[0004] The movement process and mechanism of the wave energy glider underwater gliding machine make the wave energy glider move up and down with the waves, and the hydrofoil swings to the upper (lower) end of the hollow slot, and hardly uses the undulating motion of the wave to convert it into a forward direction. power, which causes the wave energy glider to have a work blind area when it is driven by waves in each work cycle, especially in the 0 to 1 sea conditions, the wave height is very small, and the underwater gliding machine of the wave energy glider is sensitive to weak wave height waves. The energy conversion efficiency of the platform will be very low, and the power performance of the platform in this environment is very poor
The structural characteristics and motion mechanism of the underwater glider will reduce the utilization efficiency of wave energy, and at the same time reduce the dynamic performance index of the wave energy glider platform under severe sea conditions

Description
technical field [0001] The invention relates to a propeller propulsion device, in particular to a propeller propulsion device driven by wave energy and an underwater gliding machine driven by the device. Background technique [0002] The large-scale and long-term characteristics of ocean monitoring, the harsh operating environment and expensive observation costs force humans to develop a low-cost autonomous operating platform that is not limited by energy sources and can operate in a large area for a long time without maintenance, so as to extend human understanding of the world's oceans. tentacles. At present, the wave energy gliders emerging in the world provide innovative ideas for ocean observation technology. The platform cleverly utilizes marine environmental energy to realize long-term and large-range observation operations, and exchanges instructions and data between satellites and monitoring base stations. It has become the basic platform for the construction of oc...
