Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering surveying equipment technology, and in particular to an auxiliary device integrating a surveying unmanned vessel and a handheld scanner. Background Technology
[0002] The emergence of unmanned survey vessels has effectively solved practical problems in waterborne surveying operations. With the development of science and technology, unmanned detection systems are developing towards intelligence, diversification, and integration.
[0003] 3D scanning technology was developed to meet the design and manufacturing requirements of industrial fields. Its mainstream technology has evolved to its fourth generation since its inception. The first generation was contact measurement technology, the second was line laser scanning technology, and the third was structured light scanning technology. Compared with the first two generations, the third generation technology has significantly improved in efficiency, cost, and usability, thus leading to its rapid global adoption. However, these two advanced technologies are not interconnected, making it impossible to meet the need for simultaneous underwater and surface topographic measurements.
[0004] The existing technical solutions mentioned above have the following drawbacks: current unmanned vessels can only conduct underwater measurements and cannot measure the topography and landforms on both sides of the river; handheld surveying scanners can only measure ground objects and cannot measure the elevation and topography of water areas. The separation of these two types of data leads to low surveying efficiency and high costs, and personnel must wade through water to work, resulting in significant safety risks. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide an auxiliary device integrating a surveying unmanned surface vessel (USV) and a handheld scanner. This modular connection device solves the problem of fragmented equipment functions, enabling integrated surveying both above and below water, and reducing safety risks and operating costs. Designed to meet the needs of integrated operations, reduce river environmental risks, improve data accuracy, and reduce instrument purchases, this invention combines two devices with different uses through a simple auxiliary leveling mechanism, achieving a more cost-effective and efficient solution.
[0006] The above-mentioned utility model objective is achieved through the following technical solution:
[0007] An auxiliary device integrating a measuring unmanned surface vessel and a handheld scanner, comprising:
[0008] The auxiliary platform has two mounting holes in the middle for fixing a handheld measuring scanner, and four through holes around the perimeter.
[0009] The fall-prevention double-threaded support column has threads at both ends, and a fall-prevention device is fixedly connected to one end.
[0010] A fixing nut is used to lock the auxiliary platform and the anti-fall double-threaded support column;
[0011] Screw slots are provided on the edge of the auxiliary platform for adjusting the levelness of the auxiliary platform;
[0012] One end of the anti-fall double-threaded support column is connected to the measuring unmanned vessel through the screw slot, and the other end passes through the auxiliary platform and is fixed by the fixing nut. The handheld measuring scanner is installed in the middle of the auxiliary platform.
[0013] As a further technical solution of this utility model: the fall arrestor is a square metal block with a round hole, which is welded to one end of the fall arrestor double-threaded support column, and the diameter of the round hole matches the diameter of the fall arrestor double-threaded support column.
[0014] As a further technical solution of this utility model: the diameter of the through holes around the auxiliary platform is 0.5cm larger than the diameter of the anti-fall double-threaded support.
[0015] As a further technical solution of this utility model: the diameter of the two mounting holes is 3cm, and the distance between the two mounting holes is ≥10cm.
[0016] As a further technical solution of this utility model: the position of the hull drilling hole of the measuring unmanned vessel corresponds to the position of the through hole of the auxiliary platform, and the hull drilling hole is embedded with a rubber-fixed matching nut.
[0017] In summary, this utility model has at least one of the following beneficial technical effects:
[0018] This utility model discloses an auxiliary device integrating a surveying unmanned surface vessel (USV) and a handheld scanner. It connects the USV to an auxiliary platform with a leveling adjustment slot via a fall-proof double-threaded support, ensuring stable mounting of the handheld scanner. This solves the problem of fragmented topographic data between above-water and underwater surfaces, significantly improving surveying efficiency and safety while reducing operating costs. It also reduces the risks posed to workers by the river environment, meets the requirements for integrated above-water and underwater work, saves time, and, by combining the two devices, increases the utilization rate of older equipment.

Figure 2The screw slot 6 is located on the edge of the auxiliary platform 1 and is used to adjust the level of the auxiliary platform 1. One end of the anti-fall double-threaded support column 3 is connected to the measuring unmanned boat 7 through the screw slot 6, and the other end passes through the auxiliary platform 1 and is fixed by the fixing nut 5. The handheld measuring scanner 2 is installed in the middle of the auxiliary platform 1.
[0030] Reference Figure 5 The fall arrestor 4 is a square metal block with a round hole, which is welded to one end of the fall arrestor double-threaded support 3. The diameter of the round hole matches the diameter of the fall arrestor double-threaded support 3.
[0031] The diameter of the through holes 12 around the auxiliary platform 1 is 0.5 cm larger than the diameter of the anti-fall double-threaded support 3. The diameter of the two mounting holes 11 is 3 cm, and the distance between the two mounting holes 11 is ≥10 cm. The position of the hull drill hole of the unmanned vessel 7 corresponds to the position of the through hole 12 of the auxiliary platform 1, and the hull drill hole is fitted with a rubber-fixed matching nut.
[0032] The installation steps of this utility model are as follows:
[0033] Step 1: First, drill a round hole in the square iron block. The size of the round hole is the same as the diameter of the double-threaded support, forming the fall protection device 4.
[0034] Step 2: Weld the fall arrestor 4 to the threaded end of the double-threaded part and connect it to the smooth part to form a fall arrestor threaded support.
[0035] Step 3: Drill 6 holes in a clamping plate that matches the size of the unmanned vessel's center section. The holes around the perimeter should be 0.5 cm larger than the diameter of the anti-fall threaded support. The two holes in the middle should be approximately 3 cm in diameter, and the distance between the two holes should not be less than 10 cm, to facilitate the subsequent fixing of the handheld measuring scanner 2, forming the auxiliary platform 1.
[0036] Step 4: Drill holes around the unmanned boat 7 (the drilling positions are the same as the drilling positions around the auxiliary platform 1, and the size should be larger than the diameter of the anti-fall thread support). Place the drilled holes into nuts and fix them with special rubber (the nuts should match the threads of the anti-fall thread support).
[0037] Step 5: Drill two holes in the handheld measuring scanner 2 (the holes should be at the same midpoint as described in Step 3, for secure fixing);
[0038] Step 6: First, tighten one end of the anti-fall threaded support without the anti-fall device 4 to the four nut holes of the unmanned boat. Then, install the auxiliary platform 1 onto the anti-fall threaded support and tighten it with the fixing nut 5. Next, install the handheld measuring scanner 2 onto the auxiliary platform 1 and tighten it with the fixing nut 5. This completes the installation process of this new and practical device.
