Abstract
The utility model belongs to a hydraulic engineering draining and sand flushing control device, in particular relating to a self-maintaining weir culvert, comprising overflow weirs which are built on a natural river bed, wherein, self-maintaining draining device units are uniformly distributed on the river bed; a self-maintaining draining device of each unit is formed by arrangement of an overflow weir on a foundation plate; a water retaining cavity the surface of which is provided with a sloping surface and the end part of which is opened is arranged on the foundation plate on the rear of the overflow weir; an initiative turnover plate the lower part of which is laid particular stress is fixedly connected to the opening end of the water retaining cavity through rotating shafts which are respectively arranged on two sidewalls; the initiative turnover is matched with an opening which is formed by the two sidewalls; draining and sand flushing bottom holes are respectively arranged under the foundation plate on both sides of the initiative turnover plate; and draining and sand flushing flashboards are arranged on the draining and sand flushing bottom holes by means of matching and respectively fixed with the rotating shafts of the initiative turnover plate. The hydraulic engineering draining and sand flushing control device can automatically control the opening and closing of the draining and sand flushing flashboards of the draining and sand flushing bottom holes according to water flow of a river channel, and guarantees that fronts of the weirs are not filled up with sediment.
Description
Technical field
The utility model belongs to hydraulic engineering sluicing sand surfing control device, especially for containing towards the silt weir certainly of river course.
Background technology
The river, Xinjiang belongs to flashy stream more, and winter is very long, cold, and sand content is big, and the thickness inequality, and annual runoff is very big with seasonal variations.The overflow weir ubiquity silt alluvial problem of building on the river course, alluvial is the common fault of all overfalls before the weir.
Summary of the invention
The purpose of this utility model is to provide a kind of can control the opening and closing of the flood discharge sand surfing flashboard of flood discharge flushing sluice according to the size variation of river discharge automatically from containing towards the silt weir, guarantees not deposited by silt before the weir.
The utility model is achieved in that a kind of from containing towards the silt weir, be included in the overflow weir of building on the natural stream channel, the uniform setting on the riverbed certainly towards silt water draw-off unit, each unit certainly towards the silt water draw-off for overflow weir is being set on foundation slab, the surface is being set on the foundation slab of overflow weir back to have domatic, its open-ended dash chamber, the rotating shaft that is provided with respectively on by the two side at dash chamber openend affixed the bottom active turnover panel of laying particular stress on, initiatively turnover panel matches with the opening that the two side constitutes, flood discharge sand surfing bottom outlet is being set respectively below its both sides foundation slab, cooperate flood discharge sand surfing flashboard is installed on flood discharge sand surfing bottom outlet, the both sides of flood discharge sand surfing flashboard are fixed together with the rotating shaft of active turnover panel respectively.
When natural streamflow amount hour, flood discharge sand surfing bottom outlet is closed, the overflow head on weirs is also less, current climb over from weir crest, form the water surface.When natural streamflow amount was big, the overflow head on weirs was more, and it is big to cross the weir flow amount, and current strengthen the impact force of active turnover panel, and initiatively turnover panel rotates and opens under flow action.Because coaxial being connected of flood discharge sand surfing flashboard of installing on the flood discharge sand surfing bottom outlet of the affixed rotating shaft in turnover panel both sides and its both sides initiatively, thereby drive the flood discharge sand surfing flashboard unlatching of both sides flood discharge sand surfing bottom outlet.When the active turnover panel was all opened, the flood discharge sand surfing flashboard of both sides was all opened, and flood drives the preceding silt of flood discharge sand surfing flashboard by letting out the downstream, river course under the flood discharge sand surfing bottom outlet.When natural streamflow quantitative change hour, the water flow impact pressure that impacts on the main turnover panel constantly reduces, and initiatively turnover panel is got back to original position by laying particular stress on of self, drives the coaxial flood discharge sand surfing flashboard in both sides simultaneously and gets back to original position, up to the gate Close All.The utility model can guarantee not deposited by silt before the weir according to the size opening and closing of the flood discharge sand surfing flashboard of control flood discharge sand surfing bottom outlet automatically of streamflow amount.
The utility model is described in further detail below in conjunction with accompanying drawing.
