Air pressure realizes that air compression ratio steps up, realizes the efficient conversion of energy；By the inertia of flywheel increase rotation, protect
Angular velocity of rotation and the output torque for demonstrate,proving crankshaft are as uniform as possible；Crankshaft rotation speed is adjusted by speed changer；Compressed sky
Gas is stored by air accumulator, and when air accumulator storage is full or electric load raising has power generation needs, pressure-air can be passed by pipeline
It is defeated to realize power generation by sequence of operations program to gas turbine.
A kind of distributing air compressed energy-storage system of the invention, structure is simple, easy to use, applied widely, especially
It is suitble to the place for not having suitable geographical location to build hydroenergy storage station in flat-bottomed land to use, there is very strong practicability.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of distributing air compressed energy-storage system of the invention.
Fig. 2 is the schematic diagram of windmill of the invention.
Attached meaning marked in the figure is as follows: 1, flywheel, 2, speed changer, 3, crankshaft, 4, connecting rod, 5, level-one force (forcing) pump, and 6, two
Grade force (forcing) pump, 7, three times' lifting pump, 8, check valve, 9, air pipeline.
Specific embodiment
Specific introduce is made to the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the present invention is a kind of distributing air compressed energy-storage system, in the inner casing of device, setting is used for
The flywheel 1 of aggrandizement apparatus inertia, the speed changer 2 of adjustable 3 rotation speed of crankshaft；Flywheel 1 is arranged in series according to this with speed changer 2
On crankshaft 3, successively installation is used for the classification force (forcing) pump of gradually compressed air: level-one force (forcing) pump 5, two at 3 connecting rod of crankshaft, 4 axle journal
Grade force (forcing) pump 6, three times' lifting pump 7, and the piston external diameter of level-one force (forcing) pump 5 and cylinder bore diameter are maximum, two-stage pressurizing pump 6 takes second place,
Three times' lifting pump 7 is minimum.
The cylinder bottom both ends of three force (forcing) pumps are separately connected a check valve 8, only air are allowed to circulate to high-pressure side.
And the check valve 8 of 5 cylinder bottom air inlet side of level-one force (forcing) pump is directly and air communication, gas side passes through check valve 8 and second level out
The air inlet of force (forcing) pump 6 is connected to air pipeline 9；Successively, two-stage pressurizing pumps 6 cylinder bottom outlet ports and three times' lifting pumps
7 cylinder bottom inlet ports are connected to check valve 8, and three times' lifting pumps 7 cylinder bottom outlet ports and is equipped with check valve 8, it is preferred that end
The gas outlet at end is connected to form a complete system again with pylon air accumulator by check valve 8.
Flywheel 1 is linked by the wind wheel (blade) of the windmill of wind blows.
Preferably, the present invention can be set in the pedestal of windmill, and using the pylon of wind-driven generator as air accumulator,
Take full advantage of pylon inner space and reasonable transformation after the reasonable utilization structural strength of pylon, economical rationality,
Securely and reliably.
In actual use:
When extraneous wind-force deficiency, blade rotational speed is slow, and traditional wind can not generate electricity, and this system is due to being only responsible for pressure
Contracting gas can increase torque by speed changer 2 without adjusting frequency come compressed air come energy storage.
When extraneous wind-force abundance, blade normal rotation drives flywheel 1 to rotate with crankshaft 3, and force (forcing) pump compression is empty
Gas.When air accumulator storage is full or electric load raising has power generation needs, pressure-air can be transferred to gas turbine by pipeline
It realizes and generates electricity by sequence of operations program.
When the piston of level-one force (forcing) pump 5 up moves, the air pressure in cylinder is reduced, and outside air is by air inlet and unidirectionally
Valve 8 enters in the cylinder of the maximum level-one force (forcing) pump 5 of internal diameter, the air when piston moves down, in level-one force (forcing) pump 5
It is once compressed, when two-stage pressurizing, which pumps 6 pistons, up to be moved, two-stage pressurizing pumps 6 cylinder pressures and reduces, compressed for the first time
Air is entered by the check valve 8 and connecting tube of 5 outlet side of level-one force (forcing) pump in the cylinder of the lesser two-stage pressurizing pump 6 of internal diameter,
When two-stage pressurizing, which pumps 6 pistons, to be moved down, air is compressed for the second time, when three times' lifting, which pumps 7 pistons, up to be moved, three-level
Air pressure in 7 cylinder of force (forcing) pump reduces, and second of compressed air pumps the check valve 8 of 6 other ends by two-stage pressurizing and connect
Adapter tube enters in the cylinder of the smallest three times' lifting pump 7 of internal diameter, when three times' lifting, which pumps 7 pistons, to be moved down, air third
It is secondary to be compressed, the check valve 8 of 7 outlet ports is pumped finally by three times' lifting and gas outlet enters in pylon air accumulator and stores
Come, realizes energy storage.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the above embodiments do not limit the invention in any form, all obtained by the way of equivalent substitution or equivalent transformation
Technical solution is fallen within the scope of protection of the present invention.
