When drones inspect boiler water wall tubes, they need to enter from a boiler observation window of a specific size at high altitude. However, the inspection drones are large in size and the boiler entrance and exit are narrow. In order to ensure the load-bearing capacity and stable flight of the drones, people often use folding rotor drones for inspection. In order to ensure the safety of the inspection drone's take-off and landing, there is an urgent need for a cantilever platform that can realize the drone's high-altitude take-off and landing and is suitable for installation in the boiler's high-altitude window.

[0044] In order to achieve the above technical objectives, the technical solution adopted by the present invention is to disclose a landing platform for a boiler inspection UAV, which is arranged at the high-altitude window of the boiler and its position corresponds to the boiler mouth.

[0045] The landing platform of the boiler inspection drone includes a parking plate 1, a fixing unit 2 and an angle adjustment unit 3;

The fixed unit 2 is used to fix the shutdown board 1 at the boiler mouth position.

The landing platform of the boiler inspection drone is detachable relative to the boiler mouth, which saves space outside the boiler when not in use. The platform is parked stably, which is convenient for starting and stopping the inspection drone.

The left folding plate 11 and the right folding plate 12 are respectively provided with comb teeth, and the comb teeth of the left folding plate 11 and the right folding plate 12 are complementary structures after being installed in place. The left folding plate 11 and the right folding plate 12 can be relatively translated left and right along the axial direction of the comb teeth.

[0052] It should be noted that the folding plate of the landing platform is a overlapping folding plate with a translational sliding structure at both ends. Compared with traditional folding plates, it has the advantages of soft sliding, light weight, and the ability to carry heavier objects. In particular, for situations where the boiler inlet is small, the overlapping folding plate has a small volume when folded and a large area when unfolded, providing protection for the safe landing of the inspection drone.

[0057] The motor shaft of the stepper motor 221 is axially fixedly connected to the ball screw 222. The movable plate 223 is installed on the ball screw 222 and can move along the axial direction of the ball screw 222. The movable plate 223 is connected to the support angle bracket 23. The movable plate 223 pushes the support angle bracket 23 to cooperate with the bent part at the end of the support bracket 21 to complete the clamping of the boiler wall at the boiler mouth position.

[0058] The supporting angle bracket 23 includes a tightening bracket 231 , a connecting piece 232 and a clamping frame 233 . The connecting piece 232 connects the tightening bracket 231 and the clamping frame 233 . The tightening bracket 231 is fixedly connected to the moving plate 223 and is driven to move by the moving plate 223 .

[0060] S1: The shutdown plate 1 is a foldable plate that can be overlapped, and the fixing unit 2 is a self-locking fixing unit 2.

[0061] S2: When the platform is used, the positioning hole of the bent part of the end of the support frame 21 is positioned, connected and fixed with the positioning pin provided on the outer furnace wall of the boiler port.

[0062] S3: The fixing unit 2 adjusts the distance between the movable plate 223 and the support angle bracket 23 and the bent portion at the end of the support bracket 21 through the ball screw 222, and fixes the support bracket 21 by utilizing the clamping force generated by the bent portion at the end of the support bracket 21 and the support angle bracket 23 on the boiler wall at the boiler mouth position.

[0063] S4: After the support frame 21 is fixed, the translational telescopic frame 13 is installed on the support frame 21 through the slider and the slide groove, and the translational telescopic frame 13 is pushed forward along the travel direction of the slide groove to the limit position, and the stopper 24 is rotated to fix the translational telescopic frame 13.

[0065] S6: Complete the installation of the landing platform.

[0066] In some specific embodiments of the present invention, the specific structure of the angle adjustment unit 3 is also disclosed, such as Figure 1 and Figure 4 shown.

[0067] The angle adjustment unit 3 is connected and fixed below the support frame 21 through a spring 33 and rivets.

[0068] The angle adjustment unit 3 includes a worm gear 311 mechanism 31, a cam 321 mechanism 32 and a protective cover 34. The worm gear 311 is installed inside the protective cover 34. The cam 321 mechanism 32 is connected to the worm gear 311 mechanism 31 through a transmission shaft 314. The top of the spring 33 is connected to the support frame 21 through a rivet, and the bottom of the spring 33 is connected to the cam 321 mechanism 32 through a rivet.

[0069] The worm gear 311 mechanism 31 comprises a worm 311 , a worm wheel and a transmission shaft 314 . The worm 311 drives the worm wheel to rotate, and the rotational torque generated by the worm wheel is transmitted to the cam 321 mechanism 32 through the transmission shaft 314 .

[0070] The cam 321 mechanism 32 includes a cam 321 and a support block 322 . The cam 321 relies on the transmission shaft 314 to transmit torque and thus completes rotation. The support block 322 is tangent to the outer edge of the cam 321 , and the extended length of the support block 322 changes with the rotation of the cam 321 .

[0071] Based on the specific structure of the angle adjustment unit 3, the present invention further discloses an angle adjustment method for a landing platform of a boiler inspection drone, which is applied to the landing platform of the above-mentioned boiler inspection drone. The angle adjustment method includes:

[0072] After the landing platform is installed in place, observe the inclination between the landing platform's stop plate 1 and the horizontal ground, and use an angle measuring instrument to measure the inclination angle between the landing platform and the horizontal ground.

[0073] It is stipulated that when the lifting and landing platform is parallel to the horizontal ground, the inclination angle is 180°; when the end of the lifting and landing platform is away from the furnace wall at the boiler mouth and approaches the horizontal ground, the inclination angle is less than 180°; when the end of the lifting and landing platform is away from the furnace wall at the boiler mouth and moves away from the horizontal ground, the inclination angle is greater than 180°.

[0074] When the inclination angle is less than 180°, the worm 311 rotates clockwise, the worm 311 drives the worm wheel to rotate, and then transmits the torque to the cam 321 through the transmission shaft 314. The cam 321 rotates clockwise to drive the support block 322 to extend outward, raising the position of the end of the landing platform to increase the inclination angle.

[0075] When the inclination angle is greater than 180°, the worm 311 rotates counterclockwise, the worm 311 drives the worm wheel to rotate, and then transmits the torque to the cam 321 through the transmission shaft 314. The cam 321 rotates counterclockwise to drive the support block 322 to retract inward, lowering the position of the platform end and completing the reduction of the inclination angle.

[0076] It should be noted that the angle adjustment unit 3 of the landing platform is a cam 321 type angle adjustment unit 3 driven by a worm gear 311 combination, which can accurately adjust the inclination angle between the platform and the horizontal plane, ensuring the stability of the drone's take-off and landing. Compared with the traditional cam 321 angle adjustment unit 3, the angle adjustment unit 3 of the present invention is driven by the worm gear 311, and utilizes the self-locking ability of the worm gear 311 to achieve unidirectional rotation of the transmission shaft 314, ensuring that the cam 321 mechanism 32 will not reverse due to the force on the bottom end of the support block 322.

[0077] Based on the above technical scheme, the present invention discloses a landing platform, installation method and angle adjustment method of a boiler inspection drone. The landing platform of the boiler inspection drone includes a stop plate 1, a fixing unit 2 and an angle adjustment unit 3. The stop plate 1 is a overlapped stop plate 1, the fixing unit 2 is a self-locking fixing unit 2, and the angle adjustment unit 3 is a cam 321 type angle adjustment unit 3 driven by a worm gear 311 combination. The fixing unit 2 is fixed to the boiler opening by clamping force, the stop plate 1 is installed above the fixing unit 2, and can realize synchronous telescopic folding. The angle adjustment unit 3 is located below the fixing unit 2, and the inclination angle of the platform and the horizontal plane can be adjusted by rotating the worm 311. The gain effect of the present invention is: the overlapped stop plate 1 designed by the present invention has the advantages of convenient folding, light weight, uniform load, etc., which meets the needs of taking off and landing drones at high-altitude windows of boilers with limited sizes, and effectively improves the stability of the drone landing platform. In addition, the design of the angle adjustment unit 3 ensures that the inclination angle between the platform and the horizontal plane is within a controllable range, ensuring the safety and stability of the drone's take-off and landing.

The cam rotates clockwise to drive the support block to extend outward, raising the position of the end of the landing platform, thereby completing the increase of the inclination angle; When the inclination angle is greater than 180°, the worm is rotated counterclockwise, and the worm drives the worm wheel to rotate, and then transmits the torque to the cam through the transmission shaft. The cam rotates counterclockwise to drive the support block to retract inward, lower the position of the platform end, and complete the reduction of the inclination angle.
