Description

Technical Field

[0001] This utility model relates to the field of photovoltaic buildings, specifically a photovoltaic panel connection structure. Background Technology

[0002] In the current construction industry, the application of photovoltaic power generation technology is becoming increasingly widespread, especially in the development of facade photovoltaic glass. However, existing photovoltaic power generation systems have certain shortcomings in the connection structure of balcony photovoltaic railings. Currently, the commonly used curtain wall glass photovoltaic power generation system utilizes the curtain wall keel to conceal the connection with the power generation equipment. This method, through the design of dedicated channels within the keel, safely hides the wires and connectors, ensuring both the concealment of the wiring and improving overall safety. However, as a component that combines enclosure and power generation functions, the connection method between balcony photovoltaic railings and the power generation equipment presents the following problems: Firstly, because balcony photovoltaic glass is usually arranged in a decentralized manner, the concealment method of the curtain wall keel cannot be directly adopted, resulting in the connection between the balcony photovoltaic glass and the power generation equipment not being completely concealed. Secondly, since balconies are areas with frequent human activity, and balcony photovoltaic railings are often located in easily accessible areas, the decentralized circuit layout easily leads to exposed wires, increasing safety hazards.

[0003] Therefore, it is necessary to develop a photovoltaic panel connection structure that can effectively hide the connection between the balcony photovoltaic panel and the power generation equipment, while ensuring the safety and concealment of the wiring layout and reducing safety hazards. Utility Model Content

[0004] To address the problem mentioned above regarding the inability to completely conceal the connection parts in the existing balcony photovoltaic panel connection structure, the technical solution adopted by this utility model is as follows:

[0005] A photovoltaic (PV) fence connection structure includes a PV fence and a power generation component connected to the PV fence. The structure also includes a wiring conduit for wiring between the PV fence and the power generation component. Both the power generation component and the wiring conduit are pre-installed within the floor slab. The connection point between the PV fence and the wiring is located outside the floor slab and below the floor surface.

[0006] Furthermore, the photovoltaic panel connection structure described in the solution also includes a shielding layer extending outward from the floor slab and used to fix the photovoltaic panel. The shielding layer has an inner cavity, and the wire connection of the photovoltaic panel is located in the inner cavity of the shielding layer. The shielding layer is detachably connected to the floor slab.

[0007] Furthermore, in the photovoltaic panel connection structure described in the solution, the photovoltaic panel is also provided with a quick connector for connecting to electrical wires, the quick connector being located between the bottom of the shading layer and the surface of the floor slab.

[0008] Furthermore, in the photovoltaic panel connection structure described in the solution, the line conduit includes a first conduit embedded in the floor slab, and a second conduit connected to the first conduit and extending outward from the floor slab. The second conduit is arranged along the outer side of the floor slab in a direction away from the floor slab surface. The second conduit is located between the bottom of the shading layer and the floor slab surface, and the quick-connect joint portion is located inside the second conduit.

[0009] Furthermore, the photovoltaic panel connection structure described in the solution also includes a hidden layer located on the opposite side of the floor surface. The hidden layer has a hidden layer cavity. The power generation component includes a switch junction box pre-installed in the floor, a photovoltaic auxiliary component connected to the switch junction box, and a power distribution system connected to the photovoltaic auxiliary component. The photovoltaic auxiliary component is located in the hidden layer cavity.

[0010] Furthermore, in the photovoltaic panel connection structure described in the solution, the hidden layer has an opening on its side.

[0011] Furthermore, in the photovoltaic panel connection structure described in the solution, the wiring conduit further includes a third conduit located within the hidden layer cavity, the third conduit being used for wiring between the photovoltaic auxiliary components and the power distribution system.

[0012] Furthermore, in the photovoltaic panel connection structure described in the solution, the second conduit is a flexible metal tube, and a waterproof component is provided at the outlet of the second conduit.

[0013] Furthermore, in the photovoltaic panel connection structure described in the solution, the second conduit is located inside the shading layer cavity, and the quick-connect connector is located inside the second conduit.

[0014] Furthermore, in the photovoltaic panel connection structure described in the solution, the width of the hidden layer is not less than 200mm and the height is not less than 150mm.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention effectively conceals the connection lines between the photovoltaic panel and the power generation components by pre-embedding the power generation components and wiring conduits within the floor slab, avoiding the problem of exposed wires and improving overall safety and aesthetics. Furthermore, the connection point between the photovoltaic panel and the wiring is located outside the floor slab and below its surface, preventing people from touching the connection point while on the balcony, further enhancing overall safety.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figure 1-4 The photovoltaic panel connection structure shown includes a photovoltaic panel 1 and a power generation component 2 connected to the photovoltaic panel 1. It also includes a wiring conduit 3 for wiring between the photovoltaic panel 1 and the power generation component 2. The power generation component 2 and the wiring conduit 3 are both pre-installed in the floor slab. The connection point between the photovoltaic panel 1 and the wire is located on the outside of the floor slab and is lower than the floor surface.

[0024] This utility model effectively conceals the connection lines between the photovoltaic panel 1 and the power generation component 2 by pre-embedding the power generation component 2 and the wiring conduit 3 inside the floor slab, avoiding the problem of exposed wires and improving the overall safety and aesthetics. At the same time, the connection point between the photovoltaic panel 1 and the wire is located on the outside of the floor slab and below the floor surface. This design avoids the risk of people touching the connection point when they are on the balcony, further improving the overall safety.

[0025] This invention improves the safety and aesthetics of a balcony photovoltaic power generation system by setting up a photovoltaic railing connection structure. Specifically, the structure embeds the power generation component 2 and the wiring conduit 3 inside the floor slab. This not only effectively hides the connection lines between the photovoltaic railing 1 and the power generation device 2, completely solving the problem of exposed wires and prominent safety hazards in traditional balcony photovoltaic railings, but also makes the entire photovoltaic power generation system layout neater and more aesthetically pleasing, perfectly blending with the building's appearance. Furthermore, by placing the connection point between the photovoltaic railing 1 and the wiring on the outside of the floor slab and below the floor surface, this invention avoids the risk of people touching the connection point while on the balcony, greatly improving safety.

[0026] Furthermore, such as Figure 1-4The photovoltaic fence connection structure shown includes a shielding layer 4 extending out of the floor slab and used to fix the photovoltaic fence 1. The shielding layer 4 has a shielding layer cavity 41. The wire connection of the photovoltaic fence 1 is located in the shielding layer cavity 41. The shielding layer 4 is detachably connected to the floor slab.

[0027] This utility model improves the concealment and safety of the connection between the photovoltaic panel 1 and the power line by adding a shielding layer 4, which effectively prevents people from accidentally touching the power line connection when they are on the balcony, reduces safety hazards, and also enhances the overall aesthetics. Furthermore, the shielding layer 4 not only completely covers the power line connection of the photovoltaic panel 1, but also connects to the floor slab in a detachable manner, which facilitates subsequent maintenance and repair.

[0028] Furthermore, such as Figure 1-4 The photovoltaic panel 1 is shown as a photovoltaic panel connection structure, wherein the photovoltaic panel 1 is further provided with a quick connector 11 for connecting to electrical wires, and the quick connector 11 is located between the bottom of the shielding layer 4 and the surface of the floor slab.

[0029] This utility model simplifies the connection process between the wires and the photovoltaic panel 1 by setting a quick connector 11 on the photovoltaic panel 1, thereby improving the connection efficiency and convenience. Furthermore, the quick connector 11 is located between the bottom of the shielding layer 4 and the surface of the floor slab, which facilitates installation and wiring while ensuring the concealment and safety of the connection. In addition, the setting of the quick connector 11 optimizes the installation and maintenance process of the photovoltaic panel 1, reducing the difficulty and cost of operation.

[0030] Furthermore, such as Figure 1-4 The photovoltaic panel connection structure shown includes a first conduit 31 embedded in the floor slab and a second conduit 32 connected to the first conduit 31 and extending out of the floor slab. The second conduit 32 is arranged along the outside of the floor slab in a direction away from the floor slab surface. The second conduit 32 is located between the bottom of the shielding layer 4 and the floor slab surface. The quick connector 11 is partially located inside the second conduit 32.

[0031] This utility model, by setting the second conduit 32 along the outer side of the floor slab away from the floor slab surface, and with the second conduit 32 located between the bottom of the shielding layer 4 and the floor slab surface, not only better hides the wires, but also allows the quick-connect connector 11 part to be located inside the second conduit 32, further concealing the connection between the wires and the photovoltaic panel 1, effectively preventing external interference, ensuring the stability and safety of the connection, and also improving the overall aesthetics and safety performance.

[0032] Furthermore, such as Figure 1-4The photovoltaic panel connection structure shown includes a hidden layer 5 located on the opposite side of the floor surface. The hidden layer 5 has a hidden layer cavity 51. The power generation component 2 includes a switch junction box 21 pre-installed in the floor, a photovoltaic auxiliary component 22 connected to the switch junction box 21, and a power distribution system connected to the photovoltaic auxiliary component 22. The photovoltaic auxiliary component 22 is located in the hidden layer cavity 51.

[0033] This invention improves the overall concealment and aesthetics of the photovoltaic power generation system by setting a hidden layer 5 on one side of the floor slab surface and pre-installing the photovoltaic auxiliary component 22 in the inner cavity 51 of the hidden layer. Furthermore, by placing the hidden layer 5 on the top of the next floor, this design not only effectively prevents people from accidentally touching the photovoltaic auxiliary component 22 during activities, reducing safety hazards, but also facilitates subsequent maintenance and repair work, improving overall ease of use. Furthermore, the hidden layer 5 not only provides a safe installation environment for the photovoltaic auxiliary component 22, but also avoids interference from external factors, ensuring the stable operation of the system.

[0034] Furthermore, such as Figure 1-4 The diagram shows a photovoltaic panel connection structure, wherein the hidden layer 5 has an opening on its side.

[0035] This invention provides an opening on the side of the hidden layer 5, allowing for inspection or maintenance of the photovoltaic auxiliary components 22 within the hidden layer 5. This not only facilitates maintenance operations for operators but also reduces maintenance costs and time, thereby improving the maintainability of the system.

[0036] Furthermore, such as Figure 1-4 The diagram shows a photovoltaic panel connection structure, wherein the line conduit 3 further includes a third conduit 33 located in the inner cavity 51 of the hidden layer, the third conduit 33 being used for wiring between the photovoltaic auxiliary module 22 and the power distribution system.

[0037] This invention utilizes a third conduit 33 within the concealed layer cavity 51 for wiring between the photovoltaic auxiliary module 22 and the power distribution system. This arrangement further standardizes the wiring layout and improves the system's safety and tidiness. Furthermore, the third conduit 33 effectively protects the wires from external environmental corrosion and ensures their concealment, avoiding safety hazards caused by exposed wires. Moreover, this arrangement prevents operators from accidentally touching the wires during subsequent inspections or maintenance of the photovoltaic auxiliary module 22, thus further enhancing system safety.

[0038] Furthermore, such as Figure 1-4The diagram shows a photovoltaic panel connection structure, wherein the second conduit 32 is a metal flexible tube, and a waterproof component is provided at the outlet of the second conduit 32.

[0039] In this invention, the second conduit 32 is made of metal flexible tubing. Metal flexible tubing has good flexibility and corrosion resistance, and can adapt to various complex installation environments, thereby improving the service life of the second conduit 32. Furthermore, by setting a waterproof component at the outlet of the second conduit 32, the waterproof performance of the wire connection is enhanced, effectively preventing rainwater or other liquids from seeping in, ensuring the safe and stable operation of the photovoltaic power generation system, and further extending the service life of the system.

[0040] Furthermore, such as Figure 1-4 The diagram shows a photovoltaic panel connection structure, wherein the second conduit 32 is located in the inner cavity 41 of the shading layer, and the quick connector 11 is located inside the second conduit 32.

[0041] The present invention places the second conduit 32 in the inner cavity 41 of the shielding layer. This arrangement provides an additional protective barrier for the wire connection, avoiding direct contact and interference from the outside world. Furthermore, the quick connector 11 is placed inside the second conduit 32. This arrangement not only further enhances the concealment and safety of the connection between the wire and the photovoltaic panel 1, but also reduces the risk of damage caused by external forces.

[0042] Furthermore, such as Figure 1-4 The photovoltaic panel connection structure shown has a hidden layer 5 with a width of not less than 200mm and a height of not less than 150mm.

[0043] The hidden layer 5 in this invention, with a width of not less than 200mm and a height of not less than 150mm, ensures sufficient installation space for the photovoltaic auxiliary module 22, avoiding installation difficulties or performance limitations caused by limited space. Furthermore, this design also ensures sufficient space for technicians to easily inspect, repair, or replace the photovoltaic auxiliary module 22 located in the inner cavity 51 of the hidden layer, thereby reducing maintenance difficulty and cost. Furthermore, if the width of the hidden layer 5 is less than 200mm, it may restrict the installation space of the photovoltaic auxiliary module 22, affecting the overall performance of the system. Furthermore, if the height of the hidden layer 5 is less than 150mm, it will also cause inconvenience to inspection and maintenance work, increasing maintenance difficulty and cost.

[0044] Furthermore, such as Figure 1-4 The diagram shows a photovoltaic panel connection structure, wherein the first conduit 31 is a PVC pipe and the third conduit 33 is a JDG pipe.

[0045] The first conduit 31 in this invention is made of PVC pipe because PVC pipe has good insulation and corrosion resistance, which can effectively protect the wire from external environmental erosion. Since the first conduit 31 is buried in cement for a long time, the use of PVC pipe can better adapt to harsh environments such as humidity and acid and alkali, ensuring the normal use of the wire. Furthermore, the third conduit 33 is made of JDG pipe because JDG pipe has good mechanical properties and fire resistance. Since the third conduit 33 is located in the hidden layer for a long time, operators need to frequently maintain and inspect the photovoltaic auxiliary components in the hidden layer. Therefore, the use of JDG pipe can prevent the wire connection from becoming loose during maintenance and inspection, and also improve the fire safety performance of the wire.

[0046] like Figure 1-4 As shown, the implementation method of this embodiment is as follows:

[0047] Example 1:

[0048] During the installation of the photovoltaic connection structure, the switch junction box 21 and the first conduit 31 are pre-installed within the floor slab before cement is poured. The first conduit 31 is made of PVC pipe to withstand the harsh environment of being embedded in cement. Subsequently, the wires connecting the switch junction box 21 to the photovoltaic panel 1 are led out to the outside of the floor slab through the first conduit 31, while the wires connecting the switch junction box 21 to the photovoltaic auxiliary components 22 are led out to the opposite side of the floor slab surface. Then, cement is poured to embed the switch junction box 21 and the first conduit 31 into the floor slab.

[0049] Next, the portion of the first conduit 31 extending outside the floor slab is connected to the second conduit 32, which extends along the outer side of the floor slab, ensuring its outlet is close to the quick-connect connector 11 of the photovoltaic panel 1. The photovoltaic panel 1 is then fixed to the outer side of the floor slab and connected to the wiring of the connecting switch junction box 21 via the quick-connect connector 11. The quick-connect connector 11 is concealed within the second conduit 32, and a waterproof component is installed at the outlet of the second conduit 32 to enhance the waterproof performance of the quick-connect connector 11. Then, a shielding layer 4 is installed on the outer side of the floor slab, concealing the second conduit 32 within the inner cavity 41 of the shielding layer. The second conduit 32 is made of flexible metal tubing, which, due to its good flexibility and corrosion resistance, can adapt to complex installation environments.

[0050] In addition, the photovoltaic auxiliary module 22 is connected to the switch junction box 21 via wires, and then the photovoltaic auxiliary module 22 is fixed to the opposite side of the floor slab surface and tightly attached to the floor slab. Next, the concealed layer 5 is installed on this side. The concealed layer 5 has an opening on its side for inspection and maintenance, and is 200mm wide and 150mm high to accommodate the photovoltaic auxiliary module 22 and its related wiring and accessories. Finally, the wire at the other end of the photovoltaic auxiliary module 22 is threaded into the third conduit 33, and the wire is guided through the third conduit 33 to the power distribution system for connection, thus completing the installation. The third conduit 33 uses JDG pipe to improve mechanical and fire resistance.

[0051] Example 2:

[0052] This embodiment is similar to the one in Embodiment 1 in terms of features and installation steps, except that the photovoltaic panel 1 is not directly fixed to the outside of the floor slab. Instead, after the shielding layer 4 is installed, the photovoltaic panel 1 is connected to the wires of the connecting switch junction box 21 via the quick connector 11, and a waterproof component is installed at the outlet of the second conduit 32, the photovoltaic panel 1 is then fixed to the shielding layer 4.

[0053] Example 3:

[0054] This embodiment is similar to the one in Embodiment 1 in terms of features and installation steps, except that the width of the hidden layer 5 is 250mm and the height is 200mm.

[0055] Example 4:

[0056] This embodiment is similar to the features and installation steps in Embodiment 1, except that the outlet of the second conduit 32 is set downwards, and the plug-in part of the quick connector 11 is set outside the second conduit 32 to facilitate the operator to plug and unplug the quick connector 11.

[0057] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
