Description
Technical field
The utility model relates to a kind of generator, relates in particular to a kind of generator that utilizes seawater stream to drive generating.
Background technique
Ocean current is broadly divided into following a few class by its origin cause of formation:
(1) drifts about: the ocean current that forms by the drageffect of wind.
(2) geostrophic flow: in the ocean of ignoring the effect of turbulent skn friction power, the permanent current when seawater horizontal pressure gradient force and horizontal geostrophic deviating force balance.
(3) trend: oceanic tide also has periodic bottom horizontal flow sheet in fluctuation, this bottom horizontal flow sheet is called trend.
(4) flow compensated: replenish that seawater runs off and the ocean current that forms by the seawater stream in another marine site.Horizontal flow compensated and vertical flow compensated are arranged
(5) rivers and creeks earial drainage: owing to the sea of going into of river flow, near the caused marine stream in the sea area the river mouth is called the rivers and creeks earial drainage.
(6) rip current: wave by the off-lying sea to seashore be transmitted to that the wave breaking band produces when broken by the ocean current of bank to the deep water direction.
(7) along shore current: the ocean current that is parallel to the seashore motion that wave is produced after seashore is transmitted to the crushed zone fragmentation by the off-lying sea.
Ocean current is ubiquity in the ocean, actual flow field is the complex flowfield after the combination of above all kinds of ocean currents, according to the difference of the difference in geographical position, the fluctuation time of tide, tidal stencils, sea situation, seawater physical property, make various places take place to change in ocean current flow field constantly at each.According to the experience of marine hydrology investigation, the ocean current level to the flow velocity vertical line regularity of distribution is: the surface current speed maximum reduces gradually along depth direction.
In above-mentioned fluidised form, clocklike be the trend that tidal motion produces relatively.
Tidal energy is the ocean energy that occurs with the potential energy form, is meant the potential energy of the water that seawater tidal bulge and ebb form.The tidal phenomena of seawater fluctuation is caused by the earth and celestial bodies motion and the interaction between them.In the process of the potential energy of high tide, ebb tide water exchange, i.e. in the fluctuation tide process, be accompanied by the conversion of potential energy and kinetic energy.
In a lunar day (24 hours 50 minutes), for once a climax and a Lower Low Water are called full-time tide.A full-time tide process is roughly: ebb tide slack water (potential energy minimum, flow velocity is near 0)---rise and to rise that (potential energy begins to increase gradually, flow velocity strengthens)---(the potential energy rising trend is the strongest for the urgency that rises, the flood strength maximum)---slack water (potential energy maximum that flood tide, flow velocity is near 0) (potential energy is with the gesture maximum for the urgency that falls---(potential energy begins to diminish, and flow velocity increases, and turns to) rises and falls---, ebb current flow velocity maximum)---the ebb tide slack water, the time of being separated by between its climax and the low tide is approximately 12 hours 25 minutes.
For the semidiurnal tide marine site, in one day (refer to lunar day last 24 hours 50 minutes) significantly climax of secondary is arranged, secondary is the low tide process significantly.---in the process of low tide---climax---low tide, the exchange rule and the full-time tide of potential energy and kinetic energy are basic identical in the secondary climax.
Morning and evening tides in actual ocean, river mouth, reason owing to complexity, often the fluctuation tide of morning and evening tides lasts, tidal stencils can deform, be that full-time tide can be divided into regular full-time tide and informal full-time tide, semidiurnal tide can be divided into regular semidiurnal tide and informal semidiurnal tide, but it still follow the exchange rule (seeing Fig. 1, Fig. 2) of potential energy and kinetic energy.
According to river mouth, marine site hydrologic survey experience for many years, this device is applicable to above-mentioned all kinds of ocean current fluidised form, according to the horizontal flow velocity of ocean current along the depth direction regularity of distribution, locate to relative water depth 0.6H (supposing that the depth of water is H) on the water body top layer, all can arrange this device, start the flow velocity requirement as long as the ocean current flow velocity reaches generator, just can be used for generating.
At present, utilize the project of oceanic tide generating, mainly utilize the potential energy of tiding tide, the layout of building a dam water turbine promotes water turbine with head difference and rotates generating.But this mode is to tide dynamic force conditional request height (tidal range is big), to landform, geologic requirements height, the addressing complicated condition, it is less to be suitable for the region, cost is high, the tide dynamic force condition of while malleable bay or tidal channel, tend to cause the unfavorable adjustment of subaqueous relief, influence the marine eco-environment of bay, water channel, be unfavorable for the comprehensive development and utilization of bay, water channel.
Summary of the invention
