chinese patent (CN 105424092A) discloses a deep detector for ocean temperature and salt attached by marine organisms, which utilizes an ultraviolet light-emitting diode to inhibit the problems of sensor performance failure, unreliable detection data and the like caused by the attachment of the organisms. The patent also has the problems of poor heat dissipation performance, overhigh working temperature of the ultraviolet LED, reduced performance and service life and the like.
