Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent.
As shown in fig. 1-3, the present invention provides a floating body device for preventing capsizing, wherein the floating body device 3 of the outer ring of the floating body 1 is connected with the floating body device 3 through a floating body connector 4, a protruding clamping block 402 on a connecting rod of the floating body device is embedded into the floating body connector 4 with a clamping groove, and the floating body device is kept relatively static and stable in stormy waves under the action of an elastic clamping claw 401, and an inner floating body 2 is connected with the floating body device 3 through a floating body connecting rod 5. Meanwhile, the arrangement of the watertight cover 6 and the watertight sealing strips 7 can effectively ensure that the floating body device has good watertight performance when the air bag is not inflated. In the specific arrangement, the arrangement can be carried out in a topological mode of linear array arrangement and annular array arrangement, so that when the outermost ring floating bodies 1 are broken, all the outermost ring floating bodies 1 are discharged to obtain new stable and balanced buoyancy. When the pressure sensor senses dangerous behavior, the pressure sensor triggers the igniter to detonate the igniter, and chemical reaction is generated: 2NaN 3 =2Na+3N 2 And ≡. A large amount of nitrogen gas is rapidly flushed into the air bags of the respective air bag chambers through the air outlet holes 20 arranged on the inner tube 10.
As shown in fig. 4-5, the floating body device is in a closed watertight state in the initial state, after the air bags in the four air bag chambers are inflated, the watertight covers 6 are respectively separated from two sides, the expandable pontoons 9 are also expanded along the central symmetrical positions, the springs in the expandable sleeve 11 are stretched and actively pushed out of the outermost floating body 1 connected in the floating body connector 4 after being compressed by the limiting sleeve 8, and the floating body connecting rod 5 continuously keeps the connection of the floating body device 3 and the internal floating body 2.
As shown in fig. 6-7, the space formed by the expandable pontoon 9 and the inner tube 10 in the air bag group is divided into four air bag chambers which are respectively symmetrical up and down and left and right by the arc-shaped limiter 12 and the annular elastic limiter 13, and the opening and closing of the air bag chambers are mainly generated by the mutual linkage action generated by the inner tube 10, the expandable pontoon 9, the watertight cover 6, the rope rod structure 14 and the rope reel 15 after the air bag is inflated. When the outermost ring floating body 1 is impacted, after the gas is conveyed through the gas outlet hole 20, the air bag rapidly expands to push the rope rod structure 14 at the center of the inner cylinder 10, the tensioned elastic rope 1402 can generate downward tension to unwind the constraint of the rope reel 15 and release the residual elastic cable 1503 stored in the rope reel 15, and meanwhile, the spring in the air bag can be compressed by the limit sleeve 8 due to the thrust generated by the air bag extruding the stretchable sleeve 11, so that the displacement allowance is generated and the outermost ring floating body 1 is pushed out. The surplus of the air bag expansion of the four air bag chambers can push out the watertight covers 6 from two sides, so that new buoyancy is generated, and the shape stability of the floating body device 3 is ensured. Meanwhile, the shock-absorbing springs 16, the upper gaskets 17 and the lower gaskets 18 which are circumferentially arranged according to a certain rule can reduce damage of impact to the floating body device 3.
As shown in fig. 8-10, a sliding groove 1401 is arranged in the inner cylinder 10 from the center of the inner cylinder 10, so that after the air bag is inflated, the sliding rod 1407 is pushed, and the long rod 1403 in the fixer 1406 connected with the sliding rod 1405 is driven to move, so that the sliding rod metal buckle 1405 is free from the constraint of the rubber hook 601 with a watertight cover. As the balloon is inflated, the long rod 1403 will disengage from the chute 1401 after moving to the chute disengagement position 1404 where the cross-sectional area is abrupt; while the initially tensioned elastic cord 1402 will give its increased tension to the cord reel 15 a downward pull after displacement and unwind its tie to the internal balance cord; the expansion of the air bags symmetrically up and down will drive the elastic cables 1503. The expansion of the upper and lower air bag chambers will increase in volume, and with the increase of the air bags symmetrically arranged left and right, the watertight cover rubber gasket 602 will also disengage from the expandable pontoon 9, i.e. the watertight cover 6 will drop off.
As shown in fig. 11-13, the cord reel 15 is comprised of an outer housing 1501 with rubber washers 1504, a drive pulley 1505, a knob 1507, housing rubber hooks 1508, symmetrically arranged cord holders 1510 and limit bars 1511, and a cover 1502 with driven pulleys 1506 and cover metal buttons 1509 corresponding to the cord holders 1510. The head of its inner elastic cable 1503 is fixed to its inner stop bar 1511 and both ends of the elastic cable 1503 are retracted in the rope grooves of the rope cable connector 1510 in a clockwise and counterclockwise rotational direction, respectively. Gears of the driven wheels 1506 on two sides are respectively buckled with the gears of the driving wheel 1505, and the linkage operation is controlled through a knob 1507 arranged in the center of the driving wheel 1505 so as to achieve the effect of elastic ropes 1503; the inner elastic ropes 1503 pass through the elastic holes 1512 of the outer housing 1501 of the rope reel 15 respectively and pass through the linearly arranged hemispherical tether holes 19 in the expandable buoy 9 respectively in an "8" encircling manner; the elastic cable 1503 may be tensioned by rotating knob 1507 to achieve an initial watertight effect; when the balloon is inflated, the cover 1502 will be pulled obliquely downward and the cover 1502 will be freed from the restraining of the rubber gasket 1504 and the annularly arranged housing rubber hooks 1508 and cover metal buckles 1509 and will fall off, and the fall off of the driven wheel 1506 will release the elastic cable 1503 that is contracted to the cable connector 1510, allowing the float device 3 to achieve a volumetric expansion effect to provide more buoyancy.
14-15, the outer sleeve 1101 of the telescopic sleeve 11 is fixedly installed on one side of the expandable pontoon 9, the lower end of the outer sleeve is annularly provided with a sliding rail for providing a moving track for the push rod 1102 and eight saw-tooth protrusions at the disengaging position of the sliding rail, the upper part of the push rod 1102 is annularly provided with eight protrusions corresponding to the sliding grooves of the outer sleeve 1101 respectively, and the head of the push rod 1102 is provided with eight saw-tooth protrusions for providing a foundation for converting linear motion into rotary motion; the slender rod of the cam 1103 is arranged at the hollow position of the push rod 1102, and four sawtooth bulges are mutually corresponding to eight sawtooth bulges of the push rod 1102 at intervals and all face the direction of the push rod 1102; the outer push rod 1104 is also arranged at the hollow position of the cam 1103 and is sleeved with a telescopic spring 1105; a stop sleeve 8 is disposed on top of the extendable sleeve 11, the stop sleeve 8 being connected to the outer sleeve 1101 and to the float connector 4. When the air bag rapidly expands, the pressure of the air bag pushes the push rod 1102, the bulge of the push rod 1102 slides into a preset track in the sliding groove of the outer sleeve 1101 to drive the push rod 1104 to move upwards, the telescopic spring 1105 contracts under the constraint of the limiting sleeve 8, the generated displacement allowance enables the cam 1103 to reach the sawtooth protrusion at the edge of the sliding rail of the outer sleeve 1101, the cam 1103 is scratched into the gear protrusion of the push rod 1102 along with the increase of the displacement allowance, the rotation amplitude is increased, and the effect that the extension push rod 1104 pushes out the outermost ring floating body 1 fixed at the floating body connector 4 is achieved.
In this embodiment, after the pressure sensor triggers ignition and detonates gas, the floating body device will combine the rope rod structure, the rope reel and the extendable sleeve through the expansion of the air bag, the extendable pontoon pushes out the damaged outer ring floating body to provide new stable and balanced buoyancy, the internal floating body and the construction operation thereof are ensured to be orderly, safely and stably carried out, and the whole structure can not roll, surge or even topple under the action of sea waves due to a great deal of local buoyancy loss.
