[0002] Wind turbine blades are the core components of wind turbines, responsible for converting natural wind energy into electrical energy. The main function of wind turbine blades is to capture wind energy and convert it into mechanical energy through rotation, and then convert it into electrical energy through generators. They are the most critical part of wind turbines, and their performance directly affects the efficiency and power generation of the entire wind turbine.
[0003] Wind turbine blades are generally very long and need to be transported with the help of a special transport flatbed truck. The transport flatbed truck provides a mounting base for the wind turbine blades. The wind turbine blades are installed on the mounting base far above the flatbed through the flange at the bottom. In this way, the entire wind turbine blade is in a cantilevered state during transportation, and the blades on the rear side are severely deformed. When the transport vehicle runs on a bumpy road, it is easy to cause damage to the wind turbine blades. For this reason, we proposed a transport fixture for maintaining the shape of wind turbine blades to solve the above problems. Utility Model Content

[0014] In the utility model, a transport clamp for maintaining the shape of a wind turbine blade is provided with a shape-stabilizing mechanism on the upper side of a carrying plate, and the entire shape-stabilizing mechanism can drive a second threaded rod to rotate and drive a slide plate to slide on the carrying plate through a second motor to change different supporting positions of the bottom of the wind turbine blade. The design here is suitable for supporting wind turbine blades of different lengths. In the shape-stabilizing mechanism, a first motor is used to drive a first threaded rod to drive the slide seats on both sides to move toward the middle synchronously, so that the arc grooves on the slide seats are close to each other, thereby clamping and stabilizing the two sides of the wind turbine blade. At the same time, a plurality of groups of springs and abutting circular plates are provided on the inner side of the arc groove to abut against the side of the wind turbine blade. The spring can adaptively shrink so that the abutting circular plate on the top can fit and abut against the side of the wind turbine blade, thereby avoiding incomplete abutment due to the arc slope on the side wall of the wind turbine blade, thereby improving practicality.

A transport fixture for maintaining the shape of a wind turbine blade comprises: a carrying plate 1, a mounting seat 2 is fixedly mounted on the carrying plate 1, a wind turbine blade 3 is arranged on the side of the mounting seat 2, a flange 31 is arranged at the bottom of the wind turbine blade 3, the wind turbine blade 3 is screwed on the mounting seat 2 through the flange 31, and a shape-stabilizing mechanism 4 is arranged at the bottom of the wind turbine blade 3.
[0021] In this embodiment, the shape-stabilizing mechanism 4 includes a slide plate 41, which is slidably arranged on the upper side of the carrying flat plate 1 and has side seats 42 screwed on both sides of the slide plate 41. A slot 43 is provided on the inner side of the side seat 42, and a roller 44 is rotatably installed on the inner side of the slot 43. A slide seat 45 is symmetrically slidably arranged on the upper side of the slide plate 41, and a first threaded rod 47 is screwed through the inner side of the slide seat 45. It should be noted that the first threaded rod 47 is a bidirectional threaded rod, and its bidirectional thread adopts a centrally symmetrical design. This is an existing conventional technical means and will not be repeated here. A first motor 48 is fixedly installed on the upper side of the slide seat 45. The output end of the first motor 48 is connected to the first threaded rod 47 by a coupling, a second threaded rod 6 is threadedly passed through the inner side of the slide plate 41, a second motor 5 is fixedly installed on the upper side of the carrying plate 1, the output end of the second motor 5 is connected to the second threaded rod 6 by a coupling, an axle seat 7 is rotatably installed on the outer end of the second threaded rod 6, the axle seat 7 is threadedly installed on the upper side of the carrying plate 1, an arc groove 49 is fixedly installed on the upper side of the slide seat 45, a bottom pad 410 is installed at the bottom of the arc groove 49, a number of abutting circular plates 412 are evenly distributed on the sides of the arc groove 49, and a spring 411 is connected between the inner wall of the arc groove 49 and the abutting circular plate 412.
[0022] Through the above-mentioned arrangement, starting the second motor 5 can drive the second threaded rod 6 to rotate and then drive the slide plate 41 to slide on the carrying flat plate 1, which can change the support clamping point of the entire shape-stabilizing mechanism 4. When the first motor 48 rotates, it drives the first threaded rod 47 to rotate. Since the first threaded rod 47 is a bidirectional thread symmetrical arrangement, the rotation of the first threaded rod 47 can drive the slide seats 45 symmetrically arranged on both sides to move closer to the middle, thereby clamping and shaping the wind turbine blades 3. At the same time, the drivable design of the slide seats 45 symmetrically arranged on both sides also makes it suitable for the clamping dimensions of wind turbine blades of different widths.
[0023] In this embodiment, the side seat 42 is L-shaped and is screwed to the slide plate 41 .
[0024] By means of the above arrangement, the side seat 42 is L-shaped and can be snapped onto the two sides of the carrying platform 1 , so that the slide plate 41 has better stability when sliding on the carrying platform 1 .
[0025] In this embodiment, three groups of notches 43 and rollers 44 are equidistantly arranged along the inner side of the side seat 42 . The rollers 44 do not contact the inner side of the notches 43 and are made of rubber.

[0027] In this embodiment, stabilizing rods 46 slide through both sides of the slide seat 45 , and the stabilizing rods 46 are fixedly mounted on the slide plate 41 .
[0028] Through the above-mentioned arrangement, the stabilizing rod 46 is arranged so that when the slide seat 45 slides driven by the first threaded rod 47 , both sides thereof can be guided by the stabilizing rod 46 for sliding movement.
[0029] The working principle of the transfer fixture for maintaining the shape of wind turbine blades provided by the utility model is as follows:
[0030] When in use, when carrying the wind turbine blade 3, the wind turbine blade 3 is first screwed and installed on the mounting seat 2 through the flange 31 at the bottom thereof, and then the position of the slide plate 41 is adjusted according to the length of the wind turbine blade 3, thereby changing the support clamping point, starting the second motor 5 to rotate, and the second motor 5 drives the second threaded rod 6 to rotate, and the second threaded rod 6 drives the slide plate 41 to slide on the carrying flat plate 1 through screw connection, and after the slide plate 41 is adjusted to a suitable position, the second motor 5 stops driving, and at this time the first motor 48 is started to rotate, and the first motor 48 drives The first threaded rod 47 rotates, and the first threaded rod 47 drives the slide seats 45 on both sides to move closer to each other through threaded connection, and then the inner sides of the arc grooves 49 on the slide seats 45 move closer to each other. When the inner sides of the arc grooves 49 on both sides form a clamping effect on the wind turbine blades 3, the first motor 48 stops rotating, and the entire shape-stabilizing mechanism 4 forms a stable clamping and supporting effect on the wind turbine blades 3, so that the wind turbine blades 3 are no longer in a purely cantilevered state, reducing the deformation of the wind turbine blades 3 during transportation, preventing the wind turbine blades 3 from being damaged due to excessive deformation, and improving practicality.
