[0002] With the development of the construction industry, there are more and more people working in the construction industry. The safety management of the construction site is very difficult. If the safety protection facilities on the construction site are not in place and the safety protection management measures are not perfect, accidents are likely to occur. Doing a good job in safety protection is of vital importance to ensuring the safety of the lives of on-site construction workers.

[0003] After searching, Chinese utility model patent CN218324032U discloses a safety protection device for construction sites, which clamps the protection net between two fixed columns by setting a clamping structure. Its background technology points out that there are many kinds of construction safety protection nets on the market, but these safety protection nets generally cannot be conveniently stored, and the construction site still lacks a lot of construction tools and some safety protection devices, which leads to personal injuries caused by people being hit or falling into public pits of buildings on the construction site, greatly reducing the practical performance of the protection device, and failing to block people and protect against falling objects from high altitudes. When an accident occurs, firefighting and security need to continue to add protection devices when they arrive at the scene, which will cause a waste of time. Therefore, a safety protection device for construction sites is proposed to solve the above problems. Summary of the invention

[0030] 2) Then start the two first electric telescopic rods 8 and set the baffle 10 at a suitable position to block the falling objects;

[0031] 3) Start the two motors 4 and the two second electric telescopic rods 302;

[0032] 4) Finally, the two moving blocks 303 are closed, and the two protection nets 6 are unfolded to block the pedestrians passing by.

[0033] In summary, the construction site safety protection device, by setting the adjustment structure 3, when the construction is carried out, the protection device is arranged in a suitable position, and then when the staff passes by, the two second electric telescopic rods 302 are retracted, the two sets of second connecting rods 305 move toward the two sets of first connecting rods 304, the two sets of first connecting rods 304 move toward the two fixed columns 2, and the two clamping rods 307 are away from the two sets of springs 308 to allow the staff to pass through. After the person passes, the two second electric telescopic rods 302 extend to close the two moving blocks 303 together, and the two clamping rods 307 and The two groups of latch teeth 309 are engaged with each other to complete the adjustment function of the protective device. The construction site safety protection device is constructed by setting a motor 4. When a worker wants to pass through the protective device, the two moving blocks 303 move toward the two fixed columns 2. At the same time, the two motors 4 are started to drive the two rotating shafts 5 to rotate and retract the two protective nets 6. After the worker passes, driven by the two second electric telescopic rods 302, the two moving blocks 303 are closed and the two protective nets 6 are unfolded to block passers-by, thereby completing the protection function of the construction site.
