Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of livestock and poultry breeding, and particularly relates to a livestock and poultry house exhaust method. BACKGROUND

[0002] In the technical field of livestock and poultry breeding, the function of a ventilation system is to provide fresh air for livestock and poultry in a livestock and poultry house, so that the livestock and poultry house maintains appropriate air quality, while harmful gases, dust and moisture are discharged to ensure the health of the living environment of the livestock and poultry, and thus provide a healthy growth environment for the livestock and poultry.

[0003] At present, the livestock and poultry house on the market is generally provided with an air inlet and an air outlet. The air inlet is located at the top of the livestock and poultry house, and air is introduced through the air inlet to achieve ventilation inside the livestock and poultry house. The air outlet is located at the side of the livestock and poultry house, and air inside the livestock and poultry house is discharged through the air outlet to achieve exhaust, thereby achieving the effect of ventilation and air exchange. However, in the case that the air inlet is located at the top, the airflow introduced from the air inlet flows from top to bottom, forcing the air inside the livestock and poultry house to also flow from top to bottom. The air at each part of the livestock and poultry house cannot be discharged in time through the air outlet located at the side, and there is a problem of uneven exhaust, which leads to a large difference in temperature, carbon dioxide content, humidity and oxygen content at each part of the livestock and poultry house, affecting the healthy growth of the livestock and poultry. SUMMARY

The control device receives the detection information of the gas pressure sensor and compares it with the set pressure value preset on the control device. If the comparison value is positive, the control device controls the corresponding adjusting structure to reduce the opening of the corresponding first communication port. If the comparison value is negative, the control device controls the corresponding adjusting structure to increase the opening of the corresponding first communication port.

[0011] In an embodiment, an air inlet is arranged on the top of the livestock and poultry house body, and is connected to the livestock and poultry breeding room and the outside. External air flows into the air inlet and flows downward in the livestock and poultry breeding room. The original air in the livestock and poultry breeding room is forced to sink by the downward air flow, and the sunk air is discharged through the first communication port.

[0012] In an embodiment, the livestock and poultry house body further comprises:

[0013] a second driving mechanism;

[0014] a wind shield arranged in the livestock and poultry breeding room, the wind shield and the air inlet are arranged in parallel, the wind shield is connected to the second driving mechanism, and the wind shield is driven by the second driving mechanism to move towards or away from the air inlet;

[0015] When the wind shield is away from the air inlet, two second communication ports are formed between the wind shield and the air inlet. The two second communication ports are arranged on both sides of the width direction of the wind shield. The second communication ports are connected to the air inlet and the livestock and poultry breeding room, and the distance between the wind shield and the air inlet is adjustable to adjust the opening size of the second communication ports.

[0016] In an embodiment, a gas temperature sensor is arranged in the livestock and poultry breeding room, and is electrically connected to the control device. The control device receives the detection information of the gas temperature sensor and controls the exhaust device and the second driving mechanism to act according to the predetermined program based on the detection information.

[0017] In an embodiment, a humidity sensor is arranged in the livestock and poultry breeding room, the humidity sensor is electrically connected with the control device, the control device receives detection information of the humidity sensor and controls the exhaust device and the second driving mechanism according to a predetermined program based on the detection information.

[0018] In an embodiment, an oxygen concentration sensor is arranged in the livestock and poultry breeding room, the oxygen concentration sensor is electrically connected with the control device, the control device receives detection information of the oxygen concentration sensor and controls the exhaust device and the second driving mechanism according to a predetermined program based on the detection information.

[0019] In an embodiment, the exhaust cavity is configured as at least two exhaust sections, the at least two exhaust sections are arranged in sequence along the transverse direction of the exhaust duct and connected in sequence at the head and tail ends.

[0020] Among the at least two exhaust sections, the tail end of one exhaust section at the tail end is in communication with the air outlet.

[0021] Among the two adjacent exhaust sections, the capacity of one exhaust section closer to the air outlet is greater than that of the other exhaust section.

[0022] In an embodiment, among the at least two exhaust sections, the capacity of the exhaust section at the tail end is the sum of the capacities of the remaining exhaust sections.

[0023] In an embodiment, the number of the exhaust ducts is multiple, the exhaust ducts are arranged along the first transverse direction of the livestock and poultry house body, and the multiple exhaust ducts are arranged in sequence along the second transverse direction of the livestock and poultry house body.

[0024] The number of the exhaust devices is multiple, each exhaust device is arranged at a corresponding position of the air outlet of the corresponding exhaust duct.

[0025] In an embodiment, the exhaust duct is arranged in the foundation of the livestock and poultry house body, and the exhaust duct is made of concrete material.

[0026] The above technical solutions have at least the following advantages or beneficial effects:

[0027] The livestock and poultry house exhaust method of the present application can reduce the number of air outlets, and thus the number of exhaust devices, facilitate maintenance, and reduce costs, by realizing the communication between the multiple first communication openings and the air outlets through the exhaust cavity. Since the negative pressure at the first communication opening closer to the air outlet is greater than that at the other first communication openings, each air pressure sensor detects the pressure at the corresponding first communication opening in real time. Meanwhile, the control device receives the detection information from the air pressure sensor and compares it with the set pressure value preset on the control device. If the comparison value is positive, i.e., the pressure at the corresponding first communication opening is greater than the set pressure value, the control device controls the corresponding adjustment structure to reduce the opening degree of the corresponding first communication opening. In the case of a large flow rate (the greater the negative pressure, the greater the flow rate), a small opening degree of the first communication opening is conducive to reducing the amount of air flowing out through the first communication opening each time. If the comparison value is negative, i.e., the pressure at the corresponding first communication opening is less than the set pressure value, the control device controls the corresponding adjustment structure to increase the opening degree of the corresponding first communication opening. In the case of a small flow rate (the smaller the negative pressure, the smaller the flow rate), a large opening degree of the first communication opening is conducive to increasing the amount of air flowing out through the first communication opening each time. Thus, the amount of air exhausted through each first communication opening in the same time approaches or tends to be the same, i.e., the exhaust amount of each part in the livestock and poultry breeding room approaches or tends to be the same, the exhaust is more uniform, and the differences in temperature, carbon dioxide content, humidity, oxygen content, etc. in each part of the livestock and poultry breeding room are reduced, thereby reducing the disease rate of livestock and poultry and promoting the healthy growth of livestock and poultry.

DETAILED DESCRIPTION

[0043] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0044] Referring to Figures 1-11 , the livestock and poultry house main body 1 in the application is shown, the application provides a livestock and poultry house exhaust method, including the following steps:

[0045] The air exhaust duct 2 is arranged on the livestock and poultry house body 1, and is arranged horizontally on the bottom of the livestock and poultry house body 1 and below the livestock and poultry breeding room 11 of the livestock and poultry house body 1. The first communication port 22, the air exhaust cavity 21 and the air outlet 23 are arranged on the air exhaust duct 2. The first communication port 22 is arranged in multiple numbers, and the multiple first communication ports 22 are arranged in sequence along the transverse direction of the air exhaust duct 2 and extend from one end to the other end of the livestock and poultry breeding room 11. The first communication port 22 communicates the livestock and poultry breeding room 11 and the air exhaust cavity 21. The air outlet 23 is arranged on one end of the air exhaust duct 2, and the air outlet 23 communicates the air exhaust cavity 21 and the outside;

[0046] The air exhaust device 3 is arranged on the side close to the air outlet 23. The air exhaust device 3 is configured to guide the air in the air exhaust cavity 21 to be exhausted to the outside through the air outlet 23;

[0047] A plurality of adjusting structures 4 are arranged on the livestock and poultry house body 1. Each adjusting structure 4 is arranged near the corresponding first communication port 22. The adjusting structure 4 is configured to control the opening size of the first communication port 22;

[0048] An air pressure sensor is arranged near each first communication port 22. The air pressure sensor is configured to detect the pressure at the corresponding first communication port 22;

[0049] A control device is arranged on the livestock and poultry house body 1. The control device is electrically connected to the air exhaust device 3, the adjusting structure 4 and the air pressure sensor. The control device receives the detection information of the air pressure sensor and compares the detection information with the set pressure value preset on the control device. When the comparison value is positive, the control device controls the corresponding adjusting structure 4 to reduce the opening of the corresponding first communication port 22. When the comparison value is negative, the control device controls the corresponding adjusting structure 4 to increase the opening of the corresponding first communication port 22.

[0050] The livestock and poultry house exhaust method of the present application can reduce the number of air outlets 23 by realizing the communication between the plurality of first communication ports 22 and the air outlets 23 through the exhaust cavity 21, thereby reducing the number of exhaust devices 3, facilitating maintenance, and reducing costs. Since the negative pressure at the first communication port 22 closer to the air outlet 23 is greater than that at the remaining first communication ports 22, each air pressure sensor is used to detect the pressure at each corresponding first communication port 22 in real time. At the same time, the control device receives the detection information from the air pressure sensor and compares it with the set pressure value preset on the control device. If the comparison value is positive, that is, the pressure at the corresponding first communication port 22 is greater than the set pressure value, the control device controls the corresponding adjustment structure 4 to reduce the opening of the corresponding first communication port 22. In the case of a large flow rate (the greater the negative pressure, the greater the flow rate), a small opening of the first communication port 22 is beneficial to reducing the amount of air flowing out of the first communication port 22 each time. If the comparison value is negative, that is, the pressure at the corresponding first communication port 22 is less than the set pressure value, the control device controls the corresponding adjustment structure 4 to increase the opening of the corresponding first communication port 22. In the case of a small flow rate (the smaller the negative pressure, the smaller the flow rate), a large opening of the first communication port 22 is beneficial to increasing the amount of air flowing out of the first communication port 22 each time. Thus, the amount of air exhausted through each first communication port 22 in the same time approaches or tends to be the same, that is, the exhaust amount of each part in the livestock and poultry breeding room 11 approaches or tends to be the same, the exhaust is more uniform, and the differences in temperature, carbon dioxide content, humidity, oxygen content, etc. in each part of the livestock and poultry breeding room 11 are reduced, thereby reducing the disease rate of livestock and poultry and promoting the healthy growth of livestock and poultry.

[0051] Referring to Figures 1-2 In an embodiment, an air inlet 12 is arranged on the top of the livestock and poultry house body 1. The air inlet 12 communicates the livestock and poultry breeding room 11 with the outside, allowing external air flow to flow in from the air inlet 12 and flow downward in the livestock and poultry breeding room 11, ensuring that the air flow can reach each part of the livestock and poultry breeding room 11, achieving uniform ventilation and avoiding ventilation dead angles. At the same time, the downward flowing air flow forces the original air in the livestock and poultry breeding room 11 to sink, and the sunk air is promptly exhausted through the first communication port 22, achieving more uniform exhaust and avoiding exhaust dead angles, thereby ensuring uniform exhaust ventilation effect and providing a better growth environment for livestock and poultry in the livestock and poultry breeding room 11.

[0052] Referring to Figures 1-2 and Figure 5 In an embodiment, the livestock and poultry house body 1 further comprises:

[0053] a second driving mechanism 5;

[0054] The baffle 6 is located in the livestock and poultry breeding room 11, the baffle 6 and the air inlet 12 are arranged in parallel, the baffle 6 is connected with the second driving mechanism 5, and the baffle 6 is driven by the second driving mechanism 5 to move towards the direction close to or away from the air inlet 12;

[0055] In the case that the baffle 6 is away from the air inlet 12, two second communication openings 13 are formed between the baffle 6 and the air inlet 12, the two second communication openings 13 are respectively arranged on the two sides of the width direction of the baffle 6, the second communication openings 13 communicate the air inlet 12 and the livestock and poultry breeding room 11, and the distance between the baffle 6 and the air inlet 12 is adjustable to adjust the opening size of the second communication openings 13. Since the baffle 6 and the air inlet 12 are arranged in parallel and the baffle 6 can be driven by the second driving mechanism 5 to move towards the direction close to or away from the air inlet 12, the baffle 6 can move in parallel relative to the air inlet 12. Thus, in the case that the baffle 6 is away from the air inlet 12, the two second communication openings 13 arranged on the two sides of the width direction of the baffle 6 can supply the air flow to blow to the livestock and poultry breeding room 11 along the direction perpendicular to the baffle 6. In the case that the opening of the second communication opening 13 is large, the air flow can also effectively avoid directly blowing to the livestock and poultry located at the position below the baffle 6, thereby effectively avoiding the livestock and poultry from being cold due to the direct blowing of the air flow, so as to reduce the disease of the livestock and poultry. In addition, since the opening size of the second communication opening 13 is adjustable, the air inlet amount can be adjusted, thereby the air inlet amount can be controlled according to the actual environment in the livestock and poultry breeding room 11, so as to ensure that the environment in the livestock and poultry breeding room 11 can reach the ideal state suitable for the growth of livestock and poultry.

[0056] In an embodiment, an air temperature sensor is arranged in the livestock and poultry breeding room 11, the air temperature sensor is electrically connected with the control device, the control device receives the detection information of the air temperature sensor and controls the operation of the exhaust device 3 and the second driving mechanism 5 according to the predetermined program. That is, after the control device receives the detection information of the air temperature sensor, the control device compares the detection information with the preset air temperature value. In the case that the comparison value is positive, that is, the air temperature in the livestock and poultry breeding room 11 is high, the control device controls the second driving mechanism 5 to increase the opening of the second communication opening 13 to increase the air inlet amount, and at the same time, the control device controls the exhaust device 3 to increase the power to increase the air exhaust amount, until the air temperature in the livestock and poultry breeding room 11 is suitable. Otherwise, the control device controls the second driving mechanism 5 to reduce the opening of the second communication opening 13 to reduce the air inlet amount, and at the same time, the control device controls the exhaust device 3 to reduce the power to reduce the air exhaust amount, until the air temperature in the livestock and poultry breeding room 11 is suitable. Thus, the air temperature in the livestock and poultry breeding room 11 can be automatically adjusted, the air temperature in the livestock and poultry breeding room 11 is prevented from being too high or too low, and the risk of disease of the livestock and poultry is greatly reduced.

[0057] In an embodiment, a humidity sensor is arranged in the livestock breeding room 11, the humidity sensor is electrically connected with the control device, the control device receives the detection information of the humidity sensor and controls the operation of the exhaust device 3 and the second driving mechanism 5 according to the predetermined program based on the detection information. That is, after the control device receives the detection information of the humidity sensor, the control device compares the detection information with the preset humidity value. If the comparison value is positive, that is, the humidity in the livestock breeding room 11 is high, the control device controls the second driving mechanism 5 to increase the opening degree of the second communication port 13 to increase the air intake amount, and controls the exhaust device 3 to increase the power to increase the air exhaust amount until the humidity in the livestock breeding room 11 is appropriate. Otherwise, the control device controls the second driving mechanism 5 to decrease the opening degree of the second communication port 13 to decrease the air intake amount, and controls the exhaust device 3 to decrease the power to decrease the air exhaust amount until the humidity in the livestock breeding room 11 is appropriate. In this way, the humidity in the livestock breeding room 11 is automatically adjusted to avoid too high or too low humidity, which greatly reduces the risk of livestock disease.

[0058] In an embodiment, an oxygen concentration sensor is arranged in the livestock breeding room 11, the oxygen concentration sensor is electrically connected with the control device, the control device receives the detection information of the oxygen concentration sensor and controls the operation of the exhaust device 3 and the second driving mechanism 5 according to the predetermined program based on the detection information. That is, after the control device receives the detection information of the oxygen sensor, the control device compares the detection information with the preset oxygen value. If the comparison value is positive, that is, the oxygen in the livestock breeding room 11 is high, the control device controls the second driving mechanism 5 to decrease the opening degree of the second communication port 13 to decrease the air intake amount, and controls the exhaust device 3 to decrease the power to decrease the air exhaust amount. Otherwise, the control device controls the second driving mechanism 5 to increase the opening degree of the second communication port 13 to increase the air intake amount, and controls the exhaust device 3 to increase the power to increase the air exhaust amount. In this way, the oxygen in the livestock breeding room 11 is automatically adjusted to ensure that the oxygen in the livestock breeding room 11 is sufficient, which greatly reduces the risk of livestock disease.

The arc-shaped cross section of the flow guide portion 6111 can change the flow direction of the air flow after blocking the air flow, so as to make the air flow flow towards the second communication port 13, thereby avoiding the air flow directly blowing livestock and poultry, and meanwhile, the arc-shaped cross section of the flow guide portion 6111 can reduce the energy loss of the air flow when blocking the air flow, so as to make the air flow maintain the required flow rate, thereby ensuring good ventilation effect.

[0060] Referring to Figure 10 In an embodiment, the flow guide portion 6111 includes a first flow guide segment 61111, the center of the first flow guide segment 61111 is located on the side close to the air inlet 12, that is, the first flow guide segment 61111 is a circular arc structure concave towards the air inlet 12, and the first flow guide segment 61111 is arranged towards the second communication port 13, so as to guide the air flow to the second communication port 13, and meanwhile, the first flow guide segment 61111 can reduce the energy loss of the air flow when blocking the air flow, so as to make the air flow maintain the required flow rate, thereby ensuring good ventilation effect.

[0061] Referring to Figure 10 In an embodiment, the flow guide portion 6111 further includes a second flow guide segment 61112, the second flow guide segment 61112 and the first flow guide segment 61111 are sequentially arranged along the width direction of the wind baffle 6, and the second flow guide segment 61112 is located outside the first flow guide segment 61111, the center of the second flow guide segment 61112 is located on the side away from the air inlet 12, that is, the second flow guide segment 61112 is an arc-shaped convex structure convex towards the air inlet 12, and the second flow guide segment 61112 is located below the second communication port 13, the second flow guide segment 61112 can also have good flow guiding effect, and meanwhile, the second flow guide segment 61112 can reduce the energy loss of the air flow when blocking the air flow, so as to make the air flow maintain the required flow rate, thereby ensuring good ventilation effect, in addition, the combination of the second flow guide segment 61112 and the first flow guide segment 61111 can on one hand enhance the structural strength of the wind baffle 6, so as to make the wind baffle 6 not easy to deform, thereby ensuring good wind blocking and flow guiding effect, and on the other hand, the combination of the second flow guide segment 61112 and the first flow guide segment 61111 can facilitate the processing and manufacturing of the wind baffle 6, thereby facilitating the reduction of the processing difficulty of the wind baffle 6, so as to reduce the processing cost.

[0062] In other embodiments, the flow guide portion 6111 is a planar structure, and the flow guide portion 6111 can also have wind blocking and flow guiding effect.

[0063] In other embodiments, the flow guide portion 6111 is a groove structure with a triangular cross section and concave towards the air inlet 12, and the flow guide portion 6111 can also have wind blocking and flow guiding effect.

[0064] Referring to Figures 10-11 In an embodiment, the number of the flow guide portions 6111 is two, and the two flow guide portions 6111 are arranged on both sides of the width direction of the wind baffle 6, and each of the flow guide portions 6111 guides the airflow to the corresponding second communication port 13. In this way, the airflow is uniformly guided to the corresponding second communication port 13 through the two flow guide portions 6111 on the same wind baffle 6, and then the airflow is uniformly distributed in the livestock and poultry house, improving the uniformity of ventilation.

[0065] Referring to Figures 10-11 In an embodiment, the two flow guide portions 6111 are symmetrically arranged along the width direction of the wind baffle 6, so that the airflow flows more uniformly to the second communication port 13, and the uniformity of ventilation in the livestock and poultry house is better.

[0066] Referring to Figures 10-11 In an embodiment, the wind baffle 6 comprises:

[0067] a top plate 611, wherein the top plate 611 is provided with a flow guide portion 6111;

[0068] a bottom plate 612, wherein the bottom plate 612 is connected with the top plate 611 and is arranged apart from the top plate 611, so that the wind baffle 6 is a hollow structure, the overall weight of the wind baffle 6 is reduced, the wind baffle 6 is convenient to carry and install, the installation difficulty is low, the installation is more convenient, and materials can be saved, thereby reducing the cost.

[0069] Referring to Figures 10-11 In an embodiment, the wind baffle 6 further comprises:

[0070] a plurality of vertical plates 613, wherein the vertical plates 613 are connected with the top plate 611 and the bottom plate 612 and are located between the top plate 611 and the bottom plate 612, and the plurality of vertical plates 613 are arranged apart along the width direction of the wind baffle 6. The arrangement of the vertical plate 613 plays a role in enhancing the connection reliability of the top plate 611 and the bottom plate 612, and also plays a role in strengthening the structural strength of the wind baffle 6, so that the wind baffle 6 is not easy to deform, thereby maintaining the reliable wind blocking and flow guiding effect of the wind baffle 6, and the structure is more reliable.

[0071] In other embodiments, the wind baffle 6 can also be a solid structure.

[0072] In an embodiment, the wind baffle 6 is made of plastic material. The wind baffle 6 made of plastic material has a light overall weight, is more convenient to carry and install, and is more convenient to install. At the same time, the wind baffle 6 made of plastic material has a lower cost, thereby further reducing the cost.

[0073] Referring to Figure 6 and Figure 8In an embodiment, the wind shield 6 comprises:

[0074] at least two wind shielding sections 61 arranged in sequence along the length direction of the wind shield 6;

[0075] a connecting head 62 arranged between and connecting together the adjacent two wind shielding sections 61. Since the wind shield 6 is composed of the at least two wind shielding sections 61 and the connecting head 62 connecting together the adjacent two wind shielding sections 61, the wind shield 6 is of a sectional structure. In the processing, the wind shielding sections 61 and the connecting head 62 are respectively prepared, and then assembled together. Compared with directly preparing a whole wind shield 6 with a relatively long length, the sectional wind shield 6 is easier to prepare, and is more convenient to process, carry and install. Meanwhile, by installing the wind shield 6 in the livestock and poultry house and oppositely arranging the air inlet 12, the wind shield 6 can be used to block and change the flow direction of the air flow entering from the air inlet 12, so as to prevent the air flow from directly blowing the livestock and poultry, thereby avoiding the livestock and poultry from being cold due to the direct blowing of the air flow, reducing the risk of disease of the livestock and poultry, and being more conducive to the healthy growth of the livestock and poultry.

[0076] In the related art, in order to reduce the number of air inlets 12 and ensure good ventilation effect, the air inlet 12 is generally arranged in a long strip structure, that is, the length dimension of the air inlet 12 is relatively large. Therefore, the wind shield 6 is also arranged in a long strip structure matching the air inlet 12.

[0077] Referring to Figure 9 In an embodiment, the connecting head 62 is provided with a connecting hole 621, the connecting hole 621 is inserted and matched with the end of the wind shielding section 61, so as to connect together the connecting head 62 and the wind shielding section 61.

[0078] The wind shield 6 further comprises:

[0079] a fastener (not shown in the figure) connecting together the connecting head 62 and the wind shielding section 61. In this way, the end of the wind shielding section 61 can be limited by using the connecting hole 621, so as to effectively prevent the end of the wind shielding section 61 from shaking relative to the connecting head 62, thereby improving the connection stability of the wind shielding section 61 and the connecting head 62, and finally improving the connection stability of the adjacent two wind shielding sections 61, and the structure is more reliable. In addition, the arrangement of the fastener can further reinforce the connection reliability of the connecting head 62 and the wind shielding section 61, and the structure is more reliable.

[0080] In an embodiment, the connecting hole 621 penetrates through the connecting head 62 in front and back;

[0081] One end of one of the adjacent two wind shielding sections 61 is inserted into one end of the connecting hole 621, and one end of the other is inserted into the other end of the connecting hole 621;

[0082] In the case that the connecting head 62 connects the two adjacent wind blocking sections 61, the end portions of the two adjacent wind blocking sections 61 close to each other abut. Among them, the connecting hole 621 penetrating through the connecting head 62 in front and back is lower in preparation difficulty, simpler in processing technology, and more material-saving, thereby being capable of reducing the cost, and the connecting hole 621 penetratingly arranged allows the end portions of the two adjacent wind blocking sections 61 close to each other to abut together, so that the two adjacent wind blocking sections 61 are abutted and arranged, thereby being capable of increasing the connection reliability of the two adjacent wind blocking sections 61, and the structure is higher in reliability.

[0083] In other embodiments, the connecting head 62 is provided with a connecting hole 621 at each end in the length direction, and the two connecting holes 621 at the two ends in the length direction of the connecting head 62 are separately arranged, and each connecting hole 621 is respectively inserted and matched with the end portion of the corresponding one wind blocking section 61.

[0084] In an embodiment, the connecting head 62 is provided with a rib plate 622 extending along the width direction of the connecting head 62.

[0085] In the case that the connecting head 62 connects the two adjacent wind blocking sections 61, the rib plate 622 is located between the two adjacent wind blocking sections 61. In this way, the rib plate 622 is used to increase the structural strength of the connecting head 62, so that the connecting head 62 is not easy to deform, thereby reliably connecting the two adjacent wind blocking sections 61 together, and the structure is higher in reliability.

[0086] In an embodiment, the cross-sectional shape of the connecting head 62 is the same as the cross-sectional shape of the wind blocking section 61, so that the connecting head 62 can also play a good wind blocking role, the number of rib plates 622 on the connecting head 62 is two, the two rib plates 622 are separately arranged on the two sides in the width direction of the connecting head 62, and each rib plate 622 is located on the first drainage section 61111 of the corresponding drainage portion 6111 on the connecting head 62.

[0087] Specifically, the fastener can be a rivet, a screw, a bolt, or the like connecting structure.

[0088] Referring to Figure 5 In an embodiment, the second driving mechanism 5 comprises:

[0089] The motor 51 is arranged on the livestock and poultry house body 1.

[0090] The traction rope 52 is arranged at one end of the output shaft of the motor 51.

[0091] At least two supports 53, the upper end of the support 53 is hinged with the livestock and poultry house body 1, the at least two supports 53 are arranged along the length direction of the wind shield 6, the support 53 is provided with a supporting part, the supporting part is provided with the wind shield 6 and supports the wind shield 6, the support 53 and the other end of the traction rope 52 are connected;

[0092] In the case of the motor 51 rotating forward, the output shaft rotates to wind the traction rope 52 thereon, the support 53 is pulled by the traction rope 52 to swing upward relative to the livestock and poultry house body 1, and the wind shield 6 moves toward the air inlet 12 along with the support 53;

[0093] In the case of the motor 51 rotating reversely, the output shaft rotates to release the traction rope 52, the support 53 is loosened by the traction rope 52 to swing downward relative to the livestock and poultry house body 1, and the wind shield 6 moves away from the air inlet 12 along with the support 53. In this way, the traction rope 52 can be wound or released by starting the motor 51. In the case of winding the traction rope 52, the at least two supports 53 can be driven by the traction rope 52, that is, the support 53 is turned upward, and the wind shield 6 moves upward in parallel during the turning of the support 53. In the case of releasing the traction rope 52, the at least two supports 53 can be driven by the traction rope 52 to turn downward, and the wind shield 6 moves downward in parallel during the turning of the support 53, so that the wind shield 6 can cover the air inlet 12 or adjust the opening size of the second communication port 13. The second driving mechanism 5 is simple in structure, low in maintenance cost, and can drive multiple wind shields 6 by setting a group of second driving mechanisms 5, so as to simplify the structure and reduce the cost, thereby greatly reducing the overall cost of the ventilation device.

[0094] Referring to Figure 2 In an embodiment, one of the livestock and poultry house body 1 and the wind shield 6 is provided with a sealing element 7, and the sealing element 7 is arranged around the air inlet 12. When the wind shield 6 covers the air inlet 12, the livestock and poultry house body 1 and the wind shield 6 press the sealing element 7 together to seal the air inlet 12. In this way, in the case of hot weather, the livestock and poultry house needs to use a wet curtain and another air inlet to realize air inlet. In this case, the above-mentioned air inlet 12 needs to be sealed to ensure that the air flow treated by the wet curtain can enter the designated position of the livestock and poultry breeding room 11. In addition, the sealing element 7 can also play a buffering role when the wind shield 6 covers the air inlet 12, so as to avoid hard contact between the wind shield 6 and the livestock and poultry house body 1 and damage to the wind shield 6 and the livestock and poultry house body 1.

[0095] In an embodiment, the sealing element 7 is arranged on the livestock and poultry house body 1 to reduce the weight of the wind shield 6 and further reduce the weight of the second driving mechanism 5.

Under the premise that only one air outlet 23 is arranged on the air exhausting duct 2, by setting the capacity of one of the adjacent two air exhausting sections 211 in the same air exhausting cavity 21 closer to the air outlet 23 to be greater than that of the other, the capacity of the air exhausting section 211 closer to the air outlet 23 is greater. In this way, under the condition that each air exhausting section 211 can simultaneously exhaust air, the air exhausting section 211 closer to the air outlet 23 has an appropriate capacity to accommodate the air exhausted from the air exhausting section 211 farther away from the air outlet 23, thereby ensuring that the original air in each part of the livestock and poultry breeding room 11 is timely exhausted, and the air is more uniformly exhausted.

Under this structure, the inner diameters of each part of the same air exhausting section 211 are equal, that is, the air exhausting section 211 is a constant-diameter structure, which has a lower processing difficulty, can improve the processing efficiency, and can also reduce the cost.
