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 and a locking method for underwater docking shaft parts. The device includes a support mechanism, a hydraulic oil device, a hydraulic propulsion mechanism, an angle detection device, a pressure detection device and a host computer, wherein , the support mechanism includes an upper shaft sleeve, a connecting ear, a connecting frame and a connecting plate, the outer wall of the shaft part is connected to the upper shaft sleeve through a bearing for rotational support, the connecting ear is connected to the outer wall of the upper shaft sleeve, and the connecting ear is connected to one end of the connecting frame connection, the other end of the connecting frame is fixedly connected to the connection plate and then supported on the bottom of the water. The center of the connection plate is a shaft part, and several hydraulic propulsion mechanisms are evenly arranged on the circumference of the connection plate around the circumference of the shaft part. The propulsion mechanism can lock or loosen the shaft parts. The device of the invention can ensure that each hydraulic propulsion mechanism exerts sufficient locking force on the shaft parts, and provides a guarantee for realizing the locking of large butt joint shaft parts with different diameters underwater.

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...
