Description

Technical Field

[0001] This utility model relates to the field of water environment monitoring technology, specifically to a sediment water quality monitoring device. Background Technology

[0002] Water environment monitoring is a crucial foundation for water resource management and protection, especially in areas such as agricultural irrigation and ecological protection. Accurate monitoring of sediment content and water quality indicators is key to the rational utilization of water resources. In southern Xinjiang, irrigation canals, as vital infrastructure for agricultural irrigation, suffer from high sediment content and significant water quality fluctuations due to their unique geographical environment, making traditional monitoring methods highly limiting.

[0003] Traditional sediment and water quality monitoring relies heavily on manual sampling and laboratory analysis, which presents several problems: First, it lacks timeliness, as manual sampling is time-consuming and struggles to capture dynamic changes in water quality, especially during flood season or peak irrigation periods, where data delays can lead to decision-making errors. Second, it suffers from large errors, as manual operations are affected by factors such as sampling location, time, and method, resulting in poor data repeatability and a high error rate in sediment concentration measurements. Third, it is costly, requiring long-term employment of professionals for field sampling and laboratory analysis, which involves significant investment in manpower and equipment. Fourth, it has poor environmental adaptability, as the arid climate and large diurnal temperature variations in southern Xinjiang pose challenges to manual sampling, including high temperatures and dust storms, leading to low safety.

[0004] Existing automated monitoring devices also have significant shortcomings: some devices can only monitor water quality indicators and cannot simultaneously measure sediment concentration, requiring additional sampling equipment; some sediment monitoring devices are fixed in installation, making it difficult to adapt to changes in channel water levels, and the fixed sampling depth leads to insufficient data representativeness; some devices have unreasonable design of filtration and drying components, resulting in incomplete sediment separation or low drying efficiency, affecting the accuracy of concentration calculations. In addition, most devices rely on external power supplies, making them difficult to deploy in remote canal areas of southern Xinjiang, and they lack protection against extreme weather conditions, resulting in a high equipment failure rate.

[0005] Therefore, developing an automated device that integrates automatic sampling, sediment separation, concentration calculation, and multi-parameter water quality monitoring, and is adapted to the canal environment in southern Xinjiang, has become the key to improving the efficiency and accuracy of water environment monitoring. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned problems and provide a sediment and water quality monitoring device. To achieve the above objective, this invention adopts the following technical solution:

[0007] A sediment and water quality monitoring device includes a main body, which comprises an air compressor, a fluid acid-base detector, and a robotic arm. The fluid acid-base detector is installed inside the air compressor, which is located beside a river. The robotic arm is located on one side of the air compressor, with its front end extending into the river. A water pump assembly is mounted on the robotic arm, and a water quality monitoring sensor is mounted at the front end of the robotic arm. The fluid acid-base detector contains a filter and a drying assembly. The water pump assembly draws water, which passes through the filter and drying assembly to measure the sediment concentration.

[0008] As an improvement, the robotic arm includes a first hinge assembly, a second hinge assembly, and a fixed base. The fixed base is fixed to the side of the pneumatic compressor, the second hinge assembly is disposed on the fixed base, the first hinge assembly and the second hinge assembly are hinged together, and a pull rod is provided between the second hinge assembly and the fixed base.

[0009] As an improvement, the air compressor includes a frame, a protective cover, and a solar power generation component. The frame is fixed to the side of the river, the protective cover is installed on the top of the frame, the solar power generation component is installed on the top of the protective cover, and the fluid acid-base detector is installed inside the protective cover.

[0010] As an improvement, the main body of the device is also equipped with a control system, which is electrically connected to a water quality monitoring sensor, a fluid acid-base detector, and a pneumatic compressor.

[0011] The advantages of this utility model are:

[0012] 1. This utility model significantly improves monitoring efficiency and accuracy: it achieves fully automated sampling and analysis, capturing dynamic changes in water quality and sediment concentration in real time. Through fixed-volume water sampling, precise filtration, and drying, the error rate of sediment concentration measurement is reduced. The water quality monitoring sensor simultaneously measures more than 10 indicators, and the comprehensiveness and consistency of data acquisition are superior to traditional segmented detection methods.

[0013] 2. This utility model exhibits strong environmental adaptability and is suitable for the special scenarios in southern Xinjiang. The protective cover and wind and sand protection design enable the device to operate stably in harsh environments such as high temperatures and sandstorms, reducing the failure rate. The solar power generation components solve the power supply problem in remote canal areas, and the device can continue to operate on the basis of energy storage batteries during continuous rainy weather, ensuring uninterrupted monitoring. The multi-dimensional adjustment function of the robotic arm can adapt to changes in canal water level, expand the sampling depth range, and make the data more representative.

[0014] 3. This invention reduces labor costs and improves operational safety: it completely replaces manual field sampling and laboratory analysis, reducing manpower input and especially avoiding the risks of manual operation in the high-temperature and strong sunlight environment of southern Xinjiang. Remote control and data transmission functions allow managers to complete monitoring tasks without going to the site, significantly improving work efficiency. Attached Figure Description

[0027] Example 1

[0028] This embodiment discloses a sediment and water quality monitoring device.

[0029] like Figures 1 to 4 As shown, this embodiment includes a main body of the device, which consists of a pneumatic compressor 1, a fluid acid-base detector 2, a robotic arm 3, and a control system. The robotic arm 3 automatically collects water, filters and dries it, and then measures the sediment concentration. At the same time, sensors are used to monitor multiple water quality indicators simultaneously, realizing the full automation of the monitoring process.

[0030] Core structure and functions

[0031] The main frame of the device is based on the air compressor 1, which is fixed to the hardened ground beside the river channel 4 or canal, providing stable support for the entire device. The air compressor 1 includes a frame 10, on which a protective cover 11 is installed. The cover is made of wind and sand resistant material and forms an enclosed space to protect the internal equipment from the harsh climate of southern Xinjiang. A solar power generation component 12, including solar panels and energy storage batteries, is installed on the top of the protective cover 11 to provide clean energy for the device and adapt to scenarios in remote areas without external power supply.

[0032] Robotic arm 3: Located on one side of the pneumatic compressor 1, it includes a fixed base 8, a first hinge assembly 6, a second hinge assembly 7, and a pull rod 9. The fixed base 8 is fixed to the side of the pneumatic compressor 1 and connected to the ground via expansion bolts. The second hinge assembly 7 is mounted on the fixed base 8 and hinged to the first hinge assembly 6, enabling multi-dimensional rotation and extension, ensuring the front end can reach different depths and positions within the channel for sampling. The pull rod 9 connects the second hinge assembly 7 to the fixed base 8, enhancing structural stability and preventing swaying due to water flow impact during sampling. The robotic arm 3 integrates a water pump assembly 5, and a water quality monitoring sensor is installed at the front end. The sensor probe directly contacts the water body, allowing real-time monitoring of multiple indicators such as pH, conductivity, and dissolved oxygen.

[0033] Fluid pH Detector 2: Built inside the air compressor 1, it is the core component for sediment treatment and water quality analysis, including filter 13, drying component, and detection module. Filter 13 adopts a multi-layer filter structure to separate sediment from water in the water sample; the drying component is a constant temperature heating device that dries the filtered sediment to remove moisture; the detection module is linked with Fluid pH Detector 2 to analyze parameters such as pH of the water body, and calculates the sediment concentration by combining the sediment weight and water sample volume.

[0034] Water pump assembly 5 and control system: Water pump assembly 5 is installed on robotic arm 3 and connected to fluid acid-base detector 2 through pipeline, which can extract a fixed amount of water sample; The control system is integrated inside the main body of the device and is electrically connected to components such as water quality monitoring sensor, fluid acid-base detector 2, air compressor 1, and robotic arm 3. It is responsible for controlling the coordinated work of each component (such as positioning of robotic arm 3, water pump water intake, filtration and drying start-up, etc.), and storing and transmitting monitoring data, supporting remote viewing and analysis.

[0035] Workflow

[0036] Sampling preparation: The control system starts the device according to the preset time or remote command. The robotic arm 3 adjusts its position through the hinge component and extends the water quality monitoring sensor and water pump inlet into the channel to a set depth.

[0037] Water quality monitoring: Water quality monitoring sensors directly contact the water body to measure indicators such as pH value, conductivity, and dissolved oxygen in real time, and the data is synchronously transmitted to the control system.

[0038] Water sample collection: The water pump assembly 5 is started to extract a fixed amount of water sample, which is then transported to the fluid acid-base detector 2 through the pipeline.

[0039] Sediment treatment: Water sample enters filter 13, sediment is intercepted, and clean water is discharged through the filter layer; the sediment separated by filter 13 is sent to the drying component, and moisture is removed after constant temperature drying.

[0040] Concentration calculation: The control system records the weight of the dried sediment and, in conjunction with the volume of the extracted water sample, automatically calculates the sediment concentration (sediment weight / water sample volume).

[0041] Data output: The control system integrates sediment concentration with various water quality indicators and sends them to the remote monitoring platform via a wireless transmission module. At the same time, it stores backup data locally, and the robotic arm 3 resets, waiting for the next monitoring cycle.

[0042] The specific embodiments of this utility model have been described in detail above, but they are merely examples, and this utility model is not equivalent to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to this utility model are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model should be covered within the scope of this utility model.
