Description

Technical Field

[0001] The present invention relates to the technical field of ship system design, in particular to a ship filling system. Background Art

[0002] With the promotion and development of green ecology in the shipping industry, new energy fuels are gradually coming into the spotlight. LPG and other gaseous fuels, as clean energy sources, can effectively reduce carbon emissions and air pollution from ships, while also reducing noise and vibration, and improving ship comfort and safety. Furthermore, using LPG as fuel can significantly reduce fuel costs. Due to its high energy density, ships can carry more fuel, reducing refueling times and improving operational efficiency. Therefore, the development prospects of dual-fuel vessels are very promising.

[0024] like Figure 1-Figure 3As shown, an embodiment of the present invention provides a ship refueling system, comprising an onshore refueling station 1, a refueling pipe 81, a bracket 2, a connecting elbow, a buffer room 62, an airlock 63, and an onboard refueling station 7. The refueling pipe 81 connects the onshore refueling station 1 with the onboard refueling station 7. The refueling pipe 81 passes from the onshore refueling station 1 through the vehicle compartment 61, the buffer room 62, and the airlock 63, entering the onboard refueling station 7. The buffer room 62 balances the pressure difference between the inside and outside of the onboard refueling station 7, thereby reducing the impact of pressure fluctuations on the onboard refueling station 7 and related equipment. The airlock 63 isolates different areas and controls airflow, thereby reducing the risk of untreated outside air entering critical areas. The connecting elbow is located at the bend of the refueling pipe 81. The bracket 2 is located at the step where the refueling pipe 81 enters the vehicle compartment 61, the step where the vehicle compartment 61 enters the buffer room 62, the step where the buffer room 62 enters the airlock 63, and the step where the airlock 63 enters the onboard refueling station 7. The bracket 2 is used to lift the filling pipe 81 so that it can pass through each step smoothly. By setting up the above filling system, the stern of the ship can be 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 fixed along one side wall of the vehicle cabin 61. When the filling pipe 81 extends to the direction where the vehicle cabin 61 is flush with the onboard filling station 7, it needs to turn before it can 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 from the vehicle compartment 61 toward the shipboard refueling station 7, enters the buffer room 62, a relatively high step is provided at the entrance to the buffer room 62. Therefore, a bracket 2 is also provided at the step where the vehicle compartment 61 enters the buffer room 62. Similarly, a bracket 2 is also provided at the step where the buffer room 62 enters the airlock 63, and at the step where the airlock 63 enters the shipboard refueling station 7. This ensures that the filling pipe 81 can smoothly enter the buffer room 62, the airlock 63, and the shipboard refueling station 7. After entering the shipboard refueling station 7, the filling pipe 81 gradually rises along the side railing to connect with the port of the shipboard refueling station 7. Therefore, a bend is required at both the point where the filling pipe 81 enters the shipboard refueling station 7 from the airlock 63 and extends toward the side railing, and at the point where the filling pipe 81 is mounted on the side railing and extends toward the port of the shipboard refueling station 7. Accordingly, a connecting elbow is also provided at each bend. The filling pipe 81 may be provided with two turning points when it is laid on the side railing and extends toward the interface of the filling station 7 on board the ship.

[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 disposed on the deck near the location where the filling pipe 81 is mounted on the ship's 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. After the filling pipe 81 enters the onboard filling station 7, a saddle 3 is provided on the deck along the interface 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 limiting portion 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 has an overall upwardly convex curved surface structure. The filling pipe 81 can be placed on the support panel 33 and extend along the curved surface of the support panel 33, thereby supporting the filling pipe 81. The limiting portion 34 is provided on both sides of the support panel 33 to limit the position of the filling pipe 81 and prevent the filling pipe 81 from falling off the saddle 3.

[0029] Furthermore, diagonal braces 37 are provided on the side walls of the seat body 32 to enhance the stability of the seat body 32 .

[0030] Furthermore, the limiting portion 34 includes two limiting plates, which are respectively fixed on both sides of the supporting panel 33 .

[0031] Furthermore, the seat body 32 includes a vertical rod 321 and a horizontal rod 322. The vertical rod 321 is vertically mounted on the base 31, while the horizontal rod 322 is horizontally mounted on the central sidewall of the vertical rod 321. The saddle 3 also includes a tilting base 35 and a tilting bracket 36. The tilting base 35 is fixedly mounted on the horizontal rod 322. One end of the tilting bracket 36 is rotatably connected to the tilting base 35, and the other end is hinged to the support panel 33, allowing the support panel 33 to rotate about the tilting base 35.

[0032] The saddle 3 also includes bolts and nuts. The saddle body 32 is provided with through-holes, and the support panel 33 is provided with a plurality of insertion holes 331 along the rotational trajectory of the support panel 33. When the support panel 33 is rotated until the insertion holes 331 and the through-holes are aligned on the same axis, the bolts can be inserted into the through-holes and insertion holes 331, thereby securing the support panel 33 via the bolts and nuts.

[0033] By configuring the support panel 33 as an adjustable structure, the support panel 33 can be adjusted according to the degree of curvature of the filling pipe 81, thereby expanding the applicability of the saddle 3. When the support panel 33 needs to be adjusted, the nut is loosened and the bolt is withdrawn from the through-hole and the insertion hole 331. The support panel 33 is then rotated. When the support panel 33 is rotated to the required insertion hole 331 position, the bolt is reinserted into the through-hole and the insertion hole 331 to secure it. As the support panel 33 rotates, it always rotates around the hinge point between 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 an overall U-shaped plate structure with symmetrical pin holes formed on both side walls. Corresponding holes are formed on the flip bracket 36. By aligning the holes in the flip bracket 36 with the pin holes and connecting the flip bracket 362 to the flip base 35 with a pin, the flip bracket 36 can be rotated about the flip base 35. Similarly, the other end of the flip bracket 36 has a U-shaped groove with symmetrical pin holes formed on the groove walls. A hinge plate is fixed to the side wall of the support panel 33, with holes formed on the hinge plate. Similarly, a pin can be used to hinge the hinge plate to 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 refueling system further includes a novel fixture and a liquid collection tray 5. The liquid collection tray 5 is located below the refueling pipe 81 between the saddle 3 and the bracket 2 before entering the vehicle compartment 61, below the connecting elbow inside the vehicle compartment 61, and below the onboard refueling station 7. The novel fixture is located on the refueling pipe 81 between the bracket 2 in the vehicle compartment 61 and the connecting elbow inside the vehicle compartment 61, and between the connecting elbow inside the vehicle compartment 61 and the onboard refueling station 7. Both the novel fixture and the liquid collection tray 5 are used to prevent fuel leaking from the refueling pipe 81 from dripping onto the deck, thereby protecting the deck from damage caused 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 collection tray 5 is set 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. Therefore, a liquid collection tray 5 is also set in the area below the connecting elbow in the vehicle cabin 61. The area of ​​the onboard filling station 7 is relatively small, so a liquid collection tray 5 can be set in the entire area of ​​the onboard filling station 7 to collect and process the leaked fuel. New tooling is set on the remaining filling pipes 81 to collect the leaked fuel.

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

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

[0040] Specifically, the new tooling is opened by removing the bolts to open the upper shell 411 and the lower shell 412, thereby facilitating the outer shell to surround the filling pipe 81. When the filling pipe 81 leaks, the leaked fuel will be in the outer shell and will not drip onto 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 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 SUS316 stainless steel. The new tooling is spliced ​​together, and the length can be customized to meet the needs of the actual vessel. Additionally, the outer 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 is disposed outside the ship's side, parallel to and spaced apart from the ship's sidewall. The water curtain pipe can spray a water curtain toward the ship's side.

[0043] Specifically, at the ship's refueling station 7, a plurality of fixed rods are spaced perpendicular to the ship's side, and water curtain pipes are mounted on these rods. The water curtain pipes are arranged parallel to and spaced from the ship's sidewalls. When clean water is supplied to the water curtain pipes from a water source, they spray water mist toward the ship's side. This ensures that if a refueling pipe 81 on the railing leading out of the refueling station 7 leaks, the water curtain sprayed from the water curtain pipes can dilute the leaking fuel, preventing fuel contamination of the water surface.

[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-phase filling pipe and a liquid-phase filling pipe, which are arranged horizontally side by side. The liquid-phase filling pipe is connected to the interface of the onboard filling station 7 via the QCDC to achieve quick connection and 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 skilled in 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 one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
