[0025] This detailed implementation manner is a safety protection device, and its structural schematic diagram is as Figures 1 to 4As shown in the figure, it includes a main installation cylinder 1. An adjustment and installation mechanism 2 is installed inside the main installation cylinder 1 and on one side above it. The adjustment and installation mechanism 2 includes a rotating rod 211, a side installation frame 214, and a hand crank frame 216. A blocking protection net 3 is wound around the periphery of the rotating rod 211. The end of the blocking protection net 3 is connected to a secondary installation cylinder 4. A disassembly and assembly mechanism 5 is installed inside the secondary installation cylinder 4 and at the end of the blocking protection net 3. Reflective stickers 6 are attached to the peripheries of the main installation cylinder 1 and the secondary installation cylinder 4. The adjustment and installation mechanism 2 includes a winding adjustment component 21, and the winding adjustment component 21 is installed inside the main installation cylinder 1. The winding adjustment component 21 includes a rotating rod 211, and the rotating rod 211 is installed inside the main installation cylinder 1. A first bevel gear 212 is fixed to the periphery of one end of the rotating rod 211, and a second bevel gear 213 is engaged with one side of the first bevel gear 212. A side installation frame 214 is fixedly provided on one side above the main installation cylinder 1. A transmission rod 215 is jointly provided in the middle of the second bevel gear 213 and the side installation frame 214, and a hand crank frame 216 is fixed to the periphery of the transmission rod 215. A locking component 22 is jointly installed on one side of the side installation frame 214 and in the middle of the hand crank frame 216. The locking component 22 includes a locking screw groove 221, and the locking screw groove 221 is distributed and opened on the outer side of the side installation frame 214. A slot 222 is opened in the middle of the hand crank frame 216. A locking bolt rod 223 passes through the middle of the locking screw groove 221 and the slot 222. The locking screw groove 221 is distributed in a circular form and equidistantly along the outer side of the side installation frame 214. The staff can first position and install the main installation cylinder 1 at a point on the periphery of the safety project. Then, they can hold the other secondary installation cylinder 4 and move it to the next point in the interception area. At this time, the blocking protection net 3 connected by the disassembly and assembly mechanism 5 inside the secondary installation cylinder 4 will be pulled out. Since the blocking protection net 3 is wound around the periphery of the rotating rod 211, the effect of extending and stretching the blocking protection net 3 can be achieved in this state, and the interception length of the blocking protection net 3 can be freely selected. It is convenient for collection and installation. Subsequently, the staff can also position and install the secondary installation cylinder 4 at the second point. The staff can shake the hand crank frame 216 in the winding direction of the blocking protection net 3. At this moment, driven by the transmission rod 215 connected to the hand crank frame 216, the second bevel gear 213 will drive the first bevel gear 212 and the rotating rod 211 to reverse-tighten the blocking protection net 3, reducing the looseness of the blocking protection net 3. Subsequently, the staff can align and insert the locking bolt rod 223 into the slot 222 opened in the middle of the position where the hand crank frame 216 is located, and then thread it into the corresponding locking screw groove 221 in the distributed state on the outer side of the side installation frame 214, thus avoiding the loosening threat of the blocking protection net 3 in subsequent operations and improving safety protection.

[0027] Working principle: The staff can first position and install the main installation cylinder 1 at a point outside the safety project, and then hold another auxiliary installation cylinder 4 and move it to the next point in the interception area. At this time, the interception protection net 3 connected by the disassembly and assembly mechanism 5 inside the auxiliary installation cylinder 4 will be pulled out. Since the interception protection net 3 is wound around the periphery of the rotating rod 211, the effect of extending and stretching the interception protection net 3 can be achieved in this state, and the interception length of the interception protection net 3 can be freely selected, which is convenient for collection and installation. Subsequently, the staff can also position and install the auxiliary installation cylinder 4 at the second point. The staff can turn the hand crank 216 in the winding direction of the interception protection net 3. At this moment, driven by the transmission rod 215 connected to the hand crank 216, the second bevel gear 213 will drive the first bevel gear 212 and the rotating rod 211 to pull the interception protection net 3 in the reverse direction to reduce the looseness of the interception protection net 3. Subsequently, the staff can insert the locking bolt rod 223 into the slot 222 opened in the middle of the position where the hand crank 216 is located and screw it into the corresponding locking screw groove 221 distributed on the outside of the side installation frame 214, so as to avoid the loosening threat of the interception protection net 3 in subsequent operations and improve safety protection. When it is necessary to evacuate and carry the safety protection guardrail later, personnel can use the hanging groove holes 54 provided on the connecting belt 53 at the end of the interception protection net 3 to take the hanging groove holes 54 out of the hooks 52 provided inside the auxiliary installation cylinder 4, and then manually turn the hand crank 216 to wind the interception protection net 3 into the main installation cylinder 1, which greatly solves the problem of occupying space and provides convenience for personnel to carry.
