Description

Technical Field

[0001] This application relates to the field of livestock and poultry breeding technology, and in particular to a livestock and poultry house with uniform ventilation. Background Technology

[0002] In the field of livestock and poultry breeding technology, the function of ventilation systems is to provide fresh air to livestock and poultry in livestock and poultry houses, so as to maintain suitable air quality, while expelling harmful gases, dust and moisture, ensuring the health of the living environment of livestock and poultry, and thus providing a healthy growth environment for livestock and poultry.

[0003] Currently, livestock and poultry houses on the market are generally equipped with air inlets and air outlets. The air inlets are located at the top of the livestock and poultry house, and the air outlets are located on the sides of the livestock and poultry house, and the air inside the livestock and poultry house is exhausted through the air outlets, thus achieving the effect of ventilation and air exchange. However, when the air inlet is located at the top, the airflow entering through 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 in different parts of the livestock and poultry house cannot be exhausted in time through the air outlets located on the sides, resulting in uneven ventilation. Summary of the Invention

[0004] This application provides a livestock and poultry house with uniform ventilation to solve the problems existing in related technologies. The technical solution is as follows:

[0005] This application provides a livestock and poultry house with uniform ventilation, comprising:

[0006] The main body of the livestock and poultry house includes a livestock and poultry breeding room and an air inlet. The air inlet is located on the top of the main body of the livestock and poultry house and above the livestock and poultry breeding room. The air inlet is connected to the livestock and poultry breeding room.

[0007] An exhaust duct is provided, which is horizontally installed at the bottom of the main body of the livestock and poultry house and located below the livestock and poultry breeding room. The exhaust duct has an exhaust cavity, a first connecting port, and an air outlet. The exhaust cavity extends laterally along the exhaust duct and from one end of the livestock and poultry breeding room to the other end. There are multiple first connecting ports, which are arranged sequentially along the lateral side of the exhaust duct. The first connecting ports connect the livestock and poultry breeding room and the exhaust cavity. The air outlet is located at the end of the exhaust duct and connects the exhaust cavity to the outside.

[0008] In one embodiment, the number of air outlets on the exhaust duct is one;

[0009] The exhaust chamber has at least two exhaust sections, and the at least two exhaust sections are arranged sequentially along the transverse direction of the exhaust duct and connected end to end in sequence.

[0010] In at least two of the exhaust sections, the tail end of the exhaust section located at the tail end is connected to the air outlet;

[0011] Of the two adjacent exhaust sections, the one closer to the air outlet has a larger capacity than the other.

[0012] In one embodiment, the capacity of the exhaust section located at the tail end of at least two exhaust sections is the sum of the capacities of the remaining exhaust sections.

[0013] In one embodiment, the livestock and poultry shed with uniform ventilation further includes:

[0014] An exhaust device is located outside the exhaust cavity and on the side near the air outlet. The exhaust device is used to guide the airflow in the exhaust cavity to the air outlet.

[0015] In one embodiment, the livestock and poultry shed with uniform ventilation further includes:

[0016] Multiple adjustment structures are provided, each of which is positioned corresponding to a position of a first connecting port. The adjustment structures are used to adjust the opening size of the first connecting port.

[0017] In one embodiment, the adjustment structure includes:

[0018] A door panel that can cover the first communication opening;

[0019] A first drive mechanism is connected to the door panel. The first drive mechanism is used to drive the door panel to move towards or away from the first connection opening, so as to adjust the opening size of the first connection opening.

[0020] In one embodiment, there are multiple exhaust ducts, which are arranged along the first transverse direction of the main body of the livestock and poultry house, and the multiple exhaust ducts are arranged alternately along the second transverse direction of the main body of the livestock and poultry house.

[0021] In one embodiment, the livestock and poultry shed with uniform ventilation further includes:

[0022] The second drive mechanism is located on the main body of the livestock and poultry house;

[0023] A wind deflector is located in the livestock and poultry breeding room. The wind deflector and the air inlet are arranged in parallel. The wind deflector is connected to the second drive mechanism. The wind deflector is driven by the second drive mechanism and can move towards or away from the air inlet.

[0024] When the wind deflector is far from the air inlet, the wind deflector and the air inlet form two second connecting ports. The two second connecting ports are located on both sides of the width direction of the wind deflector. The second connecting ports connect the air inlet and the livestock and poultry breeding room. The distance between the wind deflector and the air inlet is adjustable to adjust the opening size of the second connecting ports.

[0025] In one embodiment, the wind deflector is provided with a flow guide, which is disposed opposite to the air inlet. The cross-section of the flow guide is arc-shaped. The flow guide is used to block the airflow entering from the air inlet and to guide the airflow to the second connecting port.

[0026] In one embodiment, the second drive mechanism includes:

[0027] An electric motor is mounted on the main body of the livestock and poultry house;

[0028] A traction rope, one end of which is attached to the output shaft of the motor;

[0029] At least two supports are provided, the upper end of which is hinged to the main body of the livestock and poultry house. The at least two supports are arranged at intervals along the length of the wind deflector. Each support is provided with a support part, which allows the wind deflector to pass through laterally and supports the wind deflector. The other end of the support is connected to the traction rope.

[0030] When the motor is rotating in the forward direction, the output shaft rotates and winds the traction rope around it. The bracket is pulled by the traction rope and swings upward relative to the main body of the livestock and poultry house. The wind deflector moves towards the air inlet as the bracket swings.

[0031] When the motor rotates in the reverse direction, the output shaft rotates and releases the traction rope. The bracket swings downward relative to the main body of the livestock house due to the relaxation of the traction rope, and the wind deflector moves away from the air inlet as the bracket swings.

[0032] The advantages or beneficial effects of the above technical solutions include at least the following:

[0033] The livestock and poultry house of the present invention has an air inlet located at the top of the main body of the house, which allows external airflow to flow in and circulate from top to bottom within the livestock and poultry breeding room. This ensures that the airflow reaches all parts of the breeding room, achieving uniform ventilation and avoiding dead zones. Simultaneously, the downward airflow forces the existing air in the breeding room to sink, and the sunken air is promptly discharged through multiple first connecting openings located at the bottom of the breeding room. This results in more uniform exhaust, avoiding dead zones and ensuring a uniform ventilation effect, thus providing a better growth environment for the livestock and poultry. Furthermore, the exhaust chamber connects the multiple first connecting openings to the air outlets, reducing the number of air outlets. This also reduces the number of active exhaust devices needed near the air outlets, simplifying maintenance and lowering costs.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of this application will become readily apparent from the accompanying drawings and the following detailed description.

[0049] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0050] See Figures 1-11 This invention illustrates a preferred embodiment of a livestock and poultry shed capable of uniform ventilation, comprising:

[0051] The main body of the livestock and poultry house 1 has a livestock and poultry breeding room 11 and an air inlet 12. The air inlet 12 is located on the top of the main body of the livestock and poultry house 1 and above the livestock and poultry breeding room 11. The air inlet 12 is connected to the livestock and poultry breeding room 11 so that external airflow can flow in from the air inlet 12 and make the airflow flow from top to bottom in the livestock and poultry breeding room 11, ensuring that the airflow can reach all parts of the livestock and poultry breeding room 11, achieving uniform ventilation and avoiding ventilation dead corners.

[0052] The exhaust duct 2 is horizontally installed at the bottom of the main body 1 of the livestock and poultry house and below the livestock and poultry breeding room 11. The exhaust duct 2 has an exhaust cavity 21, a first connecting port 22 and an air outlet 23. The exhaust cavity 21 extends horizontally along the exhaust duct 2 and extends from one end of the livestock and poultry breeding room 11 to the other end. There are multiple first connecting ports 22, which are arranged sequentially along the horizontal direction of the exhaust duct 2. The first connecting port 22 connects the livestock and poultry breeding room 11 and the exhaust cavity 21. The air outlet 23 is located at the end of the exhaust duct 2 and connects the exhaust cavity 21 to the outside.

[0053] The livestock and poultry house of the present invention has an air inlet 12 located at the top of the main body 1, which allows external airflow to flow in and flow from top to bottom in the livestock and poultry breeding room 11. This ensures that the airflow reaches all parts of the livestock and poultry breeding room 11, achieving uniform ventilation and avoiding ventilation dead zones. At the same time, the downward airflow forces the original air in the livestock and poultry breeding room 11 to sink. The sunken air is then discharged in a timely manner through multiple first connecting ports 22 located below the livestock and poultry breeding room 11, resulting in more uniform exhaust and avoiding exhaust dead zones. This ensures uniform exhaust and ventilation, providing a better growth environment for the livestock and poultry in the breeding room 11. In addition, the exhaust cavity 21 connects the multiple first connecting ports 22 and the air outlets 23, reducing the number of air outlets 23. This reduces the number of active exhaust devices 3 that need to be added near the air outlets 23, making maintenance easier and reducing costs.

[0054] The main body of the livestock and poultry house 1 includes a foundation, a wall and a roof. The wall is located on the foundation and the roof is located on top of the wall. The foundation, wall and roof together form a livestock and poultry breeding room 11. The air inlet 12 is located on the roof and the exhaust pipe 2 is located in the foundation.

[0055] See Figure 3 In one embodiment, the number of air outlets 23 on the exhaust duct 2 is one;

[0056] The exhaust chamber 21 has at least two exhaust sections 211, which are arranged sequentially along the transverse side of the exhaust duct 2 and connected end to end.

[0057] In at least two exhaust sections 211, the tail end of the exhaust section 211 located at the end is connected to the air outlet 23, that is, the tail end of the exhaust section 211 closest to the air outlet 23 is connected to the air outlet 23.

[0058] In two adjacent exhaust sections 211, the one closer to the air outlet 23 has a larger capacity than the other. By setting only one air outlet 23 on the exhaust duct 2, the number of air outlets 23 can be further reduced. If an active exhaust device 3 needs to be added near the air outlet 23, the number of active exhaust devices 3 can be further reduced, making maintenance easier and further reducing costs. With only one air outlet 23 on the exhaust duct 2, by setting the capacity of the one closer to the air outlet 23 in two adjacent exhaust sections 211 in the same exhaust chamber 21 to be larger than the other, the exhaust section 211 closer to the air outlet 23 has a larger capacity. In this way, while ensuring that all exhaust sections 211 can exhaust air simultaneously, the exhaust section 211 closer to the air outlet 23 has an appropriate capacity to accommodate the air discharged from the exhaust section 211 farther away from the air outlet 23, thereby ensuring that the original air in all parts of the livestock and poultry breeding room 11 is discharged in a timely manner and the exhaust is more uniform.

[0059] See Figure 3 In one embodiment, in at least two exhaust sections 211, the capacity of the exhaust section 211 located at the tail end is the sum of the capacities of the other exhaust sections 211, so that the exhaust section 211 closer to the air outlet 23 has sufficient capacity to accommodate the air discharged from the exhaust section 211 further away from the air outlet 23, thereby ensuring that the original air in all parts of the livestock and poultry breeding room 11 is discharged in a timely manner and the exhaust is more uniform.

[0060] In one embodiment, the lateral lengths of each exhaust section 211 are equal. Among at least two exhaust sections 211, the inner diameter of the exhaust section 211 located at the tail end is the sum of the inner diameters of the other exhaust sections 211. Under this structure, the inner diameters at all parts of the same exhaust section 211 are equal, that is, the exhaust section 211 is a constant diameter structure, which makes the processing more difficult, improves processing efficiency, and reduces costs.

[0061] In one embodiment, the exhaust duct 2 is a structure made of concrete, which can be integrally formed with the foundation, making it easier to process, further improving processing efficiency and reducing costs. At the same time, the exhaust duct 2 made of concrete is not prone to aging and deformation, has a longer service life, and requires less maintenance.

[0062] In other embodiments, the exhaust duct 2 may also be a structure made of steel or plastic.

[0063] See Figure 3 In one embodiment, the livestock shed, which could otherwise provide uniform ventilation, further includes:

[0064] The exhaust device 3 is located outside the exhaust cavity 21 and on the side near the air outlet 23. The exhaust device 3 is used to guide the airflow in the exhaust cavity 21 to the outside of the air outlet 23 to accelerate the air flow, so that the original air in the livestock and poultry breeding room 11 can be smoothly discharged to the outside, and the exhaust is smoother, more uniform and timely.

[0065] In one embodiment, the exhaust device 3 may specifically be a fan or other negative pressure device.

[0066] See Figure 4 In one embodiment, the livestock shed, which could otherwise provide uniform ventilation, further includes:

[0067] Multiple adjustment structures 4 are provided, each corresponding to a first connecting port 22. The adjustment structures 4 are used to adjust the opening of the first connecting port 22 so that the opening of the first connecting port 22 is adjustable. In this way, since the negative pressure of the exhaust section 211 closer to the air outlet 23 is greater and the exhaust speed is faster, the opening of the first connecting port 22 closer to the air outlet 23 is adjusted to be smaller than the opening of the first connecting port 22 further away from the air outlet 23. This ensures that the amount of air discharged through each first connecting port 22 at the same time is close or tends to be the same, thereby making the exhaust of each part in the livestock and poultry breeding room 11 more uniform and ensuring that the environment of each part in the livestock and poultry breeding room 11 is similar.

[0068] In one embodiment, a pressure sensor (not shown in the figure) is provided near each of the first communication ports 22, and the pressure sensor is configured to detect the pressure at the corresponding first communication port 22.

[0069] A control device (not shown in the figure) is installed on the main body 1 of the livestock and poultry house. The control device is electrically connected to the exhaust device 3, the adjustment structure 4 and the air pressure sensor. The control device receives the detection information from the air pressure sensor and compares the detection information with the preset pressure value set on the control device. When the comparison value is positive, the control device controls the corresponding adjustment structure 4 to reduce the opening of the corresponding first connection port 22. When the comparison value is negative, the control device controls the corresponding adjustment structure 4 to increase the opening of the corresponding first connection port 22.

[0070] The pressure at each corresponding first connecting port 22 is detected in real time using various pressure sensors. Simultaneously, a control device receives the detection information from the pressure sensors and compares it with a preset pressure value. If the comparison value is positive (i.e., the pressure at the corresponding first connecting port 22 is greater than the preset pressure value), the control device controls the corresponding adjustment structure 4 to reduce the opening of the corresponding first connecting port 22. Under conditions of high flow velocity (higher negative pressure, higher flow velocity), a smaller opening of the first connecting port 22 helps reduce the amount of air flowing out each time. If the comparison value is negative (i.e., the pressure at the corresponding first connecting port 22 is greater than the preset pressure value), the control device controls the corresponding adjustment structure 4 to reduce the opening of the corresponding first connecting port 22. When the pressure at point 2 is lower than the set pressure value, the control device controls the corresponding adjustment structure 4 to increase the opening of the corresponding first connecting port 22. When the flow rate is low (the lower the negative pressure, the lower the flow rate), a larger opening of the first connecting port 22 is beneficial to increasing the amount of air flowing out of the first connecting port 22 each time. This makes the amount of air discharged through each first connecting port 22 close to or similar within the same time period. In other words, the exhaust volume of each part in the livestock and poultry breeding room 11 is close to or similar, and the exhaust is more uniform. This can reduce the differences in temperature, carbon dioxide content, humidity, oxygen content, etc. in each part of the livestock and poultry breeding room 11, thereby reducing the incidence of livestock and poultry diseases and promoting the healthy growth of livestock and poultry.

[0071] In other embodiments, the opening size of each first connection port 22 can also be manually controlled.

[0072] See Figure 4 In one embodiment, the adjustment structure 4 includes:

[0073] Door panel 41, door panel 41 can cover the first connecting port 22;

[0074] The first drive mechanism 42 is connected to the door panel 41. The first drive mechanism 42 drives the door panel 41 to move towards or away from the first connecting opening 22, thereby adjusting the opening size of the first connecting opening 22. Thus, by controlling the first drive mechanism 42, the movement of the door panel 41 can be manipulated, thereby adjusting the opening size of the first connecting opening 22, making operation convenient and adjustment more efficient.

[0075] See Figure 4 In one embodiment, the first drive mechanism 42 is used to drive the door panel 41 to move parallel to the first connecting port 22. That is, the first drive mechanism 42 is a linear drive mechanism. Under this structure, the opening and closing of the door panel 41 is more stable and smooth, and the structural reliability is higher.

[0076] In one embodiment, the first drive mechanism 42 is used to drive the door panel 41 to rotate relative to the first connecting port 22, that is, the first drive mechanism 42 is a rotary drive mechanism.

[0077] Specifically, the first drive mechanism 42 can be any one of a motor, cylinder, hydraulic cylinder, etc., or the first drive mechanism 42 can be a combination of a motor and other intermediate transmission mechanisms.

[0078] See Figure 3 In one embodiment, there are multiple exhaust ducts 2. The exhaust ducts 2 are arranged along the first transverse direction of the main body 1 of the livestock and poultry house, and the multiple exhaust ducts 2 are arranged at intervals along the second transverse direction of the main body 1 of the livestock and poultry house, so as to make the exhaust more uniform and further improve the ventilation effect.

[0079] See Figures 1-2 as well as Figure 5 In one embodiment, the livestock shed, which could otherwise provide uniform ventilation, further includes:

[0080] The second drive mechanism 5 is located on the main body 1 of the livestock and poultry house;

[0081] Wind deflector 6 is located in the livestock and poultry breeding room 11. Wind deflector 6 and air inlet 12 are arranged in parallel. Wind deflector 6 is connected to the second drive mechanism 5. Wind deflector 6 is driven by the second drive mechanism 5 and can move towards or away from air inlet 12.

[0082] When the wind deflector 6 is close to the air inlet 12, the wind deflector 6 can cover the air inlet 12;

[0083] When the wind deflector 6 is far away from the air inlet 12, the wind deflector 6 and the air inlet 12 form two second connecting ports 13. The two second connecting ports 13 are placed on both sides of the width direction of the wind deflector 6. The second connecting ports 13 connect the air inlet 12 and the livestock and poultry breeding room 11. The distance between the wind deflector 6 and the air inlet 12 is adjustable to adjust the opening size of the second connecting ports 13. Since the wind deflector 6 and the air inlet 12 are arranged in parallel and the wind deflector 6 can be driven by the second drive mechanism 5 to move towards or away from the air inlet 12, the wind deflector 6 can move parallel to the air inlet 12. Thus, when the wind deflector 6 is away from the air inlet 12, the two second connecting ports 13 located on both sides of the width direction of the wind deflector 6 can allow airflow to blow towards the livestock and poultry breeding room 11 in a direction perpendicular to the wind deflector 6. When the opening of the second connecting ports 13 is large, it can also effectively prevent the airflow from blowing directly onto the livestock and poultry located below the wind deflector 6, thereby effectively preventing the livestock and poultry from getting cold due to direct airflow and reducing the incidence of livestock and poultry diseases. In addition, since the opening of the second connecting ports 13 is adjustable, the air intake can be adjusted, and the air intake can be controlled according to the actual environment in the livestock and poultry breeding room 11 to ensure that the environment in the livestock and poultry breeding room 11 can reach an ideal state suitable for the growth of livestock and poultry.

[0084] See Figure 7 , Figure 9 as well as Figures 10-11 In one embodiment, the baffle plate 6 is provided with a flow guide 6111, which is disposed opposite to the air inlet 12. The cross-section of the flow guide 6111 is arc-shaped. The flow guide 6111 is used to block the airflow entering from the air inlet 12 and guide the airflow to the second connecting port 13. The arc-shaped flow guide 6111 can change the direction of the airflow after blocking the airflow, thereby causing the airflow to flow towards the direction of the second connecting port 13, avoiding the airflow blowing directly on livestock and poultry. At the same time, the arc-shaped flow guide 6111 can reduce the energy loss of the airflow when blocking the airflow, so that the airflow maintains the required flow rate, thereby ensuring a good ventilation effect.

[0085] See Figure 10 In one embodiment, the airflow guiding section 6111 includes a first airflow guiding section 61111, the center of which is located on the side near the air inlet 12. That is, the first airflow guiding section 61111 is an arc-shaped structure recessed towards the air inlet 12, and the first airflow guiding section 61111 is arranged towards the second connecting port 13 to guide the airflow to the second connecting port 13. At the same time, it can also reduce the energy loss of the airflow when blocking the airflow, so that the airflow maintains the required flow rate, thereby ensuring a good ventilation effect.

[0086] See Figure 10 In one embodiment, the drainage section 6111 further includes a second drainage section 61112. The second drainage section 61112 and the first drainage section 61111 are arranged sequentially along the width direction of the baffle plate 6, and the second drainage section 61112 is located outside the first drainage section 61111. The center of the second drainage section 61112 is located on the side away from the air inlet 12, that is, the second drainage section 61112 is an arc-shaped protrusion structure protruding towards the air inlet 12, and the second drainage section 61112 is located below the second connecting port 13. 61112 can also achieve a good airflow diversion effect. At the same time, it can reduce the energy loss of the airflow when blocking the airflow, so that the airflow can maintain the required flow rate, thereby ensuring a good ventilation effect. In addition, the combination of the second airflow diversion section 61112 and the first airflow diversion section 61111 can enhance the structural strength of the wind deflector 6, making the wind deflector 6 less prone to deformation, thereby ensuring a good wind deflection and airflow diversion effect. On the other hand, it can also facilitate the processing and manufacturing of the wind deflector 6, thereby reducing the processing difficulty of the wind deflector 6 and thus reducing the processing cost.

[0087] In other embodiments, the drainage portion 6111 has a planar structure, and this drainage portion 6111 can also achieve the effect of blocking wind and draining air.

[0088] In other embodiments, the drainage section 6111 is a groove structure with a triangular cross-section and recessed towards the air inlet 12. This drainage section 6111 can also achieve the effect of blocking and guiding the airflow.

[0089] See Figures 10-11 In one embodiment, there are two airflow guiding sections 6111, which are respectively placed on both sides of the width direction of the baffle plate 6. Each airflow guiding section 6111 directs the airflow to its corresponding second connecting port 13. In this way, the airflow is evenly guided to the corresponding second connecting port 13 by the two airflow guiding sections 6111 on the same baffle plate 6, thereby making the airflow evenly distributed in the livestock and poultry house and improving the uniformity of ventilation.

[0090] See Figures 10-11 In one embodiment, the two air intakes 6111 are symmetrically arranged along the width of the baffle plate 6 so that the airflow flows more evenly to the second connecting port 13, thereby improving the ventilation uniformity in the livestock and poultry house.

[0091] See Figures 10-11 In one embodiment, the wind deflector 6 includes:

[0092] Top plate 611, with a drainage section 6111 provided on top plate 611;

[0093] The base plate 612 is connected to and spaced apart from the top plate 611, making the wind deflector 6 a hollow structure. This reduces the overall weight of the wind deflector 6, making it easier to transport and install. The installation is simpler and more convenient, and it also saves materials, thereby reducing costs.

[0094] See Figures 10-11 In one embodiment, the wind deflector 6 further includes:

[0095] Multiple vertical plates 613 connect the top plate 611 and the bottom plate 612 and are located between the top plate 611 and the bottom plate 612. The multiple vertical plates 613 are arranged at intervals along the width direction of the wind deflector 6. The arrangement of these vertical plates 613 serves two purposes: firstly, it enhances the connection reliability between the top plate 611 and the bottom plate 612; secondly, it strengthens the structural strength of the wind deflector 6, making it less prone to deformation. This ensures that the wind deflector 6 maintains a reliable wind-blocking and air-draining effect, resulting in higher structural reliability.

[0096] In other embodiments, the wind deflector 6 may also be a solid structure.

[0097] In one embodiment, the wind deflector 6 is a structure made of plastic. The wind deflector 6 made of plastic is lightweight, making it easier to transport and install. It is also more convenient to install. At the same time, the wind deflector 6 made of plastic is less expensive, which helps to further reduce costs.

[0098] See Figure 6 as well as Figure 8 In one embodiment, the wind deflector 6 includes:

[0099] At least two windbreak sections 61 are arranged sequentially along the length of the windbreak plate 6;

[0100] A connector 62 is located between two adjacent windbreak sections 61 and splices the two adjacent windbreak sections 61 together. Since the windbreak panel 6 is composed of at least two windbreak sections 61 and a connector 62 that splices the two adjacent windbreak sections 61 together, the windbreak panel 6 has a segmented structure. During processing, the windbreak sections 61 and the connector 62 are prepared separately, and then the windbreak sections 61 and the connector 62 are assembled together. Compared with directly preparing a long integral windbreak panel 6, the segmented windbreak panel 6 is easier to prepare and is more convenient to process, transport and install. At the same time, by installing the windbreak panel 6 in the livestock and poultry house and setting it opposite to the air inlet 12, the windbreak panel 6 can block the airflow entering from the air inlet 12 and change the direction of the airflow, preventing the airflow from blowing directly on the livestock and poultry, thereby avoiding the livestock and poultry from getting cold due to the direct airflow, reducing the risk of livestock and poultry diseases, and promoting the healthy growth of livestock and poultry.

[0101] In related technologies, in order to reduce the number of air inlets 12 and ensure good ventilation, the air inlets 12 are generally designed as long strips, that is, the length of the air inlets 12 is relatively large. Therefore, the baffle plate 6 is also designed as a long strip to match the air inlets 12.

[0102] See Figure 9 In one embodiment, the connector 62 is provided with a connection hole 621, and the connection hole 621 and the end of the windbreak section 61 are inserted into each other to splice the connector 62 and the windbreak section 61 together.

[0103] The wind deflector 6 also includes:

[0104] Fasteners (not shown in the figure) connect the connector 62 and the windbreak section 61 together. This allows the end of the windbreak section 61 to be limited using the connecting hole 621, effectively preventing the end of the windbreak section 61 from wobbling relative to the connector 62. This improves the connection stability between the windbreak section 61 and the connector 62, ultimately enhancing the connection stability between adjacent windbreak sections 61 and resulting in higher structural reliability. Furthermore, the fasteners further reinforce the connection reliability between the connector 62 and the windbreak section 61, further improving structural reliability.

[0105] In one embodiment, the connector 621 extends through both the front and rear ends of the connector 62;

[0106] In two adjacent windbreak sections 61, one end of one is inserted into one end of the connecting hole 621, and the other end of the other is inserted into the other end of the connecting hole 621.

[0107] When the connector 62 connects two adjacent windbreak sections 61, the near ends of the two adjacent windbreak sections 61 abut together. The connecting hole 621, which extends through the connector 62 from both ends, is easier to manufacture and has a simpler processing technology. It also saves material, thus reducing costs. Furthermore, the through-hole 621 allows the near ends of the two adjacent windbreak sections 61 to abut together, increasing the connection reliability and structural reliability of the two adjacent windbreak sections 61.

[0108] In other embodiments, a connection hole 621 is provided at both ends of the connector 62 along its length. The two connection holes 621 at both ends of the connector 62 along its length are separated, and each connection hole 621 is inserted into and engaged with the end of a corresponding windbreak section 61.

[0109] In one embodiment, the connector 62 is provided with a stiffener 622, which extends along the width direction of the connector 62.

[0110] When the connector 62 connects two adjacent windbreak sections 61, the stiffening plate 622 is located between the two adjacent windbreak sections 61. In this way, the stiffening plate 622 increases the structural strength of the connector 62, making the connector 62 less prone to deformation, thereby ensuring that the two adjacent windbreak sections 61 are reliably connected together, resulting in higher structural reliability.

[0111] In one embodiment, the cross-sectional shape of the connector 62 is the same as that of the windproof section 61, so that the connector 62 can also play a good windproof role. There are two stiffeners 622 on the connector 62, and the two stiffeners 622 are placed on both sides of the width direction of the connector 62. Each stiffener 622 is located on the first drainage section 61111 of the corresponding drainage part 6111 on the connector 62.

[0112] Specifically, fasteners can be connection structures such as rivets, screws, and bolts.

[0113] See Figure 5 In one embodiment, the second drive mechanism 5 includes:

[0114] Motor 51, motor 51 is installed on the main body 1 of the livestock and poultry house;

[0115] A traction rope 52, one end of which is mounted on the output shaft of the motor 51;

[0116] At least two supports 53 are provided, the upper end of the supports 53 is hinged to the main body 1 of the livestock and poultry house, at least two supports 53 are arranged at intervals along the length of the wind baffle 6, the supports 53 are provided with a support part, the support part allows the wind baffle 6 to pass through laterally and supports the wind baffle 6, and the other end of the supports 53 is connected to the traction rope 52.

[0117] When the motor 51 rotates in the forward direction, the output shaft rotates and winds the traction rope 52 around it. The bracket 53 is pulled by the traction rope 52 and swings upward relative to the main body 1 of the livestock house. The wind deflector 6 moves towards the air inlet 12 as the bracket 53 swings.

[0118] When motor 51 rotates in the reverse direction, the output shaft rotates and releases the traction rope 52. The bracket 53, under the loosening effect of the traction rope 52, swings downward relative to the main body 1 of the livestock house. The wind deflector 6 moves away from the air inlet 12 as the bracket 53 swings. Thus, starting motor 51 can wind or release the traction rope 52. When the traction rope 52 is wound, it can drive at least two brackets 53 to rotate upward, causing the brackets 53 to flip upward. During the upward rotation of the brackets 53, the wind deflector 6 moves upward in parallel. When the traction rope 52 is released, it can drive at least two brackets 53 to rotate downward, causing the brackets 53 to flip downward. During the downward rotation of the brackets 53, the wind deflector 6 moves downward in parallel, allowing the wind deflector 6 to cover the air inlet 12 or adjust the opening of the second connecting port 13. This second drive mechanism 5 has a simple and practical structure, low maintenance cost, and multiple wind deflectors 6 can be linked by setting one set of second drive mechanisms 5, which simplifies the structure and reduces costs, greatly reducing the overall cost of this ventilation device.

[0119] See Figure 2 In one embodiment, a sealing element 7 is provided on either the main body 1 of the livestock and poultry house or the wind deflector 6. The sealing element 7 is arranged around the air inlet 12. When the wind deflector 6 covers the air inlet 12, the main body 1 of the livestock and poultry house and the wind deflector 6 together compress the sealing element 7 to seal the air inlet 12. Thus, in hot weather, the livestock and poultry house needs to use wet curtains and other air vents to bring in air. In this case, the air inlet 12 needs to be sealed to ensure that the airflow treated by the wet curtain can enter the designated location of the livestock and poultry breeding room 11. In addition, the sealing element 7 can also play a buffering role when the wind deflector 6 covers the air inlet 12, avoiding hard contact between the wind deflector 6 and the main body 1 of the livestock and poultry house and causing damage to the wind deflector 6 and the main body 1 of the livestock and poultry house.

[0120] In one embodiment, the sealing element 7 is provided on the main body 1 of the livestock and poultry house to reduce the weight of the wind deflector 6, thereby reducing the load on the second drive mechanism 5.

[0121] See Figure 1 The livestock and poultry house, which can provide uniform ventilation, also includes a rain shelter structure 8. The rain shelter structure 8 is located above the top of the main body 1 of the livestock and poultry house, and the projection of the rain shelter structure 8 can cover the air inlet 12.

[0122] In one embodiment, the projection of the rain shelter structure 8 can cover the top of the livestock and poultry house body 1, so as to achieve a good sunshade effect.
