Abstract
The invention relates to a device for demonstrating an eddy phenomenon, which comprises a transparent cylindrical bucket, a water supply pipe, a demonstrating rack and a water pump, wherein the transparent cylindrical bucket is arranged on the demonstrating rack; the water pump is positioned in the demonstrating rack; the water supply pipe is positioned on the outside of the transparent cylindrical bucket, and the upper end of the water supply pipe is communicated with an outlet elbow; the other end of the outlet elbow is provided with a water outlet extending into the upper part of the transparent cylindrical bucket; the lower end of the water supply pipe is connected with the water outlet of the water pump; the center of the bottom of the transparent cylindrical bucket is provided with a backwater hole; and the water inlet of the water pump is communicated with the backwater hole of the bucket so as to form an enclosed circulating system. The device is the enclosed circulating system; the eddy phenomenon is generated in the transparent cylindrical bucket in the enclosed circulating system by sucking and pumping water through the water pump; and the eddy phenomenon can be demonstrated visually, vividly and correctly. The device has a reasonable design and a simple structure, and can be widely applied to popular science education or teaching.
Description
Technical field
The invention belongs to the teaching aid field that is used for Popular Science Education, be specifically related to a kind of exhibiting device of demonstrating the whirlpool phenomenon.
Background technology
This whirlpool phenomenon shows that equipment is at liquid, such as water, wet goods.Do not comprise gas.The key property of whirlpool is: the flow velocity of certain point and this product of putting radius of living in remain unchanged on same surface level.Just speed is fast more more inward for whirlpool, and pressure is more little, so whirlpool has the entad strength of suction.In daily life, we can see that the phenomenon of whirlpool can take place when having a large amount of water to sweep away for bathtub, health platform basin, toilet seat toilet etc.Usually have the showpiece of showing whirlpool generation phenomenon at science popularization venue (comprising external venue), it be with pump from the bottom margin opening part of transparent bucket along bucket wall pumps water, allow current slowly rise, and formed the whirlpool phenomenon along the rotation slowly of bucket wall.But the phenomenon of demonstration is opposite therewith just for the principle of the formation of whirlpool, and it begins to form from the water surface.
Summary of the invention
In order correctly to demonstrate the phenomenon that whirlpool takes place, the object of the present invention is to provide the apparatus for demonstrating of a kind of whirlpool phenomenon of correct displaying whirlpool generation.
Concrete structural design scheme is as follows:
A kind of apparatus for demonstrating of whirlpool phenomenon comprises transparent cylinder staving 3, flow pipe 5, demonstration stand 1 and water pump 2; Transparent cylinder staving 3 is positioned on the demonstration stand 1, and water pump 2 is positioned at demonstration stand 1; Flow pipe 5 is positioned at transparent cylinder staving 3 outsides, and its upper end is being communicated with Discharging bent-tube 6, and the other end of Discharging bent-tube 6 is the water delivering orifice 7 that stretches in transparent cylinder staving 3 tops; The lower end of flow pipe 5 links to each other with the water delivering orifice of water pump 2; Transparent cylinder staving 3 bottom centre are provided with backwater hole 4; The water inlet of water pump 2 is connected with the backwater hole of staving 4, forms the circulation system of a sealing.
The water delivering orifice 7 of described Discharging bent-tube 6 is positioned at the tangential direction of transparent cylinder staving 3 inwalls.
The diameter of described transparent cylinder staving is 300～400mm, highly is 1800～2500mm that the diameter of Discharging bent-tube is 32mm.
The apparatus for demonstrating of whirlpool phenomenon of the present invention is a closed circulation system, by the suction and the pumps water of water pump, produces the whirlpool phenomenon in the transparent drum in the circulation system of a sealing.Can be intuitively, image, correctly show the phenomenon that whirlpool takes place.The present invention is reasonable in design, and is simple in structure, can be widely used in Popular Science Education or teaching.

Fig. 2 is a structure side view of the present invention.
Fig. 3 is a structure vertical view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described by embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of apparatus for demonstrating of whirlpool phenomenon comprises transparent cylinder staving 3, flow pipe 5, demonstration stand 1 and water pump 2; Transparent cylinder staving 3 is positioned on the demonstration stand 1, and water pump 2 is positioned at demonstration stand 1.Flow pipe 5 is positioned at transparent cylinder staving 3 outsides, and its upper end is being communicated with Discharging bent-tube 6, and the other end of Discharging bent-tube 6 is the water delivering orifice 7 that stretches in transparent cylinder staving 3 tops, and water delivering orifice 7 is positioned at the tangential direction of transparent cylinder staving 3 inwalls; The lower end of flow pipe 5 links to each other with the water delivering orifice of water pump 2; Transparent cylinder staving 3 bottom centre are provided with backwater hole 4; The water inlet of water pump 2 is connected with staving backwater hole 4, forms the circulation system of a sealing.
Whirlpool is that the centrifugal force of the water that tangentially injects owing to Discharging bent-tube 6 and the gravity acting in conjunction of self produce in this device.Through test, the formation of whirlpool and relating to parameters such as water inlet flow velocity, water inlet diameter, flow of inlet water.The diameter of the transparent cylinder staving 3 of this device is 360mm, highly for 2000mm, the diameter of Discharging bent-tube 6 is 30mm, the flow of water pump 2 is 80-160l/min.
During demonstration, earlier with fills with water in the transparent cylinder staving 3 (to the position at flow pipe 5 tops), press power switch then and start water pump, send water for flow pipe 5, in the circulation system of this sealing, just can see the whirlpool phenomenon by transparent drum by the suction of water pump 2.
