Description

Technical Field

[0001] The present invention relates to the field of water treatment technology, and in particular to a seawater desalination device based on wave energy power generation. Background Art

[0002] Common desalination technologies, such as distillation and reverse osmosis, consume large amounts of electricity or heat. Wave power generation harnesses the energy of ocean waves and converts it into electricity. Previous desalination systems that integrated wave power generation typically employed separate wave power generation systems and desalination units, each designed and arranged separately. The wave power generation system then collected electricity to power the desalination unit. While this approach is suitable for large-scale applications, miniaturization for portable deployment is difficult. Summary of the Invention

[0015] The present invention securely mounts the distillation component of the seawater desalination module to a bracket within a wave-powered power generation module. The seawater in the distillation component moves with the external wave energy, offsetting the instantaneous acceleration of wave impact through inertia, reducing the overall oscillation amplitude of the device and creating a buffering effect. This, in turn, does not alter the periodicity of the bracket's swing, thus ensuring wave power generation efficiency. Furthermore, the freshwater storage chamber balances the center of gravity of the overall structure, ensuring excellent stability under wave impact. The integration of the distillation component and bracket makes the wave-powered seawater desalination device more compact and easier to deploy. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described below with reference to the following examples. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading this description, various equivalent modifications to this description by those skilled in the art fall within the scope defined by the claims appended to this application.

[0026] Please combine Figure 1 and Figure 2 As shown, the seawater desalination device based on wave energy power generation in this embodiment includes a shell 1, a power generation module and a seawater desalination module.

[0027] The housing 1 is equipped with a forward cabin 101 and a transom 102. The forward cabin 101 houses the power generation and desalination modules, while the transom 102 is vertically fixed to the rear end of the forward cabin 101. The entire housing 1 is shaped like a fish, with the front of the forward cabin 101 and the transom 102 serving as hollow floating structures. When waves approach from the side of the device, the device can automatically orient itself in the direction of the waves, effectively utilizing wave energy.

[0028] Please combine Figure 3 、 Figure 4 As shown, the power generation module includes a swingable bracket 2, a linear reciprocating mechanism, a runner 3, a generator 4, a rectifier 5, and a battery 6. A fresh water storage chamber 8 is fixed to the bottom of the front cabin 101 via a fixed connector 7. Fresh water storage chamber 8 is part of the seawater desalination module and is secured to a base 9.

[0029] The bracket 2 includes a rectangular top frame 201, which is hinged to two connecting rods 202 on both sides of the rectangular top frame 201. The bottom ends of the connecting rods 202 are hinged to the base 9, so that the rectangular top frame 201 can swing in the front and rear directions of the front cabin 101.

[0030] The linear reciprocating mechanism includes a piston cylinder 10 and a piston 11. The piston cylinder 10 is fixedly mounted on the base 9. The piston 11 is disposed within the piston cylinder 10 and can move back and forth. Springs are provided at both ends of the inner cavity of the piston cylinder 10 to cushion the reciprocating movement of the piston 11. The piston 11 is connected to the rectangular top frame 201 via a first connecting rod 12. Specifically, the top end of the first connecting rod 12 is hinged to the rear beam 201a of the rectangular top frame 201, and the bottom end of the first connecting rod 12 is hinged to the piston 11. When the rectangular top frame 201 swings back and forth due to the influence of waves, the first connecting rod 12 causes the piston 11 to move back and forth within the piston cylinder 10.

[0031] Triangular supports 14 are located on either side of the base 9. These supports support a rotating shaft through bearings, to which the runner 3 is fixed. A second connecting rod 13 connects the piston 11 and the runner 3. The head end of the second connecting rod 13 is hinged to the piston 11, and the tail end of the second connecting rod 13 is eccentrically connected to the runner 3. As the piston 11 moves back and forth within the piston cylinder 10, the second connecting rod 13 drives the runner 3, thereby rotating the rotating shaft. The arrangement of the triangular supports 14 provides stable support for the rotating shaft of the runner 3. A generator 4, a rectifier 5, a battery 6, and a control module 15 are fixed to the base 9. A sprocket drive mechanism 16 is connected between the input shaft of the generator 4 and the rotating shaft. Rotation of the rotating shaft drives the generator 4, thereby converting wave energy into electrical energy. The electrical energy output by the generator 4 is stored in the battery 6 via the rectifier 5.

[0032] Please combine Figures 5 to 9 As shown, the seawater desalination module includes, in addition to the aforementioned fresh water storage chamber 8 , a water pump 17 , a distillation component 18 , a pressurizer 19 , a reverse osmosis membrane component 20 and a drainage pump 21 .

[0033] The distillation component 18 is an openable closed cavity, including an evaporation tank 1801 and a preliminary desalination water reservoir 1802. The distillation component 18 is fixedly mounted on the rectangular top frame 201, and is connected to the side beams 201b of the rectangular top frame 201 on both sides, and swings with the swing of the bracket 2. Inside the distillation component 18, above the evaporation tank 1801 is an inclined condensation top plate 1803, which also extends above the preliminary desalination water reservoir 1802. A heater 1804 is provided in the evaporation tank 1801, and the evaporation tank 1801 is provided with a water inlet 1801a connected to the outlet of the water pump 17. The inlet of the water pump 17 is connected to the water pump pipe 22, and a filter is provided on the water pump pipe 22. The inlet of the water pump 17 is provided outside the outer shell 1. The pump 17 and heater are powered by the battery 6 and controlled by the control module 15. When the pump 17 is operating, it supplies seawater to the evaporation pool 1801. The heater 1804 heats and evaporates the seawater. The water vapor condenses on the condensation top plate 1803 and flows into the primary desalination reservoir 1802, where the seawater is initially purified. A level gauge 1805 can be installed in the evaporation pool 1802 to monitor water level changes. When evaporation reaches a certain level, the control module 15 reverses the pump 17 to drain the wastewater from the evaporation pool 1801 and then re-pump seawater for evaporation.

[0034] The primary desalination water reservoir 1802 is connected to the pressurizer 19 via an outlet pipe 23. The outlet of the pressurizer 19 is then connected to the reverse osmosis membrane unit 20 via a pipe 24. The reverse osmosis membrane unit 20 is fixed to the side of the base 9 near the tail plate 102. The reverse osmosis membrane unit 20 is provided with a water inlet 2001, a water outlet 2002, and a wastewater discharge port 2003. The pipe 24 connected to the outlet of the pressurizer 19 is connected to the water inlet 2001. The reverse osmosis membrane 2004 is fixed in the housing of the reverse osmosis membrane unit 20 and arranged in a zigzag pattern. After the water in the primary desalination water reservoir 1802 is pressurized and enters the reverse osmosis membrane unit 20, it is further purified by the reverse osmosis membrane 204. The final purified water is discharged through the outlet 2002. The outlet 2002 is connected to the fresh water storage chamber 8 via a pipe 25, where the purified water is stored. The wastewater outlet 2003 is connected to the drainage pump 21, which pumps out the wastewater generated by the reverse osmosis filtration and discharges it into the ocean through the wastewater pipeline 26. The pressurizer 19 and the drainage pump 21 are both powered by the battery 6 and controlled by the control module 15.

[0035] In this embodiment, the power generation module and the seawater desalination module are compactly arranged in the front cabin 101 so that the center of gravity of the device is located in the front cabin 101. The hollow floating structure of the front end of the front cabin 101 and the tail plate 102 is used to adjust the posture by itself. The distillation component 18 of the seawater desalination module produces a buffering effect in the waves, so that the center of gravity of the entire structure remains balanced and maintains good stability under wave impact, thereby improving the efficiency of wave power generation.
