The specific embodiment
Below will be with reference to the accompanying drawings the utility model be described in detail principle of work at the buoyancy hoisting device.
Load hydrogen bearing alloy MlNi under water in the bin 10 of hoisting device
5(Ml is a lanthanum rich mischmetal) 0.1 kilogram, gas chamber volume is 8 liters.At neritic province domain (depth of water is less than 500 meters), when floating drum sank in the ocean, shutoff valve 207 was closed.Hydrogen storage is in hydrogen bearing alloy 10 under the room temperature, and the air chamber of floating drum is compressed, and displacement is minimum.In the floating drum sinking process, seawater enters floating drum by the intake-outlet 13 at floating drum top, after arriving desired depth, temperature of heating plate raise when clock relay 205 was connected the circuit of nickel-hydrogen accumulators 11 and heating plate 7, then add thermal hydrogen storage alloy, hydrogen content and temperature according to hydrogen bearing alloy, relation between the hydrogen pressure, the hydrogen that is stored in the hydrogen bearing alloy gold begins to discharge, hydrogen sees through filter 6 and enters air chamber 15 by outgas pipe 209 by pressure-adjusting type check valve 206, under the pressure of release hydrogen promotes, piston 4 relies on the location of piston rod to move to the floating drum top along floating drum 12 axis, and seawater is discharged floating drum by intake-outlet 13, obtains buoyancy.When piston 4 arrives the floating drum top, cut off circuit by clock relay 205.This moment, hydrogen bearing alloy 10 began to cool down, and the hydrogen in the bin is absorbed by hydrogen storage material, makes the bin internal pressure be lower than the air chamber internal pressure.But because the obstruct of pressure regulation check valve 206, the hydrogen in the floating drum air chamber 15 can not be absorbed by hydrogen bearing alloy by outgas pipe 209, from keeping the displacement of floating drum.
The seabed article hang the process of liter as shown in Figure 3, the grapple 306 at hoisting device 303 tops is connected on the winch 304 that is fixed on platform 302 with platform 302 by rope chain 301 under water, by winch 304 lanyard chains 301, can be simply easily 4 kilograms of seabed goods 305 be hung and be raised to the sea by the grapple 307 of hoisting device 303 bottoms under water.After unloading goods, open shutoff valve 207, at room temperature, the hydrogen in the floating drum air chamber 15 is absorbed by hydrogen bearing alloy by cylinder 208, and piston 4 beginnings are moved to the floating drum bottom.After all hydrogen are absorbed, close shutoff valve 207, floating drum is returned treat worker's state.
It is lithium ion battery, Ni-MH battery that storage battery can be selected for use, can recharge, thus guarantee that hoisting device is reusable under water.
When carrying out deep-sea (depth of water is greater than 500 meters) operation, use high-pressure hydrogen storing alloy such as Mm
1-yCa
