Description

Technical Field

[0001] The present invention relates to the technical field of piglet care, and in particular to a piglet warming device and a piglet living environment control method in western Yunnan. Background Art

[0002] To ensure piglet survival, heating lamps are often installed in farrowing pens to keep piglets warm, preventing them from experiencing excessively low or high temperatures and ensuring their normal development. However, piglets require different temperatures throughout their growth, and conventional heating lamps alone are inconvenient for adjusting their living environment temperature, making it difficult to maintain the optimal temperature range for piglets, which can be detrimental to their growth and development.

[0003] Studies have shown that piglets have limited energy reserves and incomplete hormonal regulation of energy metabolism, making them extremely sensitive to drops in ambient temperature. The optimum temperature is around 35°C within six hours after birth, 32-34°C within two days, and gradually decreases from 30°C to around 25°C after seven days of age. Furthermore, western Yunnan Province is located in the longitudinal valley of the Hengduan Mountains, generally at an altitude of over 3,000 meters. In this high-altitude environment, the temperature difference between day and night is significant. Existing piglet incubators are equipped with only a single heat lamp, and the temperature inside the incubator is uneven, making it difficult to meet the temperature requirements of piglets in western Yunnan. This can easily lead to illness or even death. Therefore, how to rationally control the temperature of piglets' growth environments to improve their survival rates is an urgent engineering challenge currently facing factory-scale pig breeding operations in the western Yunnan border region.

[0004] Crucially, because the incubators used by piglets for living (primarily sleeping) are small and extremely limited in size, once inside, it's impossible to accurately and flexibly monitor their temperature sensitivity, making it difficult, if not impossible, to ensure they remain within the optimal temperature range. Existing methods rely on pig farming technicians adjusting the power of the heat lamps based on experience, but this often results in diarrhea in some piglets. Summary of the Invention

[0005] At least in order to solve the technical problems mentioned in the background technology, the purpose of the present invention is to provide a warming device suitable for piglets in western Yunnan and a method for regulating the living environment of piglets.

[0006] The present invention adopts the following technical solutions.

[0007] A piglet warming device for the western Yunnan region comprises a farrowing pen, wherein an internal array of the farrowing pen is provided with three groups of heating pipes, guardrails are fixedly installed on the front and rear sides of the farrowing pen, an insulation box is placed in the middle of the farrowing pen, a water storage chamber is provided inside the insulation box, and two groups of partitions distributed front and back are fixedly installed in the insulation box inside the water storage chamber, the partitions divide the water storage chamber into three insulation areas at equal intervals, and the insulation boxes are enclosed by the box walls and the heating pipes to form three interconnected insulation spaces, the three insulation spaces corresponding to the three groups of heating pipes one by one, an entrance is opened through the middle of both sides of the insulation box, mounting components are provided on both sides of the insulation box, a plurality of interface pipe sections are fixedly installed on both sides of the insulation box, the interface pipe sections are connected to the water storage chamber, the interface pipe sections are externally connected to heating system 1, the heating pipes are externally connected to heating system 2, and heating system 1 and heating system 2 are respectively connected to a control system; a piglet monitoring terminal and a temperature sensor are provided in each insulation space, and the monitoring terminal and the temperature sensor are respectively connected to the control system.

[0008] In the present invention, the temperatures in the three insulation spaces are controlled at: T1°C, T2°C, and T3°C, respectively. T1°C ≠ T2°C ≠ T3°C. T1, T2, and T3 all refer to the preset initial temperature values, which vary according to the age of the piglets. For example, when the piglets are 1 to 3 days old, the corresponding temperature is 30 to 35°C, and when the piglets are 4 to 7 days old, the corresponding temperature is 28 to 30°C.

[0009] Furthermore, the left-right portion of the heating pipe is laid at the bottom of the insulation space and passes through both sides of the farrowing pen. The front-back portion of the heating pipe is connected between the front-back portions, and the heating pipe serves as a part of the slatted floor.

[0010] Furthermore, three groups of heat dissipation openings are provided on the top of the heat preservation box corresponding to the three heat preservation spaces.

[0011] Furthermore, the thermal insulation box is hinged with a shielding door inside the entrance.

[0012] Furthermore, the installation assembly includes an L-shaped plate fixedly installed on both sides of the insulation box, a threaded hole is provided on the vertical part of the L-shaped plate, a threaded rod is threadedly connected to the L-shaped plate through the threaded hole, a turntable is fixedly installed on the threaded rod near one end of the insulation box, a limit cover is provided on the outer side of the turntable, a fixing plate is fixedly installed on the surface of the limit cover, a guide rod is fixedly installed on the side of the fixing plate away from the insulation box, the guide rod passes through and is slidably connected to the vertical part of the L-shaped plate, a plurality of embedding grooves are provided on the side of the fixing plate near the insulation box, and the fixing plate is fitted on the surface of the vertical column of the guardrail through the embedding grooves.

[0013] A method for regulating the living environment of piglets using the aforementioned warming device comprises the following steps:

[0014] Step 1: Control heating system 1 and heating system 2 to start, and control the temperature in the three insulation spaces to T1℃, T2℃, and T3℃ respectively.

[0015] Step 2: Obtain the position and posture of the piglet in the thermal insulation space;

[0016] Step 3: Adjust the temperature of each insulation space in the incubator according to the position and posture of the piglets.

[0017] Furthermore, the postures include a posture in which the piglets lie prone and huddled together, a posture in which the piglets lie prone and spaced apart from each other, and a posture in which the piglets stand;

[0018] The processing module of the control system performs the following steps when executing the program:

[0019] S1: Obtain the position and posture of the piglet in the thermal insulation space, as well as the temperature of each thermal insulation space;

[0020] S2:

[0021] When the piglets are in a prone and huddled position in the same insulation space A, the temperature of the insulation space A is controlled to increase by 1°C every two minutes until the piglets stand up, and then the temperature of the insulation space A is reduced by 1°C;

[0022] When the piglets are in a prone position and spaced apart from each other in the same thermal insulation space A, the temperature in all other thermal insulation spaces is controlled to be the same as that in the thermal insulation space A;

[0023] When the piglets are in a standing position in the same insulation space A, the temperature of the insulation space A is controlled to decrease by 1°C every two minutes until the piglets lie down, and then the temperature of the insulation space A is increased by 1°C;

[0024] When the piglets are in different postures in multiple insulation spaces, the temperature of insulation space B where the piglets are in a prone position and spaced apart is used as a reference, and the temperature in other insulation spaces is adjusted to the temperature of insulation space B.

[0025] Beneficial effects: When in use, the hot water or steam flowing inside the heating tube heats the interior of the insulation space and maintains the temperature inside the insulation space within a suitable temperature range; after the piglets enter the incubator, they can independently, actively, and freely choose a more comfortable area to sleep. Even if the piglets do not choose independently, the temperature of each insulation space can be accurately and quickly adjusted according to the piglets' position and posture, ensuring that the piglets live in a relatively comfortable environment, thereby improving the comfort of the piglets' lives. More importantly, the solution of the present invention can effectively prevent diarrhea in piglets. After a trial of 30 piglets (Gaoligong Mountain pigs) (the trial period was from the time the piglets were born to the 25th day of age), the number of piglets with diarrhea was zero; while using traditional experience, the number of piglets with diarrhea was six out of 20 piglets (Gaoligong Mountain pigs).

[0031] The following is a clear and complete description of the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example

[0033] See also Figure 1 、 Figure 2 A piglet warming device for the western Yunnan region includes a farrowing pen 1. The internal array of the farrowing pen 1 is provided with three groups of heating tubes 2. Guardrails 3 are fixedly installed on the front and back sides of the farrowing pen 1. An insulation box 4 is placed in the middle of the farrowing pen 1. A water storage cavity 5 is opened inside the insulation box 4. The insulation box 4 is located inside the water storage cavity 5 and has two groups of partitions 6 fixedly installed in the front and back distributions.

[0034] See Figure 1 、 Figure 2, the partition 6 divides the water storage chamber 5 into three insulation zones at equal intervals, and the box wall of the insulation box 4 and the heating pipe 2 together enclose three mutually connected insulation spaces, and the three insulation chambers correspond to the three groups of heating pipes 2 one by one. Entrances 7 are provided through the middle of both sides of the insulation box 4, so that piglets can enter the middle insulation chamber from the entrance 7. Installation components are provided on both sides of the insulation box 4. Multiple interface pipe sections 10 are fixedly installed on both sides of the insulation box 4, and the interface pipe sections 10 are connected to the water storage chamber 5. The interface pipe section 10 is externally connected to the heating system 1, and the heating pipe 2 is externally connected to the heating system 2. The heating system 1 and the heating system 2 are respectively connected to the control system; a piglet monitoring terminal and a temperature sensor are provided in each insulation space, and the monitoring terminal and the temperature sensor are respectively connected to the control system.

[0035] See Figure 1 、 Figure 2 The left-right portion of the heating pipe 2 is laid at the bottom of the insulation space and passes through both sides of the farrowing pen 1, and the front-back portion of the heating pipe 2 is connected between the front-back portions. The hot water or steam flowing inside the heating pipe 2 heats the interior of the insulation space to ensure the temperature inside the insulation space. Three groups of heat dissipation ports 9 are provided on the top of the insulation box 4 corresponding to the three insulation spaces. The heat dissipation ports 9 prevent the temperature inside the insulation space from being too high, ensuring ventilation and heat dissipation. A shielding door 8 is hinged inside the entrance 7 of the insulation box 4. The shielding door 10 allows piglets to enter the insulation space, and after the piglets enter the insulation space, the shielding door 10 closes the entrance 7 to ensure the temperature inside the insulation space.

[0036] See Figure 3 、 Figure 4 The mounting assembly includes an L-shaped plate 11 fixedly mounted on either side of the insulated box 4. The vertical portion of the L-shaped plate 11 has threaded holes 12, through which threaded rods 13 are threadedly connected. A turntable 14 is fixedly mounted on the end of the threaded rod 13 closest to the insulated box 4. A retaining cover 15 is positioned on the outer side of the turntable 14, and a fixing plate 16 is fixedly mounted on the surface of the retaining cover 15. The turntable 14 and the retaining cover 15 cooperate to allow relative rotation of the threaded rod 13 and the fixing plate 16. A guide rod 17 is fixedly mounted on the side of the fixing plate 16 facing away from the insulated box 4. The guide rod 17 extends through and slidably connects to the vertical portion of the L-shaped plate 11. By rotating the threaded rod 13, the distance between the fixing plate 16 and the guardrail 3 can be adjusted under the guidance of the guide rod 17. The fixing plate 16 has multiple slots 18 on the side closest to the insulated box 4. The fixing plate 16 fits against the vertical posts of the guardrail 3 through the slots 18, thereby securing the insulated box 4 between the two guardrails 3.

[0037] When in use, the thermal insulation box 4 is inserted between the two guardrails 3 distributed in the front and rear, and then the threaded rod 13 is rotated, and the threaded connection between the threaded rod 13 and the threaded hole 12 is coordinated to drive the assembly of the fixing plate 16 and the guide rod 17 close to the guardrail 3, and the fixing plate 16 is fit to the surface of the guardrail 3 through the embedded groove 18, so that the thermal insulation box 4 is fixedly installed between the two guardrails 3 in the front and rear.

[0038] A device and method for keeping piglets warm in western Yunnan according to this embodiment comprises the following steps:

[0039] Step 1: Control heating system 1 and heating system 2 to turn on, and control the temperatures in the three insulation spaces to T1°C, T2°C, and T3°C, respectively, where T1°C≠T2°C≠T3°C; T1, T2, and T3 all refer to preset initial values of the temperature, which change according to the age of the piglets. For example, when the piglets are 1 to 3 days old, the corresponding temperature is 30 to 35°C, and when the piglets are 4 to 7 days old, the corresponding temperature is 28 to 30°C;

[0040] For example, for a litter of Gaoligong Mountain piglets, the temperature distribution within the three insulation chambers was set to T1 = 32°C, T2 = 33°C, and T3 = 34°C (i.e., the initial temperature values) on the day the piglets were born. Because not every litter of piglets has the same comfortable temperature, the specific insulation temperature needs to be adjusted based on actual conditions once the piglets enter the incubator.

[0041] Step 2, obtaining the position and posture of the piglets in the heat preservation space; the postures include the posture of the piglets lying down and huddled together, the posture of the piglets lying down and spaced apart, and the posture of the piglets standing;

[0042] Step 3: Adjust the temperature of each insulation space in the incubator according to the position and posture of the piglets.

[0043] Specifically, the initial temperature value of the heat preservation space A is set to 33°C, the initial temperature value of the heat preservation space B is set to 32°C, and the initial temperature value of the heat preservation space C is set to 34°C. When the processing module of the control system executes the program, the following steps are implemented:

[0044] S1: Obtain the position and posture of the piglet in the thermal insulation space, as well as the temperature of each thermal insulation space;

[0045] S2:

[0046] When the piglets are in a prone and huddled position in the same insulation space A (this indicates that the piglets have overcooled at this temperature), the temperature of the insulation space A is controlled to increase by 1°C every two minutes until the piglets stand up, and then the temperature of the insulation space A is reduced by 1°C; if the temperature in the insulation space A rises to 35°C when the piglets stand up, it indicates that the piglets have overheated at this temperature. At this time, combined with the initial posture of the piglets, it is shown that 34°C should be the optimal comfortable temperature for these piglets. Therefore, the temperature of the insulation space A and other insulation spaces can be adjusted to 34°C;

[0047] When the piglets are in a prone position and spaced apart from each other in the same thermal insulation space A (this indicates that the piglets are comfortable at this temperature), the temperature in all other thermal insulation spaces is controlled to be the same as that in the thermal insulation space A;

[0048] When the piglets are in a standing position in the same insulation space A (this indicates that the piglets have overheated at this temperature), the temperature of the insulation space A is controlled to decrease by 1°C every two minutes until the piglets lie down, and then the temperature of the insulation space A is increased by 1°C; if the temperature in the insulation space A drops to 31°C when the piglets lie down, it indicates that the piglets have overcooled at this temperature. At this time, combined with the initial posture of the piglets, it is shown that 32°C should be the optimal comfortable temperature for these piglets. Therefore, the temperature of the insulation space A and other insulation spaces can be adjusted to 32°C;

[0049] When the piglets are in different postures in multiple insulation spaces, the temperature of the insulation space B where the piglets are in a prone and spaced-apart posture is used as a reference to adjust the temperature of the other insulation spaces to the temperature of the insulation space B; if the piglets are scattered in three insulation spaces after entering the incubator, among which the piglets in the insulation space A are in a standing posture, the piglets in the insulation space B are in a prone and spaced-apart posture, and the piglets in the insulation space C are in a prone and crowded posture, then it can be considered that the piglets in the insulation space B are in a more comfortable state. At this time, the temperatures of the insulation space A and the insulation space C can be adjusted to the temperature in the insulation space B.

[0050] The hot water or steam flowing inside the heating tube 2 heats the interior of the heat preservation space and keeps the temperature inside the heat preservation space within a suitable temperature range; after the piglets enter the heat preservation box, they can independently, actively and freely choose a more comfortable area to sleep. Even if the piglets do not choose independently, the temperature of each heat preservation space can be accurately and quickly adjusted by the piglets' position and posture to ensure that the piglets live in a relatively comfortable environment, thereby improving the comfort of the piglets' lives. More importantly, the solution of the present invention can effectively prevent piglet diarrhea. After a trial of 30 piglets (Gaoligong Mountain pigs) (the trial period was from the time the piglets were born to the 25th day of age), the number of piglets with diarrhea was zero; while using the traditional experience method (pig farming technicians adjusted the heat preservation lamp power based on experience), the number of piglets with diarrhea was six out of 20 piglets (Gaoligong Mountain pigs).
