Embodiment
Referring to drawings and Examples the utility model is described in detail.
Fig. 1 is the perspective view of steam engine model of the present utility model.As shown in Figure 1, steam engine model of the present utility model comprises base 1 and the bracing frame 2 that is arranged on the base, by the flywheel 13 of bracing frame 2 supports and the cylinder 4 of built-in piston.Be provided with fuel chambers 5 and boiler 14 on the base 1, be formed with opening on fuel chambers 5 sidewalls, be placed with the fuel cassette 6 of contain fuel in the fuel chambers 5.Fuel chambers 5 supports the boiler place and is circular shape, and fuel chambers is placed opening top, fuel cassette place and is circular-arc.After the use, fuel cassette 6 can be from fuel chambers 5 interior taking-ups, and fuel cassette 6 tops are covered by lid 7.
Cylinder can arrange one, is communicated with exhaust manifolds, also can arrange two, and namely flywheel 13 both sides are respectively arranged with a cylinder, the first cylinder 4 and the second cylinder 12.Two cylinders are communicated with snorkel 11 and exhaust manifolds 10 internal communication by snorkel 11.Two cylinders are separately fixed on the back up pad that is connected to bracing frame 2 upper ends.The connecting rod that is connected with piston of upper end passes bottom cylinder, and the lower end is connected with crank axle on the crank that is arranged on bracing frame 2 bottoms.Crank is patty, and crank axle is arranged on the non-circle centre position of crank, or the proximal edge place, and the crank axle of two cranks has 90 ° phase differential.The circle centre position of crank is provided with the flywheel shaft that the other end is connected to middle flywheel center, bracing frame bottom.
Flywheel shaft runs through flywheel, bracing frame and two cranks; One end of flywheel shaft is connected to the circle centre position of crank, and the other end is connected to the circle centre position of flywheel, and the axis hole that forms on the bracing frame is passed in the centre.Flywheel shaft is supported by bracing frame 2, and can rotate freely in the axis hole of bracing frame 2, and plays the effect of connection and support flying wheel and crank.Like this, when connecting rod moved up and down with piston rod, crank will rotate under the drive of connecting rod, thus the flywheel driven rotation.
Steam engine model of the present utility model adopts external and the transparent structure of boiler, allows the student can clearly observe the course of action of steam engine.During test, water is injected in the boiler 10 from water filling port 9, the fuel cassette 6 that fuel is housed removes lid 7, puts into fuel chambers 5, lights.After the water boiling in boiler, have steam and enter cylinder through exhaust manifolds 10 and snorkel 11.Piston in the cylinder is up and down under the effect of steam, and steam flows between the first cylinder and the second cylinder under the effect of piston, and two pistons are alternately moved up and down.The connecting rod that connects with piston can move up and down along with piston, because the lower end of connecting rod is connected on the crank axle that is arranged on the non-circle centre position of crank, under the drive of connecting rod, crank axle can drive the crank rotation.The rotation of crank is delivered to flywheel by flywheel shaft, and flywheel shaft is positioned at the circle centre position of flywheel, and flywheel driven rotates.Unnecessary steam is discharged boiler through exhausr port 8.
Above-mentioned process is clearly demonstrated out, and steam enters cylinder from steam boiler through exhaust manifolds and submarine snorkel, and the piston in the cylinder is reciprocating from end to end in order under the vapor pressure effect.Steam makes ceaselessly to-and-fro movement of piston, and piston makes the course of work of flywheel rotation by connecting rod, crank.
In sum, steam engine model of the present utility model, can realize the perfection demonstration to steam engine principle of work and duty, all drive mechanisms all carry out external, boiler has carried out transparent processing, the student can be observed intuitively, realize the generation of steam and the process that steam rotates by the cylinder flywheel driven, make student's easy to understand and the principle of work of accepting steam engine, and can motivate students' interest in learning, inspire student's imagination and creative thinking, be conducive to teen-age intelligence development; And in experimentation, the student can take action on one's own to participate in, and reaches the effect of interactive teaching and learning, and the visual field that also can widen student's kinematics of machinery aspect helps the cultivation of students'comprehensive ability.
