Energy storage battery

Abstract

The invention relates to electric equipment, in particular to an energy storage battery. The energy storage battery comprises a pole column, a box body, a pole plate, a box cover and a lead, wherein a battery jar is formed in the box body; the pole plate is arranged in the battery jar; the box cover further comprises an upper cover and a lower cover; the edge of the upper cover is connected with the upper surface of the lower cover; a wiring exhaust space is formed between the upper cover and the lower cover; the upper cover is provided with a lead exhaust channel used for communicating the outside space with the wiring exhaust space; the lower cover is matched with the box body; a pole column hole and a vent hole used for communicating the battery jar with the wiring exhaust space are formed on the lower cover; the lower end of the pole column passes through the pole column hole to be connected with the upper part of the pole column; the inner end of the lead is connected with the upper end of the pole column; and the outer end of the lead extends into the lead exhaust channel. The energy storage battery provided by the invention fully utilizes the protective performance of a shell and omits a special protective device, so the energy storage battery is very convenient and simple in mounting, reduces the mounting cost and has high water resistance and exhaust performance.

Description

technical field [0001] The invention relates to an electric device, more specifically, to an energy storage battery. Background technique [0002] As my country's economy continues to grow steadily and rapidly, the demand for energy is also increasing rapidly, and the rapid reduction of non-renewable energy has made us face severe energy problems. [0003] In recent years, as more and more countries adopt policies and measures to encourage the use of renewable energy, the production scale and scope of use of renewable energy are expanding; among them, the photovoltaic industry of photovoltaic power generation is in the field of production and development of renewable energy develop more rapidly. [0004] With the large-scale rise of the photovoltaic industry, in the field of photovoltaic independent power generation systems, energy storage batteries are usually selected to achieve electric energy storage. The energy storage battery in the prior art will be described below ...

Problems solved by technology

[0009] Although the installation of the energy storage battery in the protective way of the buried box can play the role of waterproof and moisture-proof, and can also discharge the gas smoothly at the same time, because the box body 21 and the box cover 24 of the buried box need to be connected by multiple bolts 22 , and the locking method is complicated; this not only brings great inconvenience to the installation and connection operation, the installation process is very cumbersome, but also makes the installation cost of the energy storage battery very high

In addition, because it is difficult to ensure that the pretightening force of each bolt 22 is equal, it is easy to make the deformation of the waterproof gasket 23 different; and it is impossible to ensure that the joints of the box body 21 and the box cover 24 are in a good sealing state. Therefore, in practice In fact, it is difficult to ensure the airtightness of the buried box, so that its sealing life is difficult to match the life of the battery, so that the buried box cannot meet the needs of protecting the energy storage battery

[0010] The protection method of on-site cement pool has the disadvantages of time-consuming, labor-intensive, high cost and poor waterproof effect.

For the self-contained base such as solar street light poles and other protection methods, considering the needs of sealing and anti-theft, it is often necessary to set up special parts to close the base; furthermore, special equipment and maintenance technicians are required during maintenance or overhaul. It is very inconvenient to replace and maintain the battery, and the maintenance cost is relatively high
