For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Embodiment 1:

[0034] Please refer to Figures 1 - 9 , the present invention provides a technical solution: a heat dissipation and protection structure for a multi-line scanning laser scanner, including a protective cover 1 and a support plate 2, and a heat dissipation and protection structure is arranged inside the protective cover 1;

[0035] The heat dissipation and protection structure includes a heat dissipation mechanism 3, a protection mechanism 4 and a clamping mechanism 5;

[0036] The heat dissipation mechanism 3 includes a heat dissipation box 301, a dust-proof net 302, a connecting plate 303, a first fixing bolt 304, and a fixing plate 305. The inner wall of the heat dissipation box 301 is in pressing contact with one side of the dust-proof net 302. One side of the dust-proof net 302 is connected to one side of the connecting plate 303. The inner wall of the connecting plate 303 is threadedly connected to the outer wall of the first fixing bolt 304. The inner wall of the heat dissipation box 301 is connected to both ends of the fixing plate 305. A heat dissipation fan 306 is fixedly installed on one side of the fixing plate 305, and a refrigeration device 307 is fixedly installed on the inner wall of the heat dissipation box 301;

[0037] In this embodiment, an air intake groove is provided on one side of the heat dissipation box 301. The number of connecting plates 303 is four, and the connecting plates 303 are symmetrically distributed on one side of the dust-proof net 302 respectively, so that the dust-proof net 302 can be disassembled and assembled quickly and conveniently, and thus can be used better;

[0038] Furthermore, a limiting hole is provided on the inner wall of the heat dissipation box 301. One end of the first fixing bolt 304 is threadedly connected to the inner wall of the limiting hole. The number of heat dissipation fans 306 is five, and the heat dissipation fans 306 are symmetrically distributed on one side of the fixing plate 305 respectively, so that the air inside the heat dissipation box 301 can be quickly and conveniently blown into the protective cover 1, and thus the heat dissipation work of the multi-line scanning laser scanner can be better carried out.

[0039] When in use, the operator places the multi-line scanning laser scanner inside the protective cover 1 and on the placement plate 404, and clamps and fixes the multi-line scanning laser scanner through the clamping mechanism 5. When heat dissipation work is required, starting the refrigeration device 307 can reduce the air temperature inside the heat dissipation box 301. At this time, starting the heat dissipation fan 306 can blow the air inside the heat dissipation box 301 into the protective cover 1, thereby being able to dissipate heat from the multi-line scanning laser scanner. The dust-proof net 302 can filter out impurities in the external air, thus effectively preventing impurities from entering the protective cover 1 and affecting the heat dissipation of the multi-line scanning laser scanner. When the dust-proof net 302 needs to be disassembled, rotate the fixing bolt 1 304 to make it move on the inner wall of the connecting plate 303, and the dust-proof net 302 can be disassembled by the movement of the fixing bolt 1 304. When installation is required, repeat the above steps in reverse to install, which can be more convenient for the operator to use and can better perform heat dissipation work.

[0040] Embodiment 2:

[0041] On the basis of Embodiment 1, the protection mechanism 4 includes a buffer box 401, a buffer plate 402, a buffer rod 403, a placement plate 404, and a damper 405. The two ends of the buffer plate 402 are slidably connected to the inner wall of the buffer box 401. The top of the buffer plate 402 is connected to the bottom of the buffer rod 403. The top of the buffer rod 403 is connected to the bottom of the placement plate 404. The bottom of the placement plate 404 is connected to the top of the damper 405. One side of the buffer box 401 is communicatively provided with an air duct 406. One end of the air duct 406 is communicatively provided with a telescopic airbag 407. One end of the telescopic airbag 407 is fixedly installed with a moving plate 408. A guide rod 1 409 is slidably connected to the inner wall of the moving plate 408. A cleaning brush 410 is fixedly installed on one side of the moving plate 408;

[0042] In this embodiment, the number of buffer boxes 401 is four, and the buffer boxes 401 are symmetrically distributed at the bottom of the placement plate 404. A spring 1 is fixedly installed between the bottom of the buffer plate 402 and the inner wall of the buffer box 401, so as to be able to perform shock absorption and buffering quickly and conveniently, and thus be able to better protect the multi-line scanning laser scanner;

[0043] Furthermore, the number of moving plates 408 is two, and the moving plates 408 are symmetrically distributed on the inner wall of the heat dissipation box 301. The number of cleaning brushes 410 is two, and the cleaning brushes 410 are symmetrically distributed on one side of the two moving plates 408, so as to be able to clean the dust-proof net 302 quickly and conveniently, and thus be able to reduce the replacement frequency of the dust-proof net 302.

[0044] When in use, the operator places the multi-line scanning laser scanner inside the protective cover 1 and on the placement plate 404, and clamps and fixes the multi-line scanning laser scanner through the clamping mechanism 5. When heat dissipation is required, starting the heat dissipation mechanism 3 can quickly and conveniently dissipate heat from the multi-line scanning laser scanner. When vibration occurs during use, the movement of the placement plate 404 drives the movement of the buffer rod 403. The movement of the buffer rod 403 drives the buffer plate 402 to slide on the inner wall of the buffer box 401, and compresses the first spring and the air inside the buffer box 401. The movement of the placement plate 404 squeezes the damper 405, thereby enabling shock absorption and buffering, and further enabling better protection of the multi-line scanning laser scanner. The air inside the buffer box 401 can be transported to the telescopic airbag 407 through the air duct 406, thereby enabling the telescopic airbag 407 to expand and contract. The expansion and contraction of the telescopic airbag 407 drives the moving plate 408 to slide on the first guide rod 409. The movement of the moving plate 408 drives the movement of the cleaning brush 410. The movement of the cleaning brush 410 can clean the surface of the dust-proof net 302, thereby effectively reducing the frequency of manual replacement of the dust-proof net 302 and enabling better use.

[0045] Embodiment 3:

[0046] On the basis of Embodiment 1, the clamping mechanism 4 includes a bidirectional threaded rod 501, an adjusting plate 502, a bearing plate 503, a clamping plate 504, and a fixing bolt II 505. The outer wall of the bidirectional threaded rod 501 is threadedly connected to the inner wall of the adjusting plate 502. The top of the adjusting plate 502 is connected to the bottom of the bearing plate 503. The outer wall of the bearing plate 503 is slidably connected to the inner side of the clamping plate 504. The inner wall of the clamping plate 504 is threadedly connected to the outer wall of the fixing bolt II 505. An installation plate 506 is fixedly installed at the top of the clamping plate 504. A second guide rod 507 is fixedly installed inside the installation plate 506. A sliding plate 508 is slidably connected to the outer wall of the second guide rod 507. One end of the sliding plate 508 is fixedly installed with a pressing plate 509;

[0047] In this embodiment, the number of bearing plates 503 is two. The bearing plates 503 are symmetrically distributed on the top of the placement plate 404. An adjusting hole is provided on one side of the bearing plate 503. One end of the fixing bolt II 505 is threadedly connected to the inner wall of the adjusting hole. A second spring is fixedly installed between the top of the sliding plate 508 and the inner side of the installation plate 506, thereby enabling quick and convenient clamping and fixing of multi-line scanning laser scanners of different sizes, and further enabling better use;

[0048] Furthermore, the bottom of the protective cover 1 is interconnected with the top of the support plate 2. The protective cover 1 is made of a transparent material. One side of the protective cover 1 is interconnected with one end of the heat dissipation box 301. The inner wall of the protective cover 1 is interconnected with the bottom of the buffer box 401. The inner side of the placement plate 404 is rotatably connected to one end of the bidirectional threaded rod 501.

[0049] When in use, the operator places the multi-line scanning laser scanner inside the protective cover 1 and on the placement plate 404. By rotating the bidirectional threaded rod 501, the adjustment plate 502 is driven to move. By the movement of the adjustment plate 502, the bearing plate 503 is driven to move. By the movement of the bearing plate 503, the clamping plate 504 is driven to move, so that the multi-line scanning laser scanner can be quickly and conveniently clamped and fixed. When it is necessary to clamp and fix multi-line scanning laser scanners of different sizes, by rotating the fixing bolt two 505 to make it move inside the inner wall of the clamping plate 504, the fixing bolt two 505 can be withdrawn from one side of the bearing plate 503 by its movement, and then the limit fixation of the clamping plate 504 can be cancelled. At this time, pulling the clamping plate 504 to slide on the bearing plate 503 can quickly and conveniently adjust the position of the clamping plate 504, and then multi-line scanning laser scanners of different sizes can be clamped and fixed. And before the operator places the multi-line scanning laser scanner on the placement plate 404, by pulling the pressing plate 509 to move, the sliding plate 508 is driven to slide on the guide rod two 507, and the spring two is compressed. At this time, the multi-line scanning laser scanner is placed on the placement plate 404, and the pressing plate 509 is released. By the elastic force of the spring two, the pressing plate 509 is reset, and then the multi-line scanning laser scanner can be further clamped and fixed.
