As shown in FIG. 1 , a wave-current coupled power generation device of the present invention includes a floating body 4 , a floating body support member 3 , a tidal flow deflector 2 and a wave deflector 5 .

As shown in FIG. 2 , the buoyant body 4 is connected to the flow deflector 2 through its buoyant body support member 3 arranged below the buoyant body 4 . The flow deflector 2 is composed of two parts: an acceleration section 16 and an inlet section. The inlet section is a flared structure to facilitate the flow of the current. The acceleration section 16 is a regular octagonal column structure. A wave inlet 17 is correspondingly provided on the side wall of the flow deflector 2 .

There are two wave deflectors 5, which are symmetrically arranged on both sides of the acceleration section 16 of the tidal current deflector 2, and the wave deflector 5 is tangent to the acceleration section 16 of the tidal current deflector 2 at a certain angle, and the waves The wind deflector 5 is preferably arranged vertically, and the wave deflector 5 has upper and lower openings, and the opening is flared to facilitate the entry of waves. The wave deflector 5 is a square column structure, and the middle part is provided with Open slot 18, the shape of the open slot 18 is matched with the positive octagonal shape of the flow guide cover. The adjacent three sides of the side column match, so that the opening slot 18 is clamped on the regular octagonal column of the flow diversion cover 2 . The opening groove 18 corresponds to the wave inlet 17, and the wave deflector 5 is tangent to the acceleration section of the tidal current deflector 2 through the opening groove 18. As shown in Figure 6.

As shown in Figure 3, there are four wave inlets 17, which are symmetrically arranged on the four oblique surfaces of the regular octagonal column of the tidal flow guide 2. After passing through the wave deflector 5 , it enters into the tidal current deflector 2 through the wave inlet 17 of the tidal current deflector 2 .

As shown in Figure 2, the wave inlets 17 are provided with baffles 9, the baffles 9 are arranged in the acceleration section 16 of the tidal flow deflector 2, and the baffles 9 are slightly larger than the wave inlets 17, thereby preventing the tide able to leak out.

As shown in Figure 4, a turbine 10 is installed in the flow deflector 2, and the turbine 10 is a horizontal turbine consisting of a flange 14, blades 13 and a main shaft 15, and the blades 13 are calculated and tested. The number of blades 13 is evenly distributed on the flange plate 14 to maximize energy absorption. The main shaft 15 is fixed on the flange plate 14, and the main shaft 15 passes through the side wall of the flow deflector 2 and the external motor 8 shaft connection. The motor 8 is placed in the motor box 6 .

As shown in Figure 5, the tail rudder 7 is installed at the end of the acceleration section 16 of the current flow deflector 2, which can make the whole device change direction with the trend of the tide twice a day, thereby reducing the setting of a current flow deflector, and achieve the same absorption effect.
