Description
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.
Background technology
Trend is primarily referred to as the regular sea water stream produced with tidal phenomena, and trend changes its size and Orientation twice daily. Marine tidal-current energy is different from tide, tide is flood tide and the sea water lifting caused of ebbing tide, trend is the horizontal movement of sea water, energy entrained by tide is potential energy, the modes such as generating that construct a dam to store water can be adopted to be used, and marine tidal-current energy generating is then directly utilize the machinery drive electrical generators work such as tidewater water impact impeller to generate electricity.
Compared with conventional energy resource, marine tidal-current energy has the advantage that cleaning is renewable; Energy gross reserves is big; Change regular measurable; Hai Jianba need not be blocked, and generating set is generally immersed in sea water, marine organisms impact is less, environment will not be produced three-waste pollution, what to be also absent from conventional hydropower construction common takies the problem such as farmland, immigration allocation.
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 energy supply solving island. The capacitation of current marine tidal-current energy generator group is inefficient, and the advantage of vertical axis TRT is in that all to generate electricity when direction of tide is contrary, has certain advantage. Partly covering vertical-axis tide energy generating set and can be effectively improved the efficiency of marine tidal-current energy generator group in this project, improves the utilization rate of marine tidal-current energy, promotes the exploitation of this new forms of energy of marine tidal-current energy.
Marine tidal-current energy generator group conventional at present has the disadvantage that: adopt common horizontal shaft water-turbine, trend flow direction be perpendicular to turbine shaft to time, the blade rotation direction of the hydraulic turbine is by opposite direction with incoming flow for the time having half, and incoming flow hinders the rotation of the hydraulic turbine on the contrary. If Design of Hydraulic Turbine operating mode is for rotating clockwise, when turbine blade forwards left side to, direction of rotation will be contrary in trend flow direction, hinder the rotation of the hydraulic turbine, reduce its capacitation efficiency.
Summary of the invention
The technical problem to be solved is to provide a kind of novel tidal current energy water turbine, and described horizontal shaft water-turbine adopts flap airfoil fan, and this blade can significantly improve the trend forward impact to turbine blade, thus improving marine tidal-current energy utilization rate.
Above-mentioned technical problem can be solved by following technological means: a kind of novel tidal current energy water turbine, and including propeller hub and the blade equiangularly arranged in propeller hub periphery, the top of blade is provided with wing flap, and wing flap is hinged by wing flap pivot and blade.
As decision design, the angle between wing flap and blade can regulate.
Blade and wing flap should all adopt slab construction.
The center of propeller hub is fixed with the main shaft of novel tidal current energy water turbine, and the quantity of blade is 3 to 6.
Being connected to central gear on main shaft, wing flap pivot is provided with planetary gear, and planetary gear is meshed with central gear. Driving planetary gear rotation when central gear rotates, thus driving wing flap relative to wheel rotation, changing the angle between wing flap and impeller. This wing flap angle regulative mode is similar to the principle of gear type flap-type rudder, improves the trend forward impact to turbine blade by the adjustment of angle, improves capacity usage ratio.
The invention have benefit that: compared with prior art, different and other hydraulic turbines are limited by the situation staying direction single, novel tidal current energy water turbine blade, the angle with primary blades can be changed along with the direction stayed and flow velocity, improve the trend forward impact to turbine blade, thus improving capacitation efficiency. The blade of novel tidal current energy water turbine is provided with horizontal stiffener, it is possible to increase the intensity of turbine blade.
Accompanying drawing explanation
Fig. 1 is wing flap formula horizontal shaft water-turbine blade top view;
Fig. 2 is wing flap formula horizontal shaft water-turbine blade axonometric chart.
Detailed description of the invention
Wing flap formula horizontal shaft water-turbine as shown in Figure 1, including propeller hub, the center of propeller hub is fixed with the main shaft 4 of novel tidal current energy water turbine, and equiangularly arranged in propeller hub periphery have 5 blades 1, the top of blade 1 is provided with wing flap 2, and wing flap is hinged by wing flap pivot 3 and blade 1. Blade 1 and wing flap 2 should all adopt slab construction. On every blade 1, level (being perpendicular to the axis direction of main shaft 4) is provided with 4 row's reinforcements 11, to improve the structural strength of blade.
Being connected to central gear on main shaft 4, wing flap pivot 3 is provided with planetary gear, and planetary gear is meshed with central gear. Central gear is respectively positioned on planetary gear the gear-box bottom the hydraulic turbine Nei and is driven by the driving mechanism being connected with gear-box. Driving planetary gear rotation when central gear rotates, thus driving wing flap relative to wheel rotation, changing the angle between wing flap and impeller. This wing flap angle regulative mode is similar to the principle of gear type flap-type rudder, improves the trend forward impact to turbine blade by the adjustment of angle, improves Energy harvesting.
Above example is for understanding the present invention's, it is not limitation of the present invention, those of ordinary skill about 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 reinforcement, it is also possible to be 3,5 or 6 rows; The flap portion length of blade blade tip can also be 5 times or 4 times of width, and these changes or modification should be understood to still fall within protection scope of the present invention.
