The utility model belongs to the technical field of water conservancy projects, and relates to an
information management device for water conservancy supervision, which comprises a management cabinet main body, a protective cover fixed at the top end of the management cabinet main body, a
water storage tank fixed at the top end of the protective cover, a
flame sensor fixed at the top end of one side of the management cabinet main body, and a plurality of fixed plates uniformly fixed at the inner side of the management cabinet main body, a fireproof
assembly is arranged on the inner side of the management cabinet body. Through the matching structural design of the pull rod and the fireproof
assembly, when a fire occurs, the pull rod detects the fire and sends a starting
signal to the fireproof
assembly, so that the fireproof assembly firstly seals the gap of the cabinet door of the management cabinet main body, and high-temperature flames or
smoke is prevented from entering the management cabinet main body; meanwhile, water stored in the
water storage tank can be injected into the inner side of the outer wall of the management cabinet body, so that the heat insulation effect is achieved, and the situation that fire spreads into the management cabinet body, and files are burnt out is effectively avoided.
