[0002] Safety protection devices used in geological disaster control engineering construction are mainly used to prevent geological disasters such as slope landslides and debris flows, and to ensure the safety of construction personnel and the surrounding environment. They involve fields such as safety prevention, geological disaster control and engineering construction.

[0003] In existing technologies, common safety protection devices used in some geological disaster control projects include anti-slide retaining walls, which can enhance the landslide blocking effect and stabilize the slope. Other protective devices used in geological disaster control projects include fixed frames, vertical rods, bases and stabilizing mechanisms, which achieve stable installation through telescopic springs, movable blocks and the like, improving installation efficiency, and the vertical rods can be quickly disassembled.

[0004] However, in the existing technology, some safety protection devices used in the construction of geological disaster control projects are prone to damage when in use, such as protective nets, when subjected to large impact forces, which can cause injury to the workers at the bottom of the work area. Therefore, a safety protection device for the construction of geological disaster control projects is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a safety protection device for geological disaster control engineering construction, aiming to improve the problem that some existing safety protection devices for geological disaster control engineering construction are not comprehensive in their protection, and the mesh structure is easily damaged after impact, thus failing to achieve the purpose of safety protection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a safety protection device for geological disaster control engineering construction, comprising a support frame, a support plate fixedly connected inside the support frame, multiple fixed plates fixedly connected to the front side of the support plate, fixed rings fixedly connected to the four corners of the front side of the fixed plates, limit posts fixedly connected inside two pairs of fixed rings in the same vertical direction, two connecting plates rotatably connected to the outside of the two limit posts, moving posts rotatably connected inside two pairs of connecting plates in the same vertical direction, two transmission plates rotatably connected to the outside of the two moving posts, positioning posts rotatably connected inside two pairs of transmission plates in the same vertical direction, two limit rings fixedly connected to the outside of the two positioning posts, and compression plates fixedly connected to the front side of the four limit rings;

[0007] As a further description of the above technical solution: a movable block is fixedly connected to the outside of each of the two movable columns, a support block is slidably connected to the outside of the two movable blocks, and a sealed chamber is fixedly connected to the inside of the support block;

[0008] As a further description of the above technical solution: the extrusion plate is fixedly connected to the rear side of the extrusion block a, the exterior of the extrusion block a is slidably connected to the interior of the support block, the exterior of the extrusion block a is slidably connected to the interior of the sealed chamber, and the interior of the sealed chamber is slidably connected to the extrusion block b.

[0009] As a further description of the above technical solution: the support frame is externally fixedly connected to multiple positioning blocks, the positioning blocks are internally fixedly connected to limit rods, the limit rods are externally rotatably connected to rotating blocks, and the bottom of the rotating blocks is fixedly connected to an arc-shaped plate.

[0010] As a further description of the above technical solution: the positioning block is internally slidably connected to a positioning rod, the two ends of the positioning rod are fixedly connected to limit plates, the positioning rod is externally slidably connected to the outside of the arc-shaped plate, the positioning rod is externally fixedly connected to a fixing plate, and the fixing plate is externally fixedly connected to a locking hook.

[0011] As a further description of the above technical solution: a large-hole damping mesh is slidably connected inside the multiple locking hooks, and a small-hole damping mesh is slidably connected inside the multiple locking hooks; the rear side of the small-hole damping mesh is slidably connected to the front side of the multiple extrusion plates.

[0012] As a further description of the above technical solution: the rear side of the extrusion block b is fixedly connected to the front side of the fixed plate, and the exterior of the extrusion block b is slidably connected to the interior of the sealed chamber.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, when the device is subjected to an external impact, the impact force acts on the large-hole damping mesh and the small-hole damping mesh. The impact force will cause the small-hole damping mesh to push the extrusion plate to move backward. At this time, the positioning column moves backward and drives the transmission plate to rotate along the moving column. Since the moving block is inside the groove of the support block, the moving column moves to both sides and drives the connecting plate to rotate along the limiting column, thereby driving the extrusion block a and extrusion block b to squeeze the sealed chamber and increase the air pressure inside the sealed chamber. At this time, the external force disappears. By restoring the air pressure inside the sealed chamber, the extrusion plate is squeezed again to achieve position correction, thereby achieving the buffering and shock absorption effect on falling objects and preventing injury to the operators at the bottom of the operation.

[0015] 2. In this utility model, when the large-hole damping mesh and the small-hole damping mesh are locked on the fixed plate by the locking hook, the positioning rod presses the arc plate to make the rotating block rotate upward. At this time, the positioning rod is self-locked inside the positioning block, and the limiting plate restricts the horizontal displacement of the positioning rod, realizing the rapid installation and disassembly of the damping mesh and improving the work efficiency of construction personnel in setting up safety protection devices.

[0023] 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.

[0024] Reference Figure 1 , Figure 2 , Figure 3This utility model provides an embodiment of a safety protection device for geological disaster control engineering construction, including a support frame 1. The support frame 1 is made of high-strength steel, and a support plate 2 is fixedly connected inside it. The support plate 2 is a thick metal plate with good load-bearing capacity, used to provide a stable support platform for subsequent components. Multiple fixing plates 3 are fixedly connected to the front side of the support plate 2 to ensure the stability of the connection. Fixing rings 4 are fixedly connected to the four corners of the front side of the fixing plate 3. The inner wall of the fixing rings 4 is polished to fit the limiting post 5. Two pairs of fixing rings in the same vertical direction are provided. Internally, each of the two limit posts 5 is fixedly connected. Externally, each of the two limit posts 5 is rotatably connected to two connecting plates 6, which are made of alloy. Internally, each of the two pairs of connecting plates 6 in the same vertical direction is rotatably connected to a moving post 7. Externally, each of the two moving posts 7 is rotatably connected to two transmission plates 8. The transmission plates 8 are lightweight and high-strength, effectively transmitting power. Internally, each of the two pairs of transmission plates 8 in the same vertical direction is rotatably connected to a positioning post 9, ensuring smooth transmission. Externally, each of the two positioning posts 9 is fixedly connected to two limiting rings 10, which are made of a rubber and metal composite. The materials used include rubber parts for cushioning and metal parts for strength. Four limiting rings 10 are fixedly connected to the front of an extrusion plate 26, which is wear-resistant and impact-resistant. Each of the two movable columns 7 is fixedly connected to a movable block 11, made of wear-resistant plastic with internal lubrication grooves to reduce friction with the support block 12. The two movable blocks 11 are slidably connected to the outside of the support block 12, which provides stable support for other components. A sealed chamber 14 is fixedly connected inside the support block 12, providing good sealing. For sealing and pressure resistance, the rear side of the extrusion plate 26 is fixedly connected to the extrusion block a13, which is made of hard alloy material with a smooth surface and high hardness. The external side of the extrusion block a13 is slidably connected to the inside of the support block 12, and the external side of the extrusion block a13 is slidably connected to the inside of the sealed chamber 14. The inside of the sealed chamber 14 is slidably connected to the extrusion block b15, which is made of rubber and has good elasticity and cushioning performance. Through the coordinated operation of the above structures, the final result is to achieve the cushioning and shock absorption effect on falling objects to prevent injury to the operators at the bottom of the work area.

[0025] Reference Figure 3 and Figure 4The support frame 1 has multiple positioning blocks 16 fixedly connected to its exterior. These positioning blocks 16 are corrosion-resistant and wear-resistant, providing a stable installation base for subsequent components. A limit rod 17 is fixedly connected inside each positioning block 16. A rotating block 18 is rotatably connected to the outside of the limit rod 17. The rotating block 18 is made of high-strength plastic and has an internal lubrication chamber to reduce friction with the limit rod 17. An arc-shaped plate 19 is fixedly connected to the bottom of the rotating block 18. A positioning rod 20 is slidably connected inside each positioning block 16. Limit plates 21 are fixedly connected to both ends of the positioning rod 20. The limit plates 21 are made of a rubber and metal composite material. The positioning rod 20 is externally slidably connected to the outside of the arc-shaped plate 19. Through this sliding connection, the arc-shaped plate 19 can rotate and deform to a certain extent around the positioning rod 20 when under force. The positioning rod 20 is externally fixedly connected to a fixing plate 22. The fixing plate 22 is made of cast iron, has a sturdy structure, and can provide stable support for the locking hook 23. The fixing plate 22 is externally fixedly connected to a locking hook 23. The locking hook 23 is made of alloy steel, has high hardness and wear resistance, and can firmly hook the shock-absorbing net. Through the coordinated operation of the above structures, the rapid installation and disassembly of the shock-absorbing net is finally realized, which improves the work efficiency of construction personnel in setting up safety protection devices.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 Multiple locking hooks 23 are internally slidably connected to a large-hole shock-absorbing mesh 24. The large-hole shock-absorbing mesh 24 is woven from high-strength polyester fiber. The mesh is relatively large, which can allow larger stones and other objects to pass through while ensuring a certain strength, thus playing a preliminary buffering and screening role. Multiple locking hooks 23 are internally slidably connected to a small-hole shock-absorbing mesh 25. The small-hole shock-absorbing mesh 25 is composed of multiple layers of high-strength steel wire mesh. The mesh is fine and can effectively block smaller stones and debris, thus playing a fine protective role. The rear side of the small-hole shock-absorbing mesh 25 is slidably connected to the front side of multiple extrusion plates 26. When the extrusion plates 26 move, they can cause the small-hole shock-absorbing mesh 25 to deform to a certain extent, further enhancing the protective effect. The rear side of the extrusion block b15 is fixedly connected to the front side of the fixed plate 3. The extrusion block b15 is made of rubber and has good elasticity and sealing performance. The exterior of the extrusion block b15 is slidably connected to the interior of the sealed chamber 14. During the sliding process, the extrusion block b15 can change the pressure inside the sealed chamber 14.

[0027] Working Principle: When the device is subjected to an external impact, the impact force first acts on the large-pore damping mesh 24 and the small-pore damping mesh 25. The large-pore damping mesh 24 can initially block larger objects, while the small-pore damping mesh 25 further filters smaller particles and the impact force. Together, they initially weaken the impact force. Since the rear side of the small-pore damping mesh 25 is slidably connected to the front side of the extrusion plate 26, the impact force will cause the small-pore damping mesh 25 to push the extrusion plate 26 backward. The extrusion block a13, which is fixedly connected to the rear side of the extrusion plate 26, slides inside the support block 12. Inside the sealed chamber 14, when the extrusion block a13 slides backward, it will compress the gas inside the sealed chamber 14. The resistance of the gas will hinder the movement of the extrusion block a13, thereby buffering the impact force on the extrusion plate 26 and achieving a first-level buffering effect. At the same time, the extrusion block b15, which is fixed to the front side of the fixed plate 3, also slides inside the sealed chamber 14; together with the extrusion block a13, they maintain a stable flow of gas inside the sealed chamber 14. The compression plate 26 moves backward, which drives two pairs of transmission plates 8 in the same vertical direction to move. Since the two pairs of transmission plates 8 in the same vertical direction are rotatably connected to two positioning columns 9 respectively, and the positioning columns 9 are fixedly connected to the outside of the limiting rings 10, which are fixedly connected to the compression plate 26, the transmission plates 8 will rotate around the positioning columns 9. The rotation of the transmission plates 8 will drive two moving columns 7 to move. The moving columns 7 are rotatably connected to two pairs of connecting plates 6 in the same vertical direction. The connecting plates 6 are rotatably connected to the limiting columns 5 inside the fixing rings 4 fixed at the four corners of the front side of the fixed plate 3. Therefore, the moving columns 7 will make corresponding movements under the drive of the transmission plates 8. At the same time, the moving blocks 11 fixedly connected to the outside of the moving columns 7 will slide inside the support block 12, which plays a role in guiding and stabilizing the movement of the moving columns 7. Through the linkage of this series of transmission structures, the impact force is dispersed and transformed, further buffering the impact force on the device.

[0028] When the large-hole damping mesh 24 and the small-hole damping mesh 25 are locked onto the fixed plate 22 by multiple locking hooks 23, the positioning rod 20 presses the arc plate 19 to make the rotating block 18 rotate upward around the limiting rod 17. At this time, the positioning rod 20 is self-locked inside the positioning block 16. The arc plate 19 and the limiting plate 21 restrict the horizontal displacement of the positioning rod 20. Thus, the damping mesh is installed on the support frame 1 to buffer and dampen external forces, realizing the rapid installation and disassembly of the damping mesh.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
