[0025] In water quality monitoring and treatment, water sampling is a fundamental and crucial step, serving as the data foundation for subsequent water quality analysis, evaluation, and decision-making. It is of great significance in areas such as drinking water safety, wastewater treatment and reuse, environmental monitoring and ecological protection, scientific research, and climate change studies. In the field of photovoltaic wastewater treatment, water quality monitoring and dosing equipment for photovoltaic manufacturing wastewater treatment is showing increasingly broad application prospects. These devices, with their unique integrated design, play an indispensable and crucial role in ensuring that photovoltaic manufacturing wastewater meets standards and maintaining ecological stability. They can not only efficiently monitor the complex and diverse pollutant indicators in photovoltaic manufacturing wastewater, but also accurately add chemicals based on the monitoring results to ensure proper wastewater purification, thereby powerfully promoting the green and sustainable development of the photovoltaic industry.

[0026] However, current water quality monitoring and chemical dosing equipment often uses fixed pipette sampling, which limits sampling to localized water bodies and fails to cover different locations within complex wastewater systems. This small-scale sampling results in unrepresentative water samples, leading to biases in water quality monitoring and analysis, affecting the accurate assessment of water quality. Furthermore, it can cause inaccuracies in subsequent chemical dosing, resulting in wasted chemicals, increased costs, and even secondary damage to the aquatic environment.

[0027] In view of the sampling limitations of current water quality monitoring and dosing equipment, the following describes in detail the overall structure, working principle and technical effects of the wastewater treatment water quality monitoring and dosing equipment provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0028] Please refer to Figures 1-4 This utility model provides a wastewater treatment water quality monitoring device and dosing equipment, applied in the field of wastewater treatment, for monitoring wastewater quality and performing chemical dosing treatment. Specifically, in this embodiment, the wastewater treatment water quality monitoring and dosing equipment is applied in the field of photovoltaic wastewater treatment. While efficiently monitoring the complex and diverse pollutant indicators in photovoltaic manufacturing wastewater, it can also accurately dosing treatment based on the monitoring results, ensuring proper purification of the wastewater and thus powerfully promoting the green and sustainable development of the photovoltaic industry.

[0029] On the one hand, please refer to Figure 1 The present invention provides a wastewater treatment dosing device, including a wastewater treatment water quality monitoring device 100 and a dosing tank 200. The water quality monitoring device 100 has a mounting cover 110 and a monitoring box 160 mounted on the mounting cover 110. The monitoring box 160 is used to monitor and analyze the collected water samples. The dosing tank 200 is mounted on the mounting cover 110 and is connected to the monitoring box 160.

[0030] Furthermore, two water level sensors 210 are installed on one side of the dosing tank 200, positioned vertically to detect the liquid level within the tank and prevent overflow or emptying. At least one sealed container 220 is connected to the top of the dosing tank 200, with a metering valve 230 between the sealed container 220 and the dosing tank 200. Different sealed containers 220 can be filled with different agents, such as coagulants, flocculants, pH adjusters, and disinfectants. Based on the wastewater quality in the monitoring tank 160, different metering valves 230 are opened to deliver the appropriate dosage of the agent to the dosing tank 200, achieving targeted purification of the wastewater and improving purification efficiency.

[0031] On the other hand, please refer to Figures 2-4This utility model also provides a wastewater treatment water quality monitoring device 100, which is applied to the above-mentioned wastewater treatment dosing equipment for sampling and monitoring wastewater quality. The wastewater treatment water quality monitoring device 100 provided by this utility model includes a mounting cover 110, a sampling tube 120, a drive assembly 130, a stirring paddle 140, a transmission assembly 150, and a monitoring box 160. The mounting cover 110 is a hollow rectangular box structure with openings at both the top and bottom. The sampling tube 120 is installed inside the mounting cover 110, and the length direction of the sampling tube 120 is perpendicular to the length direction of the mounting cover 110. The lower liquid inlet end of the sampling tube 120 extends from the lower opening of the mounting cover 110 to the outside of the mounting cover 110. The drive assembly 130 is disposed on the mounting cover 110 and connected to the sampling tube 120. The drive assembly 130 is used to drive the sampling tube 120 to move along the length direction of the mounting cover 110. Furthermore, the stirring paddle 140 is installed at the lower liquid inlet end of the sampling tube 120. The transmission assembly 150 is disposed on both the sampling tube 120 and the mounting cover 110, connected to the stirring paddle 140, and used to drive the stirring paddle 140 to rotate. The monitoring box 160 is mounted on the mounting cover 110 and connected to the sampling tube 120. A water pump 161 is also installed between the monitoring box 160 and the sampling tube 120 to pump wastewater into the monitoring box 160 through the sampling tube 120. Furthermore, at least one monitoring probe 162 is located inside the monitoring box 160 for monitoring the wastewater sample inside the monitoring box 160.

[0032] By installing a drive assembly 130 on the mounting cover 110, the sampling tube 120 is moved along the length of the mounting cover 110, thereby increasing the sampling range of the sampling tube 120 when sampling wastewater and covering different locations of the wastewater. Furthermore, during the sampling process, the transmission assembly 150 drives the stirring paddle 140 to rotate, stirring the wastewater at the inlet end of the sampling tube 120 to improve the uniformity of the sampled wastewater and avoid the problem of insufficient representativeness of water samples in existing sampling methods, which can easily lead to biases in water quality monitoring and analysis.

[0033] Please refer to Figure 2 In some optional embodiments, the drive assembly 130 includes a motor 131, a screw 132, and a guide rod 133. The screw 132 is rotatably mounted inside the mounting cover 110 along its length, and the guide rods 133 are also disposed inside the mounting cover 110 along its length. The screw 132 and the guide rods 133 are parallel. Furthermore, the screw 132 is threaded through the sampling tube 120, and the guide rods 133 are slidably passed through the sampling tube 120. The motor 131 is mounted on the outside of the mounting cover 110, and the output shaft of the motor 131 extends toward the inside of the mounting cover 110. The output shaft of the motor 131 is coaxially connected to the screw 132.

[0034] The motor 131 drives the screw 132 to rotate, which in turn drives the sampling tube 120 to move along the length of the mounting cover 110. During the movement of the sampling tube 120, the guide rod 133 plays a guiding role, thereby facilitating the movement of the sampling tube 120 and expanding the wastewater sampling range of the sampling tube 120.

[0035] In some alternative embodiments, the drive assembly 130 may also include one of the linear reciprocating mechanisms such as a piston rod, a gear rack, a crank rocker, or a linear motor, as long as the drive assembly 130 can drive the sampling tube 120 to reciprocate along the length of the mounting cover 110.

[0036] For further details, please refer to Figures 1-4 The transmission assembly 150 includes a rotating shaft 151, a gear 152, and a toothed plate 153. The rotating shaft 151 is coaxially rotatably mounted on the sampling tube 120, with both ends extending outside the sampling tube 120. The gear 152 is coaxially mounted on the upper end of the rotating shaft 151, and the stirring paddle 140 is coaxially mounted on the lower end of the rotating shaft 151. The toothed plate 153 is mounted on the mounting cover 110 along its length, and meshes with the gear 152. By configuring the transmission assembly 150, when the drive assembly 130 drives the sampling tube 120 to move along the length of the mounting cover 110, the gear 152 meshing with the toothed plate 153 rotates, thereby driving the rotating shaft 151 to rotate, thus achieving the effect of driving the stirring paddle 140 to rotate. The stirring paddle 140 is linked with the drive assembly 130. When the drive assembly 130 drives the sampling tube 120 to move, it drives the stirring paddle 140 to rotate. Thus, when the sampling tube 120 moves, the stirring paddle 140 is used to stir the wastewater, further increasing the sampling range of the sampling tube 120 and improving the uniformity of the water sample during wastewater sampling.

[0037] Please refer to Figure 4 In some alternative embodiments, a filter plate 121 is provided at the lower liquid inlet end of the sampling tube 120. The filter plate 121 is used to filter the wastewater entering the sampling tube 120 to prevent solid impurities in the wastewater from entering the sampling tube 120 and causing blockage, thus affecting sampling. It should be noted that the rotating shaft 151 rotates through the filter plate 121. Furthermore, to prevent solid impurities in the wastewater from clogging the filter plate 121 and affecting the liquid inlet of the sampling tube 120, in some alternative embodiments, a scraper 122 is provided on the side of the filter plate 121 away from the mounting box. The scraper 122 is connected to the rotating shaft 151. When the rotating shaft 151 rotates, it drives the scraper 122 to rotate. During the rotation of the scraper 122, it scrapes and cleans the surface of the filter plate 121, thereby preventing blockage. Preferably, the distance between the scraper 122 and the filter plate 121 is 1mm-3mm.

[0038] Please refer to Figure 3 and Figure 4 The bottom of the sampling tube 120 expands to form an expansion section 123, which is inverted funnel-shaped, thereby increasing the diameter of the liquid inlet end of the sampling tube 120 and improving the liquid inlet efficiency. Furthermore, the water pump 161 is connected to the sampling tube 120 via a telescopic hose 170. By providing the telescopic hose 170, the hose deforms accordingly during the reciprocating movement of the sampling tube 120 within the mounting cover 110, preventing the water pump 161 from detaching from the sampling tube 120. The telescopic hose 170 is connected to the expansion section 123 of the sampling tube 120, and the gap between the telescopic hose 170 and the filter plate 121 is 3mm-5mm.

[0039] In summary, the implementation principle of the water quality monitoring device and dosing equipment provided by this utility model is as follows: By setting a driving component 130 on the mounting cover 110, the sampling tube 120 is driven to move along the length direction of the mounting cover 110, thereby increasing the sampling range of the sampling tube 120 when sampling wastewater and covering different locations of the wastewater. Furthermore, during the sampling process, the transmission component 150 drives the stirring paddle 140 to rotate, stirring the wastewater at the inlet end of the sampling tube 120 to improve the uniformity of the sampled wastewater and avoid the problem of insufficient representativeness of water samples in existing sampling methods, which can easily lead to deviations in water quality monitoring and analysis.

[0040] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes 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.
