Description

Technical Field

[0001] The present invention relates to the technical field of gas turbine blade detection, in particular to an endoscope auxiliary device and inspection method for gas turbine blades. Background Art

[0002] When detecting the multi-stage blades of a compressor through an intake volute inside the intake chamber of a gas turbine, due to factors such as the number and intricate arrangement of blades at each stage and the space between adjacent blades, when detecting the blades farther from the intake volute, an aluminum-plastic tube needs to be used for guidance. Because the internal space of the gas turbine is narrow, the distance between blades is small, and the vision is limited, etc., it is difficult to identify the blade stages after the aluminum-plastic tube is inserted. For this situation, the detector often pulls the aluminum-plastic tube back to its original position to confirm the specific position and then inserts it again. However, due to the complexity of the on-site situation and the plastic characteristics of the aluminum-plastic tube, it is also impossible to ensure that the aluminum-plastic tube can be inserted into the same position in the same way, resulting in a significant reduction in detection efficiency. And due to space limitations, the aluminum-plastic tube can often only reach a certain position and cannot move along the blade root to the blade tip. Therefore, it can only be fixed at a certain position, and then the lens is moved and rotated for detection and recording. Therefore, the number of blades that can be detected by this method is small; furthermore, due to a certain space interval between the blades at each stage, the illumination of the probe is weak when photographing the blades, so the clarity of the taken photos is poor; finally, when it is necessary to measure the axial clearance values of the wheel discs and stator vane cascades at each stage, the aluminum-plastic tube and the probe wire need to be tightly fixed for about 10 s. However, due to limited working space, phenomena such as probe jitter often occur, resulting in more time required for the detection in this process and reduced efficiency. Summary of the Invention

Detailed implementation manners

[0027] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the drawings of the specification.

[0028] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Second, the "one embodiment" or "embodiment" referred to herein means a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an embodiment that is separate or selectively mutually exclusive with other embodiments.

[0030] Embodiment 1

[0031] Referring to Figures 1 to 9 , which is the first embodiment of the present invention. This embodiment provides an endoscope-assisted device for gas turbine blades, which includes a main body component 100, which includes a moving seat 101 and a probe wire 102; an auxiliary component 200, which includes a clamping component 201 arranged in the moving seat 101, a moving component 202 arranged on the lower side of the moving seat 101, and a detection component 203 arranged on the side wall of the moving seat 101.

[0032] Specifically, the moving seat 101 is arranged in a square shape with a mouth shape, the probe wire 102 is located inside the moving seat 101, there are four clamping components 201, and the four clamping components 201 are distributed in a circular array. There are five moving components 202. A probe is fixedly installed at the end of the probe wire 102. The cooperation between the probe wire 102 and the probe can detect the gas turbine blades.

[0033] Furthermore, the clamping component 201 includes an electric push rod 201a arranged in the moving seat 101. A locking plate 201b is fixedly connected to the telescopic end of the electric push rod 201a. A driver 201c and a controller 201d are fixedly connected to the inner side wall of the moving seat 101.

[0034] Specifically, the electric push rod 201a is fixedly installed on the inner side wall of the moving seat 101. The electric push rod 201a can push the locking plate 201b towards the probe wire 102 to clamp and fix the probe wire 102. Alternatively, a lead screw can be used, and the lead screw is threadedly connected to the moving seat 101 in an interpenetrating manner. Rotating the lead screw can push the locking plate 201b towards the probe wire 102. However, the staff needs to rotate the lead screw four times and stabilize the angle of the locking plate 201b during the rotation process (the locking plate 201b is rotatably connected to the lead screw to prevent the locking plate 201b from rotating with the lead screw), to avoid the locking plate 201b from deflecting, resulting in the surface of the locking plate 201b in contact with the probe wire 102 not being able to fit the surface of the probe wire 102 and affecting the fixing effect. The operation is cumbersome, and the locking plate 201b cannot be quickly contacted with the probe wire 102, and the probe wire 102 cannot be quickly fixed. The driver 201c is connected to the electric push rod 201a to drive the electric push rod to telescopically push the locking plate 201b. The controller 201d is connected to the driver 201c. The controller 201d is also connected to an external control panel. Referring to Figure 9, the display area of the control panel mainly includes a route setting and operation area, an image display and alarm area, and a coordinate display and calculation area. Signals are sent from the control panel to the controller 201d. After receiving the signals, the controller 201d generates corresponding execution signals according to these signals and sends these execution signals to the driver 201c. After receiving the signals from the controller 201d, the driver 201c performs corresponding operations. This is the prior art and will not be elaborated here.

[0035] During use, information such as the structure, shape, and dimensions of the moving blades, stationary blades, and IGV blades of each stage of the gas turbine, as well as the clearance values between the blades of each stage of the gas turbine, is obtained by querying the gas turbine model data to be detected and imported into the control system by means of photographing and recording. Then, the probe wire 102 is inserted into the moving seat 101 and located between the four locking plates 201b. The four electric push rods 201a are started through the controller 201d and the driver 201c to push the four locking plates 201b towards the probe wire 102 until the four locking plates 201b contact the probe wire 102 and clamp and fix the probe wire 102. Under the action of the four clamping assemblies 201, the probe wire 102 can be firmly fixed on the device, and the four electric push rods 201a are stopped from starting; the distance from the installation position to the probe is recorded by the detection component 203. Then, the information of the gas turbine blades to be inspected is set in the control panel. According to the shape, dimensions, position, and quantity of the gas turbine blades to be detected, the path to be moved is designed, etc. Combining the gas turbine structure and the spacing, dimensions, position, etc. of the blades of each stage of the gas turbine, the moving path of the device suitable for detection can be designed, which can effectively expand the detection range of the gas turbine blades and thus increase the detection accuracy; after the setting is completed, the device is moved through the moving component 202. During the movement of the device, the three-dimensional coordinates passing through the leading edge of the IGV blade are recorded, and based on this, as the device moves, the orientation of the endoscopic micro camera 203b and the position of the entire device can be continuously adjusted to identify more characteristic information of the gas turbine blades, compare them with the blades of the same stage of the gas turbine, and compare them with the blade defect maps pre-input into the control system. When a highly matching area is judged, an alarm message will pop up in the image display and alarm area of the control panel. At the same time, the coordinate display and calculation area will display the position coordinates transmitted by the sensor and calculate the position of the probe on the probe wire 102 according to the position calculation formula, thereby determining the number of stages of the moving blades or stationary blades of the gas turbine, which can avoid the problem of confusing the number of stages of the gas turbine blades by currently inserting an aluminum-plastic tube into the gas turbine interior, enabling the detection personnel to clearly see the detection position during the detection process, improving the detection efficiency of the gas turbine blades. The detection process is compared with the gas turbine blade fault information in real time, which can significantly improve the detection efficiency of the blades and quickly obtain the health status of the blades. By applying the moving component 202, the adjustment of the probe on the probe wire 102 at any position can be satisfied.

[0036] Example 2

[0037] Reference Figures 1 to 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an endoscope-assisted device for gas turbine blades, which includes a moving component 202. The moving component 202 includes a first groove 202a arranged on the lower side of the moving seat 101. A rotating groove 202b is formed on the upper wall of the first groove 202a. A rotating column 202c is rotatably connected to the inner side wall of the rotating groove 202b. A U-shaped member 202d is fixedly connected to the lower side of the rotating column 202c. A rotating column 202e is rotatably connected to the side wall of the U-shaped member 202d. A magnetic ball 202f is fixedly connected to the outer surface of the rotating column 202e. A motor 202g is fixedly installed on the side wall of one of the U-shaped members 202d.

[0038] Specifically, the rotating column 202c is rotatably connected to the moving seat 101 through the rotating groove 202b. The U-shaped member 202d can rotate within the first groove 202a and does not contact the inner side wall of the first groove 202a. The rotating column 202e penetrates through the U-shaped member 202d and is rotatably connected to the U-shaped member 202d. The magnetic ball 202f is fixed at the middle position of the outer surface of the rotating column 202e. The output end of the motor 202g is fixedly connected to the corresponding rotating column 202e. When the controller 201d and the driver 201c drive the motor 202g to start, it can drive the corresponding rotating column 202e and the magnetic ball 202f to rotate, realizing the automatic movement of the device.

[0039] Furthermore, the detection component 203 includes a cable 203a arranged on the side wall of the moving seat 101. An endoscope micro camera 203b is fixedly connected to one side of the cable 203a. A position sensor 203c is fixedly installed on the inner side wall of the moving seat 101.

[0040] Among them, the cable 203a can adjust the angle of the endoscope micro camera 203b. The cable 203a contains a guiding wire harness inside. The principle of adjusting the angle is based on a mechanical system called "push-pull wire", which is also the principle of an endoscope in the prior art. The principle of an endoscope is that the flexible catheter of the endoscope contains multiple slender metal wires or lines. These lines are connected to the lens and the controller 201d. The operator controls on the control panel to change the length of these metal wires or lines, so that the direction and angle of the endoscope micro camera 203b change. This is the prior art and will not be elaborated here.

[0041] In use, in conjunction with Embodiment 1, when it is necessary to move the entire device after the four locking plates 201b fix the probe wire 102, the motor 202g is started through the controller 201d and the driver 201c, so that the corresponding rotating column 202e drives the magnetic ball 202f to rotate, enabling the entire device to move its position through the magnetic ball 202f, meeting the adjustment of any position of the probe on the probe wire 102. At the same time, through the control panel, the cable 203a drives the endoscopic micro camera 203b to adjust the direction and angle, so as to better photograph the combustion turbine blade and provide better lighting for the probe of the probe wire 102, improving the photographing effect and detection effect.

[0042] Embodiment 3

[0043] Refer to Figure 2 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an endoscopic auxiliary device for combustion turbine blades, which includes an auxiliary component 200 and also includes an adsorption component 204. The adsorption component 204 includes a groove two 204a provided on the lower side of the moving seat 101. The upper wall of the groove two 204a is fixedly connected with an electric push rod two 204b, and the telescopic end of the electric push rod two 204b is fixedly connected with a magnet 204c.

[0044] Specifically, four adsorption components 204 are provided, and the four adsorption components 204 are distributed at the four corners of the lower side of the moving seat 101.

[0045] In use, in conjunction with Embodiment 1, if it is necessary to determine the defective area, the electric push rod two is controlled to start through the controller 201d and the driver 201c, so as to move the magnet 204c downward onto combustion turbine components such as blades, disks or rotors, so as to adsorb the entire device at a predetermined position, avoiding the problem that the gap value cannot be measured due to the shaking of the probe wire 102. During the detection, the light of the endoscopic micro camera 203b needs to be adjusted to an appropriate brightness to ensure clear photographing of the endoscopic micro camera 203b and the probe on the probe wire 102. If it is necessary to change the relative position of the probe wire 102 and the device during the detection, the electric push rod two 204b needs to be started to make the magnet 204c away from the combustion turbine component, achieving the purpose of unlocking, and then moving the device to perform the detection work of other combustion turbine blades;

[0046] Relying on the adsorption force of the magnet 204c, the device is fixed on the combustion turbine component, avoiding problems such as poor photographing or measurement effects caused by probe shaking when photographing and measuring the gap value between the combustion turbine disk and the combustion turbine stationary blade, and improving the detection accuracy and photographing or measurement effects.

[0047] Embodiment 4

[0048] Refer to Figures 4 to 7, which is the fourth embodiment of the present invention. Different from the previous embodiment, this embodiment provides a method for an endoscope-assisted device for gas turbine blades, which further includes a steering component 300, which includes a power component 301 provided on the side wall of the moving seat 101, a steering component 302 provided on the upper side of the power component 301 and the rotating column 202c, and a push-pull component 303 provided on the power component 301.

[0049] Further, the power component 301 includes an electric push rod three 301a provided on the side wall of the moving seat 101. The telescopic end of the electric push rod three 301a is fixedly connected with a sliding seat 301b. The side wall of the sliding seat 301b is fixedly connected with a sliding plate 301c. An activity groove 301d is opened in the moving seat 101, and a sliding groove 301e is opened on the lower wall of the activity groove 301d. The steering component 302 includes a rotating block 302a provided on the upper side of the rotating column 202c and the sliding plate 301c. The outer surface of the rotating block 302a is fixedly connected with a rotating plate 302b. The upper side of the rotating plate 302b is fixedly connected with a fixed column 302c. The upper side of the fixed column 302c is fixedly connected with a guiding slider 302d. An arc groove 302e is opened on the upper wall of the activity groove 301d. The push-pull component 303 includes a limiting groove 303a provided on the side wall of the sliding seat 301b. A push-pull seat 303b is slidably connected in the limiting groove 303a. The side wall of the push-pull seat 303b is fixedly connected with a push-pull plate 303c. Two through grooves 303d are opened on the side wall of the push-pull plate 303c.

[0050] Specifically, the electric push rod three 301a is fixedly installed on the side wall of the moving seat 101. The sliding seat 301b is slidably connected with the activity groove 301d. The sliding plate 301c is slidably connected with the sliding groove 301e. The corresponding rotating block 302a is fixedly connected with the rotating column 202c. The corresponding rotating block 302a is rotatably connected with the sliding plate 301c. The guiding slider 302d is slidably connected with the arc groove 302e. There are three push-pull components 303, and the three push-pull components 303 are equidistantly distributed. The corresponding push-pull plate 303c is rotatably connected with the outer surfaces of the two fixed columns 302c corresponding horizontally through the two through grooves 303d. When the push-pull seat 303b pulls the push-pull plate 303c to move left and right, the corresponding fixed column 302c is subjected to the pushing and pulling force of the push-pull plate 303c, which will drive the rotating plate 302b to deflect clockwise (0°≥90°) and counterclockwise (0°≥90°) under the action of the rotating block 302a, the guiding slider 302d and the arc groove 302e. At the same time, the push-pull plate 303c drives the push-pull seat 303b to slide in the limiting groove 303a along with the fixed column 302c and the rotating plate 302b, avoiding the push-pull seat 303b and the push-pull plate 303c restricting the angular deflection of the rotating plate 302b.

[0051] In use, in conjunction with Embodiment 1 and Embodiment 2, when it is necessary to adjust the moving direction of the entire device, the electric push rod three 301a is started through the controller 201d and the driver 201c, so that the sliding seat 301b and the sliding plate 301c move left and right under the action of the moving slot 301d and the sliding slot 301e, so that the pushing and pulling seat 303b drives the pushing and pulling plate 303c to move left and right. When the pushing and pulling plate 303c moves left and right, the corresponding fixed column 302c is subjected to the pushing and pulling force of the pushing and pulling plate 303c and will drive the rotating plate 302b to deflect clockwise (0°≥90°) and counterclockwise (0°≥90°) under the action of the rotating block 302a, the guiding slider 302d and the arc-shaped slot 302e, so as to drive the rotating column 202c to drive the angle deflection of the U-shaped member 202d, so that the magnetic ball 202f deflects at an angle along with the U-shaped member 202d, realizing the angle adjustment of the magnetic ball 202f, enabling the entire device to adjust the moving direction, and further satisfying the adjustment of any position of the probe on the probe line 102 driven by the entire device. At the same time, the pushing and pulling plate 303c drives the pushing and pulling seat 303b to slide in the limiting slot 303a along with the fixed column 302c and the rotating plate 302b, avoiding the pushing and pulling seat 303b and the pushing and pulling plate 303c from restricting the angle deflection of the rotating plate 302b, so as not to affect the adjustment of the moving direction of the entire device.

[0052] Embodiment 5

[0053] This is the fifth embodiment of the present invention. Different from the previous embodiment, this embodiment provides an inspection method, which includes determining the path that the probe line 102 needs to pass according to the product description; threading the probe line 102 into the moving seat 101, and letting the electric push rod one 201a push the locking plate 201b towards the probe line 102 to clamp the probe line 102; moving the probe line 102 into the gas turbine to-be-tested part through the moving component 202; taking pictures of the distance between the inner wall of the gas turbine to-be-tested part and the probe line 102 through the endoscope micro camera 203b; inspecting the gas turbine to-be-tested part through the endoscope micro camera 203b and the probe of the probe line 102; when reaching a special position, the electric push rod two 204b pushes the magnet 204c to move downward and adsorb on the inner wall of the gas turbine intake chamber to keep the shooting of the endoscope micro camera 203b and the probe line 102 stable; and moving the position through the moving component 202 to inspect other positions of the gas turbine to-be-tested part; taking out the probe line 102 after walking through the entire path to complete the detection.

[0054] Importantly, it should be noted that the construction and arrangement of the present application shown in multiple different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who refer to this disclosure should easily understand that many modifications are possible without substantially departing from the novel teachings and advantages of the subject matter described in this application (e.g., the dimensions, scales, structures, shapes and proportions of various elements, as well as parameter values (such as temperature, pressure, etc.), installation arrangements, use of materials, color, orientation changes, etc.).
