Description

A drone monitoring device Technical Field

[0001] This utility model relates to the field of intelligent inspection technology for power facilities, and in particular to a drone monitoring device. Background Technology

[0002] As the core carrier of power transmission, high-voltage power grids are exposed to complex natural environments for extended periods. The condition of their line insulators, fittings, and conductors directly affects power supply safety. Especially in mountainous and forested areas with harsh geographical environments, equipment is susceptible to natural factors such as wind erosion, lightning strikes, and icing. Traditional manual maintenance faces challenges such as low efficiency, high risk, and numerous blind spots, making intelligent monitoring methods urgently needed to achieve efficient fault early warning and precise maintenance.

[0003] Current mainstream inspection methods include visual observation by ground vehicles and scanning with handheld devices, but these are difficult to implement in steep mountainous areas. Aerial inspection technology using drones equipped with visible light, infrared, or lidar monitoring heads has emerged to address this need, allowing for multi-angle scanning of infrastructure through flight path planning. While this method improves coverage and flexibility, its operational mode still has significant drawbacks: drones must fly close to the infrastructure to obtain high-precision data, and the monitoring heads are directly exposed to the external environment.

[0004] The biodiversity of mountainous areas leads to frequent aerial biological activity, making existing UAV monitoring heads prone to collisions with these organisms during missions. Sticky contaminants, such as bird droppings, insect carcasses, and pollen, adhere to the optical lenses and sensor surfaces of the monitoring heads, causing problems such as blurred images, thermal imaging distortion, and missing point cloud data. Frequent takeoffs and landings for cleaning severely reduce operational efficiency, and the inability to clean in flight can lead to the loss of critical data, becoming a core bottleneck restricting the reliability of the technology. Summary of the Invention

[0005] To overcome the drawback of pollutants affecting the accuracy of monitoring data, this utility model provides a drone monitoring device, which aims to solve the above-mentioned shortcomings.

[0006] A drone monitoring device includes a drone, a connecting base connected to the bottom of the drone, a monitoring camera mounted on the bottom of the connecting base, a first protective shell connected to the bottom side of the drone, a second protective shell slidably connected inside the first protective shell, the first and second protective shells having a "U" shaped cross-section, the first and second protective shells together enclosing the monitoring camera, a fixing base connected to the outside of the first protective shell, the first protective shell having a notch at the fixing base, a motor mounted on the fixing base, a rack connected to the outside of the second protective shell, the rack rotatably connected between the fixing base and the first protective shell, the output shaft of the motor connected to the rack, the rack meshing with the gear, and a sealing assembly for sealing the bottom of the second protective shell.

[0007] Furthermore, the sealing assembly includes a mounting plate, and the mounting plate is connected to the bottom corner of the second protective housing. A rotating shaft is rotatably connected between the mounting plates on the left and right sides. A sealing gasket is connected to the rotating shaft. The two sealing gaskets seal the bottom opening of the second protective housing. Both ends of the rotating shaft pass through the mounting plate and are fitted with torsion springs. One end of the torsion spring is connected to the mounting plate, and the other end is connected to the rotating shaft.

[0008] Furthermore, a roller is rotatably connected to the bottom bent end face of the first protective shell, and the roller contacts the inner side of the second protective shell.

[0009] Furthermore, a scraper is connected to the bent bottom surface of the first protective shell, and the scraper is slidably connected to the outer side of the second protective shell.

[0010] Furthermore, a mosquito-repellent lamp is installed on the front side of the first protective shell.

[0011] Furthermore, a protective outer shell is connected to the side of the first protective outer shell that is connected to the fixed base, and the protective outer shell encloses the motor and the gear.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] By using a motor-driven gear-rack mechanism, the second protective shell slides precisely along the first protective shell and retracts, simultaneously rotating and unfolding the sealing gasket. This achieves zero-exposure opening and closing of the monitoring camera, forming a dual barrier of "physical isolation of the outer shell + flexible sealing at the bottom," completely preventing bird droppings, insect carcasses, and other contaminants from adhering to the lens and ensuring the accuracy of monitoring data from the source.

Detailed Implementation

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0021] Example: A drone monitoring device, as shown in Figures 1-5, includes a drone 1, a connecting base 2, a monitoring camera 3, a first protective shell 4, a second protective shell 5, a fixing base 6, a gear 7, a motor 8, a rack 9, and a sealing assembly. The drone 1 is connected to the connecting base 2 at its bottom, and the monitoring camera 3 is mounted on the bottom of the connecting base 2. The monitoring camera 3 can rotate freely at the bottom of the connecting base 2. The first protective shell 4 is connected to the bottom side of the drone 1, and the second protective shell 5 is slidably connected inside the first protective shell 4. The cross-sections of the first protective shell 4 and the second protective shell 5 are shaped like an "U", thus preventing them from completely sliding apart. The monitoring camera 3 is enclosed by 5. A fixing seat 6 is connected to the outside of the first protective shell 4. The first protective shell 4 has a notch at the fixing seat 6. A motor 8 is installed on the fixing seat 6. A rack 9 is connected to the outside of the second protective shell 5. A gear 7 is rotatably connected to the notch between the fixing seat 6 and the first protective shell 4. The output shaft of the motor 8 is connected to the gear 7. The gear 7 meshes with the rack 9. A sealing component is provided at the bottom of the second protective shell 5 to seal its bottom. The double-layer interlocking protective shell slides relative to each other under the drive of the motor 8 and controlled by the gear 7-rack 9 mechanism to realize the exposure and sealing of the monitoring camera 3. The sealing component opens and closes automatically to ensure the continuity of bottom protection.

[0022] As shown in Figures 2 and 4, the sealing assembly includes a mounting plate 10, a rotating shaft 11, a sealing gasket 12, and a torsion spring 13. Mounting plates 10 are connected to the bottom corners of the second protective housing 5. A rotating shaft 11 is rotatably connected between the mounting plates 10 on both sides. Sealing gaskets 12 are connected to the rotating shaft 11, and the two sealing gaskets 12 seal the bottom opening of the second protective housing 5. Both ends of the rotating shaft 11 pass through the mounting plates 10 and are fitted with torsion springs 13. One end of the torsion spring 13 is connected to the mounting plate 10, and the other end is connected to the rotating shaft 11. When the second protective housing 5 rises and falls, the rotating shaft 11 is moved synchronously through the mounting plates 10. When the sealing gasket 12 contacts the bottom of the monitoring camera 3, it rotates under force, causing the torsion spring 13 to unfold; when it disengages, the torsion spring 13 automatically rebounds and closes.

[0023] As shown in Figure 5, it also includes a roller 14. The roller 14 is rotatably connected to the bottom bent end face of the first protective shell 4. The roller 14 contacts the inner side of the second protective shell 5. When the second protective shell 5 slides, its inner wall presses the roller 14 to rotate, converting sliding friction into rolling friction.

[0024] As shown in Figure 5, it also includes a scraper 15. The scraper 15 is connected to the bent bottom surface of the first protective shell 4, and the scraper 15 is slidably connected to the outer side of the second protective shell 5.

[0025] As shown in Figure 1, it also includes a mosquito repellent lamp 16. The mosquito repellent lamp 16 is installed on the front side of the first protective shell 4. The mosquito repellent lamp 16 continuously emits 365nm ultraviolet light and 40kHz sound waves during the flight of the drone 1 to repel flying insects within a radius of 5 meters, thereby reducing collision and attachment from the source.

[0026] As shown in Figure 2, it also includes a protective shell 17. The protective shell 17 is connected to the side of the first protective shell 4 connected to the fixed base 6. The protective shell 17 continuously wraps around the motor 8 and gear 7, preventing rainwater and sand from corroding the transmission system.

[0027] Staff control drone 1 to take off, turn on mosquito repellent lamp 16, and proceed to the testing area. Before starting the testing, motor 8 is turned on, driving gear 7 to rotate. After gear 7 meshes with rack 9, it pushes rack 9 and the second protective shell 5 upwards. The second protective shell 5 retracts into the first protective shell 4. At this time, the moving second protective shell 5 causes roller 14 to rotate. Roller 14 changes the sliding friction between the first and second protective shells 4 and 5 into rolling friction, reducing friction and friction loss. Scraper 15 at the bottom of the first protective shell 4 scrapes away dust and other contaminants from the surface of the second protective shell 5 and protects the rolling gap of roller 14. As the second protective shell 5 rises... The mounting plate 10 pulls the rotating shaft 11 upward, and the top surface of the sealing gasket 12 is pressed against the bottom of the monitoring camera 3, thereby causing the sealing gasket 12 and the rotating shaft 11 to rotate around the mounting plate 10, torsion spring 13, and finally the two sealing gaskets 12 rotate and unfold to both sides respectively. Moreover, the rubber sealing gasket 12 is adaptively bent after being pressed against the monitoring camera 3, with little pressure on the monitoring camera 3 and without affecting the operation of the monitoring camera 3. After the scanning function area of ​​the monitoring camera 3 is fully exposed, the monitoring camera 3 is turned on and moved by the drone 1 to monitor the facilities in the target area. During the monitoring process, it scans nearby organisms at all times. If there are high-density organisms on the monitoring path, the monitoring path is changed and the monitoring camera 3 is closed.

[0028] After the path change and inspection are completed, the monitoring camera 3 needs to be sealed. The specific steps are as follows: turn on the motor 8, reverse the motor 8 to drive the gear 7 to reverse, the gear 7 meshes with the rack 9 to make the second protective shell 5 slide downward, the sealing gasket 12 and the rotating shaft 11 move downward with the second protective shell 5 through the mounting plate 10, the end of the sealing gasket 12 slides along the side of the monitoring camera 3, after the end of the sealing gasket 12 is separated from the monitoring camera 3, the torsion spring 13 twists, making the rotating shaft 11 rotate in the mounting plate 10, the two sealing gaskets 12 rotate towards the middle, and the bottom of the second protective shell 5 is sealed.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
