Description
Technical field
The present invention relates to it is a kind of being capable of the non-maintaining marine mining engineering conveyer belt of deep diving.
Background technology
At present, the various specifications diving instruments different from model emerge in an endless stream, wherein the most extensive and ripe motor of purposes
Power-equipment is merely able to the various utensils that adapted is run in air, but can not the various utensils that run under water of adapted, study carefully
Its reason, essentially consists in：
Must be provided with if allowing motor that can work under water waterproof sealing structure (such as：It is by such as rubber or plastics
The sealing ring of various specifications made of the macromolecule flexible material of main body serves as) come resist extraneous water body or high-pressure water body for
Infiltration (water body once contacts the damage that will cause the motor with the rotor of rotation) inside motor, however, the waterproof
The setting of sealing structure can not but resist for the fluid including water and air with the magnitude of molecule therefrom pass through can
Energy：
Bicycle tube with automobile tire is non-aerating for a period of time to use, this is just sufficiently illustrated：It should
Manufactured flexible inner tube or tire based on high molecular material rubber or plastics are can not to resist the air as fluid to divide
What the magnitude of son was therefrom passed through, it is clear that：Based on high molecular material rubber or plastics in manufactured flexible piece or block
Gap between molecule is more than the diameter for forming air molecule, and only air molecule is passed through between the high molecular material molecule
Gap rate can slowly some.
The phenomenon that passing through daily life or experiment can also prove：As the fluid molecule of fluid, equally can also pass through with
The waterproof sealing defence line that manufactured any flexible piece is formed based on high molecular material rubber or plastics, only this pass through
Rate also can slowly some.If --- the deep-fried twisted dough sticks food bought with polybag placement, soon, it can be seen that on deep-fried twisted dough sticks
Oil can be exuded to the outside of the polybag, why human eye can find the phenomenon that oil can leak on the outside of polybag, be
Because as the oil of liquid, belong to the substance for being not easy to volatilization, the oil molecule of the leakage that leaks easily in liquid form can be after
Its form on the outside of polybag that leaks is stayed in continuation of insurance；But it if containing water in polybag, leaks on the outside of polybag
Hydrone can be disappeared in human eye sight in the form of evaporation immediately.
Obviously：Above-mentioned all waterproof sealing technology behaves (all mainly undertake by using entity sealing element
), effective permanent sealing effect can not be realized from the magnitude angle of molecule；It is not difficult to imagine：It is set using such effect
The required underwater adapted dragging motor of any Underwater Engineering of meter also necessarily cannot for good and all continue to work under water or stop
Breath moreover, must periodically hang and pull on bank safeguard (not being repair) with the machine of tearing open for excluding to seep water as main task；If make
With several myriawatts even underwater adapted dragging motor of myriawatts up to a hundred, with regard to this " regular dismounting excludes infiltration and safeguards ", this point is (for the time being
Disregard the influence of diving depth), the caused trouble during its use can not even more be imagined, so that allowing people dare not
Extravagant hopes uses the dragging motor of high-power underwater adapted in permanent Underwater Engineering or permanent underwater utensil again.
Thus：At present, can be diving instruments adapted the underwater adapted dragging motor as described in title of the present invention still
It does not propose or comes out.--- this is required adapted water in people's underwater utensil (including engineering) to be solved by every means always
One big problem of lower dragging motor.
Invention content
The purpose of the present invention：
Exactly in order to thoroughly solve the problems, such as above-mentioned this " big " to be solved and solve the problems, such as this " big " it
The one kind proposed afterwards typically matches the typical forms used in the required underwater conveyer belt of offshore mining " combustible ice " mineral reserve.
The key of the present invention is：
The prior art is just to bypass using above-mentioned " the entity member made based on " rubber or plastic flexible material "
Part " and its " structure of adapted " implement the conventional thinking of waterproof sealing, in addition find other approach and allow the present invention can to realize
It realizes qualifiedly：When placing this invention into underwater continuous firing (including the idle period), regardless of its diving depth
With continuous duration how, the present invention can be allowed to accomplish as described in title of the present invention " being capable of deep diving and nothing
Need to periodically debark and exclude infiltration and safeguard " the underwater dragging motor of (safeguard not equal to repair).If --- it can reach so
Ask, then, no matter power made of underwater dragging motor it is much (such as：Up to a million kilowatts) it is how deep with the depth that can dive under water
(such as：Upper km), it is just all unimportant, at that time, under water utensil (such as：As the present invention underwater conveyer belt) in match
With submersible machine with regard to ery easy.
The features of the present invention：
First, due to forming in " full seal type " complete machine structure of the invention, i.e., the gold formed by metal sealing Isolated Shield
Belong in seal isolation cavity, be all (being used as existing of being realized by non-removable welding procedure between all seaming positions
The soldering reliability for having technology thoroughly solves), moreover, the present invention is with vertical direction and underwater utensil adapted
, this is just to allow the incompressible fluid for being lighter than water that can realize that its jacking external world water body is intended to from top to bottom within the present invention
Internal osmotic pressure or great osmotic pressure (being caused by deep diving) creates condition.
If --- the present invention is given under water horizontal positioned, then, circular axle envelope position is also inevitable in the present invention
Can be horizontal positioned, which will necessarily just be higher than the circular top external world water pressure, then the circle
Lower part external world water body will calmly be penetrated by the axle envelope in the metal sealing isolated chambers of the present invention, and will be in cavity
Fluid squeezes out the present invention from the top of round axle envelope position, and consequence is exactly the corrupted that rotor is allowed to slow down and causes motor, specifically
Reason refers to " two " money in " specific embodiment ".
2nd, due to being filled with fluid between the stator and rotor in the present invention, although relatively to its rotating speed compared with air
Some resistances (can suitably slow down) can be caused, as long as however, the present invention to match to be used in be not very big underwater for speed demand
On utensil, whole giving full play to for electric energy efficiency is not have much influences, is only limitted to the shadow for limiting rotary speed
It rings.
--- what if the high speed torque or low speed torque needed in practical application can be a kind of by such as gear-box
Speed changer realizes that this has become the very ripe prior art to adjust.
3rd, it due to being provided with dedicated oil-filled mouth in the present invention, also, is provided in far from metal sealing isolated chambers
The bottom position at top, just can to open and (fill fluid) the oil-filled mouth that can be closed and (block oil circuit), this can not prevent fluid molecule for this
The ad hoc body (element) of (only rate is unhappy) can be passed through at any time, it is impossible to be formed in above-mentioned metal sealing isolated chambers
The gap of fluid molecule is leaked on periphery or upper position of the fluid other than its bottom or channel creates condition.
--- it is of the prior art, such as the waterproof grommet made of flexible high molecular material and its adapted of immersible pump
Compressing structure, just the periphery in the overall structure of the immersible pump or top, which form, can not prevent fluid (gas or water) molecule
Gap or access (it is unhappy only to pass through rate) more can be penetrated：
Under the compressing of extraneous high-pressure water body, hydrone will necessarily pass through anti-the waterproof sealing element of the immersible pump bottom
Water-stop element enters in submersible pump body, while during extruding, and the air molecule on internal top is allowed to pass through the anti-of top
In the low pressure water body that watertight construction leaks to outside submersible pump body.--- it should be not difficult to find out in the process：It is that the prior art is caused to dive
Water pump is unable to deep diving and must periodically debark carry out the root for excluding the two big defects that infiltration is safeguarded, and：Diving depth is got over
Greatly, then the cycle time for being somebody's turn to do " regular " is shorter.
4th, disposable underwater service life of the invention can depend on the aerial rotation of rotor in the present invention completely
Turn service life (World Famous Brand motor can reach 30 years), producing its of the invention service life according to best material is close to 50 years
Or it is longer, i.e., it is also to be close to 50 years or longer that the present invention, which sets the underwater uninterrupted duration,.--- it is such underwater
Dragging motor is very favorable in the obtaining from underwater installation of support " combustible ice ".

The present invention is formed by being adapted to be disposed at underwater conveyer belt structure with special underwater dragging motor two large divisions：
First, the transmission side of 11 level run of the underwater conveyer belt of vertical driving (particular/special requirement of underwater adapted dragging motor)
Formula：
It allows and is connected in the transverse direction that the vertical vertical helical gear 8 in 6 lower end of shaft is moved forwards with coupling driving horizontal conveying belt 11
The end cross helical gear 9 that idler wheel 10 rotates horizontally is driven as the reversing mode for being mutually perpendicular to toe joint.
2nd, the structure of the underwater dragging motor of adapted：
Including：Conventional structure form by the dragging motor that both rotor 2 and stator 1 of embedded winding are formed by it
Shaft 6 implements torque output；
It is characterized in that：
At least allow rotor 2 or allow rotor 2 and stator 1 by narrow metal sealing Isolated Shield 4 or wide type metal sealing every
Off screen is covered 5 and is surrounded with stereogenic, also, in 4 or wide type metal sealing Isolated Shield 5 of narrow type metal sealing Isolated Shield
Bottom be provided with and can be passed down through the shaft 6 of electric machine shaft gland 7；
4 or wide type metal sealing Isolated Shield of narrow metal sealing Isolated Shield, 5 bottom has through pipe connection or straight
Meet the oil-filled mouth D of setting：
The fluid S being filled in the narrow metal sealing Isolated Shield 4 or wide type metal sealing Isolated Shield S；
All splicing seams that the 4 or wide type metal sealing Isolated Shield 5 of narrow metal sealing Isolated Shield is related to
Gap is all to realize connection by non-removable welding procedure；
--- the fluid S is less than 0 DEG C of low-freezing light oil.
It is explained the main points briefly and the signal of Fig. 1 and Fig. 2 according to above, it should substantially be appreciated that the machine of the present invention
Reason, related keyword particular problem when implementing again to the technology of the present invention below make explanation further below：
First, the present invention relates to " hermetically sealed " type structure problems of metal sealing Isolated Shield cavity：
In narrow metal sealing Isolated Shield 4, only rotor 2 is surrounded wherein, narrow metal sealing isolation
Shielding 4 thickness can take several millimeters magnitude (such as：The thickness of small, medium-sized dragging motor can use 2 millimeters)；Positioned at electricity
The thickness of 4 part of narrow metal sealing Isolated Shield between machine rotor 2 and motor stator 1 can be used 0.1 to 0.2 millimeter, and
And, it is necessary to using non-magnetic metal material and it is preferred that narrow metal sealing Isolated Shield 4 and the inner ring position of motor stator 1
It puts in dismountable close-fitting conjunction state；And in wide type metal sealing Isolated Shield 5, form the width type metal sealing Isolated Shield
5 thickness can be using 2 millimeters thick；Gap between above two seal isolation shielding different parts must use welding procedure
It realizes, and should forbid to occur the phenomenon that rosin joint or dry joint (avoid rosin joint or dry joint technically very ripe).
Since the gap formed between metallic molecule is less than the diameter of air molecule or hydrone, metal sealing every
From the structure that shielding cavity is formed " hermetically sealed " type, air molecule or hydrone can be prevented therefrom to pass through；It is and above-mentioned
The sealing ring or structure of various specifications made of the macromolecule flexible material based on rubber or plastics are absolutely not resistances
Only air molecule or hydrone therefrom pass through.
If some position of the metal sealing Isolated Shield cavity in the present invention is using dismountable nonmetallic rubber
Or the flexible macromolecule sealing material of plastics one kind implements sealing by the fastening of bolt, then, it is not likely to form " complete
The three-dimensional defense line of sealing " type, because it can not possibly prevent air molecule with hydrone from passing through, and only it is possible to pass through rate for it
It can be slow.
If some position of the metal sealing Isolated Shield cavity in the present invention is using dismountable two non-ordinary lights
Sliding metal flat implements sealing by the fastening of bolt, then, the solid that it is also impossible to be formed " hermetically sealed " type is prevented
Line, because, then smooth plane all has " roughness ", it is equally also impossible to that air molecule is prevented therefrom to wear with hydrone
More, only its rate passed through may be slowly.
More than two " if " example fully demonstrate used why in the prior art in its key position it is removable
The above-mentioned sealing element and its structure unloaded can not resist gas molecule or fluid molecule and the reason penetrated in defence line is sealed from it.
So far, it should it is very clear, exactly because the present invention employs crucial simple metal seal cavity and realizes
Oneself " hermetically sealed " type three-dimensional defense line, and the penetration problem that can prevent air molecule and hydrone is ensured with this.
When present invention employs the designing scheme full of fluid, purpose is that：The fluid that will not be compressed is allowed in this hair
Bright inside, premised on itself can never be leaked due to " hermetically sealed " the type defence line of formation, it will be able to prevent it is extraneous even
It is high water body pressure for the osmotic pressure inside the present invention.--- if internal fluid has approach that can leak (obviously
Do not have), then, extraneous high-pressure water body will permeate up into (obviously not from 7 position of axle envelope of metal sealing shielding cavity
May).
2nd, the present invention relates to using internal hydraulically full (fluid S) scheme is allowed the problem of：
In view of knowledge：If original design is exactly to allow in motor that water body can be filled with, then, due to water body
Can be conductive, therefore, water body is great for the rotating speed influence of rotor 2：
One is：Since water body can be conductive, rotor 2 can cause it week to make a circle the counter electromotive force of water body formation when rotating
And the influence that rotor 2 is significantly allowed to slow down is caused, the electromotive efficiency of complete machine can also give a discount；
The second is：Water body will result in the shadow significantly to slow down to rotor 2 in rotor 2 and stator 1 in itself between the two
It rings.--- with air in rotor 2 compared between the two it is self-evident with stator 1.
Therefore, the design of general motor, it is most using allowing rotor 2 with stator 1 under conditions of full of air
Allow rotor 2 can high-speed rotating efficient design scheme, however, rotating speed is caused to become once rotor 2 is allowed to touch water body at this time
Slowly, it causes overcurrent phenomenon and damages motor.
If it is exactly deliberately to employ nonconducting fluid S full of the structure type institute inside motor as the present invention
The motor of design, then, nonconducting fluid S can only cause the rotating speed of rotor what is slowed down between rotor 2 and stator 1
It influences, and much can always be influenced less than the deceleration caused by above-mentioned water..
If when the motor of filling fluid S is exactly the underwater utensil that is run for non-high-speed, such as：It is exactly for adapted
During underwater conveyer belt, then, fluid S is filled with, the influence for the underwater dragging motor is only limited to rotating speed decline, and
Conveyer belt does not require natively quickly to run, and this point conforms exactly to therewith.--- however, at this time once the present invention in fluid
S has changed water body (necessarily by can just form the infiltration of extraneous water body under the premise of the original fluid S in part has been squeezed out) into, that
, the water body of the infiltration can equally cause the motor speed relatively slack-off and finally result in the consequence of motor damage.
--- according to above-mentioned analysis and common knowledge, be not difficult it is small bear, exist between the rotor and stator of dragging motor
It is also different that different media, which influences the rotating speed of rotor,：
If in vacuum state, the speed reduction influence of rotor is not present；
If being filled with air, (air drag influences rotating speed little) minimum for the speed reduction influence of rotor；
If being filled with fluid S, (viscosity of fluid S has an impact rotating speed) bigger than normal for the speed reduction influence of rotor；
If being filled with water body, (viscosity of water body has an impact rotating speed) bigger than normal for the speed reduction influence of rotor, however, right
In rotor speed reduction influence maximum element still since water body can be conductive, rotor causes to lead between rotor and stator when rotated
Electric water body can also charge and (generate counter electromotive force), this is likely to reach significantly degree for the influence that rotor slows down, i.e.,
It is likely to the limited influence for deceleration much larger than above-mentioned water body viscosity.
3rd, the present invention relates to the stator of underwater adapted motor can dismounting and change the problem of：
As shown in Figure 2, both motor stator 1 and rotor 2 are shielded by metal sealing Isolated Shield cavity, once
Comparatively the winding on motor stator 1 being easily damaged goes wrong, need dismounting and change motor stator 1 be it is not all right, only
Entire dragging motor can be changed；However, such dragging motor can bring many convenience in the manufacture of itself,
It is all form with such a structure to cause the prior art overwhelming majority.
As shown in Figure 1, motor stator 1 is isolated with rotor 2 by metal sealing Isolated Shield cavity between the two, is made
Become relative to the motor stator 1 for having surround winding that is easily damaged can independent dismounting and change；Due to such motor knot
Structure is made cumbersome, only has only a few to employ such structure that can replace stator 1 at present, in prior art motor product
Form, however, for as underwater adapted motor (particularly with powerful heavy machine), unlike easy complete machine on the ground
Replace, therefore or the consideration that should should be regarded as a different matter or use the ideal structure for being capable of dismounting and change stator 1 to be appropriate, this together
When be also beneficial to extend service life of the underwater adapted motor body part.
In summary：
In general, motor is a highly developed product, as long as ensuring that rotor 2 therein is in fluid S always
Middle rotary work, then, motor is just less likely to be damaged.Therefore, by the rotor 2 in the present invention be arranged on metal sealing every
Off screen covers intracavitary and does not also just have to worry easily occurring after long-term operation from the problem of damage.--- it is driven by motor drag
Durable instrument, such as：Washing machine, refrigerator and sky wither device, etc., typically up to target adapted prior art dragging motor conduct
The utensil of output component, the maintenance-free disposable adapted service life greatly can be at 15 years or more, and World Famous Brand is then reachable
By 30 years or more, if being produced again using best material, the serious hope maintenance-free disposable adapted service life may be more than
50 years.For this purpose, non-removable welding procedure is employed to implement its " full seal type " in belonging to the present invention of simple products
During structure (prevent product is from carrying out demolition and maintenance), time limit of the people for the present invention disposable service life is not interfered with.
