Embodiment Construction

[0017] refer to Figure 1-Figure 6 As shown, the present invention provides a piezoelectric sensor, which includes a piezoelectric assembly and a fixed steel frame 1 for fixing the piezoelectric assembly. The piezoelectric assembly includes a plurality of piezoelectric rulers 2 and two steel rails 3 . The rail 3 is a circular tubular hollow rail, and the two rails 3 are arranged opposite to each other. There is a groove 4 on one side of the rail 3, and the grooves 4 of the two rails are placed opposite to each other. There are multiple fixed joints 13 in the groove 4, and the two ends of the piezoelectric ruler are respectively inserted into the fixed joints 13 of the steel rails on both sides and fixed by epoxy resin glue. The epoxy resin adhesive uses 3M-DP460 epoxy resin adhesive to prevent it from falling off due to vibration during use. The distance between adjacent fixed joints 13 is 50MM. A plurality of piezoelectric rulers 2 are respectively fixed between two steel r...

Abstract

The invention discloses a piezoelectric sensor, which comprises a piezoelectric assembly and a fixing steel frame for fixing the piezoelectric assembly, wherein the piezoelectric assembly comprises aplurality of piezoelectric rulers and two steel rails, the two steel rails are oppositely arranged, the piezoelectric rulers are fixed between the two steel rails respectively, the steel rails and thepiezoelectric rulers are combined to form a ladder shape, the outer ends of the steel rails are wrapped with abrasive paper, the upper ends and the lower ends of the steel rails are fixed to the corresponding fixing steel frames respectively, and the piezoelectric assembly is connected with an electric energy storage box and a side slope early warning monitoring system through conducting wires respectively. According to the invention, the pressure sensor is high in precision and high in practicability, the piezoelectric ruler generates electric energy through bending deformation, the electricenergy is provided for a slope early warning monitoring system, self power supply is achieved, and cost is saved.

Description

technical field [0001] The present invention relates to a piezoelectric sensor, and also relates to a method for self-powered monitoring of dam slope collapse by the piezoelectric sensor. engineering field. Background technique [0002] With the improvement of our country's economy and the rapid development of transportation, more and more roads have been built in our country. As of the end of 2019, the total mileage of my country's highways has ranked first in the world. In recent years, my country's highway construction has developed rapidly, and the status of road transportation in the development of the national economy has become increasingly prominent, and it has become an important part of the country's economic construction. It took only more than 20 years for our country to complete the expressway development achievements achieved by developed countries in more than half a century at an astonishing speed. [0003] Because a large number of roads have been built i...
