Description

Technical Field

[0001] The present invention relates to the technical field of diesel generator sets, in particular to an oil vapor collecting device for a diesel generator set and a diesel generator set. Background Art

[0002] When a diesel generator set is operating for extended periods, the engine oil temperature remains relatively high. This is because the oil is used to lubricate the piston and cylinder, and it is an organic solvent. While removing heat, it also dissolves some diesel particulate matter and incompletely burned diesel. When these impurities accumulate in the oil pan, they are exposed to high temperatures and eventually atomize to form oil vapor, which is then discharged through the oil pan oil vapor pipe. When the diesel generator set is installed in a silent box, oil stains will form within the box over time, typically adhering to the inner walls of the box, fan blades, and radiator. This can lead to fan corrosion and reduced radiator heat dissipation.

[0003] More information related to the above technical solutions can be found in the following documents:

[0004] Patent publication number CN204436525U discloses an oil vapor collection device for a diesel engine used in power generation. The device primarily consists of an oil vapor collection box, a connecting pipe, an oil return pipe, and an exhaust pipe. The oil vapor collection box consists of an oil vapor collection box housing and a partition densely covered with small holes. The box is bolted to the engine crankcase. The upper right side of the box is connected to the connecting pipe, the other end of which is connected to the diesel engine crankcase ventilation pipe. The interface between the connecting pipe and the crankshaft ventilation pipe is secured with a clamp. The lower left side of the box is connected to the oil return pipe, the other end of which is connected to the reserved hole for the oil dipstick tube on the diesel engine cylinder block. The left side of the upper surface of the box is connected to the exhaust pipe. Its beneficial effects include significantly reducing the oil content in the oil vapor discharged from the generator, reducing the risk of oil contamination within the generator set cabin, and optimizing the reliability of the diesel generator set.

[0005] Patent publication number CN102462994A discloses an oil filter comprising an oil inlet and an oil outlet. A filtering device is positioned between the two lines, housing a filter screen. An oil collection pan is mounted below the filter screen, and an oil collection trough is located below the drain outlet of the oil collection pan. This advantageous effect is that the filtered oil impurities are recovered, improving vehicle interior cleanliness.

[0006] In the process of implementing the present invention, the inventors found that the prior art has the following problems:

[0007] The existing technology simply filters the oil vapor through a mesh plate, allowing the particulate matter, sludge, and other impurities contained in the oil vapor to adhere to the plate. The coarsely filtered gas is then discharged, and the oil impurities slowly flow into a collector by gravity. In the existing technology, when the mesh plate is filled with oil vapor impurities while the mesh holes are still in place, the mesh plate's filtering function is ineffective, and the oil vapor is discharged directly into the air through the mesh holes, causing environmental pollution. Internal cleaning is impossible, so when the mesh plate fails, it must be completely replaced. Summary of the Invention

[0008] In view of the above problems, the present application provides an oil vapor collection device and a diesel generator set for a diesel generator set, which are used to solve the technical problem in the prior art that when the mesh plate is full of oil vapor impurities and the mesh holes are still there, the filtering function of the mesh plate becomes ineffective, and the oil vapor will be directly discharged into the air through the mesh holes, causing pollution to the environment; internal cleaning cannot be achieved, so when the mesh plate fails, it can only be replaced as a whole.

[0009] To achieve the above objectives, in a first aspect, the inventors provide an oil vapor collection device for a diesel generator set, comprising:

[0010] The collecting device body comprises a shell and an oil collecting tank, the shell is provided with an oil vapor inlet and an exhaust port, the oil vapor inlet is provided at the top of the shell, the exhaust port is provided at the side of the shell, a filter is provided in the shell, the filter is provided between the oil vapor inlet and the exhaust port, the height of the filter in the vertical direction is higher than that of the exhaust port in the vertical direction, a cleaning pipeline is provided in the shell, the cleaning pipeline is provided below the filter, the shell is detachably provided on the oil collecting tank, two or more nozzles are provided on the cleaning pipeline, the two or more nozzles are respectively facing upward and downward in the vertical direction, a drain outlet is provided at the bottom of the oil collecting tank, and a valve is provided on the drain outlet;

[0011] a cleaning liquid holding tank, the cleaning liquid holding tank being disposed on one side of the collecting device body, the cleaning liquid holding tank being in communication with the cleaning pipeline and being used to provide cleaning liquid to the cleaning pipeline; and

[0012] A water pump, the cleaning liquid holding tank is connected to the water pump through a pipeline, the water pump is connected to the cleaning pipeline through a pipeline, and the water pump provides power for the cleaning liquid.

[0013] Different from the existing technology, the above technical solution is provided with a cleaning pipeline. The cleaning pipeline is below the filter and the oil collecting tank is below the shell. The oil cleaning agent is pumped into the cleaning pipeline inside the shell by a water pump. The filter and the oil collecting tank are cleaned by the nozzle on the cleaning pipeline. The sewage after cleaning can be discharged through the sewage outlet to achieve the cleaning of the inside of the collection device body. When the filter is found to be about to fail or at regular intervals, it can be actively cleaned. There is no need to replace and maintain the entire collection device every time it is full of oil impurities. The service life of the collection device can be effectively extended, and it does not need to be replaced frequently, which is convenient to use.

[0014] As an embodiment of the present invention, the shell includes a top cover and a shell body, the shell is detachably arranged on the shell body, the filter is detachably arranged in the shell, and the cross-sectional shape of the filter is the same as the cross-sectional shape inside the shell.

[0015] In this way, the top cover of the shell can be removed, so that the dense circular hole filter can be replaced or manually cleaned; the cross-sectional shape of the filter is the same as the cross-sectional shape of the inside of the shell, and all gases entering from the oil vapor inlet need to be filtered by the dense circular hole filter before being discharged; the oil impurities filtered out by the dense circular hole filter flow into the oil collecting tank along the inner wall of the shell for collection, which is convenient for use.

[0016] As an embodiment of the present invention, more than two cleaning pipelines are provided in the shell, the two or more cleaning pipelines are arranged in a horizontal direction, and more than two nozzles are provided along the length direction of the cleaning pipelines.

[0017] In this way, more than two cleaning pipes are arranged in a horizontal direction, and more than two nozzles are arranged along the length direction of the cleaning pipes. The nozzles are wide-angle fan-shaped nozzles, and multiple wide-angle fan-shaped nozzles are divided into upward and downward directions, thereby realizing the cleaning of the circular hole filter plate and the inner wall of the shell, which can basically cover every corner of the filter and the oil collecting tank, and improve the cleaning effect of the collection device body.

[0018] As an embodiment of the present invention, an air filter indicator and a pressure alarm are provided on the top cover, and the air filter indicator and the pressure alarm are used to detect the pressure of the air in the shell. The air filter indicator rotates its internal color indicator card according to the different pressures. When the pressure of the air in the shell exceeds a preset value, the pressure alarm sounds an alarm.

[0019] In this way, an air filter indicator is provided on the top cover, which can physically display the pressure within the housing. When the dense circular hole filter is clogged, the air pressure within the housing increases, which can be sounded by the pressure alarm, reminding the operator to clean the filter. This prevents the risk of damage to the collection device due to increased internal pressure caused by the dense circular hole filter being clogged. Specifically, the pressure sensor feeds back the current pressure value within the container to the controller via an electrical signal. When the pressure value exceeds the controller's preset alarm value, the controller will alarm.

[0020] As an embodiment of the present invention, the cleaning liquid holding box is a detachable oil collecting pan, and the detachable oil collecting pan and / or the inner wall of the shell are provided with a Teflon material layer.

[0021] In this way, the cleaning liquid holding box is a detachable oil collecting pan, and the inner wall of the oil collecting pan is lined with a Teflon material layer. Teflon is non-sticky and moisture-resistant, which makes it easy for oil vapor impurities or cleaning agents to clean the oil collecting pan; its heat resistance and corrosion resistance can well cope with the high temperature of oil vapor and the corrosiveness of oil impurities; its wear resistance and safety ensure the service life and environmental friendliness of the oil collecting pan.

[0022] As an embodiment of the present invention, a transparent oil mark window is provided on the oil collecting tank.

[0023] In this way, impurities and sludge in the oil collecting tank can be observed through the transparent oil mark window, making it convenient to observe the usage of the oil collecting tank.

[0024] As an embodiment of the present invention, a first liquid level sensor is provided on the oil collecting tank, and the height of the first liquid level sensor in the vertical direction is higher than the height of the transparent oil mark window in the vertical direction. The oil vapor collection device for the diesel generator set also includes a controller. The first liquid level sensor is electrically connected to the controller and sends liquid level data to the controller. The controller controls the water pump according to the data sent by the first liquid level sensor.

[0025] In this way, when the first liquid level sensor detects the height of impurities and sludge in the oil collecting tank and the oil level reaches a high level, an alarm is issued. The operator starts cleaning or the controller automatically starts cleaning. The water pump can be automatically turned on to clean the filter and the oil collecting tank, realizing automatic monitoring and control.

[0026] As an embodiment of the present invention, a second liquid level sensor is provided on the shell, and the height of the second liquid level sensor in the vertical direction is lower than the height of the exhaust port in the vertical direction. The second liquid level sensor is electrically connected to the controller and sends liquid level data to the controller. The controller also controls the water pump according to the data sent by the second liquid level sensor.

[0027] In this way, when the cleaning agent cleans the inside of the shell, the second liquid level sensor detects that the cleaning liquid level has reached a preset height, which is lower than the vertical height of the exhaust port. The water pump is stopped and an alarm is sounded, thereby preventing the cleaning liquid from filling the collector too much. At the same time, because the exhaust port is lower than the oil vapor inlet, even if the second liquid level sensor fails, the cleaning liquid will only flow out of the exhaust port and will not flow back into the diesel generator set due to overfilling. This achieves physical protection of the diesel engine when the electronic signal fails. In a further solution, the cleaning liquid flowing out of the exhaust port can be connected to the outside of the diesel generator set through a pipe to prevent sewage from contaminating the diesel generator set. The exhaust port is connected to the outside of the engine body through a pipe, and the exhaust gas can also be discharged to the outside of the engine body through the pipe. After being collected, the oil vapor will not cause harm to the fan or radiator.

[0028] As an embodiment of the present invention, the controller is further configured to control the valve according to data sent by the second liquid level sensor.

[0029] In this way, once the second liquid level sensor detects that the cleaning liquid level has reached a preset height, it can directly control the valve to discharge the wastewater into the oil collection tank, thus achieving fully automated control of the cleaning process and improving cleaning efficiency. In a specific embodiment, once the second liquid level sensor detects that the cleaning liquid has reached a preset level, it can first sound an alarm. Upon hearing the alarm, the operator can actively operate the valve to open and drain the wastewater. After the alarm has expired for a specified period of time, if no one is operating the valve, the controller can actively control the valve to open, allowing the wastewater to flow through the pipe into the sewage tank.

[0030] To achieve the above objectives, in a second aspect, the inventor provides a diesel generator set, comprising an oil vapor collection device for a diesel generator set as described in any one of the above items.

[0031] Different from the prior art, the diesel generator set of the technical solution of the present application is provided with a cleaning pipeline. The cleaning pipeline is located below the filter and the oil collecting tank is located below the shell. The oil cleaning agent is pumped into the cleaning pipeline inside the shell by a water pump. The filter and the oil collecting tank are cleaned by the nozzle on the cleaning pipeline. The sewage after cleaning can be discharged through the sewage outlet to achieve the cleaning of the inside of the collection device body. When the filter is found to be about to fail or at regular intervals, it can be actively cleaned. There is no need to replace and maintain the entire collection device every time it is filled with oil impurities. The service life of the collection device can be effectively extended, and there is no need for frequent replacement, which is convenient to use.

[0064] Existing technology simply filters oil vapor through a mesh plate, allowing impurities such as particulate matter and sludge contained in the oil vapor to adhere to the plate. The coarsely filtered gas is then discharged, and the oil impurities slowly flow into a collector by gravity. In existing technology, when the mesh plate is filled with oil vapor impurities while the mesh holes are still in place, the plate's filtering function is ineffective, and the oil vapor is discharged directly into the air through the mesh holes, polluting the environment. Internal cleaning is impossible, so when the mesh plate fails, it must be completely replaced. When the mesh plate fails, there is no effective feedback to the operator to repair or replace the collection device.

[0065] The applicant has found that a cleaning pipeline can be set up inside the shell. The cleaning pipeline is below the filter and the oil collecting tank is below the shell. The oil cleaning agent is pumped into the cleaning pipeline inside the shell by a water pump. The nozzle on the cleaning pipeline sprays high pressure in both the upper and lower directions to clean the filter and the oil collecting tank. The sewage after cleaning can be discharged through the sewage outlet to achieve the cleaning of the inside of the collection device body. Therefore, there is no need to frequently replace or repair the collection device. When the filter is found to be about to fail or every other time, it can be actively cleaned. There is no need to replace and maintain the entire collection device every time it is filled with oil impurities. The service life of the collection device can be effectively extended and convenient to use. At the same time, the air filter indicator and pressure alarm can be used. When the mesh plate fails and the filter mesh is blocked, the air pressure will increase significantly when the shell is ventilated. When it reaches a certain value, it is necessary to alarm through the pressure alarm and actively clean or repair it.

[0066] The oil vapor collecting device for a diesel generator set and the diesel generator set in this embodiment can be applied to various usage occasions of the diesel generator set.

[0067] According to some embodiments of this application, please refer to Figures 1 to 8 , This embodiment relates to an oil vapor collection device for a diesel generator set, including a collection device body 1, a cleaning liquid holding tank 2 and a water pump 3. The collection device body 1 includes a shell 11 and an oil collecting tank 12. The shell 11 is provided with an oil vapor inlet 13 and an exhaust port 14. The oil vapor inlet 13 is arranged at the top of the shell 11, and the exhaust port 14 is arranged at the side of the shell 11. A filter 15 is provided in the shell 11, and the filter 15 is arranged between the oil vapor inlet 13 and the exhaust port 14. The height of the filter 15 in the vertical direction is higher than that of the exhaust port 14 in the vertical direction. A cleaning pipeline 16 is provided in the shell 11, and the cleaning pipeline 16 is arranged below the filter 15. The shell 11 is detachably mounted on the oil collecting tank 12. The cleaning pipeline 16 is provided with two or more nozzles 161, and the two or more nozzles 161 face upward and downward in the vertical direction respectively. A drain outlet 17 is provided at the bottom of the oil collecting tank 12, and a valve 171 is provided on the drain outlet 17.

[0068] The cleaning liquid holding tank 2 is arranged on one side of the collection device body 1. The cleaning liquid holding tank 2 is connected to the cleaning pipeline 16 and is used to provide cleaning liquid to the cleaning pipeline 16; the cleaning liquid holding tank 2 is connected to the water pump 3 through the pipeline 31, and the water pump 3 is connected to the cleaning pipeline 16 through the pipeline 31. The water pump 3 provides power for the cleaning liquid.

[0069] In this embodiment, the collection device body 1, cleaning fluid storage tank 2, and water pump 3 are all located below an exhaust fan 4, which dissipates heat from the diesel generator set. The oil vapor pipe from the diesel generator set's oil pan is connected to the oil vapor inlet 13, allowing the oil vapor to pass through the collection device body 1 before being exhausted. In this embodiment, the treated gas is discharged through the exhaust port 14 and can be directly discharged from the diesel generator set housing 11 through the pipe 31 or drawn away by the exhaust fan 4.

[0070] In this embodiment, the collection device body 1 and the cleaning liquid container 2 are both made of sheet metal. The cleaning agent needs to be added to the cleaning liquid container 2 before use. The water pump 3 is a conventional water pump 3 for pumping the cleaning liquid, and its details are not repeated here.

[0071] In this embodiment, during installation, the oil collecting tank 12 is first bolted to the bottom of the diesel generator housing. The housing body 112 of the collection device body 1 is then bolted to the oil collecting tank 12. The top cover 111 is then bolted to the housing body 112. Gaskets are provided between the oil collecting tank 12, the housing body 112, and the top cover 111 to provide a seal with each other, thus achieving a detachable connection between the oil collecting tank 12, the housing body 112, and the top cover 111.

[0072] In this embodiment, a cleaning pipe 16 is provided, the cleaning pipe 16 is below the filter 15, and the oil collecting tank 12 is below the shell 11. The oil cleaning agent is pumped into the cleaning pipe 16 inside the shell 11 through the water pump 3. The filter 15 and the oil collecting tank 12 are cleaned through the nozzle 161 on the cleaning pipe 16. The sewage after cleaning can be discharged through the sewage outlet 17 to achieve the cleaning of the inside of the collection device body 1; when it is found that the filter 15 is about to fail or at a certain time, it can be actively cleaned. There is no need to replace and maintain the entire collection device every time it is full of oil impurities. The service life of the collection device can be effectively extended, and it does not need to be replaced frequently, which is convenient to use.

[0073] According to some embodiments of the present application, optionally, the shell 11 includes a top cover 111 and a shell body 112, the shell 11 is detachably set on the shell body 112, and the filter 15 is detachably set inside the shell 11, and the cross-sectional shape of the filter 15 is the same as the cross-sectional shape inside the shell 11.

[0074] In this embodiment, the filter 15 is detachably mounted on the inner wall of the housing 11. A fixing portion may be provided on the inner wall of the housing 11, and the filter 15 is placed on the fixing portion so that the filter 15 is stuck on the inner wall of the housing 11. The filter 15 is a densely packed circular hole filter 15, which is covered with circular through holes.

[0075] In this way, the top cover 111 of the shell 11 is detachable, so that the dense circular hole filter 15 can be replaced or manually cleaned; the cross-sectional shape of the filter 15 is the same as the cross-sectional shape inside the shell 11, and all gases entering from the oil vapor inlet 13 need to be filtered by the dense circular hole filter 15 and then discharged; the oil impurities filtered out by the dense circular hole filter 15 flow into the oil collecting tank 12 along the inner wall of the shell 11 for collection, which is convenient for use.

[0076] According to some embodiments of the present application, optionally, more than two cleaning pipelines 16 are provided in the shell 11 , the more than two cleaning pipelines 16 are arranged in a horizontal direction, and more than two nozzles 161 are provided along the length direction of the cleaning pipeline 16 .

[0077] In this embodiment, at least four wide-angle fan-shaped nozzles 161 are provided on the cleaning line 16. The cleaning line 16 is axially rotatable. During the cleaning process, the high pressure causes the rotation to facilitate cleaning of the filter 15 and the oil collection tank 12 in both the upper and lower directions. This principle is similar to that of a dishwasher. The cleaning line can also be fixed, using two or more cleaning lines, each equipped with four or more wide-angle fan-shaped nozzles 161, to substantially cover every corner of the filter 15 and the oil collection tank 12.

[0078] In this way, more than two cleaning pipes 16 are arranged in a horizontal direction, and more than two nozzles 161 are arranged along the length direction of the cleaning pipe 16. The nozzles 161 are wide-angle fan-shaped nozzles 161. Multiple wide-angle fan-shaped nozzles 161 are divided into two directions, upward and downward, thereby achieving the cleaning of the circular hole filter screen 15 plate and the inner wall of the shell 11, which can basically cover every corner of the filter screen 15 and the oil collecting tank 12, thereby improving the cleaning effect of the collection device body 1.

[0079] According to some embodiments of the present application, optionally, an air filter indicator 113 and a pressure alarm are provided on the top cover 111. The air filter indicator 113 is used to detect the pressure of the air in the shell 11. When the pressure of the air in the shell 11 exceeds a preset value, the pressure alarm sounds an alarm.

[0080] Specifically, the pressure sensor feeds back the current pressure value in the container to the controller via an electrical signal. When the pressure value exceeds a preset alarm value of the controller, the controller sounds an alarm.

[0081] In a specific embodiment, the pressure alarm includes a pressure sensor 114 and an alarm. The pressure sensor 114 is arranged in the shell 11, and the alarm is electrically connected to the controller. The electronic signal output by the pressure sensor 114 is controlled by the controller to alarm. After the alarm sounds for a period of time, the machine can be shut down directly; at the same time, the pressure sensor 114 is connected to the controller. When the pressure of the air in the shell 11 exceeds the preset value, the water pump can also be controlled by the controller 19 to pass the cleaning fluid into the cleaning pipeline 16 to actively clean the filter 15.

[0082] In this embodiment, the air filter indicator 113 is used for physical display, and the pressure alarm is used for electrical alarm to prevent too much oil mist from completely blocking the filter 15. There is no bypass valve set on the shell 11 above the filter 15. If the filter 15 is blocked, the shell 11 may be filled and exploded due to excessive air pressure.

[0083] In this way, an air filter indicator 113 is provided on the top cover 111. When the dense circular hole filter 15 is blocked, the pressure of the air in the shell 11 increases, and an alarm can be sounded through the pressure alarm to remind the operator that the filter needs to be cleaned to prevent the risk of damage to the collection device body 1 due to the increase in internal pressure after the dense circular hole mesh is blocked.

[0084] According to some embodiments of the present application, optionally, the cleaning liquid holding box 2 is a detachable oil collecting pan, and the detachable oil collecting pan and / or the inner wall of the shell 11 are provided with a Teflon material layer (not shown in the figure).

[0085] In this way, the cleaning liquid holding box 2 is a detachable oil collecting pan, and the inner wall of the oil collecting pan is lined with a Teflon material layer. Teflon has non-stick and moisture-resistant properties, which can make it easy for oil vapor impurities or cleaning agents to clean the oil collecting pan; its heat resistance and corrosion resistance can well cope with the high temperature of oil vapor and the corrosiveness of oil impurities; its wear resistance and safety ensure the service life and environmental friendliness of the oil collecting pan.

[0086] According to some embodiments of the present application, optionally, a transparent oil mark window 121 is provided on the oil collecting tank 12. The transparent oil mark window 121 is made of glass, which is convenient for outsiders to view.

[0087] In this way, impurities and oil sludge in the oil collecting tank 12 can be observed through the transparent oil mark window 121, making it convenient to observe the use of the oil collecting tank 12.

[0088] According to some embodiments of the present application, optionally, a first liquid level sensor 18 is provided on the oil collecting tank 12, and the height of the first liquid level sensor 18 in the vertical direction is higher than the height of the transparent oil mark window 121 in the vertical direction. The oil vapor collection device for the diesel generator set also includes a controller 19. The first liquid level sensor 18 is electrically connected to the controller 19 and sends liquid level data to the controller 19. The controller 19 controls the water pump 3 according to the data sent by the first liquid level sensor 18.

[0089] In this embodiment, the first liquid level sensor 18 can be used to alarm the oil level in the oil collecting tank 12. When the oil level exceeds the preset value, an alarm is first triggered, and then cleaning liquid is pumped into the filter 15 and the oil collecting tank 12 through the water pump 3 to clean the filter 15 and the oil collecting tank 12.

[0090] In this way, when the first liquid level sensor 18 detects that the impurities and sludge in the oil collecting tank 12 have reached a certain height and the oil level has reached a high level, an alarm is issued, and the operator starts cleaning or the controller 19 automatically starts cleaning. The water pump 3 can be automatically turned on to clean the filter 15 and the oil collecting tank 12, thereby realizing automatic monitoring and control.

[0091] According to some embodiments of the present application, optionally, a second liquid level sensor 20 is provided on the shell 11, and the height of the second liquid level sensor 20 in the vertical direction is lower than the height of the exhaust port 14 in the vertical direction. The second liquid level sensor 20 is electrically connected to the controller 19 and sends the liquid level data to the controller 19. The controller 19 also controls the water pump 3 according to the data sent by the second liquid level sensor 20.

[0092] In this embodiment, the liquid level of the housing 11 can be monitored by the second liquid level sensor 20. When the liquid level exceeds a preset value, an alarm is first generated, and then the valve 171 of the sewage outlet 17 is opened to discharge sewage.

[0093] In this way, when the cleaning agent cleans the inside of the shell 11, the second liquid level sensor 20 detects that the cleaning liquid level has reached a preset height, which is lower than the vertical height of the exhaust port 14, and stops the water pump 3, then sounds an alarm, thereby preventing the cleaning liquid from filling the collector too much. At the same time, since the exhaust port 14 is lower than the oil vapor inlet, even if the second liquid level sensor 20 fails, the cleaning liquid will only flow out from the exhaust port 14 and will not flow back into the diesel generator set due to overfilling, thereby realizing physical protection of the diesel engine when the electronic signal fails.

[0094] In a further solution, the cleaning liquid can flow out from the exhaust port 14 and be connected to the outside of the diesel generator set through a pipe to prevent sewage from polluting the diesel generator set. The exhaust port 14 is connected to the outside of the body through a pipe, and the exhaust gas can also be discharged to the outside of the body through the pipe. After being collected, the oil vapor will not cause harm to the fan and radiator.

[0095] According to some embodiments of the present application, optionally, the controller 19 is further configured to control the valve 171 according to data sent by the second liquid level sensor 20 .

[0096] In this embodiment, the valve 171 may be an electronic valve 171. In a specific embodiment, after the second liquid level sensor detects that the cleaning liquid has reached a preset level, an alarm may be sounded. Upon hearing the alarm, the operator may actively operate the valve to open and drain the wastewater. After the alarm has sounded for a specified period of time, if no one operates the valve, the controller may actively control the valve to open, allowing the wastewater to flow through the pipe into the wastewater tank.

[0097] In this way, after the second liquid level sensor 20 detects that the cleaning liquid level has reached a preset height, it can also directly control the valve 171 to discharge the sewage from the oil collecting tank 12, thereby realizing a fully automated cleaning process and improving cleaning efficiency.

[0098] This embodiment also relates to a diesel generator set, comprising any of the above-mentioned oil vapor collection devices for the diesel generator set.

[0099] Different from the prior art, the diesel generator set of the technical solution of the present application is provided with a cleaning pipe 16. The cleaning pipe 16 is below the filter 15, and the oil collecting tank 12 is below the shell 11. The oil cleaning agent is pumped into the cleaning pipe 16 inside the shell 11 through the water pump 3. The filter 15 and the oil collecting tank 12 are cleaned through the nozzle 161 on the cleaning pipe 16. The sewage after cleaning can be discharged through the sewage outlet 17 to achieve the cleaning of the inside of the collection device body 1; when it is found that the filter 15 is about to fail or at regular intervals, it can be actively cleaned. There is no need to replace and maintain the entire collection device every time it is full of oil impurities. The service life of the collection device can be effectively extended, and it does not need to be replaced frequently, which is convenient to use.

[0100] In this embodiment, a sensor uses sensitive and conversion elements to convert specific measured signals into a usable signal according to a specific pattern and output it to meet the requirements of information transmission, processing, recording, display, and control. The sensor can sense physical quantities such as force, temperature, light, sound, and chemical composition, and can convert these quantities into electrical quantities such as voltage and current, or into the on / off state of a circuit, according to specific patterns. A sensor, generally composed of sensitive and conversion elements, is the primary link in achieving automatic detection and automatic control. The function of a sensor is to convert non-electrical quantities into electrical quantities or the on / off state of a circuit, thereby enabling convenient measurement, transmission, processing, and control.

[0101] In this embodiment, the controller receives signals from sensors and controls actuators or units accordingly. The controller is the master device that controls the starting, speed regulation, braking, and reversing of the motor by changing the wiring and resistance values of the main or control circuits in a predetermined sequence. Composed of a program counter, instruction register, instruction decoder, timing generator, and operation controller, it serves as the "decision-making body" that issues commands, effectively coordinating and directing the operations of the entire computer system.

[0102] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present invention. Therefore, based on the innovative concept of the present invention, changes and modifications to the embodiments described herein, or equivalent structural or equivalent process transformations made using the contents of the present invention's specification and drawings, and direct or indirect application of the above technical solutions to other related technical fields, are all included in the scope of patent protection of the present invention.
