Description

Technical Field

[0001] This invention relates to the field of guidance and limiting technology, specifically a guidance and limiting device for the installation of a ship's airfoil sail. Background Technology

[0002] In April 2018, the Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO) adopted the "IMO Preliminary Strategy for Greenhouse Gas Emission Reduction from Ships." This preliminary strategy made overall arrangements for the international shipping industry's actions to address climate change, promoting the international shipping industry to reduce emissions as soon as possible and achieve zero greenhouse gas emissions within this century. This is the first time that the global shipping industry has set greenhouse gas emission reduction targets to address climate change. The development and application of new fuels and new energy technologies have become the most concerning topics for ship owners and the entire maritime industry.

[0003] Airfoil sails have a long history as a power source for ships, and the industry has accumulated a wealth of experience. Early real-world applications have proven their effectiveness in reducing fuel consumption, greenhouse gas emissions, and exhaust emissions. An airfoil sail is an advanced marine propulsion device that employs a rigid structure similar to an aircraft wing. Through precise design and a flexible control system, it effectively captures and utilizes wind energy to propel the vessel forward. By applying large rigid airfoil sails to large ships, fuel consumption and greenhouse gas emissions can be reduced by 15%-20%.

[0004] However, large rigid airfoil sails are difficult to install due to their large structure (height over 45m), high weight (usually no less than 200 tons), and large span of lifting points (up to 43m). They require two floating cranes to lift them together, and have high requirements for the stability of the installation base and the assembly clearance. The floating state of the ship and the influence of weather and waves, as well as the small gap between the two lugs of the sail base, make it difficult to control the movement of the sail and easily cause damage to the base lugs, sail lugs and their upper flanges. The installation process is extremely complicated, and the positional accuracy of each component is difficult to control during installation, which seriously limits the application of large rigid airfoil sails in large ships. Utility Model Content

[0005] This utility model provides a guide and limiting device for the installation of ship airfoil sails to solve the technical defects of the prior art.

[0006] To solve the above-mentioned technical problems, the present invention provides a guiding and limiting device for the installation of a ship's airfoil sail, comprising a guide bracket and a limiting guide rail. The guide bracket is disposed on the inner side of the outer ear plate of the sail mounting base, and the limiting guide rail is disposed on the sail ear plate. There are two guide brackets, respectively disposed at both ends of the inner side of the outer ear plate of the sail mounting base, and fixedly connected to the inner side of the outer ear plate perpendicular to the base surface. There are two limiting guide rails, respectively fixed on the sail ear plates on both sides of the outer arc surface of the sail flange, and extending downward in a vertical direction. The outer distance between the two limiting guide rails is smaller than the inner distance between the two guide brackets.

[0007] Specifically, the upper ends of the two guide brackets extend outward at an angle, and the angled extensions are connected to the rounded corners of the guide brackets.

[0008] Specifically, a pad is provided between the two limiting guide rails and the sail flange.

[0009] Specifically, the two limiting guide rails are located on the side away from the sail ear plate, perpendicular to the limiting guide rails, and have guide plates extending towards the two guide brackets.

[0010] Specifically, the outer side of the outer ear plate is provided with a reinforcing plate.

[0011] Specifically, the guide support ball is made of ball flat steel, and the limiting guide rail is made of angle steel.

[0012] Specifically, the guide bracket and the limiting guide rail are both fixed by welding.

[0013] Specifically, the inner surface of the guide bracket and the outer surface of the limiting guide rail are coated with lubricating oil.

[0014] Due to the design of the guide bracket and limiting rail, this utility model restricts the movement of the sail during hoisting. It transforms the small-sized base ear plate and the flange on the sail ear plate into a larger-sized guide bracket and limiting rail, effectively improving the installation speed and protecting the base ear plate, sail ear plate and its flange from damage. Furthermore, it has a simple structure, is firmly and reliably installed, safe and convenient, and highly practical. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application.

[0021] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by a person of ordinary skill in the art to which this application pertains.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a guiding and limiting device for the installation of a ship's airfoil sail, comprising a guide bracket and a limiting guide rail. The guide bracket is disposed on the inner side of the outer ear plate of the sail mounting base, and the limiting guide rail is disposed on the sail ear plate. There are two guide brackets, respectively disposed at both ends of the inner side of the outer ear plate of the sail mounting base, and fixedly connected to the inner side of the outer ear plate perpendicular to the base surface. There are two limiting guide rails, respectively fixed on the sail ear plates on both sides of the outer arc surface of the sail flange, and extending downward in the vertical direction. The outer distance between the two limiting guide rails is smaller than the inner distance between the two guide brackets. In use, cut steel of appropriate height to make guide brackets and limiting guide rails. The front guide bracket 2 and rear guide bracket 3 are directly welded to both ends of the inner side of the outer ear plate of the sail mounting base, perpendicular to the base surface and fixedly connected to the inner side of the outer ear plate. The two guide brackets are symmetrical on the left and right sides of the base ear plate 1. The front limiting guide rail 5 and rear limiting guide rail 6 are welded to the fixed rotation shaft on both sides of the sail ear plate 4, extending vertically downwards from the outer arc surface of the sail flange. They are symmetrical on the left and right, with a slightly smaller distance between the outer sides of the two limiting guide rails. The spacing between the inner sides of the two guide supports is designed so that when the floating crane is hoisting the sail, as the sail approaches the base on the ship's deck, the larger guide supports and limiting rails can be successfully matched first. That is, the two limiting rails are inserted into the two guide supports. Under the constraint of the guide supports and limiting rails, the smaller base ear plate 1 and the flange on the sail ear plate 4 are then matched, so that the connecting hole on the outer base ear plate 1 is aligned with the flange connecting hole on the inner sail ear plate 4. Finally, it is fixed with a pin, and the installation of the sail is successfully completed.

[0023] Specifically, the upper ends of the two guide brackets extend outward at an angle, and the angled extensions are connected to the guide brackets at rounded corners. The extensions are for better alignment when the guide brackets and the limiting guide rails are aligned, and the rounded corners are to reduce friction and enhance stability when inserted after alignment.

[0024] Specifically, a pad is provided between the two limiting guide rails and the sail flange, which can adjust the distance between the outer sides of the two limiting guide rails.

[0025] Specifically, the two limiting guide rails are perpendicular to each other on the side away from the sail ear plate, and a guide plate extends towards the two guide brackets to prevent the guide brackets and limiting guide rails from falling off when they are aligned.

[0026] Specifically, the outer side of the outer ear plate is provided with a reinforcing plate, which can enhance the support strength of the ear plate.

[0027] Specifically, the guide bracket ball is made of ball flat steel, and the limiting guide rail is made of angle steel, so that the guide bracket and the limiting guide rail can be better aligned when they are aligned.

[0028] Specifically, the fixing method is welding, and the welded joint has high strength, which can improve the connection quality.

[0029] Specifically, the inner surface of the guide bracket and the outer surface of the limiting guide rail are coated with lubricating oil to reduce friction and enhance stability when the guide bracket and the limiting guide rail are inserted after alignment.

[0030] The above description is merely an exemplary embodiment of this application and is not intended to limit the scope of protection of this application. The scope of protection of this application is determined by the appended claims.
