[detailed description of the invention]
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely retouched
State, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the present invention
In embodiment, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise,
Broadly fall into the scope of protection of the invention.
Unless otherwise defined, the technology people of all of technology used herein and scientific terminology and the technical field belonging to the present invention
The implication that member is generally understood that is identical.The term used the most in the description of the invention is intended merely to describe concrete enforcement
The purpose of example, it is not intended that in limiting the present invention.Term as used herein " and/or " include one or more relevant institute
Arbitrary and all of combination of list of items.
As it is shown in figure 1, a kind of energy transformation demonstration apparatus for education experiment, including support 2, alcolhol burner 1, boiler 3,
Impeller 12 and syringe needle 9.
Described alcolhol burner 1 is placed on support 2.Boiler 3 is fixed on support 2 and is positioned at the top of alcolhol burner 1, is used for housing
Liquid.Center bottom boiler 3 is through offers the through hole passed through for described alcolhol burner 1 flame.It is additionally provided with on boiler 3
Chimney 5, one end of described chimney 5 is connected to through hole, and boiler 3 is also stretched out in the top of the other end once through boiler 3 of chimney 5
Outward, for discharging fume and observing the flame location of alcolhol burner 1, such as flame whether aligned through holes, to improve heat absorption efficiency.At this
In embodiment, the liquid held in boiler 3 is water.Heating transverse tube 4 it is provided with, at alcolhol burner 1 in described boiler 3
The lower heating boiler 3 of effect in water time improve the heat absorption efficiency of water, shorten the boiling time of water, thus by boiler 3
Water is converted to water vapour.Water filling port 7 and escape pipe 6 it is interval with on boiler 3.Wherein, water filling port 7 can allow for operator
Member adds water in boiler 3.The water vapour that escape pipe 6 is formed after the water boiling in boiler of feeding 3 flows out.Escape pipe 6
It is connected with one end of a wireway 8.One end away from escape pipe 6 of described wireway 8 connects syringe needle 9.Work as pot
After water boiling in stove 3, then water filling port 7 is sealed, make the steam in boiler 3 flow out to syringe needle from escape pipe 6
9, and spray from syringe needle 9.In the present embodiment, wireway 8 is preferably sebific duct.When syringe needle 9 is blocked, lead
Air pressure in tracheae 8 increases.Owing to wireway 8 is sebific duct, therefore, the air pressure increase in wireway 8 can cause wireway 8
Expand and then wireway 8 is slipped from the junction with escape pipe 6.Even if wireway 8 not yet slips from escape pipe 6,
Wireway 8, also due to its internal air pressure is high and expand and heave, allows experimenter find the pressure abnormity in device, opens in time
Water filling port 6 exhaust decompression, prevents boiler 3 too high and damage due to air pressure.
The energy transformation demonstration apparatus of the present invention also includes a support bar 11 and holder 10, and holder 10 is by support bar 11
It is connected with support 2, is used for clamping syringe needle 9 and makes it fix.Impeller 12 is installed on support 2 by a bracing frame 13,
And it is located at below syringe needle 9 so that it is can rotate under the drive of the high-pressure water vapor of syringe needle 9 injection, it is achieved
Interior can to machinery transformation of energy.
In the manufacturing process of the present invention, it is contemplated that the service life of equipment, boiler 3 uses fine copper to make, and makes boiler 3 not rapid wear
Bad, security is higher.Boiler 3 uses copper sheet cutting to be welded, and owing to full wafer copper sheet area is big, thermal conductivity good, therefore exists
During welding, even if directly using, powerful electric iron is the most difficult makes scolding tin melt very well, thus copper sheet is smoothed out welding.
In the present invention, for welding copper sheet smoothly, first junction, copper sheet edge is polished, upper solder(ing) paste；Then, utilize greatly
The tin that power electric iron last layer is very thin, stings the bending linking of copper sheet junction tightly the most again；The most again with alcolhol burner 1 to linking
Place's heating, is inserted simultaneously into tin bar note tin, now notices that tin must be enough, makes weld seam full, and otherwise boiler 3 easily leaks gas.
Heating transverse tube 4 in the middle of boiler 3 uses discarded radio antenna to cut and forms (material of discarded radio antenna is simple brass),
Reach the effect of waste reclamation.Must use when boiler 3 is punched and heat transverse tube and there is the drill bit punching of same diameter,
Till otherwise hole is difficult to solder to time excessive, and two polishing of heating transverse tube must be polished to see brass color, otherwise go up tin
The bad boiler 3 that also results in leaks gas.Impeller 12 and support 2 then form for aluminium sheet cutting, and the rotation of impeller 12 is little more like one
The rotation of waterwheel, this also allows student be easier to understand the operation principle of impeller 12.
During use, lighting alcolhol burner 1, the chemical energy in alcolhol burner 1 is converted into the heat energy of flame；The flame of alcolhol burner 1 is to pot
Stove 3 heats, it is achieved heat transmits；High-pressure steam in boiler 3 passes through escape pipe 6 through wireway 8 from syringe needle 9
Ejection, and then promote impeller 12 to rotate, this process is interior to be converted into mechanical energy (kinetic energy), it is achieved thereby that what energy converted
Demonstration.
Described above is the detailed description for the preferable possible embodiments of the present invention, but embodiment is not limited to the special of the present invention
Profit application range, the equal change completed under the technical spirit suggested by all present invention or modification change, the present invention all should be belonged to
Contained the scope of the claims.
