In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations) and the spatial descriptors used herein interpreted accordingly.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be connected to the other element through intervening elements. Further, "connection" in the following embodiments is understood to mean "electrical connection", "communication connection", or the like, if there is a transfer of electrical signals or data between the connected objects.
As used herein, the singular forms "a", "an" and "the" may include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises/comprising," "includes" or "including," etc., specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Also, as used in this specification, the term "and/or" includes any and all combinations of the associated listed items.
As described in the background art, the electric power identification pile in the prior art has a problem that the electric power identification pile is not well protected from being damaged by external force due to poor warning effect caused by easy damage and fuzziness in warning or difficulty in finding out when the ambient illumination is insufficient. In addition, when mechanical operation exists around the electric power identification pile, because the electric power identification pile does not have self-protection capability and field sensing capability, electric power operation and maintenance personnel cannot obtain field information in time and take corresponding maintenance measures.
Based on the reasons, the invention provides the electric power identification device which can effectively play a warning role and prevent external force damage.
