Wind wave prevention fuze mechanism 3 comprises in inverted U-shaped bracing frame 31, be parallel to each other two vertical guide pin bushings 35, be separately positioned on the vertical guide rod 37 in two vertical guide pin bushings, be separately positioned on the horizontal axle sleeve 310 of two vertical guide rod upper ends, the rotating axostylus axostyle 33 be arranged in horizontal axle sleeve, the connecting rope 4 being fixed on the reel 32 on axostylus axostyle and being wound on reel.Bracing frame comprises the two riser 31b be parallel to each other and the transverse slat 31a connecting two riser upper ends.Two risers are between two vertical guide pin bushings, and two vertical guide pin bushings are near two riser lower ends.Two vertical guide pin bushings are connected with riser respectively by head rod 34.The outside of two vertical guide pin bushings is respectively equipped with spacing vertical rod 311, and two spacing vertical rods are connected with vertical guide pin bushing respectively by the second connecting rod 36.Two horizontal axle sleeves and vertical guide rod perpendicular, and two horizontal axle sleeves are coaxially arranged.Two riser lateral surfaces are respectively equipped with the bar shaped guide through hole 312 paralleled with vertical guide rod.Bar shaped guide through hole and horizontal axle sleeve are oppositely arranged.Reel is between two risers.The two ends of axostylus axostyle are each passed through corresponding bar shaped guide through hole and horizontal axle sleeve.On axostylus axostyle side, be positioned at outside two horizontal axle sleeves and be respectively equipped with limiting through hole; Specifically, axostylus axostyle two ends, to be positioned at outside two horizontal axle sleeves and to be coaxially respectively provided with positive stop end bar 331, and positive stop end shank diameter is greater than shaft diameter; Two positive stop end bar sides are respectively equipped with limiting through hole.Two spacing vertical rods are each passed through corresponding limiting through hole.On two riser lateral surfaces, be positioned at below bar shaped guide through hole and be respectively equipped with for limiting the descending lower limit projection 39 of horizontal axle sleeve.On two riser lateral surfaces, be positioned to be respectively equipped with above bar shaped guide through hole and overlap up upper limit projection 313 for limiting lateral shaft.On two vertical guide rods, be arranged with respectively between vertical guide pin bushing and horizontal axle sleeve and horizontal axle sleeve can be made up to move and the first Compress Spring 38 be resisted against on upper limit projection; And when horizontal axle sleeve is resisted against upper limit projection, the upper end of spacing vertical rod is positioned at the below of axostylus axostyle; When horizontal axle sleeve is resisted against lower limit projection, the upper end of spacing vertical rod is positioned at the top of axostylus axostyle.
The upper end that peg hangs is connected with buoyant device, and lower end is connected with in the middle part of transverse slat.Algal reef supporter is suspended on below wind wave prevention fuze mechanism by connecting rope.One end of connecting rope is fixed on reel; The other end is connected with algal reef supporter, and the end winding support of the connecting rope be connected with algal reef supporter is in column upper end.The buoyancy of buoyant device is greater than the gravity sum of buoyant device, the first connecting rope, wind wave prevention fuze mechanism and algal reef supporter.
The embody rule process of floating type wind wave prevention algal reef of the present invention is as follows:
As shown in Figure 1, whole algal reef is transferred in waters, by buoyant device 1, wind wave prevention fuze mechanism 3 and algal reef supporter 6 are suspended in waters, and the degree of depth that can hang by regulating the length of connecting rope 4 on reel control algal reef supporter, utilize middle level, waters, at the middle and upper levels or middle lower floor breed.It is in the marine site of 25 to 80 meters that algal reef in the present embodiment is applicable to throw in the degree of depth, and wherein, the length of connecting rope is generally between 30 to 85 meters.
As shown in Figure 1 and Figure 2, when algal reef is transferred to after in waters, two spacing vertical rods 311 are each passed through corresponding limiting through hole, and connecting rope 4 is in exceptionally straight state under the Action of Gravity Field of algal reef supporter 6, the gravity of algal reef supporter will be applied on reel 32 and axostylus axostyle 33 by connecting rope, thus overcome the reset force of the first Compress Spring 38, vertical guide rod is moved down till horizontal axle sleeve 310 is resisted against lower limit projection 39.Now, the limited vertical rod of axostylus axostyle of reel is blocked, and cannot rotate, thus be suspended in waters by algal reef supporter, utilize middle level, waters, at the middle and upper levels or middle lower floor breed.
As shown in Figure 3, Figure 4, when running into wave and being larger, such as, there are 5 grades of billows, 6 grades of billow (wave height 2 ~ 6 meters); Because buoyant device 1 is across the sea floating, buoyant device together will fluctuate up and down with the fluctuation of wave; When buoyant device up moves with the fluctuation of wave, buoyant device will drive algal reef supporter together up to move by connecting rope; When buoyant device up moves to extreme higher position with wave, and toward when moving down with wave, algal reef supporter 6 probably also moves in continuation under effect of inertia, until algal reef supporter peaks (in the segment distance that buoyant device down floats with wave, algal reef supporter moves on all may continuing, spacing between such buoyant device and algal reef supporter will be less than the length of connecting rope, and the fluctuating range of spacing between the larger buoyant device of wave and main body rod member upper end can be larger); Thus the gravity of algal reef supporter 6 cannot be applied on reel and axostylus axostyle by connecting rope in this process, now under the effect of the first Compress Spring 38, vertical for promotion guide rod 37 and horizontal axle sleeve 310 are up moved, until horizontal axle sleeve is resisted against upper limit projection 313.When horizontal axle sleeve is resisted against upper limit projection, the upper end of spacing vertical rod 311 is positioned at the below of axostylus axostyle, and namely spacing vertical rod and axostylus axostyle are thrown off; Thus now the gravity of algal reef supporter is applied to after on reel and axostylus axostyle by connecting rope, and the connecting rope on reel around spindle rotation, thus will discharge by reel gradually, makes algal reef supporter sink to seabed; And then effectively avoid, because wave fluctuation is comparatively large, each algal reef supporter is fluctuated acutely, and causing the marine alga that each algal reef supporter adheres to be destroyed.
Wind wave prevention fuze mechanism of the present invention is after horizontal axle sleeve is resisted against upper limit projection, the large young pathbreaker of spacing in spacing vertical rod now and between axostylus axostyle determines that this programme algal reef is when running into great wave, wind wave prevention fuze mechanism can discharge the connecting rope on reel, and algal reef supporter is sunk.As shown in Figure 2, after horizontal axle sleeve is resisted against upper limit projection, spacing in spacing vertical rod now and between axostylus axostyle is larger, then " under the effect of the first Compress Spring, vertical for promotion guide rod and horizontal axle sleeve are up moved, spacing vertical rod and axostylus axostyle are thrown off "---the time needed for this process is longer; This has enough large fluctuating range (namely the difference of the length of connecting rope and the spacing between buoyant device and algal reef supporter is enough large) with regard to needing the spacing between buoyant device and algal reef supporter; Thus after horizontal axle sleeve is resisted against upper limit projection, the spacing in spacing vertical rod now and between axostylus axostyle is larger, then need larger wave fluctuating range that wind wave prevention fuze mechanism can be made to discharge connecting rope on reel, algal reef supporter is sunk.
When running into little wave, although the spacing between buoyant device and algal reef supporter may produce fluctuate (spacing namely between buoyant device and algal reef supporter will be less than the length of connecting rope), the first Compress Spring is made to promote vertical guide rod and horizontal axle sleeve up moves, but its algal reef supporter before spacing vertical rod and axostylus axostyle are thrown off sinks, the gravity of algal reef supporter will be applied on reel and axostylus axostyle by connecting rope again, overcome the reset force of the first Compress Spring, axostylus axostyle is moved down, that is when running into little wave, it is not enough to make the connecting rope on wind wave prevention fuze mechanism release reel.In general, when running into 5 grades of billows, 6 grades billow (wave height 2 ~ 6 meters), algal reef supporter, by violent the fluctuating of generation, causes the marine alga that algal reef supporter adheres to be destroyed; Thus, when running into 5 grades of billows, 6 grades billow (wave height 2 ~ 6 meters), the wind wave prevention fuze mechanism of this programme, by the connecting rope on release reel, makes algal reef supporter sink; Effectively avoid, because wave fluctuation is comparatively large, each algal reef supporter is fluctuated acutely, and causing the marine alga that each algal reef supporter adheres to be destroyed.After wave is decorporated, attendant can by connecting rope by algal reef supporter and on marine alga together pull-up, again connecting rope is wound on reel, and two spacing vertical rods are each passed through corresponding limiting through hole, blocked by the axostylus axostyle of spacing vertical rod by reel, thus be again suspended in waters by algal reef supporter, thus recover algae field.
