In the process of rotating the protective mesh plate 2 on the right side to unfold, the upper hinge 41 fixedly connected is driven to rotate synchronously. When the upper hinge 41 rotates, it drives the fixedly connected active gear 40 to rotate synchronously, so that the active gear 40 drives the third transmission gear 39 to rotate, and the third transmission gear 39 rotates to drive the fixedly connected second bevel gear 38 to rotate synchronously. The second bevel gear 38 rotates to drive the first bevel gear 37 and the second transmission gear 36 to rotate synchronously, so that the first transmission gear 35 meshing with the second transmission gear 36 rotates, so that the first transmission gear 35 drives the driven gear 34, and then the blocking net 31 fixedly connected to the driven gear 34 is flipped outward to the unfolded state, and when the protective structure is folded as a whole, the protective mesh plate 2 on the right side is rotated in the opposite direction. At this time, the other components also rotate in the opposite direction synchronously, so that the blocking net 31 is turned toward the protective net plate 2 to the retracted state, so as to facilitate the storage and transportation of the protective structure as a whole. Through the structural design of the blocking component, the function of blocking the broken stones, broken cement blocks and broken bricks falling from the high altitude is realized, which solves the problem that the splashing of cement fragments or broken bricks will inevitably be generated when some building components are broken during the construction process, and the flying direction of the splashing broken bricks cannot be controlled, and the falling from the high altitude is very likely to cause harm to the construction workers on the ground, thereby improving the safety factor of the construction workers on the ground and reducing the probability of accidents at the construction site. At the same time, the function of folding the protective structure as a whole is also realized. When folding, the blocking net 31 can be automatically retracted, and when unfolding, the blocking net 31 can be automatically unfolded. The foldable structural design can conveniently transport the protective structure as a whole, and the linkage opening and closing of the blocking net 31 facilitates the installation of the protective structure as a whole. ;

[0022] Furthermore, the guide assembly includes an outlet 43, which is opened at a position near the bottom of the protective mesh plate 2, and a baffle 44 is arranged on the rear side of the protective mesh plate 2. Both sides of the top of the baffle plate 44 are fixedly connected with a rotating shaft 45, and the rotating shaft 45 is rotatably connected to the protective mesh plate 2, and a torsion spring 46 is sleeved on the outer side of the rotating shaft 45, and the side of the torsion spring 46 close to the protective mesh plate 2 is fixedly connected to the protective mesh plate 2, and the side of the torsion spring 46 away from the protective mesh plate 2 is fixedly connected to the baffle 44, and a guide plate 47 is fixedly connected at the eaves position of the bottom of the outlet 43 on the rear side of the protective mesh plate 2, and the guide plate 47 is designed in an inclined shape, and the guide plate 47 is made of engineering plastic. When working, the debris or other debris splashed down is collected by the blocking net 31, and after the debris falls on the blocking net 31, the debris rolls along the blocking net 31 to the outlet 43 until it hits the baffle 44, and under the action of the impact force, the baffle 44 rotates with the rotating shaft 45 The axis rotates, thereby opening the discharge port 43, allowing the crushed stones to fall onto the guide plate 47 through the discharge port 43, and the crushed stones are guided by the guide plate 47 to fall into the interior of the building, thereby preventing the crushed stones from falling from a high altitude and causing harm to the construction workers on the ground. When the baffle plate 44 turns over with the rotating shaft 45 as the axis, it drives the fixedly connected torsion spring 46 to twist synchronously, generating elastic deformation. After the crushed stones pass through the rear baffle plate 44, it rotates in the opposite direction to its original position under the action of the restoring force of the torsion spring 46, so that only the crushed stones falling from the outside can pass through the discharge port 43, effectively preventing the crushed stones inside from splashing to the outside of the building through the discharge port 43. Through the structural design of the guide component, the function of harmlessly treating the crushed stones, broken cement blocks and broken bricks collected by the blocking component is realized, so that the collected crushed stones, broken cement blocks and broken bricks fall into the interior of the building along the guide component, thereby preventing the crushed stones, broken cement blocks and broken bricks from accumulating on the blocking component, causing the blocking component to bear too much load.

[0023] Furthermore, the buffer assembly includes a first buffer module and a second buffer module, the first buffer module is arranged on a side of the bottom end of the blocking net 31 close to the support column 1, and the second buffer module is arranged on a side of the bottom end of the blocking net 31 away from the support column 1, the first buffer module includes a movable groove 48, the movable groove 48 is opened on the support column 1, and the inside of the movable groove 48 is fixedly connected to a guide rod 49, the outer side of the guide rod 49 is wound with a first spring 50, and the outer side of the guide rod 49 is also sleeved with a movable plate 51, the top end of the movable plate 51 is fixedly connected to a first buffer seat 52, the top end of the first buffer seat 52 is rotatably connected to a first roller 53, and the top end of the first roller 53 abuts against the bottom end of the blocking net 31, The top end of the first spring 50 is fixedly connected to the bottom end of the movable plate 51, and the bottom end of the first spring 50 is fixedly connected to the bottom of the inner wall of the movable groove 48; during operation, when the blocking net 31 is impacted by falling objects, the blocking net 31 rotates downward under the action of the impact force, and squeezes the first roller 53 and the first buffer seat 52 arranged at the bottom end of the blocking net 31, so that the first roller 53 and the first buffer seat 52 move downward under the action of the squeezing force, and drive the fixedly connected movable plate 51 to move downward synchronously, so that the movable plate 51 squeezes the first spring 50, and the impact force exerted on the blocking net 31 is absorbed by the first spring 50, so as to avoid the blocking net 31 being damaged due to excessive impact force exerted on it at one time.

[0024] Furthermore, the second buffer module includes a second roller 54, which is rotatably connected to the inside of the second buffer seat 55, one side of the second buffer seat 55 is slidably connected to the connecting seat 56, the connecting seat 56 is fixedly connected to the front of the protective net plate 2, the bottom end of the second buffer seat 55 abuts against the buffer block 57, the rear side of the buffer block 57 is fixedly connected to the front end of the second spring 61, the rear side of the second spring 61 is fixedly connected to the supporting plate 60, and the rear side of the supporting plate 60 is fixedly connected to the front of the protective net plate 2; during operation, when the blocking net 31 is impacted by falling objects, the second roller 54 and the second buffer seat 55 arranged at the bottom of the blocking net 31 are squeezed at the same time, so that the second roller 54 and the second buffer seat 55 move downward The second roller 54 and the second buffer seat 55 generate friction with the inclined surface on the buffer block 57 during the downward movement, and the impact force is consumed by the friction force. At the same time, the buffer block 57 is also squeezed by the second buffer seat 55 to move toward the supporting plate 60, and squeezes the second spring 61, so that the second spring 61 produces elastic deformation to absorb the impact force. After the impact force disappears, the second spring 61 pushes the buffer block 57 to return to its original position, and the blocking net 31 is pushed to return to its original position synchronously through the second roller 54 and the second buffer seat 55. At the same time, in this process, the upward rebound of the blocking net 31 can give the falling objects blocked on the blocking net 31 kinetic energy of movement, so that the falling objects can smoothly knock open the baffle 44 and pass through the discharge port 43.

[0025] Furthermore, a slope is provided at the front end of the buffer block 57, and a sliding groove 58 is provided at the bottom of the buffer block 57. A sliding block 59 is slidably connected inside the sliding groove 58. The sliding block 59 is fixedly connected to a supporting plate 60, and the supporting plate 60 is in an "L" shape. During operation, when the buffer block 57 moves, the sliding block 59 fixedly connected to the supporting plate 60 slides synchronously inside the sliding groove 58. The combined action of the sliding groove 58 and the sliding block 59 plays a role in guiding and limiting the movement of the buffer block 57, thereby preventing the buffer block 57 from excessively moving under the action of the restoring force of the second spring 61.
