Description

Technical Field

[0001] The utility model relates to the technical field of underwater video detection devices, in particular to an underwater video detection device and an application method thereof. Background Art

[0002] Pipeline CCTV inspection utilizes closed-circuit television (CCTV) cameras to inspect and evaluate the interior of pipelines. It primarily monitors the condition of pipelines, specifically cracks, deposits, blockages, corrosion, and other issues that could affect their function. This technology is widely used in municipal engineering, building maintenance, and the oil and gas industry.

[0003] The conventional pipeline CCTV inspection process is as follows: Before using the CCTV inspection robot for inspection, it is often necessary to use air bags to seal both sides of the pipe section to create dry conditions for the drainage pipe and ensure that the CCTV inspection robot can detect the distribution of defects inside the pipe section.

[0004] Although traditional CCTV detection technology is widely used in pipeline inspection, it still has the following significant disadvantages:

[0005] 1) Image acquisition distance is unstable:

[0006] The distance between a traditional CCTV robot camera and the pipe wall can vary depending on internal pipe conditions, such as sediment and unevenness. This unstable distance can lead to inconsistent image clarity and detail, hindering accurate disease identification and assessment.

[0007] 2) Limited accuracy of disease identification:

[0008] Due to the certain distance between the camera and the pipe wall, some subtle defects such as tiny cracks and initial corrosion are difficult to be captured clearly, resulting in an increased risk of missed detection or misjudgment.

[0009] 3) Lack of adaptability:

[0010] When there are bends, branches or complex structures in the pipeline, traditional CCTV robots may find it difficult to maintain a stable trajectory and image quality, affecting the overall detection effect.

[0011] 4) The authenticity of the video material is limited:

[0012] When there is water flowing or accumulating in the pipeline, the presence of water may cause image blur, reflection and other problems, affecting the camera's true reflection of pipe wall defects.

[0013] 5) High operational complexity:

[0014] When traditional inspection robots need to conduct detailed inspections of specific disease points, they often lack effective means to fix the camera position, resulting in the need for multiple adjustments and operations, increasing inspection time and labor costs.

[0015] 6) Difficulty of data processing and analysis:

[0016] Due to the uneven image quality, subsequent data processing and disease analysis require higher technical requirements, which increases the complexity and cost of the overall detection system.

[0017] 7) Due to the high groundwater level in coastal cities, it is difficult to create dry storage conditions by blocking pipeline leakage.

[0018] In summary, there is an urgent need to develop CCTV detection technology when the drainage network is running with water. Utility Model Content

[0019] The purpose of the utility model is to provide an underwater video detection device and its application method for a drainage network test base that can simulate various operating scenarios of existing drainage pipelines and is used for equipment integration research, process testing, and operation simulation of the pipeline "monitoring, inspection, evaluation, repair, and maintenance" process.

[0020] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0021] An underwater video detection device,

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The utility model provides transparent airbags on both sides of the high-definition camera. The transparent airbags are connected to an external air source through an air tube and can be inflated and deflated. When the transparent airbags are inflated, they can fit tightly against the inner wall of the pipe, thereby firmly fixing the position of the high-definition camera. This design not only ensures the stability of the high-definition camera in the pipe, but also effectively prevents the camera from being offset due to pipe vibration or water flow impact, ensuring the stability and clarity of the captured image.

[0024] (2) The utility model adjusts the shooting range of the high-definition camera longitudinally and the shooting angle of the high-definition camera 360 degrees through the lifting bracket and the rotating shaft mechanism.

[0025] (3) The spiral drum design of the present invention facilitates the free movement of the present invention in a drainage pipe full of water. The shape and structure of the spiral drum enable it to automatically adapt to the water pressure and resistance in the pipe when flowing in the pipe. Through rolling and friction, it pushes the device to move in the water flow, which not only ensures that the camera can be smoothly advanced in environments with different water levels, but also automatically adjusts its direction when encountering obstacles, thereby ensuring the stable operation of the camera in complex pipe environments.

[0026] (4) The present invention can enhance the light source of the high-definition camera 7 in the pipeline by using a fill light, so that the high-definition camera can still clearly capture the details inside the pipeline in low-light or dark environments, avoiding the situation where the image is blurred or cannot be clearly identified due to insufficient light. This design improves the camera's adaptability in complex and dim environments, ensuring that high-quality image data can be obtained in any situation. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] like Figure 1 As shown, an underwater video detection device provided by this embodiment is used to evaluate pipeline network diseases, including a data transmission pan-tilt platform 4, a driving walking mechanism, a shooting mechanism and an airbag mechanism.

[0032] The data transmission pan-tilt head 4 transmits data to a database through a PLC control system for aggregating and storing videos and photos of the shooting mechanism, and transmits them to the PLC control system for evaluation. The PLC control system is used to control the operation of the drive unit, the rotating shaft mechanism, the data transmission pan-tilt head 4, the lifting bracket 3 and the high-definition camera 7.

[0033] The PLC control system transmits data to the database in real time for subsequent storage and analysis. Various road disease models are pre-established and collected in the database for comparison and diagnosis.

[0034] The driving mechanism is connected to the data transmission platform 4 via a bracket, providing a travel function. It comprises two sets of spiral rollers 1 and a drive unit. The two sets of spiral rollers 1 are arranged on either side of the data transmission platform 4 via a bracket and are controlled and connected by the drive unit, allowing the device to move forward or backward freely in a full water drainage pipe. The shape and structure of the spiral rollers enable them to automatically adapt to the water pressure and resistance within the pipe as it flows. Through rolling and friction, they propel the device through the water flow. This not only ensures that the camera can be smoothly advanced in environments with different water levels, but also automatically adjusts its direction when encountering obstacles, ensuring stable operation of the camera in complex pipe environments.

[0035] The shooting mechanism includes a high-definition camera 7, which is set above the data transmission platform 4 through a lifting bracket 3 using a closed-circuit television (CCTV). The lifting bracket 3 transmits data to the database telecommunications connection through a PLC control system, which is used to longitudinally adjust the shooting range of the high-definition camera 7 to adapt to different shooting requirements and specific conditions in the pipeline, ensuring that a wider shooting area can be covered.

[0036] Furthermore, in this embodiment, the lifting bracket 3 is rotatably connected to the high-definition camera 7 through a rotating shaft mechanism, and the rotating shaft mechanism is connected to the telecommunications system for transmitting data to the database through the PLC control system, and is used to control the rotating shaft mechanism to adjust the shooting angle of the high-definition camera 7 360°, flexibly changing the shooting angle, thereby avoiding dead angles and blind spots, and providing an all-round monitoring perspective.

[0037] The airbag mechanism is arranged on both sides of the shooting mechanism, including transparent airbags 6 respectively arranged on both sides of the high-definition camera 7. The transparent airbags 6 are connected to an external air source through the trachea 2, and the air source inflates the transparent airbags 6 on both sides of the high-definition camera 7 through the trachea 2. The inflated transparent airbags 6 can be tightly attached to the inner wall of the pipeline, thereby fixing the position of the high-definition camera 7, providing a stable shooting environment for the high-definition camera 7, and at the same time effectively preventing the camera from being offset due to pipeline vibration or water flow impact, thereby ensuring the stability and clarity of the captured image.

[0038] Furthermore, in this embodiment, a fill light 5 is provided at the bottom of the HD camera 7, enabling the camera to clearly capture details inside the pipe even in low-light or dark environments, preventing blurry or unclear images caused by insufficient light. This design enhances the camera's adaptability in complex and dim environments, ensuring high-quality image data in all circumstances.

[0039] The utility model also provides a workflow of the underwater video detection device, which is as follows:

[0040] The utility model is placed in a pipe. The spiral drum 1 is used to freely move forward and backward in the drainage pipe full of water. The high-definition camera 7 performs an initial inspection. The high-definition camera 7 sends the video or photos taken by the high-definition camera 7 to the database through the data transmission pan-tilt head 4 through the PLC control system. The database performs comparison and diagnosis based on the model and provides real-time feedback.

[0041] When the database preliminarily screens out suspected disease points, the high-definition camera 7 of the present invention is used to adjust the angle through the rotating shaft mechanism and the lifting bracket to make it closer to the diseased part of the pipe wall, and then the trachea 2 is inflated by an external air source to make the transparent airbag 6 tightly fit the two sides of the pipe wall disease after expansion. In this way, the high-definition camera 7 can fix the position to be photographed, and then shoot through the high-definition camera 7. The video or photo taken is converted into image data through the data transmission pan-tilt head 4 and sent to the database through the PLC control system, and then the image data is evaluated based on the disease model in the database.

[0042] In summary, the present invention uses a spiral drum to move freely in a drainage pipe full of water, uses a high-definition camera for initial inspection, and sends the captured image data to the database through a PLC control system for disease diagnosis and comparison. The system can provide real-time feedback on suspected disease points, and uses a rotating shaft mechanism and a lifting bracket to adjust the camera angle to ensure accurate shooting; the expansion and fixing function of the transparent airbag ensures that the camera is firmly fixed on the diseased area for detailed shooting. The image data is evaluated through the disease model in the database, which improves the accuracy and efficiency of pipeline inspections. This design integrates real-time monitoring, accurate diagnosis and flexible adjustment, greatly improving the intelligence level and automation capabilities of pipeline inspections, reducing manual intervention, improving the intelligence and accuracy of the inspection process, and enhancing the reliability of pipeline maintenance.
