Abstract
The invention discloses a sand blocking and water taking gate for hydraulic engineering. The sand blocking and water taking gate comprises a gate and rubber water-stop strips. The rubber water-stop strips are respectively arranged at the left side edge and the right side edge of an upstream side of the gate and are in seal slide fit with gate slots; at least two convex reverse sliders are respectively vertically arranged along the edges of the left side edge and the right side edge of the upstream side of the gate at intervals, and at least two main sliders are respectively vertically arranged along the edges of the left side edge and the right side edge of a downstream side of the gate; the top of the gate is of an arc-shaped overflow plate structure, and a plurality of water breaking plates are transversely arranged on an upper plate surface of an arc-shaped overflow plate at intervals along the gate; the water breaking plates comprise inclined plates and upright plates, the inclined plates are inclined towards the downstream side of the gate, and the upright plates are perpendicularly fixedly connected to lower plate surfaces of the inclined plates; the lower edges of the inclined plates are tangential to the upper plate surface of the arc-shaped overflow plate. The sand blocking and water taking gate has the advantages that the service lives of a pump station and a hydraulic turbine set can be effectively prolonged, and the gate is simple in structure and convenient to operate and maintain.
Description
Technical field
The present invention relates to hydraulic engineering gate, especially relate to hydraulic engineering sand-trap water-take gate.
Background technology
Strengthen the weak link construction such as irrigation and water conservancy along with the emphasis of investment on water conservancy progressively turns to, accelerate water resource infrastructure construction comprehensively and come up, for solving emphatically the problem such as irrigation and water conservancy and countryside potable water security, built a collection of big-and-middle-sized irrigation and drainage pumping plant.Known according to pump working mechanism, in water, sediment concentration is higher, particle is larger, and water pump lift also reduction is larger, and silt is also more serious to the abrasion of water pump vane, and the normal service life of water pump is shortened dramatically.In view of the foregoing, reducing sediment charge in water is effective solution route, how effectively to reduce diversion sediment charge and becomes the technological difficulties that need solution.
Summary of the invention
The object of the invention is to provide a kind of hydraulic engineering sand-trap water-take gate.
For achieving the above object, the present invention takes following technical proposals:
Hydraulic engineering of the present invention sand-trap water-take gate, comprises a body, is separately positioned on the left and right side of described door body upstream side for sealing with gate slot the rubber water-proof bar being slidably matched; Edge along the left and right side of door body upstream side is arranged at intervals with respectively at least two anti-slide blocks of convex up and down, is arranged at intervals with up and down respectively at least two master sliders along the edge of the left and right side in door body downstream; The top of door body is arc overflow plate structure, at described arc overflow plate upper face along door body multiple one's water breaks plates that have been horizontally arranged at interval; Described one's water breaks plate forms with the vertical riser that is connected in its lower face by rolling downstream oblique swash plate; The upper face of the lower edge of described swash plate and arc overflow plate is tangent.
The invention has the advantages that and realize the application life of effectively improving pumping plant, water wheels unit, simultaneously gate structure simple, easy to operate, be convenient to safeguard.The present invention can be widely used in the position such as Forebay of Pumping Station intake, water channeling type power station pressure intake, comes when the water yield is large gate to fall, and carrys out the water yield hour gate is mentioned, and has guaranteed that Forebay of Pumping Station can guide to the clear water that sediment charge is less.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is working state schematic representation of the present invention.
The specific embodiment
As shown in Figure 1, 2, 3, hydraulic engineering of the present invention sand-trap water-take gate, comprises a body 1, is separately positioned on the left and right side of described door body 1 upstream side for sealing with gate slot 2 the rubber water-proof bar 3 that the cross section being slidably matched is P shape structure; Edge along the left and right side of door body 1 upstream side is arranged at intervals with respectively two anti-slide blocks 4 of convex up and down, is arranged at intervals with up and down respectively two master sliders 5 along the edge of the door body 1 left and right side in downstream; The top of door body 1 is arc overflow plate 6 structures, at described arc overflow plate 6 upper faces along door body 1 multiple one's water breaks plates that have been horizontally arranged at interval; Described one's water breaks plate forms with the vertical riser 8 that is connected in its lower face by rolling downstream oblique swash plate 7; The upper face of the lower edge of described swash plate 7 and arc overflow plate 6 is tangent.
Operating principle of the present invention is summarized as follows:
Being arranged on the left and right side upper section of a body 1 upstream side is the rubber water-proof bar 3 of P shape structure, can well retain like this silt, in order to avoid silt enters in gate slot 2; Arc overflow plate 6 structures are arranged at door body 1 top, and at arc overflow plate 6 upper faces along door body 1 multiple one's water breaks plates that have been horizontally arranged at interval, the effect of one's water breaks plate is to avoid current to form behind the door negative pressure from gate top overflow time gating, produce cavitation erosion, cause gate vibration, one's water breaks device can separate current, carries out fully tonifying Qi, effectively reduces negative pressure after gate.In the time that flood season, the water yield was large, carry silt more, current run into gate obstruction formation chokes water, and most of sedimentation is before gate, and clear water enters diversion forebay from gate top by overflow, plays the mixed effect of getting clearly of blocking; The water yield hour at ordinary times, sediment charge is less, for guaranteeing diversion flow, gate can be proposed to aperture, allows water flow directly into forebay.
