Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine blade transportation, in particular to a wind turbine blade fixing bracket. Background Art

[0002] Wind power generation refers to the conversion of wind's kinetic energy 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. Before wind power generation, the wind turbine blades need to be transported to the location of the generator and then assembled by staff.

[0003] When installing the existing wind turbine blade fixing bracket, the wind turbine blade is usually placed on the transport rack, and then the wind turbine blade is fixed to the transport rack by rope tying, which makes the fixing of the wind turbine blade more complicated and reduces the work efficiency; and the existing fixing bracket cannot completely restrict the wind turbine blade, which makes it extremely easy for the wind turbine blade to fall off during transportation, which is easy to cause safety accidents. Summary of the invention

[0004] In order to solve the problem that the existing method of fixing wind turbine blades on a transport rack is rather cumbersome and the existing fixing bracket cannot completely restrain the wind turbine blades, the utility model proposes a wind turbine blade fixing bracket, which completely restrains the wind turbine blades within a certain space through the cooperation of a fixing mechanism on the mounting seat and a first baffle and a second baffle on the base, thereby improving the fixing efficiency of the wind turbine blades and reducing the probability of safety accidents.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] A wind turbine blade fixing bracket comprises a base, a plurality of mounting seats are slidably connected to the base, each of the mounting seats is provided with a groove adapted to the shape of the wind turbine blade, and each mounting seat is provided with a fixing mechanism, the fixing mechanism comprises a fixing roller, a winding roller, a binding belt and a power component for driving the winding roller to rotate, one end of the binding belt is fixed to the outer side surface of the fixing roller, and the other end is fixed to the outer side surface of the winding roller, the fixing roller and the winding roller are respectively located on both sides of the groove, a first baffle is fixed to one end of the base, and a second baffle is hinged to the other end, a first fixing seat is fixed to the base, and a second fixing seat cooperating with the first fixing seat is fixed to the second baffle, and a fixing rod is passed through the first fixing seat and the second fixing seat to realize the second baffle stopping the end of the wind turbine blade. Before the wind turbine blade is installed, the second baffle is on the same horizontal line with the base plate, which makes it convenient to place the wind turbine blade on multiple mounting seats; one end of the wind turbine blade abuts against the first baffle, and the binding strap contacts the outer side of the wind turbine blade, and then when the second baffle hinged to the base rotates to a vertical state with the base, the through holes in the first fixing seat and the second fixing seat are in a coaxial state, and a fixing rod is inserted therethrough to keep the second baffle in a vertical state, and the other end of the wind turbine blade abuts against the second baffle.

[0007] Furthermore, a slide rail with a T-shaped longitudinal section is fixed on the base, and a through groove matching the shape of the slide rail is provided on the mounting seat to realize the sliding connection between the base and the mounting seat. There are two slide rails to ensure the sliding stability of the mounting seat.

[0008] Furthermore, an extension is fixed on both sides of the mounting seat, a screw is threadedly connected to the extension, and the screw passes through the extension to contact the upper side of the base. When the screw passes through the extension to contact the upper side of the base, the mounting seat cannot slide on the base, and when the screw leaves the upper side of the base, the mounting seat can slide on the base.

[0009] Furthermore, two opposite fixed frames are provided on the mounting seat, and the two fixed frames are respectively located on both sides of the groove, one of the fixed frames is rotatably connected to the fixed roller, and the other fixed frame is rotatably connected to the winding roller, and the upper sides of the fixed frames are opened with openings, and the binding straps pass through the openings.

[0011] Furthermore, the first baffle is in contact with one end of the wind turbine blade, and the second baffle is in contact with the other end of the wind turbine blade.

[0012] Furthermore, the fixing rod is a latch or a bolt.

[0013] Through the above technical scheme, the beneficial effects of the utility model are as follows: the utility model is provided with multiple mounting seats on the base, and grooves are opened on the mounting seats for supporting wind turbine blades. The fixing structure on each mounting seat is driven by the power component, and the straps therein fix the upper side of the wind turbine blade, and then the first baffle at one end of the base abuts against the end of the wind turbine blade, and the second baffle at the other end abuts against the other end of the wind turbine blade after rotation, so that the wind turbine blade is completely confined within a certain space, which not only meets the requirement of rapid fixation of the wind turbine blade, but also reduces the probability of safety accidents.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0021] like Figure 1 to Figure 5 As shown, this embodiment provides a wind turbine blade fixing bracket, comprising a base 1, on which a plurality of mounting seats 2 are slidably connected;

[0022] Specifically, two opposite slide rails 13 with a "T"-shaped longitudinal section are fixed on the base 1, and a through groove matching the shape of the slide rails 13 is provided on the mounting seat 2 to realize the sliding connection between the base 1 and the mounting seat 2. Extensions 14 are fixed on both sides of the mounting seat 2, and screws 15 are threadedly connected to the extensions 14. The screws 15 pass through the extensions 14 and contact the upper side of the base 1. In this embodiment, when the screws 15 pass through the extensions 14 and contact the upper side of the base 1, the mounting seat 2 cannot slide on the base 1. When the screws 15 leave the upper side of the base 1, the mounting seat 2 can slide on the base 1.

[0023] Each of the mounting seats 2 is provided with a groove 4 that matches the shape of the wind turbine blade 3, and each of the mounting seats 2 is provided with a fixing mechanism;

[0024] Specifically, the fixing mechanism includes a fixing roller 5, a winding roller 6, a binding belt 7 and a power assembly for driving the winding roller 6 to rotate, one end of the binding belt 7 is fixed to the outer side surface of the fixing roller 5, and the other end is fixed to the outer side surface of the winding roller 6, and the fixing roller 5 and the winding roller 6 are respectively located on both sides of the groove 4;

[0025] In this embodiment, if Figure 1 and Figure 5 As shown, the mounting seat 2 is provided with two opposite fixing frames 16, which are respectively located on both sides of the groove 4, one of which is rotatably connected to the fixing roller 5, and the other is rotatably connected to the winding roller 6. The upper sides of the fixing frames 16 are provided with through openings, through which the binding band 7 passes; the power assembly is a servo motor 17, which is fixed in the fixing frame 16, and the output end of the servo motor 17 is connected to the winding roller 6. The tightening and loosening of the binding band 7 is controlled by the servo motor 17, and the upper side of the wind turbine blade 3 is fixed with manual cooperation.

[0026] The base 1 has a first baffle 8 fixed at one end and a second baffle 9 hinged at the other end. The base 1 has a first fixing seat 10 fixed thereon, and the second baffle 9 has a second fixing seat 11 matched with the first fixing seat 10 fixed thereon. A fixing rod 12 is inserted through the first fixing seat 10 and the second fixing seat 11 to stop the end of the wind turbine blade 3 by the second baffle 9. In this embodiment, the fixing rod 12 is a latch or a bolt, and two first fixing seats 10 and two second fixing seats 11 are provided. At the same time, in order to match the installation of the two, the first fixing seat 10 and the second fixing seat 11 are staggered.

[0027] In this embodiment, the first baffle 8 contacts one end of the wind turbine blade 3, and the second baffle 9 contacts the other end of the wind turbine blade 3. The wind turbine blade 3 is completely confined in a certain space, which reduces the possibility that the wind turbine blade 3 will be separated from the fixed bracket due to inertia when braking or accelerating during transportation.

[0028] Reference Figure 2 When in use, the hoisted wind turbine blade 3 is manually put into the groove 4 of the plurality of mounting seats 2 from one side of the hinged second baffle plate 9 of the base 1. During this process, the binding belt 7 is manually lifted to prevent the binding belt 7 from being pressed on the lower side of the wind turbine blade 3, which makes it unable to fix the wind turbine blade 3;

[0029] Then, the end of the wind turbine blade 3 first contacts the outer side of the first baffle 8, and then the servo motor 17 drives the winding roller 6 to tighten the binding belt 7 on the outer side of the wind turbine blade 3 to fix the upper and lower positions of the wind turbine blade 3. At this time, the second baffle 9 is manually pulled to make the second baffle 9 in a vertical state. At this time, the through holes in the first fixing seat 10 and the second fixing seat 11 on the base 1 are in a coaxial state. The fixing rod 12 is inserted into the first fixing seat 10 and the second fixing seat 11 to keep the second baffle 9 in a vertical state, and the other end of the wind turbine blade 3 abuts against the second baffle 9 (such as Figure 1 ) is enough.

[0030] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
