Description

Technical Field

[0001] This invention relates to the field of wheat planting technology, and in particular to a wheat late spring frost disaster simulation and monitoring device. Background Technology

[0002] A late spring frost is a very serious agricultural meteorological disaster, referring to a weather phenomenon in spring when frequent attacks by strong cold air masses cause a rapid drop in temperature, resulting in sustained frost damage to crops over a wide area. Generally, mild to moderate late spring frosts can lead to a 10%-30% reduction in wheat yield, while severe late spring frosts can cause yield reductions of over 50% and deterioration in grain quality. Therefore, there is an urgent need to study the disaster-causing mechanism of late spring frosts in wheat production, thereby providing theoretical support for the development of disaster prevention and mitigation technologies for wheat production.

[0003] During the late spring frost disaster, there are two main scenarios: rapid cooling and slow cooling. However, existing wheat late spring frost disaster simulation and monitoring devices have limited functions and are difficult to simulate different cooling scenarios. In addition, their isolation performance is poor and the experimental error is large. Therefore, a wheat late spring frost disaster simulation and monitoring device is proposed.

A U-shaped docking plate 415 is connected to the opening of the tightening plate 414.

[0034] When conducting simulated monitoring of late spring frost in wheat, ditches are dug on both sides of the wheat-planted area to house the monitoring device. Then, the support component 2 is placed in the ditches on both sides of the wheat, and the heat insulation and temperature control component 1 is placed on top of the support component 2 and connected to it. The heat insulation and temperature control component 1 and the support component 2 are distributed along the length of the ditch. After that, the stabilizing mechanism 4 is installed and reinforced to the support component 2. Then, the temperature regulating mechanism 5 and the heat insulation and temperature control component 1 are used to conduct simulated monitoring of late spring frost in wheat.

[0035] Example 2:

[0036] The heat insulation and temperature control component 1 includes a U-shaped heat insulation layer 11. Both sides of the heat insulation layer 11 are fixed with U-shaped pull straps 12 for docking with the support component 2. Both sides of the bottom of the heat insulation layer 11 are fixed with heat-conducting bags 13 distributed along its length direction.

[0037] Both ends of the heat insulation layer 11 are provided with end sealing layers for sealing. The end sealing layers are detachably connected to the heat insulation layer 11 by Velcro or zipper. The bottom outer wall of the heat insulation layer 11 is detachably connected with a reinforcing layer by Velcro or zipper.

[0038] Support component 2 includes a U-shaped support jacking pipe 22. Both ends of the bottom of the support jacking pipe 22 are threaded with vertical rods 21. The bottom of the vertical rods 21 is connected to a bent pipe 23. Both ends of the bottom of the bent pipe 23 are fixed with support pipes 24. Rollers 25 are installed at the bottom of the support pipes 24. A pressing mechanism 3 is set on the adjacent support pipes 24. A connecting mechanism 6 is set on the vertical rods 21.

[0039] The pressing mechanism 3 includes a pressing plate 31 that is slidably sleeved on the support tube 24 of the support assembly 2. A plug rod 32 for fixing the heat insulation and temperature control assembly 1 is fixedly connected to one side of the pressing plate 31. A horizontal plate 33 that is fixedly connected to the support tube 24 of the support assembly 2 is provided at the bottom of the pressing plate 31.

[0040] The temperature control mechanism 5 includes a temperature control tube disposed on one side of the support component 2. A support plate is installed at the bottom of the temperature control tube and fixed to the support tube 24 of the support component 2. A placement groove for placing the temperature control tube is opened at the top of the support plate.

[0041] The connecting mechanism 6 includes a rotating tube 61 that is rotatably sleeved on the outer ring of the vertical rod 21 of the support assembly 2. The outer ring of the rotating tube 61 is fixed with an arc-shaped hook plate 62 for connecting with the heat insulation and temperature control assembly 1. One end of the rotating tube 61 is slidably sleeved with a locking sleeve 63 that is slidably connected to the support assembly 2. One end of the rotating tube 61 that extends into the locking sleeve 63 is fixedly connected with a spring that is fixedly connected to the end of the locking sleeve 63. The cross-section of the inner ring of the locking sleeve 63 is consistent with the cross-section of the outer ring of the rotating tube 61 and both are regular polygonal structures.

[0042] The end of the adjusting shaft 48 away from the movable disk 45 is provided with an inwardly recessed adjusting groove. The cross-section of the adjusting groove is a regular polygonal structure. The side of the movable disk 45 away from the adjusting shaft 48 is fixedly connected to a spring 2 that is fixedly connected to the inner wall of the adjusting disk 41. The clamping plate 47 and the adjacent driven rod 412 are engaged by a tooth and slot method.

[0043] The regulating plate 41 has four sets of retaining tubes 410, and the four sets of retaining tubes 410 are distributed in an X-shape along the axis of the regulating plate 41. At least two sets of stabilizing mechanisms 4 are provided between adjacent support components 2.

[0044] Example 3:

[0045] The support component 2 is equipped with a camera for acquiring images and a sensor for acquiring temperature information. A gas supply pipe is installed on one side of the temperature control tube. The temperature control tube is equipped with a nozzle arranged along its length. A solenoid valve and a nozzle are installed on the nozzle. Heat-conducting fins are arranged sequentially along its length on the outer ring of the temperature control tube.

[0046] During installation, the support components 2 are arranged sequentially along the length of the trench. Then, the heat insulation and temperature control components 1 are placed on top of the support components 2. When the heat insulation and temperature control components 1 are placed on the support components 2, the locking sleeve 63 is first pushed away from the rotating tube 61 so that the locking sleeve 63 is not stuck with the rotating tube 61. Then, the rotating tube 61 is pushed to rotate so that the hook plate 62 on the rotating tube 61 is connected with the pull strap 12 on the heat insulation layer 11.

[0047] Subsequently, the support assembly 2 is reinforced using the stabilizing mechanism 4. During connection, the tightening plate 414 is fitted onto the vertical rod 21 or the support top tube 22 of the support assembly 2. Then, an adjusting tool with a cross-section matching the adjusting groove on the adjusting shaft 48 is inserted into the adjusting hole 42 of the adjusting plate 41. The adjusting tool is then inserted into the adjusting groove of the adjusting shaft 48 and pushed towards one side of the movable plate 45. The adjusting shaft 48 drives the movable plate 45 to move, preventing the clamping plate 47 from engaging with the driven rod 412, thus preventing the driven rod from being engaged. 412 is restricted, and at the same time, the bevel gear 49 on the adjusting shaft 48 abuts and meshes with the bevel gear 2. The adjusting shaft 48 is rotated using an adjusting tool, which then drives the bevel gear 49 to rotate, and then the driven rod 412 rotates. Subsequently, under the action of the thread, the push-pull rod 411 moves along its length direction, thereby adjusting the distance between the two sets of support components 2 and realizing the reinforcement connection operation of the support components 2. After that, the docking plate 415 is connected to the tightening plate 414 by bolts, and the stabilizing mechanism 4 is fixed between the adjacent support components 2.

[0048] At the same time, the pressing mechanism 3 is used to press the heat insulation and temperature control component 1 onto the ditch, so that the heat conduction bag 13 is in full contact with the ditch. The pressing plate 31 is pressed down so that the insertion rod 32 extends into the hole reserved on the tensioning band 14. At the same time, the outer ring of the insertion rod 32 is fixed with a pressure plate for pressing contact.

[0049] During simulation monitoring, a low-temperature liquid medium is introduced into the heat-conducting bag 13 through the feed pipe. This medium increases the overall weight of the bag, ensuring the bottom of the bag is in full contact with the ditch ground, improving the sealing effect. Simultaneously, the reinforcing layer on the outside of the bag isolates the soil from the outside of the insulation layer 11. Furthermore, the metal heat-conducting fins on the bag exchange heat with the space inside the insulation layer 11, slowly cooling the wheat. Simultaneously, a low-temperature medium is supplied from the temperature control pipe, and the heat-conducting fins on the pipe further slowly cool the space inside the insulation layer 11. When rapid cooling is needed, the solenoid valve on the nozzle of the temperature control pipe is opened, and the low-temperature medium is sprayed along the nozzle into the space inside the insulation layer 11, rapidly cooling the wheat. This simulation monitors late spring frosts under different conditions, using sensors and cameras to collect data on the wheat's resistance to late spring frosts, providing data support for wheat late spring frost resistance research.

[0050] This invention adopts a modular design, which facilitates assembly testing, reduces the difficulty of simulation monitoring, improves detection efficiency, and has a stable overall structure, making it easy to conduct simulation tests in outdoor experimental fields. It has strong wind resistance and can effectively isolate the internal and external temperatures of the simulation test, making it easy to simulate the environment of late spring cold snaps. It can simulate the wheat growth environment under rapid cooling and slow cooling environments according to different simulation test requirements, improving the adaptability of simulation monitoring and facilitating the collection of wheat growth data under different conditions.

[0051] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
