Description

Technical Field

[0001] This invention relates to the field of generator set technology, and more particularly to a diesel generator set power station oil circuit system. Background Technology

[0002] Diesel generator sets, as backup power sources, are widely used in telecommunications, finance and banking sectors, hospitals and schools, factory computer rooms, airports and transportation industries, large shopping malls and public facilities, construction sites, disaster sites, and remote areas with insufficient power, due to their convenient portability, rapid start-up, stable power supply, and strong adaptability. Cabin-type diesel generator power stations are widely used. The generator set is the core component of the cabin-type power generation equipment, while the cabin, as the protective part of the generator set, plays an equally important role. Besides providing protection against rain, wind, sand, and sun exposure, and reducing generator noise, the impact of the ventilation control system within the cabin-type diesel generator power station on the diesel generator set must also be considered. To ensure the fuel supply to the diesel generator set, the fuel level in the fuel tank must be monitored regularly. Diesel generator power stations serve as strategic reserves. In the event of damage or disruption to the main power grid, diesel generator power stations can be supplied with fuel from daily fuel tanks as backup power. However, the amount of fuel that can be held in daily fuel tanks is limited. Furthermore, due to the limited location of the daily fuel tanks in the power station, the size of the daily fuel tanks can be increased. To meet wartime needs and facilitate transportation, this presents new challenges for the application of diesel generator power stations as backup power stations.

[0003] In existing technologies, the fuel system of modular diesel generator sets typically only has a daytime fuel tank with limited fuel capacity, making it difficult to meet the demand for continuous power supply over long periods. Furthermore, the fuel system structure is simple, lacking both manual and electric fuel supply mechanisms, resulting in insufficient reliability. Additionally, traditional fuel system layouts do not fully consider the layered and stacked requirements of modular power stations, leading to insufficiently compact piping arrangements that hinder disassembly, assembly, and transportation.

Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment; other embodiments that conform to the spirit of the present invention may also fall within the scope of the present invention.

[0016] In a preferred embodiment of the present invention, based on the above-mentioned problems existing in the prior art, a diesel generator set power station oil circuit system is provided, such as... Figure 1 As shown, it includes an oil generator layer and an oil tank layer, which are stacked and connected to form a modular power station.

[0017] The generator deck includes a generator compartment A3 and a day fuel tank B. The generator compartment A3 contains a diesel generator set B01, and the day fuel tank B contains a day fuel tank B02.

[0018] The oil tank layer is equipped with an oil tank compartment A4 and an oil pump compartment C. The oil tank compartment A4 contains an oil tank C01, and the oil pump compartment C contains an oil supply pump, which may specifically include a main oil supply pump C17 and a backup oil supply pump C14.

[0019] Oil tank C01 supplies oil to the daily oil tank via the oil supply line and the oil supply pump. The daily oil tank is connected to the oil tank via the oil unloading line. Specifically, the oil supply line includes a main oil supply line and a backup oil supply line. Oil tank C01 supplies oil to the daily oil tank B02 via the main oil supply line and the backup oil supply line, respectively via the main oil supply pump C17 and the backup oil supply pump C14. Each of the main oil supply line and the backup oil supply line includes a manual branch and an electric branch connected in parallel.

[0020] The daily oil tank B02 is connected to the oil tank C01 through the unloading oil circuit. The unloading oil circuit includes a manual unloading branch and an electric unloading branch connected in parallel. The oil in the daily oil tank B02 can flow back to the oil tank C01 through the unloading oil circuit.

[0021] The main oil supply line, backup oil supply line, and unloading oil line are installed between the oil machine layer and the oil tank layer.

[0022] Specifically, in this embodiment, as follows: Figure 1 As shown, the modular power station adopts a modular design, with the generator layer and oil tank layer stacked and connected sequentially from top to bottom or bottom to top. Each layer is quickly assembled and disassembled using standard connectors such as flanges or latches, facilitating transportation and on-site deployment. The generator layer is internally divided into an independent generator compartment A3 and a day-use oil tank B. Generator compartment A3 is used to house and secure the diesel generator set B01, while day-use oil tank B houses the day-use oil tank B02, which provides instantaneous fuel supply to the generator set.

[0023] The oil tank layer is also divided into oil tank compartment A4 and oil pump compartment C. The large-capacity oil tank C01 is located in oil tank compartment A4, while the main oil supply pump C17 and the backup oil supply pump C14 are installed side by side in oil pump compartment C. By setting up an independent large-capacity oil tank C01, the system's oil storage capacity is no longer limited by the space of the generator layer, providing sufficient fuel guarantee for the long-term operation of the diesel generator set B01.

[0024] like Figure 2 As shown, the fuel output from fuel tank C01 is divided into two lines: the main fuel supply line and the backup fuel supply line. In the main fuel supply line, fuel is pressurized by the main fuel supply pump C17 and then delivered to the day fuel tank B02; in the backup fuel supply line, fuel is pressurized by the backup fuel supply pump C14 and then delivered to the day fuel tank B02. The two lines serve as backups for each other. If either fuel line or its pump set fails, the other line can immediately take over the fuel supply task, ensuring the continuity of fuel supply to the diesel generator set B01.

[0025] Specifically, each fuel supply circuit is internally designed with parallel manual and electric branch circuits. Taking the main fuel supply circuit as an example, its electric branch circuit has an electric valve connected in series, enabling automatic or remote control of fuel supply; its manual branch circuit only has a manual valve connected in series, allowing operators to directly open the valve in the manual branch circuit to supply fuel in the event of a control system or power failure. This redundant design balances the convenience of automated operation with reliability under extreme conditions.

[0026] In addition, such as Figure 2 and Figure 4 As shown, when the daily fuel tank B02 needs to be emptied (such as before long-term unit shutdown, maintenance, or transportation), the unloading oil circuit can be opened, and fuel flows back from the daily fuel tank B02 to the lower-level oil tank C01 through the unloading oil circuit. The unloading oil circuit is also equipped with parallel manual unloading branches (containing only manual valves) and electric unloading branches (containing electric valves), providing flexible and reliable unloading options. All oil supply pipelines (main oil supply metal hose B14, backup oil supply metal hose B18) and unloading pipelines (unloading metal hoses B08, C22) connecting the generator layer and the oil tank layer pass through the layer partition, realizing vertical oil circuit continuity and a compact layout.

[0027] In this embodiment, the technical problems of limited fuel reserves, low fuel supply reliability, and inconvenient disassembly and transportation of traditional modular power stations are solved by using a stacked structure and a dual-redundant fuel supply and return design. This significantly extends the continuous power supply time of the power station in off-grid mode and improves the system's battlefield survivability and environmental adaptability.

[0028] Furthermore, it also includes an exhaust silencing layer, an engine layer, an oil tank layer, and an exhaust silencing layer stacked and connected to form a three-layer structure of a modular power station. The exhaust silencing layer includes an exhaust compartment A1 and an air inlet compartment A5, with a silencer A2 installed inside the exhaust compartment A1.

[0029] Specifically, in combination Figure 1 As shown, the exhaust silencing layer is located at the top of the power station, and its interior is divided into an exhaust compartment A1 and an intake compartment A5. High-temperature exhaust gases generated by the diesel generator set B01 during operation, along with hot air from the engine compartment, are discharged through the exhaust compartment A1. A silencer A2 installed inside the exhaust compartment A1 reduces the noise generated by the exhaust airflow. Simultaneously, cool external air enters the lower engine compartment A3 through the intake compartment A5, providing the diesel generator set B01 with the air required for combustion and cooling. The installation of this exhaust silencing layer enables the power station to have excellent air intake and exhaust management and noise reduction capabilities, further optimizing the power station's working environment.

[0030] In another preferred embodiment of the present invention, the main oil supply line passes sequentially from oil tank C01 through oil tank end main oil supply check valve C21, main oil supply Y-type filter C20, oil tank end main oil supply valve C19, main oil supply pump C17, main oil supply metal hose B14 into the oil machine layer, and then through day oil tank end main oil supply check valve B10 to connect to day oil tank B02.

[0031] The backup oil supply line starts from oil tank C01, passes sequentially through oil tank-end backup oil supply check valve C09, backup oil supply Y-type filter C10, oil tank-end backup oil supply valve C11, backup oil supply pump C14, backup oil supply metal hose B18, enters the oil machine layer, and then connects to daily oil tank B02 via backup oil supply check valve B22 at the daily oil tank end.

[0032] The unloading oil line runs from the daily oil tank B02 through the unloading metal hoses B08 and C22 into the oil tank layer and connects to the oil tank C01.

[0033] Specifically, such as Figure 2 , Figure 4 As shown, the specific connection sequence of the main fuel supply line in the tank layer is as follows: It originates from the outlet of tank C01, passes sequentially through the main fuel supply check valve C21 (to prevent fuel backflow into the tank), the main fuel supply Y-type filter C20 (to filter impurities in the fuel and protect downstream pumps and valves), and the main fuel supply valve C19 at the tank end. Then it enters the main fuel supply pump C17. After being pressurized by the main fuel supply pump C17, it connects to the main fuel supply metal hose B14 (which runs through the layer) via the main fuel supply pump outlet metal hose C16, and then enters the fuel dispenser layer. In the fuel dispenser layer, the fuel passes through the main fuel supply metal hose B14, then through the main fuel supply check valve B10 at the day-use fuel tank end, and finally connects to the day-use fuel tank B02.

[0034] The connection sequence of the backup oil supply line is symmetrical: it is led out from oil tank C01, and sequentially passes through oil tank end backup oil supply check valve C09, backup oil supply Y-type filter C10, oil tank end backup oil supply valve C11, and enters backup oil supply pump C14. After being pressurized by backup oil supply pump C14, it passes through backup oil supply pump outlet metal hose C13 and through layer backup oil supply metal hose B18, and in the oil machine layer, it is connected to day oil tank B02 through day oil tank end backup oil supply check valve B22.

[0035] The Y-type filter effectively ensures fuel cleanliness and reduces the risk of pump and valve jamming. The one-way valve ensures the uniqueness of fuel flow, preventing fuel backflow into the fuel tank or pump body due to pressure fluctuations in both the main and backup fuel supply lines, thus ensuring stable fuel supply pressure and system safety.

[0036] The unloading oil circuit is relatively simple: it leads out from the unloading port at the bottom of the daily fuel tank B02, and connects in sequence to the unloading metal hose B08 (located in the oil engine layer), the unloading metal hose C22 after passing through the layer (located in the oil tank layer), and finally connects to the unloading inlet flange C23 of the oil tank C01 to realize fuel return.

[0037] In another preferred embodiment of the present invention, a first main oil supply valve B11, a main oil supply electric valve B12, and a second main oil supply valve B13 are connected in series in the electric branch of the main oil supply circuit, and a third main oil supply valve B15 is connected in series in the manual branch of the main oil supply circuit. The manual branch and the electric branch are connected in parallel.

[0038] The electric backup branch of the backup oil supply circuit is connected in series with a second backup oil supply valve B17, a backup oil supply electric valve B19, and a first backup oil supply valve B20. The manual backup branch of the backup oil supply circuit is connected in series with a third backup oil supply valve B16. The manual backup branch and the electric backup branch are connected in parallel.

[0039] The electric unloading branch of the unloading oil circuit is connected in series with a first unloading valve B04 and an electric unloading valve B06, and the manual unloading branch of the unloading oil circuit is connected in series with a second unloading valve B05. The manual unloading branch and the electric unloading branch are connected in parallel.

[0040] Specifically, this embodiment further details the specific composition of the manual and electric branches in each oil circuit. For example... Figure 2 , Figure 3 As shown, in the main oil supply circuit, the electric branch consists of a first main oil supply valve B11, a main oil supply electric valve B12, and a second main oil supply valve B13 connected in series. During operation, the first main oil supply valve B11 and the second main oil supply valve B13 must first be manually opened. Then, the opening and closing of the main oil supply electric valve B12 is controlled manually or automatically to achieve electric oil supply.

[0041] The manual branch consists of a single third main fuel supply valve B15, which is operated entirely manually. When manual fuel supply is required, simply close the first main fuel supply valve B11 and the second main fuel supply valve B13 (to prevent fuel leakage or backflow through the non-operating electric branch), and then manually open the third main fuel supply valve B15.

[0042] Similarly, the electric branch of the backup oil supply circuit consists of the second backup oil supply valve B17, the backup oil supply electric valve B19 and the first backup oil supply valve B20 connected in series, and the manual branch is the third backup oil supply valve B16.

[0043] The electric unloading branch of the oil unloading circuit consists of the first unloading valve B04 and the electric unloading valve B06 connected in series, while the manual unloading branch is the second unloading valve B05.

[0044] This configuration, by setting up series-connected manual valves (such as the first and second main oil supply valves) in the manual / electric parallel branch, provides physical isolation for the maintenance and replacement of electric valves, improving the safety of system maintenance. At the same time, each branch can operate independently without interference, achieving true full redundancy in oil supply and return control.

[0045] In another preferred embodiment of the present invention, the bottom of the daily oil tank B02 is equipped with a support foot B07, and the lower part of the daily oil tank B02 is also provided with an oil discharge port and a drain valve B03. The oil discharge port is connected to a second oil discharge valve B05. The first oil discharge valve B04 and the oil discharge electric valve B06 are connected in series and then connected in parallel with the second oil discharge valve B05. The oil discharge port passes through the oil discharge metal hose B08 into the oil tank layer and is connected to the oil discharge inlet flange C23 of the oil tank C01.

[0046] Specifically, such as Figure 3 As shown, a drain port is provided at the lowest point of the daily oil tank B02. This drain port is directly connected to the second drain valve, namely the second drain valve B05, which serves as a manual drain branch.

[0047] Simultaneously, the pipeline leading from this unloading port is also connected in parallel to an electric unloading branch consisting of the first unloading valve B04 and the electric unloading valve B06 connected in series. The two branches converge at the unloading port and connect together to the unloading metal hose B08. Fuel passes through the shelf and into the tank layer via the unloading metal hose B08, ultimately connecting to the unloading inlet flange C23 of tank C01. This method of placing the unloading port at the lowest point of the tank utilizes the principle of gravity, ensuring that the fuel in the tank can be emptied to the maximum extent. The parallel manual and electric unloading paths provide operators with multiple options: in daily use, fuel can be unloaded quickly and conveniently via the electric valve; in the event of a power or control system failure, the second unloading valve B05 can be manually opened directly to complete the unloading, ensuring direct and reliable operation.

[0048] In another preferred embodiment of the present invention, the upper part of the daily fuel tank B02 is provided with an inspection port B24, a vented metal hose B23, an emergency refueling valve B25, and an emergency refueling port B26. The upper end of the vented metal hose B23 is connected to a flame arrestor vent cap B21. The side of the daily fuel tank B02 is provided with an overflow flange B09, an oil level gauge B29, a fuel supply valve B31, and a fuel supply metal hose B30. The oil outlet end of the fuel supply metal hose B30 is connected to an oil-water separator B32, and the oil outlet end of the oil-water separator B32 is connected to the oil inlet of the diesel generator set B01 through an oil pipe. The daily fuel tank B02 is also provided with a return port B28 and a drain valve B03. The return port B28 is connected to a return metal hose B27 and connected to the fuel cooler B33 of the diesel generator set B01 through an oil pipe.

[0049] Specifically, this embodiment details the complete structure of the daily fuel tank and its peripheral accessories. For example... Figure 2 , Figure 3As shown, the inspection port B24 on top of the daily fuel tank B02 is used for internal cleaning and maintenance. The vented metal hose B23 and its top flame-arresting vent cap B21 balance the internal and external air pressure of the fuel tank, preventing negative pressure from fuel consumption or positive pressure from temperature increases. Simultaneously, the flame-arresting vent cap B21 effectively prevents external ignition sources from igniting fuel vapors inside the tank. The emergency refueling valve B25 and emergency refueling port B26 constitute an emergency refueling channel. When the main fuel line malfunctions or the fuel level in the tank is insufficient, fuel can be directly added to the daily fuel tank B02 through this port. A fuel level gauge B29 is installed on the side of the tank for real-time monitoring of the fuel level. The fuel supply valve B31 and the fuel supply metal hose B30 constitute the fuel outlet for the diesel generator set B01. After passing through the fuel supply metal hose B30, the fuel first enters the oil-water separator B32 to separate the water from the fuel before being connected to the fuel inlet of the diesel generator set B01 through a pipeline, ensuring the cleanliness of the fuel entering the generator set. The return oil port B28 is located on the upper side of the fuel tank and is connected to the fuel cooler B33 of the diesel generator set B01 via a return oil metal hose B27. The returned oil from the generator set is cooled before flowing back to the day fuel tank B02, forming a circulation system that helps stabilize fuel temperature. The drain valve B03 at the bottom of the fuel tank is used to periodically drain moisture and impurities deposited at the bottom of the tank. The integration of these components makes the day fuel tank B02 a fully functional, safe, and reliable fuel supply unit.

[0050] In another preferred embodiment of the present invention, the oil tank C01 is provided with a level gauge C04, a quick refueling valve C06, a quick refueling port C07, a flame-retardant vent cap C12, an inspection port C08, and a drain valve C02, wherein the quick refueling valve C06 is connected to the quick refueling port C07.

[0051] Specifically, such as Figure 4 As shown, the large-capacity oil tank C01 serves as the main oil storage container. A level gauge C04 is installed on its side to monitor the fuel level inside the tank. A quick refueling interface, consisting of a quick refueling valve C06 and a quick refueling port C07, is located in the upper middle section, facilitating rapid refueling by external fuel trucks. To balance the internal and external air pressure, a flame-arresting vent cap C12 is installed on oil tank C01. An inspection port C08 on the top of oil tank C01 is used for internal inspection and maintenance. A drain valve C02 and two backup valves C03 and C05 (serving as additional vents or drain outlets) at the bottom are used to drain accumulated oil and water from the bottom of the tank or to perform a complete tank emptying. These features make the daily management and maintenance of oil tank C01 simple and efficient.

[0052] In another preferred embodiment of the present invention, the connecting pipelines for the oil supply line and the oil unloading line between the oil machine layer and the oil tank layer are both made of metal hoses.

[0053] Specifically, such as Figure 2 , Figure 3 , Figure 4As shown, all pipelines that need to pass through the partition between the oil pump layer and the oil tank layer, including the main oil supply metal hose B14 in the main oil supply line, the backup oil supply metal hose B18 in the backup oil supply line, and the unloading metal hose B08 (and its extension section C22 in the oil tank layer) in the unloading oil supply line, are made of flexible metal hoses. Using metal hoses effectively absorbs the relative displacement and vibration between layers caused by transportation, installation, or operational vibrations, preventing leakage or breakage due to stress concentration at rigid pipeline connections. Simultaneously, the metal hoses themselves possess pressure resistance, oil resistance, and flame retardant properties, significantly improving the safety and reliability of cross-layer oil circuit connections and making disassembly and separation operations between layers more convenient.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made using the content of this specification and illustrations should be included within the protection scope of the present invention.
