Description

Electric heating ability of swimming mirage wonder analog demonstrator

(1) technical field:

The utility model relates to light continuous analog demonstrator of refraction and total reflection in medium, is specially a kind of electric heating ability of swimming mirage wonder analog demonstrator, is applicable to the demonstration to mirage wonder phenomenon.

(2) background technology:

The device of current domestic and international water analogue mirage wonder all is to inject half clear water in tank, again salt (or sucrose) is put into clear water, stir with glass bar, make it be dissolved into nearly state of saturation, on its liquid level, put salt (or sucrose) solution of a thin plastic below covering again, on film, slowly inject clear water, up to the water of tank near till full.After a while, film is extracted out from groove one side gently, and at this moment, clear water and salt (or sucrose) aqueous solution interface is clearly demarcated, approximately need after 6 hours, because diffusion disappears the interface, has formed a diffusion layer at intersection, liquid refractive index reduces from bottom to top gradually, produce a density gradient, this moment, liquid dosage was finished, and illuminated the outdoor scene thing then, observed the mirage view of simulation at scenery opposite side tank window.

There is following problem in this mirage wonder analogue means:

1, experimental implementation complexity, setup time is long, needs multi agent cooperation.

2, a large amount of salt (or sucrose) solution of each groove domestic demand preparation, and after spreading evenly, not can be recycled, the waste of time and resource caused.

3, going up clam picture, following clam picture and material object can not occur simultaneously.

(3) utility model content:

In order to address the above problem, the utility model provides a kind of electric heating ability of swimming mirage wonder analog demonstrator, and the density gradient that changes water with easy method distributes, and allows the demonstration of analogue mirage wonder become easy easily.

Can realize the electric heating ability of swimming mirage wonder analog demonstrator of above-mentioned purpose, comprise casing, be provided with tank in the casing, offer picture window on the casing of tank one side, can see the screw clamp opposite side from picture window, be provided with the scenery district in the casing of described tank opposite side, the scenery district is illuminated by shot-light, refraction and reflection for demonstration light, also be provided with laser instrument in bottom, scenery district, also offer two watch windows on the casing of view direction one side, can observe the situation in tank zone and scenery district respectively by these two watch windows, what the utility model was different with other mirage analog demonstrator is to be provided with electric heater unit in tank, and this electric heater unit is heating rod or horizontal heating plate that several levels are evenly arranged, the setting height(from bottom) of heating rod or heating plate is the middle and upper part of water depth in the tank.

Heating rod or heating plate are installed on the middle and upper part of water depth in the tank, be used for evenly adding in the horizontal direction the water of hot water storgae middle and upper part, the little top that floats over of density owing to hot water, make formation temperature gradient (density gradient) down waterborne in the tank, the refractive index difference of each gradient layer provides condition for the light from the reflection of scenery district produces refraction by tank.Reach 25 ℃ even when higher when heating makes the temperature difference of top and the bottom water, observe scenery in the opposite side scenery district from picture window, mirage has just occurred.

For effectively controlling top and the bottom water temperature difference in the tank, one temperature controller is installed is controlled the duty of heating rod or heating plate, temperature controller is provided with the temperature of selecting the temperature difference and sets button, the state display screen that shows the temperature difference and the temp probe that flexibly connects, temp probe stretches into the middle and upper part of water depth in the tank, when the temperature difference reaches the initial value that sets, the automatic powered-down of temperature controller.

The employed laser instrument of the utility model is homemade laser pen, and laser pen is installed in by adjusting knob on the vertical moving groove of laser pen tressel, and laser pen can height up and down, can also regulate the angle of inclination with surface level.

Advantage of the present utility model:

1, experiment is shortened setup time greatly, and operation only needs a people.

2, the water in the tank can be recycled, and economizes on resources, and reduces expenses.

3, going up clam picture, following clam picture and material object can occur simultaneously.

4, can demonstrate refraction, total reflection light path with laser.

5, temperature controller has the measuring water temperature function, the effect of playing safeguard protection and saving the energy.
