Description

Technical Field

[0001] The invention relates to the technical field of cages, in particular to a movable column-stabilized bottom-sitting aquaculture cage. Background Art

[0002] Atlantic salmon is very popular in the international market due to its delicious meat and rich nutrition. However, Atlantic salmon is a cold-water highly migratory fish, mainly distributed in the waters where the Atlantic Ocean meets the Pacific Ocean and the Arctic Ocean. They adapt to lower water temperatures, usually between 10-18°C. Therefore, farming Atlantic salmon requires similar environmental conditions to ensure its healthy growth.

[0003] The overall structure of the existing aquaculture cages includes a frame, a float, a sinker, a net, a net cover and a cable. The structure is complex and cannot be sunk into the sea level as a whole. It can only be fixed in shallow sea areas and is not suitable for deep-sea aquaculture. Secondly, when feeding, the existing cages do not have the function of processing feed, and the feed often contains lumps, which are easily deposited at the bottom of the cage, making it difficult for marine organisms to detect and eat it, resulting in waste.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in Embodiment 433 of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0039] See also Figure 1-Figure 14 The present invention provides a movable column-stabilized bottom-seated aquaculture cage, including a mobile cage 1, feed processing equipment and aquaculture management platform 2. The mobile cage 1 has its own lifting and floating control capabilities, and can be towed and moved in offshore waters. When the mobile cage 1 is towed to a designated position, it can be bottom-seated in open waters for aquaculture operations, feed bag storage, feed feeding, and feed sinking prevention, while the aquaculture management platform 2 supports ships to realize feed transportation, fry placement, adult fish fishing, fishing net cleaning, material supply, and other functions.

[0040] Specifically, the mobile net cage 1 includes two pontoons 11, a net cage frame 12 fixed between the tops of the two pontoons 11, and a net cloth arranged inside the net cage frame 12. A central pump room 111 and a plurality of side ballast water tanks 112 are separated by a watertight bulkhead in the pontoons 11. A water pump ballast system for uniformly introducing or exporting seawater into or out of each side ballast water tank 112 is arranged in the central pump room 111. The present invention realizes lifting and lowering control and posture adjustment of the mobile net cage 1 by injecting or discharging seawater into the side ballast water tanks 112 through the water pump ballast system; for example, when the water pump ballast system injects seawater into the side ballast water tanks 112, the weight of the mobile net cage 1 increases and the mobile net cage 1 sinks; when the water pump ballast system discharges the side ballast water tanks 112, the weight of the mobile net cage 1 decreases and the mobile net cage 1 floats.

[0041] Each side ballast water tank 112 is connected to a ventilation pipe, and the ventilation pipe extends to a position above the aquaculture management platform 2 . The ventilation pipeline meets the ventilation needs when injecting or discharging ballast water in the side ballast water tank 112 .

[0042] The water pump ballast system includes 1 ballast water pump and 1 main fire pump. The ballast pump is a vertical self-priming centrifugal water pump, and the main fire pump is a vertical self-priming centrifugal water pump. The main fire pump can be used as an emergency standby ballast pump. When the mobile cage 1 sinks, the ballast water in multiple side ballast water tanks 112 can be sucked by the main fire pump or the ballast pump to adjust the sinking speed of the mobile cage 1 and level the mobile cage 1.

[0043] Furthermore, the mobile cage 1 is provided with a set of air-blowing liquid level telemetry system, which can remotely measure the liquid level of each side ballast water tank 112 and the draft of the four corners of the mobile cage 1. Among them, the air-blowing liquid level telemetry system is an existing technology, and its specific principle and structure are not elaborated here.

[0044] The breeding management platform 2 is arranged on the top of the cage frame 12; the feed processing equipment includes a feed feeding mechanism and an anti-sinking mechanism for preventing the feed from sinking to the bottom.

[0045] In this embodiment, the cage frame 12 includes a column structure and a strut structure. The column structure is combined with the strut structure to form a rectangular truss structure with an open top. The column structure includes a plurality of columns vertically fixed on the top of the pontoon 11, and the strut structure includes three layers of horizontal struts arranged between adjacent columns, and connecting rods arranged between adjacent horizontal struts.

[0046] In this embodiment, the breeding management platform 2 includes a main deck 21 arranged on the top of the cage frame 12, and a superstructure 22 arranged on the main deck 21. The superstructure 22 is provided with a rest room, a toilet, a control room, an engine room, a fuel tank, a battery room, a fresh water tank and a feed tank.

[0047] In this embodiment, there are two sets of feed feeding mechanisms, both of which are arranged on the main deck 21, which include bulk silos, feeders, air source devices, feed pipelines, electrical control cabinets, etc.

[0048] The feed feeding mechanism adopts pneumatic conveying, in which the feeding speed of the feeder is adjustable, which is 0-750kg / h±10% (single feeder); the feeder is equipped with 8 feeding ports. When installed 4m above the water surface, the horizontal spreading range radius is not less than 8 meters, and the spreading range is 70°-90° horizontal fan-shaped. The electrical control cabinet can set the feeding time (not less than 10 times at the same time), feeding speed, feeding port, feeding amount through the touch screen, and automatically complete the feeding work. At the same time, the manual mode is set to manually control the feeding.

[0049] During the breeding period, dead fish on the water surface are manually salvaged on the main deck, and dead fish underwater are manually collected by divers who enter through the movable openings of the underwater net.

[0050] In this specific embodiment, two high-definition wide-angle pan-tilt cameras are installed on the mobile cage columns to monitor the water surface of the aquaculture cage in real time. The camera should be equipped with a base, tilt and zoom, and the camera will cover the water surface area of ​​the cage. One monitoring camera is installed in each of the central pump cabin 111 and the feed cabin, and the installation position can view the main equipment and instruments in the cabin.

[0051] like Figure 1 and Figure 4 As shown, in this embodiment, a slag discharge space 3 is formed between a pair of pontoons 11; the feed anti-sinking mechanism is installed in the slag discharge space 3, and includes side plates 4 symmetrically fixed on opposite sides of adjacent pontoons 11, and water spray pipes 6 evenly arranged between the pair of side plates 4; wherein, a flip plate assembly 5 is arranged on both sides above the water spray pipe 6, and water spray holes 61 are evenly arranged on the upper half of the water spray pipe 6;

[0052] Combination Figure 3 and Fig.14 As shown, the flip plate assembly 5 includes a flip plate 52 and a driving structure 53. The flip plate 52 is rotatably mounted between a pair of side plates 4 via a rotating shaft 51. The driving structure 53 includes a structure for driving the flip plate 52 to switch between a first state and a second state around the rotating shaft 51. When the flip plate 52 is in the first state (refer to Fig.11 As shown in FIG. 1 ), the lower sides of the two flip plates 52 on both sides above the water spray pipe 6 abut against the outer wall of the water spray pipe 6 and are in an inverted eight-shaped shape, and the upper sides of the two flip plates 52 between the adjacent water spray pipes 6 abut against each other and are in a straight eight-shaped shape; when the flip plates 52 are in the second state, the plurality of flip plates 52 are in a vertical state (refer to FIG. 1 ). Fig. 9 shown).

[0053] During the breeding period, the flip plates 52 are driven by the driving structure 53 to rotate to the second state. At this time, several flip plates 52 are in a vertical state. During this period, the waste generated in the mobile cage 1 can be settled to the seabed through the gap between the flip plates 52 and the water spray pipe 6. During the feeding period, the flip plates 52 are driven by the driving structure 53 to rotate to the first state. At this time, the lower sides of the two flip plates 52 on both sides of the water spray pipe 6 are against the outer wall of the water spray pipe 6 and are in an inverted eight shape. The two flip plates 52 between adjacent water spray pipes 6 are in a vertical state. The upper sides of the plate 52 are in contact with each other and are in a straight figure eight shape, that is, a V-shaped area is formed above the water spray pipe 6 by the flip plate 52. When the feed settles, it will gather in the V-shaped area of ​​the water spray pipe 6. At this time, the water spray hole 61 of the water spray pipe 6 will spray water, and the water will carry the feed up, so that the feed will enter the mobile cage 1 for the fish in the cage to eat, avoiding waste. In addition, this design can also make the seawater at the bottom of the mobile cage 1 flow fully, thereby increasing the oxygen content of the seawater at the bottom of the mobile cage 1 and avoiding hypoxia caused by too many fish at the bottom of the mobile cage 1.

[0054] Considering the installation environment of the driving structure 53, if a conventional electric driving element is used to drive the rotation of the flip plate 52, it is necessary to consider the sealing, corrosion resistance and layout of the circuit line. Figure 5-Figure 14As shown, in this embodiment, a U-shaped channel 43 is formed inside the side plate 4, and the U-shaped channel 43 includes an upper channel 431 and a lower channel 432 which are parallel to each other, and a connecting channel 433 arranged between one end of the upper channel 431 and the lower channel 432;

[0055] A pair of side plates 4 are respectively a first side plate 41 and a second side plate 42, the connecting channels 433 in the first side plate 41 and the second side plate 42 are symmetrically arranged, and the first side plate 41 and the second side plate 42 are both provided with a water inlet 433 connected to an end of the upper channel 431 away from the connecting channel 433;

[0056] The flip plates 52 on both sides of the water spray pipe 6 are respectively a first flip plate 521 and a second flip plate 522, and the two ends of the rotating shaft 51 are respectively a passive end and an active end. The active end of the rotating shaft 51 of the first flip plate 521 extends to the upper channel 431 of the first side plate 41, in which the driving structure 53 is installed, and the active end of the rotating shaft 51 of the second flip plate 522 extends to the upper channel 431 of the second side plate 42, in which the driving structure 53 is installed;

[0057] The driving structure 53 includes a swing plate 531 fixed to the active end 511 and adapted to the upper channel 431, and a preload spring 532 arranged between the swing plate 531 and the top of the upper channel 431. When the flip plate 52 is in the first state, the preload spring 532 is compressed, the swing plate 531 is in a horizontal state, and there is a gap between the swing plate 531 and the bottom side of the lower channel 432. When the flip plate 52 is in the second state, the preload spring 532 is in a normal state, the swing plate 531 is in an inclined state, and the lower side of the swing plate 531 contacts the bottom side of the lower channel 432.

[0058] The plurality of water spray pipes 6 include a plurality of first water spray pipes 62 and second water spray pipes 63 that are spaced apart from each other. One end of the first water spray pipe 62 is connected to the lower channel 432 in the first side plate 41 ; one end of the second water spray pipe 63 is connected to the lower channel 432 in the second side plate 42 .

[0059] Based on the above design, during feeding, seawater is injected into the water inlet 433 of the first side plate 41 and the second side plate 42, and the seawater will flow along the first channel and impact the swing plate 531, causing the first flip plate 521 to rotate forward and the second flip plate 522 to rotate reversely, thereby causing the first flip plate 521 and the second flip plate 522 to rotate to the second form, so as to form a V-shaped area above the water spray pipe 6. After the seawater flows to the connecting channel 433, the seawater enters the second channel and is introduced into the first water spray pipe 62 and the second water spray pipe 63, and then is discharged from the water spray hole 61, so that the seawater entrains the feed to rise, and then the feed enters the mobile net cage 1 for the fish in the net cage to eat, thereby avoiding waste. When the injection of seawater into the water inlet 433 stops, under the action of the preload spring 532, the first flip plate 521 and the second flip plate 522 will rotate to the first form.

[0060] When seawater is injected into the water spray pipe 6 of the present invention, the seawater is used to drive the first flip plate 521 and the second flip plate 522 to rotate, so that the first flip plate 521 and the second flip plate 522 rotate to the first shape by themselves. When the injection of seawater into the water spray pipe 6 stops, the first flip plate 521 and the second flip plate 522 rotate to the second shape by themselves. The driving structure 53 has a simple structure and stable operation.

[0061] In this embodiment, the water pump ballast system includes a water injection pump assembly for injecting water into the corresponding water inlet 433 .

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
