Description

Technical Field

[0001] The utility model relates to the technical field of mounting brackets, in particular to a solar combiner box mounting bracket. Background Art

[0002] In the solar photovoltaic power generation system, in order to reduce the connection between the solar photovoltaic cell array and the inverter, a combiner box is used. Today, the combiner box has developed to the third generation, which can not only protect against lightning, but also monitor the current and voltage of each line, and can also detect the temperature and humidity of the combiner box. At present, the sizes of combiner boxes on the market are different. To install the combiner box, a bracket that matches the size of the combiner box is required.

[0003] The existing patent (publication number: CN212137033U) proposes a photovoltaic lightning protection junction box mounting bracket, including an upper mounting frame and a lower mounting frame with a C-shaped cross-section and a scissor structure for adjusting the distance between the upper mounting frame and the lower mounting frame. The upper mounting frame and the lower mounting frame are each provided with two, and strip holes are provided on one side of the mounting frame. Baffles with screw holes are respectively installed at the adjacent inner ends of the two upper mounting frames and the adjacent inner ends of the lower mounting frames. A screw rod that cooperates with the thread thereof is provided between the baffle plates located on the same horizontal plane. The thread directions of the two ends of the screw rod are opposite, and the middle part of the screw rod is mounted on a connecting piece connected to the solar photovoltaic panel mounting assembly.

[0004] The above-mentioned junction box mounting bracket adopts an upper mounting frame and a lower mounting frame with a C-shaped cross-section and a scissor structure for adjusting the distance between the upper mounting frame and the lower mounting frame in the technical solution for installation. When installing junction boxes of different sizes, corresponding proportional adjustments are required, which is time-consuming. In addition, in terms of subsequent maintenance, since the junction box can only be fixed on the mounting bracket, the fixed junction box on the mounting bracket cannot be adjusted to a suitable height for maintenance personnel, which is inconvenient for maintenance. Therefore, we propose a solar junction box mounting bracket to solve the above problems. Utility Model Content

[0005] The utility model provides a solar energy combiner box mounting bracket, which solves the technical problems that the current mounting bracket needs to be adjusted to match the size of the solar energy combiner box and the installation is complicated.

[0011] By adopting the above technical solution: by setting two groups of the first fixing plate, the second fixing plate and the first spring respectively, and coordinating the setting of the adjustment component, the fixation of the solar combiner box has a more stable effect.

[0012] Preferably, gaskets are fixed at both ends of the connecting rod.

[0013] By adopting the above technical solution, gaskets are fixed at both ends of the connecting rod, so that the connection rod and the bearing plate and the pressure plate are fixed more firmly.

[0014] Preferably, the first box and the second box are both provided with a second spring, one end of the second spring in the first box is fixed to the inner wall of the first box, and one end of the second spring away from the inner wall of the first box is fixed to the outside of the second box, one end of the second spring in the second box is fixed to the inner wall of the second box, and one end of the second spring away from the inner wall of the second box is fixed to the outside of the supporting plate.

When fixing the junction box, the second spring will have a rebound tension, thereby further increasing the fastening effect.

[0016] Preferably, a rubber pad is fixed on the pressing plate.

[0017] The above technical solution is adopted: by fixing a rubber pad on the pressing plate, the pressing plate is prevented from directly contacting the combiner box and causing wear of the combiner box. The rubber pad has a good buffering effect.
