Description

Technical Field

[0001] The present invention relates to the field of power inspection UAV endurance technology, and in particular to an adjustable UAV charging device used on a power engineering vehicle. Background Art

[0002] In order to ensure the safe and stable operation of outdoor power transmission and distribution lines, power workers need to conduct regular normal inspections and drone inspections of the lines to ensure that hidden dangers and defects of the lines are discovered and eliminated in a timely manner. This includes checking whether the foundation of the pole tower is damaged by settlement, whether the screws in the live parts are tightened and whether the pins are missing, whether the parasol skirts of the pole tower insulators are broken, whether the bird-proofing facilities on the top of the pole tower are complete and loose, and checking whether there are any factors around the line that may affect the safe and stable operation of the line.

[0003] With the rapid development of science and technology, drones are being used more and more widely in power operations. Drone operations have certain advantages, mainly including efficiency, safety, flexibility and precision.

[0004] ‌High efficiency‌ means that drones can complete large-scale operations in a short period of time through autonomous flight, greatly improving operational efficiency;

[0005] Safety means that drones can operate in high-risk working environments or in adverse weather conditions, reducing the operating risks of operators;

[0006] Flexibility: UAVs can fly freely without being restricted by terrain or topography, and can reach places that are difficult for humans to reach. For example, in complex environments such as mountains, forests, and oceans, UAVs can complete tasks quickly and accurately. At the same time, UAVs can flexibly adjust their flight altitude and speed according to mission requirements.

[0007] ‌Precision is achieved through advanced navigation systems and sensors, which allow drones to achieve precise positioning and stable flight.

[0008] In the current power repair and maintenance, drones are usually used for operations, which has improved work efficiency and quality to a certain extent. However, in the process of drone inspections and temperature measurement of transmission lines, the operation time of drones is affected by battery problems, which restricts the efficiency of drone operations. The existing method to increase the endurance of drones is to charge the drone batteries in advance. A large number of batteries need to be carried to the field for inspection operations, and the batteries cannot be charged in time after they are consumed.

[0009] At present, the way operators solve this problem is to extend the operation time of the drone by carrying a large number of drone batteries. However, after use, the batteries cannot be charged in time because they are outdoors. The drone batteries need to be brought indoors and charged in a special charging cabinet. This method seriously restricts the efficiency of the drone during patrols, and the batteries are not used in time, which seriously affects the operation efficiency.

[0050] like Figures 1 to 7 As shown, it shows a specific embodiment of the present invention:

[0051] Embodiment 1

[0052] The adjustable UAV charging device used in an electric engineering vehicle comprises a solar panel 1, a solar panel fixing bracket 2, a voltage stabilizing inverter, a UAV charging module, a system operation monitoring module, a cable connecting line, a shock absorbing rubber sleeve, and a heat dissipation module.

[0053] The solar panel fixing bracket 2 is installed on the roof of the electric engineering vehicle 3, the solar panel 1 is installed on the solar panel fixing bracket 2, the voltage stabilizing inverter and the drone charging module are installed in the compartment of the electric engineering vehicle 3, the system operation monitoring module is installed in the cab, the cable connecting line connects the solar panel 1 and the voltage stabilizing inverter, the output end of the voltage stabilizing inverter is connected to the drone charging module, the shock-absorbing rubber sleeve is installed at the position where the solar panel fixing bracket 2 is connected to the electric engineering vehicle 3 to ensure the stability of the solar panel 1 during the driving process of the electric engineering vehicle 3, and the heat dissipation module is installed on one side of the drone charging module. The drone charging module will generate heat when charging, and the heat dissipation module dissipates the heat generated in the process to ensure that the drone charging module operates within an adapted temperature range.

[0054] This embodiment is proposed based on the climate characteristics of the southern Xinjiang region and the essence of the field power transmission and distribution line inspection work. When conducting field power transmission and distribution line inspection work, operators need to drive electric engineering vehicles to the corresponding locations to carry out operations. The use of drones can improve work efficiency to a certain extent. At the same time, drone operations can discover hidden dangers and defects at high places on power transmission and distribution line towers, avoid the risk of heights for patrol operators, and ensure the personal safety of patrol operators. Therefore, drones are chosen to perform operations, but there is a problem of endurance difficulties during drone operations. In combination with the above characteristics, this embodiment 1 is proposed.

[0055] In this embodiment, the charging device makes full use of the climate characteristics of strong sunlight in southern Xinjiang. When working in the field, the solar panel 1 is installed on the roof of the electric engineering vehicle 3 through the solar panel fixing bracket 2, and the solar energy is used to charge the exhausted drone battery, so that the drone battery can be continuously charged in the field, improving the working efficiency of the drone pilot. At the same time, the charging device can realize the function of convenient charging, and the charging process of the drone battery does not affect the driving of the vehicle. The entire drone charging device can be detachably installed, and the installation process will not cause damage to the vehicle and other related parts.

[0056] In this embodiment, if Figure 1 As shown, the solar panel 1 is fixed on the roof through a solar panel fixing bracket 2, the solar panel 1 absorbs solar energy, the cable connecting line connects the solar panel 1 and the voltage stabilizing inverter, and the solar energy absorbed by the solar panel 1 is transmitted to the voltage stabilizing inverter through the cable connecting line, and then the voltage stabilizing inverter provides electric energy to the UAV charging module. In this way, the solar panel 1 on the roof of the electric engineering vehicle 3 converts solar energy into electric energy for charging the UAV during power inspection work outdoors, thereby solving the endurance problem of the UAV in the field working environment, allowing the UAV to operate continuously for a long time, thereby improving work efficiency and ensuring the safe and stable operation of the power grid.

[0057] In this embodiment, the voltage stabilizing inverter and the drone charging module are installed in the compartment of the electric engineering vehicle 3. The voltage stabilizing inverter and the drone charging module are installed in the compartment of the electric engineering vehicle 3, which is convenient for charging the drone when the battery is exhausted. The battery of the drone is directly inserted into the drone charging module, which is simple and convenient to operate; the system operation monitoring module is installed in the cab, and the system operation monitoring module is connected to the drone charging module in the compartment. The system operation monitoring module displays the working status of the drone charging module, which is specifically divided into three working states: charging, completed, and not charged. Through this module, during the process of power repair and maintenance of the electric engineering vehicle 3, especially when the electric engineering vehicle 3 is in motion, the status of the drone charging module can be directly observed in the cab, so as to carry out the next work plan and improve work efficiency.

[0058] Specifically, the drone charging module adopts a customized module with four charging card slots, which can charge four batteries at a time.

[0059] In this embodiment, in actual use on site, the main drones used are the M series and DJI Mavic series. The battery capacity of the M series is 5935mAh, and the battery capacity of the DJI Mavic series drone is 5000 mAh. Due to the large battery capacity of the M series, two batteries are required when the aircraft is flying, so the drone charging module adopts a customized module. At the same time, due to the smaller battery of the DJI Mavic series, the official standard battery manager charges 3 batteries at a time. In order to achieve high efficiency in the charging process, the customized module is provided with four charging card slots, which can not only meet the use requirements of the M series drone charging, that is, two sets of batteries can be charged at a time, but also meet the charging and use requirements of the DJI Mavic series drone, that is, 3 batteries can be charged at a time, which is suitable for the on-site environment of emergency repair and maintenance.

[0060] Embodiment 2

[0061] On the basis of the above-mentioned embodiment 1, on most days with clear weather, the solar panel 1 can meet the endurance problem of the drone operation. When encountering rainy weather, it is impossible to obtain electricity to meet the endurance use requirements of the drone. In order to ensure that the operators are not restricted by the weather environment when using the drone for operations, embodiment 2 is specially proposed.

[0062] Specifically, it also includes a portable mobile power source, which is connected to the voltage stabilizing inverter through a connecting line.

[0063] In this embodiment, a portable mobile power supply is provided, and the portable mobile power supply is connected to a voltage-stabilizing inverter through a connecting line. The portable mobile power supply stores excess electric energy generated by the solar panels in sunny weather. When the electric energy generated by the solar panels cannot meet the use requirements of the drone due to insufficient sunlight, the battery of the drone is charged by the portable mobile power supply to provide stable endurance for the operation of the drone, so that the operation process is not restricted by the weather environment, thereby ensuring the orderly implementation of the power line inspection work.

[0064] Specifically, the portable mobile power source is a mobile power source with a mains power interface.

[0065] In this embodiment, a portable mobile power supply with a mains power interface is used, which is convenient for charging the drone battery by directly connecting the drone charging module to the portable mobile power supply during use, which is more efficient, simple to operate and easy to use.

[0066] Embodiment 3

[0067] On the basis of the above-mentioned Embodiments 1 and 2, in the actual use of drone operations, due to the wide distribution of the operation area, the staff cannot always move in the south direction when driving the electric engineering vehicle. In this way, the power conversion efficiency of the solar panel will be reduced, and it will not be able to adapt to the continuous operation time of a whole day and maximize the operation efficiency. Based on this, we specially propose Embodiment 3 to solve the above problems.

[0068] Specifically, the solar panel fixing bracket 2 is an adjustable fixing bracket, including a bracket assembly 21, a fixing plate 22, a first motor 23, a turntable 24, a first bracket 25, a second bracket 26, a rotating shaft 27, a second motor 28, and a solar panel frame 29. The bracket assembly 21 is fixedly installed on the roof of the electric engineering vehicle 3, and the bracket assembly 21 provides a stable support. The fixing plate 22 is installed on the upper surface of the bracket assembly 21, and a mounting hole is opened in the middle of the fixing plate 22. The first motor 23 is installed on the lower surface of the fixing plate 22, and the turntable 24 is located on the upper surface of the fixing plate 22. The output shaft of a motor 23 is connected to the middle position of the turntable 24, the first bracket 25 and the second bracket 26 are both fixedly mounted on the upper surface of the turntable 24, the first bracket 25 is located at the left position, and the second bracket 26 is located at the right position, the rotating shaft 27 is located at the top position of the first bracket 25 and the second bracket 26, connecting the first bracket 25 and the second bracket 26, the second motor 28 is installed at the outer position of the first bracket 25, and the output shaft of the second motor 28 is connected to the rotating shaft 27, and a connecting ring 291 is provided in the middle position of the lower surface of the solar panel frame 29, and the connecting ring 291 is fixedly connected to the rotating shaft 27.

[0069] In this embodiment, if Figure 2 As shown, the solar panel fixing bracket 2 is an adjustable fixing bracket. The use of the adjustable solar panel fixing bracket 2 allows the electric engineering vehicle 3 to always face south in the horizontal plane by adjusting the angle of the solar panel fixing bracket 2 according to different driving directions during driving. At the same time, due to the changes in different seasons of the year, the incident angle of sunlight on the solar panel 1 is different. Therefore, the angle of the solar panel 1 is designed to be adjustable in the vertical plane, and is adjusted according to the optimal angle of different seasons, ultimately realizing the maximization of solar energy conversion efficiency and providing stable endurance for UAV operations.

[0070] In this embodiment, the adjustable fixed bracket specifically includes a bracket assembly 21, a fixing plate 22, a first motor 23, a turntable 24, a first bracket 25, a second bracket 26, a rotating shaft 27, a second motor 28, and a solar panel frame 29. The adjustable fixed bracket realizes the rotation of the turntable 24 by the rotation of the first motor 28, thereby realizing the rotation of the solar panel 1 connected to the rotating shaft 27 in the horizontal plane. In this way, regardless of whether the driving direction of the electric engineering vehicle faces the sun, the solar panel can always face the south position by adjusting the rotation angle of the turntable. By adjusting the rotation of the rotating shaft 27 by the second motor 28, the angle of the solar panel frame 29 fixedly installed on the rotating shaft 27 in the vertical plane is adjusted. The angle of the solar panel in the vertical plane is adjusted in each season of the year, so that the power generation efficiency of the solar panel 1 is the highest, providing a stable energy source for charging the drone.

[0071] Specifically, the first bracket 25 and the second bracket 26 have the same structure, which is a trapezoidal structure. A protrusion 251 is provided on the top thereof. The protrusion 251 is provided with a second mounting hole 252. The rotating shaft 27 is connected to the second mounting hole 252 on the protrusion 25 of the first bracket 25 and the second bracket 26.

[0072] In this embodiment, Figure 3 As shown, the rotating shaft 27 is located at the top of the first bracket 25 and the second bracket 26, connecting the first bracket 25 and the second bracket 26. The rotating shaft 27 provides power for the rotation of the solar panel 1 in the vertical plane, so that the solar panel frame 29 connected to the rotating shaft 27 rotates, thereby causing the solar panel 1 to rotate in the vertical plane.

[0073] In this embodiment, Figure 4 As shown, the first bracket 25 and the second bracket 26 with a trapezoidal structure design can ensure good stability, so that the solar panel 1 installed thereon has good stability during the driving of the electric engineering vehicle 3, ensuring safe use. The protrusion 251 on the first bracket 25 and the second bracket 26 is located at the top position, and the rotating shaft 27 is installed through the second mounting hole 252 opened on the protrusion 251, and cooperates with the second motor 28 installed on the outer side of the first bracket 25. When the second motor 28 rotates, the rotating shaft 27 is rotated.

[0074] In this embodiment, Figure 6 As shown, a connecting ring 291 is provided in the middle position of the lower surface of the solar panel frame 29, and the connecting ring 291 is fixedly connected to the rotating shaft 27. The solar panel fixing frame 29 is fixed to the rotating shaft 27 by the setting of the connecting ring 291 to realize the rotation of the solar panel frame 29. At the same time, the solar panel frame 29 adopts a reinforced aluminum alloy structure, which is easy to install and has sufficient strength to ensure safety during use.

[0075] Specifically, the first motor 23 and the second motor 28 are stepper motors, and switches of the first motor 23 and the second motor 28 are arranged in the cab.

[0076] In this embodiment, the switches of the first motor 23 and the second motor 28 are arranged in the cab, so that the operator can adjust the angles of the solar panel 1 in the horizontal plane and the vertical plane respectively by turning on the switches of the first motor 23 and the second motor 28 according to the driving route during the driving of the electric engineering vehicle 3. The operation is convenient and the optimal energy conversion efficiency is ensured.

[0077] In the present embodiment, the first motor 23 and the second motor 28 are both stepper motors. The stepper motor is an electric motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates an angle or moves forward one step. The angular displacement or linear displacement output is proportional to the number of input pulses, and the rotation speed is proportional to the pulse frequency. Selecting a stepper motor as the angle control variable can conveniently and accurately achieve angle control.

[0078] Specifically, the bracket assembly 21 has four groups, which are square structures and are made of reinforced aluminum alloy. They are located at the four corners below the fixing plate 22, respectively, and include a mounting plate 211, a column 212, and a connecting rod 213. The mounting plate 211 is provided with first mounting holes 2111 at the four corners. Bolts are passed through the first mounting holes 2111 to fix the mounting plate 211 to the roof. The column 212 is fixed to the upper surface of the mounting plate 211, and the connecting rod 213 connects the columns 212.

[0079] In this embodiment, if Figure 5 As described above, four sets of bracket assemblies 21 are fixed under the fixing plate 22, so that the fixing plate 22 can be stably and reliably installed on the roof of the electric engineering vehicle 3. Figure 7 As shown, the mounting plate 211 is fixed to the roof of the electric engineering vehicle by bolts through the first mounting holes 2111 thereon, which is easy to operate and can be reliably installed.

[0080] In this embodiment, the bracket assembly 21 is made of reinforced aluminum alloy. The reinforced aluminum alloy structure has the following characteristics:

[0081] The reinforced aluminum alloy structure has the characteristics of high strength and rigidity, and can withstand large external forces and impacts to ensure the safety and stability of the structure. A dense oxide layer can be formed on the surface of the aluminum alloy to effectively prevent corrosion and chemical reactions and extend the service life. The aluminum alloy has a low density and light weight, which can greatly reduce the overall weight. The aluminum alloy material has excellent anti-corrosion properties and a service life of more than 10 years.

[0082] The use of aluminum alloy material to make the bracket assembly 21 can make its structural strength meet the use requirements, while being reliable and durable, having a long service life and being more economical.

[0083] Specifically, the bracket assembly 21 further includes an oblique brace 214 , one end of which is fixedly connected to the column 212 , and the other end of which is fixedly connected to the mounting plate 211 .

[0084] In this embodiment, Figure 5 , Figure 7 As shown, the design of the diagonal brace 214 provides the column 212 with an oblique supporting force, which has better stability. This is because the diagonal brace 214, the column 212, and the mounting plate 211 form a triangular structure. Based on the stability of the triangle, the bracket assembly 21 can ensure better stability.

[0085] Embodiment 4

[0086] Specifically, the solar panel 1 is a 1200mm*2200mm, 300W solar panel.

[0087] In this embodiment, a 1200mm*2200mm, 300W solar panel can meet the usage requirements.

[0088] In actual use, taking the southern Xinjiang region as an example, the average outdoor power generation in summer is about 16 hours and in winter is about 8 hours. According to the outdoor power generation for 12 hours in summer, the power generation of a 300-watt solar panel is about 3.2 kWh per day. Calculated at 0.3 kWh per hour, 300 watts is equivalent to 0.3 kilowatts. According to the relationship between power and time:

[0089]

[0090] Assuming the power P is 0.3 kW and the time t is 1 hour, the energy consumed is 0.3 kWh. Therefore, the power generation of a 300-watt solar panel in one day (12 hours) is 0.3 kWh multiplied by 12, that is, 3.6 kWh, or 3.6 kWh. Considering factors such as solar panel pollution and voltage drop during the conversion rate transmission, the daily outdoor power generation is calculated to be 2.7 kWh based on a comprehensive conversion rate of 75%.

[0091] The actual continuous flight time of the DJI Mavic 3T series drones is 45 minutes. With the three endurance batteries and the rest time during work, the drone's endurance can basically reach 3 hours. In the case of 8 hours of working time a day, using a 4-card slot drone charging module, the drone motor needs to be charged 3 times, each charging time is 3 hours, and the drone and remote control are charged at the same time, which just realizes the drone's cycle operation and solves the endurance problem.

[0092] To sum up, through the above four embodiments, the UAV charging device can make full use of the climate characteristics of strong sunlight in southern Xinjiang. When working in the field, the solar panel is installed on the roof of the electric engineering vehicle through the solar panel fixing bracket, and the exhausted UAV battery is charged by using solar energy, so as to achieve the endurance of the UAV battery in the field and improve the operation efficiency of the UAV pilot. At the same time, the angle adjustment of the solar panel in the horizontal plane and the vertical plane is realized by using an adjustable fixing bracket, so that the power generation efficiency of the solar panel is the highest, providing a stable energy source for charging the UAV, and using a portable mobile power supply to store the excess electricity generated by the solar panel in sunny weather. In rainy weather, it is charged by a portable mobile power supply to provide stable endurance for the operation of the UAV, and ensure the orderly development of power maintenance work or power inspection work.
