With the huge consumption of especially resource, the mankind start to be faced with the great crises of especially resource in 21 century,
As the big country of energy consumption, Chinese festiva crude oil import alreadys exceed 100,000,000 tons, and the yield of domestic onshore oil gas field is kept reluctantly
Stablize, brainstrust estimation is difficult there can be important breakthrough again in a short time.And gas hydrates, you can combustion ice, as a kind of replacement
The energy is especially favored by developed country by countries in the world.
For in the gas hydrates that seabed is formed：In 1 DEG C to 20 DEG C of environment temperature, as long as the depth of water is 300
Rice, that is, reach 30 atmospheric pressures, will form gas hydrates, you can combustion ice mineral reserve；And environment higher than above-mentioned temperature or/
It is less than above-mentioned pressure with environment, the gas hydrate dissociation will be promoted at methane and water.
--- the reserves of combustible ice mineral reserve are 2 times of such as oil combustible mineral reserves in the world, enough population in the world
It uses 1000；Theoretical calculation, 1m3Saturated natural gas hydrate can release 164m at the standard conditions3Methane gas,
And gas hydrates burning only generates CO2And H2O belongs to a kind of rare clean energy.
Extremely abundant combustible ice mineral reserve have been contained in the South Sea seabed of China, however, as other marine sites in the world,
Combustible ice mineral reserve are not extracted, the main reason is that, the cost of winning of combustible ice ore (gas hydrates) is very high,
About 200 dollars/m3；So far, there are many " laboratory " method that people find out, and still, are in the exploratory stage, it is difficult to
Into practical business mining phase that can be on a large scale.
Invention content
The purpose of the present invention is：By the mining type of the open coal mine in atmospheric air, it is direct to be transplanted to seabed surface
The exploitation pattern (method) of the combustible ice mineral reserve contacted with water body.
In order to reach the object of the invention, intend using technology below：
Have：The geologic aspects of combustible ice mineral reserve most common distribution wherein from top to bottom：Seawater is covered in seabed rock stratum table
The combustible ice dew mineral reserve in face；
It is characterized in that：
The seabed combustible ice dew mineral reserve that one, is intended to exploitation by underwater shock vehicle hammer A smash；
Combustible ice fragment that two, are crashed to pieces by the grab bucket digging of excavator B is simultaneously put on underwater conveyer belt C nearby, is connect
The vertical positions collecting and distributing lifting point D for being conveyed to combustible ice dew mineral reserve, and underwater conveyer belt C-terminal will be located at from top to bottom
The combustible ice fragment body row at place, which falls into lifting seal box E, temporarily to be stored；
Three, are waited for will be after seal box E sealings, you can are lifted transport out of mining area at any time；
The running that the underwater shock vehicle hammers A, underwaterr excavator B, underwater conveyer belt C and lifting seal box E into shape is logical
The display of underwater camera F is crossed to be remotely controlled；--- people's long-distance remote control on the water surface, alternatively, people's short distance in submarine
Remote control or supervision；
Underwater shock vehicle hammer A, underwaterr excavator B, underwater conveyer belt C and the lifting seal box E and underwater camera
Head F is to have to accomplish the sealing performance that deep diving can reach, also, be not necessarily to the immersible pump such as the prior art
Periodically from water must exclude the regular maintenance work of infiltration like that；
The waterproof sealing structure with《It being capable of the super km of deep diving and the non-maintaining submarine for allowing fluid to carry out waterproof sealing
Electric propeller propeller)》Patent application technology it is identical.
The features of the present invention：
Since can solve being capable of deep diving and not have to be regular for all underwater utensils in the methods of the invention
From water exclude the regular maintenance work of infiltration, moreover, the action or behavior of underwater all exploitation utensils must by
Effective remote control of the water surface, this is just that the combustible ice mineral reserve of the invention for being carried out commercialization exploitation seabed surface covering create pole
Its advantageous condition.
Specific implementation mode
Necessary explanation is made primarily with respect to the main distinction point of the present invention and the prior art.
Entire obtaining from underwater installation process (majority is located at the seabed surface of super upper km depth) is to be unable to get underwater diver
Direct participation, therefore, the overall process of obtaining from underwater installation of the invention necessarily just be under the premise of nobody is directly involved into
Row.--- for the combustible ice recovery process of submarine surface, exploitation major premise is by being easiest to the topside personnel expected
Come realize or people, the bottom in submarine is remotely controlled nearby to realize for remote control.
Obviously, remote control is to belong to the prior art (not being highly difficult), be most difficult to be can deep diving and again be not necessarily to periodically on
Bank excludes the design of the waterproof sealing principle and its structure for the underwater utensil that infiltration water is safeguarded, the slightly example for a prior art
It can illustrate its difficulty：
For by immersible pump, critical issue of the existing immersible pump due to not resolving its waterproof sealing, general
Best effect can just be will receive leaving the remote underwater use of several meters of the water surface, moreover, must also periodically hang pull on bank tear open machine into
Infiltration in row blowdown pump safeguards (not being the repair after corrupted), " periodically disembarkation is safeguarded " interval time, with immersible pump
Diving depth it is related, just as needing " periodically disembarkation exclude infiltration safeguard " this point, people dare not just extravagantly hope using especially big
Power (such as：Myriawatts up to a hundred) immersible pump be used for Underwater Engineering because the single machine weight of extra heavy immersible pump can not possibly
It is very light, it is difficult to " to hang regularly and pull on the maintenance that bank exclude infiltration ".
--- be exactly generally conventional purposes submarine maximum diving depth be not more than hundreds of meters of depth (less than
500 meters) the order of magnitude, and the submarine of super km is to assist people's direct detection seabed combustible ice mining deposits most important and straight
The utensil connect, at the same be also directly be remotely controlled or supervise exploit submarine surface combustible ice mineral reserve during it is indispensable most important
Underwater Moveable manned utensil.
It is not difficult to find out：Only technically solve it is above-mentioned be related to after the present invention and satisfactory underwater utensil,
It can realize that this solves the commercialization mining problem of common seabed surface combustible ice (at low cost and can produce a profit), for this purpose,
China and countries in the world will be included in commercialization exploitation combustible ice all kinds of matters all as key research projects from the point of view of
It waits for, paving is carried out to make great efforts successfully carry out commercialization exploitation combustible ice on earth after about 20 years (common recognitions of various countries)
Pad.
However, when solving the problems, such as above-mentioned, the following patent of invention applied can be referred to：
《The super km of deep diving and non-maintaining it can allow the submarine electric propeller propeller that fluid carrys out waterproof sealing》(Shen
Please number：Once 201611059867.X) --- if the manned submersible for commercialization combustible ice mining service can come out,
So, the appearance for various other underwater utensils of commercialized services less should be just a problem.Because of waterproof sealing
Principle and its adapted structure it is basically the same.
Obviously, the new operation principle of foregoing invention patent and mating new construction, with the world at present including China
On built according to the top level architecture that conventional principles deliberately design only 12 in order to deep quest purposes and being capable of deep diving
6500 meters of submarine is different (cost is high), and the submarine that such " deliberately " is built is to be difficult to realize commercial use
(must be inexpensive).--- and implement foregoing invention patent (application number：201611059867.X), it will be able to for it is very low at
The locally-made foregoing invention for equally capableing of 6500 meters of deep diving or the conventional diving ship (including detection purposes) for capableing of more deep diving is special
Sharp product creates condition, and the commercial use for as extremely entering combustible ice exploitation early creates condition.
