Description

Technical Field

[0001] This utility model relates to the field of construction management and monitoring technology, and in particular to a BIM-based construction management and monitoring device. Background Technology

[0002] Building Information Modeling (BIM) is a new process approach for the design, construction, operation, and maintenance management of projects. BIM is the integration of information and models. As the core of BIM technology implementation, it is a database that parametrically expresses the engineering project and its functional attributes. It relies on computer systems as its technical support and networks as its data storage and interconnection platform. It achieves data transmission throughout the entire life cycle of the building and provides information support and sharing for all project stakeholders.

[0003] A construction safety monitoring device based on BIM smart construction site is disclosed in Chinese patent CN218825518U. The device includes a BIM simulation module connected to a BIM management module, a BIM management module connected to a BIM visualization module, and an execution device. The execution device consists of a control box and a support mounted on a base. The control box contains a wireless communication module and connected acquisition, audible and visual alarm, and motion control modules. The BIM management module is connected to the wireless communication module. The support rod meshes with a gear inside the support via a rack and pinion structure. A support motor, driven by the gear, is located outside the support. The base contains a drive motor and a rotating shaft. The drive motor is connected to the rotating shaft via a gear and belt structure. The motion control module is connected to the drive motor and the support motor. A panoramic camera, an air quality sensor, an infrared temperature sensor, and an audible and visual alarm are mounted on the upper part of the support rod.

[0004] The existing construction safety monitoring devices described above have significant shortcomings in on-site applications, particularly the lack of effective dust protection structures in their camera modules. In construction environments with high dust concentrations, large amounts of dust particles easily accumulate on the surface of the optical lenses, leading to decreased light transmittance and degraded image clarity, thus severely impacting the accuracy and reliability of the monitoring data. This problem not only reduces the usability of the video surveillance system but may also mask potential safety hazards due to degraded image quality, threatening the effectiveness of construction safety management.

[0005] To address the aforementioned issues, this utility model proposes a BIM-based construction management and monitoring device. Utility Model Content

[0026] Please see Figure 1-4 This utility model provides a technical solution: a BIM-based construction management monitoring device, including a movable base 1, a lifting platform 2 fixedly mounted on the upper surface of the movable base 1, a support plate 3 fixedly mounted on the telescopic end of the lifting platform 2, a fixed column 4 fixedly connected to the upper surface of the support plate 3, a monitor 5 mounted on the top of the fixed column 4, and a conical top cover 6 fixedly mounted on the top of the monitor 5. The movable base 1 facilitates the flexible movement of the entire device to different monitoring points; the lifting platform 2 can precisely adjust the monitoring height to adapt to different construction scenarios; the support plate 3 provides a stable installation platform; the fixed column 4 serves as the core support structure to ensure the stable installation of the monitor 5; and the conical top cover 6 provides both rain protection and optimized airflow guidance.

[0027] A rotating sleeve 7 is rotatably mounted on the outer side of the fixed column 4, and a monitoring component is installed on the outer side of the rotating sleeve 7. The monitoring component includes a cross 18, which is fixedly mounted on the outer side of the rotating sleeve 7. An alarm 19 is fixedly mounted on the upper end of the cross 18 away from the rotating sleeve 7, and an air quality sensor 20 is fixedly mounted on the lower end of the cross 18 away from the rotating sleeve 7. A connecting pipe 8 is fixedly mounted on the top of the rotating sleeve 7, and multiple air jets 9 are evenly arranged around the axis of the conical top cover 6 on the lower end of the conical top cover 6. The rotating sleeve 7 enables horizontal rotation scanning of the monitoring component; the cross 18 expands the monitoring range and rationally distributes the detection equipment; the alarm 19 provides real-time feedback on abnormal situations; the air quality sensor 20 collects environmental data from multiple directions; the connecting pipe 8 serves as a transmission component connecting the rotation and cleaning system; and the evenly distributed air jets 9 ensure thorough cleaning of the mirror surface dust without blind spots.

[0028] An airbag 10 is provided on the fixed column 4. Specifically, a storage groove 11 is provided on the side wall of the fixed column 4. One end of the airbag 10 is fixedly installed inside the storage groove 11, and the other end of the airbag 10 extends to the outside of the fixed column 4. A connecting plate 12 is fixedly installed on the end of the airbag 10 facing away from the fixed column 4. The connecting plate 12 is limitedly connected to the fixed column 4. Limiting rods 13 are slidably connected to both the upper and lower sides of the connecting plate 12. One end of the limiting rod 13 is fixedly connected to the outer wall of the fixed column 4, and the other end of the limiting rod 13 passes through the connecting plate 12 and is fixedly connected to a limiting block. A spring 14 is sleeved on the outside of the limiting rod 13. One end of the spring 14 abuts against the fixed column 4, and the other end of the spring 14 abuts against the connecting plate 12. The airbag 10 generates pulsed airflow through compression and expansion; the storage slot 11 provides storage space for the airbag 10 and protects it from damage; the connecting plate 12 stably connects the airbag 10 to the linkage mechanism; the limiting rod 13 ensures that the connecting plate 12 does not deviate in linear movement; the spring 14 provides reset elasticity and buffers impact; the limiting block prevents the connecting plate 12 from dislodging from the limiting rod 13.

[0029] The jet nozzle 9 is connected to the airbag 10. Specifically, an air tube 24 is fixed to the airbag 10, passing through the fixing post 4 and extending into the interior of the conical top cover 6. The jet nozzle 9 is connected to the air tube 24 via a connecting pipe. The air tube 24 efficiently delivers compressed air; the wiring inside the fixing post 4 prevents the air tube 24 from being exposed and damaged; the connection between the jet nozzle 9 and the air tube 24 forms a stable air path, ensuring continuous cleaning capability.

[0030] The connecting tube 8 is internally equipped with a linkage component for driving the movement of the airbag 10. The linkage component includes a second arc-shaped plate 16. Multiple second arc-shaped plates 16 are uniformly fixedly installed on the inner wall of the connecting tube 8 around its axis. A first arc-shaped plate 15 is fixedly installed on the side of the connecting plate 12 opposite to the airbag 10. All the second arc-shaped plates 16 abut against the first arc-shaped plate 15. The linkage component converts rotational motion into linear reciprocating motion; the second arc-shaped plates 16 provide periodic thrust as the connecting tube 8 rotates; the first arc-shaped plate 15 converts the rotational force into the compression force of the airbag 10, ensuring that the cleaning action and the monitoring scan are synchronized.

[0031] In this embodiment of the invention: an end cap 17 is fixedly installed at the top of the connecting pipe 8, and the end cap 17 is rotatably engaged with the fixing post 4. This prevents foreign objects from entering and reduces friction, while maintaining the stable relative rotation of the rotating sleeve 7 and the fixing post 4.

[0032] In this embodiment of the invention: a motor 21 is fixedly mounted on the upper end face of the support plate 3, a first gear 22 is fixedly mounted on the output shaft of the motor 21, and a second gear 23 is fixedly mounted on the outer side of the rotating sleeve 7. The first gear 22 and the second gear 23 are meshed and connected. The motor 21 provides stable power output; the meshing transmission between the first gear 22 and the second gear 23 ensures that the rotating sleeve 7 rotates at a uniform speed; the second gear 23 increases the torque, making the monitoring component rotate more smoothly.

[0033] Working principle:

[0034] After the monitoring system is positioned in the target area by moving the entire system using the movable seat 1, the height of the monitoring components and the monitor 5 off the ground is adjusted in multiple stages using the lifting platform 2.

[0035] During startup, the output shaft of motor 21 drives the first gear 22 to rotate, and through tooth meshing, the second gear 23 rotates in the opposite direction. This rotational motion is transmitted to the rotating sleeve 7 via the shaft system, causing it to rotate at a uniform speed. The cross 18 connected to the flange at the upper end of the rotating sleeve 7 rotates synchronously, enabling the four-way distributed monitoring components to achieve 360° monitoring. At the same time, the rotating sleeve 7 drives the connecting pipe 8 to rotate coaxially. At this time, the three sets of second arc-shaped plates 16, evenly distributed at 120° angles inside the pipe cavity, rotate with the shaft. When the flange of the second arc-shaped plate 16 contacts the flange of the first arc-shaped plate 15 fixed to the pipe wall, the first arc-shaped plate 15 is pushed radially inward under the wedge action, compressing the spring 14 to store energy. When the flange passes the contact surface, the spring 14 releases its elastic force, causing the first arc-shaped plate 15 to quickly return to its original position, thus forming a pulse-like mechanical motion. The connecting plate at the end of the first arc-shaped plate 15 transmits the reciprocating motion to the silicone airbag 10, causing it to contract regularly: during the expansion phase, ambient air is drawn in through a one-way valve, and during the compression phase, the airflow is delivered to the annularly distributed jet nozzles 9 through the pressure-resistant air pipe 24. The jet nozzles 9 are spaced apart on the edge of the monitor 5's protective cover, with their nozzles angled at 15° to the monitor 5's mirror surface. The pulsed airflow forms a spiral air curtain, effectively removing dust particles adhering to the mirror surface.

[0036] The cleaning system operates in conjunction with the rotating sleeve 7, and the rotational scanning of the cross 18 is strictly synchronized with the cleaning action, avoiding the monitoring blind spots and cleaning interference problems existing in traditional systems.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
