Description

Two buoyancy aids-ratchet-type wave energy generating set

The utility model relates to a kind of wave energy generating set.

Domestic and international existing wave energy generating set is broadly divided into pneumatic type, the formula of surging and reservoir formula three classes, all need basically to use complex structure, expensive turbo machine, thereby increased the complete machine cost, and it is very big to implement difficulty.

The purpose of this utility model is exactly in order to address the above problem, and a kind of two buoyancy aids-ratchet-type wave energy generating set of simple in structure, cheap, easy enforcement is provided.

Technical solution of the present utility model:

A kind of pair of buoyancy aid-ratchet-type wave energy generating set is characterized in that it is made up of Wave energy collecting device and conversion equipment two-part.Wave energy collecting device is made up of two buoyancy aids that adopt hinge to be connected, and a root post all is installed on each buoyancy aid separately, and wherein the top employing activity of the root post form of propping up is connected with an end of a two-sided tooth bar; Top at another root post is equipped with conversion equipment, and two-sided tooth bar passes conversion equipment, and two flank of tooth up and down of this two-sided tooth bar are meshed with the flank of tooth of two reverse ratchets on the conversion equipment respectively.Conversion equipment is made up of two rotating shafts, two reverse ratchets, pair of sprocket group, pair of engaged gears group, a generator and several bearing supports, a ratchet and a sprocket wheel are installed respectively in the every rotating shaft, wherein in a rotating shaft gearwheel is installed also, is installed in the rotating shaft of generator with this gearwheel pinion in mesh.

That the utility model adopts is inexhaustible, nexhaustible, cleaning, pollution-free, reproducible wave energy be as the energy, utilize between two buoyancy aids fluctuation because of wave to produce relative tilt and collect wave energy, adopt two reverse ratchets and pair of sprocket group again, to-and-fro motion converted to rotatablely move, and then the drive generator sends electric power, be a kind of wave energy generating set of simple in structure, cheap, easy enforcement, and do not take any soil.Huge wave energy is being contained in immense sea.China is an ocean big country, and available wave energy is very abundant.The formula of the wave energy on the unit width is: P ≈ H ²T (kilowatt/meter).In the formula: H is wave height (rice); T is wave period (second).If 3 meters of wave height, in 7 seconds cycles, so, the wave energy that wave had that strides across 1 meter sea just has: P ≈ 3 ²* 7 * 1=63 kilowatt, the wave energy that wave had that strides across 1 km sea just has 6.3 ten thousand kilowatts.Huge energy like this, that abandons is unfortunately tangible, promotes the well-being of mankind with it!

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A of conversion equipment among Fig. 1 is to enlarged view.

As shown in Figure 1, 2, the utility model is made up of Wave energy collecting device and conversion equipment two-part.Wave energy collecting device is made up of buoyancy aid 1 and buoyancy aid 7, adopts hinge 3 to be connected between buoyancy aid 1 and the buoyancy aid 7, and a root post 2 is installed on the buoyancy aid 1, and the form of propping up in the employing activity of the top of column 2 is connected with an end of a two-sided tooth bar 4; One root post 6 also is installed on buoyancy aid 7, on the top of column 6 conversion equipment 5 is installed, two-sided tooth bar 4 passes conversion equipment 5, and two flank of tooth up and down of two-sided tooth bar 4 respectively with conversion equipment 5 on the ratchet 9 and the flank of tooth of ratchet 14 be meshed (seeing Fig. 2 for details).Conversion equipment is made up of two rotating

shafts

8 and 15, two

reverse ratchets

9 and 14, pair of sprocket group 10, pair of engaged gears group 13, generator 12 and several bearing supports 11, ratchet 9 and sprocket wheel 10 are installed in the rotating shaft 8, a ratchet 14 and sprocket wheel 10 are installed in the rotating shaft 15, a gearwheel 13 also is installed, is meshed with small gear on being installed in generator 12 rotating shafts.Ratchet 9 and ratchet 14 are two ratchets of installing by opposite direction, mechanical energy transmission between rotating shaft 8 and the rotating shaft 15 realizes by chain wheel set 10, and the mechanical energy transmission between the rotating shaft of rotating shaft 15 and generator 12 realizes by gear train 13, gear train 13 is rotating speeds required according to the rotating speed of rotating shaft 15 and generator 12, and the power that needs to transmit designs.Rotating shaft 8 is respectively to be supported by several bearing supports 11 with rotating shaft 15.

During the utility model work, with anchor system whole device is positioned on certain sea earlier.Buoyancy aid 1 and buoyancy aid 7 are successively arranged along the wave propagation direction, and are connected with hinge 3.When the crest of wave and trough successively pass through buoyancy aid 1 and buoyancy aid 7, certainly lead to relative tilt between buoyancy aid 1 and the buoyancy aid 7, and drive column 2 and the relative swing of column 6 generations, it is reciprocating that column 2 will drive two-sided tooth bar 4, because ratchet 9 and ratchet 14 are installed by opposite direction, so when two-sided tooth bar 4 gets out the paper motion, the ratchet skid of ratchet 14, and ratchet 9 work, and clockwise direction (setting) rotation is done in drive rotating shaft 8, by chain wheel set 10, drive rotating shaft 15 and also do the clockwise direction rotation; When two-sided tooth bar 4 pierces the paper motion, the ratchet skid of ratchet 9, and ratchet 14 work, and the clockwise direction rotation is also done in drive rotating shaft 15.Like this, regardless of the reciprocating direction of two-sided tooth bar 4, can both utilize ratchet 9 and ratchet 14 and chain wheel set 10, in rotating shaft 15, convert rotatablely moving of identical sense of rotation dexterously to, by pair of engaged gears group 13, drive generator 12 and send electric power again.
