[0037] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0038] Example 1

[0039] To address the issues of poor interactivity, unsatisfactory display effects, and difficulty for residents to view urban renewal project models from multiple perspectives in existing systems, please refer to [the relevant documentation / reference]. Figure 1 This invention provides a visualization model display system for urban renewal projects, including a display platform 1 and a display panel 2 located on top of the platform 1. Multiple height-adjustable and rotatable model components 3 are mounted on the display panel 2. Multiple equally spaced strip grooves 102 are provided on the front inclined plate of the platform 1, with pull rods 103 within each groove for adjusting the state of the model components 3. An interactive screen 101 is located on the front inclined plate below the grooves 102, and speakers 104 are located on the sides of the grooves 102. A movable door 105 is located on the back of the platform 1. This device is installed near the area requiring urban renewal to facilitate the display of information about urban renewal to the surrounding community. It prints out elements such as buildings and roads in the urban renewal project with high precision and displays them in a three-dimensional form, greatly improving intuitiveness. The height and angle of the model components 3 can be adjusted via the pull rods 103 to allow for multi-angle viewing by the surrounding community. The interactive screen 101 enables network interaction, allowing the community to fully understand all aspects of the urban renewal project.

[0040] like Figure 4 As shown, both ends of the display panel 2 are fixed with support rods 201 for supporting the rotation of the spherical transparent cover 4, and the support rods 201 are fixedly attached to the display platform 1; a through hole is formed between the display panel 2 and the display platform 1 for the spherical transparent cover 4 and the 3D printed component 7 to pass through.

[0041] To facilitate viewing of the visualized model from different angles by the surrounding public, improve the display effect, and enhance the interactivity of the device with the human body, such as... Figures 5-6 As shown, model component 3 includes a mounting plate 301 located above display panel 2 and a model body 302 fixedly adhered to the top of mounting plate 301. A ring of evenly distributed LED beads 303 is provided at the top edge of mounting plate 301. The LED beads 303 facilitate nighttime display of model component 3, enhancing the aesthetics of the device. A lifting screw 304 is fixedly provided at the bottom of mounting plate 301, and a screw sleeve 305 is fitted onto the lifting screw 304, which is fixed to the bottom of display panel 2. A rotating rod 307 and a bearing seat 308 are respectively located directly below the lifting screw 304. The rotating rod 307 rotatably resides within the bearing seat 308, which is fixed to display panel 2 by a bracket. A movable insertion point is fixed at the bottom end of the lifting screw 304. The square insert rod 306 inside the rotating rod 307 allows the lifting screw 304 to rise and fall simultaneously while rotating. The model assembly 3 also includes a worm gear 309 fixedly sleeved at the bottom of the rotating rod 307 and a fixed seat 310 located on the side of the worm gear 309. The fixed seat 310 is rotatably provided with a worm gear 311 meshing with the worm gear 309 and a drum 312 fixedly connected to the worm gear 311. A pull rope 313 is wound on the drum 312, and the end of the pull rope 313 is fixedly connected to the pull rod 103. A torsion spring 314 is provided on the rotating shaft of the drum 312 at the end of the fixed seat 310. The support rod 201 is provided with a through hole 202 for the pull rope 313 to pass through, and the bottom of the display plate 2 is provided with a guide groove for limiting the pull rope 313.

[0042] Based on the model component 3 to be viewed, pull down the corresponding lever 103. Lever 103 moves the pull rope 313, which in turn rotates the drum 312. At this time, the torsion spring 314 is compressed or twisted, storing energy. The drum 312 rotates the worm gear 311, which in turn rotates the worm wheel 309. The worm wheel 309 rotates the rotating rod 307, which in turn rotates the lifting screw 304 via the square insert rod 306. The lifting screw 304 rises during rotation, causing the mounting plate 301 and the model body 302 on it to rotate and rise, thus facilitating multi-angle viewing for the surrounding crowd and greatly improving intuitiveness. When the lever 103 is released, the torsion spring 314 releases its stored energy, and the resulting restoring force drives the lifting screw 304 back to its initial position. The lever 103 allows interaction with the model component 3, and the pulling operation of the lever 103 also has a certain game effect, encouraging people with children to stop and watch.

[0043] Example 2

[0044] Based on Embodiment 1, in order to make the device suitable for outdoor use and to prevent the model component 3 from being damaged by human intervention, such as Figures 2-3 As shown, it also includes a spherical transparent cover 4 for covering the display panel 2. The spherical transparent cover 4 can effectively protect the model components 3 from weather or human damage, and the spherical shape also makes it convenient for people to view from all angles.

[0045] like Figures 7-8 As shown, the spherical transparent cover 4 includes a first hemisphere 401 and a second hemisphere 402 that are magnetically attracted to each other. The end face of the first hemisphere 401 has multiple semi-open slots 403 evenly distributed along the circumference. A first magnet 404 is provided on the closed side of each semi-open slot 403. The end face of the second hemisphere 402 has multiple second magnets 405 evenly distributed along the circumference. The second magnets 405 are inserted into the semi-open slots 403 and rotated to engage with the first magnets 404. The first hemisphere 401 and the second hemisphere 402 can be easily opened, facilitating maintenance of the internal model components 3.

[0046] To address the issue that the existing model component 3 lacks real-time update capabilities and thus fails to accurately reflect the progress of urban renewal projects, such as... Figure 7 , Figure 10As shown, the interior of the spherical transparent cover 4 houses a 3D printing component 7 for printing a visual model of the model assembly 3. The 3D printing component 7 includes a hollow frame 701 fixed inside the spherical transparent cover 4. A 3D printing unit 702 and a liquid storage cylinder 703 are respectively located on both sides of the hollow frame 701. Multiple liquid storage cylinders 703 are used to supply liquid to the 3D printing unit 702, and each cylinder has an electrically controlled valve 704 on its feed pipe. Multiple liquid storage cylinders 703 can store liquids of different colors to facilitate the printing of different model bodies 302. The 3D printing unit 702, using existing technology, can move in a plane with an adjustable height to adapt to the printing of different model bodies 302. Based on real-time data from urban renewal projects, the model body 302 is updated using the 3D printing component 7, resulting in good integration with the actual update progress.

[0047] To avoid the 3D printed component 7 affecting the display effect, such as Figure 3 , Figure 9 As shown, the upper back of the display stand 1 is equipped with a drive mechanism 5 for rotating the spherical transparent cover 4. The drive mechanism 5 includes a motor 504 and a second gear 503 fixedly sleeved on the output shaft of the motor 504. Above the second gear 503, there is a gear ring 501 meshing with it and a support frame 502 for supporting the gear ring 501. The gear ring 501 is detachably installed at the end of the spherical transparent cover 4 by fasteners. In use, the motor 504 drives the second gear 503 to rotate, the second gear 503 drives the gear ring 501 to rotate, the gear ring 501 drives the spherical transparent cover 4 to rotate, and the spherical transparent cover 4 drives the 3D printing component 7 inside to rotate. When the 3D printing component 7 is not in use, it can be concealed to avoid affecting the display. During the rotation of the 3D printing component 7, the liquid storage cylinder 703 can also be shaken, making the liquid inside more uniform.

[0048] Example 3

[0049] Based on Embodiments 1 and 2, in order to address the problem that dust easily adheres to the surface of the spherical transparent cover 4 and affects the display effect because the device is built near the renewal area, such as... Figure 7As shown, the internal cavity of the display stand 1 is equipped with a cleaning component 6 for cleaning the surface of the spherical transparent cover 4. The cleaning component 6 includes a mounting base 601 and a horizontal tube 603 located on the side of the mounting base 601. Cleaning brushes 602 that abut against the spherical transparent cover 4 are provided on both sides of the mounting base 601. Multiple nozzles 604, evenly spaced, are provided at the top of the horizontal tube 603 for spraying cleaning fluid onto the surface of the spherical transparent cover 4. A water pump 605 and a cleaning fluid tank 606 are respectively provided at the ends of the horizontal tube 603. The water pump 605 is used to draw cleaning fluid from the cleaning fluid tank 606 into the horizontal tube 603. As the spherical transparent cover 4 rotates, cleaning fluid is sprayed onto its surface through the nozzles 604, and the cleaning brushes 602 remove dust adhering to the surface, allowing onlookers to clearly view the model component 3.

[0050] Example 4

[0051] Based on Embodiments 1, 2, and 3, the present invention provides a method for displaying a visualization model of urban renewal projects, comprising the following steps:

[0052] S1. Pull the lever 103 to adjust the height and angle of model component 3, and display model component 3;

[0053] S2. Based on the urban appearance change data collected by the municipal system (the collected urban appearance images are compared with the urban appearance images collected in the previous period, and the changed locations are integrated into three-dimensional model data using the image recognition module), the 3D printing component 7 receives the data. During idle periods (non-display periods, such as nighttime), the spherical transparent cover 4 is rotated by the drive mechanism 5, and the 3D printing component 7 is rotated above the model component 3. Based on the visualized model of the model component 3, the visualized model is updated by the 3D printing component 7 and the display continues.

[0054] During the rotation of the spherical transparent cover 4, the surface of the spherical transparent cover 4 is cleaned by the cleaning component 6; after the visualization model is updated, the 3D printing component 7 is rotated into the display stand 1 by the drive mechanism 5.

[0055] The above-described embodiments are merely one implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
