Description

Technical Field

[0001] The utility model relates to the technical field of water quality online monitoring equipment, in particular to a low-power consumption water quality online monitoring device applied to a municipal pipe network. Background Art

[0002] Municipal pipe network refers to the pipe system used to transport and discharge various liquids in the city, such as tap water, sewage, rainwater, etc. These pipe networks include water supply pipe network, sewage pipe network, rainwater drainage system, etc., which constitute an important part of urban infrastructure.

[0003] In the process of water quality monitoring for municipal pipe networks, low-power online water quality monitors are often needed. Low-power online water quality monitors are usually a device used to monitor various water quality parameters in water bodies in real time. It has the following characteristics:

[0004] Low power design: This type of monitoring instrument usually adopts a low power design to ensure long-term continuous monitoring without frequent battery replacement or charging. This is especially important for remote, unattended monitoring points.

[0005] Online monitoring: The monitoring instrument can continuously monitor various parameters in the water body in real time, such as pH value, dissolved oxygen concentration, turbidity, conductivity, temperature, etc., and provide accurate data.

[0006] Multi-parameter monitoring: In addition to single parameter monitoring, some low-power online water quality monitors can also monitor multiple water quality parameters at the same time, which helps to gain a more comprehensive understanding of the condition of the water body.

[0007] Remote data transmission: Monitoring instruments are usually equipped with remote data transmission function, which can transmit real-time monitoring data to the monitoring center or cloud platform, so that users can check and analyze water quality conditions at any time.

[0008] The existing low-power online water quality monitor uses a water pump to draw water from the municipal water network pipeline through a connecting pipe, and then injects water into the water tank provided in the online water quality monitor through a liquid inlet pipe, and then detects the water in the water tank through a variety of water quality monitoring sensors. After the detection is completed, the water is discharged from the liquid outlet pipe to complete the online monitoring of the water quality in the municipal pipe network. However, in the actual monitoring process, since the online water quality monitor needs to pump the water into the water tank through the water pump for monitoring, the water in the water tank will circulate for pumping and draining operations. During the long-term operation process, it is easy to cause the scale and dirt contained in the water to adhere to the tank wall. In the later stage of water intake, the dirt attached to the tank wall is easy to mix into the water body, which interferes with the water quality monitoring and measurement results, affecting the accuracy of the water body monitoring operation in the municipal pipe network.
