Abstract
Make the buoyant structure that equipment sinking latter end bottoms out at a slow speed by installing standby frame, buoyancy tank, weight, the compositions such as depthkeeping rope, depthkeeping hammer, during sinking, depthkeeping is hammered into shape under, and frame and equipment are upper, when depthkeeping hammer bottoms out, frame discharges bottom weight, increases buoyancy, reduces frame and the subsidence velocity of equipment, after frame and equipment bottom out at a slow speed, buoyancy tank valve is opened, and pours into water, buoyancy is reduced, frame and equipment is made to stablize seat bottom.
Description
Technical field
Equipment platform in water refers in particular to a kind of buoyant structure that equipment sinking latter end is made to bottom out at a slow speed.
Background technology
It sinks to the bottom equipment such as bottom mine, sink to the bottom after detection equipment launches water quickly to sink, otherwise can be subject to ocean current or river
Stream is influenced and drift about, influences to launch precision, out of position, but it is quick under sinking and contacting bottom easily make equipment be subject to sharp impacts and
It is impaired or be absorbed in silt, cause to sink to the bottom equipment being unable to normal use.
The content of the invention
The present invention Basic Design thinking be：Equipment will be sunk to the bottom to be put into the frame of buoyant structure, have floating drum on frame, weight is arranged at lower part
With the depthkeeping hammer of depthkeeping rope suspension, negative buoyancy force is larger, enters first quick sinking after water, when depthkeeping hammer bottoms out, throws lower weight, reduce
Negative buoyancy force or even with certain positive buoyancy, slows down the decrease speed of equipment and platform, after bottoming out at a slow speed, then opens frame floating
The valve of cylinder discharges air, fills water, reduce the buoyancy of equipment, and equipment and platform is made to keep stablizing and sit bottom.
It is the container or frame that do not have to waterproof to make the buoyant structure main body that equipment sinking latter end bottoms out at a slow speed, and sinking to the bottom equipment can fill
Wherein and fixed, the bottom center of frame is to connect the depthkeeping hammer that depthkeeping rope and depthkeeping are hammered into shape to bottom out induction mechanism, and periphery is can
With the weight freed；The side surface upper part of frame connects float or floating drum, also has acceleration transducer on frame.
After ensureing to load onto and sinking to the bottom equipment, whole center of gravity is below frame center, and after weight is freed, center of gravity moves up, but still is to lean on
Under, rolling or big inclination will not occur in sinking watching.
When depthkeeping hammer bottoms out, control weight after induction mechanism perceives is bottomed out by depthkeeping hammer and is freed, weight is the sand that sack is filled with
Or finger stone, when freeing, sack is opened, and sandstone sink to spreading to the bottom rapidly, will not be as ratchel weight to sinking to the bottom frame
It is impacted with equipment.
Frame top is arming mechanism, connects float or floating drum.Discounting for hidden, float can also sink in the surface of frame
After bottom equipment bottoms out, float, which is freed, floats to the water surface.If it is considered that hidden, then using hollow float, mounted in the side top of frame,
It sinks to the bottom after equipment bottoms out, floating drum water filling loss of buoyance, remains stationary as or sink to the bottom of frame side.There is kingston valve on floating drum,
If for air in floating drum, for kingston valve at the top of floating drum, when water filling, can generate bubble floating to the water surface.It can be pumped into floating drum true
Sky, kingston valve do not generate bubble floating at bottom, water filling, increase concealment.Floating drum can also connect compressed gas cylinder and inflation
Device, it is necessary to when compressed gas cylinder can be controlled to be inflated into floating drum, its is made to increase buoyancy, with sinking to the bottom equipment and frame floats to water
Face；Floating drum can be hauled by the rope of frame bottom, and after water filling becomes negative buoyancy force, floating drum sinks to the bottom of outer frame.
There is acceleration transducer on frame, perceive after bottoming out and stablizing, send instruction, open kingston valve, floating drum water filling loses
Buoyancy or float is made to free floating.
Description of the drawings
Fig. 1 is a kind of buoyant structure basic block diagram that equipment sinking latter end is made to bottom out at a slow speed.
Wherein：1. floating drum, 2. frames, 3. acceleration transducers, 4. weight arming mechanisms, 5. weights, 6. depthkeeping ropes, 7. depthkeepings hammer,
8. kingston valve, 9. floating drum traction ropes, 10. sink to the bottom equipment, and 11. depthkeepings hammer bottoms out induction mechanism.
Specific embodiment
It is fixed in use, first sinking to the bottom equipment by 10. in 2. frames, during dispensing, hammers 7. depthkeepings into shape submerged, 6. depthkeeping ropes are drawn
It after straight, then discharge 10. and sinks to the bottom equipment and 2. frames, make its integral sinking.
Platform and 10. sinks to the bottom equipment first quick sinking, and 7. depthkeepings hammer keeps certain pulling force under, to 6. depthkeeping ropes, makes 11. depthkeepings
Hammer bottoms out the spring elongation of induction mechanism, when 7. depthkeepings hammer bottoms out, disappears to the pulling force of 6. depthkeeping ropes, spring shortens, and touches
4. weight arming mechanism frees 5. weights and sinks, at this time therefore the buoyancy increase of platform, decrease speed reduce；3. accelerate
Degree sensor senses are sunk to the bottom to platform and 10. after equipment slowly bottoms out and stablize, and send instruction immediately and float is controlled to free or beat
The kingston valve on 1. floating drums is opened, water is made to be sunk to the bottom after pouring into, reduces the buoyancy of platform, increases and sinks to the bottom the stability that equipment sits bottom, 9.
Floating drum traction rope makes 1. floating drums not fall on 10. to sink to the bottom on equipment.
It needs to sink to the bottom equipment and the weight of platform according to 10., it is much to calculate whole body negative buoyancy force for volume.According to what is calculated
Whole negative buoyancy force size and it is expected that subsidence velocity, 6. definite depthkeeping rope length degree.
