Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and more specifically, relates to an oil testing device for multi-fuel engine models. Background Technology

[0002] Engine oil, also known as motor oil, has a density of approximately 0.91 × 10³ kg / m³. It plays a vital role in engine lubrication, friction reduction, cooling, leak prevention, rust and corrosion prevention, and shock absorption. It is often referred to as the "blood" of a car. Engine oil consists of two main components: base oil and additives. Base oil is the primary component, determining the oil's basic properties, while additives compensate for and improve upon the base oil's shortcomings, imparting new properties and forming an important part of the engine oil composition.

[0003] In the operation and maintenance management of large-scale multi-fuel power equipment, oil condition monitoring is a core component to ensure reliable engine operation. Traditional monitoring methods typically rely on visual observation of the oil level in the reservoir. The inventors believe this method suffers from significant technical bottlenecks: insufficient reading accuracy; significant differences in oil viscosity and transparency due to different fuel types (such as diesel / biofuel / synthetic fuel), leading to unstable reflective properties of the oil surface; and substantial visual errors caused by operators looking upwards or downwards, severely impacting the accuracy of oil consumption rate calculations. Utility Model Content

[0004] One objective of this invention is to improve the accuracy of oil consumption rate observation.

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an oil testing device for multi-fuel engine models.

[0006] To achieve the aforementioned objectives, the present invention employs a technical solution comprising a storage box and a test tube. The storage box is hollow, with an injection port at one end, located on the lower side of one side of the storage box and horizontally oriented along its axis. The test tube is positioned above the storage box and vertically oriented along its axis. A cover plate is slidably connected inside the test tube, and the outer circumferential surface of the cover plate abuts against the inner wall of the test tube. Limiting blocks are symmetrically arranged on both sides of the cover plate, and limiting grooves are formed inside the test tube at positions corresponding to the limiting blocks. The opening direction of the limiting grooves is the same as the length direction of the test tube, and the limiting blocks can slide within the limiting grooves along the opening direction of the limiting grooves.

[0007] Optionally, the lower end of the outer circumference of the test tube is provided with an external thread, and the storage box is provided with a fixing ring corresponding to the test tube. The fixing ring is coaxial with the test tube, and the inner wall of the fixing ring is provided with an internal thread corresponding to the external thread position of the test tube. The internal thread of the fixing ring and the external thread of the test tube can be matched and tightened together.

[0008] Optionally, a through hole is provided in the middle of the cover plate, the axis of the through hole is collinear with the axis of the cover plate, the width of the limiting block of the cover plate is smaller than the width of the limiting groove, the limiting block of the cover plate can slide in the limiting groove, and the ends of the two limiting blocks that are far apart from each other can abut against the groove of the limiting groove.

[0009] Optionally, the density of the cover plate is lower than that of the engine oil, allowing the cover plate to float above the engine oil. The position of the cover plate is used to read the scale groove, thus achieving accurate measurement of the amount of engine oil in the test tube. The limiting block cooperates with the limiting groove to restrict the cover plate to slide only in the vertical direction.

[0010] Optionally, an abutment ring is provided at the position corresponding to the internal thread inside the fixing ring. The abutment ring is located on the side of the internal thread close to the storage box, and one end of the test tube can abut against the abutment ring.

[0011] Optionally, fluorescent blocks are embedded in the edge of the cover plate, and the cover plate has a certain thickness so that the error caused by looking up and down when reading is smaller than the error caused by only observing the page.

[0012] Optionally, the cover plate is provided with an inclined slope, with the edge of the cover plate being the end of the inclined slope that is higher and the through hole of the cover plate being the end of the inclined slope that is lower.

[0013] Compared with the prior art, the advantages of this utility model include: (1) This utility model provides an oil testing device for multi-fuel engines, which improves installation convenience and sealing performance: the device can be quickly installed and disassembled by tightening the external thread of the test tube and the internal thread of the fixing ring, and no complicated tools are required during operation. The design of the abutment ring effectively limits the screwing depth of the test tube, ensuring the connection is stable and avoiding structural damage or sealing failure due to excessive tightening; the tight fit between the storage box and the test tube interface can prevent oil leakage and adapt to the testing needs of multi-fuel engines under complex operating conditions; (2) This utility model provides an oil testing device for multi-fuel engines, which accurately reads the oil level and controls errors: the cover plate automatically floats on the liquid surface because its density is lower than that of the oil. The cooperation between the limiting blocks on both sides of the cover plate and the limiting groove inside the test tube forces the cover plate to move only in the vertical direction, completely eliminating the influence of horizontal shaking on the reading. The scale grooves are arrayed along the axial direction of the test tube. Combined with the thickness design of the cover plate edge, the visual error when reading from above or below is reduced compared with the traditional liquid surface observation method, and the detection accuracy is significantly improved. (3) The present invention provides an oil testing device for multi-fuel engines, which optimizes residual oil and enhances reading efficiency: the inclined slope structure on the cover plate guides the residual oil on the liquid surface to the central through hole. Actual tests show that the amount of oil remaining on the cover plate surface after a single test is reduced to less than 0.5 mL, avoiding volume calculation deviation caused by residual oil adhesion; the fluorescent block embedded on the edge of the cover plate can clearly mark the liquid surface position in a low light environment, and the operator can complete the reading without additional lighting, thus improving the detection efficiency.

[0023] This utility model embodiment is intended to introduce and explain the structural composition of an oil testing device for multi-fuel engines and the cooperation relationship between the various components. Unless otherwise specified, the dimensions, materials, and manufacturing processes of the various components suitable for an oil testing device for multi-fuel engines in this utility model embodiment can be selected according to specific circumstances, and no special limitations or explanations are made here.

[0024] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0025] Example 1 Please see Figure 1-4 As shown, an oil testing device for multi-fuel engines includes a storage tank 1, which is a cavity. One end of the storage tank 1 has an injection port 11 located on the lower side of one side, with its axis horizontal. A test tube 2 is positioned above the storage tank 1, with its axis vertical. The lower end of the outer circumference of the test tube 2 has an external thread. A fixing ring 12 is provided in the storage tank 1 corresponding to the test tube 2, and the fixing ring 12 is coaxial with the test tube 2. An internal thread is provided on the inner wall of the fixing ring 12 corresponding to the external thread of the test tube 2, allowing the internal thread of the fixing ring 12 to be tightened into the external thread of the test tube 2. An abutment ring 13 is provided inside the fixing ring 12 corresponding to the internal thread, located on the side of the internal thread close to the storage tank 1, allowing one end of the test tube 2 to abut against the abutment ring 13.

[0026] In use, the test tube 2 is aligned with the abutment ring 13 of the storage box 1. The internal thread of the abutment ring 13 and the external thread of the test tube 2 cooperate with each other to fix the relative position of the test tube 2 and the storage box 1. The abutment ring 13 set inside the fixing ring 12 limits the screwing distance of the test tube 2 after the test tube 2 is rotated into the fixing ring 12.

[0027] Please see Figure 1-4 As shown, a scale groove 21 is provided inside and outside the test tube 2. The scale groove 21 is arrayed along the length direction of the test tube 2. A cover plate 22 is slidably connected inside the test tube 2. The outer peripheral surface of the cover plate 22 can abut against the inner wall of the test tube 2. Limiting blocks 23 are symmetrically arranged on both sides of the cover plate 22. A limiting groove 24 is provided inside the test tube 2 at the position corresponding to the limiting block 23. The opening direction of the limiting groove 24 is the same as the length direction of the test tube 2. The limiting block 23 can slide within the limiting groove 24 along the opening direction of the limiting groove 24.

[0028] During use, engine oil is poured into storage tank 1 through test tube 2. After storage tank 1 is full, engine oil is stored in test tube 2. The density of cover plate 22 is lower than that of engine oil, allowing cover plate 22 to float above the engine oil. The scale groove 21 is read by the position of cover plate 22 to accurately measure the amount of engine oil in test tube 2. Due to the function of limiting grooves 24 on both sides of cover plate 22, the limiting block 23 of cover plate 22 is slidably connected to the limiting groove 24. When engine oil is added or reduced, the limiting groove 24 limits the relative sliding direction of the limiting block 23, restricting the sliding direction of cover plate 22 to only the vertical direction, so that cover plate 22 moves with the amount of engine oil. Cover plate 22 has a certain thickness, so that the error value caused by looking up and down when reading is smaller than the error caused by only observing the page.

[0029] Please see Figure 1-4 As shown, a through hole 25 is provided in the middle of the cover plate 22, and the axis of the through hole 25 is collinear with the axis of the cover plate 22. A fluorescent block 26 is embedded in the edge of the cover plate 22. The width of the limiting block 23 of the cover plate 22 is smaller than the groove width of the limiting groove 24. The limiting block 23 of the cover plate 22 can slide in the limiting groove 24. The ends of the two limiting blocks 23 that are far apart from each other can abut against the groove of the limiting groove 24. An inclined slope 27 is provided on the cover plate 22. The edge of the cover plate 22 is the higher end of the inclined slope 27, and the through hole 25 of the cover plate 22 is the lower end of the inclined slope 27.

[0030] During use, after the engine oil is injected, the engine oil is connected through the through hole 25 on the cover plate 22. The cover plate 22 is provided with an inclined slope 27, which tilts the engine oil into the through hole 25, reducing the amount of engine oil remaining on the cover plate 22 and reducing the generation of error values. The fluorescent block 26 provided on the cover plate 22 can quickly locate the position of the cover plate 22 during operation and take a reading. Because the width of the limiting block 23 is smaller than the width of the limiting groove 24, the limiting block 23 and the cover plate 22 can swing in the limiting groove 24. Since the end of the limiting block 23 abuts against the inner wall of the limiting groove 24, the cover plate 22 can only be placed through the end of the test tube 2.

[0031] The effect of this utility model is: 1. Improved ease of installation and sealing: The device can be quickly installed and disassembled by tightening the external thread of the test tube 2 with the internal thread of the retaining ring 12, without the need for complicated tools. The design of the abutment ring 13 effectively limits the screwing depth of the test tube 2, ensuring a stable connection and preventing structural damage or seal failure due to over-tightening; the tight fit between the storage box 1 and the interface of the test tube 2 prevents oil leakage, adapting to the testing needs of multi-fuel engine models under complex operating conditions.

[0032] 2. Accurate Oil Level Reading and Error Control: Because the cover plate 22 has a lower density than the oil, it automatically floats on the surface. The cooperation between the limiting blocks 23 on both sides and the limiting grooves 24 inside the test tube 2 forces the cover plate 22 to move only vertically, completely eliminating the influence of horizontal shaking on the reading. The scale grooves 21 are arrayed along the axial direction of the test tube 2. Combined with the edge thickness design of the cover plate 22, the visual error when reading from above or below is reduced compared to the traditional liquid surface observation method, significantly improving detection accuracy.

[0033] 3. Optimization of residual oil and enhanced reading efficiency: The inclined slope 27 structure on the surface of the cover plate 22 guides the residual oil on the liquid surface to the central through hole 25. Actual tests show that the amount of oil remaining on the surface of the cover plate 22 after a single test is reduced to less than 0.5mL, avoiding volume calculation deviation caused by residual oil adhesion; the fluorescent block 26 embedded on the edge of the cover plate 22 can clearly mark the liquid surface position in low light environment, and the operator can complete the reading without additional lighting, thus improving the detection efficiency.

[0034] 4. Multi-scenario adaptability and maintenance convenience: The equipment structure adopts a modular design, and the test tube 2 and storage box 1 can be separated for cleaning to avoid cross-contamination of different fuel oils; the cover plate 22 with through hole 25 is designed to allow the oil to flow freely, and no manual intervention is required to balance the liquid level during the testing process.

[0035] It should be understood that the above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. It should not be considered that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
