Abstract

The utility model discloses a water fetching structure, and particularly relates to a river channel water fetching structure. The river channel water fetching structure can be used in regions where debris flow frequently occurs. The river channel water fetching structure comprises a river channel, a water fetching groove, a water diversion structure and gratings. The water fetching groove is formed in the bottom of the river channel and transversely formed along the river channel, the two ends of the water fetching groove respectively stretch to the two sides of the river channel, the water diversion structure is communicated with one end of the water fetching groove, and the gratings cover the top of the water fetching groove. Due to the fact that the gratings are arranged on the water fetching groove, debris flow blocks with the large size can be directly flushed to a downstream position when passing through the water fetching structure, silting can not be caused, and debris flow blocks with the small size can be also conveniently removed even if dropping into the water fetching groove; the water fetching structure is located at the steep and uneven positions of the river channel, and the debris flow can be directly washed away by violent water currents.

Description

River course water intaking structure
Technical field
The utility model relates to a kind of water intaking structure, especially a kind of river course water intaking structure.
Background technology
In power station and diversion works, two kinds of water intaking structural configuration modes are roughly arranged: the one, build barrage Yong Shui in the physical features flat part, build the intake water intaking in the perforate of barrage dam body or both sides, riverbank, barrage upstream, this water-supply method be subject to mud-rock flow affect large (as the deep mountain valleys area, one along the river, the mud-rock flow that occurs of ditch just can become silted up the reservoir before whole barrage to expire); Another is exactly not build barrage, and the direct basis orographic condition is built the water intaking of water intaking building in the both sides, riverbank, and this water intaking structural disadvantages is that water withdrawal is subject to river direction, comes flow effect larger.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of river course water intaking structure that can use at the debris flow activity region.
The utility model solves the river course water intaking structure that its technical problem adopts, comprise river course, also comprise water intaking groove, drawing water structure and grid, described water intaking groove is arranged on river course bottom road lateral arrangement along the river, the two ends of described water intaking groove extend to respectively the two sides in described river course, described drawing water structure is connected with an end of described water intaking groove, and described grid covers the top of described water intaking groove.
Further, described water intaking groove is arranged on Dou Kan position, described river course.
Further, the top of described water intaking groove is mutually concordant with bottom, described river course.
Further, the top of described water intaking groove is higher than bottom, described river course, and the part that exceeds of water intaking groove adopts and builds concrete and make.
Further, described grid adopts stainless steel to make.
The beneficial effects of the utility model are: owing on the water intaking groove, being provided with grid, therefore the mud-rock flow block process that volume is larger will directly rush at downstream while fetching water structure, can not cause alluvial, even the mud-rock flow block of small volume falls into water intaking, groove also is convenient to cleaning; The addressing of water intaking structure is in Zhong Doukan position, river course, and comparatively fierce current just can directly wash away mud-rock flow; In addition, what the water intaking structure adopted is the mode of full riverbed Yokogawa to layout water intaking groove, and the whole current in riverbed are all by middle water intaking groove overhead stream mistake, and water withdrawal also is guaranteed with regard to corresponding; Finally, because water intaking structure Main Basis natural terrain, geological conditions form, the building quantity relatively economical.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is a kind of schematic diagram of embodiment;
Fig. 3 is the schematic diagram of another kind of embodiment;
Component, position and numbering in figure: river course 1, water intaking groove 2, drawing water structure 3, grid 4, bottom, river course 5, the water surface 6.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises river course 1, also comprise water intaking groove 2, drawing water structure 3 and grid 4, described water intaking groove 2 is arranged on river course bottom 5 road 1 lateral arrangement along the river, the two ends of described water intaking groove 2 extend to respectively the two sides in described river course 1, described drawing water structure 3 is connected with an end of described water intaking groove 2, and described grid 4 covers the top of described water intaking groove 2.When construction, choose the position that river course 1 is suitable, generally be chosen at the upstream at the Dou Kan position in river course 1, as shown in Figures 2 and 3, current are more anxious herein, easily the foreign material such as mud-rock flow washed away.Then 5 construction water intaking grooves 2 in river course bottom, it is horizontal that water intaking groove 2 connects whole river courses 1, and then the top at water intaking groove 2 is that opening part installs grid 4, and described grid 4 can adopt common iron, stainless steel, macromolecular material or composite material to make.Then be communicated with drawing water structure 3 at an end of water intaking groove 2, drawing water structure 3 can be pipeline or ditch.When current flow through from water intaking groove 2 tops, owing in grid 4, leaving hole, current just flow in water intaking groove 2, and then automatic stream drawing water structure 3; When mud-rock flow occurs, the mud-rock flow block of bulk can't retain and just rush at downstream at the Dou Kan position, even the mud-rock flow of fritter enters into water intaking groove 2, also easy cleaning through grid 4; In addition, due to water intaking groove 2 Yokogawas, to being arranged on whole river course 1, the whole current in river course 1 are all by middle water intaking groove 2 overhead stream mistakes, and the water withdrawal of whole water intaking structure is just comparatively stable.
As wherein a kind of embodiment of the present utility model, as shown in Figure 2, the top of described water intaking groove 2 is mutually concordant with bottom 5, described river course.This mode can directly select the rock excavation of bottom, river course 5 to become water intaking groove 2, has so just saved extra material.
As another kind of embodiment of the present utility model, as shown in Figure 3, the top of described water intaking groove 2 is higher than bottom, described river course 5, and the part that exceeds of water intaking groove 2 adopts and builds concrete and make.This mode adopts half excavation, partly builds concrete construction water intaking groove 2, and this mode can reduce the dependence to landform, but needs extra material.
