Description

Technical Field

[0001] This invention relates to the field of water pollutant sampling technology, specifically to an integrated sampler for dock water pollution and fouling organisms. Background Technology

[0002] Terminals and port areas are complex habitats with intense land-sea interaction and are also the most densely populated areas of nearshore human activity. With the booming development of the global shipping industry and the intensification of coastal industrial activities, terminal waters are facing increasingly severe ecological and environmental challenges, requiring pollution control and remediation. These challenges mainly stem from two aspects: firstly, water pollution, including ballast water discharged from ships, domestic sewage, oil spills, and industrial pollutants, pesticides, and persistent organic pollutants from land. These pollutants accumulate in terminal waters, posing a direct threat to water quality safety; secondly, biofouling and invasive species. The hydraulic structures of terminals (such as pile foundations and revetments) provide ideal attachment substrates for fouling organisms. Simultaneously, the discharge of ballast water from ships has become a major pathway for the cross-regional spread of harmful alien organisms (such as red tide algae and barnacles), leading to imbalances in the local ecosystem and a decline in biodiversity. Therefore, it is necessary to take samples from the area surrounding the terminal for testing.

[0003] When sampling shallow fouling organisms, it is necessary to do so after the tide has receded, when the wharf piles or the upper part of the revetment are exposed. Researchers can directly use shovels, scrapers or wire brushes to scrape the organisms into the collection net bag. This method is highly dependent on the tide time and cannot obtain samples below the low tide line.

[0004] When sampling deep-fouled organisms, researchers or operators typically need to dive underwater to complete the sampling task directly. However, in near-shore waters such as docks, the turbidity and high levels of suspended matter often result in very low underwater visibility, increasing the safety risks of diving operations. This can not only affect the accuracy and completeness of the sampling data but also pose a potential threat to the personal safety of divers. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an integrated sampler for sampling pollution and fouling organisms in wharf water. The main purpose is to solve the problems of deep biological sampling in existing technologies, which require diving operations, pose safety risks, and are affected by water turbidity, thus impacting sampling accuracy.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An integrated sampler for water pollution and fouling organisms at a wharf includes a mounting base plate bolted to the top of a wharf foundation pile. Below the mounting base plate is an integrated sampling component for integrated sampling of water and fouling organisms. The integrated sampling component includes a fouling organism collection mechanism for scraping and collecting fouling organisms, a seawater collection mechanism for collecting seawater, and an auxiliary force-applying mechanism to facilitate scraping by the fouling organism collection mechanism. Above the mounting base plate is a driving component for moving the integrated sampling component, and a liquid level positioning component for measuring the depth of the integrated sampling component.

[0008] As a further embodiment of the present invention, the integrated sampling assembly includes an extension rod. A positioning groove is provided inside the mounting base, and the extension rod is located inside the positioning groove. The extension rod is slidably connected to the mounting base. A connecting frame is fixedly connected to the bottom end of the extension rod by bolts. The fouling organism collection mechanism is located below the connecting frame. The fouling organism collection mechanism includes a first electric push rod that is bolted to the bottom surface of the connecting frame. A first corrugated waterproof pipe is installed on the surface of the first electric push rod. The first corrugated waterproof pipe is used to isolate the push rod of the first electric push rod from seawater. A fouling organism removal shell is bolted to the push rod of the first electric push rod. A blade is installed at the end of the fouling organism removal shell near the dock pile foundation, and the blade is used to scrape off fouling organisms.

[0009] As a further embodiment of the present invention, the fouling organism removal shell is a hollow square pyramidal structure, and the blade is located at the opening of the fouling organism removal shell. The interior of the fouling organism removal shell is provided with a fouling organism collection pocket, which is used to centrally store the fouling organisms.

[0010] As a further embodiment of the present invention, a seawater collection mechanism is disposed on the side of the fouling organism removal shell away from the dock pile foundation. The seawater collection mechanism includes a water storage bottle that is screwed onto one end of the fouling organism removal shell by a screw. A connecting pipe is fixedly connected to the end of the water storage bottle away from the fouling organism removal shell, and a valve is installed inside the connecting pipe.

[0011] As a further embodiment of the present invention, an exhaust pipe is provided inside the connecting pipe, and a three-way valve is installed at the end of the exhaust pipe away from the connecting pipe. The exhaust pipe is connected to the air pump through the three-way valve, and a baffle is rotatably connected to the inner wall of the water storage bottle near the opening on the side of the dirt-removing biological shell through a hinge.

[0012] As a further embodiment of the present invention, the auxiliary force-applying mechanism is disposed below the connecting frame and located on one side of the fouling organism collection mechanism. The auxiliary force-applying mechanism includes a second electric push rod fixedly connected to the connecting frame by bolts. A second corrugated waterproof pipe is installed on the surface of the second electric push rod. The second corrugated waterproof pipe is used to isolate the push rod of the second electric push rod from seawater. A positioning block is fixedly connected to the push rod of the second electric push rod by bolts. A positioning plate is provided on the side of the positioning block near the dock pile foundation. The positioning plate is in contact with the dock pile foundation. The positioning plate is slidably connected to the positioning block. A first float is fixedly connected to the bottom end of the positioning plate.

[0013] As a further embodiment of the present invention, the drive assembly includes a geared motor that is bolted to the top surface of the mounting base. The output shaft of the geared motor is keyed to a gear. A toothed plate is fixedly connected to the side of the extension rod facing the gear. The gear and the toothed plate mesh with each other. A stop bar is rotatably connected to the top surface of the mounting base through a bearing seat. The stop bar is used to limit the extension rod.

[0014] As a further embodiment of the present invention, the liquid level positioning assembly includes a float plate disposed on one side of the extension rod, a pointer fixedly connected to one side of the float plate, a depth dimension chart engraved on the side of the extension rod facing the pointer, a positioning rod being bolted to the top surface of the float plate, the top end of the positioning rod penetrating the surface of the mounting base plate, a hand-tightening bolt being disposed on the top surface of the mounting base plate, and a rubber pad being fixedly connected to one end of the hand-tightening bolt near the positioning rod, and the rubber pad being in contact with the positioning rod.

[0015] As a further embodiment of the present invention, a groove is provided on the side of the extension rod away from the toothed plate. A wave-blocking cover is slidably connected to the inside of the groove via a slider. The wave-blocking cover is placed on the surface of the float plate, and sliders are fixedly connected to both ends of the float plate. The sliders are slidably connected to the slide rails corresponding to the inner wall of the wave-blocking cover. A linkage shell is fixedly connected to one side of the wave-blocking cover. A locking rod is slidably connected inside the linkage shell. A toothed plate is fixedly connected to one side of the locking rod via bolts. A toothed groove is provided inside the linkage shell at a position corresponding to the toothed plate. The toothed groove is used to mesh with the toothed plate. A lead screw is provided on the top surface of the mounting base plate. The lead screw cooperates with the locking rod via a nut.

[0016] As a further embodiment of the present invention, a second float is fixedly connected to the outer wall of the wave barrier, the second float being used to limit the position of the wave barrier.

[0017] Compared with the prior art, the present invention provides an integrated sampler for dock water pollution and fouling organisms, which has the following beneficial effects:

[0018] 1. This invention integrates a fouling organism collection mechanism (fouling organism removal shell, collection bag) and a seawater collection mechanism (water storage bottle, baffle) into a single execution end through an integrated structure. In a single dive and scraping action, it can not only remove and collect fouling organisms on the dock pile foundation, but also simultaneously use water pressure to collect seawater pollution samples at that depth. This avoids the cumbersome process of traditional sampling methods that require the separate deployment of different equipment and two separate operations, and significantly improves the efficiency of on-site sampling.

[0019] 2. This invention, through an auxiliary force-applying mechanism, provides reverse support force, making the force more even when scraping the fouled biological exfoliating shell. This not only improves the scraping effect but also protects the structure of the exfoliating shell and extends the service life of the equipment.

[0020] 3. This invention uses an air pump to fill the water storage bottle with air, and uses the air pressure to tightly close the baffle, ensuring that the bottle is always dry. When the predetermined depth is reached and scraping is initiated, the three-way valve switches the passage, allowing seawater to push open the baffle and enter the bottle under water pressure. This precise control mechanism of "emptying first and then filling with water" effectively prevents the mixing of upper water bodies, ensures a strict spatial correspondence between the collected water sample and the contaminated biological sample, and guarantees the scientific validity and purity of the sample.

[0021] 4. This invention achieves intuitive depth reading by setting up a float with a pointer and an extension rod engraved with depth dimensions. The addition of a wave-blocking cover with a second float effectively buffers the impact of waves on the float, greatly reducing measurement errors caused by waves and ensuring that the sampling mechanism can accurately dock at the preset research depth.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] Please see Figures 1-10 As shown, an integrated sampler for water pollution and fouling organisms at a wharf includes a mounting base plate 1 bolted to the top of the wharf foundation piles, an integrated sampling component 2 for integrated sampling of water and fouling organisms, a driving component 3 for moving the integrated sampling component 2, and a liquid level positioning component 4 for measuring the depth of the integrated sampling component 2.

[0040] The integrated sampling assembly 2 includes a fouling organism collection mechanism for scraping and collecting fouling organisms. The fouling organism collection mechanism includes a first electric push rod 203 that is bolted to the bottom of the connecting frame 202. A first corrugated waterproof pipe 204 is installed on the surface of the first electric push rod 203. The first corrugated waterproof pipe 204 is used to isolate the push rod of the first electric push rod 203 from the seawater when the push rod of the first electric push rod 203 extends, so as to prevent the push rod of the first electric push rod 203 from contacting the seawater and thus preventing the seawater from corroding the push rod.

[0041] The push rod of the first electric push rod 203 is bolted to a fouling organism removal shell 205. The fouling organism removal shell 205 is a hollow square pyramidal structure. A blade is bolted to the end of the fouling organism removal shell 205 near the dock pile foundation, and the blade is located at the opening of the fouling organism removal shell 205. When the fouling organism removal shell 205 is close to the dock pile foundation, the blade will cut into the interior of the fouling organism. Then the first electric push rod 203 is activated, and the first electric push rod 203 will drive the fouling organism removal shell 205 to move upward. At this time, the blade will scrape off the fouling organism, and the fallen fouling organism will enter the interior of the fouling organism removal shell 205, thereby realizing the sampling of the fouling organism.

[0042] The inside of the fouling organism removal shell 205 is equipped with a fouling organism collection pocket 206. Fouling organisms that enter the fouling organism removal shell 205 will eventually fall into the fouling organism collection pocket 206. Because the fouling organism collection pocket 206 is woven mesh, it will cover the fouling organisms, thereby preventing the fouling organisms from floating out of the inside of the fouling organism collection pocket 206.

[0043] Furthermore, the fouling organism collection bag 206 can separate fouling organisms from seawater after being moved away from the water body, making it easier for operators to sample and retrieve fouling organisms.

[0044] The integrated sampling assembly 2 also includes a seawater collection mechanism for collecting seawater. The seawater collection mechanism includes a water storage bottle 207 that is screwed onto one end of the fouling organism removal shell 205 via a screw. When installing the water storage bottle 207, simply align the bottle opening of the water storage bottle 207 with the screw of the fouling organism removal shell 205, and then rotate the water storage bottle 207 to connect it to the fouling organism removal shell 205. A connecting pipe 208 is fixedly connected to the end of the water storage bottle 207 away from the fouling organism removal shell 205. A valve 209 is installed inside the connecting pipe 208. After seawater enters the interior of the water storage bottle 207 through the fouling organism removal shell 205, the valve 209 can seal the other end of the water storage bottle 207.

[0045] An exhaust pipe 216 is installed inside the connecting pipe 208. A three-way valve 217 is installed at the end of the exhaust pipe 216 away from the connecting pipe 208. The exhaust pipe 216 is connected to the air pump 218 through the three-way valve 217. After connecting the water storage bottle 207 to the soiled biological removal shell 205, one end of the exhaust pipe 216 is connected to the connecting pipe 208. Force is applied to the three-way valve 217 to connect the exhaust pipe 216 to the air outlet of the air pump 218, and then the air pump 218 is started. 8. The air pump 218 injects air into the exhaust pipe 216, filling the water storage bottle 207 with gas. The opening on the inner wall of the water storage bottle 207 near the fouling bio-removal shell 205 is connected to a baffle 210 via a hinge. When the water storage bottle 207 is filled with air, the baffle 210 will block the same end of the water storage bottle 207 as the fouling bio-removal shell 205, so that water will not enter the water storage bottle 207 when the fouling bio-removal shell 205 submerges.

[0046] When the fouling organism scraper 205 scrapes off the fouling organism, force is applied to the three-way valve 217, so that the exhaust pipe 216 is connected to the outside. Due to water pressure, the seawater will push open the baffle 210, and the seawater will enter the interior of the water storage bottle 207. The gas inside the water storage bottle 207 will be discharged, thus completing the collection of seawater. When the water storage bottle 207 is exposed above the water surface, force is applied to the valve 209 manually to seal one end of the water storage bottle 207.

[0047] The integrated sampling assembly 2 also includes an auxiliary force application mechanism to facilitate the scraping of contaminated organisms by the collection mechanism. The auxiliary force application mechanism includes a second electric push rod 211 fixedly connected to the connecting frame 202 by bolts. A second corrugated waterproof pipe 212 is installed on the surface of the second electric push rod 211. The second corrugated waterproof pipe 212 is used to isolate the push rod of the second electric push rod 211 from the seawater, so as to prevent the push rod of the second corrugated waterproof pipe 212 from contacting the seawater, thereby preventing the seawater from corroding the push rod.

[0048] The push rod of the second electric push rod 211 is fixedly connected to the positioning block 213 by bolts. When the positioning block 213 is placed, the fouling organism removal shell 205 and the positioning block 213 are located on opposite sides of the wharf pile foundation. When it is necessary to sample the fouling organisms, the second electric push rod 211 is activated. The push rod of the second electric push rod 211 will pull the positioning block 213 towards the wharf pile foundation until the positioning plate 214 and the wharf pile foundation are in contact with each other, so that the fouling organism removal shell 205 can cut into the fouling organisms more forcefully.

[0049] A positioning plate 214 is provided on the side of the positioning block 213 near the dock pile foundation. The positioning plate 214 is in contact with the dock pile foundation and is slidably connected to the positioning block 213. Then, the first electric push rod 203 is activated. When the first electric push rod 203 drives the fouling organism removal shell 205 to rise, the positioning block 213 will move on the surface of the positioning plate 214, so that the fouling organism removal shell 205 scrapes off the fouling organisms more smoothly.

[0050] The bottom end of the positioning plate 214 is fixedly connected to the first float 215, so that when the positioning plate 214 enters the water, the first float 215 will float up due to buoyancy, so that the positioning block 213 will be located at the bottom of the positioning plate 214.

[0051] It should be noted that the electric push rod in this application has IP69K level protection and can be used with magnetic switches, proximity switches or photoelectric switches to achieve precise control of the push rod's extension and retraction displacement. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0052] The drive assembly 3 includes a geared motor 301 that is bolted to the top surface of the mounting base plate 1. The output shaft of the geared motor 301 is keyed to a gear 302. The integrated sampling assembly 2 includes an extension rod 201. A positioning groove is provided inside the mounting base plate 1. The extension rod 201 is located inside the positioning groove. A toothed plate is fixedly connected to the side of the extension rod 201 facing the gear 302. The gear 302 and the toothed plate mesh with each other.

[0053] It should be noted that the geared motor 301 is existing technology and is a speed reduction transmission device with integrated self-locking function. Its core feature is to achieve "reverse self-locking" through mechanical structure (such as worm gear) - that is, the output shaft (load end) can only be driven to rotate by the input shaft (motor end), and the load reaction force of the output shaft cannot make the input shaft rotate in the opposite direction. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0054] When sampling is required, the connecting frame 202 is bolted to the bottom of the extension rod 201, and then the extension rod 201 is placed inside the positioning groove so that the toothed plate and the gear 302 mesh with each other. Then the reduction motor 301 is started, and the reduction motor 301 drives the gear 302 to rotate, so that the extension rod 201 will drive the connecting frame 202 to move up and down.

[0055] A stop bar 303 is rotatably connected to the top surface of the mounting base 1 via a bearing seat. The stop bar 303 is used to limit the extension rod 201. Rotating the stop bar 303 causes the stop bar 303 to laterally limit the extension rod 201.

[0056] The liquid level positioning component 4 includes a float 402 disposed on one side of the extension rod 201. A pointer 406 is fixedly connected to one side of the float 402. A depth dimension table 407 is engraved on the side of the extension rod 201 facing the pointer 406. When the extension rod 201 enters the water, the float 402 is placed in the water and floats on the water surface. The pointer 406 will point to the depth dimension table 407, thus showing the depth of the extension rod 201.

[0057] A positioning rod 404 is bolted to the top surface of the float plate 402. The top end of the positioning rod 404 penetrates the surface of the mounting base plate 1. A hand-tightening bolt 405 is provided on the top surface of the mounting base plate 1. A rubber pad is fixedly connected to one end of the hand-tightening bolt 405 near the positioning rod 404. The rubber pad and the positioning rod 404 are in close contact. When the float plate 402 floats on the water surface, force is applied to the hand-tightening bolt 405 to make the rubber pad and the positioning rod 404 fit tightly together, thereby locking the position of the float plate 402 and preventing the slider 403 from shaking continuously.

[0058] The extension rod 201 has a groove on the side away from the toothed plate. A wave blocking cover 401 is slidably connected inside the groove via a slider. The wave blocking cover 401 covers the surface of the float 402 and can block the waves, reducing the force exerted by the waves on the slider 403.

[0059] Furthermore, sliders 403 are fixedly connected to both ends of the float plate 402. The sliders 403 are slidably connected to the corresponding slide rails on the inner wall of the wave barrier cover 401, which can prevent the float plate 402 from moving laterally.

[0060] A linkage shell 409 is fixedly connected to one side of the wave barrier 401. A locking rod 410 is slidably connected inside the linkage shell 409. A toothed plate is fixedly connected to one side of the locking rod 410 by bolts. A toothed groove is opened inside the linkage shell 409 at a position corresponding to the toothed plate. The toothed groove is used to mesh with the toothed plate. A lead screw 411 is provided on the top surface of the mounting base plate 1. The lead screw 411 cooperates with the locking rod 410 through a nut.

[0061] When the wave barrier 401 is placed underwater, the linkage shell 409 will slide on the surface of the locking rod 410 until the wave barrier 401 stops moving. Then, the lead screw 411 is rotated, and the toothed plate of the locking rod 410 will move towards the tooth groove, so that the toothed plate and the tooth groove mesh with each other to position the wave barrier 401.

[0062] A second float 408 is fixedly connected to the outer wall of the wave barrier 401. The second float 408 is used to limit the position of the wave barrier 401.

[0063] When the wave blocking cover 401 is submerged, the second float 408 will float on the surface, while half of the wave blocking cover 401 will be underwater, thus blocking the waves and reducing the swaying of the float 402.

[0064] In practical use, the mounting base plate 1 is first securely installed on top of the dock foundation piles using bolts to ensure the stability of the entire sampler's foundation. Next, the connecting frame 202 is bolted to the bottom of the extension rod 201, completing the connection between the sampling execution part and the lifting body.

[0065] Then, the assembled extension rod 201 is placed in the positioning groove opened inside the mounting base plate 1, so that the tooth plate of the extension rod 201 facing the gear 302 is precisely meshed with the gear 302 that is keyed to the output shaft of the reduction motor 301.

[0066] Subsequently, the stop bar 303, which is rotatably connected to the top surface of the mounting base 1 via the bearing seat, is rotated to limit the extension rod 201 laterally, preventing the extension rod 201 from shifting during movement.

[0067] For the preparation of the fouling organism collection mechanism, it is necessary to check whether the first corrugated waterproof pipe 204 installed on the surface of the first electric push rod 203 is intact, to ensure that it can effectively isolate the push rod of the first electric push rod 203 from the seawater and avoid corrosion.

[0068] The fouling organism removal shell 205 is a hollow square pyramid structure. The bolt installation blade at the end near the dock pile foundation should be kept sharp to ensure that it can cut smoothly into the interior of the fouling organism.

[0069] The textile mesh-like fouling organism collection bag 206 inside the fouling organism removal shell 205 must be confirmed to be intact and undamaged to ensure that the collected fouling organisms do not float out and to facilitate subsequent seawater removal.

[0070] Regarding the seawater collection mechanism, the water storage bottle 207 is screwed onto one end of the fouling organism removal shell 205 using a screw barrel. During installation, ensure that the bottle opening is concentric with the screw barrel and rotate it until a tight connection is achieved.

[0071] Then connect one end of the exhaust pipe 216 to the connecting pipe 208, apply force to the three-way valve 217 to connect the exhaust pipe 216 to the air outlet of the air pump 218, start the air pump 218 to inject air into the exhaust pipe 216 until the water storage bottle 207 is full of gas. At this time, the baffle 210 connected by a hinge at the opening on the inner wall of the water storage bottle 207 near the decontamination shell 205 will block the end of the water storage bottle 207 connected to the decontamination shell 205 due to the internal air pressure, preventing water from entering when diving.

[0072] The second electric push rod 211 of the auxiliary force-applying mechanism is fixedly connected to the connecting frame 202 by bolts, and the second corrugated waterproof pipe 212 on its surface also serves to isolate the push rod from seawater. The positioning block 213 is fixedly connected to the push rod of the second electric push rod 211 by bolts, ensuring that the fouling organism removal shell 205 and the positioning block 213 are located on opposite sides of the wharf pile foundation during placement. The positioning plate 214 on the side of the positioning block 213 closest to the wharf pile foundation should be able to slide smoothly, and the first float 215 fixedly connected to its bottom end can use buoyancy to keep the positioning block 213 initially located at the bottom of the positioning plate 214.

[0073] In the operation of the depth measurement mechanism's liquid level positioning component 4, the wave barrier 401 is placed underwater, and the linkage housing 409 slides on the surface of the locking rod 410. Once the wave barrier 401 stops moving, the lead screw 411 on the top surface of the mounting base plate 1 is rotated. Through the engagement of the nut and the locking rod 410, the toothed plates of the locking rod 410 move towards the tooth groove and mesh with each other, thereby positioning the wave barrier 401. The second float 408 on the outer wall of the wave barrier 401 floats on the water surface, keeping half of the wave barrier 401 underwater, thus blocking waves and reducing the swaying of the float plate 402. Subsequently, the float plate 402 is placed in the water, and the sliders 403 at both ends slide against the slide rails on the inner wall of the wave barrier 401, preventing lateral movement.

[0074] The top of the positioning rod 404 on the top surface of the float 402 penetrates the surface of the mounting base plate 1. When the float 402 floats on the water surface, force is applied to the hand-tightening bolt 405 on the top surface of the mounting base plate 1, so that the rubber pad at one end of it fits tightly with the positioning rod 404, locking the position of the float 402. At this time, the pointer 406 on one side of the float 402 will point to the depth dimension table 407 on the extension rod 201 to read the diving depth.

[0075] The reduction motor 301 is activated, driving the gear 302 to rotate. Through the meshing of the gear plate and the gear 302, the extension rod 201 moves the connecting frame 202 and the sampling mechanism below downwards. During the descent of the extension rod 201, the depth is monitored in real time by the liquid level positioning component 4 until the predetermined sampling position is reached. At this time, the second electric push rod 211 is activated, pulling the positioning block 213 towards the dock pile foundation until the positioning plate 214 is in contact with the dock pile foundation. Then, the first electric push rod 203 is activated, driving the fouling organism removal shell 205 upwards. The blade at the opening of the fouling organism removal shell 205 cuts into the fouling organism and scrapes it off. The fouling organism falls into the fouling organism removal shell 205 and finally enters the fouling organism collection bag 206. While the fouling organism removal shell 205 scrapes away fouling organisms, force is applied to the three-way valve 217, connecting the vent pipe 216 to the outside. Seawater, under water pressure, pushes open the baffle 210 and enters the storage bottle 207, completing seawater collection. After sampling, the reduction motor 301 is restarted, causing the extension rod 201 to lift the sampling mechanism to the water surface. Once above the surface, force is manually applied to the valve 209 to seal one end of the storage bottle 207, preventing seawater leakage. Finally, the fouling organism collection bag 206 is removed from the fouling organism removal shell 205, yielding the collected fouling organisms. The collected seawater sample can also be obtained by unscrewing the storage bottle 207, completing the entire sampling process.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
