Easy-to-operate mechanical property testing device for flexible pipe cable in deep sea environment

The invention discloses an easy-to-operate testing device for simulating the mechanical property of a flexible pipe cable in a deep sea high-pressure environment, and the device comprises a deep waterpressure tank, an installation frame, and a flexible pipe cable mechanical property testing device. The testing device is fixedly connected to the installation frame, and the installation frame is fixedly connected to the interior of the deep water pressure tank. The deepwater pressure tank cover is connected with the planetary gear train mechanism through the hand wheel, the planetary gear trainmechanism is connected with the connecting rod sliding block mechanism, and the sliding block and the tank body are sealed in a wedging mode. According to the testing device, the two hydraulic motorsare connected with the corresponding stress sensors to independently apply tension, compression or torsion stress to the to-be-tested flexible pipe cable, independent stretching, torsion and other tests on the marine flexible
