Description

Technical Field

[0001] This invention relates to the field of building structure technology, and more specifically to exterior wall glass for photovoltaic integrated buildings. Background Technology

[0002] As people's requirements for living or working environments increase, indoor spaces are generally equipped with fresh air systems, central air conditioning, and so on. These devices are powered by electricity, resulting in high electricity consumption, especially in office buildings where daily electricity consumption can reach as high as 1,000 kilowatt-hours. Therefore, utilizing outdoor solar energy to make up for some of the electricity consumption is a current development trend.

[0003] In existing technologies, photovoltaic panels are generally installed on the surface or inside of glass curtain walls to generate photovoltaic power. Furthermore, the photovoltaic panels are driven to deflect by means of motors and other technologies to maximize photovoltaic power generation. For example, Chinese invention patent CN114857712B discloses a building structure with light transmission and air purification functions. It generates electricity by setting up a power generation unit and using external solar and wind energy. The state switching structure of the power generation unit is a self-switching device, which includes an air compressor and an encoder at the end of the air compressor.

[0004] The aforementioned technologies have some shortcomings: the lifespan of photovoltaic panels differs significantly from that of motors, air compressors, encoders, etc. It's easy for the former to remain undamaged before reaching its lifespan limit, while the latter reaches its limit and fails, or vice versa. In such cases, the glass curtain wall and related building structures need to be disassembled and repaired. However, as is well known, glass curtain walls are generally constructed as an integrated structure, making disassembly and repair difficult. If the photovoltaic panels are damaged, then repairing them is the logical course of action. But if other structures are damaged, then disassembly and repair incurs additional costs, resulting in significant resource waste.

[0005] Based on this, the present invention proposes an exterior wall glass for photovoltaic integrated buildings. Summary of the Invention

[0006] To address the problems mentioned in the background above, the present invention provides photovoltaic integrated building exterior glass.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0008] Photovoltaic integrated building exterior glass, including a glass curtain wall, the glass curtain wall including a curtain wall frame, the internal space of the curtain wall frame is divided into an upper installation area and a lower installation area, tempered glass is installed at the opening of the upper installation area, and multiple sets of power generation units are arranged in an array along the length direction in the upper installation area. The power generation units are configured to switch between power generation state and standby state. A control mechanism is set in the lower installation area to control the state switching of the power generation units. When in power generation state, the power generation units are parallel to the tempered glass, and when in standby state, the power generation units are perpendicular to the tempered glass.

[0009] The power generation unit includes an outer frame that is rotatably mounted in the upper mounting area, with the pivot formed at the rotatable mounting point arranged vertically. A photovoltaic panel is installed inside the outer frame, which is made of transparent material. When the power generation unit is in power generation mode, a diffuser plate is installed on the side of the outer frame facing the interior.

[0010] Furthermore, the control mechanism includes a drive component, a supply component, a trigger component, and a connecting component disposed among the three. The supply component is used to provide power to the drive component through the connecting component. The trigger component is used to determine whether the power transmission route between the connecting component and the drive component is disconnected. The drive component is used to drive the power generation unit to switch states.

[0011] Furthermore, the supply components include a receiving assembly and a motor;

[0012] The motor includes a motor housing and a motor frame located in the lower mounting area. The two ends of the motor shaft located inside the motor housing are connected to the motor frame. The motor shaft is parallel to the length direction of the tempered glass. Notches are provided at the highest and lowest points of the motor housing.

[0013] An inner support is provided on the outside of the motor shaft. Several sets of photovoltaic panels are arranged in an array on the outer surface of the inner support along the circumference of the motor shaft. Several sets of coils are arranged in an array on the outside of the motor shaft along the circumference, and the coils correspond to the photovoltaic panels.

[0014] Magnets are installed at both the highest and lowest points of the inner cavity of the motor housing, and the coil is located between the two sets of magnets.

[0015] Furthermore, the photovoltaic panel 2 is provided with six sets, and the coil is provided with six sets. Two sets of coils located on the same shaft diameter of the motor shaft constitute a rotor, and two sets of photovoltaic panels 2 located on the same shaft diameter of the motor shaft constitute a power generation group. When the two sets of photovoltaic panels 2 in the power generation group are respectively facing the two sets of notches, there is an angle between the corresponding rotor and the magnet.

[0016] Furthermore, the receiving component includes a fixed housing disposed in the lower mounting area. The opening end of the fixed housing faces the outside and is provided with a transparent cover. The bottom of the fixed housing is composed of two sets of inclined surfaces, and the distance between the two sets of inclined surfaces decreases from the outside to the inside. A reflector is disposed inside the fixed housing. A light-transmitting opening is provided on the side of the fixed housing along the motor shaft axis. The reflector includes a mounting body. The upper and lower end faces of the mounting body are both arranged at an inclination, and the distance between them decreases along the motor shaft axis and in the direction close to the light-transmitting opening. A reflective sheet extends from the upper and lower end faces of the mounting body. The side of the reflective sheet facing the light-transmitting opening is set as an inclined surface. The distance between the inclined surface and the light-transmitting opening increases in the vertical direction and in the direction away from the mounting body. Several reflective sheets are arranged in an array along the extension direction of the mounting body.

[0017] A mounting cover is provided at the notch of the motor housing. A connection port is provided on the side of the mounting cover along the axial direction of the motor shaft. A reflector is provided between the connection port and the light-transmitting port. The reflector is used to guide the light from the light-transmitting port into the mounting cover.

[0018] The housing contains a second reflector, which includes a fixed body. The distance between the fixed body and the connection port decreases vertically and away from the notch. A second reflector sheet is provided on the side of the fixed body facing the notch. The side of the second reflector sheet facing the connection port is set as a slope three. The distance between the slope three and the connection port decreases vertically and away from the notch. Several second reflector sheets are arranged in an array along the extension direction of the fixed body.

[0019] Furthermore, the connecting components include a fixed bracket and a differential. The input shaft of the differential is connected to the motor shaft. One output half-shaft of the differential is connected to the drive component, and the other output half-shaft is equipped with a gear. A movable bracket is slidably mounted on the fixed bracket along the motor shaft axis. A spring is provided on the side of the movable bracket away from the trigger component. A gear three is provided on the movable bracket, and the gear three is parallel to the gear one. A gear two, coaxial with the gear three, is mounted on the fixed bracket. A speed increaser is provided at the output end of the gear two, and a flywheel is provided at the output end of the speed increaser.

[0020] Furthermore, the drive component includes a crank-slider assembly, which includes a crank connected to the differential output half-shaft, and a coil spring is provided between the differential and the crank-connected output half-shaft and the differential housing.

[0021] The crank has a protrusion at the end, and the crank slider assembly also includes a crossbeam. The crossbeam has vertically arranged sliding holes, and the protrusion slides within the sliding holes. The crossbeam and the outer frame form a sliding guide fit along the motor shaft axis. The crossbeam has a drive hole, which includes a horizontal section perpendicular to the glass curtain wall and an inclined section at the end of the horizontal section. The bottom of the outer frame has a protruding pin, which forms a sliding fit with the drive hole.

[0022] Furthermore, the triggering component includes a receiving component 2, a triggering component, and a reflector 2 disposed between the two. The receiving component 2 and the reflector 2 cooperate to guide external light to illuminate the triggering component.

[0023] Furthermore, the triggering component includes a closed cover, the opening of the closed cover and the reflector are connected, a hollow sphere is provided inside the closed cover, and a thermal expansion medium is provided inside the hollow sphere;

[0024] The side of the enclosed cover is provided with a pump casing and the pump casing is connected to the hollow ball. A piston is installed inside the pump casing, and a piston rod extends from the end face of the piston. The end of the piston rod contacts the movable support.

[0025] Compared with the prior art, the beneficial effects of this invention are as follows:

[0026] In this solution, after sunrise in the morning, the control mechanism drives the power generation unit to power generation, with the power generation unit parallel to the tempered glass to maximize power generation. After sunset in the evening, the control mechanism drives the power generation unit to standby mode, with the power generation unit perpendicular to the tempered glass, so as not to affect the light shining into the room in the evening or at night, and not to affect the user's view of the outdoor night view, etc.

[0027] Furthermore, when generating electricity or in standby mode, some outdoor light will pass through the outer frame and the diffuser plate before entering the room. The presence of the diffuser plate allows the light to shine evenly into the room. On the one hand, it makes the room bright during the day, and on the other hand, it will not create a projection of the outer frame inside the room, thus affecting the living experience.

[0028] Based on the above, one of the core aspects of this invention is:

[0029] I. In this solution, the operation of the motor is achieved by the cooperation of photovoltaic panel two and coil. The significance is that photovoltaic panel two and photovoltaic panel one have the same structure. If one of them reaches the end of its service life and is damaged, it means that the other is also about to reach the end of its service life. Therefore, no matter which one needs to be repaired, both can be repaired at the same time, without causing waste of resources.

[0030] Second, apart from the motor, the rest of this design is a purely mechanical structure with a very long service life.

[0031] Thirdly, this solution utilizes the cooperation of a thermal expansion medium and a differential to control the power connection between the differential and the drive components, thereby controlling the state switching of the power generation unit. The advantage of this temperature-triggered method is that in summer, when the temperature is high, the power generation unit can switch to power generation mode shortly after sunrise and switch back to standby mode as the sun is about to set, maximizing the power generation time. In winter, when the temperature is low, power generation takes longer after sunrise and stops long before sunset. In other words, power generation is concentrated during the midday period when sunlight is strong. The significance of this is that photovoltaic power generation is intended to provide power to indoor equipment, reducing power consumption. In winter, the most power-consuming indoor function is air conditioning and heating. Since sunlight is generated and then supplied to the air conditioner, there will inevitably be losses in between. Therefore, allowing sunlight to directly shine into the room eliminates these losses. Moreover, the photovoltaic panels in the power generation unit are perpendicular to the tempered glass of the glass curtain wall, so it does not affect the sunlight shining into the room.

[0048] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0049] In this plan, exterior glass refers to glass curtain walls.

[0050] Reference Figures 1-14The photovoltaic integrated building exterior glass includes a glass curtain wall 100, which includes a curtain wall frame. The interior space of the curtain wall frame is divided into an upper installation area and a lower installation area. Tempered glass is installed at the opening of the upper installation area, and multiple sets of power generation units 101 are installed inside for photovoltaic power generation. The power generation units 101 are configured to switch between power generation and standby states. A control mechanism 200 is installed in the lower installation area to control the state switching of the power generation units 101. Specifically, after sunrise in the morning, the control mechanism 200 drives the power generation units 101 to power generation state, with the power generation units 101 parallel to the tempered glass to maximize power generation. After sunset in the evening, the control mechanism 200 drives the power generation units 101 to standby state, with the power generation units 101 perpendicular to the tempered glass to avoid affecting the sunlight shining into the room in the evening or at night.

[0051] Reference Figure 2 and Figure 3 The array direction of the multiple power generation units 101 is parallel to the length direction of the tempered glass.

[0052] Furthermore, refer to Figure 4 The power generation unit 101 includes an outer frame 1011 rotatably mounted in the upper mounting area, with the pivot formed at the rotatable mounting point arranged vertically. A photovoltaic panel 1012 is disposed inside the outer frame 1011. The outer frame 1011 is made of transparent material. When the power generation unit 101 is in the power generation state, a diffuser is disposed on the side of the outer frame 1011 facing the interior. The significance of this is that even in the daytime power generation state, some light can still pass through the outer frame 1011 and the diffuser to enter the interior, making the interior bright.

[0053] Reference Figure 5 The control mechanism 200 includes a connecting member 300, a driving member 400, a supply member 500, and a triggering member 600, wherein:

[0054] The connecting member 300 is disposed between the driving member 400, the supply member 500, and the triggering member 600;

[0055] The supply component 500 is used to provide power to the drive component 400 via the connecting component 300;

[0056] The triggering component 600 is used to determine whether the power transmission path between the connecting component 300 and the driving component 400 is disconnected;

[0057] The drive component 400 is used to drive the power generation unit 101 to switch states.

[0058] I. Supply of 500 components:

[0059] Reference Figures 6-9The supply component 500 includes a receiving component and a motor.

[0060] Reference Figure 8 and Figure 9 The motor includes a motor housing 507 and a motor frame 508 located in the lower mounting area. A motor shaft 509 is coaxially mounted inside the motor housing 507. Both ends of the motor shaft 509 extend out of the motor housing 507 and are connected to the motor frame 508. The motor shaft 509 is parallel to the length direction of the tempered glass. Notches are provided at the highest and lowest points of the motor housing 507.

[0061] An inner support 510 is provided on the outside of the motor shaft 509, and several sets of photovoltaic panels 511 are arrayed on the outer surface of the inner support 510 along the circumferential direction of the motor shaft 509.

[0062] Several sets of coils 513 are arranged in an array along the circumferential direction on the outside of the motor shaft 509. The coils 513 correspond to the photovoltaic panel 511. For example, in this scheme, there are six sets of photovoltaic panel 511 and six sets of coils 513. Two sets of coils 513 located on the same shaft diameter of the motor shaft 509 constitute a rotor, and two sets of photovoltaic panels 511 located on the same shaft diameter of the motor shaft 509 constitute a power generation unit.

[0063] Magnets 512 are provided at the highest and lowest points of the inner cavity of the motor housing 507, and the coil 513 is located between the two sets of magnets 512. When the two sets of photovoltaic panels 511 in the power generation unit are respectively facing the two sets of notches, there is an angle between the rotor and the magnets 512.

[0064] The motor operates as follows: outdoor light is drawn through the notch by the receiving component and directed towards the corresponding power generation unit. The photovoltaic power generated by the power generation unit provides electricity to the corresponding rotor. With the cooperation of the rotor and the magnet 512, the rotor can rotate, which in turn causes the motor shaft 509, the inner support 510 and the photovoltaic panel 511 to rotate together. When the power generation unit rotates away from the notch position, the rotation of the corresponding rotor reaches its maximum angle and stops. At the same time, the next power generation unit faces the notch and the next rotor continues to rotate. This process is repeated to realize the operation of the motor and make the motor shaft 509 rotate continuously.

[0065] In the above process, the unique design of the motor is that the photovoltaic panel 511 and the coil 513 work together to realize the operation of the motor. The significance is that the photovoltaic panel 511 and the photovoltaic panel 1012 have the same structure. If one of them reaches the end of its service life and is damaged, it means that the other is also about to reach the end of its service life. Therefore, no matter which one needs to be repaired, both can be repaired at the same time, without causing waste of resources.

[0066] Conversely, with common motor technologies, brushed motors require regular replacement due to the presence of carbon brushes, resulting in a relatively short lifespan. Brushless motors contain Hall effect sensors, which are prone to aging over time. Furthermore, the motor's location near the outdoors and the high internal temperature of the mounting area further affect the lifespan of the Hall effect sensors. Consequently, neither brushed nor brushless motors can match the lifespan of photovoltaic panels.

[0067] Reference Figure 6 and Figure 7 The receiving component includes a fixed housing 501 disposed in the lower mounting area. The opening end of the fixed housing 501 faces the outside and is provided with a transparent cover 502, for example, made of glass. The bottom of the cavity of the fixed housing 501 is composed of two sets of inclined surfaces, and the distance between the two sets of inclined surfaces decreases from the outside to the inside.

[0068] The fixed cover 501 has a reflector 503 inside and a light-transmitting opening on the side along the axial direction of the motor shaft 509. The reflector 503 includes a mounting body. The upper and lower end faces of the mounting body are both inclined and the distance between them decreases along the axial direction of the motor shaft 509 and towards the light-transmitting opening. The upper and lower end faces of the mounting body each have a reflective sheet 1 extending from them. The side of the reflective sheet 1 facing the light-transmitting opening is set as a slope 2. The distance between the slope 2 and the light-transmitting opening increases vertically and away from the mounting body. Several reflective sheets 1 are arranged in an array along the extension direction of the mounting body. After outdoor light enters the fixed cover 501, it is reflected by the bottom of the cavity of the fixed cover 501 (the bottom of the cavity is set as a mirror surface to reflect light) onto the reflective sheet 1, and then reflected by the reflective sheet 1 to the light-transmitting opening.

[0069] A mounting cover 505 is provided at the notch of the motor housing 507. The mounting cover 505 has a connection port on its side along the axial direction of the motor shaft 509. A reflector 504 is provided between the connection port and the light-transmitting port. The reflector 504 is used to guide the light from the light-transmitting port into the connection port and then into the mounting cover 505. The reflector 504 is a technology that can be implemented in the prior art, such as periscope technology, and will not be described in detail.

[0070] A second reflector 506 is provided inside the mounting housing 505. The second reflector 506 includes a fixed body. The distance between the fixed body and the connection port decreases vertically and away from the notch. A second reflector sheet is provided on the side of the fixed body facing the notch. The side of the second reflector sheet facing the connection port is set as a slope three. The distance between the slope three and the connection port decreases vertically and away from the notch. Several second reflector sheets are arranged in an array along the extension direction of the fixed body. The light guided into the mounting housing 505 by the first reflector 504 is divided and reflected by several second reflector sheets, passes through the notch and enters the motor housing 507.

[0071] In a preferred embodiment, although the receiving component one can guide light into the motor housing 507 to make the motor run, the torque at the output end of the motor shaft 509 is relatively small. Therefore, referring to... Figure 8 A reducer 514 can be installed at the output end of the motor shaft 509 to increase the output torque.

[0072] II. Connecting component 300:

[0073] Reference Figures 12-14 The connecting component 300 includes a fixed bracket 301 and a differential 302. The input shaft of the differential 302 is connected to the output end of the reducer 514. One output half shaft of the differential 302 is connected to the drive component 400, and the other output half shaft is provided with a gear 303.

[0074] A movable bracket 307 is slidably mounted on the fixed bracket 301 along the motor shaft 509. A spring 308 is provided on the side of the movable bracket 307 away from the triggering member 600. A gear 309 is provided on the movable bracket 307. The gear 309 is parallel to the gear 1 303. A gear 2 304 is mounted on the fixed bracket 301 and is coaxial with the gear 1 303. The parameters of the gear 2 304 are the same as those of the gear 1 303.

[0075] The output end of gear 2 304 is equipped with a speed increaser 305, and the output end of speed increaser 305 is equipped with a flywheel 306; the purpose of setting speed increaser 305 is to make the rotation resistance of flywheel 306 greater.

[0076] In the initial state, gear 309 and gear 1 303 are not meshed. At this time, since the drive component 400 requires a certain force to run, based on the principle of differential 302, all the power of the motor is transmitted to gear 1 303, and gear 1 303 idles.

[0077] When the triggering component 600 is triggered, it drives the movable bracket 307 to move, causing gear 309 to mesh with gear 1 303. At gear 1 303, there is a load on the flywheel 306. This load is greater than the running resistance of the driving component 400. In other words, at this time, based on the principle of differential 302, all the power of the motor is transmitted to the driving component 400, causing the generator unit 101 to switch to the generator state. After the state switch is completed, the generator unit 101 can no longer deflect, and the driving component 400 can no longer move. After that, all the power of the motor is transmitted to gear 1 303, causing the flywheel 306 to idle.

[0078] III. Driving component 400:

[0079] Reference Figure 13The drive component 400 includes a crank-slider assembly 401, which includes a crank connected to the output half-shaft of the differential 302. In addition, a coil spring 404 is provided between the output half-shaft of the differential 302 and the crank and the housing of the differential 302.

[0080] The crank has a protrusion at the end, and the crank-slider assembly 401 also includes a crossbeam 402. The crossbeam 402 has a vertically arranged sliding hole, and the protrusion slides in the sliding hole. The crossbeam 402 and the outer frame 1011 form a sliding guide fit along the motor shaft 509 axis. When the output half shaft of the differential 302 rotates with the crank, the crossbeam 402 can move through the fit between the protrusion and the sliding hole.

[0081] A drive hole 403 is provided on the crossbeam 402. The drive hole 403 includes a horizontal section perpendicular to the glass curtain wall 100 and an inclined section provided at the end of the horizontal section. (Refer to...) Figure 4 The bottom of the outer frame 1011 is provided with a protruding pin 1013, which forms a sliding fit with the drive hole 403. When the cross frame 402 moves, the outer frame 1011 can be deflected through the fit between the protruding pin 1013 and the drive hole 403, so that the power generation unit 101 can switch states. It should be noted that the reason for setting the inclined section is to ensure that when the power generation unit 101 is in the power generation state, the photovoltaic panel 1012 is parallel to the tempered glass of the glass curtain wall 100, and when it is in the standby state, it is perpendicular to the tempered glass of the glass curtain wall 100.

[0082] IV. Triggering component 600:

[0083] Reference Figure 5 , Figure 10 and Figure 11 The triggering component 600 includes a receiving component 2 601, a triggering component 603, and a reflector 2 602 disposed between the two. The structure of the receiving component 2 601 is the same as that of the receiving component 1, and the structure of the reflector 2 602 is the same as that of the reflector 1 504. The receiving component 2 601 and the reflector 2 602 cooperate to guide external light toward the triggering component 603, which will not be described in detail.

[0084] Reference Figure 11 The triggering component 603 includes a closed cover 6031, the opening of the closed cover 6031 is connected to the reflector 602, and a hollow sphere 6035 is disposed inside the closed cover 6031, and a thermal expansion medium is disposed inside the hollow sphere 6035.

[0085] A pump housing 6032 is provided on the side of the enclosed cover 6031 and is connected to the hollow ball 6035. A piston 6033 is installed inside the pump housing 6032. A piston rod 6034 extends from the end face of the piston 6033 and the end of the piston rod 6034 contacts the movable support 307. When the hollow ball 6035 is exposed to light, its temperature rises, causing the thermal expansion medium to expand thermally, which in turn pushes the piston 6033 to move. The piston 6033 pushes the movable support 307 to move through the piston rod 6034.

[0086] Working principle of the invention:

[0087] In the morning, the light shines into the motor through the cooperation of receiving component one, reflector one 504, and reflector two 506, causing the motor to run and the motor shaft 509 to rotate. Since gear three 309 is not engaged with gear one 303 at this time, the output half shaft of differential 302 corresponding to gear one 303 rotates with gear one 303, while the output half shaft corresponding to drive component 400 does not rotate.

[0088] At the same time, the morning light shines into the enclosure 6031 through the cooperation of receiving component 2 601 and reflector 2 602;

[0089] After a preset time, the temperature of the hollow ball 6035 rises, the thermal expansion medium expands, and then pushes the piston 6033 to move. The piston 6033 pushes the movable bracket 307 to move through the piston rod 6034. The movement of the movable bracket 307 enables the gear 309 to mesh with the gear 1 303 and the gear 2 304 at the same time. At this time, since the load on the flywheel 306 is relatively large, all the power of the motor is transmitted to the drive component 400, and the output half shaft corresponding to the gear 1 303 stops rotating.

[0090] When the drive component 400 is running, the crank-slider assembly 401 drives the crossbeam 402 to move. Then, through the cooperation of the protruding pin 1013 and the drive hole 403, the power generation unit 101 is switched to the power generation state. After the state is switched, the crossbeam 402 can no longer move. At this time, the power of the motor is transferred to the flywheel 306, and the power generation unit 101 maintains the power generation state to generate photovoltaic power.

[0091] As evening falls and the light gradually weakens, the temperature of the hollow sphere 6035 decreases. The spring 308 releases its elastic force, causing the movable bracket 307 to move in the opposite direction. Gear 309 disengages from gears 1 303 and 2 304, and the thermal expansion medium retreats back into the hollow sphere 6035. At this time, all the power of the motor is transmitted to the output half-shaft corresponding to gear 1 303. Simultaneously, the coil spring 404 releases its elastic force, causing the crank-slider assembly 401 to move in the opposite direction, which in turn causes the crossbeam 402 to move in the opposite direction, ultimately switching the power generation unit 101 to standby mode.

[0092] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
