[0127] Specifically, the cabinet body 2 can provide stable support for the support plate 30, so that the support plate 30 supports the blowing fan 31. When the blowing fan 31 is started, suction will be generated to suck the outside air into the inner side of the cabinet body 2 through the air hole 7 through the cabinet top 6. The wind hood 12 can provide support for the exhaust fan 13 with the support of the cabinet bottom 1. When the exhaust fan 13 is started, the gas in the cabinet body 2 can be sucked in and discharged to the outside through the cabinet bottom 1.

[0128] In the actual application of this embodiment, the water entering the storage tube 14 will flow into the inner side of the water cover 19, fill the water cover 19 and flow into the inner side of the hollow curved plate 20 and the L plate 21, and then the water will flow into the inner side of the receiving barrel 24 along the hollow curved plate 20 and the L plate 21 under the action of gravity. When the water flows along the hollow curved plate 20 and the L plate 21, it will absorb and take away the heat on the heat conducting plate 22, and the copper busbar 23 will contact the photovoltaic energy storage battery 11, and absorb and conduct the heat generated by the photovoltaic energy storage battery 11 to the copper busbar 23 when in contact. At the same time, the staff needs to start the circulation pump 25, so that the circulation pump 25 can absorb and take away the heat flowing into the receiving barrel 24 through the connecting pipeline under the support of the receiving barrel 24. A large amount of water is discharged to the inner side of the discharge pipe 26, so that the water flows into the inner side of the connecting tube 27 along the discharge pipe 26. When the connecting tube 27 is full of water, the water will enter the inner side of the buffer tube 28 for collection, storage and buffering. When the buffer tube 28 is full of water, the water after absorbing heat will flow into the inner side of the serpentine tube 29, and flow into the inner side of the storage tube 14 along the serpentine tube 29 for recycling. While the water flows in the serpentine tube 29, the staff needs to start the blowing fan 31 in advance under the support of the support plate 30, so that the blowing fan 31 sucks the outside air from the air hole 7, and blows it to the serpentine tube 29 through the support plate 30, and uses the wind to cool the water flowing in the serpentine tube 29, thereby cooling the water after absorbing heat so that it can be recycled repeatedly;

[0129] When the blowing fan 31 is started, a part of the blown wind will pass through the serpentine tube 29 and blow toward the electrical facilities installed on the mounting frame 8. At the same time, the staff needs to start the exhaust fan 13 under the support of the wind hood 12, so that the exhaust fan 13 can suck the air in the cabinet 2 from the air outlet into the inner side of the wind hood 12, and discharge it to the outside through the wind hood 12, thereby realizing the exchange of air inside the cabinet 2 and the outside air, providing a certain cooling effect.

[0137] Specifically, the waterproof cylinder can provide a space for the opening 33 under the support of the water cover 19, and the opening 33 can provide a channel for the water in the waterproof cylinder to be discharged into the cabinet 2, and the waterproof cylinder can provide rotational support for the rotating rod 34, and the rotating rod 34 can provide support for the baffle plate 35, and the baffle plate 35 can firmly support the sealing ring 36. When the sealing ring 36 is in contact with the waterproof cylinder, it can close the opening 33 to prevent the water in the drain cylinder 32 from flowing out to the outside.

[0138] The resistance parts include:

[0139] Bismuth strip 37, fixed on the side of baffle plate 35 away from water discharge cylinder 32;

[0140] The copper bar 38 is fixed to the end of the bismuth bar 37 away from the baffle 35;

[0141] A copper rod 39 is fixed to an end of the copper bar 38 away from the bismuth bar 37;

[0142] The copper block 40 penetrates the copper busbar 23 and is fixedly connected thereto, and is located at a position where the copper busbar 23 extends out of the L-plate 21 and the hollow bent plate 20;

[0143] The retaining ring 52 is fixedly mounted on the outer side of the copper strip 38 and is located close to the bismuth strip 37 .

[0144] Specifically, there are a plurality of copper bars 38, and a copper plate 41 is connected in series between the plurality of copper bars 38. The melting point of the bismuth bar 37 is 271 degrees Celsius, and the temperature of thermal runaway of the photovoltaic energy storage battery 11 is above 250 degrees Celsius, and the melting point of the copper material is 1084.6 degrees Celsius.

When the photovoltaic energy storage battery 11 is thermally runaway, the copper busbar 23 will transfer heat to the bismuth bar 37 through the copper block 40, the copper rod 39, the copper plate 41 and the copper bar 38, so that the bismuth bar 37 is heated and heated. When the bismuth bar 37 is heated to 271 degrees Celsius The bismuth strip 37 will be melted after being melted, and the water in the water discharge cylinder 32 will use gravity to push the baffle plate 35, so that the baffle plate 35 drives the sealing ring 36 to rotate clockwise around the rotating rod 34 as the center under the action of external force. At the same time, the baffle plate 35 will use the rotating external force to push the melted bismuth strip 37, so that the bismuth strip 37 breaks and separates from the copper strip 38, thereby releasing the resistance to the baffle plate 35, thereby opening the through port 33, so that the water in the water discharge cylinder 32 can pass through the through port 33 into the inner side of the cabinet 2.

[0154] Sealing parts include:

[0155] The rubber strip 42 movably passes through the side of the wind shield 12 away from the guide plate 46 and is located on the inner side of the air outlet and fits with the wind shield 12;

[0156] A connecting plate 43 is fixed to the end of the rubber strip 42 away from the air outlet;

[0157] The support block 44 is fixed to a side of the wind shield 12 close to the photovoltaic energy storage battery 11;

[0158] A spring 45, one end of which is fixedly connected to the support block 44, and the other end of which is fixedly connected to the connecting plate 43, and is in a stretched state;

[0159] One end of the connecting rope 47 passes through the connecting plate 43 and is fixed thereon, and the other end is connected to the pulling rope 48 .

[0160] Specifically, the wind hood 12 can provide an opening space for the air outlet, and the air outlet can provide a through channel for air and water. The rubber strip 42 can be embedded with the air outlet, and the wind hood 12 can use the air outlet to provide support and movement guidance for the rubber strip 42. The rubber strip 42 is made of rubber and can provide support for the connecting plate 43. The connecting rope 47 can pull the connecting plate 43 under the tension of the pull rope 48, and the wind hood 12 can firmly support the support block 44 under the support of the cabinet bottom 1. The support block 44 can provide support for one end of the spring 45, and the connecting plate 43 can stretch the spring 45 through the other end of the spring 45 under the tension of the connecting rope 47, so that the spring 45 remains in a stretched state, thereby keeping the air outlet in an open state.

[0161] In the actual application of this embodiment, when the bismuth strip 37 melts, the hanging ring 51 will be separated from the outer side of the bismuth strip 37, and at the same time, the spring 45 will use its own rebound force under the support of the support block 44 to pull the hanging ring 51 and the interconnection rope 50 toward the support block 44 through the connecting plate 43, the connecting rope 47, the pulling rope 48 and the converging rope 49 under the support and guidance of the guide plate 46. At the same time, the spring 45 will use its own elastic force to push the rubber strip 42 through the connecting plate 43, so that the rubber strip 42 moves along the air outlet toward the support block 44, thereby closing the air outlet. The opening plays a sealing role at the air outlet, thereby preventing water that flows into the cabinet body 2 through the opening 33 from being discharged to the outside through the air outlet. At the same time, the sealing effect achieved by the cooperation of the cabinet body 2 and the cabinet door 4 can store water on the inner side of the cabinet body 2. At the same time, the amount of water discharged into the cabinet body 2 will only overflow the position where the photovoltaic energy storage battery 11 is located, so that the photovoltaic energy storage battery 11 can be soaked in water, so as to utilize the soaking of water to control the thermal runaway photovoltaic energy storage battery 11, provide protection for the battery cabinet and its inner electrical facilities other than the photovoltaic energy storage battery 11, and improve safety.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
