[0003] Currently, Chinese patent CN219998235U discloses a double-sided coated photovoltaic glass, including an outer frame. A limiting mechanism is fixedly installed inside one end of the outer frame. The limiting mechanism includes a limiting groove, which is located at the top of one end of the outer frame. An inner frame is movably installed inside the outer frame via a torsion spring shaft. By setting the inner frame inside the outer frame and installing the photovoltaic glass body inside the inner frame, a locking plate is moved to both sides, and one end of the locking plate separates from the fixing block. The inner frame rotates under the torque of the torsion spring shaft. By adjusting the limiting mechanism, the photovoltaic glass body can be easily removed from the bottom side of the outer and inner frames, facilitating the side-by-side installation of more photovoltaic glasses without affecting the replacement and maintenance of the photovoltaic glass body. During installation, the photovoltaic glass body is inserted into the placement groove through the insertion port, and the inner frame and photovoltaic glass body are pushed. The locking plate limits the fixing block, which can fix the inner frame and photovoltaic glass body inside the outer frame, making it convenient to use.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-6 This embodiment provides a photovoltaic insulating glass, including an outer frame 100. The inner cavity of the outer frame 100 is connected to a U-shaped frame 101 via a rotating connection assembly. A photovoltaic glass body 102 is inserted into the inner cavity of the U-shaped frame 101. The opening of the U-shaped frame 101 is connected to a limiting plate 103 for preventing the photovoltaic glass from sliding out via a detachable connector. A limiting member is provided on one side bottom of the outer frame 100 for fixing the limiting plate 103 to prevent it from disengaging from the inner cavity of the outer frame 100.

[0035] The limiting component includes a locking plate 200 fixedly installed on one side of the limiting plate 103. A locking groove 107 is provided on the bottom side of one side of the outer frame 100 and at a corresponding position on the locking plate 200. A through hole 211 is provided along the length of one side of the locking plate 200. A wedge block 204 is slidably connected to the middle of the through hole 211. Both sides of the inclined surface of the wedge block 204 contact the plug-in plate 201. Cavities 110 are provided inside the limiting plate 103 and on both sides of the locking groove 107. A downwardly movable wedge block 204 is provided at the bottom of the locking plate 200 to hold the two sets of plug-in plates 201 together. A movable component is inserted into the corresponding side cavity 110 through the through hole 211. The two cavities 110 are respectively provided with fixing members for fixing the end of the plug plate 201. By setting the limiting member, the wedge block 204 moves downward, pushing the two plug plates 201 to move to both sides and insert into the corresponding side cavity 110, thereby fixing the limiting plate 103 and preventing the photovoltaic glass body 102 from shifting or even falling off due to the limiting plate 103 loosening or falling off, thus enhancing the stability of the structure during long-term use.

[0036] The movable component includes a circular hole 205 located at the bottom of the card plate 200 and connected to the through hole 211. A lead screw 203 is rotatably connected to the inner cavity of the circular hole 205. The end of the lead screw 203 is threaded upward through a wedge block 204. The end of the lead screw 203 is connected to the top inner wall of the through hole 211 via a rotating connector. A limiting ring 206 is fixedly sleeved on the head of the lead screw 203 and rotatably connected to the inner wall of the circular hole 205. Through the movable component, the lead screw 203 can precisely control the wedge shape by engaging with the threaded engagement of the wedge block 204 when rotating. The up-and-down movement of block 204 within through hole 211 not only provides high precision and stability, ensuring that wedge block 204 can accurately push the two sets of plug-in plates 201 out of through hole 211 and insert them into the corresponding cavity 110, achieving a reliable connection, but also ensures that the limiting ring 206 at the head of lead screw 203 is rotatably connected to the inner wall of circular hole 205, and the end of lead screw 203 is connected to the top inner wall of through hole 211 through a rotating connector, ensuring the stability of lead screw 203 during rotation and preventing lead screw 203 from shaking or deviating, thereby ensuring the normal operation of the entire moving assembly.

[0037] Among them, the photovoltaic glass body 102 is a well-known technical means in the art. For its specific structure and principle, please refer to Chinese Patent Publication No. CN219998235U, which discloses a photovoltaic glass body in double-sided coated photovoltaic glass. The rest will not be described in detail here.

[0038] The rotating connector includes a connecting post 202 fixedly installed at the end of the lead screw 203. The connecting post 202 is rotatably inserted into the top inner wall of the through hole 211. By setting the rotating connector, the connecting post 202 at the end of the lead screw 203 is rotatably inserted into the top inner wall of the through hole 211, providing a stable rotation fulcrum for the lead screw 203, enabling the lead screw 203 to rotate smoothly, and further improving the reliability and stability of the moving component.

[0039] The detachable connector includes countersunk bolts 105 that are respectively inserted into both ends of one side of the limiting plate 103. The ends of the two sets of countersunk bolts 105 penetrate the corresponding side surface of the limiting plate 103 and are threaded to the corresponding side end of the U-shaped frame 101. By setting the detachable connector, not only can the connection strength between the limiting plate 103 and the U-shaped frame 101 be guaranteed, but when the limiting plate 103 needs to be disassembled, only the bolts need to be unscrewed. The operation is simple and convenient, and it is easy to maintain or replace the photovoltaic glass body 102.

[0040] The card plate 200 has guide grooves 209 on its lower sides. The tops of the two guide grooves 209 are connected to the inner cavities of the through holes 211. Connecting strips 207 are slidably connected to the inner cavities of the two guide grooves 209. The tops of the two connecting strips 207 are fixedly connected to the bottom of the corresponding side plug-in plate 201. Square holes 210 are formed on the bottom sides of the card plate 200 at corresponding positions of the guide grooves 209. The tops of the two square holes 210 are connected to the inner cavities of the corresponding side guide grooves 209. Paddles 208 are slidably connected to the inner cavities of the two square holes 210. The paddles 208 are fixedly connected to the bottom of the corresponding side connecting strips 207. The guide grooves 209, square holes 210, connecting strips 207, and levers 208 on both sides of plate 200 not only provide guidance for the movement of the plug-in plate 201, but also allow the connecting strips 207 to slide left and right in the guide grooves 209 and the levers 208 to slide in the square holes 210. This allows the plug-in plate 201 to move accurately to both sides and insert into the corresponding cavities 110 under the push of the wedge block 204, preventing the plug-in plate 201 from shifting or getting stuck, thus improving the accuracy and reliability of the connection. At the same time, the levers 208 make it easy for personnel to simultaneously pinch the levers 208 inward, causing both sets of plug-in plates 201 to move inward at the same time, thereby retracting into the inner cavity of the through hole 211.

[0041] The fasteners include C-shaped plates 301 respectively disposed inside two sets of cavities 110. The two sets of C-shaped plates 301 are arranged with their openings facing each other. The backs of the two sets of C-shaped plates 301 are slidably connected to the inner wall of one side of the corresponding cavity 110 via limiting members. A snap-fit ​​block 302 is fixedly connected to the bottom of the upper end of each set of C-shaped plates 301. A snap-fit ​​groove 304 is opened at the top of the facing end of each set of insertion plates 201. Pulling components are respectively provided on the bottom of both sides of the snap-fit ​​plate 200, which pull down the corresponding side C-shaped plate 301 to snap the snap-fit ​​block 302 at the end of the C-shaped plate 301 into the corresponding side snap-fit ​​groove 304. Through the fasteners, the ends of the insertion plates 201 can be further fixed. When the snap-fit ​​block 302 at the end of the shaped plate snaps into the snap-fit ​​groove 304 of the plug-in plate 201, it can effectively prevent the plug-in plate 201 from coming out of the cavity 110, further enhancing the connection strength between the limiting plate 103 and the outer frame 100.

[0042] The pulling assembly includes threaded holes 111 on the bottom of both sides of the clamping plate 200. Both sets of threaded holes 111 are threaded with hexagonal socket head cap screws 303. A connecting rod 306 is fixedly connected to the top of each set of hexagonal socket head cap screws 303. The bottom of each set of C-shaped plates 301 has a corresponding adapter groove 305. The connecting rods 306 are rotatably connected to the inner cavity of the corresponding adapter groove 305. Through the pulling assembly, rotating the hexagonal socket head cap screws 303 allows for easy up-and-down adjustment of the C-shaped plate's position. Simultaneously, it ensures the C-shaped plate remains stable after being adjusted to a suitable position, ensuring that the clamping block 302 can accurately engage with the clamping groove 304 for reliable fixation. Furthermore, the connecting rod 306 is rotatably connected to the adapter groove 305 at the bottom of the C-shaped plate, providing flexibility in the connection between the hexagonal socket head cap screws 303 and the C-shaped plate, adapting to angle changes during movement and ensuring the normal operation of the pulling assembly.

[0043] The limiting component includes limiting grooves 109 respectively opened on the inner wall surfaces of the two sets of cavities 110 facing each other. The inner cavities of the two sets of limiting grooves 109 are slidably connected to limiting strips 300. The two sets of limiting strips 300 are respectively fixedly connected to the back of the corresponding C-shaped plate 301. Through the setting of the limiting component, the design of the limiting grooves 109 and the limiting strips 300, the movement of the C-shaped plate is limited and guided. The limiting strips 300 slide in the limiting grooves 109, so that the C-shaped plate can remain stable during the up and down movement, avoiding the C-shaped plate from shaking or deviating, and ensuring that the snap-fit ​​block 302 can be accurately snapped into the snap-fit ​​groove 304, thereby improving the reliability of the fastener.

[0044] The rotating connection assembly includes a rotating column 106 fixedly installed on one side of the U-shaped frame 101, and a connecting groove 108 is provided on the bottom side of the outer frame 100 at a position corresponding to the rotating column 106. The rotating column 106 is rotatably connected to the inner cavity of the connecting groove 108. Through the setting of the rotating connection assembly, the rotating column 106 on one side of the U-shaped frame 101 in the rotating connection is rotatably connected to the connecting groove 108 on the bottom side of the outer frame 100, so that the U-shaped frame 101 can rotate flexibly relative to the outer frame 100.

[0045] The photovoltaic glass body 102 has a hollow layer 400 in the middle, and the hollow layer 400 is filled with an insulating layer. Through the setting of the hollow layer 400 and the insulating layer, the hollow layer 400 in the middle of the photovoltaic glass body 102 and the insulating layer filled inside can effectively prevent heat transfer, improve the heat insulation performance of the photovoltaic glass, reduce the outdoor heat entering the room in summer, and reduce the indoor heat loss to the outside in winter, thereby reducing the building's energy consumption and achieving the goal of energy saving.

[0046] The insulating layer is made of one of argon, krypton, or xenon, with a filling rate of over 95%, preferably argon. Argon has a density 1.4 times that of air and 10 times that of helium. Furthermore, argon is an inert gas that does not react chemically with other substances at room temperature.

[0047] Working principle;

[0048] First, insert the photovoltaic glass body 102 into the inner cavity of the U-shaped frame 101, and take out the limiting plate 103 and align it with the opening of the U-shaped plate. Then, use two sets of countersunk bolts 105 to penetrate the corresponding side surface of the limiting plate 103 and thread them to the corresponding side end of the U-shaped frame 101 to prevent the photovoltaic glass body 102 from sliding out of the U-shaped frame 101, thus completing the initial fixation.

[0049] Subsequently, the photovoltaic glass body 102 is flipped upwards, so that the card plate 200 fixedly installed at the end of the limiting plate 103 is inserted into the inner cavity of the card groove 107 at the bottom of the outer frame 100.

[0050] At this time, rotating the lead screw 203 causes the wedge block 204 to slide downward in the middle of the through hole 211 due to the threaded engagement between the lead screw 203 and the wedge block 204. The inclined surfaces on both sides of the wedge block 204 contact the plug plate 201. As the wedge block 204 moves downward, it pushes the two sets of plug plates 201 to move to both sides and insert them into the corresponding side cavity 110. At the same time, as the plug plate 201 moves, it drives the paddle 208 to slide in the square hole 210.

[0051] When the restriction on the limiting plate 103 is released, the screw 203 is reversed to push the wedge block 204 upward. Then, the lever 208 is pinched inward at the same time, which drives the two sets of plug plates 201 to move inward at the same time, thereby retracting into the inner cavity of the through hole 211.

[0052] When it is necessary to fix the plug plate 201, rotate the hex socket bolt 303. The connecting rod 306 at the top of the bolt rotates in the transition groove 305 at the bottom of the C-shaped plate, and the hex socket bolt 303 is unscrewed from the threaded hole 111. This pulls the C-shaped plate downward, thereby causing the snap-fit ​​block 302 at the bottom of its upper end to snap into the snap-fit ​​groove 304 opened at the top of the plug plate 201. This fixes the end of the plug plate 201, ensuring that the limiting plate 103 is firmly connected to the outer frame 100, preventing the limiting plate 103 from detaching from the inner cavity of the outer frame 100, and ensuring the stable installation of the photovoltaic glass body 102.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
