Bridge supporting damping support for constructional engineering
ActiveCN113605221AImpact of shock absorptionGuaranteed stabilityClimate change adaptationBridge structural detailsTemperature controlClassical mechanics
The invention relates to the technical field of constructional engineering, in particular to a bridge supporting damping support for constructional engineering. The bridge supporting damping support comprises a frame assembly and a damping assembly and a waterproof assembly which are arranged on the frame assembly; the frame assembly comprises a top plate, a bottom plate, a base and a limiting rod; the bottom plate is detachably fixed to the top of the base, and a set of circular grooves symmetrically penetrate through the plate face of the edge of the bottom plate; the top of the base is provided with a set of sliding grooves which correspond to and are matched with the circular grooves in a one-to-one mode; a set of limiting rods perpendicular to the bottom plate face of the top plate are symmetrically fixed to the bottom plate face of the top plate; rod bodies of the limiting rods penetrate through the corresponding circular grooves and are connected into the corresponding sliding grooves in a sliding mode; the damping assembly comprises a damper, a spring, a temperature control valve, an electromagnet and a one-way valve; and the waterproof assembly wraps the frame assembly in a sealed mode. The problems of poor damping effect, poor safety and the like in the prior art can be effectively solved.

Hollow anode ion source used for ultra high vacuum system
InactiveCN101661861BGuaranteed electrical insulationStable deliveryVacuum evaporation coatingSputtering coatingUltra-high vacuumIon beam
The invention discloses a hollow anode ion source used for an ultra high vacuum system. The lower part of a cathode (8) of the hollow anode ion source is provided with a water channel (10), and the upper part is provided with an ionization chamber (28) the outside of which is sheathed with an insulation sleeve and a metal sleeve; the lower port of the water channel (10) is provided with a cover board (11) on which an inflow pipe (20) and an outflow tube (21) are through welded; the outflow tube (21) is in insulation sealed connection with a flange (13) through a water pipe insulation sleeve (23) and a water pipe seal ring (25); the bottom of the ionization chamber (28) is communicated with an ionization chamber intake pipe (18) the lower end of which is arranged in a gas pipe hole (19); the intake pipe (18) is welded on the bottom of the gas pipe hole (19); a seal ring (14) is arranged between the insulation sleeve and the flange (13); and the upper end of the metal sleeve is fixedly connected with an anode (3), and the lower end is in butting connection with the flange (13). The hollow anode ion source generates low-energy ion beam current the energy of which is lower than 30eV under ultra high vacuum.
