Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic equipment, in particular to a courtyard photovoltaic energy storage charging device. Background Art

[0002] Driven by the dual promotion of rural revitalization and the dual-carbon goal, the photovoltaic market is developing very vigorously. Different from large-scale photovoltaic power stations with high power and large floor area, household photovoltaic power generation in rural areas places photovoltaic panels on the top floor of family residences, uses a small-power inverter for the commutation process, and incorporates the electric energy into the power grid. It can generate electricity for self-use and feed the surplus electricity into the grid. The power grid adjusts the surplus and deficiency. For the self-used photovoltaic electricity, the electricity consumption of the power grid is automatically offset without trading. For the surplus photovoltaic electricity fed into the grid, the power grid company purchases it at the local benchmark electricity price. This household photovoltaic business is favored by the market and farmers.

[0003] This household photovoltaic can also install a photovoltaic power station in its own idle courtyard or on the large open space of the courtyard. It can make full use of the usually large area of the courtyard, install more panels, and have relatively higher power generation income, thus relieving the pressure on the roof and effectively utilizing the idle ground space. Compared with centralized photovoltaic power generation, household photovoltaic has a smaller scale, faster construction, and lower land requirements.

[0004] However, the existing household photovoltaic power generation devices cannot be folded, which is not convenient to use. With the implementation of the Beautiful Countryside Plan and the improvement of people's living standards, more and more people begin to pay attention to the creation and utilization of outdoor space. As a place for close contact with nature, the courtyard is loved by more and more people. However, in the hot summer, the strong exposure to sunlight often makes people feel uncomfortable, so shading of the courtyard is needed.

[0005] Based on the above content, the present application proposes a courtyard photovoltaic energy storage charging device applied in the courtyard, which can achieve shading and can be folded and retracted. Content of the Utility Model

[0006] The purpose of the utility model is to provide a courtyard photovoltaic energy storage charging device, which realizes the unfolding and folding of the photovoltaic module group through the cooperation of a slide rail, a sliding hook and a wire reel. When applied in the courtyard, it can meet the lighting needs of crops planted under the panel and realize the effective utilization of space.

[0007] To achieve the above purpose, the utility model provides a courtyard photovoltaic energy storage charging device, including a lightweight photovoltaic module group, an inverter and controller integrated unit, and an energy storage battery. The lightweight photovoltaic module group is electrically connected to the energy storage battery through the inverter and controller integrated unit. The output end of the inverter and controller integrated unit is respectively electrically connected to an electrical device, a power distribution cabinet, and a household charging pile. The lightweight photovoltaic module group is arranged on a photovoltaic support.

[0008] Preferably, the photovoltaic support includes two crossbeams and a slide rail group connected between the two crossbeams through slide rail fixing parts. The slide rail group includes two single-groove slide rails and multiple double-groove slide rails. The two single-groove slide rails are respectively arranged at both ends of the crossbeam, and the multiple double-groove slide rails are arranged between the single-groove slide rails at both ends; support columns are arranged at the bottoms of both ends of the two crossbeams.

[0009] Preferably, a plurality of sliding hooks are arranged in the single groove of the single-groove slide rail and in the two grooves of the double-groove slide rail, and the rightmost sliding hooks are all fixed in the groove through hook fixing parts.

[0010] Preferably, the lightweight photovoltaic module groups are all connected to the hanging rings of the sliding hooks through mounting holes. The lightweight photovoltaic module groups are formed by connecting a plurality of lightweight photovoltaic modules connected in two rows, and adjacent two lightweight photovoltaic modules are connected through connecting rings.

[0011] Preferably, a rotating assembly is arranged on the left crossbeam. The rotating assembly includes a motor and a round tube connected to the output shaft of the motor. The round tube is fixed to the upper end of the left crossbeam through a plurality of rotating shaft supports. Bearings are installed inside the rotating shaft supports, and the round tube is rotatably connected inside the bearings.

[0012] Preferably, a plurality of winch groups are arranged on the round tube. The winch group includes a first winch and a second winch. A forward rotation traction steel wire is arranged on the first winch, and the other end of the forward rotation traction steel wire is fixed to the hanging ring of a sliding hook close to the first winch.

[0013] Preferably, a fixed pulley is arranged on the right crossbeam. The setting position of the fixed pulley corresponds to the setting position of the second winch. A reverse rotation traction steel wire is arranged on the second winch, and the other end of the reverse rotation traction steel wire bypasses the fixed pulley and is connected to the hanging ring of a sliding hook close to the second winch.

[0014] Preferably, the motor is connected to an inverter integrated machine, and the input end of the inverter integrated machine is electrically connected to the municipal power grid.

[0015] Therefore, the courtyard photovoltaic energy storage charging device of the present utility model adopts the above structure. On the one hand, because the photovoltaic module has good light transmittance, while improving the beauty of the courtyard, it can also play a sunshade role; on the other hand, it can utilize photovoltaic power generation to "spontaneously use, feed the surplus power into the grid, consume nearby, and regulate the power grid", creating its own outdoor activity space; at the same time, it can be folded up and put away, bathe in the warm sunlight, and can also meet the lighting requirements of the crops planted under the board, realizing the effective utilization of space.
