[0001] The invention relates to the technical field of wind power generation, and in particular to a wind turbine blade cleaning drone. Background Art

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind is a pollution-free energy source. Using wind power to generate electricity is very environmentally friendly and can generate huge amounts of electricity. Therefore, more and more countries are paying more attention to wind power generation. At present, wind turbines need to be cleaned when encountering ice and snow weather. Specifically, the ice and snow attached to the surface of the motor blades in the wind turbines are cleaned to prevent the blades from being affected by too much ice and snow.

[0003] However, due to the huge size of wind turbine blades and the fact that each wind turbine has three blades, in actual use, the amount of snow-melting agent that a drone can carry each time is limited. Therefore, after the snow-melting agent is used up, the drone needs to return for replenishment and then repeat the cleaning process until the ice and snow on the blades are completely covered with snow-melting agent. The entire cleaning process requires multiple replenishments of snow-melting agent, which is inefficient. Summary of the invention

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Example 1, reference Figures 1 to 8 , which is the first embodiment of the present invention, provides a wind turbine blade cleaning drone, the device includes a main unit 100, including a drone body 101, four connecting arms 102 arranged on the drone body 101; a cleaning connecting unit 200, including a clamping component 1 201 arranged on the connecting arm 102, a clamping component 202 arranged below the drone body 101 and connected to the clamping component 1 201, a bottom supporting and limiting component 203 arranged on the clamping component 202, a spraying component 204 arranged on the drone body 101 and connected to the medicine box 202a component, and a sealing component 205 arranged on the medicine box 202a component and connected to the spraying component 204.

[0033] Among them, the four connecting arms 102 are respectively fixedly connected to the four corners of the drone body 101, and the connection and disassembly of the cleaning connection unit 200 and the main unit 100 can be realized through the clamping component 1 201 and the clamping component 2 202.

[0034] When in use, the medicine box 202a is installed and connected to the four connecting arms 102 through the clamping component 1 201 and the clamping component 202. At this time, the drone body 101 can fly and carry the medicine box 202a to spray and clean the wind turbine blades. When the medicine box 202a carried on the drone body 101 has been sprayed, the medicine box 202a can be removed as a whole through the clamping component 1 201 and the clamping component 202 to replace it with another medicine box 202a to continue the cleaning work (since the medicine box 202a is an integral whole, a sufficient amount of medicine boxes 202a can be prepared in advance for backup, and then the operation of replacing the medicine box 202a can be directly performed, which saves the process of replenishing the medicine in the medicine box 202a on site, thereby improving the cleaning efficiency of the device).

[0035] Example 2, reference Figures 1 to 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the first clamping component 201 includes a connecting ring 201a arranged on the connecting arm 102, three clamping pins 201b arranged on the connecting ring 201a, a clamping block 201c arranged on the clamping pin 201b, and a connecting spring 201d arranged on the clamping pin 201b and connected to the clamping block 201c; wherein, the connecting ring 201a is fixedly connected to the bottom of the connecting arm 102, the clamping pin 201b is slidably connected to the connecting ring 201a through a sliding hole, and the three clamping pins 201b are annularly distributed on the outer periphery of the connecting ring 201a, the clamping block 201c is fixedly connected to the clamping pin 201b, the clamping block 201c is located at the inner ring of the connecting ring 201a, and the bottom of the clamping block 201c is set as an inclined surface to cooperate with the clamping component 202 for connection or disassembly.

[0036] Furthermore, the snap-on component 202 includes a medicine box 202a arranged below the drone body 101, four connecting columns 202b arranged on the medicine box 202a, and an upper fixing block 202c arranged on the connecting column 202b; wherein, the four connecting columns 202b and the four connecting rings 201a are in a corresponding relationship up and down, and when the connecting column 202b is connected to the connecting ring 201a, it is located in the inner circle of the connecting ring 201a, the connecting column 202b is fixedly connected to the top of the medicine box 202a, the upper fixing block 202c is fixedly connected to the top of the connecting column 202b, and the top of the upper connecting column 202b is set as an inclined surface, which is convenient for cooperating with the connecting component 1 to perform connection operations.

[0037] Furthermore, the second clamping assembly 202 further includes a vertical limit groove 202b-1 provided on the connecting column 202b, and a lower sliding block 202b-2 provided outside the connecting column 202b and connected to the vertical limit groove 202b-1; wherein the vertical limit groove 202b-1 is provided on the outer surface of the connecting column 202b, the lower sliding block 202b-2 is slidably connected to the vertical limit groove 202b-1, the bottom of the lower sliding block 202b-2 is inclined, and the upper fixed block 202c is connected to the lower sliding block 20 The inclined surfaces of 2b-2 are arranged back to back, and the shapes of the upper fixed block 202c and the lower sliding block 202b-2 are exactly the same, but the directions are opposite, and a certain gap is left between the lower sliding block 202b-2 and the upper fixed block 202c, so that the lower sliding block 202b-2 can slide in the vertical limiting groove 202b-1 until it is completely fitted with the upper fixed block 202c, so that the clamping block 201c is separated from the position between the upper fixed block 202c and the lower sliding block 202b-2, thereby realizing the disassembly of the medicine box 202a.

[0038] Furthermore, the bottom support limit assembly 203 includes a recessed disposal area 203a arranged on the medicine box 202a, a pressure spring 203b arranged on the recessed disposal area 203a, and a bottom support plate 203c arranged on the pressure spring 203b and in contact with the drone body 101; wherein the recessed disposal area 203a is arranged in the middle position of the top of the medicine box 202a, the number of the pressure springs 203b is arranged in plurality, and the bottom end of the pressure spring 203b is fixedly connected to the recessed disposal area 203a, and the top end of the pressure spring 203b is fixedly connected to the top of the bottom support plate 203c, When the human-machine body 101 is connected to the medicine box 202a, the weight of the drone body 101 will automatically squeeze the connecting spring 201d on the clamping block 201c to achieve a fixed connection. When the medicine box 202a is connected to the drone body 101, the bottom of the drone body 101 fits perfectly on the supporting plate 203c.

[0039] When in use, the drone body 101 is installed downward on the medicine box 202a by aligning the positions of the connecting ring 201a and the connecting column 202b. Since the drone body 101 has a certain importance, when it is placed on the medicine box 202a in the aligned position, its own weight causes the clamping block 201c to be squeezed by the upper fixed block 202c when moving downward, until it enters the position between the upper fixed block 202c and the lower sliding block 202b-2 to complete the fixing operation; after the medicine box 202a is fixedly connected to the drone body 101, it is in a connected state with the spraying component. When the installation of the medicine box 202a is completed, the drone body 101 can be controlled to carry the medicine box 202a to spray and clean the wind turbine blades;

[0040] On the contrary, when the medicine box 202a carried on the drone body 101 has been sprayed, continue to press down the drone body 101 so that the upper fixed block 202c and the lower sliding block 202b-2 fit together. At this time, the clamping block 201c can be taken out, and the medicine box 202a can be removed as a whole and replaced with another medicine box 202a to continue the cleaning work.

[0041] The remaining structures are the same as those of Example 1.
