Problems solved by technology

Rigid enclosures are generally fixed. Small superheights will easily cause the exchange of lake water inside and outside the enclosure. Large superheights will affect light and atmospheric reoxygenation. Flexible enclosures will float with the water, making it difficult to accurately grasp the volume of enclosed water. At the same time, sampling is random and unscientific

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Referring to the accompanying drawings, the main body of the lake ecological experiment enclosure is composed of vertical piles 1, horizontal piles 2, impermeable canvas 6, floating balls 5, pulleys 3, siphon sampling system and stone dragon 7, etc. A slideway 4 is arranged on the vertical pile, a pulley 3 is arranged on the horizontal pile, and the horizontal pile 2 and the floating ball 5 are rigidly connected. The lower end of the impermeable canvas 6 is connected with the stone dragon 7, and the upper end is connected with the horizontal pile 2. The siphon sampling system consists of a siphon sampling tube, a sampling container 11 and a portable vacuum pump. The siphon sampling pipe adopts a plastic hard pipe 8 at the inner part of the enclosure, and a plastic hose 9 at the outer part of the enclosure, and each sampling pipe is provided with a valve 10 . ...

Abstract

The invention provides an automatic height-adjustment lake ecological experimental enclosure with a siphon sampling function. The main body of the experimental enclosure comprises a fixed wood pile, a watertight canvas, a floating ball, a pulley, a siphon sampling system and a stone dragon. The fixed wood pile comprises a vertical pile and a transverse pie; the vertical pile is used for determining the size of the enclosure; the transverse pile is in rigid connection with the floating ball; and the pulley and the floating ball are used for adjusting the enclosure to exceed the height. The lower end of the watertight canvas is connected to the stone dragon, and the upper end of the watertight canvas is connected to the transverse pile. The enclosure is arranged in a quadrate shape, and the side length of the quadrate is 3-5m. The enclosure is provided with the fixed siphon sampling system. The enclosure has the advantages that the enclosed water amount is calculated easily, the experiment scale is proper, the exchange of the lake water in and out of the enclosure is effectively obstructed, the illumination and atmosphere reaeration are ensured, the sampling method is convenient and scientific and the like.

Description

technical field [0001] The invention relates to a lake experiment device, in particular to a fully enclosed rigid enclosure device for ecological restoration experiments for improving the water quality of lakes. Background technique [0002] Lakes are important water resources for our survival. With the rapid development of industry and agriculture and the continuous expansion of cities, a lot of pollutants are discharged into lakes, which seriously degrades the water quality of lakes and causes a series of environmental problems such as eutrophication. The restoration of lake water quality mainly includes physical, chemical and ecological restoration methods. At present, the ecological restoration technology based on plants or plant-animal biological chains is widely used. Because the geographical environment of each lake is different, the dominant species in the lakes are different, so in order to obtain a better restoration effect, it is necessary to obtain reliable data...
