[21] As shown in FIG. 1 and FIG. 2, a wave flow coupled power-generating device comprises a horizontally-arranged tide flow guide cover 1 and a vertically-arranged wave flow guide cover 2, wherein the tide flow guide cover and the wave flow guide cover are both in a hollow cylinder shape with two through ends. The bottom of the wave flow guide cover 2 is vertically connected to the middle part of the tide flow guide cover 1, and the wave flow guide cover 2 and the tide flow guide cover 1 are connected. The diameter of the head of the tide flow guide cover 1 is larger than that of the tail of the tide flow guide cover 1, and the diameter of the top of the wave flow guide cover 2 is larger than that of the bottom of the wave flow guide cover 2, and the tide flow guide cover 1 and the wave flow guide cover 2 are both in a bell mouth shape, so that the flow guide effect can be achieved, and tide energy and wave energy can be better absorbed.
[22] A bearing 3 capable of rotating relative to the wave flow guide cover 2 sleeves the part, close to the top of the wave flow guide cover 2, of the wave flow guide cover 2, and a pair of floaters 5 connected with the bearing 3 through connecting rods 4 are symmetrically arranged on the two sides of the wave flow guide cover 2, so that the whole device can float in water to absorb the tide energy and the wave energy through the two floaters 5.
[23] The tail of the tide flow guide cover 1 is connected with the tail vane 6, and the tail vane 6 mainly plays a role in steering balance. As shown in FIG. 3, a triangular support 3 connected with the circumferential edge of the tide flow guide cover 1 is arranged at the tail of the tide flow guide cover 1, and the tail vane 6 is connected with the central point of the triangular support 9 through a connecting rod 10.
[241 As shown in FIG. 4 and FIG. 5, the tail vane 6 specifically comprises a fixed part 61 and a movable part 62 which are connected front and back. The tail of the cross section of the fixed part 61 is a V-shaped notch 64 which is sunken forwards, the head of the cross section of the movable part 62 is a V-shaped bulge 65 which protrudes forwards, and the tip of the V-shaped bulge 65 extends into the V-shaped notch 64 and is connected with the tip of the V-shaped notch 64 through a rotating shaft 63. Moreover, the included angle of the tip of the V-shaped bulge 65 is smaller than the included angle of the tip of the V-shaped notch 64, and the movable part 62 can rotate within the opening range of the V-shaped notch 64 along the rotating shaft 63.
[25] The tail vane with the structure has the advantages that when water flow rushes from the side face, the movable part can move in a small range around the rotating shaft under the impact of the water flow, so that the blocking area of the movable part to the water flow is increased, the impact force of the water flow to the tail vane is increased, and then the movable part drives the fixed part to quickly rotate to a water inlet of the tide flow guide cover, namely a horn mouth of the water inlet faces the water flow impact direction.
[26] An impeller 7 capable of rotating in the axial direction is arranged at the part, close to the tail of the tide flow guide cover 1, in the tide flow guide cover 1, a power generator 8 is fixed outside the tide flow guide cover 1, one end of the rotating shaft of the impeller 7 extends out of the tide flow guide cover 1, gears 11 are arranged at the end of the rotating shaft and the input end of the power generator 8, the end of the rotating shaft 8 and the input end of the power generator 8 are meshed and linked through a gear belt 12 and the gears 11, and the power generator 8 is driven through rotation of the impeller 7 for power generation.
[27] The impeller 7 can specifically adopt the structure as shown in FIG. 6, blades are evenly distributed on the periphery of the impeller, and impact of water flow on the blades drives a central shaft to rotate through connected rib plates.
[28] When the whole device is placed in the sea, the device can float in the sea water under the action of the two floaters.
[29] When tide generated by the movement of sea water impacts the device, the tail vane can drive the device to rotate around the bearing until the direction of the tail vane is the same as the water flow direction of sea water due to the fact that the area of the tail vane is large and the resistance borne by the sea water is larger than the resistance received by other parts except the floaters. The tail vane can drive the tide flow guide cover to adapt to the water flow direction, so that the water inlet of the tide flow guide cover always faces the water flow direction, and more sea water is collected.
[30] When the sea water enters the wave flow guide cover through fluctuation of waves generated on the sea surface, wave flow and tide flow enter the device together and are coupled, and the coupled water flow impacts the impeller to enable the impeller to rotate. The impeller rotates to drive the input end of the power generator to rotate through the gear belt, so that the power generator generates electricity.
[31] The device can self-adapt to the water flow direction, the tide flow guide cover can self-adapt to the tide direction and collect more tide energy, meanwhile, the tide flow and the wave flow can be coupled to jointly act on the impeller, the tide energy and the wave energy are converted into electric energy, and better economic benefits are obtained.
