Technical Field

[0001] The invention relates to the technical field of boiler four-tube monitoring, and in particular to a boiler four-tube monitoring device based on an unmanned aerial vehicle. Background Art

[0002] Boiler four tubes refer to the four key heat exchange components in the boiler of a thermal power plant, namely the water wall, superheater, reheater and economizer. Since the four tubes of the boiler are under the pressure and chemical composition of the working fluid inside and face the high temperature, erosion and wear environment outside, it is easy to leak. Leakage will lead to unplanned downtime, increase maintenance workload and operating costs, and may even cause safety accidents in serious cases. In order to avoid leakage in the four tubes of the boiler, it is necessary to regularly inspect the four tubes of the boiler.

[0003] The existing four-tube boilers are inspected by drones to improve the efficiency of inspection. However, in strong winds, due to the poor wind resistance of the drone inspection device, the drone cannot effectively inspect the four tubes near the boiler, which delays the inspection process and fails to detect potential problems with the four-tube boiler in time, increasing the operational risk of the boiler.

Source 26, a fixed block 3 is fixedly connected to the bottom of the drone body 1, a return spring 31 is fixedly connected to the surface of the fixed block 3, a limit rod 32 is fixedly connected to the surface of the return spring 31, an operating rod 35 is fixedly connected to the bottom of the limit rod 32, a first cylinder 33 is rotatably connected to the surface of the connecting box 23, a connecting ring 34 is fixedly connected to the piston rod of the first cylinder 33, the wind-resistant mechanism installs the connecting box 23 on the bottom of the drone body 1 through the spring sheet 22, counterweights the drone body 1, improves the stability of the drone, and the two sets of adjusting blades 25 at the bottom of the connecting box 23 can adjust the rotation angle, so that the adjusting blades 25 provide a wind-resistant opposite force to the drone body 1 during rotation, avoids the tilting phenomenon of the drone body 1 during flight, makes the drone body 1 fly smoothly, and avoids the drone body 1 being unable to fly in strong winds.

[0026] Furthermore, a guiding mechanism is provided on the surface of the UAV body 1, and the guiding mechanism includes a first gear 4, the first gear 4 is rotatably connected to the surface of the UAV body 1, a second cylinder 41 is rotatably connected to the surface of the first gear 4, a wind guide plate 42 is rotatably connected to the surface of the first gear 4, a piston rod of the wind guide plate 42 is rotatably connected to the surface of the second cylinder 41, a second motor 43 is fixedly connected to the surface of the UAV body 1, and a second gear 44 is fixedly connected to the output shaft of the second motor 43. The guiding mechanism can use the second cylinder 41 to guide wind flow, reduce the jitter and shaking caused by the direct impact of wind on the main structure of the UAV, thereby improving the flight stability of the UAV.

[0027] Furthermore, two groups of spring sheets 22 are provided and fixedly connected to both sides of the connection box 23. A circular hole is opened on the surface of the spring sheet 22. The spring sheet 22 deforms so that the fixing bolt 2 passes through the circular hole of the spring sheet 22. The spring sheet 22 rotates on the drone body 1 through the fixing bolt 2. The spring sheet 22 drives the connection box 23 to rotate at the bottom of the drone body 1. The nut 21 limits the position of the spring sheet 22 to ensure the stability of the rotation of the spring sheet 22 and the connection box 23 at the bottom of the drone body 1.

[0028] Furthermore, a cavity is provided inside the drone body 1, and the first motor 24 and the power supply 26 are located on the cavity of the connection box 23. The power supply 26 directly supplies power to the first motor 24 and the first cylinder 33, thereby reducing the power consumption of the power supply inside the drone body 1 and ensuring the flight time of the drone body 1.

Since the limit rod 32 is restricted by the limit rod 32, the first cylinder 33 will drive the connecting box 23 to rotate at the bottom of the drone body 1, thereby changing the angle of the adjustment fan blade 25 at the bottom of the drone body 1.

[0030] Furthermore, the first gear 4 and the second gear 44 are meshed with each other, the second motor 43 drives the second gear 44 to rotate through the output shaft, and the second gear 44 drives the second cylinder 41 to rotate through the first gear 4. The diameter of the first gear 4 is greater than the diameter of the second gear 44. The second cylinder 41 changes its direction on the drone body 1 by rotating, thereby facilitating the guidance of wind in any wind direction.

[0031] Furthermore, the second cylinder 41 is in the shape of a fish fin, and the wind guide plate 42 drives the second cylinder 41 to rotate on the surface of the first gear 4 through the piston rod. The second cylinder 41 can be rotated to the surface of the first gear 4 to form a fold, thereby reducing the impact in a windless environment.

[0032] Working principle: In the case of strong wind, the spring sheet 22 deforms to allow the fixing bolt 2 to penetrate the circular hole of the fixing bolt 2, and then the nut 21 is threadedly connected to the fixing bolt 2. The spring sheet 22 drives the connecting box 23 to rotate at the bottom of the drone body 1. The connecting box 23 increases the overall weight of the drone body 1 and improves the stability of the drone body 1. The first cylinder 33 is rotated on the connecting box 23, and the limit rod 32 is connected to the connecting ring 34 of the piston rod of the first cylinder 33 through the elastic force of the reset spring 31. The first cylinder 33 drives the connecting ring 34 to move through the piston rod. Under the restriction, the first cylinder 33 will drive the connecting box 23 to rotate at the bottom of the drone body 1, thereby changing the angle of the adjusting blades 25 at the bottom of the drone body 1, and the first motor 24 drives the adjusting blades 25 to rotate through the output shaft. The adjusting blades 25 provide a reverse thrust to the drone body 1 through rotation, thereby avoiding the tilt of the drone body 1 and ensuring the stability of the drone body 1 during flight, so that the drone body 1 can detect the four tubes of the boiler in a windy environment, so that the monitoring device can detect potential problems with the four tubes of the boiler in time, reducing the operating risk of the boiler.

[0033] The second cylinder 41 is driven to rotate on the first gear 4 by the piston rod of the wind guide plate 42, so that the second cylinder 41 is perpendicular to the surface of the first gear 4, and then the second gear 44 is driven to rotate by the output shaft of the second motor 43. The second gear 44 drives the first gear 4 to rotate on the surface of the drone body 1, and the first gear 4 drives the second cylinder 41 to rotate on the surface of the drone body 1, so that the second cylinder 41 can guide the wind flow on the surface of the drone body 1, reduce the shaking and shaking caused by the direct impact of wind on the main structure of the drone, and thus improve the flight stability of the drone.
