[0002] A lightning arrester, also known as an overvoltage protector, is installed near the protected equipment and connected in parallel with the protected equipment when in use. Under normal circumstances, the lightning arrester is not conductive (only a leakage current of microamperes flows at most). When the voltage acting on the lightning arrester reaches the arrester's operating voltage, the lightning arrester is conductive, passing a large current, releasing the overvoltage energy and limiting the overvoltage to a certain level to protect the insulation of the equipment.

[0012] A method for using a multi-station switching lightning arrester high-efficiency detection device, the method comprising the following steps: Before testing the arrester, the staff will push the mounting plate into the mounting slot to force the mounting plate against the slot wall. At this time, the insert plate that is flush with the outer wall of the mounting plate will be aligned with the slot. Then the staff will use the hexagonal wrench to turn the hexagonal screw to enable the movable plate that matches the thread of the hexagonal screw to move along the hexagonal screw in the mounting plate. When the movable plate moves, the push slot will push the connecting block through the inclined slot wall. The plug-in plate is inserted into the slot through the mounting plate, thereby fixing the mounting plate and the fixing seat on the movable table, so that the staff can place the lightning arrester conveniently. The operation is simple, and the staff can remove and replace the fixing seat to adapt to lightning arresters of different sizes. Then, the fixing plate is pushed by starting the electric push rod, so that the fixing plate can move up and down to adapt to lightning arresters of different heights. Then, the drive motor is started to rotate the screw rod, so that the two matching blocks that match the screw rod thread move oppositely along the screw rod. Then the matching block drives the clamping plate to clamp and fix the lightning arrester to prevent the lightning arrester from moving and deflecting. Then the working motor is started to rotate the main synchronous wheel. The main synchronous wheel, the auxiliary synchronous wheel and the toothed synchronous belt cooperate to make the connecting plate drive the slide rail to move along the guide groove. As the connecting plate moves, the connecting rod will first slide in the first transverse groove and gradually slide into the inclined groove. At this time, the connecting rod will slide along the skewed inclined groove, thereby driving the movable platform and prompting the sliding block to slide along the slide rail. The fixing seat is moved away from the center of the test bench to avoid collision between the two fixing seats moving in opposite directions. At this time, the connecting rod will slide into the second transverse groove and gradually slide into the first transverse groove on the other side of the test bench, so that the lightning arrester after inspection is away from the control box and the lightning arrester that has not been inspected is moved under the contact. The contact is then pushed down by the electric telescopic rod to make the contact contact with the lightning arrester. The staff then connects the external circuit and contacts, or connects to the detection instrument to complete the inspection.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a working motor, a main synchronous wheel, a secondary synchronous wheel, a toothed synchronous belt, a connecting plate, a connecting rod, a first transverse groove, an oblique groove and a second transverse groove, and starts the working motor to rotate the main synchronous wheel, and utilizes the cooperation of the main synchronous wheel, the secondary synchronous wheel and the toothed synchronous belt to make the connecting plate drive the slide rail to move along the guide groove. At the same time, the connecting rod will first slide along the first transverse groove and gradually slide into the oblique groove. When the connecting rod slides into the oblique groove, it will drive the movable table to move, prompting the sliding block to slide along the slide rail, so that the fixed seat is away from the center position of the detection table, thereby avoiding collision when the two fixed seats moving in opposite directions approach each other. At this time, the connecting rod will slide into the second transverse groove and gradually slide into the first transverse groove on the other side of the detection table, so that the lightning arrester after detection is away from the control box, and the lightning arrester not detected is moved under the contact, completing the process switching of the lightning arrester detection, so that the installation and disassembly work can be completed during the detection, thereby improving the detection efficiency; 2. In the present invention, an electric push rod, a fixed plate, an open slot, a drive motor, a screw rod, a matching block and a clamping plate are provided. By starting the electric push rod to push the fixed plate, the fixed plate moves up and down to adapt to the height of the lightning arrester. Then, the drive motor is started to drive the screw rod to rotate, so that the two matching blocks that match the screw rod thread slide along the screw rod in the open slot. The threads at both ends of the screw rod have opposite directions, so that the two matching blocks can respectively drive the two clamping plates to move in opposite directions, so that the two clamping plates clamp and fix the lightning arrester to prevent the lightning arrester from moving and deviating. The movable fixed plate and clamping plate can adapt to lightning arresters of different sizes, thereby improving applicability. 3. In the present invention, by arranging a hexagonal screw, a movable plate, a push groove, a connecting block, an insert plate, a mounting groove and a slot, the mounting plate is completely pushed into the mounting groove to align the insert plate with the slot. Then the staff rotates the hexagonal screw with a hexagonal wrench, so that the movable plate matched with the hexagonal screw thread moves in the mounting plate. When the movable plate moves, the push groove pushes the connecting block, so that the insert plate passes through the mounting plate and is inserted into the slot, thereby fixing the mounting plate and the fixing seat on the movable table, so that the staff can place the lightning arrester conveniently. The operation is simple, and it is convenient for the staff to remove and replace the fixing seat to adapt to lightning arresters of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The technical solution of the present application will be further described in detail below in conjunction with specific implementation methods.

[0016] like Figure 1-6 As shown, the present invention provides a technical solution: a multi-station switching lightning arrester high-efficiency detection device, including a detection platform 1, a plurality of support legs 2 are connected below the detection platform 1, a control box 3 is fixedly installed on one side above the detection platform 1, and a first transverse groove 4, an oblique groove 5 and a second transverse groove 6 are continuously opened on the detection platform 1. The first transverse groove 4, the oblique groove 5 and the second transverse groove 6 are interconnected, and the first transverse groove 4, the oblique groove 5 and the second transverse groove 6 together constitute a trapezoidal structure, and the connecting rod 15 slides in the first transverse groove 4, the oblique groove 5 and the second transverse groove 6. The trapezoidal structure formed by the first transverse groove 4, the oblique groove 5 and the second transverse groove 6 enables the two movable platforms 14 to move in opposite directions along the guide groove 8, and can be driven by the connecting rod 15 to synchronously complete the work of moving away from each other, thereby avoiding collision.

[0017] A working motor 7 is fixedly installed under the testing table 1, and a guide groove 8 is opened on the testing table 1. A main synchronous wheel 9 is rotatably connected to one side of the testing table 1, and a secondary synchronous wheel 10 is rotatably connected to the other side of the testing table 1. A toothed synchronous belt 11 is installed on the main synchronous wheel 9 and the secondary synchronous wheel 10. Two connecting plates 12 are symmetrically connected to the toothed synchronous belt 11, and a slide rail 13 is connected to the connecting plate 12. The output shaft of the working motor 7 is connected to the main synchronous wheel 9. There are two guide grooves 8 and they correspond to the position of the toothed synchronous belt 11. The connecting plate 12 slides in the guide groove 8 and is guided and restricted by the guide groove 8, so that the connecting plate 12 can smoothly drive the slide rail 13 and the movable table 14 to move.

[0018] A movable platform 14 is slidably mounted on the slide rail 13. A mounting groove 33 is provided on the movable platform 14. Slots 34 are provided on the groove walls on both sides of the mounting groove 33. The mounting plate 17 slides in cooperation with the mounting groove 33. The plug-in plate 32 passes through the mounting plate 17 and is inserted into the slot 34. By inserting the plug-in plate 32 into the slot 34, the mounting plate 17 can be fixed in the mounting groove 33, thereby preventing the mounting plate 17 from accidentally sliding and falling.

[0019] A connecting rod 15 is connected to the bottom of the movable platform 14, and sliding blocks 16 are connected on both sides of the bottom of the movable platform 14, and the sliding blocks 16 are slidably connected to the slide rails 13. A mounting plate 17 is slidably installed on the movable platform 14, and a hexagonal screw 29 is rotatably connected to the mounting plate 17. A movable plate 30 is threadedly installed on the hexagonal screw 29. The movable plate 30 contacts the inner wall of the mounting plate 17 and has multiple push grooves 31 on both sides. The movable plate 30 is slidably connected to the insert plate 32 through the push groove 31. The contact between the movable plate 30 and the inner wall of the mounting plate 17 can prevent the movable plate 30 from rotating crookedly on the hexagonal screw 29, so that the movable plate 30 can move smoothly in the mounting plate 17.

[0020] An electric push rod 18 is fixedly installed on the movable table 14, and the movable end of the electric push rod 18 is connected to a fixed plate 19. An open slot 20 is opened on the fixed plate 19. A drive motor 21 is fixedly installed on one side of the fixed plate 19. The output shaft of the drive motor 21 is connected to a screw rod 22. Two matching blocks 23 are installed on the screw rod 22 in a threaded manner. The screw rod 22 is rotatably connected to the fixed plate 19 through a bearing and is located in the open slot 20. The matching blocks 23 are arranged at both ends of the screw rod 22, and the two ends of the screw rod 22 are provided with corresponding direction. The thread is reversed, and the mating block 23 slides in the open groove 20 and contacts the groove wall, and a corrugated folding tube 37 is connected between the two mating blocks 23. When the screw rod 22 rotates to drive the two mating blocks 23 to move toward each other, the mating block 23 can compress or stretch the corrugated folding tube 37, and when the corrugated folding tube 37 is unfolded, it can cover and shield the screw rod 22, thereby reducing the contact between the screw rod 22 and the outside world, and the open groove 20 can limit the mating block 23 to prevent the mating block 23 from rotating and deflecting.

[0021] The matching block 23 is connected to the splint 24, the plug plate 32 is connected to the connecting block 35, the push grooves 31 on both sides of the movable plate 30 are inclined and form a V-shaped structure as a whole, the connecting block 35 slides in the push groove 31, the splint 24 is connected to the rubber pad 36, and the rubber pad 36 is provided with anti-slip lines, the mounting plate 17 is connected to the fixing seat 25, the control box 3 is installed with a detection instrument 26 on one side, the control box 3 is fixed with an electric telescopic rod 27, the electric telescopic rod 27 A contact 28 is installed at the movable end. Through the inclined design of the push groove 31, the push groove 31 can push the plug plate 32 to move through the connecting block 35 when the movable plate 30 moves. When the hexagonal screw 29 is reversed to retract the plug plate 32, the connecting block 35 will move to the end of the push groove 31. At this time, one side of the plug plate 32 will be flush with the outer wall of the mounting plate 17, thereby preventing the plug plate 32 from sliding completely into the interior of the mounting plate 17, so that the two side walls of the mounting plate 17 can restrict the plug plate 32.

[0022] A method for using a multi-station switching lightning arrester high-efficiency detection device, the method comprising the following steps: Before testing the arrester, the staff pushes the mounting plate 17 into the mounting groove 33, causing the mounting plate 17 to abut against the groove wall of the mounting groove 33. At this time, the insert plate 32, which is flush with the outer wall of the mounting plate 17, is aligned with the slot 34. Then the staff uses the hexagonal wrench to screw the hexagonal screw 29, causing the hexagonal screw 29 to rotate, so that the movable plate 30, which is threadedly engaged with the hexagonal screw 29, can move along the hexagonal screw 29 in the mounting plate 17. When the movable plate 30 moves, the push groove 31 pushes the connecting block 35 through the inclined groove wall. The insert plate 32 is inserted through the mounting plate 17 into the slot 34, thereby fixing the mounting plate 17 and the fixing seat 25 on the movable platform 14, so that the staff can place the lightning arrester conveniently. The operation is simple, and the staff can remove and replace the fixing seat 25 to adapt to lightning arresters of different sizes. Then, the fixing plate 19 is pushed by starting the electric push rod 18, so that the fixing plate 19 can move up and down to adapt to lightning arresters of different heights. Then, the drive motor 21 is started to rotate the screw rod 22, so that the two matching blocks 23 that are threadedly engaged with the screw rod 22 move oppositely along the screw rod 22; Then the matching block 23 drives the clamping plate 24 to clamp and fix the lightning arrester to prevent the lightning arrester from moving and deflecting. Then the working motor 7 is started to rotate the main synchronous wheel 9. The main synchronous wheel 9, the auxiliary synchronous wheel 10 and the toothed synchronous belt 11 cooperate to make the connecting plate 12 drive the slide rail 13 to move along the guide groove 8. As the connecting plate 12 moves, the connecting rod 15 will first slide in the first transverse groove 4 and gradually slide into the inclined groove 5. At this time, the connecting rod 15 will slide along the skewed inclined groove 5, thereby driving the movable platform 14 and prompting the sliding block 16 to slide along the slide rail 13. The fixing seat 25 is moved away from the center position of the test platform 1, thereby avoiding collision between the two fixing seats 25 moving in opposite directions. At this time, the connecting rod 15 will slide into the second transverse groove 6 and gradually slide into the first transverse groove 4 on the other side of the test platform 1, so that the lightning arrester after inspection is away from the control box 3, and the lightning arrester that has not been inspected is moved below the contact 28. Then, the contact 28 is pushed down by the electric telescopic rod 27 to make the contact 28 contact with the lightning arrester. After that, the staff connects the external circuit to the contact 28, or connects it to the detection instrument 26 to complete the inspection.

At this time, the connecting rod (15) slides into the second transverse groove (6) and gradually slides into the first transverse groove (4) on the other side of the test bench (1), so that the lightning arrester after detection is away from the control box (3), and the lightning arrester that has not been detected is moved to the bottom of the contact (28). Then, the contact (28) is pushed down by the electric telescopic rod (27) so that the contact (28) contacts the lightning arrester. Then, the staff connects the external circuit to the contact (28), or connects it to the detection instrument (26) to complete the detection.
