Description
Technical field:
The utility model relates to the wind power boosting technical field of supercharging technology particularly zero energy consumption.
Background technique:
Current wind turbine turbocharger is applied among a small circle, and pressurized effect is very surprising, because it belongs to " zero energy consumption " work, and the comprehensively universal just matter of time of this technology.Relevant wind power boosting technology, early stage, the patent No. be GB 2147356A (hereinafter referred to as " D1 ") and in recent years the patent No. be the application of CN 201210193224.X (hereinafter referred to as " D2 "), all give the method realizing wind power boosting, comparatively speaking, the structure that D2 more particularly understands turbine and the problem how making pressurized machine normally work under solving the husky sleety weather of dirt, thus completing the transformation of wind power boosting from theory to practicality, current application is mainly using D2 scheme as source.
In existing zero energy consumption supercharging technology, concrete detailed description be there is no to the structure of wind-drive device and the relation of pressurized effect, only make a kind of statement of abstractness, as D2 scheme being expressed as to collection air port in its claims: " 1. a turbo charging installation, it is characterized in that, comprise: wind-drive device, described wind-drive device is tubular, comprise the first opening and the second opening that lay respectively at described wind-drive device two ends, and by air-flow path that described first opening and described second opening couple together for guiding air-flow to flow through, the cross-section area of described air-flow path reduces along with extending from described first opening towards described second opening, " (CN 201210193224.X claim Section 1) and D1 scheme only show general shape and the air flow direction of wind-drive device with diagram, the wind-drive device that D1 scheme provides is that wind-drive device is divided into three parts: first portion is " entrance part ", second portion is " intermediate portion ", Part III is " export department ", obvious D1 requires that the cross-section area of wind-drive device is that slow transition gradual change also at utmost keeps airspeed and pressure with the mutual impact reduced between air-flow, but do not illustrate that in solution progressive formation, wind-drive device volume is excessive, the problem that span is long and cannot implement, because its " entrance part " is long with the span of " export department ", the general traffic tool (automobile) cabin is difficult to layout, practicability becomes to doubt, by contrast, D2 scheme has more practicability.But D2 has also only made the shape restriction of summary-type to wind-drive device, in practical application, we find, if only emphasize that wind-drive device exports the cross-section area size between entrance or only shows its progressive process, and do not take into full account air pressure losing issue in the channel and do not prove the relation between shape design and pressurized effect and practicability that the inner and external structure of wind-drive device should set, so wind power boosting technology will lose using value because effect is inferior in actual applications.Reason is, the relationship principle according to air mass flow and flow velocity: when throughput is constant, conduit cross-sectional area and flow velocity are inverse relation.When second open cross-sectional area is constant in theory, first open cross-sectional area is larger, pressurized effect is better, in practice the ratio of the cross-section area of the first opening and the second opening usually reach more than 10: 1 its pressurized effects just can obviously, this brings again another one problem: due to air-flow linearly direction motion, overwhelming majority air-flow can change direction in the conical pipeline of wind-drive device, if the ratio of the cross-section area of the first open cross-sectional area and the second opening is excessive, theoretical by D1 or D2, will interact in air-flow straight line break-in process: the air-flow of obliquely flow and straight air stream interweave and impact, pressure is cancelled out each other, and form flow-disturbing phenomenon at the second opening, make the atmospheric pressure value of the second opening far below theoretical value, pressurized effect is not obvious, the difference reducing the first opening and the second open cross-sectional area can reduce windage loss, but because air inflow is little, pressurized effect is lower.And wind-drive device long in D1 has departed from practicability.According in prior art, conical tubular or square taper tubular structure are not departed to the collection air port made designed by the description of wind-drive device, volume is excessive and pressurized effect is undesirable, use value greatly reduces, and we have had been found that this problem in actual applications, urgently to be resolved hurrily.
Summary of the invention:
Wind-drive device described in the utility model, it is characterized in that, when air enters collection air port, gas does not remake straight line break-in in air-flow path, air-flow but enter pressure accumulation portion with equidirectional along arc orbit, and in pressure accumulation portion, circle or make the expansion of pressure accumulation air bag to carry out pressure accumulation, pressure release and voltage supply process, because the gas in collection air port passage is no longer interweaved collision, and gas forms high pressure situation in centripetal force in described circular arc air-flow path progressive formation from large to small, the centripetal acceleration of the gas entered in pressure accumulation portion is enhanced, thus make the gas entering collection air port can keep pressure maximum and promote supercharger impeller High Rotation Speed by exhaust outlet in pressure accumulation portion, pressurized effect is not only made to double, also the volume of wind-drive device is made greatly to be reduced into original 1/10-1/20, greatly improve the practicability of wind power boosting, the comprehensively universal of wind power boosting technology for zero energy consumption is laid a solid foundation by its realization.Be further characterized in that, comprise and being achieved through the following technical solutions:
Described wind-drive device, is characterized in that, it is by collecting air port and pressure accumulating chamber's (gas-storing chamber) two large divisions forms.Cross-section area size and the shape thereof of the cross-section area size of described collection air port first opening and shape and the second opening can be identical, or, any two length of sides be parallel to each other of described first opening side length corresponding with described second opening is identical, make air-flow path between described first opening and the second opening can rectangular shaped or trapezoidal shape, and be no longer confined to taper tubular structure, when air-flow path between described first opening and the second opening is trapezoidal shape, can by add guide plate thus the mutual impact reduced to greatest extent between air-flow to keep full admission pressure, described pressure accumulating chamber, it is characterized in that, it is a kind of worm frame, described pressure accumulating chamber is by large air port, little air port, pressure accumulation portion, exhaust outlet, and the air-flow path composition between large air port and exhaust outlet, wherein, length of side size and the shape of the length of side size in described large air port and shape and described collection air port second opening are consistent, its any two length of sides be parallel to each other of described little air port two length of side sizes corresponding with large air port can be identical, comprise the air-flow path between large air port and little air port, the cross-section area of the air-flow path between described large air port and little air port reduces along with extending from described large air port towards described little air port, be further characterized in that, air-flow path between large air port and little air port can be set up guide plate and pass through to guide air-flow, be further characterized in that, described pressure accumulation portion be a kind of can the cylindrical tube shape structure that circles therein of supplied gas, and have the guiding grain guiding air flow direction, described pressure accumulation portion is communicated with collection air port by the air-flow path between little air port and large air port, and described pressure accumulation portion is communicated with pressurized machine by exhaust outlet.Be further characterized in that, described pressure accumulating chamber, its vertical section amasss the maximum cross-section area that can be greater than collection air port first opening or the second opening, and the cross-section area of the exhaust outlet of described pressure accumulating chamber can be less than, be more than or equal to the cross-section area in described little air port; Described collection air port and described pressure accumulating chamber they can be an overall structure be communicated with, also can be a detachable combined type connectivity structure, and, be further characterized in that: described pressure accumulation portion, it is provided with relief hole, described relief hole controls folding by machinery valve, described relief hole also can use as weep hole simultaneously, and when air pressure is excessive, described machinery valve is opened exhaust, discharged by ponding simultaneously; Be further characterized in that, described pressure accumulating chamber can be both streamlined volute shape, and air-flow can be circled wherein; , be further characterized in that, described pressure accumulating chamber can also be a kind of scalable or can the air bag of opening and closing, is stored or provide pressure by limited expansion meanwhile.Described pressure accumulating chamber is further characterized in that, its inside can be provided with the device for pressure release and draining dust discharge; Described wind-drive device is characterized in that, from described collection air port first opening to the cross-section area of the air-flow path between the exhaust outlet of pressure accumulating chamber be by a process of large → gradual change → little → gradual change → large, after air enters collection air port, enter in pressure accumulating chamber after the pressurization of little air port circle or make the air bag of pressure accumulating chamber to expand to store pressure through the large air port of pressure accumulating chamber, again, the high-pressure air in pressure accumulating chamber enters turbine from exhaust outlet and promotes supercharger impeller work.
Relation " V (flow velocity)=L (flow) ÷ S (conduit cross-sectional area) " according to gas flow rate and conduit cross-sectional area draws: when flow is constant, conduit cross-sectional area is less, and speed is faster, and dynamic pressure is larger.That is, if collection first opening in air port is 10: 1 with the cross-section area ratio of the second opening, so, when throughput is constant, airspeed in theory through the second opening will promote 10 times, the wind speed supposing to enter the first opening is 100km/h, and the spot speed that air-flow is entering the second opening so in theory should reach 1000km/h, according to relation P (the kn)=V of bernoulli's equation whether about pressure and speed
2(m/s) ÷ 1600 calculates, and its atmospheric pressure value produced rises to 0.47 barometric pressure from initial 0.0047 barometric pressure, and atmospheric pressure value skyrockets 100 times, but made by D1 or D2 scheme wind-drive device out its to the utilization ratio of wind-force less than 30%, efficiency is very low, main cause is to account for the overwhelming majority at the gas of the inner break-in in collection air port, the air-flow of straight line motion produces very large impact each other with the mass air flow of both sides diagonal movement in collection air port, air pressure is caused to be consumed in a large number before acting on pressurized machine, and it is excessive owing to collecting break-in in air port, a large amount of gas produces very large flow-disturbing phenomenon in the second opening portion branch, be similar to bottleneck effect, only way installs the guide plate of some additional to reduce the cross action between gas in inside, collection air port, but this utilization ratio that just improve a little wind-force, because for the collection air port that break-in is excessive, unless guide plate is enough intensive otherwise air-flow break-in the causes pressure loss is difficult to change all the time, and except the too intensive cost except increasing wind-drive device of guide plate, also or can not to solve the collection air port bodily form excessive and reduce the problem of practicability.We solve this puzzlement difficult problem for many years well by wind-drive device being divided into collection air port and pressure accumulating chamber's two parts, the no longer tapered tubular structure in collection air port, collection air port but can be rectangular shape, make the air pressure entering collection air port can not be subject to any loss, and when gas enters circular movement, it is consistent in the moving direction in each point face, again because centripetal acceleration is in existence, atmospheric pressure lost is very little, thus ensure that the utilization ratio of pressurized machine to wind-force reaches surprising more than 90%, be technically that road has been paved in the all-round popularization of the wind power boosting technology of zero energy consumption.
Beneficial effect:
Problem and the effect thereof of wind-drive device solution described in the utility model are as follows:
1, the problem that the wind-drive device bodily form is excessive, install difficulty is solved
Because D1 and D2 document has only made the description of abstractness to wind-drive device, the shape of the wind-drive device can imagined according to this description does not break away from tubular structure that is conical or square taper (pyramid), because its span is excessive, in concrete practice, occur layout difficulty, even can only be exempted from by force the situation of installation by the outward appearance changing the traffic tool, practicability is restricted; Wind-drive device described in the utility model, volume and profile lighter and small and exquisite, perfection solves an above-mentioned difficult problem, the shape and structure of wind-drive device is made more to enrich and rationalize, greatly improve ease for use, mean that the installation of wind turbine turbocharger is followed one's bent more, practicability is stronger, be easier to popularize in an all-round way.
2, the problem that wind power utilization rate is low is solved
The wind-drive device of taper tubular, not only volume is bigger than normal, span is long, layout is difficult, and the air-flow intertexture imported from different directions is impacted, pose a big pressure loss, according to measuring and calculating, by the wind-drive device of D1 or D2 conceptual design, air-flow enters from first opening (entrance part) of wind-drive device until flow out from the second opening (export department), atmospheric pressure lost is more than 60%, especially when gas pours into the second opening (entrance part) at a high speed, produce very large flow-disturbing phenomenon, make turbosupercharger very low to the utilization ratio of wind-force; Wind-drive device described in the utility model, the air-flow entering collection air port first opening is made to keep from start to finish not interfereing with each other between same trajectories motion, air-flow on each point face, and after being pressurizeed by pressure accumulating chamber, come together in the work of exhaust outlet promotion pressurized machine, it up to more than 90%, efficiently solves a difficult problem for the traffic tool low speed supercharging deficiency using wind power boosting to the utilization ratio of wind-force.
3, the problem that wind-drive device is difficult to standardized production is solved
Wind power boosting Technique Popularizing is more than 2 years, standardized production is subject to the restriction of wind-drive device always, because press scheme or the imagination of D1 or D2, due to wind-drive device second opening connect with pressurized machine suction port, its size and pressurized machine air inlet port size consistent, under the prerequisite ensureing pressurized effect, wind-force can only be adjusted by wind-drive device first opening, global shape and size are difficult to change, the installation of different vehicle is caused to need to formulate different design standards, and the bodily form is excessive, product cost and installation cost are increased greatly and to promote difficulty very big.The realization of wind-drive device described in the utility model, makes wind-drive device no longer be confined to taper tubular structure, not only allows the standardized production of wind-drive device become a reality, and also will the pressurized effect of wind power boosting device be made to have risen to a brand-new high level.

Embodiment:
Below by embodiment, the installation of wind-drive device described in the utility model, pressure accumulation principle and outstanding practicability effect thereof are described:
First, we first illustrate D1 and D2 scheme Problems existing in prior art by legend, to contrast the different technologies feature of wind-drive device described in the utility model existence more clearly.
Fig. 3 is the imagination according to D1 scheme, it is divided into three parts wind-drive device: air input part 11, intermediate portion 12, portion 13 of giving vent to anger, portion 13 of wherein giving vent to anger is connected with pressurized machine 6, can find out, the cross-section area of air input part 11 is more much larger than the cross-section area in portion 13 of giving vent to anger, for reducing inlet loss, the air-flow path of air input part 11 to the portion of giving vent to anger 13 can only be extended, gradually become by pipeline section and keep or effectively promote airspeed, but pay the cost that the wind-drive device bodily form is too large, be difficult in practice implement.Fig. 1 is the imagination according to D2 scheme, wherein wind-drive device 7 is without the transition of " intermediate portion ", but directly from the first opening 1 to the second opening 8 break-in, although the distance of the first opening 1 and the second opening 8 has diminished, but therefrom find out, straight air stream and oblique line air-flow on the right side of air-flow path 3 and left side 2 mutually impact, the flow velocity of a large amount of gas is caused to weaken, and the gas of obliquely flow 4 to produce with the position on right side 5 and middle air flow and impacts and become flow-disturbing on the left of the suction port of pressurized machine 6, has seriously undermined intake velocity and suction pressure.Visible, by the original imagination of D2, the practicability of wind-drive device is not strong, and D1 loses use value substantially because the bodily form is excessive.Fig. 2 adds guide plate 10 for collecting air port during we put into practice on the basis of D2 scheme, therefrom find out, after increasing guide plate, cross action between gas reduces, find in practice that pressurized effect obviously promotes, its effect is much stronger than D1 undoubtedly, but therefore wind-drive device also becomes clumsy and adds fabricating cost, the more important thing is, install guide plate additional and just relatively improve suction pressure, but cannot solve the wind-drive device bodily form excessive, troublesome problem is installed, practical effect still has much room for improvement.
Fig. 4 is wind-drive device described in the utility model, and this example Zhong Ji air port 14 and pressure accumulating chamber 15 are detachable fabricated structures, after described collection air port 14 and pressure accumulating chamber 15 combine as shown in figure 12, described collection air port is similar to Fig. 5, Fig. 6, the length of side and the sectional shape of the length of side of Fig. 5 Zhong Ji air port first opening 19 and sectional shape and the second opening 18 are consistent, the rectangular tubular in whole collection air port, and in figure 6, wherein two length of sides of the first opening 19 are greater than two length of sides corresponding to the second opening, make whole collection air port in gradually flat trapezoidal tubular structure, another two length of sides corresponding with the second opening due to the first opening in Fig. 6 are still equal, its air inlet effect is still better than taper tubular structure, as long as install a small amount of guide plate (guide plate 10 as shown in Figure 10) additional, so the air inlet effect of Fig. 6 just with the effect of Fig. 5 quite or even better, design proposal is depending on engine displacement size, by contrast, the collection air port of Fig. 5 can infinitely reduce according to installing the air-flow path needing from the first opening to the second opening in theory, guide plate quantity is then determined depending on the first openings of sizes in collection air port in Fig. 6, and the air-flow path between the first opening to the second opening still can maintain within 5cm, Fig. 4, the pressure accumulating chamber's structure for volute shape that Fig. 7 shows, Fig. 8 is then a kind of air sac type pressure accumulating chamber, after air enters collection air port, store air bag 21 automatic opening and closing of air inflow size needed for motor, when engine valve aperture is little, then pressure accumulating chamber's pressure increase, store air bag to expand, otherwise store air bag then to reduce, air bag pressure accumulating chamber the same with scroll casing type pressure accumulating chamber can be lossless maintain the existence of air pressure and need to provide enough suction pressures in time according to motor, the air outlet 20 of spiral case pressure accumulating chamber and air bag pressure accumulating chamber can optionally be set on any one position of pressure accumulating chamber, air outlet 20 as air bag pressure accumulating chamber can be positioned at 20a, 20b, 20c, the positions such as 20d, Fig. 9 describes the basic shape in collection air port, when the first opening 19 is greater than the second opening 8, guide plate 10 can be installed additional to guide and to make air-flow keep top speed and pressure to enter pressure accumulating chamber, compared with spiral case pressure accumulating chamber, space shared by air bag pressure accumulating chamber is less, be easier to install.Mainly introduce the embodiment of spiral case pressure accumulating chamber wind-drive device herein.
As shown in figure 11, after air enters collection air port 14, gas makes the centripetal circular movement of high speed in pressure accumulating chamber, and the centripetal force that air-flow is formed is conveyed into pressurized machine 6 boundling high-pressure air by air outlet 20 and promotes impeller work, Figure 13 and Figure 14 then further illustrates the flow direction and the pressure accumulation principle of described wind-drive device gas, air-flow path wherein between large air port and little air port can extend in the circular arc of more than 360 degree, as can be seen from Figure 14, after air enters collection air port 14, gas can enter circular arc air-flow path between the large air port 22 of pressure accumulating chamber 15 and little air port 23 with almost identical direction under the guiding of guide plate 10, and form pressure maximum at little air port 23 place, and no matter under any circumstance, the air-flow 24 doing centripetal motion in the air-flow 25 entering little air port and pressure accumulation portion keeps same direction forever, thus ensure that the stability of air pressure to greatest extent.In practice, we are designed to 30: 1 (in fact can be designed as more than 100: 1) the cross-section area in the cross-section area in large air port and little air port usually, according to throughput, flow velocity, relation formula between pressure and conduit cross-sectional area, according to the ratio of pipeline gradual change, when flow is constant (as automobile at the uniform velocity 100km/h), calculate when large air port 22 intake velocity is 100km/h, the airspeed of position, little air port 22 will close to 3000km/h, for more than 2 times of velocity of sound, the pressure produced is more than 4 barometric pressure, but the force value that little air port 22 occurs does not represent the pressure that pressurized machine produces, it only indicates the maximal pressure force value that pressure accumulation portion 26 can accumulate, in practice, because motor ceaselessly consumes suction pressure, so the air pressure in pressure accumulation portion 26 is difficult to be maintained to the highest, when throughput is constant, motor air demand declines, supercharger impeller synchronization declines, at this time the pressure in pressure accumulation portion 26 just can rise, and supercharging impeller synchronization rises when motor accelerates, the pressure in pressure accumulation portion can drop to normal level again, nonetheless, because motor in vehicle traveling process does not stop to convert operating mode, the pressure in pressure accumulation portion all remains on 1.0-1.5 atmospheric pressure (depending on pressure accumulation portion volume) usually, be enough to promote supercharging impeller rotate with the speed more than 30000r/min, be enough to for motor provides effective suction pressure, if do not consider technology and the technological factor of pressurized machine itself, single with regard to described wind-drive device to regard to the utilizing status of wind-force, its suction pressure provided motor is compared with the pressurized effect that produces of the expensive waste gas supercharger of Jia Ge Ang not a halfpenny the worse with complex process.And the wind-drive device that we make according to D2 scheme, when the cross-section area ratio of the first opening and the second opening is 30: 1, when throughput is constant, the atmospheric pressure value that second opening produces only is equivalent to about 10 times of the first opening suction pressure, namely show that original wind-drive device is not enough or be only about 30% to the utilization ratio of wind-force, after installing guide plate additional, atmospheric pressure value can promote about 5% on the original basis, if the ratio of wind-drive device first opening of visible taper tubular and the second open cross-sectional area is excessive, the effect of guide plate is equally very limited.The guiding grain being positioned at pressure accumulation portion 26 inwall and should being provided with is eliminated in present embodiment, the effect of guiding grain is that the air-flow making to circle can advance by set route, position residing for exhaust outlet 22 sets the direction of guiding grain, to a certain degree can promote the output speed of pressure accumulation portion 26 air-flow in theory, but the space because of pressure accumulation portion is designed very little usually, the speed that high pressure draught exports to low pressure direction is natively very fast, the positive role of guiding grain to be embodied in theory, then because the factors such as process costs may ignore the design of guiding grain in practice, do not show at this.Although wind-drive device described in the utility model achieves the maximization to wind power utilization rate, but suction pressure also needs to consider admission line length and pipe diameter size to the impact of motor and considers design and the technological factor of pressurized machine itself in actual applications, if admission line is long or excessive, or there is design deficiency in pressurized machine itself, can weaken or disperse the pressure exported from pressure accumulation portion 26 equally, but this does not belong to the category that this explanation is discussed.
Wind-drive device described in the utility model not only solves the low problem of the utilization ratio of existing wind-drive device to wind-force, therefore and greatly the bodily form of wind-drive device also reduces, as shown in figure 17, we can find out according to the scaling size of actual size, wind-drive device 29 described in the utility model, its size is more than 1/10 of wind-drive device 27 size of D1 scheme (shown in Figure 15), also less much than the wind-drive device 28 of D2 scheme (shown in Figure 16), only take the space that engine bin is very little, illustrate that wind-drive device described in the utility model is in design, production and fixing link all can realize standardization easily, decisive role will be played to the all-round popularization of wind power boosting technology.
