The floating platform 15 is arranged around the measuring rope 5, and the floating platform 15 is provided with a camera 18 facing the scale lines 9.

[0026] Further, the guiding structure includes a connecting frame 7 arranged on the installation platform 1. One end of the connecting frame 7 close to the wire winding wheel 3 is provided with a first wire guiding wheel 6. There are two first wire guiding wheels 6, and the measuring rope 5 passes between the two first wire guiding wheels 6.

[0027] Further, one end of the connecting frame 7 close to the through hole is provided with a second wire guiding wheel 12. The second wire guiding wheel 12 is installed on the connecting frame 7 through a fixing seat 10. An anti - detachment rod 17 is arranged on the outer side of the second wire guiding wheel 12, and the measuring rope 5 passes between the anti - detachment rod 17 and the second wire guiding wheel 12.

[0028] Further, the pressure sensor 13 is arranged on the fixing seat 10, below the second wire guiding wheel 12. A rubber plate 11 in contact with the second wire guiding wheel 12 is arranged on the pressure sensor 13.

[0029] Further, a plurality of guiding rods 14 penetrating through the installation platform 1 are arranged on the floating platform 15. The floating platform 15 moves closer to or away from the installation platform 1 along the direction of the guiding rods 14.

[0030] Further, the scale lines 9 on the measuring rope 5 are arranged from small to large from the end close to the gravity block 8 to the end close to the wire winding wheel 3.

[0031] Further, a protective cover 16 is covered on the top of the installation platform 1, and an airbag is arranged at the bottom of the installation platform 1.

[0032] In a specific embodiment, such as Figures 1 to 5As shown in the figure, the main body of a water depth measuring device proposed in this application is an installation platform 1. An airbag is provided at the bottom of the installation platform 1, enabling the installation platform 1 to float on the water surface for operation. Two support frames 2 are provided on the installation platform 1, and a wire winding wheel 3 is arranged between the two support frames 2. A measuring rope 5 with scale lines 9 is wound around the wire winding wheel 3. A motor 4 is also provided on the left side of the top of the installation platform 1, and the output shaft of the motor 4 is connected to the wire winding wheel 3, enabling the wire winding wheel 3 to rotate driven by the motor 4, thereby releasing or retracting the measuring rope 5 on the wire winding wheel 3. A protective cover 16 is further provided on the top of the installation platform 1 to protect the internal components.

[0033] A guiding structure is also provided below the wire winding wheel 3. The guiding structure includes a connecting frame 7 provided on the installation platform 1. A first wire guiding wheel 6 is provided at the rear side of the connecting frame 7, and the first wire guiding wheel 6 is located directly below the wire winding wheel 3. A second wire guiding wheel 12 is provided at the front side of the connecting frame 7, and a through hole is opened at the position of the installation platform 1 directly below the second wire guiding wheel 12, and the measuring rope 5 passes through this through hole. And there are two first wire guiding wheels 6. An anti - detachment rod 17 is provided on the outer side of the second wire guiding wheel 12. The measuring rope 5 starts from the wire winding wheel 3, passes through the two first wire guiding wheels 6, then reaches the second wire guiding wheel 12, passes through the gap between the second wire guiding wheel 12 and the anti - detachment rod 17, and then passes downward through the through hole on the installation platform 1 into the water for water level measurement. This design enables the measuring rope 5 to be stably released along the arrangement direction of the first wire guiding wheel 6 and the second wire guiding wheel 12, avoiding errors caused by the loosening or deviation of the measuring rope 5, thus ensuring the accuracy and stability of water level measurement.

[0034] It should be noted that the second wire guiding wheel 12 is installed on the connecting frame 7 through a fixing seat 10. A pressure sensor 13 is also provided on the fixing seat 10. A rubber plate 11 is provided between the second wire guiding wheel 12 and the pressure sensor 13, and the rubber plate 11 is in contact with both the bottom of the second wire guiding wheel 12 and the top of the pressure sensor 13. A gravity block 8 is installed at the end of the measuring rope 5, and the gravity block 8 sinks into the water along with the measuring rope 5. When the measuring rope 5 passes through the second wire guiding wheel 12 and continues to go deeper into the water, the gravity block 8 exerts a downward pressure on the rubber plate 11 below due to its own weight. This design not only helps the measuring rope 5 to maintain a straight state but also ensures the continuity and stability of the measurement process.

[0035] During the process of water depth measurement, as the measuring rope 5 is continuously released, the gravity block 8 gradually approaches the bottom of the water. When the gravity block 8 finally touches the bottom of the water, the pressure it exerts on the rubber plate 11 disappears, indicating that the measured depth has been reached. At this time, the pressure sensor 13 connected to the rubber plate 11 is triggered. There is also a controller on the mounting platform 1 that is electrically connected to the motor 4 and the pressure sensor 13. When the pressure sensor 13 is triggered, the controller controls the motor 4 to stop working, thereby causing the winding wheel 3 to stop rotating and preventing the further release of the measuring rope 5, thus achieving accurate measurement of the water depth.

[0036] Here, a floating platform 15 is movably arranged at the bottom of the mounting platform 1. The bottom of the floating platform 15 is designed as an air cushion, enabling the floating platform 15 to always float on the water surface and change with the water level. The floating platform 15 is a ring surrounding the measuring rope 5. On the inner wall of this ring, a camera 18 is arranged facing the scale line 9 on the measuring rope 5. The scale line 9 on the measuring rope 5 is set to gradually increase from bottom to top. To ensure the stability and guiding property of the floating platform 15 during the floating process, four guiding rods 14 are arranged on one side of the floating platform 15 facing the mounting platform 1. These four guiding rods 14 penetrate through the mounting platform 1, providing stable support and guidance for the floating platform 15, guiding the floating platform 15 to perform linear up and down movement, and ensuring that the floating platform 15 can maintain a relatively stable floating state when fluctuating with the water surface, avoiding the problem of affecting the measurement accuracy due to severe shaking. Under the combined action of buoyancy and the guiding rods 14, the floating platform 15 can automatically adjust its height according to the rise and fall of the water level, approaching or moving away from the bottom of the mounting platform 1, and always maintaining a state parallel to the water surface. The advantage of this design is that the camera 18 can always be located directly above the water surface. No matter how the water level changes, the camera 18 can capture clear images of the scale line 9, improving the accuracy and stability of water level measurement.

[0037] In summary, compared with the prior art, the present application can accurately measure the water depth under the condition of frequent water level changes.

Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
