A giant airliner structure, comprising a fuselage and at least two upper and lower layers of wings arranged on two sides of the fuselage, wherein a rudder (8) is provided between the adjacent upper and lower wings.
Disclosed in the present invention is a floating wind power system. At least three wind turbines form a wind power generation system by means of pontoons that are integrally connected; the plurality of pontoons are connected end to end to form a high-strength floating platform having a triangular structure or a rectangular structure; a stabilizing structure is provided between at least two pontoons; the stabilizing structure comprises at least one truss structure; a tower base is arranged on at least two connected pontoons; and a plurality of fixed traction devices are arranged on the high-strength floating platform. In the floating wind power system of the present invention, at least three wind turbines are arranged to be combined with a high-strength floating platform consisting of a plurality of pontoons that are integrally connected, to form a wind power generation system, wherein the span of the high-strength floating platform is greater than or equal to the height of a wind turbine tower; moreover, by designing a large-span structure, an offshore wind turbine can be effectively prevented from capsizing, and is enabled to only incline at a limited angle. The floating wind power system also realizes large‑scale power generation from deep‑water offshore wind by means of a multi-turbine arrangement and the design of a modular floating platform.

DOUBLE-LAYER WIND TURBINE BLADE AND MODULAR WIND POWER SYSTEM
A double-layer wind turbine blade, comprising at least two blades (31) arranged up and down. The upper and lower blades (31) are connected by means of a support body to form a truss structure, so that the double-layer wind turbine blade has a bending resistance more than three times the bending resistance of a single blade. In addition, the present invention further relates to a modular wind power system comprising the double-layer wind turbine blade.

A blade (1) having a pull cable, which comprises a resistive rod and a pull cable; the resistive rod extends outwards along the left and right sides and/or the front and rear sides of the blade (1); and the pull cable is arranged between the resistive rod and the blade (1).
A balance control method based on a counterweight movement of a counter-jib of a tower crane, comprising the following steps: S1, acquiring a boom moment and a counter-jib moment of the tower crane; S2, acquiring the position of a counterweight trolley for the counter-jib on the basis of the boom moment and the counter-jib moment, and automatically adjusting the position of the counterweight trolley on the basis of a working state of the tower crane; and S3, determining that, when the difference between the boom moment and the counter-jib moment is greater than a high threshold, a counterweight frequency inverter of the counter-jib drives an alternating current motor to move at a high speed; when the difference between the boom moment and the counter-jib moment is greater than a medium threshold, the counterweight frequency inverter of the counter-jib drives the alternating current motor to move in a medium speed; when the difference between the boom moment and the counter-jib moment is greater than a low threshold and less than the medium threshold, the counterweight frequency inverter of the counter-jib drives the alternating current motor to move at a low speed; and when the difference between the boom moment and the counter-jib moment is less than the low threshold, the tower crane is in a balanced state, and all moving devices remain unchanged.
A segmented wind turbine blade, comprising a blade body (1), which is divided into at least two blade segments (2) in a lengthwise direction, wherein each blade segment (2) is designed to be of a segmented structure in a transverse direction, and can be disassembled for separate transportation. Blade heads of all the blade segments (2) of the whole blade body (1) can be stacked to form a blade head transport unit, and similarly, blade bodies and blade tails are also distributed to form a blade body transport unit and a blade tail transport unit, such that only three containers are needed for transportation of the whole blade body by sea or land, thereby greatly reducing the transportation cost and improving the transportation efficiency. In addition, the present invention further relates to a transportation method for the segmented wind turbine blade.
An automatic climbing crane, comprising a crane body (1) and a crane platform (2) arranged on an upper portion of the crane body (1). The crane body (1) is provided with a plurality of holding mechanisms (4), which are arranged spaced apart from each other, and a driving mechanism for climbing, which is configured to control the crane body (1) to climb up and down along a support body, wherein each holding mechanism (4) comprises a gripper (41) and a gripper driving mechanism which is configured to control the gripper (41) to open and close; and an opening and closing end of the gripper (41) is provided with a pin (7) allowing the gripper (41) to lock the support body. On the one hand, the crane can prevent a self-climbing crane from falling, thereby greatly improving the safety; and on the other hand, the crane can make the holding mechanisms be stably supported when operating, thereby improving the safety and stability of the self-climbing crane.
