Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic grounding, and in particular relates to a photovoltaic component conductive buckle. Background Art

[0002] At present, the lightning protection grounding connection method between photovoltaic modules is to use wires and screws to connect adjacent photovoltaic panels in series. Although the holes for fixing the wires are reserved, the vibration generated during the on-site tightening process will cause the photovoltaic modules to shift and be damaged, affecting the power generation quality of the photovoltaic modules. In addition, the use of wires for lightning protection grounding connection between modules will also cause various problems in the fixing process during later maintenance and replacement. Moreover, especially when the height of the north pole is too high, it is necessary to climb a ladder to tighten the screws, which poses a safety risk.

However, since the conductive member is installed and fixed by a crimping mechanism, and the crimping mechanism is locked by screws, not only is the structure complicated, but the installation is also cumbersome. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a pole-type photovoltaic assembly penetrating conductive buckle to solve the problem of complicated lightning protection and grounding installation operation between photovoltaic panels.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solution: the support pole type photovoltaic component penetrates the conductive buckle and is inserted into the gap between two adjacent photovoltaic panels. The conductive buckle includes two rotatably connected penetration pieces and a connecting rod mechanism connected to the two penetration pieces. The lower end of the penetration piece is provided with a penetration part. The penetration parts at the lower ends of the two penetration pieces are driven by the connecting rod mechanism to open outward and respectively pierce the coatings of the two adjacent photovoltaic panels to electrically connect the two adjacent photovoltaic panels.

[0006] Preferably, the connecting rod mechanism includes two movable support rods and a driving rod, one end of the movable support rod is hinged to the head end of the driving rod, and the other end is hinged to the penetration piece; and / or, the conductive buckle is provided with a locking piece for locking the connecting rod mechanism after the penetration portion is opened outward.

[0007] Preferably, the upper parts of the two penetration sheets are rotatably connected via a first pin.

[0008] Preferably, the penetration piece includes a vertical section and an oblique section connected to the upper end of the vertical section, the penetration portion is located at the lower end of the vertical section, the oblique sections of the two penetration pieces intersect and the intersection is connected to the first pin.

[0009] Preferably, the driving rod is provided with a vertically extending limiting groove, and the limiting groove cooperates with the first pin guide.

[0010] Preferably, the locking member is a locking rod that fixes the first pin shaft to the limiting groove.

[0011] Preferably, the penetration portion is a spike disposed on the outer side of the lower end of the penetration piece.

[0012] Preferably, the penetration piece is a sheet metal part, and the penetration portion is formed by bending the lower end of the penetration piece; and / or, a plurality of spikes are arranged in a serrated shape along the width direction of the penetration piece.

[0013] Preferably, the driving rod is hinged to the two movable support rods via a second pin shaft, and the movable support rod is hinged to the penetration piece via a third pin shaft.

[0014] Preferably, the movable support rod and the driving rod are sheet metal parts.

[0015] The utility model adopts the above technical solution, which brings the following beneficial effects:

[0016] 1. The connecting rod mechanism drives the penetration parts at the lower ends of the two penetration pieces to open outward and pierce the coatings of two adjacent photovoltaic panels respectively, so that the two adjacent photovoltaic panels are electrically connected. Therefore, when it is necessary to electrically connect two adjacent photovoltaic panels, it is only necessary to put the conductive buckle into the gap between the two adjacent photovoltaic panels and then operate the connecting rod mechanism. This reduces the steps of loosening and tightening the screws to fix the wires on site, reducing the risks in construction.

[0017] In terms of installation form, the penetrating conductive buckle of the strut-type photovoltaic module can be installed immediately after the single photovoltaic panel is installed side by side continuously, or after the photovoltaic panel is fully installed; in terms of installation method, the penetrating conductive buckle of the strut-type photovoltaic module supports two installation methods: front and back installation. When performing replacement operations at a later stage, it is only necessary to operate the connecting rod mechanism to drive the penetration parts at the lower ends of the two penetration pieces inward and disengage the penetration parts from the photovoltaic panel to achieve the disconnection of the two photovoltaic panels. Therefore, no other auxiliary tools are required, and the installation can be completed with one hand. It is easy to operate, reduces the difficulty of assembly, and facilitates the installation and removal of the conductive buckle. It will not cause vibration during the installation and removal process, which may cause displacement or damage to the photovoltaic panel, thus ensuring that the photovoltaic panel is not damaged and works stably.

[0018] In terms of the quality and duration of power station construction, the pole-type photovoltaic modules that penetrate the conductive buckles will not cause large vibrations or shakes during installation, will not affect the quality of the power station, and can slightly reduce the construction period of the power station.

[0019] The connecting rod mechanism can control the outward opening angle of the penetration parts at the lower ends of the two penetration pieces, so that the penetration conductive buckle of the strut-type photovoltaic assembly can adapt to gaps of various sizes between the two photovoltaic panels, has a good electrical connection effect on the two photovoltaic panels, and has a wide range of applications.

[0020] 2. The connecting rod mechanism includes two movable support rods and a driving rod. One end of the movable support rod is hinged to the head end of the driving rod, and the other end is hinged to the penetration piece. Therefore, the support rod type photovoltaic assembly penetrates the conductive buckle and extends between the two photovoltaic panels under normal conditions, and then applies a downward pressure to the driving rod. Under the action of pressure, the driving rod moves downward and drives the two movable support rods to open, so that the penetration parts at the lower ends of the two penetration pieces open outward, thereby allowing the penetration parts to pierce the coating of the photovoltaic panel frame.

[0021] In addition, the conductive buckle of the support-pole type photovoltaic assembly is provided with a locking piece which locks the connecting rod mechanism after the penetration part is opened outward, thereby maintaining the expanded shape of the two movable support rods and fixing the conductive buckle between two adjacent photovoltaic panels so that it does not fall out, so that the penetration part maintains electrical connection with the photovoltaic panel frame.

[0022] 3. The upper parts of the two penetration pieces are rotatably connected through the first pin shaft, which has a simple structure and ensures flexible rotation between the two penetration pieces.

[0023] 4. The penetration piece includes a vertical section and an oblique section connected to the upper end of the vertical section, wherein the penetration portion is located at the lower end of the vertical section, the oblique sections of the two penetration pieces intersect and the intersection is connected to the first pin shaft, so that, on the one hand, the oblique section can shorten the working stroke and operation time of the connecting rod mechanism, and on the other hand, the setting of the vertical portion is conducive to increasing the bonding force between the penetration portion and the B side of the photovoltaic panel frame.

[0024] 5. The driving rod is provided with a vertically extending limit groove, which cooperates with the first pin shaft guide. In this way, the driving rod is constrained by the first pin shaft and forms a constraint with the two penetration pieces. The driving rod can only move up and down, which is convenient for the operation of the driving rod, making it easier for the operator to push and pull the driving rod up and down, and facilitating the installation and disassembly of the pole-type photovoltaic module penetrating the conductive buckle.

[0025] 6. The locking member is a locking rod that fixes the first pin shaft to the limiting groove. The locking rod can be locked in conjunction with the pin hole to achieve position locking of the driving rod. The structure is simple, the locking is reliable, and the unlocking is convenient.

[0026] 7. The penetration part is a sharp spike arranged on the outer side of the lower end of the penetration piece, which has a better effect on piercing the coating on the surface of the photovoltaic panel, ensuring that the penetration part can always pierce the coating and contact the frame of the photovoltaic panel to achieve electrical connection between the two.

[0027] 8. The penetration piece, movable support rod and driving rod are all sheet metal parts, which can reduce processing and manufacturing costs.

[0028] 9. Several spikes are arranged in a serrated shape along the width direction of the penetration sheet, so that the penetration part can puncture the photovoltaic panel at multiple points, ensuring that the conductive buckle can achieve a stable electrical connection between the two photovoltaic panels.

[0029] 10. Since the upper parts of the two penetration pieces are rotatably connected through the first pin shaft, the driving rod is hinged to the two movable support rods through the second pin shaft, and the movable support rod is hinged to the penetration piece through the third pin shaft, it is convenient to assemble, and when damaged, the components can be replaced separately, reducing the maintenance and replacement costs.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more, unless otherwise clearly defined.

[0040] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0042] In the photovoltaic system of the prior art, at least two photovoltaic panels are arranged side by side. In order to achieve the overall grounding of the photovoltaic system, a conductive member is provided between two adjacent photovoltaic panels to electrically connect the two adjacent photovoltaic panels, and then the entire photovoltaic system can be grounded through one or more grounding members.

[0043] Example:

[0044] like Figures 1 to 4 As shown, the strut-type photovoltaic assembly penetrates the conductive buckle 100 and is inserted into the gap between two adjacent photovoltaic panels 200. The conductive buckle 100 includes two rotatably connected penetration pieces 7 and a connecting rod mechanism connected to the two penetration pieces 7. A penetration portion 8 is provided at the lower end of the penetration piece 7. The penetration portions 8 at the lower ends of the two penetration pieces are driven by the connecting rod mechanism to open outward and pierce the coatings of the two adjacent photovoltaic panels 200 respectively, so that the two adjacent photovoltaic panels 200 are electrically connected.

[0045] Since a plurality of photovoltaic panels are arranged side by side in the photovoltaic panel array, all the photovoltaic panels can be connected in series by inserting strut-type photovoltaic modules into the gaps between all the photovoltaic panels and penetrating the conductive buckles.

[0046] When two adjacent photovoltaic panels need to be electrically connected, just put the conductive buckle into the gap between the two adjacent photovoltaic panels and then operate the connecting rod mechanism. This reduces the steps of loosening and tightening the screws to fix the wires on site and reduces the risks in construction.

[0047] In terms of installation form, the penetrating conductive buckle of the strut-type photovoltaic module can be installed immediately after the single photovoltaic panel is installed side by side continuously, or after the photovoltaic panel is fully installed; in terms of installation method, the penetrating conductive buckle of the strut-type photovoltaic module supports two installation methods: front and back installation. When performing replacement operations at a later stage, it is only necessary to operate the connecting rod mechanism to drive the penetration parts at the lower ends of the two penetration pieces inward and disengage the penetration parts from the photovoltaic panel to achieve the disconnection of the two photovoltaic panels. Therefore, no other auxiliary tools are required, and the installation can be completed with one hand. It is easy to operate, reduces the difficulty of assembly, and facilitates the installation and removal of the conductive buckle. It will not cause vibration during the installation and removal process, which may cause displacement or damage to the photovoltaic panel, thus ensuring that the photovoltaic panel is not damaged and works stably.

[0048] In terms of the quality and duration of power station construction, the pole-type photovoltaic modules that penetrate the conductive buckles will not cause large vibrations or shakes during installation, will not affect the quality of the power station, and can slightly reduce the construction period of the power station.

[0049] The connecting rod mechanism can control the outward opening angle of the penetration parts at the lower ends of the two penetration pieces, so that the penetration conductive buckle of the strut-type photovoltaic assembly can adapt to gaps of various sizes between the two photovoltaic panels, has a good electrical connection effect on the two photovoltaic panels, and has a wide range of applications.

[0050] Specifically, the connecting rod mechanism includes two movable support rods 5 and a driving rod 3, one end of the movable support rod 5 is hinged to the head end of the driving rod, and the other end is hinged to the penetration piece 7. Therefore, the pole-type photovoltaic assembly penetrates the conductive buckle and extends between the two photovoltaic panels in a normal state, and then applies a downward pressure to the driving rod. Under the pressure, the driving rod moves downward and drives the two movable support rods to open, so that the penetration parts at the lower ends of the two penetration pieces open outward, so that the penetration parts pierce the coating of the photovoltaic panel frame.

[0051] In addition, the conductive buckle 100 is provided with a locking piece for locking the connecting rod mechanism after the penetration part is opened outward. After the locking piece is fixed in position, the two movable support rods are also kept in the open state, and the conductive buckle is fixed between two adjacent photovoltaic panels and does not fall out, so that the penetration part is electrically connected to the photovoltaic panel frame.

[0052] The upper parts of the two penetration pieces 7 are connected in rotation by the first pin shaft 1. The structure is simple, and the two penetration pieces are ensured to rotate flexibly. The penetration piece 7 includes a vertical section 71 and an oblique section 72 connected to the upper end of the vertical section. The penetration portion 8 is located at the lower end of the vertical section. The oblique sections of the two penetration pieces intersect and the intersection is connected to the first pin shaft 1. In this way, on the one hand, the oblique section can shorten the working stroke and operation time of the connecting rod mechanism, and on the other hand, the setting of the vertical section is conducive to increasing the bonding force between the penetration portion and the edge B of the photovoltaic panel frame.

[0053] Furthermore, the driving rod 3 is provided with a vertically extending limit groove 2, and the limit groove 2 is guided and matched with the first pin shaft 1. In this way, the driving rod is constrained by the first pin shaft and forms a constraint between the two penetration pieces. The driving rod can only move up and down, which is convenient for operating the driving rod, making it easier for operators to push and pull the driving rod up and down, and facilitating the installation and removal of the pole-type photovoltaic module penetrating the conductive buckle.

[0054] In this embodiment, the locking member is a locking rod 9 that fixes the first pin 1 to the limiting groove. Figure 2 As shown, at this time, the first pin is located at the uppermost position of the limit slot, and the locking rod 9 is located at the lower side of the first pin, forming a lower limit for the first pin, and the upper side wall of the limit slot is used for the upper limit. The first pin cannot move up and down, and the connecting rod mechanism and the penetration piece are kept in this state. In order to fix the position of the locking rod at this time, pin holes can be provided on the left and right sides of the limit slot, and the first pin is inserted into the pin holes, thereby realizing the position locking of the driving rod. The above technical solution is not only simple in structure and reliable in locking, but also convenient for unlocking.

[0055] In order to ensure that the penetration part pierces the coating on the photovoltaic panel frame, the penetration part 8 is a spike disposed on the outer side of the lower end of the penetration piece. Specifically, a plurality of spikes are arranged in a serrated shape along the width direction of the penetration piece. The penetration part can pierce the photovoltaic panel at multiple points to ensure that the conductive buckle can achieve a stable electrical connection between the two photovoltaic panels. The penetration piece 7 is a sheet metal part, and the penetration part 8 is formed by bending the lower end of the penetration piece. In addition, the movable support rod 5 and the driving rod 3 are also sheet metal parts. This can reduce the processing and manufacturing costs.

[0056] Furthermore, the driving rod 3 is hinged to two movable support rods 5 through a second pin shaft 4, and the movable support rod 5 is hinged to a penetration piece 7 through a third pin shaft 6. The above technical solution is not only convenient for assembly, but also allows components to be replaced individually when damaged, thereby reducing the cost of repair and replacement.

[0057] It is understandable that, in order to prevent the penetration portion 8 from being separated from the edge B 201 of the frame of the photovoltaic panel, the edge B 201 of the frame of the photovoltaic panel may be provided with a recess, and the penetration portion cooperates with the recess.

[0058] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
