The invention discloses an adjustable fishway system in the technical field of fishways. The adjustable fishway system comprises a tail water section buoyancy tank, a connecting section buoyancy tank, a riverway buoyancy tank, an observation section buoyancy tank, a fish collecting section buoyancy tank and a concrete supporting rail; and the two sides of the connecting section buoyancy tank, the two sides of the riverway buoyancy tank, the two sides of the tail water section buoyancy tank, the two sides of the observation section buoyancy tank and the two sides of the fish collecting section buoyancy tank are each fixedly provided with a fixed bin and a pulley. According to the adjustable fishway system, the buoyancy of a whole floating box can be adjusted by disassembling and assembling the first floating blocks of the fixed bins and adjusting the number of the buoyancy units, so that the distance from the bottom surface of the floating type Y-shaped fishway to the water surface reaches a preset value; and when the downstream water level changes, the Y-shaped fishway can be automatically adjusted to a new balance position only under the action of the buoyancy without depending on the action of external force, so that good water depth and flow speed are maintained, the fish can migrate according to a set scheme, and the requirement of the environment-friendly field on fish protection is met.
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...
