Embodiment 1

[0048] An offshore wind turbine that retracts the blades according to the strength of the wind, such as Figure 1-10As shown, it includes a base plate 1, a support frame 2, a cylinder limit ring 3, a support plate 4, a rotating shaft 5, a generator 6, a movable transmission part 7, a push-off part 8, a support block 9, and a blade 10 And the torsion spring 11, the support frame 2 is fixedly connected to the base plate 1, the upper part of the support frame 2 adopts a ring structure, and the cylinder limit ring 3 is fixedly installed on the support frame 2, and the cylinder limit ring 3 is cylindrical , the support frame 2 is connected with a support plate 4 by bolts, the base plate 1 and the support plate 4 are connected with a rotating shaft 5 in a common rotation type, and the bottom end of the rotating shaft 5 is connected with a generator 6, and the generator 6 and the support plate 4 Fixedly connected, the base plate 1 is provided with a movable transmission part 7, the m...

Embodiment 2

[0053] On the basis of Example 1, such as Figure 11-14 As shown, it also includes an adjustment part 12, which is used to make the movable transmission part 7 retract the blade 10 according to the wind strength. The adjustment part 12 is arranged on the top of the support plate 4. , cylinder 123, piston plate 124, return spring 125, connecting frame 126, guide plate 127 and L-shaped push plate 128, support plate 4 tops are fixedly connected with column 121, and column 121 is cylindrical, and column 121 rotates with rotating shaft 5 Inflatable compression cushion 122 is fixedly installed on the outside of the column 121, and a cylinder 123 is fixedly connected to the top of the support plate 4. The interior of the cylinder 123 is a hollow structure, and the cylinder 123 communicates with the inflatable compression cushion 122. Plate 124, piston plate 124 is rectangular, is connected with the return spring 125 that is used to drive piston plate 124 to reset between piston plate...

Embodiment 3

[0058] On the basis of Example 2, such as Figure 15 As shown, a warning part 14 is also included, and the warning part 14 for reminding the staff to maintain the equipment is arranged on the top of the base plate 1. The warning part 14 includes a fixed plate 141, an alarm bell 142 and a switch 143, basically The top of the seat plate 1 is connected with a fixed plate 141 by bolts, the fixed plate 141 is symmetrically connected with an alarm bell 142 , and the top of the base plate 1 is provided with a switch 143 for controlling the operation of the alarm bell 142 .

[0059] When the support bar 85 moves due to the increased wind force, the support bar 85 will press the switch 143 and make the alarm bell 142 operate, thereby the effect of warning can be played to the staff. When the support bar 85 resets, it will no longer press the switch 143, The alarm bell 142 then stops operating, which is convenient for the staff to carry out maintenance work on the equipment.

Abstract

The invention relates to a generator, in particular to an offshore wind driven generator capable of retracting blades according to wind strength. The offshore wind driven generator comprises a base plate, a support frame, a cylinder limiting ring, a support plate and the like, the support frame is fixedly connected to the base plate, the cylinder limiting ring is fixedly installed on the support frame, and a support plate is connected to the support frame through a bolt. When the wind power is strong, blades can be folded to prevent the equipment from being damaged due to the action of strong wind, so that the service life of the equipment is prolonged, and when the wind power returns to normal state, the blades can be unfolded and normally operate to enable the generator to continuously generate power, so that the effect of timely folding and unfolding the blades is achieved.

Description

technical field [0001] The invention relates to a generator, in particular to an offshore wind power generator capable of retracting blades according to wind strength. Background technique [0002] In recent years, generators have become an inseparable tool in our lives. Generators can convert other forms of energy into electrical energy. Among them, offshore wind turbines use offshore wind power to generate electricity. Limited by land use, offshore wind turbines have gradually become a new field of wind power development. [0003] There are abundant wind resources at sea, but the strength of the wind is unstable. Sometimes the wind is strong, and sometimes the wind is small. Offshore wind turbines rotate through the blades in contact with the wind, and then the generators generate electricity. The existing offshore wind turbines are If strong winds are encountered during operation, the strong winds will easily damage the blades, cause damage to the equipment, and reduce i...
