Wherein, also comprise energy storage annular dam body, the bottom of this energy storage annular dam body is connected with the seabed is airtight, and its top is higher than the sea level, flow channel also is set to be communicated with the inside and outside of this standby annular dam body in it, also is provided with the water generating unit in the described flow channel.Wherein, also comprise the gate that this flow channel is opened and closed in the described flow channel.
Wherein, the water generating unit of described energy storage annular dam body only comprises water turbine, and is then shared with described annular dam body for the surplus equipment of water generating unit.
In the utility model, because dam body has been arranged in the ocean, thereby it is not subjected to the restriction in geographical position, and the removal problem of yet not taking over the land for use and immigration allocation problem can not impact shipping yet, and be very reasonable and practical.
Description of drawings
Fig. 1 is an embodiment's of a kind of ocean of the utility model reservoir tidal power generation system a structural representation;
Fig. 2 be embodiment illustrated in fig. 1 in an embodiment's the sectional view of annular dam body.
Embodiment
The utility model is elaborated below in conjunction with accompanying drawing.
With reference to figure 1, illustrate an embodiment's of a kind of ocean of the utility model reservoir tidal power generation system structural representation.
As shown in the figure, it has comprised annular dam body 12, because it be annular, and then has comprised and is positioned at its inner inner space 121, and be positioned at its outside space 122; The upper end of described inner space 121 is uncovered, and the lower end connects the seabed; And ocean just, the space 122 of described outside, this annular dam body 12 places the ocean.
The bottom surface of described annular dam body 12 and the seabed of described ocean 11 fit tightly to seal the lower end of described inner space 121, prevent that seawater from flowing in the bottom of described annular dam body 12 or flow out in described inner space 121.
The inner space 121 of described annular dam body 12 also is used to hold seawater.
The height of described annular dam body 12 is higher than the sea level to prevent seawater and flow into from the top of described annular dam body 12 or to flow out in described inner space 121.
With reference to figure 2, illustrate embodiment illustrated in fig. 1 in an embodiment's the sectional view of annular dam body.As shown in the figure, as can be seen, its cross section presents trapezoidal, and is up-narrow and down-wide so that whole more firm.Comprised flow channel 123 in this annular dam body 12, and water generating unit 124.
Wherein, described flow channel 123 is for being communicated with the path of described inner space 121 and space outerpace 122, seawater in described inner space 121 and the space outerpace 122 only can flow via this path (because the lower end and the seabed 11 of described inner space 121 fit tightly, the upper end then is higher than the sea level, and sea level herein should be Above Sea Level at the incoming tide).
124 of described water generating units are arranged in the described flow channel 123, and are concrete, and the water turbine of described water generating unit 124 is arranged in the described flow channel 123 and changes with the energy that the water in the described flow channel 123 is flowed.
Following brief description, the working procedure of utilizing ocean tidal power to carry out water generating embodiment illustrated in fig. 1:
When high tide, sea-level rise, owing to be communicated with by described flow channel 123 between the inner space 121 of described annular dam body and the space outerpace 122, thereby will inevitably make seawater pour in described inner space 121 by described flow channel 123, and the kinetic energy of current has just driven described water turbine rotation, and then the other parts of described water generating unit 124 just are converted into electric energy;
When seawater at ebb tide, the sea level reduces, owing to be communicated with by described flow channel 123 between the inner space 121 of described annular dam body and the space outerpace 122, thereby will inevitably make the seawater in the described inner space 121 pour in described space outerpace 122 by described flow channel 123, and the kinetic energy of current has just driven described water turbine rotation, and then the other parts of described water generating unit 124 just are converted into electric energy;
So no matter in that flood tide or can generate electricity at ebb tide.
As seen, because whole system of the present utility model is arranged in the ocean, it is not subjected to the restriction of geographical conditions, can not influence the shipping in rivers navigation channel yet, and simplicity of design is rationally convenient.
In another embodiment of the present utility model, also comprise the energy storage annular dam body that is arranged in the ocean.This energy storage annular dam body has comprised flow channel and water generating unit equally, the structure of itself and described annular dam body roughly the same, this point can be with reference to embodiment illustrated in fig. 1.
Its effect is that meeting continues one long period after high tide reaches full sea, if only have annular dam body shown in Figure 1 then during this period of time can't generate electricity, thereby is provided with the annular dam body of described energy storage.This energy storage annular dam body is at the incoming tide, and its flow channel is all closed, thereby makes the inner space of described energy storage annular dam body keep empty state.After reaching full sea, because this moment, annular dam body shown in Figure 1 can't generate electricity again, so time is opened the gate of described energy storage annular dam body, the seawater of space outerpace pours in the inner space of described energy storage annular dam body, thereby reaches the purpose of generating electricity when full sea.
And ought can make in a period of time that also annular dam body shown in Figure 1 can't generate electricity at ebb tide.So, when beginning at ebb tide, the closing gate of described energy storage annular dam body flows out with the water of avoiding its inner space.When tidewater moves back described to the greatest extent annular dam body can't generate electricity the time again, then this moment the gate of described energy storage annular dam body is opened, thereby made the seawater of its inner space gush out to space outerpace, thereby realize the purpose of generating by described flow channel.
In concrete realization, described energy storage annular dam body can adopt oneself independently hydroelectric power unit, is separate with described annular dam body promptly.Perhaps, in the described energy storage annular dam body water turbine only is set, and remaining water generating equipment and described annular dam body are shared.
In addition, because annular dam body or energy storage ring dam body in the utility model have formed the inner space that is not subjected to external interference, thereby mariculture can be carried out in its inside.Driven a series of related industry.And, owing to when building described annular dam body or energy storage annular dam body, lay possibly from land, thereby can also build superstructure with commercial, inhabitation or sightseeing etc. based on this to the road surface of described annular dam body or energy storage annular dam body.
