[0004] However, the current liquid fuel filling equipment has the following problems: The liquid fuel filling equipment manually connects the oil pipe and the filling head by the staff and the user. Therefore, the oil pipe and the filling head may fall into the river due to the mistakes of the staff and the user. Moreover, the oil pipe hanging on the river will shake due to a sudden strong wind, resulting in the problem that the connection between the filling head and the filling pipe of the ship is unstable. Therefore, we propose a liquid fuel filling equipment for the green energy filling of ships. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a liquid fuel filling equipment for the green energy filling of ships, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A liquid fuel filling device for ship green energy filling, including a fixed frame, the inner wall of the fixed frame is fixedly connected with a liquid storage container, the top of the liquid storage container is fixedly connected with an oil pipe, one end of the oil pipe away from the liquid storage container is fixedly connected with a filling head, the top of the liquid storage container is fixedly connected with a filling pump, the top of the liquid storage container is fixedly connected with a liquid inlet pipe, a pushing device is arranged on the outer wall of the fixed frame, the pushing device includes a fixing plate, the side of the fixing plate is fixedly connected to the outer wall of the fixed frame, the top of the fixed frame is fixedly connected with a universal bladder, the top of the universal bladder is fixedly connected with a connecting plate, a U-shaped clamping rod is inserted into the side of the connecting plate, one end of the U-shaped clamping rod away from the connecting plate is inserted into the side of the fixed frame, the side of the connecting plate is fixedly connected with a telescopic plate, the side of the connecting plate is fixedly connected with an electric push rod, the telescopic end of the electric push rod is fixedly connected with a fixing block, the top of the fixing block is fixedly connected to the bottom of the telescopic end of the telescopic plate, the top of the fixed end of the telescopic plate is fixedly connected with a support block one, the inner wall of the support block one is fixedly connected to the outer wall of the oil pipe, the top of the telescopic end of the telescopic plate is fixedly connected with a support block two, an arc block is fixedly connected to the outer wall of the oil pipe, the arc block and the support block two are connected by bolts, the side of the support block two is fixedly connected with a protective cylinder. When the user inserts the filling head into the vertically arranged filling pipe of the ship, and then starts the filling pump, the filling pump fills the liquid storage container through the oil pipe from the filling head into the filling pipe of the ship. When preparing to send the filling head to the user's hand, start the electric push rod, the telescopic end of the electric push rod will drive the telescopic end of the telescopic plate to move. When the telescopic end of the telescopic plate moves, it will drive the support block two to move. The movement of the support block two drives the arc block to move through the bolt. The movement of the arc block will push the oil pipe and the filling head towards the user. When the oil pipe and the filling head reach in front of the user, the user turns the bolt so that the bolt contacts the push frame, so that the support block two and the arc block are separated. Then the user inserts the filling head into the filling pipe of the ship. At the same time, the movement of the support block two will drive the protective cylinder to move. Therefore, the protective cylinder can protect the oil pipe hanging on the river.

[0007] According to the above technical solution, a sealing bladder is fixedly connected to the outer wall of the filling head, and a push frame is fixedly connected to the side of the sealing bladder. When the filling head is inserted into the filling pipe of the ship, the filling head will drive the sealing bladder to contact the inner wall of the ship filling pipe, and then continue to turn the bolt, and the bolt will push the push frame to squeeze the sealing bladder.

[0008] According to the above technical solution, a plurality of annular rubber rings are fixedly connected to the outer wall of the sealing capsule, and two grips are fixedly connected to the outer wall of the pushing frame. After the filling is completed, the staff turns the bolt in the reverse direction so that the sealing capsule and the annular rubber rings are no longer in contact with the inner wall of the filling pipe. Then the staff holds the grips and drives the filling head to shake up and down through the grips, the pushing frame, and the sealing capsule.

[0009] According to the above technical solution, the pushing frame is located on the displacement track of the bolt, and the inner wall of the pushing frame is in contact with the outer wall of the oil pipe.

[0010] According to the above technical solution, the outer wall of the oil pipe is in contact with the inner wall of the protective cylinder, and the first support block is located on the displacement track of the protective cylinder.

[0011] According to the above technical solution, an anti-pulling device is arranged at the top of the telescopic end of the telescopic plate. The anti-pulling device includes a U-shaped cavity block, the bottom of the U-shaped cavity block is fixedly connected to the top of the telescopic end of the telescopic plate, a moving plate is slidably connected to the inner wall of the U-shaped cavity block, a connecting rod is fixedly connected to the bottom of the moving plate, an adsorption plate is fixedly connected to the bottom of the connecting rod, an air pipe is fixedly connected to the lower side of the U-shaped cavity block, and the air pipe is fixedly connected to the side of the adsorption plate away from the U-shaped cavity block. The outer wall of one end of the oil pipe close to the liquid storage container is arranged in a folded shape. When the telescopic end of the telescopic plate moves, it will push the U-shaped cavity block together. After the user inserts the filling head into the filling pipe of the ship, then the user takes the clamping rod away from between the limiting block and the fixed block, and takes the U-shaped clamping rod away from between the fixing plate and the connecting plate. Then the user pushes the limiting block downward. The downward movement of the limiting block drives the adsorption plate to move downward. The downward movement of the adsorption plate drives the connecting rod to move downward. The downward movement of the connecting rod drives the moving plate to move downward along the inner wall of the U-shaped cavity block, so that the U-shaped cavity block extracts the air at the adsorption plate through the air pipe, so that negative pressure is generated at the suction nozzle of the adsorption plate. At the same time, when the ship to be filled is shaken by the wind and waves, since the adsorption plate fixes the telescopic plate to the ship to be filled, when the ship to be filled is shaken by the wind and waves, it will drive the adsorption plate to shake synchronously. The shaking of the adsorption plate drives the connecting rod, the moving plate, and the U-shaped cavity block to shake synchronously. The shaking of the U-shaped cavity block drives the telescopic plate to shake synchronously. The shaking of the telescopic plate will cause the connecting plate to shake synchronously on the top of the universal capsule body. At the same time, the telescopic plate will cause the first support block to shake the folded part of the oil pipe.

[0012] According to the above technical solution, a limiting block is fixedly connected to the top of the adsorption plate, and the limiting block is connected to the fixed block through a clamping rod.

[0013] According to the above technical solution, the outer wall of the connecting rod is in contact with the lower inner wall of the U-shaped cavity block.

[0014] The present invention provides a liquid fuel filling device for filling green energy for ships, which has the following beneficial effects:

[0015] (1) The present invention avoids the problem that the oil pipe and the filling head are manually connected by the staff and the user, and the oil pipe and the filling head fall into the river due to the mistakes of the staff and the user, through the coordination of the telescopic plate, the electric push rod, the fixed block, the support block 1, the support block 2, the arc block, the bolts and the protective cylinder. At the same time, the movement of the support block 2 will drive the movement of the protective cylinder, so that the protective cylinder can protect the oil pipe hanging on the river, thereby avoiding the problem that the sudden strong wind causes the oil pipe to shake, resulting in the unstable connection between the filling head and the filling pipe of the ship; at the same time, through the coordination of the filling head, the sealing bag and the bolts, the bolts push the push frame to squeeze the sealing bag, so that the sealing bag is deformed and hits the inner wall of the filling pipe, so that the filling head inserted into the filling pipe is positioned and fixed.

[0016] (2) The present invention cooperates with the sealing bag and the annular rubber ring so that when the sealing bag expands, the annular rubber ring will be driven to contact the inner wall of the filling pipe. When the annular rubber ring contacts the inner wall of the filling pipe, the friction force can be increased to help the sealing bag to remain stably on the inner wall of the filling pipe, thereby preventing the sealing bag from being displaced or offset after expansion. In addition, the durability and reliability of the use of the sealing bag are enhanced through the effect of friction. At the same time, through the cooperation of the bolts, the sealing bag, the annular rubber ring, and the filling head handle, the staff can hold the handle and use the handle to drive the push frame and the sealing bag to swing the filling head up and down. The up and down swinging of the filling head will cause the liquid fuel remaining in the filling head to drip into the filling pipe, thereby ensuring that the liquid fuel fully enters the filling pipe.

[0017] (3) The present invention cooperates with the U-shaped cavity block, the movable plate, the connecting rod, the adsorption plate, the air pipe, the limiting block and the clamping rod to enable the connecting rod to move downward, driving the movable plate to move downward along the inner wall of the U-shaped cavity block, so that the U-shaped cavity block draws air from the adsorption plate through the air pipe, thereby generating negative pressure at the suction nozzle of the adsorption plate. The suction nozzle of the adsorption plate adsorbs and fixes the surface of the ship, thereby reinforcing and fixing the telescopic plate, thereby ensuring the stability of the filling of the filling head; at the same time, through the cooperation of the adsorption plate, the telescopic plate, the connecting rod, the movable plate, the U-shaped cavity block and the universal bladder, when the filling pipe of the ship is filled, the filling head will not be affected by the shaking of the ship, which will cause problems in the filling of the filling head, and through the setting of the folding part of the universal bladder and the oil pipe, it can be ensured that the shaking of the ship in all directions will not affect the filling of the filling head.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Please refer to Figures 1-7, an embodiment of the present invention is: a liquid fuel filling device for green energy filling of ships, including a fixed frame 1. The inner wall of the fixed frame 1 is fixedly connected with a liquid storage container 2. The top of the liquid storage container 2 is fixedly connected with an oil pipe 3. One end of the oil pipe 3 away from the liquid storage container 2 is fixedly connected with a filling head 4. The top of the liquid storage container 2 is fixedly connected with a filling pump 5. The top of the liquid storage container 2 is fixedly connected with a liquid inlet pipe. The outer wall of the fixed frame 1 is provided with a pushing device 6. The pushing device 6 includes a fixing plate 61. The side of the fixing plate 61 is fixedly connected to the outer wall of the fixed frame 1. The top of the fixed frame 1 is fixedly connected with a universal bladder 62. The top of the universal bladder 62 is fixedly connected with a connecting plate 63. A U-shaped clamping rod 64 is inserted into the side of the connecting plate 63. One end of the U-shaped clamping rod 64 away from the connecting plate 63 is inserted into the side of the fixed frame 1. The side of the connecting plate 63 is fixedly connected with a telescopic plate 65. The side of the connecting plate 63 is fixedly connected with an electric push rod 66. The telescopic end of the electric push rod 66 is fixedly connected with a fixing block 67. The top of the fixing block 67 is fixedly connected to the bottom of the telescopic end of the telescopic plate 65. The top of the fixed end of the telescopic plate 65 is fixedly connected with a support block one 68. The inner wall of the support block one 68 is fixedly connected to the outer wall of the oil pipe 3. The top of the telescopic end of the telescopic plate 65 is fixedly connected with a support block two 69. An arc block 610 is fixedly connected to the outer wall of the oil pipe 3. The arc block 610 and the support block two 69 are connected by a bolt 611. The side of the support block two 69 is fixedly connected with a protective cylinder 612. Through the setting of the above structure, the support block two 69 and the arc block 610 are separated. Then, the user inserts the filling head 4 into the filling pipe of the ship, avoiding the artificial handling of the oil pipe 3 and the filling head 4 by the staff and the user, and preventing the problem that the oil pipe 3 and the filling head 4 fall into the river due to the mistakes of the staff and the user. At the same time, the movement of the support block two 69 will drive the protective cylinder 612 to move. Therefore, the protective cylinder 612 can protect the oil pipe 3 hanging on the river, thus avoiding the problem that the sudden strong wind causes the oil pipe 3 to shake, resulting in unstable connection between the filling head 4 and the filling pipe of the ship.

[0028] The outer wall of the filling head 4 is fixedly connected with a sealing capsule 613. The side surface of the sealing capsule 613 is fixedly connected with a pushing frame 614. The pushing frame 614 is located on the displacement track of the bolt 611. The inner wall of the pushing frame 614 is in contact with the outer wall of the fuel pipe 3. Through the setting of the above structure, the sealing capsule 613 deforms and abuts against the inner wall of the filling pipe, thereby positioning and fixing the filling head 4 inserted into the filling pipe. At the same time, when the sealing capsule 613 expands, it will drive the annular rubber ring 615 to contact the inner wall of the filling pipe. When the annular rubber ring 615 contacts the inner wall of the filling pipe, it can increase the friction force, help the sealing capsule 613 to stably stay on the inner wall of the filling pipe, prevent the sealing capsule 613 from shifting or deviating after expansion, and through the action of the friction force, enhance the durability and reliability of the sealing capsule 613. And the staff holds the grip 616, and through the grip 616, the pushing frame 614 and the sealing capsule 613 drive the filling head 4 to swing up and down. The up and down swing of the filling head 4 will drip the remaining liquid fuel inside the filling head 4 into the filling pipe, so as to ensure that the liquid fuel fully enters the filling pipe.

[0029] During use, the user inserts the filling head 4 into the filling pipe vertically arranged on the ship, and then starts the filling pump 5. The filling pump 5 fills the liquid storage container 2 from the filling head 4 to the filling pipe of the ship through the oil pipe 3. When the filling head 4 is ready to be delivered to the user, the electric push rod 66 is started, and the telescopic end of the electric push rod 66 drives the telescopic end of the telescopic plate 65 to move. When the telescopic end of the telescopic plate 65 moves, it drives the support block 2 69 to move. The movement of the support block 2 69 drives the arc block 610 to move through the bolt 611. The movement of the arc block 610 pushes the oil pipe 3 and the filling head 4 to the user. When the oil pipe 3 and the filling head 4 are in contact with each other, the user can move the oil pipe 3 and the filling head 4 to the user. When the filling head 4 reaches the user, the user screws the bolt 611 to make the bolt 611 contact with the push frame 614, so as to separate the supporting block 2 69 from the arc block 610, and then the user inserts the filling head 4 into the filling pipe of the ship, thereby avoiding the problem that the staff and the user manually take the oil pipe 3 and the filling head 4 and cause the oil pipe 3 and the filling head 4 to fall into the river due to the mistakes of the staff and the user. At the same time, the movement of the supporting block 2 69 will drive the protective tube 612 to move, so the protective tube 612 can protect the oil pipe 3 hanging on the river, thereby preventing the sudden strong wind from shaking the oil pipe 3. This leads to the problem of unstable connection between the filling head 4 and the filling pipe of the ship; when the filling head 4 is inserted into the filling pipe of the ship, the filling head 4 will drive the sealing bag 613 to contact the inner wall of the filling pipe of the ship, and then continue to tighten the bolt 611, the bolt 611 will push the push frame 614 to squeeze the sealing bag 613, so that the sealing bag 613 is deformed and contacts the inner wall of the filling pipe, so as to position and fix the filling head 4 inserted into the filling pipe; at the same time, when the sealing bag 613 expands, it will drive the annular rubber ring 615 to contact the inner wall of the filling pipe. When the annular rubber ring 615 contacts the inner wall of the filling pipe, it can increase the friction and help seal. The capsule 613 is stably maintained on the inner wall of the filling tube to prevent the sealing capsule 613 from being displaced or offset after expansion, and the durability and reliability of the use of the sealing capsule 613 are enhanced through the effect of friction. When the filling is completed, the staff twists the bolt 611 in the opposite direction to make the sealing capsule 613 and the annular rubber ring 615 no longer contact the inner wall of the filling tube. Then the staff holds the handle 616 and uses the handle 616 to drive the push rack 614 and the sealing capsule 613 to drive the filling head 4 to shake up and down. The up and down shaking of the filling head 4 will drip the remaining liquid fuel inside the filling head 4 into the filling tube, thereby ensuring that the liquid fuel fully enters the filling tube.

[0030] See also Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, a anti-pulling device 7 is provided at the top of the telescopic end of the telescopic plate 65. The anti-pulling device 7 includes a U-shaped cavity block 71. The bottom of the U-shaped cavity block 71 is fixedly connected to the top of the telescopic end of the telescopic plate 65. A moving plate 72 is slidably connected to the inner wall of the U-shaped cavity block 71. A connecting rod 73 is fixedly connected to the bottom of the moving plate 72. A suction plate 74 is fixedly connected to the bottom of the connecting rod 73. An air pipe 75 is fixedly connected to the lower side of the side surface of the U-shaped cavity block 71. The air pipe 75 is fixedly connected to the side surface of the suction plate 74 away from the U-shaped cavity block 71. The outer wall of one end of the oil pipe 3 close to the liquid storage container 2 is arranged in a folded shape. A limiting block 76 is fixedly connected to the top of the suction plate 74. The limiting block 76 is connected to the fixed block 67 through a clamping rod 77. The outer wall of the connecting rod 73 is in contact with the lower inner wall of the U-shaped cavity block 71. Through the setting of the above structure, the U-shaped cavity block 71 extracts the air at the suction plate 74 through the air pipe 75, so that a negative pressure is generated at the suction nozzle of the suction plate 74. The suction nozzle of the suction plate 74 will adsorb and fix the ship surface, so as to reinforce and fix the telescopic plate 65, so as to ensure the stability of the filling head 4 during filling. At the same time, the shaking of the telescopic plate 65 will cause the connecting plate 63 to shake synchronously on the top of the universal airbag 62. At the same time, the telescopic plate 65 will also cause the support block one 68 to shake the folded part of the oil pipe 3, so as to ensure that when the filling head 4 fills the filling pipe of the ship, the filling head 4 will not be affected by the shaking of the ship and cause problems during filling; and through the setting of the universal airbag 62 and the folded part of the oil pipe 3, it can be ensured that the filling head 4 will not be affected when the ship shakes in all directions.

[0031] During use, when the telescopic end of the telescopic plate 65 moves, it will push the U-shaped cavity block 71 together. After the user inserts the filling head 4 into the filling pipe of the ship, then the user removes the clamping rod 77 from between the limiting block 76 and the fixed block 67, and removes the U-shaped clamping rod 64 from between the fixed plate 61 and the connecting plate 63. Then the user pushes the limiting block 76 downward. The downward movement of the limiting block 76 drives the adsorption plate 74 to move downward. The downward movement of the adsorption plate 74 drives the connecting rod 73 to move downward. The downward movement of the connecting rod 73 drives the moving plate 72 to move downward along the inner wall of the U-shaped cavity block 71, so that the U-shaped cavity block 71 extracts the air at the adsorption plate 74 through the air pipe 75, so that a negative pressure is generated at the nozzle of the adsorption plate 74. The nozzle of the adsorption plate 74 will adsorb and fix the ship surface, so as to reinforce and fix the telescopic plate 65, so as to ensure the stability of the filling of the filling head 4; when the ship to be filled sways due to wind and waves, since the adsorption plate 74 fixes the telescopic plate 65 to the ship to be filled, when the ship to be filled sways due to wind and waves, it will drive the adsorption plate 74 to sway synchronously. The swaying of the adsorption plate 74 drives the connecting rod 73, the moving plate 72, and the U-shaped cavity block 71 to sway synchronously. The swaying of the U-shaped cavity block 71 drives the telescopic plate 65 to sway synchronously. The swaying of the telescopic plate 65 will cause the connecting plate 63 to sway synchronously on the top of the universal airbag 62. At the same time, the telescopic plate 65 will also cause the support block 1 68 to sway the folded part of the oil pipe 3, so as to ensure that when the filling head 4 fills the filling pipe of the ship, the filling head 4 will not have problems due to the swaying of the ship; and through the setting of the universal airbag 62 and the folded part of the oil pipe 3, it can be ensured that the filling head 4 will not be affected when the ship sways in all directions.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
