Description
Technical field
The utility model relates to a kind of tidal energy collection and conversion device, and particularly a kind of tidal energy is collected air switching energy device.
Background technique
Well-known waterpower, wind energy, solar energy has almost been developed coda.About 3.6 hundred million square kilometres of the global ocean gross area accounts for 71% of the earth's surface gross area.About 3800 meters of the mean depth of global ocean, 11034 meters of maximum depths.The volume of global ocean is about 13.7 hundred million cubic kilometers, takes up an area more than 97% of ball Total Water.The huge kinetic energy of sea wave as well as tide is the waterpower that continues in the ocean, wind energy, after the solar energy unique be not developed and energy more than waterpower, wind energy, the new energy that solar energy is huge.Tidal energy is that the gravitation of the celestial bodies such as the moon and the sun makes ocean water level generation tidal fluctuations and the energy that produces, is a kind of cleaning, free from environmental pollution, the renewable energy sources that do not affect the ecological balance, and the major way of tidal energy utilization is generating.World ocean tidal energy reserves are about 2,700,000,000 kw, if all convert electric energy to, every annual electricity generating capacity is approximately 1.2 trillion kwh.Following pollution-free, the cheap energy will be eternal tidal energy, and present pilot is developed the power station of tidal energy in the world, and the main mode of utilizing of tidal energy is tidal power generation.In the middle of the prior art, because tidal power generation also is in the starting stage, therefore present tidal power generation also mostly is in the stage of original utilization: as select the amplitude of morning and evening tides greatly, will have several meters at least; The second coastal landform must can be saved a large amount of seawater, and can carry out civil works, can be in the river mouth or the bay build a dam, to form natural storage, the hydraulic generator unit just is contained in the sea dam.This tidal power generation mode, when building, be subject on the one hand the restriction of natural condition, must select suitable place just can build, on the other hand, because there is the variation of tidal range and head, can cause the intermittent of generating, simultaneously because generator set directly is immersed in the middle of the seawater, the situations such as therefore easy corrosion, contamination.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of morning and evening tides tidal range and head impact that overcomes is provided, and be not subjected to the tidal energy physical environment constraint, that power supply is continuous to collect air switching can device.
A kind of tidal energy is collected air switching energy device, its structure outline is: include tank body, support, 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, and tank body is supported on the support.
The tidal energy of this structure is collected and is converted to air energy device, supporting frame is fixed in the seabed, make 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.
This pressurized air can directly be pressed into the wind-tunnel storage, also can directly drive the device with two-way airflow direction operation and do work or generating, even can conveniently transport by the charged pressure tank, finishes tidal energy to collection and the conversion of air energy
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.
In sum, the utility model following advantage compared to existing technology:
Tidal energy of the present utility model is collected air switching and can be had by device,
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 processing and anti-silt etc. reduce a large amount of deep ocean work costs than difficult problem.
3, when this tidal energy collect air switching can device because only have a tank body and contact with sea water to avoid tidal power station because low water head, the large forms of electricity generation of flow.Fluctuation tidal water flow opposite direction, so 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
In a word, collect air switching energy device as long as there is the existence place of tide and sea wave that tidal energy of the present utility model can be installed very easily, therefore as long as there is seawater fluctuation just can collect ocean energy, the large small plant according to the area of ocean can be that small power station also can be the power station cluster.
