Description

Technical Field

[0001] This utility model relates to the field of urban planning display technology, specifically a device for three-dimensional spatial analysis of urban planning. Background Technology

[0002] With the acceleration of urbanization, the scale of cities continues to expand, and their functions become increasingly complex, placing higher demands on the scientific and precise nature of urban planning. Traditional urban planning relies heavily on two-dimensional drawings and simple text descriptions, making it difficult to intuitively display the three-dimensional structure and complex relationships of urban space. It also has obvious limitations in analyzing urban spatial layout, traffic flow, building forms, and the interaction between different functional areas. The emergence of 3D model projectors has brought new technical support to urban planning work. Existing 3D spatial analysis devices used for urban planning are large and mostly fixed, making them inconvenient to carry, and the height of the 3D projection display cannot be adjusted.

[0003] According to the patent application published on the Internet, a device for three-dimensional spatial analysis of urban planning (authorization announcement number: CN220102628U) is described as including "base, top seat, adjustment structure" etc., to realize projection work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This device for three-dimensional spatial analysis in urban planning utilizes a base, a top mount, and an adjustment structure to perform projection. During use, the device is raised and lowered via lifting shafts one and two. However, the lifting height is limited, and the three-dimensional model projection mechanism is fixed to the top mount and cannot be disassembled. This makes it difficult to conveniently move the three-dimensional model projection mechanism to other locations, affecting its versatility and ease of use. Therefore, improvements to this device are needed. Utility Model Content

The limit frame is located to the right of the three-dimensional model projector.

[0009] Preferably, the top of the one-way threaded rod is rotatably connected to the top of the load-bearing frame, and the movable frame is slidably connected to the inside of the load-bearing frame, so that the movable frame can be moved under the action of the one-way threaded rod.

[0010] Preferably, the limiting shaft passes through the interior of the mounting base, and the mounting base and the support platform are respectively provided with fixing grooves, and the two fixing grooves correspond to each other.

[0014] Preferably, the support mechanism includes a connecting seat, which is fixedly connected to the right side of the support platform.

[0017] Compared with the prior art, this utility model provides a device for three-dimensional spatial analysis of urban planning, which has the following beneficial effects:

[0018] 1. This device for 3D spatial analysis in urban planning, through its adjustable mechanism, allows for 3D spatial analysis using a 3D model projector during urban planning. First, the support platform is slidably connected to the top of the mounting base and fixed by a limiting shaft, ensuring the stability of the protective box and the 3D model projector. The device is equipped with casters at the bottom, allowing users to easily move it between different locations. A first servo motor drives a unidirectional threaded rod to rotate, moving the mobile frame up and down along the load-bearing frame, thus achieving precise height adjustment of the mounting base, support platform, and protective box. A second servo motor drives a rotating rod and rotating block to rotate, allowing for angle adjustment of the protective box and the 3D model projector inside, ensuring optimal projection in various spatial environments. Inside the protective box, the bidirectional threaded rod, connecting frame, and limiting frame work together to securely fix the 3D model projector, facilitating installation and disassembly. When the protective box is no longer needed on top of the load-bearing frame and can be moved to another convenient location, simply removing the limiting shaft releases the constraint on the support platform, improving its versatility and applicability.

[0019] 2. This device for three-dimensional spatial analysis in urban planning, through its support mechanism, allows for stable support when the 3D model projector is not used on top of the load-bearing frame but can be moved to another location for convenient use. The connecting seat, rectangular frame, moving shaft, and support plate together form a stable support structure. By adjusting the position of the moving shaft within the rectangular frame and fixing it with limit pins, the position of the support plate can be adjusted according to actual needs. This ensures the stability of the protective box while allowing the height of the 3D model projector to be adjusted as needed. Attached Figure Description

[0031] This utility model provides the following technical solution:

[0032] Example 1

[0033] Please see Figure 1-7 This utility model provides a technical solution: a device for three-dimensional spatial analysis of urban planning, including a support platform 1, an adjustment mechanism 2 on the top of the support platform 1, a support mechanism 3 on the right side of the adjustment mechanism 2, and casters 4 fixedly connected to the bottom of the support platform 1.

[0034] The adjustment mechanism 2 includes a load-bearing frame 21, which is fixedly connected to the top of the load-bearing platform 1. A first servo motor 22 is fixedly connected to the bottom of the load-bearing frame 21. A one-way threaded rod 23 is fixedly connected to the top of the first servo motor 22. A movable frame 24 is connected to the periphery of the one-way threaded rod 23. A mounting base 25 is fixedly connected to the top of the movable frame 24. A support platform 27 is slidably connected to the top of the mounting base 25. A limit shaft 26 is threadedly connected inside the support platform 27. A second servo motor 28 is fixedly connected to the right side of the support platform 27. A rotating rod 291 is fixedly connected to the left side of the second servo motor 28. A rotating block 292 is fixedly connected to the outer periphery of the rotating rod 291. A protective box 29 is fixedly connected to the top of the rotating block 292. A three-dimensional model projector 293 is installed inside the protective box 29. A fixed frame 294 is fixedly connected to the top of the protective box 29. A bidirectional threaded rod 295 is rotatably connected inside the fixed frame 294. A rotating disk 296 is fixedly connected to the right side of the bidirectional threaded rod 295. A connecting frame 297 is threadedly connected to the outer periphery of the bidirectional threaded rod 295. A limit frame 298 is fixedly connected to the left side of the bottom of the connecting frame 297. The limit frame 298 is located to the right of the three-dimensional model projector 293.

[0035] The top of the one-way threaded rod 23 is rotatably connected to the top of the load-bearing frame 21, and the movable frame 24 is slidably connected to the inside of the load-bearing frame 21, so that the movable frame 24 can be moved under the action of the one-way threaded rod 23. The limiting shaft 26 passes through the inside of the mounting base 25. The mounting base 25 and the support platform 27 are respectively provided with fixing grooves, and the two fixing grooves correspond to each other. The limiting shaft 26 is threaded into the fixing groove, so that the support platform 27 can be fixed under the action of the limiting shaft 26.

[0036] The rotating rod 291 is rotatably connected to the inside of the support platform 27 on the left side. The connecting frame 297 is slidably connected to the inside of the fixed frame 294. The limiting frame 298 is slidably connected to the inside of the protective box 29, which facilitates the fixation of the 3D model projector 293 under the action of the limiting frame 298. The bottom of the 3D model projector 293 is in contact with the bottom of the protective box 29. The inside of the limiting frame 298 is in contact with the right side of the 3D model projector 293. The inside of the limiting frame 298 is provided with a rubber pad, which facilitates the stability of the 3D model projector 293 through the limiting frame 298. A wiring groove is opened on the rear side of the protective box 29. The wiring groove is rectangular, which facilitates the connection of external connection cables to the 3D model projector 293 through the wiring groove.

[0037] Example 2

[0038] Please see Figure 1-7 Furthermore, based on Embodiment 1, the support mechanism 3 further includes a connecting seat 31, which is fixedly connected to the right side of the support platform 27. A rectangular frame 32 is fixedly connected to the right side of the connecting seat 31. A movable shaft 34 is slidably connected inside the rectangular frame 32. A support plate 35 is fixedly connected to the bottom of the movable shaft 34. A limit pin 33 is threadedly connected inside the movable shaft 34.

[0039] The limiting pin 33 extends through the interior of the rectangular frame 32 on the left side. Limiting grooves are respectively opened inside the rectangular frame 32 and the moving shaft 34, and the two limiting grooves correspond to each other. The limiting pin 33 is threaded into the limiting groove, which facilitates the stability of the moving shaft 34 under the action of the limiting pin 33. Two sets of connecting seats 31, rectangular frames 32, limiting pins 33, moving shafts 34 and support plates 35 are provided. The two sets of connecting seats 31, rectangular frames 32, limiting pins 33, moving shafts 34 and support plates 35 are symmetrically located on the left and right sides of the support platform 27, which facilitates the stability of the support platform 27 when it is placed in other flat positions.

[0040] In actual operation, when this device is used, and when three-dimensional spatial analysis is required by projecting the three-dimensional model projector 293 during urban planning, the support platform 27 is first slidably connected to the top of the mounting base 25 and fixed by the limiting shaft 26, which can ensure the stability of the protective box 29 and the three-dimensional model projector 293. The bottom of the device is equipped with casters 4, which allows the user to easily push the device and move it flexibly between different sites. When it is moved to the designated position by the casters 4, it can be fixed by the self-locking structure of the casters 4 to ensure the stability of the casters 4.

[0041] Place the 3D model projector 293 in the middle of the bottom of the protective box 29. Rotate the rotating disk 296 to move the bidirectional threaded rod 295, which in turn moves the connecting frame 297 and the limiting frame 298. This causes the moving frame 24 and the limiting frame 298 to move inside the fixed frame 294 and the protective box 29, respectively. This makes the inner side of the limiting frame 298 contact the right side of the 3D model projector 293. The rubber pad on the inner side of the limiting frame 298 can prevent the projector from being damaged by collision during the movement or adjustment of the device, and also enhances the stability of the fixation. Once the fixation is complete, the external connection cable can be connected to the 3D model projector 293 through the wiring groove on the back of the protective box 29.

[0042] During the use of the 3D model projector 293, the first servo motor 22 drives the movable frame 24 connected to the outer thread of the one-way threaded rod 23 to move, thereby adjusting the height of the 3D model projector 293. At the same time, the second servo motor 28 drives the rotating rod 291 and the rotating block 292 to rotate, so that the protective box 29 and the 3D model projector 293 inside it can be angled, thereby ensuring that the 3D model projector 293 can project the best effect in different spatial environments.

[0043] When the 3D model projector 293 is not needed on top of the load-bearing frame 21 and can be used in another convenient location, simply remove the limiting shaft 26 to release the limiting on the support platform 27, allowing the bottom of the support plate 35 to contact the flat surface of the usage location, thus ensuring the stability of the protective box 29. The connecting seat 31, rectangular frame 32, moving shaft 34, and support plate 35 together form a stable support structure. By adjusting the position of the moving shaft 34 within the rectangular frame 32 and fixing it with the limiting pin 33, the position of the support plate 35 can be adjusted according to actual needs. This ensures the stability of the protective box 29 while allowing the height of the 3D model projector 293 to be adjusted according to usage needs. The positions moved by the two sets of moving shafts 34 can correspond to the number of downward movements of the limiting groove.

[0044] The 3D model projector used in this case is model number 293: VPL-EW575.
