Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle inspection, and in particular to a converter station unmanned aerial vehicle ultraviolet inspection device and an inspection method thereof. Background Art

[0002] In modern power systems, converter stations, as core hubs, undertake the key task of converting electric energy at different voltage levels. It enables efficient transmission of electric energy between different voltage levels, realizes the stable supply of electricity from power stations to end users, and plays an indispensable role in ensuring the normal operation of social production and life. During the operation of converter stations, regular inspection of equipment in the station is an important means to ensure its safe and stable operation. Since there are a large number of high-voltage equipment in converter stations and they are in a high-voltage and strong electromagnetic environment, traditional manual inspection methods face many challenges. On the one hand, the personal safety of workers working in such an environment will be greatly threatened, and long-term exposure to high-voltage electric fields and strong electromagnetic radiation may cause health problems; on the other hand, manual inspection efficiency is low, and it is difficult to conduct comprehensive and timely inspections of large and complex converter station equipment, and the accuracy of manual inspections is easily affected by subjective factors, such as fatigue and experience differences.

[0003] With the rapid development of science and technology, drone technology has gradually matured and has been widely used in the field of power inspection. With its advantages of flexibility, mobility and remote operation, drones have effectively solved some of the problems of manual inspection, greatly improved inspection efficiency and reduced personnel safety risks. However, there are still some problems that need to be solved in the existing drone inspection technology. First, most drones used for converter station inspection are only equipped with ordinary cameras or thermal imagers, and the detection means are relatively simple. They can only obtain the appearance and temperature information of the equipment, and cannot effectively detect potential electrical faults of high-voltage equipment. For example, it is difficult to find early fault hazards such as partial discharge of equipment, which greatly reduces the comprehensiveness and accuracy of the inspection. Second, the layout of equipment in the converter station is complex and the space is limited. If the drone is not operated carefully during the inspection process, it is very easy to collide with the equipment in the station. Once a collision occurs, it will not only cause damage to the drone and increase maintenance costs, but also may cause damage to the equipment in the station, causing serious power accidents and affecting the stability of power supply.

[0004] In order to overcome the shortcomings of the above-mentioned existing technologies and meet the growing demand for efficient, accurate and safe inspections of converter stations, it is urgent to develop a converter station drone ultraviolet inspection device and an inspection method thereof with more powerful detection functions and higher safety. Summary of the invention

[0005] The purpose of the present invention is to provide a converter station drone ultraviolet inspection device and an inspection method thereof, so as to solve the problems of limited detection items and easy collision in the application of existing drone inspections in converter stations, realize more efficient, accurate and safe inspection operations, and ensure the stable operation of the converter station.

[0006] The present invention is achieved through the following technical solutions:

[0007] A converter station UAV ultraviolet inspection device, comprising:

[0008] A fuselage, wherein the outer wall of the fuselage is connected with a wing, a propeller is arranged at the outer end of the wing, and a protective cover is arranged at the outer end of the propeller;

[0009] A shooting assembly, wherein an ultraviolet imager is arranged inside the shooting assembly, and the shooting assembly is connected to the lower end of the body through a driving assembly;

[0010] A protection component, wherein a cavity for accommodating the shooting component is provided in the middle of the protection component, the top of the cavity is connected to the output end of the driving component, and the outer side wall of the protection component is rotatably connected to multiple groups of supporting components through a transmission component;

[0011] When the driving assembly drives the shooting assembly and the protection assembly to rotate synchronously, the plurality of support assemblies are driven by the transmission assembly to expand or collapse along the axis of the machine body.

[0012] In this scheme, the fuselage, wings, propellers and protective cover constitute the flight infrastructure of the UAV. The driving component can make the shooting component rotate in a circle, which enables the shooting component to achieve multi-angle shooting without adjusting the orientation of the fuselage. An ultraviolet imager is installed inside the shooting component. On the basis of conventional shooting, local discharge detection is performed on the high-voltage equipment in the converter station to achieve effective detection of potential electrical faults. At the same time, the protective component not only provides protection for the shooting component, but is also connected to the support component through the transmission component. When the driving component drives the shooting component and the protective component to rotate synchronously, it can control the support component to expand or retract, and play a protective role in buffering the collision force when the equipment is close to the detection equipment, so that the UAV has high protection, high detection accuracy and easy operation in the inspection of the converter station.

[0013] As a further optimization of the patrol device, the shooting assembly includes a rotating seat, a connecting seat, an electric control rotating shaft and a camera;

[0014] One end of the rotating seat is connected to the output end of the driving component, and the other end of the rotating seat is connected to the camera through the connecting seat. The electric-controlled rotating shaft is arranged inside the connecting seat, and the electric-controlled rotating shaft drives the camera to pitch and rotate.

[0015] In this solution, the electrically controlled shaft cooperates with the rotating seat to drive the camera to rotate in a circle, greatly expanding the camera's shooting angle range. This allows the drone to achieve comprehensive shooting of equipment at different locations and heights in the converter station without having to significantly adjust the body position during the inspection process, effectively improving the flexibility and comprehensiveness of shooting, thereby enhancing the efficiency and quality of the inspection work.

[0016] As a further optimization of the patrol device, the protection assembly includes a bearing seat, a tempered glass layer, and a connecting rod;

[0017] One end of the bearing seat is connected to the lower end of the body, and the other end of the bearing seat is connected to the tempered glass layer through a bearing;

[0018] A cavity for accommodating the shooting assembly is formed in the middle of the tempered glass layer, and the connecting rod is arranged inside the cavity, and two ends of the connecting rod are respectively connected to the output end of the driving assembly and the tempered glass layer.

[0019] In this solution, the tempered glass layer not only forms a space to accommodate the shooting component, provides physical protection for the shooting component, and reduces interference and damage to it by external factors, but also, due to its transparent characteristics, protects the shooting component without affecting the shooting field of view. The connecting rod tightly connects the driving component and the tempered glass layer, so that the power of the driving component can be transmitted to the tempered glass layer, thereby realizing the coordinated rotation of the protective component and other components.

[0020] As a further optimization of the patrol device, the transmission assembly includes a placement platform, a first bevel gear, a second bevel gear, a third bevel gear and a fourth bevel gear;

[0021] The placement platform is connected to the lower end of the machine body and is located outside the protection assembly, the first bevel gear is connected to the outside of the protection assembly and rotates synchronously with the protection assembly, the second bevel gear is coaxially connected with the third bevel gear and is located at both ends of the placement platform, and the fourth bevel gear is connected to the end of the support assembly;

[0022] The first bevel gear and the second bevel gear are meshed with each other, and the third bevel gear and the fourth bevel gear are meshed with each other.

[0023] In this solution, the first bevel gear transmits the rotation of the protection component and starts the power transmission chain; the second and third bevel gears that mesh with each other realize the coaxial transmission and direction change of power; the fourth bevel gear finally transmits the power to the support component. Through this transmission system, the rotation of the protection component can be accurately converted into the movement of the support component, so that the support component can be expanded or retracted along the axis of the fuselage. When the UAV approaches the detection equipment, it can play a protective role in time to avoid collision, ensure the safety of the UAV and the equipment in the station, and ensure that the entire patrol device can operate stably and efficiently in the complex converter station environment.

[0024] As a further optimization of the patrol device, the transmission assembly also includes a cleaning brush, which is connected to the outer side of the bottom of the placement table, and the cleaning surface of the cleaning brush is in contact with the outer wall surface of the protective assembly.

[0025] In this solution, when the patrol device is running, the protection component will rotate synchronously with the driving component, and the design of the cleaning brush fitting the outer wall of the protection component allows the cleaning brush to continuously wipe the outer wall of the protection component during its rotation, effectively preventing dust, stains and other impurities from accumulating on the outer wall of the protection component. In particular, for the critical tempered glass layer in the protection component, the cleaning brush can ensure that it always remains clear and transparent, ensuring that the shooting field of the shooting component is not affected, thereby improving the shooting quality and making the acquired inspection images or video data clearer and more accurate. In addition, the setting of the cleaning brush does not require additional operation or energy drive, and only requires the operation of the transmission component to realize the automatic cleaning function, which enhances the overall performance of the device and reduces maintenance costs without increasing the complexity of the device operation.

[0026] As a further optimization of the patrol device, the cleaning surface of the cleaning brush is made of sponge material.

[0027] As a further optimization of the patrol device, the support assembly includes a steering seat, a rotating shaft, a rotating arm, a spring rotating shaft, a support arm and a support foot;

[0028] The fourth bevel gear is arranged inside the steering seat, and the outer end of the fourth bevel gear is connected to the rotating shaft, the outer end of the rotating shaft is connected to the rotating arm, the end of the rotating arm is connected to the spring rotating shaft, the outer end of the spring rotating shaft is connected to the supporting arm, and the inside of the supporting arm is connected to the supporting foot.

[0029] In this solution, the fourth bevel gear is in the steering seat, receiving power from the transmission assembly, driving the rotating shaft to rotate, the rotating shaft drives the rotating arm to move, and then transmits it to the support arm through the spring shaft, and finally controls the movement of the support foot, so that the support assembly can achieve precise expansion and contraction actions under the drive of the transmission assembly; and during the drone inspection process, when approaching the detection equipment, the support foot is deployed in advance. If a collision occurs, the support foot reduces the collision damage between the drone and the equipment through the internal connection structure of the support arm and the buffering effect of the spring shaft, thereby protecting the safety of the drone and the equipment in the station; it can also play a buffering role during landing to ensure a smooth landing of the drone.

[0030] As a further optimization of the patrol device, a return spring is arranged inside the support arm, and the return spring provides a buffering elastic force for the support foot.

[0031] In this solution, the reset spring is set inside the support arm and provides buffering elasticity for the support foot, which greatly improves the device's ability to cope with collisions. When the drone approaches the equipment in the converter station for inspection, if the support foot accidentally contacts the equipment, the reset spring can be compressed instantly, effectively reducing the impact force caused by the collision and preventing the drone from being damaged by a violent collision.

[0032] As a further optimization of the patrol device, in order to further ensure the normal operation of the converter station, the diameter of the support assembly in the fully expanded state is greater than the diameter of the wing.

[0033] A method for inspecting a converter station UAV ultraviolet inspection device, applied to the above inspection device, is characterized by comprising the following steps:

[0034] S1: The propeller rotates to make the aircraft take off for inspection;

[0035] S2: The driving component operates, driving the shooting component to rotate in a circle, so that the camera can shoot at multiple angles. The pitch angle of the camera is adjusted through the electrically controlled shaft to expand the shooting range. The ultraviolet imager in the camera starts working. On the basis of conventional shooting, partial discharge detection is performed on the high-voltage equipment in the converter station, and the acquired image or video data is transmitted back to the monitoring terminal in real time.

[0036] S3: The protection component is driven to rotate by the driving component. During the rotation of the protection component, the meshing transmission between the bevel teeth drives the rotating shaft and the rotating arm to rotate inside the steering seat, so that the support foot is expanded or retracted along the axis of the body. If the device and the detection device are too close, the support foot will first contact the detection device. After the support foot contacts the detection device, the return spring is squeezed and retracted inside the support arm to buffer the collision force. At the same time, the support arm further buffers the collision force by driving the spring shaft to rotate;

[0037] S4: The cleaning brush at the bottom of the placement table is in contact with the tempered glass layer. When the tempered glass layer rotates, the cleaning brush rubs against the surface of the tempered glass layer.

[0038] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0039] 1. The present invention has a built-in ultraviolet imager in the shooting component, which can capture ultraviolet radiation accompanied by corona and partial discharge. The driving component drives the rotating seat to rotate the camera in a circle, and the electric control shaft adjusts the pitch angle of the camera to achieve multi-angle shooting, which can accurately identify the location and severity of equipment defects and comprehensively improve the inspection quality;

[0040] 2. The present invention is provided with an automatic protection structure formed by a protection component, a transmission component and a support component. When the motor drives the rotating seat to rotate, the tempered glass layer rotates synchronously, and the support feet are expanded or retracted through the bevel gear transmission. When the UAV approaches the detection equipment, the support feet first contact and use the return spring and the spring shaft to buffer the collision force. It can also buffer when landing, so as to protect the UAV and the equipment in the station in all directions.

[0041] 3. The automatic cleaning of the tempered glass layer and the automatic opening of the support feet of the present invention are automatically completed when the camera rotates to shoot, without additional operation. At the same time, the cleaning brush at the bottom of the placement table is made of sponge material, which rotates and cleans the tempered glass layer, keeps the camera's field of view clear, reduces the difficulty of operation, reduces the cost of manual maintenance, and improves the convenience and flexibility of equipment inspection in the converter station.

DETAILED DESCRIPTION

[0051] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0052] Example 1

[0053] This embodiment 1 provides a converter station drone ultraviolet inspection device, such as Figure 1-Figure 4 As shown, it includes a body 1, a shooting component 5 and a protective component 6. The outer wall of the body 1 is connected with wings 2, the outer end of the wing 2 is provided with a propeller 3, the outer end of the propeller 3 is provided with a protective cover 4, an ultraviolet imager is arranged inside the shooting component 5, and the shooting component 5 is connected to the lower end of the body 1 through a driving component, and a cavity for accommodating the shooting component 5 is provided in the middle of the protective component 6, the top of the cavity is connected to the output end of the driving component, and the outer side wall of the protective component 6 is rotatably connected to multiple groups of support components 8 through a transmission component 7. When the driving component drives the shooting component 5 and the protective component 6 to rotate synchronously, the multiple groups of support components 8 are expanded or retracted along the axis of the body 1 under the drive of the transmission component 7.

[0054] Among them, Figure 4 and Figure 6As shown, the shooting component 5 includes a rotating seat 502, a connecting seat 503, an electrically controlled rotating shaft 504 and a camera 505. One end of the rotating seat 502 is connected to the output end of the driving component. In this embodiment, the driving component is a rotating motor 501. The other end of the rotating seat 502 is connected to the camera 505 through the connecting seat 503. An electrically controlled rotating shaft 504 is arranged inside the connecting seat 505. The electrically controlled rotating shaft 504 drives the camera 505 to pitch and rotate.

[0055] In this embodiment, the body 1 can take off for inspection by rotating the propeller 3, and the protective cover 4 at the outer end of the wing 2 can protect the propeller 3 to prevent the propeller 3 from colliding with foreign objects. During the inspection, the motor 501 works to drive the rotating seat 502 to drive the camera 505 to rotate in a circle, which enables the camera 505 to achieve multi-angle shooting without adjusting the orientation of the fuselage, and the rotation of the electrically controlled shaft 504 can drive the camera 505 to adjust the pitch angle, which further improves the shooting angle of the camera 505. In addition, a UV imager is installed inside the camera 505, so High-voltage equipment may experience corona discharge and partial discharge, especially when the insulation deteriorates, the surface is contaminated, or the conductor is partially damaged. Partial discharge signals will appear in advance. Corona and partial discharge are often accompanied by ultraviolet radiation, which is invisible to the human eye. Ultraviolet imagers can capture high-frequency ultraviolet signals and visualize the discharge area through images or videos, thereby identifying the location and severity of equipment defects. This allows camera 505 to perform partial discharge detection on high-voltage equipment in the converter station through the ultraviolet imager in addition to routine inspection shooting. By coordinating the multi-angle shooting range of camera 505, the inspection quality of the equipment can be improved.

[0056] Among them, see Figures 1 to 6The protective component 6 includes a bearing seat 601, a tempered glass layer 602, and a connecting rod 603. One end of the bearing seat 601 is connected to the lower end of the body 1, and the other end of the bearing seat 602 is connected to the tempered glass layer 602 through a bearing. At the same time, a cavity for accommodating the shooting component 5 is formed in the middle of the tempered glass layer 602, and a connecting rod 603 is arranged on the inner side of the cavity. The two ends of the connecting rod 603 are respectively connected to the output end of the driving component and the tempered glass layer 602; and the transmission component 7 includes a placement platform 701, a first bevel gear 604, a second bevel gear 702, a third bevel gear 703 and a fourth bevel gear 802. The placement platform 701 is connected to the lower end of the body 1 and is located on the outer side of the tempered glass layer 602. The first bevel gear 604 is connected to the outer side of the tempered glass layer 602 and rotates synchronously with the tempered glass layer 602. The second bevel gear 702 is coaxially connected with the third bevel gear 703 and is located at both ends of the placement table 701. The fourth bevel gear 802 is connected to the end of the support assembly 8. In this embodiment, the first bevel gear 604 and the second bevel gear 702 are meshed with each other, and the third bevel gear 703 and the fourth bevel gear 802 are meshed with each other. The meshing bevel gears realize the coaxial transmission and steering change of power, and the fourth bevel gear 802 finally transmits the power to the support assembly. Through this transmission system, the rotation of the protection assembly 6 can be accurately converted into the movement of the support assembly 8, so that the support assembly 8 can be expanded or retracted along the axis of the body.

[0057] The above-mentioned support assembly 8 includes a steering seat 801, a rotating shaft 803, a rotating arm 804, a spring rotating shaft 805, a support arm 806 and a support foot 808. The interior of the steering seat 801 is connected to the above-mentioned fourth bevel gear 802, and the outer end of the fourth bevel gear 802 is connected to the rotating shaft 803, the outer end of the rotating shaft 803 is connected to the rotating arm 804, the end of the rotating arm 804 is connected to the spring rotating shaft 805, the outer end of the spring rotating shaft 805 is connected to the support arm 806, the interior of the support arm 806 is connected to the support foot 808 through a reset spring 807, and the reset spring 807 provides a buffering elastic force for the support foot 808.

[0058] At the same time, in order to ensure that the shooting field of view of the shooting component 5 is not affected, the transmission component 7 also includes a cleaning brush 704, which is connected to the outer side of the bottom of the placement table 701. The cleaning surface of the cleaning brush 704 is made of sponge material, such as polyurethane sponge, and fits with the outer wall of the tempered glass layer 602. When the patrol device is running, the tempered glass layer 602 will rotate synchronously with the driving component, and the design of the cleaning brush 704 fitting with the outer wall of the tempered glass layer 602 enables the cleaning brush 704 to continuously wipe the outer wall of the tempered glass layer 602 during its rotation, thereby effectively preventing dust, stains and other impurities from accumulating on the outer wall of the protective component.

[0059] In this embodiment, the tempered glass layer 602 surrounds the outer end of the camera 505, so that the tempered glass layer 602 can protect the camera 505 during the inspection process, which can greatly reduce the probability of damage to the camera 505. In addition, the rotating seat 502 is connected to the tempered glass layer 602 through the connecting rod 603. After the aircraft body 1 takes off, the rotating seat 502 is driven to rotate by the motor 501, which can make the tempered glass layer 602 rotate synchronously, and the tempered glass layer 602 rotates. During the process, the first bevel gear 604 at the outer end thereof can be driven to rotate, the first bevel gear 604 is meshed with the second bevel gear 702, the second bevel gear 702 is coaxially connected with the third bevel gear 703, and the third bevel gear 703 is meshed with the fourth bevel gear 802, so that during the rotation of the tempered glass layer 602, the meshing transmission between the bevel gears can drive the rotating shaft 803 and the rotating arm 804 to rotate inside the steering seat 801, and the rotation of the rotating arm 804 can make the supporting foot 808 rotate from the downward placement ( Figure 5 ) to face outwards ( Figure 1 ), and the support foot 808 in this state will be at a more outer position than the protective cover 4 at the outer end of the propeller 3. During the equipment inspection, if the equipment is too close to the detection equipment, the support foot 808 will first contact the detection equipment. After the support foot 808 contacts the detection equipment, it can buffer the collision force by squeezing the reset spring 807 to shrink inside the support arm 806. At the same time, the support arm 806 can further buffer the collision force by driving the spring shaft 805 to rotate, which improves the protection performance of the equipment inspection process. In addition, the design of the reset spring 807 and the spring shaft 805 can also provide buffering during the landing of the equipment, which makes the equipment The protective performance is further improved. In addition, the cleaning brush 704 at the bottom of the mounting platform 701 can fit with the tempered glass layer 602. When the tempered glass layer 602 rotates, the cleaning brush 704 will rub against the surface of the tempered glass layer 602, which allows the tempered glass layer 602 to always remain clean. The automatic cleaning of the tempered glass layer 602 and the operation of opening the supporting feet 808 for protection are both automatically achieved when the camera 505 rotates to shoot. Through this design, the equipment can have high protective performance and ensure shooting clarity while reducing the difficulty of operating the equipment, which can effectively improve the convenience and flexibility of equipment inspection in the converter station.

[0060] Example 2

[0061] Embodiment 2 provides a method for inspecting a converter station UAV ultraviolet inspection device based on Embodiment 1, comprising the following steps:

[0062] Take-off stage: Start the drone, and the propeller 3 starts to rotate, generating an upward thrust, so that the body 1 takes off smoothly. During the take-off process, the protective cover 4 at the outer end of the wing 2 can effectively prevent the propeller 3 from colliding with surrounding foreign objects, ensuring the flight safety of the drone and laying the foundation for subsequent inspection work.

[0063] Inspection operation stage: Motor 501 starts working, and its output power drives the rotating seat 502 to rotate in a circle. The rotation of the rotating seat 502 causes the camera 505 connected to it to rotate accordingly, thereby realizing multi-angle shooting. At the same time, the electric control shaft 504 is started, and the pitch angle of the camera 505 is adjusted by rotation to further expand the shooting range. The ultraviolet imager placed inside the camera 505 starts working. While performing conventional shooting, it uses ultraviolet imaging technology to perform partial discharge detection on the high-voltage equipment in the converter station. The image or video data captured by the shooting will be transmitted back to the monitoring terminal in real time, which is convenient for the staff to check and analyze the operating status of the equipment in a timely manner.

[0064] Protection stage: As the motor 501 drives the rotating seat 502 to rotate, the tempered glass layer 602 connected to the rotating seat 502 through the connecting rod 603 will also rotate synchronously, and the first bevel gear 604 fixed on the outer end of the tempered glass layer 602 will rotate accordingly, and the first bevel gear 604 and the second bevel gear 702 will mesh with each other, driving the second bevel gear 702 to rotate, and the second bevel gear 702 and the third bevel gear 703 are coaxially connected, so that the third bevel gear 703 also rotates, and the third bevel gear 703 and the fourth bevel gear 802 are meshed with each other, thereby driving the fourth bevel gear 802 to rotate. The fourth bevel gear 802 is connected to the rotating shaft 803. The rotation of the rotating shaft 803 drives the rotating arm 804 to rotate inside the steering seat 801, and finally rotates the support foot 808 from the downward placement state to the outward placement state; when the UAV approaches the detection equipment during the inspection process, the support foot 808 in the outward placement state will first contact the detection equipment. After the support foot 808 is hit, it will squeeze the return spring 807 inside the support arm 806, so that the support foot 808 shrinks inside the support arm 806 to buffer part of the collision force. At the same time, the support arm 806 will drive the spring shaft 805 to rotate, further dispersing and buffering the collision force, thereby protecting the UAV and the detection equipment from serious damage.

[0065] Cleaning stage: During the rotation of the tempered glass layer 602, the cleaning brush 704 at the bottom of the placement table 701 always keeps in contact with the outer surface of the tempered glass layer 602. Since the cleaning brush 704 is made of sponge material, it has a good cleaning effect. When the tempered glass layer 602 continues to rotate, the cleaning brush 704 will continuously rub on its surface, and promptly remove dust, stains and other impurities on the surface of the tempered glass layer 602, ensuring that the tempered glass layer 602 is always kept clean, thereby ensuring that the shooting field of view of the camera 505 is clear, so that the captured image or video data is not affected, and maintaining the accuracy of the inspection work.

[0066] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
