Description

Technical Field

[0001] This invention relates to the field of power transmission line construction technology, specifically to a drone device for removing floating foreign objects from 35 kV power transmission lines. Background Technology

[0002] With the development of the national power industry, more and more overhead power lines have emerged. Due to human or natural factors, foreign objects, such as kites and plastic bags, often hang from these lines. When foreign objects appear on energized high-voltage overhead lines, they pose a significant danger and can easily lead to unplanned line outages. Therefore, it is necessary to remove these hanging foreign objects from the power lines promptly to eliminate safety hazards. However, because overhead power lines are high above the ground, they are difficult to remove. While engineering vehicles can be used to reach a certain height, working on energized lines is challenging. Furthermore, many lines are not located near roads, but rather in remote areas where vehicles have difficulty accessing them. All of these factors contribute to the difficulty of removing hanging foreign objects from overhead power lines. To address these problems, some solutions using drones have emerged, such as drones equipped with laser de-object removal devices or drones equipped with gasoline canisters and combustion jet devices. However, these devices are extremely expensive, generally costing over 500,000 yuan, with high maintenance costs and large size, making manual handling in the field inconvenient.

[0003] A search revealed a foreign object removal device for power transmission lines, as disclosed in CN205092513U. This device includes a bracket for fixing to an aircraft. The bracket holds a gas tank, a jetting device, an electric control valve, and a nozzle. The gas tank contains flammable gas. The inlet of the jetting device is connected to the outlet of the gas tank. The outlet of the jetting device is connected to the nozzle via a gas supply pipe. The control valve is located on the gas supply pipe. An ignition device is located at the nozzle's jet outlet. The ignition device includes a heater, a driver for driving the heater, and a first remote controller for controlling the driver's opening and closing. The heater is located at the nozzle's jet outlet. The device also includes a second remote controller for controlling the electric control valve's opening and closing.

[0004] Although the aforementioned patent document describes a foreign object removal device for power transmission lines that can remove suspended foreign objects from power lines, it still has certain problems in its use. Since the device is installed on a drone, it is difficult to adjust the drone to a precise position when operating it, making it impossible for the nozzle to be aimed at the foreign objects suspended on the power line. Furthermore, once the device is fixed to the drone, the spray angle of the nozzle cannot be adjusted. Summary of the Invention

[0010] Preferably, the lifting worm gear is fixedly installed on the side wall of the lifting sleeve, the lifting worm gear is meshed with the lifting worm, the lifting worm is fixedly installed on the output shaft end of the lifting motor, and the lifting screw is fixedly installed on the upper end face of the mounting plate.

[0011] Preferably, there are two sets of lifting worm gears, which are respectively located on the front and rear sides of the lifting worm, and the spiral directions of the lifting screws on the front and rear sides are opposite.

[0012] Preferably, the opening and closing mechanism includes a positioning plate, a transmission rod, an opening and closing motor, a first pulley, a belt, a second pulley, a bidirectional threaded rod, an opening and closing frame, a limiting block, and a support shaft. The positioning plate is fixedly installed on the upper end face of the mounting plate, and the transmission rod is rotatably installed between the positioning plates on the left and right sides. The opening and closing motor is fixedly installed on the upper end face of the mounting plate through a frame. The bidirectional threaded rod is rotatably installed in the inner cavity of the positioning frame, and the limiting block is threadedly installed on the left and right sides of the side wall of the bidirectional threaded rod.

[0013] Preferably, the first pulley is fixedly installed in the middle of the side wall of the transmission rod, the second pulley is fixedly installed in the middle of the side wall of the bidirectional threaded rod, the first pulley is connected to the second pulley via a belt, the output shaft end of the opening and closing motor is fixedly connected to the transmission rod, the limiting block is slidably installed on the side walls of the opening and closing frame on the left and right sides, and the opening and closing frames on the left and right sides are rotatably connected by the support shaft.

[0014] Preferably, the cleaning mechanism includes an external gear ring, a drive gear, a light wheel, an extension rod, a flamethrower, and a cleaning motor. The external gear ring is fixedly installed on the outer side wall of the opening and closing frame. The drive gear is placed on the right side of the opening and closing frame. A light wheel is fixedly installed between the drive gears on the front and rear sides. The extension rod is slidably installed on the side wall of the light wheel. The flamethrower is fixedly installed on the side wall of the extension rod at the end away from the light wheel. The cleaning motor is rotatably installed on the side wall of the opening and closing frame via a rotating bracket.

[0015] Preferably, the output shaft end of the cleaning motor is fixedly connected to the drive gear, the drive gear is meshed with the external gear ring, a movable groove is provided on the side wall of the opening and closing frame, the extension rod slides in the inner cavity of the movable groove, a guide rod is fixedly installed on the side wall of the extension rod, and the guide rod slides in the inner cavity of the movable groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when the drone equipment is working, it can be operated by a remote controller to fly the drone to the vicinity of the power transmission cable that needs to be cleaned. Then, by starting the lifting motor, the lifting worm gear is rotated. Since the lifting worm wheels are respectively set on the front and rear sides of the lifting worm gear and are meshed with the lifting worm gear, the lifting worm gear will drive the lifting worm wheels to rotate continuously, and drive the lifting sleeve to rotate. The lifting screw is threaded into the inner cavity of the lifting sleeve. With the cooperation of the lower mounting plate, when the lifting sleeve rotates, the lifting screw can drive the mounting plate to move up and down, making the distance between the opening and closing frame on the left and right sides and the power transmission cable closer.

[0017] 2. This invention, by starting the opening and closing motor, causes the transmission rod to drive the first pulley to rotate. Under the transmission action of the belt, the first pulley can cause the second pulley to rotate. Since a bidirectional threaded rod is fixedly installed in the inner cavity of the second pulley, the bidirectional threaded rod can rotate at this time. Because the threads on the left and right sides of the bidirectional threaded rod are opposite in direction, the opening and closing frames on the left and right sides are rotatably connected by a support shaft. Under the action of the limiting blocks on the left and right sides, the limiting blocks can drive the opening and closing frames on the left and right sides to rotate around the support shaft, thereby tightening the opening and closing frames and forming a closed loop for power transmission. After the cable is wrapped and limited, and the opening and closing frames on both sides are tightened, the cleaning motor is started to make the drive gear rotate. Since the drive gear is meshed with the external gear ring, the cleaning motor is rotatably mounted on the side wall of the opening and closing frame through the rotating bracket, and the extension rod slides in the inner cavity of the movable groove through the guide rod. At this time, the drive gear can drive the light wheel to slide on the outer wall of the opening and closing frame, thereby making the flamethrower move on the inner ring of the opening and closing frame to adjust the spray angle of the flamethrower. This can quickly burn and remove floating objects on the power transmission cable, thereby greatly improving the work efficiency of workers. Attached Figure Description

[0020] 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, and 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.

[0021] Please see Figures 1-6 This invention provides a technical solution for a drone device for removing floating foreign objects from 35 kV transmission lines: A drone device for removing floating foreign objects from a 35 kV transmission line includes a drone body 1, a bottom footplate 2 fixedly installed at the foot end of the drone body 1, an auxiliary hanging ring 3 fixedly installed on the upper side wall of the drone body 1, and a top plate 4 fixedly installed on the side wall of the foot of the drone body 1. It also includes: Mounting plate 5, with a positioning bracket 6 fixedly installed in the middle of the lower end face of mounting plate 5; The lifting mechanism 7 is located inside the top plate 4 and is used to adjust the height of the mounting plate 5. The opening and closing mechanism 8 is located on the upper surface of the mounting plate 5 and is used to clamp the power transmission cable. Cleaning mechanism 9 is located below mounting plate 5 and is used to remove floating debris from the surface of power transmission cables.

[0022] It should be noted that, with the auxiliary hanging ring 3 fixed to the upper side wall of the drone body 1, after the work is completed, the worker only needs to insert a long wooden stick into the auxiliary hanging ring 3 to easily and quickly retrieve the entire drone equipment, which facilitates quick maintenance.

[0023] Furthermore, the lifting mechanism 7 includes a lifting sleeve 71, a lifting screw 72, a lifting motor 73, a support plate 74, a lifting worm 75, and a lifting worm wheel 76. The lifting sleeve 71 is rotatably installed in the inner cavity of the top plate 4, the lifting screw 72 is threadedly installed in the inner cavity of the lifting sleeve 71, the lifting motor 73 is fixedly installed on the upper end face of the bottom pedal 2 through the frame, the support plate 74 is fixedly installed on the upper end face of the bottom pedal 2 on the left and right sides, and the lifting worm 75 is rotatably installed between the support plates 74 on the left and right sides. The lifting worm gear 76 is fixedly installed on the side wall of the lifting sleeve 71. The lifting worm gear 76 is meshed with the lifting worm 75. The lifting worm 75 is fixedly installed on the output shaft end of the lifting motor 73. The lifting screw 72 is fixedly installed on the upper end face of the mounting plate 5. There are two sets of lifting worm gears 76, which are respectively located on the front and rear sides of the lifting worm 75, and the spiral directions of the lifting screws 72 on the front and rear sides are opposite.

[0024] It should be noted that the drone is operated by a remote controller to fly to the vicinity of the power transmission cable to be cleared. Then, the lifting motor 73 is started to rotate the lifting worm 75. Since the lifting worm gears 76 are respectively set on the front and rear sides of the lifting worm 75 and are meshed with the lifting worm 75, the lifting worm 75 will drive the lifting worm gears 76 to rotate continuously, and drive the lifting sleeve 71 to rotate. The lifting screw 72 is threaded into the inner cavity of the lifting sleeve 71. With the cooperation of the lower mounting plate 5, when the lifting sleeve 71 rotates, the lifting screw 72 can drive the mounting plate 5 to move up and down, making the opening and closing frame 87 on the left and right sides closer to the power transmission cable.

[0025] Furthermore, the opening and closing mechanism 8 includes a positioning plate 81, a transmission rod 82, an opening and closing motor 83, a first pulley 84, a belt, a second pulley 85, a bidirectional threaded rod 86, an opening and closing frame 87, a limiting block 88, and a support shaft 89. The positioning plate 81 is fixedly installed on the upper end face of the mounting plate 5, and the transmission rod 82 is rotatably installed between the positioning plates 81 on the left and right sides. The opening and closing motor 83 is fixedly installed on the upper end face of the mounting plate 5 through the frame. The bidirectional threaded rod 86 is rotatably installed in the inner cavity of the positioning frame 6, and the limiting block 88 is threadedly installed on the left and right sides of the side wall of the bidirectional threaded rod 86. The first pulley 84 is fixedly installed in the middle of the side wall of the transmission rod 82, and the second pulley 85 is fixedly installed in the middle of the side wall of the double-threaded rod 86. The first pulley 84 is connected to the second pulley 85 by a belt. The output shaft end of the opening and closing motor 83 is fixedly connected to the transmission rod 82. The limit block 88 is slidably installed on the side walls of the opening and closing frame 87 on the left and right sides. The opening and closing frames 87 on the left and right sides are rotatably connected by a support shaft 89.

[0026] It should be noted that when the worker starts the opening and closing motor 83, the transmission rod 82 drives the first pulley 84 to rotate. Under the transmission action of the belt, the first pulley 84 can cause the second pulley 85 to rotate. Since the inner cavity of the second pulley 85 is fixedly installed with a bidirectional threaded rod 86, the bidirectional threaded rod 86 can rotate at this time. Since the thread directions on the left and right sides of the bidirectional threaded rod 86 are opposite, the opening and closing frames 87 on the left and right sides are rotatably connected by the support shaft 89. Under the cooperation of the limiting blocks 88 on the left and right sides, the limiting blocks 88 can drive the opening and closing frames 87 on the left and right sides to rotate around the support shaft 89 as the node, thereby tightening the opening and closing frames 87 and forming a closed loop to cover and limit the power transmission cable.

[0027] Furthermore, the cleaning mechanism 9 includes an external gear ring 91, a drive gear 92, a light wheel 93, an extension rod 94, a flamethrower 95, and a cleaning motor 96. The external gear ring 91 is fixedly installed on the outer side wall of the opening and closing frame 87. The drive gear 92 is placed on the right side of the opening and closing frame 87. The light wheel 93 is fixedly installed between the drive gears 92 on the front and rear sides. The extension rod 94 is slidably installed on the side wall of the light wheel 93. The flamethrower 95 is fixedly installed on the side wall of the extension rod 94 at the end away from the light wheel 93. The cleaning motor 96 is rotatably installed on the side wall of the opening and closing frame 87 via a rotating bracket 961. The output shaft of the cleaning motor 96 is fixedly connected to the drive gear 92, and the drive gear 92 is meshed with the external gear ring 91. The side wall of the opening and closing frame 87 is provided with a movable groove 871, and the extension rod 94 slides in the inner cavity of the movable groove 871. A guide rod 941 is fixedly installed on the side wall of the extension rod 94, and the guide rod 941 slides in the inner cavity of the movable groove 871.

[0028] It should be noted that after the opening and closing frames 87 on both sides are tightened, the drive gear 92 is rotated by starting the cleaning motor 96. Since the drive gear 92 is meshed with the outer gear ring 91, the cleaning motor 96 is rotatably mounted on the side wall of the opening and closing frame 87 through the rotating bracket 961, and the extension rod 94 slides in the inner cavity of the movable groove 871 through the guide rod 941. At this time, the drive gear 92 can drive the light wheel 93 to slide on the outer wall of the opening and closing frame 87, thereby allowing the flamethrower 95 to move on the inner ring of the opening and closing frame 87 to adjust the spray angle of the flamethrower 95. This can quickly burn and remove floating objects on the power transmission cables, thereby greatly improving the work efficiency of the workers.

[0029] Working principle: When the drone is working, it can be operated by a remote controller to fly to the vicinity of the power transmission cable that needs to be cleaned. Then, by starting the lifting motor 73, the lifting worm 75 is rotated. Since the lifting worm wheels 76 are respectively set on the front and rear sides of the lifting worm 75 and are meshed with the lifting worm 75, the lifting worm 75 will drive the lifting worm wheels 76 to rotate continuously, and drive the lifting sleeve 71 to rotate. The lifting screw 72 is threaded into the inner cavity of the lifting sleeve 71. With the cooperation of the lower mounting plate 5, when the lifting sleeve 71 rotates, the lifting screw 72 can drive the mounting plate 5 to move up and down, so that the opening and closing frame 87 on the left and right sides is closer to the power transmission cable. Then, the worker starts the opening and closing motor 83, which causes the transmission rod 82 to drive the first pulley 84 to rotate. Under the transmission of the belt, the first pulley 84 can cause the second pulley 85 to rotate. Since the inner cavity of the second pulley 85 is fixedly installed with a bidirectional threaded rod 86, the bidirectional threaded rod 86 can rotate at this time. Since the threads on the left and right sides of the bidirectional threaded rod 86 are opposite, the opening and closing frames 87 on the left and right sides are rotatably connected by the support shaft 89. Under the cooperation of the limiting blocks 88 on the left and right sides, the limiting blocks 88 can drive the opening and closing frames 87 on the left and right sides to rotate with the support shaft 89 as the node, thereby tightening the opening and closing frames 87 and forming a closed loop to cover and limit the power transmission cable. After the opening and closing frames 87 on both sides are tightened, the drive gear 92 is rotated by starting the cleaning motor 96. Since the drive gear 92 is meshed with the outer gear ring 91, the cleaning motor 96 is rotatably mounted on the side wall of the opening and closing frame 87 through the rotating bracket 961, and the extension rod 94 slides in the inner cavity of the movable groove 871 through the guide rod 941. At this time, the drive gear 92 can drive the light wheel 93 to slide on the outer wall of the opening and closing frame 87, thereby allowing the flamethrower 95 to move on the inner ring of the opening and closing frame 87 to adjust the spray angle of the flamethrower 95. This can quickly burn and remove floating objects on the power transmission cable, thereby greatly improving the work efficiency of the workers. After removing floating debris from the power transmission cables, the worker only needs to reverse the transmission rod 82 by opening and closing the motor 83. With the cooperation of the bidirectional threaded rod 86, the limit block 88, and the support shaft 89, the opening and closing frames 87 on both sides can be opened quickly. Then, the worker can operate the drone body 1 to fly away from the entire drone equipment. Through the auxiliary hanging ring 3 fixed on the upper side wall of the drone body 1, after the work is completed, the worker only needs to insert a long wooden stick into the auxiliary hanging ring 3 to easily and quickly hover and pick up the entire drone equipment, which is convenient for the worker to maintain quickly.
