Description

Technical Field

[0001] This utility model relates to the technical field of wind power installation platforms, specifically to an offshore wind power installation platform. Background Technology

[0002] Offshore wind power refers to wind power generation equipment installed in the sea. Offshore wind power installation requires a special platform, namely a wind turbine installation vessel, to which the wind turbine components are fixed and then transported to a designated location. The components are then lifted and installed using the cranes on the installation vessel. The above describes the operation steps of the installation platform.

[0003] Currently, the installation platform has connection points corresponding to the wind turbine towers. The towers are fixed to the connection points with screws. The size of the connection points is the same as the size and configuration requirements of the actual installation of the towers. However, the towers are tall and come into contact with the wind when sailing at sea, which can easily affect the stability of the towers. Therefore, an offshore wind power installation platform is proposed here. Utility Model Content

[0004] The technical problem this utility model aims to solve is that current installation platforms have connection points corresponding to wind turbine towers, and the towers are fixed to these connection points with screws. The size of the connection points is the same as the actual size and configuration requirements of the towers for installation. However, the towers are relatively tall and come into contact with the wind during sea navigation, which can easily affect their stability. This invention provides an offshore wind power installation platform that can add auxiliary diagonal bracing devices to the traditional connection, providing additional diagonal support for the towers, ensuring the stability of the tower placement, and reducing the impact of wind on the towers during transportation.

[0005] The technical solution adopted by this utility model to solve the technical problem is: an offshore wind power installation platform, including a connecting platform, with fixed sleeve columns fixedly connected at equal intervals on the top side wall of the connecting platform, and connecting sleeve columns telescopically installed inside the fixed sleeve columns. The connecting sleeve columns have an inner groove, and a docking ring is fixedly connected to the inner wall of the inner groove. Four side uprights are provided on the outer side wall of the fixed sleeve columns, and an arc-shaped extension plate is fixedly connected to the top of the side uprights. A top support plate is rotatably connected to one end edge of the arc-shaped extension plate. The side uprights on each fixed sleeve column are staggered.

[0006] As a preferred technical solution of this utility model, a bottom groove is provided inside the fixed sleeve column, and four movable grooves are provided equidistantly through the outer ring wall of the fixed sleeve column. A motor is detachably connected to one side wall of the movable groove, and a linkage column is detachably connected to the output end of the motor.

[0007] As a preferred technical solution of this utility model, one end of the linkage column is fixedly connected to the bottom side wall of the side plate, and the linkage column and the side plate are in an L-shaped structure. The end of the linkage column away from the side plate extends into the bottom groove and is located at the bottom of the connecting sleeve column.

[0008] As a preferred technical solution of this utility model, a groove is provided in the middle of the side wall of the top support plate away from the arc-shaped extension plate. An electromagnet is detachably embedded in the groove. A rubber pad is fixedly connected to one side wall of the electromagnet. The rubber pad is in contact with the outer wall of the tower column.

[0009] As a preferred technical solution of this utility model, the top sidewall of the bottom groove is uniformly fixedly connected with limiting columns, the limiting columns are inserted into the sidewall of the bottom of the connecting sleeve column and near the edge, and the inner groove is inserted with a tower column, and the tower column is detachably connected to the docking ring using screws and bolts.

[0010] This utility model has the following advantages: The bottom end of the tower column is inserted into the inner groove. As the tower column settles, it will press down the connecting sleeve column. The connecting sleeve column presses down the linkage column, thereby driving the linkage column to rotate along the output shaft of the motor. This drives the side upright plate and the arc-shaped extension plate to rotate and move closer to the tower column. Finally, it drives the top support plate to fit against the tower column, thereby realizing the function of four-sided diagonal support for the tower column, improving the stability of the tower column placement. In conjunction with the connection between the tower column and the docking ring, it effectively reduces the impact of wind on the tower column during transportation. Because the tower column is less affected by wind, it can also reduce the impact on the installation vessel, ensuring the stability of the installation vessel's navigation.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to the following: Figure 1-3 This utility model discloses an offshore wind power installation platform, including a connecting platform 1. Fixed sleeve columns 2 are fixedly connected at equal intervals to the top side wall of the connecting platform 1. Connecting sleeve columns 3 are telescopically movably provided inside the fixed sleeve columns 2. The connecting sleeve columns 3 have an inner groove 4 inside. A docking ring 5 is fixedly connected to the inner wall of the inner groove 4. Four side upright plates 6 are provided on the outer side wall of the fixed sleeve columns 2. An arc-shaped extension plate 7 is fixedly connected to the top of the side upright plate 6. A top support plate 8 is rotatably connected to one end edge of the arc-shaped extension plate 7. The side upright plates 6 on each fixed sleeve column 2 are staggered.

[0017] The technical effect of this solution is as follows: the tower column is hoisted above the connecting sleeve column 3 by a crane and inserted into the inner groove 4. The connection between the tower column and the docking ring 5 is locked with screws and nuts. As the tower column is pressed down, the connecting sleeve column 3 will be driven to descend. As the connecting sleeve column 3 descends, it will press down the linkage column 10, thereby driving the linkage column 10 to rotate. As the linkage column 10 rotates, it will drive the side upright plate 6 and the arc-shaped extension plate 7 to move, thereby driving the top support plate 8 to approach the tower column. Finally, the top support plate 8 is tightly attached to the outer wall of the tower column. The four side upright plates 6, the arc-shaped extension plate 7 and the top support plate 8 can achieve four-point support, effectively increasing the diagonal bracing force and improving the wind resistance of the tower column.

[0018] The fixed sleeve 2 has a bottom groove 12. The outer ring wall of the fixed sleeve 2 has four movable grooves 9 that are equidistantly connected. A motor 11 is detachably connected to one side wall of the movable groove 9. The output end of the motor 11 is detachably connected to a linkage column 10. One end of the linkage column 10 is fixedly connected to the bottom side wall of the side plate 6. The linkage column 10 and the side plate 6 are in an L-shaped structure. The end of the linkage column 10 away from the side plate 6 extends into the bottom groove 12 and is located at the bottom of the connecting sleeve 3.

[0019] The technical effects of this solution are as follows: To ensure effectiveness, the motor 11 is designed to rotate freely even without power. This ensures that the connecting sleeve column 3 can effectively drive the linkage column 10. When needed, the motor 11 can be powered on to apply a rotational torque to the linkage column 10, thereby applying a compressive force to the top support plate 8, making the top support plate 8 tightly fit against the outer wall of the tower column, thus improving the stability of the support. The reverse rotation of the motor 11 can also lift the connecting sleeve column 3 and remove the top support plate 8, ensuring the smooth installation of the tower column.

[0020] A groove 14 is provided in the middle of the side wall of the top support plate 8 away from the arc extension plate 7. An electromagnet 15 is detachably embedded in the groove 14. A rubber pad 16 is fixedly connected to one side wall of the electromagnet 15. The rubber pad 16 fits against the outer wall of the tower column. A limiting column 13 is evenly fixedly connected to the top side wall of the bottom groove 12. The limiting column 13 is inserted into the side wall of the bottom of the connecting sleeve column 3 near the edge. A tower column is inserted into the inner groove 4, and the tower column is detachably connected to the docking ring 5 using screws and bolts.

[0021] The technical effects of this solution are as follows: the limiting column 13 fixed to the bottom side wall of the bottom groove 12 can limit the connecting sleeve column 3, ensuring that the connecting sleeve column 3 can perform stable vertical lifting and lowering activities, avoiding connection failure due to the tilt of the connecting sleeve column 3 when connecting with the tower column, which would increase transportation time. It can also ensure that the connecting sleeve column 3 can simultaneously press down on the four linkage columns 10, preventing the four side upright plates 6 and the arc extension plate 7 from failing to effectively limit the oblique support of the tower column due to asynchronous operation. The electromagnet 15 connected in the top support plate 8 can increase the stability of the top support plate 8 and the tower column by magnetic attraction. The rubber pad 16 can also prevent wear on the tower column.

[0022] Specifically, when using this utility model, a crane on the installation vessel is used to lift the tower column and place it above the corresponding fixed sleeve column 2, ensuring that the bottom end of the tower column is aligned with the connecting sleeve column 3. Then, the tower column is gradually lowered. When the bottom of the tower column is in contact with the docking ring 5, the workers use screws and nuts to lock and reinforce it. Then, the crane continues to lower the tower column. As the tower column loses the suspension of the crane, its weight will press down on the connecting sleeve column 3. The connecting sleeve column 3 will descend under this force, pressing down on one end of the linkage column 10. Under the action of this force, the linkage column 10 will rotate along the output shaft of the motor 11, thereby driving the side plate 6 and the arc-shaped extension plate 7 to move. Finally, it drives the top support plate 8 to fit against the outer wall of the tower column, achieving the effect of limiting the diagonal bracing of the tower column. When necessary, the motor 11 is started to apply a force to the top support plate 8 to ensure that the top support plate 8 fits tightly against the tower column. At the same time, the electromagnet 15 inside the top support plate 8 can ensure the tightness of the fit between the top support plate 8 and the tower column.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
