Embodiment 1

[0037] The present invention designs a self-powered liquid flow meter, and the technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific examples:

[0038] figure 1 Shown is an exploded schematic diagram of the basic structure of the self-powered liquid velocity meter of the present invention, figure 2 It is a schematic diagram of the overall structure of the self-powered liquid flow meter of the present invention. The flow meter includes: a housing 15, a turbine 13, a transmission shaft 14, a frictional nanometer generating mechanism 20, an energy storage mechanism 19, a digital display screen 2, and a pipeline system; wherein the housing 15 is a cylindrical cavity structure, and the cavity structure is The isolation plate 4 and the sealing plate 11 arranged successively from top to bottom are divided into an upper chamber, a middle chamber and a lower chamber 18; the energy storage mechanism 19 and the...

Embodiment 2

[0048] This embodiment is improved on the basis of Example 1. As a preferred embodiment of the present invention, on the basis of a self-powered liquid flow meter, a hydraulic sensor is set on the liquid inlet pipeline and the liquid outlet pipeline to form a New multifunctional liquid meter. The hydraulic sensor line passes out of the liquid inner cavity through the inner cavity of the flow meter, the sealing plate and the sealing hole on the sealing plate, and then connects to the circuit module in the circuit chamber through the friction nano power generation mechanism, the center hole of the friction plate and the line hole 5, Finally, the hydraulic information is converted into digital information and displayed on the display screen. The new multi-purpose self-powered liquid flow meter can also be used as a liquid meter. The invention can also be used as a liquid meter to measure the liquid temperature. A temperature sensor is embedded on the sealing plate of the inner c...

Embodiment 3

[0051] This embodiment is improved on the basis of Example 2. As a preferred embodiment of the present invention, on the basis of a self-powered liquid flow meter combined with GPS positioning technology, the network terminal replaces humans to realize automatic meter reading, thereby realizing The global network control of the entire water pipeline, through the collection and judgment of pipeline hydraulic temperature and other information, can detect pipeline resistance or liquid abnormalities in time, so that timely maintenance can be performed, and the impact of pipeline abnormalities on the pipeline system can be minimized as much as possible. In the present invention, the multi-purpose self-powered liquid flow meter has a collector inside, which can save the water meter data and intelligently transmit it to the Internet, and analyze and process the data through the background software operating system to form a smart water system.

Abstract

The invention discloses a self-powered liquid pitometer, and the pitometer comprises a housing, a turbine, a transmission shaft, a frictional nano-generator mechanism, an energy storage mechanism, a digital display screen, and a pipe system. The housing is of a cylindrical cavity structure, and the cavity structure is divided into an upper cavity, a central cavity, and a lower cavity. The interior of the upper cavity is fixedly provided with an energy storage mechanism and an integrated circuit structure, and the energy storage mechanism is electrically connected with the frictional nano-generator structure through a line hole on a separation plate. The integrated circuit is used for data conversion, and is connected with a digital display screen embedded on the upper surface of the housing. The interior of the central cavity is provided with the frictional nano-generator mechanism, and the frictional nano-generator structure comprises an upper frictional sheet and a lower frictional sheet, which are arranged coaxially and have the same size. The lower frictional sheet is connected with a turbine shaft through the transmission shaft, and makes synchronous rotation movement with the turbine. The interior of the interior of the lower cavity is provided with the turbine, and a side wall of the cavity is connected with the pipe system which comprises a liquid incoming pipe and a liquid outgoing pipe.

Description

technical field [0001] The invention relates to the field of instruments and meters, in particular to a self-powered liquid flowmeter. Background technique [0002] With the rapid development of modern industry and information industry, the demand for common industrial instruments such as flow meters, liquid pressure, and thermometers has been rising year after year. Traditional testing instruments are mostly powered by batteries. The extensive use of battery products not only consumes a lot of energy, waste batteries The follow-up treatment of the environmental protection field has also become an urgent problem to be solved. In order to reduce environmental energy consumption, the design and research of new functional solutions for instruments and meters has become a key research direction for scholars at home and abroad. [0003] Triboelectric nanogenerator (TENG) is a new type of generator developed by Professor Wang Zhonglin's research group at Georgia Institute of Tech...
