Problems solved by technology

Among them, the fishway needs an open terrain to meet the length requirements, and has a great influence on the engineering layout
Both the fish lock and the fish lifter pass the fish through manual auxiliary measures after luring the fish, which not only has a great impact on the engineering layout, but also requires a large investment
Considering the safety issue, the container fishing boat is not suitable for luring fish in the area close to the factory building. The fish luring effect is not good, and the fish will be damaged during the transportation process, and it will consume a lot of manpower and material resources, which will delay the smooth passage of fish over the dam. Disadvantages such as time

Embodiment

[0016] This example picture 1 shown, including reversible pump-turbine 6 , Fish collection system in front of the dam 2 and fish collection system behind the dam 3 , reversible pump-turbine 6 It includes a water turbine with the function of a water pump and a generator, both of which are connected to one shaft. reversible pump turbine 6 One or more units can be set in the unit. The reversible pump-turbine is a Francis turbine with the function of a water pump, which can be assembled directly from the finished reversible pump-turbine sold in the market. Fish collector system in front of the dam 2 And behind the dam fish collector system 3 They are respectively located above the water inlet of the reversible water pump turbine dam and the tail water inlet of the reversible water pump turbine.

[0017] When it is necessary to meet the upward demand of fish, implement the working condition of the water pump, turn on the generator and the fish collection...

Abstract

The invention discloses an upstream and downstream fish dam-passing and communicating device which comprises a dam (1), wherein a fish collection system (2) in front of the dam is arranged at the upstream part of the dam (1); a fish collection system (3) behind the dam is arranged at the downstream part of the dam (1); and a generator (5) is arranged in a power generation plant (4) and is connected with a group of reversible pump turbines (6). The upstream and downstream fish dam-passing and communicating device can meet the requirements that upstream and downstream fishes communicate; the influence on arrangement of hydropower engineering is small; and the operation is simple. The upstream and downstream fish dam-passing and communicating device has positive effects on reduction of the influence of water conservancy and hydropower engineering on fish migration and promotion of river ecological protection.

Description

technical field [0001] The invention relates to an upstream and downstream fish crossing communication device, which belongs to the technical field of fish protection in hydropower stations. Background technique [0002] The construction of dams in water conservancy and hydropower projects has blocked the exchange of fish populations, and fish passing facilities are important facilities for restoring the exchange of aquatic organisms. [0003] Existing fish passing facilities mainly include several forms such as fishway, fish gate, fish lifter and fish collection and transportation system. Among them, the fishway needs an open terrain to meet the length requirements, and has a great influence on the engineering layout. Both the fish lock and the fish lifter pass the fish through manual auxiliary measures after luring the fish, which not only has a great impact on the engineering layout, but also requires a large investment. Considering the safety issue, the container fishi...
