In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details.

[0022] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electrical energy. The main function of wind turbine blades is to capture wind energy and convert it into mechanical energy, which is then converted into electrical energy through generators.

[0023] During the production and maintenance of wind turbine blades, local positions of wind turbine blades are often heated. For example, during the production of wind turbine blades, local positions of wind turbine blades may need to be heated to ensure that the adhesive is completely cured and meets the corresponding technical requirements.

[0024] In the related art, workers locally heat the wind turbine blades by blowing hot air with a hot air gun. The above heating method is not only time-consuming and labor-intensive, but also has low heating efficiency.

[0025] In view of this, first of all, please refer to Figures 1 to 3 , an embodiment of the present application provides a heating device, which is used for locally heating a blade. The heating device includes a base 10, a heating component 30, and a connecting component 20 connected between the base 10 and the heating component 30. The base 10 includes a first surface M1 and a second surface M2 that are arranged opposite to each other in a first direction X, and the heating component 30 is arranged on the second surface M2 and heats the blade. The base 10 is detachably connected to the blade through the first surface M1, the area of ​​the first surface M1 is smaller than the area of ​​the blade, and the projection size of the connecting component 20 in the first direction X is adjustable to adjust the distance between the heating component 30 and the base 10.

[0026] The heating device provided in the embodiment of the present application is used for local heating of blades, and the blades refer to wind turbine blades, which are used in wind turbines. When a wind turbine is operating in a cold climate, severe icing may occur on the surface of the blades. Icing will change the aerodynamic shape of the blades, seriously affect the aerodynamic efficiency of the blades, reduce the power generation efficiency of the wind turbine, and increase the load on the wind turbine and the blades. In order to solve the problem of icing on the blade surface, local heating is required to quickly heat and increase the surface temperature of the blades, and stably and reliably achieve rapid ice melting and de-icing of the blades. Alternatively, when the blades are damaged or need to be repaired, local heating can promote the solidification of the repair material and speed up the repair process of the blades.

[0027] Specifically, the heating device includes a base 10, a heating assembly 30, and a connecting assembly 20 connected between the base 10 and the heating assembly 30. The base 10 is configured to be connected to the blade, and the heating assembly 30 is configured to heat the blade. It can be understood that when the heating device is required to heat the blade, the base 10 is fixed relative to the blade, and the heating assembly 30 is adjusted to heat a specific area.

[0028] The base 10 includes a first surface M1 and a second surface M2 that are oppositely arranged in the first direction X. The base 10 is detachably connected to the blade via the first surface M1, and the heating component 30 is connected to the second surface M2 of the base 10 via the connecting component 20. That is, when the base 10 is connected to the blade, the first surface M1 is in contact with the blade, and the second surface M2 is a side away from the blade. The base 10 has a certain operating space on one side of the second surface M2 to facilitate the adjustment of the connecting component 20.

[0029] When the base 10 is connected to the blade, since the area of ​​the first surface M1 is smaller than the area of ​​the blade, the base 10 only covers a portion of the blade and does not affect the heating of the specific area by the heating component 30. In other words, the blade includes at least a first area and a second area, the base 10 is connected to the first area, and the heating component 30 can heat the second area by adjusting the connection component 20.

[0030] The first area is not a fixed position on the blade, but an upper area where the base 10 is connected to the blade. When the position where the base 10 is connected to the blade changes, the first area also changes accordingly. The second area is also not a fixed position on the blade, but an area on the blade that needs to be locally heated. When the position of the area on the blade that needs to be locally heated changes, the position of the second area also changes. Furthermore, after the base 10 is connected to the blade, the heating component 30 can be adjusted to locally heat different areas. In other words, the first area may be surrounded by multiple second areas. Therefore, the first area and the second area do not have specific limitations and are only used to illustrate the area where the base 10 is connected to the blade and the area where the heating component 30 heats the blade.

[0031] The planes formed by the first area and the second area intersect with the first direction X. When the projection size of the connecting assembly 20 in the first direction X is changed, the distance between the first area and the second area can be changed. After the base 10 is fixed relative to the blade in the first area, the second area at different positions can be heated by adjusting the projection size of the connecting assembly 20 in the first direction X.

[0032] Optionally, the connection component 20 can be configured in the form of multiple parts that are slidably plugged into each other, and the extension size of the connection component 20 is related to the plug-in overlap size between the multiple parts. When the plug-in overlap size between the multiple parts becomes smaller, the overall extension size of the connection component 20 becomes larger, and the heating component 30 can heat a farther location.

[0033] In summary, in the embodiment of the present application, the heating device includes a base 10 that can be connected to the blade, a heating component 30 disposed on the base 10 and used to locally heat the blade, and a connecting component 20 connected between the base 10 and the heating component 30. When the heating device is required to locally heat the blade, the base 10 is connected to the blade through the first surface M1. Since the area of ​​the first surface M1 is smaller than the area of ​​the blade, the base 10 only covers a part of the area on the blade and does not affect the heating of the specific area by the heating component 30. When the heating device is not required to locally heat the blade, the base 10 is separated from the blade to separate the entire heating device from the blade. Through the detachable connection between the base 10 and the blade, the base 10 can be conveniently connected to different positions on the blade so that the heating component 30 can heat different areas on the blade. At the same time, the projection size of the connecting component 20 in the first direction X can be adjusted. When the base 10 is fixed relative to the blade, the projection size of the connecting component 20 in the first direction X can be adjusted to achieve heating of different positions on the blade.

[0034] In some embodiments, the first surface M1 is recessed inward to form an adsorption groove 11. The heating device further includes a first control component 40 connected to the second surface M2, the first control component 40 includes a negative pressure member connected to the adsorption groove 11, and the negative pressure member is configured to suck the air in the adsorption groove 11 so that the base 10 is adsorbed on the blade.

[0035] The base 10 and the blades are connected by means of negative pressure adsorption, which can ensure the connection strength between the base 10 and the blades on one hand, and can also conveniently connect or disconnect the base 10 and the blades; on the other hand, in view of the smoothness requirements of the blade surface and the material characteristics of the blades, the connection method of negative pressure adsorption can reduce the impact of the base 10 connection on the blade surface. At the same time, after the base 10 is connected to the blade, the cavity structure inside the blade and the deformation degree of the blade material can ensure good stability between the base 10 and the blade.

[0036] Specifically, the first surface M1 is recessed inward to form an adsorption groove 11, and the first control component 40 includes a negative pressure piece connected to the adsorption groove 11, and the negative pressure piece can suck the air of the adsorption groove 11 so that the base 10 is adsorbed on the blade. Exemplarily, the negative pressure piece can be set as a vacuum pump. During the connection process between the base 10 and the blade, the blade surface and the first surface M1 of the base 10 are wiped clean, the base 10 is placed at the connection position of the blade, and the air inside the adsorption groove 11 can be vacuumed by turning on the switch of the vacuum pump. When the vacuum value inside the adsorption groove 11 reaches a preset value, the vacuuming can be stopped. During the heating process, when the vacuum value is less than a certain value, the vacuum pump can automatically vacuum again to replenish the pressure. When the vacuum value reaches a preset value, the vacuum pump stops vacuuming.

[0037] Optionally, the first control component 40 further includes an alarm, which sounds an alarm when the vacuum value does not reach a preset value within a preset time to alert the staff. For example, after the base 10 is placed at the connection position of the blade, the vacuum pump is ready to start the vacuum pumping action, and stops outputting when the vacuum value inside the adsorption tank 11 reaches -800mbar, and starts the vacuum facility to make up the pressure when the vacuum value is less than -700mbar, and sounds an alarm when the negative pressure value cannot reach -800mbar within 20 seconds.

[0038] In some embodiments, the heating component 30 includes a first shell 31 connected to the connecting component 20 and a heating source 32 connected to the first shell 31. The first shell 31 has a third surface M3 on the side facing away from the connecting component 20. The third surface M3 is recessed inward to form a groove structure 311. The heating source 32 is connected to the bottom wall of the groove structure 311. The side surface of the heating source 32 away from the bottom wall is located on the side of the third surface M3 facing the bottom wall.

[0039] The heating source 32 heats the blades. The heating source 32 may be an infrared heat source that heats the blades by infrared light or an electric heat source that generates heat by supplying electricity to heat the blades.

[0040] The setting of the first shell 31 can facilitate the connection of the heating source 32 on the one hand, and can also protect the heating source 32 to a certain extent on the other hand. Specifically, the first shell 31 is recessed inward at the third surface M3 to form a groove structure 311, and the heating source 32 is connected to the groove bottom wall of the groove structure 311, and the side surface of the heating source 32 away from the groove bottom wall is located on the side of the third surface M3 facing the groove bottom wall. In other words, the heating source 32 is inside the groove structure 311, and the heat flows out from the opening formed by the groove structure 311 on the third surface M3. When the heating source 32 is an infrared heat source, the side wall of the groove structure 311 can reflect the infrared light generated by the infrared heat source to reflect the infrared light to the area that needs to be heated, which can play a certain role in gathering the infrared light and improve the concentration of infrared light irradiation.

[0041] In some embodiments, the heating assembly 30 also includes a second shell 33 connected to the side wall of the first shell 31, the second shell 33 encloses a heating chamber 331, the second shell 33 forms a first opening on the side facing the first shell 31, the third surface M3 closes the first opening, and the second shell 33 forms a second opening on the side away from the first shell 31, and the inner diameter of the second opening is larger than the inner diameter of the first opening.

[0042] Taking the heating source 32 as an infrared heat source as an example, the setting of the heating cavity 331 can gather the infrared light outside the groove structure 311, so that the infrared light is irradiated to the heating area. Specifically, the heating cavity 331 is formed by the second shell 33 connected to the side wall of the first shell 31. When the infrared light is emitted from the groove structure 311, it enters the heating cavity 331, and the second shell 33 gathers the infrared light.

[0043] The heating cavity 331 forms a first opening on the side facing the first shell 31, and forms a second opening on the side away from the first shell 31. The infrared light enters the heating cavity 331 through the first opening, and is emitted through the second opening and reaches the blade. Considering that the heating area of ​​local heating is generally larger than the area of ​​the heating source 32, the inner diameter of the second opening is set to be larger than the inner diameter of the first opening, so that the infrared light is guided to a certain extent through the second shell 33, thereby improving the accuracy of the infrared light when irradiating to the blade.

[0044] In some embodiments, the heating source 32 includes a strip structure, the heating source 32 extends relative to the first shell 31 along the second direction Y, and the heating source 32 is connected to the two side walls of the groove structure 311 along the second direction Y. The heating assembly 30 includes a first sensor 34 and a second sensor 35 connected to the side of the second shell 33 away from the first shell 31, the first sensor 34 and the second sensor 35 are respectively located on both sides of the heating source 32 along the second direction Y, and the first sensor 34 and the second sensor 35 are configured to monitor the temperature of the blade.

[0045] Furthermore, the heating device also includes a second control component 50 for controlling the heating component 30. The first sensor 34 and the second sensor 35 monitor the temperature of the blades in real time and feed back to the second control component 50. The second control component 50 adopts microcomputer integrated control, which can set the temperature, time and other parameters of the heating component 30, and can also monitor and detect the current and voltage of the heating source 32.

[0046] In some embodiments, the connecting component 20 includes a first part 21, a second part 22 and a third part 23 that are rotatably connected to each other around the second direction Y, the end of the first part 21 away from the second part 22 is fixedly connected to the base 10, and the end of the third part 23 away from the second part 22 is fixedly connected to the heating component 30, and the second direction Y intersects with the first direction X.

[0047] The connecting component 20 includes a first part 21, a second part 22 and a third part 23 which are rotatably connected to each other in a second direction Y. The projection size of the connecting component 20 as a whole in the first direction X is adjusted by the rotation and folding angle between the first part 21, the second part 22 and the third part 23.

[0048] Specifically, in order to ensure the connection stability between the connection component 20 and the base 10, the first part 21 connected to the base 10 is fixedly connected to the base 10. Similarly, in order to ensure the connection stability between the connection component 20 and the heating component 30, the third part 23 connected to the heating component 30 is fixedly connected to the heating component 30. In order to take into account the adjustment flexibility of the connection component 20, the first part 21 is rotatably connected to the second part 22, and the second part 22 is rotatably connected to the third part 23, wherein the second part 22 is the main adjustment structural member of the connection component 20, the extension size of the second part 22 is larger than the extension size of the first part 21 and the third part 23, and the extension size of the first part 21 is smaller, so that the second part 22 can be set close to the base 10, which can reduce the probability of the second part 22 shaking relative to the base 10.

[0049] Optionally, in order to simplify the structure of the heating device, the rotational connection between the first part 21 and the second part 22 is configured as follows: a rotation hole is provided in one of the first part 21 and the second part 22, and a rotation shaft is provided in the other, and an interference fit is formed between the rotation shaft and the rotation hole. The rotation between the second part 22 and the third part 23 is also the same, and will not be described in detail here.

[0050] In some embodiments, the first portion 21 includes a first connector 211 and a second connector 212 spaced apart in the second direction Y, and a first fixing member 213 connected between the first connector 211 and the second connector 212 along the second direction Y, the first fixing member 213 is connected to the second surface M2, and a projection area of ​​the first fixing member 213 in the first direction X is greater than a projection area of ​​the first connector 211 and the second connector 212 in the first direction X. The second portion 22 is connected between the first connector 211 and the second connector 212.

[0051] In order to ensure the connection between the second part 22 and the base 10 and improve the stability of the second part 22 relative to the base 10, a specific arrangement is made for the structure of the first part 21. The first part 21 includes a first connector 211 and a second connector 212 spaced apart in the second direction Y and a first fixing member 213 connected between the first connector 211 and the second connector 212 along the second direction Y. The first connector 211, the first fixing member 213 and the second connector 212 form a U-shaped structure. The first fixing member 213 is connected to the second surface M2, and the second part 22 is connected between the first connector 211 and the second connector 212. In the above manner, the second part 22 can be connected to the inside of the first part 21, so that the center of gravity of the second part 22 is relatively located inside the first part 21, and is connected and supported by the first part 21, so as to reduce the probability of the second part 22 rotating and shaking relative to the first part 21.

[0052] In some embodiments, the second part 22 includes a third connecting member 221 and a fourth connecting member 222 spaced apart in the second direction Y, and a second fixing member 223 connected between the third connecting member 221 and the fourth connecting member 222 along the second direction Y. The third connecting member 221, the second fixing member 223 and the fourth connecting member 222 form a U-shaped structure, and the second fixing member 223 is rotatably connected between the first connecting member 211 and the second connecting member 212. The third part 23 is connected between the third connecting member 221 and the fourth connecting member 222. In the above manner, the third part 23 can be connected to the inside of the second part 22, so that the center of gravity of the third part 23 is relatively located inside the second part 22, and is connected and supported by the second part 22, so as to reduce the probability of the third part 23 rotating and shaking relative to the second part 22.

[0053] In some embodiments, the third part 23 includes a third fixing member 231 extending along the second direction Y and a fifth connecting member 232 connected to the third fixing member 231, a T-shaped structure is formed between the third fixing member 231 and the fifth connecting member 232, an end of the fifth connecting member 232 away from the third fixing member 231 is fixedly connected to the heating component 30, and the third fixing member 231 is connected between the third connecting member 221 and the fourth connecting member 222. In the above manner, the heating component 30 can be connected to the inside of the third part 23, so that the center of gravity of the heating component 30 is relatively located inside the third part 23, and is connected and supported by the third part 23, so as to reduce the probability of the heating component 30 rotating and shaking relative to the third part 23.

[0054] In some embodiments, the heating device includes a first control component 40 and a second control component 50, both of which are connected to the second surface M2. The first control component 40 is configured to control the connection strength between the base 10 and the blade, and the second control component 50 is configured to control the heating component 30.

[0055] The first control component 40 and the second control component 50 are integrated on the base 10, so that the heating device forms a single integral device. When the base 10 and the blades are connected by negative pressure adsorption, the first control component 40 is used to control the vacuum value inside the adsorption groove 11. Alternatively, when the base 10 and the blades are connected by magnetic adsorption, the first control component 40 is used to control the degree of magnetism of the base 10. The second control component 50 is used to control the temperature and duration of the heating component 30 and other parameters.

[0056] In some embodiments, the first control component 40 and the second control component 50 are respectively located on both sides of the first fixing member 213, and the extension dimension of the first control component 40 along the first direction X is smaller than the extension dimension of the first connecting member 211 and the second connecting member 212 along the first direction X, and the extension dimension of the second control component 50 along the first direction X is smaller than the extension dimension of the first connecting member 211 and the second connecting member 212 along the first direction X.

[0057] The first control component 40 and the second control component 50 are arranged on both sides of the first fixing member 213, so as to improve the symmetry of the relevant structural components arranged on the second surface M2 and improve the stability of the base 10 itself. At the same time, in order to reduce the influence of the first control component 40 on the rotation of the connecting component 20, the extension dimension of the first control component 40 along the first direction X is set to be smaller than the extension dimension of the first connecting member 211 and the second connecting member 212 along the first direction X, so as to reduce the influence of the first control component 40 on the rotation of the connecting component 20. The second control component 50 is the same, and will not be described in detail here.

[0058] In some embodiments, in order to reduce the overall weight of the heating device, the first part 21 and / or the second part 22 are provided with a through hole structure. Without affecting the connection of the connection component 20 itself, the through hole structure is set to a relatively large form. Further, in order to facilitate the installation and inspection of the first control component 40 and the second control component 50, the first control component 40 is provided with a corresponding through hole on the first part 21, and similarly, the second control component 50 is provided with a corresponding through hole on the first part 21.

[0059] Second, as Figure 4 As shown, the embodiment of the present application provides a heating method, which is based on the heating device provided in the first aspect of the embodiment of the present application. The heating method includes: S1, connecting the base 10 to the blade, wherein the base 10 is connected to the blade by negative pressure adsorption; S2, adjusting the extension size of the connecting component 20; S3, using the heating component 30 to heat the blades.

[0060] In S1, the base 10 is connected to the blade. The base 10 is connected to the blade by negative pressure adsorption. The base 10 and the surface of the blade are wiped clean. The base 10 corresponds to the connection position on the blade. The vacuum switch of the vacuum pump is turned on to adsorb the base 10 on the blade. The first control component 40 can turn on the vacuum device when receiving the start command. When the vacuum value reaches the preset -800mbar, the output is stopped. When the vacuum value is less than -700mbar, the vacuum facility is turned on for pressure replenishment. When the vacuum value cannot reach -800mbar within 20 seconds, an alarm is issued. The first control component 40 will continue to turn on the vacuum pump and cut off the power supply of the heating component 30 to prevent the heating device from tipping over and causing an accident.

[0061] In S3, when the blades are heated by the heating component 30, an infrared heat source is used for heating, and a first sensor 34 and a second sensor 35 are set to monitor the state of the heating component 30 in real time, and the temperature of the blades is monitored, and the surface temperature of the blades is fed back to the second control component 50. The second control component 50 adopts microcomputer integrated control, and parameters such as temperature and time can be set. It also has the function of monitoring and detecting the current and voltage of the heating source 32.

[0062] In some embodiments, in S3, when the blade is heated by the heating component 30, when the negative pressure value of the base 10 on the blade is less than a preset value, the heating component 30 stops heating the blade.

[0063] The first control component 40 and the second control component 50 supervise each other. When the vacuum value between the base 10 and the blade drops and triggers the alarm of the first control component 40, the second control component 50 cuts off the power to the heating component 30, and the heating component 30 stops working. When the second control component 50 fails, the first control component 40 continues to work to ensure safety. The heating device is also designed with a vibration power-off function. When the device falls off due to external dragging or impact, the vibration power-off function is activated, and the second control component 50 cuts off the power supply of the heating component 30 to ensure safety.

[0064] With the combined use of the first control component 40 and the second control component 50, the heating device can be connected to the mobile electronic device by communication and controlled by the mobile electronic device, and the program settings and parameters are all set on the mobile electronic device. The heating curve during operation can also be recorded in real time and retrieved at any time using a mobile device. When the heating device issues an alarm, not only will the alarm sound on the heating device, but the mobile electronic device will also receive an alarm prompt when it is in a connected state, so as to provide comprehensive prompts to the staff.

[0065] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
