Description

Technical Field

[0001] This invention relates to the field of pig farm disinfection technology, and in particular to a disinfection system and method for a pig farm environment. Background Technology

[0002] Pig farming is an important industry in my country's agriculture, playing a vital role in ensuring the safe supply of meat. my country's pig farming industry is transforming from traditional pig farming to modern pig farming, with significant changes occurring in breeding models, regional layout, production methods, and production capacity.

[0003] In recent years, the diversification and prevalence of diseases have caused enormous economic losses to the livestock industry. Prevention is key in livestock farming, and proper protection, especially the purification and disinfection of pig farms, is particularly important for livestock production. Pig farms are large-scale pig-raising sites, generating large amounts of pig manure and wastewater, resulting in poor internal environments that easily breed many pathogens. Disinfection is a crucial measure for preventing disease infection and outbreaks on pig farms, ensuring safe and stable production. Regular disinfection operations are necessary during the breeding process.

[0004] However, disinfection operations in pig farms require a lot of manpower. Pig pens are large, and the workload of manually spraying disinfectant is huge. Moreover, since disinfectant may damage the pigs' eyes, respiratory tract, and even digestive tract, the pigs need to be driven out of the pig pens before disinfection operations are carried out. The large area of ​​the pig pens and the large number of pigs undoubtedly increase the labor cost of disinfection operations by a huge amount, making the efficiency very low.

[0005] The technical problem this solution aims to solve is to provide a farm environment disinfection system that is highly efficient in disinfection and can simplify the process of herding pigs. Summary of the Invention

[0006] In order to achieve the above-mentioned objectives and address the above-mentioned technical problems, the present invention provides a disinfection system and method for aquaculture farms.

[0007] The technical solution includes a mobile vehicle that travels in the pig farm aisle. The mobile vehicle includes a chassis, a disinfectant tank is installed on the chassis, a disinfection pole is installed on the top of the disinfectant tank, a nozzle is installed on the top of the disinfection pole, and a motor, a water pump and a filter are also installed on the top of the disinfectant tank.

[0008] The mobile vehicle is equipped with electric wheels at its bottom;

[0009] The mobile vehicle is equipped with a main controller, an AGV card reader is installed at the bottom of the vehicle chassis, and magnetic strips are installed on the floor of the passageway, with RFID landmark cards installed at the nodes of the magnetic strips.

[0010] The AGV is controlled by a PLC. The mobile vehicle is equipped with a wireless communication system, which allows it to communicate wirelessly with the main controller, report its operating position and working status, and execute the main controller's instructions. The AGV reader reads ground markings through RFID landmark cards and performs corresponding actions such as changing speed, turning, positioning, and stopping. The mobile vehicle is equipped with an AGV reader at its bottom, and RFID landmark cards are installed at the nodes on the ground. Each landmark card at a node is assigned an ID number and definition. For example, node A represents the AGV turning and is represented by the ID number 00001. Once the mobile vehicle passes through point A, the AGV reader will read the electronic tag ID number at point A, and the PLC will make the mobile vehicle perform the corresponding action based on the read data.

[0011] The disinfection pole is equipped with an electrically operated telescopic rod at its top. A rotating base is rotatably connected to the top of the telescopic rod, and a crossbar is mounted on top of the rotating base. One end of the crossbar is rotatably connected to the top of the rotating base, and the other end is rotatably connected to a nozzle base. The nozzle is fixedly connected to the nozzle base. The electric telescopic rod is adjustable in height. The rotating base is rotatable; for areas that the spray path cannot reach, such as passageways and corners, the nozzle's lateral angle can be rotated by the rotating base to disinfect those areas. Both the crossbar and the nozzle base can be driven to rotate by their respective motors.

[0012] The nozzle base rotates at a speed controlled by a motor, causing the nozzle to spray from the pig farm floor to the side wall and then to the roof. Since linear velocity = angular velocity * radius, if the nozzle base rotates at a constant speed, the spray radius is small and the linear velocity is slow when spraying the floor, resulting in more disinfectant being sprayed and a better disinfection effect. When spraying the roof, the spray radius is large and the linear velocity is fast, resulting in less residual disinfectant at the sprayed areas. Therefore, to achieve a better disinfection effect, the rotation speed is slower when spraying the roof.

[0013] The nozzle is connected to the disinfectant tank via a flexible pipe, and the top of the disinfectant tank is equipped with a dosing port.

[0014] The entire pig farm consists of several pig pens located on both sides of the passageway. The pig pens are arranged symmetrically on both sides of the passageway, and each pig pen is equipped with a pig herding mechanism.

[0015] The pig-driving mechanism includes a screw drive unit and two vertical plates driven by the screw drive unit. Sliding plates are fixedly installed on both sides of the two vertical plates, and through holes are provided on the sliding plates.

[0016] Pig herding organizations can herd pigs without having to drive them out of the pigsty, and can also separate the disinfection area from the area where the pigs are located. Because disinfectants are harmful to pigs, the current practice is generally to drive the pigs out of the pigsty and then spray disinfectant.

[0017] The pigsty fence has two symmetrical sets of support rods on both sides, each set including two support rods at both ends of the pigsty.

[0018] The lead screw drive unit includes lead screw one and lead screw two disposed between one set of support rods, and sliding rod one and sliding rod two disposed between another set of support rods.

[0019] The second lead screw is located above the first lead screw, and the second sliding rod is located above the first sliding rod;

[0020] The through hole on one side of the vertical plate is threadedly connected to the lead screw, and the through hole on the other side of the vertical plate is slidably connected to the sliding rod and the sliding rod.

[0021] The through hole on one side of the sliding plate of the second vertical plate is threadedly connected to the second lead screw, and the through hole on the other side of the sliding plate of the second vertical plate is slidably connected to the first sliding rod and the second sliding rod respectively.

[0022] Both ends of lead screw one and lead screw two are rotatably connected to the support rod, and both ends of sliding rod one and sliding rod two are fixedly connected to the support rod. Both lead screw one and lead screw two are driven to rotate by their respective lead screw motors.

[0023] The lead screw motor is electrically connected to the main controller of the mobile vehicle.

[0024] Both the first and second uprights have slots at their tops, and electric telescopic plates are installed inside the slots.

[0025] Both the first and second vertical plates have rotating grooves at their bottoms. Two rotating plates are arranged side by side in the rotating grooves, and the tops of the rotating plates are rotatably connected to the inner wall of the top of the rotating groove.

[0026] When the rotating plate is parallel to the first and second vertical plates, the sides of the two rotating plates come into contact.

[0027] The disinfection method based on the farm environment disinfection system includes the following steps:

[0028] S1. In the initial state, both upright plate one and upright plate two are located at one end of the pigsty and are in close contact with each other, leaving space for the pigs to move around normally. At this time, the rotating plate is parallel to upright plate one and upright plate two.

[0029] S2. When disinfection is required in the pigsty, the mobile vehicle moves along the track set in the passageway and adjusts the vertical height through the electric telescopic rod; the crossbar and the nozzle base are driven to rotate by their respective motors; the nozzle base is controlled by the motor to rotate at a certain speed, so that the spray trajectory of the nozzle is from the pig farm floor to the side wall and then to the top surface, and the speed gradually slows down as the spray radius increases.

[0030] For areas that the spray cannot reach, such as passageways and corners, the nozzle can be rotated laterally by rotating the rotating seat to disinfect them.

[0031] At the same time, the lead screw motor drives the second lead screw to rotate, thereby moving the second vertical plate to the other end of the pigsty until it stops in the middle of the pigsty. Since the rotating plates are parallel to the first and second vertical plates, the first and second vertical plates are closed, forming an isolation and disinfection zone between the first and second vertical plates. The second vertical plate divides the pigsty into two zones: the isolation and disinfection zone and the buffer zone. The second vertical plate isolates the pigs in the buffer zone.

[0032] The electric telescopic panel inside the trough rises until it is close to the top of the pigsty;

[0033] S3. The nozzle is aimed at the isolation and disinfection area, and the disinfection operation is carried out according to the spray trajectory from the pig farm floor to the side wall and then to the top.

[0034] S4. When the mobile vehicle reaches a certain position, the AGV card reader reads the electronic tag ID number at the node. Based on the read data, the PLC causes the mobile vehicle to return to the origin to add medicine, and then return to the node to continue the disinfection work.

[0035] S5. After the disinfection work of the first isolation and disinfection zone formed in step S2 is completed, the rotating plate on the second upright plate rotates and opens, forming three channels on the second upright plate. The screw motor of the second screw starts again, driving the second upright plate to move to the other end of the pig house until it touches the fence at the other end. At this time, the rotating plate on the second upright plate rotates and closes. Then the screw motor of the second screw rotates in the opposite direction, and the second upright plate moves to the direction of the initial position until it moves to the middle of the pig house and stops, thereby isolating the pigs in the closed area between the first upright plate and the second upright plate, that is, in the first isolation and disinfection zone formed in step S2 where the disinfection work has been completed. At this time, there are no pigs in the buffer zone formed in step S2, and the nozzles on the mobile vehicle can carry out disinfection work in this area.

[0036] S5. After completing the disinfection work of the entire pigsty, the rotating plate on the second upright plate rotates open and continues to move in the direction of the initial position until it is in contact with the first upright plate and returns to the initial state.

[0037] S6. After completing the disinfection work in one pigsty, the mobile vehicle can continue to move forward and complete the disinfection work in the adjacent pigsty.

[0038] When the mobile vehicle is moving, it can simultaneously carry out disinfection work on both sides of the pigsty by rotating the rotating seat.

[0039] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows: This solution provides a disinfection system and disinfection method for a farm environment. By controlling the mobile vehicle to walk in the passageway, the pigsty is disinfected. The nozzle base is controlled by a motor to rotate at a certain speed, so that the spray trajectory of the nozzle is from the pig farm floor to the side wall and then to the top surface. As the spray radius increases, the rotation speed gradually slows down, ensuring the disinfection effect of each location.

[0040] When the mobile vehicle reaches a certain position, the AGV card reader reads the electronic tag ID number at the node. Based on the read data, the PLC causes the mobile vehicle to return to the origin to add medicine, and then return to the node to continue the disinfection work, which improves the efficiency of the disinfection operation.

[0041] Furthermore, the use of this system eliminates the need for manual herding of pigs or driving the pigs out of the pen. Instead, the system uses a screw drive unit to control the movement of the upright plate, dividing the pigsty into an isolation and disinfection area and a buffer zone. This separates the disinfection operation area from the area where the pigs are located, greatly simplifying the disinfection preparation work while preventing the pigs from being sprayed with disinfectant, thus ensuring the health of the pigs.

[0054] Example 1

[0055] See Figures 1 to 7 The present invention provides a disinfection system and method for a farm environment, including a mobile vehicle 1 that moves in the passageway 3 of the pig farm. The mobile vehicle 1 includes a chassis 101, a disinfection tank 102 on the chassis 101, a disinfection pole 103 on the top of the disinfection tank 102, a nozzle 104 on the top of the disinfection pole 103, and a motor 105, a water pump 106 and a filter 107 on the top of the disinfection tank 102.

[0056] The mobile vehicle 1 is equipped with electric wheels 108 at its bottom;

[0057] The mobile vehicle 1 is equipped with a main controller, the bottom of the vehicle chassis 101 is equipped with an AGV card reader 2, the passageway 3 is equipped with a magnetic strip 4, and the node positions of the magnetic strip 4 are equipped with RFID landmark cards.

[0058] The AGV is controlled by a PLC. The mobile vehicle is equipped with a wireless communication system, which allows it to communicate wirelessly with the main controller, report its operating position and working status, and execute the main controller's instructions. The AGV reader reads ground markings through RFID landmark cards and performs corresponding actions such as changing speed, turning, positioning, and stopping. The mobile vehicle is equipped with an AGV reader at its bottom, and RFID landmark cards are installed at the nodes on the ground. Each landmark card at a node is assigned an ID number and definition. For example, node A represents the AGV turning and is represented by the ID number 00001. Once the mobile vehicle passes through point A, the AGV reader will read the electronic tag ID number at point A, and the PLC will make the mobile vehicle perform the corresponding action based on the read data.

[0059] The disinfection pole 103 is equipped with an electric telescopic pole 5 at its top. A rotating base 6 is rotatably connected to the top of the electric telescopic pole 5. A crossbar 7 is mounted on the top of the rotating base 6. One end of the crossbar 7 is rotatably connected to the top of the rotating base 6, and the other end is rotatably connected to a nozzle base 8. The nozzle 104 is fixedly connected to the nozzle base 8. The electric telescopic pole is adjustable in height. The rotating base is rotatable; for areas that the spray path cannot reach, such as passageways and corners, the nozzle's lateral angle can be rotated by the rotating base to disinfect them. Both the crossbar and the nozzle base can be driven to rotate by their respective motors.

[0060] The nozzle base rotates at a speed controlled by a motor, causing the nozzle to spray from the pig farm floor to the side wall and then to the roof. Since linear velocity = angular velocity * radius, if the nozzle base rotates at a constant speed, the spray radius is small and the linear velocity is slow when spraying the floor, resulting in more disinfectant being sprayed and a better disinfection effect. When spraying the roof, the spray radius is large and the linear velocity is fast, resulting in less residual disinfectant at the sprayed areas. Therefore, to achieve a better disinfection effect, the rotation speed is slower when spraying the roof.

[0061] The nozzle 104 is connected to the disinfectant tank 102 via a flexible pipe, and the disinfectant tank 102 is equipped with a dosing port on the top.

[0062] The entire pig farm consists of several pig houses 9 set on both sides of the passageway 3. The pig houses 9 on both sides of the passageway 3 are symmetrically arranged, and each pig house 9 is equipped with a pig herding mechanism.

[0063] The pig herding mechanism includes a screw drive unit and two vertical plates 21 and 22 driven by the screw drive unit. Sliding plates 12 are fixedly installed on both sides of the vertical plates 21 and 22, and each sliding plate 12 is provided with a through hole.

[0064] Pig herding organizations can herd pigs without having to drive them out of the pigsty, and can also separate the disinfection area from the area where the pigs are located. Because disinfectants are harmful to pigs, the current practice is generally to drive the pigs out of the pigsty and then spray disinfectant.

[0065] Two sets of symmetrical support rods 10 are installed on both sides of the pigpen 9 fence, each set including two support rods 10 installed at both ends of the pigpen 9;

[0066] The lead screw drive unit includes lead screw 31 and lead screw 32 disposed between one set of support rods 10, and sliding rod 33 and sliding rod 34 disposed between another set of support rods 10.

[0067] Lead screw 2 32 is located above lead screw 1 31, and sliding rod 2 34 is located above sliding rod 1 33;

[0068] The through hole on the sliding plate 12 on one side of the vertical plate 21 is threadedly connected to the lead screw 31, and the through hole on the sliding plate 12 on the other side of the vertical plate 21 is slidably connected to the sliding rod 33 and the sliding rod 34 respectively.

[0069] The through hole on the sliding plate 12 on one side of the vertical plate 22 is threadedly connected to the lead screw 2 32, and the through hole on the sliding plate 12 on the other side of the vertical plate 22 is slidably connected to the sliding rod 1 33 and the sliding rod 2 34 respectively.

[0070] The two ends of lead screw 1 31 and lead screw 2 32 are rotatably connected to support rod 10, and the two ends of sliding rod 1 33 and sliding rod 2 34 are fixedly connected to support rod 10. Lead screw 1 31 and lead screw 2 32 are both driven to rotate by their respective lead screw motors.

[0071] The lead screw motor is electrically connected to the main controller of the mobile vehicle 1.

[0072] Both upright plate 1 21 and upright plate 2 22 have slots at their tops, and electric telescopic plates 13 are installed in the slots.

[0073] Both upright plate 11 and upright plate 22 have a rotating groove 14 at their bottom. Two rotating plates 15 are arranged side by side in the rotating groove 14. The top of the rotating plates 15 are rotatably connected to the inner wall of the top of the rotating groove 14.

[0074] When the rotating plate 15 is parallel to the vertical plate 21 and the vertical plate 22, the sides of the two rotating plates 15 come into contact.

[0075] The disinfection method based on the farm environment disinfection system includes the following steps:

[0076] S1. In the initial state, both upright plate 1 21 and upright plate 22 are located at one end of the pig house 9 and are in close contact with each other, leaving space for the pigs to move around normally. At this time, the rotating plate 15 is parallel to upright plate 1 21 and upright plate 22.

[0077] S2. When disinfection is required in pigsty 9, the mobile vehicle 1 moves along the track set in the passageway 3 and adjusts the vertical height through the electric telescopic rod 5; the crossbar 7 and the nozzle base 8 are both driven to rotate by their respective motors; the nozzle base 8 controls the rotation speed through the motor, which drives the nozzle 104 to spray from the pig farm floor to the side wall and then to the top surface, and the rotation speed gradually slows down as the spray radius increases.

[0078] For areas that the spray cannot reach, such as passageways and corners, the nozzle 104 can be disinfected by rotating the rotating seat 6 to change the lateral angle.

[0079] At the same time, the lead screw motor drives the lead screw 2 32 to rotate, thereby moving the vertical plate 2 22 to the other end of the pig house 9 until it stops in the middle of the pig house. Since the rotating plate 15 is parallel to the vertical plate 1 21 and the vertical plate 2 22, the vertical plate 1 21 and the vertical plate 2 22 are closed, forming an isolation and disinfection zone between the vertical plate 1 21 and the vertical plate 2 22. The vertical plate 2 22 divides the pig house 9 into two zones: the isolation and disinfection zone and the buffer zone. The vertical plate 2 22 isolates the pigs in the buffer zone.

[0080] The electric telescopic plate 13 inside the trough rises until it is close to the top surface of the pigsty 9;

[0081] S3, Nozzle 104 is aimed at the isolation and disinfection area, and disinfection is carried out according to the spray trajectory from the pig farm floor to the side wall and then to the top.

[0082] S4. When the mobile vehicle 1 reaches a certain position, the AGV card reader 2 reads the electronic tag ID number at the node. Based on the read data, the PLC causes the mobile vehicle 1 to return to the origin to add medicine, and then return to the node to continue the disinfection work.

[0083] S5. After the disinfection work of the first isolation and disinfection zone formed in step S2 is completed, the rotating plate 15 on the second upright plate 22 rotates and opens, forming three channels on the second upright plate 22. The screw motor of the second screw 32 starts again, driving the second upright plate 22 to move to the other end of the pig house 9 until it touches the fence at the other end. At this time, the rotating plate 15 on the second upright plate 22 rotates and closes. Then the screw motor of the second screw 32 rotates in the opposite direction, and the second upright plate 22 moves in the direction of the initial position until it moves to the middle of the pig house and stops, thereby isolating the pigs in the closed area between the first upright plate 21 and the second upright plate 22, that is, in the first isolation and disinfection zone formed in step S2 where the disinfection work has been completed. At this time, there are no pigs in the buffer zone formed in step S2, and the nozzle 104 on the mobile vehicle 1 can carry out disinfection work in this area.

[0084] S5. After completing the disinfection work of the entire pigsty 9, the rotating plate 15 on the upright plate 22 rotates and opens, and continues to move in the direction of the initial position until it is in contact with the upright plate 1 21 and returns to the initial state.

[0085] S6. After completing the disinfection work of one pig house 9, the mobile vehicle 1 can continue to move forward and complete the disinfection work of the adjacent pig house 9.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

When the pigsty (9) needs to be disinfected, the mobile vehicle (1) moves along the track set in the passageway (3) and adjusts the vertical height through the electric telescopic rod (5); the crossbar (7) and the nozzle base (8) are driven to rotate by their respective motors; the nozzle base (8) controls the rotation speed through the motor, and drives the nozzle (104) to spray from the pig farm floor to the side wall and then to the top surface, and the rotation speed gradually slows down as the spray radius increases; For areas that the motion trajectory cannot reach, the nozzle (104) can be rotated by rotating the seat (6) to rotate the lateral angle of the nozzle (104) to disinfect them; At the same time, the screw motor drives the screw two (32) to rotate, thereby driving the upright plate two (22) to move towards the other end of the pig house (9) until it stops in the middle of the pig house. Since the rotating plate (15) is parallel to the upright plate one (21) and the upright plate two (22), the upright plate one (21) and the upright plate two (22) are closed, and an isolation and disinfection zone is formed between the upright plate one (21) and the upright plate two (22). The upright plate two (22) divides the pig house (9) into two zones: the isolation and disinfection zone and the buffer zone. The upright plate two (22) isolates the pigs in the buffer zone. The electric telescopic plate (13) inside the slot rises until it is close to the top surface of the pig house (9); S3. The nozzle (104) is aimed at the isolation and disinfection area, and the disinfection operation is carried out according to the spray trajectory from the pig farm floor to the side wall and then to the top. S4. When the mobile vehicle (1) reaches a certain position, the AGV card reader (2) reads the electronic tag ID number at the node. Based on the read data, the PLC makes the mobile vehicle (1) return to the origin to add medicine, and then return to the node to continue the disinfection work. S5. After the disinfection work of the first isolation disinfection area formed in step S2 is completed, the rotating plate (15) on the second upright plate (22) rotates open, forming three channels on the second upright plate (22). The screw motor of the second screw (32) starts again, driving the second upright plate (22) to move to the other end of the pig house (9) until it touches the fence at the other end. At this time, the rotating plate (15) on the second upright plate (22) rotates close, and then the screw motor of the second screw (32) rotates in the opposite direction, and the second upright plate (22) moves in the direction of the initial position until it moves to the middle of the pig house and stops, thereby isolating the pigs in the closed area between the first upright plate (21) and the second upright plate (22), that is, in the first isolation disinfection area formed in step S2 where the disinfection work has been completed. At this time, there are no pigs in the buffer zone formed in step S2, and the nozzle (104) on the moving vehicle (1) can carry out disinfection work in this area. S5. After completing the disinfection work of the entire pigsty (9), the rotating plate (15) on the second upright plate (22) rotates and opens, and continues to move in the direction of the initial position until it fits against the first upright plate (21) and returns to the initial state. S6. After completing the disinfection work of a pigsty (9), the mobile vehicle (1) can continue to move forward and complete the disinfection work of the adjacent pigsty (9).
