DETAILED DESCRIPTION

[0052] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0053] Wind turbines are electrical equipment that converts wind energy into mechanical energy and ultimately outputs alternating current. Since wind turbines do not pollute the environment when they are working and have high power generation efficiency, they are widely used in areas with abundant wind resources.

[0054] Wind turbines are mainly composed of impellers, shafts, controllers, gearboxes, brakes, generators, cooling systems, anemometers, wind vanes, yaw systems, etc. The impellers include blades, which rotate through the shaft when there is wind, thereby converting wind power into

[0055] After a long period of use, the anti-corrosion paint on the surface of the blades of the wind turbine rotor will fall off, which can easily cause the blades on the wind turbine rotor to corrode. In order to solve the corrosion problem of the wind turbine rotor blades, the prior art provides a protective cover on the blades and sprays anti-corrosion paint on the outer surface of the protective cover, thereby preventing the blades from being corroded by acid rain and the like, and extending the service life.

[0056] However, the existing wind turbine blade anti-corrosion device solves the problem of blade anti-corrosion by setting a blade protection cover, but since the blade protection cover needs to be connected to the blade by bolts, there is a technical problem that the anti-corrosion device is difficult to install and disassemble. In order to solve this technical problem, the present application proposes a wind turbine blade anti-corrosion device, and its technical concept is:

[0057] The side wall of the locking sleeve is provided with a plurality of locking rods, and the surface of the locking rod and the opening of the locking sleeve cavity facing the same direction is provided with an anti-corrosion component. The anti-corrosion component includes a storage table, a storage slot is provided in the storage table, a rotatable rolling drum is provided in the storage slot, an anti-corrosion curtain is rolled on the rolling drum, and the free end of the anti-corrosion curtain is connected to the push plate outside the storage table, and a locking slot is provided on one side of the locking rod, and the size of the locking slot matches the size of the push plate, so that the push plate can be stuck in the locking slot.

[0058] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0059] In a possible embodiment of the present application, a wind turbine blade anti-corrosion device is provided. Figure 1 Schematic diagram of a wind turbine blade anti-corrosion device provided in an embodiment of the present application. Figure 1 As shown, the device comprises a locking sleeve 1, the size of the inner cavity of the locking sleeve 1 is adapted to the impeller shaft of the wind turbine generator, so that the locking sleeve 1 can be sleeved on the impeller shaft. The inner cavity of the locking sleeve 1 can be a through cavity or a cavity with one end closed.

[0060] A plurality of locking rods 2 are provided on the outer wall of the locking sleeve 1, and the positions of the locking rods 2 correspond to the blade positions of the wind turbine impeller. Since the wind turbine impeller generally has three blades, and the angles between the blades are all 120°, it is preferred that in this embodiment, the number of the locking rods 2 is three, and the angles between the locking rods 2 are 120°, so that after the locking sleeve 1 is sleeved on the impeller shaft, the positions of the locking rods 2 correspond to the blade positions of the wind turbine impeller.

[0061] An anti-corrosion component 7 is fixed on the surface of each locking rod 2. Figure 2 is a schematic diagram of an anti-corrosion component provided in an embodiment of the present application, such as Figure 2 As shown, the anti-corrosion assembly 7 includes a storage table 701, a storage slot 702, a rolling drum 705, an anti-corrosion curtain 706, a push plate 707, and a locking slot 708; wherein,

[0062] A storage slot 702 is provided inside the storage platform 701, a rotatable rolling drum 705 is provided inside the storage slot 702, an anti-corrosion curtain 706 is rolled up on the rolling drum 705, a free end of the anti-corrosion curtain 706 is connected to a push plate 707 outside the storage platform 701, and a fixed end of the anti-corrosion curtain 706 is connected to the rolling drum 705. A locking slot 708 is provided on one side of the locking rod 2, and the size of the locking slot 708 matches the size of the push plate 707, so that the push plate 707 can be inserted into the locking slot 708.

[0063] It should be noted that the push plate 707 is not limited to a plate-like structure, and may also be in other shapes, such as a block shape. Optionally, the groove body of the locking groove 708 may be provided with a locking assembly, and after the push plate 707 is placed in the locking groove 708, the locking assembly locks the push plate 707 to prevent the push plate 707 from falling off.

[0064] The free end of the anti-corrosion curtain 706 can be directly connected to the push plate 707 outside the storage platform 701. Considering that the blades of the wind turbine are placed at high altitude and the wind is strong, a through slot connected to the storage slot 702 can also be provided on the side of the storage platform 701. The size of the through slot matches the size of the anti-corrosion curtain 706, so that after the anti-corrosion curtain 706 passes through the through slot, the free end of the anti-corrosion curtain 706 is connected to the push plate 707 outside the storage platform 701. By providing the through slot on the side of the storage platform 701, the anti-corrosion curtain 706 can be fixed to a certain extent through the through slot to prevent the wind from blowing the anti-corrosion curtain 706 and affecting the installation.

[0065] Specifically, after the locking sleeve 1 is sleeved on the impeller shaft, each locking rod 2 is placed at the position corresponding to the blade, and the push plate 707 is pushed, and the push plate 707 pulls the anti-corrosion curtain 706. Since the anti-corrosion curtain 706 is rolled on the rolling drum 705, when the anti-corrosion curtain 706 is pulled, the anti-corrosion curtain 706 will drive the rolling drum 705 to rotate, thereby releasing the anti-corrosion curtain 706 rolled on the rolling drum 705. Therefore, the push plate 707 is subsequently pulled to bypass the pulled anti-corrosion curtain 706 around the blade, and then the push plate 707 is stuck in the locking groove 708, so that the anti-corrosion treatment of the blade can be completed. It can be seen that compared with the existing wind turbine blade anti-corrosion device, the wind turbine blade anti-corrosion device in this embodiment does not need to fix the anti-corrosion curtain 706 by bolts, but only needs to pull out the anti-corrosion curtain 706 and then stick the push plate 707 in the locking groove 708 to complete, which has the characteristics of convenient and quick installation. In addition, the wind turbine blade anti-corrosion device in this embodiment can also wrap different layers of anti-corrosion curtains 706 around the blades according to anti-corrosion requirements, thereby being able to adapt to diverse blade anti-corrosion requirements.

[0066] In a possible embodiment of the present application, another anti-corrosion component is provided. Figure 3 is another schematic diagram of an anti-corrosion component provided in an embodiment of the present application, such as Figure 3As shown, a rotating shaft 704 is provided inside the rolling drum 705 , and two ends of the rotating shaft 704 are respectively fixedly connected to two winding platforms 703 , and the winding platforms 703 are rotatably connected to the tank body of the storage tank 702 .

[0067] Specifically, push the pushing plate 707, the pushing plate 707 drives the anti-corrosion curtain 706, the anti-corrosion curtain 706 drives the rolling drum 705, the rolling drum 705 drives the rotating shaft 704, the rotating shaft 704 drives the winding platform 703, so that the anti-corrosion curtain 706 is wrapped around the wind turbine blades, and the pushing plate 707 is placed in the locking groove 708 to complete the fixation of the anti-corrosion curtain 706.

[0068] Considering that the protective cover of the existing wind turbine blade anti-corrosion device is easily eroded by rainwater due to long-term exposure, and the protective cover is prone to static electricity affecting the device, a possible embodiment of the present application provides an anti-corrosion curtain. Figure 4 Schematic diagram of the anti-corrosion curtain structure provided in the embodiment of the present application. Figure 4 As shown, the anti-corrosion curtain 706 includes an anti-corrosion layer 7063 , and the two sides of the anti-corrosion layer 7063 are respectively provided with a waterproof layer 7062 and an antistatic layer 7064 . The anti-corrosion layer 7063 , the waterproof layer 7062 , and the antistatic layer 7064 wrap the curtain body 7061 .

[0069] By arranging a waterproof layer 7062 and an antistatic layer 7064 on both sides of the anti-corrosion layer 7063, the anti-corrosion curtain 706 has three functions of anti-corrosion, anti-rainwater and anti-static, and has a stronger protection ability for the blades.

[0070] In a possible embodiment of the present application, another wind turbine blade anti-corrosion device is provided. Figure 5 Schematic diagram of another wind turbine blade anti-corrosion device provided in an embodiment of the present application, such as Figure 5 As shown, a first locking band 3 is provided on the side of each locking rod 2, a second locking band 5 is provided on the opposite side of each first locking band 3, the first locking band 3 is provided with a first locking portion 4, the second locking band 5 is provided with a second locking portion 6, and the first locking portion 4 cooperates with the second locking portion 6 to lock the first locking band 3 and the second locking band 5 with each other.

[0071] Considering that the wind force at high altitudes where the wind turbine blades are located is strong, in order to prevent the anti-corrosion curtain 706 from falling off, an auxiliary locking method of the first locking belt 3 and the second locking belt 5 is additionally provided in addition to the fixing method of the push plate 707 and the locking groove 708. Specifically, after the anti-corrosion curtain 706 is wrapped around the blade and the push plate 707 is inserted into the locking groove 708, the first locking belt 3 and the second locking belt 5 are locked, thereby fastening the anti-corrosion curtain 706 to prevent the wind force from pulling the push plate 707 out of the locking groove 708.

[0072] like Figure 5As shown, the first locking portion 4 is a plurality of fixing holes, and the second locking portion 6 is a locking head. The locking head cooperates with the first locking belt 3 so that after the first locking belt 3 passes through the locking head, the locking head locks the position of the fixing hole. Optionally, a locking tongue may be provided in the locking head. After the first locking belt 3 passes through the locking head, the locking tongue in the locking head passes through the fixing hole, thereby locking the position of the fixing hole. The purpose of providing a plurality of fixing holes is to adjust the locking tightness of the first locking belt 3 and the second locking belt 5 by locking different fixing holes.

[0073] It should be noted that the first locking belt 3 and the second locking belt 5 of this embodiment can be multiple, so as to enhance the locking effect of the anti-corrosion curtain 706. The first locking portion 4 and the second locking portion 6 are also not limited to Figure 5 The fixing hole and the lock head shown in the figure have a variety of optional structures. For example, the first locking portion 4 can be a tenon, and the second locking portion 6 can be a slot. The tenon can be inserted into the slot to complete the matching and locking of the first locking belt 3 and the second locking belt 5. When the first locking portion 4 is a tenon and the second locking portion 6 is a slot, the first locking belt 3 and the second locking belt 5 are locked conveniently and quickly.

[0074] In a possible embodiment of the present application, a wind turbine blade anti-corrosion device is provided. Figure 6 A schematic diagram of a wind turbine blade anti-corrosion device provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, a buffer device 8 is provided on the top surface of the storage platform 701. A buffer cushion 805 is provided on the top surface of the buffer device 8. During the actual installation process, the buffer device 8 faces the blade, thereby preventing the blade surface from being damaged by collision during the installation process.

[0075] Optionally, the buffer device 8 may further include a buffer platform 801 , a buffer groove 802 , a damping rod 803 , and a damping spring 804 . Figure 7 A schematic diagram of another buffer device structure provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, a plurality of buffer grooves 802 are provided on the buffer platform 801; a plurality of damping rods 803 are provided on the buffer cushion 805, and the plurality of damping rods 803 are inserted into the plurality of buffer grooves 802, and a damping spring 804 is sleeved between the damping rod 803 and the buffer groove 802. During the installation process of the wind turbine blade anti-corrosion device provided in the present application, the buffer cushion 805 faces the blade surface, and after the buffer cushion 805 contacts the blade surface, the blade compresses the buffer cushion 805, and the buffer cushion 805 drives the damping rod 803 and the damping spring 804, and the damping rod 803 is compressed in the buffer groove 802, and the damping spring 804 offsets the squeezing force, thereby avoiding collision damage to the blade surface.

[0076] The number of buffer slots 802, damping rods 803, and damping springs 804 can be three and arranged in a linear parallel manner to increase the force-bearing area. The number of buffer slots 802, damping rods 803, and damping springs 804 can also be multiple and arranged in a parallel array to further increase the force-bearing area.
