Description

Technical Field

[0001] This utility model relates to the field of modeling device technology, specifically a dynamic wake modeling device for offshore wind farms. Background Technology

[0002] Modeling apparatus is a collection of tools that transform the characteristics and laws of complex systems into observable, testable, and analyzable physical or digital models. Its core function is to help study, verify, and optimize system performance by simulating real-world scenarios.

[0003] Currently, most offshore wind farm dynamic wake modeling devices have fixed turbine positions, resulting in a fixed distance between each turbine. This prevents the turbines from being adjusted according to testing needs. Furthermore, when testing multiple turbines, most devices require them to be aligned, making it inconvenient to test turbines in staggered configurations, which is impractical for daily use. To address these issues, the inventors propose an offshore wind farm dynamic wake modeling device. Utility Model Content

[0004] To address the problems of fixed distances between wind turbines and the inconvenience of testing misaligned wind turbines, the purpose of this invention is to provide a dynamic wake modeling device for offshore wind farms.

[0020] Example: Figure 1-6 As shown, this utility model provides a dynamic wake modeling device for offshore wind farms, including a base plate 1. A fixed plate 11 is fixedly installed in the middle of the upper surface of the base plate 1. Movable plates 2 are slidably installed on both sides of the upper surface of the base plate 1 for installing mounting plates 3 and driving the mounting plates 3 on both sides to move and adjust the distance between the mounting plates 3. Mounting plates 3 are slidably installed on the upper surfaces of the fixed plate 11 and the two movable plates 2 for installing wind turbines 33 and driving the wind turbines 33 to move and adjust the distance between the wind turbines 33. Fixed seats 31 are fixedly installed in the middle of the upper surfaces of the three mounting plates 3. Movable seats 32 are slidably installed on both sides of the upper surfaces of the three mounting plates 3. Wind turbines 33 are fixedly installed on the upper surfaces of the fixed seats 31 and the movable seats 32.

[0021] Both sides of the base plate 1 are rotatably mounted with bidirectional screws 12, and both ends of the bidirectional screws 12 are threadedly connected to movable plates 2, which are used to drive the movable plates 2 to move. In use, the rotation of the bidirectional screws 12 drives the movable plates 2 to move, so that the two movable plates 2 move closer to each other or further apart.

[0022] By adopting the above technical solution, the bidirectional screw 12 can drive the moving plate 2 to move.

[0023] A crossbar 13 is rotatably mounted on one side of the base plate 1. A first bevel gear 14 is fixedly mounted on both ends of the crossbar 13. A second bevel gear 15 is fixedly mounted on one end of each of the two bidirectional screws 12 near the crossbar 13. The second bevel gear 15 meshes with the first bevel gear 14 to drive the bidirectional screws 12 to rotate. In use, the rotation of the crossbar 13 drives the first bevel gear 14 to rotate, the rotation of the first bevel gear 14 drives the second bevel gear 15 to rotate, and the rotation of the second bevel gear 15 drives the bidirectional screws 12 to rotate.

[0024] By adopting the above technical solution, the crossbar 13 can drive the bidirectional screw 12 to rotate.

[0025] A No. 1 motor 16 is fixedly installed on the side of the base plate 1, and one end of the output shaft of the No. 1 motor 16 is fixedly connected to the crossbar 13 to drive the crossbar 13 to rotate. When in use, the No. 1 motor 16 is turned on to drive the crossbar 13 to rotate.

[0026] By adopting the above technical solution, the No. 1 motor 16 can drive the crossbar 13 to rotate.

[0027] Both the fixed plate 11 and the two movable plates 2 are rotatably mounted with drive screws 21, and the drive screws 21 are threadedly connected to mounting plates 3, which are used to drive the mounting plates 3 to move. In use, the drive screws 21 are rotated to drive the mounting plates 3 to move.

[0028] By adopting the above technical solution, the drive screw 21 can drive the mounting plate 3 to move.

[0029] Each of the three mounting plates 3 has a double-ended screw 34 rotatably mounted inside, and both ends of the double-ended screw 34 are threadedly connected to a movable seat 32. Mounting brackets 22 are fixedly mounted on one side of the upper surface of the fixed plate 11 and the two movable plates 2. A transmission rod 25 is rotatably mounted inside the side of the three mounting brackets 22 near the mounting plate 3, and the end of the transmission rod 25 away from the mounting bracket 22 is slidably inserted into the double-ended screw 34 to drive the movable seat 32 to move. In use, the rotation of the transmission rod 25 drives the double-ended screw 34 to rotate, and the rotation of the double-ended screw 34 drives the movable seat 32 to move, so that the two movable seats 32 move closer to each other or further apart.

[0030] By adopting the above technical solution, the transmission rod 25 can drive the movable seat 32 to move.

[0031] Each of the three mounting brackets 22 has a sleeve 23 rotatably mounted on the side away from the transmission rod 25. A third bevel gear 24 is fixedly mounted on the end of the sleeve 23 near the transmission rod 25, and a fourth bevel gear 26 is fixedly mounted on the end of the transmission rod 25 near the mounting bracket 22. The fourth bevel gear 26 meshes with the third bevel gear 24 to drive the transmission rod 25 to rotate. The rotation of the sleeve 23 drives the third bevel gear 24 to rotate, the rotation of the third bevel gear 24 drives the fourth bevel gear 26 to rotate, and the rotation of the fourth bevel gear 26 drives the transmission rod 25 to rotate.

[0032] By adopting the above technical solution, the sleeve 23 can drive the transmission rod 25 to rotate.

[0033] Two support plates 17 are fixedly installed on the side of the base plate 1 near the mounting bracket 22. A drive rod 18 is rotatably installed inside the two support plates 17, and one end of the drive rod 18 rotatably passes through the mounting bracket 22, the sleeve 23 and the third bevel gear 24. The sleeve 23 is slidably sleeved on the drive rod 18. A second motor 19 is fixedly installed on the side of the right support plate 17, and one end of the output shaft of the second motor 19 is fixedly connected to the drive rod 18 to drive the sleeve 23 to rotate. In use, the second motor 19 is turned on to drive the drive rod 18 to rotate. The rotation of the drive rod 18 drives the sleeve 23 to rotate through a key / spline structure.

[0034] By adopting the above technical solution, the No. 2 motor 19 can drive the sleeve 23 to rotate.

[0035] Working principle: First, when adjusting the distance between each row of fans 33, the first motor 16 is turned on to drive the crossbar 13 to rotate. The rotation of the crossbar 13 drives the first bevel gear 14 to rotate, which in turn drives the second bevel gear 15 to rotate. The rotation of the second bevel gear 15 drives the double screw 12 to rotate, which in turn drives the moving plate 2 to move. The distance between the two moving plates 2 and the fixed plate 11 is adjusted, thereby adjusting the distance between each row of fans 33. Secondly, when adjusting the distance between the exhaust fans 33, the second motor 19 is turned on to drive the drive rod 18 to rotate. The rotation of the drive rod 18 drives the sleeve 23 to rotate. The rotation of the sleeve 23 drives the third bevel gear 24 to rotate. The rotation of the third bevel gear 24 drives the fourth bevel gear 26 to rotate. The rotation of the fourth bevel gear 26 drives the transmission rod 25 to rotate. Then, the rotation of the transmission rod 25 drives the double-headed screw 34 to rotate, and the rotation of the double-headed screw 34 drives the moving seat 32 to move, adjusting the distance between the two moving seats 32 and the fixed seat 31, thereby adjusting the distance between the exhaust fans 33. Finally, to achieve the desired staggered arrangement of the fans 33, the drive screw 21 is rotated to move the mounting plate 3. The position of each row of fans 33 is adjusted by the movement of the mounting plate 3, thereby achieving the staggered arrangement of the fans 33.
