DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0024] See also Figure 1-Figure 7 In an embodiment of the present invention, a gas turbine air intake system with controllable flow rate includes an air intake bin 1 and a plurality of air outlets 10 arranged on one side of the air intake bin 1, and further includes: A flow rate regulating mechanism is installed on the air inlet bin 1 and cooperates with the plurality of air outlets 10, and the flow rate regulating mechanism can change the conductance of the air outlets 10 so as to change the flow rate of the gas when it passes through the air inlet bin 1 and is pumped out from the air outlets 10; There are multiple pipes 11 installed in the air inlet bin 1, and the pipes 11 are connected to the air outlet 10. A filtering mechanism is also provided in the pipe 11, and the filtering mechanism is used to filter the gas entering the pipe 11. An active trigger mechanism is also provided inside the pipe 11. The active trigger mechanism moves when the gas passes through the pipe 11, and can prompt the cleaning mechanism provided in the pipe 11 to perform a cleaning action on the filtered matter.

[0025] Specifically, during actual operation, air enters the air inlet bin 1, then passes through the pipe 11, and then is filtered out of the filter mechanism for foreign matter removal, and then is guided out from the air outlet 10 to form an air transmission path; During the air transmission process, the active trigger mechanism moves, so the active trigger mechanism will drive the cleaning mechanism to reciprocate in the pipe 11, so that the cleaning mechanism cleans the filtered matter attached to the filter mechanism, so as to avoid the air from being unable to pass smoothly due to excessive accumulation of filtered matter on the filter mechanism, thereby causing adverse effects on the normal transmission of air. The filter mechanism has an effective filtering effect on foreign matter in the air, which can effectively ensure that the air participating in combustion and combustion-supporting meets the requirements, so that the gas turbine can work normally; Secondly, in actual use, the flow rate regulating mechanism can be controlled to work, and the flow rate regulating mechanism can change the conductance of the air outlet 10. Therefore, when the air pumping power is constant, the flow rate of the air when it is discharged at the air outlet 10 will change, that is, the smaller the conductance of the air outlet 10, the greater the flow rate when the air is discharged, and vice versa. Therefore, the system can achieve effective control of the air flow rate, which is convenient for controlling the combustion process.

[0026] Please refer again Figure 2 and Figure 7 The flow rate regulating mechanism includes a threaded boosting structure installed on the air inlet bin 1 and a blocking control structure connected to the threaded boosting structure. The threaded boosting structure includes a threaded rod 3 rotatably installed on the air inlet bin 1, a threaded sleeve 4 sleeved on the threaded rod 3 and threadedly connected to the threaded rod 3, and a driving motor 2 installed on the air inlet bin 1. The threaded rod 3 is connected to the output end of the driving motor 2, and the threaded sleeve 4 is connected to the blocking control structure. The blocking control structure includes an assembly frame 6 connected to the threaded sleeve 4 through two connecting arms 5 and a plurality of flow rate regulating members 7 fixed on the assembly frame 6 facing the air outlet 10. The flow rate regulating members 7 are arranged in a cone shape and are adapted to the air outlet 10. A guide arm 8 is also connected to both sides of the assembly frame 6, and a guide plate 9 is arranged on both sides of the air inlet bin 1. The guide arm 8 is slidably fitted with the guide plate 9.

[0027] When the flow rate of air outlet needs to be accelerated, the drive motor 2 is started, and the drive motor 2 drives the threaded rod 3 to rotate in the forward direction. Accordingly, the guide plate 9 and the guide arm 8 act as guides, and the threaded sleeve 4 is threadedly matched with the threaded rod 3. Then, the threaded sleeve 4 drives the assembly frame 6 to move closer to the air inlet bin 1 through the two connecting arms 5, that is, the flow rate regulating member 7 moves toward the inside of the air outlet 10, and the distance between the outer wall of the flow rate regulating member 7 and the inner wall of the air outlet 10 is gradually shortened, and the conduction area through which the air can pass is reduced, so that the passing air can have a speed-up effect; On the contrary, when the flow rate of air outlet needs to be reduced, the driving motor 2 drives the threaded rod 3 to rotate in the opposite direction, so that the flow rate adjusting member 7 moves toward the outside of the air outlet 10, and the distance between the outer wall of the flow rate adjusting member 7 and the inner wall of the air outlet 10 gradually increases.

[0028] Please refer again Figure 4 , Figure 5 as well as Figure 6 The filtering mechanism includes a filter plate 26 fixed in the pipe 11, the filter plate 26 cooperates with the cleaning mechanism, and the cleaning mechanism is arranged on the side of the filter plate 26 away from the air outlet 10; the cleaning mechanism includes a cleaning plate 23 movably arranged on the side of the filter plate 26 away from the air outlet 10, the cleaning plate 23 abuts against the filter plate 26, and is connected to the active trigger mechanism through a reciprocating guide structure.

[0029] The reciprocating guide structure includes two guide rails 21 installed on the inner wall of the pipe 11 and a connecting plate 22 slidably engaged between the two guide rails 21, and the cleaning plate 23 is connected to the connecting plate 22 through multiple sets of elastic support members. The elastic support member includes a connecting column 24 slidably arranged on the connecting plate 22 and a cylindrical spring 25 sleeved on the outer periphery of the connecting column 24, the connecting column 24 is fixed to the cleaning plate 23, and the two ends of the cylindrical spring 25 are respectively connected to the connecting plate 22 and the cleaning plate 23.

[0030] During the air supply process, the active trigger mechanism moves, which will drive the connecting plate 22 to slide back and forth along the two guide rails 21, so that the cleaning plate 23 will reciprocate on the filter plate 26. Therefore, the cleaning plate 23 can wipe off the filtered matter attached to the filter plate 26, so as to avoid the accumulation of too much filtered matter on the filter plate 26, which will cause the air to fail to pass smoothly later, thereby causing adverse effects on the normal delivery of air; It should be emphasized that the cylindrical spring 25 is in a compressed state, so that under the action of the elastic supporting force of the cylindrical spring 25, the cleaning plate 23 can exert a certain pressure on the filter plate 26, thereby ensuring the cleaning plate 23 has the effect of wiping and cleaning the filter plate 26.

[0031] The active trigger mechanism includes a power component installed in the pipeline 11 and two groups of reciprocating swinging structures connecting the power component and the connecting plate 22. The power component includes an assembly plate 12 fixed in the pipeline 11, a fan 13 rotatably installed on the assembly plate 12, and a driven shaft 14 rotatably installed in the pipeline 11. The two ends of the driven shaft 14 are respectively connected to the two groups of reciprocating swinging structures, and the rotating shaft of the fan 13 is connected to the driven shaft 14 through a bevel gear set 15.

[0032] Specifically, the bevel gear set 15 includes a first bevel gear mounted on the rotating shaft of the fan 13 and a second bevel gear mounted on the driven shaft 14 , and the second bevel gear is meshed with the first bevel gear.

[0033] The reciprocating swing structure includes a swing arm 18 rotatably mounted on the inner wall of the pipe 11 through a shaft 17, a transmission telescopic arm 19 slidably fitted with the swing arm 18, and a disc 16 mounted on the end of the driven shaft 14. The transmission telescopic arm 19 is rotatably connected to the connecting plate 22, a boss 20 is fixedly provided at the eccentric part of the disc 16, a strip-shaped through groove 1801 adapted to the boss 20 is provided on the swing arm 18, and the boss 20 passes through the strip-shaped through groove 1801 and is slidably connected to the swing arm 18.

[0034] When air passes through the fan 13, the fan 13 will be caused to rotate, and then the rotating shaft of the fan 13 will drive the driven shaft 14 to rotate through the bevel gear set 15, so that the disc 16 drives the boss 20 to make a circular motion. Correspondingly, the boss 20 slides with the swing arm 18 through the strip groove 1801, causing the swing arm 18 to swing back and forth. During the reciprocating swing of the swing arm 18, the connecting plate 22 is also driven by the transmission telescopic arm 19 to slide back and forth along the guide track 21, so that the cleaning plate 23 can wipe and clean the filter plate 26 reciprocatingly.

[0035] In general, when the system is in operation, air passes through the fan 13, which will cause the fan 13 to rotate. Therefore, the rotating shaft of the fan 13 drives the driven shaft 14 to rotate through the bevel gear set 15, so that the disc 16 drives the boss 20 to make a circular motion. Correspondingly, the boss 20 slides with the swing arm 18 through the strip-shaped through groove 1801, causing the swing arm 18 to swing back and forth. During the reciprocating swing of the swing arm 18, the link plate 22 is also driven to slide back and forth along the guide track 21 through the transmission telescopic arm 19. Therefore, the cleaning plate 23 can wipe off the filtered matter attached to the filter plate 26, so as to avoid the accumulation of too much filtered matter on the filter plate 26, which may cause the air to be unable to pass smoothly later, thereby causing adverse effects on the normal transportation of the air; When the flow rate of air outlet needs to be accelerated, the drive motor 2 is started, and the drive motor 2 drives the threaded rod 3 to rotate in the forward direction. Accordingly, the guide plate 9 and the guide arm 8 act as guides, and the threaded sleeve 4 is threadedly matched with the threaded rod 3. Then, the threaded sleeve 4 drives the assembly frame 6 to move closer to the air inlet bin 1 through the two connecting arms 5, that is, the flow rate regulating member 7 moves toward the inside of the air outlet 10, and the distance between the outer wall of the flow rate regulating member 7 and the inner wall of the air outlet 10 is gradually shortened, and the conduction area through which the air can pass is reduced, so that the passing air can have a speed-up effect; On the contrary, when the flow rate of air outlet needs to be reduced, the driving motor 2 drives the threaded rod 3 to rotate in the opposite direction, so that the flow rate adjusting member 7 moves toward the outside of the air outlet 10, and the distance between the outer wall of the flow rate adjusting member 7 and the inner wall of the air outlet 10 gradually increases.

[0036] As another embodiment of the present invention, a gas turbine air intake method is also proposed, which uses the gas turbine air intake system with controllable flow rate, and includes the following steps: Step 1: air enters the air inlet 1, and foreign matter is filtered out by the filter mechanism, and then the air is discharged from the air outlet 10; Step 2: The air entering the pipe 11 causes the active trigger mechanism to move, and the active trigger mechanism drives the cleaning mechanism to perform a cleaning action on the filtered objects; Step three, the flow rate adjustment mechanism works and moves toward the inside or outside of the air outlet 10, causing the conduction of the air outlet 10 to decrease or increase, thereby increasing or decreasing the flow rate of the air when it is discharged.
