[0039] The battery 506 is installed inside the warning light 4 , and the battery 506 is used to provide power for the operation of the warning light 4 .

[0040] In this embodiment: when using this device, by placing the fixed rod 1, the movable rod 2, and the floating plate 3 in the water area to be monitored, the outer walls of the fixed rod 1 and the movable rod 2 and the bottom end of the floating plate 3 are in contact with the water. When the water level rises, the floating plate 3 rises due to the buoyancy of the water. The rising floating plate 3 will synchronously drive the movable rod 2 to move upward along the outer wall of the fixed rod 1. The upward moving movable rod 2 will synchronously drive the internal support plate 501 to move upward. The moving pull rod 502 will synchronously drive the pull rod 502 to move upward along the inner cavity of the fixed rod 1. When the pull rod 502 moves to the maximum moving distance, the port at the bottom of the pull rod 502 is aligned with the top of the fixed rod 1. The inner cavity of the end is in contact with the floating plate 3, while the floating plate 3 is still affected by the rising buoyancy. The affected floating plate 3 drives the movable rod 2 to continue to move upward, and the bottom end of the pull rod 502 is restricted. Then the force block 503 at the top of the pull rod 502 will move downward and give an extrusion force to the spring 504 until the spring 504 contacts the button 505, giving the button 505 a downward pressing force. The downward moving button 505 will connect the battery 506 with the power of the alarm light 4, thereby starting the alarm light 4 and completing the early warning. Compared with the fixed rod 1 with a fixed length, this structure can be extended and retracted according to the height of the water level, reducing the impact of wind on the fixed rod 1 and reducing data deviation.

[0041] Please refer to Figure 1-Figure 3 The inner cavity of the movable rod 2 is formed with a slide groove for relative movement of the fixed rod 1, and a sealing ring is provided at the connection between the movable rod 2 and the fixed rod 1. The inner cavity of the fixed rod 1 is formed with a slide groove for vertical movement of the pull rod 502. The outer wall of the pull rod 502 is an inverted "T"-shaped structure as a whole. The alarm light 4, the battery 506, and the button 505 are connected by wires, and the circuit is a series circuit. The outer wall of the floating plate 3 is an overall "cross"-shaped structure. The buoyancy of the floating plate 3 is greater than the gravity of the movable rod 2 and the alarm light 4, and the elastic force of the spring 504 is less than the buoyancy.

[0042] In this embodiment: through this structure, the pull rod 502 can move with the movement of the movable rod 2 until the protruding outer wall at the bottom of the pull rod 502 fits with the top inner cavity of the fixed rod 1, then the continued movement of the movable rod 2 will cause the force block 503 to move downward to give the button 505 an extrusion thrust.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
