Specifically, the one-way mechanism 7 is further provided with an adjusting housing 71, and in some special application scenarios, the output shaft 77 or the input shaft 78 can be adjusted by manually rotating the adjusting housing 71 to meet maintenance or other requirements.
Further, when the folding and unfolding mechanism 5 drives the input shaft 78 to rotate clockwise around the axis through the rotating block 6, the input shaft gear 72 simultaneously drives the first output gear 74 and the second output gear 75 to rotate counterclockwise and the second output gear 75 drives the output shaft 77 to rotate counterclockwise around the axis through the first one-way bearing 76; when the folding and unfolding mechanism 5 drives the input shaft 78 to rotate counterclockwise around the axis through the rotating block 6, the input shaft gear 72 simultaneously drives the first output gear 74 and the second output gear 75 to rotate clockwise, the first output gear 74 drives the output shaft 77 to rotate clockwise around the axis through the second one-way bearing 79, and the output shaft 77 is in driving connection with the power generation mechanism to further realize power generation of the power generation mechanism.
Taking the embodiment 2 as an example, the wave energy conversion principle is as follows:

When the input shaft rotates anticlockwise, the input shaft drives the front end shaft sleeve 81 to rotate anticlockwise, the first small one-way bearing 89 drives the second transmission shaft 86 to rotate anticlockwise, the second transmission shaft 86 drives the second small one-way bearing 810 to drive the central wheel 811 to rotate anticlockwise, the rear end shaft sleeve 82 rotates clockwise through gear train transmission, reverse rotation of the input shaft and the output shaft is achieved, and therefore motion of the output shaft is one-way rotation. The output shaft is connected with the direct current generator 14, so that the direct current generator 14 generates power for the robot to use, and wave energy power generation is realized.
Taking the embodiment 2 as an example, the process of contracting the folding and unfolding mechanism when the aircraft is in navigation is as follows:
as shown in fig. 10, the stepping motor 16 is connected to the lead screw 13, the baffle nut 20 can move along the lead screw 13, the baffle nut 20 drives the fixedly connected baffle 15 to move, the baffle 15 is connected to the sliding hinge 17 through the thrust bearing 22, the sliding hinge 17 can rotate around the cylindrical guide rail 12, and can also move along the lead screw 13 along with the baffle nut 20, so as to form a cylindrical pair. The stepping motor 16 drives the lead screw 13 to rotate, drives the baffle nut 20 to move, and finally drives the sliding hinge 17 to move along the guide rail 12, and when the sliding hinge 17 moves downwards along the guide rail 12, the folding and unfolding mechanism 5 is contracted to the shape shown in fig. 4.
Taking embodiment 3 as an example, the wave energy conversion principle is as follows:
the unfolded folding and unfolding mechanism 5 is excited by waves to generate reciprocating swing, the rotating block 6 and the sliding hinge 17 rotate in a reciprocating mode along with the folding and unfolding mechanism 5, and the rotating block 6 is connected with an input shaft of the one-way mechanism 7. As shown in fig. 8, when the input shaft 78 drives the input shaft gear 72 to rotate clockwise, the input shaft gear 72 rotates clockwise, so as to drive the first output gear 74 to rotate counterclockwise; since the input shaft gear 72 is engaged with the intermediate transmission gear and the intermediate transmission gear 73 is engaged with the second output gear 75, the intermediate transmission gear 73 rotates counterclockwise, the second output gear 75 rotates clockwise, and the first output gear 74 and the second output gear 75 rotate in opposite directions and are both connected to the output shaft 77 through the one-way bearing. Therefore, the motion of the output shaft 77 is a unidirectional rotation, so that the direct current generator 14 is unidirectional in rotation, and wave energy power generation is realized.
Taking the embodiment 3 as an example, the process of contracting the folding and unfolding mechanism 5 when the aircraft is in navigation is as follows:
as shown in fig. 11, the stepping motor 14 is connected to the lead screw crank 8, and the crank 8 drives the connecting rod 9 to move, so as to push the slider 10 to drive the sliding hinge 17 to move on the sliding rail. When the slide block 10 moves upwards along the slide rail, the folding and unfolding mechanism 5 is unfolded to be in the state shown in fig. 6, 7 and 11, and can capture energy on the wave surface; when the slide block 10 moves downwards along the slide rail, the folding and unfolding mechanism 5 is contracted as shown in fig. 4, and the contracted folding and unfolding mechanism 5 reduces the navigation resistance of the robot aircraft and improves the utilization efficiency of energy.
