Soil and Water Loss Process Solution - Kyushu Space asks you to answer - solve the ecological environment
The JZ-HE18 automatic soil erosion observation instrument is designed for monitoring soil erosion under various field conditions. It can be used in both fixed standard runoff plots and dynamic field environments, operating unattended throughout the year. The device consists of six main components: a runoff collection system, a runoff measurement unit, a runoff and sediment mixing mechanism, a sediment sampling segmentation device, a data recording system, and a rain protection cover. Its core functions focus on measuring runoff and collecting mixed sediment samples, allowing direct and accurate measurement of runoff areas under different management practices, slope conditions, and land use scenarios.
This equipment is especially useful for soil and water loss monitoring in erosion control zones and engineering development projects. It records key parameters such as the start time of runoff, section runoff, and sedimentation levels. It can track individual erosion events or accumulate total amounts, and it supports continuous monitoring over an entire year. The device offers flexible configurations based on catchment size and runoff volume. It is lightweight, easy to install, and requires no external power supply. It features automatic recording, segmented sampling, and data storage with a record box that allows data transfer via computer.
Compared to traditional standard runoff plots, the JZ-HE18 provides higher utilization efficiency, realistic results under natural conditions, and real-time process observation. It also reduces post-processing efforts and improves sediment measurement accuracy, achieving 95.6% accuracy in sediment content tests between 0.1% and 10%. The device is versatile, suitable for various field observations, and supports automatic operation with data download capabilities.
In comparison to existing mobile runoff observation devices, the JZ-HE18 can handle large flow rates, is easy to install, and operates without additional power. It ensures high precision, collects only one sample level, minimizes failures, and offers cost-effective performance.
The product includes a triangular runoff collector, a dumper and runoff transfer tube, an electromagnetic sensor, and a data logger with memory. It also features a sediment mixer and sample segmentation collector, along with a USB interface and user-friendly software for data retrieval and reporting.
The JZ-HE18 series comes in multiple models tailored for different applications:
- **JZ-HE18**: Ideal for small to medium catchments, with a maximum runoff rate of 100 kg/min.
- **JZ-HE18I**: Designed for large catchments, capable of handling up to 750 kg/min.
- **JZ-HE18II**: Suitable for detailed soil erosion research, focusing on sediment transport processes.
Key technical specifications include a minimum runoff measurement of 0.1–10 kg, a maximum of 0.32–320 kg/min, a sediment content range of 0–100 kg/m³, and a working life of over 10 years. The device is made of corrosion-resistant stainless steel, ensuring durability in harsh environments.
The JZ-HE18 series has been successfully deployed by institutions such as the Institute of Botany, Chinese Academy of Agricultural Sciences, Northwest A&F University, and Heilongjiang Land Reclamation Projects. It offers users the ability to set data collection intervals, adjust clock settings, and view real-time data through a graphical display. With its low cost, ease of use, and high accuracy, the JZ-HE18 series is a reliable solution for soil and water conservation monitoring.
