[0002] The sustainable use of marine resources and the development of clean energy are increasingly valued. At present, the use of mechanical energy of ocean waves to convert into electrical energy has become a cutting-edge technology. In the face of global freshwater shortages, seawater treatment and desalination technology has also become crucial. Renewable clean energy technologies such as solar energy and wind energy have been widely used in energy islands, promoting sustainable energy development and promoting the integrated application of seawater desalination and other environmental protection technologies.

[0003] In traditional revetment structures, wave-breaking piles are mainly used to mitigate the impact of waves on revetments and protect the stability of the coastline. However, in the existing technology, the functions of these wave-breaking piles are relatively single, and their location advantages are not fully utilized. Existing revetment technology has made significant progress in protection and environmental protection, but the design of revetment structures mainly focuses on wave protection and impact resistance, while ignoring the use of marine energy resources and failing to fully utilize their potential energy production functions.

[0004] In order to meet the growing energy demand and protect the marine environment, new shore protection devices with both wave energy generation and seawater desalination auxiliary functions are urgently needed to provide innovative solutions for the sustainable development of the marine environment.

[0041] The bank protection device of this embodiment with two power generation forms and seawater desalination auxiliary functions includes: a bank protection body 100 and wave-breaking piles.

[0042] The wave-breaking pile includes a floating body 1, a wave energy conversion chamber 2, a first generator 3 and a transmission mechanism. The floating body 1 is arranged in the sea area near the revetment body 100, floats on the sea surface and moves up and down with the waves on the sea surface, and plays the role of capturing wave energy. The wave energy conversion chamber 2 is arranged near the floating body 1, and the first generator 3 is arranged in the wave energy conversion chamber 2. The floating body 1 and the first generator 3 are connected through a transmission mechanism, and the power transmission mechanism converts the wave energy captured by the floating body 1 into kinetic energy and transmits it to the first generator 3, driving the first generator 3 to operate and generate electricity. The power generated by the first generator 3 is incorporated into the power grid of the energy island 200 to supply power to the seawater desalination system on the energy island 200. Preferably, the first generator 3 is connected to the power grid of the energy island 200 through a cable 13 buried in the foundation of the revetment body 100 to achieve power output and grid connection.

[0043] A filter screen 7, a water reservoir 6, a water outlet channel 4 and a turbine 5 are provided inside the revetment body 100. The filter screen 7 is laid on the protective layer of the revetment body 100 near the sea area. The filter screen 7 is laid on the protective layer of the revetment body 100 near the sea area as the entrance of the water reservoir 6. The seawater is initially filtered through the filter screen 7 to achieve coarse filtration, and then enters the water reservoir 6. The water reservoir 6 is located at a high position inside the revetment body 100. The water reservoir 6 is used to collect and regulate the initially purified seawater. A water outlet 61 is provided at the top of the water reservoir 6. The water outlet 61 is connected to the top of the water outlet channel 4. A drain 41 is provided at the bottom of the water outlet channel 4. The water outlet 61 at the top of the water reservoir 6 is higher than the drain 41 at the bottom of the water outlet channel 4. The drain 41 of the water outlet channel 4 is connected to the seawater desalination system of the energy island 200. The water outlet channel 4 is preferably a downhill channel. The turbine 5 is provided in the water outlet channel 4 and connected to the second generator. The water turbine 5 is preferably arranged at the bottom of the water outlet channel 4. The preliminarily purified seawater stored in the water reservoir 6 can enter the top of the water outlet channel 4 through the water outlet 61 at the top, and flow to the bottom of the water outlet channel 4 under the action of gravity and finally flow from the drain 41 to the seawater desalination system of the energy island 200. At the same time, when flowing through the water turbine 5 arranged in the water outlet channel 4, the water turbine 5 is driven to operate and the second generator is driven to generate electricity. The power generated by the second generator is incorporated into the power grid of the energy island 200 to supply power to the seawater desalination system on the energy island 200. Preferably, the second generator is connected to the power grid of the energy island 200 through the cable 13 buried in the foundation of the revetment body 100 to achieve power output and grid connection.

The power generation of the first generator 3 and the second generator are both incorporated into the power grid of the energy island 200, forming a synergistic power generation system with two forms of power generation, which effectively converts the mechanical energy of the waves into usable clean energy, and provides continuous power support for the seawater desalination process of the energy island 200. At the same time, the bank protection device of this embodiment also has a desalination auxiliary function. The filter screen 7 provides preliminary filtration, effectively reducing particulate matter and solid particles in the seawater entering the water reservoir 6, so that the water reservoir 6 provides a preliminary clean water source for subsequent desalination treatment. Therefore, the bank protection device of this embodiment can not only efficiently capture wave energy and provide preliminary filtration of seawater, but also realize the utilization of gravitational potential energy through the turbine 5 system, which can provide clean water and renewable energy for desalination treatment and the operation of the energy island 200. This multifunctional integrated design not only assists in wave elimination and bank protection, and ensures the stability of the near-shore ecosystem, but also provides engineering use value with multi-objective development and multi-purpose, and provides innovative solutions for the sustainable development of the marine environment.

The floating body 1 is connected to the hydraulic cylinder 8 through a connecting rod 11 to achieve a response to the up and down movement of the waves, and convert the up and down movement of the waves into the reciprocating movement of the piston of the hydraulic cylinder 8. The hydraulic cylinder 8 and the hydraulic pump 9 are connected by an oil pipe, and the mechanical movement of the piston of the hydraulic cylinder 8 is converted into high-pressure hydraulic oil, which is pumped by the hydraulic pump 9. The hydraulic pump 9 and the hydraulic motor 10 are connected by an oil pipe, and the hydraulic oil is sent to the hydraulic motor 10 through the hydraulic pump 9 and drives the hydraulic motor 10 to rotate, converting the flow of hydraulic oil into rotational power. The hydraulic motor 10 is connected to the first generator 3 through a coupling, and the rotation of the hydraulic motor 10 drives the first generator 3 to rotate and generate electricity. The hydraulic transmission mechanism composed of the hydraulic cylinder 8, the hydraulic pump 9 and the hydraulic motor 10 can efficiently realize the conversion of the wave energy captured by the floating body 1 into kinetic energy and transmit it to the first generator 3, driving the first generator 3 to operate and generate electricity.

[0046] Furthermore, the transmission mechanism also includes an oil cylinder 12. The oil pipe connecting the hydraulic pump 9 and the hydraulic motor 10 is connected to the oil cylinder 12.
