Description

Technical Field

[0001] The invention relates to a wind power generation blade mould drying device. Background Art

[0002] A wind turbine is an electric device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine generally consists of a wind wheel, a generator (including a device), a stabiliser (tail), a tower, a speed limit safety mechanism and an energy storage device. In the production of wind turbine accessories, such as wind turbine blades, it is necessary to use a blade mold for injection molding and other process flows. Before the blade mold is used to make the blade, the surface of the blade mold must be thoroughly and completely cleaned to prevent the appearance of impurities and bubbles in the produced fan blades, which will cause the fan blades to be scrapped, reworked and of poor quality. For the wet blade mold after cleaning, an efficient drying process is required.

[0014] Beneficial effects of the present invention

[0015] 1. The present invention controls the downward rotation angles of the two rotating telescopic plates respectively, thereby changing the size of the suspended lower space when the blade mold is overlapped on the upper sides of the two rotating telescopic plates. The larger the lower space, the faster the airflow and the better the drying effect. In this way, it can be adjusted according to different drying requirements.

[0016] 2. The present invention realizes two forms of heating modes of the blade mold. When the two rotating telescopic plates rotate downward respectively, the taper of the conical supporting interval with a larger top and a smaller bottom is larger, so the blade mold is overlapped on the upper sides of the two rotating telescopic plates for heating. At this time, only the lower sides of the blade mold are in contact with the upper sides of the rotating telescopic plates, and the lower side of the blade mold is suspended above the upper sides of the two rotating telescopic plates, which greatly increases the heating effect of the lower side of the blade mold; when the two rotating telescopic plates rotate upward respectively, so that the taper of the conical supporting interval with a larger top and a smaller bottom is smaller, and the two rotating telescopic plates are approximately parallel, at this time, the blade mold mainly has its lower side abutting against the upper sides of the two rotating telescopic plates. Since the blade mold generally has an arc-shaped structure, the lower sides of the blade mold do not contact the upper sides of the rotating telescopic plates, so that the lower sides of the blade mold can be quickly heated. In this way, heating is performed in two ways to achieve the purpose of rapid heating and drying.

[0017] 3. In order to avoid friction, the present invention arranges a wear-eliminating gasket on the upper side of the rotating telescopic plate. The wear-eliminating gasket is made of polytetrafluoroethylene material and has serrated ventilation grooves evenly distributed on the wear-eliminating gasket. In this way, hot air flow will enter the bottom of the blade mold from the serrated ventilation grooves evenly distributed on the wear-eliminating gasket, thereby greatly increasing the heat drying effect.

[0026] Furthermore, a sliding channel 341 is provided at the upper end of the rotating and telescopic plate 34; the rotating and telescopic plate 34 is slidably sleeved on the lower end of the rotating rod 33 through the sliding channel 341 at the upper end; abutment elastic bodies 343 are respectively provided in the sliding channels 341 at the upper end of the rotating and telescopic plate 34; the two ends of the abutment elastic bodies 343 are respectively elastically abutted between the rotating rod 33 and the inner end of the sliding channel 341.

[0027] Further, the telescopic driving mechanism 4 includes a driving motor 41, a rotating shaft 42, a rotating screw 43, a floating threaded cylinder 44, a connecting plate 45, a guide cylinder 47, and a guide rod 46; a floating threaded cylinder 44 is installed in the middle of the bottom of the connecting frame 37; an internal thread groove is provided inside the lower end of the floating threaded cylinder 44; the driving motor 41 is fixedly installed in the middle of the bottom lower end of the drying bin body 1; the upper end of the driving motor 41 is connected to the rotating shaft 42; the driving motor 41 drives the rotating shaft 42 to rotate in reverse; the upper end of the rotating shaft 42 is connected to the rotating screw 43; the upper end of the rotating screw 43 is threadedly connected to the lower end of the floating threaded cylinder 44; a connecting plate 45 is installed on both sides of the connecting frame 37; a guide rod 46 is vertically installed on the lower side of the connecting plate 45; a guide cylinder 47 is installed on both sides of the bottom lower end of the drying bin body 1; a guide groove 471 is provided inside the upper end of the guide cylinder 47; the lower ends of the guide rods 46 are respectively inserted into the guide grooves 471 connected to the guide cylinder 47.

[0028] Further, the lower end of the guide groove 471 of the guide cylinder 47 is connected with a threaded channel 472; the lower end of the threaded channel 472 is connected with a driving groove 473; the threaded channel 472 is internally threaded and rotatably connected with an abutting screw 48; the lower end of the abutting screw 48 extends into the driving groove 473, and the upper end of the abutting screw 48 extends into the guide groove 471.

[0029] The complete driving process of the present invention is as follows: the driving motor 41 drives the rotating shaft 42 to rotate, and the rotating shaft 42 drives the rotating screw 43 to rotate. Through the principle of thread engagement, the floating threaded cylinder 44 moves up and down on the rotating screw 43. When the floating threaded cylinder 44 moves upward, it drives the connecting frame 37 to move upward. When the connecting frame 37 moves upward, it drives the rotating clamping rods 35 on both sides of the upper end of the connecting frame 37 to rotate outward through the lower rotating shaft 36. At the same time, the rotating clamping rod 35 is slidably clamped in the sliding clamping groove 342 on the lower side of the rotating telescopic plate 34 through the sliding clamping block 351 at the upper end. The sliding clamping block 351 drives the rotating telescopic plate 34 and the rotating rod 33 to rotate upward around the upper rotating shaft 32, and the rotating telescopic plate 34 slides upward on the outside around the lower end of the rotating rod 33 through the sliding channel 341 at the upper end, thereby changing the taper of the conical support interval 6 with a larger upper part and a smaller lower part formed by the two rotating telescopic plates 34; the reverse operation principle is the same as above.

[0030] The present invention controls the downward rotation angles of the two rotating retractable plates 34 to change the size of the suspended lower space when the blade mold 5 overlaps the upper side of the two rotating retractable plates 34. The larger the lower space, the faster the airflow and the better the drying effect. This can be adjusted according to different drying requirements. Figure 2 and 3 As shown, the present invention realizes two forms of heating modes of the blade mold 5. When the two rotating telescopic plates 34 are rotated downward respectively, the tapering of the conical support interval 6 with a larger upper part and a smaller lower part formed in this way is larger, so that the blade mold 5 is overlapped on the upper sides of the two rotating telescopic plates 34 for heating. At this time, only the lower sides of the blade mold 5 are in contact with the upper side surfaces of the rotating telescopic plates 34, and the lower side surface of the blade mold 5 is suspended on the upper sides of the two rotating telescopic plates 34, which greatly increases the heating effect of the lower side surface of the blade mold; when the two rotating telescopic plates 34 are rotated upward respectively, so that the tapering of the conical support interval 6 with a larger upper part and a smaller lower part is smaller, and the two rotating telescopic plates 34 are approximately parallel, at this time, the blade mold is mainly in contact with the upper sides of the two rotating telescopic plates 34 by the lower side surface. Since the blade mold 5 is generally an arc-shaped structure, the lower sides of the blade mold do not contact the upper side surfaces of the rotating telescopic plates 34, so that the lower sides of the blade mold 5 can be quickly heated. In this way, heating is performed in two ways to achieve the purpose of rapid heating and drying. In order to avoid friction, the present invention sets a wear-reducing gasket 38 on the upper side of the rotating telescopic plate 34. The wear-reducing gasket 38 is made of polytetrafluoroethylene material, and serrated ventilation grooves 381 are evenly distributed on the wear-reducing gasket 38. In this way, the hot air flow will enter the bottom of the blade mold 5 from the serrated ventilation grooves 381 evenly distributed on the wear-reducing gasket 38, thereby greatly increasing the heat and drying effect below the blade mold 5.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
