Gate groove bottom silt-prevention elastic sill and silt-prevention method

Abstract

The invention discloses a gate groove bottom silt-prevention elastic sill and a silt-prevention method. The gate groove bottom silt-prevention elastic sill comprises sill box, a spring seat and a telescopic plate assembly, wherein one side of the telescopic plate assembly is inclinedly and rotatably fixed to the top part of the sill box; the upper end of the spring seat is fixed to the bottom partof the sill box; the lower end of the spring seat is fixed to the bottom part of a gate groove; and the sill box is higher than a fixed sill on the outer part of the gate groove under the circumstance that the sill box is not stressed by the pressure of a gate. According to the gate groove bottom silt-prevention elastic sill and the silt-prevention method provided by the invention, according to the own operation characteristics of the gate, sills at two ends of the gate groove are made into silt-prevention elastic sills, each silt-prevention elastic sill is formed by the sill box, the springseat and the telescopic plate assembly, the sill boxes are ejected for a certain height when the gate is started to rise, and the telescopic plate assemblies are ejected to form a certain angle with the sill boxes at the same time, so that the bottom silt or gravel is prevented from entering and staying on the sills of the gate groove.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower, and in particular relates to an anti-silting elastic sill at the bottom of a gate groove and an anti-silting method. Background technique [0002] The bottom of the gate groove of the hydraulic structure is silted up or foreign matter such as pebbles enters, which directly affects the normal use of the gate. Since underwater cleaning is very difficult, it is often necessary to hire professional cleaning company divers to clean up, which is time-consuming and laborious, and increases operating costs. How to solve this problem has always been a topic of common concern in the industry. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide an anti-silting elastic sill and anti-silting method at the bottom of the gate groove, which overcomes 1 in the prior art: it is very difficul...
