Abstract
The invention relates to a self-circulating hydraulic power generator taking hydraulic energy as the main motive power, wherein a storage battery is adopted as the start power, a small motor is used for driving a small hydraulic pump to output the hydraulic energy, the smaller hydraulic energy is amplified for tens even hundreds times by the means of the power amplifying principle of the hydraulic jack, the amplified hydraulic energy is converted into mechanical energy to drive a large generator for power generation, and except the electric energy used for keeping the continuous operation of the system of the small motor and charging the storage battery, the remaining majority of electric energy is used for outputting.
Description
One, technical field
In existing technical field of generators, its motive force mainly is waterpower, wind-force, firepower and internal-combustion engine equal energy source.Waterpower, wind-force, firepower receive the restriction of natural condition such as dry season, calm spell and coal are in short supply easily.The internal-combustion engine generating wasting of resources is big, cost is high, is not suitable for long-term use.Electric generation with hydraulic energy can be stablized with the least possible energy, suitable electric energy, is a crucial research direction.
Two, background technique
Hydraulic pressure can be a kind of physical energy commonly used, and it is a working medium with liquid, utilizes the pressure of liquid can carry out energy transfer.The hydraulic transmission stable working; Response speed is fast, impact is little, and ability quick starting, braking and frequent switching-over are under the identical condition of output power; Characteristics such as the hydraulic transmission volume is little, in light weight, motional inertia is little, dynamic performance is little, this development to hydraulic system is significant.Hydraulic pressure can be able to transmit bigger power with change distance, with very little power after power amplification, obtain very big hydraulic pressure can, hydraulic jack for example, with very little power can jack-up tens tons weight.
Three, summary of the invention
Self-loopa hydraulic power generator is can be main motive force with hydraulic pressure; Utilize the power amplification principle of hydraulic jack; Micro-machine is driven the less hydraulic pressure of small-sized hydraulic pump output can input hydraulic cylinder promote piston after with its power amplification tens even hundred times; Through mechanical switching device (bent axle of motor, connecting rod), convert the linear reciprocating motion of piston in the oil hydraulic cylinder to rotation motion, through booster engine rotational speed is promoted again; Drive the high-rating generator generating and produce electric energy, the most of electric energy of residue can supply the output use the micro-machine running maintenance system the when electric energy that is produced begins except that confession turned round continuously and charges a battery.
Generator general structure branch: power plant, actuator, power generation system, auxiliary device (with reference to Fig. 3)
Power plant: form by motor and oil hydraulic pump.Effect be by the motor drives oil hydraulic pump to system's pressure oil output, be whole power resources completely, it starts energy is provided by storage battery.
Actuator: form by a plurality of oil hydraulic cylinders and bent axle, connecting rod.It is the energy conversion device that can amplify the pressure that oil hydraulic pump provides and convert into mechanical energy.Its working principle is: when pressure oil gets into oil hydraulic cylinder, in seal container, can equivalently be delivered to the each point of liquid internal according to pascal's principle by the pressure of external force effect generation.Because it is big that the piston in hydraulic cylinder area becomes,, can make big piston produce bigger power by the less power of oil hydraulic pump input.This is the power amplification process of hydraulic pressure ability.
When pressure oil gets into oil hydraulic cylinder 1, promote piston and do straight line motion to lower dead center from last start position, drive crankshaft rotating through connecting rod, every 1/3rd weeks of rotation of bent axle (promptly 120 °) arrive lower dead center and accomplish a piston stroke (Fig. 2).
When arriving lower dead center, meets by connecting rod electro-magnet switch 1SA, electro-magnet switch 1SA outage, and 1. selector valve is cut in-line and is put off till oil circuit; In-cylinder pressure oil returns fuel tank; Electro-magnet switch 2SA energising simultaneously, selector valve repeats above-mentioned working stroke (Fig. 3) 2. with pressure oil input hydraulic cylinder 2.
Three connecting rod necks are 120 ° of separation at circumferencial direction on the bent axle, on bent axle, turn in time of 360 °, have three cylinders to replace work done, and the interval angle of each cylinder work done is 360 °/3=120 °, and the order of each cylinder work done is 1-2-3.When three oil hydraulic cylinders are accomplished a piston stroke successively, one week of crankshaft rotating, produce to change apart from the face work done, accomplish the process (Fig. 1) that hydraulic pressure can convert mechanical energy into.
The speed of crankshaft oily flow control that is stressed, the big more rotating speed of flow is fast more, and the more little rotating speed of flow is just slow more.
Power generation system: constitute by step-up gear and high-rating generator.Because the rotating speed of bent axle is slower, bring up to the speed-changing gear box of generator rated speed to rotating speed so before driving generator, also must add one, be attached to drive generator operation generation electric energy on the generator again.
Auxiliary device: comprise that various valve elements (like relief valve, selector valve, fuel tank etc.) and electrical apparatus element (like storage battery, electronic current device etc.) are used for pressure, flow (speed), direction and electric current, the electric weight of liquid in the controlled hydraulic system, the conversion of voltage, accomplish the operating movement (with reference to Fig. 3) of expection to guarantee each item system.

Five, embodiment
With one 100 kilowatts generators is example; Its rated speed is 1000 rev/mins, before generator, connects a step-up gear, when the lower velocity shaft rotating speed of gear-box is 30 rev/mins; Could guarantee that generator reaches the rated speed normal power generation, it changes apart from calculating:
Q
(changeing distance)=9549 * Pe
(power)/ n
(rotating speed)=9549 * 100/30
=3.183 * 10
4Ox/rice
Look into product sample, with a variable single-acting high pressure vane pump, its working pressure height is 12MPa; Output flow is 25 liters/minute, by one 8 kilowatts motor drives, to the oil hydraulic cylinder input hydraulic pressure oil of 63 millimeters of diameters; Promote piston-advance, this moment, piston thrust was:
F (thrust)=π r
2(area) * Pe (pressure)=3.14 * (6.3/2)
2* 12 * 10
6
=3.7388 * 10
4Ox/rice
Gained thrust is far longer than the required commentaries on classics distance of generator operation.
Working procedure through 100 kilowatts of innings of above calculating is: the miniature motor drive variable list high pressure vane pump output services pressure that is driven 8 kilowatts by storage battery power supply is 12MPa; Output flow is 25 liters/minute a pressure oil; It is 63 millimeters three cylinder pushes piston-advance that pressure oil gets into diameter successively, converts the straight line motion of piston the rotation motion of bent axle into through connecting rod, bent axle, when three oil hydraulic cylinders are accomplished a piston stroke successively; One week of crankshaft rotating; Rotational speed is by the control of pressure oil input flow rate, and bent axle is connected by lower velocity shaft with step-up gear, when the lower velocity shaft rotating speed reaches per minute 30 commentaries on classics; Generator reaches rated speed; Its generated energy is 100 kilowatts/hour, and institute's generated energy is except that supplying 8 kilowatts of small generators to use and to charge in batteries (this moment, storage battery broke off with motor), also remaining nearly 90 kilowatts of eletctric energy (KWE) and supply output to use.
