The curtain wall assembly includes a connecting frame, a rectangular frame, curtain wall glass and a photovoltaic panel, wherein the connecting frame is fixed to the bottom outer wall of the cantilever arm by bolts, the rectangular frame is fixed to the inner side of the connecting frame, and a sealing flexible gasket is provided at the gap between the connecting frame and the rectangular frame, the curtain wall glass is fixed to the front side of the inner wall of the rectangular frame, the photovoltaic panel is fixed to the rear side of the inner wall of the rectangular frame, and the power generation terminal of the photovoltaic panel is electrically connected to a battery pack; The cantilever arm includes a fixed support frame fixed to the outer wall of the building, a cantilever rotatably connected to the fixed support frame via a second main shaft, and a drum rotatably connected to the fixed support frame via a first main shaft. The connecting frame is fixed to the bottom outer wall of the cantilever by bolts, and a support leaf spring for supporting the cantilever is fixed to the inner side of the fixed support frame.

[0008] Preferably: a rope buckle is fixed above the end of the cantilever by a bolt, a pull rope is fixed to the outer wall of the rope buckle, and the other end of the pull rope is wound around and fixed to the outer wall of the drum.

[0009] Furthermore: a fixing ring is fixed on the outer wall of the fixed support frame, and a torsion spring is buckled on the inner side of the fixing ring and the outer side of the main shaft.

[0010] On the basis of the above scheme: the outer wall of the fixed support frame is fixed with a generator by bolts, the main shaft one and the main shaft two are matched with the input shaft of the generator through the same set of speed increase and range increase components, and the output terminal of the generator is electrically connected to the input terminal of the battery pack through the current reversing component.

[0011] A better solution among the above solutions is: the current reversing component includes a "U"-shaped frame fixed to the outer wall of the fixed support frame and a slider slidably connected to the inner side of the "U"-shaped frame through a guide rod, the inner wall of the slider is fixed with two reversing electrodes, the two reversing electrodes are electrically connected to the positive and negative electrodes of the battery pack, one side of the "U"-shaped frame is fixed with electrode 2 A and electrode 2 B respectively opposite to the two reversing electrodes, and the other side of the two "U"-shaped frames is fixed with electrode 1 A and electrode 1 B respectively opposite to the two reversing electrodes.

[0013] At the same time, a permanent magnet is fixed on the inner wall of the slider, an electromagnet matched with the permanent magnet is fixed on the inner wall of the "U"-shaped frame, and the electromagnet is connected in parallel with the stator winding of the generator.

[0014] As a preferred embodiment of the present invention: the speed increasing and range increasing assembly includes an outer ring gear, a sun gear and a gear, the outer ring gear is fixed to the outer wall of the main shaft one, the sun gear is rotatably connected to the outer wall of the main shaft one, and a plurality of planetary gears are meshed on the opposite side of the outer ring gear and the sun gear, and the side walls of the plurality of planetary gears are rotatably connected to the same planetary gear carrier.

[0015] At the same time, the gear is fixed to the outer wall of the second main shaft, and the gear is meshed with the outer wall of the planetary gear carrier.

[0016] As a more preferred solution of the present invention: a connecting ring is fixed to one side of the sun gear, and the connecting ring is matched with the input shaft of the generator through the transmission of the synchronous assembly.

[0017] The beneficial effects of the present invention are: 1. The present invention, by configuring the curtain wall assembly as a combination of curtain wall glass and photovoltaic panels, utilizes the light transmittance of the curtain wall glass and the photoelectric conversion characteristics of the photovoltaic panels, and designs the positions of the curtain wall glass and the photovoltaic panels, thereby ensuring that the curtain wall glass is within the observable field of view to provide decorative performance on the one hand, and can also recycle solar energy through the photovoltaic panels to achieve energy saving on the other hand.

[0018] 2. In the present invention, based on the arrangement of a relatively movable cantilever, the load of the cantilever on the connecting frame is provided jointly by a supporting leaf spring and a torsion spring. Thus, on the one hand, the whole is in a flexible support, which can provide a certain amount of up and down vibration / swing absorption and increase the service life. On the other hand, since the load of the cantilever on the cantilever is downward and the pulling force of the pull rope on the cantilever is obliquely upward, the oblique upward pulling force can be used to longitudinally separate and offset part of the downward load, so that the longitudinal load of the cantilever is shared in the length direction of the cantilever to prevent deformation due to bending moment.

[0019] 3. The present invention, on the basis of setting a soft support for the connecting frame, sets structures such as a generator and a current reversing assembly, thereby, on the one hand, utilizing the up and down vibration / swinging motion of the connecting frame to absorb energy and convert it into electrical energy storage, thereby further achieving energy-saving effects; on the other hand, when the generator is converting energy, it will also reversely suppress the vibration / swing of the connecting frame, thereby reducing its amplitude / swing amplitude and ensuring safety.

[0020] 4. The present invention utilizes the staggered electrode arrangement of electrode 1A, electrode 1B, electrode 2A, and electrode 2B, so that the positive-to-positive and negative-to-negative connection reliability of the generator and the battery pack can be achieved by utilizing the movement of the slider. In addition, by utilizing the different directions of the electromotive force of the stator winding at different times of the generator rotation, combined with electromagnetic conversion, the automatic drive control of the slider movement is realized, achieving the purpose of self-induction and self-drive.

[0021] 5. The present invention, by setting a speed-increasing and range-increasing component, adopts a dual-input drive form on the basis of using a "planetary gear set" to increase the speed, and combines the same direction of rotation of the main shaft one and the main shaft two when the cantilever swings, so that the final rotation angle and speed of the sun gear can be a superposition of the ratio of the rotation angle and speed of the main shaft one and the main shaft two, thereby increasing the rotation range and speed of the generator and increasing the energy recovery efficiency.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] Embodiment 1: An energy-saving curtain wall structure with energy recovery, such as Figure 1 - Figure 8 As shown, it includes a cantilever arm 1 and a curtain wall assembly 2 fixed to the bottom of the cantilever arm 1.

[0027] The curtain wall assembly 2 includes a connecting frame 3, a rectangular frame 5, a curtain wall glass 6 and a photovoltaic panel 7. The connecting frame 3 is fixed to the bottom outer wall of the cantilever arm 1 by bolts, the rectangular frame 5 is fixed to the inner side of the connecting frame 3, and a sealing flexible gasket 4 is provided at the gap between the connecting frame 3 and the rectangular frame 5. The curtain wall glass 6 is fixed to the front side of the inner wall of the rectangular frame 5, and the front side is facing the outside of the building, that is, the sunny side. The photovoltaic panel 7 is fixed to the rear side of the inner wall of the rectangular frame 5, and the power generation terminal of the photovoltaic panel 7 is electrically connected to the battery pack 38.

[0028] The cantilever arm 1 includes a fixed support frame 17 fixed to the outer wall of the building, a cantilever 8 rotatably connected to the fixed support frame 17 via a second main shaft 16, and a drum 12 rotatably connected to the fixed support frame 17 via a first main shaft 11. The connecting frame 3 is fixed to the bottom outer wall of the cantilever 8 by bolts, and a support leaf spring 18 for supporting the cantilever 8 is fixed to the inner side of the fixed support frame 17.

[0029] When the device is in use, the cantilever arm 1 can support the curtain wall assembly 2, and during the support, since the connecting frame 3 applies downward pressure to the cantilever 8, and the cantilever 8 rotates with the fixed support frame 17, the load of the cantilever 8 is provided by the supporting leaf spring 18, which is relatively flexible and has a certain buffering capacity. At the same time, the curtain wall glass 6 located on the front side plays a decorative role. At the same time, due to the light transmittance of the curtain wall glass 6, sunlight can penetrate the curtain wall glass 6 to irradiate the photovoltaic panel 7, and then be transmitted to the battery pack 38 for energy storage after photoelectric conversion.

[0030] The device, by configuring the curtain wall assembly 2 as a combination of curtain wall glass 6 and photovoltaic panels 7, utilizes the light transmittance of the curtain wall glass 6 and the photoelectric conversion characteristics of the photovoltaic panels 7, and designs the positions of the curtain wall glass 6 and the photovoltaic panels 7, thereby ensuring that the curtain wall glass 6 is within the observable field of view to provide decorative performance on the one hand, and can also recycle solar energy through the photovoltaic panels 7 to achieve energy saving on the other hand.

[0031] To solve the support problem; Figure 3 As shown, a rope buckle 9 is fixed above the end of the cantilever 8 by bolts, a pull rope 10 is fixed to the outer wall of the rope buckle 9, and the other end of the pull rope 10 is wound around and fixed to the outer wall of the drum 12.

[0032] A fixing ring 19 is fixed to the outer wall of the fixing support frame 17 , and a torsion spring 20 is buckled on the inner side of the fixing ring 19 and the outer side of the main shaft 11 .

[0033] The connecting frame 3 applies a load to the cantilever 8. The rotational torque generated by the cantilever 8 can be provided by the support of the support leaf spring 18 on the one hand, and on the other hand, the rotational torque applied to the drum 12 by the torsion spring 20 is applied to the pull rope 10 and realized by the tension of the pull rope 10.

[0034] In this device, a relatively movable cantilever 8 is provided, and the load of the cantilever 8 on the connecting frame 3 is provided by the supporting leaf spring 18 and the torsion spring 20. On the one hand, the whole is in a flexible support, which can provide a certain amount of up and down vibration / swing absorption and increase the service life. On the other hand, since the load of the connecting frame 3 on the cantilever 8 is downward, and the pulling force of the pull rope 10 on the cantilever 8 is obliquely upward, the oblique upward pulling force can be used to longitudinally separate and offset part of the downward load, so that the longitudinal load of the cantilever 8 is shared in the length direction of the cantilever 8 to prevent deformation due to bending moment.

[0035] At the same time, since the weight of the entire connecting frame 3 is relatively large, and the connecting frame 3 is not subjected to other forces except random wind force and vibration of the building itself during the cantilevering process, the vibration / swing amplitude thereof will not be too large.

[0036] In order to solve the problem of up and down vibration / swing energy absorption; Figure 3 As shown, the outer wall of the fixed support frame 17 is fixed with a generator 14 by bolts, and the main shaft 11 and the main shaft 2 16 are coupled to the input shaft of the generator 14 through the same group of speed increase and range increase components 13, and the output terminal of the generator 14 is electrically connected to the input terminal of the battery pack 38 through the current reversing component 15.

[0037] When the connecting frame 3 swings, the cantilever 8 will rotate to a certain extent, so that the main shaft 11 and the main shaft 2 16 will rotate at a certain angle, thereby driving the generator 14 to rotate through the speed increase and range increase component 13, and the generator 14 converts mechanical energy into electrical energy and stores energy in the battery pack 38.

[0038] This device, on the basis of setting the soft support of the connecting frame 3, is provided with structures such as a generator 14 and a current reversing component 15. On the one hand, it utilizes the up and down vibration / swinging movement of the connecting frame 3 to absorb energy and convert it into electrical energy storage, thereby further achieving energy saving effect. On the other hand, when the generator 14 is converting energy, it will also reversely suppress the vibration / swing of the connecting frame 3, thereby reducing its amplitude / swing amplitude and ensuring safety.

[0039] Since the movement of the connecting frame 3 is reciprocating up and down, the current generated in the generator 14 is also alternating positive and negative, and the charging current of the battery pack 38 needs to be positive to positive and negative to negative, so in order to solve the problem of current direction switching; Figure 5 , 8As shown, the current reversing assembly 15 includes a "U"-shaped frame 21 fixed to the outer wall of the fixed support frame 17 and a slider 26 slidably connected to the inner side of the "U"-shaped frame 21 through a guide rod 28. Two reversing electrodes 22 are fixed to the inner wall of the slider 26. The two reversing electrodes 22 are electrically connected to the positive and negative electrodes of the battery pack 38 respectively. One side of the "U"-shaped frame 21 is fixed with an electrode A29 and an electrode B30 respectively opposite to the two reversing electrodes 22. The other side of the two "U"-shaped frames 21 is fixed with an electrode A23 and an electrode B24 respectively opposite to the two reversing electrodes 22. The electrode B24 and the electrode B30 are electrically connected to the positive or negative electrode of the generator 14, and the electrode A23 and the electrode A29 are electrically connected to the negative or positive electrode of the generator 14.

[0040] A permanent magnet 27 is fixed to the inner wall of the slider 26 , an electromagnet 25 matching the permanent magnet 27 is fixed to the inner wall of the “U”-shaped frame 21 , and the electromagnet 25 is connected in parallel with the stator winding of the generator 14 .

[0041] When the generator 14 generates rotation in one direction, the stator winding of the generator 14 generates an electromotive force in one direction and applies it to the electromagnet 25, so that a magnetic force is generated between the electromagnet 25 and the permanent magnet 27, and the slider 26 is driven to move by the magnetic force, so that the commutation electrode 22 contacts the electrode 2 A29, the electrode 2 B30 or the electrode 1 A23 and the electrode 1 B24. When the movement direction of the generator 14 is opposite, the magnetic field generated by the electromagnet 25 is opposite in direction, so that the magnetic repulsion between the electromagnet 25 and the permanent magnet 27 is opposite, so that the slider 26 moves in the opposite direction, so that the commutation electrode 22 contacts the electrode 1 A23, the electrode 1 B24 or the electrode 2 A29, the electrode 2 B30. Since the electrode 2 B30 and the electrode 1 B24 are the same pole of the generator 14, and the electrode 1 A23 and the electrode 2 A29 are the other pole of the generator 14, their relative positions are misaligned, so that no matter which position the slider 26 is in, the electrode connection characteristics between the generator 14 and the battery pack 38 will not change.

[0042] This device utilizes the staggered electrode arrangement of electrode 1 A23, electrode 1 B24, electrode 2 A29, and electrode 2 B30, so that the positive-to-positive and negative-to-negative connection reliability of the generator 14 and the battery pack 38 can be achieved by the movement of the slider 26. In addition, by utilizing the different directions of the electromotive force of the stator winding at different turning periods of the generator 14, combined with electromagnetic conversion, the automatic drive control of the movement of the slider 26 is realized, achieving the purpose of self-induction and self-drive.

[0043] When the present embodiment is in use, the cantilever arm 1 can support the curtain wall assembly 2, and during the support, since the connecting frame 3 applies downward pressure to the cantilever 8, and the cantilever 8 rotates with the fixed support frame 17, the load of the cantilever 8 is provided by the supporting leaf spring 18, which is relatively flexible and has a certain buffering capacity. At the same time, the curtain wall glass 6 located on the front side plays a decorative role. At the same time, due to the light transmittance of the curtain wall glass 6, sunlight can penetrate the curtain wall glass 6 to irradiate the photovoltaic panel 7, and then be transmitted to the battery pack 38 for energy storage after photoelectric conversion. At the same time, the connecting frame 3 applies a load to the cantilever 8. The rotational torque generated by the cantilever 8 can be provided by the support of the supporting leaf spring 18 on the one hand, and on the other hand, it can be applied to the pull rope 10 by the rotational torque applied by the torsion spring 20 to the drum 12, and realized by the tension of the pull rope 10. When the connecting frame 3 swings, the cantilever 8 will rotate to a certain extent, so that the main shaft 11 and the main shaft 2 16 will rotate at a certain angle, thereby driving the generator 14 to rotate through the speed increase and range increase assembly 13, and the generator 14 will After the mechanical energy is converted into electrical energy, it is stored in the battery pack 38. In addition, when the generator 14 rotates in one direction, the stator winding of the generator 14 generates an electromotive force in one direction and applies it to the electromagnet 25, so that a magnetic force is generated between the electromagnet 25 and the permanent magnet 27. The slider 26 is driven to move by the magnetic force, so that the commutation electrode 22 contacts the electrode 2 A29, the electrode 2 B30, or the electrode 1 A23 and the electrode 1 B24. When the movement direction of the generator 14 is opposite, the direction of the magnetic field generated by the electromagnet 25 is opposite. On the contrary, the magnetic repulsion between the electromagnet 25 and the permanent magnet 27 is opposite, so that the slider 26 moves in the opposite direction, so that the commutation electrode 22 contacts the electrode 1 A23, the electrode 1 B24 or the electrode 2 A29, the electrode 2 B30. Since the electrode 2 B30 and the electrode 1 B24 are the same pole of the generator 14, and the electrode 1 A23 and the electrode 2 A29 are the other pole of the generator 14, their relative positions are misaligned, so that no matter what position the slider 26 is in, the electrode connection characteristics between the generator 14 and the battery pack 38 will not change.

[0044] Embodiment 2: An energy-saving curtain wall structure with energy recovery, such as Figure 6 , 7 As shown, in order to solve the problem of energy recovery efficiency; this embodiment makes the following improvements on the basis of embodiment 1: the speed increase and range increase component 13 includes an outer ring gear 32, a sun gear 34 and a gear 35, the outer ring gear 32 is fixed to the outer wall of the main shaft 11, the sun gear 34 is rotatably connected to the outer wall of the main shaft 11, and the outer ring gear 32 and the sun gear 34 are meshed with a plurality of planetary gears 33 on the opposite side, the side walls of the plurality of planetary gears 33 are rotatably connected to the same planetary gear carrier 31, the gear 35 is fixed to the outer wall of the main shaft 16, and the gear 35 is meshed with the outer wall of the planetary gear carrier 31.

[0045] A connecting ring 36 is fixed to one side of the sun gear 34, and the connecting ring 36 is coupled to the input shaft of the generator 14 through a synchronous assembly 37. In this embodiment, the specific type of the synchronous assembly 37 is not limited, and it can be a belt drive, a chain drive, a gear drive, etc., preferably a belt drive, which has good silent characteristics.

[0046] In this embodiment, when the main shaft 11 rotates, it drives the outer ring gear 32 to rotate, so that the planetary gear 33 drives the sun gear 34 to rotate under the assumption that the planetary gear 33 does not revolve, thereby driving the input shaft of the generator 14 to rotate. When the main shaft 16 rotates, it can drive the planetary gear carrier 31 to rotate through the gear 35, thereby driving the sun gear 34 to rotate under the condition that the outer ring gear 32 does not rotate, and the input shaft of the generator 14 is driven to rotate. Figure 6 As shown in the figure, when the cantilever 8 swings downward, the main shaft 11 and the main shaft 2 16 rotate counterclockwise, so that the sun gear 34 rotates clockwise regardless of whether it is driven by the main shaft 11 or the main shaft 2 16, and the rotation angle and speed of the sun gear 34 are the superposition of the two.

[0047] The device, by setting up a speed-increasing and range-increasing component 13, uses a dual-input drive form on the basis of using a "planetary gear set" to increase the speed, and combines the same direction of rotation of the main shaft 11 and the main shaft 2 16 when the cantilever 8 swings, so that the final rotation angle and speed of the sun gear 34 can be a superposition of the ratio of the rotation angle and speed of the main shaft 11 and the main shaft 2 16, thereby increasing the rotation range and speed of the generator 14 and increasing the energy recovery efficiency.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
