[0025] like Figure 1 As shown, the signal tower wind power generation device includes a base 1, a wind rotor mechanism 3 and a generator 2. The wind rotor mechanism 3 and the generator 2 are both installed on the base 1, and the base 1 is installed on the signal tower. The wind rotor mechanism 3 can capture wind energy and convert the wind energy into mechanical energy to drive the generator 2 to generate electricity, and the electricity generated by the generator 2 is used to power the signal tower.

[0026] like Figure 2As shown, the present invention has a guide column 5 installed on the machine base 1 (the guide column 5 is specifically installed on the gear box 8, and the gear box 8 is installed on the machine base 1), the wind wheel mechanism 3 is installed on the wheel hub 1, and the wheel hub 1 is rotatably installed on the guide column 5 through a bearing (the guide column 5 passes through the wheel hub 1 and is located at the center of the wheel hub 1), and a transmission gear 41 is installed on the wheel hub 4. In addition, a speed-increasing gear mechanism is installed on the machine base 1 (the speed-increasing gear mechanism is installed in the gear box), and the input end of the speed-increasing gear mechanism is transmission-connected with the transmission gear 41, and the output end of the speed-increasing gear mechanism is transmission-connected with the generator 2. Under the action of wind force, the wind wheel mechanism 3 drives the wheel hub 4 to rotate, and the transmission gear 41 on the wheel hub 4 drives the speed-increasing gear mechanism, and the speed-increasing gear mechanism drives the generator 2 to generate electricity after speeding up.

[0027] like Figure 2 As shown, the speed-increasing gear mechanism includes a gearbox, and a first-stage speed-increasing gear assembly, a second-stage speed-increasing gear assembly and a third-stage speed-increasing gear assembly installed in the gearbox. The first-stage speed-increasing gear assembly includes a first-stage rotating shaft 12, a first-stage pinion 10 and a first-stage large gear 11, and the first-stage pinion 10 and the first-stage large gear 11 are installed on the first-stage rotating shaft 12. The second-stage speed-increasing gear assembly includes a second-stage rotating shaft 14, a second-stage pinion 13 and a second-stage large gear 15, and the second-stage pinion 13 and the second-stage large gear 15 are installed on the second-stage rotating shaft 14. The third-stage speed-increasing gear assembly includes a third-stage rotating shaft 17, a third-stage pinion 16 and a third-stage large gear 18, and the third-stage pinion 16 and the third-stage large gear 18 are installed on the third-stage rotating shaft 17. The first-stage pinion 10 is meshed with the transmission gear 41, the first-stage large gear 11 is meshed with the second-stage pinion 13, the second-stage large gear 15 is meshed with the third-stage pinion 16, and the third-stage large gear 18 is meshed with the input gear 19 installed on the output main shaft 20, and the output main shaft 20 is transmission-connected to the generator 2.

[0028] When the wheel hub 4 rotates, the transmission gear 41 drives the first-stage pinion 10 to rotate, and the first-stage large gear 11 rotates at the same time. The linear speed of the first-stage large gear 11 is greater than that of the first-stage pinion 10, so a first speed increase is obtained; the first-stage large gear 11 drives the second-stage pinion 13, and the second-stage large gear 15 rotates at the same time. The linear speed of the second-stage large gear 15 is greater than that of the second-stage pinion 13, so a second speed increase is obtained; the second-stage large gear 15 drives the third-stage pinion 16, and the third-stage large gear 18 rotates at the same time. The linear speed of the third-stage large gear 18 is greater than that of the third-stage pinion 16, so a third speed increase is obtained; finally, the third-stage large gear 18 drives the output main shaft 20 to rotate, and the output main shaft 20 drives the generator 2 to do work and generate electricity.

[0029] like Figure 3As shown, the gearbox 8 has a gearbox bottom plate 81 and a gearbox cover plate 80, and the guide column 5 is arranged at the center of the gearbox cover plate 80 (the guide column 5 and the gearbox cover plate 80 can be designed as an integral body, or can be designed separately by flange connection). In order to better optimize the internal structure of the gearbox 8, reduce the volume of the gearbox 8, and reduce the friction coefficient between transmissions, the present invention is provided with a support seat 7 on the gearbox bottom plate 81, the secondary rotating shaft 14 is connected between the gearbox cover plate 80 and the support seat 7 through a bearing, the primary rotating shaft 12 is connected between the gearbox bottom plate 81 and the gearbox cover plate 80 through a bearing, the tertiary rotating shaft 17 is connected between the gearbox bottom plate 81 and the gearbox cover plate 80 through a bearing, the secondary rotating shaft 14 is located between the primary rotating shaft 12 and the tertiary rotating shaft 17, the output main shaft 20 is installed at the center of the support seat 7 through a bearing, and the output main shaft 20, the secondary rotating shaft 14 and the guide column 5 are kept coaxial. Since the secondary rotating shaft 14 is located between the primary rotating shaft 12 and the tertiary rotating shaft 17, the internal space of the gear box 8 is utilized to the maximum extent, reducing the volume and weight of the gear box 8. At the same time, the setting of the support seat 7 can make the installation of the output main shaft 20 and the installation of the secondary rotating shaft 14 coaxial with the guide column 5, which further improves the utilization rate of the internal space of the gear box 8, further reduces the volume and weight of the gear box 8, greatly reduces wind resistance, greatly increases stability, and reduces manufacturing costs. The setting of the bearing can reduce the friction coefficient between transmissions and improve power generation efficiency.

[0030] like Figure 4 As shown, the wind wheel mechanism 3 includes a plurality of wind blade units, and the wind blade unit includes a wind blade arm 30 and a wind blade 31 installed on the wind blade arm 30. Figure 5As shown, the fan blade 31 includes two upper and lower cover plates 310, two curved fixed side plates 311 and two curved movable side plates 312. The two curved fixed side plates 311 are fixedly connected between the upper and lower cover plates 310. A ventilation opening is formed between the two curved fixed side plates 311. One curved movable side plate 312 is hinged to one curved fixed side plate 311, and the other curved movable side plate 312 is hinged to the other curved fixed side plate 311. The two curved movable side plates 312 have an open state in which they are opened to form a ventilation opening, and a closed state in which they are closed to form a circular arc surface with the two curved fixed side plates 311. This wind blade structure is very clever: when the windward side of the wind blade faces the wind direction, the two curved movable side panels 312 are closed under the action of wind force, and form a closed state of the arc surface with the two curved fixed side panels 311 (forming a semi-cylindrical shape), that is, the windward side forms a semi-circular spiral wind cavity, which greatly increases the concentrated thrust of the wind when receiving wind, and the efficiency is maximized. At the same time, the outer curved surface can minimize wind resistance; when the leeward side of the wind blade faces the wind direction, the two curved movable side panels 312 are naturally opened under the action of wind force, and the wind flows through the ventilation opening between the two curved fixed side panels 311 (at this time, the direction of the wind blade remains unchanged), so that the wind blade 31 can minimize resistance. Through this structure, wind force can be captured to the maximum extent, and wind resistance can be minimized at the same time. This wind wheel mechanism 3 is suitable for use in light wind areas, and the application engineering of light wind power generation is completed by closing and opening the wind blade.

[0031] As described above, the curved movable side panel 312 is hinged to the curved fixed side panel 311, specifically, it is hinged to the curved fixed side panel through a hinge. Figure 6 and Figure 7 As shown, the hinge has a pin shaft 315, a movable leaf 316 and a fixed leaf 317, the movable leaf 316 is connected to the curved movable side plate 312, and the fixed leaf 317 is connected to the curved fixed side plate 311. In order to make the curved movable side plate 312 have a damping effect during the rotation process, the present invention is provided with a corrugated pad 318 and a wear-resistant sheet 319 on the pin shaft 315, and the corrugated pad 318 and the wear-resistant sheet 319 are squeezed between the movable leaf 316 and the fixed leaf 317. The corrugated pad 318 is elastic, so that the wear-resistant sheet 319 is squeezed between the movable leaf 316 and the fixed leaf 317, so that resistance is generated between the movable leaf 316 and the fixed leaf 317, so that the curved movable side plate 315 can rotate slowly and reduce noise.

[0032] Of course, in order to limit the rotation of the curved movable side plate 312 within the setting range as described above, Figure 5As shown, the fan blade 31 also has an outer magnetic limiting member 313 and an inner magnetic limiting member 314. The opening and closing of the two curved movable side plates 312 are restricted by the outer magnetic limiting member 313 and the inner magnetic limiting member 314. The outer magnetic limiting member 313 and the inner magnetic limiting member 314 can both attract the curved movable side plates 312, so that the curved movable side plates 312 will not shake.

[0033] To protect signal towers from lightning strikes, Figure 2 As shown, the guide column 5 of the present invention passes through the wheel hub 4, and a lightning rod 6 is installed at the upper end of the guide column 5 (there are two ways to connect the lightning rod 6 to the guide column 5. The low-power one can use a top screw to support the guide column on the side of the bottom of the lightning rod, while the high-power one can be installed by screws from bottom to bottom through a flange connection). In addition, the guide column 5 has a wire hole 50, and the grounding wire of the lightning rod 6 is connected to the ground through the wire hole 50.

[0034] In order to prevent rainwater from entering the wheel hub 4, the present invention provides a waterproof boss 40 on the wheel hub 4, and the lower part of the connecting seat 60 of the lightning rod 6 covers the waterproof boss 40. The connecting seat 60 of the lightning rod 6 can prevent rainwater from falling directly into the wheel hub 4, and the waterproof boss 40 on the wheel hub 4 can prevent rainwater on the surface of the wheel hub 4 from flowing into the wheel hub 4.

[0035] The present invention also provides another wind wheel mechanism, such as Figure 8 and Fig. 9 As shown, the wind wheel mechanism includes a wind wheel arm 32, a wind slot 33 and a wind wheel blade 34. The wind wheel blade 34 is rotatably installed in the wind slot 33 (the wind slot 33 is hemispherical, the windward surface is concave, which can capture greater wind force, and the back surface is a curved surface, which can greatly reduce wind resistance). The wind slot 33 is installed on the wind wheel arm 32 (as shown in FIG. Fig.10 As shown, the back of the wind wheel arm 32 is also a curved surface, which is the same as the principle of the wind slot 33 and can also reduce wind resistance). The wind slot 33 and the wind wheel arm 32 have an air outlet channel 330. Figure 8 As shown, during operation, wind enters the wind slot 33 and drives the wind wheel blades 34 to rotate, then enters from the air inlet on the wind slot 33, flows through the air outlet channel 330, and finally exits from the air outlet of the wind wheel arm 32, so that the wind wheel mechanism can rotate.

[0036] This type of wind rotor mechanism is suitable for use in windy areas and risk areas with typhoons. When typhoon weather is needed, in order to protect the wind rotor mechanism from being affected, the wind rotor arm 32 is rotatably and adjustably mounted on the hub 4. In addition, a small motor 39 is mounted on the inner side of the hub 4, and the wind rotor arm 32 is in transmission connection with the small motor 39. When not working, the small motor 39 is used to achieve horizontal placement of the wind rotor mechanism through multi-stage reduction (low output speed, high output torque) (the whole process is completed through new electronic control technology), that is, the concave surface of the wind slot 33 faces downward, and the arc surface of the wind slot 33 faces upward, so that the wind force only acts on the arc surface of the wind slot 33, and the forces in all directions are the same, so that the wind slot 33 will not rotate and is in a stopped state, thereby avoiding being affected by the typhoon.

[0037] The small motor 39 requires electricity to work. In order to power the small motor 39, the wind wheel mechanism 3 includes a small generator 38. The wind wheel blades 34 are transmission-connected to the small generator 38. The rotation of the wind wheel blades 34 drives the small generator 38 to generate electricity, and the small generator 38 thus powers the small motor 39.
