Exactly as above. A British expression. A place where an animal carcass (or carcase, depending on your dictionary), usually a horse (this is from way back when people still kept them within city limits, before automobiles took over) was disposed of and turned into glue. To be "knackered" is to compare one's self to being dead, exhausted, etc., often in a post sexual context, but any kind of tired will do. It is an allowable expression on the BBC. It has nothing to do with being injured in one's private parts, and there's many words for that, already.
