Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture engineering, in particular to a lifting fishing-light integrated aquaculture platform that uses clean energy photovoltaic as the power source to drive the aquaculture cage to complete water layer transformation and automatic cleaning. Background Art

[0002] Aquatic products are an important source for people to supplement high-quality protein. As one of the three major animal foods consumed by people, they have important strategic value for ensuring food security and balancing people's nutritional diet structure. Currently, the main aquaculture methods for oysters include raft hanging cages, raft hanging ropes and other aquaculture methods. In the above traditional aquaculture methods, there are large individual differences in oysters, and each oyster monomer adheres to each other. A large amount of labor and time are required for sorting after harvesting. Especially in the process of raft cage aquaculture, the cages are immersed and suspended in seawater for a long time, and are easily attached by fouling organisms such as algae, barnacles, and ascidians. After attachment, the weight of the aquaculture cage itself will increase, which will reduce the fatigue life of aquaculture facilities such as the cage net and floating rope. At the same time, the large-area attachment of fouling organisms will reduce the water circulation in the cage, which will have an adverse impact on the growth of oysters. For fouling organisms, physical decontamination is regularly carried out during aquaculture at present, and physical decontamination will, to a certain extent, bring greater losses of human and material resources and an increase in aquaculture costs. In addition to the above problems, traditional aquaculture methods also have disadvantages such as limited aquaculture space, large demand for manpower, and low work efficiency.

[0047] The cleaning system 3 is used to wash the breeding cage 28 after it is separated from the water surface; the cleaning system 3 includes a water pump 31, a water pipe 32 and a water spraying mechanism 33.

[0048] In this embodiment, the support frame 20 includes an upper pipe body 11, a lower pipe body 12, longitudinal tie rods 13, diagonal tie rods 14, and fixed diagonal tie rods 17. The upper pipe body 11 and the lower pipe body 12 are connected by three longitudinal tie rods 13. In practical applications, the number of longitudinal tie rods 13 can be appropriately increased. Diagonal tie rods 14 are arranged between two adjacent longitudinal tie rods 13.

[0049] In this embodiment, the aquaculture cage 28 is detachably connected to the cross shaft 27. A C-shaped buckle 15 is convexly arranged on a longitudinal surface of the aquaculture cage 28. The aquaculture cage 28 is connected to the cross shaft 27 through the buckle 15, and the buckle 15 is locked and fixed by a bolt 16. The aquaculture cage 28 includes a cage cover 281 and a cage body 282, and the cage cover 281 is used to open and close the cage body 282.

[0050] The bearing platform 1 serves as a place for aquaculture.

A plurality of through holes 6 are evenly arranged circumferentially on the polygonal bearing platform 1, and the number of through holes 6 is the same as the number of sides of the polygonal bearing platform 1, that is, the number of through holes 6 is determined according to the number of sides of the shape of the bearing platform 1. The through holes 6 are close to the edge of the polygonal bearing platform 1, and the plurality of through holes 6 correspond to and are parallel to the plurality of sides of the polygonal bearing platform 1. Of course, only one through hole 6 can also be provided on the bearing platform 1.

[0051] The photovoltaic panel 4 provides energy for the operation of the bearing platform 1. The photovoltaic panel 4 converts solar energy into electrical energy and has the following uses: one is to provide electrical energy for the motor 21 of the cage lifting system 2; the second is to provide electrical energy for the water pump 31 of the cleaning system 3; the third is to provide electrical energy for the operation of other auxiliary facilities such as lighting facilities, water quality monitoring, and video monitoring on the bearing platform 1; the fourth is to store the electrical energy during the low electricity consumption period in the energy storage battery pack 5, and the electrical energy stored in the energy storage battery pack 5 can provide emergency energy for power-consuming devices such as the cage lifting system 2, the cleaning system 3, and auxiliary facilities.

[0052] When the cage lifting system 2 is working, the motor 21 drives the power shaft 22 to rotate, the power sprocket 23 rotates synchronously with the power shaft 22, the power sprocket 23 drives the transmission chain 26 to move, the transmission chain 26 drives the driven sprocket 25 and the driven shaft 24 to rotate synchronously, and the transmission chain 26 also drives the aquaculture cage 28 to alternately leave the water surface, and the aquaculture cage 28 realizes the transformation of different water layers during the rising and falling processes.

[0053] When the cleaning system 3 is working, the water pump 31 pumps seawater into the water spraying mechanism 33, and the seawater is sprayed out through the nozzles on the water spraying mechanism 33. The high-pressure water column sprayed out by the nozzles flushes the aquaculture cage 28 after it leaves the water surface. In this embodiment, two water pumps 31 are provided. Among them, three water spraying mechanisms 33 are connected in series through a water pipe 32 and then connected to one of the water pumps 31, and the other three water spraying mechanisms 33 are connected in series through a water pipe 32 and then connected to the other water pump 31.

[0054] In this embodiment, four aquaculture cages 28 are equidistantly arranged at intervals on each cross axis 27. Of course, only one aquaculture cage 28 can also be arranged on each cross axis 27, and the number of aquaculture cages 28 on each cross axis 27 can be selected according to the actual situation. The aquaculture cage 28 is injection-molded from polypropylene material, and the aquaculture cage 28 is a water-permeable hollow structure to ensure that the aquaculture organisms inside the aquaculture cage 28 are in full contact with the water body. The buckle 15 is integrally processed with the aquaculture cage 28. As Figure 7 shown, the aquaculture cage 28 is a hexagonal prism structure, the aquaculture cage 28 has an open side cover, and the cage cover 281 and the cage body 282 are opened and closed through a lock.

[0055] As another implementation manner of this embodiment, the aquaculture platform of this embodiment can be grouped and used according to the aquaculture requirements and the characteristics of the aquaculture sea area environment, and the number of groups can be flexibly adjusted. As Figure 8 shown, in the figure, three hexagonal structure bearing platforms 1 are grouped and arranged, and the bearing platforms 1 are connected through the connecting chain 10 passing through the reserved mooring holes 8; that is, three aquaculture platforms are grouped to realize the grouping between aquaculture platforms. Of course, the aquaculture platforms can also be arranged in an array.

[0056] In actual application, in addition to grouping between aquaculture platforms, the aquaculture platform can also be grouped with other aquaculture facilities. The aquaculture facilities can be aquaculture cages 19. As Figure 9 shown, the aquaculture platform of this embodiment is grouped with the aquaculture cage 19. The aquaculture cage 19 has the same shape as the hexagonal structure bearing platform 1. A hexagonal structure bearing platform 1 is arranged at each side of the hexagonal structure aquaculture cage 19, and the aquaculture cage 19 and the bearing platform 1 are connected through the connecting chain 10 passing through the reserved mooring holes 8. The hexagonal structure aquaculture cage 19 and six hexagonal structure bearing platforms 1 together form a honeycomb structure, similar to the stress structure of a honeycomb in nature. The combination of the hexagonal structure bearing platforms 1 has better stability and is more resistant to the impact of wind and waves during grouped aquaculture production. In actual application, the bearing platform 1 can be combined and used according to the aquaculture sea area conditions and aquaculture purposes, and multiple bearing platforms 1 can be arbitrarily combined according to the use requirements.

[0057] In this embodiment, the aquaculture platform is set up in a bay with relatively small wind and waves or in the offshore area with a water depth within 25 m for aquaculture activities. This embodiment of the aquaculture platform can be applied to the traditional offshore aquaculture areas of economic organisms such as oysters and sea cucumbers, and has a wide range of applications.

[0058] A cultivation method for a lifting type fishery-light integrated aquaculture platform:

[0059] The aquaculture platform is deployed in an area with relatively small wind and waves, sufficient sunlight, a water depth of 5 m to 25 m, an annual surface water temperature change range of 0°C to 30°C, no ice-freezing period, and a salinity change range of 25 to 33. It can be of mud bottom, mud-sand bottom or sand-mud bottom. The aquaculture platforms can be used in groups, and the cultivation method for each aquaculture platform is the same.

[0060] The aquaculture platform is applied to the entire growth cycle of oyster cultivation, and can achieve multiple uses compared with the traditional cultivation method. Taking the cultivation of single-body triploid oysters as an example, the cultivation activities using the aquaculture platform are divided into two periods:

[0061] (1) Cultivation period: Put small-sized oyster seedlings less than 3 cm into the aquaculture cage 28. The mesh size of the aquaculture cage 28 is 2 cm * 2 cm. To prevent the seedlings from leaking out, a sieve silk net with the same shape as the aquaculture cage 28 needs to be sleeved inside the aquaculture cage 28 at this time. The sieve silk net is made of polyethylene with a mesh number of 10 meshes. 150 - 200 small-sized oyster seedlings are put into each aquaculture cage 28. The small-sized oyster seedlings are cultivated in the aquaculture cage 28 for 25 days. Of course, it can also be 26 days, 27 days, 28 days, 29 days or 30 days according to the actual situation. When the small-sized oyster seedlings grow to a size of 4.5 - 5.5 cm, they should be sorted in time. The seedlings with a size less than 5 cm are continued to be put into the aquaculture cage 28 sleeved with the sieve silk net for cultivation. The seedlings with a size of 5 cm and above are put into the aquaculture cage 28 without the sieve silk net, and the input amount accounts for about 1 / 5 - 1 / 4 of the volume of the aquaculture cage 28. After the seedlings with a size of 5 cm and above are cultivated in the aquaculture cage 28 for 40 days, of course, it can also be 35 days, 38 days, 43 days or 45 days according to the actual situation, and the seedlings are sorted and repackaged again. Then, in the subsequent cultivation process, whenever the space occupied by the seedlings growth reaches 1 / 2 - 2 / 3 of the volume of the aquaculture cage 28, they should be repackaged in time. A total of 4 or 5 times of seedling sorting and repackaging are carried out for the seedlings during the entire cultivation period. When the cage lifting system 2 works during the cultivation period, the lifting speed of the aquaculture cage 28 is set according to factors such as weather, temperature, and seedling size. During the cultivation period, the lifting speed of the aquaculture cage 28 should be relatively slow, and the rotational speed of the driving sprocket 23 is 30 revolutions per minute. Of course, according to the actual situation, it can also be 10 revolutions per minute or 20 revolutions per minute.

[0062] (2) Shaping period: The shaping period starts 60 days before harvest. During the shaping period, the oysters in each cultivation cage 28 occupy 1 / 2 to 2 / 3 of the volume of the cultivation cage 28, leaving enough space for the oysters to rotate and shape inside the cultivation cage 28. At the same time, when the cage lifting system 2 is working during the shaping period, the lifting speed of the cultivation cage 28 is determined by factors such as weather, temperature, and the growth state of the oysters. The lifting speed of the cultivation cage 28 is appropriately increased, and the rotation speed of the power sprocket 23 is 60 revolutions per minute. Of course, according to the actual situation, it can also be 70 revolutions per minute or 80 revolutions per minute. When the oysters reach the market standard, the cultivation cage 28 can be lifted layer by layer for cage-by-cage harvesting.

[0063] The present utility model uses clean energy photovoltaic as the power source of the cultivation platform, and uses the cage lifting system to cyclically lift and lower each cultivation cage according to a specific cultivation cycle, so that the oysters in each cultivation cage can fully absorb the nutrients in each water layer. When the cultivation cage is lifted to the highest point, the cultivation cage will be washed by the cleaning system to reduce the attachment of fouling organisms on the surface of the cultivation cage. At the same time, the cultivation cage will be separated from the water surface and exposed to air and sunlight. Sun exposure will, to a certain extent, sterilize the cultivation cage, and at the same time, it has a killing effect on fouling organisms such as algae, polydora, and ascidians attached to the surface of the cultivation cage. The oysters in the cultivation cage will be exposed to sunlight and air for a certain period of time, and a certain period of dry exposure will improve the nutritional quality and flavor characteristics of the oysters. During the process of the cultivation cage rising and falling, the oysters will roll fully in the cage, constantly grinding out a high-quality shell shape. High-quality oysters with good shell shape and unique flavor are more likely to be favored by the market, thus greatly improving the cultivation economic benefits. During the entire cultivation process of the cultivation platform, there is no feeding and no pollutant discharge, and the filtering habit of the oysters will purify the water body. The cultivation platform is of great significance for protecting the marine water environment and the marine fishery carbon sink while improving the quality of the cultivated products and reducing the labor intensity of front-line cultivation personnel.
