Embodiment Construction
[0019] The present invention will be further described below in conjunction with drawings and embodiments.
[0020] Such as figure 1 As shown, the present invention includes an acrylic tube-rotary module 1, a spring-magnet electromagnetic induction module 2 and a friction nano power generation module 3, one end of the spring 8 of the spring-magnet electromagnetic induction module 2 and the triangular prism shape of the acrylic tube-rotary module 1 Rotation center block 5 is fixedly connected. One end of the acrylic tube 6 of the acrylic tube-rotation module 1 is fixed on the outer edge of the triangular prism-shaped rotating center block 5 through the support block 7 , and the other end is fixed to the support plate 11 of the triboelectric nano power generation module 3 . The acrylic tube-rotation module 1 is used as the structural support of the whole device. During its movement, the mechanical energy is converted from the rotation of the device into the linear reciprocating...

The invention discloses an environmental perception-oriented triboelectricity-electromagnetism composite flow velocity detection device, which comprises a spring-magnet electromagnetic induction module, a friction nanometer power generation module, an acrylic tube-rotation module and a wireless transmission power management module, one end of an acrylic tube assembly of the acrylic tube-rotating module is fixed to the outer edge of a rotating center block of the rotating module, the other end of the acrylic tube assembly of the acrylic tube-rotating module is fixed to a supporting disc of the friction nanometer power generation module, and one end of a spring of the spring-magnet electric induction module is fixedly connected with the rotating center block of the acrylic tube-rotating module, the spring-magnet electromagnetic induction module is located in the acrylic tube, so that the spring-magnet electromagnetic induction module and the friction nanometer power generation module are located in a closed space between the acrylic tube and the rotating center block. According to the invention, self power supply can be realized, rotation speed detection of driving fluid is realized by means of output characteristics of electric signals, and fluid flow velocity detection in an unmanned environment is realized based on the power supply management module in cooperation with the low-power-consumption Bluetooth module.
Description
technical field [0001] The present invention aims to solve the flow rate monitoring device of water flow / wind speed and other fluids in remote areas. It can realize the self-power supply of the flow rate monitoring device in remote areas, and realize the wireless transmission of monitoring data. More specifically, it is an environment-oriented sensing device. The triboelectric-electromagnetic composite flow velocity detection device. Background technique [0002] In the future, the demand for environmental monitoring elements such as wind speed, rainfall, and water level of unmanned weather stations will play an important role in the field of environmental monitoring. This requires daily summary of meteorological information and early warning of dangers to avoid major natural disasters. For example, heavy rainfall in a short period of time often leads to a surge in river flow, which often heralds the sudden onset of regional natural disasters. At the same time, with the rap...
