[0027] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0028] Example 1 refer to Figure 1 This embodiment provides a trumpet-shaped power generation device based on sea surge kinetic energy, comprising a flow guide structure 1, a sea surge rectification platform 2, and a power generation device 3 connected in sequence; wherein: The guide structure 1 is used to collect sea surges and guide them to the sea surge rectification platform 2; The sea surge rectifying platform 2 guides the rectified sea surge into the power generation device 3, and the power generation device 3 generates electricity using the kinetic energy of the rectified sea surge.

[0029] For ease of understanding of the present invention, now combined with Figure 1 , the principle of the present invention is explained: At the lowest tidal line, the sea surge rectifying platform 2 is fixed on the seabed. AC forms the wide end of the diversion structure, BD forms the narrow end of the diversion structure, and AB and CD form an angle (30~120°).

[0030] Since seawater is incompressible, Bernoulli's equation is the specific application of the law of conservation of energy in moving fluids. When the sea surge moves toward the shore, the instantaneous flow between AC is equal to the instantaneous flow between BD.

[0031] It can be assumed that: (i) The distance between A and C is 300 m, and the distance between B and D is 3 m.

[0032] (ii) The sea surge velocity at the wide mouth is V = 0.2 m / s, the water depth at A and C = 3 m, and the water depth at B and D = 2 m.

[0033] Then we can get: AC cross-sectional flow rate = BD cross-sectional flow rate = 300m*3m*0.2m / s=180m 3 / s.

[0034] BD cross-section flow = 180m 3 / s≈180 tons / s.

[0035] Force per square meter at BD = 180 tons / 6m 2 =30 tons / m 2 .

[0036] The BD flow rate is 30m / s.

[0037] It can be seen that when the flow velocity at the wide end is only 0.2m / s, 30 tons / m can be generated at the narrow end. 2 The force at the wide mouth and the flow rate are 30m / s, and the greater the flow rate at the wide mouth, the greater the force and flow rate at the narrow mouth. Therefore, the technology of collecting sea surges to generate electricity is feasible.

[0038] That is, the tidal phenomenon is that the sea surge moves parallel to the coast and forms white waves. After the AB side and the CD side form an angle, the movement trajectory of the sea surge changes from parallel movement to oblique movement, forming a huge surge at the BD outlet, that is, the bell mouth (narrow mouth). After being rectified by the sea surge rectification platform 2, it impacts the parallel axis water turbine blades on the power generation equipment 3. At this time, the water turbine rotates, the water turbine main shaft outputs torque, and transmits it to the generator main shaft. The rotor cuts the magnetic lines to generate ampere electricity, thereby generating electricity.
