DETAILED DESCRIPTION
[0024] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.
[0025] This embodiment provides an aquaculture system, which is mainly used for canvas tube or similar aquaculture, wherein the aquatic products may be freshwater fish, ornamental fish or other aquatic products suitable for breeding.
[0026] refer to Figure 1 As shown, the aquaculture system provided in this embodiment mainly includes a culture pond 1, and the culture pond preferably adopts a canvas tube culture pond structure, that is, the outside of the culture pond can adopt a metal barrel body and the inside is covered with canvas. The culture pond 1 preferably adopts a circular barrel structure, and the bottom of the culture pond 1 is set to a conical structure as shown in the figure to facilitate sewage collection.
[0027] In this embodiment, a barrel 2 is provided at the center of the culture pond 1. In a specific implementation provided in this embodiment, the barrel 2 is made of a metal pipe structure, and its support is installed at the center of the culture pond 1. The barrel 2 is mainly used to filter the dirt (such as fish feces, organic matter, etc.) in the water during the water circulation process. In a preferred solution provided in this embodiment, the bottom of the barrel 2 is supported on a bracket 8, and the distance between the bottom of the barrel 2 and the conical bottom of the culture pond 1 is 10-20CM to ensure the water circulation process. The bracket 8 is mainly used to support the barrel 2, which can be used Figure 2 The support structure shown may also adopt other support structures. Figure 2 In the structure shown, the bracket 8 is composed of a plurality of support rods, which are crossed to form a grate plate structure, and the barrel body 2 is fixed on the support rods.
[0028] A circulation pump 3 needs to be set inside the barrel body 2, and the circulation pump 3 is connected to the water outlet pipe 5 located at the top of the barrel body 2 through the vertical pipe 4. In this way, when the circulation pump 3 is turned on, the water in the breeding pond 1 enters through the bottom of the barrel body 2, and is sprayed into the breeding pond 1 from the water outlet of the water outlet pipe 5 under the action of the circulation pump 3, thereby realizing water circulation in the breeding pond 1.
[0029] A partition net 9 is arranged at the lower part of the barrel body 2, and the mesh size of the partition net 9 is: the fish in the fish pond can be isolated below the partition net 9 to prevent the fish from entering the barrel body 2. Above the partition net 9 in the barrel body 2 is the filter chamber 11. As mentioned above, the water flow can enter from the bottom of the barrel body 2 through the circulating pump 3, and finally spray out from the outlet pipe 5 after passing through the filter chamber 11. In this process, when the water flow passes through the filter chamber 11, the fish feces and organic matter mixed in the water flow can be filtered and retained in the filter chamber 11, thereby ensuring the cleanliness of the water body in the breeding pond 1. The filter material arranged in the filter chamber 11 can be a brush 10 or a biochemical ball. When cultivating ornamental fish, it is preferred to place the brush 10 and the biochemical ball 12 at the same time to ensure the filtering effect. And the biochemical ball 12, as a kind of ornamental fish biochemical filter material, also has an oxygenation effect.
[0030] As described above, in the above structure of the present embodiment, during the water circulation process, part of the fish feces and organic matter will be retained in the filter bin 11. At the same time, in the utility model, the bottom of the culture pond 1 is conical, and the water will enter the barrel body 2 through the middle of the cone during the circulation process. In this process, most of the dirt will gather and be retained at the conical bottom of the culture pond 1. In this way, an internal sewage outlet 13 is formed at the conical bottom, and the internal sewage outlet 13 is connected to the external sewage outlet 15 located outside the culture pond 1 through a sewage pipe 14. A plug 16 is provided at the external sewage outlet 15. When sewage needs to be discharged, the plug 16 is opened. Under the action of the water pressure inside the culture pond 1, the water flows through the internal sewage outlet 13, the sewage pipe 14, and the external sewage outlet 15. At this time, the dirt gathered at the internal sewage outlet 13 is taken out to achieve sewage discharge. The sewage pipe 14 can also be used as a drain pipe.
[0031] As described above, in this embodiment, through the design of the barrel body 2, when the water circulates, some dirt will gather in the filter bin 11, which needs to be cleaned regularly. Therefore, in this application, a backwash pump 6 is provided in the breeding pond 1, and the backwash pump 6 is located outside the barrel body 2. The backwash pump 6 is connected to the backwash pipe 7, and the water outlet of the backwash pipe 7 is located in the upper part of the barrel body 2. Through the above structure, when changing water or discharging sewage, the circulation pump 3 is turned off, and the backwash pump 6 is turned on. The backwash pump 6 allows the water to flow downward from the upper part of the barrel body 2 through the backwash pipe 7, and the water flow impacts the filter bin 11 in the barrel body 2. The dirt in the filter bin 11 is discharged through the sewage outlet 13 along with the water flow during sewage discharge or water change, thereby realizing the automatic cleaning of the filter bin 11.
[0032] refer to Figure 1 as well as Figure 3As shown, in this embodiment, the top position of the barrel body 2 is higher than the breeding pool 1, the water outlet pipe 5 is located at the top of the barrel body 2, the upper part of the breeding pool 1, the two ends of the water outlet pipe 5 are mounted on the barrel body 2, and both ends are provided with water outlets. During the circulation process, the water flow will contact the external air, and then bring the oxygen in the air into the breeding pool 1 to achieve oxygenation. In a preferred solution provided in this embodiment, as Figure 3 As shown, a 45-degree elbow 17 is provided at the water outlet at both ends of the outlet pipe 5, and the openings of the two elbows 17 face opposite directions. Thus, through the design of the elbow 17, when the water flows out from the elbow 17, it can generate an inclined impact force on the water flow in the breeding pond 1. The elbows 17 on both sides work together, so that the water flow in the breeding pond 1 can generate a certain rotation under the action of thrust, thereby improving the effect of fish feces gathering to the bottom of the breeding pond 1.
