Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a pearl oyster breeding cage which is convenient for observing and recording the growth state. Background Technique

[0002] As a cultured object, pearl oysters need a suitable offshore environment to grow. In the breeding work of pearl oysters, a large number of breeding cages are required to provide a natural environment in the sea and frequently observe their growth conditions in order to change the breeding environment in time. However, traditional breeding cages need to erect support poles from the seabed to prevent the cages from being carried away by the waves. The support poles not only make it difficult to frequently pull out the cages from the seabed for observation, but also inconvenient to change the breeding position. Therefore, a pearl oyster breeding cage that is convenient for observing and recording the growth state is needed to improve the breeding rate.

[0003] Chinese Patent CN202941277U discloses a deep-water breeding cage for pearl oysters, which includes a square cage frame and a cage bottom frame placed on the bottom side of the cage frame. The four side surfaces, the upper surface and the lower surface of the cage frame are all covered with mesh sleeves. A suspension rope is connected to the top of the cage frame, and a number of floating balls are connected to the suspension rope. This solution locates on the sea surface through the floating balls, connects the cage frame with the floating balls through the suspension rope, and at the same time, the cage bottom frame arranged at the bottom of the cage frame can support the cage frame to prevent it from sinking into the seabed. Thus, this breeding cage for pearl oysters can be placed on the deep-sea bottom for breeding pearl oysters to save the cost of pearl oyster breeding. This utility model is used in the field of aquaculture.

[0004] The above solution still has several improvement points: the cage is inconvenient to pull up from the seabed and is not conducive to frequent observation; the height of the cage cannot be adjusted, and the best breeding environment cannot be provided. Content of the Utility Model

Detailed implementation mode

[0024] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0025] See Figures 1 to 6 ​​As shown in the figure, a pearl oyster farming cage for facilitating the observation and recording of growth status includes a floating platform 1 floating on the sea surface, a tray 5 sinking into the sea, and a cage bin 6 for loading pearl oysters. The floating platform 1 includes an anchor device 2 for preventing it from drifting away, a rope releasing device 3 for controlling the height of the tray 5, and floating arms 4 for increasing the load-bearing capacity of the floating platform 1. The anchor devices 2 are symmetrically installed on both sides of the floating platform 1, and the rope releasing devices 3 are symmetrically installed on both sides of the floating platform 1. The connecting lines of the spaces of the two anchor devices 2 and the spaces of the two rope releasing devices 3 are perpendicular to each other. The tray 5 is connected to the rope releasing device 3 and is located below the floating platform 1. The cage bin 6 is installed at the center of the upper surface of the tray 5. The floating arms 4 are installed in an annular array on the side of the floating platform 1 and are on the sea surface.

[0026] This farming cage loads a large number of pearl oysters through the cage bin 6. The cage bin 6 sinks into the sea together with the tray 5. The floating platform 1 marks the farming position and provides a platform for observation and recording at the same time. The anchor device 2 is used to position the floating platform 1 in the sea to prevent it from being blown away by the wind and waves. The height of the tray 5 in the sea is controlled through the rope releasing device 3. At the same time, the rope releasing device 3 also facilitates pulling up the tray 5 so that the staff can observe the pearl oysters in the cage bin 6 on the floating platform 1. Since the center of gravity of this farming cage shifts when the tray 5 is pulled up, it is easy for the floating platform 1 to sink into the sea. The floating arms 4 are used to additionally increase the buoyancy. At the same time, the swing of the floating arms 4 will offset part of the impact of the waves on the floating platform 1, ensuring that the tray 5 will not shake significantly along with the floating platform 1.

[0027] See Figure 1 and Figure 2 As shown in the figure, the anchor device 2 is provided with a hook lock 21, a positioning anchor 22, a first rotating shaft 23, and a rocker 24. One end of the hook lock 21 is wound around the anchor device 2, and the other end is installed with the positioning anchor 22. The positioning anchor 22 contacts the seabed. The first rotating shaft 23 passes through the anchor device 2, and the rocker 24 is installed at one end of the first rotating shaft 23.

[0028] The hook lock 21 is used to connect the positioning anchor 22. By throwing the positioning anchor 22 onto the seabed, the moving range of the floating platform 1 is restricted to prevent the floating platform 1 from drifting away. The first rotating shaft 23 is used to rotate the anchor device 2 to take in and release the hook lock 21. The rocker 24 is used to provide a rotating fulcrum. When the positioning anchor 22 is pulled up to fit against the lower surface of the floating platform 1, it is convenient to move the floating platform 1 in order to change the farming location.

[0029] See Figures 1 to 3 As shown in the figure, the rope releasing device 3 is provided with a pulling rope 31, a square joint 32, a second rotating shaft 33, and a knob 34. One end of the pulling rope 31 is wound around the rope releasing device 3, and the other end is connected with the square joint 32. The square joint 32 is connected to the upper surface of the tray 5. The second rotating shaft 33 passes through the rope releasing device 3, and the knob 34 is installed at one end of the second rotating shaft 33.

[0030] The pull rope 31 is used to connect the tray 5. The knob 34 provides a fulcrum for rotating the second rotating shaft 33. By changing the length of the pull rope 31, the height of the tray 5 in the sea can be controlled to select a more suitable sea layer for aquaculture activities. The square joint 32 is used to facilitate the installation and disassembly of the tray 5 from the pull rope 31 for the maintenance and replacement of the pull rope 31.

[0031] See Figure 3 and Figure 4 As shown, a brake disc 35, an annular hole 36, a brake lever 37 and a positioning platform 38 are arranged on the second rotating shaft 33. The brake disc 35 is installed at one end of the second rotating shaft 33 opposite to the knob 34. The annular holes 36 are arranged in an array on the brake disc 35. The positioning platform 38 is installed on the floating platform 1. The brake lever 37 is slidably installed on the positioning platform 38 and passes through the annular holes 36.

[0032] Since the tray 5 needs to adjust its height in the sea, in order to prevent the length of the pull rope 31 from changing due to the swaying of the rope release device 3 with the floating platform 1, the brake lever 37 is used to fix the brake disc 35, thereby locking the second rotating shaft 33. The positioning platform 38 provides a fulcrum for the installation of the brake lever 37. The size of the brake lever 37 corresponds to the size of the annular holes 36.

[0033] See Figure 4 As shown, a spring 371, a convex disc 372 and a fitting groove 373 are arranged on the brake lever 37. The convex disc 372 is installed on the brake lever 37. The fitting groove 373 is arranged at the center of the positioning platform 38. The spring 371 is installed between the convex disc 372 and the positioning platform 38.

[0034] The convex disc 372 provides a fulcrum for installing the spring 371. The brake lever 37 changes its own fixing condition for the brake lever 37 by squeezing the spring 371 and rotating in the fitting groove 373. When the second rotating shaft 33 needs to be rotated, the brake lever 37 needs to be first pulled out of the fitting groove 373 and rotated and fixed. When the second rotating shaft 33 needs to be fixed, the brake lever 37 is rotated again, and the spring 371 resets and inserts the brake lever 37 back into the annular hole 36.

[0035] See Figures 1 to 5 As shown, a side frame 43, a spherical joint 42 and a groove 41 are arranged on the floating arm 4. The side frames 43 are installed in an array on the side of the floating platform 1. The spherical joint 42 is installed at one end of the floating arm 4. The groove 41 is arranged at the other end of the floating arm 4.

[0036] The side frame 43 is used to install the floating arm 4. The sizes of the spherical joint 42 and the groove 41 correspond to each other, which facilitates the stacking of the floating arms 4 on the floating platform 1. Since the buoyancy increased by the floating arms 4 is fixed, the number of floating arms 4 is adjusted according to the weight of the pearl oysters installed.

[0037] See Figures 1 to 6As shown, the tray 5 includes an annular groove 51, an annular frame 52, a through hole 53 and a connecting platform 54. The annular groove 51 is provided on the upper surface of the tray 5. The annular frame 52 is installed at the center of the tray 5. The through hole 53 and the connecting platform 54 are cross - arranged on the tray 5.

[0038] The annular groove 51 is used to prevent the tray 5 from being subjected to excessive resistance when falling into the sea. The annular frame 52 is used to install the cage 6. The through hole 53 is used to facilitate hanging the tray 5 on the hook lock 21 to prevent the hook lock 21 from shaking and hitting the tray 5. The connecting platform 54 is used to connect the square joint 32.

[0039] See Figure 6 As shown, the connecting platform 54 is provided with a socket 541, a pin 542 and a nut 543. The socket 541 is provided at the center of the connecting platform 54. The pin 542 passes through the socket 541 from one side of the connecting platform 54, and the nut 543 is installed on the pin 542 and is on the other side of the connecting platform 54.

[0040] The connection between the tray 5 and the tow rope 31 is ensured by passing the pin 542 through the square joint 32 from the socket 541. The nut 543 is used to release the fixation of the pin 542, facilitating the removal of the tray 5 from the tow rope 31 for maintenance.

[0041] The above - mentioned embodiments only represent one or several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be understood as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
