The invention discloses a fireproof structure of a building curtain wall, relates to the technical field of building engineering and building fire prevention, and solves the problems that an existing glass curtain wall is easy to break after being heated and cannot play a good fire insulation role, dust is easy to enter a water curtain nozzle after the water curtain nozzle is exposed outside for a long time, head collision and blockage are caused, and the service life of the water curtain nozzle is influenced due to collision. Comprising a curtain wall mounting piece; a group of glass curtain walls are arranged in front of and behind the inner side of the curtain wall mounting piece; the upper part of the curtain wall mounting piece is connected with a group of spray head cover plates through a hinge; and a group of pipeline sliding pieces are connected into the water curtain water supply pipeline in a sliding manner. The strength of the glass curtain wall can be improved, when the glass curtain wall is heated and broken, certain integrity is still kept, the spray head can be well protected, meanwhile, the spray head cover plate can be opened in time, an alarm signal is sent, the spray head cover plate can be automatically opened in a linkage mode when a water curtain system works, the structure is simple, and the practicability is high. And the use stability is higher.

The invention discloses a temperature measurement method of an internal quenching type rare earth luminescence lifetime temperature probe based on the change of fluorescence lifetime to realize temperature detection. The center of the present invention is doped with rare earth trivalent ions Yb 3+ and B 3+ The nano-core, surrounded by an inert shell, where Yb 3+ and B 3+ There is a phonon-assisted energy transfer process between rare earth ions. Because phonons participate in the energy transfer process, the lifetime of rare earth ions changes with temperature changes. The inert shell can protect the lifetime of the luminescent core from changing with the environment (except temperature) And the role of the change occurs, the luminescence band is in the 700-1700nm region, and the water solubility can be improved by modifying the ligand on the surface. The luminescence lifetime temperature probe of the present invention is a near-infrared luminescence lifetime temperature probe that can accurately measure temperature in different complex environments (including living bodies), and has internal quenching temperature sensitivity, near-infrared band luminescence, nanometer size level, accurate and quantifiable, Good stability and dispersion.
