Description

Technical Field

[0001] The utility model relates to the technical field of river channel monitoring, and in particular to a river channel dangerous situation monitoring and early warning device. Background Art

[0002] During the rainy season and flood season, the river water level rises and changes frequently. In order to prevent the water level from exceeding the standard and causing the river to burst its banks, the river needs to be monitored so as to timely grasp the changes in the river water level, and then regulate the river flow, reasonably formulate water storage or flood discharge plans, and improve the flood control capacity of the river embankment. Therefore, river monitoring devices are of great significance in grasping the changes in river water sources and timely warning of flood accidents, avoiding casualties and economic losses, etc.

[0003] At present, the existing river monitoring equipment usually has a whole high profile column, which is easy to collapse during installation and requires the assistance of multiple people. It is not conducive to rapid installation and large-scale control around the river. In addition, the column adopts an integral structure. When encountering stormy weather, due to the effect of wind load, the bending moment of the column is large and it is easy to bend or break. Utility Model Content

[0005] The technical solution of this utility model is as follows:

[0006] A river danger monitoring and early warning device comprises a base, a column is connected to the base, a mounting frame is arranged on the upper part of the column, a rain gauge, a radar water level gauge, a camera and a control box are arranged on the mounting frame, and the column is formed by splicing a plurality of standard columns up and down;

[0007] The standard column includes a vertical pipe, an upper connecting platform is provided on the top of the vertical pipe, a lower connecting cap is provided on the bottom, an arc-shaped positioning groove is provided on the side wall along the circumferential direction, and an arc-shaped guide groove is provided on the top surface of the upper connecting platform. The lower connecting cap can be buckled on the upper connecting platform of the connected standard column, and an insert that cooperates with the inner hole of the vertical pipe is provided on the bottom surface of the connecting cap. A first screw is provided on the outside of the insert for cooperating with the arc-shaped guide groove connected to the standard column, and a positioning hole is provided on the wall of the insert for connecting with the positioning groove of the connected standard column through a second screw.

[0008] In the specific implementation, the standard column is a casting, and the guide groove is an arc groove with a central angle of 180 degrees and the same axis as the upper connecting platform, and is perpendicular to the top surface of the upper connecting platform downward, and the depth is greater than the height of the head of the first screw, so that the first screw on the standard column of the previous section can be inserted into the guide groove during installation and can rotate along the first guide groove. The central angle of the positioning groove is 180 degrees and is located directly below the guide groove. The upper and lower standard columns can produce a relative rotation of 180 degrees, reducing the effect of wind load on the column and avoiding bending or breaking of the column.

[0009] In order to increase the rigidity and stability of the column, two rope rings are symmetrically arranged on the side wall of the riser, located below the positioning groove, and connected to the base through steel wire ropes.

[0010] Specifically, the mounting frame is located on the top standard column. A solar panel is also provided on the top of the top standard column to power the control box. A rain shield is provided on the top of one side of the mounting frame, located above the control box and the camera, to protect the control box and the camera, reduce water ingress from the top surface of the control box, and reduce the occurrence of leakage short circuits.

[0011] In a specific embodiment, an audible and visual alarm is provided on the top of the rain shield to warn pedestrians and staff around when the water level exceeds the warning line, so that they can evacuate in time or take necessary measures. A main control unit is provided inside the control box, which is electrically connected to the rain gauge, camera, radar level gauge and audible and visual alarm, and transmits the collected data to the host computer through a wireless communication module. It is used to transmit the rainfall and water level information collected by the rain gauge, radar level gauge and camera to the monitoring center, so that the staff can formulate corresponding flood prevention or drought relief measures in time.

[0012] The camera is a high-definition night vision camera, which is installed on the mounting frame through a pan / tilt system, making it convenient to conduct all-round monitoring of the river surface at night.

[0013] The beneficial effects of the utility model are:

[0014] The columns adopt a structure in which standard columns are spliced ​​together from top to bottom. The structure is simple, easy to process and mass produce, and easy to install and operate, which is conducive to rapid control over a large area around the river. The exceptional standard columns are rotatably connected, which is conducive to reducing the effect of wind loads on the columns, reducing the possibility of bending or breaking of the columns due to excessive bending moment, and increasing the service life of the river hazard monitoring and early warning equipment.
