When the temperature in the shell rises, the controller controls the motor I to start, the driving shaft of the motor I drives the driving block to rotate, the driving block drives the rotating plate to rotate around the horizontal axis of the driving block, the rotating plate rotates to one side far away from the shell, the axis of the rotating plate is vertical to the axis of the shell, the air conveying opening is communicated with the inside of the shell, and the air conveying opening is vertical to the air direction when the fan blade group rotates, so that the axis of the shell is parallel to the air direction, and when the air flows through the surface of the shell, the air is conveyed into the air conveying opening, and then the air is conveyed into the shell through the air conveying opening;
then wind moves along the axis of the shell, and in the process of flowing in the shell, the wind takes away the heat generated by the gear box and the generator, the wind is conveyed to the first air conveying pipe through the inner branch pipe and finally is discharged to the outside through the first air conveying pipe, so that the heat dissipation effect is achieved;

Because the main shaft is provided with the magnetic blocks, the arrangement mode of the magnetic blocks is as follows: the N pole of the magnetic block faces to one side of the edge of the main shaft, the S pole of the magnetic block faces to one side of the axis of the main shaft, and a magnet is arranged in the rotating plate, and the arrangement mode of the magnet is as follows: the N pole of the magnet is positioned at one side of the rotating plate close to the driving block, and the S pole of the magnet is positioned at one side of the rotating plate far away from the driving block;
When the rotating plate is positioned in the adjusting groove, the magnetic induction line direction of the magnet is perpendicular to the magnetic induction line direction of the magnetic block, so that the rotating plate can not adjust the rotation of the main shaft; when the axis of the rotating plate is in a vertical state with the axis of the shell, the magnetic induction line direction of the magnet is parallel to the magnetic induction line direction of the magnetic block, and the rotating plate can regulate the rotation of the main shaft;
When the rotating speed of the main shaft is too high, the controller controls the micro motor in the driving block to start, the driving shaft of the micro motor drives the rotating plate to rotate around the vertical axis of the rotating plate, so that the rotating plate deflects, the windward side of the rotating plate is opposite to the windward side of the fan blade group, then the rotating plate rotates under the action of wind force, the rotating plate rotates around the axis of the adjusting ring, and the rotating plate drives the adjusting ring to rotate when rotating, at the moment, the rotating direction of the adjusting ring is opposite to the rotating direction of the fan blade group, and the rotating speed of the adjusting ring is higher than the rotating speed of the fan blade group (namely the rotating speed of the main shaft) under the influence of the same wind force due to the fact that the rotating speed of the adjusting ring is lighter, and then the adjusting ring drives the magnet to rotate in the rotating process, so that N stages on the magnet continuously exceed N stages on the magnet, and then N stages on the magnet can repel N stages on the magnet; when the radial line of the magnet is in coincidence with the radial line of the magnet, the repulsive force between the magnet and the magnet is maximum, and when the magnet moves between two adjacent magnets, the acting force of the magnet on the two adjacent magnets tends to balance, and the acting force of the magnet and the magnet tends to balance because the rotating speed of the adjusting ring is larger than the rotating speed of the main shaft, and the acting force of the magnet and the magnet is longer than the acting force of the magnet and the magnet, and because the number of the magnets is larger than the number of the magnet, the acting force of the magnet on the magnet is always generated in the rotating process of the magnet;
The magnet generates a rotation repulsive force to the magnetic block, so that the magnet in the rotating plate generates resistance to the magnetic block in the main shaft, and the main shaft is prevented from rotating under the influence of magnetic force, so that the rotating speed of the main shaft is reduced, and the loss of a gear box and a generator caused by too high rotating speed is avoided;
When the rotating speed of the main shaft is too slow, the rotating plate deflects to the opposite direction, so that the windward side of the rotating plate is the same as the windward side of the fan blade group, the rotating direction of the adjusting ring is the same as the rotating direction of the fan blade group, the adjusting ring drives the magnet to rotate in the rotating process, N stages on the magnet continuously cross N stages on the magnet, the N stages on the magnet can be repelled by the N stages of the magnet, and the rotating speed of the magnet is larger than the rotating speed of the magnet, so that the magnet can generate rotating repulsive force for the magnet, but the rotating direction of the adjusting ring is the same as the rotating direction of the fan blade group, the magnet can generate auxiliary effect for the magnet, so that the magnet in the rotating plate generates auxiliary force for the magnet in the main shaft, the main shaft is smooth under the influence of the magnetic force, the rotating speed of the main shaft is increased in an auxiliary mode, the too slow rotating speed is avoided, and the generating efficiency is not high.
Compared with the prior art, the invention has the following beneficial effects:
1. The main shaft drives the rotating column to rotate, so that the rotating column generates centrifugal forces of different sizes, and the gravity ball moves under the counter action of the centrifugal force and gravity, so that the rotation speed of the main shaft is detected, and the working stability of the wind generating set is improved.
2. When the rotating plate is positioned in the adjusting groove, the magnetic induction line direction of the magnet is perpendicular to the magnetic induction line direction of the magnetic block, so that the rotating plate can not adjust the rotation of the main shaft; when the axis of the rotating plate is in a vertical state with the axis of the shell, the magnetic induction line direction of the magnet is parallel to the magnetic induction line direction of the magnetic block, and the rotating plate can regulate the rotation of the main shaft.

then wind moves along the axis of the shell 1, and in the process of flowing in the shell 1, the wind takes away the heat generated by the gearbox and the generator, the wind is conveyed to the first air pipe 35 through the inner branch pipe 351 and finally is discharged to the outside through the first air pipe 35, so that the heat dissipation effect is achieved;
In the process of radiating the inside of the shell 1 by wind, the controller controls the water pump in the water storage cavity to start, the water pump conveys water to the spraying port on the rotating plate 34 through the pipeline, and then the water is atomized and sprayed outwards through the spraying port, and as the water forms fog drops, the water is easier to evaporate, and the evaporative endothermic reaction is carried out, so that the temperature of the surrounding environment of the wind generating set is reduced;
While water is atomized and sprayed out, a part of atomized water flows along the outer surface of the shell 1, dust on the surface of the shell 1 is washed away by the water in the flowing process, so that the cleanliness of the outer surface of the shell 1 is improved, a part of air flowing in the shell 1 is conveyed to the outer branch pipe 361 through the second air conveying pipe 36, then the air is output to the outside through the outer branch pipe 361 and flows along the surface of the shell 1, and water stains remained on the surface of the shell 1 are blown off, so that the surface of the shell 1 is dried;
Because the main shaft 12 is provided with the magnetic blocks, the arrangement mode of the magnetic blocks is as follows: the N pole of the magnet faces to one side of the edge of the main shaft 12, the S pole of the magnet faces to one side of the axis of the main shaft 12, and a magnet is arranged in the rotating plate 34, and the arrangement mode of the magnet is as follows: the N pole of the magnet is positioned at one side of the rotating plate 34 close to the driving block, and the S pole of the magnet is positioned at one side of the rotating plate 34 far away from the driving block;
When the rotating plate 34 is positioned in the adjusting groove 31, the magnetic induction line direction of the magnet is vertical to the magnetic induction line direction of the magnetic block, so that the rotating plate 34 can not adjust the rotation of the main shaft 12; when the axis of the rotating plate 34 is in a vertical state with the axis of the housing 1, the magnetic induction line direction of the magnet is parallel to the magnetic induction line direction of the magnet, and the rotating plate 34 can regulate the rotation of the spindle 12;
When the rotating speed of the main shaft 12 is too high, the controller controls the micro motor in the driving block to start, the driving shaft of the micro motor drives the rotating plate 34 to rotate around the vertical axis of the rotating plate 34, so that the rotating plate 34 deflects, the windward side of the rotating plate 34 is opposite to the windward side of the fan blade group 11, then the rotating plate 34 rotates under the action of wind force, the rotating plate 34 rotates around the axis of the adjusting ring 32, the adjusting ring 32 is driven to rotate when the rotating plate 34 rotates, at the moment, the rotating direction of the adjusting ring 32 is opposite to the rotating direction of the fan blade group 11, and the rotating speed of the adjusting ring 32 is larger than the rotating speed of the fan blade group 11 (namely the rotating speed of the main shaft 12) under the influence of the same wind force due to the light weight of the adjusting ring 32, so that the adjusting ring 32 drives the magnet to rotate in the rotating process, N stages on the magnet continuously exceed N stages on the magnet, and N stages on the magnet can repel N stages on the magnet; in the rotating process of the magnet, when the radial line of the magnet is coincident with the radial line of the magnet, the repulsive force between the magnet and the magnet is the largest, and when the magnet moves between two adjacent magnets, the acting force of the magnet on the two adjacent magnets tends to be balanced, and the rotating speed of the adjusting ring 32 is higher than the rotating speed of the main shaft 12, so that the acting force of the magnet and the magnet is longer than the acting force of the magnet and the magnet tends to be balanced, and the number of the magnets is higher than the number of the magnet, so that the magnet always has the acting force on the magnet in the rotating process;
The magnets generate rotation repulsive force to the magnetic blocks, so that the magnets in the rotating plate 34 generate resistance to the magnetic blocks in the main shaft 12, and the main shaft 12 is prevented from rotating under the influence of magnetic force, so that the rotating speed of the main shaft 12 is reduced, and the loss of a gear box and a generator caused by too high rotating speed is avoided;
When the rotation speed of the main shaft 12 is too slow, the rotating plate 34 deflects in the opposite direction, so that the windward side of the rotating plate 34 is the same as the windward side of the fan blade set 11, the rotation direction of the adjusting ring 32 is the same as the rotation direction of the fan blade set 11, the adjusting ring 32 drives the magnet to rotate in the rotating process, the N level on the magnet continuously passes over the N level on the magnet, the N level on the magnet can repel the N level on the magnet, and the rotation speed of the magnet is larger than the rotation speed of the magnet, so that the magnet can generate a rotation repulsive force on the magnet, but at the moment, the rotation direction of the adjusting ring 32 is the same as the rotation direction of the fan blade set 11, so that the magnet can generate an auxiliary force on the magnet, so that the main shaft 12 slides smoothly under the influence of magnetic force, the rotation speed of the main shaft 12 is increased in an auxiliary manner, the over-slow rotation speed is avoided, and the power generation efficiency is not high.
