Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an inspection unmanned aerial vehicle. Background Art

[0002] ‌An inspection unmanned aerial vehicle is a device that uses unmanned aerial vehicle technology for regular or irregular inspections. It is mainly used for efficient and safe inspections of specific areas or facilities. Compared with traditional manual inspections, inspection unmanned aerial vehicles have advantages such as high speed, wide coverage, and low risk. They can carry devices such as high-definition cameras, infrared thermal imagers, and multi-spectral sensors to conduct detailed observations and data collection on ground buildings, infrastructure, etc.; In order to improve the service life of the inspection unmanned aerial vehicle, corresponding fault detection devices are installed inside the inspection unmanned aerial vehicle. That is, when an abnormality occurs in the working circuit inside the inspection unmanned aerial vehicle, an electrical signal will be sent through the fault detection device, thereby reminding the corresponding staff to take corresponding measures. The overall degree of intelligence is relatively high. However, in the actual working process, the traditional fault detection device can only send an electrical signal and has no other processing measures. Due to the relatively harsh working environment of the inspection unmanned aerial vehicle, when the inspection unmanned aerial vehicle fails, there is no protection measure, resulting in a greatly increased probability of damage to the inspection unmanned aerial vehicle. Moreover, when the inspection unmanned aerial vehicle fails, it is not known whether the inspection unmanned aerial vehicle fails due to a fault in its internal structure or due to an external collision of the inspection unmanned aerial vehicle. As a result, when a failure occurs, the staff can only adopt a relatively conservative method for processing. Also, if the inspection unmanned aerial vehicle fails due to external reasons, it means that the environment outside the inspection unmanned aerial vehicle is relatively harsh. At this time, the high-definition camera installed outside the inspection unmanned aerial vehicle cannot achieve a good shooting effect. Finally, since the inspection unmanned aerial vehicle will install corresponding devices outside according to the actual working conditions during use, when the inspection unmanned aerial vehicle fails, there is also no protection device for the devices installed outside the inspection unmanned aerial vehicle. Therefore, an inspection unmanned aerial vehicle is provided. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies existing in the prior art and to propose an inspection unmanned aerial vehicle.

[0004] The present invention adopts the following technical solutions: An inspection drone, comprising a drone body and a detection body fixedly installed inside the drone body. A transmitter is fixedly installed on the upper side of the drone body. A camera is installed on the front side of the drone. A protection component is installed outside the drone body. The protection component includes two telescopic protection frames. The two telescopic protection frames are symmetrically distributed on both sides of the drone body. Each telescopic protection frame is composed of multiple protection rods. Two sliding grooves are symmetrically formed on the side wall of the drone body. A slide plate corresponding to the protection rod in terms of quantity and position is slidably connected in each sliding groove, and the protection rod is fixedly connected to the corresponding slide plate. A control component for controlling the expansion and contraction of the two telescopic protection frames is also installed on the side wall of the drone body.

[0005] Preferably, the control component includes a motor and a second connecting plate slidably connected to each slide plate. The motor is fixedly connected to the drone body. The second connecting plates on the same side form a group. A first sliding groove is also formed on the side wall of the drone body. A plurality of first connecting rods are slidably connected in the first sliding groove. The plurality of first connecting rods are arranged in a row and are located between the two groups of second connecting plates. One of the first connecting rods is fixedly connected to the first sliding groove, and the other first connecting rods are slidably connected to the first sliding groove. A second connecting rod is fixedly connected to the side wall of each second connecting plate. A first connecting plate is rotatably connected between the plurality of second connecting rods and the first connecting rods. The plurality of first connecting plates are arranged in a cross manner. The output shaft of the motor is fixedly connected to a threaded rod, and a threaded cylinder is threadedly sleeved on the outer side of the threaded rod. The threaded cylinder is fixedly connected to one of the first connecting rods, and the first connecting rod fixedly connected to the threaded cylinder is slidably connected to the first sliding groove.

[0006] Preferably, a detection component is installed on the outer side of the protection rod. The detection component includes two third connecting plates fixedly installed on the side wall of the protection rod. A third connecting rod is rotatably connected between the two third connecting plates. A first gear is fixedly connected to the outer side of the third connecting rod. A plurality of first racks are evenly fixedly connected to both sides of the drone body. The first gear is meshed with the first rack. A second gear is also fixedly connected to the outer side of the third connecting rod. A fixed frame is fixedly connected to the outer side of the protection rod. A square tube is slidably connected in the fixed frame. A second rack is fixedly connected to the side wall of the square tube. The second gear is meshed with the second rack. A fourth connecting plate is fixedly connected to the outer side of the square tube. A second spring is fixedly connected between the fourth connecting plate and the fixed frame. A square rod is also slidably connected in the square tube. A first spring is fixedly connected between the square rod and the bottom of the square tube. A pressure sensor is fixedly connected between the square rod and the bottom of the square tube. A detection plate is fixedly connected to the outer side of the slide plate.

[0007] Preferably, brushes are fixedly connected to both side walls of the detection plate.

[0008] Preferably, a positioning component is installed outside the UAV body. The positioning component includes a fifth connecting plate slidably installed in the protective rod. Two third chutes are symmetrically formed outside the UAV body. A sixth connecting plate is slidably connected in the two third chutes. A second trapezoidal plate is fixedly connected to the outside of the sixth connecting plate. A first trapezoidal plate is fixedly connected to the side wall of the second trapezoidal plate. A stopper is fixedly connected to the side wall of the fifth connecting plate. A plurality of seventh connecting plates are formed outside the square cylinder.

[0009] Preferably, the inclined surfaces of the first trapezoidal plate and the second trapezoidal plate are both smooth.

[0010] Preferably, two supporting feet are fixedly installed on the lower side of the UAV body. Anti-slip rubber sleeves are sleeved on the outside of the two supporting feet.

[0011] Preferably, a plurality of protrusions are installed on the outside of the protective rod.

[0012] The beneficial effects of the present invention are as follows: 1. First, when the inspection UAV fails, the detection body will send an electrical signal to the transmitter. The transmitter transmits the received electrical signal to the control center (such as a computer, mobile phone, etc.). Then, the staff can perform corresponding regulation through the control center. During this process, the detection body will also start the motor through the controller. While the motor drives the telescopic protection frame to move, it will also cause the telescopic protection frame to unfold, thereby forming a protection operation for the UAV body, especially the head of the UAV body. And it can also protect the camera and other devices installed outside the UAV body, reducing damage to devices such as the UAV body and the camera. 2. Second, during the movement of the telescopic protection frame, when the first gear meshes with the first rack, it will cause the detection plate to move. When the detection plate abuts against the UAV body, under the blocking action of the UAV body, the detection plate stops moving, and the pressure sensor emits a corresponding electrical signal. According to the magnitude of the electrical signal emitted by the pressure sensor, it is possible to know whether a failure has occurred outside the UAV body, and thus the staff can make an accurate judgment and take appropriate measures. 3. Moreover, during the movement of the telescopic protection frame, when the protective rod therein moves to the outside of the camera, since there is no obstruction from the UAV body, it will cause the detection plate to move towards the camera. Since there are brushes on both sides of the detection plate, under the action of the brushes, a cleaning operation can be formed on the surface of the camera, achieving multiple benefits at once. 4. Finally, when the threaded cylinder moves a relatively long distance, the motor stops moving. In the last stage of the movement of the threaded cylinder, the square cylinder and the protective rod will be in a fixed connection state. At this time, under the action of the detection plate, secondary protection operations can be formed for the UAV body and the equipment installed on the front side of the UAV body. Moreover, the pressure sensor emits a constant electrical signal. Then, when the UAV body continues to work, if the electrical signal emitted by the pressure sensor changes, it indicates that the outside of the UAV body or the equipment installed on the front side of the UAV body has been damaged and corresponding treatment is required.

Detailed implementation

[0015] Refer to Figures 1-13 , an inspection drone, comprising a drone body 1 and a detection body 2 fixedly installed inside the drone body 1. A transmitter 3 is fixedly installed on the upper side of the drone body 1. A camera 4 is installed on the front side of the drone. Two support feet are fixedly installed on the outer side of the drone body 1, and anti-slip rubber sleeves are sleeved on the outer sides of the two support feet; First, during the use of the inspection drone, corresponding devices (such as infrared thermal imagers, multispectral sensors, etc.) can be installed on the front side of the inspection drone. With the cooperation of the camera 4, detailed observation and data collection can be carried out on ground buildings, basic equipment, etc. Then, the transmitter 3, that is, a radio transmitter, generates and modulates radio frequency current and transmits radio waves. And the transmitter 3 is electrically connected to the detection body 2. When the detection body 2 detects a fault in the internal circuit of the drone body 1, the detection body 2 will send an electrical signal to the transmitter 3, and the transmitter 3 transmits the received electrical signal to the control center (such as a computer, a mobile phone, etc.), and then the staff can carry out corresponding regulation through the control center. The above operations are all prior arts and will not be elaborated further; A protection component 5 is installed outside the UAV body 1. The protection component 5 includes two telescopic protection frames, which are symmetrically distributed on both sides of the UAV body 1. Each telescopic protection frame is composed of a plurality of protection rods 13. Two sliding grooves 11 are symmetrically formed on the side wall of the UAV body 1. A skateboard 12 with the same number and position as the protection rod 13 is slidably connected in each sliding groove 11, and the protection rod 13 is fixedly connected to the corresponding skateboard 12. A control component for controlling the expansion and contraction of the two telescopic protection frames is also installed on the side wall of the UAV body 1. The control component includes a motor 6 and a second connecting plate 14 slidably connected to each skateboard 12. The motor 6 is fixedly connected to the UAV body 1. The second connecting plates 14 on the same side are taken as a group. A first sliding groove 9 is also formed on the side wall of the UAV body 1. A plurality of first connecting rods 10 are slidably connected in the first sliding groove 9. The plurality of first connecting rods 10 are arranged in a row and are located between the two groups of second connecting plates 14. One of the first connecting rods 10 is fixedly connected to the first sliding groove 9, and the other first connecting rods 10 are slidably connected to the first sliding groove 9. A second connecting rod 15 is fixedly connected to the side wall of each second connecting plate 14. A first connecting plate 16 is rotatably connected between the plurality of second connecting rods 15 and the first connecting rods 10. The plurality of first connecting plates 16 are arranged in a cross shape. The output shaft of the motor 6 is fixedly connected to a threaded rod 7, and a threaded sleeve 8 is threadedly sleeved on the outer side of the threaded rod 7. The threaded sleeve 8 is fixedly connected to one of the first connecting rods 10, and the first connecting rod 10 fixedly connected to the threaded sleeve 8 is slidably connected to the first sliding groove 9. A plurality of protrusions are installed on the outer side of the protection rod 13 to improve the protection effect; First, the motor 6 and the detection body 2 are electrically connected. When the detection body 2 detects a fault inside the UAV body 1, the electrical signal sent by the detection body 2 will start the motor 6 through the controller, that is, the controller, the detection body 2 and the built-in power supply of the UAV body 1 form a closed circuit, and this closed circuit is only controlled by the detection body 2. Secondly, the first connecting rod 10 closest to the motor 6 is fixedly connected to the first sliding groove 9, and one of the other first connecting rods 10 is fixedly connected to the threaded sleeve 8. Then, the connection situation of the plurality of first connecting plates 16 is as Figure 7As shown, the structure composed of multiple first connecting plates 16, first connecting rods 10, and second connecting rods 15 is similar to the telescopic scissor structure in real life. Then, when the motor 6 drives the threaded rod 7 to rotate, since the threaded barrel 8 and the threaded rod 7 are threadedly connected, the threaded barrel 8 is fixedly connected to the first connecting rod 10 farthest from the motor 6, and the other first connecting rods 10 are slidably connected to the first sliding groove 9. Therefore, the rotating threaded rod 7 will drive the threaded barrel 8 to move, thereby causing the distance between each first connecting rod 10 to gradually increase. Then, under the action of the first connecting plate 16, the second connecting rod 15 is caused to move. The second connecting rod 15 drives the sliding plate 12 to move through the second connecting plate 14, and the sliding plate 12 drives the protection rod 13 to move. While the protection rod 13 moves, the distance between two adjacent protection rods 13 also gradually increases, so that the telescopic protection frame is completed and unfolded, thereby forming a protection operation for the UAV body 1, especially the head of the UAV body 1. In addition, it can also protect the camera 4 and other devices installed on the outside of the UAV body 1, reducing the risk of the UAV body 1, the camera 4 and other devices being damaged again. During the above working process, the second connecting plate 14 is always slidably connected to the sliding plate 12.

[0016] A detection component is installed on the outer side of the protection rod 13. The detection component includes two third connecting plates 17 fixedly installed on the side wall of the protection rod 13. The two third connecting plates 17 are jointly rotatably connected to a third connecting rod 18. A first gear 19 is fixedly connected to the outer side of the third connecting rod 18. A plurality of first racks 20 are evenly and fixedly connected to both sides of the UAV body 1. The first gear 19 meshes with the first rack 20. A second gear 21 is also fixedly connected to the outer side of the third connecting rod 18. A fixed frame 23 is fixedly connected to the outer side of the protection rod 13. A square tube 24 is slidably connected in the fixed frame 23. A second rack 22 is fixedly connected to the side wall of the square tube 24. The second gear 21 meshes with the second rack 22. A fourth connecting plate 29 is fixedly connected to the outer side of the square tube 24. A second spring 30 is fixedly connected between the fourth connecting plate 29 and the fixed frame 23. A square rod 25 is also slidably connected in the square tube 24. A first spring 26 is fixedly connected between the square rod 25 and the bottom of the square tube 24. A pressure sensor 27 is fixedly connected between the square rod 25 and the bottom of the square tube 24. A detection plate 28 is fixedly connected to the outer side of the sliding plate 12; First, the pressure sensor 27 is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules. Second, in the initial state, the first gear 19 is not engaged with the first rack 20. Then, when a failure occurs in the UAV body 1 and the protection rod 13 starts to move, the protection rod 13 drives the third connecting rod 18 to move through the third connecting plate 17. The third connecting rod 18 drives the first gear 19 and the second gear 21 to move. During the process of the third connecting rod 18 following the movement of the protection rod 13, when the first gear 19 is engaged with the first rack 20, based on Figure 5 and Figure 8 the view direction, when the telescopic protection frame unfolds to protect the UAV body 1, the protection rod 13 moves to the left. Since the first rack 20 is in a fixed state, it will cause the first gear 19 to rotate counterclockwise. The first gear 19 drives the third connecting rod 18 to rotate, and the third connecting rod 18 drives the second gear 21 to rotate counterclockwise. The second gear 21 drives the engaged second rack 22 to move downward. The second rack 22 drives the square tube 24 to move downward. The square tube 24 drives the fourth connecting plate 29 to move downward. The fourth connecting plate 29 compresses the second spring 30. At the same time, the square tube 24 also drives the square rod 25 to move downward through the first spring 26. The square rod 25 drives the detection plate 28 to move downward. When the detection plate 28 abuts against the UAV body 1, under the blocking effect of the UAV body 1, the detection plate 28 stops moving. As a result, while compressing the first spring 26, the pressure sensor 27 emits a corresponding electrical signal. Due to the special shape of the UAV body 1, that is, the UAV body 1 is symmetrically arranged, it is possible to know whether a failure has occurred outside the UAV body 1 according to the magnitude of the electrical signal emitted by the pressure sensor 27. When there is a large difference in the electrical signals emitted by the pressure sensors 27 on both sides, it indicates that the outside of the detection plate 28 is damaged at this time. When the electrical signal emitted by the pressure sensor 27 on the same side is too small, it indicates that the outside of the UAV body 1 is damaged. Thus, it is possible to make a judgment based on the electrical signal emitted by the pressure sensor 27, enabling the staff to adopt appropriate handling operations.

[0017] Both side walls of the detection plate 28 are fixedly connected with brushes; Moreover, when the protection rod 13 moves to the outside of the camera 4, since it is not blocked by the UAV body 1, it will cause the detection plate 28 to move towards the camera 4. Due to the brushes on both sides of the detection plate 28, under the action of the brushes, a cleaning operation can be performed on the surface of the camera 4, achieving multiple purposes at once.

[0018] A positioning component is installed outside the UAV body 1. The positioning component includes a fifth connecting plate 32 slidably installed in the protective rod 13. Two third sliding grooves 31 are symmetrically formed on the outside of the UAV body 1. A sixth connecting plate 33 is slidably connected in the two third sliding grooves 31. A second trapezoidal plate 35 is fixedly connected to the outside of the sixth connecting plate 33. A first trapezoidal plate 34 is fixedly connected to the side wall of the second trapezoidal plate 35. A stopper 36 is fixedly connected to the side wall of the fifth connecting plate 32. A plurality of seventh connecting plates 37 are formed on the outside of the square cylinder 24. The inclined surfaces of the first trapezoidal plate 34 and the second trapezoidal plate 35 are both smooth. The protective rod 13 and the fixed frame 23 are provided with sliding openings for the stopper 36 to slide through. First, in the initial state, although the first trapezoidal plate 34 abuts against the fifth connecting plate 32, there is no force between the first trapezoidal plate 34 and the fifth connecting plate 32. Second, when the protective rod 13 starts to move, the stopper 36 is located below the seventh connecting plate 37 and will not form an obstructive effect on the seventh connecting plate 37 (based on Figure 13 the perspective of...). Then, during the movement of the threaded cylinder 8 and the protective rod 13, when the threaded cylinder 8 abuts against the inclined surface of the second trapezoidal plate 35, under the restrictive action of the third sliding groove 31 and the sixth connecting plate 33, based on Figure 12 the direction of..., it will cause the two second trapezoidal plates 35 to move away from each other. The second trapezoidal plate 35 drives the first trapezoidal plate 34 to move away from each other. When the first trapezoidal plate 34 abuts against the fifth connecting plate 32, it will drive the fifth connecting plate 32 to move upward. The fifth connecting plate 32 drives the stopper 36 to move upward. The stopper 36 can move between the two seventh connecting plates 37, which will obstruct the movement of the seventh connecting plate 37 and the square cylinder 24, and complete the clamping and fixing of the telescopic protection frame in this state, making it stable in this state. And this state is the maximum degree of expansion of the telescopic protection frame. At this time, the motor 6 is turned off. Since the volume of the equipment installed on the front side of the UAV body 1 is not larger than the volume of the entire UAV body 1, when some of the protective rods 13 cross the shell of the UAV body 1, the detection plates 28 on their side walls will not be blocked by the side wall of the UAV body 1. Therefore, the detection plates 28 on the left and right sides will abut against the equipment installed on the front side of the UAV body 1, thereby providing secondary protection for the equipment installed on the front side of the UAV body 1. Moreover, the pressure sensor 27 emits a constant electrical signal. Then, when the UAV body 1 continues to work, when the electrical signal emitted by the pressure sensor 27 changes, it means that the outside of the UAV body 1 or the equipment installed on the front side of the UAV body 1 has been damaged and corresponding treatment is required.

[0019] In the present invention, when the detection body 2 detects a fault in the internal circuit of the UAV body 1, the detection body 2 sends an electrical signal to the transmitter 3, and the transmitter 3 transmits the received electrical signal to the control center (such as a computer, a mobile phone, etc.). Then, the staff can perform corresponding regulation through the control center. The above operations are all prior arts and will not be elaborated further; When the detection body 2 detects a fault inside the UAV body 1, the electrical signal sent by the detection body 2 will start the motor 6 through the controller, and then drive the threaded rod 7 to rotate. The rotating threaded rod 7 will drive the threaded barrel 8 to move, thereby causing the distance between each first connecting rod 10 to gradually increase. Then, under the action of the first connecting plate 16, the second connecting rod 15 will move. The second connecting rod 15 drives the slide plate 12 to move through the second connecting plate 14, and the slide plate 12 drives the protection rod 13 to move. While the protection rod 13 is moving, the distance between two adjacent protection rods 13 also gradually increases, so that the telescopic protection frame is completed and unfolded, thus forming a protection operation for the UAV body 1, especially the head of the UAV body 1. Moreover, it can also protect the camera 4 and other devices installed on the outer side of the UAV body 1, reducing the chance of the UAV body 1, the camera 4 and other devices being damaged again. During the above working process, the second connecting plate 14 is always slidably connected to the slide plate 12; When a fault occurs in the UAV body 1 and the protection rod 13 starts to move, the protection rod 13 drives the third connecting rod 18 to move through the third connecting plate 17, and the third connecting rod 18 drives the first gear 19 and the second gear 21 to move. During the process of the third connecting rod 18 moving following the protection rod 13, when the first gear 19 meshes with the first rack 20, Figure 5 and Figure 8Based on the view direction, when the telescopic protection frame expands to protect the UAV body 1, the protection rod 13 moves to the left. Since the first rack 20 is in a fixed state, the first gear 19 will rotate counterclockwise, the first gear 19 drives the third connecting rod 18 to rotate, the third connecting rod 18 drives the second gear 21 to rotate counterclockwise, the second gear 21 drives the engaged second rack 22 to move downward, the second rack 22 drives the square cylinder 24 to move downward, the square cylinder 24 drives the fourth connecting plate 29 to move downward, and the fourth connecting plate 29 compresses the second spring 30. At the same time, the square cylinder 24 also drives the square rod 25 to move downward through the first spring 26, the square rod 25 drives the detection plate 28 to move downward. When the detection plate 28 abuts against the UAV body 1, under the blocking effect of the UAV body 1, the detection plate 28 stops moving. As a result, while compressing the first spring 26, the pressure sensor 27 emits a corresponding electrical signal. Due to the special shape of the UAV body 1, that is, the UAV body 1 is symmetrically arranged, it is possible to know whether a fault has occurred outside the UAV body 1 according to the magnitude of the electrical signal emitted by the pressure sensor 27. When there is a large difference in the electrical signals emitted by the pressure sensors 27 on both sides, it indicates that the outside of the detection plate 28 is damaged at this time. When the electrical signal emitted by the pressure sensor 27 on the same side is too small, it indicates that the outside of the UAV body 1 is damaged. Therefore, it is possible to make a judgment based on the electrical signal emitted by the pressure sensor 27, enabling the staff to adopt appropriate handling operations; When the protection rod 13 moves to the outside of the camera 4, since there is no obstruction from the UAV body 1, it will cause the detection plate 28 to move towards the camera 4. Since there are brushes on both sides of the detection plate 28, under the action of the brushes, a cleaning operation on the surface of the camera 4 can be formed, achieving multiple benefits at once; During the movement of the threaded cylinder 8 and the protection rod 13, when the threaded cylinder 8 abuts against the inclined surface of the second trapezoidal plate 35, under the limiting action of the third chute 31 and the sixth connecting plate 33, Figure 12Based on the direction, it will cause the two second trapezoidal plates 35 to move away from each other. The second trapezoidal plates 35 drive the first trapezoidal plates 34 to move away from each other. When the first trapezoidal plates 34 abut against the fifth connecting plates 32, it will drive the fifth connecting plates 32 to move upward. The fifth connecting plates 32 drive the stoppers 36 to move upward. The stoppers 36 can move between the two seventh connecting plates 37, which will hinder the movement of the seventh connecting plates 37 and the square cylinder 24, and complete the clamping and fixing of the telescopic protection frame in this state, making it stable in this state. And this state is the maximum degree of expansion of the telescopic protection frame. At this time, turn off the motor 6. Since the volume of the equipment installed on the front side of the UAV body 1 is not larger than the volume of the entire UAV body 1, when some of the protection rods 13 cross the shell of the UAV body 1, the detection plates 28 on their side walls will not be blocked by the side wall of the UAV body 1. Therefore, the detection plates 28 on the left and right sides will abut against the equipment installed on the front side of the UAV body 1, so as to provide secondary protection for the equipment installed on the front side of the UAV body 1. Moreover, the pressure sensor 27 emits a constant electrical signal. Then when the UAV body 1 continues to work, when the electrical signal emitted by the pressure sensor 27 changes, it means that the outside of the UAV body 1 or the equipment installed on the front side of the UAV body 1 is damaged and corresponding treatment is required.
