Description

Technical Field

[0001] This application relates to the field of environmental control equipment technology, and in particular to an OTC heating device with multiple temperature gradients. Background Technology

[0002] While existing warming experimental devices can simulate a certain temperature increase, they are insufficient in simulating multiple temperature gradients and cannot fully reflect the ecological response under different temperature conditions, which limits the depth and breadth of research.

[0003] In practical applications, common heating experimental apparatuses mainly fall into two types: open and closed. Open apparatuses typically regulate temperature through natural ventilation and are suitable for simulating lower temperature rises, while closed apparatuses increase internal temperature by reducing airflow and are suitable for simulating higher temperature rises. However, both types of apparatuses can only simulate a single temperature gradient and cannot simultaneously simulate multiple temperature conditions in the same experiment. Furthermore, some improved apparatuses attempt to change the temperature by adjusting the size or materials of the apparatus, but this still makes it difficult to achieve precise multi-gradient temperature control.

[0004] The aforementioned technologies cannot simultaneously simulate multiple temperature gradients in a single experiment, resulting in insufficient representativeness of the experimental results and making it difficult to comprehensively assess the ecological response under different temperature conditions. This limitation severely affects the accuracy and application scope of the research, urgently requiring a heating device capable of simulating the characteristics of multiple temperature gradient environments in a single experiment. Utility Model Content

[0005] To overcome the above problems, this application provides an OTC heating device with multiple temperature gradients.

[0006] The OTC heating device with multiple temperature gradients provided in this application adopts the following technical solution:

[0007] A multi-temperature gradient OTC heating device includes a support assembly and a measuring assembly. The support assembly includes at least two frames and multiple enclosures. Two of the frames are fixed at a designated location in the farmland. One of the frames is not equipped with any enclosures. The remaining sides of the other frame that are not in contact with the farmland correspond to one enclosure. The enclosures and the frames form an OTC heating hood. The enclosures on the four side walls of the OTC heating hood are each provided with multiple air vents.

[0008] The measuring component includes multiple temperature measuring elements, each corresponding to one of the frames. The temperature measuring elements are connected within the frames and are used to monitor the temperature and humidity changes of the device.

[0009] By adopting the technical scheme, one of the frames is not provided with a fence, the temperature condition in the natural environment is simulated, and the comparison basis of the experiment is ensured. The OTC warming device with multiple temperature gradients can realize accurate control of multiple temperature gradients through different fence designs and air hole configurations, so as to simulate ecological responses under different temperature conditions in the same experiment. This design not only improves the diversity and reliability of experimental data, but also simplifies the experimental operation process and reduces the experimental cost, and can simulate multiple temperature gradient environments in the same experiment. In addition, by comparing the temperature and humidity changes under different temperature conditions, researchers can more accurately evaluate the specific effects of temperature rise on crop growth and ecological environment.

[0010] In a specific implementable scheme, the frame is provided with five OTC warming covers, which can be divided into a full-open blank control device, a low-warming device with 15 equidistant holes, a medium-warming device with 10 equidistant holes, a high-warming device with 5 equidistant holes, and a full-warming device without holes. The low-warming device with 15 equidistant holes is provided with 15 equidistant air holes on the fence of the four side walls of the OTC warming cover. The medium-warming device with 10 equidistant holes is provided with 10 equidistant air holes on the fence of the four side walls of the OTC warming cover. The high-warming device with 5 equidistant holes is provided with 5 equidistant air holes on the fence of the four side walls of the OTC warming cover. The full-warming device without holes has no holes.

In this way, multiple temperature gradients can be simulated in the same experiment, so as to comprehensively evaluate the ecological responses under different temperature conditions, improve the accuracy and reliability of the experiment, and reduce the experimental cost and time.

[0012] In a specific implementable scheme, the temperature measuring member includes a steel wire rope and three temperature and humidity sensors. The steel wire rope is fixed in the OTC warming cover, and the steel wire rope is arranged along the diagonal line of each OTC warming cover for fixing the temperature and humidity sensors. The three temperature and humidity sensors are uniformly and spacedly arranged along the length direction of the steel wire rope.

[0013] By adopting the above technical scheme, the stability and fixation of the temperature and humidity sensor in the OTC warming cover can be ensured, the position deviation of the sensor caused by wind blowing or other factors can be avoided, and the accuracy and stability of temperature and humidity data acquisition can be improved; the three temperature and humidity sensors are arranged at different height positions in the OTC warming cover, the temperature and humidity changes in the OTC warming cover can be comprehensively monitored, and the comprehensiveness and reliability of experimental data can be ensured.

[0015] By adopting the above technical scheme, the phenology camera is arranged at the periphery of the OTC warming device and is used for recording the growth of plants, the support frame is connected to the phenology camera, and the support frame is connected to the farmland. This scheme can monitor and record the growth state of plants under different temperature gradients in real time, provide intuitive data support, help researchers comprehensively understand the specific influence of different temperature conditions on plant growth, and improve the accuracy and reliability of experiments.

[0016] In a specific implementable scheme, the auxiliary heating assembly further comprises at least one heating member, the heating member comprises an electric heating wire, the electric heating wire is located in the OTC warming cover, and the electric heating wire is connected to the fence and is used for heating in the OTC warming cover.

[0017] By adopting the above technical scheme, this scheme realizes precise temperature control, ensures that the temperature in each OTC warming cover can be independently adjusted, thereby simultaneously simulating multiple temperature gradients in the same experiment, and improves the precision and reliability of the experiment. In addition, by heating through the electric heating wire, the influence of natural environmental temperature fluctuations can also be effectively solved, so that the experimental results are more stable and consistent.

[0018] In a specific implementable scheme, the auxiliary heating assembly further comprises a detection member, the detection member is a temperature sensor, the temperature sensor is screw-fixed in the OTC warming cover, the temperature sensor is electrically connected with the electric heating wire, a preset temperature value of the temperature sensor is set by a person, when the temperature detected by the temperature sensor reaches the preset value, the temperature sensor controls the electric heating wire to stop heating, so as to maintain the stability of the temperature in the OTC warming cover.

[0019] By adopting the above technical scheme, when the temperature reaches the preset value, the temperature sensor will automatically control the electric heating wire to stop heating, so as to maintain the stability of the temperature; this closed-loop control system effectively avoids the influence of temperature fluctuations on experimental results, improves the repeatability and consistency of experiments, and makes the experimental results more convincing.

[0020] In a specific implementation, the heating element further comprises a contact plate connected to the electric heating wire near the side of the OTC heating cover side wall, and the contact plate is fixed to the OTC heating cover side wall.

[0021] By adopting the above technical solution, the direct contact between the electric heating wire and the enclosure is effectively avoided, preventing the enclosure from being damaged due to high temperature, and ensuring the reliability and safety of the experiment. In addition, the fixing mode of the contact plate can also enhance the stability of the electric heating wire, reduce the displacement of the electric heating wire caused by external factors, and further improve the accuracy and consistency of temperature control.

[0022] In a specific implementation, four heating elements are provided, each corresponding to one OTC heating cover side wall, and the electric heating wires on the OTC heating cover side wall are arranged in an M shape.

[0023] By adopting the above technical solution, the electric heating wires are arranged in an M shape on the side wall, which effectively avoids the shielding of the air holes and ensures the normal ventilation function of the air holes, so as to not affect the accurate control of the temperature gradient; at the same time, the four heating elements can uniformly heat the space inside the OTC heating cover, improve the heating efficiency, and ensure the uniformity and stability of the temperature, further enhancing the reliability and repeatability of the experimental results.
