Embodiment Construction

[0059] In order to make the objectives, technical implementations and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific examples.

[0060] The construction of barrage structures in natural rivers destroys the upstream and downstream migration passages of fish and affects water ecological diversity. The establishment of the fishway not only realizes the function of the river barrage structures, but also provides fish upstream and downstream migration channels. The multifunctional ship lock combined with the fishway and the operation method thereof can not only solve the problem of navigation of ships but also solve the problem of upstream migration of fish.

[0061] like Figure 1-Figure 18 As shown, the present invention provides a multifunctional ship lock combined with a fishway, the ship lock includes an upper lock head 1, a lower lock head 2 and a lock chamber section 3, wherein the revol...

Abstract

The invention provides a multifunctional ship lock combined with a fishway, and an operation method thereof, and belongs to the technical field of hydraulic engineering equipment and machinery. The multifunctional ship lock comprises an upper lock head, a lower lock head and a lock chamber section, rotary gates are arranged at the upper lock head and the lower lock head respectively, each rotary gate comprises an arc-shaped gate, a gate leaf, a main shaft connected with the gate leaf, a circular cover plate, a supporting disc and a force-bearing telescopic rod capable of adjusting the gate toascend and descend, and the force-bearing telescopic rods are hydraulically driven. The gate leaf is provided with a blade grid with an adjustable opening degree so as to adjust the flow speed of water flow and achieve the fish luring effect. Gear mounting components are arranged at the upper ends of the force-bearing telescopic rods and can adjust and control rotation and lifting of the rotary gates. Lifting grooves are formed in the lock heads of the ship lock, and the rotary gates are controlled by the hydraulic drive telescopic rods to partially settle in the lifting grooves when navigation, flood drainage and the like are needed. The fishway and the ship lock are combined into a whole, so that the cost is saved; and multiple functions of fish luring, rotary fish expelling, navigation,water retaining, flood draining and the like can be achieved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic engineering equipment and machinery, and in particular relates to a multifunctional ship lock combined with a fishway and an operation method thereof. Background technique [0002] A fish pass is a fish-passing structure and an artificial tank for fish to migrate through the barrage. The design of the fish pass mainly considers the upward behavior of fish. In the downstream of the barrage, the fish often rely on the attraction of the current to enter the fishway, and the fish swim upstream in the fishway by their own strength to overcome the flow rate. With the continuous construction of a large number of water conservancy facilities, the living environment of fish has been seriously threatened. The building blocks the water flow upstream and downstream, making the fish in the original river unable to migrate, resulting in the reduction or even extinction of a large number of fish. The existing...
