[0052] See also Figure 1 A binary gas storage type ocean wave energy utilization device provided in an embodiment of the present application includes: a device body 10, a piston 20 and a floating body 30.

[0053] The device body 10 is provided with a piston chamber 11 , a low-pressure air inlet 12 , a low-pressure air outlet 13 , a high-pressure air inlet 14 , a high-pressure air outlet 15 and a first air storage chamber 16 .

[0054] The piston 20 is slidably disposed in the piston cavity 11, and the piston cavity 11 is divided into a first cavity 111 and a second cavity 112. In this embodiment, the second cavity 112 is located above the first cavity 111. The float 30 is floated on the sea surface and is fixedly connected to the piston 20. The float 30 will follow the ups and downs of the waves and drive the piston 20 to move up and down in the piston cavity 11, so that the first cavity 111 and the second cavity 112 expand and contract asynchronously.

[0055] The low-pressure air inlet 12 is connected to the outside of the device body 10 and the first cavity 111; the low-pressure air outlet 13 is connected to the first cavity 111 and the first air storage chamber 16; the high-pressure air inlet 14 is connected to the first air storage chamber 16 and the second cavity 112; the high-pressure air outlet 15 is connected to the second cavity 112; the low-pressure air inlet 12, the low-pressure air outlet 13 and the high-pressure air inlet 14 are all provided with a one-way valve 41. The high-pressure air outlet 15 is provided with a pressure valve 42.

[0056] As the waves move toward the trough, the float 30 descends due to gravity and drives the piston 20 downward, causing the piston 20 to compress the gas in the first cavity 111 and press the gas into the first air storage chamber 16. At this time, the gas is compressed for the first time in the first cavity 111, and in this process, the volume of the second cavity 112 increases to draw the gas in the first air storage chamber 16 into the second cavity 112.

[0057] As the waves move toward the crest, the volume of the first cavity 111 increases, causing the gas outside the device body 10 to be drawn into the first cavity 111 through the low-pressure air inlet 12. At the same time, the volume of the second cavity 112 decreases, compressing the gas in the second cavity 112. At this time, the gas is compressed for the second time in the second cavity 112; the gas after the second compression is discharged through the high-pressure air outlet 15.

[0058] That is, in the device provided in the present solution, the external gas can be sucked into the piston chamber 11 through the ups and downs of the waves, and the gas can be compressed in the first cavity 111 and the second cavity 112 respectively; the compression effect and compression efficiency can be effectively improved by using the multi-stage compression method of the gas. At the same time, the multi-stage compression process of the gas occurs in the piston chamber without the need for other external compression structures, which can effectively simplify the structure of the device and help to make the device structure more compact.

[0059] It should be noted that the high-pressure gas outlet 15 can be connected to an external gas storage tank to store the compressed gas.

[0060] Furthermore, in this embodiment, the gas backflow can be effectively prevented by multiple one-way valves 41. Specifically, the one-way valve 41 located on the low-pressure air inlet 12 can prevent the gas from flowing out of the first cavity 111 to the outside of the device body 10; the one-way valve 41 located on the low-pressure air outlet 13 can prevent the gas from flowing from the first gas storage chamber 16 to the first cavity 111; the one-way valve 41 located on the high-pressure air inlet 14 can prevent the gas from flowing from the second cavity 112 to the first gas storage chamber 16.

[0061] The pressure valve 42 located on the high-pressure gas outlet 15 can also prevent the gas outside the high-pressure gas outlet 15 from flowing into the second cavity 112. In addition, the pressure valve 42 on the high-pressure gas outlet 15 can be opened after the gas pressure in the second cavity 112 reaches a preset pressure value; specifically, a pressure opening and closing port can be provided on the pressure valve 42; when the gas pressure in the second cavity 112 reaches a preset pressure value, the pressure opening and closing port opens, so that the gas can be discharged from the high-pressure gas outlet 15. In application, the pressure opening and closing port can be a deformable valve sheet or the like.

[0062] In one embodiment, a compression chamber 50 is formed between the float 30 and the device body 10. Since the compression chamber 50 is formed by the float 30 and the device body 10, the compression chamber 50 can change in volume as the float 30 rises and falls with the waves.

[0063] The device body 10 is provided with a second air inlet 17 and a second air outlet 18; the second air inlet 17 connects the outside of the device body 10 with the compression chamber 50; the second air outlet 18 connects the compression chamber 50 with the first air storage chamber 16; and a one-way valve 41 is provided on each of the second air inlet 17 and the second air outlet 18. When the floating body 30 sinks to enlarge the compression chamber 50, gas is drawn into the compression chamber 50 from the second air inlet 17; when the floating body 30 rises to shrink the compression chamber 50, gas is compressed for the first time in the compression chamber 50 and is pressed into the first air storage chamber 16.

[0064] It should be noted that the one-way valve 41 on the second air inlet 17 is used to prevent gas from flowing from the compression chamber 50 to the outside of the device body 10; the one-way valve 41 on the second air outlet 18 is used to prevent gas from flowing from the first air storage chamber 16 into the compression chamber 50.

[0065] In this embodiment, the float 30 is arranged outside the device body 10; by arranging the float 30 and the device body 10 to enclose the compression chamber 50, the process of the float 30 rising and falling relative to the device body 10 can be used synchronously with the reciprocating motion of the piston 20. Among them, since the float 30 is an original component of the device, the device can still realize the multi-region synchronous compression of the gas without setting up a separate compression structure, thereby improving the compression efficiency.

[0066] In another embodiment, a compression chamber 50 is enclosed between the float 30 and the device body 10. In the process of the float 30 following the ups and downs of the waves, the compression chamber 50 can produce a volume change following the ups and downs of the float 30. The compression chamber 50 is connected to the outside through the air inlet and is connected to the first chamber 111 through the air outlet; that is, in this embodiment, as the float 30 rises and falls, the gas is compressed for the first time in the compression chamber 50 and then pressed into the first chamber 111, so that the gas is compressed twice in the first chamber 111, and then enters the second chamber 112 and is compressed three times, so as to further compress the gas and enhance the compression effect. Correspondingly, a one-way valve 41 can be provided on the air inlet and the air outlet of the compression chamber 50.

[0067] In one embodiment, an air inlet passage 19 is disposed on the device body 10 ; the air inlet passage 19 is connected to the low-pressure air inlet 12 and the second air inlet 17 .

[0068] That is, in this embodiment, the low-pressure air inlet 12 and the second air inlet 17 share the same air inlet passage 19 .

[0069] As a further improvement, the device further comprises: a wind turbine 60; the wind turbine 60 is arranged on the air inlet passage 19. The wind turbine 60 may be connected to a battery, and after rotating to do work, the mechanical energy is converted into electrical energy and stored in the battery.

[0070] During the process of air intake into the first cavity 111 and the compression cavity 50 , gas flow is generated in the air intake passage 19 to drive the wind turbine 60 to rotate and do work, thereby generating electricity through the rotation of the wind turbine 60 .

[0071] Moreover, in this embodiment, the low-pressure air inlet 12 and the second air inlet 17 share the same air inlet channel 19, which can increase the airflow in the air inlet channel 19 and improve the work effect of the wind turbine 60, thereby increasing the power generation rate. It should be noted that the first cavity 111 and the compression cavity 50 are asynchronously expanded and contracted, that is, in the process of the volume of the first cavity 111 increasing, the volume of the compression cavity 50 gradually decreases, and in the process of the volume of the first cavity 111 decreasing, the volume of the compression cavity 50 gradually increases, so that the first cavity 111 and the compression cavity 50 can alternately drive the air inlet channel 19 to allow the wind turbine 60 to continuously rotate and generate electricity.

[0072] Optionally, a filter screen 61 is provided at the outer end of the air intake passage 19 to filter objects entering the air intake passage 19 and avoid clogging of the air intake passage 19 .

[0073] In one embodiment, a second air storage chamber 70 is further included; the second air storage chamber 70 is disposed on the device body 10 and is connected to the high-pressure air outlet 15 .

[0074] The second gas storage chamber 70 is used to store gas that has been compressed multiple times.

[0075] Optionally, a third air storage chamber 80 is further included; the third air storage chamber 80 is disposed on the device body 10 and is connected to the second air storage chamber 70 .

[0076] Correspondingly, in addition to the third air storage chamber 80, a fourth air storage chamber, a fifth air storage chamber, etc. may also be provided, and the number of air storage chambers is not limited. A pressure valve 42 is provided between the third air storage chamber 80 and the second air storage chamber 70. When the gas in the second air storage chamber 70 reaches a certain pressure, it can be discharged into the third air storage chamber 80 through the pressure valve 42 until the third air storage chamber 80 and the second air storage chamber 70 are equal in pressure.

[0077] Optionally, an elastic member 90 is also included; Figure 1 As shown, the elastic member 90 can be provided at both ends to connect the device body 10 and the floating body 30. In application, the elastic member 90 can also be provided at both ends to connect the device body 10 and the piston 20. Specifically, during the reciprocating motion of the floating body 30 and the piston 20 relative to the device body 10, the elastic member 90 can convert mechanical energy into elastic potential energy for storage, and when released, it can play the effect of pushing the piston 20 and the floating body 30 to move.

[0078] It should be noted that the piston 20 may be connected to the float 30 via a connecting rod 21 ; and the elastic member 90 may be a spring and sleeved on the connecting rod 21 .

[0079] The above are only preferred embodiments of the present application and are not intended to limit the present invention. Although the present application has been described in detail with reference to the examples, those skilled in the art can still modify the technical solutions described in the aforementioned examples or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made should be included in the protection scope of the present application.
