Description

Technical Field

[0001] This utility model relates to the field of marine generator control technology, and in particular to an intelligent lubricating oil filling system for generator sets. Background Technology

[0002] In engineering vessels used for projects such as submarine fiber optic cable installation, their electric propulsion systems typically employ marine generator sets. During daily operation, the diesel engines of these generator sets gradually consume lubricating oil, necessitating regular lubrication replenishment. However, existing lubrication replenishment methods present numerous problems.

[0003] Lubricating oil on ships is typically stored in an oil tank, which is connected to the generator set mounting platform via an oil pump and pipelines. A valve is installed at the oil outlet. To add lubricating oil to the generator, operators must first open the outlet valve, collect the oil in a bucket, and then move the bucket to the generator's oil inlet. A funnel is then used to inject the oil into the generator. This method is not only labor-intensive, requiring operators to frequently move heavy buckets filled with oil, but also prone to spillage and waste during handling and injection. Furthermore, these types of engineering vessels are usually equipped with multiple generator sets. For example, fiber optic cable construction vessels typically have four or more generator sets, spaced apart. This means that each generator set needs to be refilled individually based on its oil consumption. The entire refilling process is time-consuming, inefficient, and manual refilling makes it difficult to precisely control the amount of oil added, affecting the generator's lubrication.

[0051] The output end of the oil injection branch is used to connect to the oil injection port of the generator set.

[0052] Each of the aforementioned oil injection branches is equipped with the valve unit.

[0053] As described above, the beneficial effects of this utility model are as follows: The lubricating oil tank is connected to the generator set's oil inlet via an oil pump unit, a valve unit, and oil injection branches. The oil pump unit provides the power for the continuous delivery of lubricating oil, the valve unit controls the start and stop of lubricating oil injection, and the PLC control unit is connected to both the oil pump unit and the valve unit to achieve centralized control of lubricating oil injection. The connection between the lubricating oil tank and the generator set's oil inlet avoids the problems of high labor intensity and oil spillage waste caused by frequent handling of oil drums in traditional methods. The oil pump unit delivers lubricating oil to multiple oil injection branches, each of which is connected to the generator set's oil inlet, enabling the system to simultaneously inject oil into multiple generator sets, greatly improving injection efficiency and reducing the time spent injecting oil into each generator individually. Simultaneously, the valve units on the oil injection branches allow for independent control of the lubricating oil flow in each branch, meeting the lubricating oil injection needs of different generator sets and achieving precise injection. Therefore, this system can automatically add lubricating oil to the generator set, simplifying the adding process and improving adding efficiency.

[0054] Furthermore, the oil pump unit includes an electric oil pump branch, a manual oil pump branch, and a main oil injection line;

[0055] The PLC control unit is connected to the electric oil pump on the electric oil pump branch;

[0056] The oil outlet of the lubricating oil tank is connected to the inlet end of the electric oil pump branch and the manual oil pump branch, respectively.

[0057] The outlet ends of the electric oil pump branch and the manual oil pump branch are connected to the first end of the main oil injection line;

[0058] The second end of the main oil injection line is connected to the input ends of multiple oil injection branch lines.

[0059] As described above, the inclusion of both electric and manual oil pump branches provides two oil filling methods, increasing the system's flexibility and reliability. The electric oil pump enables automated and rapid oil filling operations, improving work efficiency; the manual oil pump serves as a backup in special circumstances such as electric oil pump failure or power outages, ensuring the continuity of the oil filling process, enhancing the system's emergency response capabilities, and further guaranteeing the normal operation of the generator set.

[0073] Furthermore, it also includes oil filters;

[0074] The oil outlet of the lubricating oil tank is connected to the inlet of the oil pump unit through the oil filter.

[0106] The working principle of the intelligent lubricating oil filling system for generator sets in this embodiment is as follows:

[0107] The operator issues an oil injection command to the PLC control unit via the human-machine interface (HMI). The PLC control unit then activates the oil pump unit, drawing lubricating oil from the lubricating oil tank into the pipeline through a suction device. The lubricating oil in the pipeline is first filtered by an oil filter before entering the oil pump unit. Within the oil pump unit, the lubricating oil can be fed into the main oil injection pipeline via a pipeline equipped with an electric oil pump or a pipeline equipped with a manual oil pump. After passing through the main oil injection pipeline, the lubricating oil is then distributed into each branch oil injection pipeline. The operator opens the valve unit on the corresponding branch oil injection pipeline of the generator set requiring oil injection via the PLC control unit, allowing lubricating oil to be added to the corresponding generator set through the branch oil injection pipeline. Simultaneously, the flow acquisition unit on the branch oil injection pipeline and the liquid level acquisition unit within the generator set return the corresponding oil quantity data to the PLC control unit, which displays the oil quantity data through the HMI for the operator to access.

[0108] In summary, this utility model provides an intelligent lubricating oil filling system for generator sets. By directly connecting the lubricating oil tank to the generator set's filling port, it avoids the labor-intensive problems and oil spillage waste caused by frequent handling of oil drums in traditional methods. The oil pump unit delivers lubricating oil to multiple filling branches, each equipped with a valve unit to independently control the flow of lubricating oil, achieving precise filling for different generator sets and improving the flexibility and accuracy of filling. Simultaneously, the multiple filling branches allow the system to simultaneously fill multiple generator sets, greatly improving filling efficiency and reducing the time spent filling each generator individually. Furthermore, the system uses flow and level acquisition units to monitor the filling process in real time, further optimizing management and ensuring precise control of the filling volume and stable equipment operation. The oil filter effectively filters impurities in the lubricating oil, ensuring its cleanliness and reducing wear on internal generator parts. The addition of a pressure gauge monitors the pressure changes of the lubricating oil before and after the oil filter in real time, providing crucial pressure data for the system and ensuring proper filtration and delivery of the lubricating oil. Therefore, this system can automatically add lubricating oil to the generator set, simplifying the filling process and improving filling efficiency.
