The invention discloses a transverse piezoelectric driving deformation mirror and an assembling method thereof. A transverse shell in the deformation mirror is arranged on a base, a reflecting mirrorand a piezoelectric actuator are bonded and arranged in the inner hole of the transverse shell in a sleeved mode, and an elastic gasket is arranged on the edge of the reflecting mirror. One end face of the elastic gasket is in movable contact with the transverse shell, and the pressure applying device is in threaded sleeve with the inner hole of the transverse shell, and is in contact with the elastic gasket; and an electricity receiving assembly is arranged on the pressure applying device and is connected with the piezoelectric actuator. The method comprises the following steps of s1, bondinga piezoelectric actuator with a reflector; s2 clamping and fastening on the side surface of the reflecting mirror and the upper surface and the lower surface of the edge by using an elastic gasket clamping sleeve, and arranging on a pressure applying device; s3, fixing the pressure applying device in the transverse shell sleeve and applying pressure to an elastic gasket; s4, welding a wire and the electricity receiving assembly together, and installing the electricity receiving assembly on the pressure applying device; s5, transversely fixing the transverse shell sleeve on the base. The device has the advantages of being simple in structure, convenient to manufacture and install and capable of effectively improving the deformation of each electrode.

Smoke alarm fire extinguishing apparatus convenient to disassemble
ActiveCN109276837AImprove installation stabilityEasy to disassembleFire rescueFire alarm smoke/gas actuationDrive motorEngineering
The invention discloses a smoke alarm fire extinguishing apparatus convenient to disassemble. The smoke alarm fire extinguishing apparatus convenient to disassemble comprises a base e and a minisize smoke alarm arranged on the lower portion of the base. An alarm disassembly device is arranged on the top of the base . A liquid guide through hole is vertically formed in the base. A spraying assemblymounting barrel is vertically connected to the lower portion of the base and internally provided with a vertical screw rod. The upper end of the screw rod is connected with a lifting drive motor. A rotation drive motor is arranged at the lower end of the screw rod. An output shaft of the rotation drive motor is movably sleeved with an engagement and disengagement member. The screw rod is in threaded connection with a lifting sleeve which is horizontally connected with a spraying assembly. A storage battery and a microcontroller are arranged in the base. Compared with the prior art, the smokealarm fire extinguishing apparatus convenient to disassemble is compact in structure, a mounting seat and a fixing seat can be quickly fixedly combined or separated, and in addition, the apparatus canmake a reasonable judgment according to the location of a smoke source and intelligently adjust the location of a spray mounting seat to spray water towards the smoke source.
