The application discloses a kind of floating wind turbine and seabed data center fusion device, including wind turbine, tower drum, float, mooring cable, seabed data center, the wind turbine is arranged on the tower drum, the tower drum is arranged on the float, the float is connected with the mooring cable, the seabed data center and the mooring cable are connected, the seabed data center is as the anchoring base of the float, the seabed data center is below waterline, the wind turbine and the seabed data center are electrically connected.The application can effectively reduce the construction cost of floating wind turbine and seabed data center, reduce the power cost of seabed data center, effectively improve the cooling capacity of seabed data center.

A rope skipping handle with two kinds of rope threading mechanism, it is characterized in that: the rope skipping handle includes a shell unit, a dual-purpose rope threading mechanism, the dual-purpose rope threading mechanism includes a universal positioning shaft, a transverse rope threading locking screw and an axial rope threading one-way locking unit.The beneficial effects of the prior art are that, due to the dual-purpose rope threading mechanism, people can choose any one of the transverse rope threading mode and the axial rope threading mode to complete the rope threading, and the rope threading mode can be changed very conveniently and quickly, thus meeting the needs of most rope skipping users, effectively saving the consumption and waste of the rope skipping, and greatly improving the utilization rate of the rope skipping.

This invention discloses a novel seawater and sea sand recycled concrete base course and its construction method, belonging to the field of transportation engineering. Its characteristics are as follows: the preparation material of the novel base course is a mixture composed of a curing agent, seawater, sea sand, recycled coarse aggregate, and admixtures in a mass ratio ranging from 1~8:0.4~4.2:0.2~6.8:0.4~8.8:0~0.6; the sea sand is a continuously graded fine aggregate such as marine sand and gravel, coral fragments, and shell fragments; the recycled coarse aggregate is a continuously graded coarse aggregate such as waste coral; the curing agent consists of a slowly hydrated cementing component and a rapidly hydrated expansion component that reacts with chloride and sulfate ions in the seawater and sea sand to form expanding hydrates; based on the design strength value of the novel base course, specific compaction machinery, compaction rate, number of compaction passes, and constraint load value are selected; the curing agent, seawater, sea sand, recycled coarse aggregate, and admixtures are mixed evenly in a certain proportion, spread, compacted using a compaction machine, and cured under constraint load for 7 days before the constraint is removed to obtain the novel seawater and sea sand recycled concrete base course.
