When these elements are in the position shown in the drawings, these descriptions are appropriate. If the position of these elements changes, the indication of direction also changes accordingly.

[0046] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0047] Please refer to Figure 1 As shown in the drawings, the sea lice removing barge of the present application embodiment is used for sea lice removing operation of fish in the culture net cage 100. It can be understood that the barge can also be replaced by other types of marine platforms.

[0048] Please refer to Figure 1 The sea lice removing barge includes a barge platform 10 and a fish inlet system 20, a fish outlet system 30, a water body circulation system 40 and a water body treatment system 50 arranged on the barge platform 10.

[0049] As Figure 1 shown, the barge platform 10 can have a generally rectangular shape. When it is necessary to remove sea lice from fish in the culture net cage 100, the barge platform 10 can be docked at the side of the culture net cage 100. The rectangular shape can make the barge platform 10 as close as possible to the culture net cage 100 to shorten the fish transport distance. It can be understood that in other embodiments, the barge platform 10 can also be designed in other shapes, for example, a boat shape.

[0050] Please refer to Figure 1The barge platform 10 is provided with a medicated bath tank 11. The medicated bath tank 11 is used to hold seawater with lice-killing medicine for fish in need of lice-killing to soak in the medicated bath tank 11. After the fish soak in the medicated bath tank 11 for a predetermined time, the sea lice parasitic on the fish will die and fall off the fish, thereby achieving the purpose of killing the sea lice.

[0051] As shown in Figure 1 , the medicated bath tank 11 can be arranged at the middle position of the barge platform 10. The medicated bath tank 11 can be rectangular. The rectangular shape can realize the arrangement of a medicated bath tank 11 with a larger capacity in the limited space of the barge platform 10. It can be understood that in other embodiments, the medicated bath tank 11 can also be designed in other shapes, such as circular or polygonal, etc.

[0052] Referring to Figure 1 , in some embodiments, two medicated bath tanks 11 can be arranged on the barge platform 10, and the two medicated bath tanks 11 can be arranged side by side. The two medicated bath tanks 11 can be alternately used for fish feeding and fish discharging as needed, so as to avoid the fish density in one medicated bath tank 11 being too high or too low, thereby facilitating to ensure the fish to be fully medicated and protect the health of the fish.

[0053] It can be understood that in other embodiments, one or more than three medicated bath tanks 11 can also be arranged on the barge platform 10, which can be determined according to the situation.

[0054] Referring to Figure 1 , in the present application, the fish feeding system 20 is connected between the culture net cage 100 and the medicated bath tank 11, and is used to transport the fish in the culture net cage 100 to the medicated bath tank 11 for medicated bath.

[0055] For example, in some embodiments, the fish feeding system 20 can include a first fish suction pump 21 and a first fish-water separator 22. The first fish suction pump 21 is configured to suck the fish in the culture net cage 100 to the first fish-water separator 22. The first fish-water separator 22 is provided with a first fish outlet 23 communicated to the medicated bath tank 11.

[0056] Among them, the first fish suction pump 21 can be a vacuum fish suction pump. As shown in Figure 1 and Figure 2 , the inlet of the first fish suction pump 21 can be communicated to the culture net cage 100 through a pipeline, and the outlet of the first fish suction pump 21 can be communicated to the inlet 221 of the first fish-water separator through a pipeline.

[0057] It can be understood that when the first fish pump 21 extracts the fish in the net cage 100, the fish and seawater will be extracted together. The first fish-water separator 22 can be used to separate the fish and seawater extracted by the first fish pump 21, so as to avoid the external seawater from entering the medicated bath tank 11 and affecting the concentration of the medicament in the tank. Specifically, the fish and seawater enter the first fish-water separator 22 through the inlet 221 of the first fish-water separator, and the separated seawater can return to the external seawater through the water outlet 222 of the first fish-water separator. The separated fish can enter the medicated bath tank 11 through the first fish outlet 23 for medicated bath.

[0058] Exemplarily, as shown in Figure 1 and Figure 2 When the medicated bath tank 11 is two, the first fish outlet 23 can be provided as two. The two first fish outlets 23 are in communication with the two medicated bath tanks 11 one by one. The two first fish outlets 23 can be opened alternatively, so that the two medicated bath tanks 11 can be alternately filled with fish as needed, avoiding that the fish density in one of the medicated bath tanks 11 is too high or too low.

[0059] Referring to Figure 2 In an embodiment, the fish inlet system 20 comprises a reversing valve 24, which is arranged at the two first fish outlets 23 of the first fish-water separator 22 and is used to control the two first fish outlets 23 to be opened alternatively. For example, when the fish density in one of the medicated bath tanks 11 is relatively high, the first fish outlet 23 in communication with the medicated bath tank 11 can be closed by the reversing valve 24, and the other first fish outlet 23 is opened. Then, the first fish pump 21 and the first fish-water separator 22 can fill the other medicated bath tank 11 with fish through the other first fish outlet 23.

[0060] The reversing valve 24 can be an electromagnetic reversing valve. Alternatively, in other embodiments, the reversing valve 24 can also be a pneumatic or manual reversing valve.

[0061] Alternatively, in other embodiments, the reversing valve 24 can be omitted. At the same time, a switch valve can be arranged at each first fish outlet 23, and the opening or closing of the corresponding first fish outlet 23 can be controlled by the switch valve. Alternatively, the switch valve can also be arranged on the pipeline connecting each first fish outlet 23 and the corresponding medicated bath tank 11, so as to indirectly realize the opening or closing of the first fish outlet 23. The specific arrangement can be determined according to the situation.

[0062] It should be noted that in other embodiments, the two first fish outlets 23 can be opened simultaneously, so that the first fish pump 21 and the first fish-water separator 22 can simultaneously fill the two medicated bath tanks 11 with fish through the two first fish outlets 23. The specific arrangement can be determined according to the situation.

[0063] It should be noted that in the embodiments of the present application, the fish inlet system 20 comprises a first fish suction pump 21 and a first fish-water separator 22. However, the present application is not limited thereto, and in other embodiments, the fish inlet system 20 can also omit the first fish-water separator 22, or the fish inlet system 20 can comprise other structures.

[0064] Referring to Figure 1 In the present application, the fish outlet system 30 is connected between the medicated bath pool 11 and the breeding net cage 100, and is used to transport the fish after medicated bath back to the breeding net cage 100. It can be understood that the breeding net cage 100 connected by the fish inlet system 20 and the breeding net cage 100 connected by the fish outlet system 30 are two independent net cages, so as to avoid confusion between the fish not medicated and the fish after medicated.

[0065] For example, in some embodiments, the fish outlet system 30 can comprise a second fish suction pump 31 and a second fish-water separator 32. The second fish suction pump 31 is configured to extract the fish in the medicated bath pool 11 to the second fish-water separator 32. The second fish-water separator 32 is provided with a second fish outlet 33 connected to the breeding net cage 100.

[0066] The second fish suction pump 31 can be a vacuum fish suction pump. As shown in Figure 1 、 Figure 3 and Figure 4 The inlet of the second fish suction pump 31 can be connected to the medicated bath pool 11 through a pipeline, and the outlet 311 of the second fish suction pump can be connected to the inlet 321 of the second fish-water separator through a pipeline.

[0067] It can be understood that when the second fish suction pump 31 extracts the fish in the medicated bath pool 11, the fish and the medicated bath pool water will be extracted together. The second fish-water separator 32 can be used to separate the fish extracted by the second fish suction pump 31 and the medicated bath pool water, so as to avoid the medicated bath pool water from being discharged into the external seawater. Specifically, the fish and the medicated bath pool water enter the second fish-water separator 32 through the inlet 321 of the second fish-water separator, and the separated medicated bath pool water can return to the medicated bath pool 11 through the drain 322 of the second fish-water separator. The separated fish can enter the breeding net cage 100 through the second fish outlet 33.

[0068] For example, as shown in Figure 1 and Figure 3 When the medicated bath pool 11 is two, the second fish suction pump 31 is provided with two fish suction pipelines 34 corresponding to the two medicated bath pools 11, and the two fish suction pipelines 34 are connected to the two medicated bath pools 11 one by one. The two fish suction pipelines 34 can be selectively conducted, so as to realize the alternation of the two medicated bath pools 11 according to the needs.

[0069] Referring to Figure 3In an embodiment, a first valve 341 is arranged on each fish suction pipeline 34, and the first valve 341 is used to control the opening and closing of the corresponding fish suction pipeline 34. For example, when the fish in one of the medicated bath pools 11 completes the medicated bath, the first valve 341 on the fish suction pipeline 34 connected to the medicated bath pool 11 can be opened, so that the second fish suction pump 31 can suck the fish in the medicated bath pool 11 to the second fish-water separator 32.

[0070] In an embodiment, the first valve 341 can be an electromagnetic valve. Alternatively, in other embodiments, the first valve 341 can also be a pneumatic valve or a manual valve.

[0071] Of course, in other embodiments, the first valve 341 on each fish suction pipeline 34 can be omitted. Meanwhile, the two fish suction pipelines 34 can be combined into one pipeline to be connected to the inlet of the second fish suction pump 31, and a three-way switch valve can be arranged at the intersection of the three pipelines. The three-way switch valve can realize the connection of any fish suction pipeline 34 to the inlet of the second fish suction pump 31, so as to realize the purpose of selectively conducting two fish suction pipelines 34.

[0072] It should be noted that in other embodiments, the two fish suction pipelines 34 can be simultaneously conducted. Thus, the second fish suction pump 31 can simultaneously suck the fish in the two medicated bath pools 11 through the two fish suction pipelines 34 and deliver the fish to the second fish-water separator 32, which can be determined according to the specific situation.

[0073] It should be noted that in the embodiment of the present application, the fish outlet system 20 includes the second fish suction pump 31 and the second fish-water separator 32. However, the present application is not limited thereto, and in other embodiments, the fish outlet system 30 can also include other structures, such as a buffer tank or a counter, etc.

[0074] Referring to Figure 1 , Figure 4 and Figure 5 In an embodiment, the sea lice removal barge further includes a second filter 36, the water inlet 361 of the second filter is connected to the water outlet 322 of the second fish-water separator, and the water outlet 362 of the second filter is connected to the medicated bath pools 11. Specifically, the water outlet 362 of the second filter can be connected to the two medicated bath pools 11 through two pipelines, and a backwater valve 364 for controlling the opening and closing of the two pipelines can be arranged on the two pipelines, respectively.

[0075] In the embodiment, the second filter 36 is used to receive the medicated bath pool water separated by the second fish-water separator 32, and the medicated bath pool water is filtered and then returned to the medicated bath pools 11. The second filter 36 can be a micro-filter for aquaculture, which can filter the sea lice and fish feces in the water discharged by the second fish-water separator 32. The second filter 36 can return the filtered water to the medicated bath pools 11, so as to realize the filtration and recycling of the medicated bath pool water, thereby avoiding waste.

[0076] As Figure 1 shown in the utility model, the fish entering system 20 and the fish exiting system 30 can be arranged at opposite sides of the medicated bath pool 11 respectively, so that the fish entering and exiting can be prevented from gathering. In an embodiment, the sea lice removing barge further comprises a fish driving device 60 arranged in the medicated bath pool 11, and the fish driving device 60 is used to drive the fish in the medicated bath pool 11 towards the side where the fish exiting system 30 is located.

[0077] Specifically, the fish driving device 60 can drive the fish in the medicated bath pool 11 towards the entrance of the fish suction pipeline 34. By arranging the fish driving device 60, the fish exiting efficiency can be improved, thereby facilitating the improvement of the removing efficiency of the sea lice removing barge.

[0078] Referring to Figure 1 Optionally, the fish driving device 60 comprises a plurality of fish driving plates 61, and the plurality of fish driving plates 61 are movably arranged in the medicated bath pool 11. For example, three fish driving plates 61 can be arranged in each medicated bath pool 11, wherein the width of one fish driving plate 61 can match the width of the medicated bath pool 11 and the fish driving plate 61 can move along the length direction of the medicated bath pool 11. The other two fish driving plates 61 can be arranged at positions close to the entrance of the fish suction pipeline 34 in the medicated bath pool 11, and one fish driving plate 61 can move up and down and the other fish driving plate 61 can move along the width direction of the medicated bath pool 11. Thus, the cooperation of the movement of the three fish driving plates 61 can efficiently drive the fish in the medicated bath pool 11 towards the entrance of the fish suction pipeline 34, thereby improving the fish driving efficiency.

[0079] Optionally, the fish driving plates 61 can be movably arranged in the medicated bath pool 11 in the following manner: a slide rail can be arranged on the side wall of the medicated bath pool 11, and a pulley is arranged on each fish driving plate 61 and can slide in the slide rail. Thus, the movement of the fish driving plates 61 in the medicated bath pool 11 can be realized through the slide rail and the pulley.

[0080] Of course, in other embodiments, the fish driving device 60 can also have other structures, for example, the fish driving device 60 is a fishing net movably arranged in the medicated bath pool 11. Alternatively, the fish driving device 60 can also be an ultrasonic fish driving device, etc.

[0081] Referring to Figure 1 shown in the utility model, the water circulation system 40 is mainly used to supplement the external seawater into the medicated bath pool 11 or circulate the water in the medicated bath pool 11, and filter and adjust the temperature of the seawater entering the medicated bath pool 11 or the water in the medicated bath pool 11. Specifically, the water circulation system 40 comprises a circulating pump 41, a first filter 42 and a heat exchanger 43. The circulating pump 41, the first filter 42 and the heat exchanger 43 are connected through pipelines.

[0082] As Figure 1As shown, the water inlet of the circulating pump 41 is connected to the medicated bath pool 11 and the external seawater respectively, and the water outlet of the circulating pump 41 is communicated with the water inlet of the first filter 42. The function of the circulating pump 41 is mainly to draw the external seawater or the medicated bath pool water in the medicated bath pool 11 into the medicated bath pool 11.

[0083] As shown, Figure 1 the water inlet of the first filter 42 is communicated with the water outlet of the circulating pump 41, and the water outlet of the first filter 42 is communicated with the water inlet of the heat exchanger 43. The first filter 42 is used to filter the water outlet of the circulating pump 41. The first filter 42 can be a microfilter for aquaculture, which can filter sea lice, fish feces and the like in the water outlet of the circulating pump 41, so as to improve the cleanliness of the water in the medicated bath pool 11. The pollutants such as sea lice and fish feces filtered by the first filter 42 can be collected at the drain port of the first filter 42 and then treated collectively.

[0084] As shown, Figure 1 the water inlet of the heat exchanger 43 is communicated with the water outlet of the first filter 42, and the water outlet of the heat exchanger 43 is communicated to the medicated bath pool 11. The heat exchanger 43 is used to adjust the temperature of the water outlet of the first filter 42, so that the water in the medicated bath pool 11 can be maintained at a suitable temperature for the survival and health of fish.

[0085] Referring to Figure 1 and Figure 6 In an embodiment, the water circulation system 40 includes a second valve 44, which is arranged on the pipeline in which the water inlet of the circulating pump 41 is communicated with the external seawater. The second valve 44 can be an electromagnetic valve. Alternatively, in other embodiments, the second valve 44 can also be a pneumatic valve or a manual valve.

[0086] Before the medicated bath starts, seawater needs to be added to the medicated bath pool 11. At this time, the second valve 44 can be opened, and the circulating pump 41 is started, so that the external seawater can be drawn by the circulating pump 41, and then filtered by the first filter 42 and adjusted in temperature by the heat exchanger 43 before entering the medicated bath pool 11. When the medicated bath pool 11 is filled with water, the second valve 44 can be closed, so that the medicated bath pool water can be drawn by the circulating pump 41, and then filtered by the first filter 42 and adjusted in temperature by the heat exchanger 43 before entering the medicated bath pool 11 to realize water circulation, so as to ensure that the temperature of the medicated bath pool water is suitable during the medicated bath, and the cleanliness of the medicated bath pool water is ensured.

[0087] Referring to Figure 1 and Figure 6In one embodiment, the water circulation system 40 comprises a seawater discharge branch 45, one end of the seawater discharge branch 45 is communicated with the water outlet of the first filter 42, and the other end of the seawater discharge branch 45 is communicated to the external seawater. By arranging the seawater discharge branch 45, the water in the bath pool 11 can be discharged to the external seawater after the medicated bath is finished, thereby reducing the burden of the barge. Since the seawater discharge branch 45 is connected to the water outlet side of the first filter 42, the water in the bath pool can be filtered by the first filter 42 before being discharged to the sea, thereby avoiding pollution of the marine environment.

[0088] The seawater discharge branch 45 can be provided with a third valve 451 for controlling the opening and closing of the seawater discharge branch 45. Thus, the seawater discharge operation of the bath pool water can be performed as needed through the third valve 451. The third valve 451 can be an electromagnetic valve. Alternatively, the third valve 451 can be a pneumatic or manual valve, etc.

[0089] It should be noted that in the present application, two sets of water circulation systems 40 can be arranged, and the two sets of water circulation systems 40 can be arranged to correspond to two bath pools 11 respectively, so as to supply seawater or circulate water in the two bath pools 11 respectively.

[0090] It should be noted that in the present application, before the water in the bath pool 11 is discharged to the sea after the medicated bath is finished, the water in the bath pool 11 needs to be harmless treated by the water treatment system 50. Details can be seen in the following description.

[0091] Referring to Figure 1 In the present application, the water treatment system 50 is mainly used for oxygenating the water in the bath pool 11, maintaining the oxygen content in the bath pool 11, and ensuring the health of the fish. In addition, the water treatment system 50 can also be used for harmless treatment of the bath pool water, so that the bath pool water can meet the seawater quality requirements, thereby avoiding pollution of the seawater environment.

[0092] For example, as shown in Figure 1 The water treatment system 50 comprises an oxygen generator 51 and an aeration device 52, the aeration device 52 is arranged in the bath pool 11, and the oxygen generator 51 is connected to the aeration device 52 through a pipeline to provide oxygen to the bath pool 11. The aeration device 52 can be an aeration disc. Alternatively, in other embodiments, the aeration device 52 can be a plurality of aeration pipes arranged at the bottom of the bath pool 11.

[0093] As shown in Figure 1 and Figure 7 The pipeline from the oxygen generator 51 to the aeration device 52 can be provided with a first air supply valve 511, so that the first air supply valve 511 can be used to supply oxygen to the bath pool 11 as needed.

[0094] Referring to Figure 1In one embodiment, the water body treatment system 50 further comprises an ozone machine 53 connected with the oxygen generator 51 and the aeration device 52 respectively. The ozone machine 53 is used to treat the oxygen generated by the oxygen generator 51 to form ozone, and provide the ozone into the medicated bath pool 11 through the aeration device 52.

[0095] As shown in Figure 1 and Figure 7 , the pipeline of the ozone machine 53 connected with the aeration device 52 can be provided with a second air supply valve 531, so that the ozone can be provided into the medicated bath pool 11 on demand through the second air supply valve 531.

[0096] It should be noted that in the present application, the aeration device 52 can be provided with two, and the two aeration devices 52 can be respectively arranged in the two medicated bath pools 11, and the two aeration devices 52 can be connected by pipelines. The oxygen generator 51 and the ozone machine 53 can provide oxygen and ozone to one of the aeration devices 52 respectively, and the oxygen and ozone can be circulated from the aeration device 52 to the other aeration device 52, so that the two medicated bath pools 11 can obtain oxygen and ozone.

[0097] The sea lice removing barge in the embodiment of the present application works as follows:

[0098] Before the medicated bath starts, the second valve 44 is opened, and the circulating pump 41 is started, so that the circulating pump 41 can draw seawater, filter the seawater through the first filter 42, adjust the temperature of the seawater through the heat exchanger 43, and then deliver the seawater into the corresponding medicated bath pool 11. When the seawater in the medicated bath pool 11 is replenished, the second valve 44 is closed.

[0099] When the medicated bath starts, the first fish pump 21 draws the fish and seawater in the net cage 100 into the first fish-water separator 22, the seawater is discharged through the drain port 222 of the first fish-water separator, and the fish enters the two medicated bath pools 11 through the two first fish outlets 23 respectively, and the reversing valve 24 can control the two first fish outlets 23 to be opened alternately.

[0100] Referring to Figure 1, the following will be described with two medicated bath pools 11 as medicated bath pool 11A and medicated bath pool 11B: when fish is introduced into medicated bath pool 11A, the reversing valve 24 opens the first fish outlet 23 corresponding to the medicated bath pool 11A and closes the first fish outlet 23 corresponding to the medicated bath pool 11B. When the fish density in the medicated bath pool 11A reaches the rated medicated bath density, the reversing valve 24 closes the first fish outlet 23 corresponding to the medicated bath pool 11A and opens the first fish outlet 23 corresponding to the medicated bath pool 11B, so that the fish enters the medicated bath pool 11B for medicated bath. When the fish in the medicated bath pool 11A completes the medicated bath and is driven by the fish driving device 60 to the inlet of the corresponding fish suction pipeline 34, the fish water in the medicated bath pool 11A can be extracted by the second fish suction pump 31 and transported to the second fish-water separator 32 for fish-water separation, and the separated fish is sent to the breeding net cage 100 through the second fish outlet 33. At this time, the fish density in the medicated bath pool 11B reaches the rated medicated bath density, the reversing valve 24 closes the first fish outlet 23 corresponding to the medicated bath pool 11B and opens the first fish outlet 23 corresponding to the medicated bath pool 11A, and the fish is transported to the medicated bath pool 11A. When the fish in the medicated bath pool 11B completes the medicated bath and is driven by the fish driving device 60 to the inlet of the corresponding fish suction pipeline 34, the fish water in the medicated bath pool 11B can be extracted by the second fish suction pump 31 and transported to the second fish-water separator 32 for fish-water separation, and the separated fish is sent to the breeding net cage 100 through the second fish outlet 33. At this time, the fish density in the medicated bath pool 11A reaches the rated medicated bath density, the reversing valve 24 closes the first fish outlet 23 corresponding to the medicated bath pool 11A and opens the first fish outlet 23 corresponding to the medicated bath pool 11B, and the fish is transported to the medicated bath pool 11B; so on and so forth, to complete the fish medicated bath and lice removal operation. The fish density in each medicated bath pool 11 can be counted and calculated by the fish counter arranged at each first fish outlet 23 and / or each fish suction pipeline 34.

[0101] During the medicated bath process, the water in the second fish-water separator 32 can be drained into the second filter 36 for filtration, and the filtered water in the medicated bath pool can be transported to the two medicated bath pools 11 through the water outlet 362 of the second filter. The sea lice, fish feces and other pollutants formed by the filtration of the second filter 36 can be collected at the sewage outlet 363 of the second filter and then treated.

[0102] During the medicated bath process, the second valve 44 remains closed and the circulating pump 41 is opened, so that the water in the medicated bath pool 11 is extracted by the circulating pump 41 and then reenters the medicated bath pool 11 after being filtered by the first filter 42 and being temperature-regulated by the heat exchanger 43, so as to circulate the water body and complete the filtration and temperature regulation of the water in the medicated bath pool.

[0103] During the medicating process, the first air supply valve 511 is opened, and the second air supply valve 531 is closed, so that the oxygen generated by the oxygen generator 51 can enter the two aeration devices 52 through the pipeline and diffuse into the pool water of the two medicating pools 11, so that the oxygen content in the medicating pool water is maintained at 8 mg / L.

[0104] After the medicating process is completed, the first air supply valve 511 is closed, and the second air supply valve 531 is opened, so that the oxygen generated by the oxygen generator 51 can be treated by the ozone generator 53 to form ozone, and the ozone can enter the two aeration devices 52 through the pipeline and diffuse into the pool water of the two medicating pools 11, so that the medicating pool water is harmlessly treated.

[0105] After the harmlessly treatment of the medicating pool water is completed, the third valve 451 is opened, so that the harmlessly treated medicating pool water can be extracted by the circulating pump 41 and filtered by the first filter 42 and then discharged to the external seawater through the seawater discharge branch 45.

[0106] The sea lice removing barge can fully medicate the fish in the medicating pool on the barge platform through the fish inlet system and the fish outlet system, and the medicated fish can be returned to the culture net cage, so that the sea lice on the fish can be effectively removed, and the pollution to the marine environment caused by directly putting medicaments into the culture net cage is avoided.

[0107] The sea lice removing barge can fully medicate the fish in the medicating pool on the barge platform through the fish inlet system and the fish outlet system, and the medicated fish can be returned to the culture net cage, so that the sea lice on the fish can be effectively removed, and the pollution to the marine environment caused by directly putting medicaments into the culture net cage is avoided.
