The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] See also Figures 1 to 5 , an embodiment of the present application provides a water level measuring device, including a mounting frame 1, an extension frame 2 is slidably connected to the mounting frame 1, a rotating shaft 3 and a rotating shaft 2 5 are rotatably connected to the mounting frame 1, a large gear 4 is installed on the rotating shaft 3, a small gear 21 and a small gear 2 22 are installed on the rotating shaft 2 5, a rack 6 is installed on the extension frame 2, the large gear 4 and the small gear 1 21 are both meshed with the rack 6, and the large gear 4 is not meshed with the small gear 1 21, a mounting seat 7 is slidably connected in the extension frame 2, a rack 2 8 is installed on the mounting seat 7, and the small gear 2 22 is meshed with the rack 2 8, the diameter of the small gear 22 is larger than the diameter of the small gear 1 21, a rotation drive device 9 is installed on the mounting frame 1, the rotation drive device 9 can be a servo motor, the output end of the rotation drive device 9 is transmission-connected to the rotating shaft 3, and a detection mechanism is provided at the bottom of the mounting seat 7.

[0023] In this embodiment, the rotary drive device 9 drives the rotating shaft 3 to rotate, and the large gear 4 on the rotating shaft 3 drives the extension frame 2 to move by engaging with the rack 1 6, so that the extension frame 2 can extend from the mounting frame 1. While the large gear 4 drives the rack 1 6 forward, the rack 1 6 engages with the pinion 21 on the rotating shaft 2 5 and drives it to rotate. Through the engagement of the pinion 2 22 on the same rotating shaft 2 5 with the rack 2 8, and the diameter of the pinion 2 22 is larger than the pinion 1 21, when the pinion 1 21 rotates one circle, the larger diameter of the pinion 2 22 can drive the rack 2 8 to move a greater distance relative to the extension frame 2, so that the rack 2 8 can drive the mounting seat 7 sliding on the extension frame 2 to move outward, so that the detection device on the mounting seat 7 can also be extended. Therefore, by extending both, the water level measurement of a wider river channel is achieved.

[0024] In some embodiments, to facilitate the installation of the ultrasonic water level meter 10, a detection mechanism is provided, including an ultrasonic water level meter 10, an I-block 11 is installed on the ultrasonic water level meter 10, a cross slot 12 is provided on the mounting seat 7, and blocks 13 are slidably connected at both lateral ends of the cross slot 12, and springs 14 are installed in both lateral ends of the cross slot 12, one end of the spring 14 is connected to the block 13, a pull rod 15 is slidably connected to the mounting seat 7, the pull rod 15 corresponds to the block 13 one by one, one end of the pull rod 15 is connected to the block 13, and the I-block 11 and the block 13 are arranged in coordination. When installing the ultrasonic water level meter 10, the I-block 11 on the top of the ultrasonic water level meter 10 squeezes the block 13 in the cross slot 12, so that the block 13 compresses the spring 14 and retracts to both ends of the cross slot 12. Then the I-block 11 continues to move upward and abuts against the top of the cross slot 12. At this time, the block 13 is squeezed out by the spring 14 and stuck on both sides of the I-block 11, so that the ultrasonic water level meter 10 is squeezed and fixed by the I-block 11. When the ultrasonic water level meter 10 needs to be removed, the block 13 is retracted by pulling the pull rod 15, so that the I-block 11 can be pulled out.

[0025] In some embodiments, to protect rack 6, U-shaped telescopic rods 16 are mounted on both ends of mounting frame 1. These rods 16 cooperate with rack 6, with the output ends of the two U-shaped telescopic rods 16 connected to one end of rack 6. As rack 6 moves with extension frame 2, the two U-shaped telescopic rods 16 connected to rack 6 extend or contract, protecting rack 6 from wind and rain.

[0026] In some embodiments, to protect rack 28, U-shaped telescopic rods 17 are mounted on both ends of mounting frame 1. The U-shaped telescopic rods 17 cooperate with rack 28, with the output ends of the two U-shaped telescopic rods 17 connected to one end of rack 28. When rack 28 moves on extension frame 2, it causes the two U-shaped telescopic rods 17 connected to rack 28 to extend or retract, thereby protecting rack 28 from wind and rain.

[0027] In some embodiments, in order to facilitate the installation of the mounting frame 1 on the ground, a mounting plate 18 is installed at the bottom of the mounting frame 1, and a plurality of threaded holes 19 are provided on the mounting plate 18.

[0028] In some embodiments, in order to facilitate the rotation driving device 9 to drive the rotating shaft 3 to rotate, the output end of the rotation driving device 9 is arranged to be transmission-connected to the rotating shaft 3 through a coupling 20.

[0029] In some embodiments, in order to facilitate the clamping block 13 to be squeezed back into the cross clamping slot 12 by the I-shaped block 11, the bottom of the clamping block 13 is provided with a chamfer.
