Description

A kind of tidal power generating device
Technical field
The utility model relates to a kind of tidal power generating device that utilizes tidal power generation.
Background technique:
The human society high speed development, energy consumption is huge, also faces problems such as limited resources exhaustion such as oil, rock gas, coal simultaneously.Therefore, the new energy of exploitation is all sought in research by each state.There is very long shore line in China, abundant, various and huge energy is being contained in the ocean: seawater had twice in one day 24 hours, and flood tide, twice ebb tide, rise one, in the process that falls, containing huge kinetic energy, how these kinetic energy being become electric energy is the human target of pursuing.
The model utility content
The purpose of this utility model is exactly that a kind of tidal power generating device that utilizes tidal power generation will be provided.The technical solution of the utility model is: the utility model comprises buoyancy aid, water turbine, hose-proof generator etc., described water turbine is arranged at the buoyancy aid middle part, the hose-proof generator outer periphery is equipped with fixed frame and is fixed in above the buoyancy aid hose-proof generator or the next door, the water turbine rotating shaft is connected with the hose-proof generator rotating shaft by gear or gear train, and the electric energy output end of hose-proof generator links to each other with submarine cable.
The utlity model has following advantage: the energy of (1), morning and evening tides is never exhausted, and the utility model can be used for a long time.(2), the utility model is simple in structure, little investment.(3), the utility model maintenance, easy maintenance.(4), the energy of the utility model absorption morning and evening tides is more direct, effective.

Fig. 2 is an another kind of structural representation of the present utility model.
Fig. 3 is the cross-sectional schematic of single buoyancy aid among Fig. 2.
Fig. 4 is the cross-sectional schematic of water turbine rotating shaft and a kind of gear Placement of hose-proof generator rotating shaft.
Embodiment
Specific embodiment below in conjunction with accompanying drawing further specifies the utility model.(but not being) to restriction of the present utility model.
As shown in the figure, the utility model comprises buoyancy aid 9, water turbine 1, hose-proof generator 6 etc.Described water turbine 1 is arranged at buoyancy aid 9 middle parts, and hose-proof generator 6 outer periphery are equipped with fixed frame 7 and are fixed in above the buoyancy aid 9.Water turbine 1 rotating shaft 3 is connected with hose-proof generator rotating shaft 13 by gear (or gear train) 5, and outer periphery is equipped with fixing frame 4.The electric energy output end of hose-proof generator links to each other with submarine cable.
Eight end angles of buoyancy aid of the present utility model are provided with the automatic controller 12 that can control the stay cord degree of tightness automatically, and stay cord 11 1 ends are connected with automatic controller 12, and the stay cord the other end is fixed in the sea-anchor 10.Automatic controller 12 is set, can makes buoyancy aid 9 keep balances with the degree of tightness that stay cord 11 is regulated in the fluctuation of seawater automatically.Sea-anchor 10 places the seabed, by stay cord 11 buoyancy aid 9 is placed among sea and the sea bed, and buoyancy aid can be selected to be arranged between the sea and sea bed of bigger relatively the bay of tidal energy and sea import and export.The height distance of buoyancy aid itself and sea bed is provided with selection, should make it on the ebb to lowest water level, and water turbine still can be worked.
Above-mentioned institute employing water turbine is known equipment, and described water turbine all can be worked in tidal bulge or ebb, and the rotating shaft sense of rotation of water turbine is same direction.Hose-proof generator also is known equipment, and hose-proof generator can be used in the seawater and works, and seawater can not infiltrate in the generator.Automatic controller 12 also is known device, and it is provided with capstan winch and remote-controlled motor.
Absorb morning and evening tides kinetic energy for ease of water turbine, buoyancy aid is the opening shape between front-back inboard to the water turbine placement of morning and evening tides water inlet and outlet turbine, and opening shape is horn-like.
Embodiment 1 is in order to illustrate principle of the present utility model as shown in Figure 1, so embodiment 1 has only a buoyancy aid, device has a water turbine in the buoyancy aid.And in fact, embodiment 2 as shown in Figure 2, in order to increase generating capacity, multiple arrangement can there be the buoyancy aid parallel connection of water turbine, many water turbine just can absorb more morning and evening tides kinetic energy like this, it is also more that corresponding many water turbine rotating shafts are delivered in the hose-proof generator rotating shaft energy, and hose-proof generator is with regard to exportable more electric energy.
As shown in Figure 2, water turbine 1 rotating shaft 3 is connected with hose-proof generator rotating shaft 13 by gear train 2.
As shown in Figure 2, hose-proof generator of the present utility model also can be set to two or many according to buoyancy aid situation in parallel, at this moment many water turbine also connecting means correspondence as described above distribute respectively with hose-proof generator and be combined into a plurality of tidal power generating devices.
As shown in Figure 1, hose-proof generator can be arranged at above the buoyancy aid.As shown in Figure 2, hose-proof generator also can be arranged on buoyancy aid next door, is provided with a support plate 8 below the buoyancy aid, and support plate 8 is connected to one with the buoyancy aid bottom surface, and hose-proof generator 6 is arranged on the support plate 8.
As long as enough buoyancy is arranged, the buoyancy aid shape can adopt any geometrical shape.
Like this, tide bulge and fall, the tidal water flow influent stream goes out water turbine, the water turbine rotating shaft is rotated, so water turbine just can be converted into mechanical kinetic energy to morning and evening tides kinetic energy, the water turbine rotating shaft is connected with the hose-proof generator rotating shaft by gear or gear train, and make the hose-proof generator generating, also just can be converted into electric energy to mechanical kinetic energy.
More than be specific embodiment of the utility model, all similar changes of doing according to above-mentioned design ought to belong to scope of the present utility model.
