Although they can resist the cold to a certain extent, poor ventilation can easily lead to the occurrence of diseases. Although open sheep houses can ensure good ventilation conditions, they cannot effectively keep warm in the severe winter season, which seriously affects the health and production performance of the sheep.

[0003] Several common winter cold prevention measures on the market include using plastic film to cover the ceiling, laying straw mats or wood chips as the ground insulation layer, and installing heating equipment such as electric blankets and heaters.

[0016] Compared with the prior art, the present invention provides a ventilation device, a temperature-controlled sheep house based on the device, and a temperature control method, which have the following beneficial effects: 1. In the ventilation and air exchange device, during the process of air discharge or air intake, the circulating filter belt circulates in the ventilation chamber and the cleaning chamber under the drive of the circulation drive unit and the tension of several filter support rollers, and the circulating filter belt has multiple layers along the direction of air flow, so that when the air passes through each layer of the circulating filter belt, it can be continuously filtered and moisture absorbed by each layer of the circulating filter belt, and the circulating filter belt circulates in the ventilation chamber and the cleaning chamber. When the circulating filter belt passes through the cleaning mechanism, it can be cleaned to restore the filtering capacity of the circulating filter belt, and when the circulating filter belt passes through the dehumidification mechanism, it can be dried to restore the dehumidification capacity of the circulating filter belt, so that the circulating filter belt can restore the filtering and dehumidification capacity when it re-enters the ventilation chamber, so that during ventilation and air exchange, impurities inside the house can be isolated to avoid clogging the circulating filter belt and the ventilation drive mechanism, while dehumidifying the inside of the house, water vapor outside the house can be prevented from entering to block the moisture exchange between the inside and the outside, so that the inside of the house can be kept dry and the ventilation effect inside the house can be guaranteed.

[0017] 2. This ventilation device can be driven by the friction force of each friction wheel to circulate along the route passing through each circulation drive roller and each filter support roller when the circulation filter belt passes through each friction wheel, and can be expanded by the expansion roller when the circulation filter belt passes through each filter support roller, so as to avoid the support roller shaft exerting pressure on the internal hygroscopic layer and squeezing out the moisture absorbed therein. Similarly, when the circulation filter belt passes through each circulation drive roller, it can be expanded by the corresponding friction wheel, so as to avoid the circulation drive roller exerting pressure on the internal hygroscopic layer and squeezing out the moisture absorbed therein, and can ensure that the expansion state of the internal hygroscopic layer during the movement inside the ventilation chamber can maintain the hygroscopic effect of the internal hygroscopic layer to the greatest extent.

[0018] 3. In this ventilation and air exchange device, each side cleaning roller is respectively arranged on both sides of the circulating filter belt, so that each side cleaning roller can frictionally clean the two sides of the circulating filter belt respectively, and remove the impurities adsorbed on the two sides of the circulating filter belt due to ventilation. Moreover, since the tangential direction of rotation of each side cleaning roller is opposite to the moving direction of the circulating filter belt on the side, the interaction between each side cleaning roller and the circulating filter belt is stronger, and the impurities adsorbed on the two sides of the circulating filter belt can be removed more effectively, thereby effectively restoring the filtering capacity of the circulating filter belt.

[0019] 4. In this ventilation device, the circulating filter belt is located between two side pressing rollers. Therefore, under the auxiliary effect of gravity and the pressing of the two side pressing rollers, the moisture in the internal hygroscopic layer is squeezed out and can move downward along the two side pressing rollers and fall into the collecting funnel, thereby avoiding splashing of moisture during the squeezing process and effectively collecting moisture, and effectively removing moisture from the internal hygroscopic layer, so that after the circulating filter belt is separated from the two side pressing rollers, the internal hygroscopic layer can expand again and restore its hygroscopicity.

[0020] 5. This temperature-controlled sheep house based on ventilation and air exchange devices is equipped with an intelligent temperature control system and ventilation and air exchange devices, which not only ensures a warm and comfortable microclimate environment inside the sheep house, but also takes into account the effect of energy conservation and emission reduction, significantly improves the warmth retention and stability of the sheep house, reduces the incidence of diseases caused by cold, and improves the overall growth rate and reproductive efficiency of the flock. Through the setting of manure storage tanks and collection channels, the manure is sent from the collection channel to the manure storage tank, which effectively prevents the manure from freezing, avoiding the problem of conventional sheep houses in winter environments, where excrement freezes inside the sheep house and cannot be discharged, resulting in the inconvenience of having to wait for the temperature to rise before shoveling it out manually or with a forklift.

[0021] 6. This temperature control method improves the accuracy and response speed of temperature and humidity control through automatic temperature control systems and ventilation devices, reduces livestock loss rates caused by environmental changes, enhances the reliability and robustness of the system, and can respond quickly and appropriately even in the face of sudden climate changes, and can fully ensure the stability of the internal environment of the sheep house in winter, effectively ensuring the winter survival rate of sheep cubs.

When the air moves from the internal vent 23 to the external vent 24, it passes through the circulating filter belt 31 in sequence to continuously filter the air; a cleaning mechanism 5 and a dehumidification mechanism 6 are arranged inside the cleaning chamber 22. When the circulating filter belt 31 passes through the cleaning mechanism 5, it can be cleaned to restore the filtering capacity of the circulating filter belt 31, and when the circulating filter belt 31 passes through the dehumidification mechanism 6, it can be dried to restore the dehumidification capacity of the circulating filter belt 31.

[0027] In specific use, the ventilation device is first installed on the roof of a house that needs ventilation through the fixed frame 1, and the internal vents 23 and the external vents 24 are respectively placed inside and outside the house; then, the ventilation drive mechanism 4 is used to control the air flow direction inside the ventilation chamber 21, and the air can be selectively driven from the internal vents 23 to the external vents 24 (to discharge the dirty air in the room), and the air can also be selectively driven from the external vents 24 to the internal vents 23 (to inhale the clean air outside), and in actual use, multiple ventilation devices of this kind can be installed on the roof, and multiple ventilation devices of this kind can perform air discharge and air inhalation operations respectively at the same time; In the above-mentioned process of air discharge or air intake, the circulating filter belt 31 circulates inside the ventilation chamber 21 and the cleaning chamber 22 under the drive of the circulating drive unit 33 and the tension of the plurality of filter support rollers 32, and the circulating filter belt 31 has multiple layers along the direction of air flow, so that when the air passes through each layer of the circulating filter belt 31, it can be continuously filtered and moisture-absorbed by each layer of the circulating filter belt 31, and the circulating filter belt 31 circulates inside the ventilation chamber 21 and the cleaning chamber 22, and when the circulating filter belt 31 passes through the cleaning mechanism 5, it can The filtering capacity of the circulating filter belt 31 can be restored by cleaning, and the dehumidification capacity of the circulating filter belt 31 can be restored by drying when the circulating filter belt 31 passes through the dehumidification mechanism 6, so that the filtering and dehumidification capacity of the circulating filter belt 31 can be restored when the circulating filter belt 31 re-enters the ventilation chamber 21, so that during ventilation, impurities inside the house can be isolated to avoid clogging the circulating filter belt 31 and the ventilation drive mechanism 4, and while dehumidifying the inside of the house, water vapor outside the house can be prevented from entering and blocking the moisture exchange between the inside and the outside, so that the inside of the house can be kept dry and the ventilation effect inside the house can be guaranteed.

[0028] Example 2: Please refer to Figure 2-Figure 9 , which is different from the above-mentioned embodiment, each filter support roller 32 is arranged on both sides of the interior of the installation shell 2, each filter support roller 32 includes a support roller shaft 321, both ends of the support roller shaft 321 are respectively embedded in the interior of the installation shell 2, and both ends of each support roller shaft 321 are provided with a stretching roller 322; the circulating filter belt 31 can pass through the stretching rollers 322 corresponding to each filter support roller 32 in sequence, and the circulating filter belt 31 can first pass through the filter support roller 32 on the side closest to the internal ventilation port 23 inside the installation shell 2, pass through each filter support roller 32 in sequence, and finally pass through the filter support roller 32 on the side closest to the external ventilation port 24.

[0029] The circulation drive unit 33 includes a plurality of circulation drive rollers 331 and a circulation drive motor 332. Both ends of the circulation drive rollers 331 are provided with friction wheels 333. The circulation drive motor 332 is respectively connected to each circulation drive roller 331 for power transmission (see FIG. Figure 6-Figure 7The movable end of the circulating drive motor 332 is coaxially fixed with a driving pulley, and a driven pulley is arranged at the top of each circulating drive roller 331. The driving pulley and each driven pulley are connected and transmitted by independently arranged belts, wherein the belt is a toothed belt with teeth grooves inside, and the driving pulley and each driven pulley are pulleys with teeth on the outside, so that the driving pulley and the driven pulley can be transmitted by belts). The rotation speed and rotation direction of each circulating drive roller 331 are the same; the circulating filter belt 31 can pass through the friction wheels 333 corresponding to each circulating drive roller 331 in turn, and each friction wheel 333 has friction with the circulating filter belt 31. When each friction wheel 333 rotates with the corresponding circulating drive roller 331, it can drive the circulating filter belt 31 to circulate inside the ventilation chamber 21 and the cleaning chamber 22.

[0030] The circulating filter belt 31 includes two external filter layers 311 and an internal hygroscopic layer 312. The internal hygroscopic layer 312 is arranged between the two external filter layers 311. The two sides of the external filter layers 311 are pasted and closed to each other. Both ends of the external filter layer 311 are provided with friction coatings 313. The friction coating 313 fits between the corresponding expansion rollers 322 when passing through each filter support roller 32, and the friction coating 313 fits between the corresponding friction wheels 333 when passing through each circulating drive roller 331. When the circulating filter belt 31 passes through each filter support roller 32 and each circulating drive roller 331, the internal hygroscopic layer 312 is separated from each filter support roller 32 and each circulating drive roller 331, and the internal hygroscopic layer 312 remains in an expanded state.

[0031] When in use, the external filter layer 311 has a certain adsorption effect, can adsorb impurities in the air, and can remove the adhered impurities through friction cleaning, while the internal hygroscopic layer 312 has a certain hygroscopic effect, can adsorb moisture in the air, and can squeeze moisture out of the internal hygroscopic layer 312 through pressing.

[0032] The inner hygroscopic layer 312 is fixed inside the two outer filter layers 311, and the width of the inner hygroscopic layer 312 is smaller than the width of the two outer filter layers 311. The two ends of the outer filter layers 311 along the width direction are adhered to each other, so that the two outer filter layers 311 and the inner hygroscopic layer 312 can move in the direction of the friction force when the friction coating 313 on either side is subjected to friction force, and can be driven by the friction force of each friction wheel 333 when the circulating filter belt 31 passes through each friction wheel 333 and circulate along the route passing through each circulating drive roller 331 and each filter support roller 32. The circulating filter belt 31 can move and be expanded under the action of the expansion roller 322 when passing through each filter support roller 32, so as to avoid the support roller shaft 321 exerting pressure on the internal hygroscopic layer 312 and squeezing out the moisture absorbed therein. Similarly, when the circulating filter belt 31 passes through each circulating drive roller 331, it can be expanded under the action of the corresponding friction wheel 333, so as to avoid the each circulating drive roller 331 exerting pressure on the internal hygroscopic layer 312 and squeezing out the moisture absorbed therein, and the expansion state of the internal hygroscopic layer 312 during the movement inside the ventilation chamber 21 can maintain the hygroscopic effect of the internal hygroscopic layer 312 to the greatest extent.

[0033] Example 3: Please refer to Figure 2-Figure 8 , which is different from the above-mentioned embodiment, is that the cleaning mechanism 5 includes a plurality of side cleaning rollers 51, a collecting unit 52 and a cleaning drive motor 53, and each side cleaning roller 51 is respectively arranged on both sides of the circulating filter belt 31; each side cleaning roller 51 is respectively powered by the cleaning drive motor 53, and the tangential direction of rotation of each side cleaning roller 51 is opposite to the moving direction of the circulating filter belt 31 on the side.

[0034] The collecting unit 52 includes a collecting bucket 521 and a collecting drawer 522. The collecting bucket 521 is arranged below each of the side cleaning rollers 51. The collecting bucket 521 closes on one side of the collecting drawer 522. The collecting drawer 522 can slide out from the side of the cleaning chamber 22 close to the external vent 24. Under the action of the collecting bucket 521 and gravity, the filtered materials swept off from both sides of the circulating filter belt 31 by each side cleaning roller 51 can fall into the collecting bucket 521 and enter the collecting drawer 522 for collection.

[0035] When in use, since each side cleaning roller 51 is respectively arranged on both sides of the circulating filter belt 31, each side cleaning roller 51 can frictionally clean the two sides of the circulating filter belt 31 respectively, and separate the impurities adsorbed on the two sides of the circulating filter belt 31 due to ventilation. Moreover, since the tangential direction of rotation of each side cleaning roller 51 is opposite to the moving direction of the circulating filter belt 31 on the side, the interaction between each side cleaning roller 51 and the circulating filter belt 31 is stronger, and the impurities adsorbed on the two sides of the circulating filter belt 31 can be more effectively removed, thereby effectively restoring the filtering capacity of the circulating filter belt 31. The removed impurities can enter the collecting bucket 521 below under the action of gravity, and move toward the collecting drawer 522 along the inclined direction of the bottom surface of the collecting bucket 521. The impurities collected in the collecting drawer 522 can then be taken out from the side of the cleaning chamber 22 close to the external ventilation port 24, and the impurities collected in the collecting drawer 522 can be removed.

[0036] The dehumidification mechanism 6 includes two side pressing rollers 61 and a collecting funnel 62. The two side pressing rollers 61 are respectively arranged on both sides of the circulating filter belt 31, and the collecting funnel 62 is arranged below the two side pressing rollers 61. A drainage pipe 63 is arranged at the bottom of the collecting funnel 62, and one end of the drainage pipe 63 away from the collecting funnel 62 extends out of the side of the cleaning chamber 22 close to the external vent 24; the circulating filter belt 31 can pass through the gap between the two side pressing rollers 61. Under the pressure of the two side pressing rollers 61, the moisture in the internal hygroscopic layer 312 is squeezed out and slides along the outer sides of the two side pressing rollers 61 to the inside of the collecting funnel 62. After separating from the circulating filter belt 31 and the side pressing rollers 61, the internal hygroscopic layer 312 expands again to restore its hygroscopicity.

[0037] Therefore, when in use, since the circulating filter belt 31 is located between the two side pressing rollers 61, under the auxiliary action of gravity and the pressing of the two side pressing rollers 61, the moisture in the internal hygroscopic layer 312 is squeezed out and can move downward along 1 of the two side pressing rollers 61 and fall into the collecting funnel 62, which can avoid splashing during the water squeezing process while effectively collecting the moisture and effectively remove the moisture in the internal hygroscopic layer 312. Therefore, after the circulating filter belt 31 is separated from the two side pressing rollers 61, the internal hygroscopic layer 312 can expand again and restore its hygroscopicity. In actual use, a dryer can be set inside the cleaning chamber 22 and at the rear end of the side pressing roller 61 located in the moving direction of the circulating filter belt 31, so as to dry the internal hygroscopic layer 312 after most of the moisture is removed after squeezing, completely remove the moisture in the internal hygroscopic layer 312, and avoid mildew of the internal hygroscopic layer 312.

[0038] The ventilation drive mechanism 4 includes a drive mounting frame 41 and a plurality of drive fans 42. The air outlet directions of the drive fans 42 are consistent and can be adjusted synchronously. The drive fans 42 jointly provide the power for the air to pass through the multi-layer circulation filter belt 31 during the movement between the internal vent 23 and the external vent 24. In specific use, the air movement direction of one such ventilation device can be adjusted by the drive fan 42. In actual use, multiple such ventilation devices can be installed on the roof, and multiple such ventilation devices can perform air exhaust and air intake operations respectively at the same time.

[0039] Example 4: Please refer to Figure 1 , a temperature-controlled sheep house based on a ventilation device, using a ventilation device as described in Example 1 to Example 3, characterized in that it also includes: a heat-insulating wall, a roof insulation layer, an automatic temperature control system and a sheep manure cleaning device; The main body of the sheep house is composed of thermal insulation walls and roof insulation layers, which are supported by a main frame made of high-strength steel with good load-bearing capacity and corrosion resistance. The thermal insulation walls are made of double-layer hollow bricks and filled with polystyrene foam boards to enhance the sound insulation and thermal insulation effects. The roof insulation layer uses materials with high reflectivity and low thermal conductivity, such as aluminum foil composite materials. The temperature inside the sheep house is controlled by an automatic temperature control system, which integrates temperature sensors, controllers and heaters to achieve constant temperature control through preset thresholds. The ventilation device is arranged inside the roof insulation layer, and the interior of the sheep house is ventilated through the ventilation device. The ventilation device can remove harmful gases while maintaining suitable indoor humidity; The sheep manure cleaning equipment includes several collecting channels and manure storage tanks. The collecting channels all lead to the manure storage tanks, and the collecting channels clean downward toward one side of the manure storage tank, which can effectively prevent the manure from freezing and avoid the problem that the excrement in the conventional sheep house in the winter environment is frozen inside the sheep house and cannot be discharged, resulting in the inconvenience of having to wait for the temperature to rise and then shovel it out manually or with a forklift.

[0040] This temperature-controlled sheep house based on ventilation and air exchange device adopts steel frame structure as the main body, combined with polystyrene foam board in double-layer hollow brick wall, roof insulation layer made of aluminum foil composite material and other advanced technologies and materials. It is also equipped with intelligent temperature control system and ventilation and air exchange device, which not only ensures the warm and comfortable microclimate environment inside the sheep house, but also takes into account the effect of energy saving and emission reduction, significantly improves the warmth retention and stability of the sheep house, reduces the incidence of diseases caused by cold, and improves the overall growth rate and reproductive efficiency of the flock; realizes automated management and monitoring, reduces labor input, and improves economic benefits; through the application of renewable energy, reduces carbon emissions, which is in line with the development direction of green ecological agriculture.

[0041] Embodiment 5: A temperature control method for controlling the temperature inside a temperature-controlled sheep house based on a ventilation device as described in Embodiment 4; The automatic temperature and humidity control system includes an automatic temperature control system and a ventilation device, specifically including a main control unit, a temperature and humidity sensor, a light sensor, a fan, a heating device, a humidifier, a drainage pump, an irrigation system, and a communication module; The main control unit is responsible for receiving data from various sensors and sending instructions to the actuator after processing; temperature and humidity sensors are installed at different locations inside the greenhouse to monitor temperature and humidity changes in real time; light sensors are used to detect the intensity of external natural light to assist in determining whether the sunshade net needs to be opened; fans, heating devices and humidifiers are used to lower and raise the temperature and increase the air humidity respectively; drainage pumps are used to remove excess water to prevent waterlogging; irrigation systems ensure that plants receive an appropriate amount of water supply; communication modules allow farmers to remotely monitor the greenhouse status through mobile phone APP or other terminal devices.

[0042] When the temperature and humidity sensors detect that the environmental parameters deviate from the set values, the main control unit will initiate corresponding measures to restore them to the ideal range. For example, when the temperature is too high, first try to cool it down with the fan; if the goal is still not achieved, open the sunshade to reduce direct sunlight. On the contrary, when the temperature is too low, the heating device starts to run until it returns to normal. Similarly, humidity control follows similar principles. In addition, you can view historical records, adjust setting parameters, and even simulate emergency response strategies in emergencies at any time through the mobile phone APP.

[0043] This temperature control method improves the accuracy and response speed of temperature and humidity control, reduces livestock losses due to environmental changes, enhances the reliability and robustness of the system, and can respond quickly and appropriately even in the face of sudden climate changes, and can fully ensure the stability of the internal environment of the sheep house in winter, effectively ensuring the winter survival rate of sheep cubs.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
