In the marine vehicle for converting wave energy into low-frequency pitching motion to realize propulsion, during specific use, the propulsive force for sailing in waves mainly comes from the pitching motion and the heaving motion of the wave energy conversion hydrofoil 3, the motion can enable the wave energy conversion hydrofoil 3 to generate the propulsive force along the wave motion direction (longitudinal direction), and in addition, the circular motion of water mass points in the waves can also act on the wave energy conversion hydrofoil 3 to enable the wave energy conversion hydrofoil 3 to also generate vertical dynamic lifting force and propulsive force along the wave motion direction (longitudinal direction), and the marine vehicle for converting the wave energy into the low-frequency pitching motion to realize propulsion can sail with the waves under the combined action of the circular motion of the water mass points and the periodic pitching motion of the wave energy conversion hydrofoil 3. The wave energy conversion hydrofoil 3 pitch motion and heave motion come from the periodic pitch motion of the marine vehicle which converts wave energy into low-frequency pitch motion to realize propulsion, and the forming process of the periodic pitch motion can be divided into two stages, specifically as follows:
in the first stage, when the marine vehicle which converts wave energy into low-frequency pitching motion to realize propulsion sails in waves, the wave energy absorption device 1 is lifted away from the initial free liquid surface 6 (the free liquid surface 6 shown in figure 2) under the action of the waves (wave buoyancy lifts the wave energy absorption device 1, the bottom of the wave energy absorption device 1 and the channel 103 are slapped by the wave force to apply an upward force), so as to finish the wave energy absorption, and because the whole marine vehicle which converts wave energy into low-frequency pitching motion to realize propulsion does pitching motion around the gravity center 5 in the waves, when the wave energy absorption device 1 is lifted upwards by the waves, the whole marine vehicle which converts wave energy into low-frequency pitching motion to realize propulsion receives a moment in the counterclockwise direction around the gravity center 5, and the wave energy storage device 2 has a downward motion under the action of the moment, the volume of water drained when the wave energy storage tank is submerged is increased compared with that shown in the figure 2, and the wave energy storage is completed. The conversion of wave energy into low frequency pitch motion effects a counterclockwise motion of the propelled marine vehicle about the center of gravity 5 to the wave energy converting hydrofoil 3 via the vertical connecting rod 9, which also effects a counterclockwise motion about the center of gravity 5.
In the second stage, the wave lifting force applied to the wave energy absorption device 1 disappears due to the continuous wave motion, and the wave energy absorption device 1 lifted away from the initial free liquid level 6 starts to move downwards under the action of the downward gravity and fall back to the position of the free liquid level 6 due to the action of the gravity; along with the disappearance of the lifting force of the waves, the wave energy is converted into the low-frequency pitching motion to realize the simultaneous disappearance of the counterclockwise moment applied to the propelled marine vehicle, the static buoyancy applied to the wave energy storage device 2 is greater than the gravity, the floating motion is started until the displacement volume recovers to the initial state shown in figure 2, the release of the stored wave energy is completed, under the combined action of the upward buoyancy force applied to the wave energy storage device 2 and the downward gravity force applied to the wave energy absorption device 1, the whole marine vehicle which converts the wave energy into the low-frequency pitching motion to realize the propulsion is subjected to a clockwise moment and motion around the gravity center 5, and the marine vehicle which converts the wave energy into the low-frequency pitching motion to realize the propulsion is transmitted to the wave energy conversion hydrofoil 3 through the connecting rod to realize the clockwise motion around the gravity center 5, so that the marine vehicle also completes the clockwise motion around the gravity center 5.
Thus, under the action of the continuous wave motion, the wave energy conversion hydrofoil 3 continuously repeats the motion of the first stage and the motion of the second stage, so that the low-frequency periodic pitching motion is realized, a motion mode similar to the swinging motion of a tail fin along the plumb line direction when a dolphin swims is formed, the thrust perpendicular to the swinging direction (the thrust along the wave motion direction) is generated, forward propelling power is provided for a marine carrier, the marine carrier which converts the wave energy into the low-frequency pitching motion to realize the propulsion can sail durably by completely depending on the wave energy, and the long-range sailing of 'following the wave and flowing along' is realized.
The marine vehicle which converts wave energy into low-frequency pitching motion to realize propulsion provided by the embodiment utilizes the unavoidable pitching motion of marine floats such as ships and the like in waves, amplifies the pitching motion through reasonable float appearance design to realize the absorption and storage of wave energy, further maintains the low-frequency pitching motion in the process of releasing the wave energy, and directly drives the bionic hydrofoils to perform pitching motion through hard connection to generate the propulsion required by the navigation of the vehicle.
Due to the unique design of the marine vehicle for converting wave energy into low-frequency pitching motion to realize propulsion, the marine vehicle can withstand sea conditions of any grade, and the traditional water surface ship and aircraft (including a glider driven by wave energy) cannot normally work under the severe wind wave environment and need to enter a harbor to avoid wind waves.
It should be noted that when the marine vehicle for converting wave energy into low-frequency pitching motion to realize propulsion is placed as shown in fig. 2, the right end of the equipment compartment 4 is the foreship of the equipment compartment 4, the left end of the equipment compartment 4 is the stern of the equipment compartment 4, the right end of the square bar 303 is the front end of the square bar, and the left end of the square bar 303 is the rear end of the square bar 303.
The principle and the implementation mode of the invention are explained by applying a specific example, and the description of the embodiment is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed.
