An automatic rotating anti-clogging bottom grid fence

Abstract

The invention discloses an automatically rotating and anti-clogging bottom grid fence. Along the water flow direction, a plurality of grid bars perpendicular to the water flow direction are arranged at equal intervals on the top of the water inlet of the water intake gallery. Both ends of the grid bars are rotatably installed on the On both sides of the water intake corridor, a water impact drive mechanism is installed on the grid bars, and all the grid bars form a transmission grid driven by the water flow impact drive mechanism to transport the sundries attached to the grid bars to the downstream. In the self-rotating anti-clogging bottom grill provided by the present invention, several grill bars perpendicular to the water flow direction are evenly arranged along the water flow direction, and the water flow impact driving mechanism is used to drive the grill bars to rotate, and the pebbles and other sundries on the bottom grill As the grid bar rotates, it is then transported to the downstream, thereby realizing the automatic sewage discharge of the bottom grid grid and avoiding clogging.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and relates to a bottom grid used in mountainous rivers, in particular to a technology that uses water flow energy to drive the bottom grid to automatically rotate to prevent the bottom grid from being blocked. Background technique [0002] In traditional water conservancy and hydropower projects, the bottom grill dam water intake corridor is used for water intake in mountainous rivers, which includes the bottom grid fence and water intake corridor. Bottom grilles are installed on top of the water intakes of the water intake gallery. The traditional bottom grid fence is to arrange a number of grid bars along the direction of water flow (such as figure 1 (a) shown). In order to prevent debris such as pebbles from being blocked between the grid bars, the grid bars are generally designed to be large at the top and small at the bottom to ensure that the pebbles and other debri...

AI Technical Summary

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.
