Description

Moving guardrail

The present invention relates to a moving guard that is automatically conducted when the river water level rises and automatically stands when the river water level is at the normal water level. More specifically, the hydraulic pressure plate when the buoyancy portion is raised by the water level rise and the railing is conducted. It can be configured to receive water pressure, and can reduce costs by omitting additional components such as weights, and can also prevent damage due to torsional moment of the struts due to weights, and the formation of restoration parts. As a result, the railing can be smoothly raised during normal water level, and it is constructed without depending on the rotation moments of the part where the buoyancy part of the lower part is arranged around the hinge part and the part where the upper handrail is formed. In addition, it can provide convenience in design, and the bearing is formed in the hinge part to smoothly rotate the railing. It relates to a moving guard that can be achieved by the safety action to break them.

In general, railings consisting of holding rods and guardrails are installed in rivers or bridges to prevent falling out of the bridge when a pedestrian or a vehicle travels.

On the other hand, when the water level of the river rises due to the above-mentioned railings, various floats such as tree branches, debris of houses, car damage, etc. are floated from the upstream of the stream to the downstream, and these floats are railings. In addition, the railing is damaged, and this causes the water level to overflow, causing secondary damage.

In order to solve this problem, the applicant has proposed a patent application No. 10-2008-0042691.
