Description

Technical Field

[0001] This utility model relates to the field of water quality testing instruments, and in particular to a water quality testing instrument based on big data. Background Technology

[0002] With the development of society and the economy, scientific progress, and the improvement of people's living standards, people's requirements for the quality of drinking water are constantly increasing, and drinking water quality standards are also constantly developing and improving accordingly. The formulation of drinking water quality standards is related to various factors such as people's living habits, culture, economic conditions, the level of scientific and technological development, water resources, and the current state of water quality. Drinking water standards primarily consider its impact on human health, and in addition to physical and chemical indicators, they also include microbiological indicators. For industrial water, the standards consider whether it affects product quality or easily damages containers and pipelines. Since the diffusion of substances in water requires a process, and traditional monitoring devices detect at fixed points, if the number of monitoring devices placed on the water surface in an area is relatively small, it can only reflect the water quality at a few points, making it impossible to accurately monitor the entire water area. Therefore, application number 202022527339.0 discloses a portable method based on big data usage. This invention relates to the field of water quality testing equipment technology. The mobile water quality testing equipment, based on big data, includes a shell with a drain outlet. A solar panel is fixedly connected to the upper surface of the shell. A rotating shaft is located at the front of the shell, with a paddle and a gear fixedly connected to its circumference. A water sample analyzer is fixedly connected to the middle of a water pipe, and a water pump is fixedly connected to the left end of the water pipe. A fixing block is fixedly connected to the lower surface of the water pump, and its lower surface is fixedly connected to the lower inner wall of the shell. The rotating shaft is rotatably connected to the rear of the fixing block, and the left side of the water pipe is fixedly connected to the right side of the water pipe. This allows the equipment to move within a certain range, monitoring the water quality within that range. It can reflect the water quality of the entire water area to a certain extent, greatly expanding the detection range and providing a more comprehensive water quality assessment.

[0003] The aforementioned patent discloses a mobile water quality testing device based on big data. This device can expand its detection range by moving within a certain area and monitoring the water quality within that range. However, it still has the following shortcomings during use: 1. While the water is being pumped by a pump, the water sampler detects the water in the flowing water. Because the water spends a short time in the pipe during flow, the detection effect is not ideal. 2. The fixed length of the pumping pipe results in a fixed depth for water extraction. Since water quality varies at different depths, sampling water at the same depth does not significantly improve the detection range, further affecting the detection effect. In light of the above, this application proposes a water quality testing device based on big data. Utility Model Content

It also allows for sampling and testing of water at different depths, significantly increasing the testing range compared to existing technologies that can only sample water at the same depth, further enhancing the testing effect. In addition, it can automatically filter, block, and clean impurities in the extracted water, improving the stability of water pumping and sampling. Attached Figure Description

In addition, it can automatically filter, block and clean impurities in the extracted water, improving the stability of water pumping and sampling.

[0030] Working principle: During use, the entire device can be moved by the moving mechanism. The specific moving process principle has been mentioned in the patent application number: 202022527339.0, and will not be elaborated here. During use, the solar panel 5 absorbs external solar energy and converts it into DC power, which is stored in the battery 17. The inverter 6 converts the DC power inside the battery 17 into AC power, which can power the water pump 102, water quality detector 104, water level sensor 3, solenoid valve 2, PLC controller 4 and electric telescopic rod 8.

[0031] When pumping water for testing, the PLC controller 4 first sets the pumping depth and the water level in the water tank 1 according to the testing requirements. After setting, the electric telescopic rod 8 is activated in the forward direction. The output shaft of the electric telescopic rod 8 drives the connecting block 10 to move downward. The connecting block 10 drives the extension tube 7 to move downward and extend into the water. The extension tube 7 also drives the waterproof magnetic sensor 14 to move downward. The waterproof magnetic sensor 14 detects the depth of the extension tube 7 and transmits its depth value to the PLC controller 4. When the depth value reaches the preset value, the PLC controller 4 controls the electric telescopic rod 8 to close. Then, the water pump 102 is turned on. The water pump 102 pumps water through the L-shaped extraction tube 103 and the extension tube 7. The pumped water is pumped into the water tank 1. The water level sensor 3 detects the water level inside the water tank 1 and transmits its water level value to the PLC controller 4. When the water level reaches the preset value, the PLC controller 4 controls the water pump 102 to turn off and stop pumping water. Simultaneously, the PLC controller 4 controls the water quality detector 104 to start detecting the water quality inside the water tank 1 and transmits the detected water quality data to the cloud database for storage. After the water quality detector 104 completes the detection, the PLC controller 4 controls the solenoid valve 2 to open, causing the water inside the water tank 1 to drain. When the water level sensor 3 detects that the water inside the water tank 1 has been drained, the PLC controller 4 controls the solenoid valve 2 to close, and the entire device can be moved to the next location for sampling and testing via the moving mechanism. By drawing water into the water tank 1 for testing and then draining it after testing, the water stays inside the water tank 1 for a longer period of time. Compared with the existing technology of testing flowing water, this detection method has a significantly improved detection effect. In addition, the adjustable insertion depth of the extension tube 7 into the water allows for sampling and testing of water at different depths. Compared with the existing technology that can only sample water at the same depth, the detection range is significantly increased, further improving the detection effect.

[0032] During the water extraction process through the extension tube 7, the filter screen 11 filters and blocks impurities in the water, reducing the likelihood of impurities entering the L-shaped extraction tube 103 with the water. The time interval for opening the brake motor 13 is preset by the PLC controller 4. When the opening time is reached, the PLC controller 4 controls the brake motor 13 to open. The output shaft of the brake motor 13 drives the toggle lever 12 to rotate, which in turn drives the rubber toggle strip 15 to rotate and clean the impurities at the bottom of the filter screen 11. By periodically cleaning the bottom of the filter screen 11, the blockage of the filter screen 11 by impurities can be effectively reduced, thus improving the stability of water sampling.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
