Description

Pearl River water circulation model

Technical field

The invention belongs to teaching aid technical field, it is related to a kind of geographical or natural teaching aid, specifically a kind of Zhujiang River Water circulation model.

Background technology

The Zhujiang River is Chinese second great river, and the 3rd long river, Zhujiang River original refers to Guangzhou to 96 kilometers of long one section water channels of estuary, after To be increasingly becoming the general name in each bar river on the Xijiang River, Dong Jiang, Bei Jiang and the Delta of the Pearl River.The Zhujiang River rises in Yunnan-Guizhou Plateau crow illiteracy Mountain system Ma Xiongshan, 2320 kilometers of total length, flows through the provinces and regions of Central and Western China six and North Vietnam, is injected in downstream from eight estuarys The South Sea.Most people is all that the geographical knowledge about the Zhujiang River is acquired from geography textbook, but geography textbook is planographic Graph-text content, it is dry as dust, not visual in image, and three-dimensional sand table Zhujiang River model is although visual in image but heavy, be difficult fortune Defeated and carrying, and cost is high, and the demonstration of Zhujiang River water circulation can not be done in geography class one's parents.

The content of the invention

Present invention solves the technical problem that being：A kind of educational aid Pearl River water circulation model of geographical or natural science is provided, It can do the dynamic demonstration of Zhujiang River water circulation on geographical or natural classroom.

The present invention is adopted the technical scheme that：Pearl River water circulation model, it is by electric micro-sprayer and a thermoplastic Duroplasts film shell two parts are molded to constitute, it is characterized in that：Pearl River water circulation model thermoplastic molding duroplasts film shell be Duroplasts film, which is enameled, is printed with the topographic map of Pearl River Delta, and thermoplastic is molded out and Pearl River Delta topographic map on the topographic map There are the Yunnan-Guizhou Plateau model of Pearl River Delta, mountain range model, mountain and hill on corresponding kame-and-kettle topography model, the kame-and-kettle topography model Model, lake model, Huangguoshu Waterfall model, Zhujiang River mainstream and branch flow model, Plain model, eight estuary models and the South Sea Extra large deep depression model, the edge of the deep depression model in South Sea sea has the side being folded up to be pond, the Pearl River water circulation model Upper surface be the low rectangle model in the high southeast in northwest, the southern side face of the rectangle model is the section mould on the basis of seabed Type, is printed on riverine place name height above sea level chart and bathygram table from the Xijiang River source to estuary, the rectangle on the face of southern side The north side face of model is the section model on the basis of seabed, be printed on the face of north side from northern Jiang Yuantou to estuary riverinely Name apart from length chart, the west side face of the rectangle model is the section model on the basis of seabed, be printed on the face of west side from Xijiang River source to the length in each tributary of estuary, flow and drainage area chart, the east side face of the rectangle model be with Section model on the basis of seabed, is printed on from Dong Jiang source to estuary each height above sea level chart riverinely on the face of east side, should Upper surface, southern side face, west side face, north side face and the east side face of Pearl River water circulation model are the duroplasts films of a die forming Shell；The electric micro-sprayer of the Pearl River water circulation model is arranged on the pond inner surface of rectangle hard plastic shell, miniature electric The water inlet pipe of sprayer is connected with the water of the model, the outer surface of electric micro-sprayer with " evaporation " word, it is miniature With the word of " wind " on four outlet pipes of power spraye, reach at the Zhujiang River mainstream and tributary source of the model and connect dress The shower nozzle of cloud shape is adornd into, electric micro-sprayer is started, water smoke is with regard to that can fall on the mold, mainstream and tributary through the Zhujiang River Flow forward, is finally flowed into the pond in the deep depression model in South Sea sea.

The Pearl River water circulation model produced using above technical scheme, because it is to be sprayed on one with electric micro-sprayer Low hard with Pearl River Delta landform convex-concave feature in the high southeast in northwest of individual pane shape colored printing and thermoplastic die forming Flowing and " sea evaporation ", " wind model " do the dynamic Zhujiang River to " rainy " in Zhujiang River mainstream and tributary on plastic sheeting shell Water circulation is demonstrated, so it can more give expression to the ground of the Zhujiang River visual pattern than the picture and text on the geography textbook of dimensional printing goods Knowledge is managed, is taught through lively activities, classmates can be caused to learn the geographical interest of the Zhujiang River, is also easier to understand, it is easy to learn easy to remember；It compares sand table Zhujiang River model quality is light, is easy to stack transport and carries, cost easy to manufacture is low, is suitable as teaching aid popularization, it is not only suitable for Used as geographical teaching instrument, it is also adaptable as toy and used, the souvenir that it is more suitable for going sight-seeing the Zhujiang River is used.
