Reinforcing bar sinker (9) can not only make the etting following sea fall after rise fast, can also alleviate etting undue drift under the impact of trend.The weight principle of a bottom placing of reinforcement sinker (9) is only by an etting section counterweight; And the counterweight (when bottom placing of reinforcement sinker (a 9) low tide falls into the seabed) of a top row's reinforcing bar sinker (9) should bear the counterweight of all etting sections above it; Total counterweight of two placing of reinforcement sinkers (9) is to be advisable for 8 kilograms with reference to every gross weight along long rice with the present embodiment according to experiment.
The buoyancy size that the every linear meter of rectangular buoy net scraper (7) produces can be calculated through following method with the required weight of the every linear meter of seabed sinker (10): (amounting to decimetre to keep the two-decimal point size)
Adopt common 0.8 decimeter thick, 1.0 decimeters wide kahikateas are cooked rectangular flitch
Then the area of section of rectangular flitch is: S=0.6 decimetre * 1.0 decimeter=0.6 decimeter
2
If the total length of rectangular flitch is: the L=10 decimetre
Then rectangular flitch cumulative volume is: V=S * L=0.6 decimetre
2Q * 10 decimeter=6 decimeters
3
The proportion of seawater is at least d=1
The buoyancy that the rectangular flitch of then every linear meter can produce in seawater at least is: F floats=V * d=6 kilogram
The proportion of kahikatea flitch is d=0.41
The own wt of the rectangular flitch of then every linear meter kahikatea is: G=V * d=6 * 0.41=2.46 kilogram
The consideration kahikatea is soaked proportion for a long time and can increase to some extent in water, select 1.2 to be enhancement coefficient
The weight of the rectangular flitch of then every linear meter kahikatea is: G=6 * 0.41 * 1.2=2.95 kilogram
The net buoyancy that the rectangular flitch of then every linear meter kahikatea is produced is: floating=6 kilograms-2.95 kilograms=3.05 kilograms of F.Be used to overcome net is scraped and etting (2) between frictional force.
The weight of the every linear meter of seabed sinker is relevant with the gross buoyancy that rectangular buoy net scraper produces, and the gross buoyancy that produces with the every linear meter of present embodiment (see figure 1) 4 row's buoy net scrapers is: F=4 * 3.05 kilogram=12.2 kilograms
The weight of seabed sinker (10) should be decided according to the ability to bear of above-mentioned result of calculation and etting float (1); The gross buoyancy that produced greater than kahikatea flitch float in the marine total force that can produce of seabed sinker (10) in principle; At least be 1.5 times of its F gross buoyancy, i.e. 12.2 kilograms * 1.5=18.3 kilogram.So that when the seawater full sea, can produce enough pulling force, overcome the gross buoyancy that rectangular flitch makes progress, it is pulled to the bottom (seeing the Fig. 2-1 among Fig. 6) of each etting section.
Total counterweight of two placing of reinforcement sinkers (9) is to be advisable for 8 kilograms with reference to the every gross weight along long rice of two placing of reinforcement sinkers (9) with the present embodiment according to experiment.
By the foregoing description requirement adjustment float (1), full towards the time seabed sinker (10) break away from the seabed fully, float (1) has 1/3 volume to expose the sea.
