The bottom of semi-spherical portion 11 is to the shortest distance of pedestal immersed tube 55 during by floating.
Wherein, the structure of small-sized wind power generator 30 is referred to the prior art, and details are not described herein again.
Specifically, floating pedestal 10 further includes sealer 15, sealer 15 and the side of the separate semi-spherical portion 11 in overturn-preventing portion 13
It connection and is connect with pylon 31, sealer 15 is by the closure of openings of float chambers 101.
In order to improve the stability of small-sized wind power generator 30, floating pedestal 10 further includes dowel bar, dowel bar
One end is connect with the inner wall of semi-spherical portion 11, and the other end of dowel bar is connect with pylon 31.
Detailed, the quantity of dowel bar is multiple, and multiple dowel bars are layered, concyclic with the tie point of semi-spherical portion 11
And the concyclic disc dowel bar parallel with the end face of semi-spherical portion 11 is same layer；
Along the vertex of semi-spherical portion 11 to the direction of end face, the weight of every layer of dowel bar is sequentially reduced.
In more detail, the weight of dowel bar is gradually reduced from 11 junction of semi-spherical portion to 31 junction of pylon.
In the present embodiment, the number of plies of the dowel bar of floating pedestal 10 is two layers, respectively the first muscle bar layer 172 and the
The junction of two muscle bar layers 174, the first muscle bar layer 172 and semi-spherical portion 11 is compared to the company of the second muscle bar layer 174 and semi-spherical portion 11
Place is met closer to the vertex of semi-spherical portion 11, the junction of the first muscle bar layer 172 and pylon 31 is compared to the second muscle bar layer 174 and tower
Vertex of the junction of frame 31 more far from semi-spherical portion 11.
It that is to say that the first muscle bar layer 172 and the second muscle bar layer 174 are interspersed, even if there is some dowel bars in this way
The undesirable conditions such as fracture occur, can also there is certain support each other, avoid overall structure avalanche simultaneously.
It is understood that other than the scheme of two layers of dowel bar, it is possibility to have the dowel bar layer of other quantity
Scheme can equally select the above-mentioned scheme being staggered, to improve reliability of structure when setting.
Specifically, the apex of semi-spherical portion 11 has a transmission hole 112, transmission hole 112 be used for for electric power transmission cable and
Communication cable passes through so that 30 electricity of small-sized wind power generator can be transferred to other than small-sized offshore wind power system 100
Place, and the control instruction in the place other than small-sized offshore wind power system 100 is enabled to be conveyed to small wind hair
Motor 30.
It is conducive to integrally-built regular, raising stability in apex 112 one side of setting transmission hole, on the other hand,
The channel of a transmission being to provide, ensures the actually available of power generation.
In view of encountering thunderstorm weather sometimes, small-sized offshore wind power system 100 includes lightning rod 60, lightning rod 60
Suspended frame 51 is set to, floating pedestal 10 is made of insulating materials.It in this way can be to avoid thunder and lightning directly to small-size wind power-generating
Machine 30 damages, and ensures the safety of total system.
About pedestal immersed tube 55, particularly, a part for pedestal immersed tube 55 is inserted into sea bed 200.And it is with vertical
Mode is being axially inserted into sea bed 200.
More particularly, limiting cable 53 is connected to the edge of suspended frame 51, the mutual line of 55 installation point of pedestal immersed tube
The outer profile of the figure of composition is similar to the profile of suspended frame 51.
There can be better fixed effect on sea bed 200 in this way, avoid sea bed 200 is excessively soft from influencing pedestal immersed tube 55
Positioning so that pedestal immersed tube 55 is there are one mutual stabilization.
The principle of the present embodiment is：
Marine wind energy is huge, rationally can solve the power supply problem on some island using wind energy to generate electricity, in order to
Can allow needs the island for powering and being unsuitable for carry out Large marine assembling to power using wind-force, the present embodiment design
A kind of small-sized offshore wind power system 100.
Specifically, the semi-spherical portion 11 of floating pedestal 10 and overturn-preventing portion 13, after being installed in place, semi-spherical portion 11 is located at outstanding
In floating frame 51, the displacement that semi-spherical portion 11 is located at part in the sea needs the buoyancy for reaching draining to be more than floating pedestal 10 and small
The requirement of the gravity of type wind-driven generator 30 can sink, also, even single to avoid small-sized wind power generator 30 in this way
Floating pedestal 10 and small-sized wind power generator 30 are positioned over can not also sink in the sea, small-sized when in this way can be to avoid there is emergency
Wind-driven generator 30 sinks to marine.
Can be relatively more in view of stormy waves in the sea, therefore there is provided overturn-preventing portions 13 to prevent seawater from entering semi-spherical portion 11.
Further, it is contemplated that rainy situation, being also provided with sealer 15 can be with outer portion every keeping away inside pedestal 10 to float
Exempt to increase gravity into water, cause to sink.
In order to further improve stability, the present embodiment devises dowel bar, by small-sized wind power generator 30
Installation site and the design of the distribution of weight of dowel bar so that 10 whole weight of small-sized wind power generator 30 and floating pedestal
Power is concentrated mainly on semi-spherical portion 11 and concentrates on the region of semi-spherical portion 11 down, utmostly ensures and is not easy during whole floating
Topple over, it is ensured that the reliability used.
And in order to further enhance reliability during total system power generation.The present embodiment has used fixation kit so that more
A floating pedestal 10 is tied each other.
Suspended frame 51 can further increase buoyancy, and multiple floating pedestals 10 are collaborated, more whole
Then body connects pedestal immersed tube 55 by limiting cable 53 so that it is multiple floating pedestals 10 can in certain range quilt
It limits rather than is completely fixed or freely drift completely, so not only will not be completely firmly anti-with the impact of wave, but also will not be by
Lead to not reliably generate electricity in freely drifting.
And the design of 53 length of cable is limited, and floating pedestal 10 will not be drawn by the direction that pedestal immersed tube 55 sinks
It drags, is only limit the region of floating.
It is designed by the guarantee of guarantee design and the floating of a series of this stability so that 30 energy of small-sized wind power generator
It is enough at sea to generate electricity, whole system is mounted near some island, you can provide support for the electricity consumption on island, both
Clean energy resource is utilized, avoids polluting, and saved power supply cost, it is very practical.
In conclusion the small-sized offshore wind power system 100 of the present invention is by floating pedestal 10, small-sized wind power generator
30 and the cooperation of fixation kit, realize the function of the marine power generation near island, both saved cost do not have to set up it is big
Type offshore wind turbine, the drawbacks of in turn avoiding electricity shortage that traditional diesel-driven generator 33 brings and generate pollution, structure can
It leans on and stablizes.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, that is made any repaiies
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
