[0022] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. Based on the embodiments in the implementation modes, it is intended to explain the present application and should not be construed as a limitation to the present application.

[0023] As used in this specification, the phrase "in one embodiment" or "example" or "instance" means that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment disclosed in the present application. The appearances of the phrase "in one embodiment" in various positions in the specification do not necessarily refer to the same embodiment.

[0024] To solve the problems in the prior art that the pressure change in the pipeline for delivering fuel from the oil storage tank to the engine is large and difficult to accurately control. In order to ensure that the pressure in the fuel delivery pipeline between the oil storage tank and the engine is within a certain range, and to facilitate fuel delivery and recovery, a related art proposes an oil storage tank structure, which includes an independently provided fuel tank 1 and a daily-use oil tank 2. The fuel tank 1 is used to store the total fuel required during long voyages, and the daily-use oil tank 2 is used to store the fuel required for voyages within a relatively short period (daily). The fuel tank 1 delivers fuel to the daily-use oil tank 2 at regular intervals, and then the daily-use oil tank 2 continuously delivers the fuel to the engine to drive the engine. However, the separately and independently provided fuel tank 1 and daily-use oil tank 2 have problems such as low space utilization rate, large occupied space, and inconvenient fuel delivery from the fuel tank 1 to the daily-use oil tank 2.

[0025] In view of this, this embodiment proposes an oil storage tank, as Figure 1 、 Figure 2 and Figure 4 shown. An oil storage tank includes a fuel tank 1 and a daily-use oil tank 2 that are separated from each other. The fuel tank 1 and the daily-use oil tank 2 are provided as an integral structure. The daily-use oil tank 2 is located below the fuel tank 1. A fuel delivery pipeline 3 is provided between the fuel tank 1 and the daily-use oil tank 2. The fuel delivery pipeline 3 connects the fuel tank 1 and the daily-use oil tank 2. A fuel delivery pump 31 is provided on the fuel delivery pipeline 3. The delivery displacement of the fuel delivery pump 31 is usually set to 3 - 4 m 3 / h, and the outlet pressure is 0.3 - 0.5 MPa. In this embodiment, the delivery displacement of the fuel delivery pump 31 is set to 3.3 m 3 / h, and the outlet pressure is 0.33 MPa.

[0026] By setting the fuel tank 1 and the daily-use oil tank 2 as an integral structure, the problems of low space utilization rate and large occupied space of the split-structured fuel tank 1 and daily-use oil tank 2 in the prior art are solved, achieving the effects of improving space utilization rate and reducing space occupation; by arranging the daily-use oil tank 2 below the fuel tank 1, the problem of large pressure change and difficult precise control in the fuel pipeline from the oil storage tank to the engine is solved, reducing the pressure in the fuel delivery pipeline 3 from the daily-use oil tank 2 to the engine, and narrowing the pressure change amount in the fuel output pipeline, making the pressure in the fuel output pipeline of the daily-use oil tank 2 easy to control.

[0027] As an implementation manner, as Figure 1 , Figure 2 shown, the daily-use oil tank 2 is embedded below the fuel tank 1, and the outer side wall of the daily-use oil tank 2 is flush with the outer side wall of the fuel tank 1.

[0028] Another implementation manner, as Figure 3 shown, the fuel tank 1 and the daily-use oil tank 2 form a double-layer structure, the daily-use oil tank 2 is located in the lower layer, and the fuel tank 1 is located in the upper layer.

[0029] The above two implementation manners are further limitations on the relative position relationship between the fuel tank 1 and the daily-use oil tank 2. By setting the fuel tank 1 and the daily-use oil tank 2 in the above two connection relationships, the fuel delivery between the fuel tank 1 and the daily-use oil tank 2 can be made more convenient while achieving the beneficial effects of this application. It should be noted that the above two specific connection manners of the fuel tank 1 and the daily-use oil tank 2 in this embodiment do not limit the connection relationship between the fuel tank 1 and the daily-use oil tank 2.

[0030] As an implementation manner, the fuel delivery pipeline 3 is arranged outside the fuel tank 1 and the daily-use oil tank 2. Arranging the fuel delivery pipeline 3 outside the fuel tank 1 and the daily-use oil tank 2 can facilitate the installation and maintenance of the fuel delivery pipeline 3. Specifically, the fuel delivery pipeline 3 is arranged outside the outer side walls on the left and right sides of the fuel tank 1 and the daily-use oil tank 2 and is fixed by a pipe rack. The layout of the fuel pipeline should also follow the principle of being far away from heat surfaces, electrical devices or other ignition sources, and should be enclosed or other appropriate protective measures should be taken to prevent fuel spraying or leakage onto the ignition source.

[0031] In addition, this embodiment also proposes a setting manner of the fuel delivery pipeline 3 and the fuel delivery pump 31 (not shown in the figure). A hollow chamber is formed between the fuel tank 1 and the daily-use oil tank 2, and the fuel delivery pipeline 3 and the fuel delivery pump 31 are arranged in the hollow chamber. Arranging the fuel delivery pipeline 3 and the fuel delivery pump 31 in the hollow chamber between the fuel tank 1 and the daily-use oil tank 2 further improves the space utilization rate and makes the distribution of each component in the oil storage tank more compact.

[0032] As a way to achieve this, Figure 4 As shown, the side walls of the fuel tank 1 and the daily fuel tank 2 are respectively provided with magnetic float level gauges 4 for indicating the fuel liquid level. The magnetic float level gauge 4 is also called a magnetic floating level gauge, which is a measuring instrument that uses a magnetic float as a sensing element and reflects the measured liquid level or interface through the coupling effect between the magnetic float and the magnetic body in the display color bar. The liquid level of the fuel in the fuel tank 1 and the daily fuel tank 2 can be easily read through the magnetic float level gauge 4.

[0033] As a way to achieve this, Figure 4 As shown, the side wall of the daily oil tank 2 is provided with an oil inlet 21 connected to the fuel delivery pipeline 3, an oil outlet 22 for delivering fuel to the outside, and an oil return port 23 for recovering external fuel. The fuel tank 1 inputs fuel into the oil inlet 21 of the daily oil tank 2 through the fuel delivery pipeline 3, and the daily oil tank 2 delivers fuel to the generator set 7 and the internal combustion engine in the ship's power compartment through the oil outlet 22 and the fuel delivery pipeline 3 connected to the oil outlet 22. The oil return port 23 is used for the daily oil tank 2 to recover the remaining fuel in the generator set 7 and the internal combustion engine 8, which plays a role in relieving fuel pressure and reducing fuel consumption.

[0034] As an implementation method, the oil return port 23 is connected with an oil return pipe 5, which is led from the top of the daily oil tank 2 to below the lowest liquid level of the daily oil tank 2, so as to ensure that the fuel is injected from the bottom of the daily oil tank 2 after recovery.

[0035] As an implementation method, the fuel tank 1 is provided with a fuel filling port 11, and the fuel filling port 11 is connected to a fuel filling pipe 6, and the fuel filling pipe 6 penetrates into the fuel tank 1 and is led to the bottom of the fuel tank 1. The fuel filling port 11 is used to inject fuel into the fuel tank 1. The fuel filling pipe 6 is usually connected to the deck of the ship, and fuel is injected into the fuel tank 1 through the fuel filling port on the deck. The fuel filling pipe 6 is penetrated into the fuel tank 1 and led to the bottom of the fuel tank 1 to ensure that the fuel is injected from the bottom of the fuel tank 1.

[0036] Specifically, Figure 4 As shown, the fuel delivery pipeline 3 is also provided with a manual quick-closing valve, a stop check valve, a ball valve, etc. for controlling the pipeline connection or cutoff. A double fuel filter is also provided on the fuel delivery pipelines of the daily oil tank 2 and the generator set 7 and the internal combustion engine set 8.

[0037] In addition, this embodiment also provides a ship, comprising the oil storage tank described in any one of the technical solutions in the above embodiments. The reasoning process of the beneficial effects of the ship provided by this embodiment and the above oil storage tank is similar, and will not be repeated here.

[0038] In summary, in this embodiment, by integrating the fuel tank 1 and the daily-use oil tank 2, the problems of low space utilization rate and large occupied space of the fuel tank 1 and the daily-use oil tank 2 in the split structure in the prior art are solved, and the technical effects of improving the space utilization rate and reducing the space occupation are achieved; by arranging the daily-use oil tank 2 below the fuel tank 1, the problem of large pressure change and difficult precise control in the fuel pipeline from the oil storage tank to the engine is solved, the pressure in the fuel delivery pipeline 3 from the daily-use oil tank 2 to the engine is reduced, and the pressure change amount in the fuel output pipeline is reduced, making the pressure in the fuel output pipeline of the daily-use oil tank 2 easy to control.

[0039] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Those skilled in the art should understand that the present application includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present application will be included in the scope of the claims.
