Description

Technical Field

[0001] This invention relates to the technical field of attitude compensation power output mechanisms, and more particularly to a flight attitude compensation power output mechanism for a jet cleaning UAV. Background Technology

[0002] During flight, an aircraft's attitude can typically be divided into three attitude motion channels: roll, yaw, and pitch. For axisymmetric aircraft, the coupling between these three channels is weak. Therefore, the influence of coupling on the flight attitude of an axisymmetric aircraft can be treated as a small random perturbation, allowing for the construction of a small perturbation aerodynamic model. Currently, based on this small perturbation aerodynamic model, three independent attitude controllers are typically set up within the axisymmetric aircraft to control the angular velocities of the pitch, yaw, and roll channels, respectively.

[0003] However, axisymmetric aircraft are just a special case of symmetrical aircraft. Aircraft with high flight speeds (e.g., exceeding Mach 5) typically employ a symmetrical aerodynamic layout, i.e., they are symmetrical aircraft. During their flight, the coupling between their roll, yaw, and pitch channels is strong. The coupling characteristics between these channels can usually include inertial coupling characteristics, kinematic coupling characteristics, and aerodynamic coupling characteristics.

[0004] In existing systems, when most aircraft are hovering for cleaning, strong winds can interfere with the drone's hovering, thus affecting the cleaning of the photovoltaic panels. Furthermore, existing aircraft lack a power output mechanism that can compensate for flight attitude, and the existing power output mechanism does not have fine-tuning capabilities.

[0034] Example 1

[0035] Reference Figures 1-8This is the first embodiment of the present invention, which provides a flight attitude compensation power output mechanism for a jet cleaning drone, including a drone body 100. The drone body 100 is mainly used for cleaning photovoltaic panels. In this embodiment, the drone body 100 includes a drone main body 101, a flight control stick 102 disposed on the drone main body 101, and a wing assembly 103 disposed on the flight control stick 102. The drone main body 101 is the main structure of the drone, and the flight control stick 102 extends outward from the drone main body 101. In this embodiment, four flight control sticks 102 are provided, and the wing assembly 103 on each flight control stick 102 can increase lift, allowing the drone to perform take-off, landing, turning and other actions.

[0036] Preferably, in this embodiment, the flight control stick 102 is equidistantly arranged on the drone body 101, and the direction of the extended flight control stick 102 forms an angle with the horizontal direction, the angle being 15°-21°, preferably 20°, and the size of the end of the flight control stick 102 connected to the drone body 101 is larger than the end of the flight control stick 102 away from the drone body 101.

[0037] Furthermore, the wing assembly 103 includes a mounting cylinder 103a disposed at the end of the flight control stick 102, a drive motor disposed on the mounting cylinder 103a, and a drive blade 103b disposed on the drive motor. The mounting cylinder 103a is vertically arranged, and the motor shaft of the drive motor extends upward from the upper end of the mounting cylinder 103a. The drive blade 103b is directly connected to the drive motor, and the drive motor controls the drive blade 103b.

[0038] Furthermore, the main body 101 of the UAV is equipped with a wind direction monitoring module, a level module, and a main control module. The information synchronization module is connected to the main control module, and the main control module is equipped with a feedback module. The information synchronization module is used to synchronously calculate the current wind speed, liquid jet flow rate, and jet intensity of the jet tube 201b-1.

The jet power compensation component 201 can finely adjust and change the flight attitude of the UAV body 101. When the UAV body 101 is stably suspended for cleaning, if it is affected by external wind force and deviates, the jet power compensation component 201 is activated to maintain the suspension stability of the UAV.

[0040] Furthermore, the universal rotating component 202 mainly changes the orientation of the jet power compensation component 201. Furthermore, the present invention also includes a cleaning component 400, which is disposed at the lower end of the drone body 101.

[0041] Furthermore, in this embodiment, the jet power compensation component 201 includes a storage cavity 201a disposed at the lower end of the mounting cylinder 103a, and a jet component 201b disposed within the storage cavity 201a. An air supply pipeline is disposed inside the storage cavity 201a, and a gas storage tank is disposed on the UAV body 101. The gas storage tank is connected to the air supply pipeline, which extends into the jet component 201b.

[0042] Furthermore, in this embodiment, the injection component 201b includes an injection cylinder 201b-1 connected to the storage cavity 201a, a flame injector 201b-2 disposed in the injection cylinder 201b-1, and a reverse injection component 300 disposed on the injection cylinder 201b-1. The injection cylinder 201b-1 is provided with an air intake passage, and an air supply pipeline introduces compressed air into the air intake passage. A combustion chamber is also provided in the injection cylinder 201b-1, and a turbine is also provided in the air intake passage. The compressed air enters the combustion chamber and mixes with kerosene for combustion, generating high-temperature and high-pressure gas. The gas expands and performs work to drive the turbine to rotate at high speed. A nozzle is also provided at the end of the injection cylinder 201b-1. The high-temperature and high-pressure gas is ejected outward under the action of the turbine, and after being ejected, it can provide reverse thrust to the UAV.

[0043] Furthermore, the rear end of the spray cylinder 201b-1 is connected to the universal rotating component 202. The universal rotating component 202 includes an adjusting cylinder 202a rotatably connected to the rear end of the spray cylinder 201b-1 and a rotating plate 202b disposed at the rear end of the adjusting cylinder 202a. The rotating plate 202b is connected to the spray cylinder 201b-1, and the adjusting cylinder 202a can control and adjust the direction of the spray cylinder 201b-1, while the rotating plate 202b can drive the adjusting cylinder 202a to rotate. A drive stepper motor is disposed at the rear end of the rotating plate 202b, and the drive stepper motor can drive the rotating plate 202b to rotate.

[0044] Preferably, in this embodiment, the adjusting cylinder 202a includes a first rotating cylinder 202a-1 disposed on the rotating plate 202b, a second rotating cylinder 202a-2 rotatably connected to the first rotating cylinder 202a-1, inclined ports respectively opened at both ends of the second rotating cylinder 202a-2 and connected to the first rotating cylinder 202a-1 and the spray cylinder 201b-1, and rotating gears 202a-3 disposed at the rear ends of the second rotating cylinder 202a-2 and the spray cylinder 201b-1. Both the first rotating cylinder 202a-1 and the second rotating cylinder 202a-2 are provided with drive gears 202a-4 near the rotating gears 202a-3. The drive gears 202a-4 mesh with the rotating gears 202a-3. A drive motor is provided on the drive gears 202a-4. The drive motors are respectively disposed on the first rotating cylinder 202a-1 and the second rotating cylinder 202a-2.

[0045] The ports at both ends of the second rotating cylinder 202a-2 are inclined. When viewed from the side, the inclination angles of the two ports are the same, and the inclination angles of the two inclined ports are complementary, at 45° and 135° respectively. Consequently, the cross-sectional shape of the two inclined ports is circular. Therefore, when the drive motor drives the drive gear 202a-4 to rotate, it will cause the second rotating cylinder 202a-2 to rotate in the circular shape of the drive gear 202a-4. The direction is rotated around the circular surface of the tilted port. After rotation, the orientation of the second rotating cylinder 202a-2 changes. When the drive motor on the second rotating cylinder 202a-2 starts, it controls the drive gear 202a-4 on the spray cylinder 201b-1 to rotate, thereby adjusting the orientation angle of the spray cylinder 201b-1. By using the multi-segment structure, the port of the final spray cylinder 201b-1 can be rotated to any angle. When the spray cylinder 201b-1 applies thrust, it will adjust the tilt direction of the UAV body 101.

[0046] Furthermore, in this embodiment, the anti-spray component 300 includes a sliding guide rail 301 disposed on the spray cylinder 201b-1, a drive rod 302 slidably connected to the sliding guide rail 301, a plurality of first drive rods 303 and second drive rods 304 rotatably connected to the sliding guide rail 301, and a baffle 305 hinged to the ends of the first drive rods 303 and second drive rods 304. A guide rod 306 is disposed on the drive rod 302. There are four first drive rods 303 and four second drive rods 304. Every two first drive rods 303 and two second drive rods 304 are connected to a baffle 305. One first drive rod 303 and one second drive rod 304 are disposed on one side of a baffle 305. The first drive rod 303 is disposed at the end near the spray cylinder 201b-1, and the second drive rod 304 is disposed at the end away from the spray cylinder 201b-1.

[0047] Preferably, an electrically controlled cylinder 302c is provided at the rear end of the drive rod 302.

[0048] Furthermore, the baffle 305 includes a main baffle 305a and an arc-shaped baffle 305b disposed between the main baffle 305a. The lower end of the arc-shaped baffle 305b is provided with a sealing port. The arc-shaped baffle 305b is an arc-shaped plate with a certain curvature. The sealing port is mainly used to seal the ends after the two baffles 305 are joined. The sealing port is a rubber structure disposed on the arc-shaped baffle 305b.

[0049] Furthermore, a plurality of movable angle plates 307a are provided on the inner surface of the arc-shaped baffle 305b, and a circular groove 307b for installing each movable angle plate 307a is provided on the inner wall of the arc-shaped baffle 305b, and a connecting ball 307c is provided at one end of the movable angle plate 307a that extends into the circular groove 307b.

[0050] Preferably, a card 302a is provided on the second drive rod 304 near the sliding guide rail 301. A groove is formed on the guide rod 306, and a base block 302b is slidably connected in the groove. The card 302a extends from the second drive rod 304 and is hinged to the base block 302b. The length of the second drive rod 304 is greater than that of the first drive rod 303. The second drive rod 304 includes a stop rod 304a hinged to the sliding guide rail 301, an extension rod 304b slidably connected to the stop rod 304a, and a rotating rod 304c provided on the stop rod 304a. A rack 304d is placed on the extension rod 304b, and a micro gear 304e is set on the rotating rod 304c and meshes with the rack 304d. A micro motor is set at the end of the micro gear 304e away from the rotating rod 304c, and a connecting rod 304f extends outward from the side wall of the extension rod 304b and is connected to the rotating rod 304c. When the micro gear 304e is rotated by the micro motor at its end, the rack 304d will slide, thereby pushing the extension rod 304b outward, thus changing the included angle between the two baffles 305.

[0051] In this embodiment, the cleaning component 400 includes a water tank 401 disposed at the lower end of the drone body 101, a water nozzle 402 disposed on the water tank 401, a flow rate control valve disposed on the water nozzle 402, and a flow rate control module disposed on the flow rate control valve.

[0052] Furthermore, the wind direction monitoring module is electrically connected to the drive stepper motor and drive motor. An information synchronization module is set between the flow rate control module and the wind direction monitoring module. An information synchronization module is set on the main control module. A feedback module is set on the main control module. The information synchronization module is used to synchronously calculate the current wind speed, liquid jet flow rate and the jet intensity of the jet tube 201b-1, and feed the results back to the drive stepper motor and drive motor through the feedback module.

[0053] Operation process: When the drone is cleaning photovoltaic panels, if there is a significant impact from external wind, the following attitude compensation process will be adopted:

[0054] Current wind speed data is collected, and three-dimensional wind speed (V) is acquired at a frequency of 100Hz using a wind direction monitoring module (ultrasonic anemometer). x V y V z The system transmits the data to the information synchronization module in real time, and then the collected data is filtered by low-pass filter to remove high-frequency noise before entering the wind force level threshold determination stage.

[0055] Determine the wind force level threshold:

[0056] 1. Level 1 wind (3m / s < V ≤ 8m / s): When the outside horizontal wind speed exceeds 3m / s, the basic compensation mode is triggered, and the level module starts high-frequency attitude sampling to monitor pitch / roll angle deviation and yaw angle.

[0057] 2. Level 2 wind (8m / s < V ≤ 15m / s): If the outside horizontal wind speed exceeds 8m / s and the attitude deviation is greater than the set standard value of 2°, it is determined that strong wind compensation is required.

[0058] 3. Level 3 wind (V>15m / s): If a wind speed of >15m / s is detected for 10 consecutive seconds, the emergency mechanism is triggered, the cleaning component 400 prepares to shut down, and the emergency landing mechanism is triggered at the same time. The drone should quickly alert the operator.

[0059] All the above judgment results are transmitted to the main control module via the CAN bus, and the control parameter table of the corresponding compensation mode is activated at the same time.

[0060] During the compensation action, the attitude compensation component 200 is activated. The air intake is provided on the injection tube 201b-1, and the air supply line introduces compressed air into the air intake. A combustion chamber is also provided in the injection tube 201b-1, and a turbine is also provided in the air intake. The compressed air enters the combustion chamber and mixes with kerosene for combustion, producing high-temperature and high-pressure gas. The gas expands and does work to drive the turbine to rotate at high speed. A nozzle is also provided at the end of the injection tube. The high-temperature and high-pressure gas is ejected outward under the action of the turbine. After being ejected, it can provide reverse thrust to the injection nozzle.

[0061] At the same time, the wind direction, the spray force and direction of the water nozzle 402 of the cleaning component 400 are calculated and taken into account.

[0062] First, the compensation force model for the windward direction is calculated:

[0063] Based on the empirical formula of Bernoulli's equation, the compensation force F is calculated according to the current wind force level. comp :

[0064] Level 1 wind force: F comp =1.2×F wind (F) wind =0.5×ρ×V²×S, where ρ is the air density, S is the windward area (0.6 m²), and V is the wind speed.

[0065] Level 2 wind: F comp =1.5×F wind A 15% turbulence compensation coefficient is superimposed; the calculation results are synchronized to the jet direction solution module as input parameters for three-dimensional attitude adjustment.

[0066] Then, the three-dimensional parameters of the injection direction were calculated.

[0067] First, determine the orientation of the water nozzle 402. The orientation of the water nozzle 402 is the rotation angle of the motor at the rear end of the water nozzle 402.

[0068] Determine the direction and angle of the wind, the pitch angle Δφ: by Δφ = arcsin(V z / V) Calculate the vertical compensation angle, with an adjustment range of -30° to +30°;

[0069] Flow rate control: The injection flow rate is determined by referring to a table based on the wind force level, and the opening of the gas flow valve is adjusted by a PWM signal.

[0070] After determining the required compensation angle and force, the drive motor inside the universal rotating component 202 drives the drive gear 202a-4 to rotate, which in turn causes the rotating gear 202a-3 on the first rotating cylinder 202a-1 or the second rotating cylinder 202a-2 to rotate. As shown in the attached drawings, the rotating gear 202a-3 is set at a certain angle, so that the rotation angle of the rotating gear 202a-3 is not along the axial direction of the first rotating cylinder 202a-1 or the second rotating cylinder 202a-2. When the rotating gear 202a-3 on the first rotating cylinder 202a-1 rotates, the second rotating cylinder 202a-2 rotates along the axial direction of the side of the rotating gear 202a-3. After rotation, the second rotating cylinder 202a-2 changes from being in a straight line with the first rotating cylinder 202a-1 to being perpendicular to it.

[0071] The aforementioned adjustments will change the orientation of the injection tube 201b-1, thereby causing a change in the thrust direction.

[0072] When small-angle fine-tuning or compensation in a certain direction is required, the electronically controlled cylinder 302c controls the sliding of the drive rod 302. As the drive rod 302 slides down, it drives the first drive rod 303 and the second drive rod 304 to swing outward. During the swing, the baffle 305, which was originally against the spray tube 201b-1, swings from the direction close to the spray tube 201b-1 to the position at the lower end of the spray tube 201b-1, and the two baffles 305 come together. At this time, the gas ejected from the spray tube 201b-1 will be blocked by the two baffles 305, thereby reducing the spray force of the spray tube 201b-1. Furthermore, due to the force of the gas impacting the baffles 305, the UAV will undergo a slight deflection and displacement in the opposite direction of the spray tube 201b-1.

[0073] Meanwhile, several movable angle plates 307a are also provided on the baffle 305. When the spray tube 201b-1 impacts the movable angle plate 307a, the movable angle plate 307a will rotate at a certain angle.

[0074] By utilizing the aforementioned structure and control logic, comprehensive control of the drone's airframe stability can be achieved when it is working in windy conditions. This ensures that the impact of external wind on the airframe can be reduced and flight stability can be maintained when performing tasks such as cleaning or other tasks like handling.
