Description

TECHNICAL FIELD

[0001] The utility model relates to the field of display tools, especially to a three-dimensional sand table for dynamically displaying linear engineering progress. BACKGROUND

[0002] In the field of engineering construction, the sand table as an intuitive and vivid display tool has long played an indispensable role. It not only presents the complex engineering project in the form of a three-dimensional model to help decision-makers, designers and the public quickly understand the project layout, spatial relationship and future appearance, but also promotes the smooth progress of project communication, planning approval and market promotion and other aspects. With the progress of science and technology, especially the development of digital and intelligent technology, engineering construction sand tables are undergoing a profound transformation from traditional hand-made to digital, interactive and intelligent.

[0003] Currently, there are mainly two kinds of sand tables commonly used in the field of engineering construction, namely, physical model three-dimensional sand table and electronic sand table. The physical model three-dimensional sand table usually represents the topographic features in the form of a miniature entity and embodies mountains, water bodies, villages, roads, bridges and other structures in the model, mainly showing the location information and spatial relative relationship of the new project, so that people can understand the macro things from a micro perspective. Its disadvantage is that the visual effect is limited, the construction project may be blocked by the mountains in the model, the construction site cannot be displayed in three dimensions, the information expression is single, and the content presented by the sand table model after completion is basically fixed. The electronic sand table is a system that simulates the topography, urban layout, building community or other specific areas of the real world by using computer technology, three-dimensional modeling technology and multimedia display technology and other modern scientific and technological means. Its disadvantage is that the technical threshold is high, and it requires strong technical background to build a high-quality electronic sand table, including knowledge of three-dimensional modeling, programming and other aspects, with huge cost investment. SUMMARY

[0007] Further, the fixed area is fixed in the base through the fixed leg, and the lifting device is a hydraulic lifting rod or an electric lifting rod.

[0008] Further, the lamp strip comprises at least two lamp strips and is parallelly arranged, and the plurality of lamp strips are different in color.

[0009] Further, the sand table is further provided with a spotlight capable of projecting on the sand table.

[0015] The utility model is further described below in combination with the drawings.

[0016] It should be noted that if the utility model has involved directional indication language, such as up, down, left, right, front, rear, direction language, it is for the convenience of the description of the relative position between components, not for the absolute position of the relative components, the relative position between components, the movement condition and the like in a certain specific posture, if the specific posture changes, the directional indication also changes accordingly. If the utility model has involved the quantity language, such as "many", "multiple", "several" and the like, it specifically refers to two and more than two.

[0017] As shown in Figures 1-3 The utility model provides a three -dimensional sand table for linear engineering progress of dynamic display, including base 1 and sand table 2 in base 1, the projection line on base 1 is divided into fixed area 21 and lifting area 22 along the engineering line trend, and lifting device 3 is arranged between the bottom of lifting area 22 and base 1, the side of lifting area 22 along the engineering line trend is equipped with lamp strip 4, and the trend of lamp strip 4 is consistent with the engineering line trend, a plurality of lamp beads 41 that can be independently controlled bright and dark are evenly arranged in lamp strip 4 along the length direction.

[0018] The sand table 2 mainly includes two functions of engineering information display and engineering progress data display. The engineering information display mainly displays the topography, road traffic, administrative division, engineering buildings and related contents in the construction range involved by the engineering, different types of buildings are identified by different color signs, and county boundaries, city boundaries and the like are identified by electronic lamp strips. The engineering progress data display is mainly for the construction of tunnel engineering, mainly including the construction progress of tunnel excavation and tunnel lining. When the lifting area 22 is not lifted and is flush with the fixed area 21, the overall topography and engineering information of the project site can be directly understood through the sand table 2, and when the engineering progress needs to be understood, the lifting area 22 can be lifted to be higher than the side of the fixed area 21, each lamp bead 41 in the lamp strip 4 is independently controlled by the system, the actual engineering construction progress data is filled into the background program, and the corresponding number of lamp beads 41 is lighted, so that the display of the tunnel engineering progress is realized.

[0019] In the specific production of the sand table 2, the fixed area 21 can be fixed in the base 1 through the fixed leg 5, the lifting device 3 can adopt conventional lifting equipment such as hydraulic lifting rod or electric lifting rod, and remote control is preferably used for control, so as to lift and display at any time.

[0020] Since the current tunnel construction mainly involves two construction processes of tunnel excavation and tunnel lining, the lamp strip 4 preferably includes at least two parallel lamp strips, and each lamp strip 4 displays a process, and the colors of the multiple lamp strips 4 are different, so as to intuitively distinguish the progress of different construction processes.

[0021] In addition, the safety risk point prompt is also an important information in the construction process, and the display method adopted by the utility model is spotlight projection. As shown in the figure, Figure 3 The spotlight 6 is arranged above or obliquely above the sand table 2, so as to facilitate the projection of the text in the spotlight 6 on the corresponding safety risk point in the sand table 2. The spotlight 6 can adopt an intelligent spotlight, which can change the text information projected by the spotlight through the background, so as to realize the dynamic update of the safety risk point.

[0022] The utility model adopts the lifting structure, can directly show the information such as the route direction and position relation of engineering project, the lamp pearl 41 is arranged along the route direction in the lower part of the lifting area, the construction progress information is dynamically displayed through the lighting of the lamp pearl 41, and the safety risk point information in the engineering construction process is dynamically displayed by using the spotlight 6, which can help the project manager to better understand the construction progress and other conditions of each working face. The whole device has relatively low investment cost, good practicability and application value.
