DETAILED DESCRIPTION

[0017] It should be noted that, in this embodiment, the term "front" refers to close to sea level, and "rear" refers to away from sea level; the terms "inside", "outside", "left", "right", etc. are all described in accordance with the accompanying drawings, and ordinary technicians in this field should understand them in accordance with the technical solution of the present invention.

[0018] The following is combined with Figure 1-3 The present invention is further described in detail: a wave surge power generation device comprises a base plate body 1, a mobile body, and a generator set; the base plate body 1 is fixed on the coast embankment; the mobile body is confined in the base plate body 1 and can move along the length direction of the base plate body 1; the mobile body itself has a certain weight, and in the initial state, the mobile body is close to the sea level, and under the upward and forward impact of the wave surge, the mobile body moves away from the sea level, driving the generator set to generate electricity; after the wave surge recedes, since the base plate body and the coast embankment have a certain angle, the mobile body moves toward the sea level, also driving the generator set to generate electricity; this is repeated, thereby extending the power generation time.

[0019] Specifically, Figure 1-3 As shown, in this embodiment, the moving body is a hull frame 17, which includes a bottom plate, a baffle and an intermediate plate 19; there are two baffles, which are respectively installed on the left and right sides of the bottom plate, and the intermediate plate is installed in the hull frame 17, and one side of the intermediate plate 19 is opposite to the direction of wave surge, and its two ends are respectively fixed to the left and right baffles; as a preferred implementation scheme of this embodiment, there are two intermediate plates 19, which are arranged in the hull frame 17 front and back, and the height of the intermediate plate 19 away from the sea level is higher than the height of the intermediate plate 19 close to the sea level.

[0020] There is a certain angle between the bottom plate body 1 and the sea level, which includes a bottom plate and a groove; the bottom plate is placed on the coastal embankment. In the present embodiment, the coastal embankment and the sea level form an angle of 145°. Of course, it is not limited to this angle, and the weight of the hull frame 17 can be set according to the specific conditions of the coastal embankment, as long as the hull frame 17 can move back and forth in the bottom plate body 1; the groove is L-shaped, relatively arranged on both sides of the length direction of the bottom plate, and one end thereof extends out of the end of the bottom plate; a space for accommodating the movement of the hull frame 17 is formed between the two grooves, and both ends of the hull frame 17 are located in the groove; when in use, the bottom plate body 1 is placed at an angle attached to the coastal embankment along the length direction and fixed to the coastal embankment by screws 11.

[0021] As a preferred implementation mode of this embodiment, rollers 15 are installed at both ends of the hull frame 17, and the rollers 15 are adapted to the groove. In this embodiment, the number of rollers 15 is 4, which are installed opposite to each other in pairs. Under the action of external force, the hull frame 17 moves along the length direction of the groove. In order to prevent the hull frame 17 from running out of the groove during movement, shaft sleeves 14 are respectively installed at both ends of the hull frame 17. The shaft sleeves 14 are located at the edge of the groove as limit members. In this embodiment, the number of shaft sleeves 14 is 4, which are installed opposite to each other in pairs. During the movement of the hull frame 17, the shaft sleeves 14 rotate synchronously, thereby reducing friction.

[0022] The generator set includes a generator 4, a flywheel, a rotor, a large wheel and a belt. The generator 4 is installed at one end of the bottom plate body 1 away from the sea level and meshes with the large wheel through gears. The flywheel and the rotor are respectively arranged at both ends of the length direction of the bottom plate body 1. The flywheel, the rotor and the large wheel are all installed on the bottom plate body 1 through the connecting shaft 2. The belt is installed on the flywheel and the rotor, and the two ends thereof are respectively connected to the two sides of the hull frame 17; under the upward and forward impact of the wave surge, the hull frame 17 moves along the length direction of the bottom plate body 1 in the direction away from the sea level, and the belt drives the flywheel to rotate, thereby driving the large wheel to rotate through the connecting shaft to achieve power generation; after the wave surge recedes, the hull frame 17 moves along the length direction of the bottom plate body 1 toward the sea level, and the belt drives the flywheel to rotate, thereby driving the large wheel to rotate through the connecting shaft to achieve power generation.

[0023] As a preferred implementation scheme of this embodiment, there are two flywheels, namely flywheel 6 and flywheel 7. Flywheel 6 and flywheel 7 are arranged at the end of the base plate body 1 away from the sea level and installed on the connecting shaft 2. The two ends of the connecting shaft 2 are respectively installed in bearings 3 and bearing 9. Bearings 3 and bearings 9 are respectively installed on the upper surface of the groove of the base plate body 1, and are just located above the groove extending out of the base plate; the rotating wheel 16 is arranged at the end of the base plate body 1 close to the sea level; the belt includes belt A10 and belt B18, one end of belt A10 is connected to the side of the hull frame 17 away from the sea level through spring A13, and the other end passes through flywheel 7 and rotating wheel 16 in sequence to be connected to the other side of the hull frame 17; one end of belt B18 is connected to belt A10 through spring B12, and the other end is connected to the side of the hull frame 17 away from the sea level; in the process of the flywheel, connecting shaft 2 and large wheel driven by the belt to rotate, the rotating wheel 16 also rotates accordingly.

[0024] As a preferred implementation mode of this embodiment, the outer diameter of the large wheel is larger than the outer diameter of the flywheel; there are two large wheels, namely large wheel 5 and large wheel 8, which are respectively located on both sides of flywheel 6 and flywheel 7, have a certain weight, and can receive energy, release energy, and store energy.

[0025] Design principle: the bottom plate body 1 is fixed to the coast with screws 11. Since the coast embankment and the sea level have a certain angle, the wave surge has a strong forward and upward force. The wave surge occurs all year round. When the wave surge reaches the coast, it releases huge energy. The hull frame 17 moves under the upward and forward impact of the wave surge, driving the belt A10 to pull the flywheel 7 to rotate, and then the large wheel 5 and the large wheel 8 on the connecting shaft 2 rotate. Because the large wheel is engaged with the generator through the gear, the generator generates electricity; after the wave surge recedes, because the hull frame 17 has a certain weight, it moves downward, and the belt B18 drives the flywheel 6 to rotate the large wheel on the connecting shaft 2, so that the generator generates electricity; during the up and down movement of the hull frame 17, the spring A13 and the spring B12 drive the belt to recover; in this way, the rotation is cyclical, and at the same time, because the large wheel has a certain amount of energy storage, the generator can generate electricity for a long time.

[0026] The above embodiments are only preferred implementations of the present invention and do not constitute a limitation of the present invention. Any extensions and modifications made by ordinary technicians in this field without departing from the principle of the present invention should be included in the protection scope of the present invention.
