Description

Technical Field

[0001] The utility model relates to the technical field of construction site fences, and specifically relates to a safety protection fence for construction sites. Background Technique

[0002] Construction site fences are important facilities to ensure construction safety and maintain site order. They can effectively isolate the construction site, prevent non-construction personnel from entering, and avoid the occurrence of safety accidents. The setting of construction site fences should follow the principles of safety, warning, practicality, and aesthetics. The fence material should be strong and durable, capable of withstanding adverse weather and external environment influences.

[0003] The utility model with the existing authorization announcement number CN217949987U discloses a construction safety protection fence, including a base. A limit plate is arranged above the base. A plurality of first grid bars are fixedly connected between the base and the limit plate. A lifting plate is slidably sleeved outside the first grid bars. A plurality of second grid bars are fixedly connected to the upper side of the lifting plate. The tops of the second grid bars all pass through the limit plate and are fixedly connected with a reinforcement plate. A locking box is fixedly connected to the upper side of the middle part of the lifting plate. Locking rods are slidably embedded on both sides of the locking box.

[0004] Adopting the above technical solution, the utility model provides a construction safety protection fence. The swing plate can rotate out of the groove, which can effectively increase the support force-bearing area and play an auxiliary support role. The fixing property is good. Push the lifting plate upward, so that the first grid bars and the second grid bars are fully extended, which can increase the protection height of the protection fence. In the folded state, it can reduce the transportation and storage space, which greatly facilitates the construction process of the protection fence, and is flexible and portable. However, in the above technical solution, when the safety protection fence is in use, due to a large number of building materials inside the construction site, some lawbreakers may climb over the fence to steal materials inside the construction site, and the fence itself does not have a good warning effect, so it cannot effectively drive away lawbreakers, resulting in the problem of poor practicability.

[0005] Therefore, those skilled in the art provide a safety protection fence for construction sites to solve the problems raised in the above background technique. Content of the Utility Model

[0030] The working principle of the present utility model is as follows: When in use, first, the staff transports the device to a suitable position for use. Then, the power supplies of the alarm 303, the pressure sensor 304, and the controller 307 are turned on to enable them to be in a stable power-on state, avoiding power-off during use. After that, the staff firmly fixes the base 1 of the device with four bolts 4 and installs the fence body 301 inside the two support columns 2. Subsequently, it is reinforced with the fixing pin 6 and the nut 8. Then, the pressure sensor 304 and the controller 307 are turned on for warning work. When an illegal person tries to climb up through the fence body 301, since pressure will be exerted on the lifting frame 302 during the climbing process, the lifting frame 302 and the pressing block 305 on the surface of the lifting frame 302 will move downward. When the pressing block 305 moves, it can squeeze and contract the spring 306. At the same time, when the lifting frame 302 descends, it will exert pressure on the pressure sensor 304. The pressure sensor 304 can sense the pressure signal and convert it into an electrical signal, and send it to the controller 307 in the form of an electrical signal. The controller 307 can control the alarm 303 to start alarm work after receiving the signal, so as to drive away the illegal person and avoid the theft of building materials inside the construction site, thus greatly improving the warning function of the device. Finally, the lifting frame 302 will bounce back to its original position under the action of the elastic force of the spring 306 for subsequent warning work.
