Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic brackets, specifically a wind-resistant device for distributed household photovoltaic brackets. Background Technology

[0002] In current distributed residential photovoltaic (PV) systems, the wind-resistant design of the PV mounting system is crucial. Especially in areas prone to typhoons or strong winds, the traditional approach to counteract negative wind suction (i.e., upward wind loads) is to install diagonal bracing at the bottom or diagonal support points of the rooftop PV system. However, this traditional method has significant drawbacks:

[0003] Firstly, the installation of tie rods on the roof will occupy valuable space that could have been used to install photovoltaic modules, reducing the utilization rate of the roof area and thus affecting the power generation efficiency of the entire photovoltaic system.

[0004] Secondly, traditional tie rods mostly use a fixed structure, which means they can only adapt to specific roof slopes or installation conditions. When encountering different situations, it is necessary to customize tie rods of different specifications, which undoubtedly increases installation costs and construction difficulty.

[0005] Third, some existing adjustable rods usually require manual operation and have low adjustment accuracy. They cannot be dynamically adjusted according to the actual wind load, resulting in poor reliability in resisting extreme weather conditions.

[0006] Currently, while existing patent literature proposes some wind-resistant structures, most still rely on roof space, failing to fundamentally solve the problems of space waste and poor applicability. For example... Figure 3 The diagram shown illustrates existing technology. Therefore, developing a wind-resistant device that does not occupy roof space, is flexibly adjustable, and is safe and reliable has become a pressing technical challenge in the field of distributed residential photovoltaic systems. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a wind-resistant device for distributed residential photovoltaic brackets, thereby solving the issues of space waste and poor applicability in the prior art.

[0008] A wind-resistant device for distributed residential photovoltaic (PV) systems includes a PV system, a telescopic back brace, a rear horizontal bar, a rear diagonal brace, and triangular connectors.

[0009] A photovoltaic support system, installed on a roof, includes columns, diagonal braces, diagonal beams, and an upper purlin track. The purlin track is equipped with a locking device for fixing the photovoltaic modules.

[0010] The side fixing assembly includes a rear horizontal bar and a rear diagonal brace. One end of the rear horizontal bar is fixed to the side wall of the house via a triangular connector, and the other end is connected to the rear diagonal brace. One end of the rear diagonal brace is fixed to the wall, and the other end is connected to a telescopic back brace.

[0011] The telescopic back pull rod adopts a sleeve-type multi-stage telescopic structure and has an internal locking mechanism for adjusting and fixing the length of the pull rod;

[0012] The bracket connector is located at the bottom of the photovoltaic bracket or the main beam position, and is connected to the top of the telescopic back tie rod by bolts to realize the force transmission between the photovoltaic bracket and the tie rod.

[0013] Preferably, the locking mechanism of the retractable back lever is one of a spring pin, a bolt locking mechanism, or a hydraulic locking mechanism, used to precisely adjust and fix the length of the lever.

[0014] Preferably, the triangular connector is an adjustable angle connector to accommodate different installation angles between the wall and the photovoltaic bracket.

[0015] Preferably, the rear horizontal bar and rear diagonal brace are fixed to the side wall of the house by expansion bolts or chemical anchors.

[0016] Preferably, the locking device on the purlin track adopts a quick-locking structure, which facilitates the installation and disassembly of photovoltaic modules.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model saves roof space by fixing the tie rod to the side of the house, avoiding the need to install tie rods on the roof, so that the entire roof can be used to install photovoltaic modules, thereby improving the utilization rate of the roof area and the power generation efficiency of the photovoltaic system.

[0019] 2. This utility model adapts to various working conditions: the telescopic tie rod can be flexibly adjusted according to different roof slopes, support heights and local wind loads, expanding the applicability of the device and reducing installation costs and construction difficulties.

[0020] 3. This utility model improves safety: by precisely adjusting the length of the pull rod and adopting a reliable locking mechanism, the device can better resist negative wind suction, thereby improving the safety and stability of the photovoltaic system under severe weather conditions such as strong winds.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] like Figure 1-2 As shown, a wind-resistant device for a distributed residential photovoltaic (PV) bracket includes a PV bracket 1, a telescopic back brace 2, a rear horizontal bar 3, a rear diagonal brace 4, and a triangular connector 5.

[0027] The photovoltaic bracket 1 is installed on the roof and includes columns 6, diagonal braces 7, diagonal beams 8 and upper purlin tracks 9. The purlin tracks 9 are equipped with locking devices for fixing photovoltaic modules. The locking devices on the purlin tracks 9 adopt a quick-clamp structure to facilitate the installation and removal of photovoltaic modules.

[0028] The side fixing assembly includes a rear horizontal bar 3 and a rear diagonal brace 4. One end of the rear horizontal bar 3 is fixed to the side wall of the house via a triangular connector 5, and the other end is connected to the rear diagonal brace 4. The triangular connector 5 is an adjustable angle connector to adapt to different installation angles between the wall and the photovoltaic bracket 1. One end of the rear diagonal brace 4 is fixed to the wall, and the other end is connected to a telescopic back brace 2. The rear horizontal bar 3 and the rear diagonal brace 4 are fixed to the side wall of the house via expansion bolts or chemical anchors.

[0029] The telescopic back pull rod 2 adopts a sleeve-type multi-stage telescopic structure and has an internal locking mechanism for adjusting and fixing the length of the pull rod. The locking mechanism of the telescopic back pull rod 2 is one of spring pin, bolt locking or hydraulic locking structure, which is used to precisely adjust and fix the length of the pull rod.

[0030] The bracket connector is located at the bottom of the photovoltaic bracket 1 or at the main beam position, and is connected to the top of the telescopic back tie rod 2 by bolts to realize the force transmission between the photovoltaic bracket 1 and the tie rod.

[0031] The photovoltaic bracket 1 is used as follows: Install the photovoltaic bracket 1 on the roof and fix the photovoltaic modules using columns 6, diagonal braces 7, and purlin tracks 9; install triangular connectors 5 on the side wall of the building and fix the rear horizontal bar 3 and rear diagonal brace; adjust the length of the telescopic back brace 2 so that one end connects to the bracket connector and the other end connects to the rear diagonal brace 4; fix the telescopic back brace 2 using a locking mechanism. The length of the telescopic back brace 2 is dynamically adjusted according to the roof slope, bracket height, and local wind load to ensure the stability of the photovoltaic bracket 1 under wind load. This solution effectively utilizes the side space of the building by changing the fixed position of the brace, avoiding the occupation of roof area. Simultaneously, the telescopic adjustable brace structure can adapt to various working conditions, improving the wind resistance and overall performance of the photovoltaic system.
