Automatic rotation anti-blocking bottom lattice fence

Abstract

The invention discloses an automatic rotation anti-blocking bottom lattice fence. A plurality of fence strips vertical to the waterflow direction are distributed on the top of a water taking gallery water inlet in the waterflow direction; the two ends of the fence strips are rotationally arranged in the two side wall surfaces of a water taking gallery through bearings; a waterflow impact driving mechanism is arranged on the fence strips; the fence strips form a conveying fence through being driven by the waterflow impact driving mechanism; and sundries attached onto the fence strips are conveyed to a downstream position. The automatic rotation anti-blocking bottom lattice fence provided by the invention has the advantages that the plurality of fence strips vertical to the waterflow direction are uniformly distributed in the waterflow direction; the fence strips are driven to rotate by using the waterflow impact driving mechanism; the sundries such as pebbles positioned on the bottom lattice fence rotate along with the fence strips, and are then conveyed to the downstream position, so that the automatic pollution discharge of the bottom lattice fence is realized; and the blockage isavoided.

Description

Technical field [0001] The invention belongs to the technical field of water conservancy engineering, and relates to a bottom grid fence used in mountain rivers, in particular to a technology that uses water flow energy to drive the bottom grid fence to automatically rotate to prevent the bottom grid fence from being blocked. Background technique [0002] In traditional water conservancy and hydropower projects, the bottom grid fence dam water intake corridor is used for water intake in mountainous rivers, which includes bottom grid fence and water intake corridor. The bottom grid fence is installed on the top of the inlet of the water intake corridor. The traditional bottom grid fence is a fixed arrangement of several fences along the flow direction (such as figure 1 (a) Shown). In order to prevent pebbles and other debris from blocking between the bars, the bars are generally designed to be large and small to ensure that the pebbles and other debris that can pass through the u...

Problems solved by technology

But this kind of traditional bottom grid, there are always pebbles and other sundries of different sizes and shapes that will be stuck on the upper part of the grid, and gradually accumulate more and more, eventually causing the bottom grid to be completely blocked. Therefore, it is necessary to clean the blockage frequently during use, otherwise it will affect the water intake effect

[0003] Therefore, it is necessary to develop a bottom grid that can automatically discharge sewage to prevent it from being blocked by debris such as pebbles and affecting the water intake effect.
