Description

Technical Field

[0001] This utility model belongs to the field of offshore wind turbine rotor cooling duct manufacturing technology, specifically relating to an adjustable pipe diameter protection device for offshore wind turbines. Background Technology

[0002] Currently, the components of cooling ducts for offshore wind turbine rotors involve thin-plate straight pipes, elbows, and other parts. A significant issue during the storage and transportation of these thin-plate ducts is pipe diameter protection. Since most duct components are made of thin stainless steel plates, typically around 0.7mm thick, with diameters ranging from 500-600mm and lengths from 200-2000mm, the stainless steel material, thin plates, and relatively long duct lengths cause the ends to ovate to varying degrees due to their own weight. This negatively impacts the duct's shape during storage and transportation. Traditional fixed-diameter protection devices are no longer sufficient and may detach from the pipe, failing to protect the diameter. Therefore, it is necessary to use adjustable pipe diameter protection devices to protect the duct diameter. Thus, we need a new type of adjustable pipe diameter protection device for offshore wind turbines to solve the above problems and meet the required needs. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable pipe diameter protection device for offshore wind power, so as to solve the problems of easy detachment from the pipe and inability to protect the pipe diameter.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable pipeline diameter protection device for offshore wind power, comprising...

[0005] A straight pipe needs to be protected. The top of the straight pipe has an open circular flange. Inside the open circular flange is a hexagonal double-ended bolt, and outside the hexagonal double-ended bolt is a standard M8 nut. Preferably, the hexagonal double-ended bolt is an M8x35 hexagonal double-ended bolt with opposite threads at both ends.

[0006] Preferably, the open circular flange is made by rolling an L-shaped folded edge piece.

[0007] Preferably, the outer diameter of the open circular flange is equal to the inner diameter of the straight pipe to be protected.

[0008] Preferably, the hexagonal double-ended bolt is connected to the standard fastener M8 nut via thread.

[0009] Preferably, hexagonal double-ended bolts and standard fastener M8 nuts are connected by electric welding to both ends of the inner side of the open circular flange.

[0010] The technical effects and advantages of this utility model are as follows: Through the implementation and research and development of this adjustable pipe diameter protection device for offshore wind power, it can effectively protect the product pipe, reduce processing precision, improve efficiency, reduce costs, and accelerate the product manufacturing cycle. It can also be effectively adjusted according to different pipe diameters, effectively provide pre-tightening force, and protect the product pipe diameter. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides, for example Figures 1-3 The illustrated offshore wind power adjustable pipeline diameter protection device includes:

[0017] The straight pipe 1 needs to be protected. The top of the straight pipe 1 is equipped with an open circular flange 4. The inside of the open circular flange 4 is equipped with a hexagonal double-ended bolt 2. The outside of the hexagonal double-ended bolt 2 is equipped with a standard fastener M8 nut 3.

[0018] Specifically, the hexagonal double-ended bolt 2 is an M8x35 hexagonal double-ended bolt with opposite threads at both ends.

[0019] Specifically, the open circular flange 4 is made by bending it into an L-shaped flange and then rolling it. Furthermore, in its natural state, the outer diameter of the open circular flange 4 is equal to the inner diameter of the straight pipe 1 to be protected.

[0020] Specifically, the outer diameter of the open circular flange 4 is equal to the inner diameter of the straight pipe 1 that needs to be protected.

[0021] Specifically, the hexagonal double-ended bolt 2 is connected to the standard fastener M8 nut 3 by thread.

[0022] Specifically, the hexagonal double-ended bolt 2 and the standard fastener M8 nut 3 are connected to both ends of the inner side of the open circular flange 4 by electric welding.

[0023] Working Principle: This adjustable pipe diameter protection device for offshore wind power utilizes a reversible threaded connection. Made of 1mm galvanized steel sheet, it is bent and rolled into an open circular flange 4. Bolts are then welded into the inside of the flange 4. The outer diameter of the flange 4 is adjusted by rotating the reversible hexagonal double-ended bolts 2, thus widening the inner diameter of the duct and protecting the duct diameter. This adjustable pipe diameter protection device protects the diameter of the straight pipe 1 that needs protection. The hexagonal double-ended bolts 2 are threaded onto standard M8 nuts 3 (the nut's position on the bolt is pre-set for easy adjustment of the outer diameter of the open circular flange 4). The hexagonal double-ended bolts 2 and standard M8 nuts 3 are then electric welded to appropriate positions on both ends of the inner side of the open circular flange 4.

[0024] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
