[0031] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0032] In one embodiment, Figures 1-9 As shown, an aging test detection device for wires and cables includes a base 1, with first slide grooves 2 provided on both sides of the base 1. Two adjustment plates 3 are slidably installed inside the base 1 through the first slide grooves 2. A protection box 5 is fixedly installed on the top of the base 1, a battery box 9 is installed on one side of the protection box 5, and an integrated circuit board 10 is installed on the other side of the protection box 5. A camera 13 is fixedly installed on the bottom of the protection box 5, and guide wheels 14 are symmetrically mounted on the bottoms of the two adjustment plates 3 for rotation.

[0033] A moving mechanism 4 is installed on the top of the two adjustment plates 3, an adjustment mechanism 6 is installed on both sides of the protective box 5, a driving mechanism 7 is installed on one side of the battery box 9, a second slide groove 11 is opened at the bottom of the protective box 5, and a reciprocating mechanism 8 is installed inside the protective box 5 through the second slide groove 11.

[0034] In this embodiment, the device is placed in the bridge, and the positions of the two adjustment plates 3 are adjusted by the adjustment mechanism 6 so that the guide wheels 14 of the two adjustment plates 3 fit the inner walls on both sides of the bridge. The structure is simple and easy to adjust according to bridges of different widths, thereby improving practicality. The driving mechanism 7 then drives the moving mechanism 4 and the reciprocating mechanism 8 to work at the same time. The moving mechanism 4 works to move the device inside the bridge. With the guide wheel 14, the device can turn in the bridge and can detect the cables in the bridge from beginning to end. The reciprocating mechanism 8 drives the infrared temperature sensor 12 to move back and forth left and right, and can detect the cables at the corners of the bridge, thereby improving the detection accuracy. If the conductor temperature is continuously >70°C or the temperature difference with the environment is >15°C, it indicates that the insulation is deteriorating. The camera 13 detects the outer skin of the cable to determine whether its surface is aged or damaged.

[0035] In one embodiment, Figure 4 As shown, the driving mechanism 7 includes a double-headed motor 71, which is fixedly mounted on one side of the battery box 9. Splined telescopic transmission shafts 72 are installed at both ends of the double-headed motor 71, and the external key of one of the splined telescopic transmission shafts 72 is connected to a second gear 73. The double-headed motor 71 drives the splined telescopic transmission shafts 72 at both ends to rotate, and the splined telescopic transmission shaft 72 drives the second gear 73 to rotate, thereby driving the moving mechanism 4 and the reciprocating mechanism 8 to work at the same time, thereby reducing energy consumption.

[0036] In one embodiment, Figure 5 As shown, the reciprocating mechanism 8 includes a reciprocating member 81, which is slidably installed inside the protective box 5 through the second slide groove 11. Tooth grooves are equidistantly provided on both sides of the interior of the reciprocating member 81. The interior of the reciprocating member 81 is meshedly connected with a semicircular gear 82, and the semicircular gear 82 and the protective box 5 are rotatably installed. The top key of the semicircular gear 82 is connected with a third gear 83, and the third gear 83 is meshed with the second gear 73. Two connecting members 84 are symmetrically fixedly installed at the bottom of the reciprocating member 81. The bottom ends of the two connecting members 84 pass through the protective box 5 and are fixedly installed with an infrared temperature sensor 12, and the infrared temperature sensor 12 is located at the bottom of the protective box 5. The second gear 73 drives the third gear 83 to rotate, and the third gear 83 drives the semicircular gear 82 to rotate, so that the reciprocating member 81 moves back and forth along the length direction of the second slide groove 11, thereby driving the infrared temperature sensor 12 to move back and forth left and right, so that cables at corners can also be detected, reducing detection errors.

[0037] In one embodiment, Figure 6 and Figure 7As shown, the moving mechanism 4 includes two fixed plates 41, and the two fixed plates 41 are fixedly mounted on the top of the adjusting plate 3, one side of one of the fixed plates 41 is rotatably mounted with two first pulleys 42 connected by keys, and one side of the other fixed plate 41 is rotatably mounted with a first rotating rod 43, and a second rotating rod 44 is rotatably mounted inside the first rotating rod 43, and a driving wheel 45 is rotatably mounted on the bottom ends of the first rotating rod 43 and the second rotating rod 44, and a second pulley 46 is mounted on one end of the two driving wheels 45, and a transmission belt 47 is installed between the second pulley 46 and the first pulley 42, and two shock-absorbing assemblies are provided at the bottom of the adjusting plate 3, and the shock-absorbing assembly includes an arc-shaped member 48, and the arc-shaped member 48 is fixedly mounted on the bottom of the adjusting plate 3, and an arc-shaped groove 49 is opened on one side of the arc-shaped member 48, and a spring 410 is fixedly mounted inside the arc-shaped groove 49, One end of the spring 410 is fixedly installed with a slider 411, and the slider 411 is slidably installed inside the arc groove 49. The two sliders 411 are fixedly connected to the second rotating rod 44 and the first rotating rod 43 respectively. One end of the spline telescopic transmission shaft 72 passes through the protection box 5 and the fixed plate 41 and is key-connected with the first pulley 42. The rotation of the spline telescopic transmission shaft 72 drives the first pulley 42 to rotate, and the cooperation of the transmission belt 47 and the second pulley 46 makes the driving wheel 45 rotate, and the driving wheel 45 contacts the bottom inside the tripod, thereby driving the equipment to move stably inside the bridge. Through the setting of the guide wheel 14, it can continue to move at the turning point of the bridge. The spring 410 is always in a compressed state. When an impact occurs, the spring 410 compresses and buffers. After the impact is absorbed, the spring 410 resets and drives the slider 411 to reset, so that the first rotating rod 43 and the second rotating rod 44 are reset, thereby improving the stability of driving.

[0038] In one embodiment, Figure 8 As shown, the adjusting mechanism 6 includes a first gear 61, which is rotatably mounted on one side of the protective box 5. The outside of the first gear 61 is meshed with two racks 62, and the two racks 62 are fixedly mounted on the two adjusting plates 3 respectively. A driving motor 63 is fixedly mounted on one side wall of the inner side of the protective box 5, and the output end of the driving motor 63 is connected to the first gear 61. The equipment is placed in the bridge, and the driving motor 63 drives the first gear 61 to rotate. The rotation of the first gear 61 causes the two racks 62 to move to both ends. Through the cooperation of the first slide groove 2, the two adjusting plates 3 slide stably until the guide wheels 14 of the two adjusting plates 3 fit with the inner wall of the bridge.

[0039] The working principle of the present invention is: this device performs aging detection on the cables installed in the bridge, places the device in the bridge, and drives the first gear 61 to rotate through the driving motor 63. The rotation of the first gear 61 causes the two racks 62 to move to both ends. Through the cooperation of the first slide groove 2, the two adjustment plates 3 slide stably until the guide wheels 14 of the two adjustment plates 3 fit with the inner wall of the bridge. At this time, the camera 13 and the infrared temperature sensor 12 are located directly above the cable.

[0040] The double-headed motor 71 drives the spline telescopic transmission shaft 72 at both ends to rotate, and the rotation of the spline telescopic transmission shaft 72 drives the first pulley 42 to rotate. The cooperation of the transmission belt 47 and the second pulley 46 makes the drive wheel 45 rotate, and the drive wheel 45 contacts the bottom inside the tripod, thereby driving the equipment to move stably inside the bridge. Through the setting of the guide wheel 14, it can continue to move at the turning point of the bridge. At the same time, the second gear 73 drives the third gear 83 to rotate, and the third gear 83 drives the semicircular gear 82 to rotate, so that the reciprocating member 81 moves back and forth along the length direction of the second slide 11, and then drives the infrared temperature sensor 12 to move back and forth left and right, so that the cables at the corners can also be detected, reducing the detection error. If the conductor temperature is continuously >70℃ or the temperature difference with the environment is >15℃, it indicates that the insulation is deteriorated. The camera 13 detects the outer sheath of the cable to determine whether its surface is aged and damaged.
