Foundation pit monitoring array distributed composite self-powered sensor
A foundation pit monitoring array distributed composite self-powered sensor provided by the present invention comprises a shell, a guide rod, an elastic piece, a sliding block, a plurality of annular supports and two magnets, the surface of the guide rod is provided with a first nano material friction layer, the middle of the sliding block is provided with a sliding hole, the inner wall of the sliding hole is provided with a first metal electrode, and the sliding block comprises a first fan-shaped block and a second fan-shaped block. A plurality of arc-shaped grids are arranged in the first fan-shaped block, second metal electrodes are arranged on the two opposite sides of the inner wall of each grid, and a plurality of coils are arranged in the second fan-shaped block; second nanometer material friction layers are arranged on the outer wall and the inner wall of each annular support, each grid is penetrated by one annular support, the magnetic pole directions of the opposite ends of the two magnets are opposite, and each coil is located between the two magnets. The beneficial effects of the invention are that the vibration frequency is reflected through the current change; the electric energy generated by friction between the second nano material friction layer and the second metal electrode and the electric energy generated by each coil are stored and then are supplied to the sensor, so that the output power of the sensor can be greatly improved.
本发明提供一种基坑监测阵列分布式复合自供电传感器，包括外壳、导向杆、弹性件、滑块、多个环形支撑和两磁铁，导向杆表面设有第一纳米材料摩擦层，滑块中部设有滑孔，滑孔的内壁设有第一金属电极，滑块包括第一、第二扇形块，第一扇形块内设有多个弧形的栅格，每一栅格的内壁相对两侧均设有第二金属电极，第二扇形块内设有多个线圈；每一环形支撑的外壁和内壁均设有第二纳米材料摩擦层，每一栅格被一环形支撑穿过，两磁铁相对一端的磁极方向相反，各线圈位于两磁铁之间。本发明的有益效果：通过电流变化反映出振动频率；将第二纳米材料摩擦层与第二金属电极摩擦产生的电能和各线圈产生的电能存储后为传感器供电，可大大提高传感器的输出功率。
