The invention discloses an adjustable fishway system in the field of fishway technology, which includes a tailwater section buoyancy box, a connecting section buoyancy box, a river channel buoyancy box, an observation section buoyancy box, a fish collection section buoyancy box, and a concrete support rail. Both sides of the connecting section buoyant box, the river channel buoyant box, the tailwater section buoyant box, the observation section buoyant box, and the fish-collecting section buoyant box are all fixedly equipped with fixed bins and pulleys; Disassemble and adjust the number of buoyancy units, thereby adjusting the buoyancy of the entire buoyancy tank, so that the distance from the bottom surface of the floating Y-shaped fishway to the water surface reaches a preset value. When the downstream water level changes, the Y-shaped fishway does not rely on external forces Under the effect of buoyancy, it will automatically adjust to a new equilibrium position, so as to maintain a good water depth and flow rate, so that fish can migrate according to the set plan, and continue to meet the requirements of fish protection in the field of environmental protection.
Description
technical field [0001] The invention relates to the technical field of fishways, in particular to an adjustable fishway system. Background technique [0002] At present, after the construction of water conservancy and hydropower projects, fish cannot migrate normally. The existing fishways are fixed by concrete pouring. When the water flow used to lure fish changes, the water depth and flow velocity in the fishway will change, making it impossible for fish to migrate according to the design plan, and the protection of fish in the environmental protection field cannot be sustained. requirements. [0003] Based on this, the present invention designs an adjustable fishway system to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide an adjustable fishway system to solve the problem in the prior art mentioned in the above background art that after the construction of water conservancy and hydropower projects, fish ca...
