[0003] Usually, a flashlight or an endoscope is used to inspect the internal faults of the generator, but it is difficult for the flashlight and the endoscope to inspect some parts inside the generator, and it is difficult to find the fault points. Summary of the Utility Model

[0004] The utility model provides a special tool for inspecting the interior of a generator to solve the problem that it is difficult to observe the narrow space parts of the generator by relying on a flashlight or an endoscope.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0006] A special tool for inspecting the interior of a generator includes a corrugated observation tube. A camera is installed at one end of the corrugated observation tube, and a display screen is connected to the other end. The camera is in signal communication with the display screen;

[0007] A steering device is arranged inside the corrugated observation tube. The steering device includes a plurality of steering ropes arranged circumferentially around the inside of the corrugated observation tube. The free ends of the steering ropes extend out from the end of the corrugated observation tube connected to the display screen, and one end of the steering rope close to the camera is fixed to the inner wall of the corrugated observation tube.

[0008] Further, guiding rings are fixed on some wave crest sections of the inner wall of the corrugated observation tube, and the steering ropes pass through the guiding rings.

[0011] Further, a lighting source is fixed on the connection disc close to the camera, and the camera protrudes from the disc surface of the connection disc.

[0012] Further, the steering rope is an elastic rope, and when the steering rope is in a natural state, the guiding ring at the end of the steering rope abuts against the disk surface of the connecting disk.

[0025] To facilitate the understanding of this application, the following will describe this application more comprehensively with reference to the relevant attached drawings. Embodiments of this application are given in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0026] As Figures 1 to 3 shown, a special tool for inspecting the interior of a generator includes a corrugated observation tube 1. One end of the corrugated observation tube 1 is equipped with a camera 2, and the other end is provided with a display screen. The camera 2 and the display screen are signal-connected. Among them, the display screen and the camera 2 can be connected by wire, and the connection line extends out from the inside of the corrugated observation tube 1; the display screen and the camera 2 can also be connected by wireless Bluetooth, so that the real-time image captured by the camera 2 can be displayed on the display screen to realize the observation of the interior situation of the generator.

[0027] Connection plates 6 are fixed at both ends of the corrugated observation tube 1. A metal protection tube 5 is sleeved outside the corrugated observation tube 1. Both ends of the metal protection tube 5 are also fixed to the connection plate 6. The metal protection tube 5 is a flexible tube, which can be bent and deformed while having hardness. By setting the metal protection tube 5, after the corrugated observation tube 1 extends into the generator, it provides stable support, and thus can control the position and bending of the corrugated observation tube 1; by setting the connection plate 6, the connection between the metal protection tube 5 and the corrugated observation tube 1 is realized.

[0028] A steering device is arranged inside the corrugated observation tube 1. The steering device includes multiple steering ropes 3. The multiple steering ropes 3 are circumferentially arranged inside the corrugated observation tube 1, and the steering ropes 3 are fixedly connected to the end of the corrugated observation tube 1 where the camera 2 is installed. The other ends of the steering ropes 3 extend out from the end of the corrugated observation tube 1.

[0029] A number of holes 61 are circumferentially formed on the disk surface of the connection plate 6 close to the display screen. The number of holes 61 formed is the same as the number of steering ropes 3, and the free ends of the multiple steering ropes 3 pass through the multiple holes 61 in one-to-one correspondence. A pull ring 7 is fixed at the end of the steering rope 3. The diameter of the pull ring 7 is larger than the aperture of the hole 61, so that the free end of the steering rope 3 can be restricted from falling into the corrugated observation tube 1 through the pull ring 7.

[0030] The steering rope 3 is an elastic rope. When the steering rope 3 is in a natural state, the guiding ring 4 at the end of the steering rope 3 abuts against the disk surface of the connecting disk 6. Thus, the 360-degree rotation of one end of the corrugated observation tube 1 provided with the camera 2 can be realized through multiple steering ropes 3, enabling the camera 2 to rotate in all directions. Specifically, after the corrugated observation tube 1 is inserted into the generator, if it is necessary to rotate the camera 2 to observe at different angles of the fixed point, the corresponding steering rope 3 can be pulled, so that the corrugated observation tube 1 bends in the axial direction corresponding to the steering rope 3, thereby realizing the rotation of the camera 2.

[0031] Furthermore, guiding rings 4 are fixed on some wave crest segments of the inner wall of the corrugated observation tube 1. Each steering rope 3 passes through multiple guiding rings 4 along its length direction. The guiding rings 4 are preferably arranged uniformly along the length direction of the steering rope 3. By restricting the position of the steering rope 3 through the guiding rings 4, the steering rope 3 is not easily separated from the inner wall of the corrugated observation tube 1, and thus the rotation direction of the corrugated observation tube 1 can be controlled more accurately through the steering rope 3.

[0032] A lighting source is also fixed on the connecting disk 6 near the camera 2. The lighting source illuminates the shooting area of the camera 2, so that the camera 2 can more clearly capture the situation inside the generator. It should be noted that the camera 2 protrudes from the disk surface of the connecting disk 6.

[0033] The special inspection tool of the present application further includes a steering device 8. The steering device 8 includes a base 81 and a locking member 82. The base 81 is fixed on the generator, and the locking member 82 is installed in the base 81 in a universal rotating manner and is sleeved outside the metal protection tube 5. The locking member 82 further includes a clamp. Through the clamp, the locking of the locking member 82 and the metal protection tube 5 can be realized, so that the metal protection tube 5 and the locking member 82 are fixed; when it is necessary to adjust the connection position between the locking member 82 and the metal protection tube 5, the clamp can be loosened, and the metal protection tube 5 can be dragged to move the metal protection tube 5 relative to the locking member 82, thereby adjusting the depth of the corrugated observation tube 1 entering the generator; after the corrugated observation tube 1 is moved to a suitable position, the corrugated observation tube 1 can be locked by using the locking member 82. Since the locking member 82 is rotationally connected to the base 81, the overall rotation of the corrugated observation tube 1 is more convenient; in cooperation with the steering device, the angle adjustment of the end of the corrugated observation tube 1 is realized, comprehensively enabling the special inspection tool for the inside of the generator of the present application to more flexibly adjust the position and direction in the narrow space inside the generator, and thus realizing a more comprehensive and careful inspection of the inside of the generator.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. 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.
