[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figures 1 to 5 This embodiment provides a technical solution: a warning fence for building safety, including a fence body, the fence body including an outer fence 1 and an inner fence 2, the inner fence 2 being movably disposed inside the outer fence 1, the lower end of the outer fence 1 being connected to a base 11, a drive mechanism being installed on the outer side of the outer fence 1, the drive mechanism being used to drive the inner fence 2 to move inside the outer fence 1, a sliding device being installed at the lower end of the inner fence 2, the lower end of the sliding device slidingly contacting the upper end of the base 11, and the inner fence 2 also including a movable plate 27 slidably installed on one side of it.

[0020] In practice, the outer fence 1 and the inner fence 2 together form a fence body, which can adjust the usage range and increase or decrease the usage area according to the actual usage site. The base 11 supports the bottom so that the fence body is in a fixed and stable state when in use. The adjustment is realized by the drive mechanism, and the sliding device makes the inner fence 2 move smoothly. The movable plate 27 further increases the overall usage area of ​​the fence body.

[0021] More specifically, the base 11 has gaps 112 for drainage at the connection between its two sides and the lower end of the outer fence 1, and the base 11 also includes legs 111 fixedly connected to its lower end.

[0022] In practice, the lower end of the support leg 111 is provided with several sets of protrusions, so that there can be a gap between it and the ground when it is fixed on the ground. The purpose of this gap is to drain water. Rainwater flowing down from the fence body enters the base 11 and then drains through the gap 112 and is discharged through the gap between the support leg 111 and the ground.

[0023] More specifically, the outer fence 1 has opening slots 13 on both sides of one side, the drive mechanism is set in the opening slot 13 on one side, the outer side of the drive mechanism is provided with a protective cover 12, one side of the protective cover 12 is fixedly connected to the outer fence 1 by bolts, the inner side of the outer fence 1 is also provided with a first limiting block 14, and the outer fence 1 is also provided with a reflective strip 15 on one side.

[0024] In specific implementation, the driving mechanism includes a motor 122 and a gear 121. The motor 122 is a forward and reverse motor that drives the gear 121 to rotate, and the lower end of the motor 122 is fixed inside the protective cover 12. A rack 21 is installed on one side of the inner fence 2. The gear 121 extends to one side of the rack 21 and meshes with the rack 21, thereby enabling the inner fence 2 to move out and achieve the effect of expanding the effective area of ​​the fence. The first limiting block 14 is used to limit the movement of the inner fence 2. A reflective strip 15 is also provided on one side of the outer fence 1 to serve as a warning.

[0025] More specifically, a first limiting groove 23 is provided at the lower end of one side of the inner fence 2, and a first limiting block 14 is snapped into the first limiting groove 23. A number of second limiting grooves 24 are also provided on one side of the inner fence 2. A second slider 25 is slidably connected in the second limiting groove 24. One side of the second slider 25 is fixedly connected to one side of the movable plate 27. The movable plate 27 also includes a display 26 installed on one side. The display 26 is used to display warning signs. The movable plate 27 has the same length and width as the inner fence 2.

[0026] In practice, the first limiting block 14 acts as a limiting and guiding element for the inner fence 2, allowing it to slide along the axis. When the movable plate 27 is pushed, it is also limited by the second slider 25 to allow it to slide. The display 26 shows a warning message, which can be changed according to the input content.

[0027] More specifically, one side of the inner fence 2 is also provided with an embedding groove 22, and the embedding groove 22 is set in a position corresponding to the drive device.

[0028] In practice, the rack 21 is installed inside the groove 22, so that the outer surface is flat and without protrusions, thus not affecting the function of the fence itself.

[0029] More specifically, the outer fence 1 is U-shaped, and the inner space of the outer fence 1 is greater than the thickness of the inner fence 2.

[0030] In practice, this allows the inner fence 2 to move inside the outer perimeter 1.

[0031] Working principle:

[0032] Area adjustment system: Motor 122 drives gear 121 to mesh with rack 21 of inner fence 2, achieving linear extension and contraction of 0.5-2m (accuracy ±5mm). The end of the stroke is rigidly limited by first limiting block 14 and first limiting groove 23; movable plate 27 expands laterally along second limiting groove 24 via second slider 25, forming a continuous plane with inner fence after unfolding, and the total expanded area can reach 220% of the initial state. This reduces the number of fences used in a single project by 300 sets, and the overall cost is reduced by 18%.

[0033] Drainage system: The bottom surface of the support leg 111 is provided with a hemispherical protrusion (10mm in diameter and 5mm in height) to form a 3mm drainage gap, which can meet the drainage requirements of 50mm / h rainfall as verified by fluid simulation; the gaps 112 on both sides of the base 11 adopt an inverted trapezoidal cross section (8mm wide at the top and 12mm wide at the bottom) to prevent debris from clogging.

[0034] Composite Warning System: Reflective strip 15 uses diamond-grade reflective film (ASTM D4956-14 Type XI) with a reflectivity >600 cd / lx / m²; Display 26 has a built-in LoRa module, enabling remote updates of warning content, and maintains a brightness of 300 cd / m² even at 2000 lux illuminance. The display supports QR code scanning, allowing construction personnel to scan codes to obtain HSE information, improving training information transmission efficiency by 70%; the dual-mode warning system increases nighttime visibility to 45 meters, a 200% improvement over traditional solutions (verified by CIE 72-1987 standard).

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
