Description

Technical Field

[0001] The present invention relates to the technical field of green buildings, and particularly to a power generation driving device and method based on interior casement windows and interior sunshade curtains in a building. Background Art

[0002] A green building refers to a high-quality building that can maximize the harmonious coexistence between humans and nature by saving resources, protecting the environment, reducing pollution, and providing healthy, applicable, and efficient usable spaces for people throughout its entire life cycle; the utilization of wind energy is a process of converting the kinetic energy generated by air flow into mechanical energy or other forms of energy, and in green buildings, wind energy is mostly utilized by adjusting the temperature, humidity, etc. inside the building.

[0003] When the partial sunshade curtain on the inner side of the interior casement window in a building is in a state where both side windows are open, under the action of wind on both sides, it will continuously move away from and approach the interior casement window glass. When it approaches the interior casement window glass, it will impact the interior casement window glass under the influence of gravitational potential energy, generating noise. At the same time, over a long period, it will cause damage to the relevant structures during the impact process; also, in the green building system, if one wants to collect the kinetic energy and mechanical energy generated during the swinging process of the sunshade curtain, the technical problem lies in that if one wants to collect its kinetic energy and mechanical energy, the sunshade curtain needs to be fixed so that it can perform energy conversion in a stable state; if the sunshade curtain is not fixed, it will be in a chaotic state under the action of wind, and it is difficult to convert energy. Therefore, a structure is needed that can satisfy the swinging of the sunshade curtain and can serve as the hardware basis for energy conversion during the swinging process of the sunshade curtain.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] The present invention provides a power generation drive device based on an inward-opening window and an internal sunshade curtain in a building, including a sunshade curtain. A reel is arranged at the top of the sunshade curtain, and a fixing device is arranged at the bottom. A transverse stiffening shaft is arranged in the middle of the sunshade curtain. The transverse stiffening shaft can be used to balance when the two sides of the sunshade curtain are affected by unbalanced wind forces, transmit the deformation area at the edge of the sunshade curtain to the middle, so that the relative displacement between the connecting line of the generator rotating shaft and the power generation device is maximized, convert mechanical energy into electrical energy. At the same time, the transverse stiffening shaft can limit the movement area of the end of the connecting line of the generator rotating shaft, so that the end of the connecting line of the generator rotating shaft is located at the center of the sunshade curtain, thereby increasing the relative displacement amount between the connecting line of the generator rotating shaft and the power generation device. A one-way flexible guide rail is arranged along the length direction of the sunshade curtain between the transverse stiffening shaft and the fixing device. A power generation device is arranged on the side of the reel close to the wall.

[0021] The present invention provides a power generation drive method based on an inward-opening window and an internal sunshade curtain in a building. When the sunshade curtain is opened, the fixing device at the bottom of the sunshade curtain is fixed to the wall, the magnetic spring assembly is electrified, and one end of the connecting line of the generator rotating shaft approaches the transverse stiffening shaft in the one-way flexible guide rail.

Detailed implementation manners

[0031] The following further elaborates on the present invention in detail with specific embodiments, which is an explanation rather than a limitation of the present invention.

[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of the present invention are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0034] The present invention provides a power generation drive device based on a casement window and an internal sunshade curtain in a building, as Figure 1 shown, which includes a sunshade curtain 73. A scroll 71 is provided at the top of the sunshade curtain 73, and a fixing device 72 is provided at the bottom. A transverse stiffening shaft 74 is provided in the middle of the sunshade curtain 73. A one-way flexible guide rail 75 is provided along the length direction of the sunshade curtain 73 between the transverse stiffening shaft 74 and the fixing device 72, and the transverse stiffening shaft 74 is perpendicular to the one-way flexible guide rail 75. A power generation device 7 is provided at intervals on the side of the scroll 71 close to the wall. The power generation device 7 is connected with a generator shaft connecting line 76. One end of the generator shaft connecting line 76 is slidably arranged on the curved side of the one-way flexible guide rail 75, and a magnetic spring assembly is arranged between the end of the generator shaft connecting line 76 and the fixing device 72. It should be noted that the fixing device 72 adopts a lightweight metal fixing box body, as Figure 2 shown. A window is provided on the wall. The window includes an upper window frame 91, a lower window frame 92 and side window frames 93. Those skilled in the art can pre-set an electromagnetic locking device on the lower window frame 92, and the bottom of the sunshade curtain can be fixed through the electromagnetic locking device to prevent it from swinging with the wind and knocking on the window surface. When it is affected by wind force, the scroll 71 arranged on the upper window frame 91 is loosened, and at this time the sunshade window is bent into an arc structure. At the same time, those skilled in the art can set circular rollers 721 at both ends of the fixing device 72. The circular rollers 721 adopt lightweight rubber rollers, which have the characteristics of quietness and light weight. During the process of retracting and lowering the sunshade curtain 73, it directly abuts against the inner side of the side window frame 93 close to the interior, avoiding friction and impact between the fixing device 72 and the side window frame 93, thereby prolonging the service life. At the same time, it can prevent the risk of breaking the glass when the fixing device 72 swings irregularly when the two sides of the sunshade curtain 73 are affected by unbalanced wind forces.

[0035] Preferably, a plurality of circular rollers 60 fixedly connected in parallel are provided at the end of the generator shaft connecting wire 76 to increase the friction during its sliding between the first guide rail backing plate 4 and the second guide rail backing plate 5, prevent wear during long-term use, and extend its service life. Preferably, the magnetic spring assembly includes a spring disposed within the fixing device 72 and at the bottom of the one-way flexible guide rail 75, and a magnet disposed at the end of the generator shaft connecting wire 76. The magnet is located on the circular roller 60 at the last stage. The spring is connected to a power source, and the power source is disposed within the fixing device 72. It should be noted that when the power source energizes the spring, an electromagnetic effect is generated. At this time, positive and negative poles appear at both ends of the spring. Based on the principle of like poles repelling and opposite poles attracting, the position of the circular roller 60 on the one-way flexible guide rail 75 can be controlled. It should be noted that the magnetic spring assembly is a prior art, and its structure and principle are not described in this application. It should be further noted that the opening and closing of the electromagnetic locking device can be synchronized with the startup of the power source of the magnetic spring assembly. That is, when the electromagnetic locking device is opened, the power source of the magnetic spring assembly is started, causing the magnet to move away from and close to the transverse stiffening shaft 74. When the electromagnetic locking device is closed, the power source of the magnetic spring assembly is also closed. At this time, the magnet is affected by gravity and falls and approaches the fixing device 72.

[0036] Preferably, as Figure 3 shown, the one-way flexible guide rail 75 includes a plurality of guide rail bodies 1 connected in series step by step from end to end. One end of the guide rail body 1 is provided with a guide rail connector 2, and the other end is provided with a guide rail connection groove 3. The guide rail connector 2 and the guide rail connection groove 3 are detachably and rotatably connected by a pin; both sides of the guide rail body 1 of the guide rail connector 2 and the guide rail connection groove 3 are provided with arc-shaped end faces 10, and a guide rail turning limiting piece 54 is provided at the bottom of the guide rail connection groove 3 along the length direction of the guide rail body 1. The guide rail turning limiting piece 54 is adapted to the arc-shaped end face 10. The guide rail turning limiting piece 54 and the arc-shaped end face 10 enable only one-way rotation between adjacent guide rail bodies 1, and the one-way flexible guide rail 75 formed thereby can also only rotate in one direction; a first guide rail backing plate 4 and a second guide rail backing plate 5 are arranged vertically and spaced apart in the length direction of the plurality of guide rail bodies 1. The second guide rail backing plate 5 and the guide rail turning limiting piece 54 are located on the same horizontal plane. The first guide rail backing plate 4 and the second guide rail backing plate 5 are used to reserve a sliding track for one end of the generator shaft connecting wire 76. Specifically, an adhesive sheet is provided on one side of the guide rail body 1 close to the sunshade 73 for adhering to the sunshade 73, specifically on the bottom surface of the guide rail body 1. This embodiment is applicable to the case where the sunshade 73 has a small size. When the size of the sunshade 73 is small, its swing inertia generated by the wind force is small, and a single one-way flexible guide rail 75 can ensure its structural strength and basic energy conversion hardware conditions.

[0037] Preferably, asFigure 4 and Figure 7 As shown, there are two unidirectional flexible guide rails 75 arranged in parallel. At the bottom of the side wall of the guide rail body 1, there is a second guide rail backing plate 5 at the same horizontal level as the guide rail turning limiting piece 54. On one side of the second guide rail backing plate 5 close to the chain of the adjacent guide rail body, a tenon structure 11 and a mortise structure 12 are arranged at intervals. Between the second guide rail backing plates 5 of two adjacent guide rail bodies 1 in the parallel guide rail body chain, the tenon structure 11 and the mortise structure 12 are arranged staggeredly. Here, it should be noted that if two unidirectional flexible guide rails 75 are adopted, two guide rail bodies 1 with only different second guide rail backing plates 5 need to be set respectively, which are respectively used on the two unidirectional flexible guide rails 75 to form mutual clamping. If they are connected in a staggered manner, it will affect the balance and stability during the bending process; this embodiment is applicable to the case where the sunshade curtain 73 is of a large size. When the sunshade curtain 73 is of a large size, the swinging inertia generated by the action of wind force is large, so two unidirectional flexible guide rails 75 are required to ensure its structural strength and basic energy conversion hardware conditions; at the same time, the two unidirectional flexible guide rails 75 provide a more stable sliding space and structural strength for the motor shaft connecting line 76, and at the same time can make the swinging of the sunshade curtain 73 more stable.

[0038] Preferably, a retaining piece is arranged at the edge of the first guide rail backing plate 4 and / or the second guide rail backing plate 5; at one end of the first guide rail backing plate 4, there is a guide rail circular rubber section 42, and at the other end, there is a guide rail arc backing plate 41. The guide rail circular rubber section 42 and the guide rail arc backing plate 41 are structurally adapted; the guide rail arc backing plate 41 only needs to wrap a part of the outer wall of the guide rail circular rubber section 42. Wrapping too large an area will cause structural interference in the proximity of adjacent guide rail bodies 1. In this embodiment, the guide rail circular rubber section 42 and the guide rail arc backing plate 41 can make the connection between adjacent guide rail bodies 1 have no gap and prevent the end of the generator shaft connecting line 76 from slipping off.

[0039] Preferably, at one end of the second guide rail backing plate 5, there is a torsion spring reel 51, and a limiting piece 52 is arranged along the extension direction of the second guide rail backing plate 5 for the torsion spring reel 51. At the other end, there is a limiting post 53 structurally adapted to the limiting piece 52, which is used to strengthen the reset function of the unidirectional flexible guide rail 75, so that after the unidirectional flexible guide rail 75 is bent, there is a tendency to return to its original state, and cooperate with the wind force to make the unidirectional flexible guide rail 75 form a frequency of bending and straightening conversion, thereby improving the power conversion efficiency of the power generation device 7.

[0040] Preferably, the guide rail connector 2 of the first guide rail body 1 among the multiple guide rail bodies 1 connected in series step by step from head to tail is hinged to a fixed point, and the guide rail connection groove 3 of the guide rail body 1 at the tail of the multiple guide rail bodies 1 connected in series step by step from head to tail is hinged to another fixed point; the fixed point is a fixing device 72, and the other fixed point is a transverse stiffening shaft 74; it should be noted that the guide rail connector 2 is provided with a first pin hole 21 in a penetrating manner, and arc-shaped end faces 10 on both sides of the guide rail connection groove 3 are provided with second pin holes 31 adapted to the position of the first pin hole 21, and they are detachably hinged through the cooperation of the first pin hole 21 and the second pin hole 31 with a pin, with strong versatility and applicability; the guide rail body 1 is made of polyethylene material, which has good chemical stability, is light in weight, has a small gravitational effect on the sunshade curtain, has high structural strength, and is strong and durable.

[0041] Preferably, as Figure 5 and Figure 6 shown, one-way rotary hinges 8 are provided on both side edges of the sunshade curtain 73. The one-way rotary hinge 8 includes hinge bodies 81 connected in series step by step from head to tail. One end of the hinge body 81 is provided with a hinge connection section 82, and the other end is provided with a hinge connection groove 83 adapted to the structure of the hinge connection section 82. A hinge turning limiting piece 84 is provided at the bottom of the hinge connection groove 83, and hinge arc-shaped end faces 80 are provided on the hinge bodies 81 on both sides of the hinge connection section 82 and the hinge connection groove 83. And a hinge turning limiting piece 84 is provided along the length direction of the hinge body 81 at the bottom of the hinge connection groove 83, and the hinge turning limiting piece 84 is adapted to the hinge arc-shaped end face 80; hinge first clamping plates 85 and hinge second clamping plates 86 are alternately arranged on the side wall of the hinge body 81 close to the sunshade curtain 73, and a flexible gasket 87 is provided on the side of the hinge body 81 close to the wall; it should be noted that the one-way rotary hinge 8 and the one-way flexible guide rail 75 are similar in structure. Its function is to prevent the two sides of the sunshade curtain 73 from making the sunshade curtain 73 have only a movement tendency away from the interior casement window of the building when affected by unbalanced wind forces, and at the same time prevent its side edges from bending towards the glass side and hitting the glass. Specifically, the hinge first clamping plates 85 and the hinge second clamping plates 86 are fixed to the side edges of the sunshade curtain 73 by rivets.

[0042] The reel 71 can adopt a low-damping reel structure inside, which is to make the sunshade curtain 73 easily have a movement tendency away from the interior casement window of the building when affected by wind forces.

[0043] The present invention provides a power generation driving method based on an interior window and an interior sunshade curtain of a building, including the following steps:

[0044] As Figure 8As shown, when the sunshade curtain 73 is opened, the fixing device 72 at the bottom of the sunshade curtain 73 is fixed to the lower window frame 92. The magnetic spring assembly is powered on, and one end of the generator rotating shaft connecting line 76 approaches the transverse stiffening shaft 74 within the one-way flexible guide 75. At this time, the sunshade curtain 73 is blown away from the wall by the wind, and one end of the motor rotating shaft connecting line 76 is stressed and pulls the internal power generation rotating shaft of the power generation device 7 to generate electric energy;

[0045] When the sunshade curtain 73 is retracted, the fixing device 72 at the bottom of the sunshade curtain 73 is not fixed to the lower window frame 92. The magnetic spring assembly is powered off, and one end of the generator rotating shaft connecting line 76 approaches the fixing device 72 within the one-way flexible guide 75. At this time, the motor rotating shaft connecting line 76 is wound into the reel 71 along with the one-way flexible guide 75.

[0046] It should be further noted that the opening and closing of the electromagnetic locking device can be synchronized with the power startup of the magnetic spring assembly. That is, when the electromagnetic locking device is opened, the power of the magnetic spring assembly is started, causing the magnet to move away from and approach the transverse stiffening shaft 74. When the electromagnetic locking device is closed, the power of the magnetic spring assembly is also turned off. At this time, the magnet is affected by gravity and falls and approaches the fixing device 72.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
