In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0024] like Figure 1-Figure 3As shown, an embodiment of the present invention provides a ship filling system, including a shore filling station 1, a filling pipe 81, a bracket 2, a connecting elbow, a buffer room 62, an airlock room 63 and a shipboard filling station 7. The filling pipe 81 is used to connect the shore filling station 1 and the shipboard filling station 7. The filling pipe 81 passes through the vehicle cabin 61, the buffer room 62 and the airlock room 63 from the shore filling station 1 to enter the shipboard filling station 7. The buffer room 62 is used to balance the pressure difference between the inside and outside of the shipboard filling station 7 to reduce the impact of pressure fluctuations on the shipboard filling station 7 and related equipment. The airlock room 63 is used to achieve isolation and airflow control between different areas to reduce the risk of untreated outside air directly entering the key area. The connecting elbow is set at the turning point of the filling pipe 81. The bracket 2 is respectively set at the step where the filling pipe 81 enters the vehicle cabin 61, the step where the vehicle cabin 61 enters the buffer room 62, the step where the buffer room 62 enters the airlock room 63, and the step where the airlock room 63 enters the shipboard filling station 7. The bracket 2 is used to lift the filling pipe 81 to smoothly pass through each step. By setting the above filling system, the stern of the ship is close to the shore filling station 1 to achieve loading and unloading of cargo and filling of fuel at the same time, which is simple to operate, efficient and relatively low in cost.

[0025] Specifically, one end of the filling pipe 81 is connected to the shore filling station 1, and then passes through the ship's railing to enter the vehicle cabin 61 of the ship. When entering the vehicle cabin 61, since a relatively high step is provided at the entrance of the vehicle cabin 61, a bracket 2 is provided at the step for entering the vehicle cabin 61, and the filling pipe 81 is lifted up by the bracket 2, so that the vehicle cabin 61 can be smoothly entered. In order to facilitate the arrangement of the filling pipe 81, the filling pipe 81 can be fixedly arranged along one side wall of the vehicle cabin 61. When the filling pipe 81 extends to the direction in which the vehicle cabin 61 is flush with the onboard filling station 7, it is necessary to turn in order to continue to extend toward the onboard filling station 7. According to the technical requirements for the arrangement of the filling pipe 81, a connecting elbow needs to be provided at the turning point to connect the filling pipes 81 in two directions. The connecting elbow can be a right-angle elbow. When the filling pipe 81 extending in the direction of the onboard filling station 7 enters the buffer room 62 from the vehicle cabin 61, since a relatively high step is also provided at the entrance of the buffer room 62, a bracket 2 is also provided at the step where the vehicle cabin 61 enters the buffer room 62. Similarly, a bracket 2 is also provided at the step where the buffer room 62 enters the airlock room 63 and the step where the airlock room 63 enters the onboard filling station 7. Thus, the filling pipe 81 can smoothly enter the buffer room 62, the airlock room 63 and the onboard filling station 7. After entering the onboard filling station 7, the filling pipe 81 needs to gradually rise along the side railing to communicate with the interface of the onboard filling station 7. Therefore, a turning point is required when the filling pipe 81 enters the onboard filling station 7 from the airlock room 63 and extends toward the side railing, and when the filling pipe 81 is set on the side railing and extends to the interface of the onboard filling station 7. Correspondingly, a connecting elbow is also provided at the turning point. When the filling pipe 81 is arranged on the side railing and extends toward the interface of the filling station 7 on board the ship, two turning points may be arranged.

[0026] Furthermore, both the buffer room 62 and the air lock room 63 can realize their own functions by arranging fans inside.

[0027] In some embodiments of the present invention, the filling system further comprises a saddle 3, which is arranged on the deck near the position where the filling pipe 81 is set on the ship railing. The saddle 3 is used to support the filling pipe 81 to prevent the filling pipe 81 from having an excessively large bending radius.

[0028] Specifically, a saddle 3 is provided on the deck near the railing where the filling pipe 81 enters the ship, and after the filling pipe 81 enters the onboard filling station 7, a saddle 3 is provided on the deck along the interface connection between the railing and the onboard filling station 7. The saddle 3 includes a base 31, a seat body 32, a support panel 33 and a limiter 34. The base 31 is placed on the deck, and the seat body 32 is vertically fixed on the upper surface of the base 31. The support panel 33 is provided on the top of the seat body 32 and is an overall curved surface structure that bulges upward. The filling pipe 81 can be mounted on the support panel 33 and extend along the curved surface of the support panel 33, thereby supporting the filling pipe 81. The limiter 34 is provided on both sides of the support panel 33, which serves to limit the position of the filling pipe 81 and prevent the filling pipe 81 from falling off the saddle 3.

[0029] Furthermore, a diagonal brace 37 is provided on the side wall of the seat body 32 to improve the stability of the seat body 32 when placed.

[0030] Furthermore, the limiting portion 34 includes two limiting plates, and the two limiting plates are respectively fixedly disposed on two sides of the supporting panel 33 .

[0031] Furthermore, the seat body 32 includes a vertical rod 321 and a cross rod 322. The vertical rod 321 is vertically arranged on the base 31, and the cross rod 322 is horizontally arranged on the middle side wall of the vertical rod 321. The saddle 3 also includes a flip base 35 and a flip bracket 36. The flip base 35 is fixedly arranged on the cross rod 322, one end of the flip bracket 36 is rotatably connected to the flip base 35, and the other end is hinged on the support panel 33, so that the support panel 33 can rotate around the flip base 35.

[0032] The saddle 3 also includes bolts and nuts. The seat body 32 is provided with through holes, and the support panel 33 is provided with a plurality of insertion holes 331 along the rotation track direction of the support panel 33, so that when the support panel 33 is rotated to the insertion holes 331 and the through holes are on the same axis, the bolts can be inserted into the through holes and the insertion holes 331, and then the support panel 33 is fixed by the bolts and nuts.

[0033] By setting the support panel 33 as an adjustable structure, the support panel 33 can be adjusted according to the bending degree of the filling pipe 81, thereby making the saddle 3 have a wider range of applications. When the support panel 33 needs to be adjusted, loosen the nut and pull the bolt out of the through hole and the plug hole 331. Then rotate the support panel 33. When the support panel 33 is rotated to the position of the plug hole 331 that meets the requirements, reinsert the bolt into the through hole and the plug hole 331 to fix it. When the support panel 33 rotates, it always rotates around the hinge point of the flip base 35 and the flip bracket 36. The flip bracket 36 serves to limit the rotation trajectory of the support panel 33.

[0034] Furthermore, the flip base 35 is a U-shaped plate structure as a whole and has symmetrically provided axle pin holes on both side walls, and correspondingly provided openings on the flip bracket 36. The openings on the flip bracket 36 are aligned with the axle pin holes, and the flip bracket 362 and the flip base 35 are connected by a pin shaft, so that the flip bracket 36 can rotate around the flip base 35. Similarly, a U-shaped groove is provided at the other end of the flip bracket 36, and axle pin holes are symmetrically provided on the groove wall. A hinge plate is fixedly provided on the side wall of the support panel 33, and an opening is provided on the hinge plate. Similarly, a pin shaft can be used to hinge the hinge plate and the flip bracket 36.

[0035] Furthermore, a plurality of lightening holes 341 are provided on the limiting portion 34 , thereby reducing the weight of the supporting panel 33 and the limiting portion 34 as a whole, thereby making it easier for the crew to flip the supporting panel 33 .

[0036] In some embodiments of the present invention, the filling system further includes a novel tooling and a liquid collecting pan 5. The liquid collecting pan 5 is arranged in the lower area of ​​the filling pipe 81 between the saddle 3 and the bracket 2 before entering the vehicle cabin 61, the lower area of ​​the connecting elbow in the vehicle cabin 61, and the lower area of ​​the filling station 7 on the ship. The novel tooling is arranged on the filling pipe 81 between the bracket 2 of the vehicle cabin 61 and the connecting elbow in the vehicle cabin 61, and on the filling pipe 81 between the connecting elbow in the vehicle cabin 61 and the filling station 7 on the ship. Both the novel tooling and the liquid collecting pan 5 are used to prevent the fuel leaking from the filling pipe 81 from dripping onto the deck, thereby protecting the deck from being damaged by the leaking fuel.

[0037] Specifically, before entering the vehicle cabin 61, since the height of the filling pipe 81 at the saddle 3 and the bracket 2 is greater than the height of the filling pipe 81 between the two, when fuel leaks from the filling pipe 81, the fuel will flow to the lowest point along the filling pipe 81. Therefore, a liquid collecting pan 5 is provided in the area below the filling pipe 81 between the saddle 3 and the bracket 2 to collect the leaked fuel and prevent it from falling on the deck. After entering the vehicle cabin 61, fuel leakage is prone to occur at the connecting elbow of the vehicle cabin 61, so a liquid collecting pan 5 is also provided in the area below the connecting elbow in the vehicle cabin 61. The area of ​​the shipboard filling station 7 is relatively small, so a liquid collecting pan 5 can be provided in the entire area of ​​the shipboard filling station 7 to collect and process the leaked fuel. A new tooling is provided on the remaining filling pipes 81 to collect the leaked fuel.

[0038] Optionally, the housing is configured to be cylindrical.

[0039] Furthermore, the novel tooling includes a shell, a shell support 42, a carrying platform 43 and a platform support 44. The shell is used to surround the filling pipe 81. The shell support 42 is arranged at the bottom of the shell to support the shell. The carrying platform 43 is arranged inside the shell to set up the filling pipe 81. The platform support 44 is arranged at the bottom of the carrying platform 43 to support the carrying platform 43. The shell includes an upper shell 411 and a lower shell 412, one end of the upper shell 411 and the lower shell 412 are hinged by a hinge 413, and the other end is fixedly connected by bolts.

[0040] Specifically, the new tooling opens the upper shell 411 and the lower shell 412 by removing the bolts, so that the outer shell can be easily enclosed on the filling pipe 81. When the filling pipe 81 leaks, the leaked fuel will be in the outer shell, so it will not drip on the deck, thereby protecting the deck. After opening the outer shell, the filling pipe 81 can be set up on the carrying platform 43, which is relatively convenient to operate. When in use, the new tooling is placed on the deck and is stably placed by the outer shell support 42. When the buffer room 62, the airlock room 63 and the bracket 2 at the position of the onboard filling station 7 are set to the same height, the filling pipe 81 set up on the bracket 2 at the buffer room 62, the airlock room 63 and the onboard filling station 7 is in a horizontal state. At this time, the new tooling can be placed on the bracket 2.

[0041] Optionally, the new tooling is made of stainless steel SUS316. The new tooling is spliced, and the length can be customized according to the actual ship requirements. In addition, the shell is wrapped with an insulating layer.

[0042] In some embodiments of the present invention, the filling system further includes a water curtain pipe system. The water curtain pipe system includes a water source and a water curtain pipe. The water curtain pipe is connected to the water source, and the water curtain pipe is arranged outside the ship's side, and the water curtain pipe is arranged parallel to and spaced from the ship's side wall. The water curtain pipe can spray a water curtain toward the ship's side.

[0043] Specifically, a plurality of fixed rods perpendicular to the ship's side are arranged at intervals along the ship's side at the ship's filling station 7, and water curtain pipes are arranged on the fixed rods. The water curtain pipe is arranged parallel to the ship's side wall and is spaced apart from the ship's side wall. When clean water is transported to the water curtain pipe by the water source, the water curtain pipe will spray water mist toward the ship's side. By setting the water curtain pipe, when the filling pipe 81 on the railing of the ship's filling station 7 leaks, the water curtain sprayed by the water curtain pipe can dilute the leaked fuel to prevent the fuel from polluting the water area.

[0044] In some embodiments of the present invention, the filling system further includes a quick connector 82 (i.e., QCDC). The filling pipe 81 includes a gas filling pipe and a liquid filling pipe, which are arranged horizontally side by side. The liquid filling pipe is connected to the interface of the onboard filling station 7 through the QCDC to achieve the purpose of quick connection or disconnection.

[0045] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
