Description

Be used for hydraulic engineering dykes and dams anticollision early warning structure

Technical Field

The invention relates to the technical field of hydraulic engineering, in particular to a dam anti-collision early warning structure for the hydraulic engineering.

Background

Hydraulic engineering is a general term for various engineering constructions built for controlling, utilizing and protecting water resources and environments on the earth surface and underground. The existing hydraulic engineering dam mainly comprises an earth-rock dam and a concrete dam, and the dam plays a great role in the renovation of the hydraulic engineering, so that the dam has certain requirements on the service life of the dam.

At present, in order to reduce the damage caused when ships strike the dam, a collision prevention piece is often arranged on one side of the dam. The anticollision piece usually consists of an anticollision spring and an anticollision plate, one end of the anticollision spring is connected with the dam, and the anticollision plate is installed at the other end of the anticollision spring. Since the water level in the dam is not always a stable height, especially the water level is different between the flood tide and the tide, if the bumper is fixedly installed on the side of the dam, the installation area of the bumper is large, and the cost is high. The conventional solution is that a vertical anti-collision chute is arranged on a dam, an anti-collision piece is slidably mounted on the anti-collision chute, and a floating block is mounted on the bottom surface of the anti-collision piece, so that the height of the anti-collision piece can be adjusted along with the rise and fall of the water level.

According to the related art, the inventor believes that the existing bumper is usually slidably mounted in the chute, and the dam is usually inclined, so that when the bumper floats, the force applied to the bumper is vertically upward, so that the bumper can be too tightly attached to the chute when sliding along the chute, and the friction between the bumper and the chute is large, the abrasion speed of the chute is increased, and frequent maintenance is required.
