[0031] The wind turbine lubrication system is a crucial component of the wind turbine, ensuring the proper functioning of all wind turbine components and extending the life of the equipment. The lubrication system typically consists of a lubricating oil tank, a lubricating oil pump, lubricating oil lines, a lubricating oil filter, a lubricating oil cooler, and lubricating oil nozzles.

[0032] Wind turbines operate in harsh environments, often exposed to high temperatures and humidity. Therefore, the lubrication system is crucial. It effectively prevents problems such as increased friction and increased component wear caused by poor lubrication.

[0033] Proper maintenance of the wind turbine lubrication system can improve equipment operating efficiency, reduce failure rates, lower maintenance costs, and also contribute to environmental protection and resource conservation. The healthy operation of the wind turbine lubrication system is crucial to the normal operation and long-term stable operation of the entire wind power generation system.

[0034] The wind turbine grease filling device is a specialized tool used to add lubricating grease to the lubrication system of a wind turbine. Grease injection is crucial in wind turbines, reducing friction and wear between components, protecting equipment components, and extending the service life of the equipment in harsh environmental conditions.

[0035] A wind turbine grease filling system typically includes a grease gun, grease pump, grease hose, and grease tank. The operator connects the grease hose to the grease gun to precisely fill grease into each lubrication point on the wind turbine, ensuring adequate lubrication for every component. The grease pump provides the necessary pressure to deliver grease to the desired locations, ensuring proper operation of the wind turbine.

[0036] The use of wind turbine grease filling devices helps maintain efficient operation of wind turbines, reduce maintenance costs, and extend equipment life. Regular inspection and maintenance of grease filling devices to ensure their normal operation and good working condition are of great significance to the stability and reliability of wind turbine systems.

[0037] The existing grease filling device only has a program-set regular start-up and filling function, and there is no monitoring of the grease filling amount and filling status. That is, the existing equipment is only responsible for starting the oil pump at the oil supply end, but has no oil monitoring at the oil receiving end and the grease flow process. The integrity of the lubrication system cannot be monitored remotely and intuitively, and a lot of time is required during regular inspection and maintenance to detect the grease filling and lubrication status of each system part of the lubrication system, which is a large workload and time-consuming.

[0038] Therefore, the inventors propose a grease monitoring device for a lubrication system of a wind turbine generator to solve the problem of long daily inspection and maintenance time caused by insufficient monitoring of the grease lubrication system.

[0039] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0040] Figure 1 A schematic diagram of the structure of a grease monitoring device for a wind turbine lubrication system provided in an embodiment of the present application; Figure 2 A diagram showing the usage status of the greasing monitoring device for the lubrication system of a wind turbine provided in an embodiment of the present application; Figure 3 A cross-sectional view of a greasing monitoring device for a lubrication system of a wind turbine provided in an embodiment of the present application; Figure 4 This is a schematic structural diagram of the fasteners of the grease monitoring device of the wind turbine lubrication system provided in an embodiment of the present application.

[0041] Reference Figures 1 to 4 As shown, an embodiment of the present application provides a grease monitoring device for a lubrication system of a wind turbine, comprising: a grease flow sensor 1, a three-way connector 2 and a hose connector 3.

[0042] One end of the hose connector 3 is fixedly connected to the interface of the three-way connector 2, and the other end is plugged and fixed to the grease hose 4 in the lubrication system, so as to connect the three-way connector 2 with the grease hose 4.

[0043] The grease flow sensor 1 is connected to the middle interface of the three-way joint 2 and is used to collect the grease flow in the grease hose 4.

[0044] Specifically, the grease flow sensor 1 is a sensor used to measure the flow rate of lubricating oil or grease. It is used to monitor grease flow to ensure the proper operation of the equipment's lubrication system. The grease flow sensor 1 determines the grease flow rate by measuring the flow rate of grease through the grease hose 4. The grease flow sensor 1 converts the flow rate into an electrical signal output, which can be connected to a monitoring system or display screen for real-time monitoring and data recording.

[0045] The grease flow sensor 1 accurately measures grease flow during use, ensuring data accuracy. It offers stable performance and long-term stability, making it suitable for long-term operating environments. It can withstand the long-term flow of lubricating oil or grease without damage. It is easy to install and disassemble, assemble, and replace. It features high precision, high reliability, wear resistance, and ease of installation.

[0046] Through the monitoring of the grease flow sensor 1, users can understand the flow of grease in real time and detect faults or abnormalities in time, which helps to improve the reliability and efficiency of the equipment and extend the service life of various parts of the wind turbine.

[0047] The three-way joint 2 is a T-shaped joint, in which the two straight joints are used to connect with the grease hose 4, and the vertical joint is fixed to the grease flow sensor 1; the inner diameter of the three-way joint 2 is the same as the inner diameter of the grease hose 4, which is convenient for connecting the three-way joint 2 and the grease hose 4 together to form a sealed pipeline, ensuring that the transported fluid flows smoothly in the pipeline system, and will not cause blockage or leakage due to mismatch of the inner diameter of the pipeline.

[0048] The hose connector 3 can realize quick connection and disassembly of the tee connector 2 and the greasing hose 4 by quick rotation or pushing. The tee connector 2 can be connected to the middle section of the greasing hose 4. The installation can be completed by simply cutting the greasing hose and inserting it to fix it. It is convenient and quick. The tee connector 2 can also be connected between the greasing hose 4 and the greasing equipment; the hose connector 3 is usually composed of a connector body, a connector interface and a seal. Its function is to connect the greasing hose 4 and the tee connector 2 to ensure the normal transmission of the fluid in the pipeline.

[0049] This application connects the grease flow sensor 1 to the grease hose through the three-way connector 2 and the hose connector 3 for flow monitoring, and monitors the grease flow in the grease hose in real time, which can help to timely understand the grease lubrication status of each system part of the lubrication system, achieve precise control and management, effectively extend the service life of each system part of the wind turbine, and improve the reliability and operation efficiency of the wind turbine.

[0050] In some embodiments, the grease monitoring device for the lubrication system of the wind turbine further includes a transparent tube 5 , which is disposed between the hose connector 3 and the tee connector 2 and is used to observe the grease flow inside the grease hose 4 .

[0051] Specifically, the transparent tube 5 is provided between the hose connector 3 and the tee connector 2, allowing the operator to visually observe the flow of grease in the pipe, so as to promptly detect any abnormalities and deal with them. The provision of the transparent tube 5 helps to monitor the operation of the lubrication system and ensure the normal delivery and lubrication effect of the grease. The provision of the transparent tube 5 is conducive to improving the monitoring and management efficiency of the lubrication system, helping to detect problems early and take corresponding measures.

[0052] In some embodiments, the transparent tube 5 is a plastic tube.

[0053] Specifically, the plastic pipe can be made of the following materials:

[0054] PVC (polyvinyl chloride): PVC transparent tube has good transparency and corrosion resistance.

[0055] PETG (Polyethylene Terephthalate): PETG transparent tube has strong heat resistance and toughness.

[0056] PMMA (polymethyl methacrylate, also known as acrylic): PMMA transparent tube has high strength, excellent transparency and heat resistance.

[0057] PC (polycarbonate): PC transparent tube has excellent impact resistance and high temperature resistance.

[0058] The above materials are for illustration only. The specific material of the transparent tube 5 should be selected based on comprehensive consideration of factors such as the actual grease properties and temperature requirements. No specific restrictions are made here. The material selection must ensure the safe and stable operation of the pipeline.

[0059] In some embodiments, the grease monitoring device of the wind turbine lubrication system further includes a fastener 6, which is arranged at the joint of the hose connector 3 and the grease hose 4 to reinforce the joint of the hose connector 3 and the grease hose 4.

[0060] Specifically, the use of fastener 6 ensures a secure connection between hose connector 3 and grease hose 4, preventing tee connector 2 from loosening or falling off during grease flow sensor 1 monitoring. Fastener 6 is relatively simple in structure but effective, providing a secure connection and ensuring greater durability and safety at the connection between hose connector 3 and grease hose 4.

[0061] In some embodiments, the fastener 6 includes a hoop 61 and wing plates 62 provided at both ends of the hoop 61 . Screw holes 63 are provided on the wing plates 62 . The two wing plates 62 are fixed together by bolts 64 that cooperate with the screw holes 63 .

[0062] Specifically, the clamp 61 is the main component connecting the hose connector 3 and the grease hose 4. It is typically made of metal and possesses a certain strength and corrosion resistance. Wings 62, located at each end of the clamp 61, provide support and fixation. Also typically made of metal, they distribute the tightening force and enhance the stability of the fastener 6. Screw holes 63 are defined in the wing 62. Bolts 64 engage with these holes to secure the two wing 62, ensuring that the clamp 61 securely clamps the hose connector 3 and the grease hose 4, preventing them from loosening or falling off.

[0063] In some embodiments, the greasing monitoring device for the lubrication system of the wind turbine further includes a rubber gasket 7 , which is disposed at the connection between the hose connector 3 and the tee connector 2 .

[0064] Specifically, the rubber gasket 7 plays a sealing and buffering role at the connection between the hose connector 3 and the tee connector 2 to ensure the sealing and stability of the connection. The rubber gasket 7 is generally annular and made of rubber or other elastic materials.

[0065] The rubber gasket 7 fills gaps in the joint, effectively preventing grease from leaking from the joint and ensuring the tightness of the piping system. The elasticity of the rubber gasket 7 provides shock absorption and cushioning, reducing vibration and noise during liquid flow or when the pipeline is subjected to external impact, protecting the pipeline from damage. Because the rubber material has a certain degree of elasticity and anti-aging properties, the rubber gasket 7 effectively prevents water leakage or seepage from loosening the joint. The rubber gasket 7 is easy to replace. If the sealing effect is poor or the rubber gasket 7 is damaged, it can be replaced promptly to maintain the tightness of the connection.

[0066] In some embodiments, the middle interface of the three-way joint 2 is provided with an internal thread, the lower end of the grease flow sensor 1 is provided with an external thread matching the internal thread, and the grease flow sensor 1 is threadedly connected to the middle interface.

[0067] Specifically, the grease flow sensor 1 is firmly connected to the intermediate interface by a threaded connection. The design of the internal and external threads can ensure a tight connection while allowing for easy removal and replacement of the grease flow sensor 1.

[0068] The internal and external thread structure design ensures a secure connection between the grease flow sensor 1 and the intermediate interface, preventing loosening or oil leakage, and ensuring a stable and reliable connection between the grease flow sensor 1 and the intermediate interface. When installing the flow sensor, ensure a good fit between the internal and external threads. Use sealant or other materials to enhance the sealing effect and ensure the stability and tightness of the connection.

[0069] In some embodiments, the hose connector 3 is an alloy hose connector 3 .

[0070] Specifically, the alloy hose connector 3 has high strength and hardness, capable of withstanding certain pressures and impacts, ensuring a secure and reliable pipe connection. The alloy material also exhibits excellent corrosion and wear resistance, reducing friction and wear. This allows for long-term, stable use in harsh working environments, extending the service life of the hose connector 3.

[0071] In some embodiments, the hose connector 3 and the three-way connector 2 are detachably connected.

[0072] Specifically, the detachable connection between the hose connector 3 and the tee connector 2 can be achieved by a threaded connection, a ferrule connection, or a quick connector. The detachable connection design facilitates the installation, maintenance, and replacement of the hose connector 3 or the tee connector 2, and improves the convenience and flexibility of operation.

[0073] In some embodiments, the inner diameter of the hose connector 3 is consistent with the inner diameter of the tee connector 2 .

[0074] Specifically, the inner diameter of the hose connector 3 is consistent with that of the tee connector 2 to ensure smooth fluid flow within the piping system, preventing blockages or other problems caused by mismatched pipe diameters. This ensures a tight and stable connection. When the inner diameters of the hose connector 3 and the tee connector 2 are consistent, the connection is tighter, preventing fluid leakage and reducing fluid leakage and pressure loss at the pipe connection. This effectively improves the efficiency and safety of the piping system.

[0075] Those skilled in the art will readily conceive of other implementations of the present application after considering the specification and practicing the technical solutions disclosed herein.

[0076] This application is intended to cover any modifications, uses or adaptations of the present application that follow the general principles of the present application and include common knowledge or customary technical means in the technical field that are not disclosed in this application.
