Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipeline detection, and specifically relates to an anti-rollover device for raft-type drainage pipeline detection equipment, which is mainly aimed at the situation that during the process of detecting diseases of urban drainage pipelines with large pipe diameters, deep water levels and rapid water flows, the equipment is difficult to maintain a balanced state and is very likely to roll over when using ordinary raft-type drainage pipeline detection equipment for detection. Background Art
[0002] The pipeline closed-circuit television system (CCTV for short) is a detection technology that uses video equipment to enter the drainage pipes and transmit the image data to the control computer for data analysis in the form of closed-circuit television recording. The pipeline closed-circuit television detection system originated in the 1960s and is mainly used in the detection of urban drainage pipe systems. CCTV pipeline endoscope detection technology is still in its infancy in my country. With the continuous increase in the country's investment in urban drainage pipe facilities and the continuous enhancement of people's environmental awareness, the management and maintenance of urban drainage pipes will also receive due attention, and the management and maintenance of urban drainage pipes will receive due attention, and CCTV pipeline endoscope detection technology will also be widely developed.
[0003] Working principle of CCTV pipeline endoscopy detection technology: Through the camera robot to conduct full-process video inspection of the inside of the pipeline, the rust layer, scaling, corrosion, perforation, cracks and other conditions in the pipeline are detected and photographed, so as to achieve long-distance detection inside the pipeline, real-time observation and preservation of video data, and transmit the video to the ground. Professional inspection engineers interpret all image data, analyze and evaluate the status of the pipeline through professional knowledge and professional software, effectively identify the internal anti-corrosion quality, corrosion status and the exact location of the water pipeline and water gushing point, scientifically and comprehensively understand the status of the pipeline, compile a pipeline status report, and evaluate the operation quality and function of the drainage pipeline, so as to provide economical and effective detection methods for the fixed-point repair of the pipeline, the completion acceptance of the newly laid pipeline, the scheme design before the pipeline repair, the construction monitoring during the repair process, and the re-testing after the repair.
[0004] The working procedures of CCTV pipeline endoscopy inspection technology include: data collection, on-site investigation, work design, on-site inspection, data processing, and report preparation. In actual work, these procedures can be appropriately modified or supplemented according to the size of the project and specific requirements.
[0005] CCTV pipeline endoscope inspection technology image interpretation method. A key content of CCTV pipeline endoscope inspection technology is to interpret the image data information to determine whether there are defects inside the pipeline, the type, grade and quantity of defects.
[0006] For pipelines with large diameters, deep water levels, and rapid water flows, since existing crawling pipeline inspection equipment cannot extend the lens above the water surface and thus cannot conduct effective pipeline inspections, derivative raft-type pipeline inspection equipment is often used. This equipment can utilize the rapid water flow in the drainage pipeline as power. When in normal use, it can float on the water surface to expose the camera above the water surface, thereby collecting image information. However, due to the characteristics of large pipeline diameters, deep water levels, and rapid water flows, the raft-type pipeline inspection equipment is extremely prone to capsizing. In this case, the camera is submerged below the water surface, and the inspection task cannot continue. The equipment can only be pulled out by the cable, and after adjusting the equipment's entry posture into the water, the inspection is restarted, which greatly affects the pipeline inspection efficiency. Summary of the Invention
[0007] In view of the above problems existing in the prior art, the present utility model provides an anti-overturning device for a raft-type drainage pipeline inspection equipment, which can increase the balancing moment of the raft-type drainage pipeline inspection equipment and solve the problem of its tipping over during the inspection of pipelines with large diameters, deep water levels, and rapid water flows.
[0008] The present utility model is implemented by adopting the following technical solutions:
[0009] An anti-overturning device for a raft-type drainage pipeline inspection equipment includes air bags, telescopic rods, support rods, bolts, and hoop collars; two air bags are made of rigid plastic and are respectively connected to two telescopic rods through two hoop collars. The two ends of the telescopic rods are connected to the hoop collars by welding, and the two telescopic rods are connected by welding through four support rods.
[0010] Compared with the existing technology, the present utility model has the following advantages: It overcomes the problems that the raft-type pipeline inspection equipment is prone to capsizing, the lens is submerged by water, and inspection cannot be carried out in the pipeline environment with large diameters, deep water levels, and rapid water flows. The anti-overturning device can increase the balancing moment of the raft-type drainage pipeline inspection equipment, thereby effectively preventing the raft-type pipeline inspection equipment from rotating, tipping over, or even capsizing.
