Problems solved by technology

Using multi-point anchoring and building peripheral breakwaters to improve the stability of floating nuclear power plants has obvious effects, but there are great limitations. For some islands and offshore drilling platforms with limited land area, this method is not very suitable. Moreover, in some areas with relatively deep sea water, the engineering volume of building peripheral breakwaters will be greatly increased, resulting in an increase in the total cost of the project, which is not convenient for popularization and application.

Embodiment 1

[0025] like figure 1 As shown, the single point mooring system suitable for hull-type floating nuclear power plants includes pile foundation 1, positioning column 2, rotating platform 3, positioning seat 4 and the connection mechanism connecting rotating platform 3 and positioning seat 4, wherein, in order to ensure that the pile To improve the structural strength of the foundation 1 and reduce the cost, the pile foundation 1 of this embodiment adopts steel pipe and concrete structure. The lower end of the pile foundation 1 is fixed on the seabed, the positioning column 2 is fixed on the pile foundation 1 and is located above the sea level, the rotary table 3 is arranged on the positioning column 2 and can rotate around the center line of the positioning column 2, the positioning seat 4 A common steel connecting seat is used, which is fixed on the hull of the floating nuclear power plant. In the specific setting of this embodiment, limit blocks fixed on the positioning column...

Embodiment 2

[0028] This embodiment makes the following further limitations on the basis of Embodiment 1: the connection mechanism of this embodiment includes a positioning seat connecting piece connected to the positioning seat 4, a rotating table connecting piece connected to the rotating table 3, and a connecting positioning seat The shock-absorbing damping device 5 of the connecting piece and the rotating table connecting piece, in order to ensure the structural strength of both the positioning seat connecting piece and the rotating table connecting piece, both the positioning seat connecting piece and the rotating table connecting piece are constructed of steel pipes.

[0029] When this embodiment is applied, the shock absorbing and damping device 5 can quickly attenuate the up and down, front and back, and left and right shaking of the floating nuclear power plant, which can further improve the stability of the floating nuclear power plant.

Embodiment 3

[0031]This embodiment makes the following further limitations on the basis of Embodiment 2: this embodiment also includes a vertical positioning frame. In order to ensure the structural strength of the positioning frame, the positioning frame adopts a steel pipe structure, wherein the upper and lower parts of the positioning frame are constructed of steel pipes. Both ends are fixed with shock-absorbing and damping devices 5 , the positioning seat connecting piece is connected with the shock-absorbing and damping device 5 fixed on the upper end of the positioning frame, and the rotary table connecting piece is connected with the shock-absorbing and damping device 5 fixed at the lower end of the positioning frame. In this way, when the present embodiment is applied, the shock absorption performance can be further improved through two-stage shock absorption, so that the floating nuclear power plant can quickly maintain stability when subjected to a load.

Abstract

The invention discloses a single-point mooring system suitable for a hull type floating nuclear-powered plant. The single-point mooring system suitable for the hull type floating nuclear-powered plant comprises a pile foundation (1), the lower end of which is fixed in the seabed, a locating post (2) fixed on the pile foundation (1) and located above the sea level, a rotating platform (3) arranged on the locating post (2) and capable of rotating around the central line of the locating post (2), a locating seat (4) fixed on a floating nuclear-powered plant hull body, and a rotating platform (3) and locating seat (4) connecting mechanism. The single-point mooring system suitable for the hull type floating nuclear-powered plant is simple in structure and convenient to implement and popularize; by means of the single-point mooring system suitable for the hull type floating nuclear-powered plant, the floating nuclear-powered plant rotates around the locating post (2) under load so as to reduce shake, and the stability is improved.

Description

technical field [0001] The invention relates to a floating nuclear power plant, in particular to a single point mooring system suitable for a hull type floating nuclear power plant. Background technique [0002] Floating nuclear power plants are built on the sea and are divided into platform-type floating nuclear power plants and ship-type floating nuclear power plants. They can provide heat, electricity, water, and steam for islands, offshore oil drilling platforms, polar regions, and certain special offshore installations. Offshore nuclear facilities are isolated and have limited peripheral auxiliary facilities. Therefore, it is necessary to ensure sufficient stability and safety of the reactor in the nuclear power plant during design. [0003] Russia's KLT-40S floating nuclear power plant adopts a ship-type structure. In order to ensure stability, it is applied close to islands or ports, and adopts multi-point anchoring. Breakwater dikes are built around to prevent the sh...
