Combined facility applied to speed reduction type slow bottom slope aeration
The invention relates to the field of water conservancy and hydropower engineering, in particular to a deceleration type slow-bottom-slope aeration combined facility. The device is arranged in a high-water-head, high-flow-speed, large-water-level variable-amplitude and slow-bottom-slope project, and is connected with a working gate of the project; the combined facility is characterized in that the combined facility comprises a sudden expansion and sudden falling section, three aerators and a connecting gentle slope which are arranged in sequence, the three aerators are the first aerators, the second aerators and the third aerators, and the sudden expansion and sudden falling section is arranged behind a service gate and connected with the service gate; the sudden expansion and sudden fall section is connected with the first aerator through a connecting gentle slope, the first aerator is connected with the second aerator through a connecting gentle slope, and the second aerator is connected with the third aerator through a connecting gentle slope; under the conditions of high water head, high flow velocity and large water level amplitude variation, the flow velocity can be effectively reduced, the flow state is relatively stable, cavitation erosion is avoided, the engineering requirements are met, the flow velocity on the slow bottom slope is reduced along the way, a stable aeration cavity can be formed at each aeration ridge, and the flow state is relatively good.
应用于减速式缓底坡掺气组合设施,涉及水利水电工程领域。本发明设置在高水头、高流速、水位变幅大以及缓底坡的工程中,与该工程的工作闸门连接;其特征在于该组合设施包括顺序设置的突扩突跌段、三个掺气坎和连接缓坡,三个掺气坎分为第一掺气坎、第二掺气坎和第三掺气坎,突扩突跌段设置在工作闸门后方,与工作闸门连接,突扩突跌段与第一掺气坎、第一掺气坎与第二掺气坎、第二掺气坎与第三掺气坎之间均通过连接缓坡连接;本发明在高水头、高流速、水位变幅大的情况下,可有效降低流速,流态较平稳,避免发生空蚀,满足工程需要,在缓底坡上沿程流速降低,且在各掺气坎处均能形成稳定的掺气空腔,流态较好。
