In the study of weak cosmic censorship conjectures(WCCC), some researches find that the Reissner-Nordström(RN) black hole might cloud be destroyed by a test particle with special mass and charge under some conditions, which means that the naked singularity of the black hole could be observed which is not allowed in WCCC. Meanwhile, as we never observed such naked singularities, which should not be exist in theory, we need to find an proper way to protect the black hole from being destroyed by such particles. In this paper, we studied the Reissner-Nordström black hole which is surrounded by quintessence(RN-Q) and find the black hole would be stable and safe because of the effective potential barrier induced by the quintessence term. This result may also show in a sense that the quintessence might have more potential value.
