Right side wall 9 forms the second I-shape construction；
The first adjacent I-shape construction and its between second partition 7 surround the first pond room, near the in the first pond room
The region of two dividing plates 7 forms the first swimming pool 10, and in the first pond room, the region away from second partition 7 forms the first rest pond 11；
The second adjacent I-shape construction and its between the first dividing plate 3 surround the second pond room, near the in the second pond room
The region of one dividing plate 3 forms the second swimming pool 4, and in the first pond room, the region away from second partition 7 forms the second rest pond 5, the
Two swimming pools 4, the first swimming pool 10 are connected.
First baffle 2 is vertically arranged with described first dividing plate 3, left side wall 1 respectively；First baffle 2 is connected to the first dividing plate 3
Middle part along its length.
Second baffle 8 is vertically arranged with described second partition 7, right side wall 9 respectively；Second baffle 8 is connected to second partition 7
Middle part along its length.
First and second dividing plate 3,7 tops are contour with described left and right side wall 1,9, and described first and second dividing plate 3,7 bottoms set respectively
Put on base plate 6.
Spacing between first and second dividing plate 3,7 is the 1/3 of fish pass width, the length of first and second dividing plate 3,7 and described fish
Road width is equal, and first and second dividing plate 3, the distance of centrage to the corresponding left and right side wall 1,9 of 7 Parallel to the flow direction are fish pass width
1/2.
In FIG, a kind of staggered fish pass of I-shaped of this utility model includes base plate 6, left side wall 1, right side wall 9, first and second
Baffle plate 2,8, first and second dividing plate 3,7, first baffle 2 is arranged on left side wall 1, and second baffle 8 is arranged on right side wall 9, described
Fish pass is divided into several first swimming pools 4, the second swimming pool 10 and the first rest pond 5, the second rest pond 11 by dividing plate and baffle plate,
It is interconnected between described first swimming pool 4, the second swimming pool 10, described first rest pond 5 and the first swimming pool 4 are in same pond
In room.Second swimming pool 10, the second rest pond 11 are in the room of same pond.This utility model applies among Hydraulic and Hydro-Power Engineering,
Smooth migration can there is active influence to Fish.In FIG, the direction of arrow is the direction of current, the migration of fish be adverse current and
On, Fish when Hydraulic and Hydro-Power Engineering, just enter among fish pass from the import of fish pass, due to building water during migration
Diuretic electrical engineering can cause the drop in river larger, and therefore the current in fish pass are more rapid, is adding dividing plate and baffle arrangement
Afterwards energy dissipating is carried out to current, and by fish pass from being longitudinally separated into some swimming pools and rest pond.Swimming pool is according to the length of fish pass
Depending on concrete river environment, stream relatively placidity in the first swimming pool 4, be conducive to Fish to save muscle power during migration.
Fish are through after a number of first swimming pool 4.Of short duration rest can be carried out in the first rest pond 5.Due to
, in a waters, the current at dividing plate are more fast, beneficial to the migration of Fish, and remote for one swimming pool 4 and the first rest pond 5
From the first rest pond 5 of dividing plate in a waters, the current at dividing plate are more fast, beneficial to the migration of Fish, and away from
First rest pond 5 current of dividing plate are slower, are especially advantageous for Fish here and regain one's strength, will not increase the length of whole fish pass,
It is particularly suitable for the larger engineering of upstream and downstream current difference, therefore can save the investment of engineering, also will not increase the current stream in fish pass
To it is ensured that fish pass pond interior fluidised form is relatively stable.
Water levels of upstream and downstream drop between the room of pond, avoids fish pass entire length to increase simultaneously, as shown in figure 1, the first swimming pool 4
Identical with the first rest pond 5 length, the second swimming pool 10 is identical with the first rest pond 11 length, and the first swimming pool 4 is stopped with first
Breath pond 5 is connected integral, and the second swimming pool 10 is connected integral with the first rest pond 11, the height of water is identical, it is to avoid current
Because gravity larger change occurs it is ensured that whole fish pass current steady.
