Description

Technical Field

[0001] This utility model relates to the field of fishing equipment, and in particular to an aquaculture fishing equipment. Background Technology

[0002] Primarily used in marine and freshwater aquaculture, such as for fish, shrimp, and shellfish. Net cages and culture cages provide a controlled environment that promotes growth and reduces impact on wild populations. They maintain stable water quality, including temperature, pH, salinity (in seawater aquaculture), and oxygen levels, within a relatively enclosed environment. This helps reduce the impact of environmental fluctuations on aquatic organisms. Through careful design and management, net cages and culture cages can not only improve aquaculture yields and efficiency but also effectively protect the environment and promote sustainable development.

[0003] Existing aquaculture harvesting devices are designed to be difficult to disassemble, making cleaning and maintenance of the fish traps complex. The inside of the fish traps often accumulates dirt, algae, bacteria, or pathogens, which can not only deteriorate water quality but also pose health risks to farmed or harvested aquatic products. Accumulated pollutants can affect the normal operation of the equipment, such as reducing water flow velocity or affecting gas exchange efficiency, thereby impacting the growth environment and health of aquatic animals. Therefore, this paper proposes an aquaculture harvesting device to address these problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2This utility model provides an embodiment of an aquaculture harvesting device, comprising a base plate 1. The base plate 1 is the fundamental support component of the entire device, providing a stable bottom platform to support other components and equipment. The base plate 1 needs to be designed to be sufficiently robust to withstand the forces and loads generated during operation. Fixing blocks 24 are fixedly connected to both sides of the top of the base plate 1. These fixing blocks 24 are used to install and support other components, ensuring their stability during operation. The design of the fixing blocks 24 must ensure that they can reliably secure the connected components and withstand the forces generated during mechanical operation.

[0032] Two fixed blocks 24 are rotatably connected at their proximal ends to a drive assembly for driving the parts. This assembly is responsible for driving the movement of the device, including rotation and lifting functions. The drive assembly is designed to provide sufficient power and control precision to meet operational requirements. The other end of the drive assembly is fixedly connected to an upper shell 10, which protects the internal components and provides structural support. Its internal design allows for a sliding connection of a limiting post 12 and can accommodate and support other internal components. The limiting post 12 is slidably connected inside the upper shell 10. The limiting post 12 controls and limits the range of motion of the internal components. The sliding design of the limiting post 12 allows it to move freely within a set range while providing necessary support and stability.

[0033] A limiter 11 is slidably connected inside the limiting post 12. The limiter 11 is used to adjust and limit the sliding range to ensure precise operation of the device. Limiting blocks 13 are rotatably connected to both sides of the limiting post 12. The limiting blocks 13 are used to further limit and adjust the movement of the device to ensure its normal operation and prevent accidental damage. A spring 9 is fixedly connected to the top of the limiting post 12. The spring 9 provides elastic support, can buffer impact force, and maintain the stability of the device. A fixing plate 8 is fixedly connected to the top of the spring 9. The fixing plate 8 is fixedly connected to the inside of the upper shell 10 to provide support and positioning for other components of the device.

[0034] The outer side of the fixed plate 8 is fixedly connected to the inside of the upper shell 10. The lower shell 14 and the upper shell 10 together form the outer shell structure of the device, providing protection and stable support for the internal components. The outer side of the limiter 11 is slidably connected to the inside of the upper shell 10. The top of the upper shell 10 is slidably connected to the lower shell 14, and the outer side of the lower shell 14 is fixedly connected to a fishing assembly for catching aquatic products. The fishing assembly includes multiple fishing tools, such as a net structure or a clamping device, for catching aquatic products. The upper and lower ends of the base plate 1 are fixedly connected to moving assemblies for moving parts.

[0035] The movable components enable the device to be displaced and adjusted during operation, improving operational flexibility. A fixing assembly for securing parts is fixedly connected to the top of the base plate 1. This fixing assembly ensures that all parts of the device remain stable during operation, preventing displacement due to vibration or other factors. The drive assembly includes a motor 2, the bottom of which is fixedly connected to the top of the base plate 1 via a plate, providing power to the device. The selection of the motor 2 should consider its power, durability, and efficiency to meet drive requirements. A belt 3 is externally fitted to the drive end of the motor 2, transmitting the rotational motion of the motor 2 to the drum 4, ensuring stable and efficient power transmission.

[0036] The other end of the belt 3 is rotatably connected to a line drum 4, which stores and manages the fishing rope 5, supporting its smooth operation. The rope 5 is rotatably connected to the outside of the line drum 4. The rope 5 plays a crucial role in the fishing process, connecting the fishing assembly to the device's drive system. The fishing assembly includes multiple connecting ropes 15 and sliding rods 18. The proximal ends of the multiple connecting ropes 15 are fixedly connected to the outside of the lower shell 14, and the other ends are connected to multiple rotating plates 16. The sliding rods 18 provide vertical movement support and work in conjunction with the connecting ropes 15 to enhance the fishing effect. The proximal ends of the multiple connecting ropes 15 are fixedly connected to the outside of the lower shell 14.

[0037] Reference Figure 3 , Figure 4 The other end of the connecting rope 15 is fixedly connected to multiple rotating plates 16. A fishing net 26 is fixedly connected to the inner side of each rotating plate 16. The rotating plates 16, through their rotational motion, help the fishing device effectively catch aquatic products. Multiple holes are provided on the outer side of the sliding ring 19. These holes provide sliding support for the sliding rod 18 and allow for adjustment and operation of the fishing components. The design of the sliding ring 19 needs to ensure smooth sliding and durability. A fixed plate 17 is rotatably connected to the proximal ends of the multiple rotating plates 16. The fixed plate 17 is used to stabilize the structure of the rotating plates 16 and ensure the stability of the fishing process. Multiple sliding rings 19 are slidably connected to both the upper and lower ends of the sliding rod 18. Round-headed blocks 21 are fixedly connected to both sides of each sliding ring 19.

[0038] The rounded block 21 is used to improve the smoothness and wear resistance of sliding and prevent jamming during sliding. A fixing rod 20 is slidably connected inside the sliding ring 19. The fixing rod 20 is used to maintain stability during sliding and allows adjustment of the fishing assembly. The moving assembly includes a push handle 23, the bottom of which is fixedly connected to the top of the base plate 1. The push handle 23 allows the operator to easily push and move the device, improving operational convenience. Wheels 25 are fixed around the bottom of the base plate 1.

[0039] Wheels 25 enable the device to move easily in various working environments, enhancing its flexibility and operability. The fixing components include a bracket 7, the top of which is fixedly connected to two cable reels 26. The bracket 7 provides additional support and helps manage and store additional ropes 5. The bottom of the bracket 7 is fixedly connected to the top of a base plate 1, the top of which is slidably connected to multiple pointed posts 22. The pointed posts 22 provide additional stable support, preventing accidental movement or tilting of the device during operation.

[0040] Working principle: The operator can start the motor 2 to drive the belt 3 at its drive end. The back-and-forth rotation of the belt 3 controls the restriction of the line spool 4 on the rope 5, pulling the upper shell 10 and the cage out of the water. After the fish in the cage are emptied, the cage needs to be cleaned. This can be done by manually pulling the limiter 11, causing the limit post 12 to slide downwards. This causes the limit blocks 13 connected to both sides of the limit post 12 to rotate, causing the end of the limit block 13 away from the other side to tilt up. At this time, because the front end of the limiter 11 is set at an angle and the lower part of the limit post 12 is also set at an angle, it is exactly aligned with the limiter 11. The oblique angles fit together so that the limiting post 12 can be controlled by the control limiter 11. The two limiting blocks 13 are set in a lying E-shape. The interior of the lower shell 14 has protrusions to facilitate the locking of the limiting blocks 13. The middle position of the limiting block 13 is connected to both sides of the limiting post 12 by the rotation of the post. The limiting post 12 is inside the upper shell 10. So when the limiting post 12 slides down, the limiting block 13 will tilt to both sides due to the restriction of the upper shell 10. At this time, the lower shell 14 can be removed. Multiple connecting ropes 15 are fixedly connected to the top of the connecting ropes 15 so that the cage can be removed for cleaning. After the cage is removed, the sliding ring 19 connected to the sliding rod 18 can be slidably connected to it. The sliding ring 19 is fixed to the surface of the sliding rod 18 by the fixing rod 20. When the fixing rod 20 is removed, the sliding ring 19 can be slid. The round head blocks 21 fixedly connected to both sides of the sliding ring 19 control multiple rotating plates 16. The rotating plates 16 are connected to each other by the fixing plate 17, which is connected to the rotating plates 16 by the pillar. In this way, the entire cage can be folded by manually sliding multiple sliding rings 19 to facilitate storage and avoid taking up too much space.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
