A fish counting system for fish passing facilities in water conservancy and hydropower projects

Abstract

The invention discloses a fish passing counting system for a fish passing facility of hydraulic and hydropower engineering, and belongs to the technical field of hydraulic and hydropower engineering. The fish passing counting system comprises a fish passing way. A plurality of counting probes are arranged on the two sides of the fish passing way and connected with counters, and meanwhile the counting probes and the counters are connected with a power source at the same time. According to the technical scheme, an infrared counting device is used for inducting a bijection induction device to count the fish passing amount, counting is more accurate and reliable, and the defect that manual counting is likely to go wrong is overcome; continuous counting can be achieved, the final fish passing amount of the fish passing facility can be convenient to estimate accurately, and meanwhile the gathering degree of fishes in the fish passing facility can be reflected; and implementation is convenient, running and maintaining are easy, and establishing of an ecological environment protection facility is facilitated.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and relates to ecological environment protection technology in water conservancy and hydropower engineering, in particular to a fish counting system for fish passing facilities of water conservancy and hydropower projects. Background technique [0002] The construction of water conservancy and hydropower projects usually has adverse effects on aquatic ecology, especially on fish. The main manifestation is that the construction of dams has caused river channel obstruction, resulting in the compression of the living environment of fish resources, thus affecting the genetic normality of fish resources. exchange, eventually leading to the gradual depletion and disappearance of fish stocks. [0003] In order to alleviate this adverse effect, fish passing facilities, such as fishways, fish ladders, and imitation natural passages, are usually installed during the con...

Problems solved by technology

[0004] In order to reflect the fish-passing effect of the fish-passing facilities, at present, artificial observation rooms are usually set up in the fish-passing facilities for manual counting, or cameras are set up to take pictures before counting, resulting in large errors in manual counting, especially counting errors caused by artificial factors More frequent, seriously affecting the accuracy and objectivity of evaluating the effect of passing fish
