Abstract

The utility model discloses a tornado experimental instrument and an experimental operation method of the tornado experimental instrument, wherein a circular hole with the diameter of 6-12mm is arranged in the center of each of two bottle caps; then two bottle caps are bound together back to back with glue; then more than half bottle of water is filled in one bottle; and the bound bottle caps are used to connect the two bottles together, the bottle caps are tightened, and the bottle with water is placed under the other bottle. The experimental operation method comprises the following steps: the two bottles are taken up with two hands to ensure that the bottle with water is above the other bottle, the two bottles are shaken rapidly with hands, the water in the upper bottle swirls rapidly under the shaking of hands and flows down to the low bottle through the circular holes in the centers of the bottle caps, and the shape of the central part of water is similar to the shape of tornado when the water is in a swirling and flowing-down process.

Description

The wind spout experiment instrument

Technical field:

The utility model relates to a kind of middle and primary schools physics, science teaching equipment, definite a kind of wind spout instrument of modeling test of saying so.

Background technology:

In the Nature, when the cold and heat air convection current, easily form the air-flow vortex, as when running into stronger cold and heat air, the air-flow vortex of formation also strengthens thereupon and strengthens, and mode of appearance differs, in the driving of wriggling rapidly, the center pressure of vortex is little like a giant dragon, but energy is bigger, can be involved in ground object in the air, its scene is grand in surprise.Yet the peculiar scene of this occurring in nature does not but have on the classroom of the physics that has teaching aid or instrument to be presented in middle and primary schools and education of science.

Summary of the invention:

Therefore there is great demand in people to the test teaching aid or the equipment of wind spout, up to now, do not find that also the inventor has finished the present invention finally through studying repeatedly and testing about relevant report of the present invention.

The purpose of this utility model just provides a kind of wind spout experiment instrument, simulates this spontaneous phenomenon of wind spout, reaches the teaching efficiency of visual pattern.

Scheme of the present utility model is by up and down two transparent bottles and bottle cap are formed, described bottle comprises transparent vial, beverage bottle and various plastic bottle, have the circular hole of diameter 6-12mm earlier at the middle part of two bottle caps, again with being bonded as one that carry on the back dorsad at the back side of two bottle caps with glue, more than half bottle water of packing in bottle therein then, with the bottle cap that glues two bottles are connected as one and bottle cap is tightened again, make the bottle of water be placed on the below earlier.

During experiment, both hands are picked up two bottles simultaneously and are inverted, and the bottle that makes water up and bottle is vertical, shake bottle rapidly with hand, the water in the bottle is rotated rapidly, stop subsequently shaking, bottle is placed on the desktop, at this moment can be observed, the water in the last square vase is in rotating downward bottle process of flowing, and the centre has just formed the air funnel shape, just like the downward diffluence of the state of wind spout, the image displaying wind spout attitude and imposing manner, when testing once more, but the repetitive operation said procedure.

The utility model has the advantages that and make simply that material is easily got, pilot demonstration is interesting strong, and visual in image, effect is obvious.

Be described in further detail below in conjunction with accompanying drawing.

Description of drawings:

Fig. 1 is two bonding synoptic diagram of bottle cap;

Fig. 2 is the utility model experimental state synoptic diagram.

Embodiment:

Upper bottle cover 1 shown in Fig. 1, the middle part of lower bottle cap 3 have the circular hole 2 of 6-12mm, and what carried on the back dorsad at the back side of upper bottle cover 1, lower bottle cap 3 sticks to one.

The bottle 4 of going up shown in Fig. 2 is connected as one by upper bottle cover 1 and lower bottle cap 3 with following bottle 5, in the last bottle 4 more than half bottle of water is housed.Water in the last bottle rotates under the shaking of both hands rapidly and by in following bottle of the inflow downwards of the circular hole in the bottle cap, in rotating the process that flows downward, the shape that its centre shows has just formed the form of similar wind spout.

Claims

1. wind spout experiment instrument is made up of two transparent bottles and bottle cap up and down, and it is characterized in that: the described bottle (4) of going up is connected as one by upper bottle cover (1) and lower bottle cap (3) with following bottle (5), in last bottle (4) more than half bottle of water is housed.

2. wind spout experiment instrument according to claim 1 is characterized in that: described upper bottle cover (1), the middle part of lower bottle cap (3) have the circular hole (2) of 6-12mm, and what carried on the back dorsad at the back side of upper bottle cover (1), lower bottle cap (3) is bonded as one.
