Description

Technical Field

[0001] The present invention relates to the technical field of fan installation, and in particular to a fan installation system and method based on movable fan installation equipment. Background Art

[0002] In recent years, with the continuous growth of global demand for clean energy, the development of offshore wind power has continued to increase, and wind turbine towers and blades have tended to be larger in size and weight. However, traditional lifting resources are not highly compatible with current construction scenarios.

[0003] In the field of offshore wind turbine installation, existing installation equipment has many shortcomings. In traditional methods, different equipment is often required for wind turbine installation at the dock and offshore, which not only increases the equipment cost, but also makes the equipment conversion process cumbersome and inefficient. At the same time, due to the differences in operation methods and precision control of different equipment, the quality of wind turbine installation is also affected to a certain extent. In addition, some existing installation equipment has poor flexibility and adaptability when dealing with complex offshore environments and different types of floating foundations, and it is difficult to meet the needs of efficient and accurate installation of wind turbines. Summary of the invention

[0004] The main purpose of the present invention is to provide a wind turbine installation system based on a movable wind turbine installation device, by which the movable wind turbine installation device is moved on the dock or between the dock and the ship's track, so as to realize flexible switching of the equipment on the dock and the ship, improve installation efficiency, reduce costs, ensure installation accuracy, and adapt to different offshore environments and floating foundations. At the same time, the present invention also proposes a method for installing dock wind turbines and offshore wind turbines using the system.

[0005] The technical solution adopted by the present invention is:

[0006] A wind turbine installation system based on a movable wind turbine installation device comprises a track device installed on a dock and the movable wind turbine installation device; the track device comprises a first track and a second track, the first track is arranged on the dock in a longitudinal direction, the second track is arranged on the dock in a transverse direction, the first track and the second track are connected through a curve and can perform a track change operation to realize the turning of the movable wind turbine installation device between different tracks; the movable wind turbine installation device comprises a main frame, a wind turbine installation frame and a moving device, the wind turbine installation frame is installed on the main frame and is used to hold and lift the wind turbine, and the moving device is installed at the bottom of the main frame and is used to drive the movable wind turbine installation device to move along each track as a whole.

[0007] In the above solution, the wind turbine installation system also includes a wind turbine installation vessel; a third track is installed on the wind turbine installation vessel, and the third track can be docked with the first track.

[0008] In the above scheme, the fan mounting frame is installed on one side of the main frame, and includes a lifting device, a hydraulic telescopic rod and a clamp. One end of the hydraulic telescopic rod is installed on the lifting device, and the other end is installed with the clamp. The hydraulic telescopic rod can be extended and retracted. The lifting device drives the hydraulic telescopic rod to move to a suitable height and cooperates with the hydraulic telescopic rod to extend and retract itself to a suitable length, and then opens or closes the clamp to complete the lifting or lowering of the fan.

[0009] In the above solution, a counterweight plate is installed on the other side of the main frame for filling the counterweight.

[0010] In the above solution, the third track is arranged along the longitudinal direction of the wind turbine installation ship and close to the side.

[0011] In the above solution, the moving device is connected to the main frame via a steering gear.

[0012] In the above solution, the second track is arranged close to the shore of the wharf.

[0013] Correspondingly, based on the above-mentioned fan installation system based on the movable fan installation device, the present invention also proposes a method for installing a dock fan, comprising:

[0014] Complete the overall assembly of the wind turbine at the dock;

[0015] The movable fan installation equipment moves along the first track to the side of the fan, adjusts the hydraulic telescopic rod to a suitable height through the lifting device of the fan installation frame, and adjusts the clamp to a suitable position to hold the fan by extending and retracting the hydraulic telescopic rod to complete the loading of the fan;

[0016] The movable wind turbine installation device moves along the first track and then changes track through a diverter to drive into the second track;

[0017] The floating foundation is docked at the pier, and the movable wind turbine installation equipment moves along the second track to the side of the floating platform. The position of the wind turbine is adjusted by telescopic rods of the wind turbine installation frame. When the bottom of the wind turbine reaches the position directly above the floating foundation, the lifting device of the wind turbine installation frame drives the telescopic rod to descend so that the wind turbine and the floating foundation are docked.

[0018] The fan mounting bracket clamps are released from the fan, and the installation of the dock fan is completed.

[0019] Accordingly, based on the above-mentioned wind turbine installation system based on the movable wind turbine installation device, the present invention further proposes an offshore wind turbine installation method, comprising:

[0020] Complete the overall assembly of the wind turbine at the dock;

[0021] The movable fan installation equipment moves along the first track to the side of the fan, adjusts the hydraulic telescopic rod to a suitable height through the lifting device of the fan installation frame, and adjusts the clamp to a suitable position to hold the fan by extending and retracting the hydraulic telescopic rod to complete the loading of the fan;

[0022] The wind turbine installation ship is docked at the pier so that the third track is docked with the first track. The movable wind turbine installation equipment is moved along the first track to the wind turbine installation ship to complete the loading, and then moved along the third track to the mid-ship position.

[0023] The wind turbine installation ship sails to the installation sea area. When the wind turbine installation ship reaches the docking position, the movable wind turbine installation equipment moves on the third track to the side of the floating foundation. The position of the wind turbine is adjusted by telescopic rods of the wind turbine installation frame. When the bottom of the wind turbine reaches the position just above the floating foundation, the lifting device of the wind turbine installation frame drives the telescopic rod to descend so that the wind turbine and the floating foundation are docked.

[0024] The wind turbine mounting bracket clamp is released and the wind turbine is unloaded from the ship, completing the installation of the offshore wind turbine.

[0025] Further optimization: after the wind turbine is lifted, the hydraulic telescopic rod of the wind turbine mounting frame is coordinated and controlled. According to the tilt direction and degree of the movable wind turbine mounting equipment, the telescopic amount of the hydraulic telescopic rod is adjusted to maintain the overall stability of the movable wind turbine mounting equipment.

[0026] After the wind turbines are loaded on board and during the docking process of offshore wind turbines, the ballast water regulation system of the wind turbine installation ship is used to adjust the ship's buoyancy to keep the ship stable.

[0027] The beneficial effects produced by the present invention are:

[0028] 1. Reduced equipment cost: The wind turbine installation system of the present invention can meet the installation requirements of docks and offshore wind turbines based on only one movable wind turbine installation device, thereby reducing equipment cost and having good economic benefits.

[0029] 2. Improved installation efficiency: The movable fan installation equipment of the present invention can be quickly switched on the dock, or between the dock and the ship, reducing the equipment conversion time. At the same time, during the installation process, the synergistic effect of the lifting device, hydraulic telescopic rod and clamp can quickly and accurately complete the installation of the fan, greatly improving the overall installation efficiency.

[0030] 3. Ensure installation accuracy: Through the movement of the movable fan installation equipment on each track and the precise control of the height and length of the hydraulic telescopic rod, the position accuracy and verticality of the fan during the installation process can be ensured, thereby improving the quality of the fan installation.

[0031] 4. Enhanced adaptability: Compared with the traditional lifting equipment frame, the main frame of the movable wind turbine installation equipment uses a triangular structure as the supporting unit to enhance the ability to resist deformation in all directions, effectively resist external forces at sea and reduce the possibility of shaking. Its design makes the center of gravity lower, further improves stability, and is easier to adapt to different types of floating foundations and complex offshore environments.
