Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, wave maker of the present utility model comprises push pedal 2 on the density stratification tank 1,, push pedal once 3, two sets of transmission mechanism 4 and a control terminal 5.Upper and lower push pedal 2,3 is arranged on tank 1 certain transversal section, and upper and lower push pedal 2,3 and tank 1 are wide, the upper and lower height that pushes away 2,3 plates is identical with the height of LAYER FLUID in the tank 1 respectively, upper and lowerly pushes away the height of 2,3 plates and the height of LAYER FLUID can be regulated according to the experiment needs.Two sets of transmission mechanism 4 connect upper and lower push pedal 2,3 respectively, and by control terminal 5 controls.Control terminal 5 changes the kind of drive of gear train 4 by adjusting input parameter, thereby drives upper and lower push pedal 2,3 with separately the reverse tangential movement of speed, acceleration and stroke.
In the foregoing description, every sets of transmission mechanism 4 comprises two slide rails 41, four belt pulleys 42, a driving belt 43 and motors 44.Wherein, two slide rails 41 are horizontally set on respectively on the limit wall of tank 1 both sides; Four belt pulleys 42 surround rectangle, and wherein three belt pulleys 42 are fixed on the limit wall of tank 1 one sides, and another belt pulley 42 is connected with the output shaft of motor 44; Driving belt 43 is connected with last push pedal 2 or following push pedal 3, and driving belt 43 is walked around four belt pulleys 42 successively; Motor 44 is fixed on the limit wall of tank 1, and is connected with control terminal 5.In addition, upper and lower push pedal 2,3 both sides all are equipped with pulley, and upper and lower push pedal 2,3 can be slided along slide rail 41.When motor 44 starts, drive driving belt 43 operations, the upper and lower push pedal 2,3 that links to each other with driving belt 43 will be done tangential movement along slide rail 41.
In the foregoing description, for guaranteeing to make the stability of upper and lower push pedal 2,3 in the wave process, install cross-brace 6 respectively additional in a side of upper and lower push pedal 2,3.
Specifically describe interior solitary wave of the present utility model below and make wave method.
In tank 1, successively inject two kinds of fluids that density is different, and make pycnocline be positioned at place, upper and lower push pedal 2,3 separatrix.As shown in Figure 2, when ripple is made in enforcement, control terminal 5 drives upper and lower push pedal 2,3 oppositely tangential movement simultaneously by gear train 4, makes the LAYER FLUID in the tank 1 produce reversed flow, thereby produce epirelief or recessed interior solitary wave on the LAYER FLUID layering interfaces.For guaranteeing the mass balance in the tank 1, the movement velocity of upper and lower push pedal 2,3 has following relation:
