Description

[0002] With the development of my country's deep-sea aquaculture industry, the scale of deep-sea aquaculture is increasing, and submersible aquaculture cages with typhoon resistance are gradually being used. To ensure that these submersible aquaculture cages have excellent wind and wave resistance, the deck space above the water surface is relatively limited. The deck space is usually only used to place facilities such as control systems and generator sets. However, since existing feeders need to be installed above the water surface to provide a liquid level difference between the feed system and the aquaculture water surface, thereby preventing water from entering the feed storage bin, if the existing feeders are directly used in fully submerged underwater conditions, there is a risk of seawater backflowing into the feed storage bin, resulting in the waste of feed. Therefore, existing feeders are prone to seawater backflow and feed waste when operating underwater. Summary of the Invention

[0038] The technical solution of the present invention utilizes a storage bin to pre-store bait, and the bait enters a premixing tank through a feeding pipeline, wherein the premixing tank is connected to an external water area through a water supply pipeline. Since the bait throwing machine is used to throw bait underwater, when the third valve body of the self-input pipeline of the water supply system is in an open state, due to the liquid level difference between the premixing tank and the external water area, the water in the external water area naturally flows into the premixing tank. After the bait and the water are mixed in the premixing tank, the second valve body of the discharge assembly is opened, and the first pump body is used to suck the material-water mixture out of the premixing tank and output it to the feeding port to realize feeding. When the machine is in normal use, the amount of water entering the premixing tank is balanced with the amount of water output, so there will be no backflow of external water. The liquid level detection component is used to detect whether the water level in the premixing tank exceeds the preset maximum water level. When the water level in the premixing tank exceeds the preset maximum water level, the liquid level detection component closes the first valve body and the second valve body to prevent the external water from continuing to enter the premixing tank, which would cause the water level to be too high and backflow into the storage bin. At the same time, the first pump body is used to pump and drain the premixing tank. When the water level in the premixing tank is lower than the preset standard water level, the feeding machine can resume feeding. This feeding machine can prevent water from external waters from backflowing into the storage bin, which can reduce the risk of feed being scrapped in the feeding machine. In addition, there is space in the premixing tank to temporarily store water, which provides time for the emergency shutdown of the first valve body, further reducing the risk of water backflowing into the storage bin.

[0051] The invention provides a bait throwing machine.

[0052] Reference Figure 1 In one embodiment of the present invention, the bait feeding machine is used to feed bait underwater, including a storage bin 1, a plurality of feeding systems 2, a water supply system 3 and a plurality of liquid level detection components 6, the feeding system 2 includes a feeding pipeline 21 and a discharging pipeline 22, the feeding pipeline 21 includes a premixing tank 211 and a first valve body 212, the premixing tank 211 is connected to the storage bin 1, and the first valve body 212 is provided at the connection between the storage bin 1 and the premixing tank 211; the discharging pipeline 22 includes a first pump body 221 and a second valve body 222, a first end of the first pump body 221 is connected to the premixing tank 211, a second end of the first pump body 221 is connected to one end of the second valve body 222, and a second end of the second valve body 222 is connected to the first end of the first pump body 221. The end is used to be connected to the feeding port; the water supply system 3 includes a self-input pipeline 31 provided with a third valve body 311, the first ends of the third valve bodies 311 are respectively connected to the premixing tanks 211 of different feeding systems 2, and the second ends of the third valve bodies 311 are used to be connected to the external water area 4; the liquid level detection component 6 is provided on the inner wall of the premixing tank 211, and the liquid level detection component 6 is electrically connected to the first pump body 221, the first valve body 212, the second valve body 222 and the third valve body 311. The liquid level detection component 6 is used to detect whether the water level in the premixing tank 211 is within a preset range, so as to control the switch of the first pump body 221, the first valve body 212, the second valve body 222 and the third valve body 311.

[0053] By using the storage bin 1 to pre-store bait, the bait enters the premixing tank 211 through the feeding pipe 21, wherein the premixing tank 211 is connected to the external water area 4 through the water supply pipe. Since the bait feeding machine is used for underwater bait feeding, when the third valve body 311 of the self-input pipe 31 of the water supply system 3 is in an open state, due to the liquid level difference between the premixing tank 211 and the external water area 4, the water in the external water area 4 naturally flows into the premixing tank 211. After the bait and the water are mixed in the premixing tank 211, the second valve body 222 of the discharge assembly is opened, and the first pump body 221 is used to suck the material-water mixture from the premixing tank 211 and output it to the feeding port to achieve feeding. When the bait machine is in normal use, the amount of water entering the premixing tank 211 is balanced with the amount of water output, so there will be no backflow of external water. The liquid level detection component 6 is used to detect whether the water level in the premixing tank 211 exceeds the preset maximum water level. When the water level in the premixing tank 211 exceeds the preset maximum water level, the liquid level detection component 6 closes the first valve body 212 and the second valve body 222 to prevent the external water from continuing to enter the premixing tank 211, which would cause the water level to be too high and backflow into the storage bin 1. At the same time, the first pump body 221 is used to pump and drain the premixing tank 211. When the water level in the premixing tank 211 is lower than the preset standard water level, the bait machine can resume feeding. The bait machine can prevent the water in the external water area 4 from backflowing into the storage bin 1, which can reduce the risk of the feed being scrapped by the bait machine. In addition, there is space in the premixing tank 211 to temporarily store water, which provides time for the emergency shutdown of the first valve body 212, further reducing the risk of water backflowing into the storage bin 1.

[0054] Optionally, the water supply system 3 also includes a pumping pipeline 32, the pumping pipeline 32 includes a fourth valve body 321, a second pump body 322 and a fifth valve body 323, the first end of the fourth valve body 321 is used to connect to the external water area 4, the second end of the fourth valve body 321 is connected to the first end of the second pump body 322, the second end of the second pump body 322 is connected to the first end of a different fifth valve body 323, the second end of a fifth valve body 323 is connected to the third end of the first pump body 221 of a feeding system 2, and the fourth valve body 321, the second pump body 322 and the fifth valve body 323 are all electrically connected to the liquid level detection component 6.

[0055] The second pump body 322 is connected to the external water area 4 via the fifth valve body 323. The second pump body 322 pumps water from the external water area 4 into the first pump body 221, providing the first pump body 221 with working water with impact pressure. When the first pump body 221 pumps the feed-water mixture to the feeding port, the working water impacts the feed-water mixture, thereby expanding the bait delivery range. By adding the fourth valve body 321, when a single feeding system 2 needs to be suspended, the corresponding fourth valve body 321 can be closed to prevent water from being input into the suspended feeding system 2 without affecting the normal operation of other feeding systems 2.

[0056] The present invention also proposes a control method for a bait throwing machine, referring to Figure 1 and Figure 2 , including the following steps:

[0057] Step S100: Open the first control valve to allow the bait in the storage bin 1 to be fed into the premixing tank 211;

[0058] Step S200: utilizing the liquid level difference between the premixing tank 211 and the external water area 4, the water in the external water area 4 is input into the premixing tank 211 to mix with the bait, thereby forming a bait-water mixture;

[0059] Step S300: outputting the material-water mixture to the feeding port;

[0060] Step S400: using the liquid level detection component 6 to detect whether the water level in the premix tank 211 exceeds a preset minimum level;

[0061] Step S500: If the water level in the premixing tank 211 exceeds the preset minimum water level, the liquid level detection component 6 controls the third valve body 311 to close, preventing water from continuing to be input into the premixing tank 211;

[0062] Step S600: using the discharge pipe 22 to pump water out of the premixing tank 211;

[0063] Step S700: until the water level in the premixing tank 211 is lower than the preset minimum water level, the bait feeding machine can resume the feeding operation.

[0064] When the feeding system 2 is blocked, the first pump body 221 cannot pump out the feed-water mixture in the premixing tank 211. At the same time, the water input by the pumping pipe 32 cannot be discharged through the first pump body 221 and may flow back into the premixing tank 211, causing the water level in the premixing tank 211 to rise sharply. When the liquid level detection component 6 detects that the water level in the premixing tank 211 reaches or exceeds the preset minimum water level, it indicates that a blockage has occurred inside the feeding system 2. The third valve body 311 can be closed immediately to reduce the amount of bait and water input to the premixing tank 211. The pumping pipe 32 can then be used to continue to pump pressurized driving water to impact the discharge pipe 22. If the water level in the premixing tank 211 drops, it means that the blocked part of the pipe has been flushed away by the driving water, and the third valve can be opened to resume the feeding operation.

[0065] Optionally, refer to Figures 1 to 3 After the step S600 of using the discharge pipe 22 to pump out the water from the premixing tank 211, the following steps are also included:

[0066] Step S800: using the pumping line 32 to pump driving water with water pressure into the discharge line 22 to impact and clear it.

[0067] Optionally, refer to Figures 1 to 4 After step S800 of pumping a large amount of driving water into the pumping pipe 32 to impact and clear the discharge pipe 22, the following steps are also included:

[0068] Step S900: Detecting whether the water level in the premixing tank 211 exceeds a preset middle water level;

[0069] Step S1000: If the water level in the premixing tank 211 exceeds the preset middle water level, the first valve body 212 is closed; and driving water with water pressure is pumped into the pumping line 32 to continuously impact and clear the discharge line 22 .

[0070] If the third valve body 311 is closed and the driving water is used to impact the discharge pipeline 22, the liquid level detection component 6 detects that the water level in the premixing tank 211 reaches or exceeds the preset middle water level, which means that it is difficult to improve the blockage by only driving water impact in a short time, and the first valve body 212 needs to be closed to prevent the water in the premixing tank 211 from flowing back into the storage bin 1. If the water level drops to the preset minimum water level again, it means that the pipeline blockage is completely improved and the feeding operation can be resumed.

[0071] Optionally, refer to Figures 1 to 5 If the water level in the premixing tank 211 exceeds the preset middle water level, the first valve body 212 is closed; after step S1000 of continuously impacting and unblocking the discharge pipeline 22 by pumping driving water with water pressure through the pumping pipeline 32, the following steps are also included:

[0072] Step S1100: Detecting whether the water level in the premix tank 211 exceeds a preset maximum water level;

[0073] Step S1200: If the water level in the premixing tank 211 exceeds the preset middle water level, the first pump body 221 and the fifth valve body 323 are closed;

[0074] Step S1300: manually dismantling the feeding system 2 and manually clearing the blockage.

[0075] If the third valve body 311 is closed and the driving water is used to impact the discharge pipe 22, the liquid level detection component 6 detects that the water level in the corresponding mixing tank reaches or exceeds the preset maximum water level, which means that it is difficult to solve the blockage problem by relying on the driving water provided by the second pump body 322 and the pressurized jet flushing of the first pump body 221. There is also a risk of driving water backflowing into the storage bin 1. Therefore, the fifth valve body 323 and the first pump body 221 must be closed; after the first pump body 221 stops working, the feeding system 2 must be manually disassembled and the blockage must be handled, and it can only be put into use again after reinstallation. And since the first end of the third valve body 311 is respectively connected to the premixing tank 211 of different feeding systems 2, and the second end of the second pump body 322 is connected to the first end of different fifth valve bodies 323, the second end of one fifth valve body 323 is connected to the third end of the first pump body 221 of one feeding system 2. That is to say, after one of the feeding systems 2 is removed, only the fifth valve body 323 needs to be left and the fifth valve body 323 is in a closed state, which will not affect the normal operation of other feeding systems 2.

[0076] Optionally, the feeding pipeline 21 also includes a quantitative feeder 213, the first feed port of the quantitative feeder 213 is connected to the first discharge port of the storage bin 1, the second discharge port of the quantitative feeder 213 is connected to the first end of the first valve body 212, the second end of the first valve body 212 is connected to the second feed port of the premixing tank 211, and the third discharge port of the premixing tank 211 is connected to the first end of the first pump body 221.

[0077] By adding a set amount feeder 213 to control the feeding amount of bait, the feeding amount of the bait throwing machine can be controlled, thereby improving the feeding accuracy of the bait throwing machine.

[0078] Optionally, the quantitative feeder 213 includes a rotary feeder. The rotary feeder adopts a volumetric feeding mode, and the feeding amount of the bait can be controlled by adjusting the rotation speed of the rotary feeder.

[0079] Optionally, the first valve body 212 is a power-off closed solenoid valve; the second valve body 222 , the third valve body 311 , the fourth valve body 321 and the fifth valve body 323 are all electric gate valves.

[0080] When the power to the bait feeder is suddenly cut off, the feeding system 2 suddenly loses its driving force, and the water in the external water area 4 will be pressed into the feeding system 2 due to the liquid level difference. The first valve body 212 can adopt a power-off closed solenoid valve. When the power is suddenly cut off, the first valve body 212 can cut off the connection between the storage bin 1 and the premixing tank 211, and there is a partial space in the premixing tank 211 for temporarily storing water, providing time for the emergency automatic shutdown of the first valve body 212; in this case, feeding can be resumed after power is restored; the second valve body 222, the third valve body 311, the fourth valve body 321 and the fifth valve body 323 of the liquid level detection component 6 are all electric gate valves.

[0081] Optionally, the liquid level detection assembly 6 includes a first liquid level sensor 61, a second liquid level sensor 62, and a third liquid level sensor 63. The first liquid level sensor 61, the second liquid level sensor 62, and the third liquid level sensor 63 are arranged on the inner wall of the premixing tank 211. The first liquid level sensor 61, the second liquid level sensor 62, and the third liquid level sensor 63 are arranged in sequence from the bottom to the top of the premixing tank 211. The first liquid level sensor 61 is used to detect a preset minimum water level, the second liquid level sensor 62 is used to detect a preset middle water level, and the third liquid level sensor 63 is used to detect a preset maximum water level.

[0082] The first pump body 221, the first valve body 212, the second valve body 222, the fourth valve body 321 and the second pump body 322 are all electrically connected to the first liquid level sensor 61; the first pump body 221, the first valve body 212, the second valve body 222, the fourth valve body 321 and the second pump body 322 are all electrically connected to the second liquid level sensor 62; the first pump body 221, the first valve body 212, the second valve body 222, the fourth valve body 321 and the second pump body 322 are all electrically connected to the third liquid level sensor 63.

[0083] The first liquid level sensor 61 is provided at the lower part of the premixing tank 211, the second liquid level sensor 62 is provided at the middle part of the premixing tank 211, the third liquid level sensor 63 is provided at the upper part of the premixing tank 211; when the feeding system 2 is blocked, the first pump body 221 cannot pump out the material-water mixture in the premixing tank 211, and the water pumped into the pipeline 32 cannot be output through the first pump body 221, and may flow back into the premixing tank 211, causing the water level in the premixing tank 211 to rise sharply; when the first liquid level sensor 61 detects that the water in the premixing tank 211 is blocked, the first pump body 221 cannot pump out the material-water mixture in the premixing tank 211, and the water pumped into the pipeline 32 cannot be output through the first pump body 221, and may flow back into the premixing tank 211, causing the water level in the premixing tank 211 to rise sharply. When the water level reaches or exceeds the preset minimum water level, it indicates that a blockage has occurred inside the feeding system 2; the third valve body 311 and the quantitative feeder 213 can be immediately closed to reduce the amount of bait and water input to the premixing tank 211; then a large amount of driving water is continuously pumped into the pumping line 32 to impact the discharge line 22, and at the same time, the first liquid level sensor 61 is used to observe whether the water level in the premixing tank 211 has dropped; if the water level in the premixing tank 211 has dropped, it indicates that the blocked part of the pipeline has been flushed away by the driving water. After using the driving water to flush for a certain period of time, the third valve and the quantitative feeder 213 can be opened to resume feeding.

[0084] If the third valve body 311 and the quantitative feeder 213 are closed and the discharge pipeline 22 is impacted by driving water, the second liquid level sensor 62 detects that the water level in the premixing tank 211 reaches or exceeds the preset middle water level, which means that it is difficult to improve the blockage by driving water impact alone in a short time, and the first valve body 212 needs to be closed to prevent the water in the premixing tank 211 from flowing back into the storage bin 1. At the same time, the water level changes in the premixing tank 211 continue to be detected by the first liquid level sensor 61 and the second liquid level sensor 62. If the water level drops to the preset minimum water level again, it means that the pipeline blockage is completely improved and the feeding operation can be resumed.

[0085] If the third valve body 311 and the quantitative feeder 213 are closed and the driving water is used to impact the discharge pipe 22, the third liquid level sensor 63 detects that the water level in the mixing tank reaches or exceeds the preset maximum water level, which means that it is difficult to solve the blockage problem by relying on the driving water provided by the second pump body 322 and the pressurized jet flushing of the first pump body 221. There is also a risk of the driving water backflowing into the storage bin 1. Therefore, the fifth valve body 323 and the first pump body 221 must be closed at this time; after the first pump body 221 stops working, the feeding system 2 must be manually disassembled and the blockage must be handled, and it can only be put into use again after reinstallation.

[0086] Optionally, the self-input pipeline 31 also includes a first check valve 312, the first end of the first check valve 312 is connected to the second end of the fourth valve body 321, and the second end of the first check valve 312 is connected to the second section of the third valve body 311; the pumping pipeline 32 also includes a second check valve 324, the first end of the second check valve 324 is connected to the second end of the second pump body 322, and the second end of the second check valve 324 is connected to the first end of the fifth valve body 323.

[0087] By providing a first check valve 312 in the self-input pipeline 31, the water in the external water area 4 can only be input into the premixing tank 211 in one direction, thereby preventing the water in the premixing tank 211 from flowing back into the external water area 4; similarly, by providing a second check valve 324 in the pumping pipeline 32, the driving water input from the second pump body 322 to the first pump body 221 can be prevented from flowing back.

[0088] Optionally, the water supply system 3 further includes an auxiliary pipeline 33 having a sixth valve body 331. The first end of the sixth valve body 331 is connected to the second end of the fourth valve body 321, and the second end of the sixth valve body 331 is connected to the second end of the third valve body 311. The first end of the third valve body 311 extends to the bottom wall of the premixing tank 211. By adding the auxiliary pipeline 33 as a supplementary pipeline from the input pipeline 31, when the sixth valve body 331 is opened, the water in the premixing tank 211 can be discharged by utilizing the liquid level difference, so that the first end of the third valve body 311 extends to the bottom wall of the premixing tank 211, thereby facilitating the emptying of the water in the premixing tank 211.

[0089] Optionally, the bottom wall of the storage bin 1 forms a conical structure 11, with a first discharge port provided at the bottom of the conical structure 11. By tilting the bottom wall of the storage bin 1 downward to form the conical structure 11, the first discharge port is provided at the bottom of the conical structure 11. The storage bin 1 delivers the bait to the quantitative feeder 213 through the first discharge port, and the quantitative feeder 213 can control the amount of bait input into the premixing tank 211. The addition of the conical structure 11 utilizes gravity to allow the bait in the storage bin 1 to be concentrated and discharged from the first discharge port.

[0090] Optionally, a third feed port is provided on the top of the storage bin 1 for connecting to an external feed system 5. The external feed system 5 can use a feed pipe, through which bait is manually fed into the storage bin 1 at regular intervals. Alternatively, the external feed system 5 can use an existing automatic pellet feeding mechanism to regularly feed bait into the storage bin 1 in a fixed quantity, thereby improving the ease of use of the bait thrower.

[0091] Optionally, the first pump body 221 includes a water jet pump, and the second pump body 322 includes a water pump. The water jet pump needs to use water at a certain pressure as a working fluid (i.e., the driving water mentioned above) to create a vacuum in the vacuum chamber of the water jet pump. The vacuum chamber generates a low pressure and causes the transported liquid to be sucked into the vacuum chamber and then enter the mixing chamber. The high-energy driving water and the low-energy feed-water mixture in the mixing chamber are fully mixed, so that the energy is exchanged with each other, and the speed gradually becomes consistent before being ejected. The water pump is used to provide driving water for the water jet pump, and also has the function of clearing blockages for the feeding system 2.

[0092] Optionally, the first discharge port of the storage bin 1 is connected to a seventh valve body, which is electrically connected to the liquid level detection assembly 6. If water backflow occurs in the bait feeding machine and the storage bin 1 has been flooded, the water needs to be discharged in time to reduce losses, and the seawater in the feeding system 2 also needs to be discharged during repair or maintenance; first, open the first valve body 212 and the seventh valve body, close the rotary feeder, and at the same time open the third valve body 311, the first check valve 312, the fifth valve body 323, the fourth valve body 321, and the second pump body 322; use the second water pump to suck water out of the storage bin 1 and the premixing tank 211, and discharge it from the discharge pipe 22 of the feeding system 2; wherein, the stationary rotary feeder is used as a separation screen of the storage bin 1 to discharge the water in the storage bin 1 and leave the bait particles. In addition, if there is no water backflow in the storage bin 1, it is only necessary to drain the water in the mixing tank. In this case, it is only necessary to close the seventh valve body and the first valve body 212, and then use the second pump body 322 to pump the water in the premixing tank 211.

[0093] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's description and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
