Description

Technical Field

[0001] This utility model belongs to the field of climate observation technology, and more specifically, it relates to a farmland climate observation station. Background Technology

[0002] Current agricultural production increasingly utilizes internet technologies such as smart connectivity, the Internet of Things, and big data, effectively mitigating the impact of natural disasters and freeing farmers from the constraints of soil-based cultivation. This makes agricultural operations more ecological, intelligent, urbanized, and flexible. Nevertheless, greenhouse crops with artificially regulated microclimates constitute only a small portion; the vast majority of crops are still affected by the natural environment. Therefore, it is crucial to conduct timely weather forecasting and proactive agricultural meteorological disaster prevention and mitigation work.

[0003] In existing technologies, farmland climate observation stations are often equipped with temperature and humidity sensors. Multiple sensors are spaced out vertically to eliminate random errors from a single height by using multi-point data. However, to match the growth needs of crops at different heights, avoid interference from localized high humidity caused by soil evaporation or irrigation, or reduce sensor temperature measurement deviations due to direct sunlight, the height of the temperature and humidity sensors needs to be adjusted. Since each temperature and humidity sensor is individually fixed to the farmland climate observation station with screws, adjusting the height of multiple sensors requires disassembling each screw individually, a very tedious process.

[0028] Current agricultural production increasingly utilizes internet technologies such as smart connectivity, the Internet of Things, and big data, effectively mitigating the impact of natural disasters and freeing farmers from the constraints of soil-based cultivation. This makes agricultural operations more ecological, intelligent, urbanized, and flexible. Nevertheless, greenhouse crops with artificially regulated microclimates constitute only a small portion; the vast majority of crops are still affected by the natural environment. Therefore, it is crucial to conduct timely weather forecasting and proactive agricultural meteorological disaster prevention and mitigation work.

[0029] In existing technologies, farmland climate observation stations are often equipped with temperature and humidity sensors. Multiple sensors are spaced out vertically to eliminate random errors from a single height by using multi-point data. However, to match the growth needs of crops at different heights, avoid interference from localized high humidity caused by soil evaporation or irrigation, or reduce sensor temperature measurement deviations due to direct sunlight, the height of the temperature and humidity sensors needs to be adjusted. Since each temperature and humidity sensor is individually fixed to the farmland climate observation station with screws, adjusting the height of multiple sensors requires disassembling each screw individually, a very tedious process.

[0030] Please see Figures 1 to 7The following describes the farmland climate observation station provided by this utility model. The farmland climate observation station includes a main pole 10, an adjusting rod 30, a screw 33, and several temperature and humidity sensors 22. The lower part of the main pole 10 has a horizontally extending first support 11. A solar panel 20 and a data collection box 21 are mounted on the main pole 10, and the solar panel 20 is electrically connected to the data collection box 21. The adjusting rod 30 is located below the first support 11 and extends downwards. An upwardly extending strip 31, located on one side of the first support 11, is connected to the upper side wall of the adjusting rod 30. An elongated hole 32 extending upwards to the upper edge of the strip 31 is provided through the strip 31. The screw 33 is connected to the side wall of the first support 11 and passes through the elongated hole 32. An adjusting nut 34 is threaded onto the screw 33 to lock the vertical position of the strip 31. Several temperature and humidity sensors 22 are spaced apart on the adjusting rod 30 in a vertical direction, and the temperature and humidity sensors 22 are electrically connected to the data collection box 21.

[0031] Furthermore, the collection box 21 is equipped with a storage battery.

[0032] Furthermore, there are two slats 31, which are located on both sides of the first bracket 11.

[0033] Furthermore, the first bracket 11 is connected to the main rod 10 by U-bolts.

[0034] This application provides a farmland climate observation station. In practical use, the combination of the adjusting rod 30, slats 31, elongated hole 32, screw 33, and adjusting nut 34 enables convenient and precise vertical height adjustment of the temperature and humidity sensor 22. Different crops (such as dwarf and tall crops), different growth stages (such as seedling and heading stages), and different monitoring needs (such as canopy temperature and humidity, ventilation in the middle of the crop, and near-ground microclimate) require the sensor to be located at a specific height. This structure allows for rapid on-site adjustment of the sensor array to the optimal position, significantly improving the representativeness and accuracy of the data.

[0035] Multiple temperature and humidity sensors 22 are arranged vertically and horizontally along the adjustment rod 30, enabling simultaneous collection of temperature and humidity data at different vertical levels. This reveals the temperature and humidity gradients in the near-surface atmosphere of farmland (such as the formation of inversion layers and the vertical distribution of water vapor lost through evaporation), which is crucial for studying crop transpiration, disease occurrence (such as leaf dew), and frost warning.

[0036] The main pole 10 serves as the core support, integrating solar panels 20 (power supply) and a data acquisition box 21 (data processing and storage). The first support bracket 11 provides horizontal support, enhancing overall wind resistance. All sensors are electrically connected to the data acquisition box 21, achieving energy self-sufficiency and centralized data acquisition and preliminary processing, simplifying wiring, and improving system reliability and ease of deployment.

[0037] When the height of the temperature and humidity sensor 22 needs to be adjusted, simply loosen the adjusting nut 34 and move the adjusting rod 30 up and down. After adjustment, tighten the adjusting nut 34. There is no need to disassemble each temperature and humidity sensor 22 one by one, which realizes the synchronous and rapid adjustment of the height of multiple temperature and humidity sensors 22.

[0038] Compared with the prior art, the farmland climate observation station provided in this embodiment only requires loosening the adjusting nut 34 and moving the adjusting rod 30 up and down when the height of the temperature and humidity sensor 22 needs to be adjusted. After the adjustment is completed, the adjusting nut 34 is tightened. There is no need to disassemble each temperature and humidity sensor 22 one by one, which realizes the synchronous and rapid adjustment of the height of multiple temperature and humidity sensors 22.

[0039] In one possible implementation, the aforementioned adjusting rod 30 adopts, as shown in... Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2 The upper end of the adjusting rod 30 is connected to a guide rod 35 that extends upward through the first bracket 11, and the guide rod 35 slides in cooperation with the first bracket 11.

[0040] Specifically, the guide rod 35 extends upward through the first bracket 11 and slides with it, providing additional vertical guidance and constraint for the adjusting rod 30. When adjusting the height or under wind force, it can effectively prevent the adjusting rod 30 from laterally swinging, shaking, or rotating, ensuring that the sensor array always remains within the set vertical plane, greatly improving the stability and positional accuracy of the measurement.

[0041] In strong winds, the cooperation between the guide rod 35 and the bracket can significantly suppress the vibration and offset of the adjusting rod 30, ensuring that the sensor can still acquire reliable data under adverse weather conditions.

[0042] In one possible implementation, the aforementioned main rod 10 adopts the following... Figure 1 , Figure 3 and Figure 6 The structure shown is described in the following document. Figure 1 , Figure 3 and Figure 6 The lower end of the main rod 10 is provided with a base 12 for burying in the soil. A first proportional plate 40 extending in the vertical direction is provided on one side of the base 12. A soil moisture sensor 23 is provided on the first proportional plate 40. A first mounting rod 41 that horizontally penetrates the first proportional plate 40 is provided on the top of the base 12.

[0043] Specifically, the soil moisture sensor 23 and the data acquisition box 21 are electrically connected. Through the first proportional plate 40 and the soil moisture sensor 23, continuous, in-situ monitoring of the key soil parameter—moisture content—is achieved. This is crucial for precise irrigation decisions, drought and flood early warning, and research on crop water stress.

[0044] The base 12 provides a foundation for anchoring. The first mounting rod 41 extends horizontally through the first proportioning plate 40, securing the proportioning plate firmly but detachably to the base 12. This design facilitates the installation, calibration, replacement, or maintenance of the soil moisture sensor 23, while ensuring that it is not easily displaced or damaged under tillage or natural conditions.

[0045] Furthermore, several soil moisture sensors 23 are spaced apart along the vertical direction.

[0046] The equipment can be installed one by one according to the standardized depth or proportion (such as 10cm, 20cm, 40cm, etc., for the main distribution layers of crop roots) on the first scale plate 40. This ensures that the data is comparable and can reflect the moisture status of different soil layers.

[0047] Furthermore, the soil moisture sensor 23 is connected to the first proportional plate 40 via U-bolts.

[0048] In some embodiments, see Figure 1 , Figure 3 and Figure 6 The base 12 has a second proportional plate 50 extending in the vertical direction on one side, and a ground temperature sensor 24 is provided on the second proportional plate 50. The base 12 has a second mounting rod 51 that horizontally penetrates the second proportional plate 50 on the top.

[0049] Specifically, continuous monitoring of soil temperature at different depths is achieved through a second proportional plate 50 and a ground temperature sensor 24. Soil temperature directly affects seed germination, root growth, microbial activity, and nutrient decomposition rate.

[0050] Furthermore, several ground temperature sensors 24 are spaced apart along the vertical direction.

[0051] The second scale plate 50 also supports the installation of ground temperature sensors 24 at multiple standardized depths to obtain vertical profile data of soil temperature. This is of great value for studying permafrost thawing, the impact of ground temperature on root systems, and the conditions for the occurrence of specific pests and diseases (such as certain pathogens preferring specific soil temperatures).

[0052] In one possible implementation, the aforementioned main rod 10 adopts the following... Figure 1 , Figure 4 , Figure 6 and Figure 7 The structure shown is described in the following document. Figure 1 , Figure 4 , Figure 6 and Figure 7The upper part of the main pole 10 is provided with a lightning rod 25. The lightning rod 25 is set on the main pole 10 by a clamping assembly 60. The clamping assembly 60 includes two U-shaped buckles 61 that are arranged opposite to each other and hug the outer periphery of the main pole 10. The U-shaped buckles 61 extend horizontally and both ends are connected by fasteners 62. The lightning rod 25 is set between the two U-shaped buckles 61.

[0053] Specifically, in open farmland areas, observation stations (especially the metal main pole 10 and the towering sensors) are high-risk points for lightning strikes. Installing lightning rods 25 and safely discharging lightning current to the ground through a grounding system is an absolutely necessary measure to protect the expensive electronic equipment (data acquisition box 21, sensors) and personnel within the station.

[0054] Two U-shaped buckles 61 are used to hold the main pole 10 together, and the two ends are connected by fasteners 62 (such as bolts), which provides strong clamping force to firmly fix the lightning rod 25 to the main pole 10, making installation and disassembly very convenient.

[0055] The U-shaped buckle 61's clamping mechanism adapts to main rods 10 of different diameters (within a certain range), offering strong versatility. The clamping assembly 60 itself has a simple and reliable structure.

[0056] Furthermore, two clamping components 60 are provided at intervals along the vertical direction.

[0057] Furthermore, the fastener 62 includes a bolt passing through the two U-shaped fasteners 61 and a nut threadedly connected to the bolt.

[0058] In some embodiments, see Figure 1 , Figure 4 , Figure 6 and Figure 7 The U-shaped buckle 61 has an outwardly arc-shaped convex clamping part 63, and the main rod 10 is located between the two clamping parts 63. The adjacent sides of the two U-shaped buckles 61 are provided with receiving grooves for accommodating the lightning rod 25.

[0059] Specifically, the outwardly curved convex clamping part 63 of the U-shaped buckle 61 allows it to better fit the cylindrical curved surface of the main rod 10 when tightened, increasing the contact area, significantly improving the stability and firmness of the clamping, and preventing the lightning rod 25 from loosening under strong winds or vibrations.

[0060] Receiving grooves are provided on the adjacent sides of the U-shaped buckle 61 to provide a precise installation position and radial constraint for the lightning rod 25, preventing it from moving laterally or rotating.

[0061] In some embodiments, see Figure 1 , Figure 4 , Figure 6 and Figure 7 The receiving groove is provided with an arc-shaped plate 64 that extends in the vertical direction and hugs the outer periphery of the lightning rod 25.

[0062] Specifically, an arc-shaped plate 64 extending axially along the lightning rod 25 is added within the receiving groove, circumferentially enclosing the lightning rod 25 throughout its entire clamped section (or critical section). This virtually eliminates any possible micro-movements, swaying, or vibrations of the lightning rod 25 within the groove, providing optimal fixation. This is crucial for applications subject to strong winds, mechanical vibrations, or lightning strikes.

[0063] In one possible implementation, the aforementioned solar panel 20 employs, as shown in... Figure 1 and Figure 5 The structure shown is described in the following document. Figure 1 and Figure 5 The solar panel 20 is mounted on the main pole 10 via the second bracket 13. The second bracket 13 is provided with a main clamp 70 and a secondary clamp 71 that hug the outer periphery of the main pole 10. The main clamp 70 and the secondary clamp 71 are connected by a connector 72.

[0064] Specifically, the second bracket 13 (supporting the solar panel 20) is installed by fixing the main clamp 70 and the auxiliary clamp 71 to the main pole 10 through the connector 72, providing an extremely stable and load-bearing installation platform. This is crucial for the large area and wind-exposed area of ​​the solar panel 20 to resist strong winds, ensuring the continuity of the core energy supply of the observation station.

[0065] The clamp structure also avoids welding or drilling on the main rod 10, maintaining the integrity and strength of the main rod 10.

[0066] Furthermore, the connector 72 includes a bolt passing through the main clamp 70 and the secondary clamp 71, and a nut threadedly connected to the bolt.

[0067] In some embodiments, see Figure 1 and Figure 5 Two secondary clamps 71 are provided at intervals along the vertical direction.

[0068] Specifically, two secondary clamps 71 are installed at intervals along the main pole 10, increasing the number of fixing points between the second bracket 13 and the main pole 10 from one to two (two secondary clamps 71). This greatly enhances the rigidity, stability, and wind and torsional resistance of the entire solar panel 20 support structure.

[0069] Multi-point support effectively disperses the weight and wind load of the solar panel 20, preventing the second support 13 (especially the longer support) from bending or sagging due to stress, and ensuring that the solar panel 20 maintains the best posture for a long time.

[0070] In one possible implementation, the aforementioned main rod 10 adopts the following... Figure 1 and Figure 6 The structure shown is described in the following document. Figure 1 and Figure 6 The top of the main pole 10 is equipped with a wind speed detector 26 and a wind direction detector 27. The upper part of the main pole 10 is equipped with a total radiation sensor 28 and a camera 29. The first bracket 11 is equipped with a rainfall detector 80.

[0071] Specifically, the wind speed detector 26, wind direction detector 27, total radiation sensor 28, camera 29, and rainfall detector 80 are all electrically connected to the data acquisition box 21.

[0072] Top: Wind speed detector 26 and wind direction detector 27 monitor the wind field conditions in farmland, which affect evaporation, pollination, pest and disease transmission, and pesticide application effectiveness.

[0073] Top: Total Radiation Sensor 28 directly measures total solar radiation (the main source of photosynthetically active radiation), which is a core driving factor for crop growth and evapotranspiration estimation.

[0074] The Rainfall Detector 80 accurately records precipitation events and magnitudes for use in water balance calculations and drought / flood assessments.

[0075] Camera 29: Provides real-time visualization of crop growth status, coverage, signs of pests and diseases, field operation verification, etc., and is a powerful supplement to meteorological data.

[0076] Furthermore, a horizontally extending crossbar is connected to the top of the main pole 10, with an anemometer 26 and a wind direction meter 27 respectively installed at both ends of the crossbar.

[0077] Furthermore, the upper part of the main rod 10 is provided with a horizontally extending third bracket, which is connected to the main rod 10 by U-bolts. The total radiation sensor 28 and the camera 29 are mounted on the third bracket.

[0078] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
