One end of the connecting rope 4 is connected to the lower end of the lead-out rod, and the other end is connected to the algal reef support; and the end of the connecting rope connected to the algal reef support is fixed on the upper end of the column of the algal reef support. When the algae reef support body is suspended below the buoyancy device, the lower end of the lower piston body leans against the limit block. The buoyancy of the buoyancy device is greater than the sum of the gravity of the buoyancy device and the algal reef support body; specifically, the buoyancy of the buoyancy device is greater than that of the buoyancy device, the algae reef support body, the column, the rope storage box, the suspension rope and the suspension rope adaptive floating device. sum of gravity.

The specific application process of the depth-adjustable floating reef body of the present invention is as follows:

First, the algal reef support body is lifted by connecting ropes; at this time, the column 6 and the vertical excitation rod 54 are in a vertical state, and the weight 52 is hung below the vertical excitation rod by hanging rope 51, and the upper limit The bit block 55 abuts against the connecting block 56, and the limit hanging rod 512 passes through the gap 514, as shown in Fig. 1 , Fig. 4 and Fig. 5 ;

Second, pull up the vertical trigger rod, then place the hanging ring 513 in the gap; then, release the vertical trigger rod, and make the limit hanging rod 512 pass through the hanging ring to hang the hanging ring on the On the limit hanging rod, so that the floating ball 511 is hung on the limit hanging rod, as shown in Figure 4 and Figure 5;

Third, as shown in Figure 1, the entire reef body is lowered into the water area, and the algal reef support body 7 is suspended in the water area by the buoyancy device 1 and the connecting rope 4; and the algal reef support can be controlled by adjusting the length of the connecting rope The depth of body hanging, using the middle layer, upper middle layer or lower middle layer of the water area for proliferation. The reef body in this embodiment is suitable for putting in the sea area with a depth of 20 to 100 meters, wherein the length of the connecting rope is between 10 and 50 meters; the length of the suspension rope is greater than the depth of the sea area where the algae reef is located.

As shown in Figure 1 and Figure 3, when the reef body of the present invention is lowered into the water area, under the condition of calm sea surface (small waves), the connecting rope is in a stretched state under the gravity of the algae reef support body 7 , at this time, the gravity of the algae reef support body 7 will act on the upper and lower piston bodies 82, 85 through the connecting rope 4, thereby overcoming the reset force of the first compression spring 87, and making the lower end of the lower piston body lean against the limit position. On the block 86; at this time, the inner vent is located between the upper and lower piston bodies, and the outer vent is located above the upper piston body; the gas in the outer airbag bag 3 will not be discharged, thereby ensuring that the algae reef of the present invention is suspended In the sea area, use the middle layer, upper middle layer or lower middle layer of the water area for proliferation.

As shown in Figure 6 and Figure 7, in the case of large waves, such as 5-level waves and 6-level waves (wave height 2 to 6 meters); since the buoyancy device 1 floats on the sea surface, the buoyancy device will Fluctuates up and down with the waves; when the buoyancy device moves up with the waves, the buoyancy device will drive the algal reef support body 7 to move up together through the connecting rope 4; when the buoyancy device moves up to the highest position with the waves, And when moving down with the waves, the algae reef support body 7 will probably continue to move up under the action of inertia until the algae reef support body reaches the highest point (in a certain distance where the buoyancy device floats down with the waves, the algae reef The reef support body may continue to move upwards, so that the distance between the buoyancy device 1 and the algal reef support body 7 will be less than the length of the connecting rope 4, and the greater the waves, the greater the fluctuation amplitude of the distance between the buoyancy device and the algae reef support body. larger); thus in this process, the gravity of the algae reef support body 7 cannot act on the upper and lower piston bodies through the connecting rope 4, and at this time, the upper and lower piston bodies 82, 85 will be pushed under the action of the first compression spring 87 Moving up, when the inner and outer two exhaust holes 81,83 are all located between the upper and lower piston bodies, part of the gas in the outer airbag bag 3 will be discharged by the inner and outer two exhaust holes, so that the buoyancy of the buoyancy device is less than the sum of the gravity of the buoyancy device and the algal reef support body; at this time, the buoyancy device 1 and the algal reef support body 7 will sink to the bottom of the sea, thereby effectively avoiding the severe fluctuation of the suspended reef body due to large wave fluctuations, resulting in The algae attached to the algal reef are destroyed.

After the algae reef of the present invention abuts against the limit projection at the lower end of the lower piston body, the distance between the outer vent hole and the upper piston body at this time will determine how large the sea waves are when the algae reef encounters this scheme. Only the wave-avoiding fuze device can discharge part of the gas in the outer air bag, so that the buoyancy device and the algae reef support body sink. As shown in Figure 2, after the lower end of the lower piston body 85 abuts against the limit projection 86, the larger the distance between the outer exhaust hole 83 and the upper piston body 82, the "first compression spring 87 pushes the upper, The lower piston body moves upward until the inner and outer vent holes are located between the upper and lower piston bodies"—the longer this process takes; The spacing has a sufficiently large fluctuation range (that is, the difference between the length of the connecting rope and the distance between the buoyancy device and the algal reef support body is large enough); The larger the distance between the exhaust hole and the upper piston body, the larger the wave fluctuation amplitude will be to enable the wave avoidance fuze device to discharge part of the gas in the outer air bag.

When encountering small sea waves, although the distance between the buoyancy device and the algae reef support body may fluctuate at this time (that is, the distance between the buoyancy device and the algae reef support body will be less than the length of the connecting rope), the first compression spring Push the upper and lower piston bodies to move upward, but when the upper piston body has not passed the outer vent hole (that is, the outer vent hole has not yet been located between the upper and lower piston bodies), the algae support has already Sinking, the gravity of the algae reef support body will act on the upper and lower piston bodies through the connecting rope again, overcome the reset force of the first compression spring, and make the upper and lower piston bodies move downward, that is to say, when encountering a small During sea waves, it is not enough to make the wave-avoidance fuze device discharge part of the gas in the outer airbag bag; thus, after the lower end of the lower piston body abuts against the limit bump, this program can control the outer exhaust hole and the upper piston body. The distance between them determines how big the sea waves are when the algae reefs of this program run into. The wave avoidance fuze device can discharge part of the gas in the outer air bag; the buoyancy device and the algae reef support body sink. Generally speaking, when encountering large waves of grade 5 and giant waves of grade 6 (wave height 2 to 6 meters), the algae reef support body will fluctuate violently up and down, causing the algae attached to the algae reef support body to be destroyed; When there are 5-level big waves and 6-level huge waves (wave height 2-6 meters), the wave avoidance fuze device of this program can discharge part of the gas in the outer air bag; make the buoyancy device and the algae support body sink.

As shown in Fig. 1, Fig. 4 and Fig. 5, after the algal reef support body 7 sinks to the seabed, the counterweight 51 of the self-adaptive floating device 5 of the hanging rope will also be placed on the seabed, and the vertical excitation rod is at this moment Under the action of the second compression spring, it will move upward until the lower limit block abuts against the connection block; at this time, the limit link bar is located above the gap, and the link 513 is unhooked, that is, the link breaks away from the limit link bar, thereby releasing the floating ball 511. At this time, the floating ball will drive the sling to float together; in this way, when the waves recede, the maintenance personnel can easily pull up the buoyancy device, the algae reef support body and the seaweed on it through the sling, and put them in the airbag again. Inflated to re-float the entire algal reef in the sea, thereby restoring the algae field.

In addition, when the algal reef support sinks to the seabed, the inner air bag 3a can ensure that the buoyancy device always floats above the algal reef support, avoiding damage to the algae attached to the algal reef support.
