Acousto-optic alarm structure for riverway water level exceeding warning line

Abstract

The invention discloses an acousto-optic alarm structure for a riverway water level exceeding a warning line, and relates to the technical field of water conservancy monitoring. The acousto-optic alarm structure comprises a floating plate, a fixed bottom plate, a metal drill bit, a lubricating assembly and a fixed sliding rod, a through hole is formed in the rectangular face of the floating plate, the fixed sliding rod is inserted into the through hole, the top end of the fixed sliding rod is fixedly connected with a top plate, and the bottom end of the fixed sliding rod is fixedly connected with the fixed bottom plate; the lubricating assembly is fixedly connected to the position, corresponding to the through hole, of the floating plate, a connecting rod is fixedly connected to the bottom of the rectangular center of the fixed bottom plate, and a metal drill bit is fixedly connected to the bottom of the connecting rod. According to the invention, a lubricating agent containing box convenient for automatically filling a lubricating agent is fixedly connected to the corresponding position of the fixed sliding rod, a rotating rubber roller drives the lubricating agent to reciprocate on the rotating plate at the bottom of the containing box through the connecting rod in the rotating process, and the lubricating agent is smeared to a rod body of a lubricating column; and the problem that the lubricating column is rusted is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy monitoring, in particular to an acousto-optic alarm structure for river water level exceeding a warning line. Background technique [0002] In many domestic rivers, a water level alarm mechanism is usually set up to monitor the depth of the water level in the flood season in a timely manner, and then take corresponding measures to respond in time through data records to prevent property and personnel casualties after the water level rises rapidly. It is one of the indispensable and important structures in the field of water level monitoring today, but it still has the following disadvantages in actual use: [0003] The existing public document CN210774245U discloses a network alarm device for river water level overrun, including a housing, a water inlet and a water outlet, the right side of the housing is provided with a water inlet, and the bottom of the housing is provided with a water...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an acousto-optic alarm structure for river water level exceeding the warning line, by fixing and connecting the lubricating assembly at the position corresponding to the fixed sliding shaft on the floating plate, and at the same time fixing and connecting the telescopic plug for easy expansion and contraction on the peripheral side of the metal drill bit. column, which solves the problem of poor stability of the existing water level alarm mechanism during installation, and at the same time solves the problem that the existing alarm mechanism will cause the slide bar to rust when it is used for a long time
