Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of photovoltaic, in particular, to a connecting piece and a photovoltaic system. BACKGROUND

[0002] In a photovoltaic system, a photovoltaic support is usually connected and fixed to a building installation surface through a connecting piece such as a column foot. These connecting pieces need to bear the force from the support and photovoltaic components, and therefore, the fixing effect of the connecting piece on the installation surface has an important influence on the safety and stability of the entire photovoltaic system.

[0003] In the related art, in order to ensure the fixing effect of the connecting piece on the installation surface, the connecting piece may need to penetrate the installation surface when it is installed to the installation surface, which will cause great damage to the building structure and lead to water leakage problems. CONTENT OF THE INVENTION

[0004] The problem solved by the present disclosure is how to reduce the damage caused by the connecting piece to the building structure during installation.

[0005] To solve the above problems, the present disclosure provides a connecting piece and a photovoltaic system.

[0010] Optionally, the plugging piece is movably installed on the connecting piece body.

[0011] Optionally, the plugging piece comprises:

[0012] a cover plate, the cover plate being provided at the outer end of the exhaust passage;

[0013] a first elastic piece, two ends of the first elastic piece being connected to the cover plate and the connecting piece body respectively.

[0014] Optionally, the exhaust passage comprises a through hole provided on the wall portion of the connecting piece body; the first elastic piece is provided through the through hole, one end of the first elastic piece being connected to the cover plate and the other end being fixed to the inside of the connecting piece body.

[0015] Optionally, an inner portion of the connecting member body is provided with a connecting plate, the connecting plate is opposite to the exhaust channel and is connected to an inner wall surface of the connecting member body through a connecting column, and an end of the first elastic member away from the cover plate is connected to the connecting plate.

[0016] Optionally, a side surface of the cover plate away from the connecting member body is provided with a pull ring.

[0017] Optionally, a side surface of the cover plate close to the connecting member body is provided with a sealing gasket.

[0018] Optionally, an outer wall surface of the connecting member body is provided with a connecting wall, and the connecting wall is arranged around the exhaust channel.

[0019] Optionally, an outer end of the exhaust channel is formed with an outer communication opening communicating with an outside of the connecting member body, and a side wall of the exhaust channel is formed with an inner communication opening communicating with the slot.

[0020] The sealing member comprises:

[0021] a sealing block movably arranged in the exhaust channel to connect or disconnect the outer communication opening and the inner communication opening;

[0022] a second elastic member, one end of the second elastic member is connected to an inner end of the exhaust channel, and the other end is connected to the sealing block.

[0023] Optionally, the exhaust channel comprises an exhaust column penetrating through a wall portion of the connecting member body.

[0024] Optionally, the sealing member further comprises a gas plug arranged in the outer communication opening.

[0025] Optionally, a periphery of the slot is provided with a sealing rubber layer, and the slot is sealingly connected to the mounting surface through the sealing rubber layer.

[0026] In a second aspect, the present disclosure provides a photovoltaic system, comprising a support structure, a photovoltaic assembly and the connecting member as described above, the support structure is connected to the connecting member, and the photovoltaic assembly is mounted on the support structure.

[0027] The beneficial effects of the connector disclosed herein are as follows: Since the groove can abut against the mounting surface to form a sealed cavity, and the exhaust channel on the connector body is connected to the outside of the groove and the connector body, the sealed cavity can exhaust air through the exhaust channel. At the same time, since the sealing element is located in the exhaust channel, the exhaust channel can be blocked or opened by operating the sealing element to isolate or connect the sealed cavity with the outside air. Therefore, when the connector needs to be installed on the mounting surface, the exhaust channel can be opened by the sealing element after the groove abuts against the mounting surface, and the air in the sealed cavity can be extracted by the air suction device to form a negative pressure in the sealed cavity, thereby causing the connector body to be adsorbed onto the mounting surface. This achieves the adsorption fixation of the connector on the mounting surface, eliminating the need to penetrate the entire mounting surface. This helps to reduce the damage to the building structure and reduce the risk of water leakage at the building mounting surface. Attached Figure Description

[0051] It should be noted that the terms "one" and "more" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0052] This disclosure provides a connector and a photovoltaic system to reduce the damage to the building structure caused by the connector during installation. Detailed description is provided below with reference to specific embodiments. Figures 1 to 8 This is a schematic diagram of the first embodiment of the connector. Figures 9 to 16 This is a schematic diagram of a second embodiment of the connector.

[0053] like Figures 1-3 , Figures 10-12 As shown, the present disclosure provides a connector 10, including a connector body 11, an exhaust duct 12, and a sealing member 13; the connector body 11 is provided with a groove 111, the groove 111 abuts against the mounting surface 20 to form a sealed cavity 112; the exhaust duct 12 is provided on the connector body 11 to connect the groove 111 and the outside of the connector body 11; the sealing member 13 is provided on the exhaust duct 12 for sealing or opening the exhaust duct 12.

[0054] Specifically, the connector 10 can be a column base, and the mounting surface 20 can be the roof of a building. Regarding the statement that the slot 111 abuts against the mounting surface 20 to form a sealed cavity 112, this means that the slot 111 is covered by the mounting surface 20, thus sealing the space inside the slot 111 into a closed sealed cavity 112. It should be noted that since the sealing member 13 is located in the exhaust duct 12, the exhaust duct 12 can be blocked or opened by operating the sealing member 13. When the exhaust duct 12 is blocked, the sealed cavity 112 is isolated from the outside; when the exhaust duct 12 is opened, the sealed cavity 112 is connected to the outside. Furthermore, it is understood that when the exhaust duct 12 is opened, for example, a suction device 30 (see reference...) can be used. Figure 4 and Figure 5 , Figure 13 and Figure 14 Air is drawn out of the sealed cavity 112 through the exhaust duct 12 to create a negative pressure inside the sealed cavity 112. When air intake stops, the exhaust duct 12 can be immediately sealed by the sealing member 13 to ensure that the sealed cavity 112 is in a stable negative pressure state. In addition, the sealing member 13 can be installed on the connector body 11 in a detachable or movable manner to correspondingly seal or open the exhaust duct 12.

[0055] In this embodiment, since the slot 111 can abut against the mounting surface 20 to form a sealed cavity 112, and the exhaust duct 12 on the connector body 11 is connected to the outside of the slot 111 and the connector body 11, the sealed cavity 112 can exhaust air outward through the exhaust duct 12. At the same time, since the sealing member 13 is provided in the exhaust duct 12, the exhaust duct 12 can be blocked or opened by operating the sealing member 13 to isolate or connect the sealed cavity 112 with the outside air. Therefore, when it is necessary to install the connector 10 to the mounting surface 20, the exhaust duct 12 can be opened by the sealing member 13 after the slot 111 abuts against the mounting surface 20, and the air in the sealed cavity 112 can be extracted by the suction device 30 to form a negative pressure in the sealed cavity 112, so that the connector body 11 is adsorbed onto the mounting surface 20, realizing the adsorption fixation of the connector 10 on the mounting surface 20, so that it does not need to penetrate the entire mounting surface 20. This is beneficial to reduce the damage to the building structure and reduce the risk of water leakage at the building mounting surface.

[0056] Optionally, such as Figure 3 , Figure 12 As shown, the sealing member 13 is movably installed on the connector body 11 to block or open the exhaust passage 12.

[0057] It should be noted that there are no restrictions on the specific implementation of the movable installation of the sealing component 13. It can be installed by rotation or by movement. For example, when the sealing component 13 is installed on the connector body 11 by rotation, one end of the sealing component 13 can be rotatably connected to the outer edge of the exhaust channel 12. By rotating, the other end of the sealing component 13 moves closer to or away from the outer end of the exhaust channel 12, thereby correspondingly sealing or opening the exhaust channel 12. As another example, when the sealing component 13 is installed on the connector body 11 by movement, the sealing component 13 can be movably installed on the connector body 11 along the axial direction of the exhaust channel 12 to move closer to or away from the outer end of the exhaust channel 12, thereby correspondingly sealing or opening the exhaust channel 12.

[0058] In this embodiment, the movable sealing member 13 allows the user to quickly seal or open the exhaust passage 12 without having to perform cumbersome disassembly and assembly steps on the sealing member, which helps to improve the installation efficiency of this connector 10.

[0059] Optionally, such as Figure 3 As shown, the sealing member 13 includes a cover plate 131 and a first elastic member 132. The cover plate 131 is disposed at the outer end of the exhaust channel 12. The two ends of the first elastic member 132 are respectively connected to the cover plate 131 and the connecting member body 11.

[0060] Specifically, the cover plate 131 is used to block or open the outer end of the exhaust passage 12, and the first elastic member 132 may have a tendency to drive the cover plate 131 to block the outer end of the exhaust passage 12. Alternatively, the first elastic member 132 may be a spring. It is understood that the cover plate 131 can move relative to the connecting body 11 by means of the first elastic member 132. When the cover plate 131 is subjected to an external force and moves away from the outer end of the exhaust passage 12 to open the exhaust passage 12, the first elastic member 132 will undergo elastic deformation during this process. When the external force on the cover plate 131 is released, the deformation restoring force of the first elastic member 132 will drive the cover plate 131 closer to the outer end of the exhaust passage 12 to block the exhaust passage 12.

[0061] In this embodiment, by placing the cover plate 131 at the outer end of the exhaust duct 12, the cover plate 131 can open or close the exhaust duct 12 when it is away from or close to the outer end of the exhaust duct 12. The entire cover plate 131 is independent of the exhaust duct 12. Compared with placing the cover plate 131 inside the exhaust duct 12, the ease of installation of the cover plate 131 can be improved. In addition, when the cover plate 131 is sealed at the outer end of the exhaust duct 12 by the first elastic member 132, the deformation recovery force applied by the first elastic member 132 can make the cover plate 131 stably press against the outer end of the exhaust duct 12, which helps to ensure the sealing of the inside of the connector body 11.

[0062] Optionally, such as Figure 3As shown, the exhaust duct 12 includes a through hole 121 provided in the wall of the connector body 11; the first elastic member 132 passes through the through hole 121, one end of the first elastic member 132 is connected to the cover plate 131, and the other end is fixed inside the connector body 11.

[0063] It is understandable that when the cover plate 131 is subjected to an external force along the axial direction of the exhaust passage 12 and moves away from the outer end of the exhaust passage 12 to open the exhaust passage 12, the cover plate 131 will cause the first elastic element 132 to elongate axially during this process. When the external force on the cover plate 131 is released, the first elastic element 132 will contract axially to move the cover plate 131 closer to the outer end of the exhaust passage 12 until the exhaust passage 12 is blocked. The external force along the axial direction of the exhaust passage 12 applied to the cover plate 131 can be applied by the suction device 30. Specifically, refer to... Figure 4 and Figure 5 The suction pipe 31 of the suction device 30 can be sleeved with the connecting wall 114 of the connector body 11. After the suction device 30 is started, the suction force generated by the suction device 30 can be applied to the cover plate 131 to drive the cover plate 131 away from the outer end of the exhaust channel 12 and open the exhaust channel 12.

[0064] In this embodiment, the exhaust channel 12 is formed by opening a through hole 121 in the wall of the connector body 11, which is simple in structure and helps to reduce the processing difficulty. Furthermore, since the exhaust channel 12 is directly set as a through hole 121, that is, the length of the exhaust channel 12 is approximately equal to the wall thickness of the connector body 11. The wall thickness of the connector body 11 is usually small, so this can ensure that the exhaust channel 12 also has a small length. As a result, there is a small contact surface between the inner wall surface of the exhaust channel 12 and the first elastic member 132, which can improve the smoothness of the extension and retraction of the first elastic member 132. At the same time, since the first elastic member 132 passes through the exhaust channel 12, the extension and retraction of the first elastic member 132 will be limited by the exhaust channel 12, which helps to prevent the first elastic member 132 from deflecting radially along the exhaust channel 12 during extension and retraction, thereby helping to ensure that the cover plate 131 is aligned with the outer end of the exhaust channel 12.

[0065] Optionally, such as Figure 3 As shown, the connector body 11 has a connecting plate 113 inside. The connecting plate 113 is opposite to the exhaust duct 12 and is connected to the inner wall of the connector body 11 through a connecting post 1131. The end of the first elastic member 132 away from the cover plate 131 is connected to the connecting plate 113.

[0066] In this embodiment, the connecting plate 113 and the connecting post 1131 can cooperate to fix the end of the first elastic member 132 inside the connecting body 11. At the same time, the connection plate 113 and the exhaust channel 12 are arranged opposite to each other to ensure that the connecting plate 113 will not block the exhaust channel 12, so as to ensure that the air in the sealed cavity 112 is discharged normally to the exhaust channel 12.

[0067] Optionally, such as Figure 3 and Figure 6 As shown, the cover plate 131 has a pull ring 1311 on the side away from the connector body 11.

[0068] In this embodiment, when an external force is applied to the pull ring 1311 that can overcome the pressure difference between the inside and outside of the sealing cavity 112 and the elastic force of the first elastic member 132, the cover plate 131 can be moved to open the exhaust channel 12. At this time, outside air can automatically flow into the sealing cavity 112 to eliminate the negative pressure in the sealing cavity 112, which facilitates the subsequent disassembly of the connector 10. That is, the presence of the pull ring 1311 can help move the cover plate 131, thereby making it easier to disassemble the connector 10.

[0069] Optionally, such as Figure 3 and Figure 6 As shown, the cover plate 131 has a sealing gasket 1312 on the side near the connector body 11.

[0070] In this embodiment, since a sealing gasket 1312 is provided on the side of the cover plate 131 near the connector body 11, when the first elastic member 132 controls the cover plate 131 to block the exhaust channel 12, the sealing gasket 1312 can be deformed by the pressure of the cover plate 131 and the connector body 11 at the same time, so as to prevent air leakage between the cover plate 131 and the connector body 11, thereby helping to ensure the airtightness of the sealing cavity 112.

[0071] Optionally, such as Figure 1 , Figure 5 As shown, the outer wall of the connector body 11 is provided with a connecting wall 114, which surrounds the exhaust duct 12.

[0072] Specifically, the shape of the connecting wall 114 can be adapted to the shape of the suction pipe 31 of the suction device 30.

[0073] In this embodiment, the connecting wall 114 is arranged around the exhaust duct 12, that is, the connecting wall 114 as a whole can form a ring structure, which facilitates connection with the air extraction pipe 31 of the air intake device 30 and helps to extract air.

[0074] Optionally, such as Figure 12 and Figure 15As shown, the outer end of the exhaust duct 12 has an outer connecting port 1221 that connects to the outside of the connector body 11, and the side wall of the exhaust duct 12 has an inner connecting port 1222 that connects to the slot 111; the sealing member 13 includes a sealing block 133 and a second elastic member 134; the sealing block 133 is movably disposed in the exhaust duct 12 so that the outer connecting port 1221 and the inner connecting port 1222 are connected or disconnected; one end of the second elastic member 134 is connected to the inner end of the exhaust duct 12, and the other end is connected to the sealing block 133.

[0075] Specifically, the periphery of the sealing block 133 can seal against the side wall of the exhaust duct 12, so that air will not leak between the periphery of the sealing block 133 and the side wall of the exhaust duct 12 when the outer connection port 1221 and the inner connection port 1222 are disconnected. It can also be understood that during the movement of the sealing block 133 within the exhaust duct 12, when the sealing block 133 is between the outer connection port 1221 and the inner connection port 1222, air is blocked by the sealing block 133 and cannot flow between them, thus disconnecting the outer connection port 1221 and the inner connection port 1222 to block the exhaust duct 12. When the sealing block 133 is below the inner connection port 1222, air is not blocked by the sealing block 133 and can flow freely between the outer connection port 1221 and the inner connection port 1222, thus connecting the outer connection port 1221 and the inner connection port 1222 to open the exhaust duct 12. The second elastic element 134 may have a tendency to cause the sealing block 133 to disconnect the outer connection port 1221 and the inner connection port 1222. Alternatively, the second elastic element 134 may be a spring. It is also understood that the sealing block 133 can move relative to the connecting body 11 via the second elastic element 134. When the sealing block 133 is moved to a position where the outer connection port 1221 and the inner connection port 1222 are connected by an external force along the axial direction of the exhaust passage 12, thus opening the exhaust passage 12, the second elastic element 134 undergoes elastic deformation. When the external force on the sealing block 133 is released, the deformation restoring force of the second elastic element 134 will drive the sealing block 133 to return to its original position along the axial direction of the exhaust passage 12, thus disconnecting the outer connection port 1221 and the inner connection port 1222, thereby sealing the exhaust passage 12. The external force on the sealing block 133 along the axial direction of the exhaust passage 12 can be applied by the suction device 30. Specifically, refer to... Figure 13 and Figure 14 The air needle 32 of the suction device 30 can be inserted into the exhaust channel 12 through the outer connection port 1221, and the sealing block 133 can be pushed downward through the air needle 32 until the outer connection port 1221 and the inner connection port 1222 are connected.

[0076] In this embodiment, by movably placing the sealing block 133 within the exhaust duct 12, the entire sealing block 133 can be hidden within the exhaust duct 12, thereby avoiding prolonged exposure to sunlight and the resulting erosion from ultraviolet rays, which could lead to aging and failure. In addition, the second elastic member 134 can apply a deformation recovery force to the sealing block 133, enabling the sealing block 133 to reliably disconnect the outer connecting port 1221 and the inner connecting port 1222 to block the exhaust duct 12, which helps to ensure the airtightness of the sealing cavity 112.

[0077] Optionally, such as Figure 12 and Figure 15 As shown, the exhaust duct 12 includes an exhaust column 122 that passes through the wall of the connector body 11.

[0078] Specifically, the sealing block 133 can be installed inside the exhaust column 122, and the second elastic member 134 can be disposed inside the exhaust column 122, with one end connected to the sealing block 133 and the other end connected to the bottom of the exhaust column 122.

[0079] In this embodiment, by setting the exhaust channel 12 as an exhaust column 122 that passes through the wall of the connector body 11, it can have a relatively larger length than setting the exhaust channel 12 as a through hole 121. That is, the exhaust channel 12 is longer, which can provide sufficient extension and retraction space for the second elastic member 134 and play a better guiding role in the extension and retraction stroke of the second elastic member 134.

[0080] Optionally, such as Figure 12 As shown, the connector 10 also includes an air plug 14, which is used to be disposed in the external communication port 1221.

[0081] Specifically, when it is necessary to install the connector 10, the air plug 14 can be removed from the outer connection port 1221, and the air in the sealing cavity 112 can be extracted by the air suction device 30. After the air is extracted, the air plug 14 can be put back into the outer connection port 1221 to seal the outer connection port 1221. When it is necessary to disassemble the connector 10, the air plug 14 can be removed from the outer connection port 1221 so that it can pass through the outer connection port 1221 to push the sealing block 133 to connect the outer connection port 1221 and the inner connection port 1222, so that the sealing cavity 112 can be filled with air.

[0082] In this embodiment, the air plug 14 can be inserted into the outer communication port 1221 after the sealing block 133 disconnects the outer communication port 1221 and the inner communication port 1222, so as to block the outer communication port 1221 and thereby improve the sealing effect on the exhaust passage 12.

[0083] Optionally, such as Figure 3 , Figure 12As shown, a sealant layer 15 is provided around the groove 111, and the groove 111 is sealed to the mounting surface 20 through the sealant layer 15.

[0084] Specifically, the sealant layer 15 can be formed as follows: after placing the connector body 11 on the mounting surface 20, sealant is injected between the groove 111 of the connector body 11 and the mounting surface 20 to form a sealant layer 15 surrounding the groove 111. Specifically, the sealant layer 15 can be made of silicone sealant or polyurethane sealant.

[0085] In this embodiment, the sealing adhesive layer 15 can achieve a sealed connection between the groove 111 and the mounting surface 20, thereby improving the sealing performance of the sealing cavity 112 and ensuring that the sealing cavity 112 is in a relatively stable negative pressure state.

[0086] Optionally, in some other embodiments, the connector 10 further includes anchors that connect the connector body 11 and the mounting surface 20 respectively.

[0087] Specifically, the anchors can be driven into the mounting surface 20 to a shallow depth.

[0088] In this embodiment, the anchor can establish an anchoring connection between the connector body 11 and the mounting surface 20. Combined with the adsorption connection formed by the sealing cavity 112, the fixing effect of the connector 10 on the mounting surface 20 can be relatively improved. At the same time, based on the negative pressure adsorption between the connector body 11 and the mounting surface 20, the anchor can be driven into the mounting surface 20 to a relatively shallow depth, without penetrating the mounting surface 20 and causing water leakage.

[0089] Optionally, such as Figure 7 and Figure 8 , Figure 16 and Figure 17 As shown, the connector body 11 is provided with a hook 16, which is used to connect with the bracket structure 40, and the bracket structure 40 is used to install the photovoltaic module 50.

[0090] Specifically, the hook 16 may include two opposing arms 161 and a connecting arm 162 connected between the two arms 161, one of which may be connected to the connector body 11; the bracket structure 40 may be a connecting beam, which may be bolted to the other arm 161.

[0091] In this embodiment, the connection and fixation between the connector body 11 and the support structure 40 can be achieved by the hook 16, making it difficult for the support structure 40 to detach from the connector 10, thus ensuring the structural stability of the entire photovoltaic system.

[0092] like Figure 9 ,Figure 18 As shown, the present disclosure provides a photovoltaic system including a support structure 40, a photovoltaic module 50 and a connector 10 as described above. The support structure 40 is connected to the connector 10, and the photovoltaic module 50 is mounted on the support structure 40.

[0093] Specifically, the support structure 4 can be connected to the hook 16 of the connector 10.

[0094] In this embodiment, since the photovoltaic system includes the connector 10 described above, it possesses all the beneficial effects of all embodiments of the connector 10 described above, which will not be repeated here.

[0095] While the above disclosure is provided, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of this disclosure.
