Description

Technical Field

[0001] This utility model relates to the field of geological monitoring technology, specifically to an image acquisition drone for geological disaster monitoring. Background Technology

[0002] Geological monitoring refers to the long-term tracking of the geological environment and its changes caused by natural geological environment or engineering construction through systematic observation, measurement, analysis and early warning. Its purpose is to prevent geological disasters, ensure engineering safety and provide scientific basis for resource development. With the advancement of technology, drones can be used to collect images to realize the monitoring of geological disasters.

[0003] To improve stability when hovering and taking pictures, existing image acquisition drones add protective components to the outside of the propellers to reduce wind interference, improve the stability of the pictures, and protect the propeller blades when the drone lands. However, adding protective components will affect the control of the propellers and reduce the stability of the drone when moving and shooting. Utility Model Content

[0004] The purpose of this invention is to address the problem that adding protective components to improve stability during hovering photography can affect propeller control and reduce the stability of the drone during mobile photography. This invention provides an image acquisition drone for geological disaster monitoring.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A geological disaster monitoring image acquisition drone includes a body, a telescopic shaft that is slidably connected around the body, a propeller that is fixedly installed at the end of the telescopic shaft away from the body, a protective component that is provided on the outside of the propeller, a threaded disc that is rotatably connected inside the body, and a rack that is fixedly connected to the top of the inner side of the telescopic shaft.

[0007] Furthermore, a motor is fixedly installed above the threaded disc inside the machine body, and the motor is connected to the threaded disc for driving the threaded disc to rotate in both directions.

[0008] Furthermore, the bottom of the threaded disc has a spiral pattern, and the telescopic shaft extends inward to the bottom of the threaded disc. The rack at the top of the inner side of the telescopic shaft meshes with the threaded disc. Therefore, when the threaded disc rotates, it can drive the telescopic shaft to retract inward or extend outward simultaneously.

[0009] Furthermore, the protective assembly includes a mounting frame, a mounting frame fixedly mounted on the middle of the telescopic shaft, a fixed guard plate fixedly mounted on the top of the mounting frame, movable guard plates slidably connected to both sides inside the fixed guard plate, a spindle fixedly mounted at the center inside the fixed guard plate and passing through the center inside the movable guard plate, springs fixedly connected between the end of the movable guard plate inside the fixed guard plate and the inner wall of the fixed guard plate, a piston rod fixedly mounted inside the body, the piston rod extending outward to the center inside the telescopic shaft, and a connecting groove provided at the connection between the telescopic shaft and the fixed guard plate inside the mounting frame, through which the inner cavity of the telescopic shaft is connected to the inner cavity of the fixed guard plate.

[0010] Furthermore, after the movable guard plates on both sides extend, they can form a ring with the fixed guard plate and wrap around the outside of the propeller to protect the propeller and block wind interference.

[0011] Furthermore, all the springs are wrapped around the outside of the spindle to improve the stability when the springs are in action.

[0012] Furthermore, a camera is fixedly mounted on the bottom of the device via a gimbal for taking photos or videos.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention, through the telescopic movement of the drive shaft and propeller, and in conjunction with protective components, enables the propeller to retract inward during hovering photography and landing, reducing the overall size of the drone and mitigating wind interference. Simultaneously, the protective plate unfolds to reduce the impact of wind on the propeller, improving the stability of the drone during hovering photography and also protecting the propeller during landing. During normal flight and mobile photography, the telescopic shaft and propeller extend outward while the protective plate retracts, ensuring that the outer side of the propeller is not obstructed, guaranteeing normal propeller control, and improving the stability of the drone during mobile photography.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] A preferred embodiment of the present invention, an image acquisition drone for geological disaster monitoring, will be described in detail below, such as... Figures 1-5 As shown, an image acquisition drone for geological disaster monitoring includes a body 1. A telescopic shaft 2 is slidably connected around the body 1. A propeller 3 is fixedly installed at the end of the telescopic shaft 2 away from the body 1. A protective component 4 is provided on the outside of the propeller 3. A threaded disc 5 is rotatably connected inside the body 1. A motor is fixedly installed above the threaded disc 5 inside the body 1 and is connected to the threaded disc 5 for driving the threaded disc 5 to rotate in both directions. A rack 6 is fixedly connected to the top of the inner side of the telescopic shaft 2. The bottom of the threaded disc 5 has helical patterns. The telescopic shaft 2 extends inward to the bottom of the threaded disc 5. The rack 6 at the top of the inner side of the telescopic shaft 2 and the threaded disc 5 are mutually meshed. Therefore, when the threaded disc 5 rotates, it can drive the telescopic shaft 2 to retract inward or extend outward simultaneously.

[0027] A camera 7 is fixedly mounted on the bottom of the body 1 via a gimbal for taking photos or videos.

[0028] Furthermore, such as Figures 5-9As shown, the protective component 4 includes a mounting bracket 41. The mounting bracket 41 is fixedly installed in the middle of the telescopic shaft 2. A fixed protective plate 42 is fixedly installed at the top of the mounting bracket 41. Movable protective plates 43 are slidably connected to the two sides inside the fixed protective plate 42. After the two movable protective plates 43 extend, they can form a ring with the fixed protective plate 42 and wrap around the outside of the propeller 3 to protect the propeller 3 and block wind interference.

[0029] A spindle 44 is fixedly installed at the center of the fixed guard plate 42, and the spindle 44 passes through the center of the movable guard plate 43. A spring 45 is fixedly connected between the movable guard plate 43 and the inner wall of the fixed guard plate 42. The spring 45 is wrapped around the outside of the spindle 44 to improve the stability when the spring 45 is in action. A piston rod 46 is fixedly installed inside the body 1. The piston rod 46 extends outward to the center of the telescopic shaft 2. A connecting groove 47 is provided at the connection between the telescopic shaft 2 and the fixed guard plate 42 inside the mounting bracket 41. The inner cavity of the telescopic shaft 2 is connected to the inner cavity of the fixed guard plate 42 through the connecting groove 47.

[0030] The working principle of this utility model is as follows:

[0031] In use, the propeller 3 is extended outward by the telescopic shaft 2, and the rotation of the propeller 3 is used to achieve the flight and movement of the drone, and it is used in conjunction with the camera 7 at the bottom of the body 1 to take pictures.

[0032] When the drone reaches the designated area and needs to take pictures of a certain geological site, the motor inside the body 1 drives the threaded disk 5 to rotate. During the rotation of the threaded disk 5, the meshing between the threaded disk 5 and the inner top rack 6 of the bottom telescopic shaft 2 can simultaneously drive the outer telescopic shaft 2 to retract inward, thereby driving the propeller 3 to retract towards the center, reducing the overall size of the drone and mitigating wind interference.

[0033] As the telescopic shaft 2 and propeller 3 retract inward, the telescopic shaft 2 retracts inward relative to the piston rod 46, causing the piston rod 46 to compress the gas inside the telescopic shaft 2. This gas then enters the interior of the fixed guard plate 42 through the connecting groove 47, thereby pushing the movable guard plate 43 to extend outward along the spindle 44 and the tension spring 45. After the two ends of the movable guard plate 43 merge, they form a ring with the fixed guard plate 42, thereby reducing the impact of wind on the propeller 3 and improving the stability of the drone when taking pictures.

[0034] When the drone lands, the telescopic shaft 2 and propeller 3 can also be retracted, and the fixed guard plate 42 and the movable guard plate 43 can protect the propeller 3.

[0035] When flight and mobile shooting are required, the drive screw disk 5 is reversed to move the telescopic shaft 2 outward. At the same time, the air pressure inside the fixed guard plate 42 decreases, and the moving guard plate 43 will retract to both sides under the action of the restoring force of the spring 45, so as not to block the outside of the propeller 3, ensuring the normal operation of the propeller 3 and improving the stability of the drone during mobile shooting.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
