Technical Field

[0001] This invention relates to the field of power generation equipment, and in particular to a wind power tower. Background Technology

[0002] my country possesses abundant wind energy resources; according to incomplete statistics, the country has 2.53 billion megawatts of usable wind energy. With the continuous maturation of wind power generation technology and the constant reduction in power generation costs, wind power has become one of the most important sources of electricity consumption for humankind. Wind power generation primarily relies on wind turbine generators operating under the influence of wind to produce electricity. However, currently, the assembly of wind turbine towers often presents installation difficulties and safety hazards due to the generator being located at the top of the tower. Summary of the Invention

[0003] The purpose of this invention is to provide a wind power generation tower that can reduce the risks during the installation of wind power generation towers.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A wind power tower includes an outer shell, a screw and a polished rod fixedly connected inside the outer shell, a generator threadedly connected to the screw, the other side of the generator being slidably connected to the polished rod, and a first rotating motor fixedly connected between the lower end of the screw and the outer shell.

[0006] The generator has multiple positioning holes machined on it, and a positioning pin is slidably connected in each positioning hole. A fixing seat is fixed to the multiple positioning pins.

[0007] A fan seat is rotatably connected to the fixed base. A spline groove is machined on the fan seat, and a spline shaft is meshed in the spline groove. The spline shaft is mounted on the generator.

[0008] Three second rotary motors are fixed inside the fan base, and the output shafts of the three second rotary motors are all threaded.

[0009] The fan base is slidably connected to three telescopic pins, and each telescopic pin is fixed to the fan base with a spring.

[0010] Each telescopic pin is fixedly connected to a baffle, and a limiting plate is fixedly connected to the lower side of the fixed seat. The three baffles contact the limiting plate in sequence. Attached Figure Description

[0026] like Figure 1 , 2 As shown:

[0027] A wind power tower has a screw 102 and a polished rod 103 both fixedly connected inside a housing 101. A generator 201 is threadedly connected to the screw 102. The other side of the generator 201 is slidably connected to the polished rod 103. A first rotating motor is fixedly connected between the housing 101 and the lower end of the screw 102.

[0028] When assembling wind turbine towers, the fan blades and fan base 205 are usually assembled at the base of the tower first, and then the assembled fan is hoisted up and assembled with the tower. This operation carries a high risk of damaging the fan and is difficult to install. Therefore, this invention first drives a first rotary motor to rotate, which controls the rotation of a screw 102. A generator 201 is threaded onto the screw 102, and the other side of the generator 201 is slidably connected to a smooth rod 103. By controlling the rotation of the screw 102, the generator 201 is driven to slide up and down within the housing 101. When the generator 201 moves up and down, the smooth rod 103 assists in stabilizing the generator 201 and prevents the generator 201 from rotating on the screw 102. This allows the fan to be assembled onto the generator 201 at the base of the tower, thereby reducing the difficulty and risk of tower assembly.

[0029] like Figure 3-5 As shown:

[0030] The generator 201 has multiple positioning holes 203 machined at one end, and multiple positioning pins 206 are fixedly connected to the fixed base 204. Each positioning hole 203 has a slidably connected positioning pin 206.

[0031] A fan mount 205 is slidably connected to the mounting base 204. The generator 201 moves downwards on the screw 102 as the screw 102 rotates. After the generator 201 reaches the bottom of the power tower, the mounting base 204 is installed onto the generator 201, thus installing the mounting base 204 with the fan mount 205 onto the generator 201. Multiple positioning holes 203 are machined on the mounting surface of the generator 201, and the same number of positioning pins 206 are fixed on the mating surface of the mounting base 204. The positioning pins 206 are aligned with the positioning holes 203, and then the mounting base 204 is moved to synchronously move the positioning pins 206 into the corresponding positioning holes 203, thereby completing the installation of the mounting base 204. Then, the first rotary motor is driven to rotate, causing the screw 102 to drive the generator 201 upwards towards the top of the power tower, thus achieving safe installation of the mounting base 204 and reducing installation risks.

[0032] like Figure 3-5 As shown:

[0033] The fan base 205 is rotatably connected to the fixed base 204. The spline groove 207 is machined on the fan base 205. The spline shaft 202 is mounted on the generator 201. The spline shaft 202 slides in the spline groove 207 and meshes with the spline groove 207.

[0034] When the generator 201 moves to the bottom of the housing 101, a mounting base 204 is installed on the generator 201. The mounting base 204 is installed on the generator 201 through the cooperation of the fixing pin and the fixing hole, and the fan base 205 is rotatably connected to the other end of the mounting base 204. When the mounting base 204 is installed, the spline groove 207 machined on the fan base 205 is engaged with the spline groove 207 installed on the generator 201. Thus, when the wind drives the fan blade to move, the fan blade drives the fan base 205 to rotate on the mounting base 204. Thus, the fan base 205 is engaged with the spline shaft 202 through the spline groove 207, driving the spline shaft 202 to rotate, thereby starting stable wind power generation.

[0035] like Figure 5 As shown:

[0036] Three second rotary motors 209 are fixed inside the fan base 205, and the output shafts of the three second rotary motors 209 are all threaded.

[0037] The fan base 205 is lifted to the top of the outer casing 101, and the spline shaft 202 is rotated, causing the spline shaft 202 to drive the fan base 205 to rotate. This causes one of the second rotary motors 209, which is fixed to the fan base 205, to be vertically downward. At this time, the fan blade is placed vertically with its mounting surface facing upward. The fan blade is lifted and moved upward until the output shaft of the second rotary motor 209 contacts the fan blade, thereby driving the second rotary motor 209 to rotate. This causes the threaded output shaft to be screwed into the fan blade, thus fixing the fan blade. After installing one fan blade, the spline shaft 202 is rotated to rotate the other second rotary motor 209, which does not have a fan blade installed, to be vertically downward. This process is repeated to install the fan blades in sequence. Depending on the wind direction, the second rotary motor 209 can be driven to rotate, thereby changing the angle of the fan blade and maximizing the force-bearing area of ​​the fan blade, thus improving the power generation efficiency of the power generation tower.

[0038] like Figure 7 As shown:

[0039] Three telescopic pins 301 are slidably connected inside the fan base 205, and a spring 302 is fixed between each telescopic pin 301 and the fan base 205.

[0040] The telescopic pin 301 slides within the fan base 205 and extends beyond the fan blade mounting surface of the fan base 205. When the fan blade is installed into the fan base 205, the fan blade gradually presses the telescopic pin 301 into the fan base 205. At the same time, the spring 302 fixed between the telescopic pin 301 and the fan base 205 is compressed, thereby unlocking the fan base 205 and allowing the fan base 205 to rotate on the fixed base 204.

[0041] like Figure 6 As shown:

[0042] Three baffles 303 are fixedly connected to three telescopic pins 301 respectively, and the limiting plate 208 is fixedly connected to the lower side of the fixed base 204. The three baffles 303 contact the limiting plate 208 in sequence.

[0043] Furthermore, a limiting plate 208 is fixedly attached to the lower end of the fixed base 204 to intercept the fan base 205; a baffle 303 is fixedly attached to each telescopic pin 301, extending out of the fan base 205. When the fan base 205 is repositioned, the telescopic pin 301 without fan blades extends out of the fan base 205, so the baffle 303 on the telescopic pin 301 contacts the limiting plate 208 and is intercepted by the limiting plate 208, preventing the fan base 205 from continuing to rotate; when the fan blades are installed on the second rotary motor 209, the fan blades press the telescopic pins 301 into the fan base 205, and at the same time, the telescopic pins 301 move with the baffles 303 towards the rotation center of the fan base 205, so that when the fan base 205 rotates, the baffles 303 can just pass through the notch machined on the limiting plate 208; thus achieving precise positioning when installing the fan blades.

[0044] like Figure 8 As shown:

[0045] Two slide rods 104 are fixed inside the housing 101. The slider is slidably connected between the two slide rods 104. The push rod 304 is rotatably connected to the slider. The other end of the push rod 304 is rotatably connected to the connecting rod 305. The other end of the connecting rod 305 is rotatably connected to the inner wall of the housing 101.

[0046] Two sliding rods 104 are fixed to the bottom of the outer casing 101, allowing the slider to slide between the two sliding rods 104. An electric push rod is fixed to the bottom of the outer casing 101, and the telescopic end of the electric push rod is fixed to one side of the slider. Driving the electric push rod causes the telescopic end of the electric push rod to move the slider. When the slider moves forward, the push rod 304 rotatably connected to the slider moves upward. The other end of the push rod 304 is rotatably connected to a connecting rod 305, and the other end of the connecting rod 305 is rotatably connected to the inner wall of the outer casing 101. Thus, the push rod 304 pushes the connecting rod 305 to flip upward. When the connecting rod 305 flips upward, the end of the connecting rod 305 that is hinged to the push rod 304 moves simultaneously in both the horizontal and vertical directions. A fixing device for the fan blade is installed at the hinge point between the connecting rod 305 and the push rod 304, thereby adjusting the position of the fan blade when the connecting rod 305 moves, so that the mounting port on the fan blade is aligned with the output shaft of the second rotary motor 209, thus facilitating installation.

[0047] like Figure 8 , 9 As shown:

[0048] The locking seat 401 is rotatably connected to the top rod 304 and the connecting rod 305. All four fixing plates 402 are rotatably connected to the locking seat 401. A roller 403 is rotatably connected between two fixing plates 402 on the same side.

[0049] A locking seat 401 is rotatably connected to the connecting rod 305 at the hinge point with the top rod 304. Four fixing plates 402 are rotatably connected to the locking seat 401. Two fixing plates 402 on the same side form a group. A roller 403 is installed on the upper side of the two fixing plates 402 on the same side. The two rollers 403 on both sides contact the two end faces of the fan blade. The fan blade is generally wider at the top and narrower at the bottom. Therefore, after the fan blade is placed between the two rollers 403, the fan blade slides downward relative to each other. The center distance between the two rollers 403 is gradually increased by the fan blade, which increases the angle between the two groups of fixing plates 402 with the rollers 403 rotating respectively. Both fixing plates 402 on both sides rotate on the locking seat 401. Thus, the fixing plates 402 rotate around the locking seat 401. The distance between one end increases and the distance between the other end gradually decreases. Therefore, the greater the distance the fan blade slides between the two rollers 403, the more firmly the fan blade is clamped. Self-locking is achieved by relying on the weight of the fan blade.

[0050] like Figure 9 As shown:

[0051] A friction block 404 is fixed between two fixed plates 402 on the same side. The friction block 404 is semi-cylindrical. Due to the weight of the fan blade, the end of the fixed plate 402 with the roller 403 is opened, thereby reducing the distance of the end with the friction block 404 and the distance between the two friction blocks 404, thus firmly clamping the fan blade. The friction block 404 is set as semi-cylindrical to adapt to different angles, so that the friction block 404 can better contact the surface of the fan blade, thereby providing stable friction to fix the fan blade.

[0052] like Figure 10 As shown:

[0053] Two protective plates 105 are slidably connected to both sides of the outer casing 101. After the fan blades are installed, the two protective plates 105 are driven to slide from both sides of the outer casing 101 toward the front of the outer casing 101 until the two protective plates 105 come into contact with each other and close tightly, so that the two protective plates 105 and the outer casing 101 together form a cylindrical outer surface, thereby protecting the internal electrical structure of the power generation tower in rain and snow environments. The closure of the two protective plates 105 forms a smooth transition surface, reducing the wind resistance coefficient, so that the power generation tower can still operate safely and stably in strong wind environments.
