Description

Technical Field

[0001] This utility model relates to the field of generator testing, and in particular to a cleaning mechanism and a working device for the inside of a generator enclosed busbar. Background Technology

[0002] A generator is a device that converts mechanical energy into electrical energy. It is typically equipped with fixed insulators because the stator and rotor windings of a generator are usually under high voltage. Fixed insulators effectively isolate these energized components from the casing (grounded part) and other non-energized components, preventing high-voltage arcing and short-circuit faults, and ensuring the safe operation of the generator. However, during generator operation, fixed insulators easily accumulate dust. Since dust contains various impurities, it increases the surface conductivity of the insulators, leading to a significant decrease in their insulation performance. Therefore, regular cleaning of the insulators is necessary. However, existing cleaning machines, due to their power components, are large and lack maneuverability, making them unsuitable for use in confined generator sets. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is that the existing cleaning machines are large in size and not suitable for use in narrow generator sets.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cleaning mechanism, comprising...

[0025] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this 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. The cleaning component 1 is connected to the fixed housing 4 through the mounting base 37 and mounting sleeve 34 set at both ends. Therefore, during the cleaning process, the cleaning component 1 and the cleaning blade 11 can be rotated by the drive component 2 built into the cleaning component 1 to achieve the cleaning of dust on the surface of the fixed insulator.

[0028] like Figure 2 and Figure 3 As shown, the driving component 2 is disposed in the placement cavity 35 and fixedly installed together with the top of the placement cavity 35. The output end of the driving component 2 passes through the placement cavity 35 and is equipped with a driving tenon 21. Figure 3 As shown, both connecting plate 32 and connecting plate 33 have corresponding bolt holes, facilitating the connection of connecting plate 32 and connecting plate 33 together by bolts. Furthermore, from... Figure 4 As can be seen, the center of the connecting plate 32 is provided with a drive mortise 22 that fits into the drive tenon 21.

[0029] During cleaning, the drive component 2, located in the placement cavity 35, drives the connecting plate 33 to move through the interlocking of the drive tenon 21 and the drive mortise 22. Figure 2 As can be seen, the connecting plate 2 33 is fixedly connected to the inner wall of the receiving cavity 31. Therefore, when the connecting plate 2 33 rotates, it will drive the cleaning component 1 connected to it to rotate, thereby causing the cleaning blades 11 installed on the outside of the cleaning component 1 to rotate and clean the dust on the fixed insulator. This method of installing the driving component 2 inside the cleaning component 1 makes the structure of the entire cleaning mechanism more compact, reduces the volume of each structure, makes the cleaning mechanism lighter and simpler, and facilitates operation in narrow spaces. At the same time, compared with traditional external transmission methods, such as belt drive or chain drive, the built-in driving component 2 can avoid multi-stage transmission 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 component 2 is more direct, reducing energy loss in the transmission process, improving power transmission efficiency, enabling the cleaning component 1 to work more efficiently, and increasing the cleaning effect. In addition, from Figure 1 As can be seen, a dust-collecting component 5 is provided on the fixed housing 4 at a position opposite to the cleaning area 41. Therefore, after the cleaning component 1 sweeps the dust off the fixed insulator, the dust-collecting component 5 will absorb the dust, preventing it from being adsorbed onto other parts 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 mounting sleeve 34 is connected to the fixed housing 4 at the end of the connection and has a connecting hole 38 that communicates with the placement cavity 35. The fixed housing 4 is provided with a connecting hole 39 that corresponds to the connecting hole 38. During normal use, the power cord connected to the drive component 2 can extend into the placement cavity 35 through the connecting hole 38 and the connecting hole 39 without affecting the normal rotation of the cleaning component 1, thus ensuring the cleaning work.

[0031] from Figure 2 As can be seen, the mounting sleeve 34 is disposed in the receiving cavity 31. During the cleaning process of this device, the inner wall of the receiving cavity 31 will rotate around the mounting sleeve 34, thereby causing friction with the mounting sleeve 34. To avoid wear on the outer wall of the mounting sleeve 34 and the inner wall of the receiving cavity 31, affecting their service life, in this embodiment, a friction-reducing sleeve 36 is sleeved between the mounting sleeve 34 and the inner wall of the receiving cavity 31, and the inner and outer walls of the friction-reducing sleeve 36 slide in contact with the mounting sleeve 34 and the inner wall of the receiving cavity 31, respectively. This arrangement ensures that the mounting sleeve 34 and the receiving cavity 31 do not... Direct contact disperses friction between the mounting sleeve 34 and the anti-friction sleeve 36, and between the anti-friction sleeve 36 and the receiving cavity 31, thereby reducing direct wear between the mounting sleeve 34 and the receiving cavity 31. Meanwhile, the cleaning component 1 may experience vibration or impact during its movement, which can exacerbate wear between the mounting sleeve 34 and the receiving cavity 31. The presence of the anti-friction sleeve 36 can provide a certain buffering effect, absorbing some vibration and impact energy, reducing direct collision and impact between the mounting sleeve 34 and the receiving cavity 31, and thus reducing wear.

[0032] The cleaning blades 11 are generally made of nylon because nylon has good insulation properties, wear resistance, and a certain degree of elasticity, which can withstand friction with the insulator surface during the cleaning process. Figure 1 As can be seen, in order to facilitate cleaning the dust on the fixed insulator, a part of the cleaning blade 11 has extended into the cleaning area 41. In order to avoid excessive compression of the fixed insulator and unnecessary damage to the cleaning blade 11, a limiting baffle 42 that abuts against the fixed insulator is provided in the cleaning area 41 in this embodiment. The fixed insulator with this setting can contact the cleaning blade 11, but will not excessively compress the cleaning blade 11, thereby achieving the desired cleaning effect and protecting the cleaning blade 11.

[0033] This embodiment provides a working device for the interior of a generator enclosed busbar, such as... Figure 5As shown, the fixed housing 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 model IMX298AF and a transmission component 64 for controlling the movement of the detection slider 62. Therefore, during use, the detection slider 62 can be controlled to move up and down in the detection groove 61 by the transmission component 64. During the movement, the observation module 63 is used to conduct a comprehensive observation of the appearance of the generator's enclosed busbar or fixed insulator, so as to realize the relevant testing work of the generator set. Since the observation module 63 is an existing product, it will not be described in detail in this solution.

[0034] like Figure 5 and Figure 6 As shown, the detection slide 61 is equipped with a transmission screw 642 and a guide rod 643. 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, realizing the lifting and lowering of the detection slider 62. At the same time, when the limit switches 644 set at both ends of the detection slide 61 contact the transmission protrusion 645 installed on the detection slider 62, they will control the transmission screw 642 to rotate in the opposite direction through the stroke motor 641, so that the detection component 6 can comprehensively observe the internal condition of the generator enclosed bus.

[0035] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
