A multifunctional environmental protection dam

Abstract

The invention discloses a multifunctional environment-friendly dam. The multifunctional environment-friendly dam comprises a long-strip-shaped dam body composed of a plurality of dam units. Each dam unit comprises a first base, a second base and two water insulation rolled plates, wherein the two water insulation rolled plates are arranged on the same sides of the first base and the second base correspondingly; and grids are arranged on the inner sides of the two water insulation rolled plates correspondingly. A caisson is arranged in a work space. A blocky body, a water purification tank and an ultraviolet irradiation light box are arranged in the caisson. The blocky body made from a hydrophobic adsorbing material, the water purification tank for water purification and the ultraviolet irradiation light box for sterilization are mounted in the caisson to be used for fully purifying river pollution. Fish holes are formed in the bottoms of the bases, the up-down positions of the grids can be adjusted, the height is adjusted according to the seasonal water flow changes and fish breeding seasonal changes, and the river ecology damage is reduced as much as possible while the normal functions of the dam units are ensured.

Description

technical field [0001] The invention relates to the fields of hydraulic engineering and ecological restoration, in particular to a multifunctional environmental protection dam. Background technique [0002] Dams are currently the most widely used structures in solving problems such as water resource utilization and water surface source pollution control. However, existing dams, such as permeable dams that can adjust water levels and retaining dams that buffer water flow, all have unsatisfactory water purification effects. However, ecological overflow dams with better water purification effects have complex structures, are difficult to maintain and manage, affect the reproduction of aquatic organisms such as fish, and easily cause irreparable ecological damage. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art, to provide a multi-functional environmental protection dam, in which grilles and water-resistant...
