Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wind power blade deicing, in particular to a wind power blade ice removal device. BACKGROUND

[0002] The wind power blade is an important component of the wind turbine, which mainly functions to convert wind energy into mechanical energy to drive the generator to generate electricity. Generally speaking, when the wind blows through the blade, the blade will generate lift and start to rotate, converting wind energy into mechanical energy. This rotational motion converts mechanical energy into electricity through the shaft, thereby enabling the generator to generate electricity. This means that the wind power blade, as one of the core components of the wind power system, plays a crucial role in wind energy utilization. However, in cold conditions, the surface of the wind power blade often has icing problems, which affects the wind energy capture efficiency of the blade, thereby increasing the load of the blade and reducing the performance of the wind turbine, and may cause equipment damage or accidents.

[0003] In the related art wind power blade deicing process, heating elements are generally installed inside or on the surface of the blade to melt or prevent ice formation through heating. This method not only requires energy supply, but also requires a reasonable temperature control system to prevent overheating or energy waste. Although there are devices in the related art that generate mechanical vibrations to prevent ice formation or remove ice by installing vibration devices on the surface of the blade, the devices in the related art still have the following problems when deicing:

[0004] 1. Even if the heating system and the vibration device are used together to deice the surface of the blade on a large scale, there will still be residual water on the wind power blade, which will quickly freeze into ice in extreme weather, covering the surface of the blade and increasing the load of the blade.

[0005] 2. To prevent ice, a snow brush is generally installed on the surface of the blade to remove ice. The snow brush is usually fixed in one position and relies on the rotation of the blade to move relative to the snow brush to scrape the ice off the surface of the blade. However, there will still be residual ice in the gaps of the snow brush, and the ice removal is not thorough enough.

[0006] 3. The overall volume of the wind power blade is large, and the snow brush will be worn out due to constant friction with the blade during long-term operation. If the new snow brush is not replaced in time, it will affect the ice removal effect. SUMMARY

[0045] The embodiment of the present application has the following advantages:

[0046] In the embodiment of the present application, a wind power blade ice fragment removing device is designed, which at least comprises: a blade body; a support column connected with the inside of the blade body; an adjusting mechanism arranged above the support column; a connecting rod connected with the adjusting mechanism and arranged above the adjusting mechanism; a deicing mechanism slidingly connected with the connecting rod; and a guide wheel arranged at the top end of the connecting rod, which has the following beneficial effects:

[0047] 1. The wind power blade ice fragment removing device is provided with a brush and a surface-adhering blade body, when the blade body rotates through the brush, the blade body and the brush are rubbed with each other, so that the ice fragments on the surface of the blade body are removed, and the accumulation of the ice fragments on the surface of the blade body is avoided, and the working effect is affected.

[0050] 4. The wind power blade ice fragment removal device drives the rotation of the rotating column through the second motor. Since the first rotating rod and the second rotating rod are located at both ends of the rotating column, the rotating column drives the simultaneous rotation of the first rotating rod and the second rotating rod when rotating. The first rotating rod and the second rotating rod always remain parallel, controlling the movement direction of the first pull rope and the second pull rope. The first pull rope and the second pull rope cooperate with each other when moving, thereby increasing the stability of the structure.

[0051] 5. The wind power blade ice fragment removal device drives the rotation of the third gear through the third motor, which can further drive the rack and the brush plate to slide back and forth along the limiting block. The rack and the brush plate are actuated to slide along the limiting block. When the entire brush plate is separated from the limiting block, a new brush plate and brush can be replaced. The third motor is used to replace the traditional manual operation, which can save manpower. BRIEF DESCRIPTION OF DRAWINGS

[0094] Specifically, through the above structure, the wind power blade ice removal device provided by the embodiment can be combined with the surface of the blade body through the brush, when the blade body itself rotates through the brush, the ice on the surface of the blade body can be removed through mutual friction with the brush, avoiding the accumulation of ice on the surface of the blade body, affecting the working effect;

[0095] Further, the wind power blade ice fragment removing device provided by the embodiment can adjust the inclination angle of the whole ice removing mechanism through the adjusting mechanism, so that the brush is more attached to the surface of the blade body, and the ice fragment removing efficiency is improved. When the first motor drives the rotation of the rotating disc, the rotating disc drives the synchronous rotation of the sliding block, the sliding block slides along the fixed frame, and the fixed frame slowly rotates along the support column, so that the brush is more attached to the blade body, and when not in use, the ice removing mechanism can be adjusted to be parallel to the blade body, so that the contact area of the brush and the blade body is reduced, and the mutual friction is avoided to affect the rotation effect of the blade body.

The first rotating rod and the second rotating rod always remain parallel to control the movement direction of the first pull rope and the second pull rope. When the first pull rope and the second pull rope move, they can cooperate with each other to increase the stability of the structure.

[0098] Further, the wind power blade ice fragment removing device provided by the embodiment can drive the rotation of the third gear through the third motor, and can further drive the reciprocating sliding of the rack and the brush plate along the limiting block. When the whole brush plate is separated from the limiting block, a new brush plate and brush can be replaced.

It should be noted that the two sets of wind power blade ice fragment removing assemblies are arranged on the front face and the back face of the blade body 1 respectively, the deicing mechanism 5 can be used to simultaneously remove ice fragments on both sides of the blade body 1 through friction, and the adjusting mechanism 3 can be used to adjust the inclination angle of the entire deicing mechanism 5, so that the brush 507 is more closely attached to the surface of the blade body 1, thereby improving the removal efficiency of the ice fragments. When not in use, the deicing mechanism 5 can be adjusted to be parallel to the blade body 1, thereby reducing the contact area between the brush 507 and the blade body 1 and avoiding mutual friction to affect the rotation effect of the blade body 1.

[0106] In actual application, the first gear 3010 and the second gear 3011 can be arranged in meshing transmission structure, and the second gear 3011 can rotate through the second motor 3012; it should be noted that after the second motor 3012 is started, the second gear 3011 can be driven to rotate, and due to the meshing transmission between the first gear 3010 and the second gear 3011, the transmission force is large and the precision is higher.

[0107] In some embodiments of the present application, the first rotating rod (306) and the second rotating rod (308) are arranged in parallel structure.

[0108] In specific implementation, the first rotating rod 306 and the second rotating rod 308 can be arranged in parallel structure; it should be noted that since the first rotating rod 306 and the second rotating rod 308 are respectively located at two ends of the rotating column 305, when the rotating column 305 rotates, the first rotating rod 306 and the second rotating rod 308 can be driven to rotate at the same time, the first rotating rod 306 and the second rotating rod 308 always maintain parallel, can control the movement direction of the first pull rope 307 and the second pull rope 309, so that the first pull rope 307 and the second pull rope 309 can cooperate with each other when moving, and the stability of the device structure can be increased.

[0109] In some embodiments of the present application, the rack (503) and the third gear (504) are arranged in meshing transmission structure, and the third motor (505) is used to control the third gear (504) to rotate.

[0110] In actual application, the rack 503 and the third gear 504 can be arranged as a meshing transmission structure, and the third gear 504 can constitute a rotary motion through the third motor 505; it should be noted that the third gear 504 drives the rack 503 and the brush plate 502 to slide back and forth along the limiting block 501, and since the third motor 505 is adopted for driving, the traditional manual operation can be replaced, and manpower can be saved.

[0111] In some embodiments of the present application, the fixing frame (301) is arranged on the upper surface of the support column (2), and the fixing frame (301) is rotationally connected with the support column (2).

[0112] In actual application, the fixing frame 301 can be arranged on the upper surface of the support column 2, and the fixing frame 301 and the support column 2 can be rotationally connected; it should be noted that the support column 2 is penetrated by a rotating shaft, the top of the rotating shaft is connected with the fixing frame 301, through the connection of the rotating shaft, the fixing frame 301 can rotate along the support column 2, and by adjusting the inclination angle of the fixing frame 301, the mutual adhesion between the brush 507 of the deicing mechanism 5 and the blade body 1 can be controlled.

[0113] In some embodiments of the present application, the first motor (304) is used to control the rotating motion of the rotating disc (303).

[0114] In specific implementation, the rotating disc 303 can constitute a rotary motion through the first motor 304; it should be noted that the first motor 304 can be a large-power motor with slow rotating speed, through the driving of the first motor 304, the rotating motion of the rotating disc 303 is realized, so that when the rotating disc 303 drives the synchronous rotation of the sliding block 302, the sliding block 302 will slide along the fixing frame 301, and the fixing frame 301 can be further driven to rotate slowly along the support column 2.

[0115] In some embodiments of the present application, the brush (507) is attached to the surface of the blade body (1), and the material of the brush (507) is nylon material.

[0116] In actual application, as shown in Figure 5 the brush 507 can be attached to the surface of the blade body 1, and the brush 507 can be made of nylon material; it should be noted that through the attachment of the brush 507 and the surface of the blade body 1, when the blade body 1 rotates by itself through the brush 507, the blade body 1 can be rubbed with the brush 507 to remove the broken ice, and the use of nylon material not only has lower cost, but also will not scratch the coating on the surface of the blade body 1.

[0117] On the basis of the above, it needs to be emphasized that the wind power blade ice removal device can first heat the blade body 1 through the heating system inside the blade body 1 itself to melt the large-area ice on the surface of the blade body 1, and then start the first motor 304 of the adjusting mechanism 3 to drive the rotating disc 303 to rotate. When the rotating disc 303 rotates clockwise, the sliding block 302 can drive the fixed frame 301 to tilt inward, further driving the entire ice removal mechanism 5 to tilt inward. When the angle is tilted to a certain angle, the brush 507 is attached to the surface of the blade body 1 and the wind blows through the blade body 1, the blade body 1 itself starts to rotate and continuously rubs with the brush 507 to remove the ice. At this time, the first motor 304 can be turned off, the second motor 3012 is started to drive the second gear 3011 and the first gear 3010 to rotate, further driving the rotating column 305 to rotate, which drives the first rotating rod 306 and the second rotating rod 308 to rotate at the same time. The first rotating rod 306 and the second rotating rod 308 always keep parallel, control the movement direction of the first pull rope 307 and the second pull rope 309. When the first pull rope 307 moves upward, the second pull rope 309 is retracted downward. When the second pull rope 309 moves upward, the first pull rope 307 is retracted downward. The second pull rope 309 pulls the uppermost ice removal mechanism 5 to drive the remaining ice removal mechanisms 5 to slide upward synchronously. The first pull rope 307 pulls the lowermost ice removal mechanism 5 to drive the remaining ice removal mechanisms 5 to slide downward synchronously. Under the cooperation of the first pull rope 307 and the second pull rope 309, the ice removal mechanism 5 will move up and down reciprocatingly every time the blade body 1 passes through the brush 507 to completely remove the ice. When the brush 507 needs to be replaced, the third motor 505 can be started. When the third motor 505 rotates, the rack 503 and the brush plate 502 slide along the limiting block 501. When the entire brush plate 502 is separated from the limiting block 501, the new brush plate 502 and the brush 507 can be replaced.

[0118] The present application provides a wind power blade ice removal device, which has the following advantages:

[0119] 1. The wind power blade ice removal device can remove the ice on the surface of the blade body by the attachment of the brush and the surface of the blade body, and the mutual friction between the brush and the blade body when the blade body rotates, which can avoid the accumulation of ice on the surface of the blade body and affect the working effect.

[0120] 2. The wind power blade ice fragment removing device can adjust the inclination angle of the entire ice removing mechanism through the adjusting mechanism, so that the brush is more closely attached to the surface of the blade body, and the ice fragment removing efficiency is improved. When the first motor drives the rotation of the rotating disc, the rotating disc drives the synchronous rotation of the sliding block, and the sliding block slides along the fixed frame, further driving the fixed frame to slowly rotate along the support column, so that the brush is more closely attached to the blade body. When not in use, the ice removing mechanism can be adjusted to be parallel to the blade body, so as to reduce the contact area of the brush and the blade body, and avoid mutual friction affecting the rotation effect of the blade body.

[0121] 3. The wind power blade ice fragment removing device can not only pull the uppermost ice removing mechanism through the second pull rope to drive the synchronous upward sliding of the remaining ice removing mechanisms, but also pull the lowermost ice removing mechanism through the first pull rope to drive the synchronous downward sliding of the remaining ice removing mechanisms. Under the cooperation of the first pull rope and the second pull rope, the ice removing mechanism can reciprocate up and down, so as to control the brush to slide and rub the surface of the blade body up and down to completely remove the ice fragments.

[0122] 4. The wind power blade ice fragment removing device drives the rotation of the rotating column through the second motor. Since the first rotating rod and the second rotating rod are respectively located at both ends of the rotating column, the rotating column drives the synchronous rotation of the first rotating rod and the second rotating rod when rotating. The first rotating rod and the second rotating rod always remain parallel, controlling the movement direction of the first pull rope and the second pull rope. The first pull rope and the second pull rope can increase the stability of the structure when moving in cooperation.

[0123] 5. The wind power blade ice fragment removing device drives the rotation of the third gear through the third motor, which can further drive the rack and the brush plate to slide back and forth along the limiting block. When the entire brush plate is separated from the limiting block, a new brush plate and brush can be replaced. The third motor is used to replace the traditional manual operation, which can save manpower.
