Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) platform installation, in particular to an installation mechanism for a camera-fixed UAV platform for surveying and mapping. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control and its own programmable controller. It takes off and lands vertically using rotating propellers, can hover, and is highly maneuverable. It is commonly used for tasks such as photography and express delivery. Examples include multi-rotor drones and helicopter drones, which are widely used in aerial photography, agricultural plant protection, logistics and transportation, power inspections, environmental monitoring, and emergency rescue.

[0003] Drone surveying is a technology that combines drone technology with surveying and mapping technology, using sensors carried by drones to efficiently acquire and process surface information. Drones can fly quickly and collect large amounts of data, which greatly shortens the surveying and mapping time period compared to traditional manual measurement methods. For example, data collection work that may have taken days or weeks to complete in the past can now be completed in hours and modeling and analysis can be completed quickly. Drones can easily operate in various terrains and environments, including mountainous areas, forests, cities and other difficult-to-reach areas, providing more options and possibilities for surveying and mapping work. Compared with traditional surveying and mapping methods, the cost of drone surveying is relatively low.

[0004] Common camera fixed gimbals for drone mapping connect the gimbal and the drone through a screw hole and a stud on the gimbal. However, since drone mapping requires the camera to be brought to a high altitude, once it falls off, the camera will inevitably be damaged. Using a single screw hole and stud for connection and installation is not safe enough. In view of this, the present application proposes an installation mechanism for a camera fixed gimbal for drone mapping. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides an installation mechanism for a fixed pan-tilt camera for drone surveying and mapping, which has the advantages of firm pan-tilt installation and not easy to fall off. It solves the problem that drone surveying and mapping requires the camera to be brought to a high altitude, and once it falls off, the camera will inevitably be damaged, and the use of a single screw hole and stud for connection and installation is not safe enough.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a mounting mechanism for a fixed gimbal for a camera used in surveying and mapping unmanned aerial vehicles, comprising a drone body, wherein mounting screw holes are provided on two mutually distant side surfaces of the drone body, the mounting mechanism is mounted on the drone body via mounting bolts, the mounting bolts being threadedly mounted in the mounting screw holes, and a gimbal base is rotatably mounted on the bottom of the mounting mechanism;

[0007] The mounting mechanism includes a mounting plate mounted on both sides of the drone body through mounting bolts, a mounting bracket is fixedly mounted on the bottom of the mounting plate, and a mounting positioning hole adapted to the mounting bolt is opened on one side of the mounting plate.

[0008] Furthermore, a camera housing is fixedly mounted on the bottom of the pan / tilt base, a camera is rotatably mounted inside the camera housing, and a glass guard plate adapted to the camera lens is fixedly mounted on the bottom of the camera housing.

[0009] Furthermore, two rotation shafts are rotatably mounted on the inner side wall of the camera housing, and the camera is fixedly mounted between the two rotation shafts.

[0010] Furthermore, an angle motor is fixedly mounted on one side of the camera housing, and an output shaft of the angle motor is fixedly connected to one end of one of the rotating shafts.

[0011] Furthermore, a horizontal motor is fixedly mounted on the top of the bottom horizontal plate of the mounting bracket, a through hole is provided on the top of the bottom horizontal plate of the mounting bracket, and the output shaft of the horizontal motor is fixedly connected to the top of the pan / tilt base through the through hole.

[0012] Furthermore, a mounting rod is fixedly installed on the side of the drone body, a propeller is rotatably installed on the top of the mounting rod, and reinforcement components are provided on the two vertical plates of the mounting bracket.

[0013] Furthermore, the reinforcement assembly includes a sliding kit slidably mounted on the surfaces of two vertical plates of the mounting bracket, two support rods are fixedly mounted on the top of the sliding kit, and a limiting top plate is fixedly mounted on the top of the support rods.

[0014] Furthermore, a locking screw hole is provided on one side of the sliding assembly, and a locking screw is installed on the internal thread of the locking screw hole.

[0015] Compared with the prior art, the present invention provides a mounting mechanism for a fixed pan-tilt camera for UAV surveying and mapping, which has the following beneficial effects:

[0016] The mounting mechanism of the camera fixed gimbal for drone mapping is connected to the drone body by mounting bolts on both sides of the drone body to increase the stability of the connection, and the gimbal base is set on the bottom horizontal plate of the mounting bracket. During flight, even if the mounting bolts on one side fall off, the other side can still support it, reducing the probability of the camera falling. This solves the problem that drone mapping requires the camera to be brought to a high altitude. Once it falls off, the camera will inevitably be damaged, and the use of a single screw hole and stud for connection and installation is not safe enough. BRIEF DESCRIPTION OF THE DRAWINGS
