Problems solved by technology

Therefore, this method can only be effective in partial and small-scale strokes, and cannot play a role in full strokes
In addition, the two split screws need to ensure the same angular velocity of rotation and no axial interaction force between the two, otherwise there will be two screws facing each other and self-locking stuck

Embodiment Construction

[0113] Below in conjunction with accompanying drawing, the technical scheme of the present invention is described in further detail:

[0114] The present invention may be embodied in many different forms and should not be considered limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, components are exaggerated for clarity.

[0115] The difficulty of dynamic sealing under high water pressure is the bottleneck for the reliable release of electromagnetic motor-driven releasers, and the piezoelectric drive technology represented by ultrasonic motors is one of the most ideal driving methods to deal with harsh environments such as deep-sea high water pressure, low temperature and strong corrosion. one. In order to meet the requirements of self-locking when there is no command, and detachment after rece...

Abstract

The invention provides a piezoelectric-driven deep-sea release system and a working method thereof. The piezoelectric-driven deep-sea release system includes a floating body, a detector, a piezoelectric releaser, a connecting bearing, first to fourth connecting rods, and an anchoring weight. The piezoelectric releaser includes a piezoelectric transducer and a mover. The piezoelectric transducer and the mover are matched with each other through threads. The floating body ensures that the screw fitting area between the piezoelectric transducer and the mover is in close contact, and the thread for driving the piezoelectric transducer can separate the mover and the piezoelectric transducer by means of frictional force. After separation, the probe is towed to the sea surface by a floating body. The present invention is integrated into the application scene, uses the traction floating body to apply the pre-pressure, is simple and reliable, and can be applied to the acquisition of marine information.

Description

technical field [0001] The invention relates to the field of piezoelectric-driven deep-sea release, in particular to a piezoelectric-driven deep-sea release system and a working method thereof. Background technique [0002] The deep-sea acoustic releaser is a powerful tool for the acquisition of marine information. It uses counterweights and floating balls to adjust the buoyancy and gravitational relationship of detection instruments and equipment in the water, and completes the release, positioning and recovery of detection instruments and equipment. The detection instruments and equipment deployed by the deep-sea acoustic releaser can obtain information such as the geographical environment, topographic characteristics, and meteorological conditions of the sea area in a fixed-point, long-term, continuous and hidden way. [0003] The existing electromagnetic motor-driven deep-sea releasers have many problems. The electromagnetic motor speed is too high to directly drive the ...
