[0020] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.
[0021] The utility model discloses a device for cleaning the bearing oil of a generator of a wind turbine generator set. The main structure comprises a fixed bracket 1 arranged below the oil discharge port. The top of the fixed bracket 1 is bent outwardly with a mounting plate, which is fixed by a nut. The fixed bracket 1 is mounted below the oil discharge port. A carrying box 2 is arranged on the fixed bracket 1. An oil collecting liner 3 is movably inserted on the carrying box 2, so that the oil collecting liner 3 can be conveniently removed to clean the oil. A cavity 4 for containing a cleaning agent is also arranged in the carrying box 2. The top of the cavity 4 is open. The carrying box 2 is provided with a The nozzle is a universal nozzle, which is convenient for adjusting the spraying direction. The nozzle is connected to the inside of the cavity 4 through a self-priming pump, and the cleaning agent is sprayed through the nozzle. When the waste oil accumulates at the oil discharge port and causes the temperature to rise and an alarm is sounded, the nozzle automatically sprays the cleaning agent through the pumping of the self-priming pump to clean the oil stains at the oil discharge port, and all the waste oil after cleaning drips into the oil receiving liner 3 for collection and treatment, thereby realizing automatic cleaning and saving manpower and material resources. In addition, after the high temperature alarm of the bearing, it can be cleaned immediately and the high temperature state can be released to ensure the normal power generation of the fan.
[0022] Preferably, the supporting box 2 is slidably connected to the fixed bracket 1, so that the height of the supporting box 2 can be easily adjusted, thereby adjusting the height of the nozzle and the oil collecting liner 3, which is more flexible to use and can better clean and collect the waste oil at the oil discharge port.
[0023] Preferably, a strip groove 5 is provided on the fixed bracket 1, and a bracket 6 is provided at the bottom of the carrying box 2, which can support and fix the carrying box 2 to prevent the carrying box 2 from falling off the fixed bracket 1. A support frame 7 is movably provided on the side of the fixed bracket 1 away from the carrying box 2, and the support frame 7 protrudes to the side away from the fixed bracket 1, and cooperates with the mounting plate mentioned above to separate the fixed bracket 1 from the equipment by a certain distance, ensuring that the positions of the oil receiving liner 3 and the nozzle correspond to the oil drain port, and the support frame 7 and the bracket 6 are connected by fastening bolts passing through the strip groove 5, and the sliding and fixation of the support frame 7 and the bracket 6 in the strip groove 5 are achieved by loosening and tightening the fastening bolts, thereby adjusting the installation height of the carrying box 2 and the oil receiving liner 3.
