Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, specifically a pipeline wind-driven inspection vessel. Background Technology

[0002] CCTV inspection of pipelines, introduced to China in the mid-1990s for the inspection of internal pipeline conditions and the health of drainage systems, is the most advanced and effective method for pipeline condition inspection internationally. Developed countries and regions in Europe and America use this method for drainage pipeline health checks. CCTV inspection employs an advanced CCTV endoscopic television inspection system that automatically crawls inside the pipeline to detect and image conditions such as rust, scale corrosion, perforations, and cracks.

[0003] Currently available pipeline inspection robots have some drawbacks, such as the inability of "all-terrain pipeline inspection robots" to enter pipelines smaller than DN500 for inspection, and the inability of "CCTV pipeline inspection robots" to inspect pipelines containing water or silt. Therefore, a small, wind-powered pipeline inspection vessel was invented to compensate for the shortcomings of poor flexibility and large size of inspection equipment, which are not suitable for inspecting small pipelines. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pipeline wind-driven inspection vessel, which has the advantages of small size, flexibility, shallow draft, and convenient operation, and can be used for the inspection of small-sized pipelines. It solves the problems of large size, unsuitability for pipeline inspection below DN500, poor flexibility, and pipeline obstacle avoidance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipeline pneumatic inspection vessel, comprising a hull and a metal frame, wherein a ducted motor 1 is fixedly installed near the top of the stern of the hull, and ducted motors 2 are fixedly installed on both sides of the top of the bow of the hull, and a fixed support is fixedly installed on the top of the bow of the hull between the two ducted motors 2, a lighting lamp is fixedly installed on the top of the fixed support, and an infrared camera is provided in front of the fixed support.

A hand crank connected to the winding roller is provided on the front of the winding frame. An L-shaped post is fixedly installed on the top of the metal frame, and a guide rope wheel is movably installed at the bottom of the crossbar of the L-shaped post. A vertical post is also fixedly installed on the top of the metal frame, and a rope wheel arm is provided on the front of the vertical post. A rope wheel is rotatably installed on the front of the rope wheel arm via a bearing. A meter counter is provided on the top of the metal frame.

[0008] Furthermore, the L-shaped pile is arranged side by side with the upright pile, and the guide rope wheel is located on top of the rope wheel, with a gap between the guide rope wheel and the rope wheel allowing the rope to pass through the middle.

[0009] Furthermore, a start button and a control switch are provided on the top of the hull, and both the control switch and the start button are electrically connected to the control module via CNC transmission cables.

[0010] Furthermore, the take-up roller is wound with a rope, and the rope passes through the gap between the guide sheave and the rope sheave and is connected to the stern of the hull.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] This pipeline wind-powered inspection vessel uses a ducted motor to provide forward propulsion, and two ducted motors for steering to achieve obstacle avoidance within the pipeline.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2 This embodiment of a pipeline wind-driven inspection vessel includes a hull 1 and a metal frame 2. The hull 1 is equipped with a power battery, a control module, and a numerical control transmission cable electrically connected to a duct motor 5, a duct motor 6, a lighting lamp 7, and an infrared camera 8. A duct motor 5 is fixedly installed near the top of the stern of the hull 1. Duct motors 6 are fixedly installed on both sides of the top of the bow of the hull 1. A fixed support 9 is fixedly installed on the top of the bow of the hull 1, between the two duct motors 6. A lighting lamp 7 is fixedly installed on the top of the fixed support 9. An infrared camera 8 is located in front of the fixed support 9.

[0018] It should be noted that the CNC transmission cable uses cable connection to control and transmit data for each motor, light, and camera. The cable is a high tensile strength ROV zero buoyancy 4-core cable with a diameter of 6mm. Duct motor 15 provides forward power for the 50-type duct motor, and duct motor 26 provides steering power for the 30-type duct motor.

[0019] 1. The parameters of the 50 ducted motor are as follows:

[0020] Maximum voltage 16.8V, maximum current 40A, maximum thrust 950g, full load power 670W, duct weight 77g.

[0021] 2. The parameters of the 30 ducted motor are as follows:

[0022] Maximum voltage 14.8V, maximum current 20A, maximum thrust 265g, full load power 160W, duct weight 21.8g.

[0023] In this embodiment, a winding frame 11 is fixedly installed on one side of the top of the metal frame 2. A winding roller 12 is movably installed in the middle of the winding frame 11 via a bearing. A hand crank 13 connected to the winding roller 12 is provided on the front of the winding frame 11. An L-shaped post 10 is fixedly installed on the top of the metal frame 2. A guide rope wheel 17 is movably installed at the bottom of the crossbar of the L-shaped post 10. A vertical post 14 is also fixedly installed on the top of the metal frame 2. The L-shaped post 10 and the vertical post 14 are arranged side by side. A rope wheel arm 15 is provided on the front of the vertical post 14. A rope wheel 16 is rotatably provided on the front of the rope wheel arm 15 via a bearing. The guide rope wheel 17 is located on top of the rope wheel 16. The gap between the guide rope wheel 17 and the rope wheel 16 allows the rope to pass through the middle. A meter counter 18 is provided on the top of the metal frame 2.

[0024] It should be noted that the meter counter 18 uses a photoelectric sensor to convert light signals into electrical signals to calculate the length of the cable. The error can be controlled within 1 cm, ensuring that the distance of the defect is confirmed during the inspection and meeting the defect location standard for pipeline inspection.

[0025] In this embodiment, a start button 3 and a control switch 4 are provided on the top of the hull 1. Both the control switch 4 and the start button 3 are electrically connected to the control module through a CNC transmission cable.

[0026] It should be noted that the operator can control the hull 1 through the terminal controller. The terminal controller uses a 10-inch industrial control computer tablet to control the hull and record video transmission. This terminal uses a WIN10 system and is self-powered for 5 hours of operation. The control terminal uses a self-developed control program to control the wind-powered boat and record data transmission.

[0027] In this embodiment, the take-up roller 12 is wound with a rope, and the rope passes through the gap between the guide rope wheel 17 and the rope wheel 16 and is connected to the stern of the hull 1.

[0028] The working principle of the above embodiments is as follows:

[0029] When an inspection vessel is needed to inspect the inside of a pipeline, the rope is first wound around the take-up roller 12 of the take-up frame 11. Simultaneously, one end of the rope is passed through the gap between the guide rope pulley 17 and the rope pulley 16 between the L-shaped pile 10 and the upright pile 14, and secured to the stern of the vessel 1 with a rope buckle. After connecting the vessel 1 to the metal frame 2, the metal frame 2 is placed on the road surface near the pipeline opening. Then, the start button 3 and control switch 4 on the top of the vessel 1 are turned on, and the vessel 1 is lowered into the water inside the pipeline using a lifting device. Once the vessel 1 is in place, the duct motor 5 can be started via the terminal controller to generate... Wind power propels the hull 1 forward on the water surface of the pipeline. When the hull 1 needs to turn, one of the two ducted motors 6 can be controlled to push the bow of the hull 1 in the desired direction to achieve the turning function. At the same time, the fixed support 9 and the lighting 7 on the hull 1 can be turned on to illuminate the surrounding environment inside the pipeline. Finally, an infrared camera 8 is used to accurately photograph, capture defects and dynamically monitor the internal structure of the pipeline. The captured images are then displayed on the operator's terminal controller screen via a digital transmission cable for observation.
