摘要
为防止三河闸泄洪时船舶在水流作用下意外撞击闸门发生事故,需要在上游引河适当位置设置可靠的拦船设施。摩阻型拦船设施结构简单,投资不大,拦截能力强,适用于三河闸,它由摩阻机、摩阻机基础、钢丝绳和浮桶组成。针对三河闸水面较宽、流速较大的特点,基于动力学原理,采用微分法计算,最终确定了钢丝绳型号、长度以及摩阻机参数。
In order to prevent ship accidentally impact on the gate under the action of water flow when the Sanhe Sluice releases floods, a reliable ship blocking facilities needs to be set up at proper place in the upstream of the river. The friction type ship blocking facilities have the advantages of simple structure, small investment and strong interception ability, which is suitable for Sanhe Sluice. It consists of a friction machine, a friction machine foundation, a steel wire rope and a floating bucket. According to the characteristics of wide water surface and large flow velocity of Sanhe Sluice, based on the principle of dynamics, differential method is adopted to calculate and finally determine the type, length and friction machine parameters of wire rope.
