Embodiment Construction

[0035] In the following detailed description, certain exemplary embodiments of the present invention are shown and described, simply by way of illustration.

[0036]The present invention will be further described below in conjunction with the accompanying drawings.

[0037] figure 1 It is a schematic diagram of the overall plan layout of the river channel temperature rise fish attracting device according to the present invention, which only includes the heating system arranged at the channel side wall Rw adjacent to the fishway mouth Fi; figure 2 is similar to figure 1 Schematic diagram of the overall layout of the water flow temperature rise fish attracting device, the difference is that the heating system is arranged at the side wall Rw of the opposite river near the fishway mouth Fi.

[0038] like figure 1 As shown, the river channel temperature-rising fish attracting device according to the present invention is applied in the river channel R, including the heating syst...

Abstract

The invention discloses a river channel temperature rising and fish guiding device which comprises a heating system. The heating system is arranged on the river channel side wall, close to a fish channel opening, of a river channel. The heating system comprises multiple stages of heating chambers, and a water output pipe connected with the multiple stages of heating chambers through a flow passingchamber, wherein the heating chambers are parallel to the water flowing direction of the river channel and are arranged close to the river channel side wall, the multiple stages of heating chambers are connected sequentially, and a heating coil is arranged on the bottom of each heating chamber. According to the river channel temperature rising and fish guiding device, by utilizing sensibility offishes to temperature, the fish passing rate of a fish channel is increased.

Description

technical field [0001] The invention relates to the fields of water conservancy and hydropower engineering and the ecological environment, in particular to a fish-passing building, and more particularly to a river channel temperature-rising fish-inducing device. Background technique [0002] Fishway is an engineering measure to help fish go up. Building dams and other water conservancy projects on rivers cuts off the way for fish to migrate and spawn. By building fishways, fish can go up during the migration season, thereby Maintain the ecological balance of the river section. [0003] Fishway is a special facility to help fish pass through barriers such as dams smoothly, and plays an irreplaceable role in maintaining the continuity of rivers and the communication of biological populations. The success of fishway structures is one of the evaluation indicators for the health of the river ecosystem, and it is also an important evaluation indicator for ecological environment p...
