Its core principle is to use wind power to drive the blades to rotate and drive the generator to generate electricity.

This patented design buries the entire wind turbine generator in the ground, concentrating external wind power through a wind collection duct to drive the blades and generator. Compared to traditional high-altitude installations, this underground design offers advantages such as convenient installation and maintenance, and lower costs.

[0037] Example 1

Each strip groove 72 is connected to a corresponding receiving hole 71; each receiving hole 71 is equipped with an air inlet pipe 8, and each air inlet pipe 8 has a mounting rod 81 fixedly connected to its upper and lower ends. The lower mounting rod 81 is fixedly connected to the outer air duct 7, and the upper mounting rod 81 is fixedly connected to the inner air duct 9. The upper mounting rod 81 slides in the strip groove 72, and the air inlet pipe 8 is made of a deformable material; the inner air duct 9 has several air inlet holes 91, and the air inlet holes 91 correspond to the receiving holes 71; a mounting plate 102 is fixedly connected inside the inner air duct 9; the mounting plate 102 is connected to a linkage unit.

[0040] The linkage unit includes a connecting rod 11, a first locking block 41, and a second locking block 1102; the rotating shaft 4 is hollow; the mounting plate 102 is fixedly connected to the connecting rod 11, which is located in the hollow part of the rotating shaft 4 and is slidably connected to the rotating shaft 4; several first locking blocks 41 are fixedly connected to the upper end of the rotating shaft 4; the connecting rod 11 is fixedly connected to the second locking blocks 1102, which are the same number as the first locking blocks 41, and the second locking blocks 1102 are staggered with the first locking blocks 41, and each second locking block 1102 can be inserted between two adjacent first locking blocks 41.

[0041] It also includes air guide vanes 101; four air guide vanes 101 are fixedly connected to the mounting plate 102, and each air guide vane 101 corresponds to an air inlet 91.

[0042] It also includes a steering unit, which includes a linkage collar 111, a worm gear 112, a rotating rod 113, a DD motor 114, and a worm 115; a wind direction sensor is installed at the top of the inner air duct 9; several flat keys 1101 are installed on the connecting rod 11; the connecting rod 11 is slidably connected to the linkage collar 111, the linkage collar 111 has several keyways corresponding to the flat keys 1101, and the linkage collar 111 is rotatably connected to the rotating shaft 4; the rotating rod 113 is rotatably connected inside the outer casing 2; the DD motor 114 is fixedly connected to the inner wall of the outer casing 2, and the rotating part of the DD motor 114 is fixedly connected to the rotating rod 113; the linkage collar 111 is fixedly connected to the worm gear 112; the rotating rod 113 is fixedly connected to the worm 115, and the worm 115 meshes with the worm gear 112.

[0043] It also includes an exhaust pipe 121; the upper part of the outer casing 1 has several vent holes 02, so that the interior of the outer casing 1 is connected to the interior of the outer casing 2; the outer casing 1 is connected to the exhaust pipe 121, and the exhaust pipe 121 is connected to the outside through an external pipe.

[0044] The upper end of the second card block 1102 is chamfered to facilitate the movement of the second card block 1102 into the space between the first card block 41.

[0045] The diameter of the end of the air inlet pipe 8 near the outer air duct 7 is smaller than the diameter of the end away from the outer air duct 7. When the outside wind enters the air inlet pipe 8, the wind speed entering the air inlet pipe 8 gradually increases through the gradually narrowing air inlet pipe 8, thereby increasing the rotation speed of the blades 5 and making the power generation efficiency higher.

[0046] Figure 2 In the normal operating state of the wind turbine, outside wind enters the inner duct 9 through the air inlet 8 and the air inlet 91. Guided by the air guide vanes 101, the wind flows downward in the inner duct 9 and enters the outer casing 2, causing the blades 5 and the rotating shaft 4 to rotate. The rotating shaft 4 drives the generator body 3 to generate electricity. In the normal operating state, the flat key 1101 on the connecting rod 11 engages with the keyway of the linkage collar 111. The wind direction sensor installed at the top of the inner duct 9 monitors the outside wind direction and controls the DD motor 114 to drive the rotating rod 113 and the worm gear 115 to rotate according to the wind direction change. The worm gear 115 drives the worm wheel 112 and the linkage collar 111 to rotate. The linkage collar 111 drives the connecting rod 11 and the connecting rod 111 connected to the flat key 1101. Rotating the rotating disk 6, the outer air intake pipe 7, the air inlet pipe 8, and the inner air intake pipe 9 adjusts the orientation of the air inlet pipe 8, ensuring it always faces the outside wind direction, thereby improving the efficiency of wind power generation. Simultaneously, the airflow entering the interior of the outer casing 2 enters the interior of the outer casing 1 through the vent 02, blowing on the generator body 3 inside the outer casing 1. This allows for heat dissipation of the generator body 3 during operation, and the cooled airflow is finally discharged to the outside through the exhaust pipe 121 and the external pipe. It should be noted that the diameter of the end of the air inlet pipe 8 near the outer air intake pipe 7 is smaller than the diameter of the end away from the outer air intake pipe 7. As the wind enters the air inlet pipe 8, the wind speed gradually increases through the gradually narrowing air inlet pipe 8, thereby increasing the speed at which the wind drives the blades 5 to rotate, resulting in higher power generation efficiency.

[0047] However, during rainy weather operation, rainwater enters the interior of outer casing 2 and outer casing 1 through the air inlet pipe 8, causing damage from immersion and affecting the stability and lifespan of the entire power generation system. To address this issue, when rainy weather is predicted, the electric push rod 10 is controlled in advance to move the inner air intake pipe 9 upwards. Since the mounting rod 81 at the lower end of the air intake pipe 8 is fixed to the outer air intake pipe 7, and the mounting rod 81 at the upper end is fixed to the inner air intake pipe 9, as the inner air intake pipe 9 continues to move upwards, it causes the mounting rod 81 at the upper end of the air intake pipe 8 to move upwards within the slot 72, thus pulling the air intake pipe 8 to gradually deform from a tubular shape to a flat shape. The movement stops when the inner air intake pipe 9 moves upwards to the point that the air inlet hole 91 is misaligned with the receiving hole 71 of the outer air intake pipe 7. Figure 10 As shown, the deformed air inlet pipe 8 and the outer air duct 7 together block the air inlet hole 91, thus preventing rainwater from entering the interior of the outer casing 2 and the outer casing 1 through the inner air duct 9 during rain and coming into contact with the internal electrical system. However, in rainy weather, outside wind cannot enter the outer casing 2, making it impossible to generate electricity in such weather. Therefore, as the inner air duct 9 moves upward, causing the air inlet pipe 8 to deform into a flat shape, the inner air duct 9 simultaneously moves the mounting plate 102 upward. The mounting plate 102 moves the connecting rod 11 upward, causing the flat key 1101 on the connecting rod 11 to disengage from the keyway of the linkage collar 111. The connecting rod 11 also moves the second locking block 1102 upward and inserts it between the two adjacent locking blocks 41 of the rotating shaft 4. Figure 11 As shown, at this time, the connecting rod 11 is engaged with the rotating shaft 4 by the first locking block 41 and the second locking block 1102. When it is rainy, the outside wind blows the flat air inlet pipe 8, which drives the outer air duct 7, the inner air duct 9 and the rotating disk 6 to rotate, which in turn drives the rotating shaft 4 and the blades 5 to rotate, so that the generator body 3 can work and generate electricity. By moving the inner air duct 9 upward, the air inlet pipe 8 is shaped into a flat shape, and the connecting rod 11 is engaged with the rotating shaft 4, so that even in rainy weather, the outside wind can still drive the generator body 3 to operate and generate electricity, thereby improving the overall power generation efficiency of the equipment.

[0048] After the rainy weather, the electric push rod 10 is controlled again to drive the inner air duct 9 to move downward and reset. The inner air duct 9 drives the mounting rod 81 at the upper end of the air inlet pipe 8 to move downward and reset, so that the air inlet pipe 8 is reshaped into a tube, the receiving hole 71 and the air inlet hole 91 are re-aligned and connected, and the connecting rod 11 moves downward and reset, disengaging from the rotating shaft 4, and returning to the normal working state to generate electricity.

[0049] Considering that in rainy weather, the air inlet duct 8 becomes flat and receives less wind force due to its proximity to the ground, the power generation efficiency of this method is lower than that of the method where wind directly enters the casing 2 through the air inlet duct 8 during normal operation. The difference in efficiency between the two power generation methods driving the generator body 3 results in instability in the voltage and frequency output of the generator body 3. This instability can easily interfere with or even damage the connected power grid and other electrical equipment. Therefore, this device is equipped with a frequency converter control system that adjusts the drive frequency under the two power generation methods in real time to keep the output of the generator body 3 within the preset power generation range. This avoids large fluctuations in the output power parameters when switching between different power generation methods, which could interfere with or even damage the connected power grid and other electrical equipment.

[0050] Example 2

[0051] Based on Example 1, referring to Figure 9 and Figures 12-15 As shown, it also includes an annular water collecting plate 201, a water pipe 202, a heat dissipation pipe 203, a lead screw 204, a bevel gear one 205, a bevel gear two 206, and an annular movable plate 207; the annular water collecting plate 201 is fixedly connected to the top of the outer shell 2; the outer shell 2 has a water storage cavity 03; six water pipes 202 are fixedly connected to the outer shell 2, each water pipe 202 is equipped with a one-way valve one 20201, and the water pipe 202 passes through the outer shell 2, with one end of the water pipe 202 connected to the outside and the other end connected to the water storage cavity 03; the outer shell 1 is fixedly connected to a heat dissipation pipe 203, the heat dissipation pipe 203 is attached to the surface of the generator body 3, and one end of the heat dissipation pipe 203 is connected to the water storage cavity 03, and the other end is connected to the outside through an external pipe; the annular movable plate 207 is slidably connected inside the water storage cavity 03 through a sliding rod; The annular movable plate 207 has several through holes 20701, and each through hole 20701 is equipped with a one-way valve 20702. Both the one-way valve 20201 and the one-way valve 20702 are set to open downwards. Two lead screws 204 are rotatably connected inside the water storage cavity 03. The upper end of the lead screw 204 is rotatably connected to the outer shell 2, and the lower end is rotatably connected to the outer shell 1. The middle part of the lead screw 204 is provided with a spiral groove, and the annular movable plate 207 cooperates with the spiral groove of the lead screw 204. The lead screw 204 drives the annular movable plate 207 to move up and down in the water storage cavity 03. Each lead screw 204 has a bevel gear 205 fixedly connected to its upper end. Each end of the rotating rod 113 has a bevel gear 206 fixedly connected to its two ends, and the bevel gear 205 meshes with the bevel gear 206.

[0052] The heat dissipation pipe 203 is designed in a spiral shape to increase the contact area with the generator body 3 and improve the heat dissipation effect.

[0053] It also includes an interception net 211; the outer air duct 7 is fixedly connected to the interception net 211, the interception net 211 covers the top of the annular water collection plate 201, and the interception net 211 is rotatably connected to the annular water collection plate 201.

[0054] The interception net 211 is designed as a cone shape with a high center and low edges. Debris falling on the interception net 211 can fall off to the sides as it rotates, preventing blockage of the interception net 211.

[0055] Based on the above embodiment 1, when the device is working in rainy weather, the wind cannot enter the interior of the outer casing 2 and the outer casing 1 to dissipate heat from the generator body 3. The generator body 3 will continuously generate heat during the power generation process, and the continuous accumulation of heat will damage the generator body 3.Therefore, an annular water collection plate 201 is also provided. During rainy weather, rainwater can be collected through the annular water collection plate 201. At the same time, during the rainwater collection, the flat key 1101 on the connecting rod 11 is disengaged from the keyway on the linkage collar 111. This controls the DD motor 114 to repeatedly drive the rotating rod 113 and the second bevel gear 206 to rotate forward and reverse. The second bevel gear 206 drives the first bevel gear 205 and the lead screw 204 to rotate forward and reverse, which in turn causes the lead screw 204 to drive the annular movable plate 207 to move up and down repeatedly in the water storage cavity 03. When the annular movable plate 207 moves downward in the water storage cavity 03, the space of the water storage cavity 03 located above the annular movable plate 207 expands, and the air pressure increases. The pressure decreases, and under the action of air pressure, the one-way valve 20201 inside the water pipe 202 is pushed downwards, allowing the rainwater collected at the annular water collecting plate 201 to enter the water pipe 202 and then into the water storage chamber 03 on the upper side of the annular movable plate 207. When the annular movable plate 207 moves down to the lowest point of the spiral groove of the screw 204, the DD motor 114 is controlled to reverse, driving the annular movable plate 207 to move upwards within the water storage chamber 03. The space of the water storage chamber 03 on the upper side of the annular movable plate 207 shrinks, and the pressure increases; the space of the water storage chamber 03 on the lower side of the annular movable plate 207 expands, and the pressure decreases. Under the action of air pressure, the rainwater entering the water storage chamber 03 on the upper side of the annular movable plate 207 pushes the annular movable plate 207 upwards. The one-way valve 20702 inside the through hole 20701 of the movable plate 207 is opened, allowing rainwater to enter the water storage chamber 03 on the lower side of the annular movable plate 207. When the annular movable plate 207 moves upward to the highest point of the spiral groove of the screw 204, the DD motor 114 is controlled to rotate forward again, driving the annular movable plate 207 to move downward in the water storage chamber 03. The downward movement of the annular movable plate 207 compresses the space of the water storage chamber 03 on the lower side of the annular movable plate 207, causing the space of the water storage chamber 03 on the upper side of the annular movable plate 207 to expand and the pressure to decrease. The rainwater collected at the annular water collecting plate 201 once again opens the one-way valve 20201 and enters the water storage chamber 03 on the upper side of the annular movable plate 207. The space of the water storage chamber 03 under the moving plate 207 decreases, and the pressure increases. Under the action of air pressure, the rainwater entering the water storage chamber 03 under the annular moving plate 207 is forced into the heat dissipation pipe 203, and the rainwater flows within the heat dissipation pipe 203. The heat dissipation pipe 203 is in contact with the surface of the generator body 3, thereby carrying away the heat generated by the generator body 3. The rainwater after heat exchange is finally discharged to the outside through an external pipe. In this way, by driving the annular moving plate 207 to move up and down repeatedly in the water storage chamber 03, the collected rainwater is forced into the heat dissipation pipe 203, and the flow of rainwater carries away the heat generated by the generator body 3, thus solving the problem of the generator body 3 being unable to dissipate heat when the equipment is working in rainy weather.

[0056] Meanwhile, considering that external debris may fall into the annular water collection plate 201 and cover and block the water pipe 202, preventing it from dissipating heat, an interception net 211 is installed. The interception net 211 can intercept external debris to prevent it from covering and blocking the water pipe 202, thus preventing subsequent heat dissipation. The interception net 211 is designed as a cone shape with a higher center and lower edges. At the same time, the interception net 211 is fixedly connected to the air intake pipe 7 and rotatably connected to the annular water collection plate 201. As the wind drives the air intake pipe 8 and the air intake pipe 7 to rotate, the air intake pipe 7 drives the interception net 211 to rotate, throwing out the debris that falls on the interception net 211, preventing the interception net 211 from being blocked and ensuring the collection of rainwater.

[0057] It should be understood that the above description is for illustrative purposes only and is not intended to limit the invention. Those skilled in the art will understand that variations of the invention are included within the scope of the claims herein.
