Description

Technical Field

[0001] The present invention relates to the technical field of poultry breeding houses, and in particular to a novel poultry breeding house based on an intelligent fresh air system and a breeding house ventilation method. Background Art

[0002] In recent years, with the improvement of people's living standards and the growing demand for eggs, my country's poultry farming industry, including chickens and ducks, has experienced rapid development. Layer farming has been particularly rapid, and laying hen farming, where chickens, ducks, and other poultry live, has become a crucial component of today's laying hen industry. Traditional laying hen houses are simple structures. While factory-style chicken farming facilities, which emerged in the late 1950s, not only provide an environment suitable for chicken growth and development, but also meet requirements for mechanization, scientific management, and sanitation and epidemic prevention.

[0003] For example, a Chinese patent (publication number CN210959932U) discloses a new type of laying hen house. Through the cooperation of the fence and the chicken house building, the top of the fence is connected to the U-shaped frame through a barrier net, and the inner wall of the U-shaped frame is also installed with a barrier net, which provides an outdoor activity space for the laying hens and prevents the laying hens from flying out of the chicken house, making it convenient to collect the eggs laid by the laying hens.

[0004] However, there are still many problems in the environmental control of existing breeding houses, and the impact of environmental control on poultry production has not received due attention. The existing breeding house ventilation includes horizontal ventilation and vertical ventilation, but the horizontal ventilation has a large cooling range in a short time and cannot be used in winter when the temperature is low. The vertical ventilation has uneven temperature and is difficult to cool in summer. The existing breeding house ventilation cannot match the temperature season, resulting in poor air quality, fluidity and renewal rate in the breeding house, which not only affects the health and survival rate of chickens and ducks, but also has a great impact on the health of staff. Summary of the Invention

[0005] In order to solve the problem that the existing ventilation of poultry houses in the above-mentioned prior art cannot be compatible with the temperature season, the present invention provides a new poultry house and ventilation method based on an intelligent fresh air system.

DETAILED DESCRIPTION

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] At present, the laying hen farming industry is developing particularly rapidly. In this embodiment, laying hen farming is taken as an example. In today's laying hen farming industry, small and medium-sized farms have become an important part of laying hen farming. Although the gap between my country's laying hen farming and the international advanced level in terms of breed, nutrition, disease control, etc. is gradually narrowing, there is still a big gap in environmental control.

[0037] For example, breeding houses generally have poor ventilation, poor air quality in chicken houses, difficult to control seasonal temperature changes, insulation and ventilation in the winter are inconsistent, and the cooling effect in the summer is poor. In addition, the traditional construction method of breeding houses causes uneven temperature in the chicken houses; the air flow is poor and the renewal rate is low, the disinfection is not thorough enough, and the temperature and humidity are unbalanced, resulting in turbid air in the farm, high content of harmful gases, and high content of bacteria and other microorganisms.

[0038] At the same time, due to the special physique of poultry, they are more sensitive to changes in external temperature and humidity and the turbidity of the gas in the breeding plant. Only by creating better environmental conditions can we ensure the survival rate and health rate of chickens and improve their production performance and economic benefits.

[0039] like Figure 1 As shown, the present invention provides a new poultry breeding house based on an intelligent fresh air system, including a breeding plant 10 with several breeding areas and an external circulation component and a dual circulation component connected to the breeding plant 10, the dual circulation component includes a hollow U-shaped tube 20, one side of the hollow U-shaped tube 20 is a protruding end, and the protruding end is connected to the breeding plant 10; the other side of the hollow U-shaped tube 20 is provided with an opening 21, the position of the opening 21 corresponds to the protruding end, and a rotatable ventilation baffle 22 is provided at the opening 21.

[0040] When implementing it specifically, Figures 1 to 8As shown, several breeding areas are provided in the breeding plant 10, in which laying hens, ducks and other poultry can be raised. The external circulation component and the dual circulation component are both connected to the breeding plant 10. The dual circulation component includes a hollow U-shaped tube 20. One side of the hollow U-shaped tube 20 is a protruding end. One side of the protruding end of the hollow U-shaped tube 20 is connected to the breeding plant 10. An opening 21 begins to be provided on the other side of the hollow U-shaped tube 20. The opening 21 is provided in the straight tube part of the hollow U-shaped tube 20. The position of the opening 21 corresponds to the position of the protruding end. A rotatable ventilation baffle 22 is provided at the opening 21.

[0041] When the temperature is high in summer, the ventilation baffle 22 rotates toward the inside of the hollow U-shaped tube 20, so that the opening 21 is in an open state, and the air inside the breeding plant 10 flows outward, cooperating with the external circulation component to realize air flow exchange in the breeding plant 10, thereby achieving a cooling effect in summer;

[0042] When the temperature is low in winter, the ventilation baffle 22 rotates to fit horizontally with the hollow U-shaped tube 20, closing the opening 21 and sealing the straight tube portion of the hollow U-shaped tube 20, so that the breeding plant 10 can achieve internal air purification internal circulation or mixed suction semi-internal circulation, thereby achieving the purpose of heat preservation and air purification in the breeding plant 10 in winter, thereby making the air environment compatible with the seasonal temperature, improving the health rate and survival rate of chickens and ducks, and ensuring the health of the staff.

[0043] Preferably, in this embodiment, each breeding area is equipped with a temperature and humidity sensor, an ammonia sensor and a wind speed sensor, and a central controller receiving the temperature and humidity sensors, ammonia sensors and wind speed sensors is provided inside the breeding plant; a temperature sensor is provided on the hollow U-shaped tube 20 located outside the breeding plant 10. When the temperature outside the breeding plant 10 is between 16 and 27 degrees Celsius, the central controller determines that it is summer and the temperature is high; when the temperature outside the breeding plant 10 is lower than 16 degrees Celsius, the central controller determines that it is winter and the temperature is low;

[0044] The central controller controls the opening or closing of the external circulation component or the dual circulation component by receiving signals from various sensors, circulates and purifies the air in the breeding plant 10, and cools or keeps it warm, so that the air environment is compatible with the seasonal temperature, improves the health and survival rate of chickens and ducks, and ensures the health of the staff.

[0045] In this embodiment, the model of the wind speed sensor is an RS485 wind speed sensor; the model of the central controller is Arduino UNO R3; the model of the ammonia sensor is an RS485 ammonia temperature and humidity transmitter with a measuring range of 0-50ppm; the temperature and humidity sensor is a common sensor in the prior art and will not be described in detail here.

[0046] like Figure 1 、 Figure 2 、 Figure 3 As shown, the external circulation component includes a plurality of air inlet lofts 30 arranged in an array. The air inlet lofts 30 are located in the center of the gable roof of the breeding plant 10. Each air inlet loft 30 is hollow and connected to the breeding plant 10 through a disinfection chamber 40. Rotating waterproof covers 32 that are engaged with waterproof protrusions 31 are installed on both sides of the air inlet loft 30. The inner side of the rotating waterproof cover 32 is provided with a waterproof groove 34 that is compatible with the waterproof protrusion 31.

[0047] A waterproof protrusion 31 is provided on the outer wall of the air inlet loft 30. The waterproof protrusion 31 is U-shaped. A cooling water curtain 33 is provided between the waterproof protrusions 31. In this embodiment, the two ends of the cooling water curtain 33 are respectively connected to a water supply pipe and a drain pipe. The cooling water curtain 33 is a common water curtain or wet curtain in the prior art and will not be described in detail here. When the temperature is high in summer, the rotating waterproof cover 32 is opened relative to the air inlet loft 30, and the air enters the upper part of the breeding plant 10 through the cooling water curtain 33, and then enters the breeding plant 10 through the disinfection chamber 40 below the air inlet loft 30.

[0048] When encountering severe weather such as heavy rain, the rotating waterproof cover 32 is closed relative to the air inlet attic 30, the waterproof protrusion 1 is embedded in the waterproof groove 34, and the rotating waterproof cover 32 is rotated to fit the air inlet attic 30 to prevent rainwater from entering the interior of the breeding plant 10 through the gaps in heavy rain and strong winds.

[0049] like Figure 1 、 Figure 4 As shown, the disinfection chamber 40 is respectively connected to the air inlet attic 30 and the breeding plant 10. A dense grid 41, a water collecting plate 42 and a rotatable first outlet grid 43 are provided in the disinfection chamber 40 from top to bottom. The air passes through the cooling water curtain 33 and enters the air inlet attic 30 and passes through the dense grid 41. Since the air contains a high amount of moisture, water droplets are formed when passing through the dense grid 41 and attached to the dense grid 41. The water collecting plate 42 can receive the water droplets to prevent them from entering the breeding plant 10. In this embodiment, the water collecting plate 42 is connected to a drainage pipe for easy drainage. The water collecting plate 42 is a common water collecting plate in the prior art and will not be described in detail here.

[0050] like Figure 1 、 Figure 4 As shown, specifically, in this embodiment, the disinfection chamber 40 is diamond-shaped when viewed from the side, and the left and right sides of the disinfection chamber 40 are triangular prism-shaped. A plurality of disinfection ultraviolet lamps 44 are provided on the upper oblique sides of the triangular prisms on the left and right sides of the disinfection chamber 40. The disinfection ultraviolet lamps 44 provided on the upper oblique sides of the triangular prisms on the left and right sides of the disinfection chamber 40 can avoid causing harm to humans or animals and poultry;

[0051] A rotatable second outlet shroud 45 is provided on the lower oblique sides of the triangular prisms on the left and right sides of the disinfection chamber 40; when the temperature is high in summer, the air enters the air inlet attic 30 through the cooling water curtain 33 and passes through the dense grid 41. The disinfection ultraviolet lamp 44 can irradiate and disinfect the air. The disinfected air can enter the breeding plant 10 through the first outlet shroud 43 or the second outlet shroud 45.

[0052] Preferably, the central controller receives signals from the temperature and humidity sensors and wind speed sensors in each breeding area. When it is found that the temperature in a breeding area is higher, the first outlet wind cascade 43 or the second outlet wind cascade 45 can be controlled to rotate toward the breeding area. The rotation of the first outlet wind cascade 43 and the second outlet wind cascade 45 is a common technical means in the prior art and will not be repeated here.

[0053] like Figure 1 、 Figures 5 to 8 As shown, the dual-circulation component further includes a first fan and a second fan provided inside the breeding plant 10. In this embodiment, the first fan is a forward-rotating fan, and the second fan is a forward-reversing fan. The protruding end includes a first protruding end 23 and a second protruding end 24. The first fan is provided at the first protruding end 23, and the second fan is provided at the second protruding end 24.

[0054] When the temperature is high in summer, the rotating waterproof cover 32 is opened relative to the air inlet loft 30, and the air enters the upper part of the breeding plant 10 through the cooling water curtain 33, and then enters the breeding plant 10 through the disinfection room 40 below the air inlet loft 30;

[0055] The central controller controls the ventilation baffle 22 to rotate toward the inside of the hollow U-shaped tube 20 to open the opening 21. The first fan and the second fan rotate forward. The air passing through the cooling water curtain 33 and the air inlet attic 30 enters the breeding plant 10 from different angles through the disinfection chamber 40. Under the action of the first fan and the second fan, a negative pressure is formed inside the breeding plant 10. The air in the breeding plant 10 flows toward the first fan and the second fan, enters the hollow U-shaped tube 20 through the first fan and the second fan, and is discharged to the external environment from the opening 21.

[0056] like Figures 5 to 8 As shown, an air separation plate 25 is provided within the first protruding end 23. The air separation plate 25 is L-shaped. A rotatable air inlet sash 26 is provided on one side of the air separation plate 25, and an exhaust sash 27 is provided on the other side of the air separation plate 25. Several disinfecting ultraviolet lamps 44 are provided in the hollow U-shaped tube 20 between the first protruding end 23 and its corresponding opening 21, between the second protruding end 24 and its corresponding opening 21, and between the two openings 21.

[0057] Preferably, in order to extend the service life of the disinfection ultraviolet lamp 44, when the ammonia concentration in the air in the breeding plant 10 is lower than the safety threshold, the disinfection ultraviolet lamp 44 in the hollow U-shaped tube 20 between the first protruding end 23 and its corresponding opening 21, between the second protruding end 24 and its corresponding opening 21, and between the two openings 21 is used alternately.

[0058] An ammonia sensor and several ozone tubes are also provided in the hollow U-shaped tube 20. The ozone tubes are connected to the ozone generator 11. The ozone generator 11 can be located inside the breeding plant 10. When the ammonia sensor detects that the ammonia exceeds the threshold range, the ozone generator 11 inputs ozone into the hollow U-shaped tube 20 through the ozone tube to decompose and remove the ammonia; preferably, in order to avoid the decomposition of ozone by the disinfection ultraviolet lamp 44, the release port of the ozone tube is located in the hollow U-shaped tube 20 between the two openings 21.

[0059] When the air in the breeding plant is circulated in the winter when the temperature is low, the rotatable waterproof cover 32 is rotated to be closed relative to the air inlet loft 30, the waterproof protrusion 31 is embedded in the waterproof groove 34, and the rotatable waterproof cover 32 is rotated to fit the air inlet loft 30;

[0060] The forward rotation of the first fan creates a negative pressure inside the breeding plant 10, and the air in the breeding plant 10 flows toward the first fan and enters the hollow U-shaped tube 20 through the first fan; several disinfecting ultraviolet lamps 44 in the hollow U-shaped tube 20 between the first protruding end 23 and its corresponding opening 21, between the second protruding end 24 and its corresponding opening 21, and between the two openings 21 disinfect the air; the reverse rotation of the second fan allows the disinfected air to re-enter the breeding plant 10 through the second protruding end 24.

[0061] Among them, the air is disinfected for the first time when passing between the first protruding end 23 and its corresponding opening 1. When passing through the hollow U-shaped tube 20 between the two openings 21, the hollow U-shaped tube 20 between the two openings 21 is disinfected again and irradiated to decompose the incompletely reacted ozone into oxygen. Then, the second fan is reversed to allow the disinfected air to re-enter the breeding plant 10 from the second protruding end 24. At this time, the inlet air sash 26 and the exhaust air sash 27 on both sides of the air dividing plate 25 in the first protruding end 24 are sealed and closed.

[0062] In winter when the temperature is low and the air in the breeding plant is mixed and inhaled in semi-internal circulation, the rotating waterproof cover 32 is rotated to be closed relative to the air inlet loft 30, the waterproof protrusion 31 is embedded in the waterproof groove 34, and the rotating waterproof cover 32 is rotated to fit the air inlet loft 30;

[0063] The inlet air shroud 26 and the exhaust air shroud 27 on both sides of the air dividing plate 25 in the first protruding end 23 are rotated to open. The rotation of the inlet air shroud 26 and the exhaust air shroud 27 is a common technical means in the prior art and will not be described in detail here.

[0064] When both the inlet duct 26 and the exhaust duct 27 are rotated and opened, the air entering the first protruding end 23 through the forward rotation of the first fan is divided into two parts, one of which is discharged into the external atmosphere through the exhaust duct 27; while the second fan is rotated in the reverse direction, a negative pressure is formed in the hollow U-shaped tube 20, and fresh air from the outside enters the hollow U-shaped tube 20 through the inlet duct 26, mixes with the other part of the air, and then enters the breeding plant 10 through the second protruding end 24 after being disinfected by a number of disinfecting ultraviolet lamps 44.

[0065] Preferably, if Figure 1 As shown, a plurality of photovoltaic panels 12 are provided on the outside of the gable roof of the breeding plant 10 , and a plurality of polycrystalline silicon solar cells are provided inside the breeding plant 10 , and the polycrystalline silicon solar cells are electrically connected to the photovoltaic panels 12 .

[0066] During specific implementation, light is irradiated on the roof of the breeding plant 10, and the photovoltaic panels 12 transmit photons to the polycrystalline silicon solar cells, which are absorbed by the silicon material; the energy of the photons is transmitted to the silicon atoms, causing the electrons to jump and become free electrons that gather on both sides of the P-N junction to form a potential difference. When the circuit is connected and under the action of voltage, the current is conducted to generate output power, so that the central controller and other circuit components in the breeding plant 10 can operate normally. Using the photovoltaic panels 12 to charge the polycrystalline silicon solar cells and the solar cells to power the circuit components in the breeding plant 10 are common technical means in the existing technology and will not be repeated here.

[0067] The present invention also provides a ventilation method for a breeding house, including external circulation ventilation and internal circulation ventilation. For external circulation ventilation, the ventilation baffle 22 rotates toward the inside of the hollow U-shaped tube 20 to open the opening 21, and the rotating waterproof cover 32 is opened relative to the air inlet loft 30. The air passes through the cooling water curtains 33 on both sides of the air inlet loft 30 and enters the breeding plant 10 from the disinfection chamber 40. Under the action of the first fan and the second fan, the air is discharged from the opening 21 to the outside through the first protruding end 23 and the second protruding end 24;

[0068] Internal circulation ventilation: the ventilation baffle 22 is rotated to fit horizontally with the hollow U-shaped tube 20 to close the opening 21, the rotating waterproof cover 32 is closed relative to the air inlet attic 30, and the first fan is rotated to form a negative pressure in the breeding plant 10. The air enters the hollow U-shaped tube 20 through the first fan, and the second fan is rotated to allow the sterilized air to enter the interior of the breeding plant 10 from the second protruding end 24.

[0069] In specific implementation, the air in the breeding plant is circulated and purified and cooled or kept warm according to the seasonal temperature. When the temperature is high in summer and external circulation ventilation is used, the rotating waterproof cover 32 is opened relative to the air inlet loft 30, and the air enters the upper part of the breeding plant 10 through the cooling water curtain 33, and then enters the breeding plant 10 through the disinfection chamber 40 below the air inlet loft 30;

[0070] The central controller controls the ventilation baffle 22 to rotate toward the inside of the hollow U-shaped tube 20 to open the opening 21. The first and second fans rotate forward. The air passes through the cooling water curtain 33 and the air inlet loft 30 and enters the breeding plant 10 from different angles through the disinfection chamber 40. Under the action of the first and second fans, a negative pressure is formed inside the breeding plant 10. The air in the breeding plant 10 flows toward the first and second fans, enters the hollow U-shaped tube 20 through the first and second fans, and is discharged to the outside environment through the opening 21.

[0071] When the air in the breeding plant is circulated and ventilated in the winter when the temperature is low, the rotatable waterproof cover 32 is rotated to be closed relative to the air inlet loft 30, the waterproof protrusion 31 is embedded in the waterproof groove 34, and the rotatable waterproof cover 32 is rotated to fit the air inlet loft 30;

[0072] The first fan rotates forward to form a negative pressure inside the breeding plant 10, and the air in the breeding plant 10 flows toward the first fan and enters the hollow U-shaped tube 20 through the first fan; the plurality of disinfecting ultraviolet lamps 44 in the hollow U-shaped tube 20 between the first protruding end 23 and its corresponding opening 21, between the second protruding end 24 and its corresponding opening 21, and between the two openings 21 disinfect the air; the second fan rotates reversely to allow the disinfected air to re-enter the breeding plant 10 through the second protruding end 24;

[0073] During the winter when the temperature is low and the air in the breeding plant is mixed and inhaled in a semi-internal circulation ventilation mode, the rotating waterproof cover 32 is rotated to be closed relative to the air inlet loft 30, the waterproof protrusion 31 is embedded in the waterproof groove 34, and the rotating waterproof cover 32 is rotated to fit the air inlet loft 30. The air inlet sash 26 and the air outlet sash 27 on both sides of the air dividing plate 25 in the first protruding end 23 are rotated to open;

[0074] The air entering the first protruding end 23 through the forward rotation of the first fan is divided into two parts. One part is discharged into the external atmosphere through the exhaust shroud 27. The reverse rotation of the second fan creates a negative pressure in the hollow U-shaped tube 20. Fresh air from the outside enters the hollow U-shaped tube 20 through the inlet shroud 26 and mixes with the other part of the air. After being disinfected by the multiple disinfecting ultraviolet lamps 44, it enters the breeding plant 10 through the second protruding end 24.

[0075] Compared with the existing technology, the present invention provides a new poultry house and ventilation method for a poultry house based on an intelligent fresh air system. By arranging an external circulation component and a dual circulation component in the breeding plant, the air in the breeding plant is circulated, purified, cooled or kept warm, so that the breeding plant can realize external circulation, internal circulation or mixed suction semi-internal circulation for air purification, thereby achieving the purpose of purifying the air in the breeding plant according to the seasonal temperature, making the air environment compatible with the seasonal temperature, improving the health rate and survival rate of chickens and ducks, and ensuring the health of the staff.
