Description

Dragging type floating raft wave generating set

Technical field

The present invention is a kind of electricity generating device that the wave energy of seawater is converted into regulated power by mechanical device.Belong to ocean wave energy and utilize technical field.

Background technique

1992, the United Nations just classified wave-activated power generation as the first place of exploitation regenerable marine energy.According to measuring and calculating, in the wave length range of 1M, when wave height is 2M, when wave period was 6S, generated output was 24KW; When wave height is 3M, when wave period was 11S, generated output can reach 130KW.The wave height of ocean of China mostly is 2～5M greatly.

Up to now, whole world application wave power generation patent surpasses thousand, wherein has kind more than 20 to carry out sea trial, by following three types of belonging to basically of more employing:

(1) air energy---by wave energy being converted to the air flows energy, the generator for electricity generation of driven rotary is a kind of of extensive use the most.

(2) mechanical energy---with the wave stroke oscillator, oscillator pump oil form pressure oil, the rotation of oil pressure actuated motor drives generator for electricity generation.

(3) water potential---the impact by wave promotes seawater, allows the kinetic energy of seawater be converted into potential energy, again with the generating of hydraulic turbine generator low water level.

The long 130M of wave power equipment of Britain's ocean electric power transfer organizational construction, output power is 750KW, is prominent in the world wave power equipment at present.Japan latest model 130KW equipment, every 10MW ripple electricity cost is about 7.3～33.1 yen/KWH.

Under the standard of considering of pursuing high efficiency, low cost, durability, Security, above developing effect all is to allow the people well-content.

Summary of the invention

In view of the problem of above-mentioned existence, the present invention is a kind of electricity generating device that is adapted under most of wave environments wave energy being changed into lasting level and smooth power output.Can do large-scale generating field configuration and use, also can make the low power electricity generating device in island and use.Characteristics be simple in structure, install simple and easy, maintenance easily, size is suitable.

The present invention realizes by following measure: by two and plural light-duty buoyant raft, in 1/2 wave wavelength range, dispose, spur the gear train that is fixed on the sea bed or is suspended in grappling under water continuously by tow rope, and then drive the airtight waterproof generator for electricity generation that is connected on the same base.

Embodiment

Buoyant raft of the present invention is the detachable structure of framework (Fig. 3).By the ship shape raft head (9) that triangle or arc constituted, connect at the bottom of the connecting ring (12), raft body, raft of tow rope arranged side by side like the directed rudder fin of triangle (11) (Fig. 4), the louvre type squamous is caught and can (Fig. 5) be constituted by device (10).The raft body can be fastening with inflation buoyancy aid or expanded polystyrene filling.Before storm arrives, can take off raft and transport.

The louvre type squamous is caught can provide closed ability (Fig. 5 catches the reverse side of energy device for single louvre type squamous) by torsion spring (14) by device, regulate the suitable elastic force of torsion spring, make the squamous blade in trough, be in closed state at summit, when being in trough when crest moves, under the impact of wave, current are opened blade by the arc notch (13) of raft head position, under the promotion of push rod (17), all blades that connect together are later opened together, form the Ying Boqiang of continous way, can catch more kinetic energy.With like directed rudder fin (11) of triangle and arc three-support face (21), more can produce thrust forward.The length of suitable lengthening raft, the output of electric energy is more average.

For adapting to different waves, the present invention has designed the Gear combination device that is fit to than the shortwave wave of the long wave wave at deep-sea and offshore respectively.

As Fig. 1, for being fit to the electricity generating device designed than the wave of long wave.It by airtight waterproof generator (1), ball float (5),, the gear train of gearing shaft (3) and flywheel transmission shaft (4) combination, base (2), tow rope (7) and three or above light-duty buoyant raft (6) are formed, and are adapted at the waters that the depth of water surpasses 30M and work.Make the integral body of airtight waterproof generator and formations such as gear train, base be fixed in about 30M place under the sea (as can directly being fixed on the sea bed) less than 30M with anchor chain by levitation devices such as floating bed or ball floats, the upper end of tow rope is suspended in the sea with a ball float, by the sealed buoyant raft work of lock uint.Under the situation of long wave, three or above buoyant raft by the adjusting of directed rudder empennage angle, are Pin Zixing and stagger in 1/2 wave wavelength range.When a raft during at crest, a raft is at trough, other the neutral position at them (when raft is abundant, as long as can make the pulling force mean allocation, can place buoyant raft greater than 1/2 wave wavelength).One of tow rope links to each other with raft, and a cephalic disc is on the transmission shaft that flywheel is housed, and when the tow rope forward pulling, flywheel transmission shaft driven gear transmission shaft rotates, and gearing shaft drives generator and carries out work.When raft is in summit to the peak valley process, to run out of steam, at this moment be in the ball float that coils on the same flywheel transmission shaft, drive the counterrotating of flywheel transmission shaft at the buoyancy function float downward, tow rope is coiled in again on the flywheel transmission shaft and resets, the work of beginning next round.

Fig. 2 is for being applicable to 30M with headwater depth, the electricity generating device that use in the short shallow sea of wavelength.Essential structure is an airtight waterproof generator (1), a gearing shaft (3), two flywheel transmission shafts (4) and gets in touch two gear driven axles (8) formation that two flywheel transmission shafts are made move toward one another, be fixed on the sea bed with fixed base (2), constitute one group power plant by two buoyant raft pullings.Two buoyant rafts are staggered by directed rudder stable equilibrium, and the front and back branch is in crest and trough, and after a buoyant raft was in crest, power lost, and continue to provide power by another buoyant raft, and the buoyant raft that loses kinetic energy is resetted, and move in circles.The buoyant raft length sum of this design should be less than 1/2 wave wavelength.For obtaining the output of bigger power more stably, can organize buoyant raft more and share together power is provided.Every group of buoyant raft is in the 1/2 wave wavelength of oneself.
