Rail type fish collection tank dam feeding system

Abstract

The invention discloses a rail type fish collection tank dam feeding system. The system comprises a fish collection tank, a lifting car, a winch, a pulling cable, rails, a lifting platform, an inclined table and anchor blocks; the inclined table is located between the lifting platform and the anchor blocks, and the fish collection tank is arranged on the lifting car; the winch is mounted on the lifting platform and is connected with the lifting car through the pulling cable; the two symmetric rails are arranged and are arranged on the inclined table in a manner of being symmetric about the pulling cable; and an overhauling steel ladder is further arranged on one side of the inclined table, and the anchor blocks used for supporting the pulling cable are arranged on the lifting platform and the inclined table. A rail type fish collection tank lifting structure is adopted, rapid and stable lifting and dam feeding of the fish collection tank at the downstream position of a high-dam large reservoir under the large-fall condition can be achieved, and therefore the aims of fish passing of the upstream position and the downstream position of a high dam and fish gene exchange are achieved; and the adverse effect of development of water conservancy and hydropower engineering on the aquatic environment is effectively relieved, and the powerful technology support is provided for building the green environment-friendly water conservancy and hydropower engineering.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering environmental protection, and in particular relates to a rail-type fish-collecting box dam upper system. Background technique [0002] In the development of water conservancy and hydropower projects, the blocking of fish communication channels and fish gene exchange in the upstream and downstream of the dam site are the most important environmental problems that need to be solved urgently in the construction and operation of the dam site. For this reason, the environmental protection administrative department Generally, in view of the protection of fish involved in the development of water conservancy and hydropower projects and the degree of impact, the requirements for the construction, operation and related research of fish passing facilities upstream and downstream of the dam site are put forward, such as fishways, fish gates, fish elevators, and fish collec...

AI Technical Summary

Problems solved by technology

[0003] At present, the 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. High dams Many core issues of fish passing technology in large reservoirs have not yet been studied and solved. There are few examples of mature technology, better fish passing effect, and easy operation and implementation. dam problem, and there is a lack of more effective methods

However, the use of the cableway fish-collecting box dam system has strict requirements on the safe operating conditions of the system, and it cannot be operated under adverse weather conditions such as strong winds, snowstorms, and nights. Under normal circumstances, the operating speed should be kept stable and uniform, and the speed variation should not exceed ± 5%, lightning protection and grounding devices should be arranged according to the actual conditions of the installation area, and effective testing, inspection, maintenance, overhaul, recording and other safety production work systems and operation systems should be established; the carrying capacity is limited, and should be 3t~ 6t; the structure cost of cableway and upstream and downstream transfer platforms is high
