The support frame includes two vertical plates 31b parallel to each other and a horizontal plate 31a connecting the upper ends of the two vertical plates. The two vertical plates are located between the two vertical guide sleeves, and the two vertical guide sleeves are close to the lower ends of the two vertical plates. The two vertical guide sleeves are respectively connected with the vertical plate through the first connecting rod 34 . The outer sides of the two vertical guide sleeves are respectively provided with limit vertical rods 311 , and the two limit vertical rods are respectively connected with the vertical guide sleeves through second connecting rods 36 . The two horizontal shaft sleeves are perpendicular to the vertical guide rod, and the two horizontal shaft sleeves are coaxially arranged. Bar-shaped guide through holes 312 parallel to the vertical guide rods are respectively provided on the outer surfaces of the two vertical plates. The bar-shaped guide through hole is arranged opposite to the transverse shaft sleeve. The winding wheel is located between the two vertical plates. The two ends of the shaft rod pass through the corresponding bar-shaped guide through hole and the transverse shaft sleeve respectively. Limiting through holes are respectively provided on the side of the shaft and outside the two transverse bushings; specifically, the two ends of the shaft and the outsides of the two transverse bushings are respectively coaxially provided with limiting end rods 331, and the diameter of the limiting end rods It is larger than the diameter of the shaft rod; the side faces of the two limit end rods are respectively provided with limit through holes. The two position-limiting vertical rods respectively pass through the corresponding position-limiting through holes. Lower limit projections 39 for limiting the downward movement of the transverse bushing are respectively provided on the outer sides of the two vertical plates and located below the strip-shaped guide through holes. Upper limit bumps 313 for limiting the upward movement of the transverse bushing are respectively provided on the outer sides of the two vertical plates above the strip-shaped guide through holes. On the two vertical guide rods, between the vertical guide bushing and the transverse bushing, there are respectively sleeved first compression springs 38 that can move the transverse bushing upward and lean against the upper limit projection; and when the transverse bushing When abutting against the upper limit projection, the upper end of the limit vertical rod is located below the shaft; when the transverse bushing abuts against the lower limit projection, the upper end of the limit vertical rod is located above the shaft.

The upper end of the hanging rod is connected with the buoyancy device, and the lower end is connected with the middle part of the horizontal plate. The algae reef support body is suspended below the anti-wind and wave fuze device by connecting ropes. One end of the connecting rope is fixed on the reel; the other end is connected with the algae reef support body, and the end of the connection rope connected with the algae reef support body is fixed at the upper end of the column. The buoyancy of the buoyancy device is greater than the sum of the gravity of the buoyancy device, the first connecting rope, the anti-storm fuze device and the algae reef support body.

The concrete application process of seaweed breeding reef of the present utility model is as follows:

As shown in Figure 1, the whole algae reef is lowered into the water area, the anti-storm fuze device 3 and the algae reef support body 6 are suspended in the water area by the buoyancy device 1, and the length of the connecting rope 4 can be adjusted by adjusting the reel. Control the hanging depth of the algae reef support body, and use 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 being released in sea areas with a depth of 25 to 80 meters, wherein the length of the connecting rope is generally between 30 and 85 meters.

As shown in Figure 1 and Figure 2, when the algae reef is lowered into the water area, the two limit vertical rods 311 pass through the corresponding limit through holes respectively, and the connecting rope 4 is in tension under the gravity of the algae reef support body 6. In the straight state, the gravity of the algae reef support body will act on the reel 32 and the shaft rod 33 through the connecting rope, thereby overcoming the reset force of the first compression spring 38, and the vertical guide rod will move down until the horizontal shaft sleeve 310 is against the until the lower limit projection 39. At this time, the shaft rod of the reel is blocked by the limit pole and cannot rotate, so that the algae reef support body is suspended in the water area, and the middle layer, upper middle layer or lower middle layer of the water area is used for proliferation.

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 algae reef support to move up together through the connecting rope; when the buoyancy device moves up to the highest position with the waves, and When moving down with the waves, the algal reef support body 6 will probably continue to move upwards under the action of inertia, until the algal reef support body reaches the highest point (in a certain distance where the buoyancy device floats down with the waves, the algal reef support body may continue to move up, so that the distance between the buoyancy device and the algae reef support body will be less than the length of the connecting rope, and the greater the waves, the greater the fluctuation of the distance between the buoyancy device and the upper end of the main rod); thus In this process, the gravity of the algae reef support body 6 cannot act on the reel and the shaft through the connecting rope, and at this time, under the action of the first compression spring 38, the vertical guide rod 37 and the horizontal shaft sleeve 310 will be pushed to move upward. , until the transverse shaft sleeve abuts against the upper limit protrusion 313 . When the horizontal bushing abuts against the upper limit projection, the upper end of the limit vertical rod 311 is located below the shaft rod, that is, the limit vertical rod is disengaged from the shaft rod; thus the gravity of the algae reef support body acts through the connection rope at this time After reaching the reel and the shaft, the reel will rotate around the shaft, so that the connecting rope on the reel will be released gradually, so that the algae reef support body will sink to the bottom of the sea; thus effectively avoiding the large wave fluctuations, Each algae reef support body fluctuates violently up and down, causing the seaweed attached to each algae reef support body to be destroyed.

In the anti-wind and wave fuze device of the utility model, after the horizontal shaft sleeve abuts against the upper limit bump, the distance between the upper limit pole and the shaft rod will determine how big the sea waves will be when the algae reef of this program encounters When, the anti-wind and wave fuze device can release the connecting rope on the reel, so that the algae reef support body sinks. As shown in Figure 2, after the transverse bushing abuts against the upper limit projection, the larger the distance between the top of the limit vertical rod and the shaft rod at this time, the "the action of the first compression spring will push the vertical The guide rod and the transverse bushing move up to disengage the limit vertical rod from the shaft”—the longer the process takes; this requires a large enough distance between the buoyancy device and the algae support. The amplitude of the fluctuation is sufficient (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 top and the shaft rod, the greater the wave fluctuation amplitude is needed to make the anti-storm fuze device release the connecting rope on the reel, so that the algae reef support body sinks.

When encountering small waves, although the distance between the buoyancy device and the algae reef support body may fluctuate (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 pushes The vertical guide rod and the horizontal shaft sleeve move upwards, but the algal reef support body has sunk before the limit vertical rod is disengaged from the shaft rod, and the gravity of the algal reef support body will act on the reel and shaft through the connecting rope again. On the bar, overcome the restoring force of the first compression spring, make the axle bar move down, that is to say, when running into small waves, it is not enough to make the anti-storm fuze release the connection rope on the reel. 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 big waves of level 5 and huge waves of level 6 (wave height 2 to 6 meters), the anti-storm fuze device of this scheme will release the connecting rope on the reel to make the support body of the algae reef sink; Each algae reef support body fluctuates violently up and down, causing the seaweed attached to each algae reef support body to be destroyed. When the sea waves recede, the maintenance personnel can pull up the algae reef support body and the seaweed on it through the connecting rope, rewind the connecting rope on the winding wheel, and pass the two limit poles through the corresponding limit poles respectively. Through the hole, the shaft of the winding wheel is blocked by the limit pole, so that the algae reef support is suspended in the water area again, thereby restoring the algae field.
