Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude wind power generation, in particular to a horizontal stabilizing mechanism of a wind power generation device. Background Art

[0002] High-altitude wind power generation technology uses tethered cables to keep an aircraft suspended or moving along a defined trajectory. The technology converts the wind's kinetic energy into kinetic energy for the blades or winch, and then into electrical energy. Depending on the location of the generator, high-altitude wind power systems are categorized as land-based or air-based, each with two distinct implementation methods.

[0003] Since the strength of high-altitude winds fluctuates to a certain extent, the connection angle between the mooring rope and the main body will change accordingly, resulting in the balance point of the high-altitude wind turbine itself not being uniquely determined.

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figure 1 As shown, the present invention proposes a horizontal stabilization mechanism for a wind turbine generator system, comprising a wind turbine main body 1, comprising a generator set 101, which includes a lightweight paddle-type generator and an outer casing. A set of fixing rings 2 for securing dual mooring ropes 3 are sleeved onto the outer circumferential surfaces of both ends of the generator set 101. The two dual mooring ropes 3 form an angle with each other, and the forces acting on the two mooring ropes change with changes in wind speed, thereby preventing the formation of pitch angles. A cable runs parallel to the dual mooring ropes 3, which are used for power transmission. The dual mooring ropes are not two independent mooring ropes, but rather two parallel mooring ropes separated near the high-altitude wind turbine and tied to the front and rear ends of the lightweight paddle-type generator. The forces acting on the two mooring ropes change with changes in wind speed, thereby preventing the formation of pitch angles.

[0022] The formula for calculating the power generation of a wind turbine is:

[0023]

[0024] Where v is the wind speed, p is the air density, R is the radius of the generator blade, t is any time, η is the generator efficiency, and CP is the blade coefficient (the ratio of actual thrust to theoretical thrust, which ranges roughly from 0.4 to 0.7).

[0025] The air mass hitting the fan blades during time t:

[0026] m=pπR 2 vt

[0027] The energy obtained by the fan blades in time t:

[0028]

[0029] The power of the fan blades during time t:

[0030]

[0031] Wind turbine power generation:

[0032]

[0033] Through formula (2)(3) and Figure 1 Calculations show that the wind speed at 500m is approximately 96km / h (80 / 3m / s = 26.67m / s), the air density is 1.29kg / m³, and the turbine blade radius is 3m. Since the specific model of lightweight propeller generator and the exact wind farm location are unknown, the blade coefficient and turbine efficiency cannot be accurately determined. Here, CP is assumed to be a minimum value of 0.4, and η is taken as 0.8.

[0034] Wind turbine power generation:

[0035]

[0036] like Figure 1 and Figure 3 As shown, the two fixing rings 2 are fixedly connected to a first connecting plate 201 and a second connecting plate 203, and the two first connecting plates 201 are provided with a threaded groove, in which a first stud 202 is threadedly connected, and the two first connecting plates 201 are connected through the first stud 202, and the two second connecting plates 203 are provided with a threaded groove, in which a second stud 204 is threadedly connected, and the two second connecting plates 203 are connected through the second stud 204, and the two second connecting plates 203 are provided with a circular hole, in which a connecting ring 205 is movably fitted, and one end of the two connecting rings 205 is connected to one end of the double mooring rope 3, and the fixing ring 2 is fixed to the casing of the generator set 101 through the first stud 202 and the second stud 204, thereby being used to fix the double mooring rope 3.

[0037] An upper wind-resistant wing 102 is fixedly connected to the outer peripheral surface of the generator set 101. A set of side wind-resistant wings 103 are fixedly connected to the outer peripheral surface of the generator set 101. The angle between the upper wind-resistant wing 102 and the side wind-resistant wing 103 is 120 degrees.

[0038] The interior of the wind-resistant wing is hollow and is filled with a polyethylene packaging bag filled with helium. The polyethylene packaging bag is double-layered. The volume of a single wind-resistant wing is According to the buoyancy formula F=pvg, the three wind-resistant wings can provide a total buoyancy of 1.29×18×10232.2N.

[0039] A light blade 104 is installed at one end of the generator set 101. A cavity is opened at one end of the light blade 104 at the hemisphere, and an emergency safety landing system is installed in the cavity.

[0040] This system is designed to reduce the speed of the aircraft during a fall, minimizing damage to the ground and the generator itself, while also allowing sufficient time for ground personnel to be alerted and evacuated. The emergency safety landing system, located in a hemispherical device in front of the blade connection, consists of an accelerometer, parachute, siren, and BDS positioning. It's placed at the very front of the generator because the tail, a two-dimensional structure, is less susceptible to damage when landing first, compared to the blades. If the blades were positioned at the bottom, they would be more susceptible to breakage if tilted, increasing repair costs. If a helium leak in the aircraft's wind-resistant fins causes a fall, the accelerometer will detect a significant increase in vertical acceleration, deploying the parachute to reduce the aircraft's fall speed. The BDS positioning system will also transmit the aircraft's location to personnel, providing early warning of the potential fall. A siren will sound when the generator is within 15 meters of the ground, alerting any personnel in the area who may have not yet evacuated. After a smooth landing, personnel can recover the generator using the BDS positioning system.

[0041] A connecting column 105 is fixedly connected to the upper part of the generator set 101, and a steering tail 106 is fixedly installed on the connecting column 105. The function of the steering tail is mainly reflected in that when the wind direction changes, the direction of the wind turbine is adjusted in time to avoid the waste of wind energy caused by the angle between the blades and the wind direction. If the blades are not facing the direction of the wind, the wind will generate thrust on the vertical surface of the tail, making the force on the generator unstable, thus adjusting the direction. This passive steering method can achieve steering quickly without consuming energy, thereby maximizing power generation efficiency.

[0042] like Figure 2 As shown, three horizontal stabilizers 107 are fixedly installed on the outer peripheral surface of the generator set 101 between the upper wind-resistant wing 102, the side wind-resistant wing 103 and between the two side wind-resistant wings 103. The angle between the three horizontal stabilizers 107 is 120 degrees.

[0043] The triple-track horizontal stabilizer and the double-tethered ...

[0044] like Figure 1 and Figure 1As shown, the other end of the double mooring rope 3 is connected to a mechanical winch 4, which is mounted on a support plate 5. A servo motor 6 is mounted on the support plate 5. The output end of the servo motor 6 passes through the support plate 5 and is connected to the mechanical winch 4. The support plate 5 is fixedly mounted on a base plate 7. The rotation of the mechanical winch 4 is controlled by the servo motor 6, thereby controlling the length of the double mooring rope 3 and thus controlling the position height of the wind turbine generator 1.

[0045] In this embodiment, a fixing ring 2 is secured to the outer casing of the generator set 101 via a first stud 202 and a second stud 204, thereby securing a dual mooring rope 3. The two mooring ropes 3 are angled so that the forces acting on them change with wind speed, thereby preventing pitch angles. A cable runs parallel to the dual mooring ropes 3, which transmit power. The dual mooring ropes are not two independent mooring ropes, but rather two parallel mooring ropes that are separated near the high-altitude wind turbine and attached to the front and rear ends of the lightweight blade-type generator. The forces acting on the two mooring lines change with wind speed, thus preventing the occurrence of pitch angles. A lightweight blade 104 is mounted on one end of the generator set 101. A cavity is located at one end of the hemisphere, housing an emergency safety landing system. This system is designed to reduce the speed of a fall, minimizing damage to the ground and the generator itself, while also allowing sufficient time for ground personnel to provide early warning and evacuate. A connecting column 105 is fixedly attached to the upper portion of the generator set 101, on which a steering tail 106 is fixedly mounted. The steering tail 106 serves to promptly adjust the orientation of the wind turbine when wind direction changes, avoiding wasted wind energy caused by an angle between the blades and the wind direction. The three-track horizontal device functions similarly to the dual mooring lines, both of which maintain balance in the pitch direction of the high-altitude wind turbine. However, the principle behind the horizontal stabilizer differs from that of the dual mooring lines; it achieves balance by shifting the center of gravity of the high-altitude wind turbine.

[0046] Example 2

[0047] like Figure 1 and Figure 4As shown, based on the embodiment 1, a battery pack 8 is installed on the substrate 7, and a port 801 is installed on the battery pack 8. The port 801 is connected to the power output end of the generator set 101 through a cable, and can receive the wind energy converted by the generator set 101, thereby converting the wind energy into electrical energy storage. The battery pack 8 can be incorporated into the power grid for regional residential electricity use. At the same time, a limit plate 9 is installed on the substrate 7, and a fixing plate 10 is installed on the substrate 7. The fixing plate 10 has a rectangular groove, and a set of fixing blocks are fixedly connected to the substrate 7. 11. An electric push rod 12 is installed on the two fixed blocks 11, and a clamping block 13 is fixedly connected to the two electric push rods 12. An arc groove is opened on the two clamping blocks 13, and a connecting column 105 is clamped and fixed between the two clamping blocks 13. When the wind turbine main body 1 needs to be retracted due to special weather, the limit plate 9 and the fixing plate 10 are used to place and position the wind turbine main body 1, and then the electric push rod 12 is unfolded to fix the clamping block 13 on the connecting column 105 of the wind turbine main body 1, thereby fixing the wind turbine main body 1.
