Description

Technical Field

[0001] This utility model belongs to the field of wind turbine technology, and in particular relates to a wind turbine support that is easy to adjust. Background Technology

[0002] A related technology, CN109026548A, discloses an adjustable wind turbine blade support. This device allows for height adjustment of the wind turbine by screwing together a support pipe and a threaded rod. A ladder facilitates maintenance, wire holes facilitate turbine fixation, and an arc-shaped support frame ensures blade stability. A first bearing between the arc-shaped support frame and the threaded rod allows for rotation, and a triangular bracket secures the solar panel. This invention is rationally designed, simple in structure, and facilitates adjustment of the bolt height and blade rotation direction, making it worthy of widespread promotion.

[0003] However, when using this device, it is not easy to prevent the threaded rod from reversing due to the weight of the wind turbine and the vibration of the device during operation, which causes the height of the wind turbine to deviate from the preset value, making it difficult to maintain the appropriate wind speed height for a long time, thus reducing the power generation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an easily adjustable wind turbine support. By setting a self-locking part, it solves the problem that when the device is in use, it is not easy to prevent the threaded rod from reversing due to the weight of the wind turbine and the vibration of the device during operation, which would cause the height of the wind turbine to deviate from the preset value, making it difficult to maintain the appropriate wind speed height for a long time, thereby reducing the power generation efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an easily adjustable wind turbine support, comprising a base plate and a cylindrical support fixedly connected to the top of the base plate, with an mounting plate disposed above the cylindrical support. It also includes a self-locking part disposed on the cylindrical support and a height adjustment part mounted on the cylindrical support. The self-locking part is used to lock the height adjustment part after height adjustment, the cylindrical support is fixedly connected to the top of the height adjustment part, and the height adjustment part is used to adjust the height of the mounting plate.

[0007] Furthermore, the self-locking part includes a limiting component disposed on the outer wall of the cylindrical support; and an elastic component disposed on the cylindrical support; wherein the elastic component and the limiting component cooperate with each other to prevent the height adjustment part from becoming loose.

[0008] Furthermore, the height adjustment unit includes a transmission assembly disposed on a cylindrical support; and a guide assembly mounted on the cylindrical support; wherein the guide assembly provides guidance for the movement of the mounting plate.

[0009] Furthermore, the limiting component includes a rotating shaft rotatably connected to the outer wall of the cylindrical support. A protective shell is rotatably connected to the outer wall of the rotating shaft, and a plurality of limiting grooves are formed on the inner wall of the protective shell. The left side of the rotating shaft extends into the cylindrical support, and the left side of the protective shell is fixedly connected to the cylindrical support. During height adjustment, the limiting component restricts the rotation angle and position of the rotating shaft. The elastic buckle engages with the limiting groove to lock the height adjustment part, preventing it from rotating due to external force and ensuring that the height of the wind turbine support is fixed.

[0010] Furthermore, the elastic component includes a ring slidably connected to the outer wall of the protective shell. Several elastic buckles are fixedly connected to the outer wall of the ring. A spring is provided on the right side of the ring, and a sliding element is provided on the protective shell. The elastic buckles extend from the side away from the rotating shaft into corresponding limiting grooves. The spring is sleeved on the rotating shaft, and its right side is fixedly connected to the protective shell. The spring abuts against the ring and is in a compressed state, continuously pressing against the ring. The sliding element includes a handle located on the right side of the ring. A sliding groove is formed on the outer wall of the protective shell, and the handle is slidably connected to the sliding groove. An annular sliding groove is formed on the right side of the ring, and the left side of the handle slides into the annular sliding groove. The elastic component utilizes the elastic force of the spring to push the ring and elastic buckles, ensuring they remain engaged with the limiting groove, thus enhancing the reliability of the self-locking mechanism.

[0011] Furthermore, the transmission assembly includes a threaded rod rotatably connected to the top of the base plate, a bevel gear one sleeved on the outer wall of the rotating shaft, a bevel gear two fixedly connected to the outer wall of the threaded rod, and an extension bracket inside the cylindrical bracket; wherein, the bevel gear one and the bevel gear two mesh, the top of the threaded rod extends into the extension bracket, the threaded rod is threadedly connected to the extension bracket, the mounting plate is fixedly connected to the top of the extension bracket, and the transmission assembly transmits the rotation of the rotating shaft to the threaded rod through the meshing of the bevel gear one and the bevel gear two. By utilizing the threaded connection between the threaded rod and the extension bracket, the rotational motion is converted into linear motion, realizing the height adjustment of the mounting plate and the wind turbine, providing a feasible power transmission path and adjustment method for the height adjustment of the bracket.

[0012] Furthermore, the guiding assembly includes several limiting sliders fixedly connected to the outer wall of the extension bracket, and several limiting sliders are provided on the inner wall of the cylindrical bracket; wherein, the several limiting sliders are slidably connected to the inner walls of several limiting grooves respectively. Through the slidable connection between the limiting sliders on the outer wall of the extension bracket and the limiting grooves on the inner wall of the cylindrical bracket, the lifting and lowering movement of the extension bracket is guided and limited, ensuring that the extension bracket remains stable during the lifting and lowering process, avoiding swaying or deviation, and enabling the mounting plate and wind turbine to move smoothly along the predetermined direction, ensuring the accuracy and stability of height adjustment.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting a self-locking part, when the shaft rotates, the ring on it also rotates. The shaft drives several elastic buckles on it to rotate around the shaft. Analyzing one of the elastic buckles, the others are similar. When the elastic buckle rotates around the shaft, it will be squeezed by the limiting groove, causing it to deform until the elastic buckle slides into the next limiting groove. The elastic buckle then springs back and locks into the limiting groove, completing the self-locking. To engage the self-locking, simply pull the handle to the right. The handle, through the ring, drives several elastic buckles to separate from the corresponding limiting grooves, thus allowing the shaft to reverse. After adjustment, release the handle. The spring returns and drives several elastic buckles to lock into the corresponding limiting grooves, completing the self-locking again. This keeps the height adjustment part in a fixed state after adjustment, preventing the threaded rod from reversing due to the weight of the wind turbine and vibration during operation. This ensures that the wind turbine is always at a suitable height, thereby improving power generation efficiency.

[0015] 2. By setting up a height adjustment unit, when adjusting the height of the device, rotating the shaft drives bevel gear one to rotate bevel gear two, which in turn drives the threaded rod to rotate. The threaded rod drives the extension bracket connected to it to rise. The extension bracket rises under the limit of several limit sliders and several limit grooves, and the mounting plate also rises accordingly, thereby driving the wind turbine mounted on the mounting plate to rise. Conversely, after contacting the self-locking mechanism, reversing the shaft lowers the height of the wind turbine, thus completing the height adjustment of the bracket. The wind turbine can be adjusted to a suitable height according to the wind speed at different heights, ensuring that the equipment is always at the optimal wind speed height, thereby maintaining the generator's efficient power generation state.
