Description

Technical Field

[0001] This utility model belongs to the field of groundwater monitoring, specifically relating to a simple multi-parameter sensing device for groundwater monitoring in karst areas. Background Technology

[0002] Groundwater systems in karst areas are complex, and their distribution is highly variable due to dissolution. Existing monitoring equipment often only monitors a single parameter, such as water level or water quality, which is insufficient to meet the needs of multi-dimensional, real-time monitoring. Therefore, developing a simple device capable of simultaneously monitoring multiple parameters (such as water level, water quality, water temperature, water flow velocity, and vector flow direction) is of great significance.

Inside the sensing box, a water level sensing line, a water temperature sensing line, a Ph sensing line, a TDS sensing line, and a Do sensing line are sequentially arranged. These sensing lines are internally connected to a circuit integration terminal on the sensing box. Sensing probes are located at the bottom of each sensing line. The other end of the circuit integration terminal is connected to a display panel.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides, for example Figure 1-5The illustrated multi-parameter sensing device for groundwater monitoring in karst areas includes a sensor box 100. The sensor box 100 has an outlet 130 and an inlet 120 on its left and right sides, respectively, at the top of its bottom plate. Inside the sensor box 100, a water level sensing line 310, a water temperature sensing line 320, a Ph sensing line 330, a TDS sensing line 340, and a Do sensing line 350 are sequentially arranged. These sensing lines are internally connected to a wiring integration terminal 300 on the sensor box 100. Sensing probes are located at the bottom of each of the sensing lines. The other end of the wiring integration terminal 300 is connected to a display panel 400.

[0018] Five 10mm diameter sensing wires are designed inside the sensor box 100 for each of the following: water level sensing wire 310, water temperature sensing wire 320, Ph sensing wire 330, TDS sensing wire 340, and Do sensing wire 350. After passing through the insulation material 110, they are led out of the sensor box through the circuit integration terminal 300, avoiding the disadvantage of redundant circuits in traditional sensing wires. The sensor box 100 is placed in water, and the data is transmitted to the display panel 400 through the circuit integration of the sensor box 100 for real-time display of the required values. The display panel 400 can be powered by installing a battery.

[0019] In some specific embodiments of this utility model, a movable plate 140 is provided at the water outlet 130 and the water inlet 120. A water flow isolation plate 200 is provided at the upper end of the movable plate 140. A sliding groove 210 is provided at the lower part of the water flow isolation plate 200 and the upper part of the bottom plate of the sensor box 100 to match the movable plate 140. The left and right side plates of the sensor box 100 are provided with heat insulation material 110 inside the upper end of the water flow isolation plate 200. The front and rear side plates of the sensor box 100 are also provided with heat insulation material 110. The left and right side plates of the sensor box 100 and the movable plate 140 are respectively provided with connecting block 2 151 and connecting block 141 at the connection between them. Connecting block 141 matches the slot 150 provided on the left and right side plates of the sensor box 100. Connecting block 2 151 and connecting block 141 are magnetically connected.

[0020] When the sensor box 100 is placed in water, a water flow isolation plate 200 is installed to prevent water vapor evaporation and dampness from affecting the operation of the circuit integration line after the water flows into the sensor box 100. When water sample data is needed, the movable plates 140 at the inlet and outlet are opened at the same time. The movable plates 140 can be opened simply by moving them, ensuring that the water flow in the sensor box 100 is consistent with the water flow environment being tested. After the test is completed, the inlet 120 is closed by pushing the movable plate 140 to contact the connecting block 141 and the connecting block 2151. This is simple and convenient. The outlet 130 is kept open until there is no water flow in the sensor box, after which it is closed.

[0021] In some specific embodiments of this utility model, the sensor box 100 is provided with a corrosion-resistant material panel on the outside.

[0022] Ensure the continuous use of the sensor box 100 in different water environments.

[0023] In some specific embodiments of this utility model, the thermal insulation material 110 is polystyrene foam to prevent external factors from affecting the accurate measurement of values, and the water flow barrier 200 is thermoplastic polyolefin material, which has better waterproof performance.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
