Description
Technical field
The present invention relates to the blade and its manufacture method of a kind of trunnion axis energy by ocean current generator, the blade is suitable for high-power
Trunnion axis energy by ocean current generator use.
Background technology
Energy by ocean current is a kind of clean reproducible energy, and China's energy by ocean current rich reserves, its developing and utilizingpotentiality is huge.Relatively
For wave, the change of energy by ocean current is steady and regular, big with energy density, regular strong, the advantages of reserves are big.Ocean current
Energy by ocean current is converted into electric energy by energy generator, and for users to use, blade, as the first order mechanism for capturing energy of ocean current, is ocean current
The important component of energy generator, its structure design, material selection directly affects energy capture efficiency, and can unit steady for a long time
Fixed operation.
The study hotspot in current energy by ocean current field is concentrated mainly on following aspect:(1) Hydrodynamic design of ocean current machine blade
Method；(2) design of the adjustable spacing mechanism of blade；(3) design studies with supporting way are installed；(4) blade cavitation erosion research and
Suppress；(5) research of unit layout；(6) design of ocean current energy generator new ideas.
For the blade of small-power trunnion axis energy by ocean current generator, blade dimensions are smaller, can directly use multi-shaft interlocked machine
Bed is integrally machined, and for the blade of higher power levels axle energy by ocean current generator, blade dimensions are more long, it is impossible to using multi-shaft interlocked
Lathe is integrally machined.The blade of existing relatively high power trunnion axis energy by ocean current generator, some uses and traditional trunnion axis wind
The similar blade of power generator blade, its method of manufacturing technology is integrally as traditional horizontal shaft wind-driven generator vane
With glass steel making, glass fibre reinforced plastic tensile elastic modelling quantity is 19.71GPa, and elastic modelling quantity is relatively low, 10 times poorer than steel, due to sea
The density of water is more than 1,000 times of air, therefore the load impacting that is subject to of blade of energy by ocean current generator is big, and this blade is in sea
Easily there is serious blade in stream energy use to wave and runout problem, or even bending or situation about fractureing occur；
Some use bronze materials or stainless steel or alloy steel making blade, blade are solid, and weight is big, and
And, because the blade of high-power energy by ocean current generator is more long, the blade of bronze material has that self-strength is not enough, and
And, blade overall processing also is carried out without sufficiently large lathe, manual grinding can only be carried out, manual grinding is taken a lot of work very much, and essence
Degree is inadequate, and own wt is very big, and cost is also very high.
The marine site silt content of many ocean current energy abundances is high, for example Chinese Zhoushan offshore sea waters.Traditional wind-driven generator
Composite material blade case hardness is low, during blade movement, by grit impact, friction, easily produces indenture or scuffing.
In addition, tip segment rotating speed is fast in underwater environment, cavitation erosion is also easy to produce, causes tip segment to be more also easy to produce damage.
In addition, in the running environment of ocean, it is necessary in face of the problem that suspension fishing net is kinked, if energy by ocean current generating set is without certainly
Safeguard measure, is wound by fishing net, stuck by there is unit, it is impossible to run well, and even results in the situation that whole unit is damaged.This
Outward, different from atmospheric environment, ocean attachment is also the problem that must take into consideration, bacterium, algae, and the growth of biological larva etc. can be led
Blade accelerated corrosion is caused to damage.
The content of the invention
The present invention is directed to above-mentioned deficiency of the prior art, there is provided one kind can resist trend load impacting, high intensity, height
Rigidity, anti-grit impact friction, wear-resistant, blade tip cavitation, the winding of anti-fishing net, the higher power levels axle of anti-marine organisms attachment

(7) the blade surface spraying antifouling coating manufactured in step (6), to prevent marine organisms from adhering to, individual blade manufacture
Finish.
7. the manufacture method of the blade of higher power levels axle energy by ocean current generator as claimed in claim 6, it is characterised in that：Institute
State metal crossbeam use cross section forType orThe metal crossbeam of type,Type andThe metal crossbeam of type
Stretch out rib side to both sides, can increase blade rotate when warping rigidity and bending stiffness, and then improve blade run when reverse,
The problem bend, waved,Connecting plate is fixed between the lateral surface and medial surface of type metal crossbeam, metal can be increased
The rigidity of crossbeam.
8. the manufacture method of the blade of higher power levels axle energy by ocean current generator as claimed in claims 6 or 7, its feature exists
In：The outer rim of the leading edge metal bag piece smoothly transits with the outer rim of exterior skin and inside panel and is connected, and the connection that smoothly transits is favourable

9. the manufacture method of the blade of higher power levels axle energy by ocean current generator as claimed in claim 8, it is characterised in that：Institute
State the length of the length of the second net-cutter more than the first net-cutter, the edge tilted of the first net-cutter and the second net-cutter is set,
The afterbody of the first net-cutter is type wide, and stress is improved with the contact area of metal blade tip to increase, and the afterbody of the second net-cutter is
Type wide, stress is improved to increase the contact area for filling out core with foam.
10. the manufacture method of the blade of higher power levels axle energy by ocean current generator as claimed in claim 9, it is characterised in that：
If metal blade tip and the welding of the first net-cutter, the welding position of metal blade tip and the first net-cutter by sanding and polishing treatment with
Reduce current drag and increase attractive in appearance.
