Description

Technical Field

[0001] This utility model belongs to the field of pressure pipeline inspection technology, and relates to a drone, particularly a drone that can be used for pressure pipeline inspection. Background Technology

[0002] Pressure pipelines refer to all pipelines subjected to internal or external pressure, regardless of the medium contained within them. Pressure pipelines are a part of a larger pipeline system used to transport, distribute, mix, separate, discharge, meter, control, and stop fluid flow; they are assemblies composed of pipes, fittings, flanges, bolted connections, gaskets, valves, other components or pressure-bearing parts, and supports. Currently, drones are commonly used for inspection and maintenance to facilitate inspection and repair.

[0003] A search revealed a Chinese patent document disclosing a drone for boiler inspection [Application No.: CN202420445309.0; Publication No.: CN221874327U]. This drone for boiler inspection includes a drone body, a connecting part fixedly connected to the bottom of the drone body, a side anti-collision component located at the end of the connecting part away from the drone body, a support component fixedly connected to the bottom of the connecting part, a telescopic component that extends and retracts in the height direction located at the bottom of the support component, and a ground buffer component located at the bottom of the telescopic component. This invention incorporates an anti-collision component to protect the drone body; it also includes an X-shaped telescopic frame and a buffer component to prevent damage to the drone body during landing.

[0004] While the X-shaped telescopic frame and buffer assembly disclosed in the patent prevent damage to the drone body during landing, they cannot provide all-around protection for the drone.

[0005] A search revealed a Chinese patent document disclosing a remote sensing monitoring device for farmland ecology [Application No.: CN202122564665.3; Publication No.: CN216003097U]. It includes: a drone body (1) and a protective cover fixed to the drone body for protection; the protective cover is formed by two interlocking halves (2); each half includes a square frame mesh (3) and a π-shaped plate (4), the π-shaped plate being fixed to the square frame mesh by bolts; the π-shaped plate has strip holes (8), and four clamping bolts (7) are fixed to the strip holes, with each pair of clamping bolts forming a group pressing against the wing of the drone body. This utility model is used for remote sensing monitoring of farmland ecology.

[0006] Although the drone disclosed in the patent can provide all-around protection for the drone, its protective cover is made up of two interlocking halves and uses a square protective net, which has defects in terms of ease of use and even force distribution. Utility Model Content

[0007] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a drone that can be used for pressure pipeline inspection. The technical problem to be solved by this utility model is: how to achieve all-round protection for the drone while ensuring ease of use and uniform force distribution.

[0008] The objective of this utility model can be achieved through the following technical solutions: A drone for inspecting pressure pipelines is provided. The drone body has a detachable circular frame with slots on both the top and bottom sides. A large mesh cover is fixed in the slots. Fixed posts are fixed at both ends of the large mesh cover. Small mesh covers are rotatably connected to the fixed posts. A fixing mechanism is provided between the small mesh covers and the circular frame.

[0009] The working principle of this utility model is as follows: a circular frame is installed on the drone body, and by sliding two small net covers, the drone body is wrapped in a sphere made up of two large net covers and two small net covers, providing all-round protection for the drone body.

[0010] Both the large and small mesh covers are made of carbon fiber.

[0011] The above structure utilizes carbon fiber materials for both the large and small mesh covers. Carbon fiber is made from carbonized fibers that have undergone epoxy coating and graphite pressing. Its advantages include light weight and high tensile strength. Among all low-density synthetic handle materials, carbon fiber is perhaps the strongest, effectively enhancing the protection of the drone body and making both the large and small mesh covers more robust.

[0012] Two hollow rods are fixed on the main body of the drone, and two connecting rods are fixed on the circular frame. A threaded rod extending into the connecting rod is rotatably connected to the connecting rod, and an extension rod is threadedly connected to the threaded rod. The extension rod is inserted into the hollow rod.

[0013] Using the above structure, by installing the extension rod, first align the two connecting rods on the circular frame with the insertion interface of the hollow rod, and then drive the extension rod to move by rotating the threaded rod, so that the extension rod is inserted into the hollow rod, thus realizing the installation of the circular frame and facilitating the disassembly of the circular frame.

[0014] The inner wall of the large mesh cover is provided with a sliding groove, and the outer wall of the small mesh cover is fixed with a slider, and the sliding groove and the slider are slidably connected.

[0015] By adopting the above structure, and by installing sliders and opening grooves, it is possible to make the small mesh cover slide on the large mesh cover and limit the movement of the small mesh cover.

[0016] The fixing mechanism includes a fixing block fixed on a small mesh cover. The fixing block has a circular groove. The circular frame has two circular openings. A locking post is slidably connected to the circular opening. The circular frame and the locking post are connected by a tension spring. The locking post is inserted into the circular groove.

[0017] Using the above structure, by installing the locking pins and opening the circular groove, when the small mesh cover rotates to fit into the locking groove of the circular frame, the locking pins are pulled to insert them into the circular groove of the small mesh cover, thus realizing the installation and fixation of the small mesh cover.

[0018] Compared with existing technologies, drones that can be used for pressure pipeline inspection have the following advantages: 1. Install the circular frame onto the drone body. By sliding the two small mesh covers, the drone body is wrapped in a sphere formed by two large mesh covers and two small mesh covers, providing all-round protection for the drone body.

[0019] 2. By installing the extension rod, first align the two connecting rods on the round frame with the insertion interface of the hollow rod. By rotating the threaded rod, the extension rod is driven to move, so that the extension rod is inserted into the hollow rod, thus realizing the installation of the round frame and facilitating the disassembly of the round frame.

[0028] Both the large mesh cover 4 and the small mesh cover 6 are made of carbon fiber.

[0029] The above structure utilizes carbon fiber materials for both the large mesh cover 4 and the small mesh cover 6. Carbon fiber is made from carbonized fibers that have undergone epoxy coating and graphite pressing. Its advantages include light weight and high tensile strength. Among low-density synthetic handle materials, carbon fiber is perhaps the strongest, thus enhancing the protection of the drone body 1 and making the large mesh cover 4 and small mesh cover 6 more robust.

[0030] Two hollow rods 8 are fixed on the main body 1 of the drone, and two connecting rods 9 are fixed on the circular frame 2. A threaded rod 10 extending into the connecting rod 9 is rotatably connected to the connecting rod 9. An extension rod 11 is threadedly connected to the threaded rod 10 and inserted into the hollow rod 8.

[0031] Using the above structure, by installing the extension rod 11, first align the two connecting rods 9 on the circular frame 2 with the insertion interface of the hollow rod 8, and drive the extension rod 11 to move by rotating the threaded rod 10, so that the extension rod 11 is inserted into the hollow rod 8, thereby realizing the installation of the circular frame 2 and facilitating the disassembly of the circular frame 2.

[0032] The inner wall of the large mesh cover 4 is provided with a sliding groove 12, and the outer wall of the small mesh cover 6 is fixed with a slider 13. The sliding groove 12 and the slider 13 are slidably connected.

[0033] By adopting the above structure, and by installing the slider 13 and opening the slide groove 12, it is possible to facilitate the sliding of the small mesh cover 6 on the large mesh cover 4, and to limit the movement of the small mesh cover 6.

[0034] The fixing mechanism includes a fixing block 14 fixed on the small mesh cover 6. The fixing block 14 has a circular groove 15. The circular frame 2 has two circular openings. The circular openings are slidably connected to the circular pins 16. The circular frame 2 and the pins 16 are connected by a tension spring 7. The pins 16 are inserted into the circular groove 15.

[0035] With the above structure, by installing the locking post 16 and opening the circular groove 15, when the small mesh cover 6 rotates to fit with the locking groove 3 of the circular frame 2, the locking post 16 is pulled to insert into the circular groove 15 of the small mesh cover 6, thus realizing the installation and fixation of the small mesh cover 6.

[0036] The working principle of this utility model is as follows: First, align the two connecting rods 9 on the circular frame 2 with the insertion interface of the hollow rod 8. By rotating the threaded rod 10, drive the extension rod 11 to move, so that the extension rod 11 is inserted into the hollow rod 8. By sliding the two small mesh covers 6, when the small mesh cover 6 rotates to fit with the slot 3 of the circular frame 2, pull the locking post 16 to insert the locking post 16 into the circular groove 15 of the small mesh cover 6, so that the drone body 1 is wrapped in the sphere spliced ​​by the two large mesh covers 4 and the two small mesh covers 6.

[0037] In summary, by using both large and small mesh covers, the drone can be protected in all directions.

[0038] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model.
