The invention provides a pantograph with a self-protection device. The pantograph comprises a first mounting box, a protection plate driving mechanism is arranged in the first mounting box, the outputend of the protection plate driving mechanism is connected with a protection plate, a second mounting box is arranged on one side of the first mounting box, and a pantograph assembly is arranged on the second mounting box. A protection box is fixedly mounted at the top of the second mounting box, the protection plate is used for protecting the pantograph assembly when the pantograph is used, andthe protection box is used for protecting the pantograph assembly when the pantograph is not used. By designing the protection device, the wind resistance of the pantograph can be reduced in the usingprocess, the pantograph is prevented from being damaged due to collision in the using process, storage protection can be conducted when the pantograph is not used, and the service life of the pantograph is prolonged.

    本发明提供一种具有自保护装置的受电弓,包括第一安装箱,所述第一安装箱内设有防护板驱动机构,所述防护板驱动机构的输出端与防护板连接,所述第一安装箱的一侧设有第二安装箱,所述第二安装箱上设有受电弓组件,所述第二安装箱的顶部固定安装有防护箱,所述防护板用于受电弓使用时对受电弓组件进行防护,所述防护箱用于对受电弓未进行使用时的受电弓组件进行防护。本发明通过设计防护装置,既可以使受电弓在使用过程中减少风阻,防止受电弓使用过程中因为撞击损坏,又能在不使用受电弓时,进行收纳防护,延长了受电弓的使用寿命。
