[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0032] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: a gas turbine air intake device that is easy to clean, including an outer shell 1. First, place the outer shell 1 in a suitable position. The left side of the outer shell 1 is connected with an air intake chamber 3. The inside of the air intake chamber 3 is connected with a mounting plate 4. The right side of the mounting plate 4 is connected with a connecting column 2. Then install the connecting column 2 with the gas turbine. The gas turbine inhales a large amount of air from the surroundings. The outside of the connecting column 2 is rotatably connected with a sleeve 5. The right side of the sleeve 5 is connected with a compressor 7. Start the compressor 7. Under the drive of the compressor 7, the air is compressed to a high pressure state, which can improve the air density and pressure.

[0033] A pressure boosting component is arranged outside the sleeve 5. The pressure boosting component can increase the resistance when air flows inside the outer shell 1. The pressure boosting component includes a plurality of blades 6, so that when air enters the outer shell 1, it contacts the blades 6 outside the sleeve 5. One side of the blade 6 is connected to the outside of the sleeve 5, further increasing the resistance of air flow. Fuel inlets 8 are connected to both the upper and lower sides of the outer shell 1. The left end outside the sleeve 5 is rotatably connected to the inside of the mounting plate 4. At this time, the pressure formed by the air inside the outer shell 1 can remove dirt and deposits in the air inlet passage. During operation, it is driven by the power inside the system to keep the air intake device in a clean state and reduce performance loss.

[0034] Referring to Figures 4 - 5 , a filter plate 9 is detachably connected to the left side of the air intake chamber 3. A plurality of positioning holes 19 are formed inside the air intake chamber 3. After the filter plate 9 is placed inside the air intake chamber 3, the mounting posts 11 are sequentially passed through the inside of the positioning holes 19. The outside of the mounting posts 11 is slidably connected to the inner wall of the positioning holes 19 and placed inside the corresponding mounting posts 11. A plurality of card slots 10 are formed inside the filter plate 9. A plurality of mounting components are slidably connected to the inside of the card slots 10. The mounting components facilitate the installation of the filter plate 9. The mounting components include mounting posts 11. A cavity 12 is formed inside the mounting posts 11. A handle 18 is threadedly connected to the inside of the cavity 12. When the handle 18 is rotated, the bottom of the handle 18 is connected to a spring 13. Under the rotation of the handle 18, the spring 13 is compressed by force inside the cavity 12. The other end of the spring 13 is connected to a sliding post 14. When the spring 13 is compressed, it will absorb external force and generate a reaction force on the sliding post 14.

[0035] The outside of the sliding post 14 is slidably connected to the inner wall of the cavity 12. The bottom of the sliding post 14 is connected to a resisting rod 15, so that the sliding post 14 pushes the resisting rod 15 to move downward. The bottom of the resisting rod 15 contacts the inner wall of the card slot 10. When the bottom of the resisting rod 15 contacts the inner wall of the card slot 10, the outside of the resisting rod 15 is slidably connected to the inner wall of the cavity 12. Limiting slots 16 are formed on both the left and right sides of the bottom of the mounting post 11. The outside of the sliding post 14 will push the beads 17 inside the mounting post 11 to slide outward along the inside of the limiting slots 16. The beads 17 are rotatably connected to the inner wall of the limiting slots 16. When the diameter of the beads 17 is engaged with the inner diameter of the limiting slots 16, the beads 17 can be engaged with the inner wall of the card slot 10. At this time, stop rotating the handle 18, and the filter plate 9 can be installed inside the air intake chamber 3.

[0036] The outer part of the ball bead 17 is rotatably connected to the inner wall of the mounting post 11. The outer part of the sliding post 14 is in contact with the outer part of the ball bead 17. When disassembling, turn the handle 18 again. At this time, the spring 13 is no longer stressed. As the handle 18 moves, the sliding post 14 is pulled upward. The outer part of the ball bead 17 is engaged with the inner wall of the card slot 10. At the same time, the abutting rod 15 retracts into the mounting post 11. The ball bead 17 is no longer squeezed. Pull the mounting post 11 outward. At this time, the ball bead 17 will be squeezed by the card slot 10 and slide into the mounting post 11 along the inner part of the limiting groove 16, and the filter plate 9 can be removed to filter the external air, which is convenient for disassembly and installation and is convenient for later maintenance and cleaning of the filter plate 9.

[0037] During use: First, place the housing 1 in a suitable position. After placing the filter plate 9 into the intake chamber 3, pass the mounting post 11 through the inner part of the positioning hole 19 in sequence and place it into the corresponding inner part of the mounting post 11. At this time, turn the handle 18. Under the rotation of the handle 18, the spring 13 is compressed in the cavity 12. When the spring 13 is compressed, it will absorb the external force and generate a reaction force on the sliding post 14, so that the sliding post 14 pushes the abutting rod 15 downward. When the bottom of the abutting rod 15 is in contact with the inner wall of the card slot 10, the outer part of the sliding post 14 will push the ball bead 17 inside the mounting post 11 to slide outward along the inner part of the limiting groove 16. When the diameter of the ball bead 17 is engaged with the inner diameter of the limiting groove 16, the ball bead 17 can be engaged with the inner wall of the card slot 10. At this time, stop turning the handle 18, and the filter plate 9 can be installed in the intake chamber 3.

[0038] When disassembling, turn the handle 18 again. At this time, the spring 13 is no longer stressed. As the handle 18 moves, the sliding post 14 is pulled upward. At the same time, the abutting rod 15 retracts into the mounting post 11. The ball bead 17 is no longer squeezed. Pull the mounting post 11 outward. At this time, the ball bead 17 will be squeezed by the card slot 10 and slide into the mounting post 11 along the inner part of the limiting groove 16, and the filter plate 9 can be removed.

[0039] Then connect the connecting post 2 to the gas turbine. The gas turbine inhales a large amount of air from the surrounding. Then start the compressor 7. Driven by the compressor 7, the air is compressed to a high pressure state, which can increase the air density and pressure, so that the air contacts the blades 6 outside the sleeve 5 after entering the housing 1, further increasing the resistance of the air flow. At this time, the pressure formed by the air inside the housing 1 can remove the dirt and deposits in the intake duct.

[0040] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
