Description

Technical Field

[0001] This invention relates to the field of sedimentation monitoring equipment technology, specifically to an underwater visual sedimentation monitoring device. Background Technology

[0002] Over time, rivers and lakes accumulate large amounts of silt in their riverbeds. Excessive silt accumulation can easily affect the original functions of the water bodies.

[0003] Traditional monitoring methods rely on manual labor, with measuring the thickness of sediment deposits in rivers and lakes being a crucial step. Traditional methods often employ methods like the rod-and-spot method and GPS measurements, primarily depending on experience. This makes it difficult to distinguish the actual upper and lower boundaries of the sediment deposits, leading to significant measurement errors. Some methods utilize underwater ultrasonic measurement and drilling, both of which require substantial manpower and resources, resulting in low efficiency. Underwater topographic measurements also suffer from significant errors and low accuracy, failing to meet the demands of today's high-efficiency market. Furthermore, ultrasonic measurements are highly sensitive to the surrounding environment and are currently only carried out by unmanned vessels. Due to the complex underwater environment, the bottom cannot be directly observed through the surface, making the work difficult to implement. Therefore, accurate underwater measurements are extremely challenging, making dynamic sedimentation difficult to achieve. Currently, there is a lack of high-precision measurement equipment on the market that allows for real-time monitoring of underwater dynamics. Summary of the Invention

Detailed Implementation

[0018] This invention provides an underwater visual siltation monitoring device, such as... Figure 1-8 As shown, the system includes an L-shaped pole 1, which is fixed to the riverbank. Slide rails 12 are symmetrically welded to both sides of the L-shaped pole 1, and the slide rails 12 are vertically arranged. A float plate 2 is located at the front of the L-shaped pole 1, and a slider 21 is welded to the rear end of the float plate 2, which slides in conjunction with the slide rails 12. A GPS positioning module 4 is fixedly installed at the front end of the float plate 2, and a transparent monitoring box 3 is fixedly installed at the lower front end of the L-shaped pole 1. A second GPS positioning module 5 is fixedly installed on the top of the monitoring box 3. When the float plate 2 is not in operation, it floats to the highest point of the slide rails 12.

[0019] The L-shaped rod 1 has a cavity 11, and a motor 13 is fixedly installed in the cavity 11. A steel wire 14 is welded to the drive shaft of the motor 13. The end of the steel wire 14 away from the motor 13 extends to the outside of the L-shaped rod 1 and is connected to the slider 21.

[0020] A partition 31 is welded inside the monitoring box 3. A vertical scale 32 is fixedly inserted into the top of the partition 31. A second motor 33 is fixedly installed at the bottom of the monitoring box 3. A vertical threaded rod is welded to the drive shaft of the second motor 33. The top of the threaded rod passes through the partition 31 and is pivotally connected to the top of the inner wall of the monitoring box 3.

[0021] Inside the monitoring box 3 and above the partition 31, there is a sliding block 34. The threaded rod is threadedly connected to the sliding block 34. A camera module 36 is fixedly installed at the front end of the sliding block 34. A transparent film strip 6 is fitted on the front side of the monitoring box 3. The transparent film strip 6 passes through the partition 31 and is tightly attached to the front of the monitoring box 3.

[0022] Work details are attached. Figure 2 As shown, the monitoring box 3 is gradually buried by silt accumulation. Motor 2 33 drives the threaded rod to rotate, causing the moving block 34 to move up and down, and the underwater situation is captured by the camera module 36. The degree of silt burial is indicated by a scale 32. The camera module 36 transmits the silt accumulation thickness indicated by the scale 32 to the outside world.

[0023] A traction roller 37, which drives the transparent film belt 6 to rotate, is fixedly installed inside the monitoring box 3. The traction roller 37 is driven to rotate by a motor.

[0024] The transparent film strip 6 can rotate counterclockwise. A sponge block 38 is fixedly installed at the bottom of the inner wall of the monitoring box 3, and the sponge block 38 is in contact with the surface of the transparent film strip 6.

[0025] Working principle: Since the monitoring box 3 is submerged underwater, its surface inevitably accumulates silt and other dirt. This prevents the camera module 36 from clearly capturing the underwater situation, and the scale 32 indicates the thickness of the silt accumulation. At this time, the traction roller 37 drives the transparent film strip 6 to rotate counterclockwise. The clean transparent film strip 6 moves to the outside of the monitoring box 3, while the dirty transparent film strip 6 is wiped clean by the sponge block 38.

[0026] The aforementioned mechanism effectively removes dirt from the front of the monitoring box 3, enabling the camera module 36 to capture images of the silt. This facilitates comparison between the scale 32 and the silt.

[0027] When excessive silt completely buries the entire monitoring box 3, the camera module 36 cannot capture the boundary between the silt and water, regardless of how the transparent film belt 6 rotates. At this point, the monitor remotely controls motor 13 to rotate. Motor 13 winds steel wire 14, which pulls the float 2 down until it contacts the surface of the accumulated silt. At this point, the float 2 cannot sink further. The distance between the float 2 and the monitoring box 3 is determined by the positional relationship transmitted by GPS positioning modules 1 and 2, thus indicating the height at which the monitoring box 3 is buried by silt.

[0028] A cover 23 is welded to the top of the float plate 2. The float plate 2 has a through groove 22 located directly below the cover 23. The top of the cover 23 has a connection interface 231. A filter plate 24 is fixedly installed in the connection interface 231. Multiple shredding rollers 25 are pivotally connected in the through groove 22. A motor 3 10 is embedded in the float plate 2. The drive shaft of the motor 3 10 is welded to the end of the shredding roller 25.

[0029] A hanging ring 211 is welded to the side of the slider 21. A hook 15 is fixedly tied to the end of the steel wire 14 away from the motor 13. The hook 15 hooks the hanging ring 211. The through groove 22 has symmetrical cuts 221 on the left and right sides. The interface 231 is connected to the sampling tube 26.

[0030] The sampling tube 26 is used to sample the water or silt. An incision 221 is provided to facilitate the entry of silt and river water into the channel 22. A shredder roller 25 is installed to shred branches, leaves, and other debris to prevent blockages during sampling.

[0031] It also includes a photovoltaic module 7, a data collection and transmission module 8, and a control module. The photovoltaic module 7 is fixedly installed on the riverbank. The data collection and transmission module 8 is fixedly installed on the side of the photovoltaic module 7, and the control module is fixedly installed on the top of the L-shaped pole 1. The control module, photovoltaic module 7, and data collection and transmission module 8 are electrically connected. The information fed back by the camera module 36 and the GPS positioning module is transmitted to the computer terminal through the data transmission module 8, facilitating information collection by monitoring personnel.

[0032] The L-shaped pole 1 consists of a longitudinal section and a transverse section. A pin 9 is welded to the bottom of the longitudinal section and is inserted into the riverbed. The top of the longitudinal section is welded to the transverse section, and the transverse section overlaps on the riverbank.

[0033] The bottom of the floating plate 2 is welded with a protrusion 121, and a steel wire 14 passes through the protrusion 121.

[0034] A lighting lamp 35 is fixedly installed inside the monitoring box 3. The lighting lamp 35 serves to provide illumination, facilitating the recording by the camera module 36.

[0035] In summary, this underwater visual siltation monitoring device features intuitive visualization, real-time calculation, and remote monitoring. The monitoring box 3 is submerged to the riverbed using an L-shaped rod 1. Through the coordination of the moving block 34, motor 33, and scale 32, it provides real-time feedback and images of underwater siltation. This provides real-time feedback and intuitive visualization of underwater dynamic measurements, replacing traditional manual submersible monitoring and improving measurement accuracy. The transparent film belt 6, traction roller 37, and sponge block 38 work together to clean dirt from the front of the monitoring box 3. The installation of a float 2, GPS positioning module 4, and GPS positioning module 5 is suitable for situations where silt covers the monitoring box 3, achieving the purpose of auxiliary replacement. This avoids situations where silt covers the monitoring box 3, preventing normal siltation thickness detection.
