[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The utility model embodiment discloses a blade lock electric control cabinet for a wind turbine generator set.

[0022] The utility model provides Figure 1-3 The wind turbine blade lock electric control cabinet shown in the figure includes a blade shaft 1 and a cabinet body 2 rotatably sleeved with the blade shaft 1, two screw rods 3 are symmetrically rotatably arranged inside the cabinet body 2, the rod walls of the two screw rods 3 are threadedly sleeved with sliders 4, the side walls of the two sliders 4 are provided with connecting mechanisms and are respectively connected with plug rods 5 through corresponding connecting mechanisms, two slots are symmetrically provided on the surface of the blade shaft 1, and the two plug rods 5 are respectively movably inserted into the corresponding slots, a sleeve 6 movably sleeved with the blade shaft 1 is fixedly arranged on the inner wall of one side of the cabinet body 2, and a driving mechanism is arranged on the pipe wall of the sleeve 6, and the two screw rods 3 are both transmission-connected with the driving mechanism. By utilizing the cabinet body 2 rotatably sleeved with the blade shaft 1 and the structure arranged in the installation and the interior, the overall volume can be effectively shortened, and when the blade shaft 1 needs to be locked, it can be quickly locked by inserting the two plug rods 5 into the corresponding slots, thereby effectively ensuring the safety of the wind turbine.

[0023] like Figure 2-3 As shown, the connecting mechanism includes a first connecting plate 7, a telescopic rod 8 and a second connecting plate 9. The telescopic rod 8 is fixedly arranged between the first connecting plate 7 and the second connecting plate 9. The side wall of the first connecting plate 7 is fixedly connected with an L-shaped rod 10, and is fixedly connected to the corresponding slider 4 through the L-shaped rod 10. The second connecting plate 9 is fixedly connected to the end of the corresponding insertion rod 5. The rod wall of the telescopic rod 8 is movably sleeved with a spring 11, and the two ends of the spring 11 are respectively fixedly connected to the first connecting plate 7 and the second connecting plate 9. By utilizing the two telescopic rods 8 and the corresponding springs 11, it is possible to avoid blocking the continued rotation of the two screw rods 3 at the moment when the two insertion rods 5 contact the blade shaft 1. At the same time, when the two slots on the surface of the blade shaft 1 are rotated to the position of the corresponding insertion rod 5, the elastic force of the spring 11 can squeeze the corresponding second connecting plate 9, so that the two insertion rods 5 can be smoothly inserted into the corresponding slots.

[0024] like Figure 2-3As shown, the driving mechanism includes a worm wheel 12, a worm 13 and two mounting plates 14. The worm wheel 12 is rotatably sleeved with a tube wall of a sleeve 6.

The two second bevel gears 17 are respectively fixedly connected to the ends of the corresponding screw rods 3. The two mounting plates 14 are rotatably sleeved with the rod walls of the corresponding screw rods 3. By utilizing the meshing connection between the worm 13 and the worm wheel 12, the first bevel gear 16 can be driven to rotate through the worm wheel 12 and the two connecting rods 15 during the rotation of the worm 13, so that the corresponding second bevel gear 17 can drive the corresponding screw rod 3 to rotate, thereby achieving the effect of driving the two plug rods 5 to move.

[0025] like Figure 2-3 As shown, a limit rod 18 is movably provided inside each first connecting plate 7, and the opposite ends of the two limit rods 18 are fixedly connected to the inner wall of the cabinet 2. By utilizing the set limit rods 18, the first connecting plate 7 can be limited to avoid being driven to rotate during the rotation of the screw rod 3.

By utilizing the set motor, the worm 13 can be driven to rotate during the operation of the motor, thereby realizing automatic driving of the driving mechanism.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
