Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0043] Unless otherwise defined, all the technical and scientific terms used in the present application have the same meanings as those commonly understood by the person skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The term "and / or" used in the present application includes any and all combinations of one or more related listed items.

[0044] As Figures 1 to 6As shown, a deep-sea full-floating raft type Porphyra yezoensis cultivation automatic lifting device, comprising:

[0045] The Porphyra yezoensis cultivation raft frame 1 provides a support surface for the Porphyra yezoensis net curtain 11 to support the Porphyra yezoensis; the raft frame is usually composed of a plurality of buoyancy materials, which can ensure that the entire structure floats on the water surface and will not sink into the water due to the weight of the Porphyra yezoensis on the net curtain; the Porphyra yezoensis is placed on the Porphyra yezoensis net curtain 11 for cultivation, and when the Porphyra yezoensis is mature, it is convenient to use the harvesting machine for harvesting operation;

[0046] The lifting system 3 comprises a rotating support part 32 and a float 31 fixedly connected with the rotating support part 32, and the rotating support part 32 is rotatably connected with the Porphyra yezoensis net curtain 11 to switch the position of the float 31 relative to the Porphyra yezoensis net curtain 11;

[0047] The float 31 can be in the form of a rigid high-density floating ball or a flexible high-density inflatable float 31, and the material can be a high-pressure, wear-resistant, corrosion-resistant high polymer material or a composite material; in addition to the traditional spherical and cylindrical shapes, the float 31 can also be designed in the shape of a circular arc, an inflatable type, and a flexible float 31; when the inflatable type and the flexible float 31 are used, the float 31 can be designed to be inflated after being locked to solve the problem of insufficient rotational torque of the pneumatic motor 21;

[0048] With the switching of the relative position of the float 31, the influence of the buoyancy of the float 31 on the Porphyra yezoensis net curtain 11 also changes, thereby achieving the purpose of adjusting the working mode switching of the Porphyra yezoensis net curtain 11 lifting driving device, such as Figure 1 and Figure 2 As shown, there are two different working modes;

[0049] The high-pressure gas driving system 2 is connected with the rotating support part 32 to provide rotating power for the rotating support part 32, thereby driving the change of the position of the float 31 relative to the Porphyra yezoensis net curtain 11;

[0050] The external supporting equipment 5 is connected with the high-pressure gas driving system 2 and is used for inputting external compressed air to the high-pressure gas driving system 2;

[0051] The control system 4 is arranged on the lifting system 3 and is used for controlling the high-pressure gas driving system 2 and the lifting system 3.

[0052] The high-pressure gas driving system 2 comprises:

[0053] The driving gear set 22 is connected with the lifting system 3 at the output end; the gear at the output end can be selected to be a bidirectional ratchet type, and the tooth shape design of the bidirectional ratchet type enables it to play a role of one-way locking in both directions; one side of each tooth has a slope, and the other side also has a slope, but the directions are opposite; so that the rotating support 32b can rotate freely when the pneumatic motor 21 rotates in the forward or reverse direction;

[0054] A pneumatic motor 21, one end of which is connected to the input end of the drive gear set 22, and the other end of which is connected to the external matching device 5, is driven to rotate by the external compressed air supplied by the external matching device 5; when the pneumatic motor 21 is working, compressed air is introduced through the air inlet, the pressure energy of the compressed air is converted into mechanical energy to drive the internal rotor to rotate and output rotation, and then the exhaust port is used to exhaust;

[0055] In some embodiments, the speed and torque can be adjusted to match the load by installing an operating valve such as a flow regulating valve or a pressure reducing valve on the air inlet pipeline and cooperating with the drive gear set 22; preferably, the pneumatic motor 21 and the drive gear set 22 can be integrated into one, which is arranged in the rotating support part 32, so that the occupied space is smaller, and the arrangement in the interior can better prevent seawater erosion.

[0056] The rotating support part 32 comprises:

[0057] The fixed base 32a is horizontally fixedly connected with the seaweed cultivation raft 1; it is used for supporting the whole device; in this way, the lifting system 3 is avoided from directly contacting the seaweed net curtain 11, the influence on seaweed collection is prevented, and enough space is left for switching the working mode;

[0058] The rotating support 32b comprises a rotating shaft 32b1, the rotating shaft 32b1 is arranged through the fixed base 32a, and the rotating shaft 32b1 is in transmission connection with the output end of the drive gear set 22; the rotating support 32b is fixedly connected with the rotating shaft 32b1; the power transmitted to the rotating shaft 32b1 by the drive gear set 22 drives the rotation of the rotating support 32b, and finally drives the movement of the float 31, and switches the relative position of the float 31 relative to the net curtain;

[0059] The float fixing seat 32c is installed on the rotating support 32b and away from one end of the rotating shaft 32b1, and is used for fixing the float 31;

[0060] The rotating range of the rotating support 32b is that the float 31 is driven to be above the seaweed cultivation raft 1, to below the seaweed cultivation raft 1 on the side of the seaweed cultivation raft 1, and can form a rotating range of at most 270 degrees.

[0061] Preferably, the control system 4 comprises;

[0062] The locking mechanism 41 comprises a clamping module 41a and a clamping piece 41b, the clamping module 41a is installed on the fixed base 32a; the clamping piece 41b is installed on the rotating support 32b; when the float 31 is rotated to below the seaweed net curtain 11 along with the rotating support 32b, the clamping module 41a is clamped into the clamping piece 41b, so that the rotating support 32b is locked;

[0063] A passive magnetically controlled air valve 42 is mounted on the fixed base 32a and is used to control the operation of the air motor 21;

[0064] The unlocking mechanism 43 is connected to the locking mechanism 41 and drives the locking mechanism 41 to release the rotating bracket 32 ​​b.

[0065] The working modes are divided into dry mode and suspension mode;

[0066] like Figure 3 As shown, when the laver is to be dried, the control mechanism controls the high-pressure gas drive system 2 to start air intake, so that the pneumatic motor 21 drives the drive gear set 22, and the rotating support part 32 is driven by the drive gear set 22, thereby driving the rotation of the rotating bracket 32b, and the float 31 rotates to the bottom of the side of the laver cultivation raft 1. The locking mechanism 41 locks the rotating bracket 32b, and the high-pressure gas drive system 2 stops air intake; the buoyancy brought by the float 31 causes the laver net curtain 11 to rise to completely float out of the water, so that the device is in the drying mode at this time, preventing laver diseases, inhibiting the growth of algae such as green algae and diatoms, and inhibiting the occurrence of bacteria and viruses, thereby achieving the effect of improving the survival rate and quality of laver;

[0067] like Figure 4 As shown, the unlocking mechanism 43 pushes the clamping module 41a in the locking mechanism 41 to disengage the clamping member 41b, thereby releasing the rotating bracket 32b, and the pneumatic motor 21 drives the driving gear set 22, thereby driving the reverse rotation of the rotating bracket 32b, so that the float 31 rotates to above the laver cultivation raft 1, and the buoyancy brought by the float 31 cannot drive the laver net curtain 11 to rise to the surface of the water, and the laver net curtain 11 is submerged in water, so that the device is in suspension mode at this time.

[0068] When the device is in the drying mode, preferably, in the vertical direction, the float 31 is designed to be located at one end of the rotating bracket 32b close to the center point of the laver cultivation raft 1, so as to achieve the effect of lifting the net curtain from the bottom by buoyancy, and drying the laver more stably as a whole.

[0069] The rotating bracket 32b is divided into a short arm 32b2 and a long arm 32b3. The short arm 32b2 is connected to the rotating shaft 32b1, and one end of the long arm 32b3 is connected to the short arm 32b2 and the other end is connected to the buoy fixing seat 32c, forming a curved arm shape. This can improve the position of the rotating shaft 32b1 installed on the fixed base 32a, so that there is more space to install components such as the pneumatic motor 21, reducing the harm caused by being immersed in seawater; the length of the short arm 32b2 is less than the length from the rotating shaft 32b1 to the laver net curtain 11, and will not hinder the rotating bracket 32b from driving the buoy 31 to rotate above the net curtain, that is, the suspension mode.

[0070] In order to prevent damage to the locking device and the pneumatic motor 21, the control system 4 further comprises a spring buffer mechanism 44 arranged in the fixed base 32a to provide a buffer when the locking mechanism 41 locks the rotating support part 32.

[0071] As shown in Figure 6 The unlocking mechanism 43 further comprises an unlocking air supply pipe 43a and a manual unlocking cable 43b arranged at both ends of the locking mechanism 41, respectively. High-pressure gas is introduced into the unlocking air supply pipe 43a to push the clamping module 41a, so that the rotating support 32b and the float 31 are released. The clamping module 41a can also be manually pulled away from the clamping part 41b by pulling the manual unlocking cable 43b to complete manual unlocking. The combination of the two unlocking methods makes the device more reliable and increases the fault tolerance of unlocking.

[0072] As shown in Figure 5 The external matching equipment includes an air compressor and a gas conveying pipe. The passive magnetic control air valve further comprises an air inlet, a shell, a control element and an air outlet. The air inlet is connected with the air compressor. The air outlet is connected with the gas conveying pipe. The control element is used for controlling the flow of compressed air. The shell wraps the air inlet, the air outlet and the control element. When the pneumatic motor works, compressed air is introduced into the air inlet, the pressure energy of the compressed air is converted into mechanical energy to drive the internal rotor to move and output rotation, and then the exhaust port is discharged.

[0073] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples. The above examples and descriptions in the specification are only to illustrate the principles of the present application.
