Description

Technical Field

[0001] The utility model belongs to the technical field of wind power generation towers, and particularly relates to a wind power generation tower damping structure. Background Art

[0002] The wind turbine tower is the core component of the wind power generation system. Its main function is to use wind power to drive the windmill blades to rotate, and then increase the rotation speed through the speed increaser to drive the generator to generate electricity.

[0003] At present, a Chinese utility model with announcement number CN218780704U discloses a wind power tower damping structure, including a first disc-shaped seat, a support column is vertically installed on the top of the first disc-shaped seat, and a plurality of positioning columns are vertically installed at equal intervals on the top of the first disc-shaped seat and around the support column. A number of annular counterweights are sleeved on each positioning column, and the annular counterweights are stacked together. When the wind power tower swings, the annular counterweights will quickly make a movement opposite to the swinging direction, and at this time interact with the hydraulic damper to quickly stabilize and return the counterweights.

[0004] However, the existing wind power tower damping structure cannot effectively facilitate users to rotate and adjust according to wind direction, and cannot effectively reduce the swing amplitude of the wind power tower. To solve the above problems, we provide a wind power tower damping structure. Utility Model Content

[0005] The utility model aims to provide a wind power generation tower damping structure to solve the problems raised by the above-mentioned background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a wind power tower damping structure, comprising an outer ring, an inner ring is arranged inside the outer ring, a gear ring is bolted to the outer side of the inner ring, a gear is rotatably connected to the outer side of the outer ring through a bearing, the surface of the gear is meshed with the gear ring through teeth, a motor is bolted to the top of the outer ring, the output end of the motor is bolted to the gear through a coupling, balls are arranged on the top and bottom of the inner ring, an arc groove 1 adapted to the ball is provided on the top and bottom of the inner ring, an arc groove 2 adapted to the ball is provided inside the outer ring, two sliding rods are bolted to the inner side of the inner ring, a sliding sleeve is slidably connected to the surface of the sliding rod, a slider is bolted to the surface of the sliding sleeve, springs are bolted to both sides of the slider, and the other end of the spring is bolted to the inner ring.

[0007] The above technical solution is adopted: the user installs the device inside the wind power tower through the mounting plate and the mounting bolts, and then starts the motor to drive the gear to rotate, so that the gear drives the inner ring to rotate through the gear ring, and at the same time the inner ring rotates inside the outer ring through the ball, so that the user can effectively adjust the rotation according to the wind direction. When the wind power tower swings against the wind, the slider drives the sliding sleeve to slide on the surface of the sliding rod, and the slider slides in the opposite direction of the wind power tower. At the same time, the spring pulls the slider, so that the swing amplitude of the wind power tower can be effectively reduced.

[0008] The utility model is further configured that a mounting rod is arranged on the outer side of the outer ring, and one end of the mounting rod is bolted to the outer ring.

[0009] By adopting the above technical solution, the outer ring can be effectively connected by arranging the mounting rod.

[0010] The utility model is further configured that one end of the mounting rod is bolted to a mounting plate, and the interior of the mounting plate is sleeved with mounting bolts.

[0011] By adopting the above technical solution, the device can be effectively and conveniently installed by providing a mounting plate and mounting bolts.

[0012] The utility model is further configured that the top of the sliding block is bolted with two vertical rods, and the surfaces of the vertical rods are sleeved with counterweight blocks.

[0013] By adopting the above technical solution, the counterweight of the device can be effectively and conveniently adjusted by setting a counterweight block.

[0014] The utility model is further configured that a round hole matching the vertical rod is opened inside the counterweight block.

[0015] By adopting the above technical solution, the counterweight block can be effectively installed by arranging the vertical rod.

[0016] In summary, the utility model has the following beneficial effects:

[0017] 1. The user installs the device inside the wind power tower through the mounting plate and mounting bolts, and then starts the motor to drive the gear to rotate, so that the gear drives the inner ring to rotate through the gear ring, and the inner ring rotates inside the outer ring through the ball, so that the user can effectively adjust the rotation according to the wind direction;

[0018] 2. When the wind power tower swings against the wind, the slider drives the sliding sleeve to slide on the surface of the sliding rod. The slider slides in the opposite direction of the wind power tower. At the same time, the spring pulls the slider, thereby effectively reducing the swing amplitude of the wind power tower.
