Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic energy storage, and particularly relates to a photovoltaic energy storage cabinet. Background Art

[0002] A photovoltaic energy storage cabinet is a device integrating photovoltaic power generation and battery energy storage functions. It mainly consists of a photovoltaic panel, a battery pack, a charge controller, an inverter, a power management system, etc. This device can not only generate electricity using solar energy but also provide electricity through the battery energy storage system during peak power demand.

[0003] The mobility and long-term stability of the energy storage cabinet are limited by the structural design. For example, traditional roller supports may cause deformation of the device, and the supporting cabinet body will be deformed under the action of the battery load during use. At the same time, the air inlets of existing outdoor-deployed energy storage cabinets are prone to adsorbing dust and sand particles, and long-term accumulation will block the air ducts, reducing the heat dissipation efficiency and exacerbating the temperature rise problem. Some solutions use self-cleaning components. Although the filter screen can be cleaned by a rotating brush plate, it relies on a specific mechanical structure and has a high maintenance cost.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0041] As Figure 1 shown, this embodiment is a photovoltaic energy storage cabinet, including a mobile support platform and an energy storage cabinet body 3; As Figure 2 shown, a cabinet door 5 is in an open state. The structural strength of the photovoltaic energy storage cabinet is improved through the mobile support platform, and the photovoltaic energy storage cabinet can be effectively carried and transported

[0042] As Figure 3As shown in the figure, the energy storage cabinet body 3 includes an energy storage support frame 301. A support base 302 is fixed at the bottom of the energy storage support frame 301. A diversion fan group 303 is arranged at the top of the energy storage support frame 301. The internal environment of the energy storage cabinet body 3 is disturbed by the diversion fan group 303, so that cold and hot air absorb each other. An inverter, a controller and an energy storage battery module are arranged in the energy storage support frame 301, and the overall load is relatively large. The support base 302 adopts a rectangular frame structure arranged in a mesh pattern. Threaded holes are arranged at the bottom of the support base 302.

[0050] At both ends of the cabinet door 5, a rubber sealing strip is respectively fixed. Through the elastic fitting between the rubber sealing strip and the first substrate 1 and the second substrate 2, the sealing of the photovoltaic energy storage cabinet is improved. A door handle is also provided on the cabinet door 5 to facilitate opening and closing of the cabinet door 5.
