Description

Technical Field

[0001] The invention relates to the technical field of wave energy power generation, in particular to a slide rail vibrating float type wave energy power generation platform. Background Art

[0002] my country's vast ocean territory not only contains wave energy, but also contains rich fossil energy under the seabed, such as oil and natural gas. Wave energy devices are currently in the stage of increasingly complete functions and sea trials of engineering prototypes, but the urgent problem facing the wave energy device industry that is about to go commercial is to improve the environmental applicability and service life of wave energy devices. In actual sea conditions, we often face extreme typhoon sea conditions. The impact of typhoon extreme sea conditions on the wave-absorbing float and damage to the device causes damage to the structure of the device. Therefore, traditional wave energy devices usually use the wave-absorbing float to dive or float to avoid the huge wave impact on the free surface. This method has a slow response speed and is difficult to operate. Due to the influence of high salt, high temperature and high humidity near the sea surface, the key components of the wave energy device, especially the energy conversion components, are easily corroded, resulting in a decrease in life. The traditional method is to use high-performance marine engineering materials and equipment, which leads to increased costs. Summary of the invention

[0003] The technical problem to be solved by the present invention is: how to solve the problems that wave energy devices are high in cost, easy to corrode, and difficult to survive in extreme sea conditions such as typhoons.

[0004] In order to solve the above technical problems, the present invention provides a sliding rail vibrating buoy type wave energy power generation platform, comprising:

[0005] A semi-submersible floating platform underwater damping plate, wherein the semi-submersible floating platform underwater damping plate is provided with at least one set of guide components;

[0015] Further preferably, the acute angle formed by the slide rail and the underwater damping plate of the semi-submersible floating platform is β, wherein the acute angle β satisfies: 70°≤β≤80°.

[0016] Further preferably, both ends of the underwater damping plate of the semi-submersible floating platform and the surface buoyancy plate of the semi-submersible floating platform are arranged in an arc shape.

[0021] Compared with the prior art, the slide rail vibrating float type wave energy power generation platform provided by the present invention has the following beneficial effects:

When driven by waves, the wave-absorbing float can slide up and down along the guide assembly, drive the double-rod hydraulic cylinder to move, and capture wave energy through the PTO hydraulic energy conversion device.

[0046] like Figure 1-Figure 4 As shown, this embodiment provides a sliding rail vibration float type wave energy power generation platform, including a semi-submersible floating platform underwater damping plate 10, an above-water platform 30, a semi-submersible floating platform surface buoyancy plate 40, a wave-absorbing float 60, a double-rod hydraulic cylinder 70 and a PTO hydraulic energy conversion device 80; wherein, the semi-submersible floating platform underwater damping plate 10 is provided with at least one set of guide components; the above-water platform 30 is installed on the top of the guide component; the semi-submersible floating platform surface buoyancy plate 40 is fixedly connected to the guide component; the wave-absorbing float 60 is slidably connected to the guide component; the double-rod hydraulic cylinder 70 is installed on the above-water platform 30, and one output end of the double-rod hydraulic cylinder 70 is connected to the wave-absorbing float 60; the PTO hydraulic energy conversion device 80 is installed on the above-water platform 30, and the oil circuit system of the double-rod hydraulic cylinder 70 is connected to the PTO hydraulic energy conversion device 80.

[0047] It should be noted that PTO (Power Take Off) refers to a power output device, whose main function is to transmit the power of the power source to other working devices, such as converting the wave energy of the power source into mechanical power suitable for the working device to achieve specific functions or operations. In the hydraulic system, PTO achieves precise control of the actuator by controlling the flow and pressure of the hydraulic oil; the PTO hydraulic energy conversion device 80 in this application belongs to conventional technical means, and this embodiment does not describe and illustrate its specific structure.

[0048] In some embodiments, the guide assembly is preferably two groups. Specifically, each group of guide assemblies includes two symmetrically arranged slide rails 20, and the slide rails 20 are provided with slide grooves 21; the slide rail vibration float type wave energy power generation platform also includes a slide rod 50, the slide rod 50 is slidably installed in the slide groove 21, and the wave absorbing float 60 is connected to the slide rod 50. In this way, the wave absorbing float 60 is slidably installed on the slide rail 20, and the wave absorbing float 60 can slide up and down along the slide rail 20 under the drive of waves, and drive the double-rod hydraulic cylinder 70 to move, and capture wave energy through the PTO hydraulic energy conversion device 80, that is, under normal working conditions, the wave energy is converted into hydraulic energy.

[0049] In other embodiments, the slide bar 50 may also be replaced by a roller, which is connected to the wave-absorbing float 60 , and the wave-absorbing float 60 with the roller may slide up and down along the slide rail 20 .

[0050] like Figure 5-Figure 8 As shown, in the case of a typhoon, since the wave-absorbing float 60 will be subjected to a great wave load on the water surface, in order to prevent the impact of waves, the double-rod hydraulic cylinder 70, which is a working component, can be converted into an actuator through the PTO hydraulic energy conversion device 80, thereby driving the wave-absorbing float 60 to a certain height, thereby avoiding the impact of waves under the typhoon; in addition, in the present invention, because the water platform 30 is higher than the liquid level, the double-rod hydraulic cylinder 70 and the PTO hydraulic energy conversion device 80 are both placed above the water surface, which can prevent corrosion due to contact with seawater, thereby protecting the main core components, reducing the cost, and effectively extending the service life of the slide rail vibration float type wave energy power generation platform. In addition, it can also reduce the wave force received by the wave-absorbing float 60, reduce the stress on the anchoring system, and ensure anchoring safety.

[0051] In some embodiments, the above-water platform 30, the semi-submersible floating platform surface buoyancy plate 40 and the semi-submersible floating platform underwater damping plate 10 are arranged parallel to each other. When used under normal working conditions, the semi-submersible floating platform underwater damping plate 10 is placed below the liquid surface, the above-water platform 30 is placed above the liquid surface, and the semi-submersible floating platform surface buoyancy plate 40 is suspended on the liquid surface.

[0052] It should be noted that the function of the underwater damping plate 10 of the semi-submersible floating platform is to increase the additional mass and radiation damping characteristics of the platform, thereby maintaining the stability of the platform.

[0053] In some embodiments, the buoyancy plate 40 on the surface of the semi-submerged floating platform has a larger waterline area, which can improve the anti-overturning capability of the platform.

[0054] In some embodiments, both ends of the semi-submersible floating platform underwater damping plate 10 and the semi-submersible floating platform surface buoyancy plate 40 are arranged in an arc shape; thereby, the platform can be ensured to have less resistance in wet towing conditions, which is convenient for towing.

[0055] In some embodiments, the acute angle formed by the slide rail 20 and the underwater damping plate 10 of the semi-submersible floating platform is β, wherein the acute angle β satisfies: 70°≤β≤80°; thereby, the two symmetrically arranged slide rails 20 in each group of guide assemblies are conically designed to facilitate the sliding of the wave-absorbing float 60 on the slide rail 20.

[0056] In some embodiments, the acute angle β is preferably 73°.

[0057] In some embodiments, the double-rod hydraulic cylinder 70 includes a cylinder body 71, a piston rod 72 and a support rod 73. The piston rod 72 is connected to the cylinder body 71, one end of the piston rod 72 is connected to the wave-absorbing float 60, one end of the support rod 73 is connected to the water platform 30, and the other end is connected to the cylinder body 71; wherein, the use of the double-rod hydraulic cylinder 70 can provide equal thrust and movement speed in two directions, can be suitable for the load matching design when the wave-absorbing float 60 does work in both directions, and can geometrically adapt to longer wave-absorbing float movement displacement.

[0058] In some embodiments, the acute angle formed by the axial direction of the piston rod 72 and the upper surface of the semi-submerged floating platform surface buoyancy plate 40 is θ, wherein the acute angle θ satisfies: 60°≤θ≤70°; to ensure that the piston rod 72 moves on the cylinder body 71.

[0059] In some embodiments, the acute angle θ is preferably 66°.

[0060] In some embodiments, the upper surface of the wave-absorbing float 60 is arranged parallel to the surface buoyancy plate 40 of the semi-submerged floating platform, and one end of the piston rod 72 is connected to the upper surface of the wave-absorbing float 60 to ensure that the wave-absorbing float 60 always slides up and down along the slide rail 20.

[0061] In some embodiments, the width of the wave-absorbing float 60 gradually decreases from top to bottom, and the side of the wave-absorbing float 60 facing away from the slide bar 50 is arranged in a curved surface, so that the wave-absorbing float 60 can absorb wave energy to the maximum extent to improve the energy conversion rate.

[0062] In summary, the present invention provides a sliding rail vibrating float type wave energy power generation platform, which slides and installs the wave absorbing float 60 on the guide assembly. Driven by waves, the wave absorbing float 60 can slide up and down along the guide assembly, and drive the double-rod hydraulic cylinder 70 to move, and capture wave energy through the PTO hydraulic energy conversion device 80. In the case of a typhoon, since the wave absorbing float 60 will be subjected to a huge wave load on the water surface, in order to prevent the impact of waves, the double-rod hydraulic cylinder 70, which is a working element, can be converted into an actuator through the PTO hydraulic energy conversion device 80, thereby driving the wave absorbing float 60 to a certain height, thereby avoiding the impact of waves under the typhoon; in addition, in the present invention, because the water platform 30 is higher than the liquid level, the double-rod hydraulic cylinder 70 and the PTO hydraulic energy conversion device 80 are both placed above the water surface, which can prevent corrosion due to contact with seawater, thereby protecting the main core components, reducing the cost, and effectively extending the service life of the sliding rail vibrating float type wave energy power generation platform.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be regarded as the protection scope of the present invention. The basic principles, main features and advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above preferred embodiments. The embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention.

[0064] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
