Description

Technical Field

[0001] This invention belongs to the field of livestock and poultry breeding technology and equipment, specifically relating to an automated cleaning and disinfection device and disinfection method for pig farms. Background Technology

[0002] Biosecurity management is crucial in pig farming, and disinfection centers, as a vital component of biosecurity management, are increasingly being used in pig farms. People and materials entering the pig farm undergo cleaning and disinfection at these centers, preventing the introduction of viruses and significantly reducing the risk of disease in pigs. The design of a disinfection center primarily includes two functional areas: washing and drying. Washing mainly involves bathing personnel, cleaning vehicles, and spraying disinfectant on materials, while drying primarily involves drying vehicles.

[0003] While disinfection centers are widely used, they also have many shortcomings. Common problems include: incomplete disinfection and sampling of incoming materials: typically, incoming materials are only sprayed with disinfectant before sampling and testing. In this case, only the outer surface of the materials is disinfected, which cannot ensure that the materials inside the packaging are virus-free. Sampling and testing cannot completely cover all aspects, meaning that disinfected materials still pose a risk. Inadequately designed personnel access routes: personnel can easily cross over before and after showering, and the lack of clear separation poses a risk of recontamination after showering. Furthermore, feed truck drivers often lack well-designed access routes, making it impossible to ensure that drivers are disinfected in the disinfection center without causing environmental pollution.

[0004] US Patent Application No. US17203804 discloses a portable car wash assembly. The invention includes a frame with multiple legs and a roof, allowing the vehicle's drive unit to be positioned beneath the frame. Multiple first sprayers are mounted on the frame to spray liquid onto the vehicle, and multiple second sprayers are mounted on the frame to spray liquid onto the vehicle. A first fluid pump is mounted on a support cage to pump fluid and soapy water into the first sprayers for vehicle washing. A second fluid pump is mounted on the frame and is in fluid communication with each second sprayer to spray the mixture of fluid and soapy water onto the vehicle for washing. This invention effectively cleans stains on the vehicle body and recycles the used soapy water, achieving energy conservation and environmental protection. However, it is difficult to effectively remove feed, feces, and bacteria adhering to the underside of vehicles entering and leaving farms, easily causing ground pollution. Summary of the Invention

[0005] The purpose of this invention is to provide an automated cleaning and disinfection device and method for pig farms that can efficiently, comprehensively, and automatically clean and sterilize feed vehicles.

[0006] The technical solution adopted by this invention to achieve the above objectives is as follows: an automated cleaning and disinfection device for pig farms, comprising: a connected vehicle washing shed, a material parking area, and a drying shed. The vehicle washing shed is equipped with detection probes, a vehicle undercarriage cleaning device, and a vehicle body cleaning device. The detection probes are arranged around the vehicle undercarriage cleaning device, and the vehicle body cleaning device is mounted above it. After a vehicle enters the vehicle washing shed, it can stop above the vehicle undercarriage cleaning device. The detection probes control the vehicle undercarriage cleaning device and the vehicle body cleaning device to perform comprehensive cleaning of the vehicle's body and chassis, achieving automated cleaning and reducing labor costs.

[0007] Preferably, the vehicle undercarriage cleaning device includes a parking ramp spaced apart, with a base having grooves fixed between the ramps. A base plate is movably mounted within the grooves of the base, and a sterilization plate assembly is connected above the base plate. A cleaning plate assembly capable of spraying water is oscillatingly connected to the side of the sterilization plate assembly. The driver drives the vehicle to the wheel wells and stops it on the parking ramp. The sterilization and cleaning plate assemblies sterilize and wash the undercarriage. The parking ramp facilitates wheel positioning and guidance, ensuring the sterilization plate is aligned with the vehicle undercarriage, improving the cleaning effect. Simultaneously, the parking ramp raises the undercarriage, allowing dirt to flow down with the washing water, preventing water accumulation and re-contamination at the bottom. The movable base plate expands the disinfection range of the sterilization and cleaning plate assemblies, further improving the disinfection rate of dirt and bacteria.

[0008] Preferably, the sterilization plate assembly includes a top plate and a bottom plate arranged at intervals. Both the top and bottom plates are light-transmitting plates, and ultraviolet lamps are symmetrically arranged within the intervals. A hydraulic cylinder connects the bottom plate and the base plate. The ultraviolet lamps emit light that passes through the top plate and the floor to sterilize the underside of the vehicle and the space below it, preventing the possibility of dirt adhering to the surface after cleaning due to water mist. The hydraulic cylinder can raise and lower the bottom and top plates to accommodate vehicles with different chassis heights for disinfection and sterilization. It also prevents vehicles with low chassis from directly hitting the top plate and the cleaning plate assembly, thus extending the service life of the device and reducing maintenance costs.

[0009] Preferably, the cleaning plate assembly includes a rotating shaft hinged to the side of the top plate. Multiple parallel and spaced partitions are fixed to the rotating shaft. Each partition has multiple embedded tubes, and a rotating ring is connected above each tube. The tubes are connected to a delivery pipe assembly. A telescopic rod is hinged to the side of the bottom plate and the bottom of the partitions. The delivery pipe assembly delivers external water to each tube, which is then sprayed out from the rotating ring to wash away dirt from the undercarriage. The rotating rings on the multiple partitions expand the washing range, and the spaced partitions facilitate the water flow carrying dirt down through the gaps, preventing the top plate from being covered by dirt and affecting the diffusion of the ultraviolet light source. It also allows for the placement of a collection box under the partitions for dirt collection, facilitating subsequent floor cleaning. The telescopic rod can control the extension length to change the angle of the partitions relative to the top plate, thereby expanding the cleaning range of the rotating rings. During the swinging process, residual dirt on the partitions also falls off, preventing dirt from clogging the partitions and contacting the vehicle chassis.

[0010] Preferably, the rotating ring includes a nozzle with arrayed openings on its top and side walls, and a mounting hole at its bottom. A bearing is installed in the mounting hole, and the nozzle is rotatably connected to the upper end of the insertion tube via the bearing. Water enters the nozzle from the insertion tube and is sprayed outward through the openings on the top and sides of the nozzle. Simultaneously, the nozzle rotates relative to the insertion tube under the impact of the water, forming impact water flows in multiple directions, further enhancing the cleaning effect of the nozzle on the underside of the vehicle.

[0011] Preferably, the delivery pipe assembly includes a main pipe spirally wound around an ultraviolet lamp. Multiple partitions are fixed below the same branch pipe, which is connected to branch pipes at the bottom of each insertion pipe. One end of the main pipe is connected to the branch pipe, and the other end is connected to a water pump. Water is pumped through the main pipe, branch pipe, branch pipe, and each insertion pipe before being sprayed from the nozzle. As the water passes through the main pipe, the ultraviolet lamp sterilizes the water using its ultraviolet light source, allowing the nozzle to spray clean water to wash the undercarriage, reducing the possibility of bacterial residue. The spiral winding of the main pipe increases the contact time between the ultraviolet light source and the water, improving the sterilization effect. It also provides external protection for the ultraviolet lamp, preventing it from breaking and reducing maintenance costs while preventing damage to the undercarriage from lamp explosion. The pump's water delivery speed affects the expansion of the main pipe, thereby adjusting the gap between the top and bottom plates and increasing the likelihood of dirt falling off the partitions.

[0012] Preferably, the vehicle body cleaning device includes a gantry bracket mounted above the undercarriage cleaning device, the gantry bracket is connected to a cleaning cylinder, a motor-driven rotating shaft is fixed inside the cleaning cylinder, and an array of mounting kits is arranged on the wall of the cleaning cylinder, with cleaning heads movably mounted inside the mounting kits.

[0013] Preferably, the inner wall of the assembly has a spiral groove, and the cleaning head includes a ball on the side wall that engages with the spiral groove. A spring connects the cleaning head to the assembly on one side inside the cleaning cylinder, and a soft brush is provided on the other side of the cleaning head. The motor drives the rotating shaft to rotate the cleaning cylinder. Under the action of centrifugal force, the cleaning head slides away from the axis of the rotating shaft within the assembly. During the sliding process, the ball slides in the spiral groove, realizing the rotation and sliding of the cleaning head relative to the assembly. This increases the cleaning range of the cleaning head on the vehicle body and avoids the problem of cleaning dead corners caused by gaps between adjacent cleaning heads. When the outward-extending cleaning head contacts the vehicle body, it compresses the spring, causing the cleaning head to retract and preventing the cleaning head from extending too far and scratching the vehicle body. At the same time, the vibration caused by the extension and contraction of the spring can be transmitted to each cleaning head through the rotating cylinder, which helps to vibrate and remove residual dirt on the soft brush at the outer end of the cleaning head, ensuring the effect of the next cleaning.

[0014] Preferably, the material parking area is divided into a soaking room and a shower room, both of which are connected to the material parking area, and the shower room is connected to the car wash shed.

[0015] This invention, employing a multi-directionally adjustable undercarriage cleaning device and body cleaning device for disinfecting incoming vehicles, offers the following advantages: The parking ramp accelerates vehicle positioning and parking while raising the chassis, facilitating vehicle cleaning and preventing ground dirt from contaminating the chassis; the sterilization and cleaning plate assemblies can slide and rise relative to the base, expanding cleaning coverage and adapting to vehicles with different chassis heights for cleaning and disinfection, preventing damage to the chassis impact device; the partitions spray water onto the undercarriage for cleaning via rotating rings, and the spacing of the partitions allows water to carry dirt down through the gaps, preventing dirt accumulation on the top plate from affecting the diffusion of ultraviolet light, and facilitating dirt collection in the bottom collection box for subsequent ground cleaning. The partition, oscillating via a telescopic rod, expands the cleaning range while generating vibration, accelerating the removal of dirt and preventing secondary contamination after cleaning the vehicle's undercarriage. Ultraviolet lamps sterilize the internal water of the main pipe wrapped around the partition, achieving disinfection through sprayed cleaning water, further enhancing the sterilization and cleaning effect. Additionally, the main pipe protects the outside of the ultraviolet lamp, preventing it from bursting and damaging the vehicle's undercarriage, and reducing maintenance costs. The rotating cleaning cylinder allows the cleaning head to slide outwards in a rotating manner, overcoming cleaning blind spots. The cleaning head, spring-loaded, ensures cleaning effectiveness without excessive contact with the vehicle body, preventing damage. The vibration from the spring's extension and contraction accelerates dirt removal, ensuring the effectiveness of subsequent cleaning. Therefore, this invention is an automated cleaning and disinfection device and method for pig farms, enabling highly efficient, multi-directional, and automated cleaning and sterilization of feed vehicles.

Detailed Implementation

[0027] The technical solution of the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings:

[0028] Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] See appendix Figure 1 An automated cleaning and disinfection system for pig farms includes: a connected car wash shed 1, a material parking area 2, and a drying shed 3. The car wash shed 1 is equipped with detection probes 10, a vehicle undercarriage cleaning device 4, and a vehicle body cleaning device 9. The detection probes 10 are positioned around the vehicle undercarriage cleaning device 4. The vehicle body cleaning device 9 is mounted above the vehicle undercarriage cleaning device 4.

[0030] The material parking area 2 is divided into a soaking room 20 and a shower room 21. Both the soaking room 20 and the shower room 21 are connected to the material parking area 2, and the shower room 21 is connected to the car wash shed 1.

[0031] The detection probe 10 is connected to a controller. After the detection probe 10 detects that the vehicle is completely stationary for a certain period of time, it sends a signal to the controller, which then controls the undercarriage cleaning device 4 and the body cleaning device 9 to start and operate.

[0032] After entering the car wash shed 1, the vehicle can stand above the undercarriage cleaning device 4. The undercarriage cleaning device 4 and the body cleaning device 9 are controlled by sensors 10 to perform a comprehensive cleaning of the vehicle's body and chassis, achieving automated cleaning and reducing labor costs. After cleaning, personnel return to drive the vehicle into the drying shed 3 to dry.

[0033] See appendix Figure 3 The undercarriage cleaning device 4 includes parking ramps 40 spaced apart, a base 41 with grooves fixed between the parking ramps 40, a base plate 42 movably disposed in the groove of the base 41, a sterilization plate assembly 5 connected above the base plate 42, and a cleaning plate assembly 6 capable of spraying water swaying to the side of the sterilization plate assembly 5.

[0034] The driver drives the vehicle to the wheel hub and stops it on the parking ramp 40. The chassis is sterilized and rinsed by the sterilization plate group 5 and the cleaning plate group 6. The parking ramp 40 helps to position and guide the wheels, ensuring that the sterilization plate is directly facing the chassis, thus improving the cleaning effect. At the same time, the parking ramp 40 raises the chassis, which helps to allow dirt to flow down with the rinsing water and prevents the bottom water from accumulating and causing re-contamination. The movable base plate 42 expands the sterilization range of the sterilization plate group 5 and the cleaning plate group 6, further improving the sterilization rate of dirt and bacteria.

[0035] See appendix Figure 4 A driving mechanism 43 is provided between the substrate 42 and the base 41. The driving mechanism 43 includes a stepper motor 44 fixed to the side of the substrate 42. The stepper motor 44 extends upward along its motor axis and is fixed with a gear 45. A rack 46 that cooperates with the gear 45 is fixed in a groove in the base 41. The stepper motor 44 is connected to an encoder. By presetting the rotation time of the stepper motor 44 in the encoder, the length of the movement trajectory of the gear 45 on the rack 46 and the direction of the gear 45 are controlled. This allows the substrate 42 to automatically slide back and forth along a specified path in the groove in the base 41, realizing the horizontal movement of the sterilization plate group 5 and the cleaning plate group 6, expanding the sterilization range, and avoiding incomplete local cleaning.

[0036] See appendix Figure 5 The sterilization plate assembly 5 includes a top plate 50 and a bottom plate 51 arranged at intervals. Both the top plate 50 and the bottom plate 51 are light-transmitting plates, and ultraviolet lamps 52 are symmetrically arranged within the intervals. A hydraulic cylinder 53 connects the bottom plate 51 and the base plate 42. The ultraviolet lamps 52 emit light that passes through the top plate 50 and the floor to sterilize the bottom of the vehicle and the space below it, preventing the possibility of dirt adhering to the surface after cleaning due to water mist. The hydraulic cylinder 53 can raise and lower the bottom plate 51 and the top plate 50 to accommodate vehicles with different chassis heights for disinfection and sterilization. It also prevents vehicles with low chassis from directly hitting the top plate 50 and the cleaning plate assembly 6, thereby extending the service life of the device and reducing maintenance costs.

[0037] The cleaning plate assembly 6 includes a rotating shaft 9260 hinged to the side of the top plate 50. The rotating shaft 9260 is fixed with multiple parallel and spaced partitions 61. Each partition 61 is embedded with multiple insertion tubes 62. Each insertion tube 62 is connected to a rotating ring 7. The insertion tube 62 is connected to a delivery pipe assembly 8. A telescopic rod 63 is hinged to the side of the bottom plate 51 and the bottom of the partition 61. The delivery pipe assembly 8 delivers external water to each insertion pipe 62 and then sprays it out from the rotating ring 7 to wash away dirt from the undercarriage. The rotating ring 7 on multiple baffles 61 expands the washing range, and the spaced baffles 61 facilitate the water flow to carry dirt down from the gaps, preventing the top plate 50 from being covered by dirt and affecting the diffusion of the ultraviolet light source. At the same time, it is convenient to place a box under the baffles 61 to collect dirt, which is convenient for subsequent ground cleaning. The telescopic rod 63 can control the extension length to change the tilt angle of the baffles 61 relative to the top plate 50, thereby expanding the cleaning range of the rotating ring 7. During the swinging process, it is also conducive to the falling of residual dirt on the baffles 61, preventing dirt from clogging the baffles 61 and contacting the chassis.

[0038] See appendix Figure 8 The rotating ring 7 includes a nozzle 70, which has an array of openings on its top and side walls. A mounting hole 71 is located at the bottom of the nozzle 70, and a bearing 72 is installed within the mounting hole 71. The nozzle 70 is rotatably connected to the upper end of the insertion tube 62 via the bearing 72. Water enters the nozzle 70 through the insertion tube 62 and is sprayed outwards through the openings on the top and sides of the nozzle 70. Simultaneously, under the impact of the water, the nozzle 70 rotates relative to the insertion tube 62 via the bearing 72, forming impact water flows in multiple directions, further enhancing the cleaning effect of the nozzle 70 on the underside of the vehicle.

[0039] See appendix Figure 6 -Appendix Figure 7 The delivery pipe assembly 8 includes a main pipe 80, which is spirally wound around an ultraviolet lamp 52. A common water distribution pipe 81 is fixed below multiple partitions 61. The water distribution pipe 81 is connected to the bottom of each insertion pipe 62 via branch pipes 82. One end of the main pipe 80 is connected to the water distribution pipe 81, and the other end is connected to a water pump 83. Water is pumped by water pump 83 and passes through main pipe 80, branch pipe 81, branch pipe 82 and various insertion pipes 62 before finally being sprayed out from nozzle 70. When the water passes through main pipe 80, ultraviolet lamp 52 sterilizes the water in main pipe 80 with ultraviolet light source, so that nozzle 70 sprays clean water to wash the bottom of the car, reducing the possibility of bacteria residue on the bottom of the car. The spiral winding of main pipe 80 increases the contact time between ultraviolet light source and water, improving the sterilization effect of water, and at the same time forms an outer protection for ultraviolet lamp 52 to prevent it from breaking, reducing maintenance costs and preventing lamp body from exploding and damaging the bottom of the car. The speed at which the pump delivers water affects the expansion of main pipe 80, thereby adjusting the distance between top plate 50 and bottom plate 51, increasing the probability of dirt falling off partition 61.

[0040] See appendix Figure 9The vehicle body cleaning device 9 includes a gantry bracket 90 mounted above the undercarriage cleaning device 4. The gantry bracket 90 is connected to a cleaning cylinder 91. A motor-driven rotating shaft 9260 is fixed inside the cleaning cylinder 91. The cleaning cylinder 91 is equipped with an array of mounting accessories 93. A cleaning head 94 is movably mounted inside the mounting accessories 93.

[0041] See appendix Figure 10 The inner wall of the accessory 93 has a spiral groove 95. The cleaning head 94 includes a ball 96 on the side wall that engages with the spiral groove 95. A spring 97 connects the cleaning head 94 to the accessory 93 on one side inside the cleaning cylinder 91. A soft brush is provided on the other side of the cleaning head 94. The motor drives the rotating shaft 9260 to rotate the cleaning cylinder 91. Under the action of centrifugal force, the cleaning head 94 slides away from the axis of the rotating shaft 9260 within the mounting 93. During the sliding process, the ball 96 slides within the spiral groove 95, enabling the cleaning head 94 to rotate and slide relative to the mounting 93. This increases the cleaning range of the cleaning head 94 on the vehicle body and avoids the problem of cleaning dead corners caused by gaps between adjacent cleaning heads 94. When the outward-extending cleaning head 94 contacts the vehicle body, it compresses the spring 97, causing the cleaning head 94 to retract and preventing the cleaning head 94 from extending too far and scratching the vehicle body. At the same time, the vibration caused by the extension and contraction of the spring 97 can be transmitted to each cleaning head 94 through the rotating cylinder, which helps to vibrate and remove residual dirt on the soft brush at the outer end of the cleaning head 94, ensuring the effect of the next cleaning.

[0042] The automated disinfection system in pig farms uses the following disinfection methods:

[0043] Step 1: The driver drives the feed truck to stop at material parking area 2;

[0044] Step 2: Unload the supplies and ingredients from the feed truck and put them into the soaking room 20 for soaking, disinfection and cleaning;

[0045] Step 3: The driver drives the unloaded feed truck into the car wash shed 1 and stops above the undercarriage cleaning device 4;

[0046] Step four: The driver gets out of the vehicle and enters shower room 21 for body cleaning and disinfection;

[0047] Step 5: After the detection probe 10 detects that the feed truck has been stationary for a preset time, it controls the undercarriage cleaning device 4 and the body cleaning device 9 to clean and disinfect the vehicle, removing any remaining feed and attached dirt.

[0048] Step six: After cleaning, the driver drives the vehicle into drying shed 2 for drying.

[0049] An automatic transfer track can be installed between the parking slope 40 and the drying shed 2 according to site requirements. The automatic transfer track is also controlled by the detection probe 10 and the controller connected to it. After the detection probe detects that the cleaning process is completed, the controller controls the automatic transfer track to directly transfer the vehicle to the drying shed 2 for drying.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
