Description

Technical Field

[0001] The utility model relates to the technical field of laver cultivation, in particular to a shallow sea semi-floating raft type laver yezoensis cultivation lifting device. Background Art

[0002] During the laver seedling and cultivation process, drying involves lifting the laver net above the water surface using a support or special device to keep it dry for a certain period of time. This operation not only promotes the healthy growth of the laver itself but also effectively prevents the occurrence of diseases. Laver is highly drought-tolerant, making drying a low-cost and effective disease control method. Drying can significantly inhibit the growth of harmful algae such as green algae and diatoms, reducing the risk of these algae competing with the laver for nutrients and light, while also reducing the growth of bacterial diseases and creating a more favorable environment for laver growth.

[0003] Currently, traditional semi-floating raft systems have limitations when it comes to drying in intertidal areas. This method relies on the natural receding of the tide; the laver curtains can only be exposed when the tide recedes completely. This limits the flexibility and efficiency of drying, especially in areas with erratic tides. Timely drying is difficult to ensure, hindering the healthy growth of laver.

[0033] like Figures 1 to 6 The shallow-water semi-floating raft type Porphyra yezoensis cultivation lifting device shown includes a raft frame 1, a net curtain 2 and a floating and sinking assembly 3 arranged thereon, and multiple floating and sinking assemblies 3 are arranged at the edge of the raft frame 1; the raft frame 1 includes a support column 11 and a mounting frame 12 arranged thereon, and the floating and sinking assembly 3 includes a connecting frame 31, a movable frame 32 and a buoy 33, and the buoy 33 is rotatably connected to the connecting frame 31 through the movable frame 32, and the connecting frame 31 is connected to the raft frame 1; the buoy 33 is located at the end of the movable frame 32 away from its rotation axis, and can swing between the upper and lower sides of the mounting frame 12 based on the rotation axis of the movable frame 32, and a locking assembly 4 is arranged between the connecting frame 31 and the movable frame 32.

[0034] In the specific implementation process, the floating and sinking components 3 arranged at the edge of the raft frame 1 enable the net curtain 2 to have two working states: dry and suspended; Figure 1 and Figure 2 The raft frame 1 shown is in a dry and exposed state. When the movable frame 32 flips toward the outside of the raft frame 1 and drives the buoy 33 thereon to rotate to the lower side of the raft frame 1, the movable frame 32 and the connecting frame 31 are locked by the locking assembly 4. After the tide rises, the buoyancy is provided by the buoy 33, so that the net curtain 2 is in a dry and exposed state. When the raft frame 1 is adjusted to a suspended state, the locking state of the locking assembly 4 is manually released, so that the movable frame 32 drives the buoy 33 thereon to rotate to the upper side of the raft frame 1 and float on the water surface. At this time, the movable frame 32 and the connecting frame 31 are locked by the locking assembly 4, so that the net curtain 2 is in a suspended state.

[0035] In the shallow-water semi-floating raft type laver aquaculture lifting device disclosed by the present invention, the raft frame 1 is the main structure of the device and is used to support and fix the laver net curtain 2. The net curtain 2 is fixed on the raft frame 1. The floating and sinking components 3 are rotated between the upper and lower sides of the raft frame 1 to realize the switching of the two working states of suspension and dry exposure, thereby improving the flexibility and efficiency of dry exposure. The buoys 33 in the floating and sinking components 3 can be selected according to the size of the raft frame 1 and the tidal flow rate to adapt to different aquaculture environments and conditions. When it is necessary to use a laver picking machine to pick laver, the movable frame 32 can be flipped upward and locked. The device has a simple structure, is easy to load and unload, is easy to operate, and is stable and reliable. It solves the limitations of the traditional "semi-floating raft type" structure in dry exposure operation and is suitable for shallow-water aquaculture areas.

[0036] In this embodiment, see further Figure 2 As shown, the mounting frame 12 is horizontally arranged and includes a cable 121 and a connecting rod 122 that are perpendicular to each other. The support column 11 is vertically arranged at the intersection of the cable 121 and the connecting rod 122; multiple support columns 11 are arranged in the length direction of the cable 121, and multiple connecting rods 122 are arranged parallel to the support columns 11. The two adjacent connecting rods 122 cooperate with the cables 121 at both ends of their length to form a rectangular frame 123, and the net curtain 2 is arranged in the frame 123.

[0037] The raft frame 1 is composed of support columns 11 and mounting frames 12. The mounting frames 12 form a stable rectangular frame 123 structure through mutually perpendicular cables 121 and connecting rods 122. The support columns 11 are vertically arranged at the intersection of the cables 121 and connecting rods 122 to provide sufficient support. Figure 1 As shown, multiple parallel connecting rods 122 cooperate with cables 121 to form multiple frames 123 to install multiple net curtains 2, and the corresponding multiple supporting columns 11 can ensure the stability and bearing capacity of the entire raft 1 structure.

[0038] In this embodiment, if Figure 3As shown, the connecting frame 31 includes a fixed seat 311 and a rotating shaft seat 312 and a connecting cantilever 313 arranged thereon. The fixed seat 311 is arranged vertically, the rotating shaft seat 312 is located in the middle of the fixed seat 311, and the connecting cantilever 313 is located at the top of the fixed seat 311, and two are symmetrically arranged.

[0039] Furthermore, the fixed seat 311 is connected to the support column 11 through a clamp 314, the two connecting cantilevers 313 are respectively connected to the cables 121 on both sides of the support column 11, the movable frame 32 is rotatably connected to the fixed seat 311 through a rotating shaft seat 312, and the float 33 is set at the bottom of the movable frame 32.

[0040] The connecting seat is connected to the horizontally arranged cable 121 through two connecting cantilevers 313, which limits the vertical movement of the connecting frame 31. The connecting seat is further connected to the vertically arranged support column 11 through a clamp 314, which limits the horizontal movement of the connecting frame 31 and the rotation relative to the cable 121; the connecting frame 31 is connected to the raft frame 1 through a three-point connection method to ensure the stability of the connection. The connection method is not only simple and efficient, but also can ensure uniform force on the connection point, further improving the stability and reliability of the entire system.

[0042] The locking mechanisms 41 relatively arranged on the upper and lower sides of the rotating shaft seat 312 can realize the locking and positioning of the movable frame 32 after being flipped to the upper and lower sides of the raft frame 1, thereby providing the net curtain 2 with two stable working states of dry and suspended.

[0043] See Figure 5 and Figure 6 As shown, the locking mechanism 41 includes a support 414 arranged on the side of the fixed seat 311 facing away from the movable frame 32, and a pin 412 arranged on the support 414, the root of the pin 412 is located above the support 414, and a return spring 413 is provided between the root of the pin 412 and the support 414; it also includes a socket 411 opened on the fixed seat 311, the pin 412 is located at one end of the socket 411 and is arranged perpendicular to it, an annular groove 421 is opened on the pin 42 corresponding to the pin 412, and a mounting hole 321 is provided on the movable frame 32 corresponding to the pin 42.

[0044] Furthermore, a slope 412a is provided on the head of the staple 412, and the slope 412a is provided toward the insertion hole 411; a conical surface 422 is provided at one end of the pin 411 corresponding to the staple 412, and an elastic washer 423 is provided on the other end, and a pull rope 424 is provided on the elastic washer 423.

[0045] In the specific implementation process, when the movable frame 32 is flipped upward or downward to fit with the fixed seat 311, the latch 42 passes through the mounting hole 321 on the movable frame 32 and is inserted into the insertion hole 411. During the process, the clamping pin 412 is lifted up after being forced by the inclined surface 412a. After the latch 42 is further inserted, the clamping pin 412 is clamped into the annular groove 421 of the latch 42 under the action of the return spring 413, thereby locking the latch 42 in position.

[0046] When the locking state between the movable frame 32 and the fixed seat 311 needs to be released, the pin 412 is manually pulled out of the ring groove to release the lock on the latch 42; the latch 42 is then pulled out of the socket 411 to complete the release of the locking state between the movable frame 32 and the fixed seat 311. A pull rope 424 is provided on the elastic washer 423 to facilitate the removal of the latch 42 and prevent it from being lost after falling. Similarly, a pull rope can also be provided at the base of the pin 412, which can be used to simultaneously pull the pins 412 on multiple fixed seats 311 to release the lock of the latch 42.
