Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The wind speed and direction self-driven sensing device OWEH includes at least one friction nano-generator (SE-TENG) with slit effect and an electrometer digital acquisition board, and the friction nano-generator is arranged on the electrometer digital acquisition board.

[0036] Such as figure 1 and figure 2 As shown, the triboelectric nanogenerator is a triboelectric nanogenerator (SE-TENG) based on hydroxyethyl cellulose membrane (HEC) and utilizing the slit effect to amplify wind speed. Each triboelectric nanogenerator includes an air cabin, a triboelectric layer, and a hydroxyethyl cellulose membrane. The air cabin has an inlet port and an outlet port, and the connection line between the inlet port and the outlet port of the air cabin is parallel to, facing The wind direction is arranged, the inlet end of the wind cabin...

Abstract

The invention discloses a wind speed and wind direction self-driven sensing device. The device is composed of eight friction nanometer generators with the slit effect, each friction nanometer generator comprises a wind cabin, a friction electron obtaining layer and a hydroxyethyl cellulose membrane, each wind cabin is provided with an inlet end and an outlet end, and the upper side surface and the lower side surface of the inner wall of each wind cabin are each fixedly adhered with an electrode and the friction electron obtaining layer. A supporting strip which is horizontally arranged and is perpendicular to the wind direction is arranged in the middle, close to the inlet end, of the wind cabin, one end of the hydroxyethyl cellulose membrane is fixedly adhered to the supporting strip, and the other end of the hydroxyethyl cellulose membrane freely extends towards the outlet end; and the eight friction nanometer generators are arranged and fixed on the circumference of the circular ring at intervals of a central angle of 45 degrees along the radial direction, and the eight friction nanometer generators are all connected to an electrometer digital acquisition board. The device has the advantages of being high in sensitivity, wide in effect range and easy to produce, can work stably for a long time, can be used for sensing the wind speed and the wind direction in any direction, and can serve as a sustainable power source of the sensor.

Description

technical field [0001] The invention relates to a wind sensing device, in particular to a self-driven sensing device for wind speed and direction used in agricultural environments. Background technique [0002] As one of the most critical environmental factors in agricultural production, wind can spread plant pollen and seeds, which is beneficial to plant growth and reproduction. In addition, the wind accelerates the rebalancing of oxygen and carbon dioxide concentrations in the air, enhancing crop respiration and photosynthesis. However, some adverse effects of wind on agriculture, such as the spread of pathogens and plant diseases, soil erosion, and damage to crops, have caused huge agricultural production and economic losses worldwide. Therefore, in the process of planting crops, the wind speed and direction in the farmland should be monitored around the clock to prevent large-scale agricultural disasters. In addition, by obtaining accurate wind information, it is possi...
