Description

Technical Field

[0001] This application relates to the field of inspection drones, and in particular to a railway multi-rotor drone inspection device. Background Technology

[0002] Railway multi-rotor drones are special-purpose drones designed for railway inspection, security, and other tasks. They feature vertical take-off and landing, flexible hovering, and simple structure, enabling them to efficiently complete tasks such as railway infrastructure inspection, line safety monitoring, and emergency response. With the development of technologies such as AI obstacle avoidance and 5G remote control, their operational accuracy and safety are continuously improving. Supported by policies, they are driving intelligent railway management. When using conventional inspection drones, after placing the drone in a suitable location, the drone starts up and controls the top rotor blades to rotate at high speed, controlling the drone to move around the railway. The recording mechanism inside the drone saves the footage, facilitating long-distance and high-altitude inspections by staff. A support frame is fixedly connected to the bottom of the drone, allowing it to be parked when landing.

[0003] Regarding the aforementioned technologies, the inventors believe that inspection drones often need to be launched regularly for inspections. The conventional method of placing and retrieving them manually consumes a lot of time and energy from the staff. Furthermore, when inspecting locations far from the station, more time is required for the journey to the destination, thus causing inconvenience when using inspection drones.

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0017] This application discloses a railway multi-rotor unmanned aerial vehicle (UAV) inspection device, referring to... Figure 1 - Figure 2The system includes the drone itself. When in use, after placing the drone in a suitable location, the drone starts and controls the top rotating blades to rotate at high speed, controlling the drone to move around the railway. The recording mechanism inside the drone saves the footage, facilitating long-distance and high-altitude inspections by staff. A support frame is fixedly connected to the bottom of the drone, allowing it to land safely. The mounting frame is attached to the surface of utility poles around the railway. A charging base is fixedly connected to the top of the mounting frame, and a cover is rotatably connected to the top of the charging base to protect against rain and snow. A placement plate is slidably mounted on the top of the mounting frame, and its top is movably connected to the bottom of the support frame. The drone can be installed in different locations and charged via the charging base. When in use, the cover is opened, and the drone can be flown around the area. This significantly improves the convenience of using the inspection drone, eliminating the need for staff to place and retrieve the drone during inspections.

[0018] Reference Figure 2 A wireless charger is fixedly installed on the surface of the drone body. One end of the wireless charger is movably connected to a charging connector, and the other end of the charging connector is fixedly installed on the surface of the charging base. The wireless charger and charging connector facilitate the connection between the drone body and the charging base, thereby enabling the wireless charging function of the drone body and ensuring the power supply of the drone body when placed in the outside. Several retaining rings are rotatably connected to the top of the placement plate. A limit frame is rotatably installed on the surface of the retaining rings. One end of the limit frame is rotatably connected to a first electric push rod. One end of the first electric push rod is rotatably installed on the inner wall of the placement plate. After adjusting its own length, the first electric push rod controls the retaining rings to rotate with the limit frame, thereby fixing the drone body with retaining rings when the support frame contacts the placement plate, preventing the drone body from loosening after landing on the surface of the placement plate. A laser guide is fixedly installed on the top of the placement plate. The laser guide emits a laser to achieve precise landing of the drone body when it returns to home.

[0019] Reference Figure 2 - Figure 4A second electric push rod is installed at both ends of the cover. One end of the second electric push rod is rotatably connected to the surface of the charging base. By adjusting its length, the second electric push rod controls the opening and closing of the cover, thus controlling the cover to shield the surface of the charging base when the drone takes off and lands. Two sliding frames are fixedly connected to the top of the mounting frame. The surfaces of the sliding frames are slidably installed against the inner wall of the placement plate, and one end of the sliding frame is fixedly connected to a limit plate to prevent the placement plate from detaching from the sliding frame. The sliding frames facilitate the movement of the placement plate, thereby moving the drone into the charging base. When the drone takes off, the placement plate is removed from the charging base, avoiding the problem of limited space in the charging base causing difficulties in takeoff and landing of the drone. A third electric push rod is fixedly connected to one end of the placement plate. The surface of the third electric push rod is fixedly connected to the inside of the charging base. By adjusting its length, the third electric push rod controls the movement of the placement plate, effectively reducing the amount of manual operation.

[0020] The implementation principle of the railway multi-rotor drone inspection device in this application embodiment is as follows: A charging base is fixedly connected to the top of the mounting frame and the surface of utility poles around the railway. A cover is rotatably connected to the top of the charging base to shield against rain and snow. A placement plate is slidably mounted on the top of the mounting frame, and the top of the placement plate is movably connected to the bottom of the support frame, allowing the drone to be installed in different positions. The drone is charged via the charging base. During use, the cover is opened to allow the drone to fly around the area, thus avoiding the need for personnel to place and retrieve the drone during inspection. A wireless charger is fixedly mounted on the surface of the drone, with a charging connector movably connected to one end. One end of the charging connector is fixedly mounted to the surface of the charging base. To facilitate easy connection of the drone to the charging base using a wireless charger and charging connector, enabling wireless charging of the drone and ensuring power supply when placed outdoors, the top of the placement plate has several rotatable retaining rings. A limit frame is rotatably mounted on the surface of each retaining ring, with a first electric push rod rotatably connected to one end of the limit frame. One end of the first electric push rod is rotatably mounted to the inner wall of the placement plate. This allows the first electric push rod to adjust its length and then control the retaining rings to rotate using the limit frame. This secures the drone when it contacts the placement plate, preventing it from becoming loose after resting on the plate surface. A laser guide is fixedly mounted on the top of the placement plate to emit a laser, enabling precise stopping of the drone during its return journey.

[0021] A second electric push rod can be installed at both ends of the cover. One end of the second electric push rod is rotatably connected to the surface of the charging base, so that the cover can be opened and closed by adjusting its length. This allows the cover to block the surface of the charging base when the drone takes off and lands. Two sliding frames are fixedly connected to the top of the mounting frame. The surfaces of the sliding frames are slidably installed on the inner wall of the placement plate, and one end of the sliding frame is fixedly connected to a limit plate to prevent the placement plate from detaching from the sliding frame. This allows the placement plate to be moved easily by the sliding frame, thereby moving the drone into the charging base. When the drone takes off, the placement plate is removed from the charging base, avoiding the problem of limited space in the charging base causing difficulties in takeoff and landing of the drone. A third electric push rod is fixedly connected to one end of the placement plate. The surface of the third electric push rod is fixedly connected to the inside of the charging base, so that the placement plate can be moved by adjusting its length, effectively reducing the amount of manual operation.

[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
