Description
Technical Field
[0001] This utility model relates to the field of fastener technology for wind power generation equipment, specifically a high-stability nut for wind power generation equipment. Background Technology
[0002] A nut is a cylindrical or hexagonal fastener with an internally threaded hole, typically used in conjunction with bolts or screws. It connects and secures two or more components together through the meshing of the threads. High-stability nuts for wind power generation equipment are special fasteners designed for critical connection parts of wind turbine generators. They are capable of maintaining connection tightness and preventing loosening and failure under extreme environments and dynamic loads for extended periods. They are not simply an upgrade of ordinary industrial nuts, but rather a systematic optimization of materials, structure, and surface treatment to meet the stringent requirements of wind power scenarios. They are one of the core basic components ensuring the safe, efficient, and long-term operation of wind turbines.
[0003] The high-stability nuts used in existing wind power equipment are inconvenient to prevent loosening during application, which eventually leads to loosening of the nuts and affects the connection stability of the wind power equipment.
[0004] Therefore, a high-stability nut for wind power generation equipment is needed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a high-stability nut for wind power generation equipment to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-stability nut for wind power generation equipment, comprising a nut, wherein a screw is provided inside the nut; The anti-detachment unit includes an anti-detachment component and a pressing component. The anti-detachment component is used to prevent the nut and screw from detaching, and the pressing component is used to press the anti-detachment component to ensure the anti-detachment effect of the nut. The adaptation unit is used to adapt to screws with different pitches, so as to assist the anti-loosening unit in preventing the nut from being dislodged. With the cooperation of the anti-loosening unit and the adaptation unit, the nut and screw can be prevented from being dislodged to ensure the connection stability of the wind power generation equipment. Under the limitation of the adaptation unit, it can adapt to screws with different pitches.
[0007] Preferably, the anti-detachment component includes a fixing block, a connecting shaft is connected to the side wall of the fixing block, and a rotating sleeve is rotatably connected to the outer wall of the connecting shaft.
[0008] Preferably, the pressing assembly includes a slide rod, a retaining ring connected to the end of the slide rod, a pressure ring sleeved on the outer wall of the slide rod, a rubber ring connected to the inner wall of the pressure ring, and a spring provided on the top surface of the pressure ring.
[0009] Preferably, the rubber ring is made of rubber, and the inner side of the rubber ring is slidably disposed with respect to the outer wall of the rotating sleeve. Under the constraint of the rubber ring made of rubber, the coefficient of friction between the rubber ring and the outer wall of the rotating sleeve can be increased, so that the rubber ring can stably press the rotating sleeve.
[0010] Preferably, the end of the slide rod away from the retaining ring is connected to the top surface of the nut, and there are four slide rods distributed around the center of the nut. With the support of the slide rods, the pressure ring slides stably.
[0011] Preferably, the adaptation unit includes a slide groove, a first magnetic block is connected to the inner wall of the slide groove, a second magnetic ring is slidably connected inside the slide groove, and a retaining plate is connected to the side wall of the second magnetic ring.
[0012] Preferably, the second magnetic ring and the first magnetic block are magnetically repulsive, and the outer wall of the card plate is slidably connected to the inside of the groove. Under the restriction of magnetic repulsion, a thrust can be applied to the rotating sleeve to prevent the nut from loosening. At the same time, the card plate can be adjusted according to the pitch.
[0013] Preferably, the groove is formed inside the rotating sleeve, and the retaining plate is slidably connected to the rotating sleeve. Under the magnetic repulsion restriction of the retaining plate, the rotating sleeve can be pushed downward to prevent the nut from loosening.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This wind power generation equipment uses a high-stability nut, with an anti-loosening unit as one component. When the wind power generation equipment is connected via the nut, to prevent the nut from loosening, the rotating sleeve is rotated around the connecting shaft, causing the clamping plate of the adaptation unit to precisely engage with the screw thread pitch. Subsequently, the pressure ring is released, and under the action of the spring force, the retaining ring at the end of the slide rod pushes the pressure ring down along the slide rod, causing the rubber ring on the inner side of the pressure ring to tightly press against the outer wall of the rotating sleeve, restricting the rotation of the rotating sleeve. Through the double locking structure of the clamping plate and the screw thread engagement, and the rubber ring pressing against the rotating sleeve, the nut can be effectively prevented from loosening, ensuring the long-term stability of the nut connection to the wind power generation equipment and resisting the risk of loosening caused by vibration during equipment operation. 2. This wind power generation equipment uses a high-stability nut, which is composed of an adaptive unit. When the nut is fitted onto the screw, rotating the sleeve causes the clamping plate to engage with the screw thread pitch. Because the clamping plate and the sleeve are internally slidably connected, the engagement state of the clamping plate and the thread pitch can be adaptively adjusted according to the actual position of the nut on the screw, adapting to the fastening requirements of different installation positions. Simultaneously, under the magnetic repulsion between the second magnetic ring and the first magnetic block, a continuous downward thrust is applied to the sleeve, further preventing the nut from loosening. This unit works in conjunction with the anti-loosening unit, achieving both adaptive adjustment of the clamping plate and enhanced anti-loosening effect through magnetic force, improving the connection reliability of the nut under complex operating conditions.

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0023] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides a high-stability nut for wind power generation equipment, including a nut 1, and a screw is provided inside the nut 1; Anti-detachment unit 2 includes an anti-detachment component and a pressing component. The anti-detachment component is used to prevent the nut 1 from detaching from the screw, and the pressing component is used to press the anti-detachment component to ensure the anti-detachment effect of the nut 1. The adaptation unit 3 is used to adapt to screws with different pitches, so as to assist the anti-loosening treatment of nut 1 through anti-loosening unit 2.
[0024] When in use, with the cooperation of the anti-detachment unit 2 and the adaptation unit 3, the nut 1 and the screw can be prevented from detaching to ensure the connection stability of the wind power generation equipment. Under the restriction of the adaptation unit 3, it can adapt to screws with different pitches.
[0025] Example 2 Reference Figure 3 and Figure 4This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiment, as detailed below: The anti-detachment component includes a fixing block 21, a connecting shaft 22 connected to the side wall of the fixing block 21, and a rotating sleeve 23 rotatably connected to the outer wall of the connecting shaft 22. The pressing component includes a slide rod 27, a retaining ring 28 connected to the end of the slide rod 27, a pressure ring 24 sleeved on the outer wall of the slide rod 27, a rubber ring 25 connected to the inner wall of the pressure ring 24, and a spring 26 provided on the top surface of the pressure ring 24.
[0026] Among them, the rubber ring 25 is made of rubber, and the inner side of the rubber ring 25 is slidably arranged with the outer wall of the rotating sleeve 23. Under the restriction of the rubber ring 25, the friction coefficient between it and the outer wall of the rotating sleeve 23 can be increased, so that the rubber ring 25 can stably press the rotating sleeve 23.
[0027] Among them, the end of the slide rod 27 away from the retaining ring 28 is connected to the top surface of the nut 1. There are four slide rods 27, which are distributed around the center of the nut 1. With the support of the slide rods 27, the pressure ring 24 slides stably.
[0028] When the wind power generation equipment is connected via nut 1, to prevent nut 1 from loosening during use, rotate the rotating sleeve 23. Rotate the sleeve around the point of rotational connection with the connecting shaft 22 as the rotation center. This engages the clamping plate 34 in the adaptation unit 3 with the screw thread pitch. At this time, release the pressure ring 24. Under the elastic action of the spring 26, the retaining ring 28 fixedly installed at the end of the slide rod 27 pushes the pressure ring 24 downward. The pressure ring 24 slides on the outer wall of the slide rod 27, causing the inner side of the rubber ring 25 to slide and press against the outer wall of the rotating sleeve 23, preventing the rotating sleeve 23 from rotating. With the rotating sleeve 23 and clamping plate 34 engaging with the screw thread pitch and the pressure restriction of the rubber ring 25, the nut 1 can be prevented from loosening, ensuring that the nut 1 can be stably connected to the wind power generation equipment.
[0029] Example 3 Reference Figure 5 and Figure 6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment is further optimized based on the above embodiments, as detailed below: The adaptation unit 3 includes a slide 31, a first magnetic block 32 connected to the inner wall of the slide 31, a second magnetic ring 33 slidably connected inside the slide 31, and a card plate 34 connected to the side wall of the second magnetic ring 33.
[0030] The second magnetic ring 33 and the first magnetic block 32 are magnetically repulsive. The outer wall of the clamping plate 34 is slidably connected to the inside of the slide groove 31. Under the restriction of magnetic repulsion, a thrust can be applied to the rotating sleeve 23 to prevent the nut 1 from loosening. At the same time, the clamping position of the clamping plate 34 can be adjusted according to the pitch.
[0031] The slide groove 31 is opened inside the rotating sleeve 23, and the clamping plate 34 is slidably connected to the rotating sleeve 23. Under the magnetic repulsion restriction of the clamping plate 34, the rotating sleeve 23 can be pushed downward to prevent the nut 1 from loosening.
[0032] In use, when the nut 1 is fitted onto the screw, rotating the sleeve 23 causes the clamping plate 34 to engage with the screw pitch. Under the magnetic repulsion constraint of the second magnetic ring 33 and the first magnetic block 32, a downward force can be applied to the sleeve 23 to prevent the nut 1 from loosening from the screw. With the help of the anti-loosening unit 2, the nut 1 can be prevented from loosening. Since the outer wall of the clamping plate 34 is slidably connected to the inside of the sleeve 23, under its constraint, it can be adaptively engaged with the screw pitch according to the position of the nut 1 on the screw. This structure can adaptively adjust the length of the clamping plate 34 according to the pitch, and under the magnetic repulsion constraint, a downward pushing force can be applied to the sleeve 23 to achieve the anti-loosening treatment of the nut 1.
[0033] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
