Description

Technical Field

[0001] The utility model relates to the technical field of ice removal for wind turbine blades, and particularly relates to an unmanned aerial vehicle for ice removal of wind turbine blades. Background Technique

[0002] In areas with low temperatures and high humidity, ice is likely to form on the surfaces of the blades of wind turbines. This icing not only reduces the power generation efficiency but also changes the rotational counterweight of the blades, thus posing a potential threat to the safety of the equipment. Since the blades of wind turbines are located at a high altitude, it poses an additional challenge to clean them to remove the ice. Most of the existing technologies use unmanned aerial vehicles for high-altitude ice removal operations. However, for specially designed ice removal unmanned aerial vehicles, they are only used in extreme weather conditions in a year and are idle at ordinary times, which greatly affects the practicality of the unmanned aerial vehicles. Taking the prior art represented by a comparative document, an unmanned aerial vehicle for ice removal of wind turbine blades (publication number CN220337010U) as an example, in this patented technology, an ice remover spraying assembly is provided for spraying ice remover on the ice layer on the wind turbine blades, a hot air blowing assembly is provided for blowing air on the ice layer on the wind turbine blades, the power supply device includes a photovoltaic panel and a battery, and both the ice remover spraying assembly and the hot air blowing assembly are electrically connected to the battery so that the battery can supply power to the ice remover spraying assembly and the hot air blowing assembly. At least part of the photovoltaic panel is arranged on the top surface of the aircraft body, and the photovoltaic panel is electrically connected to the battery so that the photovoltaic panel can use solar energy to charge the battery. Since the battery is connected to the photovoltaic panel, during the ice removal process of the unmanned aerial vehicle, the photovoltaic panel can use solar energy to charge the battery, thereby improving the endurance time of the unmanned aerial vehicle, increasing the ice removal working hours of the unmanned aerial vehicle, and improving the ice removal efficiency. Different ice removal methods can be selected according to different ice layer thicknesses, thus effectively solving the problems of the existing technology. However, its structure still needs to be improved, specifically as follows:

[0003] In this solution, when the unmanned aerial vehicle removes ice from the wind turbine blades, the photovoltaic panel can use solar energy to charge the battery, thereby improving the endurance time of the unmanned aerial vehicle. However, the effect that this method can bring is very limited. The area of the wind turbine blades is very large, and long-term hovering operations are required. The volume of the unmanned aerial vehicle is very small, and the power generation power of the solar panel of the same volume is very low, which simply cannot meet the normal operation of the flight of the unmanned aerial vehicle, as well as the spraying assembly and the hot air blowing assembly. The practicality is poor. Therefore, an unmanned aerial vehicle for ice removal of wind turbine blades is needed to improve the above problems. Content of the Utility Model

An outdoor power supply 213 is installed on the outer wall of the portable cable winder 212.

[0026] In this embodiment, specifically refer to Figure 1 , Figure 2 and Figure 5 , the fixing assembly 3 includes an upper bracket 301 and a lower bracket 302. The upper bracket 301 is attached to the outer wall of the airframe 1. A rubber pad 303 is installed on the outer wall of the upper bracket 301 directly above the airframe 1. There are multiple groups of rubber pads 303 which are respectively located on the outer wall of the upper bracket 301. The material of the rubber pad 303 is rubber material. The lower bracket 302 is installed on the outer wall of the upper bracket 301 through bolts 304. Both the upper bracket 301 and the lower bracket 302 are of frame structure.

[0027] Among them, the lower bracket 302 is embedded and installed on the inner wall of the installation housing 201. Under the action that the control panel 7 is respectively connected to the brushless motor 5, the infrared distance measuring sensor 202, the small hot air blower 203, the micro sprayer 204 and the outdoor power supply 213 through wires and the connection method is electrically connected, the device is powered on. There are multiple groups of brushless motors 5 which are respectively located on the outer wall of the installation bracket 4. The bottom of the installation bracket 4 is lower than the bottom of the installation housing 201. Under the action that the limiting spring 206 is located in the middle of the inner cavity of the installation housing 201, when the body 1 is on the ground, the counterweight 209 is on the ground, the tension of its sleeve 207 is lost, and the stretched limiting spring 206 retracts, and the device resets. The connection between the second conduit 210 and the installation housing 201 is a communicating structure. There are two groups of connecting rods 208 which are respectively located on the outer wall of the sleeve 207. The sleeve 207 is located between the first conduit 205 and the second conduit 210. The counterweight 209 is located directly below the installation housing 201. One end of the conduction wire 211 is connected to the outdoor power supply 213 through the portable reel 212, and the other end of the conduction wire 211 is connected to the body 1. The outdoor power supply 213 is located directly below the body 1.

[0028] When the unmanned aerial vehicle for deicing the blades of a wind turbine unit in this solution is working, the upper bracket 301 fits on the outer wall of the body 1. A rubber pad 303 is installed on the outer wall of the upper bracket 301 directly above the body 1. The lower bracket 302 is installed on the outer wall of the upper bracket 301 through bolts 304. Under the action that the lower bracket 302 is embedded and installed on the inner wall of the installation housing 201, when in use, only need to fit the upper bracket 301 on the outer wall of the body 1, then align the lower bracket 302 with the upper bracket 301, and install the bolts 304 on the outer walls of the upper bracket 301 and the lower bracket 302 in sequence for fixation, so that the deicing assembly 2 is fixed at the bottom of the body 1. Only when in use, it is necessary to install the deicing assembly 2, and usually it can be used as an ordinary unmanned aerial vehicle, thus solving the problem that the deicing unmanned aerial vehicle is only used in extreme weather in a year and is idle usually, which greatly affects the practicability of the unmanned aerial vehicle.

[0029] An infrared distance sensor 202 is installed on the opposite side walls of the installation housing 201. Under the action of the small hot air blower 203 embedded in the outer wall of the installation housing 201, the brushless motor 5 is controlled to operate through the control panel 7, and then the brushless motor 5 takes off through the propeller 6. When the aircraft body 1 takes off, one end of the conduction wire 211 is connected to an outdoor power supply 213 through a portable winder 212, and the other end of the conduction wire 211 is connected to the aircraft body 1. With the outdoor power supply 213 located directly below the aircraft body 1, the outdoor power supply 213 supplies power to the aircraft body 1 through the conduction wire 211, enabling the drone to stay in the air for a long time. At the same time, a first conduit 205 is installed on the inner wall of the installation housing 201, and a limiting spring 206 is installed on the inner wall of the installation housing 201. One end of the limiting spring 206 is installed with a sleeve 207, and a counterweight 209 is installed at the bottom of the sleeve 207 through a connecting rod 208. A second conduit 210 is installed on the side wall of the installation housing 201, and a conduction wire 211 is installed on the inner wall of the first conduit 205. One end of the conduction wire 211 sequentially passes through the sleeve 207 and the second conduit 210, and one end of the conduction wire 211 is installed with a portable winder 212. When the aircraft body 1 takes off, the conduction wire 211 is pulled out from the portable winder 212, thereby increasing the flight range of the drone. Since the wire will swing with the wind when it is too long, when the aircraft body 1 takes off, the counterweight 209 moves downward under the action of gravity, and the counterweight 209 pulls the conduction wire 211 downward through the sleeve 207, thereby tightening the conduction wire 211 and reducing the shaking. Then, the switch is turned on to enable the small hot air blower 203 and the micro sprayer 204 to cooperate to de-ice the wind turbine blades. The working range of the device is larger, and due to ground power supply, its hovering time is longer, greatly meeting the working requirements, thus solving the problems that the volume of the drone is very small, the power generation power of the solar panel of the same volume is very low, and it simply cannot meet the flight of the drone, as well as the normal operation of the spraying component and the hot air blowing component, and the practicability is poor.
