Description
One: technical field
The utility model relates to the energy and water transportation field.
Two: background technology
One mentions seawave power generation, and people will expect utilizing float to reclaim the method for wave ability, and useful float adds the method for wire rope, pulley recovery wave ability; Useful float and fixedly pillar add the ability method of adopting of pulley; Perhaps build one with float join the vertical bar tooth reclaim wave can methods such as fixed offshore platform, numerous; Yet; These methods all are that a common fault is arranged; That is exactly: manufacturing process complicacy, performance difficulty, maintenance expense remain high, and cost is high, the benefit extreme difference, does not just have great practical value at all; Particularly run into the ebb tidal bulge; Especially to agitate just be not that to flood be exactly to thirst for lunar tide or typhoon, and so stubbornly sticking to old ways in the face of changed circumstances for moody sea is exactly paediatrics simply, does not have great practical value; The present invention utilizes brand new concept with regard to looking for another way: the weight with boats and ships self is carrier, a kind of high efficiency of designing, enough tonnages, low cost, is prone to enforcement, wind and wave resistance, can moves local and generate electricity constant round-the-clock outstanding ton sea wave generator station reliably according to changes of seasons is convenient.
Three: summary of the invention
The ton sea wave generator station.The essence of the utility model is exactly that the power conversion that can hold up numerous million tons wheel becomes electric energy.Its energy is from violently surging waves and wave.
The utility model has utilized Wave energy dexterously, is to convert the Wave energy high efficiency to electric energy or other energy unprecedentedly.And equipment that is utilized and facility and equipment all are the products of some conventional maturations, are that ingenious enforcement is arranged, thereby have saved the load of various device and equipment and the trouble and the risk of safety experiment.
As shown in Figure 1, the key of the utility model is: two boats and ships in front and back are fused with hinge axis, even hinges one-tenth is streamlined from beginning to end with many boats and ships, forms a centipede formula generating fleet, place the bay or the wave mouth of billow; When wave attacks, at first raise first ship A, and second ship B is still on former waterline; Because the upper end of two ships connects together with hinge axis 7; So A is drawn by B and the A fore can upwards be raised, the below between the AB widens apart from meeting, thereby drives a plurality of duplexing high pressure cylinder of working simultaneously 1 work; This moment, the piston of duplexing high pressure cylinder was drawn out, and is as shown in Figure 2; When unrestrained peak arrived ship B, ship A then gets into unrestrained paddy and sinks relatively, and B is by the lifting of unrestrained peak, but since A through hinge axis 7 by the B traction, so the below angle diminishes between the AB, thereby be pressed into the piston of duplexing high pressure cylinder 1 as shown in Figure 3.Hinge axis also can be arranged on boat bottom; Its effect but can increase the difficulty of installation, maintenance, repair too like this, makes and cost of electricity-generating thereby increase; Hinge axis is because throughout the year by sea water immersion simultaneously; Life-span also has on production technology also also to become complicated because will increase the problem of waterproof also not as being installed in the length on top, and equipment cost increases.But still alow, it was the same playing a result of use above no matter hinge axis was located at.Certainly, also often adopt hinge axis hull bottom formula to arrange for the needs of some specific factor.But this is usefulness seldom, and the utility model is not recommended this method for arranging, so manual will not be told and accompanying drawing also will not draw.
Because high pressure cylinder is duplexing, no matter piston is to be pressed into or to be drawn out for it, all in the compressed media acting, and replenishes compressed media, schematic diagram such as as shown in Figure 4 simultaneously.The compressed media of high pressure cylinder can be a hydraulic oil, also can be air, also can be soft water, also can be seawater.
The operating principle of duplex high pressure cylinder is: as shown in Figure 4: existing is that medium illustrates with hydraulic oil: when piston 10 is drawn out when a exercises, this moment, the inlet valve 12 of a end cut out, and draining valve 11 is washed open, and the hydraulic oil in a is through draining valve 11 entering energy storage canisters 4; Meanwhile, the inlet valve 17 among the b is washed open, and the hydraulic oil among the b is in time replenished, because the draining valve among the b 16 is to cut out automatically; Hydraulic oil in the energy storage canister 4 can not be back to b; When piston 10 was pressed into to the operation of b end, the valve working situation in the high pressure cylinder was just opposite at this moment, that is: the draining valve 11 of a cuts out automatically; Inlet valve 12 is washed open; Hydraulic oil in a obtains in time replenishing, and simultaneously, inlet valve 17 cuts out automatically in the b; Delivery valve 16 is washed open, and hydraulic oil gets into energy storage canister 4 through oil exit pipe 18.In a word, no matter piston 10 is pressed into or pulls out, all exportable high-pressure and hydraulic oil of high pressure cylinder.
The course of work of whole energy conversion system is as shown in Figure 5: the medium after bidirectional high-pressure cylinder 1 will compress is pressed into buffering accumulated energy jar 4; Thereby get into hydraulic motor or pressure-air motor 3 again and drive generator 2 work; Generator and energy storage canister are can a plurality of high pressure cylinders public, also can single jar of unit of single cylinder.For reducing cost, the present invention uses multi-cylinder shared.If the compressed media that adopts is the liquid type of hydraulic oil or soft water and so on, just certain delivery air chamber must be arranged in the energy storage canister 4 so, like 6 among Fig. 1, air can be compressed, energy storage because have only.Liquid is very difficult compressed.If have ready conditions, also can on the high mountain on the island or bank, build little reservoir, utilize reservoir to come energy storage, at this moment the compressed media in the high pressure cylinder has been exactly common seawater.This does not lose a well invention yet, and is as shown in Figure 6.But, this just becomes and stubbornly sticks to old ways in the face of changed circumstances, because like this, generating fleet just can not move local because of changes of seasons, and it is motionless honestlyly to be fixed on that place well-behavedly.The utility model also has other a kind of energy collecting method: that makes duplexing high pressure cylinder into two-sided vertical bar gear exactly; Through gear drive, freewheel clutch switching-over, flying wheel buffering, accumulation of energy, at the uniform velocity directly drive work such as generator or other plant equipment, screw and utilize Wave energy with collection; This wave with the combination of vertical bar gear and freewheel clutch can gather transform mode we just with it called after: gear overrunning energy collecting mode so that tell.The utility model only has the key position of innovation character to it: the vertical bar gear of collecting energy draws with switching-over freewheel clutch fundamental diagram, and is as shown in Figure 7, and other conventional part is omitted.The operating principle of gathering commutator is such: when connecting rod is pulled out tooth bar when a direction moves; Tooth bar 23 drives the steel column 27 that N takes turns through the external gear 24 of N wheel, becomes one up to wheel output shaft 25 mutual extrusion with the N wheel, counterclockwise rotates thereby drive 25; This moment, the M wheel was because steel column 27 remains on a relatively large excess room between external gear 24 and the output shaft 25; Rotate so 24 can not drive 25, like this, entire mechanism has only the counterclockwise outputting power of N wheel shaft; Otherwise; When connecting rod advances tooth bar when the b direction moves; Tooth bar 23 drives the steel column 27 that M takes turns through the external gear 24 of M wheel, becomes one up to wheel output shaft 25 mutual extrusion with the M wheel, counterclockwise rotates thereby also drive 25; This moment, the N wheel was because steel column 27 remains on a relatively large excess room between external gear 24 and the output shaft 25; Rotate so 24 can not drive 25, like this, entire mechanism has only the counterclockwise outputting power of M wheel shaft; So no matter two-sided tooth bar is pressed into or pulls out, mechanism is all at outputting power and be the power of a direction; Certainly, also can adopt individual gears adopt can, and with freewheel clutch be arranged in go in the transmission process switching-over; Because principle is the same, so this patent repeats no more.
The unidirectional energy collecting mode of this freewheel clutch also can make ratchet one-way energy collecting mode into, but the unidirectional energy collecting reversing mode of freewheel clutch is durable more than ratchet one-way energy collecting reversing mode, and the more environmental protection of freewheel clutch noiselessness, science.So the utility model does not re-use this original reversing mode of ratchet, no longer illustrates yet and explains.
The used boats and ships of the utility model are less demanding, as long as huge enough tonnages, carry out after the special reinforcing repacking.It can use the various superseded ships after retired; Also can make with steel concrete; Principle is exactly one: enough tonnages, enough solid, and can use hinge on one side that whole hull is promoted fully, if tonnage can also be irritated seawater aboard ship inadequately to increase tonnage.Boats and ships after pouring water simultaneously still are a good extraordinary fish culture field, arrange in the above that again wind-driven generator solar panel and eccentric wheel generator are to catch the ocean natural resource as far as possible.
This generating of the utility model fleet can cast anchor fixing; The antirust wirerope of also available high strength multiply be fixed on some reef small islands or bank stone on; Simultaneously to drive the screw that electronic or gas, liquid motor drives in addition also can be the high pressure sea water rifle to the tail ship, and water under high pressure drives boats and ships and drives effective more than screw; The concrete layout that drives hydraulic giant is: a shower nozzle of falling the ship or screw are arranged in the front, the place ahead of first ship, and shower nozzle of falling the ship or screw are except that ship is used with braking, and be also extremely useful for the installation maintenance of generating ship; About two directions respectively arrange one, be used to turn round and adjust the orientation; The tail ship is arranged a heavy caliber shower nozzle or high-power electric screw, is used for the whole fleet of high-speed driving and advances.Whole fleet can Along with season change and change different places.
The ships that the utility model uses is changeable, and quantity is also the amount doesn't matter, but to require size between fleet not want difference very big as far as possible, otherwise single big ship also is the wasting of resources.
