When the energy storage cabinet is affected by sandstorms, it is very easy to affect the air cooling heat dissipation, and most of the sand and dust can easily penetrate into the cabinet. Manual maintenance is relatively frequent, and it is difficult to detect sandstorms and issue early warnings in the first place. Summary of the Invention

[0006] Preferably, a plurality of air inlet baffles are arranged in an array on one side of the cabinet, and the front and rear sides of the plurality of air inlet baffles are rotatably connected to the cabinet. A collar is provided on one side of each of the plurality of air inlet baffles, and a motor is provided on the top of one side of the inner wall of the cabinet.

[0007] Preferably, the output end of the motor is provided with a first pull rod, the first pull rod has a slide rail, a second pull rod is provided on one side of the air inlet baffle, the top of the second pull rod is adapted to the slide rail of the first pull rod, and one side of the second pull rod is rotatably connected to several collars.

[0008] Preferably, a cooling fan is provided on the other side of the cabinet, and several air outlet baffles are arranged in an array on one side of the cooling fan.

[0009] Preferably, the front and rear sides of several of the air outlet baffles are rotatably connected to the cabinet.

[0010] Preferably, the top of the cabinet is provided with a canopy, and rain collection pipes are provided on the front and rear sides of the bottom of the canopy, with a water inlet pipe provided on one side of the bottom of the two rain collection pipes.

[0011] Preferably, a water tank is provided on one side of the inner wall of the cabinet, and the top of the water tank is fixedly connected to the bottom of the water inlet pipe.

[0012] Preferably, a bracket is fixedly connected to the back of the water tank, and one side of the bracket is fixedly connected to one side of the inner wall of the cabinet.

[0013] Preferably, a water outlet pipe is provided on one side of the water tank. One end of the water outlet pipe is fixedly connected to one side of the water tank, and the other end of the water outlet pipe is provided with several drain heads.

[0014] Preferably, a relay is provided on one side of the front wall of the cabinet, and several heat dissipation fins are provided on the back of the relay, with the drain head adapted to the heat dissipation fins of the relay.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) The photovoltaic energy storage device adopts a mechanical early warning mechanism, which is more reliable than relying on electronic sensors. Through the centrifugal structure design inside the anemometer, when the wind speed reaches the threshold, the slider slides along the inclined groove under the action of centrifugal force, triggering the conduction circuit of the sensing electrode. This mechanical triggering method can automatically judge the arrival of severe weather such as sandstorms without relying on complex electronic sensors, and then control the motor to drive the linkage mechanism to close the air inlet baffle. At the same time, the cooling fan is powered off and the air outlet baffle is automatically attracted by magnetic attraction. This process realizes the fully automatic physical isolation protection of the photovoltaic energy storage device, effectively preventing sand and dust from entering the cabinet and damaging the internal components of the energy storage device. Sand and dust accumulation can also cause poor heat dissipation inside the photovoltaic energy storage device, leading to temperature rise or even short circuit. It is necessary for staff to enter the cabinet to clean the sand and dust, especially in the dead corners where the lines accumulate. Using this device can greatly reduce the frequency of manual maintenance and ensure good heat dissipation conditions inside the photovoltaic energy storage device. (2) The photovoltaic energy storage device adopts an integrated design of rainwater collection and auxiliary water cooling, which closely fits the geographical characteristics of the Northwest region, which is arid, has little rain and frequent sandstorms. This solution is adopted according to local conditions, which not only ensures the sandstorm protection effect, but also avoids the overheating of the photovoltaic energy storage device caused by the suspension of wind cooling. At the same time, since the water cooling auxiliary heat dissipation is an independent temperature control system, even if there is no sandstorm but the cooling fan stops working due to failure, the water cooling auxiliary system can still work normally to ensure the stable operation of the internal unit of the photovoltaic energy storage device, further enhancing the reliability.

[0030] The working principle and usage process of this invention: Active early warning is driven by wind power. Photovoltaic energy storage devices are mostly installed in plains areas with long hours of sunshine and relatively low rainfall, especially in Gobi desert environments. When the wind picks up, the wind force is relatively strong and dust is abundant. When the wind force reaches a certain level, it can easily cause severe weather such as sandstorms. When the natural wind blows the wind cup 301, the wind cup drives the rotating shaft 302 to rotate. Under the action of centrifugal force, as the rotation speed increases, the slider 305 inside the rotating shaft 302 slides along the inclined groove 304. Early warning is triggered: When the wind speed reaches a set threshold (i.e., the rotating shaft speed is high enough), the slider slides to the higher end of the groove. The slider contacts the sensing electrode 306, causing the sensing electrode to emit an electrical signal. This signal is transmitted through the brush 309 to the contact point 310, activating the power supply line 307 circuit and sending an electrical signal to the control system. The system automatically detects the approach of severe weather (such as a sandstorm). Subsequently, the motor 13 begins to rotate counterclockwise, causing the first pull rod 14 to move the second pull rod 15 downwards. This, in turn, causes all the air inlet baffles 2 to rotate and close via the collar 16, simultaneously sending a signal to the cooling fan 9 to de-energize it. Without the wind force from the cooling fan 9, the air outlet baffles 8 naturally droop due to gravity. Because each air outlet baffle has a magnetic attraction device on its inner side, they adhere to each other, providing strong wind resistance. While the cooling fan 9 cannot dissipate heat due to environmental factors, the photovoltaic energy storage device continuously generates photovoltaic power and conducts it to the energy storage cabinet. This process generates a large amount of heat. To prevent overheating of the internal components... Equipped with a water-cooled emergency heat dissipation device, when the temperature of internal components exceeds the threshold, the water tank 6 automatically drains water and sprays it precisely onto the heat dissipation fins of the components through the drain head 12, achieving the effect of emergency heat dissipation. When the wind force decreases and the sandstorm stops, the slider 305 falls back and disconnects the power from the sensing electrode. The sensing electrode then transmits an electrical signal again, causing the motor 13 to rotate clockwise to open the air inlet baffle 2. At the same time, the cooling fan 9 restarts and uses the wind force to flip and open the air outlet baffle 8. Considering the arid and scarce water resources in the northwest region, the top of the cabinet 1 is equipped with a rainwater collection system consisting of a canopy 4 and a rainwater collection pipe 10. When rainfall begins, the power generation of the photovoltaic panel decreases sharply, the heat dissipation demand decreases, and water cooling is not required. The water tank begins to store water. Rainwater flows through the canopy 4 into the rainwater collection pipe 10 and is discharged into the water tank 6 through the water inlet pipe 5 for storage. When a sandstorm occurs again, it can be used for emergency heat dissipation.
