[0047] a base body 1, the base body 1 is provided with an inner cavity 11 and an air inlet 12, the air inlet 12 and the inner cavity 11 are communicated;

[0048] a driving mechanism 2, the driving mechanism 2 is arranged on the base body 1;

[0049] a baffle 3, the baffle 3 is located in the inner cavity 11, the baffle 3 and the air inlet 12 are arranged in parallel, the baffle 3 is connected with the driving mechanism 2, the baffle 3 is driven by the driving mechanism 2 and can move towards the direction close to or away from the air inlet 12, that is, the baffle 3 moves in parallel along the direction close to or away from the air inlet 12;

[0050] in the case that the baffle 3 is close to the air inlet 12, the baffle 3 can cover the air inlet 12 to close the air inlet 12;

[0051] in the case that the baffle 3 is away from the air inlet 12, two communication openings 13 are formed between the baffle 3 and the air inlet 12, the two communication openings 13 are arranged on both sides of the width direction of the baffle 3, the communication openings 13 communicate the air inlet 12 and the inner cavity 11, so that the air flow entering from the air inlet 12 and resisted by the baffle 3 can enter the inner cavity 11 through the communication openings 13.

[0052] The ventilation device of the present application, since the baffle 3 and the air inlet 12 are arranged in parallel and the baffle 3 can be driven by the driving mechanism 2 to move towards the direction close to or away from the air inlet 12, the baffle 3 can move in parallel relative to the air inlet 12, so that in the case that the baffle 3 is away from the air inlet 12, the two communication openings 13 arranged on both sides of the width direction of the baffle 3 can supply the air flow to blow to the inner cavity 11 along the direction perpendicular to the baffle 3, in the case that the opening of the communication opening 13 is large, it can also effectively avoid the air flow directly blowing to the livestock and poultry located at the position below or in front of the baffle 3, and further effectively avoid the case that the livestock and poultry are cold due to being directly blown by the air flow, so as to reduce the disease of the livestock and poultry.

[0053] In an embodiment, the driving mechanism 2 is also used for adjusting the opening size of the communication opening 13, so as to be able to adjust the air inlet amount, and further be able to control the air inlet amount according to the actual environment in the inner cavity 11, so as to ensure that the environment in the inner cavity 11 can reach the ideal state suitable for the growth of livestock and poultry.

[0054] Referring to 8- Figure 9In an embodiment, the wind baffle 3 is provided with a flow guide part 3111, the flow guide part 3111 is oppositely arranged with the air inlet 12, the cross section of the flow guide part 3111 is arc-shaped, the flow guide part 3111 is used for blocking the air flow entering from the air inlet 12 and guiding the air flow to the communication port 13. The flow guide part 3111 with the arc-shaped cross section can change the flow direction of the air flow after blocking the air flow, so as to make the air flow flow in the direction of the communication port 13, thereby avoiding the air flow directly blowing livestock and poultry, and at the same time, the flow guide part 3111 with the arc-shaped cross section 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.

[0055] Referring to Figure 8 In an embodiment, the flow guide part 3111 includes a first flow guide segment 31111, the center of the first flow guide segment 31111 is located on the side close to the air inlet 12, that is, the first flow guide segment 31111 is a circular arc structure recessed towards the air inlet 12, and the first flow guide segment 31111 is arranged towards the communication port 13 to guide the air flow to the communication port 13, and at the same time, the first flow guide segment 31111 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.

[0056] Referring to Figure 8 In an embodiment, the flow guide part 3111 further includes a second flow guide segment 31112, the second flow guide segment 31112 and the first flow guide segment 31111 are sequentially arranged along the width direction of the wind baffle 3, and the second flow guide segment 31112 is located on the outside of the first flow guide segment 31111, the center of the second flow guide segment 31112 is located on the side away from the air inlet 12, that is, the second flow guide segment 31112 is an arc-shaped protruding structure protruding towards the air inlet 12, and the second flow guide segment 31112 is located below the communication port 13, the second flow guide segment 31112 can also have good flow guiding effect, and at the same time, the second flow guide segment 31112 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 31112 and the first flow guide segment 31111 can on the one hand enhance the structural strength of the wind baffle 3, so that the wind baffle 3 is 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 31112 and the first flow guide segment 31111 can facilitate the processing and manufacturing of the wind baffle 3, thereby facilitating the reduction of the processing difficulty of the wind baffle 3, so as to reduce the processing cost.

[0057] In other embodiments, the flow guide part 3111 is a planar structure, and the flow guide part 3111 can also have wind blocking and flow guiding effect.

[0058] In other embodiments, the flow guide part 3111 is a groove structure with a triangular cross section and recessed towards the air inlet 12, and the flow guide part 3111 can also have wind blocking and flow guiding effect.

[0059] In an embodiment, the number of the flow guide portions 3111 is two, and the two flow guide portions 3111 are arranged on both sides of the width direction of the wind deflector 3, and each of the flow guide portions 3111 guides the airflow to the corresponding communication port 13. In this way, the airflow is uniformly guided to the corresponding communication port 13 through the two flow guide portions 3111 on the same wind deflector 3, and then the airflow is uniformly distributed in the livestock and poultry house, thereby improving the uniformity of ventilation.

[0060] In an embodiment, the two flow guide portions 3111 are symmetrically arranged along the width direction of the wind deflector 3, so that the airflow flows to the communication port 13 more uniformly, and the uniformity of ventilation in the livestock and poultry house is better.

[0061] Referring to Figures 8-9 In an embodiment, the wind deflector 3 comprises:

[0062] a top plate 311, wherein the top plate 311 is provided with a flow guide portion 3111;

[0063] a bottom plate 312, wherein the bottom plate 312 is connected with the top plate 311 and is arranged apart from the top plate 311, so that the wind deflector 3 is a hollow structure, the overall weight of the wind deflector 3 is reduced, the wind deflector 3 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.

[0064] Referring to Figures 8-9 In an embodiment, the wind deflector 3 further comprises:

[0065] a plurality of vertical plates 313, wherein the vertical plates 313 are connected with the top plate 311 and the bottom plate 312 and are located between the top plate 311 and the bottom plate 312, and the plurality of vertical plates 313 are arranged apart along the width direction of the wind deflector 3. The arrangement of the vertical plate 313 plays a role in enhancing the connection reliability of the top plate 311 and the bottom plate 312, and also plays a role in strengthening the structural strength of the wind deflector 3, so that the wind deflector 3 is not easy to deform, thereby maintaining the reliable wind deflection and flow guiding effect of the wind deflector 3, and the structural reliability is higher.

[0066] In other embodiments, the wind deflector 3 can also be a solid structure.

[0067] In an embodiment, the wind deflector 3 is made of plastic material. The overall weight of the wind deflector 3 made of plastic material is lighter, which is more convenient to carry and install, and the installation is more convenient. At the same time, the wind deflector 3 made of plastic material has lower cost, thereby further reducing the cost.

[0068] In an embodiment, the wind deflector 3 comprises:

[0069] at least two wind deflection sections 31, wherein the at least two wind deflection sections 31 are arranged in sequence along the length direction of the wind deflector 3;

[0070] The connecting head 32 is located between two adjacent wind-blocking sections 31 and splices the two adjacent wind-blocking sections 31 together. Since the wind shield 3 is composed of at least two wind-blocking sections 31 and the connecting head 32 that splices the two adjacent wind-blocking sections 31 together, the wind shield 3 has a segmented structure. In the process of manufacturing, the wind-blocking sections 31 and the connecting head 32 are respectively prepared, and then the wind-blocking sections 31 and the connecting head 32 are assembled together. Compared with directly preparing a whole wind shield 3 with a relatively long length, the segmented wind shield 3 is easier to manufacture and more convenient to process, transport and install. At the same time, by installing the wind shield 3 in the livestock and poultry house and oppositely arranging the air inlet 12, the wind shield 3 can be used to block and change the flow direction of the airflow entering from the air inlet 12, so as to prevent the airflow from directly blowing the livestock and poultry, thereby avoiding the livestock and poultry from being cold due to the direct blowing of the airflow, reducing the risk of disease of the livestock and poultry, and being more conducive to the healthy growth of the livestock and poultry.

[0071] 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 of the air inlet 12 is relatively large. Therefore, the wind shield 3 is also arranged in a long strip structure that is adapted to the air inlet 12.

[0072] Referring to Figure 7 In an embodiment, the connecting head 32 is provided with a connecting hole 321, and the connecting hole 321 is inserted and matched with the end of the wind-blocking section 31 to splice the connecting head 32 and the wind-blocking section 31 together.

[0073] The wind shield 3 further comprises:

[0074] A fastener (not shown in the figure) connects the connecting head 32 and the wind-blocking section 31 together. In this way, the end of the wind-blocking section 31 can be limited by the connecting hole 321 to effectively prevent the end of the wind-blocking section 31 from shaking relative to the connecting head 32, thereby improving the connection stability of the wind-blocking section 31 and the connecting head 32, ultimately improving the connection stability of the two adjacent wind-blocking sections 31, and having higher structural reliability. In addition, the arrangement of the fastener can further reinforce the connection reliability of the connecting head 32 and the wind-blocking section 31, and has higher structural reliability.

[0075] In an embodiment, the connecting hole 321 penetrates through the connecting head 32 from front to back;

[0076] One end of one of the two adjacent wind-blocking sections 31 is inserted into one end of the connecting hole 321, and one end of the other is inserted into the other end of the connecting hole 321;

[0077] In the case that the connecting head 32 connects two adjacent wind blocking sections 31, the ends of the two adjacent wind blocking sections 31 abut against each other. Among them, the connecting hole 321 penetrating through the connecting head 32 in front and back is lower in manufacturing difficulty, simpler in processing technology, and saves materials, thereby reducing the cost. Meanwhile, the connecting hole 321 penetratingly arranged allows the ends of the two adjacent wind blocking sections 31 to abut against each other, so that the two adjacent wind blocking sections 31 are abutted and arranged, thereby increasing the connection reliability of the two adjacent wind blocking sections 31 and improving the structural reliability.

[0078] In other embodiments, the connecting head 32 is provided with a connecting hole 321 at each end in the length direction, and the two connecting holes 321 at the two ends in the length direction of the connecting head 32 are separately arranged, and each connecting hole 321 is respectively inserted and matched with the end of the corresponding wind blocking section 31.

[0079] In an embodiment, the connecting head 32 is provided with a rib plate 322 extending along the width direction of the connecting head 32.

[0080] In the case that the connecting head 32 connects two adjacent wind blocking sections 31, the rib plate 322 is located between the two adjacent wind blocking sections 31. In this way, the rib plate 322 is used to increase the structural strength of the connecting head 32, so that the connecting head 32 is not easy to deform, thereby reliably connecting the two adjacent wind blocking sections 31 together and improving the structural reliability.

[0081] In an embodiment, the cross-sectional shape of the connecting head 32 is the same as that of the wind blocking section 31, so that the connecting head 32 can also play a good wind blocking role. The number of rib plates 322 on the connecting head 32 is two, and the two rib plates 322 are separately arranged on both sides of the width direction of the connecting head 32, and each rib plate 322 is located on the first drainage section 31111 of the corresponding drainage part 3111 on the connecting head 32.

[0082] Specifically, the fastener can be a rivet, a screw, a bolt, or the like.

[0083] Referring to Figure 1 In an embodiment, the air inlet 12 is located on the top of the base body 1. The air inlet 12 located on the top can supply air to flow through the communication port 13 into the top of the inner cavity 11, and the air flow located on the top of the inner cavity 11 sinks from top to bottom, so that each position of the inner cavity 11 can be ventilated, avoiding ventilation dead angle, and improving the ventilation effect.

[0084] Referring to Figure 3 In an embodiment, the driving mechanism 2 comprises:

[0085] The motor 21 is arranged on the base body 1.

[0086] A traction rope 22, one end of the traction rope 22 is arranged on the output shaft of the motor 21;

[0087] At least two supports 23, the upper end of the support 23 is hinged to the base body 1, the at least two supports 23 are arranged in a spaced apart manner along the length direction of the wind deflector 3, the support 23 is provided with a supporting portion, the supporting portion is provided for the wind deflector 3 to be transversely arranged and supported, and the other end of the traction rope 22 is connected to the support 23;

[0088] In the case of forward rotation of the motor 21, the output shaft rotates to wind the traction rope 22 thereon, the support 23 is pulled by the traction rope 22 to swing upward relative to the base body 1, and the wind deflector 3 moves toward the air inlet 12 along with the swinging of the support 23;

[0089] In the case of reverse rotation of the motor 21, the output shaft rotates to release the traction rope 22, the support 23 is loosened by the traction rope 22 to swing downward relative to the base body 1, and the wind deflector 3 moves away from the air inlet 12 along with the swinging of the support 23. In this way, the traction rope 22 can be wound or released by starting the motor 21, in the case of winding the traction rope 22, the at least two supports 23 can be driven by the traction rope 22, that is, the support 23 is turned upward, and in the process of turning the support 23 upward, the wind deflector 3 moves upward in parallel; in the case of releasing the traction rope 22, the at least two supports 23 can be driven by the traction rope 22 to turn downward, and in the process of turning the support 23 downward, the wind deflector 3 moves downward in parallel, so that the wind deflector 3 can cover the air inlet 12 or adjust the opening size of the communication port 13. The driving mechanism 2 is simple in structure, low in maintenance cost, and can drive multiple wind deflectors 3 by arranging a group of driving mechanisms 2, which can simplify the structure and reduce the cost, thereby greatly reducing the overall cost of the ventilation device.

[0090] In an embodiment, a winding device is arranged on the output shaft of the motor 21, and the traction rope 22 is connected to the winding device to reliably wind and release the traction rope 22.

[0091] Referring to Figures 1-2 In an embodiment, one of the base body 1 and the wind deflector 3 is provided with a sealing element 4, the sealing element 4 is arranged around the air inlet 12, and in the case of covering the air inlet 12 by the wind deflector 3, the base body 1 and the wind deflector 3 jointly press the sealing element 4 to seal the air inlet 12. In this way, in the case of relatively hot weather, the livestock house needs to use a wet curtain and another air inlet to realize air intake, in which 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 specified position of the inner cavity 11; in addition, the sealing element 4 can also play a buffering role when the wind deflector 3 covers the air inlet 12, avoiding hard contact between the wind deflector 3 and the base body 1 to cause damage to the wind deflector 3 and the base body 1.

[0092] In one embodiment, the sealing member 4 is arranged on the base 1 to reduce the weight of the wind shield 3, thereby reducing the load of the driving mechanism 2.

[0094] The livestock and poultry house according to the present application, due to the use of the ventilation device described above, can effectively prevent the wind flow from directly blowing to the livestock and poultry located at the position below or in front of the wind shield 3, thereby effectively preventing the livestock and poultry from being cold due to the direct blowing of the wind flow, so as to reduce the disease of the livestock and poultry, even in the case that the opening degree of the communication port 13 is large.

[0095] In one embodiment, the livestock and poultry house according to the present application further comprises a rain shielding structure 5, which is arranged above and spaced apart from the top of the base 1, and the projection of the rain shielding structure 5 can cover each air inlet 12 on the top of the base 1, so as to block the rainwater from entering the inner cavity 11 through the air inlet 12.
