Description

Technical Field

[0001] The utility model belongs to the technical field of water quality monitoring equipment, and in particular relates to an underground water quality monitoring device. Background Art

[0002] Water quality monitoring equipment is used to detect and evaluate the quality of water bodies to ensure that the water quality meets specific environmental standards and health requirements. With the increase of national environmental awareness, it is becoming more and more important to test water quality. In order to understand the water quality of rivers in real time, water quality monitoring stations will be established in key rivers and lakes to monitor the quality of water environment and its pollution changes at any time, providing important information for the protection, management and prevention of water pollution. When monitoring water quality, it is generally necessary to put the sampling equipment into the water, extract water samples into the equipment, and then test the samples through water quality monitoring equipment. However, the sampled water bodies are often accompanied by sludge, water plants, duckweed or various domestic garbage in the river. These impurities will affect the detection accuracy of the monitor, and long-term use of these impurities will adhere to the surface of the detection sensor, and the equipment needs to be cleaned frequently, which not only wastes a lot of energy, but also causes monitoring deviations if the cleaning is not timely, thus affecting the monitoring results.

[0045] A water pump 11 is provided in the sampling box 1, and a water intake pipe 4 is provided on the top of the sampling box 1. One end of the water intake pipe 4 extends into the sampling box 1 and is connected to the water pump 11, and the other end of the water intake pipe 4 extends into the river water.

[0046] One end of the water intake pipe 4 close to the sampling box 1 is movably connected to a first filter assembly 5;

[0047] The first filter assembly 5 comprises a filter cartridge 51, in which a filter element 52 is arranged. The filter element 52 is made of volcanic rock or quicksand, and performs a primary filtration on weeds and silt in the river water.

[0048] The sampling box 1 is provided with a second filter assembly 6, and the second filter assembly 61 includes a first filter plate 61, a second filter plate 62 and a third filter plate 63. The first filter plate 61, the second filter plate 62 and the third filter plate 63 are sequentially arranged and fixed on the inner wall of the sampling box 1 from top to bottom to further filter the sediment in the river water sample to ensure that the water sample finally entering the monitoring box 2 does not contain sediment;

After the filtration is completed, the nozzle 64 cleans the second filter component 6, and the cleaned soil can be removed from the sampling box 1.

[0051] Through the above technical solution, the water pump 11 is started to extract water samples from the river. When the water sample flows through the first filter component 5, the weeds and sediment in the river water are first filtered through the filter element 52. The filter element 52 is volcanic rock or quicksand, which has a fast filtering speed and a good filtering effect on seaweed and sediment. After entering the sampling box 1, it passes through the first filter plate 61, the second filter plate 62 and the third filter plate 63. The sample finally enters the monitoring box 2 without sediment.

[0054] One end of the water intake pipe 4 connected to the sampling box 1 is arranged on the left side of the top of the sampling box 1;

[0055] The nozzle 64 is arranged on the left side of the top of the sampling box 1 .

[0056] Preferably, arc grooves are provided on the first filter plate 61 , the second filter plate 62 and the third filter plate 63 .

[0057] Preferably, a baffle 65 is rotatably provided in the sampling box 1, and the baffle 65 is provided below the third filter plate 63.

When sampling is performed, the baffle 65 is rotated downward and opened, and the filtered water flows down through the baffle 65 and enters the monitoring box 2; when the nozzle 64 cleans the second filter assembly 6, the baffle 65 is rotated upward to prevent the cleaned water with sludge from flowing into the monitoring box 2.

[0058] Preferably, a slide groove 14 is provided on the inner wall of the sliding door 12, a slider 15 is slidably provided in the slide groove 14, the slider 15 is rotatably connected to a rotating rod 16, and the other end of the rotating rod 16 is fixedly connected to a baffle 65. When the sliding door 12 is opened, the slider 15 drives the rotating rod 16 to rotate, and the rotating rod 16 pulls the baffle 65 to rotate upward to block the liquid flow between the sampling box 1 and the monitoring box 2. When the sliding door 12 is closed, the slider 15 pushes the rotating rod 16 to move downward, and the baffle 65 rotates downward to open the flow channel between the sampling box 1 and the monitoring box 2.

[0059] Preferably, a drying component 7 is provided between the sampling box 1 and the monitoring box 2, and the drying component 7 includes a bellows 71, an air inlet pipe 72 and an air outlet pipe 73, and the two ends of the air inlet pipe 73 are respectively connected to the bellows 71 and the sampling box 1; the two ends of the air outlet pipe 73 are respectively connected to the bellows 71 and the monitoring box 2; and a hot air blower 74 is provided in the bellows 71.

[0060] By providing the drying component 7, after the second filter component 6 is cleaned, the sampling box 1 and the monitoring box 2 are dried, so as to better improve the service life of the equipment and the detection accuracy for the next use.

[0061] Preferably, threads are provided at both ends of the filter cartridge 51 , and the water intake pipe 4 is threadedly connected to the filter cartridge 51 via a nut 53 .

[0062] The working principle of the utility model is as follows: the water pump 11 draws river water into the sampling box 1. The river water flows through the water intake pipe 4 and first passes through the first filter component 5. The filter element 52 is volcanic rock or quicksand, which can quickly perform the first step of filtering the river water, and preliminarily filter the aquatic plants, duckweed and mud in the water. Then, the water enters the sampling box 1 and flows through the first filter plate 61, the second filter plate 62 and the third filter plate 63 in turn. Multiple filtration ensures that the mud and sand are filtered cleanly. The filtered river water flows into the bottom of the sampling box 1 through the tilted open baffle 65, and enters the monitoring box 2 through the first pipe 3 to monitor the water quality.

[0063] After the monitoring is completed, the filter cartridge 51 can be disassembled and the filter element 52 can be cleaned, because the filter element 52 is volcanic rock or quicksand, which can be cleaned and reused, which is green and environmentally friendly. Then open the sliding door 12 on one side of the sampling box 1. When the sliding door 12 is opened, the slider 15 drives the rotating rod 16 to move, thereby driving the baffle 65 to rotate upward to block the connection between the sampling box 1 and the monitoring box 2. The second filter component 6 is cleaned through the nozzle 64, and the cleaned mud and sand flow out along the opened sliding door 12 to avoid the presence of mud and sand in the sampling box 1 affecting the monitoring results. After cleaning, close the sliding door 12, start the hot air blower 74, and dry the sampling tube 1 and the monitoring box 2 to avoid the residual sample affecting the next monitoring result.

[0064] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
