Problems solved by technology

[0002] In the prior art, people usually adopt the linear fixing method to block the river to raise fish. The materials used are mainly barbed wire or polyethylene nets to block the river, and they are fixed on stones or concrete. The disadvantage is that when the water volume and flow are large or When there is a lot of floating and suspended matter, it will be washed away, and the effect of blocking fish will not be achieved.

Embodiment Construction

[0011] In Hexin’an’s triangular column 1, its height is slightly higher than the highest water level in history. The bottom surface of the column is arc-shaped, and its arc is adapted to the turntable cylinder 4. Behind the triangular column 1, two rotating shafts 3 are placed on the river bed. Stand the rotating shaft 3 near the coaming plate 7, lay the lower rail 14 on the river bed, set up some pillars 11 in the middle of the lower rail (depending on the width of the river surface to determine the number of pillars) pillars 11, fix the crossbar 5 on the pillar, and install the upper rail under the crossbar 5 Rail 6, install the slider 12 on the lower rail and the upper rail, and then connect the slider 12 and the mesh 13 as a whole, the mesh 13 can rotate around the axis, and can remove suspended matter in the water. There are two railings 2 that can float on the water on both sides of the railing, and the two ends of the railing 2 are respectively connected with the triangu...

Abstract

The method for fish-breeding across a river is characterized by that it utilizes a cross bar fixed on river surface to guide the discards and wastes floating on the water surface to the shoreside and removes them, and a screen sheet capable of making rotary movement is mounted on the river bed for removing suspended matter in the water, and the screen sheet, baffle plate and enclosing plate are used for separating river so as to attain the goal of breeding fish and removing discards, wastes and suspended matters from fish-breeding area.

Description

Technical field [0001] The invention relates to a method for raising fish by blocking rivers. Background technique [0002] In the prior art, people usually adopt the linear fixing method to block the river to raise fish. The materials used are mainly barbed wire or polyethylene nets to block the river, and they are fixed on stones or concrete. The disadvantage is that when the water volume and flow are large or When there is a lot of floating and suspended matter, it will be washed away, and the effect of blocking fish will not be achieved. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a method for blocking fish in rivers, which can realize blocking fish in large and small rivers. [0004] The technical solution adopted by the present invention to solve the technical problem is: the triangular pillars in the center of the river are vertically fixed on the river bed and are higher than the historical high...
