[0021] like Figures 1 to 9 As shown, the present invention proposes a green and environmentally friendly engineering foundation pit safety protection device, comprising a protection device body 1 installed on the foundation pit, the array is arranged on the foundation pit, the lower part of the protection device body 1 is obliquely inserted into the inner surface of the foundation pit, and the upper outer side of the protection device body 1 is provided with a vertical protection plate 13 in an H-shaped structure, and the lower part of the vertical protection plate 13 is filled and compacted with heavy objects; The protective device body 1 includes a mounting plate body 11, an extension portion 12, an inclined load-bearing mechanism 14, and the vertical protective plate 13 is fixed to the end of the mounting plate body 11. The extension portion 12 is clamped on the side of the mounting plate body 11 away from the vertical protective plate 13. The inclined load-bearing mechanism 14 is arranged below the mounting plate body 11. The vertical protective plate 13 is fixed to the ground near the foundation pit. The mounting plate body 11 extends toward the middle of the foundation pit, and the extension portion 12 covers the top of the foundation pit. When the protective device body 1 is installed, the inclined load-bearing mechanism 14 is obliquely inserted into the inner surface of the foundation pit; the surface of the mounting plate body 11 is provided with an adjustment groove 111, and the adjustment groove 111 is adjusted from the mounting plate body 11 to the mounting plate body 11. The middle part of the mounting plate body 11 extends toward the side of the mounting plate body 11 away from the vertical protective plate 13. A cylinder 142 is provided at the lower side of the extension part 12 corresponding to the adjustment groove 111. One end of the oblique plug plate 141 is connected to the cylinder 142, and the other end is connected to the side of the mounting plate body 11 close to the vertical protective plate 13 through a 143. Both ends of the oblique plug plate 141 do not abut against the mounting plate body 11. Both ends of the cylinder 142 are connected to the extension part 12 and the oblique plug plate 141 through a rotating shaft. When the cylinder 142 shrinks the output shaft, the oblique plug plate 141 moves toward the cylinder 142 and shortens the distance between it and the mounting plate body 11. The oblique insert plate 141 can adjust the distance between it and the mounting plate body 11 as needed by driving the cylinder 142. When the oblique insert plate 141 is inserted into the inner surface of the foundation pit, it forms an oblique support structure with the inner wall of the foundation pit. This oblique support structure can transmit the reaction force of the side wall of the foundation pit to the entire protective device body 1, thereby enhancing the overall stability of the protective device, making it difficult to tip over or shift when it is subjected to external forces such as pedestrian collisions. Since the extension 12 covers the top of the foundation pit, and the oblique insert plate 141 can extend to the middle of the foundation pit, the coverage of the protective device body 1 is expanded. This structural design enables the protective device to better protect the area above the foundation pit and prevent pedestrians or objects from accidentally falling into the foundation pit. In addition, through the drive of the cylinder 142, the position of the oblique insert plate 141 can be flexibly adjusted according to the actual size and shape of the foundation pit. This adjustable design enables the protective device to adapt to foundation pits of different sizes and shapes without large-scale changes to the device. For example, when the foundation pit is narrow or shallow, the degree of extension and contraction of the cylinder 142 can be adjusted so that the oblique insert plate 141 can adapt to the inner surface of the foundation pit, thereby achieving a protective effect.

[0022] A filling mechanism 15 is provided between the mounting plate 11 and the cylinder 142. The filling mechanism 15 includes an airbag 151, a rubber block 152 and a plate 153. The airbag 151 covers the surface of the plate 153. One end of the airbag 151 is connected to the end of the plate 153, and the other end is connected to the plate 153 through the rubber block 152. A one-way valve 154 for filling air is provided on the surface of the airbag 151. The plate 153 is an L-shaped curved plate. The rubber block 152 is arranged on one side of the abutment plate 153 near the bend. When the filling mechanism 15 is arranged at the lower end of the mounting plate 11, the abutment plate 153 abuts against the surface of the cylinder 142, and the rubber block 152 abuts against the end of the oblique plug plate 141. The one-way valve 154 fills air into the airbag 151 through an external air compressor to expand the airbag 151, and the oblique plug plate 141 is lifted up by the rubber block 152 and the abutment plate 153. The working principle is as follows: After the installation of the protective device body 1 is completed, the filling mechanism 15 is installed in the oblique load-bearing mechanism 14. The specific operation is to place the L-shaped bending structure of the abutment plate 153 at the lower end of the mounting plate body 11 so that it abuts against the surface of the cylinder 142, and the rubber block 152 abuts against the end of the oblique plug plate 141. The airbag 151 covers the surface of the abutment plate 153, one end of which is connected to the end of the abutment plate 153, and the other end is connected to the abutment plate 153 through the rubber block 152. Through an external air compressor, air is injected into the airbag 151 through the one-way valve 154. As the airbag 151 expands, its volume increases, pushing the rubber block 152 and the abutment plate 153 to move downward. Since the rubber block 152 contacts the end of the oblique plug plate 141, the expansion force of the airbag 151 is transmitted to the oblique plug plate 141 through the rubber block 152, so that it is lifted up. When the cylinder 142 shrinks the output shaft, the oblique plug plate 141 will move toward the cylinder 142. At this time, the filling mechanism 15 plays a key role. Since the airbag 151 has been expanded and filled between the oblique plug plate 141 and the mounting plate body 11, the rubber block 152 and the abutment plate 153 will form a certain support and buffering effect with the oblique plug plate 141. This support effect can effectively limit the swing back angle of the oblique plug plate 141, prevent it from swinging excessively or retreating, thereby ensuring the stable insertion of the oblique plug plate 141 on the inner surface of the foundation pit. In actual use, the filling mechanism 15 not only plays a fixing and limiting role during installation, but also provides buffering when the protective device is impacted by external forces. For example, when a pedestrian accidentally collides with the protective device, the elasticity of the airbag 151 can absorb part of the impact force, reduce damage to the oblique plug plate 141 and the inner wall of the foundation pit, and maintain the stability of the device.

[0023] The filling mechanism 15 limits the swinging angle of the oblique plug plate 141 through the expansion of the airbag 151 and the support of the rubber block 152. This design ensures that the oblique plug plate 141 is stably inserted into the inner surface of the foundation pit. Even when it is impacted by external force, it will not be easily displaced or retreated. This is in sharp contrast to the instability of traditional protective fences and greatly improves the reliability of the protective device. The elastic characteristics of the airbag 151 enable it to absorb impact force when it is subjected to external force, reducing damage to the oblique plug plate 141 and the inner wall of the foundation pit. This buffering effect not only protects the device itself, but also avoids loosening or damage to the device caused by external force impact, thereby further enhancing the stability of the protective device. The filling mechanism 15 can be dynamically adjusted according to actual needs. By controlling the inflation amount of the airbag 151, the insertion depth and angle of the oblique plug plate 141 can be adjusted to make it better adapt to foundation pits of different sizes and shapes. This flexibility and adaptability are not available in traditional protective fences, which can effectively improve the practicality and safety of the protective device. Furthermore, the extension portion 12 includes a fixed plate monomer 121 and a movable plate 122. The movable plate 122 is connected to the end of the fixed plate monomer 121 through a rotating shaft. A C-shaped buckling portion is provided on the side of the fixed plate monomer 121 away from the vertical protective plate 13, and a C-shaped buckling portion is provided on the side of the movable plate 122 close to the buckling portion. When the movable plate 122 is unfolded, 1221 is abutted against the buckling portion surface of the fixed plate monomer 121; the end of the side of the movable plate 122 away from the mounting plate body 11 is connected to the end of the oblique plug plate 141 away from the movable plate 122 through a connecting rope. When the cylinder 142 pushes the oblique plug plate 141 to embed into the inner side of the foundation pit, the oblique plug plate 141 pulls and tightens the connecting rope.

[0024] In the foundation pit safety protection device, the stability of the movable plate 122 is significantly improved through the linkage mechanism of the connecting rope and the oblique plug plate 141. When the cylinder 142 pushes the oblique plug plate 141 to embed into the inner side of the foundation pit, the oblique plug plate 141 will pull the connecting rope to make it in a taut state. This taut connecting rope applies a downward pulling force to the movable plate 122, firmly fixing the movable plate 122 on the fixed plate monomer 121. Since the movable plate 122 is connected to the fixed plate monomer 121 through a rotating shaft, this pulling force not only limits the upward flipping of the movable plate 122, but also further enhances the bonding strength between it and the fixed plate monomer 121 through the abutment relationship between the buckle part and 1221. This structural design enables the movable plate 122 to remain stable when it is impacted by external force, and will not easily loosen or shift, thereby effectively improving the stability and reliability of the entire protection device and ensuring the safety protection effect of the area above the foundation pit.

[0025] Furthermore, the vertical guard plate 13 includes a guard plate body 131 and a load plate 132. The side of the guard plate body 131 is provided with an extension portion 1311 extending obliquely downward. The load plate 132 is inserted into the extension portion 1311 from bottom to top. The extension portion 1311 is provided with a card slot 1312. The surface of the load plate 132 is provided with a plurality of positioning holes 1321. When the load plate 132 is inserted into the lower end of the extension portion 1311, a rivet 1313 is sequentially passed through the positioning hole 1321 and the card slot 1312 to form a fixation. The load plate 132 protrudes from the side of the oblique plug plate 141. The lower part of the load plate 132 is a bent structure, and the lower part of the load plate 132 extends toward a side away from the mounting plate body 11. A cavity for filling heavy objects is provided between the extension portion 1311 and the guardrail plate body 131, and the height of the lower end surface of the load-bearing plate 132 is lower than the height of the lower end surface of the mounting plate body 11; The load-bearing plate 132 is inserted into the extension 1311 and fixed to the guardrail body 131 by rivets 1313. The design of multiple positioning holes 1321 allows the insertion depth of the load-bearing plate 132 to be adjusted according to actual needs, so as to adapt to the size and protection requirements of different foundation pits. The rivet 1313 passes through the positioning hole 1321 and the slot 1312 to ensure that the connection between the load-bearing plate 132 and the extension 1311 is firm to prevent loosening due to external impact. The cavity between the extension 1311 and the guardrail body 131 is used to fill heavy objects, such as sand, stones or concrete. These heavy objects are supported and fixed by the lower bending structure of the load-bearing plate 132, which increases the weight and stability of the vertical protective plate 13. The height of the lower end surface of the load-bearing plate 132 is lower than the height of the lower end surface of the mounting plate body 11, so that the heavy objects can be better distributed at the bottom of the entire protective device, further lowering the center of gravity of the device and enhancing its anti-overturning ability.

[0026] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
