Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil storage tanks, in particular to an oil storage tank with an eccentric oil level measuring assembly. BACKGROUND

[0002] The existing oil storage tank usually adopts a cylindrical structure, and an oil level gauge is installed at the center of the end cover of the oil storage tank to monitor the oil quantity in the oil storage tank. The common oil level gauge usually adopts a float rod structure, and the opening angle of the float rod is usually 120°.

[0003] However, this structure has obvious deficiencies: when the float rod falls to the position where the oil level is displayed as 0, there is still a large amount of oil remaining in the oil storage tank, which cannot be accurately reflected; when the float rod rises to the position where the oil level is displayed as 10, there is still a large empty space in the oil storage tank that is not utilized. In other words, the conventional oil level gauge cannot fully cover the oil quantity change range in the oil storage tank, resulting in inaccurate oil quantity indication and affecting the effective utilization rate of the oil storage tank.

[0004] Some existing technologies attempt to improve the measurement accuracy by adjusting the length of the float rod or increasing the rotation angle of the float rod, but this not only increases the size of the device, causing installation inconvenience, but also may cause interference between the float rod and the inner wall of the oil storage tank, reducing the measurement reliability. SUMMARY

[0037] Embodiment one

[0038] An oil storage tank of an eccentric oil level measuring assembly, Figure 1 The overall structure of one embodiment of the present application is shown in the schematic diagram as Figure 1 As shown, it comprises:

[0039] An oil storage tank body 1, an oil cover 2 and an oil level measuring assembly 3;

[0040] The oil storage tank body 1 is a cylindrical structure, the oil cover 2 is arranged at one end of the cylindrical structure of the oil storage tank body 1, and the oil level measuring assembly 3 is arranged on the side of the oil cover 2 facing the inside of the oil storage tank body 1. The oil storage tank body 1 is a cylindrical structure for storing liquid oil products. When in use, the axis of the cylindrical structure is parallel to the horizontal direction. The oil cover 2 is arranged at one end of the cylindrical structure of the oil storage tank body 1, and is used to close the opening of the oil storage tank body 1. The oil cover 2 is reliably connected to the oil storage tank body 1 through a sealing structure to prevent oil leakage and foreign matter from entering the inside of the oil storage tank. The oil cover 2 not only plays a closing role, but also provides a mounting position for the oil level measuring assembly 3. In this embodiment, a sealing ring is arranged between the oil cover 2 and the oil storage tank body 1. The sealing ring is installed between the contact surfaces of the oil cover 2 and the oil storage tank body 1, and is pre-compressed by the tight connection between the oil cover 2 and the oil storage tank body 1, such as bolted flange connection, clamp connection or lock ring connection, to form a reliable sealing interface between the sealing ring and the contact surface, thereby effectively preventing oil leakage and foreign matter from entering the inside of the oil storage tank. The sealing ring is preferably made of an elastic material with oil resistance, high temperature resistance and aging resistance, such as nitrile rubber (NBR), fluororubber (FKM) or silicone rubber (VMQ), to ensure that it can maintain stable sealing performance under long-term contact with oil and temperature changes. In order to enhance the sealing effect, the sealing ring can be designed in the form of an "O" ring, a rectangular ring or a self-tightening sealing ring with a lip, and can be arranged in a sealing groove of the oil cover 2 to prevent the sealing ring from shifting during assembly or operation.

[0041] The oil level measuring component 3 includes a connecting component 310, a float 320, and a float ball 330. The connecting component 310 is located on the side of the oil cap 2 facing the interior of the oil tank body 1, and is used to sense the oil level in the oil tank in real time. One end of the float 320 is movably connected to the connecting component 310, and the other end of the float 320 is connected to the float ball 330. The connecting component 310 is fixedly installed on the side of the oil cap 2 facing the interior of the oil tank body 1, and is used to provide a fulcrum for the float 320 to rotate. One end of the float 320 is movably connected to the connecting component 310 and can rotate around the connection point of the connecting component 310. The other end of the float 320 is connected to the float ball 330, which has good buoyancy and can float up and down with the change of oil level in the oil tank.

[0042] The connecting component 310 is disposed on the horizontal centerline of the oil cap 2, and is also disposed at a position offset from the vertical centerline of the oil cap 2. The connecting component 310 is arranged on the horizontal centerline of the oil cap 2, but its position is offset relative to the vertical centerline, thus exhibiting a certain eccentric structure. This eccentric arrangement allows the float 330 to reach the lowest and highest points of the vertical centerline of the oil cap 2 at the lowest and highest oil levels, respectively, effectively covering the entire measurement range within the oil reservoir.

[0043] Figure 2 A schematic diagram showing the float position when the oil level is at its lowest according to an embodiment of the present invention is shown, as follows. Figure 2 As shown, when the oil level in the oil tank body 1 is at its lowest, the float 330 is in the first position, which is the lowest point of the center line of the oil cap 2 in the vertical direction. Figure 3 A schematic diagram showing the float position at the highest oil level according to an embodiment of the present invention is shown, as follows. Figure 3As shown, when the oil level in the oil tank body 1 is at its highest, the float 330 is in the second position, which is the highest point of the vertical centerline of the oil cap 2. When the oil level in the oil tank body 1 is at its lowest, the float 330 experiences minimal buoyancy and, due to its own weight, is in the first position, which corresponds to the lowest point of the vertical centerline of the oil cap 2. At this time, the float rod 320 is tilted downwards relative to the connecting component 310. As the oil level increases, the buoyancy of the float 330 gradually increases, causing the float rod 320 to rotate around the connecting component 310, thus gradually raising the float 330. When the oil level reaches its highest, the float 330 reaches the second position, which is the highest point of the vertical centerline of the oil cap 2, and the float rod 320 is in a relatively upward-tilted state. The float 330 can move throughout its entire range from the lowest to the highest level within the oil tank, avoiding blind spots in oil level measurement caused by improper placement of the measuring components. Meanwhile, the movable connection between the float 320 and the connecting component 310 ensures the sensitivity and stability of the measurement, enabling real-time reflection of oil level changes. Furthermore, the eccentric oil level measurement component can be combined with a scale display device or a sensor: in a mechanical oil level display embodiment, a pointer structure can be connected to the float 320; when the float 320 rotates around the connecting component 310, the pointer can synchronously move and indicate the corresponding oil level value on the scale; in an electronic oil level measurement embodiment, an angle sensor can be placed at the connecting component 310, and the oil level height can be calculated by detecting the rotation angle of the float 320, and the oil level information can be output to the display terminal through a signal processing module.

[0044] Furthermore, in this embodiment, the connecting component 310 includes a rotating shaft and a fixed base. The float 320 is movably connected to the fixed base via the rotating shaft, allowing the float 320 to swing around the rotating shaft. The connecting component 310 includes a rotating shaft and a fixed base. The fixed base is installed on the side of the oil cap 2 facing the inside of the oil tank body 1, and it is used to provide mounting support for the rotating shaft. The rotating shaft is arranged horizontally and rotatably connected to the fixed base, forming a fulcrum that can support the float 320. One end of the float 320 is sleeved on the rotating shaft and movably connected to the rotating shaft, allowing the float 320 to swing around the rotating shaft. This allows the float 320 to rotate flexibly under the influence of changes in the oil level inside the oil tank, thereby driving the float ball 330 to follow the oil level movement, ensuring the sensitivity and reliability of the oil level measurement.

[0045] When the float 330 is in the first position, the float rod 320 is in the third position; when the float 330 is in the second position, the float rod 320 is in the fourth position. The angle formed by the float rod 320 in the third and fourth positions is less than or equal to 120 degrees. The float 330 and the float rod 320 are fixedly connected. When the float 330 is in the first position, the float rod 320 is in the third position; when the float 330 is in the second position, the float rod 320 is in the fourth position. The swing angle between the third and fourth positions is less than or equal to 120 degrees. If the swing angle is too large, the float rod 320 will interfere with the internal wall or other components of the oil tank body 1 during movement, affecting the measurement accuracy; if the swing angle is too small, the movement range of the float 330 will be insufficient, and it may not be able to cover the full range of the oil tank from the lowest to the highest liquid level. Therefore, limiting the angle to less than or equal to 120 degrees can balance the movement space, measurement accuracy, and the stability of the mechanical structure.

[0046] The distance between the center of the oil cap 2 and the center of the connecting component 310 is defined as a first length, and the ratio of the length of the float 320 to the first length is less than or equal to 2. To ensure a proper match between the length of the float 320 and the movement path of the float 330, in this embodiment, the distance between the center of the oil cap 2 and the center of the connecting component 310 is defined as the first length. The ratio of the length of the float 320 to the first length is limited to less than or equal to 2. This ratio effectively prevents the float 320 from being too long and causing excessive swaying, avoiding measurement errors or mechanical wear caused by excessive inertial force; it also prevents the float 320 from being too short, ensuring that the float 330 can cover the required measurement range. Through proportional design, the float 320 can maintain a compact structure and sensitive response while meeting the oil level measurement range requirements.

[0047] In practice, the shaft can be made of stainless steel or nickel-plated steel to provide corrosion and wear resistance. The mounting base can be connected to the oil cap 2 by screws, welding, or integral molding, thereby ensuring the overall strength and stability of the connecting component 310. The float 320 is typically made of lightweight, corrosion-resistant metal or high-strength engineering plastic to reduce load and frictional resistance, ensuring smooth oscillation in the oil.

[0048] This embodiment enables the float 320 and float 330 to move stably and smoothly during oil level changes, and ensures that the measurement angle and movement range are within a reasonable range, thereby effectively improving the accuracy and reliability of oil level measurement.

[0049] Furthermore, in this embodiment, the oil cap 2 and the fixing seat are connected by a snap-fit ​​structure. The snap-fit ​​structure consists of a slot on the oil cap 2 and claws on the fixing seat. During installation, the fixing seat is inserted into the slot on the oil cap 2 in a predetermined direction and pressed into place. The claws automatically engage under elastic action, achieving a quick and reliable connection between the fixing seat and the oil cap 2. The snap-fit ​​structure avoids the cumbersome operation of traditional screw connections, significantly improving assembly efficiency. At the same time, this snap-fit ​​structure also facilitates later disassembly and maintenance, making the inspection and cleaning of the float 320 and float ball 330 more convenient.

[0050] The connection between the float 320 and the float ball 330 is a detachable structure. In this embodiment, the detachable structure can be implemented using threaded connections, snap-fit ​​connections, or plug-in connections. With this detachable structure, when the float ball 330 is damaged, aged, or needs to be replaced, it can be easily separated from the float 320 and replaced without disassembling the entire oil level measuring assembly, thereby reducing maintenance costs and improving the maintainability and service life of the equipment.

[0051] The float 320 has a hollow structure, and its interior is filled with a low-density oil-resistant material. The hollow structure, forming a through-cavity, effectively reduces the float 320's weight and shaft load, allowing it to swing sensitively under the buoyancy of the oil and improving the response speed of oil level measurement. Simultaneously, the low-density oil-resistant material filling the float 320, such as foamed polypropylene, polyurethane foam, or closed-cell microspheres, further reduces the overall density of the float 320, increasing its buoyancy in the oil. This allows the float 320 to respond quickly even at low oil levels, and these materials have excellent oil resistance, allowing it to be immersed in oil for extended periods without swelling or degradation.

[0052] The float 320 is equipped with an adjusting counterweight, which can move axially along the float 320. This axial movement changes the center of gravity position of the float 320. By adjusting the position of the counterweight, the balance of the float 320 in the oil can be corrected, thereby fine-tuning the buoyancy response curve of the float 330 to adapt to oils of different viscosities or densities. This not only improves the adaptability of the oil level measurement component but also allows for simple on-site adjustments to optimize measurement accuracy, avoiding measurement errors caused by differences in oil properties.

[0053] The float 330 has an anti-adhesion coating on its surface. This coating can be made of fluorine, silicone, or other low surface energy materials, effectively preventing impurities, colloids, or deposits in the oil from adhering to the surface of the float 330, thus avoiding loss of sensitivity due to surface contamination. This anti-adhesion coating also reduces the frictional resistance between the float 330 and the oil, allowing the float to float more flexibly in the oil and ensuring the stability and long-term reliability of the oil level measurement process.

[0054] This invention significantly expands the oil level measurement range by offsetting the connecting parts of the oil level measuring component from the vertical centerline of the oil cap. This allows the float to cover the lowest to highest point of the oil tank's vertical centerline, solving the problem that traditional oil level gauges often fail to indicate significant residual oil at low levels and have large unrecorded areas at high levels, thus effectively improving the accuracy of oil level indication. The eccentric installation also avoids interference between the float and the inner wall of the oil tank, ensuring smooth float movement, reducing jamming and measurement lag, and improving the reliability and service life of the oil level measuring component. Furthermore, this invention requires no additional complex mechanical structures; improvements are achieved simply by adjusting the installation position, resulting in a simple structure, low manufacturing cost, and convenient installation and maintenance.
