Description

Technical Field

[0001] The utility model relates to the technical field of hydrological detection, in particular to a hydrological and water quality detection device. Background Art

[0002] Hydrology is a crucial foundation for water conservancy work. As water conservancy efforts shift from developing water conservancy projects and eliminating flood hazards to addressing shortcomings and strengthening oversight, this requires more hydrological testing and monitoring technologies, gradually establishing comprehensive, rationally arranged hydrological monitoring stations that cover a wide range of indicators, including water level, flow, rainfall, water quality, groundwater, evaporation, and sediment. Water quality testing is crucial for comprehensive hydrological monitoring. Key testing items can be divided into two categories: one encompasses comprehensive indicators reflecting water quality, such as temperature, color, turbidity, pH, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand (COD), and biochemical oxygen demand (BOD); the other encompasses toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury, and organic pesticides. Currently, semi-quantitative test strips are often used to test water quality at a specific location. However, these strips react before reaching the bottom of the water, making their results unreliable. Furthermore, rapid underwater flow easily breaks through the semi-quantitative test strips, rendering the testing process unreliable. Utility Model Content

The entire hydrological and water quality testing device mainly includes water quality testing components, which detect various indicators of water quality conditions.

[0005] Preferably, multiple marking strips representing different colors are sequentially arranged on the left side of the sealing structure from top to bottom. The visual inspection module includes an optical inspection unit facing the left side of the sealing structure, and the optical inspection unit is configured to detect the displacement of the multiple marking strips. The optical inspection unit can more easily and reliably detect the movement of the multiple marking strips representing different colors, thereby improving the reliability of displacement detection and confirming whether the entire sealing structure has been opened.

[0006] Preferably, the visual inspection module further includes a processing unit electrically connected to the optical inspection unit, the processing unit configured to determine whether the displacement exceeds a preset value and, if so, generate and issue a detection signal. The processing unit determines whether the displacement exceeds the preset value. If so, indicating that the entire inspection chamber is fully opened and the test strip is fully reacting, the processing unit generates and issues a detection signal, allowing the user to obtain information on the progress of the entire inspection process.

[0007] Preferably, the detection chamber further comprises a plurality of enclosures, which are sequentially connected and integrally arranged to enclose the detection chamber. The enclosures can block vertical water flow to a certain extent, provide a certain degree of protection to the test strip during the entire process of the underwater detection mechanism entering the water and during the process of the sealing structure moving upward, and the enclosures can reliably fix the test strip.

[0008] Preferably, the sealing structure includes a sealing cover, which is arranged around the detection chamber, and the pushing legs and the limiting guide structure are arranged on the side of the sealing cover. The sealing cover can completely cover the detection chamber, and if multiple detection chambers are provided, it can cover all the detection chambers at the same time.

[0009] Preferably, the limiting guide structure includes a clamping head and a connecting rod connecting the clamping head. The connecting rod is fixed to the side of the sealing cover. The clamping head has a slot on the side, and the edge of the first mounting bracket is engaged with the slot. The clamping strip engages with the edge of the first mounting bracket through the slot, and the edge of the first mounting bracket slides up and down along the slot, representing the up and down sliding of the sealing structure.

[0010] Preferably, a hanging block is fixed on the left side of the first mounting frame, a fixed end is provided on the top of the hanging block, and the fixed end is connected to the traction mechanism.

[0011] Preferably, the system further comprises a hydrological processing module, the hydrological processing module being electrically connected to a remote processing terminal and communicating with the processing unit, and the hydrological processing module being used to process the hydrological comprehensive detection data.

[0014] The beneficial effects of the present invention are as follows:

[0015] In the present invention, the height of the underwater detection mechanism is adjusted by the traction mechanism, and the underwater detection mechanism can quickly complete the water-out and water-in operations. After the underwater detection mechanism enters the water, the sealing structure, the pushing legs and the limit guide structure are a whole. Since the gravity of the whole is much greater than the buoyancy, in the absence of other external forces, the bottom surface of the sealing structure is always in contact with the top surface of the second mounting bracket, and the external liquid will not fully flow into the detection chamber, and the test strip will not react on a large scale. When the underwater detection mechanism falls to the bottom of the water, reef or other solid object surface, the pushing legs are acted upon by external force, and the first mounting bracket, the second mounting bracket and the detection chamber continue to move downward. At this time, the detection chamber will be directly opened, and the test strip will directly contact the external water body, and then start to react. Since the left and right sides of the test strip can both contact with the outside water body, The underwater detection mechanism is brought into contact with the surface, thereby greatly improving the reaction speed and reaction area. Therefore, the detection process is completed in a very short time, and the traction mechanism can take out the underwater detection mechanism, and then complete the judgment of the test strip; further, the limiting guide structure can ensure that the sealing structure moves up and down along a fixed direction, thereby improving the reliability of opening the detection chamber; further, the displacement of the sealing structure is detected by the visual detection module, thereby confirming whether the entire sealing structure is opened, and completing the reliable judgment of the detection process; further, the right side of the detection chamber is blocked by the baffle, and the left side of the detection chamber is blocked by the vertically extending first mounting bracket, so that high-speed flowing water is not allowed to form a flow channel in the detection chamber, thereby avoiding continuous impact on the test strip, and ensuring the test reliability and test effect as much as possible.

After the underwater detection mechanism 12 enters the water, the sealing structure 124, the pushing legs 125 and the limiting guide structure 126 are a whole. Since the gravity of the whole is much greater than the buoyancy, in the absence of other external forces, the bottom surface of the sealing structure 124 is always in contact with the top surface of the second mounting frame 122, and the external liquid will not fully flow into the detection cavity 1231, and the test strip 1233 will not react on a large scale.

At this time, the detection chamber 123 will be directly opened, and the test strip 1233 will directly contact the external water body, and then start to react. Since the left and right sides of the test strip 1233 can The underwater detection mechanism 12 is contacted with the outside world, thereby greatly improving the reaction speed and reaction area, so that the detection process is completed in a very short time, and the traction mechanism can take out the underwater detection mechanism 12, and then complete the judgment of the test strip 1233; further, the limiting guide structure 126 can ensure that the sealing structure 124 moves up and down along a fixed direction, thereby improving the reliability of opening the detection chamber 123; further, the displacement of the sealing structure 124 is detected by the visual detection module 127, thereby confirming whether the entire sealing structure 124 is opened, and completing the reliable judgment of the detection process; further, the right side of the detection chamber 1231 is blocked by the baffle 1232, and the left side of the detection chamber 1231 is blocked by the vertically extending first mounting frame 121, so that high-speed flowing water is not allowed to form a flow channel in the detection chamber 1231, thereby avoiding the test strip 1233 from being subjected to continuous impact, and ensuring the test reliability and test effect as much as possible.
