Convenient-for-maintenance convergence box used for micro-grid

Abstract

The present invention discloses a convenient-for-maintenance convergence box used for a micro-grid. The convergence box comprises a fixing plate, an electric pushing rod, a groove, sliding slots, sliding blocks, a box body, a box cover, a transverse bar, a ring, a pulling rope, a guiding hole, a first spring, a first handle, heat dissipation copper pieces, an embedding frame, an annular groove, asecond spring, a water box, an inflating pump, a drying box, a coil tube, a water-adding tube, a connecting soft tube, a drawer, a second handle, through holes and drying packages. According to the convergence box, the box body can be driven to ascend and descend along the vertical direction via an ascending and descending structure, so that the convergence box is convenient for the box body to descend from a height; combining the pulling rope, the first spring, the second spring and the embedding frame, when the box body rises to the sliding blocks and contacts with the tops of the sliding slots, the box cover can be covered on the side of the opening of the box body to close the box body; and after the box body descends, the box body is pushed to allow the pulling rope to be at the samelevel with the ground, so that the box cover can be loosened from the side of the opening of the box body to open the box body, and thus the convergence box is convenient for the maintenance in the box body.

Description

technical field [0001] The invention relates to a combiner box for a microgrid, in particular to a combiner box for a microgrid that is easy to maintain, and belongs to the technical field of combiner box applications. Background technique [0002] Microgrid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc.; combiner boxes in microgrid photovoltaic power generation systems ensure orderly connection and confluence of photovoltaic modules Functional wiring device. [0003] The combiner box is generally installed at a high place, and the opening of the combiner box is generally closed by a box cover. When the combiner box fails, it may be necessary to climb up for maintenance. The labor intensity of the maintenance may be large, and the maintenance is wasteful.

Problems solved by technology

[0003] The combiner box is generally installed at a high place, and the opening of the combiner box is generally closed by a box cover. When the combiner box fails, it may be necessary to climb up for maintenance. The labor intensity of the maintenance may be large, and the maintenance is wasteful. The combiner box is generally set outdoors. When the weather is humid, the humid air may enter the box and cause damage to the internal components of the box. When the combiner box is working, it will generate heat by itself. When the weather is hot, the heat may be difficult to dissipate from the inside of the box, and the internal components of the box are exposed to high temperature for a long time, which may cause damage to the internal components of the box; there may be hail weather or falling objects in the air outdoors , may impact the box body, the general combiner box may lack buffer and anti-collision devices, and may not be able to reduce the damage to the combiner box
