Description

Technical Field

[0001] This invention relates to an intelligent water-cooled chicken cage and its usage method, and more particularly to an intelligent water-cooled breeding rooster cage for alleviating summer heat stress and its usage method, belonging to the technical fields of intelligent chicken cages and heat stress relief for breeding roosters. Background Technology

[0002] During the summer, when temperatures rise, chickens are prone to heat stress, manifesting as decreased feed intake, reduced egg production, suppressed immune function, and increased mortality. The root cause of heat stress is that the chicken's thermoregulation capacity is overloaded by the combined effects of high external temperature and relative humidity, leading to elevated body temperature, increased respiratory rate, and impaired blood circulation, especially in the blood-rich feet area where heat easily accumulates. In actual production, caged laying hen houses have high flock densities, and breeding roosters, often located below the hens in their cages, experience more severe heat stress compared to the hens, resulting in reduced semen quality in the roosters and consequently affecting the fertilization rate of hatching eggs.

[0003] In actual production, existing overall cooling measures have limitations. While adding air inlets and outlets or using fans and exhaust fans to increase airflow can lower the temperature inside the coop, the effect of simple ventilation is limited in hot and humid weather, and excessive wind speed can easily cause chickens to catch a chill or experience stress. Using the principle of water evaporation to absorb heat can significantly reduce the temperature of the air entering the coop, but it will significantly increase the relative humidity inside the coop. When the humidity is too high, it will aggravate heat stress, and it will not help the chickens dissipate heat locally. Spraying cold water directly on the roof or walls can lower the overall temperature by about 3-5°C, but water droplets falling on the chickens can easily wet their feathers and make them feel uncomfortable, and the effect on local heat dissipation from the chickens' feet is still not obvious. Reducing the heat load by reflecting or blocking solar radiation is a passive cooling method, and its effectiveness is greatly affected by weather and season, and it cannot respond quickly to temperature fluctuations. The above-mentioned equipment mostly rely on high-power fans, refrigeration units, or high-pressure water pumps, which have high energy consumption and significant long-term operating costs, especially in large-scale farms.

[0004] The feet of chickens are unfeathered and have a network of arterial and venous anastomoses, making them the most vascularized part of the rooster's body. In cold weather, these blood vessels constrict to reduce heat loss, while in hot weather, they dilate to increase heat dissipation. This makes them one of the most efficient heat dissipation areas for chickens, and localized temperature increases directly affect the overall thermal balance. While existing overall cooling methods can lower the ambient temperature inside the coop, they often fail to ensure sufficiently rapid and even heat transfer between the chicken's feet and the ground or standing platform. "Wet foot mats" or "cold water troughs" are often designed to avoid conforming to the natural standing posture of chickens, leading to their reluctance to use them, or their poor effectiveness due to large temperature fluctuations and uneven heat transfer. Therefore, by utilizing the chicken's preference for standing on perches (platforms), a localized, controllable, and low-energy-consumption cooling device for the chicken's feet can be used to compensate for the shortcomings of overall cooling technology and achieve precise heat stress relief for breeding roosters during hot seasons. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to provide an intelligent water-cooled rooster cage that cools the feet of roosters, assists in heat dissipation, and thus alleviates heat stress in summer. This provides a low-cost, convenient, and effective method in the field of heat stress relief research for roosters, while also providing rooster perching behavior to achieve a welfare effect of making the roosters stand comfortably. Another purpose of this invention is to provide a method for using the intelligent water-cooled rooster cage.

[0006] Technical Solution: The present invention provides an intelligent water-cooled breeding rooster cage for alleviating summer heat stress. The intelligent water-cooled breeding rooster cage includes a cage body, a cooling station, a cold water circulation pipeline system, and a temperature control intelligent platform. The cooling station is located inside the cage body and includes an arc-shaped station body and an mounting groove located below the station body. The surface of the station body has several parallel strip-shaped anti-slip grooves. The cold water circulation pipeline system is composed of metal pipes installed in the mounting groove below the station body. The temperature control intelligent platform provides circulating cold water; the outlet of the temperature control intelligent platform is connected to the inlet of the metal pipes, and the inlet of the temperature control intelligent platform is connected to the outlet of the metal pipes.

[0007] Preferably, the main body of the rooster cage is a single cage or a row of cages connected in series. The width of the platform body inside the single cage is 8-10cm, the curvature is 250-260°, and the height is 2-3cm.

[0008] Preferably, the cooling platform is made of aluminum alloy, and the platform surface is provided with several parallel strip-shaped anti-slip grooves to prevent chicken feet from slipping.

[0009] Preferably, the mounting groove in the cooling station is located in the middle of the station body, the cross-section of the mounting groove is semi-circular, and the inner diameter of the mounting groove is the same as the outer diameter of the metal pipe through which the circulating water flows.

[0010] Preferably, the joint between the metal water pipe and the platform is fixed with heat transfer adhesive, which has a thermal conductivity of 1.6 ± 2.4 W / (mk).

[0011] Preferably, the temperature control intelligent platform includes a water inlet pipe, a chiller connected to the water inlet pipe, a water tank connected to the chiller, a water pump connected to the water tank, and a water outlet pipe connected to the water pump, which is connected to a metal pipe in the cooling station.

[0012] Preferably, the temperature control intelligent platform also includes a core control unit, a water temperature sensor installed at the water pump outlet or inside the water tank, and a flow rate sensor installed on the water inlet pipe; the core control unit is connected to the water pump, chiller, water temperature sensor, flow rate sensor and ambient temperature sensor respectively.

[0013] Preferably, the temperature control intelligent platform also includes a water temperature sensor installed on the water outlet pipe.

[0014] In the above technical solution, metal water pipes bonded with high thermal conductivity adhesive are arranged under the platform. These metal water pipes are connected to a closed-loop cold water circulation system via flexible plastic hoses. The circulating water is cooled by a water pump and a chiller before flowing inside the pipes, achieving rapid heat dissipation from the platform surface. The supporting intelligent temperature control platform uses a metal shell and touch panel, and internally includes an integrated circuit motherboard, power strip, water pump, chiller, and water temperature and flow rate sensors. It can monitor and automatically adjust the water temperature and flow rate in real time, with the water temperature set at 20℃. This maintains the platform temperature within the set comfort zone, thereby providing a localized, precise, and low-energy-consumption cooling effect for the breeding roosters, significantly alleviating heat stress caused by high summer temperatures.

[0015] The method of using the intelligent water-cooled breeding rooster cage for alleviating summer heat stress according to the present invention includes the following steps:

[0016] Assemble the main body of the chicken cage and pass the metal pipe through the main body of the chicken cage. The intelligent water-cooled rooster cage can be a single chicken cage or a row of chicken cages connected in series. The same number of cooling stations are equipped according to the number of individual chicken cages. Each cooling station is installed on the metal pipe of the corresponding individual chicken cage. The cooling station is close to the bottom of the chicken cage. The metal pipe is connected to the temperature control intelligent platform through a plastic hose to form a circulating water path.

[0017] Fill the water tank in the temperature control intelligent platform with water; turn on the power and start the temperature control intelligent platform, and set the water flow rate according to the number of individual cages: when the number of individual cages n is 1≤n≤10, the water flow rate is set to 2 L / min; when the number of individual cages n is 11≤n≤50, the water flow rate is set to 5 L / min; when the number of individual cages n is 51≤n, the water flow rate is set to 10 L / min.

[0018] Turn on the water pump switch to fill the water tank and circulation path; the intelligent temperature control platform is equipped with an environmental sensor probe to monitor the ambient temperature in real time, and can intelligently start the water pump based on the ambient temperature, and record and save the data in real time; based on the real-time ambient temperature T of the chicken house reflected by the intelligent temperature control platform... env And the set critical ambient temperature T for the upper limit of heat stress in breeding roosters during summer. stress (The upper critical temperature for heat stress in normal production breeding roosters can be set in the range of 26-28℃, depending on the age and breed of the rooster.) When the ambient temperature T env > T stress At this time, the chiller begins cooling the water in the tank, with the cooling water temperature set at 20℃, and simultaneously the water pump pumps the cooling water into the metal pipes; when the ambient temperature T... env ≤ T stress At this time, the chiller stops cooling water and the water pump stops working;

[0019] After being cooled by the chiller in the temperature-controlled intelligent platform, the water is pumped into the metal pipes to lower the temperature of the cooling station. When the chicken stands on the cooling station, its feet cool down. The temperature of the chicken feet is then transferred to the cooling water through the cooling station and the metal pipes. The water then flows back into the intelligent platform for recooling.

[0020] The specific steps for assembling the main body of the chicken cage are as follows: number the individual rooster cages, insert the metal pipe through the middle of the side of each individual rooster cage; connect the opening of the metal pipe of the first individual rooster cage to the water outlet of the temperature control intelligent platform; connect the opening of the metal pipe of the last individual rooster cage to the plastic hose, and extend the hose through the top of the cage to the temperature control intelligent platform and connect it to the return water interface.

[0021] In the above technical solution, breeding roosters stand on a cooling platform, using conduction to lower the temperature of their feet, making them feel cool and comfortable, thus alleviating heat stress caused by the high temperature in the chicken house. The platform's shape conforms to the shape of chicken feet, ensuring comfort for the chickens when standing. Metal pipes are used as a cold water circulation system, tightly fitted beneath the platform, making the platform more stable when the roosters use it. Heat-transfer adhesive is used at the joints to help the chickens better transfer heat. The circulation system is connected to an intelligent temperature control platform, which monitors the ambient temperature in real time and controls the water pump operation.

[0022] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention organically combines an aluminum alloy cooling platform, a metal water pipe cooling circulation system and an intelligent temperature control platform to achieve localized and precise cooling of the feet of breeding roosters. It has the advantages of simple structure, low cost, high heat transfer efficiency, convenient operation and data traceability, which can effectively alleviate heat stress in breeding roosters in high-temperature environments in summer and improve breeding efficiency.

[0038] Specifically, the metal pipe 301 in the cold water circulation pipeline system is bonded to the installation groove 202 in the cooling station 2 with high thermal conductivity adhesive. The metal pipe 301 is connected to the temperature control intelligent platform 4 through the flexible plastic hose 302 to form a closed-loop cold water circulation system. The circulating water flows in the pipe after being cooled by the water pump and the chiller, realizing rapid heat dissipation on the surface of the station.

[0040] The cooling platform is made of aluminum alloy. A groove is located in the middle of the platform body, and the groove has a semi-circular cross-section. The metal water pipes are fixed to the platform using heat-transfer adhesive with a thermal conductivity of 1.6 ± 2.4 W / (mK).

[0041] Example 2

[0042] like Figure 4 As shown, this embodiment provides a temperature control intelligent platform, including an inlet pipe 401, a chiller 402, a water tank 403, a water pump 404, an outlet pipe 405, a core control unit 406, a water temperature sensor 407, a flow rate sensor 408, a housing 409, a back panel 410, a circuit board 411, an operation panel 412, an ambient temperature sensor 413, and wheels 414. The inlet pipe 401 is connected to the chiller 402, the chiller 402 is connected to the water tank 403, the water tank 403 is connected to the water pump 404, and the water pump 404 is connected to the outlet pipe 405.

The core control unit 406 is connected to the water pump 404, the chiller 402, the water temperature sensor 407, and the flow rate sensor 408.

[0043] Specifically, the platform's outer shell is made of corrosion-resistant metal, with a touch-screen control panel 412 mounted on the front. Standardized inlet and outlet water interfaces are pre-installed on the outside of the platform for quick connection or disconnection of hoses. The internal structure consists of an inlet pipe 401 and an outlet pipe 405, composed of pressure-resistant flexible plastic hoses, responsible for transporting chilled water from the external circulation system to the internal chiller 402 and then back. The main circuit board is the core control unit 406, integrating a microprocessor, power drive module, communication module (optional Wi-Fi / Bluetooth), and safety protection circuitry. All electrical components are powered, monitored, and commanded through this main board. The circuit strip 411 provides multiple protections including voltage stabilization, overcurrent protection, and overtemperature protection, and is connected to the main board to ensure electrical safety during long-term operation. The water pump 404 is preferably a variable frequency centrifugal pump with a maximum operating efficiency of 10 L / min. Installed on the water pipeline, its speed can be adjusted according to the main board's commands to achieve precise flow rate control. Water tank 403 stores circulating water and provides buffer volume. It is equipped with an overflow port and an air vent to ensure stable system operation during startup and shutdown. Chiller 402 has a rated voltage of 220V, a rated frequency of 50Hz, a power of 250W, a cooling capacity of 600W, and a cooling water volume of ≤300L. Water temperature sensor 407 is preferably a waterproof temperature probe, embedded in the outlet of water pump 404 or inside water tank 403, to collect circulating water temperature in real time and feed it back to the main board. Flow rate sensor 408 is installed on the inlet pipe, using vortex shear or electromagnetic principles to measure instantaneous flow rate, providing a basis for flow rate adjustment by the main board. All electrical components within the platform (including water pumps, chillers, sensors, etc.) are connected to the main board and circuit strips, achieving unified power supply and centralized control, ensuring the reliability and safety of system operation.

[0044] During use, the ambient temperature data monitored by the ambient temperature sensor 413 of the temperature control intelligent platform is displayed on the operation panel 412 in real time and can be uploaded in real time via Wi-Fi. Cooling water enters the cold water circulation pipeline system 3 through the outlet pipe 405 and flows through the metal pipe 301 to the cooling station 2. The heated water flows back to the temperature control intelligent platform through the inlet pipe 401. The water temperature at the inlet and outlet of the temperature control intelligent platform is measured by the water temperature sensor 407 and displayed on the operation panel 412. The heated water is cooled again by the chiller 402. The water volume outside the pipeline is stored in the water tank 403 and pumped into the pipeline by the water pump 404.

[0045] Example 3

[0046] according to Figure 6The diagram shown is a schematic diagram and flowchart of the operation of a rooster cooling station and temperature control intelligent platform according to the present invention, including the following steps:

[0047] S1: The intelligent water-cooled rooster cage can be a single cage or a row of cages connected in series. The same number of cooling stations are provided according to the number of individual cages. Each cooling station is installed on the metal pipe of the corresponding individual cage. The cooling station is close to the bottom of the cage. The metal pipe is connected to the temperature control intelligent platform through a plastic hose to form a circulating water path.

[0048] S2: The cooling station is placed on the metal pipe. It is in cages, with one cooling station in each cage. The cooling station is attached to the metal pipe and the joint is fixed with heat transfer adhesive to enhance the heat transfer effect.

[0049] S3: Fill the water tank in the temperature control intelligent platform with water; turn on the power to start the temperature control intelligent platform, and set the water flow rate according to the number of individual cages: when the number of individual cages n is 1≤n≤10, the water flow rate is set to 2 L / min; when the number of individual cages n is 11≤n≤50, the water flow rate is set to 5 L / min; when the number of individual cages n is 51≤n, the water flow rate is set to 10 L / min; turn on the water pump to fill the circulating water circuit in the water tank; connect the temperature control intelligent platform to the network to monitor the water temperature and water flow rate in real time.

[0050] S4: The ambient temperature sensor probe inside the S3 temperature control intelligent platform can monitor the ambient temperature in real time and record and upload the data in real time;

[0051] S5: Based on the real-time temperature T of the chicken coop reflected by the S4 intelligent temperature control platform. env And the set critical ambient temperature T for the upper limit of heat stress in breeding roosters during summer. stress (The upper critical temperature for heat stress in normal production breeding roosters can be set in the range of 26-28℃, depending on the age and breed of the rooster.) When the ambient temperature T env > T stress At this time, the chiller begins cooling the water in the tank, with the cooling water temperature set at 20℃, and simultaneously the water pump pumps the cooling water into the metal pipes; when the ambient temperature T... env ≤ T stress At this time, the chiller stops cooling water and the water pump stops working.

[0052] S6: Water cooled by the chiller in the temperature control intelligent platform is pumped into the metal pipe to cool the cooling station. When the chicken stands on the cooling station, its feet cool down. The temperature of the chicken feet is then transferred to the cooling water through the cooling station and the metal pipe. The water then flows back into the intelligent platform for recooling.

[0053] Example 4

[0054] This embodiment uses the intelligent water-cooled rooster cage from Examples 1-2 and follows the workflow of Example 3.

[0055] During the high temperatures of summer, 30 healthy adult breeding roosters located near each other in the same chicken coop were randomly divided into three groups: the NP group had no cooling station, the AP group had a cooling station without water circulation, and the CP group had a cooling station with circulating cooling water. The breeding roosters were housed individually in cages, with 10 replicates per group and one breeding rooster per replicate. The inlet water temperature of the cooling system was set to 20℃. The experiment lasted 11 days, with uniform feeding and management throughout. The dimensions of the cooling station are as follows: height 2.5cm; length 30.0cm; width 8.0cm; radius of the built-in locking arc (installation groove 202): 2.0cm. The outer diameter of the metal pipe: 2.0cm, fitted into the installation groove 202.

[0056] The ambient temperature of the cages where the chickens were located and the surface temperature of the cooling platform in the cages of CP and AP group roosters were measured and recorded in real time and continuously, with a data collection interval of 1 hour.

[0057] The surface temperature of rooster feet was measured using an infrared thermometer. Each individual was measured three times, and the average value was taken as the daily data for the surface temperature of rooster feet. The diurnal fluctuation pattern was then analyzed.

[0058] The average surface temperature of chicken feet for each chicken over 11 days during the statistical experiment was calculated. Data processing was performed using SPSS 26.0 software. One-way ANOVA was used to compare the differences in surface temperature of chicken feet among the three groups over 11 days. Duncan's method was used for multiple comparisons. P < 0.01 indicated that the difference between groups was extremely significant and was marked as **.

[0059] The temperature change curve of the cage where the chickens were located during the experiment is shown in the figure below. Figure 7 As shown, the environmental temperature change curves of the NP group (control group), AP group (cooling station without water flow) and CP group (cooling station with water flow) are similar, indicating that the environmental temperatures of the experimental animals are similar.

[0060] The temperature change curve of the cooling platform surface during the test is shown in the figure. Figure 8 As shown. The surface temperature of the cooling station of AP group fluctuates synchronously with the ambient temperature, and its trend is similar to that of the ambient temperature curve ( Figure 7The surface temperatures of the CP group roosters were generally consistent, varying within the range of 25-30℃. However, the surface temperature of the cooling station in the CP group remained around 20℃ throughout the experiment, significantly lower than that of the cooling station in the AP group rooster cages. These results indicate that the cooling design employed in this experiment can efficiently and continuously transfer heat from the cooling station in the rooster cages, thus successfully creating a locally cooled microenvironment for the CP group roosters. This result verifies the effectiveness of the cooling treatment in this experiment and provides direct physical evidence for the subsequent observations of differences in rooster behavior and physiological responses.

[0061] Figure 9 These are the surface temperature change curves of the three groups of chicken feet during the experiment. Figure 10 This is a comparison of the average surface temperature of chicken feet over 11 days during the experiment. Figure 9 The results showed that the surface temperature of the feet of roosters in the CP group remained at the lowest level throughout the experiment, and its fluctuation was the most gradual. Figure 10 One-way ANOVA results showed that the surface temperature of chicken feet in group CP was significantly lower than that in groups NP and AP (P < 0.01), indicating that cooling water can effectively reduce the surface temperature of chicken feet and efficiently promote heat dissipation in roosters. Figure 9 The results showed that the NP group roosters had the highest foot surface temperature, while the AP group roosters had a foot surface temperature between the NP and CP groups. Figure 10 One-way ANOVA results showed that the surface temperature of chicken feet in group AP was significantly lower than that in group CP (P < 0.01), indicating that the water-cooled platform also promoted heat dissipation from the feet of breeding roosters. In conclusion, the water-cooled platform can effectively promote heat dissipation from the feet of breeding roosters during the high-temperature period in summer.

[0062] This embodiment sets up a control group (NP group), a non-water-circulated group (AP group), and a water-circulated group (CP group), and monitors the changes in ambient temperature in the chicken house, temperature of the cooling station, and surface temperature of the chicken feet over 11 days. The results show that the ambient temperature of the three groups of chickens was similar due to their proximity in the same chicken house; the surface temperature of the chicken feet showed a significant difference between the NP group > AP group > CP group (P<0.01), indicating that the intelligent water-cooled rooster cage of this invention can create an efficient local cooling microenvironment and reduce the heat stress load of roosters through conduction heat dissipation.

Turn on the water pump switch to fill the water tank and circulation path; the intelligent temperature control platform is equipped with an environmental sensor probe to monitor the ambient temperature in real time, and can intelligently start the water pump based on the ambient temperature, and record and save the data in real time; based on the real-time ambient temperature T of the chicken house reflected by the intelligent temperature control platform... env And the set critical ambient temperature T for the upper limit of heat stress in breeding roosters during summer. stress When the ambient temperature T env > T stress At this time, the chiller begins cooling the water in the tank, with the cooling water temperature set at 20℃, and simultaneously the water pump pumps the cooling water into the metal pipes; when the ambient temperature T... env ≤ T stress At this time, the chiller stops cooling water and the water pump stops working; After being cooled by the chiller in the temperature-controlled intelligent platform, the water is pumped into the metal pipes to lower the temperature of the cooling station. When the chicken stands on the cooling station, its feet cool down. The temperature of the chicken feet is then transferred to the cooling water through the cooling station and the metal pipes. The water then flows back into the intelligent platform for recooling.

10. The method of using the intelligent water-cooled rooster cage for alleviating summer heat stress according to claim 9, characterized in that, The specific steps for assembling the main body of the chicken cage are as follows: number the individual rooster cages, insert the metal pipe through the middle of the side of each individual rooster cage; connect the opening of the metal pipe of the first individual rooster cage to the water outlet of the temperature control intelligent platform; connect the opening of the metal pipe of the last individual rooster cage to the plastic hose, and extend the hose through the top of the cage to the temperature control intelligent platform and connect it to the return water interface.
