Description

Technical Field

[0001] This invention belongs to the field of power supply device technology, and in particular relates to a hybrid power supply device for photovoltaic, wind power and energy storage batteries. Background Technology

[0002] With the rapid development of distributed microgrids, field monitoring, communication base stations, and independent power supply in remote areas, small-scale photovoltaic, wind power, and energy storage battery hybrid power supply devices have been widely used due to their advantages such as energy complementarity, clean and environmentally friendly operation, and flexible installation. These devices typically consist of a small wind turbine, photovoltaic modules, energy storage batteries, and a charge and discharge control system, enabling wind and solar power generation, energy storage, and stable output, effectively improving power supply reliability and environmental adaptability.

[0003] During long-term operation, the blades of small wind turbines are constantly exposed to the complex outdoor natural environment. They are subjected to continuous alternating wind loads, sudden strong wind impacts, dust particle erosion, rain, snow, ice erosion, thermal expansion and contraction caused by diurnal temperature differences, and material fatigue aging. These factors make them highly susceptible to developing microcracks in stress concentration areas on the blade surface. These cracks are initially small and hidden, making them difficult to detect visually through manual inspections during normal operation. As the operating time increases, the cracks will continue to expand under the repeated action of wind loads and environmental stresses, leading to a decrease in the structural strength of the blades, deterioration of aerodynamic performance, increased unit vibration, increased noise, and a significant reduction in power generation efficiency. If the cracks continue to expand and are not addressed in time, they may cause blade breakage, unit imbalance and damage, and thus affect the stable operation of the entire wind-solar-storage hybrid power supply system, and even cause safety hazards and economic losses such as equipment damage and power outages.

A limit electric push rod 59 is connected to the support rod 2 through a bracket. A limit arc plate 60 is fixedly connected to the moving end of the limit electric push rod 59.

[0023] The operating principle of this invention is explained as follows: When the control cabinet 3 collects the output voltage, output current, power generation and light intensity parameters of the photovoltaic panel 5 in real time, it compares and analyzes the actual power generation with the theoretical power generation under the same light conditions. When it is detected that the actual power generation is significantly lower than the theoretical power generation and the difference continues to exceed the set threshold, it can be determined that the photovoltaic panel 5 has reduced photoelectric conversion efficiency due to excessive dust coverage. The control cabinet 3 will then control the valve inside the connecting pipe 13 to open (the valve is not shown in the figure). Since the pressure inside the water tank 111 is relatively high at this time, the flushing liquid will be transported to the flushing pipe 112 through the connecting pipe 13 under pressure and sprayed out through the spray head 12. The spray head 12 is used to wash the dust attached to the surface of the photovoltaic panel 5, thereby ensuring the working efficiency of the photovoltaic panel 5. When control cabinet 3 detects that the internal pressure of water tank 111 has dropped to a set threshold (standard atmospheric pressure) via pressure sensor (not shown in the diagram), control cabinet 3 will close the valve inside connecting pipe 13. Simultaneously, the controller will operate the small motor 142, which will rotate the air cylinder 15 below the arc-shaped plate 24. When a strong wind causes the fan blade 10, guide seat 9, and drive shaft 8 to rotate, the drive shaft 8 will rotate the arc-shaped plate 24 as well. After the arc-shaped plate 24 rotates above the air cylinder 15, it contacts the arc seat 17. The arc seat 17, through the pressure rod 16, will cause the piston plate 18 to move downwards, compressing the gas below the air cylinder 15. The gas is delivered to the accumulator 141 through the hose 20 and the one-way valve 21 on this side, and then to the conduction cylinder 22 through the vent on the surface of the accumulator 141. The gas is then delivered to the water tank 111 through the metal pipe 23, which increases the internal pressure of the water tank 111. When the arc plate 24 and the arc seat 17 separate, under the action of the spring force, the piston plate 18 will drive the arc seat 17 to move upward through the pressure rod 16. The external gas will enter the inflation cylinder 15 through the air inlet pipe 19 and the one-way valve 21 on this side. When the control cabinet 3 detects that the internal pressure of the water tank 111 reaches the set threshold (0.2MPa) through the pressure sensor, it will control the small motor 142 to drive the inflation cylinder 15 to separate from the arc plate 24. When a crack occurs on the surface of a fan blade 10, the high-pressure gas in the hollow cavity 252 will be discharged to the outside through the crack. The gas inside the detection cavity 251 will be discharged together through the connecting hole 26, thereby reducing the gas pressure on the side of the piston block 31 close to the trigger switch 30. The piston block 31 will then move the pressure plate 29 through the vertical rod 28, and the pressure plate 29 will squeeze the trigger switch 30. The trigger switch 30 will then send an electrical signal to the control cabinet 3, indicating that a crack has appeared on the surface of the fan blade 10. The control cabinet 3 first detects the deflection angle of the rotating rod 6 through the encoder between the support rod 2 and the rotating rod 6. Then, it controls the drive motor 35 to work. The drive motor 35 drives the rotating ring 332 to rotate through the gear ring transmission assembly (the gear ring transmission assembly includes drive teeth connected to the output end of the drive motor 35 and a gear ring sleeved on the outside of the rotating ring 332. The drive motor 35 can drive the gear ring and the rotating ring 332 to rotate through the drive teeth). The rotating ring 332 drives the positioning screw linear module 37, the lifting rod 38 and the repair assembly 40 to rotate to the set position through the bending plate 36, so that the orientation of the bending plate 36 is the same as the orientation of the guide seat 9. Then, the control cabinet 3 controls the limit electric push rod 59 to work. The limit electric push rod 59 fixes the angle of the rotating rod 6 through the limit arc plate 60. The control cabinet 3 also controls the brake hydraulic cylinder 55 to work. 55 drives the friction plate 56 to move, so that the friction plate 56 and the brake pad 54 come into contact. The friction between the friction plate 56 and the brake pad 54 reduces the rotational speed of the drive shaft 8, thereby reducing the impact of strong winds on the rotational speed of the drive shaft 8. Subsequently, the geared motor in the engine compartment 7 (the geared motor is located inside the engine compartment 7 and is not shown in the figure. The geared motor is a non-brake motor and is connected to the drive shaft 8 through a gear ring transmission mechanism) will drive the drive shaft 8 to rotate slowly. During the rotation of the drive shaft 8, the control cabinet 3 will control the laser generator 57 and the corresponding laser receiver 58 to work. When the laser signal emitted by the laser generator 57 is received by the corresponding laser receiver 58, the control cabinet 3 will detect this situation and control the geared motor to stop working immediately, and control the brake hydraulic cylinder 55 to work further. Based on the above principle, the drive shaft 8 will stop rotating immediately. Next, the control cabinet 3 controls the sealing electric push rod 50 to separate the sealing plates 52 on both sides from the surface of the repair frame 401. The controller controls the positioning screw linear module 37 to work. The positioning screw linear module 37 drives the repair frame 401 to move slowly upward through the lifting rod 38 and the crossbar 39. The control cabinet 3 also controls the small screw linear modules 43 and the micro electric push rod 44 on both sides inside the repair frame 401 to work. The micro electric push rod 44 drives the detection probe 47 to contact the fan blade 10, while the small screw linear module 43 drives the detection probe 47 to slide along the surface of the fan blade 10. When the control cabinet 3 detects a crack on one side of the fan blade 10 through the detection probe 47, the control cabinet 3 controls the metering pump 42 and the control valve 49 on one side to work. The metering pump 42 delivers the glue stored in the storage box 402 through the delivery channel 41 and the elastic tube 48 to the corresponding spray nozzle 46 and sprays it out, thus repairing the crack.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
