Description

Technical Field

[0001] This invention belongs to the field of aquaculture cage technology, and specifically relates to a multi-condition adaptive integrated semi-submersible truss cage. Background Technology

[0002] Aquaculture cages are artificial aquaculture facilities set up in natural waters (oceans, lakes, reservoirs, etc.). They form a relatively enclosed space through netting, providing a controlled growth environment for aquatic animals and are one of the important methods of intensive aquaculture.

[0003] Semi-submersible cages can submerge to the required depth to meet the needs of various working conditions. However, when using existing semi-submersible cages, many impurities from seawater will adhere to the inner wall of the ballast tank. Over time, this will reduce the volume of the ballast tank, affecting the injection of seawater and thus the submersion of the cage.

[0004] Therefore, it is necessary to invent a multi-condition adaptive integrated semi-submersible truss cage to solve the above problems. Summary of the Invention

One end of the third pull rope is fixedly connected to the rotating rod, and the other end passes through the inner wall of the mounting cavity and is fixedly connected to the scraper ring.

[0009] Furthermore, the capture assembly includes: a ring network, a pump body, a battery, a ring cavity, a circular hole, and a power cord; The ring mesh is fixedly installed inside the scraper ring. The ring cavity is opened inside the scraper ring. The circular holes are equidistantly arranged around the inside of the scraper ring and communicate with the ring cavity. The pump body is fixedly installed outside the scraper ring. The pumping end of the pump body communicates with the ring cavity. The power cord is embedded in the second pull rope. The battery is located outside the lower scraper ring. The battery supplies power to the lower pump body. The battery, together with the power cord, supplies power to the upper pump body.

[0010] Furthermore, the ring net is equidistantly arranged with a racket rod inside, and the inner walls on both sides of the ring net are provided with sliding grooves that cooperate with the racket rods. The two ends of the racket rod are slidably disposed in the sliding grooves. The side of the racket rod away from the ring net is fixedly connected to the inner wall of the sliding groove by a spring. The inner wall of the scraping ring is fitted with an adsorption element corresponding to the racket rod, and the adsorption element can attract the racket rod.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] This invention provides a multi-condition adaptive integrated semi-submersible truss cage, such as... Figures 1 to 6 As shown, the system includes a net cage 1 and a net cover 2. The net cover 2 is placed outside the net cage 1. Ballast tanks 3 are symmetrically arranged at the bottom of the net cage 1. The interior of the ballast tanks 3 is provided with horizontal compartments 4 and vertical compartments 5. The bottom of the ballast tanks 3 is provided with a discharge pipe 6. The interior of the discharge pipe 6 is provided with a filter screen 7. The top of the net cage 1 is provided with a channel communicating with the vertical compartments 5. Valves 8 are provided inside both the channel and the discharge pipe 6. The interior of the ballast tanks 3 is provided with a cleaning assembly for cleaning the inner walls of the horizontal compartments 4 and the vertical compartments 5.

[0019] When in use, to submerge, open the discharge pipe 6 and the valve 8 in the channel. After being filtered by the filter screen 7, the seawater enters the horizontal compartment 4 and the vertical compartment 5. With the injection of water, the ballast tank 3 becomes heavier, causing the net cage 1 to submerge. Close all valves 8, and the submersion stops, completing the submersion of the net cage 1. The submersion depth of the net cage 1 can be controlled by controlling the amount of water injected, adapting to various submersion depth requirements and meeting various working conditions. When drainage is required, open all valves 8 and inject gas into the ballast tank 3 through the channel. The gas pushes the seawater inside outward, completing the discharge of seawater. After completion, close all valves 8, and the net cage 1 floats to the surface. When the cage 1 needs to be floated, the cleaning components can clean the impurities attached to the inner walls of the horizontal compartment 4 and the vertical compartment 5. After cleaning, the cleaned impurities can be discharged into the sea along with the discharged seawater. By cleaning the horizontal compartment 4 and the vertical compartment 5, it is possible to prevent impurities from accumulating on the inner walls of the horizontal compartment 4 and the vertical compartment 5. Over time, this would cause the volume of the horizontal compartment 4 and the vertical compartment 5 to decrease, affecting its use.

[0020] like Figures 2 to 6 As shown, the cleaning assembly includes: a scraper ring 9, a first motor 10, a first pull rope 11, a second pull rope 12, a reset assembly, a capture assembly, and a second motor 19; Scraper rings 9 are respectively installed inside the horizontal compartment 4 and the vertical compartment 5. The outer side of the scraper rings 9 contacts the inner wall of the horizontal compartment 4 and the vertical compartment 5. The first motor 10 is fixedly installed in the middle of the top wall of the horizontal compartment 4. The output shaft of the first motor 10 is symmetrically provided with annular grooves. The inner wall of the annular grooves is connected to the adjacent scraper rings 9 through the first pull rope 11. One end of the second pull rope 12 is connected to the upper scraper ring 9, and the other end passes through the inner wall of the ballast tank 3 and is connected to the lower scraper ring 9. The reset assembly is respectively installed inside the vertical compartment 5 and the horizontal compartment 4 for resetting the scraper rings 9. The capture assembly is installed on the scraper rings 9 for capturing the cleaned impurities. Both ends of the filter screen 7 are fixedly installed with rotating shafts. The rotating shafts are rotatably installed on the inner wall of the discharge pipe 6. The second motor 19 is fixedly installed outside the discharge pipe 6. The output shaft of the second motor 19 is fixedly connected to one end of the rotating shaft on one side.

[0021] The first motor 10 is started, causing its output shaft to rotate forward, thereby winding the first pull rope 11. As the first pull rope 11 is wound, it causes the lower scraper ring 9 to move. The scraper ring 9 moves towards the discharge pipe 6, and in conjunction with the second pull rope 12, it pulls the upper scraper ring 9 downward. As the scraper ring 9 moves, it can scrape the impurities on the inner walls of the horizontal compartment 4 and the vertical compartment 5. During the scraping process, the scraped impurities are captured by the capture component. When the lower scraper ring 9 moves to the discharge pipe 6, the upper scraper ring 9 moves to the bottom of the vertical compartment 5. At this time, the first motor 10 is started, causing its output shaft to rotate in reverse, thereby releasing the first pull rope 11. The reset component pulls the corresponding scraper ring 9 to reset. After the scraper ring 9 is reset, the capture component stops capturing impurities. The second motor 19 is started, causing it to rotate with the rotating shaft and the filter screen 7, so that the filter screen 7 is in a vertical state. At this time, the water is discharged, and the impurities are discharged into the sea with the water, completing the cleaning of the horizontal compartment 4 and the vertical compartment 5. Then, the filter screen 7 is reset by the second motor 19.

[0022] By capturing impurities throughout the process, the impurities will not move to the inner wall of the side of the scraper ring 9 that is in contact with the horizontal compartment 4 or the vertical compartment 5 when the scraper ring 9 is reset, thus ensuring that the reset of the scraper ring 9 is not affected by impurities and that the scraper ring 9 can be reset smoothly.

[0023] like Figure 3 and Figure 4 As shown, the reset assembly includes: a rotating rod 13, a spring 14, and a third pull rope 15; Both the horizontal compartment 4 and the vertical compartment 5 are equipped with mounting cavities. The rotating rod 13 is rotatably installed in the mounting cavity. The spring 14 is sleeved on both ends of the rotating rod 13. The two ends of the spring 14 are fixedly connected to the rotating rod 13 and the inner wall of the mounting cavity, respectively. One end of the third pull rope 15 is fixedly connected to the rotating rod 13, and the other end passes through the inner wall of the mounting cavity and is fixedly connected to the scraper ring 9. The third pull rope 15 is wound up on the rotating rod 13.

[0024] When the scraper ring 9 moves, it works in conjunction with the third pull rope 15 to pull the rotating rod 13 to rotate in the forward direction, so that the third pull rope 15 is released. As the rotating rod 13 rotates, it causes the torsion spring 14 to twist and deform. When the first pull rope 11 is released, the torsion spring 14 returns to its original deformation and causes the rotating rod 13 to rotate in the reverse direction, so that the third pull rope 15 is wound up and the scraper ring 9 can be reset.

[0025] like Figure 3 As shown, the capture assembly includes: a ring network 16, a pump body 17, a battery 18, a ring cavity, a circular hole, and a power cord; The ring net 16 is fixedly installed on the inner side of the scraper ring 9. The ring cavity is opened inside the scraper ring 9. The circular holes are equidistantly arranged around the inner side of the scraper ring 9 and communicate with the ring cavity. The pump body 17 is fixedly installed on the outside of the scraper ring 9. The pump body 17 is a submersible pump in the prior art. The pumping end of the pump body 17 communicates with the ring cavity. The power cord is embedded in the second pull rope 12. The storage battery 18 is located on the outside of the lower scraper ring 9. The storage battery 18 supplies power to the lower pump body 17. The storage battery 18, together with the power cord, supplies power to the upper pump body 17. The storage battery 18 is a storage battery in the prior art that can be used underwater.

[0026] Start the pump body 17 to draw in water, and then discharge it back into the ballast tank 3 through its discharge end. As the pump body 17 draws in water, the water flows back into the ballast tank 3 through the ring net 16, the round hole, and the ring cavity, which generates suction at the ring net 16. The suction force causes the scraped impurities to be adsorbed onto the ring net 16, thus capturing the impurities. Turn off the pump body 17 to stop capturing the impurities.

[0027] like Figures 5 to 6 As shown, the ring net 16 is equidistantly arranged with racket rods 20 inside. The inner walls on both sides of the ring net 16 are provided with sliding grooves that cooperate with the racket rods 20. The two ends of the racket rods 20 are slidably arranged in the sliding grooves. The side of the racket rods 20 away from the ring net 16 is fixedly connected to the inner wall of the sliding groove by a spring 21. The inner wall of the scraper ring 9 is fitted with an adsorption element 22 corresponding to the racket rods 20. The adsorption element 22 can attract the racket rods 20.

[0028] After the capture of impurities stops, the adsorption element 22 adsorbs the flapper 20. The flapper 20 moves away from the ring net 16, causing the compression spring 21 to deform and release the adsorption element 22 from the flapper 20. The spring 21 resets and the flapper 20 quickly resets, causing it to beat the ring net 16 and shake the impurities captured on its surface away from the ring net 16. This allows the impurities to be discharged from the ballast chamber 3 more fully.

[0029] like Figure 6 As shown, the adsorption component 22 is specifically set as an underwater electromagnet, and the material of the handle 20 is martensitic stainless steel.

[0030] This allows the racket handle 20 to be used underwater for a long time. The adsorption element 22 is energized to make it magnetic, thus adsorbing the racket handle 20. When the adsorption element 22 is de-energized, it loses its magnetism and loses its adsorption on the racket handle 20.

[0031] When the lower scraper ring 9 moves to the discharge pipe 6, the upper scraper ring 9 can move to the bottom of the vertical compartment 5.

[0032] like Figure 3 As shown, the second pull rope 12 has a fluororubber sheath, and the power cord and multiple UHMWPE fiber bundles are arranged in parallel and wrapped together inside the second pull rope 12. The interior of the second pull rope 12 is filled with waterproof sealant.

[0033] This makes the second pull rope 12 have high tensile strength, which can meet the requirements of pulling the scraper ring 9. The power cord is not under force when the second pull rope 12 pulls the scraper ring 9, so that the power cord can transmit electricity normally.

[0034] The springs 14 and 21 are made of austenitic stainless steel.

[0035] This allows the spring 14 and spring 21 to be used underwater for extended periods.

[0036] The net cage 1 is equipped with a four-point mooring positioning system, a multi-energy complementary power supply system, a smart aquaculture monitoring system, and a central control system. The four-point mooring positioning system includes a GPS positioning module; the multi-energy complementary power supply system includes a 10kW wind power generation module, a 10kW photovoltaic power generation module, a 75kW diesel emergency power generation module, and a 200kWh energy storage battery module; the smart aquaculture monitoring system includes environmental monitoring sensors, fish school video monitoring equipment, and automatic feeding equipment; the central control system is connected to the ballast tank system, the mooring positioning system, the multi-energy complementary power supply system, and the smart aquaculture monitoring system. It achieves adaptive switching between three operating conditions and coordinated management and control of the entire system; the central control system is equipped with an operating condition switching trigger module, which can automatically or manually start the ballast tank loading adjustment process based on water temperature, dissolved oxygen and flow rate data collected by environmental monitoring sensors; the multi-energy complementary power supply system includes an energy management unit, which supports a tiered power supply logic that prioritizes photovoltaic and wind power supply, replenishes energy storage batteries and starts diesel generators for emergency use, and prioritizes emergency power supply to the ballast system, navigation equipment and monitoring equipment; the smart aquaculture monitoring system is connected to the shore-based workstation and cloud platform through 5G / dedicated line to realize real-time data transmission and remote management and control.

[0037] Working principle: When it is needed to submerge, open the discharge pipe 6 and the valve 8 in the channel. After the seawater is filtered by the filter screen 7, it enters the horizontal compartment 4 and the vertical compartment 5. With the injection of water, the ballast tank 3 becomes heavier, causing the net cage 1 to submerge. Close all valves 8, and the submersion stops, completing the submersion of the net cage 1. The submersion depth of the net cage 1 can be controlled by controlling the amount of water injected, adapting to various submersion depth requirements and meeting various working conditions. When it is necessary to drain water, open all valves 8 and inject gas into the ballast tank 3 through the channel. The gas pushes the seawater inside outward, completing the discharge of seawater. After completion, close all valves 8, and the net cage 1 floats to the surface. When it is necessary to float the cage 1 and clean the ballast tank 3, the pump body 17 is started to draw in water, which is then discharged back into the ballast tank 3 through its discharge end. As the pump body 17 draws in water, the water flows through the ring net 16, the round hole, and the annular cavity back into the ballast tank 3, generating suction at the ring net 16. The first motor 10 is started to rotate its output shaft forward, thereby winding the first pull rope 11. As the first pull rope 11 is wound, it causes the lower scraper ring 9 to move. The scraper ring 9 moves towards the discharge pipe 6, and together with the second pull rope 12, it pulls the upper scraper ring 9 down. As the scraper ring 9 moves, it can scrape the impurities on the inner walls of the horizontal tank 4 and the vertical tank 5. During the scraping process, the suction generated at the ring net 16 captures the scraped impurities. The square scraper ring 9 moves to the discharge pipe 6. At this time, the upper scraper ring 9 moves to the bottom of the vertical compartment 5. Then, the first motor 10 is started to reverse its output shaft, so that the first pull rope 11 is released. The reset component pulls the corresponding scraper ring 9 to reset. After the scraper ring 9 is reset, the pump body 17 is turned off to cancel the capture of impurities. The second motor 19 is started to rotate the shaft and filter screen 7, so that the filter screen 7 is in a vertical state. At this time, the water is discharged, and the impurities are discharged into the sea with the water, completing the cleaning of the horizontal compartment 4 and the vertical compartment 5. Then, the filter screen 7 is reset by the second motor 19. By cleaning the horizontal compartment 4 and the vertical compartment 5, it is possible to avoid the accumulation of impurities on the inner wall of the horizontal compartment 4 and the vertical compartment 5. Over time, this will cause the volume of the horizontal compartment 4 and the vertical compartment 5 to decrease, affecting the use. Throughout the process, by capturing impurities, the impurities are prevented from moving to the inner wall of the side of the scraper ring 9 that is in contact with the horizontal compartment 4 or the vertical compartment 5 when the scraper ring 9 is reset, thus ensuring that the reset of the scraper ring 9 is not affected by impurities and that the scraper ring 9 can be reset smoothly. After the capture of impurities stops, the adsorption element 22 adsorbs the flapper 20. The flapper 20 moves away from the ring net 16, causing the compression spring 21 to deform and release the adsorption element 22 from the flapper 20. The spring 21 resets and the flapper 20 quickly resets, causing it to beat the ring net 16 and shake the impurities captured on its surface away from the ring net 16. This allows the impurities to be discharged from the ballast chamber 3 more fully.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
