[0026] Among them, an opening is provided on one side of the top of the measuring cup 8 to prevent the measuring cup 8 from being damaged due to excessive rainwater in the measuring cup 8. The water in the measuring cup 8 can be poured out through the opening to facilitate measurement of the next rainfall.

[0027] A screen 9 is fixedly mounted on the top side of the funnel 7 to prevent foreign matter from entering the measuring cup 8 through the funnel 7 .

[0028] Among them, the outer side of the monitoring rod 3 is slidably connected to a moving cylinder 10, and a trigger ring 12 is fixedly installed on the top side of the moving cylinder 10. The position of the trigger ring 12 can be flexibly adjusted to adapt to the maximum water level limit of different water conservancy projects. A pressure sensor 13 is fixedly installed on the bottom side of the connecting rod 2 corresponding to the trigger ring 12. When the water level is too high, the trigger ring 12 touches the pressure sensor 13 and transmits a signal that the water level is too high, so that the problem of too high water level can be dealt with in time.

[0029] The movable cylinder 10 is provided with a screw hole, the inner side of the screw hole is threadedly connected with a bolt 11, one end of the bolt 11 is against the outer side of the monitoring rod 3, and the movable cylinder 10 can be conveniently fixed after it moves.

[0030] A limit plate 14 is fixedly installed on the top of the monitoring rod 3 to prevent the monitoring rod 3 from falling off the connecting rod 2.

[0031] Among them, the inner side of the main body 1 is rotatably connected with a screw 15, and the outer side of the screw 15 is threadedly connected to the inner side of one end of the connecting rod 2, which can drive the connecting rod 2 to move flexibly. The screw 15 is connected to the rotating shaft 16 through two sets of bevel gears. One end of the rotating shaft 16 passes through the main body 1 and is fixedly installed with a handle 17, which can conveniently drive the screw 15 to rotate.

[0032] The working principle of this embodiment is as follows: when the water level is too high, the float plate 4 rises driven by the water, and the connecting rod 2 connected to the main body 1 does not move. The float plate 4 drives the trigger ring 12 to move through the monitoring rod 3 and triggers the pressure sensor 13 to send a signal that the water level is too high. After the monitoring personnel arrive at the scene, they take out the funnel 7 and the measuring cup 8 and read the rainfall, so as to quickly check whether the cause of the high water level is excessive rainfall.

[0033] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
