Embodiment Construction

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Fish pass is an important channel for ecological fish reproduction, migration and migration. The fishway is mainly divided into orifice type, overflow weir type, vertical slot type and other forms. Among them, the vertical slot fishway is the most widely used. The common vertical slot fishway includes straight wall type partition and L-wing type partition Two forms, the straight wall type partition is used more in northern my country, which is characterized b...

Abstract

The invention discloses a vertical seam type fishway step type water surface calculation method which is particularly suitable for calculating upstream and downstream water depth, water surface level difference and vertical seam flow velocity of a fishway partition plate in a non-uniform flow state. The method comprises the following steps: establishing a flow velocity formula and a flow formula at a vertical seam according to an energy equation, determining a flow coefficient, and calculating the water depth and water level difference of upstream and downstream steps of the vertical seam, the flow velocity of the vertical seam and the like. Calculation results can be used for reasonably determining the height, the longitudinal gradient, the length, the side weir size and the like of the fishway side wall, and the defects of fishway hydraulic design are overcome.

Description

technical field [0001] The present application relates to the technical field of water conservancy engineering, and in particular, to a method, a device and a storage medium for calculating a stepped water surface of a vertical slot fishway. Background technique [0002] Hydropower is a clean energy power generation, which is widely used in my country. One of the problems brought about by the development of hydropower is that humans destroy the migration of fish, which has an impact on the migration of fish in the water system. [0003] In view of this situation, repairing the fish way has become the current solution to the problem. Fish pass is an important channel for ecological fish reproduction, migration and migration. During the construction of artificial fishway, the water surface line is in a stepped state, especially the non-uniform flow, but there is no method to calculate the water surface line in the stepped state. SUMMARY OF THE INVENTION [0004] The embodi...
