[0002] While water conservancy and hydropower projects play their benefits of flood control, power generation, shipping, etc., they also have an undeniable impact on the ecological environment, especially the impact of blocking the fish migration channels. Compared with so many dams, up to now, the number of fish passing facilities built in China is less than a hundred, and the problem of blocking fish migration channels within the basin is still very significant. At present, China has entered the stage of ecological civilization construction, and it is very necessary to restore the fish migration channels of existing projects and repair the river ecosystem.
[0003] As an ecological protection measure to restore fish migration channels, fish passing facilities have been adopted internationally for more than 300 years, which play a role in restoring fish migration channels and communicating the gene exchange of fish populations upstream and downstream. Fish passing facilities mainly include fish collection, transportation, and release, among which the most important link is the fish collection process; fish collection facilities mainly include fish collection channels, fish driving facilities, fish lifting machines, fish collection hoppers, etc.; when fish enter the fish collection channel, the fish driving facilities are used to disturb the fish group to approach the fish collection hopper, and the fish collection hopper is lifted to complete the fish collection process; whether the fish group entering the fish collection channel can be smoothly driven into the fish collection hopper becomes an important link in the fish collection process. The existing fish driving method usually uses a fish driving vehicle to drive the fish driving grid below to move back and forth on the running track to complete the process of driving the fish group in the fish collection channel.
[0004] The deficiencies of the existing technology are that the fish driving grid moves back and forth on the bottom track of the fish collection channel, and the width of the fish driving grid is equivalent to the width of the fish collection channel but there is a certain gap. The bottom track is easily covered by silt, and both sides are easily stuck by sundries in the water, resulting in the abnormal operation of the fish driving device and affecting the fish collection effect.
