Description

Technical Field

[0001] The present invention relates to the technical field of agricultural test equipment, and in particular to a field open-type temperature-increasing test device and an installation method thereof. Background Art

[0002] Current research on agricultural water management focuses primarily on current climate conditions. However, among the many challenges of global climate change, global warming is an undeniable reality, and the trend continues. Records indicate an average annual surface temperature increase of 0.26°C per decade, exceeding the global average for the same period (0.15°C per decade). Climate warming will inevitably alter the physiological mechanisms and water use processes of many crops, but the impact of climate warming on the production of major crops remains unclear. Therefore, in response to the current reality of global warming and the need to ensure food security, research is crucial to uncovering the physiological responses of major crops, such as rice, to climate warming, characterizing the impacts of climate warming on their yield and water use efficiency, assessing the impacts of different planting and management practices on the water use efficiency of different crops under future climate warming scenarios, and proposing adaptive strategies. This process inevitably requires comprehensive field observation tests of various types. However, most closed or semi-closed test environments are quite different from the natural ecological environment conditions. Therefore, creating a micro-domain ecological environment that simulates future climate warming and conducting temperature increase simulation tests is very necessary to obtain data that is closer to the actual situation. However, there is currently a lack of a highly adaptable open test platform warming simulation device. Summary of the Invention

It can also adjust the height of the heat source as the plant height changes due to changes in the crop growth period. It is particularly suitable for conducting field experiments related to crop growth responses under future conditions of simulated climate warming. Moreover, the entire test device has a simple structure, good flexibility, and is easy to install and use. It can be set up and tested in an outdoor open field for convenience.

[0042] The arrangement of multiple wind rods 1 can form an overall framework of the plant, and the first clamping plate can conveniently support the combined bracket 3; for multiple wind rods 1, the multiple first clamping plates 2 arranged at intervals up and down can allow the multiple first clamping plates located on the same horizontal plane to form a mounting layer, and the combined bracket 3 can be stably supported by this mounting layer.

[0043] The infrared radiation heating assembly 4 can heat the plants and fields below to simulate climate warming. The canopy temperature sensor 6 is used to monitor the temperature of the canopy in the test area so as to accurately and scientifically control the temperature.

[0044] The arrangement of the combined bracket 3 and the connecting rod assembly 5 can form a shelf for mounting the infrared radiation heating assembly and the canopy temperature sensor. The detachable connection facilitates their installation and disassembly, and their status can be adjusted at any time according to actual conditions. The arrangement of the second clamping plate 7 also helps the canopy temperature sensor 6 to adjust the angle of its probe.

[0045] Further, combined Figure 3A wind pole foundation 11 is provided below the wind pole 1. The wind pole foundation 11 is formed by pouring cement on the outside of a foundation skeleton. The foundation skeleton includes a steel cage 1101 and a plurality of anchor bolts 1102 connected to the steel cage 1101. The anchor bolts 1102 are connected to a positioning plate 1103 on the upper surface of the wind pole foundation. The anchor bolts 1102 extend out of the cement and connect to the wind pole 1.

[0046] The wind mast foundation 11 facilitates the installation of the wind mast, providing a reliable and stable mounting base for the wind mast, preventing field soil instability from destabilizing the entire device and affecting the test. The steel cage 1101 and the anchor bolts 1102, combined with the cement, provide high strength and stability. The anchor bolts 1102 are pre-embedded in the cement, with the portion extending upwards directly connecting to the wind mast 1. The positioning plate 1103 is provided on the upper surface of the cement, allowing for easy docking with the bottom of the wind mast.

[0047] Further, combined Figure 4 and Figure 5 As shown, the first card plate 2 is a tree-branch-shaped card plate, including a first card plate body 201 with a "U"-shaped cross-section, and the upper and lower plates of the first card plate body 201 are provided with a clamping groove 202, and the clamping groove 202 is clamped and connected to the wind rod 1 and connected to the side wall of the first card plate body 201 through a "U"-shaped bolt; the side wall of the first card plate body 201 is also provided with an upwardly inclined limit support rod 203.

[0048] The first clip 2 is designed to be shaped like a branch, allowing it to be mounted on the wind pole like a branch and providing space for the steel pipe to be installed to support the combined bracket. The first clip body, with its slotted opening on one side, can be aligned with the wind pole and then fastened with a U-shaped bolt for complete fixation, making operation very simple and convenient. The upwardly tilted limit rod 203 forms a support and installation space with the first clip body. This U-shaped bolt is used at multiple connection points in this device.

[0049] Further, combined Figure 6 As shown, the combined bracket 3 includes a rectangular frame formed by overlapping multiple steel pipes 301 through vertical pipe sleeves 8, and a pair of symmetrical inclined steel pipes 302 are also provided on the rectangular frame, and the inclined steel pipes 302 are connected to the rectangular frame through a cross-lap assembly 9; the infrared radiation heating assembly 4 is respectively installed under the steel pipe 301 and the inclined steel pipe 302; the steel pipe 301 is also provided with a limiting groove 303 near the end position, and the setting of the limiting groove 303 is coordinated with the upper limit support rod 203 on the first clamping plate. Through its limitation, the axial movement of the steel pipe can be avoided, and its falling can also be avoided.

[0050] In this embodiment, the combined bracket 3 is constructed from six overlapping steel tubes, forming an overall "four" shape. The outer portion is formed by four overlapping steel tubes in a rectangular arrangement, with vertical tube sleeves 8 used at the overlapped joints. Inside the rectangle, two inclined steel tubes are stacked in an "eight" shape, with the minor axis as the axis of symmetry. The overlapped joints are secured by a cross-lap mechanism. This connection method creates the desired heating environment above the test area, provides convenient overlap, and offers excellent stability.

[0051] Furthermore, the vertical pipe sleeve 8 includes a first sleeve 801 and a second sleeve 802 vertically connected, and the first sleeve 801 and the second sleeve 802 are respectively connected to the steel bars in two directions, and the sides of the first sleeve 801 and the second sleeve 802 are also respectively provided with locking screws; this vertical 90° pipe sleeve can conveniently connect vertical and horizontal pipes, and can be locked in the required position with the help of the locking screws.

[0052] Combine Figure 7 and Figure 8 As shown, the cross-lap assembly 9 includes a cross-lap plate 901, and the cross-lap plate 901 is provided with grooves 902 and notches 903 in two vertical directions. In this way, the grooves 902 and notches 903 can be used to cooperate with the steel pipes, and can stably carry the steel pipes to be cross-lapped. In combination with the "U"-shaped bolts in the two vertical directions, the steel pipes in the two directions can be fastened together.

[0053] Further, combined Figure 10 and Figure 11 As shown, the infrared radiation heating component 4 includes a closed stainless steel lampshade 401, in which an infrared radiation heating tube 402 is provided. The stainless steel lampshade 401 is connected to the combined bracket 3 through a plurality of tail clamps 10; a plurality of the infrared radiation heating components 4 form at least one group of triangular heating lamps, and the plurality of the infrared radiation heating tubes 402 are all arranged horizontally.

[0054] In this embodiment, the stainless steel lampshade 401 is a four-sided, enclosed regular triangular prism with its open side facing downward. The infrared radiation heating tube 402 is horizontally fixed across the interior of the lampshade. The upper portion of each lampshade is vertically suspended below the steel pipe of the assembly bracket 3 via two of the aforementioned tail clamps 10, forming a triangular heating lamp assembly. Furthermore, to ensure consistent height between each lampshade in the triangular heating lamp assembly, the tail portion of the tail clamp 10 connecting the two lampshades below the hypotenuse of the triangle is 30 mm longer than the tail portion of the tail clamp 10 connecting the lampshade below the base of the triangle.

[0055] Furthermore, the connecting rod assembly 5 includes a horizontal long rod 501 overlapped on the combined bracket 3 through a cross-lap assembly 9. One end of the horizontal long rod 501 extends out of the combined bracket and is connected to a vertical short rod 502 through a vertical pipe sleeve 8. The vertical short rod 502 is connected to the second clamping plate 7 through a "U"-shaped bolt. Through such an arrangement, the canopy temperature sensor 6 can be arranged on the periphery of the combined bracket 3 to avoid the canopy temperature sensor 6 being directly in the triangular heating lamp group, and the area scanned by the sensor probe covers the test area as much as possible, so that it can complete the test while avoiding high-temperature heating of the sensor body.

[0056] Further, combined Figure 12 As shown, the second clamping plate 7 is an angled clamping plate, which is an obtuse-angled "V"-shaped panel as a whole. One page is provided with grooves and holes for connecting the connecting rod assembly, and the other page is provided with a pair of centrally symmetrical arc-shaped hole rails 12 for matching another "U"-shaped bolt to connect the canopy temperature sensor 6. The angle between the sensor probe of the canopy temperature sensor 6 and the vertical is 38°~39°.

[0057] The second clamping plate 7 is in the form of an angled clamping plate, which can form an angled installation structure. Combined with the arrangement of a pair of arc-shaped hole rails 12, the angle and orientation of the connected canopy temperature sensor can be adjusted.

[0058] In this embodiment, the canopy temperature sensor 6 is fixed to a page of the angled card plate with an arc-shaped hole rail by a "U"-shaped bolt, and the sensor probe is facing the side of the triangular heating lamp group. Taking the vertical distance of the sensor probe from the canopy surface as 1.2m as an example, the vertical angle of the sensor is preferably maintained at 38°~39°.

[0059] A method for installing a field open-type warming test device, the method comprising the following steps:

[0060] Before installing this device, you need to find a suitable installation location, such as a place with convenient electricity access or a place that is not prone to soil erosion. Places that are shaded all year round or close to rivers should not be selected.

[0061] Step 1: During installation, select a rectangular temperature increase test area, dig a foundation pit with a length of 300mm, a width of 300mm and a depth of 400mm at each of the four corners of the rectangular temperature increase test area, and set up a template in it.

[0062] Step 2: Setting a wind pole foundation 11 in the foundation pit, and installing one wind pole 1 on each wind pole foundation 11;

[0063] Specifically, the positioning plate 1103 and the anchor bolt 1102 are connected according to Figure 2The method shown (the anchor bolts are located at the four corners of the positioning plate) is fully welded, and round steel is used to surround the four anchor bolts 1102 to form a steel cage 1101, which is welded to the anchor bolts 1102, and the surface is hot-dip galvanized to obtain a foundation skeleton. Then, the foundation skeleton is placed in the middle of the foundation pit, and the anchor bolts are exposed with a 45mm height thread and then cement is poured to ensure that the upper surface of the positioning plate 1103 is flush with the upper surface of the cement platform. The installation of the wind pole foundation 11 is completed; then the wind pole 1 is fixed to the wind pole foundation 11 in sequence through the reserved threads on the surface of the wind pole foundation.

[0064] Step 3: Arrange a plurality of first clamping plates 2 at intervals on the wind pole 1, and the first clamping plates 2 on each wind pole 1 and located on the same horizontal plane form a mounting layer;

[0065] Specifically, the clamping groove 202 of the first clamping plate body 201 abuts against one side of the wind rod 1, and the outer periphery of the other side of the wind rod 1 is clamped with a "U"-shaped bolt and then connected and fixed with the first clamping plate body 201, so that the limiting support rod 203 on it is tilted upward.

[0066] Step 4: Place the combined bracket 3 on the installation layer, hang the infrared radiation heating component 4 below the combined bracket 3, and form a triangular heating lamp group, and the projection area below the triangular position belongs to the heating core area;

[0067] Specifically, the infrared radiation heating tube 402 is inserted and fixed in the stainless steel lampshade 401 to form a heating lamp; the four external steel pipes are first overlapped in a rectangular shape through the vertical pipe sleeve 8, and then the two oblique steel pipes are obliquely overlapped on the upper part of the long side steel pipe in an "eight" shape with the short axis of the rectangular frame as the symmetry axis, and the overlap is connected and fixed by the cross overlap assembly 9; after the combination bracket 3 is assembled, the heating lamps can be hung under the combination bracket 3 in turn through the tail clamp pipe clamp 10 to form a triangular heating lamp group, and the projected area below the triangle belongs to the heating core area.

[0068] Step 5: Install the connecting rod assembly 5 on the combined bracket 3, and connect the canopy temperature sensor 6 to the part of the connecting rod assembly 5 located on the periphery of the combined bracket through the second clamping plate 7. By rotating the second clamping plate, adjust the sensor probe to face the central axis of the triangular heating lamp group (heating core area). The effective projection area of ​​the light beam of the canopy temperature sensor on the horizontal plane is elliptical and does not exceed the boundary of the rectangular warming test area below.

[0069] Specifically, the groove surface of the angled card plate is fixed to the vertical short rod 502 of the connecting rod assembly 5 by using a "U"-shaped bolt, and at this time the angled card plate has the rotational freedom of rotation adjustment with the vertical short rod as the center, and then the canopy temperature sensor 6 is fixed to a page of the angled card plate with an arc-shaped hole rail by using a "U"-shaped bolt, and the angle and orientation of the canopy temperature sensor are adjusted by rotating the angled card plate; the canopy temperature sensor 6 measures the canopy temperature of the target area by infrared beam radiation, and the angle of the infrared beam emitted by the sensor probe is 44°, so when the canopy temperature sensor 6 is placed at a certain angle, its effective projection area on the horizontal plane is an ellipse, in order to ensure that the effective area of ​​the light beam projected to the target canopy is as large as possible and does not exceed the boundary of the test area below, taking the vertical distance of the sensor probe to the canopy surface as 1.2m as an example, it is calculated that the vertical angle of the sensor should be maintained at 38°~39°.

[0070] The infrared radiation heating component is turned on to increase the temperature of the test area, and the canopy temperature is measured through the canopy temperature sensor. The data is transmitted back to the data collector in the control cabinet to record the data in real time. The temperature increase amplitude is controlled by instructions, and the instructions at least include: setting the target temperature increase amplitude to be 2°C higher than the background temperature. When the average temperature increase amplitude is greater than 2°C, the power of the infrared radiation heating component is automatically reduced to reduce the temperature increase amplitude until the average temperature increase level returns to 2°C, and vice versa. In addition, as the crop growth period changes, the canopy surface level will also increase with the increase in plant height. It is preferred to maintain the distance between the heat source and the canopy surface level at 1m to 1.3m. When the canopy surface level is raised to a distance less than 1m from the heating lamp group, the combination bracket 20 can be lifted to a higher level of the installation layer composed of tree-branch-shaped pallets, thereby achieving the purpose of freely adjusting the height of the heat source.

[0071] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
