Side walking unit includes：3rd driving wheel 405, the 3rd motor 4005, the 4th driving wheel 406 and 4 wheel driven Dynamic motor 4006.3rd driving wheel 405 and the 4th driving wheel 404 are all detachably arranged on head rod 101.First drive Dynamic motor 4001, the second motor 4002, the 3rd motor 4005 and the equal and central controller of the 4th motor 4006 2 connections, just can control the working condition of above-mentioned motor, thus controlling body in photovoltaic panel by central controller 2 Return is dynamic.

Shown in Fig. 8, it is that self-locking mechanism is arranged on the structural representation in travel mechanism.Self-locking mechanism includes being arranged on plane In walking unit：First from lock unit 501 and second from lock unit 502.First is arranged on the first driving electricity from lock unit 501 Between machine 4001 and the first driving wheel 401, for realizing the self-locking of the first driving wheel 401；Second is arranged on from lock unit 502 Between two motors 4002 and the second driving wheel 402, for realizing the self-locking of the second driving wheel 402.

First includes from lock unit 501：Worm gear and worm screw, the power output shaft of the first motor 4001 is with worm screw even Connect, worm and wheel connects, worm gear is coaxially connected with the first driving wheel 401, the first motor is controlled by central controller 2 4001 work, the power output shaft of the first motor 4001 drives worm screw to rotate, and worm screw drives worm gear wheel, and worm gear drives the One driving wheel 401 rotates；When the first motor 4001 quits work, due to worm gear can only be driven by worm screw, and can not be by Worm gear drives worm screw, so the first motor 4,001 1 quits work, the first driving wheel 401 also stops operating therewith, thus Realize the self-locking of the first driving wheel 401.

Second includes from lock unit 502：Worm gear and worm screw, the power output shaft of the second motor 4002 is with worm screw even Connect, worm and wheel connects, worm gear is coaxially connected with the second driving wheel 402, the second motor is controlled by central controller 2 4002 work, the power output shaft of the second motor 4002 drives worm screw to rotate, and worm screw drives worm gear wheel, and worm gear drives and drives Wheel rotation；When the second motor 4002 quits work, due to worm gear can only be driven by worm screw, and can not be driven by worm gear Worm screw, so the second motor 4,002 1 quits work, the second driving wheel 402 also stops operating therewith, thus realizing second The self-locking of driving wheel 402.

Self-locking mechanism also includes being arranged in the walking unit of side：3rd from lock unit 503 and four selfs lock unit 504.3rd is arranged between the 3rd motor 4005 and the 3rd driving wheel 405 from lock unit 503, is used for realizing the 3rd driving The self-locking of wheel 405；Four selfs lock unit 504 is arranged between the 4th motor 4006 and the 4th driving wheel 406, for realizing The self-locking of the 4th driving wheel 406.

3rd includes from lock unit 503：Worm gear and worm screw, the power output shaft of the 3rd motor 4005 is with worm screw even Connect, worm and wheel connects, worm gear is coaxially connected with the 3rd driving wheel 405, the 3rd motor is controlled by central controller 2 4005 work, the power output shaft of the 3rd motor 4005 drives worm screw to rotate, and worm screw drives worm gear wheel, and worm gear drives the Three driving wheels 405 rotate；When the 3rd motor 4005 quits work, due to worm gear can only be driven by worm screw, and can not be by Worm gear drives worm screw, so the 3rd motor 4,005 1 quits work, the 3rd driving wheel 405 also stops operating therewith, thus Realize the self-locking of the 3rd driving wheel 405.

Four selfs lock unit 504 includes：Worm gear and worm screw, the power output shaft of the 4th motor 4006 is with worm screw even Connect, worm and wheel connects, worm gear is coaxially connected with the 4th driving wheel 406, the 4th motor is controlled by central controller 2 4006 work, the power output shaft of the 4th motor 4006 drives worm screw to rotate, and worm screw drives worm gear wheel, and worm gear drives and drives Wheel rotation；When the 4th motor 4006 quits work, due to worm gear can only be driven by worm screw, and can not be driven by worm gear Worm screw, so the 4th motor 4,006 1 quits work, the 4th driving wheel 406 also stops operating therewith, thus realizing the 4th The self-locking of driving wheel 406.

Worm and gear in self-locking mechanism 5 can make body with constant speed drive in photovoltaic panel, thus ensureing photovoltaic panel Cleaning performance.In addition, self-locking mechanism can also make body moment stop in photovoltaic panel, thus avoiding due to inertia, make Body goes out photovoltaic panel, and when body rests in acclive photovoltaic panel, it can be avoided that body is due to Action of Gravity Field landing.

May there is the uneven situation of level due to due to installation ground in the photovoltaic panel in photovoltaic plate array, or When the power of person's body is uneven, run-off the straight when body can be caused to clean on photovoltaic plate array is even rocked, so that this Body can not steadily move, and so can reduce the cleaning performance of photovoltaic panel.Therefore body also includes straightening mechanism 6.As shown in figure 9, It is arranged on the structural representation on rack for cleaning 1 for straightening mechanism 6.Straightening mechanism 6 includes：First corrects guide wheel 601 and second rectifys Positive guide wheel 602.First rectification guide wheel 601 and the second rectification guide wheel 602 are all detachably arranged in the 3rd connecting rod.As Figure 10 Shown, for correcting the angle schematic diagram between guide wheel and driving wheel, first corrects guide wheel 601 and the 3rd driving wheel 405 presence folder Angle a, 0 ° of ＜ a≤5 °；There is angle b in the second rectification guide wheel 602 and the 4th driving wheel 406,0 ° of ＜ b≤5 °；Preferably, angle a Angle identical with the angle of angle b.Because the first rectification guide wheel 601 and the 3rd driving wheel 405 have angle a, the second rectification There is angle b in guide wheel 602 and the 4th driving wheel 406, therefore, when body not run-off the straight in photovoltaic panel, the first rectification guide wheel 601 and second correct the side not in contact with photovoltaic panel lower edge for the guide wheel 602, only when body run-off the straight in photovoltaic panel, And when angle c tilting reaches 0 ° of ＜ c≤5 °, the first rectification guide wheel 601 just can contact photovoltaic panel with the second rectification guide wheel 602 The side of lower edge, so that body steadily can move in photovoltaic panel, does not shake.
