Description
Technical Field
The utility model relates to an energy storage power station, in particular to a battery box valve of the energy storage power station.
Background
In order to reduce fire risk, the prior battery box of the energy storage power station is internally provided with a plurality of battery packs, the closed battery box is filled with nitrogen, as shown in fig. 1, a through hole 11 ' is formed in the wall 1 ' of the battery box, a one-way valve 2 ' is fixedly connected to the wall of the battery box outside the through hole 11 ', a spring 21 ' is arranged in the one-way valve 2 ' to press a valve plate 22 ' to close a valve port, and threads (not shown in the figure) are arranged outside the valve body to connect an air charging pipe or a fire extinguishing pipe. In the existing structure, since only one gas through hole (not including other electric cable through holes) is formed in the battery box, the nitrogen concentration and the pressure in the box body cannot be monitored in time, if the monitoring holes are formed in the battery box body, the monitoring holes are required to be agreed by a battery box manufacturer (the problem of liability caused by changing the structure of the battery box), and the battery box is required to be finished and then the monitoring holes can be continued, so that the nitrogen concentration and the pressure in the box body cannot be monitored in time, and the nitrogen concentration and the pressure in the box body cannot be realized.
Disclosure of Invention
The utility model aims to provide a connecting valve body capable of realizing connection pressure and concentration monitoring on an existing battery box.
In order to achieve the above purpose, the connecting valve body of the energy storage battery box is provided with the one-way valve, wherein one end of the connecting valve body is connected with the one-way valve in a threaded manner, the connecting valve body is internally provided with a pressing device for pressing a valve plate of the one-way valve, the connecting valve body is provided with a quick connector for connecting a pressure sensing device and a concentration sensing device, and the other end of the connecting valve body is provided with the one-way valve connected with an air inlet pipeline.
After the scheme is adopted, the structure and the function of the primary battery box do not need to be changed, the pressure and concentration monitoring sensor can be connected quickly through the connecting valve body, and the structure is simple and the operation is convenient.

Detailed Description
In order to describe the technical content, the constructional features, the achieved objects and effects of the present utility model in detail, the following description is made in connection with the embodiments and the accompanying drawings.
Referring to fig. 2 and 3, in the energy storage battery box connecting valve body of the present utility model, a connecting valve body 3 is screwed (threads are not shown) on a check valve 2', and a pressure sensor interface 32 and a concentration sensor interface 33 for connecting a pressure sensor 4 and a concentration sensor 5 are provided on the connecting valve body 3. In the process that the connecting valve body 3 is internally provided with the thimble 31 to connect the valve body 3 in the one-way valve 2 ', the thimble 31 pushes the valve plate 22' open so that nitrogen filled in the battery box can enter the connecting valve body, and the thimble can adopt other forms of pressing devices. The interface between the pressure sensor 4 and the concentration sensor 5 and the connecting valve body 3 is a quick-connection interface, and a switch is arranged between the concentration sensor 5 and the connecting valve body 3. The other end of the connecting valve body 3 is provided with a one-way valve with the same structure as the original one-way valve on the battery box, under the normal state, the one-way valve plate 34 of the connecting valve body is propped against the air inlet hole 35, when the air inlet pipe is in threaded connection with the air inlet pipe connecting thread 36 on the connecting valve body 3, the one-way valve plate 34 of the connecting valve body is propped up to form an air inlet channel, and then nitrogen is supplemented to the battery box or fire extinguishing gas is sprayed into the battery box.
The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent shapes or structural changes made by the present utility model and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the present utility model.
