Roadway drainage pipeline leakage online monitoring device

Abstract

The utility model discloses a roadway drainage pipeline water leakage on -line monitoring devices relates to monitoring device technical field, including setting in the mounting bracket of groove upper end still include: swing rod sensor, set in mounting bracket upper end, elastic card piece, set in the fixed ladder type bottom plate of groove inboard upper end, when the water flow of groove inboard has the flow, the water flow extrusion is connected on the V type tab of ladder type bottom plate upper end, and V type tab pushes its front end fixed extrusion rod, and extrusion rod extrusion pushes elastic card piece and the water baffle bottom part of swing rod sensor one side set swing rod lower end and separates, and then through the water baffle drive swing rod sensor rotates to make sensor transmission signal alarm, and the device can detect the water leakage condition fast and accurately, and timely sends out the alarm signal, and lets the maintenance personnel know and handles the problem in the first time, and effectively avoids the problem such as roadway ponding caused by not finding in time because of water leakage.

Claims

1. An online monitoring device for water leakage in roadway drainage pipes, comprising a mounting frame (1) installed at the upper end of a trench, characterized in that, Also includes: A swing arm sensor (2) is mounted on the upper end of the mounting bracket (1); The elastic clip (3) is set on the upper end of the trapezoidal base plate (4) fixed inside the trench. When there is water flowing inside the trench, the water flow squeezes the V-shaped protrusion (5) connected to the upper end of the trapezoidal base plate (4). The V-shaped protrusion (5) pushes the squeezing rod (6) fixed at its front end. The squeezing rod (6) squeezes and pushes the elastic clip (3) to separate from the bottom of the water baffle (7) at the lower end of the swing arm on one side of the swing arm sensor (2). Then, the water baffle (7) drives the swing arm sensor to rotate, thereby causing the sensor to transmit a signal alarm.

2. The online monitoring device for water leakage in roadway drainage pipelines according to claim 1, characterized in that, The elastic clip (3) includes a pad (31) fixed to the trapezoidal base plate (4) away from the inclined end, and a vertical slide rod (32) is fixed to the upper end of the pad (31).

3. The online monitoring device for water leakage in roadway drainage pipelines according to claim 2, characterized in that, The upper end of the vertical slide rod (32) is slidably sleeved with an abutment block (33), and a compression spring (34) sleeved on the outside of the vertical slide rod (32) is connected between the abutment block (33) and the gasket (31).

4. The online monitoring device for water leakage in roadway drainage pipelines according to claim 3, characterized in that, The rear of the contact block (33) is fixed with a trapezoidal pressure block (35) that can cooperate with the extrusion rod (6) to contact and extrude.

5. The online monitoring device for water leakage in roadway drainage pipelines according to claim 1, characterized in that, The trapezoidal base plate (4) has its inclined surface facing away from the end of the elastic clip (3).

6. The online monitoring device for water leakage in roadway drainage pipelines according to claim 1, characterized in that, The V-shaped convex plate (5) includes two sets of guide plates (51) that are rotatably connected to each other. One set of guide plates (51) near the inclined end of the trapezoidal base plate (4) is rotatably connected to the trapezoidal base plate (4), and the other set of guide plates (51) has sliders (52) integrally formed on both sides of its ends. The sliders (52) slide directionally along the groove of the groove rod (53) fixed to the inner wall of the groove.
