Description
Technical Field
The invention relates to the technical field of battery compartment guarantee, in particular to a battery room environment guarantee system.
Background
With the increasing popularity of ocean-going steel passenger ships, the storage battery pack is used as a backup energy source when a main or emergency power supply fails, and the storage battery pack is more and more widely applied.
The backup electric energy provided for temporary emergency lighting mainly depends on a maintenance-free lead-acid storage battery pack, and when a main power supply or an emergency power supply fails, the storage battery pack normally provides electric energy to ensure that whether passengers and crews can safely evacuate or not, whether the visibility of a control place can be ensured or not and whether firefighter equipment can reach or not.
In order to ensure the normal operation and maintenance of the storage battery, the maintenance-free lead-acid storage battery pack fixed on a special storage rack is usually arranged in a special storage battery room for use in emergency.
The lead-acid storage battery is a high-pollution and dangerous product, hydrogen can be separated out from the lead-acid storage battery in the charging process, and the hydrogen belongs to flammable and explosive gas, so that strict requirements are imposed on the use environment and storage battery rooms of the lead-acid storage battery.
At present, the design scheme of a ventilation system of a storage battery room is as follows: natural air intake and single-speed axial flow centrifugal fan exhaust. This scheme only can satisfy battery service environment's minimum operation requirement of manually opening the fan of airing exhaust when needing crewman's manual work to patrol and examine. The storage battery pack itself, its operating state and the environment are not functionally interlocked.
At present, the existing design method has strong dependence on the external environment due to the adoption of a natural air inlet mode; the single-speed axial flow centrifugal fan exhausts air, and the electric energy consumption is large during operation.

The requirement on the crew is high, and the system reliability is low.
However, this solution has the following disadvantages:

2) the scheme cannot accurately judge whether the content of the inflammable gas in the storage battery room reaches the warning value, so that potential safety hazards are easy to be undetected for a long time;
3) the existing design scheme cannot ensure that an exhaust fan is started in time in each charging process of the storage battery pack, so that inflammable gas in a storage battery room is easy to accumulate, and the concentration is increased;
4) the guarantee of the storage battery room environment does not participate in the temperature of the storage battery body, and when the temperature of the storage battery body is too high, effective cooling measures are not provided.
