Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation deicing, in particular to a blade deicing device for wind power generation. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine generally consists of components such as a wind wheel, a generator, a direction regulator, a tower, a speed limit safety mechanism, and an energy storage device.

[0003] According to Chinese patent publication number CN212318228U, a wind turbine blade de-icing device is disclosed, comprising a tower, a nacelle fixedly mounted on the top of the tower, a rotating shaft fixedly mounted on the right end of the nacelle, a blade fixedly mounted on the right end of the rotating shaft, a groove formed within the rotating shaft, located to the left of the blade, a motor fixedly mounted on the left side wall of the groove, and a transmission shaft fixedly mounted on the output end of the motor, which passes through the middle of the blade. This wind turbine blade de-icing device has the advantage of high de-icing efficiency, solving the problem of ice forming on the blade surface of wind turbines on rainy days in cold seasons, which reduces the efficiency of the generator and increases the load on the blades and the unit. When the amount of ice is large, it may even require the unit to be shut down to ensure the safety of the blades and the nacelle. Existing wind turbine blades are mostly de-iced manually when ice forms, which not only has low de-icing efficiency but also wastes a lot of manpower and material resources.

[0004] In cold climates, wind turbine blades are prone to ice formation, which not only reduces power generation efficiency but may also damage the blades and even affect the safe operation of the entire wind power generation system. Traditional de-icing methods usually include manual de-icing, hot air de-icing, and mechanical de-icing, but these methods have many limitations:

[0005] Manual de-icing requires workers to climb to high places to perform the operation, which is labor-intensive and poses safety hazards; using hot air to de-icer consumes a lot of energy, increasing operating costs; mechanical de-icing may cause scratches or damage to the blade surface, affecting the service life of the blade. Utility Model Content

[0006] The purpose of the utility model is to provide a wind turbine blade deicing device, which can avoid the traditional deicing methods such as manual deicing, hot air deicing and mechanical deicing, which have many limitations.

[0007] The utility model provides a wind power generation blade de-icing device, including a drone, wherein a mounting long plate is provided on the support legs of the drone, a hollow rod is rotatably provided on the mounting long plate, one end of the hollow rod is fixedly connected to a first de-icing assembly, a rotating rod passes through the mounting long plate, the hollow rod and the first de-icing assembly and is fixedly connected to a second de-icing assembly, the rotating rod is rotatably connected to the mounting long plate, the hollow rod and the first de-icing assembly, and the first de-icing assembly and the second de-icing assembly have the same structure.

[0008] Preferably, the first deicing assembly is located on the lower side of the second deicing assembly.

[0009] Preferably, the first deicing assembly includes a transverse plate, which is fixedly connected to the hollow rod. An elastic buckle strip is provided on one side of the transverse plate, a water pipe is clamped in the elastic buckle strip, and a plurality of nozzles are installed on the water pipe.

[0010] Preferably, the nozzle is in an inclined state.

[0011] Preferably, symmetrical insertion holes are respectively provided at both ends of the transverse plate, and positioning buckles are inserted into the insertion holes.

[0012] Preferably, the outer side of one end of the hollow rod is connected to gear 1, and the rear side of the long plate is rotatably provided with gear 2, and gear 1 and gear 2 are meshed.

[0013] Preferably, one end of the rotating rod extending out of the hollow rod is connected to gear three, and a gear four is provided on the rear side of the long plate for rotation, and gear four is engaged with gear three.

[0014] Preferably, a bracket is provided on the lower side of the drone, and a camera is installed in the bracket via a rotating shaft.

[0015] Preferably, one end of the camera shaft is connected to a knob with teeth on its surface, and the teeth of the knob engage with the teeth on the inner side of the limiting sleeve.

[0016] Preferably, symmetrical snap-in grooves are provided on the side walls of the bracket, and snap rings are symmetrically provided on one side of the limiting sleeve, and the snap rings are snap-fitted with the snap-in grooves.

[0017] The present invention provides a wind turbine blade deicing device that, compared with the prior art, has the following advantages:

[0018] 1. The utility model uses a drone carrying a first de-icing component and a second de-icing component to spray de-icing agent on the blades of a wind turbine to de-ice. At the same time, a rotating rod is used to drive the first de-icing component to rotate, and a hollow rod drives the second de-icing component to rotate, so that the first de-icing component and the second de-icing component are crossed. The cross-spraying method can flexibly adjust the spraying area according to the shape and size of different blades to ensure that each part can be effectively treated. Moreover, when the first de-icing component and the second de-icing component are continuously rotating, the de-icing agent can be sprayed faster. The high-speed rotation increases the frequency and speed of spraying, improves the de-icing efficiency, and can also reduce the uneven spraying caused by the influence of wind, ensuring that the de-icing agent can be evenly distributed on the surface of the blade.

[0019] 2. The utility model installs a camera on the bottom of the drone to shoot the deicing process. The camera can help the operator control the flight path and spraying position of the drone more accurately, ensuring that every area that needs deicing can be effectively treated.

DETAILED DESCRIPTION

[0031] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0032] Please refer to Figures 1-8 An embodiment of the utility model provides a wind power blade de-icing device, including a drone 1, a mounting long plate 2 is provided on the support legs of the drone 1, a hollow rod 6 is rotatably provided on the mounting long plate 2, one end of the hollow rod 6 is fixedly connected to a first de-icing component 3, and the first de-icing component 3 can be connected to an external pump to pump the de-icing agent into the first de-icing component 3.

[0033] In addition, the rotating rod 5 is passed through the mounting long plate 2, the hollow rod 6, and the first de-icing assembly 3 and the second de-icing assembly 4, and the rotating rod 5 is rotatably connected to the mounting long plate 2, the hollow rod 6 and the first de-icing assembly 3. When the rotating rod 5 rotates, the second de-icing assembly 4 rotates, and when the hollow rod 6 rotates, the first de-icing assembly 3 rotates, so that the first de-icing assembly 3 and the second de-icing assembly 4 cross (such as Figure 2 As shown in the figure), the cross-spraying method can flexibly adjust the spraying area according to the shape and size of different blades to ensure that each part can be effectively treated. When the first de-icing component 3 and the second de-icing component 4 are rotating continuously, the de-icing agent can be sprayed faster. The high-speed rotation increases the frequency and speed of spraying, improves the de-icing efficiency, and at the same time, the high-speed rotation can also reduce the uneven spraying caused by the influence of wind, ensuring that the de-icing agent can be evenly distributed on the surface of the blade.

[0034] In order to prevent the first de-icing assembly 3 and the second de-icing assembly 4 from affecting each other during rotation, the first de-icing assembly 3 is located at the lower side of the second de-icing assembly 4, and there is a certain distance between the two, thereby ensuring the normal rotation of the first de-icing assembly 3 and the second de-icing assembly 4.

[0035] Among them, the first de-icing component 3 and the second de-icing component 4 have the same structure. The first de-icing component 3 includes a horizontal plate 31, which is fixedly connected to the hollow rod 6. The rotating rod 5 passes through the mounting long plate 2, the hollow rod 6 and the horizontal plate 31 of the first de-icing component 3, and is connected to the horizontal plate 31 of the second de-icing component 4. The hollow rod 6 and the rotating rod 5 can both rotate independently.

[0036] An elastic buckle strip 32 is provided on one side of the horizontal plate 31. A notch is opened on one side of the elastic buckle strip 32. A water pipe 33 is clamped in the elastic buckle strip 32. A plurality of nozzles 34 are installed on the water pipe 33. The nozzles 34 are in an inclined state. The length of the water pipe 33 can meet the flying height of the drone 1. The bottom of the water pipe 33 is connected to the de-icing agent storage device placed on the ground, and the de-icing agent is transported into the water pipe 33 by a pump, so that the nozzles 34 spray the de-icing agent on the blades.

[0037] In addition, symmetrical insertion holes 35 are respectively provided at both ends of the transverse plate 31 , and positioning buckles 36 are inserted into the insertion holes 35 . The positioning buckles 36 are used to fix the water pipe 33 so that the water pipe 33 is stably located in the elastic buckle strip 32 .

[0038] Secondly, in order to make the hollow rod 6 and the rotating rod 5 rotate independently, a gear 1 7 is connected to the outside of one end of the hollow rod 6, and a gear 2 8 is provided on the rear side of the long board 2 for rotation. The gear 2 8 is driven by a motor, and the hollow rod 6 is rotated by engaging the gear 1 7 and the gear 2 8.

[0039] Furthermore, a gear three 9 is connected to one end of the hollow rod 6 extending from the rotating rod 5, and a gear four 10 is provided on the rear side of the long board 2 for rotation. The gear four 10 is driven to rotate by the motor, and the gear four 10 is engaged with the gear three 9 to rotate the rotating rod 5.

[0040] like Figure 7 and Figure 8 As shown, a bracket 11 is provided on the lower side of the UAV 1, and a camera 12 is installed in the bracket 11 through a rotating shaft. The camera 12 is used to shoot the deicing process in real time. The camera 12 can help the operator to more accurately control the flight path and spraying position of the UAV 1 to ensure that each area requiring deicing can be effectively treated.

[0041] It is worth noting that a knob 13 with teeth on the surface is connected to one end of the camera 12 shaft, and the teeth of the knob 13 engage with the teeth on the inner side of the limiting sleeve 15. At the same time, symmetrical slots 14 are opened on the side wall of the bracket 11, and a snap ring 16 is symmetrically provided on one side of the limiting sleeve 15. The snap ring 16 is engaged with the slot 14. By rotating the shaft, the shooting position of the camera 12 can be adjusted to avoid shooting blind spots. After the camera 12 is rotated, the limiting sleeve 15 can be placed on the knob 13, and the snap ring 16 can be engaged in the slot 14 to prevent the knob 13 from rotating at will.

[0042] In summary, the working principle of a wind power blade de-icing device according to an embodiment of the present invention is as follows: a drone 1 carries a first de-icing component 3 and a second de-icing component 4 to fly to the blade, and the de-icing agent in the de-icing agent storage device is sucked into the first de-icing component 3 and the second de-icing component 4 through a pump on the ground, and the de-icing agent is sprayed on the blade. At the same time, the first de-icing component 3 is driven to rotate by the rotating rod 5, and the second de-icing component 4 is rotated by the hollow rod 6, so that the first de-icing component 3 and the second de-icing component 4 are crossed. The cross-spraying method can flexibly adjust the spraying area according to the shape and size of different blades, and the de-icing agent can be sprayed faster when the first de-icing component 3 and the second de-icing component 4 are continuously rotating. During de-icing, the camera 12 is used to shoot the de-icing process to help the operator more accurately control the flight path and spraying position of the drone 1.

[0043] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
