[0032] The present application provides a feeding net cage, please refer to Figure 1 The feeding net cage comprises:

[0033] The gas storage float pipe 1 is arranged in a ring shape, and is provided with a gas storage channel 11 and an air inlet channel 12; the gas storage float pipe 1 is used to connect the net cage body, so that the net cage body is located in the surrounding area of the gas storage float pipe 1.

[0034] The storage pipe 2 is arranged in the surrounding area of the gas storage float pipe 1, and is in communication with the gas storage float pipe 1 through the air inlet channel 12; the storage pipe 2 is provided with a discharge channel 21; the storage pipe 2 is used to store the bait to be fed.

[0035] Specifically, the gas storage float pipe 1 is a thick circular pipe surrounding the net cage body, and the net cage body is connected to the gas storage float pipe 1 along the circumference, and the surrounding area of the gas storage float pipe 1 is the upper opening of the net cage body; the gas storage float pipe 1 can be made of high-density polyethylene material; the gas storage channel 11 of the gas storage float pipe 1 is used to connect the shipborne air compressor through the air compressor connecting end 5, so as to store the compressed air provided by the air compressor, so that the gas storage float pipe 1 can float on the water surface by the buoyancy of the compressed air, to form the buoyancy device of the net cage body, and the surface of the gas storage float pipe 1 can be used for personnel walking and working; wherein, the air compressor connecting end 5 can include related devices and corresponding connecting devices connected to the air compressor, which is used to realize the butt joint of the gas storage float pipe 1 and the air compressor.

[0036] The bait storage pipe 2 is pre-stored with bait to be fed, and is located at the upper opening of the net cage body; by means of the air inlet channel 12, the compressed air in the air storage float pipe 1 can provide power for the bait storage pipe 2 to move the bait to be fed, so as to push the bait to be fed in the bait storage pipe 2 to be discharged from the discharge channel 21 into the net cage body for the fish in the net cage body to eat; and by specifically setting the position of the discharge channel 21 on the bait storage pipe 2, precise directional feeding can also be achieved. During the above bait feeding process or after the bait feeding is completed, the air storage channel 11 can continuously provide compressed air for the air storage float pipe 1 to ensure the buoyancy of the air storage float pipe 1.

[0037] It can be seen that the feeding net cage provided in the embodiment transforms the air storage float pipe 1 of the traditional HDPE (high-density polyethylene float pipe) net cage, so that the compressed air in the air storage float pipe 1 can provide power for the bait storage pipe 2 pre-stored with bait to be fed to move and discharge the bait; the feeding net cage has low cost and simple structure, and can realize bait feeding in a convenient way without the need for transporting the bait to the vicinity of the net cage by means of a transport ship and without the need for throwing the bait by workers, so as to reduce the labor pressure, improve the feeding operation efficiency and reduce the feeding operation cost.

[0038] Optionally, referring to Figure 1 , the bait storage pipe 2 is provided with a bait supplement channel 4, and the bait supplement channel 4 is used to connect with the bait air conveying device 6; specifically, the bait supplement channel 4 can be communicated with the marine bait air conveying device 6 through the fifth valve 41, when the bait to be fed in the bait storage pipe 2 needs to be supplemented, the fifth valve 41 can be opened, and the air pressure provided by the bait air conveying device 6 is used to push the external bait into the bait storage pipe 2 through the bait supplement channel 4, so as to complete the convenient supplement of the bait in the bait storage pipe 2.

[0039] Optionally, referring to Figure 1 , the bait storage pipe 2 is provided with an air permeable channel 22, and the air permeable channel 22 is provided with a screen, and the screen is used to block the bait to be fed.

[0040] In the embodiment, when the bait to be fed in the bait storage pipe 2 needs to be supplemented, the mixture of air and the bait to be fed can be directly input into the bait storage pipe 2 through the bait supplement channel 4 by using the bait air conveying device 6, or the mixture of air and the bait to be fed can be input into the bait storage pipe 2 through the air storage float pipe 1 outside; and by setting the air permeable channel 22, when the mixture of air and the bait to be fed completely enters the bait storage pipe 2, the air can be discharged through the air permeable channel 22, and the bait to be fed is deposited and stored near the air permeable channel 22 of the bait storage pipe 2 under the blockage of the screen, so as to realize the rapid supplement of the bait in the bait storage pipe 2; and the screen can also prevent the bait to be fed from splashing at the same time.

[0041] Optionally, referring to Figure 1The gas storage channel 11 is provided with a first valve 111, which is any one of an electromagnetic valve and an electric valve.

[0042] Optionally, referring to Figure 1 The gas inlet channel 12 is provided with a second valve 123, which is any one of an electromagnetic valve and an electric valve.

[0043] Optionally, referring to Figure 1 The discharge channel 21 is provided with a third valve 211, which is any one of an electromagnetic valve and an electric valve.

[0044] Optionally, referring to Figure 1 The gas permeation channel 22 is provided with a fourth valve 221, which is any one of an electromagnetic valve and an electric valve.

[0045] Optionally, referring to Figure 1 The material supplement channel 4 is provided with a fifth valve 41, which is any one of an electromagnetic valve and an electric valve.

[0046] In the traditional feeding operation mode, the feeding time window is limited by sea conditions, and feeding cannot be performed under high sea conditions. The manual feeding method can only meet the needs of small-scale net cage breeding. Based on this problem, the embodiment corresponds to the setting of remotely controllable electromagnetic valves or electric valves at the gas storage channel 11, the gas inlet channel 12, the discharge channel 21, the gas permeation channel 22, and the material supplement channel 4. The staff can control the on-off state of each channel through remote switching to flexibly switch between multiple working modes through different on-off combination forms without the need for on-site operation, thereby completely freeing the hands and improving the degree of equipment mechanization. Under high sea conditions, bait feeding and other operations can still be completed, and the device has good adaptability to net cages of different sizes. In the actual application process, only the sizes of each accessory need to be adjusted according to the size of the net cage, and the feeding time will not be significantly increased due to the increase in the size of the net cage. It can be applied to large-scale cluster type net cages for rapid feeding operation.

[0047] Specifically, the on-off state of the channel corresponding to the feeding net cage in each working mode is as follows:

[0048] When the gas storage operation is performed, the first valve 111 is opened, and the second valve 123, the third valve 211, the fourth valve 221 and the fifth valve 41 are closed, so that the compressed air in the air compressor is filled into the gas storage float pipe 1; when the feeding operation is performed, the first valve 111, the fourth valve 221 and the fifth valve 41 are closed, and the second valve 123 and the third valve 211 are opened, so that the compressed air in the gas storage float pipe 1 enters the storage pipe 2 as power to push the to-be-fed bait in the storage pipe 2 to be discharged from the discharge channel 21 to the net cage body; when the feeding operation is performed, the fourth valve 221 and the fifth valve 41 are opened, and the first valve 111, the second valve 123 and the third valve 211 are closed, so that the mixture of air and to-be-fed bait is input into the storage pipe 2 through the bait air conveying device 6, and the air in the mixture can be discharged through the air permeable channel 22, and the to-be-fed bait in the mixture is deposited and stored near the air permeable channel 22 under the blockage of the screen.

[0049] Optionally, referring to Figure 1 , the storage pipe 2 is arranged in an open ring shape, the air inlet channel 12 comprises a first channel 121 and a second channel 122, and the first channel 121 and the second channel 122 are arranged at intervals along the circumference of the gas storage float pipe 1; one end of the storage pipe 2 is communicated with the gas storage float pipe 1 through the first channel 121, and the other end of the storage pipe 2 is communicated with the gas storage float pipe 1 through the second channel 122.

[0050] In the embodiment, when the storage pipe 2 is arranged in an open ring shape as shown in Figure 1 , the compressed air in the gas storage float pipe 1 can be supplied into the storage pipe 2 from both ends of the storage pipe 2 in clockwise and counterclockwise directions at the same time; compared with the one-way air supply mode, the two-way air supply mode of the embodiment can make the compressed air fill the storage pipe 2 faster, so that the bait feeding efficiency can be improved. Preferably, the first channel 121 and the second channel 122 are arranged on the side of the gas storage float pipe 1 away from the gas storage channel 11, and one second valve 123 is arranged on each of the first channel 121 and the second channel 122.

[0051] Optionally, referring to Figure 1 , the storage pipe 2 is provided with at least two discharge channels 21 and at least one air permeable channel 22; the at least two discharge channels 21 are uniformly distributed along the circumference of the storage pipe 2, and at least one air permeable channel 22 is arranged between the at least two adjacent discharge channels 21.

[0052] In the embodiment, by arranging at least two discharge channels 21, the bait feeding area can be expanded, and the uniformity of bait feeding can be improved. Preferably, a third valve 211 can be arranged on each discharge channel 21. In this way, different discharge channels 21 can be controlled to discharge bait according to actual conditions, so as to realize directional feeding. The staff can change the feeding point and the feeding direction according to the real-time change of the sea current, and can realize uniform feeding of bait in the net cage by means of the sea current.

[0053] By arranging the air passage 22 between two adjacent discharge channels 21, the bait can be preferentially deposited between the two discharge channels 21 during the bait feeding operation, so as to improve the uniformity of bait discharge of the two discharge channels 21 in the subsequent bait feeding operation, and avoid the situation that the bait to be fed is too much at one discharge channel 21 and the bait to be fed is insufficient at the other discharge channel 21. Preferably, the air passage 22 can also be arranged as two or more than two; for example Figure 1 When the discharge channel 21 is arranged as three, the air passage 22 can be correspondingly arranged as two, each air passage 22 is located between two adjacent discharge channels 21, and a fourth valve 221 is arranged on each air passage 22. In this way, by controlling the fourth valve 221 to make different air passages 22 conductive during the bait feeding operation, the bait to be fed in the bait storage pipe 2 can be sequentially deposited and stored in segments.

[0054] Optionally, referring to Figure 1 , the feeding net cage comprises a bait feeding device 3, the bait feeding device 3 is communicated with the discharge channel 21, and the bait feeding device 3 is arranged downwardly inclined.

[0055] Specifically, the bait feeding device 3 can adopt an existing bait feeder. The bait to be fed in the discharge channel 21 can be sprayed in a preset direction by means of a corresponding guide structure. The bait feeding device 3 can be connected with the discharge channel 21 by means of a flange connector. When the bait feeding device 3 is arranged downwardly inclined, the bait to be fed can be efficiently sprayed under the combined action of compressed air and gravity by means of gravity, so as to improve the bait feeding efficiency.

[0056] Optionally, referring to Figure 2 , the bait storage pipe 2 is arranged at equal intervals with the gas storage float pipe 1, and the bait storage pipe 2 is connected to the gas storage float pipe 1 by means of a fixed support 7.

[0057] Specifically, the fixing support 7 can include a plurality of connecting rods arranged along the circumference of the gas storage float pipe 1, and each connecting rod has a clamping structure at each end, and the two clamping structures can be clamped on the gas storage float pipe 1 and the storage pipe 2 respectively, so as to realize the relative fixation of the gas storage float pipe 1 and the storage pipe 2, and ensure that the radial distance of the storage pipe 2 and the gas storage float pipe 1 is consistent, and the height of the storage pipe 2 is higher than that of the gas storage float pipe 1, so that the gas storage float pipe 1 can be used as a channel for the staff to walk on the net cage, and the storage pipe 2 can be used as a handrail for the staff to walk on the gas storage float pipe 1, so as to ensure stable walking in the case of sea wave tossing, thereby facilitating the staff to check the feeding net cage on site.

[0058] It should be noted that other contents of the feeding net cage disclosed in the present application can refer to the prior art, which will not be described here.

[0059] The above is only an optional embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields within the technical concept of the present application, and the contents of the present application specification and drawings are included in the patent protection scope of the present application.
