Description

Technical Field

[0001] The utility model belongs to the technical field of water quality detection, in particular to a pipeline direct-insertion type water quality detection device. Background Art

[0002] The water supply network is a pipeline system that delivers and distributes water to users in a water supply project. It is composed of pipes, accessories and ancillary facilities. It is a municipal project that has a significant impact on people's lives. The water pressure in the water supply network will change during peak and trough water use, and during water supply-water cut-off-water supply. Therefore, the pressure detection and water quality detection of the network covers the entire life cycle of the water supply network and is also the top priority of the network control.

[0003] At present, the pressure detection technology of the pipe network is relatively mature, and generally an independent pressure detection instrument is used. However, water quality detection such as turbidity detection needs to rely on the overflow of the secondary water supply to the turbidity sensor equipment to be carried out. This is because the traditional turbidity sensor is designed and manufactured based on the principle of scattered light turbidity measurement. When a beam of light is shot into the water sample, the turbidity substances in the water sample scatter the light. By measuring the intensity of the scattered light in the direction perpendicular to the incident light and comparing it with the internal calibration value, the turbidity in the water sample is calculated, and the final value is output after linearization processing. In order to ensure the accuracy of the detection, high-definition transparent glass is required. This kind of glass directly installed on the turbidity detector is difficult to withstand the high pressure of the water supply network, resulting in the turbidity detector can only be used at the terminal of the pipe network, and it is impossible to cover the pipe network like the flow meter and pressure gauge. In addition, the more detection points there are, the more water is wasted. In order to carry out water quality detection, the water wasted by overflow of a single terminal detection device will reach more than 100 tons per year. Utility Model Content

[0010] Beneficial Effects

[0011] The utility model can be quickly installed on a pressurized pipeline, and can directly detect the water quality and pressure of the municipal pipeline network outdoors or at other locations to be inspected by directly inserting the pipeline, without stopping the water supply or modifying the existing pipeline network, and is also convenient for subsequent maintenance.

[0012] In addition, since the pipe is directly inserted, the utility model does not need to adopt overflow detection, which can achieve effective water saving. Compared with traditional equipment, it can save more than 100 tons of water per year.

[0013] The detection probe set of the utility model integrates various detectors such as water pressure, TDS, turbidity, temperature, etc., and is a multi-purpose machine. In view of the problem that the turbidity detector is difficult to withstand high pressure, the high-transmittance glass is physically sealed, which overcomes the problem that traditional probes cannot withstand high pressure and solves the risk of water immersion circuits.
