Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and in particular to a de-icing device for wind turbine blades. Background Technology

[0002] As the core equipment of wind power generation, wind turbines can convert wind energy into mechanical work and electrical energy. Their main components include blades, generators, and energy storage mechanisms. Since this equipment relies on wind power, it is currently mostly installed in outdoor locations with abundant wind resources. Because the blades are located at high altitudes, they are prone to icing during rain and snow. The ice layer significantly increases the weight of the blades, alters their original shape and airfoil structure, and causes unbalanced loads during rotation. This not only seriously affects power generation efficiency and reduces power output, but also greatly increases the equipment failure rate and shortens the service life of the wind turbine.

[0003] With the maturity of drone technology, drones can be used to carry de-icing fluid and spray it onto the surface of blades at high altitudes. By lowering the freezing point of water, the water droplets attached to the blades are less likely to freeze into ice. For existing ice layers, the de-icing fluid can penetrate the gaps between the ice layer and the blades, accelerating the melting and peeling off of the ice.

[0004] Currently, in wind turbine blade de-icing operations, drones often use parallel nozzles to improve the efficiency of de-icing fluid spraying. High-pressure spraying can quickly cover the blade surface with de-icing fluid. However, when facing blades with different tilt angles, the fixed nozzles limit the spray angle of the de-icing fluid, causing the de-icing fluid to spray onto the blade surface. This necessitates frequent adjustments to the drone's position, resulting in a significant waste of de-icing fluid during the adjustment process. Therefore, this application proposes a wind turbine blade de-icing device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wind turbine blade de-icing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a wind turbine blade de-icing device, comprising a drone, with two sets of frames installed at the bottom of the drone, and a support assembly located below the drone installed on the two sets of frames. A water pump is installed on the support assembly, and the water inlet of the water pump is connected to a second water pipe through a sealing joint, and the water outlet of the water pump is connected to a horizontal first water pipe. A connecting pipe is rotatably connected to the end of the first water pipe away from the water pump, and a rotary joint is rotatably fitted at the junction of the connecting pipe and the first water pipe. An adjustable-angle water storage pipe is connected to the end of the connecting pipe away from the first water pipe, and multiple nozzles are equidistantly installed on the side of the water storage pipe away from the connecting pipe, and a flexible hose fixedly inserted into the connecting pipe is connected to the side of the water storage pipe near the connecting pipe.

[0007] Optionally, the frame consists of two diagonal bars and a crossbar. The tops of the diagonal bars in the two sets of frames are fixedly connected to the four corners at the bottom of the UAV. The support assembly is installed on the crossbar in the two sets of frames. The support assembly includes a support plate and two sets of support frames. The right end of the support plate is set to be vertical. The two sets of support frames are respectively installed at both ends of the bottom of the horizontal part of the support plate, and the bottom of both ends of the support frame is provided with a connecting groove. Two connecting blocks are installed on the top of the crossbar of the two sets of frames. The connecting grooves at the bottom of both ends of the two sets of support frames are respectively fitted into the corresponding connecting blocks, and bolts are inserted through the two ends of the two sets of support frames and the corresponding connecting blocks.

[0008] Optionally, the water pump is installed at the top of the horizontal part of the support plate, and the water inlet end of the bottom of the water pump passes through the support plate. The first water pipe passes through the vertical part at the right end of the support plate, and a reinforcing component sleeved on the connecting pipe is fixedly installed on the right side of the vertical part of the support plate.

[0009] Optionally, the reinforcement assembly includes a reinforcement tube and two reinforcement rods. The reinforcement tube is sleeved outside the connecting tube, and both ends of the inner wall of the reinforcement tube are provided with annular grooves. Bearings are installed in both annular grooves. The outer wall of the connecting tube is fixedly connected to the inner ring wall of the two bearings. The two reinforcement rods are respectively connected to both sides of the reinforcement tube, and the ends of the two reinforcement rods away from the reinforcement tube are fixedly connected to the right side of the vertical part of the support plate. A drive assembly connected to the connecting tube is installed on the top of the reinforcement tube.

[0010] Optionally, the drive assembly includes a servo motor, a gear, and a gear ring. The servo motor is mounted on the top of the reinforcing tube, the gear is mounted on the output end of the servo motor, and the gear ring is fixedly sleeved on the connecting tube and located below the gear, with the bottom end of the gear meshing with the top end of the gear ring.

[0011] Optionally, a first fixing bolt is fixedly installed on both sides of the connecting pipe and on the right side of the reinforcing pipe, and a second fixing bolt is fixedly installed at the middle position on both sides of the water storage pipe. A hydraulic rod is hinged between the two first fixing bolts and the corresponding second fixing bolts. An external hinge connected to the outer wall of the water storage pipe is fixedly installed at the bottom of the connecting pipe at the end away from the first water pipe.

[0012] The beneficial effects of this utility model are:

[0013] The servo motor is started, causing the gear at its output end to mesh with the gear ring on the outer wall of the connecting pipe, rotating the connecting pipe between the reinforcing pipes. This, in turn, causes the water storage pipe at the end of the connecting pipe to rotate, changing the angle of the parallel nozzles on the side wall of the water storage pipe. The angle of the water storage pipe can be precisely adjusted according to the angle of each blade of the wind turbine after it stops, allowing the parallel nozzles to spray de-icing fluid quickly onto the ice layer on the blade surface at a suitable spray angle. This avoids the spray angle being limited due to the fixed nozzles, reduces the number of times the drone needs to be repositioned, and reduces the waste of de-icing fluid.

[0014] The water storage pipe and the connecting pipe are connected by a flexible hose. Under the action of the hydraulic rod, the water storage pipe can rotate around the outer hinge. When the device is not in use, the hydraulic rod drives the water storage pipe to rotate to a parallel state with the connecting pipe, and the water storage pipe is retracted, reducing the overall space occupied by the device and facilitating storage and transportation.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a wind turbine blade de-icing device, including a drone 1. Two sets of frames 2 are mounted on the bottom of the drone 1. Support components 3 located below the drone 1 are mounted on the two sets of frames 2. A water pump 4 is mounted on the support components 3. The inlet end of the water pump 4 is connected to a second water pipe 42 via a sealed joint, and the outlet end of the water pump 4 is connected to a horizontal first water pipe 41. A connecting pipe 43 is rotatably connected to the end of the first water pipe 41 away from the water pump 4. A rotary joint 44 is rotatably fitted at the junction of the connecting pipe 43 and the first water pipe 41. The connecting pipe 43 is located away from the... One end of the first water pipe 41 is connected to an adjustable-angle water storage pipe 6. Multiple nozzles 61 are equidistantly installed on the side of the water storage pipe 6 away from the connecting pipe 43. A flexible hose 62, which is fixedly inserted into the connecting pipe 43, is connected to the side of the water storage pipe 6 near the connecting pipe 43. Through the cooperation of the rotary joint 44 and the drive assembly 7, the connecting pipe 43 can rotate at the end of the first water pipe 41, thereby driving the water storage pipe 6 and the nozzles 61 to adjust their angles to adapt to different tilting blades and improve the de-icing fluid spraying efficiency. The flexible hose 62 connects the water storage pipe 6 and the connecting pipe 43 to ensure smooth liquid delivery during angle adjustment and prevent leakage.

[0025] like Figure 2 and Figure 3As shown, the frame 2 consists of two diagonal bars and a crossbar. The tops of the diagonal bars in the two sets of frames 2 are fixedly connected to the four corners at the bottom of the UAV 1. The support assembly 3 is installed on the crossbar in the two sets of frames 2. The support assembly 3 includes a support plate 31 and two sets of support frames 32. The right end of the support plate 31 is set to be vertical. The two sets of support frames 32 are respectively installed at both ends of the bottom of the horizontal part of the support plate 31. The bottom of both ends of the support frame 32 is provided with a connecting groove 33. The top of the crossbar of the two sets of frames 2 is equipped with two connecting blocks 34. The connecting grooves 33 at the bottom of both ends of the two sets of support frames 32 are respectively fitted into the corresponding connecting blocks 34. Bolts 35 are inserted through the two ends of the two sets of support frames 32 and the corresponding connecting blocks 34. By unscrewing the bolts 35, the support frame 32 can be separated from the frame 2, thereby disassembling the support assembly 3 from the two sets of frames 2. In this way, the water pump 4, the connecting pipe 43 and the water storage pipe 6 on the support assembly 3 can be removed together.

[0026] like Figure 1 and Figure 2 As shown, the water pump 4 is installed at the top of the horizontal part of the support plate 31, and the water inlet end of the bottom of the water pump 4 passes through the support plate 31. The first water pipe 41 passes through the vertical part of the right end of the support plate 31, and a reinforcing component is fixedly installed on the right side of the vertical part of the support plate 31 and sleeved on the connecting pipe 43. The vertical part on the right side of the support plate 31 can support and fix the first water pipe 41, and by setting the reinforcing component, it can provide a certain support and fixation for the connecting pipe 43, making the connecting pipe 43 more stable when rotating and preventing the pipe from shaking and causing leakage.

[0027] like Figure 4 and Figure 5 As shown, the reinforcement assembly includes a reinforcement tube 5 and two reinforcement rods 51. The reinforcement tube 5 is sleeved on the outside of the connecting tube 43, and annular grooves are opened at both ends of the inner wall of the reinforcement tube 5. Bearings 52 are installed in the two annular grooves. The outer wall of the connecting tube 43 is fixedly connected to the inner ring wall of the two bearings 52. The two reinforcement rods 51 are respectively connected to both sides of the reinforcement tube 5, and the ends of the two reinforcement rods 51 away from the reinforcement tube 5 are fixedly connected to the right side of the vertical part of the support plate 31. A drive assembly 7 connected to the connecting tube 43 is installed on the top of the reinforcement tube 5. The bearings 52 on the inner wall of the reinforcement tube 5 can reduce the rotational friction of the connecting tube 43. In conjunction with the two reinforcement rods 51 connected to the support plate 31, the position of the reinforcement tube 5 is fixed.

[0028] like Figure 4 and Figure 5As shown, the drive assembly 7 includes a servo motor 71, a gear 72, and a gear ring 73. The servo motor 71 is mounted on the top of the reinforcing tube 5, the gear 72 is mounted on the output end of the servo motor 71, and the gear ring 73 is fixedly sleeved on the connecting tube 43 and located below the gear 72. The bottom end of the gear 72 is meshed with the top end of the gear ring 73. The servo motor 71 achieves precise rotation of the connecting tube 43 through the meshing of the gear 72 and the gear ring 73, thereby enabling rapid adjustment of the angle of the water storage tube 6 and the nozzle 61.

[0029] like Figure 5 and Figure 6 As shown, first fixing bolts 81 are fixedly installed on both sides of the connecting pipe 43 and on the right side of the reinforcing pipe 5. Second fixing bolts 83 are fixedly installed at the middle position on both sides of the water storage pipe 6. Hydraulic rods 82 are hinged between the two first fixing bolts 81 and the corresponding second fixing bolts 83. An external hinge 84 connected to the outer wall of the water storage pipe 6 is fixedly installed at the bottom of the connecting pipe 43 away from the first water pipe 41. The first fixing bolts 81 and the second fixing bolts 83 can fix the two ends of the hydraulic rods 82 respectively. When the hydraulic rods 82 cooperate with the external hinges 84, the pitch angle of the water storage pipe 6 can be flexibly adjusted. Combined with the rotation of the connecting pipe 43, a three-dimensional angle adjustment capability is formed. When the device is not in operation, the hydraulic rods 82 can drive the water storage pipe 6 to fold parallel to the connecting pipe 43, reducing the size of the device and facilitating transportation and storage.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
