Description
Technical field
The present invention relates to the Apparatus and method in a kind of Naval Architecture and Ocean Engineering field, specifically, relate to a kind of co-current flow type deepwater current generation system and method.
Background technology
Along with the continuous growth of world energy consumption, and the land and shallow sea petroleum construction of natural gas fields is saturated gradually, and people are extended to the deep-sea with the field of oil and gas development.Though the progress of development of science and technology and ocean engineering makes the mankind constantly make progress in the exploitation of deep-sea ocean engineering, but the various complicated marine environment at deep-sea brings very big difficulty still for the production and the existence of ocean engineering structure, especially deep water stream has different flow velocitys on different depth, is one of main difficulty in the design-build of deep-sea ocean engineering structure.For this reason, need in ocean engineering model test, realize simulation to deep water stream.Promptly in basin test, simulate the big degree of depth, and the flow velocity stream that can constantly change with the degree of depth.Simultaneously, under some extreme environment, need simulation upwelling or sinking, promptly current not only have plane motion in the pond, also have the motion on vertical.The simulation of this stream need with diverse current generating system in the past with make the stream method.
Find through literature search prior art, people such as last month of spring group are published in " simulation of sea environment condition " literary composition on " Chinese ocean platform " 1996 04 phase 191-193 pages or leaves, the current generating system and the method in the existing ocean engineering pond of Shanghai Communications University have been introduced, this make the stream method can making space on the uniform shallow water stream of flow velocity flow field, but when making the section deep water stream of very high surface stream of surface velocity or profile change, need just can finish by the local current generating system of temporary erection is auxiliary.Section flow field simulation in the test of deep water ocean engineering model concentrates on the big flow velocity of shallow section and dark two extreme cases of section even velocity of flow according to the requirement of test.The former requires to produce high flow velocity at surface, pond one deck, and it is less demanding to the flow velocity at place, deep-sea, and the latter requires to locate all to produce the same flow velocity at place, deep-sea and shallow sea, promptly be flow velocity of the same size from the seabed to the sea, the requirement of these two contradictions has proposed very high requirement to current generating system.Through research, adopt simple multilayer outer circulation type to make the stream method and also be difficult to satisfy simultaneously above-mentioned two kinds of requirements.Because the big flow velocity of shallow section requires to have very big power for the stream pump of making of surface course, dark section even velocity of flow then requires the power situation basically identical of making the stream pump of all layers.If adopted all layers all to adopt the identical mode of making the stream ability, has only the requirement of satisfying the two by the height of compaction table surface layer simultaneously.This stream method of making can meet the demands to a certain extent, but the problem of bringing is, when needs are simulated surperficial high flow rate, the stream pump of making of depending merely on the top layer sends power and meets the demands, remainder layer make stream pump can't play a role, the surperficial high flow rate of manufacturing is limited, and when need making the equal uniform flow of the big degree of depth, the top layer make stream pump can't all bring into play power, can only even be lower than the form work of half-power with half-power, it is big to have caused each layer to make stream pump separate unit power like this, the phenomenon of capacity of equipment waste.In further retrieving, not identical or similar as yet bibliographical information with theme of the present invention.

The present invention is achieved by the following technical solutions:
Co-current flow type deepwater current generation system of the present invention is made the stream device by six layers and is formed, and each layer comprises: drive water pump, inlet channel, outlet conduit.Inlet channel, outlet conduit connect the two ends in pond.For reaching and flow purpose, be connected going up most to have and flow pipeline between two-layer inlet and outlet pipe lines and the most following two-layer inlet and outlet pipe lines, and have valve control whether to be communicated with.Inlet channel connects the water inlet end that drives water pump and pond, and outlet conduit is linked the driving water pump by the water side in pond.Between first, six layer of inlet channel and outlet conduit of making the stream device, all be furnished with pipeline and be connected, and control by valve and whether to be communicated with.Between second, five layer of inlet channel and outlet conduit of making the stream device, all be furnished with pipeline and be connected, and control by valve and whether to be communicated with.First and second, five, six layers make on stream inlet channel of device and the outlet conduit all mounted valves, whether be communicated with by valve control.
Co-current flow type deepwater current generation method of the present invention is to adopt above-mentioned current generating system to realize, by and flow the connection effect of pipeline and the control of valve, the energy that water pump is driven carries out different distribution at each interlayer, makes the ability that various different sections flow thereby system is possessed.Specific as follows:
1. when needs are made uniformly big depth section stream in the pond, will and flow ducted valve closing, cut off also stream pipeline.Make the stream device for every layer and drive the current that water pump only is responsible for driving this layer, so just can make more uniform deep water stream.When needing slightly to change the flow rate of water flow section shape,, make the flow velocity of this layer current of its driving change just passable as long as reconcile the rotating speed of each layer water pump.
2. when needs are made more high flow rate on the surface, pond when, by and flow pipeline and bottom is made the stream device drive water pump and partly be connected to the upper strata and make in the pipeline of stream device, drive the top layer current simultaneously, so just can make the more surperficial current of high flow rate.As a same reason, when needs when basin bottom is made more high flow rate, by pipeline the upper strata is driven water pump and partly is connected to bottom and makes in the pipeline of stream device, drive one deck current simultaneously, so just can make the more bottom water flow of high flow rate.
3. when needing to make upwelling (when promptly flowing to the current of the water surface from the bottom), can closing and opening by valve, make current by and flow pipeline and concentrate the inlet channel at the bottom of the pond to enter the pond, and flow out the pond from the outlet conduit at top, offside pond, in the pond, form the current that rise, thereby in the pond, simulate upwelling.As a same reason, in the pond by the closing and opening of valve, make current by and flow pipeline and concentrate from the inlet channel of Chi Ding and enter the pond, and flow out the pond from the outlet conduit of bottom, offside pond, in the pond, form the current that descend, thereby in the pond, simulate sinking.
The present invention is with two-layer power and to one deck, thereby the flow and the power concentration of separate unit water pump are got up to make higher flow velocity by the method for concentrating energy, thereby under the situation that does not increase separate unit power, make higher flow velocity, satisfied the requirement of deep-sea ocean engineering experiment.The current that the present invention also makes by the switch of valve pass in and out the alternate position spike in pond, have proposed to make in the pond method of upwelling or sinking first.The present invention has improved the simulation flow velocity, has reduced equipment manufacturing cost, has reduced energy consumption for ocean engineering experiment research in deep-sea provides crucial technical support and research technique.
