DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] A marine aquaculture cage capable of being raised and lowered in different areas, such as Figure 1-4 As shown, it includes a column 1;

[0031] It also includes a mounting plate 2, a net box 3, an intercepting rod 3a, a transmission shaft 4, a traction rope 5 and a motor 6; two mounting plates 2 are slidably connected to two columns 1 respectively; all mounting plates 2 are fixedly connected to the net box 3; a number of intercepting rods 3a are equidistantly arranged at the lower part of the net box 3; the two columns 1 are rotatably connected to the transmission shaft 4; two traction ropes 5 are fixedly connected to the transmission shaft 4; the lower ends of the two traction ropes 5 are fixedly connected to a mounting plate 2 respectively; a motor 6 is bolted to one of the columns 1; the output shaft of the motor 6 is fixedly connected to the transmission shaft 4.

[0032] It also includes a power storage waterproof electric push rod 7 and a friction plate 8; each mounting plate 2 is respectively fixed with a power storage waterproof electric push rod 7; and each power storage waterproof electric push rod 7 is respectively fixed with a friction plate 8 at its telescopic end.

[0033] It also includes a scraper ring 9; a scraper ring 9 is fixedly connected to the upper and lower sides of each mounting plate 2, and the scraper ring 9 is configured to be conical to guide the dirt to the surroundings to prevent the cleaned dirt from being retained and re-attached to the column 1; each scraper ring 9 is slidably connected to the column 1.

[0034] When in use, the two columns 1 are driven into the seabed soil layer in the shallow sea area, and the transmission shaft 4 and the motor 6 are exposed to the water surface. When breeding, the cover of the net box 3 is opened, the farmed fish is put into the net box 3, and then the cover is closed. Then, the motor 6 is controlled to drive the transmission shaft 4 to rotate to release the traction rope 5. Under the gravity of the mounting plate 2 and the net box 3, the mounting plate 2 and the net box 3 will slide downward on the column 1, so that the net box 3 is lowered to the specified position for breeding; when the farmed fish is to be caught or checked, the motor 6 is controlled to drive the transmission shaft 4 to rotate to reel in the traction rope 5, and the traction rope 5 drives the mounting plate 2 and the net box 3 to slide upward on the column 1, so that the net box 3 rises to a position convenient for the staff to catch or check the farmed fish, and the staff can catch or check the farmed fish; through the limiting effect of the mounting plate 2 and the column 1, the net box 3 will not be violently shaken and offset by the disturbance of the water flow when rising and falling, so as to avoid causing stress response in the farmed fish and affecting their normal growth and reproduction;

[0035] When the ocean current surges and generates an upward-flowing water flow, the water flow will push the mounting plate 2 and the net cage 3 to slide upward on the column 1, which will cause a stress response in the farmed fish and affect their normal growth and reproduction; therefore, after the net cage 3 is lowered to the specified position, the power-storage waterproof electric push rod 7 is controlled to drive the friction plate 8 to move toward the column 1, so that the friction plate 8 contacts the column 1, and the friction force between the friction plate 8 and the column 1 is used to limit the net cage 3 from moving up and down, so as to avoid the upward-flowing water flow pushing the mounting plate 2 and the net cage 3 to slide upward on the column 1, thereby affecting the normal growth and reproduction of the farmed fish; when the net cage 3 is to be controlled to rise and fall, the power-storage waterproof electric push rod 7 is controlled in advance to drive the friction plate 8 away from the column 1, so that the friction plate 8 is separated from the column 1, and the battery in the power-storage waterproof electric push rod 7 can be disassembled and replaced;

[0036] After the column 1 is immersed in water for a long time, there will be dirt on its surface, such as seaweed, which reduces the friction between the friction plate 8 and the column 1, resulting in the upward flowing water flow may push the mounting plate 2 and the net cage 3 to slide upward on the column 1, affecting the normal growth and reproduction of the farmed fish; therefore, scraper rings 9 are arranged on the upper and lower sides of the mounting plate 2. When the position of the net cage 3 is adjusted, the scraper ring 9 moves with the mounting plate 2 and the net cage 3. When the scraper ring 9 moves in an arc, it will slide on the column 1 to scrape off the dirt on the column 1. The scraper ring 9 is set to a cone shape to divert the dirt to the surroundings to prevent the cleaned dirt from being retained and reattached to the column 1. In this way, dirt is avoided between the friction plate 8 and the column 1, the friction between the two is reduced, and the upward flowing water flow is avoided to push the mounting plate 2 and the net cage 3 to slide upward on the column 1, affecting the normal growth and reproduction of the farmed fish.

[0037] In addition, multiple groups of columns 1 can be driven into the seabed soil layer in the shallow sea area to install multiple cages 3. Each cage 3 can be raised and lowered individually to achieve zoned lifting of multiple cages 3. In this way, different types of fish can be cultured in each cage 3. The breeding depth and harvest time of different types of fish will be different. In this way, the position of the cage 3 can be independently adjusted according to the type of fish being cultured to carry out scientific breeding, and the multiple groups of columns 1 can be fixed to each other through connecting plates to improve the stability of the columns 1.

[0038] Example 2

[0039] On the basis of Example 1, Figure 1 and Figure 6-8 As shown, it also includes a column 21, a mounting frame 22, a collection box 23, a battery-storage waterproof electric push rod 24, a camera 25, a transmission shaft 26, a traction rope 27 and a motor 28; a column 21 is respectively arranged in front and behind the two columns 1; a mounting frame 22 is slidably connected to each of the two columns 21; two battery-storage waterproof electric push rods 24 are respectively fixedly connected to the two mounting frames 22; all the battery-storage waterproof electric push rods 24 on the same mounting frame 22 are commonly fixedly connected to a collection box 23; the two mounting frames 22 are slidably connected to a collection box 23 respectively; a camera 25 is fixedly connected to the upper part of each of the two collection boxes 23, and the camera 25 is configured as a diving camera; a transmission shaft 26 is connected to the two columns 21 for common rotation; two traction ropes 27 are fixedly connected to the transmission shaft 26; the two traction ropes 27 are fixedly connected to a mounting frame 22 respectively; a motor 28 is bolted to one of the columns 21; the output shaft of the motor 28 is fixedly connected to the transmission shaft 26.

[0040] A closing plate 29 is also included; a closing plate 29 is fixedly connected to each of the two mounting frames 22 .

[0041] During the breeding process, farmed fish will produce a large amount of excrement. If the excrement is not collected and cleaned regularly, it is easy to cause water quality deterioration, and the deteriorated water quality will affect the normal growth and reproduction of farmed fish; therefore, when in use, the column 21 is driven into the seabed soil layer in the shallow sea area, and two collecting boxes 23 are set below the net cage 3, so that the upper side of the collecting box 23 is in contact with the lower side of the net cage 3. During breeding, the friction between the friction plate 8 and the column 1 is used to limit the net cage 3 from moving up and down, thereby preventing the upward flowing water from pushing the mounting plate 2 and the net cage 3 to slide upward on the column 1, affecting the normal growth and reproduction of farmed fish. Normal growth and reproduction, so the net box 3 can limit the collection box 23 from moving upward, so as to prevent the upward flowing water from pushing the collection box 23 upward and affecting the normal growth and reproduction of the farmed fish; in order to prevent external organisms from entering the net box 3, the mesh of the net box 3 is finely arranged, and the finely arranged mesh can also prevent the excrement from flowing out of the net box 3, and because the mesh of the net box 3 is finely arranged, when the seawater impacts the net box 3, the water flow in the net box 3 will not surge violently, and there are multiple net boxes 3 installed, and the net box 3 located in the middle is less affected by the impact of seawater, so that most of the excrement of the farmed fish The waste will fall into the collection box 23 for collection. When the camera 25 observes that a large amount of waste has been collected in the collection box 23, the battery-storage waterproof electric push rod 24 is controlled to contract, and the battery-storage waterproof electric push rod 24 will drive the collection box 23 to move, so that the collection box 23 is moved away from the bottom of the net box 3. Then the motor 28 is controlled to drive the transmission shaft 26 to rotate and reel in the traction rope 27. The traction rope 27 drives the mounting frame 22 and the collection box 23 to slide upward on the column 21, so that the collection box 23 moves to the water surface. Then the staff cleans up the waste in the collection box 23, and then controls the motor 28 to rotate and reel in the traction rope 27. 28 drives the second transmission shaft 26 to rotate and release the second traction rope 27. Under the gravity of the mounting frame 22 and the collecting box 23, the mounting frame 22 and the collecting box 23 will slide downward on the second column 21, so that the collecting box 23 slides down to the bottom of the net box 3. The position of the collecting box 23 can be monitored by the camera 25, and then the second storage waterproof electric push rod 24 is controlled to extend. The second storage waterproof electric push rod 24 will drive the collecting box 23 to move, so that the collecting box 23 moves to the bottom of the net box 3 again to continue to collect the excrement of the farmed fish. The battery in the second storage waterproof electric push rod 24 can be disassembled and replaced;

[0042] When the traction rope 27 drives the mounting frame 22 and the collecting box 23 to slide upward on the column 21, part of the excrement in the collecting box 23 will overflow due to the influence of the water flow, causing the water quality to deteriorate; therefore, a closing plate 29 is provided. When the battery-powered waterproof electric push rod 24 drives the collecting box 23 to move, so that the collecting box 23 is moved away from the bottom of the net box 3, the collecting box 23 will move to the bottom of the closing plate 29, and the closing plate 29 will block the opening of the collecting box 23, thereby preventing part of the excrement in the collecting box 23 from overflowing due to the influence of the water flow, causing the water quality to deteriorate.

[0043] Example 3

[0044] On the basis of Example 2, Figure 4 , Figure 5 , Figure 7 and Fig. 9 As shown, the interception bar 3a on the net box 3 is arranged in a V shape.

[0045] It also includes a connecting rod 31 and a baffle 32; a connecting rod 31 is fixedly connected to the middle of the net box 3; two baffles 32 are connected to the connecting rod 31 through a torsion spring, and the upper part of the baffle 32 is set to be conical to prevent waste accumulation.

[0046] It also includes a connecting rod 2 33 and a limiting plate 34; two connecting rods 2 33 are fixedly connected to the middle of the net box 3, and the two connecting rods 2 33 are symmetrically arranged front and back; the middle of the two connecting rods 2 33 is connected to a limiting plate 34 through a torsion spring.

[0047] During the breeding process, if the farmed fish dies, the fish bladder loses its regulating function and the fish body becomes stiff. Therefore, the farmed fish will sink to the bottom of the water when it just dies. After autolysis and corruption, some gas is produced and the density is reduced, and the farmed fish will float up. In this way, the farmed fish that has just died will fall on the interception rod 3a. The interception rod 3a is set in a V shape, so the farmed fish that has just died will slide down to the baffle 32 in the middle. The gravity of the dead farmed fish will force the baffle 32 to rotate around the connecting rod 1 31 and become tilted, so that the dead fish will float up. The dead farmed fish pass through the gap between the baffle plate 32 and the intercepting rod 3a and fall into the collection box 23. After passing through, due to the elastic force of the torsion spring between the baffle plate 32 and the connecting rod 31, the baffle plate 32 will rotate back and reset to prevent the live fish from escaping through the gap between the baffle plate 32 and the intercepting rod 3a. After the camera 25 detects the dead farmed fish, it immediately controls the collection box 23 to move to the water surface, so that the staff can immediately analyze the dead farmed fish to confirm the cause of death, so as to take corresponding protective measures in time to ensure the healthy growth of the farmed fish.

[0048] When cleaning the excrement in the collecting box 23, and when collecting dead farmed fish in the collecting box 23, it is necessary to move the collecting box 23 from the bottom of the net cage 3 so that the collecting box 23 is moved to the water surface. At this time, the collecting box 23 is not under the net cage 3, and some farmed fish may swim to the lower part of the net cage 3 and trigger the baffle plate 32 to rotate, causing the farmed fish to pass through the gap between the baffle plate 32 and the intercepting rod 3a, escape from the net cage 3, and cause the loss of farmed fish; therefore, a limit plate 34 is provided. In the initial state, the limit plate 34 is held in a vertical state by the collecting box 23. When the collecting box 23 is moved away from the bottom of the net cage 3, due to the elastic force of the torsion spring, the limit plate 34 will rotate around the connecting rod 23 to a state close to the horizontal state, and finally Fig. 9As shown, the limit plate 34 is against the lower side of the net cage 3, which plays a role in limiting the rotation of the baffle 32, thereby preventing the farmed fish from triggering the rotation of the baffle 32, causing the farmed fish to pass through the gap between the baffle 32 and the intercepting rod 3a, escape from the net cage 3, and cause the loss of farmed fish; the end of the limit plate 34 will protrude from the net cage 3, so that when the collection box 23 moves to the bottom of the net cage 3, it will drive the limit plate 34 to rotate and reset.
