Description

Technical Field

[0001] This utility model relates to the field of soil evapotranspiration technology, and in particular to a novel soil evapotranspiration meter. Background Technology

[0002] Soil lysimeters are important tools for studying soil moisture transport, solute migration, and water absorption patterns of plant roots. They are widely used in agriculture, hydrogeology, and ecological environment. Traditional lysimeters mainly simulate the seepage process of soil under natural conditions to collect seepage water for analysis of water quality and quantity data, providing a scientific basis for soil moisture management and pollutant migration research. With the increasing demand for precision agriculture and environmental monitoring, higher requirements are placed on the sampling efficiency, ease of operation, and data accuracy of lysimeters. However, existing equipment has limitations in sampling methods and cleaning functions, making it difficult to meet the needs of efficient and accurate detection. Therefore, it is of great significance to develop a new type of soil lysimeter that combines rapid sampling, convenient disassembly, and automated cleaning functions.

[0003] Existing soil lysimeters typically consist of a percolation cylinder, a water collection device, and a support structure. Their technical principle is based on the water infiltration process under gravity. The percolation cylinder is filled with the soil to be tested, and the water infiltrates from top to bottom, eventually entering the water collection device through the bottom filter plate. The water collection device is mostly designed to be fixed.

[0004] Existing soil lysimeters mostly use fixed installation for their water collection devices, which require on-site disassembly and waiting for the leakage to complete during sampling. This results in poor timeliness of water sample acquisition, especially during long-term continuous monitoring. If the leakage water is not collected in time, the water will be lost due to evaporation or secondary infiltration, causing deviations in water volume measurement. At the same time, delayed sampling can lead to changes in solute concentration, such as nutrient dissolution or pollutant degradation, affecting the accuracy of water quality test results. Therefore, a new type of soil lysimeter is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel soil lysimeter, which aims to improve the problem in the prior art where delayed sampling can lead to changes in solute concentration, such as nutrient dissolution or pollutant degradation, affecting the accuracy of water quality test results.

A spring is sleeved on the outer wall of the pressing column, one end of the spring is fixedly connected to the bottom of the fixed disc, and the other end of the spring is fixedly connected to the top of the sliding disc.

[0014] The scraping assembly includes a circular scraper, which is slidably connected to the inner wall of the dialysis unit.

[0015] As a further description of the above technical solution:

[0024] 1. In this utility model, the locking ball of the water collection frame is engaged with the seepage plate by the pin column of the water collection frame, so as to realize the quick installation of the water collection frame; then, the trapezoidal column is raised by the pressing column, so that the locking ball is disengaged, and the water collection frame can be easily disassembled. This allows the water collection frame to be separated from the lyoinfiltration meter body, so as to detect the amount and quality of the seeping water in time. This achieves the effect of obtaining water samples without waiting on site, solves the problem of data deviation caused by untimely sampling in traditional methods, and improves the accuracy and convenience of water quality detection.

[0025] 2. In this utility model, the connecting plate is moved by the electric telescopic rod, and then the sliding rod and the linkage plate are lowered by the connecting plate, which in turn drives the circular scraper to slide along the limiting rod on the inner wall of the lyoinfiltrator body to remove the soil on the inner wall. This achieves the effect of quickly cleaning the inner wall when replacing the soil, and solves the problem of residual soil affecting the detection accuracy. At the same time, it is used in conjunction with the weighing instrument to achieve automatic weighing, which improves the automation level of equipment use and the reliability of detection data.

[0034] Reference Figure 1 - Figure 5 This utility model provides an embodiment of a novel soil lysimeter, comprising a lysimeter body 1 for containing undisturbed soil and simulating a natural evaporation and infiltration environment. A water collection frame 2 is provided on its top for collecting infiltrated water samples to achieve automatic sampling, avoiding water quality changes caused by human intervention. An infiltration plate 4 is fixedly connected inside the lysimeter body 1, serving the dual purpose of supporting soil samples and filtering infiltrated water. A pin column 5 is fixedly connected inside the water collection frame 2 for quick installation and disassembly, facilitating timely water sample collection for water quality and quantity testing. A load-bearing frame 18 is slidably connected inside the lysimeter body 1 to support the soil and maintain weighing stability. A weighing instrument 19 is provided at the bottom of the load-bearing frame 18 to automatically record soil weight changes twice daily, significantly reducing the need for human intervention. The weighing instrument 19 is fixedly connected to the top of the infiltration plate 4 at its bottom. A locking component is provided inside the pin column 5 for the stable fixing and convenient separation of the water collection frame 2.

[0035] The locking assembly includes a locking ball 10, which is slidably connected inside the pin post 5. It locks the water collection frame 2 by engaging with the inner wall of the permeation plate 4. A fixed plate 9 is fixedly connected inside the pin post 5, providing rigid support for the unlocking mechanism. A press-to-unlock assembly is installed inside the fixed plate 9 for quickly releasing the locking state. A scraping assembly is installed on the inner wall of the lysimeter body 1 to automatically remove residual soil to maintain detection accuracy. The press-to-unlock assembly includes a pressing column 7 and a trapezoidal column 11. The pressing column 7 is slidably connected inside the fixed plate 9. The pressing column 11 transmits operating pressure. The bottom of the trapezoidal column 11 is fixedly connected to the top of the pressing column 7, and its side wall is in contact with the outer wall of the locking ball 10. The inclined structure pushes the locking ball 10 out of the locking position. The outer wall of the pressing column 7 is fixedly connected to the sliding plate 6, which limits the pressing stroke and ensures smooth movement. The sliding plate 6 is slidably connected to the inner wall of the pin column 5 to form a guiding constraint. The outer wall of the pressing column 7 is fitted with a spring 8, one end of which is fixed to the bottom of the fixed plate 9 and the other end is fixed to the top of the sliding plate 6, providing automatic reset elasticity to maintain the normal locked state.

[0036] Reference Figure 1 - Figure 5The scraping assembly includes a circular scraper 17, which slides tightly against the inner wall of the lysimeter body 1 to thoroughly remove residual soil and ensure the accuracy of subsequent testing. A limiting rod 16 is fixedly connected to the inner wall of the lysimeter body 1, providing a rigid guide rail to prevent the circular scraper 17 from deviating during movement. The circular scraper 17 is slidably connected to the outer wall of the limiting rod 16 to ensure stable vertical scraping. A linkage plate 15 is fixedly connected inside the circular scraper 17 to evenly transmit driving force to the circular scraper 17. A sliding rod 14 is fixedly connected to the top of the linkage plate 15 as the core of power transmission. The core component, the evaporator body 1, has a support plate 3 fixedly connected to its top, providing a stable mounting base for the electric mechanism. The sliding rod 14 is slidably connected inside the support plate 3 to guide vertical movement. The electric telescopic rod 12 is fixedly connected inside the support plate 3, which can control the lifting stroke of the scraper as needed. The output end of the electric telescopic rod 12 is fixedly connected to a connecting plate 13 for centralized transmission of driving force. The inner wall of the connecting plate 13 is fixedly connected to the outer wall of the sliding rod 14, directly converting the linear motion of the electric telescopic rod 12 into the up and down displacement of the sliding rod 14, ultimately driving the circular scraper 17 to complete the automated cleaning operation.

[0037] Working principle: When installing the water collection frame 2, the water collection frame 2 drives the pin 5 to insert into the permeation plate 4. The retaining ball 10 inside the pin 5 engages with the inner wall of the permeation plate 4 under its own weight, thus fixing the water collection frame 2. When it is necessary to disassemble the water collection frame 2, pressing the pressing column 7 drives the sliding plate 6 to compress the spring 8. At the same time, the pressing column 7 drives the trapezoidal column 11 to rise. The side wall of the trapezoidal column 11 pushes the retaining ball 10 to disengage from the permeation plate 4, and the water collection frame 2 can be removed for water volume and water quality testing. During soil evaporation monitoring, the load-bearing frame 18... The original soil is transferred to the weighing instrument 19 at the bottom by its own weight. The weighing instrument 19 can automatically record the weight change before and after rainfall. At the same time, the soil weight in the morning and evening can also be recorded. When the soil needs to be replaced, the electric telescopic rod 12 on the support plate 3 is activated to drive the connecting plate 13 to move. The connecting plate 13 drives the sliding rod 14 to slide along the support plate 3. The sliding rod 14 drives the linkage plate 15 and the circular scraper 17 to slide down the inner wall of the lysimeter body 1 along the limiting rod 16. The circular scraper 17 scrapes off the residual soil attached to the inner wall to ensure the accuracy of the next test.
