Description

Dynamic weighing piezoelectric film sensor installation protection device Technical Field The utility model relates to the technical field of installation protection devices, in particular to an installation protection device for a dynamic weighing piezoelectric film sensor. Background The piezoelectric film sensor is a cable-shaped product with the length of about 3-4 m (specifically according to the actual single lane width) and the diameter of less than 5mm, and is arranged on a road surface through pouring sealant when the piezoelectric film sensor is applied, and the width of the groove is cut by about 10mm and the depth of the groove is about 40mm on the road surface. The traditional construction method requires the working procedures of pavement cutting, cleaning, installation, glue filling, solidification and the like. When the existing device is used, under the conditions of potholes, damage and the like of a road surface (cement road surface, asphalt road surface) of an installation scene, the vehicle can bounce when running at a high speed, and the wheels cannot directly and effectively act on the piezoelectric film sensor, so that the measurement accuracy of the system is reduced, and therefore, the installation protection device of the dynamic weighing piezoelectric film sensor is required to be provided. Disclosure of utility model The utility model aims to provide a dynamic weighing piezoelectric film sensor mounting protection device, which is provided with a stainless steel plate, wherein the top surface of the stainless steel plate is flat, and the bottom of the stainless steel plate is provided with a convex structure, so that the stainless steel plate is convenient for transmitting pressure to a sensor body, and the problems in the background art are solved.
