Description

Technical Field

[0001] This utility model belongs to the field of image processing and computer vision technology, and relates to a substation modeling device for point cloud data. Background Technology

[0002] With the continuous advancement of smart grid construction, substations, as key hubs in the power system, face increasingly urgent demands for refined management. To achieve efficient monitoring of substation equipment status, precise formulation of operation and maintenance plans, and rapid emergency response, creating 3D models of substations has become an important method. 3D modeling can intuitively present the spatial layout, equipment structure, and operating status of substations, providing strong support for the safe and stable operation of the power system.

[0003] Currently, in the process of 3D modeling of substations, point cloud data is usually obtained by scanning on-site. In actual operation, staff often need to use handheld modeling scanners to collect data. However, many devices in substations, such as transformers, high-voltage circuit breakers, and surge arresters, are generally installed at high positions, making it difficult for staff to directly scan them. This not only presents inconvenience but also poses safety hazards due to working at heights. It also leads to low data collection efficiency and insufficient data integrity, affecting the quality and effect of 3D modeling and thus hindering practical use. Utility Model Content

[0025] Example 1

[0026] like Figures 1 to 8As shown, the scanner body 1 includes a mounting shell 2 at its top and bottom. Connecting plates 3 are movably connected to the outer walls of the mounting shell 2 on both sides. The connecting plates 3 are fixedly connected to the scanner body 1. A vertical tube 4 is provided below the scanner body 1. A mounting plate 5 is fixedly connected to the side wall of the vertical tube 4 near the top. One side of the mounting plate 5 extends into the mounting shell 2. Mounting mechanisms are provided at the top and bottom of the scanner body 1 to fix the position of the vertical tube 4. An extension rod 15 is slidably connected to the inner wall of the vertical tube 4. The bottom end of the extension rod 15 extends to the bottom of the vertical tube 4 and is fixedly connected to a base plate 16. A connecting mechanism is provided on the base plate 16. The base plate 16 is H-shaped and is used to connect with the landing gear of the UAV. A threaded hole 23 is opened on the side wall of the vertical tube 4. A bolt 24 is installed in the threaded hole 23. One end of the bolt 24 extends into the vertical tube 4 and contacts the extension rod 15. A pad 22 is fixedly connected to the top and bottom of the scanner body 1 and contacts the top of the vertical tube 4.

[0027] like Figure 4 and Figure 7 As shown, the mounting mechanism includes a fixing plate 6. The top and bottom of the scanner body 1 are fixedly connected to the fixing plate 6. A square hole 7 is opened on one side of the fixing plate 6. A positioning rod 8 is installed in the square hole 7. Both ends of the positioning rod 8 extend to the outside of the square hole 7. A locking block 14 is fixedly connected to the side wall of the vertical tube 4 near the top. The locking block 14 is located inside the positioning rod 8. A circular plate 10 is fixedly connected to the side wall of the positioning rod 8. A circular ring 11 is sleeved on the side wall of the positioning rod 8. A support plate 12 is fixedly connected to the side wall of the circular ring 11. One end of the support plate 12 is fixedly connected to the scanner body 1. A first spring 9 is sleeved on the side wall of the positioning rod 8. One end of the first spring 9 is fixedly connected to the circular plate 10, and the other end is fixedly connected to the circular ring 11. A pull ring 13 is fixedly connected to one end of the positioning rod 8.

[0028] The vertical tube 4 can be easily disassembled and installed through the installation mechanism, and the vertical tube 4 will not wobble after installation. The pad 22 can reduce the gap between the vertical tube 4 and the scanner body 1, so that it will not wobble during use. In addition, the vertical tube 4 can be installed on the top or bottom of the scanner body 1 as needed, and the scanning height can be increased by the pull-out extension rod 15. The scanner body 1 in this technical solution is a portable 3D scanner in the prior art, which is a relatively mature technology. Its working principle and practical method are common knowledge among those in the field, so they will not be described in detail in this technical solution.

[0029] Example 2

[0030] like Figures 1 to 8As shown, the connecting mechanism includes a hanging plate 17. The hanging plate 17 is symmetrically and movably connected between the inner walls of the two sides of the base plate 16. One end of the hanging plate 17 is provided with an arc-shaped hook. A rectangular opening 19 is opened on one side of the hanging plate 17. A rectangular block 20 is slidably connected between the inner walls of the two sides of the rectangular opening 19. A movable plate 18 is fixedly connected to one side of the rectangular block 20 to the outside of the rectangular opening 19. One end of the movable plate 18 is provided with an arc. A second spring 21 is fixedly connected between the bottom of the rectangular block 20 and the bottom of the inner cavity of the rectangular opening 19.

[0031] The scanner body 1 can be mounted on the landing gear of the drone or other suitable parts through the connection mechanism, and the stability of the connection is improved. In this way, the drone can carry the scanner body 1 to the place where it is needed to scan the device. The inner wall of the arc-shaped hook on the mounting plate 17 can be equipped with anti-slip pads or magnetic sheets to improve the stability of the connection and avoid slippage that would cause the drone to become unstable.

[0032] Among them, sliders are fixedly connected to the two sides of the rectangular block 20 that are opposite to the inner wall of the rectangular opening 19. The inner wall of the rectangular opening 19 is provided with a sliding groove that matches the slider. The slider and the sliding groove can limit the rectangular block 20 so that the rectangular block 20 will not rotate when sliding, thereby keeping the movable plate 18 and the hanging plate 17 parallel.

[0033] Working Principle: In use, if the scanner body 1 is used, the scanning height can be increased by installing the vertical tube 4. First, the mounting plate 5 on the vertical tube 4 is inserted into the mounting shell 2. After the mounting plate 5 is fully inserted into the mounting shell 2, the vertical tube 4 is pushed to swing to a vertical position. When the vertical tube 4 is in a vertical position, the locking block 14 on the vertical tube 4 will push the positioning rod 8 outward to compress the first spring 9. When the vertical tube 4 is completely vertical, the locking block 14 is located between the positioning rod 8 and the scanner body 1, so that the top of the vertical tube 4 is in complete contact with the pad 22. Simultaneously, the first spring 9 rebounds and pushes... The moving circular plate 10 and the positioning rod 8 return to their initial positions, which can block the locking block 14 and thus fix the vertical tube 4. This allows the scanner body 1 to be raised during use. If necessary, the extension rod 15 can be pulled out to extend the height. First, loosen the bolt 24 and then pull out the extension rod 15. After pulling the extension rod 15 to the appropriate length, tighten the bolt 24. The position of the extension rod 15 is fixed by the compression of the bolt 24. In this way, the scanner body 1 can be lifted to a higher position by the extended vertical tube 4 and the extension rod 15, so that the staff can scan the equipment at a higher position.

[0034] When encountering equipment installed at a high position, or when it is inconvenient for staff to reach the equipment location, a remote-controlled drone using existing technology can be used. First, by pulling the positioning rod 8 with the pull ring 13, the circular plate 10 is compressed against the first spring 9, causing the positioning rod 8 to move outward. This allows the locking block 14 on the vertical tube 4 to swing out of the positioning rod 8. Then, the mounting plate 5 can be pulled out and inserted into the mounting shell 2 on the upper side of the scanner body 1. After the above operation, the vertical tube 4 is installed on the top of the scanner body 1. Next, by pulling the movable plate 18, the second spring 21 is compressed, causing the hook of the hanging plate 17 to open, and the hanging plate 17 is hung on the drone. The landing gear or other suitable parts of the human-machine interface are then attached, and the movable plate 18 is released. Simultaneously, the rebound force of the second spring 21 pushes the rectangular block 20 and the movable plate 18 back to the initial position, closing the hook of the hanging plate 17. This improves the stability and safety of the suspension. After the two hanging plates 17 are attached to the drone, the drone can be controlled to move the lifting scanner body 1 to the required position for scanning. This effectively solves the problem that a large number of devices in the power station are generally installed at high positions, making it difficult for staff to directly scan them. This not only causes inconvenience in operation but also poses safety hazards due to working at height.

[0035] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
