Embodiment
Below in conjunction with drawings and Examples, concrete enforcement of the present utility model is described further.
This model utility provides a kind of offshore wind turbine compound bucket foundation combined with current power generation, is that a kind of structure is simple, easy installation and removal, can improves the fondational structure of current power generation water turbine capacitation.
Rapidly, conveniently boats and ships are stopped, and from accompanying drawing 1, offshore wind turbine bucket foundation 1 is provided with by ship post 2 structure in offshore wind turbine development, utilize and combine with current power generation by ship post 2, realize the comprehensive utilization of compound bucket foundation 1.Conveniently water turbine 7 is installed, design guide shell 4 structure.In order to adapt to severe ocean environment, bucket foundation 1 and guide shell 4 carry out prefabricated on the coast, use Reinforced Concrete Materials to make.Guide shell 4 is made up of ladder-type cylindrical body and guide sleeve 3, the streamlined outer wall energy of guide shell 4 effectively reduces the impact force of current to guide shell 4, by bolt, guide sleeve 3 and guide shell 4 are attached to by ship post 2, ship post 2 will be leaned on as supporting structure, save the cost making separately pile foundation, the stability simultaneously for guide shell 4 has certain benefit.
See accompanying drawing 2, be guide channel 9 in the middle part of guide shell 4, as the water inlet of current power generation water turbine 7.Guide shell 4 inside is hollow design, make to form interlayer between guide shell 4 outer wall and guide channel 9 inwall, for water storage or air, the height of ladder-type cylinder is determined according to the depth of water, should ensure that the vent 6 of upper cover is positioned on sea, inside and outside convenient, carry out the exchange of water or air.
Guide channel 9 is positioned at the neutral position of guide shell 4, and by marine boundary layer and top layer Lidar Equation, the ocean current flow velocity of middle aqueous layer is larger.Guide channel 9 Cross section Design is circular, and fairshaped inwall can reduce the erosion of current to wall, reduces the generation of cavitation phenomenon.According to Venturi tube principle, when flow is identical, sectional area is less, flow velocity is larger, guide channel 9 is designed to two end sections large, the form that intermediate cross-section is little, increase the flow rate of water flow at intermediate cross-section place, water turbine 7 is arranged on intermediate cross-section place, and the energy that water turbine 7 obtains from current have also been obtained lifting, even low flow velocity also has higher capacitation power.Affect by flux and reflux, current direction can change, and guide channel 9 two ends are set to isometrical large-section, can make the current of water turbine 7 simultaneous adaptation both direction, brings convenience for catching energy.
See accompanying drawing 3, in guide channel 9, intermediate cross-section place is provided with supporting frame 8, uses concrete material to make, while the supporting frame 8 of triangular structure ensures base fixed, reduce the self blocking of supporting frame 8 pairs of current, reduce the negative effect that water turbine 7 capacitation is exported.Supporting frame 8 there is screw, water turbine 7 barrel has flange, flange has the screw with supporting frame 8 correspondence, coordinated by bolt and water turbine 7 is arranged on supporting frame 8, convenient installation, dismounting water turbine 7.
After water turbine 7 installation, by guide shell 4 towage to bucket foundation 1 position, because now guide shell 4 inner clamps sheaf space is air, rely on buoyancy can carry out towage very easily.After arriving bucket foundation 1 place, the position of adjustment guide sleeve 3 and guide shell 4, bolt is used to be attached to by ship post 2 by guide sleeve 3 and guide shell 4, by vent 6 toward the water filling of guide shell 4 inner clamps sheaf space, rely on gravity that guide shell 4 is sunk gradually along by ship post 2, when water turbine 7 sinks to suitable water layer, stop adding water toward guide shell 4, water turbine 7 carries out work.When guide shell 4 sinks, by arranging water line or position-limit mechanism, ensure that guide shell 4 does not collide with bucket foundation 1.
When water turbine 7 break down need maintenance time, by vent 6 by the water of guide shell 4 inner clamps sheaf space extract out, overall structure rely on buoyancy automatically emerge, technician can stand in and keep in repair by ship post 2 or aisle 5 carry out water turbine 7.
It will be clear that the utility model is not limited to embodiment here, those skilled in the art are according to announcement of the present invention, and conceiving the apparent improvement made by the utility model and modify all should within protection domain of the present utility model.
