Description

Technical Field

[0001] The utility model relates to the technical field of petroleum inspection, in particular to an oil leakage detection inspection device. Background Art

[0002] An oil pipeline is a pipeline system used to transport crude oil, natural gas, refined oil, etc. from oil and gas fields, refineries, storage depots, docks, etc. to users or receiving stations. Since crude oil exists in the form of oil, gas, water and formation particles during the extraction process, the properties and flow states of these substances will corrode the pipeline, which may cause pipeline leakage.

[0003] Therefore, oil pipeline inspection is one of the important measures to ensure the safe and stable operation of pipelines. Currently, most inspections are carried out manually, but manual inspections usually rely on inspectors walking or driving. For long-distance and complex oil pipeline networks, this method has relatively low inspection efficiency and it is difficult to complete a comprehensive inspection in a short time. Utility Model Content

[0011] Furthermore, the rack 2 is symmetrically located on both sides of the power gear, the rack 2 cooperates with the power gear, and one rack 2 and one rack 1 are fixedly connected.

[0012] The advantages of the utility model are:

The rectangular hole 3 is set to enable the extension rod 6 to rotate in the rectangular hole 3.

[0024] Vertical mounting shafts 4 are provided near the four corners of the rectangular hole 3 , and matching gears 5 are provided on the mounting shafts 4 . The rotation of the matching gears 5 can drive the extension rods 6 to rotate, so that the propeller components 7 can be brought closer to each other.

[0025] An outwardly inclined extension rod 6 is provided on the outer wall of the mating gear 5, and the extension rod 6 is fixedly connected to the outer wall of the mating gear 5. A propeller component 7 is provided at the end of the extension rod 6. The propeller component 7 is connected to the power system of the aircraft, and the power system is installed in the power box 16, thereby driving the propeller component to rotate and enabling the flying body 1 to fly.

[0026] A notch 8 is provided on the mating gear 5, and a movably fitted positioning column 9 is provided on one side of the notch 8. A power component is provided between the two mating gears 5, and the power component drives the mating gear 5 to rotate. After the power component drives the mating gear 5 to rotate until the two extension rods 6 are parallel to each other, the other side of the notch 8 is movably fitted with the positioning column 9.

[0027] The bottom of the flying body 1 is symmetrically provided with protective plates 10 , and the two protective plates 10 are located on both sides of the camera 2 . The protective plates 10 can prevent the camera 2 from being hit during the flight, thereby improving the safety of the camera 2 .

[0028] The gear teeth on the matching gear 5 are located between the notch 8 and the extension rod 6 , and the bottom of the positioning column 9 is fixedly connected in the flying body 1 .

[0029] The power assembly includes a rack 11, a rack 2 12, a power gear 13, a power shaft 14 and a motor 15. The rack 11 is symmetrically arranged between two adjacent mating gears 5. The two sides of the rack 11 have spaced apart gear teeth, which are respectively meshed with the gear teeth on the mating gears 5. Through the arrangement of the rack 11, when the rack 11 moves in one direction, it drives the two mating gears 5, one to rotate counterclockwise and the other to rotate clockwise.

[0030] The power shaft 14 is vertically installed at the inner center position of the flight body 1, the power gear 13 is installed on the power shaft 14, a power box 16 is provided on the top of the flight body 1, a motor 15 is installed in the power box 16, and the output shaft of the motor 15 is connected to the power shaft 14. Through the connection of the motor 15, the power gear 13 is driven to rotate.

[0031] The rack 2 12 is symmetrically located on both sides of the power gear 13, and the rack 2 12 cooperates with the power gear 13, and one rack 2 12 and one rack 1 11 are fixedly connected, so that when the rack 2 12 moves, the rack 1 11 will be driven to move.

[0032] Detailed usage and effects of the above embodiments:

[0033] When it is necessary to inspect the oil pipeline, the aircraft is started to rotate the propeller component 7, driving the aircraft body 1 to fly, and the camera 2 at the bottom of the aircraft body 1 will take pictures. The shooting position of the camera 2 is adjusted by controlling the aircraft to inspect the oil pipeline. In the initial state, the rack 11 is fixedly connected between the two matching gears 5. At this time, the positioning column 9 is just in contact with the notch 8 on one side of the matching gear 5. With the cooperation of the positioning column 9 and the rack 11, it is ensured that the matching gear 5 will not rotate, so that the extension rod 6 remains stationary.

[0034] When a smaller space is needed for an oil pipeline, the motor 15 is started. The motor 15 drives the power gear 13 to rotate through the power shaft 14. When the power gear 13 rotates, the position of the rack 2 12 matched therewith changes, so that the overlapping area of ​​the two racks 2 12 becomes larger and larger, and the two racks 1 11 are close to each other, thereby driving the rotating gear on the single rack 1 11 to rotate, and the two extension rods 6 are close to each other. When the two extension rods 6 rotate to be parallel to each other, they will be blocked by the positioning column 9 and will no longer rotate. The power gear 13 will also stop rotating, thereby reducing the body of the aircraft. In a special space, better oil pipeline inspection can be carried out by reducing the width of the overall fuselage.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
