Description

Technical Field

[0001] This invention belongs to the field of detection equipment technology, and in particular relates to a three-dimensional scanning monitoring device for engineering foundations. Background Technology

[0002] 3D laser scanning technology is a non-contact, active, and rapid method for acquiring dense 3D point clouds of object surfaces, providing high spatiotemporal resolution for 3D Earth observation. A 3D laser scanning system mainly consists of a computer, power supply, 3D laser scanner, digital camera, and controller. It actively acquires 3D coordinates and certain attributes of an object's surface, such as reflectance intensity, in an irregularly spatially distributed 3D point cloud. It boasts high accuracy, fast measurement speed, and wide application range. It can also acquire texture and color information of the target object and perform various post-processing analyses. 3D laser scanning technology has been widely applied in topographic foundation surveying and deformation monitoring of landslides and buildings. Currently, foundation measurement and monitoring are key aspects of construction projects. 3D laser scanners provide a high-precision and efficient means for monitoring engineering foundations, helping to promptly detect and address foundation deformation problems, ensuring the safe operation of projects. However, 3D laser scanners are often installed outdoors, resulting in poor protection and affecting their monitoring accuracy and efficiency.

[0003] To this end, Chinese invention patent CN112082497B discloses a 3D laser scanner, including a frame, a rotating base, and a scanner body. The rotating base is rotatable, and the scanner body is fixedly connected to the rotating base. It also includes a rain cover, which includes a fixed cover and a movable cover. The fixed cover is fixedly connected to the rotating base, and the movable cover is rotatably connected to the rotating base. The fixed cover and the movable cover are sleeved together. The rain cover can completely cover the scanner body and protect the scanner body when it rains or is windy.

[0004] However, when the above-mentioned device is used outdoors, a lot of dust easily accumulates on the fixed cover and the movable cover. When the movable cover rotates on the fixed cover, it is easy to shake off the dust and enter the probe of the scanner body, causing contamination and affecting the accuracy of the 3D laser scanner detection, which in turn affects the efficiency and quality of monitoring. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides a three-dimensional scanning monitoring device for engineering foundations. It features convenient adjustment of the rotation angle of the three-dimensional laser scanner, expanding the detection range and offering flexible use. The rain cover is easy to store and extend, providing excellent dust protection and preventing dust from contaminating the 3D laser scanner probe. It also provides comprehensive rain, wind, and dust protection, improving detection accuracy, extending instrument lifespan, and increasing detection efficiency. This invention solves the problem in existing technologies where, during outdoor use, fixed and movable covers easily accumulate large amounts of dust. When the movable cover rotates on the fixed cover, the dust on it is easily shaken off and enters the scanner probe, causing contamination and affecting the accuracy of the 3D laser scanner, thus impacting monitoring efficiency and quality.

[0006] This invention is implemented as follows: a three-dimensional scanning monitoring device for engineering foundations includes a frame, a support rod fixedly connected to the side wall of the frame, a support block fixedly connected to the side wall of the support rod, a fixed ring seat fixedly connected to the end of the support block, a support platform connected to the inside of the fixed ring seat via a bearing, a three-dimensional laser scanner fixedly mounted on the top of the support platform, and the bottom of the support platform mounted on the top of the frame via a rotating adjustment component. A protective component is mounted on the top of the support rod, the protective component including a top cover and an inner cover, a rain cover inserted and positioned between the top cover and the inner cover, a lifting plate fixedly connected to the bottom of the rain cover, and a conical turntable. The top of the conical turntable can drive the support platform to rotate, and the side wall of the conical turntable can drive the lifting plate to move up and down.

[0007] This design, through the coordination of the rotating adjustment mechanism and the support platform, facilitates the adjustment of the rotation angle of the 3D laser scanner, expanding the detection range and providing greater flexibility. This improves monitoring efficiency. Furthermore, the combination of the rotating adjustment mechanism and the protective components allows for easy retraction and extension of the rain cover. In normal weather, the rain cover is retracted between the top and inner covers for storage, providing excellent dust protection and preventing dust contamination. In rainy, snowy, or windy conditions, the lifting plate extends the rain cover to protect the 3D laser scanner, preventing dust from contaminating the scanner's probe. This comprehensive rain, wind, and dust protection helps ensure the detection accuracy of the 3D laser scanner, extends its service life, and further improves monitoring efficiency.

[0008] In a preferred embodiment of the present invention, the bottom of the conical turntable is connected to the top of the frame via a bearing. A mounting groove is provided on the top front of the frame, and a motor is fixedly connected to the bottom of the mounting groove. The output end of the motor passes through the frame and is fixedly connected to the bottom of the conical turntable. A toothed section is fixedly connected to the side wall of the conical turntable.

[0009] This design effectively improves the stability of the conical turntable mounting structure, making it easier for the motor to drive the conical turntable to rotate.

[0010] In a preferred embodiment of the present invention, a main rotating rod and an auxiliary rotating rod are respectively connected to both sides of the mounting groove via bearings. A bevel gear is sleeved and fixed on the main rotating rod, and the toothed section is meshed with the bevel gear. A toothed ring is sleeved and fixed on the ends of both the main rotating rod and the auxiliary rotating rod.

[0011] With this configuration, the conical turntable can drive the main rotating rod to rotate through the toothed section and the conical gear. The toothed ring can easily cooperate with the toothed plate on the lifting plate. That is, the main rotating rod drives the toothed ring to rotate, the toothed ring drives the toothed plate to move up and down, and then the toothed plate drives the lifting plate to move up and down, thereby realizing the retraction and extension of the protective cover, making it flexible to use.

[0012] In a preferred embodiment of the present invention, a fixing block is fixedly connected to the top of the support rod. The fixing block passes through the top cover, the rain cover, and the inner cover sequentially from top to bottom. The top cover and the inner cover are both fixed to the fixing block by bolts. A through hole is provided in the middle of the rain cover, and the through hole is inserted into the fixing block. A storage groove is provided between the top cover and the inner cover, and the rain cover is placed in the storage groove. The rain cover is made of transparent elastic silicone material with a pleated structure.

[0013] This design facilitates the installation and storage of the rain cover, preventing excessive dust accumulation during everyday use. This, in turn, helps avoid dust contamination of the 3D laser scanner's probe when the rain cover is extended, thereby improving the scanner's detection accuracy during operation.

[0014] In a preferred embodiment of the present invention, toothed plates are fixedly connected to both ends of the bottom of the lifting plate, and the toothed plates are meshed with one side of the toothed ring. A limiting rod is fixedly connected to the toothed plate, and the limiting rod is attached to the other side of the toothed ring. The inner side of the limiting rod slides up and down along the toothed ring.

[0015] With this design, the rotation of the gear ring drives the gear plate to move up and down, which in turn drives the lifting plate and the rain cover to move up and down, thus enabling the rain cover to retract and extend. It is convenient and flexible to use. The limit rod helps to ensure the stability of the connection structure between the gear plate and the gear ring, which in turn helps to ensure the stability of the rain cover when it moves up and down.

[0016] In a preferred embodiment of the present invention, an annular groove is provided at the top of the conical turntable, and a first push block is fixedly connected to the annular groove. The bottom of the support platform and the conical turntable are separated by a gap. A guide block and a second push block are fixedly connected to the upper and lower side walls of the support platform, respectively, and the first push block slides against the second push block.

[0017] With this setup, when the rain cover needs to be stored, the motor drives the conical turntable to rotate. The conical gear enters the toothed section of the conical turntable, and the toothed plate moves upward along the toothed ring, gradually pushing the lifting plate upward until it compresses and pushes the rain cover into the storage slot. At the same time, the conical turntable drives the first push block to rotate synchronously. The first push block gradually approaches the second push block. When the rain cover enters the storage slot, the first push block rotates to the position where it is in contact with the second push block, and the toothed section disengages from the hammer gear. Finally, the motor is turned off to stop the conical turntable from rotating, thus realizing the storage of the rain cover. When the angle of the 3D laser scanner needs to be adjusted, the motor drives the conical turntable to continue rotating. At this time, the conical turntable drives the first push block to push the second push block, which in turn drives the support platform to rotate, thereby realizing the adjustment of the angle of the 3D laser scanner.

[0018] In a preferred embodiment of the present invention, a guide groove is provided on the fixed ring seat, a stop block is fixedly connected to the guide groove, the bottom of the guide block slides along the guide groove, and the guide block and the stop block are fixedly connected by a spring, the spring being placed in the guide groove.

[0019] With this setup, when the angle of the 3D laser scanner needs to be adjusted, the conical turntable pushes the support platform through the cooperation of the first and second push blocks. At this time, the rotating support platform drives the guide block to slide along the guide groove and acts on the spring to make it elastically stressed, ensuring the stability of the support platform when it moves. When the 3D laser scanner needs to be rotated in the opposite direction, the motor drives the conical turntable to rotate in reverse. At this time, under the elastic force, the second push block will stick to the first push block and follow the first push block to move in the opposite direction, making the adjustment flexible.

[0020] As a preferred embodiment of the present invention, a clearance groove is provided between the rain cover and the lifting plate, and the clearance groove is engaged with the support block.

[0021] This design allows the rain cover to be stably positioned around the 3D laser scanner for protection, avoiding the obstruction of the rain cover by the support blocks.

[0022] As a preferred embodiment of the present invention, a controller is fixedly installed on the mounting slot, and a wind, light and rain sensor is fixedly installed on the top of the top cover. The wind, light and rain sensor and the motor are all electrically connected to the controller.

[0023] With this setup, when the wind, light, and rain sensor detects rain or wind signals, it sends a signal to the controller. The controller then starts the motor, which in turn rotates the conical turntable. This allows the rain cover to extend downwards, providing comprehensive protection for the 3D laser scanner. When normal weather returns, the activation device retracts the rain cover between the top cover and the inner cover for storage, making it flexible to use.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: The rotation angle of the 3D laser scanner can be easily adjusted by the cooperation of the rotating adjustment component and the support platform, expanding the detection range and providing greater flexibility, which is beneficial to improving monitoring efficiency. Furthermore, the cooperation of the rotating adjustment component and the protective assembly facilitates the retraction and extension of the rain cover. In normal weather, the rain cover is retracted between the top cover and the inner cover for storage, providing good dust protection and preventing dust contamination. In rainy, snowy, or windy weather, the lifting plate extends the rain cover to protect the 3D laser scanner, preventing dust from contaminating the scanner's probe. This provides comprehensive rain, wind, and dust protection, which helps ensure the detection accuracy of the 3D laser scanner, extends its service life, and further improves monitoring efficiency.

[0027] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0028] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] refer to Figures 1 to 8 As shown in the figure, an embodiment of the present invention provides a three-dimensional scanning monitoring device for engineering foundations, including a frame 1. A support rod 4 is fixedly connected to the side wall of the frame 1. A support block 401 is fixedly connected to the side wall of the support rod 4. A fixing ring seat 402 is fixedly connected to the end of the support block 401. A support platform 3 is connected to the inside of the fixing ring seat 402 through a bearing. A three-dimensional laser scanner 8 is fixedly installed on the top of the support platform 3. The bottom of the support platform 3 is installed on the top of the frame 1 through a rotating adjustment component. A protective component is installed on the top of the support rod 4. The protective component includes a top cover 5 and an inner cover 501. A rain cover 6 is inserted and positioned between the top cover 5 and the inner cover 501. A lifting plate 601 is fixedly connected to the bottom of the rain cover 6. The rotating adjustment component includes a conical turntable 2. The top of the conical turntable 2 can drive the support platform 3 to rotate. The side wall of the conical turntable 2 can drive the lifting plate 601 to move up and down.

[0030] By adopting the above scheme, the rotation angle of the 3D laser scanner 8 can be easily adjusted through the cooperation of the rotating adjustment component and the support platform 3, expanding the detection range and making it more flexible in use, which is conducive to improving the efficiency of monitoring work. Furthermore, the cooperation of the rotating adjustment component and the protective components facilitates the retraction and extension of the rain cover 6. In normal weather, the rain cover 6 is retracted between the top cover 5 and the inner cover 501 for storage, providing good dust protection and avoiding dust contamination. In rainy, snowy, or windy weather, the lifting plate 601 drives the rain cover 6 to extend and cover the 3D laser scanner 8, preventing dust from contaminating the probe of the 3D laser scanner 8. It can provide all-round rainproof, windproof, and dustproof protection, which helps to ensure the detection accuracy of the 3D laser scanner 8, extend the service life of the 3D laser scanner 8, and further improve the efficiency of monitoring work.

[0031] Specifically, the bottom of the conical turntable 2 is connected to the top of the frame 1 via a bearing. A mounting groove 101 is provided on the top front of the frame 1. A motor 201 is fixedly connected to the bottom of the mounting groove 101. The output end of the motor 201 passes through the frame 1 and is fixedly connected to the bottom of the conical turntable 2. A toothed section 202 is fixedly connected to the side wall of the conical turntable 2.

[0032] The above solution effectively improves the stability of the conical turntable 2 mounting structure and facilitates the motor 201 to drive the conical turntable 2 to rotate.

[0033] Specifically, the two sides of the mounting groove 101 are connected by bearings to a main rotating rod 7 and an auxiliary rotating rod 701 respectively. A bevel gear 702 is sleeved and fixed on the main rotating rod 7. The toothed section 202 is meshed with the bevel gear 702. A toothed ring 703 is sleeved and fixed on the ends of both the main rotating rod 7 and the auxiliary rotating rod 701.

[0034] Using the above scheme, the conical turntable 2 can drive the main rotating rod 7 to rotate through the toothed section 202 and the bevel gear 702. The toothed ring 703 can easily cooperate with the toothed plate 604 on the lifting plate 601. That is, the main rotating rod 7 drives the toothed ring 703 to rotate, and the toothed ring 703 drives the toothed plate 604 to move up and down. In turn, the toothed plate 604 can drive the lifting plate 601 to move up and down, thereby realizing the contraction and extension of the protective cover, which is flexible in use.

[0035] Specifically, a fixing block 503 is fixedly connected to the top of the support rod 4. The fixing block 503 passes through the top cover 5, the rain cover 6, and the inner cover 501 from top to bottom. The top cover 5 and the inner cover 501 are both fixed to the fixing block 503 by bolts. A through hole 603 is opened in the middle of the rain cover 6. The through hole 603 is inserted into the fixing block 503. A storage groove 502 is provided between the top cover 5 and the inner cover 501. The rain cover 6 is placed in the storage groove 502. The rain cover 6 is made of transparent elastic silicone material with a pleated structure.

[0036] The above solution facilitates the installation and storage of the rain cover 6, preventing excessive dust accumulation on it during daily use. This also helps prevent dust contamination of the probe of the 3D laser scanner 8 when the rain cover 6 is extended, thereby improving the detection accuracy of the 3D laser scanner 8 during operation.

[0037] Specifically, toothed plates 604 are fixedly connected to both ends of the bottom of the lifting plate 601. The toothed plates 604 are meshed with one side of the toothed ring 703. A limiting rod 605 is fixedly connected to the toothed plate 604. The limiting rod 605 is attached to the other side of the toothed ring 703. The inner side of the limiting rod 605 slides up and down along the toothed ring 703.

[0038] With the above scheme, the rotation of the gear ring 703 can drive the gear plate 604 to move up and down, which in turn drives the lifting plate 601 and the rain cover 6 to move up and down, realizing the contraction and extension of the rain cover 6. It is convenient and flexible to use. The limiting rod 605 helps to ensure the stability of the connection structure between the gear plate 604 and the gear ring 703, which in turn helps to ensure the stability of the rain cover 6 when it moves up and down.

[0039] Specifically, the top of the conical turntable 2 is provided with an annular groove 203, and a first push block 204 is fixedly connected to the annular groove 203. The bottom of the support platform 3 and the conical turntable 2 are separated by a gap. The upper and lower side walls of the support platform 3 are respectively fixedly connected with a guide block 301 and a second push block 302, and the first push block 204 slides against the second push block 302.

[0040] Using the above scheme, when the rain cover 6 needs to be stored, the motor 201 drives the conical turntable 2 to rotate, and the conical gear 702 enters the tooth section 202 of the conical turntable 2. The toothed plate 604 moves upward along the toothed ring 703, driving the lifting plate 601 to gradually move upward until it squeezes and pushes the rain cover 6 to retract into the storage slot 502. At the same time, the conical turntable 2 drives the first push block 204 to rotate synchronously. The first push block 204 gradually approaches the second push block 302. When the rain cover 6 enters the storage slot 502, the first push block 204... 04. Rotate the device until it engages with the second push block 302, disengaging the toothed section 202 from the hammer gear. Finally, turn off the motor 201 to stop the conical turntable 2 from rotating, thus storing the rain cover 6. When it is necessary to adjust the angle of the 3D laser scanner 8, the motor 201 drives the conical turntable 2 to continue rotating. At this time, the conical turntable 2 will drive the first push block 204 to push the second push block 302, which in turn drives the support platform 3 to rotate, thereby adjusting the angle of the 3D laser scanner 8.

[0041] Specifically, the fixed ring seat 402 has a guide groove 403, and a stop block 405 is fixedly connected to the guide groove 403. The bottom of the guide block 301 slides along the guide groove 403. The guide block 301 and the stop block 405 are fixedly connected by a spring 404, which is placed in the guide groove 403.

[0042] Using the above scheme, when the angle of the 3D laser scanner 8 needs to be adjusted, the conical turntable 2 pushes the support platform 3 through the cooperation of the first push block 204 and the second push block 302. At this time, the rotating support platform 3 drives the guide block 301 to slide along the guide groove 403 and acts on the spring 404 to make it elastically stressed, ensuring the stability of the support platform 3 when it moves. When the 3D laser scanner 8 needs to be rotated in the reverse direction, the motor 201 drives the conical turntable 2 to rotate in the reverse direction. At this time, under the elastic force, the second push block 302 will stick to the first push block 204 and follow the first push block 204 to move in the reverse direction, making the adjustment flexible.

[0043] Specifically, a clearance groove 602 is provided between the rain cover 6 and the lifting plate 601, and the clearance groove 602 is engaged with the support block 401.

[0044] By adopting the above scheme, the rain cover 6 can be stably placed around the 3D laser scanner 8 for protection, avoiding the obstruction effect of the support block 401 on the rain cover 6.

[0045] Specifically, a controller 9 is fixedly installed on the mounting slot 101, and a wind, light and rain sensor 10 is fixedly installed on the top of the top cover 5. The wind, light and rain sensor 10 and the motor 201 are both electrically connected to the controller 9.

[0046] Using the above scheme, when the wind, light, and rain sensor detects rain or wind signals, it sends a signal to the controller 9. The controller 9 controls the motor 201 to start, which in turn causes the conical turntable 2 to rotate. This facilitates the downward movement and extension of the rain cover 6, providing all-around protection for the 3D laser scanner 8. When normal weather returns, the starting device causes the rain cover 6 to retract between the top cover 5 and the inner cover 501 for storage, making it flexible to use.

[0047] Working principle of the invention: When in use, the frame 1 is installed at the test point on the foundation, and the 3D laser scanner 8 scans and monitors the foundation. Under normal weather conditions, the rain cover 6 is stored in the storage slot 502 of the top cover 5 and the inner cover 501.

[0048] When the wind, light, and rain sensor detects rain or wind signals, it sends a signal to the controller 9. The controller 9 then starts the motor 201, which drives the conical turntable 2 to rotate. The toothed segment 202 meshes with the bevel gear 702, which in turn drives the main rotating rod 7 to rotate. The main rotating rod 7 then drives the toothed plate 604 to move downwards via the toothed ring 703, which in turn drives the lifting plate 601 and the rain cover 6 to move downwards. This causes the rain cover 6 to extend around the 3D laser scanner 8 for protection. At the same time, the first push block 204 moves away from the second push block 302 until the toothed segment 202 disengages from the bevel gear 702. At this point, the 3D laser scanner 8 on the support platform 3 is unaffected and will not rotate.

[0049] When the angle of the 3D laser scanner 8 needs to be adjusted, the conical turntable 2 pushes the support platform 3 through the cooperation of the first push block 204 and the second push block 302. At this time, the rotating support platform 3 drives the guide block 301 to slide along the guide groove 403 and acts on the spring 404 to make it elastically stressed, ensuring the stability of the support platform 3 when it moves. When the 3D laser scanner 8 needs to be rotated in the reverse direction, the motor 201 drives the conical turntable 2 to rotate in the reverse direction. At this time, under the elastic force, the second push block 302 will stick to the first push block 204 and move in the reverse direction with the first push block 204. The adjustment is flexible. At the same time, the conical gear 702 disengages from the tooth section 202 of the conical turntable 2. Therefore, when the support platform 3 is rotated and adjusted, the rain cover 6 will not move.
