Description

Technical Field

[0001] The present invention relates to the technical field of area laser shooting devices, and particularly to an area laser shooting device for territorial space planning. Background Art

[0002] In territorial space planning, an area laser shooting device is an important tool that uses laser technology to quickly and accurately obtain three-dimensional terrain data of large areas, providing basic information for planning work, and combining laser technology with shooting equipment to efficiently and accurately measure and record the area of a region;

[0003] During the precise measurement operation of the laser shooting device, if high-intensity light directly irradiates the surface of its laser emitter or sensor, it is easy to cause overexposure of the sensor, making the originally clear laser signal submerged by strong light, resulting in distorted measurement data, increased noise, and even direct data loss, seriously affecting the reliability of subsequent analysis and the scientific nature of engineering decisions. To avoid this situation, a corresponding light-shielding structure usually needs to be installed on the laser shooting device. However, the existing light-shielding structures are not only complex in structural design and require workers to adjust according to the position of the laser emitter during installation, with poor flexibility, but also when workers need to detect and repair the laser shooting device, they must first manually remove the light-shielding structure before they can proceed. In the case of frequent maintenance or emergency repair, the removal and reinstallation of the light-shielding structure will take a lot of time, lengthening the entire maintenance cycle and seriously affecting work efficiency. In addition, the manual removal method often requires workers to have certain professional skills and experience. If the workers' operation deviates, it is easy to damage the light-shielding structure and the laser shooting device, affecting its use.

[0004] Therefore, the present invention proposes an area laser shooting device for territorial space planning to solve the above problems. Summary of the Invention

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a laser shooting device for regional area in land space planning, which has the following beneficial effects:

[0020] 1. Through the provided light-shielding and anti-exposure mechanism, during the process of driving the pressing plate to press down and fix the laser shooting body, the side plate, the baffle plate and the light-shielding plate can be synchronously driven to slide out from above and both sides of the laser shooting body respectively. This not only reduces the extra complex mechanical structure, makes the overall structure more concise, reduces the design and manufacturing difficulty, but also when maintaining the laser shooting body, only need to release the pressing and fixing of the pressing plate, and the light-shielding structure will automatically retract with the reset of the pressing plate, without manual disassembly, saving a lot of time, shortening the maintenance cycle, improving work efficiency, and avoiding the deviation of manual operation, reducing the risk of damage to the light-shielding structure and the laser shooting body caused by improper operation, ensuring the normal use of the laser shooting body and the light-shielding mechanism, and prolonging its service life.

[0021] 2. Through the provided moving plate, limiting groove, cylinder, dial plate, connecting shaft and rotating shaft, when the laser shooting body is not in use, the baffle plates on both sides can be driven to rotate and cover the lens of the laser shooting body. This can not only effectively prevent dust, stains, water vapor and impurities from attaching, avoid lens abrasion or scratches, reduce the accumulation of dust and stains on the lens surface, reduce the frequency and difficulty of cleaning and maintenance, prolong the service life of the lens, but also when the laser shooting body is transported or stored, the baffle plates act as a physical barrier, reducing the risk of damage to the lens caused by accidental collision.

[0022] 3. By setting the bolts and threaded holes to be mutually adapted, the position of the baffle can be fixed. It can not only withstand large external force impacts and vibrations, ensuring that the baffle always maintains a fixed position under complex working conditions (such as equipment handling, transportation, or high-intensity use scenarios), avoiding loosening or displacement, but also the clearance of the thread fit is extremely small, enabling precise positioning of the baffle position, ensuring that the clearance between it and the laser shooting body or lens is uniform, and avoiding protection failure or affecting the performance of the laser shooting body caused by installation deviation.

[0023] 4. Through the provided dust removal mechanism, when the baffle rotates and covers the lens of the laser shooting body, the cleaning plate can be synchronously driven to rise to wipe the surface of the lens, cleaning the lens of the laser shooting body. It not only realizes regular cleaning of the laser shooting body, thereby reducing the wear of the lens coating by dust and pollutants and lowering the replacement cost, but also eliminates the need for staff to process the lens of the laser shooting body before using it, reducing the frequency of manual cleaning and the labor burden of the staff.

[0035] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention

[0036] A laser shooting device for regional area in territorial space planning in this embodiment, as Figures 1-7 shown, includes a bracket 1. An installation plate 2 is installed at the upper end of the bracket 1. A laser shooting body 3 is clamped on the upper end surface of the installation plate 2. It also includes a light-shielding and anti-exposure mechanism and a dust removal mechanism. The light-shielding and anti-exposure mechanism includes a pressing plate 404, a light-shielding plate 405, symmetrically arranged side plates 408, a baffle 409 and a poking rod 410. The light-shielding plate 405 is slidably connected through the pressing plate 404. The side plates 408 are all slidably connected to the upper end surface of the installation plate 2. The light-shielding and anti-exposure mechanism is used to synchronously drive the light-shielding plate 405, the side plates 408 and the baffle 409 to shield the laser shooting body 3 during the process of fixing the laser shooting body 3

[0037] In this embodiment, as Figure 4 and Figure 6 shown, rotating shafts 421 are rotatably connected through the side plates 408 close to the baffle 409. The baffles 409 are fixedly connected to the rotating shafts 421. The poking rods 410 are fixedly connected to the lower end surfaces of the baffles 409. Connecting shafts 413 are slidably penetrated through the upper ends of the rotating shafts 421. Vertical grooves 422 are symmetrically opened on the outer surfaces of the connecting shafts 413. Vertical plates 423 are symmetrically and fixedly connected inside the rotating shafts 421. The vertical plates 423 are all slidably connected in the vertical grooves 422. The connecting shafts 413 are all rotatably connected through the light-shielding plate 405. When the light-shielding plate 405 descends, it can push the connecting shaft 413 into the inside of the rotating shaft 421. When the connecting shaft 413 rotates, the rotating shaft 421 can be driven to rotate synchronously through the vertical groove 422 and the vertical plate 423

[0038] In this embodiment, Figure 2 and Figure 3 As shown, the light-shielding and exposure-prevention mechanism also includes a gantry 401, which is fixedly connected to the upper end surface of the mounting plate 2, and a threaded rod 402 is threadedly connected at the center of the gantry 401, and a hand wheel 403 is fixedly connected to the upper end of the threaded rod 402, and the lower end of the threaded rod 402 is rotatably connected to the upper end surface of the pressing plate 404, and lifting blocks 412 are fixedly connected on both sides of the pressing plate 404, and the gantry 401 is symmetrically provided with through grooves 411, and the lifting blocks 412 are slidably connected in the through grooves 411. When the hand wheel 403 is rotated to drive the threaded rod 402 to rotate on the gantry 401, the threaded rod 402 and the gantry 401 are threadedly connected, so that the threaded rod 402 can be driven to rise and fall on the gantry 401, and the pressing plate 404 to which the lower end of the threaded rod 402 is rotatably connected is pushed up and down, and the lifting blocks 412 connected on both sides of the pressing plate 404 are driven to slide in the through grooves 411.

[0039] In this embodiment, Figure 2 and Figure 3 As shown, the lifting block 412 is rotatably connected to the push plate 406 on the side away from the pressing plate 404, and the push plate 406 is rotatably connected to the connecting column 407 on the side away from the lifting block 412. The connecting column 407 is fixedly connected to the side wall of the side plate 408. When the lifting block 412 moves up and down, the push plate 406 can push the side plate 408 to slide synchronously horizontally on the upper end surface of the mounting plate 2.

[0040] In this embodiment, Figure 4 As shown, the upper end surface of the shading plate 405 is slidably connected to a movable plate 414, and a limiting groove 417 is symmetrically provided on the upper end surface of the movable plate 414. A cylinder 416 is slidably connected in the limiting groove 417, and a dial plate 415 is fixedly connected to the upper end of the cylinder 416. The dial plate 415 is fixedly connected to the upper end of the connecting shaft 413. When the movable plate 414 slides on the upper end surface of the shading plate 405, the limiting groove 417 can be used to drive the cylinder 416 to drive one end of the dial plate 415 to move synchronously, so that the dial plate 415 drives the connecting shaft 413 to rotate on the shading plate 405.

[0041] In this embodiment, Figure 5As shown, a bolt 419 is threadedly connected through the center of the moving plate 414. The upper end of the bolt 419 is fixedly connected to a knob 420. Two threaded holes 418 are provided on the upper end surface of the light-shielding plate 405. The threaded holes 418 are all adapted to the bolt 419. When the knob 420 is rotated to drive the bolt 419 to rotate and slide into the threaded hole 418, the position of the moving plate 414 can be limited, avoiding the situation that the moving plate 414 moves automatically due to other external factors. And the distance of the movement of the moving plate 414 can be controlled through the provided threaded holes 418.

[0042] In the prior art, the light-shielding structure is not only complex in structural design and requires workers to adjust according to the position of the laser emitter during installation, with poor flexibility, but also when workers need to detect and repair the laser shooting device, they must first manually remove the light-shielding structure before they can proceed. In the case of frequent subsequent maintenance or emergency repair, the removal and reinstallation of the light-shielding structure will take a lot of time, resulting in a lengthened overall maintenance cycle and seriously affecting work efficiency. In addition, the manual removal method often requires workers to have certain professional skills and experience. If the workers' operation deviates, it is easy to damage the light-shielding structure and the laser shooting device, affecting the use. Compared with the prior art, during the process of driving the pressing plate 404 to press down and fix the laser shooting body 3, the side plate 408, the baffle 409 and the light-shielding plate 405 can be synchronously driven to slide out from above and on both sides of the laser shooting body 3 respectively, which not only reduces the extra complex mechanical structure, makes the overall structure more concise, and reduces the design and manufacturing difficulty, but also when maintaining the laser shooting body 3, only the pressing fixation of the pressing plate 404 needs to be released, so that the light-shielding structure automatically retracts with the reset of the pressing plate 404 without manual removal, saving a lot of time, shortening the maintenance cycle, improving work efficiency, and avoiding the deviation of manual operation, reducing the risk of damage to the light-shielding structure and the laser shooting body 3 caused by improper operation, ensuring the normal use of the laser shooting body 3 and the light-shielding mechanism, and extending its service life.

[0043] On other levels, this embodiment also provides a dust removal mechanism for protecting the lens of the laser shooting body 3 and wiping the dust on the lens at the same time, as Figure 2 and Figure 7 shown, the dust removal mechanism includes a fixing plate 501, the fixing plate 501 is fixedly connected to the side wall of the mounting plate 2, and sliding columns 507 are symmetrically and slidably connected through the fixing plate 501. A lifting plate 502 is fixedly connected between the upper ends of the two sliding columns 507. A cleaning plate 508 is fixedly connected to the side of the lifting plate 502 close to the laser shooting body 3.

[0044] In this embodiment, as Figure 7As shown in the figure, a jacking plate 506 is rotatably connected to one side of the lifting plate 502 away from the cleaning plate 508. A sliding plate 503 is rotatably connected to one side of the jacking plate 506 away from the lifting plate 502. The sliding plate 503 is slidably connected to the upper end surface of the fixing plate 501. When the sliding plate 503 slides on the upper end surface of the fixing plate 501, through the arranged jacking plate 506, the lifting plate 502 can be pushed to rise and fall synchronously.

[0045] In this embodiment, as Figure 7 shown, symmetric grooves 504 and notches 505 are formed on the upper end surface of the sliding plate 503. The grooves 504 are all adapted to the dial rods 410. When the dial rods 410 move, they will move from the notches 505 to the grooves 504. Along with the continuous movement of the dial rods 410, the dial rods 410 will slide in the grooves 504, and the sliding plate 503 will be toggled to slide on the upper end surface of the fixing plate 501 through the grooves 504.

[0046] Compared with the prior art, when the baffle 409 rotates to cover the lens of the laser shooting body 3, the cleaning plate 508 can be synchronously driven to rise to wipe the surface of the lens, cleaning the lens of the laser shooting body 3. This not only realizes the regular cleaning of the laser shooting body 3, thereby reducing the wear of the lens coating by dust and pollutants and lowering the replacement cost, but also eliminates the need for the staff to process the lens of the laser shooting body 3 before using the laser shooting body 3, reducing the manual cleaning frequency and the labor burden of the staff.

[0047] The working process and principle involved in the overall content of the above embodiment are as follows:

[0048] It should be noted that the cleaning plate 508 can be made of ultra-fine fiber cloth or flexible silicone squeegee to avoid scratches or electrostatic adsorption generated in the traditional wiping method.

[0049] After the staff clips the laser shooting body 3 above the mounting plate 2, the staff can rotate the handwheel 403 to drive the threaded rod 402 to rotate. Since the threaded rod 402 is threadedly connected to the gantry 401, the threaded rod 402 can rotate and slide downward on the gantry 401. Since the threaded rod 402 is rotatably connected to the upper end surface of the pressing plate 404, both sides of the pressing plate 404 are connected with lifting blocks 412, and the lifting blocks 412 are slidably connected to the through grooves 411. Therefore, during the rotation and descent of the threaded rod 402, through the sliding connection between the lifting blocks 412 and the through grooves 411, the pressing plate 404 can be pushed to descend synchronously and press on the laser shooting body 3 below, fixing the laser shooting body 3 firmly above the mounting plate 2 and improving the stability of the laser shooting body 3 during the measurement process;

[0050] As the pressing plate 404 descends, the pressing plate 404 will drive the slidably connected light shielding plate 405 on one side to descend synchronously, and the connecting shaft 413 symmetrically connected to the light shielding plate 405 will synchronously slide into the rotating shaft 421. As the pressing plate 404 drives the lifting block 412 to slide downward in the through groove 411, the upper end of the push plate 406 rotatably connected to the side wall of the lifting block 412 synchronously slides vertically downward, so that the push plate 406 moves from an inclined state to a horizontal state. When the state of the push plate 406 changes, the push plate 406 will push the side plate 408 to synchronously slide out on the upper end surface of the mounting plate 2 through the connecting column 407 rotatably connected to one end away from the lifting block 412. When the side plate 408 slides out, the side plate 408 can push the baffle 409 synchronously through the connected rotating shaft 421. The rotating shaft 421 will move the connecting shaft 413, driving the shading plate 405 to slide out from the inside of the pressing plate 404 synchronously, so that the side plate 408, the baffle plate 409 and the shading plate 405 slide out from the top and both sides of the laser shooting body 3 respectively, which not only reduces the additional complex mechanical structure, makes the overall structure more concise, and reduces the difficulty of design and manufacturing, but also when maintaining the laser shooting body 3, it is only necessary to release the downward pressing fixation of the pressing plate 404, so that the shading structure is automatically retracted with the reset of the pressing plate 404, without manual removal, saving a lot of time, shortening the maintenance cycle, improving work efficiency, avoiding deviations in manual operation, reducing the risk of damage to the shading structure and the laser shooting body 3 due to improper operation, ensuring the normal use of the laser shooting body 3 and the shading mechanism, and extending their service life;

[0051] After the laser shooting body 3 has completed the area measurement of the area, the staff can turn the knob 420 to drive the bolt 419 to rotate. Through the threaded connection between the bolt 419 and the movable plate 414, the bolt 419 can be rotated and raised from the movable plate 414, and at the same time slide out of one of the threaded holes 418 opened on the shading plate 405. After the bolt 419 and one of the threaded holes 418 are completely separated, the staff can push the knob 420 to slide the movable plate 414 on the upper end surface of the shading plate 405 toward the pressing plate 404 through the bolt 419. Since the movable plate 414 has limiting grooves 417 on both sides, the limiting grooves 417 are slidably connected with cylinders 416, and the cylinders 416 are fixedly connected to the lower end surface of the dial plate 415, and the dial plate 415 is fixedly connected to the upper end of the connecting shaft 413, during the horizontal movement of the movable plate 414, the limiting grooves 417 will drive the cylinder 416 to slide. One end of the dial plate 415 moves synchronously, so that the dial plate 415 drives the connecting shaft 413 to rotate on the shading plate 405, and the outer surface of the connecting shaft 413 is provided with a vertical groove 422, and the inner wall of the rotating shaft 421 is connected with a vertical plate 423, and the vertical plate 423 is slidably connected in the vertical groove 422. Therefore, during the rotation of the connecting shaft 413, the rotating shaft 421 will be driven to rotate synchronously on the side plate 408 through the vertical groove 422 and the vertical plate 423, driving the baffles 409 connected to the outer surfaces of the rotating shafts 421 on both sides to rotate close to each other and cover the lens of the laser shooting body 3, which can not only effectively prevent dust, stains, water vapor and impurities from adhering, avoid lens wear or scratches, reduce the accumulation of dust and stains on the lens surface, reduce the frequency and difficulty of cleaning and maintenance, and extend the service life of the lens, but also when the laser shooting body 3 is transported or stored, the baffle 409 acts as a physical barrier to reduce the risk of damage to the lens due to accidental collision;

[0052] After the baffle 409 rotates and moves to the specified position, the staff can rotate the knob 420 in the opposite direction again to drive the bolt 419 to rotate in the opposite direction, so that the bolt 419 rotates and slides downward on the movable plate 414, and slides into another threaded hole 418 opened on the upper end surface of the shading plate 405 again, so as to limit the position of the movable plate 414, so that the position of the baffle 409 can be fixed by the limiting groove 417, the cylinder 416, the dial plate 415, the connecting shaft 413 and the rotating shaft 421, which can not only withstand large external impact and vibration, but also ensure that the baffle 409 always maintains a fixed position under complex working conditions (such as equipment handling, transportation or high-intensity use scenarios) to avoid loosening or displacement, and the gap of the thread matching is extremely small, which can realize the precise positioning of the position of the baffle 409, ensure that the gap between it and the laser shooting body 3 or the lens is uniform, and avoid protection failure or affecting the performance of the laser shooting body 3 due to installation deviation;

[0053] During the process of the baffle 409 rotating to cover the lens of the laser shooting body 3, the lever 410 connected to the lower end face of the baffle 409 will move synchronously with the rotation center of the rotating shaft 421. At this time, the lever 410 will rotate and move into the groove 504 through the notch 505 opened on the slide plate 503. As the lever 410 continues to move, the lever 410 will slide deeper along the edge of the groove 504, and at the same time, the lever 410 will push the slide plate 503 to slide towards the lifting plate 502 on the upper end face of the fixed plate 501 through the groove 504. As the slide plate 503 moves, since the lifting plate 506 is rotatably connected between the slide plate 503 and the lifting plate 502, and the lower end face of the lifting plate 502 is symmetrically and fixedly connected with the sliding columns 507, and the sliding columns 507 penetrate through and are slidably connected to the fixed plate 501, therefore, during the process of the slide plate 503 moving closer to the lifting plate 502, through the arranged lifting plate 506 and the sliding columns 507, the lifting plate 502 can be pushed to slide vertically upward, driving the cleaning plate 508 connected to the side of the lifting plate 502 close to the laser shooting body 3 to rise synchronously, so that the cleaning plate 508 wipes the lens of the laser shooting body 3 and cleans the lens of the laser shooting body 3. This not only realizes the regular cleaning of the laser shooting body 3, thereby reducing the wear of the lens coating caused by dust and pollutants and reducing the replacement cost, but also eliminates the need for the staff to process the lens of the laser shooting body 3 before using the laser shooting body 3, reduces the frequency of manual cleaning, and reduces the labor burden of the staff;

[0054] When the baffle 409 rotates away from the lens of the laser shooting body 3, the lever 410 connected to the lower end of the baffle 409 will synchronously push the slide plate 503 to move horizontally away from the lifting plate 502 on the upper end face of the fixed plate 501 through the groove 504, driving the lifting plate 506 to pull the lifting plate 502 to descend vertically, so that the cleaning plate 508 connected to the side wall of the lifting plate 502 cleans the lens of the laser shooting body 3 again, and avoids the situation that the lifting plate 502, the cleaning plate 508 and the lifting plate 506 block the laser shooting body 3. After the lever 410 slides the slide plate 503 on the fixed plate 501 to a specified position through the groove 504, the lever 410 will rotate out from the notch 505 opened on the fixed plate 501 and separate from the groove 504.
