Technical Field

[0001] The present invention belongs to the technical field of auxiliary power generation, and more specifically relates to an auxiliary power generation device based on external rotation power. Background Art

[0002] Central air conditioning or central ventilation systems are generally installed in places such as constant temperature and humidity factories, airports, high-speed railway stations or highway service areas, requiring the use of a variety of cooling fans or ventilation fans. During operation, the above fans will discharge gas with stable flow rate and flow. At present, this part of the gas is partially utilized for wind power generation, but its utilization efficiency is poor and the power generation is low.

[0003] The use effect of traditional auxiliary power generation devices is poor, which makes the fan airflow easily overflow when discharged, so that the airflow cannot fully act on the fan blades of the auxiliary power generation device, reducing the effect of the auxiliary power generation device. Secondly, the loss of non-contact transmission is large, which reduces the power generation effect of the auxiliary power generation device; at the same time, the traditional auxiliary power generation device does not have an auxiliary docking structure, and the end diameters of fans of different models are different. The traditional auxiliary power generation device cannot be used for fan structures of different diameters, thereby reducing the scope of application of the auxiliary power generation device. Summary of the invention

[0008] The purpose of the present invention can be achieved through the following technical solutions:

[0009] An auxiliary power generation device based on external rotation power includes a generator and a guide tube, wherein the guide tube is movably installed on one side of the generator, a rotating shaft is provided in the middle of the generator, a second fan blade for driving the rotating shaft is provided on the inner side of the guide tube, when the second fan blade adopts non-contact transmission, a fan is provided on one side of the second fan blade, when the second fan blade adopts contact transmission, a transmission assembly is provided between the second fan blade and the fan, the transmission assembly includes a driven gear and a driving gear, the number of the driven gears is several groups, the several groups of driven gears are all around the outer surface of the driving gear, the driven gears and the driving gears are meshed with each other, the several groups of driven gears are connected by planetary carriers, and a docking clamp ring is provided between the fan and the guide tube.

[0010] As a further technical solution of the present invention, the second fan blade is fixedly mounted on one end of the rotating shaft, and the first fan blade is provided at the other end of the rotating shaft. An electromagnetic clutch is provided between the rotating shaft and the first fan blade. When the direction in which the natural wind drives the first fan blade to rotate is the same as the direction in which the second fan blade needs to rotate, the electromagnetic clutch is engaged, so that the rotation of the first fan blade drives the rotating shaft to rotate, providing assistance for power generation. When the direction in which the natural wind drives the first fan blade to rotate is opposite to the direction in which the second fan blade needs to rotate, the electromagnetic clutch is disconnected, and the rotation of the first fan blade will not drive the rotating shaft of the generator to rotate, thereby avoiding the natural wind from hindering the power generation of the generator.

[0011] As a further technical solution of the present invention, a gear ring is provided on the outer surface of the driven gear, the driven gear and the gear ring are meshed with each other, a shell is provided on the outside of the gear ring, and the driving gear is docked at the shaft of the fan. When the fan is running, the fan drives the driving gear to rotate through the shaft, and the driving gear cooperates with the gear ring to drive the driven gear, so that the driven gear drives the planetary carrier, and the rotating shaft is driven through the planetary carrier, thereby enabling the generator to generate electricity.

[0012] As a further technical solution of the present invention, the outer surface of one end of the guide tube is a sloped structure, a guide plate is fixedly installed on the inner side of the other end of the guide tube, a baffle is fixedly installed on the outer surface of the other end of the guide tube, and an exhaust port is provided on the outer surface of the guide tube on one side of the baffle. When the blades in the fan rotate, the second blades are directly driven by the fan, so that the second blades drive the rotating shaft to rotate. At the same time, the guide tube with the sloped structure can enhance the rotation effect of the second blades, and the excess gas in the guide tube is discharged from the exhaust port through the guide plate and the baffle.

[0013] As a further technical solution of the present invention, a splicing inner ring is sleeved on the inner side of the docking clamp, and the inner side of the docking clamp is a double thread structure.

[0015] Beneficial effects of the present invention:

[0016] 1. When the auxiliary power generation device based on external rotation power is used, the guide tube and the fan are connected by a connecting clamp ring. When the fan is running, the gas discharged by the fan blades flows into the guide tube, and then contacts the second fan blades of the wind power generation device, driving the second fan blades of the wind power generation device to rotate. Due to the setting of the guide tube, the gas discharged by the fan blades can be prevented from escaping, so that the discharged gas can be more fully utilized, thereby improving the efficiency and power generation of the power generation;

[0017] Secondly, the user can install a transmission assembly between the fan and the second blade. When the fan blades rotate to perform exhaust operation, the rotation of the fan shaft can drive the generator shaft to rotate through the transmission component. The fan drives the active gear to rotate through the shaft body, so that the active gear cooperates with the ring gear to drive the driven gear, and the driven gear drives the planetary carrier, and the rotating shaft is driven by the planetary carrier, so that the generator can generate electricity. At the same time, the wind discharged by the fan blades will also drive the second blade of the generator to rotate. The cooperation of the two is used to realize the power generation process. The rotation of the fan shaft drives the rotating shaft of the generator to rotate. At the same time, the gas discharged by the fan blades drives the second blade of the generator to rotate. By setting up a transmission assembly, the power generation effect of the generator can be effectively improved. A guide tube is provided between the fan blades and the second blades, and the guide tube cover is made on the outside of the transmission component. In this way, the gas discharged by the fan blades will flow inside the guide tube, thereby making more gas available and thus increasing the power generation.

[0018] 2. By providing a docking clamp ring, when installing the auxiliary power generation device based on external rotational power, the user can choose to install a spliced ​​inner ring of corresponding size according to the caliber of the fan end by using the threaded structure on the inner side of the docking clamp ring, and at the same time use the buckle on the inner side of the spliced ​​inner ring to dock and fix the spliced ​​inner ring and the fan end, thereby completing the docking operation between the auxiliary power generation device and the fan.

DETAILED DESCRIPTION

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0027] like Figure 1 , Figure 2 As shown, an auxiliary power generation device based on external rotation power includes a generator 3 and a guide tube 11. The guide tube 11 is movably installed on one side of the generator 3. A rotating shaft 4 is provided in the middle of the generator 3. The rotor of the generator 3 is driven to rotate by the rotating shaft 4. A second fan blade 10 for driving the rotating shaft 4 is provided on the inner side of the guide tube 11. When the second fan blade 10 adopts non-contact transmission, a fan 7 is provided on one side of the second fan blade 10. The diameter of one end of the guide tube 11 is smaller than the diameter of the other end thereof. When the second fan blade 10 adopts contact transmission, a transmission component 13 is provided between the second fan blade 10 and the fan 7. The two ends of the guide tube 11 are the same size.

[0028] like Figure 3 , Figure 4 As shown, the transmission assembly 13 includes a driven gear 17 and a driving gear 18. The number of the driven gears 17 is several groups. The planet carrier 15 can be driven by using several groups of driven gears 17. The several groups of driven gears 17 are all around the outer surface of the driving gear 18. The driven gears 17 and the driving gears 18 are meshed with each other. The several groups of driven gears 17 are connected through the planet carrier 15. A docking clamp 12 is provided between the fan 7 and the guide tube 11.

[0029] like Figure 1 As shown, the second fan blade 10 is fixedly mounted on one end of the rotating shaft 4, and the other end of the rotating shaft 4 is provided with a first fan blade 8. An electromagnetic clutch 5 is provided between the rotating shaft 4 and the first fan blade 8. When the direction in which the natural wind drives the first fan blade 8 to rotate is the same as the direction in which the second fan blade 10 needs to rotate, the electromagnetic clutch 5 is attracted, so that the rotation of the first fan blade 8 drives the rotating shaft 4 to rotate, providing assistance for power generation. When the direction in which the natural wind drives the first fan blade 8 to rotate is opposite to the direction in which the second fan blade 10 needs to rotate, the electromagnetic clutch 5 is disconnected, and the rotation of the first fan blade 8 will not drive the rotating shaft 4 of the generator 3 to rotate, thereby avoiding the natural wind from hindering the power generation of the generator 3.

[0030] Example 1

[0031] like Figure 2 As shown, when the second fan blade 10 adopts contact transmission, the outer surface of the driven gear 17 is provided with a ring gear 16, and the driven gear 17 and the ring gear 16 are meshed with each other. The outside of the ring gear 16 is provided with a shell 14, and the driving gear 18 is docked at the shaft of the fan 7. When the fan 7 is running, the fan 7 drives the driving gear 18 to rotate through the shaft, and the driving gear 18 cooperates with the ring gear 16 to drive the driven gear 17, so that the driven gear 17 drives the planetary carrier 15, and drives the rotating shaft 4 through the planetary carrier 15, so that the generator 3 performs power generation operation.

[0032] Example 2

[0033] like Figure 1 As shown, when the second fan blade 10 adopts non-contact transmission, the outer surface of one end of the guide tube 11 is a sloped structure, and a guide plate 2 is fixedly installed on the inner side of the other end of the guide tube 11, and a baffle 1 is fixedly installed on the outer surface of the other end of the guide tube 11. An exhaust port 9 is provided on the outer surface of the guide tube 11 on one side of the baffle 1. When the blades in the fan 7 rotate, the second fan blade 10 is directly driven by the fan 7, so that the second fan blade 10 drives the rotating shaft 4 to rotate. At the same time, the guide tube 11 with the sloped structure can enhance the rotation effect of the second fan blade 10, and the excess gas in the guide tube 11 is discharged from the exhaust port 9 through the guide plate 2 and the baffle 1.

[0034] like Figure 5As shown, a splicing inner ring 19 is sleeved on the inner side of the docking clamp 12. By replacing the splicing inner ring 19, the user can make the replaced splicing inner ring 19 suitable for fan 7 structures with different calibers. The inner side of the docking clamp 12 is a double-threaded structure. The double-threaded structure on the inner side of the docking clamp 12 can be used to dock and fix the splicing inner ring 19 and the guide tube 11 respectively. A buckle is provided on the inner side of the splicing inner ring 19. The splicing inner ring 19 can be fixed to the end of the fan 7 through its buckle-type fixing structure, thereby completing the docking and fixing operation of the fan 7. The user can choose to install a splicing inner ring 19 of corresponding size according to the caliber of the end of the fan 7 by using the threaded structure on the inner side of the docking clamp 12, and fix the end of the fan 7 through the splicing inner ring 19.

[0035] like Figure 1 As shown, the middle parts of the first fan blade 8 and the second fan blade 10 are both provided with a fixing sleeve 6 for docking with the rotating shaft 4, and the first fan blade 8 and the second fan blade 10 are both four-blade structures.

[0036] like Figure 2 As shown, when the second fan blade 10 adopts contact transmission, the guide tube 11 is a tubular structure, and an adjustment ring 20 is movably sleeved on the outer surface of the guide tube 11.

[0037] The surfaces of the guide tube 11 and the adjustment ring 20 are both annular and have a plurality of exhaust grooves therethrough. The size of the exhaust grooves can be controlled by rotating the adjustment ring 20 , thereby regulating the wind force in the guide tube 11 .

[0038] The auxiliary power generation device based on external rotational power, when in use, the guide tube 11 and the fan 7 are docked by the docking clamp ring 12. When the fan 7 is running, the gas discharged by the fan blades flows into the guide tube 11, and then contacts the second fan blades 10 of the wind power generation device, driving the second fan blades 10 of the wind power generation device to rotate. Due to the setting of the guide tube 11, the gas discharged by the fan blades can be prevented from escaping, so that the discharged gas can be more fully utilized, thereby improving the efficiency and power generation of the power generation;

[0039] Secondly, the user can add a transmission assembly 13 between the fan 7 and the second blade 10. When the blades of the fan 7 rotate to perform exhaust operation, the rotation of the shaft of the fan 7 can drive the shaft of the generator 3 to rotate through the transmission assembly 13. The fan 7 drives the driving gear 18 to rotate through the shaft body, so that the driving gear 18 cooperates with the ring gear 16 to drive the driven gear 17, so that the driven gear 17 drives the planetary carrier 15, and the rotating shaft 4 is driven through the planetary carrier 15, so that the generator 3 performs power generation operation; at the same time, the wind discharged by the fan blades will also drive the second blade 10 of the generator 3 to rotate. The power generation process is realized by the cooperation of the two. The rotation of the shaft of the fan 7 drives the rotating shaft 4 of the generator 3 to rotate. At the same time, the gas discharged by the fan blades drives the second blade 10 of the generator 3 to rotate. By setting the transmission assembly 13, the power generation effect of the generator 3 can be effectively improved. A guide tube 11 is provided between the fan blade and the second blade 10, and the guide tube 11 is covered on the outside of the transmission component, so that the gas discharged by the fan blades will flow inside the guide tube 11, thereby making more gas available, thereby making the power generation larger;

[0040] By providing the docking clamp 12, when installing the auxiliary power generation device based on external rotational power, the user can choose to install a splicing inner ring 19 of a corresponding size according to the caliber of the end of the fan 7 by utilizing the threaded structure on the inner side of the docking clamp 12, and at the same time utilize the buckle on the inner side of the splicing inner ring 19 to dock and fix the splicing inner ring 19 and the end of the fan 7, thereby completing the docking operation between the auxiliary power generation device and the fan 7. By replacing splicing inner rings 19 of different sizes, it can be suitable for fans 7 of different calibers, thereby improving its scope of application.
