Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of fuel delivery, and particularly to a fuel filling device. Background Art
[0002] LPG is the abbreviation of liquefied petroleum gas. The main components of LPG are propane and butane, with a small amount of olefins. As a clean energy source, LPG is a gas under normal temperature and pressure, and is liquefied by pressurization or cooling for easy storage and transportation. LPG is stored in a storage tank in a liquid state under appropriate pressure to provide fuel for automobiles and ships. When providing LPG fuel for ships, a special fuel filling system device is usually used. The fuel enters the ship after being transferred by the filling device, so as to ensure the safe and efficient filling of liquefied petroleum gas into the ship's storage tank. However, there are many problems with the existing fuel filling system devices.
[0003] The existing filling devices have problems such as many transmission components, large size, and time-consuming and laborious use, which bring inconvenience to actual operation. In addition, the existing filling devices cannot maximize the discharge of the remaining liquefied petroleum gas inside after filling, which also brings inconvenience to actual operation.

A piston plate is slidably installed in the storage tank, and the piston plate can move along the height direction of the storage tank. The piston plate, the side wall of the storage tank, and the top plate of the storage tank enclose a containing cavity.

The moving block with a threaded hole is installed in the long slot, and the screw rod passes through the threaded hole. A connecting rod is connected between the moving block and the side wall of the storage tank. When the screw rod rotates, the moving block moves along the long slot, and then the flipping angle of the storage tank is changed under the pulling of the connecting rod.

[0026] Embodiment 1
[0027] As Figures 1 to 3 shown, this embodiment provides a fuel filling device, including:
[0028] Storage box 1, the lower edge of the side wall of the storage box 1 is installed with a connecting plate 2 through a flipping component. When the connecting plate 2 is in a horizontal state, the storage box 1 can flip relative to the connecting plate 2;
[0029] A liquid injection pipe 3 is provided on the side wall of the storage box 1, a filling pipe is installed on the top plate of the storage box 1, a piston plate 4 is slidably installed in the storage box 1, and the piston plate 4 can move along the height direction of the storage box. The piston plate 4, the side wall of the storage box 1, and the top plate of the storage box 1 enclose a containing cavity. Liquid fuel enters the containing cavity of the storage box 1 through the liquid injection pipe 3 and is injected into the filling port of the ship storage tank through the filling pipe.
[0030] Further, a push rod 5 is fixed to the bottom surface of the piston plate 4, and the push rod 5 penetrates downward through the bottom plate of the storage box 1. The push rod 5 is used to push the piston plate 4 upward to compress the space of the containing cavity to empty the fuel.
[0031] Further, a valve is installed on the liquid injection pipe 3.
[0032] Further, the flipping component includes a rotating shaft, a screw rod 7, a moving block, and a connecting rod 10. The storage box 1 and the connecting plate 2 flip relative to the rotating shaft. A long slot 8 is opened inside the connecting plate 2, and the long slot 8 is perpendicular to the rotating shaft. The screw rod 7 is installed in the long slot 8, and both ends of the screw rod 7 are movably connected to the inner walls on both sides of the long slot 8. A moving block provided with a threaded hole is installed in the long slot, and the screw rod 7 penetrates through the threaded hole. A connecting rod 10 is connected between the moving block and the side wall of the storage box. When the screw rod 7 rotates, the moving block moves along the long slot, and then the flipping angle of the storage box 1 is changed under the pulling of the connecting rod 10.
[0033] Further, a connecting shaft 9 is fixedly extended at the end of the screw rod 7 away from the storage box 1, and the connecting shaft 9 can drive the screw rod 7 to rotate synchronously.
[0034] Further, a vertical lifting component, that is, a lifting rod 6, is fixed to the bottom surface of the connecting plate 2. The lifting component stands vertically beside the ship. By changing the height of the connecting plate 2 and cooperating with flipping the storage box 1, the filling pipe is aligned with the filling port of the ship storage tank.
[0035] Further, an inclined plate 11 is fixed to the top edge of the piston plate 4 away from the push rod 5, and the inclined plate 11 is used to collect the fuel in the containing cavity to the central area of the piston plate 4.
[0036] Further, an inclination sensor is installed on the storage box 1, which can detect the rotation angle of the storage box 1. The lifting rod is installed beside the ship and is connected to a controller (such as a PLC). A distance sensor is installed at the filling port of the ship storage tank. The distance sensor detects the height of the storage box and transmits the signal to the controller, and the controller controls the lifting rod to extend or contract.
[0037] During the fuel filling process, the lifting rod 6 can be fixedly installed beside the ship. When the storage tank 1 is flipped to the upright state, the push rod 5 will not collide with the lifting assembly. The fuel is injected into the storage tank 1 through the liquid injection pipe 3. When fuel needs to be filled, according to the position of the filling port, the storage tank 1 is controlled to flip to adjust the position of the filling pipe, facilitating better injection of the fuel from the filling port into the ship's fuel storage tank. The lifting assembly includes a lifting rod 6, and the top end of the movable end of the lifting rod 6 is fixedly connected to the bottom surface of the connecting plate 2. By extending or contracting the lifting rod 6, the height changes of the connecting plate 2 and the storage tank 1 can be adjusted, and the adjustment is made according to the height of the filling port.
[0038] When the filling is completed, the push rod 5 is used to push the piston plate 4 upward to compress the space of the accommodating cavity to empty the fuel. In addition, during the filling process, the push rod 5 can also be pushed to adjust the internal space of the accommodating cavity. The accommodating cavity here plays a role of intermediate transfer and filtration. Impurities in the fuel will precipitate when passing through the accommodating cavity, thus playing a certain filtering role. In addition, using this filling device as an intermediate device between the fuel supply pipeline and the filling port can improve the stability and safety of the filling process.
[0039] In summary, the present invention provides a fuel filling device, which includes a storage tank and a connecting plate installed at the lower edge of the side wall of the storage tank. The storage tank is connected to the connecting plate through a flipping assembly and the storage tank can flip relative to the connecting plate. A liquid injection pipe is provided on the side wall of the storage tank, and a filling pipe is installed on the top plate of the storage tank. The liquid fuel enters the accommodating cavity of the storage tank through the liquid injection pipe and is injected into the filling port of the ship's storage tank through the filling pipe. A vertical lifting assembly is fixed to the bottom surface of the connecting plate. The lifting assembly stands vertically beside the ship. By changing the height of the connecting plate and cooperating with flipping the storage tank, the filling pipe is aligned with the filling port of the ship's storage tank, facilitating better injection of the fuel from the filling port into the ship's fuel storage tank. In addition, by moving the piston plate, the space of the accommodating cavity can also be compressed to empty the fuel. This filling device is easy to manufacture and has simple operation, and can significantly improve the stability and safety of the fuel filling process.
