Embodiment 1

[0060] A multimedia velocimeter based on triboelectric nanopower generation, comprising: the above-mentioned diversion shell 1, the diversion shell 1 is designed to be tapered, and the cross-sectional area of ​​the inlet is twice the cross-sectional area of ​​the shell 2 of the working section, The cross-sectional area of ​​the outlet of the diversion shell 1 is equal to the cross-sectional area of ​​the cavity of the working section. It can be understood that, in other trial schemes, the ratio of the cross-sectional area of ​​the inlet of the diversion shell 1 to the cross-sectional area of ​​the shell 2 of the working section can be other values, as long as the cross-sectional area of ​​the inlet of the diversion shell 1 is larger than that of the working section The cross-sectional area of ​​the housing 2 is sufficient.

Abstract

The invention provides a multi-medium velocimeter based on frictional nano-power generation, which includes: a guide shell, which is arranged at the front end of the cavity of the working section and connected with the shell of the working section. The direction of fluid flow is set; the shell of the working section has a hollow cavity structure, which is used to accommodate the TENG sensor unit and fix one end of the TENG sensor unit in its cavity through a fixed beam; the TENG sensor unit is mainly printed with the first conductive ink on the surface The first FEP film, the second FEP film with the second conductive ink printed on the surface, and the FEP cover film are bonded by PU glue in sequence, wherein the upper surface of the first FEP film and the two side surfaces of the second FEP film have microscopic a nanostructure; and an acquisition processing unit. The invention can obtain fluid velocity information with low power consumption, thereby reducing the power consumption of equipment, has the advantages of simple structure, can be directly installed in underwater submersible equipment or pipelines, has low cost, reduces environmental pollution, and the like.

Description

technical field [0001] The invention relates to the technical field of flow rate sensors, in particular to a multi-medium velocimeter based on triboelectric nano power generation technology. Background technique [0002] There are extremely rich resources in the ocean. With the depletion of land resources, many countries have invested a lot of energy in the research and development of marine resources. The exploration and development of the ocean will surely become one of the development themes of our country in the 21st century. The construction of submarine tunnels, the laying of submarine optical cables, and the construction of submarine oil pipelines are huge projects in my country in recent years. However, due to the danger and complexity of the marine environment, it is unrealistic to simply rely on manual labor to carry out extremely large and difficult marine development and survey operations. Therefore, human beings understand and develop the ocean, especially for ...
