Background technique

Along with the development of society, people are increasing to demands for energy, and the wave energy in river, river, lake, sea is a kind of huge and pollution-free and be the reproducible energy, so wave-energy power generation more and more receives the concern and the attention of society.

The method and the device that obtain wave energy at present have a lot; But have complex structure mostly, wearout parts is many, the regular maintenance cost is high, antagonism natural disaster ability; Too rely on and implement environmental conditions (not having when electricity, no wave when wave is arranged), can't export more stable shortcomings such as the energy.

Summary of the invention

It is a kind of simple in structure that the purpose of the utility model is to provide; Long service life; Utilize the wave water column to drive generator blade; And part energy is converted into pressurized air and stores, when wave energy can't provide enough energy, then discharge pressurized air and drive the device that generator blade continues generating.

In order to address the above problem, the utility model is to realize through following technological scheme: semi-underground wave water column energy storage apparatus comprises the generator drive chamber; This device also comprises plenum chamber, air chamber, high-voltage tube; Said plenum chamber is provided with water intake and air outlet; The top of said air chamber is provided with pressure maintaining valve, and said high-voltage tube is provided with first safety check and second safety check, and described plenum chamber and air chamber are communicated with through high-voltage tube.

Further, plenum chamber and air chamber are ampuliform structure object, and the lower end is provided with buoyancy aid and ballast carrier, place water and are in half ascending and descending condition.

Further, plenum chamber is a tubular body, and air chamber is a tun, and plenum chamber is placed in the water and fixed.

Further, said plenum chamber inside also is provided with piston, and an end of said piston is arranged on the inside of high-voltage tube, and the connecting rod of piston connects the floating plate in the plenum chamber.

The said first safety check airintake direction is vertical air inlet; The airintake direction of said second safety check is horizontal air inlet.

Owing to used technique scheme; The energy storage apparatus of the utility model sinks along with wave carries floating carrying in water; The pressurized air of discharging drove generator blade and part energy is converted into pressurized air and is stored in the air chamber between utilization was drifted along; Air chamber stably carries out exhaust to the generator drive chamber through outlet valve, realizes lasting, stable generated energy source.

Embodiment

Below through specific embodiment the utility model is done further explain, but the utility model is not limited in following embodiment.

Embodiment

See also shown in Fig. 1 and 2, make the ampuliform object plenum chamber 10 and the air chamber 20 of two sealings, their tops couple together through high-voltage tube 30, and high-voltage tube 30 is provided with one first safety check 31 and one second safety check 32.The airintake direction of this first safety check 31 is for being set to vertical air inlet; The airintake direction of this second safety check 32 is for being set to horizontal air inlet.

Above-mentioned plenum chamber 10 has water intake 11 in its half the lower end, position, and inside, upper end is provided with piston 12, and an end of this piston 12 is enclosed in longitudinally in the high-voltage tube 30, and the connecting rod of piston 12 connects the floating plate 13 in the plenum chamber 10.Wave enters in the plenum chamber 10 from water intake 11, and the water column face rising pressurized air in the plenum chamber 10 is directly arranged to drive chamber through air outlet 14.In addition, water column is towards last promotion piston 12 pressurized air, and the effect through first safety check 31, can only advance, and can not go out.Through the rising and the sinking effect of wave, extruding air flow high-voltage tube 30 directions realize inflation.One takes turns after the wave, and piston 12 falls naturally, and the piston that safety check 31 is fallen in the time of the whereabouts attracts to open pore through vacuum action and sucks air, can only advance, and can not go out; And because the effect that wave decline floating plate 13 descends thereupon, plenum chamber 10 sucks air through air outlet 14, prepares the next round stroke; Take turns under the effect of wave repeat function exhausting air and promotion piston 12 pressurized air again second.

The top of air chamber 20 is provided with a pressure maintaining valve 21; Buoyancy aid 50 (its shape can be square or spherical) that can have neutral buoyancy of lower end installing of plenum chamber 10 and air chamber 20; The bottom connects a weight as ballast carrier 60; Make the semi-underground wave water column energy storage apparatus of present embodiment can stand directly in water, thereby to various harsh weather such as Anti-Typhoon.The top of plenum chamber 10 and air chamber 20 is provided with a bottom and first safety check 31, second safety check 32, and the engine-driving chamber 40 that is communicated with of pressure maintaining valve 21.The pressure maintaining valve 21 and first safety check 31 can be discharged gas through this generator drive chamber 40, drive generator blade and generate electricity.

The effect experimental example

When this device is implemented, only need this device be put into water, because action of gravity, can be upright voluntarily straight, this performance is the most critical way with antagonism high wind weather, and has adopted the design of offshore, can significantly reduce the infringement of physical environment to this device; This device can be produced the product of different size according to the wave spoke degree of wave; It is the 100cm diameter that buoyancy aid is adopted in this experiment; It is 200cm that plenum chamber and air chamber are 50cm diameter height; Piston in the plenum chamber is 5cm with outlet that is connected air chamber and connecting tube diameter, and the outlet diameter of air chamber discharging is that 5cm is 20 metre per second (m/s)s through modulating valve delivery air flow velocity.This experiment is implemented on the sea near 20 ° 54 ' 14.34 of north latitude ", east longitude 110 ° 37 ' 21.90 ", get early, in singly fill in (noon), late three time periods and the experiment parameter singly put following:

Time	Wave high (difference)	The wave distance	Wind-force	Inflationtime	Period of exhaust (20 meters seconds)
						7:00	1 meter	3 meters/3 seconds	2 grades	Be full of in 12 minutes	2.8 minute
12:00	0.5 rice	2 meters/3 seconds	2 grades	Be full of in 16 minutes	2.8 minute
