Description

Technical Field

[0001] The present invention relates to the field of power plant operation assistance, in particular to a mounting device for a laser scanner. Background Art

[0002] Laser scanners utilize high-speed laser scanning to rapidly acquire coordinates, reflectivity, color, and other data from every point on an object's surface over a large area with high resolution. This provides a novel technology for rapidly reconstructing 1:1 true-color 3D point cloud models. Laser scanners can rapidly scan coal yards, acquiring 3D shape and volume data of coal piles. This allows for precise measurement of coal inventory and improves the efficiency and accuracy of fuel management. Laser scanners scan coal yards regularly. In addition to inventorying coal quantities, they can also monitor environmental conditions in coal yards, such as the stability of coal piles and the presence of spontaneous combustion hazards. When laser scanners are used to assist with coal pile management, a single scan position often fails to cover the entire surface of the object being scanned. This is particularly true for large coal piles, which may be subject to obstruction and blind spots. By performing multiple scans at different locations, data can be acquired from multiple angles, ensuring the integrity of the model.

[0003] However, when coal is transported in or out of the coal storage area, a large amount of coal ash is often generated on site. The coal ash particles suspended in the air will affect the accuracy of the scan data. In addition, the coal ash may adhere to the scanner's lens or sensor, blocking the emission and reception of the laser and reducing the scanner's performance. Therefore, the scanner's lens and sensor must be protected when transporting coal in or out. Summary of the Invention

[0026] Reference Figures 1 to 6This embodiment provides a mounting device for a laser scanner, comprising a movable guide rail 1. Before installing a scanner 3, the movable guide rail 1 is first installed around the walls of a coal pile. A mounting member 2 is provided on top of the movable guide rail 1, and a scanner 3 is provided on top of the mounting member 2. The scanner 3 can move along the movable guide rail 1 along with the mounting member 2. The scanner 3 can move around the coal pile and perform multi-angle scanning around the coal pile, thereby preventing blind spots and ensuring more accurate scanning results.

[0027] The mounting component 2 includes a moving mechanism 21 arranged inside the moving guide rail 1. The moving mechanism 21 can move along the moving guide rail 1 on the moving guide rail 1. A clamping mechanism 22 is provided on the top of the moving mechanism 21. When installing the scanner 3, the clamping mechanism 22 can quickly install and disassemble the scanner 3. During maintenance, the scanner 3 can be quickly removed, and the scanner 3 can be quickly installed after the maintenance is completed. A protective mechanism 23 is provided on the top of the clamping mechanism 22. When transporting coal into or out of the coal pile, the scanner 3 can be moved to a designated position on the moving guide rail 1, and the protective mechanism 23 will move to the camera or sensor in front of the scanner 3 for shielding and protection to prevent coal ash from contaminating the camera or sensor in front of the scanner 3.

[0028] Furthermore, the movable guide rail 1 includes a circular track 11, and a block 12 is provided on the top of the circular track 11. Preferably, the block 12 is only provided at a specific position on the circular track 11. When the moving mechanism 21 moves with the scanner 3 to the block 12 on the track, the protective mechanism 23 will protect the scanner 3. Of course, when the scanner 3 moves to this position, the camera and sensor on the front of it will be blocked, and the scanning will be disturbed.

[0029] Furthermore, the mobile mechanism 21 includes a mobile frame 211 arranged inside the circular track 11, a driving wheel 212 is provided on the bottom side of the mobile frame 211, and a driven wheel 213 is provided on the side of the mobile frame 211 away from the driving wheel 212. The driving wheel 212 is a driving wheel, which has a built-in motor or a motor is provided on the mobile frame 211, which drives the driving wheel to rotate and drives the entire mobile mechanism 21 to move on the moving guide rail 1.

[0030] Usage process: After installing the movable guide rail 1 around the coal pile on the four walls of the coal pile site, install the mounting component 2 on the movable guide rail 1, and then install the scanner 3 on the mounting component 2. When the movable mechanism 21 moves around the coal pile on the guide rail, the movable mechanism 21 will rotate with the scanner 3. The scanner 3 can scan the coal pile at multiple angles around the coal pile, thereby improving the scanning accuracy and the scanning quality. When transporting coal into or out of the coal pile site, the scanner 3 can move to the location of the block 12 on the movable guide rail 1. At this time, the protective mechanism 23 will move to the camera or sensor in front of the scanner 3 for shielding and protection.

[0031] Example 2, reference Figures 1 to 6 , which is the second embodiment of the present invention, is different from the previous embodiment in that the clamping mechanism 22 includes a clamping base plate 221 arranged on the top of the mobile frame 211, as shown in FIG. Figure 3 As shown, the bottom of the clamping base 221 is fixedly connected to the mobile frame 211, and a receiving groove 222 is provided inside the clamping base 221. A wedge strip 223 is provided inside the receiving groove 222. The wedge strip 223 can slide horizontally in the receiving groove 222. One end of the wedge strip 223 extending into the receiving groove 222 is set in a wedge shape. A pull block 224 is provided on the side of the wedge strip 223. The pull block 224 is fixedly connected to the wedge strip 223. The pull block 224 is set on the clamping base 221 On the outside, a limiting block 225 is provided at the bottom of the wedge strip 223, and a first elastic member 226 is provided on the side of the limiting block 225. The end of the first elastic member 226 away from the limiting block 225 is connected to the inner wall of the accommodating groove 222, and the first elastic member 226 is in a compressed state. A clamp 227 is provided on the top of the clamping base plate 221, and the clamp 227 is fixedly connected to the clamping base plate 221 through a connecting member. A clamping seat 229 is provided on the top of the clamping base plate 221.

[0032] Furthermore, the clamping seat 229 includes a support plate 2291 disposed above the clamping base plate 221, and a hook block 2292 is disposed at the bottom of the support plate 2291. Figure 3As shown, the hook block 2292 is arranged inside the accommodating groove 222, and the hook block 2292 can slide up and down inside the accommodating groove 222. The side of the hook block 2292 is provided with a wedge-shaped protrusion, and the wedge-shaped protrusion cooperates with the wedge bar 223. The outer side of the abutment plate 2291 is provided with an elastic clamping plate 2293, and there are multiple elastic clamping plates 2293. The elastic clamping plates 2293 are arranged in a circular array around the outer edge of the bottom plate, and the bottom of the abutment plate 2291 is provided with a clamping column 2294, and the bottom outer edge of the clamping column 2294 is provided with a circular protrusion. The top of the clamping base plate 221 is provided with a step groove 228, and the bottom of the clamping column 2294 is provided inside the step groove 228. The clamping column 2294 is clamped inside the step groove 228, and the clamping column 2294 can slide up and down inside the step groove 228, but cannot be separated from the step groove 228.

[0033] When the scanner 3 is installed, the bottom of the scanner 3 is pressed against the plate 2291, and the scanner 3 is pressed downward, which will drive the plate 2291 to slide downward, so that the hook block 2292 slides downward, and the hook block 2292 squeezes the wedge strip 223 outward. At the same time, the elastic splint 2293 moves downward relative to the clamp 227, and the elastic splint 2293 moves toward the center of the plate 2291 under the squeezing action of the clamp 227. The elastic splints 2293 are close to each other, and the elastic splint 2293 clamps the scanner 3. At the same time, the wedge-shaped protrusion of the hook block 2292 moves to the bottom of the wedge strip 223. At this time, the wedge strip 223 moves toward the hook block 2291 under the action of the first elastic member 226. The wedge bar 223 is then moved away from the hook block 2292 so that the wedge bar 223 can be moved away from the hook block 2292. The elastic splint 2293 can then be pressed downward to press the clamp 227. The elastic splint 2293 can then slide upward relative to the clamp 227. The distance between the elastic splints 2293 can increase, and the scanner 3 can no longer be clamped. The scanner 3 can be easily removed, and the clamping mechanism 22 can quickly install and disassemble the scanner 3, saving time when maintaining the scanner 3.

[0034] Example 3, reference Figures 1 to 6 , which is the third embodiment of the present invention. Different from the previous embodiment, the protective mechanism 23 includes a connecting frame 231 arranged on the side of the clamping base plate 221, and an intermediate card plate 232 is provided on the side of the connecting frame 231. Second elastic members 233 are provided on both sides of the intermediate card plate 232. The end of the second elastic member 233 away from the intermediate card plate 232 is connected to the clamping base plate 221, and the second elastic member 233 is in a compressed state. A protective plate 234 is provided on the top of the connecting frame 231.

[0035] Furthermore, the number of the protective plates 234 is multiple, and the multiple protective plates 234 are arranged in parallel on the outside of the scanner 3. A connecting pin 235 is provided between adjacent protective plates 234, and the connecting pin 235 can slide on the protective plates 234. The outer wall of the connecting pin 235 is provided with a third elastic member 236. A circular groove 237 is opened on the side of the protective plate 234, and the top and bottom ends of the third elastic member 236 are arranged in the circular groove 237. Figure 4 As shown, preferably, the protective plate 234 is a metal plate with high thermal conductivity. In normal state, the third elastic member 236 creates a gap between adjacent protective plates 234, which helps air flow on the surface of the scanner 3 and helps dissipate heat from the scanner 3.

[0036] Furthermore, a bottom rod 238 is provided at the bottom of the connecting frame 231, and a rotating block 239 is provided at one end of the bottom rod 238 away from the connecting frame 231. The top of the rotating block 239 is connected to the clamping base plate 221, and the rotating block 239 is rotatably connected to the clamping base plate 221. The rotating block 239 can rotate at the bottom of the clamping base plate 221. A shift lever 240 is provided on the side of the rotating block 239 away from the bottom rod 238. A limiting ring 31 is provided at the top of the scanner 3, and a guide arc plate 32 is provided at the bottom of the limiting ring 31. Figure 4 As shown, the limiting ring 31 is located on the top outer wall of the scanner 3 , the limiting ring 31 is fixedly connected to the scanner 3 , the bottom of the limiting ring 31 is fixedly connected to the guide arc plate 32 , and another guide arc plate 32 is also provided on the outer side of the middle part of the scanner 3 .

[0037] Usage process: When the scanner 3 moves along the guide rail and scans the coal pile on the guide rail, there is a gap between the adjacent protective plates 234. When coal is transported into or out of the coal pile and coal ash is generated, the scanner 3 moves to the block 12, such as Figure 6As shown, under the action of the card block 12, the lever 240 will be squeezed by the card block 12, and the lever 240 will drive the rotating block 239 to rotate, driving the bottom rod 238 and the connecting frame 231 to rotate together. The rotation of the connecting frame 231 will drive the protective plate 234 to move toward the camera on the front of the scanner 3, and the protective plate 234 will move between the two guide arc plates 32. The protective plates 234 will be squeezed by the upper and lower guide arc plates 32 and will move closer to each other. The adjacent protective plates 234 will be close together, and the third elastic member 236 will be compressed. The third elastic member 236 is squeezed into the circular groove 237, and the space between the protective plates 234 There is no gap. The protective plate 234 blocks the camera and sensor in the middle of the front of the scanner 3 to prevent coal dust from adhering to the scanning elements and causing pollution. After waiting for the coal dust to dissipate, the scanner 3 continues to move away from the location of the card block 12. The third elastic member 236 will push the middle card plate 232 toward the middle. The middle card plate 232 will drive the connecting frame 231 to move and drive the protective plate 234 to separate from the guide arc plate 32. Then, under the action of the second elastic member 233, adjacent protective plates 234 will move away from each other and surround the outside of the scanner 3 again. There are gaps between adjacent protective plates 234, which is conducive to heat dissipation.

[0038] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
