Description

Technical Field

[0001] The utility model relates to the technical field of BIM construction engineering application, in particular to a construction site monitoring device based on a BIM model. Background Art

[0002] BIM model, or Building Information Model, is a process of creating and managing building information throughout the entire life cycle of planning, design, construction, and operation and maintenance stages of construction projects and facilities. It uses three-dimensional digital technology to create a virtual model that contains rich information. This information includes not only geometric shapes, but also non-geometric attributes such as building materials, performance parameters, and cost estimates.

[0003] Regarding a construction site monitoring device based on the BIM model with publication number CN221198350U, the utility model is equipped with a series of structures to facilitate the control of the automatic turnover of the laser scanner for overall scanning. The three-dimensional laser scanner is used to scan the components to be assembled on the construction site and the scanning information is transmitted to the BIM model system for corresponding analysis, recording, and prompting. It is convenient to quickly and automatically adjust the scanning height, improve the convenience of adjustment, and facilitate the protection of the three-dimensional laser scanner and dust protection and cleaning work without affecting the scanning work, reducing the risk of being affected by dust obstruction and damage by accidental flying objects, and improving the safety and stability of use.

[0004] Although the above technical solution can protect and clean the 3D laser scanner without affecting the scanning work, it has defects. When the transparent protective plate is wiped with a wet wipe, water stains will remain on the transparent protective plate. Even if dry wipes are used, wiping marks will be left, which will affect the scanning effect of the 3D laser scanner. Therefore, we propose a construction site monitoring device based on the BIM model to solve this problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-5 , a construction site monitoring device based on the BIM model includes a main board 1, a circular hole is opened on the top of the main board 1, a dust box 2 is slidably installed on the bottom of the main board 1, and the same rotating shaft 3 is rotatably installed between the top inner wall and the bottom inner wall of the dust box 2. The top end of the rotating shaft 3 extends to the outside of the dust box 2 and is fixedly sleeved with a gear 4. An internal gear ring 5 is provided on the inner wall of the circular hole. The gear 4 is meshed with the internal gear ring 5. The same worm 6 is rotatably installed between the front and rear inner walls of the dust box 2. A worm gear 7 is provided on the outer fixed sleeve of the rotating shaft 3. The worm gear 6 is meshed with the worm gear 7. The same pressing plate 9 is slidingly and sealably installed between the inner walls of the dust box 2. The outer fixed sleeve of the worm gear 6 is provided with two cams 8. The cam 8 is fixedly connected to the pressing plate 9. The front side of the dust box 2 is connected to the dust head 10, and the rear side of the dust box 2 is fixedly mounted with a motor, and the output shaft of the motor is fixedly connected to the worm gear 6.

[0027] like Figure 3 As shown, spring telescopic rods 11 are fixedly installed at the four corners of the inner wall of one side of the dust box 2, and one end of the spring telescopic rod 11 is fixedly connected to the pressure plate 9. L-shaped plates 12 are fixedly installed on the top inner wall and the bottom inner wall of the dust box 2. The sliding seal of the pressure plate 9 is lifted on the outside of the two L-shaped plates 12. The spring telescopic rod 11 resets the pressure plate 9 and cooperates with the cam 8 to drive the pressure plate 9 to reciprocate. The L-shaped plate 12 guides the pressure plate 9, and an air hole is opened on the top of the dust box 2. The air hole is located on the right side of the moving range of the pressure plate 9, so that the pressure plate 9 can reciprocate.

[0028] like Figure 3 and Figure 4 As shown, a pan-tilt head 13 is fixedly provided at the bottom of the dust collection box 2, and a three-dimensional laser scanner 14 is fixedly connected to the movable end of the pan-tilt head 13. The pan-tilt head 13 is an important component of the monitoring system. It provides flexible and changeable viewing angle adjustment capabilities, making monitoring instruments and monitoring more efficient and comprehensive.

[0029] like Figure 3 As shown, a collecting box 15 is fixedly connected to the left side of the dust box 2, and a filter screen 16 is provided on one side of the collecting box 15. The bottom of the dust box 2 is arranged in a bucket shape, and a waste outlet is provided at the bottom of the dust box 2. A control valve 17 is provided at the waste outlet. The setting of the filter screen 16 allows the air drawn into the collecting box 15 by the dust box 2 to be discharged to the outside, while the dust remains in the collecting box 15. When the entire device stops working, the waste outlet is opened by the control valve 17 to discharge the dust.

[0030] like Figure 3 and Figure 4 As shown, a power supply 18 is provided at the bottom of the dust collection box 2 , and the power supply 18 is used to supply power to the motor, the control valve 17 , the pan-tilt platform 13 and the three-dimensional laser scanner 14 .

[0031] like Figure 3 and Figure 4 As shown, there is a conduit connecting the collection box 15 and the dust collection box 2, and a one-way valve is provided on the conduit and the dust collection head 10. The flow direction of the one-way valve on the conduit is from the dust collection box 2 to the collection box 15, and the flow direction of the one-way valve on the dust collection head 10 is external to the dust collection box 2. The setting of the one-way valve limits the moving direction of the airflow, so that the reciprocating pressure plate 9 can generate an air pressure difference to suck the external dust into the dust collection box 2.

[0032] like Figure 2 and Figure 3 As shown, a T-shaped annular groove 19 is provided at the bottom of the main board 1, and a sliding member 20 is fixedly installed on the top of the dust collector box 2. The sliding member 20 is slidably installed in the T-shaped annular groove 19. The sliding member 20 moves in the T-shaped annular groove 19 to support and guide the movement of the dust collector box 2.

[0033] like Figure 1 and Figure 2 As shown, the four bottom corners of the mainboard 1 are provided with snap-in grooves 21, and the four top corners of the mainboard 1 are fixedly installed with lifting structures 22. The lifting structures 22 facilitate the lifting equipment to lift the mainboard 1 above the construction site. The setting of the snap-in grooves 21 facilitates the insertion into the bracket, and the mainboard 1 can also be fixed above the construction site.

[0034] The working principle of the present utility model is as follows: the motor is started, and the output shaft of the motor drives the worm 6 and the two cams 8 to rotate at high speed. The cam 8 drives the pressure plate 9 to reciprocate horizontally by cooperating with the spring telescopic rod 11, so that an air pressure difference is continuously generated in the dust collection box 2. The dust near the three-dimensional laser scanner 14 enters the dust collection box 2 through the dust collection head 10, and is then discharged into the collection box 15 through the duct, thereby realizing dust absorption of the area around the three-dimensional laser scanner 14. The worm 6 drives the rotating shaft 3 and the gear 4 to rotate together by meshing with the worm wheel 7. The gear 4 drives the dust collection box 2 to perform a circular motion by meshing with the inner gear ring 5, thereby driving the three-dimensional laser scanner 14 to automatically rotate and perform overall scanning. The three-dimensional laser scanner 14 is used to scan the components to be assembled at the construction site and the scanning information is transmitted to the BIM model system for corresponding analysis and recording.
