[0002] Livestock and poultry farms are specialized places for the centralized raising of various livestock and poultry. They must meet environmental protection and epidemic prevention standards. Livestock and poultry farms are classified according to the type of livestock, such as cattle farms, pig farms, and chicken farms. Taking broiler farming as an example, due to the epidemic prevention and control requirements of broiler farms, strict disinfection is carried out when entering and leaving the farm. Personnel wear protective clothing and disinfect the soles of their shoes. Vehicles are disinfected through a misting channel. This multi-link control is used to block the introduction of pathogens, protect the health of the flock, and build a solid biosecurity defense line.

[0003] However, the existing technology has the following shortcomings: In order to strictly implement the epidemic prevention standards, an independent disinfection area is set up in the passageway to and from the house. However, because the breeding process requires the staff to stay in batches, the area where the staff gathers often overlaps with the disinfection coverage area. In addition, the airtightness of the space affects the airflow circulation, resulting in uneven settling of disinfectant in some corners or densely populated areas, forming disinfection blind spots, which poses certain risks to the disinfection effect.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0025] As attached Figure 1 To be continued Figure 4 Appendix Figure 6 To be continued Figure 7 As shown: This embodiment provides an intelligent zoned dynamic disinfection room for livestock and poultry farms, including an even number of modular tubes 1, connected by an integrated box 3. Each modular tube 1 is equipped with a closed door 2. An identification device 4 is fixed on the front surface of the integrated box 3. A drive roof 5 is installed above the integrated box 3. An even number of connecting bolts 6 are provided on the side wall of the drive roof 5. An inner cavity 11 is formed inside the modular tube 1. An auxiliary rotating support platform 12 is provided at the bottom of the inner cavity 11. A limit rotating frame 13 is provided on the lower surface of the auxiliary rotating support platform 12. A tube plate 14 is provided above the inner cavity 11. A water storage box 15 is fixed on the upper surface of the tube plate 14. A transmission gear 16 is installed in the center of the upper surface of the tube plate 14. An even number of sliding door rails 17 are installed on the outer wall of the modular tube 1. A magnetic strip 18 is fixed on the surface of the modular tube 1. An outer frame 51 is provided inside the drive roof 5. A drive assembly 52 is installed in the center of the outer frame 51. A transmission toothed belt 53 is connected to the drive assembly 52. A rotating shaft 111 is installed at the center of the inner cavity 11 of the cylinder. A three-section partition plate 112 is embedded in the rotating shaft 111, and a disinfection spray component 113 is arranged above the three-section partition plate 112. A frame 521 is arranged inside the drive assembly 52. ​​A motor mounting bracket 523 is installed below the frame 521. A motor 522 is fixed on the motor mounting bracket 523. A drive gear 524 is connected to the drive shaft of the motor 522. A loop-shaped tube 1131 is arranged inside the disinfection spray component 113. A mounting bracket 1132 is arranged above the loop-shaped tube 1131, and a spray atomizing box 1133 is installed below the loop-shaped tube 1131.

[0026] Furthermore, at least two modular connectors 1 are provided. They are cylindrical in shape and their side walls are snapped and fixed to the integrated box 3. They are then locked and reinforced by connecting bolts 6. After being fixed, they form a male-female partitioned entry or a one-way entry and exit.

[0027] Furthermore, the magnetic strip 18 is used for magnetic attraction of the closed door 2, so that after the identification device 4 identifies it, the closed door 2 cannot be opened again within 30 seconds, and the closed door 2 slides in conjunction with the sliding door track 17 when it is in motion.

[0028] Furthermore, the three-section partition plate 112 is fixed by a rotating shaft 111. One end of the rotating shaft 111 is assisted in rotating by the limiting rotating frame 13, and the other end is driven by the transmission gear 16 at the top to rotate slowly.

[0029] Furthermore, the outer frame 51 is fixed above the integrated box 3 and the modular connector 1 by welding to cover the drive component 52 and prevent it from being exposed.

[0030] Furthermore, the motor 522 is activated by the identification device 4 and then triggered after closing, thereby driving the transmission belt 53 to rotate slowly in conjunction with the transmission gear 16 to perform rotational work.

[0031] Furthermore, the loop pipe 1131 is in the shape of a three-quarter ring, with a spray atomizing box 1133 installed at the bottom of each section. The density of atomization increases as it gets closer to the outlet, thereby achieving multi-level disinfection.

[0032] The specific working principle is as follows: This invention assembles the modular connector 1 and the integrated box 3, with the modular connector 1 snapped into both sides of the integrated box 3. Then, the drive roof 5 and connecting bolt 6 are installed separately. The drive roof 5 drives the modular connector 1, while the connecting bolt 6 reinforces the integrated box 3 and the modular connector 1 and limits the side wall positioning of the drive roof 5. In use, after the identification device 4 identifies personnel information, it de-energizes its magnetic strip 18, allowing the closing door 2 to open and close in conjunction with the sliding door rail 17. Simultaneously, the integrated box 3 supplies disinfectant to the water storage box 15 above the cylinder plate 14, and simultaneously drives the motor 522 mounted in the center of the outer frame 51. Gear 524 drives the transmission belt 53 to slowly rotate the transmission gear 16, indirectly causing the rotating shaft 111 to move. With the independent partitioning of the three-section partition plate 112, the device is sprayed by the small, medium and large spray atomizing box 1133, achieving independent all-round disinfection. Finally, it exits from the slot of the modular connecting tube 1 inside the connected box 3 for subsequent disinfection. This allows each person to enter and exit independently, avoiding the overlap and deviation of disinfection coverage caused by the gathering of traditional workers, thus avoiding incomplete disinfection and blind spots. In addition, the rotation of the three-section partition plate also circulates the air, preventing the internal air from being affected by the airtightness of the space.

[0033] In light of the above, please continue to participate in the exhibition. Figure 5 Appendix Figure 8 As shown: The integrated box 3 has an outlet door slot 31 on its back, and a drip rack 32 connected to the front of the outlet door slot 31. An inner cavity 34 is formed inside the integrated box 3, and a control chamber 33 is installed in the inner cavity 34. An even number of shoe washing troughs 35 are installed on the surface of the inner cavity 34, and conduits 36 are connected to both the front and rear of each shoe washing trough 35. An installation cavity 331 is provided inside the control chamber 33, and a door 332 covers the front of the installation cavity 331. A controller 333 is installed inside the control chamber 33, and a water tank 334 is located below the controller 333. An even number of extraction pumps 335 are installed on the water tank 334, and a supply pipe and a cap 336 are provided on the water tank 334. One of the extraction pumps 335 is connected to an output pipe 337.

[0034] Furthermore, the exit door slot 31 is located on the back of the connected box 3 and forms the box cavity 34, allowing personnel who have completed independent disinfection to enter and exit the breeding area.

[0035] Furthermore, the boot washing trough 35 is mainly installed at the opening of the modular connecting tube 1, so that the soles of the boots can be directly disinfected after disinfection, thus preventing bacteria carried by the soles from being introduced into the breeding area.

[0036] Furthermore, the boot washing trough 35 is equipped with two conduits 36. One conduit 36 ​​is connected to the extraction pump 335, which is opened by a switch on the door 332 to allow the pump to extract disinfectant water. The other conduit 36 ​​directly discharges the wastewater from washing the boot soles into the drainage trough, thus avoiding the recycling of used disinfectant water and the growth of bacteria.

[0037] The specific working principle is as follows: This invention, by setting the outlet door slot 31 on the back of the connected box 3, directly connects to the breeding area. After disinfection inside the modular receiving tube 1, personnel need to stand in the shoe washing trough 35 set on the inner cavity 34 of the box, and then open the preset switch on the door 332. This allows one of the pumps 335 to adjust the proportion of disinfectant water in the water tank 334, so that it is introduced into the shoe washing trough 35 through one of the pipes 36 to clean and disinfect the soles of the shoes. The cleaning water is directly discharged into the drain trough through another pipe 36, avoiding the accumulation of disinfectant water, which would cause the disinfectant water to be recycled, reduce its disinfection effect, and cause bacteria to accumulate. Finally, after standing on the drip rack 32 to drip off the disinfectant water, personnel can enter the breeding area.
