[0026] Example

[0027] like Figure 1-4As shown, the present invention provides an amphibious environmental energy collection piezoelectric device, including a shell 11, a fixed part and a force-bearing part, both of which are arranged on the shell 11, the fixed part includes a main shaft module and a branch-type lever 2, the main shaft module passes through the upper and lower sides of the shell 11, the branch-type lever 2 is sleeved on the main shaft module, the force-bearing part includes a piezoelectric module and a power-assisting module, the piezoelectric module is surrounded and arranged inside the shell 11, and the power-assisting module is arranged on both sides of the outer surface of the shell 11.

[0028] The spindle module includes a spindle 1, which passes through the upper and lower sides of the housing 11. The connection between the spindle 1 and the housing 11 is provided with a slide rail device 3, a limit device 4 and a waterproof piston 5. The slide rail device 3 and the limit device 4 are both rotatable structures, and the slide rail device 3 slides up and down on a vertical plane.

[0029] The tree-branch type lever 2 includes a main rod 21, one side of which is connected to a vertical rod 22, and the other side of the main rod 21 is hinged to the tail end of the oblique rod 23 through a hinge support 26, and a tension spring 25 is also arranged between the outer surface of the oblique rod 23 and the outer surface of the main rod 21, and a limit rod 24 connected to the main rod 21 is arranged below the tension spring 25.

[0030] The piezoelectric module includes a sheet piezoelectric material 6 and an annular piezoelectric power generation device 7 . The sheet piezoelectric material 6 is arranged at both upper and lower ends of the housing 11 . The annular piezoelectric power generation device 7 is arranged around the housing 11 .

[0031] The annular piezoelectric power generation device 7 includes a substrate 71 . The substrate 71 is located between two flexible piezoelectric materials 73 , and a slide rail 72 is provided on a portion of the substrate 71 located outside the flexible piezoelectric material 63 .

[0032] The booster module includes a pressure block 9, a float 10 and a gear-type booster sheet 8. The pressure block 9 is located on both sides of the upper surface of the shell 11, the float 10 is located on both sides of the lower surface of the shell 11, and the gear-type booster sheet 8 is located on both sides of the outer surface of the shell 11. Both the pressure block 9 and the float 10 are detachable structures.

[0033] Working principle: the force-bearing part is connected to the main shaft 1 through a rotatable slide rail device 3, and the maximum displacement is limited by a limit device 4; the waterproof piston 5 is fixed on the upper end of the limit device 4. When the force-bearing part of this housing 11 fluctuates up and down, the vertical rod 22 of the tree-branch lever 2 can squeeze the annular piezoelectric generator 7 to generate current; when the force-bearing part rotates, the main rod 21 of the tree-branch lever 2 can drive the oblique rod 23 to continuously knock the block-type piezoelectric material 6 to generate current; when the force-bearing part stably squeezes the annular piezoelectric generator 7 and rotates under the action of the pressure block or the buoyancy block, the vertical rod 22 continuously slides on the slide rail 72 of the annular piezoelectric generator 7 to squeeze the substrate 71 of the annular piezoelectric generator 7 to generate current, and the three power generation methods can be combined with each other.

[0034] Piezoelectric materials have piezoelectric effect, which can be divided into positive piezoelectric effect and inverse piezoelectric effect according to different coupling principles. The principle of positive piezoelectric effect is that when mechanical force is applied to piezoelectric material in a certain direction, the piezoelectric material will deform, causing the center of gravity of positive and negative charges inside the material to not coincide, thus causing the surface of the material to be charged. This phenomenon of polarizing piezoelectric materials and forming crystal surface charges due to mechanical force is called positive piezoelectric effect. Figure 5 As shown. In contrast to the above situation, when a piezoelectric material with piezoelectric effect is placed in an electric field, the electric field will cause the displacement of the positive and negative charge centers inside the crystal material. This polarization displacement will cause the material to deform. This phenomenon of "electricity" generating "mechanical deformation" is called the inverse piezoelectric effect. Figure 6 shown.

[0035] Therefore, the present invention adopts the above-mentioned amphibious environmental energy collection piezoelectric device, which can generate electricity by causing the piezoelectric unit to produce a piezoelectric effect through the rotation and up and down movement of the force-bearing part under the action of wind, waves, and water scouring, thereby greatly improving the utilization rate of the piezoelectric unit and having a great significance for the research on the collection and application of renewable energy.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
