[0002] Inside the intake chamber of the gas turbine, when inspecting the multi-stage blades of the compressor through the intake volute, due to factors such as the number of blades at each stage and their intricate arrangement, as well as the space between adjacent blades, it is necessary to use an aluminum-plastic tube for guidance when inspecting blades that are farther away from the intake volute. Because the internal space of the gas turbine is small, the spacing between the blades is small, and vision is limited, it is difficult to identify the number of blade stages after the aluminum-plastic tube is inserted. In this case, the inspectors often pull the aluminum-plastic tube back to its original position, confirm the specific position, and then insert it again.
[0003] Due to the complexity of the on-site conditions and the plastic characteristics of the aluminum-plastic pipe, it cannot be guaranteed that the aluminum-plastic pipe can be extended to the same position in the same way, resulting in reduced detection accuracy. In addition, due to limited space, the aluminum-plastic pipe can often only penetrate into a certain position and cannot move along the blade root to the blade top. Therefore, it can only be fixed in a certain position and then detected and recorded by moving and rotating the lens. Summary of the Invention

DETAILED DESCRIPTION
[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.
[0029] Example 1
[0030] Reference Figures 1 to 5 , which is the first embodiment of the present invention, provides a gas turbine blade endoscope auxiliary device, which can realize multi-angle movement of the shell 101 and avoid the plastic characteristics of the aluminum-plastic pipe affecting the inspection effect. It includes an installation component 100, including a shell 101, three first electric telescopic rods 102 arranged on the shell 101, a locking ring 103 arranged on the first electric telescopic rod 102, and a probe line 104 arranged in the locking ring 103; an adjustment component 200, including a leveling component 201 arranged on the shell 101, a rotating component 202 arranged on the shell 101, a gear component 203 arranged on the rotating component 202, a moving component 204 arranged on the gear component 203, and a telescopic component 205 arranged on the moving component 204; a measuring component, including a detection component 206 arranged on the shell 101, a magnetic attraction component 301 arranged on the leveling component 201, and a guide component 302 arranged on the moving component 204.
[0031] Specifically, the locking ring 103 here is combined into a diameter equal to the outer diameter of the probe wire 104. The outer end of the probe wire 104 here is connected to an endoscope. The distance between the center lines of the three first electric telescopic rods 102 is 120°. The extension of the first electric telescopic rod 102 can allow the locking ring 103 to move and clamp the probe wire 104.
[0032] Furthermore, the leveling assembly 201 includes a mounting groove 201a provided on the outer shell 101, a second electric telescopic rod 201b is fixedly connected in the mounting groove 201a, a friction pad 201c is fixedly connected to the telescopic end of the second electric telescopic rod 201b, and a position sensor 201d is fixedly connected to the top of the inner shell 101; the rotating assembly 202 includes four mounting holes 202a provided on the outer shell 101, a rotating shaft 202b is rotatably connected in each of the four mounting holes 202a; the steering assembly includes a mounting bracket 202c fixedly connected to the rotating shaft 202b, a transmission shaft 202d is rotatably connected to the mounting bracket 202c, and a roller 202e is fixedly connected to the transmission shaft 202d.
[0033] Among them, the setting of the friction pad 201c can prevent the second electric telescopic rod 201b from sliding, thereby maintaining the stability of the housing 101. The setting of the position sensor 201d can display the position of the housing 101. The setting of the rotating shaft 202b and the mounting bracket 202c can rotate the mounting bracket 202c to achieve multi-directional movement of the housing 101.
[0034] Preferably, the gear assembly 203 includes a gear 203a fixedly connected to the rotating shaft 202b, a first strip groove 203b is provided on the inner wall of the housing 101, a first slider 203c is slidably connected in the first strip groove 203b, and a tooth plate 203d meshing with the gear 203a is fixedly connected to the first slider 203c; the moving assembly 204 includes a mounting plate 204a arranged on the upper side of the tooth plate 203d, two first oblique openings 204b are provided on the mounting plate 204a, a guide rod 204c is provided in the first oblique opening 204b, the guide rod 204c is fixedly connected to the tooth plate 203d, and the guide rod 204c is fixedly connected to the first cap 204d, and the telescopic assembly 205 includes a receiving groove 205a provided in the wall of the housing 101, a motor 205b is provided in the receiving groove 205a, and the output shaft of the motor 205b A turntable 205c is fixedly connected to the top, and two arc-shaped openings 205d are provided on the turntable 205c. The distance between the two arc-shaped openings 205d and the motor 205b decreases in the counterclockwise direction along the turntable 205c. A horizontal plate 205e is fixedly connected to the mounting plate 204a, and a support rod 205f passing through the arc-shaped opening 205d is fixedly connected to the horizontal plate 205e. A second cap is fixedly connected to the support rod 205f. A second strip groove 205g is provided on the outer shell 101, and a second slider 205h fixed to the mounting plate 204a is slidably connected in the second strip groove 205g. A controller 205i and a driver are fixedly connected to the inner wall of the outer shell 101; the detection component 206 includes a power supply 206a embedded in the outer shell 101, and a cable 206b is provided on the power supply 206a, and a camera 206c is connected to the cable 206b.
[0035] It should be noted that the setting of the first slider 203c and the first strip groove 203b can guide the tooth plate 203d, and the distance between the two first bevels 204b and the second strip groove 205g decreases successively along the direction away from the gear 203a. The setting of the first cap 204d can prevent the guide rod 204c from being separated from the first bevel 204b. The setting of the accommodating groove 205a can retract the motor 205b into the accommodating groove 205a to prevent the motor 205b from being damaged due to collision. The distance between the arc-shaped opening 205d and the motor 205b decreases successively in the counterclockwise direction along the turntable 205c. When the turntable 205c rotates counterclockwise, it can drive the two mounting plates 204a to move toward the middle.
[0036] When in use, first check the manual of the combustion engine cylinder to understand the internal structure of the combustion engine blade, and then let the probe line 104 move inward. Here, the probe line 104 can be sent inward by a power device (motor, push rod, etc.). When the probe line 104 moves inward, it can drive the shell 101 to move inward. When the shell 101 moves inward, multiple second electric telescopic rods 201b move to adjust the positions of the four corners so that the shell 101 can enter the combustion engine blade at a suitable angle. The four rollers 202e roll to move the shell 101, and the camera 206c takes pictures to understand the distance between the probe line 104 and the inner wall of the combustion engine blade. When encountering a bend, only the motor 205b needs to rotate counterclockwise to drive the turntable 205c to rotate counterclockwise. At this time, since the distance between the arc-shaped opening 205d and the motor 205b decreases in sequence along the turntable 205c counterclockwise, it drives the support rod 2 05f moves toward the motor 205b, driving the cross plate 205e to move toward the direction of the motor 205b, thereby driving the mounting plate 204a to move toward the direction of the motor 205b. When the mounting plate 204a moves, it can drive the guide rod 204c at the left end to move left, and the guide rod 204c at the right end also moves left, thereby driving the tooth plate 203d to move left, so that the four gears 203a all rotate counterclockwise, and the four rollers 202e rotate in the same direction at the same time, so that the movement direction of the housing 101 can be changed, realizing multi-directional detection. The power supply 206a here can provide power to the first electric telescopic rod 102, the second electric telescopic rod 201b, the motor 205b, the controller 205i, etc. At the same time, the first electric telescopic rod 102, the second electric telescopic rod 201b, the motor 205b, and the controller 205i can all be remotely controlled. This is existing technology and will not be described in detail here.
[0037] In summary, by setting the adjustment component 200, the inclination angle of the entire shell 101 can be adjusted by adjusting the height of the four corners. At the same time, the setting of the four rollers 202e can change the movement direction of the shell 101, so that it can be adjusted in multiple directions and angles, avoiding the plastic characteristics of the aluminum-plastic tube affecting the inspection effect.
[0038] Example 2
[0039] Reference Figures 1 to 7, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a stabilizing component 300 for the combustion turbine blade endoscope auxiliary device, which solves the problem of how to prevent the housing 101 from shaking and affecting the camera 206c from shooting. The magnetic attraction component 301 includes a circular opening 301a provided on the friction pad 201c, an electromagnet 301b is provided in the circular opening 301a, and an annular inner groove 301c is provided on the roller 202e, and a permanent magnet is embedded in the inner groove 301c. 301d; The guide assembly 302 includes a second bevel 302a arranged on the first bevel 204b at the left end, and the second bevel 302a is an extension of the first bevel 204b. A third bevel 302b is provided on the first bevel 204b at the right end, and the third bevel 302b is symmetrically arranged with the second bevel 302a at the right end. Here, taking the rear end mounting plate 204a as an example, for the front end mounting plate 204a, the third bevel 302b is arranged at the left end, and the second bevel 302a is arranged at the right end.
[0040] Specifically, the setting of the electromagnet 301b here can limit the housing 101 to prevent vibration from affecting the shooting effect of the camera 206c. The setting of the permanent magnet 301d ensures that the housing 101 is close to the bottom to prevent the housing 101 from being suspended in the air.
[0041] During use, when the motor 205b rotates clockwise, it can drive the mounting plate 204a to move away from the motor 205b, so that the gear 203a at the left end rotates clockwise, so that the left rear end wheel moves outward, and at the same time, the gear 203a at the right end rotates counterclockwise, so that the right rear end wheel also moves outward, so that the front and rear wheels form an "eight" shape, and the front and rear wheels on the same side also form an "eight" shape to ensure the stability of the overall shell 101. At the same time, the electromagnet 301b is energized and cooperates with the electric telescopic rod to make the electromagnet 301b fit against the inner wall of the engine cylinder, thereby preventing the shell 101 from shaking and ensuring the stability of the camera 206c when shooting. The setting of the permanent magnet 301d prevents the roller 202e from being suspended in the air.
[0042] In summary, by setting up the stabilizing component 300, when it is necessary to keep the housing 101 stable, the four rollers 202e are rotated by the motor 205b to form an "eight" shape between adjacent ones to ensure that the entire roller 202e does not slide, thereby ensuring the stability of the housing 101. At the same time, the electromagnet 301b is energized to prevent the housing 101 from shaking, thereby ensuring the stability of the camera 206c when shooting.
[0043] Example 3
[0044] This is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an inspection method, which includes determining the path that the probe wire 104 needs to travel according to the product description; passing the probe wire 104 through the locking ring 103 and extending the first electric telescopic rod 102 to clamp the probe wire 104; allowing the probe wire 104 to move into the part to be tested; extending the four second electric telescopic rods 201b to adjust the entry angle; the camera 206c takes a picture of the distance between the inner wall of the gas turbine part to be tested and the probe wire 104; when reaching a special position, the electromagnet 301b is energized and adsorbed on the inner wall of the gas turbine air intake chamber to maintain the stability of the camera 206c shooting; the motor 205b is started, and the roller 202e forms an inclination angle to keep the housing 101 stable; after completing the entire path, the probe wire 104 is removed to complete the inspection.
