Description
Technical Field
The invention relates to the field of ocean energy development, in particular to a wave energy power generation system in ocean energy development.
Background
Along with the increasing exhaustion of global land fossil energy and the increasing trend of environmental pollution, the effective utilization of clean and renewable ocean energy becomes an important choice for the main coastal national energy strategy in the world. International agency for energy estimates that nearly 50% of the worldwide electricity supply in 2050 will come from renewable sources, in order to then supply CO2Halving emissions and reducing significant irreversible climate change effects. It is estimated that ocean energy can be generated for every 1MWh of electricityTo avoid 300 kg of CO2And (4) generating. Therefore, ocean energy as a renewable energy source with huge reserves can play an important role in the effort to realize global carbon dioxide emission reduction.
The wave energy development and utilization technology research in China begins in the 70 s and 80 s of the 20 th century, and is rapidly developed. However, there is a large gap compared to the international advanced level.

The wave energy power generation device shown in fig. 1 is provided with a power generation device c on a ship side on a ship body a, realizes energy collection by pushing a floater b through waves, and finally generates electric energy. However, the hull structure a of the ship is heavy, difficult to move again after being fixed, poor in flexibility and difficult to follow the flow direction of the wave flow. In addition, when the ship encounters severe weather, the whole ship body swings up and down when being impacted by waves due to the large contact area between the ship body and the water body, so that the stability is poor, and the ship is even in danger of overturning in extreme weather. In addition, since the hull is solid and the power generation device is installed on the ship side, the transmission of waves of seawater is directional, and when the power generation device on the ship side of one surface acts, the power generation device on the surface opposite to the ship side cannot necessarily collect wave energy or the collected wave energy is very little, so that the overall energy collection efficiency is low.
In view of the above, there is a need for a wave energy power generation apparatus that can solve the above problems so as to improve stability and efficiency thereof while not requiring consideration of flexibility.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described with reference to the accompanying drawings.
As shown in fig. 2 to 6, the present invention includes a main platform capable of floating on the water surface and a wave energy power generation device disposed on the main platform. Wherein the upper surface of the main platform can be arranged in a polygon or a circle or a combination of the polygon and the circle, or an irregular shape. As shown in fig. 2, in this embodiment, the main platform adopts a square upper surface, wherein the upper surface of the main platform can be set according to the number of wave energy power generation devices and the length of each side or the maximum diameter of the plane of the upper surface according to the requirements, specifically based on the actual operation requirements.
As shown in fig. 2 and 3, the main platform consists of a truss structure 1. The truss structure 1 is formed by connecting a plurality of sectional materials. Specifically, the section bar is a metal section bar, and the truss structure 1 is formed by welding or connecting a plurality of metal section bars through bolts; or the section bar is a polymer section bar, and the truss structure 1 is formed by welding, bonding or bolt connection of the polymer section bar. The truss structure is made of metal sectional materials, so that the structural stability, rigidity, reliability and safety of the whole main platform are guaranteed. When the metal section is adopted, the metal section can be a metal round pipe, an angle steel, a square tube, an H-shaped steel and the like. More specifically, the metal profile used in this embodiment is a metal pipe. It should be noted that, in order to ensure the service life of the platform and for safety reasons, when metal and other materials which are easily corroded by seawater are used, corrosion prevention treatment is required according to the requirements of maritime workers. When the section bar is a polymer section bar, the section bar with high rigidity and strong corrosion resistance, such as the section bar made of glass fiber reinforced plastic, polyethylene, polyvinyl chloride, engineering plastics and the like, needs to be selected.
As an offshore operation platform, each part of the system, which is positioned above and below the water surface, is not subjected to the impact of seawater and wave current all the time, the process is used for absolutely ensuring that the seawater does not enter the hollow part inside the section bar, the manufacturing cost is high, even if the system is used for completely sealing, the sealing performance of the connecting position of the whole truss structure is difficult to ensure along with the time. For this purpose, the hollow positions inside the profiles constituting the truss structure may be filled with foam material, as desired, e.g. the hollow parts of the metal profiles of the truss structure 1 are filled with foam material either completely or partially. When the truss structure is made of a polymer profile, the hollow part of the polymer profile of the truss structure 1 may be completely or partially filled with a polymer foam material. In addition, in the truss structure integrally formed of the profiles, not all the profiles having the hollow portion need to be filled with the foam, but the profiles need to be filled at corresponding positions, such as an underwater portion and a key portion, which are in contact with seawater, according to actual needs. And one of the purposes of filling the hollow position in the section bar with the foam material is to reduce the hollow volume in the section bar and physically reduce the entry of seawater. And secondly, foam materials are filled in the hollow position in the section bar on the platform, the position for filling the foam can be designed as required, certain buoyancy can be kept after the foam is filled in the section bar, and further the buoyancy parameter design of the whole platform can be carried out, so that the lost buoyancy can be still controlled in the design range even under the condition that seawater enters the hollow position in the section bar, and the safety and the reliability of the truss structure are further kept. The filled foam material can be foam plastics made of high polymer materials such as PE, PP, PS, PVC, EVA, PU and the like or buoyancy materials made of other materials.
A damping device 2 is arranged at the lower part in the main platform. The damping device can be in various forms, such as a damping plate, a damping box and the like, and the damping box can be a solid box body or a non-solid box body. In this embodiment, the damping device is a damping plate. When encountering waves, the damping device can delay or even reduce the wave-following motion of the main platform, and the stability of the main platform is improved. In actual operation, a damping plate is arranged below the main platform, the damping effect of the whole truss structure on waves is increased in wave fluctuation motion, and the wave following motion of the main platform is reduced. Meanwhile, the damping plate also has a counterweight function and can be distributed and arranged at different positions of the main platform according to specific requirements. The damping plate may be a metal plate or a non-metal plate of different geometries. In addition, in order to further increase the stability and reliability of the main platform and improve the wind and wave resistance, a counterweight body can be arranged at the lower part of the truss structure. The weight of the truss structure can be increased due to the arrangement of the counterweight body, the gravity center of the truss structure is reduced, the stability of the whole main platform is improved, and the reliability of the main platform is improved.
In addition, a floating body 3 may be provided on the main platform in order to increase the buoyancy of the entire main platform. The float 3 may be a buoyancy tank, a buoyancy block or a combination of both. According to the stress condition of each position of the main platform, the main platform is generally symmetrically and uniformly distributed on the main platform, so that the buoyancy of the main platform is balanced, and the stability and the reliability of the main platform are ensured. In this embodiment, the floating body is an existing buoyancy tank, buoyancy block, or the like, and the corresponding size is designed mainly according to a specific truss structure. When the truss structure is large, a buoyancy tank with a large size needs to be put in. Similarly, if buoyancy blocks are used, the buoyancy generated and the deployment principle are consistent with those of the buoyancy tanks to avoid the imbalance of the main platform. The buoyancy block is also sized according to the particular truss structure size. For safety reasons, a wave-transparent plate is arranged on the upper surface of the main platform. The wave-transparent plate can provide a reliable operation area for workers, and provides safety guarantee for installation and later maintenance.
The wave energy power generation device comprises a wave energy collecting device and an energy conversion device, wherein the wave energy collecting device collects wave energy and finally converts the wave energy into electric energy through the energy conversion device. Here, the wave energy collecting device may be a cantilevered float device or a central tube float device.
When the wave energy collecting device is a cantilever type floater device, the device comprises a cantilever 5 and a cantilever floater 6, wherein the cantilever 5 is hinged with the main platform through a hinge point 4, the cantilever floater 6 is connected to the outer end of the cantilever 5, and the energy conversion device is connected with the inner end of the cantilever 5 and converts kinetic energy at the inner end of the cantilever 5 into electric energy. Here, the hinge point 4 is arranged on the main platform near the edge, and the cantilever float 6, which may be hinged or fixedly connected to the cantilever 5, is arranged at the end of said cantilever 5 extending out of the main platform, in this embodiment in a hinged state. The cantilever float 6 is connected to the cantilever 5 by a hinge axis 10. The cantilever floats extended out of the main platform are contacted with the surface of seawater, and wave crests and wave troughs of waves circularly reach the cantilever floats along with the movement of the waves, so that the cantilever floats are driven to do reciprocating rotation and up-and-down floating movement along the hinge shaft 10, and the wave energy collection is realized. In addition, the wave energy collecting device is arranged to extend out of the main platform, so that the contact area of the whole main platform and the water surface is further larger, and the stability and the reliability of the main platform are improved; set up outside the main platform for wave energy collection device can be directly to wave, obtains better unrestrained function, and the structure of truss makes to set up in main platform wave energy collection device, and no matter which position homoenergetic obtains the wave energy, has promoted wave energy power generation's efficiency.
The energy conversion device comprises a generator, wave energy collected by the cantilever type floater device is finally converted into electric energy through the generator, and energy conversion is carried out between the cantilever type floater device and the generator through a hydraulic system 11, a gear mechanism or a combination of the gear mechanism and a belt pulley mechanism. In the case of the wave energy collecting device being a cantilevered buoy device, the other end of the boom 5 within the main platform may be connected to a hydraulic system 11 or other mechanical device. According to the lever principle, when the cantilever float encounters the wave crest of a wave, the cantilever float rotates upward around the hinge shaft 10, and the inner end of the cantilever moves downward; when the cantilever float encounters the trough of a wave, the cantilever float moves down and rotates about the hinge axis 10, and the inner end of the cantilever moves up. Under the principle, the hydraulic system or other mechanical devices convert the up-and-down reciprocating rotary motion of the cantilever floater driven by waves into the corresponding up-and-down reciprocating motion of machinery, and then the hydraulic system or other mechanical devices drive the generator to move so as to convert mechanical energy into electric energy and finally realize power generation.
