Embodiment
[0055] By setting a counting device for counting fish at the fishway, it is possible to provide accurate and reliable data for scientific research on fishery resources in waters within a long period of measurement. At the same time, by scientifically analyzing the collected data, it is also possible to conduct scientific and effective assessments of the ecological environment.
[0056] However, in the prior art, due to the long measurement period and the complicated operation process of installing the counting device in the fishway, it is very inconvenient to maintain the counting device that has counted fish during the service period.
[0057] At the same time, in the long-term measurement period, the existing equipment often adopts the method of replacing the device to adjust the statistical range of passing fish.
[0058] In summary, in the prior art, the counting device for counting fish mainly has the following problems:
[0059] 3. The installation and maintenance workf...

The invention relates to the field of fishery research technical equipment, in particular to an infrared scanning and counting device for passing fish through a fishway. An infrared scanning and counting device for passing fish in a fishway comprises a fixed frame, a movable frame and an adjustable grid. The fixing frame is used for fixing in the fishway, and the fixing frame includes a first frame body arranged under the water surface and a second frame body located outside the water surface. The movable frame is movably connected with the fixed frame, and the movable frame is used to cooperate with the first frame body or the second frame body. The adjustable grid is arranged on the outer peripheral surface of the movable frame. There is also a monitoring device at the exit. The fish pass infrared scanning and counting device is convenient for maintenance and other work in the process of use, can effectively reduce the cost of use and maintenance, and reduce the labor intensity of the staff. Secondly, the infrared scanning and counting device for fish passing through the fishway can adjust the size range of the fish passing by, so as to meet the needs of monitoring in a long time, and effectively reduce the cost of use.
Description
technical field [0001] The invention relates to the field of fishery research technical equipment, in particular to an infrared scanning and counting device for passing fish in a fishway. Background technique [0002] By setting a counting device for counting fish at the fishway, it is possible to provide accurate and reliable data for scientific research on fishery resources in waters within a long period of measurement. At the same time, by scientifically analyzing the collected data, it is also possible to conduct scientific and effective assessments of the ecological environment. [0003] However, in the prior art, due to the long measurement period and the complicated operation process of installing the counting device in the fishway, it is very inconvenient to maintain the counting device that has counted fish during the service period. [0004] At the same time, in the long-term measurement period, the existing equipment often adopts the method of replacing the devic...
