Description

Technical Field

[0001] This utility model belongs to the field of marine biological sampling technology, and in particular relates to a sampling tool based on marine organism monitoring. Background Technology

[0002] Marine organism monitoring refers to the regular or continuous observation, measurement, and analysis of marine organisms to understand their health status, marine biodiversity, and marine pollution. The purpose of marine organism monitoring is to protect and maintain the health and sustainable development of the marine ecological environment. By monitoring the residual levels of harmful substances in marine organisms, pollution problems in the atmosphere, water quality, and seabed can be detected and controlled in a timely manner, reducing the impact of human activities on the marine environment and protecting the integrity of marine biological resources and ecosystems. Sampling devices are required to collect samples from marine organisms during marine organism monitoring.

[0003] Chinese patent publication number 202320140995.6 discloses an aquatic organism sampler, comprising a first frame, a second frame, guide rods, a pull rope, a handle, and a quick-push mechanism. A net is connected to the first frame, and a first connecting plate is fixed to the first frame. Multiple guide rods are fixed to the first connecting plate, and the ends of the multiple guide rods are connected to a second connecting plate. A handle is fixed to the second connecting plate, and the end of the handle is closed. A sliding plate is slidably mounted on the multiple guide rods. The second frame is fixed to the sliding plate, and a mesh is connected inside the second frame. The pull rope is fixed to the sliding plate. The quick-push mechanism includes a push rod and a first compression spring. The push rod is fixed to the sliding plate, passes through the second connecting plate, and is located inside the handle. The first compression spring abuts against the end of the push rod and the closed end of the handle. A locking mechanism that can lock the push rod is connected to the end of the handle away from the second connecting plate. This invention improves the convenience of collecting aquatic organisms.

[0004] However, existing technologies have the following problems when used:

[0005] During marine organism sampling, different organisms are often sampled using the same tools, which makes sampling difficult and can easily damage the organisms. Alternatively, operators may need to carry multiple tools and switch between them, which not only increases the burden of carrying them but also leads to cumbersome operating procedures, low sampling efficiency, and difficulty in adapting to the diverse needs of marine organism sampling. This reduces the effectiveness of marine organism monitoring and sampling devices and fails to meet the needs of marine monitoring work. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a sampling tool for monitoring marine organisms.

[0007] This technical solution includes,

[0008] A first support rod, one end of which is provided with a hook for contacting and hooking aquatic algae-like marine organisms;

[0009] The second support rod has a scraper fixed to one end, which is used to scrape and sample marine organisms such as barnacles and oysters.

[0010] The sampling rod has a first support rod and a second support rod rotatably connected to one end of the sampling rod via the same rotating shaft. Both the first support rod and the second support rod are provided with a limiting structure for positioning the first support rod or the second support rod on the sampling rod, so that the sampling tool can sample marine organisms.

[0011] Furthermore, one end of the first support rod is rotatably connected to the hook via a joint, and the end of the hook is formed with a curved hook portion. The plurality of joints and hooks are arranged in a ring array on the outer side wall of the first support rod.

[0012] Furthermore, a collection head is fixedly connected to one end of the scraper, and an insertion groove is provided on one side of the collection head. An insertion blade is fixedly connected to the inner cavity of the insertion groove. The insertion blade is inclined and set inside the collection head. The insertion groove is used to guide marine organisms into the cutting area of ​​the blade.

[0013] Furthermore, a rubber ring is provided on the outer wall of the first support rod, which houses and fixes multiple hooks, allowing the first support rod and hooks to rotate.

[0014] Furthermore, the limiting structure includes a limiting hole and a limiting rod. The limiting hole is radially opened on the side wall of the sampling rod. The side walls of the first support rod and the second support rod are both radially opened with sliding holes. The limiting rod is slidably connected to the inner cavity of the sliding hole. The limiting rod is used in conjunction with the limiting hole.

[0015] Furthermore, a positioning block is fixedly connected to the bottom of the limiting rod, and a spring is fixedly connected to one side of the positioning block. The two springs are respectively fixedly connected to the side wall of the first support rod and the side wall of the second support rod.

[0016] Furthermore, a bent end is formed between the collection head and the scraper section, and the inclination angle of the bent end is between degrees and degrees.

[0017] Furthermore, brushes are fixedly connected to both sides of the sampling head.

[0018] Furthermore, the hook is made of aluminum and is integrally molded.

[0019] Furthermore, a handle is fixedly connected to the other end of the sampling rod.

[0020] Compared with existing technologies, the sampling tool based on marine organism monitoring described in this utility model has the following advantages:

[0021] 1. This sampling tool integrates two sampling components—a sampling rod and a scraper—on the same rotating shaft. It is equipped with a limit structure that includes a spring reset function. The sampling components can be switched simply by pulling or releasing the limit rod, eliminating the need for complicated replacements and simplifying the operation process.

[0022] 2. For sampling algae, the ring-shaped articulated hooks can be used to hold the samples in multiple directions. The hooks can avoid obstacles by wrapping around the joints and have built-in blades to assist in cutting. The rubber rings can also store the hooks to prevent them from getting tangled.

[0023] 3. When sampling attached organisms such as barnacles and oysters, the scraper can scrape off the organisms, and the 30-45 degree bent end of the sampling head can fit against the attached surface. The insertion groove guides the organisms into the inclined blade area, improving cutting efficiency. Attached Figure Description

[0034] like Figures 1-4 As shown, a sampling tool based on marine organism monitoring includes: a first support rod 200, one end of which is provided with a hook 220 for contacting and hooking aquatic algae-like marine organisms;

[0035] The second support rod 300 has a scraper part 320 fixedly connected to one end. The scraper part 320 is used to scrape and sample marine organisms such as barnacles and oysters.

[0036] The sampling rod 100, the first support rod 200, and the second support rod 300 are rotatably connected to one end of the sampling rod 100 via the same rotating shaft 110. The rotating shaft 110 is rotatably connected to the sampling rod 100 via a bearing. After the first support rod 200 and the second support rod 300 are inserted outside the rotating shaft 110, their ends are detachably fixed to the outside of the rotating shaft 110 by a laterally inserted bolt (the bolt passes through the first support rod 200 or the second support rod 300 and is threaded into the rotating shaft 110). The first support rod 200 and the second support rod 300 are both provided with a limiting structure for positioning the first support rod 200 or the second support rod 300 on the sampling rod 100, so that the sampling tool can sample different marine organisms.

[0037] As a preferred example of this utility model, the sampling rod 100 serves as the core support component. One end of the sampling rod 100 is rotatably connected to the first support rod 200 and the second support rod 300 via the same rotating shaft 110, allowing for flexible switching between the two sampling components. When collecting algae-like marine organisms, the first support rod 200 can be rotated to align the hook 220 with the target, enabling the hook 220 to directly contact and firmly hook the algae, thus detaching the algae. When dealing with attached organisms such as barnacles and oysters, the second support rod 300 can be rotated to bring the scraper 320 close to the attachment surface for scraping and sampling. Simultaneously, the limiting structures on the first support rod 200 and the second support rod 300 can position the corresponding support rod on the sampling rod 100 after switching.

[0038] In the example of this application, one end of the first support rod 200 is rotatably connected to the hook 220 via a joint 210, and the end of the hook 220 is formed with a curved hook 221. Multiple joints 210 and hooks 220 are arranged in a ring array on the outer side wall of the first support rod 200.

[0039] As a preferred example of this utility model, one end of the first support rod 200 is rotatably connected to the hook 220 via a joint 210. When the hook 220 contacts an obstacle, the hook 220 can rotate around the joint 210 to disengage from the obstacle. Specifically, the joint 210 is rotatably connected to the hook 220 via a pivot and a torsion spring, enabling the hook 220 to cut algae. A curved blade can be installed in the curved hook portion 221 of the hook 220 to cut and sample algae.

[0040] In the example of this application, a collection head 330 is fixedly connected to one end of the scraper part 320. An insertion groove 340 is provided on one side of the collection head 330. An insertion blade 341 is fixedly connected to the inner cavity of the insertion groove 340. The insertion blade 341 is inclined and set in the collection head 330. The insertion groove 340 is used to guide marine organisms to insert into the cutting area of ​​the blade 341.

[0041] As a preferred example of this utility model, a sampling head 330 is fixedly connected to one end of the scraper part 320. The insertion groove 340 and the fixed insertion blade 341 provided on the sampling head 330 form a biological sampling structure: when the scraper part 320 scrapes off organisms such as barnacles and oysters from the attachment surface, the sampling head 330 can receive the scraped organisms. The insertion groove 340 can guide the organisms into the area of ​​the insertion blade 341. The insertion blade 341, which is set in the sampling head 330 at an inclined angle, can cut into the organisms and improve the sampling speed.

[0042] In the example of this application, a rubber ring 230 is provided on the outer side wall of the first support rod 200. The rubber ring 230 stores and fixes multiple hooks 220, so that the first support rod 200 and the hooks 220 can rotate.

[0043] As a preferred example of this utility model, the rubber ring 230 provided on the outer wall of the first support rod 200 allows the hooks 220 to rotate and converge from the end away from the first support rod 200 to the side closer to the first support rod 200. The rubber ring 230 can be used to store and fix multiple hooks 220. When the hooks 220 are not needed for sampling, the rubber ring 230 can gather and constrain the scattered hooks 220, preventing the hooks 220 from swinging randomly and getting tangled with other components.

[0044] In the example of this application, the limiting structure includes a limiting hole 120 and a limiting rod 311. The limiting hole 120 is radially opened on the side wall of the sampling rod 100. The side walls of the first support rod 200 and the second support rod 300 are both radially opened with sliding holes 310. The limiting rod 311 is slidably connected to the inner cavity of the sliding hole 310. The limiting rod 311 is used in conjunction with the limiting hole 120.

[0045] As a preferred example of this utility model, the limiting structure consists of a limiting hole 120 radially opened on the side wall of the sampling rod 100, and sliding holes 310 radially opened on the side walls of the first support rod 200 and the second support rod 300, and a limiting rod 311 slidably connected to the inner cavity of the sliding hole 310. In use, the limiting rod 311 is slid into the limiting hole 120, which quickly fixes the corresponding first support rod 200 and second support rod 300 to the sampling rod 100, preventing the first support rod 200 and second support rod 300 from rotating during sampling. When it is necessary to switch sampling components, the limiting rod 311 is pulled to disengage it from the limiting hole 120, and the switching can be completed without complicated disassembly steps, enabling the use of different sampling tools for different organisms.

[0046] In the example of this application, a positioning block 312 is fixedly connected to the bottom of the limiting rod 311, and a spring 313 is fixedly connected to one side of the positioning block 312. The two springs 313 are fixedly connected to the side wall of the first support rod 200 and the side wall of the second support rod 300, respectively.

[0047] As a preferred example of this utility model, the positioning block 312 fixed to the bottom of the limiting rod 311, and the spring 313 fixed to one side of the positioning block 312 and the other end fixed to the side wall of the first support rod 200 and the second support rod 300 respectively, provide automatic reset and stable support functions for the limiting structure. When the limiting rod 311 is pushed into the limiting hole 120, the spring 313 is in a contracted state, and its elastic force can be applied to the limiting rod 311 through the positioning block 312 to ensure stable limiting effect. When it is necessary to release the limit, simply pull the limiting rod 311 to disengage the limiting rod 311 from the limiting hole 120.

[0048] In the example of this application, a bent end 331 is formed between the collection head 330 and the scraper part 320, and the tilt angle of the bent end 331 is between 30 degrees and 45 degrees.

[0049] As a preferred example of this utility model, the bent end 331 formed between the collection head 330 and the scraper part 320 has an inclination angle of 30 to 45 degrees. This angle allows the collection head 330 to conform to common biological attachment surfaces such as reefs and ship hulls, so that the insertion groove 340 can still be aligned with the biological foot.

[0050] In the example of this application, brushes 332 are fixedly connected to both sides of the acquisition head 330.

[0051] As a preferred example of this utility model, the brushes 332 fixedly connected to both sides of the sampling head 330 can play a cleaning role during the sampling process and can sample and process marine organisms such as sea slugs.

[0052] In the example of this application, the hook 220 is made of aluminum in one piece.

[0053] As a preferred example of this utility model, the hook 220 is made of aluminum in one piece. Taking advantage of the lightweight nature of aluminum, it can effectively reduce the overall weight of the first support rod 200, thereby reducing the weight of the entire sampling tool, making it convenient for operators to hold and lift for sampling for extended periods.

[0054] In the example of this application, a handle 130 is fixedly connected to the other end of the sampling rod 100.

[0055] As a preferred example of this utility model, a handle 130 is fixedly connected to the other end of the sampling rod 100, which provides a grip support for the operator. The handle 130 can increase the contact area between the hand and the sampling rod 100 and distribute the pressure when the hand is gripping.

[0056] When using the device, the operator first pulls the limiting rod 311 inside the sliding hole 310 on the side wall of the first support rod 200, causing the limiting rod 311 to move out of the limiting hole 120. Then, the operator rotates the first support rod 200, causing the hook 220 to rotate to the working end. Subsequently, the hook 220 connected to one end of the first support rod 200 via the joint 210 can hook algae. Multiple joints 210 and hooks 220 arranged in a ring array can simultaneously hook algae from multiple directions. When the hook 220 contacts an obstacle, it can rotate around the joint 210 to disengage from the obstacle. If the hook 220 is not needed, the rubber ring 230 on the outer wall of the first support rod 200 can also store and fix the hook 220 to prevent it from getting tangled. When it is necessary to collect barnacles... When handling attached organisms such as oysters, the operator pulls the limiting rod 311 on the second support rod 300 to disengage the limiting rod 311 from the limiting hole 120. Then, the second support rod 300 is rotated to the working position via the rotating shaft 110. Releasing the limiting rod 311 allows it to be reset and fixed by the spring 313. At this time, the scraper part 320 at one end of the second support rod 300 can scrape the attached organism from the attachment surface. The scraped organism will be received by the collection head 330 fixed to the scraper part 320. The 30-45 degree bend end 331 between the collection head 330 and the scraper part 320 allows the collection head 330 to fit against the attachment surface. The insertion groove 340 on the collection head 330 will guide the organism into the inner cavity, and the inclined insertion blade 341 can cut the lower end of the organism, thus completing the use.

[0057] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
