Description

An urban planning booth that simulates light and shadow

technical field

The utility model relates to an urban planning exhibition stand, in particular to an urban planning exhibition stand for simulating light and shadow.

Background technique

The urban planning sand table is the urban topography model, which represents the topographic features of urban planning in the form of miniature entities, and reflects the mountains, water bodies, roads and other objects in the model, so that people can see the big from the small and understand the future urban planning.

Although the urban planning sand table is becoming more and more refined and beautiful, the problem of light and shadow simulation of the sand table has not been solved. The main problem is that it is difficult to simulate the parallel light of the sun. If you make a parallel light source yourself, you need to make a parallel light according to the size of the sand table. , When the sand table is large, it is time-consuming and laborious. If the sun is used as a parallel light source, the sun moves slowly and the direct angle of the sun is fixed within one day, so it is impossible to quickly obtain the light and shadow conditions of different latitudes throughout the year.

Utility model content

The utility model provides an urban planning booth for simulating light and shadow, which solves the problem of light and shadow simulation of the existing sand table.

The technical scheme of the present utility model is realized as follows: an urban planning exhibition stand for simulating light and shadow, including a sand table board, the sand table board is fixed on the turning table, the middle part of the turning table is hinged with the support column, and one side of the turning table is connected with the supporting column. The cylinder is hinged, the support column is fixed on the rotary table, the cylinder is hinged with the rotary table, the rotary table is movable in the base, the rotary table is fixed with a gear ring, the base is provided with a gear set, the base is fixed with a motor, and the motor passes through the gear set drive ring gear.

The sand table board is fixed on the turning table by screws.

The rotary table and the gear set are movably arranged in the base through bearings.

The advantages of the utility model: the use of sunlight as the parallel light source saves the cost of manufacturing the light source, in a relatively short period of time, the sunlight is fixed differently, and the sand table itself rotates and tilts. As a reference object, the sun is a moving object, thus simulating the light and shadow effect on the sand board.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in Figures 1 and 2, an urban planning booth for simulating light and shadow includes a sand table board 1, which is a rigid plastic board for setting buildings and laying roads, and the sand table board 1 is fixed on a turning table 3 by screws 2. On the top, the middle of the turning table 3 is hinged with the support column 4, one side of the turning table 3 is hinged with the cylinder 5, the support column 4 is fixed on the rotary table 6, the cylinder 5 is hinged with the rotary table 6, and the support column 4 is provided with two left and right , to realize the support of the turning table 3, the rotary table 6 is movably arranged in the base 7, the rotary table 6 is fixed with a ring gear 8, the base 7 is provided with a gear set 9, the base 7 is fixed with a motor 10, and the motor 10 passes through the gears. The group 9 drives the ring gear 8, and the rotary table 6 and the gear group 9 are movably arranged in the base 7 through bearings.

When simulating light and shadow, it can be observed with the human eye, but because the sand table rotates, it is difficult to observe, so most of the cameras are fixed on the sand table, and the cameras rotate synchronously with the sand table to record the light and shadow conditions on the sand table. First of all, the entire booth needs to be placed under the sunlight, the motor drives the rotary table to rotate, the cylinder drives the sand table to tilt, and the sand table is used as a reference. It can be used as a video display or as a reference for planning and renovation. According to the direct sunlight angle in different seasons, the angle of the sand table board can be adjusted through the cylinder to quickly obtain the light and shadow conditions within a year.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the within the scope of protection of the present invention.
