And a wind shield is arranged between the upper end of the first movable plate and the second movable plate, and wind shields are also arranged at the two ends of the first movable plate and the second movable plate.
When the falling object falls to the top of the scheme, the sliding net is firstly bounced, and quickly moves along the upper surfaces of the first movable plate and the second movable plate under the impact of gravity and the falling object, so that the falling object is added with one motion component along the motion track; meanwhile, the spring on the lower side of the movable plate I or the movable plate II absorbs the energy of the falling objects.
The beneficial effect of this scheme can learn according to the statement to above-mentioned scheme, simple structure, and reasonable in design when the thing that drops of eminence falls, unloads the impact force that the power structure can change the thing that falls, has avoided the impact force breakdown top protection of falling thing. The springs are inclined to the vertical plane, so that when the springs are subjected to vertical downward impact force, the impact energy is still conducted downwards and is guided to the side face. The included angle between the spring and the first movable plate and the included angle between the spring and the second movable plate are close to the included angle between the spring and the fixed protective layer, so that the first movable plate and the second movable plate can be supported on the fixed protective layer by the spring without lodging. The tension spring is connected between the first movable plate and the second movable plate, so that the first movable plate or the second movable plate which is only connected with the fixed protective layer through the spring cannot climb on the fixed protective layer, and the tension force of the tension spring prevents the spring from excessively falling, so that the distance between the first movable plate and the second movable plate and the fixed protective layer is ensured, and a stable space structure is formed. The first movable plate, the second movable plate and the spring which connects the first movable plate and the second movable plate with the fixed protective layer form an energy absorption structure, and the energy of falling objects is prevented from being directly applied to the rigid structure. The sliding net on the upper surfaces of the first movable plate and the second movable plate utilizes the sliding net to slide along the first movable plate and the second movable plate to increase the stroke of falling objects in the collision process, thereby reducing the interaction force in the collision, not only making the falling objects difficult to penetrate and protect, but also relatively reducing the damage to the structure; especially, the long strip falling objects with great harm are dragged by the sliding net to fall down. Wheel tracks are arranged at two ends of the upper surfaces of the first movable plate and the second movable plate, and rolling wheels are arranged at two ends of the sliding net, so that the sliding of the sliding net is almost not hindered, and the effect of increasing the stroke of a falling object can be achieved in the instant time. The upper end of the wheel rail is provided with a groove, the roller at the upper end of the sliding net is normally placed in the groove, and the roller can roll out of the groove when encountering vibration. A hinge is arranged between the sliding net and the first movable plate and the second movable plate, so that the sliding net is prevented from falling down, and the sliding net stops sliding continuously when moving to a certain distance. The two ends of the first movable plate and the second movable plate, which are parallel to the wheel rail, are provided with blocking edges which are bent upwards, and the upper ends of the blocking edges are bent inwards, so that the roller wheels of the sliding net cannot be separated from the wheel rail when the sliding net is in vibration. The upper end of the first movable plate stretches out of the upper end of the second movable plate to form a herringbone structure, so that the falling object is prevented from directly penetrating through a gap between the first movable plate and the second movable plate. The slope of the first movable plate and the second movable plate is larger than that of the fixed protective layer, so that once a falling object collides close to the upper end of the first movable plate or the second movable plate, the spring at the upper end is rapidly compressed, and the force unloading structure enables the falling object to move along the plane of the first movable plate or the second movable plate unobvious. The first movable plate, the second movable plate and the fixed protective layer are provided with reinforcing ribs, and two ends of a spring arranged between the first movable plate and the fixed protective layer and between the second movable plate and the fixed protective layer are arranged on the reinforcing ribs, so that the damage to the plate surface is reduced. And a wind shield is arranged between the upper end of the first movable plate and the second movable plate, and wind shields are also arranged at the two ends of the first movable plate and the second movable plate, so that the influence of heavy weather on a steel structure roof with small weight is reduced.
