Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a circular ring oyster scraper. Background Technology

[0002] Marine aquaculture refers to the production activities of cultivating marine aquatic economic plants and animals using shallow sea beaches and tidal flats along the coast, including various forms such as shallow sea aquaculture, tidal flat aquaculture, and harbor aquaculture. With the continuous development of aquaculture, new aquaculture methods and technologies are constantly emerging, among which pole-planting aquaculture is a relatively common method.

[0003] When using pole-planting aquaculture, bamboo poles or fiberglass supports are used. Impurities and biological deposits will adhere to the poles, requiring workers to clean them regularly. This results in high labor intensity and poor cleaning effectiveness, affecting the lifespan of the poles. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing a circular ring scraper that can solve the problem of the inconvenience of cleaning impurities and biological deposits on the oyster rod, which affects the service life of the oyster rod.

[0005] The technical solution of this utility model is as follows: A circular ring oyster scraper includes at least two scraper bodies and a connecting assembly. Each scraper body includes a first buoyancy plate and a second buoyancy plate. The first buoyancy plate and the second buoyancy plate are joined together to form a circular buoyancy plate. A pair of first scrapers are fixedly connected to the inner sidewalls of the first buoyancy plate and the second buoyancy plate. Multiple second scrapers are fixedly connected to the inner sidewalls of the first buoyancy plate and the second buoyancy plate. The pair of first scrapers are respectively disposed on the upper and lower sides of the multiple second scrapers. Multiple pushing blocks are integrally formed on the outer sidewalls of the first buoyancy plate and the second buoyancy plate. The connecting assembly includes a connecting rod, which is installed between the multiple scraper bodies.

[0006] The above technical solution involves assembling the oyster scraper body using a first buoyancy plate and a second buoyancy plate. This allows the scraper body to be easily fitted onto the rod during installation, facilitating easy assembly and disassembly. When the first and second buoyancy plates move up and down in a floating state, they move the first scraper, which cleans impurities and biological deposits from the rod. When the water flow causes the first and second buoyancy plates to rotate, it rotates the second scraper, which also cleans impurities and biological deposits from the rod. The scraper can be used for efficient cleaning. By setting multiple push blocks, when the water flow impacts the stepped surface of the push blocks, the scraper body can be rotated by the water flow. The rotation of the scraper body can clean the rod. Multiple scraper bodies are connected together by connecting rods. The ring scraper composed of multiple scraper bodies can move up and down and rotate under the influence of buoyancy and water flow impact when the water flow changes. This causes the first scraper and the second scraper to move. The first scraper and the second scraper can then clean the impurities and biological attachments on the rod.

[0007] A further feature of this invention is that a pair of first scrapers are symmetrically arranged at the upper and lower ends of the first buoyancy plate and the second buoyancy plate, and the included angle between the first scraper and the inner sidewall of the first buoyancy plate and the second buoyancy plate is set to 45 degrees.

[0008] With the above-mentioned further configuration, when the oyster scraper body moves up and down under the action of buoyancy, the first scraper at both the upper and lower ends can clean the rod. At the same time, the first scraper is set at a 45-degree angle, which makes the cleaning effect of the first scraper on the rod better.

[0009] A further feature of this invention is that the second scraper is V-shaped, with the two ends of the opening of the second scraper serving as scraping ends.

[0010] With the above-mentioned further design, the V-shaped scraper end ensures that the second scraper can clean the rod body regardless of whether the scraper body rotates forward or backward under the impact of water flow.

[0011] A further improvement of this invention is that the pushing block is arranged in a trapezoidal shape, and one end of the small end of the pushing block is integrally formed with the buoyancy plate.

[0012] By adopting the above-mentioned further settings, when the water flow impacts the stepped surface of the push block, the water flow changes and impacts different stepped surfaces of the push block, so that the oyster scraper body can rotate forward and backward with the change of water flow.

[0013] A further feature of this invention is that the first buoyancy plate and the second buoyancy plate are integrally formed with a first connecting ear and a second connecting ear at both ends, and the corresponding first connecting ear and second connecting ear are connected to each other when the first buoyancy plate and the second buoyancy plate are docked.

[0014] The above-mentioned further design facilitates the installation between the two buoyancy plates.

[0015] A further feature of this invention is that a snap-fit ​​block is fixedly connected to the outer side wall of the first connecting ear on the first buoyancy plate and the second connecting ear on the second buoyancy plate. A snap-fit ​​groove is provided on the outer side wall of the second connecting ear on the first buoyancy plate and the first connecting ear on the second buoyancy plate. When the first buoyancy plate and the second buoyancy plate are connected, the snap-fit ​​block is slidably connected in the corresponding snap-fit ​​groove.

[0016] By adopting the above-mentioned further configuration, through the cooperation of the snap-fit ​​block and snap-fit ​​groove, the first buoyancy plate and the second buoyancy plate are stable after assembly, and are easy to disassemble and assemble with each other.

[0017] A further feature of this invention is that both the first connecting ear and the second connecting ear are provided with mounting holes, and when the first buoyancy plate and the second buoyancy plate are connected, fixing screws are respectively installed on the first connecting ear and the second connecting ear through the mounting holes.

[0018] With the above-mentioned further configuration, the first buoyancy plate and the second buoyancy plate can be fixed together by fixing screws, so that the first buoyancy plate and the second buoyancy plate are stable after assembly.

[0019] A further feature of this invention is that threaded holes are provided on the side walls of the first buoyancy plate and the second buoyancy plate in a vertically penetrating manner, and the upper and lower ends of the connecting rod are respectively threaded into the corresponding threaded holes.

[0020] By further modifying the above-mentioned design, the connecting rod is installed in the screw hole via a threaded connection, allowing multiple oyster scraper bodies to be connected together. The threaded connection also facilitates the assembly and disassembly of the multiple oyster scraper bodies.

[0021] A further improvement of this invention is that both the oyster scraper body and the connecting components are made of hard plastic with good corrosion resistance.

[0022] By adopting the above-mentioned further design, the oyster scraper has good buoyancy and will not be corroded in water, thereby improving the service life of the oyster scraper. Attached Figure Description

[0032] like Figure 1-4As shown, a circular ring oyster scraper includes at least two scraper bodies 1 and a connecting assembly 2. Multiple scraper bodies 1 are assembled to form a scraper that is fitted onto a rod. When it moves up and down under buoyancy, it scrapes away impurities and biological attachments on the rod. Each scraper body 1 includes a first buoyancy plate 11 and a second buoyancy plate 12, which are joined together to form a circular buoyancy plate. The scraper body 1 is assembled using the first buoyancy plate 11 and the second buoyancy plate 12, making it easy to fit onto the rod during installation and facilitating assembly and disassembly. A pair of first scrapers 13 are fixedly connected to the inner walls of both the first buoyancy plate 11 and the second buoyancy plate 12. When the first buoyancy plate 11 and the second buoyancy plate 12 move up and down under buoyancy, they move the first scrapers 13, which then clean the impurities and oysters on the rod. Multiple second scrapers 14 are fixedly connected to the inner walls of the first buoyancy plate 11 and the second buoyancy plate 12. When the water flow impacts and causes the first buoyancy plate 11 and the second buoyancy plate 12 to rotate, the second scrapers 14 can be rotated to clean impurities and oysters on the rod. A pair of first scrapers 13 are respectively arranged on the upper and lower sides of the multiple second scrapers 14. The cooperation of the first scrapers 13 and the second scrapers 14 can efficiently clean impurities and oysters on the rod. Multiple pushing blocks 15 are integrally formed on the outer walls of the first buoyancy plate 11 and the second buoyancy plate 12. By setting multiple pushing blocks 15, when the water flow impacts the stepped surface of the pushing blocks 15, the water flow can cause the oyster scraper body 1 to rotate, thereby cleaning the rod through the rotation of the oyster scraper body 1.

[0033] like Figure 1 and Figure 2 As shown, the connecting component 2 includes a connecting rod 21, which is installed between multiple oyster scraper bodies 1. The multiple oyster scraper bodies 1 are connected together by the connecting rod 21, so that the annular oyster scraper composed of multiple oyster scraper bodies 1 can move the first scraper 13 and the second scraper 14 by floating up and down and rotating under the influence of buoyancy and water flow when the water flow changes. Thus, the first scraper 13 and the second scraper 14 can be used to clean impurities and oysters on the rod body.

[0034] Preferably, both the oyster scraper body 1 and the connecting component 2 are made of hard plastic with good corrosion resistance, which makes the oyster scraper have good buoyancy and will not be corroded in water, thereby improving the service life of the oyster scraper.

[0035] like Figure 3 and Figure 4As shown, a pair of first scrapers 13 are symmetrically arranged at the upper and lower ends of the first buoyancy plate 11 and the second buoyancy plate 12, and the angle between the first scraper 13 and the inner sidewalls of the first buoyancy plate 11 and the second buoyancy plate 12 is set at 45 degrees. This allows the scraper body 1 to clean the rod body when it moves up and down under the action of buoyancy, as the first scrapers 13 at both ends can clean the rod body. At the same time, the first scrapers 13 are inclined at a 45-degree angle, which makes the cleaning effect of the first scrapers 13 on the rod body better.

[0036] like Figure 3 and Figure 4 As shown, the second scraper 14 is V-shaped, and the two ends of the opening of the second scraper 14 are scraping ends. Through the V-shaped scraping ends, the second scraper 14 can clean the rod body regardless of whether the scraper body 1 rotates forward or backward under the impact of the water flow.

[0037] like Figure 1 and Figure 4 As shown, the push block 15 is configured as a trapezoidal block. The larger end of the push block 15 is positioned away from the buoyancy plate and the outer wall of the first scraper 13, while the smaller end of the push block 15 is integrally formed with the buoyancy plate. This allows the water flow to impact different stepped surfaces of the push block 15 when the water flow direction changes. This enables the oyster scraper body 1 to rotate in both directions with the change of water flow direction, thus ensuring that the change of water flow direction does not affect the oyster scraper body 1 and improving its practicality.

[0038] like Figure 4 As shown, the first buoyancy plate 11 and the second buoyancy plate 12 are integrally formed with a first connecting ear 16 and a second connecting ear 17 at both ends, respectively. When the first buoyancy plate 11 and the second buoyancy plate 12 are connected, the corresponding first connecting ear 16 and second connecting ear 17 are connected to each other.

[0039] like Figure 4 As shown, snap-fit ​​blocks 18 are fixedly connected to the outer walls of the first connecting ear 16 on the first buoyancy plate 11 and the second connecting ear 17 on the second buoyancy plate 12. Snap-fit ​​grooves 19 are formed on the outer walls of the second connecting ear 17 on the first buoyancy plate 11 and the first connecting ear 16 on the second buoyancy plate 12. When the first buoyancy plate 11 and the second buoyancy plate 12 are joined, the snap-fit ​​blocks 18 slide within the corresponding snap-fit ​​grooves 19. Through the cooperation of the snap-fit ​​blocks 18 and the snap-fit ​​grooves 19, the first buoyancy plate 11 and the second buoyancy plate 12 are stable after assembly, while also facilitating easy assembly and disassembly.

[0040] like Figure 4As shown, both the first connecting ear 16 and the second connecting ear 17 are provided with mounting holes 110. When the first buoyancy plate 11 and the second buoyancy plate 12 are connected, fixing screws 111 are installed on the first connecting ear 16 and the second connecting ear 17 through the mounting holes 110 respectively. The fixing screws 111 can fix the first buoyancy plate 11 and the second buoyancy plate 12 together, so that the first buoyancy plate 11 and the second buoyancy plate 12 are stable after assembly.

[0041] like Figure 2 Combination Figure 3 As shown, threaded holes 22 are formed on the side walls of the first buoyancy plate 11 and the second buoyancy plate 12 in a vertically penetrating manner. The upper and lower ends of the connecting rod 21 are respectively threaded into the corresponding threaded holes 22. By installing the connecting rod 21 into the threaded holes 22 through the threaded connection, multiple oyster scraper bodies 1 can be connected together through the connecting rod 21. At the same time, the threaded connection makes it easy to assemble and disassemble the multiple oyster scraper bodies 1. Furthermore, the length of the threaded holes 22 can be adjusted according to specific needs, improving the practicality of the oyster scraper.

[0042] Optionally, at least two oyster scraper bodies 1 can be provided. The number of oyster scraper bodies 1 can be selected according to the length of the rod during installation, which improves the practicality of the oyster scraper.

[0043] In use, the first buoyancy plate 11 and the second buoyancy plate 12 are fitted onto the rod body and joined together. When the first buoyancy plate 11 and the second buoyancy plate 12 are joined together, the locking block 18 is slidably connected into the corresponding locking groove 19. Thus, the first buoyancy plate 11 and the second buoyancy plate 12 can be stably joined together through the cooperation of the locking block 18 and the locking groove 19. Then, the structure of the oyster scraper body 1 composed of the first buoyancy plate 11 and the second buoyancy plate 12 is stabilized by tightening the fixing screw 111, thus completing the connection on the rod body. After the oyster scraper bodies 1 are connected, the connecting rod 21 is threaded into the screw hole 22 on the first buoyancy plate 11 and the second buoyancy plate 12. Multiple oyster scraper bodies 1 can then be connected together to form an oyster scraper. When in use, the oyster scraper will float up and down or rotate with the changes in water flow. When the oyster scraper floats or rotates, it can drive the first scraper 13 and the second scraper 14 to move, thereby cleaning the impurities and biological attachments on the rod body through the first scraper 13 and the second scraper 14.
