The invention relates to a self-locking type hydraulic expansion piece of an underwater automatic lifting device, which comprises a hydraulic expansion piece and a self-locking type two-way valve, the self-locking type two-way valve is communicated with the hydraulic expansion piece through a pipeline, the self-locking type two-way valve comprises a valve body, a valve core with separated space is arranged in the valve body, a valve core hole is formed in the valve core, and the valve core hole is communicated with the hydraulic expansion piece. The valve body is provided with a piston rod penetrating through the valve element hole, the middle of the piston rod can seal the valve element hole, compressed gas exists between the expansion piece barrel and the expansion piece rod, fluid flows into and flows out of the hydraulic expansion piece through the self-locking type two-way valve, and when the self-locking type two-way valve is self-locked, due to the fact that water in the hydraulic expansion piece cannot be compressed, the expansion piece rod cannot move, and the hydraulic expansion piece cannot move. And the water pressure expansion piece can be locked synchronously. The device is arranged on the lifting platform, the function that the device automatically ascends and descends along with the water depth is achieved, when the lifting platform sinks to the target position, automatic locking can be achieved, unnecessary shaking caused by pressure fluctuation of the external environment is eliminated, and the stability of the testing device can be enhanced.
本发明涉及一种水下自动升降装置的自锁式水压伸缩器,包括水压伸缩器和自锁式双向阀,自锁式双向阀通过管道与水压伸缩器连通,自锁式双向阀包括阀体,阀体内设置有分隔空间的阀芯,阀芯中设置有阀芯孔,阀体设置有穿过阀芯孔的活塞杆,活塞杆的中部能够密封阀芯孔,伸缩器筒与伸缩器杆之间具有压缩气体,流体通过自锁式双向阀流入、流出水压伸缩器,自锁式双向阀自锁时,由于水压伸缩器内部水不可压缩,伸缩器杆无法运动,会同步锁死水压伸缩器。本发明装置设置在升降平台上,满足装置随水深自动升降功能的同时,当升降平台下沉至目标位置后,可以自动锁定,消除外界环境压力波动引起的不必要的晃动,能够增强测试装置的稳定性。
