Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Depend on Figure 1-5 As shown, a fencing device for foundation pit construction includes a baffle plate and supporting mechanisms on both sides of the baffle plate. This enhances the overall stability of the fencing device, better resisting external impacts and wind forces, and ensuring safe isolation of the foundation pit construction area. The baffle plate comprises two or more baffle plate components hinged together.

[0025] The baffle assembly includes a first baffle 100 and a second baffle 103. The two first baffles 100 are hinged together by a hinge 101, facilitating the opening and closing of the fencing device. It can be folded up for transportation and storage, saving space. During installation, the angle can be flexibly adjusted according to the shape and size of the pit, improving the applicability of the fencing device. A quick-connect mechanism 109 is provided between the first baffles 100 and the second baffle 103, making the assembly of the fencing more convenient and faster, improving construction efficiency. A limiting mechanism 110 is also provided between the two first baffles 100 to limit the angle between them. The first baffles 100 and the second baffle 103 are provided with several through holes 102 and reflective stickers 108. The through-hole 102 can promote air circulation inside and outside the enclosure, reduce humidity and harmful gas concentration in the construction area, improve the construction environment, and benefit the health of construction workers. The reflective sticker 108 can reflect light in low-light environments, significantly improve the visibility of the enclosure, and play a clear warning role to passing pedestrians and vehicles, reminding them to pay attention to the foundation pit construction area ahead, avoid accidental collision with the enclosure or accidentally entering the dangerous construction area, thereby effectively reducing the probability of safety accidents and ensuring traffic safety around the construction site.

[0026] The quick-connect mechanism 109 includes an insertion rod 10901 fixed to the second baffle 103 and an insertion cylinder 10903 fixed to the first baffle 100. The insertion rod 10901 is L-shaped, and its end is provided with a tapered head 10902. The insertion rod 10901 is inserted into the insertion cylinder 10903. Through the insertion and engagement of the insertion rod 10901 and the insertion cylinder 10903, coupled with the tapered head 10902 at one end of the insertion rod 10901, the insertion rod 10901 can be quickly and accurately inserted into the insertion cylinder 10903, achieving a tight connection between the second baffle 103 and the first baffle 100.

[0027] The limiting mechanism 110 includes a fixed shaft 11001 fixed to any of the first baffles 100, a limiting hook 11002 sleeved on the fixed shaft 11001, and a limiting rod 11003 fixed to the other first baffle 100, and a limiting ring 11004 fixed to the limiting rod 11003. The limiting hook 11002 is engaged with the limiting rod 11003. The limiting hook 11002 can flexibly engage or disengage from the limiting rod 11003, thereby conveniently limiting the movement of the hinge 101.

[0028] The support mechanism includes a clamping frame 104 located on the side of the second baffle 103, a bottom bracket 105 located at the bottom of the second baffle 103, and a support frame 106 fixed to the clamping frame 104 and the bottom bracket 105. The clamping frame 104 is H-shaped, the bottom bracket 105 is U-shaped, and the support frame 106 has fixing plates 107 on both sides of its bottom, allowing for a secure connection to the ground or other foundation structures via bolts or other fixing methods. This further enhances the support capacity of the support frame 106 and the overall stability of the fence. The mechanism effectively clamps the baffles, facilitating connections between them. The U-shaped bottom bracket 105 better conforms to the ground or other support structures, increasing the contact area with the support surface and thus improving the stability of the fence bottom, reducing the risk of tilting or collapse due to instability at the bottom.

[0029] Working Principle: During use, the first baffle 100 and hinge 101 facilitate the opening and closing of the fencing device. It can be folded up for transportation and storage, saving space. During installation, the angle can be flexibly adjusted according to the shape and size of the pit, and the fixed plate positions the angle, improving the applicability of the fencing device. The second baffle 103 and quick-connect mechanism 109 make the assembly of the fencing more convenient and faster, improving construction efficiency. It also facilitates the adjustment of the width of the fencing device. A support frame 106 is installed on one side of the clamping frame 104 and one side of the bottom bracket 105, enhancing the overall stability of the fencing device and better resisting external impacts and wind forces, ensuring the safety of the pit. The safety isolation of the construction area is achieved through the setting of fixed shaft 11001, limiting hook 11002, limiting rod 11003, and limiting ring 11004. This allows the limiting hook 11002 to flexibly engage or disengage from the limiting rod 11003, thus conveniently restricting the movement of hinge 101. The insertion of rod 10901 into insert cylinder 10903, along with the conical head 10902 at one end of rod 10901, facilitates quick and accurate insertion of rod 10901 into insert cylinder 10903, achieving a tight connection between the second baffle 103 and the first baffle 100. The "H"-shaped clamping frame 104 effectively clamps the baffles, facilitating connection between them. The base bracket 1... 05 is U-shaped, which allows it to better fit the ground or other supporting structures, increasing the contact area with the supporting surface and thus improving the stability of the bottom of the fence. This reduces the risk of the fence tilting or collapsing due to instability at the bottom. A pair of fixing plates 107 are installed on both sides of the bottom of the support frame 106, allowing for a secure connection to the ground or other foundation structures via bolts or other fixing methods. This further enhances the supporting capacity of the support frame 106 and the overall stability of the fence. Several through holes 102 are provided at the top and bottom of one end face of the first baffle 100 and the top and bottom of one end face of the second baffle 103, promoting air circulation inside and outside the fence and reducing the risk of damage to the construction area. The reduced humidity and harmful gas concentration within the area improve the construction environment and benefit the health of construction workers. Reflective stickers 108 are affixed to the center of the other end face of both the first baffle 100 and the other end face of the second baffle 103, reflecting light in low-light conditions and significantly increasing the visibility of the enclosure. This serves as a clear warning to pedestrians and vehicles, alerting them to the presence of a construction pit ahead and preventing accidental collisions or entry into dangerous construction areas. This effectively reduces the probability of accidents and ensures traffic safety around the construction site. Furthermore, this invention effectively achieves folding and width adjustment functions, meeting diverse construction site needs and possessing high practical value.
