surface without threads. That is, one side of the screw fixing member 12 is the first threaded section, and the other side is the second threaded section.

[0061] The clamping jaw 3 includes a jaw housing 31 and a jaw slider 331. The jaw housing 31 is connected to the limit slider 14. The jaw housing 31 is arranged perpendicular to the base 11. The jaw slider 331 is slidably arranged on the jaw housing 31. The second driving member 32 is respectively connected to the jaw housing 31 and the jaw slider 331 to drive the jaw slider 331 to slide toward the outside of the jaw housing 31 in a direction away from the base 11, or to drive the jaw slider 331 to slide toward the inside of the jaw housing 31 in a direction close to the base 11. The jaw sliders 331 of the two jaws 3 are both provided with sensors 332, and the two sensors 332 are arranged opposite to each other. The lightning arrester detection device includes a detector, and the two sensors 332 are respectively connected to the detector.

[0062] By making the claw housing 31 slidably connected with the limit slider 14, and driving the clamping slider 331 to slide on the claw housing 31 through the second driving member 32, the detection device can flexibly adjust the position of the clamping slider 331 according to the shape and size of the lightning arrester, and then adjust the distance between the sensor 332 installed on the clamping slider 331 and the lightning arrester. By setting relative sensors 332 on the clamping sliders 331 of the two clamping jaws 3, and connecting the sensors 332 to the detector, the lightning arrester can be detected.

[0063] Among them, the claw housing 31 is connected to the limit slider 14. When the sliding seat 1 adjusts the spacing of the clamping jaws 3, the claw housing 31 moves accordingly. At the same time, the clamping jaw slider 331 can slide independently on the claw housing 31. This makes the detection device more flexible in adapting to different specifications of lightning arresters. It can not only adjust the spacing of the entire clamping jaws 3, but also fine-tune a single clamping jaw 3, which greatly improves the adaptability of the device to various complex shapes and sizes of lightning arresters and broadens the application range of the detection device.

[0064] The claw housing 31 is disposed perpendicular to the outer wall of the seat body 11 , and the sliding direction of the clamping jaw slider 331 on the claw housing 31 is toward or away from the outer wall of the seat body 11 where the claw housing 31 is located.

[0065] Specifically, the claw housing 31 is a hollow shell structure, and one end away from the seat body 11 is open to form an opening for the clamping claw slider 331 to slide out of or into the claw housing 31. The second driving member 32 can drive the clamping claw slider 331 to slide out of the claw housing 31 through the opening in a direction away from the seat body 11, thereby extending the overall length of the clamping claw 3. The second driving member 32 can drive the clamping claw slider 331 to slide out of the claw housing 31 through the opening in a direction close to the seat body 11, thereby shortening the overall length of the clamping claw 3. The clamping claw slider 331 does not separate from the claw housing 31 when sliding, that is, when the clamping claw slider 331 slides to the extreme position in the direction away from the seat body 11, a part of it is still in the claw housing 31.

[0066] On the inner wall of the claw housing 31, there are provided guiding ribs 342. The claw slider 331 is provided with a sliding groove 341. The guiding ribs 342 and the sliding groove 341 are arranged along the sliding direction of the claw slider 331 on the claw housing 31, and the sliding groove 341 is in sliding fit with the guiding ribs 342.

[0067] By providing the guiding ribs 342 and the sliding groove 341, it provides guidance for the sliding of the claw slider 331 on the claw housing 31. When the second driving member 32 drives the claw slider 331 to move, the guiding ribs 342 can prevent the claw slider 331 from shaking, shifting or jamming, ensuring that it can slide stably along the set straight line direction. This makes the claw 3 more stable when adjusting its position, so as to ensure that the sensor 332 installed on the claw slider 331 can accurately reach the predetermined detection position, laying a foundation for obtaining reliable detection data.

[0068] Among them, the guiding ribs 342 and the sliding groove 341 extend along the sliding direction of the claw slider 331 on the claw housing 31.

[0069] Among them, the number of the guiding ribs 342 is two, the number of the sliding grooves 341 is two, and the guiding ribs 342 and the sliding grooves 341 are arranged in one-to-one correspondence. The sliding grooves 341 are arranged on both sides of the claw slider 331.

[0070] The lightning arrester detection device includes a telescopic rod 2. The telescopic rod 2 includes a first rod body 21 and a second rod body 24 that are slidably sleeved. The sliding seat 1 is connected to the first rod body 21, or the sliding seat 1 is connected to the second rod body 24.

[0071] By providing the telescopic rod 2, its own length can be flexibly changed according to the installation position of the lightning arrester and the on-site environment. By setting the sliding seat 1 to be connected to the first rod body 21 or to the second rod body 24, the sliding seat 1 can be more easily adjusted to the target position through the telescopic movement of the telescopic rod 2.

[0072] Among them, the first rod body 21 and the second rod body 24 are slidably sleeved along the length direction, thereby forming the telescopic rod 2.

[0073] Among them, both the first rod body 21 and the second rod body 24 are straight rods.

[0074] The first rod body 21 is slidably sleeved outside the second rod body 24. A plurality of fixing holes are arranged on the first rod body 21 along the extending direction. An accommodating cavity is arranged inside the second rod body 24. An elastic piece 221, a guiding column 231 and a spring 232 are arranged in the accommodating cavity. The elastic piece 221 includes a first section and a second section arranged at an angle. One end of the guiding column 231 is slidably connected to the first section, and the other end is connected to the second section. The spring 232 is sleeved on the guiding column 231. The spring 232 abuts against the first section and the second section respectively to apply an elastic force away from each other to the first section and the second section. A clamping convex block 222 is arranged on the first section. The clamping convex block 222 penetrates through the second rod body 24 from the inside to the outside. The clamping convex block 222 is used to selectively clamp into one of the plurality of fixing holes.

[0075] By arranging a plurality of fixing holes on the first rod body 21, the elastic piece 221 inside the second rod body 24 makes the clamping convex block 222 selectively snap into different fixing holes under the action of the spring 232, so that the length of the telescopic rod 2 can be accurately adjusted and reliably locked according to the actual detection requirements.

[0076] When adjusting the length of the telescopic rod 2, only need to press the clamping convex block 222 to compress the spring 232, then the first rod body 21 and the second rod body 24 can slide relative to each other. After releasing, the clamping convex block 222 automatically snaps into the corresponding fixing hole to complete the locking. The operation is simple and no additional tools are required, which greatly saves the preparation time before detection and improves the detection work efficiency.

[0077] The combination of the spring 232 and the elastic piece 221 provides a stable locking force for the telescopic rod 2. The spring 232 continuously applies a force to the elastic piece 221, so that the clamping convex block 222 tightly clamps in the fixing hole. Even if the device is vibrated or pulled by an external force during the detection process, it can prevent the telescopic rod 2 from telescoping by itself, ensure the stable position of the detection device during the detection process, and improve the overall structural stability and reliability of the detection device.

[0078] In this embodiment, the sliding seat 1 is connected to the second rod body 24. Specifically, the sliding seat 1 is connected to the end of the second rod body 24 that extends out of the first rod body 21.

[0079] Wherein, a sliding hole is arranged on the first section. The guiding column 231 is arranged in the sliding hole and is slidably connected to the first section. The other end of the guiding column 231 is fixedly connected to the second section.

[0080] Wherein, the elastic piece 221 arranged in the accommodating cavity is in a compressed state. The inner wall of the accommodating cavity squeezes the first section and the second section towards each other to generate elastic potential energy.

[0081] Wherein, the top of the clamping convex block 222 is an arc surface, which can play a guiding role when disengaging from the fixing hole and is more likely to disengage from the fixing hole.

[0082] Specifically, when unlocking the first rod body 21 and the second rod body 24, press the clamping projection 222 into the interior of the second rod body 24, so that the clamping projection 222 moves into the second rod body 24 against the elastic forces of the elastic piece 221 and the spring 232. When the clamping projection 222 is compressed to be close to disengaging from the fixing hole, pull the second rod body 24 to cause relative displacement between the first rod body 21 and the second rod body 24, and the clamping projection 222 completely disengages from the fixing hole through the arc surface at the top of the clamping projection 222. When the first rod body 21 and the second rod body 24 are displaced relative to each other to the required length, make the clamping projection 222 enter the nearest fixing hole to complete the locking between the first rod body 21 and the second rod body 24.

[0083] Wherein, the clamping projection 222 and the elastic piece 221 are of an integral structure.

[0084] A rotary connection seat 26 is provided on the telescopic rod 2, a rotating shaft is provided on the rotary connection seat 26, and a rotary connection block 25 is provided on the sliding seat 1, and the rotary connection block 25 is rotatably connected to the rotating shaft.

[0085] By providing the rotary connection seat 26 and the rotary connection block 25, when detecting the lightning arrester, the operator can flexibly adjust the angle of the sliding seat 1 according to the shape, position and detection requirements of the lightning arrester.

[0086] Wherein, the rotating shaft serves as the rotation center shaft of the rotary connection block 25.

[0087] Wherein, the rotary connection seat 26 is generally in a U-shaped structure, the rotating shaft is arranged at the opening of the U-shaped structure and is respectively connected to both ends of the U-shaped structure. A connection hole is provided through the rotary connection block 25, and the rotary connection block 25 is rotatably connected to the rotating shaft through the connection hole.

[0088] Wherein, the rotary connection seat 26 abuts against the rotary connection block 25, and thus the rotary connection seat 26 and the rotary connection block 25 are fixed at the required angle through the frictional force between the contact surfaces.

[0089] Specifically, when it is necessary to adjust the angle of the sliding seat 1, the operator applies an external force to overcome the static frictional force between the rotary connection seat 26 and the rotary connection block 25, so that the rotary connection block 25 rotates around the rotating shaft. After the sliding seat 1 rotates to the required angle, remove the external force. At this time, the static frictional force comes into play again, and the static frictional force prevents the rotary connection block 25 from continuing to rotate on the rotating shaft, thereby fixing the sliding seat 1 at this angle.
