Description

Technical Field

[0001] This invention relates to the field of grille technology, and in particular to a photovoltaic integrated ventilation, lighting and rainproof grille. Background Technology

[0002] A photovoltaic (PV) power generation ventilation and lighting grille is a type of grille that utilizes a photovoltaic power generation system. Current technologies typically employ light-transmitting photovoltaic glass to achieve PV power generation, thus ensuring the grille's lighting performance. However, existing PV grilles lack the ability to provide both ventilation and rain protection.

[0003] Chinese invention application number CN202310012751.4 discloses a soundproof ventilation grille with photovoltaic function. It combines ventilation and rain protection by setting a photovoltaic panel with a rotatable louver structure. However, the frequently rotating split photovoltaic grille is prone to damage during use, which is not conducive to improving the stability of the photovoltaic grille. Summary of the Invention

[0004] The present invention proposes a photovoltaic integrated ventilation, lighting and rain shelter grille, the purpose of which is to solve the problem that the frequently rotating separate photovoltaic grille in the traditional technology is prone to damage during use, which is not conducive to improving the stability of the photovoltaic grille.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A photovoltaic integrated ventilation, lighting, and rain-sheltered grille includes:

[0007] A mounting frame, on which multiple photovoltaic grids are fixedly connected at intervals;

[0008] The shielding mechanism includes a sliding frame, a sealing frame, a sealing plate, a sealing cavity, and a pneumatic component. Sliding grooves are provided on both sides of the bottom of the mounting frame. Sliding frames are slidably connected to each of the two sliding grooves. Multiple receiving grooves are provided on each of the two sliding frames. Sealing frames are slidably and sealingly connected to each of the multiple receiving grooves. The same light-transmitting glass is fixedly connected to two corresponding sealing frames on the two sliding frames. The multiple light-transmitting glass panes correspond one-to-one with the adjacent gaps of multiple photovoltaic grids. Sealing plates are fixedly connected to the bottom of each of the multiple sealing frames. Sealing grooves are connected to the bottom of each of the multiple receiving grooves. Sealing plates are slidably and sealingly connected to the sealing grooves one-to-one. A sealing cavity is formed between the inner periphery of the receiving groove, the bottom of the sealing frame, and the sealing plate. Ventilation grooves are connected to the bottom of multiple sealing cavities on the same side. Ventilation grooves on the same side are connected to the same connecting groove. A pneumatic component is connected to one end of each of the two connecting grooves.

[0009] Preferably, each of the multiple sealing frames is photovoltaic-connected to a reset spring at its bottom, and the bottom end of the reset spring is fixedly connected to the bottom of the receiving groove.

[0010] Preferably, the plurality of ventilation slots and the two connecting slots are all formed in the sliding frame, wherein the two connecting slots are arranged through one end of the same type of slot.

[0011] Preferably, the pneumatic assembly includes a connecting pipe, a piston rod, and an electric telescopic rod. The connecting pipe is fixedly connected to the sliding frame and communicates with the connecting groove. The piston rod is slidably connected inside the connecting pipe. The electric telescopic rod is installed at one end inside the sliding groove, and the output end of the electric telescopic rod is coaxially and fixedly connected to the piston rod.

[0012] Preferably, each of the two connecting slots is equipped with a solenoid valve, and the plurality of solenoid valves and electric telescopic rods are electrically connected to a controller, which is installed in the mounting frame.

[0013] Preferably, each of the two sliding grooves is connected to a buffer assembly at the end away from the pneumatic component. The buffer assembly includes a buffer block and a buffer spring. The buffer block is slidably connected in the sliding groove, and a buffer spring is fixedly connected between the buffer block and the end of the sliding groove. The buffer block and the buffer spring provide a buffer protection effect for the sliding frame that moves to the end in the sliding groove, so as to avoid the sliding frame from colliding with the inside of the sliding groove when the sealing frame changes from moving up and down to moving along the sliding groove with the sliding frame.

[0014] Preferably, each of the multiple sealing frames is connected to a guide assembly, which includes a rotating seat, a rotating shaft, and a guide wheel. The rotating seat is fixedly connected to the sealing frame, and the rotating shaft is fixedly connected to the rotating seat. The guide wheel is coaxially rotatably connected to the rotating shaft, and the top of the guide wheel abuts against the lower surface of the photovoltaic grid. Through the guiding effect of the guide wheel, the friction between the gap sealing frame and the photovoltaic grid as the sliding frame moves along the sliding groove effectively separates the light-transmitting glass and the photovoltaic grid, thus providing protection for the light-transmitting glass and the photovoltaic grid.

[0015] Preferably, the top of each of the two sliding grooves is connected to a plurality of gap grooves, and the plurality of gap grooves correspond one-to-one with the adjacent gaps of the plurality of photovoltaic grids. By setting the gap grooves to accommodate the guide components, interference is avoided when the guide components are deployed and retracted from the light-transmitting glass.

[0016] Preferably, sealing strips are fixedly connected to the periphery of each of the multiple transparent glass panes, and the gaps between the transparent glass panes and the adjacent photovoltaic grids are matched. The sealing strips further improve the sealing performance when the transparent glass panes are inserted into the gaps of the photovoltaic grids, preventing rainwater from falling through the gaps between the transparent glass panes and the photovoltaic grids, thus improving the rain protection effect.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This invention, by setting up a shading mechanism, initially positions multiple translucent glass panes below multiple photovoltaic grids, thereby making the gaps between adjacent photovoltaic grids transparent and facilitating ventilation. When the shading mechanism is in operation, the multiple translucent glass panes can move to the gaps between multiple photovoltaic grids to achieve rain protection and photovoltaic power generation through the photovoltaic grids. At the same time, the light transmission effect of the transparent photovoltaic grids and translucent glass completes the lighting effect below.

[0019] 2. This invention, by setting up a pneumatic component, overcomes the friction between the sliding frame and the sliding groove under the action of pneumatic transmission, pushes the sliding frame to move the light-transmitting glass to below the gap between adjacent photovoltaic grids, and causes the sealing cavity to expand and extend, thereby driving the light-transmitting glass on the sealing frame to move upward and into the adjacent gaps of multiple photovoltaic grids. With the sealing assistance of the sealing strip, multiple closely fitted and spaced light-transmitting glasses and photovoltaic grids complete the comprehensive sealing effect of the mounting frame, and finally achieve the rain protection effect below the mounting frame.

[0020] 3. By setting up an electromagnetic valve, the present invention can isolate the ventilation groove by controlling the electromagnetic valve to close, maintain the stable air pressure in the sealed cavity, avoid the fluctuation of the output end of the electric telescopic rod from affecting the stability of the air pressure in the sealed cavity, improve the stability of the light-transmitting glass when performing rain shelter operation, and reduce the workload of the electric telescopic rod.

[0021] 4. By setting up a pneumatic component, under the action of pneumatic transmission and the elastic force of the return spring, the sealing cavity gradually contracts and recovers, and overcomes the friction between the sliding frame and the sliding groove, pulling the sliding frame to move in the sliding groove to return to its original position, thus completing the automatic retraction operation of the light-transmitting glass.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figure 1 A photovoltaic integrated ventilation, lighting, and rainproof grille, comprising:

[0032] Mounting frame 1, on which multiple photovoltaic grilles 2 are fixedly connected at intervals; wherein the photovoltaic grilles 2 adopt photovoltaic glass in the existing technology, so as to achieve photovoltaic power generation while ensuring light transmission.

[0033] Reference Figures 2-4 The shading mechanism includes a sliding frame 4, a sealing frame 6, a sealing plate 10, a sealing cavity 12, and a pneumatic component. Sliding grooves 3 are provided on both sides of the bottom of the mounting frame 1. Sliding frames 4 are slidably connected in both sliding grooves 3. Multiple receiving grooves 5 are provided on both sliding frames 4. Sealing frames 6 are slidably connected in both receiving grooves 5. The same light-transmitting glass 8 is fixedly connected to the two corresponding sealing frames 6 on the two sliding frames 4. The gaps between the multiple light-transmitting glass 8 and the multiple photovoltaic grids 2 are one-to-one. Sealing plates 10 are fixedly connected to the bottom of the multiple sealing frames 6.

[0034] Reference Figures 5-7 The bottom of each of the multiple receiving slots 5 is connected to a sealing slot 11, and the multiple sealing plates 10 are slidably connected to the sealing slot 11 in a corresponding manner. The inner periphery of the receiving slot 5, the bottom of the sealing frame 6, and the sealing plate 10 form a sealing cavity 12. The bottom of the multiple sealing cavities 12 on the same side is connected to a venting slot 14, and the multiple venting slots 14 on the same side are connected to the same connecting slot 15. One end of each of the two connecting slots 15 is connected to a pneumatic component.

[0035] The light-transmitting glass 8 is made of colorless and transparent glass to ensure light transmission.

[0036] Each of the multiple sealing frames 6 has a photovoltaic connection to a reset spring 13 at its bottom. The bottom end of the reset spring 13 is fixedly connected to the bottom of the receiving groove 5. The reset spring 13 is initially in a natural state and is used to restore the sealing frame 6 to its original position after the sealing frame 6 moves upward, thus completing the subsequent retraction operation of the light-transmitting glass 8.

[0037] Multiple ventilation slots 14 and two connecting slots 15 are all opened in the sliding frame 4, with the two connecting slots 15 having a through-type arrangement at the same end.

[0038] The pneumatic assembly includes a connecting pipe 16, a piston rod 17, and an electric telescopic rod 18. The connecting pipe 16 is fixedly connected to the sliding frame 4 and communicates with the connecting groove 15. The piston rod 17 is slidably connected inside the connecting pipe 16. The electric telescopic rod 18 is installed at one end inside the sliding groove 3, and the output end of the electric telescopic rod 18 is coaxially and fixedly connected to the piston rod 17.

[0039] Solenoid valves 26 are installed in both connecting slots 15. Multiple solenoid valves 26 and electric telescopic rods 18 are electrically connected to controllers. The controllers are installed in the mounting frame 1 and are electrically connected to an external power supply. The controllers are independently connected in series with the two electric telescopic rods 18 and independently connected in series with the two solenoid valves 26.

[0040] Both sliding grooves 3 have a buffer assembly connected to the end away from the pneumatic component. The buffer assembly includes a buffer block 19 and a buffer spring 20. The buffer block 19 is slidably connected in the sliding groove 3, and the buffer spring 20 is fixedly connected between the buffer block 19 and the end of the sliding groove 3. The buffer block 19 is made of sponge. The buffer block 19 and the buffer spring 20 form a buffer protection effect for the sliding frame 4 that moves to the end in the sliding groove 3.

[0041] Multiple sealing frames 6 are each connected to a guide assembly, which includes a rotating seat 21, a rotating shaft 22, and a guide wheel 23. The rotating seat 21 is fixedly connected to the sealing frame 6, and the rotating shaft 22 is fixedly connected to the rotating seat 21. The guide wheel 23 is coaxially rotatably connected to the rotating shaft 22. The top of the guide wheel 23 abuts against the lower surface of the photovoltaic grid 2. Through the guiding and separating effect of the guide wheel 23, the light-transmitting glass 8 is effectively prevented from colliding with the photovoltaic grid 2 when it is moved, thus protecting the light-transmitting glass 8 and the photovoltaic grid 2.

[0042] The top of each of the two sliding grooves 3 is connected to multiple gap grooves 24. The multiple gap grooves 24 correspond one-to-one with the adjacent gaps of multiple photovoltaic grids 2. By setting the gap grooves 24, when the light-transmitting glass 8 is driven to move upward to the gap of the photovoltaic grid 2, the guide component is accommodated, thus avoiding interference caused by the guide component.

[0043] Multiple transparent glass panes 8 are fixedly connected to sealing strips 25 on all sides. The gaps between the transparent glass panes 8 and the adjacent photovoltaic grids 2 are matched. The sealing strips 25 further improve the sealing performance when the transparent glass panes 8 are inserted into the gaps of the photovoltaic grids 2, thereby improving the rain protection effect.

[0044] In use, in the initial state, multiple translucent glass 8 are located below multiple photovoltaic grids 2, so that the gaps between the adjacent photovoltaic grids 2 are transparent, which facilitates the formation of ventilation effect and the photovoltaic power generation effect is achieved through the photovoltaic grids 2. At the same time, the light transmission effect of the transparent photovoltaic grids 2 and the translucent glass 8 completes the lighting effect below.

[0045] When rain shelter is required, the controller puts two solenoid valves 26 into the conducting state and activates two electric telescopic rods 18. The output ends of the two electric telescopic rods 18 extend, pushing the piston rod 17 to slide into the connecting pipe 16, compressing the space inside the connecting pipe 16 and increasing the air pressure in the connecting pipe 16, connecting groove 15, ventilation groove 14, and sealing cavity 12. At this time, because the sealing frame 6 is pressed against the bottom of the photovoltaic grid 2 by the guide component, the sealing cavity 12 cannot be extended. When the pushing force of the piston rod 17 on the air pressure in the connecting pipe 16 is greater than the friction between the sliding frame 4 and the sliding groove 3, the sliding frame 4 is pushed to move in the sliding groove 3 until the sliding frame 4 moves. Multiple sealing frames 6 on the moving frame 4 move to the adjacent gap groove 24. At this time, the guide component moves into the gap groove 24 along the top of the sliding groove 3. The light-transmitting glass 8 moves to the gap below the adjacent photovoltaic grid 2. Under the action of pneumatic transmission, it overcomes the elastic force of the reset spring 13, causing the sealing cavity 12 to expand and extend, thereby driving the light-transmitting glass 8 on the sealing frame 6 to move upward. Multiple light-transmitting glass 8 move upward and get into the adjacent gaps of multiple photovoltaic grids 2. With the sealing assistance of the sealing strip 25, multiple closely fitted and spaced light-transmitting glass 8 and photovoltaic grid 2 complete the full sealing effect of the mounting frame 1, and finally achieve the rain protection effect below the mounting frame 1.

[0046] At this time, the solenoid valve 26 is closed by the controller, which isolates the ventilation groove 14, keeps the air pressure in the sealed cavity 12 stable, avoids the fluctuation of the output end of the electric telescopic rod 18 from affecting the air pressure stability in the sealed cavity 12, improves the stability of the light-transmitting glass 8 when performing rain shelter operation, and reduces the workload of the electric telescopic rod 18.

[0047] After the rain shelter operation is completed, the solenoid valve 26 is activated again by the controller, which controls the output end of the electric telescopic rod 18 to retract. The piston rod 17 moves back and the space inside the connecting pipe 16 gradually recovers. Under the elastic force of the return spring 13, the sealing frame 6 drives the light-transmitting glass 8 to move downward and retract into the receiving groove 5. The air pressure in the sealing cavity 12 gradually recovers. When the output end of the electric telescopic rod 18 continues to retract, the piston rod 17 gradually stretches the space inside the connecting pipe 16, causing the air pressure in the connecting pipe 16, the connecting groove 15, the ventilation groove 14 and the sealing cavity 12 to decrease. When the pulling force of the piston rod 17 on the air pressure inside the connecting pipe 16 is greater than the friction between the sliding frame 4 and the sliding groove 3, the sliding frame 4 is pulled to move back to its original position in the sliding groove 3, completing the retraction operation of the light-transmitting glass 8.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
