Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation blade clamping, and specifically to a wind power generation blade clamping device. Background Art

[0002] As an important component of a wind power generation system, a wind turbine generally includes components such as a wind wheel, a generator (including devices), a yaw device (tail fin), a tower, a speed limit safety mechanism, and an energy storage device. The wind wheel includes components such as blades, a hub, and reinforcement members. During the transportation and production of wind power generation blades, clamping devices are required to fix the blades.

[0003] A patent document with the publication number CN221291037U, a clamping device for wind power generation blades, places the connection end of the wind power generation blade inside the fixed block. By starting the telescopic pump, the clamping plate moves downward, so that the first fixing groove coincides with the upper end of the end of the wind power generation blade. Since the inner side of the second fixing groove is adapted to the blade of the wind power generator, the second fixing groove wraps the wind blade, thus completing the clamping and fixing of the wind power generation blade. At the same time, during transportation, the buffer pad can effectively prevent the wear caused by the collision between the wind blade and the fixing plate.

[0004] However, in the process of implementing the above technical solution, the following technical problems are found in the above technical solution:

[0005] The clamping device for wind power generation blades uses a telescopic pump to control the downward movement of the clamping plate. With the cooperation of the fixing groove and the wind power generation blade, the blade can be wrapped, thus realizing the clamping and fixing work of the blade. However, in actual application, due to different surface models and different curved surface radiances, it is difficult to use the same clamping device for clamping different wind power generation blades. Summary of the Invention

[0006] In order to overcome the deficiency that the existing clamping device for wind power generation blades is difficult to use the same clamping device for clamping different wind power generation blades due to different surface models and different curved surface radiances in the form of cooperation between the fixing groove and the wind power generation blade, the embodiment of the present application provides a wind power generation blade clamping device. By controlling the pressing plate to rotate around its hinge point with the seat plate, one end of the second threaded rod passes through the inside of the seat plate, and the locking member threaded on the outside of the second threaded rod supports at the bottom of the seat plate, the rubber pad on the pressing plate can be pressed on the surface of the wind power generation blade and supported by the rubber pad on the top of the seat plate. With the spring in a compressed state, the rubber pad can conform to the surface of the wind power generation blade, facilitating the clamping and fixing work of wind power generation blades with different curved surface radiances.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problems is as follows:

[0008] A wind power generation blade clamping device includes a pressing plate, a base plate, and a protection component. The base plate is hinged to the bottom of one end of the pressing plate;

[0009] There are two protection components, which are respectively assembled on the bottom of the pressing plate and the top of the base plate;

[0010] One end of the pressing plate away from the connection with the base plate is hingedly connected with a pull rod. One end of the pull rod is integrally formed with a second threaded rod, and the outside of the second threaded rod is threadedly connected with a locking member;

[0011] The two protection components face each other and both include rubber pads. A plurality of springs are provided between the rubber pad and the base plate, and between the rubber pad and the pressing plate;

[0012] Wherein, one end of the wind power generation blade is placed between the two rubber pads. The pressing plate rotates around its hinge point with the base plate, so that one end of the second threaded rod passes through the inside of the base plate and is supported by the locking member at the bottom of the base plate, thereby pressing the rubber pad on the pressing plate against the surface of the wind power generation blade, and making the spring compressed by the mutual force, so that the rubber pad fits the surface of the wind power generation blade.

[0013] In a possible implementation manner, an activity notch is opened inside one end of the base plate away from the connection with the pressing plate. Second straight cutting surfaces are processed on both sides of the second threaded rod; one of the second straight cutting surfaces is attached to the inner wall of one end of the activity notch close to the rubber pad, and the second threaded rod is movably connected inside the activity notch.

[0014] In a possible implementation manner, one end of the base plate away from the connection with the pressing plate is bent downward, and a stop bar is welded to the bottom surface of this end. The top of the locking member is located between the stop bar and the outwardly bent part of the base plate.

[0015] In a possible implementation manner, the locking member includes an internally threaded sleeve. One end of the internally threaded sleeve is integrally formed with a ball head. First straight cutting surfaces are processed on both sides of the internally threaded sleeve. The locking member is movably connected to the bottom surface of the base plate through the ball head.

[0016] In a possible implementation, both ends of the rubber pad are bent in the same direction. Multiple rubber seats are hot-melt formed on the surfaces of the two rubber pads facing the seat plate or the pressing plate. A metal seat is hingedly connected to the outside of the multiple rubber seats. A first support disc is fixedly connected to the part of the metal seat facing the pressing plate or the seat plate. A support rod is integrally formed on the surface of the first support disc. A first threaded rod is integrally formed at one end of the support rod. A nut is threadedly connected to the outside of the first threaded rod. Multiple cushion sleeves are welded to the opposite surfaces of the pressing plate and the seat plate; multiple springs are respectively sleeved on the outside of the multiple support rods, and the multiple first threaded rods respectively pass through the interiors of the multiple cushion sleeves, so that the nut supports at the end face of the cushion sleeve.

[0017] In a possible implementation, multiple external threaded sleeves are threadedly connected to the interiors of the pressing plate and the seat plate. A second support disc is integrally formed at one end of each of the multiple external threaded sleeves; the multiple external threaded sleeves correspond to the multiple springs one by one, and the springs support between the second support disc and the first support disc.

[0018] In a possible implementation, the support rod is slidably connected to the inside of the external threaded sleeve. The diameter of the first threaded rod is smaller than the diameter of the support rod, and the first threaded rod is movably connected to the inside of the external threaded sleeve.

[0019] In a possible implementation, an assembly bracket is welded to the outside of the seat plate near one end where it is connected to the pressing plate. The assembly bracket is L-shaped. After the assembly bracket is assembled and fixed, the seat plate is kept in a horizontal state.

[0020] In a possible implementation, two storage racks are welded to the top surface of the assembly bracket. Both of the two storage racks are V-shaped and parallel to the long side of the assembly bracket.

[0021] The beneficial effects of this application are as follows:

[0022] First, in this solution, by controlling the pressing plate to rotate around its hinge point with the seat plate, one end of the second threaded rod is passed through the inside of the seat plate, and the locking member threadedly connected to the outside of the second threaded rod supports at the bottom of the seat plate, so that the rubber pad on the pressing plate can be pressed on the surface of the wind power generation blade and supported by the rubber pad on the top of the seat plate. With the spring in a compressed state, the rubber pad can be made to fit the surface of the wind power generation blade, facilitating the clamping and fixing work of wind power generation blades with different curved surfaces.

[0023] Second, in this solution, by adjusting the external thread sleeve and the pressing plate, and the threaded connection between the external thread sleeve and the seat plate, the distance between the second support plate and the first support plate is controlled to control the initial compression degree of the spring. When the wind power generation blade is clamped by the rubber pads on the pressing plate and the seat plate, the stability of clamping the wind power generation blade by the seat plate and the pressing plate through the rubber pads can be ensured.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0031] Embodiment 1:

[0032] This embodiment introduces the specific structure of a wind power generation blade clamping device, specifically referring to Figures 1-4 as shown, including a pressing plate 7, a seat plate 6 hinged to the bottom of one end of the pressing plate 7, and two protection assemblies 8. One end of the pressing plate 7 away from the connection with the seat plate 6 is hingedly connected with a pull rod 9. One end of the pull rod 9 is integrally formed with a second threaded rod 10. The outside of the second threaded rod 10 is threadedly connected with a locking member 4. The two protection assemblies 8 are arranged facing each other, and each includes a rubber pad 801. A plurality of springs 808 are arranged between the rubber pad 801 and the seat plate 6, and between the rubber pad 801 and the pressing plate 7;

[0033] Among them, two protective components 8 are respectively assembled at the bottom of the pressing plate 7 and the top of the seat plate 6. When one end of the wind power blade is placed between two rubber pads 801 (the rubber pad 801 on the top of the seat plate 6), the pressing plate 7 can be controlled to rotate around its hinge point with the seat plate 6, so that the rubber pad 801 on the pressing plate 7 covers the surface of the wind power blade;

[0034] Immediately, one end of the second threaded rod 10 is passed through the inside of the seat plate 6, and the locking member 4 threadedly connected to the outside of the second threaded rod 10 is supported at the bottom of the seat plate 6, so that the rubber pad 801 on the pressing plate 7 can be pressed on the surface of the wind power blade. At this time, due to the interaction of forces, the spring 808 is in a compressed state, which can make the rubber pad 801 conform to the surface of the wind power generator blade under the influence of the compression of the spring 808 (when the rubber pad 801 conforms to the surface of the wind power blade, the metal seat 809 and (810 rotate relative to each other, and the rubber pad 801 can be stretched during the deformation process), so as to adapt to wind power blades with different curved surfaces;

[0035] Secondly, in order to prevent the second threaded rod 10 from interfering with the inner wall of the movable notch 5 due to the influence of the threads on the surface of the second threaded rod 10 during the movement inside one end of the seat plate 6, as Figure 1 shown, a movable notch 5 is opened inside one end of the seat plate 6 away from the connection with the pressing plate 7. Second straight cutting surfaces 11 are processed on both sides of the second threaded rod 10. By making one second straight cutting surface 11 fit with the inner wall of the end of the movable notch 5 close to the rubber pad 801, it can support the second threaded rod 10 to be movably connected inside the movable notch 5 without being affected by the threads and without affecting the threaded connection between the locking member 4 and the second threaded rod 10;

[0036] Furthermore, in order to prevent the locking member 4 from sliding on the bottom surface of the seat plate 6 when the pull rod 9 and the locking member 4 control the ends of the seat plate 6 and the pressing plate 7 away from the hinge point to approach each other, as Figure 1 and Figure 3 shown, one end of the seat plate 6 away from the connection with the pressing plate 7 is bent towards the bottom, and a stop bar 3 is welded and connected to the bottom surface of this end. By making the top of the locking member 4 located between the stop bar 3 and the part of the seat plate 6 bent outwards, after one end of the second threaded rod 10 is passed through the inside of the movable notch 5 and threadedly connected to the locking member 4, the locking member 4 can be stably supported between the stop bar 3 and the part of the seat plate 6 bent towards the bottom;

[0037] In some examples, the locking member 4 includes an internally threaded sleeve 402. A ball head 401 is integrally formed at one end of the internally threaded sleeve 402. First straight cutting surfaces 403 are processed on both sides of the internally threaded sleeve 402;

[0038] Among them, by movably connecting the locking member 4 to the bottom surface of the seat plate 6 by means of the ball head 401, when adjusting the threaded connection between the locking member 4 and the second threaded rod 10, the curved surface on the ball head 401 can be utilized to ensure smooth rotation of the locking member 4.

[0039] In the above design, one end of the wind power generation blade is placed between two rubber pads 801, the pressing plate 7 is controlled to rotate around its hinge point with the seat plate 6, so that the rubber pads 801 on the pressing plate 7 cover the surface of the wind power generation blade, one end of the second threaded rod 10 passes through the inside of the seat plate 6, and the locking member 4 threaded outside the second threaded rod 10 supports on the bottom of the seat plate 6 (and the movement of the ball head 401 is restricted by the stop bar 3 on the bottom surface of the seat plate 6, but rotation is not affected), the rubber pads 801 on the pressing plate 7 can be pressed on the surface of the wind power generation blade. At this time, due to the interaction of forces, the spring 808 is in a compressed state, which can make the rubber pads 801 conform to the surface of the wind power generation blade, so as to adapt to wind power generation blades with different curved surfaces.

[0040] Embodiment 2:

[0041] Based on Embodiment 1, this embodiment introduces the specific structure of the protection component 8, such as Figure 4 and Figure 5 As shown, both ends of the rubber pad 801 are bent in the same direction. Multiple rubber seats 810 are hot-melt formed on the surfaces of the two rubber pads 801 facing the seat plate 6 or the pressing plate 7. Multiple metal seats 809 are hingedly connected to the outside of the multiple rubber seats 810. A first support disk 806 is fixedly connected to the part of the metal seat 809 facing the pressing plate 7 or the seat plate 6. A support rod 802 is integrally formed on the surface of the first support disk 806. A first threaded rod 803 is integrally formed at one end of the support rod 802. A nut 804 is threadedly connected to the outside of the first threaded rod 803. Multiple bushings 805 are welded to the opposite surfaces of the pressing plate 7 and the seat plate 6;

[0042] Among them, by sleeving multiple springs 808 on the outside of multiple support rods 802 respectively, when the multiple first threaded rods 803 pass through the inside of the multiple bushings 805 respectively and the nut 804 supports at the end face of the bushing 805, the springs 808 can be stably located between the rubber pad 801 and the pressing plate 7, and between the rubber pad 801 and the seat plate 6, and perform compression and relaxation work;

[0043] Secondly, in order to facilitate adjusting the initial compression degree of the springs 808 at different positions to ensure the stability of the seat plate 6 and the pressing plate 7 clamping the wind power generation blade (in the state of clamping the wind power generation blade, the multiple springs 808 can maintain the same compression state), such as Figure 5As shown, a plurality of external thread sleeves 811 are internally threadedly connected to the pressing plate 7 and the seat plate 6. One end of each of the plurality of external thread sleeves 811 is integrally formed with a second support plate 807. By making the plurality of external thread sleeves 811 correspond to the plurality of springs 808 one by one, and the springs 808 are supported between the second support plate 807 and the first support plate 806. When adjusting the threaded connection between the external thread sleeve 811 and the pressing plate 7, the external thread sleeve 811 can drive the second support plate 807 to move, controlling the compression degree of the spring 808;

[0044] At the same time, by making the diameter of the first threaded rod 803 smaller than the diameter of the support rod 802, the first threaded rod 803 can be movably connected inside the external thread sleeve 811, without affecting the sliding of the support rod 802 inside the external thread sleeve 811;

[0045] In some examples, an assembly bracket 1 is welded to the outside of one end of the seat plate 6 close to its connection with the pressing plate 7. Two storage racks 2 are welded to the top surface of the assembly bracket 1;

[0046] Among them, by making the assembly bracket 1 in an L shape, when the assembly bracket 1 is assembled and fixed, the seat plate 6 can be supported in a horizontal state, facilitating the erection work of the wind power generation blade;

[0047] At the same time, by making both of the two storage racks 2 in a V shape and parallel to the long side of the assembly bracket 1, tools such as wrenches can be stored by means of the storage racks 2.

[0048] The above design is through arranging the support rod 802 inside the spring 808, using the external thread sleeve 811 threadedly connected to the inside of the seat plate 6 or the pressing plate 7. During the process of the external thread sleeve 811 supporting the sliding of the support rod 802, with the nut 804 externally threadedly connected to the first threaded rod 803 supported at the end face of the cushion sleeve 805, the threaded connection between the external thread sleeve 811 and the pressing plate 7 (or the seat plate 6) can be adjusted, and the initial compression degree of the spring 808 can be controlled by controlling the distance between the second support plate 807 and the first support plate 806. When clamping the wind power generation blade with the rubber pads 801 on the pressing plate 7 and the seat plate 6, the stability of clamping the wind power generation blade by the seat plate 6 and the pressing plate 7 through the rubber pads 801 can be ensured, and the compression degrees of the plurality of springs 808 can be made basically the same.

[0049] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
