Description

Technical Field

[0001] The present invention belongs to the field of power transmission line operation, maintenance and repair, and relates to an unmanned aerial vehicle mobile vehicle-mounted inspection platform and an inspection vehicle for power transmission lines. Background Art

[0002] Compared with fixed-wing drones, multi-rotor drones have the advantages of small size, simple structure, strong controllability, and easy recovery. They are widely used in aerial photography and mapping, power inspection, search and rescue, agricultural and forestry plant protection, etc. Due to the strong flexibility of multi-rotor drones, their application rate is getting higher and higher, but at the same time, they also have the disadvantage of relatively short air stay time due to low efficiency of the propulsion system, which limits the autonomy and practicality of multi-rotor drones.

[0003] At the same time, with the development of transmission line drone inspection applications, the existing drone control mode mostly adopts the "one person, one controller, one machine" operation mode, and multiple machines are difficult to operate at the same time, which restricts the efficiency and quality of drone operations in time and space. At the same time, drones have their own limitations such as endurance time, operating radius, signal strength, positioning accuracy, etc. The personal technical level of the operator, emergency response capabilities, psychological quality of beyond visual range flight, practical experience in line inspection, and other personnel factors will affect the quality and efficiency of drones in transmission line operation and maintenance.

[0004] In order to effectively solve the problems of small operating radius of drones, difficult human control, and limited flight range, it is of great significance to apply auxiliary platforms that provide energy supply and recovery for drones, also known as drone hangars or nests. Without human intervention, drones can autonomously land on the hangar platform to complete charging and continue to perform tasks, achieving all-weather operations. The emergence of drone hangars can expand the operating area of ​​drones, thereby effectively realizing the automation and remoteness of drone operations. There are two types of electric drone hangars currently in use: fixed and mobile. Fixed drone hangars are deployed around substations or lines, which to a certain extent solves a series of problems such as short drone flight time and poor field protection measures. However, due to their limited radiation area and poor flexibility, they are not easy to deploy. At the same time, the fixed hangars on site need to be maintained on a daily basis, which makes it impossible for drones to complete inspection tasks with a relatively large operating range. Summary of the invention

[0005] The purpose of the present invention is to provide a mobile vehicle-mounted inspection platform and inspection vehicle for transmission lines using unmanned aerial vehicles, so as to solve the problems of the prior art that the radiation area is limited, the flexibility is poor and the deployment is difficult, and the unmanned aerial vehicles cannot complete the inspection tasks with a relatively large operating range.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A mobile vehicle-mounted inspection platform for UAVs used in power transmission lines includes an electrical box, a storage mechanism and a parking platform. The storage mechanism and the parking platform are connected. The storage mechanism is used to store multiple UAVs. The parking platform can move in the height direction of the storage mechanism and is used to launch or transport UAVs to the storage mechanism. The electrical box is used to supply power to the storage mechanism and the parking platform.

[0007] Furthermore, the storage mechanism includes a first conveyor belt, a second conveyor belt, a shell, a folding mechanism, a connecting bracket and a lifting mechanism. The first conveyor belt and the second conveyor belt are arranged in two layers in the shell, and a hinge shaft is provided on the connecting bracket. The parking platform is fixedly connected to the hinge shaft. The connecting bracket is connected to the lifting mechanism. The folding mechanism is installed on the connecting bracket and can drive the parking platform to rotate around the hinge shaft toward the storage mechanism.

[0008] Furthermore, the lifting mechanism includes a lifting motor and a lifting screw. The lifting motor is fixed on the shell, the lifting motor is connected to the lifting screw, the connecting bracket and the lifting screw are threadedly connected, and the rotation of the lifting screw drives the parking platform connected to the connecting bracket to move up and down.

[0009] Furthermore, the folding mechanism includes a folding motor, an output end of the folding motor is connected to the hinge shaft, and when the folding motor drives the hinge shaft to rotate, the parking platform is folded.

[0010] Furthermore, a third conveyor belt is arranged on the parking platform, and the parking platform can be flush with the first conveyor belt or the second conveyor belt when moving up and down; a grating position sensor is arranged at the bottom of the parking platform.

[0011] Furthermore, a left-right centering device is provided in the shell, and left-right centering devices are provided on the sides of the first conveyor belt, the second conveyor belt and the third conveyor belt, so as to keep the drone in the center position.

[0012] Furthermore, the left and right centering devices include a centering motor, a centering screw, a slider and a centering rod. The centering screw is arranged on the sides of the first conveyor belt, the second conveyor belt and the third conveyor belt. The centering motor is connected to the centering screw. Two sliders are arranged on the centering screw. Each slider is connected to the centering rod. The centering screw is provided with threads in opposite directions. When the centering screw rotates, it can drive the two sliders to move toward or away from each other.

[0013] Furthermore, the bottom of the first conveyor belt is supported by a support plate, and the second conveyor belt is arranged at the bottom of the shell. Fixed limit rods and folding limit rods are arranged in sequence under the bottom of the support plate and the inner top of the shell for positioning the drone on the conveyor belt.

[0014] Furthermore, the foldable limiting rod is connected to a steering gear fixed on the side wall of the housing.

[0015] A patrol vehicle comprises the above-mentioned mobile vehicle-mounted patrol platform for transmission lines using a drone, wherein the mobile vehicle-mounted patrol platform for transmission lines using a drone is installed in the trunk of the vehicle, and the parking platform is located outside the vehicle when unfolded.

[0016] Compared with the prior art, the present invention has the following technical effects: The present invention proposes a mobile vehicle-mounted inspection platform for transmission lines using an unmanned aerial vehicle, and an inspection vehicle comprising the platform, aiming to improve the application efficiency of the unmanned aerial vehicle and the utilization rate of the inspection vehicle through an integrated design, thereby expanding the operating scope and reducing the inspection cost.

[0017] The platform can store multiple drones, and through the cooperation of the parking platform and the storage mechanism, the drones can be quickly released and recovered. This avoids the tedious process of manually releasing and recovering drones in traditional inspections, and improves work efficiency.

[0018] Through the integration of motors, conveyor belts and folding mechanism automation components, the automated operation of drones in the storage, release, recovery and positioning processes is achieved. This reduces manual intervention and improves the accuracy and efficiency of operations.

[0019] The design of the left and right centering device enables the UAV to be quickly positioned and maintained in the center on the conveyor belt, providing a guarantee for the stable launch and recovery of the UAV.

[0020] The entire inspection platform is integrated into the trunk of the vehicle, and the parking platform can be deployed to the outside of the vehicle to launch and recover the drone when needed. This integrated design allows the inspection vehicle to carry multiple drones and inspection personnel at the same time, improving the utilization rate of the vehicle.

[0021] Since multiple drones can be operated simultaneously, inspectors can drive to more distant locations for inspection without having to worry about insufficient drones or inconvenience in launching and recovering them. This greatly expands the scope of inspection operations.

[0022] The automated and integrated design reduces the manpower requirements and labor costs during the inspection process. The inspection efficiency is significantly improved by quickly launching, recovering and positioning drones, as well as operating multiple drones for inspection at the same time. This reduces the cost of inspection per unit time.

[0023] The present invention improves the stability and safety of the UAV on the conveyor belt through the design of a fixed limit rod and a foldable limit rod and the use of a grating position sensor, thereby avoiding damage to the UAV during the release, recovery or transportation process.

[0024] In summary, this technical solution improves the application efficiency of drones and the utilization rate of inspection vehicles through integrated, automated and intelligent design, reduces inspection costs, and enhances the safety and adaptability of inspections. It provides an efficient and low-cost solution for the inspection of power transmission lines. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The parking platform 3 can move in the height direction of the storage mechanism 2, which is convenient for the rapid launch and recovery of the UAV, further improving the continuity and efficiency of the inspection.

[0036] The drone can reach areas that are difficult for personnel to reach or dangerous for inspection, reducing the risk of personnel being directly exposed to high altitudes or complex terrain.

[0040] The highly integrated design of the entire system makes operation easier, maintenance and upgrades easier, providing a good foundation for future intelligent inspections.

[0041] In summary, the technical solution of this type of UAV mobile vehicle-mounted inspection platform for transmission lines has significant technical effects in improving inspection efficiency, enhancing safety, improving inspection quality, improving flexibility and adaptability, reducing operation and maintenance costs, and promoting integration and intelligence.

[0042] Embodiment 2, the present invention provides a UAV mobile vehicle-mounted inspection platform for power transmission lines, specifically comprising: The electric box 1, the storage mechanism 2 and the parking platform 3. The storage mechanism 2 is closely connected with the parking platform 3 and is specially used to store multiple drones. The parking platform 3 can move freely in the height direction of the storage mechanism 2, which is convenient for launching drones and returning drones to the storage mechanism. The electric box 1 serves as the energy center of the entire system, providing stable power support for the storage mechanism 2 and the parking platform 3.

[0043] The storage mechanism of the inspection platform includes a first conveyor belt 4, a second conveyor belt 5, a shell 6, a folding mechanism, a connecting bracket and a lifting mechanism. The first conveyor belt 4 and the second conveyor belt 5 are arranged in layers in the shell 6 to form a double-layer conveying system. A hinge shaft is installed on the connecting bracket, and the parking platform 3 is fixed on this hinge shaft. The connecting bracket is also connected to the lifting mechanism, so that the parking platform 3 can be raised and lowered. In addition, the folding mechanism is installed on the connecting bracket, which can drive the parking platform 3 to rotate around the hinge shaft to achieve precise docking with the storage mechanism. The specific implementation method of the lifting mechanism is to drive the lifting screw 8 through the lifting motor 7, thereby driving the parking platform 3 to move up and down.

[0044] The folding mechanism is driven by a folding motor 9 and is hinged through a connecting shaft to achieve rapid folding of the parking platform. The parking platform 3 is equipped with a third conveyor belt 10. When the parking platform moves up and down, it can be perfectly aligned with the first conveyor belt 4 or the second conveyor belt 5 to ensure the smooth transfer of the UAV. At the same time, a grating position sensor 18 is installed at the bottom of the parking platform to accurately monitor the platform position. In order to maintain the stability of the UAV during the transportation process, a left and right centering device is also provided in the shell 6. The device consists of a centering motor 11, a centering screw 12, a slider 13 and a centering rod 14, which can automatically adjust the position of the UAV to ensure that it is always in the center. In addition, a fixed limit rod 15 and a folding limit rod 16 are provided under the conveyor belt, which are connected to the servo 17 on the side wall of the shell to provide all-round positioning support for the UAV.

[0045] The platform can store multiple drones, and through the cooperation of the parking platform and the storage mechanism, the drones can be quickly released and recovered. This avoids the tedious process of manually releasing and recovering drones in traditional inspections, and improves work efficiency.

[0046] Through the integration of motors, conveyor belts and folding mechanism automation components, the automated operation of drones in the storage, release, recovery and positioning processes is achieved. This reduces manual intervention and improves the accuracy and efficiency of operations.

[0047] Figure 1 In the figure, the structure is divided into three parts from left to right: Electric box 1: Built-in control system and board to realize the control of hangar structure; Storage mechanism 2: capable of storing up to 4 drones; Parking platform 3: The platform is equipped with a centering push rod, and can be rotated and folded at the conveyor belt B by a motor to realize the retractable and unretractable operation of the parking platform, which is convenient for vehicle-mounted application. The specific description is attached.

[0048] Specifically: 1) Parking platform with folding mechanism: When the drone does not need to work, the parking platform 3 is folded up around the rotation center by driving the folding motor 9. The folding motor 9 is connected to the hinge shaft, and the parking platform 3 is folded when the hinge shaft rotates, and the drone is put down when it needs to land; The lifting function is driven by the lifting mechanism, which includes a lifting motor 7 and a lifting screw 8. The lifting motor 7 is fixed on the housing 6, and the lifting motor 7 is connected to the lifting screw 8. The lifting screw 8 rotates to drive the parking platform 3 to move up and down. On the parking platform, a grating position sensor 18 is configured to detect the presence of a drone. The grating position sensor 18 is installed at the bottom of the parking platform to detect whether the drone is located at the center of the platform.

[0049] The storage mechanism 2 is divided into two layers, and each layer can store two drones. After the aircraft stops on the parking platform 3, the left and right centering devices on the storage platform push the drone to the center of the platform.

[0050] The left and right centering devices include a centering motor 11, a centering screw 12, a slider 13 and a centering rod 14. The centering screw 12 is arranged on the sides of the first conveyor belt 4, the second conveyor belt 5 and the third conveyor belt 10. The centering motor 11 is connected to the centering screw 12. Two sliders 13 are arranged on the centering screw 12. Each slider 13 is connected to the centering rod 14. The centering screw 12 is provided with threads in opposite directions. When the centering screw 12 rotates, it can drive the two sliders 13 to move toward or away from each other.

[0051] The centering rod 14 is driven by the centering screw 12 and the centering motor 11. The rotation of the centering motor 11 drives the centering screw 12 to rotate. The slider 13 on the centering screw 12 is fixedly connected to the centering rod. The rotation of the centering screw 12 drives the centering rod 14 to move, pushing the UAV gradually closer to the middle of the conveyor belt, achieving fixation in the middle of the platform, and then conveying the aircraft to the first conveyor belt 4 or the second conveyor belt 5 through the third conveyor belt 10; A guide rod is arranged above the first conveyor belt 4 or the second conveyor belt 5. The guide rod itself remains fixed and does not move. At the same time, the guide rod is fixedly connected to the shell 6, and the guide rod is fixedly connected to the fixed limit rod, ensuring that the aircraft always maintains the center position when moving on the conveyor belt and automatically stays at the preset position.

[0052] The outer shell includes a fixed limit rod 15 to limit the stop position of the aircraft; the outer shell also includes a servo 17 with a foldable limit rod 16. The servo 17 body is fixedly connected to the shell 6, and the rotating shaft is fixedly connected to the foldable limit rod 16 to control the up and down movement of the foldable limit rod to achieve the limit of the aircraft. Figure 2 , Figure 4 and Figure 5 .

[0053] The action flow of the present invention: The parking platform is unfolded / folded, the drone of the first conveyor belt 4 is put in / out, and the drone of the second conveyor belt 5 is put in / out. Finally, the parking platform will move to the highest position equal to the first conveyor belt 4 or the second conveyor belt 5 to release the drone.

[0054] like Figure 3 As shown, the parking platform is unfolded / folded: the unfolding is controlled by the folding motor 9, which rotates along the hinge axis, and the movement of the parking platform is achieved by the folding motor 9 rotating in the opposite direction during folding.

[0055] The first conveyor belt 4 moves the drone in and out of the warehouse: the first conveyor belt 4 rotates along the direction of the arrow, driving the aircraft 1 on it to move in the direction of moving out of the warehouse. At the same time, the foldable limit rod fixed on the external shell is raised by the steering gear 17 to ensure that the aircraft is automatically pushed onto the external lifting platform; the opposite direction is used for entering the warehouse.

[0056] Second conveyor belt 5 UAV out of warehouse / in of warehouse: out of warehouse along Figure 3 In the direction of the middle arrow, the second conveyor belt 5 rotates, driving the aircraft on it to move in the direction of leaving the warehouse. At the same time, the foldable limit rod fixed on the external shell is raised by the steering gear to ensure that the aircraft is automatically pushed onto the external lifting platform; the opposite direction is used for entering the warehouse.

[0057] In Example 2, the platform can store multiple drones, and through the close cooperation between the parking platform and the storage mechanism, the drones can be quickly released and recovered. This function avoids the tedious process of manually releasing and recovering drones in traditional inspections, and significantly improves work efficiency.

[0058] By integrating automated components such as motors, conveyor belts and folding mechanisms, the platform realizes fully automated operation of drones during storage, release, recovery and positioning. This not only reduces manual intervention, but also greatly improves the accuracy and efficiency of operations.

[0059] The third conveyor belt on the parking platform can be perfectly aligned with the first and second conveyor belts to ensure the smooth transfer of the drone. At the same time, the application of grating position sensors and left and right centering devices allows the drone to always maintain the center position during the conveying process, enhancing the stability of the system.

[0060] The fixed limit rod and foldable limit rod set under the storage mechanism are connected to the steering gear on the side wall of the shell, which together provide all-round positioning support for the drone. This design effectively prevents the drone from deflecting and falling during transportation and improves the reliability of the system.

[0061] The storage mechanism adopts a double-layer conveyor belt design, which enables the platform to store more drones in a limited space and improves space utilization.

[0062] The parking platform has a folding function. When the drone is not in use, the parking platform can be folded up through the folding motor for easy vehicle application and storage. This design not only saves space, but also improves the portability of the platform.

[0063] The control system and boards are built into the electrical box, which realizes the intelligent control of the entire hangar structure. Users can remotely monitor and operate the storage, launch, and recovery of drones through the control system, which improves the intelligence level of the platform.

[0064] Through precise control of components such as the centering motor and the centering screw, the platform can achieve precise adjustment of the position of the drone. At the same time, the application of feedback devices such as grating position sensors enables the platform to monitor the status of the drone in real time, improving the accuracy and reliability of control.

[0065] In summary, the UAV mobile vehicle-mounted inspection platform for power transmission lines described in Example 2 has shown significant technical effects in improving operating efficiency, enhancing system stability, optimizing spatial layout, and improving the level of intelligence. This platform not only meets the actual needs of power transmission line inspection, but also provides strong technical support for the widespread application of UAVs in the field of power inspection in the future.

[0066] Embodiment 3, the present invention provides an inspection vehicle, comprising the above-mentioned UAV mobile vehicle-mounted inspection platform for power transmission lines, wherein the UAV mobile vehicle-mounted inspection platform for power transmission lines is installed in the trunk of the vehicle, and the parking platform 3 is located outside the vehicle when unfolded.

[0067] The transmission line mobile vehicle inspection platform for unmanned aerial vehicles is deployed on the power inspection vehicle, and the control system platform of the control box is led out to the cab. After opening the trunk door, the parking platform 3 can be turned 90 degrees around the axis outside the conveyor belt of the folding motor 9 through the control button in the cab, forming the preparation before the unmanned aerial vehicle takes off. The unmanned aerial vehicle is pushed out through the first conveyor belt 4, and the unmanned aerial vehicle is fixed in the center on the platform through the limit rod and the left and right centering device of the parking platform 3, and the position of the unmanned aerial vehicle is accurately located through the position detection sensor. After the action is completed, the unmanned aerial vehicle controller is used to control the unmanned aerial vehicle to take off.

[0068] During recovery, the drone is pushed back onto the first conveyor belt 4 through the limiting mechanism of the parking platform, and the first conveyor belt 4 brings the drone back to the specified position, and the positioning of the drone on the conveyor belt is achieved by lifting the limiting rod, thereby finally realizing the recovery operation of the drone. Example 3 integrates the transmission line UAV mobile vehicle inspection platform into the trunk of the inspection vehicle, achieving a high degree of integration between the UAV and the inspection vehicle. This design not only saves space, but also improves the portability and use efficiency of the equipment.

[0069] The parking platform can be turned 90 degrees around the folding motor shaft, making the preparation work before the drone takes off more convenient. This operation can be achieved through the control button in the cab, which greatly improves the convenience and efficiency of operation.

[0070] The control system platform of the control box is led out to the cab, so that the driver can remotely monitor and operate the drone in the cab. This design improves the intelligence level of the inspection vehicle and makes the operation more intuitive and convenient.

[0071] The entire process, from launching the drone, centering and fixing it, detecting its position, taking it off, to pushing it back, bringing it back, and positioning it during recovery, is automated, which not only reduces manual intervention, but also improves the accuracy and efficiency of the operation.

[0072] The stopper rod and left and right centering devices of the parking platform can ensure that the drone is fixed in the center of the platform, preventing the drone from deviating or falling during takeoff or recovery. At the same time, the application of position detection sensors also further improves the positioning accuracy of the drone, thereby ensuring the safety of operation.

[0073] The positioning of the drone on the conveyor belt is achieved by lifting the limit rod, ensuring the stability of the drone during the recovery process. This design effectively prevents damage or accidents caused by unstable position of the drone during the recovery process.

[0074] After the inspection vehicle is equipped with a UAV mobile vehicle inspection platform, it can realize fast and efficient inspection of the transmission line. The UAV can cover a wider area and discover more potential problems, thereby improving the efficiency and accuracy of the inspection.

[0075] Since the inspection vehicles are mobile, the inspection routes and times can be flexibly adjusted according to actual needs. At the same time, drones can also be replaced or adjusted according to different inspection tasks, making the entire inspection system more flexible and adaptable.

[0076] In summary, the inspection vehicle described in Example 3 and the mobile vehicle-mounted inspection platform for transmission line UAVs carried by it have shown remarkable technical effects in terms of integration and convenience, intelligence and automation, safety and stability, and high efficiency and flexibility. This type of inspection vehicle not only improves the efficiency and accuracy of power inspections, but also provides strong technical support and demonstration cases for the widespread application of UAVs in the field of power inspections in the future.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
