Description
Technical Field
[0001] This utility model relates to the field of water quality monitoring technology, specifically to a sampler for marine water quality monitoring. Background Technology
[0002] Marine water quality monitoring is a core component of marine ecological protection, marine resource development, and marine environmental management. Currently, commonly used marine water quality monitoring samplers mostly use transparent sampling tubes. However, in practical applications, whether for single sampling or long-term deployment, the outside of the sampling tube is easily covered by plankton, algae, and other organisms, affecting the observation effect of the transparent sampling tube. At the same time, for long-term deployed samplers, key functional parts such as sensors and water inlets are more susceptible to the adhesion of marine organisms such as algae and shellfish. After sampling, it is also necessary to manually clean the outer wall of the sampling tube, sensors, and water inlets, which is a rather cumbersome process. Therefore, there is an urgent need for a sampler for marine water quality monitoring. Utility Model Content

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] like Figures 1-7 As shown, this specific embodiment adopts the following technical solution: it includes a sampling tube 1 and a sealing cover 2. The sealing cover 2 is abutted at the upper opening of the sampling tube 1. A sealing ring 17 is fixedly installed in the annular groove at the bottom of the sealing cover 2. The bottom of the sealing ring 17 abuts against the sampling tube 1. The sealing ring 17 can improve the sealing performance of the gap between the sealing cover 2 and the sampling tube 1, and prevent water from seeping into the sampling tube 1 from the gap. It also includes: A connecting frame 3 is fixedly installed on the upper part of the sealing cover 2. A connecting rope 4 is fixedly installed on the connecting frame 3. A solenoid valve 5 is installed in each of the several water inlet holes opened on the sealing cover 2. A connecting shell 6 is fixedly installed at the bottom of the sealing cover 2. Power supply 7 is fixedly installed inside the connecting shell 6. A radio controller 8 electrically connected to the power supply 7 is fixedly installed inside the connecting shell 6. Water depth sensors 9 are fixedly installed in the groove opened on the upper part of the sealing cover 2. Water depth sensors 9 and solenoid valve 5 are electrically connected to the radio controller 8. There are two No. 1 connecting blocks 10, which are fixedly installed on the left and right sides of the sealing cover 2 respectively. No. 2 connecting blocks 11 are fixedly installed on the lower edges of the left and right sides of the sampling tube 1. A fixing rod 12 is fixedly installed on the No. 2 connecting block 11. There are two sleeve rods 13, which are movably sleeved on two fixed rods 12 respectively, and the upper end of the sleeve rod 13 is fixedly connected to the first connecting block 10. A cleaning ring 14 is movably sleeved on the sampling cylinder 1 and is fixedly set on the two sleeve rods 13. The upper part of the cleaning ring 14 is set with an outward downward inclined structure, which can provide a drop guide for the cleaned attachments and prevent the attachments from accumulating on the cleaning ring 14. Two reinforcing plates 18 are fixedly set on the upper part of the cleaning ring 14 and are fixedly connected to the sleeve rods 13. The reinforcing plates 18 can improve the structural strength of the connection between the cleaning ring 14 and the sleeve rods 13 to ensure the stability of the cleaning ring 14 in the cleaning process of the sampling cylinder 1. The sealing cover 2 is provided with a synchronous cleaning mechanism 15 and a limiting mechanism 16 that cooperates with the synchronous cleaning mechanism 15. The synchronous cleaning mechanism 15 includes: Cleaning rod 15-1 is movably abutted against the upper part of sealing cover 2. A first rotating rod 15-2 is fixedly inserted through the cleaning rod 15-1. The first rotating rod 15-2 is rotatably inserted into the sealing cover 2 through a bearing. A second rotating rod 15-3 is rotatably arranged inside the sealing cover 2 through a bearing. The lower end of the first rotating rod 15-2 is connected to the second rotating rod 15-3 through a bevel gear pair. The third rotating rod 15-4 is movably inserted into the fixed rod 12 on the left side. The upper end of the third rotating rod 15-4 is rotatably inserted into the first connecting block 10 on the left side through a bearing. The left end of the second rotating rod 15-3 is connected to the third rotating rod 15-4 through a bevel gear pair. Guide blocks 15-5, there are two guide blocks 15-5, which are respectively movably installed in the two spiral grooves 15-6 opened on the third rotating rod 15-4, and the guide blocks 15-5 are fixedly installed in the fixed rod 12. In the process of cleaning the outer ring wall of the sampling tube 1 by moving the cleaning ring 14 upward, the synchronous cleaning mechanism 15 can also realize the synchronous cleaning of the water inlet and various sensors 9 of water depth, effectively improving the cleaning efficiency. The limiting mechanism 16 includes: Limiting block 16-1, the limiting block 16-1 is sleeved on one end of cleaning rod 15-1, and the bottom of the limiting block 16-1 is fixedly provided with insertion rod 16-2, which is movably inserted into the slot 16-3 opened on the upper part of sealing cover 2; Spring 16-4 is fixedly installed in a rectangular groove on insert rod 16-2. Positioning block 16-5 is movably inserted in the rectangular groove and fixedly connected to one end of spring 16-4. Two positioning grooves 16-6 that cooperate with positioning block 16-5 are opened on the inner wall of slot 16-3.
[0021] When using this invention, the sampling tube 1 is submerged in the ocean using the connecting rope 4, and its depth is detected by various sensors 9. When it is necessary to sample water at the target depth, the solenoid valve 5 is opened to allow seawater to enter the sampling tube 1 through the inlet. After sampling, the solenoid valve 5 is closed to seal the inlet, and then the connecting rope 4 is pulled upwards to retrieve the sampling tube 1. When it is necessary to remove the water from the sampling tube 1, the limiting block 16-1 is pulled upwards to disengage it from the cleaning rod 15-1. The limiting block 16-1 also moves the insertion rod 16-2 upwards, causing the positioning block 16-5 to disengage from the lower positioning groove 16-6 and move into the rectangular groove, compressing the spring 16-4. When the positioning block 16-5 moves to the position corresponding to the upper positioning groove 16-6, the spring 16-4 returns to its original position and extends, pushing the positioning block 16-5 to abut against the upper positioning groove 16-6, thus achieving insertion in this state. Positioning of rod 16-2 and limit block 16-1 allows sealing cover 2 to be pulled upwards. Sealing cover 2 drives connecting block 10 and sleeve rod 13 to move upwards. Sleeve rod 13 drives cleaning ring 14 to move upwards, allowing cleaning ring 14 to scrape off the deposits on the outer ring wall of sampling cylinder 1. As rotating rod 15-4 moves upwards with connecting block 10, guide block 15-5 moves within spiral groove 15-6, causing rotating rod 15-4 to rotate. Rotating rod 15-4 drives rotating rod 15-3 through bevel gear pair. Rotating rod 15-3 drives rotating rod 15-2 through bevel gear pair. Rotating rod 15-2 drives cleaning rod 15-1 to rotate. When cleaning rod 15-1 rotates, it scrapes off the deposits on the inlet and the surface of various sensors 9. At this time, sealing cover 2 disengages from sampling cylinder 1, allowing the sampled water in sampling cylinder 1 to be poured out.
[0022] Compared with the prior art, the beneficial effects of this utility model are: When the sealing cover 2 is pulled, the sleeve rod 13 can drive the cleaning ring 14 to move upward and scrape off the attached material on the outer ring wall of the sampling tube 1. At the same time, with the cooperation of the synchronous cleaning mechanism 15, the attachments on the water inlet and water depth sensors 9 can be cleaned simultaneously without the need for separate cleaning steps, which greatly improves the cleaning efficiency. The sealing ring 17 can enhance the sealing performance between the sealing cover 2 and the sampling tube 1, preventing non-target seawater from seeping in. The solenoid valve 5 is installed at the inlet, which can close the inlet in time after sampling to prevent external impurities from mixing into the sampled water, effectively ensuring the purity of the sampled water and ensuring the accuracy of the monitoring data. The limiting mechanism 16 is easy to operate. Simply pull up the limiting block 16-1 to switch the limiting state of the cleaning rod 15-1. No additional tools are needed, which simplifies the operation process of lifting the sealing cover 2 and starting the cleaning component, and reduces the difficulty of manual operation. The upper part of the cleaning ring 14 adopts an outward downward tilting design, which can guide the scraped attachments to fall off smoothly and avoid accumulation that affects the cleaning effect.
[0023] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
