Description

Technical Field

[0001] This utility model relates to the field of offshore wind power equipment technology, specifically to a vertical transport and fixed support device for offshore wind power towers. Background Technology

[0002] Offshore wind power refers to a method of power generation that deploys wind power generation equipment at sea. With increasing global demand for clean energy and continuous technological advancements, offshore wind power has experienced rapid development. Particularly in Europe, countries like Germany, the UK, and Denmark have already built large-scale offshore wind farms, while countries like China and the US are actively investing in offshore wind power projects. The development of offshore wind power not only helps reduce carbon emissions and achieve sustainable development but also provides strong support for local energy supply. Maritime transport has advantages such as large ship carrying capacity, low unit transportation costs, and wide transport range, making it a primary mode of transport for heavy equipment such as offshore wind turbine towers. However, maritime transport also faces challenges, such as unstable weather conditions and significant wave-induced undulations, posing challenges to the safe and stable transport of cargo. Therefore, effective fixed support devices are needed during maritime transport to ensure the safety of cargo such as towers.

[0003] In vertical transport of offshore wind turbine towers, the towers need to be placed vertically to save space on the ship and reduce transportation costs. However, existing technologies for fixed support devices for vertical transport of offshore wind turbine towers often have a shorter height to take into account transportation issues. This also brings problems, such as the fact that offshore wind turbine towers are prone to tipping over in strong winds or when the ship is in a large wave, causing safety hazards. Summary of the Invention

[0004] (I) Technical problem to be solved: In view of the shortcomings of the existing technology, this utility model provides a ship vertical transport and fixed support device for offshore wind turbine towers, which has the advantage of effectively reducing the possibility of the tower tilting and falling in strong winds without affecting transportation, and solves the problem of offshore wind turbine towers being easy to tilt in the existing technology.

[0005] (II) Technical Solution: To achieve the above-mentioned objective of effectively reducing the possibility of the tower tilting and falling in strong winds without affecting transportation, this utility model provides the following technical solution: A vertical transport and fixed support device for offshore wind turbine towers, comprising a base, wherein a circular opening is provided at the center of the base to form an installation groove, and the installation groove is used to place the tower to be installed; the inner surface of the installation groove is provided with fixing grooves arranged in an array along its own circumference, the number of fixing grooves being not less than 4; a fixing plate is provided in the fixing groove, and a lifting system is provided below the fixing plate, the lifting system comprising a lifting rod, the upper end of the lifting rod being fixedly connected to the lower end of the fixing plate, the lifting system being controlled by a control system, and the fixing plate having a degree of freedom of movement in the vertical direction.

[0006] Preferably, the lifting system is a hydraulic lifting system, the lower end of the lifting rod is connected to a hydraulic cylinder, and the lifting rod is a multi-stage hydraulic rod.

[0007] Preferably, the lifting system is fixed inside the base by bolts; when the lifting system is not activated, the upper surface of the fixing plate is at the same horizontal height as the upper surface of the base.

[0008] Preferably, the hydraulic cylinder portion of the lifting system is internally designed with a one-way hydraulic valve.

[0009] Preferably, a wind sensor is provided on the outer surface of the base, and the wind sensor is connected to the lifting system.

[0010] Preferably, the base is octagonal; the upper surface of the base is provided with a reinforcing rib structure, and the reinforcing rib structure is distributed in an array along the center of the mounting groove.

[0011] (III) Beneficial Effects: Compared with the prior art, this utility model provides a vertical transport and fixed support device for offshore wind turbine towers, which has the following beneficial effects:

[0012] 1. This type of offshore wind turbine tower vertical transport and fixing support device for ships involves creating a fixing groove on the surface of the mounting slot, placing a fixing plate inside, and connecting the lower end of the fixing plate to a lifting system. When the lifting system is not activated, the upper surface of the fixing plate is at the same horizontal height as the upper surface of the base, ensuring no interference during transportation. This design considers not only practicality but also the smoothness and efficiency of transportation. In severe weather or when the ship is affected by waves and experiences significant swaying, posing a risk of the tower tilting or collapsing, the operator can adjust the lifting system via the control system to move the fixing plate upwards. The fixing plate not only provides an additional support point for the tower but also distributes some of the wind load. The load is effectively distributed to itself, thus greatly reducing the wind load on the tower itself. This change allows the tower to stand more stably on the ship when subjected to wind force, greatly reducing the risk of tilting or collapse. Compared with the existing technology, this utility model device significantly improves the stability of the fixed support device while maintaining smooth transportation. It cleverly utilizes the combination of lifting system and fixed plate to effectively reduce the impact of adverse conditions such as bad weather and ship swaying, making the tower safer and more reliable during transportation. This innovative design not only improves transportation efficiency but also provides strong protection for the safe transportation of offshore wind power towers.

[0013] 2. This type of offshore wind turbine tower ship vertical transport and fixed support device cleverly incorporates a wind sensor on its robust outer surface. This design allows the device to sense and respond to changes in external wind force in real time. Simultaneously, the device uses a highly efficient and stable hydraulic cylinder as the core working component of the lifting system, ensuring precise and reliable lifting actions. More advancedly, a carefully designed one-way hydraulic valve is incorporated internally, and through precise signal connection technology, seamless integration between the wind sensor and the one-way hydraulic valve is achieved. In actual operation, the wind sensor accurately captures and transmits wind force data to the one-way hydraulic valve, which intelligently activates or deactivates based on the received signal type, thereby precisely controlling the height adjustment of the lifting rod and the fixed plate. This innovative design allows the device to flexibly adjust the height and angle of the support frame according to different wind conditions and specific transportation needs, thereby optimizing its support effect on the tower and ensuring the stability and safety of the tower during transportation. Compared with existing technologies, this device not only significantly improves the intelligence level of the fixed support device but also greatly enhances its adaptability to complex environments while maintaining smooth transportation. This innovative design not only improves transportation efficiency but also provides a more robust guarantee for the safe transportation of offshore wind turbine towers. By adding a wind sensor to the outer surface of the fixed support device, using a hydraulic cylinder as the working component of the lifting system, and designing and installing a one-way hydraulic valve inside, a signal connection is established between the two. The wind sensor transmits the signal to the hydraulic valve, which then starts or closes the one-way hydraulic valve, thereby controlling the height of the lifting rod and the fixed plate. Compared with existing technologies, this utility model can optimize the support effect on the tower by adjusting the height and angle of the support according to different wind conditions and transportation needs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 A vertical transport and fixing support device for offshore wind turbine towers includes a base 1. A circular opening is formed at the center of the base 1, creating an installation groove 11. The installation groove 11 is used to place the offshore wind turbine tower; therefore, the inner diameter of the installation groove 11 should be designed according to the outer diameter of the tower to be installed. Fixing grooves 2 are arranged in an array along the circumference of the inner surface of the installation groove 11. The number of fixing grooves 2 is not less than four, but in this embodiment, it is specifically designed as eight. A fixing plate 3 is installed within the fixing groove 2, with the fixing plate 3 tightly attached to the outer surface of the tower on one side. A lifting system 4 is installed below the fixing plate 3. This lifting system 4 is specifically a hydraulic lifting system, including a lifting rod 41 and a hydraulic cylinder 42. The lifting rod 41 is specifically a multi-stage hydraulic rod. The upper end of the lifting rod 41 is fixedly connected to the lower end of the fixing plate 3 by bolts or other means. 4. Under the control of the control system, the fixed plate 3 has a degree of freedom of movement in the vertical direction. Therefore, in actual use, when the lifting system 4 is not activated, the upper surface of the fixed plate 3 and the upper surface of the base 1 are at the same horizontal height, so as not to cause interference during transportation. This not only takes into account practicality, but also takes into account the smoothness and efficiency of transportation. When the weather is bad, or the ship is affected by the waves and the swaying amplitude is large, and the tower is at risk of tilting and collapsing, the user can adjust the lifting system 4 through the control system to make the fixed plate 3 move upward. The fixed plate 3 not only provides an additional support point for the tower, but also effectively distributes some of the wind load to itself, thereby greatly reducing the wind load borne by the tower itself. This change makes the tower more stable on the ship when subjected to wind force, greatly reducing the risk of tilting or collapsing.

[0021] In this embodiment, a one-way hydraulic valve is designed inside the hydraulic cylinder 42 of the lifting system 4. The one-way hydraulic valve can control the height of the lifting rod 41 in the vertical direction by opening and closing. The one-way hydraulic valve is prior art and is not shown in the accompanying drawings.

[0022] Please see Figures 3-4A wind sensor 5 is installed on the outer surface of the base 1. The wind sensor 5 communicates with the lifting system 4, transmitting the wind force conditions of the tower to the lifting system 4. The lifting system 4 then flexibly adjusts the height of the lifting rod 41 via a one-way hydraulic valve. The lifting system 4 is bolted to the inside of the base 1 to ensure the stability of the structure. When the lifting system 4 is not activated, the upper surface of the fixing plate 3 is at the same horizontal height as the upper surface of the base 1, ensuring that transportation is not affected. This device can flexibly adjust the height and angle of the support according to different wind conditions and specific transportation needs, thereby optimizing its support effect on the tower and ensuring the stability and safety of the tower during transportation. Compared with the prior art, this utility model not only significantly improves the intelligence level of the fixed support device, but also greatly enhances its ability to adapt to complex environments while maintaining smooth transportation. This innovative design not only improves transportation efficiency, but also provides a more solid guarantee for the safe transportation of offshore wind power towers. This utility model can optimize its support effect on the tower by adjusting the height and angle of the support according to different wind conditions and transportation needs.

[0023] Please see Figures 1-3 The base 1 is octagonal; the upper surface of the base 1 is provided with a reinforcing rib structure 6, which is arranged in an array along the center of the mounting groove 11, so that the force on the tower can be evenly distributed to the base 1, ensuring the stability of the equipment.
