Description

Technical Field

[0001] The present invention relates to the technical field of attitude compensation power output mechanisms, and in particular to a flight attitude compensation power output mechanism for a jet cleaning UAV. Background Art

[0002] During flight, an aircraft's flight 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 effect of this coupling on the aircraft's flight attitude can be treated as a random small perturbation, allowing the construction of a small-disturbance aerodynamic model for the aircraft. Currently, based on this small-disturbance aerodynamic model, three independent attitude controllers are typically deployed within an axisymmetric aircraft, one for controlling the angular velocity of the pitch, yaw, and roll channels, respectively.

[0003] However, axisymmetric aircraft are only a special case of plane-symmetric aircraft. Aircraft flying at higher speeds (e.g., exceeding Mach 5) typically adopt a plane-symmetric aerodynamic layout. During flight, the coupling between the roll, yaw, and pitch channels is strong. Typical coupling characteristics between these channels include inertial, kinematic, and aerodynamic coupling.

[0004] In the existing situation, when most aircraft are hovering for cleaning, if the external wind is too strong, the wind will interfere with the hovering of the drone, which in turn affects the cleaning of the photovoltaic panels. The existing aircraft lacks a power output mechanism that can compensate for the flight posture, and the existing power output mechanism does not have a fine-tuning function.

The compressed air enters the combustion chamber and mixes with kerosene to burn, generating high-temperature and high-pressure gas. The expansion work drives the turbine to rotate at high speed. A nozzle is also provided at the end of the injection tube 201b-1. The high-temperature and high-pressure gas is ejected outward under the action of the turbine, and after being ejected, it can give the drone reverse thrust.

[0043] Furthermore, the rear end of the injection cylinder 201b-1 is connected to the universal rotating component 202, and the universal rotating component 202 includes an adjusting cylinder 202a rotatably connected to the rear end of the injection cylinder 201b-1, and a rotating plate 202b arranged at the rear end of the adjusting cylinder 202a.

The information synchronization module is used to synchronously calculate the current wind speed, liquid injection flow rate and injection intensity of the injection tube 201b-1, and feed back the obtained results to the driving stepper motor and the driving motor through the feedback module.

[0053] Operation process: When the drone is performing photovoltaic panel cleaning operations, if the external wind force has a strong impact, the following attitude compensation process will be adopted:

[0054] The current wind speed data is collected by using the wind direction monitoring module (ultrasonic wind speed sensor) to collect three-dimensional wind speed (V x ,V y ,V z ), and transmit the data information to the information synchronization module in real time. The collected data is then low-pass filtered to remove high-frequency noise and enter the wind force level threshold determination link.

[0055] Determine the wind force level threshold:

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

[0057] 2. Level 2 wind force (8m / s<V≤15m / s): If the external 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 speed (V>15m / s): If the wind speed is detected to be >15m / s for 10 seconds continuously, the emergency mechanism will be triggered, the cleaning component 400 will be ready to shut down, and the emergency landing mechanism will be quickly 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 corresponding to the compensation mode is activated at the same time.

[0060] When performing the compensation action, the posture compensation component 200 is started, and the air intake duct is provided on the injection tube 201b-1. The air supply pipeline introduces compressed air into the air intake duct. A combustion chamber is also provided in the injection tube 201b-1. At the same time, a turbine is also provided in the air intake duct. The compressed air enters the combustion chamber and mixes with kerosene to burn, generating high-temperature and high-pressure combustion gas. The expansion work drives the turbine to rotate at high speed. A nozzle is also provided at the end of the injection pipe. The high-temperature and high-pressure combustion gas is ejected outward under the action of the turbine, and after being ejected, it can give the injection pipe a reverse thrust.

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

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

[0063] Based on the empirical formula of Bernoulli 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, ρ is air density, S is windward area (0.6 m²), and V is wind speed);

[0065] Level 2 wind force: F comp =1.5×F wind , superimpose a 15% turbulence compensation coefficient; synchronize the calculation results to the injection direction solution module as the input parameters for three-dimensional posture adjustment.

[0066] Then solve the three-dimensional parameters of the injection direction

[0067] First, determine the direction of the water nozzle 402. The direction 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) calculates the vertical compensation angle, with an adjustment range of -30° to +30°;

[0069] Flow rate control: Determine the injection flow rate according to the wind force level table, and adjust the gas flow valve opening through the PWM signal.

[0070] After determining the angle and force that need to be compensated, the driving motor in the universal rotating component 202 is used to drive the rotation of the driving gear 202a-4, and then the rotating gear 202a-3 on the first rotating cylinder 202a-1 or the second rotating cylinder 202a-2 is rotated. It can be seen from the drawings in the specification that the setting of our rotating gear 202a-3 has 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 the rotation, the second rotating cylinder 202a-2 changes from the original straight line direction with the first rotating cylinder 202a-1 to the vertical direction.

[0071] The above adjustment will change the orientation of the jet tube 201b-1, thereby changing the thrust direction.

[0072] When fine-tuning of a small angle is required and compensation is required in a certain direction, the electric control cylinder 302c is used to control the sliding of the driving rod 302, so that the driving rod 302 slides down while driving the first driving rod 303 and the second driving rod 304 to swing outward. When swinging out, the baffle 305 originally leaning on the injection tube 201b-1 will be driven to swing from the direction close to the injection tube 201b-1 to the lower end position of the injection tube 201b-1, and the two baffles 305 are brought together. At this time, the gas ejected from the injection tube 201b-1 will be blocked by the two baffles 305, thereby reducing the injection force of the injection tube 201b-1 accordingly, and because of the force of the gas impacting the baffle 305, the drone will undergo a slight deflection and displacement in the opposite direction of the injection tube 201b-1.

[0073] At the same time, a number of movable angle plates 307a are provided on the baffle 305. When the jet tube 201b-1 impacts the movable angle plate 307a, the movable angle plate 307a will rotate at a certain angle.

[0074] By utilizing the above structure and control logic, comprehensive control of the drone's fuselage stability can be achieved when the drone is performing work in windy weather. This ensures that the impact of wind on the fuselage can be reduced and flight stability can be maintained when performing cleaning or other tasks such as transportation.
