Description

Technical Field

[0001] The invention relates to the technical field of aquaculture cages, in particular to a floating aquatic product aquaculture cage. Background Art

[0002] Cage aquaculture originated in Cambodia and other Southeast Asian countries in the late 19th century, and later spread to all parts of the world. In the 1970s, my country began cage aquaculture. Due to the characteristics of low investment, high yield, mobility and quick results, cage aquaculture has flourished in lakes and reservoirs across the country in just a few decades.

[0003] According to a Chinese patent with application publication number CN109042423A, a fish farming cage is disclosed, which can capture fish of different sizes;

[0004] In the process of using the above-mentioned aquaculture cages, we found that in the process of feeding feed to aquatic products, the feed fed into the breeding box is easily atomized in the water body and easily flows with the water flow. The feed at the edge of the breeding box is easily carried out of the breeding box through the net flowers by the water flow, resulting in the feed cannot be eaten by the aquatic products, causing a certain amount of waste. In addition, the atomization of feed in the water body is also likely to cause water pollution. For this reason, we propose a floating aquaculture cage to solve the above-mentioned technical problems. Summary of the invention

The air inflated into the upper air-guiding square tube enters the multiple expansion tubes through the multiple upper air distribution ports, and then enters the interior of the lower air-guiding square tube through the lower air distribution ports. Since the interior of the expansion tube is continuously inflated, the expansion tube is continuously expanded until the outer walls of two adjacent expansion tubes collide with each other. At this time, the multiple expansion tubes are surrounded by a closed structure to ensure that the water flow outside the breeding box will not enter the interior of the breeding box laterally. After that, the breeder can scatter the feed into the breeding box to ensure that the heavy feed put into the breeding box will not be washed away by the flowing water after atomization, so that it can be eaten by aquatic products as much as possible, avoiding feed waste, and also avoiding the feed atomization into the water that may cause water pollution in the breeding waters.

[0038] 2. In the present invention, by opening the solenoid valve, the expansion tube in the expanded state, under the action of its own resilience, blows the air inside it through the upper air guide square tube, the air hole, the air guide tube, the solenoid valve, the air supply tube and the guide hole into the interior of the fixing buckle, and then sprays it toward the diffuse reflection plate through multiple injection ports. Since the diffuse reflection plate is arranged in an irregular wave fold shape, the air sprayed onto the surface of the diffuse reflection plate is immediately diffusely reflected to the periphery, thereby disturbing the water flow, and blowing the external water flow into the interior of the breeding box through the gap between two adjacent expansion tubes, so that the breeding box forms a water flow effect, thereby discharging a small amount of feed remaining in the breeding box and part of the feces of aquatic products out of the breeding box through the action of water flow, so that after feeding, the water body inside the breeding box is restored to a clean state, thereby improving the survival rate of aquatic products.

[0061] Reference Figure 3 to Figure 7 As shown:

[0062] The upper air guide portion 300 includes:

[0063] The upper gas-guiding square tube 301 is fixedly mounted on the top of the horizontal frame 101 located at the upper layer through a bracket. A plurality of upper gas distribution ports 302 distributed at equal distances are provided at the bottom of the upper gas-guiding square tube 301. The upper gas distribution ports 302 are communicated with the inner cavity of the upper gas-guiding square tube 301. The upper portion of the outer wall of the expansion tube 203 is fixedly connected with the inner wall of the upper gas distribution port 302.

[0064] The upper air guide portion 300 further includes:

[0065] The boost pipe 303 is fixedly installed on the front of the upper air-guiding square tube 301, and the interior of the boost pipe 303 is connected to the interior of the upper air-guiding square tube 301. A plurality of equidistantly distributed air holes 304 are provided on the top of the upper air-guiding square tube 301 away from the boost pipe 303, and the air holes 304 correspond to the position of the drainage part 500.

[0066] The lower air guide portion 400 includes:

[0067] The lower air guiding square tube 401 is fixedly installed at the bottom of the horizontal frame 101 located at the lower layer through a bracket. A plurality of lower air distribution ports 402 distributed at equal distances are opened on the top of the lower air guiding square tube 401. The lower air distribution ports 402 are connected to the inner cavity of the lower air guiding square tube 401, and the lower part of the outer wall of the expansion tube 203 is fixedly connected to the inner wall of the lower air distribution port 402.

[0068] Before the feed needs to be put in, the air pipe of the external air pump is connected to the booster pipe 303, and the interior of the upper air-guiding square tube 301 is inflated. The air filled into the upper air-guiding square tube 301 enters the multiple expansion tubes 203 through the multiple upper air distribution ports 302, and then enters the interior of the lower air-guiding square tube 401 through the lower air distribution ports 402. Since the interior of the expansion tube 203 is continuously inflated, the expansion tube 203 is continuously expanded until the outer walls of two adjacent expansion tubes 203 collide with each other. At this time, the multiple expansion tubes 203 are surrounded by a closed structure on all sides to ensure that the water flow outside the breeding box will not enter the interior of the breeding box laterally. After that, the breeder can scatter the feed into the breeding box to ensure that the feed put into the breeding box will not be washed away by the flowing water after being atomized, so that it can be eaten by aquatic products as much as possible, avoiding feed waste, and also preventing the feed from being atomized into the water and causing water pollution in the breeding waters.

[0069] Reference Figures 5 to 8 As shown:

[0070] The drainage portion 500 includes:

[0071] Drainage tubes 501, the number of drainage tubes 501 matches the number of air holes 304, and a guide hole 508 is opened at the top of the drainage tube 501;

[0072] The air supply pipe 503 is fixedly installed on the top of the guide hole 508, the end of the air supply pipe 503 is fixedly installed with a solenoid valve 504, the input end of the solenoid valve 504 is fixedly installed with an air guide pipe 505, and the input end of the air guide pipe 505 is fixedly connected to the opening of the air hole 304;

[0073] Injection port 502: A plurality of injection ports 502 are provided on a side of the drainage pipe 501 away from the upper air guiding square pipe 301 and are evenly spaced from top to bottom;

[0074] Fixed bridge 506 , the top of the upper gas guiding square tube 301 and the bottom of the lower gas guiding square tube 401 are fixedly installed with fixed bridge 506 , and the drainage tube 501 is fixedly installed between the upper and lower fixed bridges 506 .

[0075] The reflecting part 600 includes:

[0076] A diffuse reflection plate 601 is fixedly installed between the upper and lower fixed bridge frames 506 , the position of the diffuse reflection plate 601 corresponds to the position of the injection port 502 , and the number of the diffuse reflection plates 601 matches the number of the drainage tubes 501 , and the diffuse reflection plate 601 is arranged in an irregular wavy fold shape.

[0077] After the aquatic products have been eating for a while, the solenoid valve 504 is opened. The expansion tube 203 in the inflated state, under the action of its own resilience, blows the air inside it into the interior of the fixing buckle 201 through the upper air guide square tube 301, the air hole 304, the air guide tube 505, the solenoid valve 504, the air supply tube 503 and the guide hole 508, and then sprays it toward the diffuse reflection plate 601 through multiple injection ports 502. Since the diffuse reflection plate 601 is arranged in an irregular wave fold shape, the air sprayed onto the surface of the diffuse reflection plate 601 is immediately diffusely reflected to the periphery, thereby disturbing the water flow, and blowing the external water flow into the interior of the breeding box through the gap between two adjacent expansion tubes 203, so that the breeding box forms a water flow effect, thereby discharging a small amount of feed remaining in the breeding box and part of the feces of the aquatic products through the water flow, so that after feeding, the water body inside the breeding box is restored to a clean state, thereby improving the survival rate of the aquatic products.

[0078] Reference Figure 4 As shown:

[0079] A plurality of belts 700 equidistantly distributed vertically are provided between the upper gas-guiding square tube 301 and the lower gas-guiding square tube 401 . The belts 700 are fixedly mounted on the periphery of the plurality of expansion tubes 203 . The belts 700 are made of linen.

[0080] By providing the waist belt 700 , multiple expansion tubes 203 are connected laterally, thereby preventing the expansion tubes 203 from lateral bending and improving the strength of the expansion tubes 203 .

[0081] Reference Figure 3 As shown:

[0082] A bottom dense mesh 800 is fixedly installed inside a horizontal frame 101 located at the lower layer.

[0083] By setting the bottom dense net 800, on the one hand, the bottom of the breeding box is sealed to prevent aquatic products from escaping from the bottom of the breeding box. On the other hand, the bottom dense net 800 seals the bottom of the breeding box so that the feed will not sink to the bottom of the water due to the interception effect of the bottom dense net 800, thereby avoiding feed waste.

[0084] Reference Figure 1 , Figure 2 As shown:

[0085] The support portion 900 includes:

[0086] There are cantilever beams 901 fixedly installed on the left and right sides of the transverse frame 101 located on the upper layer. There are multiple cantilever beams 901, and the multiple cantilever beams 901 are equally divided on the left and right sides of the transverse frame 101. Floating boxes 902 are provided on the left and right sides of the transverse frame 101. The floating boxes 902 are fixedly installed on the bottom of the cantilever beams 901 by hoops. There are net bridges 903 on the left and right sides of the transverse frame 101. The net bridges 903 are fixedly installed on the top of the cantilever beams 901.

[0087] The pontoon 902 is connected to the frame part 100 by the cantilever beam 901, and the buoyancy provided by the left and right pontoons 902 can make the breeding box float firmly on the water surface to prevent the breeding box from sinking. At the same time, the net bridge 903 can be interconnected with the net bridge 903 on the adjacent breeding box to form a corridor bridge, which is convenient for the breeder to feed.

[0088] In this scheme, a floating aquatic product aquaculture cage is placed in the aquaculture waters when it is working. The buoyancy provided by the two floating boxes 902 on the left and right makes the aquaculture cage float stably on the water surface. The horizontal frame 101 and the vertical beam 102 are arranged to provide a support effect for the multiple expansion tubes 203. Then, a mesh cage structure is formed by the multiple equally spaced expansion tubes 203 and the bottom dense mesh 800 at the bottom, which can ensure that the aquatic products will not escape. In addition, the distance between the expansion tubes 203 of the aquaculture cage can be adjusted according to the size of the aquatic products to be cultured, so that it is suitable for the aquaculture of different sizes of aquatic products.

[0089] Before feeding, the air pipe of the external air pump is connected to the booster pipe 303, and the interior of the upper air-guiding square tube 301 is inflated. The air inflated into the upper air-guiding square tube 301 enters the multiple expansion tubes 203 through the multiple upper air distribution ports 302, and then enters the interior of the lower air-guiding square tube 401 through the lower air distribution ports 402. Since the interior of the expansion tube 203 is continuously inflated, the expansion tube 203 is continuously expanded until the outer walls of two adjacent expansion tubes 203 collide with each other. At this time, the multiple expansion tubes 203 are surrounded by a closed structure to ensure that the water flow outside the breeding box will not enter the interior of the breeding box laterally. After that, the breeder can scatter the feed into the breeding box to ensure that the feed put into the breeding box will not be washed away by the flowing water after being atomized, so that it can be eaten by aquatic products as much as possible, avoiding feed waste, and also avoiding the feed atomized into the water to cause water pollution in the breeding waters;

[0090] After the aquatic products have been eating for a while, the solenoid valve 504 is opened. The expansion tube 203 in the inflated state, under the action of its own resilience, blows the air inside it into the interior of the fixing buckle 201 through the upper air guide square tube 301, the air hole 304, the air guide tube 505, the solenoid valve 504, the air supply tube 503 and the guide hole 508, and then sprays it toward the diffuse reflection plate 601 through multiple injection ports 502. Since the diffuse reflection plate 601 is arranged in an irregular wave fold shape, the air sprayed onto the surface of the diffuse reflection plate 601 is immediately diffusely reflected to the periphery, thereby disturbing the water flow, and blowing the external water flow into the interior of the breeding box through the gap between two adjacent expansion tubes 203, so that the breeding box forms a water flow effect, thereby discharging a small amount of feed remaining in the breeding box and part of the feces of the aquatic products through the water flow, so that after feeding, the water body inside the breeding box is restored to a clean state, thereby improving the survival rate of the aquatic products.
