Abstract

An outdoor energy storage system cabinet and an outdoor energy storage system are provided. The cabinet includes a cabinet body, a water firefighting system, and a gas firefighting system. The water firefighting system includes a water firefighting pipe. The water firefighting pipe is arranged at a top part of an interior of the cabinet body and is provided with a water nozzle. The gas firefighting system includes a gas firefighting pipe. The gas firefighting pipe, like the water firefighting pipe, is arranged on the top part of an interior of the cabinet body. The gas firefighting pipe is configured to contain a firefighting fire extinguishing agent or transport the firefighting fire extinguishing agent. The gas firefighting pipe is provided with an air nozzle for ejecting firefighting gas generated by the firefighting fire extinguishing agent.

First claim

The invention claimed is:

a cabinet body;
a water firefighting system having a water firefighting pipe, wherein the water firefighting pipe is arranged at a top part of an interior of the cabinet body and is provided with a water nozzle;
a gas firefighting system having a gas firefighting pipe, wherein the gas firefighting pipe is arranged at the top part of an interior of the cabinet body and is configured to contain a firefighting fire extinguishing agent or transport the firefighting fire extinguishing agent, and the gas firefighting pipe is provided with an air nozzle for ejecting firefighting gas generated by the firefighting fire extinguishing agent; and
a top-mounted integrated air conditioner, wherein a top of the cabinet body is provided with a mounting groove, and the top-mounted integrated air conditioner is embedded in the mounting groove,
wherein a front side of the cabinet body is provided with a cabinet body air inlet, a rear side of the cabinet body is provided with a cabinet body air outlet, the cabinet body air inlet and the cabinet body air outlet are connected to the mounting groove, an external air inlet of the top-mounted integrated air conditioner is connected to the cabinet body air inlet, and an external air outlet of the top-mounted integrated air conditioner is connected to the cabinet body air outlet.

2. The outdoor energy storage system cabinet according to claim 1 , wherein the gas nozzle is connected to the gas firefighting pipe via a stop valve, the stop valve is configured to allow the gas nozzle to be in communication with the gas firefighting pipe or not in communication with the gas firefighting pipe, the stop valve is connected to a trigger apparatus, and the trigger apparatus is configured to trigger the stop valve to allow the gas nozzle to be in communication with the gas firefighting pipe when a fire occurs in the cabinet body.

3. The outdoor energy storage system cabinet according to claim 2 , wherein the trigger apparatus comprises a controller and at least one of a temperature sensor and a smoke sensor, wherein
the controller is configured to control the stop valve to connect the gas nozzle to the gas firefighting pipe when temperature in the cabinet body exceeds a first temperature threshold; and/or
the controller is configured to control the stop valve to connect the gas nozzle to the gas firefighting pipe when smoke concentration in the cabinet body exceeds a first smoke concentration threshold.

4. The outdoor energy storage system cabinet according to claim 3 , further comprising an alarm apparatus connected to the controller, wherein
the controller is configured to control the alarm apparatus to alarm when a temperature in the cabinet body exceeds a second temperature threshold, and the second temperature threshold is not greater than the first temperature threshold; and/or
the controller is configured to control the alarm apparatus to alarm when a smoke concentration in the cabinet body exceeds a second smoke concentration threshold, and the second smoke concentration threshold is not greater than the first smoke concentration threshold.

5. The outdoor energy storage system cabinet according to claim 2 , wherein the trigger apparatus is a manual trigger apparatus comprising an operation apparatus arranged on an outer wall of the cabinet body, and the operation apparatus is connected to the stop valve.

6. The outdoor energy storage system cabinet according to claim 1 , wherein the mounting groove is provided with a partition plate for partitioning the cabinet body air inlet and the cabinet body air outlet.

7. The outdoor energy storage system cabinet according to claim 6 , wherein a bottom of the mounting groove is provided with a plurality of mounting positions for mounting the top-mounted integrated air conditioner, and the mounting positions are provided with openings throughout which an internal air inlet and an internal air outlet of the top-mounted integrated air conditioner extend into the cabinet body.

8. The outdoor energy storage system cabinet according to claim 2 , further comprising a top-mounted integrated air conditioner, a top of the cabinet body is provided with a mounting groove, and the top-mounted integrated air conditioner is embedded in the mounting groove.

9. The outdoor energy storage system cabinet according to claim 3 , further comprising a top-mounted integrated air conditioner, a top of the cabinet body is provided with a mounting groove, and the top-mounted integrated air conditioner is embedded in the mounting groove.

10. The outdoor energy storage system cabinet according to claim 4 , further comprising a top-mounted integrated air conditioner, a top of the cabinet body is provided with a mounting groove, and the top-mounted integrated air conditioner is embedded in the mounting groove.

11. The outdoor energy storage system cabinet according to claim 5 , further comprising a top-mounted integrated air conditioner, a top of the cabinet body is provided with a mounting groove, and the top-mounted integrated air conditioner is embedded in the mounting groove.

12. An outdoor energy storage system, comprising:
an energy storage battery cluster;
an alternating current and direct current combining cabinet;
a string inverter; and
the outdoor energy storage system cabinet according to claim 1 , wherein
the energy storage battery cluster, the alternating current and direct current combining cabinet and the string inverter are arranged in the cabinet body of the outdoor energy storage system cabinet.
