Description

Technical Field

[0001] This utility model relates to the field of material inventory technology, and in particular to a material inventory device for smart construction sites. Background Technology

[0002] In the construction and management of smart construction sites, the accuracy and efficiency of material inventory work play a crucial role in the smooth progress of the project, cost control, and rational allocation of resources. As an advanced material inventory device, the construction site 3D scanner has emerged. It can perform high-precision 3D scanning of various materials, building structures, and terrain on the construction site to obtain detailed spatial data information, thereby providing strong data support for multiple aspects such as project planning, construction progress monitoring, and quality assessment.

[0003] Existing smart construction site material inventory equipment often adopts a relatively fixed design in terms of mechanical structure. Its scanning angle is often determined at the initial installation of the equipment, making it difficult to adjust flexibly during the scanning process. For example, some traditional scanners use a fixed pan-tilt device to fix the scanner body. The rotation angle range of the pan-tilt is limited and the adjustment accuracy is not high. During data acquisition, it mainly relies on the scanner's own fixed laser emitting and receiving device to obtain point cloud data. Its technical principle is mostly based on the combination of laser ranging and angle measurement. By emitting a laser beam and receiving the reflected light, the distance between the scanning point and the scanner is calculated using the time difference or phase difference. Then, combined with the scanning angle information, the spatial coordinates of the scanning point are determined, thereby constructing a three-dimensional model.

[0004] Traditional smart construction site material inventory equipment has limited scanning angles, resulting in numerous scanning blind spots when facing complex and ever-changing construction site environments. It is impossible to fully cover the scanned object by adjusting the scanning angle, leading to incomplete 3D data. This seriously affects the accurate assessment of information such as the quantity and volume of materials and the structural features of buildings. To address these issues, a new smart construction site material inventory equipment is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a smart construction site material inventory device, which aims to improve the problem that the scanning angle is limited in the existing technology. When facing complex and ever-changing construction site environments, a large number of scanning blind spots occur, and it is impossible to fully cover the scanning object by adjusting the scanning angle. This results in incomplete three-dimensional data and seriously affects the accurate assessment of information such as the quantity, volume and structural features of materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart construction site material inventory device includes a camera, a dust cover fixedly connected to the side wall of the camera, a transparent plate fixedly connected inside the dust cover, a connecting plate fixedly connected to the side wall of the camera, a handle disposed between the cameras, an adjustment mechanism disposed between the cameras, an installation mechanism disposed on the side wall of the dust cover, and the adjustment mechanism including a receiving frame, the side wall of the receiving frame fixedly connected to the side wall of the handle, a fixing block disposed inside the receiving frame, the fixing block fixedly connected to the side wall of the connecting plate, a connecting column fixedly connected inside the fixing block, the side wall of the connecting column rotatably connected to the inside of the receiving frame, a fixing ring rotatably connected to the side wall of the connecting column, the side wall of the fixing ring fixedly connected to the side wall of the receiving frame, a worm gear fixedly connected to the side wall of the connecting column, a worm disposed inside the fixing block, the worm meshing with the worm gear, a fixing column fixedly connected to one end of the worm, and a motor fixedly connected inside the receiving frame, the output end of the motor being connected to the end of the fixing column away from the worm.

[0008] As a further description of the above technical solution:

[0009] The installation mechanism includes a first connecting block, one side wall of which is fixedly connected to the side wall of the dust cover, and a second connecting block is fixedly connected to one side wall of the first connecting block.

[0010] As a further description of the above technical solution:

[0011] The second sidewall of the connecting block is fixedly connected to the sidewall of the camera, and a locking post is fixedly connected inside the second connecting block;

[0012] As a further description of the above technical solution:

[0013] The connecting block is fixedly connected to a receiving column, and a limiting groove is formed inside the receiving column;

[0014] As a further description of the above technical solution:

[0015] The receiving column is slidably connected to a sliding column inside, and a receiving column is fixedly connected to the side wall of the sliding column;

[0016] As a further description of the above technical solution:

[0017] The sliding column sidewall is slidably connected to the inside of the locking column, and a guide column is fixedly connected to one end of the sliding column;

[0018] As a further description of the above technical solution:

[0019] A spring is installed inside the receiving column. One end of the spring is fixedly connected to the side wall of the sliding column, and the other end of the spring is fixedly connected to a load-bearing plate.

[0020] As a further description of the above technical solution:

[0021] The load-bearing plate is fixedly connected inside the receiving column.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when adjusting the angle of the camera, the starting motor drives the fixed column to rotate, and the rotation of the worm gear drives the worm wheel to rotate, causing the fixed block to deflect, thereby realizing the adjustment of the camera angle. It can scan objects and scenes in different positions and directions, avoiding scanning blind spots caused by a fixed angle, and thus more comprehensively obtaining three-dimensional data of the construction site.

[0024] 2. In this utility model, when disassembling and cleaning the dust cover, the bottom of the receiving column is moved backward, the spring deforms, and the sliding column separates from the locking column, completing the disassembly. When installing the dust cover, the inside of the receiving column is rotated, the spring loses its compression, and the sliding column moves forward, the sliding column engages with the locking column, completing the installation. This prevents dust from adhering to the lens surface, affecting image clarity and data accuracy, ensuring that the scanner acquires high-quality scanning data, and improving the stability and durability of the equipment.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a smart construction site material inventory device, including a camera 1. A dust cover 2 is fixedly connected to the side wall of the camera 1, and a transparent plate 3 is fixedly connected inside the dust cover 2 to prevent impurities from entering the camera 1 and damaging the delicate optical components and electronic circuits. The transparent plate 3 is made of high-transmittance, wear-resistant, and scratch-resistant high-quality optical material, which blocks external impurities without affecting the normal transmission of light, maximizing the brightness and clarity of the images acquired by the camera 1. A connecting plate 4 is fixedly connected to the side wall of the camera 1, and a handle 5 is provided between the cameras 1 for accurate scanning and inventory of materials, improving the convenience and comfort of operation. An adjustment mechanism is provided between the cameras 1, and an installation mechanism is provided on the side wall of the dust cover 2. The adjustment mechanism includes a receiving frame 6, and its structure is compact and reasonable, possessing good performance. With good stability and impact resistance, it can remain stable under complex working conditions, ensuring that all internal components operate according to a predetermined trajectory. The side wall of the receiving frame 6 is fixedly connected to the side wall of the handle 5. The receiving frame 6 is equipped with a fixing block 7, which is fixedly connected to the side wall of the connecting plate 4. The fixing block 7 is fixedly connected to the inside of the fixing block 7, and the side wall of the connecting column 8 is rotatably connected to the inside of the receiving frame 6. The side wall of the connecting column 8 is rotatably connected to a fixing ring 9, and the side wall of the fixing ring 9 is fixedly connected to the side wall of the receiving frame 6. The side wall of the connecting column 8 is fixedly connected to a worm gear 10. The fixing block 7 is equipped with a worm 11, which meshes with the worm gear 10. One end of the worm 11 is fixedly connected to a fixing column 12. The receiving frame 6 is fixedly connected to a motor 13, and the output end of the motor 13 is connected to the end of the fixing column 12 away from the worm 11. It can efficiently scan construction materials in different positions and directions.

[0034] When the device starts operating and the camera 1 needs to be adjusted, the motor 13 is first started to drive the fixed column 12 to rotate. The fixed column 12 has good rigidity and stability, ensuring that the power of the motor 13 is transmitted accurately and without loss, guaranteeing the continuity and reliability of subsequent actions. Simultaneously, the fixed column 12 drives the worm gear 11 to rotate. At this time, the worm gear 11 meshes with the worm wheel 10, and the rotation of the worm gear 11 drives the worm wheel 10 to rotate, thereby changing the direction and speed ratio of power transmission. This adapts the power to the operating characteristics of the worm wheel 10, ensuring the smoothness and precision of the entire adjustment action. It provides sufficient and stable driving force for subsequent actions, causing the fixed block 7 to deflect within the housing 6 around the connecting column 8, providing a stable mounting base and preventing the camera 1 from becoming loose or displaced during adjustment. This maintains the stability and accuracy of the captured image, enabling the camera 1 to adjust its angle and scan objects and scenes in different positions and directions, meeting complex and varied usage needs.

[0035] Reference Figures 4-5 The installation mechanism includes a connecting block 14, whose sidewall is fixedly connected to the sidewall of the dust cover 2, effectively preventing loosening due to excessive local stress and maintaining the integrity of the overall structure. A connecting block 25 is fixedly connected to the sidewall of connecting block 14, possessing excellent compressive and tensile strength. The sidewall of connecting block 25 is fixedly connected to the sidewall of the camera 1. A locking post 16 is fixedly connected inside connecting block 25, and a receiving post 17 is fixedly connected inside connecting block 14. A limiting groove 22 is formed inside the receiving post 17, and a sliding connection is made inside the receiving post 17. The sliding column 18 has a support column 19 fixedly connected to its side wall. The side wall of the sliding column 18 is slidably connected inside the locking column 16, which can generate strong friction and a stable mechanical locking effect, preventing the dust cover 2 from accidentally falling off during equipment operation and handling. One end of the sliding column 18 is fixedly connected to a guide column 20. A spring 21 is installed inside the receiving column 17. One end of the spring 21 is fixedly connected to the side wall of the sliding column 18, and the other end of the spring 21 is fixedly connected to a load-bearing plate 23. The load-bearing plate 23 is fixedly connected inside the receiving column 17, ensuring that the installation mechanism operates flexibly and efficiently.

[0036] When the dust cover 2 needs to be disassembled and cleaned after the equipment is in operation, firstly, the receiving column 19 is moved backward at the bottom inside the limiting groove 22 to ensure that the moving trajectory of the receiving column 19 is not affected by deviation or shaking, thus preventing interference with disassembly. This also limits the range of motion for subsequent actions. The movement of the receiving column 19 drives the sliding column 18 to move inside the receiving column 17. Then, the receiving column 19 is rotated until it engages with the groove inside the limiting groove 22. At this time, the spring 21 is compressed by the sliding column 18 and deforms, efficiently converting its stored elastic potential energy, causing the sliding column 18 to separate from the locking column 16, thus completing the disassembly of the dust cover 2. When the dust cover 2 needs to be installed during equipment operation, firstly, the receiving column 19 is rotated inside the limiting groove 22. The spring 21 loses its compression and moves the sliding column 18 forward, causing the sliding column 18 to engage with the locking column 16, providing a stable connection for the dust cover 2 and ensuring that the dust cover 2 will not accidentally fall off during equipment operation, thus completing the installation of the dust cover 2.

[0037] Working principle: When the device starts running and the angle of camera 1 needs to be adjusted, the motor 13 is started first to drive the fixed column 12 to rotate. At the same time, the fixed column 12 drives the worm gear 11 to rotate. At this time, the worm gear 11 meshes with the worm wheel 10. The rotation of the worm gear 11 drives the worm wheel 10 to rotate, causing the fixed block 7 to deflect inside the housing 6 with the connecting column 8 as the axis, thereby realizing the angle adjustment of camera 1, which can scan objects and scenes in different positions and directions.

[0038] When the dust cover 2 needs to be disassembled and cleaned after the equipment is in operation, first move the bottom of the receiving column 19 backward inside the limiting groove 22. The movement of the receiving column 19 drives the sliding column 18 to move inside the receiving column 17. Then rotate the receiving column 19 until it engages with the groove inside the limiting groove 22. At this time, the spring 21 is squeezed by the sliding column 18 and deforms, causing the sliding column 18 to separate from the locking column 16, thus completing the disassembly of the dust cover 2. When the dust cover 2 needs to be installed during equipment operation, first rotate the receiving column 19 inside the limiting groove 22. The spring 21 loses its compression and moves the sliding column 18 forward, causing the sliding column 18 to engage with the locking column 16, thus completing the installation of the dust cover 2.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
