Abstract
The utility model relates to an arch-shaped clapboard for an ecological fishway, which is characterized in that: a fish passing notch is arranged at the upper part of the clapboard, a flow passing hole is arranged in the lower part of the clapboard, and sand passing holes are arranged in the two ends at the bottom of the clapboard. Compared with the prior art, the clapboard has the advantages of low cost, strong fish passing capacity, capability of realizing automatic sludge cleaning and the like.
Description
Technical field
The utility model relates to a kind of fish pass dividing plate, especially relates to a kind of ecological fish pass arch dividing plate.
Background technology
Fish are the owners in nature rivers and creeks, and the life condition of fish is because human factor has become quite fragile.Fish pass is that gate dam or natural obstacle place are a kind of fish pass structure that fish migration is built, and is a kind of ecological measure of protecting natural fishery resources, reaching bio-diversity and sustainable development.In river all over the world, people have erected hydraulic structures such as many check dams, sluice in order to control flood or to set up the power station.Meanwhile, also brought the existence problem of fish, because most of fish all have the habit of the migration of in rivers, migrating.Therefore, in China's large-scale building of water conservancy projects building today, construction fish pass, research fish pass become one of important water conservancy hot issue.Successful fish pass can provide strong assurance through the barrage hydraulic structure smoothly for fish, can remedy the ecology influence of barrage building to river migration migratory fishes, realizes the construction theory of ecological water conservancy, harmonious water conservancy.
The construction of water resource engineering certainly will increase the weight of the deterioration of China's stock of fish living environment; In coordinating water resources development and protection of fish resources contradiction; Fish pass construction a kind of engineering measure of alleviating or addressing this problem of can yet be regarded as; Particularly because technological progress, the appearance of some more effective ecological fish pass is for fish pass widely-used opened up new space.Denier formula fish pass is divided into many steps by the flat board that the V-type notch is set with tank for wherein to use one of more fish pass form, and its tangible advantage is; Effect of energy dissipation is good; The fish pass volume is less, and fish can pass through in any depth of water, and approach is not crooked, surface current speed is big; Help fish pass import attracting, the fish pass utilization rate is high.Simultaneously, present Denier formula fish pass, some deficiency below existing:
1) the slabbed construction stress performance is not good, is prone to produce the crack, influences structure durability and service life;
2) flow turbulence is violent in the fish pass, and flow velocity is excessive;
3) gas saturation is too high, influences the existence of fish in fish pass;
4) the fish pass bottom is prone to produce silting, influences the fish pass water environment.
For overcoming above defective, be badly in need of new ecological fish pass form of structure, and do not find the report of relevant ecological fish pass arch dividing plate as yet at present.
The utility model content
The purpose of the utility model is exactly to provide a kind of cost low for the defective that overcomes above-mentioned prior art existence, and it is strong to cross the fish ability, can realize the ecological fish pass arch dividing plate of automatic desilting.
The purpose of the utility model can realize through following technical scheme: a kind of ecological fish pass arch dividing plate, it is characterized in that described dividing plate is an arch, and this dividing plate top was provided with the fish notch, and the bottom is provided with flowing hole, and the two ends, bottom were provided with husky hole.
Described dividing plate arch rise ratio is 0.15～0.35.
Described fish width of rebate excessively is 0.25～0.45 of a spacer width, highly is 0.4～0.7 of dividing plate height.
The described fish notch shape of crossing is rectangle, trapezoidal, U type or V-type.
Described flowing hole is circular, and number is 1～7, is evenly arranged in the lower partition, and the described flowing hole gross area was 0.05～0.15 of a fish notch.
Extreme higher position, described flowing hole center was lower than fish notch bottom.
The husky hole of described mistake is positioned at two corners, dividing plate bottom, and for circular-arc, the area in the husky hole of single mistake was 1%～5% of a fish notch area.
Compared with prior art, the utlity model has following advantage:
1) ecological fish pass arch dividing plate adopts the domes form, has optimized the bearing mode of structure, and construction material significantly reduces, and financial cost obviously descends.
2) cross the fish notch with flowing hole current jacking and fall current, optimized the flow turbulence state, slowed down water velocity, improved the fish ability of crossing of fish pass.
3) utilize the arcuate structure characteristics of arch dividing plate, drain the fish pass basic sediment, can realize the effect of automatic desilting, keep the good water environment of fish pass by the husky hole of mistake that is positioned at two corners, dividing plate bottom.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the arrangement sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of ecological fish pass arch dividing plate, the arch rise ratio of arch dividing plate 1 is 0.3, its top was provided with fish notch 2; Cross fish notch 2 and be V-type, groove wedge angle degree is 60 °, and width is 0.4m, highly is 1.1m; Flowing hole 3 has three, and diameter is 15cm, is located at dividing plate 1 bottom.Three flowing holes 3 are the del setting, above two flowing holes 3 and the V-type groove point of crossing fish notch 2 be positioned at sustained height, and bilateral symmetry, another flowing hole 3 was positioned at the centre position of fish notch 2 grooves point and dividing plate bottom.Crossing two corners that husky hole 4 is positioned at dividing plate 1 bottom, is 60 ° of circular arcs, and single hole area is 64cm2.
As shown in Figure 2, be the arrangement diagram of a kind of ecological fish pass arch dividing plate of the utility model.In the gradient is 1: 10 rectangle fish pass 5, be pitch arrangement with a plurality of arch dividing plates with 2m along water (flow) direction, each dividing plate and 6 one-tenth 45 ° of fish pass base plates, arch dividing plate projecting surface is towards the upper reaches.
Adopt technique scheme, the fish pass fluid stable do not have strong turbulent flow phenomenon, and the current gas saturation is controlled, no silt sediment in the fish pass, and the ability automatic desilting has ensured the good water environment of fish pass and has crossed the fish function.
