Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0032] figure 1 As shown, the bionic underwater glider with fluctuating fins provided by the present invention has a body consisting of a pressure-resistant outer cylinder 2, a head end cover 21, and a tail end cover 11. on an end cap. The undulating fin device is connected to the drive rod 5 by the waterproof motor assembly 4 to clamp the flexible film 6. A pair of undulating fin devices are connected to the hoop 9 by the motor beam 3, and the other pair of flat wings 10 are perpendicular to the undul...

Abstract

The invention provides a bionic underwater glider with undulatory fins. The bionic underwater glider comprises a pressure-resistant outer cylinder, a head end cover and a tail end cover, a flow inletsection and a flow outlet section are installed on the head end cover and the tail end cover correspondingly, and a pair of undulatory fin devices is mounted on the two opposite sides of the tail portion of the pressure-resistant outer cylinder. The undulatory fin devices create sinusoidal waves so as to generate propulsion for a machine body, and when the motion direction, the amplitude and/or the frequency of the sinusoidal waves is changed, the propulsion produced by the undulatory fins is also changed so as to control the machine body to move. The bionic underwater glider with the undulatory fins solves the technical problem that a traditional underwater glider is in lack of a power source and effective communication means, so that the mobility and stability under water are poor.

Description

technical field [0001] The invention relates to a bionic underwater glider with fluctuating fins. Background technique [0002] The ocean is the second largest strategic space after the land, rich in various minerals and biological resources, and is the most realistic and potential development space at present. However, our country has a vast territory, with a long coastline in the southeast, reaching 18,000 kilometers, and a sea area close to 4.7 million square kilometers. Therefore, in-depth exploration of the ocean has become an important development direction. Underwater vehicles have become an important tool for exploring and developing marine resources in a complex marine environment, and its structure and control methods are the key to ensuring its autonomous, stable and efficient operation. [0003] At present, the widely used underwater vehicles are mainly divided into two types: manned and unmanned, and unmanned submersibles are favored due to their high cost perf...
