A locking 30 amp plug is 220 not 110.
While I agree a pic would help our second statement is wrong. Locking plugs come in lots and lots of configurations from 120v up to 480v. To suggest that none exist in a particular voltage is silly.
I would guess, by the wattage of your gen., that is has a 30A, 120v locking outlet. It could have a 20A 120v locking outlet. These would be different configurations. It could also possibly have a non-standard size. While these are available they are rather difficult to find. The best bet is to take a picture, the actual gen, or the model number off the outlet to a professional electrical supply house. They should be able to get you the right thing.
