Embodiment
The present invention is by utilizing physical construction to control and simulating nature phenomenon--the process of atmospheric water circulation, with this, show the application of mechanical mechanism in actual production and in controlling.
As shown in Figure 1, the present invention is mainly comprised of atomization system, kinematic train, control system, Special Effect System four major parts, demonstrates respectively to being responsible for the processes such as raining in atmospheric water cyclic process, vaporization.
As shown in Figure 2, atomization system is mainly partly comprised of fan 1, storage mist storehouse 2, logical mist pipe 3, lower pipe 4, atomizer 5, pond 6 etc., the mobile power that provides of fog is provided its fan 1, by the effect of fan 1, the fog being produced can be picked up enter into 2 li, storage mist storehouse in pond by atomizer 5.And fog is blown into 3 li of logical mist pipes, on logical mist pipe 3, every 4mm, being equipped with diameter is that the aperture of 2mm facilitates fog therefrom to flow out to form water smoke curtain, reach the simulate effect of cloud and mist.The atomizer being installed in pond adopts 24V voltage to power, and after energising, visible pond Zhong Shui changes into water smoke.The additional top cover in pond forms confined space, and when atomizer 5 does not stop production after unboiled water mist, its fog will flow in storage mist storehouse by lower pipe, be blown into air fog is brought in logical mist pipe 3 by fan 1.Because fan is installed on outside, avoided it to contact with the direct of water smoke, guaranteed that it can not make moist and break down because of water smoke.
Fig. 3 is kinematic train of the present invention, and it utilizes three grades of straight-tooth to slow down, and motor speed is dropped to desired value and its rotation is passed on partial gear.Wherein transmission shaft 7 is connected with the partial gear on front panel, by power transmission to front end Special Effect System.Three grades of straight-tooth reducer casinges of transmission adopted, greatly reduce the whole space of taking up an area of reducer casing, and input is 100:1 with output ratio of gear, has reduced initial motor speed, has improved output torque.9 is mechanical switch gear, controls the power-up period of whole system.By the triple reduction gear output gear 8 being installed on transmission shaft 7, be meshed with switch gear 9, its ratio of gear is 1:1.Drive its rotation to realize the mechanical power supply control function of whole system.10 for motor output shaft its be connected with motor, setting motor be N20 micromachine.For convenience of native system, use, its three grades of reducer casinges, every grade of design ratio of gear is 1:5; 1:4; 1:5.Its module need to choose 1 according to design, and minimum tooth tooth number is 12.
As shown in Figure 4, Figure 5 and Figure 6, Special Effect System in the present invention is mainly responsible for realizing the realization of the actions such as the precipitation of invention system and lightning sound, and it is mainly comprised of tooth bar 11, partial gear 12, slip tank 13, track 14, LED lamp 15, sound equipment 16, rain pipe 17, water pump 18.By kinematic train, drive partial gear 12 to rotate, by transmission of power to tooth bar 11.Tooth bar 11 adopts and is rigidly connected with slip tank 13, and the tank 13 that makes to slide can be followed tooth bar and be moved back and forth in track, when water pump pumps into water, enters rainy pipeline, flows in tank.The precipitation hole seeing through on tank is dripped, and realizes mobile rainfall simulation process, represents utilization and the effect of indexing mechanism.It is 2mm that its rainfall hole adopts diameter, is divided between the upper and lower 4mm, is divided between left and right totally 3 row of 4mm, and the hole array of 10 row forms, and has realized evenly falling of rainwater, and between partial gear 12 and tooth bar 11, ratio of gear is 1:2.Its partial gear 12 adopts half toothing, modulus is 1, tooth bar 11 adopts upper and lower bidentate structure, has realized gear one direction and has rotated 1 circle, and tooth bar moves back and forth, its principle of work as shown in Figure 5, neutral gear is in clockwise rotating, and when its incomplete tooth goes to top with upper gear rack engagement, due to gear, second half does not have tooth, make it separated with lower gear rack, and then drive whole tooth bar to move right.When incomplete tooth goes to below with lower gear rack engagement, owing to not having the part of tooth to go to top, on gear, tooth is separated with tooth bar top.And beginning and the engagement of below tooth bar, and then band carry-over bar turns left.Finally realize moving back and forth of tooth bar.
In Fig. 4,15 is LED bulb, the demonstration of simulation thunder and lightning, and 16 is small-sized MP3 sound equipment, plays the thunder of simulation.Meanwhile in rainfall groove rainfall by water pump from pond by the rain pipe of water suction total system top, by slotting in rain pipe, make water to stay and to flow in the middle of rainfall groove along it, for guaranteeing that water does not outflow, it is initial point that its rainwater tube seat be take its horizontal mounting center, to both sides fluting 50mm, guarantee that current can normally flow in the middle of tank respectively.
As shown in Figure 7, in the present invention, control system adopts mechanical switch gear to control, by slotting in gear, plated with copper in groove, it can be conducted electricity, 3 sections of three circumferential grooves in brushes difference corresponding gear are installed on support 23, the input positive pole of system power supply is connected with gear centre, by buried copper sheet, it can be passed in gear grooved.By rack-mount brush, on gear, scan, when brush touches the copper sheet on its circumference, its corresponding system will be connected with input power, and it can be worked, and by being calculated as, guarantee that whole system loops work according to set.In figure, 20 is rainfall switches conductive groove, and 21 is lightning switches conductive groove, and 22 is thunder switches conductive groove, the straight conductive trough of three conductive troughs of 24Wei UNICOM.Circular arc degree on above-mentioned three sections of conductive trough circumference closes and is respectively rainfall switches conductive groove 280-330 degree, 21 lightning switches conductive groove 160-210 degree, 22 thunder switches conductive groove 60-90 degree, adopt this mechanical rotary switch, rotation in conjunction with motor, realized preferably rainfall, thunder, lightning switch duration and control constantly, made simulate effect true to nature, and deepened the understanding of student to mechanical gear switch.
The present invention adopts traditional mechanical model teaching is incorporated in atmospheric water circulation presentation process, make course intuitively abundant, be beneficial to running through of knowledge point, classroom, and deepened student the mechanical component such as indexing mechanism have been had to darker understanding, there is higher using value.
