Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, specifically to an oil and gas recovery and purification device for marine fuel refueling. Background Technology

[0002] With the increasing popularity of domestic ship refueling operations, the oil and gas volatilized during the refueling process poses problems such as exhaust emissions and fuel loss. Oil and gas recovery and purification have become an essential supporting component of ship refueling operations. Traditional oil and gas recovery equipment is mostly multi-unit, split-type large-scale units, occupying a large area and suitable for large port refueling sites. For the use scenarios of small inland river refueling barges and floating refueling vessels with compact deck space and small oil and gas processing flow rates per berth, integrated small-scale oil and gas recovery and purification devices have emerged. This equipment integrates oil and gas filtration, suction and conveying, condensation recovery, adsorption purification, oil storage, and control components into a single skid-mounted unit. The overall size is adapted to the ship's deck layout conditions, and it is pre-assembled at the factory, allowing for complete hoisting and installation on the ship. It can fully complete the entire process of oil and gas collection, fuel recovery, and exhaust gas purification during ship refueling, and is widely used in various small and medium-sized floating refueling facilities.

[0003] The existing shipborne small integrated oil and gas recovery and purification device has a base made of thick steel fully welded together. The structure is bulky and heavy. The whole unit is integrated and cannot be disassembled, which makes the whole hoisting and relocation operations very difficult. At the same time, the base is only 50-100mm off the ground, and the operating space at the bottom is narrow. Deck water, oil and mud can easily accumulate in the base sandwich and dead corners of the profile, which is difficult to clean. Long-term accumulation will accelerate the internal corrosion of the steel frame. In addition, simply raising the base will raise the center of gravity of the whole unit, which will exacerbate the swaying and instability problem under the ship's rolling conditions. The structural design has obvious contradictions and defects.

[0004] Therefore, a solution is needed. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-6 The present invention provides a technical solution to achieve this: it includes an integrated recycling and purification device 1 and a support mechanism 2, with the support mechanism 2 located at the bottom of the integrated recycling and purification device 1.

[0022] The support mechanism 2 includes a base 21, a mounting groove 22, a shock-absorbing pad 23, a screw hole 1 24, a mounting plate 1 25, a screw hole 26, a reinforcing plate 27, a limiting plate 28, a positive magnetic plate 29, a support strip 210, a negative magnetic plate 211, an outer support column 212, an inner support column 213, a mounting plate 214, a screw hole 3 215, an outer sealing plate 216, a screw hole 4 217, an inner sealing plate 218, a screw hole 5 219, a screw hole 6 220, a ladder support plate 221, a slot 222, a screw hole 7 223, a ladder plate 224, and a locking strip 225. The mounting groove 22 is recessed at the top of the base 21 to absorb shock. Pad 23 is placed inside mounting groove 22. Screw holes 24 are placed on the left and right ends of the top of base 21. Mounting plate 25 is placed on the left and right ends of integrated recycling and purification device 1. Screw holes 26 are placed on mounting plate 25 corresponding to the positions of screw holes 24. Reinforcing plate 27 is placed obliquely on mounting plate 25. Limiting plate 28 is placed on the four sides of base 21. Positive magnetic plate 29 is placed at the inner end of each limiting plate 28. Support bar 210 is inserted into each limiting plate 28. Negative magnetic plate 211 is placed on each support bar 210 corresponding to the position of each positive magnetic plate 29. The outer support columns 212 are located at the four corners of the bottom of the base 21. The inner support columns 213 are arranged opposite each other between every two outer support columns 212. The mounting plate 214 is located at the bottom between each adjacent outer support column 212 and inner support column 213 and at the bottom between every two outer support columns 212. The screw holes 215 are evenly distributed on each mounting plate 214. The outer sealing plate 216 is located on the inner side of each mounting plate 214. The screw holes 217 are evenly distributed on the opposite surfaces of every two inner support columns 213. The inner sealing plate 218 is located on every two inner support columns 213. On the opposite surface of column 213, screw hole five 219 is set on each inner sealing plate 218 corresponding to the position of each screw hole four 217. Screw hole six 220 is set opposite to each other on the front end of base 21. Ladder support plate 221 is set at the front end of screw hole six 220 corresponding to the position of the two inner support columns 213 at the front end. Slot 222 is equidistantly set on each support plate 221. Screw hole seven 223 is set at the rear end of slot 222 at the top corresponding to the position of each screw hole six 220. Ladder plate 224 is set on each of the two slots 222 on the left and right. Slot strip 225 is set opposite to each left and right end of ladder plate 224.

[0023] In detail, the base 21 has a rectangular structure, the mounting plate 25 has an L-shaped structure, the mounting plate 25 and the integrated recycling and purification device 1 are integrally formed, and the reinforcing plate 27 and the mounting plate 25 are integrally formed.

[0024] The limiting plate 28 has a frame structure that is enclosed on all four sides and hollow. The limiting plate 28 is located at both ends of each side of the base 21 along its length. The limiting plate 28 and the base 21 are integrally formed. The two ends of the support strip 210 have obtuse angle structures.

[0025] Both the outer support column 212 and the inner support column 213 are rectangular in shape and have the same specifications. The mounting plate 214 is a flat rectangular in shape. The support column 212, the inner support column 213, the mounting plate 214 and the base 21 are integrally formed.

[0026] The height of the outer sealing plate 216 is the same as the height of the outer support column 212. Both the inner sealing plate 218 and the outer sealing plate 216 are cuboid structures and have the same height.

[0027] The support plate 221 has an inclined structure, the bottom of each slot 222 has a horizontal structure, the ladder plate 224 has a cuboid structure, and the locking strip 225 is located on the rear side of each ladder plate 224. The ladder plate 224 and the locking strip 225 are integrally formed.

[0028] Solution Analysis: 1. The detachable and modular structure significantly reduces the load during hoisting and transportation, solving the problem of the bulky and heavy traditional integrated base. The support mechanism 2 of this device is assembled with modular, detachable components and a base 21, eliminating the need for the traditional, fully welded, and non-separable heavy steel frame structure. The inclined support bar 210 is quickly assembled and disassembled using the magnetic attraction between the positive and negative magnetic plates 29 and 211. The ladder plate 224 in the maintenance ladder structure can be easily installed and removed from the slot 222 of the ladder support plate 221 via the clip 225. The inner sealing plate 218 is detachably mounted to the inner support column 213 via screw holes 219. During equipment transfer and hoisting onto a ship, the support bar 210, ladder plate 224, inner sealing plate 218, and other accessories can be individually disassembled and separated. Only the base 21, the integrated components, and the main body of the integrated recycling and purification device 1 need to be transported, effectively reducing the overall weight during transport and lowering the load burden on small floating refueling vessels, making it suitable for the operating conditions of small lifting equipment on inland waterway pontoons.

[0029] 2. Raise the base off the ground to allow space for cleaning at the bottom and mitigate the problem of steel frame corrosion. The base 21 features an integrally formed outer support column 212 and inner support column 213 at its bottom. The height of these support columns elevates the overall ground clearance of the base 21, completely overcoming the traditional limitations of a low base with a height of only 50-100mm. This creates a spacious and open area beneath the base 21. Water, oil, and silt generated on the deck can flow directly between the two inner sealing plates 218 at the bottom, preventing accumulation in the base's interlayer and dead corners of the profiles. This significantly reduces the long-term adhesion and corrosion of the steel frame by oil and silt, extending the service life of the entire support mechanism 2. The outer sealing plate 216 is welded to form a protective layer on the outside of the support column, preventing splashed oil and seawater from eroding the outer wall of the support column and further enhancing rust prevention.

[0030] 3. The magnetic bracing structure balances the raised center of gravity caused by the elevated base, improving stability under bumpy conditions. The base 21 has limiting plates 28 on all four sides, with positive magnetic plates 29 installed inside the limiting plates 28. The ends of the support bars 210 are fitted with negative magnetic plates 211. The support bars 210 are obliquely inserted into the limiting plates 28 and continuously fixed by the magnetic attraction of the positive and negative magnetic plates. Multiple obliquely arranged support bars 210 provide multi-directional limiting and reinforcement to the base 21 from the side, offsetting the upward shift of the overall center of gravity after the base 21 is raised. When the ship is sailing or during refueling operations, the magnetically fixed support bars 210 can share the lateral impact force, limiting the horizontal displacement of the base 21 and preventing the integrated recycling and purification device 1 from shaking or becoming unstable. This resolves the design contradiction between simply raising the base and ensuring equipment stability.

[0031] IV. Integrated maintenance ladder structure facilitates staff access for maintenance of main equipment. The base 21 has an inclined ladder support plate 221 mounted on its front end via screw holes 220 and 223. The ladder support plate 221 has evenly spaced slots 222. The ladder plate 224 has integrally formed locking strips 225 at both ends. These strips engage with the slots 222 to limit the ladder plate 224's position. Multiple ladder plates 224 can be combined to form a complete maintenance ladder. Workers can climb the ladder to directly inspect the top integrated recovery and purification device 1, perform operations such as filling pipeline maintenance, oil and gas filter replacement, and electrical control component debugging. The ladder plates 224 can be individually disassembled and reassembled, allowing for adjustments to the number of ladder plates 224 based on working height requirements. This eliminates the need for additional equipment or temporary scaffolding, making it suitable for working environments with limited deck space and little room for storage.

[0032] V. Shock-absorbing and buffering + stable locking structure reduces the damage of ship vibration to the main purification engine. The base 21 has a recessed mounting groove 22 at its top, and a shock-absorbing pad 23 is laid inside the mounting groove 22. The integrated recycling and purification device 1 is placed on top of the shock-absorbing pad 23. L-shaped mounting plates 25 are fitted on both sides of the device, with screw holes 26 on each plate. A corresponding screw hole 24 is provided on the top of the base 21. Fasteners pass through screw holes 24 and 26 to lock the integrated recycling and purification device 1 onto the base 21. When continuous vibrations from the ship are transmitted to the base 21, the shock-absorbing pad 23 absorbs the impact vibrations, reducing the transmission of vibrations to the integrated recycling and purification device 1, causing condensation and adsorption of precision components, and preventing pipe loosening and instrument damage. The L-shaped mounting plate 25, combined with the inclined reinforcing plate 27, forms a triangular reinforcement structure, improving the structural strength of the connection between the main engine and the base 21, making it less prone to cracking under long-term turbulent conditions.

[0033] VI. Standardized installation structure, adaptable to various small floating bunker deck bases The base 21 has multiple sets of mounting plates 214 at its bottom. The mounting plates 214 are evenly provided with screw holes 215. Workers can use the screw holes 215 to lock and fix the entire base 21 onto the deck support base of different specifications of ships. The outer support column 212 and the inner support column 213 are of the same specification. The height of the outer sealing plate 216 and the inner sealing plate 218 matches the support column. The dimensions of the entire support mechanism 2 are standardized, eliminating the need to customize the base separately for different pontoons, thus reducing the equipment production and on-site installation costs.

[0034] Working principle: The base 21 is installed on the existing ship's load-bearing hull via screw hole three 215. The outer sealing plate 216 is connected to the outer support column 212, inner support column 213, mounting plate two 214, and base 21 by welding. The inner sealing plate 218 is installed on the inner support column 213 via screw hole five 219. The ladder support plate 221 is installed on the front end of the base 21 via screw hole seven 223. The ladder plate 224 is directly installed on the slot 222 and limited by the locking strip 225. The ladder plate 224 can be installed and removed at any time. Several locking strips 225 form a ladder that allows workers to walk up to operate and maintain the integrated recycling and purification device 1. The integrated recycling and purification device 1 can be fixed to the base 21 via screw hole two 26. Each support strip 210 can be continuously fixed by the attraction of the positive magnetic plate 29 and the negative magnetic plate 211, thereby strengthening the overall limit and enhancing the overall stability.

[0035] Technical effects of implementing this solution: This solution addresses multiple industry pain points through its modular, detachable support structure, combined with heightened support columns and magnetic braces, integrated detachable maintenance ladder, and built-in shock-absorbing locking structure. These issues include the bulkiness and difficulty in transporting traditional shipborne oil and gas recovery bases, the ease with which dirt and rust accumulate at the bottom, instability of the center of gravity after raising the base, and the lack of maintenance and operation space on the deck. The overall structure is suitable for the narrow deck conditions of small floating refueling vessels in inland waterways, taking into account the convenience of transport, rust prevention and durability, stability during turbulence, and ease of daily equipment maintenance, demonstrating outstanding practical value.

[0036] The present invention comprises: 1-integrated recycling and purification device; 2-support mechanism; 21-base; 22-mounting groove; 23-shock-absorbing pad; 24-screw hole one; 25-mounting plate one; 26-screw hole two; 27-reinforcing plate; 28-limiting plate; 29-positive magnetic plate; 210-support strip; 211-negative magnetic plate; 212-outer support column; 213-inner support column; 214-mounting plate two; 215-screw hole three; 216-outer sealing plate; 217-screw hole four; 218-inner sealing plate; 219-screw hole five; 220-screw hole six; 221-ladder support plate; 222-slot; 223-screw hole seven; 224-ladder plate; 225-slot strip. These components are all general standard parts or parts that are easy to understand by those skilled in the art. The components, structures, and principles of which are known to personnel, can be understood by those skilled in the art through technical manuals or conventional experimental methods. The problem this invention solves is that existing shipborne small integrated oil and gas recovery and purification devices use a base made entirely of thick, welded steel, resulting in a bulky and heavy structure. The integrated, non-separable design makes hoisting and relocation operations extremely difficult. Furthermore, the base's ground clearance is only 50-100mm, leaving limited operating space at the bottom. Deck water, oil, and silt easily accumulate in the base's layers and corners, making cleaning difficult and accelerating corrosion of the steel frame over time. Simply raising the base also raises the overall center of gravity, exacerbating instability and swaying under ship rolling conditions. The structural design contains significant contradictions and defects. This invention specifically addresses these shortcomings of traditional oil and gas recovery bases, adapting to the confined decks of small inland waterway floating refueling vessels. It offers advantages such as convenient transport, corrosion resistance, durability, stable operation, and easy maintenance, making it highly practical for engineering applications.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
