Description

Technical Field

[0001] This utility model relates to the field of duck breeding, specifically a ventilation device for the prevention and control of diseases in ducks. Background Technology

[0002] In the process of raising breeding ducks, due to the high stocking density of breeding ducks in pens, the virus spreads rapidly. Ventilation and disinfection are extremely important, which can greatly reduce the number of viruses in the breeding environment and effectively prevent the occurrence of diseases such as duck plague. However, the existing ventilation equipment has fixed air vents, which have dead corners, and disinfection operations require manual spraying, resulting in low disinfection efficiency.

[0003] The prior art discloses a disinfectant spraying device for duck breeding sheds, which automatically sprays disinfectant without the need for manual spraying. This not only improves the efficiency of disinfection inside the sheds but also avoids creating a large number of disinfection dead zones. It also makes the disinfectant droplets sprayed by the nozzle assembly finer and cover a wider area. However, this solution has the problems of a large coverage area and high construction cost. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model adopts a ventilation device for the prevention and control of diseases in breeding ducks, which solves the problem of low efficiency in ventilation and disinfection in existing breeding.

[0005] The technical solution is a ventilation device for the prevention and control of diseases in breeding ducks, including a shell with an air inlet chamber inside. An air inlet is located at the right end of the air inlet chamber, and air outlets are located at the front and rear ends of the air inlet chamber. An air outlet pipe is fixed to the outside of each air outlet. One end of the air outlet pipe is connected to the air outlet and the other end is open to the left. A vertical shaft is fixed in the middle of the air inlet chamber, and a rotating block is rotatably connected to the vertical shaft. A vertical plate is fixed on the front and rear sides of the rotating block, and the two vertical plates can alternately block the air outlets. A medicine box is fixed to the left end of the shell, and a liquid outlet pipe is provided at the front and rear ends of the medicine box. The outer end of the liquid outlet pipe extends into the air outlet pipe and is fixed with an atomizing nozzle.

[0006] The front and rear ends of the air inlet cavity are arc surfaces coaxial with the vertical axis. The air outlet is located on the arc surface. When the vertical plate rotates with the rotating block, the outer edge surface is in contact with the arc surface of the air inlet cavity, and the upper and lower end surfaces are in contact with the upper and lower side walls of the air inlet cavity. When one of the vertical plates rotates to a direction perpendicular to the air inlet axis, its outer end is located on the right side of the air outlet, and the outer end of the other vertical plate is located on the left side of the air outlet.

[0007] A generator is fixed to the right end of each of the aforementioned air outlet pipes. The generator shaft passes through the air outlet pipe and is fixedly connected to a fan. Electromagnets are fixed at the front and rear ends of the air inlet at the right side of the air outlet. The positive and negative poles of the electromagnets are connected to the positive and negative poles of the generator, respectively. The vertical plate is made of iron. When the airflow passes through the fan, it can drive the generator shaft to rotate and generate electricity, thereby causing the electromagnet to generate a magnetic field that attracts the vertical plate on the same side.

[0008] The liquid container has an inlet at the top.

[0009] The medicine box cavity is equipped with a water pump, and the liquid outlet pipes on both the front and rear sides are connected to the water pump.

[0010] This utility model has the following advantages over the prior art:

[0011] 1. This utility model uses two vertical plates to alternately open and close the air outlets on the front and rear sides, allowing airflow to be discharged alternately from the air outlet pipes on the front and rear sides. Each opening and closing of the air outlet by the vertical plates can linearly increase or decrease the airflow speed, providing different horizontal initial velocities to the liquid medicine sprayed by the atomizing nozzle, so that the atomized liquid medicine can be evenly sprayed at different distances from the air outlet pipe opening, greatly improving the spraying efficiency and coverage area of ​​the liquid medicine.

[0012] 2. This utility model uses airflow passing through the air outlet pipe to drive the fan to rotate, which in turn causes the generator to generate electricity for the electromagnet, thereby attracting the iron vertical plate on the same side to move to the right, providing a power source for the movement of the vertical plate. No external power source is required, which greatly reduces subsequent costs. Attached Figure Description

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figures 1 to 4The present invention includes a housing 1, an air inlet 2 inside the housing 1, an air inlet 3 at the right end of the air inlet 2, and air outlets 4 at the front and rear ends of the air inlet 2. An air outlet pipe 5 is fixed to the outside of each air outlet 4. One end of the air outlet pipe 5 is connected to the air outlet 4 and the other end is open to the left. A vertical shaft 6 is fixed in the middle of the air inlet 2. A rotating block 7 is rotatably connected to the vertical shaft 6. A vertical plate 8 is fixed on the front and rear sides of the rotating block 7. The two vertical plates 8 can alternately block the air outlet 4. A medicine box 9 is fixed to the left end of the housing 1. A liquid outlet pipe 10 is provided at the front and rear ends of the medicine box 9. The outer end of the liquid outlet pipe 10 passes through the air outlet pipe 5 and is fixed with an atomizing nozzle 11.

[0019] The front and rear end faces of the air inlet cavity 2 are arc surfaces coaxial with the vertical axis 6. The air outlet 4 is located on the arc surface. When the vertical plate 8 rotates with the rotating block 7, the outer edge surface is in contact with the arc surface of the air inlet cavity 2, and the upper and lower end faces are in contact with the upper and lower side walls of the air inlet cavity. When one of the vertical plates 8 rotates to a position perpendicular to the axis of the air inlet 3, its outer end is located on the right side of the air outlet 4, and the outer end of the other vertical plate 8 is located on the left side of the air outlet 4.

[0020] A generator 12 is fixed to the right end of each of the aforementioned air outlet pipes 5. The shaft of the generator 12 passes through the air outlet pipe 5 and is fixedly connected to a fan 13. Electromagnets 14 are fixed at the front and rear ends of the air inlet 2 at the right side of the air outlet 4. The positive and negative poles of the electromagnets 14 are connected to the positive and negative poles of the generator 12, respectively. The vertical plate 8 is made of iron. When the airflow passes through the fan 13, it can drive the shaft of the generator 12 to rotate and generate electricity, thereby causing the electromagnets 14 to generate a magnetic field that attracts the vertical plate 8 on the same side.

[0021] The liquid medicine box 9 has an inlet 15 at the top, allowing the operator to add liquid medicine into the liquid medicine box 9 through the inlet 15.

[0022] The medicine box 9 is equipped with a water pump, and the outlet pipes 10 on both the front and rear sides are connected to the water pump. The water pump can pump the medicine in the medicine box 9 out of the outlet pipes 10.

[0023] In use, this invention first connects the air inlet 3 to the fan, and the left end of the air outlet 5 faces the inside of the farm. Then, the disinfectant is filled into the medicine box 9 through the liquid inlet 15. The fan continuously delivers air from outside the farm into the air inlet 2. The airflow is blown into the farm through the air outlet 4 and the vertical pipe 5 on one side. The airflow through the vertical pipe 5 drives the generator 12 shaft to rotate and generate electricity through the fan 13. The current generates a magnetic field at the fixed position of the electromagnet 14, attracting the vertical plate 8 on the same side to a direction perpendicular to the axis of the air inlet 4. At this time, the vertical plate 8 can block the air outlet 4 on that side, while the outer end of the vertical plate 8 on the other side is located to the left of the air outlet 4. The airflow can enter the air outlet 4 on the other side without obstruction and be discharged along the left end of the air outlet 5. Since there is no more airflow through the blocked end of the air outlet 5, the generator 12 is de-energized. As the magnetism of electromagnet 14 gradually disappears, the generator 12 on the other side is driven by fan 13 to generate electricity, causing electromagnet 14 to become charged and attract vertical plate 8. This allows the two vertical plates 8 to rotate around vertical axis 6 again. The vertical plate 8 at the blocked end opens air outlet 4, while the vertical plate 8 at the outlet end blocks air outlet 4, allowing airflow to be blown out through air outlet pipe 5 on the other side. Then, the airflow drives the fan on that side to rotate again, repeating the above process to achieve alternating airflow from air outlet pipe 5 on both sides. When the airflow passes through atomizing nozzle 11, it can carry the atomized medicine into the breeding farm for spraying. Since each time the vertical plate 8 opens and closes air outlet 4, the air outlet 4 is gradually opened or closed, and the gas flow through air outlet pipe 5 gradually increases or decreases, the horizontal initial velocity provided by the airflow to the atomized medicine is constantly changed, allowing the medicine to be sprayed evenly at different locations near and far from the opening of air outlet pipe 5.

[0024] This invention uses two vertical plates 8 to alternately open and close the air outlets 4 on the front and rear sides, allowing airflow to be discharged alternately from the air outlet pipes 5 on the front and rear sides. Each opening and closing of the air outlets 4 by the vertical plates 8 causes the airflow velocity to increase or decrease linearly, providing different initial horizontal velocities to the liquid medicine sprayed by the atomizing nozzle 11. This allows the atomized liquid medicine to be sprayed evenly at different distances from the air outlet pipe 5, greatly improving the spraying efficiency and coverage area of ​​the liquid medicine. This invention also uses the airflow passing through the air outlet pipe 5 to drive the fan 13 to rotate, which causes the generator 12 to generate electricity for the electromagnet 14, thereby attracting the iron vertical plate 8 on the same side to move to the right, providing a power source for the movement of the vertical plate 8. No external power source is required, which greatly reduces subsequent costs.
