Novel hydrological hanging box

The utility model discloses a novel hydrological hanging box, which comprises an outer frame and a measuring rod, two groups of door opening and closing mechanisms matched with each other are mounted at the outer frame, each door opening and closing mechanism comprises two groups of first door plates and second door plates, and each first door plate and each second door plate which are adjacent are hinged through a hinge. The two second door plates are hinged through fixing pieces, the two first door plates are hinged to the outer frame through pin shafts, the back face of the outer frame is fixedly connected with a positioning mechanism, and the positioning mechanism comprises a limiting box; the hexagonal and six sling seats are used, better stability is achieved, the shaking amplitude in a strong wind environment is reduced, the door opening and closing mechanism which is opened in an upward rotating mode can effectively prevent accidental opening of the protection door and personnel falling phenomena caus
