[0002] Drones are widely used in transmission line inspections. During drone inspection operations, the transmission lines are located in a complex natural environment with mountains, rivers, fields, forests, and other complex environments. Therefore, when drones inspect transmission lines, they will take off and recover through drone landing cabins to achieve the effect of regular inspections.

At the same time, a pressurized pipe 2 is fixed on one side of the inner wall of the cleaning liquid tank, and a one-way valve 1 is also provided on the surface of the pressurized pipe 2. A pressurized pipe 1 coaxially opposite to the pressurized pipe 2 is fixed on the surface of the UAV landing cabin. The pressurized pipe 1 is connected to the pressurized pipe 2, and a camshaft is fixed in the middle of the positive and negative threaded rods. A connecting rod is hinged on the camshaft, and a piston rod 2 is hinged on the other end of the connecting rod. A pressurized tube 3 is fixed to one side of the inner cavity surface of the UAV landing cabin, and one end of the piston rod 2 is coaxially inserted into the interior of the pressurized tube 3.

[0011] The transmission line inspection drone of the present invention has the following advantages:

[0012] 1. This is a transmission line inspection drone. When the drone takes off for inspection, the motor drives the forward and reverse threaded rods to open the hatch.

[0033] The disclosure below provides many different embodiments or examples to implement different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present invention. In addition, the embodiments of the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0034] like Figure 1-Figure 3 and Figure 6As shown, a transmission line inspection drone of the present invention includes a drone 3 for inspecting lines, through which the lines in a specific area can be inspected by flight, and a patrol camera 32 for patrol is also arranged on one side of the belly of the drone 3. The patrol camera 32 is arranged in a sealed and waterproof structure, and a pair of landing and taking-off frames 31 for support are symmetrically arranged on both sides of the belly of the drone 3.

[0035] At the same time, the storage and landing of the drone 3 is carried out through the drone landing cabin 1. The drone landing cabin 1 can be fixed at the starting point of the inspection area. After the drone 3 inside the drone landing cabin 1 takes off, the inspection can be carried out. The drone landing cabin 1 is a top-opening structure to facilitate the storage of the drone 3. Two openable hatches 2 are placed above the opening, and a threaded tube 23 is fixed at the bottom edge of the hatch 2. The threaded tube 23 is threadedly connected by the forward and reverse threaded rods 11. At the same time, the two ends of the forward and reverse threaded rods 11 penetrate the surface of the drone landing cabin 1. Therefore, after the forward and reverse threaded rods 11 are rotated, the two hatches 2 above the drone landing cabin 1 can be moved toward each other to open or close.

[0036] like Figure 2-Figure 6 As shown, a motor 12 is integrally connected to one end of the positive and negative threaded rod 11, and the motor 12 is fixedly connected to the surface of the drone landing cabin 1. A cleaning liquid tank 4 is fixedly arranged on the surface of the drone landing cabin 1 below the hatch 2, and the interior of the cleaning liquid tank 4 is arranged in a hollow structure. At the same time, a pressurized pipe 2 42 is fixed on one side of the inner wall of the cleaning liquid tank 4, and a one-way valve 1 421 is also arranged on the surface of the pressurized pipe 2 42, and the flow of gas can be controlled by the one-way valve 1 421. A pressurized pipe 1 14 is fixed on the surface of the drone landing cabin 1, which is coaxial with the pressurized pipe 2 42, and the pressurized pipe 1 14 is connected to the pressurized pipe 2 42.

[0037] A push plate 21 is fixed at one edge of the bottom surface of the hatch cover 2, and a piston rod 22 is provided on one side of the surface of the push plate 21 coaxially with the pressure tube 14. Therefore, when the piston rod 22 is inserted into the inside of the pressure tube 14, the gas inside the pressure tube 14 can enter the inside of the hatch cover 2 through the one-way valve 421, thereby increasing the pressure inside the hatch cover 2. The inside of the hatch cover 2 is also filled with a solution that can remove stains on the surface of the inspection camera 32. The solution is added through the filling cap 43 threadedly connected to the surface of the cleaning liquid tank 4.

[0038] A lifting platform 5 capable of lifting and displacing is provided inside the UAV landing cabin 1. The lifting platform 5 is lifted and displaced by an electric lifter 51 provided below. When the electric lifter 51 is operated, the lifting platform 5 can be lifted and displaced. At the same time, a spray head 44 is provided on one side above the lifting platform 5. The spray head 44 is arranged opposite to the surface of the inspection camera 32. The two sides of the outer surface of the spray head 44 are connected to the bottom surface of the cleaning liquid tank 4 through a hose 41. A spray port 441 is provided on the surface of the spray head 44 opposite to the surface of the inspection camera 32. The spray port 441 faces the inspection camera 32. Therefore, when the UAV 3 in the area needs to take off for inspection, the motor 12 is running at this time. After the motor 12 is running, it can drive the positive and negative threaded rod 11 set on one side. As the positive and negative threaded rod 11 rotates, the two relative hatch covers 2 can be displaced away from each other. After the hatch cover 2 moves, the piston rod 22 provided thereunder can move to the inside of the pressurized pipe 14, and supply compressed gas to the inside of the cleaning liquid tank 4, thereby increasing the pressure inside the cleaning liquid tank 4. After the pressure of the cleaning liquid tank 4 increases, the solution inside the cleaning liquid tank 4 can enter the spray head 44 through the hose 41, and be sprayed out from the spray port 441, and then sprayed onto the surface of the inspection camera 32. Since the solution sprayed out of the spray port 441 has a certain pressure, it can have a certain cleaning effect on the surface of the inspection camera 32.

[0039] like Figure 6-Figure 8 As shown, a camshaft 111 is fixed at the middle of the positive and negative threaded rod 11, and a connecting rod 13 is hinged on the camshaft 111, and a piston rod 2 152 is hinged on the other end of the connecting rod 13, and a pressurizing tube 3 15 is fixed on one side of the inner cavity surface of the UAV landing cabin 1, and one end of the piston rod 2 152 is coaxially inserted into the inside of the pressurizing tube 3 15. Therefore, when the positive and negative threaded rod 11 rotates to open the hatch 2, the piston rod 2 152 can continuously compress the space inside the pressurizing tube 3 15 through the camshaft 111 and the connecting rod 13.

[0040] At the same time, a one-way valve 151 is provided on the outer peripheral surface of the pressurized pipe 3 15, and the air flow inside the pressurized pipe 3 15 can be controlled by the one-way valve 151. A base 154 is fixed on one side of the inner cavity bottom surface of the UAV landing cabin 1, and a top pipe 155 is fixed above the base 154. An air pipe 153 is provided between the end of the top pipe 155 and the bottom surface of the pressurized pipe 3 15, and the top pipe 155 and the pressurized pipe 3 15 can be connected through the air pipe 153.

[0041] An air chamber 52 is fixed on one side above the lifting platform 5, and the surface of the air chamber 52 is fixedly connected to the other side of the surface of the spray head 44. A lifting port 522 is provided through the bottom surface of the air chamber 52, and the lifting port 522 can be inserted into the top pipe 155. A gas port 156 is provided near the upper part of the outer peripheral surface of the top pipe 155, and the gas in the pressurized pipe 3 15 can be supplied into the interior of the air chamber 52 through the gas port 156.

[0042] A baffle plate 1 53 is arranged above the opening of the lift port 522, and limiting posts 54 are fixed on both sides of the inner cavity bottom surface of the air chamber 52. One end of the limiting post 54 passes through the baffle plate 1 53, and a spring member 55 is sleeved on the outer circumference of the limiting post 54 above the baffle plate 1 53. The spring member 55 can block and seal the lift port 522 through the baffle plate 1 53 after the top pipe 155 is separated from the lift port 522.

[0043] The surface of the air chamber 52 facing the inspection camera 32 is provided with a blowing port 521, through which the compressed gas inside the air chamber 52 can be discharged, and a baffle plate 2 56 is fixed on one side above the baffle plate 1 53, and the baffle plate 2 56 can block the surface of the blowing port 521. An air duct 442 is provided through the center of the spray head 44, through which the airflow blown out of the blowing port 521 can pass. Therefore, when the hatch cover 2 is opened by rotating the forward and reverse threaded rod 11, the rotation of the forward and reverse threaded rod 11 causes the piston rod 2 152 to continuously compress the space inside the pressure tube 3 15, and then the gas inside the pressure tube 3 15 enters the interior of the air chamber 52 through the air pipe 153 and the top pipe 155, and then the pressure inside the air chamber 52 is continuously increased. As the hatch cover 2 is opened and the lifting platform 5 moves upward, the top pipe 155 is withdrawn from the lifting port 522, and the baffle 1 53 is immediately displaced downward and blocks the lifting port 522. While the baffle 1 53 moves downward, the baffle 2 56 is lowered together, and then the blowing port 521 can be unblocked, and the compressed air flow inside the air chamber 52 can be blown to the surface of the inspection camera 32 through the blowing port 521, so that the water stains on the surface of the inspection camera 32 can be blown away, thereby improving the inspection clarity of the drone 3.

[0044] like Figure 6-Figure 8 As shown, moving grooves 510 are respectively provided on both sides of the upper surface of the lifting platform 5, and slide grooves 59 are also provided on both sides of the moving grooves 510, through which the clamping plate 58 can be slidably arranged above the lifting platform 5, and the sliders 581 provided on both sides of the bottom of the clamping plate 58 are slidably arranged in the slide grooves 59, and the threaded block 582 fixed at the bottom center is arranged inside the moving grooves 510. Then the clamping plate 58 can slide towards each other on the surface of the lifting platform 5.

[0045] A rotatable threaded rod 57 is provided inside both sides of the lifting platform 5, and the threaded rod 57 is threadedly connected to the threaded block 582, and a gear 571 is fixedly connected to one end of the threaded rod 57, and the gear 571 is meshedly connected to a rack 16 extending upward from the bottom surface of the UAV landing cabin 1. When the drone 3 needs to land and return to the drone landing cabin 1 after the inspection is completed, the visual recognition system of the drone 3 captures and recognizes it, and then the drone 3 lands above the raised lifting platform 5. As the drone 3 lands smoothly, the lifting platform 5 slowly descends through the electric lifter 51. After the lifting platform 5 descends, the gear 1 571 provided on both sides of the lifting platform 5 is meshed and connected with the rack 1 16, and then the threaded rod 57 provided on one side of the outer surface of the gear 1 571 rotates. After the threaded rod 57 rotates, the clamps 58 provided on both sides of the upper surface of the lifting platform 5 can be displaced toward each other at the same time, and then the clamps 58 push the landing frame 31, so that the inspection camera 32 provided under the drone 3 can be aimed at the spray head 44, and then the spray head 44 can clean the inspection camera 32, and the landing frame 31 can be fixed by the clamps 58. As the lifting platform 5 rises, its clamps 58 can be displaced in the opposite direction, which is convenient for the drone 3 to take off.

[0046] like Figure 2 and Fig.11 As shown, since some power transmission lines are around forest areas, and the edge of these forest areas provides a variety of habitats for birds, the drone 3 may be affected by flying birds when it needs to take off for inspection regularly. A number of rotating holes 24 are opened on the surface of the hatch 2, and a rotating rod 6 that can rotate is coaxially arranged inside the rotating hole 24. At the same time, a bird-repelling mirror 61 for driving away birds is fixed on the upper part of the outer circumference of the rotating rod 6. As the bird-repelling mirror 61 rotates to reflect sunlight, it plays a role in driving away birds.

[0047] At the same time, a gear 2 62 is fixed at the bottom of the rotating rod 6, and a rack 2 17 is fixed at the upper edge of one side of the outer surface of the UAV landing cabin 1. A rotatable pulley 25 is coaxially arranged inside the rotating hole 24 near the edge of one side of the bottom of the cabin cover 2, and a gear 3 251 is arranged at the end of the pulley 25 to mesh with the rack 2 17. At the same time, a belt 26 is sleeved between the two pulleys 25. A rotatable shaft 63 is arranged between the gear 2 62 and the gear 3 251, and the crown gears 631 arranged at both ends of the shaft 63 are meshed with the gear 2 62 and the gear 3 251. Therefore, when the drone 3 inside the drone landing cabin 1 needs to take off, the hatch 2 moves to both sides. When the hatch 2 moves, the gear three 251 provided on one side of the hatch 2 rotates. As the gear three 251 rotates, the belt 26 can drive the gear three 251 on the other side to rotate. Then, under the rotation of the gear three 251, the rotating rod 6 can be driven through the rotating shaft 63 and the crown gear 631. After the rotating rod 6 rotates, the rotating bird-repelling mirror 61 can achieve a certain bird-repelling effect.

[0048] The working principle of a transmission line inspection drone: When the drone 3 is ready to take off for an inspection mission, the motor 12 starts and drives the forward and reverse threaded rods 11. As the forward and reverse threaded rods 11 rotate, it causes the two relatively positioned hatch covers 2 to move away from each other. During the process of opening the hatch cover 2, the piston rod 22 located below it moves accordingly and enters the pressurized tube 14. This movement of the piston rod 22 will inject compressed gas into the cleaning liquid tank 4, thereby increasing the pressure in the tank. As the internal pressure of the cleaning liquid tank 4 increases, the cleaning solution contained therein is pushed by the pressure and transported to the spray head 44 through the connected hose 41. Finally, the cleaning liquid is sprayed out from the spray port 441 of the spray head 44 at a certain pressure, directly acting on the lens surface of the inspection camera 32, thereby achieving the effect of cleaning the lens;

[0049] As the forward and reverse threaded rods 11 rotate, the hatch 2 begins to open. At the same time, this action also causes the piston rod 2 152 to move inside the pressurized tube 3 15, compressing the space inside it. Due to the compression of the piston rod 2 152, the gas in the pressurized tube 3 15 is squeezed out and enters the air chamber 52 through the air pipe 153 and the top pipe 155, causing the pressure in the air chamber 52 to gradually rise. As the hatch 2 is fully opened, the lifting platform 5 moves upward. At this time, the top pipe 155 is pulled out of the lifting port 522, and at the same time, the baffle 1 53 moves downward to close the opening. At the same time, the baffle 2 56 also moves downward, which will make the air outlet 521 unobstructed. Therefore, the gas previously stored in the air chamber 52 and compressed can be discharged at a higher speed through the air outlet 521 and blown directly onto the surface of the inspection camera 32. This high-speed airflow can effectively remove the residual moisture or other fine impurities on the surface of the camera, ensuring that the camera lens remains dry and clean, thereby improving the quality and clarity of image acquisition when the drone performs inspection tasks;

[0050] When the drone 3 completes the inspection mission and is ready to return to the drone landing cabin 1, it will use its own visual recognition system to locate and confirm the landing position. Once the raised lifting platform 5 is accurately located, the drone 3 will land smoothly on it. After the drone 3 successfully lands and stabilizes, the electric lifter 51 will drive the lifting platform 5 to slowly descend. During the descent of the lifting platform 5, the gear 1571 located on both sides of the platform begins to mesh with the rack 16 fixed in the landing cabin. As this process occurs, the threaded rod 57 connected to the outside of the gear 1571 also begins to rotate. The rotation of the threaded rod 57 causes the splints 58 set on both sides of the upper surface of the lifting platform 5 to move toward the center, that is, to approach each other. Through this relative movement of the splints 58, they can gently but firmly push and fix the landing frame 31 at the bottom of the drone 3. This not only ensures the safe fixation of the drone 3, but also enables the inspection camera 32 installed under the drone to be aimed at the spray head 44, so as to facilitate subsequent cleaning operations;

[0051] Finally, when the drone 3 inside the drone landing cabin 1 is ready to take off, the hatch 2 first moves to both sides. At the same time as the hatch 2 starts to move, the gear three 251 installed on one side also starts to rotate. Through the connection of the belt 26, the rotation of this gear three 251 can synchronously drive the gear three 251 at the corresponding position on the other side. As the gear three 251 rotates, it is also connected to it through the rotating shaft 63, and drives the rotation of the crown gear 631. The crown gear 631 further transmits power to the rotating rod 6, causing the rotating rod 6 to rotate accordingly. A bird-repelling mirror 61 is installed on the rotating rod 6, and as the rotating rod 6 rotates, the bird-repelling mirror 61 will also rotate. The design of the bird-repelling mirror 61 usually includes the effect of reflecting light or generating visual interference. Such a rotational movement can effectively deter birds from approaching the drone landing area and reduce their potential threat to the safety of drone operations.
