The insert rod 11 is located in the vertical rod 4, and the vertical rod 4 is slidably connected to the inner wall of the connecting rod 6. When the vertical rod 4 moves, it is pushed by the return spring 9. When the secondary scale 5 is stored in the main scale 1, the return spring 9 will be compressed, so that the vertical rod 4 is pushed when it moves out next time, driving the secondary scale 5 to move out quickly, and the end of the vertical rod 4 close to the connecting rod 6 is rotatably connected to a clamping plate 10, and the clamping plate 10 is in a straight line shape. The end of the vertical rod 4 away from the fixed seat 3 is fixed with a horizontal plate 20. The connecting rod 6 includes a connecting frame 12, the inner wall of the connecting frame 12 is slidably connected to the vertical rod 4, and bayonet holes 13 are opened on both sides of the connecting frame 12. Bayonet holes 13 are opened on the connecting frames 12 at both ends corresponding to the card plate 10. When the card plate 10 moves to the position of the bayonet hole 13, the card plate 10 can rotate on the vertical rod 4, and the card plate 10 is buckled in the bayonet hole 13. The vertical rod 4 is limited by the card plate 10 and the position will not change.

[0025] The water level observation device for water conservancy and hydropower engineering provided by the utility model has the following working principle: when in use, when it is necessary to measure the deep water level, the clamping plate 10 is first rotated on the vertical rod 4, when the clamping plate 10 moves to a position away from the clamping port 13, the vertical rod 4 slides along the connecting rod 6 under the push of the reset spring 9, and the vertical rod 4 drives the secondary ruler 5 to move when it moves along the connecting rod 6, and when the use is completed or the shallow water level is measured, the secondary ruler 5 is pushed into the main ruler 1, and the secondary ruler 5 is guided by the guide rod 14. When the auxiliary ruler 5 moves from the straight groove 8 to the inclined groove 7, the auxiliary ruler 5 will move left and right on the horizontal plate 20, thereby realizing the change of the position of the auxiliary ruler 5. After the position is changed, the movement trajectory of the auxiliary ruler 5 and the vertical rod 4 will not be limited. Then, the card plate 10 is rotated on the vertical rod 4. When the card plate 10 moves to the position of the card slot 13, the card plate 10 is rotated and the card plate 10 is carded into the card slot 13 for locking and limiting. The auxiliary ruler 5 is retracted into the main ruler 1, thereby reducing the volume of the water level observation device used in water conservancy and hydropower projects, which is convenient to carry.
