Specific embodiment
Below with reference to the attached drawing in the present invention, clear, complete description is carried out to the technical solution of the embodiment of the present invention, is shown
So, described embodiment is a part of the embodiments of the present invention, rather than whole embodiments.Based on the implementation in the present invention
Example, those of ordinary skill in the art's every other embodiment obtained without making creative work, is all answered
Belong to the scope of protection of the invention.
In order to facilitate understanding and illustrate, referring to Figure 1 to Figure 7, the present invention provides eccentric slide sheet type gas turbine, structures
It include: load 1, plenum chamber 2, combustion chamber 3, power house 4 and main shaft 5；
The load 1 is propeller, belt pulley, speed reducer or transmission shaft；
The plenum chamber 2 is made of several slide plates, air compression cabin and spindle rotor, several slide plates divide the air compression cabin
Several chambers are cut into, the spindle rotor is mounted on the position of the air compression cabin internal deviation central point, so that the chamber
Volume size is inconsistent, and the side surface of the spindle rotor is uniformly inserted into one end of several slide plates, described in several
The inner wall of air compression cabin described in the equal infinite approach of the other end of slide plate, the air compression cabin leading flank are equipped with air inlet, the air compression cabin
Trailing flank is equipped with gas outlet, and the size of the air compression cabin air inlet is the half of the air compression cabin leading flank size, described
The size of air compression cabin gas outlet is equal with the area size that slide plate described in any two and the air compression cabin side wall surround.With master
Axis rotation, slide plate can slide in sliding slot, and cavity volume also can be with variation, as shown in Figures 2 and 3, with turning for main shaft 5
Dynamic, when the position a moves to the position b, cavity volume starts constantly to become larger, and ambient atmos are constantly entered by air inlet gradually to be become
Big chamber completes breathing process.Simultaneously the position c move to the position d, cavity volume constantly becomes smaller, air compression cabin this region just
End face is hermetic design, and gas pressure intensity constantly increases in chamber, and the region d air compression cabin backside face is opening design, forms plenum chamber
The plenum chamber 2 is discharged by gas outlet in gas outlet, high pressure gas, into the combustion chamber 3；
The combustion chamber 3 is made of burning chamber, spindle rotor, fuel injector, igniter, and the spindle rotor is mounted on institute
The position of combustion chamber chamber internal deviation central point is stated, several described fuel injectors and igniter are mounted on the interior of the burning chamber
On wall, the number of the fuel injector and igniter is the inner wall that four and combination of two are uniformly mounted on the burning chamber
On, the combustion chamber 3 mixes the air that the plenum chamber 2 is sent into the fuel oil that fuel injector sprays, and is lighted by igniter, produces
Raw high temperature and high pressure gas；
The power house 4 is made of several slide plates, power bin and spindle rotor, several slide plates divide the power bin
Several chambers are cut into, the spindle rotor is mounted on the position of the power bin internal deviation central point, so that the chamber
Volume size is inconsistent, and the side surface of the spindle rotor is uniformly inserted into one end of several slide plates, described in several
The inner wall of power bin described in the equal infinite approach of the other end of slide plate, the power bin leading flank are equipped with air inlet, the air compression cabin
Trailing flank is equipped with gas outlet, and slide plate described in the size and any two of the power bin air inlet and the power bin side wall surround
Area size it is equal, the size of the power bin gas outlet is the half of the power bin leading flank size.It is described dynamic
Power room 4 is used to convert the energy of combustion chamber high temperature high pressure gas to the mechanical energy of main shaft rotation.
As shown in Figure 4 and Figure 5, the high temperature and high pressure gas that the combustion chamber 3 generates is entered by the air inlet of the power house 4
The power house 4, since main shaft is eccentrically mounted with power bin, during moving to the position b by the position a, the length of slide plate stretching
Degree becomes larger, and always S2 is greater than S1 to two vane areas in each chamber, and high pressure gas acts on the power above S2 and is greater than work
For the power above S1, the active force resultant force of formation is directed toward main shaft direction of rotation, provides power for main axis and external acting.
When the position c moves to the position d simultaneously, the length that slide plate stretches out is gradually become smaller, and cavity volume constantly becomes smaller, and chamber indoor gas is led to
Cross the gas outlet discharge of the power house 4.The high temperature and high pressure gas in the combustion chamber 4 can act on described calm the anger simultaneously at this time
The air inlet of the gas outlet of room 2 and the power house 4, the 2 inside slide plate of plenum chamber are rotated opposite direction by with the main shaft 5
Active force, but since the power house 4 is identical as 2 radial dimension of plenum chamber, power house 4 described in axial dimension is greater than institute
Plenum chamber 2 is stated, the positive torque that the power house 4 generates can be greater than the opposing torque that the plenum chamber 2 generates, and the two is led altogether
Axis, the plenum chamber 2 can be forced by the main shaft 5 is that spindle rotor rotates in the forward direction to the torque that rotates in the forward direction of the power house 4,
To constantly suck air, extra torque is externally done work；
The main shaft 5 sequentially pass through connect it is described load 1, the spindle rotor of plenum chamber 2, combustion chamber 3 spindle rotor and
The spindle rotor of power house 4, the air compression cabin, burning chamber and power bin are the equal cylindrical body of lateral area, the plenum chamber
2, combustion chamber 3, the spindle rotor inside power house 4 are located on the same line.
Working principle: plenum chamber is rotated by multi-stage impeller, and air is continuously sucked from atmosphere and is compressed it；Compression
Air afterwards enters combustion chamber, with the fuel mixing after-combustion of penetrating, becomes high-temperature fuel gas, flows into turbine area expand immediately,
Impeller acting is pushed, turbine wheel is pushed to rotate together with compressor impeller；The acting ability of high-temperature fuel gas after heating is aobvious
It writes and improves, thus gas turbine still has output mechanical work of the complementary work as gas turbine while driving compressor.
Disclosed above is only several specific embodiments of the invention, and still, the embodiment of the present invention is not limited to this, is appointed
What what those skilled in the art can think variation should all fall into protection scope of the present invention.
