i need pitch detection for high frequencies which is greater than 17000
Sorry, the technique used in [helmholtz~] (autocorrelation) is very precise but not for high frequencies. Certainly not 17 KHz. Pitch of acoustic instruments rarely go above 1 KHz, that's [helmholtz~] default limit but it can go to 2 KHz using message maxfreq. If you want higher, better use an fft based detector like [sigmund~] or [fiddle~].

I tried sigmund~ and set -maxfreq to 22000 and npts to 1024 but i couldn't get pitch value which are greater than 15000 hz, what is the problem.
