As shown in Figure 1, one end of connecting rope 4 is connected with buoyant device, and the other end is connected with the main body Rod end near locking nut, and the connecting rope end winding support be connected with buoyant device is in the lower end of leading-off rods; One end (i.e. upper end) of connecting rope is connected with the lower end of leading-off rods, and the other end (i.e. lower end) is connected with the main body Rod end near locking nut.When each algal reef supporter is suspended on below buoyant device, the lower end abutment of lower piston body is on limited block.The buoyancy of buoyant device is greater than the gravity sum of buoyant device, connecting rope, main body rod member, each algal reef supporter, Chu Shengxiang, lifting rope and lifting rope self adaptation levitating device.
The embody rule process of artificial algal reef of the present invention is as follows:
The first, utilize the plant equipment such as lifting machine, and by connecting rope by main body rod member and on each algal reef supporter sling; Now, main body rod member 6, connects vertical cover 72, vertically excite bar 54 to be in vertical state, weight 52 is vertically excited below bar by being hung on of dangling of lanyard 51, and upper limit position block 55 is resisted against on contiguous block 56, spacing peg 512 through breach 514 of stepping down, as shown in Figure 1, Figure 4, Figure 5;
The second, will vertically excite bar toward pull-up, then link 513 is placed in and steps down in breach; Again then, release vertically excites bar, and link is hung on spacing peg through link by spacing peg 512, thus ball float 511 is hung on spacing peg place, as shown in Figure 4, Figure 5;
3rd, as shown in Figure 1, whole algal reef is transferred in waters, by buoyant device 1 and connecting rope 4, main body rod member and each algal reef supporter 7 are suspended in waters; And the degree of depth that can hang by regulating the length of connecting rope 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 20 to 100 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 10 to 50 meters; The length of lifting rope is greater than the degree of depth in marine site.
As shown in Fig. 1, Fig. 6, when algal reef of the present invention is transferred to after in waters, when sea (wave is less) of calmness, under the Action of Gravity Field of algal reef supporter 7, connecting rope is in exceptionally straight state, now, the gravity of algal reef supporter 7 will be applied on upper and lower piston body 82,85 by connecting rope 4, thus overcome the reset force of the first Compress Spring 87, make the lower end abutment of lower piston body on limited block 86; Now, inner vent is between upper and lower two-piston body, and outer vent is positioned at above upper piston body; Gas in gasbag 3 can not be got rid of, thus ensures that algal reef of the present invention is suspended in marine site, utilize middle level, waters, at the middle and upper levels or middle lower floor breed.
As shown in Figure 7, Figure 8, 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 main body rod member and each algal reef supporter 7 together up to move by connecting rope 4; When buoyant device up moves to extreme higher position with wave, and toward when moving down with wave, main body rod member and each algal reef supporter probably also move 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 1 and main body rod member upper end will be less than the length of connecting rope 4, 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 each algal reef supporter 7 cannot be applied on upper and lower piston body by connecting rope 4 in this process, upper and lower piston body 82,85 will be promoted under the effect of now the first Compress Spring 87 up to move, when inside and outside two air vents 81,83 are all between upper and lower two-piston body, portion gas in gasbag 3 will be discharged by inside and outside two air vents, make the buoyancy of buoyant device be less than the gravity sum of buoyant device and each algal reef supporter; Now, buoyant device 1 and each algal reef supporter 7 will sink to seabed, thus 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.
Algal reef of the present invention is after the lower end abutment of lower piston body is on spacing block set, the large young pathbreaker of spacing between outer vent now and upper piston body determines that this programme algal reef is when running into great wave, keep away unrestrained fuze mechanism the portion gas in gasbag to be discharged, buoyant device and algal reef supporter are sunk.As shown in Figure 6, after the lower end abutment of lower piston body 85 is on spacing block set 86, spacing between outer vent 83 and upper piston body 82 is larger, then " the first Compress Spring 87 promotes upper and lower piston body and up moves, until inside and outside two air vents are all between upper and lower two-piston body "---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 main body rod member upper end is enough large) with regard to needing the spacing between buoyant device and main body rod member upper end; Thus after the lower end abutment of lower piston body is on spacing block set, the spacing between outer vent and upper piston body is larger, then need larger wave fluctuating range can make to keep away unrestrained fuze mechanism and discharged by the portion gas in gasbag.
When running into little wave, although the spacing between buoyant device and main body rod member upper end may now fluctuate (spacing namely between buoyant device and main body rod member upper end will be less than the length of connecting rope), first Compress Spring is promoted, lower piston body up moves, but it is not when upper piston body also up crosses outer vent, and (outer vent is not also positioned at, between two lower piston bodies), each algal reef supporter sinks, the gravity of algal reef supporter will be applied to by connecting rope again, on lower piston body, overcome the reset force of the first Compress Spring, make, lower piston body moves down, that is when running into little wave, it is not enough to make to keep away unrestrained fuze mechanism and is discharged by the portion gas in gasbag, thus after the lower end abutment of lower piston body is on spacing block set, this programme can decide this programme algal reef when running into great wave by the spacing size controlled between outer vent and upper piston body, and keeping away unrestrained fuze mechanism can discharge the portion gas in gasbag, buoyant device and algal reef supporter are sunk.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 unrestrained fuze mechanism of keeping away of this programme can by the portion gas discharge in gasbag; Buoyant device and algal reef supporter are sunk.
As shown in Figure 1, Figure 4, Figure 5, after algal reef supporter 7 sinks to seabed, the balancing weight 51 of lifting rope self adaptation levitating device 5 also will be placed at seabed, now vertically excite bar will up move under the second Compress Spring effect until lower position block is resisted against on contiguous block; Now spacing peg is positioned at above breach of stepping down, and link 513 breaks off relations, and namely link departs from spacing peg, thus release ball float 511, now drive lifting rope together floats by ball float; Like this after wave is decorporated, attendant can easily by lifting rope by buoyant device, algal reef supporter and on marine alga together pull-up, and again to inflate in gasbag, whole algal reef swum in marine site again, thus recover algae field.
