[0001] The utility model relates to the technical field of water quality sampling devices, and particularly relates to an industrial water quality sampling device for environmental protection detection. Background Technique

[0002] Water quality detection is to evaluate the quality status of water bodies and ensure the safety and suitability of water resources. It is crucial for protecting public health and safety, maintaining ecological balance, and guiding the rational utilization and protection of water resources. Before detection, sampling devices are needed to sample water quality in various places.

[0003] Currently, in general, staff tie a rope to a sampling bottle and then directly put it into the sampling location for sampling. This method cannot control the sampling depth and cannot sample the water quality at different depths in the same water area, resulting in non-standard detection results of the sampled water and affecting the detection effect. To solve the above technical problems, we have designed an industrial water quality sampling device for environmental protection detection. Content of the Utility Model

[0020] Please refer to Figures 1 - 4 , an industrial water quality sampling device for environmental protection detection, including a sampling tube 1. A threaded joint 11 is connected to the bottom of the sampling tube 1. Liquid level sensors 5 are fixedly installed at the top of the left and right sides of the sampling tube 1. The detection ends of the liquid level sensors 5 are located inside the sampling tube 1 and are used to detect the water level inside the sampling tube 1, facilitating the staff to observe the water volume inside the sampling tube 1 from above the water. Infrared distance sensors 12 are fixedly installed at the front and rear sides of the top of the sampling tube 1. A fixed rope 10 is fixedly installed at the center of the top of the sampling tube 1. A floating assembly 6 is sleeved on the surface of the fixed rope 10. The floating assembly 6 includes a floating plate 61. A controller 8 and a power supply 9 are respectively fixedly installed at the front and rear sides of the top of the floating plate 61. By setting the power supply 9, the electrical equipment of the device can be powered, enabling it to be carried out for use without connecting wires. Air extraction assemblies 7 are fixedly installed at the left and right sides of the top of the floating plate 61. The air extraction assemblies 7 include air extraction pumps 71;

[0021] Please refer to Figure 1 and Figure 2 , a connecting pipe 3 is threadedly connected to the inner cavity of the threaded joint 11. A filter residue ball 4 is sleeved on the bottom surface of the connecting pipe 3. The filter residue ball 4 is of a hollow structure. By setting the hollow structure of the filter residue ball 4, large impurities in the water can be filtered, and at the same time, it will not prevent the water liquid from entering the inside of the connecting pipe 3;

[0022] Please refer to Figure 1 and Figure 3 , a through hole for the fixed rope 10 to pass through is provided through the center of the floating plate 61. A fixed cylinder 62 is fixedly connected to the top of the floating plate 61 and located outside the through hole. A connecting screw cylinder 63 is fixedly connected to the front side of the fixed cylinder 62;

[0023] Please refer to Figure 3 , a fastening bolt 64 is threadedly connected to the inner cavity of the connecting screw cylinder 63. One end of the fastening bolt 64 extends into the inner cavity of the fixed cylinder 62 and is in close contact with the surface of the fixed rope 10. The inner diameter of the fixed cylinder 62 is 5 mm - 10 mm larger than the diameter of the fixed rope 10. The fixed cylinder 62 is a certain distance larger than the fixed rope 10, which can facilitate the fixed cylinder 62 to adjust its position on the surface of the fixed rope 10 at will, facilitating the staff to adjust it to different positions for sampling;

[0024] Please refer toFigure 1 and Figure 4 The intake end of the air extraction pump 71 is connected with a hose 72. By providing the hose 72, when the floating plate 61 moves, the air extraction pump 71 can always be connected to the sampling pipe 1, ensuring that the air extraction pump 71 can extract air from the sampling pipe 1 at any time. The bottom of the hose 72 penetrates through the floating plate 61 and is connected to the top of the outer surface of the sampling pipe 1;

[0025] Please refer to Figure 4 , the hose 72 is arranged in a coiled pipe structure. A fixing seat is fixedly installed at the bottom of the air extraction pump 71, and the fixing seat is fixedly installed on the top of the floating plate 61;

[0026] Please refer to Figure 1 and Figure 2 , a counterweight 2 is fixedly sleeved on the bottom surface of the sampling pipe 1. By providing the counterweight 2, the sampling pipe 1 can be weighted, enabling it to quickly sink underwater and improving the sampling speed. A fixing ring is fixedly installed at the top of the sampling pipe 1, and the fixing rope 10 is tied and fixed in the inner cavity of the fixing ring.

[0027] During use, straighten the fixing rope 10, loosen the fastening bolt 64 so that it disengages from the fixing rope 10, then move the floating plate 61 to drive the fixing cylinder 62 to move on the surface of the fixing rope 10. Detect the distance between the sampling cylinder 1 and the bottom of the floating plate 61 through the infrared distance measuring sensor 12. After it reaches the required length, tighten the fastening bolt 64. Under the action of the thread of the connecting screw cylinder 63, drive the fastening bolt 64 to move until the fastening bolt 64 is in close contact with the surface of the fixing rope 10, so that it presses the fixing rope 10 against the inner wall of the fixing cylinder 62, thereby fixing the fixing cylinder 62 and the floating plate 61 at the designated position on the fixing rope 10. Then hold the fixing rope 10 and put the device into the water area at the designated position. Under the action of the gravity of the counterweight 2, drive the sampling pipe 1 to sink until the fixing rope 10 is completely straightened. At this time, the floating plate 61 floats on the water surface due to the buoyancy force. Then start the air extraction pump 71 to extract the gas inside the sampling pipe 1 from the hose 72, reducing the air pressure inside the sampling pipe 1, so that water can sequentially flush through the filter slag ball 4, the connecting pipe 3, and the threaded joint 11 into the sampling pipe 1. During the sinking process of the sampling pipe 1, the internal air pressure remains unchanged and external water will not enter the sampling pipe. The large impurities in the water are filtered through the filter screen on the surface of the filter slag ball 4 to avoid blockage. The liquid level sensor 5 detects the water level depth inside the sampling pipe 1 and sends the information back to the staff terminal for the staff to view. When the sampling water level inside the sampling pipe 1 reaches the required amount, stop the air extraction pump 71, and then the staff can pull the device out of the water through the fixing rope 10.

[0028] In summary, the industrial water quality sampling device for environmental protection testing solves the problems of inability to control the sampling depth and inability to sample the water quality at different depths in the same water area through the cooperation of the sampling pipe 1, the counterweight 2, the liquid level sensor 5, the floating assembly 6, the air extraction assembly 7, the fixing rope 10, and the infrared ranging sensor 12. This can lead to non-standard test results of the sampled water and affect the time detection effect.
