In present work, we investigate the spectrum of several low-lying $sscq\bar{ q}$ pentaquark configurations employing the constituent quark model, within which the hyperfine interaction between quarks is taken to be mediated by Goldstone boson exchange. Our numerical results show that four $sscq\bar{ q}$ configurations with $J^{ P}=1/2^{ -}$ or $J^{ P}=3/2^{ -}$ lie at energies very close to the recently observed five $\Omega_{ c}^{ 0}$ states by LHCb collaboration, this indicates that the $sscq\bar{ q}$ pentaquark configurations may form sizable components of the observed $\Omega_{ c}^{ 0}$ resonances.
