Description

Technical Field

[0001] This invention belongs to the field of surge arrester testing technology, specifically relating to a strength testing device for a new material surge arrester. Background Technology

[0002] The function of a surge arrester is to preferentially discharge to ground when an overvoltage occurs, thereby protecting electrical equipment. According to different structures, surge arresters can be divided into tube-type surge arresters, valve-type surge arresters, zinc oxide surge arresters, etc. Surge arresters are important safety protection devices in power systems.

[0003] Patent publication number CN111175132B discloses a surge arrester testing device, which includes at least a base frame and a control unit, as well as a first hydraulic cylinder and a second hydraulic cylinder, a fixed frame, a traction frame, a force application frame, a first pressure sensor, a pair of second pressure sensors, and a support frame. The control unit is fixed to the side wall of the base frame, the fixed frame is movably connected to the base frame, the traction frame is fixed to the base frame, the first hydraulic cylinder is movably connected to the base frame, and the drive end of the first hydraulic cylinder is movably connected to the traction frame. The first pressure sensor is disposed inside the traction frame, and the support frame is fixed to the base frame perpendicular to the fixed frame. The second hydraulic cylinder is detachably connected to the support frame. This patent can simulate the use state of surge arresters and detect whether the surge arrester is qualified by simulating the stress conditions during use.

[0004] The aforementioned device also has the following problems: the device automatically adapts to and detects surge arresters of different lengths through a fixed frame, but during the testing process, if it is necessary to test the strength on the other side of the surge arrester, it needs to be removed and flipped over for adjustment. When placing it, the device needs to be repositioned and calibrated, which easily increases the complexity of the device adjustment and may reduce the accuracy of the test data; at the same time, the end face of the surge arrester is easily damaged by tilting due to the non-horizontal limiting of the device during the limiting process before testing; and before the testing mechanism tests, it is difficult to remove solid particles that may be attached to the surface of the surge arrester, which may easily reduce the testing accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a strength testing device for a new type of surge arrester, in order to solve the problem mentioned in the background art that the end face of the surge arrester is easily damaged by tilting due to the non-horizontal limiting of the device during the limiting process before testing.

[0006] To achieve the above objectives, the present invention provides a strength testing device for a new type of surge arrester, comprising: a base, several support rods symmetrically arranged on the top of the base, a top plate on the top of the support rods, an electric lead screw between the bottom of the top plate and the top of the base, two electric slide rails symmetrically arranged on the top of one end of the back of the base, a shaped plate slidably installed inside the electric slide rails, a drive mechanism fixedly installed on the side of the shaped plate near the electric lead screw, a bearing frame fixedly installed at the output end of the drive mechanism, several sliding rods equidistantly and slidably installed inside the bearing frame via springs, and an arc-shaped block fixedly installed at one end of each sliding rod inside the bearing frame. When the auxiliary equipment transports the surge arrester to be tested horizontally between the two bearing frames on opposite sides, the electric slide rails are activated, causing the shaped plate and drive mechanism to move horizontally, the drive mechanism to move the bearing frame synchronously, and the bearing frame to move the sliding rods and arc-shaped blocks synchronously. At this time, the arc surface of the arc-shaped block contacts and abuts the end face of the surge arrester, generating a displacement force that causes the sliding rods to move along... The surge arrester slides outward from the inside of the support frame, relying on the spring force to keep the arc-shaped block in close contact with the end face of the surge arrester, thus completing the centering and limiting of the surge arrester inside the support frame. The outer wall of the electric screw is penetrated and movably installed with a detection mechanism. Two L-shaped plates are symmetrically and fixedly installed on the back of the detection mechanism. The L-shaped plates are equipped with anti-deviation devices to detect whether the two ends of the surge arrester are horizontally limited. The anti-deviation devices are also equipped with anti-tilting devices to prevent the surge arrester from being subjected to non-vertical force due to dirt on its surface during testing. Then the electric screw rotates, and through the non-self-locking spiral groove on its outer wall, it guides the internal locking block of the detection mechanism, causing the detection mechanism to slide downward along the outer wall of the support rod. The bottom of the detection mechanism continuously applies stable pressure to the top of the surge arrester to complete the testing work. After the single-sided strength test is completed, the detection mechanism is reset by a certain distance by the electric screw and driven by the drive mechanism. The output end of the drive mechanism drives the support frame to rotate. At this time, the support frame automatically flips the surge arrester by relying on the sliding rod and the arc-shaped block. Then the detection mechanism moves down to continue testing.

[0007] In the above technical solution, further, a trapezoidal frame is slidably installed inside one end of the back of the base via a spring, and an arc-shaped plate is vertically slidably installed inside the base via a spring. Two elastic telescopic rods are symmetrically and fixedly installed on the top of the arc-shaped plate, and an abutment plate is fixedly installed on the top of the telescopic end of each elastic telescopic rod. When the detection mechanism drives the L-shaped plate to descend, the bottom of the L-shaped plate contacts and abuts the inclined surface of the trapezoidal frame, generating a horizontal force on the trapezoidal frame, which then slides horizontally along the inside of the base. At this time, the trapezoidal frame abuts the arc surface of the arc-shaped plate, and the arc-shaped plate drives the elastic telescopic rods to slide horizontally. The telescopic rod moves upward, and the elastic force at the telescopic end of the elastic telescopic rod is less than the elastic force between the curved plate and the base. The telescopic end of the elastic telescopic rod drives the contact plate to move synchronously. After the contact plate rises, it forms support for the bottom of the surge arrester. The detection mechanism moves upward, and the contact plate moves downward, so it will not contact the flipped surge arrester. The base has a hollow design, and a sliding groove is opened inside one end of the front of the base. The outer wall of the electric screw is a non-self-locking spiral groove. A sliding groove is opened on the back of the irregular plate. The output end of the drive mechanism moves through the interior of the irregular plate. The end face inside the bearing frame is used to place the surge arrester.

[0008] In the above technical solution, the arc-shaped block further causes the end face of the surge arrester to be in a limited state inside the bearing frame. The detection mechanism is slidably installed on the outer wall of the support rod. The inclined surface of the trapezoidal frame is located on the bottom movement trajectory of the L-shaped plate. The arc surface of the curved plate is located on the front movement trajectory of the trapezoidal frame. The contact plate supports the bottom of the surge arrester during detection. Both the contact plate and the curved plate are provided with air holes.

[0009] In the above technical solution, the anti-deviation device further includes a fixed plate, the side wall of which is fixedly installed between the L-shaped plates on their adjacent sides. An L-shaped protrusion plate is slidably installed on the top of one end of the back of the base via a spring. A vertical rod is slidably installed inside the groove of the irregular plate. When the L-shaped plate moves the fixed plate downward, the fixed plate abuts against the convex surface of the L-shaped protrusion plate. At this time, the L-shaped protrusion plate slides horizontally along the top of the base. Afterward, the L-shaped protrusion plate is reset by the spring force. Before this, when the irregular plate moves horizontally, it drives the vertical rod to move synchronously. The vertical rod drives the telescopic inclined plate to move synchronously. The telescopic inclined plate is limited by the vertical rod, causing it to move in an arc trajectory with the vertical rod as the axis. At the same time, its telescopic end begins to retract. The telescopic inclined plate is rotatably installed through a torsion spring on the outer wall of the vertical rod.

[0010] In the above technical solution, the convex surface of the L-shaped protrusion plate is located on the motion trajectory at the bottom edge of the fixed plate. The L-shaped protrusion plate has a built-in force sensor. The telescopic end of the telescopic inclined plate is hinged to the side wall surface of the L-shaped protrusion plate. Then, when the telescopic inclined plate is pushed by the L-shaped protrusion plate, it causes the telescopic inclined plate to drive the vertical rod to slide inside the groove of the irregular plate. If there is displacement between the electric slide rail and the irregular plate, the thrust data of the telescopic inclined plate on the vertical rod will change from the initial rated data. The force sensor built into the L-shaped protrusion plate provides timely information feedback.

[0011] In the above technical solution, a transmission rod is rotatably installed at one end of the back of the base. A non-self-locking spiral groove is opened on the outer wall of the top of the transmission rod. The transmission rod passes through and is movably installed inside the fixed plate. An elliptical block is fixedly installed through the outer wall of the transmission rod. When the fixed plate moves down, it guides the non-self-locking spiral groove on the outer wall of the transmission rod through its own built-in locking block, causing the transmission rod to start rotating. The transmission rod drives the elliptical block to revolve. An arc-head pressure plate is slidably installed on the back side wall of the base through a spring. The arc surface of the arc-head pressure plate contacts the outer wall of the elliptical block. The top of the trapezoidal frame is located on the bottom movement trajectory of the arc-head pressure plate. When the elliptical block revolves, it releases its contact with the arc-head pressure plate. The arc-head pressure plate slides horizontally along the back of the base by the spring force. When the elliptical block contacts it again, it pushes the arc-head pressure plate to reset. Thus, the arc-head pressure plate indirectly applies downward pressure to the top of the trapezoidal frame during the movement.

[0012] In the above technical solution, the anti-tilt device further includes a cylinder. The bottom of the cylinder is slidably installed inside the base by a spring. A rotating wheel is rotatably installed on the outer wall of the cylinder. A horizontal plate is fixedly installed through the outer wall of the top of the cylinder. When the elliptical block revolves, it abuts against the circumference of the rotating wheel, and the rotating wheel generates a force of motion. The rotating wheel causes the cylinder to slide horizontally along the inside of the base. Then the cylinder is reset by the spring force. This process is repeated, and the cylinder drives the horizontal plate to move synchronously. A fan is fixedly installed on the top of the horizontal plate. The horizontal plate drives the fan to reciprocate horizontally inside the base. The fan blows on the surface of the surge arrester through the air holes on the surface of the plate and the arc-shaped plate.

[0013] In the above technical solution, the circumferential surface of the rotor contacts the circumferential surface of the elliptical block, and the fan cleans the surface of the surge arrester by means of the air holes of the contact plate and the curved plate.

[0014] In the above technical solution, further, a contact frame is fixedly installed on the front of the horizontal plate, and the bottom of the contact frame is slidably installed on the bottom of the inner wall of the base. An inclined plate is vertically slidably installed inside the base groove by a spring. The top of the inclined plate slides through the top of the base, and the inclined surface of the inclined plate contacts the top of the contact frame. The horizontal plate drives the contact frame to slide horizontally back and forth along the bottom of the inner wall of the base. The contact frame abuts against the inclined surface of the inclined plate, causing it to generate a vertical movement force. A warning mechanism is provided inside the top of the inclined plate. The inclined plate moves upward along the base groove under the pushing action of the contact frame. The inclined plate drives the warning mechanism to move synchronously, that is, the warning mechanism can move back and forth up and down at the start of detection.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: through the cooperation of electric slide rail, irregular plate, drive mechanism, bearing frame, sliding rod, arc corner block, detection mechanism, L-shaped plate, trapezoidal frame, curved plate, elastic telescopic rod and contact plate, the drive mechanism, bearing frame and arc corner block adaptively complete the limiting and flipping work of surge arresters of different specifications, so that the surge arrester is always parallel to the top of the base for strength testing. At the same time, it simplifies the flipping test steps of the surge arrester, eliminating the need to remove and reposition, calibrate and place it, improving the testing efficiency and optimizing the accuracy of the test results. Through the cooperation of trapezoidal frame, curved plate and elastic telescopic rod, the contact plate can provide support for surge arresters of different thicknesses during testing, expanding the practicality of the equipment. At the same time, the contact plate will not come into contact with the surge arrester for friction, ensuring its smooth flipping and avoiding wear on the surface of the surge arrester.

[0016] By incorporating an anti-deviation device, which consists of an L-shaped plate, a fixed plate, an L-shaped protrusion plate, a vertical rod, a telescopic inclined plate, a transmission rod, an elliptical block, and an arc-shaped pressure plate, and utilizing the sliding motion of the L-shaped protrusion plate and the detection information from the force sensor, operators can readily detect whether the irregularly shaped plate has deviated from its course. This prevents damage to the arrester's end face when it is tilted due to the inner wall of the support frame, ensuring the arrester's integrity during testing. The downward pressure applied by the arc-shaped pressure plate ensures that the bottom of the trapezoidal frame remains firmly against the bottom of the base wall during horizontal sliding, preventing the trapezoidal frame from warping or becoming stuck. This prevents the two ends of the contact plate from tilting, ensuring consistent support strength between the contact plates and the arrester's bottom, which could interfere with the final test results, and also prevents the arrester's end face from detaching from the support frame.

[0017] By incorporating an anti-tilt device, and through the coordinated use of elliptical blocks, cylinders, wheels, horizontal plates, fans, contact frames, inclined panels, and warning mechanisms, the dynamic airflow of the fans effectively ensures that the entire surface of the surge arrester is clean before testing. This prevents solid particles from adhering to the surface and contacting the bottom of the testing mechanism, ensuring the testing mechanism can fully adhere to the arrester's testing surface and preventing test results from deviating from the actual strength. Furthermore, it avoids pitting caused by solid dirt obstructing the surface. The dynamic movement of the warning mechanism allows staff to monitor the operational status of the mechanical structure within the equipment, preventing malfunctions from interfering with the testing process and results. Simultaneously, before testing begins, it alerts nearby staff to stay away from the base to prevent injury from damage to the surge arrester. Attached Figure Description

Detailed Implementation

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-10 As shown, one embodiment of the present invention provides: a strength testing device for a new material surge arrester, comprising: a base 1, a plurality of support rods 2 symmetrically arranged on the top of the base 1, a top plate 3 arranged on the top of the support rods 2, an electric lead screw 4 arranged between the bottom of the top plate 3 and the top of the base 1, two electric slide rails 5 symmetrically arranged on the top of one end of the back of the base 1, a shaped plate 6 slidably installed inside the electric slide rail 5, a drive mechanism 7 fixedly installed on the side of the shaped plate 6 near the electric lead screw 4, a bearing frame 8 fixedly installed at the output end of the drive mechanism 7, a plurality of sliding rods 9 equidistantly and slidably installed inside the bearing frame 8 via springs, an arc-shaped block 10 fixedly installed at one end of the sliding rod 9 inside the bearing frame 8, and the electric lead screw 4 penetrating through the outer wall and movable. The device is equipped with a detection mechanism 11. Two L-shaped plates 12 are symmetrically and fixedly installed on the back of the detection mechanism 11. The L-shaped plates 12 are equipped with anti-deviation devices 17 to detect whether the two ends of the surge arrester are horizontally limited. The anti-deviation devices 17 are equipped with anti-tilt devices 18 to prevent the surge arrester from being subjected to non-vertical force due to dirt on its surface during the test. Through the drive mechanism 7, the bearing frame 8, and the arc corner block 10, the device adaptively completes the limiting and flipping work of surge arresters of different specifications, so that the surge arrester is always parallel to the top of the base 1 for strength testing. At the same time, it simplifies the flipping test of the surge arrester, eliminating the need to remove it and reposition it for recalibration and placement, thereby improving the testing efficiency and optimizing the accuracy of the test results.

[0022] A trapezoidal frame 13 is slidably installed inside the back end of the base 1 via a spring. An arc-shaped plate 14 is vertically slidably installed inside the base 1 via a spring. Two elastic telescopic rods 15 are symmetrically and fixedly installed on the top of the arc-shaped plate 14. A contact plate 16 is fixedly installed on the top of the telescopic end of the elastic telescopic rod 15. The base 1 has a hollow design, and a groove is opened inside the front end of the base 1. The outer wall of the electric screw 4 is a non-self-locking spiral groove. A groove is opened on the back of the irregular plate 6. The output end of the drive mechanism 7 moves through the interior of the irregular plate 6. The end face of the bearing frame 8 is used to place the surge arrester.

[0023] The arc-shaped block 10 causes the end face of the surge arrester to be in a limited state inside the bearing frame 8. The detection mechanism 11 is slidably installed on the outer wall of the support rod 2. The inclined surface of the trapezoidal frame 13 is located on the bottom movement trajectory of the L-shaped plate 12. The arc surface of the curved plate 14 is located on the front movement trajectory of the trapezoidal frame 13. The contact plate 16 supports the bottom of the surge arrester during detection. Both the contact plate 16 and the curved plate 14 are provided with air holes.

[0024] Through the cooperation of the trapezoidal frame 13, the curved plate 14 and the elastic telescopic rod 15, the contact plate 16 can provide support for surge arresters of different thicknesses during testing, expanding the practicality of the equipment. At the same time, the contact plate 16 will not come into contact with or rub against the surge arrester, ensuring its smooth rotation and preventing wear on the surface of the surge arrester.

[0025] In use, the auxiliary equipment horizontally transports the surge arrester to be tested between two support frames 8 on one side of each other. The electric slide rail 5 then activates, driving the shaped plate 6 and drive mechanism 7 to move horizontally. The drive mechanism 7 drives the support frames 8 to move synchronously, and the support frames 8 drive the sliding rod 9 and the arc-shaped block 10 to move synchronously. At this time, the arc surface of the arc-shaped block 10 contacts and abuts against the end face of the surge arrester, generating a displacement force that causes the sliding rod 9 to slide outward along the inside of the support frame 8. The spring force keeps the arc-shaped block 10 firmly against the end face of the surge arrester, thus completing the centering and limiting of the surge arrester inside the support frame 8. Afterward, the electric screw 4 rotates, guiding the built-in locking block of the detection mechanism 11 through its non-self-locking spiral groove on its outer wall. This causes the detection mechanism 11 to slide downward along the outer wall of the support rod 2, and the bottom of the detection mechanism 11 continuously applies stable pressure to the top of the surge arrester to complete the detection work. After the degree test is completed, the testing mechanism 11 resets to a certain distance by means of the electric lead screw 4 and is driven by the drive mechanism 7. The output end of the drive mechanism 7 drives the bearing frame 8 to rotate. At this time, the bearing frame 8 automatically flips the surge arrester by means of the sliding rod 9 and the arc corner block 10. Then the testing mechanism 11 moves down to continue testing. When the testing mechanism 11 drives the L-shaped plate 12 to descend, the bottom of the L-shaped plate 12 contacts and abuts the inclined surface of the trapezoidal frame 13. The trapezoidal frame 13 generates a horizontal force and slides horizontally along the inside of the base 1. At this time, the trapezoidal frame 13 abuts the arc surface of the arc plate 14. The arc plate 14 drives the elastic telescopic rod 15 to move upward. The elastic force at the telescopic end of the elastic telescopic rod 15 is less than the elastic force between the arc plate 14 and the base 1. The telescopic end of the elastic telescopic rod 15 drives the contact plate 16 to move synchronously. After the contact plate 16 rises, it forms support for the bottom of the surge arrester. The testing mechanism 11 moves up and the contact plate 16 moves down, so it will not contact the flipped surge arrester.

[0026] According to the above embodiments, the drive mechanism 7, the bearing frame 8, and the arc-shaped block 10 adaptively complete the limiting and flipping work of surge arresters of different specifications, ensuring that the surge arresters are always parallel to the top of the base 1 for strength testing. At the same time, it simplifies the flipping test steps of the surge arresters, eliminating the need to remove them and then reposition, calibrate, and place them, thus improving testing efficiency and optimizing the accuracy of the test results. Through the cooperation of the trapezoidal frame 13, the arc-shaped plate 14, and the elastic telescopic rod 15, the contact plate 16 can provide support for surge arresters of different thicknesses during testing, expanding the practicality of the equipment. At the same time, the contact plate 16 will not come into contact with or rub against the surge arresters, ensuring smooth flipping and preventing wear on the surface of the surge arresters.

[0027] like Figures 1-10 As shown, the second embodiment of the present invention provides: an anti-deviation device 17; The anti-deviation device 17 includes a fixed plate 171. The side wall of the fixed plate 171 is fixedly installed between the L-shaped plates 12 on their adjacent sides. An L-shaped protrusion plate 172 is slidably installed on the top of one end of the back of the base 1 via a spring. A vertical rod 173 is slidably installed inside the groove of the irregular plate 6. A telescopic inclined plate 174 is rotatably installed on the outer wall of the vertical rod 173 via a torsion spring.

[0028] The convex surface of the L-shaped protrusion plate 172 is located on the movement trajectory at the bottom edge of the fixed plate 171. The L-shaped protrusion plate 172 has a built-in force sensor, and the telescopic end of the telescopic inclined plate 174 is hinged to the side wall surface of the L-shaped protrusion plate 172.

[0029] A transmission rod 175 is rotatably mounted on one end of the back of the base 1. A non-self-locking spiral groove is opened on the outer wall of the top of the transmission rod 175. The transmission rod 175 passes through and is movably mounted inside the fixed plate 171. An elliptical block 176 is fixedly mounted through the outer wall of the transmission rod 175. An arc-head pressure plate 177 is slidably mounted on the back side wall of the base 1 via a spring. The arc surface of the arc-head pressure plate 177 contacts the outer wall of the elliptical block 176. The top of the trapezoidal frame 13 is located on the bottom movement trajectory of the arc-head pressure plate 177.

[0030] The sliding and pushing action of the L-shaped protrusion plate 172, along with the detection information from the force sensor, allows staff to be aware of whether the irregular plate 6 has deviated from its course at all times. This prevents the inner wall of the support frame 8 from causing damage to the surge arrester end face in a horizontally tilted state, ensuring the surge arrester remains undamaged during testing. The downward pressure applied by the arc-head pressure plate 177 ensures that the bottom of the trapezoidal frame 13 remains firmly attached to the bottom of the inner wall of the base 1, preventing the trapezoidal frame 13 from warping and causing the two ends of the contact plate 16 to tilt. This prevents the contact plate 16 from providing uneven support to the bottom of the surge arrester, thus avoiding interference with the final test results and preventing the surge arrester end face from falling off inside the support frame 8.

[0031] In use, when the L-shaped plate 12 moves the fixed plate 171 downward, the fixed plate 171 abuts against the convex surface of the L-shaped protrusion plate 172. At this time, the L-shaped protrusion plate 172 slides horizontally along the top of the base 1. Afterward, the L-shaped protrusion plate 172 is reset by the spring force. Before this, when the irregular plate 6 moves horizontally, it drives the vertical rod 173 to move synchronously. The vertical rod 173 drives the telescopic inclined plate 174 to move synchronously. The telescopic inclined plate 174 is limited by the vertical rod 173, causing it to move in an arc trajectory with the vertical rod 173 as the axis. At the same time, its telescopic end begins to retract. Then, when the telescopic inclined plate 174 is pushed by the L-shaped protrusion plate 172, it causes the telescopic inclined plate 174 to drive the vertical rod 173 to slide inside the groove of the irregular plate 6. If the electric slide rail 5 and the irregular plate 6 If displacement occurs, the thrust data of the telescopic inclined plate 174 on the vertical rod 173 will change from the initial rated data. The force sensor built into the L-shaped protrusion plate 172 provides timely feedback. When the fixed plate 171 moves down, it guides the non-self-locking spiral groove on the outer wall of the transmission rod 175 through its built-in locking block, causing the transmission rod 175 to start rotating. The transmission rod 175 drives the elliptical block 176 to revolve. When the elliptical block 176 revolve, it releases its contact with the arc head pressure plate 177. The arc head pressure plate 177 slides horizontally along the back of the base 1 by the spring force. When the elliptical block 176 contacts it again, it will push the arc head pressure plate 177 to reset. Thus, the arc head pressure plate 177 indirectly applies downward pressure to the top of the trapezoidal frame 13 during the movement.

[0032] According to the above embodiments, the sliding and pushing of the L-shaped protrusion plate 172, along with the detection information from the force sensor, allows the staff to know at all times whether the irregular plate 6 has deviated from its course, preventing the inner wall of the support frame 8 from causing skewing damage to the arrester end face in a horizontally inclined state, thus ensuring the arrester's non-destructive nature during the testing process. The downward pressure applied by the arc head pressure plate 177 causes the bottom of the trapezoidal frame 13 to always slide horizontally against the bottom of the inner wall of the base 1, preventing the trapezoidal frame 13 from warping and limiting its position, thereby causing the two ends of the contact plate 16 to tilt in one step. This prevents the contact plate 16 from providing uneven support strength to the bottom of the arrester, thus avoiding interference with the final test results, and also prevents the arrester end face from falling off inside the support frame 8.

[0033] like Figures 1-10 As shown, the third embodiment of the present invention provides: an anti-tilt device 18; The anti-tilt device 18 includes a cylinder 181. The bottom of the cylinder 181 is slidably mounted inside the base 1 by a spring. A rotating wheel 182 is rotatably mounted on the outer wall of the cylinder 181. A horizontal plate 183 is fixedly mounted through the outer wall of the top of the cylinder 181. A fan 184 is fixedly mounted on the top of the horizontal plate 183.

[0034] The circumferential surface of the rotor 182 contacts the circumferential surface of the elliptical block 176, and the fan 184 cleans the surface of the surge arrester by means of the air holes of the contact plate 16 and the curved plate 14.

[0035] A contact frame 185 is fixedly installed on the front of the flat plate 183. The bottom of the contact frame 185 is slidably installed on the bottom of the inner wall of the base 1. A slanted panel 186 is vertically slidably installed inside the sliding groove of the base 1 by a spring. The top of the slanted panel 186 slides through the top of the base 1. The slanted surface of the slanted panel 186 contacts the top of the contact frame 185. A warning mechanism 187 is provided inside the top of the slanted panel 186.

[0036] The dynamic airflow of the fan 184 effectively ensures that the entire surface of the surge arrester is clean before testing, preventing solid particles adhering to its surface from contacting the bottom of the testing mechanism 11. This avoids the testing mechanism 11 being unable to fully fit the testing surface of the surge arrester, preventing the test results from deviating from the actual strength, and further preventing pits from forming on its surface due to solid dirt obstruction. The dynamic movement of the warning mechanism 187 allows staff to know whether the mechanical structure in the equipment is operating normally, preventing the testing process and results from being interfered with due to malfunctions and lack of maintenance. At the same time, before the test begins, it reminds nearby staff to stay away from the base 1 to avoid injury to staff due to damage to the surge arrester.

[0037] In use, when the elliptical block 176 revolves, it abuts against the circumference of the rotating wheel 182, generating a force that causes the cylinder 181 to slide horizontally along the inside of the base 1. Afterward, the cylinder 181 returns to its original position due to spring force, and this process repeats. The cylinder 181 also drives the horizontal plate 183 to move synchronously, and the horizontal plate 183 drives the fan 184 to move horizontally back and forth inside the base 1. The fan 184 blows air onto the surface of the surge arrester through the air holes on the surface of the contact plate 16 and the curved plate 14. The horizontal plate 183 drives the contact frame 185 to slide horizontally back and forth along the bottom of the inner wall of the base 1. The contact frame 185 abuts against the inclined surface of the inclined panel 186, causing it to generate a force that causes vertical movement. Under the push of the contact frame 185, the inclined panel 186 moves upward along the slide groove of the base 1. The inclined panel 186 drives the warning mechanism 187 to move synchronously, that is, the warning mechanism 187 can move up and down back and forth at the start of detection.

[0038] According to the above embodiments, the dynamic airflow of the fan 184 effectively ensures that the entire surface of the surge arrester is clean before testing, preventing solid particles adhering to its surface from contacting the bottom of the testing mechanism 11, avoiding the testing mechanism 11 from being unable to fully fit the testing surface of the surge arrester, preventing the test results from deviating from the actual strength, and further preventing pits from being formed on its surface due to solid dirt obstruction; the dynamic movement of the warning mechanism 187 makes it easy for staff to know whether the mechanical structure in the equipment is operating normally, preventing the failure to maintain due to faults from interfering with the testing process and results, and at the same time, before the test begins, it reminds the surrounding staff to stay away from the base 1 to avoid injury to the staff due to damage to the surge arrester.
