Description

Technical Field

[0001] The utility model relates to unmanned aerial vehicle inspection technology, in particular to an unmanned aerial vehicle pipeline inspection device. Background Art

[0002] At present, in order to ensure the safe transportation of gas, the gas pipelines and equipment in the city need to be inspected once every 5 days during use. However, the existing inspection methods are mostly manual inspection methods, which require a lot of manpower and material resources to barely complete the inspection tasks, and the inspection results are not very ideal.

[0003] After searching, the authorization announcement number CN218086035U discloses an inspection drone, which specifically discloses: including a drone body, a camera, a gas detection device, a laser ranging device and a controller; wherein the first support device includes a mounting bracket, a first steering gear, a vertical bracket, a second steering gear, a U-shaped bracket, a third steering gear and a support plate; through the inspection drone of this application, it can fly to the corresponding position of the pipeline, and then collect images of the pipeline and monitoring instruments through the camera, and detect whether the combustible gas near the pipeline exceeds the standard through the gas detection device, thereby replacing manual inspection work to improve inspection efficiency. However, this existing technology cannot mark the pipeline with problems, which is not convenient for subsequent maintenance.

[0004] Authorization announcement number CN219120358U discloses a pipeline inspection drone, specifically including: a drone body equipped with a GPS positioning module, a rotatable camera, a gas detection device and a marking device, and a controller installed inside the drone body. This prior art replaces the manual inspection method, thereby saving the time of manual inspection along the gas pipeline, improving work efficiency, and avoiding the potential safety hazards of line inspectors during mountain inspections, thereby ensuring personal safety. However, when the pipeline inspection drone is in use, due to the small size of the gas pipeline, the dripping method makes it easy for the marking liquid to not drip accurately on the gas pipeline, reducing the marking effect.

The support frame 12 is installed at both ends of the bottom surface of the support plate 6 by bolts, and the buffer pad 13 is bonded to the bottom surface of the support frame 12.

[0033] like Figure 3As shown, the marking assembly 3 is installed in the middle of the top wall of the mounting frame 2, including a liquid storage bottle 31, a solenoid valve 32, a first connecting pipe 33, a micro high-pressure pump 34, a second connecting pipe 35, an atomizing nozzle 36 and an elastic buckle 14; the liquid storage bottle 31 is threadedly connected to the middle of the top wall of the mounting frame 2, the solenoid valve 32 is threadedly connected to the bottom surface of the liquid storage bottle 31, the first connecting pipe 33 is threadedly connected to the bottom surface of the solenoid valve 32, the first connecting pipe 33 is threadedly connected to the micro high-pressure pump 34 at one end away from the solenoid valve 32, the micro high-pressure pump 34 is installed at the rear end of the inner surface of the mounting frame 2 by bolts, the second connecting pipe 35 is threadedly connected to the rear side of the micro high-pressure pump 34, the atomizing nozzle 36 is threadedly connected to the end of the second connecting pipe 35 away from the micro high-pressure pump 34, the atomizing nozzle 36 faces the pipeline and is located directly above the pipeline clamped by the clamping assembly 8, the elastic buckle 14 is clamped with the end of the second connecting pipe 35 close to the atomizing nozzle 36, and is installed in the middle of the left bottom surface of the mounting frame 2 by bolts.

[0034] The gas detection module 4 is installed on the front end of the inner surface of the mounting frame 2 by means of bolts to detect whether there is natural gas near the pipeline.

[0035] There are two cylinders 7, which are respectively installed on the outer sides of the two support plates 6 by bolts, and the output ends thereof pass through the support plates 6 to the inner sides of the support plates 6 and are connected to the clamping assembly 8.

[0036] like Figure 4 As shown, the clamping assembly 8 has two sets of clamping jaws, which clamp on both sides of the pipe. The clamping jaws include a connecting plate 81, a buffer spring 82, a clamping block 83 and a slide bar 84. The connecting plate 81 is installed on the telescopic end of the cylinder 7 by bolts. One end of the two buffer springs 82 is welded to the side of the connecting plate 81 away from the cylinder 7, and the other end is welded to the clamping block 83. The two slide bars 84 are installed on the side of the clamping block 83 where the buffer spring 82 is welded by bolts. The buffer spring 82 is sleeved on the slide bar 84. The end of the slide bar 84 away from the clamping block 83 passes through the connecting plate 81 and is slidably connected to the connecting plate 81.

The staff controls the drone body 1 to descend until the gas pipeline is located between the clamping components 8; the staff controls the external control system to send a signal to the controller 11 through the wireless communication device 10 to start the cylinder 7, and the cylinder 7 drives the connecting plates 81 to approach each other, so that the clamping block 83 is clamped on the gas pipeline, thereby completing the positioning between the drone body 1 and the gas pipeline, which is convenient for subsequent marking work. The buffer spring 82 forms a buffer between the clamping block 83 and the connecting plate 81 to prevent the cylinder 7 from causing excessive squeezing of the gas pipeline; the solenoid valve 32 is started, and the marking liquid in the liquid storage bottle 31 flows into the micro high-pressure pump 34 through the first connecting pipe 33. The micro high-pressure pump 34 pressurizes the marking liquid and sprays it onto the surface of the gas pipeline through the atomizing nozzle 36, thereby avoiding the problem that the marking liquid easily falls to the ground in a dripping manner.
