Application method：
In use, setting etting just to can be used on lift aquaculture net cage, in use, because vertical rigidity is hung
The presence of beam 3 and horizontal stiffness crossbeam 4 so that net cage integral rigidity preferably, deforms very little under flow action, can effectively kept
The volume of net cage.When in use, the power (buoyancy of scaffold system) on net cage top is evenly transferred on vertical rigid hanging beam, size
Equal, direction is vertical upwards, F1 as shown in Figure 6.The power of net cage bottom is all evenly transferred on horizontal stiffness crossbeam 4, greatly
It is small equal, axial direction of the direction along horizontal gird.As shown in figure 8,5 power come together in a point P, i.e., in crossbeam corner connection.Its
In the direction of each power be along the axially extending direction of rigid member or flexible member, it is equally loaded, can be effective gram
Take net cage deformation.Normally in use, opening sand discharge valve, water discharging valve and air intake valve, keg float sinking affected by gravity,
Simultaneously seawater by sand discharge valve and water discharging valve automatically into keg float.The injection of water will along with the Action of Gravity Field of steel underframe
It is final to overcome itself upward buoyancy of elevating control bucket.When needing to sink under water in net cage, bottom flushing of sediment valve is closed, floating
The artificial grains of sand toward the filling enough volumes of sand inlet on the operation panel of frame system, play it and overcome the buoyancy of float tube to provide sinking
The effect of power, and then change the overall stressing conditions of net cage, break original poised state, net cage is started sinking.Make net
Case need to only open water discharging valve when floating, and squeeze into the gases at high pressure for overcoming water-bed pressure toward air inlet, discharge water, keg float gravity
Reduce, buoyancy increase, make it that the Whole power of net cage is upward until changing original poised state, net cage just can realize floating.
During rising and sinking, due to the anti-presence for swinging cloth so that its rise and sink it is relatively more steady, can avoid the shoal of fish by
To agitation.In fishing, pull-off is used for the bolt for limiting hanging beam rising, due to the effect of hanging beam end flange and hanging beam pintle hook lock,
Now pull-off bolt, net cage bottom will not still sink.Control to open the sand discharge valve of keg float bottom by electromagnetic principle, due to
The effect of self gravitation, sandstone leak into seabed gradually, so as to reduce the weight inside keg float.The draining valve closed in the middle part of keg float
Door, continues to squeeze into pressure-air, discharges the water of keg float, air has occupied most of volume of whole keg float toward air inlet, from
And the gradually increase of keg float buoyancy, float up that promotion is anti-to swing cloth, drive steel framework to rise, until net bottom rise to it is appropriate
Untill position.
Obviously, the above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not pair
The restriction of embodiments of the present invention.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.It is all this
Any modifications, equivalent substitutions and improvements made within the spirit and principle of invention etc., should be included in the claims in the present invention
Protection domain within.
