Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the perspective view of the embodiment of the present invention.
Fig. 2 is the side direction perspective structure schematic diagram of the embodiment of the present invention.
Marginal data: 11 first fixed heads; 12 second fixed heads; 13 connecting rods; 14 the 3rd fixed heads; 2 cylinders; 3 sealed valves; 4 pistons; 5 piston rods; 6 slide plates; 7 snubber assemblys.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
As shown in Figure 1, 2, the hydrogen detonation demonstrator of the present embodiment comprises that fixed support and two ends are located at the cylinder 2 on described fixed support, in the present embodiment, fixed support comprises the first fixed head 11 and the second fixed head 12, the first fixed head 11 is connected by connecting rod 13 with the second fixed head 12, and the second fixed head 12 is also connected with the 3rd fixed head 14 by connecting rod 13.
One end of cylinder 2 is provided with sealed valve 3, is provided with piston 4 in cylinder 2, and piston 4 can be in the interior to-and-fro movement of cylinder 2, and piston 4 is connected with piston rod 5, and piston rod 5 is connected with slide plate 6 through the other end of cylinder 2.Slide plate 6 is provided with the through hole passing for connecting rod 13, thereby connecting rod 13 becomes the slide rail of slide plate 6, thereby slide plate 6 can be slided along route.In cylinder 2, be connected with lighter.For the impact of buffering slide plate 6, the 3rd fixed head 14 is provided with snubber assembly 7, and in the present embodiment, snubber assembly 7 preferably adopts spring.
When experiment, open sealed valve 3, and piston 4 is adjusted to pre-position, with a certain amount of air that prestores, this precalculated position can calculate according to the diameter of cylinder 2, experiment requisite oxygen tolerance and content of oxygen in air.Inject the hydrogen of scheduled volume, and close sealed valve 3, after hydrogen fully mixes with oxygen, utilize piezoelectrics electric discharge, the blast of igniting of the mixed gas of hydrogen and oxygen, volumetric expansion, piston 4 is released fast, because slide plate 6 is enclosed within on connecting rod 13, therefore piston 4 and slide plate 6 are limited to move along connecting rod 13, and the motion path of blast is fixed, experiment safety is reliable, in the time that slide plate 6 is promoted to approach the 3rd fixed head 14 fast, due to the existence of snubber assembly 7, slide plate 6 also can not cause shock to the 3rd fixed head 14.
The present invention also can realize different experiment purposes by the proportioning, the regulation experiment step that change gas.
1, synthetic water experiment
Open sealed valve 3, and piston 4 is adjusted to the contained amount of oxygen of air in cylinder 2 is 25ml place, using syringe is 50ml hydrogen from 3 points of three total injections of sealed valve, after each injection, after gas fully mixes, light gas, can be observed the interior water droplet that occurs of cylinder 2, for increasing experiment effect, also can in cylinder 2, add paper of cobalt chloride,test.
2, the temperature of research hydrogen-oxygen explosion time
Open sealed valve 3, and piston 4 is adjusted to the contained amount of oxygen of air in cylinder 2 is 5ml place, record initial temperature, on fixed support, paste blank sheet of paper, and on slide plate, fix a recording pointer, at the interior injection of cylinder 2 10ml hydrogen and close sealed valve 3, after fully mixing, lights gas, measure and record the notes length on blank sheet of paper, calculate the expanding volume of gas, thereby calculate blast temperature.
3, mist experiment processed
After hydrogen detonation experiment, in cylinder 2, generate water droplet, close sealed valve 3, and pull piston 4, in cylinder 2, will there is mist.
Compared with prior device, the present invention is simple in structure, easy to carry, explode controlled, use more safe and reliablely, conventional efficient is high, and can realize different experiment purposes by the proportioning, the regulation experiment step that change gas, and increase experiment interesting, greatly improve experiment teaching effect.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited in above-mentioned embodiment, and every technical scheme that belongs to the principle of the invention all belongs to protection scope of the present invention.For a person skilled in the art, some improvements and modifications of carrying out under the prerequisite that does not depart from principle of the present invention, these improvements and modifications also should be considered as protection scope of the present invention.
