Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1, the embodiment of the utility model provides a river forms demonstrator, be in including mountain region model frame, cover mountain region model frame upper strata mountain region model profile, apply paint with a brush the make scene mud on mountain region model profile upper strata, apply paint with a brush make the mud go up the vegetation powder of mountain body region, set up and be in make the mud go up the regional multiunit lamp area of river course and apply paint with a brush make the mud go up the regional waterscape special effect cream of river course.

The mountain land model frame adopts the high-density polystyrene foam board (EPS) with the length of 60 cm, the width of 40 cm and the thickness of 2 cm as the platform, and then the waste newspaper and the white latex are processed, stacked, molded and fixed to form two miniature mountain land models.

The mountain land model comprises a large mountain land, a small mountain land and a lake center island, the size of the large mountain land is set to be 45 cm, 15 cm and 20 cm, the size of the small mountain land is set to be 40 cm, 12 cm and 15 cm, the size of the lake center island is set to be 5 cm and 2 cm, and the mountain land, the small mountain land and the lake center island are all firmly fixed with the ground land through white latex; the mountain land is provided with a valley, a ridge, a saddle, a cliff and other terrain parts.

The mountain land model profile is covered and attached to the mountain land model after being soaked by the plastic cloth with the length of 10-20 cm and the width of 15 cm, and the plastic cloth is tightly attached to the mountain land model by hand, so that the mountain land has concave-convex feeling. After the gypsum powder on the wetted plastic cloth is dissolved, the plastic cloth is rubbed back and forth by hands, and the gypsum powder is used for completely filling the holes on the plastic cloth, so that the appearance of the mountain model is vivid.

The landscaping mud is used for moulding and coloring simulation of a mountain model, the landscaping mud with the color of the mountain model is diluted by adding water, the landscaping mud is uniformly coated on the plastic cloth by a brush, and the plastic cloth is completely covered. Under the normal temperature, the landscaping mud can be hardened in about 40 minutes generally. The air drying can also be assisted by a blower, and the product is firm and does not crack.

The vegetation powder is used for plant decoration on a mountain land model, white latex is uniformly coated on the dried and solidified mountain land model, and then the vegetation powder mixed with dark green and medium green is timely scattered.

The lamp strip is used for simulating a river on a mountain land model, and 6 small holes penetrating through the foam board are arranged above a valley and a cliff of the mountain land model, and the diameter of each small hole is 4 mm; the lamp area sets up to 6 groups, passes the aperture respectively with the lamp area and is connected with outside power supply system.

The external power supply system can adopt a conventional power supply mode, for example, a lamp strip connection controller and a mobile power supply/charger are adopted, different lines of 6 groups of lamp strips are connected to different interfaces on one LED controller, and then a USB interface is used for connecting positive and negative poles on the LED controller. The small-sized charger baby with the input and output of 5V-1A is used as a power supply and connected with a USB.

The LED superfine flowing water lamp strip is characterized in that the lamp strip is an LED superfine flowing water lamp strip with a waterproof heat-shrinkable sleeve, the diameter of each lamp strip is 3.7 mm, the voltage is 5V, the rated power is 5W/m, the lamp strip is 78 lamps/m, and the light-emitting color is white. The lamp strip exposed out of the valley end is placed and adhered firmly by glue along the flow direction of the river to simulate the flow direction of the river.

The waterscape special effect paste is used for presenting a simulated waterscape on a mountain land model, and is coated on a wood board by using a molding knife, wherein the height of the waterscape special effect paste is 10 cm, 4 cm and about 4 mm in thickness, and the longitudinal grain is provided. After waiting for 1 hour, the strip is taken off from the edge, namely waterfall water flow. Before the waterfall is adhered, a certain amount of waterscape paste is coated on the scarp. And (3) bonding the waterfall to the cliff, coating a certain amount of waterscape paste on the bonding position, and finishing the waterfall after the waterfall is completely dried. The waterscape paste is coated on the whole river channel (on the LED lamp strip) by using a row brush, and the thickness is about 5 mm according to the requirement, so that the waterscape paste can brush the whole river flow direction. And then the shape of the water flow is adjusted by the molding knife. After waiting for 24 hours, the water is completely dried out, and the river waterscape effect is presented.

The following explains the working principle of the river formation demonstrator of the utility model:

the charger connects the USB interface, and the LED superfine flowing water lamp strip is lighted by opening the remote controller switch of the LED controller. The program selects a running water mode, the 6 groups of LED lamp strips flicker from the beginning in sequence, and the process that water flows are converged from a valley zone to form a river is simulated. The trend of the sequential flashing of the LED lamps represents the flowing direction of the river. The speed up/down can be selected, the frequency of lamp flashing is adjusted, and the flow rate of the river is different. The program selects a normally bright mode, and the student can observe the river channel. In a word, the river formation demonstrator can enable students to directly and visually observe the basic situation of river formation in the microscopic mountain land model, assist teaching and easily overcome the serious and difficult point of river knowledge. Meanwhile, the mountainous region model can be used for teaching terrain parts and knowing the terrain parts such as valleys, ridges, saddles, cliffs, mountains and the like. The river formation demonstrator is simple to operate, and even if the river formation demonstrator is separated by tens of meters, the river formation demonstrator can be used for teaching demonstration only by pressing a plurality of keys on the remote controller. Economic environmental protection, it is convenient to remove, does not receive the restriction in place, and application range is wide, has very strong practicality and novelty.
