Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a surface water pollutant verification detection device. Background Technology

[0002] Currently, the detection of pollutants in surface water mainly relies on two technical methods: Laboratory analysis method: This method follows the process of on-site sampling, sample preservation and transportation, and laboratory instrument analysis. Its advantage is high detection accuracy, but the process is cumbersome, time-consuming and labor-intensive, and it cannot meet the needs of rapid on-site response to pollution incidents, resulting in poor timeliness.

[0003] On-site testing method: This method uses portable equipment to analyze water quality directly on-site. Its advantages are speed and convenience, but it typically involves single-point sampling at a fixed depth, making it impossible to obtain samples from different depths and locations within the water body. This makes it difficult to accurately reflect the spatial distribution of pollutants, leading to biased monitoring data and a high risk of misjudgment. Furthermore, the existing equipment has fragmented functions, resulting in difficult deployment, complex operation, and high maintenance costs, making long-term unattended automated monitoring difficult. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides a surface water pollutant verification detection device. To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

Detailed Implementation

[0016] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] like Figure 1-3 As shown in some illustrative embodiments, a surface water pollutant verification detection device is provided, including: a twin-body floating platform 100, a sinking structure 200, a sampling component 300, an in-situ detection chamber 400, a control energy chamber 500, and a solar panel 600.

[0018] The catamaran floating platform 100 serves as a stable base for water operations. It adopts a catamaran structure, consisting of two floating compartments 110. Each compartment 110 is welded from high-strength polyethylene or stainless steel and filled with foam material to provide additional buoyancy. The two floating compartments 110 are connected by a floating support 120, which is constructed of high-strength aluminum alloy profiles and features a truss structure design. This design ensures connection strength while reducing overall weight, and also provides installation space for the central submerged structure 200.

[0019] Compared to monohulls or small boats, catamaran structures have a larger waterline area, making this application more stable, especially during the sinking of the central lifting column 210, providing sufficient stability so that the telescopic sampling head can be accurately aligned, thereby ensuring the authenticity of the test data.

[0020] The sinking structure 200 is positioned between the two floating chambers 110. Specifically, the upper half of the sinking structure 200 is vertically positioned at the center of the floating support 120, while the lower half extends into the water body to adjust the water level depth of the sampling component 300, thereby obtaining water samples at different depths. The sinking structure 200 includes: a central lifting column 210, a first motor 220, a worm gear screw transmission mechanism 230, a rotary mechanism 240, and a second motor 250 for driving the rotary mechanism 240 to rotate.

[0021] The central lifting column 210 can adopt a multi-section sleeve structure as used in the prior art, and the material is corrosion-resistant titanium alloy or 316L stainless steel. In this application, the central lifting column 210 is a hollow structure, with a cable channel 260 and a sample channel 270 inside. The cable channel 260 is used to lay wiring harnesses. For example, the wiring harness connecting the second motor 250 and the control energy compartment 500 passes through the cable channel 260. Similarly, the wiring harness connecting the peristaltic pump 340 in the telescopic sampling head and the motor driving the telescopic mechanism 320 to extend and retract, and the control energy compartment 500, can also pass through the cable channel 260. The sample channel 270 provides space for the silicone tube 370, so that the sample collected by the telescopic sampling head can be transported to the in-situ detection compartment 400 via the sinking structure 200.

[0022] The power output end of the first motor 220 is connected to the central lifting column 210 through a worm gear screw transmission mechanism 230. The first motor 220 is either a servo motor or a stepper motor. The first motor 220 drives the screw to rotate, and the central lifting column 210 is connected to the screw nut. When the screw nut moves up and down, the central lifting column 210 also extends / retracts synchronously. At the same time, in order to ensure that the central lifting column 210 only performs linear motion and does not twist, it is constrained by a linear guide rail or guide sleeve.

[0023] The slewing mechanism 240 can be an existing slewing bearing mechanism, which is driven by the second motor 250 to achieve rotation of the power output end. The top of the central lifting column 210 is connected to the float support 120, and the slewing mechanism 240 is located at the bottom of the central lifting column 210. The sampling component 300 is located at the bottom of the sinking structure 200, that is, connected to the power output end of the slewing mechanism 240. Specifically, the sampling component 300 is located on the slewing mechanism 240, so that the sampling component 300 can rotate at the bottom of the central lifting column 210.

[0024] The sampling assembly 300 includes a sampling cantilever 310 extending radially along the sunken structure 200 and telescopic sampling heads alternately arranged on both sides of the sampling cantilever 310.

[0025] The sampling cantilever 310 can be designed in a straight line or a cross shape, with each arm being 1-2 meters long. The sampling cantilever 310 has a hollow structure, with internal channels connecting to the cable channel 260 and the sample channel 270. The middle part of the sampling cantilever 310 is connected to the bottom of the rotating mechanism 240. The telescopic sampling head is perpendicular to the sampling cantilever 310 and extends away from the sampling cantilever 310 to simultaneously collect water samples from disturbed areas at different locations away from the main body of the device.

[0026] The telescopic sampling head includes: a telescopic mechanism 320, a water sampling port 330, a peristaltic pump 340, a filter 350, and a one-way valve 360. The telescopic mechanism 320 has a hollow structure.

[0027] A water sampling port 330 is located at the end of a telescopic mechanism 320. The telescopic mechanism 320 can integrate a small DC motor-driven lead screw or rack and pinion mechanism to extend and retract the water sampling port 330. A filter 350 is installed at the opening of the water sampling port 330 to prevent large debris from clogging it, and a one-way valve 360 ​​is also installed. The water sampling port 330 is connected to the in-situ detection chamber 400 via a silicone tube 370, which is located within the sample channel 270. When the peristaltic pump 340 operates, it draws water into the water sampling port 330, processes it through the filter 350, and then it enters the silicone tube 370. Multiple telescopic sampling heads simultaneously collect water samples.

[0028] The in-situ detection chamber 400 and the control and energy chamber 500 are respectively located in two floating chambers 110.

[0029] The in-situ detection chamber 400 includes: a chamber body 410 and a robotic arm 420, a detector 430 and several sample storage boxes 440 disposed inside the chamber body 410. The sample storage boxes 440 are connected to the water sampling port 330 through silicone tubes 370, and each sample storage box 440 corresponds to one water sampling port 330.

[0030] The control energy compartment 500 is used to control the operation, energy supply and remote data transmission of the entire device. Specifically, it includes a housing 510 and a controller 520, a battery 530 and a wireless transmission unit 540 installed inside the housing 510.

[0031] The robotic arm 420 can be a small six-axis robotic arm with a replaceable gripper or suction cup at its end for precisely grasping the sample storage container 44 and operating the detector's switches. The detector 430 adopts a modular design and can be flexibly configured according to monitoring needs; for example, a spectral module for routine parameters, a fluorescence module for specific organic compounds, and a microscope flow field module for bioanalysis. The controller 520 uses a programmable logic controller or an embedded industrial computer to run customized monitoring software. The wireless transmission unit 540 integrates multiple communication methods, prioritizing Wi-Fi or 4G / 5G.

[0032] Solar panels 600 are mounted on the floating support 120 to provide supplemental power for the operation of the entire device.

[0033] The device described in this application navigates or is towed to the target monitoring area via a GPS module or remote command. The controller 520 activates the first motor 220, which drives the central lifting column 210 to descend or rise vertically via a worm gear screw transmission mechanism 230, precisely adjusting the sampling component 300 to a preset sampling depth (such as 5 meters or 10 meters below the water surface, or at water stratification). The catamaran-type structure design ensures that the platform itself will not tilt significantly during this process due to the lifting and lowering movements.

[0034] Upon reaching the target depth, the controller 520 activates the second motor 250, driving the rotary mechanism 240 to rotate the entire sampling assembly 300 to a predetermined angle. Subsequently, multiple telescopic sampling heads extend synchronously from the sampling cantilever 320, simultaneously and independently collecting water samples from their respective locations. The water samples collected by the telescopic sampling heads are transported directly through their connected silicone tubes 370, driven by the peristaltic pump 340, via the sample channel 270 to the sample storage box 440 of the in-situ detection chamber 400, awaiting detection.

[0035] The robotic arm 420 inside the in-situ detection chamber 400 grasps the sample storage box 440 to obtain the water sample to be tested, and then sequentially sends it into the analyzer 430 for analysis. The water quality analyzer can quickly screen for routine indicators such as pH, temperature, dissolved oxygen, turbidity, conductivity, COD, and ammonia nitrogen. The microscopic flow field analyzer automatically performs microscopic imaging and counting analysis on suspended particles such as algae, zooplankton, and microorganisms in the water sample, providing biological pollution information.

[0036] The controller 520 receives and analyzes the test data in real time. When an abnormality or exceedance of a certain indicator is detected, the system executes a verification procedure, which controls the sampling component 300 to perform a second sampling and verification of the same suspicious point. Moreover, after confirming the abnormality, the robotic arm 420 automatically removes and properly stores the sample in a specific area of ​​the in-situ testing chamber 400, awaiting manual retrieval or retrieval by equipment such as drones, and sends it to the laboratory for high-precision quantitative analysis.

[0037] Information such as detection data, GPS location, and device status is transmitted back to the cloud monitoring center in real time via the wireless transmission unit 540. Simultaneously, the solar panel 600 continuously charges the battery 530, and the energy management module of the controller 520 intelligently allocates energy based on the device load and battery status to ensure uninterrupted system operation.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
