Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1, the utility model relates to a multipurpose pipeline structure of a battery energy storage system, the multipurpose pipeline is installed in a box body 1 of the battery energy storage system, one end of the multipurpose pipeline is respectively connected with a temperature control subsystem 3 and a fire protection subsystem 4 of the battery energy storage system through two manifolds 2, the other end of the multipurpose pipeline is provided with a plurality of branch pipelines 5, and the branch pipelines 5 are provided with a plurality of nozzles 6 which can spray to the arrangement positions of stacked battery packs; the multipurpose pipeline is also provided with a mode selection valve, and the multipurpose pipeline can be occupied by the temperature control subsystem 3 or the fire protection subsystem 4 through the mode selection valve.
The temperature control subsystem 3 is used for injecting air or other gases with lower or higher temperature than the inside of the energy storage box body into one end of the multipurpose pipeline so as to maintain the normal working environment temperature of the battery pack. The fire fighting subsystem 4 is intended to feed a pressurized extinguishing medium in liquid or gaseous form to one end of the multi-purpose pipeline. It should be noted that the temperature control subsystem 3 and the fire protection subsystem 4 of the battery energy storage system, as well as the stacked battery pack, are all in the prior art. In addition, a plurality of sets of the multipurpose pipelines can be installed in the box body 1 of the battery energy storage system, and the nozzles 6 of the multipurpose pipelines are respectively aligned to the battery packs at different positions in the energy storage system.
The multipurpose pipeline provides the following two control modes of the mode selection valve:
control mode one
As shown in fig. 2, the mode selection valve is two solenoid valves 7, the two solenoid valves 7 are respectively disposed on the manifold 2 connected to the temperature control subsystem 3 and the fire protection subsystem 4, and the two solenoid valves 7 are connected to and controlled by the control system of the energy storage system.
When the temperature control subsystem 3 is required to inject air or other gas with lower or higher temperature than the inside of the energy storage box into one end of the multipurpose pipeline so as to maintain the normal working environment temperature of the battery pack, the control system of the energy storage system controls the electromagnetic valve 7 on the manifold 2 connected with the fire protection subsystem 4 to be closed, and simultaneously controls the electromagnetic valve 7 on the manifold 2 connected with the temperature control subsystem 3 to be opened. When the fire fighting subsystem 4 is required to inject liquid or gaseous pressurized fire extinguishing medium into one end of the multipurpose pipeline, the control system of the energy storage system controls the electromagnetic valve 7 on the manifold 2 connected with the fire fighting subsystem 4 to be opened, and controls the electromagnetic valve 7 on the manifold 2 connected with the temperature control subsystem 3 to be closed.
Control mode two
To further simplify the overall piping system, the mode selection valve is designed as a check valve 8, the check valve 8 being provided on the manifold 2 connected to the temperature control subsystem 3, since the use of a programmable valve such as a solenoid valve 7 is expensive and heavy.
Under this kind of control mode, when the fire control subsystem 4 took this multipurpose pipeline, because the pipe pressure of the liquid or gaseous fire-extinguishing medium through the pipeline is greater than cold and hot control by temperature change gas manifold 2 far away, consequently, the automatic pressure-bearing of the one-way check valve 8 that corresponds manifold 2 is closed, and the fire-extinguishing medium can not get into control by temperature change subsystem 3. The check valve 8 is not required to be arranged in the manifold 2 of the fire fighting subsystem 4, and when the temperature control subsystem 3 occupies the multipurpose pipeline, cold and hot temperature control gas can not cause any harm when entering the manifold 2 of the fire fighting subsystem 4.
In order to further ensure the sealing performance of the check valve 8, an inner ring step-shaped sealing ring 9 is arranged at the sealing part of a valve plate of the check valve 8 and the manifold 2.
