The utility model provides a kind of safety protection steam generator, comprising: boiler shell, with inner cavity, and with inner cavity communication inlet liquid pipeline, exhaust pipeline;Heating assembly, be set on the outer wall of the bottom plate of boiler shell, for heating bottom plate, and heat is transferred to the liquid flowing into inner cavity by bottom plate, to generate steam;Temperature controller, be set in the outer wall center area of bottom plate, for detecting the temperature of bottom plate, and according to the temperature of bottom plate control heating assembly's operating state;Solenoid valve, be set in exhaust pipeline;Pressure relief valve, be set on boiler shell, and with inner cavity communication;The utility model reduces the structural complexity degree of boiler shell and steam generator on the one hand, is favorable to reduce production manufacturing difficulty, on the other hand, because corresponding assembly hole is saved, it is unnecessary to additionally consider corresponding sealing problem, also improve the safety protection performance of steam generator.

The utility model relates to the technical field of human body safety protection devices, in particular to a telescopic helmet which comprises a spherical crown-shaped top shell, at least one annular bottom shell and a telescopic structure. The outer diameter of the top shell is smaller than the inner diameter of the bottom shell, and the telescopic structure comprises a buckle and a sliding strip matched with the buckle; when the buckle loosens the sliding strip, the sliding strip can slide back and forth along the buckle so as to drive the top shell to retract into or extend out of the bottom shell; and when the sliding strip is clamped by the buckle, the sliding strip cannot slide. Therefore, the telescopic helmet is internally provided with the telescopic structure for connecting the top shell and the bottom shell, and by utilizing the telescopic mechanism of the telescopic structure, the helmet can be ensured to be fully stretched into a complete protection form during use, so that the safety protection performance is ensured; when the helmet is not used, the size is reduced, and the helmet is in an overlapped compact state, so that the carrying portability and the storage convenience of the whole structure are greatly improved, and the diversified requirements of modern users on the helmet are met.

This utility model belongs to the technical field of work platforms, specifically relating to a safe work platform for building construction. It includes a base, a lifting support mechanism above the base, and a safety protection mechanism above the lifting support mechanism. Through the safety protection mechanism, an electric telescopic rod is activated to lift and lower a movable receiving plate. Depending on the on-site work conditions, the movable receiving plate is adjusted and extended via the electric telescopic rod, thus providing good protection for tools used by workers or waste materials generated during construction. Simultaneously, the movable receiving plate allows waste materials to fall into a waste box. A climbing frame allows workers to climb onto the platform, and safety railings and a rotating gate protect the workers. Load-bearing bars and supporting diagonal braces provide support and protection for the platform, railings, rotating gate, and construction personnel, ensuring effective safety protection for personnel walking on the construction safety work platform. It is highly practical.
