Embodiment Construction
[0044] The accompanying drawings are all schematic diagrams of the implementation of the present invention, so as to understand the principle of structural operation. The specific product structure and proportional size can be determined according to the use environment and conventional technology.
[0045] like image 3 As shown, it comprises support column 3, support arm A6, support arm B12, breathing mechanism 15, cross bar 31, safety net 33, opening 37, float 38, weft rope 39, warp rope 41, connection block 50, wherein as figure 1 , 2 As shown, two support columns 3 are vertically fixed in the hidden culvert 1 from the outside of the entrance 2 of the hidden culvert 1; figure 1 , 2 , 3, one end of the safety net 33 with the same width as the entrance and exit 2 of the hidden culvert 1 is installed on the crossbar 31 at the top of the two support columns 3, and the other end of the safety net 33 is equipped with a number of holes that are evenly distributed along the wid...

The invention belongs to the field of buried culvert desilting, and particularly relates to a safety protection net which comprises supporting columns, supporting arms A, supporting arms B, a breathing mechanism, a cross rod, a safety net, an opening, floating balls, a weft rope, a warp rope and a connecting block, wherein the two supporting columns are vertically fixed in a buried culvert from the outside of a buried culvert inlet / outlet. When the water surface in the buried culvert rapidly rises, the hinge points of the two supporting arms A and the connecting blocks on the safety net are firstly disconnected under the pulling of all the floating balls, and the hinge points of the two supporting arms B and the connecting blocks on the safety net are disconnected along with the disconnection of the hinge points of the supporting arms A and the connecting blocks, so that the safety net floats on the rising water surface around the cross rod, and does not block flowing water which flows quickly. When a desilting person in the buried culvert is flushed to the safety net by flowing water rising rapidly, a drowning person can grasp the safety net to fix the body and rapidly escape from the buried culvert inlet / outlet in time.
Description
technical field [0001] The invention belongs to the field of hidden dredging, and in particular relates to a safety protection net. Background technique [0002] Implied culverts refer to the drainage channels or water passages built under the road surface under the roadbed in order to make the road pass through the canal smoothly without hindering traffic in the construction of highway projects. [0003] On April 11, 2019, a heavy rain fell in Shenzhen City, and a large amount of rainwater poured into the culvert, swallowing 11 people who were working in the culvert, causing a tragic drowning accident in the culvert. [0004] There are often a lot of garbage washed by rainwater floating in the underpass as a water passage. These garbage cannot be cleaned up in time, causing the running water in the underside to stink. If the smelly water is discharged into municipal waterways, it will cause water pollution. Therefore, in order to ensure that the water quality in the culve...
