log4net has a concept called logger hierarchy.

A logger is said to be an ancestor of another logger if its name followed by a dot is a prefix of the descendant logger name.

The hierarchy works very much in the same way as the namespace and class hierarchy in .NET. This is very convenient as we shall soon see.

So you really should be creating your instance specific loggers with . characters instead of _ characters.

_log = LogManager.GetLogger("DataCollectionClass." + deviceName + "." + DateTime.Now.ToString("MMddyyyy"), typeof(SomeClassTypeHere));

Then in the configuration file reference the logger hierarchy like the following.

Notice how the logger name reference does not contain the fully qualified name used in code. It only references the root of the name. Think of it in the same way you think of namespaces.
