Description

Technical Field

[0001] The present invention relates to the technical field of deep-sea aquaculture, in particular to a wind and wave resistant deep-sea aquaculture cage. Background Art

[0002] Marine aquaculture cages, particularly deep-sea aquaculture cages, are crucial facilities for aquaculture of fish and other aquatic organisms in modern marine fisheries. They are used for large-scale fish farming in open waters or semi-enclosed bays. This aquaculture method not only improves production efficiency per unit area but also helps alleviate pressure on the nearshore environment, providing opportunities for sustainable development. Existing deep-sea aquaculture cages accumulate various deposits on their nets over time, significantly reducing their permeability. In the event of wind and waves, the presence of these deposits significantly increases the resistance to water flow, making the nets more susceptible to damage.

[0003] To address this issue, a common method currently used is to flush the nets with nozzles to remove debris. However, because water resistance is much greater than air resistance, this method has significant drawbacks: the nozzles have a limited underwater range, making it difficult to effectively clean the net surface. This is especially true for larger aquaculture cages, where cleaning results are often unsatisfactory and the problem of debris affecting the net's permeability remains difficult to resolve. Summary of the Invention

[0004] In view of the above-mentioned prior art, the present invention provides a wind and wave resistant deep-sea aquaculture cage, which can more effectively remove attachments on the net and improve the water permeability and wind and wave resistance of the cage.

[0005] To achieve the above-mentioned purpose, the technical solution of the embodiment of the present invention is implemented as follows:

[0006] A wind and wave resistant deep-sea aquaculture cage comprises a cage body, the net of the cage body is provided with a tightening line, the tightening line is used to tighten the net inward and gradually increase the inner diameter of the net from bottom to top, the longitudinal cross-sectional contour line of the net is an arc line, the bottom of the net is provided with a jet tube and a bubble tube, the outlet directions of the jet tube and the bubble tube are upward, the bubble tubes are provided on both sides of the jet tube, the jet tube is connected to a water pump, and the bubble tube is connected to an air pump.

[0007] Furthermore, the net cage body includes a floating frame, a net and an anchor, the anchor is fixed to the seabed, the floating frame floats on the water surface, the top of the net is connected to the floating frame, and the anchor is connected to the bottom of the net.

[0008] Furthermore, the anchor is connected to the net through a traction rope, and a reinforcement frame is provided at the bottom of the net, and the reinforcement frame is connected to the traction rope.

[0009] Furthermore, the jet tube and the bubble tube are also provided in the lower middle part and / or the middle part and / or the upper middle part of the net.

[0010] Furthermore, the tangent of the lower end of the longitudinal cross-sectional contour of the net is A, the tangent of the upper end of the longitudinal cross-sectional contour is B, and the line connecting the upper and lower ends of the longitudinal cross-sectional contour is C. The longitudinal cross-sectional contour is located in the area enclosed by the tangents A, B and C, and from bottom to top, the angle between the tangent of the longitudinal cross-sectional contour and the water surface gradually decreases.

[0011] Furthermore, a reinforcement rod is provided on the side of the net, the upper end of the reinforcement rod is connected to the floating frame, and the lower end of the reinforcement rod is connected to the reinforcement frame. The reinforcement rod matches the longitudinal profile contour line of the net, and the reinforcement rod is provided with a support rod, and the jet tube and bubble tube are fixed on the support rod.

[0012] Furthermore, the jet tube includes a water pipe body and a water outlet needle tube, and the water outlet needle tube is connected to the water pipe body.

[0013] Furthermore, the water outlet needle tube is L-shaped, the horizontal part of the water outlet needle tube is connected to the water pipe body, the vertical part of the water outlet needle tube is located in a double trumpet-shaped cover, and the double trumpet-shaped cover includes an upper trumpet cover, a lower trumpet cover and a cylindrical tube connecting the upper trumpet cover and the lower trumpet cover, the vertical part of the water outlet needle tube is located in the cylindrical tube, and the water outlet needle tube passes through the double trumpet-shaped cover and then connects to the water pipe body.

[0014] Furthermore, the bubble tube includes a tracheal body and an air outlet needle tube, the air outlet needle tube is in an inverted Y shape, one end of the bottom of the air outlet needle tube is connected to the tracheal body, and the other end of the bottom is connected to seawater or a water pump.

[0016] The beneficial effects of the present invention are as follows: the net of the cage body is tightened by a tightening line, which improves the structural strength of the net and is not easily deformed when encountering wind and waves. The cage is impacted by high-pressure water flow, which further cleans the attachments on the net, improves the water permeability of the net, and further improves the wind and wave resistance of the net. In the process of the jet tube spraying upward, the shape of the net of the present invention enables the jet tube at the bottom to act on a larger area, thereby improving the effect of cleaning attachments.

[0024] Please refer to the attached Figures 1 to 3The present application provides a wind- and wave-resistant deep-sea aquaculture cage, comprising a cage body 1. A net 3 of the cage body 1 is provided with a tightening line 2. The tightening line 2 is used to tighten the net 3 inward and gradually increase the inner diameter of the net 3 from bottom to top. The longitudinal cross-sectional profile of the net 3 is an arcuate line. A jet tube 4 and a bubble tube 5 are provided at the bottom of the net 3. The outlets of the jet tube 4 and the bubble tube 5 face upward. The bubble tubes 5 are provided on both sides of the jet tube 4. The jet tube 4 is connected to a water pump 6, and the bubble tube 5 is connected to an air pump 7. The net 3 of the cage body 1 is tightened by the tightening line 2, which increases the structural strength of the net 3 and prevents deformation in wind and waves. Optionally, the tightening line 2 is elastic. A jet tube 4 and a bubble tube 5 are provided at the bottom of the net 3. After high-pressure water generated by a high-pressure water pump 6 is delivered to the jet tube 4, the high-pressure water is ejected through the jet tube 4, impacting the net cage with the high-pressure water flow, further cleaning the attached objects on the net 3, improving the water permeability of the net 3, and further enhancing the net 3's wind and wave resistance. During the upward spraying process of the jet tube 4, the shape of the net 3 of the present invention enables the jet tube 4 at the bottom to act on a larger area, improving the cleaning effect of attached objects. More importantly, while the high-pressure water flow is being sprayed, high-pressure air generated by the high-pressure air pump 7 is delivered to the bubble tube 5, and bubbles are ejected through the bubble tube 5. The ejected bubbles are located on both sides of the high-pressure water flow, have the characteristic of upward flow, and simultaneously serve to isolate the high-pressure water flow from the surrounding static water flow, thereby increasing the range of the high-pressure water flow and more effectively cleaning attached objects on the net 3.

[0025] Specifically, the net cage body 1 includes a buoyancy frame 8, a net 3, and an anchor 9. The anchor 9 is fixed to the seabed, and the buoyancy frame 8 floats on the water surface. The top of the net 3 is connected to the buoyancy frame 8, and the anchor 9 is connected to the bottom of the net 3. The buoyancy frame 8 floats on the sea surface, providing an upward pulling force for the net 3, and the anchor 9 is fixed to the seabed, providing a downward pulling force for the net 3, thereby pulling the net 3 apart in the water.

[0026] Specifically, the anchor 9 is connected to the net 3 via a traction rope 10. A reinforcement frame 11 is provided at the bottom of the net 3, and the reinforcement frame 11 is connected to the traction rope 10. The reinforcement frame 11 improves the structural strength of the bottom of the net 3 and ensures that the bottom of the net 3 is evenly stressed.

[0027] Optionally, jet tubes 4 and bubble tubes 5 are also provided in the lower middle portion, middle portion, and / or upper middle portion of the net 3. The outlets of the jet tubes 4 and bubble tubes 5 face upward, and the bubble tubes 5 are provided on both sides of the jet tube 4. The jet tube 4 is connected to a water pump 6, and the bubble tubes 5 are connected to an air pump 7. By providing the jet tubes 4 and bubble tubes 5 in different locations, the cleaning effect on attached objects is improved.

[0028] Specifically, the lower tangent line of the longitudinal cross-section of the net 3 is A, the upper tangent line is B, and the line connecting the upper and lower ends of the longitudinal cross-section is C. The longitudinal cross-section lies within the area enclosed by tangents A, B, and C, and the angle between the tangent line and the water surface decreases from bottom to top. When the jet tube 4 ejects high-pressure water upward, the fast-flowing water can more effectively impact debris attached to a larger area of ​​the net 3, improving the net's permeability and thus its ability to withstand wind and waves. The shape of the net 3 also reduces resistance to ocean currents.

[0029] Specifically, a reinforcement rod 12 is provided on the side of the net 3. The upper end of the reinforcement rod 12 is connected to the floating frame 8, and the lower end of the reinforcement rod 12 is connected to the reinforcement frame 11. The reinforcement rod 12 matches the longitudinal cross-sectional contour of the net 3. The reinforcement rod 12 is provided with a support rod 13, and the jet tube 4 and the bubble tube 5 are fixed to the support rod 13. The reinforcement rod 12 further improves the stability of the net 3. The support rod 13 provided on the reinforcement rod 12 can also fix the jet tube 4 and the bubble tube 5, facilitating the coordinated action of the jet tube 4 and the bubble tube 5 to remove debris attached to the net 3.

[0030] Specifically, the jet pipe 4 includes a water pipe body 14 and a water outlet needle 15, which is connected to the water pipe body 14. The high-pressure water in the water pipe body 14 is discharged from the water outlet needle 15 to form a jet, and the high-speed water flow impacts the water pipe body 14.

[0031] Optionally, the water outlet needle tube 15 is L-shaped, with the horizontal portion of the water outlet needle tube 15 communicating with the water pipe body 14. The vertical portion of the water outlet needle tube 15 is located within a double trumpet-shaped cover 16. The double trumpet-shaped cover 16 includes an upper trumpet cover 17, a lower trumpet cover 18, and a cylindrical tube 19 connecting the upper trumpet cover 17 and the lower trumpet cover 18. The vertical portion of the water outlet needle tube 15 is located within the cylindrical tube 19. The water outlet needle tube 15 passes through the double trumpet covers and then connects to the water pipe body 14. The water jetted from the water outlet needle tube 15 passes through the cylindrical tube 19, and its upward jetting drives the water in the cylindrical tube 19 to flow upward, thereby increasing the overall water flow rate. The lower trumpet cover 18 at the bottom of the cylindrical tube 19 provides supplementary flow. When the water flows through the upper trumpet cover 17, due to the wall effect of the fluid, the outflow range is fan-shaped, thereby increasing the flushing area of ​​the net 3.

[0032] Specifically, the bubble tube 5 includes a tracheal body 20 and an air outlet needle 21. The air outlet needle 21 is in an inverted Y-shape, with one end at the bottom of the air outlet needle 21 connected to the tracheal body 20 and the other end connected to seawater or a water pump 6. Multiple air outlet needles 21 are provided on the tracheal body 20. High-pressure air is discharged from the air outlet needles 21. When the gas flows rapidly, seawater is drawn in from the bottom, forming interlaced air and water columns at the top of the air outlet needles 21. Ultimately, these interlaced air and water columns are discharged from the air outlet needles 21. This design effectively prevents gas explosions, specifically, when the gas pressure or velocity is high, it prevents the gas from forming large bubbles at the outlet. It effectively forms multiple bubbles on both sides of the jet, which helps to increase the jet's water range. In addition to being drawn in from seawater, the water entering the air outlet needles 21 can also be water pumped by an external water pump 6, or water pumped by the water pump 6 connected to the water tube body 14 of the present invention.

[0033] Optionally, the floating frame is provided with a plurality of vibrators 22. When the vibrators 22 are turned on, they drive the net 3 to vibrate up and down, and the impact of the water flow and bubbles is coupled. That is, when the net 3 vibrates upward, the jet tube 4 and the bubble tube 5 also move upward, thereby increasing the initial velocity of the water flow and bubbles. When the net 3 vibrates downward, the water flow and bubbles move upward, and their movement speeds are opposite, which increases the impact on the net 3, thereby facilitating the removal of attached objects on the net 3.

[0034] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. The scope of protection of the present invention should be based on the scope of protection of the claims.
