Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and more specifically, to a multifunctional real-time water quality monitoring device. Background Technology

[0002] Water quality monitoring is the main basis for water quality assessment and water pollution prevention and control. Therefore, it is of great significance to establish a real-time water quality monitoring and early warning system to provide data and information for water environment management and to obtain information on the distribution and changing trends of water pollution.

[0003] Traditional technologies for river water quality monitoring include manual laboratory monitoring and automated monitoring stations. Manual laboratory monitoring relies on the sampling frequency of laboratory personnel, is labor-intensive, has a delayed response time, and cannot reflect real-time changes in water quality. Furthermore, due to the unstable chemical properties of certain parameters, the sampling and delivery process can affect the test results, making this technology highly demanding to operate and sometimes only suitable for on-site testing.

[0004] Automatic monitoring stations are equipped with online water quality monitoring instruments that can reflect changes in water quality in real time. However, traditional water quality monitoring equipment is often bulky and expensive, and most of them can only monitor one or a few water quality parameters, making it difficult to comprehensively reflect the water quality situation.

[0005] On the other hand, traditional water quality testing equipment typically does not process air bubbles or flow rate in the water, which makes its testing accuracy susceptible to the influence of water flow and air bubbles, resulting in low accuracy.

[0006] Therefore, with the increasing requirements for environmental protection, there is a need for a miniaturized, low-cost device that is highly accurate and capable of real-time monitoring of multiple water quality indicators. Utility Model Content

[0035] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0036] Please see Figure 1 and combined Figure 2 , Figure 3 and Figure 5 As shown, the present invention provides a multifunctional real-time water quality monitoring device, comprising a box 10 with a hinged door 1, a flow stabilizing and defoaming tank 2 and a water quality sensor 4 installed inside the box 10, an inlet pipe 21 and an outlet pipe 22 connected to the flow stabilizing and defoaming tank 2 on the box 10, the water quality sensor 4 installed on the upper part of the flow stabilizing and defoaming tank 2 and extending into the flow stabilizing and defoaming tank 2, the water quality sensor 4 being connected to a signal processor 5 installed inside the box 10, and a water receiving tank 11 provided at the bottom of the box 10.

[0037] In use, the external water to be tested is introduced into the flow stabilizer and defoamer 3 through the inlet pipe 21 to defoam the water flow. The treated water then interacts with the water quality sensor 4 to quickly obtain the water quality parameters. The collected data is then sent to the signal processor 5 for processing and display. The water after testing can be discharged through the outlet pipe 22. The input and output power of the inlet pipe 21 and the outlet pipe 22 is provided by the water pump. The water quality sensor 4 includes a pH sensor 41, a residual chlorine sensor 42, a turbidity sensor 43, a conductivity sensor 44, and a temperature sensor 45. The water quality sensor 4 enables rapid detection of the pH, dissolved oxygen, turbidity, conductivity, and temperature of the water.

[0038] like Figure 1 As shown, the signal processor 5 is connected to an external terminal block, which is equipped with a temperature interface 51, a regulating valve interface 52, a flow meter interface 53, and a drain valve interface 54.

[0039] Furthermore, a standard liquid storage chamber 46 is also provided inside the box 10 of this utility model.

[0040] For a more detailed explanation of the technical solution of this invention, please refer to [link / reference needed]. Figure 4 As shown, the bottom of the defoaming tank of this utility model is provided with an inlet connected to the inlet pipe 21 and an outlet connected to the outlet pipe 22. A defoamer 3 is installed in the defoaming tank. The defoamer 3 includes a mounting frame 31 and defoaming cylinders 32 evenly arranged in the mounting frame 31. The mounting frame 31 is fixedly connected to the inner wall of the defoaming tank. There are multiple defoaming cylinders 32, which are arranged at intervals from bottom to top along the water flow direction. That is, along the water flow direction, the defoaming cylinders 32 in the same row have the same height. The water level of the defoaming cylinder 32 at the inlet end is lower than that of the defoaming cylinder 32 at the outlet end. The defoaming cylinder 32 has a conical structure that is smaller at the top and larger at the bottom. An exhaust pipe 33 is provided at the top of the defoaming cylinder 32. The bottom of the exhaust pipe 33 is pointed and the exhaust pipes 33 are spaced apart.

[0041] When water is introduced through the inlet, it moves from right to left. Under the action of buoyancy, the air bubbles in the water will automatically float to the defoaming cylinder 32. In order to improve the defoaming effect, the speed of the water flow should not be too high, so as to ensure that the air bubbles in the water flow can float quickly within a small range. After the air bubbles float, they first act on the end of the exhaust pipe 33 and puncture the air bubbles through the tip of the exhaust pipe 33. At the same time, the gas is discharged from the top. Preferably, an exhaust fan is connected to the top of the defoamer 3 to facilitate the rapid discharge of gas.

[0042] It is worth noting that the mounting frame 31 of this utility model has multiple water outlet holes on the bottom side near the water outlet, and the position of the water outlet holes is lower than that of the defoamer 3.

[0043] Furthermore, the bottom of the mounting frame 31 of this utility model is connected to the defoaming tank, and the water quality sensor 4 is set in the defoaming tank outside the mounting frame 31.

[0044] This utility model discloses a multifunctional real-time water quality monitoring device. The water to be tested is introduced through the water inlet pipe 21. In the flow stabilization and defoaming tank 2, the air bubbles in the flowing water are defoamed. The water flow rate is controlled to ensure that the water flow contacted by the water quality sensor 4 is close to the real flow, thereby reducing the influence of water flow rate and air bubbles on the detection results and improving the detection accuracy.

[0045] The water quality sensor 4 of this utility model includes a pH sensor 41, a residual chlorine sensor 42, a turbidity sensor 43, a conductivity sensor 44, and a temperature sensor 45. It integrates five sensors for pH, dissolved oxygen, turbidity, conductivity, and temperature, and can simultaneously monitor five key water quality parameters. The monitoring efficiency is improved, and the volume is reduced by 50% and the weight is reduced by 60%.

[0046] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
