Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, specifically to an embedded electrochemical water quality testing device. Background Technology

[0002] In the field of water quality testing, accurately and efficiently acquiring electrochemical and optical characteristics of water is crucial for assessing water quality, ensuring water safety, and guiding water treatment processes. Electrochemical detection technology, based on the electrochemical properties of substances, analyzes the content of specific substances in a water sample by measuring electrochemical signals such as potential and current between the electrode and the solution. For example, ion-selective electrodes can detect the concentration of various ions in a water sample, such as calcium, magnesium, and chloride ions; redox electrodes can determine the content of substances with redox properties, such as heavy metal ions and organic pollutants. This detection technology has advantages such as high sensitivity, good selectivity, and fast response speed, and has been widely used in environmental monitoring, industrial process control, and other fields.

[0003] Most existing water quality testing equipment adopts a single-test mode, meaning that each test requires re-collecting water samples, installing detection probes or sensors, and performing a series of preparatory tasks. This single-test method is not only cumbersome and time-consuming, but also cannot achieve real-time, continuous monitoring of water quality. For example, in industrial production processes, fluctuations in water quality can significantly impact production equipment and product quality. If a single-test method is used, it is difficult to detect changes in water quality in a timely manner, thus failing to adjust production process parameters promptly, potentially leading to production accidents or a decline in product quality. In the field of environmental monitoring, for water quality monitoring of rivers, lakes, and other water bodies, single-tests cannot capture changes in water quality over time, making it difficult to comprehensively and accurately assess the pollution status and trends of water bodies. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an embedded electrochemical water quality detection device, which solves the problems mentioned in the background art.

[0005] The solution of this utility model to the above-mentioned technical problems is as follows: An embedded electrochemical water quality detection device includes: Tabletop; A water storage tank is installed on the table. An electrochemical detection head is installed inside the water storage tank for electrochemical detection of water quality; An optical detection system, mounted on the table, includes a transparent tube, a backlight panel, and an industrial camera. The backlight panel and the industrial camera are located on opposite sides of the transparent tube and are used to perform optical detection of water flow through the transparent tube. A circulation system includes a first water pump, the pump's pumping end being connected to the water storage tank, its outlet end being connected to the inlet end of the transparent pipe, and the transparent pipe's outlet end being connected to the water storage tank, for circulating water between the water storage tank and the transparent pipe; The water inlet system includes an inlet pipe and a return pipe, which are connected to the water storage tank via a solenoid valve and are used to supply water to and return water to the water storage tank. The drainage system includes a second water pump, the pump's pumping end being connected to the bottom of the water storage tank, and its outlet end being connected to a drain pipe, for draining water from the water storage tank.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the water storage tank is mounted on the table via a limiting bracket; the inlet pipe and the return pipe are mounted on a support, which is located on the table and on one side of the water storage tank.

[0008] The beneficial effects of adopting the above-mentioned further solutions are: The water tank is securely mounted on the table using a limiting bracket, effectively preventing it from shaking or shifting during operation due to water flow impact or device vibration. This ensures the stability of the water tank and consequently guarantees the accuracy and reliability of the electrochemical detection head when testing water samples. Simultaneously, the inlet and outlet pipes are installed on a bracket located on one side of the water tank, resulting in a compact and rational layout for the entire inlet and outlet structure. This facilitates pipe installation and maintenance, saves space, and makes the overall device more concise and organized.

[0009] Furthermore, the electrochemical detection head is mounted at the end of the bracket and inserted into the water storage tank.

[0010] The beneficial effects of adopting the above-mentioned further solutions are: The electrochemical detection head is mounted on the end of the bracket and inserted into the water tank. This installation method makes the installation and removal of the detection head extremely convenient. When calibration, repair, or replacement of the detection head is required, it can be easily removed or installed from the water tank, greatly improving maintenance efficiency. Moreover, the insertion method ensures that the detection head has full contact with the water sample, accurately acquiring the electrochemical information of the water sample, thereby improving the accuracy of water quality testing.

[0011] Furthermore, the optical detection system also includes a mounting bracket, which is disposed on the table and located on the side of the water tank away from the support; the transparent tube and the backlight plate are mounted on the mounting bracket, and the backlight plate is located behind the transparent tube.

[0012] The beneficial effects of adopting the above-mentioned further solutions are: The mounting bracket provides a stable and reliable platform for the transparent tube and backlight panel, ensuring they do not shift or shake due to external factors during operation, thus guaranteeing the stability of optical detection. Positioning the bracket on the side of the water tank away from the support makes efficient use of space and results in a more scientific and rational layout of the entire device. The backlight panel, located behind the transparent tube, provides a uniform and stable light source for the water flow within the tube, allowing the industrial camera to clearly capture changes in light as it passes through the water, thereby accurately acquiring optical characteristics of the water quality and improving the accuracy of optical detection.

[0013] Furthermore, the industrial camera is mounted on the bracket via a mounting base and is located in front of the transparent tube.

[0014] The beneficial effects of adopting the above-mentioned further solutions are: The industrial camera is securely mounted on the frame using a mounting bracket and precisely positioned in front of the transparent tube. This ensures a constant relative position between the camera and the tube, guaranteeing consistent shooting angles and distances for each shot, thus improving image quality and consistency. This mounting method also facilitates camera adjustment and maintenance. Adjustments to shooting parameters or camera cleaning are easily performed, contributing to the long-term stable operation of the optical inspection system.

[0015] Furthermore, the inlet pipe and the return pipe are connected via the solenoid valve.

[0016] The beneficial effects of adopting the above-mentioned further solutions are: By connecting the inlet and outlet pipes with a solenoid valve, precise control of the water flow direction is achieved. When water needs to be supplied to the storage tank, the solenoid valve opens the corresponding channel, allowing water to smoothly enter the tank. After the test is completed, if it is necessary to return the water to the original source, the solenoid valve can promptly change the water flow direction, allowing the water to flow back through the outlet pipe. This control method is flexible and convenient, enabling quick and accurate adjustment of the water flow state according to actual needs, thus improving the automation level and ease of operation of the device.

[0017] Furthermore, the first water pump is mounted on the tabletop and located on one side of the mounting bracket.

[0018] The beneficial effects of adopting the above-mentioned further solutions are: Placing the first water pump on the table ensures its installation stability, allowing it to operate smoothly during work and reducing noise and malfunctions caused by vibration. The layout, located on one side of the mounting bracket, makes full use of space, allowing for a more compact and rational connection between the first water pump and the optical detection system. This facilitates pipe laying and connection, reduces pipe length and bends, lowers water flow resistance, and improves the pump's pumping efficiency. This, in turn, ensures rapid and stable water circulation between the storage tank and the transparent tube, thus enhancing detection efficiency.

[0019] Furthermore, the second water pump is located at the bottom end of the tabletop.

[0020] The beneficial effects of adopting the above-mentioned further solutions are: By placing the second water pump at the bottom of the tabletop, the space beneath the device is fully utilized, resulting in a more compact structure that does not occupy the operating space above the table, allowing staff to perform other tasks on the table. This arrangement also facilitates heat dissipation for the second water pump, as the area under the tabletop typically has good ventilation, accelerating the dissipation of heat generated during pump operation, extending the pump's lifespan, and ensuring the stable and reliable operation of the drainage system.

[0021] This invention provides an embedded electrochemical water quality detection device. It has the following advantages: This device integrates both electrochemical and optical detection methods. The electrochemical detection head, located inside the water tank, performs electrochemical analysis of the water quality. Based on electrochemical principles, it measures electrochemical parameters in the water sample, such as conductivity and redox potential, to accurately obtain key information such as ion concentration and chemical content. The optical detection system utilizes a transparent tube, a backlight panel, and an industrial camera. Based on the absorption and scattering characteristics of light by water, it captures changes in light as it passes through the water flow, thereby obtaining optically relevant information such as turbidity, color, and particulate matter distribution. These two detection methods complement each other, enabling a comprehensive and integrated assessment of water quality, significantly improving the accuracy and reliability of the detection.

[0022] The circulation system includes a first water pump, whose pumping end is connected to a water storage tank, and its outlet end is connected to the inlet end of a transparent tube. The outlet end of the transparent tube is also connected to the water storage tank. This design allows water to circulate between the water storage tank and the transparent tube. During operation, the first water pump uses mechanical energy to draw water from the water storage tank and deliver it to the transparent tube, ensuring a continuous and stable water flow within the transparent tube for optical detection. Simultaneously, the circulating water sample makes the water sample detected by the electrochemical detection head more representative, avoiding the influence of local water sample differences on the detection results and improving the consistency and repeatability of the detection.

[0023] The water inlet system consists of an inlet pipe, a return pipe, and a solenoid valve, which connects to the water storage tank. The solenoid valve precisely controls the flow of water into the tank, opening when water needs to be supplied and introducing external water. After testing, if water needs to be returned to its original source, the solenoid valve is reopened, allowing water to flow back through the return pipe. The drainage system is equipped with a second pump, whose suction end is connected to the bottom of the water storage tank, and its outlet end is connected to the drain pipe. When the tank needs to be emptied, the second pump uses mechanical energy to pump water out and discharge it to a designated location. This water supply and drainage system is flexible and convenient, meeting the water demand and drainage requirements of different scenarios.

[0024] Because the water sample circulates rapidly in the circulation system, the electrochemical detection head and optical detection system can simultaneously detect the water sample without waiting for it to settle or performing different tests in stages, greatly shortening the detection time. Furthermore, the rational structural design ensures smooth connections between components, reducing detection delays caused by improper installation or connection problems, thereby improving the overall detection efficiency of the device and meeting the needs for rapid water quality testing.

Moreover, the insertion method ensures that the detection head 16 has full contact with the water sample, accurately acquiring the electrochemical information of the water sample, thereby improving the accuracy of water quality testing.

[0032] Example 3: To optimize the stability and accuracy of the optical detection system, for example, such as Figures 1 to 4 As shown, this utility model also includes: The optical inspection system also includes a mounting bracket 9, which is set on the table 1 and located on the side of the water tank 2 away from the support 13. The transparent tube 7 and the backlight plate 8 are mounted on the mounting bracket 9, with the backlight plate 8 positioned behind the transparent tube 7. The mounting bracket 9 provides a stable and reliable mounting platform for the transparent tube 7 and the backlight plate 8, ensuring that they will not shift or shake due to external factors during operation, thus guaranteeing the stability of the optical inspection. Positioning the mounting bracket 9 on the side of the water tank 2 away from the support 13 makes efficient use of space, resulting in a more scientific and rational layout of the entire device.

[0033] The industrial camera 6 is mounted on the mounting bracket 9 via the mounting base 5, positioned in front of the transparent tube 7. The mounting base 5 securely mounts the industrial camera 6 to the mounting bracket 9 and precisely positions it in front of the transparent tube 7, ensuring a constant relative position between the industrial camera 6 and the transparent tube 7. This guarantees consistent shooting angles and distances for each shot, improving the quality and consistency of the captured images. This mounting method facilitates the debugging and maintenance of the industrial camera 6. Adjustments to shooting parameters or cleaning of the camera can be easily performed, contributing to the long-term stable operation of the optical inspection system.

[0034] Example 4: To enhance the water flow control capability and operational stability of the device, for example, such as Figures 1 to 4 As shown, this utility model also includes: The inlet pipe 11 and the return pipe 12 are connected by a solenoid valve 10, which enables precise control of the water flow direction. When water needs to be supplied to the storage tank 2, the solenoid valve 10 can open the corresponding channel, allowing water to smoothly enter the storage tank 2. After the detection is completed, if it is necessary to return the water to the original water source, the solenoid valve 10 can promptly change the water flow direction, allowing the water to flow back through the return pipe 12. This control method is flexible and convenient, and can quickly and accurately adjust the water flow state according to actual needs, improving the automation level and ease of operation of the device.

[0035] The first water pump 4 is mounted on the tabletop 1 and located on one side of the mounting bracket 9. This placement ensures the pump's installation stability, allowing it to operate smoothly during operation and reducing noise and malfunctions caused by vibration. The layout, located on one side of the mounting bracket 9, makes full use of space, allowing for a more compact and rational connection between the first water pump 4 and the optical detection system. This facilitates pipe laying and connection, reduces pipe length and bends, lowers water flow resistance, and improves the pump's pumping efficiency. This, in turn, ensures rapid and stable water circulation between the storage tank 2 and the transparent pipe 7, thereby improving detection efficiency.

[0036] The second water pump 14 is located at the bottom of the tabletop 1. This placement makes full use of the space beneath the device, resulting in a more compact structure that does not occupy the operating space above the table, allowing staff to perform other tasks on the table. Simultaneously, this arrangement also facilitates heat dissipation for the second water pump 14, as the area under the tabletop 1 typically has good ventilation, accelerating the dissipation of heat generated during pump operation, extending the pump's lifespan, and ensuring the stable and reliable operation of the drainage system.

[0037] Working principle: The inlet pipe 11 and the return pipe 12 are connected to the water storage tank 2 via the solenoid valve 10. When the solenoid valve 10 is opened, external water enters the water storage tank 2 through the inlet pipe 11, providing a water sample for subsequent testing. The solenoid valve 10 controls the opening and closing of the pipes to achieve the delivery of water to the water storage tank 2.

[0038] An electrochemical detection head 16 is installed inside the water storage tank 2. Once water is present in the tank, the electrochemical detection head 16 begins operation, performing electrochemical detection on the water quality within the tank. It obtains relevant water quality information by measuring the electrochemical parameters in the water sample. Based on electrochemical principles, the detection head 16 reacts electrochemically with substances in the water sample, converting chemical information into electrical signals for analysis.

[0039] The first water pump 4 is mounted on the tabletop 1. Its pumping end is connected to the water storage tank 2, and its outlet end is connected to the inlet end of the transparent pipe 7. The outlet end of the transparent pipe 7 is also connected to the water storage tank 2. When the first water pump 4 is turned on, it draws water from the water storage tank 2 and delivers it to the transparent pipe 7, causing the water to circulate between the water storage tank 2 and the transparent pipe 7. The first water pump 4 uses mechanical energy to pump water from a lower position to a higher position and propels the water to circulate in the pipeline.

[0040] The optical inspection system includes a transparent tube 7, a backlight panel 8, and an industrial camera 6. The backlight panel 8 and the industrial camera 6 are located on opposite sides of the transparent tube 7.

The industrial camera 6 is mounted on the mounting bracket 9 via a mounting base 5 and is positioned in front of the transparent tube 7. When water flows in the transparent tube 7, light emitted by the backlight panel 8 passes through the water in the transparent tube 7. The industrial camera 6 captures the light passing through the water, and the optical information related to the water quality is obtained by analyzing the captured images. Utilizing the absorption and scattering properties of water on light, the industrial camera 6 captures changes in light to reflect the water quality status.

[0041] After the test is completed, if it is necessary to return the water to the original water source, the solenoid valve 10 can be opened to allow the water in the storage tank 2 to flow back to the original location through the return pipe 12. The solenoid valve 10 controls the opening and closing of the pipe to achieve water return. The second water pump 14 is located at the bottom of the table 1, with its suction end connected to the bottom of the storage tank 2 and its outlet end connected to the drain pipe 15. When it is necessary to empty the water in the storage tank 2, the second water pump 14 is turned on to draw out the water from the storage tank 2 and discharge it through the drain pipe 15. The second water pump 14 uses mechanical energy to draw water from the bottom of the storage tank 2 and discharge it to the designated location.
