[0002] A generator is a device that converts mechanical energy into electrical energy. Fixed insulators are generally provided thereon because the stator winding and rotor winding of the generator are usually in a high-voltage state. The fixed insulators can effectively isolate these live components from the machine housing (grounded part) and other non-live components, prevent the occurrence of high-voltage arc discharge and short-circuit faults, and ensure the safe operation of the generator. However, during the operation of the generator, the fixed insulators are prone to dust contamination. Since the dust contains various impurities, it will increase the surface conductivity of the insulators, thereby significantly reducing the insulation performance of the insulators. Therefore, it is necessary to regularly clean the dust on the insulators. However, existing cleaning machines are relatively large in volume because they are equipped with power components, resulting in low maneuverability and thus being not conducive to use in narrow generator sets.

[0025] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the specific embodiments and the drawings.

[0026] The terms used in the present invention are those general terms that are currently widely used in the art in consideration of the functions of the present invention, but these terms can be changed according to the intentions of those of ordinary skill in the art, precedents or new technologies in the art. In addition, specific terms can be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present invention.

[0027] This embodiment provides a cleaning mechanism such as Figure 1 As shown, a fixed insulator and a cleaning blade 11 in contact with the fixed insulator are placed in the cleaning area 41, and the cleaning member 1 is connected to the fixed shell 4 through a mounting base 37 and a mounting sleeve 34 arranged at both ends. Therefore, during the cleaning process, the cleaning member 1 and the cleaning blade 11 can be driven to rotate by the driving member 2 built into the cleaning member 1, thereby cleaning the dust on the surface of the fixed insulator.

[0028] like Figure 2 and Figure 3 As shown, the driving member 2 is disposed in the placement cavity 35 and fixedly mounted with the top of the placement cavity 35, and the output end of the driving member 2 passes through the placement cavity 35 and is equipped with a driving tenon rod 21, as shown in FIG. Figure 3 As shown, the connecting plate 1 32 and the connecting plate 2 33 are provided with corresponding bolt holes, so that the staff can connect the connecting plate 1 32 and the connecting plate 2 33 together by bolts. Figure 4 It can be seen that a driving mortise hole 22 which engages with the driving tenon rod 21 is provided at the center of the connecting plate 32.

[0029] During cleaning, the driving member 2 disposed in the placement cavity 35 will drive the connecting plate 2 33 to move through the mutual engagement of the driving tenon rod 21 and the driving mortise hole 22. Figure 2 It can be seen that the connecting plate 2 33 is fixedly connected to the inner wall of the accommodating chamber 31. Therefore, when the connecting plate 2 33 rotates, it will drive the cleaning member 1 connected thereto to rotate, thereby causing the cleaning blade 11 installed outside the cleaning member 1 to rotate and clean the dust on the fixed insulator. This installation method of installing the driving member 2 inside the cleaning member 1 makes the structure of the entire cleaning mechanism more compact, can reduce the volume of each structure, make the cleaning mechanism lighter and simpler, and is convenient for operation in a narrow space. At the same time, compared with traditional external transmission methods, such as belt transmission or chain transmission, the built-in driving member 2 can avoid multi-stage transmission from occupying too much space, thereby freeing up more space for other components or functional modules of the cleaning mechanism, which is beneficial to the overall design of the equipment. Moreover, the power transmission of the built-in driving member 2 is more direct, which reduces the energy loss in the transmission process, improves the power transmission efficiency, enables the cleaning member 1 to work more efficiently, and increases the cleaning effect. In addition, from Figure 1 It can be seen that a dust collecting member 5 is provided on the fixed shell 4 at a position opposite to the cleaning area 41. Therefore, after the cleaning member 1 cleans the dust on the fixed insulator, the dust collecting member 5 will absorb the dust to prevent it from being adsorbed on other components of the generator set during the falling process, thereby ensuring the normal operation of the generator set.

[0030] like Figure 1 and Figure 2As shown, the connecting end of the mounting sleeve 34 and the fixed shell 4 is provided with a connecting hole 38 connected to the placement cavity 35, and the fixed shell 4 is provided with a connecting hole 39 corresponding to the connecting hole 38. During normal use, the power cord connected to the driving member 2 can extend into the placement cavity 35 through the connecting hole 1 38 and the connecting hole 2 39, and will not affect the normal rotation of the cleaning member 1, thereby ensuring the cleaning work.

[0031] from Figure 2 As can be seen from the figure, the mounting sleeve 34 is arranged in the accommodating chamber 31. During the cleaning process of the device, the inner wall of the accommodating chamber 31 will rotate around the mounting sleeve 34, thereby causing friction with the mounting sleeve 34. In order to avoid wear of the outer wall of the mounting sleeve 34 and the inner wall of the accommodating chamber 31, thereby affecting their service life, in the present embodiment, a friction-reducing sleeve 36 is sleeved between the mounting sleeve 34 and the inner wall of the accommodating chamber 31, and the inner wall and outer wall of the friction-reducing sleeve 36 are in sliding contact with the mounting sleeve 34 and the inner wall of the accommodating chamber 31 respectively. This arrangement makes the mounting sleeve 34 and the accommodating chamber 31 not partly frictional. Direct contact, the friction force is dispersed to the contact surface between the mounting sleeve 34 and the friction-reducing sleeve 36, and between the friction-reducing sleeve 36 and the accommodating chamber 31, thereby reducing the direct wear of the mounting sleeve 34 and the accommodating chamber 31. At the same time, the cleaning part 1 may vibrate or impact during movement, and these vibrations and impacts will aggravate the wear of the mounting sleeve 34 and the accommodating chamber 31. The existence of the friction-reducing sleeve 36 can play a certain buffering role, absorb part of the vibration and impact energy, reduce the direct collision and impact between the mounting sleeve 34 and the accommodating chamber 31, and thus reduce wear.

[0032] The cleaning blade 11 is generally made of nylon, because nylon has good insulation performance, wear resistance and certain elasticity, and can adapt to the friction with the insulator surface during the cleaning process. Figure 1 It can be seen that in order to facilitate cleaning of dust on the fixed insulator, a part of the cleaning blade 11 has extended into the cleaning area 41. In order to avoid excessive squeezing of the fixed insulator and unnecessary damage to the cleaning blade 11, in this embodiment, a limit baffle 42 that interferes with the fixed insulator is provided in the cleaning area 41. The fixed insulator thus arranged can contact the cleaning blade 11 but will not excessively squeeze the cleaning blade 11, thereby achieving the predetermined cleaning effect and protecting the cleaning blade 11.

[0033] This embodiment provides a generator closed bus internal operation device, such as Figure 5As shown, the fixed shell 4 is provided with a detection groove 61 for the detection slider 62 to slide in. The detection slider 62 is equipped with an observation module 63 of the IMX298AF model and a transmission member 64 for controlling the movement of the detection slider 62. Therefore, when in use, the detection slider 62 can be controlled to move up and down in the detection groove 61 by the transmission member 64. During the movement, the observation module 63 is used to comprehensively observe the appearance of the closed busbar or the fixed insulator of the generator to realize the relevant detection work of the generator set. At the same time, because the observation module 63 is an existing product, it will not be described in detail in this scheme.

[0034] like Figure 5 and Figure 6 As shown, a transmission screw 642 and a guide rod 643 are provided in the detection slide 61, wherein the guide rod 643 is slidably connected to the detection slider 62, and the transmission screw 642 is threadedly connected to the detection slider 62. Therefore, when the control stroke motor 641 is running, the transmission gear set 646 connected to it will drive the transmission screw 642 to rotate, so as to realize the lifting and lowering of the detection slider 62. At the same time, when the travel switches 644 arranged at both ends of the detection slide 61 contact the transmission protrusion 645 installed on the detection slider 62, the travel motor 641 will be used to control the transmission screw 642 to rotate in the opposite direction, so that the detection component 6 can comprehensively observe the internal conditions of the closed busbar of the generator.

[0035] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
