Abstract

The invention discloses an intelligent fishway fish passing effect monitoring device, and relates to the technical field of fish resource protection, the intelligent fishway fish passing effect monitoring device comprises a cleaning cylinder, the outer side of the cleaning cylinder is welded with a connecting arm, the bottom of the inner side of the connecting arm is provided with a bearing, the inner side of the bearing is embedded with a rotating column, and the outer side of the connecting arm is provided with a waterproof shell. The device is scientific and reasonable in structure and safe and convenient to use, the pressure pump is started, so that the spherical glass cover is flushed repeatedly, the water-proof motor is installed on the inner side of the water-proof shell, the water-proof motor is installed on the inner side of the water-proof shell, the water-proof motor is installed on the inner side of the water-proof shell, and a clamping disc is welded to one end of the rotating column, and the spherical glass cover is attached to one end of the clamping disc. At the moment, the originally dirty surface of the outer side of the spherical glass cover can be cleaned, and the outer surface of the spherical glass cover can be alternately cleaned through multiple times of washing, so that the surface, located in water, of the spherical glass cover is always clean, and it is guaranteed that a monitoring camera can shoot fish schools in a fishway clearly all the time during fish school monitoring.
