The fan pre-installation area on the right side and other areas are arranged, the assembly requirements of all parts of the fan unit shown in the figure 4 are met, meanwhile, the assembly parts can be installed at the wharf side, and the problem of troublesome installation caused by high installation height and complex process of the fan unit is solved.

What needs to be specially stated here is that the area on the right side includes two berths, namely a first wind power special berth and a second wind power special berth, the two berths both stop a fan installation transport ship, and the design ship type of the wind power special berth is generally a professional barge below 20000t level; a tug operation area is arranged in the middle, the area of the tug operation area meets the requirement that the tug drags and pushes the composite cylinder foundation into a U-shaped groove of the transport ship, because if the tug operation area is not arranged in the middle of a shoreline berth, when two wind power special berths stop a fan installation transport ship, a middle clamping groove cannot fix the foundation, the method for solving the problem can only be used for driving the fan installation transport ship out of the berth to rotate and turn around to fix the foundation at the other end after a fan body is installed at one end of the fan installation transport ship, and the unbalanced load ship has higher difficulty and extremely high danger in the rotating process; the utility model provides a setting can make full use of tow boat operation area work simultaneously in the special berth of first wind-powered electricity generation and the special berth of second wind-powered electricity generation, has also guaranteed the fixed to the fan basis.

And another factor is that each fan installation transport ship is provided with two U-shaped grooves, a composite cylinder foundation can be clamped in each U-shaped groove, the fixed crane can complete the assembly of a group of fan bodies nearby, the transport ship can be moved only in the corresponding wind power special parking area, the assembly of the composite cylinder foundation at the other end can be realized, and the installation efficiency is greatly improved.

After whole pier carries out the plane arrangement, still need match the hoist and mount technology to make whole assembly process high-efficient, this application has proposed based on the hoist and mount technology of marine compound section of thick bamboo basis fan whole shipment pier plane arrangement specifically includes following step:

step S1: the cargo ship bearing the steel plates, the gravels and other raw materials is stopped in the universal berth, the portal crane is started to unload the steel plates and the gravels to the transport vehicle, and the transport vehicle is conveyed to the steel storage yard and the gravel storage yard along the road of the field area.

Step S2: the production and processing of the composite cylinder foundation comprises the following specific steps:

step S21: performing primary processing on raw materials such as steel plates, sand stones and the like in a processing area, respectively transferring the raw materials to a fan foundation steel cylinder production line and a fan foundation reinforced concrete cylinder production line after the primary processing, and prefabricating a steel cylinder body and a concrete cylinder body which form a composite cylinder foundation;

step S22: a steel cylinder barrel prefabricated by a fan foundation steel cylinder production line is transversely moved to a foundation assembly area through a module vehicle or an air bag;

step S23: starting a gantry crane, and hoisting the concrete cylinder prefabricated by the fan foundation reinforced concrete cylinder production line to a foundation assembly area;

step S24: and adjusting the gantry crane, hoisting the concrete cylinder to the position above the steel cylinder, jointing the concrete cylinder and the steel cylinder in a joint manner, and then performing hook-drop welding to form the composite cylinder foundation.

Step S3: transporting the machined and molded composite cylinder foundation to a transport ship, and respectively clamping the composite cylinder foundation in U-shaped grooves at two ends of the transport ship; as shown in fig. 5, the specific steps include:

step S31: starting the gantry crane again, hoisting the composite cylinder foundation to a draught fan foundation launching area, slowly dropping the hook, sinking the composite cylinder foundation to an underwater beach surface for debugging, pressurizing the composite cylinder foundation after debugging is finished, and separating the foundation floating from the beach surface;

step S32: the tugboat carries the composite barrel foundation after debugging to a transport ship in a towing manner, the composite barrel foundation is respectively clamped in U-shaped grooves at two ends of the transport ship and is fixed and decompressed after being clamped in the U-shaped grooves until the composite barrel foundation sinks to a mud surface, and the composite barrel foundation (11) is stable and does not shake when a fan unit (12) is installed.

Step S4: and (3) transporting the component tower 1201, the engine room and the blades 1203 to a fan pre-installation area from a fan component storage yard through a module vehicle for pre-installation to form a fan assembly component.

Step S5: and transporting the fan assembly components from the fan pre-installation area to a temporary stacking area through the module vehicle.

Step S6: assembling the fan unit component with a composite cylinder foundation clamped in a U-shaped groove at one end of a transport ship to form a fan body;

the method comprises the following specific steps: step S61: adjusting the position of the transport ship in the special wind power berth, and placing a composite cylinder foundation clamped in a U-shaped groove at one end of the transport ship under a fixed crane;

step S62: starting a fixed crane, vertically hoisting the tower barrel arranged in the temporary stacking area, slowly translating the tower barrel to the top of the composite barrel foundation after the hoisting height reaches the top of the composite barrel foundation, and fastening the tower barrel bottom flange and the top flange of the composite barrel foundation through bolts after butting;

step S63: continuously starting the fixed crane, vertically lifting the engine room arranged in the temporary stacking area, continuously lifting the lifting height until the tower barrel is lifted, horizontally moving to the top of the tower barrel, fastening the flange at the bottom of the engine room and the flange at the top of the tower barrel through bolts after butting, yawing the engine room after fastening, and enabling the axis direction of the engine room to be parallel to the X-axis direction;

step S64: and continuously starting the fixed crane, horizontally hoisting the first blade arranged in the temporary stacking area, inserting the blade into the engine room hub, fastening through the bolt, turning the engine room hub after fastening, and repeatedly installing the blades until all the blades are installed.

Step S7: pressurizing the composite cylinder foundation to enable the fan body to float, and completing a set of pre-assembled ship of the fan body;

what needs to be explained here is that the composite cylinder foundation is pressurized, namely, the air pressure is added in the steel cylinder body, the principle of the composite cylinder foundation is similar to that of a submarine, the cylinder can float after the air pressure is added in the cylinder, and the cylinder can sink after the air pressure is reduced.

Step S8: and moving the position of the transport ship in the special berth for wind power, and assembling the fan unit component and the composite cylinder foundation clamped in the U-shaped groove at the other end of the transport ship to complete the preassembly ship of the next set of fan body.

Above can know, the floor plan and hoist and mount technology of this application have foresight nature, and not only make full use of pier arranges along the line, closely links up each region, carries out the pipelining operation at manufacturing and equipment part, and speed is showing and is improving, and the self characteristic of the fan body of fully combining simultaneously is launched directly at the equipment place, and process flow is simple and convenient.
