Description

Technical Field

[0001] The invention relates to a wave energy linked shellfish grinding and cultivating device, belonging to the technical field of seafood cultivation. Background Art

[0002] With the continuous increase in market demand for seafood, my country's seafood aquaculture industry is developing continuously, especially the aquaculture of shellfish is developing more rapidly, and the aquaculture of shellfish is inseparable from the cage. In the field of marine shellfish aquaculture, the fixed structure and passive rotation mode of traditional cages can no longer meet the needs of modern aquaculture. In the existing technology, the cage is usually fixed to the seabed by steel cables or anchoring devices, and its rotation state is completely dependent on natural forces such as waves and tides. However, this type of design has significant defects: First, under severe sea conditions, the cage is prone to violent shaking or even overturning due to external force impact, causing shellfish to be damaged or escape due to collision, resulting in economic losses; second, under normal sea conditions with calm winds and waves, the cage falls into a static state due to the lack of continuous power input, and cannot simulate the natural water flow environment, resulting in reduced shellfish feeding efficiency and accumulation of attachments on the shell surface, seriously affecting the growth rate and quality of the finished product.

[0003] Research has shown that shellfish, when exposed to moderate currents, can naturally polish themselves through friction between their shells and the water, thereby enhancing their value (e.g., the glossiness of oysters and the closing force of scallops). However, the passive rotation mechanism of traditional cages is only effective within a specific range of wave intensities. When wave energy is insufficient (e.g., in shallow coastal waters or during summer advection), shellfish are exposed to prolonged periods of still water, prone to growth stagnation and frequent disease. Therefore, we have developed an improved, wave-powered shellfish polishing and aquaculture device. Summary of the Invention

[0004] To address the challenges of existing technologies, the present invention provides a wave-powered shellfish grinding and aquaculture device. Through its drive mechanism and cage structure, the device enables the cage to rotate automatically in quiet, less turbulent conditions. This allows the seafood inside to move with the cage's rotation, harnessing the power of the waves to polish the shellfish, enhancing their quality. Furthermore, the rotation promotes water exchange between the inside and outside, increasing dissolved oxygen levels and improving the aquaculture environment.

[0005] The technical solution adopted by the present invention is a wave energy-linked shellfish grinding and cultivation device, which includes two brackets, one of which is provided with a driving mechanism, and an active side transmission device and a driven side transmission device are respectively installed on the two brackets. The other ends of the active side transmission device and the driven side transmission device are connected to the net cage, and the driving mechanism drives the net cage to rotate through the active side transmission device.

[0007] As a further solution of the present invention, the active side transmission device includes a connecting frame and a gear transmission assembly. A transmission rod is provided in the connecting frame, and the gear transmission assemblies are respectively installed at both ends of the connecting frame and connected to the transmission rod.

[0008] As a further solution of the present invention, the gear transmission assembly includes a buckle cover, a transmission shaft, a first bevel gear, a second bevel gear, and a transmission bearing. The transmission shaft passes through the buckle cover, the transmission bearing is sleeved on the outer periphery of the transmission shaft, the first bevel gear is sleeved on the outer periphery of the transmission shaft, the second bevel gear is sleeved on the transmission rod, and the first bevel gear and the second bevel gear are engaged for transmission.

The partition is installed on the inner side of the frame and divides the frame into several breeding spaces. The net is fixed on the outer periphery of the frame.

[0024] In order to further understand the content of the present invention, this technical solution is further described below in conjunction with specific implementation methods.

[0025] Example 1: Figures 1 to 7 As shown, this embodiment provides a wave energy-linked shellfish grinding and cultivation device, including brackets 1 fixed on both sides of an offshore platform 5, wherein a driving mechanism is provided on one of the brackets 1, and an active side transmission device 2 and a driven side transmission device 3 are respectively installed on the two brackets 1, and the other ends of the active side transmission device 2 and the driven side transmission device 3 are connected to a net cage 4, and the driving mechanism drives the net cage 4 to rotate through the active side transmission device 2.

[0026] As a specific implementation of this embodiment, the active-side transmission device 2 includes a connecting frame 20 and a gear transmission assembly. A transmission rod 21 is provided in the connecting frame 20. The gear transmission assembly is mounted on both ends of the connecting frame 20 and connected to the transmission rod 21. The gear transmission assembly includes a buckle cover 22, a transmission shaft 23, a first bevel gear 24, a second bevel gear 25, and a transmission bearing 26. The transmission shaft 23 passes through the buckle cover 22. The transmission bearing 26 is sleeved on the outer circumference of the transmission shaft 23. The first bevel gear 24 is sleeved on the outer circumference of the transmission shaft 23. The second bevel gear 25 is sleeved on the transmission rod 21. The first bevel gear 24 and the second bevel gear 25 are meshed and transmitted.

[0027] As a specific implementation of this embodiment, the driven side transmission device 3 includes a mounting frame 30, a connecting member 31, a driven bearing 32, an end cover 33, and a rotating shaft 34, wherein the connecting member 31 is fixed to one end of the mounting frame 30, the rotating shaft 34 passes through the connecting member 31, the driven bearing 32 is sleeved on the outer periphery of the rotating shaft 34, and the end cover 33 is buckled on the driven bearing 32.

[0028] As a specific implementation of this embodiment, the net cage 4 includes a frame 40, a mesh 41, a support shaft 42, and partitions 43. The partitions 43 are mounted inside the frame 40 and divide the frame 40 into several breeding spaces. The mesh 41 is fixed to the outer periphery of the frame 40. The support shaft 42 extends through the axis of the frame 40. Under the action of force, the net cage 4 can rotate about the support shaft 42. One of the transmission shafts 23 of the active-side transmission device 2 and one of the rotating shafts 34 of the driven-side transmission device 3 are respectively connected to the ends of the support shaft 42.

[0029] The driving mechanism controls the transmission shaft 23 to rotate, thereby driving the first bevel gear 24 and the second bevel gear 25 to rotate. The second bevel gear 25 transmits power to the transmission shaft 23 through the transmission rod 21. The transmission shaft 23 is connected to the mesh cage 4, so that the mesh cage 4 rotates with the support shaft 42 as the axis.

[0030] Example 2: Figures 1 to 7 As shown, based on Example 1, as a specific implementation of this embodiment, the drive mechanism includes a drive motor 11 mounted on a bracket 1 via a fixing bracket 10. The output end of the drive motor 11 is connected to a transmission shaft 23 of the active-side transmission device 2. The transmission shaft 23 is provided with a sprocket 27, and adjacent sprockets 27 are connected by a chain 28. Thus, one drive motor 11 drives multiple cages 4 to rotate.

[0031] like Figures 1 to 7As shown in Example 2, the seafood in the cage 4 is scallops. The active-side transmission device 2 and the passive-side transmission device 3 are respectively mounted on the bracket 1. The rotating shaft 34 of the passive-side transmission device 3 is concentric with the transmission shaft 23 of the active-side transmission device 2. The support shafts 42 on both sides of the cage 4 are respectively fixed to the transmission shaft 23 of the active-side transmission device 2 and the rotating shaft 34 of the passive-side transmission device 3. The upper transmission shaft 23 of the active-side transmission device 2 is mounted with a sprocket 27. Adjacent sprockets 27 are alternately connected by a chain 28. This allows a single drive motor 11 to drive the transmission shaft 23, thereby driving the rotation of the cage 4. This allows the rotation of the cage 4 to be controlled when the sea waves are relatively small, making the quality of the shellfish more controllable. The mechanical control of the movement of the cage 4 and the scouring of the waves can improve the quality of the shellfish.
