Description

Technical Field

[0001] The utility model relates to the technical field of water refueling, in particular to a water refueling station. Background Art

[0002] Existing water gas stations are easily corroded by factors such as moisture and salt during long-term use due to their storage environment in aquatic environments, which can cause leakage in pipelines or equipment that transport oil. Once a leak occurs, especially a minor leak, it is difficult for operators to detect the leak location in time and carry out repairs, resulting in delayed remedial repairs.

[0003] The prior art includes technologies that use various sensors to detect pipeline oil leaks, such as a sensor fixing device for non-destructive testing of oil pipelines with application number "202122256681.6", and a distributed optical fiber sensor oil pipeline leakage detection device based on intelligent interlayer with application number "201420027429.5". The above patented technologies all use sensors to detect oil pipelines. However, when the prior art detects pipeline oil leakage, it is difficult to quickly determine the leakage point, and it is difficult to repair and remedy the leakage in time after it occurs, resulting in oil penetration and pollution.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs a water refueling station to solve the above technical problems. Utility Model Content

The plurality of supporting walls cooperate with the inner wall and the outer wall to form a plurality of protection zones of equal area, and the protection zones are filled with inert protective gas.

[0009] A guardrail is installed at the edge of the main body of the floating platform on water, and a docking guide light is fixedly installed on the guardrail.

[0010] The isolation wall is divided into an axial isolation wall and an annular isolation wall. The axial isolation wall is fixedly installed on the outer surface of the inner tube. The axial isolation wall passes through the annular isolation wall. The surface of the axial isolation wall is embedded with N-pole magnets at equal intervals. The surface of the annular isolation wall is embedded with S-pole magnets that match the magnets on the surface of the axial isolation wall.

[0030] The present disclosure aims to solve the existing problem of difficulty in timely detecting leaks and conducting repairs. In view of this, the present disclosure provides a floating gas station, comprising a floating platform body 1, a deck 11 being provided on the floating platform body 1, a crew cabin 12 being fixedly mounted above the floating platform body 1 for accommodation, and a supermarket being located within the crew cabin 12. A refueling machine 2 is fixedly mounted on the floating platform body 1, a double-layer oil tank 3 being fixedly mounted within the floating platform body 1, the double-layer oil tank 3 being connected to the refueling machine 2 via an oil pipeline, and the refueling machine 2 refueling through a double-layer leak-proof pipe 4. The double-layer leak-proof pipe 4 is divided into an inner pipe 41 and an outer pipe 42, the space between the inner pipe 41 and the outer pipe 42 being filled with an inert protective gas, a plurality of partition walls being mounted on the outer surface of the inner pipe 41, and a plurality of sensors 5 being fixedly mounted on the outer surface of the inner pipe 41, wherein the sensors 5 are gas pressure sensors 5, and the gas pressure sensors 5 are alternately mounted with the partition walls. The isolation wall is divided into an axial isolation wall 43 and an annular isolation wall 44. The axial isolation wall 43 is fixedly mounted on the outer surface of the inner tube 41. The axial isolation wall 43 passes through the annular isolation wall 44. The surface of the axial isolation wall 43 is embedded with N-pole magnets 45 at equal intervals. The surface of the annular isolation wall 44 is embedded with S-pole magnets 46 that match the magnets on the surface of the axial isolation wall 43. The annular isolation wall 44 is slidably mounted on the outer surface of the inner tube 41 and can move axially using the axial isolation wall 43 as a guide rail. The annular isolation wall 44 can be fixed by the opposite attraction between the N-pole magnet 45 and the S-pole magnet 46. The opposite attraction between the N-pole magnet 45 and the S-pole magnet 46 allows the axial isolation wall 43 and the annular isolation wall 44 to isolate the outer surface of the inner tube 41 to form multiple detection areas of equal area. The outer tube 42 is coaxially sleeved with the inner tube 41 via a partition wall. A repair opening 47 is opened on the outer surface of the outer tube 42. A repair cover plate 48 is fixedly installed in the repair opening 47 by fastening bolts.

[0031] After the ship docks, the operator connects the refueling machine 2 to the oil tank of the ship to be refueled through the double-layer leak-proof pipe 4. After the connection is completed, the operator operates the refueling machine 2 to refuel the ship to be refueled. During the refueling process, the oil leaves the double-layer oil tank 3 through the oil pipeline, and then refuels through the refueling machine 2 and the double-layer leak-proof pipe 4. The double-layer refueling pipe can provide double protection for the oil being transported and circulated through the double-layer design, that is, when the inner pipe 41 for transporting the oil is ruptured and damaged and causes leakage, the outer pipe 42 can also prevent Oil seeps out; and the gas pressure sensor 5 can detect the pressure of the gas filled between the inner tube 41 and the outer tube 42, and then the air tightness of the surface of the inner tube 41 and the outer tube 42 can be detected by the change of the gas pressure between the inner tube 41 and the outer tube 42, thereby preventing the inner tube 41 and the outer tube 42 from being damaged and causing oil leakage. After detecting the leakage point, the personnel open the repair cover 48 and then slide the annular isolation wall to the leakage point for sealing, and then wait for the maintenance personnel to bring tools to repair the inner tube 41.

[0032] The annular isolation wall 44 is fixed by the oppositely charged N-pole magnet 45 and the S-pole magnet 46, thereby dividing the area between the inner tube 41 and the outer tube 42 into a plurality of areas of equal area. When the double-layer leak-proof tube 4 leaks, the gas pressure sensors 5 in different areas can detect the gas pressure in real time. The gas pressure sensor 5 can monitor the gas pressure in real time to quickly determine the leakage area of the double-layer leak-proof tube 4, thereby achieving the effect of quickly determining the leakage location for repair.

[0033] It should be noted that the axial partition wall 43, the annular partition wall 44, the inner tube 41, and the outer tube 42 are all sealed connections in the prior art, and only need to ensure a gas-liquid sealing function. In this embodiment, a floating ring is used for sealing. In addition, a sealing ring or soft packing can also be used for sealing.

[0034] The surface of the annular isolation wall 44 is symmetrically provided with grooves 441, one end of a ejection spring 442 is fixedly installed in the groove 441, and the other end of the ejection spring 442 is fixedly connected to a trapezoidal block 443. The outer tube 42 is a multi-section structure, and the multi-section outer tubes 42 are nested and sealed with each other and are rotatably connected through bearings. The inner surface of the outer tube 42 is symmetrically provided with trapezoidal grooves 421 for accommodating the trapezoidal blocks 443, and the trapezoidal blocks 443 can slide in the trapezoidal grooves 421.

[0035] The trapezoidal block 443 is inserted into the trapezoidal groove 421, thereby realizing circumferential positioning of the outer tube 42 to prevent rotation. It should be noted that the number of the circumferential partition walls 44 is equal to or greater than the number of sections of the outer tube 42, thereby realizing circumferential positioning of multiple sections of the outer tube 42.

[0036] It should be noted that the trapezoidal block 443 is made of rubber material and has sealing performance, so that the trapezoidal block 443 can maintain the sealing performance between the inner tube 41 and the outer tube 42 after being inserted into the trapezoidal groove 421 .

[0037] In the initial state, the N-pole magnet 45 and the S-pole magnet 46 attract each other with opposite polarities to the annular isolation wall 44, so that the annular isolation wall 44 is in the initial position and the trapezoidal block 443 is inserted into the trapezoidal groove 421 to annularly limit and fix the outer tube 42. After the gas pressure sensor 5 detects that the inner tube 41 is damaged and leaks, the operator stops refueling and opens the repair cover 48, then slides the annular isolation wall to the leak point to seal it, and then waits for the maintenance personnel to bring tools to repair the inner tube 41; after the maintenance personnel are in place, they slide the annular isolation wall 44 to the trapezoidal groove 421 of the adjacent section of the outer tube 42, thereby releasing the limit of the outer tube 42 at the current leak, so that the outer tube 42 can be rotated and the repair port 47 is facing the leak, which makes it easier for the maintenance personnel to repair the leak.

[0038] It should be noted that when the leakage point is larger than the area of the annular isolation wall 44 , the operator can slide adjacent annular isolation walls 44 synchronously to the leakage point, thereby sealing the leakage point through the mutual combination of multiple annular isolation walls 44 .

[0039] It should be noted that the oil pipeline connected between the double-layer oil tank 3 and the fuel dispenser 2 has the same structure as the double-layer anti-leakage pipe 4. Therefore, after the oil leaves the double-layer oil tank 3, the air tightness of the oil pipeline itself is tested through the oil pipeline with the same structure as the double-layer anti-leakage pipe 4, thereby preventing the oil pipeline from being damaged and causing oil leakage.

[0040] The double-layer oil tank 3 includes an inner wall 31 and an outer wall 32, and the inner wall 31 and the outer wall 32 are fixedly connected by a plurality of supporting walls 33. The inner wall 31 and the outer wall 32 are arranged at intervals, and the plurality of supporting walls 33 cooperate with the inner wall 31 and the outer wall 32 to form a plurality of detection areas of equal area, and the detection areas are filled with inert protective gas. The surface of the outer wall 32 is provided with a plurality of maintenance ports corresponding to the plurality of detection areas, and the maintenance ports are fixed with maintenance guard plates 34 by bolts.

[0041] It should be noted that the repair opening 47 , the repair cover 48 , the repair opening and the repair guard plate 34 have the same structure and only differ in size.

[0042] The double-layer oil tank 3 can improve the safety and service life of oil storage through its own double-layer structure, thereby better preventing oil leakage; at the same time, the gas pressure sensor 5 in different protection areas between the inner wall 31 and the outer wall 32 can monitor the gas pressure of the inner wall 31 and the outer wall 32 in real time, thereby ensuring the airtightness between the inner wall 31 and the outer wall 32 to prevent leakage during oil storage and improve the safety of oil storage.

[0043] The floating platform body 1 is provided with a guardrail 6 mounted on its edge. Docking indicator lights 61 are fixedly mounted on the guardrail 6 at the fuel dispenser 2 and the double-layered leak-proof pipe 4. When a vessel needs to refuel at night, the docking indicator lights 61 on the guardrail 6 flash, guiding the vessel to bring the fuel tank opening closer to the docking indicator lights 61 when docking. This allows the vessel's fuel tank opening to approach the fuel dispenser 2 and the double-layered leak-proof pipe 4, facilitating refueling operations.

[0044] It should be noted that the outer tube 42 and outer wall 32 are axially divided into two semicircular sections that are then bolted together to achieve a nested installation. A sealing gasket is used between the two semicircular sections of the outer wall 32 to ensure airtightness and prevent leakage. The multi-segment outer tube 42 is installed by splicing each section together and nesting them.

[0045] The inert protective gas is nitrogen, which can avoid chemical reaction with the pipeline to prevent corrosion of the inner wall 31 of the pipeline; at the same time, nitrogen can also reduce the concentration of external combustible air when leaking, thereby suppressing the risk of explosion.

[0046] When a ship needs to refuel, it needs to first approach the floating platform body 1 and then turn off the engine. After the ship docks, the operator connects the refueling machine 2 and the oil tank of the ship to be refueled through the double-layer leak-proof pipe 4. After the connection is completed, the operator operates the refueling machine 2 to refuel the ship to be refueled; during the refueling process, the oil leaves the double-layer oil tank 3 through the oil pipeline, and then enters the oil tank of the ship to be refueled through the refueling machine 2 and the double-layer leak-proof pipe 4 to complete the refueling.

[0047] During refueling or during standby mode, the gas pressure sensors 5 in the double-layer anti-leakage pipe 4, the oil pipeline, and the double-layer oil tank 3 monitor the gas pressure in real time. This allows the gas pressure changes to be used to detect the airtightness of the double-layer anti-leakage pipe 4, the oil pipeline, and the double-layer oil tank 3, thereby preventing damage to the double-layer anti-leakage pipe 4, the oil pipeline, and the double-layer oil tank 3, which could lead to oil leakage. Furthermore, if the double-layer anti-leakage pipe 4, the oil pipeline, or the double-layer oil tank 3 is damaged or leaking, the multiple gas pressure sensors 5 can quickly identify the leak area based on the changes in gas pressure in that area, allowing for rapid identification and repair.

[0048] After determining the leak point, the operator opens the repair cover 48 and then slides the annular partition wall 44 to the leak point to seal it.

[0049] In the initial state, the N-pole magnet 45 and the S-pole magnet 46 attract each other with opposite polarities to the annular isolation wall 44, so that the annular isolation wall 44 is in the initial position and the trapezoidal block 443 is inserted into the trapezoidal groove 421 to annularly limit and fix the outer tube 42. After the gas pressure sensor 5 detects that the inner tube 41 is damaged and leaks, the operator stops refueling and opens the repair cover 48, then slides the annular isolation wall to the leak point to seal it, and then waits for the maintenance personnel to bring tools to repair the inner tube 41; after the maintenance personnel are in place, they slide the annular isolation wall 44 to the trapezoidal groove 421 of the adjacent section of the outer tube 42, thereby releasing the limit of the outer tube 42 at the current leak, so that the outer tube 42 can be rotated and the repair port 47 is facing the leak, which makes it easier for the maintenance personnel to repair the leak.

[0050] If refueling is carried out at night, due to low visibility at night, the ship to be refueled will dock by flashing the docking guide light 61, so that the fuel tank port of the ship to be refueled is close to the refueling machine 2 and the double-layer leak-proof pipe 4 at the docking guide light 61, thereby facilitating the refueling operation.

[0051] After the ship is refueled, the double-layer leak-proof pipe 4 is put away and the bill is settled through the refueling machine 2, thereby completing the refueling work for the ship. The ship can leave after the refueling is completed.

[0052] The description herein is provided to enable one of ordinary skill in the art to implement or use the present disclosure. Various modifications to the present disclosure will be apparent to one of ordinary skill in the art, and the overall principles defined herein may be applied to other variations without departing from the scope of the present disclosure. Therefore, the present disclosure is not limited to the examples and designs described herein, but should be given the widest scope of the principles and novel features disclosed herein.
