Description

Technical Field

[0001] This utility model relates to the field of soil evapotranspiration measurement technology, and more specifically, to a simple device for assisting in the measurement of evapotranspiration. Background Technology

[0002] Soil evapotranspiration measurement refers to the process of quantitatively measuring the amount of water lost from the soil to the atmosphere through evaporation and plant transpiration using scientific methods and instruments. It reflects a crucial link in the water cycle within the soil-plant-atmosphere system and is a key parameter for studying regional hydrological processes, assessing water resource utilization efficiency, and analyzing ecosystem water balance. Soil evapotranspiration measurement can typically be achieved through direct measurement methods (such as the water balance method and eddy covariance method) or indirect estimation methods (such as the Penman-Monteith formula based on meteorological data). The results are of great significance for fields such as agricultural irrigation management, water resource planning, and climate change research.

[0003] A search revealed an existing patent (publication number: CN214121319U) that discloses a double-layer protection device for a sensor, comprising an outer sleeve and an inner sleeve. The outer sleeve includes a sealing section, a connecting section, and a raised section from bottom to top, with the inner sleeve fixed inside the outer sleeve. The inner sleeve includes a first tube body, a second tube body, and a third tube body from bottom to top. The sidewalls and bottom wall of the sealing section are sealed and the entire section is positioned below the mud surface of the paddy field. The connecting section has a connecting hole, the raised section is above the highest water level, the tube wall and bottom wall of the first tube body are sealed, and the second tube body has micropores connected to the connecting hole. The beneficial effects of this invention are: through the double-layer filtration of the outer and inner sleeves, the outer sleeve effectively prevents weeds and coarse silt from entering, while the inner sleeve performs fine filtration, preventing even finer silt particles from entering, thus avoiding the impact of fine silt on the measurement accuracy of the water depth sensor.

[0004] However, the insect-proof netting of this device has significant drawbacks in practical applications. While it effectively blocks small insects and impurities, its small pore size significantly hinders the diffusion of water vapor. In environments with high humidity or large temperature differences, water vapor easily condenses into droplets on the inside of the netting and drips back into the measurement space or soil sample. This phenomenon increases soil moisture, interferes with the true state of soil moisture, and consequently causes serious deviations in the calculation results of evapotranspiration or soil moisture dynamics, reducing the measurement accuracy and reliability of the device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a simple device for assisting in the measurement of evaporation, so as to solve the problem that insect nets will intercept water vapor, causing water droplets to fall back into the sample and interfere with the measurement accuracy.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a simple device for assisting in the measurement of evaporation, comprising: an evaporation measurement fixing cylinder; an insect-proof and backflow-proof interception component mounted on the evaporation measurement fixing cylinder, the insect-proof and backflow-proof interception component being used to prevent flying insects from entering and to prevent water after evaporation from falling back, the insect-proof and backflow-proof interception component comprising: an insect-proof part mounted on the top of the evaporation measurement fixing cylinder, the insect-proof part having an evaporation water source guide part mounted inside, the evaporation water source guide part being used to guide water source; and a water receiving trough detachably installed inside the evaporation measurement fixing cylinder; a buried fixing component mounted on the bottom of the evaporation measurement fixing cylinder, the buried fixing component being used to collect experimental soil and fix the device; a filter and anti-pollution component mounted inside the evaporation measurement fixing cylinder, the filter and anti-pollution component being used to prevent microorganisms from entering; and a soil sample detection component mounted inside the buried fixing component, the soil sample detection component being used to monitor the evaporation amount.

[0009] Preferably, the buried fixing assembly includes: a bottom sleeve assembled at the bottom of the evaporation measuring fixing cylinder, a support plate fixedly installed on the outer surface of the bottom sleeve, multiple sets of support plates being provided, the multiple sets of support plates being equidistantly arranged on the outer surface of the bottom sleeve, a threaded sleeve fixedly installed on the top of the bottom sleeve, and the bottom sleeve being threadedly connected to the evaporation measuring fixing cylinder through the threaded sleeve.

[0010] Preferably, the filter and anti-pollution component includes: a hydrophobic and breathable membrane fixedly installed inside the evaporation measuring cylinder, wherein an ultrafine stainless steel wire mesh is fixedly installed at the bottom of the hydrophobic and breathable membrane.

[0011] Preferably, the soil sample testing assembly includes: a weight detector fixedly installed inside the bottom sleeve, and a sample placement box detachably installed on the top of the weight detector.

[0013] Preferably, the weight detector is connected to an existing receiver, which is used to detect the weight of the soil sample in real time.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention inserts the bottom sleeve of the buried fixing component into the soil, and uses support plates to ensure stable fixation of the device. Next, the sample placement box in the soil sample testing component is filled with the soil sample to be tested and placed on the weight detector, which monitors the weight change of the soil sample in real time via a receiver. The evaporation measurement fixing cylinder is equipped with a filter and anti-contamination component. A hydrophobic and breathable membrane allows water vapor to pass through, while an ultra-fine stainless steel wire mesh effectively intercepts microorganisms and other impurities, preventing them from entering the measurement space. This solves the problem of water droplets falling back into the sample and interfering with measurement accuracy caused by traditional insect-proofing methods that intercept water vapor. At the top of the device, the insect-proof and anti-backflow interception component's insect-proof net prevents flying insects from entering, and the guiding drip ring directs any condensing water droplets to the water collection tank, preventing them from falling back into the sample. Through the coordinated work of all components, the entire device not only effectively prevents interference from microorganisms and flying insects but also ensures the normal diffusion of water vapor, improving the accuracy and reliability of evapotranspiration measurement.
