Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering, and particularly relates to a jack-up wind power installation platform. Background Art

[0002] Wind energy is a rich and environmentally friendly new energy source. The development of wind energy mainly relies on wind power generation. In recent years, the wind power generation industry in China has developed rapidly, and offshore wind power generation has also become an investment direction for wind power generation in China. A wind power installation vessel is a very important component in the construction of an offshore wind farm, mainly used to transport the wind turbine units (generators, blades, and tower barrels) required for an offshore wind farm to a designated installation point and install them, and it is a new type of marine engineering operation vessel.

[0003] In the early days, the installation of offshore wind turbines was mainly carried out by a crane ship or a jack-up platform. With the rapid development of offshore wind power generation, the continuous enlargement of wind turbines, the limitations of lifting capacity and lifting height, and the complication of sea conditions, a ship specially designed for wind turbine installation emerged, combining the advantages of a jack-up platform and a floating ship.

[0004] See Figure 1 , in a traditional wind power installation vessel, the superstructure is located at the bow, and behind the superstructure is the operation deck. At the four corners of the operation deck, there are leg 2, pile shoe 3, lifting mechanism, etc. Usually, a revolving crane is set on one leg 2 at the tail as the main crane for wind power installation operations. In the self-elevating state, the pile shoe 3 touches the bottom, and the whole ship is lifted above the sea surface through the leg 2.

[0005] A traditional wind power installation vessel integrates an installation platform 4 and a floating ship 1. The installation platform 4 and the floating ship 1 are of an integral structure. Integrating the installation platform 4 and the floating ship 1 into one can significantly reduce the influence of sea conditions and improve the stability and reliability of wind power installation operations.

[0006] The above-mentioned traditional wind power installation vessel has the following limitations:

[0007] (1) Because the traditional wind power installation vessel integrates the installation platform 4 and the floating ship 1 and belongs to an integral design, the whole ship lifts synchronously during lifting. Coupled with the necessary variable load on the deck surface, the lifting system capacity of the installation platform is very large.

[0008] (2) Because the traditional wind power installation vessel integrates the jack-up platform 4 and the floating ship 1, and many functions such as the deck operation area and the superstructure are integrated together, the wind power operation deck area cannot be fully exploited.

[0009] Therefore, due to the integral structure of the installation platform of the existing wind power installation vessel with the ship, the above-mentioned defects occur. It can be seen that there is an urgent need to provide an installation platform with an innovative structure for wind power components to solve the above technical defects. Summary of the Utility Model

[0010] In view of the above technical defects existing in the existing wind power installation vessels, the purpose of the present utility model is to provide a jack-up wind power installation platform, which can effectively overcome the technical defects existing in the existing wind power installation vessels by forming a separated structure between the installation platform and the vessel.

[0011] To achieve the above purpose, the present utility model provides a jack-up wind power installation platform. The jack-up wind power installation platform is independently arranged and includes a platform structure and a lifting structure. The lifting structure is distributed at the bottom of the platform structure, and the lifting structure can drive the platform structure and the large crane arranged on the platform structure to lift independently.

[0012] Further, a number of functional modules are cooperatively arranged on the platform structure.

[0013] Further, a power module is also distributed on the platform structure. The power module cooperates with the large crane and the lifting structure respectively to provide working power for the large crane and the lifting structure.

[0014] Further, the platform structure is a barge-type structure.

[0015] Further, a number of notches are distributed on the platform structure, and the notches cooperate with the lifting mechanism.

[0016] Further, the lifting mechanism includes a number of lifting components. The number of lifting components are respectively arranged corresponding to the notches. The lifting components can penetrate the notches and lift relative to the notches.

[0017] Further, the number of lifting components respectively include pile legs, pile shoes, pile fixing chambers and driving members. The pile fixing chambers are communicated with the notches at the bottom. The pile shoes are arranged at the ends of the pile legs to form an integral structure and penetrate through the pile fixing chambers to be arranged with the platform structure, and can move up and down relative to the pile fixing chambers. A rack is arranged on the side surface of the pile legs, and correspondingly, a driving gear is arranged inside the pile fixing chambers. The driving member is arranged inside the pile fixing chambers and cooperates with the driving gear to drive the rotation of the driving gear. When the driving gear rotates, it meshes with the rack to form a transmission component to drive the pile legs to lift.

[0018] The jack-up wind power installation platform provided by the present utility model can be combined with and separated from the vessel during specific implementation. When lifting the wind power components, only the platform structure needs to be lifted. Compared with the existing method of simultaneously lifting the vessel and the platform through a single lifting system, the load of the lifting system is greatly reduced, and the lifting system can be designed more economically.

[0019] Meanwhile, the wind power components can be fully integrated onto the platform structure in this solution. Thus, the deck area of the ship can be fully exploited, effectively solving the technical defects brought about by the integral structure of the existing installation platform and the ship.

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific illustrations.

[0028] The self-elevating wind power installation platform provided by the present utility model is in a separated state from the ship, and forms an independent self-elevating wind power installation platform as a whole. During specific implementation, it can be combined with and separated from the ship. When lifting and lowering the wind power components, only the platform structure needs to be lifted and lowered. Compared with the existing method of simultaneously lifting the ship and the platform through a single lifting system, the load of the lifting system is significantly reduced, and the lifting system can be designed more economically.

[0029] Further, referring to Figure 2 , the self-elevating wind power installation platform 100 includes a platform structure 110 and a lifting structure 120. The lifting structure 120 is distributed at the bottom of the platform structure 110, and the platform structure 110 can be lifted and supported by the drive of the lifting structure 120.

[0030] The platform structure 110 is provided with a plurality of functional modules 130, and functional operations can be realized by providing the plurality of functional modules 130. For example, the plurality of functional modules 130 include but are not limited to a lounge, an office, and a supply cabin.

[0031] Among them, the lounge and office are distributed on the upper surface of the platform structure and can be used for wind turbine installation work, personnel rest and work.

[0032] The supply tank is arranged inside the platform structure 110 and is used to supply the energy required during the installation of the platform. For example, it includes but is not limited to necessary supply tanks such as fuel tanks and fresh water tanks of appropriate capacity that can be arranged inside the platform structure 110.

[0033] At the same time, a power module 140 is distributed on the platform structure 110 . The power module 140 cooperates with the large crane and the lifting structure 120 respectively, and can provide working power for the large crane and the lifting structure 120 .

[0034] For example, the power module 140 includes but is not limited to a generator set, a hydraulic press, etc., which can serve as a power source for the large crane and the lifting structure 120.

[0035] It should be noted here that the separation platform 100 in this solution is preferably a barge-type structure, which is compatible with the ship structure and can be better fitted to ensure reliability after integration.

[0036] The lifting mechanism 120 includes a plurality of lifting components, which are symmetrically arranged at the corners of the platform structure 110. The plurality of lifting components can synchronously drive the installation platform structure 110, and can support and lift the platform structure 110. In some embodiments, see Figure 3 The plurality of lifting components include pile legs 121, pile shoes 122, pile fixing chambers 123 and driving components.

[0037] Specifically, notches are preset on the platform structure 110 , and a pile fixing chamber 123 is correspondingly arranged on each notch, and the pile fixing chamber 123 is communicated with the notch at the bottom.

[0038] The pile shoe 122 is arranged at the end of the pile leg 121 to form an integrated structure. The size of the pile shoe 122 is larger than the pile leg 121. When the pile shoe 122 is inserted into the seabed, it can expand the contact area with the seabed to disperse the load transmitted by the pile leg 121. When the pile shoe 122 cooperates with the pile leg 121, it integrally penetrates the pile fixing chamber 123 and the platform structure 110 and can move up and down relative to the pile fixing chamber 123.

[0039] Among them, a rack 124 is provided on the side of the leg 121. Correspondingly, a driving gear is arranged inside the pile fixing chamber 123. Through the engagement of the rack 124 of the leg 121 with the driving gear in the pile fixing chamber 123, a transmission assembly of the leg 121 can be formed, and the leg 121 can move up and down relative to the pile fixing chamber 123.

[0040] When the leg 121 is lowered, the pile shoe 122 sinks to the bottom, lifts the platform structure 110 through the leg 121, and supports it; when the leg 121 is retracted, the pile shoe 122 moves up to the bottom of the platform structure 110.

[0041] Since the platform structure 110 is located above the ship when combined with the ship, and its pile shoe 122 will not touch the water surface, the resistance caused by the pile shoe 122 being in the water can be avoided. Therefore, when the pile shoe 122 moves up to the maximum limit, it is located at the bottom of the platform structure 110 and does not need to be embedded inside the platform structure 110, avoiding digging a larger groove inside the platform structure 110, thereby causing greater damage to the structural strength. At the same time, the driving member is arranged in the pile fixing chamber 123 and cooperates with the driving gear to drive the movement of the driving gear. When the driving gear moves and meshes with the rack 124, it can drive the lifting and lowering of the leg 121.

[0042] The specific structure of the driving member is not limited in this solution. By way of example, it can be a driving motor or other driving mechanisms, and the specific structure can be selected according to the actual situation.

[0043] Regarding the composition of the lifting and lowering assembly, this solution is not limited to adopting the above structure. By way of example, a lifting and lowering assembly of the plug-in pin type can also be adopted, and the specific selection can be determined according to the actual situation.

[0044] Here it should be noted that referring to Figure 4 , the inner dimension B1 of the symmetrically arranged legs 121 is greater than the ship width B of the mother ship, which is convenient for separating and combining the platform and the mother ship.

[0045] The self-elevating wind power installation platform composed of the above solution can cooperate with the ship 200 and be combined with / separated from the ship 200 during specific applications to realize the construction of wind power components.

[0046] Specifically, first, the driving assembly drives the leg 121 to lower, lifts the platform structure 110 above the height of the ship 200, and then the driving assembly drives the leg 121 to retract. The platform structure 110 descends onto the ship 200 and fits completely with the ship 200. The ship 200 transports the various components of the platform structure 110 connected to the wind power to the construction site.

[0047] After the ship 200 transports the platform structure 110 to the construction site, it is precisely positioned by the mother ship, the pile legs 121 are lowered to the seabed to touch the bottom, and the platform structure 110 and the wind power components arranged on the platform structure 110 are independently lifted. Thus, the platform structure 110 is separated from the ship 200, and the ship 200 can arrange other operations during the installation operation of the platform structure 110.

[0048] The separable self-elevating wind power installation platform composed of the above solution can be combined with and separated from the ship during its specific implementation. When lifting and lowering the wind power components, only the platform structure needs to be lifted and lowered. Compared with the existing method of simultaneously lifting the ship and the platform through a single lifting system, the load of the lifting system is greatly reduced, and the lifting system can be designed more economically.

[0049] At the same time, the wind power components can be fully integrated on the platform structure. Thus, the deck area of the ship can be fully exploited, effectively solving the technical defects brought about by the existing integral structure of the installation platform and the ship.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
