Description

Technical Field

[0001] This utility model belongs to the field of lubrication equipment technology, specifically relating to an online detection device for gearbox lubricating oil. Background Technology

[0002] It is known that after a period of use, the viscosity, temperature, density, saturation, water content, contamination level, and metal abrasive particles of the internal lubricating oil in gearboxes will change. The lubricating oil quality deteriorates irreversibly, reducing its lubrication effect and affecting the normal operation of the gearbox. To ensure continuous lubrication, it is necessary to regularly test the lubricating oil in the gearbox and replace any that does not meet the requirements in a timely manner. Previously, lubricating oil testing required extracting it and taking it to a laboratory, which wasted manpower and resources.

[0003] Patent application CN202223137999.3 discloses an online monitoring device for lubricating oil in wind turbine gearboxes, comprising a housing, a main unit, a connection port, side plates, and a top cover. The main unit is fixedly installed inside the housing, and the connection port is fixedly installed at the bottom of the housing. Compared to traditional wind turbine gearbox testing devices, this device can automatically and stably perform periodic sampling and testing of the lubricating oil inside the gearbox, eliminating the need for manual extraction and saving significant working time. Furthermore, it allows for remote observation of the device's data and status, enabling remote monitoring and making the device more convenient to use and improving testing efficiency. However, this device can only test the lubricating oil and cannot automatically replace substandard lubricating oil, still requiring manual replacement. The disposal of the replaced substandard lubricating oil is also inconvenient. Utility Model Content

[0004] To address the problems mentioned in the background, this utility model provides an online detection device for gearbox lubricating oil, which can detect the lubricating oil in the gearbox in real time and automatically classify, collect, and process unqualified lubricating oil, thereby improving detection efficiency.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] An online testing device for gearbox lubricating oil includes a testing box, an explosion-proof junction box and an oil drain pipe device on the testing box, an oil tank device at the lower end of the testing box, a testing device inside the testing box, the testing device being connected to the oil drain pipe device, a first oil chamber, a second oil chamber and a third oil chamber inside the oil tank device, the lower end of the oil drain pipe device being connected to the first oil chamber, the testing device being connected to the third oil chamber, a filter device being installed in the first oil chamber, and the output end of the filter device being connected to the second oil chamber.

[0007] As a further provision of the above scheme, the detection device is connected to an input capillary oil circuit, the other end of which is connected to an oil discharge pipe device. A first ball valve is installed on the input capillary oil circuit. The detection device is connected to an output capillary oil circuit, a second ball valve is installed on the output capillary oil circuit, and the output capillary oil circuit is connected to a third oil chamber.

[0008] As a further feature of the above scheme, a solenoid valve is provided at the lower end of the connection between the oil drain pipe device and the input capillary oil circuit. The solenoid valve is electrically connected to the detection device and can automatically control the opening and closing of the oil drain pipe device.

[0009] As a further feature of the above scheme, a filter inclined plate is provided at the upper end of the first oil chamber. The filter inclined plate is located above the filter device, and a cleaning window is provided at the side plate of the detection box on one side of the filter inclined plate.

[0010] As a further provision of the above scheme, a first oil drain valve is provided on the bottom plate of the first oil chamber, a second oil drain valve is provided on the bottom plate of the second oil chamber, and a third oil drain valve is provided on the bottom plate of the third oil chamber. A level gauge is provided on the front of the first oil chamber, the second oil chamber, and the third oil chamber.

[0011] This utility model has the following beneficial effects:

[0012] During operation, the solenoid valve is normally closed. Opening the first and second ball valves allows a continuous flow of small amounts of lubricating oil into the detection device via the drain pipe and input capillary oil path. The detection device monitors the lubricating oil in the gearbox in real time. After monitoring, the lubricating oil is discharged into the third oil chamber via the output capillary oil path. The third oil chamber collects qualified lubricating oil for subsequent recycling. When the lubricating oil is unqualified, the solenoid valve opens, and the lubricating oil in the gearbox is discharged into the first oil chamber via the drain pipe. At the same time, the lubricating oil in the input capillary oil path also automatically flows into the first oil chamber. After preliminary treatment by the filter plate, the oil is further processed by the filter before being input into the second oil chamber. This device can monitor the lubricating oil in the gearbox in real time, automatically classifying and processing unqualified lubricating oil, greatly improving detection efficiency.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-3 This application will be described in detail with reference to the embodiments.

[0019] like Figure 1 , Figure 2 As shown, an online testing device for gearbox lubricating oil includes a testing box 1 equipped with an explosion-proof junction box 101 and an oil drain pipe device 4. An oil tank device 2 is located at the lower end of the testing box 1. A testing device 3 is installed inside the testing box 1 and is connected to the oil drain pipe device 4. The oil tank device 2 contains a first oil chamber 201, a second oil chamber 202, and a third oil chamber 203. The lower end of the oil drain pipe device 4 is connected to the first oil chamber 201, and the testing device 3 is connected to the third oil chamber 203. A filter device 5 is installed inside the first oil chamber 201, and the output end of the filter device 5 is connected to the second oil chamber 202.

[0020] like Figure 1 , Figure 3 As shown, the detection device 3 is connected to an input capillary oil passage 301, the other end of which is connected to the oil drain pipe device 4. A first ball valve 3011 is installed on the input capillary oil passage 301. The detection device 3 is connected to an output capillary oil passage 302, which is equipped with a second ball valve 3021. The output capillary oil passage 302 is connected to the third oil chamber 203. A solenoid valve 401 is installed at the lower end of the connection between the oil drain pipe device 4 and the input capillary oil passage 301. The solenoid valve 401 is electrically connected to the detection device 3 and can automatically control the opening and closing of the oil drain pipe device 4.

[0021] A filter inclined plate 2011 is provided at the upper end of the first oil chamber 201. The filter inclined plate 2011 is located above the filter device 5.

[0022] The working process of this utility model is as follows: When the equipment is working, the solenoid valve 401 is in the normally closed state, and the first ball valve 3011 and the second ball valve 3021 are opened. A small amount of lubricating oil is continuously input into the detection device 3 through the oil drain pipe device 4 and the input capillary oil 301. The detection device 3 performs real-time detection of the lubricating oil in the gearbox. After the detection is completed, the lubricating oil is discharged into the third oil chamber 203 through the output capillary oil path 302. The third oil chamber 203 is used to collect qualified lubricating oil for subsequent recycling; unqualified lubricating oil is discharged into the third oil chamber 203. When the gearbox is in operation, the solenoid valve 401 automatically opens, and the lubricating oil in the gearbox is discharged into the first oil chamber 201 through the oil drain pipe device 4. At the same time, the lubricating oil in the capillary oil circuit 301 also automatically flows into the first oil chamber 201 to avoid affecting subsequent testing. After the oil is initially treated by the filter inclined plate 2011, it is collected in the first oil chamber 201. The filter device 5 is activated to further treat the oil before it is input into the second oil chamber 202 for final storage. Finally, the oil is discharged through the first oil drain valve 6, the second oil drain valve 7, and the third oil drain valve 8.
