Abstract

When water is used for pushing a hydraulic turbine for generating electricity, a blade of the hydraulic turbine is oblique. Thus, when the water impacts the blade, partial water pushes the blade to move, and the partial water works but the other water presses the blade and does not work. Thus, a water wasting phenomenon exists. Thus, the power is not high. Thus, the present invention uses a piston for replacing the blade. Because the water consumption of the piston is low, the water pressure is in a sealed container and vertically pushes the piston, no water is wasted, more than 90% of water can work, the power is increased but a small piston is required to be installed into a big piston. A pushing rod, a big gear, a small gear, etc., are required to be used for overcoming the forward and backward movement of the big piston for the requirements of overcoming the power loss and the engine rotating speed. The power can be increased by about 1.4 times in anticipation.

Description

Piston hydroelectric generator

Technical field

The present invention relates to a kind of piston hydroelectric generator.

Background technique

Water promotes water turbine (signal of figure 1) or impact generator (signal of figure 1) generating, (among the figure: 11 blades, 12 axle center, 3 generators, 13 supports), from analytically, their blade is a deflection, and water is the cant blade always, is not straight leaf-pushing plate, thrust is disperseed, and it is to promote blade rotation that part water is arranged, and has done merit, have partly that water is to be pressed on the axle center, by the axle center pressure transmission on support, do not play the acting effect, the phenomenon of wasting water is arranged, so power is not high.

Therefore just design with piston and replace blade, because of the water usage of piston is few, can save 1.57 times water, the pressure of water is again that vertical pushes away to piston in the container of sealing, and the water more than 95% can both be done work for a waste water, raising power.

Summary of the invention

The reason that improves power has 2 points:

1, piston can be saved 1.57 times in water: water promotes water turbine or the impact generator rotates a commentaries on classics, and drive generator rotation one forwarding electricity, because of they are that camber line rotates, water usage is the girth of circle, according to the circle girth with diameter ratio, can establish Ratio of the circumference of a circle to its diameter 3.14 and make ratio and calculate (as the signal of figure=1) water and promote piston and move back and forth once, and drive generator and rotate one and transmit electricity, because of it is a straight line motion, water usage is that diameter of a circle comes once, return once, the long 1+1=2 that establishes diameter calculates, and contrasts from water usage, with 3.14 ÷ (1+1)=1.57, that is to say that water wheels geometric ratio piston is wasted water 1.57 times more, is one of not high reason of water wheels and impact generator power, suppose to use instead the piston generating, as the signal of figure three, among the figure: 1 big piston, 2 small pistons, 3 generators, 4 push rods, 5 gearwheels, 6 small gears, 7 bent axles, the steamboat of 8 control water inlets and draining, 9 cylinders, 10 connecting rods.Figure three is straight line motions, can save 1.57 times water, and the water of saving is spent generating, and electricity that can multiple 1.57 times is removed loss, electricity that can multiple about 1.4 times, but want heavy, be easy to manufacturing.(also can alleviate) about heavy and friction.

About saving the analysis of 1.57 times in water, can be with the area of a circle of figure 21, fill two dotted lines (as the signal of figure 2 2) are shown water wheels etc. with the travel schedule of first water usage, be shown the water usage of piston with the travel schedule of second, in the size of calculating water usage and power character, can not calculate by with dashed lines, the line computation that will represent with arrow, it is the average lines of three lines, also be average water usage and stroke, just can be regarded as out water wheels etc. needs the water of 1 * 3.14=3.14, could pushing generator rotates one and transmits one times electricity, and piston only needs the length of diameter to go to equal 21 time 1, the water of 1 * 2=2, just but pushing generator rotates one and transmits one times electricity, and with 3.14 ÷ 2=1.57, this is the analysis that piston can be saved 1.57 times in water.

When design, if the area of first is 1 times, piston area should be 1.57 times, their water usage is (first: the water usage of 1 (area) * 3.14 (stroke)=3.14 about equally just, second: the water usage of 1.57 (area) * 2 (stroke)=3.14), different is: first has only 1 times powered generator to rotate a commentaries on classics, send out 1 times, second has 1.57 times power, pushing generator rotates one to be changeed, and sends out 1.57 times, so the difference that improves 1.57 times of power is just arranged, remove loss, electricity that can multiple about 1.4 times is one of reason that improves power.

2, cant is good not as what directly push away: because the blade of water wheels etc. is a deflection, water is the cant blade, it is to promote blade rotation that water about 75% is arranged, done merit, it is to be pressed on the blade that water about 25% is arranged, through the blade pressure transmission on the axle center, by the axle center pressure transmission on (on the ground) on the support so do not play the acting effect, effective power less than 1, have only about 0.75 times, it is the same with 100 jin of power cant automobiles to can be compared to us, because of thrust is disperseed, having partly, power is to push away automobile to advance, done merit, it is to push away automobile to swing to partially on one side that part power is arranged, and does not play the acting effect, 100 jin of power can only be worked as 75 jin of usefulness, if with 100 jin of power vertical push away automobile, do not disperse because of thrust, 100 jin of power can be worked as 100 jin of usefulness, be that therefore two (wherein the loss of water wheels wants big to not high former of water wheels icocline leaf-pushing plate power, the loss of impact is less), with the piston generating, water is in the container of sealing, vertical pushes away to piston, thrust is not disperseed, and 100 jin of power can be worked as 100 jin of usefulness, owing to do not waste the power about 25%, so just can improve about 1.2 times of power, be improve power former therefore two.

More than 2 be the advantage of piston, shortcoming is: piston is to move back and forth, it or not straight line motion, rotating speed is not high, be not adapted to the needs that generate electricity very much, because of the piston heaviness, doing when moving back and forth, halting when needing urgency, returning when anxious again retreats, can not pause a moment, because halting when needing urgency, returning when anxious again retreats, this will consume very big power and just can accomplish, it is the shortcoming of piston, it is the reason that people do not utilize the piston acting very much, about this shortcoming, improvement below available overcomes, promptly use a kind of piston hydroelectric generator, the two ends that it is included in seal container are provided with out, water inlet, big piston is slidably mounted in the described container, and small piston is located at the centre of big piston and can axially slides between the scope of big piston two ends along big piston, and the thickness of small piston is less than the thickness of big piston, after water promotion big piston slides into the top of described seal container one end, big piston is motionless, and small piston continues to slide into the top of described seal container one end under the promotion of water, then, after water promotion big piston slides into the top of the described seal container the other end round about, big piston is motionless, and small piston continues to slide into the top of the described seal container the other end under the promotion of water, and so forth, small piston is connected with bent axle by push rod, bent axle drives gearwheel and rotates, and gearwheel drives the pinion rotation that is engaged with, and small gear drives generator for electricity generation.

Embodiment

Improve one, small piston need be installed: be called big piston and small piston respectively in piston, small piston certain distance that can in big piston, move back and forth, now cylinder is divided into ten equal portions, signal as figure four each figure, when doing each time stroke, capable about 0.85 the stroke of big piston (8.5 equal portions), water usage is 0.85, all the other strokes of about 0.15 (1.5 equal portions) are continued to have gone by small piston, 0.85+0.15=1, one stroke also just is over, refer now to big, the big piston of the process that small piston moves back and forth: figure three drives small piston and walks to 8.5 equal portions, just stopped advancing, signal as figure 41, replace it to continue to walk to 10 equal portions by small piston, become the signal of figure 42, upright anxious the returning of small piston retreats, and walks to the place of 9.5 equal portions, signal as figure 43, water has entered and has promoted the big piston return motion, and catch up with small piston, drives the acting of small piston return movement, become figure 44 from figure 43, by the time big piston walks to 1.5 equal portions, has stopped motion again, as figure 45, replace it to continue to walk to 0 equal portions by small piston, as the signal of figure 46, returning by 0 equal portions, walk to 0.05 equal portions, as figure 47, water has entered the reversion of promotion big piston and has caught up with small piston, drives small piston to 10 equal portions motion acting, has become the signal of figure 41 again.The installation of small piston is the effect of playing reversion when replacing big piston to make urgency, big piston is the effect of playing acting, because of the area of small piston little, halt when anxious easily, returning when making urgency easily again retreats, small piston is in big piston, replace big piston to continue to have gone in this time of 0.15 stroke, halting when big piston just has a unnecessary time intercropping anxious, starting return motion when making urgency again, and catch up with small piston, drive the acting of small piston return movement, overcome the loss that big piston moves back and forth, change over and be equivalent to straight line motion and improve power.

Improve two, need to install gearwheel and small gear: because of the piston generating that moves back and forth, rotating speed is not high, it is another shortcoming of piston, this shortcoming can be utilized that the large gear turn the small gear and rotate, and with slow rotation, the principle that changes over quick rotation overcomes, do not reduce and do not influence power, if design with all facilities of existing water turbine, that just enlarges the area and the stroke of piston, and also available two pistons replace water wheels one better.(wherein: an acting, another reversion that does homework, such to internal-combustion engine, an acting, three do homework), consume with the as many water of water wheels, slower number of times and that move back and forth is less though piston moves back and forth, but the area of piston and stroke have increased, lifting surface area also is increased, and power is also along with increase, and area multiplies each other with stroke, if increase 6 times, the number of teeth of gearwheel is exactly 6 times of the small gear number of teeth, just can utilize that the large gear turn the small gear and rotate and improve rotating speed, just can overcome the not high shortcoming of rotating speed, reach the needs on the generator speed, as the signal of figure three, change push rod or bent axle in any case, perhaps the length of gearwheel and small gear etc., need increase or shorten by it, as long as can keep the number of teeth of gearwheel is 6 times of the small gear number of teeth, big piston moves back and forth once, and generator just can rotate 6 to be changeed, sending out 6 times electricity, is can not influence power to reduce.

Improve three, need to install push rod: because of the installation of push rod is in order to increase the stroke of piston, to reduce the number of times that piston moves back and forth; Again can the speed that move back and forth is more slack-off, just can overcome greatly and had little time the loss of return motion, just be again to install, the raising on the interests power is arranged, the needs that help designing in order to be adapted to drive the needs that bent axle rotates.

Other difficulty, heaviness as piston, the collision that large and small piston moves back and forth (available block rubber overcomes), the move back and forth requirement of number of times of piston, requirement on the generator speed, the generation of piston inertia power (flywheel can be installed on small gear, just can produce inertial force of a size such as water wheels and do work).The control of water inlet and draining and requirement etc. all can overcome, and are applicable to medium and small water power plant, large-scale power station, and available piston set is fine.
