Description

Technical Field

[0001] This utility model relates to the technical field of ship fuel refueling equipment, and in particular to a protective device for methanol refueling operations. Background Technology

[0002] According to regulations and practical application requirements, support equipment for refueling hoses is required to prevent hose bending and damage, and to avoid affecting the refueling rate. The conventional approach is to purchase a dedicated hose saddle to support the refueling hose. However, this dedicated equipment is relatively expensive. During refueling operations, the protective chain needs to be removed from the saddle area to set up the saddle for hose refueling. During non-refueling operations, the saddle needs to be removed and the protective chain needs to be installed to meet regulatory requirements and prevent personnel from falling from height. This repeated operation increases the workload of the crew and poses operational risks. Existing technology has the following drawbacks: (1) Dedicated saddles are expensive; (2) Single function: the saddle and protective chain need to be disassembled and reassembled alternately, which takes a long time; (3) Poor adaptability: the fixed curvature cannot be adapted to DN150 / DN200 dual pipe diameters.

[0003] Therefore, this utility model proposes a protective device for methanol medium filling operations, which solves the problems of high cost and cumbersome operation of traditional special saddles. Summary of the Invention

The modular adjustable structure solves the problems of high cost and cumbersome operation of traditional special saddles.

[0005] The purpose of this utility model is achieved as follows:

[0006] A protective device for methanol refueling operations includes a main support structure and modular protective components. The main support structure includes a support steel pipe and a support column. The modular protective components include a replaceable arc plate, quick-release connectors, and a wear-resistant pad.

[0007] The supporting steel pipe is horizontally welded to the side of the ship, and the top of the supporting column is welded to the end of the supporting steel pipe. The replaceable arc plate is connected to the supporting steel pipe by a quick-release connector. The quick-release connector adopts a spring pin. A wear-resistant pad is provided between the supporting steel pipe and the replaceable arc plate. The wear-resistant pad is bonded to the inner wall of the replaceable arc plate. An anti-slip guard is provided at each end of the replaceable arc plate.

[0008] Furthermore, the radius of the supporting steel pipe is not less than 150mm, and the length of the supporting steel pipe is 3000mm.

[0009] Furthermore, the top of the support column is beveled at 30° and welded to the end of the support steel pipe.

[0010] Furthermore, the bottom flange of the support column is fixed to the deck.

[0011] Furthermore, the inner radius of the replaceable arc plate is greater than 150mm.

[0012] Furthermore, the wear-resistant pad layer uses a polytetrafluoroethylene gasket with a thickness of 3mm.

[0013] Furthermore, the anti-slip guard is 50mm high to prevent the hose from slipping.

[0014] Furthermore, D-shaped rings are welded to the sides of the support column, and protective chains are installed when not in operation.

Example 1

[0025] See Figure 1-2 , Figure 1 A schematic diagram of a protective device for methanol refueling operations according to Embodiment 1 is shown. As shown in the figure, the protective device for methanol refueling operations according to Embodiment 1 includes a main support structure and modular protective components. The main support structure includes a support steel pipe 1 and a support column 2. The modular protective components include a replaceable arc plate 3, a quick-release connector 4, and a wear-resistant pad 5.

[0026] The supporting steel pipe 1 is horizontally welded to the side of the ship. The radius of the supporting steel pipe 1 is not less than 150mm, which meets the bending radius of the DN200 hose. The length of the supporting steel pipe 1 is 3000mm.

[0027] The top of the support column 2 is cut at a 30° angle and welded to the end of the support steel pipe 1, and the bottom flange of the support column 2 is fixed to the deck.

[0028] The replaceable arc plate 3 is connected to the supporting steel pipe 1 via quick-release connector 4. The replaceable arc plate 3 is available in two specifications: DN150 and DN200, with an inner arc radius R=180mm (>minimum bending radius 150mm).

[0029] The quick-release connector 4 uses a spring pin, which can complete the replacement of the arc plate in 10 seconds;

[0030] A wear-resistant pad 5 is provided between the supporting steel pipe 1 and the replaceable arc plate 3. The wear-resistant pad 5 is made of 3mm thick polytetrafluoroethylene gasket and is bonded to the inner wall of the replaceable arc plate 3 with a friction coefficient of <0.1.

[0031] The replaceable arc plate 3 has an anti-slip guard 6 at each end, the anti-slip guard 6 being 50mm high to prevent the hose from slipping.

[0032] The support column 2 has a D-shaped ring welded to its side, and a protective chain is installed when not in operation.

[0033] Working principle:

[0034] This utility model provides a protective device for methanol medium refueling operations, including the following installation and working process;

[0035] (1) Installation process:

[0036] 1. Secure the support column to the deck via flanges, and weld the support steel pipe at the top at an angle.

[0037] 2. Select an arc plate that matches the hose specification and press the spring pin to insert it into the steel pipe;

[0038] 3. When not refueling, the protective chain is attached to the D-ring.

[0039] (2) Workflow:

[0040] 1. Filling operation: The hose is placed inside the arc plate, and the PTFE padding reduces friction;

[0041] 2. Protection switching: After the operation is completed, remove the hose and hook the protective chain back to form a closed railing.

[0042] This utility model achieves a breakthrough solution through an innovative combination of "permanent fixing of steel pipe support columns" and "quick-change arc plate":

[0043] (1) Functional integration: A single structure simultaneously meets the needs of hose support (during operation) and personnel protection (during non-operation);

[0044] (2) Cost optimization: Using general-purpose steel to replace the special saddle reduces material costs by 80%;

[0045] (3) Convenient maintenance: The PTFE pad has a lifespan of up to 5 years and the quick-release design allows for tool-free replacement.

[0046] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
