Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a vacuum fish suction device. Background Art

[0002] In the process of aquaculture, whether it is changing ponds, grading and stocking fish during their growth, or catching and transporting fish when they mature, it is necessary to quickly catch and transport fish from the breeding ponds, so as to improve the survival efficiency of fish and increase the catch.

[0003] Currently, a vacuum fish suction device is commonly used to quickly capture and transport fish. This device consists of a fish suction tank and a vacuum pump, which is connected to the aquaculture pond. The vacuum pump is connected to the tank to absorb air from the tank, creating a negative pressure in the tank. This negative pressure allows the tank to suck up water and fish from the aquaculture pond. Once the vacuum fish suction device has completed aspiration and transported the fish to its destination, the drain port at the bottom of the tank is opened, allowing the water and fish within to drain under gravity through the drain port into another aquaculture pond or a drainer, thereby rapidly capturing and transporting the fish and improving their survival rate.

[0004] However, the vacuum fish suction device can only perform a single capture and a single discharge of fish. It takes a long time to complete the capture and transportation of the entire fish in a single breeding pond, and the work efficiency is low. Utility Model Content

[0024] In the process of fish farming, whether it is changing ponds, grading and stocking fish during growth, or catching and transporting fish when they mature, it is necessary to catch fish from one breeding pond and then transport them to other breeding ponds or drainage structures, which can reduce working time and improve the efficiency of fish catching and transporting.

[0025] Figure 1 It is a structural schematic diagram of the vacuum fish suction device of the utility model.

[0026] See Figure 1 For the sake of ease of understanding and description, the state of the vacuum fish suction device when in use is used as a reference, and the up and down directions of the vacuum fish suction device are used as the up and down directions below.

[0027] Figure 2 The utility model is a structural schematic diagram of a first fish suction tank, a second fish suction tank, a vacuum component, a fish suction pipe and a fish discharge pipe.

[0028] See Figure 1 and Figure 2 The present application provides a vacuum fish suction device, which may include: a first fish suction tank 110, a second fish suction tank 120, and a vacuum assembly 200. The first fish suction tank 110 may have a first chamber for accommodating fish. The second fish suction tank 120 may have a second chamber for accommodating fish. The vacuum assembly 200 may include a first vacuum pump 210, a second vacuum pump 220, and a connector 230. The connector 230 has four connecting ports, which respectively connect to the first fish suction tank 110, the second fish suction tank 120, the first vacuum pump 210, and the second vacuum pump 220. The first vacuum pump 210 can be connected to the first fish suction tank 110 or the second fish suction tank 120 through the connector 230 to absorb gas, thereby creating a negative pressure in the first chamber or the second chamber. The second vacuum pump 220 can be connected to the first fish suction tank 110 or the second fish suction tank 120 via a connector 230 to input high-pressure gas to the first chamber or the second chamber to achieve a high-pressure state. One of the first chamber and the second chamber is in a negative pressure state, while the other is in a high pressure state.

[0029] When the vacuum fish suction device is operating, the first vacuum pump 210 is connected to the first fish suction tank 110 via the connector 230, and the second vacuum pump 220 is connected to the second fish suction tank 120 via the connector 230. The first fish suction tank 110 is placed under negative pressure by the first vacuum pump 210. Under this negative pressure, the first fish suction tank 110 can suck up and hold the fish and water in the aquaculture pond. The second fish suction pipe 120 is placed under high pressure by the second vacuum pump 220.

[0030] After the first chamber of the first fish suction tank 110 has sucked up and contained fish and water, the connector 230 is switched, connecting the first vacuum pump 210 to the second fish suction tank 120 via the connector 230, and the second vacuum pump 220 to the first fish suction tank 110 via the connector 230. The first fish suction tank 110 is placed in a high-pressure state by the second vacuum pump 220, allowing the fish and water in the first fish suction tank 110 to be discharged out of the first fish suction tank 110. The second fish suction tank 120 is placed in a negative-pressure state by the first vacuum pump 210, allowing it to suck up and contain fish and water in the aquaculture pond.

[0031] Under the action of the first vacuum pump 210, the second vacuum pump 220 and the connecting piece 230, the first fish suction tank 110 and the second fish suction tank 120 start to circulate fish suction and discharge, so as to effectively reduce the working time of the vacuum fish suction device, improve the efficiency of fish catching and transporting, and thus improve the efficiency of fish farming.

[0032] See Figure 1 and Figure 2 In this embodiment, the first fish suction tank 110 may include a first fish inlet 111 for fish to enter the first chamber and a first fish outlet 112 for discharging fish in the first chamber.

[0033] The first fish suction tank 110 can be cylindrical. A first fish inlet 111 and a first fish outlet 112 are located at either end of the first fish suction tank 110. The first fish inlet 111 is positioned above the first fish outlet 112. This allows the first fish outlet 112 to efficiently drain fish and water from the first chamber when the first fish suction tank 110 is draining fish, preventing any fish from remaining in the first chamber.

[0034] In some embodiments, the first fish suction tank 110 may include a body 114, a fish inlet 115, and a fish outlet 116. The fish inlet 115 and the fish outlet 116 are connected to opposite ends of the body 114 to form a can-like structure. The fish inlet 115 is provided with a first fish inlet 111, and the fish outlet 116 is provided with a first fish outlet 112.

[0035] As the fish outlet 116 moves away from the fish inlet 115, the fish outlet 116 has a tapered structure with a gradually decreasing cross-sectional area. The first row of fish openings 112 is located at the end of the fish outlet 116 away from the fish inlet 115 and at the bottom of the fish outlet 116. This allows the fish and water in the first chamber to be fully drained, preventing any fish from remaining in the first chamber.

[0036] In other embodiments, the first fish suction tank 110 may be tilted so that the first fish discharge port 112 is located at the bottom of the first fish suction tank 110 to fully discharge the fish.

[0037] See Figure 1 and Figure 2 In this embodiment, the first fish suction tank 110 may be provided with fish tank valves (not shown in the figure) at the first fish inlet 111 and the first fish outlet 112 to control the opening and closing of the first fish inlet 111 and the first fish outlet 112, so as to facilitate the first chamber to be in a negative pressure state under the action of the first vacuum pump 210 and to facilitate the first chamber to enter a high-pressure gas under the action of the second vacuum pump 220.

[0038] See Figure 1 and Figure 2 In this embodiment, a liquid level sensor 130 may be provided in the first fish suction tank 110. The liquid level sensor 130 can obtain the liquid level parameters in the first fish suction tank 110 in real time. The first fish suction tank 110 can be preset to a low liquid level preset position and a high liquid level preset position according to demand.

[0039] When the liquid level in the first fish suction tank 110 drops to a preset low liquid level, the first fish inlet 111 is opened, the first fish outlet 112 is closed, and the connector 230 is switched to connect the first fish suction tank 110 to the first vacuum pump 210. The first vacuum pump 210 extracts air from the first chamber, placing the first fish suction tank 110 in a negative pressure state and sucking in fish.

[0040] When the liquid level in the first fish suction tank 110 rises to a preset high liquid level, the first fish inlet 111 is closed, the first fish discharge port 112 is opened, and the connector 230 is switched to connect the first fish suction tank 110 with the second vacuum pump 220. The second vacuum pump 220 pumps high-pressure gas into the first chamber, maintaining a high pressure in the first fish suction tank 110 and discharging fish, thereby ensuring efficient fish discharge and preventing fish from remaining in the first fish suction tank 110.

[0041] See Figure 1 and Figure 2 In this embodiment, a pressure sensor 140 may be provided within the first fish suction tank 110. The pressure sensor 140 can obtain real-time pressure parameters within the first fish suction tank 110. The pressure sensor 140 can cooperate with the liquid level sensor 130 to enable the first fish suction tank 110 to switch between fish suction and fish discharge.

[0042] See Figure 1 and Figure 2 In this embodiment, the first fish suction tank 110 may be provided with a fish tank inspection door 113 and a fish tank observation hand hole (not shown in the figure) to facilitate inspection and maintenance by staff.

[0043] See Figure 1 and Figure 2In this embodiment, the second fish suction tank 120 includes a second fish inlet 121 for allowing fish to enter the second chamber and a second fish outlet 122 for discharging fish from the second chamber. The first fish suction tank 110 and the second fish suction tank 120 can be positioned adjacent to each other to reduce the size and footprint of the vacuum fish suction device, facilitating its flexible placement.

[0044] In some embodiments, the structure of the second fish suction tank 120 refers to the structure of the first fish suction tank 110 described above, so that the second fish suction tank 120 can suck and discharge fish; and the second fish suction tank 120 can cooperate with the first fish suction tank 110 to achieve cyclic discharge and suction of fish, thereby improving the efficiency of catching and transporting.

[0045] When the vacuum fish suction device is in use, the first fish inlet 111 is opened, the first fish outlet 112 is closed, the second fish inlet 121 is closed, and the second fish outlet 122 is opened. Then, the connecting piece 230 is switched to put the first fish suction tank 110 in a negative pressure state and the second fish suction tank 120 in a high pressure state, so that the first fish suction tank 110 can suck up and hold fish and water, and the second fish suction tank 120 can discharge fish and water.

[0046] When the liquid level in the first fish suction tank 110 rises to a preset high level and the liquid level in the second fish suction tank 120 drops to a preset low level, the first fish inlet 111 is closed, the first fish discharge port 112 is opened, the second fish inlet 121 is opened, and the second fish discharge port 122 is closed. Then, the connector 230 is switched to place the first fish suction tank 110 in a high-pressure state and the second fish suction tank 120 in a negative-pressure state. This allows the first fish suction tank 110 to discharge the fish and water, while the second fish suction tank 120 to suck up and store the fish and water. The first and second fish suction tanks 110, 120 cycle through fish suction and discharge, improving fish catching and transport efficiency, reducing production costs, and thus increasing fish farming efficiency.

[0047] See Figure 1 and Figure 2 In this embodiment, the vacuum assembly 200 may include a first vacuum pump 210, a second vacuum pump 220, and a connector 230. The first vacuum pump 210 is capable of extracting air from the first and second fish suction tanks 110, 120. The second vacuum pump 220 is capable of pumping high-pressure gas into the first and second fish suction tanks 110, 120. The connector 230 is provided with four connecting ports, which are respectively connected to the first and second fish suction tanks 110, 120, the first vacuum pump 210, and the second vacuum pump 220. This allows the connector 230 to be switched, thereby connecting the first and second vacuum pumps 210, 220, to the first and second fish suction tanks 110, 120, respectively.

[0048] In some embodiments, the connecting piece 230 can be a four-way valve, so that the first vacuum pump 210 can be optionally connected to the first fish suction tank 110 or the second fish suction tank 120, and the second vacuum pump 220 can be optionally connected to the second fish suction tank 120 or the first fish suction tank 110, thereby facilitating the cyclic suction and discharge of fish in the first fish suction tank 110 and the second fish suction tank 120.

[0049] In other embodiments, the first vacuum pump 210 and the second vacuum pump 220 are arranged near the first fish inlet 111 of the first fish suction tank 110 and the second fish inlet 121 of the second fish suction tank 120 to reduce the volume of the vacuum assembly 200 and improve the suction efficiency of the first vacuum pump 210 and the inflation efficiency of the second vacuum pump 220.

[0050] See Figure 1 and Figure 2 In this embodiment, the vacuum assembly 200 may further include a first connecting tube 240 and a second connecting tube 250. One end of the first connecting tube 240 is connected to the first fish suction tank 110, and the other end of the first connecting tube 240 is connected to the first vacuum pump 210 or the second vacuum pump 220 via a connector 230. One end of the second connecting tube 250 is connected to the second fish suction tank 120, and the other end of the second connecting tube 250 is connected to the first vacuum pump 210 or the second vacuum pump 220 via a connector 230.

[0051] One end of the first connecting pipe 240 communicating with the first fish suction tank 110 is located at the top of the first fish suction tank 110, and one end of the second connecting pipe 250 communicating with the second fish suction tank 120 is located at the top of the second fish suction tank 120. This improves the space utilization of the first fish suction tank 110 and the second fish suction tank 120, allowing the first fish suction tank 110 and the second fish suction tank 120 to fully accommodate fish and water, thereby increasing the total amount of fish and water that can be caught in a single catch, thereby improving the single fish suction and fish discharge efficiency of the vacuum fish suction device.

[0052] In some embodiments, one end of the first connecting pipe 240 connected to the first fish suction tank 110 is located above the first fish inlet 111, and one end of the second connecting pipe 250 connected to the second fish suction tank 120 is located above the second fish inlet 121, thereby facilitating the suction and accommodation of fish and water.

[0053] In some embodiments, the vacuum assembly 200 may further include a third connecting pipe 260 and a fourth connecting pipe 270. One end of the third connecting pipe 260 is connected to the first vacuum pump 210, and the other end of the third connecting pipe 260 is connected to the connecting port of the connector 230. One end of the fourth connecting pipe 270 is connected to the second vacuum pump 220, and the other end of the fourth connecting pipe 270 is connected to the connecting port of the connector 230.

[0054] In other embodiments, the vacuum assembly 200 may further include an air compressor 280. The air compressor 280 may be in communication with the connector 230 to provide power for switching the connector 230, thereby enabling the first vacuum pump 210 to be in communication with the first fish suction tank 110 or the second fish suction tank 120 via the connector 230, and the second vacuum pump 220 to be in communication with the first fish suction tank 110 or the second fish suction tank 120 via the connector 230.

[0055] See Figure 1 and Figure 2 In this embodiment, the vacuum fish suction device may further include a fish suction tube 310, the input end of the fish suction tube 310 is used to connect to the breeding pond, and the output end of the fish suction tube 310 is connected to the first fish inlet 111 and the second fish inlet 121 respectively.

[0056] The fish suction pipe 310 comprises a first tube 311, a second tube 312, and a third tube 313. The input end of the first tube 311 is connected to the aquaculture pond, while the output end of the first tube 311 is connected to the input ends of the second tube 312 and the input ends of the third tube 313, respectively. The output end of the second tube 312 is connected to the first fish inlet 111 of the first fish suction tank 110. The output end of the third tube 313 is connected to the second fish inlet 121 of the second fish suction tank 120. This allows the first tube 311 to transfer fish and water from the aquaculture pond to the first and second fish suction tanks 110, 120, respectively. This allows for a circular fish suction and discharge process between the first and second fish suction tanks 110, 120, and improves the efficiency of catching and transporting fish.

[0057] In some embodiments, the caliber of the output end of the second tube 312 is smaller than the caliber of the first fish inlet 111, and the caliber of the output end of the third tube 313 is equal to the caliber of the second fish inlet 121. This prevents the inner walls of the first fish inlet 111 and the second fish inlet 121 from scratching the fish when the fish pass through the first fish inlet 111 and the second fish inlet 121, thereby ensuring that the fish safely enter the first fish suction tank 110 and the second fish suction tank 120, thereby improving the survival efficiency of the fish.

[0058] See Figure 1 and Figure 2 In this embodiment, the vacuum fish suction device may further include a fish discharge pipe 320. The fish discharge pipe 320 may be connected to the first fish discharge port 112 and the second fish discharge port 122, respectively, to discharge the fish in the first chamber and the second chamber.

[0059] The fish suction pipe 310 includes a fourth tube 321, a fifth tube 322, and a sixth tube 323. The input end of the fourth tube 321 is connected to the first fish discharge port 112 of the first fish suction tank 110. The input end of the fifth tube 322 is connected to the second fish discharge port 122 of the second fish suction tank 120. The input end of the sixth tube 323 is connected to the output ends of the fifth tube 322 and the sixth tube 323, respectively. The output end of the sixth tube 323 is used to discharge fish, thereby achieving a circular fish suction and discharge cycle between the first and second fish suction tanks 110, 120, and improving the efficiency of catching and transporting fish.

[0060] In some embodiments, the caliber of the input end of the fourth tube 321 is larger than the caliber of the first row of fish ports 112, and the caliber of the input end of the fifth tube 322 is larger than the caliber of the second row of fish ports 122. This prevents the inner walls of the fourth tube 321 and the fifth tube 322 from scratching the fish when they pass through the first and second rows of fish ports 112, 122, thereby ensuring that the fish are safely discharged from the first and second fish suction tanks 110, 120, and improving the survival efficiency of the fish.

[0061] See Figure 1 and Figure 2 In this embodiment, the vacuum fish suction device may further include a mobile platform 700. The first fish suction tank 110, the second fish suction tank 120, the vacuum assembly 200, and the fish discharge pipe 320 may all be disposed on the mobile platform 700 so as to be able to move horizontally with the mobile platform 700. This facilitates the movement of the vacuum fish suction device between various aquaculture ponds and facilitates the flexible placement of the vacuum fish suction device, thereby improving the efficiency of catching and transporting fish, thereby enhancing the efficiency of fish aquaculture.

[0062] In some embodiments, the mobile platform 700 may be a flatbed truck, a truck, or the like.

[0063] See Figure 1 In this embodiment, the vacuum fish suction device may further include a lifting frame 800. The lifting frame 800 is disposed on the mobile platform 700 so as to be escalable. The first fish suction tank 110, the second fish suction tank 120, the vacuum assembly 200, and the fish discharge tube 320 are all disposed on the lifting frame 800 so as to be able to rise and fall with the lifting frame 800. The fish suction tube 310 is also disposed on the lifting frame 800 so as to be able to rise and fall with the lifting frame 800.

[0064] When the aquaculture pond is a aquaculture barrel or aquaculture box, due to the different heights of the aquaculture pond, the heights of the first fish suction tank 110, the second fish suction tank 120, the vacuum assembly 200, the fish suction pipe 310 and the fish discharge pipe 320 can be adjusted by adjusting the lifting frame 800, thereby facilitating the suction of fish and improving the efficiency of fish catching and transporting.

[0065] In some embodiments, the lifting frame 800 may be provided with a lifting motor (not shown in the figure), which can be in transmission connection with the lifting frame 800 to achieve relative lifting between the lifting frame 800 and the mobile platform 700.

[0066] See Figure 1 In this embodiment, the vacuum fish suction device may further include a drain assembly 400. The drain assembly 400 is connected to the output end of the fish drain pipe 320 for separating fish from water.

[0067] Drain assembly 400 may include a drain pipe 410. The input end of drain pipe 410 is connected to fish drain pipe 320. Drain pipe 410 is tilted, with the output end of drain pipe 410 located below the input end. Drain pipe 410 has multiple diversion ports (not shown) spaced along the bottom of drain pipe 410. These diversion ports are used to divert and drain water, while the output end of drain pipe 410 is used to discharge fish.

[0068] When the fish and water in the first and second fish suction tanks 110 and 120 enter the drain pipe 410 through the fish discharge pipe 320, the fish and water enter the drain pipe 410 through the input end of the drain pipe 410 and flow downward along the drain pipe 410. As the fish and water flow in the drain pipe 410, the water leaves the drain pipe 410 through the diversion port of the drain pipe 410, and the fish are discharged from the output end of the drain pipe 410, thereby separating the fish and water, facilitating subsequent grading, tank transfer, stocking, or slaughter of the fish.

[0069] In some embodiments, a drain observation hand hole 411 is provided on the drain pipe 410 to facilitate staff to observe the status inside the drain pipe 410.

[0070] In some embodiments, the drain pipe 410 can also be a drain slide, and a diversion port is opened at the bottom of the drain slide to allow fish and water to flow downward from the input end of the drain slide, thereby achieving the separation of fish and water.

[0071] In some embodiments, the drain assembly 400 may further include a drain collection cover 420. The drain collection cover 420 is disposed on the lower side of the drain pipe 410, and the input end of the drain collection cover 420 is connected to the outer peripheral wall of the drain pipe 410, so that the drain collection cover 420 is in communication with the multiple diversion ports. The water diverted from the multiple diversion ports enters the drain collection cover 420 through the input end of the drain collection cover 420 and is discharged to the outside through the output end of the drain collection cover 420, so as to facilitate the centralized treatment of the water flow, thereby facilitating water changes in the aquaculture pond.

[0072] In other embodiments, the input end of the drain collection hood 420 is conical, and the cross-street area of ​​the input end of the drain collection hood 420 gradually decreases in the direction toward the output end of the drain collection hood 420, so that the drain collection hood 420 can fully receive the water discharged from multiple diversion ports.

[0073] In other embodiments, a drain inspection door 421 is provided on the input end of the drain collection cover 420 to facilitate staff to enter the drain assembly 400 through the drain inspection door 421 for inspection and maintenance.

[0075] In some embodiments, the drain assembly 400 may further include a drain pipe 430. The drain pipe 430 is connected to the drain collection cover 420 to drain the water in the drain collection cover 420 to the outside.

[0076] See Figure 1 In this embodiment, the vacuum fish suction device may further include a weighing assembly 500. The weighing assembly 500 is connected to the output end of the drain pipe 410 and is used to weigh the fish. After the weighing assembly 500 weighs the fish, subsequent grading, pond transfer, stocking, or slaughter of the fish is improved.

[0077] In some embodiments, the weighing assembly 500 may include a conveying platform 510, a transmission motor 520, and a weight sensor 530. The conveying platform 510 is disposed on the lifting frame 800 so as to be able to rise and fall with the lifting frame 800. The input end of the conveying platform 510 is located on the lower side of the drain pipe 410 so as to be able to receive the fish output by the drain pipe 410. The transmission motor 520 is disposed on the conveying platform 510 and is in transmission connection with the transmission platform so as to drive the transmission motor 520 to transmit. The weight sensor 530 is disposed on the conveying platform 510 so as to be able to detect the weight of the fish on the conveying platform 510.

[0078] In some embodiments, the conveying platform 510 may be a conveyor belt.

[0079] In other embodiments, the weighing assembly 500 may further include a weighing output tube 540. The input end of the weighing output tube 540 may be connected to the output end of the conveying platform 510 to receive and output the fish outputted by the transmission platform.

[0080] In other embodiments, the weighing output tube 540 may also be disposed on the lifting frame 800 so as to be able to rise and fall along with the lifting frame 800 .

[0081] See Figure 1In this embodiment, the vacuum fish suction device may further include a control component 600. The control component 600 can be electrically connected to the first vacuum pump 210, the second vacuum pump 220, and the connector 230 to control the start and stop of the first vacuum pump 210, the second vacuum pump 220, and the pipeline switching of the connector 230.

[0082] In some embodiments, the control component 600 can also be electrically connected to the valves of the fish tank to control the opening and closing of the first fish inlet 111 , the first row of fish inlets 112 , the second fish inlet 121 and the second row of fish inlets 122 .

[0083] In some embodiments, the control assembly 600 can also be electrically connected to the liquid level sensor 130 to respectively obtain liquid level parameters in the first fish suction tank 110 and the second fish suction tank 120. The control assembly 600 can also be electrically connected to the pressure sensor 140 to respectively obtain pressure parameters in the first fish suction tank 110 and the second fish suction tank 120.

[0084] In some embodiments, the control assembly 600 is electrically connected to the air compressor 280 so as to be able to control the state switching of the connecting member 230 through the air compressor 280 .

[0085] In other embodiments, the control component 600 may further include a display screen to display the status of the first fish suction tank 110, the second fish suction tank 120, the first vacuum pump 210, the second vacuum pump 220, the weighing component 500 or the lifting component.

[0086] See Figure 1 and Figure 2 In the present invention, when the vacuum fish suction device is in use, the vacuum fish suction device is moved to the breeding pond, and then the lifting frame 800 is adjusted so that the input end of the fish suction tube 310 extends into the breeding pond.

[0087] After the input end of the fish suction tank is extended into the aquaculture pond, the first fish inlet 111 and the second fish outlet 122 are opened, the first fish outlet 112 and the second fish inlet 121 are closed, and the first vacuum pump 210 and the second vacuum pump 220 are activated, thereby placing the first chamber at a negative pressure and the second chamber at a high pressure. The first fish suction tank 110 draws in and holds fish and water through the fish suction tube 310.

[0088] When the liquid level in the first fish suction tank 110 rises to a preset high liquid level, the liquid level sensor 130 in the first fish suction tank 110 sends a signal to the control assembly 600. The control assembly 600 controls the first fish inlet 111 and the second fish outlet 122 to close, the first fish outlet 112 and the second fish inlet 121 to open, and the connector 230 to switch, so that the first fish suction tank 110 is connected to the second vacuum pump 220, and the second fish suction tank 120 is connected to the first vacuum pump 210.

[0089] After the second vacuum pump 220 pumps high-pressure gas into the first fish suction tank 110, the first fish suction tank 110 is in a high-pressure state. Under the action of the high-pressure gas, the fish and water in the first fish suction tank 110 are quickly discharged through the fish discharge pipe 320 into the drain pipe 410. The drain pipe 410 receives the fish and water discharged from the fish discharge pipe 320, separates the fish and water, and then outputs the fish through the drain pipe 410 to the weighing assembly 500, thereby facilitating the weighing of the fish.

[0090] After the first vacuum pump 210 absorbs the gas in the second fish suction tank 120 , the second fish suction tank 120 is in a negative pressure state, so that the fish in the breeding pond enter the second fish suction tank 120 through the fish suction pipe 310 .

[0091] When the liquid level in the second fish suction tank 120 rises to the preset high liquid level position, the liquid level sensor 130 of the second fish suction tank 120 triggers the control component 600, and the control component 600 controls the first fish inlet 111 and the second fish outlet 122 to open, and the first fish outlet 112 and the second fish inlet 121 to close, and the connecting piece 230 is switched to connect the first vacuum pump 210 with the first fish suction tank 110 and the second vacuum pump 220 with the second fish suction tank 120, so that the first fish suction tank 110 sucks fish, and the second fish suction tank 120 discharges fish and water into the drain component 400 through the fish discharge pipe 320.

[0092] The first fish suction tank 110 and the second fish suction tank 120 cyclically suck and discharge fish, thereby effectively reducing the working time of the vacuum fish suction device, improving the efficiency of fish catching, transporting, grading, and stocking. In addition, the vacuum fish suction device can also reduce damage to fish during the catching and transporting process, and improve the survival efficiency of fish.
