Description

Background
With the rapid development of social economy, the demand of various countries in the world for energy has increased dramatically since the 20 th century. In order to solve the problem of exhaustion of non-renewable energy resources and the increasing deterioration of the environment, the search for a novel alternative, renewable and clean energy has become a consensus in various countries all over the world. The ocean is taken as a main body occupying 70 percent of the spherical area, so that the ocean not only has abundant resources such as aquatic products, petroleum and the like, but also contains huge energy sources, the ocean energy sources mainly exist in the forms of tides, waves, temperature difference, salinity gradient, ocean current and the like, the utilization of the ocean energy has great potential, and the improvement of the development and research of the ocean energy has great significance. Furthermore, offshore photovoltaics is another important form of offshore energy utilization. Compared with onshore photovoltaics, the offshore photovoltaic has natural environmental advantages, the water surface is wide without shelters, the sunshine is long, the utilization is sufficient, the generated energy can be obviously improved, the offshore photovoltaic generated energy is 5% -10% higher than the onshore photovoltaics, the land occupation is small, and the offshore photovoltaic is easy to combine with other industries. China has abundant offshore photovoltaic resources, and theoretically, the development capacity of offshore photovoltaics is nearly 7 hundred million kilowatts. The development of clean energy such as offshore photovoltaic energy, wave energy and the like becomes an important way for realizing the double-carbon goal in China.
On the other hand, the deep and remote sea has wide water area, excellent water quality and high water body exchange speed. The environment in the deep and far sea aquaculture net cage is stable and is closer to the nature; the natural bait is more, and the bait is less; the shape and the meat quality of the cultured fish are close to those of wild fish. The development of deep open sea cage culture is an important measure for relieving the pressure of offshore culture environment and breaking through the problems of resource limitation and space restriction. How to comprehensively develop and utilize ocean energy, solar energy and ocean fishery resources at low cost is a very important research topic.
At present, devices for generating electricity by using wave energy and solar energy are available in the market, a photovoltaic panel is arranged on the upper surface of a floating platform, and a wave energy generating device is arranged on the side surface of the floating platform. Due to the existence of waves, in order to avoid wave attack on the photovoltaic panels, the photovoltaic panels are generally required to be arranged at the middle part of the floating platform when being arranged, so that the photovoltaic panels are prevented from being damaged by wave attack, the number of the photovoltaic panels is reduced, and the power generation capacity is further reduced. Or increasing the freeboard height of the floating platform, the photovoltaic panels can be arranged at the edge of the floating platform, but the material consumption of the floating platform is increased, resulting in higher cost of the floating platform. On the other hand, offshore high-density polyethylene aquaculture net cages or wooden fish rafts have a plurality of damage accidents under typhoon, so that net-broken fish die, fishermen have heavy losses, and the traditional net cage form is not suitable for the requirement of deep and open sea fishery aquaculture; when the cage culture moves to deep and far sea, the power supply is also a difficult problem because of far offshore.

Detailed Description
The core of the invention is to provide an offshore comprehensive platform, which realizes comprehensive development and utilization of deep and distant sea wave energy, offshore photovoltaic and fishery resources.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 3, an embodiment of the invention discloses an offshore integrated platform, which comprises a floating platform 100, a photovoltaic power generation device 300, a wave power generation device 400 and a aquaculture net cage 500.
The floating platform 100 is an installation foundation for the wave energy power generation device 400, the photovoltaic power generation device 300 and the aquaculture net cage 500. The wave energy power generation device 400 is arranged on the side surface of the floating platform 100, the photovoltaic power generation device 300 is arranged on the upper surface of the floating platform 100, and the aquaculture net cage 500 is suspended at the bottom of the floating platform 100.
The photovoltaic power generation device 300 comprises a photovoltaic panel support upright 302 and a photovoltaic panel 301, wherein the height of the photovoltaic panel support upright 302 can be set according to requirements as long as wave attack to the photovoltaic panel 301 can be avoided. Photovoltaic panel support columns 302 are fixed to the upper surface of floating platform 100, and photovoltaic panels 301 are disposed on top of photovoltaic panel support columns 302 to raise the height of photovoltaic panels 301.
According to the offshore integrated platform provided by the invention, the wave energy power generation device 400 and the photovoltaic power generation device 300 are integrated on the same floating platform 100, so that the wave energy power generation and the photovoltaic power generation not only have periodic complementary effects, but also the power generation capacity is improved, and the practicability and the power generation efficiency are greatly enhanced. Photovoltaic power generation device 300 adds photovoltaic panel support column 302 to photovoltaic panel 301, sets up photovoltaic panel 301 in the top of photovoltaic panel support column 302 to can improve the height of photovoltaic panel 301, the existence of photovoltaic panel support column 302 can make photovoltaic panel 301 exceed the sufficient distance of hydrostatic plane, avoids the wave to slam photovoltaic panel 301, and need not increase the topsides of floating platform 100, and this cost that has reduced floating platform 100.
In one embodiment of the invention, vessel 100 is a rectangular steel vessel. That is, the floating platform 100 is made of steel and has a rectangular parallelepiped shape as a whole, in this embodiment, by using the floating platform 100 in the form of a barge having a large waterplane, the floating platform 100 is stable and can provide a sufficient laying area for the photovoltaic power generation apparatus 300.
As shown in fig. 6, the floating platform 100 includes a floating platform body 101 and heave plates 102. Wherein the heave plate 102 is arranged around the floating platform body 101, in particular, the heave plate 102 can be welded with the floating platform body 101. The existence of heave plate 102 increases the damping and additional mass of floating platform 100, improves the motion performance of floating platform 100, improves the ability of floating platform 100 to resist wind and waves, and then improves the stability of the offshore integrated platform in extreme weather.
Heave plates 102 may be disposed around the circumference of the vessel 101 or may be symmetrically disposed on opposite sides of the vessel 101. For example, on both sides of the long side of the rectangular parallelepiped structural vessel body 101, or on both sides of the short side of the rectangular parallelepiped structural vessel body 101. Heave plates 102 may be disposed around the bottom of the vessel 101 or may be positioned slightly above the bottom of the vessel 101, so long as it is ensured that the heave plates 102 are below water level after the offshore integrated platform is installed on the sea surface.
To improve the structural strength of heave plate 102, vessel 100 may also be provided with stiffeners 103, where stiffeners 103 are connected to the sides of vessel body 101 and heave plate 102, respectively. The reinforcing rib 103 may be in the form of a right triangle, wherein one of the right-angled sides is welded to the side of the floating platform body 101, and the other right-angled side is welded to the heave plate 102. When the heave plate 102 is subjected to the heave, roll and pitch action of waves, the heave plate 102 is prevented from deforming under the action of a large external force and the service life of the heave plate 102 is prevented from being influenced under the action of the reinforcing ribs 103. The reinforcing ribs 103 are plural and arranged at intervals in the extending direction of the heave plate 102.
As shown in fig. 6 and 7, in order to further improve the motion performance of the floating platform 100, in an embodiment of the invention, the floating platform body 101 is provided with a plurality of damping tanks 104 penetrating the upper and lower surfaces. In the embodiment, the damping pool 104 is arranged on the floating platform body 101, so that the seawater entering the damping pool 104 can be shaken in the damping pool 104 under the impact of wind and waves, the wave energy is dissipated, the additional damping of the floating platform body 101 is increased, and the motion performance of the floating platform 100 is improved. The presence of the damping pools 104 may also reduce the amount of steel used for the vessel 100, which in turn reduces the cost of manufacturing the vessel 100.
Specifically, the damping cells 104 may have the same shape or different shapes, for example, each damping cell 104 may have the same shape such as a rectangle, a square, a circle, an ellipse, etc., and each damping cell 104 may also have different shapes, for example, a part of the damping cells 104 is a circle, a part of the damping cells 104 is a rectangle, a part of the damping cells 104 is an ellipse, etc.
The shapes of the damping tanks 104 are the same, the sizes of the damping tanks 104 may be the same or different, the damping tanks 104 may be arranged at different positions of the floating platform body 101 as required, and the sizes of the damping tanks 104 at different positions may be different in order to adapt to corresponding spaces.
The distance between any two adjacent damping cells 104 may be the same or different. The arrangement position of the damping cell 104 cannot affect the arrangement of the photovoltaic power generation apparatus 300.
As shown in fig. 4, in this embodiment, a plurality of damping tanks 104 are arranged at intervals along the length direction of the floating platform body 101, and the damping tanks 104 shown in fig. 6 have a rectangular parallelepiped shape and the same size. In order to arrange more photovoltaic power generation devices 300 on one floating platform 100, the photovoltaic power generation devices 300 are generally arranged in a row, and in this embodiment, the photovoltaic power generation devices 300 are arranged in a row along the length direction of the floating platform body 101, that is, each row of the photovoltaic power generation devices 300 is parallel to the long side of the floating platform body 101.
Each row of photovoltaic power generation devices 300 is arranged at intervals along the width direction of the floating platform body 101, and the photovoltaic panel support columns 302 are arranged on the floating platform body 101 between two adjacent damping tanks 104. The width of the floating platform body 101 between the two damping cells 104 should be such that the photovoltaic panel support columns 302 can be arranged. That is, in the embodiment, the damping pools 104 are disposed in the spaces between the photovoltaic panel support columns 302, so that when a plurality of damping pools 104 are disposed on the floating platform body 101, the arrangement of the photovoltaic power generation devices 300 is not affected, and the number of the photovoltaic power generation devices 300 is not reduced.
As shown in fig. 2 and 4, the wave energy power generation device 400 is arranged on at most three sides of the floating platform 100, and at least one side of the floating platform 100 is reserved with a ship-approaching space for providing an operation and maintenance ship. The scheme shown in fig. 4 is: wave energy power generation devices 400 are arranged on two long side surfaces of the floating platform 100, and ship-approaching spaces are reserved on two short side surfaces of the floating platform 100. Of course, the wave energy power generation device 400 may be arranged on only one long-side of the floating platform 100, and the wave energy power generation devices 400 may also be arranged on two long-side sides and one short-side of the floating platform 100.
By integrating the wave energy power generation device 400 on the floating platform 100, the embodiment of the invention can share the power infrastructure and other components with the photovoltaic power generation device 300, thereby reducing the total cost of installation, operation and maintenance. In addition, the wave energy power generation device 400 can also function as a damper, and can effectively reduce the motion response of the floating platform 100. Wave energy power generation devices 400 are not installed at the head and the tail of the floating platform 100 (short side surfaces of the floating platform 100), so that the operation and maintenance ship can conveniently stop.
As shown in fig. 9, in a specific embodiment of the invention, the wave energy power generation device 400 includes a rocker arm 402 and a hydraulic power take-off 403.
Wherein, one end of the rocker arm 402 is hinged to the floating platform 100, the other end is provided with a floater 401 which is used for being placed on the horizontal plane, and the floater 401 and the rocker arm can be welded together. The floating platform 100 may be provided with a first hinge bracket 405, and the swing arm 402 may be hinged to the first hinge bracket 405 through a hinge shaft.
The piston cylinder of the hydraulic power output device 403 is hinged to the floating platform 100, and the piston rod of the hydraulic power output device 403 is hinged between two ends of the rocker arm 402. Specifically, a second hinge support 404 may be provided on floating platform 100, and a piston cylinder of hydraulic power take-off 403 may be hinged to second hinge support 404 through a hinge shaft. A third hinge support 406 is provided at a position between both end points of the swing arm 402, a piston rod of the hydraulic power output apparatus 403 may be hinged to the third hinge support 406 through a hinge shaft, and the third hinge support 406 may be provided at a position around the middle position of the swing arm 402.
When waves exist, the floater 401 rises and falls along with the wave surface, so that the rocker arm 402 is driven to rotate, and the piston rod of the hydraulic power output device 403 is driven to perform piston motion in the piston cylinder of the hydraulic power output device 403. The movement of the piston rod enables the hydraulic power output device 403 to generate hydraulic pressure energy, and then the hydraulic motor drives the generator to generate electricity, so that the conversion from wave energy to electric energy is realized.
As will be understood by those skilled in the art, the closer the third hinged support 406 is located to the float 401, the greater the compression distance of the float 401 on the piston rod along with the fluctuation of the waves, but the smaller the moment arm, the greater the compression resistance; the closer the third hinge support 406 is located to the first hinge support 405, the less the float 401 compresses the piston rod with the wave, but the less compression resistance due to the larger moment arm. One skilled in the art can set the position of the third hinge support 406 on the swing arm 402 as desired.
As shown in fig. 2, 5 and 7, the aquaculture net cage 500 is suspended from the bottom of the floating platform 100. The top opening of the aquaculture net cage 500 is the same as the bottom opening of the damping pool 104, and the aquaculture net cage 500 is arranged right below the damping pool 104.
As shown in fig. 7 and 8, in an embodiment of the present invention, the aquaculture net cage 500 includes a side net 501, a bottom net 502 and a sinker 503.
Each aquaculture net cage 500 comprises 4 side net clothes 501 and 1 bottom net clothes 502, and the side net clothes 501 and the bottom net clothes 502 enclose the aquaculture net cage 500.
In this embodiment, the sinker 503 may be a steel pipe or a high-density polyethylene pipe with a heavy object such as concrete or iron ore. The existence of the sinker 503 can ensure that the culture volume of the culture net cage 500 cannot generate great loss under the action of wave current.
According to the embodiment of the invention, the aquaculture net cage 500, the wave energy power generation device 400 and the photovoltaic power generation device 300 are integrated on the floating platform 100 with a steel structure, so that the comprehensive development and utilization of ocean resources are realized, and the total cost required by the development of single resource is reduced. The floating platform 100 with a steel structure is used as the main structure of the aquaculture net cage 500, so that the safe development of deep and open sea aquaculture is ensured. The electric energy generated by the wave energy power generation device 400 and the photovoltaic power generation device 300 can be supplied to the aquaculture net cage 500 for aquaculture, so that the problem of electric power supply of the aquaculture net cage 500 is solved. In addition, aquaculture cage 500 can also increase the additional mass and additional damping of vessel 100, which can further reduce the motion response of vessel 100.
To prevent floating platform 100 from drifting around in the wind when the storms are high, in this embodiment, floating platform 100 is moored to the seabed by a plurality of mooring lines 200 to improve the stability of floating platform 100.
The offshore comprehensive platform provided by the invention has a reasonable and stable structure, can be used for the construction of large offshore power plants, and can supply power for islands and other offshore marine equipment and the like
