In addition, the invention also discloses an offshore wind turbine assembly with the wind turbine photovoltaic composite foundation platform.
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.
In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
As shown in fig. 1-3, the invention discloses a floating wind and light composite foundation platform, which comprises a buoyancy column 1 and a photovoltaic panel 2, wherein the buoyancy column 1 is a platform main body, can float on the sea surface and serves as an installation foundation. Specifically, for example, the floating offshore wind turbine main body may be installed on the buoyancy column 1, and in addition, the photovoltaic panel 2 is also installed on the buoyancy column 1, that is, in the present application, by additionally installing the photovoltaic panel 2 on the buoyancy column 1, the wind turbine main body and the photovoltaic panel 2 on the buoyancy column 1 can respectively absorb wind energy and solar energy, that is, the utilization rate of energy is improved, and more electric energy is generated; in addition, the fan main body and the photovoltaic panel 2 are both arranged on the buoyancy column 1, and the utilization rate of the buoyancy column 1 can be improved, so that the number of basic platforms is reduced, and the production cost is reduced; in conclusion, the photovoltaic panel 2 is additionally arranged on the buoyancy column 1 of the offshore wind turbine, so that the benefit can be effectively improved.
In order to protect the photovoltaic panel 2, therefore, when the photovoltaic panel 2 is installed on the buoyancy column 1, the photovoltaic panel 2 is configured to be able to be turned over with respect to the buoyancy column 1, so that the photovoltaic panel 2 can be buckled and unfolded. When the photovoltaic panel 2 is used, when the photovoltaic panel 2 needs to be protected, the photovoltaic panel 2 is turned over relative to the buoyancy column 1, so that the photovoltaic panel 2 is buckled, and the front side of the photovoltaic panel 2 is protected; when the photovoltaic panel 2 needs to be adjusted to work, the photovoltaic panel 2 is unfolded to absorb solar energy. It should be noted that, in the process of turning the photovoltaic panel 2, the angle of the photovoltaic panel 2 can be changed, so that the solar photovoltaic panel can adapt to illumination in different directions, and the utilization rate of light energy can be effectively improved.
Because add photovoltaic board 2 on buoyancy post 1, can increase by the weight of support piece (including photovoltaic board 2 and fan main part), and then influence the draft of buoyancy post 1. Therefore, in order to avoid the buoyancy column 1 from being submerged into the sea to an excessive length, it is necessary to increase the buoyancy of the buoyancy column 1. In view of the above and in combination with the use of the photovoltaic panel 2, the present application is arranged to be in contact with the sea surface when the photovoltaic panel 2 is deployed, in particular, the photovoltaic panel 2 floats on the sea surface when deployed. The contact area with the sea surface is increased by the photovoltaic panel 2, and the larger the contact area is, the larger the buoyancy is. In addition, the contact area between the buoyancy column 1 and the sea surface is increased, so that the buoyancy column is more stable and is not easy to shake.
As shown in fig. 6 and 7, in the specific embodiment, in order to ensure the stability of the buoyancy column, four photovoltaic panels 2 are arranged along the circumference of the buoyancy column 1 in the present application. It should be noted that, splice after photovoltaic board 2 for buoyancy post 1 lock and be the structure that the outline is conical, the photovoltaic board is the toper, can effectively reduce the effect of ice load to buoyancy post 1, and photovoltaic board 2 at this moment can be regarded as the icicle. Can resist external wind, frost, rain and snow through with 2 locks of photovoltaic board, and draw in back with photovoltaic board 2 and form conical structure, can further keep out extreme weather such as external hail, further guarantee photovoltaic board 2's safety.
In a specific embodiment, as shown in fig. 1, a first end (inner circle in fig. 1) of the photovoltaic panel 2 in the present application is provided as a first hinge point 31 hinged to the buoyant column 1, and a second end of the photovoltaic panel 2 can move closer to or farther away from the buoyant column 1. The photovoltaic plate 2 can rotate within a certain angle range relative to the top end of the buoyancy column 1 through the arrangement, namely the included angle between the photovoltaic plate 2 and the buoyancy column 1 is adjusted, and illumination in different directions can be adapted in the overturning process. Specifically, the photovoltaic panel 2 may be hinged in any manner, for example, a hinge may be used, one side of the hinge is fixedly connected to the photovoltaic panel 2 by a thread or a flange, and the other side of the hinge is fixedly connected to the buoyancy column 1. During rotation, the photovoltaic panel 2 rotates relative to the buoyancy column 1 through rotation of the hinge shaft of the hinge.
Preferably, the included angle range between the photovoltaic panel 2 and the floating column 1 can be set according to different requirements, and can be rotated within the range of 60 degrees to 150 degrees, for example. The rotation of the solar energy collecting device can realize the illumination opposite to different angles, and the solar energy absorption rate is improved. In addition, the included angle between the photovoltaic panel 2 and the buoyancy column 1 can be in the range of 0-120 degrees, so that the photovoltaic panel 2 can be buckled and unfolded relative to the buoyancy column 1, and the buckling and unfolding of the photovoltaic panel 2 are completed. In combination with the above two ranges, the angle range between the photovoltaic panel 2 and the buoyant column 1 can also be set larger to have the above two functions. But it is essential that: in the maximum angle range of photovoltaic board 2 pivoted, need guarantee to transfer photovoltaic board 2 the time, can not lead to photovoltaic board 2 to get into the aquatic because of the accident.
In practice, in order to make the photovoltaic panel 2 form a conical shape after being fastened, the photovoltaic panel 2 itself is required to be an arc-shaped member which is bent, specifically, the bent portion extends along the width direction of the photovoltaic panel 2, referring to the middle transverse line shown in fig. 5.
It should be noted that, in the present application, the photovoltaic panel 2 may also be configured as a flat plate structure capable of being fastened and unfolded, and when fastened, the photovoltaic panel 2 may be completely attached to the buoyant column 1, and may also resist extreme weather. In particular, the structure can be arranged in a connection mode similar to the folding and unfolding of an umbrella, and the mode is also in a protection range.
The rotation range of the hinge between the photovoltaic panel 2 and the buoyancy column 1 is limited, the control and the limit of the rotation angle of the hinge can be driven by a driving piece, and the driving piece can be a cylinder or a motor. Specifically, when being the cylinder, can fix the cylinder block on buoyancy post 1 to with the telescopic link articulated with photovoltaic board 2, realize the regulation to photovoltaic board 2 angles through the flexible process of telescopic link. When the motor is a bidirectional motor and is fixed on the buoyancy column 1, the output rotating shaft drives the hinge to rotate, and the hinge is fixed by stopping the rotation of the output shaft through power failure.
Referring to fig. 1, the driving member of the photovoltaic panel 2 may also be a winch 6, and the photovoltaic panel 2 and the winch 6 are connected by a connecting rope 4, specifically, the winch 6 is installed on an installation platform 5 inside the buoyancy column 1, and the connecting rope is reversed and connected by a through hole 8 and a fixed pulley 7 on the surface of the buoyancy column 1.
With reference to fig. 2, fig. 4, fig. 5, and fig. 6, in the present application, the photovoltaic panel 2 may be further configured to be a foldable structure, specifically, the foldable structure includes an installation section 22 connected to the floating column 1 and a free section 21 hinged to the installation section 22, where the hinged position of the free section 21 and the installation section 22 forms a second hinge point 32, the free section 21 is connected to the floating column 1 through a connection rope 4, and the floating column 1 is provided with a winch 6 for winding and unwinding the connection rope 4 to complete buckling and unfolding of the photovoltaic panel 2. When the photovoltaic panel 2 is opened, the contact area with the sea surface can be further increased, and further the buoyancy is increased; and can make photovoltaic board 2 form the toper after photovoltaic board 2 locks, shelter from photovoltaic board 2's front, so, when running into weather deep sunless time or when having ice load or other floaters, can draw up photovoltaic board, make photovoltaic board 2 top and buoyancy post 1 agree with, thereby protection photovoltaic board 2 openly suffers rainwater erosion, in addition, photovoltaic board 2 is the toper, can also effectively reduce the effect of ice load to buoyancy post 1, photovoltaic board 2 at this moment can be seen as the icicle.
When the buoyancy column is installed, the installation section 22 can be welded or hinged with the buoyancy column 1. When hinged, different states of the photovoltaic panel 2 can be added, meeting different requirements. And the hoist engine 6 can be arranged on the mounting table 5 in the buoyancy column 1 to avoid the damage of the hoist engine 6 caused by seawater and illumination and ensure the service life of the hoist engine 6. In order to connect the winch 6 and the photovoltaic panel 2, a lifting lug may be disposed on the free section 21 of the photovoltaic panel 2 for the connection rope 4 to pass through, and the other end of the connection rope 4 is connected to the winch 6 through a through hole 8 (refer to fig. 1) on the buoyancy column 1. Specifically, a fixed pulley 7 is arranged in the buoyancy column 1, and the connecting rope 4 passes through a through hole 8 (refer to fig. 1) in the buoyancy column 1, changes the direction through the fixed pulley 7, and is connected with the winch 6. When the device works, the connection rope 4 is retracted and released by controlling the positive rotation and the negative rotation of the winch 6. The connecting rope 4 referred to in the application is preferably a steel wire rope, and the light aging can be avoided while the strength is ensured.
In other embodiments, the winch 6 may be replaced by a hydraulic rod, specifically, the turning of the free section 21 may be achieved by the extension and contraction of the hydraulic rod, and those skilled in the art will understand that other structures, such as a ball screw, may be used for driving the turning of the free section 21, and all are within the protection scope.
For the concrete structure and shape of the photovoltaic panel 2, reference can be made to fig. 4 and 5, wherein the mounting section 22 is a trapezoidal panel whose vertical projection is trapezoidal; while the free section 21 is an arc panel with a trapezoidal vertical projection, and it needs to be ensured that: when the free section 21 is closest to the buoyancy column 1, that is, when the photovoltaic panel 2 is buckled, the free section 21 is attached to the buoyancy column 1, so that complete protection of the interior of the photovoltaic panel 2 can be realized. In addition, the bottom edge of the free section 21 is common to the bottom edge of the mounting section 22, and the height of the free section 21 is greater than the height of the mounting section 22, so that the mounting section 22 can be completely shielded during the folding of the free section 21 to protect the photovoltaic panel 2. The specific size of the photovoltaic panel 2 needs to be set in combination with the diameter of the buoyancy column 1 and is within the protection range. The structure of the photovoltaic panel 2 can be in other shapes as long as the structure can meet the requirements of the large lower part and the small upper part, so that the photovoltaic panel 2 is tapered after being folded.
In view of the above, there are various ways to achieve the unfolding and buckling of the photovoltaic panel 2, one of which is to hinge the photovoltaic panel 2 to the floating column 1 (shown in fig. 1), and the specific shape of the photovoltaic panel 2 is not particularly limited; secondly, the photovoltaic panel 1 and the buoyancy column 1 can be welded, and the photovoltaic panel 2 is arranged to be a foldable structure, so that the photovoltaic panel 2 can be unfolded and buckled (shown in fig. 2); thirdly, the photovoltaic panel 2 may be hinged to the buoyant column 1 and the photovoltaic panel 2 may be provided as a collapsible structure (combination of fig. 1 and 2). Of the above three modes, the third is the most preferable mode.
In order to limit the position of the buoyancy column 1, the end of the buoyancy column 1 in the sea surface is fixed by four mooring members in different directions, for example, the mooring members may be uniformly arranged along the circumference of the buoyancy column 1, as shown in fig. 8. In practice, the mooring element may be a chain 9, but also a mooring line. Carry on spacingly to buoyancy post 1 through four directions, can prevent effectively that 1 position of buoyancy post from changing, accomplish the relatively fixed to buoyancy post 1 for buoyancy post 1 is more stable. In practice, the number of mooring elements may also be varied, for example three or another number may also be arranged evenly along the circumference of the buoyancy column 1.
On the basis of the technical scheme, the offshore wind turbine assembly disclosed in the application is further provided with a radar (not shown in the figure) for observing weather, the radar is in signal connection with the winch 6 and/or the driving piece, and the radar can be installed at the wind turbine main body. When the radar works, when the radar detects severe weather such as cloudy weather or rain, snow, ice, hail and the like, the photovoltaic panel 2 can be controlled to be folded so as to protect the photovoltaic panel 2; and when the radar detects that the weather is clear and is suitable for collecting solar energy, the photovoltaic panel 2 is controlled to be unfolded. Automatic control is realized by adopting the radar and controlling the radar, and the sensitivity and the real-time performance of control are improved.
In a particular embodiment, the buoyancy columns 1, anchor chains 9 and photovoltaic panels 2 may be transported apart for ease of transportation and assembled after transportation to a machine site. In practice, also can assemble photovoltaic board 2 and buoyancy post 1 earlier, transport after drawing in photovoltaic board 2 in the transportation to reduce on-the-spot concatenation process, improve assembly efficiency.
