Detailed description of the invention
The present invention is described in detail by way of example below in conjunction with accompanying drawing.
As it is shown in figure 1, for subtracting the vacuum generating device shaking gyrorotor annular seal space, for making the inside in rotor seal chamber 5 produce vacuum.Subtracting the rotor 4 shaking gyro and be arranged in a rotor seal chamber 5, this rotor seal chamber 5 is wrapped in a framework 6, rotor 4 in rotor seal chamber 5 around the axis of rotation 10 rotation, rotor 4 and rotor seal chamber 5 with framework 6 around precession axis 9 precession.
This vacuum generating device includes cylinder 1 and pipeline 3.
It is provided with piston component in cylinder 1, piston component includes interconnective piston 11 and piston rod 12, the inside of cylinder 1 is divided into the first cylinder chamber 13 and the second cylinder chamber 14 by piston 11, wherein, it is the second cylinder chamber 14 that piston 11 connects the side of piston rod 12, and the opposite side of piston 11 is the first cylinder chamber 13.Cylinder 1 is provided with the first blow vent 15 and the second blow vent 16, and the first blow vent 15 is by the ft connection of the first cylinder chamber 13 with cylinder 1, and the second blow vent 16 is by the ft connection of the second cylinder chamber 14 with cylinder 1.
One end of pipeline 3 connects with the inside in rotor seal chamber 5, and the other end of pipeline 3 is gas outlet 31, and in the present embodiment, the junction of the inside in rotor seal chamber 5 and pipeline 3 one end is provided with filter 8.Pipeline 3 is in series with the first check valve 21 and the second check valve 22 that structure is identical, first check valve 21 and the second check valve 22 are equipped with entrance and exit, the entrance of the first check valve 21 connects with the inside in rotor seal chamber 5, the outlet of the first check valve 21 connects with the entrance of the second check valve 22, and the outlet of the second check valve 22 connects with gas outlet 31.Two check valves are only set in the present embodiment, it is possible to increase other check valves as required.
In the present embodiment, one section of pipeline 3 between outlet and the entrance of the second check valve 22 of the first check valve 21 connects with the first blow vent 15, and now the second blow vent 16 is as the air inlet/outlet being in communication with the outside.It is of course also possible to connected with the second blow vent 16 by one section of pipeline 3 between outlet and the entrance of the second check valve 22 of the first check valve 21, now the first blow vent 15 is as the air inlet/outlet being in communication with the outside.Two schemes all can realize the technical purpose of the present invention, and simply the direction of motion of piston component and air-flow direction change, and technique effect is essentially identical.
Piston rod 12 other end corresponding with piston 11 is provided with a connecting rod 7, and connecting rod 7 is connected with the framework 6 outside rotor seal chamber 5.In the present embodiment, connecting rod 7 is connected with the precession axis 9 of rotor seal chamber 5 external frame 6.
The operation principle of the present invention is as follows:
Illustrate with the technical scheme that the first blow vent 15 in the present embodiment connects with pipeline 3: when framework 6 with ships and light boats wave generation precession time, connecting rod 7 can drive piston component to carry out stretching motion in cylinder 1.
When piston component stretches out in cylinder 1, air in rotor seal chamber 5 enters the first cylinder chamber 13 via the first check valve 21 by the first blow vent 15, air in second cylinder chamber 14 is discharged by the second blow vent 16, first cylinder chamber 13 expands and the second cylinder chamber 14 shrinks, thus realize by rotor seal chamber 5 air extract out.
When piston component is when cylinder 1 contract, outside air is entered the second cylinder chamber 14 by the second blow vent 16, air in first cylinder chamber 13 is discharged from the gas outlet 31 of pipeline 3 via the second check valve 22 by the first blow vent 15, first cylinder chamber 13 shrinks and the second cylinder chamber 14 expands, thus realizing the air extracted out in rotor seal chamber 5 discharged to the external world.
Along with constantly waving of ships and light boats, constantly there is precession in framework 6, so that piston component carries out repeatedly reciprocal stretching motion in cylinder 1, due to the design of check valve, air in rotor seal chamber 5 can continuous must be discharged, and makes to produce in rotor seal chamber 5 certain vacuum.
As described in the embodiment, the present invention has only to several simple parts, and including cylinder, piston component, at least two check valve and pipeline, simple in construction, volume are little, and with low cost；Utilize boats and ships waving under the wave action can realize the technique effect making rotor seal intracavity produce certain vacuum, drive without external energy, energy-conserving and environment-protective.The present invention is applied widely, is applicable to various ships, and main application is small-sized ships.
The several specific embodiments being only the application disclosed above, but the application is not limited to this changes that any person skilled in the art can think of, all should drop in the protection domain of the application.
