For being sprinkled water to the solar panels before being cleaned by hairbrush.The operation principle of solar panels cleaning part 1 is as follows：Work as motor
During 112 rotation, brush axle 106 is driven to rotate by shaft coupling 114, and then realize the cleaning of solar panels；Clean the micro- of angle
Adjust and mainly rely on four-bar mechanism, it contains upper frame 105, the first electric pushrod 117 and base 107, when the first electric pushrod
117 when stretching out so that the angle increase between upper frame 105 and base 107, due to base 107 and the diameter parallel of brush axle 106,
Also increase upper frame 105 and brush axle 106 forms the angle at angle；Understand like this, when the first electric pushrod 117 is retracted, top
The angle that frame 105 and brush axle 106 form angle can also reduce.When the stroke of the first electric pushrod 117 chooses suitable, angle is formed
Angular range it is smaller.When brush axle 106 is close to solar panels surface, the first electric pushrod 117 can realize fine setting.
According to present pre-ferred embodiments, with reference to Fig. 1, Fig. 3, Fig. 4 and Fig. 5, it can be seen that cleaning device is fixed and angle
The composition of coarse adjustment part 2.Wherein, the bottom of frame 206 is fixed with the second rolling bearing units 201,202, and this two rolling bearing units is main
For connection rotating shaft 111, and then realize that solar panels clean part 1 and cleaning device is fixed and the connection of angle coarse adjustment part 2；
One end hinge for being fixedly arranged in the middle of the second pusher bar support 203, the second pusher bar support 203 and the second electric pushrod 204 of frame 206
Connect, the other end of the second electric pushrod 204 is hinged on the middle part of upper connecting rod 207；The top of frame 206 and the one of upper connecting rod 207
End is be hinged, and one end of the other end and lower link 205 of upper connecting rod 207 is hinged, and the other end of lower link 205 and solar panels are clear
The middle part for washing the upper frame 105 of part 1 is hinged.
After solar panels cleaning part 1 and cleaning device are fixed and angle coarse adjustment part 2 connects, angle coarse adjustment machine is cleaned
Structure can work, and its motion is as follows：When frame 206 is fixed on fork truck, when the second electric pushrod 204 is retracted, pull on
Connecting rod 207 internally rotates, and then drives lower link 205 to pack up, so as to drive upper frame 105 to be rotated up, so as to by solar energy
Plate cleaning part 1 is moved to close to vertical position, state when this state does not work as；At solar panels cleaning part 1
When close to vertical position, when the second electric pushrod 204 stretches out, upper connecting rod 207 can be turned out, and then drive lower link 205
Expansion, so as to drive upper frame 105 to rotate down, so as to which solar panels cleaning part 1 is transferred into suitable position, for solar energy
The cleaning of plate, such as still there is small deviation micro-adjusting mechanism can be utilized to adjust.
Although the present invention is disclosed above with preferred embodiment, so it is not limited to the present invention.Skill belonging to the present invention
Has usually intellectual in art field, without departing from the spirit and scope of the present invention, when can be used for a variety of modifications and variations.Cause
This, the scope of protection of the present invention is defined by those of the claims.
