In the above structure, the limit rod 5 is located on the inner wall of the vertical plate 2, and the limit rod 5 penetrates the bottom of the support block 4. The support block 4 is limited by the limit rod 5, so that the limit rod 5 can only move up and down at the top of the support block 4.

[0023] In a preferred embodiment, a round rod is provided on the inner wall of the support block 4, and the round rod passes through the magnetic block 2 13. The outer wall of the round rod on the inner wall of the support block 4 is slidably connected to the inner wall of the magnetic block 2 13. In the above structure, the magnetic block 2 13 is limited by the round rod provided on the inner wall of the support block 4, so that the magnetic block 2 13 can only slide on the outer wall of the round rod on the inner wall of the support block 4.

[0024] In a preferred embodiment, magnetic block 2 13 is arranged parallel to magnetic block 10, and the corresponding surfaces of the two are both S poles. In the above structure, when magnetic block 10 moves upward to the same height as magnetic block 2 13 through the buoyancy of floating block 9, the S poles of magnetic block 2 13 and magnetic block 10 are relative, so that magnetic block 2 13 moves in the opposite direction of magnetic block 10 on the inner wall of support block 4.

When the lock slot 16 moves to the bottom of the lock pin 18, the lock pin 18 is pushed downward to the inner wall of the lock slot 16 through the rebound of the spring three 19, and the lock slot 16 is locked, so that the pull rod 14 is separated from the hole on the outer wall of the limit rod 5. At this time, the support block 4 is pulled upward, so that the support block 4 as a whole moves up and down on the outer wall of the limit rod 5. When it moves to the target height, the pull pin 17 is pulled upward, so that the lock pin 18 moves upward, and then the lock pin 18 is separated from the lock slot 16. At this time, the pull rod 14 is reset by the rebound of the spring two 15, so that the pull rod 14 enters the limit The hole on the outer wall of the positioning rod 5 is used to fix the height of the support block 4 and complete its installation. When the water level inside the water storage point rises, the buoyancy of the floating block 9 drives the magnetic block 10 upward. When the magnetic block 10 moves upward to the same height as the magnetic block 2 13 through the buoyancy of the floating block 9, the S poles of the magnetic block 2 13 and the magnetic block 10 are opposite, so that the magnetic block 2 13 moves in the opposite direction of the magnetic block 10 on the inner wall of the support block 4, thereby moving the extension block at the bottom of the magnetic block 2 13, thereby driving the rotating end of the power switch 21 to rotate, thereby rotating the power switch 21, so that the battery 11 is energized, and the buzzer 6 and the alarm light 7 are powered, so that the buzzer 6 buzzes.
