Description

Technical Field

[0001] The utility model relates to the field of river water level warning, in particular to a river flood control water level warning device. Background Art

[0002] The river flood control water level is the characteristic water level determined by the water conservancy management agency based on the specific conditions of rivers, lakes, reservoirs, embankments, etc. during the flood control period. When the water level exceeds this characteristic water level, it is necessary to enter the defense stage, that is, the flood control stage.

[0003] During the flood season, there will be a large amount of precipitation, and timely flood prevention preparations will be made by understanding the river water level conditions. The existing river flood prevention water level warning generally fixes a pole in the water and marks the flood prevention water level on the pole. The water level of the river can be judged by observing the distance between the flood prevention water level and the water surface. However, at night, there is insufficient light outside, making it inconvenient to observe changes in the river water level and inconvenient for preparations for flood prevention work.

[0006] As a further description of the above technical solution:

[0007] The outer surface of the fixing rod is threadedly connected with a thread ring, and the inner surface of the thread ring is fixedly connected with an inner ring.

[0008] As a further description of the above technical solution:

[0009] A slot is formed on the top of the connection cover, and the inner ring is installed inside the slot.

[0010] As a further description of the above technical solution:

[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, the river flood control water level warning device, through the connection cover, floating plate, fixed block, metal block, electrode sheet, indicator light, when in use, the floating plate will float on the water surface, and change with the change of water level height. When the water level rises to the warning position, the floating plate will move upward with the fixed block. At this time, the metal block on the fixed block will contact the electrode sheet to connect the circuit, and the indicator light will light up. At night when the light is insufficient, the height of the river water level can be judged by observing the state of the indicator light. Compared with the conventional river flood control water level warning device, the external light is insufficient at night, and it is inconvenient to judge the water level of the river by observing the distance between the mark on the pole and the water surface, which is not conducive to the preparation of flood control work. The indicator light of the river flood control water level warning device will emit light after the water level reaches the warning position. At night, the height of the river water level can be judged by observing the state of the indicator light, which is easy to use.

[0018] 2. Compared with the prior art, this river flood control water level warning device uses multiple electrode plates and multiple indicator lights. When in use, different water levels will cause the floating plate to move upward by different distances, allowing the metal plate to contact different electrode plates, so that the indicator lights can emit different lights according to the changes in the water level, which is convenient for judging the water level at night.
