Description

[0001] A low-cost, long-life, wind and wave-resistant, automatic feeding aquaculture cage, which involves the aquaculture cage technology.

[0002] Technical background of this case:

[0003] With the serious decline of my country's offshore natural fishery resources and the country's demand for marine economic development and food, the development of deep-water wind and wave resistant cages is an inevitable path for the sustainable development of my country's marine aquaculture industry. The wind and wave resistant cages currently in use mainly include floating HDPE round cages, floating HDPE square cages, lifting HDPE round cages, metal cages and other forms. Such as ZL201810291388.3 ZL201810327364.9, etc.

[0004] Disadvantage 1: The current HDPE anti-wave cages are mainly floating HDPE round cages or square cages, which are generally welded on-site by hot-melt welding machines, and their buoyancy is provided by closed HDPE pipes. However, due to the relatively complex manufacturing process and high cost, the number of popularization and application is very small.

[0005] Disadvantage 2: There are many typhoons in the East my country Sea and South China Sea every year. If floating anti-wind and wave cages are used in the sea areas where typhoons pass, the cage system will often be damaged, the aquaculture objects will escape or die, and the aquaculture units will suffer significant economic losses. The currently used lifting HDPE circular cages use air inlet and exhaust valves and water inlet and outlet valves installed on the floating pipes, and the cages float or sink by inlet (exhaust) air and discharge (inlet) water in the floating pipes. These cages have complex structures and poor reliability; it is difficult to meet the safety requirements of aquaculture cages under severe sea conditions.

[0006] Disadvantage 3: Metal cages have high production costs and short service life. Even with the best anti-corrosion technology, the service life of a cage in seawater is generally no more than 10 years.

[0007] Disadvantage 4: Existing floating cages generally use multiple anchor points to fix the cage position. When encountering strong winds and waves, it is easy to cause anchor dragging or anchor rope breakage accidents, causing damage to the cage.

[0008] Disadvantage 5: The existing cage installation generally involves installing the nets on site and fixing multiple anchor points. The operation in the wind and waves at sea is highly dangerous, time-consuming and expensive.

[0012] The purpose of this case is to provide a low-cost, long-life, wind and wave resistant, automatic feeding aquaculture cage to meet the demand for low-cost, long-life, wind and wave resistant, automatic feeding aquaculture cages in deep waters of 20-180m and in waters near offshore islands and reefs.

[0016] Hint Figure 3 ----Schematic diagram of feeding bin and wind turbine

[0017] Reference Figure 1 , Figure 2 , Figure 3 The structure and working principle of a low-cost, long-life, wind and wave resistant, automatic feeding aquaculture cage are further explained.

[0018] It consists of an automatic feeding bin and a wind turbine 1, a net pipe floating frame 2, an inlet / exhaust / water valve 3 inside the net pipe floating frame 2, an inner mesh sheet 4, an outer mesh sheet 5, an integral anchor 6 with an internal inlet / exhaust / water valve 7, a net / anchor rope 8 passing through a fixing ring 10 on the net pipe floating frame 2 and connected with the fixing ring of the integral anchor 6, an anchor rope fixing sheet 9 on the inner / outer mesh sheets 4 / 5, a counterweight rod / body 11 under the inner mesh sheet 4 / outer mesh sheet 5, a suction bucket 12 under the integral anchor 6, etc.

[0019] The main materials of the net pipe buoy 2, the integral anchor 6 and the suction bucket 12 are cement reinforced concrete, and the main structure thereof is a hollow core structure.

[0020] The automatic feeding bin and wind turbine 1 are of closed structure, and include 1-a feeding bin, 1-b gas tank, 1-c battery, 1-d air pump and gasoline engine, 1-e electric control\gas control\remote system box, 1-f feeding pipe, 1-h self-locking ventilation pipe, 1-k wind turbine, 1-m fixing rope and antenna and other mechanisms.

[0021] Its structure is:

[0022] The automatic feeding bin and the wind turbine 1 are installed on the net pipe floating frame 2. The air chamber of the net pipe floating frame 2 has an inlet / exhaust / water valve 3. The inner mesh 4, the outer mesh 5 and the counterweight rod / body 11 are between the net pipe floating frame 2 and the integral anchor 6. The integral anchor 6 has an inlet / exhaust / water valve 7.

[0023] The net / anchor rope 8 passes through the fixing ring 10 on the net pipe buoy 2 and the fixing plate 9 on the inner 4 / / 5 outer net sheets and is connected to the fixing ring of the integral anchor 6, connecting the inner net sheet 4 / outer net sheet 5 and the counterweight rod / body, the integral anchor 6 and the net pipe buoy 2 as one; a suction bucket 12 is provided under the integral anchor 6 so that the integral anchor 6 and the suction bucket 12 can be better inserted into the seabed and fixed.

[0024] The counterweight rod / body 11 connected under the inner mesh 4 / outer mesh 5 is fixed to both sides of the integral anchor 6 after the inner 4 / 5 outer mesh and the counterweight rod / body 11 sink to the seabed with the integral anchor 6 to form a net cage and fix it; the different depths of the net ropes in the net / anchor rope 8 can be adjusted to form net cages of different depths. Multiple groups of nets / anchor ropes 8 are connected to the fixing rings of the integral anchor 6 through the fixing rings 10 on the net pipe buoy 2 and fixed at multiple points.

[0025] The automatic feeding bin and wind turbine 1 are of closed structure, and include 1-a feeding bin, 1-b gas tank, 1-c battery, 1-d air pump and gasoline engine, 1-e electric control\gas control\remote system box, 1-f feeding pipe, 1-h self-locking ventilation pipe, 1-k wind turbine, 1-m fixing rope and antenna and other mechanisms.

[0026] Low-cost, long-life technology:

[0027] The material of the net pipe buoy 2, the integral anchor 6 and the suction bucket 12 is high-strength reinforced cement concrete. After simple anti-corrosion treatment, it has good corrosion resistance and a service life of 60-80 years.

[0028] The inner mesh 4 / outer mesh 5 is made of weather-resistant material and generally has a life span of about 6-8 years, that is, it is replaced once. When replacing, just lift the net rope in the net / anchor rope 8 and replace it with a new inner mesh 4 / outer mesh 5 and a counterweight rod / body 11 to form a new net box.

[0029] This structure and reinforced cement material can reuse the net pipe float 2, the integral anchor 6 and the suction bucket 12 many times, greatly reducing the production, reset, use and maintenance costs of the net cage.

[0030] Wind and wave resistance technology:

[0031] Sea waves have a huge destructive effect on aquaculture cages. The wind and wave resistance principle of this case:

[0032] 1. The network management buoy 2 and the integral anchor 6 are corrosion-resistant, high-strength reinforced concrete reinforced structures. The integral anchor 6 and the suction bucket 12 are inserted into the seabed, and the anchoring has greater adhesion to the seabed.

[0033] 2. When there are strong winds and waves at sea, the water inlet and outlet / air valve 3 of the grid float 2 is opened through the automatic / electrical / pneumatic control and remote system 1-e, and seawater is poured into the air cavity of the grid float 2, so that the grid float 2 sinks to the seawater slow flow layer about 5-8 meters below the sea surface to protect the aquaculture box.

[0034] When the wind and waves are small, the automatic / electrically controlled / pneumatically controlled / remote system 1-e starts the air pump 1-c and the gasoline engine, and inflates the air cavity in the net pipe float 2 through the water inlet and outlet / air valve 3 in the net pipe frame 2 to discharge the seawater in the air cavity, so that the net pipe float 2 rises to the sea surface. This structure ensures the long-term reliability of the sinking and floating adjustment of the net pipe float 2, and has a simple structure and strong applicability.

[0035] 3. The net / anchor rope 8 is made of high-strength carbon fiber material and is between 20-150 meters or fixed depth according to requirements to adapt to different water depths and enhance the ability to resist wind and waves.

[0036] Automatic feeding technology:

[0037] The automatic feeding bin and wind turbine 1 are of closed structure, and include 1-a feeding bin, 1-b gas tank, 1-c air pump and gasoline engine, 1-e electric control, gas control, remote system, 1-d battery, 1-f feeding pipe, 1-h self-locking ventilation pipe, 1-k wind turbine, 1-m fixing rope and antenna and other mechanisms.

[0038] During automatic feeding, the 1-e electric control\pneumatic control\remote system controls the 1-c air pump and the gasoline engine to start inflation, and feeds the bait in the storage bin to the breeding cage through the 1-f feeding pipe to feed the fish.

[0039] The 1-e electric control\pneumatic control\remote control system can also collect and send wind and wave parameters, fish growth parameters, etc. to the land control center, reducing the workload and risks of manual feeding.

[0040] The overall rapid deployment technology of aquaculture boxes at sea:

[0041] During factory production, the integral anchor 6 and the suction bucket 12 are hoisted on the platform, and the inner mesh 4 / outer mesh 5 and the counterweight rod / body 11, and the net / anchor rope 8 assembly are installed and fixed on the fixing ring of the integral anchor 6;

[0042] Then, the net management float 2 is hoisted on the inner net sheet 4 / outer net sheet 5 and the net / anchor rope 8 assembly, and connected and fixed with the net / anchor rope 8 and the fixing ring 10 of the net management float 2;

[0043] Finally, the automatic feeding bin and the wind turbine 1 are installed on the network management float 2.

[0044] Fix the net management float 2, the integral anchor 6 and the suction bucket 12 to form a towable float; tow it into the sea to the designated waters and release the fixation; open the water inlet and outlet / air valve on the integral anchor 6, put in seawater, the integral anchor 6 and the suction bucket 12 sink to the seabed, and the stacked inner mesh 4 / outer mesh 5 assembly and the counterweight rod / body 11 are simultaneously unfolded to form a net cage. The offshore deployment of a net cage is completed.

[0045] After the integral anchor 6 and the suction bucket 12 are inserted into the seabed as the bottom, the different lengths of the net ropes in the net / anchor rope 8 can be adjusted to adjust the water depth of the inner mesh 4 / outer mesh 5 and the counterweight rod / body 11 to form cages of different depths.

[0046] Application examples:

[0047] The net pipe float 2, the integral anchor 6 and the suction bucket 12 are made of cement sewer pipes with a side length of 1.2 meters and a width of 0.8 meters and corresponding mesh pieces. After many experiments and improvements, the principle experimental cage was tested many times in a small fishing port and a water area with a depth of about 6 meters, and the design effect was achieved.

[0048] Advantages of this technology:

[0049] 1. The net management buoy 2, the integral anchor 6 and the suction bucket 12 use high-strength reinforced concrete as the main material. Such structural parts can be soaked in seawater for a long time and have a service life of 60-80 years. The above materials and structures greatly extend the service life of the net management buoy 2, the integral anchor 6 and the suction bucket 12, and reduce the production, reset, use and maintenance costs.

[0050] 2. Through the design of the net / anchor rope 8, the inner mesh 4 / outer mesh 5 and the counterweight rod / body 11 are made into a replaceable structure. When the mesh reaches the end of its service life, a new inner mesh 4 / outer mesh 5 and the counterweight rod / body 11 can be replaced to form a new net box. This structure greatly reduces the reset, maintenance and use costs of the net box.

[0051] 3. Net management buoy 2, integral anchor 6 and suction bucket 12. With this structure, after seawater is poured into the integral anchor 6 to increase its weight, the suction bucket 12 is inserted into the seabed, making the adhesion of the integral anchor 6 and the suction bucket greater, thereby improving the net cage's ability to resist wind and waves.

[0052] 4. The structure of the automatic feeding bin and the wind turbine 1 can realize remote, automatic or programmed control. When the wind and waves are strong, the net management float 2 can be automatically lowered to 5-8 meters below the sea surface, greatly improving the wind and wave resistance of the aquaculture cage.

[0053] 5. The structure of the automatic feeding bin and the wind turbine 1 can realize remote, automatic or programmed control of the feeding times and quantities, so that the fish in the breeding cages are not affected by wind and waves, and the feeding is normal, and the fish grow fast.

[0054] 6. After the automatic feeding bin and wind turbine 1, mesh management float 2, inner mesh 4 / outer mesh 5 assembly and integral anchor 6 are installed and fixed on the onshore platform, they are directly towed to the designated sea area, untied and fixed, seawater is poured into the integral anchor 6, and the integral anchor 6 and suction bucket 12 are inserted into the seabed; at the same time, the inner mesh 4 / outer mesh 5 assembly is also opened and installed on the side of the integral anchor 6 with the counterweight rod / body 11 under gravity to form a breeding cage.
