Description

Technical Field

[0001] This invention relates to the field of livestock feeding, specifically to an intelligent drinking water control system and method for livestock. Background Technology

[0002] With the rapid development of modern pig farming in my country, the amount of nutrients that pigs can directly absorb from feed is limited; adding microorganisms to feed can decompose some indigestible components in the feed and produce various nutrients that are more suitable for pigs to absorb.

[0003] Many factors affect the growth and health of pigs, with drinking water being one of the most important. Currently, almost all waterers on the market are mechanical automatic drinkers. However, these mechanical automatic drinkers have problems such as being clogged by the mouth, leading to insufficient water flow, and the drinker becoming loose and twisted, making it difficult for pigs to reach the water. In addition, some pigs will "play" with the water in the hot summer, even though they don't drink, they still habitually bite the drinker, splashing water onto their bodies to cool down. This causes excessive wear and tear on the drinker, greatly shortening its lifespan, increasing water waste, making the pen damp, and creating slippery floors that can easily cause leg and hoof injuries.

[0004] Existing automatic drinkers such as duckbill and nipple drinkers are all mechanical automatic drinkers, which require pigs to actively drink water when they want to. The mechanical spring-type rebound structure of this type of drinker will have a shortened service life due to the number of water intake activities and impurities. In addition, there are a series of problems such as continuous water leakage and waste due to incomplete rebound, which increases environmental pressure and affects the health of pigs. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent drinking water control system and method for livestock, which can automatically adjust the amount of water consumed according to the needs of pigs and environmental conditions, and at the same time add medicine or nutrient solution to improve the health level and production efficiency of pigs, save water resources and labor costs, and reduce environmental pollution.

[0006] The optimized structure of the present invention is achieved through the following technical solution: a livestock intelligent drinking water control system, including a drug dosing and stirring device, which can stir and transport medicine and nutrient solution; the drug dosing and stirring device is connected to an intelligent drinking water control unit, which is connected to at least one intelligent waterer, and the intelligent drinking water control unit can allocate the water flow to multiple intelligent waterers; the bottom of the intelligent waterer is provided with a feeding trough, which can automatically replenish water to make the water level in the feeding trough reach a set height; a liquid level monitoring device is provided between the intelligent waterer and the feeding trough, which can monitor the water level in the feeding trough in real time.

[0007] In some embodiments, the liquid level monitoring device includes a stainless steel drain pipe connected to the bottom of the smart water dispenser, the bottom of the stainless steel drain pipe extending into the feeding trough, and wires electrically connecting the feeding trough, the stainless steel drain pipe and the smart water control unit.

[0008] In some embodiments, the intelligent drinking water control unit includes an intelligent drinking water controller, which is electrically connected to at least one flow control valve. The flow control valve is located between the dosing and stirring device and the intelligent water dispenser and can feed back the water flow rate to the intelligent drinking water controller.

[0009] In some embodiments, the dosing and stirring device includes a stirring cylinder, a stirring element inside the stirring cylinder, a water distribution pipeline connected to the top of the stirring cylinder, the water distribution pipeline connected to a water delivery device, a water delivery valve connected between the water delivery device and the intelligent drinking water control unit, a liquid delivery pipeline connected to the bottom of the stirring cylinder, the liquid delivery pipeline connected to the intelligent drinking water control unit, a drain valve connected to the bottom of the stirring cylinder, and a high liquid level sensor and a low liquid level sensor installed on the stirring cylinder.

[0010] In some embodiments, the water distribution pipeline includes a water distribution valve connected to the water delivery device, and a flow valve is connected between the water distribution valve and the mixing tank.

[0011] In some embodiments, the liquid delivery pipeline includes a liquid delivery pump connected to the bottom of the stirring tank, and a liquid delivery valve is connected between the liquid delivery pump and the intelligent drinking water control unit.

[0012] In some embodiments, the water supply valve, the water distribution valve, and the liquid delivery valve are all connected in parallel with a manual control valve; a three-way pipe is connected between the water supply valve and the liquid delivery valve, and a filter is connected between the three-way pipe and the intelligent drinking water control unit.

[0013] In some embodiments, the dosing and stirring device, the intelligent drinking water control unit, and the intelligent water dispenser are all electrically connected to the control system, and corresponding parameters can be input to control the water flow of the intelligent water dispenser.

[0014] A method for intelligent drinking water control for livestock includes the following steps:

[0015] Step S1: Determine whether the pigsty needs water or liquid supply based on the on-site situation; if water is needed, proceed to step S2; if liquid is needed, proceed to step S3.

[0016] Step S2: Keep the water distribution valve and the liquid delivery valve closed, and the water delivery valve continuously supplies water to the pigsty; when the pigs drink the water in the trough to a level below the set height, the intelligent waterer automatically and periodically replenishes a fixed amount of water to the trough until the liquid level monitoring device detects that the water level is higher than the set height again and stops replenishing water.

[0017] Step S3: Based on the site conditions, input parameters such as the number of pigs in different pens and the required water volume into the control system; the dosing and stirring device receives the parameters input by the control system, opens the water distribution valve, manually mixes and adds the medicine, starts the stirring element to stir, and after reaching the set water volume, closes the water distribution valve and stops stirring after the first stirring time, allowing the mixture in the stirring tank to stand for a certain period of time, and then the stirring element stirs for the second time to reach the second stirring time; continue to step S4;

[0018] Step S4: Close the water supply valve, start the liquid delivery pump, open the liquid delivery valve, and deliver the mixture in the stirring tank to the intelligent drinking water control unit, then continue to step S5;

[0019] Step S5: The intelligent drinking water control unit distributes the mixed liquid to each of the intelligent drinking water dispensers according to the set parameters. The intelligent drinking water dispensers dispense the mixed liquid into the corresponding feeding tank. When the low liquid level sensor detects a low water level in the stirring tank, it shuts off the liquid delivery pump and the liquid delivery valve, and starts the water delivery valve to complete the liquid supply.

[0020] In some embodiments, step S6 is further included: after the liquid supply is completed, the water distribution valve is started, the agitator is started, the agitator is agitated for a period of time, the water distribution valve is closed, the drain valve is opened to drain the sewage, the drain valve is closed after a period of sewage discharge, and the cycle is repeated once to clean the agitator.

[0021] The water distribution valve is activated to bring the water level in the mixing tank to the required level for cleaning. The water distribution valve is then closed, and the mixing element stops stirring. The water delivery valve is closed, the liquid delivery pump is activated, and the liquid delivery valve is opened to deliver the water in the mixing tank to the intelligent drinking water control unit and then to each of the feeding troughs. When the low liquid level sensor detects a low water level in the mixing tank, the liquid delivery pump and the liquid delivery valve are closed, and the water delivery valve is activated to clean the liquid delivery pipeline. Simultaneously, after the liquid supply is completed, the system switches to water supply mode to ensure the pigs' normal drinking water needs.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] like Figure 1 As shown, an intelligent drinking water control system for livestock includes a medicine dosing and stirring device 1, an intelligent drinking water control unit 2, and at least one intelligent drinker 3. The medicine dosing and stirring device 1, the intelligent drinking water control unit 2, and the intelligent drinker 3 are all electrically connected to the control system, and the water dispensing volume of the intelligent drinker 3 can be controlled by inputting corresponding parameters.

[0036] The dosing and stirring device 1 can stir and transport liquid medicine and nutrient solution. The dosing and stirring device 1 includes a stirring cylinder 11, inside which is a stirring element 12, which can be a stirring motor with a stirring rod. A water distribution pipeline is connected to the top of the stirring cylinder 11, which may include a water distribution valve 15 connected to a water delivery device. A flow valve 16 is connected between the water distribution valve 15 and the stirring cylinder 11. The water distribution pipeline is connected to a water delivery device, and a water delivery valve 13 is connected between the water delivery device and the intelligent drinking water control unit 2. A liquid delivery pipeline is connected to the bottom of the stirring cylinder 11. The system includes a liquid delivery pump 17 connected to the bottom of the mixing tank 11, a liquid delivery valve 18 connected between the liquid delivery pump 17 and the intelligent drinking water control unit 2, and a liquid delivery pipeline connected to the intelligent drinking water control unit 2; a drain valve 14 connected to the bottom of the mixing tank 11; a high liquid level sensor and a low liquid level sensor are installed on the mixing tank 11; the mixing element 12, the high liquid level sensor, and the low liquid level sensor are all electrically connected to the control system. The high liquid level sensor and the low liquid level sensor can feed back the measured liquid level data to the control system, which can control the start, stop, and mixing duration of the mixing element 12. The control system may include a control unit and a user terminal, where corresponding parameters can be input. The user terminal controls the operation of the dosing and mixing device 1, the intelligent drinking water control unit 2, and the intelligent water dispenser 3 through the control unit.

[0037] The user terminal interface may include a start button, a stirring button, a liquid delivery button, and a cleaning button. The start button can be a regular start, while the stirring, liquid delivery, and cleaning buttons can be used for cross-level starts. Users can select the appropriate function button according to different needs to achieve cross-level operation and skip parts of the process. Cross-level starts are valid only when the equipment is stopped to ensure the normal operation of the entire system. The user terminal interface may also include a reset button to initialize the operation process, allowing the system to restart in the first step sequence using the start button again. When starting via the cross-level start button, the previously unfinished process will be automatically initialized and run according to the cross-level start process. The control unit has a data retention function, allowing it to continue from the previous unfinished stage and complete the entire process control when manually stopped or abnormally stopped and then manually restarted.

[0038] The dosing and stirring device 1 is connected to the intelligent drinking water control unit 2. The control points of the dosing and stirring device 1 can be connected to the IO module. The IO module transmits data to the intelligent drinking water control unit 2 via 485 communication, thereby enabling the intelligent drinking water control unit 2 to remotely control the dosing and stirring device 1.

[0039] The intelligent drinking control unit 2 is connected to at least one intelligent drinker 3. The intelligent drinking control unit 2 can allocate water flow to multiple intelligent drinkers 3. It can control the water flow between the medication mixing device 1 and the intelligent drinkers 3 based on parameters input to the control system or automatically collected data, and feed back the water flow to the intelligent drinking controller to achieve precise feeding and drinking. The intelligent drinkers 3 have a feeding trough 4 at their bottom, which can automatically replenish water to maintain a set water level. A liquid level monitoring device is installed between the intelligent drinkers 3 and the feeding trough 4 to monitor the water level in the feeding trough 4 in real time, preventing the water level from being too high or too low, which could affect the pigs' drinking quality and comfort. The liquid level monitoring device includes a stainless steel lower part connected to the bottom of the intelligent drinkers 3. The water pipe, a stainless steel drain pipe, extends from the bottom into the feeding trough 4, which can be made of stainless steel. The feeding trough 4, the stainless steel drain pipe, and the intelligent drinking control unit 2 are all electrically connected by wires. The stainless steel drain pipe is used as a probe to detect the water level in the feeding trough 4. Specifically, the probe detection line has two poles: one pole connects to the stainless steel drain pipe, and the other pole connects to a metal frame or metal connecting piece. The probe connects to the feeding trough 4 through the metal frame or metal connecting piece. When the liquid in the feeding trough 4 reaches the position of the stainless steel drain pipe, an electrical signal is activated, thus detecting the water level in the feeding trough 4. This reduces the need for additional detection equipment, avoids affecting the pigs' feeding, and lowers equipment investment costs. When the stainless steel drain pipe is fixed, it is encased in a PVC pipe for external insulation.

[0040] When pigs drink the water in the feed trough 4 until it falls below the set height, the level monitoring device sends a signal to the intelligent drinker 3 via a wire. The intelligent drinker 3 then automatically replenishes water in the feed trough 4 based on the signal. This continues until the level monitoring device detects the water level is above the set height again. At this point, the level monitoring device sends a signal to the intelligent drinker 3 via a wire, and the intelligent drinker 3 stops replenishing water. When the water level in the pipeline between the intelligent drinker 3 and the intelligent drinking control unit 2 is insufficient, the intelligent drinker 3 sends a signal to the intelligent drinking control unit 2. Based on the signal, the intelligent drinking control unit 2 controls the flow control valve to open, allowing water to flow from the medicine mixing device 1 through the intelligent drinking control unit 2 to the intelligent drinker 3. The flow control valve then feeds back the flow data to the intelligent drinking control unit 2, which, based on the signal, controls the flow control valve to close, stopping water replenishment. In this way, the intelligent waterer 3 can automatically replenish water, ensuring a constant water level in the feed trough 4, making it convenient for pigs to drink water. At the same time, it can prevent the water level from being too high or too low, which would affect the drinking quality and comfort of the pigs. It can also reduce water waste and splashing, keeping the pen dry and clean.

[0041] The intelligent drinking water control unit 2 includes an intelligent drinking water controller 21, which is electrically connected to at least one flow control valve 22. The flow control valve 22 is located between the drug mixing device 1 and the intelligent drinker 3 and can provide feedback on the water flow to the intelligent drinking water controller 21. The flow control valve 22 can be an integrated electromagnetic flow valve. The intelligent drinking water controller 21 controls the opening and closing of the integrated electromagnetic flow valve and receives pulse feedback on the water flow from the integrated electromagnetic flow valve to achieve precise control of the water flow. The intelligent drinking water controller 21 distributes the mixed liquid to each intelligent drinker through the flow control valve 22. According to parameters such as the number of pigs in different pens and the required water flow, the flow of water from each intelligent drinker is adjusted so that each pig can get an appropriate amount of mixed liquid, avoiding waste or insufficient water.

[0042] In some embodiments, the water supply valve 13, the water distribution valve 15, and the liquid delivery valve 18 are all connected in parallel with a manual control valve, which can be used as an emergency control device when the corresponding solenoid valve is abnormally damaged; a three-way pipe is connected between the water supply valve 13 and the liquid delivery valve 18, and a filter 19 is connected between the three-way pipe and the intelligent drinking water control unit 2, which can filter the liquid flowing to the intelligent drinking water control unit 2 and extend the service life of the intelligent drinking water control unit 2 and the intelligent water dispenser 3.

[0043] A method for intelligent drinking water control for livestock includes the following steps:

[0044] Step S1: Determine whether the pigsty needs water or liquid supply based on the on-site situation; if water is needed, proceed to step S2; if liquid is needed, proceed to step S3.

[0045] In step S2, the water distribution valve 15 and the liquid delivery valve 18 are kept closed, and the water delivery valve 17 continuously supplies water to the pigsty. When the pigs drink the water in the feed trough 4 to a level below the set height, the intelligent waterer 3 automatically and periodically replenishes a fixed amount of water to the feed trough 4 until the liquid level monitoring device detects that the water level is higher than the set height again and then stops replenishing water.

[0046] Step S3: Based on the site conditions, input parameters such as the number of pigs in different pens and the required water volume into the control system; the drug dosing and stirring device 1 receives the parameters input from the control system and opens the water distribution valve 15. After a 10-second delay, manually mix and add the drug, start the stirring element 12 to stir, and after reaching the set water volume, close the water distribution valve 15 and stop stirring after the stirring element 12 reaches the first stirring time. Let the mixture in the stirring tank 11 stand for a certain period of time to ensure the uniformity and stability of the mixture. The stirring element 12 stirs a second time to reach the second stirring time. This avoids sedimentation or stratification of the drug solution or nutrient solution, improves the drinking water quality and effect for the pigs, and continues to step S4; the first stirring time, the second stirring time, and the certain standing time can be adjusted according to the different drug solutions and nutrient solutions to achieve a better mixing effect.

[0047] Step S4: Close the water supply valve 13, start the liquid supply pump 17, open the liquid supply valve 18, and deliver the mixed liquid in the mixing tank 11 to the intelligent drinking water control unit 2, then continue to step S5.

[0048] In step S5, the intelligent drinking water control unit 2 distributes the mixed liquid to each intelligent water dispenser 3 according to the set parameters. The intelligent water dispenser 3 then pours the mixed liquid into the corresponding feeding tank 4. When the low liquid level sensor detects a low water level in the stirring tank 11, it shuts off the liquid delivery pump 17 and the liquid delivery valve 18, and starts the water delivery valve 13 to complete the liquid supply.

[0049] In some embodiments, step S6 is further included: after the liquid supply is completed, the water distribution valve 15 is started, and after a delay of 10 seconds, the agitator 12 is started. After a period of agitation, the water distribution valve 15 is closed, and the drain valve 14 is opened to drain the wastewater. After a period of draining the wastewater, the drain valve 14 is closed, and the process is repeated once to achieve cleaning of the agitator 11. During the draining process, the agitator 12 can increase the turbulence of the cleaning water in the agitator 11, making it easier to clean the agitator 11 and improving the cleaning effect of the agitator 11. At the same time, it can prevent blockage during draining.

[0050] Start the water distribution valve 15 to bring the water level in the mixing tank 11 to the required level for cleaning. Then, close the water distribution valve 15, stop the mixing element 12, close the water supply valve 13, start the liquid delivery pump 17, and open the liquid delivery valve 18 to deliver the water in the mixing tank 11 to the intelligent drinking water control unit 2 and then to each feed trough 4. When the low liquid level sensor detects a low water level in the mixing tank 11, it closes the liquid delivery pump 17 and the liquid delivery valve 18, and starts the water delivery valve 13 to clean the liquid delivery pipeline. At the same time, after the liquid supply is completed, it switches to the water supply state to ensure the normal drinking water needs of the pigs.

[0051] The specific workflow for liquid delivery is as follows: Figure 2 As shown, based on the site conditions, parameters such as the number of pigs in different pens and the required water volume are set. The set parameters are input into the user terminal, and the system is started normally. When the start button is pressed, and the high liquid level sensor does not detect relevant data and the liquid in the mixing tank 11 is not at a high liquid level, the water distribution valve 15 is started. After a delay of 10 seconds, the medicine is manually added according to the ratio, and the mixing element 12 is started to stir. After the set water volume is reached, the water distribution valve 15 is closed, and the mixing element 12 stops stirring after reaching the first stirring time. After the mixture in the mixing tank 11 has stood for a certain period of time, the mixing element 12 stirs for the second time. After reaching the second stirring time, the preparation of medicine solution and nutrient solution is completed.

[0052] At this time, close the water supply valve 13, start the liquid supply pump 17, open the liquid supply valve 18, and transport the mixture in the stirring tank 11 to the intelligent drinking water control unit 2. The intelligent drinking water control unit 2 distributes the mixture to each intelligent water dispenser 3 according to the set parameters. The intelligent water dispenser 3 pours the mixture into the corresponding feeding tank 4. When the low liquid level sensor detects a low water level in the stirring tank 11, it closes the liquid supply pump 17 and the liquid supply valve 18, and starts the water supply valve 13 to complete the liquid supply.

[0053] The low liquid level sensor detects the low liquid level in the mixing tank 11, shuts off the liquid delivery pump 17 and the liquid delivery valve 18, starts the water distribution valve 15, and after a 10-second delay, starts the agitator 12. After mixing for a period of time, the water distribution valve 15 is closed, the drain valve 14 is opened to drain the wastewater, and after draining the wastewater for a period of time, the drain valve 14 is closed and the cycle is repeated once to clean the mixing tank 11.

[0054] Start the water distribution valve 15 to bring the water level in the mixing tank 11 to the required level for cleaning. Then, close the water distribution valve 15, stop the mixing element 12, close the water supply valve 13, start the liquid delivery pump 17, and open the liquid delivery valve 18 to deliver the mixed liquid in the mixing tank 11 to the intelligent drinking water control unit 2. When the low liquid level sensor detects a low water level in the mixing tank 11, it closes the liquid delivery pump 17 and the liquid delivery valve 18, and starts the water delivery valve 13 to clean the liquid delivery pipeline. At the same time, after the liquid supply is completed, it switches to the water supply state to ensure the normal drinking water needs of the pigs.

[0055] In some embodiments, the present invention can be linked with an existing dry material line control system to form a wet mixing system; specifically, the dry material line system detects whether the dry material line needs to be replenished through a material level switch, thereby realizing automatic replenishment of the dry material line system.

[0056] The water supply time and amount are determined by the watering time, the amount of dry feed required per pig, and the water-to-feed ratio. The relevant parameters are then input into the intelligent drinking control system. The intelligent drinking control system delivers water to the feed trough and simultaneously drives the dry feed line system to feed the dry feed, so that the dry feed and water are mixed to achieve wet feed feeding.

[0057] The control unit obtains the watering time corresponding to the next parameter configured with the required dry feed amount per pig, and uses this as the next automatic feeding time; that is...

[0058] Feeding time = Watering time for this meal + Delayed feeding time after watering;

[0059] Material replenishment can be performed by setting a timer, with a maximum of 8 timer settings supported. The process will not take effect when the input value is 0.

[0060] In summary, this invention, through the drug mixing device 1, the intelligent drinking water control unit 2, and the intelligent drinker 3, can automatically adjust the drinking water volume and simultaneously add medicine or nutrient solution, achieving precise control and adjustment of parameters such as drinking water volume and water quality in the pigsty. This improves drinking water efficiency and water quality safety, meets the different physiological needs of pigs, promotes pig growth, improves pig health and production efficiency, saves water resources and costs, reduces environmental pollution, and improves the level of breeding management. By adopting the intelligent drinker 3 and the liquid level monitoring device, automatic water replenishment and real-time monitoring of the water level in the feed trough 4 can be achieved, avoiding problems such as injury to pigs, easy damage, and water waste caused by mechanical drinkers. It ensures a dry environment and prevents environmental damage caused by water waste from affecting pig health, thus eliminating the environmental pressure and increased costs caused by water waste.

The intelligent drinking water control system for livestock according to claim 1, characterized in that: The dosing and stirring device (1), the intelligent drinking water control unit (2), and the intelligent water dispenser (3) are all electrically connected to the control system, and the corresponding parameters are input to control the water flow of the intelligent water dispenser (3).

3. A method for intelligent drinking water control for livestock, using an intelligent drinking water control system for livestock as described in any one of claims 1-2, characterized in that, Includes the following steps: Step S1: Determine whether the pigsty needs water or liquid supply based on the on-site situation; if water is needed, proceed to step S2; if liquid is needed, proceed to step S3. In step S2, the water distribution valve (15) and the liquid delivery valve (18) are kept closed, and the water delivery valve (13) continuously supplies water to the pigsty. When the pigs drink the water in the feed trough (4) to a level lower than the set height, the intelligent waterer (3) automatically and periodically replenishes a fixed amount of water to the feed trough (4) until the liquid level monitoring device detects that the water level is higher than the set height again and then stops replenishing water. Step S3: Based on the site conditions, input the number of pigs in different pens and the required water volume parameters into the control system; the dosing and stirring device (1) receives the parameters input by the control system and opens the water distribution valve (15) to manually mix and add medicine, start the stirring element (12) to stir, and after reaching the set water volume, close the water distribution valve (15), and stop stirring after the stirring element (12) reaches the first stirring time, and let the mixture in the stirring tank (11) stand for a certain time, and then the stirring element (12) stirs for the second time to reach the second stirring time; continue to step S4; Step S4: Close the water supply valve (13), start the liquid delivery pump (17), open the liquid delivery valve (18), and deliver the mixture in the stirring tank (11) to the intelligent drinking water control unit (2), then continue to step S5; In step S5, the intelligent drinking water control unit (2) distributes the mixed liquid to each of the intelligent drinking water dispensers (3) according to the set parameters. The intelligent drinking water dispenser (3) pours the mixed liquid into the corresponding food trough (4). When the low liquid level sensor detects a low water level in the stirring tank (11), it shuts off the liquid delivery pump (17) and the liquid delivery valve (18) and starts the water delivery valve (13) to complete the liquid supply.

4. The intelligent drinking water control method for livestock according to claim 3, characterized in that, It also includes step S6, after the liquid supply is completed, start the water distribution valve (15), start the agitator (12), after stirring for a period of time, close the water distribution valve (15), open the drain valve (14) to drain the sewage, after draining the sewage for a period of time, close the drain valve (14), and cycle once to clean the agitator (11); Start the water distribution valve (15) to make the water volume in the mixing tank (11) reach the cleaning water volume, close the water distribution valve (15), the mixing element (12) stops mixing, close the water supply valve (13), start the liquid delivery pump (17), open the liquid delivery valve (18), and deliver the water in the mixing tank (11) to the intelligent drinking water control unit (2) and flow to each of the feeding troughs (4). When the low liquid level sensor detects the low water level in the mixing tank (11), close the liquid delivery pump (17) and the liquid delivery valve (18), and start the water supply valve (13) to clean the liquid delivery pipeline; at the same time, after the liquid supply is completed, switch to the water supply state to ensure the normal drinking water needs of the pigs.
