Abstract
The utility model relates to a yawing lightning protection device of a wind driven generator. The yawing lightning protection device comprises a support connected with a fan rack, a carbon brush sleeve is connected to the support, a carbon brush connected with a lightning protection ground wire is installed in the carbon brush sleeve, the bottom of the carbon brush is in contact with the end face of a yawing brake disc, a reeling constant force spring sheet is arranged at the top of the carbon brush, an inserting groove is formed in the lateral face of the carbon brush sleeve, a V-shaped elastic inserting piece for fixing the reeling constant force spring sheet is installed in the inserting groove, and an abrasion signal sensor is installed on an inserting sheet, connected with the reeling constant force spring sheet, of the V-shaped elastic inserting piece. According to the yawing lightning protection device, the carbon brush can be in effective and reliable contact with the end face of a yawing brake disc through the reeling constant force spring sheet, the abrasion signal sensor can be used for reminding a maintainer to replace the carbon brush, and operation potential safety hazards caused by the fact that the carbon brush is completely abraded or damaged are avoided. The V-shaped elastic inserting piece is used, so that convenience is brought to maintenance, the yawing lightning protection quality and fan operation safety are greatly improved, and the yawing lightning protection device is simple in structure and convenient to disassemble and maintain.
Description
Technical field
The utility model relates to a kind of wind driven generator yaw lighting protection device.
Background technique
The high speed development of wind-driven generator is a performance of global energy problem, wind power generating set is due to the characteristics of its special working environment and height, often become the target of thunderbolt, thunder and lightning is also all the more serious to the threat of wind power generating set, because the average height of wind power generating set is all in the 100m left and right, and be exposed to fully under the environment of lightening activity, and thunder and lightning is the systematic serious Factual Damage that has to the destruction of wind power generating set simultaneously, so we should fully pay attention to grave danger that thunderbolt brings to wind-force wind-powered electricity generation unit and operations staff.
Traditional wind group driftage lighting protection device comprises the carbon brush be fixed on frame, and carbon brush is by the spring assembly maintenance of stretching and contacting of yaw brake disc end face; This simple in structure, but the blower fan long-play very easily causes extension spring fatigue, can't effectively compress carbon brush, finally reduces the lightning protection quality, and blower fan is caused to potential safety hazard, and this device damage Anywhere just need to be by whole part replacement; In addition due to traditional lighting protection device alarm design that do not wear and tear, when carbon brush is damaged or when heavy wear, can not sends in time and safeguard alarm, cause lightning protection to be lost efficacy, bring safely hidden trouble to later maintenance and blower fan.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provide a kind of reliable in quality, simple in structure, easy for installation, be convenient to the wind driven generator yaw lighting protection device of safeguarding.
Technical problem to be solved in the utility model is to realize by following technological scheme, the utility model is a kind of wind driven generator yaw lighting protection device, be characterized in: comprise the support be connected with the blower fan frame, be connected with carbon brush sleeve on support, the carbon brush be connected with the lightning protection line is housed in carbon brush sleeve, touch mutually with the yaw brake disc end face bottom of carbon brush, the top of carbon brush is provided with rolling constant force spring sheet, side at carbon brush sleeve is provided with slot, the fixedly V-arrangement elastic plugin of rolling constant force spring sheet is housed in slot, on the inserted sheet of the V-arrangement elastic plugin joined with rolling constant force spring sheet, the wear signal sensor is housed.
Technical problem to be solved in the utility model can also further realize by following technological scheme, between described support and carbon brush sleeve, is provided with cushion block, can make between support and carbon brush sleeve to realize flexibly connecting.
Technical problem to be solved in the utility model can also further realize by following technological scheme, and described wear signal sensor is micro limit switch.
The utility model can make carbon brush effectively reliably contact with driftage brake end face by rolling constant force spring sheet, uses the wear signal sensor can remind the O&M personnel to change carbon brush, avoids carbon brush abrasion totally or damage the operation caused having potential safety hazard; Use the V-arrangement elastic plugin to make easy to maintenance, compared with prior art, improved greatly driftage lightning protection quality and fan operation safety, and simple in structure, convenient disassembly, be convenient to safeguard.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of V-arrangement elastic plugin.
Embodiment
Referring to accompanying drawing, further describe concrete technological scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not form the restriction to its right.
With reference to accompanying drawing 1 and Fig. 2; a kind of wind driven generator yaw lighting protection device; comprise the support 1 be connected with the blower fan frame; be connected with carbon brush sleeve 4 on support 1; be provided with cushion block between support 1 and carbon brush sleeve 4, the carbon brush 5 be connected with lightning protection line 2 is housed in carbon brush sleeve 4, touch mutually with the yaw brake disc end face bottom of carbon brush 5; effect is that the electric current that thunderbolt is produced guides to the blower fan grounded system by lightning protection line 2, and protection yaw axis bearing assembly is not by broken by lightning.
The top of carbon brush 5 is provided with rolling constant force spring sheet 3, and this spring sheet can guarantee that carbon brush 5 effectively reliably contacts with driftage brake end face.Side at carbon brush sleeve 4 is provided with slot, the fixedly V-arrangement elastic plugin 6 of rolling constant force spring sheet 3 is housed in slot, on the inserted sheet of the V-arrangement elastic plugin 6 joined with rolling constant force spring sheet 3, the wear signal sensor 7 joined with the PLC controller is housed, wear signal sensor 7 is micro limit switch.When carbon brush 5 wearing and tearing arrive certain position, rolling constant force spring sheet 3 shrinks, and when being retracted to the triggering node, wear signal sensor 7 is to PLC controller signal transmission, remind in time the O&M personnel to change carbon brush 5, avoid carbon brush 5 wearing and tearing totally or damage the operation caused having potential safety hazard.
When wear signal sensor 7 damages or rolling constant force spring sheet 3 follows the string while needing to change, only V-arrangement elastic plugin 6 just need to be pulled up and can be changed, reduced greatly maintenance cost.
