Description

Technical Field

[0001] This utility model relates to the field of door panel technology, specifically to an infrared sensing heat-insulating door for pigsties. Background Technology

[0002] With the large-scale and modern development of the pig farming industry, environmental control in pigsties has become increasingly crucial for the healthy growth of pigs and the profitability of pig farming. Infrared sensor-operated insulated doors for pigsties have emerged to meet this need, primarily driven by practical requirements such as improving pigsty environmental management, ensuring pig welfare, and reducing farming costs.

[0003] Climate conditions vary significantly across different seasons and regions, and extreme temperatures pose a threat to the health of pigs. In cold winters, traditional pigsty doors are ineffective at preventing heat loss, leading to excessively low temperatures inside the pens. Piglets are susceptible to frostbite, their immunity decreases, and their risk of disease increases. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an infrared sensing insulation door for pigsties.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an infrared sensing heat preservation door for pigsties, comprising a heat preservation door panel body, a fixed plate slidably disposed on the inner side of the heat preservation door panel body, a first motor fixedly disposed on the inner side of the heat preservation door panel body, and a first threaded rod provided at the output end of the first motor that penetrates the fixed plate and is threadedly connected to the fixed plate.

[0008] Two second sliding grooves and positioning blocks are symmetrically arranged on the fixed plate. The positioning blocks are inserted into the second sliding grooves and slidably connected with the second sliding grooves. A second motor is provided at one end of the fixed plate. A rotating shaft is provided at the output end of the second motor. Two second threaded rods with reverse thread structure are symmetrically arranged on the rotating shaft. The two second threaded rods pass through the two positioning blocks respectively. The second threaded rods are threadedly connected to the positioning blocks.

[0009] A control module is fixedly installed on the positioning block. The control module is equipped with an infrared temperature sensor and a capture camera. An alarm is installed on the outside of the main body of the insulated door panel. The infrared temperature sensor and the alarm are connected by an electrical signal.

[0010] Furthermore, an improvement of this utility model is that the main body of the heat-insulating door panel is provided with an observation window.

[0011] To improve the stability of the fixing plate during lifting, the present invention includes the following improvements: two first sliding grooves are symmetrically arranged on the inner side of the main body of the heat-insulating door panel, and sliders that are slidably connected to the first sliding grooves are provided at both ends of the fixing plate. The cross-sections of the first sliding groove and the second sliding groove are both rectangular.

[0012] To ensure the insulation effect of the insulated door panel body, the improvement of this utility model is that the interior of the insulated door panel body is filled with insulation material, and the insulation material is polyurethane foam.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an infrared sensing insulation door for pigsties, which has the following beneficial effects:

[0015] Precise monitoring of piglet health: Random temperature checks using infrared thermometers enable the timely detection of piglets with abnormal temperatures. Simultaneously, a camera records real-time images of piglets with abnormal temperatures, providing visual evidence for disease diagnosis. This facilitates timely treatment by farm staff, reducing the risk of piglet mortality, improving the overall health of the herd, and ensuring profitability.

[0016] Effectively maintains a stable pigsty environment: The main body of the insulated door panel is filled with polyurethane foam, which has an extremely low thermal conductivity, effectively preventing heat loss and maintaining a stable temperature inside the pigsty. This reduces heat loss due to opening the door for inspection, helps lower winter heating costs, and also prevents hot outside air from entering the pigsty in summer, creating a comfortable environment for piglets to grow.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 The present invention provides an infrared sensing heat preservation door for pigsties, comprising a heat preservation door panel body 1, a fixing plate 3 slidably disposed on the inner side of the heat preservation door panel body 1, a first motor 4 fixedly disposed on the inner side of the heat preservation door panel body 1, and a first threaded rod 5 that penetrates the fixing plate 3 and is threadedly connected to the fixing plate 3 at the output end of the first motor 4.

[0024] Two second sliding grooves 8 and positioning blocks 9 are symmetrically arranged on the fixed plate 3. The positioning blocks 9 are inserted into the second sliding grooves 8 and are slidably connected with the second sliding grooves 8. A second motor 10 is provided at one end of the fixed plate 3. A rotating shaft 11 is provided at the output end of the second motor 10. Two second threaded rods 12 with reverse thread structure are symmetrically arranged on the rotating shaft 11. The two second threaded rods 12 pass through the two positioning blocks 9 respectively, and the second threaded rods 12 are threadedly connected to the positioning blocks 9.

[0025] A control module 13 is fixedly installed on the positioning block 9. The control module 13 is equipped with an infrared temperature sensor 14 and a capture camera 15. An alarm 16 is installed on the outside of the heat-insulating door panel body 1. The infrared temperature sensor 14 and the alarm 16 are connected by an electrical signal.

[0026] Principle of position adjustment of detection components:

[0027] Two first sliding grooves 6 are symmetrically arranged on the inner side of the heat-insulating door panel body 1. The two ends of the fixing plate 3 are provided with sliders 7 that are slidably connected to the first sliding grooves 6. The cross-sections of the first sliding grooves 6 and the second sliding grooves 8 are both rectangular.

[0028] In the pigsty, when it is necessary to adjust the position of the infrared temperature sensor 14 and the capture camera 15, the first motor 4 is started. The operation of the first motor 4 drives the first threaded rod 5 to rotate. Since the first threaded rod 5 is threadedly connected to the fixed plate 3, and the fixed plate 3 is slidably connected to the first sliding groove 6 on the inner side of the heat-insulating door panel body 1 through the slider 7, under the guidance of the threaded transmission and the sliding groove, the fixed plate 3 will move up and down along the inner side of the heat-insulating door panel body 1, thereby realizing the adjustment of the height of the fixed plate 3 to adapt to the detection needs of different pigsty space heights and piglet sizes.

[0029] When further adjustment of the horizontal position of the infrared temperature sensor 14 and the snapshot camera 15 is required, the second motor 10 is activated. The second motor 10 drives the rotating shaft 11 to rotate, and the second threaded rods 12 with symmetrical reverse thread structures on the rotating shaft 11 rotate accordingly. Since the two second threaded rods 12 are respectively threadedly connected to the two positioning blocks 9, and the positioning blocks 9 slide in the second sliding groove 8 on the fixed plate 3, under the action of the reverse threads, the two positioning blocks 9 will move towards or away from each other along the second sliding groove 8, thereby driving the control module 13, infrared temperature sensor 14 and snapshot camera 15 installed on the positioning blocks 9 to adjust their positions in the horizontal direction, so as to achieve coverage detection of different areas in the pigsty.

[0030] Detection and alarm principles:

[0031] After the control module 13 is started, it drives the infrared temperature sensor 14 to periodically collect body temperature data at a preset frequency. When piglets move freely in the pigpen, the infrared temperature sensor 14 randomly detects the temperature of piglets passing through its detection range. When the detected body temperature of a piglet is lower or higher than the preset value, the infrared temperature sensor 14 will immediately transmit the temperature signal to the control module 13.

[0032] After receiving an abnormal temperature signal, the control module 13 will trigger the capture camera 15 to capture an image of the piglet's current location and record the piglet's status. On the other hand, it will send an electrical signal to the alarm 16. Upon receiving the signal, the alarm 16 will sound an alarm to remind the farmers that the piglet's body temperature is abnormal so that appropriate measures can be taken in time. The captured image will be transmitted to the designated monitoring equipment.

[0033] Principles of daily observation:

[0034] The main body 1 of the insulated door panel is provided with an observation window 2.

[0035] The observation window 2 set on the main body 1 of the heat-insulating door panel allows farmers to directly observe the piglets' activities and feeding in the pigsty without opening the door, reducing the number of times the door is opened, preventing heat loss and the entry of external pathogens, and helping to maintain a stable environment in the pigsty.

[0036] The adjustable mounting plate 3 and positioning block 9 design allow the infrared temperature sensor 14 and the capture camera 15 to be flexibly positioned according to actual needs in different pigsty environments. Whether in large-scale pigsties or small-scale farms, it ensures effective monitoring of all areas within the pigsty, improving the comprehensiveness and accuracy of monitoring.

[0037] The interior of the insulated door panel body 1 is filled with insulation material, which is polyurethane foam.

[0038] The main body of the insulated door panel 1 is filled with polyurethane foam. Polyurethane foam has an extremely low thermal conductivity, which can effectively prevent heat loss and maintain a stable temperature inside the pigsty. This reduces heat loss caused by opening the door for observation, helps to lower winter heating costs, and also prevents hot outside air from entering the pigsty in summer, creating a comfortable environment for piglets to grow.

[0039] The first motor 4 and the second motor 10 can be miniature DC geared motors, such as the MH-37GB520 from Minghui Motor. This model of motor has stable speed and large torque, which can meet the requirement of driving the first threaded rod 5 to smoothly raise and lower the fixed plate 3, and the noise is low, so it will not disturb the piglets.

[0040] Infrared Temperature Sensor 14: Select the appropriate model based on the size of the pigsty. For small pigsties (area less than 100 square meters), the MLX90614 non-contact infrared temperature sensor can be used. Its measurement range is -40℃ to 125℃, with an accuracy of ±0.5℃ and an effective detection distance of 0.1 to 3 meters, which can meet the needs of detecting piglet body temperature in small pigsties. For large pigsties (area greater than 100 square meters), the Melexis MLX90640 infrared thermal imaging sensor can be selected. This sensor can achieve high-resolution temperature imaging and has a longer effective detection distance of over 5 meters, which can comprehensively monitor the body temperature of piglets in large pigsties.

[0041] Camera 15: Hikvision's DS-2CD3T47WD-L camera can be selected. It has 4 megapixels, can provide clear images, supports day and night switching function, and can capture clear images even in low-light pigsty environments, meeting the needs of capturing images of piglets' condition.

[0042] Alarm 16: The system employs an audible and visual alarm 16, which has a loud sound exceeding 120 decibels, clearly alerting pig farm workers in the pigsty environment. It is also equipped with a flashing red light to attract attention even in noisy environments.

[0043] Control Module 13: The Arduino Uno development board can be used as the core of the control module 13. It has rich interfaces, which makes it easy to connect to devices such as infrared temperature sensor 14, capture camera 15, and alarm 16. It is also easy to program and can be customized according to actual needs.

[0044] Insulated door panel body 1: The insulated door panel body 1 can adopt a double-layer galvanized steel plate structure with polyurethane foam filling the middle to ensure good thermal insulation performance.

[0045] Observation window 2: Double-layered hollow tempered glass is used, which can ensure good light transmission, making it easy to observe the situation inside the pigsty, and also has a certain heat insulation performance.
