To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a fuel tank provided in the related art. As shown in fig. 1, the fuel tank includes: the heating device comprises a box body 1 and a heating device, wherein the heating device comprises a heating pipe 31 and a water injection pump 32, and the heating pipe 31 is wound on the shell of the box body 1. When the ship sails in the alpine sea area to freeze the box body 1, hot water is injected into the heating pipe 31 through the water injection pump 32, so that the ice layer near the heating pipe 31 absorbs heat and melts, and the aim of deicing is fulfilled.

However, ocean vessels are long in sailing in alpine sea areas, and therefore, the water injection pump 32 needs to be frequently started to inject hot water into the heating pipe 31 to melt ice. And a large amount of hot water is used in the ice melting process, so that the supply of the hot water is also problematic.

On one hand, the oil tank capable of removing ice provided by the related art needs to be additionally provided with a heating device, so that the manufacturing cost of the oil tank can be increased; on the other hand, a large amount of hot water is needed in the process of heating for deicing, so that the hot water needs to be continuously provided, and the deicing cost is undoubtedly increased. In addition, in the mode of heating for melting ice, the ice layer can be melted after a period of time, and the aim of deicing cannot be quickly achieved.

Therefore, the embodiment of the disclosure provides an oil tank. Fig. 2 is a schematic view of a first use state of a fuel tank provided by the embodiment of the disclosure. As shown in fig. 2, the fuel tank includes: a case 1 and an expansion mechanism.

As shown in fig. 2, the expansion mechanism is located on the outer wall surface of the case 1, and includes an expansion member 21 and a power member 22, and the power member 22 is connected to the expansion member 21.

The power member 22 is used for controlling the expansion member 21 to switch to the first state or the second state. Fig. 3 is a schematic view of a second use state of the oil tank provided by the embodiment of the disclosure. As shown in fig. 2 and 3, the volume of the expansion member 21 is larger when the expansion member 21 is in the first state than when the expansion member 21 is in the second state.

The oil tank provided by the embodiment of the disclosure comprises a tank body 1 and an expansion mechanism, wherein the expansion mechanism is arranged on the outer wall surface of the tank body 1, the expansion mechanism comprises an expansion piece 21 and a power piece 22, the power piece 22 can control the expansion piece 21 to be switched between a first state and a second state, and when the expansion piece 21 is in the first state, the volume of the expansion piece 21 is larger than that when the expansion piece 21 is in the second state. Therefore, when the ship sails in a severe cold sea area and the shell of the oil tank is frozen, the power member 22 can be controlled to switch the expansion member 21 from the second state to the first state, so that the volume of the expansion member 21 is increased, that is, the expansion member 21 rapidly protrudes from the shell of the oil tank, and the expansion member 21 impacts the accumulated snow or the ice layer on the expansion member 21, so that the accumulated snow or the ice layer is broken and falls off, and the purpose of rapidly removing ice is achieved.

Meanwhile, the expansion piece 21 can be repeatedly switched between the first state and the second state through the power piece 22, so that the accumulated snow or the ice layer on the expansion piece 21 can be repeatedly impacted by the expansion piece 21, the accumulated snow or the ice layer on the expansion piece 21 can be broken and dropped, and the deicing effect is ensured. Compared with the ice melting mode adopting a heating device, the ice melting device does not need to be additionally arranged, so that the ice removing cost can be greatly reduced, and the ice melting device is convenient to use.

In the embodiment of the present disclosure, the box body 1 may be made of a stainless steel plate, so that even if the hull of the box body 1 is frozen due to the ship sailing in the alpine sea area, the box body 1 is not prone to rusting, and the reliability of the box body 1 is improved.

Illustratively, as shown in fig. 2 and 3, the case 1 may have a rectangular parallelepiped structure. That is, the case 1 has 6 sides.

Wherein, except the side connected with the ship deck, the other 5 sides of the box body 1 can be provided with expansion mechanisms. Therefore, no matter any side surface of the box body 1 is frozen, the expansion piece 21 and the power piece 22 in the expansion mechanism can break the ice layer on the box body 1, so as to achieve the aim of deicing.

The expansion means may, for example, be arranged on the tank 1 on four sides perpendicular to the deck of the vessel. That is, the expansion mechanisms are provided on four side surfaces of the case 1 parallel to the vertical direction.

Alternatively, as shown in fig. 3, the expansion member 21 has a filling cavity 210, the expansion member 21 is provided with an injection pipe 211 communicated with the filling cavity 210, at least a partial region on the outer wall surface of the expansion member 21 is a flexible region 212, the power member 22 is communicated with the injection pipe 211, and the power member 22 is used for injecting the fluid medium into the filling cavity 210 through the injection pipe 211 or extracting the fluid medium in the filling cavity 210.

Wherein the filling lumen 210 is a closed cavity within the expansion member 21, such that when the power member 22 is used to inject the fluid medium into the filling lumen 210 through the injection tube 211, the fluid medium gradually fills the filling lumen 210 without leaking. Since at least a part of the area on the outer wall surface of the expansion element 21 is the flexible area 212, the flexible area 212 is extruded and deformed and protrudes out of the outer wall surface of the expansion element 21 with the continuous filling of the fluid medium, so as to impact the ice layer on the outer wall surface of the expansion element 21, thereby ensuring that the ice layer on the expansion element 21 can be crushed and fall off, and achieving the purpose of deicing.

Illustratively, the power member 22 may be an air compressor or a power device such as a pump. When the power member 22 is an air compressor, the air outlet of the air compressor is communicated with the injection pipe 211 to inject air into the filling cavity 210 of the expansion member 21, i.e. the filling cavity 210 is gradually filled with air as a fluid medium. When the power member 22 is a pump, the liquid outlet of the pump communicates with the injection tube 211 to inject liquid into the filling lumen 210 of the expansion member 21, i.e., to gradually fill the filling lumen 210 with liquid as a fluid medium.

Illustratively, the power element 22 may also be a bottle with a fluid medium filled in the cavity. For example, the power member 22 may be a gas cylinder filled with air or other gas. When gas needs to be injected into the filling cavity 210 of the expansion member 21, the mouth of the gas cylinder can be communicated with the injection pipe 211, so as to achieve the purpose of injecting gas into the filling cavity 210.

Fig. 4 is a schematic structural diagram of an expansion member 21 according to an embodiment of the present disclosure. As shown in fig. 4, the expansion member 21 includes an expansion bladder including: the injection device comprises a bottom plate 213 and a flexible expansion leather 214, wherein the flexible expansion leather 214 is connected with the bottom plate 213 in a wrapping mode along the side edge of the bottom plate 213, the flexible expansion leather 214 and the bottom plate 213 enclose a filling inner cavity 210, an injection pipe 211 is located on the bottom plate 213, and the bottom plate 213 is connected with the outer wall surface of the box body 1 in a fitting mode.

In the above implementation manner, the fluid medium is continuously filled into the expansion bladder through the injection tube 211, and the flexible expansion skin 214 is extruded to deform and protrude out of the expansion bladder, so that the ice layer on the outer wall surface of the expansion bladder can be impacted, the ice layer on the expansion bladder can be crushed and fall off, and the purpose of deicing is achieved.

In addition, the bottom plate 213 of the expansion bladder, which has a hardness higher than that of the flexible expansion skin 214, is connected to the outer wall surface of the tank 1, so that it is possible to prevent the tank 1 from being pressed and protruded by the portion of the expansion bladder in contact with the tank 1 after the fluid medium is injected into the filling cavity 210 through the injection pipe 211.

As shown in fig. 4, the bottom plate 213 has a groove 218 on its surface opposite to the expansion bladder, so that the bottom plate 213 is integrally formed in a groove shape. The injection pipe 211 may be provided on a side wall of the bottom plate 213, and communicate with the groove 218 of the bottom plate 213 through a groove-shaped groove wall of the bottom plate 213. So that the injection tube 211 can be more reliably and stably fixed to the balloon.

Illustratively, the bottom plate 213 is a urethane rubber material. Among them, the polyurethane rubber is a series of elastomer materials containing more urethane groups on the polymer main chain. The polyurethane rubber has good wear resistance and strength. Therefore, the bottom plate 213 made of urethane rubber has good wear resistance and strength, and is not easily damaged.

Illustratively, the flexible intumescent skin 214 is a rubber bladder cloth. The rubber air bag cloth is a flexible material made of synthetic rubber, natural rubber and a fiber reinforced layer after vulcanization.

The rubber air bag cloth has good elasticity and is made of a material easy to deform, so that when the rubber air bag cloth is used as the flexible expansion leather 214, the flexible expansion leather 214 can deform easily and impact an ice layer on the expansion bag after the fluid medium is injected into the filling inner cavity 210. And the rubber air bag cloth has good elasticity and is not easy to crack after being deformed for many times, thereby improving the reliability of the expansion bag.

Thus, by arranging the expansion pieces 21 on the same side surface of the box body 1 and arranging the expansion pieces 21 at intervals, the expansion deformation of a plurality of areas on the same side surface of the box body 1 can occur together. Compared with the single expansion piece 21, the expansion deformation is only generated in a single area, the ice layer condensed on the expansion piece 21 is impacted from a plurality of areas, the possibility that the ice layer is broken after being impacted can be effectively improved, and the deicing efficiency is improved.

Wherein, still arrange connecting pipe 20 between two adjacent inflation pieces 21, communicate the filling inner chamber 210 of two adjacent inflation pieces 21 through connecting pipe 20, just need through power 22 to pour into fluid medium into injection pipe 211 like this, realize the purpose of filling fluid medium into the filling inner chamber 210 of a plurality of inflation pieces 21. To avoid the need to provide a plurality of injection pipes 211 for a plurality of expansion members 21, simplifying the structure and saving costs.

Illustratively, as shown in fig. 5, the expansion members 21 are strip-shaped, and the expansion members 21 on the same side of the case 1 are arranged in parallel at intervals.

The expansion piece 21 extends from one side to the other side of the box body 1, so that the expansion piece 21 can cover the side of the box body 1 to the maximum extent in the length direction of the expansion piece 21, and ice layers in all areas on the box body 1 are smashed and fall off under the impact.

As shown in fig. 3, three expansion pieces 21 are provided on the same side of the case 1, and the three expansion pieces 21 are arranged in parallel at intervals, and four connection pipes 20 are provided between two adjacent expansion pieces 21 to ensure that the fluid medium can be rapidly injected into the filling cavities 210 of the expansion pieces 21.

As shown in fig. 6, a plurality of block-shaped expansion pieces 21 are arrayed on the same side of the case 1, and a set of expansion pieces 21 having the same outline as the side of the case 1 is formed. The side of the box body 1 is rectangular, and correspondingly, the outline of a group of expansion pieces 21 distributed in an array on the side of the box body 1 is also rectangular. So that the expansion pieces 21 can cover the side surface of the box body 1 to the maximum extent, and the ice layer on each area of the box body 1 is crushed and dropped by the impact.

As shown in fig. 6, on the side of the case 1, there are four expansion members 21 in the lateral direction, and there are also four expansion members 21 in the longitudinal direction, that is, there are 16 expansion members 21 arranged in an array on the side of the case 1. A connecting tube 20 is provided between two expansion members 21 adjacent in the longitudinal direction, and a connecting tube 20 is also provided between two expansion members 21 adjacent in the transverse direction, to ensure that the fluid medium can be rapidly injected into the filling lumen 210 of the expansion members 21.

The first side surface 216 of the expansion box 215 is attached to the side surface of the box body 1, and the expansion box 215 covers the side surface of the box body 1 to prevent the side surface of the box body 1 from forming an ice layer and protect the box body 1.

Fig. 8 is a schematic structural diagram of another box 1 provided in the embodiment of the present disclosure. As shown in fig. 7 and 8, the second side 217 has a plurality of flexible regions 212 spaced apart.

The flexible region 212 may be a rubber air bag cloth embedded on the second side 217 of the expansion box 215, that is, the rubber air bag cloth also belongs to a part of the second side 217.

As shown in fig. 8, the profile of the entire expansion vessel 215 is the same as the side of the tank, i.e. the first side 216 of the expansion vessel 215 covers a substantial portion of the side of the tank.

And, a plurality of flexible regions 212 are provided on the second side 217 of the expansion box 215, so that when a fluid medium is injected into the expansion box 215 through the injection tube 211, the rubber bladders of the flexible regions 212 are deformed and impact the ice layer on the flexible regions 212 by being pressed by the fluid medium. Because there are a plurality of flexible areas 212, the flexible areas 212 are expanded and deformed together, so that the ice layer condensed on the expansion box 215 is impacted by the flexible areas 212, the possibility that the ice layer is broken after being impacted can be effectively improved, and the deicing efficiency is improved.

As shown in fig. 8, the flexible region 212 is a circular region, and since only the flexible region 212 is deformable in the expansion box 215, that is, the region outside the flexible region 212 has high hardness, if the flexible region 212 is formed in a polygonal shape such as a rectangle, the rubber airbag cloth in the flexible region 212 is easily torn when it is expanded and deformed. The flexible area 212 is set to be a circular area, so that the inner edge of the flexible area 212 is a circular arc surface, and thus the rubber airbag cloth is not easily torn when being pressed, expanded and deformed, and the reliability of the expansion box 215 is improved.

Compared with the scheme that a plurality of expansion pieces 21 are arranged on the side surface of the box body 1 at intervals, the scheme that the plurality of flexible areas 212 are arranged on the second side surface 217 of the expansion box 215 can avoid arranging the connecting pipes 20 for communicating the filling inner cavities 210 between the expansion pieces 21, simplify the structure of the expansion pieces 21 and reduce the cost.

Optionally, as shown in fig. 7, the expansion mechanism further comprises a vibration assembly 23, the vibration assembly 23 is located in the expansion box 215, and the vibration assembly 23 is used for driving the second side 217 to vibrate.

In this way, the vibrating assembly 23 can cause the second side 217 of the expansion box 215 to vibrate, and the vibrating second side 217 can shake off the ice layer adhered to the second side 217, so as to prevent the flexible area 212 from expanding and deforming and still being incapable of breaking the ice layer. At the same time, controlling the second side 217 to vibrate under the impact of the flexible region 212 can accelerate the shake-off of the ice layer located on the second side 217.

Illustratively, as shown in fig. 7, the vibration assembly 23 includes a cam 231 and a motor 232, the cam 231 is in transmission connection with an output shaft of the motor 232, a rotation central axis of the cam 231 is parallel to the second side 217, and the second side 217 is spaced from the rotation central axis of the cam 231 by a distance smaller than a maximum distance from an outer peripheral wall of the cam 231 to the rotation central axis of the cam 231.

Since the distance from the second side 217 to the rotation central axis of the cam 231 is smaller than the maximum distance from the outer circumferential wall of the cam 231 to the rotation central axis of the cam 231, the cam 231 intermittently strikes the second side 217 during the rotation of the cam 231, so that the second side 217 vibrates.

Thus, when the motor 232 rotates the cam 231, the rotating cam 231 intermittently contacts the second side 217 and strikes the second side 217, and at the same time, the cam 231 presses the second side 217 when contacting the crash pad, warping the second side 217, so that the cam 231 can continue to rotate, and when the cam 231 is no longer in contact with the second side 217, the second side 217 is restored, so that when the cam 231 is continuously driven to rotate by electricity, the second side 217 starts to vibrate, so that the ice layer adhered to the expansion box 215 is shaken off.

The cam 231 may be made of rubber, so that when the cam 231 contacts the second side 217, the cam 231 does not scratch the second side 217.

The disclosed embodiments provide a hydraulic system comprising a tank as described hereinbefore. The hydraulic system can comprise a hydraulic pump and hydraulic equipment driven by the hydraulic pump, an oil inlet of the hydraulic pump is communicated with the oil tank, and an oil outlet of the hydraulic pump is communicated with the hydraulic equipment through a pipeline, so that the hydraulic pump can extract oil in the oil tank to supply oil for the hydraulic equipment.

This hydraulic system's oil tank setting and boats and ships on the deck, when a boats and ships navigation in alpine sea area, and the shell of oil tank is iced, can control power component 22 and switch expansion piece 21 to first state from the second state, so that expansion piece 21's volume grow, make expansion piece 21 quick arch on the shell of oil tank promptly, make expansion piece 21 impact snow or the ice sheet on expansion piece 21, thereby make snow or the ice sheet cracked to drop, reach the purpose of quick deicing.

Meanwhile, the expansion piece 21 can be repeatedly switched between the first state and the second state through the power piece 22, so that the accumulated snow or the ice layer on the expansion piece 21 can be repeatedly impacted by the expansion piece 21, the accumulated snow or the ice layer on the expansion piece 21 can be broken and dropped, and the deicing effect is ensured. Compared with the ice melting mode adopting a heating device, the ice melting device does not need to be additionally arranged, so that the ice removing cost can be greatly reduced, and the ice melting device is convenient to use.

Although the present disclosure has been described with reference to specific embodiments, it will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the disclosure.
