Description

Technical Field

[0001] This utility model relates to the field of oil analyzer technology, specifically a water sample sampling structure and a shipborne ultraviolet oil analyzer containing the structure. Background Technology

[0002] The shipborne ultraviolet oil analyzer is a specialized device for real-time monitoring of oil pollution concentration in water bodies. It adopts the principle of ultraviolet fluorescence and achieves high-sensitivity detection by detecting the characteristic fluorescence produced by oil substances under ultraviolet light excitation. The instrument mainly consists of an ultraviolet light source, an optical detection system, a water sample collection unit, and a data processing module. It features small size, fast response, and strong anti-interference capabilities, making it particularly suitable for scenarios such as ship emission monitoring, port water quality inspection, and emergency response to marine oil spill accidents.

[0003] Currently, shipborne ultraviolet oil analyzers face severe challenges in marine environmental monitoring due to sampling contamination issues. In particular, the unavoidable cross-contamination during stratified sampling seriously affects the accuracy of the detection data. Although the multi-layer water sampler in traditional stratified sampling devices can collect water samples at different depths, it lacks an effective self-cleaning system during continuous sampling. This results in high-concentration oil residue in the upper layer contaminating the clean water sample in the lower layer. Especially when monitoring heavy crude oil leaks, the viscous oil will continue to contaminate the subsequent deep water samples.

[0004] Based on this, a water sample collection structure and a shipborne ultraviolet oil analyzer containing the structure are provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-7 As shown, a water sampling structure includes a sampling box 1, a sampling component is provided inside the sampling box 1, and a cleaning component is provided at the upper end of the sampling component; The cleaning assembly includes a water tank 14, which is fixedly connected to the upper part of the sampling box 1. A water pipe 10 is installed through the upper part of the water tank 14. A high-pressure pump 11 is fixedly connected to the middle of the water pipe 10. Several water distribution pipes 12 are fixedly connected to the output end of the high-pressure pump 11. A cleaning solenoid valve 13 is fixedly connected to the other end of each water distribution pipe 12. Each cleaning solenoid valve 13 is fixedly connected to an adjacent peristaltic pump 5 and each detection chamber 6. A filtering component is provided below the sampling component; In this embodiment, during use, the rotary motor 2 starts rotating the winding shaft 3, which uniformly places the sampling tube 4 into the water. The water level is monitored in real time by the pressure sensor 17. After reaching the designated water level, the sample at the corresponding water level is extracted. The sampled water enters the sampling tube 4 through the filter 15 and is filtered by the filter 15. Then, it is extracted by the peristaltic pump 5. At the same time, the sampling solenoid valve 8 on the corresponding detection chamber 6 is opened, allowing the sample to reach the designated detection chamber 6. At this time, the high-pressure pump 11 starts, and the cleaning solenoid valve 13 connected to the peristaltic pump 5 opens. The high-pressure pump 11 draws cleaning agent from the water tank 14 through the water pipe 10 and pours it into the water distribution pipe 12, which then quickly cleans the peristaltic pump 5 and the inside of the sampling tube 4, thus proceeding to the next extraction. The rotary motor 2 will continue to start, and the above steps will be repeated to sample the next water level. After the detection is completed, all the cleaning solenoid valves 13 will open together, and then clean together. Finally, the sample is flushed away by the peristaltic pump 5 and the sampling tube 4.

[0025] In one embodiment, such as Figure 2 As shown, the sampling assembly includes a peristaltic pump 5, and a plurality of sampling solenoid valves 8 are fixedly connected to the output end of the peristaltic pump 5. Each sampling solenoid valve 8 is fixedly connected to an inlet tube 7 at the other end, and each inlet tube 7 is fixedly connected to a detection chamber 6 at the other end. After reaching the designated water level, the sample at the corresponding water level is extracted. The sampled water enters the sampling tube 4 through the filter 15 and is filtered by the filter 15. Then, it is extracted by the peristaltic pump 5. At the same time, the sampling solenoid valve 8 on the corresponding detection chamber 6 is opened, so that the sample reaches the designated detection chamber 6.

[0026] In one embodiment, such as Figure 2 As shown, a winding component is provided below the sampling component to facilitate adjustment of the sampling depth.

[0027] In one embodiment, such as Figure 3 As shown, the winding assembly includes a winding shaft 3, which is rotatably positioned at the lower center of the sampling box 1. A sampling tube 4 is wound around the surface of the winding shaft 3. The inner wall of the sampling tube 4 is coated with an antibacterial coating to improve its anti-bioadhesion ability and extend the maintenance cycle. The upper end of the sampling tube 4 is fixedly connected to the input end of the peristaltic pump 5. A rotary motor 2 is fixedly connected to one side of the sampling box 1. The output end of the rotary motor 2 passes through one side of the sampling box 1 and is fixedly connected to one end of the winding shaft 3. The rotary motor 2 is a Masterflex peristaltic pump. Bidirectional suction can be achieved by rotating the motor in the opposite direction. When in use, the rotary motor 2 starts to rotate the winding shaft 3, and the sampling tube 4 is placed into the water at a uniform speed.

[0028] In one embodiment, such as Figure 3As shown, a fixing seat 9 is fixedly connected to one side of the sampling box 1. The fixing seat 9 is fixedly connected to one side of the adjacent sampling tube 4 to ensure that the sampling tube 4 can be wound up and will not be displaced on the winding shaft 3.

[0029] In one embodiment, such as Figure 5 As shown, the filtration assembly includes a sampling head 20, the upper end of which is fixedly connected to the lower end of the sampling tube 4. A filter 15 is fixedly connected to the lower end of the sampling head 20. The filter 15 is a Sartobran® P150 filter, which is resistant to high-pressure backwashing and can be sterilized. Counterweights 16 are fixedly connected to both sides of the sampling head 20, and a pressure sensor 17, model PTX5000, is fixedly connected to one side of the sampling head 20. The pressure sensor 17 monitors the water level in real time. After reaching the designated water level, the sample at the corresponding water level is extracted. The sampled water enters the sampling tube 4 through the filter 15 and is filtered by the filter 15.

[0030] In one embodiment, such as Figure 7 As shown, an oil analyzer body 18 is provided above the sampling box 1. The detection end of the oil analyzer body 18 is provided with a plurality of detection heads 19. Each detection head 19 penetrates the upper surface of the sampling box 1 and is disposed inside the adjacent detection chamber 6. The sample inside the detection chamber 6 is detected by the detection head 19.

[0031] In one embodiment, such as Figure 7 As shown, the oil analyzer body 18 is equipped with a detector and a controller. The detector and detection head 19 include a low-pressure mercury lamp, an LED ultraviolet light source, a photomultiplier tube, and a CCD spectrometer. High-sensitivity detection is achieved by detecting the characteristic fluorescence generated by oil substances under ultraviolet light excitation. The detector is electrically connected to each detection head 19. The controller is electrically connected to the sampling component, cleaning component, filtering component, winding component, and detector, respectively.

[0032] The above embodiments disclose a water sampling structure and a shipborne ultraviolet oil analyzer containing this structure. In use, the rotary motor 2 starts rotating the winding shaft 3, uniformly lowering the sampling tube 4 into the water. The water level is monitored in real time by the pressure sensor 17. After reaching the designated water level, the corresponding water level is sampled. The sampled water enters the sampling tube 4 through the filter 15 and is filtered. It is then drawn by the peristaltic pump 5. Simultaneously, the sampling solenoid valve 8 on the corresponding detection chamber 6 opens, allowing the sample to reach the designated level. Inside the testing chamber 6, the high-pressure pump 11 starts, and the cleaning solenoid valve 13 connected to the peristaltic pump 5 opens. The high-pressure pump 11 draws cleaning agent from the water tank 14 through the water pipe 10 and pours it into the water distribution pipe 12. Then, it quickly cleans the inside of the peristaltic pump 5 and the sampling tube 4, thus preparing for the next extraction. The rotary motor 2 will continue to start and sample the next water level according to the above steps. After the test is completed, all the cleaning solenoid valves 13 will open together and clean together. Finally, the solution is flushed away through the peristaltic pump 5 and the sampling tube 4.
