Stabilizing member 406f it is additionally provided with, in order to firm overall dither between spring element 406d and piezoelectric ceramics 406e.
Work process or the principle of high frequency clean-out assembly 406 are as follows:
After optical recognition component 405 identifies stain, top 406b abuts against target object (such as stains such as birds droppings), if the driving module 103 controlling subsystem 100 sends order-driven high frequency clean-out assembly 406 relative to described target object move toward one another, top 406b reverse extrusion spring element 406d, then there is elastic deformation in spring element 406d gradually, thus providing the pressure being gradually increased to top 406b. After there is a certain amount of elasticity in spring element 406d, if the driving module 103 controlling subsystem 100 sends order-driven high frequency clean-out assembly 406 when moving dorsad gradually relative to target object, spring element 406d recovers gradually due to elastic potential energy, thus providing the pressure being gradually reduced to top 406b. Piezoelectric ceramics 406e can sense top 406b pressure experienced size, and produces corresponding induced signal. The induced signal of the reflection pressure size from piezoelectric ceramics 406e can be fed back to control subsystem 100 by circuit board 406g. Induced signal (or claiming pressure feedback signal or pressure sensitive signal) according to the reflection pressure size from circuit board 406g, controlling subsystem 100 can be adjusted to suitable size by the pressure suffered by the 406b of top. So control subsystem 100 and can be accurately controlled top 406b removing dynamics on described target object, such that it is able to scratch photovoltaic module (photovoltaic panel) when avoiding knocking on target object. In a preferred embodiment, control subsystem 100 and can obtain top 406b cutting depths on described target object according to the induced signal of reflection pressure size and the coefficient of elasticity of spring element 406d from circuit board 406g. Piezoelectric ceramics 406e is connected with circuit board 406g, circuit board 406g is designed as annular circuit board 406g, to reduce the volume of device, realize dither system and data acquisition integration, annular circuit board 406g is fixed on the supporter 406h of this high frequency clean-out assembly 406, connecting internal piezoelectric ceramics 406e, shell 406a by the hole of side and cover whole annular circuit board 406g, outward appearance is more attractive in appearance.
Figure 12 is the electronic schematic diagram of the high frequency clean-out assembly 406 in Figure 11, detects top 406b vibration intensity on photovoltaic module by piezoelectric ceramics 406e, circuit board 406g includes amplifier 406e-1 and low pass filter 406e-2. The signal of telecommunication of the reflection pressure size that amplifier 406e-1 obtains in order to amplify piezoelectric ceramics 406e, low pass filter 406e-2 is in order to filter out the high-frequency signal setting marginal value that exceedes of the signal of amplifier 406e-1 output, and the signal after filtering is fed back to the driving module 103 controlling subsystem 100. So, control subsystem 100 and can realize the vibration of high frequency clean-out assembly 406 is knocked out the accurate control accurately controlled of pressure, and the vibration that can obtain top 406b knocks out the degree of depth.
