Description

Technical Field

[0001] This invention relates to the field of ancient building monitoring technology, specifically a laser-type ancient building monitoring and scanning device. Background Technology

[0002] Protecting and restoring ancient buildings not only reflects respect for history but also the responsibility for the inheritance of cultural heritage. In this process, detailed architectural surveying is crucial. However, traditional manual surveying often requires direct contact with the building itself, which not only increases the risk of damage to the ancient building but also makes it difficult to guarantee the efficiency of the survey and the rigor of the data.

[0003] To overcome the aforementioned shortcomings, prior art 1 (Chinese patent CN115420198B, published on April 5, 2024) discloses a BIM-based 3D laser scanning device for ancient buildings and its usage method. This method involves simultaneously performing multi-directional fixed-point scanning of an ancient building using multiple 3D laser scanners to obtain initial point cloud images. A second fixed-point scan is then performed after adjusting the scanning coordinates of each 3D laser scanner using a positioning device. This avoids or reduces the number of movements required. The method has fewer movements, requires fewer laser point cloud images to be stitched together, and has a faster image integration speed. Using a fixed-point scanning method, compared to mobile scanning, it avoids the situation where some details of the target ancient building cannot be scanned due to excessively fast movement. Prior art 2 (CN215639308U, published on January 2022) (Chinese Patent No. 25) A 3D laser scanner for monitoring building deformation includes a base. Universal wheels and traveling wheels are respectively installed on the left and right sides of the lower surface of the base. A telescopic support rod is fixedly connected to the upper surface of the base. A platform is hinged to the upper end of the inner rod of the telescopic support rod. A drive motor is installed in a mounting groove on the upper surface of the platform. The output shaft of the drive motor is fixedly connected to a rotating platform via a rotating shaft. The scanner body is connected to the upper surface of a mounting plate hinged to the front side of the rotating platform. A screw is connected to the middle of the rear inner wall of the rotating platform. A support rod is hinged to the upper side of a threaded sliding sleeve on the screw. The other end of the support rod is hinged to the middle of the lower surface of the mounting plate. A storage box is placed in a groove on the upper surface of the base. This 3D laser scanner is easy to move, can monitor multiple points, and allows for easy adjustment of the height, horizontal angle, and vertical angle of the scanner body. It can comprehensively monitor building deformation, and is easy to disassemble, assemble, and store the scanner body, making it highly practical.

[0004] While existing 3D laser scanners can scan ancient buildings, their complex structures, such as bases, telescopic supports, and rotating platforms, make the overall size of the equipment large. This increases the difficulty of operation and spatial constraints when working in confined spaces or on intricate architectural details. Furthermore, when the external ambient temperature is too high or too low during operation, existing laser monitoring equipment struggles to effectively regulate the temperature, leading to overheating or underheating, which affects the reliability of data processing and reduces the overall lifespan of the equipment.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on existing laser-based ancient building monitoring and scanning equipment. Therefore, we proposed that laser-based ancient building monitoring and scanning equipment can effectively solve the above problems. Summary of the Invention

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: In this example, a low-boiling-point liquid is placed into the temperature-regulating cavity 11. When the device temperature is too high, the liquid evaporates and absorbs heat, and the vapor is discharged through the channel 12 to dissipate heat. This utilizes the physical properties of liquid evaporation to efficiently dissipate heat, resulting in stable and environmentally friendly heat dissipation. When the temperature is too low, the heating element 14 activates to heat the liquid, maintaining a constant temperature for the processor 2 and ensuring the stability of data processing. Figures 1-6The technical solution shown includes a laser detection component 1, a processor 2 mounted on the bottom of the laser detection component 1, a receiver 3 adapted to the laser detection component 1 mounted on the processor 2, an adjustment base 4 below the processor 2, the adjustment base 4 including a quick-adjustment robotic arm and a moving drive wheel, a first heat dissipation hole 5 on the side of the processor 2, a shape memory alloy sheet 6 installed inside the processor 2, the shape memory alloy sheet 6 located inside the first heat dissipation hole 5, a dust cover 7 connected to the outside of the processor 2 by bolts, the dust cover 7 located outside the first heat dissipation hole 5, a temperature regulating component on the inner wall of the processor 2, the temperature regulating component including a temperature regulating cavity 11 opened in the inner wall of the processor 2, a through groove 12 on the top of the processor 2, the through groove 12 communicating with the temperature regulating cavity 11, and temperature regulation. A heating element 14 is installed inside cavity 11. A second protective cover 13 is threadedly connected inside through groove 12. A heat dissipation assembly is installed at the bottom of processor 2. The heat dissipation assembly includes a second heat dissipation hole 8 opened at the bottom of processor 2. A dustproof sheet 9 is installed inside the second heat dissipation hole 8. A first protective cover 10 is snapped onto the bottom of the second heat dissipation hole 8. The device is moved by the drive wheel of the adjusting seat 4, which facilitates the flexible adjustment of the monitoring position of the device in the complex site of ancient buildings, improves the site adaptability of the device, and the mechanical arm of the adjusting seat 4 can realize the rapid adjustment of the position of laser detection element 1, which can quickly align with different monitoring points, reduce equipment debugging time, improve monitoring efficiency, and facilitate the laser detection element 1 to emit laser to scan and monitor ancient buildings and obtain structural data. Receiver 3 and laser The optical detection element 1 is adapted to receive reflected laser signals and transmit them to the processor 2, ensuring the accuracy of data transmission and providing a reliable basis for subsequent data processing. The processor 2 receives signals from the laser detection element 1 and processes the data, realizing real-time analysis and integration of ancient building structure data, providing data support for monitoring results. Its small overall size facilitates detection in different spaces, reducing operational difficulty and space constraints. The internal components of the processor 2 generate heat during operation. When the temperature rises, the shape memory alloy sheet 6 deforms, opening the first heat dissipation hole 5. When the temperature drops, the shape memory alloy sheet 6 resets and closes, achieving passive heat dissipation regulation without additional power, saving energy and automatically adapting to temperature changes to ensure the processor 2 operates at a suitable temperature. The dust cover 7 is bolted to the outside of the first heat dissipation hole 5 to prevent dust from entering the processor 2 and to avoid dust adhering to internal components, affecting their performance and extending the equipment's lifespan. A low-boiling-point liquid is filled into the temperature control chamber 11. When the device temperature is too high, the liquid evaporates and absorbs heat; the vapor is discharged through the channel 12 for heat dissipation. This utilizes the physical properties of liquid evaporation for efficient and stable heat dissipation, which is also environmentally friendly. When the temperature is too low, the heating element 14 activates to heat the liquid, maintaining a constant temperature for the processor 2 and ensuring its normal operation even in low-temperature environments, thus guaranteeing data processing stability. At this time, the channel 12 can be closed by the second protective cover 13 to reduce heat loss and enhance the equipment's insulation performance. The second heat dissipation hole 8 at the bottom of the processor 2 facilitates heat dissipation.Users can open multiple secondary heat dissipation holes 8 at high temperatures to enhance heat dissipation and adapt to different temperature environments. The secondary heat dissipation holes 8 are located at the bottom of the processor 2, utilizing the principle of hot air rising to improve heat dissipation efficiency. Furthermore, the dustproof sheet 9 inside the secondary heat dissipation holes 8 can block dust, further enhancing the dustproof effect. The first protective cover 10, which snaps into the secondary heat dissipation holes 8, is conveniently attached at low temperatures, thus maintaining the temperature of the processor 2. Overall, the operation is simple, quickly achieving the heat preservation function and improving the lifespan of the device.

[0025] Example 2: In this example, the peristaltic pump 19 is linked to the rotating shaft 17 via a rotating shaft, and its delivery pipe 20 connects both sides of the temperature-regulating chamber 11, realizing the circulation of liquid within the temperature-regulating chamber 11 and improving heat exchange efficiency. Specifically, as follows... Figure 5 and Figure 7 As shown, the following is disclosed: a drive box 15 is provided on the side of the processor 2, and a drive assembly is provided inside the drive box 15. The drive assembly includes a dual-axis motor 16 installed inside the drive box 15. The first output end of the dual-axis motor 16 is connected to a rotating shaft 17, which runs through the processor 2. A fan blade 18 is installed on the outside of the rotating shaft 17. A peristaltic pump 19 is provided inside the drive box 15. The rotating shaft inside the peristaltic pump 19 is connected to the rotating shaft 17. The delivery pipe 20 inside the peristaltic pump 19 is connected to the temperature regulating chamber 11. The two ends of the delivery pipe 20 are located on both sides of the temperature regulating chamber 11. The dual-axis motor 16 inside the drive box 15 is turned on intermittently as needed. The first output end of the dual-axis motor 16 is connected to the rotating shaft 17. The rotating shaft 17 drives the fan blades 18 to rotate inside the processor 2, accelerating airflow and enhancing heat dissipation efficiency. The peristaltic pump 19 is linked to the rotating shaft 17 via a rotating shaft, and its delivery pipe 20 connects both sides of the temperature regulating chamber 11, realizing the circulation of liquid within the temperature regulating chamber 11 and improving heat exchange efficiency. No additional power is needed to drive the peristaltic pump 19, saving energy. At the same time, it increases the heat exchange speed of the temperature regulating chamber 11. The protective cover 27 installed on the processor 2 reduces the temperature rise caused by direct sunlight in high-temperature environments, reduces the impact of the external environment on the temperature of the processor 2, and reduces heat dissipation pressure. In low-temperature environments, it reduces the direct blowing of cold air onto the equipment, providing a good working environment for the equipment and ensuring the stability of the equipment under different climatic conditions.

[0026] Example 3: In this example, since the bottom of the first moving rod 26 is connected to the cleaning brush 28, the cleaning brush 28 reciprocates above the dust cover 7 to remove dust from the surface of the dust cover 7, preventing blockage of the first heat dissipation hole 5. Automatic cleaning is achieved using the power of the dual-axis motor 16, eliminating the need for manual operation and maintaining heat dissipation. Specifically, as shown... Figure 4 , Figure 5 and Figures 7-11As shown, the following is disclosed: the second output end of the dual-axis motor 16 is connected to a piston 23 via a crankshaft 21; a conveying cylinder 22 is provided inside the drive box 15; the piston 23 is connected through the conveying cylinder 22; a protective cover 27 is installed on the processor 2; a first sleeve 25 is provided on the side end of the protective cover 27; the conveying cylinder 22 is connected through the first pipe 24 to the inside of the first sleeve 25; a first moving rod 26 is movably connected inside the first sleeve 25; a cleaning brush 28 is connected to the bottom of the first moving rod 26; the cleaning brush 28 is located directly above the dust cover 7; a spring 29 is sleeved on the outside of the first moving rod 26 and the first sleeve 25; a second sleeve 31 is provided on the side end of the protective cover 27; the second sleeve 31 is located directly above the first sleeve 25, and the first... A second moving rod 30 is mounted on the top of a moving rod 26. The second moving rod 30 passes through the inside of a second sleeve 31. The input end of the second sleeve 31 is connected to a suction component 33 via a second pipe 32. The suction component 33 is located at the lower end of the protective cover 27 and is symmetrically arranged on both sides of the laser detection component 1. A processing cylinder 35 for storing liquid is symmetrically arranged below the protective cover 27. The output end of the second sleeve 31 is connected to the bottom of the processing cylinder 35 via a third pipe 34. A through hole 36 is opened on the inner side of the processing cylinder 35, located on both sides of the laser detection component 1. When the dual-axis motor 16 is in use, its second output end drives the piston 23 to reciprocate within the conveying cylinder 22 via a crankshaft 21. The conveying cylinder 22 is connected to the first pipe 24. The first sleeve 25 is connected to the first sleeve 25, so gas is input into the first sleeve 25 through the first pipe 24, and pushes the first moving rod 26 to move up and down along the first sleeve 25. The spring 29 on the outside of the first sleeve 25 is stretched by the first moving rod 26. Since the bottom of the first moving rod 26 is connected to the cleaning brush 28, the cleaning brush 28 moves back and forth above the dust cover 7 to remove dust from the surface of the dust cover 7 and avoid clogging the first heat dissipation hole 5. Automatic cleaning is achieved by the power of the dual-axis motor 16 without manual operation, maintaining the heat dissipation effect. The second moving rod 30 at the top of the first moving rod 26 moves inside the second sleeve 31, so that the second sleeve 31 is connected to the suction component 33 through the second pipe 32. The suction component 33 is located on both sides of the laser detection component 1. The side can suck in dust around the laser detection component 1, promptly removing dust around the laser detection component 1 to ensure detection accuracy. When the dual-axis motor 16 is turned off, the first moving rod 26 is reset by the rebound of the spring 29 on the outside of the first sleeve 25 through the first moving rod 26. Reset can be achieved without additional power, making the structure simple and energy-saving. The second moving rod 30 at the upper end of the first moving rod 26 can move easily inside the second sleeve 31, so that the gas inside the second sleeve 31 is sent into the processing cylinder 35 through the third pipe 34. The processing cylinder 35 is filled with liquid, so the gas is processed by the liquid after being delivered to the processing cylinder 35. The cleaned gas is discharged through the through hole 36, reducing dust accumulation on the surface of the laser detection component 1 and ensuring detection accuracy.
