[0015] Hereinafter, the embodiments of the present invention will be described in more detail with reference to the drawings and examples. The following examples are used to explain the present invention, but are not intended to limit the scope of the present invention.

[0016] In the description of the present invention, unless otherwise clearly defined or limited, the terms "connection" and "coupling" should be understood in a broad sense, and may refer to, for example, a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or an indirect connection via an intermediate medium. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0017] As shown in Figures 1 to 5, this embodiment is a power generation device that utilizes ocean wave energy, and includes a plurality of independent ocean wave energy collection mechanisms 1, which convert ocean wave energy into mechanical energy and then compress air using the mechanical energy. The plurality of ocean wave energy collection mechanisms 1 are installed along the coast via a bottom support frame 9, to avoid the entire ocean wave energy collection mechanism 1 being too close to seawater and causing surface corrosion, which would make maintenance difficult and shorten its service life. The plurality of ocean wave energy collection mechanisms 1 are connected to a generator 8 of an onshore power plant via a pressurizing device, which improves the power generation efficiency of the generator 8 by pressurizing the gas, thereby forming a large-scale power generation. The pressurizing device includes a primary pressurizing device, a secondary pressurizing device and a tertiary pressurizing device. The primary pressurizing device is divided into a plurality of groups, and each group has The system includes a primary pressure tank 2 and a primary air compressor 3 connected in series via piping, the inlet of the primary pressure tank 2 connected to a pipe connecting the outlets of multiple ocean wave energy harvesting mechanisms 1, and gas is collected via the primary air compressor 3 and transported through the piping to a secondary pressurization device on land, the secondary pressurization device including a secondary pressure tank 4 and a secondary air compressor 5, the inlet of the secondary pressure tank 4 connected to a pipe connecting the multiple primary air compressors 3, and air is transported via the secondary air compressor 5 to a tertiary pressurization device at the power plant, the tertiary pressurization device including a tertiary pressure tank 6, the tertiary pressure tank 6 being buried underground and having an inlet connected to the pipe connecting the multiple secondary air compressors 5, the outlet of the tertiary pressure tank 6 being connected to a generator 8, which is also connected to the generator 8 via a pipe. The step-by-step pressurization method increases the pressure of the gas, enabling the generator 8 to generate large amounts of electricity.

[0018] Furthermore, a heater 7 is connected between the tertiary pressure tank 6 and the generator 8. By heating the gas output from the tertiary pressure tank 6, the gas expands, further increasing the air pressure and improving the power generation efficiency of the generator 8.

[0019] Specifically, the generator 8 is a turbine generator, and is internally driven by a steam turbine, and the intake port of the steam turbine is connected to the exhaust port of the heater 7 by a pipe.

[0020] The primary air compressor 3 has the same structure as the secondary air compressor 5 and is powered by an air motor 11. The air intake of the air motor 11 of the primary air compressor 3 is connected to the outlet of the primary pressure tank 2, while the air intake of the air motor 11 of the secondary air compressor 5 is connected to the outlet of the secondary pressure tank 4, and the outlet of the air motor 11 discharges air to the outside. The primary air compressor 3 sends gas with a high humidity and salt content to the air motor, which operates the air motor and drives the air compressor to suck in land air and send it to the secondary pressure tank 4 without requiring electricity. The secondary air compressor 5 then circulates the gas, significantly reducing the humidity and salt content, thereby preventing corrosion of subsequent equipment and reducing maintenance costs.

[0021] Furthermore, the ocean wave energy harvesting mechanism 1 includes a pneumatic cylinder 101, a piston 102, a piston rod 103, an intake nozzle 104, an exhaust nozzle 105, a check valve 106, an air vent 107, a lever 108, a lever rotation shaft 109, and a wave breaker 110. The pneumatic cylinder 101 is fixed at an incline above the support frame 9, a piston 102 is provided inside the pneumatic cylinder 101, a piston rod 103 is fixed vertically to the outside of the piston 102, and the intake nozzle 104 is fixed to the circumferential bottom of the pneumatic cylinder 101, and a reverse A stop valve 106 allows gas to flow in but not out, an intake nozzle 104 is fixed to the bottom of the pneumatic cylinder 101, and another check valve 106 allows gas to flow out but not in, an air vent 107 is fixed to the upper circumferential surface of the pneumatic cylinder 101, the outer end of the piston rod 103 is hingedly connected to the tip of a lever 108, the lever 108 rotates via a lever rotation shaft 109 in the middle, and a breakwater 110 is fixedly connected to the bottom end of the lever 108, and the breakwater 110 is located in seawater. The lever connection method converts ocean wave energy into mechanical energy to compress and transport gas.

[0022] A protective cover 10 fixed to a support frame 9 is attached to the exterior of the ocean wave energy harvesting mechanism 1, which reduces the impact of bad weather on the ocean wave energy harvesting mechanism 1 and reduces the frequency of later maintenance and inspection.

[0023] A hook 111 that can be connected to the lever 108 and limits the swing of the lever 108 is attached to the protective cover 10 in a position close to the lever 108. This prevents damage to the lever 108 and the breakwater 110 due to bad weather such as a hurricane.

[0024] The operating principle of this invention is as follows: Ocean waves move the piston 102 through the wave breaker 110, which compresses the gas in the pneumatic cylinder 101 and sends the gas through the exhaust nozzle 105. After the ocean waves pass, the lever 108 returns itself and the piston (102) under its own weight, cyclically compressing the gas. Thus, the ocean wave energy is converted into mechanical energy to compress the gas. The compressed gas is stored and boosted by the multiple ocean wave energy collection mechanisms 1 from the primary pressure tank 2. When the pressure reaches a certain level, the gas is converted through the onshore primary air compressor 3, and then sent to the high humidity areas along the coast. The high temperature and high salinity gas is used to power the air motor 11, allowing the primary air compressor 3 to compress the air on land and transport it to the secondary pressure tank 4, increasing the atmospheric pressure storage. The gas is then converted again by the secondary air compressor 5, and the gas further away from the shore is compressed and transported to the tertiary pressure tank 6. The entire process does not require the use of electricity, and reduces the humidity and salinity in the gas. The gas is compressed and stored multiple times, and the gas output from the tertiary pressure tank 6 is then passed through the heater 7, where it is heated and expanded, thereby playing the role of pressurization again, and the generator 8 generates electricity more efficiently.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and equivalents thereof.
