Technical Field
[0001] This invention relates to the field of power line inspection equipment technology, specifically to a traction-type overhead power line observation device. Background Technology
[0002] Transmission lines bear the critical responsibility of transmitting electricity over long distances. However, during long-term operation, these lines are subject to the combined effects of multiple factors, including environmental stress, electrical stress, and mechanical stress, making them highly susceptible to various defects. Among these, strand breakage is the most common and poses the greatest threat. These defects reduce the mechanical strength of the line, leading to corona discharge and arc erosion. If these defects are not detected in time, they may develop into line breaks under extreme conditions such as icing or strong winds, causing widespread power outages.
[0003] Traditional manual aerial inspections suffer from high-altitude safety risks, low efficiency, and insufficient data objectivity; drone hovering inspections suffer from unstable images and incomplete data collection (or require drones to have overhead cameras); fixed detection devices have poor adaptability and high installation and maintenance costs. Mobile observation devices have revealed several engineering problems in practical applications: under vibration conditions, there is a risk of wheel derailment and the mobile observation device falling; when encountering obstacles on the line, manual control is required to overcome them. Therefore, there is a need to provide a traction-type overhead power line observation device. Summary of the Invention
[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, and in view of the above-mentioned shortcomings, the present invention provides a traction-type overhead power line monitoring device.
[0005] This invention provides a traction-type overhead power line monitoring device, comprising: A traction-supporting frame with an overall double-n configuration that can be placed across overhead power lines; The front and rear ends of the frame are equipped with roller assemblies for mounting on overhead power lines. The roller assemblies support the frame to move on the overhead power lines via V-grooved wheels. The front and rear ends of the frame are also provided with rolling clamping mechanisms for rolling clamping and locking overhead power lines. The frame is equipped with an upper line guiding and braking mechanism. The upper line guiding and braking mechanism guides the overhead power line to the clamping rollers and V-groove rollers through a downward-opening Y-shaped adjustable guiding and braking component that gradually narrows from bottom to top. The guide rod of the Y-shaped adjustable guiding and braking component supports controlled clamping and braking of the overhead power line. The rack is provided with installation positions for observation equipment, supporting the installation of observation equipment at 120° intervals.
[0006] Furthermore, the frame includes: two n-shaped support frames facing downwards and arranged opposite each other; a connecting beam is provided between the tops of the two n-shaped support frames; the connecting beam is provided with traction components and installation positions for observation equipment; a connecting seat is provided on the outer side of the bottom of each n-shaped support frame; a fixing plate is provided between corresponding connecting seats of two n-shaped support frames; and the installation positions for observation equipment are provided on the fixing plate; the three observation positions are arranged at 120° intervals around the overhead power line.
[0007] Furthermore, the roller assembly includes: two opposing roller bearing seats disposed at the upper part of each n-type support frame, a roller shaft disposed between the two opposing roller bearing seats of the same n-type support frame, a V-grooved wheel rotatably disposed on the roller shaft, and two support limiting plates disposed between the roller shaft and the n-type support frame.
[0008] Furthermore, the rolling clamping mechanism includes: a driving device; a first gear connected to the output end of the driving device; two guide mounting plates arranged opposite each other, each guide mounting plate having a sliding groove; two first racks slidably disposed in corresponding sliding grooves, the first racks being meshed with the first gear; and clamping rollers disposed at the ends of each of the first racks.
[0009] Furthermore, a pressure sensor is provided on the shaft of one of the clamping rollers. The pressure sensor is electrically connected to a controller, and the controller is electrically connected to the motor drive circuit of the drive device. The output angle of the drive device is adjusted according to the feedback force of the pressure sensor.
[0010] Furthermore, the sidewall of the clamping roller is concave and arc-shaped, and the clamping roller is made of insulating and wear-resistant nitrile rubber.
[0011] Furthermore, the Y-shaped adjustable guided braking assembly includes: A slider with an adjustable and fixed position is mounted on a slide rail connected to the frame; an electric telescopic rod is mounted on the slider; a first guide rod is slidably mounted on the slider; and a second guide rod is fixed on the slider. The first and second guide rods form a guide structure that opens downwards and gradually contracts from bottom to top. The movable end of the electric telescopic rod is connected to the first guide rod.
[0012] Furthermore, the motor drive circuit of the electric telescopic pole is electrically connected to a controller. The controller adjusts the distance between the first guide rod and the second guide rod according to the diameter of the overhead power line, changes the width of the vertical guide gap between the first guide rod and the second guide rod to adapt to overhead power lines of different diameters, and then adjusts the position of the vertical guide gap by adjusting the position of the slider.
[0013] Furthermore, the Y-shaped adjustable guided braking assembly includes: The frame is connected to a parallel double slide rail. Two sliders are slidably arranged on the double slide rail. A second rack is arranged on the opposite side of the two sliders. A first guide rod and a second guide rod are arranged on the two sliders respectively. The first guide rod and the second guide rod form a guide structure that opens downward and gradually narrows from bottom to top. The two second racks mesh and rotate between the two slide rails to form an adjusting second gear. An electric telescopic rod is installed next to the double slide rails. The movable end of the electric telescopic rod is connected to the first guide rod, or the output shaft of the brake encoder motor is connected to the second gear by adjusting the output shaft.
[0014] Furthermore, the drive circuit of the electric telescopic pole or the adjusting brake encoder motor is electrically connected to the controller. The controller drives the electric telescopic pole or the adjusting brake encoder motor to adjust the distance between the first guide rod and the second guide rod according to the diameter of the overhead power line, thereby changing the width of the vertical guide gap between the first guide rod and the second guide rod to adapt to overhead power lines of different diameters.
[0015] The technical solutions provided in the embodiments of the present invention have the following advantages compared with the prior art: To avoid image instability, the traction-type overhead power line monitoring device of this application adopts a method of moving along the overhead power line. In this way, the distance between the camera and the line is relatively constant, the acquired image is stable, and it is more conducive to subsequent image defect analysis.
[0016] This application employs a frame-supported traction system. The traction, combined with the guidance and braking mechanisms, allows the UAV to be re-launched online without requiring high docking precision, eliminating the need for manual operation and facilitating repositioning when encountering obstacles. Because this application uses a traction-based system, the drive is not self-driven, and braking is inconvenient due to inertia. Therefore, the online guidance and braking mechanisms of this application also provide braking, supporting braking under traction conditions.
[0017] The rolling clamping mechanism of this application for rolling clamping and locking overhead power lines can prevent the device from slipping off the line. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0024] Example 1 like Figure 1 As shown, the present invention provides a traction-type overhead power line monitoring device, comprising: A double-n-shaped frame 1, capable of straddling an overhead power line, provides a mounting platform for each component. Specifically, the frame 1 includes: two n-shaped support frames 11 facing downwards, with a connecting beam 12 between their tops. The connecting beam 12 houses traction components and installation positions for observation equipment. Each n-shaped support frame 11 has outwardly flared J-shaped support legs 13 at its bottom. Two symmetrical, triangular connecting seats 14 are located on the outer side of the bottom of each n-shaped support frame 11. A fixing plate 15 is positioned between corresponding connecting seats 14 of the two n-shaped support frames 11, with installation positions for observation equipment on the fixing plate 15. The connecting beam 12 is equipped with traction components to support connecting ropes for traction. The three observation positions are arranged at 120° intervals around the overhead power line.
[0025] The frame 1 is made of insulating material, such as epoxy resin, which has insulating, high strength and corrosion resistance properties.
[0026] The traction component can be connected to a drone via a rope, and the drone can pull the traction-type overhead power line observation device along the overhead power line.
[0027] The front and rear ends of the frame 1 are provided with roller assemblies 2 for attaching to the overhead power lines. The roller assemblies 2 move on the overhead power lines through V-groove wheel support devices.
[0028] Specifically, such as Figure 2 As shown, the roller assembly 2 includes: two opposing roller bearing seats 21 disposed at the upper part of each n-shaped support frame; a roller shaft 22 disposed between the two opposing roller bearing seats 21 of the same n-shaped support frame; a V-grooved wheel 23 rotatably disposed on the roller shaft 22; and two support limiting plates 24 disposed between the roller shaft 22 and the n-shaped support frame 11. The support limiting plates 24 limit the movement range of the V-grooved wheel 23 on the one hand, and form a triangular configuration with the roller shaft and the n-shaped support frame on the other hand, thereby enhancing the overall structural strength of the device.
[0029] The front and rear ends of the frame 1 are also provided with a rolling clamping mechanism 3 for rolling clamping overhead power lines. The rolling clamping mechanism 3 includes: a driving device; a first gear connected to the output end of the driving device; two guide mounting plates arranged opposite each other, each guide mounting plate having a sliding groove; two first racks slidably arranged in the corresponding sliding grooves, the first racks being meshed with the first gear; and clamping rollers arranged at the ends of each first rack. The driving device drives the first gear to rotate, and the rotational motion is converted into the linear translational motion of the two first racks through the first gear-first rack transmission mechanism, thereby driving the two clamping rollers to move closer or further apart, realizing the clamping or release of the overhead power line.
[0030] In the specific implementation process, such as Figure 3 As shown, the rolling clamping assembly 3 includes: two C-shaped connecting frames 31 disposed at the upper part of the n-shaped support frame 11; an encoder motor 32 is installed between the two C-shaped connecting frames 31 on the same n-shaped support frame 11 via a mounting plate as a driving device; the output shaft of the encoder motor 32 is provided with a first gear 33; two guide mounting plates 34 with sliding grooves are disposed between the two C-shaped connecting frames on the same n-shaped support frame 11 and are arranged opposite to each other; a first rack 35 is slidably disposed in the sliding groove; the first rack 35 sliding on the two guide mounting plates 34 is coupled to the first gear 33 from both sides of the first gear; clamping rollers 36 are respectively provided at the ends of the two first racks 35; the encoder motor 32 drives the first rack 35 to translate by rotating the first gear clockwise and counterclockwise, so that the clamping rollers 36 on the two first racks move closer or further apart; when they move closer, they clamp the overhead power line; when they move further apart, they release the line and leave space for the overhead power line to enter the gap between the two clamping rollers 36 for line insertion. The clamping roller 36 has a concave arc-shaped sidewall and is made of insulating and wear-resistant nitrile rubber. It can be adapted to overhead conductors with a wire diameter of 5mm-40mm to achieve adaptive rolling clamping.
[0031] In the specific implementation process, a pressure sensor is installed on the shaft of one of the clamping rollers 36. The pressure sensor is electrically connected to a controller, and the controller is electrically connected to the motor drive circuit of the encoder motor 32. The controller adjusts the output angle of the encoder motor according to the feedback force of the pressure sensor.
[0032] The frame 1 is equipped with an overhead power line guiding and braking mechanism 4. When the device is placed on an overhead power line, the overhead power line guiding and braking mechanism 4 guides the overhead power line between the two clamping rollers 36 and the V-groove wheel 23 through a downward-opening, gradually converging Y-shaped adjustable guiding and braking assembly. In particular, when transferring the power line via a drone, as long as the line falls within the range of the Y-shaped adjustable guiding and braking assembly, high precision is not required.
[0033] In the specific implementation process, such as Figure 4 and Figure 5 As shown, the upper guide and braking mechanism 4 includes: an inverted T-shaped frame 41 fixed to the top connecting beam 12 of the frame 1; a slide rail 45 is provided on the bottom crossbar of the inverted T-shaped frame 41; and a Y-shaped adjustable guide and braking assembly is provided on the slide rail 45 in an adjustable position. The Y-shaped adjustable guide and braking assembly includes: A slider 46 slides on a slide rail 45, an electric telescopic rod 42 is mounted on the slider 46, a first guide rod 43 is slidably mounted on the slider 46, and a second guide rod 44 is fixed on the slider 46; the first guide rod 43 and the second guide rod 44 form a downward-opening guide structure that gradually contracts from bottom to top, and the movable end of the electric telescopic rod 42 is connected to the first guide rod 43.
[0034] The motor drive circuit of the electric telescopic pole 42 is electrically connected to the controller. The controller adjusts the distance between the first guide rod 43 and the second guide rod 44 according to the controller, changes the width of the vertical guide gap between the first guide rod 43 and the second guide rod 44 to adapt to overhead power lines of different diameters, and then adjusts the position of the vertical guide gap by adjusting the position of the slider 46.
[0035] When the device is placed on the overhead power line, the overhead power line is guided to the clamping rollers 36 and the V-groove wheel 23 by the Y-type adjustable guide braking assembly; and during the movement, the first guide rod 43 is driven by the electric telescopic rod 42 to move toward the second guide rod 44 to clamp the overhead power line and achieve braking.
[0036] In another example, the upper guide and braking mechanism 4 includes: an inverted T-shaped frame 41 fixed to the top connecting beam 12 of the frame 1, with parallel double slide rails provided on the bottom crossbar of the inverted T-shaped frame 41; the Y-shaped adjustable guide and braking assembly includes: Two sliders are slidably mounted on the double slide rails. Second racks are respectively mounted on opposite sides of the two sliders. A first guide rod 43 and a second guide rod 44 are respectively mounted on the two sliders. The first guide rod 43 and the second guide rod 44 form a guide structure that opens downward and gradually narrows from bottom to top. The two second racks mesh with a second gear that is rotatably mounted between the double slide rails. An electric telescopic rod is mounted on the bottom crossbar of the inverted T-shaped frame 41. The movable end of the electric telescopic rod 42 is connected to the first guide rod 43, or it can be connected to the first gear through the output shaft of the encoder motor.
[0037] Due to the engagement of the second gear and the second rack, the first guide rod 43 and the second guide rod 44 move synchronously towards or away from each other, maintaining the vertical gap between them always in the center. The drive circuit of the electric telescopic rod 42 or the adjusting brake encoder motor is electrically connected to a controller. The controller drives the electric telescopic rod 42 or the adjusting brake encoder motor according to the diameter of the overhead power line to adjust the distance between the first guide rod 43 and the second guide rod 44, changing the width of the vertical guide gap between them to accommodate overhead power lines of different diameters. The controller controls the first guide rod 43 and the second guide rod 44 to move towards each other, clamping the overhead power line to achieve braking.
[0038] The frame 1 supports observation devices 5 arranged at 120° intervals. Examples of these devices include imaging devices such as visible light and infrared cameras, or ultrasonic probes. Specifically, one imaging device is mounted on the connecting beam 12, and the other two are mounted on two fixed plates 15, respectively, covering the circumferential observation needs of the overhead power line and providing comprehensive observation.
[0039] The center of gravity of the traction-type overhead power line monitoring device of this application is located below the V-shaped groove wheel 23 to maintain stability.
