With the continuous advance of the development process of the offshore resources, different application scenes need to realize different functions by corresponding platforms. The floating platform adopted in the photovoltaic system is mainly used for supporting the photovoltaic unit and carrying the instrument, and aiming at different sea conditions, the floating platform is always clung to the sea surface when coping with various water environments such as flood tide, ebb tide and wind wave resistance, and meanwhile, larger horizontal displacement and angle change can not occur, and a relatively stable space position is always maintained.
Example 1
As shown in fig. 1, the present application proposes a mooring device for an offshore floating platform, comprising a floating platform 100 for carrying an instrument, supporting a photovoltaic unit, and a mooring component for connecting the floating platform 100 stably.
The mooring component mainly serves to position and ensure that the floating platform 100 can operate normally under any sea condition in the offshore photovoltaic project.
The mooring assembly connects the floating platform 100 to the substrate 200, and in particular, the mooring assembly comprises a main line 300 and an auxiliary line 400.
The main cable 300 is connected to the central position of the floating platform 100 and the base 200 at both ends thereof, and the main cable 300 is used to ensure that sufficient traction force can be provided to the floating platform 100 under various sea conditions so that the floating platform 100 is closely attached to the water surface.
When the water level of the environment where the floating platform 100 is located is relatively low, the wind wave is small, so that the floating platform can play a role in positioning only by needing small traction force, and when the floating platform 100 encounters stormy weather, the floating platform 100 can be ensured to have a relatively stable position and a safe state by needing larger traction force.
If the stability of the main cable 300 is poor, the floating platform 100 will generate larger swaying when the floating is in stormy weather, and the floating platform 100 is controlled by the stormy waves to generate larger position movement, so that the normal operation of the photovoltaic units on the floating platform 100 is affected.
In some embodiments of the present application, in order to solve the above-mentioned problems, the main cable 300 is formed with a plurality of loads 320 along its length direction, the loads 320 have a certain gravity, when the wind wave is large, stability is provided to the floating platform 100, the position movement of the floating platform 100 is reduced, horizontal restoring force and traction force in the vertical direction are provided, and the floating platform 100 is prevented from being lifted under the huge wind wave.
When the floating platform 100 deviates from the balance position due to the environmental influence, the posture of the main cable 300 changes to be changed into a catenary shape, the horizontal restoring force can be provided to resist the influence of environmental load, and the larger the position change of the floating platform 100 in the vertical direction and the horizontal direction is, the larger the restoring force can be provided by the main cable 300, so that the motion state of the floating platform 100 is limited to the greatest extent.
In some embodiments of the present application, to reduce the drag of the load 320 in water, the load 320 is designed in a spherical shape with smooth sides and reduced drag.
In order to make the acting force of the load 320 on the main rope 300 uniform, a through connection hole is formed at the center of the load 320, the main rope 300 passes through the connection hole, and the position of the load 320 on the main rope 300 is defined by a limit part on the main rope 300.
The auxiliary ropes 400 are dispersedly disposed at the circumferential side of the main rope 300, particularly at a position between the center and the side of the floating platform 100, and function to provide a partial horizontal traction in stormy weather and prevent the platform from being deflected in a normal operation state.
Because the main cable 300 has relatively large traction force on the floating platform 100, the traction force acts on a point in a concentrated manner, which easily has a negative effect on the free state of the floating platform 100, and the requirement on the structural strength of the connection with the floating platform 100 is relatively high, and the risk of damage to the connection is easily caused under severe conditions.
In some embodiments of the present application, in order to solve the above-mentioned problems, the acting force between the main cable 300 and the floating platform 100 is dispersed, and a plurality of fixed rope portions 311 are connected to one end of the main cable 300 connected to the floating platform 100 through an intermediate transfer portion 310, and each fixed rope portion 311 is dispersed around the center of the floating platform 100.
The plurality of fixed rope portions 311 may disperse the traction of the main rope 300 on the floating platform 100, improve the stability of the floating platform 100, and reduce the damage of the traction force on the floating platform 100.
The fixed rope portion 311 is made of a polyester fiber material with better elasticity and is compounded with the steel cable, so that the purpose of dispersing traction force is achieved, and the obstruction of mooring force to the free floating state of the floating platform 100 is reduced as much as possible.
The auxiliary cable 400 is connected between the floating platform 100 and the base 200 in a catenary connection manner, and the auxiliary cable 400 and the floating platform 100 can be directly connected, or can be connected to the floating platform 100 in a dispersed manner through a plurality of fixed rope portions 311 similar to the main cable 300, so as to disperse the traction force to the floating platform 100 and improve the stability.
Example 2
Referring to fig. 2, in the present embodiment, each auxiliary rope 400 is connected to an auxiliary stay 610 through a circumferential adapter 600, and the other end of the auxiliary stay 610 is connected to the intermediate adapter 310.
In the working state, the intermediate transfer part 310 not only can disperse the traction force provided by the main rope 300 to each fixed rope portion 311, but also can transmit the horizontal restoring force provided by the auxiliary rope 40 to the fixed rope portions 311, thereby acting on the floating platform 100, avoiding concentration of traction force to the greatest extent, and providing the floating platform 100 with the resistance force or moment required for balancing when the floating platform 100 deviates from the balance position under the environmental load.
Example 3
Referring to fig. 3, on the basis of embodiment 1, a plurality of corner cable sets 500 are further disposed on the outer side of the auxiliary cable 400, specifically located at the outer edge of the floating platform 100, and mainly used to ensure that the floating platform 100 will not deviate at a large angle, affect the working state of other part of the cables, and prevent the floating platform from being separated from the sea surface in stormy waves.
Each corner cable set 500 includes two corner cables, including a first corner cable 510 and a second corner cable 520, where an included angle is formed between the first corner cable 510 and the second corner cable 520, and a triangle structure is formed between the first corner cable 510 and the second corner cable 520 and the base 200, so as to improve the connection and fixation stability.
Referring to fig. 4, the base 200 is provided with a plurality of fixing piles 210, and the main cable 300, the auxiliary cable 400, and the corner cable set 500 are respectively connected to the corresponding fixing piles 210.
The base 200 may be a seabed where the anchor piles 210 are preset.
In addition, the base may be a fixed base preset on the seabed, in which state the fixed base is pre-buried on the seabed through a plurality of fixing frames, the fixing piles 210 are preset on the fixed base, and the main cable 300, the auxiliary cable 400 and the corner cable set 500 are directly connected to the fixed base through the fixing piles 210.
Referring to fig. 5, the lower surface of the floating platform 100 is provided with a plurality of connection parts 110, and each of the fixing rope portion 311, each of the auxiliary ropes 400, and each of the corner ropes are respectively hinged to the corresponding connection parts 110.
The connection portion 110 may be specifically a universal ball structure, so that it has flexible degrees of freedom, and reduces the pulling between the corner cables, the auxiliary cables 400, and the fixed rope portions 311 and the floating platform 100, thereby increasing the service life thereof.
In some embodiments of the present application, the horizontal section of the floating platform 100 is a quadrilateral structure, the number of the fixed rope portions 311 is four, an angle of 90 degrees is formed between the adjacent fixed rope portions 311 and the connection positions of the floating platform 100, and a line between the adjacent fixed rope portions 311 and the connection positions of the floating platform 100 forms an angle of 45 degrees with the side of the corresponding floating platform 100.
Correspondingly, the number of the auxiliary ropes 400 is four, and each auxiliary rope is arranged on the diagonal line of the floating platform 100, so that the auxiliary ropes 400 and the fixed ropes are staggered, and the stability of the floating platform is improved.
The upper sides of the corner cable sets 500 are connected to the four corners of the floating platform 100, respectively, and the corner cables and the auxiliary cables 400 are connected to the lower side of the floating platform 100 in a catenary connection manner.
To ensure structural strength of the mooring component, the main line 300 is longer and stronger than the auxiliary line 400 and the corner line.
