 本发明的最佳实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
以下结合具体实施例对本实用新型的实现进行详细的描述。
本实施例的附图中相同或相似的标号对应相同或相似的部件；在本实用新型的描述中，需要理解的是，若有术语“上”、“下”、“左”、“右”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本实用新型和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此附图中描述位置关系的用语仅用于示例性说明，不能理解为对本专利的限制，对于本领域的普通技术人员而言，可以根据具体情况理解上述术语的具体含义。
参照图1-3所示，为本实用新型提供的较佳实施例。
本实施例提供的光伏推杆的除砂除污装置，可以运用在沙漠环境，当然，其也可以运用在其他多沙或者沙尘严重的环境中，不仅限制于本实施例中的运用。
光伏推杆的除砂除污装置，包括推杆11、除尘套12以及固定支架，推杆11包括固定盖13以及内管14，固定盖13呈固定布置，内管14穿设在固定盖13上，且相对固定盖13伸缩移动；除尘套12呈环状，且套设在内管14的外周，固定支架套在除尘套12的外周，使除尘套12的内周面抵接内管14的外周面，固定支架连接在固定盖13上；当内管14相对固定盖13缩回时，除尘套12刮下内管14外周面上的沙尘和污渍。
上述的光伏推杆的除砂除污装置，内管14穿设在固定布置的固定盖13上，相对固定盖13伸缩移动，实现光伏推杆11的伸缩运动，除尘套12套在内管14的外周，内管14相对固定盖13缩回时，由于除尘套12抵接在内管14的外周面，内管14外周面上的沙尘和污渍都会被除尘套12刮下，有效避免了沙尘等杂物进入推杆11的内部，造成推杆11内部的污染甚至损坏推杆11的内部结构，保证光伏推杆11在沙漠环境中正常工作，延长了光伏推杆11在沙漠环境中的工作寿命。
具体地，固定支架包括左支架15和右支架16，左支架15以及右支架16均呈半环状，且呈对称布置，左支架15以及右支架16相互抵接套在除尘套12的外周上，半环状的左支架15和右支架16便于安装，只需要相互抵接套在除尘套12上即可。
固定支架的内周面朝内凸起形成限位条17，除尘套12的外周面部分朝内凹陷形成刮尘段18，未凹陷的部分形成台阶段19，限位条17套在刮尘段18的外周上，且抵接台阶段19的端面。
由于除尘套12抵接内管14的外周面，内管14相对固定盖13伸出的过程中，除尘套12在摩擦力的作用下会被内管14带动朝外伸出，而限位条17套在刮尘段18的外周，并抵接台阶段19的端面，对除尘套12起到有效的限制作用，避免除尘套12在内管14伸出的过程中一起朝外移动；而内管14缩回时，除尘套12抵接在固定盖13的端面，固定盖13对除尘套12的移动起到限制作用，因此除尘套12在内管14伸缩过程中都能保持相对固定。
沿背离固定盖13的方向，除尘套12的刮尘段18朝向轴心倾斜布置，整个除尘套12只有刮尘段18的端部与内管14的外周面抵接，减小除尘套12与内管14之间的接触面积，从而降低除尘套12对内管14的阻力。
刮尘段18的最小内径小于台阶段19的内径，因此台阶段19的内周与内管14的外周之间保持间隙，刮尘段18的最小内径处即刮尘段18的端部，刮尘段18的端部与内管14的外周面抵接，起到除尘的作用。
左支架15具有多个通孔20，右支架16具有多个螺纹孔21，多个通孔20与多个螺纹孔21一一对应，且通孔20与螺纹孔21呈正对布置，螺丝同时穿过通孔20以及螺纹孔21，使左支架15与右支架16锁紧。
螺丝穿过通孔20和螺纹孔21，实现左支架15与右支架16的锁紧，套在除尘套12的外周，通过这种方式实现固定支架套设在除尘套12上，安装时通过螺丝锁紧，拆卸时拧下螺丝后直接将左支架15与右支架16分离即可，简单快捷，提高装配效率。
多个通孔20呈同一竖直线布置，即多个螺纹孔21也呈同一竖直线布置，通过螺丝锁紧左支架15与右支架16时，同一竖直线布置的通孔使得固定支架更加稳固，不容易产生晃动。
左支架15具有朝向右支架16的左抵接面，左抵接面上凸起形成多个定位销22，右支架16具有朝向左支架15的右抵接面，右抵接面上凹陷形成多个定位孔23，定位孔23为盲孔，多个定位销22与多个定位孔23一一对应，且定位销22嵌入定位孔23。
左支架15与右支架16装配时，通过定位销22嵌入定位孔23，实现左支架15与右支架16的精准对位，提高安装精度，同时方便装配人员拧紧螺丝。
左支架15以及右支架16分别具有卡勾24，卡勾24扣接在固定盖13上，左支架15与右支架16通过卡勾24扣在固定盖13上，与固定盖13相对固定，内管14伸出时除尘套12通过固定支架的限制才能避免移动。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
