specific Embodiment approach 1
[0018] Specific implementation mode one: combine Figure 1~Figure 11 This embodiment will be described.
[0019] This embodiment provides a specific implementation of a rotary power generation cylinder used for power supply to nodes of the Internet of Things in a pneumatic system. The rotary power generation cylinder used to supply energy to the nodes of the Internet of Things in the pneumatic system is composed of a cylinder 1 and a piezoelectric power generation device 2 .
[0020] The cylinder 1 can be a double-acting cylinder (MBB50-100 double-acting cylinder of SMC Company); the center position of the rear end cover of the cylinder 1 is provided with a threaded through hole 1-1, which is used to connect with the cavity of the piezoelectric generator 2. The external thread-2-1-2 at the end of one side of the end cover 2-1 is screwed and connected to realize the fast connection between the cylinder 1 and the piezoelectric generator 2.

The invention discloses a rotary-type power generating air cylinder used for providing energy for a node of Internet of things in a pneumatic system, which is designed to solve the problems of complex structure, low energy utilization rate and loud noise of the current pneumatic piezoelectric power generating apparatus. The rotary-type power generating air cylinder comprises two parts that are an air cylinder body and a piezoelectric power generating apparatus, wherein the power generating apparatus is connected to a back end of the air cylinder through a thread pair; the piezoelectric power generating apparatus comprises a cavity body end cover, a front part cavity body component, a rotary component and a back part cavity body component; under the effect of shock of the pneumatic pressure and the fluctuation of the air pressure, a rotary shaft is driven by a rotary fan to rotate to further make a metal elastic substrate and a piezoelectric element deformed; based on the positive piezoelectric effect, electric energy is produced; and since the piezoelectric element is driven by the elastic restoring force of the metal substrate to restore, the electric energy is produced again. The rotary-type power generating air cylinder has the technology advantages that the structure is compact; mechanical energy is directly turned into electric energy and the produced energy is collected and rectified through a rectification accumulator circuit; energy is provided for the node of Internet of things; and the rotary-type power generating air cylinder has wide application prospect in the pneumatic technology field.
