The invention relates to a speed and angle variable refining device for a three-dimensional ship bow water-entry slamming test, and the device comprises a test tower, the top of the test tower is provided with a motor, and the lower end of the motor is provided with a height adjustment module, a release device module, a limiting device module and an angle adjustment module from top to bottom. The height adjusting module is connected with a motor through a crane hook; the height adjusting module comprises a first hand-cranking wheel, a small truss and a worm gear lead screw, the first hand-cranking wheel is fixedly arranged on the small truss, the small truss is connected with the crane hook through steel wire ropes arranged at the two ends, and the worm gear lead screw is arranged at the lower end of the small truss. The problem of fine adjustment of the water entry speed and angle can be better solved.

    本发明涉及一种三维船艏入水砰击试验可变速度及角度的精细化装置,包括试验塔架,所述试验塔架顶部设置电机,所述电机下端从上至下设置高度调节模块、释放装置模块、限位装置模块和角度调节模块,所述高度调节模块通过吊机挂钩与电机连接;所述高度调节模块包括第一手摇轮、小桁架和蜗轮丝杆,所述第一手摇轮固定设置在小桁架上,所述小桁架通过设置在两端的钢丝绳与吊机挂钩连接,所述小桁架下端设置蜗轮丝杆。本发明能够更好的解决入水速度及角度精细调整的问题。
