Description

Technical Field

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

[0002] The purpose of using safety monitoring and early warning devices in construction areas of construction sites is to monitor various safety indicators in real time and promptly identify potential safety hazards. The early warning devices can immediately sound an alarm when abnormal conditions are detected or data exceeds the safe range, thereby helping construction personnel take measures to avoid accidents and improve overall safety. At the same time, it also meets the requirements of many regional laws and regulations on construction safety, 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 publication number CN117890925A proposes an aerial safety monitoring and early warning device for substation construction, which proposes that through the cooperation between a reciprocating swing motor, a laser radar sensor, a warning light and a buzzer, it can detect and scan the air at the boundary of the operation. When an object in the air enters the detection range, a prompt can be issued in time to prevent the construction equipment from crossing the boundary and improve the safety of substation construction. However, consistent with the traditional method, the traditional device usually lacks a dynamic adjustment function, and the horizontal and vertical angles of the monitoring view are difficult to adjust. This fixed view makes it impossible for the device to flexibly monitor according to different construction conditions or changing on-site environments. When the construction area When the layout changes or new construction tasks arise, devices with fixed viewing angles may not be able to effectively cover new areas or adjust monitoring strategies, thus affecting the comprehensiveness and accuracy of monitoring. In addition, 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 blocked fields of view or inaccurate sensor readings. Manual cleaning is not only time-consuming and labor-intensive, but may not be able to completely remove all dirt or dust. In addition, frequent manual maintenance may lead to increased downtime of equipment, affecting the effectiveness and real-time nature of continuous monitoring. Therefore, the present application discloses a multi-dimensional safety monitoring and early warning device for construction areas of construction sites to meet the dynamic adjustment and cleaning capabilities during monitoring.

The lifting module adjusts the lifting of the mounting plate 12 through the control of the central processing unit to ensure that the camera and sensor of the monitoring room 43 can cover the target area. Then, the rotation module starts to work, driving the monitoring room 43 to rotate 360 ​​degrees. At the same time, the flip component adjusts the monitoring angle of the monitoring room 43 according to the needs to ensure that the entire construction area is monitored without blind spots. The laser radar 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 position of workers to ensure that they are within a safe working range.

[0023] like Figures 1 to 5 As 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 a group of two, the two groups of support sleeves 2 are arranged opposite to each other, and the opposite surfaces of the two groups of support sleeves 2 are provided with semicircular notches, the upper and lower sides of the support sleeves 2 are provided with positioning rings 3, the interior of the support sleeves 2 is slidably installed with lifting columns 4, and the lifting columns 4 are arranged through the positioning rings 3, and the opposite surfaces of the positioning rings 3 are provided with meshing teeth 5, the top of the lifting columns 4 is fixedly connected to the bottom of the mounting plate 12, and the top surface of the bottom plate 1 Two groups of positioning plates 6 are arranged in the middle, and rotating rods 7 are rotatably installed on the two groups of positioning plates 6. Both ends of the two rotating rods 7 are fixedly connected with driven gears 8. 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, and a spiral rod 10 is fixedly connected to the output end of the rotating motor 9. A driving gear 11 is fixedly sleeved in the middle of one of the rotating rods 7 to mesh with the spiral rod 10; When the central processing unit issues an instruction to start the operation of the lifting module after processing the information sent by the sensor module, the rotating motor 9 is first controlled to start, and the output end of the rotating motor 9 drives the screw rod 10 to rotate, and the screw rod 10 meshes with the driving gear 11. The driving gear 11 starts to rotate with the rotation of the screw rod 10. Since the driving gear 11 is fixed to 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 gears 8 rotate, the meshing teeth 5 are driven to rise. The lowering column 4 slides up and down inside the supporting sleeve 2. Since the two groups of supporting sleeves 2 are arranged opposite to each other and the driven gears 8 on both sides of the two rotating rods 7 are meshed with each other, the four lifting columns 4 can be lifted and lowered synchronously under the linkage of the gear transmission. The lifting column 4 passes through the positioning ring 3 in the supporting sleeve 2 up and down to ensure that it maintains linear motion during the lifting process to 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 column 4 rises or falls 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, effectively avoiding tilting or shaking. The rotating module includes a positioning disc 13 fixedly mounted on a mounting plate 12, and a rotating disc 15 rotatably mounted on the positioning disc 13. A sliding groove 14 is provided on the outer surface of the positioning disc 13. A plurality of limiting columns 16 are arranged circumferentially on the outer circumference of the bottom of the rotating disc 15. A plurality of limiting wheels 17 are rotatably mounted on the bottoms of the limiting columns 16. The plurality of limiting wheels 17 are slidably engaged in the sliding groove 14. A servo motor 19 is also fixedly mounted between the positioning disc 13 and the rotating disc 15. A rotating gear 20 is fixedly connected to the output end of the servo motor 19. A linkage ring 18 is also fixedly mounted on the middle part of the bottom end of the rotating disc 15. A plurality of teeth meshing with the rotating gear 20 are arranged circumferentially on the bottom surface of the linkage ring 18. When the information sent by the sensor module is processed by the central processing unit and an instruction is issued to start the rotating module, the servo motor 19 starts working first, and the output end of the servo motor 19 drives the rotating gear 20 to rotate. The rotating gear 20 engages 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 at the middle of the bottom end of the rotating disk 15, the rotation of the linkage ring 18 directly drives the rotating disk 15 to rotate synchronously. In order to ensure that the rotating disk 15 remains stable during the rotation process, a number of limit posts 16 are evenly arranged along the bottom periphery of the rotating disk 15. The limiting wheel 17 is arranged at the bottom of the limiting column 16, and the limiting wheel 17 is slidably engaged in the sliding groove 14 of the positioning disc 13. As the rotating disc 15 rotates, the limiting wheel 17 slides along the track of the sliding groove 14, ensuring that the rotating disc 15 does not deviate from the track, shake or tilt during rotation. The rotating disc 15 can rotate at a predetermined angle and speed under the control of the servo motor 19. 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.

[0024] like Figure 1 , Figure 6 As shown, the flip 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 mounted on the top surface of the rotating disk 15. The positioning piece 22 is fixedly mounted on the upper end of the connecting piece 21 through four pillars. The four corners of the positioning piece 22 are also connected to dampers 23 respectively. The bottoms of both sides of the positioning piece 22 are movably connected to buffer plates 24. Both sides of the two buffer plates 24 are connected to the bottom of the dampers 23. The mounting base 25 is fixedly mounted on the top surface of the buffer plate 24.

The other end of the first connecting rod 29 is connected to the side of the second positioning seat 27, so that the second positioning seat 27 is rotated and adjusted 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 stepper motor 31 starts to work, and drives the triangular chuck 33 to rotate through the connecting plate connected to its output end and the second connecting rod 32. 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 is carried out under the precise control of the stepper motor, ensuring that the monitoring room 43 can quickly and stably monitor the construction site 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 adjusting the angle of the monitoring room 43, the damper 23 can effectively absorb the vibration and impact force generated by the equipment during rotation, thereby ensuring the stability of the monitoring image and the service life of the equipment. During the operation of the entire flip assembly, the coordinated cooperation of various components ensures that the monitoring room 43 can flexibly adapt to the complex needs in the construction site environment without sacrificing stability, thereby achieving accurate and comprehensive safety monitoring.

[0025] like Figure 1 , Figure 7 , Figure 8 As shown, the cleaning assembly includes fixed blocks 34 fixedly mounted on both sides of the top surface of the second positioning seat 27, the two fixed blocks 34 are both inverted L-shaped, an upwardly arched top plate 35 is fixedly mounted between the two fixed blocks 34, the curvature of the top plate 35 is adapted to the spherical curvature of the monitoring chamber 43, a plurality of cleaning brushes 36 are arranged on the bottom surface of the top plate 35, a lower connecting block 40 is fixedly mounted on one side of the two fixed blocks 34 away from the monitoring chamber 43, a plurality of telescopic rods 41 are fixedly mounted on one side of the lower connecting block 40 close to the monitoring chamber 43, the telescopic ends of the plurality of telescopic rods 41 are sleeved with return springs 42, a scraper 37 is movably mounted on one end of the top plate 35 close to the monitoring chamber 43, the scraper 37 is used to scrape off the residue on the cleaning brush 36, the scraper 37 is fixedly connected to the telescopic ends of the plurality of monitoring chambers 43 on both sides of the side away from the monitoring chamber 43, an L-shaped extension plate 38 is fixedly mounted on both sides of the scraper 37, a trigger rod 39 is fixedly mounted between the two extension plates 38, and the trigger rod 39 is arranged in a circular arc shape; When the monitoring chamber 43 is driven by the second stepper motor 31 to rotate vertically to a certain angle, its top will gradually approach the cleaning component. As the monitoring chamber 43 continues to rotate, the first thing it contacts is the trigger rod 39, which is fixed between the two extension plates 38. At this time, the trigger rod 39 is pushed by the monitoring chamber 43, driving the extension plate 38 and the scraper 37 to move to one side, so that the scraper 37 starts to scrape off the residue on the cleaning brush 36, ensuring that the cleaning brush 36 is in the best condition. As the monitoring chamber 43 continues to rotate, the outer surface of the monitoring chamber 43 will contact the cleaning brush 36 at the bottom of the top plate 35. Since the curvature of the top plate 35 is the same as the spherical curvature of the monitoring chamber 43, The cleaning brush 36 is adapted to 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 smooth contact during the cleaning process. When cleaning is completed, the monitoring chamber 43 rotates away from the cleaning component, and the scraper 37 is automatically reset to the initial position driven by the reset spring 42. At this time, the scraper 37 contacts the cleaning brush 36 again to completely scrape off the residue on the cleaning brush 36. During the whole process, the cleaning component relies on the rotation drive of the monitoring chamber 43 and the automatic adjustment of the mechanical structure to complete the adaptive cleaning of the monitoring chamber 43, ensuring that the monitoring equipment is always in good working condition.
