Description

Technical Field

[0001] The present invention relates to the technical field of animal husbandry facilities, and in particular to a sheep house ventilation system and method. Background Art

[0002] Sheep farming has long been a key pillar of my country's livestock industry. With the gradual maturation of sheep farming technology and the continuous upgrading and improvement of facilities and equipment, the foundation has been laid for the large-scale and industrialized development of the industry. The standardization and regularization of sheep house construction, particularly the application of new structures and technologies in sheep house construction, is a key direction for the modernization of the sheep farming industry. Scientifically advanced sheep houses are a crucial prerequisite for large-scale sheep farming.

[0003] Winter in northern China is cold, coinciding with the gestation period for ewes and the first wintering period for growing sheep. Low temperatures cause excessive heat loss, leading to weight loss, miscarriage, and even death. Active heating is prohibitively expensive and difficult to implement. Furthermore, at night, humidity in the shed can reach over 90% to maintain heat, which can easily cause condensation on the sheep's bodies. This accumulates harmful gases indoors, making them susceptible to colds and illnesses during ventilation. Currently, sheep sheds are primarily protected from the elements by windbreaks, which passively slow the temperature drop rather than actively warming them. Furthermore, windbreaks conflict with ventilation, causing harmful gases to accumulate. Excessive inhalation of these gases can lead to poisoning, heart failure, and other systemic illnesses, and even death. Summary of the Invention

[0037] like Figure 1 As shown, an embodiment of the present invention provides a sheep house ventilation system, comprising:

[0038] The sheep house 100 is provided with a solar heat collecting panel;

[0039] An air inlet mechanism is connected to the solar heat collecting panel and communicated with the sheep house 100;

[0040] The exhaust mechanism is connected to the sheep shed 100. As will be understood, the sheep shed 100 is composed of four circumferentially enclosing side walls and a top wall, and is used to house the sheep. The air intake mechanism is connected to the sheep shed 100 to deliver fresh air into the sheep shed 100. The air intake mechanism is connected to the solar thermal panels installed on the sheep shed 100 to heat the air entering the sheep shed 100. The exhaust mechanism is connected to the sheep shed 100 to exhaust exhaust gas from the sheep shed 100, reducing the humidity within the sheep shed 100 and achieving ventilation within the sheep shed 100.

[0041] That is, the air intake mechanism introduces atmospheric air into the sheep house 100. Before the fresh air enters the sheep house 100, it is heated by the solar thermal collector and then enters the sheep house 100, raising the temperature inside the sheep house 100 to be suitable for the growth of the sheep. The exhaust mechanism promptly draws the waste gas inside the sheep house 100 out of the room, while reducing the indoor humidity. The air intake mechanism and the exhaust mechanism work together to introduce fresh air into the sheep house 100, increase the air circulation inside the sheep house 100, ensure that the temperature and humidity inside the sheep house 100 are suitable for the growth of the sheep, and improve the sheep breeding survival rate. It is worth noting that in this embodiment, the air intake mechanism supplies fresh air into the sheep house 100 from the top, and the exhaust mechanism exhausts the waste gas inside the sheep house 100 from the bottom, while increasing the speed of the hot air flowing downward from the top.

[0042] According to one embodiment of the present invention, the air intake mechanism includes an underground ventilation shaft 210, a suction fan 220, and an air inlet pipe 230. The underground ventilation shaft 210 is located outside the sheep house 100, and the suction fan 220 is located inside the underground ventilation shaft 210. The suction end of the suction fan 220 is connected to the outside atmosphere, the air outlet end of the suction fan 220 is connected to the first end of the air inlet pipe 230, and the second end of the air inlet pipe 230 is connected to the sheep house 100. It can be understood that the air intake mechanism includes the underground ventilation shaft 210 located outside the sheep house 100. The underground ventilation shaft 210 is located below ground level and has an open top end to achieve communication with the atmosphere. The suction fan 220 is located inside the underground ventilation shaft 210, preferably at the bottom of the underground ventilation shaft 210, to achieve a slow flow of outside air within the underground ventilation shaft 210.

[0043] Furthermore, the suction end of the suction fan 220 is connected to the outside atmosphere, actively sucking air from the underground ventilation shaft 210. The air outlet end of the suction fan 220 is connected to the first end of the air inlet pipe 230, that is, the lower end of the air inlet pipe 230. The second end of the air inlet pipe 230 is connected to the sheep house 100, that is, the upper end of the air inlet pipe 230 is connected to the top of the sheep house 100. The air inlet pipe 230 is vertically arranged along the height direction of the sheep house 100, so that air is transported from the top of the sheep house 100 to the inside of the sheep house 100. Specifically, the suction fan 220 is connected to the atmosphere through the underground ventilation shaft 210. Under the active suction action of the suction end of the suction fan 220, the outside air enters the air inlet pipe 230 from the air outlet end of the suction fan 220, and the air flows upward from the lower end of the air inlet pipe 230 and is transported to the sheep house 100 from the upper end of the air inlet pipe 230, thereby realizing the air intake of the sheep house 100.

[0044] According to one embodiment of the present invention, an air buffer chamber 240 is provided in the underground ventilation shaft 210, and the suction fan 220 is provided in the air buffer chamber 240. It is understandable that the air buffer chamber 240 is provided at the bottom of the underground ventilation shaft 210, so that the outside air flows into the underground ventilation shaft 210 and is filled and cached in the air buffer chamber 240. In cold areas in winter, the underground temperature is higher than the surface temperature, so the air buffer chamber 240 will have the effect of preheating the air. The suction fan 220 is installed in the air buffer chamber 240 to improve the active suction effect of the suction fan 220, and there is always enough air in the air buffer chamber 240 for the suction fan 220 to be sucked.

[0045] According to one embodiment of the present invention, a glass wall 260 is provided on the exterior of the south-facing wall 110 of the sheep house 100. An insulation layer 250 is provided between the glass wall 260 and the south-facing wall 110. An air inlet duct 230 is located between the glass wall 260 and the insulation layer 250. It is understood that the south-facing wall 110 of the sheep house 100 (i.e., the south-facing wall of the sheep house 100) is provided with the glass wall 260 on its exterior to allow sunlight to penetrate. The insulation layer 250 is provided between the glass wall 260 and the south-facing wall 110 to prevent the heat of the sheep house 100 from escaping outward, thereby improving the insulation of the sheep house 100. The air inlet duct 230 is located between the glass wall 260 and the insulation layer 250, allowing sunlight to penetrate the glass wall 260 and illuminate the air inlet duct, thereby heating the air within the duct and raising its temperature. Simultaneously, the insulation layer 250 provides insulation for the air inlet duct 230, mitigating heat dissipation. The glass wall 260 and the insulation layer 250 provide a stable clamping mechanism for the air intake pipe, ensuring stable gas delivery. It is worth noting that the bottom side of the glass wall 260 is stably mounted on the foundation of the sheep house 100, while the top side of the glass wall 260 is connected to the top wall of the sheep house 100 to ensure stable installation.

[0046] According to one embodiment of the present invention, a solar thermal collector panel 400 is disposed on the south-facing top wall 120 of the sheep shed 100. An air inlet passage 410 is provided between the solar thermal collector panel 400 and the south-facing top wall 120. The second end of the air inlet pipe 230 is connected to the air inlet passage 410. An air inlet 130 is provided on the south-facing top wall 120 for connecting the air inlet passage 410 with the sheep shed 100. It will be appreciated that the solar thermal collector panel 400 disposed on the south-facing top wall 120 at the top of the sheep shed 100 improves the heat collection efficiency of the solar thermal collector panel 400. An air inlet channel 410 is provided between the solar thermal collecting panel 400 and the south-facing top wall 120. The solar thermal collecting panel 400 is sealed and fixed to the south-facing top wall 120 on the circumference of the side opposite to the south-facing top wall 120, and a gap is left between the solar thermal collecting panel 400 and the south-facing top wall 120 to form a sealed air inlet channel 410. The second end of the air inlet pipe 230 is connected to the air inlet channel 410 to realize the delivery of external air into the air inlet channel 410.

[0047] Furthermore, an air inlet 130 is provided on the south-facing top wall 120, connecting the air inlet duct 410 with the sheep house 100. That is, the air in the air inlet pipe 230 enters the air inlet duct 410, where the solar thermal collector 400 collects heat under the sunlight and heats the air in the air inlet duct 410, extending the heating time and converting the air into hot air. This ensures that the temperature of the air entering the sheep house 100 is no lower than the temperature inside the sheep house 100, and the air enters the sheep house 100 through the air inlet 130, thereby raising the temperature inside the sheep house 100.

[0048] According to one embodiment of the present invention, a sealing film 420 and a film-winding motor 430 are provided on the south-facing top wall 120. The first end of the sealing film 420 is vertically lower than the vertical height of the air inlet 130. The second end of the sealing film 420 is connected to the output end of the film-winding motor 430, and the second end of the sealing film 420 is vertically higher than the vertical height of the air inlet 130. It will be appreciated that the sealing film 420 and the film-winding motor 430 are provided on the south-facing top wall 120 to facilitate the control of the opening and closing of the air inlet 130. The first end, or free end, of the sealing film 420 is vertically lower than the vertical height of the air inlet 130, which is the height of the sheep shed 100. The second end, or connecting end, of the sealing film 420 is connected to the output end of the film-winding motor 430, and the second end of the sealing film 420 is vertically higher than the vertical height of the air inlet 130.

[0049] That is to say, when the temperature in the sheep house 100 is suitable for the growth of the sheep and the air intake mechanism is not needed to deliver hot air, the output end of the film rolling motor 430 is reversed to unfold the sealing film 420 rolled on the output end of the film rolling motor 430, and the first end of the sealing film 420 moves downward along the inclined direction toward the south top wall 120 to block the air inlet 130, and the air in the air inlet channel 410 cannot enter the sheep house 100; when the temperature in the sheep house 100 is lower than the temperature required for the growth of the sheep and the air intake mechanism is needed to deliver hot air, the output end of the film rolling motor 430 rotates forward to retract the unfolded sealing film 420 onto the output end of the film rolling motor 430, thereby opening the air inlet 130, and the air inlet channel 410 is connected to the sheep house 100. The air intake mechanism delivers air to the air inlet channel 410, which is then heated by the solar collector panel 400 and enters the sheep house 100, thereby increasing the temperature in the sheep house 100 and ensuring the normal growth of the sheep.

[0050] According to one embodiment of the present invention, the exhaust mechanism includes a slatted floor 310 and an exhaust fan 320. The slatted floor 310 is laid in the sheep house 100. A plurality of manure collecting troughs 330 are provided on the bottom side of the slatted floor 310. The plurality of manure collecting troughs 330 are connected in series through pipes.

[0051] The air inlet of the exhaust fan 320 is connected to the manure collection trough 330, and the air outlet of the exhaust fan 320 is connected to the outside atmosphere. It is understood that the exhaust mechanism includes a slatted floor 310, which is laid in the sheep house 100 and on which the sheep can move. Multiple manure collection troughs 330 are provided on the underside of the slatted floor 310, allowing feces and urine to enter the manure collection troughs 330 through the slats, keeping the slatted floor 310 relatively clean and tidy. At the same time, it is convenient to clean the manure, and the manure collection troughs 330 are regularly removed from the sheep house 100 for disposal. The multiple manure collection troughs 330 are connected in series through pipes to achieve air communication between the manure collection troughs 330 and the sheep house 100.

[0052] Furthermore, the exhaust fan 320 is arranged in the manure collecting trough 330 near the side wall of the sheep house 100, so that the air inlet end of the exhaust fan 320 is connected with the manure collecting trough 330, that is, connected with the sheep house 100, and the air outlet end of the exhaust fan 320 is connected with the outside atmosphere, thereby accelerating the downward diffusion of hot air entering the sheep house 100 from the top of the sheep house 100, and at the same time quickly eliminating harmful gases produced by fermentation of feces in the sheep bed area on the slatted floor 310 and the manure collecting trough 330 at the bottom, thereby realizing air circulation in the sheep house 100.

[0053] According to one embodiment of the present invention, the exhaust volume of the exhaust fan 320 is set to 1.2 times the air intake volume of the suction fan 220 (it can also be set according to the actual size of the sheep house 100) to ensure that the sheep house 100 is a negative pressure environment.

[0054] According to one embodiment of the present invention, a deodorizer is provided at the outlet of the exhaust fan 320. It is understood that in order to prevent odors within the sheep house 100 from being directly discharged outside the sheep house 100 and polluting the air, a deodorizer is provided at the outlet of the exhaust fan 320 to protect the environment.

[0055] According to one embodiment of the present invention, a temperature sensor, a humidity sensor, an ammonia sensor, a hydrogen sulfide sensor, and a carbon dioxide sensor are installed within the sheep house 100. It is understood that multiple temperature sensors, humidity sensors, ammonia sensors, hydrogen sulfide sensors, and carbon dioxide sensors are dispersed throughout the sheep house 100 to respectively monitor the temperature, humidity, ammonia content, hydrogen sulfide content, and carbon dioxide content within the sheep house 100 in real time, ensuring accurate monitoring. To facilitate real-time temperature monitoring outside the sheep house 100, a temperature sensor can be installed on the exterior sidewall of the sheep house 100, or within the air buffer chamber 240.

[0056] According to one embodiment of the present invention, the system further includes a controller electrically connected to the air intake mechanism, the air exhaust mechanism, the temperature sensor, the humidity sensor, the ammonia sensor, the hydrogen sulfide sensor, and the carbon dioxide sensor. It will be appreciated that the controller receives the corresponding parameters monitored by the temperature sensor, the humidity sensor, the ammonia sensor, the hydrogen sulfide sensor, and the carbon dioxide sensor in real time, and thereby controls the operating states of the suction fan 220 and the exhaust fan 320.

[0057] The sheep house ventilation method according to the embodiment of the present invention comprises the following steps:

[0058] The outside air introduced by the air inlet mechanism is heated by the solar thermal collector and then passed into the sheep house to increase the temperature inside the sheep house;

[0059] The exhaust gas in the sheep house is discharged out of the sheep house through the exhaust mechanism to achieve ventilation of the sheep house.

[0060] The ventilation method of the sheep house ventilation system according to the embodiment of the present invention comprises the following steps:

[0061] Analyze and determine the suitable environmental temperature for different sheep breeds and different growth and development periods and the lowest environmental temperature that sheep can withstand -20℃, and store the suitable temperature for ewes and lambs at 3℃~6℃, the delivery room at 12℃~16℃, the minimum temperature at 0℃ and the maximum temperature at 30℃ in the controller's database;

[0062] The controller selects the optimal and minimum temperatures of the sheep house from the controller database according to the manually input growth period of the sheep;

[0063] During the daytime in winter, when the temperature in the sheep house is lower than the minimum temperature, the film roll motor controls the upper vent to open and the suction fan to start. When the temperature reaches the appropriate temperature, it stops. During the nights in winter and in summer, the film roll motor controls the air inlet to close and the suction fan to turn off.

[0064] The exhaust fan is started according to the monitoring parameters of humidity, NH3, H2S and CO2 in the sheep house, as shown in the following table:

[0065] Detection parameters humidity(%) <![CDATA[NH3(mg / m 3 )]]> <![CDATA[H2S(mg / m 3 )]]> <![CDATA[CO2(mg / m 3 )]]> Start conditions ≥75 ≥20 ≥8 ≥1500

[0066] When any of the conditions in the table is met, the exhaust fan starts and lasts for a certain time (more than 10 minutes). The duration can be set manually.

[0067] When the temperature in the sheep house is lower than the lowest temperature in the database for more than 10 minutes, the controller will issue a low temperature alarm;

[0068] If the temperature detected by the temperature sensor in the air buffer chamber is higher than the maximum temperature, the film winding motor controls the air inlet to close and the suction fan to turn off.

[0069] The above one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0070] By setting an air intake mechanism and an exhaust mechanism respectively connected to the sheep house, the air intake mechanism is connected to the solar thermal collecting panel, so that the solar thermal collecting panel heats the air introduced into the sheep house by the air intake mechanism, so as to increase the temperature in the sheep house to a temperature suitable for the growth of sheep. The exhaust mechanism can discharge the air in the sheep house to achieve the ventilation effect of the sheep house, and promptly remove harmful gases in the sheep house, thereby ensuring that the temperature in the sheep house is suitable, the air is fresh and dry, and the survival rate of sheep breeding is improved.
