Description

Technical Field

[0001] This utility model relates to the field of wind power installation vessel technology, and in particular to a tower limiting device for offshore wind power installation vessels. Background Technology

[0002] In offshore wind power projects, the wind turbine tower is the support structure for wind power generation. It plays a crucial role in supporting the wind turbine generator set and absorbing vibrations from the generator. The transportation of the wind turbine tower is a critical part of the entire project. When using installation vessels to transport the tower over long distances at sea, it is necessary to use fixing devices to secure it. However, with existing rope fixing methods, the connection effectiveness and strength of the ropes will decrease to some extent when the ship is in rough seas and under prolonged swaying, which is not conducive to long-term fixation.

[0003] An invention patent, titled "A Fixing Device and Fixing Method for Offshore Wind Turbine Installation Ship Towers," with application number CN202510293979.4, describes a device comprising: a tower, with an inner abutment mechanism equidistantly sleeved on the outer side of the tower. The inner abutment mechanism includes inner abutment plates arranged in a circumferential array on the outer wall of the tower. A monitoring mechanism is located at the bottom of the inner abutment plates at the top. The monitoring mechanism includes an inner groove, a feedback plate, a primary equipment slot, a photoelectric transmitter, a secondary equipment slot, and a receiver. The inner groove is located in the middle of the bottom of the inner abutment plate, the feedback plate slides within the inner groove, and the primary equipment slot is located within... The inner plate is connected to the top of the inner groove opening. This fixing device can conveniently and quickly fix the tower while monitoring its fixing status in real time. When the tower moves horizontally, the information can be fed back to the external terminal so that personnel can understand it in time. The above patent only considers the fixing of the tower. When the tower is transported to the required position, it is usually removed by a crane and installed with assistance. However, the fixing structure in the above solution is around the outer circumference of the tower. The tower can only be pulled out before hoisting. The tower cannot be lifted directly, which increases the difficulty of hoisting and needs to be improved. Summary of the Invention

[0004] To address the aforementioned issues, a shipboard tower limiting device for offshore wind power installation is provided, aiming to resolve the problems existing in the prior art.

[0005] The specific technical solution is as follows:

[0006] A limiting device for a ship's offshore wind turbine tower includes a tower, a base, a load-bearing component, and multiple inner abutment components. The base is fixed to the hull by bolts. The load-bearing component is disposed on the base. The top of the load-bearing component can be opened to form a channel for the tower to be inserted. When the load-bearing component is closed, it forms a cylindrical structure surrounding the outer periphery of the tower. The multiple inner abutment components are evenly distributed on the inner sidewall of the cylindrical structure, and the abutting ends of the inner abutment components face the tower.

[0007] The aforementioned offshore wind power installation vessel tower limiting device also has the following features: the bearing assembly includes a lower bearing body, a left bearing body, and a right bearing body. The lower bearing body has a semi-circular cross-section and is mounted on the base. The left and right bearing bodies are symmetrically distributed on the left and right sides of the lower bearing body, and both the left and right bearing bodies are hinged to the lower bearing body. When the end of the left bearing body away from the lower bearing body and the end of the right bearing body away from the lower bearing body are in contact with each other, the lower bearing body, the left bearing body, and the right bearing body together form a cylindrical structure surrounding the outer periphery of the tower. The end of the left bearing body away from the lower bearing body and the end of the right bearing body away from the lower bearing body are both provided with connecting parts.

[0008] The beneficial effect is that when it is necessary to put into or take out the tower, the connecting part can be opened and the left and right supporting bodies can be rotated respectively, so that the side wall of the cylindrical structure can be opened, making it convenient to move the tower.

[0009] The aforementioned offshore wind power installation ship tower limiting device also has the following feature: the connecting part includes two connecting bodies, which are respectively disposed on the outer side of the left bearing body away from the lower bearing body and the outer side wall of the right bearing body away from the lower bearing body. Both connecting bodies are provided with through holes. When the two connecting bodies are fitted together, bolts can pass through the through holes, so that the two connecting bodies are connected to each other.

[0010] The beneficial effect is that after the tower is placed into the cylindrical structure, the left and right load-bearing bodies can be fixed with bolts to prevent the tower from falling out.

[0011] The aforementioned offshore wind power installation ship tower limiting device also has the following features: the inner abutment component includes an abutment block and a telescopic rod; the inner sidewall of the cylindrical structure has grooves that correspond one-to-one with the inner abutment component; one end of the telescopic rod is connected to the bottom wall of the groove; the abutment block is disposed at the other end of the telescopic rod; when the telescopic rod is shortened to its shortest state, the abutment block fits precisely against the inner sidewall of the cylindrical structure.

[0012] The beneficial effects are: the extension of the telescopic rod allows the abutment block to abut against the side wall of the tower, and multiple abutment blocks abut against the outer periphery of the tower, thus fixing the relative position of the tower and the load-bearing components.

[0013] The aforementioned offshore wind power installation ship tower limiting device also has the following feature: a detachable anti-slip pad is provided on the side of the abutment block away from the telescopic rod, and the surface of the anti-slip pad facing the tower is provided with anti-slip texture.

[0014] The beneficial effects are: since the cylindrical structure fixes the tower inside, the tower and the cylindrical structure can only move along the length of the tower. The anti-slip pads and anti-slip patterns prevent relative displacement between the tower and the cylindrical structure.

[0015] In summary, the beneficial effects of this scheme are:

[0016] The offshore wind turbine installation vessel tower limiting device provided by this utility model features an openable load-bearing component, allowing for easy installation and removal of the tower using a crane. This device enables direct crane lifting of the tower. Attached Figure Description

Figure 2 This is a front view structural diagram of the offshore wind power installation ship tower limiting device of this utility model in the open state, as shown. Figure 1 and Figure 2 As shown, the offshore wind power installation ship tower limiting device provided in this embodiment includes a tower 1, a base 2, a bearing component, and multiple inner abutment components. The base 2 is fixedly installed on the hull by bolts. The bearing component is set on the base 2. The top of the bearing component can be opened to form a channel for the tower 1 to be inserted. When the bearing component is closed, the bearing component forms a cylindrical structure around the outer periphery of the tower 1. Multiple inner abutment components are evenly distributed on the inner sidewall of the cylindrical structure, and the abutment end of the inner abutment component faces the tower 1.

[0024] In the above embodiment, the bearing assembly includes a lower bearing 3, a left bearing 4, and a right bearing 5. The lower bearing 3 has a semi-circular cross-section and is disposed on the base 2. The left bearing 4 and the right bearing 5 are symmetrically distributed on the left and right sides of the lower bearing 3, and both the left bearing 4 and the right bearing 5 are hinged to the lower bearing 3. When the end of the left bearing 4 away from the lower bearing 3 and the end of the right bearing 5 away from the lower bearing 3 are in contact with each other, the lower bearing 3, the left bearing 4, and the right bearing 5 are combined to form a cylindrical structure surrounding the outer periphery of the tower 1. The end of the left bearing 4 away from the lower bearing 3 and the end of the right bearing 5 away from the lower bearing 3 are both provided with a connecting part.

[0025] In the above embodiment, the connecting part includes two connecting bodies 6. The two connecting bodies 6 are respectively disposed on the outer side of the end of the left support body 4 away from the lower support body 3 and the outer side wall of the right support body 5 away from the lower support body 3. Both connecting bodies 6 are provided with through holes. When the two connecting bodies 6 are fitted together, bolts can pass through the through holes, so that the two connecting bodies 6 are connected to each other.

[0026] In the above embodiment, the inner abutment component includes an abutment block 8 and a telescopic rod 7. The inner sidewall of the cylindrical structure has grooves that correspond one-to-one with the inner abutment component. One end of the telescopic rod 7 is connected to the bottom wall of the groove, and the abutment block 8 is disposed at the other end of the telescopic rod 7. When the telescopic rod 7 is shortened to its shortest state, the abutment block 8 fits exactly against the inner sidewall of the cylindrical structure.

[0027] In the above embodiment, a detachable anti-slip pad is provided on the side of the abutment block 8 away from the telescopic rod 7, and the surface of the anti-slip pad facing the tower 1 is provided with anti-slip texture.

[0028] Working principle: During use, the two connecting blocks are separated, driving the left support body 4 and the right support body 5 away from each other. At this time, the tower 1 can be hoisted and placed in the lower support body 3 by a crane. The left support body 4 and the right support body 5 are covered, so that the two connecting bodies 6 are close to each other and fixed with bolts. At this time, the length of the telescopic rod 7 is adjusted according to the diameter of the tower 1, so that the abutment blocks 8 are close to the outer wall of the tower 1 to restrict the tower 1. The tower 1 can be fixed as a whole by using multiple limiting components. When the tower 1 is transported to the corresponding position, the two connecting bodies 6 are separated, and the left support body 4 and the right support body 5 are driven away from each other, so that the tower 1 can be hoisted by a crane.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the content of the present utility model specification should be included within the protection scope of the present utility model.
