Description

Technical Field

[0001] The present application belongs to the technical field of wind power generation, and in particular relates to a bolt and nut matching assembly for wind power generation. Background Art

[0002] The principle of wind power generation is to use wind force to drive the wind turbine blades to rotate. When the wind blows towards the blades, the wind wheel is driven to rotate, and the wind energy is converted into kinetic energy, which in turn drives the generator to generate electricity. Wind power generation cannot be separated from the presence of bolts during use. Bolts are a commonly used fastener and are widely used in various mechanical and electrical equipment. For ordinary applications where there are no particularly strict requirements for anti-loosening properties, an ordinary fastening assembly consisting of a bolt, a nut and a gasket can be used.

[0003] At present, when the existing bolt and nut assemblies are in use, it is easy for the nuts to loosen due to the shaking caused by the operation of the wind turbine. Therefore, the staff is required to regularly inspect the bolts and nuts installed on the wind turbine, which will cause certain inconveniences.

[0004] To this end, we propose a bolt and nut matching assembly for wind power to solve the above problems. Utility Model Content

[0008] Preferably, a hexagonal cap is fixedly connected to the top of the circular column, and a cross groove is formed on the upper surface of the hexagonal cap.

[0009] Preferably, a threaded column is fixedly connected to the bottom end of the circular column, a nut is threadedly connected to the outer surface of the threaded column, and the upper surface of the nut is fixedly connected to the bottom surface of the hexagonal ring.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A bolt and nut matching assembly for wind power includes a circular column 1, a hexagonal ring 4 is arranged on the outer side of the circular column 1, a sliding groove 12 is opened on the upper surface of the hexagonal ring 4, a hexagonal cap 5 is fixedly connected to the top of the circular column 1, and a cross groove 6 is opened on the upper surface of the hexagonal cap 5. By providing the hexagonal cap 5 and the cross groove 6, a tool can be used to extend into the interior of the cross groove 6 to apply rotational power to the hexagonal cap 5.

[0022] The internal sliding connection of the sliding groove 12 is a limited block 11, and the upper surface of the limit block 11 is fixedly connected to two connecting plates 16, and the interior of each connecting plate 16 is slidably connected to a limited column 13, and the bottom end of the circular column 1 is fixedly connected to a threaded column 7, and the outer surface of the threaded column 7 is threadedly connected to a nut 3, and the upper surface of the nut 3 is fixedly connected to the bottom surface of the hexagonal ring 4. By providing the threaded column 7 and the nut 3, the threaded connection relationship between the nut 3 and the threaded column 7 can drive the device indirectly connected above the nut 3 to contact the bottom of the component to be fastened, thereby achieving the purpose of fastening.

[0023] The outer surface of each limit column 13 is fixedly connected to a rectangular plate 15, and the sides of the two connecting plates 16 that are close to each other are fixedly connected to two force springs 14, and the sides of the two rectangular plates 15 that are away from each other are respectively fixedly connected to the ends of the two groups of force springs 14 that are close to each other. The upper surface of the limit block 11 is fixedly connected to two groups of support plates 9, and the bottom surface of each group of support plates 9 is in contact with the upper surface of the hexagonal ring 4. By providing the support plates 9, the support plates 9 can provide supporting force for the device, thereby achieving a better auxiliary effect.

[0024] Two limiting grooves 10 are provided on the outer surface of the circular column 1, and each group of support plates 9 has two members. The upper surfaces of the two groups of support plates 9 are commonly fixedly connected with an annular plate 8, and the upper surface of the annular plate 8 is fixedly connected with a rubber pad 2. By providing the annular plate 8 and the rubber pad 2, the rubber pad 2 can be used to closely contact the bottom of the part to be fastened, so that the part to be fastened can be fastened using the nut 3, the circular column 1 and the threaded column 7.

[0025] The interior of each limit groove 10 is snap-fitted with the outer surface of the limit column 13, and the ends of the two limit columns 13 that are away from each other are fixedly connected with handles 17. The sides of the two handles 17 that are close to each other are respectively fixedly connected to the sides of the two connecting plates 16 that are away from each other. By providing the handles 17, the limit columns 13 can be moved by pulling them by the handles 17, thereby making it convenient to apply pulling force to the limit columns 13.

[0026] The working principle of the utility model is as follows: when in use, the circular column 1 and the threaded column 7 can first be passed through the position where the thread needs to be fixed, and then the nut 3 is threaded downward from the bottom of the threaded column 7 until the rubber pad 2 contacts the bottom of the connecting component. If the limit column 13 does not correspond to the limit groove 10 at this time, it is necessary to slightly rotate the nut 3 in the opposite direction to make the rubber pad 2 separate from the bottom of the component to be fastened, and then the characteristic of the limit block 11 sliding inside the limit groove 10 can be used to drive the connecting plate 16 fixed on the upper surface of the limit block 11 to rotate, thereby adjusting the direction of the sliding connection limit column 13 inside the connecting plate 16 In the direction, please note that the limit column 13 needs to be staggered with the limit groove 10 at this time, so it is also necessary to rotate the nut 3 to make the rubber pad 2 indirectly connected to the upper surface of the nut 3 contact with the bottom of the part to be fastened. When the rubber pad 2 contacts the bottom of the part to be fastened, the thrust generated by the force spring 14 will push the limit column 13 to move to the inside of the limit groove 10, thereby ensuring that the connecting plate 16 will not rotate, thereby ensuring that the limit block 11 and the hexagonal ring 4 connected to the connecting plate 16 will not rotate. Therefore, when the device is in use, it can effectively avoid the problem of loosening of the bolts and nuts 3 due to the vibration of the wind power generation device.
