[0009] The rotating door is provided with an ultraviolet irradiation mechanism, and the upper end of the enclosure is provided with a limiting mechanism for limiting the rotating door.

[0010] Preferably, the water inlet mechanism comprises a water injection pipe fixed to the U-shaped pipe and a first valve body arranged on the water injection pipe.

[0011] Notably, the water inlet mechanism directly interfaces with the U-shaped pipe through the water injection pipe, which can quickly access the sterilization and disinfection liquid or water, and cooperate with the first valve body to realize water inlet on-off and flow regulation, thereby avoiding problems such as excessive waste of sterilization and disinfection liquid or insufficient flow leading to insufficient spraying.

The third nozzle faces the inside of the enclosure, which can accurately disinfect the upper space of the breeding house and the inner wall of the enclosure. Multiple fourth nozzles are distributed on the side wall of the riser, which can cover the upper and lower middle areas around the rotating door, solving the limitation of traditional spraying that can only cover the horizontal area. It is especially effective in disinfecting the middle and lower spaces where beef cattle move frequently.

[0018] Preferably, the ultraviolet irradiation mechanism includes multiple third slots extending through one end of the revolving door, multiple fourth slots extending through one end of the revolving door, and ultraviolet lamps fixed to the upper and lower ends of the inner wall of the fourth slots.

[0022] Preferably, the limiting mechanism includes a first insertion hole at the upper end of the enclosure, a second insertion hole through the upper end of the top plate, and a U-shaped insertion rod inserted into the inner walls of both the first and second insertion holes.

[0023] It is worth noting that the U-shaped plug is inserted into both the first and second plug holes simultaneously. The double plug hole positioning achieves rigid fixation of the rotating door, resulting in high fixation strength. This effectively prevents the rotating door from being accidentally opened due to collisions with cattle or external wind. Furthermore, the combination structure of the plug hole and the plug is simple and easy to assemble and disassemble. Farmers only need to insert or remove the plug to complete the limiting and unlocking, resulting in high operational efficiency.

[0025] 1. This device works in concert with a rotating door, a first spraying mechanism, a second spraying mechanism, and an ultraviolet irradiation mechanism. The liquid is delivered to the first fixed pipe through a U-shaped tube and a flexible tube. The first fixed pipe supplies liquid to the vertically distributed first nozzles. The second nozzles of the first spraying mechanism horizontally cover the perimeter of the entrance and exit. The vertical pipe of the second spraying mechanism covers the middle and lower part and the third nozzles to eliminate dead corners in the space through the fourth nozzle. At the same time, the ultraviolet lamps physically disinfect through the explosion-proof glass, forming a dual disinfection effect. The rotating door can rotate around the first fixed pipe and is quickly fixed by the limiting mechanism. There is no need for manual hand-held equipment, which solves the problems of low efficiency and incomplete coverage of manual spraying.

[0026] 2. The first fixed pipe is rotatably installed on the first U-shaped block. The first nozzles on its side wall are vertically and equidistantly distributed along the rotating door and extend to the outside of the door. After the rotating door is pushed close to the wall and fixed by the limiting mechanism, the first nozzles can spray evenly along the height of the wall, covering the upper and lower areas of the wall. At the same time, the third nozzle of the second spraying mechanism faces the inside of the enclosure, which can simultaneously disinfect the inner wall of the enclosure, improving the disinfection efficiency.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] To address the problems of inconvenience in disinfecting cattle shed entrances and exits, difficulty in spraying walls, and low overall sterilization efficiency in existing technologies, the following technical solution is proposed. Please refer to [link / reference]. Figures 1-7 ;

[0037] A sterilization and disinfection device for beef cattle sheds includes a first base plate 1, a fence 2 fixed to the upper end of the first base plate 1, multiple fixed seats 3 fixed to the upper end of the fence 2, a U-shaped pipe 4 fixed to the inner wall of the multiple fixed seats 3, a water inlet mechanism fixed to the U-shaped pipe 4, two second valve bodies 7 set on the two water outlet ends of the U-shaped pipe 4, a water outlet mechanism set on the first base plate 1, a wastewater guide block 8 fixed to one end of the first base plate 1 for receiving wastewater from the water outlet mechanism, a first U-shaped block 9 fixed to the upper end of the first base plate 1, a first fixed pipe 11 rotatably installed on the upper and lower ends of the inner wall of the first U-shaped block 9, a rotating door 10 fixed to the side wall of the first fixed pipe 11, a first spraying mechanism and a second spraying mechanism fixed to the rotating door 10, wherein the water inlet end of the first spraying mechanism and the water outlet end of the first fixed pipe 11 are interconnected, and the water inlet end of the second spraying mechanism and the water outlet end of the first spraying mechanism are interconnected.

[0038] The inlet end of the first fixed pipe 11 is connected to one end of the hose 22, and the other end of the hose 22 is threaded onto the inner wall of one of the outlet ends of the U-shaped pipe 4. The other outlet end of the U-shaped pipe 4 can be connected to the U-shaped pipe 4 of another set of disinfection and sterilization devices to realize array expansion. The two second valve bodies 7 independently control the on / off state and flow rate of the corresponding outlet ends.

[0039] The second fixed pipe 13 and the first fixed pipe 11 are internally interconnected. Multiple first nozzles 12 are fixed to the side wall of the first fixed pipe 11. The first nozzles 12 are equidistantly distributed along the vertical direction of the rotating door 10. The water outlet end of the first nozzle 12 passes through the side wall of the rotating door 10 and extends to the outside of the rotating door 10.

[0040] The revolving door 10 is equipped with an ultraviolet irradiation mechanism, and the upper end of the enclosure 2 is equipped with a limiting mechanism for limiting the revolving door 10.

[0041] It should be noted that the hose 22 is a flexible tube, long enough to allow the rotating door 10 to rotate without affecting the connection. A sealing ring is provided at the penetration point between the first nozzle 12 and the rotating door 10. When the water outlet end of the first nozzle 12 passes through the side wall of the rotating door 10, a rubber sealing ring is provided at the gap between it and the through hole of the rotating door 10. The sealing ring is fitted on the outer wall of the first nozzle 12 and fits tightly against the inner wall of the through hole of the rotating door 10, which can effectively prevent the disinfectant from leaking from the through gap, ensure stable spraying pressure, and at the same time avoid the disinfectant residue in the gap causing bacterial growth.

[0042] In use, the disinfectant is pressurized by an external pump and connected to the water inlet mechanism through a pipe. The disinfectant flows into the U-shaped pipe 4. Then, the second valve 7 near the rotating door 10 is opened, and the disinfectant flows through the hose 22 into the first fixed pipe 11, and then into the first and second spraying mechanisms. This allows for disinfection of the area near the rotating door 10. In addition, since the rotating door 10 can rotate on the first U-shaped block 9, after the limiting mechanism is released, the rotating door 10 can be manually rotated to adjust the position of the first and second spraying mechanisms, thereby spraying disinfectant over a large area within the enclosure 2 and improving the efficiency of disinfectant spraying.

[0043] In this embodiment, specifically: the water inlet mechanism includes a water injection pipe 5 fixed to the U-shaped pipe 4 and a first valve body 6 disposed on the water injection pipe 5.

[0044] In this embodiment, specifically: the water outlet mechanism includes a second trough 20 opened at one end of the first base plate 1 near the wastewater guide block 8, a plurality of support blocks 21 fixed to the upper and lower end faces of the inner wall of the second trough 20, and a plurality of evenly distributed first troughs 19 opened through the upper end of the second trough 20.

[0045] In this embodiment, specifically: the first spraying mechanism includes a second fixed pipe 13 fixed to the horizontal direction of the rotating door 10 and a plurality of second nozzles 14 disposed on the second fixed pipe 13, and the water inlet end of the second fixed pipe 13 and the water outlet end of the first fixed pipe 11 are interconnected.

[0046] In this embodiment, specifically: the second spraying mechanism includes a top plate 15 fixed to the upper end of the rotating door 10, a second bottom plate 16 fixed to the lower end of the rotating door 10, a riser 17 fixed to both the top plate 15 and the second bottom plate 16, a plurality of fourth nozzles 32 fixed to the side wall of the riser 17, and a third nozzle 18 fixed to the upper end of the riser 17. The riser 17 has an inverted L-shaped structure, and the water outlet end of the third nozzle 18 faces the interior of the enclosure 2.

[0047] In this embodiment, specifically: the ultraviolet irradiation mechanism includes a plurality of third grooves 29 extending through one end of the rotating door 10, a plurality of fourth grooves 30 extending through one end of the rotating door 10, and ultraviolet lamps 31 fixed to the upper and lower ends of the inner wall of the fourth groove 30. The third grooves 29 and the fourth grooves 30 are distributed crosswise on the rotating door 10. Two explosion-proof glass panes are fixed to the inner wall of the fourth groove 30, and the ultraviolet lamps 31 are located between the two explosion-proof glass panes.

[0048] Example 1: In this example, the limiting mechanism specifically includes a second U-shaped block 23 fixed to the upper end of the enclosure 2, an elastic rope 24 fixed to the upper end of the second U-shaped block 23 at one end, and a collar 25 fixed to the other end of the elastic rope 24. The collar 25 is fitted onto the third nozzle 18. The limiting mechanism, by means of the elastic deformation of the elastic rope 24, allows the collar 25 to be easily fitted onto or detached from the third nozzle 18. The operation is simple and quick, and the farmers can complete the fixing and unlocking of the rotating gate 10 without the aid of any tools, thus improving work efficiency.

[0049] Example 2: In this example, the limiting mechanism specifically includes a first insertion hole 26 at the upper end of the enclosure 2, a second insertion hole 27 penetrating the upper end of the top plate 15, and a U-shaped rod 28 inserted into the inner walls of both the first and second insertion holes 26 and 27. The U-shaped rod 28 is inserted into both the first and second insertion holes 26 and 27, respectively. The double insertion hole positioning achieves rigid fixation of the rotating door 10, which has high fixing strength and can effectively prevent the rotating door 10 from being accidentally opened due to collisions with cattle or external wind, thus ensuring the safety of the disinfection process. Moreover, the cooperation structure of the first insertion hole 26, the second insertion hole 27, and the U-shaped rod 28 is simple. Farmers only need to insert and remove the U-shaped rod 28 to complete the limiting and unlocking of the rotating door 10, which is convenient and efficient.

[0050] Working principle: Before starting, the external pressurizing pump body is connected to the water injection pipe 5 of the device through a pipeline. Then, according to the disinfection requirements, the first valve body 6 on the water injection pipe 5 is opened, so that the disinfectant liquid pressurized by the pump body flows into the U-shaped pipe 4 fixed to the inner wall of multiple fixed seats 3 along the water injection pipe 5.

[0051] Next, the second valve body 7 on the side of the U-shaped tube 4 near the rotating door 10 is opened. The disinfectant in the U-shaped tube 4 is then transported through the hose 22 threaded to the inner wall of the outlet end of the U-shaped tube 4 to the first fixed tube 11, which is rotatably installed on the upper and lower ends of the inner wall of the first U-shaped block 9. Since the multiple first nozzles 12 fixed to the side wall of the first fixed tube 11 can be equidistantly distributed along the vertical direction of the rotating door 10, the outlet end of the first nozzle 12 passes through the side wall of the rotating door 10 and extends to the outside. The rubber sealing ring at the penetration point is fitted on the outer wall of the first nozzle 12 and fits tightly against the inner wall of the through hole of the rotating door 10, which can effectively prevent the liquid from leaking and ensure stable spraying pressure.

[0052] Part of the disinfectant in the first fixed pipe 11 is sprayed directly onto the vertical area outside the revolving door 10 through the first nozzle 12 on its side wall, while the other part flows into the second fixed pipe 13, which is connected to the inside of the first fixed pipe 11, and is sprayed onto the horizontal area around the entrance and exit of the revolving door 10 through multiple second nozzles 14 on the second fixed pipe 13.

[0053] At the same time, the disinfectant in the first fixed pipe 11 will also flow into the riser 17 in the second spraying mechanism which is connected to the water outlet of the first spraying mechanism. The third nozzle 18 at the upper end of the riser 17 faces the inside of the enclosure 2 and can disinfect the upper space of the breeding house and the inner wall of the enclosure 2. The multiple fourth nozzles 32 fixed to its side wall cover the upper and lower parts of the rotating door 10 and the middle and lower parts of the surrounding area.

[0054] While spraying disinfection, the ultraviolet irradiation mechanism at one end of the rotating door 10 is activated simultaneously. The ultraviolet lamps 31 fixed to the upper and lower ends of the inner wall of the fourth tank 30 physically disinfect the area inside the enclosure 2 through the two explosion-proof glass on the inner wall of the fourth tank 30. The fourth tank 30 and multiple third tanks 29 that are opened through one end of the rotating door 10 are distributed in a cross pattern. The third tanks 29 can realize the air circulation inside the enclosure 2 and avoid the accumulation of odors.

[0055] When it is necessary to expand the disinfection range, if the limiting mechanism of Embodiment 1 is used, the elastic deformation of the elastic rope 24 fixed to the upper end of the second U-shaped block 23 can cause the collar 25 at the other end of the elastic rope 24 to disengage from the third nozzle 18 to release the limitation on the rotating door 10. If the limiting mechanism of Embodiment 2 is used, the U-shaped rod 28 inserted into the inner wall of the first insertion hole 26 at the upper end of the enclosure 2 and the second insertion hole 27 at the upper end of the top plate 15 can be pulled out to release the limitation.

[0056] Then, manually push the rotating door 10 to rotate around the first fixed pipe 11 inside the first U-shaped block 9, thereby driving the first spraying mechanism, the second spraying mechanism and the ultraviolet irradiation mechanism to adjust their positions and expand the disinfection range;

[0057] Wastewater generated during the disinfection process flows into the second tank 20 through the first tank 19 evenly distributed at one end of the first base plate 1. The wastewater is then guided along the second tank 20 into the wastewater guide block 8 and finally discharged through the guide block 8.
