Description

Technical Field

[0001] The present invention relates to an integrated monitoring device, in particular to an integrated monitoring device for the whole environment of construction projects based on the Internet of Things, and belongs to the technical field of construction projects. Background Art

[0002] The integrated monitoring device for the whole environment of construction projects integrates technologies such as sensors, video monitoring, and data processing to conduct real-time dynamic monitoring of the environmental parameters (temperature, humidity, dust, harmful gases, etc.), structural safety (settlement, inclination, stress and strain), equipment operation status (working parameters of tower cranes and elevators), and construction progress at the construction site, and has the capabilities of multi-dimensional data collection, intelligent analysis, and risk warning.

[0003] At present, during the actual use of monitoring devices, they cannot provide safety protection in the case of the device being impacted by falling objects from a height and bottom collision impacts. When the monitoring camera is impacted by mechanical collisions at the construction site (such as the operation of excavators and cranes) or falling objects from a height, it will cause physical damage to the device, resulting in device shutdown and interruption of data collection, requiring frequent repair and replacement, increasing the operation and maintenance costs, as well as the service life of the device.

[0004] Therefore, an integrated monitoring device for the whole environment of construction projects based on the Internet of Things is designed to optimize the above problems. Summary of the Invention

[0005] The main purpose of the present invention is to provide an integrated monitoring device for the entire environment of a construction project based on the Internet of Things. By installing the monitoring body on a hemispherical mounting seat and providing a force storage rotation mechanism at the positions corresponding to the axis on both sides of the hemispherical shell, the hemispherical mounting seat can be continuously applied with a rotational force during normal use, and the position of the hemispherical mounting seat can be limited by a plug-in limit mechanism during normal use, and then used in conjunction with a downward-pressing unlocking mechanism, a rotating buffer mechanism and an upward-pressing unlocking mechanism, the device can not only provide buffering protection when impacted by falling objects from a high altitude, but also be within the impact range of falling objects from a high altitude. In the case of a large accident, the locking state of the plug-in limit mechanism can be released, and the power storage rotation mechanism can release the rotation force, control the hemispherical mounting seat to drive the monitoring body to rotate, and hide the monitoring body inside the shell for safety protection. In addition, when the bottom of the monitoring body is collided and squeezed, the upward pressure unlocking mechanism can also release the locking state of the plug-in limit mechanism, and the monitoring body is protected from rotation, which improves the safety of use. The plug-in limit mechanism composed of the installation slot, the plug-in block, the first spring, the slot, and the ball bearing, when in normal use, the plug-in block is inserted into the inside of the slot for limitation, and the hook-shaped guard plate, the second spring, and the pull rope are used to form a plug-in limit mechanism. The unlocking mechanism is pressed down for use. When a falling object from a high altitude impacts all the hook-shaped guard plates, the lock of the plug-in limit mechanism is released and the monitoring body is hidden. When only a single hook-shaped guard plate is impacted, the locking state of the plug-in limit mechanism is not completely released. Instead, the hook-shaped guard plate is used in conjunction with the second spring for elastic buffering, and a rotating buffering mechanism composed of a lower sleeve, a slip ring, a ball cage universal joint, a third spring, a limit ring, an upper sleeve, a partition, a spiral rod, and a strip through groove is used. At the same time, when the shell is subjected to impact force, the downward movement of the shell is controlled, and the ball cage universal joint is used to cause the shell to deviate outward to avoid it. In addition, during the downward movement of the shell, the spiral rod passes through the strip through groove The groove will also control the rotation of the outer shell and perform rotational force unloading, which can improve the impact protection effect during use. The upward pressure unlocking mechanism composed of a fixed seat, a slide groove, a hidden groove, a through hole, a protrusion, a fitting plate, and a fourth spring can control the upward movement of the outer shell when the monitoring body is subjected to an upward force. The protrusion on the side of the fixed seat is used to squeeze the ends of multiple groups of hook-shaped guard plates to unlock the plug-in limit mechanism, control the rotation protection of the monitoring body, and adopt a purely mechanical structure of linkage control protection. In high-risk and high-pollution environments such as construction projects, it can significantly improve the survivability and protection timeliness of the monitoring equipment, and is more practical.

[0019] To make the technical personnel in the technical field more clear and definite about the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the implementation manners of the present invention are not limited thereto.

[0020] As Figures 1 - 8 shown, this embodiment provides a building engineering full - environment integrated monitoring device based on the Internet of Things, including a hemispherical mounting seat 1; The monitoring body 2 is installed on the horizontal end surface of the hemispherical mounting seat 1. The hemispherical mounting seat 1 and the monitoring body 2 form a spherical shape. The outer side of the hemispherical mounting seat 1 is provided with an outer shell 3. At the positions corresponding to the axis on both sides inside the outer shell 3, there is an energy - storage rotation mechanism 4, and the energy - storage rotation mechanism 4 applies a vertical - plane rotation force to the hemispherical mounting seat 1; Between the inner side of the outer shell 3 and the top of the hemispherical mounting seat 1, a plug - in limiting mechanism 5 is evenly arranged. The outer shell 3 locks the position of the hemispherical mounting seat 1 through the plug - in limiting mechanism 5; On the outer side of the outer shell 3, a down - pressure unlocking mechanism 6 is evenly arranged along the circumferential direction. The down - pressure unlocking mechanism 6 corresponds to the plug - in limiting mechanism 5, and the down - pressure unlocking mechanism 6 respectively releases the locking of the plug - in limiting mechanism 5 on the hemispherical mounting seat 1; At the middle position of the top of the outer shell 3, there is a rotation buffer mechanism 7; The top of the rotary buffer mechanism 7 is provided with an upper pressure unlocking structure 8, and the upper pressure unlocking structure 8 releases the locking of the hemispherical mounting seat 1 by multiple sets of plug-in limiting mechanisms 5.

[0021] Overall working principle: During normal use, the energy storage rotary mechanism 4 always applies a force for vertical plane rotation to the hemispherical mounting seat 1. However, due to the limitation of the hemispherical mounting seat 1 by the plug-in limiting mechanism 5, the stability of the hemispherical mounting seat 1 during use is ensured. But when a high-altitude falling object lands on the lower pressure unlocking mechanism 6, it will first be buffered and protected, and then the locking state of the plug-in limiting mechanism 5 at the corresponding position will be released. If there are many high-altitude falling objects, multiple lower pressure unlocking mechanisms 6 are simultaneously impacted. At this time, multiple sets of plug-in limiting mechanisms 5 are unlocked simultaneously, and the hemispherical mounting seat 1 is released. The energy storage rotary mechanism 4 controls the rotation of the hemispherical mounting seat 1 and the monitoring body 2, hiding the monitoring body 2 inside the housing 3 for protection. Additionally, during the impact of the high-altitude falling object, the rotary buffer mechanism 7 is used for buffering and protection to reduce the impact force on the device. When the bottom of the monitoring body 2 is collided by construction machinery and moves upward, the upper pressure unlocking structure 8 will simultaneously release the locking state of the plug-in limiting mechanism 5, releasing the hemispherical mounting seat 1 to protect the monitoring body 2.

[0022] In this embodiment, the energy storage rotary mechanism 4 includes a groove 401, a shaft rod 402, and a hairspring 403. The grooves 401 are symmetrically opened on the inner side of the housing 3. Shaft rods 402 are rotatably installed at the middle positions of the end faces of the grooves 401. The outer ends of the shaft rods 402 are fixedly connected to the sides of the hemispherical mounting seat 1. Hairsprings 403 are provided on the outer sides of the shaft rods 402. The two ends of the hairsprings 403 are respectively fixedly connected to the shaft rods 402 and the sides of the grooves 401.

[0023] The hairspring 403 is made of 65Mn spring steel, with an elastic coefficient k = 50 N·m / rad and a pre-compression amount θ = π rad; The shaft rod 402 and the groove 401 are rotationally connected through a deep groove ball bearing, and the bearing clearance is controlled between 0.01 - 0.03 mm; Local working principle: During normal use, the hairspring 403 is in a compressed state. After unlocking the hemispherical mounting seat 1, the hairspring 403 controls the hemispherical mounting seat 1 to rotate 180 degrees around the shaft rod 402 to hide and protect the monitoring body 2.

[0024] In this embodiment, the plug-in limit mechanism 5 includes an installation groove 501, a plug 502, a first spring 503, and a slot 504. The installation grooves 501 are evenly arranged in a circular array on the inner top of the housing 3. The installation grooves 501 are perpendicular to the inner surface of the housing 3. Plug blocks 502 are slidably arranged inside the installation grooves 501 in the direction towards the hemispherical mounting seat 1. First springs 503 are arranged between the plug blocks 502 and the inner ends of the installation grooves 501. Slots 504 that cooperate with the plug blocks 502 are provided on the outer side of the top of the hemispherical mounting seat 1. The ends of the plug blocks 502 are inserted into the slots 504.

[0025] The cross-section of the plug block 502 is rectangular (8mm×6mm), the insertion depth is 10mm, and the clearance between it and the slot 504 is ≤0.05mm; The first spring 503 is made of stainless steel spring wire, with a free length of 20mm, a pre-compression of 5mm, and provides an initial locking force of 20N; Local working principle: In the normal use state, the first spring 503 exerts an elastic force to squeeze the plug block 502 into the slot 504 to prevent the rotation of the hemispherical mounting seat 1. When unlocking the locking state of the hemispherical mounting seat 1, the plug block 502 can be pulled into the installation groove 501.

[0026] In this embodiment, balls 505 are rotatably installed at the bottom ends of the plug blocks 502. The outer sides of the balls 505 are in contact with the end faces of the slots 504. The diameter of the balls 505 is 3mm, the material is GCr15 bearing steel, and the surface roughness Ra≤0.8μm to ensure smooth rotation.

[0027] Local working principle: The setting of the balls 505 can reduce the wear between the end of the plug block 502, the hemispherical mounting seat 1, and the outer glass cover of the monitoring body 2, changing the sliding friction to rolling friction.

[0028] In this embodiment, the downward pressing unlocking mechanism 6 includes a hook-shaped guard plate 601, a second spring 602, and a pull rope 603. The hook-shaped guard plates 601 are evenly arranged circumferentially on the outer side of the top of the housing 3. The top ends of the hook-shaped guard plates 601 are hinged to the housing 3. The number of the hook-shaped guard plates 601 is the same as that of the plug-in limit mechanisms 5. Second springs 602 are arranged between the inner sides of the hook-shaped guard plates 601 and the housing 3. A pull rope 603 is fixedly installed between the outer side of the top end of the hook-shaped guard plate 601 and the plug block 502. The pull rope 603 is slidably connected to the housing 3.

[0029] The hook-shaped guard plate 601 is made of aluminum alloy LY12, with a thickness of 2mm, a hook angle of 120°, and the distance from the rotation fulcrum to the top end is 5mm; The elastic coefficient k of the second spring 602 is 10N / mm, the initial compression is 8mm, and the critical impact force for triggering unlocking is ≥50N; The material of the pull rope 603 is aramid fiber, with a diameter of 1 mm and a breaking tensile force ≥ 200 N; Local working principle: After a high-altitude falling object impacts the hook-shaped guard plate 601, the second spring 602 is used for buffering, and the hook-shaped guard plate 601 rotates downward with the connection point between the top and the outer shell 3 as the axis. The top end of the hook-shaped guard plate 601 applies an upward pulling force to the pull rope 603, pulling the insertion block 502 into the inside of the installation groove 501, thereby unlocking the locking of the hook-shaped guard plate 601 to the hemispherical mounting seat 1.

[0030] In this embodiment, four groups of hook-shaped guard plates 601 are provided, and the sides of adjacent hook-shaped guard plates 601 are in contact with each other.

[0031] Local working principle: During the use of the device, only when all four groups of hook-shaped guard plates 601 are impacted by high-altitude falling objects will the hemispherical mounting seat 1 be completely unlocked.

[0032] In this embodiment, the rotary buffer mechanism 7 includes a lower sleeve 701, a slip ring 702, a constant velocity joint 703, a third spring 704, a limit ring 705, and a horizontal rotation assembly. The lower sleeve 701 is located at the middle position of the top of the outer shell 3. The bottom of the lower sleeve 701 is in contact with the top of the outer shell 3. A slip ring 702 is vertically slidably arranged inside the lower sleeve 701. A third spring 704 is fixed between the top end of the slip ring 702 and the inner top of the lower sleeve 701. The inner side of the slip ring 702 is installed with a constant velocity joint 703 through a bearing. The movable end at the bottom of the constant velocity joint 703 is fixedly connected to the outer shell 3. The inner top of the lower sleeve 701 is provided with a horizontal rotation assembly for controlling the rotation of the constant velocity joint 703. A limit ring 705 is horizontally fixed at the inner bottom end of the lower sleeve 701.

[0033] The model of the constant velocity joint 703 is WJ-08, with a maximum allowable swing angle of 30° and an axial bearing capacity of 500 N; The pitch of the screw rod 708 is 8 mm, and the clearance fit with the strip-shaped through groove 709 is 0.2 mm to ensure synchronous rotation during downward movement; The third spring 704 is made of piano wire, with a free length of 50 mm, a pre-compression amount of 10 mm, and a maximum compression stroke of 20 mm, providing a buffer damping force; Local working principle: After being impacted by a falling object, the outer shell 3 applies a downward pulling force to the slip ring 702 through the constant velocity joint 703, and the third spring 704 is used for buffering. The outer shell 3 will be separated from the lower sleeve 701. Since the constant velocity joint 703 can rotate in the vertical plane, the movable end at the bottom of the constant velocity joint 703 can drive the outer shell 3 to swing and avoid in a direction away from the stress point, reducing the impact force again.

[0034] In this embodiment, the horizontal rotation assembly includes an upper sleeve 706, a partition plate 707, a screw rod 708, and a strip-shaped through groove 709. The upper sleeve 706 is fixed to the top of the lower sleeve 701. A partition plate 707 is horizontally fixed between the upper sleeve 706 and the lower sleeve 701. The top end of the constant velocity joint 703 is vertically fixed with a screw rod 708. A strip-shaped through groove 709 is formed at the middle position of the partition plate 707. The screw rod 708 passes through the inside of the strip-shaped through groove 709.

[0035] Local working principle: When the constant velocity joint 703 moves vertically downward, it will drive the vertical downward movement of the screw rod 708. During the downward movement of the screw rod 708, due to being limited by the strip-shaped through groove 709, the screw rod 708 will drive the constant velocity joint 703 to rotate horizontally, thereby controlling the rotation of the housing 3 and performing rotational force unloading to further reduce the impact force of the falling object.

[0036] In this embodiment, the upper pressing and unlocking structure 8 includes a fixed seat 801, a sliding groove 802, a hidden groove 803, a through port 804, a protrusion 805, a fitting plate 806, and a fourth spring 807. The fixed seat 801 is located at the top of the lower sleeve 701. A sliding groove 802 is formed at the bottom end of the fixed seat 801. The lower sleeve 701 is vertically slidably disposed inside the sliding groove 802. A hidden groove 803 is formed at the top end of the fixed seat 801. A through port 804 is formed between the sliding groove 802 and the hidden groove 803. A fourth spring 807 is provided between the top end of the lower sleeve 701 and the inner top of the sliding groove 802. The upper sleeve 706 passes through the inside of the fourth spring 807 and the through port 804 and extends into the hidden groove 803. A fitting plate 806 that fits against the inner bottom of the hidden groove 803 is fixed to the top end of the upper sleeve 706. A protrusion 805 is provided at the bottom end of the outer side of the fixed seat 801, and the cross-section of the protrusion 805 is conical.

[0037] The taper of the protrusion 805 is 1:2, the height is 15 mm, and the bottom diameter is 20 mm, ensuring that the rotation angle of the hook-shaped guard plate 601 is ≥15° when pressed; The elastic coefficient k of the fourth spring 807 is 20 N / mm, the initial compression amount is 5 mm, and unlocking is triggered when the housing 3 moves up 3 mm; Local working principle: The installation position of the fixed seat 801 is fixed. When the bottom of the monitoring body 2 is collided by construction machinery and moves upward, the housing 3 drives the sleeve to move upward. The fourth spring 807 can be used for buffer protection. During the upward movement of the housing 3, the protrusion 805 on the outer side of the fixed seat 801 will simultaneously extrude a plurality of hook-shaped guard plates 601 outward. The pulling ropes 603 on the hook-shaped guard plates 601 will pull the insertion blocks 502 into the installation grooves 501, releasing the locking state of the hemispherical mounting seat 1. The hemispherical mounting seat 1 drives the monitoring body 2 to rotate into the protection state. When the device needs to be reset, only the maintenance personnel need to rotate the hemispherical mounting seat 1 by 180 degrees to lock it again, and the operation is very convenient.

[0038] In this embodiment, mounting holes are uniformly formed on the outer side of the top end of the fixed seat 801, and the mounting holes are distributed in an annular array.

[0039] Local working principle: The arrangement of the mounting holes facilitates the installation and fixation of the device using bolts.

[0040] As described above, only further embodiments of the present invention are provided, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and concept of the present invention, makes equivalent substitutions or changes, all of which fall within the protection scope of the present invention.
