Four cross rods 5 are arranged in the lower water level measuring tube 1, and the four cross rods 5 are all rotationally connected with the four L-shaped plates 4. A worm wheel 6 and a U-shaped plate 7 are fixedly sleeved on each of the four cross rods 5, and the four worm wheels 6 are respectively located in the four U-shaped plates 7. Two conical rods 25 are fixedly installed at the bottom of each of the four U-shaped plates 7. A worm 3 is rotationally installed on the inner wall of the bottom of the lower water level measuring tube 1, and the worm 3 is engaged with the four worm wheels 6. A connecting rod 9 is fixedly installed at the top end of the worm 3. In order to make the connecting rod 9 rotate more stably in the lower water level measuring tube 1, a stabilizing plate 2 is rotationally sleeved on the connecting rod 9, and the stabilizing plate 2 is fixedly connected with the lower water level measuring tube 1. An external thread sleeve 14 is fixedly sleeved on the connecting rod 9. An internal thread sleeve 15 is threadedly sleeved on the external thread sleeve 14. An upper water level measuring tube 10 is fixedly sleeved on the internal thread sleeve 15. The top of the upper water level measuring tube 10 is fixedly installed with a fixed box 17. A recess is formed in the top of the connecting rod 9, and a first limiting plate 11 is slidingly installed in the recess. In order to limit the first limiting plate 11, the first limiting plate 11 is rotated to drive the connecting rod 9 to rotate. The connecting rod 9 is rotated to drive the external thread sleeve 14 to rotate, so that the external thread sleeve 14 is separated from the internal thread sleeve 15, and the storage work of the device is completed. Two limiting grooves are formed in the inner wall of the recess. The two sides of the first limiting plate 11 extend into the two limiting grooves and are slidingly connected with the inner walls of the two limiting grooves, respectively. A rotating rod 12 is fixedly installed at the top of the first limiting plate 11. In order to make it more convenient for people to rotate the rotating rod 12, a rotating handle 21 is fixedly installed at the top end of the rotating rod 12, and an anti-skid sleeve is fixedly sleeved on the rotating handle 21. The anti-skid sleeve prevents people from slipping when rotating, which affects the work efficiency. The rotating rod 12 penetrates through the fixed box 17 and is rotationally connected with the fixed box 17.
[0028] In order to determine whether the device is vertically inserted into the river bottom, and further improve the accuracy of water level measurement, the second bevel gear 19 is fixedly sleeved on the rotating rod 12, and two winding rods 20 are rotatably installed in the fixed box 17. In order to rotatably install the winding rod 20 in the fixed box 17, two rotating holes are formed in the inner wall of the fixed box 17, the two ends of the two winding rods 20 extend into the two rotating holes respectively and are fixedly sleeved with bearings, and the outer rings of the two bearings are fixedly connected with the inner walls of the two rotating holes respectively. The bearings make the winding rod 20 rotate more stably in the fixed box 17. The first bevel gear 18 is fixedly sleeved on the two winding rods 20 respectively, and the two second bevel gears 19 are engaged with the two first bevel gears 18 respectively.

The outer wall of the upper water level measuring pipe 10 is marked with a plurality of alignment scale lines 24. Since the gravity is vertically downward, under the action of the gravity of the tapered counterweight 23, the marking line 22 is vertically downward. When the marking line 22 is parallel to the alignment scale line 24, it means that the device is perpendicular to the river like the marking line 22, so the device is vertically inserted into the river bottom. When the marking line 22 is not parallel to the alignment scale line 24 and is inclined, it means that the device is not perpendicular to the river and is in an inclined state, so that people re-adjust the device to make it vertically inserted into the river bottom, and further improve the measurement accuracy.
[0029] In order to limit the left and right of the inner threaded sleeve 15, and further make the outer threaded sleeve 14 rotate while the inner threaded sleeve 15 remains unchanged, and further make the outer threaded sleeve 14 move downward when rotating, the inner wall of the lower water level measuring pipe 1 is provided with two limiting sliding grooves, and the outer wall of the upper water level measuring pipe 10 is fixedly installed with two second limiting plates 16, and the two sides of the two second limiting plates 16 extend into the two limiting sliding grooves respectively and are slidably connected with the inner walls of the two limiting sliding grooves respectively.
[0030] In order to make people carry the device, pull the connecting rod 9, the fixed box 17 and the upper water level measuring pipe 10 to move downward into the lower water level measuring pipe 1, and further make the volume of the device smaller, so that people can carry the device more conveniently, the first limiting plate 11 is fixedly installed with the elastic pull rope 13 at the bottom. In order to improve the service life of the elastic pull rope 13, the elastic pull rope 13 is a TPU spring rope, and the bottom end of the elastic pull rope 13 is fixedly connected with the bottom inner wall of the groove.
[0031] The working principle of the water level measuring device for water conservancy projects is as follows: in the initial state, the elastic pull rope 13 is in a stretched state, when people need to use the device, the device is directly placed into the river channel, the four conical rods 25 are inserted into the bottom of the river channel, due to the action of gravity being vertically downward, the plumb line 22 is vertically downward under the action of the gravity of the conical counterweight 23, when the plumb line 22 is parallel to the alignment scale line 24, it indicates that the device and the plumb line 22 are both perpendicular to the river channel, so the device is vertically inserted into the bottom of the river channel, when the plumb line 22 is not parallel to the alignment scale line 24 and is inclined, it indicates that the device is not perpendicular to the river channel and is in an inclined state, so that people re-adjust the device to make the device be vertically inserted into the bottom of the river channel, thereby improving the measurement accuracy, meanwhile, since the device is inserted into the bottom of the river channel through the four conical rods 25, the contact area with the soil of the bottom of the river channel is greatly increased, thereby making the device more stable in the river channel, when people do not need to use the device, the rotating handle 21 is rotated, the rotating handle 21 drives the second bevel gear 19 to rotate, the second bevel gear 19 drives the two first bevel gears 18 to rotate, the two first bevel gears 18 drive the two winding rods 20 to rotate, the winding rod 20 winds the plumb line 22, meanwhile, the rotating rod 12 drives the first limiting plate 11 to rotate, the first limiting plate 11 drives the connecting rod 9 to rotate, the connecting rod 9 drives the outer threaded sleeve 14 to rotate and move downward, when the outer threaded sleeve 14 moves downward and no longer contacts the inner threaded sleeve 15, the first limiting plate 11 is driven by the elastic pull rope 13 to move downward, thereby driving the connecting rod 9, the fixed box 17 and the upper water level measuring pipe 10 to move downward into the lower water level measuring pipe 1, the device is stored, the overall volume of the device is reduced, thereby making people carry the device more conveniently.
