Description

Technical Field

[0001] The present invention relates to the technical field of outdoor warming, and in particular to a outdoor natural warming device. Background Art

[0002] In the absence of electricity, the simplest and most common warming method for studying the effects of climate warming on plant physiology and ecosystem carbon sequestration is a passively heated greenhouse or open-top chamber. These warming devices have been used in a variety of habitats and are particularly well-suited to high-latitude and high-altitude regions, such as the Arctic and Antarctic tundra, subalpine grasslands, the Qinghai-Tibet Plateau, and temperate steppes. Generally, greenhouses and open-top chambers can increase air temperature by 1–6°C. The specific temperature should be adjusted based on the experimental objectives and the actual environment. Greenhouses and open-top chambers come in a variety of materials and styles, depending on the research purpose, including open-top designs, horticultural bell-shaped glass covers, dome-shaped tents, screen-style greenhouses, glass greenhouses, and plastic greenhouses. Traditional greenhouses and open-top chambers are economical and simple warming devices and are widely used in remote areas without electricity. Despite their many advantages and widespread use in climate change research, a significant drawback is the inability to precisely control the magnitude of warming. The magnitude of warming varies with site conditions such as photosynthetic radiation. This limitation leads to the following problems:

[0003] 1. Average warming values are often used to roughly quantify the extent of warming, lacking strong data support for scientific inferences;

[0004] 2. It is impossible to set a specific temperature according to the needs of scientific researchers;

[0005] 3. Traditional heating devices are almost unable to achieve the temperature gradient setting in field experiments for comparative experiments;

[0006] 4. They cannot simulate the diurnal variations in temperature under global warming conditions. Furthermore, traditional greenhouses and open-top chambers can hinder the fall of rain and snow, restrict the diffusion and turbulence of mixed gases, and inhibit the rise of water vapor during the day and the formation of dew at night.

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

[0040] Please refer to Figure 1-Figure 5 This embodiment provides a field natural heating device, including an adjustable heating mechanism 100 and a driving mechanism 200, wherein:

[0041] The adjustable heating mechanism 100 includes an annular support base 110 and an open-top chamber 120. The annular support base 110 is used to be fixed to the ground surface. The open-top chamber 120 is provided with a planting space 123 of adjustable size. The open-top chamber 120 is mounted on the annular support base 110. The planting space 123 is connected to the through hole surrounded by the annular support base 110.

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

[0043] As described above, the outdoor natural heating device provided in this embodiment is used as follows:

[0044] The experimental device is installed in the set area using the annular support base 110, and the plants are surrounded in the planting space 123. During the experiment, the driving mechanism 200 can be started, and the driving mechanism 200 can be used to drive the open-top chamber 120 to move, and the volume of the planting space 123 surrounded by the open-top chamber 120 can be adjusted to achieve the adjustment of the heating speed, temperature, etc., and thus adapt to the needs of different experimental purposes. That is, during the experiment, not only can the temperature gradient setting in the field experiment be achieved to conduct comparative experiments, but the heating speed and target temperature can also be adjusted according to needs, which can improve the flexibility of the experimental operation, and can obtain a variety of experimental parameters, which is conducive to the study of a variety of experimental purposes. At the same time, by adjusting the size of the planting space 123, the conditions of rainfall and snowfall inside and outside the planting space 123 can also be made consistent, reducing the error effect of rainfall and snowfall on the experimental results.

[0045] The following embodiments illustrate the details of the outdoor natural heating device of the present application by way of examples.

[0046] Please refer to Figure 1 In this embodiment, optionally, the outdoor natural warming device includes 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 to the driving mechanism 200, and the plurality of environmental monitoring sensors 400 are electrically connected to the controller 300. The adjustable warming mechanism 100 can form a planting space 123 for planting plants, and 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 heating rate and achieving gradient temperature. The plurality of environmental monitoring sensors 400 are distributed on the inside and outside of the planting space 123, and can monitor the environment inside and outside the planting space 123 respectively, thereby comparing the environment inside the planting space 123 with the environment of the planting space 123, and taking the environment outside the planting space 123 as a reference to accurately adjust the environment inside the planting space 123.

[0047] Please refer to Figure 1-Figure 3 Optionally, the adjustable temperature-increasing mechanism 100 includes an annular support base 110, an open-top chamber 120, multiple fixing legs 130, and multiple elastic members (not shown). The open-top chamber 120 and multiple fixing legs 130 can both be connected to the annular support base 110. The open-top chamber 120 is located above the annular support base 110, and the multiple fixing legs 130 are located below the annular support base 110. The fixing legs 130 can be inserted into the soil layer to provide a fixed position. The bottom of the annular support base 110 is in contact with the ground surface, reducing air convection and facilitating temperature control.

[0048] For example, in some embodiments, the annular support base 110 is configured as an annular structure, and the annular support base 110 is surrounded by a circular through hole. Eighteen connecting pieces 140 are installed on the top of the annular support base 110, each connecting piece 140 is rotatably connected to the annular support base 110, and the eighteen connecting pieces 140 are evenly spaced and arranged in the circumferential direction of the annular support base 110. Each connecting piece 140 is tangent to the same circumference, the plane of the circumference is perpendicular to the axis of the annular support base 110, and the center of the circumference is located on the axis of the annular support base 110.

[0049] It should be noted that, in other embodiments, the number of connecting pieces 140 is not limited to eighteen, and can be designed as needed, and is not exhaustively listed in this embodiment.

[0050] In addition, both sides of the connecting piece 140 are fixed on the annular support base 110 , and a portion between the two sides of the connecting piece 140 and the annular support base 110 is spaced apart 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, which are all mounted on the top of the annular support seat 110 and arranged in an annular shape. The eighteen light-transmitting blades 121 enclose a planting space 123. It should be understood that in other embodiments, the number of light-transmitting blades 121 is not limited to eighteen, and the number of light-transmitting blades 121, connecting pieces 140, and elastic members can be equal. Each light-transmitting blade 121 is rotatably connected to the connecting piece 140, and each elastic member can be located on the inner side of the light-transmitting blade 121, with one side of each elastic member connected to the light-transmitting blade 121 and the other side of each elastic member connected to the annular support seat 110. The elastic member can be a compression spring, which can increase the elastic force that causes the corresponding light-transmitting blade 121 to have a rotation tendency from the inside to the outside, so as to increase the planting space 123. That is, the elastic member can cause each light-transmitting blade 121 to have a movement tendency to expand. It should be understood that the first side 1211 of all the light-transmitting blades 121 are rotatably connected to the connecting piece 140, and the opposite second sides 1212 of all the light-transmitting blades 121 form a 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, and the probability of rain and snow entering the planting space 123 is high, which can increase the amount of rain and snow in the planting space 123. 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, and the probability of rain and snow entering the planting space 123 is small, which can reduce the amount of rain and snow in the planting space 123. 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, and the width of the light-transmitting blade 121 is gradual, 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 is passed 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 adjacent light-transmitting blades 121 are in closer contact.

[0053] Please refer to Figure 4 At the same time, the light-transmitting blades 121 can be made of a single-crystal acrylic sheet with a light transmittance greater than 95%, ensuring that the plants in the planting space 123 receive sufficient light. Furthermore, each light-transmitting blade 121 has a curved inner side surface 1213 and a curved outer side surface 1214 in the thickness direction thereof. The inner side surfaces 1213 of all light-transmitting blades 121 enclose the planting space 123. Furthermore, in the circumferential direction, any two adjacent light-transmitting blades 121 partially overlap, meaning that the inner side surfaces 1213 and outer side surfaces 1214 of any two adjacent light-transmitting blades 121 overlap. All the light-transmitting blades 121 are regularly overlapped together. Specifically, in the circumferential direction, among the three light-transmitting blades 121 arranged in sequence, the outer side surface 1214 of the light-transmitting blade 121 in the middle is aligned with the inner side surface 1213 of the light-transmitting blade 121 on one side, and the inner side surface 1213 of the light-transmitting blade 121 in the middle is aligned with the outer side surface 1214 of the light-transmitting blade 121 on the other side. In other words, in the clockwise or counterclockwise direction, the light-transmitting blade 121 in the front is always located on the inner side of the light-transmitting blade 121 adjacent to it at the rear, or the light-transmitting blade 121 in the front is always located on the outer side of the light-transmitting blade 121 adjacent to it at the rear. As shown in this embodiment, in the clockwise direction, the light-transmitting blade 121 in the front is always located on the outer side of the light-transmitting blade 121 adjacent to it at the rear. 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, which makes the operation flexible and convenient.

[0054] In this embodiment, the drive mechanism 200 optionally includes a bracket 210 and a linear telescopic assembly. The bracket 210 is supported on the ground. The linear telescopic assembly is mounted 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 telescopes, it can drive the light-transmitting blade 121 to rotate.

[0055] Please refer to Figure 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 screwed to the first nut 240 and the second nut 250. Correspondingly, two target blades 1215 among the plurality of light-transmitting blades 121 are each provided with a strip-shaped assembly hole 1216. The length direction of the strip-shaped assembly hole 1216 is the same as the curvature direction of the target blade 1215, and the two target blades 1215 are arranged with a relative spacing. The lead screw 230 is simultaneously passed through the two strip-shaped assembly holes 1216, and the first nut 240 and the second nut 250 are respectively in contact with the outer side surfaces 1214 of the two target blades 1215. The first nut 240 and the second nut 250 are relatively fixed in the circumferential direction of the lead screw 230 by the bracket 210, that is, the first nut 240 and the second nut 250 will not rotate with the lead screw 230. At the same time, the width of the first nut 240 and the second nut 250 is greater than the width of the strip-shaped assembly hole 1216. The servo motor 220 is used to drive the lead screw 230 to rotate, thereby driving the first nut 240 and the second nut 250 to approach each other, and the first nut 240 and the second nut 250 push the two target blades 1215 to rotate inward synchronously. Please combine Figure 4 When the two target blades 1215 rotate inward, they in turn drive the remaining light-transmitting blades 121 to rotate inward, thereby reducing the top opening 124 and the volume of the planting space 123. Similarly, when the top opening 124 needs to be expanded, the servo motor 220 rotates in the opposite direction, and the first and second nuts 240 and 250 move away from each other. Under the action of the elastic member, the target blades 1215 and the remaining blades rotate outward. By controlling the distance between the first and second nuts 240 and 250, the size of the planting space 123 can be effectively adjusted.

[0056] It should be understood that as the target blade 1215 rotates, the height of the target blade 1215 changes, so the lead screw 230 moves relative to the strip-shaped assembly hole 1216 to prevent interference between the target blade 1215 and the lead screw 230. Notably, as the target blade 1215 rotates, the contact position between the outer surface 1214 of the target blade 1215 and the first nut 240 and the second nut 250 also changes. By controlling the simultaneous movement of the two target blades 1215, the efficiency of adjusting the volume of the planting space 123 can be improved.

[0057] In addition, in order to prevent the first nut 240 and the second nut 250 from rotating with the screw 230, two guide columns can be set on the ground, one end of the two guide columns is fixed to the ground, and the other ends of the two guide columns are respectively slidably connected to the first nut 240 and the second nut 250.

[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 transmission nut 260. 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. The lead screw 230 is passed through the force transmission nut 260 and is threadedly connected to the force transmission nut 260. The end of the lead screw away from the servo motor 220 does not extend out of the end of the force transmission nut 260 close to the light-transmitting blade 121. The lead screw does not contact the light-transmitting blade 121 and is unlikely to interfere. The force transmission nut 260 and the bracket 210 are relatively fixed in the circumferential direction of the lead screw 230. For example, a guide rod 270 can be provided on the bracket 210. The guide rod 270 is arranged parallel to the lead screw and spaced apart. The guide rod 270 and the force transmission nut 260 are slidably matched in the length direction of the lead screw 230. In this way, the force transmission nut 260 can be restricted from rotating together with the lead screw 230. The force transmission nut 260 is in contact with the outer side 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 transmission nut 260 slides back and forth along the length direction of the lead screw 230. In this way, by providing a force transmission nut 260, the end of the force transmission nut 260 is in contact with the outer side surface 1214 of the light-transmitting blade 121, the lead screw 230 does not need to pass through the light-transmitting blade 121, and there is no need to open the strip assembly hole 1216 on the light-transmitting blade 121, which will not damage the structure of the light-transmitting blade 121. The temperature distribution in the planting space 123 surrounded by the light-transmitting blade 121 is more uniform, and it is less likely to have large local temperature differences, and the temperature control effect is good.

[0059] In this embodiment, optionally, the controller 300 can be mounted on the bracket 210. The controller 300 can be connected to the environmental monitoring sensor 400 through an electric wire. In addition, the controller 300 can be connected to the display for communication, so that the environmental parameters can be intuitively reflected through the display. Among them, the environmental monitoring sensor 400 may include a temperature sensor and a rain and snow sensor, etc. The number of temperature sensors and rain and snow sensors can be multiple, and multiple temperature sensors are distributed inside and outside the planting space 123, and multiple rain and snow sensors are distributed inside and outside the planting space 123. The environmental parameters such as temperature and rainfall and snowfall inside and outside the planting space 123 can be obtained in real time, and can be compared and referenced.

[0060] In other embodiments, optionally, the outdoor natural warming device further includes a solar power generation mechanism 500 , which is connected to the bracket 210 , and provides power to the controller 300 and the environmental monitoring sensor 400 .

[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 securely installed and the control system operates normally.

[0063] Step 2. Set the temperature increase value of the open top chamber 120, for example, the temperature increase value is set to 1 to 6°C;

[0064] Step 3. The temperature sensor located in the planting space 123 reads the indoor temperature in 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, and the controller 300 calculates the actual temperature difference between the indoor temperature and the outdoor temperature. If the actual temperature difference is less than the set warming value, the drive mechanism 200 starts, driving the light-transmitting blades 121 to rotate inward, reducing the volume of the planting space 123 and accelerating the temperature rise; otherwise, the volume of the planting space 123 is increased. Measure again after a set time, such as 5 minutes, and repeat the above-mentioned adjustment of the volume of the planting space 123 until the actual temperature difference is within the range of ±0.2°C of the warming value. Thereafter, at set intervals such as 60 minutes, compare the warming value with the actual temperature difference. If the difference between the two is within the range of ±0.2°C, the drive mechanism 200 will not act. If it exceeds this value, the top opening 124 will be adjusted again;

[0065] Step 4. The rain and snow sensor installed on the controller 300 can be used to determine whether rain or snow is falling.
