Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to an underwater automatic feeding device for a flip-type marine ranch. Background Art

[0002] In recent years, with the continuous development and improvement of intensive aquaculture technology, the aquaculture model is changing. The large-scale and intensive aquaculture has brought about feeding difficulties, but there is no good solution. At present, aquaculture is mainly based on artificial feeding, which has problems such as high labor intensity, low efficiency, and difficulty in controlling the amount of bait. Finding a scientific and reasonable feeding technology is crucial to the breeding effect and ecological environment. Feeding machines have become an important part of modern aquaculture machinery because of their advantages such as saving the work intensity of breeding personnel and significant economic benefits. At present, there have been many studies on automated feeding systems at home and abroad, and there are also many applications in pond farming, factory farming and cage farming, but the feeding systems in different breeding environments are also different, and there are different specific forms under the same basic composition model.

[0003] Unlike pond farming, marine farming requires farmers to start from the shore every time they feed, transport the feed over a long distance to the farming platform, and then enter the cage for manual feeding. The workload is much greater than pond farming. If there are multiple platforms that need to be fed, the long transportation distance, large feeding amount and unstable weather factors will not only greatly increase the workload, but also greatly reduce the work efficiency. In addition, unlike pond farming based on land where a large number of farming equipment can be arranged, the farming model based on the ocean platform has very limited space resources, and the energy system, lighting system, monitoring system and various functional cabins on the platform all occupy land area, which compresses the available space for feeding equipment. Therefore, it is crucial for marine farming to realize unmanned and intelligent marine farming with minimal space occupancy and simplify the feeding process.

[0004] Among the structural forms of many marine aquaculture platforms, compared with traditional fixed cages, flip cages are convenient for flipping the bottom net to the upper part for drying and cleaning, which greatly improves the feeding environment and the quality of fish. However, since flip cages need to be flipped regularly, if a feeding device is arranged on the side of the cage to feed the inside, the feed transportation pipeline needs to be recovered every time the cage is flipped, and the pipeline needs to be arranged again after the cage is flipped. This process is too cumbersome. At the same time, a 50*20*10m flip marine ranch for raising large yellow croaker feeds about 3m3 of dry bait a day, about 20m3 in 7 days, which takes up too much work space. Summary of the invention

[0005] The object of the present invention is to provide an underwater automatic feeding device for a flip-type marine ranch, which can reduce the labor intensity of farmers, simplify the operation process of flipping cages and reduce the space occupied by the farming device.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] See also Figures 1 to 9The present invention provides an embodiment: an underwater automatic feeding device for a flip-type marine ranch, comprising a breeding net cage 21, a buoyancy box 1, a breeding platform working deck 2, a stirring structure 3 and a silo structure 4, both sides of the breeding net cage 21 are provided with a rotating shaft 22, and a first through hole is opened on the rotating shaft 22 on one side, the buoyancy box 1 is located on the outside of the breeding net cage 21, the breeding platform working deck 2 is fixed on the top of the buoyancy box 1, and one side of the breeding platform working deck 2 is provided with a heat dissipation structure 6 for dissipating heat from the inside of the buoyancy box 1, The silo structure 4 is fixed to the bottom of the buoyancy box 1, and the stirring structure 3 is arranged in the buoyancy box 1 to stir the feed in the silo structure 4. The buoyancy box 1 is provided with a first small hole 8 at the lower part near the end face of the cage. The inner side of the first small hole 8 is connected to the feed discharge pipe 7 on the silo structure 4, and the outer side of the first small hole 8 is connected to the feed transport pipe 11. One end of the feed transport pipe 11 passes through the first through hole and is located in the breeding cage 21. The working deck 2 of the breeding platform is also provided with a feeding device console 9. The buoyancy box 1 is provided by the breeding platform itself and is airtight. The breeding staff can realize automatic feeding by remotely or closely manipulating the feeding device console 9. The console is equipped with an electronic control integration system and a remote control module. The console can be connected to a mobile phone for remote control of feed feeding, allowing farmers to feed fish offshore. They only need to regularly replenish feed in the silo and board the ship, reducing the number of boardings and the labor intensity of farming. At the same time, farmers can also control feed feeding at close range on the farming platform, and can observe the fish breeding conditions in real time and finely adjust the feeding amount. A fish observation camera can also be set in the breeding net cage 21. The fish observation camera is used to observe the feeding situation of the fish school, which is convenient for the breeders to judge the feeding time and feeding amount. When the feeding device console 9 sends a signal to start feeding, the stirring structure 3 is started to make the feed in the silo evenly distributed, and the silo structure 4 evenly transfers the feed in the silo structure 4 to the feed transportation pipe 11 and sends it to the breeding net cage 21. The feed transportation pipe 11 enters the breeding net cage 21 through the small hole on the rotating shaft 22. When the net cage is turned over, there is no need to recover the feed transportation pipe 11, which is convenient for feeding and reduces the labor intensity of the breeders. At the same time, the feeding work time is long, which will cause the internal temperature of the closed buoyancy box 1 to rise. The feeding device console 9 can start the heat dissipation structure 6 to send external air into the box body and send the internal hot air out of the box body.

The stirrer motor 31 is connected to the second through hole on the working deck 2 of the breeding platform through a stirrer bearing 33. The stirrer motor 31 can drive the stirrer screw 32 to rotate so that the feed in the silo is evenly distributed. The use of screw feeding can ensure that the discharge amount is accurate and uniform, and can prevent the discharge pipeline from being blocked due to excessive storage.

The other end of the heat dissipation air filling pipe 62 passes through the third through hole on the working deck 2 of the breeding platform and is located below the silo structure 4. An internal and external air pressure balance pipe 64 is fixed to the side of the heat dissipation air filling pipe 62. One end of the internal and external air pressure balance pipe 64 is located below the silo structure 4, and the other end passes through the fourth through hole on the working deck 2 of the breeding platform and is located on the outside of the working deck 2 of the breeding platform. The inner side walls of the third through hole and the fourth through hole are both provided with sealing rubber sleeves 20. When the feeding blower 43 works for a long time, the temperature inside the closed buoyancy box 1 will rise. At this time, the heat dissipation blower 61 is started to send external air into the box through the heat dissipation air filling pipe 62, and the internal hot air is then sent out through the internal and external air pressure balance pipe 64. The heat dissipation blower 61 adopts a low-power blower.

The feed blower 43 uses a high-power blower, and the motor of the blower is also connected to the feeding device console 9 and is directly controlled by the feeding device console 9. When the console increases the discharge amount of the feeder 42, the blower power is simultaneously increased to ensure continuous feeding. The feed outlet is connected to the feed transport pipe 11 for blowing out feed.
