Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of power equipment deicing, especially relates to unmanned plane microwave deicing device. BACKGROUND

[0002] In recent years, with the further expansion of rail transit construction, especially the continuous expansion of electrified railways, in high-latitude and high-cold regions and some low-latitude microtopography and microclimate icing areas, the electrified railway catenary is easily affected by icing, and the icing problem of the electrified railway catenary will destroy the safety and stability of the transportation industry, causing unstable power supply of the railway, and even direct power failure, endangering the power supply loop of the entire electrified track, and in serious cases, causing train stoppage or personal safety accidents.

[0003] However, the current traditional deicing methods are mainly divided into mechanical deicing method, alternating current short circuit current deicing method, direct current short circuit deicing method and natural deicing method, but these deicing methods have the following shortcomings:

[0004] Mechanical deicing method: mainly through the site situation, using artificial knocking, gun shooting or even using helicopters and other methods for deicing, such method has low safety and deicing efficiency, and is easy to cause damage to power facilities.

[0005] Alternating current short circuit current deicing method: alternating current short circuit deicing can directly use system power to provide short circuit current, which is convenient to operate and has relatively low cost, and is the most commonly used deicing method at present, but it takes a long time and has certain harm to the circuit.

[0006] Direct current short circuit deicing method: the mobile direct current deicing device is composed of alternating current power supply system, rectifier transformer, controllable silicon rectifier power supply and control protection system, etc. These devices can be placed on a flat car and moved with the car, so they can complete the deicing of any section of overhead line, but the economic cost is high and the loss is large.

[0007] Natural deicing method: natural deicing method refers to the method of realizing deicing by natural force without external energy. When the snow or icing reaches a certain degree, it relies on wind power, gravity and other actions to fall off by itself. This method is simple and easy to operate, but has strong contingency and cannot prevent ice formation, but can help limit ice disasters. Common natural deicing methods include using counterweight, snow ring deicing and using hydrophobic coating to prevent ice. It takes a long time and cannot solve the problem in time.

[0008] With the rapid development of unmanned aerial vehicle technology, it gradually emerges in the special working condition operation field with the advantages of strong maneuverability, flexible operation, no need for personnel high altitude operation, etc. At the same time, the microwave heating technology rises, the microwave can penetrate the ice layer, make the water molecules vibrate, friction heat, efficient melting ice layer, and will not cause mechanical impact to the equipment body, combine the unmanned aerial vehicle with the microwave technology, make the unmanned aerial vehicle microwave deicing device, become the innovative direction to solve the current deicing problem, however, the existing unmanned aerial vehicle equipment scheme is mostly simple structure, unstable mounting, the microwave generator cannot accurately aim at the deicing target, the power supply and signal transmission are unstable, it is difficult to meet the actual deicing demand in the complex outdoor environment; The navigation accuracy is insufficient, so that the unmanned aerial vehicle is difficult to stably reach the specified deicing position; The protection measure is lacking, and the key components are easy to be eroded and damaged by bad weather.

[0009] Therefore, it is urgent to develop an efficient, stable, safe and practical unmanned aerial vehicle microwave deicing device to overcome the bottleneck of the prior art. Practical new type content

[0010] One purpose of the present application is to provide an unmanned aerial vehicle microwave deicing device, which can efficiently, accurately and flexibly remove the ice layer on the surface of various targets, especially suitable for areas such as power lines, communication base station antennas, high buildings, etc. The ice on the top of the area is difficult to remove by conventional methods, greatly improving the safety and convenience of deicing operation.

[0011] According to the unmanned aerial vehicle microwave deicing device provided by the embodiment of the present application, the unmanned aerial vehicle is used as the air carrier of the whole device, and the mounting rack at the bottom and the mounting seat form a stable and convenient mounting structure. The plug-in block integrally formed on the inner wall of the mounting rack is inserted into the symmetrical insertion slot opened on the outer wall of the mounting seat, so that the preliminary positioning and connection are realized. Then, the limiting block movably installed in the limiting frame of the rear wall of the mounting rack can be accurately adjusted and fixed in position through the bolt penetrating the long strip-shaped perforation and being screwed into the screw hole, so that the displacement of the mounting seat during flight and operation is effectively prevented, and the stability of the microwave generator is ensured.

[0012] The microwave generator is rotatably installed at the bottom of the mounting seat through the shaft, and the worm is vertically rotatably installed in the worm housing on one side of the outer wall of the bracket. Under the driving of the servo motor at the top of the worm housing, the worm is meshed with the worm wheel fixed outside the shaft of the microwave generator, so that the angle of the microwave generator is accurately adjusted. This design enables the microwave generator to flexibly adjust the orientation of the horn-shaped radiation antenna according to the shape, position and deicing demand of different targets, efficiently focus the microwave energy on the area to be deiced, and improve the deicing effect and efficiency.

[0013] Further, the four fixedly installed propellers around the unmanned aerial vehicle are driven by motors to provide reliable lift and flight power for the unmanned aerial vehicle, so that it can stably fly in different environments and reach the deicing operation site. The two legs on the bottom side play a buffering and supporting role when the unmanned aerial vehicle lands, protecting the equipment from damage caused by ground impact.

[0014] Further, the camera installed below the front side of the unmanned aerial vehicle can collect image information of the operation area in real time, and the operator can accurately determine the target position, ice layer condition and surrounding environment according to the image information, so as to reasonably plan the flight path and deicing operation. The fog lamps symmetrically installed on both sides of the camera at the bottom front side effectively enhance the visibility of the front area in low-visibility environments such as fog, rain and snow, ensuring flight safety and assisting in identifying deicing targets.

[0015] Further, the power battery arranged inside the unmanned aerial vehicle provides power support for the entire device, and the power signal interface arranged at the bottom rear side of the power battery corresponds to the power signal interface arranged at the bottom rear side of the mounting seat. The connection through the wire harness with the connector not only realizes stable power supply to the microwave generator, but also enables data signal transmission, which is convenient for the control system of the unmanned aerial vehicle to monitor and control the working state of the microwave generator, such as adjusting the microwave power, emission frequency and other parameters, to adapt to different deicing task requirements.

[0016] Further, the design that the limiting block can slide horizontally in the limiting frame and the bolt can slide horizontally in the long strip-shaped perforation enhances the adaptability and adjustment accuracy of the mounting structure, which can effectively cope with mounting seats of different sizes or manufacturing tolerances, ensuring tight and reliable connection and fixation.

[0017] Further, the protective cover fixedly installed outside the worm holder, worm, worm gear and servo motor on the side wall of the bracket effectively blocks the erosion and interference of external dust, debris, rainwater and the like on the transmission and driving components, reduces the probability of component wear and failure, improves the reliability and durability of the angle adjustment mechanism of the microwave generator, and ensures long-term stable operation of the entire deicing device.

[0018] Further, the corrosion-resistant coating coated on the surface of the horn-shaped radiating antenna adopts ceramic-based composite coating material with a thickness of 0.1-0.3 millimeters. The coating has excellent corrosion resistance, wear resistance and high-temperature resistance, which can effectively protect the horn-shaped radiating antenna from erosion by external environmental factors in various complex and harsh climate environments, such as high humidity and strong acid and alkali atmospheric environments, prolong the service life of the horn-shaped radiating antenna, ensure the stability and reliability of microwave emission, and thus continuously and stably output microwave energy for deicing operation.

[0019] Further, the flight control system of the unmanned aerial vehicle is integrated with a high-precision GPS module and a Beidou navigation module, and the two modules can be switched or cooperated with each other. In the normal flight operation process, the GPS module can provide accurate global positioning information, so that the unmanned aerial vehicle can fly according to the preset route. When the GPS signal is disturbed or the positioning accuracy is reduced in a specific area, the Beidou navigation module can be quickly switched in or cooperated with the GPS module for data fusion and correction, so that the unmanned aerial vehicle can be accurately positioned and stably flown to the target deicing area, and accurate flight guidance and position guarantee are provided for the whole deicing operation.
