The buoyancy of the buoyancy device is greater than the sum of the gravity of the buoyancy device and the support body of the algae reef.

The specific application process of the artificial reef of the utility model is as follows:

First, as shown in Figure 1, the whole algal reef 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 algae reef 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 Fig. 1 and Fig. 2, when the algae reef of the present invention is lowered into the water area, under the condition of calm sea surface (the waves are small), the connecting rope is stretched straight under the gravity of the algae reef support body 7. state, at this moment, 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, making the lower end of the lower piston body lean against the limit On the bit block 86; at this time, the inner vent is positioned between the upper and lower piston bodies, and the outer vent is positioned above the upper piston body; the gas in the outer airbag bag 3 will not be discharged, thereby ensuring that the algae of the utility model The reef is suspended in the sea and uses the middle, upper-middle or lower-middle layers of the water to proliferate.

As shown in Figure 3 and Figure 4, 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 lower end of the lower piston body of the utility model abuts against the limit bump, the distance between the outer vent hole and the upper piston body will determine how big the sea waves are , the wave-avoiding fuze device can discharge part of the gas in the outer air bag, so that the buoyancy device and the algae 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.

When the algae reef support body sinks, the floater of this scheme will drive the sling to float together; in this way, when the waves recede, the algae reef management personnel can easily lift the buoyancy device, the algae reef support body and the objects on it through the sling The algae are pulled up together, and the air bag is inflated again, so that the entire algae reef floats in the sea again, 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.

As shown in Figure 5, after the algae reef of the present utility model is lowered in the water area, each algae reef of the present utility model can be connected with the fixed stake 11 preset in the sea area or near the coast by traction rope 12 respectively; One end of the rope is connected with the central vertical sleeve located below the outer airbag bag, and the other end is connected with the fixed pile. Several buoyancy balls are evenly distributed on the traction rope. The fixed pile is a fixed pile fixed in the sea area or near the coast. The fixed stakes can correspond to each algae reef one by one, or several algae reefs can correspond to one fixed stake.

As shown in Figure 6, after the algal reef of the present invention is lowered into the water area, the algal reef of the present utility model can also be limited in a certain sea area by the anchor sinking method. The anchor-sinking method includes a connection floating body 13 floating on the sea surface, an anchor 15, an anchor rope 14 and a traction rope 12; wherein the anchor sinks to the seabed, and the anchor rope connects the anchor with the connection floating body; one end of the traction rope is connected with the connection floating body, The other end is connected to the central upright sleeve located below the outer airbag bag.

After the algal reef of the present utility model is lowered into the water area, the algal reef of the present utility model can also be limited in a certain sea area by another anchor sinking method; the anchor rope is fixed at the bottom of the algal reef support or outside On the side of the central vertical sleeve below the airbag bag, the anchor is sunk to the seabed, and the length of the anchor rope is greater than the distance between the algae reef support body and the seabed.
