Technical Field
[0001] This utility model belongs to the field of energy storage device technology, and specifically relates to a micro energy storage device for industrial and commercial use. Background Technology
[0002] During the operation of industrial and commercial power transmission lines, power outages are inevitable. To avoid losses to factories and specific sites caused by power outages, industrial and commercial energy storage devices have been widely used. Existing industrial and commercial micro-energy storage devices are mainly used in grid-connected mode, where the energy storage devices are connected in parallel to the power grid to compensate for load power by releasing the stored electrical energy.
[0003] While existing industrial and commercial micro energy storage devices can meet the basic needs of power reserve, the cabinet doors of these devices are often only hinged together. When workers open the cabinet doors for maintenance, they often cannot lock them after opening. Therefore, the doors can easily be accidentally opened by others or by factors such as wind, causing them to rotate or even close on their own. This causes great inconvenience to users and thus cannot fully meet their needs. Utility Model Content
[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a micro energy storage device for industrial and commercial use. It not only meets the basic requirements for energy storage and backup power supply, but also allows for easy locking of the cabinet door when workers open it for maintenance, preventing it from rotating on its own under external force, thus better meeting people's usage needs.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a micro energy storage device for industrial and commercial use, including an energy storage cabinet body, an energy storage converter and a battery module electrically connected to the energy storage converter are arranged in the energy storage cabinet body, a cabinet door is hinged to the side end of the energy storage cabinet body, a limit cylinder is rotatably arranged inside the bottom of the cabinet door, a limit rod is inserted into the limit cylinder, a locking bolt for fixing the limit rod is screwed on the limit cylinder, a limit hook is arranged on the limit rod, and a limit hanging ring that can be connected to the limit hook is arranged on the bottom outer wall of the energy storage cabinet body.
[0006] As a further improvement of this utility model, a fixing ring is provided on the bottom inner wall of the cabinet door, and a connecting ring is provided on the limiting cylinder to fit and connect with the fixing ring. Through the cooperation of the fixing ring and the connecting ring, the rotatable connection between the limiting cylinder and the cabinet door can be realized.
[0007] As a further improvement of this utility model, a receiving frame is also provided at the bottom of the cabinet door, and the fixing ring is set in the receiving frame. The connecting ring, limiting cylinder, limiting rod and limiting hook can all be stored in the receiving frame.
