Abstract

The utility model relates to a battery cabinet which comprises a cabinet body and a fire extinguishing device. The fire extinguishing device comprises an inhibitor bottle, a container valve and a fire detection pipe. When a fire occurs in the cabinet and causes the temperature to rise above a predetermined temperature, the fire-detecting tube ruptures thereby moving the piston to the second position. At the moment, the liquid outlet is communicated with the inlet, and the fire extinguishing agent in the inhibitor bottle can enter the piston cavity from the inlet and is discharged to the cabinet body through the liquid outlet, so that automatic fire extinguishing is realized. Therefore, the battery cabinet does not adopt a detector and a controller when realizing automatic fire extinguishing, so that a signal transmission line is not required to be arranged. Moreover, because the inhibitor bottle of the fire extinguishing device is arranged inside the cabinet body, the fire extinguishing agent discharged from the inhibitor bottle can directly enter the cabinet body, so that a complex connecting pipeline is not required to be arranged, and the fire extinguishing agent is guided into the cabinet body when a fire occurs. Therefore, the battery cabinet can remarkably reduce the cost while simplifying the structure.

The utility model provides a battery cabinet. Referring to fig. 1, the battery cabinet includes a cabinet body (not shown) and a fire extinguishing apparatus 100.

The cabinet body is provided with an accommodating cavity which can accommodate and fix the battery. The cabinet body can be formed by splicing metal plates, and can be closed or open. The fire extinguishing apparatus 100 is also housed in the housing chamber. The fire extinguishing apparatus 100 can discharge a fire extinguishing agent into the cabinet in case of a fire, thereby achieving fire extinguishing.

Referring also to fig. 2, the fire extinguishing apparatus 100 according to the preferred embodiment of the present invention includes an inhibitor bottle 110, a container valve 120 and a fire-detecting tube 130.

The suppressant bottle 110 is used to store a fire suppressant and is filled with a relatively large gas pressure therein. The number of the inhibitor bottles 110 in the fire extinguishing apparatus 100 may be one or plural, and the number of the inhibitor bottles 110 in this embodiment is three. The inhibitor bottle 110 is fixed in the housing chamber. Specifically, in the present embodiment, the fire extinguishing apparatus 100 further includes a box body 140, the box body 140 is fixed in the accommodating cavity, and the inhibitor bottle 110 is fixed in the box body 140. The box 140 may be formed by splicing a plurality of plates, and the inhibitor bottle 110 may be fastened to the bottom surface of the box 140 by using a hoop.

Referring also to fig. 3, the container valve 120 includes a valve body 121 and a piston 122. The valve body 121 has an inlet (not shown), an outlet (not shown) and a piston chamber 1211. The inlet of the valve body 121 is communicated with the bottle mouth of the inhibitor bottle 110, and in the case of including a plurality of inhibitor bottles 110, a plurality of inlets are correspondingly arranged on the valve body 121 to realize the flow concentration of the plurality of inhibitor bottles 110. The inlet and the outlet are respectively communicated with both ends of the piston chamber 1211, and the piston 122 is slidably disposed in the piston chamber 1211. Specifically, the piston 122 divides the piston cavity 1211 into two chambers, and the inlet and the outlet are respectively communicated with the two chambers. When a pressure differential exists between the two chambers, the piston 122 is able to slide along the piston cavity 1211 under the pressure differential.

Further, a liquid outlet 1212 is further formed in a side wall of the piston cavity 1211, and the piston 122 slides in the piston cavity 1211, so that the liquid outlet 1212 is disconnected from or communicated with the inlet of the valve body 121. Specifically, when the piston 122 is in the first position, the liquid outlet 1212 is disconnected from the inlet; when the piston 122 is at the second position, the liquid outlet 1212 is connected to the inlet. The first position is located at an end of the piston chamber 1211 adjacent to the inlet of the valve body 121, and the second position is located at an end of the piston chamber 1211 adjacent to the outlet of the valve body 121.

Specifically, in the present embodiment, a step (not shown) is formed at an end of the piston cavity 1211 close to the inlet, and the piston 122 can be abutted against the step under the action of the pressure difference to move to the first position.

The firewire tube 130 is in communication with the outlet and is capable of rupturing upon reaching a predetermined temperature. Specifically, the probe tube 130 may be pre-filled with a gas such as nitrogen to form a higher pressure. The firewire 130 may be softened and broken when heated and the temperature reaches a predetermined temperature, so that the air pressure of the firewire 130 is sharply decreased.

In this embodiment, the fire extinguishing apparatus 100 further includes a ball valve 150 disposed between the outlet and the fire probe 130. A ball valve 150 acts as a switch between the outlet and the firetube 130. When the fire extinguishing apparatus 100 is in standby, the ball valve 150 is opened. When the fire extinguishing apparatus 100 is not in use, the ball valve 150 is closed, thereby effectively preventing the air pressure in the fire probe 130 from leaking.

When the fire suppression apparatus 100 is assembled, the probe tube 130 is filled with sufficient gas to allow the pressure within the probe tube 130 to be greater than the pressure within the suppressant bottle 110. In this manner, piston 122 will be in the first position and will remain balanced in the first position due to the pressure differential, thereby disconnecting outlet port 1212 from the inlet port.

When a fire occurs in the cabinet and the firetube 130 is broken, the pressure in the firetube 130 drops sharply. At this time, the piston 122 will move to the second position under the action of the pressure difference and make the liquid outlet 1212 communicate with the inlet. The fire suppressant in the suppressant bottle 110 may enter the piston chamber 1211 through the inlet under the action of the internal pressure and is finally discharged into the cabinet through the outlet 1212, thereby achieving automatic fire suppression.

Therefore, when the battery cabinet realizes automatic fire extinguishing, the battery cabinet does not need any power supply, special smoke and temperature detectors and a complex signal transmission line, and the fire extinguishing agent can be immediately released from the inhibitor bottle 110 to extinguish fire by utilizing the pressure stored in the fire detection pipe 130 when the battery cabinet is broken. In addition, the inhibitor bottle 110 is disposed inside the cabinet, and the fire extinguishing agent discharged from the inhibitor bottle 110 can directly enter the cabinet, so that it is not necessary to provide a complicated connecting line to introduce the fire extinguishing agent into the cabinet in case of a fire.

Specifically, in the present embodiment, the siphon 111 is provided at the mouth of the inhibitor bottle 110, and the siphon 111 extends toward the bottom of the inhibitor bottle 110. The fire extinguishing agent in the inhibitor bottle 110 can be guided out to the bottle opening through the siphon tube 111, which is beneficial to fully discharging the fire extinguishing agent at the bottom of the inhibitor bottle 110.

Specifically, in the present embodiment, the fire extinguishing apparatus 100 further includes a temperature sensing element 160, the temperature sensing element 160 is in communication with the inhibitor bottle 110 through the container valve 120, and the temperature sensing element 160 can be broken when a preset temperature is reached.

The temperature sensing assembly 160 may be disposed on the back of the case 140. Specifically, the temperature sensing assembly 160 generally comprises a closed length of glass tubing. When the ambient temperature near the temperature sensing assembly 160 reaches a preset temperature, the glass tube is broken. At this time, the temperature sensing assembly 160 will be used as a discharge channel, and the fire extinguishing agent in the suppressant bottle 110 can overflow into the cabinet through the temperature sensing assembly 160, thereby realizing the full-submerged fire extinguishing.

The temperature sensing assembly 160 is disposed at a position different from that of the fire tube 130. When a fire occurs in the cabinet body, but the fire detecting tube 130 is not triggered in time, the temperature sensing assembly 160 can be used as an auxiliary measure, so that the safety performance of the battery cabinet is further improved.

In this embodiment, the fire extinguishing apparatus 100 further includes a pressure gauge 170, and the pressure gauge 170 is in communication with the suppressant bottle 110 through the container valve 120. The pressure gauge 170 may be disposed on the front surface of the case 140, and may monitor the pressure in the inhibitor bottle 110 in real time.

Specifically, in the present embodiment, the fire extinguishing apparatus 100 further includes a signal feedback unit 181 and a communication board 182, and the signal feedback unit 182 is in communication with the inhibitor bottle 110 through the container valve 120 and is electrically connected to the communication board 182. A communication board 182 can be disposed on the front surface of the case 140, and a signal feedback unit 182 can introduce a pressure signal from the container valve 120 and transmit the pressure signal to the communication board 182, thereby monitoring the operation state of the fire extinguishing apparatus 100.

Specifically, in this embodiment, the fire extinguishing apparatus 100 further includes a spraying assembly 190, and the spraying assembly 190 includes a pipeline (not shown) communicating with the liquid outlet 1212 and a spraying head 191 connected to an end of the pipeline. The fire extinguishing agent discharged through the liquid outlet 1212 is sprayed from the spray head 191 so that the fire extinguishing agent can be directly sprayed to the fire point. Compared with the full-submerged fire extinguishing mode, the fire extinguishing mode can save fire extinguishing agents and can also be suitable for the open cabinet body.

Further, in the present embodiment, the spray heads 191 are plural and distributed in the cabinet. The plurality of spray heads 191 arranged in a distributed manner can spray the fire extinguishing agent more uniformly, thereby improving the fire extinguishing effect.

In the above battery cabinet, when a fire occurs in the cabinet body and the temperature rises above a preset temperature, the fire detection pipe 130 is broken to move the piston 122 to the second position. At this time, the outlet 1212 is connected to the inlet, and the fire extinguishing agent in the suppressant bottle 110 can enter the piston chamber 1211 through the inlet and be discharged to the cabinet through the outlet 1212, so as to achieve automatic fire extinguishing. Therefore, the battery cabinet does not adopt a detector and a controller when realizing automatic fire extinguishing, so that a signal transmission line is not required to be arranged. In addition, since the inhibitor bottle 110 of the fire extinguishing apparatus is disposed inside the cabinet, the fire extinguishing agent discharged from the inhibitor bottle 110 can directly enter the cabinet, and thus, there is no need to provide a complicated connecting line for introducing the fire extinguishing agent into the cabinet in case of a fire. Therefore, the battery cabinet can remarkably reduce the cost while simplifying the structure.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the utility model. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the utility model, and these changes and modifications are all within the scope of the utility model. Therefore, the protection scope of the present patent shall be subject to the appended claims.
