[0025] Please see Figure 1-5This utility model provides a technical solution: a water level measuring device, including a foam float plate 1, a protective frame 8, and a motor waterproof cover 9. The foam float plate 1 has an opening 2 in the middle, and water-blocking plates 3 are fixed at the four corners of the foam float plate 1. The bottom of each water-blocking plate 3 is inclined to facilitate blocking water waves. Water-dissipating wave components 4 are installed on all four sides of the foam float plate 1. The water-dissipating wave components 4 include a support plate 401, a connecting shaft 402, a rotating cylinder 403, and a rotating blade 404. The support plate 401 is fixed to both ends of one side of the foam float plate 1. A connecting shaft 402 is fixed between the support plates 401, and a rotating cylinder 403 is evenly rotatably connected to the surface of the connecting shaft 402. A rotating blade 404 is evenly fixed to the surface of the rotating cylinder 403, so that the water waves can be offset by the rotatable rotating cylinder 403 and rotating blade 404, reducing the transmission of water waves. L-shaped support columns 5 are glued to both sides of the opening 2 in the middle of the foam floating plate 1. The interior of the L-shaped support column 5 is hollow, which can be used in conjunction with the drainage pipe 1703 and the water distribution pipe 1704 to drain water into the L-shaped support column 5.

[0026] Please see Figure 1-5 A sliding cylinder 6 is fixed between two sets of L-shaped support columns 5. A measuring rod 7 is connected to the sliding cylinder 6. The sliding cylinder 6, the protective frame 8, and the measuring rod 7 are all slidably connected. A base plate 12 is fixed to the bottom of the measuring rod 7, and pins 13 are evenly installed on the lower surface of the base plate 12 to facilitate the insertion of the measuring rod 7 into the riverbed. The measuring rod 7 includes a rod body 701, scale lines 702, and toothed blocks 703. Scale lines 702 are provided on both the front and rear sides of the rod body 701, and toothed blocks 703 are fixed to both the left and right ends of the rod body 701. The scale lines 702 facilitate water level measurement, and the toothed blocks 703 can mesh with the transmission gear 1003 to achieve the purpose of lifting and lowering. A protective frame 8 is fixed above the L-shaped support column 5, and a motor waterproof cover 9 is installed on one side of the protective frame 8. A transmission assembly 10 is installed inside the protective frame 8. The transmission assembly 10 includes a vertical plate 1001, and the vertical plate 1001 is provided with two Each set of upright plates 1001 has two sides and is fixed above the L-shaped support column 5. The middle of the upright plate 1001 is rotatably connected to a rotating shaft 1002, and the surface of the rotating shaft 1002 is fixed with a transmission gear 1003 between the upright plates 1001. One end of the rotating shaft 1002 passes through the protective frame 8 and is connected to a servo motor 1004 fixed inside the motor waterproof cover 9. The two sets of rotating shafts 1002 are connected by a transmission belt 1005, which is arranged in a figure-eight shape. The servo motor 1004 can drive the rotating shaft 1002 to rotate. With the use of the transmission belt 1005, the transmission gear 1003 can rotate. The two sets of transmission gears 1003 are meshed with the toothed blocks 703 on the surface of the rod 701, which facilitates the meshing movement of the transmission gears 1003 and the toothed blocks 703 on the surface of the rod 701.

[0027] Please see Figure 1-5 The foam floating board 1 has an inner cavity 14 located in the middle of one side of the opening 2. A water level monitoring camera 15 is installed inside the inner cavity 14. A waterproof lens 16 is installed at the end of the inner cavity 14 on the foam floating board 1. A flushing assembly 17 is installed inside the foam floating board 1. The flushing assembly 17 includes a water pump 1701, which is fixed to the foam floating board 1. One end of the water pump 1701 is connected to a water suction pipe 1702 that passes through the gap between two adjacent sets of baffles 3. The other end of the water pump 1701 is fixed with a drain pipe 1703 that is connected to the bottom of the L-shaped support column 5 on one side. The surface of the drain pipe 1703 is connected with a water distribution pipe 1704 that is connected to the bottom of the L-shaped support column 5 on the other side. Both the upper and lower sides of the L-shaped support column 5 are equipped with flushing heads 1705. The flushing heads 1705 are both inclined and their inclination directions are opposite, so that the two sets of flushing heads 1705 can flush the measuring rod 7 and avoid the adhesion of dirt and sludge.

[0028] Working principle: First, when in use, the device is floated on a river or lake. When water waves come, they first pass through the wave-dissipating component 4, causing the rotating blades 404 on the surface of the rotating cylinder 403 to rotate under the impact of the water waves, so that most of the water waves are blocked and canceled out. In addition, with the setting of the inclined baffle plate 3, it is convenient to block some small water waves that have passed through the wave-dissipating component 4, so that the water surface inside the opening 2 in the middle of the foam floating plate 1 is calm, thereby improving the accuracy of water level measurement.

[0029] During measurement, the servo motor 1004 can be turned on, causing it to drive the transmission gear 1003 to rotate via the rotating shaft 1002. With the use of the figure-eight shaped transmission belt 1005, the two sets of transmission gears 1003 can synchronously drive the toothed blocks 703 on both sides of the rod body 701 of the measuring rod 7 to mesh, so that the rod body 701 slides downward, allowing the bottom plate 12 and the pin 13 at the bottom of the measuring rod 7 to enter the water surface. With the use of the water level monitoring camera 15 in the middle of the foam floating plate 1, the water level data can be transmitted to the external display surface for observation of the water level measurement data.

[0030] After the measurement is completed, when the measuring rod 7 is reset, the water pump 1701 on the flushing assembly 17 can be turned on so that the water pump 1701, together with the use of the water pumping pipe 1702, the drainage pipe 1703 and the water distribution pipe 1704, can discharge the water on the river surface into the L-shaped support column 5. This allows the two sets of flushing heads 1705 on the L-shaped support column 5 to flush the measuring rod 7, preventing scale and sludge from affecting the service life of the measuring rod 7. This is the operating principle of the water level measuring device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
