[0002] With the development and progress of aquaculture, mechanization of aquaculture equipment has become a trend of the times. Traditional manual fishing methods are inefficient, fishermen work in a harsh environment and have high labor intensity. Existing equipment can hardly meet the needs of modern aquaculture.

[0003] Currently, mechanized fishing methods are being used more and more. However, during fishing operations, fish often experience stress reactions, which can cause collisions between fish and lead to the death or appearance damage of fish.

Generally, a water ring vacuum pump is used as the power source. In the process of realizing the vacuum tank vacuuming and pressurization, there are mainly two ways of switching: one is to convert through two three-way pneumatic valves, and the other is to add an electromagnetic guide pneumatic valve or pneumatic cylinder to the pipeline to realize the opening and closing of the valve, but this method will cause the electromagnetic guide pneumatic valve or pneumatic cylinder to be immersed in water for a long time, and there is a risk of damage and leakage of the seal; in addition, whether it is a three-way pneumatic valve or an electromagnetic guide pneumatic valve, an additional air compressor is required as the power source of the control valve, which makes the overall structure of the vacuum fish suction pump large and complex, and the conversion structure is complex, which is not conducive to later inspection and maintenance.

[0030] 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.

[0031] See also Figure 1-6 The present invention provides a technical solution: a vacuum fish suction pump system for aquaculture fishing, comprising a vacuum tank 1 and a water ring vacuum pump 2 for pumping negative pressure and pressurizing the vacuum tank 1, the vacuum tank 1 is provided with a connected fish suction pipe 4, an electrode stunner 8 is provided in the fish suction pipe 4, the electrode stunner 8 comprises electrode plates respectively installed in the fish suction pipe 4, the electrode plates comprise a positive electrode 42 and a negative electrode 43, the positive electrode 42 and the negative electrode 43 are both arc plates, and are respectively arranged on the inner wall of the fish suction pipe 4, by respectively arranging the positive electrode 42 and the negative electrode 43 on the inner wall of the fish suction pipe 4, when the fish-water mixture enters the fish suction pipe 4, the positive electrode 42 and the negative electrode 43 are respectively arranged on the inner wall of the fish suction pipe 4, A closed current loop is formed between the positive electrode 42 and the negative electrode 43. When the fish passes through this current loop, the current will flow through the fish's body, thereby affecting its brain and nervous system, especially affecting the activity of its neurons, so that the fish quickly loses consciousness and falls into a coma, thereby avoiding stress reactions in the fish during fishing operations, thereby avoiding collisions between the fish and causing casualties of the fish. The electrode stunner 8 also includes a control unit, which is mainly used to adjust the intensity and time of the current to adapt to fish of different sizes and types. The voltage of the electrode stunner 8 in the fish suction pipe 4 is calculated as follows:

[0032] The resistivity of seawater is known to be s is 0.3~0.5Ω·m, the electrical conductivity of fish meat is σ f The average is 1100μS / cm, the current I0 for stunning fish is about 0.1A, the safe current for human body is 10mA, and the diameter of the part of the fish suction pipe where the electrode stunner is installed is 200mm.

[0033] Fish flesh resistivity ρ f for:

[0034]

[0035] The length of the electrode plate is 1m. During the vacuum capture process, the fish almost fills the pipe. Therefore, the resistance R of the electrode stunner 8 installed in the fish suction pipe 4 is d Can be regarded as the resistance of fish meat:

[0036]

[0037] Among them, l d is the length of the electrode plate; S is the cross-sectional area of ​​the portion of the electrode stunner 8 installed in the fish suction pipe 4.

[0038] Therefore, the voltage ΔU that needs to be applied in the vertigo tube section is:

[0039] ΔU=I0R d =0.1×289.49=28.949V

[0040] Calculation of safe distance of electrode stunner

[0041] In order to ensure the safety of the workers, it is necessary to calculate the safe distance between the two ends of the fish suction pipe 4 and the electrode stunner 8 during operation. It is assumed that when the current drops to 10mA, it is considered a safe area. Therefore, according to the voltage drop formula, the safe distance l s It can be calculated as a system of equations:

[0042]

[0043] Solving the equations gives: l s =3.84m

[0044] Among them, ρ s is the resistivity of seawater, taking the maximum value of 0.5Ω·m; P is the power of the safe distance pipe section; R s Is is the resistance of the safe distance pipe section; Is is the current of the safe distance pipe section, so when the fish is stun-sucking operation, the distance between both ends of the fish-sucking pipeline 4 and the electrode stunner is more than 3.84m, which belongs to the human safety range.

[0045] A fish inlet 40 is provided at one end of the fish suction pipe 4, and the fish inlet 40 is in a trumpet shape. By setting the fish inlet 40 in a trumpet shape, when the fish suction pipe 4 starts to absorb the fish catch, the trumpet-shaped fish inlet 40 can guide the fish catch, thereby preventing the fish catch from being blocked in the fish inlet 40 and causing damage. A fish inlet valve 41 is provided at the other end of the fish suction pipe 4. Since the end of the fish suction pipe 4 provided with the fish inlet valve 41 extends into the vacuum tank 1, the fish inlet valve 41 is located in the vacuum tank 1, and the fish inlet valve 41 is rotatably connected to the fish suction pipe 4, and the diameter of the fish inlet valve 41 is larger than the diameter of the fish suction pipe 4. Therefore, when the fish is not sucked, the fish inlet valve 41 swings down and rests on the end of the fish suction pipe 4 due to its own gravity, thereby extending to the inside of the vacuum tank 1. The fish suction pipe 4 at this end is blocked and closed, and the fish suction pipe 4 is also provided with a fish inlet buffer sheet at the end corresponding to the fish inlet valve 41. By providing the fish inlet buffer sheet, when the fish suction pipe 4 absorbs the fish and then discharges it into the vacuum tank 1 from the end of the fish inlet valve 41, the fish inlet buffer sheet can buffer the fish discharged from the fish suction pipe 4, thereby preventing the fish from directly falling into the vacuum tank 1 and causing collision damage. A fish outlet pipe 7 connected to the vacuum tank 1 is also provided on the other side of the vacuum tank 1. One end of the fish outlet pipe 7 is connected to the vacuum tank 1, and the other end is provided with a fish outlet valve 70. The fish outlet valve 70 also rotates with one end of the fish outlet pipe 7. The structure of the fish outlet valve 70 is the same as that of the fish inlet valve 41. When no fish is discharged, it also relies on its own gravity to swing down and press against the end of the fish outlet pipe 7, thereby blocking and closing the fish outlet pipe 7.

[0046] A four-way valve 3 connected to each other is provided between the water ring vacuum pump 2 and the vacuum tank 1. The four-way valve 3 is respectively provided with a first connection port 30 and a second connection port 31. The first connection port 30 is connected to the vacuum tank 1, and the second connection port 31 is connected to the outside air. When the water ring vacuum pump 2 is in a negative pressure state, the air intake port 20 is connected to the first connection port 30, and the air exhaust port 21 is connected to the second connection port 31. When the water ring vacuum pump 2 is in a pressurized state, the air intake port 20 is connected to the second connection port 31, and the air exhaust port 21 is connected to the first connection port 30. A motor 22 and a reducer 23 drivingly connected to the motor 22 are also provided on the water ring vacuum pump 2. A rotatably connected valve core 32 is provided inside the four-way valve 3. The valve core 32 is fixedly connected to the driving end of the reducer 23. When fishing starts When fishing, it is necessary to adjust the vacuum tank 1 to a vacuum state, so that a pressure difference will be formed between the vacuum tank 1 and the external air pressure, so that the fish is sucked into the vacuum tank 1 from the fish suction pipe 4 due to the pressure difference. Therefore, at this time, the motor 22 controls the reducer 23 to start, and the reducer 23 drives the valve core 32 to rotate, so that the air intake port 20 of the water ring vacuum pump 2 is connected with the first connecting port 30 of the four-way valve 3, and the exhaust port 21 of the water ring vacuum pump 2 is connected with the second connecting port 31. At this time, the water ring vacuum pump 2 is started. Since the first connecting port 30 is connected with the inside of the vacuum tank 1, the air in the vacuum tank 1 is sucked out from the air intake port 20 through the first connecting port 30. Since the air intake port 20 and the exhaust port 21 are interconnected, and the water ring vacuum pump 2 can only be unidirectional Air, so the air in the vacuum tank 1 is sucked out from the air intake port 20 through the first connecting port 30, and then discharged from the exhaust port 21, and finally discharged into the air through the second connecting port 31. At this time, the vacuum tank 1 is in a negative pressure state. Since the pressure in the vacuum tank 1 is too low at this time, and one end of the fish outlet pipe 7 with a fish outlet valve 70 is outside the vacuum tank 1, at this time, due to the pressure difference between the outside air and the inside of the vacuum tank 1, the fish outlet valve 70 will be pressed on the fish outlet pipe 7 due to the outside pressure and its own gravity, thereby the fish outlet pipe 7 is always blocked and closed, and the fish inlet valve 41 on the fish suction pipe 4 is in the vacuum tank 1. At this time, due to the low pressure in the vacuum tank 1, the outside pressure is greater than the pressure in the vacuum tank 1, and the fish suction pipe 4 is used to connect the vacuum tank 1 with the outside water surface and Atmospheric pressure is connected. When the external pressure is greater than the pressure in the vacuum tank 1, the fish and water mixture will enter the fish suction pipe 4 from the fish inlet 40. The fish inlet valve 41 will automatically open under the push of the fish and water, and the fish and water mixture will fall onto the fish inlet buffer sheet, and then fall into the vacuum tank 1, thereby completing the fish suction process during fishing. A liquid level detection sensor 6 is also provided on the vacuum tank 1. As the fish and water mixture in the vacuum tank 1 increases, when it reaches a certain height, the liquid level detection sensor 6 installed on the upper side of the vacuum tank 1 detects the liquid level height and sends a signal to the control box. At this time, the control box sends a command to the motor 22, thereby controlling the reducer 23 to rotate the valve core 32, thereby changing the vacuum state in the vacuum tank 1 into a pressurized state.When it becomes a pressurized state, the air intake port 20 of the water ring vacuum pump 2 is communicated with the second connecting port 31, and the air exhaust port 21 is communicated with the first connecting port 30. Therefore, the air intake port 20 sucks in external air through the second connecting port 31 and then discharges it through the exhaust port 21. The air discharged from the exhaust port 21 is then discharged into the vacuum tank 1 through the first connecting port 30, thereby realizing the pressurization process in the vacuum tank 1. When the vacuum tank 1 is in the pressurization process, the pressure in the vacuum tank 1 increases, and the fish suction pipe 4 stops sucking fish and water. When the pressure in the vacuum tank 1 is greater than the external air pressure, the fish inlet valve 41 will be squeezed and blocked on the fish suction pipe 4 because the pressure in the vacuum tank 1 is greater than the external air pressure. , thereby blocking the fish suction pipe 4, and the fish outlet valve 70 will automatically open due to the pressure in the vacuum tank 1 and the pressure of the fish-water mixture, and then the fish-water mixture in the vacuum tank 1 will be discharged from the fish outlet pipe 7, thereby completing the fish outlet process during the fishing process. By only providing a four-way valve 3 between the vacuum tank 1 and the water ring vacuum pump 2, it is only necessary to adjust the rotation of the valve core 32 in the four-way valve 3 to realize the negative pressure or pressurization switching in the vacuum tank 1, thereby realizing the fishing and discharge process of the catch, and it can also greatly reduce the overall structure of the entire vacuum fish suction system, and using the four-way valve 3 as a conversion structure also greatly simplifies the structure, which is more conducive to later inspection and maintenance. ,

[0047] Because the fish-water mixture is first absorbed into the vacuum tank 1, various sludge, fish scales or other impurities will remain on the inner wall of the vacuum tank 1 after the vacuum tank 1 is used. If it is not cleaned for a long time, various bacteria will breed. Therefore, a cleaning component 5 is also provided in the vacuum tank 1. The cleaning component 5 includes a water inlet pipe 50 extending into the vacuum tank 1 and a rotating nozzle 51 rotatably connected to one end of the water inlet pipe 50. A plurality of water spray ports 52 are provided on the rotating nozzle 51. The water spray ports 52 are embedded in the rotating nozzle 51 to avoid sharp corners of the rotating nozzle 51, which may cause damage to the fish. The water outlet of the water spray port 52 The directions are different, and the spray surface of the water spray port 52 can reach within a range of 40°, and the rotating nozzle 51 can rotate 360° around the water inlet pipe 50. The other end of the water inlet pipe 50 is connected to a cleaning water pump 9. When the vacuum tank 1 needs to be cleaned, the cleaning water pump 9 is used to pump water into the water inlet pipe 50, and then sprayed from the rotating nozzle 51. When the water pressure is too high, the rotating nozzle 51 will rotate around the water inlet pipe 50 autonomously, so that the water sprayed from the water spray port 52 can fully clean the side wall of the vacuum tank 1 to ensure the cleanliness and hygiene of the vacuum tank 1 and avoid the growth of bacteria. In addition, the rotating nozzle 51 can be flexibly configured and arranged according to the size of the tank body, and is suitable for tank bodies of various capacities.

[0048] The beneficial effects of the present invention are as follows: by providing an electrode stunner 8 in the fish suction pipe 4, when fishing, the electrode stunner 8 can stun the fish for a short time, thereby avoiding the stress reaction of the fish and causing casualties, and in order to ensure the safety of the staff during operation, the system will automatically calculate the safe distance between the two ends of the fish suction pipe 4 and the electrode stunner 8 before the operation, thereby ensuring the safety of the staff during operation, and a four-way valve 3 is provided between the water ring vacuum pump 2 and the vacuum tank 1. During operation, only the switching of the four-way valve 3 needs to be controlled to realize the switching between the negative pressure and the pressurization in the vacuum tank 1 to realize the fishing and discharge of the fish, thereby greatly reducing the overall structure of the vacuum fish suction pump system, and the conversion structure is also simplified to facilitate the later inspection and maintenance, and a cleaning component 5 is also provided in the vacuum tank 1. By providing the cleaning component 5, when the fish is caught, the cleaning component 5 can clean the inner wall of the vacuum tank to ensure the cleanliness and hygiene in the vacuum tank and avoid the growth of bacteria.
