Description

Technical Field

[0001] The present invention relates to the field of laser application technology, in particular to a laser-microwave composite deicing system and method. Background Art

[0002] Wind power plants and high-voltage power lines are mostly located in high-altitude cold areas such as plateaus, ridges, and mountain tops, as well as high-latitude areas with rich wind energy resources. Due to the high altitude and low temperature, wind turbine blades and high-voltage power lines in these areas are prone to ice in winter; and when the blades or high-voltage power lines are frozen, not only will the load increase, affecting the life of the blades or the normal operation of the high-voltage power lines, but also when the ice is severe, the unit will have to be disconnected from the grid or the high-voltage power lines will be broken, which greatly reduces the utilization rate of the units in low-temperature areas for a long time. In addition, after the blades or high-voltage power lines are frozen, as the temperature rises, the ice will fall off, which will not only cause great safety hazards to the units and on-site personnel, but also when the blades or high-voltage power lines are severely iced, the blades or high-voltage power lines will be broken, thereby threatening the safety of personnel in wind farms or substations; at the same time, when the blades are covered with ice, the efficiency of the unit will be reduced, resulting in an annual power generation loss of 1%-10%, and in areas with harsh conditions, the annual power generation loss may even reach 20%-50%.

[0003] At present, there are many ways to de-ice wind turbine blades, such as mechanical de-icing, thermal de-icing, chemical spray de-icing, ultrasonic vibration de-icing, electromagnetic pulse de-icing, etc. However, these are passive de-icing methods based on heat, electricity, manpower, etc., which are not only time-consuming, labor-intensive, energy-consuming, and inefficient, but also costly and cannot fundamentally solve the above problems. Summary of the invention

[0004] In view of the problems in the background technology, the purpose of the present invention is to provide a laser-microwave composite deicing system and method to achieve large-area and efficient removal of ice from the surfaces of wind turbine blades, high-voltage wires and other objects.

S2, performing analog calculation in the integrated control system (104) according to the ice-covered area and ice thickness signals fed back by the photoelectric sensor (107), and presetting corresponding operating parameters of the laser light source (102), the microwave power source (103) and the microwave absorbing material spraying device (108); S3, controlling the laser light source (102) to output a pulsed laser beam through the integrated control system (104), and then obtaining a pulsed wide-width laser spot after being collimated by the collimation adjustment system (105) and the scanning system (109), and then acting on the ice layer (114) on the surface of the deicing target (113) according to a path preset by the system, and forming small honeycomb-shaped gaps on the surface of the ice layer (114); S4, after water and small gaps appear on the surface of the ice layer (114), the integrated control system (104) controls the absorbing material spraying device (108) to spray the absorbing material (115) onto the surface of the ice layer (114) and the gaps in the ice layer (114) of the deicing target (113); S5, using a photoelectric sensor (107) to detect in real time the adsorption of the absorbing material (115) on the surface of the ice layer (114) of the deicing target (113) and in the gaps of the ice layer (114); When the photoelectric sensor (107) detects that the absorbing material (115) is adsorbed on the surface of the ice layer (114) and in the gaps of the ice layer (114), the laser light source (102) is controlled to operate through the integrated control system (104) to generate continuous laser light, and then a wide continuous laser beam surface is obtained through the scanning system (109) and acts on the surface of the ice layer (114); at the same time, the microwave power source (103) is controlled to operate through the integrated control system (104) to generate microwave power, which is converted into microwave energy by the magnetron system (106) and then radiated to the ice layer (114) on the surface of the deicing target (113) through the heating antenna (110); S6, repeating steps S1 to S5 until the entire ice layer (114) on the surface of the deicing target (113) is removed; During deicing, the scanning system (109) is 2 to 4 meters away from the ice layer (114) on the surface of the deicing target (113); and the heating antenna (110) is 2 to 5 meters away from the ice layer (114) on the surface of the deicing target (113).
