Description

Technical Field

[0001] The utility model relates to a modular integrated power generation floating platform, belonging to the technical field of power generation equipment. Background Art

[0002] At present, in order to generate electricity by using ocean energy, many technologies have been put into research. However, in practice, it is found that it is very difficult to achieve industrial application. The main reason is that the sea conditions are complex and there are many unexpected problems. Moreover, there are flow velocity limitations in ocean power generation, so it is divided into wave energy and tidal current energy. Wave energy is more suitable for occasions where the flow velocity is low and ocean current energy cannot be utilized. However, the problems encountered in the prior art mainly focus on that the installation frame is difficult to be used normally in the ocean, and moreover, due to the size limitation of the power generation equipment, the power generation amount cannot be increased.

[0003] To solve this problem, for example, a near-shore V-shaped ocean current power generation field device disclosed in Patent Application No. 201710786200.8 has a plurality of single-body frames arranged in a V-shaped layout; each single-body frame on the two sides of the V shape can place a power generation device, and at least one stabilizing column extending downward from the single-body frame is arranged on each side of the V shape; at least one mud-inserting leg extending downward is arranged on the bottom surface of each single-body frame, each single-body frame has a rectangular structure with the bottom end below the liquid level and the top end above the water surface, and each single-body frame is horizontally fixed and a sinking prevention plate in a horizontal state is arranged at the position where the mud-inserting leg is provided on the bottom surface. It can be seen that in this technical solution, the combination of the designed stabilizing column, mud-inserting leg and sinking prevention plate solves the problem of the installation frame, and at the same time, multiple power generation devices can be installed. However, in practice, it can be found that the construction of the stabilizing column is relatively complex, and it will gradually hollow out the surrounding fixtures during the reciprocating process of seawater. At this time, the weight of the frame will cause it to tilt, and then the entire frame will start to tilt, affecting the balance of the internal power generation equipment and causing damage. Moreover, the repair of the damage is very difficult, and the repair cost even exceeds the manufacturing cost, so it cannot be applied substantially.

[0004] Moreover, from the existing offshore power generation equipment, either it is offshore wind power generation with large investment and slow returns, or it is photovoltaic power generation on an offshore floating platform, which is restricted by the daily sunshine time and affected by offshore climate changes, resulting in a still large actual investment and slow returns.

[0005] As disclosed in a marine floating energy island device with the application number CN202110298681.4, it consists of a main platform 1 of a marine energy island and several modular power generation and energy storage platforms 2; the main platform 1 is a large marine floating platform, on which an integrated power generation system 10, an electric energy storage system 11, an electric energy conversion system 12, an electric energy transmission system 13, an intelligent control system 14 of the energy island, a seawater desalination system 15, etc. are provided; the modular power generation and energy storage platform 2 is a combined modular floating body platform, on which a marine photovoltaic power generation system 21, a marine wind power generation system 22, a marine wave energy power generation system 23, a distributed electric energy storage device 24, a distributed energy conversion and energy storage device 25, etc. are respectively or jointly provided.

[0006] However, it can be seen from its specification that in the structure of its modular power generation and energy storage platform 2, the wind energy is located at the top of the vertical pole, the solar panels are installed obliquely on the frame, and there is no description on how to install the wave energy power generation. Its structure is in an imaginative stage. The applicant found in a large number of experiments that the water turbines of ocean current power generation are mostly unable to operate normally due to entanglement with debris in the ocean, and the maintenance cost is too high to be put into use in practice. There is no good solution to such technical problems in the prior art.

[0007] From the retrieval of the above patent documents and the prior art, no technical solution that can well combine the power generation revenue and the investment return rate and is convenient for installation, maintenance and repair has been disclosed. Utility Model Content

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Embodiment

[0027] As Figure 1 、 2The modular integrated power generation floating platform shown is divided into upper and lower layers. Here, the upper and lower layers refer to: the layer above the water surface is the water - upper framework 1, and the layer near and below the water surface is the water - middle framework 2. This is to ensure that the tidal energy power generation device can generate electricity in the water. Of course, it can also be a wave energy power generation device, such as the wave energy power generation device given in Patent CN202111518854.5. Substantially, the top surface of the water - middle framework 2 is also the bottom surface of the water - upper framework 1 above the water surface.

[0028] The framework is composed of basic cells, and each basic cell is a cubic body 3. For example, in this embodiment, the size of the hexahedron framework is 36 m * 36 m * 24m, which is composed of 18 cubic bodies. The size of each cubic body is 12 m * 12 m * 12m. The framework rods can be made of materials such as steel pipes and plastic pipes, which are hollow inside and closed at both ends to form buoyancy cylinders, or foamed polyethylene materials can be filled in them to form buoyancy cylinders. Or the framework rods can be made of H - steel, angle steel, etc., and are connected by joint seats. In this way, modular components can be processed in a factory on the shore and directly assembled by the sea.

[0029] Each cubic body has 12 framework rods 4. Two adjacent cubic bodies 3 have a coplanar surface, that is, the four coplanar framework rods 4 are shared, thus forming a grid module. The grid module includes the grid module of the water - middle framework 2 and the grid module of the water - upper framework 1. The grid module of the water - middle framework 2 needs to be based on the formation of buoyancy cylinders. The framework rods 4 are bolt - connected through joint seats. After all the fittings are connected, a hexahedron framework is formed, which is convenient for assembly and transportation. An anticorrosion layer is set on the connected framework. The framework in the water is directly made of buoyancy cylinders, so that the entire hexahedron framework floats in the seawater to form a floating platform.

[0030] The buoyancy cylinders and their floating structures of the cubic bodies 3 in the water can be manufactured with reference to those disclosed in CN202110217582.9.

[0031] The part of the floating platform in the water is used to install the tidal energy power generation device 5 or the wave energy power generation device. Due to flow velocity limitations, in some areas where tidal energy cannot be collected for power generation, the wave energy power generation device is used. The tidal energy power generation device 5 is located in the cubic body of the water - middle framework. The wave energy power generation device is installed on the top surface of the water - middle framework, and the energy - taking part of the device is pushed by waves. An overhaul device 6 is set above the cubic body corresponding to the tidal energy power generation device or the wave energy power generation device. The overhaul device 6 is a manual hoist or an electric hoist. A lifting ring is set on the top of the device framework of the tidal energy power generation device for connecting the manual hoist or the electric hoist. This is especially used to solve the overhaul problem of the tidal energy power generation device during on - site work.

[0032] A vertical wind power generation device 7 is arranged at a position in the grid of the waterborne framework body that is not in the same grid as the tidal current power generation device or the wave power generation device, for collecting offshore wind power for power generation. A photovoltaic panel 8 is arranged on the top of the waterborne framework body for collecting solar energy for power generation. The photovoltaic power generation and the vertical wind power generation equipment can both adopt the equipment in the existing technology. We only need to purchase them and directly install them on this platform. The key here is that we have built a platform that cannot be blown down by typhoons of any level, and provided the largest installation space for photovoltaic power generation. Moreover, a wind channel is formed by the space between the photovoltaic panel and the sea level, concentrating the wind for the vertical wind turbine installed therein. Moreover, the vertical wind turbine can generate electricity without too strong wind.

[0033] Four anchors 9 are arranged on the hexahedron framework and are respectively connected to the four corners of the hexahedron framework through anchor ropes. The four anchors arrange the entire platform in the direction of the ocean current, ensuring that the platform is fixed in the position in the seawater and ensuring the operation of the water current power generation equipment. Naturally, the platform will not drift away with the seawater.

[0034] Three 100KW water current generators are installed in the waterborne framework body of the platform. Since a maintenance device is arranged at the corresponding position on the platform, the water current power generation equipment can be hoisted out of the water for maintenance in time, solving the problem of the high cost of borrowing a floating crane ship for the existing water current power generation equipment, and enabling timely, rapid repair and maintenance. Three 20KW vertical wind turbines are installed in the grid of the waterborne framework body, and photovoltaic power generation is arranged on the top surface of the platform. There is a gap between each row, and the photovoltaic area is about 1200m 2 . The superposition of ocean current, wind, and light on this platform eliminates the problem of low conversion rate in the three separate applications, and can achieve a high conversion superposition efficiency of more than 70%. After deducting the conversion coefficients of wind and light and the actual operation days, this embodiment can form a power generation capacity of 2.3 million degrees per year, recover the investment cost in about 3 years, and generate considerable long-term benefits for more than a decade thereafter. Embodiment

[0035] As a modular integrated power generation floating platform design different from Embodiment 1, floating cylinders can be added to the framework rods of the underwater framework body. The grids 3 of the waterborne framework body and the underwater framework body can be modularly manufactured with the same material, and then the buoyancy is calculated according to the installation position in the water, and floating cylinders are added to the underwater framework body. The floating cylinders shall not affect the water current power generation equipment to obtain water energy. For example, the floating cylinders are arranged on the surface of the underwater framework body parallel to the water current direction, so that the entire hexahedron framework floats in the seawater to form a floating platform. In addition to being arranged at the four corners, the anchors can also be arranged at the middle positions on both sides in the direction parallel to the water current to increase the position control of the platform.

[0036] Adjustable counterweights are provided at the four corners formed by the sides of the hexahedron frame to adjust the levelness of the hexahedron frame. Adjustable buoyancy cylinders can also be provided on the surface of the underwater frame body parallel to the water flow direction to adjust the levelness of the platform.

[0037] Taking the 18 grids in Embodiment 1 as an example, on the waterborne frame body, panels are provided on all the surfaces of the grid body located at the center to form a central control chamber, and a chamber door or / and chamber window is provided on one of the side panels. This chamber can be used as a control chamber, a maintenance chamber, a spare parts chamber, an electrical cabinet chamber, etc. Monitoring cameras can also be provided on the waterborne frame body to monitor the working conditions of the wind turbines and water current power generation equipment, facilitating timely maintenance and repair on the platform.

[0038] Of course, the volume of the hexahedron can be continuously expanded according to needs, and only corresponding grid bodies need to be added.

[0039] The above embodiments are only explanations and illustrations of the technical solutions of the present invention and cannot be used to limit the protection scope of the technical solutions of the present invention. All simple deformations based on this solution are within the protection scope of the present invention.
