A kind of tidal-energy electric generator set, its structure outline is: include the device that tank body, support and two-way airflow drive direction operation, the upper and lower end of described tank body is uncovered, the upper end of tank body is entrance for the lower end of outlet, tank body, the cross sectional area of tank body outlet is less than the cross sectional area of tank body entrance, tank body is supported on the support, two-way airflow drives the device of direction operation or directly is arranged at the tank body outlet port or in the tank body outlet port air pipe is set, and the device of two-way airflow driving direction operation is set at the outlet end of air pipe.
The tidal-energy electric generator set of this structure, supporting frame is fixed in the seabed, makes the lower edge of tank body consistent with seawater lowest water level at ebb tide or be lower than lowest water level, and make uncovered the remaining of tank body upper end be exposed to the sea level, like this when variable height occurs in seawater in tank body
Supposing, is s second when wave increases to the h2 time from h1, and seawater compresses the air in the cavity of sealing
According to pressure=pressure/area
So in this s the time of second, the c back pressure=the a entrance section is long-pending/sectional area of c outlet, and a and c sectional area ratio are larger, and the pressure that c exports is larger, so the wave minor variations can be collected its energy very easily
In like manner, suppose when wave from h2 ebb tide to the h1 time be s second, the cavity of transducer forms negative pressure, and air just must become entrance from original c outlet with identical pressure and replenish, and has so just realized the purpose that is converted to aerodynamic energy is collected in the variation of small sea wave as well as tide.
The air of the energy harvester outlet ebb direction that can pressure rises is opposite as previously mentioned, even may all there be positive and negative alternate in the wave band of wave fluctuation, adopt two-way airflow to drive the device of direction operation, when pressurized air blows from top to bottom, flabellum rotates counterclockwise and drives the axle be embedded in the blade center and also be rotated counterclockwise, with blowing from the bottom up because the blade lean opposite direction by pressurized air, also just being equivalent to positive is to be rotated counterclockwise so just to have reached the homodromal purpose of bidirectional coaxial toward blowing down equally, then driven the assembly axis drive generator generating of direction operation by two-way airflow, perhaps acting has realized ocean energy arrives electric energy again to kinetic energy conversion
Described tank body is the structural arrangement that cross sectional area diminishes gradually by exporting to entrance.
Described tank body consists of by three sections, and the taper that comprises the straight section of outlet and the column of entrance and be positioned at the middle part is arranged, and the large end of taper is positioned at the ingress of tank body.
The shape of cross section everywhere of described tank body or be circular or be rhombus.
Circular tank body, the effect with economical with materials, the tank body of rhombus has the effect that reduces sea beat and easy construction.
The cross sectional area of the outlet of described tank body and entrance is than being inversely proportional to the oceanic tide ebb speed that rises, and requires size to be directly proportional with pressure to outlet, and outlet pressure requires to determine the cross sectional area ratio of described tank body outlet and entrance.
The device that described two-way airflow drives direction operation is Bidirectional vane wheel.
Described Bidirectional vane wheel is a pair of coaxial for comprising, with the same tilt angle of the number of sheets, and same area, the blade that arranges back-to-back that true dip direction is opposite consists of.
The described blade that arranges back-to-back is the integral type structure.
In sum, the utility model following advantage compared to existing technology:
Tidal-energy electric generator set of the present utility model has,
1, can realize very easily remote transmission.
2, there is not the specific (special) requirements of topography and geomorphology, need not specially to select the Haikou, bay, thus needn't select a building of river mouth building difficulty superelevation block the water dykes and dams, avoid depth of water dam length, construction, ground are processed and are anti-silting etc. than difficult problem, reduce a large amount of deep ocean work costs.
3, because only have a tank body and contact with sea water to avoid tidal power station because the forms of electricity generation of low water head, large flow.Fluctuation tidal water flow opposite direction, therefore the water turbine volume is large, steel consumption is many, the shortcoming difficult in maintenance of water inlet and outlet fabric structure complexity.
4, this transducer only with tank body and in the unit time what of tank body variation of seawater amount relevant, avoid tidal power station because tidal range and head often changed the intermittent inefficient shortcoming of the generating that brings in one day
