Description
Technical Field
[0001] The present application relates to the technical field of wind turbines, and particularly to a blade profile landscape device for a wind turbine. Background Art
[0002] A wind turbine is a pollution-free clean energy device that uses wind energy to generate electricity. It uses the wind to blow the blades of the wind turbine to rotate, driving an electromagnetic induction generator to generate electricity. The wind in nature is constantly changing and is always in an unstable state. The rotational speed of the wind turbine blades generally changes continuously with the magnitude of the wind, which also causes the rotational speed of the generator to change continuously. The voltage it generates fluctuates, the current is extremely unstable, the output power varies greatly, and the average efficiency is relatively low. Therefore, the power provided by traditional small wind turbines cannot be directly used by electrical appliances, let alone directly grid-connected power generation. When using a current small wind turbine, the battery is generally charged first, and then the battery is used to supply power to external loads. For example, for a wind-solar hybrid street lamp, it generally uses a 24V - 48V battery to supply power to the street lamp.
[0003] For existing wind turbines, especially horizontal-axis wind turbines, the axis of their blades is in the horizontal direction, and the normal direction of the tip sweep plane of the wind wheel is horizontal. Especially for large wind turbines with long blades, they are not very friendly to flying birds or aircraft such as drones, and are prone to accidentally injuring birds or colliding with passing drones.

[0044] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments.
[0045] In one embodiment, as Figure 1 and Figure 5 shown, a blade profile landscape device for a wind turbine is provided. The blade profile landscape device includes: a wind turbine main body, an irradiation lamp module 20, a radio transmission module 30, a photosensitive module 40, and a control circuit module 50.
[0046] The main body of the wind turbine includes a hub 112 for rotating with the blade 122, a fairing 114 for covering the hub 112, a nacelle 116 for housing the generator 110, and a rotating shaft disposed between the hub 112 and the generator 110; a gap portion 118 is provided between the hub 112 and the nacelle 116; an illumination lamp module 20 is disposed on the inner wall of the fairing 114, and the illumination lamp module 20 is used to illuminate the blade 122; the radio transmission module 30 includes a wireless transmission module 310 and a wireless reception module 312; the wireless transmission module 310 is located in the gap portion 118 and is disposed close to the nacelle 116; the wireless reception module 312 is located in the gap portion 118 and is disposed close to the hub 112, and the wireless reception module 312 is electrically connected to the illumination lamp module 20; a photosensitive module 40 is disposed on the main body of the wind turbine; the control circuit module 50 is electrically connected to the wireless transmission module 310, the photosensitive module 40, and the generator 110 respectively.
[0047] Among them, the wind turbine is used to utilize the wind to blow the blade 122 to rotate, and then drive the electromagnetic induction generator 110 to generate electricity. The main body of the wind turbine includes the generator 110 and the blade 122; the wind turbine further includes the hub 112, the nacelle 116, the fairing 114 and the rotating shaft. The nacelle 116 is used to store the generator 110, preventing the generator 110 from being exposed to the external environment and playing a protective role for the generator 110. The nacelle 116 is fixedly disposed on the bracket of the wind turbine. The hub 112 is used to rotate with the blade 122. When the blade 122 rotates under the influence of the wind, the blade 122 drives the hub 112 to rotate. The fairing 114 is used to cover the hub 112. It should be noted that the fairing 114 is also called the hub 112 cover, the hub 112 cap, etc., and refers to the outer protective cover of the fan hub 112. Since in the windward state of the fan, the airflow will be evenly divided according to the streamline of the fairing 114. Exemplarily, the fairing 114 is a convex structure, so that the fairing 114 forms a hollow cavity, and then can cover the outer side surface of the hub 112. When the blade 122 rotates under the influence of the wind, it drives the hub 112 to rotate, and then drives the rotating shaft to rotate through the hub 112. Based on the rotating shaft being disposed between the hub 112 and the nacelle 116, the rotating shaft drives the generator to generate electromagnetic induction, so that the generator 110 generates electricity.
[0048] Such as Figure 6As shown, a clearance part 118 is provided between the wheel hub 112 and the generator nacelle 116. The clearance part 118 can be used to accommodate the radio transmission module 30. Exemplarily, in order to ensure that there is no mechanical interference between the rotating blade 122 and the generator nacelle 116, the interval of the clearance part 118 can be set at any distance between 5 and 20 mm. The radio transmission module 30 includes a wireless transmission module 310 and a wireless reception module 312. The wireless transmission module 310 is located in the clearance part 118 and is arranged close to the generator nacelle 116; the wireless reception module 312 is located in the clearance part 118 and is arranged close to the wheel hub 112. For example, the wireless transmission module 310 can include a wireless transmission coil, and the wireless reception module 312 can include a wireless reception coil. The wireless transmission coil and the wireless reception coil are sleeved in the clearance part 118. By simultaneously adjusting the parallelism and distance between the wireless transmission coil and the wireless reception coil, it is ensured that the wireless power transmission and reception functions are normal. Exemplarily, the wireless transmission coil is fixedly arranged on the side of the generator nacelle 116, and the wireless reception coil is fixedly arranged on the side of the wheel hub 112. By adopting the wireless power transmission mode, the radio transmission module 30 is installed in the clearance part 118 between the wheel hub 112 rotating with the blade 122 and the stationary generator nacelle 116. The wireless transmission module 310 is installed on the stationary generator nacelle 116 side, and the wireless reception module 312 is installed on the wheel hub 112 side rotating with the blade 122. There is no need to pass a wire through the center of the rotating shaft of the wind turbine, and there is no need for a rotating slip ring for passing the wire, which simplifies the product structure, improves the product reliability, and reduces the failure rate.
[0049] In order not to damage the surface and mechanical structure of the blade 122 and to achieve the landscape and warning effects, the illumination lamp module 20 can be installed on the inner wall of the fairing 114 facing the corresponding blade 122, so as to realize that the illumination lamp module 20 is arranged on the inner wall of the fairing 114, and further enable the light of the illumination lamp module 20 to irradiate on the blade 122. Exemplarily, by adjusting the lamp body inclination angle of the illumination lamp module 20, the light emitted by the illumination lamp module 20 is irradiated on the entire side surface of the blade 122, so as to realize that the light of the illumination lamp module 20 comprehensively irradiates and covers the entire length of the wind turbine blade 122. By installing the illumination lamp module 20 on the inner wall of the fairing 114 at the front end of the wind turbine. As long as a small hole is opened to expose the lamp head of the illumination lamp module 20, it is easy to seal it back tightly. Adjusting the angle and fixing the entire illumination lamp module 20 can be operated in the space inside the fairing 114. There is no need to drill screw holes on the wind turbine blade 122 to fix the illumination lamp module 20, or use other super sticky substances on the blade 122 to fix the illumination lamp module 20, so the blade 122 will not be damaged and the service life of the blade 122 will not be prematurely reduced.
[0050] By arranging the photosensitive module 40 on the main body of the wind turbine; the wireless receiving module 312 is electrically connected to the illumination lamp module 20; the control circuit module 50 is respectively electrically connected to the wireless transmitting module 310, the photosensitive module 40 and the generator. Then, after the control circuit module 50 receives the signal from the photosensitive module 40 and determines it is the night operation mode, it issues an instruction to control the wireless transmitting module 310 to conduct, delivering electrical energy to the wireless transmitting module 310. The high-frequency oscillating magnetic field of the wireless transmitting module 310 is received by the wireless receiving module 312 and converted into an oscillating current. After the electrical energy is electrically processed by the wireless receiving module 312, it is delivered to the illumination lamp module 20, realizing that when night is detected, the illumination lamp module 20 lights up, making the light of the illumination lamp module 20 shine on the corresponding blade 122, playing a role in landscape decoration and warning. When daybreak is detected, the photosensitive module 40 generates a closing signal, and then the control circuit module 50 controls the illumination lamp module 20 to close, thus realizing that when daybreak is detected, the illumination lamp module 20 goes out. By setting a warning outline device on the wind turbine blade 122, it plays a warning role for flying objects such as birds and drones or large vehicles driving on the road surface, reducing unnecessary accidental collision accidents.
[0051] In the above-mentioned embodiment, by arranging the wireless transmitting module 310 in the gap portion 118 and close to the generator nacelle 116; the wireless receiving module 312 is arranged in the gap portion 118 and close to the hub 112, and the wireless receiving module 312 is electrically connected to the illumination lamp module 20. Then, there is no need to pass a wire through the center of the wind turbine rotating shaft, and there is no need for a rotating slip ring for wire threading. The design is simple and reliable, reducing the failure rate; by arranging the illumination lamp module 20 on the inner wall of the fairing 114, the illumination lamp module 20 is used to illuminate the blade 122; as long as a small hole is opened to expose the lamp head of the illumination lamp module 20, it is easy to seal it tightly back. There is no need to drill screw holes on the wind turbine blade 122 to fix the illumination lamp module 20, or use other super sticky substances on the blade 122 to fix the illumination lamp module 20, which will not damage the blade 122 and avoid premature reduction of the blade 122 life. At the same time, the warning and obstacle avoidance effects are improved; by arranging the photosensitive module 40 on the main body of the wind turbine; the control circuit module 50 is respectively electrically connected to the wireless transmitting module 310, the photosensitive module 40 and the generator. Then, according to the detection signal of the photosensitive module 40, the opening and closing of the illumination lamp module 20 can be automatically controlled, improving the intelligent level of the outline control of the wind turbine blade 122.
[0052] In one embodiment, the illumination lamp module includes illumination lamps connected to the wireless receiving module, the number of illumination lamps is equal to the number of blades, and the illumination range of the illumination lamps covers the side area of the corresponding blade.
[0053] Among them, the number of irradiation lamps is equal to the number of blades, and the number of irradiation lamps can be changed according to the number of blades of the wind turbine. For example, if the wind turbine is a two-blade wind turbine, the number of irradiation lamps is set to 2 (such as the first irradiation lamp and the second irradiation lamp), then the first irradiation lamp is used to irradiate one of the blades of the two-blade wind turbine, and the second irradiation lamp is used to irradiate the other blade of the two-blade wind turbine. If the wind turbine is a three-blade wind turbine, the corresponding number of irradiation lamps is 3; if the wind turbine is a four-blade wind turbine, the corresponding number of irradiation lamps is 4.
[0054] It should be noted that in the traditional method of installing irradiation lamps on the blades of a wind turbine, it is necessary to consider drilling holes on the blades to fix the irradiation lamps, or using materials with strong adhesiveness and not afraid of sun and rain to fix the irradiation lamps on the blades. Although these measures can achieve the purpose, after a long time, it may cause premature damage and corrosion of the blades. In order not to damage the blade surface and mechanical structure, and to achieve the landscape and warning effects, irradiation lamps are vertically installed on the inner wall of the fairing facing the direction of the blades. By adjusting the inclination angle of the lamp body of the irradiation lamp, the irradiation range of the irradiation lamp covers the side area of the corresponding blade.
[0055] When the blades of the wind turbine do not rotate and it is detected as night through the photosensitive module, the internal power storage module of the control circuit module can supply power to the irradiation lamps, so that the blades will present static light. When the blades rotate rapidly and it is detected as night through the photosensitive module, the blades will form a circular ring of light, presenting a landscape effect at night, which can achieve the warning and obstacle avoidance effects, and can also achieve the night urban landscape effect.
[0056] In a specific embodiment, the irradiation lamp includes at least one LED lamp connected to a wireless receiving module, and the irradiation range of the LED lamp covers the side area of the corresponding blade.
[0057] Among them, the irradiation lamp can be composed of at least one LED lamp. For example, when the irradiation lamp is composed of one LED lamp, the irradiation range of the LED lamp covers the entire side area of the corresponding blade. When the irradiation lamp is composed of two LED lamps, the side of the corresponding blade can be divided into 2 areas, and the irradiation range of one LED lamp covers one area, and the irradiation range of the other LED lamp covers the other area, that is, the overall side area of the corresponding blade is covered by the irradiation light of the two LED lamps.
[0058] In one embodiment, as Figure 2 and Figure 8As shown, the illuminating lamp includes a first-color LED lamp 210, a second-color LED lamp 212, and a third-color LED lamp 214; the side surface of the blade 122 is divided into a first illumination area, a second illumination area, and a third illumination area; the illumination range of the first-color LED lamp 210 covers the first illumination area of the corresponding blade 122, the illumination range of the second-color LED lamp covers the second illumination area of the corresponding blade 122, and the illumination range of the third-color LED lamp 214 covers the third illumination area of the corresponding blade 122.
[0059] Among them, the light-emitting color of the first-color LED lamp 210 can be red, the light-emitting color of the second-color LED lamp 212 can be green, and the light-emitting color of the third-color LED lamp 214 can be blue. It should be noted that the light-emitting color combinations of the first-color LED lamp 210, the second-color LED lamp 212, and the third-color LED lamp 214 can also be other color combinations.
[0060] The side surface of the blade 122 is divided into a first illumination area, a second illumination area, and a third illumination area; on the inner wall of the fairing corresponding to the blade 122, there are a first-color LED lamp 210, a second-color LED lamp 212, and a third-color LED lamp 214. By adjusting the lamp body inclination angles of the first-color LED lamp 210, the second-color LED lamp 212, and the third-color LED lamp 214, the first-color LED lamp 210 irradiates the first illumination area (i.e., the area of the blade 122 close to the center), the second-color LED lamp 212 irradiates the second illumination area (i.e., the middle area of the blade 122), and the third-color LED lamp 214 irradiates the third illumination area (i.e., the outer edge area of the blade 122). Based on the different light-emitting colors of the first-color LED lamp 210, the second-color LED lamp 212, and the third-color LED lamp 214, the combined illumination effect of the three-color LED lamps covers the entire length of the corresponding blade 122 of the wind turbine. Thus, when the blade 122 of the wind turbine does not rotate, the blade 122 will present three static colors, distributed from the center to the tip of the blade 122. As Figure 9 shown, when the blade 122 of the wind turbine rotates rapidly, three concentric rings of different colors will be formed from the inside to the outside, presenting a magnificent landscape effect at night, which can achieve the warning and obstacle avoidance effects, and can also achieve the night urban landscape effect.
[0061] It should be noted that the illuminating lamp can also be composed of multiple different-color LED lamps including four different-color LED lamps or five different-color LED lamps, etc. For the setting methods of multiple different-color LED lamps, reference can be made to the above embodiments, and details will not be elaborated here.
[0062] In one embodiment, as Figure 7As shown, the shape of the wireless transmission module 310 is a flat circular ring; the shape of the wireless reception module 312 is a flat circular ring.
[0063] Exemplarily, the wireless transmission module 310 includes a wireless transmission coil, and the wireless reception module 312 includes a wireless reception coil. Both the wireless transmission coil and the wireless reception coil are in the shape of a flat circular ring and have a relatively large hollow part in the middle. The diameter of the hollow part in the middle of the wireless transmission coil and the wireless reception coil is larger than the diameter of the rotating shaft of the wind turbine, which facilitates embedding the wireless transmission coil and the wireless reception coil into the gap for installation. By installing the wireless transmission coil of the wireless transmission module 310 and the wireless reception coil of the wireless reception module 312 on both sides of the gap portion 118, and at the same time adjusting the parallelism and distance between the wireless transmission coil and the wireless reception coil, the normal functions of wireless power transmission and reception are ensured.
[0064] Furthermore, the wireless transmission coil and the wireless reception coil can be respectively concentric with the hub of the wind turbine, fixed tightly to the plane, avoiding the screw hole positions, and at the same time ensuring that when the blade 122 rotates, they do not interfere with each other. It should be noted that if the selected wireless transmission coil and wireless reception coil do not cover the entire circumference but only a part of the circular ring, when the blade 122 rotates, causing the wireless transmission coil and the wireless reception coil to be not directly opposite or too far apart, the illumination lamp module 20 will be powered off briefly, and a flickering phenomenon will be seen at low speeds, affecting the visual experience.
[0065] Furthermore, the wireless transmission module 310 further includes a circuit board connected to the wireless transmission coil, and the circuit board of the wireless transmission module 310 can be installed inside the chassis of the control circuit module. The wireless reception module 312 further includes a circuit board connected to the wireless transmission coil, and the circuit board of the wireless transmission module 310 is installed inside the rotating blade 122 structure. For example, the circuit board of the wireless transmission module 310 can be installed on the inner wall of the fairing.
[0066] In one embodiment, as Figure 3 shown, the control circuit module includes a power conditioning circuit 510, a power storage module 520, and a control main board 530 connected between the power conditioning circuit 510 and the power storage module 520; the power conditioning circuit 510 is connected to the generator; the control main board 530 is respectively connected to the wireless transmission module 310 and the photosensitive module 40.
[0067] Among them, the power conditioning circuit 510 can be used to rectify, filter, etc. the three-phase electricity output by the generator and output the conditioned electrical signal. The power storage module 520 can be used to store the electrical signal conditioned by the power conditioning circuit 510. For example, the power storage module 520 can be a lithium storage battery.
[0068] Based on the control main board 530 being connected between the power conditioning circuit 510 and the energy storage module 520, and the power conditioning circuit 510 being connected to the generator; the control main board 530 is respectively connected to the wireless transmission module 310 and the photosensitive module 40. Furthermore, when the blade 122 rotates under the action of wind force, it drives the generator to work, so that the generator outputs a three-phase electrical signal. After the three-phase electrical signal is conditioned by the power conditioning circuit 510, the conditioned electrical signal is stored in the energy storage module 520 through the control main board 530. The photosensitive module 40 monitors the optical signal of the current environment in real time. After the control main board 530 receives the optical signal from the photosensitive module 40, if it is judged to be the night operation mode, it controls the channel between the wireless transmission module 310 and the energy storage module 520 to conduct, and transmits electrical energy to the wireless transmission module 310 through the energy storage module 520. The wireless transmission module 310 generates a high-frequency oscillating magnetic field, and the oscillating magnetic field is received by the wireless receiving module 312 and converted into an oscillating current. After the electrical energy is electrically processed by the wireless receiving module 312, it is transmitted to the illumination lamp module 20, so that when it is detected that it is night, the illumination lamp module 20 is lit, and the light of the illumination lamp module 20 irradiates on the corresponding blade 122, playing a role in landscape decoration and warning. After the control main board 530 receives the optical signal from the photosensitive module 40, if it is judged to be the dawn mode, the control main board 530 controls the channel between the wireless transmission module 310 and the energy storage module 520 to be disconnected, and then turns off the illumination lamp module 20, so that when it is detected that it is dawn, the illumination lamp module 20 is turned off, and then it plays a warning role for flying objects such as birds and drones or large vehicles driving on the road surface, reducing unnecessary accidental collision accidents.
[0069] In one embodiment, as Figure 3 shown, the power conditioning circuit 510 includes a rectifying circuit 512 and a filtering circuit 514; the input end of the rectifying circuit 512 is connected to the generator, the output end of the rectifying circuit 512 is connected to the input end of the filtering circuit 514, and the output end of the filtering circuit 514 is connected to the control main board 530.
[0070] Among them, the rectifying circuit 512 can be used to rectify the three-phase electrical signal output by the generator, and then output a direct current electrical signal. The filtering circuit 514 can be used to filter the rectified direct current electrical signal, and then filter out the noise signal, and transmit the filtered signal to the energy storage module 520 through the control main board 530.
[0071] In one embodiment, as Figure 3 shown, the blade profile landscape device for a wind turbine further includes an LED street lamp 60 connected to the control main board 530.
[0072] Among them, based on the connection between the LED street lamp 60 and the control main board 530, after the control main board 530 receives the optical signal from the photosensitive module 40, if it is judged to be in the night operation mode, it controls the channel between the energy storage module 520 and the LED street lamp 60 to conduct, and supplies power to the LED street lamp 60 through the energy storage module 520 to realize the lighting operation of the LED street lamp 60. At the same time, it controls the channel between the wireless transmission module 310 and the energy storage module 520 to conduct, and transmits electrical energy to the wireless transmission module 310 through the energy storage module 520. The wireless transmission module 310 generates a high-frequency oscillating magnetic field, and the oscillating magnetic field is received by the wireless receiving module 312 and converted into an oscillating current. After the electrical energy is electrically processed by the wireless receiving module 312, it is transmitted to the illumination lamp module 20. When it is detected that it is night, the illumination lamp module 20 is lit, so that the light of the illumination lamp module 20 irradiates on the corresponding blades 122, playing a role in landscape decoration and warning. If it is judged to be the dawn mode, it controls the channel between the energy storage module 520 and the LED street lamp 60 to disconnect, so that the LED street lamp 60 goes out. At the same time, the control main board 530 controls the channel between the wireless transmission module 310 and the energy storage module 520 to disconnect, and then turns off the illumination lamp module 20.

[0074] Among them, after the control main board 530 receives the optical signal from the photosensitive module 40, if it is judged to be in the night operation mode, it controls the first switch to conduct, so that the channel between the energy storage module 520 and the LED street lamp 60 conducts, and supplies power to the LED street lamp 60 through the energy storage module 520 to realize the lighting operation of the LED street lamp 60. At the same time, it controls the second switch to conduct, so that the channel between the wireless transmission module 310 and the energy storage module 520 conducts, and transmits electrical energy to the wireless transmission module 310 through the energy storage module 520. The wireless transmission module 310 generates a high-frequency oscillating magnetic field, and the oscillating magnetic field is received by the wireless receiving module 312 and converted into an oscillating current. After the electrical energy is electrically processed by the wireless receiving module 312, it is transmitted to the illumination lamp module 20. When it is detected that it is night, the illumination lamp module 20 is lit, so that the light of the illumination lamp module 20 irradiates on the corresponding blades 122, playing a role in landscape decoration and warning. If it is judged to be the dawn mode, it controls the first switch to disconnect, so that the channel between the energy storage module 520 and the LED street lamp 60 disconnects, so that the LED street lamp 60 goes out. At the same time, the main board controls the second switch to disconnect, so that the channel between the wireless transmission module 310 and the energy storage module 520 disconnects, and then turns off the illumination lamp module 20.
