At the same time, the first guide plate 4 and the second guide plate 3 are provided in the present application, thereby forming a flow channel for the airflow in the blade 1, so that the heated airflow can flow in a predetermined direction, thereby completing the heating of the entire interior of the blade 1. The leaf-shaped guide block 5 provided at one end of the first guide plate 4 allows the airflow to flow to the tip of the blade 1, thereby avoiding the freezing of the blade 1 due to the blade 1 being too far away from the heating position, thereby completing the de-icing of the blade 1.

The temperature of the blade tip is increased by 2%. The heated air flow is then directed along the air outlet pipe 23 through the provided blower assembly 21, so that the air flow overflows the air outlet pipe 23 from the air outlet holes on the circumference of the air outlet pipe 23, and then flows along the gas flow channel separated by the provided first guide plate 4 and second guide plate 3 in the blade 1, thereby increasing the temperature of the cavity. In order to improve the heating efficiency of the blade tip, the regulating cylinder 25 starts to work, and the moving regulating cylinder 25 can drive the baffle 24 to move so that the sleeve 26 can move on the air outlet pipe 23. The sleeve 26 can cover the air outlet holes on the air outlet pipe 23, and the gas is discharged from one end of the air outlet pipe 23. By reducing the overflow area of the gas, the gas can quickly reach the tip of the blade 1, thereby completing the de-icing work on the tip of the blade 1.

[0057] The blower assembly 21 includes a guide tube 216 arranged in the blade 1, a mounting seat 212 arranged on the guide tube 216, a snap-on cover 213 snapped with the mounting seat 212, and a motor fan 214 built into the snap-on cover 213; the mounting seat 212 is provided with a plurality of limiting protrusions 215, and limiting grooves adapted to the limiting protrusions 215 and located on the snap-on cover 213; the snap-on cover 213 is provided with a plurality of air inlet holes; the guide tube 216 includes a second arched channel 2162, a first arched channel 2161 connected to one end of the second arched channel 2162, a third arched channel 2163 connected to the other end of the second arched channel 2162, and a plurality of air inlet holes; and a fourth arched channel 2164 connected to the other end of the third arched channel 2163; the first arched channel 2161 extends a predetermined length toward the area between the second arched channel 2162 and the third arched channel 2163, and then bends toward the second arched channel 2162 to form a spiral protrusion 2165; a gap is formed between the first arched channel 2161 and the fourth arched channel 2164, and the gap between the two gradually decreases along the flow direction of the airflow; the airflow generated by the motor fan 214 flows along the second arched channel 2162, the third arched channel 2163, and the fourth arched channel 2164, and finally accelerates the airflow out of the gap between the first arched channel 2161 and the fourth arched channel 2164;

[0058] When the blower assembly 21 needs to start working, the motor fan 214 starts working. The moving motor fan 214 can make the air flow. Since the rotary protrusion 2165 and the first bow channel 2161 bend toward the second bow channel 2162, when the motor fan 214 is working, the air flow moves along the second bow channel 2162, the third bow channel 2163 and the fourth bow channel 2164, and then is discharged from the gap between the first bow channel 2161 and the fourth bow channel 2164. Since the gap gradually decreases along the direction of the air flow, the air flow speed is relatively large when the air flow is discharged from the guide tube 211, which can drive the external air flow to move and increase the air flow volume. Then the air flow enters the heater 22, and the heater 22 heats and allows the heated gas to pass through the outlet pipe 23.

[0061] The speed measuring unit 9 includes a support base 92 fixedly connected to the housing 10, a lifting motor 93 fixedly arranged on the support base 92, a driving gear 94 connected to the output end of the lifting motor 93, a driven gear 95 meshing with the driving gear 94, a rotating disk 96 connected to the driven gear 95, two guide wheels 97 arranged on the rotating disk 96, a driving rod 98 connected to the guide wheels 97, a lifting block 99 connected to the driving rod 98, and a speed meter 91 arranged on the lifting block 99; the support base 92 is also provided with a lifting rail 911 and a lifting slider 910 slidably connected to the lifting rail 911, and the lifting slider 910 is connected to the lifting block 99; the rotating disk 96 is provided with two semicircular waist-shaped holes, wherein the two waist-shaped holes have both The guide wheel 97 is located in the waist-shaped hole in a certain overlapping area; when speed measurement is required, the lifting motor 93 starts to work, and the moving lifting motor 93 can drive the active gear 94 to rotate, and the moving active gear 94 drives the driven gear 95 to rotate, thereby driving the rotating disk 96 to rotate, and the moving rotating disk 96 can make the guide wheel 97 move in the semicircular waist-shaped hole, so that the movement direction of the driving rod 98 is opposite, so that the two speedometers 91 can intermittently complete the speed measurement work, and then one of them can be used as a spare speedometer 91. When one of them is damaged, the speed measuring unit 9 can still perform the speed measurement work, and through the setting of the lifting motor 93, the height of the speedometer 91 can be adjusted, so that the speedometer 91 can be retracted into the housing 10 in harsh environments to avoid damage to the speedometer 91.

[0062] The adjusting assembly 8 includes an adjusting seat 82 fixedly mounted on the rotating seat 74, an adjusting motor 81 movably connected to the adjusting seat 82, a transmission screw 84 provided at the output end of the adjusting motor 81, a driving block 83 sleeved on the transmission screw 84, a driving frame 89 provided on the driving block 83 and movably connected to the adjusting seat 82, two first connecting rods 85 and two second connecting rods 87 movably connected to the driving frame 89, a limit frame 86 for connecting the other end of the first connecting rod 85 and sleeved on the main shaft 11, and an adjusting portion 88 for connecting the other end of the second connecting rod 87 and sleeved on the main shaft 11; the adjusting portion 88 includes The invention comprises a driven ring 882 sleeved on the main shaft 11, a plurality of movable rods 884 evenly arranged on the driven ring 882, a plurality of adapters 886 arranged on the base 14 and rotatably connected to the base 14, and an adjustment ring 885 arranged at one end of the adapter 886; one end of the movable rod 884 is movably connected to the adjustment ring 885; the adapter 886 is connected to the blade 1 through a flange; the other end of the second connecting rod 87 is movably connected to the driven ring 882, wherein the limit frame 86 is an annular structure, the inner wall of which is provided with a buffer pad, a preset distance between the buffer pad and the outer wall of the main shaft 11, and the main shaft 11 is radially limited by the provided limit ring;

[0063] In order to prevent the main shaft 11 from rotating too fast when the wind speed is high or low, causing the main shaft 11 to be in a loaded state or the blade 1 to rotate slowly, it is necessary to adjust the angle between the blade 1 and the main shaft 11, change the angle between the blade 1 and the airflow, and adjust the rotation rate of the blade 1. At this time, the adjusting motor 81 starts to work, and the moving adjusting motor 81 drives the transmission screw 84 to start working, thereby adjusting the position of the driving block 83 on the transmission screw 84. The moving driving block 83 can drive the driving frame 89 to move, thereby causing the driving frame 89 and the adjusting seat 82 to rotate relative to each other, and then the driving frame 89 and the adjusting seat 82 are moved. The moving driving frame 89 can drive the second connecting rod 87 to start working, thereby driving the driven ring 882 to move in the axial direction of the main shaft 11. The moving driven ring 882 can drive the movable rod 884 to move. The moving movable rod 884 can drive the adjusting ring 885 to rotate. The moving adjusting ring 885 can then drive the adapter 886 to rotate. Since the adapter 886 is connected to the blade 1 through a flange, it can drive the blade 1 to rotate, thereby adjusting the angle between the blade 1 and the airflow direction, changing the rotation speed of the blade 1, and preventing the blade 1 from rotating too fast or too slow.

[0064] Two supports are provided on the rotating seat 74, the main shaft 11 is set on the supports, and the driven ring 882 is located between one of the supports and the base 14. The driven ring 882 is moved within the area by adjusting the motor 81 to control the rotation angle of the blade 1 to avoid the blade 1 rotating at an excessive angle, which may cause damage to the entire power generation equipment.

[0065] The adjusting portion 88 also includes a first hinged rod 881 and a second hinged rod 883; the first hinged rod 881 is movably connected to the rotating seat 74 and the driven ring 882 respectively, and the second hinged rod 883 is movably connected to the driven ring 882 and the base 14 respectively; the first hinged rod 881 and the second hinged rod 883 have the same structure, and are both two support rods hinged to each other; by cooperating between the first hinged rod 881 and the second hinged rod 883, the position of the driven ring 882 on the main shaft 11 can be adjusted, which not only supports the driven ring 882, but also adjusts the rotation angle of the blade 1 by changing the hinge angle between the two support rods of the first hinged rod 881 and the second hinged rod 883, thereby ensuring the smooth operation of the power generation equipment. In a further embodiment, the heater 22 and adapter 886 are existing technologies, the heater 22 can increase the temperature in the cavity, the adapter 886 is a tubular structure, the adjustment ring 885 is sleeved on one end of the adapter 886, and the other end of the adapter 886 is connected to the blade 1 through a flange.

[0066] Explanation of the working principle: When it is necessary to increase the temperature of the cavity in the blade 1, the heater 22 starts working, thereby increasing the temperature of the area where the heater 22 is located, and then the heated air flow is made to flow along the outlet pipe 23 through the provided blower assembly 21, so that the air flow overflows the outlet pipe 23 from the outlet holes on the circumference of the outlet pipe 23, and then the air flow flows along the gas flow channel separated by the provided first guide plate 4 and second guide plate 3 in the blade 1, thereby increasing the temperature of the cavity. Then, in order to improve the heating efficiency of the blade tip, the regulating cylinder 25 starts working, and the moving regulating cylinder 25 can drive the baffle 24 to move so that the sleeve 26 can move on the outlet pipe 23. The sleeve 26 can cover the outlet holes on the outlet pipe 23, and the gas is discharged from one end of the outlet pipe 23. By reducing the overflow area of the gas, the gas can be quickly discharged. When the air blower assembly 21 is required to start working, the motor fan 214 starts working, and the moving motor fan 214 can make the air flow. Since the swirling protrusion 2165 and the first arched channel 2161 are bent toward the second arched channel 2162, when the motor fan 214 is working, the air flow moves along the second arched channel 2162, the third arched channel 2163 and the fourth arched channel 2164, and then is discharged from the gap between the first arched channel 2161 and the fourth arched channel 2164. Since the gap gradually decreases along the direction of the air flow, the air flow has a large air flow speed when it is discharged from the guide pipe 211, thereby being able to drive the external air flow to move, thereby increasing the air flow volume. Then, the air flow enters the heater 22, and the heater 22 heats the gas and allows the heated gas to pass through the outlet pipe 23.

[0067] The tower 6 is installed at a predetermined position to complete the installation of the power generation equipment. The blade 1 is driven by wind power, and then the blade 1 drives the base 14 to move, and then the moving base 14 can drive the main shaft 11 to rotate, and then the moving main shaft 11 can move the gear box 12 to drive the generator 13 to move, completing the work of wind power generation; when the direction of the blade 1 needs to be adjusted, the rotating motor 73 starts to work, and the moving rotating motor 73 can drive the driving gear 72 to rotate, so that the driving gear 72 and the ring gear 71 are relatively displaced, so that the rotating base 74 The position of the main shaft 11 and the blade 1 on the rotating seat 74 is adjusted to complete the adjustment of the position of the blade 1; when the speed measurement is required, the lifting motor 93 starts to work, and the moving lifting motor 93 can drive the driving gear 94 to rotate, and the moving driving gear 94 drives the driven gear 95 to rotate, thereby driving the rotating disk 96 to rotate, and the moving rotating disk 96 can make the guide wheel 97 move in the semicircular waist hole, so that the movement direction of the driving rod 98 is opposite, so that the two speed meters 91 can intermittently complete the speed measurement work, and then one of them can be used as a spare speed meter 9 1. When one of them is damaged, the speed measuring unit 9 can still perform the speed measuring work, and the height of the speed meter 91 can be adjusted by the provided lifting motor 93, so that the speed meter 91 can be retracted into the housing 10 in a harsh environment to avoid damage to the speed meter 91; when the rotation rate of the blade 1 needs to be adjusted, the adjusting motor 81 starts to work, and the moving adjusting motor 81 drives the transmission screw 84 to start working, thereby adjusting the position of the driving block 83 on the transmission screw 84, and the moving driving block 83 can drive the driving frame 89 to move, so that the driving frame 89 and the adjusting seat 82 rotate relative to each other. Then the moving driving frame 89 can drive the second connecting rod 87 to start working, thereby driving the driven ring 882 to move in the axial direction of the main shaft 11, and the moving driven ring 882 can drive the movable rod 884 to move, and the moving movable rod 884 can drive the adjusting ring 885 to rotate, and then the moving adjusting ring 885 can drive the adapter 886 to rotate. Since the adapter 886 is connected to the blade 1 through a flange, it can drive the blade 1 to rotate, thereby adjusting the angle between the blade 1 and the airflow direction, changing the rotation speed of the blade 1, and avoiding the blade 1 rotating too fast or too slow.
