【摘要】：针对深水卡爪连接器在工作时受到外界环境干扰造成的松动问题,本文设计了新型非螺纹防松机构。根据深水卡爪连接器密封结构特点,对防松机构受力特性进行分析,找出影响锁紧效率的主要因素,确定了卡爪连接器防松机构2个锁紧配合的角度。对卡爪连接器密封结构力学进行受力分析,得出卡爪连接器对拉力载荷的承载能力,计算出防松机构增益系数及防松力。通过运动性能试验,验证了防松压块及解锁压块与防松滑块之间的运动关系;通过等效受载试验,验证了防松机构在外载下具有良好的防松性能。研制的防松机构已经在我国南海水下320 m进行了示范应用,有重要的理论意义和推广价值。
[Abstract]:In this paper, a new non-thread anti-loosening mechanism is designed in order to solve the loosening problem caused by the disturbance of the external environment in the deep-water clip-claw connector. According to the sealing structure characteristics of the deep-water claw connector, the mechanical characteristics of the anti-loosening mechanism are analyzed, the main factors affecting the locking efficiency are found out, and the angles of the two locking fits of the anti-loosening mechanism of the claw connector are determined. The mechanical analysis of the sealing structure of the claw connector is carried out. The load carrying capacity of the claw connector to the tensile load is obtained, and the gain coefficient and the anti-loosening force of the anti-loosening mechanism are calculated. The motion relationship between the anti-loosening block, the unlocking block and the anti-loosening slider is verified by the motion performance test, and through the equivalent load test, it is verified that the anti-loosening mechanism has good anti-loosening performance under the external load. The developed anti-loosening mechanism has been demonstrated and applied in the South China Sea underwater 320 m, which has important theoretical significance and popularization value.
