1 , 2 , 32 , and 33 , the mooring assembly 30 includes a main cable 31 connected to the center of the buoy 10 and auxiliary cables 32 scattered around the main cable 31 .

Both ends of the main cable 31 are respectively connected to the center and the base of the floating platform 10. The main cable 31 is used to ensure that the floating platform 10 can provide sufficient traction under various sea conditions, so that the floating platform 10 is close to the water surface.

The main cable 31 plays a role in positioning the floating platform 10, providing main longitudinal traction force and part of the horizontal direction traction force in stormy weather.

When the water level of the floating platform 10 is relatively low and the wind and waves are small, it only needs a small traction force to play the role of positioning. When the floating platform 10 encounters wind and waves, it needs a larger traction force to ensure 10 has a relatively stable position and a safe state.

If the stability of the main cable 31 itself is relatively poor, when floating encounters stormy weather, the buoyant platform 10 will produce greater shaking, and be controlled by the wind and waves to cause a relatively large position shift, which will affect the normal operation of the photovoltaic unit 11 on the floating platform 10.

In order to solve the above-mentioned problems, a plurality of loads 3101 are scattered along the length of the main cable 31. The loads 3101 have a certain gravity. When the wind and waves are large, they can provide stability to the floating platform 10 and reduce the position of the floating platform 10. Moving, providing horizontal restoring force and vertical traction force, preventing the floating platform 10 from being overturned under huge wind and waves.

The main cable 31 is in a vertical position under no wind and wave sea conditions, and only provides vertical traction. When the floating platform 10 deviates from the equilibrium position due to environmental influences, the attitude of the main cable 31 changes and becomes a catenary shape, which can provide horizontal restoring force Resist the impact of environmental loads, and the greater the vertical and horizontal position changes of the buoyant platform 10, the greater the restoring force that the main cable 31 can provide, so that the movement state of the buoyant platform 10 is limited to the greatest extent.

In order to reduce the resistance generated by the load 3101 in the water, the load 3101 is designed as a spherical shape, and its peripheral side is smooth to reduce the resistance.

In order to make the force of the load 3101 on the main cable 31 uniform, the center of the design load 3101 is formed with a through connection hole, the main cable 31 passes through the connection hole, and the load 3101 is placed on the main cable through the limiting part on the main cable 31. The position on 31 is limited.

Auxiliary cables 32 are scattered around the main cables 31, specifically located between the center and sides of the buoy 10, to provide part of the horizontal traction in stormy weather and to prevent the platform from deflecting under normal working conditions. .

Due to the relatively large traction force of the main cable 31 on the floating platform 10, the traction force is concentrated on one point, which is likely to have a negative impact on the free state of the floating platform 10, and the structural strength requirements for the connection with the floating platform 10 are also relatively high. Under these conditions, there is a risk of damage to the connection.

In some embodiments of the present application, in order to solve the above problems and disperse the force between the main cable 31 and the buoy 10, one end of the main cable 31 connected to the buoy 10 is connected with a plurality of fixed ropes through the intermediate transfer part 33 Section 35, each fixed rope section 35 is scattered and formed around the center of the floating platform 10.

The plurality of fixed rope segments 35 can disperse the pull of the main cable 31 on the floating platform 10 , improve the stability of the floating platform 10 and reduce the damage to the floating platform 10 caused by the traction force.

The fixed rope section 35 is made of polyester fiber material with good elasticity and steel cable, which not only achieves the purpose of dispersing the traction force, but also reduces the hindrance of the mooring force to the free floating state of the floating platform 10 as much as possible.

The auxiliary cable 32 is connected between the buoyancy platform 10 and the base in a catenary connection mode. The auxiliary cable 32 and the buoyancy platform 10 can be directly connected, or similar to the main cable 31, also through a plurality of fixed rope segments 35, Distributed connection on the floating platform 10, to disperse the pulling force to the floating platform 10, improve stability.

Referring to Fig. 1 and Fig. 2 again, a kind of implementation of the mooring assembly 30 is: each auxiliary cable 32 is connected with an auxiliary branch rope 3201 through the peripheral side transfer part 34, and the other end of the auxiliary branch rope 3201 is connected to the middle transfer part 33 on.

The auxiliary cable 32 and the auxiliary branch rope 3201 work together to limit the freedom of rotation of the floating platform 10 in the horizontal direction. Resilience.

In the working state, the intermediate transition part 33 can not only disperse the traction force provided by the main cable 31 to each fixed rope section 35, but also transfer the horizontal restoring force provided by the auxiliary cable 32 to the fixed rope section 35, and then act on the floating platform. 10, the concentration of traction force is avoided to the greatest extent, and when the floating platform 10 deviates from the equilibrium position under the environmental load, the resistance force or moment required for the balance is provided for the floating platform 10.

Referring to Fig. 33 again, there are a plurality of corner cable groups 36 on the outside of the auxiliary cables 32, specifically located on the outer edge of the buoyant platform 10. And prevent the floating platform 10 from breaking away from the sea surface in wind and waves.

Each corner cable set 36 comprises two corner cables, including a first corner cable 3601 and a second corner cable 3602, an angle is formed between the first corner cable 3601 and the second corner cable 3602, and the first side A triangular structure is formed between the corner cables 3601 and the second corner cables 3602 and the base to improve the stability of their connection and fixation.

The base can be the seabed, and the fixed pile 37 is preset on the seabed.

In addition, the base can also be a fixed abutment preset on the seabed. In this state, the fixed abutment is pre-buried on the seabed through a plurality of stabilizing frames, and the fixed pile 37 is preset on the fixed abutment. The main cable 31, The auxiliary cable 32 and the corner cable group 36 are directly connected to the fixed base through the fixed stake 37 .

The lower surface of the floating platform 10 is provided with a plurality of connecting parts, and each fixed rope segment 35 , each auxiliary cable 32 and each corner cable are respectively hinged on the corresponding connecting parts.

Specifically, the connection part can be a universal ball structure, so that it has a flexible degree of freedom, reduces the pulling between the corner cables, each auxiliary cable 32 and each fixed rope segment 35 and the floating platform 10, and increases its service life.

In some embodiments of the present application, the horizontal section of the floating platform 10 is a quadrilateral structure, the number of fixed rope segments 35 is four, and an angle of 9 degrees is formed between adjacent fixed rope sections 35 and the connection positions of the floating platform 10, and The connecting line between the connection positions of the adjacent fixed rope segments 35 and the buoyant platform 10 forms an angle with the side of the corresponding buoyant platform 10 .

Correspondingly, the number of auxiliary cables 32 is also four, and each auxiliary cable is arranged on the diagonal of the floating platform 10, and the auxiliary cables 32 and the fixed cables are interlaced to improve its stability.

The tops of each corner cable group 36 are respectively connected to the four corners of the floating platform 10, and the corner cables are similar to the auxiliary cables 32, and are connected below the floating platform 10 in a catenary-type connection.

In order to ensure the structural strength of the mooring assembly 30, the length and strength of the main cable 31 are greater than the auxiliary cables 32 and the corner cables.
