新型浮式系缆装置关键技术及可靠性分析

Key Techniques and Reliability Analysis of A Novel Floating Bollard Device

水位的瞬间变幅对水电站下游直立式码头靠泊安全影响巨大。借鉴船闸浮式系船柱原理提出了新型码头浮式系缆装置,在浮筒上对称地设4个弹簧平衡装置,可有效解决在较大系船缆绳拉力情况下,装置升降过程的不平衡阻力等关键技术问题。经依托金沙江水富港综合码头进行理论计算和模型实验验证表明,该技术是可行的,并可在类似工程中推广应用。

The instantaneous amplitude of water level has great influence on the safe mooring on the vertical-face wharf,which is in the downstream of the hydropower station.Based on the principle of floating bollard of lock,a new kind of floating bollard device is proposed,which refers to four spring balance devices installing symmetrically around the buoys,to resolve the key technical issues,such as unbalanced resistance in the case of the maximum mooring rope tension during its up and down.Through the theoretical calculation and the model test of Jinshajiang Shuifu comprehensive port,the results show that the technique is feasible,and it can be applied in the similar projects.
