[0002] Existing photovoltaic power generation technology usually uses solar photovoltaic panels for photovoltaic power generation. For high-latitude areas or areas with heavy snow in winter, photovoltaic panels are prone to snow accumulation and affect power generation efficiency, and thus the snow on the surface of the photovoltaic panels needs to be cleaned. Related technologies include using drones to fly onto the surface of photovoltaic panels and use brushes to clean the snow on the surface of the photovoltaic panels. However, this method cannot completely clean the snow, and a small amount of snow is likely to remain on the photovoltaic panels. Utility Model Content

[0025] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0026] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to the inside and outside relative to the outline of the structure or component itself; "first, second" and the like are intended to distinguish one element from another and have no order or importance. In addition, the same figure marks in different reference drawings represent the same elements.

[0027] The present invention provides a drone, referring to Figures 1 to 6 As shown, the UAV includes a fuselage 1, a heating mechanism 2 and a blower mechanism 3. The heating mechanism 2 is arranged at the bottom of the fuselage 1 and includes a microwave transmitter 210. The microwave transmitter 210 is used to transmit microwaves to the snow on the photovoltaic panel. The blower mechanism 3 is arranged at the bottom of the fuselage 1 and includes a fan and a heating element. The fan is used to blow the air heated by the heating element to the snow on the photovoltaic panel.

[0028] Through the above-mentioned method, that is, the drone provided by the present invention, when the drone is used to clean the snow on the surface of the photovoltaic panel, the heating mechanism 2 and the blowing mechanism 3 can work together. For example, the microwave transmitter 210 of the heating mechanism 2 can emit microwaves to the snow to quickly melt the snow by utilizing the principle of microwave heating. Moreover, after the air is heated by the heating element of the blowing mechanism 3, the fan is used to blow hot air to the snow on the photovoltaic panel, which can further melt the snow on the surface of the photovoltaic panel, and can also sweep the unmelted snow and the snow that has melted into water to blow the snow on the surface of the photovoltaic panel away from the photovoltaic panel, thereby reducing the residual snow on the photovoltaic panel and improving the efficiency of cleaning the snow on the surface of the photovoltaic panel.

[0029] It should be noted that when the drone is used to clear the snow on the surface of the photovoltaic panel, the drone can be controlled to fly above the surface of the photovoltaic panel by any appropriate means such as manual operation control or automatic positioning of the drone. At this time, the heating mechanism 2 and the blower mechanism 3 under the fuselage 1 can work together to clear the snow on the surface of the photovoltaic panel. In addition, the microwave transmitter 210 in the heating mechanism 2 can also be designed to have adjustable irradiation intensity and irradiation range. In this way, when the thickness of snow on the surface of the photovoltaic panel is different, a more appropriate irradiation intensity and irradiation range can be selected, so that the snow on the surface of the photovoltaic panel can be cleared more intelligently. In addition, a safety protection mechanism can also be provided inside the microwave transmitter 210, such as microwave leakage detection and an emergency stop button, so that the microwave transmitter 210 can quickly cut off the microwave radiation and shut down when an abnormal working situation occurs, thereby improving the safety of the drone when removing snow through the microwave transmitter 210.

[0030] In some embodiments, reference Figures 2 to 5 As shown, the bottom of the fuselage 1 is provided with a plurality of heating zones 101, and each heating zone 101 is provided with a plurality of microwave transmitters 210. In this way, the plurality of microwave transmitters 210 can further improve the snow clearing range of the drone, and the plurality of heating zones 101 can also adaptively clear the snow through one or more heating zones 101 according to the different snow removal amounts. For example, reference can be made to Figure 3 and Figure 5 As shown, the number of heating zones 101 can be three, and the three heating zones 101 are arranged side by side at the bottom of the fuselage 1 of the drone, and each heating zone 101 is arrayed with eight microwave emitters 210. In this arrangement, the staff can adaptively open one, two or three heating zones 101 according to the thickness of snow on the surface of the photovoltaic panel, so as to clear the snow on the surface of the photovoltaic panel through different degrees of microwave emission, thereby more intelligently clearing the snow on the surface of the photovoltaic panel.

[0031] It should be noted that the number of heating zones 101 and microwave launchers 210 in each heating zone 101 mentioned in the above specific embodiment is exemplary. In an embodiment not shown in the figure, the number of heating zones 101 can be any number more than one, and the number of microwave launchers 210 in each heating zone 101 can be the same or different, and can also be any suitable number, and the present disclosure does not make any specific limitations on this.

[0032] In some embodiments, reference Figures 2 to 5As shown, the blower mechanism 3 includes a housing 310, an air duct is formed inside the housing 310, a fan and a heating element are arranged inside the housing 310 (the fan and the heating element are not shown in the figure), and an air outlet 311 connected to the air duct is arranged on the housing 310. In this way, the heating element can heat the air, and then the heated air is blown out from the air outlet 311 through the air duct through the rotation of the fan, thereby accelerating the melting of snow on the surface of the photovoltaic panel and blowing away the snow, which can improve the snow clearing efficiency of the drone for the snow on the surface of the photovoltaic panel.

[0033] In the above embodiments, the heating element may be constructed as any suitable heating element. For example, the heating element may be any suitable structure such as a heating wire, a heating rod or an infrared heating lamp tube, and the present disclosure does not make any specific limitation on this.

[0034] In some embodiments, reference Figure 2 and Figure 5 As shown, there are two shells 310 and they are arranged symmetrically relative to the heating mechanism 2, there are multiple fans and air outlets 311 and they correspond one to one, and the air outlets 311 are arranged in the shell 310 away from the first side wall 3101 connected to the fuselage 1. In this way, multiple fans and multiple air outlets 311 can be respectively provided in the two shells 310. When the snow on the surface of the photovoltaic panel is cleaned by the air blowing mechanism 3, hot air can be blown by the multiple fans in the two shells 310 at the same time, and the wind blown by the fans can be blown to the surface of the photovoltaic panel through the multiple air outlets 311 to clean the snow on the surface of the photovoltaic panel. The two shells 310 are symmetrically arranged on both sides of the heating mechanism 2. When the drone flies above the photovoltaic panel, the snow on the surface of the photovoltaic panel can be cleaned over a larger area, thereby improving the snow clearing efficiency. Further, referring to Figures 2 to 5 As shown, the air outlet 311 is set on the first side wall 3101 of the shell 310. When the drone flies above the photovoltaic panel, the first side wall 3101 can directly face the surface of the photovoltaic panel, and then the surface of the photovoltaic panel can be directly blown through multiple air outlets 311 to efficiently clear the snow on the surface of the photovoltaic panel.

[0035] It should be noted that the number of fans and air outlets 311 in a single housing 310 can be arranged in any suitable manner and position. Figure 3 and Figure 5 In the given embodiment, three fans and three air outlets 311 can be arranged side by side on a single shell 310. When blowing away the snow on the surface of the photovoltaic panel, the snow can be blown away entirely or at least partially through the air outlets 311 by the three fans. Alternatively, in an embodiment not shown in the figure, the number of fans and air outlets 311 can be any other suitable number, and the present disclosure does not make any specific limitation on this.

[0036] In some embodiments, reference Figure 3 and Figure 5 As shown, the hair dryer mechanism 3 also includes a temperature sensor 320 connected to the shell 310. The temperature sensor 320 can monitor the temperature of the hot air blown out of the air outlet 311 by the fan after the heating element is heated, so as to facilitate manual or automatic control of the heating temperature of the heating element to select a more suitable wind temperature to clear the snow on the surface of the photovoltaic panel.

[0037] In some embodiments, reference Figure 3 and Figure 5 As shown, the number of temperature sensors 320 is multiple and connected to the housing 310 at intervals. In this way, the multiple temperature sensors 320 can monitor the wind temperature at different positions, thereby facilitating the drone to select a more suitable wind temperature to clean the snow on the surface of the photovoltaic panel. In order to improve the monitoring effect of the wind temperature, for example, reference can be made to Figure 3 and Figure 5 In the given embodiment, multiple temperature sensors 320 can be arranged one-to-one on the side walls of the shell 310 adjacent to the air outlet 311. Under this arrangement, a single temperature sensor 320 can monitor the wind temperature of the nearest single air outlet 311 in real time, thereby improving the accuracy of wind temperature monitoring, and preventing thermal runaway of the heating element in the drone due to excessive wind temperature, thereby improving the safety performance of the drone during snow removal.

[0038] In some embodiments, reference Figure 3 and Figure 5 As shown, the UAV also includes a cleaning mechanism 4 connected to the bottom of the fuselage 1, and the cleaning mechanism 4 includes a driving member 410, a rod body 420 and a brush body 430. The driving member 410 is connected to the bottom of the fuselage 1; the rod body 420 is rotatably connected to the fuselage 1 and driven by the driving member 410; the brush body 430 is connected to the rod body 420, and the brush body 430 can be stored or extended from the fuselage 1 as the rod body 420 rotates. In this way, the cleaning mechanism 4 can cooperate with the heating mechanism 2 and the blower mechanism 3 to jointly clean the snow on the surface of the photovoltaic panel to reduce the residual snow on the surface of the photovoltaic panel. When the cleaning mechanism 4 cleans the snow on the surface of the photovoltaic panel, the driving member 410 can drive the rod body 420 to rotate, and then the brush body 430 can be driven to extend out of the fuselage 1. The brush body 430 directly contacts the surface of the photovoltaic panel, and the driving member 410 drives the rod body 420 to swing, or the drone moves relative to the surface of the photovoltaic panel, so as to clean the snow on the surface of the photovoltaic panel. After the snow is cleaned, the driving member 410 can also drive the rod body 420 to rotate in the opposite direction, and drive the brush body 430 and the rod body 420 to be stored in the fuselage 1 together, which can also play a role in storing the cleaning mechanism 4.

[0039] In the above specific embodiments, the driving member 410 can be constructed as any suitable structure. For example, the driving member 410 can be a power element with an output shaft such as an electric motor. The present disclosure does not make specific limitations on this. The output shaft of the driving member 410 can be directly connected to the rod body 420, thereby driving the rod body 420 to swing. For example, Figure 3 and Figure 5 In the given embodiment, the cleaning mechanism 4 as a whole can be embedded in the bottom of the fuselage 1 when the snow on the surface of the photovoltaic panel is not cleaned, the output shaft of the driving member 410 can be connected to the rod body 420, and the driving member 410 can also at least partially socket the rod body 420. When it is necessary to clean the snow on the surface of the photovoltaic panel by the brush body 430, the output shaft of the driving member 410 can drive the rod body 420 to rotate, and then extend the brush body 430 outside the fuselage 1 to clean the snow on the surface of the photovoltaic panel.

[0040] In addition, based on the above specific implementation, the brush head of the brush body 430 can be constructed as a brush head of any suitable material that does not damage the surface of the photovoltaic panel. For example, the brush head of the brush body 430 can be a silicone brush or a bristle brush, etc., and the present disclosure does not make specific limitations on this.

[0041] In some embodiments, reference Figures 1 to 6 As shown, the drone also includes a camera 5 connected to the fuselage 1. In this way, the camera 5 can perform image recognition of snow on the surface of the photovoltaic panel, and then determine the distribution and thickness of snow on the surface of the photovoltaic panel. The staff can adjust the snow removal strength of the heating mechanism 2, the blower mechanism 3 and the cleaning mechanism 4 through the image recognized by the camera, and then the snow on the surface of the photovoltaic panel can be cleaned more intelligently by the drone, which can improve the snow removal efficiency.

[0042] On the basis of the above specific implementation manner, the camera 5 can also identify other abnormal conditions on the surface of the photovoltaic panel. For example, the camera 5 can also identify damage or residual dirt on the surface of the photovoltaic panel, and can feed back this information to the user. In addition, the camera 5 can also be constructed as a high-resolution wide-angle camera. In this way, when the drone is flying, the camera 5 can capture a wider field of view, and then can more comprehensively capture the residual snow on the surface of the photovoltaic panel, so as to facilitate subsequent snow removal operations.

[0043] In some embodiments, reference Figures 1 to 6As shown, the camera 5 is located on the upper part or the side of the fuselage 1. In this way, when the camera 5 captures the images of the UAV during flight, it will not interfere with the heating mechanism 2, the blowing mechanism 3 and the cleaning mechanism 4 under the fuselage 1, thereby allowing the UAV to have higher self-safety during snow removal operations.

[0044] In some embodiments, reference Figures 1 to 6 As shown, the UAV also includes a controller 6 disposed in the fuselage, and the controller 6 is signal-connected to the heating mechanism 2, the blower mechanism 3, the cleaning mechanism 4 and the camera 5 respectively. In this connection mode, the controller 6 can serve as the core of the UAV to automatically control each mechanism on the UAV or manually control it by the user, thereby improving the intelligence of the UAV in cleaning snow on the photovoltaic panel. For example, the controller 6 can receive the image recognized by the camera 5, and then can recognize the snow area and snow thickness on the surface of the photovoltaic panel, and can transmit the recognized image back to the controller 6 in the form of a signal for analysis, and intelligently control the snow removal strength of the heating mechanism 2, the blower mechanism 3 and the cleaning mechanism 4 according to the analysis result. For example, when the controller 6 controls the heating mechanism 2, the controller 6 can intelligently control the opening and closing of multiple microwave transmitters 210 in one or more heating zones 101, so as to jointly transmit microwaves to the snow through one or more heating zones 101, and can also control the microwave transmitter 210 of the irradiation intensity; when the controller 6 controls the blower mechanism 3, the controller 6 can intelligently control the opening and closing of one or more fans, and can also control the opening and closing and heating intensity of the heating element; when the controller 6 controls the cleaning mechanism 4, it can control the opening and closing of the driving member 410, thereby driving the rod body 420 and the brush body 430 to be unfolded or stored relative to the driving member 410, and can also control the swing amplitude and frequency of the rod body 420, and then can intelligently control the brush body 430 to clean the snow on the surface of the photovoltaic panel; it should be noted that the control of each mechanism by the above-mentioned controller 6 can be carried out simultaneously or at least partially control one or several mechanisms to perform snow removal operations. The present disclosure does not make specific limitations on this. Under the above-mentioned control method, the drone can more efficiently clean the snow on the surface of the photovoltaic panel and reduce the residual snow on the surface of the photovoltaic panel.
