Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and particularly to a small multi-functional auxiliary device for unmanned aerial vehicle inspections. Background Art

[0002] An unmanned aerial vehicle is an unpiloted aircraft controlled by a radio remote control device or an on-board program control device, with the ability to fly autonomously or semi-autonomously, capable of performing complex aerial tasks, and is often referred to as an "aerial robot". Small unmanned aerial vehicles generally refer to unmanned aerial vehicles weighing between a few hundred grams and several kilograms. They are relatively larger than micro unmanned aerial vehicles, with longer endurance and stronger flight stability. Small unmanned aerial vehicles are commonly used in fields such as aerial photography, agricultural plant protection, and logistics distribution. They can carry cameras or sensors with higher resolutions for taking high-quality aerial images, performing plant protection and monitoring, and carrying out tasks such as express delivery and logistics.

[0003] When an unmanned aerial vehicle is performing inspection flight operations, it may encounter extreme weather. For example, when performing inspection operations in hazy weather or sandstorm weather, as the unmanned aerial vehicle flies for a long time, the dust in the air will adhere to the monitoring probe, affecting the shooting clarity of the unmanned aerial vehicle. At this time, cleaning operations need to be carried out on the monitoring probe. The traditional method uses a single dry brush to rub the lens of the monitoring probe for cleaning operations, and the dust cannot be removed well, so the cleaning effect is not ideal. In view of the above situation, the inventor believes that there is an urgent need for a small multi-functional auxiliary device for unmanned aerial vehicle inspections. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that when an unmanned aerial vehicle encounters hazy or sandstorm weather, the traditional method of cleaning the lens of the monitoring probe has an unsatisfactory effect, and to propose a small multi-functional auxiliary device for unmanned aerial vehicle inspections.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] A small multi-functional auxiliary device for unmanned aerial vehicle inspections includes a drone housing. Inside the drone housing, a water tank is fixedly connected. On the surface of the drone housing, an inspection probe is fixedly connected. On the inner top wall of the drone housing, a U-shaped plate is fixedly connected. Inside the wall of the drone housing, a drive shaft is rotatably connected. One end of the drive shaft is fixedly connected with a V-shaped cleaning brush, and the surface of the V-shaped cleaning brush is in frictional contact with the surface of the inspection probe. Inside the wall of the inspection probe, an annular water outlet pipe is fixedly connected. On the surface of the U-shaped plate, a cleaning mechanism is provided.

[0007] Preferably, the cleaning mechanism includes a motor fixedly connected to the surface of the U-shaped plate. The output end of the motor is fixedly connected with a moving disk. A partition is fixedly connected to the inner wall of the water tank. A piston plate is slidably connected to the inner wall of the water tank. One end of the piston plate penetrates the surface of the U-shaped plate. The piston plate is adapted to the space formed by the water tank and the partition.

[0008] Further, one end of the piston plate close to the moving disk is fixedly connected with a C-shaped rod. A pair of hemispherical bumps are fixedly connected to the surface of the C-shaped rod. A wavy annular groove is formed on the surface of the moving disk. The hemispherical bumps are installed inside the wavy annular groove and are adapted to it. The inner walls of the water tank and the annular water outlet pipe are fixedly connected with the same drain pipe.

[0009] Preferably, a first one-way valve is installed on the inner wall of the partition. An air inlet pipe is fixedly connected to the inner top wall of the water tank. A second one-way valve is installed on the surface of the air inlet pipe.

[0010] Further, one end of the drive shaft away from the V-shaped cleaning brush is fixedly connected with a gear. A limiting plate is fixedly connected to the inner bottom wall of the UAV housing. A rotating shaft is rotatably connected to the inner wall of the limiting plate. One end of the rotating shaft is fixedly connected with a driving disk. A plurality of first teeth and second teeth are fixedly connected to the inner surface of the driving disk. The first teeth are engaged with the gear. The second teeth are engaged with the gear.

[0011] Preferably, a driving wheel is fixedly connected to the surface of the output end of the motor. A driven wheel is fixedly connected to one end of the rotating shaft. The surfaces of the driving wheel and the driven wheel are sleeved with the same belt in a tensioned manner. An avoidance hole is formed on the surface of the U-shaped plate. The belt is installed inside the avoidance hole.

[0012] Further, a plurality of sliding rods are fixedly connected to the lower surface of the UAV housing. The surfaces of the plurality of sliding rods are all slidably connected with sleeves. The bottom end of the sleeve is fixedly connected with a support plate.

[0013] Preferably, a buffer spring is fixedly connected to the inner wall of the sleeve. The top end of the buffer spring is fixedly connected with the bottom end of the sliding rod. The bottom end of the buffer spring is fixedly connected with the inner bottom wall of the sleeve. A plurality of propellers are rotatably connected to the surface of the UAV housing.

[0014] The beneficial effects of the present invention are as follows:

[0015] When the surface of the inspection probe becomes blurred due to flying in the hazy air for a long time, by driving the movement disc to rotate, the piston plate reciprocates in the water tank. During this process, the pumping and draining operations of the water tank below the partition are realized. The discharged clean water is sent into the annular water outlet pipe through the drain pipe and evenly discharged and flows onto the surface of the inspection probe. During this process, the driving disc rotates to drive a plurality of first teeth and second teeth to rotate. Under the action of the second teeth and the first teeth, the gear drives the driving shaft and the V-shaped cleaning brush to rotate reciprocally in both directions. When the V-shaped cleaning brush moves, it rubs against the surface of the inspection probe to clean the surface of the inspection probe. The advantage of this is that when the drone is on patrol and encounters hazy or sandstorm weather, it can effectively remove the dust attached to the surface of the inspection probe and make its imaging clearer.

[0025] By setting a water tank 3, clean water for cleaning the surface of the inspection probe 2 is stored. By setting the inspection probe 2, visual imaging is performed when the UAV shell 1 is flying. A wireless module is installed inside the inspection probe 2, and the captured data can be transmitted to the outside world through wireless signals. By setting a U-shaped plate 4, the motor 5 is installed and supported to prevent the UAV shell 1 from being damaged during the shaking of the flight. By setting a drive shaft 13, the V-shaped cleaning brush 16 is driven to rotate. By setting the V-shaped cleaning brush 16, the surface of the V-shaped cleaning brush 16 is in friction contact with the surface of the inspection probe 2, and the surface of the inspection probe 2 is frictionally cleaned. By setting an annular water outlet pipe 17, clean water is evenly sprayed on the surface of the inspection probe 2. By setting a cleaning mechanism, the surface of the inspection probe 2 is better cleaned through the cooperation of the V-shaped cleaning brush 16 and the clean water.

[0026] In the present invention, reference Figure 2, the cleaning mechanism includes a motor 5 fixedly connected to the surface of the U-shaped plate 4. The output end of the motor 5 is fixedly connected with a moving disk 6. A partition 8 is fixedly connected to the inner wall of the water tank 3. A piston plate 24 is slidably connected to the inner wall of the water tank 3. One end of the piston plate 24 penetrates through the surface of the U-shaped plate 4. The piston plate 24 is adapted to the space formed by the water tank 3 and the partition 8.

[0027] By arranging the motor 5, its output end drives the moving disk 6 to rotate together with the driving wheel 12. By arranging the partition 8, the space in the water tank 3 is divided into two independent spaces. By arranging the piston plate 24, the piston plate 24 drives the water flow above the partition 8 in the water tank 3 to flow, achieving the effect of supplying and draining water in the water tank 3 below the partition 8.

[0028] In the present invention, referring to Figure 3 and Figure 5 , one end of the piston plate 24 close to the moving disk 6 is fixedly connected with a C-shaped rod 7. A pair of hemispherical bumps 26 are fixedly connected to the surface of the C-shaped rod 7. A wavy annular groove 28 is formed on the surface of the moving disk 6. The hemispherical bumps 26 are installed inside the wavy annular groove 28 and are adapted to it. The same drain pipe 18 is fixedly connected to the inner walls of the water tank 3 and the annular water outlet pipe 17.

[0029] By arranging the C-shaped rod 7, a pair of hemispherical bumps 26 are installed and positioned. By arranging the wavy annular groove 28, under the action of the rotating wavy annular groove 28, the pair of hemispherical bumps 26 drive the whole C-shaped rod 7 and the piston plate 24 to slide back and forth. By arranging the drain pipe 18, the liquid in the water tank 3 is sent into the annular water outlet pipe 17 through the drain pipe 18.

[0030] In the present invention, referring to Figure 2 , a first one-way valve 9 is installed on the inner wall of the partition 8. An air inlet pipe 10 is fixedly connected to the inner top wall of the water tank 3. A second one-way valve 11 is installed on the surface of the air inlet pipe 10.

[0031] By arranging the first one-way valve 9, the liquid below the partition 8 is prevented from flowing back to the upper part of the partition 8. By arranging the second one-way valve 11, the stability of air supplement entering the water tank 3 is maintained.

[0032] In the present invention, referring to Figure 3 and Figure 4 , one end of the drive shaft 13 away from the V-shaped cleaning brush 16 is fixedly connected with a gear 23. A limiting plate 14 is fixedly connected to the inner bottom wall of the UAV housing 1. A rotating shaft 27 is rotatably connected to the inner wall of the limiting plate 14. One end of the rotating shaft 27 is fixedly connected with a driving disk 20. A plurality of first teeth 21 and second teeth 22 are fixedly connected to the inner surface of the driving disk 20. The first teeth 21 are engaged with the gear 23, and the second teeth 22 are engaged with the gear 23.

[0033] By setting the limit plate 14, the rotation of the rotating shaft 27 is kept stable. By setting the driving disk 20, multiple first teeth 21 and second teeth 22 are driven to rotate. By setting the first teeth 21 to mesh with the gear 23 and the second teeth 22 to mesh with the gear 23, when the driving disk 20 rotates, the gear 23 is driven to reciprocate forward and reverse, and then the V-shaped cleaning brush 16 is driven to perform frictional cleaning on the surface of the inspection probe 2.

[0034] In the present invention, referring to Figure 2 and Figure 3 , a driving wheel 12 is fixedly connected to the surface of the output end of the motor 5, a driven wheel 19 is fixedly connected to one end of the rotating shaft 27, and the same belt 15 is sleeved and tensioned on the surfaces of the driving wheel 12 and the driven wheel 19. An avoidance hole 25 is formed in the surface of the U-shaped plate 4, and the belt 15 is installed inside the avoidance hole 25.

[0035] By setting the driving wheel 12, the driving wheel 12 rotates to drive the driven wheel 19 to rotate through the belt 15. By setting the avoidance hole 25, a safe avoidance space is given to the belt 15.

[0036] In the present invention, referring to Figure 6 , a plurality of sliding rods 32 are fixedly connected to the lower surface of the UAV housing 1, and sleeves 30 are slidably connected to the surfaces of the plurality of sliding rods 32. A support plate 29 is fixedly connected to the bottom end of the sleeve 30.

[0037] By setting the sleeve 30, the sliding of the sliding rod 32 is kept stable. By setting the support plate 29, when the UAV housing 1 is placed on a horizontal plane, the UAV housing 1 is balanced and supported to keep the balance and stability of the UAV housing 1 when not in use. By setting the sleeve 30, a buffer spring 31 is installed and protected to prevent it from detaching from the inside of the sleeve 30.

[0038] In the present invention, referring to Figure 6 , a buffer spring 31 is fixedly connected to the inner wall of the sleeve 30. The top end of the buffer spring 31 is fixedly connected to the bottom end of the sliding rod 32, and the bottom end of the buffer spring 31 is fixedly connected to the inner bottom wall of the sleeve 30. A plurality of propellers 33 are rotatably connected to the surface of the UAV housing 1.

[0039] By setting the buffer spring 31, when the UAV housing 1 falls, after the lower surface of the support plate 29 contacts the ground, the impact is reduced through the buffer spring 31 to protect the whole UAV housing 1. By setting a plurality of propellers 33, the plurality of propellers 33 are controlled by a PLC to rotate synchronously to keep the whole UAV housing 1 balanced and stable during aerial inspection.

[0040] Working principle: During use, through an external controller, multiple propellers 33 are started to rotate synchronously through electrical signals, driving the overall height of the drone housing 1 to rise for flight inspections, and observing the ground conditions through the inspection probe 2. When encountering hazy weather and during long-term flight operations, the dust in the haze will adhere to the surface of the inspection probe 2, resulting in unclear imaging when the inspection probe 2 takes pictures. To avoid affecting the inspection and monitoring of the drone, at this time, the surface of the inspection probe 2 needs to be cleaned. Through an external wireless controller, the motor 5 is started through a wireless signal. The output end of the motor 5 drives the driving wheel 12 and the moving disk 6 to rotate together. After the moving disk 6 rotates, since a pair of hemispherical protrusions 26 are installed inside the wavy annular groove 28, through the pair of hemispherical protrusions 26, the C-shaped rod 7 and the piston plate 24 reciprocate in the water tank 3. When the piston plate 24 moves towards the moving disk 6, the cleaning water above the partition 8 is pumped through the first one-way valve 9 to the lower part of the partition 8 in the water tank 3. At this time, the outside air is pumped into the water tank 3 through the air inlet pipe 10 for replenishment, and the second one-way valve 11 ensures the one-way flow of air into the water tank 3 to maintain the stable air pressure in the water tank 3. When the piston plate 24 moves away from the moving disk 6, the cleaning water below the partition 8 is squeezed and conveyed into the drain pipe 18 through the action of the thrust. At this time, the first one-way valve 9 prevents the liquid from flowing back and flows into the annular water outlet pipe 17 and is evenly discharged onto the surface of the inspection probe 2. In this process, the driving wheel 12 rotates to drive the driven wheel 19 to rotate through the belt 15. The driven wheel 19 drives the driving disk 20 to rotate through the rotating shaft 27. The driving disk 20 rotates to drive multiple first teeth 21 and second teeth 22 to rotate. Since the first teeth 21 mesh with the gear 23 and the second teeth 22 mesh with the gear 23, the gear 23 drives the driving shaft 13 to rotate forward and backward under the action of the second teeth 22 and the first teeth 21. The driving shaft 13 drives the V-shaped cleaning brush 16 to rotate forward and backward. When the V-shaped cleaning brush 16 moves, it rubs against the surface of the inspection probe 2. With the cooperation of the cleaning water, the surface of the inspection probe 2 is cleaned, better removing the dust adhering to the surface of the inspection probe 2 and making its imaging clearer. When the drone housing 1 is descending, after the lower surface of the support plate 29 contacts the upper surface of the ground, it drives the sleeve 30 to slide on the surface of the sliding rod 32. At this time, the compression buffer spring 31 becomes shorter for landing buffer protection. With the above structure, the surface of the inspection probe 2 can be better cleaned.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
