Problems solved by technology

[0003] The seabed construction of traditional pile foundations for offshore wind power generation is more complicated, and the investment cost of infrastructure is much higher than that of onshore wind farms, and the recovery of funds is relatively slow. Occupies a large area of ​​offshore space, causing inconvenience for ships; sea farming often uses cage culture, which is easily disturbed by wind and waves, causing losses; it usually requires a large cost to build an ideal breeding place and the infrastructure of cages

Embodiment Construction

[0013] Below in conjunction with referring to accompanying drawing, the present invention is described in detail:

[0014] Such as figure 1 As shown, a gravity offshore fan foundation includes a fan 1, a tower 2 and a gravity foundation 3, the fan 1 is installed on the top of the tower 2, the tower 2 is fixed on the top of the central column of the gravity foundation 3, and includes a breeding Net cage 4, culture net cage 4 are fixedly attached on the peripheral column of gravity type foundation 3, and culture net cage 4 sizes are gravity type foundation 3 internal spaces.

[0015] Such as figure 2 As shown, the top of the central column 3-1 supports the tower tube 2, and the upper and lower ends of the central column 3-1 are respectively connected by 6 connecting beams 3-3 to 6 peripheral columns 3-2, and the central column 3-1 itself is a steel structure. Guaranteed its support strength. The 6 peripheral columns 3-2 are distributed around the central column 3-1 in a regu...

Abstract

The invention discloses a gravity offshore wind turbine foundation. The gravity offshore wind turbine foundation comprises a wind turbine (1), a tower drum (2) and a gravity foundation body (3). The wind turbine (1) is mounted at the top end of the tower drum (2). The tower drum (2) is fixed to the top of a central stand column of the gravity foundation body (3). The gravity offshore wind turbinefoundation further comprises an aquaculture net cage (4). The aquaculture net cage (4) is fixedly attached to peripheral stand columns of the gravity foundation body (3). The size of the aquaculture net cage (4) is the size of the internal space of the gravity foundation body (3). The gravity offshore wind turbine foundation has the advantages that the stability of the wind turbine foundation is improved, transportation and mounting are facilitated, wind filed fish-farming can also be achieved, and the utilization rate of the unit sea area is increased.

Description

technical field [0001] The invention belongs to the field of offshore wind power generation and the technical field of offshore aquaculture, and in particular relates to a gravity type offshore fan foundation. Background technique [0002] With the introduction of measures such as reducing carbon emissions and transforming the mode of economic development, my country's wind power industry has great prospects for development. my country has further increased its support for the development of the offshore wind power industry through policy regulation and vigorously developed offshore wind power technology. [0003] The seabed construction of traditional pile foundations for offshore wind power generation is more complicated, and the investment cost of infrastructure is much higher than that of onshore wind farms, and the recovery of funds is relatively slow. Occupies a large area of ​​offshore space, causing inconvenience for ships; sea farming often uses cage culture, which...
