Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine generators, in particular to a device for collecting dust and smoke generated when a wind turbine generator brakes. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current.

[0003] When a wind turbine is shut down for emergency, the intense friction between the brake disc and brake pad will produce a large amount of smoke and dust. If the smoke permeates the cabin for a long time, it may accidentally trigger the cabin's fire-fighting system, and the dust (which is conductive) may splash onto other electrical equipment, easily causing equipment failure.

[0004] Therefore, in order to solve the above problems, a device for collecting dust and smoke generated when a wind turbine is braked is proposed. Summary of the invention

[0007] A collecting structure is installed on the outside of the brake disc, and the collecting structure includes a suction fan, which is fixedly installed on the upper side of the brake disc, and the air outlet end of the suction fan is fixedly connected to a sedimentation device, the air inlet end of the sedimentation device is fixedly connected to a suction pipe, the end of the suction pipe is fixedly connected to a wind hood, and the air outlet end of the sedimentation device is fixedly connected to an air outlet pipe.

[0008] Preferably, the brake pad is clamped on the outer side of the edge of the brake disc, and two groups of the brake pads are provided, and the two groups of the brake pads are symmetrically installed at the farthest points of the two groups of brake discs.

[0009] Preferably, two groups of the air suction pipe and the air hood are provided respectively, and the two groups of the air hood are respectively installed on the outsides of the two groups of brake pads.

[0011] Preferably, two groups of the air outlet pipes are provided, and the ends of the two groups of the air outlet pipes are respectively located at positions on the surfaces of the two groups of brake discs away from the brake pads.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model can collect the smoke and dust generated during braking by arranging a collection structure on the outside of the brake disc, thereby avoiding accidental triggering of the fire protection system in the cabin and protecting the electrical equipment in the cabin.

[0013] The utility model is provided with a collecting structure, which can brake the rotating brake disc through the brake pad, start the suction fan, and suck the dust and smoke generated near the brake pad during braking into the precipitation device through the wind hood and the suction pipe, so as to avoid the false triggering of the cabin fire protection system and protect the electrical equipment in the cabin. The precipitation device can precipitate the dust and smoke in the air, and the clean air can be discharged through the air outlet pipe and can be blown on the brake disc surface away from the side of the brake pad, so as to cool the brake disc and avoid the exhausted wind interfering with the dust and smoke extraction effect of the suction pipe and the wind hood, so as to ensure the use experience of the device.

The suction fan 21 is fixedly installed on the upper side of the brake disc 11, and the air outlet end of the suction fan 21 is fixedly connected to a sedimentation device 22, and the air inlet end of the sedimentation device 22 is fixedly connected to a suction pipe 23, and the end of the suction pipe 23 is fixedly connected to a wind hood 24, and the air outlet end of the sedimentation device 22 is fixedly connected to an outlet pipe 25. The collecting structure 2 is arranged on the outside of the brake disc 11, and can collect smoke and dust generated during braking, so as to avoid accidentally triggering the fire protection system in the cabin and protect the electrical equipment in the cabin.

[0023] Furthermore, the brake pad 12 is clamped on the outer side of the edge of the brake disc 11. Two groups of brake pads 12 are provided.

[0025] Furthermore, the air suction pipe 23 is connected to the inside of the wind hood 24, and the wind hood 24 does not contact the brake disc 11.

The clean air discharged from the sedimentation equipment 22 can be discharged to the surface of the brake discs 11 through the air outlet pipes 25 to cool the brake discs 11 and avoid the discharged wind interfering with the dust and smoke extraction effect of the suction pipe 23 and the wind hood 24, thereby ensuring the user experience of the device.

[0027] Working principle: When in use, the rotating brake disc 11 can be braked by the brake pad 12, and the suction fan 21 can be started. The dust and smoke generated near the brake pad 12 during braking can be sucked into the precipitation device 22 through the wind hood 24 and the suction pipe 23, so as to avoid the false triggering of the cabin fire protection system and protect the electrical equipment in the cabin. The precipitation device 22 can precipitate the dust and smoke in the air, and the clean air can be discharged through the air outlet pipe 25, which can be blown on the surface of the brake disc 11 away from the side of the brake pad 12, so as to cool the brake disc 11 and avoid the exhaust wind interfering with the dust and smoke extraction effect of the suction pipe 23 and the wind hood 24, so as to ensure the user experience of the device.
