【Detailed ways】

Below in conjunction with accompanying drawing, the utility model is described in detail:

A new type of bottom-mounted offshore fan installation barge, including a sinkable or floating hull 1, the hull 1 is composed of a deck 11 and a bottom 12 that can sink when filling water or float when pumping water. A deckhouse 2 is arranged on one side of the deck 11, and a crane 3 is arranged on the other side, and the crane 3 is a crawler crane, and the crane 3 is fixed on a horizontal device 4 whose horizontal position can be adjusted.

A plurality of pillars 13 are arranged between the deck 11 and the bottom 12 of the ship, and the number of said pillars 13 is four.

Described horizontal device 4 comprises truss 41, is provided with load-bearing beam 42 at both ends of described truss 41, and described load-bearing beam 42 is box type load-bearing beam, is provided with horizontal device on described load-bearing beam 42. 4. A locking device 43 that is locked to the deck 11. A plurality of jacks 44 that can adjust the horizontal position of the horizontal device 4 are arranged under the load-bearing beam 42. The jacks 44 are hydraulic jacks.

Due to the unevenness of the seabed, the crane 3 on the deck 11 will incline after the workboat dives and sits on the bottom, so the leveling device 4 is used to adjust the levelness of the crane. When adjusting, use a hydraulic jack to adjust the platform of the crane 3 to a horizontal state, and then use the locking device 43 to fix it.

The locking device 43 includes a locking member 431, a load-bearing beam connection ear 432 respectively arranged on the load-bearing beam 42 and a deck connection ear 433 arranged on the deck 11, and one end of the locking member 431 is connected to the load-bearing beam. Connect on the remote 432, and the other end is connected on the deck connecting ear 433.

The crane 3 is provided with two boom frames 31 in opposite directions, and a wire rope 32 is arranged between the top ends of the boom frames 31 .

The concrete construction method of the present utility model is as follows:

The utility model is towed to the operation sea area, and after reaching the installation point of the fan, the position of the lifting point is fixed, and the ballast system is used to inject water into the bottom 12 of the ship to make it dive and sit on the bottom. After the horizontal position meets the requirements for hoisting wind power equipment, fix the crane 3, and then use the crane 3 to hoist the fan module or integral hoisting. The next fan hoisting point operation.

Modular hoisting means that each component of the wind turbine, such as the foundation, tower, engine room, wheel shell and fan blades, is transported to the site and then hoisted separately. This situation is mainly for the site sea area conditions that do not meet the overall transportation hoisting. If the sea area is not deep enough, It does not meet the needs of large-scale transport barges; the integral hoisting means that after the wind turbine tower, engine room, wheel shell and wind blades are assembled on land, they are transported by barge to the wind power installation point, and the utility model performs one-time hoisting.
