A kind of floating energy co-generation system
Technical field
The present invention relates to new energy use technology field, particularly relate to the floating energy co-generation system of a kind of wind power generating set and Ocean Tidal Current Energy generator set.
Background technique
Wind power generating set and Ocean Tidal Current Energy generator set are two kinds of different power generation systems.Offshore wind turbine utilization be marine wind energy, in the time that wind speed is lower or while breaking down, wind power generating set generating efficiency can reduce, and even can not produce electric energy; The just kinetic energy of ocean current that Ocean Tidal Current Energy generator set utilizes, in the time that flow velocity is lower or while breaking down, also has the low not even phenomenon of generating of generating efficiency.
No. 201220713765.6 Chinese patent door frame fondational structure of marine wind energy and marine tidal-current energy generating " simultaneously for ", provide a kind of by the system architecture of wind energy and marine tidal-current energy integration, but this fixed wind power generating set and Ocean Tidal Current Energy generator set co-generation system can only be applicable to Intermediate Water Depth and shallow water area, and rated output of generating set is less; Deepwater regions for the depth of water more than 60 meters and jumbo generator set, there is the deficiencies such as material consumption increase, constructional difficulties, cost increase in fixed system.
As can be seen here, above-mentioned existing energy co-generation system, in structure and use, obviously still has inconvenience and defect, and is urgently further improved.How to found a kind of collaborative generating that can really realize wind energy on the sea and energy by ocean current, and can be applicable to as required dark, the shallow water along the coast, the new floating energy co-generation system that rated power is high, capacity is large, constructability is built is that the current industry utmost point needs improved target.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of floating energy co-generation system, can really realize the collaborative generating of wind energy on the sea and energy by ocean current, and can be applicable to as required dark, the shallow water along the coast, rated power is high, capacity is large, constructability construction, thereby overcomes the deficiency of existing energy co-generation system.
For solving the problems of the technologies described above, a kind of floating energy of the present invention co-generation system, comprises wind power generating set, marine tidal-current energy generator group and buoyancy aid, wherein: the bottom of described wind power generating set is fixedly connected with buoyancy aid; The top of described marine tidal-current energy generator group is fixedly connected with buoyancy aid; Described buoyancy aid is across the sea floating and be connected on sea bed by anchor chain.
As a modification of the present invention, described buoyancy aid is made up of multiple cabins.
Described wind power generating set mainly comprises impeller, cabin and tower cylinder, and its tower cylinder bottom is fixedly connected with buoyancy aid by flange.
Described marine tidal-current energy generator group mainly comprises water wheels, cabin and supporting structure, and the top of its supporting structure is fixedly connected with buoyancy aid by flange.
Adopt after such design, floating energy co-generation system of the present invention, becomes a kind of new power generating system offshore wind turbine and the design of Ocean Tidal Current Energy generator set, and it at least has the following advantages:
1, realized the function of simultaneously utilizing wind energy on the sea and energy by ocean current generating;
2, overcome because wind speed is lower, flow velocity when lower or offshore wind turbine, Ocean Tidal Current Energy generator set one of them while breaking down, generating efficiency reduces the defect that maybe can not generate electricity;
3, Intermediate Water Depth and shallow waters be both applicable to, more applicable to the more than 60 meters deepwater regions in the depth of water;
4, generating set capacity is large, rated power is high, be beneficial to construction, has also reduced cost when improving energy utilization rate.
Brief description of the drawings
Above-mentioned is only the general introduction of technical solution of the present invention, and in order to better understand technological means of the present invention, below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
Fig. 1 is the structural representation of a kind of floating energy of the present invention co-generation system.
Fig. 2 is the plan structure schematic diagram of a kind of floating energy of the present invention co-generation system.
Fig. 3 is the structural representation of looking up of a kind of floating energy of the present invention co-generation system.
Embodiment
Refer to shown in Fig. 1, Fig. 2 and Fig. 3, a kind of floating energy of the present invention co-generation system is mainly made up of wind power generating set, marine tidal-current energy generator group and buoyancy aid three parts, wind power generating set bottom is fixedly connected with buoyancy aid 5, marine tidal-current energy generator group top is fixedly connected with buoyancy aid 5, and buoyancy aid 5 is across the sea floating and be connected on sea bed by anchor chain 10.
Further specifically, wind power generating set can adopt any existing or follow-on wind-power electricity generation group framework as required, conventionally mainly comprises impeller 1, cabin 2 and tower cylinder 3, and wherein, the bottom of tower cylinder 3 can be connected with buoyancy aid 5 by flange 4.
Marine tidal-current energy generator group also can adopt any existing or follow-on Ocean Tidal Current Energy generator set framework as required, taking the unit that mainly comprises water wheels 6, cabin 7 and supporting structure 8 as example, the top of its supporting structure 8 can be connected with buoyancy aid 5 by flange 9.
Buoyancy aid 5 inside are all divided into several cabins, by ballast, provide the buoyancy of combination wind generator group, ensure normal load draught and stability.
Anchor chain 10 is fixed on seabed novel floating energy co-generation system, plays a part constraint and fixed system.
The present invention adopts floating structure to design and supports wind power generating set part, and therefore construction is relatively easily a lot, and applicable to 60 meters of above regions of the depth of water.After system Construction, the wind power generating set that impeller 1, cabin 2, tower cylinder 3 form is positioned at top, sea level, utilizes offshore wind power generation; Meanwhile, the Ocean Tidal Current Energy generator set that water wheels 6, cabin 7, supporting structure 8 form is positioned at below, sea level, utilizes the kinetic energy power generation of ocean current; Both utilized wind energy, and utilized again energy by ocean current, comprehensive electric generating efficiency is high, and cost is low.
