Technical Field

[0001] The present invention relates to the technical field of wind turbine blade installation equipment, and in particular to a wind turbine blade installation device and installation method assisted by a drone. Background Art

[0002] With the development of renewable energy technology, wind turbines, as important equipment for converting wind energy into electrical energy, have attracted wide attention for their efficiency and reliability. A typical wind turbine consists of wind turbines, towers, and wind turbine blades; among them, the design of wind turbine blades has a decisive influence on the power generation efficiency of the entire unit.

[0003] The installation of wind turbines, especially wind turbine blades, is a technical challenge. The existing blade installation method usually involves installing the hub on the wind turbine, and then lifting multiple blades onto the hub in sequence by a crane. However, in this process, since it is difficult for the driver to observe the installation information at a higher position in the cockpit, a lifting blind spot is created. This results in poor lifting position accuracy, low installation efficiency, and increased safety risks during the installation process.

[0004] Based on this, in order to enable the operator to conveniently observe the installation position during the process of lifting the blades, we propose a drone-assisted wind turbine blade installation device and method. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art, such as the difficulty for the driver to observe the installation information at a higher position in the cockpit, resulting in a blind spot for lifting, and to propose a drone-assisted wind turbine blade installation device and method.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0011] A synchronization component for driving the two slide plates to slide relative to each other is also arranged above the parking platform.

[0012] Furthermore, the synchronization component includes a gear rotatably connected to the parking platform, a rack is fixedly connected to the side of the skateboard, the two racks are respectively engaged with the two sides of the gear, and a spring is fixedly connected between one end of the rack and the other skateboard.

[0013] Furthermore, the clamping block is connected to the slide plate via a fastener;

[0014] A slope is provided at the bottom of the clamping block, and the slope is clamped on the upper part of the supporting leg of the drone.

[0015] Furthermore, the lifting and rotating mechanism includes a sleeve fixed on the parking platform, an extension rod is movably inserted into the inner side of the sleeve, and the extension rod is fixed to the top plate;

[0016] The outer side of the sleeve is provided with a Z-shaped guide groove, and the outer side of the extension rod is fixedly connected with a guide shaft sliding in the Z-shaped guide groove.

[0017] Furthermore, the extension rod has a through hole inside, and an electric push rod is fixedly installed on the top of the top plate. The shaft end of the electric push rod passes through the through hole and is rotatably connected to the top of the parking platform.

[0018] Furthermore, a side edge of the rack is fixedly connected to a wedge block, and a trigger rod that abuts against the wedge block is fixedly installed on the bottom of the top plate.

[0022] Fix the crane at a predetermined position, connect the hook on the crane arm to the wind turbine blade, and lift the arm to lift the wind turbine blade to the installation location;

[0023] The top plate is raised by the lifting and rotating mechanism to release the drone;

[0024] The drone takes video of the installation location to avoid blind spots during lifting;

[0025] After the installation is completed, the drone is reset to the parking platform and the boom is reset.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-6 An embodiment of the present invention discloses a UAV-assisted wind turbine blade installation device, wherein the installation device comprises a crane 1, and the crane 1 is used to lift the blade so as to install the blade at the wind turbine generator. The specific structure of the crane 1 is prior art and will not be described in detail herein.

[0036] In addition, there is a mounting slot 11 on the upper side of the crane 1, and a parking platform 2 is fixedly installed in the mounting slot 11;

[0037] A drone 3 is placed above the parking platform 2, and a fixing mechanism 4 for fixing the drone 3 is also provided above the parking platform 2;

[0038] The top of the parking platform 2 is connected to a top plate 6 via a lifting and rotating mechanism 5 , and a pressing mechanism 7 for resisting the UAV 3 is disposed at the bottom of the top plate 6 .

[0039] In some embodiments, the fixing mechanism 4 of the present invention includes two slide plates 41 sliding on the top of the parking platform 2. In this embodiment, a T-shaped slide groove can be opened on the end surface of the parking platform 2, and the bottom of the slide plate 41 can slide in the slide groove through a T-shaped slider, and a clamping block 42 is fixedly installed on the upper side of the slide plate 41;

[0040] A synchronization component for driving the two slide plates 41 to slide relative to each other is also arranged above the parking platform 2 .

[0041] On the basis of the above embodiments, the synchronization component in this embodiment includes a gear 43 rotatably connected to the parking platform 2, a rack 44 is fixedly connected to the side of the skateboard 41, the two racks 44 are respectively engaged on both sides of the gear 43, and a spring 45 is fixedly connected between one end of the rack 44 and the other skateboard 41.

[0042] That is, in this embodiment, the design of the synchronization component is adopted to realize the synchronous clamping of the drone 3 to ensure the clamping stability of the drone 3. Specifically, when a slide plate 41 moves during clamping, its side is fixed with a rack 44. With the cooperation of the gear 43, the rack 44 on the other side also moves synchronously, so that the slide plates 41 on both sides can realize synchronous sliding movement, and then complete the center clamping and fixing of the drone 3. Secondly, in this embodiment, the spring 45 is used to reset the two slide plates 41 after clamping, so as to realize the clamping and unlocking of the drone 3.

[0043] It should be noted that in this embodiment, the clamping block 42 is connected to the slide plate 41 via a fastener;

[0044] There is an inclined surface at the bottom of the block 42, and the inclined surface is engaged with the upper part of the supporting leg of the drone 3. Specifically, in this embodiment, two blocks 42 are installed on each of the slides 41, and the inclined surfaces of the blocks 42 are in contact with the side edges of the supporting legs of the drone 3 to complete the limiting fixation of the drone 3.

[0045] On the basis of the above embodiment, the lifting and rotating mechanism 5 in this embodiment comprises a sleeve 51 fixed on the parking platform 2, an extension rod 52 is movably inserted inside the sleeve 51, and the extension rod 52 is fixed to the top plate 6;

[0046] The outer side of the sleeve 51 has a Z-shaped guide groove 53 , and the outer side of the extension rod 52 is fixedly connected to a guide shaft 54 ​​that slides in the Z-shaped guide groove 53 .

[0047] That is to say, in this embodiment, by adopting the cooperation of the Z-shaped guide groove 53 and the guide shaft 54, when the extension rod 52 moves upward, driven by the Z-shaped guide groove 53, the entire top plate 6 will rotate and move. The purpose of adopting this structural design is to ensure that the top plate 6 rotates to one side of the drone 3, so as not to interfere with the take-off of the drone 3.

[0048] Of course, in order to realize the lifting and lowering control of the top plate 6, the extension rod 52 in the present invention has a through hole inside, and an electric push rod 55 is fixedly installed on the top of the top plate 6. The axial end of the electric push rod 55 passes through the through hole and is rotatably connected to the top of the parking platform 2. When the top plate 6 needs to be lifted and lowered, the axial end of the electric push rod 55 is extended. At this time, it contacts the reverse thrust of the parking platform 2, and the top plate 6 moves upward. At the same time, due to the force driven by the Z-shaped guide groove 53, the entire top plate 6 will produce circumferential rotation, so as to realize the synchronous rotation of the top plate 6 during the rotation process.

[0049] Preferably, in order to drive the movement of the two slide plates 41 in this embodiment, a wedge block 46 is fixedly connected to the side of one of the racks 44, and a trigger rod 61 that abuts against the wedge block 46 is fixedly installed at the bottom of the top plate 6.

[0050] That is, in the present invention, a wedge block 46 is fixed on a rack 44. In the reset state, when the top plate 6 is reset downward, the trigger rod 61 at the bottom of the top plate 6 will contact the inclined surface of the wedge block 46, thereby driving the corresponding rack 44 to move. At this time, the synchronous rotation of the gear 43 is used to control the synchronous movement of the two racks 44, so that the two slides 41 can be driven synchronously, and the synchronous clamping and fixation of the drone 3 can be completed.

[0051] In a preferred embodiment, the clamping mechanism 7 in the present invention is a spring telescopic rod fixedly connected to the bottom of the top plate 6, and the spring telescopic rod is a telescopic rod section with a built-in spring. As described above, during resetting, when the top plate 6 moves downward, the bottom end of the spring telescopic rod abuts against the top of the drone 3, thereby clamping and fixing the top of the drone 3 to avoid shaking, thereby further improving the storage stability of the drone 3.

[0052] It should be noted that a mounting hole is provided on the end surface of the parking platform 2 in the present invention, and the parking platform 2 is fixed in the mounting slot 11 through the mounting hole and fasteners.

[0053] In addition, the present invention also proposes a UAV-assisted wind turbine blade installation method, which uses the above-mentioned device. Specifically, the method includes the following steps:

[0054] Fix the crane 1 at a predetermined position, connect the hook on the crane arm to the wind turbine blade, and lift the crane arm to lift the wind turbine blade to the installation location;

[0055] The top plate 6 is raised by the lifting and rotating mechanism 5 to release the drone 3;

[0056] Drone 3 takes video of the installation location to avoid blind spots during lifting;

[0057] After the installation is completed, the drone 3 is reset to the parking platform 2 and the boom is reset.

[0058] To summarize, the present invention integrates a parking platform 2 on the crane 1. When the drone 3 is placed on the parking platform 2, the installation position can be remotely viewed by releasing the drone 3 when lifting the wind turbine blades. This can avoid problems such as inaccurate lifting positions caused by lifting blind spots, greatly improving the installation and convenience of the operation. Secondly, the present invention designs a top plate 6 for shielding and protection of the drone 3. In addition, the fixing mechanism 4 and the clamping mechanism 7 can greatly improve the stability of the storage and fixation of the drone 3 to meet the stability requirements when following the crane 1.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
