Fish releasing device for water conservancy and hydropower engineering

Abstract

The invention discloses a fish releasing device for water conservancy and hydropower engineering. The device comprises a pipeline and a fish carrying tank; a flow dividing pipe is arranged under the pipeline, and one side of the flow dividing pipe is provided with flow dividing through pipes; one side of the fish carrying tank is provided with an oxygen bottle, one side of vertical plates is provided with a push-pull plate, and the outer surface of the push-pull plate is provided with a control valve; the inner surface of the fish carrying tank is provided with a heat insulating layer, one side of the heat insulating layer is provided with a partition plate, and the partition plate is fixedly connected with the fish carrying tank through the heat insulating layer; two sides of the partition plate are each provided with buoyancy balls and flexible lines; and the outer surface of the heat insulating layer is provided with fixing bolts. According to the fish releasing device for the waterconservancy and hydropower engineering disclosed by the invention, an anti-slip mat layer, the buoyancy balls and the flexible lines are arranged, so that stability of the whole device can be increased, stability of the living environment of fishes can be maintained, and the fishes can be prevented from jumping out of the fish carrying tank and being hurt; and the device has good ventilation, issuitable for different working conditions, and brings better use prospects.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower projects, in particular to a fish release device for water conservancy and hydropower projects. Background technique [0002] Due to environmental pollution and overfishing, the species and quantity of fish in natural rivers are decreasing year by year. In order to restore fish resources and biodiversity, artificial multiplication is adopted, and rare and endangered fish and main economic fish are released into rivers every year, while meeting reasonable requirements. fishing needs. Usually, rainproof cloth is laid along the slope of the bank, and mechanically pumped water is released from the top to form an artificial water flow, like a waterfall, but the water flow is relatively shallow. The advantage of this release method is that it is easier for vehicles and personnel to operate, but it is far away from the water surface of the river, and some river banks have a large slope. W...

Problems solved by technology

[0003] There are certain disadvantages in the use of the existing fish release device. First, placing between the strong spring columns on the ground is easy to scratch the floor and affect the aesthetics of the floor. Convenience has brought a certain impact on the use of fish releasing devices. Therefore, we propose a fish releasing device for water conservancy and hydropower projects
