Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an airborne pan / tilt platform for unmanned aerial vehicles. Background Art

[0002] The drone gimbal is a supporting device used by drones to install and fix mission payloads such as cameras. The current mainstream gimbal layout is to place the gimbal under the drone fuselage. With the development of drone technology and the continuous improvement of drone load capacity and stability, drones are no longer limited to aerial photography and surveillance. In the field of firefighting, based on the video and image acquisition capabilities of drones, drones are used to obtain fire conditions on high floors. At the same time, drones are used to send water pipes to high altitudes and spray water to extinguish fires, which has gradually become the first choice for firefighters.

[0003] In order to facilitate the storage of firefighting drones, the fixing mechanism for fixing the water pipe nozzle generally does not protrude significantly from the drone body. However, when the drone takes off and the wings of the drone are unfolded, if the water pipe nozzle does not protrude from the drone body, the water sprayed by the water pipe will affect the operation of the drone wings and further affect the flight of the drone. Therefore, a drone-mounted gimbal is proposed. Utility Model Content

[0027] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0028] Reference Figure 1 to Figure 2 The embodiment of the utility model provides a drone airborne gimbal, comprising a mounting plate 10, a tube 20, a telescopic mechanism 30 and a bottom supporting mechanism 40. The mounting plate 10 is provided with a plurality of first mounting holes 11 for threaded connection with the drone fuselage, that is, the drone airborne gimbal is installed on the drone through the mounting plate 10.

The function of the telescopic plate 31 is to hold up the telescopic tube 32 and drive the telescopic end of the telescopic tube 32 to extend and retract. The telescopic plate 31 is provided with a pipeline groove 37, and the telescopic tube 32 is disposed on the pipeline groove 37. The pipeline groove 37 plays a role of limiting the telescopic tube 32, thereby preventing the telescopic tube 32 from shaking in its radial direction.

The side plate 34 is fixedly connected to the telescopic plate 31, and the rack 35 is fixedly connected to the side plate 34. The mounting plate 10 is provided with a motor fixing seat 13, and the driving motor 33 is fixedly installed on the motor fixing seat 13. The output shaft of the driving motor 33 is provided with a gear 36, and the rack 35 is meshedly connected with the gear 36. When the water outlet (i.e., the water outlet end of the telescopic tube 32) needs to be extended, the output shaft of the driving motor 33 rotates to drive the gear 36 to rotate, and the rotation of the gear 36 drives the rack 35 to move, and the movement of the rack 35 drives the side plate 34 and the telescopic plate 31 to extend, thereby realizing the extension of the water outlet end of the telescopic tube 32 until it is extended to a desired position.

[0031] Optionally, a clamp ring 38 is provided on one end of the pipeline groove 37 away from the tube 20, and the water outlet end of the telescopic tube 32 is fixedly connected to one end of the telescopic plate 31 through the clamp ring 38. The telescopic tube 32 is a corrugated tube.

[0032] The bottom support mechanism 40 includes a support plate 41, and the support plate 41 is fixedly connected to the mounting plate 10 through a connecting column 42. A mounting seat 44 is provided at one end of the connecting column 42 away from the support plate 41, and a plurality of second mounting holes 45 are provided on the mounting seat 44, and the second mounting holes 45 correspond to some of the first mounting holes 11, so that the mounting seat 44 can be threadedly connected to the mounting plate 10. The telescopic plate 31 is provided on the support plate 41, and the telescopic plate 31 is slidably connected to the support plate 41. The function of the support plate 41 is to support the telescopic plate 31, the side plate 34 and the rack 35. A protrusion 43 is provided on the support plate 41, and the cross section of the protrusion 43 is T-shaped, and a groove 391 corresponding to the protrusion 43 is provided on the lower end surface of the telescopic plate 31.

[0033] Optionally, limiting columns 392 are provided on both sides of the telescopic plate 31, and the limiting columns 392 are located between two connecting columns 42, and the height of the limiting columns 392 is greater than the distance between the side of the telescopic plate 31 and the connecting columns 42, so as to limit the telescopic plate 31 from being separated from the support plate 41 through the connecting columns 42, that is, the telescopic movement range of the telescopic plate 31 is equal to the distance between the two connecting columns 42 on the same side.

[0034] The utility model discloses a drone-mounted gimbal, and the specific implementation method is as follows: the drone-mounted gimbal is installed on the drone through the mounting plate 10, and the fire hose is connected to the water inlet of the tube 20. When the drone raises the water hose to a high altitude through the gimbal to spray water to extinguish the fire, the camera 12 obtains the real-time situation of the fire, the output shaft of the driving motor 33 rotates to drive the rotation of the gear 36, and the rotation of the gear 36 drives the movement of the rack 35. The movement of the rack 35 drives the side plate 34 and the telescopic plate 31 to extend, thereby realizing the extension of the water outlet end of the telescopic tube 32, until the water outlet end of the telescopic tube 32 extends out of the wing of the drone. The utility model provides an airborne gimbal for a drone, when the drone carries a water pipe to a high altitude to spray water for fire extinguishing, the water outlet end (i.e., the water outlet) of the telescopic tube 32 is extended to the outside of the wing of the drone through the telescopic plate 31, and then water is sprayed for fire extinguishing, thereby solving the technical problem that after the wings of the drone are unfolded, if the nozzle of the water pipe does not protrude outside the fuselage of the drone, the water sprayed from the water pipe will affect the operation of the wings of the drone, thereby affecting the flight of the drone.

[0035] For the convenience of understanding by those skilled in the art, this embodiment also provides a drone, which includes a drone body and the drone airborne gimbal, wherein the drone body includes a fuselage and a propeller. When the drone is in storage, storage or non-flying state, the propeller is in a folded state; when the drone is ready to fly, the propeller is in an unfolded state to provide the required lift and propulsion to ensure the smooth progress of the flight. The length of the drone airborne gimbal is equal to the length of the fuselage. The drone provided in this embodiment is suitable for firefighting scenes, and is particularly suitable for firefighting scenes with poor outdoor conditions (for example, excessive outdoor wind speed). When the drone is at high altitude and sprays water to extinguish a fire, if the water spray port is within the circle formed by the propeller, even if the water spray port is below the propeller, in the case of excessive outdoor wind speed, the water sprayed from the water spray port will form upward water mist under the action of the wind, affecting the normal operation of the propeller, and further affecting the flight of the drone. In the drone provided in this embodiment, when the propeller of the drone is unfolded, the telescopic plate 31 of the airborne gimbal drives the water spray port to extend outside the circle formed by the propeller to reduce the influence of water mist on the propeller.

[0036] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
