Description

Technical Field

[0001] This utility model relates to the field of protection device technology, specifically a protection device for a blade marine support. Background Technology

[0002] Onshore and offshore wind turbine blades are generally over 60 meters long, with some offshore blades exceeding 100 meters. These blades are not only huge in size but also weigh tens of tons, making them difficult to transport. To solve this problem and improve transportation efficiency, ocean shipping is usually used, which has become the mainstream method for transporting such large blades.

[0003] Due to the large waves at sea, existing technology typically uses brackets to fix the blades. The upper and lower sets of protective plates on the bracket work together to quickly fix the blades. Considering the large weight of the blades, four diagonal braces are set on the bracket to effectively enhance the overall stability of the bracket. At the same time, four protruding bolt pin holes are designed at the top of the bracket, which allows workers to move the bracket with a crane and flexibly adjust the position of the bracket. Ultimately, the blades can be fixedly installed in different areas of the ship, meeting the fixing requirements in maritime transport.

[0004] However, after the blades are transported to the designated location, they need to be transferred from the ship using a crane. During the lifting operation, the upper protective plate of the support must be removed first, and then the blades are lifted. During this process, the blades are prone to shaking. If the shaking amplitude is large, it may collide with the diagonal rod of the support and the bolt pin hole, which may cause scratches on the blade surface and affect the subsequent use of the blades. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a protective device for blade marine support, which can solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A protective device for a blade marine support includes: The bracket body has a lower guard plate in the middle and an upper guard plate on top of the lower guard plate. The inner side of the bracket body has four sets of diagonal braces, and the top of the bracket body has four sets of bolt pin holes evenly distributed. The protective assembly includes a sleeve, a base plate, and replacement parts. The sleeve is fitted onto the outside of the bolt pin hole. The bottom of the sleeve is provided with a base plate. One side of the base plate is provided with an elastic band. One side of the elastic band is provided with a hook. The other side of the base plate is provided with a slot. The hook is inserted into the slot. The replaceable parts include a limiting groove, a limiting groove is provided on the inner side of the base plate, a limiting block is provided on the inner side of the limiting groove, and a flexible protective pad is provided on the top of the limiting block.

[0007] Furthermore, a bolt is threaded through the inner side of the hook, and a second threaded hole is opened on the inner side of the slot, with the bolt screwed into the inner side of the second threaded hole.

[0008] Furthermore, the limiting groove has a threaded post through the internal thread, and the limiting block has a first threaded hole through the inner side, with the threaded post screwed into the inner side of the first threaded hole.

[0009] Furthermore, the elastic band is wrapped around the outside of the diagonal bar.

[0010] Compared with the prior art, the beneficial effects of this utility model include: 1. By fitting the sleeve onto the outside of the bolt pin hole, the metal edge of the bolt pin hole can be directly isolated from the blade, preventing the blade from directly contacting the bolt pin hole during hoisting and movement. The elastic band is wrapped around the outside of the diagonal bar and fixed by the hook into the slot and bolt. This double fixing method ensures that the base plate is stably attached to the diagonal bar, thereby fixing the position of the flexible pad and allowing the flexible pad to continuously play its protective role. 2. Workers can replace the flexible pads with the corresponding specifications according to the width of the diagonal bar. The pre-positioning is achieved by inserting the limiting block into the limiting groove, and then the threaded post is screwed into the first threaded hole to complete the fixation. This allows for the quick replacement of the flexible pads, so that the flexible pads can fully wrap the outside of the diagonal bar. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] like Figure 1 - Figure 8 As shown, this utility model provides a protective device for a blade marine support, comprising: The bracket body 101 has a lower guard plate 103 in the middle, an upper guard plate 102 on the top of the lower guard plate 103, four sets of diagonal braces 104 on the inner side of the bracket body 101, and four sets of bolt pin holes 105 evenly arranged on the top of the bracket body 101. The protective component 200 includes a sleeve 201, a base plate 204, and replacement parts. The sleeve 201 is fitted onto the outside of the bolt pin hole 105. The bottom of the sleeve 201 is provided with a base plate 204. Multiple sets of elastic bands 203 are provided on one side of the base plate 204. A hook 205 is provided on one side of the elastic band 203. A slot 206 is provided on the other side of the base plate 204. The hook 205 is inserted into the inside of the slot 206. The replacement component includes a limiting groove 210. A limiting groove 210 is provided on the inner side of the base plate 204. A limiting block 209 is provided on the inner side of the limiting groove 210. A flexible protective pad 202 is provided on the top of the limiting block 209.

[0016] In the above scheme: 1. By cooperating with the flexible pad 202 and the sleeve 201, the bolt pin hole 105 and the outer side of the inclined rod 104 can be covered, thereby effectively protecting the blade when hoisting it. 2. Through the elastic force of the elastic band 203, and the cooperation of the hook 205 and the slot 206, the base plate 204 can be tightly fitted with the diagonal bar 104, thereby fixing the position of the flexible pad 202.

[0017] In this embodiment, a bolt 207 is threaded through the inner side of the hook 205, and a second threaded hole 212 is opened on the inner side of the slot 206, and the bolt 207 is screwed into the inner side of the second threaded hole 212.

[0018] In the above solution: the threaded connection between the bolt 207 and the second threaded hole 212 can effectively restrict the movement of the hook 205 in the slot 206. Even if the bracket is subjected to bumps and vibrations during sea transport, it can ensure that the hook 205 will not fall out of the slot 206, thereby ensuring the stable connection between the base plate 204 and the inclined rod 104 and continuously providing protection for the blade.

[0019] In this embodiment, the limiting groove 210 is provided with a threaded post 208 through the thread, and the limiting block 209 is provided with a first threaded hole 211 through the thread, and the threaded post 208 is screwed into the inside of the first threaded hole 211.

[0020] In the above scheme: At this time, the worker holds the knob of the threaded column 208 and rotates the threaded column 208 clockwise. The threaded column 208 is gradually screwed into the first threaded hole 211. The limiting block 209 is firmly fixed in the limiting groove 210 and cannot move laterally or longitudinally. This can avoid the diagonal rod 104 directly contacting the blade and causing scratches due to the displacement of the flexible pad 202.

[0021] In this embodiment, the elastic band 203 is wrapped around the outside of the diagonal bar 104.

[0022] In the above scheme: During the installation process, after the worker attaches the base plate 204 to the outside of the diagonal bar 104, he pulls the elastic band 203 so that it wraps around the circumference of the diagonal bar 104. At this time, the elastic band 203 is in a stretched state, and the elastic force generated can press the base plate 204 tightly onto the surface of the diagonal bar 104.

[0023] In this embodiment, to prevent the blade from touching the bolt pin hole 105 and the diagonal bar 104 during hoisting and causing scratches, the operator first needs to replace the flexible pad 202 with one of the corresponding specifications according to the width of the diagonal bar 104. The flexible pad 202 is pre-positioned by inserting the limiting block 209 into the limiting groove 210, at which point the threaded post 208 and the first threaded hole 211 are aligned. The operator then rotates the threaded post 208 to screw it into the first threaded hole 211, thus fixing the position of the flexible pad 202. This facilitates effective protection of the blade by the flexible pad 202. Finally, the sleeve 201 is fitted over the bolt pin hole 105. On the side, the bolt pin hole 105 is protected. Then, the worker pulls the elastic band 203 and controls the hook 205 to engage with the inside of the slot 206, so that the base plate 204 and the outer side of the inclined rod 104 can be brought into contact. The elasticity of the elastic band 203 can make the base plate 204 and the outer side of the inclined rod 104 fit tightly. Then, the worker screws the bolt 207 into the inside of the second threaded hole 212, so as to fix the position of the base plate 204. This allows the flexible pad 202 to cover the outer side of the inclined rod 104, so that when the blade is hoisted out from the inside of the lower guard plate 103, the inclined rod 104 and the bolt pin hole 105 can be prevented from scratching the blade.
