[0027] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but this must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments.

[0029] The present invention provides the following embodiments

[0030] Example 1

[0031] An embodiment of the present invention provides a wind turbine blade and a wind turbine having the blade, as shown in Figures 1-3, including: a blade body 7, a plurality of blade bodies 7 are installed on a hub 6 at equal angles, and a night warning device 5 is installed on the blade body 7.

[0032] It is recommended that the blade bodies 7 adopt a three-blade mode.

[0033] Two reinforcing support plates 12 are spaced apart on the left and right sides inside the blade body 7 . The reinforcing support plates 12 are fixedly connected to the front and rear inner walls of the blade body 7 along the extension direction of the blade body 7 . A heating device is fixedly installed on the reinforcing support plates 12 inside the blade body 7 .

[0034] The night warning device 5 includes: a storage power supply 8, a storage power supply 8 is fixedly installed on the front and rear outer walls of the blade body 7 near the hub 6, the storage power supply 8 is electrically connected to a spotlight 10, the spotlight 10 shines from the hub 6 end to the end of the blade body 7, and a plurality of groups of spotlights 2 11 are installed at equal intervals from the end near the hub 6 to the end of the blade body 7, the spotlights 2 11 are electrically connected to the storage power supply 8, and the spotlights 2 11 shine symmetrically on both side edges of the blade body 7, the storage power supply 8 is electrically connected to the photovoltaic panel group 9, and the photovoltaic panel group 9 is fixedly connected to the front and rear surfaces of the blade body 7.

[0035] The working principle and beneficial effects of the above technical solution are as follows: when the night warning device 5 is working, the photovoltaic panel group 9 can use solar energy to generate electricity during the day and store the electrical energy in the storage power supply 8. At night, the storage power supply 8 supplies power to the spotlight 10 and several groups of spotlights 2 11. The spotlight 10 shines from the hub 6 end of the blade body 7 to the end. When the fog is thick or the air visibility is low at night, the blade body 7 is mainly illuminated by turning on the spotlight 2 11.

[0036] The present invention provides a wind turbine blade and a wind turbine having the blade. The night warning device 5 installed on the blade body 7 illuminates the wind turbine blade, timely alerting the flying object driver and the flying bird, thereby preventing the flying objects from colliding with the wind turbine blade at night and damaging and polluting the normal operation of the wind turbine blade. Through the cooperation of the heating system and the temperature measurement system, the internal temperature of the wind turbine blade is heated when the temperature is low in winter, thereby heating the outer wall of the wind turbine blade, so that the ice and snow on the surface of the wind turbine are melted in winter, avoiding the wind turbine from being broken by ice and snow, and extending the service life of the wind turbine blade.

[0037] Example 2

[0038] On the basis of Example 1, as shown in FIG3-FIG4, the heating device includes:

[0039] A heating pipe network 13 is provided, and the heating pipe network 13 is fixedly installed on the reinforcing support plate 12 inside the blade body 7. An electric heating water tank 14 is fixedly installed in the center of the hub 6. The electric heating water tank 14 is provided with several groups of water outlet pipes 15 and water inlet pipes 16 corresponding to the direction of the wind turbine blades. The water outlet pipes 15 and the water inlet pipes 16 are fixedly connected to the electric heating water tank 14. A circulating pump 17 is fixedly installed on each group of water outlet pipes 15. The water outlet pipe 15 is connected to hose 18, and hose 18 is connected to the water inlet of the heating pipe network 13. The water inlet pipe 16 is connected to hose 2 19, and hose 2 19 is connected to the water outlet of the heating pipe network 13.

[0040] The inner wall of the blade body 7 near the hub 6 is fixedly connected to the controller 20, which is electrically connected to the circulation pump 17. A plurality of temperature sensors 21 are provided on the front and rear inner wall surfaces of the blade body 7, which are connected to the controller 20. The heating pipe is preferably lightweight, for example, plastic pipe, to reduce the weight of the blade body 7.

[0041] The working principle of the above technical solution is as follows: When the wind turbine is operating in winter or at low temperatures, the temperature sensors 21 in the temperature measurement system detect that the temperature inside the blade body 7 is lower than a preset value, and the heating system is activated. At this time, the electric heating water tank 14 starts heating, and the various circulation pumps 17 work, inputting the heated hot water through the outlet pipe 15 and hose 18 to the water inlet of the heating pipe network 13. After a circle, the hot water flows through the outlet of the heating pipe network 13, hose 2 19, and water inlet pipe 16 and returns to the electric heating water tank 14. If the temperature sensor 21 detects that the temperature is too high, the electric heating water tank 14 stops heating, and the circulation water pump continues to operate, heating and melting the ice and snow outside the blade body 7.

[0042] The beneficial effects of the above technical solution are as follows: the heating system heats water through the electric heating water tank 14, and by installing a heating pipe network 13 inside the blade, the heat generated when the water flows through the pipe network is used for heating. The advantage of this heating method is that a circulating water path can be formed inside the blade, making the heating more uniform, and at the same time will not increase the weight of the blade, so that the ice and snow on the surface of the wind turbine blade melt quickly, effectively protecting the normal use of the wind turbine blade.

A guide rail 23 is fixedly installed on the guide rail frame 62 along the front-to-back direction, and the guide rail 23 is symmetrically fixedly connected to the rack 24 up and down. A sliding seat 25 is slidably connected to the guide rail 23 along the front-to-back direction, and the end of the sliding seat 25 away from the generator set 4 is fixedly connected to the storage power supply 2 26.

[0049] The fitting mechanism includes: an electric telescopic rod 30, the top ends of the sliding seats 25 on the left and right sides are fixedly connected to the electric telescopic rod 30, the electric telescopic rod 30 is electrically connected to the storage power supply 26, the front end of the electric telescopic rod 30 on the left is hinged to the cross frame 31, and the bottom end of the right side of the cross frame 31 is provided with a slide groove 32 along the left and right directions, and the slide groove 32 is connected to a slider 33 for sliding left and right. The bottom end of the slider 33 is hinged to the electric telescopic rod 30 on the left, and a screw motor 34 is fixedly installed on the left end of the cross frame 31. The output shaft of the screw motor 34 is fixedly connected to a bidirectional threaded screw 35, and the bidirectional threaded screw 35 is rotatably connected to the cross frame 31. The left and right opposite thread sections of the bidirectional threaded screw 35 are respectively threadedly connected to an internal threaded slider 36, and the front end of the internal threaded slider 36 is fixedly installed with a lifting and moving component 37. The lifting and moving component 37 is used to push the cleaning and dust removal mechanism slightly closer to fit the outer shell surface of the generator set 4.

[0050] The lifting and moving assembly 37 includes: a screw mounting seat 38, the bottom end of the internal threaded slider 36 is fixedly connected to the screw mounting seat 38 along the front-to-back direction, a screw motor 2 39 is installed at the front end of the screw mounting seat 38, the output shaft of the screw motor 2 39 is fixedly connected to the screw 2 40, the screw 2 40 is rotatably connected to the screw mounting seat 38, the screw 2 40 is threadedly connected to the slider 3 41, the rear end of the slider 31 is fixedly connected to the sliding rod 42 along the front-to-back direction, and the sliding rod 42 is slidably connected to the rear end of the screw mounting seat 38 back and forth.

[0051] The working principle of the above technical solution is: when the generator set 4 has been working for a long time, a lot of dust will accumulate on the top of the outer shell of the generator set 4 (for example, dust enters through the heat dissipation holes set in the engine room where the generator set is located), which affects the heat dissipation efficiency and service life of the generator set 4. Therefore, the heat dissipation auxiliary dust removal device 22 needs to be operated regularly to remove the dust on the uneven outer shell of the generator set 4. When cleaning and dust removal:

[0052] The position adjustment device operates first, with the sliding drive mechanism performing a back-and-forth reciprocating motion. Power supply 26 supplies power to the front and rear drive motors 27, which operate synchronously. Drive motors 27 drive spur gear 1 28 to move on rack 1 24 . Displacement sensor 29 records the displacement of slide 25 , causing slide 25 to advance along guide rail 1 23 to the target position.

[0053] At the same time, the fitting mechanism operates synchronously. The electric telescopic rods 30 on the left and right sides adjust the distance between the cleaning and dust removal mechanism and the generator set 4 according to the undulations of the outer shell surface of the generator set 4. The right chute 32 and slider 33 slide to adapt to the slight changes in the left and right directions during adjustment. When the sliding drive mechanism runs to a certain point, the screw motor 34 is turned on to drive the bidirectional threaded screw 35 to rotate, so that the internal threaded sliders 36 on the left and right sides slide synchronously toward the inner center.

[0054] At the same time, the lifting and moving assembly 37 works: the internal thread slider 36 slides, and the screw motor 2 39 runs to drive the screw 2 40 to rotate, so that the slider 3 41 moves downward close to the surface shell of the generator set 4. At the same time, the distance sensor detects in real time and provides real-time feedback adjustment to the screw motor 2 39 to avoid being too close to the surface shell of the generator set 4.

[0055] Then the cleaning and dust removal mechanism works, the storage power supply 3 47 supplies power to the cleaning motor 45, the cleaning motor 45 drives the pulley 1 46 to rotate, the pulley 1 46 drives the pulley 2 50 and the cleaning roller 49 to rotate synchronously through the belt 1 51, and at the same time, the rotation of the pulley 1 46 drives the pulley 3 54 and the cam 1 55 to rotate synchronously in the L-shaped frame 52 through the belt 2 56, and the cam 1 55 reciprocates back and forth to press the vertical rod 58 and the spring 59, and the vertical rod 58 and the spring 59 drive the scraper 57 to move back and forth, scraping the generator The dust in the depression of the outer shell of the unit 4 is agglomerated, which facilitates further cleaning by the cleaning roller 49. At the same time, the pulley 1 46 drives the pulley 4 65 and the blades in the dust suction fan 64 to rotate synchronously through the belt 3 66, generating a negative pressure airflow, and the dust swept out by the cleaning roller 49 is finally sucked into the dust collection box 63 through the dust collection hood 61, the dust collection pipe 53, and the dust suction fan 64 to complete the collection work. The wireless camera 60 provides the ground personnel with the dust accumulation image data of the dust collection box throughout the process, so as to better carry out the cleaning and dust removal work.

[0056] The beneficial effects of the above technical solution are: the heat dissipation auxiliary dust removal device 22 cooperates with the sliding drive mechanism and the fitting mechanism to cleverly adapt to the surface undulations and concave and convex parts of the generator set 4 shell, and can effectively clean and remove dust from the shell of the wind turbine generator set 4, facilitating the cleaning and dust removal work, being environmentally friendly and efficient, and effectively avoiding the poor heat dissipation caused by dust accumulation on the surface of the generator set 4, thereby reducing the power generation efficiency, and improving the service life and working environment of the generator set 4.

[0057] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
