Abstract
Description
[Technical Field]
[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to rooftop photovoltaic power stations. [Background Technology]
[0002] In rooftop photovoltaic power stations, gable roof installation has become the mainstream. Common technical solutions for gable roofs include hook-and-mount schemes and overhead schemes. However, the conventional hook-and-mount scheme requires removing tiles for installation, affecting the original roof structure and posing a significant risk of future leaks, resulting in low acceptance among farmers. The overhead scheme, on the other hand, is more widely accepted. This scheme uses a front-pull, rear-pull structure, requiring triangular bracing on both sides of the roof. An example of a triangular bracing can be found in Chinese Utility Model Patent CN218264616 U, which relates to a photovoltaic installation structure for a sloping roof. The structure includes several steel inclined beams installed on the front sloping surface of a gable roof, several steel back braces on the rear sloping surface of the gable roof, and several photovoltaic panels. Each steel inclined beam corresponds to and is hinged to a steel back brace. The front ends of the steel inclined beams are fixed to the front exterior wall of the building via steel front bracing. Several steel feet are provided between the steel inclined beams and the front sloping surface of the roof. The photovoltaic panels are installed on the steel inclined beams via a crossbeam fixing assembly, and the steel back braces are fixed to the rear sloping surface of the roof via a rear hook device.
[0003] The on-site installation of the triangular bracing is complicated, involves too many parts, and has varying lengths. The on-site construction team also makes significant cutting errors, resulting in non-standard installation of the triangular bracing. This has a major impact on the safety of the overall support structure and the aesthetics of the power station, leading to increased customer complaints and greatly hindering market development. [Utility Model Content]
[0004] To address the shortcomings of existing technologies, the present invention aims to provide an adjustable length and angle bracing device and a rooftop photovoltaic power station, thereby resolving the issues of cumbersome on-site installation and potential for non-standard installation of triangular bracing in existing technologies.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] First, an adjustable length and angle bracing device is provided, which is fixed to the wall and used to support the cantilevered part of the inclined beam. It includes two adjustable length support rods and two adjustable angle supports. The two adjustable angle supports are fixed to the wall and are aligned vertically. The first adjustable length support rod is inclined and one end is hinged to the lower adjustable angle support, and the other end is fixed to the cantilevered part of the inclined beam. The second adjustable length support rod is horizontal and one end is hinged to the upper adjustable angle support, and the other end is provided with a movable connection structure between it and the first adjustable length support rod.
[0007] Preferably, the movable connection structure includes an elongated adjustment hole on the first adjustable length support rod, a fixing hole on the second adjustable length support rod, and a fastener connecting the elongated adjustment hole and the fixing hole.
[0008] Preferably, the fastener is an anchor or a bolt.
[0009] Preferably, the anchor includes a base plate and a fixing post. The fixing post includes a spherical crown at the head end, a conical part in the middle, and a cylindrical part at the tail end. The fixing post passes through a fixing hole and an elongated adjustment hole, and the spherical crown is matched with the elongated adjustment hole for limiting.
[0010] Preferably, the adjustable length support rod includes two fixed rod segments and an adjusting rod segment connecting the two fixed rod segments. The fixed rod segments and the adjusting rod segment are movably connected to adjust the length of the adjustable length support rod and are fixed by fasteners.
[0011] Preferably, the fixed rod segment is provided with an elongated adjustment hole, and the adjustment rod segment is provided with at least two fixing holes, and the elongated adjustment hole and the fixing holes are fixed together by fasteners.
[0012] Preferably, the fastener is an anchor or a bolt.
[0013] Preferably, the adjustable length support rod is made of C steel; and / or, the other end of the first adjustable length support rod is located on the side of the cantilevered portion of the inclined beam and is fixed with bolts.
[0014] Preferably, the adjustable angle support includes an upright plate and a side plate welded perpendicularly to the upright plate. The upright plate is fixed to the wall with expansion bolts, and the side plate is connected to a support shaft, which is connected to an adjustable length support rod.
[0015] In addition, a rooftop photovoltaic power station is also provided, including the aforementioned adjustable length and angle bracing device.
[0016] The present invention adopts the above technical solution and has the following beneficial effects:
[0017] 1. Two adjustable angle supports are fixed to the wall and aligned vertically. The first adjustable length support rod is angled, with one end hinged to the lower adjustable angle support and the other end fixed to the cantilevered part of the inclined beam. The second adjustable length support rod is horizontal, with one end hinged to the upper adjustable angle support and the other end connected to the first adjustable length support rod via a movable connection structure. Therefore, during on-site construction, the two adjustable angle supports are fixed first, and then the first adjustable length support rod is fixed to the cantilevered part of the inclined beam. Taking bolt fixing as an example, the fixing holes of both need to be aligned. The two adjustable length support rods can rotate around the adjustable angle supports to adjust their respective angles. Both adjustable length support rods can also be adjusted in length, and the movable connection structure between them ensures no interference during angle and length adjustments. After adjustment, the fixing holes are aligned, allowing for fixing and also restricting the relative relationship between the two adjustable length support rods, forming a stable triangular bracing structure. Therefore, the triangular bracing device can be prefabricated in the factory, and only the angle and length need to be adjusted on site, which reduces the difficulty of construction, ensures the quality of installation, solves the problems of construction quality and aesthetics, and helps to increase market share.
[0018] 2. The first adjustable length support rod is provided with an elongated adjustment hole, and the second adjustable length support rod is provided with a fixing hole. The elongated adjustment hole and the fixing hole can move relative to each other. A fastener is connected between the elongated adjustment hole and the fixing hole, so the fastener can move along the length direction of the elongated adjustment hole. At the same time, the second length adjustment rod can be adjusted in length and angle.
[0019] 3. The anchor can be quickly fixed. The anchor includes a base plate and a fixing post. The fixing post includes a spherical crown at the head end, a conical part in the middle, and a cylindrical part at the tail end. Therefore, during fixing, the fixing post passes through the fixing hole and the elongated adjustment hole, and the spherical crown is matched with the elongated adjustment hole for limiting. In this way, the two adjustable length support rods are movably connected, and the second adjustable length support rod can move relative to each other, ensuring effective connection of the node, while not affecting on-site adjustment.
[0020] 4. The adjustable length support rod adopts a conventional length adjustment structure, which can be flexibly extended or shortened according to the site. In addition, the adjustable length support rod can be flexibly rotated around the adjustable angle support to meet the site requirements.
[0021] 5. The adjustable angle support is welded as a whole and prefabricated in the factory for easy processing.

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.
[0032] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.
[0033] 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," "front," and "rear," 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.
[0034] 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.
[0035] 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.
[0036] The rooftop photovoltaic power station in this embodiment can be installed on a double-slope roof or a single-slope roof. A photovoltaic bracket and photovoltaic modules are installed on the sloping roof. The photovoltaic bracket has several inclined beams arranged side by side in the horizontal direction. The lower longitudinal end of the inclined beams extends beyond the wall, forming a cantilever. A triangular brace is provided between the cantilever and the wall. The triangular brace is fixed to the wall and is used to support the cantilever of the inclined beam. Triangular braces may be installed on both the front and rear walls.
[0037] In existing technologies, the components of a triangular brace are cut and installed on-site, resulting in cumbersome on-site installation and a high risk of improper installation. To achieve factory prefabrication and convenient on-site installation, such as... Figures 1 to 6 As shown, this embodiment provides an adjustable length and angle bracing device, which is fixed to the wall 5 and used to support the cantilevered portion 1 of the inclined beam. It includes two adjustable length support rods 4 and two adjustable angle supports 3. The two adjustable angle supports 3 are fixed to the wall and aligned vertically. The first adjustable length support rod is inclined, with one end hinged to the lower adjustable angle support and the other end fixed to the cantilevered portion of the inclined beam. The second adjustable length support rod is horizontal, with one end hinged to the upper adjustable angle support and the other end having a movable connection structure with the first adjustable length support rod.
[0038] Therefore, the first adjustable-length support rod is adjustable in length and can be adjusted in angle relative to the lower adjustable-angle support. The second adjustable-length support rod is also adjustable in length and can be adjusted in angle relative to the upper adjustable-angle support. The first and second adjustable-length support rods are connected by a movable structure, allowing them to move relative to each other, thus adjusting their length and rotation angle. During on-site construction, the two adjustable-angle supports are fixed first, and then the first adjustable-length support rod is fixed to the cantilevered portion of the inclined beam. Taking bolt fixing as an example, the fixing holes on the cantilevered portion of the inclined beam and the first adjustable-length support rod are pre-processed. On-site, the fixing holes need to be aligned. The two adjustable-length support rods can rotate around the adjustable-angle supports to adjust their respective angles. Both adjustable-length support rods can also be adjusted in length, and the movable connection structure between them ensures no interference during angle and length adjustments. After adjustment, the fixing holes are aligned, allowing for fixing and also restricting the relative relationship between the two adjustable-length support rods, forming a stable triangular bracing structure. Therefore, the triangular bracing device can be prefabricated in the factory, and only the angle and length need to be adjusted on site, which reduces the difficulty of construction, ensures the quality of installation, solves the problems of construction quality and aesthetics, and helps to increase market share.
[0039] In some embodiments of the movable connection structure, the first adjustable length support rod has an elongated adjustment hole 43, and the second adjustable length support rod has a fixed hole (circular hole). A fastener connects the elongated adjustment hole 43 and the fixed hole. Therefore, the fastener can move along the length of the elongated adjustment hole, and the second length adjustment rod can be adjusted in both length and angle.
[0040] Preferably, the fastener is an anchor. The anchor 2 includes a base plate 21 and a fixing post. The fixing post includes a spherical crown 24 at the head end, a conical portion 23 in the middle, and a cylindrical portion 22 at the tail end. The fixing post passes through a fixing hole and an elongated adjustment hole, and the spherical crown is in a limiting fit with the elongated adjustment hole. Using an anchor allows for quick fixing. During fixing, the fixing post passes through the fixing hole and the elongated adjustment hole, and the spherical crown is in a limiting fit with the elongated adjustment hole. This allows the two adjustable length support rods to be movably connected, and the second adjustable length support rod can move relative to the other, ensuring effective connection of the node without affecting on-site adjustments.
[0041] Of course, fasteners can also be bolts, which can be tightened after adjustment.
[0042] In some embodiments, the adjustable length support rod 4 includes two fixed rod segments 41 and an adjusting rod segment 42 connecting the two fixed rod segments. The fixed rod segments and the adjusting rod segment are movably connected to adjust the length of the adjustable length support rod and are fixed by fasteners. Specifically, the fixed rod segments are provided with elongated adjustment holes, and the adjusting rod segments are provided with at least two fixed holes. The elongated adjustment holes and the fixed holes are fixed by fasteners. The fasteners are anchors or bolts. The fixed rod segments are movably adjusted relative to the adjusting rod segments, and after adjustment, they are fixed by fasteners. The adjustable length support rod can be flexibly extended or shortened according to the site conditions.
[0043] Of course, the length adjustment structure of the adjustable support rod can be replaced by other structures, such as the joint section of two fixed rod segments 41, one of which has an elongated adjustment hole and the other has a fixed hole, and the elongated adjustment hole and the fixed hole are fixed together by fasteners. For example, it can also be a telescopic rod structure.
[0044] Specifically, the adjustable length support rod is made of C-steel, and the other end of the first adjustable length support rod is located on the side of the cantilevered portion of the inclined beam and fixed with bolts. Of course, the other end of the first adjustable length support rod can also be connected to the cantilevered portion of the inclined beam with a hinge.
[0045] Specifically, the adjustable angle support 3 includes a vertical plate 31 and a side plate 32 welded perpendicularly to the vertical plate. The vertical plate is fixed to the wall using expansion bolts 33, and the side plate is connected to a support shaft, which is connected to an adjustable length support rod 4. The adjustable angle support is prefabricated in the factory for easy processing. The adjustable length support rod can be flexibly rotated around the adjustable angle support to meet site requirements.
[0046] 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.
