Description

Technical Field

[0001] The utility model relates to the technical field of wind power generator sets, in particular to a hydraulic lubrication cooling device for a wind power generator set. Background Art

[0002] A wind turbine generator set consists of a fixed wind rotor at the input end of the generator. It has functions such as the blades rotating under wind power to generate electricity and the generator head rotating. In addition, the lubricating oil installed inside the wind turbine generator set will overheat during long-term use, thus affecting the service life of the equipment.

[0003] Some equipment on the market generally allows the lubricating oil to flow into the filter box through the first infusion pipe. Under the action of the filter screen in the filter box, the impurities rich in it are filtered out, and then the lubricating oil flows through the cooling spiral tube through the first infusion pipe. The heat of the lubricating oil in the cooling spiral tube is exchanged by the seawater in the cooling box, and then flows into the interior of the wind turbine. Through the above operation, the cooling and filtering of the hydraulic lubricating oil body of the wind turbine can be automatically realized.

[0004] However, in actual use of the above equipment, when the equipment operates at high intensity for a long time, the temperature rise rate of the lubricating oil will become faster, which will increase the flow rate of the lubricating oil in the cooling pipe, thereby slowing down the cooling and heat exchange of the lubricating oil, resulting in poor cooling effect of the lubricating oil; in view of this, we propose a hydraulic lubrication cooling device for wind turbines.

[0010] A cooling member is fixedly connected to the top of the inner wall of the installation box, and the cooling member is composed of a U-shaped pipe end fixedly connected to a diverter.

[0011] Preferably, both ends of the cooling element are connected to the oil inlet pipe and the oil outlet pipe respectively, and the cooling element is located at the top center of the inner wall of the installation box, so that the cooling element can perform heat exchange well.

[0012] Preferably, the size of the movable block is matched with the size of the movable groove, and the movable block is arranged inside the movable groove, so that the movable block can move well inside the movable groove.

[0013] Preferably, the position of the protrusion corresponds to the position of the protrusion, and the outer surface of the protrusion contacts the outer surface of the protrusion, so that the filter plate can shake inside the water inlet.

[0016] Compared with the prior art, the utility model provides a hydraulic lubrication cooling device for a wind turbine generator set, which has the following beneficial effects:

[0017] 1. In order to prevent the lubricating oil from not being able to exchange heat well when the flow rate becomes faster, the hydraulic lubricating cooling device of the wind turbine generator set allows the lubricating oil inside the generator set body to enter the cooling element from the oil inlet pipe. The cooling element is composed of a diverter piece fixedly connected to the end of a U-shaped pipe, so that the lubricating oil can be well diverted. At the same time, the motor is started to rotate the fan to allow cold water outside the installation box to enter through the water inlet, so that the cooling element can exchange heat well. When the fan rotates, the convex piece contacts the convex block, and the elastic force of the spring exerts pressure on the movable block, so that the filter plate shakes when it is hit, which can effectively prevent the filter plate from being blocked by scale.

[0018] 2. In order to make the cooling element perform better heat exchange, the hydraulic lubrication cooling device of the wind turbine generator set uses the cold water outside the installation box to enter from the water inlet through the rotation of the fan, so that the cold water entering the installation box contacts the arc surface of the guide plate, and the two guide plates are symmetrically arranged at the center of the cooling element, so that the cold water forms a vortex inside the installation box, so that the cooling element can perform better heat exchange.
