Buffering self-electricity-generating type wave propeller

Abstract

The invention discloses a buffering self-electricity-generating type wave propeller and belongs to the field of underwater propeller designs. The buffering self-electricity-generating type wave propeller comprises a connecting device, a power device, a buffering self-electricity-generating device and an upper floating body. The buffering self-electricity-generating device is fixed at the bottom of the upper floating body. The power device is in active connection with the buffering self-electricity-generating device through the connecting device. The buffering self-electricity-generating device is composed of a transmission connecting rod, an electric energy output wire, a magnetic piston, an induction coil, limiting springs and a shell. The upper floating body makes heaving motion under stimulation of wave force, relative motion is produced between the power device and the upper floating body, and a flexible cable connecting the upper floating body with the power device produces transient tensile force and stores wave energy in a mode of elastic potential energy of the limiting springs. The transforming pattern of the wave energy is increased, the utilization efficiency of the wave energy is improved, wave impacting damage borne by a wave glider is reduced, the service life of the wave glider is prolonged, the total electricity supply amount is increased, and the requirement of the wave glider for long-endurance operation is met.

Description

technical field [0001] The invention belongs to the field of underwater propeller design, and in particular relates to a buffer self-generating wave propeller. Background technique [0002] Conventional mobile observation platforms, such as scientific research ships, unmanned boats, and underwater vehicles, generally use fuel or batteries as power sources. Due to the limited energy they carry, their endurance is relatively short, which is expensive for long-term ocean observation. High, poor economy, and easy to cause environmental pollution. Since the ocean contains extremely rich green energy, people have shown strong interest in using ocean energy as an energy source for ocean vehicles. Propelling underwater vehicles or unmanned boats, temperature difference energy propelling underwater vehicles, wind or solar energy propelling unmanned boats, wave energy propelling underwater vehicles, etc. As a new wave energy-propelled marine unmanned vehicle, the wave glider has out...
