Description
Technical field
The present invention relates to marine tidal-current energy technical field of power generation, a kind of novel marine tidal-current energy energy gathering cap.
Background technology
Trend is primarily referred to as the regular sea water stream produced with tidal phenomena, and trend changes its size and Orientation twice daily.Marine tidal-current energy is different from tide, tide is flood tide and the sea water lifting caused of ebbing tide, trend is the horizontal movement of sea water, energy entrained by tide is potential energy, can be used to use the modes such as generating that construct a dam to store water, marine tidal-current energy generating is then to directly utilize the machinerys such as tidewater water impact impeller to drive generator operation to generate electricity.
Compared with conventional energy resource, marine tidal-current energy has the advantage that cleaning is renewable；Energy gross reserves is big；Change regular measurable；Need not block Hai Jianba, and generating set is generally immersed in sea water, less on marine organisms impact, environment will not be produced three-waste pollution, the most not exist and common in conventional hydropower construction take the problem such as farmland, immigration allocation.
Owing to possessing above-mentioned advantage, the exploitation of marine tidal-current energy is by pay attention to day by day.Marine tidal-current energy resource is the important supplement of future source of energy, particularly significant in the energy supply solving island.The capacitation of current marine tidal-current energy generator group is inefficient, and the advantage of vertical axis TRT is all to generate electricity when direction of tide is contrary, has certain advantage.Partly covering vertical-axis tide energy generating set and can be effectively improved the efficiency of marine tidal-current energy generator group in this project, improves the utilization rate of marine tidal-current energy, promotes the exploitation of this new forms of energy of marine tidal-current energy.
The defect of the most conventional marine tidal-current energy generator group is: use common horizontal shaft water-turbine, trend flow direction be perpendicular to turbine shaft to when, the blade rotation direction of the hydraulic turbine, by having time of half with to carry out flow path direction contrary, flows the rotation hindering the hydraulic turbine on the contrary.If Design of Hydraulic Turbine operating mode is for rotating clockwise, when turbine blade forwards left side to, direction of rotation will be contrary in trend flow direction, hinder the rotation of the hydraulic turbine, reduce its capacitation efficiency.
Summary of the invention
The technical problem to be solved is to provide a kind of novel marine tidal-current energy energy gathering cap, and this guiding device has suitable convergence effect to current, can improve the capacitation efficiency of tidal current energy generating equipment, higher to marine tidal-current energy utilization rate.
Above-mentioned technical problem can be solved by following technological means: a kind of novel marine tidal-current energy energy gathering cap, the inside of described guiding device is cavity type float structure, its housing includes upper and lower two surfaces and is perpendicular to the side that horizontal plane is arranged, the upper and lower surface of described guiding device is the planar structure being parallel to horizontal plane, have two holes in upper and lower surface, ballast water and air can be injected and carry out adjustment housings at buoyancy；One of them wall of the side of guiding device is to comprise diversion division and the curved wall of impeller auxiliary section, the described impeller auxiliary section semi arch being projected as being inwardly recessed in the horizontal plane, the described diversion division curve being projected as being inwardly recessed in the horizontal plane, diversion division is symmetricly set on the both sides of impeller auxiliary section and is connected with impeller auxiliary section.Use cavity type float structure, it is possible to achieve deep water fairway operation, make full use of the marine tidal-current energy of profundal zone.Under the guiding function of diversion division, turn to concentration impact impeller when using trend to flow through diversion division, make impeller rotate, the utilization ratio of marine tidal-current energy can be improved.Perforate can increase guiding device stability in water by injection ballast water to change buoyant condition up and down.
For being actually needed, above-mentioned guiding device can be to be designed to two kinds of forms, and one is unilateral guiding device, and one is Double-edge type guiding device.Wherein, the wall that the side of the structure of unilateral guiding device is relative with curved wall is the planar wall being projected as straight line at horizontal plane, and described planar wall is connected with described curved wall.And the side of Double-edge type guiding device has two symmetrically arranged curved walls, two curved walls are directly connected to each other.
It is connected by being located at the connecting plate above wing flap type horizontal shaft water-turbine between guiding device, connecting plate is provided with axis hole, being provided with the bearing that the rotating shaft with wing flap type horizontal shaft water-turbine matches in axis hole, the rotating shaft of wing flap type horizontal shaft water-turbine through bearing and is connected with TRT by shaft coupling.Connecting plate can play fastening and strengthen the effect of bonding strength.
The invention have benefit that: compared with prior art, guiding device have employed cavity type structure, has buoyancy, can be configured and operation in deep water fairway, ballast water, adjusting means buoyancy in water can be injected as guiding device internal cavities by the perforate of guiding device upper and lower surface；Additionally, during this device uses, trend is through the effect of guiding device, and its flow direction will change, and current are by more vertical impact turbine blade, and it is contrary with turbine blade direction of rotation not have water (flow) direction.This device molded line is simple, is on the one hand easy to manufacture, and the most adjacent two guiding devices can produce the most favourable effect, further enhance the capacitation efficiency of the hydraulic turbine.
