Description

TECHNICAL FIELD

[0001] The application relates to an energy storage device, in particular an energy storage device of a stereo garage photovoltaic power generation system, and belongs to the technical field of energy storage. BACKGROUND

[0002] The stereo garage can vertically park and stack vehicles, thereby greatly saving the land area occupied by urban vehicle parking, and is one of the main means for solving the parking problem in many large cities. The stereo garage top-mounted photovoltaic power generation system can not only effectively utilize the top light energy, but also can reduce a part of the power consumption of the stereo garage. The photovoltaic power generation system needs to be used in combination with an energy storage device, and the energy storage device needs to occupy a certain volume. When the existing stereo garage is upgraded and modified, the original control cabinet design does not include the installation space of large devices such as the energy storage device, so the installed energy storage device usually needs to be external. The external energy storage device needs to be connected with the control system of the control cabinet through a connecting line. If the connecting line is directly exposed, it is easy to be stepped on and dragged by other objects, causing damage to the insulating layer of the connecting line. Moreover, if the city is near the sea, the air is humid and salty, and the exposed connecting line will be accelerated aging. In addition, in order to reasonably utilize the installation space, the energy storage device usually needs to be installed in the corner and other narrow spaces, and the maintenance space is small, and the operation is very inconvenient.

When the connecting line 2 is in a right angle transition at the bottom of the energy storage box and the floor, the long strip tooth 15 of the connecting rod 14 of the latter fixed protection unit is rotated in the circular groove 17 to be parallel to the longitudinal groove 18, the connecting rod 14 of the latter fixed protection unit is pressed down at this time, the long strip tooth 15 of the latter fixed protection unit slides downward along the longitudinal groove 18 of the former fixed protection unit until it slides to the bottom of the longitudinal groove 18, at this time, the long strip tooth 15 is completely clamped in the longitudinal groove 18, so that the two fixed protection units are arranged at right angles.
