Embodiment

[0038] In the present embodiment, the main dimensions of the vertical slit type fish passing effect experimental system are as follows:

[0039] The upstream ram 5-1 and the downstream ram 5-2 can control the opening; the upstream fish rest pool 6 and the downstream fish rest pool 8 are placed horizontally, and both are of the same size, with an inner diameter of 80 cm long and a width of 25 cm. The height is 50cm; the flow rate of the fish passing effect experiment system is 100L / s.

[0040] The water retaining system 7 is made of brick-concrete with a slope of 2.6%; its interior is composed of 10 identical single fish ponds 13 that are all provided with obstacles, and the obstacles are L-shaped long baffles 14 and short baffles. The plate 15 is composed of; the L-shaped long baffle 14 is composed of a transverse baffle 18 perpendicular to the upstream and downstream direction of the water flow and a longitudinal baffle 19 parallel to the upstream and downstream direction of ...

Abstract

The invention relates to a vertical clearance type fish passing effect experimental system which comprises a water inlet system connected with a water circulation system, a water blocking system connected with the water inlet system and a water outlet system connected with the water blocking system. The water circulation system comprises a water suction pump, an overground water pool, an underground water pool, an upstream control valve and a downstream control valve. The water inlet system comprises an upstream flashboard and an upstream fish resting pool. The water blocking system is composed of a plurality of stages of fishponds. The water outlet system is composed of a downstream fish resting pool, a downstream water flow buffering box and an underground water pool. The vertical clearance type fish passing effect experimental system can be used for studying and analyzing hydraulics turbulent energy dissipation problem, a fish migration problem and hydraulics experimental model demonstration, due to the fact that the experimental system and an actual fishway partial project are built with a proportion of 1:1, the flow regime of the water flow in a fish passing facility is truly reflected, and the reliability and the accuracy of a water flow field in a fishway and the analysis of the fish passing effect are further guaranteed.

Description

technical field [0001] The invention relates to the research and analysis of technical issues such as hydraulic turbulent flow energy dissipation, fish swimming ability, fish migration and fish passing buildings, and particularly relates to a vertical slot type fish passing effect experimental system in hydraulic engineering. Background technique [0002] In response to the increasingly prominent demand for electricity, a large number of water conservancy projects have been built on rivers around the world to develop hydropower, such as dams. After building dams and gates on the river, the continuity of the original river has been blocked, the inherent natural characteristics of the river have been changed, and the water environment and water ecological environment conditions upstream and downstream of the gate and dam have been relatively greatly affected. Generally speaking, after the construction of diversion gates and dams, the environmental factors of fish habitats, suc...
