[0031] Please refer to Figure 1 , Figure 2 and Figure 3 , this embodiment discloses a two-way live fish loading and unloading system, including a two-way live fish conveying device 100, a first water inlet pipe 210, a second water inlet pipe 220, a first suction and discharge pipe 310, a second suction and discharge pipe 320, a high-pressure water pump 510 and a control box 400. The two-way live fish conveying device 100 includes a hollow outer cylinder 110, a throat pipe 120 and a protective net 130. A partition 111 is provided in the middle of the outer cylinder 110. A first opening 114 is provided at the first end of the outer cylinder 110, and a second opening 115 is provided at the second end of the outer cylinder 110. First water inlets 117 and second water inlets 118 are provided on the side wall of the outer cylinder 110 on opposite sides of the partition 111 respectively. The throat pipe 120 is installed in the outer cylinder 110 and penetrates through the partition 111. The protective net 130 is connected to the throat pipe 120 and the first opening 114 and the second opening 115; the first water inlet pipe 210 is connected to the first water inlet 117, the second water inlet pipe 220 is connected to the second water inlet 118, the first suction and discharge pipe 310 is connected to the first opening 114, and the second suction and discharge pipe 320 is connected to the second opening 115; a first valve 211 is provided on the first water inlet pipe 210, a second valve 221 is provided on the second water inlet pipe 220, and both the first water inlet pipe 210 and the second water inlet pipe 220 are connected to the high-pressure water pump 510; the control box 400 is electrically connected to the first valve 211 and the second valve 221 respectively. By turning on the high-pressure water pump 510 through the control box 400 and opening the first remote control valve 211 or the second valve 221, high-pressure water flow with fast flow rate is injected into the first water inlet pipe 210 or the second water inlet pipe 220. Due to the fast flow rate of the high-pressure water flow, under the division of the partition 111, it quickly flows out from one end, thereby forming a negative pressure area at the other end, forming a continuous fish suction channel; the live fish are sucked into the channel along the protective net 130, thus completing the suction of the fish catch; the fish catch follows the fluid in the channel and jets out from the other end, and is discharged through the second suction and discharge pipe 320 or the first suction and discharge pipe 310, completing the loading and unloading process of the live fish. Adopting the two-way jet mode, by switching the water inlet pipe, the two-way loading and unloading of live fish can be completed without moving and reversing the live fish conveying device 100, reducing the damage of the fish suction pump to the fish body and improving the loading and unloading efficiency.

[0032] Please continue to refer to Figure 1, flow meters 212 are provided on both the first water inlet pipe 210 and the second water inlet pipe 220, and the flow meters 212 are electrically connected to the control box 400. By using the flow meters 212 to measure the water flow rate and understand the flow conditions of the fluid medium in the pipeline, the operating states of the first water inlet pipe 210 and the second water inlet pipe 220 can be monitored, and faults and abnormalities of the pipeline and related devices can be detected at the earliest time; thus, the working states of the first valve 211 or the second valve 221 can be adjusted through the water flow rate to ensure the efficiency of live fish loading and unloading.

[0033] Please refer to Figure 1 , vacuum pressure gauges 311 are provided on both the first suction and discharge pipe 310 and the second suction and discharge pipe 320, and the vacuum pressure gauges 311 are electrically connected to the control box 400. When loading and unloading live fish, when the water surface in the culture tank 600 or the transportation tank 500 is close to the sea level, the pressure measured by the vacuum pressure gauge 311 is close to the atmospheric pressure, and the high-pressure water pump 510 is started and the first remote control valve 211 or the second remote control valve 221 is opened until the live fish loading and unloading work is completed.

[0034] Please refer to Figure 2 and Figure 3 , the outer cylinder is divided by a partition 111 to form a first water flow area 112 and a second water flow area 113. A guiding surface 116 is provided outside the outer cylinder 110 and adjacent to the positions of the first opening 114 and the second opening 115. The first end of the throat pipe 120 communicates with the first water flow area 112, and the second end of the throat pipe 120 communicates with the second water flow area 113. Inject a fast-flowing high-pressure water flow into the first water inlet pipe 210 or the second water inlet pipe 220. Due to the fast flow rate of the high-pressure water flow, it flows out quickly from one end under the division of the partition 111, thus forming a negative pressure area at the other end to form a continuous fish suction channel; the live fish are sucked into the channel along the protection net 130, thereby completing the suction of the catch.

[0035] Please refer to Figure 2 and Figure 3 , the outer cylinder 110 includes a first sub-cylinder 150 and a second sub-cylinder 160. The first sub-cylinder 150 and the second sub-cylinder 160 are connected and mirror-symmetrical in structure. The first sub-cylinder 150 is connected to the first suction and discharge pipe 310, and the second sub-cylinder 160 is connected to the second suction and discharge pipe 320. By adopting the two-way jet method, by switching the water inlet pipe, the two-way live fish loading and unloading work can be completed without moving and reversing the two-way jet live fish loading and unloading device, reducing the damage of the fish suction pump to the fish body and improving the loading and unloading efficiency.

[0036] Please refer to Figure 2, the protective net 130 can be an integral structure. The protective net 130 is connected to the inner wall of the throat pipe 120. The first end of the protective net 130 is connected to the first opening 114, and the second end of the protective net 130 is connected to the second opening 115. The outer wall of the protective net 130 is connected to the inner wall of the throat pipe 120, so that a continuous channel can be formed to reduce the damage caused by live fish transportation. Please refer to Figure 3 , the protective net 130 can also be a segmented structure. For example, the protective net 130 includes a first subnet 131 and a second subnet 132. The two ends of the first subnet 131 are respectively connected to the first opening 114 and the throat pipe 120, and the two ends of the second subnet 132 are respectively connected to the second opening 115 and the throat pipe 120. In this way, a protective structure can be formed between the throat pipe 120 and the outer cylinder 110, and a bearing structure can be formed between the throat pipe 120 and the first opening 114 and the second opening 115 of the outer cylinder 110, which can not only allow high-pressure water flow to flow out, but also reduce the damage caused by the collision between the live fish and the throat pipe 120 when the live fish enters the throat pipe 120.

[0037] Please refer to Figure 3 , the first flange 121 is provided at both the first opening 114 and the second opening 115, and the second flange 122 is provided at both the first water inlet 117 and the second water inlet 118. For example, a connecting flange I is provided at the first opening 114, and a connecting flange II is provided at the first water inlet 117. During use, the first water inlet pipe 210 is butted against the connecting flange I, and the first suction and discharge pipe 310 is butted against the connecting flange II, and is locked and fixed by fasteners such as screws and bolts. The connection is convenient and reliable, and is easy to disassemble.

[0038] Please refer to Figure 4 , when unloading live fish from the transportation tank 500 to the breeding tank 600, the second remote control valve 221 is opened through the control box 400 and the high-pressure water pump 510 is started. Water quickly flows into the outer cylinder 110 from the second water inlet 118. The partition 111 has a partitioning effect, and the pressurized water quickly flows out from the second opening 115, thereby forming a negative pressure at the first opening 114. At this time, the fish-water mixture is transported to the breeding tank 600 via the first opening 114, the throat pipe 120, the second opening 115 and the second suction and discharge pipe 320. After the transportation is stable, the high-pressure water pump 510 and the second remote control valve 221 are shut down. Using the siphon principle, the fish-water mixture will flow to the breeding tank 600 by gravity. It should be noted that in order to avoid fish stranding, seawater can be appropriately supplemented into the transportation tank 500 when necessary. When the water surface in the breeding tank 600 is close to the sea level, the high-pressure water pump 510 is started again and the second remote control valve 221 is opened until the live fish unloading work is completed.

[0039] Please refer to Figure 5, when loading live fish from the culture tank 600 into the transport tank 500, the first remote control valve 211 is opened through the control box 400 and the high-pressure water pump 510 is started. Water quickly flows into the outer cylinder 110 from the first water inlet 117. The partition 111 has a blocking effect, and the pressurized water quickly flows out from the first opening 114, thereby forming a negative pressure at the second opening 115. At this time, the fish-water mixture is transported to the transport tank 500 via the second opening 115, the throat pipe 120, the first opening 114, and the first suction and discharge pipe 310. After the transportation is stable, the high-pressure water pump 510 and the first remote control valve 211 are shut down. Using the siphon principle, the fish-water mixture will flow into the transport tank 500 by gravity. It should be noted that to avoid fish stranding, seawater can be appropriately supplemented into the culture tank 600 when necessary. To maintain an appropriate fish-water ratio, a seawater overflow pipe is provided on the upper side wall of the transport tank 500. When the water level in the transport tank 500 is close to the sea level, the high-pressure water pump 510 is started again and the first remote control valve 211 is opened until the live fish loading work is completed.

[0040] This live fish two-way loading and unloading system combines the advantages of gravity flow and jet flow transportation, reduces the damage to live fish, and has high loading and unloading efficiency. The circulating water pump configured on the live fish transport ship is used as the high-pressure water pump 510, which reduces the system investment cost. The two-way live fish conveying device 100 and equipment such as the high-pressure water pump 510 are arranged at the bottom of the tank, without occupying the space of the main deck, maximizing the deck cargo space. When loading and unloading live fish, only by connecting the live fish transport ship and the aquaculture ship through a hose, the loading and unloading of live fish between the transport tank 500 and the culture tank 600 can be realized. The layout is flexible and the operation is convenient. Only by observing the liquid level and operating the control box 400 can the live fish loading and unloading be completed. The degree of automation is high, reducing the labor intensity of the staff and improving the live fish loading and unloading efficiency.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
