Description

A kind of novel tidal current energy water turbine blade construction
Technical field
The present invention relates to marine tidal-current energy technical field of power generation, particularly relate to a kind of novel tidal current energy water turbine blade construction.
Background technology
Trend mainly refers to the regular seawater stream produced with tidal phenomena, and trend changes its size and direction twice daily. Marine tidal-current energy is different from tide, tide is the seawater lifting that flood tide and ebb cause, trend is the tangential movement of seawater, energy entrained by tide is potential energy, the modes such as reservoir impoundment power generation of building a dam can be adopted to be used, and marine tidal-current energy generating is then directly utilize the mechanisms such as tidewater water impact blade to drive generator work to generate electricity.
Compared with conventional energy resources, marine tidal-current energy has the following advantages: cleaning renewable; Energy total reserves is big; Change regular measurable; Do not need to block Hai Jianba, and generating set usually all submergence is in the seawater, less on marine organisms impact, environment can not be produced three-waste pollution, also not exist and common in conventional hydropower construction take the problem such as farmland, resettlement of affected residents.
Owing to possessing above-mentioned advantage, the exploitation of marine tidal-current energy is by pay attention to day by day. Marine tidal-current energy resource is the important supplement of future source of energy, particularly significant in the power supply solving island. The capacitation efficiency of current marine tidal-current energy generator group is lower, and the advantage of Z-axis power generation assembly is all to generate electricity when direction of tide is contrary, has certain advantage. This project partly covers the efficiency that vertical-axis tide energy generating set can effectively improve marine tidal-current energy generator group, it is to increase the utilization ratio of marine tidal-current energy, promote the exploitation of marine tidal-current energy this kind of new forms of energy.
The defect of marine tidal-current energy generator group conventional at present is: adopt common Z-axis water turbine, time trend flow direction is perpendicular to water turbine axis, will there be the time of half in the blades turning direction of water turbine and to carry out flow path direction contrary, flows the rotation hindering water turbine on the contrary. If water turbine design conditions are for rotating clockwise, when turbine blade forwards left side to, sense of rotation will be contrary in trend flow direction, hinder the rotation of water turbine, reduce its capacitation efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of wing flap type Z-axis turbine blade and improves trend to the forward impact of turbine blade, thus improves marine tidal-current energy utilization ratio.
Above-mentioned technical problem can be solved by following technique means: a kind of novel tidal current energy water turbine blade construction, comprise blade and wing flap, blade is angularly radial to be fixed on propeller hub, the centre of propeller hub is provided with the main shaft being fixed in water turbine main body, it is characterized in that: the outer rim of blade is provided with the axle sleeve of protrusion, the position matched with axle sleeve on wing flap is provided with recessed notch, the outer rim having notch on wing flap is provided with axis hole, and by passing, axle sleeve is connected blade with the wing flap pivot of axis hole with wing flap.This kind of mode of connection is similar to the connection structure of hinge, it is possible to make connection more effectively with closely.
Blade and wing flap are slab construction. Slab construction can effectively increase the area receiving current, it is to increase energy conversion efficiency.
Blade is furnished with and the horizontal stiffener of main shaft axis perpendicular. Stiffening web is for increasing the intensity of blade, it is to increase the working life of blade.
Horizontal stiffener hydraulic turbine main shaft extends to blade body leaf tip part.
Horizontal stiffener quantity on every sheet blade is 3-5 bar.
The height on the long limit of blade construction is 4-6 times of its short limit, and blade has 3-6.
Being connected with sun wheel on main shaft, wing flap pivot is provided with sun and planet gear, and sun and planet gear is meshed with sun wheel. Drive planetary gear rotation when sun wheel rotates, thus drive wing flap relative to blades turning, change the angle between wing flap and blade. This kind of wing flap angle regulative mode is similar to the principle of gear type hap-type rudder, improves trend to the forward impact of turbine blade by the adjustment of angle, it is to increase capacity usage ratio.
The usefulness of the present invention is: compared with prior art, different and other turbine blades are limited by the single situation of flow path direction, novel tidal current energy water turbine blade construction, the angle with primary blades can be changed along with the direction flowed and flow velocity, active adjustment can also be carried out by Controlling System, improve trend to the forward impact of turbine blade, thus improve capacitation efficiency.

Embodiment
As shown in Figures 1 and 2 to wing flap formula Z-axis turbine blade structure, comprise blade 1 and the wing flap 2 of plate-like structure, blade 1 has 5, the height on the long limit of blade construction is 4-6 times of its short limit, angularly radial it is fixed on propeller hub, the centre of propeller hub is provided with the main shaft 4 being fixed in water turbine main body, the outer rim of blade 1 is provided with the axle sleeve of protrusion, the position matched with axle sleeve on wing flap 2 is provided with recessed notch, the outer rim having notch on wing flap is provided with axis hole, and by passing, axle sleeve is connected blade 1 with the wing flap pivot 3 of axis hole with wing flap 2. This kind of mode of connection is similar to the connection structure of hinge, it is possible to make connection more effectively with closely.
Blade 1 is furnished with the horizontal stiffener 11 with main shaft axis perpendicular. Horizontal stiffener quantity on every sheet blade is 3-5 bar. Horizontal stiffener 11 extends to blade body leaf tip part near hydraulic turbine main shaft.
Being connected with sun wheel on main shaft 4, wing flap pivot 3 is provided with sun and planet gear, and sun and planet gear is meshed with sun wheel. Drive planetary gear rotation when sun wheel rotates, thus drive wing flap relative to blades turning, change the angle between wing flap 2 and blade 1. This kind of wing flap angle regulative mode is similar to the principle of gear type hap-type rudder, improves trend to the forward impact of turbine blade by the adjustment of angle, it is to increase capacity usage ratio.
Above embodiment is for understanding the present invention's, it it is not limitation of the present invention, about the those of ordinary skill in field, on the basis of technical scheme described in claim, multiple change or modification can also be made, such as, on the blade of the present invention setting of stiffening web, it is also possible to be 3,5 or 6 rows; The wing flap partial-length of the blade and blade tip can also be 5 times or 4 times of width, and these changes or modification should be understood to still belong to protection scope of the present invention.
