the wave energy collecting device (4) comprises an oscillating floater (401), a rack (402), a first overrunning clutch (404), a first reversing ratchet mechanism (405) and a cylindrical gear (407), wherein the oscillating floater (401) is arranged below the base platform (102), a connecting rod of the oscillating floater passes through the base platform (102) from bottom to top, the rack (402) is arranged at the upper end of the connecting rod, the rack (402) is meshed with the cylindrical gear (407), and the cylindrical gear (407) is connected with the first reversing ratchet mechanism (405) through a first transmission shaft (403);
the tidal current energy collection device (5) comprises a sleeve (501), a first bevel gear set (502), an impeller (503), a second transmission shaft (504), a second reversing ratchet mechanism (505) and a second overrun clutch (506), wherein the sleeve (501) is arranged below the base platform (102), the impeller (503) is fixed in the sleeve (501), the opening direction of the sleeve (501) is perpendicular to the plane surface of the fan platform, and the openings at two ends of the sleeve (501) are large and small and are in a symmetrical structure, so that the direction can be changed along with tidal current; the impeller (503) is connected with a second transmission shaft (504) through a first bevel gear group (502), and the second transmission shaft (504) penetrates through the base platform (102) from bottom to top and is connected with a second reversing ratchet mechanism (505);
the first reversing ratchet mechanism (405) and the second reversing ratchet mechanism (505) have the same structure, and the first overrunning clutch (404) and the second overrunning clutch (506) have the same structure; the first reversing ratchet mechanism (405) and the second reversing ratchet mechanism (505) are respectively connected with the first overrunning clutch (404) and the second overrunning clutch (506), and the first overrunning clutch (404) and the second overrunning clutch (506) are coupled together through a second bevel gear set (603).
The working principle is as follows: the oscillating floater (401) floats on the sea surface, and under the action of wave force, the oscillating floater (401) vibrates up and down so as to drive the rack (402) to reciprocate up and down; since the rack (402) is meshed with the cylindrical gear (407), the cylindrical gear (407) converts up-and-down reciprocating motion into reciprocating rotary motion of the first transmission shaft 403, and the first reversing ratchet mechanism (405) converts bidirectional rotary motion into unidirectional rotary motion;
the impeller (503) rotates under the action of tide to convert the tide energy into mechanical energy; the impeller (503) rotates to drive a vertically arranged second transmission shaft (504) to rotate through the first bevel gear set (502), and the flow of current drives the impeller (503) to rotate with reciprocation, so that the reciprocation of the second transmission shaft (504) is converted into unidirectional rotation by the second reversing ratchet mechanism (505);

The wave energy collecting device (4) and the tidal current energy collecting device (5) are coupled together through a second bevel gear set (603) (the first bevel gear set (502) and the second bevel gear set (603) are formed by mutually coupling 3 bevel pinions (601B)), so that one set of speed increaser (2) and one set of generator (3) are shared, and meanwhile, the overrunning clutch ensures that the two sets of energy collecting devices are not interfered with each other in the transmission process, and the generators are driven to generate power in a complementary mode; in addition, by arranging the wave energy and tidal current energy collecting devices in an array, the utilization rate of the platform can be further improved, and the power generation scale is improved.
