Wave energy power generation system for underwater vehicle

Abstract

The invention relates to a wave power generation system for an underwater vehicle. The wave power generation system comprises a sealed cabin, a power generation device part, a damping buffer structure and an anchoring part, wherein the sealed cabin is arranged in an underwater vehicle shell (1) and is isolated by an isolation plate (2). The power generation device part comprises a stator 3 of a permanent magnet linear motor, a rotor (4) of the permanent magnet linear motor, a lower floating body (11), a foldable sealing pipe (9) and a telescopic device; the damping and buffering structure comprises a top damping and buffering box, at least one bottom damping and buffering box and two elastic rubber pads (17). The anchoring part comprises an anchoring chamber (13), an anchor gear (18), a roller (19), a rotating shaft (20), an anchor mouth (14), an anchor chain (15) and an anchor (16). According to the invention, the loss of captured energy can be reduced, the efficiency of the whole power generation device is improved, and the impact oscillation of moving waves on the device and the aircraft can be relieved.

Description

technical field [0001] The invention belongs to the field of wave power generation, in particular to an autonomous underwater vehicle wave energy power generation system. Background technique [0002] Autonomous underwater vehicle (AUV) is a comprehensive and advanced marine vehicle, which has extremely important strategic significance and application prospects in many fields such as marine missions and marine applications. However, its power source mainly depends on its own battery. Due to the limitation of its own size and battery capacity, the voyage time is not long and the mileage is limited. Therefore, it is particularly important and practical to study a power generation system that can continuously supply power to AUVs. Wave energy is a renewable and clean energy that contains abundant energy in the ocean, and its rational and effective use will benefit many areas of the ocean.

AI Technical Summary

Problems solved by technology

[0003] The wave power generation devices currently used in underwater vehicles are generally rotary generators with very complicated transmission and speed change mechanisms, which not only increase the complexity and volume of the device, but also increase the energy loss, making the power generation device more efficient. lower

At the same time, most of these power generation devices are not equipped with relevant structures for vibration buffering. Oscillation shocks caused by sudden wave movements will have a certain impact on the power generation device itself and the aircraft, and even directly damage the device itself under severe sea conditions.
