Description

Technical Field

[0001] This utility model relates to the field of wind power blade technology, and in particular to an auxiliary device for wind power blades. Background Technology

[0002] Wind turbine blades are the core components of wind turbines, used to convert wind energy into mechanical energy and then generate electricity. Wind turbine blades face many challenges during transportation, so an auxiliary device for wind turbine blades is used to facilitate their transportation.

[0003] To address this, patent CN222353515U discloses a wind turbine blade inspection auxiliary device, comprising a fixed base, a movable base, and a push rod. In this device, both the movable and fixed bases have uniformly spaced cavities. A connecting port is provided at the end of each cavity on opposite sides of the movable and fixed bases. A push rod slides through the connecting port, with one end inserted into the cavity and fixedly connected to a piston block. The piston block is slidably connected within the cavity, and a spring is fixedly connected to the end face of the piston block. The other end of the spring is fixedly connected to the inner wall of the cavity. Electromagnets are fixedly connected to the outer sides of the movable and fixed bases corresponding to the push rod. The push rod is made of magnetic material. The piston block compresses the spring within the cavity, causing the extension length of the push rod to change. This allows the end of the push rod to abut against the surface of the wind turbine blade. The electromagnets magnetically attract and fix the push rod, thus stably clamping the curved wind turbine blade.

[0004] Although the aforementioned wind turbine blade testing auxiliary device enables stable clamping of curved wind turbine blades via the top rod, its applicability is low because it is inconvenient to rotate and cannot change the limitations imposed on the blades by sharp turns during transportation. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary device for wind turbine blades to solve the problem of existing auxiliary devices for wind turbine blades being inconvenient to rotate.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a wind turbine blade auxiliary device, including a vehicle body;

[0007] A rotating structure is provided on one side of the top of the vehicle body. The rotating structure includes a first mounting groove opened on one side of the top of the vehicle body. A fixing seat is fixed inside the first mounting groove. A first internal cavity is provided inside the fixing seat. A rotating shaft is provided on one side of the first internal cavity. A worm gear is fixed on the outside of the rotating shaft. A worm is meshed with one side of the worm gear. A first servo motor is installed on the outer wall of the fixing seat at one end of the worm. The top of the fixing seat extends to the outside of the vehicle body and is fixed with a pressure bearing.

[0008] A fixing plate is fixed to the top of the rotating structure, and a support structure is provided on the side of the vehicle body top away from the rotating structure. An installation component is fixed to the top of the fixing plate.

[0009] An adjustment structure is provided on one side of the top of the fixed plate.

[0010] When using this device, the rotating structure enables easy rotation of the device, thereby improving its applicability in use; the adjusting structure enables easy adjustment of the device, thereby improving its ease of use; and the supporting structure enables easy support of the device, thereby improving its stability in use.

[0011] Preferably, the top end of the pressure bearing is fixedly connected to the bottom end of the fixed plate, the bottom end of the rotating shaft extends into the interior of the fixed seat and forms a rotating structure with the fixed seat, the top end of the rotating shaft extends into the exterior of the fixed seat and is fixedly connected to the bottom end of the fixed plate, and one end of the worm extends into the exterior of the fixed seat and is fixedly connected to the output end of the first servo motor. When the worm drives the worm wheel to rotate inside the first internal cavity, the worm wheel will drive the fixed plate to rotate at the top of the pressure bearing through the rotating shaft, and the fixed plate will drive the blade body to rotate, thereby reducing the turning radius and changing the limitation on the blade during sharp turns in transportation.

[0012] Preferably, the mounting assembly includes a blade body, a support base, a mounting plate, a fixing nut, and threaded posts. The support base is fixed to the top of the fixing plate, and the blade body is disposed at the top of the support base. Threaded posts are evenly distributed through one end of the blade body, and the mounting plate is fixed to one end of each threaded post. Fixing nuts are threadedly connected to the outer side of each threaded post on one side of the blade body. The support base provides support for the blade body, and the fixing nuts and threaded posts work together to fix the blade body in place.

[0013] Preferably, the adjustment structure includes an adjustment plate, a connecting seat, a first hinge seat, a connecting plate, a second hinge seat, and an electric push rod. The adjustment plate is fixed to one side of the mounting plate. Connecting seats are fixed to both sides of the bottom of the adjustment plate. A first hinge seat is fixed to one side of each connecting seat. A connecting plate is fixed to one side of the adjustment plate. A second hinge seat is fixed to the bottom of the connecting plate. An electric push rod is hinged to the bottom of the second hinge seat. When the electric push rod moves the adjustment plate through the second hinge seat and the connecting plate, the adjustment plate will cause the first hinge seat to rotate around one end of the fixed plate through the connecting seat.

[0014] Preferably, one side of the bottom of the first hinge seat is hinged to one side of the fixed plate, and the bottom end of the electric push rod is hinged to the top of the vehicle body. At this time, the adjusting plate will drive the blade body to move, thereby changing the angle of the blade body.

[0015] Preferably, the support structure includes a second mounting slot, a movable seat, a threaded rod, a hinged rod, a second internal cavity, a second servo motor, a support plate, a rubber pad, and a slide rod. The second mounting slot is located on one side of the top of the vehicle body. A threaded rod is provided on one side inside the second mounting slot. Movable seats are threaded to the outer sides of both ends of the threaded rod. Hinged rods are hinged to both sides of the top of the movable seat. The top of each hinged rod extends to the outside of the vehicle body and is hinged to a support plate. A rubber pad is fixed to the top of the support plate. A slide rod passes through one side of the inside of each movable seat. A second internal cavity is formed inside the vehicle body at one end of the threaded rod. A second servo motor is installed on one side inside the second internal cavity. Because the threads at both ends of the threaded rod are in opposite directions, the threaded rod will drive the movable seats at both ends to move in opposite directions. Under the action of the slide rod, the movable seats are prevented from rotating with the threaded rod.

[0016] Preferably, the threads at both ends of the threaded rod are in opposite directions. One end of the threaded rod extends into the interior of the second internal cavity and is fixedly connected to the output end of the second servo motor. The top end of the rubber pad abuts against the bottom end of the fixed plate. The slide rod and the movable seat form a sliding structure, and both ends of the slide rod are fixedly connected to the inner wall of the vehicle body. After moving, the movable seat drives the support plate to move up and down through the hinge rod, causing the support plate to drive the rubber pad to abut against the bottom end of the fixed plate, thereby supporting the fixed plate.

[0017] The advantages of the wind turbine blade auxiliary device provided by this utility model are as follows:

[0018] By incorporating a rotating structure, when the worm gear drives the worm wheel to rotate inside the first internal cavity, the worm wheel will drive the fixed plate to rotate at the top of the pressure bearing via the rotating shaft. Under the action of the pressure bearing, it can bear part of the weight, while reducing the friction between the fixed plate and the vehicle body. The fixed plate will drive the blade body to rotate, thereby reducing the turning radius and changing the limitation on the blade during sharp turns during transportation. This realizes the function of the device to facilitate the rotation angle, thereby improving the applicability of the wind turbine blade auxiliary device in use.

[0019] With the adjustment structure, when the electric push rod drives the adjustment plate to move through the second hinge seat and the connecting plate, the adjustment plate will drive the first hinge seat to rotate around one end of the fixed plate through the connecting seat. At this time, the adjustment plate will drive the blade body to move, thereby changing the angle of the blade body. This realizes the function of the device to easily adjust the angle, thereby improving the convenience of the wind power blade auxiliary device in use.

[0020] By incorporating a support structure, and with the threads at both ends of the threaded rod moving in opposite directions, the threaded rod drives the movable seats at both ends to move in opposite directions. Under the action of the sliding rod, the movable seats are prevented from rotating along with the threaded rod. After moving, the movable seats drive the support plate to move up and down through the hinge rod, causing the support plate to bring the rubber pad into contact with the bottom end of the fixed plate, thus supporting the fixed plate. This achieves the function of easy support for the device, thereby improving the stability of the wind turbine blade auxiliary device during use. Attached Figure Description

[0029] Reference Figure 3 and Figure 5As shown, the first servo motor 307 is started, which drives the worm gear 308 to rotate inside the first internal cavity 303. The worm gear 308 drives the worm wheel 304 to rotate. At this time, the worm wheel 304 will drive the fixed plate 2 to rotate at the top of the pressure bearing 305 through the rotating shaft 306. Under the action of the pressure bearing 305, it can bear part of the weight, while reducing the friction between the fixed plate 2 and the vehicle body 1. The fixed plate 2 will drive the blade body 401 to rotate, thereby reducing the turning radius and changing the restriction on the blade during sharp turns in the transportation process.

After moving, the moving seats 602 drive the support plate 607 to move up and down through the hinge rod 604, so that the support plate 607 drives the rubber pad 608 to abut against the bottom end of the fixed plate 2, so as to support the fixed plate 2.

[0032] A mounting assembly 4 is fixed to the top of the fixed plate 2. An adjustment structure 5 is provided on one side of the top of the fixed plate 2.
