Description

Technical Field

[0001] The present invention relates to the field of offshore photovoltaic technology, in particular to a wave prevention device for a floating box-type offshore photovoltaic platform and a wind-solar co-generation system. Background Art

[0002] In recent years, China has attached great importance to the development of marine energy, especially in the field of photovoltaics. As the available photovoltaic resources on land in China become increasingly scarce, the application field of the photovoltaic industry has begun to extend to the sea. As an emerging way of marine energy development, offshore photovoltaics are favored due to their rich resources and high efficiency, and have become a new trend in the use of solar energy. China has a long coastline and vast sea areas, and the coastal areas have abundant solar energy resources, making offshore photovoltaics a new way to develop marine energy resources and play a key role in building a new power system. Therefore, offshore photovoltaic power generation technology is developing rapidly.

[0003] In an offshore photovoltaic power generation system, a stable platform structure is the key to ensuring that photovoltaic power generation equipment can generate electricity continuously and stably. A platform structure with stronger wind and wave resistance can reduce the risk of photovoltaic panel failure, improve the operating efficiency of power generation equipment, and thus enhance the overall power generation efficiency of offshore photovoltaic power stations.

[0004] At present, the pre-installed platforms for offshore photovoltaic power generation technology usually adopt floating platforms. Floating platforms usually use welding technology to connect and fix multiple pontoons using stainless steel pipes to form the basis for placing photovoltaic panels. However, since the height of these pontoons is fixed, they cannot automatically adjust their height to adapt to severe sea conditions, causing seawater to rush onto the photovoltaic panels and cause the photovoltaic panels to be eroded by seawater. The corresponding economic costs will also increase significantly, which is contrary to the advantages of offshore photovoltaics with low economic costs and high returns. Although this problem can be solved by increasing the overall height of the floating platform, this will cause the floating platform to be continuously affected by the strong sea breeze, which will cause excessive pressure on the mooring structure and easily reduce the life of the mooring structure.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 4 As shown, the present invention first provides a wave prevention device for a pontoon-type offshore photovoltaic platform, including a tension control mechanism 6 and an inflation and deflation mechanism 9 fixedly arranged on the pontoon-type offshore photovoltaic platform, the tension control mechanism 6 is driven and connected to a mesh fixing bag 7, and the mesh fixing bag 7 is located below the pontoon-type offshore photovoltaic platform, a plurality of inflatable cushions 8 are arranged inside the mesh fixing bag 7, the inflatable cushions 8 are connected to the inflation and deflation mechanism 9, and the draft of the pontoon-type offshore photovoltaic platform can be changed during the inflation and deflation process.

[0022] The present invention is applicable to a floating box type offshore photovoltaic platform, and the distance between the top surface of the floating box type offshore photovoltaic platform and the sea level is changed by changing the draft depth of the floating box type offshore photovoltaic platform to prevent waves from surging onto the floating box type offshore photovoltaic platform. Specifically, when the current is relatively gentle and the waves are small, the inflatable cushion 8 is controlled by the filling and discharging mechanism 9 to be in an unfilled state. At this time, the buoyancy of the floating box type offshore photovoltaic platform is small, the distance between the top surface of the floating box type offshore photovoltaic platform and the sea level is small, the overall windward area is small, and the force generated by the sea breeze blowing on the floating box type offshore photovoltaic platform is smaller, which can improve the stability of the floating box type offshore photovoltaic platform. Under the sea conditions of rapid current and large waves, the filling and discharging mechanism 9 inflates the inflatable cushion 8 to make the inflatable cushion 8 completely full. At this time, the buoyancy of the inflatable cushion 8 increases, and all the inflatable cushions 8 work together to push the floating box type offshore photovoltaic platform to move upward, thereby increasing the distance between the top surface of the floating box type offshore photovoltaic platform and the sea level, preventing waves from surging onto the floating box type offshore photovoltaic platform, and then avoiding seawater erosion of the photovoltaic panel 10. On the other hand, the inflatable cushion 8 can also significantly absorb the impact force brought by the waves, reduce the impact of the waves on the floating box type offshore photovoltaic platform, and thus extend the service life of the floating box type offshore photovoltaic platform, and also help maintain the stability of the entire floating box type offshore photovoltaic platform. In order to ensure the stability of the position of the inflatable cushion 8, avoid the inflatable cushion 8 being displaced by the impact of the waves, resulting in the inability to continue to smoothly support the floating box type offshore photovoltaic platform, the present invention is also provided with a tension control mechanism 6 and a mesh fixing bag 7, through which all the inflatable cushions 8 can be constrained, and the inflatable cushions 8 are always constrained below the floating box type offshore photovoltaic platform to ensure that the floating box type offshore photovoltaic platform can be supported. Further, through the tension control mechanism 6, regardless of the restart state of the inflatable cushion 8, it is ensured that the mesh fixing bag 7 can fit closely with the inflatable cushion 8, thereby ensuring that the inflatable cushion 8 can be constrained. In addition, the mesh fixing bag 7 is a porous structure, and the waves can impact the inflatable cushion 8 and the energy absorbed by the inflatable cushion 8 can be extended. The life of the mesh fixing bag 7 can be extended.

[0023] The present invention can change the height of the pontoon-type offshore photovoltaic platform by changing the inflation state of the inflatable cushion 8, thereby preventing waves from surging onto the pontoon-type offshore photovoltaic platform and eroding the photovoltaic panels 10, and can also prevent the pontoon-type offshore photovoltaic platform from being continuously subjected to excessively strong winds, thereby ensuring the stability and safety of the pontoon-type offshore photovoltaic platform; the present invention can always constrain the inflatable cushion 8 below the pontoon-type offshore photovoltaic platform through the cooperation of the mesh fixing bag 7 of the tension control mechanism 6, thereby ensuring that the height of the pontoon-type offshore photovoltaic platform can be smoothly controlled.

[0024] The specific structure of the tension control mechanism 6 is as follows: the tension control mechanism 6 includes a plurality of electric winches fixedly arranged on the floating box-type offshore photovoltaic platform, and a plurality of electric winches are arranged at the corners of the floating box-type offshore photovoltaic platform, and the electric winch is driven and connected with a hanging cable 11, and the hanging cable 11 extends downward from the side of the floating box-type offshore photovoltaic platform and is fixedly connected to the edge of the mesh fixing bag 7. When it is necessary to change the tightness of the mesh fixing bag 7 to ensure that the mesh fixing bag 7 can fit tightly with the inflatable cushion 8, the electric winch is used to drive the hanging cable 11 to be untied from the wire drum of the electric winch or wound onto the wire drum, and the hanging cable 11 can drive the mesh fixing bag 7 to move upward or downward during the operation process. When the inflatable cushion 8 is deflated from a full state to an unfilled state, the hanging cable 11 drives the mesh fixing bag 7 to move upward, and when the inflatable cushion 8 is restarted from an unfilled state to a full state, the mesh fixing bag 7 moves downward. It should also be noted that the hanging cable 11 extends downward from the side of the floating box type offshore photovoltaic platform and is fixedly connected to the mesh fixing bag 7, and the open end of the mesh fixing bag 7 can be sleeved on the peripheral side of the floating box type offshore photovoltaic platform to ensure that the mesh fixing bag 7 can move upward smoothly. The specific structure and principle of the electric winch belong to the mature existing technology and will not be repeated here.

[0025] The arrangement of the inflatable cushion 8 and the specific structure of the inflation and deflation mechanism 9 are as follows: the multiple inflatable cushions 8 are divided into at least two groups, each group of inflatable cushions 8 has a plurality of inflatable cushions, and the inflation and deflation mechanism 9 includes at least two air compressors fixedly arranged on the floating box type offshore photovoltaic platform, one air compressor is connected to a group of inflatable cushions 8, and different groups of inflatable cushions 8 are connected through a series assembly. Based on this arrangement, one air compressor can control a group of inflatable cushions 8, reduce the time consumption of the inflation and deflation process of the inflatable cushions 8, and thus speed up the speed of changing the floating box type offshore photovoltaic platform. On this basis, by setting up a series assembly, when one of the air compressors fails, the gas delivery pipes of other air compressors can be connected to the inflatable cushion 8 connected to the failed punching machine. Although this will increase the time consumption of the inflation and deflation process, it can ensure that all inflatable cushions 8 can be smoothly inflated and deflated. The series assembly can include two connecting pipes and a valve, the connecting pipe is used to connect the inflatable cushions 8, and the valve is used to control the conduction or cutoff of the two connecting pipes.

[0026] The specific structure of the inflatable cushion 8 is as follows: the inflatable cushion 8 is composed of a plurality of monomers 13 arranged in parallel, and the plurality of monomers 13 are all connected, one of the monomers 13 is connected to the inflation and deflation mechanism 9, the monomer 13 has a downwardly disposed protrusion, and a groove 14 is formed between the protrusions on two adjacent monomers 13. When the waves hit the inflatable cushion 8, a portion of the seawater can pass through the groove 14, and the seawater in the two adjacent grooves 14 generates the same force but opposite direction of squeezing force on the inflatable cushion 8, thereby stabilizing the position of the inflatable cushion 8.

[0027] like Figures 1 to 6 As shown, the present invention further provides a wind-solar co-generation system, comprising a plurality of positioning anchor piles 1 fixed on the seabed, on which wind turbines 2 are fixedly mounted, the plurality of positioning anchor piles 1 enclose an installation area, in which a pontoon-type offshore photovoltaic platform floating on the sea surface is arranged, the pontoon-type offshore photovoltaic platform is connected to the positioning anchor piles 1 by mooring cables 4, and the pontoon-type offshore photovoltaic platform is provided with the above-mentioned device for preventing the pontoon-type offshore photovoltaic platform from coming up against waves and a plurality of photovoltaic panels 10.

[0028] The wind-solar co-generation system of the present invention can realize photovoltaic power generation and wind power generation in the same area on the sea surface at the same time, has higher power generation efficiency, and can output more electric energy. In the system of the present invention, the positioning anchor pile 1 can anchor the floating box type offshore photovoltaic platform, so that the wind turbine 2 and the floating box type offshore photovoltaic platform can be installed and fixed by the positioning anchor pile 1 at the same time, which simplifies the overall structure, reduces the complexity of the construction process, and reduces the construction cost. On the other hand, the floating box type offshore photovoltaic platform can absorb the energy of the waves, can protect the positioning anchor pile 1, and extend the service life of the positioning anchor pile 1.

[0029] The specific structure of the floating box offshore photovoltaic platform is as follows: the floating box offshore photovoltaic platform includes a plurality of floating units 5 floating on the sea surface, all floating units 5 are evenly divided into multiple groups, each group of floating units 5 has a plurality of floating units 5, and the plurality of floating units 5 in the same group are distributed in a matrix, and a group of floating units 5 supports a photovoltaic panel 10. The floating unit 5 can adopt a conventional floating box structure in the art, which will not be described here. Adjacent floating units 5 can be welded and fixed to form a whole, and each floating unit 5 not only provides a stable installation foundation for the photovoltaic panel 10, but also ensures the overall structural stability and uniformity of load distribution.

[0030] Furthermore, the positioning anchor pile 1 and the floating box type offshore photovoltaic platform are connected through a mooring assembly 3, and the specific structure of the mooring assembly 3 is as follows: a plurality of first lifting ears 12 are fixedly connected to the edge of the floating box type offshore photovoltaic platform, a plurality of horizontally extending mounting rods 18 are fixedly connected to the positioning anchor pile 1, a plurality of fixed barrels 19 are fixedly connected to the mounting rods 18, the lower part of the fixed barrel 19 is inserted into the seabed, at least one second lifting ear 20 is fixedly arranged on the fixed barrel 19, and the two ends of the mooring cable 4 are respectively connected to the first lifting ear 12 and the second lifting ear 20. The first lifting ear 12, the second lifting ear 20 and the mooring cable 4 together constitute the mooring assembly 3. The use of multiple fixed barrels 19 to connect the mooring cable 4 can avoid excessive local force on the positioning anchor pile 1, extend the service life of the mooring assembly 3, and ensure the stability of the mooring.

[0031] In order to further improve the stability of the fixed barrel 19, two parallel fixed rings 15 are fixedly mounted on the positioning anchor pile 1, and the mounting rod 18 is located between the two fixed rings 15. The two fixed rings 15 can limit and protect the mounting rod 18 to prevent the mounting rod 18 from being deformed by the impact of waves for a long time. Furthermore, the fixed ring 15 is connected with a reinforcing cable 16, which extends to the side of the fixed ring 15 and is connected to the positioning anchor pile 1. The reinforcing cable 16 can improve the stability of the fixed ring 15.

[0032] In order to further improve the stability of the mounting rods 18 and extend the life of the mounting rods 18, a plurality of fixing rods 17 evenly distributed along the circumferential direction of the positioning anchor pile 1 are fixedly connected between the two mounting rods 18, and through holes are opened on the fixing rods 17, through which the mounting rods 18 pass. The fixing rods 17 can also reinforce the mounting rods 18, thereby achieving further protection for the mounting rods 18.
