Description

Technical Field

[0001] This invention belongs to the technical field of methanol fuel tanks, and relates to a methanol fuel tank; specifically, it relates to an adjustable support methanol fuel tank equipped with a sliding lifting bearing mechanism. Background Technology

[0002] Methanol fuel, whose main component is methanol, is widely recognized as a highly promising clean alternative energy source in the shipping industry. It is colorless, flammable, easily soluble in water, and convenient to store and transport. It has a high oxygen content and burns completely, producing no sulfur oxides and low nitrogen oxides after combustion. Its carbon emissions are reduced by about 20% compared to traditional fuel oil. Moreover, it has diverse sources of production. Green methanol can achieve carbon neutrality throughout its entire life cycle and is one of the core choices for decarbonization in the shipping industry. Many ocean-going container ships use methanol dual-fuel engines as their power core, that is, replacing traditional fossil energy sources such as heavy oil and diesel with methanol fuel.

[0003] The methanol fuel tank for dual-fuel large container ships adopts a double-layer structure. The inner tank is made of corrosion-resistant stainless steel, and the outer tank is a carbon steel protective layer. The interlayer is made of spirally laid glass fiber and aluminum foil for thermal insulation. It is equipped with fixed shock absorption devices and auxiliary accessories such as liquid level, pressure, and leakage detection to ensure storage safety and stable fuel delivery. Its advantages of lightweight and easy adaptation are significant, and it can replace traditional heavy oil storage tanks. However, existing methanol fuel tanks have a small contact area between the upper fixing frame and the hull, resulting in insufficient stability. Therefore, when the tank is swayed by wind and waves during the ship's movement, although springs and other components can provide some shock absorption, they can also increase the swaying amplitude of the tank, making it prone to tipping over. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to provide an adjustable support methanol fuel tank with a sliding lifting bearing mechanism that can solve the problem of insufficient stability caused by the small contact area between the upper fixed frame and the hull in existing methanol fuel tanks.

[0005] The technical solution of the present invention is: an adjustable support methanol fuel tank equipped with a sliding lifting bearing mechanism, comprising a cylindrical tank body, and two bearing mechanisms sleeved at both ends of the outer wall of the tank body; The bearing mechanism includes a first bearing seat, on which longitudinal grooves are provided on both outer walls of the first bearing seat, and a matching support is movably installed in each of the two grooves.

[0006] Furthermore, the support includes a support block, a slider that is movably engaged in a groove is fixed to the inner wall of the support block, a second threaded rod is rotatably connected to the top of the support block via a bearing, and a fixing plate is threaded onto the outer side of the second threaded rod.

[0007] Furthermore, the support block is in the shape of a right-angled trapezoid, and the slider is in the shape of a T-shape.

[0008] Furthermore, a groove is provided inside the lower side of the first bearing seat, and a first horizontal plate is slidably connected inside the groove. A first threaded rod is threaded through the center of the first horizontal plate.

[0009] Furthermore, a second transverse plate is fitted over the outside of the first threaded rod, and the first threaded rod and the second transverse plate are rotatably connected by a bearing.

[0010] Furthermore, the top end of the first threaded rod is rotatably connected to the inner wall of the groove via a bearing.

[0011] Furthermore, two guide rods are inserted through both sides of the first support seat, and the bottom end of the guide rods is movably inserted through the first support seat and then fixed to the top of the first horizontal plate.

[0012] Furthermore, a second bearing seat is fixed to the top of each of the two guide rods.

[0013] Furthermore, two hanging rings are fixed to the top of the second support.

[0014] Furthermore, both the first and second bearing seats are fastened to the tank body.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The support of the present invention can provide stable support points on both sides of the tank by increasing the contact area between the support and the hull, thereby increasing the stability of the tank during use and preventing problems such as the tank tipping over. Moreover, by installing a hanging ring on the top of the second bearing seat, the tank can be easily lifted and moved. Attached Figure Description

Detailed Implementation

[0017] The specific technical solution of the present invention will be further described in detail below with reference to specific examples.

[0018] As shown in the figure, the adjustable support methanol fuel with a sliding lifting bearing mechanism according to the present invention includes a tank body 1. Two bearing mechanisms 2 are sleeved on the outside of the tank body 1. Each bearing mechanism 2 includes a first bearing seat 21, guide rods 22 and a second bearing seat 23. Two guide rods 22 pass through the top edge of the first bearing seat 21. The second bearing seat 23 is fixedly connected to the top of the two guide rods 22. Supports 24 are installed on both sides of the first bearing seat 21. Two hanging rings 25 are fixedly connected to the top of the second bearing seat 23. A groove 26 is formed inside the bottom side of the first bearing seat 21. A first horizontal plate 27 is slidably connected inside the groove 26. A first threaded rod 28 is threaded through the inside of the first horizontal plate 27. A second horizontal plate 29 is sleeved on the outside of the first threaded rod 28.

[0019] Tank 1 is a dedicated sealed tank for methanol fuel storage, constructed entirely of pressure-resistant and corrosion-resistant materials to meet the safety requirements for long-term storage, transportation, and use of methanol fuel. Two supporting mechanisms 2 provide all-around envelopment, clamping, and support to the tank from the outside, effectively improving the overall stability of the tank during placement, fixation, and use. The lifting ring 25 is an integrated lifting structure, allowing workers to easily lift, transport, install, and relocate the entire fuel tank and supporting mechanisms using lifting equipment, significantly improving the convenience of equipment handling and assembly.

[0020] The second horizontal plate 29 is fixed inside the groove 26. The first threaded rod 28 and the second horizontal plate 29 are rotatably connected by bearings, which can both limit the vertical movement of the first threaded rod 28 and ensure its smooth rotation. At the same time, the top end of the first threaded rod 28 is rotatably connected to the top inner wall of the groove 26 by bearings, further improving the stability of the rotation process of the first threaded rod 28 and avoiding deviation or jamming.

[0021] The bottom end of the guide rod 22 is fixed to the top of the first horizontal plate 27. The guide rod 22 is slidably connected inside the first support seat 21. The slidable guide rod 22 facilitates the up-and-down movement of the second support seat 23, thereby facilitating the clamping of the tank 1. Both the first support seat 21 and the second support seat 23 are arc-shaped fastening structures that match the curvature of the outer wall of the tank 1, allowing them to fit tightly against the outer wall of the tank 1 and ensuring a secure clamping fit.

[0022] The top end of the first threaded rod 28 is rotatably connected to the inner wall of the groove 26 via a bearing. Both the first bearing seat 21 and the second bearing seat 23 are fastened to the tank body 1. By rotating the first threaded rod 28 by holding its bottom end, the first horizontal plate 27 slides downwards along the inner wall of the groove 26 under the action of threaded transmission. Simultaneously, it drives the guide rod 22 to slide downwards along the inside of the first bearing seat 21, thereby causing the second bearing seat 23 to move downwards as a whole. Combined with the bottom-fixed first bearing seat 21, the first bearing seat 21 and the second bearing seat 23 can clamp and fix the outer wall of the tank body 1, adapting to the clamping and fixing needs of methanol fuel tanks with different outer diameters. It is highly adjustable and has a wide range of applications. Reverse rotation of the first threaded rod 28 will cause the second bearing seat 23 to move upwards, releasing the clamp on the tank body 1, facilitating the disassembly, inspection, and replacement of the tank.

[0023] The support 24 includes a second threaded rod 241, a fixing plate 242, a support block 243, and a slider 244. The fixing plate 242 is threaded onto the outer side of the second threaded rod 241, and vertical extension and retraction adjustment is achieved by means of threaded engagement. The bottom end of the second threaded rod 241 is rotatably connected to the support block 243 through a bearing. The slider 244 is fixedly connected to the inner wall of the support block 243. The support 24 can provide stable support points on both sides of the tank 1, increasing the stability of the tank 1 during use and preventing problems such as the tank 1 tipping over.

[0024] The fixing plate 242 is fixed to the first bearing seat 21. The slider 244 has a T-shaped structure and is slidably connected inside the groove 211. The support block 243 is a right trapezoid shape. The right trapezoid shape of the support block 243 increases the contact area between the support block and the hull and the mounting base, reduces the pressure per unit area, and prevents the tank from shaking or shifting when placed, making the tank 1 more stable when placed.

[0025] Working principle: When using this device, the first support seat 21 is installed on the ship. Then, the second threaded rod 241 is rotated clockwise, which will drive the support block 243 to move down continuously until the bottom of the support block 243 abuts against the ship. Then, the tank 1 is hoisted between the first support seat 21 and the second support seat 23, so that the tank 1 is located on the first support seat 21. Then, the first threaded rod 28 is rotated clockwise, which will drive the first horizontal plate 27 to move down continuously, which will drive the guide rod 22 and the second support seat 23 to move down. When the second support seat 23 moves to the top of the tank 1, it can be clamped. The user places the hook on the external crane on the hanging ring 25, which makes it easy to hoist and move the tank 1.
