Wave energy is generated by transferring energy to ocean through wind, appears in the form of mechanical energy, is the largest energy and better-quality energy in ocean energy, and is also very unstable energy. With the prior art, there are two main types of wave energy collection: the other is that the energy collecting device is directly contacted with seawater, and mainly comprises an Oscillating Water Column (OWC), a Raft type (Raft), a Pendulum type (Pendulum), a buoyancy Pendulum type (Oyster), a contraction wave channel type (Tapchan), a point absorption type (PointAbsorber), a Duck type (Duck) and the like. The extraction of the wave energy of the oscillating water column is the most widely applied wave energy power generation technology at present. And more oscillating water column type wave energy test power stations are in operation in China. But it has high cost and low conversion efficiency. The pendulum wave energy is energy which utilizes the fluctuation of seawater to push a pendulum plate to swing back and forth to absorb waves. The shaft of the swinging plate of the suspended swinging type wave power generation device is arranged above, and the swinging plate swings below, so that the suspended swinging type wave power generation device is called as a pendulum. Although the suspended pendulum type device is simple, its conversion efficiency is low. The raft type wave energy conversion device is composed of a raft body, a hinged chain and a hydraulic system, the raft type wave energy conversion device is arranged along the wave direction, the raft body moves along with the waves, and the wave energy is converted into mechanical energy for movement of the raft body. However, the raft-type wave energy conversion device is expensive due to the longer wavelength of the sea waves. The second wave energy collecting device is characterized in that the energy collecting device is integrated inside the carrying platform, and the wave energy is indirectly collected through the vibration energy generated by the wave action of the collecting platform. Since the second category of collecting devices is developed later, the existing categories are not many.
Obviously, the first. The two types of devices cannot collect wave energy efficiently, so that the two types of devices cannot collect the wave energy efficiently. In order to make up for the defects, the invention provides a device capable of fully utilizing and collecting waves, so that the device has practical value.

The filter screen 2-4 is arranged at a certain distance from the bottom of the hydraulic collecting cylinder, so that liquid can flow in the hydraulic collecting cylinders, and the rigid piston 1 is pushed to move upwards. The upper surface of the rigid piston 1 is directly contacted with seawater, when the wind is calm and calm, the pressure generated by the gravity and the liquid level difference of the rigid piston 1 is balanced with the elastic force of the spring, when the seawater moves, the wave causes a larger pressure difference between the sea surface and the seabed, the hydrodynamic pressure generated by the pressure difference directly acts on the upper surface of the rigid piston 1, the rigid piston 1 moves downwards, and the periphery of the rigid piston 1 is contacted with the hydraulic collecting cylinder 2.

Detailed Description
The following detailed description of the invention refers to the accompanying drawings.
A device for collecting wave energy by utilizing wave water pressure comprises a rigid piston 1, a hydraulic collecting cylinder 2, a one-way valve 3, a loop pipeline 5, a turbine generator, a spray pipe 8 and an energy storage device 9, wherein the turbine generator comprises a turbine 7 and a generator 6. The whole device is connected as follows: the integral device is arranged between a wave 4 and a wave crest, the integral device is arranged on the seabed, six hydraulic collecting cylinders 2 are connected in series, a rigid piston 1 is connected in a sealing mode in a hydraulic cylinder box body 2-2, a one-way valve 3 is arranged between the hydraulic collecting cylinders 2 and the hydraulic collecting cylinders, the left side of the hydraulic collecting cylinders 2 is connected with one end of a loop pipeline 5, and an energy accumulator 9, a spray pipe 8, a turbine 7 and a generator 6 are arranged on the loop pipeline 5. The other end of the loop pipeline 5 is connected with the right side of the hydraulic collecting cylinder 2. The whole device is arranged along the wave propelling direction, when the sea surface is calm, the elasticity borne by the spring 2-3 in the hydraulic collecting cylinder 2 is equal to the sum of the tiny dynamic water pressure generated by the rigid piston 1 and the liquid level difference. When the seawater flows, waves are generated, the hydrodynamic pressure generated by the waves is increased, so that the rigid piston 1 moves downwards, the hydrodynamic pressure applied to the hydraulic collecting cylinder corresponding to the wave crest is the largest between the wave crest 4 and the wave trough, the hydrodynamic pressure applied to the hydraulic collecting cylinder corresponding to the wave trough is the smallest, and the working liquid can only flow from a place with large pressure to a place with small pressure due to the one-way valve 3. Circulation is achieved through the loop conduit 5. The hydraulic collecting cylinder 2 is connected with the rigid piston 1 through a sealing ring, so that seawater is prevented from entering the internal hydraulic cylinder body to cause corrosion. The energy storage 9, the turbine 7, the generator 6, the spray pipe 8 and the like can be installed on land or under the sea according to specific application sites, so that the corrosion and the scouring of seawater can be reduced during the on-land installation, the service lives of the energy storage and the turbine generator can be ensured to the maximum extent, and meanwhile, a loop pipeline can be increased, so that the power generation efficiency is slightly reduced; when the device is installed on the seabed, the power generation efficiency can be guaranteed to the maximum extent, but the device also needs to be protected, a protective shell is added, and corrosion and scouring of seawater to the device are reduced.
When the wave 4 advances forwards, the corresponding pressure on the seabed changes along with the change of the wave height, so that the pressure on each horizontal position of the seabed is different, pressure difference is generated, and the pressure acts on the rigid piston 1 to promote the up-and-down reciprocating motion of the rigid piston. In the hydraulic collecting cylinder 2, when the rigid piston 1 moves downwards, the working fluid in the hydraulic collecting cylinder 2 is pressurized, when the pressure reaches the set pressure of the check valve 3 on the left side of the hydraulic collecting cylinder, the check valve 3 on the left side is opened, the fluid cannot flow rightwards due to the existence of the check valve 3 on the right side, and the working fluid can only flow leftwards in a one-way mode, meanwhile, because the waves are continuous, the hydraulic collecting cylinder 2 on the stage can receive the high-pressure collected fluid from the right side at the same time, the set pressure of the check valves 3 on each stage except the check valve at the inlet of the check valve on the rightmost side is gradually reduced from right to left, so that the working fluid can smoothly enter the hydraulic collecting cylinder 2 on the next stage, the hydraulic collecting cylinder on the leftmost side is connected with a loop pipeline, and finally the high-pressure collected fluid is collected in the loop pipeline, so that the working.
Working liquid in the hydraulic collecting cylinder 2 flows out from the left side, hydraulic energy is collected after the working liquid passes through the energy storage device 9, the working liquid flowing out of the energy storage device 9 is subjected to pressure reduction and speed increase along the loop pipeline 5 through the spray pipe 8 and then reaches the turbine 7 and the generator 6, the turbine 7 converts the hydraulic energy of the working liquid into mechanical energy which can be directly converted by the motor 6, further, the motor 6 converts the mechanical energy into electric energy which can be commonly used, and finally, the working liquid flows back to the hydraulic collecting cylinder 2 on the right side of the system through the loop pipeline 5 after passing through the turbine generator to complete circulation, so that wave energy is converted into electric energy which can be directly used, and the electric energy can be collected through the collecting device. The system can work continuously and stably by repeating the steps, and the purposes of wave energy collection and final power generation are achieved.
