Description

A kind of piestic water demonstrating model

Technical field

The utility model relates to the teaching mode field, is specifically related to a kind of piestic water demonstrating model.

Background technology

Piestic water is phreatic a kind of, is formed at up and down in the water-bearing zone between two fluid-tight water-resisting layers.This water-bearing zone is generally the more sandstone of hole or contains the more rocks such as ls in crack.Region of intake, confined area and discharge area can be told in the relevant zone of piestic water distribution.At confined area since on cover aquiclude, the pressure that underground water receiving waters own wt forms becomes piestic water.The zone well-digging that is lower than the piestic water rising water stage on confined area ground can form gravity well, and face of land higher position then shows as common well, and the natural place of exposing of piestic water often forms spring.

Yet in the traditional geographic teaching, the teacher is when introducing the formation reason of piestic water; The student is difficult to understand, because the process of its formation is all carried out underground, the student can't see entirely with the imagination at ordinary times; Generally all be that the teacher is student explain in the prior art on plane map, because its each ingredient is all directly perceived inadequately, so; The student can't see annexation and the water-head between it, thus be unfavorable for understanding, the teacher explain also require great effort time-consuming.

The utility model content

For addressing the above problem, it is a kind of reasonable in design, directly perceived and be convenient to a kind of piestic water demonstrating model of students understand that the purpose of the utility model is to provide.

For achieving the above object, the technical scheme of the utility model is: a kind of piestic water demonstrating model, to form by base, miniature water circulating pump and ore deposit, ground model, and ore deposit, said ground model comprises concave and convex ground top layer, sand layers and transparent water pipe; Said transparent water pipe comprises horizontal water pipe, well casing, gravity flow well casing, spring pipe and the recirculatory pipe of mutual perforation; Said miniature water circulating pump is located in the said base, and ore deposit, said ground model is located on the said base; Said sand layers is located in the said horizontal water pipe;

Said horizontal water pipe level is located at the side edge between base and ore deposit, the ground model; Said well casing is vertical at the protruding place of side on said concave and convex ground top layer; Said gravity well is located at the side recess on said concave and convex ground top layer, and said spring pipe is located at the protruding place of side and the place, the slope between the recess on said concave and convex ground top layer; Said water circulating pump is located between said horizontal water pipe and the said recirculatory pipe.

Preferably, protrusion place, surface, said concave and convex ground top layer is made as brown representative massif, and said concave and convex ground top layer surface concave is made as the green mountain valley of representing.

Preferably, said base side is printed on the brief introduction board that literal is used to introduce the piestic water origin cause of formation above also being provided with.

Adopt the beneficial effect of present technique scheme to be: through piestic water being formed reason through the stereoscopic model simulation; Water circulating pump is fetched water in horizontal water pipe, well casing, gravity flow well casing and spring pipe; Flow back to from recirculatory pipe again; How simulation gravity well, spring form through underground piestic water, thereby have arrived reasonable in designly, intuitive and reliable, and are convenient to the purpose of students understand.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.

Embodiment.

As shown in Figure 1, a kind of piestic water demonstrating model is made up of base 1, miniature water circulating pump 2 and ore deposit, ground model 3, and ore deposit, said ground model 3 comprises concave and convex ground top layer 4, sand layers 5 and transparent water pipe; Said transparent water pipe comprises horizontal water pipe 61, well casing 62, gravity flow well casing 63, spring pipe 64 and the recirculatory pipe 65 of mutual perforation; Said miniature water circulating pump 2 is located in the said base 1, and ore deposit, said ground model 3 is located on the said base 1; Said sand layers 5 is located in the said horizontal water pipe 61;

Said horizontal water pipe 61 levels are located at the side edge between base 1 and ore deposit, the ground model 3; Said well casing 62 is vertical at the protruding place 41 of side on said concave and convex ground top layer; Said gravity flow well casing 63 is located at the side recess 42 on said concave and convex ground top layer 4, and said spring pipe 64 is located at the protruding place 41 of side and the place, the slope between the recess 42 on said concave and convex ground top layer 4; Said water circulating pump 2 is located between said horizontal water pipe 61 and the said recirculatory pipe 65.

Wherein, in order to make 4 surfaces, said concave and convex ground top layer image more, the protruding place 41 on said concave and convex ground top layer 4 is made as brown representative massif, said concave and convex ground top layer 4 surface concave 42 are made as the green mountain valley of representing; In order to make the student can combine character introduction,, above also being provided with, said base 1 side is printed on the brief introduction board 7 that literal is used to introduce the piestic water origin cause of formation so that understand.

Principle of work is; As depicted in figs. 1 and 2, at first start water circulating pump 2 and fetch water and simulate artesian pressure, water flows to horizontal water pipe 61 earlier; Because laterally water pipe 61 is to connect each other with well casing 62, gravity flow well casing 63, spring pipe 64 and recirculatory pipe 65; So when water flows to the gravity flow well casing 63 of recess 42 on the low concave and convex ground top layer 4 of water level, will upwards spray, simulation is lower than the gravity well that the zone well-digging of piestic water rising water stage forms on confined area ground.When water flows to the well casing 62 at protruding place 41 on the higher concave and convex ground top layer 4 of water level, will certain distance be arranged from the protruding place 41 on concave and convex ground top layer 4, simulation flows to the common well of face of land higher position performance when water.When water flows between the protruding place 41 on concave and convex ground top layer 4 and recess 42 spring pipe 64 places on the slope, will upwards overflow, the natural place of exposing of simulation piestic water often forms spring.

Adopt the beneficial effect of present technique scheme to be: through piestic water being formed reason through the stereoscopic model simulation; Water circulating pump 2 is fetched water in horizontal water pipe 61, well casing 62, gravity flow well casing 63 and spring pipe 64; Flow back to from recirculatory pipe 65 again; How simulation gravity well, spring form through underground piestic water, thereby have arrived reasonable in designly, intuitive and reliable, and are convenient to the purpose of students understand.

Above-described only is a kind of piestic water demonstrating model preferred implementation of the utility model; Should be understood that; For the person of ordinary skill of the art; Under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
