Description

Technical Field

[0001] The utility model relates to the technical field of edge protection, and particularly relates to a warning device for edge protection in a smart construction site. Background Technique

[0002] With the rapid development of the construction industry, the importance of construction site safety management has become increasingly prominent. The concept of a smart construction site has emerged, aiming to improve the safety management level of the construction site through advanced technical means. As an important part of the smart construction site, the edge protection warning device can effectively prevent the occurrence of construction site safety accidents, especially against illegal intrusion or accidental falls at the construction site boundary.

[0003] Existing edge protection warning devices mainly use infrared pair-beam alarms and vibration sensors to detect climbing over behavior. However, these technologies have certain limitations and defects. The infrared pair-beam alarm is easily affected by bad weather such as fog, rain, and snow, resulting in the light being blocked or refracted, thus generating false alarms. At the same time, the vibration sensor may also be mis-triggered by vibrations caused by construction machinery or vehicle driving at the construction site, which are non-climbing-over behaviors. This not only reduces the reliability of the warning device but also may bring unnecessary troubles to the construction site management, and it cannot effectively prevent people from breaking in forcefully. Content of the Utility Model

[0004] In order to overcome the above technical problems, the purpose of the present utility model is to provide a warning device for edge protection in a smart construction site. When the top of the first railing is squeezed, it will drive the round rod to slide into the U-shaped pipe, causing the first railing to slide downward, which can effectively relieve the support force of the intruder, preventing them from climbing over along the top. Then, in cooperation with the extrusion, the corresponding round rod of the second railing slides out of the U-shaped pipe, and at the same time drives the second railing to slide upward, which can effectively intercept the climber, making it difficult for the climber to climb over, and improving the protection stability.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0052] Please refer to Figures 1-6 As shown in the figure, a smart construction site edge protection and warning device includes a protection and warning mechanism 100. The protection and warning mechanism 100 includes two first U-shaped frames 110, and the two first U-shaped frames 110 are fixed to each other. The guardrail 120 is fixed to the outer wall of one side of one of the first U-shaped frames 110. The interception mechanism 200 is fixed at the center between the two first U-shaped frames 110, and the warning mechanism 300 is fixed to the outer wall of one side of one of the first U-shaped frames 110.

[0053] The interception mechanism 200 includes the following parts: Its U-shaped tube 210 is fixed to the outer wall of the first U-shaped frame 110, and two round rods 220 are respectively slid in the two ports of the U-shaped tube 210. The first U-shaped frame 110 includes two second chutes 114, which are respectively opened on the inner walls of both sides of the first U-shaped frame 110. One railing 230 is fixed to one end of one of the round rods 220 and slides with one set of the second chutes 114. The other railing 240 is fixed to one end of the other round rod 220 and slides with the other set of the second chutes 114. A number of slide rails 211 are evenly and angularly fixed to the outer walls at both ends of the U-shaped tube 210, and the ring frame 221 slides on the outer wall of the round rod 220. A number of long rods 222 are evenly and angularly fixed to the outer wall of the ring frame 221 and slide inside the slide rails 211.

[0054] A number of strain gauge pressure sensors 231 are evenly spaced and fixed to the top wall of the railing 230, and a first rubber block 232 is fixed to the outer wall of the strain gauge pressure sensor 231. The second U-shaped frame 233 is fixed between the outer walls of a number of the first rubber blocks 232, and the inner wall of the second U-shaped frame 233 slides with the outer wall of the railing 230. The first chute 111 is opened at the bottom of one of the first U-shaped frames 110, and the arc-shaped frame 113 slides inside the first chute 111. The first hexagon head screw 112 rotates at a position on the outer wall of the first U-shaped frame 110 close to the first chute 111, and the outer wall of the first hexagon head screw 112 is screwed with the arc-shaped frame 113.

[0055] The warning mechanism 300 includes the following parts: Two rotating seats 310 are respectively fixed to the outer walls at both ends of the first U-shaped frame 110, and the third railing 320 rotates between the two rotating seats 310. The fourth railing 321 slides inside the third railing 320. A square rod 322 is fixed to one end of the fourth railing 321, and two second hexagon head screws 323 are respectively screwed at both ends of the square rod 322. A number of strain gauge pressure sensors 324 are evenly spaced and fixed to the outer wall of the square rod 322. A number of second rubber blocks 325 are respectively fixed to the outer wall of the square rod 322 at the positions of the strain gauge pressure sensors 324, and two coil springs 326 are fixed between the outer walls of the rotating seats 310 and the rotating shafts of the third railing 320.

[0056] Specifically, during operation, when an intruder climbs over the wall, the U-shaped frame II 233 at the top of the railing I 230 is squeezed, which will squeeze the rubber block I 232. The pressure received by the rubber block I 232 will be transmitted to the strain gauge pressure sensor I 231. The strain gauge pressure sensor I 231 determines whether it is a man-made squeeze by detecting the persistence and magnitude of the pressure, thereby triggering an alarm and avoiding false alarms. When the top of the railing I 230 is squeezed, it will drive the round rod 220 to slide into the U-shaped tube 210, causing the railing I 230 to slide downward. After the liquid inside the U-shaped tube 210 is squeezed, it will squeeze the corresponding round rod 220 of the railing II 240 to slide out of the U-shaped tube 210, and at the same time drive the railing II 240 to slide upward to intercept the intruder; during installation, after the long rod 222 is slidably inserted into the slide rail 211, the operator can spot-weld between the long rod 222 and the slide rail 211, which is convenient for the operator to load and unload the interception mechanism 200. When the intruder uses tools such as a ladder for assistance and tries to jump over the top of the railing I 230, the warning mechanism 300 will be within the range of the landing point. After jumping over, the intruder will land on the railing III 320 or the railing IV 321. Affected by gravity, it will drive the railing III 320 to rotate until the rubber block II 325 adheres to the bottom surface, and the pressure will be quickly transmitted to the strain gauge pressure sensor II 324. After detecting the pressure, an alarm will be issued for warning. Among them, the length between the railing III 320 and the railing IV 321 can be adjusted as needed, and the hexagonal screw II 323 is used for limiting to adjust the alarm range.

[0057] Embodiment 1

[0058] As Figures 1-3 shown, in this embodiment, the interception mechanism 200 includes the following parts: The U-shaped tube 210 is fixed to the outer wall of the U-shaped frame I 110, and two round rods 220 are respectively slidably arranged at the two ports of the U-shaped tube 210. Two sliding grooves II 114 are respectively opened on the inner walls of the two sides of the U-shaped frame I 110. One end of the railing I 230 is fixed to one of the round rods 220 and slides with one set of sliding grooves II 114, and one end of the railing II 240 is fixed to the other round rod 220 and slides with the other set of sliding grooves II 114.

[0059] In this embodiment, when the top of the railing I 230 is squeezed, it will drive the round rod 220 to slide into the U-shaped tube 210, causing the railing I 230 to slide downward, which can effectively relieve the force supported by the intruder and prevent them from climbing over the top. Coupled with squeezing the corresponding round rod 220 of the railing II 240 to slide out of the U-shaped tube 210, and at the same time driving the railing II 240 to slide upward, it can effectively intercept the climber, making it difficult for the climber and improving the protection stability.

[0060] As Figures 5-6As shown in the figure, in this embodiment, the first U-shaped frame 110 includes the following parts: a first chute 111 is opened at the bottom of one of the first U-shaped frames 110, and the arc-shaped frame 113 slides inside the first chute 111. The first hexagon screw 112 rotates at a position on the outer wall of the first U-shaped frame 110 close to the first chute 111, and the outer wall of the first hexagon screw 112 is screwed with the arc-shaped frame 113. The warning mechanism 300 includes the following parts: two rotating seats 310 are respectively fixed to the outer walls at both ends of the first U-shaped frame 110, and the third railing 320 rotates between the two rotating seats 310. The fourth railing 321 slides inside the third railing 320. A square rod 322 is fixed to one end of the fourth railing 321, and two second hexagon screws 323 are respectively screwed at both ends of the square rod 322.

[0061] During specific implementation, the length between the third railing 320 and the fourth railing 321 can be adjusted according to the needs of the installation environment, and the second hexagon screw 323 is used for limiting, so as to adjust the alarm range and effectively improve the applicability. When the protection and warning mechanism 100 is not needed for protection, the first hexagon screw 112 can be twisted to make the arc-shaped frame 113 slide into the first chute 111. The warning mechanism 300 is retracted with the first U-shaped frame 110 under the resilience of the coil spring 326, reducing the occupied space and facilitating storage or transportation.

[0062] Embodiment 2

[0063] As Figure 6 shown, in this embodiment, the warning mechanism 300 includes the following parts: a plurality of strain gauge pressure sensors 324 are equally spaced and fixed to the outer wall of the square rod 322, and a plurality of rubber blocks 325 are respectively fixed to the outer wall of the square rod 322 at the positions of the strain gauge pressure sensors 324. Two coil springs 326 are fixed between the outer wall of the rotating seat 310 and the rotating shaft of the third railing 320.

[0064] During specific implementation, when an intruder uses tools such as a ladder to assist and wants to jump over from the top of the first railing 230, the warning mechanism 300 will be within the landing range. After jumping over, it will land on the third railing 320 or the fourth railing 321. Affected by gravity, it will drive the third railing 320 to rotate until the rubber block 325 touches the bottom surface. The pressure will be quickly transmitted to the strain gauge pressure sensor 324. After detecting the pressure, an alarm will be issued. Through the warning mechanism 300, it is possible to prevent intruders from jumping into the interior with tools and escaping protection and warning, effectively increasing the trigger rate of the alarm. At the same time, when not affected by a certain gravity, the strain gauge pressure sensor 324 is in a suspended state, reducing false alarms and effectively improving the stability of the protection.
