Embodiment Construction
[0044] The accompanying drawings are schematic diagrams of the implementation of the present invention, so as to facilitate the understanding of the operation principle of the structure. The specific product structure and proportions can be determined according to the use environment and conventional techniques.
[0045] like image 3 As shown, it includes a support column 3, a support arm A6, a support arm B12, a breathing mechanism 15, a cross bar 31, a safety net 33, an opening 37, a floating ball 38, a weft rope 39, a warp rope 41, and a connecting block 50. figure 1 , 2 As shown, the two support columns 3 are vertically fixed in the culvert 1 from the entrance and exit 2 of the culvert 1; figure 1 , 2 As shown in , 3, one end of the safety net 33 with the same width as the entrance and exit 2 of the culvert 1 is installed on the cross bar 31 at the top of the two support columns 3, and the other end of the safety net 33 is installed with a number of uniformly distribut...

The invention belongs to the field of culvert dredging, and in particular relates to a safety protection net, which includes a support column, a support arm A, a support arm B, a breathing mechanism, a cross bar, a safety net, an opening, a floating ball, a weft rope, a warp rope, The connecting block, in which two support columns are vertically fixed inside the hidden culvert from the entrance and exit of the hidden culvert; when the water level in the hidden culvert rises rapidly, the hinge points of the two support arms A and the connecting block on the safety net are pulled by all the floating balls First disconnect, the hinge point of the two support arms B and the connection block on the safety net is disconnected immediately after the disconnection of the hinge point of the support arm A and the connection block, so that the safety net floats on the rising water around the cross bar, without Fast flowing water forms a barrier. When the dredger in the hidden culvert is rushed to the safety net by the rapidly rising water, the drowning person can grasp the safety net to fix the body, and escape quickly from the entrance and exit of the hidden culvert in time.
Description
technical field [0001] The invention belongs to the field of hidden culvert dredging, and in particular relates to a safety protection net. Background technique [0002] Concealed culvert refers to the drainage holes or water passages built under the roadbed and below the road surface in order to make the highway pass through the canal smoothly and not hinder the traffic in the construction of highway engineering. [0003] On April 11, 2019, there was a sudden heavy rain in Shenzhen, and a large amount of rainwater poured into the culvert, swallowing 11 people who were working in the culvert, causing a painful drowning accident in the culvert. [0004] There is often a lot of rubbish washed by rain in the connotation of the water passage. These garbage cannot be cleaned up in time, causing the running water in the confinement to stink. If stinky water is discharged into municipal waterways, it can cause water pollution. Therefore, in order to ensure that the water quality ...
