Problems solved by technology

Some non-physical methods, such as electric fish drive technology, can replace the fish-blocking screen at the water inlet of the power station, but the scope of action is limited and there are potential safety hazards, so it cannot be widely used in the fish-passing facilities downstream of the dam

Embodiment Construction

[0036] Below in conjunction with embodiment and its Figure 1-14 The present invention is described in further detail. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0037] A fish-inducing facility, comprising a fish-collecting lamp 701, an echo detector 702, and a fish-lure platform 703, the fish-collecting lamp is placed above the water surface obliquely above the fish-lure platform; the echo detector 702 is placed adjacent to the fish-lure platform The fishway bottom plate of the upper level fishway unit, the fish lure platform comprises net wall 201 and the fish lure device surrounded by net wall 201, and net wall 201 is made up of net wall upper and lower line 203 and net wall post 205, and the fish lure front A front sliding door 209 is arranged on the network wall 201 of the front sliding door 209, and a front sliding door rope 211 is respectively connected to the two ends of the front slid...

Abstract

The invention discloses a fish luring device which comprises a fish gathering lamp, an echo detector and a fish luring table, wherein the fish gathering lamp is placed in a position, higher than the water surface, above the fish luring table; and the echo detector is placed a fishway bottom plate of an upper-stage fishway unit adjacent to the fish luring table. According to the fish luring device, the fish is lured through acousto-optical combination, so that the fish luring efficiency is greatly improved; the irradiation range, distance and intensity of the fish gathering lamp can be adjusted, and the irradiation direction and the irradiation angle can be conveniently adjusted; a searchlight can be locked in any direction and angle, and the adjustment can be easily carried out without too much effort; and besides, the fish luring searchlight has a ventilation channel, so that the heat dissipation of a light body is facilitated, and water and dust are effectively prevented from entering the light body and electrical components.

Description

technical field [0001] The invention relates to a river channel water conservancy project, in particular to an induction facility. Background technique [0002] In the prior art, whether the fish can find the entrance of the fish-passing facility affects the fish-passing effect of the fish-passing facility. Castro-Santosetal. (2009) divided the fishway entrance design into two areas: 1) the induction area, through which fish are induced to the vicinity of the fishway entrance. 2) Entrance area, where fish must be able to detect the entrance of the fishway and choose to enter the fishway. It can be seen that the completion of the whole fish luring process not only needs to attract fish to enter the fishway in the entrance area, but also needs to take other measures to attract fish to enter the entrance area through the induction area. Fish are sensitive to flow field, sound, light and air. How to use these external factors to induce fish to quickly find the entrance of the ...
