Description

Technical Field

[0001] This invention relates to the field of beef cattle farming, and more particularly to a type of beef cattle shed for southern regions that can be cooled in summer. Background Technology

[0002] Currently, in the beef cattle farming sector, environmental control in cattle sheds is crucial for the growth and development of beef cattle. Especially in southern regions, the hot and humid summer climate causes significant stress to beef cattle. Traditional cattle sheds typically use fixed roof structures with poor ventilation and heat dissipation, easily leading to excessively high temperatures inside the sheds, affecting the appetite and growth rate of beef cattle, and even causing heatstroke.

[0003] While some existing improvement solutions have added ventilation equipment, they lack effective regulation of sunlight, failing to effectively reflect sunlight to lower the temperature inside the shed in summer, and also making it difficult to utilize sunlight for heat absorption and insulation in winter. Furthermore, the existing adjustable roof structure suffers from poor sealing between adjacent roof panels during opening and closing, leading to leaks. The adjustment mechanism is also cumbersome to operate, making it difficult to achieve automatic linkage between roof panel rotation and sealing, thus reducing ease of use and reliability. Therefore, this solution proposes a method for cooling cattle sheds in southern regions during summer. Summary of the Invention

[0004] The present invention proposes a cooling cattle shed for southern cattle in summer, which solves the problems of poor environmental regulation, poor sealing and cumbersome operation of existing cattle sheds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cooling shed for beef cattle in southern regions during summer includes shed walls, with an adjustable roof installed on top of the walls. The roof includes:

[0007] The mounting frame includes two parallel hollow horizontal plates and a connecting plate fixedly connected between the two horizontal plates. The two horizontal plates and the two connecting plates together form a rectangular frame structure.

[0008] The top plate is provided in multiples, and multiple top plates are arranged side by side along the length of the connecting plate inside the mounting frame to cover the top of the wall. Both ends of the top plate are rotatably connected to two horizontal plates through fixing cylinders. The top plate has a hollow structure, the front of the top plate is black, and the back of the top plate is white.

[0009] A sealing mechanism includes an upper sealing plate located on the upper part of one long side of the top plate, a lower sealing plate located on the lower part of the other long side of the top plate, and an adjustment assembly installed inside the top plate for driving the upper sealing plate and the lower sealing plate to extend and retract. The lower sealing plate has a water groove on its top surface that extends along its length.

[0010] A lifting mechanism, which is installed on the outer wall of the building and is used to drive the lifting of the mounting frame;

[0011] A drive mechanism, which is installed inside the cross plate and is used to drive the adjustment assembly during the lifting and lowering of the mounting frame;

[0012] The transmission mechanism is installed inside the cross plate and linked with the drive mechanism to drive the top plate to flip after the upper and lower sealing plates retract.

[0013] The above solution, by setting up roof panels with different colors on the front and back, allows the roof panels to be flipped according to seasonal needs to absorb or reflect sunlight. In conjunction with the linkage of the lifting mechanism, drive mechanism and transmission mechanism, it realizes the automatic retraction of the sealing plate and the flipping of the roof panels during the lifting and lowering of the shed, solving the problems of the existing cattle shed environment adjustment being monotonous and the operation being cumbersome.

[0014] As a further improvement to the above solution, the front of the building wall is provided with an entrance and exit, and windows are installed on both sides of the building wall.

[0015] As a further improvement to the above solution, the adjustment assembly includes a bidirectional screw rotatably connected inside the top plate along its length, a moving block with two opposite threaded regions on the outer periphery of the bidirectional screw, and two fixed plates movably disposed inside the top plate. One long side of the upper sealing plate and one long side of the lower sealing plate extend to the inner side of the top plate and are respectively fixed to the two fixed plates. Two connecting rods are hinged on each of the two moving blocks, and the two connecting rods on the same moving block are respectively hinged to the outer walls of the two fixed plates.

[0016] The above solution uses a bidirectional screw to drive the moving block to move, and a connecting rod to drive the extension and retraction of the fixed plate and sealing plate, resulting in a stable structure.

[0017] As a further improvement to the above solution, the bidirectional screw is coaxially arranged with the fixed cylinder, and one end of the bidirectional screw extends through the fixed cylinder to the inner side of the horizontal plate and is fixed with a transmission gear. The transmission gear is coaxially arranged with the bidirectional screw. The driving mechanism includes a transmission rack that is movably arranged inside the horizontal plate along its length direction, an adjusting screw that is rotatably connected to the inner wall of one side of the horizontal plate, a fixed gear that is coaxially fixed to the outer periphery of the adjusting screw, and a fixed rack that is movably arranged inside the horizontal plate. A screw hole is opened at one end of the transmission rack near the adjusting screw, and one end of the adjusting screw extends into the screw hole and is threadedly connected to it. The bottom surface of the transmission rack slides against the bottom inner wall of the horizontal plate. The bottom of the fixed rack extends to the bottom of the horizontal plate and is fixed to the outer wall of the building wall through a mounting plate.

[0018] The above solution utilizes the cooperation between the fixed rack and the fixed gear when the mounting frame is raised and lowered to drive the adjusting screw to rotate, which in turn drives the transmission rack to move, thus realizing the conversion of the lifting motion into the driving force for the operation of the adjusting component.

[0019] As a further improvement to the above solution, the other end of the transmission rack is provided with a connecting hole along its length direction, and a connecting rod along its length direction is fixed on the inner wall of the side of the horizontal plate opposite to the connecting hole. One end of the connecting rod is movably inserted into the connecting hole and fits into its interior.

[0020] The above solution ensures the linearity and stability of the transmission rack movement through the cooperation between the connecting rod and the connecting hole.

[0021] As a further improvement to the above solution, the lifting mechanism includes multiple telescopic rods installed on the front and back of the building wall, with the movable end of the telescopic rods fixedly connected to the bottom surface of the horizontal plate.

[0022] The above solution achieves stable lifting and lowering of the installation frame through the extension and retraction of the telescopic rod, providing the necessary space for the top plate to be flipped.

[0023] As a further improvement to the above solution, the transmission mechanism includes a toothed plate movably disposed within the horizontal plate and an elastic element installed at the end of the toothed plate away from the connecting rod. The bottom surface of the toothed plate slides against the bottom inner wall of the horizontal plate, and multiple ratchet teeth are installed on the top surface of the toothed plate. One end of the fixed cylinder extends into the horizontal plate and is fitted with a ratchet that engages with the ratchet teeth. A push plate is fixed at the end of the transmission rack away from the connecting rod. The push plate engages with the toothed plate, and there is a gap between the push plate and the toothed plate at the section away from the elastic element so that the transmission rack moves a certain distance before engaging with the toothed plate.

[0024] The above scheme ensures the timing logic of the sealing plate shrinking first and then the top plate flipping by setting the interval between the push plate and the toothed plate, while the cooperation between the ratchet and the ratchet teeth ensures the accuracy of the top plate flipping angle.

[0025] As a further improvement to the above solution, a buffer hole is provided at the end of the toothed plate away from the push plate, which is arranged along the length of the toothed plate. The elastic element includes a spring provided in the buffer hole and a buffer rod fixed to one end of the spring. The other end of the spring is fixed to the inner wall of the buffer hole, and the other end of the buffer rod extends to the outside of the buffer hole and is fixed to the inner wall of the horizontal plate.

[0026] Through the above technical solution, the elastic element can automatically restore the toothed plate to its original position during the descent of the mounting frame.

[0027] As a further improvement to the above solution, a through hole coaxially arranged with the fixed cylinder is provided on the horizontal plate. A limiting component to increase the rotation resistance of the fixed cylinder is installed between the outer periphery of the fixed cylinder and the through hole. Two oppositely arranged locking holes are provided on the inner wall of the through hole. The limiting component includes two elastic columns that are respectively installed on the outer periphery of the fixed cylinder by elastic elements. One end of the elastic column is a hemispherical structure and is locked in the locking hole.

[0028] The above solution increases the resistance to the rotation of the fixed cylinder by using a limiting component, preventing the top plate from flipping arbitrarily in a non-driven state and improving the stability of the structure.

[0029] As a further improvement to the above solution, L-shaped exhaust pipes are rotatably installed on both outer walls of the building. The short end of the exhaust pipe is rotatably connected to the building wall and extends to the inner side of the building wall. A linkage gear is also sleeved on the outside of the short end of the exhaust pipe. A linkage rack is fixed on the bottom surface of both connecting plates, and the two linkage racks mesh with the linkage gears on the two exhaust pipes respectively.

[0030] By utilizing the chimney effect, the above technical solutions can accelerate the removal of heat from cattle sheds during the summer.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] 1. This invention uses a top plate with black and white sides. In winter, the black side can face upward to absorb heat and increase the temperature inside the shed; in summer, the white side can face upward to reflect sunlight and reduce the temperature inside the shed. At the same time, the lifting mechanism raises the shed roof and flips the top plate to a vertical position, forming an air circulation channel to accelerate heat dissipation, effectively solving the problem of difficult cooling in beef cattle sheds in southern regions during summer.

[0033] 2. Through the setting of the sealing mechanism, when the top plate is laid flat, the upper sealing plate and the lower sealing plate of the adjacent top plate overlap each other. Together with the water groove on the lower sealing plate, the gap between the adjacent top plates is effectively sealed to prevent rainwater from seeping in and to ensure the airtightness of the cattle shed.

[0034] 3. Through the coordinated operation of the lifting mechanism, drive mechanism and transmission mechanism, the sealing plate is automatically retracted and the top plate is flipped during the rising of the installation frame, and it is automatically reset during the falling process. The operation is simple, the degree of automation is high, and the intensity of manual labor is reduced.

[0035] 4. By setting the interval between the push plate and the toothed plate in the transmission mechanism, the sequence of sealing action and flipping action is ensured, avoiding mechanism interference and ensuring the reliability of equipment operation.

[0036] 5. By coordinating the exhaust pipe with the linkage mechanism, the angle of the exhaust pipe is automatically adjusted while the roof is being raised and lowered. Utilizing the chimney effect, this enhances the ventilation capacity of the cattle shed and further improves the breeding environment. Attached Figure Description

[0049] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0050] Example 1:

[0051] like Figure 1 , Figure 2 and Figure 5As shown, this embodiment provides a cooling shed for beef cattle in southern regions during summer, including a shed wall 1 and an adjustable roof installed on top of the shed wall 1. The roof includes a mounting frame, a top plate 4, a sealing mechanism, a lifting mechanism, a drive mechanism, and a transmission mechanism. The mounting frame serves as the supporting skeleton of the roof, comprising two parallel hollow horizontal plates 2 and a connecting plate 3 fixedly connected between the two horizontal plates 2. The two horizontal plates 2 and the two connecting plates 3 together form a rectangular frame structure, which covers the top opening of the shed wall 1.

[0052] The horizontal plate 2 and the connecting plate 3 can be welded or bolted together using metal profiles to ensure sufficient structural strength to support the top plate 4. The horizontal plate 2 is a hollow structure, while the connecting plate 3 serves to connect the two horizontal plates 2 and enhance the overall rigidity of the mounting frame.

[0053] Multiple top plates 4 are provided, arranged side by side along the length of the connecting plate 3 inside the mounting frame to cover the top of the wall 1. Both ends of each top plate 4 are rotatably connected to two horizontal plates 2 via fixing cylinders 19, allowing the top plate 4 to rotate around the axis of the horizontal plates 2. Furthermore, the front of the top plate 4 is black, and the back of the top plate 4 is white.

[0054] The roof panel 4 features different colors on its front and back to adapt to the temperature control needs of different seasons. In winter, the black front of the roof panel 4 faces upwards. The black surface effectively absorbs heat from solar radiation and transfers it into the cattle shed, thus providing insulation and raising the temperature inside the shed, which is beneficial for the growth of beef cattle. In summer, the white back of the roof panel 4 faces upwards. The white surface has a high reflectivity, reflecting most of the solar radiation away and reducing heat transfer into the shed, thereby lowering the temperature inside the shed and alleviating heat stress in the beef cattle. This method of temperature control based on the physical properties of color requires no additional energy consumption, making it energy-saving and environmentally friendly.

[0055] A lifting mechanism is installed on the outer wall of the housing wall 1 and is used to drive the installation frame to rise and fall. In this embodiment, the lifting mechanism includes multiple telescopic rods 7 installed on the front and back of the housing wall 1, and the movable end of the telescopic rod 7 is fixedly connected to the bottom surface of the horizontal plate 2.

[0056] In this embodiment, the telescopic rod 7 can be in the form of an electric push rod, hydraulic cylinder, or pneumatic cylinder. By controlling the extension and retraction of the telescopic rod 7, the entire mounting frame can be moved up and down relative to the wall 1. When the mounting frame rises, a gap is formed between the top plate 4 and the top of the wall 1, providing necessary space for the top plate 4 to flip, avoiding interference between the top plate 4 and the wall 1 during the flipping process; at the same time, this gap can also form a ventilation channel to promote air circulation. When the mounting frame descends, the top plate 4 tightly covers the top of the wall 1, providing shelter from wind and rain. The number of telescopic rods 7 can be reasonably configured according to the length and weight of the mounting frame, for example, in... Figure 1In the embodiment shown, two telescopic rods 7 are symmetrically arranged on the front and back of the wall 1 to ensure the stability of the installation frame during the lifting process.

[0057] In addition, the front of the barn wall 1 has an entrance and exit 6 to facilitate the entry and exit of beef cattle and feeders; windows are installed on both sides of the barn wall 1 to enhance natural ventilation and lighting inside the barn.

[0058] Through the above structure, the lifting mounting frame and the top plate 4 with different colors on the front and back are used to achieve the initial adjustment of the lighting and ventilation environment inside the cowshed, providing the installation foundation and operation prerequisite for the linkage operation of the sealing mechanism, drive mechanism and transmission mechanism in the subsequent embodiments.

[0059] Example 2:

[0060] This embodiment is an improvement on embodiment 1 in that:

[0061] The sealing mechanism includes an upper sealing plate 15 located on the upper part of one long side of the top plate 4, a lower sealing plate 20 located on the lower part of the other long side of the top plate 4, and an adjustment assembly installed inside the top plate 4 for driving the upper sealing plate 15 and the lower sealing plate 20 to extend and retract. A water groove is provided on the top surface of the lower sealing plate 20 along its length.

[0062] Combination Figure 6 , Figure 7 and Figure 8 As shown, the adjustment assembly includes a bidirectional screw 16 rotatably connected inside the top plate 4 along its length, a movable block 13 threadedly sleeved on the outer periphery of the bidirectional screw 16 in two opposite threaded regions, and two fixed plates 21 movably disposed within the top plate 4. One long side of the upper sealing plate 15 and one long side of the lower sealing plate 20 extend to the inner side of the top plate 4 and are respectively fixed to the two fixed plates 21. Two connecting rods 14 are hinged to each of the two movable blocks 13, and the two connecting rods 14 on the same movable block 13 are respectively hinged to the outer walls of the two fixed plates 21.

[0063] The surface of the bidirectional screw 16 is provided with two sections of threads with opposite directions of rotation. When the bidirectional screw 16 rotates, the two moving blocks 13 will move closer or further apart along the screw axis under the drive of the threads. Specifically, when the moving blocks 13 move closer together, the connecting rod 14 pushes the two fixed plates 21 to move in opposite directions, thereby causing the upper sealing plate 15 and the lower sealing plate 20 to extend out of the top plate 4 simultaneously; conversely, when the moving blocks 13 move further apart, the connecting rod 14 pulls the fixed plates 21 back to their original positions, causing the sealing plates to retract. In addition, the top plate 4 has a receiving hole 29 inside for accommodating the upper sealing plate 15 and the lower sealing plate 20. When the sealing plates retract, their main body can be completely embedded in the receiving hole 29, thereby avoiding mechanical interference between adjacent sealing plates during the flipping process of the top plate 4 and ensuring the smoothness of the flipping action.

[0064] Furthermore, the bidirectional screw 16 is coaxially arranged with the fixed cylinder 19, and one end of the bidirectional screw 16 extends through the fixed cylinder 19 to the inner side of the horizontal plate 2 and is fixed with a transmission gear 17. The transmission gear 17 is coaxially arranged with the bidirectional screw 16. The drive mechanism includes a transmission rack 11 that is movably disposed inside the horizontal plate 2 along its length, an adjusting screw 23 that is rotatably connected to the inner wall of one side of the horizontal plate 2, a fixed gear 22 that is coaxially fixed to the outer periphery of the adjusting screw 23, and a fixed rack 9 that is movably disposed inside the horizontal plate 2. A screw hole is opened at one end of the transmission rack 11 near the adjusting screw 23, and one end of the adjusting screw 23 extends into the screw hole and is threadedly connected to it. The bottom surface of the transmission rack 11 slides against the bottom inner wall of the horizontal plate 2, and the bottom of the fixed rack 9 extends to the bottom of the horizontal plate 2 and is fixed to the outer wall of the wall 1 through a mounting plate.

[0065] When the lifting mechanism drives the mounting frame to rise, the fixed rack 9 moves downward relative to the horizontal plate 2. Since the fixed rack 9 meshes with the fixed gear 22, the fixed gear 22 drives the adjusting screw 23 to rotate. The adjusting screw 23 is threadedly engaged with the transmission rack 11, converting the rotational motion of the adjusting screw 23 into linear motion of the transmission rack 11 along the length of the horizontal plate 2. The moving transmission rack 11 eventually meshes with the transmission gear 17, driving the transmission gear 17 to rotate, which in turn drives the bidirectional screw 16 to rotate, achieving automatic retraction of the sealing plate. No additional power source is required; the mechanical energy of the roof lifting mechanism is utilized, reducing equipment costs and failure rates.

[0066] To ensure the linearity and stability of the transmission rack 11's movement, a connecting hole 25 is provided at the other end of the transmission rack 11, extending along its length. A connecting rod 26, extending along its length, is fixed to the inner wall of the side of the cross plate 2 opposite to the connecting hole 25. One end of the connecting rod 26 is movably inserted into the connecting hole 25 and fits into its interior. The cooperation between the connecting rod 26 and the connecting hole 25 serves a guiding function, preventing the transmission rack 11 from deflecting or wobbling during movement, ensuring that the threaded transmission between the adjusting screw 23 and the transmission rack 11 always maintains a good meshing state, and improving the reliability of the transmission mechanism.

[0067] Example 3:

[0068] This embodiment is further improved on the basis of Embodiments 1 and 2 in that:

[0069] Combination Figure 9As shown, the transmission mechanism includes a toothed plate 12 movably disposed within the horizontal plate 2 and an elastic element installed at the end of the toothed plate 12 away from the connecting rod 26. The bottom surface of the toothed plate 12 slides against the bottom inner wall of the horizontal plate 2. Multiple ratchet teeth are installed on the top surface of the toothed plate 12. One end of the fixed cylinder 19 extends into the horizontal plate 2 and is fitted with a ratchet 18 that engages with the ratchet teeth. A push plate 24 is fixed at the end of the transmission rack 11 away from the connecting rod 26. The push plate 24 engages with the toothed plate 12, and the push plate 24 and the section of the toothed plate 12 away from the elastic element are spaced apart so that the transmission rack 11 moves a certain distance before engaging with the toothed plate 12.

[0070] In the initial stage of the mounting frame's ascent, the transmission rack 11 moves along with the horizontal plate 2. At this time, the push plate 24 has not yet contacted the toothed plate 12, the toothed plate 12 remains stationary, and the ratchet 18 does not mesh with the ratchet teeth. During this stage, the movement of the transmission rack 11 only drives the adjusting screw 23 to rotate, which in turn drives the bidirectional screw 16 to rotate, causing the upper sealing plate 15 and the lower sealing plate 20 to retract into the top plate 4. As the mounting frame continues to rise, the push plate 24 crosses this "gap" and contacts the toothed plate 12, beginning to push the toothed plate 12 to move. The ratchet teeth on the toothed plate 12 mesh with the ratchet 18 on the fixed cylinder 19, thereby driving the fixed cylinder 19 to rotate and causing the top plate 4 to flip. This timing logic design effectively avoids mechanical interference or damage to the sealing plate caused by flipping before the sealing plate is fully retracted, ensuring the reliability and smoothness of equipment operation.

[0071] Furthermore, a buffer hole 27 is provided at the end of the toothed plate 12 away from the push plate 24, extending along the length of the toothed plate 12. The elastic element includes a spring disposed in the buffer hole 27 and a buffer rod 28 fixed to one end of the spring. The other end of the spring is fixed to the inner wall of the buffer hole 27, and the other end of the buffer rod 28 extends to the outside of the buffer hole 27 and is fixed to the inner wall of the cross plate 2. When the toothed plate 12 is pushed by the push plate 24, the buffer rod 28 slides in the buffer hole 27 and compresses the spring. When the mounting frame descends, the spring recovers its deformation, thereby driving the toothed plate 12 to move back automatically and return to its original position. The ratchet 18 and ratchet teeth are designed so that the toothed plate 12 will not drive the ratchet to rotate during the backward movement.

[0072] In addition, combined Figure 10As shown, a through hole coaxially arranged with the fixed cylinder 19 is provided on the horizontal plate 2. A limiting component to increase the rotational resistance of the fixed cylinder 19 is installed between the outer periphery of the fixed cylinder 19 and the through hole. Two opposing locking holes 30 are provided on the inner wall of the through hole. The limiting component includes two elastic posts 31 respectively installed on the outer periphery of the fixed cylinder 19 by elastic elements. One end of the elastic post 31 is a hemispherical structure and is locked in the locking hole 30. A receiving hole 29 for installing the elastic post 31 is provided on the outer periphery of the fixed cylinder 19. The elastic element is a spring or elastic rubber. One end of the elastic post 31 extends into the receiving hole 29 and is connected to the elastic element. The other end of the elastic element is fixed to the inner wall of the receiving hole 29. Under the elastic force of the elastic element, the elastic post 31 always has the tendency to move outward, so that its hemispherical end is tightly locked in the locking hole 30 on the inner wall of the through hole. When the top plate 4 is in a flat position or flipped to a specific angle, the engagement of the elastic post 31 and the locking hole 30 significantly increases the resistance to the rotation of the fixed cylinder 19, preventing the top plate 4 from accidentally flipping or shaking due to wind or its own weight, thus ensuring the positional stability of the top plate 4 in a non-driven state. The fixed cylinder 19 will only rotate when the driving force provided by the transmission mechanism is sufficient to overcome the engagement resistance between the elastic post 31 and the locking hole 30, which also prevents the toothed plate 12 from driving the ratchet 18 to rotate during its reversal.

[0073] Example 4:

[0074] This embodiment is further improved upon embodiments 1-3 in that:

[0075] Combination Figure 1 , Figure 3 and Figure 4 As shown, L-shaped exhaust pipes 5 are rotatably installed on both outer walls of the housing wall 1. The short end of the exhaust pipe 5 is rotatably connected to the housing wall 1, and the short end of the exhaust pipe 5 extends to the inner side of the housing wall 1. A linkage gear 8 is also sleeved on the outside of the short end of the exhaust pipe 5. A linkage rack 10 is fixed on the bottom surface of both connecting plates 3. The two linkage racks 10 mesh with the linkage gears 8 on the two exhaust pipes 5 respectively.

[0076] In this embodiment, the lifting motion of the shed roof is converted into the swinging motion of the exhaust pipe 5 through the cooperation of the linkage rack 10 and the linkage gear 8. Specifically, when the lifting mechanism drives the mounting frame to rise, the linkage rack 10 fixed to the bottom surface of the connecting plate 3 moves upward accordingly. Since the linkage rack 10 meshes with the linkage gear 8 on the exhaust pipe 5, the upward-moving linkage rack 10 drives the linkage gear 8 to rotate, which in turn drives the exhaust pipe 5 to rotate, causing its long end to open upward. This utilizes the chimney effect to facilitate the use of external airflow to accelerate the discharge of hot air from the shed. Conversely, when the mounting frame descends, the exhaust pipe 5 rotates in the opposite direction to reset, with its opening facing downward, which is beneficial for heat preservation. This linkage design requires no manual adjustment and achieves adaptive adjustment of the ventilation opening angle according to the state of the shed roof, further optimizing the ventilation efficiency of the cattle shed.

[0077] To more clearly illustrate the technical effects of the present invention, the following description is provided in conjunction with specific application scenarios:

[0078] Scenario 1: Summer high temperature cooling mode.

[0079] During the high temperatures of summer in southern China, ventilation needs to be enhanced and sunlight reflected to lower the temperature inside the cattle shed. At this time, the lifting mechanism is activated, and the telescopic rod 7 extends to drive the mounting frame upwards. In the initial stage of ascent, the fixed rack 9 moves downwards relative to the horizontal plate 2, driving the fixed gear 22 to rotate. This, in turn, drives the transmission rack 11 to move via the adjusting screw 23. The transmission rack 11 first drives the adjusting assembly, causing the bidirectional screw 16 to rotate, which in turn causes the upper sealing plate 15 and lower sealing plate 20 to retract into the receiving hole 29 inside the top plate 4, releasing the sealing overlap between adjacent top plates 4. As the mounting frame continues to rise, the push plate 24 at the end of the transmission rack 11 contacts the toothed plate 12, pushing the toothed plate 12 to move. Through the meshing of the ratchet 18 and the ratchet teeth, the fixed cylinder 19 rotates, causing the top plate 4 to flip to a vertical position. At this point, an airflow channel is formed between adjacent top plates 4, and the white back facing upwards reflects most of the solar radiation, effectively reducing heat absorption. At the same time, the rising mounting frame drives the linkage rack 10 upward, causing the exhaust pipe 5 to rotate to an upward-facing position, accelerating the discharge of hot air from the barn. During summer rains, the mounting frame 5 can be raised further until the top plate is flipped up to the white back facing upward, then the telescopic rod 7 is activated to retract until the mounting frame is lowered back to the top of the barn wall. During this descent, the top plate 4 does not rotate, thus effectively preventing rainwater from entering the cattle barn.

[0080] Scenario 2: Winter insulation mode.

[0081] During the cold winter months, to maintain the temperature inside the cattle shed, it is necessary to reduce heat loss and utilize sunlight for heating. At this time, the telescopic rod 7 retracts, driving the mounting frame to descend. During descent, the fixed rack 9 drives the fixed gear 22 to rotate in the opposite direction, the transmission rack 11 moves in the opposite direction, the push plate 24 separates from the toothed plate 12, the toothed plate 12 resets under the action of the elastic element, and the ratchet mechanism allows the fixed cylinder 19 to rotate under gravity or the action of an auxiliary mechanism until the top plate 4 is laid flat with the black front facing upwards. At this time, the black front absorbs solar radiation heat, transferring it into the shed and increasing the temperature inside. Simultaneously, the reverse movement of the transmission rack 11 drives the adjusting assembly, causing the upper sealing plate 15 and the lower sealing plate 20 to extend. The upper sealing plate 15 of the adjacent top plate 4 overlaps with the lower sealing plate 20, forming a multiple seal with the water trough on the lower sealing plate 20, effectively preventing cold air backflow and rain / snow infiltration. In addition, the descent of the mounting frame causes the linkage rack 10 to move downward, driving the exhaust pipe 5 to rotate to a small angle or bend downward, reducing the convection of cold air and further enhancing the heat preservation performance of the cattle shed.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
