Problems solved by technology

[0006] In order to avoid the shortcomings of the existing technology and overcome the shortcomings of the current underwater vehicle power propulsion device, such as complex structure, high cost, and changes in vector propulsion efficiency, the present invention proposes an underwater vehicle with a low-pressure gear pump as the core component. The power propulsion device of the aircraft uses a motor to drive a low-pressure gear pump that can be turned forward and reverse, combined with the baffle block structure installed on the shell of the underwater vehicle, sprays water outside the aircraft, and uses two sets of devices to realize navigation The vector propulsion of the vehicle in the horizontal plane, the device is suitable for low speed, small underwater vehicles

Abstract

The invention discloses a low-pressure gear pump and underwater vehicle power propelling device, and relates to the field of design of a novel marine vehicle power propulsion system. The device comprises a power component, a transmission component, a low-pressure gear pump component, a baffle and stopping block component and a connecting component. Two power propelling devices are arranged in an underwater vehicle in a crossed mode, and vector propulsion of a horizontal plane is achieved through forward and reverse rotation of a gear pump and the baffle and stopping block structure. The device has the advantages that the structure is simple, the manufacturing cost is low, the noise is small, the efficiency is not changed during vector forward and reverse propulsion, and the device is suitable for low-speed and small underwater vehicles.

Description

Technical field [0001] The invention relates to the design field of a new type of marine vehicle power propulsion system, in particular to a low-pressure gear pump and an underwater vehicle power propulsion device. Background technique [0002] In the 21st century, with the development of industry, the finiteness of terrestrial resources has increasingly restricted the progress of mankind, and the abundance of marine resources has drawn man’s attention to the vast and mysterious ocean. Mankind's exploration of the ocean has continued to deepen, and a batch of equipment for the exploration and research of ocean lakes has been gradually developed. The underwater vehicle has become an important underwater operation equipment, and is widely used in the fields of inland river dyke inspection, marine structure installation and maintenance, deep-sea resource detection, and marine pipeline maintenance. [0003] The main propellers used in underwater vehicles are divided into propeller pro...
