Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to an automatic water sample detector. Background Art

[0002] Automatic water sample analyzers are devices used to automatically analyze the various chemical components or physical properties of water samples. They are commonly used in environmental monitoring, water quality monitoring, industrial process control, and scientific research. They can efficiently and accurately analyze various parameters in water samples, such as pH, dissolved oxygen, conductivity, turbidity, chemical oxygen demand, ammonia nitrogen, nitrate, phosphate, and more.

[0003] For example, an automated water quality detector disclosed in authorization publication number CN218445458U includes a floating hull, a support base, and a water quality display screen. The support base is mounted inside the floating hull, the water quality display screen is fixedly mounted on the upper surface of the support base, a water quality detection probe is fixedly mounted on the bottom of the floating hull, a protective cover is mounted on the front side of the floating hull, and a rotating frame is rotatably connected to the upper side of the floating hull. By adopting the above technical solution, the beneficial effect of the utility model is that the controller displays the detection results of the water quality detection probe on the water quality display screen, facilitating the operator to conduct long-term fixed-point water quality detection information.

[0004] Although the above patent makes it convenient for operators to conduct long-term fixed-point detection of water quality information, the water quality detection probe is exposed under the equipment. Firstly, the probe is easily damaged by objects floating in the water. At the same time, since it does not filter large-volume debris, it is also likely to be blocked. Secondly, when the equipment is taken out of the water, the probe cannot be placed stably because it extends out from the bottom of the equipment. Utility Model Content

[0016] 1. This is an automatic water sample detector, which is used in conjunction with the detector body, bottom shell, circulation pump, suction pipe, drain pipe and water quality sensor. After the circulation pump is started, the water sample to be tested is sucked in from the bottom of the suction pipe, and then pumped into the second water tank through the drain pipe. As the water sample is sucked in, the water level continues to rise until the water level rises to the first water tank and is detected by the water quality sensor. At this time, the circulation pump is turned off, and the water quality sensor remotely transmits the detected water sample data to an external receiving end. After the detection is completed, the circulation pump is reversed to reversely pump out the water in the first and second water tanks and discharge it through the suction pipe. Since the water quality sensor is arranged inside the equipment, it will not be damaged by impact from floating objects on the water surface, and the bottom end of the top shell is horizontal, so it is more stable when taken out of the water and placed on the ground.

The device is equipped with a filter at the lower end of the water suction pipe, and a filter screen between the water tank one and the water tank two. The filter can block debris floating on the water surface, and the filter screen can filter the debris sucked into the water suction pipe, so as to avoid blockage of the delivery pipeline caused by large-volume debris, and the detected water sample data is more accurate.

[0026] In this embodiment, the output of the water quality sensor 10 is connected to the input port of the microcontroller 8, the power supply of the circulation pump 12 is controlled by the output port of the microcontroller 8, the communication module 7 is connected to the microcontroller 8, and the power module 6 provides power to the microcontroller 8, the communication module 7, the circulation pump 12 and the water quality sensor 10;

[0027] During the detection, the remote control circulation pump 12 is started. After the circulation pump 12 is started, the water sample to be tested is sucked in from the bottom of the suction pipe 13, and then pumped into the water tank 2 11 through the drain pipe 16. As the water sample is sucked in, the water level continues to rise until the water level rises to the water tank 1 9 and is detected by the water quality sensor 10. At this time, the circulation pump 12 is turned off, and the water quality sensor 10 remotely transmits the detected water sample data to the external receiving end. After the detection is completed, the circulation pump 12 is reversed to reversely extract the water in the water tank 1 9 and the water tank 2 11 and discharge it through the suction pipe 13. Since the water quality sensor 10 is arranged inside the equipment, it will not be damaged by impact of floating objects on the water surface, and the bottom end of the top shell 4 is horizontal, so it is more stable when taken out of the water and placed on the ground.

[0028] like Figure 4 As shown, a filter mechanism is provided between the detector body 1 and the interior of the bottom shell 2. The filter mechanism includes a filter screen 14.

[0030] Working principle: During detection, the remote control circulation pump 12 is started. After the circulation pump 12 is started, the water sample to be tested is sucked in from the bottom of the suction pipe 13, and then pumped into the water tank 2 11 through the drain pipe 16. As the water sample is sucked in, the water level continues to rise until the water level rises to the water tank 1 9 and is detected by the water quality sensor 10. At this time, the circulation pump 12 is turned off, and the water quality sensor 10 remotely transmits the detected water sample data to the external receiving end. After the detection is completed, the circulation pump 12 is reversed to reversely pump out the water in the water tank 1 9 and the water tank 2 11 and discharge it through the suction pipe 13.
