Description

Technical Field

[0001] The utility model belongs to the technical field of ship auxiliary equipment, and in particular relates to an auxiliary fuel filling system for a tugboat. Background Art

[0002] In the daily operations of ships and tugboats, fueling is an essential and critical step in maintaining normal navigation. However, this process presents a number of safety hazards, particularly those related to static electricity accumulation and inadequate fueling monitoring. When fuel is transferred through pipes, valves, and other equipment, significant amounts of static electricity are generated due to friction between oil molecules and interaction between the oil and the pipes, valves, and vessel walls. Due to the poor electrical conductivity of oil, this static electricity tends to accumulate rapidly. When the voltage rises to a certain level, it can trigger static discharge, potentially causing fuel fires and posing a serious threat to the safety of the vessel and personnel.

[0003] Especially when fuel is refueled through non-metallic pipes, the accumulation of static electricity voltage is more significant due to the insulating properties of non-metallic materials, increasing the risk of fire and explosion. Furthermore, controlling the refueling speed is crucial. The faster the refueling speed, the more intense the friction between the oil and components such as pipes and valves, generating more static electricity, further exacerbating safety hazards. Existing refueling systems often focus only on the total amount of fuel refueled, while neglecting real-time monitoring of key parameters such as fuel flow rate during the refueling process. This lack of monitoring makes it difficult for operators to promptly detect and address anomalies during the refueling process, increasing the potential for safety accidents. Summary of the Invention

[0004] The purpose of this utility model is to provide a tugboat auxiliary fuel filling system to solve the problems existing in the prior art.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A tugboat auxiliary fuel filling system includes a fuel filling application integrated machine and several data collection boxes. The data collection boxes are installed at the fuel tank of the fuel filling application integrated machine through guide rails. Each data collection box is provided with an air switch, a terminal block, a transformer, a router, a first data collector and a second data collector. The first end of the air switch is connected to an external power supply, and the second end of the air switch is connected to the input end of the transformer through the terminal block. The router, the first data collector and the second data collector are all connected to the output end of the transformer. The first end of the first data collector is connected to a fuel filling flow meter through the terminal block, and the fuel filling flow meter is installed at the fuel filler of the fuel filling application integrated machine. The first end of the second data collector is connected to a liquid level sensor through the terminal block, and the liquid level sensor is installed in the fuel tank of the fuel filling application integrated machine. The second end of the first data collector and the second end of the second data collector are both connected to the console of the fuel filling application integrated machine through the router.

[0007] A further improvement of the technical solution is that it also includes an alarm, which is connected to the console of the fuel filling application integrated machine.

[0008] Further improvements to the technical solution include a video monitoring control switch and at least one camera, each of which is connected to the console of the fuel filling application all-in-one machine through the video monitoring control switch to obtain the crew's work status and determine whether the crew is smoking based on human body detection.

[0009] A further improvement of the technical solution is that the control console of the fuel filling application machine includes a central processing unit and a memory, and the memory stores a YOLOv5 model;

[0010] When the video monitoring control switch is closed, the central processing unit calls the YOLOv5 model in the memory to perform human body detection and judgment on the video image information obtained by the camera.

[0011] A further improvement of this technical solution is that the central processing unit adopts a dual-core central processing unit with a model of i5-6200U.

[0012] A further improvement of this technical solution is the fuel level sensor of the liquid level sensor PY201F.

[0013] A further improvement of the technical solution is that the fuel filling flow meter adopts a fuel filling flow meter with model YH1801TC.

[0014] The beneficial effects of the present invention are:

[0015] Improved fuel bunkering safety: By integrating a fuel flow meter and level sensor, the system accurately monitors flow rate changes and tank level changes during the fuel filling process in real time. This real-time monitoring effectively prevents the generation and accumulation of static electricity caused by excessive filling speeds, reduces the risk of fire or explosion caused by static discharge, and significantly improves the safety of fuel bunkering operations.

[0016] Improved operational efficiency and management: The data collection box is designed for easy installation and maintenance. It is mounted near the fuel tank on a guide rail, reducing wiring complexity and maintenance costs. The system also supports the simultaneous collection and transmission of multiple parameters (such as flow and liquid level), providing comprehensive data support to the control console. This allows operators to quickly understand fueling status and respond promptly to abnormal situations, improving fueling efficiency and overall management.

[0017] In addition, the utility model has a reliable design principle, a simple structure and a very broad application prospect.

[0018] It can be seen that compared with the prior art, the present invention has outstanding substantial features and significant progress, and the beneficial effects of its implementation are also obvious. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0023] like Figure 1 As shown, the utility model provides a tugboat auxiliary fuel filling system, including a fuel filling application all-in-one machine and several data acquisition boxes, the data acquisition boxes are installed at the fuel tank of the fuel filling application all-in-one machine through guide rails (the guide rails here refer to mounting brackets), each data acquisition box is provided with an air switch, a terminal block, a transformer, a router, a first data collector and a second data collector, the first end of the air switch is connected to an external power supply, the second end of the air switch is connected to the input end of the transformer through the terminal block, the router, the first data collector and the second data collector are all connected to the output end of the transformer, the first end of the first data collector is connected to a fuel filling flow meter through the terminal block, the fuel filling flow meter is installed at the fuel filler of the fuel filling application all-in-one machine, the first end of the second data collector is connected to a liquid level sensor through the terminal block, the liquid level sensor is installed in the fuel tank of the fuel filling application all-in-one machine, the second end of the first data collector and the second end of the second data collector are both connected to the console of the fuel filling application all-in-one machine through the router. Among them, the fuel level sensor is PY201F, and the fuel filling flow meter adopts the fuel filling flow meter model YH1801TC.

[0024] In order to facilitate the crew to know the abnormal situation of fuel filling in time, the fuel filling system is also equipped with an alarm. The alarm is connected to the console of the fuel filling application all-in-one machine. When the fuel filling flow exceeds the preset flow threshold, the alarm will be activated to sound an alarm, so that the crew can make timely adjustments.

[0025] In addition, in order to further ensure the safety of the fuel filling process, crew members are prohibited from smoking near the fuel filling application machine. In order to monitor the crew members in real time, the fuel filling system is also equipped with a video monitoring control switch and at least one camera. The camera is connected to the console of the fuel filling application machine through the video monitoring control switch to obtain the crew members' work status, determine whether the crew members are smoking based on human body detection, and activate the alarm when it is determined that the crew members are smoking, and display the video images of the crew members smoking through the console of the fuel filling application machine.

[0026] Specifically, the control console of the fuel filling application machine includes a central processing unit and a memory, and the memory stores the YOLOv5 model; when the video monitoring control switch is closed, the central processing unit calls the YOLOv5 model in the memory to perform human body detection and judgment on the video image information obtained by the camera.

[0027] Among them, the central processing unit uses a dual-core central processing unit model i5-6200U, including 2 USB ports, a 256GB solid-state drive, a 24-inch touch screen (aspect ratio of 16:9, resolution of 1080P), an Ethernet port (RJ45 100M / 1G adaptive) and a power supply (24V DC input voltage). Its power consumption ranges from 35W to 80W.

[0028] In addition, the fuel filling application all-in-one machine in the fuel filling system is also connected to an external data storage server. The data storage server includes 8 hard disk slots, each with a 4TB mechanical hard disk. It is used to store the operating data of the tugboat fuel filling process collected by data acquisition devices such as liquid level sensors and fuel filling flow meters, which is convenient for subsequent inquiries.

[0029] To facilitate communication, the data collection box is equipped with a serial port server, which connects to a router, which in turn communicates with the fuel dispenser. The serial port server includes an Ethernet (RJ45) port and an RS-232 / 422 / 485 port. Each data collection box is equipped with 12 serial ports, 8 network ports, and a standard ground wire. The router is equipped with an external antenna and eight RJ45 100M / 1000M adaptive Ethernet ports. The fuel dispenser system supports Modbus TCP, Modbus RTU, NMEA0183, and TCP / IP protocols.

[0030] The fuel filling system monitors the fuel filling flow rate in real time during the fuel filling process through the fuel filling flow meter, and activates the alarm when the monitored fuel filling flow rate exceeds the preset flow threshold. Specifically, when the flow rate exceeds 70m 3 / h and issue an early warning to slow down the refueling speed; at the same time, the fuel liquid level in the fuel tank in the fuel tank is monitored in real time through the liquid level sensor. When the fuel liquid level is less than or equal to the preset first liquid level threshold, the fuel filling application integrated machine automatically fills the fuel tank in the fuel tank, and when the fuel liquid level is greater than or equal to the preset second liquid level threshold, the fuel filling application integrated machine stops filling fuel into the fuel tank. Specifically, when refueling is carried out, an early warning is issued when the volume of oil corresponding to the collected fuel liquid level exceeds 80% of the tank capacity, and an alarm is issued when it exceeds 90%; when the volume of oil corresponding to the collected fuel liquid level is lower than 40% of the tank capacity, the fuel filling application integrated machine automatically refuels.

[0031] The above disclosure is only a preferred embodiment of the present invention, but the present invention is not limited thereto. Any non-creative changes that can be thought of by technicians in this field, as well as several improvements and modifications made without departing from the principles of the present invention, should fall within the scope of protection of the present invention.
