Abstract

The invention relates to a hole sealing cover plate driving device with water drive. The device comprises a connection base, an inner cylinder, an outer piston and an inner piston, and the inner cylinder, the outer piston and the inner piston are sleeved sequentially from outside to inside; the rear end of the inner cylinder and the rear end of the inner piston are fixedly connected with the connection base, an inner chamber is arranged in the rear middle part of the outer piston and matched with the inner piston, and an outer chamber is arranged in the inner cylinder and matched with the outer piston; the outer chamber and the inner chamber are communicated with a first oil in and out port and a second oil in and out port respectively, and the outer piston is controlled by a liquid flow to stretch relative to the inner cylinder and the inner piston; the inner cylinder is sleeved with a front cylinder body which is connected with the front part of the outer piston, an axial elastic part is arranged between the front cylinder body and the inner cylinder, the front end of the elastic part is connected with the front cylinder body, and the rear end of the elastic part is connected with the inner cylinder. According to the hole sealing cover plate driving device with water drive, the stretching of the device is controlled by a hydraulic valve, when the device is located below certain depth, even hydraulic energy is lost, the device can be ensured to be in a reliable closed state by the water drive, and when the device is located above certain depth, even the hydraulic energy islost, the device can be ensured to be in a reliable started state by the elastic part.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to a driving device for a sealing cover plate driven by hydraulic pressure. Background technique [0002] Underwater equipment or submersibles often have water holes to control their diving or perform special missions, so it is necessary to set up a water hole opening and closing device: on the one hand, when working underwater, close the cover and seal the water hole to reduce Resistance and noise; on the other hand, open the cover when surfacing to facilitate drainage and avoid overturning caused by unbalanced force. [0003] In order to ensure that the sealing cover plate can reliably close or open the water hole, the water hole opening and closing device is often provided with a hydraulic locking function. But in some cases, it is often not desirable for the hydraulic system to work all the time: on the one hand, the hydraulic station that is kept on is noisy; on th...
