Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power supply boxes, and in particular to a photovoltaic power supply box and a method for using the same. Background Art

[0002] A photovoltaic power box is a distribution device that integrates photovoltaic power into the power grid. Photovoltaic panels are installed on the box of the photovoltaic power box. The photovoltaic panels can convert sunlight energy into electrical energy. The electricity generated by the photovoltaic panels can be stored in batteries to meet outdoor electricity needs.

[0003] Chinese patent publication number CN220754684U discloses a photovoltaic power supply box, comprising a main box body, a power supply box body installed inside the main box body, and an electrically controlled telescopic rod installed inside the power supply box body.

[0004] Although the photovoltaic power box described in the above patent can prevent the photovoltaic panels from being damaged by collisions by setting elastic protective layer 2 and elastic protective layer 1 when in use, the push rod of the photovoltaic power box with the above structure is fixed to the side wall outside the main box body when in use. When the photovoltaic power box is not in use, the push rod cannot be retracted into the main box body, causing the photovoltaic power box to take up too much space when not in use. At the same time, although the electric telescopic rod can drive photovoltaic panel 1 and photovoltaic panel 2 to rise from the main box body when the photovoltaic power box with the above structure is in use, photovoltaic panel 1 and photovoltaic panel 2 are exposed outside the main box body when in use. After long-term use, fallen leaves and dust will fall on the surface of the photovoltaic panels, which will affect the power generation efficiency of the photovoltaic panels.

[0012] Furthermore, the limiting grooves are formed on both side walls of the protective box, the limiting blocks are slidably connected to the limiting grooves, and a collection frame is connected below one side wall of the protective box.

[0013] By adopting the above technical solution, the limiting groove cooperates with the limiting block, which can prevent the cleaning plate from rotating together when the adjusting screw is turned, thereby ensuring that the cleaning plate moves horizontally in the protective box.

[0018] Furthermore, the protective box is bolted to the power box body, an electric telescopic rod is symmetrically installed on the top of the power box body, a control device is provided on the top of the power box body, and the telescopic part of the electric telescopic rod is connected to a photovoltaic panel.

[0019] By adopting the above technical solution, the power box can more firmly fix the electric telescopic rod, and the electric telescopic rod can more easily drive the photovoltaic panel 1 and the photovoltaic panel 2 to rise from the protective box.

[0023] By adopting the above technical solution, the photovoltaic panel 1 and the photovoltaic panel 2 can fix the sliding sleeve more firmly, and the sliding sleeve cooperates with the plug plate to facilitate the photovoltaic panel 2 to be stably aligned with the photovoltaic panel 1.

[0024] The beneficial effects of the present invention are:

[0025] 1. In order to solve the problem that the push rod of the existing photovoltaic power box is fixed to the side wall of the main box body when in use, and the push rod cannot be retracted into the main box body when the photovoltaic power box is not in use, resulting in the photovoltaic power box taking up too much space when not in use, the present invention symmetrically arranges a limiting cylinder on one side wall of the box cover when in use. When the photovoltaic power box is not in use, the limiting bolt is twisted to separate it from the limiting hole on the connecting rod, thereby canceling the limit of the limiting cylinder on the connecting rod, making it easier for the staff to slide the connecting rod into the box cover, thereby avoiding excessive space occupation when the photovoltaic power box is not in use;

[0026] 2. In order to solve the problem that in the existing photovoltaic power box, although the electric-controlled telescopic rod can drive the photovoltaic panel 1 and the photovoltaic panel 2 to rise from the main box, the photovoltaic panel 1 and the photovoltaic panel 2 are exposed outside the main box when in use. After long-term use, fallen leaves and dust will fall on the surface of the photovoltaic panels, which will affect the power generation efficiency of the photovoltaic panels. The present invention provides a mounting plate at the terminal end of the connecting rod and symmetrically provides adjusting screws on both side walls of the protective box. When the photovoltaic power box is not in use, the connecting rod is retracted into the box cover, and the mounting plate can move with the movement of the connecting rod to drive the cleaning plate to push and sweep the fallen leaves and dust on the photovoltaic panel 1 and drop them into the collection frame. When the photovoltaic power box is in use, the adjusting screw is turned to drive the cleaning plate to approach the photovoltaic panel 2. The limit block and the limit groove cooperate to limit the movement of the cleaning plate. When the electric telescopic rod drives the photovoltaic panel 1 to rise, the photovoltaic panel 2 rises with it. The cleaning plate can clean the dust on the surface of the two photovoltaic panels 2, thereby preventing the power generation efficiency of the photovoltaic panel 1 and the photovoltaic panel 2 from being affected by the obstruction of fallen leaves and dust.
