Description

Technical Field

[0001] This invention relates to the field of drone surveying technology, specifically a surveying aerial photography drone with a waterproof camera. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment or onboard computer program control systems. UAVs have a simple structure and low operating cost. They can not only perform the tasks that manned aircraft can perform, but are also suitable for tasks that manned aircraft cannot perform. They play a significant role in emergency response and early warning in case of emergencies.

[0003] Drones also have certain applications in engineering surveying. By mounting a camera surveyor on a drone and controlling the drone to fly to a suitable aerial position, aerial surveying can be achieved using the camera surveyor. However, because drones are small and lack rain protection, the camera surveyor is easily corroded by rainwater. Some drones use rain covers on the top of the camera surveyor to achieve waterproofing. However, the camera surveyor needs to adjust its tilt angle during the surveying process. When the camera surveyor is tilted, a large rain cover can easily obstruct the surveying surface, while a small rain cover cannot completely protect against rain. Summary of the Invention

[0004] The purpose of this invention is to provide a surveying and aerial photography drone with a waterproof camera function to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A surveying aerial photography drone with a waterproof camera function includes a drone body and a camera body. The drone body has a suspension cover mechanism at its bottom, and the camera body is installed inside the suspension cover mechanism. The suspension cover mechanism includes a mounting frame component, a suspension bracket, a top cover assembly, and a drive component. The top of the suspension bracket is fixed to the bottom of the drone body, and the suspension bracket has two downward-facing support arms. The mounting frame component is located at the bottom end of the suspension bracket and its sides are rotatably connected to the two support arms of the suspension bracket. The camera body is mounted on the mounting frame component, and the top cover assembly is located on the mounting frame component. The top of the cover assembly is used to cover the camera body and the mounting frame components. The side of the cover assembly slides up and down with the support arm of the suspension bracket. The suspension bracket is telescopic and has a push-pull hinge seat on its telescopic part. The push-pull hinge seat is connected to the middle of the suspension bracket through a telescopic push-pull rod. The drive component is located on the suspension bracket and is connected to the cover assembly to drive it to move up and down. The cover assembly is also connected to the end of the mounting frame components through a transmission connector. When the cover assembly moves up and down, it can drive the mounting frame components to rotate around the connection point with the support arm of the mounting frame components through the transmission connector.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention.

[0025] In one embodiment, such as Figures 1-3 As shown, a surveying aerial photography drone with a waterproof camera function includes a drone body 1 and a camera body 2. The drone body 1 has a suspension cover mechanism 3 at its bottom, and the camera body 2 is installed inside the suspension cover mechanism 3. The suspension cover mechanism 3 includes a mounting frame component 31, a suspension bracket 32, a top cover assembly, and a drive component 35. The top of the suspension bracket 32 ​​is fixed to the bottom of the drone body 1, and the suspension bracket 32 ​​has two downward-facing support arms. The mounting frame component 31 is located at the bottom end of the suspension bracket 32, and its side is rotatably connected to the two support arms of the suspension bracket 32. The camera body 2 is mounted on the mounting frame component 31, and the top cover assembly is located on the top of the mounting frame component 31. The upper cover assembly is used to cover the camera body 2 and the mounting frame component 31. The side of the upper cover assembly slides up and down with the support arm of the suspension bracket 32. The suspension bracket 32 ​​is telescopic and has a push-pull hinge seat 341 on its telescopic part. The push-pull hinge seat 341 is connected to the middle part of the suspension bracket 32 ​​through the telescopic push-pull rod 342. The driving member 35 is provided on the suspension bracket 32. The driving member 35 is connected to the upper cover assembly and drives it to move up and down. The upper cover assembly is also connected to the end of the mounting frame component 31 through the transmission connector 37. When the upper cover assembly moves up and down, it can drive the mounting frame component 31 to rotate around the connection point with the support arm of the mounting frame component 31 through the transmission connector 37.

[0026] In this embodiment, the flight of the UAV body 1 can drive the suspension cover mechanism 3 and the camera body 2 to move, and the camera body 2 performs aerial mapping through photography. Since the camera body 2 is located under the upper cover assembly, the upper cover assembly can shield the camera body 2 from rain, thus providing a certain degree of waterproofing. When the camera body 2 needs to change its tilt angle for shooting and mapping, the control drive component 35 drives the upper cover assembly to move vertically away from or towards the camera body 2. When the upper cover assembly moves, it can drive the mounting frame component 31 through the transmission connector 37 and drive the camera body 2 to rotate around the mounting frame component 31 and the suspension bracket 32. The connection of the support arm rotates, thereby changing the tilt angle of the camera body 2 and enabling tilted shooting and mapping. Since the upper cover assembly is telescopic and the telescopic part is connected to the suspension bracket 32 ​​through the telescopic push-pull rod 342, when the upper cover assembly moves upward, the telescopic push-pull rod 342 gradually changes to a horizontal state, thereby pushing the telescopic part of the upper cover assembly to extend, increasing the waterproof coverage area of ​​the upper cover assembly. Furthermore, the upper cover assembly moves upward and away from the camera body 2, avoiding interference when the camera body 2 rotates upward and tilts. At the same time, the upper cover assembly moves away from the camera body 2 without affecting the shooting and mapping surface of the camera body 2, thereby effectively improving waterproofness.

[0027] In one embodiment, such as Figure 4 As shown, the upper cover assembly includes an outer cover 33 and a telescopic cover 34. Both the outer cover 33 and the telescopic cover 34 have U-shaped cross-sections. The outer cover 33 has a sliding buckle seat 361 on its side, and the support arm of the suspension bracket 32 ​​has a guide rail 36. The sliding buckle seat 361 slides onto the guide rail 36. The telescopic cover 34 is inserted inside the outer cover 33, and the top wall of the telescopic cover 34 is provided with a push-pull hinge seat 341, which is hinged to one end of the telescopic push-pull rod 342. The side wall of the telescopic cover 34 has... The outer cover 343 has a telescopic cover 343 and a sliding protrusion 332 on the inner side wall of the outer cover 343 that is sealed and slidably fastened within the telescopic cover 343; the end of the outer cover 33 away from the telescopic cover 34 is connected to the drive member 35; in this embodiment, the outer cover 33 and the telescopic cover 34 adopt a U-shaped structure to effectively block rainwater, and can achieve vertical and stable movement with the support arm of the suspension bracket 32 ​​through the guide rail 36 and the sliding fastener seat 361; and the telescopic cover 34 can extend and retract within the outer cover 33 by the push and pull of the telescopic push and pull rod 342;

[0028] In one embodiment, such as Figures 2-4As shown, the outer cover 33 has a through hole 331 at the end away from the telescopic cover 34. The driving component 35 includes a screw 351, an inner spiral tube 352, and a drive motor 353. The inner spiral tube 352 is installed inside the through hole 331 and rotates with the inner wall. The screw 351 passes through the inner spiral tube 352 and rotates with it. The top of the screw 351 is rotatably connected to the side of the suspension bracket 32. The drive motor 353 is mounted on the suspension bracket 32, and its output end is connected to the screw 351 and drives it to rotate. In this embodiment, the drive motor 353 can drive the screw 351 to rotate. Through the spiral engagement of the screw 351 and the inner spiral tube 352, both the inner spiral tube 352 and the upper cover assembly move vertically along the axis of the screw 351.

[0029] In one embodiment, such as Figure 2 and Figure 3 As shown, the mounting frame component 31 has a supporting rotating column 38 on its end side wall, and the supporting rotating column 38 is rotatably connected to the support arm of the suspension bracket 32; the transmission connector 37 includes a drive rack 371 and a gear 372, the gear 372 is disposed on the supporting rotating column 38, the drive rack 371 is vertically arranged and one end is connected to the upper cover assembly, and the drive rack 371 meshes with the gear 372; in this embodiment, due to the up and down movement of the upper cover assembly, the drive rack 371 moves up and down, and the meshing of the drive rack 371 and the gear 372 can drive the supporting rotating column 38 to rotate, thereby driving the mounting frame component 31 and the camera body 2 to rotate and adjust the tilt angle;

[0030] In one embodiment, such as Figure 4 As shown, the inner edge of the outer cover 33 is provided with a sealing gasket 333, which slides in a sealing manner with the top wall of the telescopic cover 34; the sealing gasket 333 is made of rubber material; in this embodiment, since the outer cover 33 is placed between the telescopic cover 34 and the outer cover 33, the gap between the contact surfaces of the telescopic cover 34 and the outer cover 33 can be sealed; rainwater is prevented from entering the interior of the outer cover 33; and the waterproof performance is improved.

[0031] In one embodiment, such as Figure 2 , Figure 3 and Figure 5As shown, the mounting frame component 31 includes a tail support groove 311 and a horizontal cover 312. One end of the tail support groove 311 is rotatably connected to the support arm of the suspension bracket 32. The tail of the camera body 2 is inserted into the tail support groove 311. The suspension bracket 32 ​​is located at the other end of the tail support groove 311, and the bottom of the horizontal cover 312 forms an installation port. The installation port at the bottom of the horizontal cover 312 has multiple bottom support mounting parts 313. The bottom support mounting parts 313 can detachably install the camera body 2 at the bottom of the horizontal cover 312. In this embodiment, since the bottom end of the horizontal cover 312 has an installation port, the tail of the camera body 2 can be placed in the tail support groove 311 through the installation port and installed on the horizontal cover 312 as a whole through the bottom support mounting parts 313, thereby enabling quick installation and disassembly.

[0032] In one embodiment, such as Figure 5 As shown, the base support mounting component 313 includes two support rods 3131, which are symmetrically mounted on the side of the horizontal cover 312. One end of each support rod 3131 is hinged to the side wall of the horizontal cover 312 via a connecting support 3133. The end of the base support mounting component 313 away from the connecting support 3133 has a connecting part 3132. The two connecting parts 3132 can abut against each other and be fastened with bolts. In this embodiment, since the ends of the support rods 3131 are hinged to the side of the horizontal cover 312, the two connecting parts 3132 can be opened by moving them from both sides after being disassembled, thus facilitating the placement of the camera body 2 inside the horizontal cover 312. Subsequently, the two connecting parts 3132 are fastened with bolts to maintain a stable state. The operation is convenient.

[0033] The above embodiment provides a surveying aerial photography drone with a waterproof camera function. When the camera body 2 needs to change its tilt angle for shooting and surveying, the control drive 35 drives the upper cover assembly to move vertically away from or towards the camera body 2. When the upper cover assembly moves, it can drive the mounting frame component 31 through the transmission connector 37 and drive the camera body 2 to rotate around the connection between the mounting frame component 31 and the suspension bracket 32 ​​arm, thereby changing the tilt angle of the camera body 2 and realizing tilted shooting and surveying. Since the upper cover assembly can extend and retract, and the extendable part is connected to the suspension bracket 32 ​​through the telescopic push-pull rod 342, when the upper cover assembly moves upward, the telescopic push-pull rod 342 gradually changes to a horizontal state, thereby pushing the extendable part of the upper cover assembly to extend, increasing the waterproof coverage area of ​​the upper cover assembly. Furthermore, the upper cover assembly moves upward and away from the camera body 2, avoiding interference when the camera body 2 rotates upward and tilts. At the same time, the upper cover assembly moves away from the camera body 2 without affecting the shooting and surveying surface of the camera body 2, thereby effectively improving waterproofing.

[0034] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
