Abstract

The invention relates to the technical field of water conservancy facilities and provides an adjustable aeration ecology landscape retaining dam which comprises an upper dam body, a middle dam body and a bottom dam body. The bottom dam body is fixed to a river bed. A height-adjustable supporting device is connected between the upper dam body and the middle dam body, and a height-adjustable supporting device is connected between the middle dam body and the bottom dam body. The height-adjustable supporting devices are electrically connected with a controller. The upper dam body comprises a first flow-passing surface which comprises a first waterways experiment station (WES) weir surface. The middle dam body comprises a second flow-passing surface, and the second flow-passing surface comprises a second WES weir surface and a first reverse curve surface. The bottom dam body comprises a third flow-passing surface, and the third flow-passing surface comprises a third WES weir surface, a first inclined surface, a second reverse curve surface, a first horizontal surface and a third reverse curve surface which are connected in sequence. According to the adjustable aeration ecology landscape retaining dam, the distances between the three dam bodies can be adjusted according to upland water conditions, accordingly the water passing condition is adjusted, and the concentration of air entrained in water is increased.

Description

technical field [0001] The invention relates to the technical field of water conservancy facilities, in particular to an adjustable aerated ecological landscape dam. Background technique [0002] With the development of cities, water pollution in urban rivers has become an important factor restricting urban economic development. Due to a large amount of urban life and industrial sewage being discharged into the river, the river water is black and smelly, the concentration of dissolved oxygen in the water is insufficient, and the self-purification ability of the water body is reduced or even lost. Therefore, trying to increase the concentration of dissolved oxygen in the water has become the most direct means to improve the self-purification ability of the water body. In order to improve the water quality of urban rivers, departments at all levels have adopted a series of anti-pollution and emission-reduction measures. Although some effects have been achieved to a certain ext...
