Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to aquaculture equipment. Background Art

[0002] In industrial aquaculture, the kinetic energy generated by water movement—from fish swimming, currents and waves, and bubbles generated by aeration processes—is often overlooked, resulting in significant energy waste. Because this kinetic energy is generated irregularly, distributed unevenly, and exhibits variable and low-frequency characteristics, it cannot be captured and utilized by traditional generators. Therefore, achieving efficient capture and utilization of this kinetic energy remains a significant challenge within existing technologies.

[0003] Furthermore, in industrial aquaculture, the level of dissolved oxygen in the water environment is directly related to the survival of aquatic products. Low-intensity electric field oxygenation technology has the advantages of low power consumption, low energy consumption, and no pollution, and has good application prospects in aquaculture.

[0039] The following combination Figure 1-Figure 3 An aquaculture device according to an embodiment of the present invention is described.

[0040] Figure 1 The three-dimensional structure diagram of the aquaculture equipment provided by the embodiment of the present invention is illustrated as follows: Figure 1 As shown, the aquaculture equipment includes a culture tank 100, an electric field component 200, and an oxygenation component 300. The culture tank 100 is provided with a water inlet 110. The electric field component 200 is disposed within the culture tank 100 and is used to convert kinetic energy generated by the movement of the water into electrical energy. It also forms an electric field within the water, thereby changing the polarity of water molecules and thereby increasing the water's oxygen solubility. The oxygenation component 300 is disposed within the culture tank 100 and is used to deliver oxygen into the water.

[0041] The aquaculture equipment provided by the embodiment of the present invention injects water into the breeding barrel 100 through the water inlet 110 for aquaculture. The electric field component 200 can convert the kinetic energy generated by the movement of the water body due to the movement of fish, water waves, and bubbles generated by the aeration process into electrical energy, and form an electric field in the water body to change the polarity of water molecules, thereby increasing the oxygen dissolving capacity of the water body. By cooperating with the electric field component 200 and the oxygenation component 300, on the one hand, the oxygen content of the water body can be increased, thereby improving the efficiency of aquaculture; on the other hand, the electric field component 200 efficiently collects and utilizes the kinetic energy generated by the movement of the water body to form an electric field, without the need for an additional power supply, thus saving energy and reducing emissions, and reducing the cost of aquaculture.

[0042] Figure 2 One of the main structural diagrams of the electric field assembly provided by an embodiment of the present invention is illustrated. Figure 3 The second schematic diagram of the main structure of the electric field component provided by the embodiment of the present invention is illustrated. Figure 2 and Figure 3 As shown, the aquaculture equipment includes multiple electric field components 200, each of which includes an electric field assembly 210. The electric field assembly 210 includes a suspended ball 211, an inner ball 212, and a tumbler body 213. A first accommodating space is provided inside the suspended ball 211, which is suspended in the water body. The outer surface of the suspended ball 211 is provided with a first electric field generating electrode (not shown in the figure) and a second electric field generating electrode (not shown in the figure). The inner ball 212 is provided in the first accommodating space and is connected to the inner surface of the suspended ball 211. The inner surface of the inner ball 212 is provided with a second accommodating space. The tumbler body 213 is provided in the second accommodating space. One of the inner surface of the inner ball 212 and the outer surface of the tumbler body 213 is provided with a positive friction induction electrode 214, and the other is provided with a negative friction induction electrode 215. The tumbler body 213 is configured to reciprocate under the action of an external force, causing the positive friction induction electrode 214 and the negative friction induction electrode 215 to generate electricity through friction. The positive friction-sensing electrode 214 is connected to the first electric field-generating electrode via a first wire, while the negative friction-sensing electrode 215 is connected to the second electric field-generating electrode via a second wire. The inner ball 212 can be attached to the inner surface of the suspension ball 211 by adhesive bonding. The suspension ball 211, inner ball 212, and tumbler body 213 can be made of a flexible thermoplastic material, which simplifies the manufacturing process and reduces costs.

[0043] When waves, fish swimming, and aeration bubbles in the water environment cause the suspended ball 211 to shake, the suspended ball 211 drives the tumbler body 213 to move. When the tumbler body 213 moves, due to the action of an external force, the external force generates a torque on the contact point between the tumbler and the surface, causing the tumbler to tilt and disrupt its original balance. The hemisphere rolls to one side, and the contact point moves therewith, forming a new contact point, that is, a new central axis. At this time, the line of action of gravity and the original central axis are not in the same straight line, thus forming a resistance force. The external force and the resistance force act together on the tumbler body 213, causing the tumbler body 213 to reciprocate under the action of the external force. When the outer surface of the tumbler body 213 contacts the inner surface of the inner ball 212, the positive friction induction electrode 214 and the negative friction induction electrode 215 compress each other; when the outer surface of the tumbler body 213 moves away from the inner surface of the inner ball 212, the positive friction induction electrode 214 and the negative friction induction electrode 215 rebound and return to an incompletely compressed state, causing the positive friction induction electrode 214 and the negative friction induction electrode 215 to generate electricity through friction, realizing the conversion of kinetic energy into electrical energy. The current is conducted to the first electric field generating electrode through the first wire, and the current is conducted to the second electric field generating electrode through the second wire, forming a low-voltage electric field between the second electric field generating electrode and the first electric field generating electrode. The low-voltage electric field changes the polarity of water molecules, thereby increasing the oxygen dissolving capacity of the water body.

[0044] In an embodiment of the present invention, a positive friction sensing electrode 214 is provided on the inner surface of the inner ball 212, and a negative friction sensing electrode 215 is provided on the outer surface of the tumbler body 213. The vertical height of the negative friction sensing electrode 215 is greater than the vertical height of the positive friction sensing electrode 214. Alternatively, the negative friction sensing electrode 215 is provided on the inner surface of the inner ball 212, and the positive friction sensing electrode 214 is provided on the outer surface of the tumbler body 213. The vertical height of the negative friction sensing electrode 215 is less than the vertical height of the positive friction sensing electrode 214.

[0045] When a positive friction induction electrode 214 is provided on the inner surface of the inner ball 212 and a negative friction induction electrode 215 is provided on the outer surface of the tumbler body 213, by making the vertical height of the negative friction induction electrode 215 greater than the vertical height of the positive friction induction electrode 214, it is possible to ensure that the negative friction induction electrode 215 and the positive friction induction electrode 214 are in complete contact and compression, thereby improving the efficiency of friction power generation between the positive friction induction electrode 214 and the negative friction induction electrode 215.

[0046] When a negative friction induction electrode 215 is provided on the inner surface of the inner ball 212 and a positive friction induction electrode 214 is provided on the outer surface of the tumbler body 213, by making the vertical height of the negative friction induction electrode 215 smaller than the vertical height of the positive friction induction electrode 214, it is also possible to ensure that the negative friction induction electrode 215 and the positive friction induction electrode 214 are in complete contact and compression, thereby improving the efficiency of friction power generation between the positive friction induction electrode 214 and the negative friction induction electrode 215.

[0047] In an embodiment of the present invention, the inner surface of the inner ball 212 is provided with positive friction sensing electrodes 214 symmetrically along the center of the ball, and the outer surface of the tumbler body 213 is provided with negative friction sensing electrodes 215 symmetrically along the central axis. Alternatively, the inner surface of the inner ball 212 is provided with negative friction sensing electrodes 215 symmetrically along the center of the ball, and the outer surface of the tumbler body 213 is provided with positive friction sensing electrodes 214 symmetrically along the central axis.

[0048] When the inner surface of the inner ball 212 is provided with positive friction induction electrodes 214 symmetrical along the center of the ball, and the outer surface of the tumbler body 213 is provided with negative friction induction electrodes 215 symmetrical along the central axis, as the tumbler body 213 reciprocates under the action of external force, the positive friction induction electrodes 214 on both sides of the ball center and the corresponding negative friction induction electrodes 215 on both sides of the central axis can generate electricity through friction, thereby improving the energy conversion efficiency of converting kinetic energy into electrical energy.

[0049] When the inner surface of the inner ball 212 is provided with negative friction induction electrodes 215 symmetrical along the center of the ball, and the outer surface of the tumbler body 213 is provided with positive friction induction electrodes 214 symmetrical along the central axis, as the tumbler body 213 reciprocates under the action of external force, the negative friction induction electrodes 215 on both sides of the ball center and the corresponding positive friction induction electrodes 214 on both sides of the central axis can generate electricity through friction, which can also improve the energy conversion efficiency of converting kinetic energy into electrical energy.

[0050] In an embodiment of the present invention, the positive friction sensing electrode 214 is made of silicone material, and the negative friction sensing electrode 215 is made of conductive nickel cloth. The positive friction sensing electrode 214 and the negative friction sensing electrode 215 can be fixed by gluing.

[0051] In an embodiment of the present invention, the first electric field generating electrode and the second electric field generating electrode are made of copper. The first electric field generating electrode and the second electric field generating electrode can be attached to the outer surface of the suspension ball 211 by pasting or coated on the outer surface of the suspension ball 211 in the form of a copper film.

[0052] In an embodiment of the present invention, the electric field assembly 210 further includes a coil 216. A third accommodation space is provided within the tumbler body 213, and the coil 216 is disposed within the third accommodation space. Two magnetic poles 217 are provided on the inner surface of the suspension ball 211, or a magnetic pole 217 is provided on the inner surface of the suspension ball 211 and the inner surface of the inner ball 212, respectively. The coil 216 is located between the two magnetic poles 217, enabling the coil 216 to cut the magnetic induction lines. The first electric field generating electrode is connected to one magnetic pole 217 via a third conductor, and the second electric field generating electrode is connected to the other magnetic pole 217 via a fourth conductor.

[0053] When waves, fish swimming, and aeration bubbles in the water environment cause the suspended ball 211 to shake, the suspended ball 211 drives the tumbler body 213 to move, causing the tumbler body 213 to reciprocate under the action of an external force. Driven by the tumbler body 213, the coil 216 disposed in the third accommodation space moves to cut the magnetic flux lines, converting kinetic energy into electrical energy. One magnetic pole 217 conducts current to the first electric field generating electrode via a third conductor, and the other magnetic pole 217 conducts current to the second electric field generating electrode via a fourth conductor, forming a low-voltage electric field between the second electric field generating electrode and the first electric field generating electrode. The low-voltage electric field changes the polarity of water molecules, thereby increasing the oxygen dissolving capacity of the water body.

[0054] In the embodiments of the present invention, electromagnetic induction and triboelectric generation operate independently, generating electricity without interfering with each other, and transmit the electrical energy to the first and second electric field generating electrodes. In other words, the aquaculture equipment of the present invention utilizes tribo-electromagnetic coupling to achieve full-band energy collection, generate a low-voltage electric field, change the polarity of water molecules, and increase the water's ability to dissolve oxygen.

[0055] In an embodiment of the present invention, the electric field assembly 210 further includes a fixing post 218 disposed in the third accommodation space. Both ends of the fixing post 218 are connected to the inner wall of the tumbler body 213, and the coil 216 is wound around the fixing post 218. The fixing post 218 secures the coil 216, allowing it to stably cut through the magnetic flux lines, thereby converting kinetic energy into electrical energy.

[0056] In an embodiment of the present invention, the electric field component 200 also includes an elastic component 220, and two adjacent electric field components 210 are connected by the elastic component 220, and the electric field component 210 located at the bottom is connected to the bottom of the breeding bucket 100. By providing the elastic component 220, the electric field component 210 can collect and utilize the kinetic energy generated by the movement of the water body in different directions, thereby improving the efficiency of kinetic energy utilization. Multiple electric field components 210 can be connected through the elastic component 220, so that multiple electric field components 210 can collect and utilize kinetic energy at different heights of the water body. Multiple electric field components 200 can also be set at different positions at the bottom of the breeding bucket 100 through the elastic component 220 to collect and utilize kinetic energy at different positions. The elastic component 220 may include a spring, and the spring is used to achieve the connection between two adjacent electric field components 210.

[0057] In an embodiment of the present invention, the oxygenation component 300 includes a micro-nano aeration tube 310. The aeration tank 100 is provided with an aeration inlet 120, and the micro-nano aeration tube 310 is connected to the aeration inlet 120. Because the bubbles generated by the micro-nano aeration tube 310 have a small diameter, a long residence time in the water body, and a large contact area with the water body, the micro-nano aeration tube 310 can improve the oxygenation effect on the water body.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
