Description

Technical Field

[0001] This invention relates to the field of construction site environmental monitoring technology, specifically to a smart construction site environmental monitoring device. Background Technology

[0002] Construction sites are springing up everywhere. During construction, dust and noise pollution caused by construction workers, equipment carrying mud and soil, scattering building materials, and construction machinery is extremely serious, becoming one of the main causes affecting urban air quality. To effectively control dust and noise, many construction sites are equipped with smart construction site environmental monitoring devices. These devices typically include dust concentration detectors and noise detectors. The dust concentration detectors can be connected to a sprinkler dust suppression system via the Internet of Things (IoT), which can adjust the spray size according to the dust concentration. The dust concentration detector measures dust concentration by drawing outside air into its detection chamber.

[0003] However, the monitoring of traditional smart construction site environmental monitoring devices and their coordination with sprinkler dust suppression systems are affected by strong winds. The wind carries dust in one direction, while the sprinkler dust suppression system is set up around the perimeter of the construction site. This can easily lead to the other three sides of the sprinkler dust suppression system spraying clean air, resulting in a waste of water resources. Furthermore, due to the uncertainty of wind direction, the detection port of the dust concentration detector may be facing away from the wind direction. Since the mass of dust is greater than that of air, dust is more likely to avoid the detection port of the dust concentration detector on the leeward side due to inertia, resulting in the detection data of the dust concentration detector being lower than the actual value.

[0004] Based on this, the present invention designs a smart construction site environmental monitoring device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a smart construction site environmental monitoring device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a smart construction site environmental monitoring device, comprising a mobile vehicle housing and a multi-section electric telescopic rod. The upper middle part of the mobile vehicle housing is fixedly connected to the fixed end of the multi-section electric telescopic rod. A fixed plate is fixedly connected to the top of the multi-section electric telescopic rod. A fixed shaft is fixedly connected to the upper middle part of the fixed plate. A cross-shaped base plate is rotatably connected to the outer wall of the fixed shaft. A dust concentration detector is fixedly connected to one upper end of the cross-shaped base plate. The detection end of the dust concentration detector is located away from the fixed shaft. On one side of the shaft, a wind direction and speed detector and a noise detector are fixedly connected to two opposite ends on the upper side of the cross base plate, respectively. The dust concentration detector, wind direction and speed detector, and noise detector can all be connected to the Internet of Things. A rotating sleeve is rotatably connected to the end of the cross base plate away from the dust concentration detector. A connecting rod is fixedly connected to the outer wall of the rotating sleeve.

[0007] As a further embodiment of the present invention, the automatic locking mechanism includes a rotating ring, a driven swing plate, and a plurality of locking teeth. The locking teeth are all fixed to the outer wall of the fixed shaft and arranged in a circumferential array. The locking teeth are all located below the cross-shaped base plate. The rotating ring is located on the common outer side of the locking teeth. The rotating ring is rotatably connected to the fixed disk and fixedly connected to the cross-shaped base plate. A sliding sleeve is fixedly connected to the side of the rotating ring near the rotating sleeve. A locking block is slidably connected inside the sliding sleeve. One end of the locking block, away from the rotating sleeve, extends into the rotating ring and can be inserted into the gap between two adjacent locking teeth. The other end of the locking block is fixed. A contact head is connected between a sliding sleeve and a rotating sleeve. A first spring is sleeved on the outer side of the sliding sleeve between the rotating ring and the contact head. The driven swing plate is fixedly connected to the side of the rotating sleeve near the contact head. The end of the driven swing plate away from the rotating sleeve can contact the protruding end in the middle of the contact head. Side baffles are symmetrically fixedly connected to the left and right sides of the rotating ring on the first spring. Limiting hooks located between the contact head and the driven swing plate are fixedly connected to the inner side of each side baffle. The two limiting hooks can contact the wing plates on both sides of the contact head. A second spring is fixedly connected between the driven swing plate and the two side baffles.

[0008] As a further embodiment of the present invention, a roller is rotatably connected to one end of the driven swing plate near the contact head, and an arc-shaped groove is provided on the end face of the protruding end of the contact head. The arc-shaped groove is concentrically arranged with the rotation axis of the rotating sleeve, and the arc-shaped groove can contact the outer surface of the roller.

[0009] As a further embodiment of the present invention, an electric track is installed at the bottom of the mobile vehicle housing, and a stabilizing support mechanism is provided on the mobile vehicle housing. The stabilizing support mechanism includes two grooves, which are respectively located on both sides of the mobile vehicle housing. A first extended leg is rotatably connected to one end of each groove, and a second extended leg is rotatably connected to the other end of each groove. The first extended leg is located below the second extended leg, and the length of the first extended leg is less than the length of the second extended leg. A first hydraulic cylinder facing downwards is fixedly connected to the end of each first extended leg away from the mobile vehicle housing, and a first pad is fixedly connected to the free end of each first hydraulic cylinder. A second hydraulic cylinder facing downwards is fixedly connected to the end of each second extended leg away from the mobile vehicle housing, and a second pad is fixedly connected to the free end of each second hydraulic cylinder. A driving mechanism for driving the first and second extended legs to rotate simultaneously is provided on the mobile vehicle housing.

[0010] As a further embodiment of the present invention, the driving mechanism includes a bidirectional threaded rod and a motor. Both ends of the bidirectional threaded rod are rotatably connected to the two end walls inside the mobile vehicle housing. A first moving block is threadedly connected to one end of the outer surface of the bidirectional threaded rod. The first moving block is slidably connected to the bottom wall inside the mobile vehicle housing. First racks are symmetrically fixedly connected to both sides of the first moving block, each rack meshing with a first gear. The first gear is fixedly connected to the rotation shaft of the first extension leg on the same side. A second moving block is threadedly connected to the end of the outer surface of the bidirectional threaded rod away from the first moving block. The second moving block is slidably connected to the bottom wall inside the mobile vehicle housing. Second racks are symmetrically fixedly connected to both sides of the second moving block, each rack meshing with a second gear. The second gear is fixedly connected to the rotation shaft of the second extension leg on the same side. The motor is fixedly connected to the outer wall of the mobile vehicle housing, and one end of the bidirectional threaded rod extends outside the mobile vehicle housing and is fixedly connected to the output end of the motor.

[0011] As a further embodiment of the present invention, the motor is model Y280M-2.

[0012] As a further embodiment of the present invention, a camera is installed at the top of the fixed shaft, and the height of the camera is higher than the height of the dust concentration detector, the wind direction and speed detector, and the noise detector.

[0013] As a further embodiment of the present invention, the wind direction guide plate is configured as an arc-shaped structure, with the inner side of the arc facing the rotating sleeve.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention enables the dust concentration detector to always face the windward direction by setting a wind direction guide plate, and ensures that the windward side of the wind direction and wind speed detector is not obstructed by other instruments or structures. This allows the dust concentration detector and the wind direction and wind speed detector to accurately detect the concentration of dust and wind speed in the air, respectively. Both the dust concentration detector and the wind direction and wind speed detector can transmit the detected data to the sprinkler dust suppression system around the construction site via the Internet of Things. The sprinkler dust suppression system can determine the activation of the sprinkler device on the corresponding side based on the wind direction data, determine the activation time of the sprinkler device on that side based on the wind speed, and determine the appropriate spray size based on the detected dust concentration. This achieves good dust suppression effect while minimizing water waste.

[0016] 2. The automatic locking mechanism in this invention can automatically release the fixed shaft when the wind direction guide plate rotates significantly with the wind, allowing the cross base plate to rotate freely with the fixed shaft. It can also automatically lock the fixed shaft when the wind direction guide plate rotates to the windward side of the fixed shaft, fixing the cross base plate relative to the fixed shaft. This prevents the cross base plate from being affected by the slight swaying of the wind direction guide plate, allowing the various detection instruments on the cross base plate to collect data smoothly. This avoids the impact of shaking on the accuracy of the detection of each instrument and prevents potential damage to the instruments. The arc-shaped groove in this invention ensures that the locking block and contact head do not experience slight displacement when the driven swing plate oscillates slightly within the range of the arc-shaped groove, preventing slight shaking of the cross base plate and further ensuring the safety and accuracy of the detection of the various instruments on the cross base plate.

[0017] 3. The present invention can greatly increase the support range of the bottom of the mobile vehicle shell through the stable support mechanism, thereby improving the stability of the monitoring device and its resistance to tipping when the monitoring device is raised to a high altitude in strong winds, and ensuring that the device can be used normally in strong winds.

[0026] Please see Figure 1-6 This invention provides a technical solution: a smart construction site environmental monitoring device, comprising a mobile vehicle housing 1 and a multi-section electric telescopic rod 2. The upper middle part of the mobile vehicle housing 1 is fixedly connected to the fixed end of the multi-section electric telescopic rod 2. A fixed plate 3 is fixedly connected to the top of the multi-section electric telescopic rod 2. A fixed shaft 4 is fixedly connected to the upper middle part of the fixed plate 3. A cross-shaped base plate 5 is rotatably connected to the outer wall of the fixed shaft 4. A dust concentration detector 6 is fixedly connected to one end of the upper side of the cross-shaped base plate 5. The detection end of the dust concentration detector 6 is located on the side of the dust concentration detector 6 away from the fixed shaft 4. The two opposite ends of the upper side of the cross base plate 5 are respectively fixedly connected to a wind direction and speed detector 7 and a noise detector 8. The dust concentration detector 6, the wind direction and speed detector 7 and the noise detector 8 can all be connected to the Internet of Things. The end of the cross base plate 5 away from the dust concentration detector 6 is rotatably connected to a rotating sleeve 9. The outer wall of the rotating sleeve 9 is fixedly connected to a connecting rod 10. The end of the connecting rod 10 away from the rotating sleeve 9 is fixedly connected to a wind direction guide plate 11. An automatic locking mechanism is provided between the rotating sleeve 9 and the fixed shaft 4. The automatic locking mechanism can fix the cross base plate 5 and the fixed shaft 4 relative to each other.

[0027] When the above solution is put into practical use, the dust concentration detector 6 and wind direction and speed detector 7 in the monitoring device are connected to the sprinkler dust suppression system around the construction site via the Internet of Things. After the monitoring device is moved to the construction site, it can raise the dust concentration detector 6, wind direction and speed detector 7, and noise detector 8 to a suitable height via a multi-section electric telescopic pole 2 (this height needs to be determined according to the actual surrounding conditions, as long as the height of the dust concentration detector 6, wind direction and speed detector 7, and noise detector 8 is higher than the surrounding obstacles) to prevent the surrounding obstacles from affecting the detection results of the dust concentration detector 6, wind direction and speed detector 7, and noise detector 8. When the wind picks up, the wind direction guide plate 11 drives the cross base plate 5 to rotate under the action of the wind force until the wind direction guide plate 11 and the dust concentration detector 6 are respectively located on the windward side and the windward side of the fixed axis 4, so that the windward side of the wind direction and speed detector 7 and the noise detector 8 is unobstructed, and the detection of the dust concentration detector 6 is ensured. The device is positioned so that the dust concentration detector 6 is always facing the windward direction. This ensures that the windward side of the wind direction and speed detector 7 is not obstructed by other instruments or structures, allowing the dust concentration detector 6 and wind direction and speed detector 7 to accurately detect the dust concentration and wind speed in the air, respectively. Both the dust concentration detector 6 and the wind direction and speed detector 7 can transmit the detected data to the sprinkler dust suppression system outside the construction site via the Internet of Things. The sprinkler dust suppression system can determine the activation of the corresponding sprinkler device based on the wind direction data, the activation time based on the wind speed, and the spray size based on the detected dust concentration, thus minimizing water waste while achieving good dust suppression. The noise detector 8 in the monitoring device can monitor the noise level at the construction site, preventing excessive noise from affecting nearby residents.

[0028] As a further embodiment of the present invention, the automatic locking mechanism includes a rotating ring 13, a driven swing plate 14, and a plurality of locking teeth 15. The plurality of locking teeth 15 are all fixed to the outer wall of the fixed shaft 4 and arranged in a circumferential array. The plurality of locking teeth 15 are all located below the cross base plate 5. The rotating ring 13 is located on the common outer side of the plurality of locking teeth 15. The rotating ring 13 is rotatably connected to the fixed disk 3 and fixedly connected to the cross base plate 5. A sliding sleeve 16 is fixedly connected to the side of the rotating ring 13 near the rotating sleeve 9. A locking block 17 is slidably connected inside the sliding sleeve 16. One end of the locking block 17 away from the rotating sleeve 9 extends into the rotating ring 13 and can be inserted into the gap between two adjacent locking teeth 15. The other end of the locking block 17 is fixedly connected to a positioning... The contact head 18 is located between the sliding sleeve 16 and the rotating sleeve 9. A first spring 19 is sleeved on the outer side of the sliding sleeve 16 between the rotating ring 13 and the contact head 18. The driven swing plate 14 is fixedly connected to the side of the rotating sleeve 9 near the contact head 18. The end of the driven swing plate 14 away from the rotating sleeve 9 can contact the protruding end in the middle of the contact head 18. Side baffles 20 are symmetrically fixedly connected to the left and right sides of the rotating ring 13 on the first spring 19. Limiting hooks 21 located between the contact head 18 and the driven swing plate 14 are fixedly connected to the inner side of each side baffle 20. The two limiting hooks 21 can contact the wing plates on both sides of the contact head 18. A second spring 22 is fixedly connected between the driven swing plate 14 and the two side baffles 20.

[0029] When the above scheme is put into actual use, the wind direction guide plate 11 rotates under the action of wind force. The wind direction guide plate 11 drives the driven swing plate 14 to rotate through the connecting rod 10 and the rotating sleeve 9. The end of the driven swing plate 14 away from the rotating sleeve 9 disengages from the protruding end of the contact head 18. The locking block 17 and the contact head 18 slide outward along the sliding sleeve 16 under the elastic force of the first spring 19 until the wing plates on both sides of the contact head 18 are blocked by the limiting hooks 21 on both sides. At this time, the locking block 17 moves away from the rotating sleeve 9. One end is completely disengaged from the gap of the retaining tooth 15, allowing the retaining tooth 15 to rotate with the fixed shaft 4. This allows the cross base plate 5 to rotate with the wind direction guide plate 11. When the wind direction guide plate 11 and the dust concentration detector 6 rotate to the windward and wind-facing sides of the fixed shaft 4 respectively, the force of the wind direction guide plate 11 driving the cross base plate 5 to rotate is greatly reduced. At this time, the driven swing plate 14 can rotate under the balanced elastic force of the two second springs 22 to press against the protruding end of the contact head 18 again, so that the contact head 18 can rotate. The contact head 18 and the locking block 17 are squeezed again, causing the locking block 17 to re-insert into the gap of the locking tooth 15 in its current position, thereby fixing the rotating ring 13 and the cross base plate 5. At this time, the wind direction guide plate 11 will also swing back and forth slightly under the fluctuation characteristics of the airflow, and cause the driven swing plate 14 to swing slightly within the range of the protruding end of the contact head 18. In this way, the automatic locking mechanism in the monitoring device can automatically release the fixed shaft 4 when the wind direction guide plate 11 rotates with the wind, allowing the cross base plate 5 to rotate freely with the fixed shaft 4, and can automatically lock the fixed shaft 4 when the wind direction guide plate 11 rotates to the windward side of the fixed shaft 4, so that the cross base plate 5 is relatively fixed with the fixed shaft 4, so that the cross base plate 5 is not affected by the slight swing of the wind direction guide plate 11, and the various detection instruments on the cross base plate 5 can collect data smoothly, avoiding the impact of shaking on the accuracy of the detection of each detection instrument, and avoiding the situation where shaking may cause damage to the detection instruments.

[0030] As a further embodiment of the present invention, a roller 23 is rotatably connected to one end of the driven swing plate 14 near the contact head 18. An arc-shaped groove 24 is provided on the end face of the protruding end of the contact head 18. The arc-shaped groove 24 is concentrically arranged with the rotation axis of the rotating sleeve 9. The arc-shaped groove 24 can contact the outer surface of the roller 23. During operation, the setting of the roller 23 can greatly reduce the friction between the driven swing plate 14 and the contact head 18, and can prevent the driven swing plate 14 from being stuck by the contact head 18. The setting of the arc-shaped groove 24 can ensure that when the driven swing plate 14 swings slightly within the range of the arc-shaped groove 24, the locking block 17 and the contact head 18 do not undergo slight displacement, and prevent slight shaking of the cross base plate 5, further ensuring the safety and detection accuracy of each instrument on the cross base plate 5.

[0031] As a further embodiment of the present invention, an electric track 12 is installed at the bottom of the mobile vehicle housing 1. The mobile vehicle housing 1 is provided with a stabilizing support mechanism, which includes two grooves located on both sides of the mobile vehicle housing 1. A first extension leg 25 is rotatably connected to one end of each groove, and a second extension leg 26 is rotatably connected to the other end of each groove. The first extension leg 25 is located below the second extension leg 26, and the length of the first extension leg 25 is less than the length of the second extension leg 26. A first hydraulic cylinder 27 facing downwards is fixedly connected to the end of the first extension leg 25 away from the mobile vehicle housing 1. A first pad 28 is fixedly connected to the free end of the first hydraulic cylinder 27. A second hydraulic cylinder 29 facing downwards is fixedly connected to the end of the second extension leg 26 away from the mobile vehicle housing 1. A second pad 30 is fixedly connected to the free end of the second hydraulic cylinder 29. The mobile vehicle housing 1 is provided with a driving mechanism for driving the first extension leg 25 and the second extension leg 26 to rotate simultaneously.

[0032] When the above solution is put into practical use, the monitoring device can be moved to the construction site via the electric track 12. After the monitoring device is moved to the construction site, the drive mechanism drives the first extension leg 25 and the second extension leg 26 to rotate about 145 degrees away from the mobile vehicle body 1, so that the two first extension legs 25 and the two second extension legs 26 unfold to the four sides of the mobile vehicle body 1. Then, the first hydraulic cylinder 27 and the first pad 28 both begin to grow until the first pad 28 and the second pad 30 both contact the bottom surface and lift the mobile vehicle body 1 away from the bottom surface. In this way, the monitoring device can greatly increase the support range of the bottom of the mobile vehicle body 1 through the stable support mechanism, improve the stability of the monitoring device, and improve the anti-tipping ability of the monitoring device in strong winds, when the wind direction guide plate 11 and various detection instruments are raised to a high altitude, ensuring that the device can be used normally in strong winds.

[0033] As a further embodiment of the present invention, the driving mechanism includes a bidirectional threaded rod 31 and a motor 38. The two ends of the bidirectional threaded rod 31 are rotatably connected to the two end walls inside the mobile vehicle housing 1, respectively. A first moving block 32 is threadedly connected to one end of the outer surface of the bidirectional threaded rod 31. The first moving block 32 is slidably connected to the bottom wall inside the mobile vehicle housing 1. First racks 33 are symmetrically fixedly connected to both sides of the first moving block 32. Each of the first racks 33 is meshed with a first gear 34. The first gear 34 is fixedly connected to the rotation shaft of the first extension leg 25 on the same side. The outer side of the bidirectional threaded rod 31, away from the first moving block 32, is threadedly connected to a second moving block 35. The second moving block 35 is slidably connected to the inner bottom wall of the mobile vehicle housing 1. The two sides of the second moving block 35 are symmetrically and fixedly connected to second racks 36. Each of the second racks 36 is meshed with a second gear 37. The second gear 37 is fixedly connected to the rotating shaft of the second extension leg 26 on the same side. The motor 38 is fixedly connected to the outer wall of the mobile vehicle housing 1. One end of the bidirectional threaded rod 31 extends to the outside of the mobile vehicle housing 1 and is fixedly connected to the output end of the motor 38.

[0034] When the above scheme is put into actual use, the motor 38 drives the bidirectional threaded rod 31 to rotate. The bidirectional threaded rod 31 drives the first moving block 32 and the second moving block 35 to move towards or away from each other through the transmission action of the threaded structure. The first moving block 32 drives the first rack 33 to move. The first rack 33 drives the first gear 34 to rotate. The first gear 34 drives the first extension leg 25 to rotate about 145 degrees away from or towards the moving vehicle body 1, thereby unfolding or retracting the first extension leg 25. The second moving block 35 drives the second rack 36 to move. The second rack 36 drives the second gear 37 to rotate. The second gear 37 drives the second extension leg 26 to rotate about 145 degrees away from or towards the moving vehicle body 1, thereby unfolding or retracting the second extension leg 26.

[0035] As a further embodiment of the present invention, the motor 38 is model Y280M-2.

[0036] As a further embodiment of the present invention, a camera 39 is installed at the top of the fixed shaft 4. The height of the camera 39 is higher than that of the dust concentration detector 6, the wind direction and speed detector 7, and the noise detector 8. During operation, the camera 39 allows managers to monitor the construction site in real time and facilitates remote management of the construction site.

[0037] As a further embodiment of the present invention, the wind direction guide plate 11 is configured as an arc-shaped structure, with the inner side of the arc facing the rotating sleeve 9; during operation, the arc-shaped structure of the wind direction guide plate 11 can improve the wind resistance of the wind direction guide plate 11 and improve the sensitivity of the wind direction guide plate 11 to wind force.

[0038] Working Principle: The dust concentration detector 6 and wind direction and speed detector 7 in this monitoring device are connected to the sprinkler dust suppression system outside the construction site via the Internet of Things. After the monitoring device is moved to the construction site, it can raise the dust concentration detector 6, wind direction and speed detector 7, and noise detector 8 to a suitable height via a multi-section electric telescopic pole 2 (this height needs to be determined according to the actual surrounding conditions; it is only necessary to ensure that the height of the dust concentration detector 6, wind direction and speed detector 7, and noise detector 8 is higher than the surrounding obstacles) to prevent the surrounding obstacles from affecting the detection results of the dust concentration detector 6, wind direction and speed detector 7, and noise detector 8. When the wind picks up, the wind direction guide plate 11 drives the cross base plate 5 to rotate under the action of the wind force until the wind direction guide plate 11 and the dust concentration detector 6 are respectively located on the windward side and the windward side of the fixed axis 4, so that the windward side of the wind direction and speed detector 7 and the noise detector 8 is unobstructed, and the detection end of the dust concentration detector 6 is facing the wind. The device is positioned so that the dust concentration detector 6 always faces the windward direction, and the windward side of the wind direction and speed detector 7 is not obstructed by other instruments or structures. This allows the dust concentration detector 6 and the wind direction and speed detector 7 to accurately detect the concentration of dust and wind speed in the air, respectively. Both the dust concentration detector 6 and the wind direction and speed detector 7 can transmit the detected data to the sprinkler dust suppression system around the construction site via the Internet of Things. The sprinkler dust suppression system can determine the activation of the sprinkler device on the corresponding side based on the wind direction data, the activation time based on the wind speed, and the spray size based on the detected dust concentration. This achieves good dust suppression while minimizing water waste. The noise detector 8 in the monitoring device can monitor the noise level at the construction site, preventing excessive noise from affecting nearby residents.
