Description

Technical Field

[0001] The present application relates to the technical field of power transmission and distribution line maintenance, and in particular to a power supply line cleaning device. Background Art

[0002] Transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines are composed of line towers, conductors, insulators, line hardware, guy wires, tower foundations, grounding devices, etc., and are erected above the ground. When overhead power lines are in use, in order to ensure the service life of the power cables, it is necessary to regularly inspect and maintain the cables of the power lines, and remove branches near the cables or debris on the cables, such as kites, hydrogen balloons, plastic bags, etc. The debris on the overhead power lines is generally removed using a laser obstacle remover or a drone equipped with a flamethrower.

[0003] For example, the Chinese invention patent with the patent number CN114852337A discloses a drone accessory for cleaning debris on power transmission lines. Through the oil outlet pipe, rotating rod and flame-spraying rod, in conjunction with a micro-motor, a driving wheel and a driven wheel, it can spray fire and burn foreign objects when it is necessary to clean foreign objects on the power transmission line, making it convenient to clean foreign objects. In addition, the micro-motor can be started to rotate the flame-spraying rod, so as to facilitate the adjustment of the direction of the flame spraying and facilitate the cleaning of foreign objects. However, in high-altitude environments, due to the small number of surrounding obstructions, the ejected flame is more affected by wind interference. Under wind interference, the flame may rebound to other parts of the drone or accessories, causing them to be burned and damaged. At the same time, it will also increase the difficulty of drone control and reduce maintenance efficiency. Summary of the invention

DETAILED DESCRIPTION

[0048] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with examples and drawings. The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.

[0049] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 An embodiment of the present application provides a power line cleaning device, which includes a drone 1, a flamethrower mechanism 2 and a windproof mechanism; the flamethrower mechanism 2 is connected to the drone 1, and the flamethrower mechanism 2 has a flamethrower port that can spray flames; the windproof mechanism is connected to the flamethrower mechanism 2, and the windproof mechanism has a plurality of air outlets arranged around the flamethrower port, and the flamethrower port and the air outlet have the same direction.

[0050] When the embodiment of the present application is in use, the drone 1 is controlled to fly to a predetermined position, the flamethrower mechanism 2 is turned on to allow the flame to spray flames from the flamethrower, and the windproof mechanism is turned on at the same time to allow the air outlet to continuously exhaust air to form an airflow with a fixed direction around the flamethrower. The drone 1 is controlled to bring the flamethrower close to the debris on the line to achieve cleaning.

[0051] The embodiment of the present application provides a power line cleaning device. After a plurality of air outlets are arranged around a crater, the controllable airflow discharged from the air outlet can form a wind wall around the crater. The wind wall can form a certain obstacle to the natural wind, thereby preventing the natural wind from directly interfering with the flame at the crater and causing the flame to rebound to the drone 1, thereby ensuring the system reliability of the power line cleaning device; at the same time, the plurality of air outlets can achieve a cleaning effect on some lightweight and easy-to-clean debris to avoid the burning of the debris, which saves fuel on the one hand, and can prevent the transmission and distribution lines from being burned on the other hand, thereby greatly reducing the probability of secondary maintenance of the lines.

[0052] In the embodiment of the present application, the flamethrower mechanism 2 and the windproof mechanism can be electrically connected to the drone 1 respectively so that the operator can control the operation of the flamethrower mechanism 2 and the windproof mechanism together through the remote control of the drone 1; of course, in other embodiments, the flamethrower mechanism 2 and the windproof mechanism can be respectively configured with wireless communication modules for controlled actions.

[0053] In the embodiment of the present application, the same orientation of the flammable port and the air outlet means, for example, that the flammable port and the air outlet are simultaneously facing left or simultaneously facing right, and does not specifically mean that the flammable port and the air outlet are parallel. That is to say, the orientations of the flammable port and the air outlet may form an angle, but both are facing the same direction.

[0054] In the embodiment of the present application, the UAV 1 can be any aircraft in the prior art that can drive the flame-throwing mechanism 2 and the wind-proof mechanism to fly.

[0055] In some optional embodiments, the plurality of air outlets are evenly distributed around the circumference.

[0056] In the embodiment of the present application, multiple air outlets are arranged in a circularly evenly distributed manner to make the wind wall more stable, reduce the probability of air flow turbulence in local areas, and have a better blocking effect on natural wind.

[0057] In some optional embodiments, the air outlet faces radially outward relative to the flame outlet.

[0058] In the embodiment of the present application, the air outlet is radially outward relative to the crater, so that the wind wall formed by the airflow at the air outlet can have a larger range, that is, the overall shape of the wind wall is similar to a truncated cone, thereby further reducing the disturbance of the natural wind to the flame at the crater, ensuring that the flame has better stability.

[0059] In some optional embodiments, please refer to Figure 2 , Figure 3 and Figure 5 The windproof mechanism includes a fan 13, an air outlet pipe 10, a guide cover 11 and an air outlet nozzle 12; the fan 13 is connected to the flame-spraying mechanism 2, and the fan 13 can adopt a commonly used axial flow fan 13; the air outlet pipe 10 is connected to the flame-spraying mechanism 2 to achieve the fixation of the air outlet pipe 10, and one end of the air outlet pipe 10 is connected to the fan 13 to guide the airflow generated by the fan 13; the guide cover 11 is connected to the other end of the air outlet pipe 10, so that the airflow in the air outlet pipe 10 can be introduced into the guide cover 11; the air outlet nozzle 12 is connected to the guide cover 11 and communicated with the inside of the guide cover 11, which means that multiple air outlet nozzles 12 are connected to the air outlet pipe 10 through the guide cover 11.

[0060] In the embodiment of the present application, the airflow generated by the fan 13 first enters the air deflector 11 to be collected, and then is diverted from the air deflector 11 to each air outlet nozzle 12 to be discharged through the air outlet on the air outlet nozzle 12; this arrangement can avoid the need to connect each air outlet nozzle 12 to the fan 13, can simplify the structure, and has a relatively low weight, so that it is suitable for a working environment driven by the drone 1. At the same time, a system with fewer pipes has a smaller risk of blockage and better system stability.

[0061] In some optional embodiments, a conical flow-guiding convex surface is constructed in the air guide cover 11 , and the top of the conical flow-guiding convex surface is arranged opposite to the other end of the air outlet pipe 10 .

[0062] In the embodiment of the present application, when the top of the conical guide convex surface is arranged opposite to the other end of the air outlet pipe 10, the airflow in the air outlet pipe 10 can be directly shot to the top of the conical guide convex surface, and then the airflow is smoothly dispersed through the conical surface, so that the airflow pressure, flow rate and other parameters in each air outlet nozzle 12 are basically consistent, thereby making the formed wind wall shape more stable, ensuring that it has a better resistance to natural wind.

[0063] In some optional embodiments, there is a distance between the air outlet and the flamethrower in the direction of the outlet centerline of the flamethrower; in the working state, in the flamethrower's flame spraying direction, the air outlet is located behind the flamethrower.

[0064] In the embodiment of the present application, after a distance is arranged between the air outlet and the flare, the radius of the truncated cone-shaped wind wall at the corresponding position of the flare is larger, which means that it can be within a larger protection range, thereby further reducing the probability of natural wind causing significant interference to the flame.

[0065] In some optional embodiments, please refer to Figure 2 , Figure 3 and Figure 5 The flamethrower mechanism 2 includes a mounting seat 4, a fuel tank 16, a fuel delivery pipe 5 and a flamethrower head; the mounting seat 4 is connected to the UAV 1, and the mounting seat 4 is generally in the shape of a rectangular parallelepiped; the fuel tank 16 is arranged on the mounting seat 4, and the fuel tank 16 can be detachably connected to the mounting seat 4 to ensure the convenience of maintenance; the fuel delivery pipe 5 is connected to the fuel tank 16, wherein a fuel delivery pump 15 can be arranged between the fuel tank 16 and the fuel delivery pipe 5, which means that the fuel delivery pipe 5 is connected to the fuel tank 16 through the fuel delivery pump 15, and the fuel delivery pump 15 It can be connected to the fuel tank 16 through the suction pipe 31, so that the fuel pressure, flow rate, etc. can be accurately controlled by the fuel delivery pump 15, which is convenient for adjusting the flame size. Of course, in other embodiments, the fuel tank 16 can be configured as a fuel tank, and the on-off and flow rate of the fuel can be controlled by configuring a flow control valve on the fuel delivery pipe 5; the flamethrower head is connected to the fuel delivery pipe 5, and an igniter 9 is configured on the flamethrower head, wherein a one-way valve 33 can be installed between the flamethrower head and the fuel delivery pipe 5 to prevent safety accidents caused by fuel reflux. The fuel in the fuel tank 16 is pumped out by the fuel delivery pump 15 and enters the fuel delivery pipe 5. The fuel reaches the flamethrower head through the delivery pipe through the one-way valve 33, and the fuel is ignited by the ignition device to generate a continuous flame to burn the debris.

[0066] When the flamethrower mechanism 2 has a fuel delivery pipe 5, the air outlet pipe 10 and the air guide cover 11 in the wind protection mechanism can be sleeved on the fuel delivery pipe 5, and the air guide cover 11 as a whole can be set to a cone shape, so as to facilitate the layout of the air outlet nozzle 12; at the same time, the structure can be simplified and the total weight of the structure can be reduced, thereby reducing the load of the drone 1 and reducing the probability of accidents.

[0067] In some optional embodiments, see Figure 4 and Figure 5 The fuel delivery pipe 5 is connected to the mounting seat 4 through a connecting frame 14, wherein the connecting frame 14 is connected to the mounting seat 4 through an adjusting component. When the adjusting component is controlled to move, it drives the connecting frame 14 to rotate on the mounting seat 4, and the fuel delivery pipe 5 is connected to the fuel tank 16 through a material delivery telescopic hose 32.

[0068] In the embodiment of the present application, when the position of the drone 1 does not correspond to the position of the debris, the connecting frame 14 can be driven to rotate by the adjustment component, thereby adjusting the position of the flamethrower head, reducing the control work of the drone 1 and the alignment work of the drone 1 and the debris to simplify the maintenance process and improve the maintenance efficiency. Among them, the fuel delivery pipe 5 can be connected to the fuel delivery pump 15 through the material delivery telescopic hose 32, and the deformation of the material delivery telescopic hose 32 can adapt to the rotation of the fuel delivery pipe 5; correspondingly, the air outlet pipe 10 can be connected to the fan 13 through the air delivery telescopic hose 30.

Specifically, both ends of the transmission shaft 7 are rotatably connected to the cavity wall of the transmission cavity 6, so that the transmission shaft 7 can rotate freely around its own axis in the transmission cavity 6; the worm wheel 19 is coaxially matched with the transmission shaft 7, so that the worm wheel 19 can rotate synchronously with the transmission shaft 7; the worm 18 is rotatably connected to the mounting seat 4 And cooperate with the worm gear 19 for transmission. Specifically, a support plate 20 can be set on the cavity wall of the transmission cavity 6, one end of the worm 18 is rotatably connected to the support plate 20, and a driving motor 17 is arranged on the worm 18. The other end of the worm 18 can be connected to the cavity wall of the transmission cavity 6 through the driving motor 17, so that when the worm 18 is driven to rotate by the driving motor 17, the worm 18 can drive the worm gear 19 to rotate, and then the worm gear 19 can rotate synchronously with the transmission shaft 7, and the connecting frame 14 drives the fuel delivery pipe 5 to move to adjust the position of the flamethrower head.

[0070] In some optional embodiments, see Figure 7 to Figure 10, the mounting seat 4 is connected to the drone 1 through a quick connection component 3, and the quick connection component 3 includes an upper connecting plate 21 and a lower connecting plate 22; the upper connecting plate 21 is connected to the drone 1. In actual implementation, the upper connecting plate 21 can be connected to the bottom of the drone 1 by bolts to ensure the stability of the connection between the two. A plurality of threaded columns 23 are arranged on the upper connecting plate 21, wherein the upper connecting plate 21 can be a square plate, and the number of the threaded columns 23 can be configured as four, and the four threaded columns 23 are respectively located at the four corners of the upper connecting plate 21, and a non-rotating limit groove 24 is provided on the end surface of the threaded column 23. In actual implementation, the non-rotating limit groove 24 can be a rectangular groove for easy processing and manufacturing. In other embodiments, the non-rotating limit groove 24 can also be configured as a triangular groove, a star groove, an elliptical groove, etc.; the lower connecting plate 22 can be set to a square plate the same as the upper connecting plate 21, and a plurality of threaded columns 23 are respectively arranged on the lower connecting plate 22. The support column 25 corresponding to the position of the column 23, that is, the number of the support columns 25 can also be set to four, and the four support columns 25 are respectively located at the four corners of the lower connecting plate 22. In actual implementation, the support column 25 can be constructed as a cylinder, and a non-rotating limit block 28 adapted to the non-rotating limit groove 24 is provided on the support column 25. Specifically, the non-rotating limit block 28 can be arranged on the end face of the support column 25, and the non-rotating limit block 28 can be constructed as a rectangular block adapted to the shape of the non-rotating limit groove 24. A threaded sleeve 26 that can be threadedly matched with the threaded column 23 is also movably sleeved on the support column 25, that is, the threaded sleeve 26 can rotate freely on the threaded column 23. For example, a limit plate 27 can be coaxially fixed on the support column 25, and the outer diameter of the limit plate 27 is slightly smaller than the inner diameter of the threaded sleeve 26.

[0072] In some optional embodiments, a first camera 34 may be installed on the drone 1 to search for foreign objects on the line, and a second camera 35 may be installed on the air outlet duct 10 to monitor the flame status in real time.

[0073] During actual implementation, the UAV 1 is communicatively connected to a remote control device, a control box is provided on the mounting seat 4, a control panel and a wireless communication module are provided in the control box, the control panel is communicatively connected to the remote control device via the wireless communication module, the control panel is electrically connected to the first camera 34, the second camera 35, the drive motor 17, the fuel delivery pump 15, the igniter 9 and the fan 13 respectively, the flight of the UAV 1 is controlled by the remote control device, and instructions are sent to the control panel via the remote control device, and the control panel controls the operation of the drive motor 17, the fuel delivery pump 15, the igniter 9 and the fan 13.

[0074] In summary, in the power supply line cleaning device provided in the embodiment of the present application, the fuel stored in the fuel tank 16 can be gas or fuel oil. When cleaning foreign objects on the high-voltage transmission and transformation line, the drone 1 drives the flame-throwing mechanism 2 to fly near the foreign objects, and makes the flame-throwing pipe head on the flame-throwing mechanism 2 aim at the foreign objects. The foreign objects are viewed through the second camera 35 on the air outlet pipe 10 to facilitate the flame-throwing pipe head to aim at the foreign objects. Then, the fuel delivery pump 15 works, and the fuel in the fuel tank 16 is extracted through the suction pipe 31, and the fuel is input into the fuel delivery system through the delivery telescopic hose 32. The flame is ejected from the flamethrower 11 through the nozzle 14 and the nozzle 15 is used to burn the foreign objects on the high-voltage transmission and transformation line. At the same time, the fan 13 inputs the air into the air duct in the air outlet 10 through the air supply telescopic hose 30, and finally ejects the air from each air outlet 12 to form a wind wall, which can prevent the ejected flame from rebounding under the action of the external wind, thereby avoiding damage to the drone 1, protecting the first camera 34 and the second camera 35, and preventing the burned foreign objects from floating onto the drone 1.

[0075] When clearing horizontally floating and long foreign objects, the drone 1 is controlled to fly above the line, and then the drive motor 17 is controlled to work to drive the worm 18 to rotate, the rotation of the worm 18 drives the worm wheel 19 to rotate, the rotation of the worm wheel 19 drives the transmission shaft 7 to rotate, and the transmission shaft 7 rotates to enable the connecting frame 14 to drive the fuel delivery pipe 5 to rotate, thereby adjusting the direction of the flamethrower head on the fuel delivery pipe 5 so that the flamethrower head is downwardly aimed at the part of the foreign object wrapped around the high-voltage transmission and transformation line, and then the flamethrower head sprays out flames to align and burn and burn to achieve a clearing effect, and the second camera 35 on the air outlet pipe 10 can move with the rotation of the fuel delivery pipe 5 so that its viewing direction is always consistent with the direction of the flamethrower head.
