[0032] As Figure 1 , Figure 2As shown, in this embodiment, an automatic seawater desalination device based on wave energy is provided, which specifically comprises: a mounting base 4 arranged on a floating body, one side of the mounting base 4 is connected to one end of an elastic member 5, the other end of the elastic member 5 is connected to one end of a traction member 1, the other end of the traction member 1 is connected to a seabed anchor after passing through a driving wheel 10; the driving wheel 10 is drivingly connected with a driven wheel 11, the driven wheel 11 is connected with a water pump 15; the water inlet end of the water pump 15 is connected with a water inlet pipe 14, the water outlet end of the water pump 15 is communicated with a membrane shell 17; the membrane shell 17 is communicated with a water storage tank through a water outlet pipe 18.

[0033] Specifically, in a specific embodiment, a guide wheel 2 is rotatably arranged on the mounting base 4, and the other end of the traction member 1 is connected to the seabed anchor after passing through the driving wheel 10 and being guided through the guide wheel 2. Specifically, a first guide shaft 3 is rotatably arranged on the mounting base 4, and the guide wheel 2 is arranged on the first guide shaft 3.

[0034] Specifically, in a specific embodiment, a driving wheel support 7 is arranged on the floating body, and the driving wheel 10 is rotatably arranged on the driving wheel support 7. Specifically, a second guide shaft 9 is rotatably arranged on the driving wheel support 7, a one-way bearing 8 is arranged on the second guide shaft 9, and the driving wheel 10 is connected to the end of the second guide shaft 9.

[0035] In a specific embodiment, a driven wheel support 13 is arranged on the floating body, and the driven wheel 11 is rotatably arranged on the driven wheel support 13. Specifically, a third guide shaft 12 is rotatably arranged on the driven wheel support 13, the driven wheel 11 is arranged on the third guide shaft 12, and one end of the third guide shaft 12 is connected to the rotating shaft of the water pump 15.

[0036] In a specific embodiment, a limiting member 6 is arranged on the floating body, and the elastic member 5 is movably arranged through the limiting member 6. In this embodiment, the elastic member is a spring. The limiting member 6 is a frame arranged on the driving wheel support 7. In other embodiments, the limiting member 6 can also be a hollow pipe fixedly connected at one end to the mounting base 4, and the elastic member 5 is arranged in the hollow pipe.

[0037] In a specific embodiment, a pressure detector 19 is arranged on the water outlet pipe 18.

[0038] In a specific embodiment, a power module is further arranged on the floating body, which is used to supply power to the pressure detector 19 or other components requiring power. The power module can include a storage battery, a solar photovoltaic panel, or a water turbine generator arranged on the water outlet pipe 18.

[0039] In this embodiment, the spring deforms or recovers when the wave causes the floating body to float up and down. The system is configured with a limiting member 6 for limiting the deformation of the spring when the sea wave is too high to prevent the device from being damaged. Specifically, when the sea wave pushes the floating body to float up, the spring deforms, stores elastic potential energy, and the ship anchor cable drives the guide wheel 2, the first guide shaft 3 and the second guide shaft 9 to rotate counterclockwise, the one-way bearing 8 prevents any counterclockwise rotation to save energy, causing the driving wheel 10 to be in a static state, and in turn not driving the water pump 15 to work. With the sea wave pushing the floating body to sink, the spring recovers, releasing the stored elastic potential energy, and the ship anchor cable drives the guide wheel 2, the first guide shaft 3 and the second guide shaft 9 to rotate clockwise, and in turn the one-way bearing 8 rotates clockwise, the one-way bearing 8 drives the driving wheel 10 to rotate clockwise, and the driving wheel 10 drives the driven wheel 11 to rotate, and the driven wheel 11 drives the water pump 15 to pump water.

[0040] As shown in Figure 1 In this embodiment, the floating body can be a ship body, and the traction member 1 can be a ship anchor cable. The combination of the ship anchor cable and the guide wheel 2 can reduce friction and reduce energy loss. Figure 2 As shown in The one-way bearing 8 ensures that when the floating body floats up and the ship anchor cable drives the guide wheel 2 to rotate counterclockwise, the second guide shaft 9 will not drive the driving wheel 10 to rotate counterclockwise, and in turn the driven wheel 11 will not generate a force to drive the outer shaft of the water pump 15 to rotate clockwise, achieving the effect of not changing the outer shaft of the water pump 15 from clockwise rotation to counterclockwise rotation when the spring recovers from deformation after the ship anchor cable tension disappears, avoiding additional work, saving energy, and prolonging the service life of the equipment and improving the efficiency of the system. The gear system includes a driving wheel 10 with low speed and large torque and a driven wheel 11 with high speed and small torque. The speed deficiency of the driving wheel 10 is compensated by acceleration, and the driven wheel 11 drives the second guide shaft 9, thereby effectively driving the water pump 15 to work. The driving wheel 10 drives the driven wheel 11, such as a belt pulley, which is connected and driven by a transmission belt, or the driving wheel 10 and the driven wheel 11 are two gears that mesh with each other and are driven by gear meshing.

[0041] The driven wheel 11 transmits mechanical energy to the water pump 15 through its rotation. The outer shaft of the water pump is connected with the gear system, and sea water is introduced into the water pump inlet through the rotation of the sea water inlet pipe 14. After being pressurized by the water pump 15, the sea water enters the sea water conveying pipe 16 through the water pump outlet and is sent into the membrane shell 17 under high pressure. The membrane shell 17 uses reverse osmosis technology to generate pure fresh water, which flows out through the fresh water outlet pipe 18 and enters the water storage system.

[0042] The purified fresh water after the reverse osmosis desalination treatment is discharged through the fresh water outlet pipe 18, and drives the water turbine 20 to rotate. The water turbine 20 converts the water flow energy into electric energy through rotation, and stores the electric energy for use by other parts of the device. In order to realize intelligent monitoring of the water level, a pressure detector 19 is arranged at the water outlet. The pressure detector 19 is used to monitor the pressure change in the water storage cylinder in real time, thereby indirectly measuring the water level in the water storage cylinder. According to the change of the water level, the pressure detector 19 can trigger an alarm system, and when the water level in the water storage cylinder reaches the preset maximum value, an alarm is issued to prompt the operator to take out fresh water in time, so as to ensure that the water storage cylinder will not be damaged due to overfilling.

[0043] In summary, the working principle of the automatic seawater desalination device based on wave energy is as follows: when the sea wave pushes the floating body to float upwards, the ship anchor cable drives the guide wheel 2, the first guide shaft 3 and the second guide shaft 9 to rotate counterclockwise, the spring deforms, stores elastic potential energy, the limiting piece 6 limits the maximum deformation of the spring to prevent damage to the device, the one-way bearing 8 prevents any counterclockwise rotation to save energy, causing the driving wheel 10 to be in a stationary state, thereby not driving the water pump 15 to work. As the sea wave pushes the floating body to sink, the tension of the ship anchor cable disappears, the spring restores the deformation, releases the stored elastic potential energy, the ship anchor cable drives the one-way bearing 8 and the second guide shaft 9 to rotate clockwise, thereby driving the driving wheel 10 to rotate clockwise. The driving wheel 10 with low speed and large torque drives the driven wheel 11 with high speed and small torque to rotate counterclockwise to achieve acceleration effect, and the driven wheel 11 in turn drives the second guide shaft 9, thereby effectively driving the water pump 15 to work. The water pump 15 introduces seawater from the seawater inlet pipe 14 into the water pump inlet. After being pressurized by the water pump, the seawater enters the seawater conveying pipe 16 through the water pump outlet and is sent into the membrane shell 17 under high pressure, and the generated fresh water flows out through the fresh water outlet pipe 18. The fresh water drives the water turbine 20 to rotate. The water turbine 20 converts the water flow energy into electric energy through rotation, and stores the electric energy for use by other parts of the device. The pressure detector 19 is used to monitor the pressure change in the water storage cylinder in real time, and when the water level in the water storage cylinder reaches the preset maximum value, an alarm is issued to prompt the operator to take out fresh water in time.
