Energy-saving and environment-friendly sand table based on urban planning three-dimensional display

Abstract

The invention provides an energy-saving and environment-friendly sand table based on urban planning three-dimensional display, and relates to the technical field of urban planning sand tables. The sand table comprises a table body, a display board, a seat frame, a transmission structure and shielding boards; a display cavity and an annular cavity are further formed in the inner side of the table body, threaded rods are rotationally installed in the middles of the two ends of the annular cavity respectively, the two ends of each threaded rod are of an optical axis structure respectively, the bottom ends of the threaded rods are in transmission connection with the transmission structure, the display board is installed in the display cavity and installed on the two threaded rods, the two shielding boards are inserted into penetrating holes of the table body respectively, racks are further arranged at the two ends of the shielding boards respectively, a model is clamped by sliding clamping pieces so that replacement can be facilitated, the display board is driven to ascend through the threaded rods, the two shielding boards are driven to be opened, and when the display board descends, the two shielding boards can be driven to be closed. The problems that most models adhere to a display stand, replacement is troublesome, and a structure for protecting and covering the models is lacked are solved.

Description

technical field [0001] The invention relates to the technical field of urban planning sand table, in particular to an energy-saving and environment-friendly sand table based on the three-dimensional display of urban planning. Background technique [0002] At present, in order to develop new energy, the country has made great efforts for environmental protection, carbon peaking, and carbon neutrality. It is not a new word. Most provinces and cities in China are hit by power shortages. In some places, power plants are short of coal storage. As a last resort, they even cut off power. Looking back, at present, in land planning and urban local layout design, it is often used The sand table is displayed. Through the design and layout of the model, the overall appearance of the design can be reflected in the sand table. At present, the traditional sand table, whether it is the land planning or the local layout of the urban planning, has a relatively simple structure and is mostly g...

[0002] At present, in order to develop new energy, the country has made great efforts for environmental protection, carbon peaking, and carbon neutrality. It is not a new word. Most provinces and cities in China are hit by power shortages. In some places, power plants are short of coal storage. As a last resort, they even cut off power. Looking back, at present, in land planning and urban local layout design, it is often used The sand table is displayed. Through the design and layout of the model, the overall appearance of the design can be reflected in the sand table. At present, the traditional sand table, whether it is the land planning or the local layout of the urban planning, has a relatively simple structure and is mostly glued to the display. On the stand, its environmental protection is poor, and it is troublesome to replace the model. When the model is replaced, the glue is easy to remain on the display table, which needs to be disposed of, which is not conducive to environmental protection. Secondly, the model on the sand table also lacks protection and cover. The structure of the sand table is easy to cause damage to the model, and the lighting system of the sand table is in the lighting state for a long time. It can be said that the layout plan of the sand table is rendered through a large number of lights, which is obviously not conducive to energy saving.
