A gas pipeline safety inspection device based on unmanned aerial vehicles (UAVs)

Abstract

This utility model relates to the field of drone inspection technology and discloses a gas pipeline safety inspection device based on a drone, including a flight component. The outer wall of the flight component is provided with a lower detection and shooting component. In daily use, the flight component can be controlled to take off and fly. The lower and upper detection and shooting components can effectively inspect the gas pipeline to find damage. When the transparent acrylic cover loses the limiting force of the fixed limiting plate, it will rotate at a certain angle due to the setting of the counterweight, so that the transparent acrylic cover with bird droppings will not obstruct the normal monitoring and shooting of the camera component. After the reciprocating threaded rod continues to rotate, the fixed limiting plate and the compression pad will reset, and finally the compression pad can press the rotated and lying transparent acrylic cover firmly, ensuring that the camera component is not blocked by bird droppings.

Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) inspection technology, specifically a gas pipeline safety inspection device based on UAVs. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices. They are characterized by high timeliness, good maneuverability, wide patrol range, and wide range of applications. In the field of environmental protection, they are mainly used for environmental monitoring, such as UAV water quality monitoring and UAV air monitoring. Traditional environmental monitoring usually uses point monitoring to estimate the environmental quality of the entire area, which has certain limitations and biases. UAV environmental monitoring systems have the characteristics of wide field of view, timeliness, and continuity, and can quickly ascertain the current environmental status.

[0003] According to a public notice regarding a drone that is easy to carry monitoring equipment (Announcement No.: CN221024200U), the above application uses mounting plates above and below the drone to install image acquisition equipment on both sides, thus solving the problem of blind spots in the drone's upper field of view. Furthermore, the electric telescopic pole extends and retracts to move the mounting plates, allowing the equipment to be retracted into the limiting frame for protection when not in use, effectively preventing collisions that could easily occur during landing.

[0004] However, in actual use, the above-mentioned equipment may be affected by bird droppings falling during the use of drones and image acquisition devices, resulting in the inability of the image acquisition devices to take pictures normally; in view of this, we propose a gas pipeline safety detection device based on drones. Utility Model Content

[0005] The purpose of this invention is to provide a gas pipeline safety inspection device based on unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas pipeline safety detection device based on a drone, comprising a flight component, a lower detection and imaging component disposed on the outer wall of the flight component, an upper detection and imaging component disposed on the outer wall of the flight component, the upper detection and imaging component comprising a mounting plate, the mounting plate being fixedly connected to the outer wall of the flight component, a mounting frame being fixedly connected to the outer wall of the mounting plate, a protective sleeve being fixedly connected to the outer wall of the mounting frame, a motor being fixedly connected to the outer wall of the mounting frame, a reciprocating threaded rod being fixedly connected to the output end of the motor through the mounting frame, a threaded slider being threadedly connected to the outer wall of the reciprocating threaded rod, and a transmission plate being fixedly connected to the outer wall of the threaded slider;

[0007] A fixed limiting plate is fixedly connected to the end of the transmission plate. An extrusion pad is fixedly connected to the outer wall of the fixed limiting plate. A protective shell is fixedly connected to the outer wall of the mounting plate. A transparent plate is fixedly connected to the outer wall of the protective shell. A hinge sleeve is fixedly connected to the outer wall of the protective shell. A transparent acrylic shield is hinged to the outer wall of the hinge sleeve. A counterweight is fixedly connected to the outer wall of the transparent acrylic shield. A camera assembly is provided on the outer wall of the mounting plate.

[0008] Preferably, the number of counterweights is two sets, and the two sets of counterweights are mirror images of the center plane of the transparent acrylic shield on both sides.

[0009] Preferably, the outer wall of the threaded slider is adapted to the inner wall of the sheath, so that the threaded slider can move smoothly.

[0010] Preferably, the centerline of the reciprocating threaded rod and the centerline of the transmission plate are both in the same plane.

[0011] Preferably, the outer wall of the protective shell is provided with a secondary protection component, the secondary protection component including a limiting top plate, the limiting top plate being fixedly connected to the outer wall of the protective shell, and a transparent acrylic shield second being slidably connected to the inner wall of the protective shell, the end of the transparent acrylic shield second being fixedly connected to a movable baffle.

[0012] Preferably, the outer wall of the movable baffle is adapted to the inner wall of the protective shell, so that the movable baffle can move smoothly.

[0013] Preferably, the center line of the limiting top plate and the center line of the movable baffle are on the same straight line.

[0014] Compared with the prior art, this utility model provides a gas pipeline safety detection device based on drones, which has the following beneficial effects:

[0015] 1. This drone-based gas pipeline safety inspection device, during daily use, can be operated to take off and fly. The lower and upper detection and imaging components can effectively inspect the gas pipeline to detect damage. When bird droppings obstruct the transparent acrylic cover, the motor can be activated to rotate the reciprocating threaded rod, causing the limited threaded slider to move forward, gradually disengaging the fixed limiting plate from the transparent acrylic cover. When the transparent acrylic cover loses the limiting force of the fixed limiting plate, it will rotate at a certain angle due to the counterweight, ensuring that the transparent acrylic cover with bird droppings does not obstruct the normal monitoring and imaging of the camera component. As the reciprocating threaded rod continues to rotate, the fixed limiting plate and the compression pad will reset, ultimately allowing the compression pad to compact the rotated and lying transparent acrylic cover, ensuring that the camera component is not obstructed by bird droppings.

[0016] 2. In this UAV-based gas pipeline safety inspection device, when the transparent acrylic shield 1 loses the limiting force of the fixed limiting plate and rotates, the transparent acrylic shield 2 and the moving baffle will move downward, so that the transparent acrylic shield 2 can continue to protect the transparent plate and prevent bird droppings from blocking the camera components, while further improving the overall practicality.

[0025] like Figures 1-7 As shown, this utility model provides a technical solution: a gas pipeline safety detection device based on a drone, including a flight component 1, a lower detection and imaging component 2 and an upper detection and imaging component 3 on the outer wall of the flight component 1, the upper detection and imaging component 3 including a mounting plate 301, the mounting plate 301 being fixedly connected to the outer wall of the flight component 1, a mounting frame 302 being fixedly connected to the outer wall of the mounting plate 301, a protective sleeve 303 being fixedly connected to the outer wall of the mounting frame 302, a motor 304 being fixedly connected to the outer wall of the mounting frame 302, a reciprocating threaded rod 305 being fixedly connected to the output end of the motor 304 through the mounting frame 302, a threaded slider 306 being threadedly connected to the outer wall of the reciprocating threaded rod 305, and a transmission plate 307 being fixedly connected to the outer wall of the threaded slider 306.

[0026] Furthermore, the fixed limiting plate 308 is fixedly connected to the end of the transmission plate 307, and the outer wall of the fixed limiting plate 308 is fixedly connected to the extrusion pad 309. The outer wall of the mounting plate 301 is fixedly connected to the protective shell 313, the outer wall of the protective shell 313 is fixedly connected to the transparent plate 314, the outer wall of the protective shell 313 is fixedly connected to the hinge sleeve 310, the outer wall of the hinge sleeve 310 is hinged to the transparent acrylic cover plate 312, the outer wall of the transparent acrylic cover plate 312 is fixedly connected to the counterweight block 311, and the outer wall of the mounting plate 301 is provided with a camera assembly 5.

[0027] In the embodiments of this utility model, the number of counterweights 311 is two sets, and the two sets of counterweights 311 are mirror images of the center plane of the transparent acrylic shield 312 on both sides. The outer wall of the threaded slider 306 is adapted to the inner wall of the sheath 303, so that the threaded slider 306 can move smoothly. The center line of the reciprocating threaded rod 305 and the center line of the transmission plate 307 are both in the same plane.

[0028] Furthermore, the outer wall of the protective shell 313 is provided with a secondary protection component 4. The secondary protection component 4 includes a limiting top plate 401, which is fixedly connected to the outer wall of the protective shell 313. A transparent acrylic shield 402 is slidably connected to the inner wall of the protective shell 313. A movable baffle 403 is fixedly connected to the end of the transparent acrylic shield 402. The outer wall of the movable baffle 403 is adapted to the inner wall of the protective shell 313, so that the movable baffle 403 can move smoothly. The center line of the limiting top plate 401 and the center line of the movable baffle 403 are on the same straight line.

[0029] In this invention, during daily use, the flight component 1 can be controlled for flight. The lower detection and imaging component 2 and the upper detection and imaging component 3 can effectively inspect the gas pipeline to detect damage. When bird droppings obscure the transparent acrylic cover 312, the motor 304 can be activated to rotate the reciprocating threaded rod 305, causing the limited threaded slider 306 to move the transmission plate 307 forward. This allows the fixed limiting plate 308 to gradually detach from the transparent acrylic cover 312. When the transparent acrylic cover 312 loses the limiting force of the fixed limiting plate 308, it will rotate at a certain angle due to the setting of the counterweight 311, so that the transparent acrylic cover 312 with bird droppings will not obstruct the normal monitoring and shooting of the camera component 5. After the reciprocating threaded rod 305 continues to rotate, the fixed limiting plate 308 and the compression pad 309 will be reset, and finally the compression pad 309 can press the rotated and lying transparent acrylic cover 312 firmly, ensuring that the camera component 5 will not be blocked by bird droppings.

[0030] When the transparent acrylic cover 312 loses the limiting force of the fixed limiting plate 308 and rotates, the transparent acrylic cover 402 and the movable baffle 403 will move downward, so that the transparent acrylic cover 402 can continue to protect the transparent plate 314 and prevent bird droppings from blocking the camera component 5, while further improving the overall practicality.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
