Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a building monitoring device based on BIM technology. Background Art

[0002] The core of BIM is to establish a virtual three-dimensional model of the construction project and use digital technology to provide this model with a complete and actual construction project information database. This information database not only contains geometric information, professional attributes and status information describing the building components, but also contains status information of non-component objects (such as space and motion behavior). With the help of this three-dimensional model containing construction project information, the degree of information integration of the construction project is greatly improved, thus providing a platform for engineering information exchange and sharing for the stakeholders of the construction project.

[0003] In the prior art, during construction, it is necessary to collect information on the working conditions of completed buildings on site, and combine it with BIM technology modeling comparison to verify the data of completed buildings. In this process, it is necessary to use a shooting device to shoot the construction site. However, there is a lot of dust on the construction site, and when there is less rainfall, rain or dust is easy to adhere to the lens of the shooting device. Although the prior art sets an auxiliary lens at the lens, the clear shooting of the lens is ensured by cleaning the auxiliary lens, but the auxiliary lens is usually fixed in front of the lens, and the collection work needs to be carried out continuously. If the auxiliary lens is cleaned during the collection process, it will result in blocking the continuous shooting and collection work of the lens. Summary of the invention

[0018] The present invention will be further described below in conjunction with the accompanying drawings: See attached Figure 1-8 In this embodiment, a building monitoring device based on BIM technology includes a base 1, a camera 22 and a universal wheel 2. The lower end of the base 1 is equipped with a universal wheel 2. The upper end of the base 1 is rotatably connected to a support column 3. The upper end of the support column 3 is fixedly connected to a transmission box 7. A transmission mechanism is provided in the transmission box 7. The transmission box 7 is used to protect the transmission mechanism, so that the device can be used in weather with less rainfall. The side wall of the support column 3 is fixedly connected to a gear 2 6. The upper end of the base 1 is also fixedly connected to a motor 4, and the output end of the motor 4 is fixedly connected to a gear 5, and the gear 5 is meshed with the gear 2 6. A light shield 10 is fixedly connected to the top of the transmission box 7, and a transparent glass cover 11 is arranged inside the light shield 10. The camera 22 is installed inside the transparent glass cover 11. The light shield 10 is provided with an opening 9. The motor 4 drives the gear 2 6 to rotate, and the gear 2 6 drives the transmission box 7 to rotate. The rotation of the transmission box 7 can drive the camera 22 to rotate, thereby increasing the angle range of the camera 22 for shooting the construction site. The transparent glass cover 11 can protect the camera 22. Due to the tight construction period or when the camera 22 is shooting, In weather with little rainfall or when there is a lot of dust in the air, the shooting work of the camera 22 needs to be continued. At this time, the transparent glass cover 11 can be rotated and the cleaning mechanism can continuously clean the transparent glass cover 11, so that the camera 22 will not have any reduction in shooting quality due to the adhesion of rain or dust. A protective box 8 is fixedly connected to the side wall of the sunshade 10, and a cleaning mechanism is provided inside the protective box 8. The sunshade 10 not only protects the transparent glass cover 11, but also blocks rain and light, thereby minimizing the impact of refraction and reflection on the shooting quality of the camera 22.

[0019] The transmission mechanism includes a motor 2 13, a chassis 17, a gear 3 14 and a gear 4 16. The motor 2 13 is fixedly connected to the bottom wall inside the transmission box 7. The gear 3 14 is fixedly connected to the output end of the motor 2 13. The end of the gear 3 14 away from the motor 2 13 is also fixedly connected to a connecting shaft 19. The other end of the connecting shaft 19 passes through the transmission box 7 and extends to the outside and is fixedly connected to a gear 5 43. The gear 5 43 is a half gear. A support seat 15 is also fixedly connected to the bottom wall inside the transmission box 7. The gear 4 16 is rotatably connected to the support seat 15, and the gear 4 16 The gear 4 16 is meshed with the gear 3 14, and the upper end of the gear 4 16 is coaxially fixed with the chassis 17, and the chassis 17 is provided with a clamping assembly. The motor 2 13 rotates to drive the gear 3 14 to rotate, the gear 3 14 drives the gear 4 16 to rotate, and the gear 4 16 drives the chassis 17 to rotate. The chassis 17 can subsequently drive the transparent glass cover 11 to rotate, so that the transparent glass cover 11 can be continuously cleaned, so that the camera 22 can maintain a clear shooting effect in weather with less rainfall or when there is a lot of dust in the air.

[0020] The clamping assembly includes a clamping seat 26, a spring 1 37 and a rubber column 36. The clamping seat 26 is provided with four equiangular rings arranged on the upper end of the chassis 17. The clamping seat 26 is fixedly connected with a sleeve 1 34. A sleeve 2 35 is slidably connected to the clamping seat 26 at a position opposite to the sleeve 1 34. The front side of the end of the sleeve 2 35 and the sleeve 1 34 close to each other is embedded with a rubber column 36. The end of the sleeve 2 35 away from the sleeve 1 34 is fixedly connected with a magnet 54. The outer sleeve 2 35 is sleeved with a spring 1 37. Under the action of the spring 1 37, the sleeve 2 35 is pushed to move in the direction close to the sleeve 1 34. The transparent glass cover 11 can be pressed against the rubber column 36. The inner and outer side walls are clamped, so that the transparent glass cover 11 can be fixed, which is convenient for driving the transparent glass cover 11 to rotate later. The spring 1 37 is fixed between the magnet 54 and the side wall of the clamping seat 26. One side of the clamping seat 26 is located on the chassis 17 and is also fixed with an auxiliary plate 27. The auxiliary plate 27 is installed with an electromagnet 38. A connecting rod 28 is fixed at the middle position of the chassis 17. When the transparent glass cover 11 needs to be removed, the electromagnet 38 can be energized to make the electromagnet 38 attract the magnet 54, thereby overcoming the resistance of the spring 1 37, so that the sleeve 2 35 is away from the sleeve 1 34, so that the transparent glass cover 11 can be removed.

[0021] The transmission mechanism also includes movable teeth 24, cylinder two 29 and movable plate 25. A plurality of fixed teeth are fixedly connected to gear three 14, and a plurality of slide grooves 30 are provided at the edge of gear three 14. The movable teeth 24 are respectively slidably connected inside the slide grooves 30. A slide rod 31 is fixedly connected to one end of the movable teeth 24, and an end of the slide rod 31 away from the movable teeth 24 is jointly fixedly connected to the movable plate 25. A bracket one 18 is fixedly connected to the upper end of the gear three 14, and a cylinder two 29 is fixedly connected to the interior of the bracket one 18. A movable column 55 is fixedly connected to the piston rod of the cylinder two 29. The movable column 55 is slidably connected to the gear three 14, and the other end of the movable column 55 passes through the gear three 14 and is fixedly connected to the movable plate 25.

[0022] The present application has two cleaning modes for the transparent glass cover 11, one is a continuous cleaning mode, and the other is an intermittent cleaning mode. The continuous cleaning mode is used when encountering weather with less rainfall or when there is a lot of dust in the air, that is, the fixed teeth and the movable teeth 24 are both in a meshing connection with the gear four 16, so that the gear four 16 can rotate continuously, thereby driving the transparent glass cover 11 to rotate continuously, and continuously cleaning the transparent glass cover 11, thereby ensuring the clarity and transparency of the transparent glass cover 11 to the greatest extent, thereby ensuring the shooting quality of the camera 22.

[0023] Under normal working conditions, since the transparent glass cover 11 is not easily adhered to dust or contacted with water, the use of the intermittent cleaning mode can reduce the rotation of the transparent glass cover 11, thereby reducing the impact of the rotating transparent glass cover 11 on the camera 22 when shooting, and improving the shooting effect of the camera 22. At this time, the movable plate 25 can be driven downward by the cylinder 29 through the movable column 55, and the movable plate 25 drives the movable tooth 24 to move downward through the slide rod 31, so that the movable tooth 24 is disengaged from the fixed tooth. When the gear three 14 rotates, only the fixed tooth and the gear four 16 remain meshed and connected, so that the gear four 16 can be driven to rotate intermittently, and the gear four 16 can subsequently drive the transparent glass cover 11 to rotate intermittently, so as to intermittently clean the transparent glass cover 11.

[0024] The upper end of the transmission box 7 is provided with a through hole, and a connecting plate 53 is provided at the through hole. The lower end of the connecting plate 53 is fixedly connected to the upper end of the connecting rod 28. The side wall of the transparent glass cover 11 is movably engaged in the gap between the connecting plate 53 and the transmission box 7, and the bottom end of the transparent glass cover 11 extends to the inside of the transmission box 7 and is movably engaged with the clamping seat 26. An adjustment component is provided inside the transparent glass cover 11. The adjustment component includes a cylinder 21 and a bracket 23. The bracket 23 and the cylinder 21 are both fixedly connected to the connecting plate 53. The camera 22 is rotatably mounted on the bracket 23. The piston rod of the cylinder 21 is fixedly connected to the bottom end of the camera 22. The cylinder 21 can be used to drive the camera 22 to rotate on the bracket 23, thereby adjusting the pitch angle of the camera 22 to adapt to more shooting scenes.

[0025] The cleaning mechanism includes a cleaning sponge 46, a sleeve rod 40 and a cylinder three 49. A long groove is opened on the side wall of the light shield 10, and the cleaning sponge 46 is slidably connected to the long groove. The width of the long groove is smaller than the thickness of the cleaning sponge 46, so that when the cleaning sponge 46 is subsequently pulled through the long groove, the moisture in the cleaning sponge 46 can be squeezed out, thereby ensuring the water absorption effect of the cleaning sponge 46.

[0026] One end of the cleaning sponge 46 fits tightly with the transparent glass cover 11, and the cleaning sponge 46 can not only absorb water but also wipe away dust. A bracket 20 is fixedly connected to the side wall of the light shield 10, and a sleeve rod 40 is slidably connected to the bracket 20, and a clamping seat 48 is fixedly connected to the end of the sleeve rod 40 close to the light shield 10, and bolts 44 are respectively threadedly installed on the two side walls of the clamping seat 48, and the ends of the bolts 44 close to each other are fixedly connected to a pressure plate 45, and the end of the cleaning sponge 46 away from the light shield 10 is movably installed between the two pressure plates 45, and a spring 241 is sleeved on the outside of the sleeve rod 40, and the spring 241 is fixedly connected between the clamping seat 48 and the bracket 20. By rotating the bolt 44, the two pressure plates 45 are driven close to each other, so that one end of the cleaning sponge 46 can be clamped and fixed.

[0027] A cylinder three 49 is fixedly connected to the bottom end of the bracket two 20, and a connecting seat 50 is abutted below the cylinder three 49. A clamping block is fixedly connected to the rear end side wall of the connecting seat 50. A guide groove 52 is opened on the clamping seat 48, and a guide rod 51 is fixedly connected to the guide groove 52. The clamping block is slidably connected to the guide rod 51. A spring three 56 is sleeved on the outer side of the guide rod 51, and the spring three 56 is fixedly connected between the clamping block and the guide groove 52. A rack 42 is provided below the connecting seat 50, and the rack 42 is meshed with the gear five 43. A travel switch 47 is fixedly connected to the upper end of the clamping seat 48, and an electronic relay 39 is installed on the side wall of the bracket two 20.

[0028] After the cleaning sponge 46 absorbs water for a period of time, its water absorption capacity is greatly reduced due to being in a saturated state. Therefore, it is necessary to squeeze out the water inside the cleaning sponge 46. When the gear three 14 rotates, it will drive the connecting shaft 19 to rotate synchronously. The connecting shaft 19 will drive the gear five 43 to rotate. When the gear five 43 rotates, it will drive the rack 42 to move. The rack 42 drives the holder 48 to move through the connecting seat 50, so that one end of the cleaning sponge 46 can be driven to slide in the long groove, and the long groove squeezes out the water in the cleaning sponge 46. Since the gear five 43 is a half gear, when the gear five 43 rotates until it is no longer meshed with the rack 42, the holder 48 is pushed to move under the action of the spring two 41, so that the holder 48 drives the cleaning sponge 46 to move in the direction close to the transparent glass cover 11 again, so that the cleaning sponge 46 is tightly fitted with the transparent glass cover 11 again. Furthermore, since the cleaning sponge 46 will be saturated after absorbing water for a period of time, there is no need to frequently pull the cleaning sponge 46 to squeeze it, otherwise the water absorption and cleaning effect of the transparent glass cover 11 will be reduced. Therefore, it is necessary to squeeze the cleaning sponge 46 for a period of time before squeezing the cleaning sponge 46 again. After the cleaning sponge 46 completes a squeezing action, the cleaning sponge 46 is reset and tightly fits the transparent glass cover 11. At this time, the travel switch 47 on the holder 48 is in contact with the light shield 10, and the travel switch 47 will control The piston rod of the control cylinder three 49 is retracted, and the connecting seat 50 moves upward under the action of the spring three 56, so that the rack 42 and the gear five 43 are separated. When the gear five 43 rotates, the connecting seat 50 cannot be driven to move by the rack 42, and the cleaning sponge 46 cannot be squeezed and dehydrated again within a certain period of time. After a certain period of time, the electronic relay 39 will automatically control the cylinder three 49 to move again, so that the piston rod extends and drives the connecting seat 50 to move downward, so that the rack 42 and the gear five 43 are meshed, and the cleaning sponge 46 is squeezed and dehydrated next time.

[0029] An annular groove 33 and a drainage groove 12 are also provided at the upper end of the transmission box 7. The annular groove 33 and the drainage groove 12 are connected. The water squeezed and dehydrated by the cleaning sponge 46 will be discharged through the annular groove 33 and the drainage groove 12. A water guide pad 32 is also sleeved on the outer wall of the transparent glass cover 11. The annular groove 33 is located between the water guide pad 32 and the sunshade 10. The water guide pad 32 prevents water from entering the transmission box 7 and affecting the operation of the transmission mechanism.

[0030] Working principle: The motor 1 4 drives the gear 2 6 to rotate, and the gear 2 6 drives the transmission box 7 to rotate. The rotation of the transmission box 7 can drive the camera 22 to rotate, and adjust the horizontal angle of the camera 22. The cylinder 1 21 can drive the camera 22 to rotate on the bracket 3 23, thereby adjusting the pitch angle of the camera 22; During daily operation, the cylinder 29 drives the movable plate 25 to move downward through the movable column 55, and the movable plate 25 drives the movable tooth 24 to move downward through the slide rod 31, so that the movable tooth 24 is disengaged from the fixed tooth. When the gear 3 14 rotates, only the fixed tooth and the gear 4 16 are kept in meshing connection, thereby driving the gear 4 16 to rotate intermittently. The gear 4 16 can subsequently drive the transparent glass cover 11 to rotate intermittently, and the transparent glass cover 11 is intermittently cleaned to reduce the rotation of the transparent glass cover 11, thereby reducing the influence of the rotating transparent glass cover 11 on the camera 22 when shooting, and improving the shooting effect of the camera 22; When encountering light rainfall or high dust content in the air, the continuous cleaning mode is used, and the fixed teeth and the movable teeth 24 are both in meshing connection with the gear four 16, so that the gear four 16 can rotate continuously, thereby driving the transparent glass cover 11 to rotate continuously, and continuously cleaning the transparent glass cover 11, thereby ensuring the clarity and transparency of the transparent glass cover 11 to the greatest extent, thereby ensuring the shooting quality of the camera 22.
