Description

Technical Field

[0001] This invention relates to the field of wind power generation, and more particularly to a wind turbine with blade protection function. Background Technology

[0002] In areas rich in wind resources, a large number of wind turbines are usually installed to make full use of these natural resources. However, these areas are also frequent typhoon hotspots. Typhoons bring not only strong winds, but also complex wind direction changes and huge impacts. When a typhoon passes, these extreme weather conditions pose a severe challenge to wind turbines, especially to the blades. Due to the extremely high wind speeds and variable wind directions of typhoons, they may generate loads that exceed the design capacity of wind turbines, causing blade breakage and even damage to the entire generator. This situation will not only cause damage to the equipment itself, but also result in significant economic losses, affecting the normal operation and energy output of the wind farm.

The connecting ring 6 is fixedly connected to six ropes I7, and the other end of each rope I7 passes through an adjacent fixed frame 5 and is connected to an adjacent rotating plate 4.

[0036] It also includes a bidirectional electric push rod I 201 and a support plate 202; the generator rod 1 is fixedly connected to the bidirectional electric push rod I 201; all telescopic ends of the bidirectional electric push rod I 201 are fixedly connected to a support plate 202, and the support plate 202 is slidably connected to the generator rod 1; and the support plate 202 is located below the generator set 10.

[0037] The upper side of the support plate 202 is provided with several ball bearings to reduce the friction between the connecting ring 6 and the support plate 202, thereby reducing the wear between the support plate 202 and the connecting ring 6 when the connecting ring 6 and the rotating frame 2 rotate.

[0038] It also includes a bidirectional electric push rod II 203 and a sliding plate 204; the generator rod 1 is fixedly connected to the bidirectional electric push rod II 203; all telescopic ends of the bidirectional electric push rod II 203 are fixedly connected to a sliding plate 204, and the sliding plate 204 is slidably connected to the generator rod 1, and the sliding plate 204 is located above the generator set 10.

[0039] The support plate 202 is provided with groove I 20201; the sliding plate 204 is provided with groove II 20401, and grooves I 20201 and II 20401 cooperate with the connecting block 107.

[0040] It also includes a spring telescopic rod 211 and a limiting plate 212; each sliding plate 204 is fixedly connected to two spring telescopic rods 211; all the spring telescopic rods 211 are fixedly connected to the limiting plate 212; the fixing ring 8 is provided with a limiting groove 8002, and the limiting groove 8002 is engaged with the limiting plate 212.

[0041] It also includes a support ring 401; the lower end of the generator pole 1 is fixed with a support ring 401.

[0042] The working steps of the above embodiment are as follows: First, the operator installs the invention at the windward power generation position. Then, the motor I106 drives the gear II105 to rotate. Since gear II105 meshes with gear I104, gear II105 drives gear I104, rotating rod I101, and winding wheel I102 to rotate, thereby winding up rope II103. Rope II103 pulls the corresponding connecting block 107 to move upward. In the initial state, the connecting block 107 is in the mating groove I6001 and mating groove II8001 respectively. Thus, the connecting block 107 pulls the fixing ring 8, rotating frame 2, fixing plate 3, rotating plate 4, and all connected parts upward. At the same time, the motor II116 drives the gear IV115 to rotate. Since gear IV... 115 meshes with gear Ⅲ114, causing gear Ⅳ115 to drive gear Ⅲ114, rotating rod Ⅱ111, and winding wheel Ⅱ112 to rotate, thereby loosening rope Ⅲ113. This prevents rope Ⅲ113 from tightening the corresponding connecting block 107, and prevents connecting block 107 from pulling on connecting ring 6, thus avoiding interference with the upward movement of fixing ring 8, rotating frame 2, fixing plate 3, rotating plate 4, and all connected parts. When rotating frame 2 moves upward to contact generator set 10, the protruding part 10001 will insert into the groove part 2001 of rotating frame 2, allowing rotating frame 2 to continue moving on generator set 10. This allows subsequent rotating frame 2 to drive generator set 10 to rotate. Then, when connecting ring 6 moves above support plate 202, motor Ⅰ 106 and motor II 116 stop rotating, so that rope II 103 no longer pulls the rotating frame 2, and rope III 113 no longer loosens, no longer pulling the rotating frame 2 to move. Then, control the bidirectional electric push rod I 201 to push the two support plates 202 to move in opposite directions. When the groove I 20201 moves to contact the lower connecting block 107, it will push the lower connecting block 107 to move away from the connecting ring 6, so that the connecting block 107 disengages from the mating groove I 6001. Then, the bidirectional electric push rod I 201 stops pushing, and at the same time, the support plate 202 will also move below the connecting ring 6. It should be noted that at this time, the upper connecting block 107 will also be aligned with the sliding plate 204. Therefore, during the movement of the support plate 202, control the bidirectional electric push rod II 102 to move in opposite directions. 203 pushes the sliding plate 204 to move in opposite directions. When the groove II 20401 moves to contact the upper connecting block 107, it will push the upper connecting block 107 to move away from the fixed ring 8, so that the connecting block 107 is disengaged from the mating groove II 8001. The bidirectional electric push rod II 203 stops pushing. Then the connecting block 107 no longer limits the fixed ring 8 and the connecting ring 6. Since the support plate 202 moves to the bottom of the connecting ring 6 at this time, it will support the connecting ring 6 through the support plate 202, so that the connecting ring 6, the rotating frame 2 and all its connected parts will not fall down, and the subsequent rotation of the connecting ring 6 and the fixed ring 8 will not affect the connecting block 107, thus not affecting the rope II 103 and the rope III 113.

[0043] It should be noted that the connecting block 107 is a magnet, and the rotating frame 2, connecting ring 6, support plate 202, and sliding plate 204 are all made of magnetic metal. Therefore, during the upward movement of the fixing ring 8 and connecting ring 6, the connecting block 107 will magnetically hold the mating groove I 6001 and mating groove II 8001, preventing the wind from blowing the rope II 103 and rope III 113 during the upward movement, which would cause the connecting block 107 to detach from the mating groove I 6001 and mating groove II 8001. After the support plate 202 and sliding plate 204 push the connecting block 107 to detach from the rotating frame 2 and connecting ring 6, the connecting block 107 will also magnetically attach to the groove I 20201 and groove II 20401, preventing the subsequent wind from blowing the rope II 103 and rope III 113, which would cause the connecting block 107 to detach from the groove I 20201 and groove II 20401.

[0044] When the wind blows, it will move the rotating plate 4. In the initial state, the limiting block 9 is inserted into the rotating plate 4, preventing the rotating plate 4 from rotating relative to the connecting ring 6. The connecting ring 6 is slidably connected to the rotating frame 2 through the connecting rod, preventing the connecting ring 6 from rotating relative to the rotating frame 2, the fixed plate 3, and the fixed frame 5. The fixed plate 3, the rotating plate 4, and the fixed frame 5 will also be unable to rotate relative to each other. Therefore, after the rotating plate 4 is blown, it will drive the fixed plate 3, the rotating frame 2, and all the parts connected to them to rotate. The rotating frame 2 will drive the generator set 10 to rotate, thereby generating electricity through the rotation of the generator set 10 and completing the normal power generation work.

[0045] Before the typhoon arrives, the bidirectional electric push rod II 203 continues to push the sliding plate 204 to move in opposite directions. The sliding plate 204 drives the spring telescopic rod 211 and the limiting plate 212 to move in opposite directions. When the limiting plate 212 contacts the fixed ring 8, the limiting plate 212 can no longer move. After the sliding plate 204 continues to move, the spring telescopic rod 211 is compressed, and the bidirectional electric push rod II 203 stops pushing. Then, when the fixed ring 8 rotates to the limiting groove 8002 and aligns with the limiting plate 212, the spring telescopic rod 211 will push the limiting plate 212 into the limiting groove 8002, thereby limiting the fixed ring 8 through the limiting plate 212, preventing the fixed ring 8 and the rotating frame 2 from continuing to rotate. At this time, the mating groove I 6001 and the mating groove II 8001 will realign with the connecting block 107. Then, the bidirectional electric push rod I 201 first pulls the support plate 202 to move in opposite directions, and the connecting block 1 below is moved by magnetic force. 07 moves towards the mating groove I 6001. When the lower connecting block 107 re-enters the mating groove I 6001, the bidirectional electric push rod I 201 stops pushing, so that the mating groove I 6001 and the groove I 20201 are in an overlapping state, thereby limiting the connecting ring 6 through the connecting block 107. Then, the bidirectional electric push rod II 203 is controlled to pull the sliding plate 204 to move towards each other. The upper connecting block 107 enters the mating groove II 8001 through magnetic force, and the limiting plate 212 is disengaged from the limiting groove 8002. However, since the connecting ring 6 is limited by the lower connecting block 107 at this time, the rotating frame 2 still cannot rotate. Then, the bidirectional electric push rod I 201 pulls the support plate 202 to move towards each other, so that the support plate 202 is fully inserted into the generator rod 1, and the lower connecting block 107 is disengaged from the groove I 20201. At this time, the support plate 202 will no longer support the connecting ring 6.

[0046] When the support plate 202 no longer supports the connecting ring 6, the motor II 116 is first reversed, causing the winding wheel II 112 to wind the rope III 113. This pulls the connecting ring 6, rope I 7, and limiting block 9 downwards via the connecting block 107 below. Once the limiting block 9 moves downwards and disengages from the rotating plate 4, it no longer limits the rotating plate 4, allowing it to rotate around the fixed plate 3. Simultaneously, as the rope I 7 moves downwards, it pulls the rotating plate 4 towards the corresponding fixed frame 5. The torsion spring between the rotating plate 4 and the fixed plate 3 is compressed. When the rotating plate 4 rotates to fit against the fixed frame 5, the rope I 7 can no longer pull the rotating plate 4. At this point, all the rotating plates 4 will combine to form a ring shape, resembling... Figure 12 As shown, when a typhoon subsequently forms, since all the rotating plates 4 are combined into a ring shape, the typhoon's airflow will flow along the surface of the rotating plates 4, reducing the direct impact of the typhoon on the rotating plates 4 and effectively protecting the rotating plates 4 from damage by the typhoon.

[0047] Based on the above work, the control motor I106 starts to reverse, causing the winding wheel I102 to loosen the rope II103, so that the upper connecting block 107 no longer tightens the fixing ring 8, allowing the connecting ring 6 to pull the rotating frame 2 downward, and keeping the rope I7 taut at all times, thus keeping the rotating plate 4 in a circular shape. When the connecting ring 6 moves downward to contact the support ring 401, the motors I106 and II116 stop rotating, the rotating frame 2 stops moving, and the rotating frame 2 and rotating plate 4 move to the lower end of the generator pole 1. This avoids the problem that during typhoons, the diameter of the circular shape formed by the rotating plate 4 is larger than the diameter of the generator pole 1, and the typhoon will generate thrust when it blows over the rotating plate 4. Since the rotating frame 2 and rotating plate 4 are at the upper end of the generator pole 1, they will exert a large thrust on the generator pole 1, which could easily cause the generator pole 1 to collapse.

[0048] After the typhoon passes, first control motor II116 to rotate forward, causing reel II112 to loosen rope III113. Then, connecting ring 6 and rope I7 will no longer be pulled. The torsion spring between rotating plate 4 and fixed plate 3 will drive rotating plate 4 to reset, thereby pulling connecting ring 6 and rope I7 upward. At this time, there will be a distance between connecting ring 6 and support ring 401. Connecting ring 6 is slidably connected to rotating frame 2 via connecting rod, preventing relative rotation between the connecting ring 6 and rotating frame 2. This ensures that after rotating plate 4 resets, the insertion port on rotating plate 4 aligns with limit block 9. After rotating plate 4 resets, motor II116 stops rotating, then control motor I106 to quickly reverse, rapidly loosening rope II103. Subsequently, rotating frame 2 and rotating plate 4 fall downwards due to gravity, as shown in the image. Figure 13 As shown, the connecting ring 6 will be below the rotating frame 2. Therefore, after the connecting ring 6 falls onto the support ring 401, the rotating frame 2 and the rotating plate 4 will squeeze the connecting ring 6 and the limiting block 9, causing the limiting block 9 to re-insert into the rotating plate 4 and re-limit the rotating plate 4. Then, the motors I 106 and II 116 are controlled to rotate synchronously, causing the winding wheel I 102 to wind up and the winding wheel II 112 to unwind, pulling the rotating frame 2 and the rotating plate 4 upward to reset, thereby continuing the power generation work.

[0049] Example 2

[0050] Based on Example 1, such as Figure 6 , Figure 8 and Figure 10 As shown, it also includes a protective ring 301 and ropes IV 302; two ropes IV 302 are fixedly connected to the upper end of the generator pole 1; the other end of all the ropes IV 302 are fixedly connected to the protective ring 301, which shields the generator set 10 and protects the generator set 10.

[0051] It also includes support blocks 303 and pressing blocks 304; the fixing ring 8 is fixedly connected to several support blocks 303; each sliding plate 204 is fixedly connected to two pressing blocks 304.

[0052] The working steps of the above embodiment are as follows: After the rotating frame 2 and the rotating plate 4 move downward, the generator set 10 will be fully exposed. When a typhoon strikes, strong winds will carry a large amount of debris, and these flying objects may hit the generator set 10, thereby causing damage to it. In the initial state, the protective ring 301 is above the pressing block 304 and is supported by the pressing block 304. Before the rotating frame 2 and the rotating plate 4 move downward, when the sliding plate 204 moves towards each other and drives the connecting block 107 above into the mating groove II 8001, the sliding plate 204 will drive the pressing block 304 to move towards each other. Subsequently, the sliding plate 204 and the pressing block 304 will move to the protective ring 301. Inside ring 301, the squeezing block 304 no longer supports the protective ring 301. Subsequently, the protective ring 301 falls onto the fixed plate 3 and the rotating plate 4. Therefore, when the rotating frame 2 and the rotating plate 4 move downward, the protective ring 301 will also lose its support and move downward. When the protective ring 301 moves to be aligned with the generator set 10, the rope IV 302 will be taut, and the protective ring 301 will not be able to continue falling. Thus, the protective ring 301 shields the generator set 10, protecting it from damage caused by a large number of objects being blown up during typhoons.

[0053] When the rotating frame 2 and rotating plate 4 move upward to reset, the fixed ring 8 will drive the support block 303 to move upward. The support block 303 will push the protective ring 301 upward. When the rotating frame 2 and rotating plate 4 move upward to reset, the support block 303 will push the protective ring 301 to move until the lower side of the protective ring 301 is aligned with the upper side of the sliding plate 204. Then, when the upper connecting block 107 is pushed out of the mating groove II 8001 by moving in opposite directions from the sliding plate 204, the sliding plate 204 will drive the pressing block 304 to move in opposite directions. The pressing block 304 will press the protective ring 301, causing the protective ring 301 to move further upward. The protective ring 301 is moved above the pressing block 304, and the pressing block 304 supports the protective ring 301, separating the protective ring 301 from the support block 303. At the same time, after the connecting block 107 above is pushed out of the mating groove II 8001, the rotating frame 2 and the rotating plate 4 will fall down until the connecting ring 6 contacts the support plate 202, causing the support block 303 to move below the sliding plate 204, preventing the sliding plate 204 from blocking the rotation of the support block 303. Thus, when the fixing ring 8 and the support block 303 rotate subsequently, the problem of wear on the protective ring 301 due to contact between the protective ring 301 and the support block 303 is avoided.

[0054] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
