Description

A drainage structures for photovoltaic energy battery cabinet

Technical Field

The utility model relates to the technical field of battery cabinets, in particular to a drainage structure for a photovoltaic energy battery cabinet.

Background

The battery cabinet theory of operation in photovoltaic new forms of energy field is that the electric energy that the solar substrate passes through the inverter conversion uses for the user, and unnecessary electric energy needs to be stored in the battery cabinet, and when night or cloudy day solar substrate do not work like this, the user still can get the electricity from the battery in the middle of, realizes the target of user's interests maximize. The design of the battery cabinet takes heat dissipation into consideration, the battery can emit more heat when working, at least two ventilation filter screens are required to be arranged on the battery cabinet, and a fan is arranged on one ventilation filter screen to meet the requirement of forced ventilation; water resistance is also considered because the ventilation screen has an IP rating of IP54, and when tested in accordance with this requirement, water can seep through the ventilation screen and the mounting interface between the screen and the battery cabinet, which can then threaten the safety of the battery.

The current design is that a whole reinforcing plate is welded at the bottom of a battery cabinet, then batteries are placed on the reinforcing plate, a drain hole is formed in the center of the bottom of the battery cabinet, and in the process of doing experiments, water seeps from a ventilation filter screen and then flows to the bottom of the batteries, so that danger is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a drainage structure for a photovoltaic energy battery cabinet, so as to solve the problems in the background technology.

In order to achieve the purpose, the utility model provides the following technical scheme: a drainage structure for a photovoltaic energy battery cabinet comprises a battery body, a battery cabinet body, reinforcing ribs and drainage holes, wherein a ventilation filter screen is arranged on the side face of the battery body; a clearance area is reserved between the reinforcing ribs and the side wall of the battery cabinet body, and the drain holes are formed in the clearance area.

Preferably, the drain holes are circular through holes, and a plurality of groups of the drain holes are arranged in the gap area; the distance between the reinforcing ribs and the side wall of the battery cabinet body is 35-45 mm.

Preferably, the bottom of the battery cabinet body is provided with a supporting base, the supporting base is of a square structure, and the bottom of the supporting base is provided with a cushion pad made of rubber materials.

Compared with the prior art, the utility model has the beneficial effects that: according to the drainage structure provided by the utility model, water permeates from the ventilation filter screen and directly flows to the drainage hole at the bottom of the battery cabinet along the side wall of the battery cabinet, so that the water does not contact with the battery and volatilizes under the influence of high temperature generated by the operation of the battery even if moisture exists, and the damage of the water to the battery is reduced to the greatest extent; the structural layout is simple and practical, the original structure is not changed through the ingenious collocation of the welding positions of the sheet metal parts and the drain holes, accessories are not additionally added, and various risks possibly caused by water seepage are solved.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1-2, the present invention provides a technical solution: a drainage structure for a photovoltaic energy battery cabinet comprises a battery body 1, a battery cabinet body 3, a reinforcing rib 4 and a drainage hole 6, wherein a ventilation filter screen 2 is arranged on the side surface of the battery body 1, the reinforcing rib 4 is arranged at the bottom end of the battery cabinet body 3, and the battery body 1 is fixedly arranged on the upper side of the reinforcing rib 4; a clearance area is reserved between the reinforcing rib 4 and the side wall of the battery cabinet body 3, and the drain hole 6 is arranged in the clearance area.

Further, the drain holes 6 are circular through holes, and a plurality of groups of the drain holes 6 are arranged in the gap area; the distance between the reinforcing ribs 4 and the side wall of the battery cabinet body 3 is 35-45 mm.

Further, a supporting base 5 is arranged at the bottom of the battery cabinet body 3, the supporting base 5 is of a square structure, and a cushion pad made of rubber materials is arranged at the bottom of the supporting base 5.

The working principle is as follows: a gap of about 40mm is reserved between the reinforcing rib 4 and the side wall of the battery cabinet body 3, and a drainage hole 6 is formed in the gap for discharging water seeping from the ventilation filter screen 2. The battery body 1 is placed on the reinforcing ribs 4, the bottom of the battery body 1 still has a space, and water entering from any place cannot contact the battery body 1, so that the operation safety of the battery body 1 is ensured.
