[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0028] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The technical solution of the present utility model is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
[0029] like Figure 2 and Figure 4As shown, the methanol fuel tank provided by the present invention includes two methanol tanks 3, which are symmetrically arranged inside the top tank 4 of the hull 2. The top tank 4 is located in the cargo hold 202. Figure 3 As shown, distributed in the upper left corner or upper right corner of the cargo hold 202, the topside tank 4 is a space area surrounded by the deck 201, the side outer plate 211, the cargo hold longitudinal wall plate 212, the front cabin plate 213, and the rear cabin plate 214.
[0030] When storing methanol, the methanol is stored in the two methanol tanks 3 as evenly as possible to maintain the balance of the hull 2 and improve the balance and stability of the ship. Figure 3 As shown, a ballast tank 5 may also be provided at the bottom of the cargo hold 202 .
[0031] Compared with setting the methanol tank 3 on the deck 201 or in the cargo hold 202, the adoption of this technical solution occupies less effective space of the ship and has less impact on the spatial structure distribution of the ship, thereby improving the economy of the ship.
[0032] In a feasible solution, the cross section of the methanol tank 3 is a right triangle.
[0033] like Figure 3 and Figure 4 As shown, the cross section of the methanol tank 3 is approximately a right triangle. The reason why it is set to a right triangle is to reduce the impact on the cargo hold 202, specifically on the cargo hold longitudinal wall plate 212.
[0034] In one possible solution, Figure 4 As shown, the methanol tank 3 of the methanol fuel tank has a specific structure including: a first vertical side panel 204, a top panel 205, a second vertical side panel 206, a bottom panel 207, a longitudinal wall panel 208, a rear end panel 210 and a front end panel 209.
[0035] Among them, the first vertical side plate 204 and the second vertical side plate 206 are arranged vertically, the top plate 205 and the bottom plate 207 are arranged horizontally, and the longitudinal wall plate 208 is arranged inclined.
[0036] In order to reduce the impact on other structures of the hull 2, the above vertical and horizontal settings are approximate.
[0037] The two ends of the top plate 205 are respectively arranged on the top of the first vertical side plate 204 and the second vertical side plate 206 ( Figure 4 The distal end of the bottom plate 207 ( Figure 4 The left end is fixed to the bottom end of the second vertical side plate 206 ( Figure 4 The two ends of the longitudinal wall plate 208 are respectively connected to the bottom end of the first vertical side plate 204 ( Figure 4The lower end) and the proximal end of the bottom plate 207 ( Figure 4 The first vertical side plate 204, the top plate 205, the second vertical side plate 206, the bottom plate 207, and the longitudinal wall plate 208 together form a cylindrical space.
[0038] The front and rear ends of the cylindrical space ( Figure 2 The first vertical side plate 204, the top plate 205, the second vertical side plate 206, the bottom plate 207, the longitudinal wall plate 208, the rear end plate 210 and the front end plate 209 together form a closed space, i.e., the methanol tank 3.
[0039] In a feasible solution, it also includes: a supporting structure.
[0040] The methanol tank 3 is located inside the top tank 4, and there is an isolation tank 203 between the methanol tank 3 and the top tank 4. The methanol tank 3 and the supporting structure are arranged in the space between the top tank 4 and the methanol tank 3, and are used to support the methanol tank 3.
[0041] The supporting structure can be in various shapes, such as plate-shaped, column-shaped, etc., which is the prior art, and its function is to provide support between the methanol tank 3 and the top tank 4 and the side outer plate 211. The supporting structure should be as simple as possible and easy to weld to reduce the amount of welding.
[0042] In a feasible solution, the distance between the topside tank 4 and the methanol tank 3 ranges from 900 mm to 1500 mm. Figure 4 As shown, the width or thickness of the isolation cabin 203 is Figure 4 The distance range marked by w in the figure is 900 mm to 1500 mm. Specifically, w can be 900 mm, 1000 mm, 1200 mm, 1500 mm, or any value between 900 mm and 1500 mm. Figure 4 The range of middle w is set to 900mm to 1500mm, the purpose of which is to provide welding space and good supporting force.
[0043] In a feasible solution, the width of the bottom plate 207 is 900 mm to 1500 mm.
[0044] Right now Figure 4 The length of D is in the range of 900 mm to 1500 mm. D can be 900 mm, 1000 mm, 1200 mm, 1500 mm, or any value between 900 mm and 1500 mm.
[0045] This technical solution is adopted to reduce the welding workload and also to reduce stress concentration.
[0046] In a feasible solution, the width of the first vertical side plate 204 is 600 mm to 1500 mm.
[0047] Right now Figure 4 The length of H in the middle ranges from 600 mm to 1500 mm. Wherein, D can be 600 mm, 700 mm, 800 mm, 900 mm, 1000 mm, 1200 mm, 1500 mm, or any value between 600 mm and 1500 mm.
[0048] This technical solution is adopted to reduce the welding workload and also to reduce stress concentration.
[0049] In a feasible solution, the interior of the methanol tank 3 is divided into a plurality of small compartments.
[0050] Dividing the interior of the methanol tank 3 into a plurality of small compartments can reduce the influence of methanol swaying during transportation on the stability of the hull 2 .
[0051] In a feasible solution, adjacent small compartments are connected to each other.
[0052] For example, by providing conducting holes between the small compartments, methanol can flow in the methanol compartment 3 as necessary, thus achieving dynamic adjustment and avoiding violent shaking, thereby maintaining the stability of the hull.
[0053] In a feasible solution, adjacent small compartments are connected via solenoid valves.
[0054] Solenoid valves are set between adjacent small compartments, and the conduction state of the solenoid valves can be adjusted through the control system to allow methanol to flow between the small compartments as necessary. On the one hand, this facilitates the loading and unloading of methanol, and on the other hand, it is to reduce the impact of violent shaking of methanol on the balance of the hull.
[0055] The methanol fuel tank of the utility model adopts the above technical solution, and the beneficial effect achieved is: it avoids the disadvantages of arranging the methanol tank on the deck or in the cargo hold on the ship space utilization, and can also effectively improve the space utilization and ship economy, while improving the balance and stability of the ship during transportation.
