Triboelectric float flow sensing device and flow detection equipment

Abstract

The invention discloses a triboelectric type float flow sensing device and flow detection equipment. The triboelectric type float flow sensing device comprises a machine body, which is internally provided with an accommodating space, a first end of the machine body in the first direction is provided with a fluid inlet, and a second end is provided with a fluid outlet; a floater structure, which isarranged in the accommodating space and can move along the first direction and keep balance at a certain position when fluid flows through the accommodating space; the side wall of the accommodatingspace is provided with a first friction power generation pair; the side wall of the float structure corresponding to the first friction power generation pair is provided with a second friction power generation pair; and when the float structure moves, the first friction power generation pair and the second friction power generation pair rub against each other to generate electricity, and the voltage changes with the change of the position of the float structure. According to the triboelectric type float flow sensing device provided by the invention, the flow of the fluid can be known by detecting the voltage generated by friction power generation, the device is simple in structure, small in power consumption and low in cost, and self-driven can be achieved.

Description

technical field [0001] The invention relates to the technical field of flow detection, in particular to a triboelectric float flow sensing device and flow detection equipment. Background technique [0002] Flow monitoring plays an important role in applications such as automatic control, medical health, energy measurement, flow safety and early warning of pipeline leakage. In the field of flow measurement, the float flow sensor is widely used because of its simple measurement principle and relatively mature technology. However, most of the traditional rotameters are purely mechanical, and there are problems such as complex structure, mechanical wear and mechanical hysteresis; pure electronic and electromechanical hybrid rotameters, because of their relatively high measurement accuracy and relatively low The advantages of wear and tear have been widely used in recent years, but they all require complex control circuits and programs, high power consumption, high cost, and dif...
