Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel installation, in particular to a connection structure for installing rooftop photovoltaic panels. Background Art

[0002] Photovoltaic panels are devices that generate direct current (DC) electricity when exposed to sunlight. They are composed almost entirely of thin, solid-state photovoltaic cells made from semiconductor materials such as silicon. Installing a photovoltaic panel on a roof not only generates electricity for the home but also serves as a roof to block rainwater.

[0003] Chinese patent publication number CN219509014U discloses a rooftop photovoltaic panel, comprising a support frame placed on the roof, multiple groups of photovoltaic panels placed above the support frame, and several connecting plates placed at the edge of the roof. The photovoltaic panels and connecting plates are connected to the support frame via connectors. Each group of photovoltaic panels is parallel to the roof ridge. Multiple groups of photovoltaic panels are staggered and spliced ​​perpendicular to the roof ridge to cover the entire roof. The photovoltaic panels of two adjacent groups are placed on top of the group away from the roof ridge, partially overlapping. This application has the effect of reducing the construction cost of rooftop photovoltaic panels while ensuring normal operation of the panels.

[0004] Regarding the related technologies mentioned above, in the existing technology, the operator uses the cooperation of blocking blocks, connecting bolts and screw columns to achieve the installation of photovoltaic panels. However, in order to limit the photovoltaic panels by screw columns, holes need to be processed on the photovoltaic panels in advance, which increases the processing steps of the photovoltaic panels. The photovoltaic panels need to be clamped during processing, and there is a possibility of damage to the photovoltaic panels. In addition, during the rainy season, rainwater can easily penetrate into the house through the gap between the holes on the photovoltaic panels and the screw columns. Utility Model Content

[0005] In order to solve the above problems, the present application provides a connection structure for installing rooftop photovoltaic panels.

[0006] This application provides a connection structure for rooftop photovoltaic panel installation using the following technical solutions:

[0007] The foldable panel is mounted on a vertical cam portion and has a first end fixed to the top of the panel and a second end fixed to the top of the panel, the second end of the panel being mounted on the cam portion.

[0008] By adopting the above technical solution, when installing photovoltaic panels, the operator first installs several purlins on the roof, then uses the installation assembly to limit the support seat, then inserts a corner of the photovoltaic panel into the first limiting groove, and uses the connecting assembly to install the connecting seat between the two support seats, and then places a corner of the photovoltaic panel into the limiting area to limit the photovoltaic panel. Then, one corner of the adjacent photovoltaic panel is placed into the second limiting groove, and the other corners of the adjacent photovoltaic panels are installed in the same way as above, achieving the purpose of stacking two adjacent photovoltaic panels. Finally, the gap between the two photovoltaic panels is filled by the water blocking member to achieve the installation of the photovoltaic panels. The operator uses the cooperation of the first limiting groove, the second limiting groove and the limiting area to limit the photovoltaic panels and form a stacked installation of two adjacent photovoltaic panels. At the same time, the gap between the two photovoltaic panels is filled by the water blocking member. Compared with the existing technology, the number of punching steps for the photovoltaic panels is reduced, the processing cycle of the photovoltaic panels is shortened, and the possibility of damage to the photovoltaic panels is reduced. During the rainy season, rainwater flows from high to low along the surface of the photovoltaic panels, reducing the possibility of rainwater penetrating into the house and improving the installation efficiency and waterproof performance of the photovoltaic panels.

[0009] Optionally, the connecting assembly includes a support plate, a connecting hook and a resistance plate, one end of the support plate is connected to the connecting seat, the connecting hook is connected to the other end of the support plate, an avoidance groove is provided on the support seat, a snap-fit ​​groove is provided on the groove wall of the avoidance groove close to the connecting seat, the connecting hook snaps into engagement with the snap-fit ​​groove, and the resistance plate is connected to two pieces on the connecting seat, and the two resistance plates are arranged in a V shape. When installing the photovoltaic panel, the resistance plate fits against the baffle on the other support seat, and a first gap is left between a corner of the photovoltaic panel and the groove wall of the first limiting groove, and the first gap is consistent with the distance of the snap-fitting part of the connecting hook.

[0010] By adopting the above technical solution, when installing the connecting seat, the operator passes the connecting hook through the avoidance groove of one support seat, places the connecting seat on the other support seat, and then moves the connecting seat so that the connecting hook is engaged with the engaging groove. At this time, the contact plate fits the baffle on the other support seat. Since the height of the connecting hook is higher than the height of the connecting seat, the freedom of the connecting seat is limited, thereby realizing the installation of the connecting seat.

[0011] Optionally, the connecting assembly also includes a limiting hook. When the photovoltaic panel is installed, a second gap is left between the photovoltaic panel and the inner top wall of the first limiting groove. The second gap is consistent with the thickness of the limiting hook. The limiting hook is located between the photovoltaic panel and the top wall of the first limiting groove, and between the two contact plates.

[0012] By adopting this technical solution, the contact plate only fits the baffle, which can cause the connector to vibrate due to wind, affecting the stability of the photovoltaic panel installation. The staff used a restraining hook inserted between the step frame on the other support and the photovoltaic panel to further restrain the connector, improving the stability of the photovoltaic panel corner and reducing the possibility of vibration.

[0013] Optionally, a first drainage gap is provided between the two step frames, and a second drainage gap is provided between the two limiting plates.

[0014] By adopting the above technical solution, the operator uses the cooperation of the first drainage gap and the second drainage gap to reduce the possibility of rainwater being retained at the corners of the photovoltaic panel, further reducing the leakage of the photovoltaic panel.

[0015] Optionally, the mounting assembly includes a mounting hook plate and a tightening protrusion, the mounting hook plate is L-shaped and is integrally formed with the support seat, the tightening protrusion is integrally formed on the mounting hook plate, and when the support seat is installed, the purlin is located between the tightening protrusion, the mounting hook plate and the mounting seat.

[0016] By adopting the above technical solution, when installing the support seat, the operator will press the pressing protrusion against the purlin, causing the pressing protrusion to deform until the purlin fits the installation hook plate and the bottom wall of the support seat. At this time, the pressing protrusion is restored and presses against the side wall of the purlin, achieving the effect of restricting the support seat on the purlin.

[0017] Optionally, a rib is connected to the limiting plate, and when the photovoltaic panel is installed, a corner of the photovoltaic panel is located between the limiting plate, the rib and the connecting seat.

[0018] By adopting this technical solution, a corner of the photovoltaic panel is located within the restricted area. During the rainy season, this corner of the photovoltaic panel is easily shaken by wind, and rainwater can easily penetrate the water barrier and cause leakage. The operator uses the rib to restrain the corner of the photovoltaic panel, further improving the stability of the photovoltaic panel installation and reducing the possibility of rainwater seeping through the edge of the photovoltaic panel.

[0019] Optionally, a pad is connected to the inner top wall of the support seat, and the thickness of the pad is consistent with the second gap.

[0020] By adopting the above technical solution, the spacer is used to fill the second gap, further improving the stability of the photovoltaic panel located in the corner of the first limiting groove, and further improving the installation stability of the photovoltaic panel.

[0021] Optionally, the water blocking member is a waterproof strip, and the water blocking member is sleeved on the side of one photovoltaic panel and fits against the side wall of another photovoltaic panel.

[0022] By adopting the above technical solution, when installing the water-blocking component, the operator puts the water-blocking component on the side of the photovoltaic panel, and then uses the side wall of the water-blocking component to fit the bottom wall of another photovoltaic panel to block the gap between the two photovoltaic panels, thereby reducing the possibility of rainwater leaking between the photovoltaic panels.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When installing photovoltaic panels, the operator first installs several purlins on the roof, and then uses the installation assembly to limit the support seat, and then inserts a corner of the photovoltaic panel into the first limiting groove, and at the same time uses the connection assembly to install the connection seat between the two support seats, and then places a corner of the photovoltaic panel into the limiting area to limit the photovoltaic panel, and then places a corner of the adjacent photovoltaic panel into the second limiting groove, and the other corners of the adjacent photovoltaic panels are installed in the same way as above, achieving the purpose of stacking two adjacent photovoltaic panels, and finally using the water-blocking member to fill the gap between the two photovoltaic panels to achieve the installation of the photovoltaic panels. The operator uses the cooperation of the first limiting groove, the second limiting groove and the limiting area to limit the photovoltaic panel, and form a stacked installation of two adjacent photovoltaic panels, and at the same time uses the water-blocking member to fill the gap between the two photovoltaic panels. Compared with the existing technology, the number of punching steps for the photovoltaic panels is reduced, the processing cycle of the photovoltaic panels is shortened, and the possibility of damage to the photovoltaic panels is reduced. During the rainy season, rainwater flows from high to low along the surface of the photovoltaic panel, reducing the possibility of rainwater penetrating into the house, and improving the installation efficiency and waterproof performance of the photovoltaic panels;

[0025] 2. When installing the connecting seat, the operator passes the connecting hook through the avoidance groove of one support seat, places the connecting seat on the other support seat, and then moves the connecting seat so that the connecting hook is engaged with the engaging groove.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-Figure 7 This application is described in further detail.

[0035] The embodiment of the present application discloses a connection structure for installing rooftop photovoltaic panels. Figure 1 and Figure 2The connection structure for installing photovoltaic panels on the roof includes a support base 1, a connection base 2 and a purlin 3. The purlin 3 is connected by bolts between the two sides of the roof.

[0036] Reference Figure 2 The support base 1 is placed on the purlin 3. Step frames 11 are fixedly connected to the adjacent two sides of the support base 1. A first drainage gap 12 is provided between the two step frames 11. A first limiting groove 112 is formed between the step frame 11 and the support base 1. A baffle 111 is integrally formed on the step frame 11, and a second limiting groove 113 is formed between the baffle 111 and the step frame 11.

[0037] Reference Figure 3 The support base 1 is provided with a mounting assembly 4, which includes a mounting hook plate 41 and a tightening convex plate 42. The mounting hook plate 41 is L-shaped and is integrally formed with the support base 1. The tightening convex plate 42 is integrally formed on the mounting hook plate 41.

[0038] When installing the support seat 1, the operator puts the support seat 1 on the purlin 3. During this process, the purlin 3 contacts the installation hook plate 41, and the installation hook plate 41 is deformed until the purlin 3 fits between the installation hook plate 41 and the support seat 1. At this time, the pressing convex plate 42 is restored and pressed against the side wall of the purlin 3, thereby limiting the freedom of the support seat 1 and realizing the installation of the support seat 1.

[0039] Reference Figure 2 The connecting base 2 is placed between the two supporting bases 1. Restriction plates 21 are integrally formed on both adjacent sides of the connecting base 2. A second drainage gap 22 is provided between the two restriction plates 21. A retaining edge 211 is fixedly connected to each of the restriction plates 21. The retaining edge 211 is used to further stabilize a corner of the photovoltaic panel 01. A restricted area is formed between the two restriction plates 21 and the connecting base 2.

[0040] Reference Figure 4 、 Figure 5 and Figure 6 The connection base 2 is provided with a connection assembly 5, which includes a support plate 51, a connection hook 52, a contact plate 53, and a limiting hook 54. One end of the support plate 51 is integrally formed with the connection base 2, and the connection hook 52 is integrally formed with the other end of the support plate 51. The support base 1 is provided with an avoidance groove, and a snap-fit ​​groove is provided on the side wall of the avoidance groove near the connection base 2, and the connection hook 52 snaps into the snap-fit ​​groove. A first gap 13 is left between the inner side wall of the first limiting groove 112 and the photovoltaic panel 01, and the first gap 13 is at the same distance as the snap-fit ​​part of the connection hook 52.

[0041] Reference Figure 3 、 Figure 4 and Figure 5The two contact plates 53 are integrally formed on the connecting base 2, forming a V-shape. The contact plates 53 engage the baffle 111 of the other supporting base 1. A second gap 14 is left between the inner top wall of the first limiting groove 112 and the photovoltaic panel 01. The limiting hook 54 is integrally formed on the connecting base 2, and the second gap 14 matches the thickness of the limiting hook 54. On the roof, the height of the supporting base 1 at the location of the connecting hook 52 is higher than that at the location of the connecting base 2.

[0042] When installing the connecting seat 2, the operator places the connecting hook 52 into the avoidance groove and pushes the connecting seat 2. The connecting hook 52 is snap-fitted into the snap-fit ​​groove, and the resistance plate 53 fits the baffle 111. At the same time, the restricting hook 54 enters the first restricting groove 112. In this way, the degree of freedom of the connecting seat 2 is limited by the force of gravity, thereby realizing the installation of the connecting seat 2.

[0043] Reference Figure 5 and Figure 6 In order to further improve the stability of the installation of the photovoltaic panel 01, a pad 114 is fixedly connected to the inner top wall of the step frame 11. The thickness of the pad 114 is consistent with the second gap 14. The pad 114 is used to fill the second gap 14, reducing the possibility of shaking of the photovoltaic panel 01.

[0044] Reference Figure 7 The photovoltaic panel 01 is provided with a water blocking member 6, which is a waterproof strip. The water blocking member 6 is sleeved on the photovoltaic panel 01 below and fits the side wall of the photovoltaic panel 01 above.

[0045] The implementation principle of the connection structure for installing rooftop photovoltaic panels in the embodiment of the present application is as follows: when installing the photovoltaic panel 01, the operator sets the support seat 1 on the purlin 3. During this process, the purlin 3 contacts the installation hook plate 41, and the installation hook plate 41 is deformed until the purlin 3 fits between the installation hook plate 41 and the support seat 1. At this time, the convex plate 42 is pressed to recover and press the side wall of the purlin 3 to install the support seat 1. Then, one corner of the photovoltaic panel 01 is inserted into the restricted area, and then the other corner is inserted into the first restricted groove 112. At the same time, the connecting hook 52 is placed in the avoidance groove, and the connecting seat 2 is placed On another support seat 1, the photovoltaic panel 01 and the connecting seat 2 are then moved so that the connecting hook 52 is snap-fitted into the snap-fit ​​groove, the limiting hook 54 is inserted into the first limiting groove 112 of the other support seat 1, and the resistance plate 53 is fitted with the baffle 111 to install a photovoltaic panel 01. Then, while installing other photovoltaic panels 01 in the above manner, the water-blocking component 6 is placed on the side of the other photovoltaic panel 01, and a corner of the other photovoltaic panel 01 is placed in the second limiting groove 113. At this time, the water-blocking component 6 of the lower photovoltaic panel 01 is fitted into the side wall of the upper photovoltaic panel 01, thereby realizing the installation of the photovoltaic panel 01 on the roof.

[0046] The operator utilizes the coordination of first and second limiting grooves 112, 113, and the restricted area to constrain photovoltaic panels 01, forming a stacked installation of two adjacent panels 01. Water-blocking member 6 also fills the gap between the two panels 01. Compared to existing techniques, this reduces the number of drilling steps required for photovoltaic panels 01, shortens the processing cycle, and reduces the risk of damage to panels 01. During the rainy season, rainwater flows from high to low levels along the surface of photovoltaic panels 01, reducing the possibility of rainwater penetrating into the house and improving the installation efficiency and waterproof performance of photovoltaic panels 01.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
