Description

Technical Field

[0001] This invention relates to the field of wind turbine blade de-icing equipment technology, specifically to a de-icing device. Background Technology

[0002] Icing on wind turbine blades can affect their aerodynamic shape, impairing the aerodynamic function of the airfoil and impacting the safe operation of the turbine. It also increases the load, reduces the unit's power generation efficiency, and shortens the unit's lifespan. When the blades rotate, ice adhering to them may be thrown off, endangering the safety of nearby people and property.

[0003] Ice covering wind turbine blades is difficult to remove. Common methods include air heating for melting ice and chipping away at the blades. Air heating is complex to implement, and since wind turbine blades are made of resin-based composite materials with low thermal conductivity, air heating for melting ice is not only energy-intensive but also inefficient. Chiseling away at the blades can easily damage them, and the ice cover is smooth and seamless, making it difficult to remove. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art. To this end, embodiments of the present invention provide a de-icing device that can spray sodium chloride solution onto ice caps on wind turbine blades to lower the freezing point of the ice caps on the wind turbine blades, thereby removing the ice caps covering the wind turbine blades.

[0005] The de-icing device of this invention includes a frame, a lifting assembly, a liquid collection assembly, and a spraying assembly. The lifting assembly is connected to the frame to drive the frame to take off and land; the liquid collection assembly is disposed on the frame and includes a water storage chamber, a salt storage chamber, and a liquid collection chamber. The water storage chamber can be switched between a connected state and an isolated state, in which it communicates with the salt storage chamber and in which it is isolated from the salt storage chamber. In the connected state, the water storage chamber supplies water to the salt storage chamber to dissolve the solid sodium chloride in the salt storage chamber. The liquid collection chamber is connected to the salt storage chamber to collect the sodium chloride solution. The spraying assembly is connected to the liquid collection chamber to spray the sodium chloride solution onto the ice surface.

[0006] The de-icing device of this invention uses a lifting assembly to drive the frame to a position near the wind turbine blades. A spraying assembly then sprays sodium chloride solution from the collection assembly onto the ice surface near the wind turbine blades to lower the melting point of the ice cap, thus melting the ice and removing it. This de-icing device offers high de-icing efficiency and is less likely to damage the wind turbine blades. During the de-icing process, some of the sodium chloride solution flows on the ice surface under gravity, increasing the contact area between the solution and the ice, and ensuring even coverage, further enhancing de-icing efficiency. Furthermore, the device automatically prepares the sodium chloride solution, reducing operator workload and further improving de-icing efficiency.

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The de-icing device 1 of the present invention will now be described in conjunction with the accompanying drawings.

[0043] like Figure 1 As shown, the de-icing device 1 of this embodiment includes a frame 2, a lifting assembly 3, a liquid collection assembly 4, and a spraying assembly 5. The lifting assembly 3 is connected to the frame 2 to drive the frame 2 to take off and land; the liquid collection assembly 4 is disposed on the frame 2 and includes a water storage chamber 431, a salt storage chamber 451, and a liquid collection chamber 41. The water storage chamber 431 can be switched between a connected state and an isolated state. In the connected state, the water storage chamber 431 supplies water to the salt storage chamber 451 to dissolve the solid sodium chloride in the salt storage chamber 451. The liquid collection chamber 41 is connected to the salt storage chamber 451 to collect the sodium chloride solution; the spraying assembly 5 is connected to the liquid collection chamber 41 to spray the sodium chloride solution onto the ice surface.

[0044] During de-icing of wind turbine blades, the lifting assembly 3 drives the frame 2 to take off and move to the vicinity of the wind turbine blades, so that the water storage chamber 431 is in a connected state, allowing water to be supplied from the water storage chamber 431 to the salt storage chamber 451 to form a sodium chloride solution. The collection chamber 41 collects and stores the sodium chloride solution. The spraying assembly 5 is connected to the collection chamber 41 to spray the sodium chloride solution onto the ice surface of the wind turbine blades. The sodium chloride solution sprayed onto the ice surface covers the ice surface, lowering the freezing point of the ice covering the wind turbine blade surface, causing the ice cover on the wind turbine blade surface to melt, thereby achieving efficient removal of the ice cover on the wind turbine blades. Therefore, the de-icing device 1 of this embodiment avoids direct contact with the wind turbine blades during the de-icing process, and thus the de-icing device 1 of this embodiment is less likely to damage the blades during de-icing.

[0045] In addition, some sodium chloride solution will flow on the ice surface under the influence of gravity, increasing the contact area between the sodium chloride solution and the ice surface, and making the sodium chloride solution evenly cover the ice surface, further increasing the de-icing efficiency.

[0046] After the wind turbine blades are de-iced, the frame 2 is lowered via the lifting assembly 3.

[0047] After water is injected into the water storage chamber 431 and solid sodium chloride is added to the salt storage chamber 451, the water storage chamber 431 is in a connected state. The water storage chamber 431 supplies water to the salt storage chamber 451, causing the solid sodium chloride in the salt storage chamber 451 to dissolve and form a sodium chloride solution, thereby realizing the preparation of the sodium chloride solution. In other words, the de-icing device 1 of this embodiment can automatically complete the preparation of the sodium chloride solution, avoiding the need for operators to manually prepare the sodium chloride solution, reducing the workload of operators, and further improving the de-icing efficiency.

[0048] The de-icing device of this invention uses a lifting assembly to drive the frame to a position near the wind turbine blades. A spraying assembly then sprays sodium chloride solution from the collection assembly onto the ice surface near the wind turbine blades to lower the melting point of the ice cap, thus melting the ice and removing it. This de-icing device offers high de-icing efficiency and is less likely to damage the wind turbine blades. During the de-icing process, some of the sodium chloride solution flows on the ice surface under gravity, increasing the contact area between the solution and the ice, and ensuring even coverage, further enhancing de-icing efficiency. Furthermore, the device automatically prepares the sodium chloride solution, reducing operator workload and further improving de-icing efficiency.

[0049] like Figure 2 and Figure 3 As shown, in some embodiments, the liquid collection assembly 4 includes at least one water storage bottle 43, a placement box 45, a liquid collection box 42, and a manifold 44. The water storage bottle 43 is provided with a water storage cavity 431, and the bottom of the water storage bottle 43 is provided with a water outlet 432 communicating with the water storage cavity 431; the placement box 45 is provided with a salt storage cavity 451; the liquid collection box 42 is provided with a liquid collection cavity 41; the manifold 44 includes at least one manifold trough 441, which corresponds one-to-one with the water storage bottle 43. The first end of the manifold trough 441 is connected to the water outlet 432 of the corresponding water storage bottle 43, and the second end of the manifold trough 441 is connected to the salt storage cavity 451. The manifold trough 441 is inclined to transport water in the water storage cavity 431 to the salt storage cavity 451.

[0050] Water in the water storage chamber 431 of the water storage bottle 43 flows into the confluence channel 441 of the manifold 44 through the outlet 432. The confluence channel 441 is inclined, and the water in the confluence channel 441 flows into the salt storage chamber 451 under the action of gravity.

[0051] The placement box 45 and the water storage bottle 43 are independent of each other, which facilitates the addition of solid sodium chloride to the salt storage chamber 451 and the replenishment of water to the water storage chamber 431.

[0052] like Figure 3 , Figure 4 and Figure 5As shown, as an example, there are 4 water storage bottles 43 and 4 manifolds 441. The 4 manifolds 441 correspond one-to-one with the 4 water storage bottles 43. The 4 water storage bottles 43 are evenly spaced in the circumferential direction of the placement box 45 so that the frame 2 can maintain balance during flight.

[0053] like Figure 6 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the frame 2 is provided with a sliding groove 22, and a first docking groove 221 and a second docking groove 222 are formed on the inner wall of the sliding groove 22. The first docking groove 221 and the second docking groove 222 are arranged opposite to each other in the vertical direction. A sliding block 437 is provided on the water storage bottle 43. The sliding block 437 is slidably disposed in the sliding groove 22 between a sliding position and a fixed position. The sliding block 437 in the sliding position is separated from the first docking groove 221 and the second docking groove 222, and the sliding block 437 in the fixed position is... In one of the first docking groove 221 and the second docking groove 222, a spring piece 23 is provided in the other of the first docking groove 221 and the second docking groove 222. One end of the spring piece 23 abuts against the inner wall of the corresponding other of the first docking groove 221 and the second docking groove 222, and the other end of the spring piece 23 abuts against the sliding block 437 located in a fixed position. The spring piece 23 is in a compressed state so as to push the sliding block 437 into the corresponding one of the first docking groove 221 and the second docking groove 222 where the sliding block 437 is located.

[0054] When the water storage bottle 43 needs to be disassembled, the sliding block 437 is separated from the first docking groove 221 and the second docking groove 222. That is, the position of the sliding block 437 changes from a fixed position to a sliding position, and the sliding block 437 can slide in the sliding groove 22. The sliding block 437 is slid to one end of the sliding groove 22 so that the sliding block 437 and the sliding groove 22 are separated, thereby realizing the disassembly of the water storage bottle 43 to facilitate the replacement of water in the water storage bottle 43.

[0055] When the water storage bottle 43 needs to be installed, the sliding block 437 is positioned in the sliding groove 22 and either the first docking groove 221 or the second docking groove 222. That is, the position of the sliding block 437 is changed from a sliding position to a fixed position, thereby realizing the installation of the water storage bottle 43.

[0056] Furthermore, in some embodiments, such as Figure 8As shown, a limiting member 24 is connected to one end of the spring piece 23 facing the sliding groove 22. The limiting member 24 is movably positioned relative to the mating groove under the action of the spring piece 23. The end face of the limiting member 24 facing the sliding groove 22 is an inclined surface. The inclined surface is used to abut against the sliding block 437 when the sliding block 437 slides to the corresponding position of the first mating groove 221 and the second mating groove 222, and to generate relative sliding between the two. When the sliding block 437 has not reached the corresponding position of the first mating groove 221 and the second mating groove 222, at least a portion of the limiting member 24 extends into the sliding groove 22 under the elastic force of the spring piece 23. When the sliding block 437 slides along the sliding groove 22 and moves towards the corresponding position of the first mating groove 221 and the second mating groove 222, the sliding block 437 abuts against the inclined surface of the limiting member 24 and slides relative to the inclined surface. During the relative sliding process, the limiting member 24 gradually extends into the corresponding mating groove under the action of the sliding block 437, squeezing the spring piece 23. When the sliding block 437 reaches the corresponding position of the first mating groove 221 and the second mating groove 222, the limiting member 24 pushes the sliding block 437 into the corresponding mating groove under the elastic force of the spring piece 23, so that the sliding block 437 reaches a fixed position. In the fixed position, the limiting member 24 always abuts against the sliding block 437 to make it stable in the fixed position. In other words, the setting of the limiting member 24 facilitates the sliding block 437 to squeeze the spring piece 23. At the same time, the limiting member 24 can increase the elastic deformation of the spring piece 23 by squeezing the spring piece 23, thereby increasing the force of the spring piece 23 on the sliding block 437.

[0057] As an example, such as Figure 6 , Figure 8 , Figure 9 and Figure 10 As shown, each water storage bottle 43 is provided with two sliding blocks 437, and the number of sliding grooves 22 matches the number of sliding blocks 437 and corresponds one-to-one with each sliding block 437. The first docking groove 221 is located above the second docking groove 222, and the spring piece is set in the second docking groove 222.

[0058] When the water storage bottle 43 needs to be installed, the sliding block 437 on the water storage bottle 43 is slid into the corresponding sliding groove 22. The sliding block 437 slides until it contacts the inclined surface of the limiting member 24 and continues to slide, causing the limiting member 24 to press down into the second docking groove 222. At the same time, the limiting member 24 squeezes the spring piece 23. When the sliding block 437 reaches the position corresponding to the first docking groove 221, the sliding block 437 is inserted upward into the first docking groove 221 under the action of the limiting member 24 and fixed in the first docking groove 221, thereby fixing the water storage bottle 43.

[0059] When it is necessary to disassemble the water bottle 43, hold the water bottle 43 and move it downwards. During the downward movement, the sliding blocks 437 on both sides of the water bottle 43 press down on the limiting member 24 and the spring piece 23 until they are disengaged from the first docking groove 221. As the water bottle 43 is slid outwards along the sliding groove 22, the sliding block 437 disengages from the limiting member 24, and the limiting member 24 and the spring piece 23 return to their original positions. Continue to slide the water bottle 43 outwards along the sliding groove 22 until the sliding block 437 disengages from the sliding groove 22, thereby disassembling the water bottle 43.

[0060] like Figure 8 As shown, optionally, a limiting member 24 is provided between the sliding block 437 located in a fixed position and the spring piece 23. The limiting member 24 squeezes the spring piece 23 to increase the elastic deformation of the spring piece 23 and increase the force of the spring piece 23 on the sliding block 437.

[0061] like Figure 3 and Figure 7 As shown, in some embodiments, the water storage bottle 43 includes a sealing plate 433 and a spring 436. The sealing plate 433 is movably disposed in the water storage cavity 431 in the vertical direction between a sealing position and a disengaged position. When the sealing plate 433 is in the sealing position, it seals the water outlet 432. When the sealing plate 433 is in the disengaged position, it separates from the water outlet 432. The spring 436 is located above the sealing plate 433 and abuts against the top of the sealing plate 433. The spring 436 is used to push the sealing plate 433 to the sealing position.

[0062] The manifold 44 includes a connecting pipe 442 that corresponds to and communicates with the first end of the manifold 441. The connecting pipe 442 extends vertically upward and has a water inlet 4421 on its side wall. The top end of the connecting pipe 442 abuts against the sealing plate 433. The manifold 44 is movably arranged vertically so that the sealing plate 433 can be pushed upward to the disengaged position through the connecting pipe 442. In the disengaged position, the water inlet 4421 extends into the water storage chamber 431 to achieve communication between the water storage chamber 431 and the manifold 441. The connecting pipe 442 is sealed to the water storage bottle 43.

[0063] As an example, the sealing plate 433 is in the sealing position to block the outlet 432, causing the manifold 44 to move upward in the vertical direction so that the connecting pipe 442 pushes the sealing plate 433 to the disengaged position. The sealing plate 433 separates from the outlet 432, and the water in the water storage chamber 431 enters the connecting pipe 442 through the outlet 432 and the inlet hole 4421 and flows into the manifold 441, thereby preventing the water in the water storage bottle 43 from spilling out when the water storage bottle 43 is installed while it is storing water.

[0064] As an example, the sealing plate 433 moves from the separated position to the sealing position under the action of the spring 436. When the connecting pipe 442 is separated from the sealing plate 433 or when the connecting pipe 442 and the sealing plate 433 are about to be separated, the sealing plate 433 is in the sealing position to prevent water in the water storage chamber 431 from leaking out of the outlet 432 when the water storage bottle is disassembled.

[0065] like Figure 7 As shown, in some embodiments, the water storage bottle 43 is provided with a drain plate 434 to divide the water storage chamber 431 into a first water storage chamber 4311 and a second water storage chamber 4312. The first water storage chamber 4311 is located above the second water storage chamber 4312. The drain plate 434 is provided with a drain hole 4341 to connect the first water storage chamber 4311 and the second water storage chamber 4312. That is, water in the first water storage chamber 4311 can enter the second water storage chamber 4312, and water in the second water storage chamber 4312 can enter the first water storage chamber 4311. The outlet 432 is located at the bottom of the second water storage chamber 4312, the sealing plate 433 is located inside the second water storage chamber 4312, the spring 436 is abutted between the sealing plate 433 and the leaking plate 434, the sealing plate 433 is provided with a guide rod 435 extending in the vertical direction, the leaking plate 434 is provided with a guide hole 4342, and the guide rod 435 is movably disposed in the guide hole 4342.

[0066] The guide rod 435 and the guide hole 4342 cooperate to guide the sealing plate 433. The drain plate 434 abuts against one end of the spring 436 so that the spring 436 pushes the sealing plate 433 to the sealing position.

[0067] like Figure 4 and Figure 5 As shown, in some embodiments, the de-icing device 1 further includes a positioning rod 47 and a positioning insert plate 48. The positioning rod 47 extends vertically, and its lower end is connected to the manifold 44. The frame 2 is provided with a positioning hole 21. The positioning rod 47 is movably disposed in the positioning hole 21 in the vertical direction. The outer peripheral surface of the positioning rod 47 is provided with a positioning slot (not shown in the figure). The positioning insert plate 48 moves between the insertion position of extending into the positioning slot and the separation position of disengaging from the positioning slot. When the sealing plate 433 reaches the disengagement position, the positioning insert plate 48 is positioned in the insertion position to fix the positioning rod 47 and the manifold 44 in the vertical direction. When the positioning insert plate 48 is in the separation position, the sealing plate 433 moves to the sealing position under the action of the spring 436, while the manifold 44 moves downward.

[0068] The manifold 44 is moved upward so that the sealing plate 433 is in the sealing position. The positioning plate 48 is inserted into the positioning slot of the positioning rod 47 to position the positioning rod 47. The lower end of the positioning rod 47 is connected to the manifold 44, thereby fixing the manifold 44 and then fixing the sealing plate 433 so that the sealing plate 433 is in the sealing position.

[0069] Positioning plate 48 is in the separated position, positioning slot is separated from positioning plate 48, and positioning rod 47 and manifold 33 move downward under the action of spring 436. When connecting pipe 442 is separated from sealing plate 433 or when connecting pipe 442 and sealing plate 433 are about to be separated, sealing plate 433 is in the sealing position.

[0070] In some specific embodiments, when installing multiple water storage bottles 43, the sliding blocks 437 on the multiple water storage bottles 43 are fixed in a fixed position, and the manifold 44 moves upward so that each connecting pipe 442 pushes the cooperating sealing plate 433 to the disengaged position. This allows the manifold 44 to control the multiple sealing plates 433 to be in the disengaged position, thereby reducing the installation time of the water storage bottles 43 and improving the installation efficiency. When disassembling multiple water storage bottles 43, the manifold 44 moves downward so that each connecting pipe 442 is disengaged from the sealing plate 433 or is in a state of imminent disengagement. This ensures that each sealing plate is in the sealing position, thereby allowing the manifold 44 to control the multiple sealing plates 433 to be in the sealing position, thereby reducing the disassembly time of the water storage bottles 43 and improving the disassembly efficiency.

[0071] like Figure 4 and Figure 5 As shown, in some embodiments, multiple positioning rods 47 and positioning inserts 48 are provided, with multiple positioning inserts 48 and multiple positioning rods 47 corresponding one to one. The de-icing device 1 also includes a rotating rod 481, which is rotatably mounted on the frame 2. The rotating rod 481 is connected to each positioning insert 48 to drive each positioning insert 48 to move between the insertion position and the disengagement position.

[0072] The position of multiple positioning plates 48 is controlled by the rotating rod 481.

[0073] like Figure 4 and Figure 5 As shown, optionally, four positioning rods 47 are provided, each positioning rod 47 being evenly arranged along the circumferential direction of the placement box 45 to ensure the stability of the frame 2 during flight.

[0074] like Figure 4 and Figure 5As shown, in some embodiments, the de-icing device 1 also includes a torsion spring 49, one end of which is connected to the frame 2 and the other end of which is connected to the rotating rod 481. The torsion spring 49 pushes the positioning insert plate 48 to the insertion position.

[0075] When the sealing plate 433 is in the disengaged position, the positioning insert plate 48 can automatically be in the insertion position and be inserted into the positioning slot of the positioning rod 47 under the action of the torsion spring 49.

[0076] During the flight of the frame 2, unexpected vibrations may occur, causing the positioning rod 47 to tend to rotate. The torsion spring 49 acts on the positioning rod 47 to counteract the rotational tendency of the positioning rod 47.

[0077] In some embodiments, the second end of the manifold 441 is connected to the bottom opening of the salt storage chamber 451. A screen 452 is provided at the bottom opening of the salt storage chamber 451 to prevent undissolved solid sodium chloride from leaking out, thus preventing undissolved solid sodium chloride from entering the manifold 441 and clogging it. The liquid collection chamber 41 is located below the salt storage chamber 451 and is opposite to the bottom opening of the salt storage chamber 451 so that the sodium chloride solution can flow into the liquid collection chamber 41, so that the water in the water storage chamber 431 enters the salt storage chamber 451 to form a sodium chloride solution and then flows into the liquid collection chamber 41.

[0078] like Figure 3 As shown, optionally, the liquid collection chamber 41 is located below the salt storage chamber 451, the bottom opening of the salt storage chamber 451 is connected to the upper end of the liquid collection chamber 41, the second end of the confluence channel 441 is connected to the liquid collection chamber 41, the water in the outlet chamber 431 flows into the liquid collection chamber 41, and the water in the liquid collection chamber 41 enters the salt storage chamber 451 from the bottom opening of the salt storage chamber 451 to dissolve the solid sodium chloride in the salt storage chamber 451.

[0079] like Figure 3 As shown, optionally, the salt storage chamber 451 is inclined downwards.

[0080] Water entering the salt storage chamber 451 flows downwards out of the salt storage chamber 451, preventing water accumulation inside the salt storage chamber 451.

[0081] Because the salt storage chamber 451 is tilted downwards, the solid sodium chloride is located at the bottom opening of the salt storage chamber 451 under the action of gravity, so that even if the water level in the salt storage chamber 451 is too low, the water in the salt storage chamber 451 can still dissolve the solid sodium chloride.

[0082] There are many parts near the busbar 44, making it difficult for operators to control the movement of the busbar 44.

[0083] Therefore, such as Figure 2 and Figure 6As shown, in some embodiments, the de-icing device 1 further includes a drive rod 410, which is provided with a drive groove 4101. A slide rod 443 is provided on the manifold 44, which is slidably inserted through the drive groove 4101. The drive rod 410 is swayably mounted on the frame 2 to drive the manifold 44 to move up and down. The position of the manifold 44 is controlled by swinging the drive rod 410, which reduces the difficulty of controlling the movement of the manifold 44.

[0084] In some embodiments, the lifting assembly 3 includes a motor 31 and a fan blade 32. The motor 31 is connected to the frame 2, and the motor 31 is connected to the fan blade 32 to drive the fan blade 32 to rotate in order to drive the frame 2 to take off and land. The de-icing device 1 also includes a stirring rod 46. The stirring part 461 of the stirring rod 46 extends into the liquid collection chamber 41. The motor 31 is connected to the stirring rod 46 to drive the stirring rod 46 to rotate in order to stir the sodium chloride solution in the liquid collection chamber 41, so that the solid sodium chloride in the liquid collection chamber 41 is fully dissolved.

[0085] As an example, a synchronous belt assembly 6 is provided between the stirring rod 46 and a motor 31. One end of the synchronous belt assembly 6 is connected to the motor 31 and the other end is connected to the stirring rod 46 to realize power transmission between the motor 31 and the stirring rod 46.

[0086] like Figure 5 As shown, optionally, the synchronous belt assembly 6 includes a first pulley 61, a second pulley 62, and a belt 63. The first pulley 61 is connected to the stirring rod 46, the second pulley 62 is connected to a motor 31, and the belt 63 is sleeved on the first pulley 61 and the second pulley 62 to realize power transmission between the motor 31 and the stirring rod 46.

[0087] like Figure 5 As shown, optionally, the timing belt assembly 6 further includes a protective cover 64, which covers the first pulley 61, the second pulley 62 and the belt 63 to protect the first pulley 61, the second pulley 62 and the belt 63.

[0088] In some embodiments, the spray assembly 5 includes a nozzle 51 and a spray hose 52, one end of which is connected to the liquid collection chamber 41 and the other end of which is connected to the nozzle 51 to transmit sodium chloride solution to the nozzle 51 for spraying the ice surface.
