Problems solved by technology

While the South-to-North Water Transfer Project provides abundant water resources for the north, it also allows some southern organisms to invade the north, causing certain damage to the ecology of the north, and even causing adverse effects on human health.

Embodiment 1

[0024] In embodiment 1, when the device is in normal operation, the device can intercept fish fry through the baffle plate 5, the first filter screen 4 and the second filter screen 9, and the baffle plate 4 is equipped with an ultrasonic fish scrambler, and the ultrasonic fish scrambler can The fry are driven away so that the fish swim back to the first waterway 1. The first filter screen 4 and the second filter screen 9 can repeatedly intercept the fish surface, so that the fry passing rate is reduced. At the same time, the first filter screen 4 and the second filter screen 9 There is a gap between the filter screen 9 and the second water channel 2, which is convenient for the passage of sundries such as algae, and the ultraviolet light chamber 8 can use ultraviolet light to kill fish eggs and remaining fry, and the third filter screen 84 picks up fish eggs and fry , so that the fish eggs and fry are exposed to the air, and the fish eggs and fry are completely killed with ultr...

Embodiment 2

[0025] In embodiment 2, when the width of the first waterway 1, the second waterway 2 and the third waterway 3 are the same, the speed of the water flow in the second waterway 2 is the same as that of the first waterway 1, and the water flow speed is relatively fast, and the fry are easy to flow The impact directly swims through the second water channel 2, which is likely to cause biological invasion.

Embodiment 3

[0026] In embodiment 3, when the inside of baffle plate 5 is not vacuum shape, after a small amount of fish fry swim through baffle plate 4, also be full of ultrasonic waves in the backwater pool 6, now fry can continue to move in disorder, resulting in more Fish fry enter the third waterway, which is easy to cause biological invasion.

Abstract

The invention discloses a device for preventing outside biology from invasion for a South-to-North water diversion project, which comprises a second water channel; one end of the second water channelis connected with a first water channel, the other end thereof is connected with a third water channel, and a first filter screen and a second filter screen are installed on the inner wall of the second water channel through a bracket; both sides of the first filter screen are fixedly connected with a baffle, and one side of the second filter screen far from the first filter screen is fixedly connected with the baffle; both sides of the second water channel are connected with a water returning pond, an ultraviolet lamp room is installed on the third water channel. The device can intercept fries through the baffle, the first filter screen and the second filter screen, an ultrasound wave fish disturber is installed on the baffle, and can expel fishes to make them return the first river channel; the first filter screen and the second filter screen can intercept the fish face for many times, thus the fry passage rate is reduced; meanwhile, a gap is existed between the filter screen and thesecond filter screen and the second river channel, thereby facilitating the passage of algae and other sundries.

Description

technical field [0001] The invention relates to the technical field of preventing biological invasion, in particular to a device for preventing external biological invasion used in the South-to-North Water Diversion Project. Background technique [0002] The South-to-North Water Diversion Project is a strategic project of the People's Republic of China. It refers to the transfer of water resources in the Yangtze River Basin from its upper, middle, and lower reaches to North China, the Huaihai Plain, and the Northwest region in combination with the characteristics of China's territory and regions. In water-shortage areas, the starting point of the east route project is located at Jiangdu Water Conservancy Project in Yangzhou, Jiangsu; the starting point of the middle route project is located at the Danjiangkou Reservoir in the middle and upper reaches of the Han River, and the water supply areas are Henan, Hebei, Beijing and Tianjin. [0003] Biological invasion refers to the...
