Description

Technical Field

[0001] This invention relates to the technical field of wind power generation equipment, and in particular to a method for sun-directed de-icing of wind turbine blades in high-altitude areas. Background Technology

[0002] With the development of wind power resources in my country, many wind farms are located in areas prone to freezing, and blade icing has a significant impact on wind power applications. In particular, blade icing increases mechanical imbalance loads, leading to large vibrations and even resonance, which may damage the blades and force the wind farm to shut down.

[0003] To eliminate the effects of freezing, conventional methods mainly focus on two aspects: preventing icing and de-icing after icing has occurred. Preventing icing can be achieved by spraying hydrophobic materials onto the blades. Once icing has formed, de-icing can be carried out using chemical, mechanical, or heating methods.

[0004] However, a single anti-icing solution for the blade surface cannot completely prevent icing formation. Once icing occurs under rapid temperature drops, the anti-icing coating cannot quickly remove the icing after it has formed. De-icing blades with mechanical structures cannot rationally activate de-icing equipment based on the blade's operating status and the icing condition on its surface, thus affecting the normal operation of the wind turbine. Furthermore, the presence of numerous drive and electric heating devices on the blade surface reduces the energy conversion rate between wind and electricity in the wind turbine. Summary of the Invention

[0005] In view of the problems existing in the above-mentioned methods for sun-directed de-icing of high-altitude wind turbines and wind turbine blades, a first embodiment of the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a high-altitude wind turbine that solves the technical problem that ice accumulation on the surface of wind turbine blades increases mechanical imbalance load, leading to significant vibration, or even resonance, potentially damaging the blades and forcing the turbine to shut down.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including an installation unit, a heating unit, and a blade unit.

[0008] The installation unit includes a base and a wind energy conversion component disposed on the base; the heating unit includes a heating seat assembly disposed on the wind energy conversion component and a heating tube assembly disposed on the heating seat assembly; and the blade unit includes a blade assembly disposed on the heating seat assembly and having the heating tube assembly attached to its surface, a deformation component disposed on the blade assembly, and a connecting component disposed between the blade assembly and the deformation component.

[0009] In a preferred embodiment of the high-altitude wind turbine of the present invention, the wind energy conversion component includes a conversion chamber disposed on the base, a generator disposed on the conversion chamber, and a rotating seat disposed on the generator; wherein the generator is provided with a rotating shaft connected to the rotating seat.

[0011] As a preferred embodiment of the high-altitude wind turbine of the present invention, the blade assembly includes a blade seat disposed on the wind energy conversion component and a guide seat disposed on the blade seat, wherein the guide seat is provided with a deformation groove corresponding to the deformation component and a connecting groove for the connecting component; the heating pipe assembly includes a main heating pipe disposed on the blade seat, a first connecting heating pipe disposed on the main heating pipe, a second connecting heating pipe disposed on the main heating pipe, a reinforcing heating pipe disposed on the first connecting heating pipe and the second connecting heating pipe, and a sealing heating pipe disposed at the end of the first connecting heating pipe and the second connecting heating pipe away from the blade seat.

[0012] As a preferred embodiment of the high-altitude wind turbine of the present invention, the deformation component includes a deformation base disposed on the air guide seat, a main deformation part disposed on the deformation base, and a secondary deformation part disposed on the deformation base in conjunction with the main deformation part.

[0013] In a preferred embodiment of the high-altitude wind turbine of the present invention, the total deformation section includes a total deformation blade and a secondary deformation blade connecting block disposed on the total deformation blade; wherein, the total deformation blade is provided with a limiting inclined surface; the secondary deformation section is provided with a total deformation blade connecting groove corresponding to the secondary deformation blade connecting block and a base connecting groove corresponding to the deformation base; the deformation base is provided with a total deformation blade slot corresponding to the total deformation blade, a sliding groove corresponding to the secondary deformation section, a through groove for the connecting component, and a positioning inclined surface corresponding to the limiting inclined surface; wherein, the sliding groove is provided with an anti-fall-off plate corresponding to the base connecting groove.

[0014] As a preferred embodiment of the high-altitude wind turbine of the present invention, the connecting assembly includes a connecting base disposed on the connecting groove, a mounting seat disposed on the through groove, and a connecting member disposed on the mounting seat, with one end disposed on the connecting base and the other end disposed on the total deformation blade.

[0015] As a preferred embodiment of the high-altitude wind turbine of the present invention, the connecting member includes a universal connecting seat one disposed on the total deformation blade, a telescopic rod disposed on the universal connecting seat one, and a universal connecting seat two disposed on the telescopic rod and located on the connecting base; the telescopic rod includes a sliding rod, a sleeve rod slidably sleeved on the sliding rod, and a spring disposed between the sliding rod and the sleeve rod.

[0016] The beneficial effects of the first embodiment of the present invention are as follows: by setting a heating tube assembly on the surface of the blade unit, the heat generated by the rotating shaft in the wind energy conversion component during operation is used to heat the heating tube assembly, thereby heating the surface of the blade. At the same time, the deformation unit drives some blades on the surface of the blade to produce controllable deformation during rotation, thereby promoting de-icing and avoiding unbalanced mechanical loads after the blade surface is covered with ice.

[0017] In view of the problems existing in the above-mentioned methods for sun-facing de-icing of wind turbine blades, a second embodiment of the present invention is proposed.

[0018] Therefore, the purpose of this invention is to provide a method for de-icing wind turbine blades by facing the sun, which solves the technical problem that anti-icing coating solutions cannot quickly remove icing after it has already occurred.

[0019] To solve the above-mentioned technical problems, the present invention provides the following technical solution: applied to the high-altitude wind turbine according to any one of the claims, the method includes spraying a black hydrophobic material on the icing-prone areas of the blade unit.

[0020] The beneficial effects of the second embodiment of the present invention are as follows: This method can combine the mechanical structure of the blade unit to guide the heat generated by the wind power generation component to the blade unit, thereby heating the surface of the blade unit and achieving the effect of preventing icing and rapid de-icing on the surface of the blade unit. This avoids setting up more drive equipment and electric heating equipment, which would reduce the energy conversion rate between wind power and electrical energy of the wind turbine.

[0021] In view of the problems existing in the above-mentioned methods for sun-facing de-icing of wind turbine blades, a third embodiment of the present invention is proposed.

[0022] Therefore, the purpose of this invention is to provide a method for de-icing wind turbine blades in a light-oriented manner, which solves the technical problem that existing de-icing blades with mechanical structures cannot rationally start the de-icing equipment based on the impact of the blade's working state and the ice cover on the blade surface on the normal operation of the wind turbine.

[0023] To solve the above-mentioned technical problems, the present invention provides the following technical solution: applied to the high-altitude wind turbine according to any one of the claims, the method includes: setting a photosensitive yaw control system on the surface of the blade unit, the photosensitive yaw control system including a wind-following unit and a light-following unit; when the photosensitive yaw control system is controlled by the wind-following unit, it is in working mode; when the photosensitive yaw control system is controlled by the light-following unit, it is in ice-melting mode.

[0024] Under normal operating conditions, the wind turbine operates in the following mode: During a de-icing cycle, after the blade unit is iced and shut down, the photosensitive yaw control system is controlled by the beam tracking unit and switches to de-icing mode. The de-icing mode operating time of the beam tracking unit is adjusted according to the actual wind farm conditions. When the wind turbine's operating wind speed is greater than the starting wind speed, the photosensitive yaw control system switches to being controlled by the beam tracking unit, automatically starts the wind turbine, and activates the operating mode. If the wind turbine's operating wind speed does not meet the condition of being greater than the starting wind speed, the de-icing mode controlled by the beam tracking unit will continue to be maintained.

[0025] If the wind turbine is still determined to be in an ice-covered shutdown state, it will continue to switch to the mode controlled by the light-tracking unit in the photosensitive yaw control system and enter the next de-icing cycle, maintaining the de-icing mode continuously.

[0026] The beneficial effects of the third embodiment of the present invention are as follows: This method determines the icing condition on the surface of the wind turbine blade unit by measuring the relationship between the operating wind speed and the starting wind speed of the wind turbine, and then performs de-icing work according to the actual situation of the wind turbine, which effectively improves the working efficiency of wind turbine anti-icing and de-icing.

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0039] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth.

[0040] Example 1, referring to Figure 1 The first embodiment of the present invention provides a high-altitude fan, which includes an installation unit 100, a heating unit 200, and a blade unit 300.

[0041] The installation unit 100 includes a base 101 and a wind energy conversion component 102 disposed on the base 101; the heating unit 200 includes a heating seat assembly 201 disposed on the wind energy conversion component 102 and a heating pipe assembly 202 disposed on the heating seat assembly 201; and the blade unit 300 includes a blade assembly 301 disposed on the heating seat assembly 201 and having the heating pipe assembly 202 attached to its surface, a deformation assembly 302 disposed on the blade assembly 301, and a connecting assembly 303 disposed between the blade assembly 301 and the deformation assembly 302.

[0042] During operation, the wind turbine uses wind energy to drive the blade unit 300, which in turn drives the wind energy conversion component 102 to rotate on the base 101, thereby converting wind energy into electrical energy for subsequent output. When the wind turbine is in a low-temperature environment where icing is possible, the heating pipe assembly 202 can conduct the heat generated by the wind energy conversion component 102 during operation to the blade assembly 300, thus reusing the heat inside the wind turbine. This effectively prevents icing on the blade surface in low-temperature environments and, if icing has already occurred, can promote melting and remove the icing. Simultaneously, the deformation component 302 on the blade unit 300 can provide controllable deformation between the deformation component and the blade assembly 301 via the connecting component 303 during wind turbine operation, thereby accelerating the melting and shedding of icing on the surface of the blade unit 300.

[0043] Furthermore, the wind energy conversion component 102 includes a conversion chamber 102a disposed on the base 101, a generator 102b disposed on the conversion chamber 102a, and a rotating seat 102c disposed on the generator 102b; wherein, the generator 102b is provided with a rotating shaft 102b-1 connected to the rotating seat 102c.

[0044] Furthermore, the heating seat assembly 201 includes a heat-conducting seat 201a disposed on the rotating shaft 102b-1, a heat-conducting pipe 201b disposed on the heat-conducting seat 201a, and a heat-conducting wire 201c disposed within the heat-conducting pipe 201b and the heating pipe assembly 202. The heat-conducting seat 201a can guide the heat generated by the rotating shaft 201b-1 to the blade unit 300, and conduct it to the entire surface of the blade unit 300 through the heat-conducting pipe 201b and the heat-conducting wire 201c, while preventing the heat-conducting wire 201c from affecting the normal deformation of the deformation assembly 302.

[0045] Furthermore, the blade assembly 301 includes a blade holder 301a disposed on the wind energy conversion assembly 102, and a wind guide seat 301b disposed on the blade holder 301a. The wind guide seat 301b has a deformation groove 301b-1 corresponding to the deformation assembly 302, and a connecting groove 301b-2 for the connecting assembly 303. The deformation groove 301b-1 corresponding to the deformation assembly 302 is provided on the wind guide seat 301b, facilitating the installation of the deformation assembly 302 on the wind guide seat 301b.

[0046] The heating tube assembly 202 includes a main heating tube 202a disposed on the blade seat 301a, a connecting heating tube 1 202b disposed on the main heating tube 202a, a connecting heating tube 202c disposed on the main heating tube 202a, a reinforcing heating tube 202d disposed on the connecting heating tube 1 202b and the connecting heating tube 202c, and a sealing heating tube 202e disposed at the end of the connecting heating tube 1 202b and the connecting heating tube 202c away from the blade seat 301a, thereby facilitating the uniform guidance of the heat transmitted from the main heating tube 202a to the blade unit 300.

[0047] Furthermore, the deformation component 302 includes a deformation base 302c disposed on the air guide seat 301b, a main deformation part 302a disposed on the deformation base 302c, and a secondary deformation part 302b disposed on the deformation base 302c in conjunction with the main deformation part 302a.

[0048] During use, the deformation base 302c deforms relative to the air guide 301b, and the total deformation part 302a deforms relative to the air guide 301b under the drive of the deformation base 302c. At the same time, the total deformation part 302a drives the secondary deformation part 302b to deform relative to the blade edge 301b, so that the surface of the overall blade unit 300 can undergo controllable slight deformation, thereby accelerating the melting speed and the ice block shedding speed.

[0049] Example 2, refer to Figure 1This is the second embodiment of the present invention, which differs from the first embodiment in that: the total deformation part 302a includes a total deformation blade 302a-1 and a secondary deformation blade connecting block 302a-2 disposed on the total deformation blade 302a-1; wherein, the total deformation blade 302a-1 is provided with a limiting inclined surface 302a-11; the secondary deformation part 302b is provided with a total deformation blade connecting groove 302b-2 corresponding to the secondary deformation blade connecting block 302a-2 and a base connecting groove 302b-1 corresponding to the deformation base 302c; the deformation base 302c is provided with a total deformation blade slot 302c-1 corresponding to the total deformation blade 302a-1, a sliding groove 302c-2 corresponding to the secondary deformation part 302b, a through groove 302c-3 provided with a connecting component 303, and a positioning inclined surface 302c-4 corresponding to the limiting inclined surface 302a-11. Setting the positioning slope 302c-4 facilitates the overall deformation of the blade 302a-1.

[0050] During operation, the wind turbine uses wind energy to drive the blade unit 300, which in turn drives the wind energy conversion component 102 to rotate on the base 101, thereby converting wind energy into electrical energy for subsequent output. When the wind turbine is in a low-temperature environment where icing is possible, the heating pipe assembly 202 can conduct the heat generated by the wind energy conversion component 102 during operation to the blade assembly 300, thus reusing the internal heat of the wind turbine. This effectively prevents icing on the blade surface in low-temperature environments and, if icing has already occurred, can promote melting and remove the icing. Simultaneously, the deformation component 302 installed on the blade unit 300 can provide controllable deformation between the deformation component and the blade assembly 301 via the connecting component 303 during wind turbine operation, thereby accelerating the melting and shedding of icing on the surface of the blade unit 300.

[0051] Preferably, the slide groove 302c-2 is provided with an anti-detachment plate 3022c-11 corresponding to the base connection groove 302b-1, thereby preventing the deformation base 302c from falling off the total deformation blade 302a-1. This facilitates the total deformation blade 302a-1 to drive the secondary deformation part 302b to deform synchronously when it undergoes slight deformation, thereby increasing the area on the surface of the blade unit 300 that can synchronously eliminate melting ice when the total deformation blade 302a-1 deforms.

[0052] Furthermore, the connecting assembly 303 includes a connecting base 303a disposed on the connecting groove 301b-2, a mounting seat 303b disposed on the through groove 302c-3, and a connector 303c disposed on the mounting seat 303b, with one end attached to the connecting base 303a and the other end attached to the overall deformation blade 302a-1. By providing the connecting assembly 303, the overall deformation blade 302a-1 can undergo slight, controllable deformation at the blade seat 301a under the connection control of the connecting assembly 303, thereby accelerating the melting of ice on the surface of the blade unit 300. The connecting base 303a facilitates the placement of the connector 303c on the air guide seat 301b, thus ensuring the integrity of the blade unit 300 and preventing the deformation assembly 302 from affecting the overall rotational stability of the blade unit 300 and the mechanical balance load of the blade.

[0053] Furthermore, the connector 303c includes a universal joint seat 303c-1 disposed on the overall deformation blade 302a-1, a telescopic rod 303c-2 disposed on the universal joint seat 303c-1, and a second universal joint seat 303c-3 disposed on the telescopic rod 303c-2 and located on the connecting base 303a. By setting the connector 303c, the overall deformation blade 302a-1 achieves slightly controllable deformation on the blade seat 301a, thereby accelerating the melting of ice on the surface of the blade unit 300.

[0054] Preferably, the telescopic rod 303c-2 includes a sliding rod 303c-21, a sleeve rod 303c-22 slidably sleeved on the sliding rod 303c-21, and a spring 303c-23 disposed between the sliding rod 303c-21 and the sleeve rod 303c-22. By providing the spring 303c-23, the sliding rod 303c-21 and the sleeve rod 303c-22 slidably sleeved on the sliding rod 303c-21 are elastically connected by the spring 303c-23, thereby enabling... The universal joint 303c-1 and universal joint 303c-3 at both ends of the telescopic rod 303c-2 are elastically connected, thereby making the connecting base 303a on the universal joint 303c-3 and the total deformation blade 302a-1 on the universal joint 303c-1 elastically connected. This enables the total deformation blade 302a-1 to undergo slight and controllable deformation on the blade seat 301a, thereby accelerating the melting of ice on the surface of the blade unit 300.

[0055] Preferably, a limiting block B is provided on the slide rod 303c-21, and a limiting groove C is provided on the sleeve rod 303c-22 for the limiting block B to slide. The limiting block B can only slide inside the limiting groove C, thus preventing the slide rod 303c-21 from falling off the sleeve rod 303c-22 and achieving the effect of limiting the slide rod 303c-21.

[0056] The remaining structure is the same as that in Example 1.

[0057] Example 3 is the third embodiment of the present invention. Based on the wind turbine provided in Examples 1 and 2, this embodiment provides a method for de-icing wind turbine blades towards the light. The method includes spraying a black hydrophobic material onto the key icing areas of the blade unit 300.

[0058] The de-icing principle of this method is as follows: anything that appears white reflects all wavelengths of light, resulting in extremely low heat absorption efficiency. Black, on the other hand, is the color with the lowest reflectivity, absorbing all light and therefore exhibiting the highest heat absorption efficiency. By utilizing the coating on the blade unit surface to concentrate the energy contained in sunlight, and fully leveraging the lowest reflectivity of black, the method improves the heat absorption and melting efficiency of wind turbine blades after icing, increasing the visibility of the blades, enhancing aerial visibility, and preventing bird strikes. Simultaneously, based on winter wind direction characteristics and the actual conditions of the production site, it fully utilizes the powerful solar energy for rapid de-icing. Since it does not require a separate de-icing heat source and the system is simple, it features low investment and high returns, making it highly valuable for application and promotion in the wind power industry.

[0059] Preferably, an anti-adhesion coating can also be provided on the surface of the blade unit 300. A special anti-adhesion coating can improve the anti-adhesion properties of the blade surface. These coatings typically have low surface energy and anti-adhesion properties, making it difficult for ice to adhere and easy to remove. Examples include polytetrafluoroethylene (PTFE) coatings.

[0060] Preferably, an anti-icing fluid coating can also be applied to the surface of the blade unit 300. Applying a special anti-icing fluid agent can reduce the formation and adhesion of ice. These liquids can lower the freezing point temperature of the blade surface, prevent ice formation, or make ice easier to detach, which helps to accelerate the de-icing speed of the blade unit.

[0061] Example 4 is the fourth embodiment of the present invention. Based on the wind turbine provided in Examples 1 and 2, this embodiment provides a method for de-icing wind turbine blades towards sunlight. The method includes setting a photosensitive yaw control system on the surface of the blade unit 300. The photosensitive yaw control system includes a wind-following unit and a light-following unit. When the photosensitive yaw control system is controlled by the wind-following unit, it is in working mode. When the photosensitive yaw control system is controlled by the light-following unit, it is in de-icing mode.

[0062] Under normal operating conditions, the wind turbine operates in the following mode: During a de-icing cycle, after the blade unit 300 is iced and shut down, the photosensitive yaw control system is controlled by the beam tracking unit and switches to de-icing mode. The de-icing mode operating time of the beam tracking unit is adjusted according to the actual wind farm conditions. When the wind turbine's operating wind speed is greater than the starting wind speed, the photosensitive yaw control system switches to being controlled by the beam tracking unit, automatically starts the wind turbine, and activates the operating mode. If the wind turbine's operating wind speed does not meet the condition of being greater than the starting wind speed, the de-icing mode controlled by the beam tracking unit continues to be maintained.

[0063] If the wind turbine is still determined to be in an ice-covered shutdown state, it will continue to switch to the mode controlled by the light-tracking unit in the photosensitive yaw control system and enter the next de-icing cycle, maintaining the de-icing mode continuously.

[0064] Unless there's a yaw system malfunction or tower base shutdown, wind turbines will remain yawed towards the wind after shutdown, awaiting restart. Normally, wind turbines operate in wind-following mode, meaning the turbine's automatic yaw system yawing according to wind direction. However, wind turbines often experience icing in winter, when northerly winds are more common than the prevailing wind direction. Continuing to follow the wind after the turbine blades are iced hinders the natural melting of the ice. Therefore, allowing the icy blades to face the sun is more conducive to melting and removing the ice. Thus, the control mechanism after a wind turbine shutdown due to icing needs to be changed from "wind-following" to "solar-following."

[0065] The aforementioned light-tracking operation of the photosensitive yaw control system can be achieved by installing a photoresistor on the blade unit 300. The photoresistor and the offset motor relay that drives the rotation of the top rotating base of the wind turbine form a light-tracking circuit. When sunlight shines on the photoresistor, its resistance increases, and the current decreases, causing the current in the circuit containing the photoresistor to be cut off. This leads to the relay in the same circuit releasing and disconnecting, allowing the wind turbine to stop yaw and operate normally. When the sunlight moves away and the photoresistor is no longer illuminated, its resistance decreases, the current in the circuit containing the photoresistor increases, and the relay in the same circuit reactivates, driving the offset motor to continue yaw and achieve light tracking.

6. A method for sun-directed de-icing of wind turbine blades, characterized in that: The method is applied to the high-altitude wind turbine according to any one of claims 1-4, comprising: setting a photosensitive yaw control system on the surface of the blade unit (300), the photosensitive yaw control system including a wind-following unit and a light-following unit; when the photosensitive yaw control system is controlled by the wind-following unit, it is in working mode; when the photosensitive yaw control system is controlled by the light-following unit, it is in de-icing mode. Under normal operating conditions, the wind turbine operates in the following mode: During a de-icing cycle, after the blade unit (300) is iced and shut down, the photosensitive yaw control system is controlled by the tracking unit and switches to de-icing mode. The working time of the tracking unit in de-icing mode is adjusted according to the actual wind farm conditions. When the wind turbine's operating wind speed is greater than the starting wind speed, the photosensitive yaw control system switches to being controlled by the tracking unit, automatically starts the wind turbine, and opens the operating mode. If the wind turbine's operating wind speed does not meet the condition of being greater than the starting wind speed, the photosensitive yaw control system continues to be controlled by the tracking unit in de-icing mode. If the wind turbine is still determined to be in an ice-covered shutdown state, it will continue to switch to the mode controlled by the light-tracking unit in the photosensitive yaw control system and enter the next de-icing cycle, maintaining the de-icing mode continuously.
