Description

Technical Field

[0001] The present invention relates to the technical field of engineering safety, and particularly to a multi-dimensional safety monitoring and warning device for a construction site construction area. Background Art

[0002] The use of a safety monitoring and warning device in a construction site construction area is to monitor various safety indicators in real time, timely discover potential safety hazards, and the warning device can immediately issue an alarm when an abnormal situation or data exceeds the safety range, thereby helping construction workers take measures to avoid accidents, improving the overall safety, and at the same time meeting the requirements of laws and regulations on construction safety in many regions. And by recording and analyzing data, it helps to evaluate and improve construction methods afterwards.

[0003] In the prior art, a Chinese patent document with the publication number CN117890925A, an aerial safety monitoring and warning device for substation construction, proposes that through the cooperation between a reciprocating swing motor, a lidar sensor, a warning light, and a buzzer, it can detect and scan the air at the operation boundary position. When an object enters the detection range in the air, it can issue a prompt in time to avoid the construction equipment from crossing the boundary and improve the safety of substation construction. However, consistent with the traditional method, traditional devices usually lack a dynamic adjustment function, and it is difficult to adjust the horizontal and vertical angles of the monitoring view. This fixed view makes the device unable to flexibly monitor according to different construction conditions or changing site environments. When the layout of the construction area changes or new construction tasks appear, the device with a fixed view may not be able to effectively cover the new area or adjust the monitoring strategy, thus affecting the comprehensiveness and accuracy of the monitoring. And since cameras and sensors are usually exposed to the external environment, they are easily affected by factors such as dust, dirt, and rain, resulting in the field of view being blocked or sensor readings being inaccurate. Manual cleaning is not only time-consuming and laborious, but also may not be able to completely remove all dirt or dust. In addition, frequent manual maintenance may increase the downtime of the equipment and affect the effectiveness and real-time nature of continuous monitoring. Therefore, this application discloses a multi-dimensional safety monitoring and warning device for a construction site construction area to meet the dynamic adjustment and cleaning capabilities during monitoring. Summary of the Invention

[0017] The beneficial effects of the present invention:

[0018] 1.

At the same time, the flipping component, through the precise control of the stepping motor, further realizes the flexible adjustment of the monitoring chamber in the horizontal and vertical angles to meet the requirements of different working conditions and ensure the dynamic adaptability of the monitoring perspective. The design of the damper and the buffer plate effectively reduces the vibration and impact during the rotation of the equipment, ensuring the stability and service life of the monitoring equipment.

This component uses an arc-shaped top plate and a cleaning brush that matches the surface of the monitoring room, and can comprehensively clean the monitoring room when it rotates, maintaining a clear view of the camera and sensors. During the cleaning process, the telescopic rod provides elastic buffering to ensure smooth contact and avoid damaging the equipment. In addition, the scraper works in coordination with the cleaning brush, and the rotation of the monitoring room triggers the scraper to automatically remove the residues on the brush, ensuring that the cleaning brush is in the best state every time it cleans. The design of the reset spring ensures that the scraper automatically resets after the cleaning is completed, avoiding manual intervention and improving the automation level of the system.

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with specific embodiments.

[0034] Such as Figures 1 to 9As shown in the figure, a multi-dimensional safety monitoring and warning device for a construction site includes a bottom plate 1. An installation plate 12 is movably installed at the top of the bottom plate 1, and a rotating disc 15 is rotatably installed above the installation plate 12; an adjustment component, which includes a lifting module and a rotating module. The lifting module is arranged between the bottom plate 1 and the installation plate 12, and the lifting module is used to lift the installation plate 12. The rotating module is arranged above the installation plate 12, and a flipping component is fixedly installed above the rotating module. A monitoring room 43 is fixedly and rotatably installed on the flipping component. A camera is arranged inside the monitoring room 43. The rotating module is used to drive the flipping component and the monitoring room 43 to rotate. The flipping component is used to adjust the monitoring angle of the monitoring room 43. A cleaning component is also arranged above the flipping component, and the cleaning component is used to clean the monitoring room 43; a control system, which includes a sensor module, a wearable module, a communication module, a central processing unit, and a warning module. The sensor module is respectively integrated inside the monitoring room 43 and the wearable module, and data transmission is carried out between the sensors through the communication module. The sensor module is used to collect multi-dimensional data in the construction site construction environment in real time. The wearable module is composed of several independent sub-individuals, and the wearable module is respectively worn or carried on the workers. The wearable module is used for the safety monitoring of construction site workers and can provide personal safety warnings for workers through lightweight sensors and feedback mechanisms. The central processing unit is arranged inside the monitoring room 43, and the central processing unit is used to receive the data collected by the sensor module and the wearable module, and process and analyze them according to preset algorithms and rules. The warning module is arranged inside the wearable module, and the warning module is used to notify on-site workers and remote managers of the safety status and issue an emergency alarm when necessary. Among them, the sensor module includes a lidar sensor and a radar sensor arranged inside the monitoring room 43, and a GPS module arranged inside the wearable module. The lidar sensor is used to scan the three-dimensional environment around the construction site to detect obstacles and moving objects. The radar sensor is used to monitor the speed and position of personnel or mechanical equipment. The GPS module is used to locate the working range of workers;

[0035] After the device is started, the bottom plate 1 is fixed to the ground of the construction area. The lifting module adjusts the lifting of the mounting plate 12 under the control of the central processing unit to ensure that the cameras and sensors in the monitoring room 43 can cover the target area. Subsequently, the rotation module starts to work, driving the monitoring room 43 to rotate 360°. At the same time, the flipping assembly adjusts the monitoring angle of the monitoring room 43 according to requirements to ensure that the entire construction area is monitored without dead angles. The lidar sensor scans the three-dimensional environment around the construction site, and detects the distance and shape of obstacles and moving objects in real time. The radar sensor monitors the speed and position of personnel and mechanical equipment. The GPS module tracks the positions of workers to ensure that they are within a safe working range. The wearable module (such as a safety helmet or bracelet) worn on the workers continuously monitors the positions and states of the workers. When a worker approaches a dangerous area or an abnormality occurs, the sensors in the wearable module transmit real-time data to the central processing unit through the communication module. The central processing unit analyzes the data according to the preset safety algorithm. If a potential safety hazard is detected, the warning module is immediately triggered. The warning module immediately reminds the worker of the danger through sound, light or vibration feedback. At the same time, the system sends the alarm information to the remote monitoring center through the communication module for the management personnel to view and take further measures. When the cameras or sensors in the monitoring room 43 detect that external pollution affects their normal operation, the cleaning assembly is activated to clean the outside of the monitoring room 43 to ensure that the vision and detection capabilities of the monitoring equipment are always in the best state.

[0036] As Figures 1 to 5 shown, the lifting module includes support sleeves 2 fixedly installed at the four corners of the bottom plate 1. The support sleeves 2 are arranged in groups of two, and the two groups of support sleeves 2 are arranged oppositely. Semi-circular notches are formed on the opposite surfaces of the two groups of support sleeves 2. Positioning rings 3 are arranged on both the upper and lower sides of the support sleeve 2. A lifting column 4 is slidably installed inside the support sleeve 2, and the lifting column 4 penetrates through the positioning ring 3. Meshing teeth 5 are formed on the opposite surfaces of the lifting column 4. The top of the lifting column 4 is fixedly connected to the bottom of the mounting plate 12. Two groups of positioning plates 6 are arranged in the middle of the top surface of the bottom plate 1. Rotating rods 7 are rotatably installed on the two groups of positioning plates 6. Driven gears 8 are fixedly connected to both ends of the two rotating rods 7. The four driven gears 8 are respectively meshed with the meshing teeth 5 on the four lifting columns 4, and the driven gears 8 on both sides of the two rotating rods 7 are meshed with each other. A rotating motor 9 is also fixedly installed in the middle of the top surface of the bottom plate 1. A screw rod 10 is fixedly connected to the output end of the rotating motor 9. A driving gear 11 is fixedly sleeved on the middle of one of the rotating rods 7. The driving gear 11 is meshed with the screw rod 10;

[0037] When an instruction needs to be issued to start the lifting module after the information sent by the sensor module is processed by the central processing unit, the rotation motor 9 is first controlled to start. The output end of the rotation motor 9 drives the screw rod 10 to rotate. The screw rod 10 meshes with the driving gear 11. The driving gear 11 starts to rotate as the screw rod 10 rotates. Since the driving gear 11 is fixed in the middle of the rotating rod 7, the rotating rod 7 rotates synchronously with the movement of the driving gear 11, driving the driven gears 8 at both ends to rotate. The four driven gears 8 are respectively meshed with the meshing teeth 5 on the four lifting columns 4. When the driven gear 8 rotates, it drives the lifting column 4 with the meshing teeth 5 to slide up and down inside the support sleeve 2. Since the two groups of support sleeves 2 are arranged oppositely, and the driven gears 8 on both sides of the two rotating rods 7 mesh with each other, the four lifting columns 4 can achieve synchronous lifting and lowering under the linkage of gear transmission. The lifting column 4 passes through the positioning ring 3 in the support sleeve 2 up and down to ensure that it moves in a straight line during the lifting process and avoid swaying left and right. The top of the lifting column 4 is fixedly connected to the bottom of the mounting plate 12. Therefore, when the lifting columns 4 rise or fall synchronously, the mounting plate 12 also rises and falls smoothly, ensuring that the balance of the mounting plate 12 is not affected during the lifting process and effectively avoiding tilting or shaking;

[0038] The rotation module includes a positioning disk 13 fixedly installed on the mounting plate 12, and a rotating disk 15 rotatably installed on the positioning disk 13. A sliding groove 14 is formed on the outer surface of the positioning disk 13. A number of limit posts 16 are arranged in a circumferential array on the bottom outer circumference of the rotating disk 15. A number of limit wheels 17 are rotatably installed at the bottom of the number of limit posts 16. The number of limit wheels 17 are all rolling and clamped inside the sliding groove 14. A servo motor 19 is also fixedly installed between the positioning disk 13 and the rotating disk 15. The output end of the servo motor 19 is fixedly connected to a rotating gear 20. A linkage ring 18 is also fixedly installed in the middle of the bottom end of the rotating disk 15. A number of teeth meshing with the rotating gear 20 are arranged in a circumferential array on the bottom surface of the linkage ring 18;

[0039] When an instruction needs to be issued to start the rotation module after the information sent by the sensor module is processed by the central processing unit, first, the servo motor 19 starts to work. The output end of the servo motor 19 drives the rotation gear 20 to rotate. The rotation gear 20 meshes with the teeth at the bottom of the linkage ring 18 through its teeth, driving the linkage ring 18 to rotate. Since the linkage ring 18 is fixedly installed in the middle of the bottom end of the rotating disc 15, the rotation of the linkage ring 18 directly drives the rotating disc 15 to rotate synchronously. To ensure the stability of the rotating disc 15 during rotation, a number of limit posts 16 are evenly arranged along the outer periphery of the bottom of the rotating disc 15. A rotatable limit wheel 17 is installed at the bottom of the limit post 16, and the limit wheel 17 is rolling and clamped inside the sliding groove 14 of the positioning disc 13. As the rotating disc 15 rotates, the limit wheel 17 slides along the track of the sliding groove 14, ensuring that the rotating disc 15 does not deviate from the track during rotation, nor does it shake or tilt. Under the control of the servo motor 19, the rotating disc 15 can rotate at a predetermined angle and speed. Through the precise control of the servo motor 19, the system can adjust the rotation angle of the monitoring room 43 to ensure that the camera and sensor can monitor the construction area of the construction site in all directions and at multiple angles.

[0040] As Figure 1 , Figure 6 shown, the flipping assembly includes a connecting piece 21, a positioning piece 22, a mounting base 25, a first positioning seat 26, and a second positioning seat 27. The connecting piece 21 is fixedly installed on the top surface of the rotating disc 15. The positioning piece 22 is fixedly installed at the upper end of the connecting piece 21 through four support columns. Dampers 23 are respectively connected to the four corners of the positioning piece 22. The bottom sides of both sides of the positioning piece 22 are movably connected with buffer plates 24, and both sides of the two buffer plates 24 are connected to the bottom of the damper 23. The mounting base 25 is fixedly installed on the top surface of the buffer plate 24. A first positioning seat 26 is fixedly installed on the top surface of the mounting base 25. A second positioning seat 27 is rotatably installed on the top surface of the first positioning seat 26. The second positioning seat 27 is arranged in a U shape. A third positioning seat 30 is rotatably installed at one inner end of the second positioning seat 27. The monitoring room 43 is fixedly installed on the third positioning seat 30. A first stepping motor 28 is fixedly installed on one side of the first positioning seat 26. The output end of the first stepping motor 28 is rotatably installed with a first connecting rod 29. The other end of the first connecting rod 29 is rotatably connected to one side of the second positioning seat 27. A second stepping motor 31 is fixedly installed on one side of the second positioning seat 27. A connecting plate is sleeved on the output end of the second stepping motor 31. The other end of the connecting plate is rotatably connected to a second connecting rod 32. A triangular chuck 33 is rotatably installed at the bottom of one side of the third positioning seat 30. The other end of the second connecting rod 32 is rotatably connected to the bottom of the triangular chuck 33;

[0041] The first stepping motor 28 starts to work, driving the first connecting rod 29 at the output end to rotate. The other end of the first connecting rod 29 is connected to the side surface of the second positioning seat 27, causing the second positioning seat 27 to rotate and adjust around the axis of the first positioning seat 26. At this time, the monitoring chamber 43 starts to adjust its horizontal angle through the combined structure of the second positioning seat 27 and the third positioning seat 30. Then, the second stepping motor 31 starts to work, driving the triangular chuck 33 to rotate through the connecting plate and the second connecting rod 32 connected to its output end. The triangular chuck 33 is connected to the bottom of the third positioning seat 30, thereby driving the monitoring chamber 43 to adjust its vertical angle around its own axis. The entire rotation and flipping process are carried out under the precise control of the stepping motor, ensuring that the monitoring chamber 43 can quickly and stably monitor the construction area from multiple angles. At the same time, the positioning piece 22 is connected to the buffer plate 24 through the damper 23. During the process of the monitoring chamber 43 adjusting the angle, the damper 23 can effectively absorb the vibration and impact force generated during the rotation of the equipment, ensuring the stability of the monitoring screen and the service life of the equipment. During the operation of the entire flipping assembly, the coordinated cooperation of each component ensures that the monitoring chamber 43 can flexibly adapt to the complex requirements in the construction site environment without sacrificing stability, achieving precise and comprehensive safety monitoring.

[0042] As Figure 1 , Figure 7 , Figure 8 shown, the cleaning assembly includes fixing blocks 34 fixedly installed on both sides of the top surface of the second positioning seat 27. Both fixing blocks 34 are arranged in an inverted L shape. An upward-arching top plate 35 is fixedly installed between the two fixing blocks 34. The radian of the top plate 35 is adapted to the spherical radian of the monitoring chamber 43. A number of cleaning brushes 36 are arranged on the bottom surface of the top plate 35. On the side of the two fixing blocks 34 away from the monitoring chamber 43, a lower connecting block 40 is fixedly installed. On the side of the lower connecting block 40 close to the monitoring chamber 43, a number of telescopic rods 41 are fixedly installed. A return spring 42 is sleeved on the telescopic ends of the number of telescopic rods 41. One end of the top plate 35 close to the monitoring chamber 43 is movably installed with a scraper 37. The scraper 37 is used to scrape off the residues on the cleaning brushes 36. Both sides of the side of the scraper 37 away from the monitoring chamber 43 are fixedly connected to the telescopic ends of the number of telescopic rods 41. L-shaped extension plates 38 are fixedly installed on both sides of the scraper 37. A trigger rod 39 is fixedly installed between the two extension plates 38. The trigger rod 39 is arranged in an arc shape;

[0043] When the monitoring chamber 43 is vertically rotated to a certain angle by the second-step motor 31, its top will gradually approach the cleaning assembly. As the monitoring chamber 43 continues to rotate, the first thing it touches is the trigger rod 39. The trigger rod 39 is fixed between two extension plates 38. At this time, the trigger rod 39 is pushed by the monitoring chamber 43, driving the extension plates 38 and the scraper 37 to move to one side together, so that the scraper 37 starts to scrape the residues on the cleaning brush 36, ensuring that the cleaning brush 36 is in the best state. As the rotation of the monitoring chamber 43 continues, the outer surface of the monitoring chamber 43 will contact the cleaning brush 36 at the bottom of the top plate 35. Since the arc of the top plate 35 is adapted to the spherical arc of the monitoring chamber 43, the cleaning brush 36 can cover most areas of the surface of the monitoring chamber 43 for comprehensive cleaning. At the same time, the telescopic rod 41 on the fixed block 34 provides elastic buffering to ensure the smoothness of contact during the cleaning process. When the cleaning is completed and the monitoring chamber 43 rotates away from the cleaning assembly, the scraper 37 will be automatically reset to the initial position under the drive of the return spring 42.
