Description

Technical Field

[0001] This utility model relates to the field of gimbal stabilization technology, and more specifically, to a gimbal stabilization structure for a BIM model scanner. Background Technology

[0002] With the continuous development of computer technology and digital twin technology, the construction industry is inevitably moving towards intelligence, digitalization, and visualization.

[0003] The development of BIM technology has promoted the digital integration of the physical building and the virtual building space. BIM technology can integrate engineering information, processes, and resources from different stages throughout the building's lifecycle into a single 3D model. In the design phase, BIM integrates architecture, structure, MEP (Mechanical, Electrical, and Plumbing) systems, coordinating the needs of designers from all parties. In the construction phase, BIM uses 3D digital technology to simulate the building's real-world information, providing a coordinated and internally consistent information model for both design and construction teams, improving building quality and reducing construction costs. In the building operation and maintenance phase, BIM can be integrated with operation and maintenance management systems for space management, facility management, emergency management, energy conservation and emission reduction management, etc., reducing operation and maintenance costs.

[0004] Existing BIM model scanners are typically used on drones, but their use has the following drawbacks:

[0005] During horizontal rotation and pitch adjustment, mechanical transmission components are prone to shaking, which can cause deviations in the scanning angle and affect modeling accuracy.

[0006] When working at heights or using the scanner for extended periods, dust and water vapor can easily accumulate on the scanner lens. Traditional manual cleaning methods are complex and may reduce work efficiency due to downtime for maintenance.

[0007] Angle adjustment relies on manual operation, making it difficult to accurately control the scanning direction. Especially in complex building environments, frequent angle adjustments are required, resulting in low scanning efficiency.

[0008] Therefore, a gimbal stabilization structure for BIM model scanners is proposed. Utility Model Content

[0009] In order to overcome the above-mentioned defects of the prior art, the present invention provides a gimbal stabilization structure for a BIM model scanner to solve the problems mentioned in the background art.

[0010] To achieve the above objectives, this utility model provides the following technical solution: a gimbal stabilization structure for a BIM model scanner, comprising a top box, a base plate disposed at the top of the top box, a rotating component mounted at the bottom of the top box, a rotating component rotatably connected to the bottom of the rotating component, a BIM model scanner body fixedly connected to the rotating component, an adjustment component engaged at one end of the rotating component, and a cleaning component that cooperates with the BIM model scanner body disposed at the bottom of the top box.

[0011] Preferably, the rotating assembly includes a motor, a rotating rod, and a fixing frame. The motor is installed inside the top box, the output end of the motor is connected to the rotating rod, and the bottom end of the rotating rod is equipped with a fixing frame.

[0012] Preferably, the rotating assembly includes a rotating shaft and a gear. The rotating shaft is rotatably mounted on a fixed frame and is connected to one end of the BIM model scanner body. A gear is coaxially arranged at one end of the rotating shaft.

[0013] Preferably, a support plate is provided at the bottom of one side of the fixing frame, and limit plates are provided parallel to each other at both ends of the support plate. A sliding groove is formed between the support plate and the limit plates, and one end of the adjusting component is slidably connected to the sliding groove.

[0014] Preferably, the adjustment assembly includes a first electric push rod and a toothed plate. The first electric push rod is mounted on one side of the fixed frame, and the telescopic end of the first electric push rod is connected to a toothed plate that is slidably connected to a slide groove. The top end of the toothed plate is meshed with a gear.

[0015] Preferably, the cleaning assembly includes a second electric actuator and a cleaning brush, wherein the second electric actuator is installed inside the top box, and the cleaning brush is installed at the telescopic end of the second electric actuator.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. The BIM model scanner body can be rotated 360° horizontally by rotating components to expand the scanning range. The adjustment component drives the rotating shaft to rotate, realizing the tilt angle adjustment of the scanner. Combined with horizontal rotation, it can complete all-round scanning to meet the needs of complex scenarios.

[0018] 2. The cleaning component and the rotating component are linked. When the scanner is placed horizontally, the cleaning brush can automatically wipe the dust and water mist on the lens surface during rotation, avoiding scanning errors caused by lens contamination during high-altitude operations and improving data clarity.

[0019] 3. The groove formed by the support plate and the limiting plate limits and guides the movement of the gear plate, ensuring smooth gear transmission, reducing shaking during adjustment, and improving angle control accuracy. The electric actuator drive has the characteristics of controllable stroke and stable thrust, realizing automated control of scanning angle adjustment and cleaning action, reducing human operation error, and improving equipment reliability.

[0025] 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.

[0026] As attached Figure 1-4 The diagram shows a gimbal stabilization structure for a BIM model scanner, comprising a top box 1, a base plate 2 at the top of the top box 1, a rotating component 3 at the bottom of the top box 1, a rotating component 4 rotatably connected to the bottom of the rotating component 3, a BIM model scanner body 5 fixedly connected to the rotating component 4, an adjustment component 6 engaged at one end of the rotating component 4, and a cleaning component 7 that cooperates with the BIM model scanner body 5 at the bottom of the top box 1.

[0027] In practical implementation, the base plate 2 provides a stable support surface for the whole, allowing the base plate 2 to be connected and fixed to the UAV. During operation, the rotation component 3 allows the BIM model scanner body 5 to rotate, facilitating scanning in any direction within the plane. The operation of the adjustment component 6 causes the rotation component 4 to rotate, enabling the BIM model scanner body 5 to adjust its pitch. This, combined with the operation of the rotation component 3, allows for omnidirectional scanning. Furthermore, the cleaning component 7 ensures that when the BIM model scanner body 5 is horizontal, the operation of the rotation component 3 causes the lens of the BIM model scanner body 5 to rub against the cleaning component 7 for automatic cleaning. This prevents the lens from being covered by fog during high-altitude scanning and improves the clarity of the scan.

[0028] The rotating assembly 3 includes a motor 301, a rotating rod 302, and a fixing frame 303. The motor 301 is installed inside the top box 1. The output end of the motor 301 is connected to the rotating rod 302, and the fixing frame 303 is installed at the bottom end of the rotating rod 302.

[0029] In practice, the motor 301 operates, causing the rotating rod 302 to rotate, which in turn causes the BIM model scanner body 5 mounted on the fixed frame 303 to rotate horizontally. Thus, the scanner can rotate at any angle in the horizontal direction, expanding the scanning range and improving the flexibility of scanning.

[0030] The rotating assembly 4 includes a rotating shaft 401 and a gear 402. The rotating shaft 401 is rotatably mounted on the fixed frame 303. The rotating shaft 401 is connected to one end of the BIM model scanner body 5. The gear 402 is coaxially arranged at one end of the rotating shaft 401.

[0031] A support plate 8 is provided at the bottom of one side of the fixed frame 303. Limiting plates 9 are provided parallel to each other at both ends of the support plate 8. A sliding groove is formed between the support plate 8 and the limiting plates 9. One end of the adjusting component 6 is slidably connected to the sliding groove.

[0032] The adjustment assembly 6 includes a first electric push rod 601 and a toothed plate 602. The first electric push rod 601 is installed on one side of the fixed frame 303. The telescopic end of the first electric push rod 601 is connected to the toothed plate 602, which is slidably connected to the slide groove. The top end of the toothed plate 602 is meshed with the gear 402.

[0033] In practice, by extending and retracting the first electric push rod 601, the toothed plate 602 can be moved, thereby causing the gear 402 to drive the rotating shaft 401 to rotate, thus enabling the BIM model scanner body 5 to perform pitch movement, thereby realizing the adjustment of the vertical pitch angle of the scanner body.

[0034] The cleaning component 7 includes a second electric push rod 701 and a cleaning brush 702. The second electric push rod 701 is installed inside the top box 1, and the cleaning brush 702 is installed on the telescopic end of the second electric push rod 701.

[0035] In practice, the second electric push rod 701 is installed inside the top box 1, and its telescopic end is connected to the cleaning brush 702. When cleaning is required, the second electric push rod 701 extends, driving the cleaning brush 702 to move downward. The lens of the BIM model scanner body 5 rotates in conjunction with the rotating component 3, which enables friction between the lens and the cleaning brush 702, thereby removing dust and water mist from the lens surface and improving the clarity of the scan by the BIM model scanner body 5. After cleaning is completed, the second electric push rod 701 retracts, and the cleaning brush 702 returns to its initial position.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
