DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0021] The present application provides an alarm-type construction fence, which is mainly used to solve the problem that there is no alarm warning function, so some people still climb over the fence to enter the construction site, which poses a safety hazard, and provides the following technical solutions, which will be described in detail below:

[0022] Embodiment 1:

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, in some embodiments, it includes a symmetrically arranged base plate 1, a universal wheel 2 is fixedly installed at the bottom of the base plate 1 and a supporting mechanism 3 is arranged on the top of the base plate 1, and an adjusting rod 4 for adjusting the length is evenly arranged between the two supporting mechanisms 3, and also includes an alarm mechanism 5 close to the base plate 1 for alarm; wherein the alarm mechanism 5 is fixed to an infrared sensor 501 on the supporting outer plate 301, and an infrared probe 502 is embedded in the infrared sensor 501, wherein a buzzer 503 is fixed on the top of the supporting inner plate 303, and the infrared sensor 501 is electrically connected to the buzzer 503.

[0024] Specifically: the symmetrical setting of the base plate 1 can increase the overall stability of the fence and prevent the fence from tipping over; the alarm mechanism 5 close to the base plate 1 can monitor activities around the fence and trigger an alarm when someone enters illegally, which can effectively remind the staff and managers at the construction site to take timely measures to prevent illegal entry and reduce safety hazards.

[0025] The working principle here is: the infrared sensor 501 is a sensor that can detect infrared radiation in the surrounding environment. When a person or object approaches the fence, its body temperature will generate infrared radiation. The infrared sensor 501 can detect that a person or an object enters the vicinity of the fence by sensing the changes in the surrounding infrared rays; the infrared probe 502 is the core part of the infrared sensor 501, which can receive and convert infrared signals. The infrared probe 502 is usually embedded in the sensor so as to accurately sense the changes in infrared radiation; the buzzer 503 is a sound emitting device, which can generate a specific sound according to the received electrical signal. In this embodiment, the buzzer 503 is installed on the top of the supporting inner plate 303. When the infrared sensor 501 detects that a person or an object enters the vicinity of the fence, an alarm signal will be triggered, and the signal will be transmitted to the buzzer 503, and the buzzer 503 will emit a warning sound; the infrared sensor 501 and the buzzer 503 are connected through a circuit. When the infrared sensor 501 detects that a person or an object enters the vicinity of the fence, a trigger signal will be sent to the buzzer 503 through the circuit. After receiving the signal, the buzzer 503 will emit a sound, which can effectively remind the staff and management personnel at the construction site to take timely measures to prevent illegal entry and reduce safety hazards.

[0026] like Figure 1 , Figure 2 As shown, in some embodiments, the support mechanism 3 includes a support outer plate 301 fixed on the base plate 1, a reinforcing rod 302 is symmetrically fixed to the outer side of the support outer plate 301, a support inner plate 303 slides inside the support outer plate 301, a bolt 304 is threadedly connected to the support outer plate 301, and the end of the bolt 304 abuts against the support inner plate 303. The working principle here is: the support outer plate 301 provides structural stability and supporting force by being fixed to the base plate 1, and the reinforcing rod 302 is symmetrically fixed to the outer side of the support outer plate 301 to increase the strength and rigidity of the structure; a threaded hole is provided on the support outer plate 301, and the bolt 304 passes through the threaded hole and abuts against the support inner plate 303. By rotating the bolt 304, the height of the bolt 304 can be adjusted to control the position of the support inner plate 303, and the end of the bolt 304 abuts against the support inner plate 303 to provide a stable supporting force.

[0027] like Figure 1 , Figure 2 , Figure 3As shown, in some embodiments, the adjustment rod 4 includes an adjustment inner rod 401 symmetrically fixed between the support outer plate 301 and the support inner plate 303 and an adjustment outer rod 402 arranged between the support outer plate 301 and the support inner plate 303, the adjustment outer rod 402 has openings at both ends and the adjustment inner rod 401 slides in the adjustment outer rod 402, and a limiting mechanism 6 is arranged at the connection between the adjustment outer rod 402 and the adjustment inner rod 401; the limiting mechanism 6 includes a limiting block 601 fixedly connected to the end of the adjustment outer rod 402, the outer wall of the limiting block 601 is threadedly connected with a limiting cylinder 602, and the end of the limiting block 601 away from the adjustment outer rod 402 is fixedly connected with a limiting plate 603 of an annular array, and when the limiting cylinder 602 is tightened, it contacts the limiting plate 603 so that the limiting plate 603 limits the movement of the adjustment inner rod 401; the limiting mechanism 6 is fixed on the adjustment outer rod 402 A light strip 7 is installed, and the working principle here is: when it is necessary to limit the moving range of the adjusting inner rod 401, the operator can adjust the tightening degree of the limiting cylinder 602. Tightening the limiting cylinder 602 will cause the limiting plate 603 to contact with the adjusting inner rod 401 and apply a certain limiting force. In this way, when the adjusting inner rod 401 slides, the limiting plate 603 will limit its movement so that it moves within the set range; by appropriately adjusting the tightening degree of the limiting cylinder 602, the limiting force of the limiting plate 603 on the adjusting inner rod 401 can be controlled. A larger limiting force will more strictly limit the movement of the adjusting inner rod 401, while a smaller limiting force allows a certain degree of sliding of the adjusting inner rod 401. The height and length of the fence can be flexibly adjusted according to the needs and requirements of the specific construction site to adapt to different construction stages and working conditions.

[0028] Embodiment 2:

[0029] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:
