The main disadvantages of scale disease; according to this, the industry has developed a self-powered system using piezoelectric materials, that is, the power generation system that converts mechanical energy such as motion, vibration or pressure into electrical energy through the characteristics of the material. The system is typically used to charge the battery and, more importantly, to reduce the dependence and use of the battery. Among them, portable lighting equipment is currently a common type of self-powered system, mainly using manual operation such as hand or pressing, converting mechanical energy into electricity to generate electricity, or by charging the battery, such a self-powered system, Especially for the use of out-of-town carrying, it is very convenient to have a power shortage. However, the current self-powered system is still providing mechanical energy for the sake of the fact that it is more difficult to use. SUMMARY OF THE INVENTION s 3 201221765 The present invention provides a portable power generation device, which mainly includes a piezoelectric material, at least a piezoelectric material located at an inner wall of the casing, a rotating shaft pivotally connected to the inside of the casing, and a blade fixed to one end of the rotating shaft, and a rotating shaft is oppositely disposed to press the electric material located in the casing intermittently, so that the blade is subjected to an eccentric portion or another piezoelectric eccentric portion on the rotating shaft of the appropriate fluid medium, or It is at least another push, and when the rotating shaft rotates, the material is converted into the required electric energy. The piezoelectric material of the wall's mechanical energy can be shocked by the portable power generation provided by the present invention, and the overall structure is relatively simple and compact, so that it is convenient for the user to carry around, and at the same time, the blade environment can be used skillfully. The natural forces, such as the wind generated by the wind, or the hydraulic power generated by the flowing water, can be used to drive the fan blades to generate electricity, so the operation is quite simple and does not have to rely on human power. [Embodiment] First, please refer to FIG. 2 and FIG. 2, the present invention is a preferred embodiment of a strip-type power generation device, which mainly includes a casing 1 , at least one piezoelectric material 20 , and a The rotating shaft 30 and a blade 40; wherein: the casing 10 has an internal accommodating space u, and the circumferential side is provided with three screw holes 12 at equal angles, and each screw hole 12 is screwed with a adjusting screw In the inspection 13, the depth position of the end of the adjusting bolt 13 in the radial direction of the casing 1 ′ can be adjusted and formed to form a pre-pressure adjusting mechanism; the piezoelectric material 20 ′ has three sets of piezoelectric materials 2 本 in this embodiment, and 5 4 201221765 ajt ^. is fixed at the end of each adjusting bolt 13 so that the piezoelectric materials 2 〇 can be equiangularly distributed at the inner wall of the casing 10 and can be interlocked by the adjusting bolt 13 Radially adjusting the displacement, and the piezoelectric material 2〇 may be a ceramic material or a ceramic fiber composite material, etc.; the rotating shaft 30 has two free ends, and is pivotally connected to the inside of the casing 10 by a bearing 31, respectively.
