Description

Technical Field

[0001] This utility model relates to the field of marine diesel engine equipment, and in particular to a large-capacity oil pan suitable for marine environments. Background Technology

[0002] In the field of marine equipment such as ships and offshore platforms, diesel engines are the core power source, and their operational stability directly determines the reliability and safety of the equipment. As a key component of the diesel engine lubrication system, the oil pan mainly undertakes the core functions of storing lubricating oil, dissipating heat, and providing a stable oil supply to the oil pump. Its structural design and performance adaptability must be fully matched to the special requirements of the operating environment. Unlike land-based operating conditions, diesel engines in marine environments face complex attitude changes such as pitching and rolling over over extended periods. Under typical sea conditions, diesel engines may experience extreme conditions such as a 15° forward pitch, a 30° backward pitch, and a 22.5° lateral roll. This poses a severe challenge to the oil pan's ability to prevent oil sloshing and maintain a stable oil supply. Most existing mainstream diesel engine oil pans are designed for stable land-based operating conditions, resulting in several adaptability defects: First, they lack specific anti-sloshing designs. In turbulent sea conditions, the lubricating oil in the oil pan is prone to violent sloshing, which in extreme cases can expose the oil pump suction port, causing an interruption in the lubrication system's oil supply and leading to wear or even failure of critical engine components. Second, the lubricating oil easily mixes with air during sloshing, generating a large amount of foam and bubbles. If these bubbles enter the lubrication circuit, they will damage the oil film integrity, exacerbating frictional wear on moving parts such as pistons and crankshafts, while also affecting the lubricating oil's heat dissipation efficiency. Third, existing oil pans generally have insufficient capacity to meet the long-term continuous operation requirements of marine equipment, often requiring operation periods of less than 50 hours. Replenishing lubricating oil during the cycle and frequent shutdowns for maintenance not only reduce operational efficiency but also increase the difficulty of maintenance in the marine environment; fourth, some oil pans are made of ordinary steel, which has weak resistance to seawater corrosion and is prone to rust in the high humidity and high salt spray marine environment for a long time, shortening its service life; in addition, the traditional oil pan design does not fully take into account the need for lightweighting, and the heavier structure will increase the overall load of the ship, which is not in line with the development trend of energy conservation and consumption reduction in marine equipment. As marine equipment develops towards larger size and longer endurance, the requirements for the reliability, ease of maintenance, and lightweight design of diesel engines are increasing. There is an urgent need for an oil pan design that can adapt to complex sea conditions, has a large oil storage capacity, can eliminate lubricating oil bubbles, is resistant to seawater corrosion, and is lightweight. This is to solve the technical pain points of existing land-based oil pans in marine environments, such as poor oil stabilization, frequent maintenance, easy corrosion, and heavy weight, and to ensure the long-term stable operation of diesel engines in sea conditions. Utility Model Content

[0003] The technical problem this invention aims to solve is to provide a large-capacity oil sump suitable for marine environments. It addresses the issues arising from the violent sloshing of lubricating oil under rolling and pitching conditions in marine environments, which can lead to interruptions in oil pump supply, damage to lubrication and heat dissipation due to foam and air bubbles generated by the sloshing, and frequent maintenance due to insufficient oil storage capacity.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a large-capacity oil sump suitable for marine environments, including an oil sump, which is a sunken flat oil sump, the opening width of the oil sump is smaller than the bottom width of the sump, the opening is surrounded by four straight flat plates, a lower baffle is provided at the bottom of the opening, an upper baffle is provided in the middle of the opening, and a ring of oil sump sealing gasket is provided at the top of the opening.

[0005] A further improvement of this utility model is that the lower baffle is a trapezoidal structure that extends upwards, and the top plate has several through holes.

[0006] A further improvement of the present invention is that: a sub-plate is provided in the middle of the two flat plates at the opening, the upper baffle is trapezoidal and extends downward, and there are horizontally extending side plates on both sides of the top of the upper baffle. The two side plates are respectively mounted and fixed on the upper edge of the two sub-plates.

[0007] A further improvement of this utility model is that: the flat plate supplied from the bottom of the upper baffle is provided with several through holes, and the length of the upper baffle is less than the length of the lower baffle.

[0008] A further improvement of this utility model is that: a number of vertically upward connecting plates are provided on the flat plate supplied from the bottom of the upper baffle.

[0009] A further improvement to the technical solution of this utility model is that the oil pan is made of ZL101 material.

[0010] The technological advancements achieved by this invention, due to the adoption of the aforementioned technical solutions, are as follows: By setting two arched baffles with through holes, the violent sloshing of lubricating oil during sea conditions is effectively suppressed, preventing the oil pump suction port from being exposed. Simultaneously, the baffles generated by the sloshing action break up any foam or bubbles, ensuring stable oil supply and oil film integrity in the lubrication system, and improving heat dissipation efficiency. By employing a sunken, flat-bottomed oil sump structure with a 100L capacity, the system meets the requirement of no lubrication replenishment within a 50-hour maintenance cycle for the diesel engine, while controlling the overall height of the unit, reducing downtime for maintenance in marine environments and improving operational efficiency. The oil sump is cast from ZL101 aluminum, achieving a lightweight design that reduces the overall weight of the vessel to meet energy-saving requirements, while also possessing strong resistance to seawater corrosion, resisting the corrosive effects of high salt spray and high humidity environments, and extending its service life.

[0012] Among them, 1. oil pan, 2. lower baffle, 3. upper baffle, and 4. oil pan sealing gasket. Detailed Implementation

[0013] The present invention will be further described in detail below with reference to embodiments: like Figure 1 The diagram shows a structural schematic of a large-capacity oil sump suitable for marine environments, including an oil sump 1, as shown. Figure 4 As shown, the oil pan 1 is a sunken flat oil pan, which can be made into various shapes depending on the specific situation. However, the main shape is a long rectangular flat oil pan, which can greatly increase the capacity. With a capacity of 100L, it can meet the requirement of not needing to replenish lubricating oil within a 50-hour maintenance cycle. At the same time, the opening width of the oil pan 1 is smaller than the bottom width of the pan, further ensuring that oil does not overflow. Specifically, the opening is surrounded by four vertical flat plates. At the bottom of the opening of the oil pan 1, i.e., at the bottom of the flat plates, there is a lower baffle 2. The lower baffle 2 is as follows... Figure 3As shown, the upper baffle 3 is a trapezoidal structure that extends upwards. The top plate has several through holes to effectively eliminate foam generated by the lubricating oil during rough seas. Simultaneously, there are attached sub-plates at the center of the two plates on either side of the opening. These sub-plates have a certain thickness and extend upwards from the top plate. The upper baffle 3 is trapezoidal in shape and extends downwards. Horizontally extending side plates are located on both sides of the top of the upper baffle 3, and these side plates are respectively attached and fixed to the upper edges of the two sub-plates. The bottom plate of the upper baffle 3 has several through holes, and its length is shorter than that of the lower baffle 2. This further eliminates foam while the shorter length of the upper baffle 3 does not affect the oil return speed and prevents insufficient oil volume at the bottom of the oil pan. Several vertically upward connecting plates are installed on the bottom plate of the upper baffle 3. These connecting plates allow connection to relevant equipment located on top of the oil pan 1, further securing the upper baffle 3. A ring of oil pan sealing gasket 4 is installed at the top of the opening of the oil pan 1. Relevant equipment is installed above the sealing gasket to seal the opening. The oil pan 1 is made entirely of ZL101 material, which is lighter while ensuring corrosion resistance.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
