Description

Technical Field

[0001] This utility model relates to a rapid inspection device for overhead power lines, and pertains to the field of overhead power line detection technology. Background Technology

[0002] When overhead power lines suffer external damage such as broken strands or corrosion, maintenance workers cannot pinpoint the location of the damage. They need to use detection equipment to mark the damaged areas. Current detection equipment typically uses drones equipped with high-definition cameras to take aerial photographs of the overhead power lines, followed by manual or AI algorithm identification of surface defects. However, during aerial photography, the camera's accuracy in identifying minute surface damage (such as microcracks, minor corrosion, and rust) is limited, and image quality is significantly affected by lighting conditions, easily leading to missed detections. These undetected minute damages can gradually expand into large-area damage over time, creating safety hazards. Utility Model Content

[0003] The purpose of this invention is to design a rapid inspection device for overhead power lines that can improve detection accuracy.

[0004] This utility model includes an openable support and a visual recognition mechanism disposed within the support. The support includes a front support, a rear support, and a detection seat. The detection seat is disposed between the front and rear supports, with its front and rear ends rotatably connected to the front and rear supports, respectively. An internal gear is disposed at the end of the detection seat adjacent to the rear support. A reduction motor is disposed at the lower part of the rear support. A drive wheel is disposed at the portion of the shaft of the reduction motor extending into the internal gear of the detection seat, and the drive wheel meshes with the internal gear of the detection seat. A travel motor is disposed at the front end of the front support, and a drive wheel is disposed on the shaft of the travel motor.

[0005] Furthermore, the inner hole of the detection seat is stepped, with the diameter of the middle part being larger than that of the two ends; the visual recognition mechanism is located in the middle part of the inner hole of the detection seat, and the visual recognition mechanism includes a detection device, which is fixedly installed on the circumferential surface of the inner hole of the detection seat; a supplementary light is provided on the front side of the detection device, and the supplementary light is fixedly installed on the stepped surface of the inner hole of the detection seat.

[0013] by Figure 1 The vertical direction in this embodiment is defined as the direction in which the device moves forward, which is defined as the front of this embodiment, and vice versa.

[0014] As shown in the figure, this embodiment includes a support, which consists of a front support 1, a rear support 2, and a detection seat 3. The detection seat 3 is disposed between the front support 1 and the rear support 2, with its front and rear ends respectively disposed in the inner cavities of the front and rear supports and rotatably connected to them. In this embodiment, the front and rear ends of the detection seat 3 are provided with outwardly protruding annular structures, and corresponding grooves matching the annular protrusions are provided at corresponding positions in the inner cavities of the front and rear supports, which are rotatably connected to the detection seat 3 through an embedded structure. The front support 1, the rear support 2, and the detection seat 3 are all openable and closable structures. For example, the rear support 2 consists of upper and lower parts. A hinge 16 is provided on the outer circumferential surface of one side section, which rotatably connects the upper and lower parts, allowing them to open and close. A latch 17 is provided on the outer circumferential surface of the other side section, which can be bolted to connect the latch 17 of the upper and lower parts to fix the rear support 2. The opening and closing structures of the front support 1 and the detection seat 3 are the same as those of the rear support 2, and will not be described in detail here.

[0015] In this embodiment, the parts at both ends of the detection seat 3 that connect to the front and rear supports adopt a rounded corner transition structure, which can reduce the friction between the detection seat 3 and the front and rear supports.

[0016] An internal gear 4 is provided on the end face adjacent to the rear support 2 of the detection seat 3. A reduction motor 5 is fixedly installed on the lower part of the rear support 2. The shaft of the reduction motor 5 extends forward into the internal gear 4, and a drive wheel 6 is fixedly installed at the end of the shaft. The drive wheel 6 meshes with the internal gear 4. When in use, the reduction motor 5 is started, which can control the rotation of the detection seat 3.

[0017] A forward-extending platform is fixedly installed at the lower front end of the front support 1. A travel motor 7 is installed on the platform. The shaft of the travel motor 7 extends to the middle of the inner hole of the front support 1 and is fixedly connected to a drive wheel 8. When in use, the drive wheel 8 can contact the outer surface of the overhead conductor and drive the support to move along the overhead conductor.

[0018] Each of the front support 1 and the rear support 2 has a set of auxiliary wheels 9 installed in its inner hole. In this embodiment, there are four auxiliary wheels 9 arranged in a cross shape in the inner holes of the front support 1 and the rear support 2. The length of each auxiliary wheel 9 extending inward is the same. The base is fixedly installed on the inner wall of the front and rear supports, and the wheels can rotate freely. The auxiliary wheels 9 are flush with the drive wheel 8. When the drive wheel 8 moves the support, each auxiliary wheel 9 contacts the outer surface of the overhead conductor, providing support and assisting in the movement of the support. In this embodiment, the opening and closing section of the support is inclined and offset from the installation position of each auxiliary wheel 9.

[0019] The inner hole of the detection seat 3 is stepped, with the diameter of the middle part of the inner hole being larger than that of the front and rear ends, and its outer circumferential surface corresponding to the change in the inner hole. A visual recognition mechanism is provided in the middle part of the inner hole of the detection seat 3. The visual recognition mechanism includes a detection device 13, which is fixedly installed on the circumferential surface of the inner hole of the detection seat 3. In this embodiment, the detection device 13 is a camera that can rotate with the detection seat 3. A supplementary light 14 is provided on the front side of the detection device 13 and is fixedly installed on the stepped surface on the front side of the inner hole of the detection seat 3, which can provide a light source when the detection device 13 photographs overhead conductors. In this embodiment, the distance between the stepped surface of the inner hole of the detection seat 3 where the supplementary light 14 is installed and the detection device 13 is greater than the distance between the stepped surface of the rear inner hole of the detection seat 3 and the detection device 13. At the same time, the supplementary light 14 is tilted downward, which can avoid overexposure of the detection device 13 during the shooting process. The stepped surface on the rear side of the inner hole of the detection seat 3 is tilted backward, which reduces the obstruction of the shooting area of ​​the detection device 13. In use, an infrared thermal imager and a laser scanner can be added around the detection device 13. The infrared thermal imager can be used to detect whether there is internal damage to the wire that causes overheating, and the laser scanner can be used to detect whether the wire has been deformed.

[0020] A lifting cylinder 10 is provided on the rear side of the geared motor 5. The cylinder body of the lifting cylinder 10 is fixedly installed on the outer circumference of the rear support 2 by clamps and bolts. The upper end of the cylinder body and the piston rod extend upward into the inner hole of the rear support 2. An insulating brush 11 is fixedly installed on the upper end of the piston rod. When in use, the lifting cylinder 10 can control the insulating brush 11 to move upward. The insulating brush 11 marks the damaged part with the pre-dipped marking pigment, so that maintenance personnel can find the damaged part.

[0021] A first power supply 12 is provided at the lower end of the front support 1. The first power supply 12 is fixedly connected to the outer circumferential surface of the front support 1. It is electrically connected to the reduction motor 5, the travel motor 7, and the lifting cylinder 10 through a circuit to supply power to each device. A second power supply 15 is provided in the middle of the inner hole of the detection seat 3. The second power supply 15 is located between the detection device 13 and the supplementary light 14. It is fixedly installed on the circumferential surface of the inner hole of the detection seat 3 and can rotate with the detection seat 3. It is electrically connected to the detection device 13 and the supplementary light 14 through a circuit to ensure that the detection device 13 and the supplementary light 14 are powered during the rotation scanning process.

[0022] In this embodiment, the detection seat 3 is first fastened to the outer circumference of the conductor. Then, the front support 1 and the rear support 2 are fastened to the front and rear ends of the detection seat 3, respectively. During the fastening process, the drive wheel 6 is inserted into the internal gear 4 to mesh with it. After fastening, bolts are installed on the locking buckle 17 for fixation. After installation, the reduction motor 5 is started to make the detection seat 3 start to rotate. The travel motor 7 is started, and the support is moved forward along the overhead conductor through the drive wheel 8. During the movement, the detection device 13 scans the overhead conductor along the spiral path to identify the damaged parts. When a damaged part is identified, the reduction motor 5 and the travel motor 7 are stopped, and the lifting cylinder 10 is started. The lifting cylinder 10 pushes the insulating brush 11 upward, and the insulating brush 11 applies the pre-dipping coating to the surface of the conductor. After completion, the lifting cylinder 10 is reset, and the reduction motor 5 and the travel motor 7 are started to continue the detection. Subsequent maintenance personnel can find the damaged parts of the conductor according to the coating markings.
