Embodiment
As shown in Fig. 2-1 to Fig. 2-4, the net cage mooring anchor leg with power pooling feature of the present utility model, comprise the sea bed anchor chain 2 for connecting anchor 1, under water anchor chain 3, float 4, buoyancy aid 5, for connecting mooring cable 6 and the sinker 7 of net cage 8.
Above-mentioned sea bed anchor chain 2 is placed on sea bed, buoyancy aid 5 and mooring cable 6 floating across the sea, the lower end of anchor chain 3 is connected with sea bed anchor chain 2 under water, upper end is connected with buoyancy aid 5, and mooring cable 6 is connected with the upper end of anchor chain 3 under water.Anchor chain 3 is connected with two floats 4 under water, these two floats 4 under water on anchor chain 3 uniform intervals distribution arrange, make the chain segment of anchor chain 3 between adjacent two floats 4, between the top float 4 and buoyancy aid 5, between bottom float 4 and sea bed anchor chain 2 under water form stretched wire respectively linear, the chain segment that these three sections of formation stretched wires are linear is hang with a sinker 7 respectively.
Above-mentioned float 4 can be streamlined float, spherical float, tubular float or other form, buoyancy aid 5 can be streamlined buoyancy aid, ball float, tubular buoyancy aid or other form, and sinker 7 can be streamlined sinker, spheral sinker, tubular sinker or other form.
The lower end of above-mentioned anchor chain under water 3 with between sea bed anchor chain 2, under water the upper end of anchor chain 3 be all connected by anchor shackle 10 with between buoyancy aid 5, under water between anchor chain 3 with float 4, between mooring cable 6 with the upper end of anchor chain 3 under water.
The operation principle of net cage mooring anchor leg of the present utility model is as follows:
As shown in Figure 3 and Figure 4, environment make a concerted effort F effect under, net cage 8 is subjected to displacement, and its position moves to P ' by P, makes to produce active force between net cage 8 and buoyancy aid 5, causes net cage 8 to drive buoyancy aid 5 to move with it.For buoyancy aid 5, also and active force can be produced between anchor chain 3 under water when it is subjected to displacement, and define the linear chain segment of three sections of stretched wires by connected two floats 4 due to anchor chain 3 under water, anchor chain 3 pairs of buoyancy aids 5 are under water made to create cushioning effect power, this cushioning effect power can the active force of partial offset net cage 8 pairs of buoyancy aids 5, thus hinder buoyancy aid 5 to move with net cage 8, the net cage 8 making to apply the utility model anchor leg be subject to identical environment make a concerted effort F effect time, the position A that its displacement B occurred occurs much smaller than the net cage 8 applying prior art anchor leg, sea bed anchor chain 2 in prior art can be effectively avoided to leave the problem of sea bed.Therefore, net cage mooring anchor leg of the present utility model forms the linear chain segment of multistage stretched wire by anchor chain 3 under water connects buoyancy aid 5, power cushioning effect is played to buoyancy aid 5, thus effectively limit the displacement of net cage 8, save the area taken needed for cage culture marine site greatly, and improve the stability of net cage system, and the stressed of net cage 8 can also be reduced, improve the safety of net cage float tube framework.And, because anchor leg of the present utility model is provided with buoyancy aid 5, the restoring force that anchor leg is needed at stormy waves stream external force of environment effect lower stress is provided by buoyancy aid 5, eliminates the burden being provided restoring force by net cage float tube framework, and its superiority is fixed in float tube framework considerably beyond early stage directly system.
The cushioning effect power that the above-mentioned anchor chain under water 3 pairs of buoyancy aids 5 produce is that the linear chain segment of formation stretched wires at different levels from top to bottom transmits formation step by step, the stretched wire linear chain segment quantity that formed of anchor chain 3 is more under water, then the buffering effect that can play is better, cost is also higher simultaneously.Therefore, above-mentioned anchor chain under water 3 also only can connect the float 4 of a float 4 or connection three or more, the combined factors such as the cost of the size that the quantity arranging float 4 should be made a concerted effort according to the depth of water of aquaculture sea area and the hydrology, environment and anchor leg are considered and carry out calculating the set-up mode of float 4.
The utility model, by being hang sinker 7 being formed in the linear chain segment of stretched wire, can promote the buffering effect of the linear chain segment of stretched wire.For being the weight of hanging sinker 7, sinker 7 in the linear chain segment of which stretched wire, the combined factors such as the size also should made a concerted effort according to the depth of water of aquaculture sea area and the hydrology, environment and the cost of anchor leg are considered and what carry out calculating sinker 7 is extension mode, if by the catenary effect that calculates only anchor chain self enough, then can not sinker be added.
The utility model does not limit to and above-mentioned embodiment; according to foregoing; according to ordinary technical knowledge and the customary means of this area; do not departing under the utility model above-mentioned basic fundamental thought prerequisite; the utility model can also make the equivalent modifications of other various ways, replacement or change, all drops among protection domain of the present utility model.
