Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
As shown in FIG., a kind of hydraulical impact formula torpedo anchor, is made of anchor head 18, anchor body 19, anchor chain and hydraulic impacter,
Anchor head is arranged at the lower section of anchor body, and anchor chain is divided into outer anchor chain 20 and interior anchor chain 22, and outer anchor chain is fastened fastens in the both sides of anchor head, interior anchor chain
On the top of anchor body, anchor body is divided into 2 two-part structure of inner casing 3 and shell, inner casing configuration upper end opening and hydraulic pressure in cylindrical shape
The water inlet pipe of pipeline 21 is connected, and the space between inner casing and shell is known as fluid course 15, the fluid course and fluid pressure line
Return duct be connected, the bottom of inner casing is provided with intercommunicating pore 9, the space in inner casing is connected with fluid course, the liquid
Dynamic impactor is arranged in inner casing；The hydraulic impacter is by upper limit plate 12, lower limit ring 23, valve 6 living, valve spring 6, block stamp 8
Formed with mainspring 8, inner housing inner space is divided into three parts by upper limit plate and lower limiting board, and upper limit plate is provided with inlet opening
14, block stamp is arranged between upper limit plate and lower limit ring, mainspring is set between block stamp and lower limit ring, at the middle part of block stamp
Equipped with hollow pipeline, hollow pipeline connection is arranged at the block stamp mesoporous 16 on the outside of block stamp, is provided with the center of upper limit plate
Valve opening living, valve living are arranged in valve opening living, and the structure above valve opening living is known as valve seat 4 living, in valve seat living and upper limit plate
Between be provided with valve spring 5；Anvil 10 is provided with below the hydraulic impacter, the object to exert a force downwards as block stamp.
1st, the hydraulical impact principle and process of torpedo anchor
Before opening water pump, block stamp 7 under the action of mainspring 8 in upper, when its centre bore lived valve 6 cover when, liquid
Stream is instantaneously hindered, and hydraulic pressure drastically increases and produces water hammer supercharging.Under high pressure liquid stream effect, together downlink is compressed for block stamp and valve living
Mainspring 8 and valve spring 5, the stage are known as the valve closing Acceleration of starting operation phase.When valve living goes downwards to suitable position, valve living is by valve of living
Seat limitation, stops downlink and is simultaneously disengaged with block stamp, and flushing liquor (water) passes sequentially through inlet opening 14, hollow in the middle part of flow path block stamp at this time
Pipeline, block stamp mesoporous 16, then entered by intercommunicating pore 9 in fluid course 15, the returning by fluid pressure line under the action of pump pressure
Flow tube is back to offshore operations platform, and hydraulic pressure declines, and flushing liquor also realizes recycling.Hereafter, valve living returns under valve spring effect
Original position is gone back to, and block stamp continues traveling downwardly under kinetic energy effect.After valve downlink certain distance living, limited be subject to valve seat living, under stopping
OK, and block stamp is continued traveling downwardly due to the inertia of high-speed motion, compress mainspring, hit anvil 10.At this time, piston and valve living are instantaneous
Disengage, open fluid course, valve return under the action of valve spring living.Since valve area pressure die-offs, in bullet after block stamp strike anvil
Under spring effect it is also rapid on return resets, closing fluid course and produce the second Secondary Shocks.Impactor is so continuous again and again
Work, anvil also Ground shock waves torpedo anchor anchor head in cycles, is accurately oriented injection soil layer for torpedo anchor and provides power.
2nd, hydraulical impact formula torpedo anchor installation steps
With the order of connection of " anchor body-hydraulic impacter-twin-core rubber water pipe-water pump " by hydraulical impact formula torpedo anchor in work
After installation is complete on journey ship, anchor chain is slowly transferred by loop wheel machine until anchor body contacts sea bed.Open water pump and send water, carried for impactor
For power, while gradually loosen anchor chain, allow torpedo anchor injection soil body under the action of hydraulic impacter, starting stage use is smaller
It is pumped, pump pressure can be increased after injection certain depth, after torpedo anchor reaches projected depth, switch off the pump, completes the peace of torpedo anchor
Dress.
3rd, hydraulical impact formula torpedo anchor recycling step
With the tightening anchor chain of slow, uniform speed, to drive the anchor body that surges to depart from state in place, hydraulical impact formula is completed
The recycling of torpedo anchor.
The utility model is described in detail above, but the content is only the preferred embodiment of the utility model,
It should not be considered as limiting the scope of the present invention.Equivalent change made according to the scope of application of this utility model with
Improve etc., should all still it belong within the patent covering scope of the utility model.
