The efficient and energy-saving water turbine demonstration device has the total height of 16 cm, and the cylindrical water storage bin is arranged between the trough and a water wheel, so that a relatively big fall is formed, and the power pushing the water wheel to rotate is large; and the water storage bin is 9 cm in diameter, and a water turbine adopts a worm gear structure and acts continually under the gravitational potential energy of water, so that the water utilization ratio is improved.
Description
Technical field
In compulsory education curricular standard laboratory textbooks middle school " physics " and primary school's " science " experimental teaching, all useful hydraulic turbine model probes into the experiment of hydraulic turbine principle of work, how understand the hydraulic turbine utilizes the potential energy of water to do work, impulse water turbine energy conversion drives electrical power generators, belongs to middle and primary schools' natural sciences experiment teaching instrument.
Background technology
Hydraulic turbine model that experiment guiding in teaching material and instrument room configure in early days design very not science, diameter too large (15 ㎝), highly but very little (6 ㎝) of tank, water level low head is little, water wheels revolution is few, least reasonably adopt blade wheel structure, the diameter large (6 ㎝) of impeller, the water of full water groove is only over regard to stream for 10 seconds, the revolution rotated is few, firm water wheels have stopped operating once starting, and student does not also have enough time to see clearly, and water wheels are just motionless; The utilization factor of water is low, does once experiment and will waste a lot of water, and be exactly that sleeve pipe is inserted unstable in addition, design also bad, too little, rolling bearing and driving wheel also will be installed in upper end, cause upper part always to be played pendulum.In order to using water wisely, I have invented the hydraulic turbine of a worm-gear type structure, just can turn a lot of circle with the water of a small amount of (500ml), the time continuing to rotate is long, and be conducive to probing into of student, effect is very good.Test with one glass of water, water wheels function turns more than 40 turn, and student sees be stupefied.
Summary of the invention
The energy-efficient hydraulic turbine demonstration device of the present invention, relating to a kind of potential energy converting and energy is the energy conversion experiment teaching aid rotated, learning aid, belong to middle and primary schools' natural sciences experiment teaching instrument, comprise base, water storehouse, tank, driving wheel, turntable bearing, supporting sleeve, transmission shaft, the parts such as guiding gutter and worm gear, it is characterized in that: the base of truncated cone-shaped is connected with the cylindrical water storehouse mode patching groove, water storehouse upper end is provided with cylinder tank, tank size just in time can pack into cylindrical water storehouse top, multiple drainage hole is had around bottom of gullet, tank center is provided with supporting sleeve, supporting sleeve upper end is turntable bearing, driving wheel is just located on turntable bearing, guiding gutter is provided with bottom water storehouse, guiding gutter center is provided with cylindrical water delivering orifice, worm gear is located at water delivering orifice center, worm gear is connected with driving wheel transmission shaft, energy-efficient hydraulic turbine demonstration device overall height is 16 ㎝, is provided with cylindrical water storehouse between tank and water wheels, and the drop of formation is comparatively large, and the power promoting water wheels rotation is large, the diameter of water storehouse is set to 9 ㎝, and the hydraulic turbine adopts worm gear arrangement mode, and the gravitional force being subject to water continues acting, substantially increases the utilization factor of water.Beneficial effect: recycle one glass of water 500ml, allow the hydraulic turbine turn and do not stop.
Accompanying drawing explanation
Accompanying drawing 1 is energy-efficient hydraulic turbine demonstration device schematic diagram.By sequence number: 1. base, 2. water storehouse, 3. tank, 4. driving wheel, 5. turntable bearing, 6. supporting sleeve, 7. drainage hole, 8. transmission shaft, 9. guiding gutter, 10. worm gear, 11. patch groove.Accompanying drawing 2 is on teaching material and the J2168 hydraulic turbine model figure of instrument room's configuration.What water wheels adopted is impeller, and tank diameter large height small drop is little again, and sleeve pipe is little and high, patches tight, and during experiment, the rolling bearing on top, driving wheel play pendulum.Be followed successively by by sequence number: 1. tank, 2. guiding gutter, 3. sleeve pipe, 4. transmission shaft, 5. rolling bearing, 6. power wheel, 7. impeller, 8. rubber stopper, 9. leg, sequence number is the numbering of original product, has nothing to do with figure number of the present invention.
