Description

Technical Field

[0001] This utility model relates to the field of seawater quality sampling, specifically a seawater quality sampling device for marine monitoring. Background Technology

[0002] As is well known, water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends, and evaluating the water quality status. The monitoring scope is very broad, including unpolluted and polluted natural water (rivers, lakes, seas, and groundwater) as well as various industrial wastewater. Among them, marine water quality testing is an important part of water quality testing. Usually, the testing personnel travel with the ship to the sea area to be tested and then take random samples.

[0003] In practical use, existing sampling devices place the entire sampling box in seawater, allowing it to fall downwards under its own weight to collect samples. However, since marine debris is collected along with the sampling box during the sampling process, some of this debris can clog the sampling tube when seawater is poured into the box through the sampling tube, thus affecting the seawater sampling work. Furthermore, it is inconvenient for staff to clean the sampling box afterward, increasing their workload, and internal impurities can cause inaccurate detection.

[0004] In summary, during actual use, the above-mentioned structure can clog the sampling tube with marine debris, thus affecting seawater sampling. Furthermore, it makes it inconvenient for staff to clean the sampling box afterward, increasing their workload. In addition, internal impurities can cause inaccurate detection. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a seawater quality sampling device for marine monitoring, so as to solve the technical problems that marine debris will clog the sampling tube, thereby affecting the seawater sampling work, and making it inconvenient for staff to clean the sampling box afterward, increasing the workload of staff, and that internal impurities will cause inaccurate detection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seawater quality sampling device for marine monitoring, comprising a housing, a filter plate slidably disposed inside the housing, and an array of filter holes disposed on the filter plate, a float plate slidably disposed at the bottom of the filter plate, an array of guide posts cooperating with the filter plate evenly disposed at the top of the float plate, and the top ends of the guide posts being arc-shaped, and a sampling tube penetrating through the bottom of the float plate on the outer wall of the housing, and a control switch disposed on the sampling tube.

[0007] By adopting the above technical solution, impurities in seawater are filtered through the filter plate. This process ensures that no marine impurities are present in the seawater that subsequently passes through the sampling tube, further improving the overall accuracy of seawater quality testing. When seawater enters the tank, the bottom float plate floats upward. At this time, the guide post at the top of the float plate inserts into the filter holes of the filter plate to clean the filter plate and ensure that marine debris is uniformly placed on top of the filter plate, reducing the cleaning burden on subsequent staff.

[0008] The present invention is further configured such that the inner wall of the box is symmetrically provided with sliding grooves, and limiting blocks that cooperate with the sliding grooves are provided on both sides of the filter plate.

[0009] Preferably, the filter plate is positioned at different heights within the housing by the cooperation of the sliding groove and the limiting block, and the height of the filter plate can be adjusted by the staff according to the actual situation, thereby realizing quantitative sampling of seawater and further improving the overall practicality of the device.

[0010] The present invention is further configured such that sliders are symmetrically arranged on both sides of the float plate, and the sliders are arranged in a smooth manner between the outer wall of the sliders and the groove.

[0011] Preferably, the chute and the slider work together to allow the float to slide vertically within the box. The smooth surface between them effectively reduces the friction between the chute and the slider, enabling the float to slide stably upwards.

[0012] The present invention is further configured such that the top of the float plate is arc-shaped and there is a gap between the float plate and the inner wall of the box.

[0013] Preferably, the arc shape allows the seawater to slide to both sides as it slides down the filter plate, and the gap between the two allows the seawater to flow to the bottom of the tank, preventing the seawater from staying on the top of the float plate.

[0014] The present invention is further provided that the two sides of the box are symmetrically provided with handles, and the outer wall of the handle is roughened.

[0015] Preferably, the handle facilitates the directional movement of the box by the testing personnel, which further improves the overall practicality of the device. In addition, the rough texture effectively increases the sliding friction between the operator's hand and the handle.

[0016] The present invention is further provided that the outer wall of the box is provided with an observation window at the top of the sampling tube.

[0017] Preferably, the observation window allows staff to directly observe the water quality inside the tank, effectively preventing impurities from being introduced during the sampling process.

[0018] The present invention is further configured such that the overall height of the guide post is the same as the depth of the filter holes on the filter plate.

[0019] Preferably, when the guide post is inserted into the filter hole of the filter plate, the filter plate and the guide post are at the same horizontal height. This makes it easier for the staff to clean the impurities discharged from the filter hole, further reducing the cleaning burden on the staff.

[0020] The present invention is further configured such that a limiting mechanism is provided between the limiting block and the slide groove.

[0021] Preferably, by setting a limiting mechanism, the limiting block can be fixed at a designated position in the slide during the movement of the limiting block.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention incorporates a filter plate and a float plate within the tank. When the tank is placed in seawater, the filter plate filters impurities, ensuring that the seawater passing through the sampling tube is free of marine debris. This significantly improves the overall accuracy of seawater quality testing. Furthermore, as seawater enters the tank, the float plate at the bottom floats upwards. At this time, the guide post at the top of the float plate inserts into the filter holes of the filter plate, cleaning it and ensuring that marine debris is uniformly placed on top of the filter plate, reducing the cleaning burden on subsequent personnel.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] First embodiment:

[0033] Please see Figure 1-4 The figure shows a seawater quality sampling device for marine monitoring, comprising a housing 1, a sampling tube 2, a sliding mechanism, a filtering mechanism, and a sealing mechanism. Handles 6 are symmetrically arranged on both sides of the housing 1, with a rough outer wall. The handles 6 facilitate directional movement of the housing 1 by the testing personnel, further improving the overall practicality of the device. The rough surface also effectively increases the sliding friction between the operator's hand and the handles 6. Seawater then flows into the housing 1 under its own weight. A filter plate 5 is slidably installed inside the housing 1, with multiple filter holes. The filter plate 5 filters impurities from the seawater, ensuring that the seawater passing through the sampling tube 2 is free of marine impurities, thus further improving the overall accuracy of seawater quality testing. Furthermore, a float plate 8 is slidably installed at the bottom of the filter plate 5, and an array of guide posts 7 that cooperate with the filter plate 5 are evenly arranged at the top of the float plate 8. The top of the guide posts 7 is arc-shaped. When seawater enters the tank 1, the bottom float plate 8 floats upward. At this time, the guide posts 7 at the top of the float plate 8 will insert into the filter holes of the filter plate 5 to clean the filter plate 5 and keep marine debris at the top of the filter plate 5, reducing the cleaning burden for subsequent staff. An observation window 3 is set at the top of the sampling tube 2 on the outer wall of the tank 1. The observation window 3 allows staff to directly observe the water quality of the seawater in the tank 1, effectively preventing impurities from being mixed in during the sampling process. At the same time, a sampling tube 2 is installed through the bottom of the float plate 8 on the outer wall of the tank 1, and a control switch is set on the sampling tube 2. The seawater in the tank 1 is sampled under the action of the sampling tube 2.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 2Slider blocks 10 are symmetrically arranged on both sides of the float plate 8, and the outer wall of the slider 10 and the groove 9 are smoothly arranged. With the cooperation of the groove 9 and the slider 10, the float plate 8 slides vertically in the box 1. The smooth arrangement between the two effectively reduces the friction between the groove 9 and the slider 10, allowing the float plate 8 to slide stably upward. The top of the float plate 8 is arc-shaped, and there is a gap between the float plate 8 and the inner wall of the box 1. The arc shape allows the seawater to slide to both sides when it slides down through the filter plate 5, and the gap between the two allows the seawater to flow to the bottom of the box 1, preventing the seawater from staying on the top of the float plate 8.

[0035] Second embodiment:

[0036] Please see Figure 2 The illustrated seawater quality sampling device for marine monitoring has an overall structure similar to that of Embodiment 1. The inner wall of the housing 1 is symmetrically provided with sliding grooves 9, and limiting blocks 4 that cooperate with the sliding grooves 9 are located on both sides of the filter plate 5. A limiting mechanism is provided between the limiting blocks 4 and the sliding grooves 9. Through the setting of the limiting mechanism, the limiting blocks 4 can be fixed at a designated position in the sliding grooves 9 during movement. The cooperation between the sliding grooves 9 and the limiting blocks 4 allows the filter plate 5 to be positioned at different heights within the housing 1, and the operator can adjust the height of the filter plate 5 according to the actual situation, thereby achieving quantitative sampling of seawater and further improving the overall practicality of the device.

[0037] In practical operation, this invention works as follows: The entire housing 1 is placed in the seawater to be tested. Under its own weight, the housing 1 sinks into the seawater, allowing seawater to flow into it. Because a filter plate 5 is installed inside the housing 1, the seawater is filtered, ensuring that marine debris is located at the top of the filter plate 5. This effectively prevents clogging of the sampling tube 2 when the seawater is poured out for sampling, further improving the accuracy of seawater testing. Simultaneously, a float plate 8 is slidably installed at the bottom of the filter plate 5. As seawater flows in, the float plate 8 floats upwards, and the guide post 7 at the top of the float plate 8 cleans the filter holes of the filter plate 5, ensuring that marine debris is uniformly located at the top of the filter plate 5, reducing the cleaning burden on subsequent personnel.
