Background

With the development of social economy, the continuous improvement of the living standard of people and the popularization of lamplight purse seiner, more and more small and medium ships with various different purposes appear in seaside, inland lakes, reservoirs and rivers, and as the small and medium ships move in the near-shore water area throughout the year, the small and medium ships cannot be refueled to a gas station like an automobile and cannot be refueled by a special refuelling vehicle like a large ship, so that the difficult problem of refueling is caused. At present, for small and medium-sized ships, the refueling mode commonly adopted by people is as follows: firstly, preparing common oil barrels, loading the oil barrels by a truck to a gas station, filling the oil barrels with oil, then pulling the oil barrels to a shore or a wharf by the truck, and adding the oil into an oil tank in a ship through a manual oil pump and an oil delivery hose; or the small-capacity oil drum is directly carried by hand and directly filled with an oil receiving port of an onboard oil tank through an oil outlet of the oil drum; or one section of the oil delivery hose is firstly inserted into the oil drum, an oil filler firstly sucks air in the hose by a mouth, and oil is added into the oil tank in the ship by means of the siphon principle. The refueling method generally has the problem of fuel leakage in the refueling process: (1) oil is added into an oil tank in a ship through a manual oil pump and an oil delivery hose, and because the oil delivery hose is long, fuel oil in the hose cannot be emptied after the oil is added, so that when the hose is coiled, residual fuel oil in the hose is scattered into a water body, on a near bank and on a wharf, and the water body environment and the near bank wharf environment are polluted; (2) the oil outlet of the oil drum and the oil receiving port of the oil tank on the ship are directly filled, and the oil outlet and the oil receiving port cannot be completely aligned due to the self shaking of the ship body, so that a large amount of fuel oil is leaked to enter the ship body and a water area, and the environment is polluted; (3) when oil is added into an oil tank in a ship by means of a siphon principle, an oiling worker can not avoid sucking part of fuel oil into a suction port and can not avoid spitting out the fuel oil, and therefore the water body is polluted and the ship is not sanitary.

The specific using process is as follows: mention full oil drum 1 to place oil drum 1 on base on-off mechanism according to a plurality of stopper 7 and the one-to-one relation of a plurality of spacing grooves 10 of supporting, guarantee to interface shell 12 corresponding with funnel 17, will support stopper 7 and be fixed in on bottom plate 8 through a plurality of connecting bolt, realize oil drum 1 and base on-off mechanism's fixed. One end of the oil pipe 19 is arranged on the oil pipe mounting opening 18 below the base switch mechanism, the other end of the oil pipe is connected with an oil receiving hole of an oil tank of a small and medium-sized ship, when oiling operation is not performed, the spring is always in a stretching state, the sealing part 15 is subjected to downward force, and the sealing cover 151 seals the top of the annular channel 24 to ensure that oil cannot leak.

When the oiling operation is carried out, the vent hole is opened by stirring the cover plate 5, the opening of the vent hole ensures that the oil can smoothly flow out, a downward force is applied to a pedal 95 in the pedal link assembly 9, the second link 94 rotates the first link 93, thereby pulling the vertical rod 92 and the horizontal rod 91 to move upwards, the horizontal rod 91 drives the thimble 22 to move upwards, the thimble 22 is connected with the vertical column 152 of the sealing component 15 when moving, and pushes the vertical column 152 to move upwards, the spring continues to be stretched, due to the support of the vertical column 152 by the ejector pin 22, the sealing cap 151 leaves the top of the annular channel 24, no longer seals against the top of the annular channel 24, so that oil can flow out of the annular channel 24, and flow along the funnel 17 into the oil pipe 19 below the base switching mechanism, the oiling operation is realized, and in addition, the sealing ring 96 is arranged at the position of the vertical rod 92, so that the vertical rod 92 is ensured not to overflow oil when moving upwards.

After the oiling operation is completed, the force application to the pedal 95 of the pedal connecting rod assembly 9 is stopped, the vertical rod 92, the horizontal rod 91 and the ejector pin 22 fall back under the action of gravity, the vertical column 152 loses support and falls back under the pulling of a spring, so that the sealing cover 151 reseals the top of the annular channel 24, and oil cannot flow out; and opening the oil filling cover 3 to supplement oil into the oil drum 1 through the oil filling port 2 to wait for next oil filling operation.

The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
