Abstract

The invention provides a rainfall collision force measurement device, belonging to the technical field of sensors. The device comprises a substrate, insulating sheets, a piezoelectric ceramic sheet, abase, rain block plates a, rain block plates b, hollow cylinders, an annular support, stream stabilizing plates, rain block plates c, drainage ports, supports, a flexible material, a bottom plate, foot screws, a seat, a roller, a support base, water-proof silicon rubber, a drain plate, a wire, and chutes. Innovatively, the device takes multiple water-proof measures such as blocking by the rain block plates and covering by the water-proof silicon rubber, and measures rainfall collision force in a water covering environment; the stream stabilizing plates minimize measurement error caused by vertical wind; the foot screws, the roller support and a special shaped piezoelectric ceramic sheet help reduce inclination of a working surface of the sensor, so that the device measures rainfall collision force in vertical direction more accurately.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a rainfall impact force measurement device. Background technique [0002] Rainfall will produce collision force on vegetation or building structure, and rainfall collision force will have a scouring effect on vegetation or soil, causing water and soil loss; rainfall collision force acting on the building structure will cause internal force of the structure, affecting the durability of the structure, and even Threat to the security of the structure. Therefore, it is very necessary to study the rainfall collision force. [0003] Currently, sensors are mainly used to measure the impact force of rainfall, especially piezoelectric ceramic sensors. The so-called piezoelectric effect means that when pressure or tension is applied to the piezoelectric ceramic sheet, charges with opposite polarities will be generated at both ends of it, and a current will be formed through the circuit. ...
