Abstract
The utility model discloses a device for demonstrating a vortex phenomenon, which is composed of a transparent barrel body, a water pump and a water supply pipe, wherein the top center of the barrel body is provided with a water inlet hole, the bottom center of the barrel body is provided with a water outlet hole and a blank pipe of an inverted blank pipe funnel corresponds to the water inlet hole at the lower part of the water inlet hole. The water pump is arranged at the lower part of the barrel body, a water inlet mouth of the water pump is connected with the water outlet hole of the bottom of the barrel body, a water outlet mouth of the water pump is connected with the water inlet hole of the barrel body through the water supply pipe, thereby, a close circulating system is formed. Through the suction of the water pump and the water supplied for the blank pipe funnel, the device can be used for intuitively and visually showing a vortex occurring phenomenon generating in the close circulating system, a vortex forming principle is also incarnated fully and the utility model is really a popular science show product which follows science.
Description
One, technical field
The utility model relates to a kind of vortex phenomenon apparatus for demonstrating.
Two, background technology
The vortex that we mentioned is generally at liquid, such as water.Typhoon is another kind of vortex, is cyclone again.Vortex has a key property: the flow velocity of certain point and this product of putting radius of living in remain unchanged on same surface level.Be vortex speed is fast more more inward, pressure is more little, so vortex entad has the effect of suction.So we often can see that the reason of vortex can take place when having a large amount of water to sweep away for bathtub, health platform basin, toilet seat toilet etc.
Science popularization venue in the past (comprising external venue) also once had the showpiece of showing vortex generation phenomenon, but its principle just with really be opposite, it be with pump from the bottom margin opening part of bucket along bucket wall pumps water, allow current slowly rotate rising, thereby form so-called vortex phenomenon.This is very unscientific attitude, spectators is had very serious misleading.
Three, utility model content
Goal of the invention of the present utility model is to remedy the blank that prior art exists, and a kind of apparatus for demonstrating that can effectively demonstrate vortex generation phenomenon is provided.
The utility model vortex phenomenon apparatus for demonstrating, constitute by transparent staving, water pump, flow pipe, the top center of staving is provided with the inlet opening, staving bottom centre sets out the water hole, the blind pipe of inverted blind pipe funnel is relative with the inlet opening in the bottom of inlet opening, and water pump is arranged at the bottom of staving, and the water inlet of water pump links to each other with staving bottom apopore, the water delivering orifice of water pump links to each other with the staving inlet opening by flow pipe, thereby forms the circulation system of a sealing.
This device by the suction of water pump and the water that send of giving the blind pipe funnel, produces vortex phenomenon in the circulation system of this sealing.
The utility model vortex phenomenon apparatus for demonstrating can be showed the phenomenon that vortex takes place intuitively, visually, embodies the principle that vortex forms again fully, a kind of science popularization exhibit of following science of can yet be regarded as.
Four, description of drawings
Fig. 1 is the utility model vortex phenomenon apparatus for demonstrating structural representation.
Five, embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1, the utility model vortex phenomenon apparatus for demonstrating, constitute by transparent organic glass staving 1, water pump 2, flow pipe 3, the top center of staving is provided with inlet opening 6, staving bottom centre sets out water hole 5, the blind pipe 7 of inverted blind pipe funnel 4 in the inlet opening 6 bottom relative with inlet opening 6, water pump 2 is arranged at the bottom of organic glass staving 1, the water inlet of water pump 2 links to each other with staving apopore 5, the water delivering orifice of water pump 2 links to each other with staving inlet opening 6 by flow pipe 3, thereby forms the circulation system of a sealing.
During use, open water pump,, in the circulation system of this sealing, produce vortex phenomenon by the suction of water pump and the water that send of giving the blind pipe funnel.
