Description

[Technical Field]

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to photovoltaic brackets. [Background Technology]

[0002] With rapid urbanization, installing solar photovoltaic power generation systems on building rooftops and in courtyards has become a trend to alleviate the energy and climate crisis and achieve green building development. However, the wind field environment on building rooftops and in courtyards is complex, with chaotic wind direction and speed. Furthermore, under severe conditions such as blizzards in winter and spring in mid-to-high latitude regions and typhoons in summer and autumn in mid-to-low latitude regions, photovoltaic systems are prone to damage to their supports and connectors, seriously threatening the lives and property of residents.

[0003] Of course, existing technologies also have structures to strengthen photovoltaic supports, such as reinforcing struts between the top of the columns and the inclined beams, or reinforcing structures between the columns, but these reinforcement structures are relatively simple. As the coverage area of ​​photovoltaic supports becomes larger and larger, the column matrix becomes larger and larger, and the number of columns increases exponentially, making it difficult for the original reinforcing structures between the columns to withstand harsh conditions. [Utility Model Content]

[0004] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a reinforced photovoltaic support structure, which adopts a composite reinforcement structure to enhance the support capacity of the photovoltaic support structure so that it can resist harsh weather conditions.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A reinforced photovoltaic support includes at least two columns arranged side by side in the transverse direction, an inclined beam fixed to the top of each column, and a crossbeam perpendicularly fixed to the inclined beam. Photovoltaic panels are installed on the crossbeam. A first reinforcement structure is provided between adjacent columns, and a second reinforcement structure is provided between the top of the column and the inclined beam. The first reinforcement structure includes a transverse reinforcement structure connecting two adjacent columns in the transverse direction and a longitudinal reinforcement structure connecting two adjacent columns in the longitudinal direction.

[0007] Preferably, the lateral reinforcement structure includes a lateral reinforcing horizontal strut connected vertically to the column and / or a lateral reinforcing diagonal strut connected obliquely to the column.

[0008] Preferably, the longitudinal reinforcement structure includes a longitudinally reinforcing horizontal strut that is vertically connected to the column and / or a longitudinally reinforcing diagonal strut that is obliquely connected to the column.

[0009] Preferably, the second reinforcement structure includes a top reinforcing diagonal brace connecting the column and the inclined beam.

[0010] Preferably, the first and second reinforcement structures include a rear tie rod connector fixed to the column, and a reinforcing strut connecting the rear tie rod connector.

[0011] Preferably, the rear tie rod connector consists of two halves that are joined together on the column and fixed by clamp bolts, and the clamp bolts are connected to the reinforcing strut.

[0012] Preferably, a first hinge is provided between the inclined beam and the column, the first hinge is hinged to the column by a first fixing bolt, and the first hinge is fixed to the inclined beam by the first fixing bolt.

[0013] Preferably, the inclined beam is composed of at least two sections of first C-steel spliced ​​together, with an inclined beam connector between adjacent sections of first C-steel. The inclined beam connector is a U-steel, and the bottom wall and one side wall of the inclined beam connector are connected to the first C-steel by inclined beam fixing bolts; and / or, the crossbeam is composed of at least two sections of second C-steel spliced ​​together, with a crossbeam connector between adjacent sections of second C-steel. The crossbeam connector is a U-steel, and the bottom wall of the crossbeam connector is connected to the second C-steel by crossbeam fixing bolts.

[0014] Preferably, a waterproof structure is provided at the gap between two adjacent photovoltaic panels, and the waterproof structure includes a waterproof adhesive strip.

[0015] Preferably, the waterproof strip is located in the lower middle part of the gap between two adjacent photovoltaic panels, and the waterproof structure also includes waterproof adhesive located above the waterproof strip.

[0016] The present invention adopts the above technical solution and has the following beneficial effects:

[0017] 1. Because a first reinforcing structure is provided between the columns, and a second reinforcing structure is provided between the top of the column and the inclined beam, the middle and lower part and the top of the column are reinforced. The first reinforcing structure includes a transverse reinforcing structure connecting two horizontal columns and a longitudinal reinforcing structure connecting two vertical columns. Therefore, both the transverse and longitudinal aspects of the column are reinforced. The above-mentioned composite reinforcing structure greatly enhances the stability and robustness of the photovoltaic support.

[0018] 2. Whether it is a horizontal or vertical reinforcement structure, reinforcing diagonal braces or reinforcing horizontal braces can be used alone, or they can be used in combination. In particular, the reinforcement effect of using them in combination is better, thus greatly enhancing the stability and robustness of the photovoltaic support.

[0019] 3. The second reinforcement structure includes a top reinforcing diagonal brace connecting the column and the inclined beam. The column can be reinforced on one side or on both sides using double-sided reinforcing diagonal braces, thereby forming a stable triangular support and increasing stability.

[0020] 4. The first and second reinforcement structures include a rear tie rod connector fixed to the column, and a reinforcing strut connecting the rear tie rod connector. The reinforcing struts are the aforementioned horizontal reinforcing struts, horizontal reinforcing diagonal struts, longitudinal reinforcing horizontal struts, and longitudinal reinforcing diagonal struts. The rear tie rod connector consists of two halves that are combined and attached to the column and fixed with clamp bolts, which facilitates installation on the column. The reinforcing struts can be connected to the rear tie rod connectors via clamp bolts, which can connect to both horizontal and diagonal struts. This standardization reduces costs and facilitates on-site installation.

[0021] 5. Both inclined beams and horizontal beams use standard steel sections to reduce costs. They can also be lengthened according to actual needs. Two standard steel sections can be connected using universal connectors, which facilitates construction.

[0022] 6. A waterproof structure is provided at the gap between two adjacent photovoltaic panels. The waterproof structure includes not only waterproof strips, but also waterproof adhesive on top of the waterproof strips, thus ensuring reliable waterproofing.

Detailed Implementation Methods

[0041] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0042] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0043] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "longitudinal," and "lateral," which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0046] Reference Figures 1 to 10 As shown, this embodiment provides a reinforced photovoltaic support, including at least two columns 8 arranged in parallel along the horizontal direction, a diagonal beam 1 fixed to the top of each column, and a crossbeam 5 vertically and intersectingly fixed to the diagonal beam. The photovoltaic panel 26 is installed on the crossbeam 5 using a pressure block assembly. The above structure can refer to the prior art.

[0047] This embodiment aims to enhance the support capacity of the photovoltaic support structure, enabling it to withstand harsh weather conditions. A first reinforcing structure is provided between two adjacent columns, and a second reinforcing structure is provided between the top of the column and the inclined beam.

[0048] In this way, the lower middle and top parts of the columns are reinforced. The first reinforcement structure makes the structure between the columns more stable, while the second reinforcement structure directly increases the support for the inclined beam, thus greatly enhancing the stability and robustness of the photovoltaic support system.

[0049] like Figure 1 and Figures 2a to 2cAs shown, in some embodiments, the first reinforcing structure includes a lateral reinforcing structure connecting two horizontally adjacent columns and a longitudinal reinforcing structure connecting two vertically adjacent columns. Therefore, both the lateral and longitudinal aspects of the columns are reinforced, greatly enhancing the stability and robustness of the photovoltaic support. Of course, it is understood that lateral reinforcing structures can be provided between all horizontally adjacent columns and between all vertically adjacent columns; alternatively, lateral reinforcing structures may not be provided between all horizontally adjacent columns, but rather at intervals between columns, or only between some horizontally adjacent columns. Similarly, lateral reinforcing structures may not be provided between all vertically adjacent columns, but rather at intervals between columns, or only between some vertically adjacent columns.

[0050] Specifically, the lateral reinforcement structure includes a horizontal reinforcing strut 16 perpendicularly connected to the column and a horizontal reinforcing diagonal strut 12 diagonally connected to the column. Alternatively, either the horizontal reinforcing strut 16 or the horizontal reinforcing diagonal strut 12 can be installed alone between two columns, or both can be installed simultaneously. The longitudinal reinforcement structure includes a vertical reinforcing strut 11 perpendicularly connected to the column and a longitudinal reinforcing diagonal strut 15 diagonally connected to the column. Similarly, either the longitudinal reinforcing strut 11 or the longitudinal reinforcing diagonal strut 15 can be installed alone between two columns, or both can be installed simultaneously. Therefore, both the lateral and longitudinal directions of the column are reinforced, and this composite reinforcement structure significantly enhances the stability and robustness of the photovoltaic support system.

[0051] like Figure 1 As shown, in this embodiment, the second reinforcement structure includes a top reinforcing diagonal brace 4 connecting the column and the inclined beam. Furthermore, for the rearmost and middle longitudinal columns, the top reinforcing diagonal brace 4 can be connected to both sides of the column in the longitudinal direction; for the frontmost longitudinal column, the top reinforcing diagonal brace 4 is only connected to the front side of that column. Therefore, reinforcement can be applied to one side of the column, or double-sided reinforcement can be used to form a stable triangular support, increasing stability.

[0052] like Figure 5 and Figure 6As shown, the first and second reinforcement structures include a rear tie rod connector 10 fixed to the column, and a reinforcing strut connecting the rear tie rod connector. This reinforcing strut can be one of the aforementioned horizontal reinforcing struts 16, horizontal reinforcing diagonal struts 12, longitudinal reinforcing horizontal struts 11, longitudinal reinforcing diagonal struts 15, or top reinforcing diagonal struts 4. The rear tie rod connector 10 consists of two halves that are joined to the column and fixed by clamp bolts 9, facilitating installation on the column. The clamp bolt on the side connected to the reinforcing strut is connected to the reinforcing strut. It can connect to either the aforementioned horizontal struts or the aforementioned diagonal struts, reducing costs through standardization and facilitating on-site installation. The rear tie rod connector 10 can be fixed to the column by clamp bolts after the column position is determined, and simultaneously connected to the reinforcing strut, without requiring additional fasteners for connection.

[0053] like Figure 4 As shown, a first hinge 7 is provided between the inclined beam 1 and the column 8. The first hinge 7 is hinged to the column 8 by a first fixing bolt 6, and the first hinge 7 is fixed to the inclined beam 1 by the first fixing bolt 6. The connection structure of the first hinge between the inclined beam and the column is similar. Figure 3 As shown, a second hinge 3 is provided between the top reinforcing diagonal brace 4 and the inclined beam 1. The second hinge 3 is hinged to the top reinforcing diagonal brace 4 by the second fixing bolt 2 and fixed to the inclined beam 1 by the second fixing bolt 2.

[0054] like Figure 7a and Figure 7b As shown, the transverse reinforcing horizontal strut 16 is composed of at least two sections of third C-steel 17 spliced ​​together. A cross brace connector 18 is provided between two adjacent sections of third C-steel 17. The cross brace connector 18 is a U-steel, and its bottom wall is connected to the third C-steel 17 by cross brace fixing bolts 19. Of course, the transverse reinforcing diagonal strut 12, the longitudinal reinforcing horizontal strut 11, and the longitudinal reinforcing diagonal strut 15 can also be spliced ​​together using a similar structure.

[0055] like Figure 8a and Figure 8b As shown, the crossbeam 5 is composed of at least two sections of second C steel 20 spliced ​​together. A crossbeam connector 21 is provided between two adjacent sections of second C steel 20. The crossbeam connector 21 is a U-shaped steel. The bottom wall of the crossbeam connector is connected to the second C steel by crossbeam fixing bolts 22.

[0056] like Figure 9a and Figure 9b As shown, the inclined beam 1 is composed of at least two sections of first C steel 23 spliced ​​together. An inclined beam connector 25 is provided between two adjacent sections of first C steel 23. The inclined beam connector is a U steel. The bottom wall and one side wall of the inclined beam connector are connected to the first C steel 23 by inclined beam fixing bolts 24.

[0057] The above technical solutions, whether for inclined beams, horizontal beams, or transverse reinforcing horizontal struts, all use standard steel sections to reduce costs. Moreover, they can be lengthened according to actual needs, and two sections of standard steel sections can be connected using universal connectors, which facilitates construction.

[0058] like Figure 10 As shown, in this embodiment, a waterproof structure is provided at the gap between two adjacent photovoltaic panels. Specifically, the waterproof structure includes a waterproof adhesive strip 28. Furthermore, the waterproof adhesive strip 28 is located in the lower middle part of the gap between two adjacent photovoltaic panels. The waterproof structure also includes waterproof adhesive 27 located above the waterproof adhesive strip, and the waterproof adhesive has a water-guiding groove. The waterproof adhesive strip can be a silicone strip, and the waterproof adhesive is applied on top of the waterproof adhesive strip later, thus ensuring reliable waterproofing through the composite waterproof structure.

[0059] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
