Fig. 1 is single blade oscillating stroke hydraulic control apparatus erection drawing
From installation drawing as can be seen, this is a blade, by the hydraulic control device of a single-rod piston oil cylinder 6 regulation and control, this hydraulic control device is made up of fuel tank 1, oil pump 2, relief valve 3, one-way valve 4, two-position two-way solenoid valve 5, single-rod piston oil cylinder 6, pipeline 7, steel cable 8, sharf pull bar 9 and support 10.
Fuel tank 1 adopts the most conventional fuel tank, and its profile can be the garden, also can the side of being, and the size of volume computational methods routinely determine that it generally all is installed on the support, but also can be installed on the support 10.
Oil pump 2 adopts general oil pump, and in year, the work number of times of oil pump 2 is gone up at every turn and also had only a few minutes only for several times, so oil pump 2 does not have special requirement.
Relief valve 3 is safety valves, and main effect is to prevent oil pump 2 overloads, guarantees the safety of hydraulic system.
One-way valve 4 and two-position two-way solenoid valve 5 are general parts of standard, and they are also as oil pump 2, and in year, the number of times of work is only for several times, and each work also has only a few minutes, does not therefore also have special requirement.
Single-rod piston oil cylinder 6; it is an one-way cylinder; the external force action that is subjected to is a pulling force; therefore; can select the relatively little double-action single-rod piston oil cylinder of pull bar diameter; two-way cylinder uses as single-acting; it mainly is the lubricated and protection of considering the oil cylinder back cavity; in specified blade oscillating stroke, the piston in the oil cylinder is failure to actuate, in 1 year; the number of times of its work also is limited; as automatic size according to wind-force, the size of stepless regulated blade oscillating stroke, single-rod piston oil cylinder 6 just needs often action.Touched for exempting from the exposed aerial position oxidation corruption of piston rod, go up dirt-proof boot should for piston rod half.Air in ante-chamber and back cavity and the oil pipe should be discharged before 6 work of single-rod piston oil cylinder.
Pipeline 7 is made up of rigidity oil pipe and flexible tubing, generally speaking, fixed oil pipe rigidity oil pipe, the oil pipe that need move is with flexible oil pipe.Because single-rod piston oil cylinder 6, be to be swinging center motion with the support transverse axis, oil pipe from support 10 to single-rod piston oil cylinder 6 ante-chambers and back cavity, should adopt flexible tubing, but the pipeline 7 that connects ante-chamber is oversize, oil cylinder is in oscillating motion, the motional inertia that flexible tubing produces is too big, this can reduce the working life of oil pipe, for overcoming the oversize deficiency of flexible tubing, fix one section rigidity oil pipe in the outside of oil cylinder, with the ante-chamber oil outlet guide to the back cavity oil outlet near, this flexible tubing has just shortened greatly like this.
Steel cable 8, it is the wire rope of using always, the two ends of wire rope sheath and wire rope fastening piece, be processed into rope sling, the rope sling of one end is connected with the earrings of single-rod piston oil cylinder 6 piston rods, the rope sling of the other end is connected with the earrings of sharf pull bar 9 front ends, this is a kind of flexibly connecting, the maximum characteristics that flexibly connect are bring resistance can not for the starting of blade, as piston rod and the sharf pull bar 9 with single-rod piston oil cylinder 6, do to connect movingly, not only the single-rod piston oil cylinder 6, need frequent motion, reduce working life, bring certain resistance also can for simultaneously the starting of blade.
Sharf pull bar 9 is stayed masts that are welded on the sharf, and it and blade place in one plane are control blade oscillating stroke vitals, adopt steel plate to be welded generally speaking.
Support 10 is triangle steel supports, is installed on the support of swing axis front, and the top of tripod is provided with a transverse axis, the back earrings of single-rod piston oil cylinder 6 is installed on the transverse axis, single-rod piston oil cylinder 6 is to be the axle center of left and right sides reciprocally swinging with the transverse axis, is controlling the size of blade oscillating stroke.
In blade oscillating stroke hydraulic control apparatus, the size of the total length of single-rod piston oil cylinder 6 and steel cable 8 is directly proportional with the size of blade oscillating stroke, and the total length of single-rod piston oil cylinder 6 and steel cable 8 is big more, and then blade oscillating stroke is just big more, otherwise then little.In fact the length of steel cable 8 is changeless, the flexible length of regulation and control single-rod piston oil cylinder 6 piston rods, just can regulate and control the total length of single-rod piston oil cylinder 6 and steel cable 8, also just can regulate and control the size of blade pendulum stroke, piston rod stretches out fully, the oscillating stroke of blade just arrives maximum value, piston rod is regained in the oil cylinder fully, and the oscillating stroke of blade just arrives minimum value, the collapsing length of single-rod piston oil cylinder 6 piston rods, can carry out stepless regulated, obviously, blade oscillating stroke hydraulic control apparatus is a kind of blade oscillating stroke hydraulic stepless regulating controller, only, it is little than the stroke adjusting scope of wire rope blade stepless regulation and control device.Owing to the length of single-rod piston oil cylinder 6 and steel cable 8, determined the oscillating stroke of blade, therefore, when apolegamy single-rod piston oil cylinder 6 and steel cable 8, suitably be equipped with its length.
When needs are put into blade on the ground or the water surface, two-position two-way solenoid valve 5 is opened, hydraulic oil in the ante-chamber of single-rod piston oil cylinder 6 communicates with back cavity and fuel tank 1, under leaf weight and swing action of inertia thereof, the piston rod of pulling single-rod piston oil cylinder 6 moves forward, hydraulic oil in single-rod piston oil cylinder 6 ante-chambers is extruded by piston, flow back to the back cavity and the fuel tank 1 of single-rod piston oil cylinder 6 through two-position two-way solenoid valve 5, owing in the loop certain resistance is arranged, blade can drop on the ground or the water surface lentamente, quit work, two-position two-way solenoid valve 5 is closed subsequently.
As the blade of need with the oscillating wind machine, pull-up on the ground or the water surface, when making it to enter working state, fuel primer pump 2, because two-position two-way solenoid valve 5 is closed, hydraulic oil enters the ante-chamber of single-rod piston oil cylinder 6 through one-way valve 4, under the effect of oil pump 2, promote piston and move backward, piston rod is recovered in the piston cylinder, along with up moving of piston, when blade slowly is pulled up to the terminal point of oscillating stroke, oil pump 2 quits work, and after blade was adjusted the angle of attack, blade began proper functioning, in fact, this starting process connects and is used to, and when the blade pull-up, the angle of attack of blade is just adjusted automatically, under the effect of wind-force, blade has just entered working state when the built on stilts or the water surface.
In the blade oscillating stroke hydraulic control apparatus, single-rod piston oil cylinder 6 and steel cable 8 are direct executive components of control blade oscillating stroke size, because the length of steel cable 8 is constant, what in fact control the blade oscillating stroke size is single-rod piston oil cylinder 6.The back earrings of single-rod piston oil cylinder 6 is sleeved on the transverse axis of support 9, single-rod piston oil cylinder 6 is the axle center with the transverse axis, can do the swing of wide-angle, be to be connected between earrings and the sharf pull bar before the piston rod by steel cable 8, this is a kind of flexibly connecting, hinged as changing steel cable 8 into rod member, a kind of exactly rigidity connects movingly.In oscillating wind machine working procedure, swinging of blade involving steel cable 8 swings, and the swing of steel cable 8 is involving the piston rod swing again, and single-rod piston oil cylinder 6 is also with regard to the swing of turning left thereupon.When blade when swinging to the right destination county of oscillating stroke from left to right, single-rod piston oil cylinder 6 and steel cable 8 are stretching by the sharf pull bar, become 180 degree angles, and then the right angle of attack of blade changes the left angle of attack into, the blade swing that begins to turn left from the right side, single-rod piston oil cylinder 6 and steel cable 8 are loose thereupon, single-rod piston oil cylinder 6, because having, the weight of self returns vertical trend, the swing of turning left that continues along with blade, again by relaxed state, past-180 degree angles are developed, and arrive the left side terminal point of oscillating stroke at last between single-rod piston oil cylinder 6 and the steel cable 8.The control of an oscillating stroke of blade is just finished in the reciprocal variation that single-rod piston oil cylinder 6 and steel cable 8 are stretched and relaxed.
Fig. 2 is the control system figure of single blade oscillating stroke hydraulic control apparatus
In control system figure, can find out, hydraulic control system is made up of 3 hydraulic control circuits, the 1st hydraulic control circuit is: the hydraulic oil of fuel tank 1, by pipeline 7 directly and the back cavity UNICOM of single-rod piston oil cylinder 6, hydraulic oil in the hydraulic system, can between the back cavity of fuel tank 1 and single-rod piston oil cylinder 6, flow, the 2nd hydraulic control circuit is: the hydraulic oil of fuel tank 1, by the ante-chamber UNICOM of pipeline 7 through two-position two-way solenoid valve 5 and single-rod piston oil cylinder 6, hydraulic oil in the ante-chamber can not be flowed by two-position two-way solenoid valve 5 and one-way valve 4 sealings, the piston rod of single-rod piston oil cylinder 6 is locked on the position of setting, blade oscillating stroke just is locked on the size of setting, after two-position two-way solenoid valve 5 is opened, the piston of single-rod piston oil cylinder 6, under leaf weight and swing action of inertia thereof, the piston rod of pulling single-rod piston oil cylinder 6 moves forward, hydraulic oil in single-rod piston oil cylinder 6 ante-chambers is extruded by piston, flow back to the back cavity of fuel tank 1 and single-rod piston oil cylinder 6 through two-position two-way solenoid valve 5, piston rod is drawn out, it is big that blade oscillating stroke becomes, the 3rd hydraulic control circuit is: the hydraulic oil of fuel tank 1, manage 7 through oil pump 2 and one-way valve 4 by pipe, ante-chamber UNICOM with single-rod piston oil cylinder 6, because the sealing process of two-position two-way solenoid valve 5, the hydraulic oil of oil pump 2 outputs is through one-way valve 4, enter the ante-chamber of single-rod piston oil cylinder 6, promote piston and move backward, piston rod is retracted backward, blade oscillating stroke diminishes.In the control system of large-scale or superhuge oscillating wind machine, one-way valve 4 and two-position two-way solenoid valve 5 can be selected the electro-hydraulic control valve or the digital control valve of same function for use, to improve the performance of control system.
Fig. 3 is a double-leaf oscillating stroke hydraulic control apparatus control erection drawing
Double-leaf oscillating wind machine is characterized in that 2 blades swing relatively synchronously, and 2 side direction that blade produced go all out to cancel out each other, and make the stable working of oscillating wind machine, on the other hand, have improved the power of wind-driven generator.
The double-leaf oscillating stroke hydraulic control apparatus, with single blade oscillating stroke hydraulic control apparatus, difference, single-rod piston oil cylinder 6 and the steel cable 8 and support 10 of the same specification of a cover how have been, and the ante-chamber and the back cavity of the single-rod piston oil cylinder 6 of second blade, ante-chamber and the back cavity by the single-rod piston oil cylinder 6 of pipeline and first blade links respectively.Because 2 single-rod piston oil cylinders 6 are parallel connection in oil hydraulic circuit, and their specification is identical, hydraulic pressure in 2 single-rod piston oil cylinder 6 ante-chambers is identical, stretching of 2 piston rods is identical with high and low position, and they are synchronization motion oil cylinders, on the other hand, 2 blades are subjected to the restriction of synchromesh gear in the reciprocally swinging uni-drive gear box, blade is made locking phase at work to swing, and therefore, 2 blades are restricting the synchronous of 2 single-rod piston oil cylinders 6 from the outside.
In large-scale or superhuge double-leaf oscillating wind machine, for alleviating the load of reciprocally swinging uni-drive gear box synchromesh gear, can be on 2 horizontal axis that are arranged in parallel of reciprocally swinging uni-drive gear box outside, intersect and twine synchronous wire rope, make it to become the horizontal axis synchronizer, like this, the horizontal axis synchronizer just can be born the load that produces in 2 huge blade backswings, thereby alleviates the load of synchromesh gear.
Oscillating wind machine, double-leaf are one in front and one in back to be installed in 2 swing axiss, and 2 supports 10 are installed in the front of 2 blades respectively, connecting between support 10 and the sharf pull bar 9, are finished jointly by single-rod piston oil cylinder 6 and steel cable 8.
In double-leaf oscillating wind machine, the fuel tank 1 of blade oscillating stroke hydraulic control apparatus, because the supply of 2 single-rod piston oil cylinder 6 hydraulic oil will be provided, its volume should be more greatly.
In the Remote Automatic Control System of oscillating wind machine, computer cpu, data according to instruments such as wind-force measurements, automatically the action of control two-position two-way solenoid valve 5 and oil pump 2, thereby the size of stepless regulated blade oscillating stroke, when when disastrous hurricane arrives, blade is put on the ground or the water surface, stop proper functioning, exempted from blade and damaged, waitd upon hurricane after the past, again automatically with the blade pull-up by hurricane, begin normal oscillating motion, make the oscillating wind machine begin normal power generation again.
Fig. 4 is the control system figure of double-leaf oscillating stroke hydraulic control apparatus
The control system of double-leaf oscillating stroke hydraulic control apparatus, control system with single blade oscillating stroke hydraulic control apparatus, difference is to increase a single-rod piston oil cylinder 6 that is connected in parallel in the control system, the ante-chamber of this single-rod piston oil cylinder 6, ante-chamber by pipeline 7 and another single-rod piston oil cylinder 6 links, its back cavity, link by pipeline 7 and fuel tank, because these 2 single-rod piston oil cylinders, 6 shared control system, therefore the double-leaf oscillating stroke hydraulic control apparatus is identical with working principle with single blade oscillating stroke hydraulic control dress control procedure.
In large-scale and superhuge oscillating wind machine, the quality of two blades is bigger, and is synchronous from outside 2 single-rod piston oil cylinders 6 of restriction with synchromesh gear, more easily causes synchromesh gear to damage, and this just requires 2 single-rod piston oil cylinders, 6 essential strict synchronism.Aspect control loop, should adopt more accurate synchronizing control loop, as the diverter valve synchronizing control loop, the synchronous valve synchronizing control loop, servovalve synchronizing control loop and synchronized cylinder synchronizing control loop, or adopt control loop synchronously such as central computer processor and electro-hydraulic control valve or digital valve etc., 2 single-rod piston oil cylinders 6 are implemented accurate synchronization control.
In blade oscillating stroke hydraulic control apparatus series, divide the up-set type blade oscillating stroke hydraulic control apparatus, with underneath type blade oscillating stroke hydraulic control apparatus two big classes, what introduce previously is the up-set type blade oscillating stroke hydraulic control apparatus, its single-rod piston oil cylinder 6, be arranged on the triangular supports 10 that is higher than sharf pull bar 9, the piston rod of single-rod piston oil cylinder 6 is downward, and the active force of the suffered blade oscillating of piston rod is a pulling force.The underneath type blade oscillating stroke hydraulic control apparatus, be that a whole set of hydraulic control device is arranged on the support that is lower than sharf pull bar 9,2 single-actings or double-action telescopic sleeve pipe type sucking oil cylinder 6, be installed in 2 destination counties of blade oscillating stroke respectively, the front end of its highest point and sharf pull bar 9 touches, thus the control blade oscillating stroke.Single-acting or double-action telescopic sleeve pipe type sucking oil cylinder 6 flexible and height changes, controlling the size of sharf oscillating stroke, the flexible height of stepless regulated single-acting or double-action telescopic sleeve pipe type sucking oil cylinder 6, size that just can stepless regulated blade oscillating stroke, the height of piston rod is constant, and then blade oscillating stroke is also constant.Because the underneath type blade oscillating stroke hydraulic control apparatus, a blade will dispose 2 single-actings or double-action telescopic sleeve pipe type sucking oil cylinder 6, and its control system will be complicated.But adopt existing hydraulic control system technology, just can implement the regulation and control of blade oscillating stroke well.
In the oscillating wind machine, 2 single-actings of underneath type blade oscillating stroke hydraulic control apparatus or double-action telescopic sleeve pipe type sucking oil cylinder 6, be actually a pair of hydraulic jack, as with this to hydraulic jack, make into by oil hydraulic motor or motor-driven screw-jack, they also can normally be regulated and control the oscillating stroke of blade.But underneath type blade oscillating stroke hydraulic control apparatus, in the control procedure of blade oscillating stroke, the weight of blade and swing inertia thereof can produce certain impact force, this impact force can affect to blade, for reducing this influence, should between sharf and travel control device, elastic material be set, to absorb this impact energy.
