[0002] In the case of no power supply, to study the influence of climate warming on plant physiology and ecology and carbon sink function of ecological system, the simplest and most common warming method is passive warming greenhouse or open-top chamber.This kind of warming facility has been applied in many habitats, and is particularly suitable for high latitude and high altitude areas, such as arctic and antarctic tundra, subalpine grassland, Qinghai-Tibet Plateau and temperate grassland.In general, greenhouse and open-top chamber can increase air temperature by 1-6℃.The specific temperature can be adjusted according to the purpose of experiment and actual environment.Greenhouse and open-top chamber have many materials and styles according to different research purposes, including open-top design, horticultural bell-shaped glass cover, dome-shaped tent, screen, glass greenhouse, plastic greenhouse, etc.As an economical and simple warming device, traditional greenhouse and open-top chamber are widely used in remote areas without power supply.Although it has many advantages and is widely used in climate change research, the outstanding disadvantage is that it cannot accurately control the warming amplitude, i.e.the warming amplitude varies with the changes of site conditions such as photosynthetic radiation, which leads to the following problems:

[0037] It should be noted that the features in the embodiments of the application can be combined with each other without conflict.

[0038] In the prior art, the natural warming device has single function, can achieve small experimental purpose, and obtains less experimental data, which is not conducive to subsequent experimental research.

[0039] In view of this, the designer provides a field natural warming device, which has diversified functions, can achieve various experimental purposes, has more experimental result data, and is conducive to experimental research on the influence of climate warming on plant physiology and ecology and carbon sink function of ecological system.

[0040] Please refer to Figures 1-5 The embodiment provides a field natural warming device, which comprises an adjustable warming mechanism 100 and a driving mechanism 200.

[0041] The adjustable warming mechanism 100 comprises an annular support seat 110 and an open-top chamber 120, the annular support seat 110 is used for being fixed to the ground surface, the open-top chamber 120 is provided with a planting space 123 with adjustable size, the open-top chamber 120 is installed on the annular support seat 110, and the planting space 123 is communicated with a through hole surrounded by the annular support seat 110.

[0042] The driving mechanism 200 is connected with the open-top chamber 120 and is used for driving the open-top chamber 120 to move, so as to adjust the size of the planting space 123.

[0043] As described above, the use mode of the field natural warming device provided by the embodiment is as follows:

[0044] The experimental device is installed in the set area by using the annular support seat 110, and the plants are enclosed in the planting space 123. During the experiment, the driving mechanism 200 can be started to drive the open-top chamber 120 to move, so as to adjust the volume of the planting space 123 surrounded by the open-top chamber 120, thereby adjusting the speed, temperature and the like of the warming, and further adapting to the needs of different experimental purposes. That is, not only can the temperature gradient in the field experiment be set to conduct comparative experiments, but also the warming speed and the target temperature can be adjusted according to the needs during the experiment, the flexibility of the experimental operation can be improved, various experimental parameters can be obtained, and the research for various experimental purposes is facilitated. At the same time, by adjusting the size of the planting space 123, the rainfall and snowfall conditions inside and outside the planting space 123 can be made consistent, and the error influence of the rainfall and snowfall on the experimental results can be reduced.

[0045] The following embodiments illustrate the details of the field natural warming device of the present application by way of example.

[0046] Please refer to Figure 1 In the embodiment, optionally, the field natural warming device comprises an adjustable warming mechanism 100, a driving mechanism 200, a controller 300 and a plurality of environmental monitoring sensors 400. The adjustable warming mechanism 100 is connected with the driving mechanism 200, and the plurality of environmental monitoring sensors 400 are electrically connected with the controller 300. The adjustable warming mechanism 100 can form a planting space 123 for planting plants, the driving mechanism 200 can drive the adjustable warming mechanism 100 to move, so as to adjust the volume of the planting space 123, thereby adjusting the warming speed and realizing the gradient temperature. The plurality of environmental monitoring sensors 400 are distributed on the inner side and the outer side of the planting space 123, and can monitor the environments inside and outside the planting space 123 respectively, so as to compare the environment inside the planting space 123 with the environment of the planting space 123, take the environment outside the planting space 123 as a reference, and accurately adjust the environment inside the planting space 123.

[0047] Please refer to Figures 1-3 Optionally, the adjustable warming mechanism 100 comprises an annular support seat 110, an open-top chamber 120, a plurality of fixed legs 130 and a plurality of elastic members (not shown in the figure). The open-top chamber 120 and the plurality of fixed legs 130 can be connected with the annular support seat 110. The open-top chamber 120 is located above the annular support seat 110, and the plurality of fixed legs 130 are located below the annular support seat 110. The fixed legs 130 can be inserted into the soil layer to play a fixing role. The bottom of the annular support seat 110 is in contact with the ground surface, which reduces air convection and is beneficial to temperature regulation.

[0048] For example, in some embodiments, the annular support 110 is configured as a circular structure, forming a circular through hole. Eighteen connecting pieces 140 are mounted on the top of the annular support 110, each connecting piece 140 being rotatably connected to the annular support 110. The eighteen connecting pieces 140 are evenly spaced around the circumference of the annular support 110, and each connecting piece 140 is tangent to the same circumference. The plane of this circumference is perpendicular to the axis of the annular support 110, and the center of this circumference is located on the axis of the annular support 110.

[0049] It should be noted that in other embodiments, the number of connecting pieces 140 is not limited to eighteen; they can be designed as needed. This embodiment does not exhaustively list them.

[0050] In addition, the two sides of the connecting piece 140 are fixed to the annular support 110, and the portion between the two sides of the connecting piece 140 and the annular support 110 has a gap to form a space for the installation and movement of the open-top chamber 120.

[0051] Please refer to Figure 4 Optionally, the open-top chamber 120 includes eighteen light-transmitting blades 121, all of which are mounted on the top of the annular support 110 and arranged in a ring, forming a planting space 123. It should be understood that in other embodiments, the number of light-transmitting blades 121 is not limited to eighteen; the number of light-transmitting blades 121, connecting pieces 140, and elastic elements can be equal. Each light-transmitting blade 121 is rotatably connected to the connecting piece 140. Each elastic element can be located inside the light-transmitting blade 121, with one side connected to the light-transmitting blade 121 and the other side connected to the annular support 110. The elastic element can be a compression spring, which increases the elastic force that causes the corresponding light-transmitting blade 121 to have an inward-outward rotational tendency, thereby increasing the planting space 123. That is, the elastic element enables each light-transmitting blade 121 to have an unfolding movement tendency. It should be understood that the first side 1211 of all the light-transmitting blades 121 is rotatably connected to the connecting piece 140, and the opposite second sides 1212 of all the light-transmitting blades 121 form the top opening 124 of the planting space 123. When the light-transmitting blades 121 rotate from the inside to the outside, the top opening 124 increases, the probability of rain and snow entering the planting space 123 is greater, and the amount of rain and snow in the planting space 123 can be increased. Correspondingly, the volume of the planting space 123 increases, and the heating rate slows down. When the light-transmitting blades 121 rotate from the outside to the inside, the top opening 124 decreases, the probability of rain and snow entering the planting space 123 is smaller, and the amount of rain and snow in the planting space 123 can be reduced. Correspondingly, the volume of the planting space 123 decreases, and the heating rate increases.

[0052] Optionally, the light-transmitting blade 121 can be an arc-shaped blade with a gradually changing width. The width of the first side 1211 is small, and the width of the second side 1212 is large. The first side 1211 is provided with a rotating hole 122, and the connecting piece 140 passes through the rotating hole 122. When the light-transmitting blade 121 rotates relative to the connecting piece 140, it can also adaptively slide a certain distance relative to the connecting piece 140, thereby ensuring that the adjacent light-transmitting blades 121 are in closer contact.

[0053] Please refer to Figure 4 Meanwhile, the light-transmitting blades 121 can be made of monocrystalline acrylic sheets with a light transmittance >95%, ensuring that the plants within the planting space 123 receive sufficient light. Each light-transmitting blade 121 also has an arc-shaped inner surface 1213 and an arc-shaped outer surface 1214 along its thickness direction, with the inner surfaces 1213 of all the light-transmitting blades 121 forming the planting space 123. Furthermore, in the circumferential direction, any two adjacent light-transmitting blades 121 partially overlap, meaning that the inner surfaces 1213 and outer surfaces 1214 of any two adjacent light-transmitting blades 121 are joined together. All the light-transmitting blades 121 are regularly overlapped. Specifically, in any three light-transmitting blades 121 arranged in sequence along the circumference, the outer surface 1214 of the middle light-transmitting blade 121 is attached to the inner surface 1213 of the light-transmitting blade 121 on one side, and the inner surface 1213 of the middle light-transmitting blade 121 is attached to the outer surface 1214 of the light-transmitting blade 121 on the other side. In other words, in the clockwise or counterclockwise direction, the front light-transmitting blade 121 is always located inside the adjacent rear light-transmitting blade 121, or the front light-transmitting blade 121 is always located outside the adjacent rear light-transmitting blade 121. As shown in this embodiment, in the clockwise direction, the front light-transmitting blade 121 is always located outside the adjacent rear light-transmitting blade 121. In this way, all the light-transmitting blades 121 form a linkage structure. When one of the light-transmitting blades 121 is driven to rotate, the other light-transmitting blades 121 will perform the same movement in sequence. That is, when one of the light-transmitting blades 121 rotates inward, the other light-transmitting blades 121 will also rotate inward in sequence. Similarly, when one of the light-transmitting blades 121 rotates outward, the other light-transmitting blades 121 will also rotate outward in sequence, making the operation flexible and convenient.

[0054] In this embodiment, optionally, the drive mechanism 200 includes a bracket 210 and a linear telescopic assembly. The bracket 210 is used to support the ground surface, and the linear telescopic assembly is installed on the bracket 210. The telescopic end of the linear telescopic assembly contacts the outer surface 1214 of the light-transmitting blade 121. When the linear telescopic assembly telescopically moves, it can drive the light-transmitting blade 121 to rotate.

[0055] Please refer toFigure 1 For example, in one embodiment, the linear telescopic mechanism optionally includes a servo motor 220, a lead screw 230, a first nut 240, and a second nut 250. The servo motor 220 is mounted on the bracket 210, and the output shaft of the servo motor 220 is connected to the lead screw 230, which is simultaneously screwed to the first nut 240 and the second nut 250. Correspondingly, each of the two target blades 1215 among the plurality of light-transmitting blades 121 is provided with a strip-shaped mounting hole 1216, the length direction of the strip-shaped mounting hole 1216 being the same as the bending direction of the target blade 1215, and the two target blades 1215 being arranged relatively at intervals. The lead screw 230 passes through two strip-shaped mounting holes 1216. The first nut 240 and the second nut 250 each contact the outer surface 1214 of the two target blades 1215. The first nut 240 and the second nut 250 are fixed relative to each other in the circumferential direction of the lead screw 230 by the bracket 210; that is, the first nut 240 and the second nut 250 do not rotate with the lead screw 230. Simultaneously, the width of the first nut 240 and the second nut 250 is greater than the width of the strip-shaped mounting holes 1216. The servo motor 220 drives the lead screw 230 to rotate, thereby causing the first nut 240 and the second nut 250 to move closer together. The first nut 240 and the second nut 250 push the two target blades 1215 to rotate inward synchronously. Please refer to... Figure 4 When the two target leaves 1215 rotate inward, they sequentially drive the remaining light-transmitting leaves 121 to rotate inward, thereby reducing the top opening 124 and decreasing the volume of the planting space 123. Similarly, when it is necessary to enlarge the top opening 124, the servo motor 220 rotates in the opposite direction, and the first nut 240 and the second nut 250 move away from each other. Under the action of the elastic element, the target leaves 1215 and the remaining leaves rotate outward. By controlling the distance between the first nut 240 and the second nut 250, the size of the planting space 123 can be effectively adjusted.

[0056] It should be understood that when the target blade 1215 rotates, its height changes, causing the lead screw 230 to move relative to the strip-shaped mounting hole 1216 to avoid interference between the target blade 1215 and the lead screw 230. It is worth noting that when the target blade 1215 rotates, the contact position between its outer surface 1214 and the first nut 240 and the second nut 250 also changes. By controlling the movement of the two target blades 1215 together, the efficiency of adjusting the volume of the planting space 123 can be improved.

[0057] In addition, to prevent the first nut 240 and the second nut 250 from rotating together with the lead screw 230, two guide posts can be set on the ground. One end of the two guide posts is fixed to the ground, and the other end of the two guide posts is slidably connected to the first nut 240 and the second nut 250 respectively.

[0058] Please refer to Figure 2 In another embodiment, the linear telescopic assembly includes a servo motor 220, a lead screw 230, and a force-transmitting nut 260. The servo motor 220 is mounted on a bracket 210, and its output shaft is connected to the lead screw 230. The lead screw 230 passes through and is threadedly connected to the force-transmitting nut 260. The end of the lead screw away from the servo motor 220 does not extend beyond the end of the force-transmitting nut 260 near the light-transmitting blade 121, preventing contact between the lead screw and the light-transmitting blade 121 and minimizing interference. The force-transmitting nut 260 and the bracket 210 are fixed relative to each other in the circumferential direction of the lead screw 230. For example, a guide rod 270 can be provided on the bracket 210, arranged parallel to and spaced apart from the lead screw. The guide rod 270 and the force-transmitting nut 260 are slidably engaged in the longitudinal direction of the lead screw 230, thus restricting the force-transmitting nut 260 from rotating with the lead screw 230. The force-transmitting nut 260 contacts the outer surface 1214 of the light-transmitting blade 121 and can slide relative to the light-transmitting blade 121. The servo motor 220 is used to drive the lead screw 230 to rotate, so that the force-transmitting nut 260 slides back and forth along the length of the lead screw 230. In this way, by setting a force-transmitting nut 260, the end of the force-transmitting nut 260 contacts the outer surface 1214 of the light-transmitting blade 121. The lead screw 230 does not need to penetrate the light-transmitting blade 121, and there is no need to open a strip-shaped mounting hole 1216 on the light-transmitting blade 121. The structure of the light-transmitting blade 121 is not damaged. The temperature distribution in the planting space 123 enclosed by the light-transmitting blade 121 is more uniform, and it is less likely to have large local temperature differences, resulting in better temperature control.

[0059] In this embodiment, optionally, the controller 300 can be mounted on the bracket 210. The controller 300 can communicate with the environmental monitoring sensor 400 via a wire. Furthermore, the controller 300 can communicate with a display, thereby visually reflecting environmental parameters on the display. The environmental monitoring sensor 400 may include temperature sensors and rain / snow sensors, etc., and there can be multiple temperature sensors and multiple rain / snow sensors distributed inside and outside the planting space 123. This allows for real-time acquisition of environmental parameters such as temperature and rainfall / snowfall inside and outside the planting space 123, enabling comparison and reference.

[0060] In other embodiments, the outdoor natural heating device may optionally include a solar power generation mechanism 500, which is connected to the support 210 and provides power to the controller 300 and environmental monitoring sensors 400, etc.

[0061] The experimental steps of the outdoor natural warming device provided in this embodiment include, for example:

[0062] Step 1. Install the heating device in the designated area in the field, ensuring that the equipment is installed reliably and securely, and that the control system is operating normally;

[0063] Step 2. Set the temperature increase value for the open-top chamber 120, for example, set the temperature increase value to 1~6℃;

[0064] Step 3. The temperature sensor located inside the planting space 123 reads the indoor temperature inside the open-top chamber 120, and the temperature sensor located outside the planting space 123 reads the atmospheric temperature outside the open-top chamber 120. The controller 300 calculates the actual temperature difference between the indoor and outdoor temperatures. If the actual temperature difference is less than the set temperature increase value, the drive mechanism 200 starts, driving the light-transmitting leaf 121 to rotate inward, reducing the volume of the planting space 123 and accelerating the temperature rise; conversely, the volume of the planting space 123 is increased. After a set time, such as 5 minutes, the measurement is repeated, and the adjustment of the volume of the planting space 123 is repeated until the actual temperature difference is within ±0.2℃ of the temperature increase value. Subsequently, at set intervals, such as 60 minutes, the temperature increase value and the actual temperature difference are compared. If the difference is within ±0.2℃, the drive mechanism 200 does not operate; if it exceeds this value, the top opening 124 is adjusted again.

[0065] Step 4. The rain and snow sensor installed on the controller 300 can be used to determine whether there is rain or snow. If there is rain or snow, the top opening 124 can be adjusted to be the same size as the through hole formed by the annular support 110 to ensure that the amount of rain or snow inside and outside the open top chamber 120 is consistent. After the rain or snow ends, the heating process described in step 3 is executed.

[0066] The outdoor natural warming device provided in this embodiment has diverse functions, can achieve a variety of experimental purposes, is conducive to environmental monitoring, and is helpful for studying the impact of climate warming on plant physiology and ecology as well as the carbon sink function of ecosystems.
