Description

Technical Field

[0001] This utility model relates to the field of monitoring technology for fuel consumption and carbon emissions of construction machinery, specifically to an adaptive caliber-adjustable oil-carbon detector. Background Technology

[0002] Traditional oil pressure gauges suffer from poor adaptability, high cost, and low efficiency due to their fixed-diameter design. Common sizes like Φ50mm and Φ80mm limit their applicability. For example, a construction site needs to deploy both Φ40mm forklifts and Φ150mm dump trucks. To meet measurement requirements, two types of dedicated oil pressure gauges must be purchased, costing a hefty 12,000 yuan. More importantly, after the equipment is replaced, over 60% of these dedicated oil pressure gauges remain idle, resulting in significant resource waste.

[0003] On the other hand, traditional solutions attempt to achieve compatibility with the fuel gauge by modifying the fuel tank interface. However, this approach has significant drawbacks. A single modification costs approximately 800 yuan and takes more than 30 minutes, making it extremely inefficient. This not only increases operating costs but also prolongs equipment downtime, negatively impacting the normal progress of construction site operations. Utility Model Content

[0004] In view of this, the present invention provides an adaptive caliber adjustable oil carbon detector, which can adjust the caliber and solve the problems of poor adaptability and high procurement cost of existing fixed caliber oil carbon meters.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An adaptive caliber-adjustable oil carbon detector includes an oil tank interface base, a sliding arc plate sleeve, a movable arc plate, a positioning component, a sensor, and an electronic information transmission module;

[0007] Three or more sets of sliding arc plate sleeves are evenly distributed around the circumference of the oil tank interface base and slide radially along the oil tank interface base; the movable arc plate is inserted into the gap between adjacent sliding arc plate sleeves and can slide along the gap between the sliding arc plate sleeves to cooperate with the sliding arc plate sleeves to achieve diameter adjustment, and is locked and positioned by the positioning member located inside the sliding arc plate sleeve;

[0008] The sensor is located inside the fuel tank and is electrically connected to the electronic information transmission module outside the fuel tank interface base via a wire.

[0009] Furthermore, the aperture adjustment is an adjustment of several fixed apertures.

[0010] Furthermore, the inner bottom surface of the oil tank interface base is provided with a T-shaped groove extending radially, and the number of T-shaped grooves is consistent with the number of sliding arc plate sleeves.

[0011] Furthermore, the sliding arc plate assembly includes two arc-shaped metal plates, which are spaced a certain distance apart and are used to fit into the movable arc plate; the upper ends of the two arc-shaped metal plates are provided with T-shaped sliders that slide in conjunction with the T-shaped grooves.

[0012] Furthermore, the outer wall surface of the movable arc plate is provided with scale grooves corresponding to several fixed diameters.

[0013] Furthermore, the movable arc plate is made of spring steel and has a galvanized surface for rust prevention.

[0014] Furthermore, the positioning components are locking bolts and nuts, and each T-shaped groove is provided with several bolt positioning holes that penetrate the bottom surface of the oil tank interface base. The number of bolt positioning holes is consistent with the number of fixing holes and their positions correspond.

[0015] Furthermore, the fuel tank interface base and the fuel tank opening are sealed by a sealing element.

[0016] Furthermore, the sealing element is a heat shrink tubing or a sealing ring.

[0017] Furthermore, the movable arc plate is provided with dovetail grooves on both sides, and the inner wall of the two arc-shaped metal plates is provided with dovetail sliders that slide in cooperation with the dovetail grooves.

[0018] Beneficial effects:

[0019] 1. This utility model achieves diameter adjustment through the sliding fit between the movable arc plate and the sliding arc plate sleeve, which can be adapted to more than 95% of construction machinery. It has good adaptability and low cost. Compared with purchasing multiple fixed diameter oil and carbon meters, the purchase cost of a single device is reduced by 70%. Moreover, the adjustment can be achieved by pushing and pulling the sliding arc plate sleeve, and the adjustment time is ≤3 minutes, which improves efficiency by 80% compared with traditional modification schemes.

[0020] 2. The outer wall of the movable arc plate of this utility model is provided with scale grooves corresponding to several fixed diameters, which can achieve quick positioning during adjustment and find the fixed diameter that needs to be adjusted.

[0021] 3. The movable arc plate of this utility model is made of spring steel. The high elastic modulus and elastic limit of spring steel enable it to store a large amount of elastic potential energy when under compression or tension, and can quickly return to its original shape after the load is removed. Moreover, it is not prone to plastic deformation or fracture during repeated deformation, and its fatigue life is stable. Secondly, the surface of the movable arc plate is treated with galvanized anti-rust coating. The galvanized layer forms a dense protective film of zinc oxide or basic zinc carbonate on the surface, which effectively isolates the direct contact of corrosive media such as oxygen, moisture and salt spray, thereby significantly reducing the oxidation rate of the base metal and significantly improving the overall performance and service life of the movable arc plate.

[0022] 4. This utility model achieves locking and positioning of the movable arc plate and the sliding arc plate sleeve by means of locking bolts, which is simple in structure and convenient in operation.

[0023] 5. This utility model uses heat shrink tubing or sealing rings as sealing elements, which can effectively prevent liquid, gas or dust from seeping in and ensure reliable sealing; it can also be matched with surfaces of different shapes (such as circular and irregular structures) to provide a uniform sealing effect and has strong adaptability; it also has a certain degree of temperature resistance and chemical corrosion resistance, adapts to various working conditions, does not require complicated tools or long-term curing, and can quickly complete the sealing operation, improving efficiency.

[0024] 6. The movable arc plate and the arc-shaped metal plate of this utility model are slidably connected through a dovetail groove and a dovetail slider, which has high rigidity and high precision. Its trapezoidal cross-section design can effectively resist lateral forces and overturning moments. The fit clearance can be finely adjusted by the wedge to ensure high long-term motion accuracy and reliability. This connection method is simple to process and easy to maintain, does not rely on rolling elements, and has low cost. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] This invention provides an adaptive caliber-adjustable oil carbon detector, such as... Figure 1 , Figure 2 , Figure 3 As shown, the adaptive caliber adjustment oil carbon detector includes an oil tank interface base 1, a sliding arc plate sleeve 2, a movable arc plate 3, a positioning component, a sensor 9, and an electronic information transmission module 11.

[0032] Three or more sets of sliding arc plate sleeves 2 are evenly distributed around the fuel tank interface base 1, and the sliding arc plate sleeves 2 slide radially along the fuel tank interface base 1; the movable arc plate 3 is inserted into the gap between adjacent sliding arc plate sleeves 2, and the movable arc plate 3 can slide along the gap between the sliding arc plate sleeves 2, cooperate with the sliding arc plate sleeves 2 to realize the diameter adjustment, and achieve locking and positioning through the positioning part located inside the sliding arc plate sleeves 2; the sensor 9 is located inside the fuel tank and is electrically connected to the electronic information transmission module 11 outside the fuel tank interface base 1 through the wire 10, and is used to monitor the fuel level change in real time and calculate carbon emissions.

[0033] Specifically, sensor 9 and electronic information transmission module 11 integrate a high-precision liquid level sensor (error ±1%), an STM32 data processing chip, and a 4G wireless transmission unit, supporting real-time carbon data upload to the cloud platform.

[0034] The fuel tank interface base 1 is a cylindrical shell structure, open at one end and with a through hole at the other end. The diameter of the through hole is smaller than the diameter of the cylindrical shell. The open end faces upward, and the end face where the through hole is located is the bottom surface. The fuel tank interface base 1 is made of aluminum alloy. In this embodiment, the bottom surface of the fuel tank interface base 1 is uniformly provided with three radially extending T-shaped grooves 4. The number of T-shaped grooves 4 is the same as the number of sliding arc plate sleeves 2. The cross-sectional dimensions of the T-shaped grooves 4 are 10mm × 6mm. It should be noted that the length of the T-shaped grooves 4 covers the upper and lower limits of the required fixed diameter, and there is no problem of the sliding arc plate sleeve 2 detaching from the movable arc plate 3.

[0035] In one embodiment, a bolt positioning hole 7 is provided above the T-shaped groove 4, such as... Figure 2 As shown, the bolt positioning hole 7 is an elongated fixing hole extending radially. The positioning components are a locking bolt 6 and a nut. The locking bolt 6 passes through the bolt positioning hole 7 from the inside of the oil tank interface base 1 and extends out of the T-shaped slide groove 4, where it is threadedly connected to the nut to achieve locking, thereby positioning the sliding arc sleeve 2. This allows for adjustment of any diameter.

[0036] In this embodiment, the diameter adjustment involves adjusting several fixed diameters. The bolt positioning holes 7 correspond to several fixed diameters, and the number of fixed diameters to be adjusted is the same as the number of fixed holes, with each fixed diameter corresponding to one fixed hole. Each T-shaped groove 4 has a bolt positioning hole 7 that penetrates the bottom surface of the oil tank interface base 1. The positioning components are locking bolts 6 and nuts.

[0037] The sliding arc plate assembly 2 includes two arc-shaped metal plates spaced a certain distance apart for interlocking with the movable arc plate 3; the upper ends of the two arc-shaped metal plates are provided with T-shaped sliders that slide in conjunction with the T-shaped grooves 4. The arc-shaped metal plates are made of 304 stainless steel with a thickness of 2mm, and the radius of curvature of the arc can cover a range of Φ30-200mm.

[0038] The movable arc plate 3 is made of spring steel with a galvanized surface for rust prevention. It is 0.5mm thick and has a maximum expansion and contraction deformation of 15mm.

[0039] The outer wall of the movable arc plate 3 is provided with scale grooves 8 corresponding to several fixed diameters, which facilitates observation and quick positioning.

[0040] The movable arc plate 3 has dovetail grooves 5 on both sides, and the inner walls of the two arc-shaped metal plates have dovetail sliders that slide in conjunction with the dovetail grooves 5. Alternatively, dovetail sliders can be provided on both sides of the movable arc plate 3, and dovetail grooves 5 can be provided on the inner walls of the two arc-shaped metal plates. The depth of the dovetail grooves 5 is 2mm, and the maximum width is 5mm, ensuring a balance between sliding freedom and friction.

[0041] In this embodiment, the sliding engagement of the movable arc plate 3 with the two arc-shaped metal plates can cover a diameter of Φ30-200mm, adapting to over 95% of construction machinery. Based on commonly used oil tank diameters (Φ25mm, Φ40mm, Φ50mm, Φ75mm, Φ150mm), five bolt positioning holes 7 can be correspondingly set on the oil tank interface base 1, each corresponding to one of these five diameters. Simultaneously, five scale grooves 8 are set on the outer wall of the movable arc plate 3, also corresponding to one of these four diameters. By pushing and pulling the sliding arc plate sleeve 2, the diameter of the oil carbon detector can be quickly adjusted to the required value, such as Φ25mm. Of course, more bolt positioning holes 7 and scale grooves 8 can be set according to the usage requirements of the oil tank diameter.

[0042] The fuel tank interface base 1 is sealed to the fuel tank opening via a seal. The seal is either heat shrink tubing or a sealing ring. The heat shrink tubing is made of oil-resistant rubber and has a temperature tolerance range of -40℃ to 120℃.

[0043] The following explanation uses a Φ40mm diesel forklift and a Φ150mm dump truck as examples:

[0044] like Figure 4As shown, when adjusting the Φ40mm diameter, loosen the locking bolts 6 and nuts of the three sets of sliding arc plate sleeves 2, push the arc-shaped metal plate to the "Φ40" position of the scale groove 8, and then tighten it again with the locking bolts 6 and nuts; push and pull the movable arc plate 3 to make it fit tightly against the inner edge of the forklift fuel tank opening, forming a complete sealing ring; install heat shrink tubing (sealing strip) at the contact point of the forklift fuel tank opening and fix it with heat. Alternatively, a sealing ring can be used for sealing; select the appropriate sealing component according to the on-site construction.

[0045] When adjusting the Φ150mm diameter, loosen the locking bolts 6 and nuts of the three sets of sliding arc plate sleeves 2. The sliding arc-shaped metal piece moves to the "Φ150" position of the scale groove 8 and is then locked again by the locking bolts 6 and nuts. At this time, the movable arc plate 3 extends to its maximum deformation and fits the inner edge of the truck fuel tank opening. A sealing ring can be used instead of heat shrink tubing to enhance pressure resistance (≥0.5MPa). Before assembling with the truck fuel tank opening, a sealing ring is fitted onto the outside of the locked sliding arc plate sleeve 2.

[0046] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
