Description

Technical Field

[0001] The present invention relates to the technical field of wind turbines, and specifically to wind turbines.

Background Art

[0002] Wind power generation is a renewable energy technology that converts the kinetic energy of wind into electrical energy. Modern wind power generation originated from the energy crisis at the end of the 20th century and the increasing awareness of environmental protection. Due to concerns about dependence on traditional fossil fuels and global greenhouse gas emissions, wind power generation has gradually attracted attention as a clean and renewable energy option. The development of wind turbines has advanced rapidly. In recent years, with the continuous progress of technology and the reduction of costs, wind power generation has already become one of the most important renewable energies in the world. Many countries are vigorously developing wind power generation, which not only provides a reliable alternative for energy supply but also has a positive significance in reducing carbon emissions and addressing climate change.

[0003] However, there are the following problems in the existing blades of wind turbines (for example, the "blades of wind turbines" described in CN102086845B). 1. The heating device is insufficient. When the temperature drops in winter, icing or snow accumulation occurs on the blades of the wind turbine, which not only affects the power generation efficiency but may even cause the operation of the wind power generation unit to stop. 2. The night alarm device is insufficient. At night, it is difficult for pilots of aircraft, drivers of ground vehicles, and birds, etc. to identify the exact position of the blades of the wind turbine, which is likely to cause safety risks.

They are used solely to distinguish components or operations described in the same technical terminology and should not be interpreted as indicating relative importance or the number of technical features. Accordingly, features limited by "first," "second," etc., shall explicitly or implicitly include at least one such feature. Also, while the technical proposals and technical features between each embodiment can be combined with each other, this is on the basis that they are feasible to those skilled in the art. If a combination of technical proposals results in a contradiction or impracticality, such a combination of technical proposals shall not exist and shall not be included in the scope of protection required by this invention. The technical proposals of this invention will be described in more detail below through the drawings and embodiments. [Examples]

[0017] Embodiments of the present invention provide wind turbine blades and a wind turbine equipped with said blades, as shown in Figures 1 to 3. The wind turbine blades include a blade body 7, and a plurality of blade bodies 7 are mounted on a hub 6 at the same angle, and a night alarm device 5 is mounted on the blade body 7. The use of a three-blade design for the multiple blade bodies 7 is recommended.

[0018] Two reinforcing support plates 12 are provided inside the blade body 7, spaced apart on the left and right sides. The reinforcing support plates 12 are fixedly connected to the front and rear inner walls of the blade body 7 along the direction of extension of the blade body 7, and a heating device is fixedly installed on the reinforcing support plates 12 inside the blade body 7.

[0019] The nighttime warning device (5) includes a storage battery 1 (8), and the storage battery 1 (8) is fixedly installed on the front and rear outer walls at a position close to the hub (6) of the blade body (7). The storage battery 1 (8) is electrically connected to the spotlight 1 (10), and the spotlight 1 (10) irradiates from the hub (6) side towards the end of the blade body (7). A plurality of sets of spotlights 2 (11) are attached at the same intervals from the end close to the hub (6) of the blade body (7) to the end. The spotlight 2 (11) is electrically connected to the storage battery 1 (8), and the spotlight 2 (11) irradiates symmetrically towards both side edges of the blade body (7). The storage battery 1 (8) is electrically connected to the solar panel group 9, and the solar panel group 9 is fixedly connected to the front and rear surfaces of the blade body (7).

[0020] The working principle and beneficial effects of the above technical solution are as follows. As the principle when the nighttime warning device 5 operates, during the day, the solar panel group 9 uses solar energy to generate electricity and stores the electric power in the storage battery 1 (8). At night, the storage battery 1 (8) supplies electric power to the spotlight 1 (10) and a plurality of sets of spotlights 2 (11), and the spotlight 1 (10) irradiates from the hub 6 side of the blade body 7 towards the end side. When the nighttime haze is thick or the visibility of the atmosphere is low, mainly the spotlight 2 (11) is lit to illuminate the blade body 7.

[0021] The wind turbine blade of the present invention and the wind turbine equipped with the blade illuminate the wind turbine blade by the nighttime warning device 5 installed on the blade body 7, and quickly issue warnings to the pilots of aircraft and birds, thereby avoiding the situation that the aircraft at night collides with the wind turbine blade and causes damage or hinders the normal operation of the wind turbine blade. The heating system and the temperature measurement system cooperate to operate, and when the temperature in winter is low, the internal temperature of the wind turbine blade is heated, so as to heat the outer wall of the wind turbine blade and achieve the effect of melting the ice and snow on the surface of the wind turbine in winter. Thereby, it avoids the wind turbine blade from being damaged by ice and snow and extends the service life of the wind turbine blade.

Embodiment

[0023] A controller 20 is fixedly connected to the end of the inner wall of the blade body 7 closest to the hub 6, and the controller 20 is electrically connected to the circulation pump 17. Multiple temperature sensors 21 are provided on the inner wall surfaces of the front and rear of the blade body 7, and the temperature sensors 21 are connected to the controller (20). The heating pipe network uses lightweight pipes, such as plastic pipes, which reduces the load on the blade body 7.

[0024] The operating principle of the above proposed technology is as follows: When the wind turbine is operating in winter or when the temperature is low, if multiple temperature sensors 21 in the temperature measurement system detect that the temperature inside the blade body 7 has fallen below a set value, the heating system is activated. At this time, the electrically heated water tank 14 heats the water, and each circulation pump 17 operates to send the heated hot water to the inlet of the heating pipe network 13 via the outlet pipe 15 and hose 1 (18). After the hot water has circulated once, it returns from the outlet of the heating pipe network 13 to the electrically heated water tank 14 via hose 2 (19) and inlet pipe 16. If the temperature sensor 21 detects that the temperature is too high, heating of the electrically heated water tank 14 stops, and the circulation pump continues to operate, heating and melting the ice layer and snow outside the blade body 7.

[0025] The beneficial effects of the above proposed technology are as follows: The heating system heats water using an electrically heated water tank 14, and a heating pipe network 13 is installed inside the blades, utilizing the heat generated by the water flow passing through the pipes for heating. The advantages of this heating method are that it allows for more uniform heating by forming a circulating water channel inside the blades, and at the same time does not increase the weight of the blades. As a result, the ice layer and snow accumulation on the surface of the wind turbine blades melt rapidly, effectively protecting the normal operation of the wind turbine blades. [Examples]

[0031] The lifting and lowering component 37 includes a ball screw mounting seat 38, the ball screw mounting seat 38 being fixedly connected to the bottom of the internal screw slider 36 in the front-rear direction, a ball screw motor 2(39) being mounted on the top of the ball screw mounting seat 38, a ball screw 2(40) being fixedly connected to the output shaft of the ball screw motor 2(39), the ball screw 2(40) being rotatably connected to the ball screw mounting seat 38, the ball screw 2(40) being screw-connected to the slider 3(41), a slide rod 42 being fixedly connected to the rear end of the slider 3(41) in the front-rear direction, and the slide rod 42 being slidably connected to the rear end of the ball screw mounting seat 38.

[0032] The operating principle of the above proposed technology is as follows: After long-term operation, a large amount of dust accumulates on the top of the housing of the power generation unit 4 (for example, dust enters through heat dissipation holes installed in the cabin where the power generation unit is installed). This affects the heat dissipation efficiency and service life of the power generation unit 4. Therefore, it is necessary to periodically operate the heat dissipation auxiliary dust removal device 22 to remove dust adhering to the uneven surface of the casing of the power generation unit 4. When performing cleaning and dust removal work, The position adjustment device operates first, and within it, the slide drive mechanism moves back and forth. The battery 2 (26) supplies power to the drive motors 27 on both the front and rear sides, causing them to operate synchronously. The drive motors 27 move the spur gear 1 (28) to move along the rack 1 (24), and the displacement sensor 29 records the displacement of the slide base 25, thereby advancing the slide base 25 along the direction of the guide rail 1 (23) to the target position. Simultaneously, the bonding mechanism operates synchronously, and the electric telescopic rods 30 on both the left and right sides adjust the distance between the cleaning and dust removal mechanism and the power generation unit 4 according to the undulations of the casing surface of the power generation unit 4. The right-side slide groove 1 (32) and slider 1 (33) slide, thereby adapting to slight changes in the left-right direction during adjustment. After the slide drive mechanism has moved to a certain distance, the ball screw motor 1 (34) rotates the bidirectional screw ball screw 35, thereby synchronously sliding the left and right internal screw sliders 36 toward the inward center. The lifting and lowering component 37 operates simultaneously, and the rotation of the ball screw motor 2(39) along with the slider of the internal screw slider 36 drives the rotation of the ball screw 2(40), moving the slider 3(41) downward and closer to the surface housing of the power generation unit 4. The distance sensor detects this in real time and provides real-time feedback adjustments to the ball screw motor 2(39) to prevent excessive proximity to the surface housing of the power generation unit 4. Subsequently, the cleaning and dust removal mechanism is activated, and the storage battery 3(47) supplies power to the cleaning motor 45. When the cleaning motor 45 rotates, it rotates the pulley 1(46), which in turn rotates the pulley 2(50) and the cleaning roller 49 synchronously via the belt 1(51). At the same time, the rotation of the pulley 1(46) causes the pulley 3(54) and the cam 1(55) to rotate synchronously within the L-shaped frame 52 via the belt 2(56). The cam 1(55) presses the vertical rod 58 and spring 59 back and forth, causing the vertical rod 58 and spring 59 to move the dust scraper 57 up and down, thereby scraping out clumps of dust from the recesses in the surface housing of the power generation unit 4 and facilitating further cleaning of the cleaning roller 49. Simultaneously, pulley 1 (46) rotates synchronously with pulley 4 (65) and the blades in dust collection fan 64 via belt 3 (66), generating a negative pressure airflow. The dust swept out by cleaning roller 49 is then sucked into dust collection box 63 via dust collection hood 61, dust collection pipe 53, and dust collection fan 64, completing the collection operation. Wireless camera 60 provides ground personnel with image data of the dust accumulation in the dust collection box throughout the entire process, enabling more efficient cleaning and dust removal.

[0033] The beneficial effects of the above-mentioned technical proposal are as follows: The heat dissipation assist dust removal device 22, through the combination of a slide drive mechanism and a bonding mechanism, skillfully adapts its operation to the surface irregularities and unevenness of the housing of the power generation unit 4, enabling effective cleaning and dust removal of the housing of the wind turbine power generation unit 4. This facilitates the cleaning and dust removal process, is environmentally friendly and highly efficient, and effectively avoids the occurrence of poor heat dissipation and reduced power generation efficiency due to dust accumulation on the outer surface of the power generation unit 4, thereby improving the service life and working environment of the power generation unit 4.
