Abstract

The invention belongs to teaching aid technical field, it is related to a kind of geographical teaching aid, specifically a kind of the torrential currents of the Yellow River enters extra large model, it is made up of small ball and a thermoplastic molding duroplasts film shell two parts, the torrential currents of the Yellow River produced using the technical program enters extra large model, because it is to roll to do dynamic the Yellow River and enter extra large demonstration in the U-lag in the Yellow River mainstream with small ball on the low duroplasts film shells with Huanghe valley landform convex-concave feature of the Xi Gaodong of the colored printing of a pane shape and thermoplastic die forming and tributary, so it can more give expression to the geographical knowledge of the Yellow River than the picture and text on the geography textbook of dimensional printing goods visual pattern, teach through lively activities, classmates can be caused to learn the geographical interest in the Yellow River, it is also easier to understand, it is easy to learn easy to remember；It is not only suitable for being used as geographical teaching instrument, and it is also adaptable as toy and uses, and the souvenir that it is more suitable for going sight-seeing the Yellow River is used.

Description

The torrential currents of the Yellow River enters extra large model

Technical field

The invention belongs to teaching aid technical field, it is related to a kind of geographical teaching aid, specifically a kind of the torrential currents of the Yellow River to enter Extra large model.

Background technology

The Bayan Har arteries and veins of Qinghai-Tibet Platean is risen in the Yellow River, and about 5464 kilometers of total length is Chinese second long river, the world the Six long rivers, flow through Qinghai, Sichuan, Gansu, Ningxia, the Inner Mongol, Shaanxi, Shanxi, Henan, nine, Shandong provinces and regions, most from West to East After flow into the Bohai Sea.The Yellow River is the cradle of the Chinese nation, is the mother river of the Chinese nation, and most people is all from geography textbook The geographical knowledge about the Yellow River is acquired, but geography textbook is the graph-text content of planographic, it is dry as dust, it is not visual in image, It is and the sand table yellow River model of solid is although visual in image but heavy, it is difficult to transport and carries, and high cost, can not be in geography Classroom Shang Zuo the Yellow River enters the demonstration in sea.

The content of the invention

Present invention solves the technical problem that being to provide a kind of geographical teaching instrument the torrential currents of the Yellow River enters extra large model, it can be on ground Reason classroom Shang Zuo the Yellow River enters the dynamic demonstration in sea.

The present invention is adopted the technical scheme that：The torrential currents of the Yellow River enters extra large model, and it is hard by small ball and a thermoplastic molding Plastic sheeting shell two parts are constituted, it is characterized in that：The thermoplastic molding hard plastic shell that the torrential currents of the Yellow River enters extra large model is in duroplasts Film is enameled and is printed with the topographic map of the Huanghe valley, and thermoplastic is molded out corresponding with Huanghe valley topographic map on the topographic map Kame-and-kettle topography model, the Qinghai-Tibet model for having the Huanghe valley on the kame-and-kettle topography model, mountain range model, lake model, loess The bottom of plateau gully model, the Yellow River mainstream and branch flow model, described the Yellow River mainstream and branch flow model is smooth U-lag, China There is folding upwards at Beijing master mould, the deep depression model of aboveground river model and Bohai Sea sea, the edge of the deep depression model in Bohai Sea sea The side risen is sea level, and the upper surface that the torrential currents of the Yellow River enters extra large model is the low rectangle models of Xi Gaodong, the rectangle model Southern side face on be printed on the height above sea level chart of place name along the river from the Sources of the Yellow River to estuary, on the north side face of the rectangle model The place name along the river from the Sources of the Yellow River to estuary is printed on to be printed on from the Yellow River on length chart, the west side face of the rectangle model Source is printed on Bohai Sea to the chart of the length, flow and drainage area in each tributary of estuary on the east side face of the rectangle model Extra large bathygram table, it is a molding that the torrential currents of the Yellow River enters the upper surface of extra large model, southern side face, west side face, north side face and east side face The duroplasts film shell of shaping；The small ball that the torrential currents of the Yellow River enters extra large model is small steel ball, small bead or other heavy materials Small ball；One or more small balls are placed in the U-lag of the Yellow River mainstream or tributary upstream, small ball can be rolled forward It is dynamic, finally roll into the deep depression model in Bohai Sea sea of east.

The torrential currents of the Yellow River produced using above technical scheme enters extra large model, because it is in a pane with small ball On the Xi Gaodong of the shape colored printing and thermoplastic die forming low duroplasts film shell with Huanghe valley landform convex-concave feature The Yellow River mainstream and tributary U-lag in roll and do dynamic the Yellow River and enter extra large demonstration, so its geography religion than dimensional printing goods Picture and text on section's book can more give expression to the geographical knowledge of the Yellow River visual pattern, teach through lively activities, and classmates can be caused to learn the Yellow River Geographical interest, is also easier to understand, easy to learn easy to remember；It is easy to stack transport and carries, system than sand table yellow River model light weight Easy low cost is made, teaching aid popularization is suitable as, it is not only suitable for being used as geographical teaching instrument, and it is also adaptable as toy Use, the souvenir that it is more suitable for going sight-seeing the Yellow River is used.

Specific embodiment

In Fig. 1, the torrential currents of the Yellow River that the present invention is provided enters extra large model, and it is by small ball and a thermoplastic molding duroplasts Film shell two parts are constituted, it is characterized in that：The thermoplastic molding hard plastic shell that the torrential currents of the Yellow River enters extra large model is in duroplasts film Enamel and be printed with the topographic map of the Huanghe valley, thermoplastic is molded out convex-concave corresponding with Huanghe valley topographic map on the topographic map Relief model, the Qinghai-Tibet model for having the Huanghe valley on the kame-and-kettle topography model, mountain range model, lake model, loess plateau The bottom of gully model, the Yellow River mainstream and branch flow model, described the Yellow River mainstream and branch flow model is smooth U-lag, and North China is put down Master mould, the deep depression model of aboveground river model and Bohai Sea sea, the edge of the deep depression model in Bohai Sea sea has what is be folded up While being sea level, the torrential currents of the Yellow River enters the upper surface of extra large model（1.1）It is the low rectangle models of Xi Gaodong, the rectangle model Southern side face（1.2）On be printed on the height above sea level chart of place name along the river from the Sources of the Yellow River to estuary, the north of the rectangle model The place name along the river from the Sources of the Yellow River to estuary is printed on side apart from length chart, the west side face of the rectangle model（1.3） On be printed on each tributary from the Sources of the Yellow River to estuary length, flow and drainage area chart, the east of the rectangle model Side（1.4）On be printed on Bohai Sea bathygram table, the torrential currents of the Yellow River enters the upper surface of extra large model（1.1）, southern side face（1.2）, west side Face（1.3）, north side face and east side face（1.4）It is a duroplasts film shell for die forming；The torrential currents of the Yellow River enters extra large model Small ball（2）It is the small ball of small steel ball, small bead or other heavy materials（2）；One or more small balls（2）It is placed on In the U-lag of the Yellow River mainstream or tributary upstream, small ball can rolls forward, finally roll into the deep depression model in Bohai Sea sea of east It is interior.
