[0016] A working method of an environment-controlled offshore cage aquaculture pipeline system, comprising the following working steps:

[0017] Step 1: When feeding, start the onshore air supply component and the feeding mechanism, transport the feed to the main pipeline through wind power, and input it into the branch pipeline through the connecting ring. The feed particles input by the air volume are gradually filled into the fixed sleeve, and the excess air volume is discharged upward through the bypass slot of the squeezing and pushing component, and the solid feed is accumulated in the fixed sleeve;

[0018] Step 2: When the filling is completed, the squeezing and pushing assembly is started, and the squeezing and pushing assembly moves down along the inside of the fixed sleeve and is sleeved on the central rod to complete the internal sealing of the fixed sleeve. As the squeezing and pushing assembly continues to move, the internal pressure of the fixed sleeve increases, and the pressure sensor senses that the pressure becomes larger and sends an electrical signal. The external control mechanism controls the outlet control assembly to move down, and the discharge port is connected with the side port, and seawater is poured into the fixed sleeve. The squeezing and pushing assembly continues to squeeze and push, and the feed mixture mixed with seawater is squeezed and ejected through the side port and the discharge port to complete the feeding of the feed;

[0019] Step 3: After the feeding is completed, the outlet control component moves upward and resets, and the side port is sealed, and the squeezing and pushing component moves in the opposite direction to reset the internal air pressure of the fixed sleeve. The pressure valve opens, and the fixed sleeve inhales air through the pressure valve and the pressure balance pipe to balance the internal air pressure of the fixed sleeve. The squeezing and pushing component moves upward and resets;

[0020] Step 4: When oxygen supplementation is needed, oxygen is directly input into the fixed casing through the main pipeline and the branch pipeline, and then input into the seawater through the bypass groove, bypass hole and bypass pipe to complete the oxygen replenishment. At the same time, when feeding the feed, when oxygen is used to transport the feed, as the feed is put into the aquaculture sea area, oxygen is simultaneously input into the seawater;

[0021] Step 5: When the outlet control component completes feeding and resets, the outlet is hidden in the protective seal to complete the outlet sealing protection.

[0022] The beneficial effects of the present invention are as follows:

[0023] (1) The present invention realizes effective collection of solid feed transported by airflow by utilizing a squeezing and pushing assembly, a center rod, a side port and an outlet control assembly. When feeding the aquaculture waters of the offshore cage area, it ensures that the solid feed is collected inside the seawater and isolated from the seawater before feeding. After a certain amount of feed is accumulated, according to actual conditions, rapid feeding is uniformly carried out in the water area below the sea surface, thereby avoiding the problem that when the feed introduced by the airflow is directly introduced into the seawater, the seawater blocks the discharge port and is difficult to effectively disperse. With the power of squeezing and spraying, on the one hand, centralized discharge after isolating the seawater underwater can be realized, and on the other hand, ejection discharge can be realized during centralized discharge, thereby enhancing the spraying mixing effect after the feed is mixed with the seawater, thereby greatly improving the underwater feed feeding effect of the aquaculture pipeline system in the offshore cage aquaculture waters.

[0024] (2) By reusing the filtration chamber formed by the branch pipeline, the fixed sleeve, and the extrusion component, when oxygenation of the aquaculture sea area is required, by directly inputting oxygen into the feeding path of the feed, and with the guidance of the bypass hole and the bypass pipe, oxygen can be directly input into the target water area. On the one hand, there is no need to install additional oxygenation pipelines, and on the other hand, the airflow cleaning of the residual feed inside the pipeline can be achieved. Moreover, when both oxygenation and feed feeding need to be processed, by using oxygen to replace air input, the synchronous conduction treatment of oxygen and feed can be realized, improving the processing efficiency of the aquaculture pipeline system.

[0025] (3) By reusing the movement control of the outlet control component, after the feed feeding is completed, with the downward reset of the sleeve, a relative extrusion effect is generated with the outer protective seal. On the one hand, friction cleaning at the outside of the discharge port is achieved after the feed feeding is completed, preventing aquatic organisms from attaching to the outside of the sleeve. On the other hand, the discharge port is directly sealed by the collar, eliminating the blockage effect on the discharge port, further improving the use stability of the pipeline system after underwater feed feeding, reducing the subsequent pipeline cleaning process, and having good use effects.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 10 As shown, an embodiment of the present invention provides an environment-controlled offshore cage aquaculture pipeline system and a working method thereof, comprising a main pipeline 3 and a wire-controlled pipeline 4, one end of the main pipeline 3 is fixedly connected to a connecting ring 1, the inner wall of the connecting ring 1 is fixedly connected to a branch pipeline 5, the outer side of the branch pipeline 5 is fixedly sleeved with a fixed sleeve 6, the outer side of the fixed sleeve 6 is movably sleeved with an outlet control component 7, the interior of the fixed sleeve 6 is fixedly connected with a center rod 9, the interior of the fixed sleeve 6 is provided with a squeezing and pushing component 10, and the squeezing and pushing component 10 is sleeved on the outer side of the branch pipeline 5, A side opening 13 is provided on the outer side surface of the fixed sleeve 6, and the squeezing and pushing assembly 10 includes a movable ring plug 101, an electric push rod 102 and a bypass groove 103. A sealing strip 14 is fixedly provided around the inner wall of the fixed sleeve 6, and the sealing strip 14 is adapted to the bypass groove 103. The outlet control assembly 7 includes a sleeve 71, a pressure balance pipe 72, a discharge port 73 and an electric push rod 74. The side opening 13 is located on the moving path of the discharge port 73. When the internal pressure of the fixed sleeve 6 increases, the outlet control assembly 7 moves downward and is connected to the inside of the fixed sleeve 6.

[0039] Embodiment 1: When feeding, start the onshore air supply assembly and the feeding mechanism, transport the feed to the main pipeline 3 by wind power, and input it into the branch pipeline 5 through the connecting ring 1, and the feed particles input by the air volume are gradually filled into the fixed sleeve 6, and the excess air volume is discharged upward through the bypass groove 103 of the squeezing and pushing assembly 10, and the solid feed is accumulated in the fixed sleeve 6. When the filling is completed, start the squeezing and pushing assembly 10, and the electric push rod 2 102 in the squeezing and pushing assembly 10 pushes the movable ring plug 101 to move downward, and moves downward along the inside of the fixed sleeve 6, and is sleeved on the center rod 9, and the bypass groove 103 is sleeved with the sealing strip 14 to complete the internal sealing of the fixed sleeve 6. As the squeezing and pushing assembly 10 continues to move, the internal pressure of the fixed sleeve 6 increases. The pressure sensor 11 senses that the pressure becomes larger and sends out an electrical signal. The external control mechanism controls the outlet control component 7 to start, and the electric push rod 74 pushes the sleeve 71 downward, the discharge port 73 is connected with the side port 13, and seawater is poured into the fixed sleeve 6. The squeezing and pushing component 10 continues to squeeze and push, and the feed mixture mixed with seawater is squeezed and ejected through the side port 13 and the discharge port 73 to complete the feeding of the feed. After the feeding is completed, the outlet control component 7 moves up and resets, and seals the side port 13, and moves in the opposite direction to reset the squeezing and pushing component 10, the internal air pressure of the fixed sleeve 6 is reduced, the pressure valve 12 is opened, and the fixed sleeve 6 inhales the air on the sea surface through the pressure valve 12 and the pressure balance pipe 72, and balances the internal air pressure of the fixed sleeve 6, and the squeezing and pushing component 10 moves up and resets normally.

[0040] Firstly, by utilizing the squeezing and pushing assembly 10, the center rod 9, the side opening 13 and the outlet control assembly 7, the solid feed transported by the airflow is effectively collected, and when feeding the aquaculture waters in the offshore cage area, it is ensured that the solid feed is collected inside the seawater and isolated from the seawater before feeding. After accumulating a certain amount of feed, according to the actual situation, the feed is quickly fed uniformly in the water area below the sea surface, so as to avoid the problem that when the feed introduced by the airflow is directly introduced into the seawater, the seawater closes the discharge port and is difficult to effectively disperse. With the power of squeezing and spraying, on the one hand, the centralized export after isolating the seawater underwater can be realized, and on the other hand, the ejection discharge during the centralized export can be realized, so as to enhance the spraying mixing effect after the feed is mixed with the seawater, and greatly improve the underwater feed feeding effect of the aquaculture pipeline system in the offshore cage aquaculture waters.

[0041] Embodiment 2: When oxygen supplementation is needed, oxygen is directly input into the fixed sleeve 6 through the main pipe 3 and the branch pipe 5, and is input into the seawater through the bypass groove 103, the bypass hole 16 and the bypass pipe 8 to complete the oxygen replenishment; at the same time, when feeding the feed, oxygen is used instead of air to transport the feed. As the feed is put into the aquaculture sea area, the transport oxygen is simultaneously input into the seawater to complete the quick treatment.

[0042] Firstly, by reusing the filter chamber surrounded by the branch pipeline 5, the fixed sleeve 6 and the squeezing and pushing assembly 10, when it is necessary to increase oxygen in the aquaculture sea area, by directly inputting oxygen into the delivery path for feeding the feed, with the guidance of the bypass hole 16 and the bypass pipe 8, the oxygen can be directly input into the target waters. On the one hand, there is no need to transfer the aeration pipeline, and on the other hand, the airflow cleaning of the residual feed inside the pipeline is realized. Moreover, when both the aeration and the feeding of the feed need to be processed, the oxygen is used to replace the air input, so that the simultaneous conduction processing of oxygen and the feed can be realized, thereby improving the processing efficiency of the aquaculture pipeline system.

[0043] Embodiment 3: When the outlet control assembly 7 is reset after completing feeding, the discharge port 73 is hidden in the protective seal 15, and the sleeve ring 152 seals the discharge port 73. At the same time, the attachment on the outer side of the sleeve 71 is pushed and cleaned when it moves relative to the sleeve ring 152, thereby completing the outlet sealing and protection.

[0044] Firstly, by utilizing the mobile control of the outlet control assembly 7 again, after the feeding is completed, the sleeve 71 is moved downward and reset to produce a relative squeezing and pushing effect with the outer protective seal 15. On the one hand, friction cleaning of the outer side of the discharge port 73 is achieved after the feeding is completed to prevent aquatic organisms from adhering to the outer side of the sleeve 71. On the other hand, the discharge port 73 is directly sealed with the collar 152 to eliminate the blockage of the discharge port 73, further improving the stability of the use of the pipeline system after underwater feed feeding, reducing the subsequent cleaning process of the pipeline, and achieving good use effect.

[0045] The top of the connecting ring 1 is fixedly connected with a wiring ring 2 , the side of the wiring ring 2 is connected with the wire control pipeline, and the branch pipelines 5 are distributed on the inner wall of the connecting ring 1 in a circular shape with equal intervals.

[0046] By utilizing the wiring ring 2 and the wire control pipeline 4, the control circuits are arranged and conducted, thereby facilitating the protection of the control, power and sensor circuits.

[0047] The bypass grooves 103 are arranged at equal intervals around the outer surface of the movable ring plug 101 , the movable ring plug 101 is movably sleeved in the fixed sleeve 6 , the electric push rod 102 is fixed in the fixed sleeve 6 , and the movable end is fixedly connected to the movable ring plug 101 .

[0048] By utilizing the bypass groove 103, air separation is achieved after the air is introduced into the feed, the solid feed is collected in the fixed sleeve 6, and the conveying air is guided to be discharged upward. When the squeezing and pushing component 10 moves downward, it cooperates with the sealing strip 14 to seal the fixed sleeve 6, thereby increasing the pressure under the internal squeezing and pushing, and cooperating with the seawater mixed with the subsequent feed to extrude and spray it out.

[0049] A bypass hole 16 is opened at the top of the fixed sleeve 6, and a bypass pipe 8 is fixedly connected to the top of the fixed sleeve 6. One end of the bypass pipe 8 is connected to the bypass hole 16, and the other end is vertically downward.

[0050] The bypass hole 16 and the bypass pipe 8 cooperate to input the separated air into the seawater. When the input air is oxygen, the oxygen enrichment process is completed simultaneously.

[0051] A reserved space is provided between the center rod 9 and the branch pipe 5 , the diameter of the center rod 9 is the same as the diameter of the lower end of the branch pipe 5 , the center axis of the center rod 9 and the lower end of the branch pipe 5 are consistent, and an inclined surface is provided on the top of the center rod 9 .

[0052] By adapting the center rod 9 and the branch pipeline 5, space is reserved to facilitate the downward movement of the feed, and when the movable ring plug 101 moves downward, it is sleeved with the center rod 9 and cooperates with the sleeve of the outer sealing strip 14 to ensure sealing during the squeezing and pushing process. After the side port 13 is opened and mixed with seawater, effective squeezing and spraying are achieved.

[0053] Among them, the sleeve 71 is movably sleeved on the outside of the fixed sleeve 6, one end of the electric push rod 74 is fixed to the bottom of the fixed sleeve 6, and the movable end is fixedly connected to the inside of the sleeve 71, one end of the pressure balance pipe 72 is fixedly sleeved in the sleeve 71, and the other end extends upward to above the water surface, and the discharge port 73 is opened on the outside of the sleeve 71.

[0054] The outlet control assembly 7 controls the connection with the side opening 13 by moving up and down. When connected, the internal seal of the fixed sleeve 6 is released and seawater is poured in. When sealed, the fixed sleeve 6 is isolated to ensure that the feed is isolated from the seawater when it is concentrated and pre-stored in the seawater.

[0055] A pressure sensor 11 and a pressure valve 12 are respectively embedded at the bottom of the fixed sleeve 6 , and the pressure valve 12 opens when the pressure in the fixed sleeve 6 decreases.

[0056] The pressure in the fixed sleeve 6 is sensed by the pressure sensor 11. When the pressure rises, an electrical signal is sent out, and in cooperation with the external control mechanism, the start-up of the outlet control component 7 is controlled. The pressure valve 12 opens when the fixed sleeve 6 is under negative pressure, ensuring that air is added to the fixed sleeve 6 when the squeezing and pushing component 10 moves upward, so as to avoid the squeezing and pushing component 10 being unable to move upward and reset.

[0057] Among them, the outer side of the outlet control component 7 is provided with a protective seal 15, which is fixedly connected to the bypass pipe 8. The protective seal 15 includes a connecting plate 151, a ring 152 and a connecting arc plate 153. The ring 152 is fixed on the side of the connecting plate 151 at equal intervals, the top of the connecting plate 151 is fixedly connected to the connecting arc plate 153, and the connecting arc plate 153 is fixedly sleeved with the bottom of the bypass pipe 8.

[0058] By utilizing the protective seal 15 in conjunction with the moving outlet control assembly 7, the surface cleaning is completed and the surface attachments are removed under relative movement to achieve cleaning.

[0059] The width of the collar 152 is the same as the length of the discharge port 73 , and the collar 152 is located on the moving path of the discharge port 73 .

[0060] And by using the sleeve ring 152 of matching size, the moved sleeve ring 152 seals the discharge port 73, thereby achieving sealing protection after cleaning.

[0063] Step 2: After the filling is completed, the squeezing and pushing component 10 is started, and the squeezing and pushing component 10 moves down along the inside of the fixed sleeve 6 and is sleeved on the central rod 9 to complete the internal sealing of the fixed sleeve 6. As the squeezing and pushing component 10 continues to move, the internal pressure of the fixed sleeve 6 increases, and the pressure sensor 11 senses that the pressure becomes larger and sends an electrical signal. The external control mechanism controls the outlet control component 7 to move down, and the discharge port 73 is connected with the side port 13, and seawater is poured into the fixed sleeve 6. The squeezing and pushing component 10 continues to squeeze and push, and the feed mixture mixed with seawater is squeezed and ejected through the side port 13 and the discharge port 73 to complete the feeding of the feed;

[0064] Step 3: After the feeding is completed, the outlet control component 7 moves upward and resets, and seals the side port 13, and moves in the opposite direction to reset the squeezing and pushing component 10, the air pressure inside the fixed sleeve 6 decreases, the pressure valve 12 opens, the fixed sleeve 6 inhales air through the pressure valve 12 and the pressure balance pipe 72, and balances the air pressure inside the fixed sleeve 6, and the squeezing and pushing component 10 moves upward and resets;

[0065] Step 4: When oxygen supplementation is needed, oxygen is directly input into the fixed sleeve 6 through the main pipe 3 and the branch pipe 5, and then input into the seawater through the bypass groove 103, the bypass hole 16 and the bypass pipe 8, so as to complete the oxygen supplementation. At the same time, when feeding the feed, when oxygen is used to transport the feed, oxygen is simultaneously input into the seawater as the feed is put into the aquaculture sea area;

[0066] Step 5: When the outlet control assembly 7 is reset after the feed is fed, the outlet 73 is hidden in the protective seal 15, completing the outlet sealing protection.

A method for operating an environment-controlled offshore cage aquaculture pipeline system according to any one of claims 1 to 9, characterized in that: The following steps are included: The first step: when feeding, the onshore air supply component and the feeding mechanism are started, the feed is transported to the main pipeline (3) by wind power, and is input into the branch pipeline (5) through the connecting ring (1), the feed particles input by the air volume are gradually filled into the fixed sleeve (6), and the excess air volume is discharged upward through the bypass groove (103) of the squeezing and pushing component (10), and the solid feed is accumulated in the fixed sleeve (6); Step 2: After the filling is completed, the squeezing and pushing component (10) is started, and the squeezing and pushing component (10) moves downward along the inside of the fixed sleeve (6) and is sleeved on the central rod (9), completing the sealing of the inside of the fixed sleeve (6). As the squeezing and pushing component (10) continues to move, the pressure inside the fixed sleeve (6) increases, and the pressure sensor (11) senses that the pressure becomes larger and sends an electrical signal. The external control mechanism controls the outlet control component (7) to move downward, and the discharge port (73) is connected to the side port (13), and seawater is poured into the fixed sleeve (6). The squeezing and pushing component (10) continues to squeeze and push, and the feed mixture mixed with the seawater is squeezed and sprayed out through the side port (13) and the discharge port (73), completing the feeding of the feed; Step 3: After the feeding is completed, the outlet control component (7) moves upward and resets, and seals the side opening (13), and moves the pushing component (10) in the opposite direction to reset the internal air pressure of the fixed sleeve (6), and the pressure valve (12) opens. The fixed sleeve (6) inhales air through the pressure valve (12) and the pressure balance pipe (72), and balances the internal air pressure of the fixed sleeve (6), and the pushing component (10) moves upward and resets; Step 4: When oxygen supplementation is required, oxygen is directly input into the fixed sleeve (6) through the main pipe (3) and the branch pipe (5), and then input into the seawater through the bypass groove (103), the bypass hole (16) and the bypass pipe (8), thereby completing the oxygen supplementation. At the same time, when feeding feed, oxygen is used to transport feed, and oxygen is simultaneously input into the seawater as the feed is put into the aquaculture sea area; Step 5: When the outlet control component (7) completes feeding, it is reset, and the outlet (73) is hidden in the protective seal (15), completing the outlet sealing protection.
