Description

Technical Field

[0001] This utility model relates to the field of mobile measurement technology for sand transport vessels, specifically a mobile measurement device used on sand transport vessels. Background Technology

[0002] Sand is a crucial filling material in dredging and backfilling projects. Large quantities of sand are transported to the filling site by waterway via sand-carrying vessels. Due to the high unit price of each cubic meter of sand, it constitutes a significant portion of the project cost. Therefore, rapid and accurate measurement is critical, as the sand volume significantly impacts project management and volume measurement. Traditional manual measurement with measuring tapes is slow, prone to errors, difficult to perform at night, and requires a large workforce, failing to meet on-site construction needs. Thus, how to quickly and accurately measure the sand volume of sand-carrying vessels is a pressing problem. To achieve the goals of accurate volume measurement during construction, facilitating project production management, saving costs, and accurately calculating requirements, handheld 3D laser scanning measurement technology offers advantages such as speed, flexibility, high ground resolution, portability, and multi-view capabilities. By installing an automatic volume measurement system on the sand-carrying vessel, surveyors can conveniently mount a handheld 3D laser scanner directly onto the device for equipment debugging. By setting the device's trajectory, the 3D laser scanner can move unattended, ultimately completing the entire measurement process. However, many mobile measurement devices are directly installed, requiring the 3D laser scanner to be directly mounted on the device, which is too cumbersome. In addition, due to environmental factors, such as wind, waves, or heavy rain, staff cannot disassemble the mobile measurement device in time, making it prone to damage.

[0003] Based on this, a mobile measuring device for use on sand transport vessels is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this utility model is to provide a mobile measuring device for use on sand transport vessels, so as to solve the problem that the installation or disassembly of mobile measuring devices in the prior art is too troublesome.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A mobile measuring device for use on a sand transport vessel includes a mobile measuring device, a three-dimensional laser scanner fixedly connected to the top of the mobile measuring device, a moving mechanism for moving the mobile measuring device provided on the surface of the passageway above the sand hopper, a connecting mechanism for installing or disassembling the measuring device provided at the bottom of the mobile measuring device, and a measuring mechanism for performing mobile measurements provided inside the three-dimensional laser scanner.

The bottom of the moving measuring device is fixedly connected to the connecting sleeve. A limiting groove is formed on the surface of the connecting sleeve. A spring groove is formed on one side of the inner wall of the limiting groove. A spring is provided inside the spring groove. One end of the spring is fixedly connected to the spring groove, and the other end is fixedly connected to the locking pin. Threaded rods are threadedly connected to both sides of the connecting sleeve. A rotating block is fixedly connected to one end of the threaded rod. A locking slot is formed on one side of the limiting block, and one end of the locking pin cooperates with the locking slot.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model utilizes a connecting mechanism. When the moving measuring device needs to be installed, the connecting sleeve is connected to the limiting block via the limiting groove, allowing the moving measuring device to be connected to the limiting block via the connecting sleeve. Then, the rotating block is turned to thread one end of the threaded rod onto the limiting block, fixing the moving measuring device to the limiting block via the connecting sleeve.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-6As shown, a mobile measuring device used on a sand transport vessel includes a mobile measuring device 4. A three-dimensional laser scanner 5 is fixedly connected to the top of the mobile measuring device 4. It adopts a high-density underwater three-dimensional laser point cloud to quickly acquire high-precision positioning and attitude data during the movement of the sand transport vessel. The surface of the passageway 1 above the sand hopper is provided with a moving mechanism 2 for moving the mobile measuring device 4, so that the mobile measuring device 4 can move automatically. The bottom of the mobile measuring device 4 is provided with a connecting mechanism 3 for installing or disassembling the measuring device, so as to facilitate the installation or disassembly of the mobile measuring device 4. The interior of the three-dimensional laser scanner 5 is provided with a measuring mechanism 7 for moving measurement, which can perform precise measurements.

[0026] In one embodiment, such as Figure 1 - Figure 3 As shown, the moving mechanism 2 includes a fixed support 201, a slide rail base 202, a slide rail 203, a positioning ball 204, a fixing plate 205, a limiting block 206, a threaded hole 207, and bolts 208. Multiple sets of fixed supports 201 are fixedly connected to one side of the passageway 1 above the sand chamber. A slide rail base 202 is fixedly connected to one side of each fixed support 201. A slide rail 203 is provided on the surface of the slide rail base 202. Positioning balls 204 are fixedly connected to both ends of the fixed supports 201 to determine the measurement boundary of the three-dimensional laser scanner 5 on the moving measuring device 4. The top of the slide rail 203 is provided with a fixing plate 205. The top of the fixing plate 205 is fixedly connected to a limit block 206. Multiple sets of threaded holes 207 are opened at both ends of the fixing plate 205. Bolts 208 are threadedly connected to the inner wall of the threaded holes 207. One end of the bolt 208 is engaged with the slide rail 203. The fixing plate 205 is placed on the slide rail 203, and the bolt 208 is tightened. The bolt 208 passes through the threaded hole 207 and is threadedly connected to the slide rail 203, so that the fixing plate 205 is fixed on the slide rail 203 for subsequent installation of the moving measuring device 4.

[0027] In one embodiment, such as Figure 4As shown, the connecting mechanism 3 includes a connecting sleeve 301, a limiting groove 302, a spring groove 303, a spring 304, a locking pin 305, a threaded rod 306, a rotating block 307, and a locking groove 308. The bottom of the moving measuring device 4 is fixedly connected to the connecting sleeve 301. The surface of the connecting sleeve 301 is provided with a limiting groove 302. A spring groove 303 is provided on one side of the inner wall of the limiting groove 302. A spring 304 is provided inside the spring groove 303. One end of the spring 304 is fixedly connected to... The connecting sleeve 301 has a spring groove 303 at one end and a locking pin 305 fixedly connected at the other end. Threaded rods 306 are threaded onto both sides of the connecting sleeve 301. A rotating block 307 is fixedly connected to one end of the threaded rod 306. A locking groove 308 is provided on one side of the limiting block 206, and one end of the locking pin 305 engages with the locking groove 308. When the moving measuring device 4 needs to be installed, the connecting sleeve 301 is connected to the limiting block 206 through the limiting groove 302, allowing the limiting block 206 to insert... In the limiting groove 302, the surface of the limiting block 206 will press the locking pin 305 and the spring 304. When the limiting block 206 is in the correct position, the spring 304 resets and pushes the locking pin 305 into the inside of the slot 308, so that the moving measuring device 4 is connected to the limiting block 206 through the connecting sleeve 301. Then, the rotating block 307 is turned so that one end of the threaded rod 306 is threadedly connected to the limiting block 206, so that the moving measuring device 4 is fixed to the limiting block 206 through the connecting sleeve 301, which facilitates the installation of the moving measuring device 4. When it is necessary to disassemble the moving measuring device 4, the rotating block 307 is turned off so that the threaded rod 306 is moved out of the limiting block 206, so that the moving measuring device 4 can be pulled out from the moving mechanism 2 through the connecting sleeve 301, which facilitates the disassembly of the moving measuring device 4 and avoids damage to the moving measuring device 4 when there are winds, waves or heavy rains.

[0028] In one embodiment, such as Figure 4 As shown, the inner wall size of the limiting groove 302 matches the outer wall size of the limiting block 206. When the limiting block 206 slides inside the limiting groove 302, the limiting groove 302 can limit the sliding of the limiting block 206 and prevent the limiting block 206 from shaking inside the limiting groove 302.

[0029] In one embodiment, such as Figure 6 As shown, the diameter of the spring groove 303 matches the diameter of the spring 304. When the spring 304 extends or retracts, the spring groove 303 will limit the spring 304 to prevent the spring 304 from shaking.

[0030] In one embodiment, such as Figure 4 As shown, the surface of the rotating block 307 is provided with multiple sets of protrusions, which can increase the friction with the hand and make it easier to rotate the rotating block 307.

[0031] In one embodiment, such as Figure 5 As shown, the measuring mechanism 7 includes a drive motor 701, a connecting rod 702, and a measuring scanner 703. The drive motor 701 is fixedly connected inside the 3D laser scanner 5. One end of the drive motor 701 is fixedly connected to the connecting rod 702, and the other end of the connecting rod 702 is fixedly connected to the measuring scanner 703. When measuring, the drive motor 701 is started, and the drive motor 701 drives the connecting rod 702 to rotate. When the connecting rod 702 rotates, it can drive the measuring scanner 703 to rotate, so as to measure the sand in the sand tank, thereby facilitating the completion of the measurement task of sand transported by a single ship.

[0032] In one embodiment, such as Figure 2 As shown, the surface of the 3D laser scanner 5 is equipped with multiple panoramic cameras 6, which can display high-definition panoramic images of the sand hold inside the sand transport ship in real time, and can observe the status inside the sand hold in a timely manner.

[0033] Working Principle: The above embodiment discloses a mobile measuring device used on a sand transport vessel. In use, the fixing plate 205 is placed on the slide rail 203, and the bolt 208 is tightened. The bolt 208 passes through the threaded hole 207 and is threadedly connected to the slide rail 203, fixing the fixing plate 205 to the slide rail 203 for subsequent installation of the mobile measuring device 4. When the mobile measuring device 4 needs to be installed, the connecting sleeve 301 is connected to the limiting block 206 through the limiting groove 302, so that the limiting block 206 is inserted into the limiting groove 302. The surface of the limiting block 206 will press against the locking pin 305 and the spring 304. When the limiting block 206 is in the correct position, the spring 304 resets and pushes the locking pin 305 into the groove 308, connecting the mobile measuring device 4 to the limiting block 206 through the connecting sleeve 301. Then, the rotating block 307 is tightened, causing one end of the threaded rod 306 to be threadedly connected to the limiting block 206. The moving measuring device 4 is fixed to the limiting block 206 via the connecting sleeve 301, which facilitates the installation of the moving measuring device 4. When it is necessary to disassemble the moving measuring device 4, the rotating block 307 is unscrewed, and the threaded rod 306 is moved out of the limiting block 206, so that the moving measuring device 4 can be pulled out from the moving mechanism 2 via the connecting sleeve 301, which facilitates the disassembly of the moving measuring device 4. This avoids the inability of the staff to disassemble the moving measuring device 4 in time during wind, waves, or heavy rain, which could damage the moving measuring device 4. When measuring, the drive motor 701 is started, which drives the connecting rod 702 to rotate. When the connecting rod 702 rotates, it can drive the measuring scanner 703 to rotate. The moving measuring device 4 can be moved left and right via the slide rail 203 on the slide rail base 202, so as to measure the sand in the sand tank, thus facilitating the completion of the sand measurement task for a single ship transport.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
