Description

Technical Field

[0002] With the popularization of power systems, electric energy has become an indispensable part of people's daily lives. Cables, as a dielectric material, play a key role in transmitting electric energy in the operation of power systems. The quality of wires and cables directly affects whether electricity use is safe and stable. The quality of wires and cables currently available on the market is uneven, and cannot guarantee to meet the operation needs of power systems. At the same time, wires and cables have become indispensable products in the fields of national economy, construction, and life. Cables are stored in an environment of alternating high and low temperatures, and cable component materials will expand and contract, resulting in line loss and cracks. Aging of wires will reduce their insulation performance and may cause cracks on the surface of the wires. Low-quality photovoltaic component materials may have defects or unevenness, and are prone to line loss and cracks, and even broken strands. Broken strands will affect the line current carrying capacity, cause corona, and reduce the mechanical properties of the line. When the cable is damaged and not handled for a long time, the cable damage will expand, affecting the stability and reliability of the components inside the cable. In severe cases, it will even affect the safety of the power grid and cause damage to people around.

[0003] Existing cable detection methods are mostly manual detection, which is not only inefficient, but also unable to accurately detect cables, has high labor costs, and is prone to errors, which is not conducive to subsequent cable maintenance.

The upper part of the threaded rod 25 is fixedly connected to the rotating block 29. The outer peripheral surface of the rotating block 29 is provided with anti-slip grooves 210. The anti-slip grooves 210 increase the friction. The rotating block 29 and the anti-slip grooves 210 are used together to facilitate the staff to rotate the threaded rod 25 to control the vertical movement of the movable plate 26.

[0052] The movable plate 26 is arranged in the guide groove 23, and the movable plate 26 can move in the vertical direction along the guide groove 23. A driven roller 27 is arranged between the two movable plates 26. Both ends of the driven roller 27 are screwed to the movable plate 26.

[0056] In a specific embodiment, the cable is set in the limit groove 28 between the driven roller shaft 27 and the active roller shaft 22, and the motor 211 is started. The motor 211 drives the active roller shaft 22 to rotate, so that the cable moves backward under the rotation of the active roller shaft 22, and continuous detection is performed, thereby improving the detection efficiency.

[0057] like Figure 1 and Figure 2 As shown, the detection assembly 5 includes: a fixing frame 51, a second hydraulic cylinder 52, a mounting frame 53, a high-speed camera 54 and a fill light 55, wherein the fixing frame 51 is a front door type structure, the two ends of the bottom of the fixing frame 51 are arranged at the left and right ends of the upper outer surface of the workbench 1, and the center of the upper outer surface of the fixing frame 51 is provided with a second hydraulic cylinder 52, and the stroke end of the second hydraulic cylinder 52 passes through the upper outer wall of the fixing frame 51 and is fixedly connected to the mounting frame 53;

When the cable to be detected passes through the mounting frame 53, the outer surface of the cable can be photographed by the high-speed camera 54. The high-speed camera 54 is connected to the CNC panel 10 by signal.

[0059] At the same time, both ends of each inner periphery of the mounting frame 53 are provided with fill lights 55, which are located on both sides of the high-speed camera 54 and are used to illuminate the outer surface of the cable, thereby improving the clarity of the high-speed camera 54 and making it easier to find damage on the outer surface of the cable;

[0061] In a specific embodiment, when the detection component 5 detects the cable to be detected, the second hydraulic cylinder 52 is started, and the stroke end of the second hydraulic cylinder 52 pushes the mounting frame 53 to move in the vertical direction. The vertical movement of the mounting frame 53 facilitates the adjustment of the vertical height of the mounting frame 53 according to the orientation of the cable to be detected, so that the cable to be detected passes through the middle of the mounting frame 53, thereby improving versatility. The fill light 55 is started to illuminate the cable to ensure the clarity of the high-speed camera 54, so as to facilitate the discovery of cracks, broken strands and other damage on the outer surface of the cable.

[0065] The first hydraulic cylinder 8 is used to adjust the height of the pressure plate 73 so that the pressure plate 73 can squeeze the paint inside the tank 7 and spray the paint directly onto the damaged part of the cable.

[0066] The upper rear end of the workbench 1 is provided with connecting plates 14 on both sides below the support frame 6, and a plurality of equidistantly arranged supporting rollers 15 are provided between the two connecting plates 14. The supporting rollers 15 and the connecting plates 14 are rotatably connected.

[0080] Step 4.2: The first hydraulic cylinder 8 is started, and the stroke end of the first hydraulic cylinder 8 moves downward to push the pressure plate 73 to move downward inside the tank body 7;

[0081] Step 4.3: The volume of the first inner cavity 71 increases to form a pressure difference, and the first inner cavity 71 inhales gas from the liquid inlet pipe 17 to maintain pressure balance, ensuring that the pressure plate 73 will not move due to external force;

[0082] Step 4.4: At the same time, the volume of the second inner cavity 72 becomes smaller, so that the paint is discharged from the connecting pipe 13 at the bottom, and the paint in the connecting pipe 13 is sprayed out from the spray gun 12;

[0083] Step 4.5: The staff sprays the paint onto the damaged part of the outer surface of the cable through the spray gun 12 to mark it, so as to facilitate the subsequent targeted repair.

At the same time, a motor is arranged on the traction assembly to enable the cables to be continuously moved backward for continuous detection, saving labor costs.

[0086] At the same time, the present invention rotates the rotating block to move the threaded rod in the vertical direction, and the threaded rod pushes the movable plate to move vertically synchronously, thereby adjusting the distance between the driven roller and the active roller, so that the traction assembly and the feeding assembly can adjust the distance between the driven roller and the active roller according to cables of different sizes to pull and fix the cables, thereby improving versatility.

[0087] Moreover, the detection component of the present invention uses a high-speed camera to photograph the outer surface of the cable, and uploads the image to the CNC panel to automatically identify damage on the outer surface of the cable, thereby realizing automated detection and improving detection efficiency. In addition, the staff sprays the damaged part of the cable with a spray gun, making it easier for the staff to repair the cracks in the cable.
