Description

Technical Field

[0001] The present invention relates to the technical field of disease prevention and control of African swine fever and other diseases transmitted by direct, indirect contact or aerosol, and specifically to an epidemic prevention type pig delivery system. Background Art

[0002] African swine fever (ASF) is an acute, hemorrhagic, and highly contagious disease caused by the African swine fever virus (ASFV) infecting pigs. The onset of African swine fever is short, and the mortality rate of the most acute and acute infections is as high as 100%. African swine fever is an infectious disease that is extremely harmful to the pig farming industry. There is currently no effective vaccine, so prevention and control measures are particularly important.

[0003] External pig transport trucks are one of the important ways to spread the African swine fever virus. When selling pigs, pig farms set up pig exit areas outside the pig farms to avoid direct contact between external pig transport trucks and pig farm production personnel or equipment. The pigs in the farm are moved from the farm to the pig exit area for temporary storage. External pig transport trucks are parked in designated pig receiving areas, and staff drive the pigs for sale from the pig exit area to the pig receiving area through the pig driving channel. The Chinese patent with application publication number CN205946830U discloses a live pig exit channel, including a live pig temporary storage area, an exit channel, a floor scale and a liftable platform, which are connected in sequence. The exit channel is an enclosed exit channel, and the liftable platform is an integral liftable structure. Although this design speeds up the pig output and reduces labor costs, it has the following problems:

[0004] 1) Although the exit channel is closed, the distance between the pig entry and exit is too close, and there is a lack of effective control measures for airborne viruses. African swine fever virus can be transmitted through aerosols, posing a great safety risk.

[0005] 2) The lack of effective isolation measures between staff and external pig transport vehicles increases the risk of cross infection.

[0006] How to effectively prevent and control the spread of swine fever virus during the pig farming process is an important problem currently facing the pig farming industry. Summary of the invention

[0007] The present invention provides an epidemic prevention type pig delivery system, which can solve the problem that the spread of swine fever virus cannot be effectively prevented and controlled during the pig delivery process.

[0008] The present application provides the following technical solutions: a quarantine-type pig-discharging system, comprising a pig-discharging area and a pig-receiving area, wherein the pig-discharging area and the pig-receiving area are isolated by a partition, and a closed pig-driving passage is arranged between the pig-discharging area and the pig-receiving area, wherein the pig-entry end of the closed pig-driving passage is located in the pig-discharging area, and the pig-exit end of the closed pig-driving passage is located in the pig-receiving area, and an air filtration system is arranged in the closed pig-driving passage.

[0009] Beneficial effects: By setting physical isolation such as partitions and closed pig driving passages between the pig delivery area and the pig receiving area, direct contact between people, objects and pigs is prevented, the possibility of cross contamination is reduced, and external pollutants are prevented from entering the interior of the passage. At the same time, the internal environment is kept stable, which helps to maintain suitable temperature, humidity and other conditions and improve the comfort of pigs. Air is treated by an air filtration system, which can effectively remove particulate matter, bacteria and viruses in the air, ensure the air quality in the pig house, and significantly reduce the risk of airborne transmission. In the process of transporting pigs, a multi-level protection system is formed, which greatly improves the overall biosafety. The epidemic prevention pig delivery system of the present application is easy to implement, has good protection effect, and is low cost.

[0010] Furthermore, a vertical lifting platform is provided at the pig entry end and / or the pig exit end of the enclosed pig driving passage.

[0011] Beneficial effects: The vertical lifting platform can adjust the height of the platform at any time according to actual needs to ensure docking with the carriage of the transport vehicle or other receiving devices, improve the efficiency of pig transportation and save manpower.

[0012] Furthermore, a one-way door is provided in the enclosed pig-driving passage to prevent the pigs from falling back.

[0013] Beneficial effect: The one-way door only allows pigs to pass in one direction, and once they pass through, they cannot return, ensuring a one-way flow path for pigs from the pig exit area to the pig receiving area, reducing the risk of pathogen transmission between different areas.

[0014] Furthermore, the barrier is a partition or a wall.

[0015] Beneficial effect: The design of partitions or walls can significantly enhance the physical isolation effect of the system, ensure strict separation between the pig delivery area and the pig receiving area, and effectively prevent the cross-transmission of pathogens. Moreover, the materials are readily available, the cost is low, and it is easy to implement.

[0016] Furthermore, a visual window is provided on the barrier member.

[0017] Beneficial effect: It is convenient for staff and outsiders to observe each other's situation and communicate simply through gestures

[0018] Furthermore, the air filtration system includes an air inlet arranged at the top of the closed pig-driving passage, and the air inlet is provided with an outer cover, a primary air filter, a high-efficiency air filter and a positive pressure blower in sequence from the outside to the inside, and air outlets are provided on both sides of the bottom of the closed pig-driving passage.

[0019] Beneficial effects: The combination of primary air filters and high-efficiency air filters can effectively remove various pollutants in the air, including bacteria and viruses, significantly reducing the risk of airborne transmission of viruses. By maintaining a positive pressure state in the channel, external pollutants and pathogens are prevented from entering the channel through door gaps or other gaps, thereby enhancing the level of biosafety protection. Reasonable airflow design not only improves air quality and sanitary conditions, but also improves the comfort of pigs in the channel and reduces stress reactions.

[0020] Furthermore, a sensor is provided on the enclosed pig-driving passage, and the sensor is connected to the air filtration system.

[0021] Beneficial effects: By cooperating with the sensor and the air filtration system, the air filtration system can be automatically turned on or off, effectively preventing and controlling viruses and reducing the risk of cross infection.

[0022] Furthermore, the sensor is a radar sensing device and / or an infrared sensing device.

[0023] Beneficial effects: The radar sensing device and the infrared sensing device each have their own characteristics and can be used separately or in combination to form a comprehensive monitoring system.

[0024] Furthermore, a monitoring camera is provided on the enclosed pig-driving passage, and the monitoring camera is connected to a computer terminal and / or a handheld terminal.

[0025] Beneficial effects: Management personnel can access the monitoring screen at any time and grasp the on-site situation at any time, which improves the response speed and enhances the automation level and management efficiency of the epidemic prevention pig delivery system.

[0026] Furthermore, the enclosed pig-driving passage has a width of 1 to 1.2 m and a length of 10 to 15 m.

[0027] Beneficial effects: The width of 1 to 1.2 meters ensures that pigs can only pass in a single file, avoiding crowding and confusion, and reducing stress reactions. The length of 10 to 15 meters satisfies the physical isolation distance, effectively reducing direct contact between the pig delivery area and the pig receiving area, and reducing the risk of cross contamination.

The visual window can be made of glass or transparent resin material. A closed pig-driving passage 2 is provided between the pig-discharging area and the pig-receiving area. The pig-entry end of the closed pig-driving passage 2 is located in the pig-discharging area, and the pig-exit end of the closed pig-driving passage 2 is located in the pig-receiving area. A vertical lifting platform 5 is provided at the pig-entry end port and the pig-exit end port of the closed pig-driving passage 2. Multiple one-way doors are evenly distributed in the closed pig-driving passage 2 to prevent pigs from falling back. The width of the passage for pigs to pass through the inner side of the closed pig-driving passage 2 is 1.2m and the length is 10m. The vertical lifting platform 5 includes a fence, and a cylinder lifting mechanism is provided under the fence. The cylinder lifting mechanism is used to support the fence and push the fence to move vertically up and down. A remote control device is provided on the vertical lifting platform 5, and the lifting, stopping, etc. of the vertical lifting platform 5 is controlled by remote control. The outer perimeter width of the fence is 2m and the length is 3m. There are movable doors at both ends of the length direction of the fence. The movable doors can be lateral sliding doors or lifting doors. After the movable door on the fence close to the enclosed pig driving passage is opened, it can be connected to the enclosed pig driving passage 2; after the movable door on the fence far from the enclosed pig driving passage 2 is opened, it can be connected to the carriage of the external vehicle.

[0033] An air filtration system is provided in the closed pig-driving passage 2, and the air filtration system includes a plurality of air inlets 3 arranged at the top of the closed pig-driving passage 2, and the interval between two adjacent air inlets 3 is 1.5-2m. The air inlet 3 is provided with an outer cover, a primary air filter, a high-efficiency air filter and a positive pressure blower from the outside to the inside, and air outlets 4 are provided on both sides of the bottom of the closed pig-driving passage. The outer cover adopts a blind or a window that can be opened and closed automatically, and the width of the outer cover is 0.4-0.5m and the length is 0.6-0.8m. The positive pressure blower sends the air filtered by the primary air filter and the high-efficiency air filter in sequence into the closed pig-driving passage; the air entering the closed pig-driving passage 2 is discharged outward through the air outlets 4 provided on both sides of the bottom, thereby reducing the risk of pathogens in the pig receiving area being transmitted to the pig leaving area. When piglets are transported, the wind speed at the positive pressure blower outlet is 0.3-0.5m / s. When fattening pigs are transported, the wind speed at the positive pressure blower outlet is 1.5-2.5m / s.

[0034] A sensor is provided at the pig outlet of the enclosed pig driving passage 2, and the sensor is connected to the air filtration system through a controller. The sensor adopts a radar sensing device, and the radar sensing device includes a sensor unit, a signal processing unit and a data transmission unit. The sensor unit includes a plurality of sensors, and the plurality of sensors are evenly distributed on the pig outlet of the enclosed pig driving passage 2 to ensure all-round coverage, and can detect moving objects in the sensing area. The sensing area is an area within 2-2.5m of the outer periphery of the pig outlet of the enclosed pig driving passage 2. The signal processing unit is connected to the sensor unit, receives the echo signal from the sensor, analyzes the echo signal, and extracts the target information. The data transmission unit is used to send the target information extracted by the signal processing unit to the controller. After receiving the information sent by the sensor, the controller is used to send an opening or closing instruction to the outer cover and the positive pressure blower connected to the air filtration system.

[0035] A surveillance camera is provided at the pig exit end of the enclosed pig driving channel 2. The surveillance camera is communicatively connected with the computer terminal and the handheld terminal.

[0036] Here’s how to use it:

[0037] When transporting pigs, the pigs in the pig farm are transported to the vertical lifting platform 5 of the pig delivery area, the air filtration system is turned on, and the external pig transport vehicle is parked on the vertical lifting platform 5 of the pig receiving area away from one end of the closed pig driving passage 2, and the pigs are driven from the vertical lifting platform 5 of the pig delivery area through the closed pig driving passage 2 to the vertical lifting platform 5 of the pig receiving area, and then driven to the external pig transport vehicle to complete the pig delivery operation. If the external pig transport vehicle arrives at the pig receiving area first, and the air filtration system is not turned on, since the sensor, that is, the radar sensing device is always in a working state, when an external vehicle or an outsider enters the sensing area, the radar sensing device transmits a signal to the controller. After receiving the signal, the controller sends an opening command to the outer cover, the outer cover is opened, and then sends an opening command to the positive pressure blower, the positive pressure blower starts to work, and the outside air passes through the outer cover, the primary air filter, the high efficiency air filter and the positive pressure blower in turn into the closed pig driving passage 2, moves downward, and is discharged outward through the air outlets 4 on both sides of the bottom of the closed pig driving passage. When a foreign vehicle or person enters the sensing area and leaves, the radar sensing device transmits a signal to the controller, which receives the signal and sends a closing command to the outer cover and positive pressure blower after a set delay time.

[0038] Embodiment 2

[0039] The difference between this embodiment and the first embodiment is that a plurality of sensors are evenly distributed inside the closed pig-driving passage 2, and the plurality of sensors are electrically connected to the controller respectively. When pigs or staff enter the closed pig-driving passage 2, the sensors transmit signals to the controller, and the controller sends an opening or closing instruction to the air filtration system to realize automatic control of the air filtration system.

[0040] Embodiment 3

[0041] The difference between this embodiment and the first embodiment is that the controller is connected to the alarm, and the alarm can be an audible and visual alarm. When an outside vehicle or outsider enters the sensing area, the controller receives the signal from the sensor and sends a command to the alarm, and the alarm sends an alarm to drive away the outside vehicle or outsider. The controller also transmits the alarm signal to the computer terminal or handheld terminal of the staff through the wireless network.
