Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine blades, in particular to a device for collecting rubber particle impurities based on wind turbine blades. Background Art

[0002] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electricity for wind turbines. During the manufacturing process, wind turbine blades are bonded together by two glass fiber reinforced plastic shells. The excess structural adhesive in the bonding process will fall off into rubber particles after the subsequent rotation and deformation of the wind turbine blades, and accumulate in the inner cavity of the wind turbine blades. As the wind turbine blades rotate, they move, causing abnormal noises in the operation of the wind turbine blades. When cleaning and maintaining the rubber particles and impurities generated by wind turbine blades, most of the time, the rubber particles that fall into the root platform are manually cleaned out by opening the inspection cover and entering the inner cavity of the wind turbine blades.

[0003] However, this purely manual cleaning operation collects an uncertain amount of plastic particles each time. Currently, some wind turbine blades are directly equipped with plastic particle collection devices. When the wind turbine blades rotate, the plastic particles enter the collection device, and it is only necessary to pour out the plastic particles in the collection device regularly.

[0004] The patent specification with announcement number CN218493734U discloses a device for collecting rubber particles and impurities based on wind turbine blades, which relates to the technical field of wind turbine blades, including blades, wherein a funnel and a tube are fixedly connected to the root of the upper surface of the blade, the internal volume of the tube is communicated with the internal volume of the funnel, a through groove is opened on the outer surface of the upper end of the tube, a tube cover is hingedly connected to the inner wall of one side of the through groove by a hinge, and a baffle is fixedly connected to the inner wall of the other side of the through groove; through the cooperation of the above structure, the rubber particles and impurities on the upper surface of the blade can be effectively removed, which is convenient for maintenance personnel to clean, reduces the damage rate of equipment, reduces the maintenance cost of equipment, improves the availability of wind turbine units, and ensures the safe and stable operation of wind turbine units.

[0005] However, in the implementation of relevant technologies, it was found that the above-designed device for collecting rubber particles and impurities based on wind turbine blades has the following problems: when the collecting device is collecting rubber particles, the rubber particles enter the tube through the funnel, and the four sides of the funnel need to fit together with the inner cavity of the wind turbine blade, otherwise the rubber particles will be missed, and the existing funnel is not convenient to adjust according to the size of the inner cavity of the wind turbine blade. In view of this, a device for collecting rubber particles and impurities based on wind turbine blades is provided to overcome the above-mentioned defects. Utility Model Content

The end of the expansion sleeve away from the expansion screw rod is connected to the expansion support rod through a pin shaft. The nylon shielding sheet can be expanded through the expansion support rod. After the driving rod is rotated, the expansion screw rod can be driven to rotate through the active bevel gear and the driven bevel gear, thereby pushing the expansion sleeve to move under the action of the screw rod connecting nut, thereby increasing the distance between the expansion support rod and the axis of the center transfer head, so as to facilitate the expansion of the nylon shielding sheet according to the inner cavity size of the wind turbine blade. The expanded nylon shielding sheet fits with the inner cavity of the wind turbine blade at the root of the blade, and the rubber particles can enter the center transfer head through the nylon shielding sheet.

[0008] As a further description of the above technical solution: a collecting tube is connected to one side of the transfer head, and a collecting bin is provided at the end of the collecting tube. The colloid particles in the transfer head can enter the collecting bin through the collecting tube to clean the colloid particle impurities in the transfer head.

[0009] As a further description of the above technical solution: an exhaust fan is arranged inside the collecting bin, and the collecting bin is interconnected with the transfer head through a collecting pipe. The exhaust fan can draw the colloid impurities in the transfer head into the collecting bin, and the colloid impurities in the wind turbine blades can be cleaned without opening the blade root platform of the wind turbine blades.

[0010] As a further description of the above technical solution: one end of the central transfer head is threadedly connected to a connector, and the connector is connected to the nylon shielding sheet through a rotating shaft. When the nylon shielding sheet is unfolded, the end can be rotated on the connector and adjusted synchronously with the different unfolding ranges of the nylon shielding sheet.

[0011] As a further description of the above technical solution: a filter bracket is arranged inside the connector, and a mounting hole is opened inside the filter bracket. The connector and the transfer head form a cavity structure for storing colloidal impurities.

[0012] As a further description of the above technical solution: the driving rod passes through the interior of the mounting hole, and an expansion knob is fixedly installed on the end of the driving rod away from the active bevel gear. Turning the expansion knob can drive the driving rod to rotate, thereby driving the entire expansion mechanism through the driving rod.

[0013] As a further description of the above technical solution: the nylon shielding sheet is a folding structure, and the end of the nylon shielding sheet away from the connecting head is a folding structure. When the nylon shielding sheet is unfolded outward, the folded part can be stretched.

[0014] The utility model has the following beneficial effects:

[0015] The utility model is a device for collecting rubber particles and impurities on wind turbine blades. The device provides a plurality of folded nylon shielding sheets, the ends of which are connected to a connecting head. When in use, the nylon shielding sheets can be unfolded according to the inner cavity size of the wind turbine blade at the root of the blade, so that the nylon shielding sheets form a funnel-shaped structure. The rubber particles on the wind turbine blades can slide along the nylon shielding sheets into the transfer head, and are drawn into the collection bin for collection through a collection pipe provided on the transfer head under the action of an exhaust fan.

[0016] The utility model is a device for collecting rubber particle impurities based on the blades of a wind turbine generator set. By turning the expansion knob, the driving rod can be driven to rotate, thereby rotating the active bevel gear and the driven bevel gear, and driving the expansion lead screw to rotate. Under the action of the lead screw connection nut, the expansion sleeve is pushed to move, thereby increasing the distance between the expansion support rod and the axis of the center rotating head, making it convenient for the nylon shielding sheet to be expanded according to the inner cavity size of the wind turbine blade.
