Description

Technical Field

[0001] This invention relates to the field of power transmission line inspection technology, and in particular to a high-voltage power transmission line inspection device. Background Technology

[0002] With the increasing demand for electricity and the aging of power grid facilities, improving inspection efficiency and safety while reducing the risks associated with manual operations is crucial. As smart grids develop, real-time data monitoring and fault early warning are becoming increasingly important, and inspection robots can provide timely and accurate data support.

[0003] High-voltage line inspection robots mainly involve robot design, sensor technology, communication technology, and navigation and positioning. The inspection robot can move on high-voltage lines and identify and detect them through sensors and cameras installed on the robot. The identification and detection information is transmitted to ground personnel through wireless communication technology. Ground personnel control the inspection robot to carry out inspection operations wirelessly.

[0004] However, current high-voltage lines are typically multiple lines running side-by-side. Inspection robots can usually only identify and inspect a single line. After identifying and inspecting a single line, the robot needs to be moved to other high-voltage lines that haven't been identified or inspected. There are currently two adjustment methods. One is for workers to climb onto the towers at both ends of the high-voltage line. When inspecting the other end, the workers on that side adjust the robot's position to move it to another high-voltage line. The drawback of this method is that workers need to climb the towers at both ends of the high-voltage line, increasing the operational risk for workers and increasing labor costs. The other method is for the robot to return along the same route when inspecting the other end of the high-voltage line, and then the workers on that side adjust the robot's position. Because high-voltage lines are long, this method, while saving labor costs, significantly increases the robot's energy consumption, reduces the inspection device's battery life, and also reduces inspection efficiency.

[0005] Therefore, this invention proposes a high-voltage transmission line inspection device. Summary of the Invention

Detailed Implementation

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, referring to Figures 1 to 3 This is the first embodiment of the present invention. This embodiment provides a high-voltage transmission line inspection device, including a body 1, on which a connecting plate 11 is provided; the connecting plate 11 and the body 1 are fixedly connected, and the body 1 is located in the middle of the connecting plate 11.

[0032] The first rotating component 2 is provided in two sets, and the two sets of the first rotating component 2 are respectively located at both ends of the connecting plate 11; the second rotating component 3 is located on the first rotating component 2, and the rotation axis of the first rotating component 2 and the rotation axis of the second rotating component 3 are perpendicular to each other; the support frame 4 is located at the rotating end of the second rotating component 3; since the rotation axes of the first rotating component 2 and the second rotating component 3 are perpendicular to each other, the support frame 4 can be moved in any direction to change the relative position of the support frame 4 and the connecting plate 11.

[0033] The sliding frame 5 is slidably connected to the support frame 4; the telescopic component 6 is used to control the sliding trajectory of the sliding frame 5 on the support frame 4.

[0034] The drive wheel 7 is mounted on the support frame 4; the drive wheel 7 can rotate on its own; the driven wheel 8 is mounted on the sliding frame 5; when the sliding frame 5 slides, the driven wheel 8 will move together with the sliding frame 5.

[0035] The sliding frame 5 is provided with a baffle 51. When the telescopic member 6 extends or retracts, it can change the distance between the driven wheel 8 and the baffle 51 and the drive wheel 7 respectively. The end of the sliding frame 5 away from the telescopic member 6 is provided with a baffle 51, and the baffle 51 and the sliding frame 5 are arranged perpendicularly.

[0036] It should be noted that the first rotating component 2 and the second rotating component 3 can be rotational drive structures such as drive motors or motors, and the telescopic component 6 can be an electric push rod.

[0037] Specifically, the baffle 51 is provided with a limit buckle 52, which is located at the end of the baffle 51 away from the sliding frame 5.

[0038] The support frame 4 has a connecting end 41 at the end away from the sliding frame 5. The connecting end 41 and the support frame 4 are arranged perpendicularly. The connecting end 41 is fixedly connected to the rotating end of the second rotating member 3.

[0039] In use, the first rotating component 2, the second rotating component 3, the telescopic component 6, and the drive wheel 7 are controlled by remote control in order to control the operating status and form of the equipment.

[0040] High-voltage frames are typically constructed from angle steel, and high-voltage lines are installed on these frames, as shown in the reference section. Figure 7 The operator places both baffles 51 on the surface of the angle steel, and then uses the limit buckle 52 to limit the connection between the baffles 51 and the angle steel, which can prevent the baffles 51 and the angle steel from separating.

[0041] When the equipment climbs on the angle steel, the support frame 4 can be moved by the first rotating part 2 and the second rotating part 3 on both sides, so that the baffles 51 on both sides can move to different angle steel positions to change the posture and position of the equipment. The climbing pattern can be referred to Figure 6When climbing from the angle iron onto the high-voltage line, the connection to the high-voltage line is achieved by placing the high-voltage line between the drive wheel 7 and the driven wheel 8, allowing the drive wheel 7 to rest on the high-voltage line. Then, the sliding frame 5 is controlled to slide via the telescopic member 6, bringing the driven wheel 8 closer to the drive wheel 7. The high-voltage line is clamped between the driven wheel 8 and the drive wheel 7. The high-voltage line then serves as the load-bearing component for the device's weight. The sliding frame 5, still on the angle iron, is moved by controlling the movement of the telescopic member 6. First, the sliding frame 5 is raised, and then, in conjunction with the rotation of the first rotating member 2 and the second rotating member 3, the drive wheel 7 on that side also rests on the high-voltage line. The state of the device on the high-voltage line can be seen from [the following text is incomplete and requires further context]. Figure 1 In summary, this equipment can climb on angle steel and reach high-voltage lines. This means that workers do not need to be particularly close to the high-voltage lines to work. They only need to hang the equipment on the angle steel around the high-voltage lines and then control the movement of the equipment to climb the high-voltage lines, which significantly reduces the risk of operation and improves the safety of the operation process.

[0042] Reference Figure 1 When the device is mounted on the high-voltage line via the two drive wheels 7, the extension of the telescopic component 6 controls the driven wheel 8 to approach the drive wheel 7. The drive wheel 7, in conjunction with the driven wheel 8, clamps the high-voltage line. Subsequently, the device can be moved by the rotation of the drive wheel 7, enabling the device to perform inspection operations on the high-voltage line.

[0043] When inspecting one end of a high-voltage line, the telescopic component 6 is first retracted to increase the distance between the drive wheel 7 and the driven wheel 8 on one side. Then, by rotating the first rotating component 2 and the second rotating component 3, the equipment is controlled to perform a climbing operation to switch to another high-voltage line for inspection.

[0044] Reference Figure 7 When the equipment is mounted on the angle steel by attaching the two baffles 51, the outer wall of the drive wheel 7 is attached to the bottom of the angle steel by the contraction of the telescopic component 6. The drive wheel 7, together with the baffles 51, clamps the angle steel accordingly. Then, the operation of the drive wheel 7 controls the movement of the equipment on the angle steel.

[0045] In summary, this equipment can move on angle steel and high-voltage lines, and can climb on both, facilitating switching to different high-voltage lines for inspection. This improves the equipment's inspection efficiency. Furthermore, since the equipment does not need to travel back and forth, its operating time is effectively extended. In addition, because the equipment has climbing capabilities, operators do not need to be particularly close to high-voltage lines, which effectively improves safety during operation.

[0046] Example 2, refer to Figures 1-5This is the second embodiment of the present invention. Unlike the previous embodiment, the drive wheel 7 includes a third rotating member 71 mounted on the support frame 4 and a wheel body 77 mounted on the rotating end of the third rotating member 71. The third rotating member 71 can be a drive motor or a motor. The wheel body 77 can be driven to rotate by the third rotating member 71. It should be noted that the surface of the wheel body 77 is provided with a groove, and the surface of the driven wheel 8 is also provided with a groove. The grooves can improve the stability of the wheel body 77, the driven wheel 8 and the high-voltage line connection, increase the contact area, and prevent the equipment from falling off when moving on the high-voltage line.

[0047] A limiting plate 78 is fixedly provided on the third rotating component 71. It should be noted that the minimum distance between the limiting plate 78 and the sliding frame 5 is greater than the thickness of the angle steel.

[0048] Reference Figure 7 When the telescopic component 6 retracts, the sliding frame 5 will descend, and the drive wheel 7 and the baffle 51 on the sliding frame 5 will approach each other until the angle steel is clamped. Due to the setting of the limiting plate 78, after the movement, the limiting plate 78 can cooperate with the sliding frame 5 to clamp the edge of the angle steel. The sliding frame 5 and the limiting plate 78 are located on both sides of the edge of the angle steel, which can restrict the posture and position of the sliding frame 5, further increasing stability, so that the baffle 51 and the upper surface of the angle steel remain in a close contact state, increasing the contact area between the wheel body 77 of the drive wheel 7 and the bottom of the angle steel. At this time, the rotation of the wheel body 77 controls the device to move more smoothly on the angle steel.

[0049] Specifically, the drive wheel 7 also includes a central gear 72 located at the rotating end of the third rotating member 71, and a limiting ring 73 located on the third rotating member 71. The outer wall of the central gear 72 is meshed with a transmission gear 74, the side wall of the transmission gear 74 is provided with a pinion 75, and the inner wall of the wheel body 77 is provided with an internal gear ring 76. The pinion 75 and the internal gear ring 76 are meshed together, and the third rotating member 71 can drive the central gear 72 to rotate.

[0050] Furthermore, the internal gear ring 76 and the third rotating member 71 are rotatably connected by a bearing; the end of the third rotating member 71 near the central gear 72 is provided with a support column 731, and the limiting ring 73 is fixedly connected to the third rotating member 71 through the support column 731; the transmission gear 74 is rotatably mounted on the third rotating member 71.

[0051] At least three sets of transmission gears 74 are provided, and multiple transmission gears 74 are arranged in a circumferential manner outside the central gear 72. Multiple transmission gears 74 mesh with the central gear 72, and multiple pinions 75 mesh with the inner wall of the internal gear ring 76.

[0052] The rest of the structure is the same as in Example 1.

[0053] In use, the central gear 72 is rotated by the third rotating component 71. The rotation of the central gear 72 drives the surrounding transmission gears 74 to rotate. Since the central gear 72 has a small diameter and the transmission gears 74 have a large diameter, a speed reduction effect can be achieved. Furthermore, the simultaneous meshing of multiple transmission gears 74 with the central gear 72 can improve the strength and stability of the transmission structure. Then, the pinions 75 on the multiple transmission gears 74 simultaneously mesh with the inner wall of the internal gear ring 76 to achieve secondary speed reduction and ensure stability during the transmission process.

[0054] In summary, drive wheel 7 can maintain high stability during operation.

[0055] Example 3, referring to Figures 1-7 This is the third embodiment of the present invention. Unlike the previous embodiment, the sliding frame 5 is provided with a connecting block 53, and the driven wheel 8 is provided on the connecting block 53. The connecting block 53 and the sliding frame 5 are fixedly connected. The driven wheel 8 and the wheel body 77 can be aligned on the same plane by the support of the connecting block 53.

[0056] Specifically, the driven wheel 8 is provided with a rubber plate 81, and there are two sets of driven wheels 8, with the two sets of driven wheels 8 respectively located at both ends of the rubber plate 81; the two driven wheels 8 are located on both sides of the axis of the wheel body 77. By having the two driven wheels 8 simultaneously close to the outside of the wheel body 77, the stability when clamping the high voltage line can be improved, and the stability of the equipment movement when the wheel body 77 rotates can be improved.

[0057] Driven wheel 8 is connected to connecting block 53 via rubber plate 81.

[0058] The rubber plate 81 provides a certain buffering capacity. The rubber plate 81 itself can generate a certain deformation, which can protect the part where the driven wheel 8 contacts the high-voltage line. In addition, the force of the rubber plate 81 restoring its deformation can maintain the adhesion between the driven wheel 8 and the outer wall of the high-voltage line, and can provide appropriate squeezing force to the high-voltage line, ensuring that the equipment can move on the high-voltage line when the wheel 77 rotates.

[0059] Furthermore, the sliding frame 5 is provided with a through-hole movable groove 54, and the drive wheel 7 is movably located in the movable groove 54; the rotating end of the first rotating member 2 is provided with a connecting seat 21; the connecting seat 21 is bent, and the connecting seat 21 and the bottom of the second rotating member 3 are fixedly connected; the first rotating member 2 is connected to the second rotating member 3 through the connecting seat 21; the machine body 1 is provided with a detection element 12.

[0060] In this embodiment, the detection component 12 can be a collection of various devices such as detection sensors and image recognition equipment, used to detect the status of high-voltage lines and identify and detect high-voltage lines.

[0061] The support frame 4 is provided with a slide rail 42; the sliding frame 5 is provided with a slider 55; the slider 55 is slidably disposed on the slide rail 42.

[0062] The stability of the sliding frame 5 can be increased by setting up the slide rail 42 and the slider 55.

[0063] The rest of the structure is the same as in Example 2.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
