[0001] This utility model relates to the field of high-voltage power line maintenance technology, specifically to a flaw detection device for tension clamps. Background Technology

[0002] In industrial production, X-ray inspection technology has become an important non-destructive testing technique, widely used in quality inspection, safety inspection, and product development across various industries.

[0003] The existing patent (publication number: CN220170910U) discloses a flaw detection device for a tension clamp, which adjusts the up and down tilt angle of the X-ray flaw detector transmitter by using a servo motor. The adjustment is convenient and precise, and it can be remotely controlled.

[0004] However, the above technical solution still has certain defects. The device needs to fly above the high-voltage conductor and hang on the conductor for flaw detection. If the position of the drone is not accurate when the operator controls the drone to hang it on the guide, the device will be unable to detect the fault. This will require repeated hovering, which greatly reduces the efficiency of the wire clamp detection. Therefore, a flaw detection device for tension wire clamps is proposed. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a flaw detection device for tension clamps, so as to solve the technical problem mentioned in the background that requires repeated hovering of UAVs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flaw detection device for tension clamps, comprising a drone, wherein the bottom end of the drone is provided with an adjustment component, and the bottom end of the adjustment component is provided with a moving component;

[0007] The adjustment assembly includes a support plate fixed to the bottom of the drone. Telescopic plates are slidably connected to both sides inside the support plate. A helical spring is fixed between the two sets of telescopic plates, and a U-shaped support frame is fixed to the end of the telescopic plate away from the helical spring. An inclined plate is fixed to the bottom end of the U-shaped support frame. The moving assembly includes a second servo motor installed on one side of the two sets of U-shaped support frames. A first pulley is fixed to the output end of the second servo motor. A belt is rotatably connected to the surface of the first pulley. A second pulley is rotatably connected to the inner wall of the belt away from the first pulley. A driven roller that changes the extension direction is provided on the surface of the belt. A moving shaft is fixed to the end of the first pulley and the second pulley away from the second servo motor. A circular groove is opened inside the moving shaft. A limiting spring is provided inside the circular groove. A circular block is connected to one end of the limiting spring. A circular shaft is fixed to the end of the circular block away from the limiting spring.

[0008] As a preferred technical solution, a digital imaging plate is installed on one side of the telescopic plate, a first servo motor is installed at the bottom of the support plate, a rotating rod is fixed at the output end of the first servo motor, and a flaw detector is provided at the end of the rotating rod away from the first servo motor.

[0009] As a preferred technical solution, the bottom end of the inclined plate and the connection end of the U-shaped support plate are both provided with arc surfaces.

[0010] As a preferred technical solution, the movable shaft is attached to the inner wall of the U-shaped support plate, and the bottom end of the movable shaft abuts against a wire.

[0011] As a preferred technical solution, the width of the moving shaft is smaller than the circumference diameter of the conductor, and the circular block is slidably connected to the circular groove.

[0012] As a preferred technical solution, the surface of the movable shaft is provided with several sets of long grooves.

[0013] In summary, the present invention has the following main advantages:

[0014] 1. This utility model uses two sets of moving shafts to rotate in contact with the wire, thereby driving the device to move along the wire until it reaches the desired position for flaw detection. This effectively reduces the repeated hovering caused by inaccurate drone placement, thus improving work efficiency. At the same time, placing the wire between the U-shaped support plate and the round shaft further improves the stability of the device during movement.

[0015] 2. This utility model uses the reaction force of the helical spring to cause the U-shaped support plates on both sides to contract inward and exert a certain squeezing force on both sides of the wire, which can make the drone stable on the wire. At the same time, the U-shaped support plates on both sides can quickly adapt to wires with different spacing, effectively reducing the time of repeated manual adjustments and improving work efficiency. When the drone drives the moving axis to connect to the wire. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A flaw detection device for tension clamps, such as Figure 1-5 As shown, it includes a drone 100, an adjustment component 200 at the bottom of the drone 100, and a moving component 300 at the bottom of the adjustment component 200.

[0027] Adjustment component 200 includes a support plate 210 fixed to the bottom of UAV 100. Telescopic plates 220 are slidably connected to both sides of the support plate 210. A helical spring 230 is fixed between the two sets of telescopic plates 220. A U-shaped support frame 240 is fixed to the end of the telescopic plate 220 away from the helical spring 230. An inclined plate 250 is fixed to the bottom of the U-shaped support frame 240. Movement component 300 includes a second servo motor 310 mounted on one side of the two sets of U-shaped support frames 240. A first pulley 320 is fixed to the output end of the second servo motor 310. The first pulley 320... A belt 330 is rotatably connected to the surface. A second belt 350 is rotatably connected to the end of the inner wall of the belt 330 away from the first belt pulley 320. The surface of the belt 330 is provided with a driven roller 340 to change its extension direction. A moving shaft 360 is fixed to the end of the first belt pulley 320 and the second belt pulley 350 away from the second servo motor 310. A circular groove 361 is opened inside the moving shaft 360. A limiting spring 370 is provided inside the circular groove 361. A circular block 380 is connected to one end of the limiting spring 370. A circular shaft 390 is fixed to the end of the circular block 380 away from the limiting spring 370.

[0028] The operator controls the drone 100 to take off, suspending it directly above the guide wire 150. The drone 100 is then slowly lowered, causing the ramps 250 to descend simultaneously. The curved surfaces of the ramps 250 contact the guide wire 150. The continued descent of the drone 100 forces the ramps 250 to move the U-shaped support plate 210 and the telescopic plate 220 to the sides, causing the guide wire 150 to slide inside the U-shaped support plate 210 until it contacts the moving shaft 360. The movement of the telescopic plate 220 stretches the helical spring 230. The reaction force of the helical spring 230 causes the U-shaped support plates 210 to contract inwards, exerting a certain compressive force on both sides of the guide wire 150. This provides stability for the drone 100 on the guide wire 150. Simultaneously, the U-shaped support plates 210 can quickly adapt to different spacings of the guide wire 150. This effectively reduces the time spent on repeated manual adjustments and improves work efficiency. When the drone 100 moves the moving shaft 360 onto the wire 150, the wire 150 will compress the round shaft 390, causing the round shaft 390 to stretch the limiting spring 370 and move to fit tightly against the wire 150. The second servo motor 310 is then started to drive the first pulley 320 to rotate, which in turn drives the second pulley 350 to rotate via the belt 330. This causes the two sets of moving shafts 360 to rotate against the wire 150, thereby moving the device along the wire 150 until it reaches the desired position for flaw detection. This effectively reduces the repeated hovering caused by inaccurate positioning of the drone 100, thus improving work efficiency. At the same time, placing the wire 150 between the U-shaped support plate 210 and the round shaft 390 further improves the stability of the device during movement.

[0029] Please refer to this carefully. Figure 1 and Figure 2 A digital imaging plate 110 is installed on one side of the telescopic plate 220, a first servo motor 120 is installed at the bottom of the support plate 210, a rotating rod 130 is fixed at the output end of the first servo motor 120, and a flaw detector 140 is provided at the end of the rotating rod 130 away from the first servo motor 120.

[0030] By starting the first servo motor 120, the rotating rod 130 is driven to rotate, which in turn drives the flaw detector 140 to rotate synchronously, making it easier for the flaw detector 140 to inspect the condition inside the wire clamp.

[0031] Please refer to this carefully. Figure 2 and Figure 3 The bottom end of the inclined plate 250 and the connection end of the U-shaped support plate 210 are both provided with arc surfaces. The moving shaft 360 is attached to the inner wall of the U-shaped support plate 210, and the bottom end of the moving shaft 360 abuts against the wire 150.

[0032] By setting an arc surface at the connection end between the bottom side of the inclined plate 250 and the U-shaped support plate 210, the wire 150 can be placed more conveniently inside the U-shaped support plate 210.

[0033] Please refer to this carefully. Figure 4 and Figure 5 The width of the movable shaft 360 is less than the circumference diameter of the wire 150. The circular block 380 is slidably connected to the circular groove 361. Several sets of long grooves 362 are opened on the surface of the movable shaft 360.

[0034] Making the width of the movable shaft 360 smaller than the circumference diameter of the wire 150 allows the sidewall of the shaft 390 to abut against the wire 150.

[0035] In use, by controlling the drone 100 to take off, the drone 100 is suspended directly above the guide wire 150. The arc surfaces of the two inclined plates 250 abut against the guide wire 150, causing the U-shaped support plate 210 and the telescopic plate 220 to move to both sides. This allows the guide wire 150 to slide to the inside of the U-shaped support plate 210. Under the reaction force of the helical spring 230, the U-shaped support plates 210 on both sides will retract inward and exert a certain squeezing force on both sides of the guide wire 150, which can stabilize the drone 100 on the guide wire 150. At the same time, the U-shaped support plates 210 on both sides can quickly adapt to different spacings of the guide wire 150, effectively reducing the impact of the U-shaped support plate 210 on the guide wire 150. The time spent on manual adjustments is reduced, improving work efficiency. When the drone 100 moves the movable axis 360 onto the guide wire 150, the two sets of movable axes 360 rotate in contact with the guide wire 150, thereby moving the device along the guide wire 150 until it reaches the desired position for flaw detection. This effectively reduces the repeated hovering caused by inaccurate positioning of the drone 100, thus improving work efficiency. At the same time, placing the guide wire 150 between the U-shaped support plate 210 and the round shaft 390 further improves the stability of the device during movement. All parts of the device not involved are the same as or can be implemented using existing technologies.
