Embodiment Construction

[0037] The technical solution of the present invention will be described in more detail below in conjunction with specific embodiments and accompanying drawings.

[0038] Such as Figure 5 As shown, as shown, the top of the shaft part 27 is connected to the platform 28, and the electronic compass 29 is installed on the top of the shaft part, and the angle signal of the platform 28 is sent to the lower computer in real time through the cable.

[0039] The bottom of the shaft part 27 is free to rotate and sits on the disc 26 . The chassis is secured to the disc 26 by bolt fasteners.

[0040] Four hydraulic propulsion mechanisms are arranged symmetrically along the circumference of the chassis on the upper surface of the chassis. Each hydraulic propulsion mechanism includes a locking block 1, a transition cylindrical block 2, a screw nut pair 3, a driving gear 4, a passive gear 5, a gear box 6, and a hydraulic motor. 7.

[0041] The locking block 1 is connected with the transi...

Abstract

The invention discloses a hydraulic locking device used for an underwater butt-joint shaft part and a locking method for the hydraulic locking device. The device comprises a bracket mechanism, a hydraulic oil device, hydraulic propulsion mechanisms, an angle detecting device, a pressure detecting device and an upper computer, wherein the bracket mechanism comprises an upper shaft sleeve, a connecting lug, a connecting frame and a connecting disc; the outer wall of the shaft part is connected with upper shaft sleeve rotary support through a bearing; the connecting lug is connected onto the outer wall of the upper shaft sleeve; the connecting lug is connected with one end of the connecting frame; the other end of the connecting frame is supported in water after being connected with the connecting disc; the shaft part is arranged on the center of the connecting disc; the hydraulic propulsion mechanisms are uniformly arranged in the peripheral direction, around the shaft part, of the disc periphery of the connecting disc; and the hydraulic propulsion mechanisms can be used for locking or loosening the shaft part. The device can ensure that each hydraulic propulsion mechanism applies enough locking force to the shaft part, so that guarantee is provided for locking underwater large butt-joint shaft parts of different diameters.

Description

technical field [0001] The invention relates to an underwater docking hydraulic locking device. Background technique [0002] Autonomous underwater vehicles (AUV for short) play an important role in deep sea exploration, underwater construction and other fields. However, due to the limited energy they carry, it is difficult to work continuously underwater for a long time, and they usually need to be salvaged ashore for charging. The underwater docking hydraulic locking device can dock with the AUV, and then perform charging and data exchange to extend the working time of the AUV. Since the current direction in the ocean often changes, in order to ensure the success rate of docking between the AUV and the docking device, it is necessary to adjust the opening direction of the docking device so that it is consistent with the direction of the ocean current. After completing the angle adjustment, the shaft of the docking device needs to be locked to make the angle The position i...
