Description
Technical field
The utility model relates to a kind of vertical shaft type fish pass.Be applicable to Hydraulic and Hydro-Power Engineering.
Background technology
Water power hydraulic engineering can provide the comparatively clean energy, but the impact of Hydraulic and Hydro-Power Engineering on ecological environment is huge, particularly on the impact of local river ecological environment, building up of such as dam improves water level, block river, make fish be difficult to migration, particularly almost extinction is brought for the fish needing migration to lay eggs.At present comparatively ripe technology builds fish pass in water power hydraulic engineering, thus make fish can migration smoothly.Fish pass intercepts as slowing down fish the restoration of the ecosystem measure affected by water power hydraulic engineering, more and more receive the concern of various circles of society and environmental protection administrative responsibile institution.But existing fish pass floor space is large, input cost is high, increase engineering burden.
the patent No. is the Chinese patent of 201310376941.0, disclose a kind of spiral water tank type fish pass, ring pole structure is straight up built in dam downstream, this ring pole structure elevation is suitable with crest elevation, press along ring pole structure outer wall or inwall surrounding and calculate gradient screw arrangement water tank type fish pass, this fish pass rises to upper pond level step by step by the level of tail water.This patent is that ring pole structure floor space is straight up little, but in this patent, fish pass adopts circulating type arrangement upwards, increases fish pass length, improves fish migration difficulty.--。
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing, provide that a kind of structure is simple, easy construction, floor space is little, input cost is low vertical shaft type fish pass, to reduce fish migration difficulty.
The technical scheme that the utility model adopts is: a kind of vertical shaft type fish pass, it is characterized in that: this fish pass comprises rectangle vertical shaft, some transfer ponds are provided with in rectangle vertical shaft, described transfer pond is arranged in the two ends of rectangle vertical shaft length direction, and the transfer pond at two ends is arranged at interval straight up, adjacent two transfer ponds, rectangle vertical shaft length direction two ends are connected by U-shaped canal, and U-shaped canal water inlet is communicated with the top in transfer pond, one end, and delivery port is arranged in the top in other end transfer pond.
Top, described transfer pond, corresponding on it U-shaped canal delivery port position be provided with core wall.
The unhurried current pillow of some vertical channel water flow path directions is provided with bottom described U-shaped canal.
Described unhurried current pillow is semicircle cement bar.
Described rectangle shaft wall has some blow vents.
The beneficial effects of the utility model are: in the utility model, fish pass is that broken line is arranged, opposed helical ascending manner fish pass substantially reduces fish pass length.Unhurried current pillow being set in the utility model bottom U-shaped canal, for slowing down flow rate of water flow, reducing fish upwards migration difficulty.The utility model floor space is little, and structure is simple, easy construction, and engineering drops into lower.
Accompanying drawing explanation
Fig. 1 is the top view of embodiment.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the sectional view of U-shaped canal in embodiment.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the present embodiment have on rectangle vertical shaft 1(rectangle vertical shaft 1 borehole wall have some blow vents), upwards, along the U-shaped canal 3(of piecewise dam axis some Fig. 3 is seen at rectangle vertical shaft 1 inner vertical, U-shaped canal cross section is U-shaped, current can be concentrated), and arrange transfer pond 3 at the turning point of broken line.In this example, transfer pond 2 is arranged in the two ends of rectangle vertical shaft 1 length direction, and the transfer pond 2 at two ends is arranged at interval straight up.U-shaped canal 3 water inlet is communicated with the top, transfer pond 3 of one end, and delivery port is positioned at the transfer pond of other end transfer pond 3(a little less than water inlet) middle part above and delivery port is positioned at below this transfer pool water level.
In the present embodiment on top, transfer pond 2, corresponding on it U-shaped canal 3 delivery port position be provided with core wall 4, transfer pond 2 upper part is divided into two parts by core wall 4, and (part is communicated with U-shaped canal 3 water inlet, another part is communicated with the delivery port of U-shaped canal above it), bottom, transfer pond is communicated with.
For slowing down current, being convenient to fish migration, bottom U-shaped canal 3, being provided with the unhurried current pillow 5(of some vertical channel water flow path directions in this example as semicircle cement bar).
The present embodiment Mesichthyes along U-shaped canal 3 upstream, from swimming bottom core wall 4 to core wall 4 opposite side after entering transfer pond 2, and enters the U-shaped canal 3 above this transfer pond from U-shaped canal 3 water inlet being positioned at this side.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model is also not limited to above-mentioned citing; those skilled in the art; in scope of the present utility model, the change made, change add or replace, all should belong to protection domain of the present utility model.
