为小水电站设计造价低廉而可靠性高的闸门是工程人员面临的难题。新西兰过去八年来在闸门设计与运行方面取得了以下经验。 1.设计原则在小水电站闸门的设计开始之前,确定详细的设计原则至关重要。必须计算出各种运行条件下闸门上的荷载,除了正常的水力荷载外,还须考虑可能的地震、冰荷载、漫顶及漂流物的影响。吊点必须能承受启门机的最大启闭力,以防止闸门受卡发生事故。
Designing a sluice gate with low cost and high reliability for a small hydropower station is a problem that engineers face. New Zealand has gained the following experience in the design and operation of gates for the past eight years. 1. Design Principles Prior to the design of the SHP gate, it is of crucial importance to determine the detailed design principles. The load on the gate under various operating conditions must be calculated, in addition to the normal hydraulic loads, the possible effects of earthquakes, ice loads, overhangs and drifts. Hanging point must be able to withstand the maximum opening and closing force Kai door machine to prevent accidents by the gate card.
