Vertical lifting and horizontal transferring system for fish collection box

Abstract

The invention discloses a vertical lifting and horizontal transferring system for a fish collection box. The system comprises a vertical support frame, wherein a top cover is arranged at the top end of the vertical support frame; a transverse support frame is arranged in the middle of the vertical support frame; a movable notch is formed in the middle of the transverse support frame; winch rails are mounted at the top of two sides of the movable notch; a transfer trolley is arranged on the winch rails; a winch is mounted on the transfer trolley; the bottom end of the winch is connected with a sling; a lifting hanger is mounted at the tail end of the sling; a bottom frame is arranged on the surface of an upper platform; trolley rails are mounted at the tops of a lower platform and the bottom frame; the transfer trolley is arranged on the trolley rails; a fish collection box matched with the lifting hanger is arranged on the transfer trolley. According to the system disclosed by the invention, negative influence of development of water resources and hydropower engineering on the aquatic environment is effectively relieved, a powerful science and technology support is provided for building environmental-friendly water resources and hydropower engineering, and the economic, social and environmental benefits can be remarkable.

Description

Technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering environmental protection, and in particular to a vertical lifting and horizontal transfer system for a fish collecting box. Background technique [0002] Water conservancy and hydropower project development involves the barrier of upstream and downstream fish communication channels and fish gene exchange in the dam site, which are the most important and most urgent environmental problems to be solved in its construction and operation. For this reason, environmental protection administrative departments generally focus on water conservancy and hydropower The project development involves the protection of fish and the degree of impact, and the requirements for the construction, operation and related research of the upstream and downstream fish passing facilities of the dam site, such as fish passages, fish gates, fish lifts, fish collection systems or different combina...

AI Technical Summary

Problems solved by technology

[0003] At present, fish passing technology and related research and development of low-head water conservancy and hydropower projects are relatively mature and there are many application examples, but the large drop and long-distance fish passing problems of high-head reservoir dams have always been technical problems worldwide. Many core issues of fish passing technology have not yet been studied and solved. There are few examples of mature technology, good fish passing effect, easy operation and implementation. There is a lack of more effective methods for the problems of going up and crossing the dam and horizontal transfer
