Description

Wave energy pressure amplification device and marine ranch feeding system and method Technical Field

[0001] The present invention relates to the field of marine ranch equipment, and in particular to a wave energy pressure amplification device and a marine ranch feeding system. Background Art

[0002] Wave energy generation is a green and environmentally friendly way of generating electricity. It is a technology that converts wave energy into electrical energy. It mainly uses wave energy to compress air to drive generators to generate electricity. Compressed air technology mainly increases the potential energy of air through the ups and downs of waves, thereby driving the operation of turbine generators.

[0003] For example, the Chinese invention patent with publication number CN114673623A discloses a wave energy storage and utilization device based on air compression, which can convert wave energy into air compression energy, store the heat generated during the air compression process, and combine the compression energy and heat to generate electricity, thereby realizing the storage and utilization of wave energy.

[0004] This method directly compresses air by exploiting the fluctuations of the sea surface. However, direct compression is limited by the fluctuations of the sea surface, making it difficult to compress the gas to a high pressure. Even if the air is compressed mechanically, the increased gas pressure increases the compression resistance, making further compression difficult. This limits the pressure of the outlet gas, making it difficult to use in applications requiring higher gas pressures. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention aims to provide a wave energy pressure amplification device to amplify the pressure at the outlet of the wave energy power generation device, thereby solving the problem of limited outlet pressure. The specific technical solution is as follows:

[0006] A first aspect of the present invention provides a wave energy pressure amplification device, characterized in that it comprises a transmission chamber, a compression chamber, an oil storage chamber and a buoy;

[0007] The transmission chamber is filled with hydraulic oil, and a first slider is provided on the hydraulic oil. The first slider is connected to a buoy floating on the sea surface, and the buoy is used to drive the first slider to move in the transmission chamber;

[0008] The transmission chamber is connected to the compression chamber via a first pipeline, a first one-way valve is provided in the first pipeline, and the first one-way valve is used to control the hydraulic oil in the transmission chamber to flow into the compression chamber and prevent backflow; the oil storage chamber is filled with hydraulic oil and connected to the transmission chamber via a second pipeline, a second one-way valve is provided in the second pipeline, and the second one-way valve is used to control the hydraulic oil in the oil storage chamber to flow into the transmission chamber and prevent backflow;

[0009] The upper portion of the compression chamber is connected to a gas pipeline for discharging the gas in the compression chamber. A gas outlet one-way valve is provided in the gas pipeline.

[0010] Preferably, a water tank is provided above the compression chamber, a first one-way water inlet valve is provided at the lower portion of the water tank, and a first one-way water outlet valve is provided at the upper portion of the water tank, and the first one-way water outlet valve is connected to the water outlet pipe;

[0011] A second slider is provided in the compression chamber, and a third slider is provided in the water tank. The second slider can drive the third slider to move up and down synchronously.

[0012] The second slider arranged in the compression chamber drives the third slider in the upper water tank to move up and down. The rise of the third slider increases the pressure in the upper part of the water tank and reduces the pressure in the lower part. The first one-way water inlet valve at the lower part takes in water, while the first one-way water outlet valve at the upper part discharges water. The seawater flows out from the outlet pipe for further use.

[0013] Preferably, the second slider and the third slider are fixedly connected via a connecting rod.

[0014] Fixing through a connecting rod is a relatively simple and low-cost design solution, but waterproof measures must be taken at the connection between the connecting rod and the water tank. The principle of like charges repel each other can also be used to set magnetic blocks on the second slider and the third slider so that the second slider drives the third slider to move up and down.

[0015] Preferably, the oil storage chamber is connected to the compression chamber via a third pipeline, and a third one-way valve is provided in the third pipeline, and the third one-way valve is used to control the hydraulic oil in the compression chamber to flow into the oil storage chamber and prevent backflow;

[0016] A self-holding electromagnetic induction switch is provided at the top and bottom of the compression chamber. An electromagnet for controlling the opening or closing of the third one-way valve is provided at the third one-way valve. The self-holding electromagnetic induction switch is electrically connected to the electromagnet to control the power on or off of the electromagnet.

[0017] Since an oil storage chamber is provided, the hydraulic oil can form a path circulation of oil storage chamber → transmission chamber → compression chamber → oil storage chamber, so that the second slider and the third slider can form a reciprocating motion, and the wave energy can be reused. At the same time, since self-holding electromagnetic induction switches are provided at the top and bottom of the compression chamber, when the second slider reaches the highest position, the self-holding electromagnetic induction switch detects an increase in magnetic flux, the switch closes, and the electromagnet is energized to open the third one-way valve, so that the hydraulic oil in the compression chamber flows into the oil storage chamber. After that, the second slider descends, and after descending to the lowest point, the self-holding electromagnetic induction switch is triggered, the switch is closed, the electromagnet is de-energized, and the third one-way valve is closed, and the cycle is repeated.

[0018] In some preferred embodiments, the compression chamber and the transmission chamber are both cylindrical, and the cross-sectional area of ​​the compression chamber is larger than the cross-sectional area of ​​the transmission chamber.

[0019] Both the transmission chamber and the compression chamber are designed as cylinders, allowing the first and second sliders to smoothly move up and down within their respective chambers and compress the hydraulic oil. Due to the larger cross-sectional area of ​​the compression chamber, a greater volume of gas can be stored within it, and a greater volume can be squeezed out of the exhaust check valve at one time, thereby improving the efficiency of wave energy compression of gas. Furthermore, according to Pascal's principle (pressure = pressure * area), the hydraulic pressure in the compression chamber and the transmission chamber is the same, but the compression chamber has a larger cross-sectional area, resulting in greater hydraulic pressure and external work, capable of compressing more gas and transporting more seawater. This can be applied to pipeline cleaning and meeting the needs of large-scale marine ranching.

[0020] Preferably, the oil storage chamber is arranged around the outside of the compression chamber.

[0021] Providing the oil storage chamber around the compression chamber can effectively utilize space and improve stability.

[0022] Preferably, a second one-way water inlet valve is further provided at the upper portion of the water tank, and a second one-way water outlet valve is further provided at the lower portion.

[0023] As the third slider in the water tank rises, the air pressure in the upper part of the water tank increases and the air pressure in the lower part decreases. The first one-way water outlet valve at the upper part opens under pressure, and the first one-way water inlet valve at the lower part opens, and seawater flows into the pipeline from the first one-way water outlet valve; the same applies when descending, the second one-way water outlet valve at the lower part opens, and the second one-way water inlet valve at the upper part opens, thereby converting wave energy into gravitational potential energy of water.

[0024] A second aspect of the present invention further provides a marine ranch feeding system, comprising the above-mentioned wave energy pressure amplification device, and further comprising: a turbine generator set, an air storage tank, a water reservoir, and a feeding pipeline, wherein the turbine generator set is provided with a first air port and a second air port, the first air port being connected to the outside air, and the air storage tank is provided with an air inlet and an air outlet;

[0025] The gas pipeline includes a first branch pipe and a second branch pipe, the first branch pipe is connected to the gas inlet of the gas storage tank, and a first one-way valve is provided between the first branch pipe and the second branch pipe; the second branch pipe is connected to the second gas port of the steam turbine generator set, and a second one-way valve is provided between the first branch pipe and the second branch pipe;

[0026] The water reservoir is provided with a water inlet and a water outlet, and the water inlet is connected to the water outlet pipe of the water tank;

[0027] The feeding pipe is connected to the feed outlet of the marine ranch feeding system. A spray ring is provided in the feeding pipe. Several high-pressure gas atomizing nozzles are provided on the ring body of the spray ring. The high-pressure gas atomizing nozzles are connected to the water outlet of the water reservoir and the gas outlet of the gas storage tank.

[0028] Preferably, the spray ring is arranged in the feeding pipe near the feed outlet.

[0029] Preferably, there are multiple spray rings, wherein the high-pressure gas atomizing nozzle in at least one spray ring is oriented parallel to the feeding pipe.

[0030] The third aspect of the present invention further provides a feeding method based on the above-mentioned marine ranch, comprising the following steps: S1: upon receiving a feeding instruction, opening a feeding outlet;

[0031] S2: Obtaining the pressure value in the gas tank and determining whether the pressure value in the gas tank is greater than a first threshold value. If so, opening the valves on the gas tank and the water reservoir so that the high-pressure gas-water mixture sprayed from the high-pressure atomizing nozzle impacts the feed in the feeding pipe and forms an air-water film on the wall of the feeding pipe; after the feeding outlet is closed, delaying a preset time, closing the valves on the gas tank and the water reservoir to end feeding;

[0032] S3: If not, intermittently open the valves on the air storage tank and the water storage tank while the feeding outlet is open, and execute S4;

[0033] S4: Continuously obtain the pressure value in the gas storage tank. When the pressure value in the gas storage tank reaches a first threshold, open the valves on the gas storage tank and the water reservoir at the same time, clean the pipeline after feeding, and end feeding.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] The first aspect of the present invention provides a wave energy pressure amplification device, which collects wave energy through a float and uses the ups and downs of the float to drive the movement of the first slider in the transmission chamber. When the first slider descends, the hydraulic oil in the transmission chamber is compressed, thereby opening the first one-way valve, and the hydraulic oil in the transmission chamber flows into the compression chamber, thereby increasing the pressure of the upper gas in the compression chamber; when the first slider rises, the second one-way valve opens, and the hydraulic oil in the oil storage chamber flows into the transmission chamber. When the float drives the first slider to descend again, the hydraulic oil in the transmission chamber flows into the compression chamber again, and the hydraulic oil in the compression chamber gradually increases. The pressure of the upper gas gradually increases. When it reaches the set value, the gas outlet one-way valve in the gas pipeline is opened. The present invention uses the compression chamber to store gas, and the internal gas is squeezed by the hydraulic oil to increase its pressure continuously. After reaching the set value, it is discharged from the gas outlet one-way valve, thereby achieving the purpose of amplifying the outlet pressure, which is conducive to better utilization and conversion of wave energy;

[0036] A second aspect of the present invention provides a marine ranch feeding system based on the above-mentioned wave energy pressure amplification device. The wave energy pressure amplification device is connected to an existing marine ranch feeding system, and a turbine generator set, an air storage tank, a water reservoir and a feeding pipeline are provided. By connecting the gas pipeline to the turbine generator set, the turbine generator set can be used to generate electricity when external air is inhaled. The air storage tank and the water reservoir are respectively connected to the gas pipeline and the water outlet pipeline of the wave energy pressure amplification device. When the wave energy pressure amplification device is working, high-pressure gas can be stored in the air storage tank and seawater can be stored in the water reservoir. Moreover, the air storage tank and the water reservoir are connected to the high-pressure gas atomizing nozzle on the spray ring in the feeding pipeline. During the feeding process of the marine ranch, on the one hand, the high-pressure gas atomizing nozzle can be used to form an air-water film on the inner wall of the pipeline to avoid residual feed on the pipeline wall and waste. On the other hand, the pipeline can be cleaned after the feeding is completed.

[0037] The third aspect of the present invention provides a feeding method based on the above-mentioned marine ranch feeding system. By controlling the high-pressure atomizing nozzle during the feeding process according to the pressure value of the high-pressure gas in the gas storage tank, the valve control can be adjusted in time when the marine ranch feeding system is affected by the environment and the gas storage is insufficient, thereby effectively cleaning the pipeline.

[0045] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0046] Embodiment 1, as shown in FIG. 1 to FIG. 3 , this embodiment provides a wave energy pressure amplification device, which mainly includes a water tank 1 , a compression device 5 and a transmission chamber 14 .

[0047] The compression device 5 includes a compression chamber 9 and an oil storage chamber 6 surrounding the compression chamber 9. A transmission chamber 14 is filled with hydraulic oil. The transmission chamber 14 is connected to the compression chamber 9 via a first pipeline. A first check valve 12 is provided in the first pipeline to control the flow of hydraulic oil from the transmission chamber 14 into the compression chamber 9 and prevent backflow. The compression chamber 9 is connected to the oil storage chamber 6 via a third pipeline. A third check valve 11 is provided in the third pipeline to control the flow of hydraulic oil from the compression chamber 9 into the oil storage chamber 6 and prevent backflow. The oil storage chamber 6 is connected to the transmission chamber 14 via a second pipeline. A second check valve 13 is provided in the second pipeline to control the flow of hydraulic oil from the oil storage chamber 6 into the transmission chamber 14 and prevent backflow. As a result, the hydraulic oil circulates within each chamber along the path from transmission chamber 14 to compression chamber 9 to oil storage chamber 6 and then to oil storage chamber 14, under the control of the check valves. The water tank 1 is located above the compression chamber 9. A first slider 15 is provided in the transmission chamber 14 , and the first slider 15 is connected to the buoy 20 via a connecting device.

[0048] In this embodiment, the first slider 15 is connected to the buoy 20 through a connecting device. The specific structure is: the connecting device includes a first connecting rod and a second connecting rod, and the second end of the first connecting rod is rotatably connected to the first end of the second connecting rod through a rotating pin 19; the first end of the first connecting rod is hinged to the main body of the amplification device, and the hinge position is higher than the transmission chamber 14; the first slider 15 is arranged between the first end and the second end of the first connecting rod; the second end of the second connecting rod is fixedly connected to the buoy 20.

[0049] In a more preferred embodiment, the second connecting rod is perpendicular to the buoy 20, and the buoy 20 floats on the sea surface and rises and falls with the waves. When the buoy 20 descends, the second end of the first connecting rod is driven downward by the second connecting rod. Since the first end of the first connecting rod is fixed to the device body, the first slider 15 can be driven to descend in the transmission chamber 14 by the first connecting rod, thereby compressing the hydraulic oil in the transmission chamber 14.

[0050] A second slider 8 is provided in the compression chamber 9, and a third slider 3 is provided in the water tank 1. The third slider 3 moves synchronously with the second slider 8. In this embodiment, a relatively simple rigid connecting rod 7 is used to connect the second slider 8 and the third slider 3, and a sealing structure is provided at the connection between the connecting rod 7 and the water tank 1. This ensures that the distance between the third slider 3 and the second slider 8 is always a certain value. After the hydraulic oil enters the compression chamber 9, the second slider 8 rises, thereby driving the third slider 3 in the water tank 1 to rise. A gas pipeline 22 is also provided on the upper part of the compression chamber 9, and an outlet one-way valve 23 is provided in the gas pipeline 22. When the gas compressed by the second slider 8 reaches the set pressure, the outlet one-way valve 23 opens and flows out from the gas pipeline 22.

[0051] In some other embodiments, the principle of like charges repel each other may be adopted, and magnets may be provided at the top of the second slider 8 and the bottom of the third slider 3 to replace the connecting rod 7, thereby reducing the cost of structural design.

[0052] The upper part of the water tank 1 is provided with a first one-way water outlet valve 18 and a second one-way water inlet valve 2, and the lower part of the water tank 1 is provided with a first one-way water inlet valve 4 and a second one-way water outlet valve 16. The first one-way water outlet valve 18 and the second one-way water outlet valve 16 are respectively connected to the outlet pipe 17. When the third slider 3 rises, the pressure in the lower part of the water tank 1 decreases and the pressure in the upper part increases, so that the first one-way water inlet valve 4 at the lower part of the water tank 1 opens and the second one-way water outlet valve 16 is closed, and seawater enters the lower part of the water tank from the first one-way water inlet valve 4; the second one-way water inlet valve 2 at the upper part of the water tank 1 is closed, and the first one-way water outlet valve 18 is opened, and the seawater in the water tank 1 is discharged from the outlet pipe 17 via the first one-way water outlet valve 18.

[0053] Self-holding electromagnetic induction switches 21 are provided at the top and bottom of the compression chamber 9. The self-holding electromagnetic induction switch 21 is a prior art, that is, when it senses an increase in magnetic flux, the switch position changes, and when the magnetic flux weakens, the switch position remains. Only when the magnetic flux increases again will the switch position change again.

[0054] As shown in Figure 3 , an electromagnet 10 is installed at the third one-way valve 11 in the third pipeline. The valve disc of third one-way valve 11 is equipped with a metal component and connected to a spring 39. The other end of spring 39 is fixed to electromagnet 10. When electromagnet 10 is energized, it attracts the metal component of third one-way valve 11, causing the valve disc to open and compressing spring 39. When the power is removed, spring 39 rebounds, causing the valve disc to return to its original position and closing third one-way valve 11.

[0055] The electromagnet 10 is electrically connected to two self-holding electromagnetic induction switches 21. When the second slider 8 rises to the highest position, the self-holding electromagnetic induction switch 21 on the top of the compression chamber 9 senses the increase in magnetic flux and connects the electromagnet 10. The electromagnet 10 controls the third one-way valve 11 to open. The third one-way valve 11 is located in the third passage connecting the compression chamber 9 and the oil storage chamber 6, so that the hydraulic oil in the compression chamber 9 can flow back to the oil storage chamber 6, completing the flow cycle of the hydraulic oil. The above process is then repeated. The wave energy pressure amplification device can continuously convert wave energy into the pressure potential energy of gas for storage or direct use.

[0056] At this time, the oil pressure on the second slider 8 decreases, and it gradually descends under the action of gravity, driving the third slider 3 in the water tank 1 to descend. The pressure in the upper part of the water tank 1 decreases, while the pressure in the lower part increases, so that the second one-way water inlet valve 2 in the upper part of the water tank 1 opens, the first one-way water outlet valve 18 closes, the first one-way water inlet valve 4 in the lower part closes, the second one-way water outlet valve 16 opens, and seawater flows out from the outlet pipe 17.

[0057] When the second slider 18 moves to the bottom of the compression chamber 9, the self-holding electromagnetic induction switch 21 at the bottom of the compression chamber 9 senses the increase in magnetic flux, controls the electromagnet 10 to cut off power, and the spring 39 of the third one-way valve 11 resets to close the third one-way valve 11, and the compression chamber 9 and the oil storage chamber 6 are no longer connected.

[0058] Similarly, when the float 20 rises, the first slider 15 in the transmission chamber 14 rises, the second one-way valve 13 in the second passage opens and the first one-way valve 12 in the first passage closes, and the hydraulic oil in the oil storage chamber 6 flows into the transmission chamber 14. This flow of hydraulic oil does not involve the compression chamber 9, so the second slider 8 does not move.

[0059] Since the compression chamber 9 and the transmission chamber 14 are both cylindrical, the first slider 15 and the second slider 8 can be selected with a larger bottom area, so that they can move smoothly in their respective chambers, which is conducive to the squeezing of the hydraulic oil. The cross-sectional area of ​​the compression chamber 9 is larger than the cross-sectional area of ​​the transmission chamber 14. The two are equivalent to forming a communicating vessel. According to Pascal's principle: pressure = pressure * area, the pressure is constant. When the cross-sectional area increases, it is equivalent to amplifying the pressure. The hydraulic oil in the compression chamber 9 drives the second slider 8 to rise, and then compresses the gas in the upper part of the compression chamber 9. The cross-sectional area of ​​the compression chamber 9 is larger, and more gas can be stored therein, thereby improving the efficiency of compressing the gas. The gas pressure in the upper part of the compression chamber 9 gradually increases. When it reaches the set value, the gas outlet one-way valve 22 in the gas pipeline 22 opens, and the gas pressure flowing out of the gas pipeline 22 is amplified. It can be used for pipeline cleaning and to meet the needs of large-scale marine ranching. The gas flowing out of the gas pipeline 22 and the seawater flowing out of the water outlet pipeline 17 can also be stored, and the amplified pressure is converted into the gravitational potential energy of the water and the pressure potential energy of the gas.

[0060] Embodiment 2, as shown in FIG4 and FIG5 , based on embodiment 1, this embodiment further provides a marine ranch feeding system, including the wave energy pressure amplification device in embodiment 1.

[0061] In this embodiment, the wave energy pressure amplification device in the first embodiment is connected to the existing marine ranch feeding system to form the marine ranch feeding system in this embodiment;

[0062] Specifically, the marine ranch feeding system of this embodiment, based on the first embodiment and the existing marine ranch feeding system, further includes a turbine generator set 26, a gas storage tank 29, a water reservoir 35, and a feeding pipe 33, wherein the feeding pipe 33 is connected to the feed outlet of the existing marine ranch feeding system. The other parts of the marine ranch feeding system are common knowledge and will not be described in detail here.

[0063] The turbine generator set 26 is connected to a first air port 25 and a second air port, and the air storage tank 29 is provided with an air inlet and an air outlet;

[0064] The turbine generator set 26 and the gas storage tank 29 are both connected to the compression chamber 9 of the wave energy pressure amplification device through the gas pipeline 22 of the wave energy pressure amplification device. Specifically, the gas pipeline 22 includes a first branch pipe and a second branch pipe (see Figure 2). The first branch pipe is connected to the air inlet of the gas storage tank 29, and an air outlet check valve 23 is provided between the first branch pipe and the second branch pipe. The second branch pipe is connected to the second air port of the turbine generator set 26, and an air inlet check valve 24 is provided between the first branch pipe and the second branch pipe.

[0065] When the second slider 8 in the compression chamber 9 rises, the air pressure in the upper part of the compression chamber 9 increases, the outlet check valve 23 opens, and the inlet check valve 24 closes. The compressed gas in the upper part of the compression chamber 9 is discharged from the gas pipe 22 and flows into the gas storage tank 29 through the first branch pipe to be stored at a higher pressure.

[0066] When second slider 8 in compression chamber 9 descends, the air pressure above compression chamber 9 decreases. This opens inlet check valve 24 and closes outlet check valve 23. Air enters turbine generator set 26 through air inlet 25 and flows into compression chamber 9 via the second branch pipe, simultaneously driving turbine generator set 26. Turbine generator set 26 then uses the flowing air to rotate its blades and output electrical energy. This generated energy is stored in a battery and used to power both the device's electronically controlled switches and the rest of the ocean ranch platform's loads.

[0067] Furthermore, the air storage tank 29 is provided with a pressure gauge 30 and an air release valve 28. The pressure gauge 30 is electrically connected to the air release valve 28 and is used to feed back a pressure value signal to the feeding system, thereby controlling the air release valve 28 to release the air from the air storage tank 29 when the pressure in the air storage tank 29 exceeds a set value.

[0068] In a preferred embodiment, the air relief valve 28 is connected to the air inlet 25 through a pipeline. When the pressure in the air tank 29 exceeds a set value, the air relief valve 28 is controlled to delay the release of the air in the air tank 29. That is, when the pressure gauge 30 sends a signal to the system control end, the air is delayed so that the higher-pressure gas in the air relief valve 28 will rush into the air inlet 25, driving the turbine generator set 26 to do work. The setting of this part is set according to the gas storage capacity of the air tank 29 and the gas that can be compressed by the wave energy pressure amplification device within one feeding cycle of the feeding system. Those skilled in the art can make selective settings based on the above improvements in combination with their feeding system. The improvement of this part is also within the scope of the research results of the inventor of the present invention.

[0069] The water reservoir 35 is connected to the water outlet pipe 17 of the water tank 1. During the movement of the slider 3 in the water tank 1, seawater is injected into the water reservoir 35 through the water outlet pipe 17 of the water tank 1. A drain port 34 is also provided on the top of the water reservoir 35, and seawater can be discharged from the drain port 34 when it overflows.

[0070] A spray ring 32 is provided on the feeding pipe 33. Specifically, the spray ring 32 is fixed to the inner wall of the feeding pipe 33. The outer wall 36 of the spray ring 32 is in contact with the inner wall of the feeding pipe 33. The hollow portion of the spray ring 32 and the feeding pipe 33 together form a feed channel 38.

[0071] A plurality of high-pressure gas atomizing nozzles 37 are provided on the ring body of the spray ring 32 surrounding the feed channel 38. The air outlet of the gas storage tank 29 and the water outlet of the water reservoir 35 are connected to the high-pressure gas atomizing nozzles 37 on the spray ring 32 through pipes, wherein valves 31 are provided in the connected pipes.

[0072] Since the high-pressure gas atomizing nozzle 37 is connected to the gas storage tank 29 and the water reservoir 35 at the same time, when the two valves 31 are opened at the same time, the high-pressure gas in the gas storage tank and the seawater in the water reservoir enter the feeding pipe 33 together to form a high-pressure gas-water mixture.

[0073] In a more preferred embodiment, the marine ranch feeding system is further equipped with multiple sets of the wave energy pressure amplification devices, and the gas pipeline 22 of each wave energy pressure amplification device is connected to the gas storage tank 29, and the water outlet pipe 17 of each wave energy pressure amplification device is connected to the water reservoir 35. Therefore, when the working intensity of the feeding system is high or a large amount of feed is expected to be fed, the gas storage tank 29 and the water reservoir 35 can maintain a good working condition, avoiding the installation of additional pumping or pressurizing equipment.

[0074] Through the above structure, on the one hand, after the feed is fed into the feeding pipe 33, when the two valves 31 are opened at the same time, gas and seawater flow into the cleaning pipe 33 at the same time, forming a high-speed gas-liquid mixture under the gravity of the seawater and the pressure of the gas, thereby achieving high-pressure flushing of the feeding pipe 33;

[0075] On the other hand, when the two valves 31 are opened while feeding in the feeding pipe 33, when the high-pressure gas atomizing nozzle 37 in the spray ring 32 is directed parallel to the pipe or offset to the outer wall of the feeding pipe 33, an air-water film can be formed on the inner wall of the pipe, thereby avoiding direct contact between the feed and the pipe wall and reducing the residual feed on the pipe wall and causing waste;

[0076] Furthermore, by setting up multiple spray rings 32, and the directions of the high-pressure gas atomizing nozzles 37 in different spray rings 32 are different, different spray rings 32 can be controlled to open according to different needs. For example, in a specific solution, the direction of the high-pressure gas atomizing nozzle 37 in the spray ring 32 can be set. By pointing the direction of the high-pressure gas atomizing nozzle 37 toward the middle of the pipeline, the gas-liquid mixture impacts the feed, making the feed feeding more uniform and dispersed.

[0077] Based on the marine ranch feeding system in the above embodiment, the present invention further provides a marine ranch feeding control method, which specifically includes:

[0078] S1: When receiving the feeding command, open the feeding outlet;

[0079] S2: Obtaining the pressure value in the gas tank and determining whether the pressure value in the gas tank is greater than a first threshold value. If so, opening the valves on the gas tank and the water reservoir so that the high-pressure gas-water mixture sprayed from the high-pressure atomizing nozzle impacts the feed in the feeding pipe and forms an air-water film on the wall of the feeding pipe; and after the feeding outlet is closed, delaying a preset time, closing the valves on the gas tank and the water reservoir to end feeding;

[0080] Based on the above method, when the pressure value in the gas storage tank is high, during the feeding process, the high-pressure gas-water mixture is sprayed out. On the one hand, it impacts the feed, making the feeding more uniform and dispersed. On the other hand, it forms an air-water protective film to prevent the feed from adhering to the pipe wall. The first threshold can be set according to the feeding time of the marine ranch feeding system, the gas storage capacity of the gas storage tank, and the upper pressure limit. The first threshold is the gas storage tank pressure value that can still effectively form a high-pressure gas-water mixture at least at the end of the feeding time.

[0081] S3: If not, intermittently open the valves on the air storage tank and the water storage tank while the feeding outlet is open, and execute S4;

[0082] S4: Continuously obtain the pressure value in the gas storage tank. When the pressure value in the gas storage tank reaches a first threshold, open the valves on the gas storage tank and the water reservoir at the same time to clean the pipeline after feeding.

[0083] Based on the above method, when the pressure value in the gas tank is insufficient, during the feeding process, high-pressure gas-water mixture is intermittently sprayed to prevent feed adhesion, and when the pressure in the gas tank reaches the preset value, the pipeline is cleaned as soon as possible to maintain the cleanliness of the pipeline.

[0084] It should be noted that, during the pipeline cleaning process, when seawater flows out of the reservoir, it will naturally fall due to gravity. When the air pressure is insufficient, it can still clean the pipeline to a certain extent and prevent feed from sticking. Based on the above technical solution of the present invention, a pumping device can be further added. In extreme cases, the water reservoir can be replenished by generating electricity based on the feeding system.

[0085] Compared to existing technologies, this invention further utilizes a wave energy pressure amplification device to collect high-pressure gas and employs a control method that dynamically coordinates with gas storage conditions to control cleaning during the feeding process while being energy-efficient and environmentally friendly, thereby maintaining pipeline cleanliness. This control method can also be used to control pipeline cleaning in extreme situations involving the wave energy pressure amplification device, further improving the cleaning efficiency of the feeding system. In a more preferred embodiment, if cost is not a consideration, corresponding gas pressure equipment can be added to supplement the pressure in the gas storage tank when it is insufficient.

[0086] In a more preferred embodiment, if no additional pumping equipment is used to replenish water in extreme situations, the volume of water stored in the reservoir can be further determined in the above steps, that is, whether the volume of water stored in the reservoir meets the preset threshold is considered at the same time, and the injection mode of the high-pressure gas-water mixture is adjusted.

[0087] S1: When receiving the feeding command, open the feeding outlet;

[0088] S2: Obtaining the volume of seawater in the water reservoir and determining whether the volume of seawater in the water reservoir is greater than a second threshold value. If so, opening the valves on the gas tank and the water reservoir so that the high-pressure gas-water mixture sprayed from the high-pressure atomizing nozzle impacts the feed in the feeding pipe and forms an air-water film on the wall of the feeding pipe; and after the feeding outlet is closed, delaying for a preset time, closing the valves on the gas tank and the water reservoir to end feeding;

[0089] S3: If not, intermittently open the valves on the air storage tank and the water storage tank while the feeding outlet is open, and execute S4;

[0090] S4: After the feeding is completed, the volume of the seawater in the outlet pipe is continuously obtained. When the volume of the seawater reaches a second threshold, the valves on the gas storage tank and the water reservoir are opened simultaneously to clean the pipeline after feeding.

[0091] It should be noted that, similarly, the second threshold can be set based on the feeding time of the marine ranch feeding system, the volume of seawater in the reservoir, and the upper limit of the seawater volume. The second threshold is that at least at the end of the feeding time, there is still enough seawater to flush the feeding pipe.

[0092] In a more preferred embodiment, the volume of water stored in the water reservoir and the air pressure data in the air tank can be simultaneously considered and determined, including:

[0093] S1: When receiving the feeding command, open the feeding outlet;

[0094] S2: Obtaining the pressure value in the gas tank and the volume of seawater in the water reservoir, determining whether the pressure value in the gas tank is greater than a first threshold and whether the volume of seawater in the water reservoir is greater than a second threshold; if so, opening the valves on the gas tank and the water reservoir so that the high-pressure gas-water mixture sprayed from the high-pressure atomizing nozzle impacts the feed in the feeding pipe and forms an air-water film on the wall of the feeding pipe; and after the feeding outlet is closed, delaying a preset time, closing the valves on the gas tank and the water reservoir to end feeding;

[0095] S3: If not, then when the pressure value in the gas storage tank is greater than the first threshold or when the pressure value in the gas storage tank is not greater than the first threshold and the volume of seawater is not greater than the second threshold, execute step S4; when the volume of seawater in the water reservoir is greater than the second threshold, execute step S5;

[0096] S4: intermittently opening the valves on the gas storage tank and the water reservoir during the period when the feeding outlet is open. After the feeding is completed, continuously obtaining the volume of the seawater in the outlet pipe. When the seawater volume reaches a second threshold, simultaneously opening the valves on the gas storage tank and the water reservoir to clean the pipe after feeding, and then terminating the control.

[0097] S5: While the feeding outlet is open, the valve on the water tank is opened, and the valve on the gas tank is intermittently opened; after the feeding is completed, the pressure value in the gas tank is continuously obtained. When the pressure value in the gas tank reaches a first threshold, the valves on the gas tank and the water tank are opened at the same time to clean the pipeline after feeding.

[0098] The present invention organically integrates wave energy power generation, compressed air and pipeline cleaning, and can achieve feeding pipeline cleaning without the need for land-based energy, reducing the operating costs of marine ranches. In combination with Pascal's principle, a one-way valve is used to amplify pressure, converting low-grade wave energy into potential energy of air and seawater. The capacity utilization rate is high, and the air compression process is carried out below the sea surface, so the heat generated can be quickly diffused, improving the compression efficiency. After the compressed air enters the air storage tank, the intake airflow drives the turbine unit to perform work, making full use of the pressure difference between the internal and external air, and is suitable for popularization and use.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
