Background technique
Utilize the device that wave generates electricity to have a lot.As in China Patent No. being 201220645685, notice of authorization day be Mays 29 in 2013 day, be called in the patent document of " formula of pulling in to shore wave-type electric generator " and disclose a kind of device that utilizes wave to generate electricity.Existingly utilize the device that wave generates electricity to have the following disadvantages: be all designed to be arranged on bank and utilize wave to generate electricity, therefore but the place of wave maximum is often positioned at the middle section in waters, can not be positioned at the place of waters Wave and draws Wave energy as required and flexiblely, therefore that Wave energy changes the ratio of electric energy into is little.
Model utility content
The offshore type oscillating water column electricity generating device that the utility model provides a kind of arbitrary position that can float in waters to generate electricity to utilize wave, has solved that existing wave-type electric generator can not flexibly be arranged on the position of waters Wave maximum and the Wave energy that causes changes the problem that electric energy ratio is little into.
Above technical problem solves by following technical proposal: a kind of offshore type oscillating water column electricity generating device, comprise floating drum and generator, in described floating drum, be provided with air chamber, the lower end of described air chamber is provided with wave import, the upper end of described air chamber is provided with air outlet, and described air outlet is provided with the turbine that drives described generator.During use, floating drum is swum in to the waters medium wave place that the wave is high, under the effect of wave, wave enters air chamber and forms the water column of up-down vibration through wave import, water column makes the gas in air chamber back and forth pass through the air outlet of air chamber upper end while doing up-down vibration motion, gas during back and forth by air outlet drives impeller machine rotate, turbine drives generator generating.
As preferably, described air chamber is big top and small bottom taper.Can guarantee that air-flow end pressure increases, can promote faster turbine and rotate.
As preferably, described air chamber is big top and small bottom taper shape.It is little that air-flow enters through conical section the flow resistance that air outlet is.Can improve generating efficiency.
As preferably, the both sides of described wave import substantially horizontal are provided with wave collecting board, form " V " shape troughs for collecting energy with wave import alignment between wave collecting board.When the technical program can make wave move in the troughs for collecting energy constantly shrinking, wave height constantly increases, speed constantly promotes, thereby plays the flow velocity of the air-flow that improves turnover air outlet, to improve the effect of generating efficiency.
As preferably, the bottom of described floating drum is provided with balance base.While generating electricity due to floating, electricity generating device can move up and down along with wave, and this up-down vibration can cause generating efficiency to reduce.Base can play the effect of the up-down vibration that slows down.
As preferably, described balance base is provided with anchor chain.Can further prevent that floating drum from moving up and down.
As preferably, described turbine is Bidirectional vane wheel machine.The wave process of rising and falling is all used for generating electricity, and generating continuity is better, efficiency is high.
The utlity model has following advantage: can flexibly be placed on according to the size of wave the water column that the medium wave place that the wave is high in waters produces by wave and generate electricity, flexible property during use is good, can to Wave energy, collect better.
