Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cleaning equipment, and in particular relates to a surface cleaning device. Background Art
[0002] The generator rotor, the rotating part of the generator, rotates at high speed during normal operation, subjecting it to contamination from oil and dust. The most common contamination is caused by grease escaping from the generator during high-speed rotation, mixing with airborne dust and forming sludge on the rotor surface. This sludge increases the thermal resistance of the main insulation, making it difficult for heat generated by copper conductor losses to be dissipated through the electrical insulation and the sludge layer, leading to overheating. It can also cause discharges, creating current paths that can affect the main insulation.
[0003] Currently, the cleaning and painting of large hydro-turbine generator rotors is mostly done manually. This requires the construction of a scaffolding, where workers stand to spray cleaning agents and scrub with brushes. Manual cleaning is time-consuming and labor-intensive, with low efficiency and risks associated with cleaning on scaffolding. Utility Model Content

DETAILED DESCRIPTION
[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0023] The generator rotor is the rotating part of the generator. During normal operation, it rotates at high speeds and can be contaminated by oil or dust. The most common type of contamination is sludge on the rotor surface, which forms when grease escaping from the generator's interior during high-speed rotation mixes with dust in the air. Sludge on the rotor surface increases the thermal resistance of the main insulation, making it difficult for heat generated by copper conductor losses to be carried away through the electrical insulation and dirt layer, easily leading to overheating. It also causes discharge, forming current channels that affect the main insulation. Currently, the cleaning and painting of large hydro-turbine generator rotors is still mostly done manually. In actual rotor surface cleaning, a scaffolding must be erected, with workers standing on the scaffolding to spray cleaning agents and scrub with brushes. Manual cleaning is time-consuming and labor-intensive, with low cleaning efficiency. Furthermore, cleaning on a scaffolding carries certain risks. In view of this, the present invention provides a surface cleaning device to facilitate rotor surface cleaning and improve cleaning efficiency.
[0024] like Figure 1 and 2 As shown, the surface cleaning device includes: a mounting base 1, a cleaning mechanism 3 and a spray gun 7, the mounting base 1 is provided with a cylinder 2; the cleaning mechanism 3 includes a connecting base 4, a driving motor 5 and a roller brush 6, one side of the connecting base 4 is rotatably connected to the mounting base 1, the output end of the cylinder 2 is hinged to the connecting base 4, the driving motor 5 is installed on the connecting base 4, the roller brush 6 is rotatably connected to the side of the connecting base 4 away from the mounting base 1, and the driving motor 5 is transmission-connected to the roller brush 6; the spray gun 7 is installed at the bottom of the connecting base 4.
[0025] It should be noted that spray gun 7 is used to spray solvent. During operation, the solvent is sprayed onto the rotor surface through spray gun 7. Since the output end of cylinder 2 is hingedly connected to connecting seat 4, drive motor 5 is mounted on connecting seat 4, and roller brush 6 is rotatably connected to the side of connecting seat 4 away from mounting seat 1. Drive motor 5 and roller brush 6 are in transmission connection. Cylinder 2 drives connecting seat 4 to move up and down, and drive motor 5 drives roller brush 6 to rotate, thereby scrubbing and cleaning the rotor surface. This cleaning device is driven by cylinder 2 and drive motor 5 to achieve automatic cleaning, eliminating the need for manual cleaning and the need for additional scaffolding, greatly facilitating cleaning of the rotor surface and improving cleaning efficiency.
[0026] like Figure 1 and 2As shown, specifically, a first connecting block 8 is provided on the mounting base 1, and a second connecting block 9 is provided on the connecting base 4, and the second connecting block 9 is rotatably connected to the first connecting block 8; a rotating shaft 10 is provided on the first connecting block 8, and the second connecting block 9 is rotatably connected to the rotating shaft 10; in this way, a rotating connection between the connecting base 4 and the mounting base 1 is realized, which facilitates the cylinder 2 to drive the connecting base 4 to swing up and down, thereby improving the cleaning effect of the rotor surface.
[0027] like Figure 1 and 2 As shown, in this embodiment, a third connecting block 11 is provided at the bottom of the connecting base 4, and the spray gun 7 is mounted on the third connecting block 11. In this structure, the spray gun 7 is mounted on the third connecting block 11, and the position of the spray gun 7 mounted on the third connecting block 11 can be adjusted to adjust the relative position of the spray gun 7 and the roller brush 6, thereby facilitating the spraying of the solvent.
[0028] like Figure 1 and 2 As shown, in this embodiment, a first pulley 12 is provided at the output end of the drive motor 5, and a second pulley 13 is provided at the end of the roller brush 6. The first pulley 12 and the second pulley 13 are connected by a belt drive. In this structure, the belt is a flexible structure, which can effectively prevent the roller brush 6 from getting stuck during the cleaning process and damaging the drive motor 5.
[0029] like Figure 1 and 2 As shown, in this embodiment, the connecting base 4 is further provided with a tensioning pulley 14, which is rotatably connected to the connecting base 4. The tensioning pulley 14 is staggered with the first pulley 12 and the second pulley 13, and the belt is in transmission connection with the tensioning pulley 14. In this structure, by providing the tensioning pulley 14 and staggering the tensioning pulley 14 with the first pulley 12 and the second pulley 13, the belt is tightened when the drive motor 5 drives the roller brush 6, thereby improving transmission efficiency.
[0030] like Figure 1 As shown, in this embodiment, a cover 15 is provided on the mounting base 1. In this structure, the cover 15 is provided on the mounting base 1 to prevent oil stains from being scattered onto the cylinder 2 during cleaning, thereby preventing damage to the motor.
