Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to a dissolved oxygen monitoring device capable of measuring different water layers. Background Art

[0002] Dissolved oxygen is one of the important indicators to measure the oxygen content in water. The dissolved oxygen level in water directly affects the biological ecosystem and water quality of the water. The dissolved oxygen level in high water layers usually indicates that the water quality is good and suitable for biological survival, while the dissolved oxygen level in low water layers may indicate that the water is polluted or hypoxic. Many organisms in the water, especially fish and other aquatic organisms, have a high demand for dissolved oxygen. The dissolved oxygen level in different water layers directly affects the survival and reproduction of aquatic organisms. By monitoring dissolved oxygen, the health of the biological ecosystem in the water body can be evaluated and possible ecological problems can be discovered in time. At present, dissolved oxygen monitors are mainly used to detect dissolved oxygen parameters in water layers. If dissolved oxygen parameters in water layers at different positions are to be detected, the position of the nozzle needs to be adjusted to extract water from different water layers. The operation of adjusting the position of the nozzle is difficult, and the probe of the dissolved oxygen monitor needs to be rinsed and cleaned with a flushing device before the detection of another water layer can be carried out. More small equipment needs to be used, and the connection between the equipment is not compact. The detection operation is incoherent and cumbersome, which needs to be improved. Therefore, we propose a dissolved oxygen monitoring device that can measure different water layers. Utility Model Content

[0021] In a specific embodiment of the utility model, the opening and closing of the solenoid valve 7 and the solenoid valve body 13 and the start and stop of the water pump 1 5 and the water pump 2 11 are controlled by a controller (not shown in the figure), and the controller can be integrated with the dissolved oxygen detection instrument 9 on a chassis. The dissolved oxygen detection instrument 9 includes a circuit board, a microprocessor and a power management system, a data storage device, and a display screen. The microprocessor is used to process the dissolved oxygen signal detected by the detection end 10 and convert it into a visual parameter for display on the display screen. The opening and closing control of each solenoid valve 7 is independently controlled by the controller, and the spacing between two vertically adjacent solenoid valves 7 can be adjusted according to the actual water layer. Customization can be performed, for example, the distance between two vertically adjacent solenoid valves 7 is set to 50 cm, the filter cover 701 can block large foreign objects to prevent clogging of the solenoid valve 7, and when the solenoid valve body 13 is opened, the water inside the detection tank 4 can be discharged into the water storage tank 2 for temporary storage. Vents are provided on the top surfaces of the detection tank 4 and the water storage tank 2 to ensure that the water inside the detection tank 4 can flow into the water storage tank 2 along the solenoid valve body 13. The lower tank body 401 and the upper tank body 402 are assembled in a split manner, which is conducive to the installation of the drain pipe 1101, the dissolved oxygen sensor 1001 and the adjustment of the water spraying position of the cleaning nozzle 1102.

[0022] In the preferred technical solution, the detection tank 4 and the detection tank 4 are both fixed on the surface of the pedestal 3. The bottom of the pedestal 3 is fixedly connected to the base 1 through a support. A water storage tank 2 is fixedly provided on the top surface of the base 1. The top of the water storage tank 2 is connected to the bottom of the detection tank 4. The support includes four columns of the same size. The four columns are distributed at four right angles on the top surface of the base 1. An electromagnetic valve body 13 is provided on the top of the water storage tank 2. The input end of the top of the electromagnetic valve body 13 is connected to the bottom of the detection tank 4. The water storage tank 2 is used to store waste liquid after detection and cleaning, and is discharged and treated in a centralized manner at a later stage.

[0023] In the preferred technical solution, the output port of the solenoid valve 7 is connected to the surface of the sampling tube 6 , and a filter screen 701 is provided outside the input port of the solenoid valve 7 , which can block large foreign objects and prevent the solenoid valve 7 from being blocked.

[0024] In the preferred technical solution, a support platform 8 is fixedly provided on one side surface of the upper tank body 402 , and a dissolved oxygen detection instrument 9 is fixed to the top surface of the support platform 8 by bolts, so that the support platform 8 is convenient for installing the dissolved oxygen detection instrument 9 .

The flange ring at the bottom of the upper tank body 402 is fastened to the flange ring at the top of the lower tank body 401 by bolts. The lower tank body 401 and the upper tank body 402 are assembled in a split manner, which is conducive to the installation of the drain pipe 1101, the dissolved oxygen sensor 1001 and the adjustment of the water spraying position of the cleaning nozzle 1102.

[0026] In the preferred technical solution, a weighted ball is fixedly provided at the bottom of the sampling tube 6. The weighted ball enables the sampling tube 6 to remain in a vertical state in the water, so that the position of the solenoid valve 7 in the water can be ensured to be stable.

[0027] Working principle: the solenoid valve 7 at a certain height is opened by the controller, and the water pump 15 is turned on. After the solenoid valve 7 is turned on, a negative pressure is generated at the input end to pump water, thereby pumping water into the upper tank body 402. When the liquid level reaches the detection standard, the water pump 15 and the solenoid valve 7 are closed. At this time, the dissolved oxygen sensor 1001 contacts the detection water and detects the dissolved oxygen parameters of the water layer at this height. After the detection is completed, the solenoid valve body 13 is opened to discharge the detected water, and the water pump 2 11 is turned on to pump the clean water inside the water storage tank 12 to the cleaning nozzle 1102 for spraying, thereby spraying and cleaning the dissolved oxygen sensor 1001 of the dissolved oxygen detection instrument 9. The detection parameters of the dissolved oxygen sensor 1001 after cleaning are reset to zero, and the waste liquid generated after cleaning flows from the solenoid valve body 13 into the water storage tank 2 for temporary storage. Finally, the water pump 2 11 and the solenoid valve body 13 are closed. The above steps can be repeated to monitor the dissolved oxygen in different water layers.
