Description

Technical Field

[0001] This invention relates to the field of observation equipment technology, specifically to a marine equipment seawater extraction and observation device. Background Technology

[0002] Seawater sampling and observation are primarily conducted to obtain accurate, targeted water samples for analysis. Because seawater is a dynamic mixture, its temperature, salinity, chemical composition, and the distribution of substances such as plankton and pollutants are not uniform and vary with depth, location, and time. Direct, comprehensive measurements over vast ocean areas are extremely difficult. By sampling water at different locations and depths, scientists can obtain detailed information about specific water layers, much like "slicing a piece of the surface." These samples, once brought back to the laboratory, can undergo more precise analysis for monitoring marine environmental health, studying marine ecosystems, tracking pollutant dispersion, understanding the impacts of climate change on the ocean, and even exploring seabed resources. It is an indispensable foundational tool for marine scientific research and environmental protection.

[0003] Existing seawater extraction and observation equipment suffers from several significant shortcomings in practical applications: First, most devices have fixed or inconveniently adjustable sampling depths, making it difficult to accurately obtain samples from different water layers and limiting the three-dimensionality and representativeness of the observation data. Second, seawater adheres to the surface of the sampling tube during retrieval; these saline droplets, once inside the equipment, easily corrode metal parts and electrical components, severely impacting the equipment's lifespan and reliability. Furthermore, the sample containers of traditional equipment are typically cumbersome to install and remove, especially in turbulent environments such as ship cabins, leading to low efficiency and a high risk of spillage. Simultaneously, the sampling head lacks effective pretreatment filtration during extraction, allowing impurities in the water to clog the pipes, affecting sampling continuity and increasing maintenance frequency. These shortcomings collectively restrict the efficiency and data quality of marine observation operations. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a marine equipment seawater extraction and observation device. This device solves the problems of fixed or inconvenient sampling depth and the fact that seawater adheres to the surface of the sampling tube during the recovery process. These saline water droplets can easily corrode metal parts and electrical components, seriously affecting the lifespan and reliability of the equipment.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example: like Figure 1-6 As shown, this embodiment of the invention provides a marine equipment seawater extraction and observation device, including an extraction box 1. A sealed box door 4 is provided on the outside of the extraction box 1. A sealing strip is provided on the closed end of the sealed box door 4, and the sealed box door 4 is made of transparent material. A top shell 3 is fixedly connected to the upper end of the extraction box 1. A motor 17 is fixedly connected to one end of the inner side of the top shell 3. A lead screw 19 is rotatably connected to one end of the inner side of the extraction box 1. The output end of the motor 17 is connected to the lead screw 19 through a coupling. By setting the sealed box door 4, it is convenient for the staff to open the extraction box 1. The transparent material design makes it convenient for the staff to observe the extraction situation of the internal collection cylinder 12, thus achieving the purpose of easy observation. A fixing member 10 is threaded onto the lead screw 19. An extraction tube 7 is fixedly connected to the inner end of the fixing member 10. A threaded connector 24 is threaded onto the bottom of the extraction tube 7. An extraction head 8 is fixedly connected to the bottom of the threaded connector 24. A filter screen 25 is fixedly connected inside the threaded connector 24. The bottom of the extraction tube 7 extends through the bottom of the extraction box 1. A heating cylinder 11 is fixedly connected to the left inner end of the extraction box 1. By starting the motor 17 at the top, the lead screw 19 is rotated. Under the action of the threaded connection, the fixing member 10 causes the extraction tube 7 to move downwards, thereby... The extraction depth is adjusted, and then the water pump 15 is started. The water pump 15 can send seawater through the extraction head 8 and the extraction pipe 7 into the interior of the sealing plate 13, and finally into the interior of the collection cylinder 12 to complete the seawater extraction operation. The extraction head 8 at the bottom can be installed at the bottom of the extraction pipe 7 with the help of the threaded engagement. The internal filter screen 25 can filter some impurities in the seawater to avoid clogging the subsequent extraction pipe 16 and improve its performance. At the same time, the extraction head 8 can be directly disassembled and replaced after long-term use. The extraction tube 7 is movably connected to the inside of the heating cylinder 11. A heating component 5 is fixedly connected to the left side of the extraction box 1. A heating tube 6 is installed through the bottom of the heating component 5 and is connected to the heating cylinder 11. Several equally spaced nozzles 23 are installed inside the heating cylinder 11, and the nozzles 23 are designed to be inclined. During the recovery process, the fan structure and heating element inside the heating component 5 are activated to heat the air, thereby sending the hot air into the interior of the heating cylinder 11 through the heating tube 6 and spraying it outward through the nozzles 23. This dries the extraction tube 7 with seawater adhering to its surface, preventing the seawater adhering to its surface from dripping directly into the interior of the extraction box 1 and causing corrosion damage to the internal components, thus improving the protection of the internal components. A slide rod 18 is fixedly connected to the inner side of the extraction box 1. The slide rod 18 and the lead screw 19 are located on the same plane. The fixing part 10 is also slidably connected to the slide rod 18. By setting the slide rod 18, the fixing part 10 can be restricted to ensure the stable lifting and adjustment of the entire extraction assembly and improve the stability of the device. A pumping pipe 16 is installed through the top of the extraction pipe 7. A cylinder 14 is fixedly connected to the upper inner side of the extraction box 1. A sealing plate 13 is fixedly connected to the extended end of the cylinder 14. A sealing plug 22 is installed through the bottom of the sealing plate 13. The other end of the pumping pipe 16 is installed through the sealing plate 13 and the sealing plug 22. A water pump 15 is installed in the middle of the pumping pipe 16. The cylinder 14 can drive the sealing assembly to be raised and lowered, which facilitates the installation and disassembly of the collection cylinder 12. Secondly, it can connect the pumping pipe 16 and the collection cylinder 12 to achieve the pumping effect. Thirdly, the water pump 15 can achieve stable pumping. A base 21 is fixedly connected to the bottom right end of the inner side of the extraction box 1. A collection tube 12 is correspondingly provided inside the base 21. A corresponding mounting groove is provided inside the base 21, which matches the diameter of the collection tube 12, thereby completing the fixation of the collection tube 12. A connecting block 26 is fixedly connected to the right end of the inner middle of the extraction box 1. A U-shaped frame 20 is fixedly connected to the outer end of the connecting block 26. Cylinder 27 is fixedly connected to both ends of the outer side of the U-shaped frame 20. An arc-shaped clamping plate 28 is fixedly connected to the extended end of cylinder 27 through the U-shaped frame 20. A battery box 9 is fixedly connected to the right end of the outer side of the extraction box 1. A handle 2 is fixedly connected to the top of the top shell 3. When taking out the extracted collection cylinder 12, first open the sealing box door 4, then start the cylinder 14 at the top to drive the sealing plate 13 to move upward, so that the sealing plug 22 and the sealing plate 13 move upward, thereby causing its sealing component to detach from the top of the collection cylinder 12. Then, the cylinder 27 at both ends is started to drive the arc-shaped clamping plate 28 to retract inward and leave the surface of the collection cylinder 12. The staff can directly pull the collection cylinder 12 upward to take it out from the inside of the extraction box 1, complete the extraction and observation of the seawater, and improve its use effect.

[0019] Working principle: When in use, the operator holds the handle 2 and lifts the entire extraction box 1 to the surface of the seawater so that the extraction pipe 7 is aligned with the seawater. At this time, the motor 17 at the top is started to drive the lead screw 19 to rotate. Under the action of the threaded engagement, the fixing part 10 can drive the extraction pipe 7 to move downward, thereby adjusting the extraction depth. Then, the water pump 15 is started. The water pump 15 can send the seawater through the extraction head 8 and the extraction pipe 7 into the interior of the sealing plate 13, and finally into the interior of the collection cylinder 12, completing the seawater extraction operation. Staff observe the collection process of the collection cylinder 12 through the external sealed box door 4. After extraction is completed, the motor 17 reverses, causing the extraction tube 7 to gradually retract into the extraction box 1. During the retraction process, the fan structure and heating elements inside the heating component 5 are activated to heat the air. The hot air is then sent into the heating cylinder 11 through the heating pipe 6 and sprayed out through the nozzle 23 to dry the extraction tube 7 with seawater adhering to its surface. This prevents the seawater adhering to the surface from dripping directly into the extraction box 1 and causing corrosion damage to the internal components, thus improving the protection of the internal components. When it is necessary to remove the collected cylinder 12 after extraction, first open the sealing box door 4, then start the top cylinder 14 to drive the sealing plate 13 upward, so that the sealing plug 22 and the sealing plate 13 move upward, thereby causing the sealing assembly to detach from the top of the collected cylinder 12. Then, start the cylinders 27 at both ends to drive the arc-shaped clamping plate 28 to retract inward and leave the surface of the collected cylinder 12. The staff can then directly pull the collected cylinder 12 upward to remove it from the inside of the extraction box 1, completing the entire seawater extraction and observation, and improving its usage effect.
