Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a flood protection device for hydraulic bridges, which solves the problem that traditional bridge pier protection equipment cannot buffer floating objects when floods occur, and floating objects and stones cause corrosive damage to bridge piers. It is not conducive to the subsequent durable use of the bridge pier, and the traditional protective equipment cannot distribute the side with the fast flow rate to the other side, so the pier is unevenly impacted, resulting in serious damage to the pier

Abstract

The invention provides a water conservancy bridge flood-fighting protection device which comprises a mounting hoop, the back face of the mounting hoop is in threaded connection with a mounting bolt, the position, close to the front face, of the top of the mounting hoop is fixedly connected with a material shaking limiting mechanism, the two sides of the material shaking limiting mechanism are each provided with a protection baffle through a transmission connecting rod, floating buffer mechanisms are uniformly and rotatably connected with the surfaces of the tops of the protection baffles, an adjusting guide mechanism is fixedly connected with the middle of the interior of each protection baffle, one end of each transmission connecting rod is rotatably connected with the interior of the corresponding adjusting guide mechanism, and limiting sliding rods are symmetrically and fixedly connected with the positions, close to the front faces, of the inner sides of the protection baffles. The invention relates to the technical field of water conservancy. According to the water conservancy bridge flood-fighting protection device, the impact force of flood can be buffered through contact resistance, and damage caused by the flood to the protection device is avoided.

Description

technical field [0001] The invention relates to the technical field of water conservancy, in particular to a flood protection device for a water conservancy bridge. Background technique [0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. Also known as water engineering. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources. [0003] Such as Chinese Invention Publication No.: CN112343010A, a bridge pier anti-collision protection device, comprising a bridge pier, on which an annular support is fixed, the outer surface of the support is circular, and an annular groove is provided on...
