[0002] A wind turbine is a device that converts wind energy into electrical energy. A wind turbine is mainly composed of blades, a hub, a nacelle, a tower, and other parts. When the wind blows through the blades, the blades rotate due to the thrust of the wind. The rotation of the blades drives the rotor of the generator to rotate through a series of mechanical transmission devices, cutting the magnetic flux lines in the magnetic field, thereby generating electrical energy. Wind turbines have many advantages. First, it is a renewable clean energy that does not produce greenhouse gas emissions and is environmentally friendly. Second, wind energy is widely present in nature and is abundant in resources.

This improves the poor utilization effect of wind energy by the wind blades in the related art.

[0004] When the above-mentioned device is in use, the device can better accept the thrust of the wind, and the wind blades improve the utilization effect of wind energy. However, during the use of the above-mentioned device, there is a lack of control over the rotation speed of the wind blades. If there is strong wind, the wind blade part of the device will rotate too fast. When the speed of the wind blade is too fast, the wind blade will not be able to withstand the centrifugal force and will be damaged. Summary of the invention

[0005] The object of the present invention is to provide a wind turbine to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a wind turbine, comprising a base, a push rod 1 is fixedly connected to the top of the base, a wind shield is fixedly connected to the top of the push rod 1, after the device controls the speed of the rotating assembly, the speed of the rotating assembly is still too high, which means that the wind speed outside is too high and the device cannot withstand the excessively high wind speed. At this time, the device will raise the wind shield and retract the arc plate to the inside of the wind shield, so that the rotating assembly cannot rotate, thereby protecting the device, and the inner wall of the wind shield is movably connected to the base, and further comprising:

[0007] The transmission mechanism includes a shell 1 for fixing the customer inside the base, the inner wall of the shell 1 is fixedly connected with a detection component, the top of the shell 1 is fixedly connected with a shell 2, the outer wall of the shell 2 is rotatably connected with a rotating component through a bearing, the outer wall of the shell 1 is fixedly connected with a connecting ring 1, the inner wall of the shell 2 is fixedly connected with a pressure device, the equipment lowers the height of the auxiliary component by lowering the detection component, at which time the detection component will be squeezed onto the pressure device, and the equipment will lift the windshield only when the pressure device is squeezed and the rotation speed of the rotating component is too fast, and the inner wall of the shell 2 is fixedly connected with a connecting ring 1, and the inner wall of the shell 2 is fixedly connected with a pressure device. An annular plate 1 is fixedly connected, an annular plate 2 is also fixedly connected to the inner wall of the outer shell 2, the inner wall of the annular plate 2 is rotatably connected to a hollow shaft through a bearing, a cylinder is fixedly connected to the top of the hollow shaft, a groove is provided on the top of the cylinder, a magnet 1 is fixedly connected to the outer wall of the cylinder, and an acceleration device is fixedly connected to the bottom of the hollow shaft. By setting the acceleration device, the rotation speed provided by the rotating component is accelerated and then transmitted to the power generation device, thereby improving the power generation efficiency of the equipment, wherein the interior of the acceleration device is hollow in design to facilitate the passage of the connecting column, and a transmission rod is fixedly connected to the output end at the bottom of the acceleration device.

[0008] According to the above technical solution, the rotating component includes a hollow column one, the inner wall of the hollow column one is rotatably connected to the outer shell two through a bearing, the top of the connecting ring one is rotatably connected to the hollow column one through a bearing, the outer wall of the hollow column one is fixedly connected to the connecting ring two, the outer wall of the connecting ring two is fixedly connected to a connecting plate, and the end of the connecting plate away from the connecting ring two is fixedly connected to an arc plate, the arc plate is moved by the external wind speed, and then the hollow column one is driven to rotate through the connecting plate and the annular plate two, thereby providing power for the rotation of the rotating component.

[0009] According to the above technical solution, the top of the hollow column one is fixedly connected to a hollow plate, the bottom of the hollow plate is fixedly connected to an annular plate three, the outer wall of the annular plate three is rotatably connected to the outer shell two through a bearing, the inner wall of the annular plate three is fixedly connected to a sliding ring, and the inner wall of the sliding ring is movably connected to an auxiliary component.

[0010] According to the above technical solution, the outer wall of the bottom of the annular plate three is fixedly connected with the connecting ring three, the bottom of the connecting ring three is fixedly connected with the hollow column two, the outer wall of the hollow column two is rotatably connected with the annular plate one through a bearing, and the inner wall of the hollow column two is fixedly connected with the magnet two. Through the attraction of opposite poles, as the hollow column two drives the magnet two to rotate, the magnet two drives the magnet one on the cylinder to rotate together through the magnetic force. If the transmission device or the power generation device is stuck, the rotating component will not stop suddenly, thereby avoiding damage to the equipment caused by excessive rotation inertia during stopping.

[0011] According to the above technical solution, the detection component includes a push rod 2, the outer wall of the push rod 2 is fixedly connected to the outer shell 1, the top of the push rod 2 is fixedly connected to a U-shaped plate, the top of the U-shaped plate is fixedly connected to a force ring, the outer wall of the force ring is fixedly connected to a speed detection device, and the outer wall of the U-shaped plate is fixedly connected to the speed detection device.

[0012] According to the above technical solution, the auxiliary component includes a sliding column 1, the outer wall of the sliding column 1 is movably connected to the hollow plate, the bottom of the sliding column 1 is fixedly connected to the sliding column 2, the outer wall of the sliding column 2 is sleeved with a spring, the top of the spring is fixedly connected to the sliding column 1, and the bottom of the spring is fixedly connected to the sliding ring. When the equipment detects that the rotation rate of the rotating component is too fast, the power transmission between the rotating component and the transmission mechanism is changed from an active connection to a rigid connection, and the rotating component is slowed down by the resistance of the power generation equipment itself in the equipment, so as to avoid the detection component rotating too fast and causing damage to the equipment.

[0013] According to the above technical solution, a friction column is fixedly connected to the bottom of the sliding column 2. When the auxiliary component descends, the friction plate will be embedded in the groove on the top of the cylinder, so that the cylinder and the hollow column 2 are connected as a whole through the friction plate and the sliding column 2. The bottom of the friction column is fixedly connected to a connecting column, which passes through the cylinder and extends to the top of the U-shaped plate.

[0014] According to the above technical solution, a circular plate is fixedly connected to the bottom of the connecting column, and a detection strip is fixedly connected to the outer wall of the circular plate, wherein the circular plate is arranged between the force ring and the U-shaped plate, and the detection direction of the speed detection device is aligned with the circular plate. As the rotating component rotates, the circular plate at the bottom will be driven to rotate together, and the rotating circular plate will drive the detection strip to rotate, and the speed detection device calculates the rotation rate of the rotating component by recording the intervals at which the detection strip appears.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] 1. The present invention sets an auxiliary component. When the device detects that the rotation speed of the rotating component is too fast, the power transmission between the rotating component and the transmission mechanism is changed from an active connection to a rigid connection. The speed of the rotating component is reduced by the resistance of the power generation device in the device, so as to avoid the detection component rotating too fast and causing damage to the equipment.

[0017] 2. The present invention sets a rotating assembly. Under normal conditions, the power transmission between the rotating assembly and the transmission mechanism is an active connection. Through the attraction between the magnets, the hollow column 2 drives the cylinder to rotate. If the transmission device or the power generation device is stuck, the rotating assembly will not stop suddenly, thus avoiding damage to the equipment caused by excessive rotation inertia during stopping.

[0018] 3. The present invention can accurately detect the rotation speed of the rotating component by setting a detection component, rather than detecting it through the rotation speed of the transmission mechanism. This can more accurately detect the rotation speed of the rotating component and avoid errors in the detection of the rotation speed by the device, which causes the device to be unable to effectively control the rotation speed of the rotating component and ensure stable operation of the device.

[0019] 4. The present invention sets a wind shield. After the equipment controls the rotation speed of the rotating assembly, if the rotation speed of the rotating assembly is still too high, it means that the external wind speed is too high and the equipment cannot withstand the excessively high wind speed. At this time, the equipment will raise the wind shield and retract the arc plate to the inside of the wind shield, so that the rotating assembly cannot rotate, thereby protecting the equipment.
