Description

清洁行走装置、连接桥安装方法、过坡控制组件、光伏单元及光伏阵列 技术领域
本发明基于专利号为201910533384.6,专利名称为“清洁行走装置及光伏阵列”、专利号为201910533385.0,专利名称为“清洁行走装置过坡控制组件及光伏阵列”、专利号为201910533396.9,专利名称为“连接桥安装方法、光伏单元及光伏阵列”、专利号为201910533390.1,专利名称为“用于光伏板清洁的清洁行走装置、过坡控制组件及光伏阵列”和专利号为201910533389.9,专利名称为“清洁行走装置及光伏阵列”五件中国发明专利,本发明涉及太阳能设备领域,具体是涉及一种清洁行走装置、过坡控制组件及光伏阵列。
背景技术
在现有的光伏阵列中,每一列光伏板组件中包括多个光伏板11和光伏单元1,在一列光伏板组件中,参见图1,根据光伏板11实际环境的设置情况,光伏板11倾斜设置,光伏单元1包括两个相邻的光伏板11和连接桥12,连接桥12设置在两个相邻的光伏板11之间,参见图2,连接桥12的两端分别与两个光伏板11连接,参见图3,连接桥12的两端沿连接桥12的行走面的宽度方向(图中的X 1方向)分别与光伏板11的光伏面的宽度方向(图中的Y 1方向)平行,连接桥12沿宽度方向的两端与光伏板11完全贴合,由于两个相邻的光伏板11之间有可能存在高度差及前后错位的情况,导致低光伏板、高光伏板以及以上两者之间的连接桥12形成一条存在坡度的“弯路”(参见图4),这就要求在此行走的清洁行走装置通过此路径时,清洁行走装置的行走轮必须有“转弯动作”,但是该“转弯动作”会导致清洁行走装置在行走过程中出现行走轮的行走阻力变化导致清洁行走装置的行走不平衡,从而清洁行走装置会走歪,行走轮脱轨至其中一个行走轮被卡住,无法继续行走;同时这个存在坡度的“弯路”会导致清洁行走装置的前后行走轮分别处于连接桥12的不同位置时,行走轮无法与所处的连接桥12的行走面接触,造成清洁行走装置的驱动力下降,难以实现清洁行走装置的上下坡。
清洁行走装置对光伏阵列进行清洁时,清洁行走装置在光伏板上行走,并且通过连接桥进入下一光伏板,清洁行走装置沿光伏板的宽度方向横跨在光伏板上(参见图5),图5中的X 2方向为清洁行走装置的长度方向。由于两个相邻的光伏板之间存在高度差和前后错位,使连接桥具有弯角和坡度。在清洁行走装置在行走过程中,在连接桥处需要进行爬坡,参见图6,但是现有技术中的清洁行走装置宽度方向Y 2上的行走轮之间的间距小于连接桥的坡长的长度,使得在清洁行走装置在爬坡过程中,由于整个清洁行走装置的行走轮都位于连接桥的坡面上,清洁行走装置的驱动力无法支撑整个清洁行走装置进行爬坡,导致清洁行走装置的爬升力不足,甚至在连接桥的坡度达到一定的数值时,清洁行走装置出现翻车、倾倒或仰翻的现象。
两个相邻的光伏板之间存在高度差并且存在前后错位情况,使得同时与两个光伏板连接的连接桥12上存在凸角124与凹角125(参见图7)。为提高清洁效率,使用自动清洁行走装置对光伏板进行清洁,自动清洁行走装置包括多个行走轮和毛刷,自动清洁行走装置在清洁的过程中,自动清洁行走装置2沿自动清洁行走装置2的长度方向X横跨光伏板11(参见图8),多个行走轮4分别设置在自动清洁行走装置2沿自动清洁行走装置2的长度方向的两端,而当毛刷61为直线型时,毛刷61的轴向与自动清洁行走装置2的长度方向相同。但是现在的自动清洁行走装置2中,毛刷61的安装位置大多位于沿自动清洁行走装置2的宽度方向的两个行走轮4之间(参见图9),或者是位于沿清洁行走装置2的长度方向上同一侧的两个行走轮4的侧边(参见图10);在自动清洁行走装置2行走的过程中,以上两种安装位置,容易出现毛刷61被光伏板11上与凸角124共线的边卡住,或者容易触碰到连接桥12,甚至出现毛刷61翘起的情况(参见图11),使得清洁行走装置2在连接桥12上的跨越能力有限,以及清洁效果欠佳。

发明的有益效果
有益效果
当清洁行走装置行驶至连接桥上时,机身在跨越连接桥的坡度时可发生形状的变化,便于适应光伏阵列中连接桥的形状,同时清洁行走装置中的行走轮可绕机身进行钟式摆动,便于行走轮适应连接桥的行驶面的角度,使连接桥的行驶面对行走轮进行支撑,从而使得清洁行走装置在光伏阵列中能够适应连接桥中的各种形状,避免清洁行走装置通过连接桥时出现的清洁行走装置驱动力不足的情况。
摆动件连接行走轮,摆动件上的铰接部铰接于机身,驱动摆动件上的铰接部相对机身转动,带动连接摆动件的行走轮绕机身摆动。
摆动驱动组件驱动拉杆移动,由于拉杆与第一连接杆连接,第一连接杆与摆动件连接,从而拉杆的移动带动第一连接杆的移动,第一连接杆的移动驱动摆动件上的铰接部转动。
进一步的方案是,机身包括至少两根第一横杆和至少两个第二横杆,第二横杆设置在两根第二横杆之间,第一横杆与第二横杆之间铰接连接;行走轮摆动驱动组件包括第二摆动组件,第二摆动组件包括第二连接杆,第一连接杆与第二连接杆垂直连接;相邻的第一横杆与第二横杆之间夹角变化驱动拉杆可沿第一连接杆的轴向移动;相邻的第一横杆与第二横杆之间的夹角变化驱动第二连接杆移动。
当第一横杆与第二横杆发生变化时,驱动拉杆沿第一连接杆的轴向移动,也驱动第二连接杆移动,由于第二连接杆连接第一连接杆,从而带动第一连接杆转动,从而带动连接第一连接杆的摆动件摆动。
限位块对第二连接杆的移动方向进行限位,使得在机身变形的过程中,转块能够准确转动,从而带动摆动件摆动。
在清洁行走装置未行驶至连接桥上时,控制单元可根据连接桥的行驶面与光伏板的光伏面之间的相对角度来预设转矩输出组件的驱动数值以及角度传感器的初始数值,在清洁行走装置通过连接桥的过程中,通过角度传感器检测自身角度,将自身变化的角度信息输出至控制单元,控制单元发送控制信号至转矩输出组件,使转矩输出组件驱动行走轮摆动相对应的角度,直至角度传感器检测角度恢复初始数值。
在清洁行走装置行走的过程中,挂轮设置在光伏板的侧面上,避免清洁行走装置在倾斜设置在光伏板上滑落,在行走轮发生摆动的过程中,挂轮移动组件驱动挂轮也发生摆动,使挂轮始终与光伏板的侧面有面与面上的贴合,保持清洁行走装置在行走过程中的稳固性。
挂轮与行走轮组件中的行走轮安装座固定连接,使得挂轮与行走轮之间的夹角保持不变,同时挂轮依然设置在光伏板的侧面上,避免清洁行走装置从光伏板上滑落。
摆动件的铰接部与行走轮连接,在机身变形时,可带动铰接部移动,从而带动 与铰接部铰接的行走轮的摆动。
在清洁行走装置爬坡的过程中,由于第一行走轮组与第二行走轮组之间的间距大于连接桥的坡长,使得只有第一行走轮组或者只有第二行走轮组处于连接桥的斜坡上,此时相对应的第二行走轮组或第一行走轮组处于光伏板上,将清洁行走装置部分的压力分摊至光伏板,避免整个清洁行走装置都位于连接桥的斜坡上,从而减少清洁行走装置上坡时所需要的驱动力,同时处于光伏板上的行走轮组可为处于连接桥坡面上的行走轮组提供较大的推力或拉力,同时处于坡面上的行走轮组给予位于光伏板上的行走轮组的作用力增加位于光伏板上的行走轮组与光伏板上的轨道面的贴合力,使清洁行走装置更易上坡,爬升能力更好。
当第一行走轮组与第二行走轮组之间的间距大于与连接桥连接的光伏板的宽度时,可降低清洁行走装置自身的重量对单块光伏板的压力,减少对光伏板的伤害。
在清洁行走装置爬坡的过程中,由于第一行走轮组与第二行走轮组之间的间距大于连接桥的坡长,使得只有第一行走轮组或者只有第二行走轮组处于连接桥的斜坡上,此时相对应的第二行走轮组或第一行走轮组处于光伏板上,将清洁行走装置部分的压力分摊至光伏板,避免整个清洁行走装置都位于连接桥的斜坡上,从而减少清洁行走装置上坡时所需要的驱动力,同时处于光伏板上的行走轮组可为处于连接桥坡面上的行走轮组提供较大的推力或拉力,同时处于坡面上的行走轮组给予位于光伏板上的行走轮组的作用力增加位于光伏板上的行走轮组与光伏板上的轨道面的贴合力,使清洁行走装置更易上坡,爬升能力更好。
第一连接段与第二连接段分别为连接桥与两块光伏板连接的连接部分,第一连接段与第二连接段依旧处于两块光伏板的光伏面上,清洁行走装置在光伏面上就与第一连接段或第二连接段接触,预先适应连接桥的行驶面,使清洁行走装置爬升效果更好。
连接桥的行走面的宽度方向与光伏板的光伏面的宽度方向之间存在夹角Z,并且该夹角不等于0,当以光伏板的光伏面为投影面,投影方向与投影面之间的夹 角为90度与夹角Z的差值,使得第一光伏板上的连接桥的安装位置、连接桥和第二光伏板上连接桥的安装位置位于同一直线带上,避免在第一光伏板与第二光伏板之间出现弯角的情况,从而在清洁行走装置上下坡的过程中,清洁行走装置能够更好地保持自身平衡进行爬坡,使清洁行走装置更易于上下坡。
连接桥通过第一连接段与第一光伏板连接,连接桥通过第二连接段与第二光伏板连接,以上两段连接段分别设置在两块光伏板上,使清洁行走装置在光伏板上提前进入连接桥上,快速适应翘起的连接桥。
连接桥的行走面的宽度方向与光伏板的光伏面的宽度方向之间存在夹角Z,并且该夹角不等于0,当以光伏板的光伏面为投影面,投影方向与投影面之间的夹角为90度与夹角Z 1的差值,使得第一光伏板上的连接桥的安装位置、连接桥和第二光伏板上连接桥的安装位置位于同一直线带上,避免在第一光伏板与第二光伏板之间出现弯角的情况;并且清洁行走装置的机身可变形,当清洁行走装置行驶至连接桥上时,机身的可变形使机身适应光伏阵列中连接桥的形状,同时清洁行走装置中的行走轮可绕机身进行钟式摆动,便于行走轮适应连接桥的行驶面的角度,使连接桥的行驶面对行走轮进行支撑,从而使得清洁行走装置在光伏阵列中能够适应连接桥中的各种形状,避免清洁行走装置需要通过连接桥时而出现的清洁行走装置所需驱动力不足的情况。
由于毛刷组件设置在连接杆组件中的第一连接杆上,第一行走轮与第二行走轮分别设置在机身的长度方向的两端上,而第一连接杆分别与第一行走轮、第二行走轮连接,第一连接杆设置在第一行走轮与第二行走轮之间,使得第一连接杆的移动与第一行走轮的移动、第二行走轮的移动同时同步,设置在第一连接杆上的毛刷组件的移动也实现与第一行走轮的移动、第二行走轮的移动同时同步,在清洁行走装置在爬桥过程中,由于第一连接杆设置在第一行走轮与第二行走轮之间,使得第一连接杆与光伏板之间保持固定距离,在行走轮通过连接桥上时,第一连接杆不会与光伏板的边产生接触,同理,安装在第一连接杆上的毛刷也不会发生翘起的情况,从而避免由于毛刷安装位不当导致清洁行走装置跨越能力与清洁能力有限的情况,而第一连接杆的两端分别通过具有拐点的连接件与第一行走轮、第二行走轮连接,使得行走轮与第一连接杆之间活连接 ,使得行走轮的转动与毛刷组件的转动之间互不干扰、互不影响。
当第一连接杆设置有第一行走轮组与第二行走轮组之间时,毛刷组件的移动位置也与第一行走轮组、第二行走轮组的移动位置同时同步,也能够避免毛刷触碰到光伏板的边。
第一连接杆与第一行走轮的转动轴心、第二行走轮的转动轴心共线设置,使得第一连接杆上的毛刷组件的移动与第一行走轮的移动、第二行走轮的移动之间的同步程度更好。
拐点设置在行走轮的空心部内,并且行走轮的中心线经过拐点,使第一连接杆的长度适用于清洁行走装置在行走过程中可能产生的变形。
拐点设置有第一行走轮、第二行走轮外,并且第一连接杆可伸缩,便于第一连接杆的长度适用于清洁行走装置在行走过程中可能产生的变形。
驱动毛刷组件转动的双向电机设置在第一连接杆与第二连接杆之间,也使双向电机设置在第一行走轮与第二行走轮之间,更合理使用清洁行走装置的安装空间。
行走轮驱动装置与第一行走轮同时设置在固定组件上,使部件安装更加紧凑,环抱紧固组件上的中空部用于与第一行走轮上的凸起块配合连接,使第一行走轮与环抱紧固组件之间的连接更稳固。
环抱紧固组件在第一侧板的下方,电极设置有第二侧板上,使得行走轮安装座上的安装位置更加合理。
轴承可作为转速分离器,第一连接杆通过轴承分别与第一行走轮、第二行走轮连接,使得第一连接杆的工作状态与行走轮的工作状态可互不干扰。

参见图12,光伏单元1包括第一光伏板11、第二光伏板13以及连接桥12,在本实施例中,第一光伏板11与第二光伏板13分别倾斜设置,并且倾斜的角度相同,第一光伏板11与第二光伏板13沿第一光伏板11的长度方向Y 3并排设置。连接桥12设置在第一光伏板11与第二光伏板13之间,在本实施例中,连接桥12的安装方式为:连接桥12的第一连接端与第二连接端一一对应分别与第一光伏板11、第二光伏板13连接。参见图13,连接桥12的行走面的宽度方向X 1与第一光伏板11的光伏面的宽度方向Y 1之间设置有夹角Z 1,同样地,连接桥12的行走面的宽度方向与第二光伏板13的光伏面的宽度方向之间设置有夹角Z 2,夹角Z 1等于夹角Z 2,夹角Z 1与夹角Z 2均不等于0。作为另一实施方式,连接桥12与光伏板之 间的连接处可存在间隙,该间隙须满足清洁行走装置能够从光伏板过渡至连接桥12,或者从连接桥12过渡至光伏板。

作为另一实施方式,位于光伏板的最高点的挂轮71与行走轮组件4固定连接,行走轮组件4中的行走轮安装座43与挂轮71固定连接,在本实施方式中,连接挂轮71的连接杆711垂直于行走轮41的转动中心线。当清洁行走装置2中的挂轮71与行走轮组件4固定连接时,挂轮71与行走轮41之间的夹角保持不变,即挂轮71与行走轮41之间的相对位置不变,此时需将连接有连接桥12的光伏板的位置下移,但是连接桥12的位置不变,从而连接桥与光伏板的相对位置变化,使得在 行走轮41在摆动的过程中,带动挂轮71摆动时,光伏板下移调整后为摆动的挂轮71腾出空间,防止桥接处的光伏板的侧面阻挡挂轮71的摆动。
在本实施例中,四个行走轮41中包括有第一行走轮46与第二行走轮47,第一行走轮46与第二行走轮47分别设置在机身3沿机身3的长度方向的两端,第一行走轮46与第二行走轮47设置在机身3沿机身3的宽度方向的同侧。

作为另一实施方式,第一连接杆63沿第一连接杆63轴向的两端分别通过连接件65与第一行走轮46、第二行走轮47连接,第一连接杆63可位于第一行走轮46与第二行走轮47之间,此时,清洁驱动装置62不再是双向电机,可用单向电机驱动第一连接杆63的转动,从而带动第一连接杆63上的毛刷组件转动。
由于毛刷组件61设置在连接杆组件中的第一连接杆63与第二连接杆64上,第一行走轮46与第二行走轮47分别设置在机身3沿机身3的长度方向的两端上,而第一连接杆63、第二连接杆64分别与第一行走轮46、第二行走轮47连接,第一连 接杆63设置在第一行走轮46与第二行走轮47之间,使得第一连接杆63、第二连接杆64的移动与第一行走轮46、第二行走轮47的移动同时同步,设置在第一连接杆63、第二连接杆64上的毛刷组件61的移动也实现与第一行走轮46、第二行走轮47的移动同时同步,在清洁行走装置2在爬桥过程中,由于第一连接杆63设置在第一行走轮46与第二行走轮47之间,使得第一连接杆63与光伏板之间保持固定距离,在行走轮通过连接桥12上时,第一连接杆63不会与光伏板的边产生接触,同理,安装在第一连接杆63上的毛刷也不会发生翘起的情况,从而避免由于毛刷安装不当导致清洁行走装置2跨越能力与清洁能力有限的情况,而第一连接杆63的两端分别通过具有拐点66的连接件65与第一行走轮46、第二行走轮47连接,使得行走轮与第一连接杆63之间活连接,使得行走轮的转动与毛刷组件的转动之间互不干扰、互不影响。
在本实施例中,参见图18,机身3朝向双向电机62的一侧设置有转轴固定组件10,转轴固定组件10包括转轴固定件101、第一转轴102、第二转轴103和转轴连杆104,转轴固定件101连接机身3,第一转轴102设置在转轴固定件101上,第二转轴103设置在双向电机62上,转轴连杆104的两端分别与第一转轴102、第二转轴103铰接,转轴连杆104位于第一转轴102与第二转轴103之间。
在本实施例中,第一连接杆63、第二转轴103、第一行走轮46的转动轴心、第二行走轮47的转动轴心共线设置,使得第一连接杆63上的毛刷组件61的移动与第一行走轮46的移动、第二行走轮47的移动之间的同步程度更好。同样地,由于第二连接杆64与第一连接杆63沿第一连接杆63的轴向共线设置,第二连接杆64、第二转轴103和第一行走轮41的转动轴心、第二行走轮41的转动轴心共线设置。同时,位于机身2的沿机身2的长度方向的两个行走轮所相对应的两个铰接部441与第一转轴102共线设置;行走轮内的拐点66与该行走轮对应的铰接部441共线设置,使得机身的变形程度更好。

作为另一实施方式,第一行走轮46的中心线、第二行走轮47的中心线不经过与其对应的两个万向接头65的拐点66,此时第一连接杆63与第二连接杆64均可伸缩,便于第一连接杆63的长度适用于清洁行走装置2在行走过程中可能产生的变形。
在本实施例中,固定组件还包括环抱紧固组件68,行走轮安装座43包括第一侧板431与第二侧板432,第一侧板431与第二侧板432垂直连接,第一侧板431水平放置,环抱紧固组件68设置在第一侧板431的下方,环抱紧固组件68安装在第一侧板431远离机身3的一侧上。行走轮上设置有朝向固定组件的一侧设置有凸起块411,该凸起块411为轮毂延伸凸起块,环抱紧固组件68包括第一环抱件681和第二环抱件682,第一环抱件681与第二环抱件682之间设置有第一中空部683,轮毂延伸凸起块411通过轴承69连接在第一中空部683内。第二侧板432上设置有第二中空部433,行走轮驱动装置42的驱动杆依次穿过第二中空部433、第一中空部683与行走轮41连接,行走轮驱动装置42设置在行走轮安装座43上。同理地,清洁行走装置2中另一组清洁组件6的设置方式如上述。

为了使清洁行走装置2更好地进行爬坡,在本实施例中,在清洁行走装置上2设置有第一行走轮组和第二行走轮组,其中第一行走轮组包括第一行走轮46和第二行走轮,第二行走轮组包括第三行走轮48和第四行走轮,其中第一行走轮与第二行走轮沿机身3的长度方向X 2设置,第三行走轮48和第四行走轮也沿机身3的长度方向X 2设置。参见图27,在本实施例中,第一行走轮46和第三行走轮47分别沿机身3的宽度方向Y 2设置,第一行走轮46与第三行走轮410设置在机身3沿机身3的宽度方向的同侧,第一行走轮46与第三行走轮410之间的间距大于连接桥的坡长。第一行走轮46与第三行走轮410之间的间距可为300mm~3000mm,其中第一行走轮46与第三行走轮410之间的最优间距可为1000mm~2100mm。在清洁行走装置2爬坡的过程中,由于第一行走轮46与第三行走轮410之间的间距大于连接桥12的坡长122,使得在机身3的第一行走轮组或者第二行走轮组两者其一处于连接桥12的斜坡上,此时第二行走轮组或第一行走轮组处于光伏板上,将清洁行走装置2部分的压力分摊至光伏板,避免整个清洁行走装置2都位于连接桥12的斜坡上,从而减少清洁行走装置2上坡的所需驱动力,同时处于光伏板上的行走轮组可为处于连接桥12坡面上的行走轮组提供较大的推力或拉力,同时处于坡面上的行走轮组给予位于光伏板上的行走轮组的作用力增加位于光伏板上的行走轮组与光伏板上的轨道面的贴合力,使清洁行走装置2更易上坡, 爬升能力更好。作为另一实施方式,清洁行走装置2包括第一行走轮组48和第二行走轮组49,参见图28,第一行走轮组48与第二行走轮组49设置在机身3沿机身3的长度方向的同一侧上,第一行走轮组48包括第一行走轮481与第二行走轮482,第二行走轮49组包括第三行走轮491与第四行走轮492,第二行走轮482与第三行走轮491相邻设置,第二行走轮482与第三行走轮491之间的间距大于连接桥12的坡长。此时机身3可与第一行走轮组48、第二行走轮组49铰接。第一行走轮482与第三行走轮491之间的间距可为300mm~3000mm,其中第一行走轮482与第三行走轮491之间的最优间距可为1000mm~2100mm。
在本实施例中,连接桥12设置在两块光伏板之间,第一行走轮组与第二行走轮组之间的间距大于与连接桥12相邻的单块光伏板的宽度,可降低清洁行走装置自身的重量对单块光伏板的压力,减少对光伏板的伤害。
当清洁行走装置2行驶至光伏板11上第一连接段121时,通过第一摆动组件8驱动行走轮41进行摆动,直至行走轮41的行走面与连接桥12的行驶面贴合时,行走轮41停止摆动。
参见图29,当清洁行走装置2靠近桥接段122的前侧轮走上桥接段122时,清洁行走装置2由“矩形”变化成“平行四边形”。由于第一摆动组件8连接第一横杆31,在机身3变形的过程中,相邻的第一横杆31与第二横杆32之间角度变化驱动套筒87沿第一连接杆63的轴向移动,同时推动与第一连接杆63垂直固定连接的第二连接杆64的移动,第二连接杆64的移动带动第一连接杆63的移动,从而带动与第一连接杆63连接的摆动件44的移动,从而实现行走轮41向清洁行走装置2的内侧摆动,直至相邻的第一横杆31与第二横杆32之间夹角不再变化时停止摆动。
当清洁行走装置2的后侧轮走上桥接段122时,清洁行走装置2由“平行四边形”变化成“矩形”。相邻的第一横杆31与第二横杆32之间夹角的变化再次驱动行走轮41朝向清洁行走装置2的外侧摆动,直至清洁行走装置2的后侧轮离开桥接段122,且走上第二连接段123时,机身3变回“矩形”时停止摆动。
清洁行走装置2在离开第二连接段123前,由第一摆动组件8驱动行走轮41摆动,直至行走轮41的行驶面与光伏板11上的行走轨道贴合,完成清洁行走装置2上桥及下桥的全过程。
连接桥12的行走面的宽度方向与光伏板的光伏面的宽度方向之间存在夹角Z,并且该夹角不等于0,当以光伏板的光伏面为投影面,并且以投影方向进行投影时,第一光伏板11上的连接桥12的安装位置、连接桥12和第二光伏板13上连接桥12的安装位置位于同一直线上,避免在第一光伏板11与第二光伏板13之间出现弯角的情况,从而避免清洁行走装置2进行转弯;并且清洁行走装置2的机身3的第一横杆31与第二横杆32之间铰接连接,当清洁行走装置2行驶至连接桥12上时,相邻的第一横杆31与第二横杆32之间的夹角可变化,使机身3适应光伏阵列中连接桥12的各种形状,同时清洁行走装置2中的行走轮41可绕机身进行钟式摆动,便于行走轮41适应连接桥12的行驶面的角度,使连接桥12的行驶面对行走轮41进行支撑,从而使得清洁行走装置2在光伏阵列中能够适应连接桥12中的各种形状,避免清洁行走装置2需要通过连接桥12时而出现的清洁行走装置2的所需驱动力不足的情况。
最后需要强调的是,本发明不限于上述实施方式,如连接桥、毛刷的结构与形状的改变等变化也应该包括在本发明权利要求的保护范围内。
工业应用性
本发明用于光伏设备应用场合,本发明的清洁行走装置通过可进行钟式摆动的行走轮适应光伏阵列中连接桥不同的形状,清洁行走装置上的第一行走轮组和第二行走轮组沿机身的长度方向设置,第一行走轮组和第二行走轮组之间的间距大于连接桥的坡长,避免清洁行走装置在通过连接桥时出现驱动力不足的情况;连接桥的行走面的宽度方向与光伏板的光伏面之间存在夹角,该夹角不等于0,使清洁行走装置在连接桥上能够更好地保持自身平衡进行爬坡;清洁行走装置上安装在第一行走轮和第二行走轮之间的毛刷组件与光伏板保持固定距离,在清洁行走装置爬坡时,毛刷组件中的第一连接杆不会与光伏板的边发生接触的同时,第一连接杆上的毛刷不会翘起,避免毛刷组件清洁不到位的情况。
