Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, specifically to a flow distribution device for a wind power lubrication and cooling system. Background Technology

[0002] With the rapid development of renewable energy, wind power has become an important direction for adjusting my country's energy structure. During the operation of wind turbine generator sets, the performance of the lubrication and cooling system directly affects the stable operation and lifespan of the unit.

[0003] The wind turbine lubrication and cooling system mainly consists of two parts: the lubrication system and the cooling system. The lubrication system is responsible for providing lubricating oil to the moving parts of the unit to reduce wear and extend service life; the cooling system is responsible for removing the heat generated by the lubricating oil during operation and keeping the lubricating oil temperature within a reasonable range.

[0004] Traditional flow distribution uses a temperature control valve, which requires periodic maintenance and replacement due to its inherent consumption characteristics. This fails to meet the reliability requirements of the unit and increases operating costs. Therefore, a flow distribution device for a wind power lubrication and cooling system is proposed to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a flow distribution device for a wind power lubrication and cooling system. This device solves the technical problem mentioned in the background section: the traditional flow distribution method using a temperature control valve requires periodic maintenance and replacement due to its inherent consumption characteristics, which fails to meet the reliability requirements of the unit.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flow distribution device for a wind power lubrication and cooling system, comprising:

[0007] An oil outlet is provided at the oil outlet end of the lubrication system. The oil outlet is connected to a first oil passage and a second oil passage arranged in parallel. The other end of the first oil passage and the second oil passage is connected to the device being lubricated.

[0008] An adjustable check valve is provided in the first oil line, and a speed regulating valve connected to the adjustable check valve is also provided at the end of the first oil line near the lubricated device; and

[0009] The cooling system is located on the second oil line.

[0010] In a preferred embodiment, the oil outlet is connected to the first oil circuit and the second oil circuit via a three-way valve.

[0011] In a preferred embodiment, the adjustable check valve includes:

[0012] The valve body is provided with an oil inlet channel and an oil outlet channel connected thereto. The oil inlet channel is connected to the three-way valve, and the oil outlet channel is connected to the speed control valve.

[0013] A valve block is slidably disposed in the valve body along its axis, and one end of the block can block the oil inlet channel.

[0014] A sliding rod slidably passes through the valve block, one end of the sliding rod is provided with an abutment block, and a spring is provided between the abutment block and the valve block; and

[0015] An actuation component, disposed on the valve body, drives the abutment block to slide within the valve body.

[0016] In a preferred embodiment, the propulsion assembly includes a screw plug screwed onto the valve body and abutting against the abutment block.

[0017] In a preferred embodiment, a throttling orifice plate is provided at the connection between the lubricated device and the first oil circuit and the second oil circuit.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This distribution device connects its oil outlet to the oil outlet of the lubrication system. Lubricating oil is discharged through the outlet. When the lubricating oil temperature is low, the pressure of the lubricating oil flowing out of the outlet is high, opening the adjustable check valve. After the flow rate is regulated by the speed control valve, the lubricating oil directly enters the device being lubricated. The speed control valve can automatically adjust to maintain a constant flow rate, achieving a low-temperature flow distribution function. When the lubricating oil temperature is high, the pressure of the lubricating oil flowing out of the outlet is low, and the lubricating oil cannot open the adjustable check valve to directly enter the device being lubricated. Instead, it enters the cooling system, achieving a high-temperature flow distribution function. Furthermore, the adjustable check valve can be adjusted to regulate its opening pressure, effectively controlling the flow distribution of lubricating oil to the cooling system and the device being lubricated. This ensures that high-temperature lubricating oil passes through the cooling system, while low-temperature lubricating oil goes directly to the device being lubricated. Through the cooperation of the adjustable check valve and the speed control valve made of metal, it has a longer service life and more stable control than traditional temperature control valves, eliminating the need for frequent replacements and effectively reducing operating costs.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0026] Example:

[0027] like Figure 1 As shown, this utility model provides a flow distribution device for a wind power lubrication and cooling system, including an oil outlet 1, which is located at the oil outlet end of the lubrication system. The oil outlet 1 is connected to a first oil passage 3 and a second oil passage 6 arranged in parallel. The other end of the first oil passage 3 and the second oil passage 6 is connected to a device to be lubricated 9. An adjustable check valve 4 is provided on the first oil passage 3. A speed regulating valve 5 connected to the adjustable check valve 4 is also provided on the end of the first oil passage 3 near the device to be lubricated 9. A cooling system 7 is provided on the second oil passage 6.

[0028] In use, the distribution device connects oil outlet 1 to the oil outlet of the lubrication system. Oil outlet 1 is connected to the first oil passage 3 and the second oil passage 6 via a three-way valve 2. Lubricating oil flows through the three-way valve 2 into the first oil passage 3 or the second oil passage 6, and then through the first oil passage 3 or the second oil passage 6 to the device being lubricated 9 to lubricate its internal parts. A throttling orifice plate 8 is provided at the connection between the device being lubricated 9 and the first oil passage 3 and the second oil passage 6, which reduces the pressure of the lubricating oil.

[0029] like Figure 1 , 2As shown, in this embodiment, the adjustable one-way valve 4 includes a valve body 41, which is provided with an oil inlet channel 42 and an oil outlet channel 43 connected thereto. The oil inlet channel 42 is connected to the three-way valve 2, and the oil outlet channel 43 is connected to the speed control valve 5. A valve block 46 is slidably disposed inside the valve body 41. One end of the valve block 46 can block the oil inlet channel 42. A sliding rod 44 is slidably disposed inside the valve block 46. One end of the sliding rod 44 is provided with an abutment block 45. A spring 47 is disposed between the abutment block 45 and the valve block 46. A propulsion assembly is also provided on the valve body 41 to drive the abutment block 45 to slide inside the valve body 41. The propulsion assembly includes a screw plug 48, which is screwed onto the valve body 41 and abuts against the abutment block 45.

[0030] The screw plug 48 can be rotated to slide on the valve body 41, thereby pushing the abutment block 45 to slide inside the valve body 41. The movement of the abutment block 45 is positioned by the sliding rod 44. During the movement, the abutment block 45 can compress the spring 47. The spring coefficient of the spring 47 is used to adjust the opening pressure of the one-way valve, ensuring that the opening pressure value can be adjusted in actual application scenarios.

[0031] Based on the characteristics of the lubricating oil, when the oil temperature is low, the pressure of the lubricating oil flowing out from the oil outlet 1 is high. The lubricating oil opens the adjustable check valve 4, and after the flow rate is regulated by the speed regulating valve 5, it directly enters the lubrication point. The speed regulating valve 5 can automatically adjust to always maintain a constant flow rate, thus achieving the low-temperature flow distribution function. When the oil temperature is high, the pressure of the lubricating oil flowing out from the oil outlet 1 is low. The lubricating oil cannot push open the valve block 46 in the adjustable check valve 4 and directly enter the lubricated device 9. Instead, it can only enter the cooling system 7, where the lubricating oil is cooled, thus achieving the high-temperature flow distribution function.

[0032] The specific usage and beneficial effects of this utility model are as follows:

[0033] The distribution device connects its oil outlet 1 to the oil outlet of the lubrication system. Lubricating oil is discharged through oil outlet 1. When the lubricating oil temperature is low, the pressure of the lubricating oil flowing out of oil outlet 1 is high, and the lubricating oil opens the adjustable one-way valve 4. After the flow rate is regulated by the speed regulating valve 5, the lubricating oil directly enters the device being lubricated 9. The speed regulating valve 5 can automatically adjust to always maintain a constant flow rate, realizing the low-temperature flow distribution function. When the lubricating oil temperature is high, the pressure of the lubricating oil flowing out of oil outlet 1 is low, and the lubricating oil cannot open the adjustable one-way valve 4 to directly enter the device being lubricated 9. Instead, it can only enter the cooling system 7, realizing the high-temperature flow distribution function. Moreover, through the setting of the adjustable one-way valve 4, its opening pressure can be adjusted, which can effectively control the flow distribution of lubricating oil to the cooling system 7 and the device being lubricated 9. It ensures that the high-temperature lubricating oil passes through the cooling system 7, and the low-temperature lubricating oil goes directly to the device being lubricated 9. Through the cooperation of the adjustable one-way valve 4 and the speed regulating valve 5 made of metal, it has a longer service life and more stable control than traditional temperature control valves, eliminating the need for frequent replacement and effectively reducing operating costs.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
