Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic oil supply devices, specifically relating to a vibration-proof and pollution-proof hydraulic oil supply device for wind turbine units. Background Technology

[0002] When wind turbines operate, if the blades rotate too fast, braking is necessary to reduce their speed. Braking is often hydraulically driven, supplied by a brake oil supply system. However, this system lacks shock absorption, shortening the motor's lifespan and increasing operating and repair costs, as well as labor costs. Furthermore, the lack of protective measures between the valve block assembly and the oil tank allows contaminants to easily enter, causing blockages or internal rust, increasing the risk of accidents. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a vibration-proof and pollution-proof hydraulic oil supply device for wind turbines.

[0004] The technical solution adopted to solve the above technical problems is: a vibration-proof and pollution-proof hydraulic oil supply device for wind turbines, including an oil tank assembly, a cover plate fixedly connected to the upper surface of the oil tank assembly, a shock-absorbing pad fixedly connected to the upper surface of the cover plate, and a motor pump assembly and a valve block assembly fixedly connected to the upper surface of the shock-absorbing pad.

[0005] The above technical solution, by setting up a sealed and shock-absorbing layer and a protective sealed and shock-absorbing layer, extends the service life of the motor, reduces the cost of use and repair, reduces labor costs, and prevents contaminants from entering the oil tank, thus eliminating danger.

[0006] Furthermore, connecting plates are fixedly connected to both sides of the fuel tank assembly, and through holes are provided at the lower ends of both sides of the connecting plates.

[0007] The above technical solution can fix the whole unit on the oil collection plate to prevent oil leakage.

[0008] Furthermore, protective plates are fixedly connected to both sides of the cover plate, and the protective plates and the cover plate clamp and fix the shock-absorbing pad.

[0009] The above technical solution can fix and clamp the shock-absorbing pad, preventing it from moving during long-term use.

[0010] Furthermore, the motor pump assembly includes a bell-shaped housing, inside which a drive motor is fixedly connected, and on the upper surface of the shock-absorbing pad, a gear pump is fixedly connected.

[0011] The above technical solution can provide protection for the drive motor and prevent foreign objects from entering.

[0012] Furthermore, an electrical box is fixedly connected to one side of the fuel tank assembly.

[0013] The above technical solution can provide protection for the control circuit board.

[0014] Furthermore, the bottom of the oil tank assembly has several holes, and bolts are threaded into the holes. An oil collection tray is fixedly connected to the end of the bolt away from the oil tank assembly, and a shock-absorbing pad is fixedly connected between the drive motor and the oil tank assembly.

[0015] The above technical solution extends the service life of the motor, and the use of the connecting plate makes the bottom of the oil tank higher than the bottom of the U-shaped connecting plate, thereby providing space for the oil collection tray of the wind turbine nacelle.

[0016] Furthermore, a sealing gasket is provided between the valve block assembly and the cover plate, and the valve block assembly is fixedly connected to the cover plate by bolts.

[0017] The above technical solutions can prevent foreign objects from entering, greatly improving safety.

[0018] The beneficial effects of this utility model are as follows: By setting a sealing and shock-absorbing layer and a protective sealing and shock-absorbing layer, this utility model extends the service life of the motor, reduces the cost of use and repair, reduces labor costs, and prevents contaminants from entering the oil tank, thus eliminating danger.
