Nuclear power water taking open channel trash holding device
The invention discloses a nuclear power water taking open channel trash holding device which comprises five trash holding nets, a second trash holding net and a third trash holding net are located on the two sides of a first trash holding net respectively, the second trash holding net is fixedly connected with the first trash holding net, and the third trash holding net is fixedly connected with the first trash holding net. The fourth trash holding net and the fifth trash holding net are perpendicular to the longitudinal axis direction of the water taking open channel, one end of the fourth trash holding net is connected with the second trash holding net, one end of the fifth trash holding net is connected with the third trash holding net, and the other end of the fourth trash holding net and the other end of the fifth trash holding net are connected with the two sides of the water taking open channel respectively. The first trash holding net is perpendicular to the longitudinal axis direction of the water taking open channel, an included angle theta is formed between the second trash holding net and/or the third trash holding net and the longitudinal axis direction of the water taking open channel, and the range of the included angle theta is-18.3 degrees to 18.3 degrees. By limiting the included angle range between the second trash holding net and the longitudinal axis direction of the water taking open channel and between the third trash holding net and the longitudinal axis direction of the water taking open channel, the overflowing capacity of the open channel interception facility is improved under the foreign matter emergency situation, and the requirement for the cold source water taking amount is met.
本发明公开了一种核电取水明渠拦污装置，该装置包括五个拦污网，第二拦污网和第三拦污网分别位于第一拦污网的两侧，第二拦污网与第一拦污网、第三拦污网与第一拦污网之间固定连接，第四拦污网和第五拦污网与取水明渠纵轴线方向垂直，第四拦污网的一端与第二拦污网连接，第五拦污网的一端与第三拦污网连接，第四拦污网与第五拦污网的另一端分别与取水明渠的两侧连接；第一拦污网与取水明渠纵轴线方向垂直，第二拦污网和/或第三拦污网与取水明渠纵轴线方向之间存在夹角θ，夹角θ范围为‑18.3°～18.3°。本发明通过限定第二拦污网、第三拦污网与取水明渠纵轴线方向之间的夹角范围，使得在异物突发状况下，提高明渠拦截设施的过流能力，保证冷源取水量的要求。
