Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sampling device technology, and in particular relates to an intertidal sampling device. Background Technology
[0002] Intertidal zone surveys are typically required during marine environmental status investigations. The survey locations and sections employ different methods depending on the specific environment. Based on local tidal parameters, the intertidal zone is divided into high tide, mid-tide, and low tide zones to assess the composition, abundance, and horizontal and vertical distribution of biological species in different habitats. During intertidal zone surveys, it is essential to obtain marine biological quality parameters, and different tools are used to investigate the seabed sediment for different parameters.
[0003] During sampling, tools such as shovels can be used for digging when encountering sections of sand, mudflats, or soft bottoms. However, when facing sections of hard bottoms such as rocks, it is difficult to dig out organisms such as oysters and mussels attached to the rocks. In conventional sampling, tools such as chisels, hammers, and scrapers are usually used for separation. The main purpose is to use the prying force of hammers and chisels to separate the organisms along with their attachment sites from the rock body, avoiding directly breaking the shells. However, in practice, hammering is quite strenuous, and it is difficult to control the angle and force, which can easily cause damage and contamination. In addition, oyster shells can also easily cause injury during the operation. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned technical problems by providing an intertidal sampling device that is more efficient than a hammer and chisel, causes less damage to the rock, can collect small fragments, and is more convenient to use than a hammer and chisel for areas that are difficult to reach.
[0005] In view of this, the present invention provides an intertidal sampling device, comprising:
[0006] The mounting frame has an elastic arc plate installed at its end, and the mounting frame and the elastic arc plate are fixedly connected to a net bag for receiving the organism.
[0007] The upper end of the mounting bracket is fixed with a support plate, and the upper end of the support plate is detachably mounted with an output pipe two. One end of the output pipe two is connected to a power source for flushing the organism, and the other end of the output pipe two is connected to an output pipe one through a pressure control valve. A connector is detachably mounted at the end of the output pipe one, and multiple universal delivery pipes are detachably mounted on the outside of the connector, and nozzles are detachably mounted on the multiple universal delivery pipes for flushing the organism.
[0008] In this technical solution,
[0009] Furthermore, the elastic arc sheet is integrally molded from flexible rubber material.
[0010] Furthermore, the elastic arc plate is embedded in the mounting bracket, and the projection position of the connector on the mounting bracket does not exceed the spatial range defined by the mounting bracket.
[0011] Furthermore, a hand-held plate is fixed to the end of the mounting bracket away from the elastic arc plate, and a handle is fixed to the upper end of the hand-held plate.
[0012] Furthermore, a second clamp is fixed at the upper end of the support plate, and a first clamp is provided at the upper end of the second clamp. The first clamp and the second clamp are detachably connected, and the second output pipe is disposed between the first clamp and the second clamp.
[0013] Furthermore, the two ends of the pressure control valve are detachably connected to output pipe two and output pipe one, respectively.
[0014] Furthermore, the universal conveying pipe is made of metal corrugated pipe and can be bent and adjusted at multiple angles along the axial and radial directions.
[0015] Furthermore, a circular shell is installed at the end of the output pipe away from the pressure control valve. A filter screen is detachably installed inside the circular shell. A threaded disc is detachably installed on the circular shell. A connecting pipe is installed on the threaded disc. A flexible hose is connected to the end of the connecting pipe, and the flexible hose is connected to an external power source.
[0016] The end of the circular shell away from the second output pipe has a threaded groove, and the inner wall of the threaded groove has an installation groove. The filter screen can be detachably installed in the installation groove, and the threaded disc extends into the threaded groove for threaded connection.
[0017] The beneficial effects of this utility model are:
[0018] When sampling oysters on rocks, this invention involves bending the universal delivery pipe according to the oyster's attachment position on the rock, adjusting the nozzle to the appropriate location, and aligning the nozzle with the gap between the oyster and the rock. The worker holds the entire device by hand, with the elastic arc plate fitting against the rock. The hose is then connected to an external water pump, which pumps water into the installation trough. A filter screen filters impurities from the water. The filtered water flows through output pipe two, a pressure control valve, output pipe one, a connector, and the universal delivery pipe, and is then sprayed out through the nozzle, washing the oysters off. The washed-off oysters fall into a net bag for collection. The pressure control valve can be adjusted to regulate the water pressure, achieving a higher efficiency than hammers and chisels, less damage to the rock, and the ability to collect small individuals from debris. It is also more convenient than hammers and chisels for areas that are difficult to reach or exert force on. Attached Figure Description

[0032] Please see Figures 1 to 6 This utility model provides an intertidal sampling device, comprising:
[0033] Mounting frame 2, with elastic arc sheet 3 installed at the end of mounting frame 2, and a net bag 1 fixedly connected to mounting frame 2 and elastic arc sheet 3 for receiving organisms;
[0034] The upper end of the mounting bracket 2 is fixed with a support plate 15, and the upper end of the support plate 15 is detachably mounted with an output pipe 2 9. One end of the output pipe 2 9 is connected to a power source for flushing organisms, and the other end of the output pipe 2 9 is connected to an output pipe 1 7 through a pressure control valve 8. A connector 6 is detachably mounted at the end of the output pipe 1 7. Multiple universal delivery pipes 5 are detachably mounted on the outside of the connector 6, and nozzles 4 are detachably mounted on the multiple universal delivery pipes 5 for flushing organisms.
[0035] As a preferred example of this utility model, the mounting frame 2 serves as the main support structure of the device, with the elastic arc plate 3 installed at its end and the net bag 1 fixed at its lower end forming a receiving device. When water flow is used to flush oysters and other organisms on the reef, the elastic arc plate 3 can conform to the surface of the reef, guiding the flushed organisms smoothly into the net bag 1, avoiding loss of organisms due to falling during sampling. At the same time, the support plate 15 fixed at the upper end of the mounting frame 2 provides a stable installation foundation for the water conveyance system. The output pipe 2 9, which can be detachably installed on the support plate 15, the pressure control valve 8 connected to the end of the output pipe 2 9, the output pipe 1 7 connected to the other end of the pressure control valve 8, the connector 6 detachably installed at the end of the output pipe 1 7, and the multiple universal delivery pipes 5 with nozzles 4 detachably installed outside the connector 6 together constitute a flexible and controllable flushing system. The universal delivery pipe 5 can be adjusted to different angles, allowing the nozzle 4 to spray the oysters attached to the reef from multiple angles. The pressure control valve 8 can precisely control the water pressure, ensuring that the organisms are effectively removed from the reef while reducing damage and contamination caused by excessive pressure. This solves the problems of traditional tools being difficult to operate, such as the difficulty in striking and controlling the angle and force, making the sampling process more efficient, stable, and less damaging to the organisms.
[0036] Furthermore, the elastic arc sheet 3 is integrally molded from flexible rubber material.
[0037] Furthermore, the elastic arc plate 3 is embedded in the mounting bracket 2, and the projection position of the connector 6 on the mounting bracket 2 does not exceed the space range defined by the mounting bracket 2.
[0038] As a preferred example of this utility model, the elastic arc plate 3 is made of rubber elastic material. Rubber material itself has good elasticity and flexibility, allowing the elastic arc plate 3 to adapt to different shapes of the reef surface and fit tightly against the reef. On the one hand, this greatly enhances the net 1's ability to catch washed-down organisms, preventing them from leaking out through the gaps between the elastic arc plate 3 and the reef, ensuring the integrity of the sampling. On the other hand, during the sampling process, when the device comes into contact with the reef, the rubber elastic material provides good cushioning, avoiding hard collisions between the rigid structure such as the mounting frame 2 and the reef, reducing damage to the device caused by collisions, and significantly improving the applicability and durability of the device in complex and varied reef environments, allowing the device to work stably on various irregular reef surfaces.
[0039] Furthermore, a hand-held plate 12 is fixed to the end of the mounting bracket 2 away from the elastic arc plate 3, and a handle 13 is fixed to the upper end of the hand-held plate 12.
[0040] As a preferred example of this utility model, the hand-held plate 12 fixed to the end of the mounting frame 2 away from the elastic arc plate 3 and the handle 13 fixed to the upper end of the hand-held plate 12 facilitate the actual operation of the operator. The hand-held plate 12 provides a stable support surface for the operator's hands, while the handle 13 allows the operator to hold it comfortably. This allows the operator to more flexibly control the position and angle of the entire device, easily adjusting the receiving position of the net bag 1 or changing the rinsing direction of the nozzle 4. At the same time, the stable grip point reduces hand fatigue during long-term sampling, allowing the operator to maintain a stable operating state, improving the controllability of the entire rinsing and receiving process, and ensuring that the sampling work can be carried out smoothly and efficiently.
[0041] Furthermore, a second clamp 16 is fixed to the upper end of the support plate 15, and a first clamp 14 is provided on the upper end of the second clamp 16. The first clamp 14 and the second clamp 16 are detachably connected, and the second output pipe 9 is located between the first clamp 14 and the second clamp 16.
[0042] As a preferred example of this utility model, the clamp 16 fixed to the upper end of the support plate 15 is bolted to the clamp 14 to secure the output pipe 9. The clamps 14 and 16 cooperate to firmly clamp the output pipe 9 in the middle, effectively preventing it from shaking under the impact of water flow. Furthermore, this detachable bolted connection makes the installation and removal of the output pipe 9 very convenient. When maintenance, replacement, or adjustment of the installation position of the output pipe 9 is required, simply loosening the bolts is sufficient, greatly enhancing the maintainability and flexibility of the device and allowing for rapid adjustments to different sampling scenarios.
[0043] Furthermore, the two ends of the pressure control valve 8 are detachably connected to output pipe 2 9 and output pipe 1 7, respectively.
[0044] As a preferred example of this utility model, the flanges at both ends of the pressure control valve 8 are connected to the flanges at the ends of the second output pipe 9 and the flanges on the first output pipe 7 via bolts or threads. The flange connections themselves have good sealing and robustness, effectively preventing leakage during water delivery, ensuring stable water pressure, and guaranteeing that the flushing effect is not affected. Simultaneously, the detachable nature of the flange connections facilitates the installation, commissioning, and replacement of the pressure control valve 8. When dealing with different types and adhesion strengths of organisms, pressure control valves 8 with different pressure ranges may be required. Through this connection method, operators can quickly replace the appropriate pressure control valve 8 to adapt to different sampling needs, thereby improving sampling efficiency and ensuring effective organism removal under various conditions.
[0045] Furthermore, the universal delivery pipe 5 is made of metal corrugated pipe and can be bent and adjusted at multiple angles along the axial and radial directions.
[0046] As a preferred example of this utility model, the multiple annular grooves on the universal delivery pipe 5 allow it to bend flexibly, enabling the pipe to easily adjust its bending angle according to actual needs. This, in turn, drives the nozzles 4 mounted on the universal delivery pipe 5 to achieve scouring at different angles. In the intertidal reef environment, the attachment positions of organisms such as oysters are often very complex. Some are attached to the surface of the reef, some to the side, and others are hidden in the crevices or depressions of the reef. Traditional tools struggle to effectively sample organisms in these complex locations, but the flexible bending characteristics of the universal delivery pipe 5 perfectly solve this problem. By adjusting the angle of the universal delivery pipe 5, the operator can precisely aim the nozzles 4 at organisms in different locations and with different attachment angles. Even organisms in reef crevices or depressions can be effectively scouring, greatly improving the comprehensiveness of sampling and ensuring that no target organism is missed.
[0047] Furthermore, a round shell 10 is installed at the end of the output pipe 2 9 away from the pressure control valve 8. A filter screen 18 is detachably installed inside the round shell 10. A threaded disc 20 is detachably installed on the round shell 10. A connecting pipe 19 is installed on the threaded disc 20. A hose 11 is connected to the end of the connecting pipe 19, and the hose 11 is connected to an external power source.
[0048] Pressure control valve 8 is a valve used in hydraulic systems to control liquid pressure. Its working principle is mainly based on the balance of forces. By sensing the pressure changes in the system, it uses the movement of the valve core to adjust the opening or closing of the fluid flow path, thereby achieving control of the system pressure.
[0049] As a preferred example of this utility model, a circular shell 10 is installed at the end of the output pipe 9 furthest from the pressure control valve 8. A filter screen 18, detachably mounted inside the shell, serves as a filter. The water pumped by the external pump may contain impurities, sand, or other particles. If these substances enter the output pipe and nozzle 4, they can easily clog the nozzle 4, affecting the normal spraying and flushing effect of the water. They can also cause wear on precision components such as the pressure control valve 8, shortening the lifespan of the device. The filter screen 18 effectively intercepts these impurities, ensuring the cleanliness of the water entering the water supply system. The detachably mounted threaded disc 20 on the circular shell 10 and the connecting pipe 19 mounted on the threaded disc 20 facilitate connection to the hose 11, ensuring a smooth water supply path. Furthermore, the detachable design of the threaded disc 20 makes regular cleaning or replacement of the filter screen 18 very convenient, ensuring that the filter screen 18 always maintains a good filtration effect and providing a reliable guarantee for the stable operation of the device.
[0050] Furthermore, a threaded groove 21 is provided at the end of the round shell 10 away from the output pipe 2 9. An installation groove 17 is provided on the inner wall of the threaded groove 21. The filter screen 18 can be detachably installed in the installation groove 17. The threaded disc 20 extends into the threaded groove 21 for threaded connection.
[0051] As a preferred example of this utility model, the threaded groove 21 at the end of the circular shell 10 furthest from the output pipe 9, connected to the threaded disc 20, offers advantages such as ease of operation and reliable connection. This connection method allows for very quick disassembly and installation of the threaded disc 20, enabling operators to easily open the circular shell 10 to replace or clean the internal filter screen 18, significantly reducing maintenance time. Simultaneously, the mounting groove 17 on the inner wall of the threaded groove 21 provides a stable mounting position for the filter screen 18, firmly securing it and preventing displacement or detachment under the impact of water flow, ensuring a stable and reliable filtration process. This further guarantees the normal operation of the device, allowing the filter screen 18 to continuously and effectively perform its filtration function, maintaining the smooth flow of the water supply system and the safety of all components.
[0052] In this embodiment, when sampling oysters on the reef is required, the operator first carefully observes the specific location where the oysters are attached to the reef. Whether it is on the flat surface, side, or hidden in crevices or depressions, the flexible characteristics of the universal delivery pipe 5 can accommodate the situation. The multiple annular grooves on the universal delivery pipe 5 allow it to be easily bent to the required angle. The operator only needs to adjust the degree of bending of the universal delivery pipe 5 according to the attachment position of the oysters to precisely adjust the nozzle 4 installed on the universal delivery pipe 5 to the appropriate rinsing position, ensuring that the nozzle 4 can accurately align with the gap between the oysters and the reef, laying the foundation for subsequent effective rinsing.
[0053] Next, the operator grips the handles 13 on the handrails 12 at the end of the mounting frame 2. The ergonomic design of the handles 13 makes the grip more comfortable and stable, while the handrails 12 provide solid support, allowing the operator to steadily control the entire device. By adjusting the force and angle of the handles 13, the device is brought close to the reef. At this point, the elastic arc plate 3 at the end of the mounting frame 2 utilizes its rubber elastic material to adapt to the shape of the reef surface, fitting tightly against the reef. This prevents washed-down oysters from falling off and also acts as a buffer when the device comes into contact with the reef, avoiding damage from a hard collision.
[0054] Subsequently, the operator connects one end of the hose 11 to the connecting pipe 19 of the threaded disc 20 on the circular shell 10, and the other end to an external water pump. After the connection is completed, the water pump is started, and water flows through the hose 11 into the connecting pipe 19, and then through the threaded disc 20 into the circular shell 10. The removable filter screen 18 inside the circular shell 10 immediately comes into play, filtering impurities, sand, and other particles in the water flow. If these impurities enter the subsequent water supply system, they can easily cause the nozzle 4 to become clogged or damage components such as the pressure control valve 8. The filtering effect of the filter screen 18 effectively ensures that the water flowing into the output pipeline is clean. The filter screen 18 is securely installed in the mounting groove 17 on the inner wall of the threaded groove 21 of the circular shell 10, and will not shift or fall off even under the impact of water flow, ensuring a stable and reliable filtration process. At the same time, the threaded connection between the threaded disc 20 and the threaded groove 21 of the circular shell 10 also facilitates the subsequent cleaning or replacement of the filter screen 18.
[0055] The filtered clean water flows from the round shell 10 into the output pipe 9. The output pipe 9 is fixed to the support plate 15 of the mounting bracket 2 by clamps 14 and 16 on the support plate 15. Clamps 14 and 16 are connected by bolts, firmly clamping the output pipe 9 and effectively preventing it from shaking due to impact force when the water flows inside the pipe, thus ensuring the stability of the water flow. The water continues to flow along the output pipe 9 and reaches the pressure control valve 8. The pressure control valve 8 is connected to the output pipe 9 and the output pipe 7 respectively by flanges at both ends. This connection method not only has good sealing performance and can effectively prevent water leakage and ensure stable water pressure, but also facilitates the replacement of pressure control valve 8 with different pressure ranges as needed. The operator can adjust the water pressure by adjusting the pressure control valve 8 according to the firmness of the oyster attachment. For loosely attached oysters, a lower pressure can be selected to avoid excessive scouring force that may damage the oyster shells; for tightly attached oysters, the pressure can be appropriately increased to ensure that the oysters can be peeled off the reef.
[0056] After pressure regulation, the water flow is delivered to connector 6 through output pipe 7. Multiple detachable universal delivery pipes 5 on the outside of connector 6 divert the water flow, which is then precisely sprayed out through nozzles 4 that have been pre-adjusted. The impact force of the water flow acts directly on the gaps between the oysters and the reef, quickly and effectively washing the oysters off the reef. The washed-off oysters, driven by gravity and the water flow, fall into the net 1 fixed to the lower end of the mounting frame 2 and the elastic arc plate 3. Because the elastic arc plate 3 fits tightly against the reef, the oysters will not leak out from the gaps, ensuring the integrity of the sampling. This method achieves higher efficiency than hammering and chiseling, less damage to the rock, and the ability to collect small individuals from the debris, while also being more convenient than hammering and chiseling in areas that are difficult to reach.
[0057] The embodiments of this application have been described above with reference to the accompanying drawings.

This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
