technical field

The utility model belongs to the field of novel renewable energy technology and marine equipment, in particular to a floating wave energy-wind energy comprehensive utilization platform. the

Background technique

70% of the earth's surface is covered by seawater, which contains huge wave energy. As a renewable energy source, wave energy has great development potential. As the significance of the ocean to human society is becoming more and more important, the research and development of artificial systems in water is also becoming more and more important to national security, economic interests, and scientific research. The use of marine renewable energy is also becoming more and more popular among researchers their attention. Compared with wave energy, my country's wind energy resources are more abundant and widely distributed, and wind energy generation technology is more mature. In recent years, offshore wind energy has developed rapidly due to the characteristics of abundant resources, stable wind speed, and less negative impact on the environment. However, my country's offshore wind power development is still limited to the intertidal zone and shallow sea areas. The foundations of wind turbines adopt gravity foundations and pile foundations, and there are few studies on deep sea areas where wind resources are more abundant. According to the statistical analysis of the National Energy Administration of the United States, wind energy resources in deep waters have great development potential and value, and its development and utilization technology will be an important direction in the future development of wind power technology in the world. To sum up, my country's wave energy and offshore wind energy resources are very rich, and it is imperative to develop comprehensive utilization technologies for wave energy and offshore wind energy. The research on wave energy-wind energy comprehensive utilization technology has considerable industrial prospects, and it is also of great strategic significance to the overall strategic layout of my country's energy conservation and emission reduction. the

At present, the comprehensive utilization technology of offshore wave energy and wind energy is still in the exploratory stage, and relatively mature design schemes are rarely seen. One of them is WindFloat, a three-floating body floating wind turbine based on offshore oil and gas field platform technology. An oscillating water column power generation design is added to its floating body or an oscillating float type point-absorbing wave energy device is added to its middle position. The other is a wave energy-wind energy comprehensive utilization technology based on a barge-type floating platform proposed by ITI Energy of the United States: an air chamber for an oscillating water column power generation device is designed in the middle of the cuboid floating platform. The Norwegian University of Science and Technology also proposed a wave energy-wind energy comprehensive utilization concept STC (Spar-Torus Combination) that combines the mast Spar) type offshore fan Hywind and the oscillating buoy type wave energy device WaveBob. However, in terms of wave energy utilization, these technologies mainly capture the kinetic energy or potential energy of wave energy in the vertical direction. At the same time, considering the stability and safety of the device, it is necessary to ensure that the energy conversion device can adapt to different weather conditions and have the ability to survive under extreme weather conditions. the

The technical problem to be solved by the utility model is: to overcome the deficiencies in the prior art above, to provide a floating wave energy-wind energy comprehensive utilization platform, which uses the floating platform to provide installation foundations for wave energy devices and wind energy devices, and can be utilized The kinetic energy in the horizontal direction of the wave water body provides a stable platform for offshore wind turbines, which is suitable for deep water areas, has high reliability, and is easy to install and move. the

The technical scheme that the utility model solves its technical problem adopts is:

A floating wave energy-wind energy comprehensive utilization platform comprises a floating foundation, a wind turbine, a pendulum plate, a damping plate, an anchor chain, a guide rail, a rotating shaft and a generator. Its characteristics are: the main body of the floating foundation is fixed on the seabed through the tension leg anchor chain connecting the grab force anchor; the front swing plate and the rear swing plate are symmetrically installed on the floating foundation and face the incoming wave direction; the wind turbine and the tower Installed at the center of the floating platform; the swing plate shaft is connected to the generator; the wind turbine is installed on the tower. the

The floating wave energy-wind energy comprehensive utilization platform is characterized in that: the distance between the front swing plate and the rear swing plate is half of the characteristic wavelength of the deployment sea area. the

The above-mentioned floating wave energy-wind energy comprehensive utilization platform is characterized in that damping plates are installed symmetrically along the incoming wave direction under the floating foundation. the

The above-mentioned floating wave energy-wind energy comprehensive utilization platform is characterized in that: the floating foundation is equipped with symmetrical vertical and inclined tension leg anchor chain fixing devices along the incoming wave direction. the

The above-mentioned floating wave energy-wind energy comprehensive utilization platform is characterized in that two guide rails are installed on the floating foundation to connect with the front and rear swing plates. the

The floating wave energy-wind energy comprehensive utilization platform is characterized in that: the pendulum plate is connected to the generator through the rotating shaft, and the generator is fixed on the rotating shaft. . the

When the waves pass through the floating platform, the front and rear swing plates rotate with a single degree of freedom around the rotating shaft under the action of the wave force, driving the generator connected to the rotating shaft to work. At the same time, since the distance between the front and rear swing plates is half of the characteristic wavelength, the wave force on the front and rear swing plates is exactly opposite, and the movement direction and acceleration direction of the front and rear swing plates are also just opposite, which helps Minimize the influence of the pendulum plate under the action of waves on the stability of the floating platform. In particular, two parallel guide rails are set on the floating platform. The pendulum plate, rotating shaft and generator can move along the guide rails and be fixed with bolts. This design helps to adjust the front and rear pendulums according to different regions and sea conditions. The spacing of the plates satisfies the requirement that the distance be half of the characteristic wavelength. the

A symmetrical damping plate is installed under the floating platform along the incoming wave direction, which can promote the climbing and deformation of the wave when the wave interacts with the platform, thereby increasing the wave force and increasing the output of wave energy generation. At the same time, it can form an effective additional damping effect in the horizontal direction and enhance the stability of the floating platform in the horizontal direction. Similarly, symmetrical vertical and inclined tension leg anchor chains are installed below the floating platform along the incoming wave direction to fix the overall floating platform. Among them, the vertical tension legs mainly provide the pulling force in the vertical direction to limit the up and down movement (heave) of the floating platform; the inclined tension legs provide the pulling force in the horizontal and vertical directions and mainly limit the forward and backward movement (surge) and rotation of the floating platform ( pitch). the

The beneficial effects of the utility model are:

As shown in Figure 2, the swing plates 6 and 3 are connected to the generator 11 through the rotating shaft 9; two parallel guide rails 10 are arranged on the floating foundation 4, and the rotating shaft 9 can move along the guide rails 10 and be fixed by bolts; the tower Frame 2 is installed in the middle of two parallel guide rails. . the

The working principle of this embodiment:

In actual use, the floating foundation 4 is in a floating state, and the upper surfaces of the front swing plate 6 and the rear swing plate 3 are close to the horizontal plane. Adjust the distance between the front swing plate 6 and the rear swing plate 3 to half a wavelength according to the characteristic wavelength of the deployment sea area, so that the swing plate is symmetrically placed on the floating foundation 4 and fixed on the guide rail 10 with bolts. Under the action of waves, the pendulum plates 6 and 3 rotate around the rotating shaft 9 and drive the generator to work, and the power generated by it can be integrated with the power output of the wind turbine under the action of wind force to supply power to or store offshore facilities. At the same time, when the crest passes through the front wobble plate 6, the trough is located at the position of the rear wobble plate 3; when the wave trough passes through the front wobble plate 6, the wave crest is located at the position of the rear wobble plate 3, and the motion parameters of the front wobble plate and the rear wobble plate are just opposite , which helps to minimize the sum of the wave forces on the front and rear swing plates, further improving the stability of the floating platform. the

When the wave is transmitted to the floating foundation 4, the damping plate 7 promotes the climbing of the water body, which strengthens the wave force on the floating foundation and improves the wave energy conversion output. At the same time, the damping plates 7 distributed symmetrically front and back and the floating foundation 4 together form a semi-enclosed water body below the floating platform, which increases the additional mass of the overall device and improves the stability of the system in the horizontal direction. During the action of wind, waves, floating platforms, wave energy devices and wind turbines, the vertical anchor chain 8 and the inclined anchor chain 5 provide vertical and lateral pulling forces, which are useful for reducing the heaving, surge and The range of motion in degrees of freedom such as pitch is of great significance. the

Example 2:

Please refer to Fig. 1 and Fig. 3, the only difference from Embodiment 1 is that the damping plate 7 is arranged obliquely, the inclined anchor chain 5 is connected with the damping plate 7, and the vertical anchor chain 8 is directly connected with the floating foundation 4, so that the damping plate 7 has a more obvious promotion effect on wave climbing. the
