Technical field
The present invention relates to a kind of sea-anchor, especially relate to a kind of marine tidal-current energy that can utilize and carry out the sea-anchor generated electricity.
Background technology
At present, sea-anchor used on ocean fishing vessel is all generally common sea-anchor, better in the effect making boats and ships carry out in offshore anchoring.In use, due to the effect of ocean current, residing briny environment more or less all possesses the condition of marine tidal-current energy generating to sea-anchor, but conventional sea-anchor could not realize, to the utilization of the marine tidal-current energy resource that sea is enriched, not possessing the function utilizing ocean energy resources to generate electricity.
Simultaneously, nowadays the application of boats and ships to marine tidal-current energy adopts the method for directly installing tidal current energy generating equipment on the quarter more, although this kind of mode also can realize the utilization to marine tidal-current energy, but the additional power generation device of boats and ships afterbody may have influence on the normal operation of fishing boat, reduce ship deck working space, certain influence is produced to boats and ships normal operation.
The present invention utilizes sea-anchor to the convergence effect of ocean current, tidal current energy generating equipment is arranged on bottom sea-anchor, the high speed ocean current converged flows through the running of tidal current energy generating equipment drive electrical generators, realizes the combination that sea-anchor and marine tidal-current energy generate electricity, supplements the electricity consumption on ship.
Summary of the invention
Technical matters to be solved by this invention is to provide and a kind ofly marine marine tidal-current energy resource can be utilized to carry out the sea-anchor of the band tidal current energy generating equipment of marine tidal-current energy generating when anchoring, thus utilizes marine abundant marine tidal-current energy resource, supplements electricity consumption on ship.
The technical solution used in the present invention is: a kind of sea-anchor with tidal current generator, comprise anchor body, connection anchor body drags guiding principle, float with hull and is connected the rope of anchor body and float, sea-anchor also comprises tidal generating set and cable, wherein anchor body front end with drag guiding principle and be connected, anchor body tail end center is provided with tidal current energy generating equipment, float is connected with anchor body by rope, and tidal current energy generating equipment is connected with cable, and its electricity sent passes through cable transmission.When the operation of boats and ships stagnation of movement, anchor body drops in seawater, controls anchor body and stablizes and certain sea level altitude, anchor body is in metastable briny environment by float.Seawater can be converged to anchor body tail end by the conflux effect of anchor body, and the ocean current of convergence, by tidal current energy generating equipment, drives tidal current energy generating equipment work, the electricity that tidal current energy generating equipment sends by cable transmission on ship.
Further, tidal generating set comprises impeller and directly drives electrical generator, wherein directly drives electrical generator and is arranged on anchor body tail end center, impeller with directly drive electrical generator and be connected.The marine tidal-current energy generator of direct-drive type need not utilize gear case to carry out variable-speed processing, and more traditional marine tidal-current energy generator is more easy, and the startup of electrical generator requires low, has the generating efficiency higher than conventional generator.
Impeller is for can adopt horizontal axial type impeller.Wherein horizontal axial type impeller can be windmill type impeller or hollow through-flow impeller as required.The axle of impeller is parallel with water (flow) direction, and its blade extends radially from rotating shaft in impeller disk.Blade can be designed to again fixed pitch or feather formula blade as required.Also can further the blade declination angle of horizontal axial type impeller be designed to adjustable.
In addition, impeller can also adopt perpendicular axis type impeller.Perpendicular axis type impeller has simplicity of design, do not need to commutate, noise is little, the effective cross sectional area that can make full use of Tidal channels and trend kinetic energy, advantage that generating efficiency is high.
Perpendicular axis type impeller can be H type impeller, and its blade cross section is linear pattern; In addition, perpendicular axis type impeller is S type impeller, and its blade cross section is spiral line type.
Drag guiding principle to be made up of polyethylene stereotyped writing Knitted rope.Polyethylene stereotyped writing Knitted rope is fishing high-performance polyethylene monofilament by basis material, nominal diameter 10mm-14mm, and it has, and softness, intensity are high, good toughness, easy to operate advantage.
In sum, relative to prior art, main body of the present invention is sea-anchor, and sea-anchor in the seawater can converge the ocean current by it, and the swiftly flowing ocean current of gathering will drive marine tidal-current energy generator to operate, and realizes marine tidal-current energy generating, supplements electricity consumption on ship; Further, marine tidal-current energy generator of the present invention can adopt direct-drive type marine tidal-current energy generator, and relative conventional Load Flow energy electrical generator eliminates gear case, better with the matching degree of sea-anchor, and generating efficiency also wants high relatively, marine tidal-current energy can be utilized to send more electric.
Accompanying drawing explanation
Plan sketch when Fig. 1 is specific embodiment of the invention work;
Fig. 2 is sea-anchor cutaway view of the present invention.
Detailed description of the invention
Specific embodiment one as shown in Figures 1 and 2, comprise anchor body 1, connect draging guiding principle 6, float 5 and being connected the rope 4 of anchor body 1 and float 5, tidal generating set and cable 7 of anchor body and hull, wherein anchor body 1 front end with drag guiding principle 6 and be connected, anchor body tail end center is provided with tidal current energy generating equipment, float 5 is connected with anchor body 1 by rope 4, tidal current energy generating equipment is connected with cable 7, and its electricity sent is transferred on ship by cable 7.
