Abstract

A turbine using a pair of caterpillar belts features that said caterpillar belts are connected by multiple transvers chain axles at intervals, each axle has one blade able to move on it, and the lower end of each blade is connected via two ropes or chains to preceding transvers axle, so form a stable right triangle structure. When water stream impacts the blades, the baldes drive caterpiller belts. It can be used to generate electricity by low-speed water stream, sea wave, wind flow and tide flow with high utilization rate of energy (90% or more).

Description

Single crawler type turbine

The present invention relates to a kind of waterpower and wind turbine, especially can increase the lifting surface area of impeller, make to be subjected to force direction vertical, do not change the direction of current.Simple in structure, can reduce resistance.The utilization ratio of current homenergic is improved.Can be used in the high low speed water of river, river, sea, midocean, the single crawler type crawler belt turbine of wave, morning and evening tides, distinguished and admirable motion generating.

Present known water turbine, wind turbine.Because all be round, blade on every side all is the inclined-plane bending, and it is moving to immobilize.So their force direction that is subjected to all is an off plumb.So, all lower to the utilization ratio of power.Moreover their length of blade is limited, does not also utilize when too many at strong current and distinguished and admirable impulse force, and they have utilized with regard to again the time.So wasted a lot of energy.Moreover their resistances in the current of low speed are very big, so the utilization ratio of useful work is lower.Present water turbine must change the direction of current at work, and water turbine is effectively worked.And the power of change current is to the kinetic energy and the potential energy that just must reduce water.So, also wasted a lot of energy.Moreover the hydraulic turbine structure more complicated of other type that has also increases accordingly as in a lot of resistances.

The present invention provides a kind of single crawler type crawler belt turbine, and its vane stress direction is vertical, and does not change the direction of current.So, all bigger to current and distinguished and admirable capacity usage ratio.Because it has adopted flap, so, reduced current and distinguished and admirable in certain resistance in moving.Because it has adopted the below impeller folk prescription of the impeller in the crawler belt stressed.So, as long as there is water movement will promote its motion.A lot of utilizable hydraulic power potentialss have so just been increased.Particularly the crawler belt of single crawler type turbine is long.Long, weak point according to circumstances can increase and can subtract, so, bigger to current and distinguished and admirable energy utilization ratio.It can also the current of low speed and distinguished and admirable in motion, and to the utilization ratio of low speed water than high the manying and can utilize the generating of turning round of ocean current, morning and evening tides, wave of the water turbine in modern times.Its effect in this respect is about 2 to 5 times of modern water turbine approximately.Because it is simple in structure, thus the energy that is consumed at the volley than other turbine lack, so, relatively will be greatly to the utilization ratio of current energy.

The object of the present invention is achieved like this: it is made up of one pair of crawler belt.Former and later two wheel shafts of this pair crawler belt are separately fixed at the place ahead and the rear of fixing frame by front and back.And maintain a certain distance.And the two ends of each wheel shaft and the bearing of body frame all are with bearing.The bearing inboard of each all has a gear and axle fixing.The number of teeth diameter of these four gears all equates or becomes certain ratio, and all corresponding.Two pairs of chains are enclosed within the left side of this forward and backward axle respectively, on the right gear.On these two pairs of chains, all there are a plurality of equidistant hard axles connecting sidewards respectively, and maintain a certain distance.On these cross chain axles, be with a blade respectively.There are rope about two or slide fastener etc. connect in the lower end of these blades.The other end of rope or slide fastener etc. is connected with axle in front of the axle that these blades are overlapped.The length of rope or chain link etc. be make these blades reach vertical about just.At this moment the upper end of blade is subjected to the fixing of the hard axle of cross chain, is restricted or chain link etc. fixing in the lower end, and the cross chain axle that the blade upper end is overlapped is subjected to fixing of both sides chain again with the cross chain axle that the other end was connected of rope of its front or slide fastener etc.Like this, blade, rope or chain link etc., chain three parts have just formed a leg-of-mutton rock-steady structure.When current etc. from positive (one side that rope is arranged) by the time, blade will be subjected to the impact of current etc., and drives caterpillar drive.And blade is to keep the vertical left right motion.When these blade movements arrive the back end, just begin to move upward.At this moment blade just loses the resistance (stressed motion) to water gradually.Just stretch across in the time of above moving to and travel forward on the top of crawler belt.So just reduced current and distinguished and admirable impact resistance, thereby reduced the resistance to motion of water turbine top blade.When running to the front end, just be subjected to the power of turning over that moves downward of taking turns previously, and the gravity of the power of passing through of being moved and the earth and the lower end falls, and fall into current or distinguished and admirable, at this moment just be subjected to current or distinguished and admirable impulse force again and drive caterpillar drive.So their one and another cycle of motion has just been finished in circulation.The integral body of general this pair crawler belt is dried up slightly place in current all.Vertical endways blade is at underwater exercise below having only.

Owing to taked such scheme, can make the modern water turbine and the available power of wind turbine improve about about 0.5 to 1 times.And can finish present water turbine and can not turn round in low speed water and ocean current, wave, morning and evening tides, or the power of running is low can not generate electricity or phenomenon that generated energy is few.The power of single crawler type water turbine in this respect, it is 2 to 5 times of left sides of modern water turbine.It is simpler than the manufacturing of other water turbine, and power consumption is few, thereby has also increased a lot of useful work.It will make huge contribution for the generating cause in the China and the world.
