[0021] Reference Figure 1-5The utility model provides a turbine guide flow capacity adjustment tool: it includes an outer tube 1, an adjustment structure is provided inside the outer tube 1, and the flow rate is adjusted by the adjustment structure. The adjustment structure is arranged at both ends inside the outer tube 1, and the adjustment structure includes a baffle 3. The baffle 3 is in contact with the inner wall of the outer tube 1 to prevent gas from directly flowing into the equipment through the gap, affecting the flow rate adjustment. The baffle 3 is rotatably connected to a connecting shaft 4, and the outer wall of the connecting shaft 4 is fixedly connected to a blade 5. The outer wall of the connecting shaft 4 is fixedly connected to a gear 6, and the connecting shaft 4 connects the blade 5 and the gear 6. The outer wall of the baffle 3 is fixedly connected to a fixing rod 11, and the outer wall of the fixing rod 11 is fixedly connected to a fixing plate 7. The connecting shaft 4 is rotatably connected to the inside of the fixing plate 7. The diameter of the fixing plate 7 is smaller than the diameter of the baffle 3. The fixed plate 7 is connected to the baffle 3 through the fixing rod 11, and the gas flows into the outer tube 1 through the gap between the blades 5. The outer tube 1 is internally rotatably connected to a rack ring 8, which is engaged with the gear 6. The rack ring 8 is arranged on both sides of the inner part of the outer tube 1. The outer wall of the rack ring 8 is fixedly connected to a shift rod 9, which drives the rack ring 8 to rotate through the shift rod 9, and the rotation of the rack ring 8 drives multiple gears 6 to rotate.

[0022] The inner wall of the outer tube 1 is fixedly connected to a fixed shaft 2, and the outer wall of the fixed shaft 2 is fixedly connected to a baffle 3. The baffle 3 is fixed to the inside of the outer tube 1 through the fixed shaft 2. A circular hole 10 is opened inside the outer tube 1. The circular hole 10 is arranged at both ends of the inner part of the outer tube 1. The circular holes 10 at both ends of the inner part of the outer tube 1 are designed to transport gas. Ten blades 5 are provided, and the blades 5 are provided between the baffle 3 and the fixed plate 7. Two groups of adjustment structures are provided, one group of adjustment structures is used to adjust the inlet flow, and the other group of adjustment structures is used to adjust the outlet flow.

[0023] Working principle: When in use, one end of the outer tube 1 is fixed to the outer wall of the turbine engine, and the other end of the outer tube 1 is fixed inside the equipment to be used. When the turbine engine is working, the air flow enters through the circular hole 10 at one end of the outer tube 1, enters the interior of the outer tube 1 through one set of adjustment structures, and is discharged through another set of adjustment structures. When the gas flow needs to be adjusted, the lever 9 and the rack ring 8 at one end of the air inlet are rotated. The rotation of the rack ring 8 drives the ten gears 6 to rotate, and then drives the connecting shaft 4 and the blades 5 to rotate, so that the gaps between the ten blades 5 are adjusted during the rotation of the blades 5, thereby realizing gas intake flow regulation, and then the lever 9 and the rack ring 8 at one end of the air outlet are rotated to adjust the gaps between the blades 5 at the outlet position, thereby realizing gas outlet flow regulation. The intake flow and outlet flow can be controlled separately according to the usage. When adjusting, it is only necessary to drive the rack ring 8 to rotate by the lever 9. The operation is simple and quick.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
