In the utility model, because the installation of band blade guiding wind wheel, natural wind to any direction, size, can both form the best angle of attack to the main air wheel, the lift maximum of its generation, the wind energy utilization height, blade is along the circle distribution of main air wheel, from distance of shaft centers from farthest, so just can produce very big moment with less wind-force, reach four liang and pull out very heavy effect, reduced the requirement to the strength and stiffness of blade, the utility model can combine wind energy and water, makes energy storage section and power generation part separate, needn't haggle over the rotating speed of wind wheel, but also stable electric generation.
The tangent line at blade tip place and the angle of this blade mid point and wind wheel spindle axis line are 45~60 ° in the described guiding wind wheel upper blade, the tangent line of the blade end points on the described main air wheel and this end points are 25~40 ° to the line angle of wind wheel spindle axis, make the wind of any direction can both produce the best angle of attack, form maximum lift.
The pipe that described hollow pillar stand links to each other with the blade water pump is provided with wind wheel series flow control valve and safety check.The setting of wind wheel series flow control valve can change the rotating speed of wind wheel or wind wheel is stopped operating, convenient for maintaining; The setting of safety check prevents that pump falls after rise to the water in the hollow pillar stand in the pond.
The water outlet of described hydraulic turbine generator is communicated with the pond, makes the water energy recycling, does not cause waste.
In above-mentioned any one technological scheme, described pond also can be connected by outer siphunculus and external water source.Design proposal is in order not to be subjected to the restriction of geographical environment like this.
[description of drawings]
Further describe each relevant details of the utility model embodiment below more in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional view of the utility model Fig. 1 along A-A.
[embodiment]
As Fig. 1, shown in Figure 2, the utility model includes main air wheel 12, hydraulic turbine generator 9, wind wheel main shaft 3 and pond 17, on the main air wheel 12 blade 15 is arranged circumferentially, the tangent line of blade 15 end points on the described main air wheel 12 and this end points are 25~40 ° to the line angle in wind wheel main shaft 3 axle center, certainly the line of its tangent line and wind wheel spindle axis at grade, through overtesting, its angle is arranged to 30 ° and is best angle, described main air wheel 12 is installed on the wind wheel main shaft 3, the guiding wind wheel 1 of band blade 14 is installed outside main air wheel 12, the tangent line at blade tip place and the angle of this blade 14 mid points and wind wheel main shaft 3 axial connecting lines are 45~60 ° in described guiding wind wheel 1 upper blade 14, in like manner, also in same plane, through overtesting, its best angle is 50 ° for its tangent line and line; Guiding wind wheel 1 is installed in by column 11 on the ground in pond 17, and this column 11 is a hollow tube, both can be used as supporting effect, but double as water pipe again, be provided with wet pit 13 above main air wheel 12, this wet pit 13 also can utilize the rainy day retaining, to replenish the deficiency of wind energy, in theory, what this wet pit 13 was provided with certainly is high more, and the potential energy of water is just big more, but in practice, main reference power consumption and geographical environment are selected reasonably height.Be provided with blade water pump 7 in the lower end of wind wheel main shaft 3, this blade water pump 7 is immersed in the pond 17, wet pit 13 links to each other with blade water pump 7 through pipe 16 by a hollow pillar stand, make water pump 7 can by hollow pillar stand with water pump in wet pit 13, and wet pit 13 links to each other with the water intake of hydraulic turbine generator 9 by another hollow pillar stand, and the water in the wet pit 13 just can make hydraulic turbine generator 9 generatings by hollow pillar stand.On pipe 16, be provided with wind wheel series flow control valve 4 and safety check 5, the setting of this wind wheel series flow control valve 4, mainly be that main air wheel 12 is slowed down or brakes, when series flow control valve 4 cuts out, the casing of blade water pump 7 is equivalent to an enclosed areas, it has utilized the incompressibility of water, just can regulate main air 12 speed of rotating of taking turns; In the utility model, the water outlet of hydraulic turbine generator 9 also is communicated with pond 17, make sent out the electricity water can be recycling; Pond 17 in the utility model can be connected by outer siphunculus 6 and external water source, make it not be subjected to the restriction of geographical environment, certainly under good geographical environment, promptly in the place that water is arranged, can directly build the utility model in this place, directly the water source that will locate is as pond 17, and this and an above-mentioned autocratic pond are equivalent.The utility model at first is converted to wind energy the potential energy of water, potential energy converting and energy with water is an electric energy again, as long as the main air wet pit of taking turns 12 upper ends has water like this, the height of its wet pit 13 is certain, thereby its potential energy converting and energy becomes electric energy also just highly stable, so just can stable electric generation.The utility model is almost holistic iron structure, and the basis is very big, support post more than 11 and firm.The blade 14 of guiding wind wheel 1 is made very narrow, very little to the resistance of wind, 12 on main air wheel is subjected to moment loading, and needn't worry the attack of violent storm.System of the present utility model can be designed to it large-scale building, below main air wheel 12, a head cover plate 2 is installed, overhead locate to build up two-layer building at head cover plate 2, its first layer can be made generating operation, other remaining spaces can be made factory building, and the second layer can be used as house or warehouse, greatly utilizes its space.So some enterprise when design house, can take native system into account simultaneously, reaches the saving cost, effectively utilizes the purpose of wind energy.The of the present utility model design successfully particularly to the very practicality of medium and small electricity consumption enterprise, played good replenishing to the area of special short of electricity for it solves severe power shortage.
