Description

Technical Field

[0001] This utility model relates to the field of water conservancy survey technology, specifically a water conservancy survey device based on unmanned aerial vehicles (UAVs). Background Technology

[0002] Water conservancy survey refers to the surveying and geological exploration conducted for river management and water resource development, utilization and protection. In the river basin or region to be developed, it investigates and studies the nature, function and inherent laws of relevant natural phenomena, evaluates and predicts the possible mutual influence and various problems between various water conservancy facilities and the natural environment, and provides basic data and scientific basis for optimizing the planning, design, construction and operation of water conservancy projects.

[0003] Existing drone devices used for water conservancy surveys often encounter challenges due to the complex terrain involved, such as river and lake banks, reservoir slopes, and wetlands. These areas are characterized by uneven surfaces, loose stones, or abundant vegetation. Current drones may rely solely on the camera's structural protection (e.g., lens caps), which is insufficient to effectively address the unique risks of water conservancy scenarios. This results in the camera being directly exposed to collision risks upon landing, making it highly susceptible to damage and safety issues. Furthermore, the lack of practicality due to the difficulty in protecting the camera during landing hinders the development of a drone-based water conservancy survey device. Therefore, we propose a drone-based water conservancy survey device to address these problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a water conservancy survey device based on a drone, including a drone body 1, a camera device 2 is provided on the lower side of the drone body 1, four first fixing blocks 3 are fixedly connected to the lower surface of the drone body 1, a protective cover 4 is provided between two first fixing blocks 3 on one side, the protective cover 4 can be made of transparent material to facilitate viewing the status of the internal camera device 2, a drive rod 5 is fixedly sleeved inside the protective cover 4, the protective cover 4 is rotatably connected between two first fixing blocks 3 through the drive rod 5, a drive box 6 is fixedly connected to the rear surface of the drone body 1, a cavity 10 is opened inside the drive box 6, a drive assembly is provided inside the cavity 10, two second fixing blocks 7 are fixedly connected to both sides of the drone body 1, a rotating rod 8 is fixedly connected between two second fixing blocks 7 on one side, a landing gear 9 is rotatably sleeved on the outside of the rotating rod 8, and a buffer assembly is provided on the outside of the rotating rod 8.

[0024] Among them, the camera device 2 is an existing structure and is known to those skilled in the art. It can be driven to rotate by the control module, thereby realizing the taking of pictures from different angles, which is convenient for water conservancy survey work.

[0025] The drive assembly includes a connecting rod 11, which is rotatably connected inside the cavity 10. The rear ends of both drive rods 5 rotatably penetrate into the cavity 10. Sprockets 12 are fixedly sleeved on the outside of the connecting rod 11 and the outside of the left drive rod 5. Chains 13 are meshed with the outside of the two sprockets 12. Through the cooperation between the two sprockets 12 and the chain 13, the connecting rod 11 can be driven to rotate synchronously when the left drive rod 5 rotates.

[0026] Gears 14 are fixedly fitted on the outside of both the connecting rod 11 and the right drive rod 5. The two gears 14 mesh with each other. Through the transmission of the two gears 14, the connecting rod 11 can rotate and drive the right drive rod 5 to rotate in the opposite direction. Finally, the two drive rods 5 rotate in the opposite direction, thereby achieving the closure of the two protective covers 4. This facilitates the protection of the camera device 2 when the UAV lands on complex terrain, and also facilitates water conservancy survey work.

[0027] A motor 15 is fixedly connected to the rear surface of the drive box 6. The output shaft of the motor 15 rotates through the interior of the drive box 6. The output shaft of the drive box 6 is fixedly connected to the left drive rod 5 through a coupling.

[0028] Among them, the motor 15 is matched with a power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail in this article.

[0029] The buffer assembly includes two circular plates 16, both of which are fixedly sleeved on the outside of the rotating rod 8. Buffer torsion springs 17 are fixedly connected between the opposite surfaces of the two circular plates 16 and the landing gear 9, and the buffer torsion springs 17 are movably sleeved on the outside of the rotating rod 8.

[0030] The upper surface of the drone body 1 is provided with a fan compartment 18. Two air outlet pipes 19 are fixedly connected to the outside of the fan compartment 18. The ends of the two air outlet pipes 19 are provided with connecting hoses 20. A flange 21 is provided between the air outlet pipes 19 and the connecting hoses 20. The end of the connecting hose 20 away from the air outlet pipes 19 is fixedly connected to the protective cover 4. The connecting hose 20 and the interior of the protective cover 4 are connected. Through the cooperation between the fan inside the fan compartment 18, the air outlet pipes 19 and the connecting hoses 20, it is convenient to blow away the dust on the surface of the lens of the camera device 2 when it is dusty, thereby improving the clarity of the subsequent shooting by the camera device 2.

[0031] Flange 21 can be configured as a swivel flange to ensure the stability between the air outlet duct 19 and the connecting hose 20.

[0032] A heating sleeve 22 is fitted over the air outlet duct 19. A support block 23 is fixedly connected to the outside of the heating sleeve 22. The support block 23 is fixedly connected to the upper surface of the UAV body 1.

[0033] A control box 24 is installed on the upper surface of the drone body 1. The control box 24 is connected to the heating sleeve 22. When the drone moves from a low-temperature environment to a high-temperature and high-humidity environment, or when the lens surface temperature is lower than the ambient dew point temperature, the heating sleeve 22 can be activated by the control box 24 to heat the air blown out by the connecting hose 20. This effectively prevents water vapor condensation and eliminates fogging at the source. Alternatively, if raindrops or water mist adhere to the lens surface, the hot air can accelerate the evaporation of moisture through heat conduction and airflow impact, while blowing away larger water droplets to restore a clear field of view and ensure image clarity.

[0034] Working principle:

[0035] When the UAV-based water conservancy survey device is in use, the motor 15 is started by the external control component when the UAV needs to land. The rotation of the motor 15 drives the left drive rod 5 to rotate. The rotation of the left drive rod 5, along with the transmission of the sprocket 12 and the chain 13, enables the rotation of the connecting rod 11. Subsequently, the right drive rod 5 is rotated by the transmission of the two gears 14. At this time, the two drive rods 5 rotate in opposite directions, and the rotation of the two drive rods 5 enables the protective cover 4 to close, thereby protecting the camera device 2 during landing.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
