Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an image acquisition device based on unmanned aerial vehicles. Background Art

[0002] Unmanned aerial vehicles, referred to as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by on-board computers. With the rapid development of drone technology in recent years, drones are frequently used in various types of exploration. When using drones for inspections, users only need to watch images in the background, which greatly speeds up the work efficiency of engineering exploration.

[0003] In the prior art, the image acquisition equipment of most drones is directly installed on the bottom of the drone, but there is a lack of protective measures for the image acquisition equipment. When the drone is flying in the air, it is inevitable that it will collide with birds or tall buildings. If the drone flies at a high speed, the image acquisition equipment will be seriously damaged after the collision, affecting the efficiency of subsequent exploration work. Utility Model Content

[0004] The purpose of the utility model is to provide an image acquisition device based on a drone, so as to solve the problem that the image acquisition device of the drone in the prior art proposed in the above background technology is directly installed on the bottom of the drone, but lacks protective measures for the image acquisition device, and the drone will inevitably collide with birds or tall buildings when flying in the air.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An image acquisition device based on a drone comprises a camera and a protective shell, wherein the camera is arranged inside the protective shell, and limiting grooves are provided between the two sides and the bottom of the protective shell, and the camera head of the camera is arranged in the limiting grooves. A driving motor is fixedly installed on an inner wall of one side of the protective shell, and an output end of the driving motor is fixedly connected to a transmission shaft, and the other end of the transmission shaft is fixedly connected to one side of the camera, and four groups of positioning components are provided on the inner walls of both sides of the protective shell.

[0008] A connecting seat is fixedly connected to the inner wall of the other side of the protective shell, and the circular block is connected to the inside of the connecting seat.

[0009] As a preferred solution of the utility model, a plurality of elastic blocks are arranged on the outer diameter of the circular block at equal intervals, a plurality of arc grooves are opened on the inner diameter of the connecting seat at equal intervals, and the elastic blocks and the arc grooves are offset from each other.

[0010] As a preferred solution of the utility model, the positioning components include a sleeve fixedly connected to the protective shell, the other end of the sleeve is slidably connected to an elastic rod, the other end of the elastic rod is fixedly connected to an L-shaped rod, and the L-shaped rod is arranged in close proximity to the camera.

[0011] As a preferred solution of the utility model, heat dissipation openings are provided on both sides of the protective shell, and dustproof nets are fixedly connected to the heat dissipation openings.

[0012] As a preferred solution of the utility model, four corners of the outer wall of the protective shell are fixedly connected with mounting plates, and fixing bolts are inserted in the mounting plates.

[0013] As a preferred solution of the utility model, buffer pads are provided on both sides of the mounting plate, and the buffer pads are sleeved on the outer sides of the fixing bolts.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) In order to improve the protection of the UAV image acquisition equipment, the camera is mainly used for the image acquisition work of the UAV. The camera is protected by a protective shell to avoid the camera from being damaged when the UAV is flying at high altitude or landing. At the same time, in order to ensure the lightweight of the UAV, the angle adjustment of the camera only uses one set of driving motors. The driving motor can drive the transmission shaft to rotate. When the transmission shaft rotates, it drives the camera to rotate, so that the camera rotates in the limit groove to widely collect images of the external environment. The four sets of positioning components on the inner wall of each side of the protective shell are used to position the camera at four points. On the one hand, it can enhance the stability of the camera during the flight of the UAV and further improve the protection effect. On the other hand, it can also improve the stability of the camera when adjusting the angle. Therefore, the image acquisition device of the UAV has a simple and compact structure, which can effectively protect the image acquisition device and extend the service life of the equipment.

[0016] (2) The driving motor can drive the camera to rotate 45 degrees each time. There are eight sets of elastic blocks and arc grooves. Each time the camera rotates 45 degrees, the elastic block will collide with the next arc groove, thereby further ensuring the stability of the camera after each adjustment.

[0017] (3) The positioning components are fixedly connected to the protective shell through the sleeve, and the elastic rods can be retracted along the sleeve. The L-shaped rod can be made to fit closely to the camera through the elastic rod. One part of the L-shaped rod fits closely to the side wall of the camera, and the other part of the L-shaped rod fits closely to the outer diameter of the camera, thereby clamping the camera like a four-claw structure to ensure the stability of the camera.

A connecting seat 8 is fixedly connected to the inner wall of the other side of the protective shell 2, and the circular block 701 is connected to the inside of the connecting seat 8. The transmission shaft 601 can be regarded as an active shaft that drives the camera 1 to rotate, and the auxiliary shaft 7 can be regarded as a driven shaft that rotates synchronously along the connecting seat 8 with the rotation of the camera 1. The end of the auxiliary shaft 7 away from the camera 1 is clamped with the connecting seat 8 through the circular block 701.
