Description

Technical Field

[0001] This invention relates to the field of construction, specifically to a BIM-based remote building monitoring system. Background Technology

[0002] Currently available remote monitoring technologies mostly use cameras or motion recognition systems as tools to monitor the status of buildings. Although intuitive, the information obtained is limited to surface dynamic changes and cannot obtain more accurate physical data.

[0003] In the construction field, there are already examples of using BIM technology to assist in monitoring, and this technology is constantly being improved and refined. Combining BIM with engineering construction monitoring is indeed feasible. BIM technology (Building Information Modeling) is a specific application of digital technology in construction engineering, enabling designers to proactively respond to various building information for collaborative work. Utilizing the obtained real-time monitoring information, corresponding building models can be constructed, transforming abstract monitoring data into vivid simulated images. Existing technologies include various remote monitoring devices that combine BIM technology. For example, patent document CN212484367U discloses a remote monitoring device for engineering construction based on BIM and VR. This device combines BIM and VR technologies, first using the obtained real-time monitoring information to construct a corresponding building model, and then using VR technology to visualize the BIM building model built using remotely monitored engineering construction information. The VR system vividly presents the information to staff, allowing them to intuitively experience the specific scene of the building site while obtaining accurate monitoring information. Furthermore, VR's multi-view technology enables staff to easily observe blind spots or hidden areas of the actual building, thus achieving better monitoring results. However, to implement the above technology, the use of video capture cameras and various environmental sensors is still indispensable. Due to the limitations of the building environment, the surface of existing remote acquisition components is easily dusted and damaged, which reduces the acquisition accuracy and increases the maintenance frequency and difficulty. Therefore, this invention provides a BIM-based remote building monitoring system to solve the problems mentioned in the background. Summary of the Invention

[0004] This invention addresses the technical problems existing in the prior art by providing a BIM-based remote building monitoring system. This system solves the problem that, due to the limitations of the building environment, the surface of the remote acquisition components in the prior art is easily covered with dust and dirt, which reduces the acquisition accuracy of the acquisition device and increases the maintenance frequency and difficulty.

[0005] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A BIM-based building remote monitoring system includes a column, a core rod fixedly installed at the axial position of the column, a rotary cylinder driven by a first motor rotatably connected to the circumferential side of the core rod, a transmission solenoid driven by a second motor rotatably connected to the circumferential side of the rotary cylinder, a drive ring drivingly connected to the circumferential side of the transmission solenoid, a guide frame slidably connected to the drive ring fixed at the top of the rotary cylinder, a driven ring rotatably connected to the circumferential side of the column, a set of environmental monitoring modules arranged in a circular array installed between the opposite surfaces of the driven ring and the drive ring, a lower gear ring drivingly connected to the environmental monitoring modules fixedly installed on the circumferential side of the column, a set of monitoring mechanisms arranged in a circular array fixedly installed on the circumferential side of the rotary cylinder, a top plate fixedly installed at the top of the core rod, an upper gear ring drivingly connected to the monitoring mechanisms fixedly installed on the circumferential side of the top plate, and a blower and a liquid storage module communicating with the monitoring mechanisms respectively installed on the bottom surface of the top plate.

[0006] The beneficial effects of this invention are:

[0007] 1) By setting up monitoring mechanisms and environmental monitoring modules, this remote monitoring device can efficiently complete remote monitoring of buildings in conjunction with BIM technology. In addition, this device adds self-cleaning and dustproof structures to the monitoring elements. The addition of these self-cleaning and dustproof structures effectively reduces the maintenance difficulty and frequency of this detection device. Furthermore, the addition of these self-maintenance functions can effectively improve the accuracy of data acquisition during the acquisition operation and the working stability of the acquisition elements.

[0008] 2) In this invention, when the environmental monitoring module performs environmental monitoring, the rotary cylinder drives the environmental monitoring module to rotate periodically. When the environmental monitoring module rotates, due to the meshing connection between the lower gear ring and the lower gear, the lower gear drives the linkage shaft b to rotate. After the linkage shaft b rotates, it then drives the spin shaft to rotate through the transmission sleeve and the linkage shaft a. After the spin shaft rotates, it then drives the environmental monitoring sensor on the spin shaft to perform synchronous revolution and rotation. Through the synchronous rotation and revolution of the environmental sensor, on the one hand, the monitoring positions of multiple environmental sensors can be switched cyclically, thereby improving the environmental monitoring and environmental monitoring range of the environmental sensor. On the other hand, through the rotation state of the environmental sensor, the dust accumulation rate on the surface of the environmental sensor and the self-dust removal effect can be effectively reduced. Through the realization of the above effects, the maintenance difficulty of the environmental sensor is effectively reduced and the monitoring accuracy of the environmental sensor is maintained.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the environmental monitoring module includes a hinge base fixedly connected to a driven rotating ring. A monitoring arm is hinged to the inner wall of the hinge base via a hinge shaft. A connecting rod is hinged between the monitoring arm and the opposite surface of the drive ring. A spin shaft is rotatably connected to the inner wall of the monitoring arm. An environmental sensor is fixedly installed at the top of the spin shaft. The environmental sensors in each environmental monitoring module have different functions. A linkage shaft a is rotatably connected to the side of the monitoring arm. A transmission sleeve is rotatably connected to the circumferential side of the hinge shaft. The circumferential side of the transmission sleeve is connected to the linkage shaft a via a chain. A linkage shaft b is rotatably connected to the inner wall of the hinge base. A lower gear connected to the lower gear ring is fixedly installed at the bottom of the linkage shaft b. A transmission bevel gear b is fixedly installed at the top of the linkage shaft b. A driven bevel gear b meshing with the transmission bevel gear b is fixedly installed on the circumferential side of the transmission sleeve. A transmission bevel gear s is fixedly installed on the circumferential side of the linkage shaft a. A driven bevel gear s meshing with the transmission bevel gear b is fixedly installed on the circumferential side of the spin shaft.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, in the non-use state, under the action of the transmission solenoid, the driving ring and the driven ring are fully separated, thereby realizing the automatic retraction and storage of the monitoring arm. When it is necessary to monitor relevant environmental data in the monitoring environment, the driving ring is displaced to a set degree by controlling the transmission solenoid, thereby unfolding the monitoring arm. After the monitoring arm is unfolded at a set angle, the environmental sensor can monitor the environmental data in the building environment. During deployment, the environmental sensors installed on the environmental monitoring module can be set as temperature and humidity sensors, noise sensors, air quality sensors, and rainfall sensors, respectively. The temperature and humidity sensors, noise sensors, air quality sensors, and rainfall sensors can all be customized or selected according to actual needs.

[0012] Furthermore, when the environmental monitoring module performs environmental monitoring, the rotary cylinder drives the environmental monitoring module to rotate periodically. During the rotation of the environmental monitoring module, due to the meshing connection between the lower gear ring and the lower gear, the lower gear drives the linkage shaft b to rotate. After the linkage shaft b rotates, it then drives the spin shaft to rotate through the transmission sleeve and the linkage shaft a. After the spin shaft rotates, it then drives the environmental monitoring sensor on the spin shaft to perform synchronous revolution and rotation. Through the synchronous rotation and revolution of the environmental sensor, on the one hand, the monitoring positions of multiple environmental sensors can be switched cyclically, thereby improving the environmental monitoring and monitoring range of the environmental sensor. On the other hand, the rotation of the environmental sensor can effectively reduce the dust accumulation rate on the surface of the environmental sensor and improve the self-dust removal effect. Through the realization of the above effects, the maintenance difficulty of the environmental sensor is effectively reduced and the monitoring accuracy of the environmental sensor is maintained.

[0013] Furthermore, a linkage bevel gear ring is fixedly installed at the bottom of both the indexing cylinder and the transmission solenoid, and an actuating bevel gear that meshes with the linkage bevel gear ring is fixedly installed at the output shaft ends of both the first motor and the second motor.

[0014] Furthermore, the monitoring mechanism includes a connecting frame, the surface of which is fixedly connected to a rotary cylinder. A vertically arranged screw lifting module is fixedly installed on the inner wall of the connecting frame. A monitoring shell, which is slidably connected to the screw lifting module, is driven by the connecting frame. The surface of the monitoring shell is provided with a semi-circular baffle and a semi-circular light-transmitting part. An electrically adjustable camera body is installed on the inner wall of the monitoring shell. A transparent cover is rotatably connected to the inner wall of the monitoring shell at a position corresponding to the outer side of the camera body. The transparent cover is driven by an upper gear ring. A water purification component is installed on the inner wall of the monitoring shell at a position corresponding to the lower part of the transparent cover. A set of heating rods is installed on the inner wall of the monitoring shell at a position corresponding to the outer side of the transparent cover. A brush roller that rotates and fits against the transparent cover is rotatably connected to the inner wall of the transparent cover. A heating wire is built into the inside of the brush roller. An air purification component that cooperates with the transparent cover is installed on the surface of the monitoring shell.

[0015] The beneficial effects of adopting the above-mentioned further solution are that the screw lifting module includes a drive motor and a vertically arranged lifting screw. The output shaft end of the drive motor is fixedly connected to the lifting screw. The function of the screw lifting module is to adjust the installation height of the monitoring shell. By independently adjusting the installation height of multiple monitoring units, staggered monitoring can be achieved during video surveillance. The water cleaning component is used to clean the surface of the transparent cover. The heating rod is used to perform heat drying on the cleaned transparent cover. The brush roller is used to perform secondary cleaning on the dried transparent cover. Both the heating rod and the heating wire are equipped with a temperature control circuit and a temperature control resistor during operation. Through the setting of the temperature control circuit and the temperature control resistor, the heating rod and the heating wire can be kept in a constant temperature heating state during operation.

[0016] Furthermore, the inner wall of the monitoring housing is rotatably connected to a vertically arranged drive shaft. An upper toothed roller that is connected to the upper gear ring is fixedly installed at the top of the drive shaft. A linkage bevel gear is fixedly installed at the bottom of the drive shaft. A linkage bevel gear ring that meshes with the linkage bevel gear is fixedly installed on the peripheral side of the transparent cover. The thickness of the upper toothed roller is 15 to 35 times the thickness of the upper gear ring.

[0017] The beneficial effect of adopting the above-mentioned further solution is that when the indexing drum rotates, due to the meshing connection structure of the upper toothed ring and the upper toothed roller, the driving shaft drives the transparent cover to rotate. After the transparent cover rotates, it can be used evenly and receive water cleaning and hot drying operations evenly. By setting the thickness difference between the upper toothed roller and the upper toothed ring, it is ensured that the upper toothed ring can effectively transmit power to the upper toothed roller during the process of height change of the monitoring shell.

[0018] Furthermore, the water purification component includes a transmission gear ring fixed to the periphery of the transparent cover, a water distribution pipe, and two symmetrically arranged water purification shaft tubes. The surface of the water distribution pipe is fixedly connected to the monitoring shell, and the periphery of both water purification shaft tubes is rotatably connected to the monitoring shell. The tail end of each water purification shaft tube is rotatably connected to the water distribution pipe. The interior of each water purification shaft tube has several sets of water spray holes arranged in a circular array. A forward spiral brush and a reverse spiral brush are fixedly installed on the periphery of each of the two water purification shaft tubes. The periphery of both the forward and reverse spiral brushes is rotatably fitted to the transparent cover. A passive gear connected to the transmission gear ring is fixedly installed on the periphery of each water purification shaft tube. One end of the water inlet of the water distribution pipe is fixedly connected to the liquid storage module through a corrugated water inlet hose. Several dirt outlet holes are opened on the bottom surface of the semi-arc baffle, corresponding to the positions below the forward and reverse spiral brushes.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, in use, both the forward spiral brush and the reverse spiral brush include an inner spiral skeleton, the edge of which is wrapped with soft bristles. The function of the forward spiral brush and the reverse spiral brush is to perform bidirectional physical cleaning of the surface of the transparent cover. During the cleaning operation, the water spray hole sprays water at a set pressure, thereby achieving water cleaning of the surface of the transparent cover.

[0020] Furthermore, the air purification component includes an air inlet pipe fixed to the side of the monitoring housing. One end of the air inlet of the air inlet pipe is fixedly connected to the blower through a corrugated air inlet pipe. The interior of the air inlet pipe is provided with several sets of dust suppression spray holes arranged in a circumferential array. The axis of the dust suppression spray holes is parallel to the axis of the transparent cover, and the dust suppression spray holes are located on the outside of the transparent cover.

[0021] The beneficial effect of adopting the above-mentioned further solution is that when the camera body is working, the blower maintains normal high-pressure air output in the set state. After the blower outputs high-pressure air, the adhesion rate of dust on the surface of the transparent cover is reduced. A filter element for air filtration is fixedly installed at one end of the air inlet of the blower. The function of the filter element is to filter impurities in the air.

[0022] Furthermore, the transparent cover is made of transparent PVC material, the heating rod is placed between the water cleaning component and the brush roller, and an electrical control box is fixedly installed on the periphery of the column. The electrical control box contains a central control host and a remote data communication module, and the central control host has a built-in BIM design module.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the remote communication module enables the central control host to receive control from the remote central control device in real time and to transmit the monitoring data of the central control host to the external remote central control device in real time. The BIM design module includes a BIM database. Under the coordination of the central control host, the BIM design module combines the collected and processed information on the engineering building to construct a three-dimensional data model of the building at the corresponding stage and stores it in the BIM database for the central control host to retrieve. The central control host converts the three-dimensional data model of the BIM database into a three-dimensional model for VR devices and displays it on the VR devices.

[0024] Furthermore, the liquid storage module includes a liquid storage tank fixedly connected to the top plate, a pump body is installed on the surface of the liquid storage tank, one end of the pump body's liquid inlet is fixedly connected to the liquid storage tank, one end of the pump body's liquid outlet is fixedly connected to the corrugated water inlet hose, and a replenishment pipe is fixedly installed on the top surface of the liquid storage tank.

[0036] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0037] The present invention provides the following preferred embodiments.

[0038] like Figure 1-9 As shown, a BIM-based building remote monitoring system includes a column 1, a core rod 2 fixedly installed on the axial position of the column 1, a rotating cylinder 4 driven by a first motor 3 rotatably connected to the circumferential side of the core rod 2, and a transmission solenoid 6 driven by a second motor 5 rotatably connected to the circumferential side of the rotating cylinder 4. The surfaces of the first motor 3 and the second motor 5 are both fixedly connected to the column 1.

[0039] Both the bottom of the indexing cylinder 4 and the transmission solenoid 6 are fixedly installed with a linkage bevel gear ring, and the output shaft ends of the first motor 3 and the second motor 5 are fixedly installed with an actuating bevel gear that meshes with the linkage bevel gear ring.

[0040] The drive ring 7 is connected to the circumferential side of the drive solenoid 6. The top of the indexing cylinder 4 is fixed with a guide frame 8 that is slidably connected to the drive ring 7. The driven ring 9 is rotatably connected to the circumferential side of the column 1. A set of environmental monitoring modules arranged in a circular array is installed between the opposite surfaces of the driven ring 9 and the drive ring 7. The lower gear ring 10 that is connected to the environmental monitoring modules is fixedly installed on the circumferential side of the column 1.

[0041] The environmental monitoring module includes a hinge base 15 fixedly connected to the driven rotating ring 9. A monitoring arm 16 is hinged to the inner wall of the hinge base 15 via a hinge shaft. A connecting rod 17 is hinged between the monitoring arm 16 and the opposing surface of the drive ring 7. A spin shaft 18 is rotatably connected to the inner wall of the monitoring arm 16. An environmental sensor 19 is fixedly mounted at the top of the spin shaft 18. The function of the environmental sensor 19 differs in each environmental monitoring module. A linkage shaft a20 is rotatably connected to the side of the monitoring arm 16. A transmission sleeve 21 is rotatably connected to the circumferential side of the hinge shaft. The peripheral side of 1 is connected to the linkage shaft a20 via a chain. The inner wall of the hinge 15 is rotatably connected to the linkage shaft b22. The bottom end of the linkage shaft b22 is fixedly installed with a lower gear that is connected to the lower gear ring 10. The top end of the linkage shaft b22 is fixedly installed with a transmission bevel gear b. The peripheral side of the transmission sleeve 21 is fixedly installed with a driven bevel gear b that meshes with the transmission bevel gear b. The peripheral side of the linkage shaft a20 is fixedly installed with a transmission bevel gear s. The peripheral side of the spin shaft 18 is fixedly installed with a driven bevel gear s that meshes with the transmission bevel gear b.

[0042] In non-use state, under the action of the transmission solenoid 6, the drive ring 7 and the driven ring are fully separated, thereby realizing the automatic retraction and storage of the monitoring arm 16. When it is necessary to monitor relevant environmental data in the monitoring environment, the drive ring 7 is displaced to a set degree by controlling the transmission solenoid 6, thereby causing the monitoring arm 16 to unfold. After the monitoring arm 16 unfolds at a set angle, the environmental sensor 19 monitors the environmental data in the building environment. During deployment, the environmental sensor 19 installed on the environmental monitoring module can be set as a temperature and humidity sensor, a noise sensor, an air quality sensor, and a rainfall sensor. The temperature and humidity sensor, noise sensor, air quality sensor, and rainfall sensor can all be customized or selected according to actual needs.

[0043] Furthermore, when the environmental monitoring module performs environmental monitoring, the rotary cylinder 4 drives the environmental monitoring module to rotate periodically. When the environmental monitoring module rotates, due to the meshing connection between the lower gear ring 10 and the lower gear, the lower gear drives the linkage shaft b22 to rotate. After the linkage shaft b22 rotates, it then drives the spin shaft 18 to rotate through the transmission sleeve 21 and the linkage shaft a20. After the spin shaft 18 rotates, it then drives the environmental monitoring sensor on the spin shaft 18 to perform synchronous revolution and rotation. Through the synchronous rotation and revolution of the environmental sensor 19, on the one hand, the monitoring positions of multiple environmental sensors 19 can be switched cyclically, thereby improving the environmental monitoring and environmental monitoring range of the environmental sensor 19. On the other hand, through the rotation state of the environmental sensor 19, the dust accumulation rate on the surface of the environmental sensor 19 can be effectively reduced and the self-dust removal effect can be improved. Through the realization of the above effects, the maintenance difficulty of the environmental sensor 19 is effectively reduced and the monitoring accuracy of the environmental sensor 19 is maintained.

[0044] A set of monitoring mechanisms arranged in a circular array are fixedly installed on the circumferential side of the indexing cylinder 4. A top plate 11 is fixedly installed at the top of the core rod 2. An upper gear ring 12 that is connected to the monitoring mechanism is fixedly installed on the circumferential side of the top plate 11. A blower 13 and a liquid storage module 14 that are connected to the monitoring mechanism are respectively installed on the bottom surface of the top plate 11.

[0045] When the environmental monitoring module performs environmental monitoring, the rotary cylinder 4 drives the environmental monitoring module to rotate periodically. During the rotation of the environmental monitoring module, due to the meshing connection between the lower gear ring 10 and the lower gear, the lower gear drives the linkage shaft b22 to rotate. After the linkage shaft b22 rotates, it then drives the spin shaft 18 to rotate through the transmission sleeve 21 and the linkage shaft a20. After the spin shaft 18 rotates, it drives the environmental monitoring sensor on the spin shaft 18 to perform synchronous revolution and rotation. Through the synchronous rotation and revolution of the environmental sensor 19, on the one hand, the monitoring positions of multiple environmental sensors 19 can be switched cyclically, thereby improving the environmental monitoring and environmental monitoring range of the environmental sensor 19. On the other hand, the rotation of the environmental sensor 19 can effectively reduce the dust accumulation rate on the surface of the environmental sensor 19 and improve the self-dust removal effect. Through the above effects, the maintenance difficulty of the environmental sensor 19 is effectively reduced and the monitoring accuracy of the environmental sensor 19 is maintained.

[0046] The monitoring mechanism includes a connecting frame 23, the surface of which is fixedly connected to the rotary cylinder 4. A vertically arranged screw lifting module 24 is fixedly installed on the inner wall of the connecting frame 23. A monitoring housing 25, which is slidably connected to the inner wall of the connecting frame 23 and is drivenly connected to the screw lifting module 24, is also connected to the inner wall of the connecting frame 23. The surface of the monitoring housing 25 is provided with a semi-circular baffle and a semi-circular light-transmitting part. An electrically adjustable camera body 26 is installed on the inner wall of the monitoring housing 25. The inner wall of the monitoring housing 25 corresponds to the outer side of the camera body 26. A transparent cover 27 is rotatably connected to the monitoring housing 25. The transparent cover 27 is driven by the upper gear ring 12. A water purification component is installed on the inner wall of the monitoring housing 25 and at the position corresponding to the lower part of the transparent cover 27. A set of electric heating rods 28 is installed on the inner wall of the monitoring housing 25 and at the position corresponding to the outer side of the transparent cover 27. A brush roller 29 that rotates and fits with the transparent cover 27 is rotatably connected to the inner wall of the transparent cover 27. The brush roller 29 has an electric heating wire built into its interior. An air purification component that cooperates with the transparent cover 27 is installed on the surface of the monitoring housing 25.

[0047] The lead screw lifting module 24 includes a drive motor and a vertically arranged lifting lead screw. The output shaft of the drive motor is fixedly connected to the lifting lead screw. The function of the lead screw lifting module 24 is to adjust the installation height of the monitoring housing 25. The installation height of multiple monitoring units can be independently adjusted, thereby realizing staggered monitoring during video surveillance. The water cleaning component is used to clean the surface of the transparent cover 27. The heating rod 28 is used to perform heat drying on the cleaned transparent cover 27. The brush roller 29 is used to perform secondary cleaning on the dried transparent cover 27. Both the heating rod 28 and the heating wire are equipped with a temperature control circuit and a temperature control resistor during operation. Through the setting of the temperature control circuit and the temperature control resistor, the heating rod 28 and the heating wire can maintain a constant temperature heating state during operation.

[0048] The inner wall of the monitoring housing 25 is rotatably connected to a vertically arranged drive shaft 30. The top end of the drive shaft 30 is fixedly installed with an upper toothed roller 31 that is connected to the upper toothed ring 12 for transmission. The bottom end of the drive shaft 30 is fixedly installed with a linkage bevel gear. The circumferential side of the transparent cover 27 is fixedly installed with a linkage bevel gear ring that meshes with the linkage bevel gear. The thickness of the upper toothed roller 31 is 20 times the thickness of the upper toothed ring 12.

[0049] When the indexing drum 4 rotates, the meshing connection between the upper gear ring 12 and the upper gear roller 31 drives the rotating shaft 30 to rotate the transparent cover 27. After the transparent cover 27 rotates, it is used evenly and receives water cleaning and hot drying operations evenly. Through the thickness difference between the upper gear roller 31 and the upper gear ring 12, it is ensured that the upper gear ring 12 can effectively drive the upper gear roller 31 during the height change of the monitoring shell 25.

[0050] The water purification assembly includes a transmission gear ring 32 fixed to the periphery of the transparent cover 27, a water distribution pipe 33, and two symmetrically arranged water purification shaft tubes 34. The surface of the water distribution pipe 33 is fixedly connected to the monitoring shell 25. The periphery of the two water purification shaft tubes 34 is rotatably connected to the monitoring shell 25. The tail end of the water purification shaft tube 34 is rotatably connected to the water distribution pipe 33. The interior of the water purification shaft tube 34 has several sets of water spray holes arranged in a circular array. The periphery of the two water purification shaft tubes 34 is fixedly mounted with a forward spiral brush 35 and a reverse spiral brush 36, respectively. The periphery of the forward spiral brush 35 and the reverse spiral brush 36 are rotatably fitted to the transparent cover 27. The periphery of the water purification shaft tube 34 is fixedly mounted with a passive gear that is connected to the transmission gear ring 32. One end of the water inlet of the water distribution pipe 33 is fixedly connected to the liquid storage module 14 through a corrugated water inlet hose. The bottom surface of the semi-circular baffle and the position corresponding to the position below the forward spiral brush 35 and the reverse spiral brush 36 are provided with several dirt outlet holes.

[0051] In use, both the forward spiral brush 35 and the reverse spiral brush 36 include an inner spiral skeleton, the edges of which are wrapped with soft bristles. The purpose of the forward spiral brush 35 and the reverse spiral brush 36 is to perform bidirectional physical cleaning on the surface of the transparent cover 27. During the cleaning operation, the water spray hole sprays water at a set pressure, thereby achieving water cleaning on the surface of the transparent cover 27.

[0052] The air purification component includes an air inlet pipe 38 fixed to the side of the monitoring housing 25. One end of the air inlet of the air inlet pipe 38 is fixedly connected to the blower 13 through a corrugated connecting pipe. The interior of the air inlet pipe 38 is provided with several sets of dust suppression spray holes 39 arranged in a circumferential array. The axis of the dust suppression spray holes 39 is parallel to the axis of the transparent cover 27, and the dust suppression spray holes 39 are located on the outside of the transparent cover 27.

[0053] When the camera body 26 is working, the blower 13 maintains normal high-pressure air output in the set state. After the blower 13 outputs high-pressure air, the adhesion rate of dust on the surface of the transparent cover 27 is reduced. One end of the air inlet of the blower 13 is fixedly installed with an air filter element. The function of the filter element is to filter impurities in the air.

[0054] The transparent cover 27 is made of transparent PVC material. The heating rod 28 is placed between the water cleaning component and the brush roller 29. The power control box 37 is fixedly installed on the periphery of the column 1. The power control box 37 contains a central control host and a remote data communication module. The central control host has a built-in BIM design module.

[0055] The remote communication module enables the central control host to receive control data from remote central control devices in real time and to transmit monitoring data from the central control host to external remote central control devices in real time. The BIM design module includes a BIM database. Under the control of the central control host, the BIM design module combines the collected and processed information on the engineering building to construct a 3D data model of the building at the corresponding stage and stores it in the BIM database for the central control host to retrieve. The central control host then converts the 3D data model from the BIM database into a 3D model for VR devices and displays it on the VR devices.

[0056] The liquid storage module 14 includes a liquid storage tank fixedly connected to the top plate 11. A pump body is installed on the surface of the liquid storage tank. One end of the pump body's liquid inlet is fixedly connected to the liquid storage tank, and one end of the pump body's liquid outlet is fixedly connected to the corrugated water inlet hose. A replenishment pipe is fixedly installed on the top surface of the liquid storage tank.
