A driving device for tilting fishway

Abstract

The invention discloses a driving device for tilting a fishway. The output shaft of a main motor is arranged upwards, a gear is connected to the output shaft, a rotating outer cylinder is arranged above the main motor, and the bottom of the rotating outer cylinder is connected to the main motor. There is a gap, the bottom of the rotating outer cylinder has an upwardly protruding cavity, and there are tooth grooves on the inner wall of the cavity. The gear on the output shaft of the main motor is located in the cavity, and the gear meshes with the tooth groove of the cavity, and the main motor drives The rotating outer cylinder rotates, the second straight bevel gear is fixedly set on the outer wall of the rotating outer cylinder, the first straight bevel gear is arranged on the inclined fishway, the first straight bevel gear meshes with the second straight bevel gear, and the main motor drives the rotating outer cylinder The cylinder and the straight bevel gear two rotate together. The driving device of the present invention can be automatically started by the water level detection device, and can realize the switch between automatic fish feeding and electric driving fish feeding, so as to ensure the normal use of the fishway.

Description

technical field [0001] The invention relates to the technical field of water conservancy projects, in particular to a driving device for tilting fishways. Background technique [0002] At present, there are many types of fishways, mainly technical fishways and ecological fishways such as pool-type fishways, baffle-type fishways, and vertical-slotted fishways. The design goals are often single, mainly for one or two main economic fishways Or national key protected fish, but there are generally dozens or even hundreds of fish species in the natural river water ecosystem, and the migration periods and migration flow rates of various fish are different, so the traditional fishway has great limitations. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the above-mentioned technologies, and propose a driving device suitable for inclined fishways, which can be applied to graded fishways arranged on an incline. [0004] To achie...
