Description

Technical Field

[0001] The present invention relates to the technical field of safety supervision, and in particular to an online supervision system and a supervision method based on building construction safety. Background Art

[0002] The current online construction safety supervision system usually refers to the construction safety alarm, which can monitor the safety status of the construction site and send out alarm signals in time when abnormal conditions are detected. With the functions of real-time monitoring, rapid response, anti-theft function, video recording and remote monitoring, it can effectively remind on-site managers and construction workers to pay attention to safety and take timely measures to prevent and respond to potential safety risks. In the prior art, construction safety alarms are usually installed at key locations on the construction site, such as entrances and exits, work areas, crowded or evacuation passages, and construction material storage areas. To ensure that the monitoring coverage is wide enough, most construction alarms are located in more conspicuous locations inside the construction site or at the edge of the construction area. Moreover, construction sites are usually remote and sparsely populated. When non-construction personnel want to steal construction materials at night, they are likely to scout the site in advance during the day, destroy the construction alarm at night, and then steal under the cover of darkness. The probability of success is high, and it is difficult to retain evidence afterwards, which is not conducive to the police to solve the case. In addition, since the construction safety alarm is in a long-term fixed state after installation, and the weak light when working at night attracts small insects and animals, it is easy for them to tend to build nests inside it. However, since there are several electronic devices inside the alarm, it is easy to be damaged, thus affecting the service life of the construction alarm.

While the fan-shaped plate is swinging, the bolts can be slid on the inner wall of the slide groove through the setting of the slide groove, and the position can be adjusted and fixed at will, thereby changing the length of the long rod, so that the swing amplitude of the fan-shaped plate can be adjusted, and finally changing the wiping time of the camera, so as to achieve the effect of fully wiping the camera in different geographical environments and weather conditions; 3. Through the setting of the anti-corrosion vibration mechanism, when the gear makes intermittent reciprocating rotation, the eccentric wheel can move synchronously, and the extrusion effect of the arc-shaped convex block is utilized, in conjunction with the second spring and the limit slide plate, so that the construction alarm can intermittently vibrate, which helps to shake off dead branches and leaves and accumulated water in rainy and snowy weather, reducing the time they remain on the surface of the protective shell to prevent long-term corrosion of the protective shell. At the same time, when the protective shell shakes, in conjunction with the mimicry of the folding leaves spreading their wings, the protective shell can further increase its ability to repel insects and animals.

[0020] The effects achieved by this embodiment are as follows: In the prior art, when non-construction personnel want to steal construction materials at night, they are likely to scout the area in advance during the day, destroy the construction alarm at night, and then steal under the cover of darkness. The probability of success is relatively high, and it is difficult to retain evidence afterwards, which is not conducive to the police's investigation of the case. Compared with the prior art, through the implementation of this embodiment, a mimicry insect repellent mechanism 6 is set to set the exterior of the protective shell 1 of the construction alarm to camouflage color, and it is installed in the woods outside the construction area, which has strong concealment and effectively prevents non-construction personnel from scouting and destroying it. Even if other construction alarms are destroyed and non-construction personnel successfully steal construction materials at night, they can also sound an alarm and retain evidence through this type of construction alarm hidden outside. The folding leaves 61 simulate the process of bird wings spreading, flying and then recovering, which can effectively deter smaller animals and insects in the woods from nesting in the protective shell 1.

[0021] For further examples, please refer to Figure 1 , Figure 2 , Figures 7 to 9 As shown: The anti-corrosion vibration mechanism 7 includes a pair of limiting slides 75 fixedly connected to the outer wall of the middle part of the protective shell 1, the outer walls of the pair of limiting slides 75 are slidably connected with a nail plate 72, the top and bottom of the limiting slide 75 are fixedly connected with a second spring 73, one end of the second spring 73 away from the limiting slide 75 is fixedly connected to the inner wall of the nail plate 72, and the four corners of the nail plate 72 away from the protective shell 1 are rotatably connected with a mounting ring 71; The anti-corrosion vibration mechanism 7 also includes an eccentric wheel 74.

The end of the rotating shaft 611 is fixedly connected to the eccentric wheel 74. The top of the eccentric wheel 74 is slidably connected to an arc-shaped protrusion 76. The outer wall of the arc-shaped protrusion 76 is fixedly connected to the inner wall of the nail plate 72. The top of the nail plate 72 is provided with a rotation groove adapted to the outer diameter of the eccentric wheel 74; Among them: a pair of vertical sliding grooves matching the size of the limiting sliding plate 75 are opened in the middle of the nail plate 72, and the nail plate 72 is used to enhance the stability of the device installation.

[0022] The effects achieved by this embodiment are as follows: In the prior art, small insects and animals tend to build nests inside the safety alarm, but since there are several electronic devices inside the alarm, it is easy to be damaged, thus affecting the service life of the construction alarm. Compared with the prior art, through the implementation of this embodiment, the anti-corrosion vibration mechanism 7 can utilize the squeezing effect of the arc-shaped protrusion 76, cooperate with the second spring 73 and the limiting slide plate 75, so that the construction alarm intermittently shakes, assists in shaking off dead branches and leaves and accumulated water in rainy and snowy weather, and reduces the time they remain on the surface of the protective shell 1 to prevent long-term residence and corrosion of the protective shell 1. At the same time, when the protective shell 1 shakes, the mimicry of the folding leaves 61 can be used to further enhance the protective shell 1 The strength of the expelling insects and animals.

[0023] Embodiment 2 of the present invention: A supervision method based on an online supervision system for building construction safety, comprising the following steps: Step 1: Installation stage: The construction alarm is set to camouflage color, and the construction personnel firmly connect the construction alarm to the tree trunk outside the construction area through the anti-corrosion vibration mechanism 7 and the rope; Step 2: Detection and judgment stage: The construction alarm uses built-in sensors and infrared cameras 5 devices to monitor the safety status of the construction site during the day and at night in real time, and presets parameter conditions for illegal intrusion and equipment failure to monitor the alarm; Step 3: Alarm stage: When an abnormal situation occurs, the construction alarm sounds an alarm through the loudspeaker 2, and reminds the on-site management personnel and construction personnel to pay attention to safety through the warning light 3 and text messages; Step 4: Recording stage: After the alarm is sounded, the construction alarm will record the abnormal situation, including the time, location and type of occurrence, to facilitate management personnel to analyze and handle, and to retain physical evidence in the event of night burglary.

[0024] The complete usage steps and working principle of the above embodiment are as follows: In the initial state: the folding leaf 61 is in a folded state, the top of the ball 615 is away from the top of the lower arc rod 618, and the first spring 620 and the second spring 73 are both in a naturally relaxed state.

[0025] Working process: When in use, the servo motor 65 is started to drive the short rod 66 to rotate, so that the long rod 67 is pulled back and forth, and then the long rod 67 drives the fan-shaped plate 62 to swing back and forth, so that the bristles 68 are constantly brushing the surface of the camera 5 to remove dust or impurities on the surface. In addition, since the bolt 613 can be slid on the inner wall of the slide groove 612 to adjust the position to be fixed, it is equivalent to extending or shortening the diameter of the long rod 67, so that the swing amplitude of the fan-shaped plate 62 can be adjusted. When the swing amplitude of the fan-shaped plate 62 is large, the brush bristles 68 brush the surface of the camera 5 for a long time, otherwise the brushing time is short. In this way, the swing amplitude of the fan-shaped plate 62 can be controlled according to the actual use environment of the camera 5 to improve the wiping effect of the camera 5. Furthermore, when the sector plate 62 swings, since the arc-shaped rack 63 is slidably connected to the outer wall of the sector plate 62, when the gear 64 rotates to the edge of the arc-shaped rack 63, the sector plate 62 swings back again. At this time, the arc-shaped rack 63 remains stationary due to inertia. The sector plate 62 is first swung to the other side of the arc-shaped rack 63. At this time, the gear 64 will rotate on the surface of the arc-shaped rack 63, that is, the intermittent reciprocating rotation effect of the gear 64 is achieved, which helps to increase the authenticity of the simulated bird wing flight. Whenever the gear 64 rotates, the pressure column 69 is driven to rotate through the fixed column 616. When the pressure column 69 passes through the ball 615, it squeezes it. On the one hand, the ball 615 approaches the circular groove on the top of the lower arc rod 618, and at the same time, the ball rotating under the action of the lever principle The ball 615 causes the upper arc rod 614 to tilt in the opposite direction, and the folded folding leaf 61 is unfolded through the upper arc rod 614, and the folding leaf 61 forms a shape of a bird's wing in cooperation with the lower arc rod 618. On the other hand, the movement of the servo motor 65 causes the rotating rod 619 to slide out of the inner wall of the ball 615 by one end. At this time, the first spring 620 is compressed. When the pressure column 69 rotates away and no longer squeezes the ball 615, the ball 615 can be reset by the upper arc rod 614's own gravity and the elastic force of the first spring 620, and the folding leaf 61 is retracted again. In this way, the folding leaf 61 can simulate the process of the bird's wings unfolding and flying and then being recovered, which can effectively deter smaller animals and insects in the woods from nesting in the protective shell 1 to prevent damage to the electronic parts inside the protective shell 1. Please refer to the above working process Figures 1 to 7 .

[0026] Furthermore, when the gear 64 makes intermittent reciprocating rotation, it can also synchronously drive the rotating shaft 611 to rotate, and the eccentric wheel 74 located on the rotating shaft 611 also makes synchronous movement. Whenever the eccentric side of the eccentric wheel 74 rotates to the position of the arc-shaped protrusion 76, the eccentric wheel 74 will squeeze the arc-shaped protrusion 76, so that the rotating shaft 611 and the protective shell 1 move downward as a whole. When the protective shell 1 moves downward, it will squeeze the second spring 73 at the bottom through the limiting slide plate 75, stretch the second spring 73 at the top, and then When the eccentric part of the eccentric wheel 74 leaves the arc-shaped protrusion 76, the protective shell 1 is reset by the elastic force of the second spring 73, and the protective shell 1 is reciprocated in this way, so that the protective shell 1 as a whole will intermittently shake, and the dead branches and leaves on the protective shell 1 and the accumulated water in rainy and snowy weather can be fully shaken off, reducing the time they remain on the surface of the protective shell 1 to prevent the protective shell 1 from corroding for a long time. At the same time, when the protective shell 1 shakes, the mimic wings of the folding leaves 61 can be coordinated to further strengthen the protective shell 1 to drive away insects and animals; Please refer to the above working process Figure 1 , Figure 2 , Figures 7 to 9 .
