Description

Technical Field

[0001] This invention relates to the field of oil tanker refueling technology, and particularly to an oil tanker refueling system and method based on modular integration. Background Technology

[0002] According to statistics from the Ministry of Industry and Information Technology, there are currently about 60 domestic manufacturers of oil tanker trucks, producing 440 different models, with a total fleet of over 200,000 units. These trucks can transport gasoline, diesel, jet fuel, and other fuels, with a capacity of 3 cubic meters per second. 3 -60m 3 The problem persists across cities, towns, and highway networks nationwide. Many civilian oil tankers only transport fuel, not refuel, and lack their own refueling capabilities. They rely on gas stations for fuel supply, hindering their ability to operate independently. Therefore, there is an urgent need to develop a refueling device that integrates fuel transport, purification, metering, and refueling functions. This device can be easily installed on oil tankers, expanding their functionality and improving their efficiency to meet the fuel supply needs of wartime or national emergency relief efforts.

[0003] Therefore, it is urgent to design a refueling system for oil tankers that has pumping, filling and information collection functions. Summary of the Invention

The oil delivery control unit supports simultaneous dual-nozzle dispensing, with a single-nozzle flow rate range of 50-120 L / min and a pressure adjustment range of 0.2-0.3 MPa. The oil delivery control unit adopts an integrated design. The pump inlet of the oil delivery control unit is connected to the oil tank suction pipe via a self-sealing connector (DN25), and the outlet of the oil delivery control unit is connected to a filter separator via a flange interface. The oil delivery control unit has a built-in overload protection module that automatically cuts off the power supply when the current is abnormal (≥120% of the rated value).

[0011] A modularly integrated method for refueling oil tankers, comprising the following steps: S1, Module Pre-installation: The power supply unit, oil delivery control unit, purification metering unit, and data management unit are assembled into the modular enclosure through standardized electrical and mechanical interfaces.

[0012] S2, Vehicle-mounted installation: Small oil tanker (capacity ≤15m³) 3 ): The modular box is divided into an oil conveying and purification unit and a metering and filling unit, which are fixed to the top platform of the oil tank and the original vehicle toolbox, respectively. The oil tank suction pipe (DN25 hose) and the oil pump inlet are connected by a flange interface. Large oil tanker (capacity > 30m) 3 The original vehicle toolbox is replaced with an integrated modular box, which is fixed to the side of the vehicle frame with quick-release bolts. The suction pipe is quickly connected between the box and the oil tank through a self-sealing connector, and the power line is connected to the chassis 24V DC system. S3, System Self-Check: After starting the power supply unit, the system performs the following self-check procedure: oil pump no-load pressure test (target pressure 0.25MPa, deviation ≤5%). Zero-point calibration and range verification of digital flow meters (error ≤ ±1%). Filter separator sealing test (no leakage); Wireless communication module connectivity test (4G / 5G signal strength ≥-90dBm); S4, Fuel Refueling Operation: Select the fuel type (including but not limited to gasoline and diesel), set the single refueling volume (range 50-2000L) and flow mode (including but not limited to single nozzle and dual nozzle) via the touch screen.

[0015] Figure 1 This is a schematic diagram of the process of the present invention; Figure 2 This is a schematic diagram of the modified layout of the present invention; Figure 3This is a schematic diagram showing a modified arrangement for another embodiment of the present invention.

[0016] In the diagram, 1 is the oil conveying and purification unit; 2 is the metering and filling unit; and 3 is the suction pipe. Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] Example 1 addresses the issue of civilian oil tanker trucks lacking purification and metering refueling functions. It provides two modularly integrated oil tanker truck refueling modification methods, depending on the vehicle model and the size of the supporting equipment: First, there are oil tankers with smaller capacity and smaller toolboxes. For example, oil tankers with a capacity of 10m³... 3 The following oil tankers typically have toolboxes smaller than 1000mm × 600mm × 800mm, making it difficult to install all the modified equipment inside. The platform on top of the oil tank also has a large area. For these vehicles, the modified equipment is assembled according to its function and structural characteristics, and then installed separately in the platform and toolbox. Specifically, the oil delivery and control unit and the oil purification unit are installed on a fixed platform to form the oil delivery and purification unit, which is then installed on the oil tank platform. The metering and filling unit is installed in the original vehicle toolbox. The modification layout is shown in the diagram below. Figure 2 As shown.

[0019] Secondly, there are larger capacity oil tankers. Due to their larger size, these vehicles have larger toolboxes on both sides. The modification method for this type of vehicle involves fixing the oil delivery and control unit, oil purification unit, and metering and dispensing unit into a rectangular box to form an oil dispensing unit. This is accomplished by interchangeable toolboxes and the oil dispensing unit. A modification layout diagram is shown below. Figure 3 As shown.

[0020] The two schemes were compared in terms of modification methods, power selection, installation and protection of modification equipment, filtration, metering and filling, refueling data processing, safety, vehicle passability, vehicle stability, and ergonomics. The comparison results are shown in the table below:

[0021] Based on the comparison of the above aspects, Scheme 1 is superior to Scheme 2 in terms of overall concept, system configuration, and key technology handling. Furthermore, Scheme 1 adds an oil return function compared to Scheme 2, making it easier to remove residual oil from the pipeline after it is returned to the oil tank, while the increased economic cost and modification difficulty are not significant. Therefore, considering all factors, Scheme 1 will be adopted for the development work.

[0022] Therefore, this embodiment combines Scheme 1 to design a modularly integrated refueling system for oil tankers, including: Power supply unit: Provides dual-mode power support; Oil delivery control unit: used to drive the pump and regulate the flow rate; Purification and metering unit: used for oil filtration and precise metering; Data Management Unit: Encrypts, stores, and transmits injection data; Modular enclosure: adaptable for quick vehicle installation; The power supply unit is integrated into the cabinet through a standardized interface. The power supply unit supports dual-mode input of 24V DC power and 220V AC power, and has a built-in intelligent charging and discharging management module to realize real-time monitoring and automatic switching of power status. The power supply unit is equipped with a maintenance-free lead-acid battery pack with a capacity of ≥165AH, which supports offline driving range of ≥5 hours and can be charged through the chassis engine's built-in generator or mains power. It is equipped with an explosion-proof rating of ExdⅡBT4 and a protection rating of IP56, which meets the safety requirements of oilfield operation environments.

[0023] The oil delivery control unit is integrated into the housing through a standardized interface. The oil delivery control unit integrates a DC brushless motor, a self-priming pump and a control device into a single structure, realizing the functions of oil pumping, pipeline evacuation and flow regulation. The oil delivery control unit supports simultaneous dual-gun filling, with a single-gun flow rate range of 50-120L / min and a pressure adjustment range of 0.2-0.3MPa. It also features automatic shutdown protection for pressure over-limit (>0.3MPa). The control device achieves dynamic flow balance, ensuring that pressure fluctuation is ≤5% during dual-gun filling. It is equipped with a self-priming function with a self-priming time of ≤60s to meet the low-level oil suction requirements of the oil tank. The oil delivery control unit adopts an integrated design, reducing its volume to ≤0.1m. 2 The total weight is ≤15kg. It is compatible with modular box installation. The oil conveying control unit's suction pump inlet is connected to the oil tank suction pipe through a self-sealing connector (DN25). The oil conveying control unit's outlet is connected to the filter separator through a flange interface. The oil conveying control unit has a built-in overload protection module that automatically cuts off the power supply when the current is abnormal (≥120% of the rated value).

[0024] The purification metering unit is integrated into the box through a standardized interface. The purification metering unit adopts a multi-stage filter separator with an integrated structure of coalescing filter and separation filter. The filtration accuracy is ≤10um, which is suitable for the purification of gasoline and diesel oil. The purification metering unit is equipped with an integrated digital flow meter and an encrypted storage module to record data such as single filling volume, cumulative filling volume, oil type and time in real time. The purification metering unit supports simultaneous dual-nozzle injection, with a single-nozzle flow rate range of 50-120L / min and a pressure adjustment range of 0.2-0.3MPa. It is also equipped with an emergency pipeline evacuation function.

[0025] The data management unit is integrated into the enclosure through a standardized interface. The data management unit encrypts and uploads the filling data to the cloud platform through a wireless communication module (4G / 5G), supporting remote monitoring and report generation. The data management unit has a built-in handheld data acquisition device that can read data stored by the digital flow meter offline and generate Excel-format statistical reports through decryption software; The data management unit is equipped with a data storage module, which uses the AES-256 encryption algorithm to meet military-grade information security standards.

[0026] The modular enclosure is compatible with oil tanker toolboxes or overhead walkways and is secured with quick-release devices. Featuring anti-slip brackets and a waterproof cover, the enclosure boasts an IP54 protection rating, making it suitable for complex outdoor environments. Built-in quick-release interfaces and flange connectors allow for rapid deployment and retraction of tank suction pipes, power lines, and communication lines.

[0027] This embodiment also provides a modularly integrated method for refueling oil tankers, such as... Figure 1 As shown, it includes the following steps: S1, Module Pre-installation: The power supply unit, oil delivery control unit, purification metering unit and data management unit are assembled into the modular enclosure through standardized electrical and mechanical interfaces to ensure the integrity of the functional links of each unit. Before the enclosure is sealed, the unit is powered on to verify the oil pump start-up and shutdown, flow regulation, filtration and separation effect and data acquisition function to ensure that there are no compatibility conflicts in the modular integration.

[0028] S2, Vehicle-mounted installation: Small oil tanker (capacity ≤15m³) 3 ): The modular box is divided into an oil conveying and purification unit and a metering and filling unit, which are fixed to the top platform of the oil tank and the original vehicle toolbox, respectively. The oil tank suction pipe (DN25 hose) and the oil pump inlet are connected by a flange interface. Large oil tanker (capacity > 30m) 3 The original vehicle toolbox is replaced with an integrated modular box. It is fixed to the side of the vehicle beam with quick-release bolts. The suction pipe is quickly connected between the box and the oil tank through a self-sealing connector. The power line is connected to the chassis 24V DC system. After installation, check the gap between the box and the vehicle structure to ensure that there is no interference. A waterproof cover and anti-slip bracket are added. The protection level is not lower than IP54. S3, System Self-Check: After starting the power supply unit, the system performs the following self-check procedure: oil pump no-load pressure test (target pressure 0.25MPa, deviation ≤5%). Zero-point calibration and range verification of digital flow meters (error ≤ ±1%). Filter separator sealing test (no leakage); Wireless communication module connectivity test (4G / 5G signal strength ≥-90dBm); If the self-test fails, the system will display a fault code (such as "E01: Oil pump pressure abnormal") on the control panel and lock the filling function until the fault is resolved. S4, Fuel Refueling Operation: Select the fuel type (including but not limited to gasoline and diesel), set the single refueling volume (range 50-2000L) and flow mode (including but not limited to single nozzle and dual nozzle) via the touch screen. Start the oil delivery control unit; the self-priming pump will pump the oil from the oil tank through the suction pipe to the purification and metering unit, with a filtration accuracy of ≤10µm. The digital flow meter monitors flow rate in real time (accuracy ±0.5%), and the data is encrypted, stored, and synchronously uploaded to the cloud platform. The operator uses a digital refueling nozzle (explosion-proof rating ExibIIAT3) to perform refueling. In dual-nozzle mode, the flow rate of a single nozzle is ≥60L / min, and the system automatically balances the pressure of the two nozzles. If a pipe blockage or pressure exceeding the limit (>0.3MPa) is detected, the system will trigger an emergency shutdown, initiate a pipe purging procedure, and provide an audible and visual alarm. The encrypted data storage has a local caching mechanism, and when the network is offline, the data is temporarily stored in the encrypted storage. S5, Retraction and Maintenance: After the operation is completed, start the "drain mode" and the oil pump will run in reverse to pump the residual oil in the pipeline back to the oil tank to avoid oil residue contamination. Disconnect the quick-release interface from the flange, remove the modular housing, clean the external oil stains, and store it in a dry environment. The system automatically generates maintenance logs, recording the duration of the operation, the total amount of fuel added, the equipment status, and the history of faults. It also exports encrypted reports (Excel format) through the data management unit for subsequent maintenance analysis.

[0029] In terms of installation, this embodiment allows for flexible selection of methods based on vehicle model without affecting vehicle performance; it has a complete self-inspection process to ensure normal equipment operation; at the same time, data processing is efficient and secure, supporting encrypted storage and uploading; it also has an emptying mode to avoid oil residue contamination and facilitates maintenance.
