Reciba un cordial saludo desde el gremio de Fisioterapia en Colombia y del grupo de trabajo Fisioterapia, COVID-19 y hospitalización. Estamos publicando información de interés sobre elementos de protección personal, fisioterapia en hospitalización, entre otras. A row of positioning holes are respectively processed on the upper distance adjusting plate (44) and the lower distance adjusting plate (47), and the supporting rod (45) is fixedly arranged between the upper distance adjusting plate (44) and the lower distance adjusting plate (47) through the positioning holes. 35) is fixed in parallel with the water flow surface, the free end of the piezoelectric cantilever beam (35) is connected with the side surface of the cylinder (43), and the cylindrical winding fluid (43) is asymmetrically arranged at the free end of the piezoelectric cantilever beam (35), namely the winding fluid is eccentric winding fluid.
Only the eccentric part of the cylinder (43) is immersed in water, so that the energy harvester with the structure does not need to consider the water insulation problem of the piezoelectric cantilever beam, the experimental condition is easy to realize, and the cylinder winding fluid of the structure is vertical to the direction of the piezoelectric cantilever beam, so that the natural frequency of the structure is higher than that of the structure, the energy harvester can generate resonance under higher excitation frequency, and the vortex-induced resonance phenomenon can be generated under a higher water flow environment than that of the structure. Compared with the surrounding fluid in other shapes, the cylindrical surrounding fluid has smaller disturbance to water flow and more obvious vortex-induced periodic shedding effect in a lower flow velocity environment, so that the good vibration energy harvesting characteristic can be ensured, and the cylindrical surrounding fluid is suitable for collecting energy in a low flow velocity environment.

The cylindrical winding fluid, the distance adjusting plate, the clamp body and the clamping device of each structure of the piezoelectric energy harvesting device are all formed by 3D printing and processing of PLA materials. The water pumping pipe (13), the water inlet pipe (6) and the water return pipe (14) are all made of organic plastics and are connected through electric melting glue.
Thus, like a sail, wind capturing device 104 can be deformed by the wind or by other means to form a shape capable of producing a force coefficient that attempts to maintain as high of a pressure in front of generator fan 102 as possible at all wind velocities. The differing pressure causes the captured wind to flow across the at least one generator fan from the front face to the rear face. In one embodiment, generator fan 102 may include at least three horizontally stacked generator fans.

4) According to the water flow vortex-induced vibration piezoelectric energy harvesting device, the positions of the piezoelectric cantilever beams can be adjusted according to the size change of the piezoelectric cantilever beams, so that the requirements of experimental design are met. Vortex-induced vibration is a physical phenomenon widely existing in nature, and is generated because when fluid flows through a blunt body surface, vortex which is alternately discharged is formed on a back flow surface of the blunt body, and because the discharge of the vortex generates uneven pressure on the surface of an object, the object is subjected to flow direction and transverse pulsating pressure. The excitation permanent magnet (30) is installed on the magnet clamp (22), a through hole is processed in the magnet clamp (22), the magnet clamp (22) is positioned on the supporting rod (21) through a jackscrew, and when the jackscrew is loosened, the magnet clamp (22) can be adjusted in an up-and-down mode, so that relevant experimental parameters can be adjusted.
