As shown in fig. 1-3, a preferred embodiment of a brush 10 includes: a drum 11, a drive cover 20, three sets of

fasteners

22, 32, 43, three sets of (headless)

bolts

25, 35, 46, a driven cover 30, a bearing 38, an actuator 40, and a retaining ring 49.

Wherein the actuator 40 includes: a hollow housing 41, two end caps 42, a fixed tube 44, a coupling 45, a straight tube 47, and a motor 50. Generally, the electric motor 50 is also called an electric motor or motor, and is composed of a stator and a rotor. The stator is electrically connected to at least one electrical wire 52 for converting electrical energy into mechanical energy for rotation of the rotor, which acts as a drive shaft 51. A set of fasteners 43 lock the motor 50 to the inside of the end cap 42, with the drive shaft 51 passing through the end cap 42 and protruding outside.

The end caps 42 engage the ends of the housing 41 by adhesive or other fastening means to enclose the motor 50 within the housing 41. The fixed tube 44 is secured at one end by another end cap 42 which is welded together. The other end of the fixed tube 44 faces the straight tube 47 and is inserted into the coupler 45 to form a channel, and the lead wire 52 extends out of the straight tube 47 through the fixed tube 44. A set of bolts 46 are locked into the coupler 45 to hold the tube 44 and tube 47 in place, respectively, to hold the tube 47 in place standing on the end cap 42. In addition, the retaining ring 49 is engaged with a groove 48 of the straight tube 47.

The outer surface 12 of the drum 11 is provided with a plurality of brush staples 13. The drum 11 is connected at both ends thereof to one of the drum inner spaces 15 inside the drum 11, respectively, allowing the actuator 40 to enter the drum inner space 15 via either end of the drum 11.

The driving cap 20 is formed with a center hole 26 along the axial direction, and the center hole 26 is protruded with a small diameter portion 23 from the outside to the inside of the driving cap 20. The small diameter portion 23 is formed with a plurality of screw holes 24 connected to a central hole 26 in a vertical (or radial) direction of the axial center of the driving cap 20.

When the driving cover 20 contacts one end surface 14 of the roller 11, the other set of fasteners 22 pass through one set of holes 21 of the driving cover 20 like screws and are locked into the roller 11, so that the driving cover 20 is fixed on the roller 11. The small diameter portion 23 enters the barrel space 15 so that the partial drive shaft 51 protrudes out of the drive cap 20 through the central hole 26. The other set of bolts 25 are locked into the screw holes 24 and press or urge the transmission shaft 51 so that the transmission shaft 51 and the driving cap 20 can rotate together.

The driven cover 30 is formed with a circular hole 36 and a bearing chamber 37 in the axial direction, the circular hole 36 is communicated with the bearing chamber 37, and the diameter of the circular hole 36 is smaller than the diameter of the bearing chamber 37. The bearing chamber 37 penetrates through the other small diameter portion 33 protruded inside the driven cover 30, and a plurality of screw holes 34 connected to the bearing chamber 37 are formed in the small diameter portion 33 in a vertical (or radial) direction of the axis of the driven cover 30. When the bearing 38 is placed in the bearing chamber 37, the other set of bolts 35 are locked into the bolt holes 34 and press or tighten the bearing 38, the circular hole 36 is not blocked by the bearing 38.

When the driven cover 30 contacts the other end surface 14 of the drum 11, the other set of fasteners 32 are screwed through a set of holes 31 of the driven cover 30, and self-lock the drum 11 to fix the driven cover 30. At this time, the small diameter portion 33 enters the cylinder space 15 together with the bearing 38, allowing the straight tube 47 to protrude outside the driven cap 30 through the bearing 38, the circular hole 36. The bearing 38 abuts against the retaining ring 49 to directly determine the length of the straight tube 47 extending out of the driven cover 30, and indirectly influence the length of the transmission shaft 51 extending out of the driving cover 20. Thus, the bearing 38 allows the straight tube 47 and the driven cover 30 to rotate relatively, and the straight tube 47 supports the actuator 40 in a suspended state in the cylindrical space 15 of the drum 11 in cooperation with the transmission shaft 51.

In brief, the driving cap 20 and the driven cap 30 enclose the actuator 40 in the drum space 15 of the drum 11. The actuator 40 is inside the brush 10, and even if the environment of the brush 10 for cleaning the solar panel encounters flowing liquid, the drum 11, the driving cover 20, the driven cover 30, the housing 41 and the end cover 42 can block the liquid from spraying or splashing on the motor 50, thereby reducing the occurrence of short circuit or electric leakage. The motor 50 is not exposed to moist water and is, of course, not susceptible to moisture or corrosion.

When electric power is not supplied, the straight pipe 47 is stationary, and the end cover 42 is prevented from rotating the housing 41 via the coupling 45 and the fixed pipe 44, so that (the stator of) the electric motor 50 remains stationary. At this point, the bearing 38 supports the driven cap 30 for rotation about the straight tube 47, causing the drum 11 to drive the drive cap 20 with the drive shaft 51 (i.e., rotor) for rotation. The drum 11 can be rotated about the actuator 40.

If the drum 11 is stationary, the driving cover 20 and the driven cover 30 are not moved, and the driving shaft 51 (i.e., the rotor) is kept stationary. At this point, the straight tube 47 rotates, which in turn rotates the fixed tube 44 and the end cap 42 via the coupling 45, causing the housing 41 and the motor 50 (i.e., stator) to rotate relative to the drive shaft 51 (i.e., rotor). Thus, the actuator 40 is in rotational relationship with the drum 11.

As shown in fig. 4, the straight tube 47 and the transmission shaft 51 at both ends of the brush 10 are disposed in a hollow frame 60. The frame 60 stands on two support portions 61 arranged side by side and connects the straight pipe 47 and the transmission shaft 51, respectively. A bearing 62 is inserted into the support portion 61 to rotatably couple the driving shaft 51 to the support portion 61. The other support portion 61 has no bearing, so the straight tube 47 is fixed to the support portion 61.

Under the power supply of the electric wire 52, the driving shaft 51 drives the driving cover 20 to rotate, so as to drive the roller 11 to rotate relative to the frame 60, and the bristles 13 clean some objects, such as the surface of a solar panel.

As shown in FIG. 5, the straight tube 47 and the transmission shaft 51 at both ends of the brush 10 are provided as shafts, and an operation unit 63 is provided. The operating unit 63 has a support portion 64, one end of the support portion 64 is bifurcated into two

arms

65, 66, the arm 65 is pivotally connected to the transmission shaft 51, and the other arm 66 is connected to the straight tube 47. The straight tube 47 is stationary, so that the electric wire 52 supplies the electric power required by the transmission shaft 51, and the roller 11 with the bristles 13 rotates relative to the support part 64, and the cleaning operation can be performed as well.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the utility model as defined in the appended claims.
