Description

Technical Field

[0001] The invention relates to the technical field of generators, in particular to a wind generator. Background Art

[0002] A wind turbine is a device that converts wind energy into electrical energy. It is the core component of a wind power generation system, converting the kinetic energy of wind into mechanical energy, and ultimately generating electrical energy through a generator. In the event of excessive wind, equipment maintenance, grid problems, or other shutdowns, a high-speed shaft brake is required to stop the wind turbine. High-speed shaft brakes usually use friction braking or electromagnetic braking principles.

[0003] The shaft of the wind turbine is connected with fan blades, and the fan blades drive the shaft of the wind turbine to rotate under the action of wind force, thereby generating electricity. Generally, a friction brake is provided at the shaft of the wind turbine to control the rotation speed of the generator shaft.

[0004] When the fan blades drive the shaft to rotate at high speed, the rotor part located inside the wind turbine and connected to the shaft is affected by the inertia force. After the shaft is braked by the friction brake, the rotor part becomes loose between the shaft and the inertia force, causing damage to the wind turbine. Summary of the invention

[0005] The present invention provides a wind turbine generator, which solves the problems raised by the above background technology.

[0006] The present invention provides the following technical solution: a wind turbine, comprising an outer shell, an outer wall on one side of the outer shell is fixedly equipped with a swivel seat 1, an outer wall on the other side of the outer shell is fixedly equipped with a protective shell, an inner wall of the outer shell is fixedly equipped with a stator, and a rotor is rotatably sleeved on the inner wall of the stator, an outer wall on one side of the outer shell close to the protective shell is fixedly equipped with a swivel seat 2, an outer wall on one end of the rotor close to the protective shell is fixedly equipped with a fan heat leaf, and the fan heat leaf is located between the protective shell and the swivel seat 2, and an outer wall on the side of the rotor away from the protective shell is fixedly equipped with a fan blade.

[0007] As a preferred technical solution of the present invention: the rotor includes a shaft and a magnet assembly;

[0008] The shaft body and the inner wall of the magnet assembly are rotatably sleeved, and a limiting component is arranged between the shaft body and the magnet assembly.

[0009] As a preferred technical solution of the present invention: the shaft body includes a limiting column, one end of the limiting column is fixedly assembled with a connecting rod 1, and the other end of the limiting column is fixedly assembled with a connecting rod 2.

[0010] As a preferred technical solution of the present invention: the limiting component includes a limiting plate 1 fixedly assembled with the outer walls of both sides of the connecting rod 1, the outer wall of the limiting plate 1 is provided with a buffer groove, and the ends of the limiting plate 1 are both provided with an extrusion groove;

[0011] The limiting component also includes a sliding groove opened at the top of the second connecting rod, the inner wall of the sliding groove is slidably sleeved with a limiting rod, a one-way valve is arranged at the bottom of the limiting rod, and a sealing ring is fixedly sleeved on the top of the inner wall of the sliding groove.

[0012] As a preferred technical solution of the present invention: the inner cavity of the limiting column is provided with a flow groove;

[0013] The sliding groove is connected with the extrusion groove through the circulation groove, the one-way valve is fixedly assembled with the bottom end of the sliding groove, and the limit rod is sealed by the sealing ring and the sliding groove;

[0014] The extrusion grooves located on both sides of the limiting column open in opposite directions.

[0015] As a preferred technical solution of the present invention: the magnet assembly includes a magnetic body, both ends of the magnetic body are fixedly equipped with protective plates, the inner wall of the magnetic body is fixedly equipped with a mounting ring, the inner wall of the mounting ring is provided with a liquid groove, and the inner wall of the liquid groove is symmetrically provided with two groups of limit plates.

[0016] As a preferred technical solution of the present invention: the limiting column is located on the inner wall of the liquid tank, both ends of the limiting column are sealed with the inner wall of the mounting ring, and the inner cavity formed between the liquid tank and the limiting column is filled with liquid.

[0017] The present invention has the following beneficial effects:

[0018] 1. The wind turbine generator drives the limiting plate 1 to rotate through the limiting column, and the liquid filled in the inner cavity formed between the liquid tank and the limiting column passes through the buffer groove provided on the outer wall of the limiting plate 1, so that when the limiting column drives the limiting plate 1 located on the inner wall of the liquid tank to rotate, the liquid flows through one end of the buffer groove to the other end of the buffer groove;

[0019] During this process, the liquid is squeezed by the limit plate 1 and flows from the buffer groove, so that the rotation pressure of the limit plate 1 is reduced, thereby solving the problem that when the fan blades drive the shaft to rotate at high speed, the rotor part located inside the wind turbine and connected to the shaft is affected by the inertia force. After the shaft is braked by the friction brake, the rotor part is affected by the inertia force and becomes loose between the shaft, causing damage to the wind turbine.

[0020] 2. The wind turbine generator squeezes the liquid through the limit plate 1, and part of the liquid flows through the extrusion groove to the flow groove, and flows to the one-way valve through the sliding groove. Through the one-way fluidity of the one-way valve, the liquid flows to between the one-way valve and the limit rod, so that the limit rod moves upward, and then the connecting rod 2 is clamped and fixed through the limit rod and the clamping seat.

[0044] In a preferred embodiment: the inner cavity of the limiting column 711 is provided with a flow slot 717;

[0045] The sliding groove 718 is connected to the extrusion groove 716 through the flow groove 717, the one-way valve 719 is fixedly assembled with the bottom end of the sliding groove 718, and the limit rod 7110 is sealed with the sliding groove 718 through the sealing ring 7112;

[0046] The extrusion grooves 716 located on both sides of the limiting column 711 open in opposite directions.

[0047] In the above structure, the shaft 71 is rotatably connected to the swivel seat 1 4 and the swivel seat 2 8 through the limiting column 711, the connecting rod 1 712 and the connecting rod 2 713, and the limiting is achieved between the shaft 71 and the magnet assembly 72 by the limiting plate 1 714 fixedly assembled on the outer walls of both sides of the connecting rod 1 712.

[0050] In the above structure, the limiting column 711 is located on the inner wall of the liquid groove 724, so that when the limiting column 711 rotates, the limiting column 711 drives the limiting plate 1 714 to rotate, and the liquid filled in the inner cavity formed between the liquid groove 724 and the limiting column 711 passes through the buffer groove 715 opened on the outer wall of the limiting plate 1 714, so that when the limiting column 711 drives the limiting plate 1 714 to rotate on the inner wall of the liquid groove 724, the liquid flows through one end of the buffer groove 715 to the other end of the buffer groove 715;

[0056] During this process, the liquid flows from the buffer groove 715 through the squeezing of the limiting plate 1 714, so that the rotation pressure of the limiting plate 1 714 is reduced. Finally, the limiting plate 1 714 and the limiting plate 2 725 overlap, so that the shaft 71 drives the magnet assembly 72 to directly contact, so as to achieve the limiting of the shaft 71 and the magnet assembly 72, so that the shaft 71 drives the magnet assembly 72 and the stator 6 to perform magnetic cutting to generate electricity;

Through the unidirectional fluidity of the one-way valve 719, the liquid flows to between the one-way valve 719 and the limit rod 7110, so that the limit rod 7110 moves upward, and then the connecting rod 2 713 is clamped and fixed through the limit rod 7110 and the clamping seat 1.
