Description

Technical Field

[0001] This invention relates to the field of energy storage technology, specifically to an integrated distributed energy storage system. Background Technology

[0002] Integrated distributed energy storage systems, as highly integrated devices, combine energy storage systems with energy conversion technologies. They not only draw and store electrical energy from the grid or renewable energy generation equipment, but also release the stored energy during peak electricity demand or energy shortages, ensuring the stability and reliability of power supply. This system, also known as an integrated energy storage unit, balances grid load and significantly improves energy utilization efficiency. In existing technologies, to ensure the safe and stable operation of energy storage devices, specialized ventilation and heat dissipation structures are commonly used. These structures effectively dissipate heat generated inside the device through active cooling mechanisms. Specifically, a common design involves installing cooling fans at the device's air outlet, using the fan's rotation to forcibly expel accumulated heat. However, this design has certain drawbacks: if the cooling fan malfunctions or fails during normal operation, the internal heat may not be effectively dissipated in a timely manner, threatening the device's operational safety and stability. Therefore, we propose an integrated distributed energy storage system. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides an integrated distributed energy storage system, comprising an energy storage device body with an air inlet and an air outlet, and a main cooling fan located at the air outlet. During normal operation, the main cooling fan draws out internal gas to form a directional airflow. An auxiliary cooling fan is installed inside the air inlet, initially in standby mode, and automatically activating to maintain heat dissipation when the main cooling fan fails. Both the air inlet and air outlet are equipped with dynamic dustproof components to regulate the opening and closing of airflow channels and intercept particulate matter. The dynamic dustproof components include a U-shaped frame array, composed of multiple equidistant U-shaped frames embedded with dustproof nets. Initially, the U-shaped frame array at the air inlet is parallel and stacked to block dust, while the air outlet is tilted and open. A drive component is provided inside the energy storage device body, connected to the U-shaped frames, to vertically close the U-shaped frame array at the air outlet to prevent foreign objects when the main cooling fan fails, and to tilt and open the air inlet to assist the auxiliary cooling fan in forming a reverse airflow.

[0004] A rectangular plate is fixedly connected to one end of the dustproof net and a sliding rod is fixedly connected to the other end. The sliding rod is slidably connected to the U-shaped frame. A linkage is provided on the U-shaped frame. The sliding rod is connected to the air inlet or air outlet through the linkage. When the U-shaped frame is deflected or tilted, the linkage drives the sliding rod to move along the U-shaped frame, causing the dustproof net to vibrate in coordination with the gas flow to remove attached particles.

[0005] A rectangular frame is rotatably connected to one side of the U-shaped frame. An absorbent sponge is placed inside the rectangular frame. When the U-shaped frame array is kept in a parallel stacked state, multiple rectangular frames are also kept in a parallel stacked state to absorb moisture from the air passing through the dustproof net. Furthermore, a transmission component is provided between the rectangular frame and the sliding rod, which is used to drive the rectangular frame to deflect and unfold relative to the U-shaped frame by moving the sliding rod when the U-shaped frame deflects and tilts, so as to seal the gap between adjacent U-shaped frames.

[0006] The drive assembly includes a shaft 1 fixedly connected to a U-shaped frame, the shaft 1 being rotatably connected to the main body of the energy storage device, a deflection plate fixedly connected to the shaft 1, a shaft 2 fixedly connected to the deflection plate, a connecting rod 1 rotatably connected between multiple shafts 2, a guide rod fixedly connected to the connecting rod 1, and an electric push rod fixedly connected to the main body of the energy storage device. A sliding sleeve is fixedly connected to the extended end of the electric push rod, and one end of the guide rod slides through the sliding sleeve. By activating the electric push rod, multiple shafts 1 are driven to rotate.

[0007] The linkage includes a groove formed on the U-shaped frame. One end of the slide rod is located in the groove and slidably connected to its inner wall. A slide plate is fixedly connected to a section of the slide rod located in the groove. The slide plate is slidably connected to the inner wall of the groove. A shaft is fixedly connected to one end of the slide plate. A fan-shaped plate is fixedly connected to the main body of the energy storage device. A guide groove is formed on the fan plate. One end of the shaft is located in the guide groove and is used to drive the shaft to slide along the guide groove when the U-shaped frame is deflected, so as to drive the slide rod to move relative to the U-shaped frame.

[0008] The guide groove includes an arc-shaped groove formed on the fan-shaped plate, and one end of the shaft is located in the arc-shaped groove and is slidably connected to its inner wall.

[0009] The transmission component includes a connecting plate fixedly connected to a rectangular frame. One end of the connecting plate is rotatably connected to a U-shaped frame via a shaft four, and a shaft five is rotatably connected to the rectangular frame. A connecting rod two is rotatably connected between shaft five and shaft three. Moving shaft three causes the rectangular frame to deflect relative to the U-shaped frame.

[0010] An elastic baffle is fixedly connected between the U-shaped frame and the sliding rod.

[0011] This invention has at least the following beneficial effects: 1. This device achieves high reliability through the collaboration of a main / secondary dual-fan architecture and an intelligent monitoring mechanism. When the main cooling fan fails, the secondary cooling fan can be put into operation in a timely manner to ensure continuous heat dissipation of the main body of the device.

[0012] 2. The design of the dynamic dustproof component in this device enables the air outlet of the main body of the device to maintain a continuous and efficient airflow, while ensuring that the air inlet filters dust in the air in real time.

[0013] 3. This device has a water-absorbing sponge on one side of the dustproof net, which can effectively absorb moisture from the air entering the main body of the device. When the dustproof net is tilted and opened, it causes the water-absorbing sponge to deflect and unfold, thereby sealing the gaps between adjacent U-shaped frames to prevent insects from entering the main body of the device.

[0014] 4. This device supports automatic switching to the auxiliary cooling fan after the main cooling fan has been running for a preset time, and the dust filter status is adjusted in conjunction with the program settings: when the dust filter is switched to the tilt position, the airflow discharged from the main body of the device can simultaneously dry the water-absorbing sponge and perform reverse flushing cleaning on the dust filter.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figures 1-10 The present invention provides a technical solution: an integrated distributed energy storage system, including an energy storage device body 1, an air inlet 11 and an air outlet 12 provided on the energy storage device body 1, and a main cooling fan 2 installed in the air outlet 12. At the same time, an intelligent monitoring mechanism is set in the main cooling fan 2, specifically, a Hall sensor or current sampling module is integrated in the motor control circuit of the main cooling fan 2 to monitor the fan speed or operating current in real time. If the speed is lower than the threshold or the current is abnormal, such as a surge in stall current, the main cooling fan 2 is determined to be faulty or ineffective. The main cooling fan 2 is configured to actively extract the gas inside the energy storage device body 1 to form a directional airflow under normal operating conditions. The auxiliary cooling fan 3 is installed inside the air inlet 11 and is initially in standby mode. When the main cooling fan 2 fails, it is automatically started by program control to draw gas from the inside of the energy storage device body 1 through the air inlet 11 to maintain the heat dissipation function. Specifically, through the synergy of the main / auxiliary dual fan architecture and the intelligent monitoring mechanism, high reliability is ensured. When the main cooling fan 2 fails, the auxiliary cooling fan 3 can be put into operation in time to ensure continuous heat dissipation of the device body. Dynamic dustproof components 4 are respectively disposed in the air inlet 11 and the air outlet 12, and are used to adjust the opening and closing state of the airflow channel and intercept particulate matter during heat dissipation. Dynamic dustproof components 4 include: The U-shaped frame array 5 is composed of multiple U-shaped frames 6 arranged at equal intervals. Each U-shaped frame 6 is embedded with a dustproof net 7. In the initial state, the U-shaped frame array 5 at the air inlet 11 is kept in a parallel and overlapping state to block the air inlet 11 and reduce the entry of dust. The U-shaped frame array 5 at the air outlet 12 is kept in an inclined and open state to form the maximum ventilation cross-sectional area. The top surface of the U-shaped frame 6 is made of rubber material to provide a certain deformation capacity for the contact section between the U-shaped frame 6 and the rectangular frame 16 when the rectangular frame 16 is deflected, so as to avoid interference. The drive component 8 is connected to the U-shaped frame 6. When the main cooling fan 2 fails, the U-shaped frame array 5 at the air outlet 12 is synchronously rotated to a vertically closed state under the action of the drive component 8 to seal the air outlet 12 to prevent the intrusion of external foreign objects. Meanwhile, the U-shaped frame array 5 at the air inlet 11 is synchronously deflected to an inclined open state to assist the auxiliary cooling unit in forming a reverse airflow. The design of the dynamic dustproof component 4 in this device enables the air outlet of the main body of the device to maintain a continuous and efficient airflow, while ensuring that the air inlet filters the dust in the air in real time. Meanwhile, the device has a water-absorbing sponge 17 on one side of the dustproof net 7, which can effectively absorb the moisture in the air entering the main body of the device. When the dustproof net 7 is tilted and opened, the water-absorbing sponge 17 is deflected and unfolded to seal the gap between the adjacent U-shaped frames 6, so as to prevent insects from entering the main body of the device. This device supports automatic switching to the auxiliary cooling fan 3 after the main cooling fan 2 has been running for a preset time, through program settings. At the same time, the state of the dust filter 7 and the water-absorbing sponge 17 are adjusted in conjunction: when the water-absorbing sponge 17 deflects away from the dust filter 7, and when the dust filter 7 is switched to an inclined position, the airflow discharged from the main body of the device can simultaneously dry the water-absorbing sponge 17 and perform reverse flushing and cleaning of the dust filter 7.

[0019] A rectangular plate 13 is fixedly connected to one end of the dustproof net 7 and the U-shaped frame 6, and a sliding rod 14 is fixedly connected to the other end. The sliding rod 14 is slidably connected to the U-shaped frame 6. A linkage 15 is provided on the U-shaped frame 6. The sliding rod 14 is connected to the air inlet 11 or the air outlet 12 through the linkage 15. When the U-shaped frame 6 is tilted, the linkage 15 converts the rotational motion of the U-shaped frame 6 into the linear motion of the sliding rod 14, driving the sliding rod 14 to slide along the U-shaped frame 6. During the movement of the sliding rod 14, the dustproof net 7 vibrates, and at the same time, the dustproof net 7 deforms to peel off the attached particles, thereby enhancing the backwash cleaning effect of the airflow on the dustproof net 7.

[0020] A rectangular frame 16 is rotatably connected to one side of the U-shaped frame 6. An absorbent sponge 17 is installed inside the rectangular frame 16. When the U-shaped frame array 5 is kept in a parallel stacked state, the multiple rectangular frames 16 are also kept in a parallel stacked state to absorb the moisture in the air passing through the dustproof net 7. Furthermore, a transmission component 18 is provided between the rectangular frame 16 and the sliding rod 14. When the U-shaped frame 6 is tilted, the sliding rod 14 moves to drive the rectangular frame 16 to tilt and unfold relative to the U-shaped frame 6, thereby sealing the gap between adjacent U-shaped frames 6 to prevent insects from entering the main body of the device. At the same time, the overlapping state of the dustproof net 7 and the water-absorbing sponge 17 is unfolded to avoid the large resistance to the gas when the two overlap, thereby reducing the cleaning effect of the flowing gas on the dustproof net 7 and the drying effect on the water-absorbing sponge 17.

[0021] The drive assembly 8 includes a shaft 19 fixedly connected to the U-shaped frame 6. The shaft 19 located in the air inlet 11 is rotatably connected to the air inlet 11, and the shaft 19 located in the air outlet 12 is rotatably connected to the air outlet 12. A deflection plate 21 is fixedly connected to the shaft 19, and a shaft 22 is fixedly connected to the deflection plate 21. A connecting rod 23 is rotatably connected between multiple shafts 22. A guide rod 24 is fixedly connected to the connecting rod 23, and an electric push rod 25 is fixedly connected to the main body 1 of the energy storage device. A sliding sleeve 26 is fixedly connected to the extended end of the electric push rod 25. One end of the guide rod 24 slides through the sliding sleeve 26. When the electric push rod 25 is activated, it drives the sliding sleeve 26 to move, which in turn drives the connecting rod 23 fixedly connected to the guide rod 24 to move, thereby causing the deflection plate 21 to deflect, and in turn causing multiple shafts 19 to rotate.

[0022] The linkage 15 includes a groove 27 formed on the U-shaped frame 6. One end of the slide rod 14 is located in the groove 27 and is slidably connected to its inner wall. A slide plate 28 is fixedly connected to a section of the slide rod 14 located in the groove 27. The slide plate 28 is slidably connected to the inner wall of the groove 27. A shaft 29 is fixedly connected to one end of the slide plate 28. A sector plate 31 is fixedly connected to the main body 1 of the energy storage device. A guide groove 32 is formed on the sector plate 31. The guide groove 32 includes an arc groove 33 formed on the sector plate 31. One end of the shaft 29 is located in the arc groove 33 and is slidably connected to its inner wall. When the U-shaped frame 6 is deflected, the shaft 29 is driven to slide along the arc groove 33, thereby driving the shaft 29 to move relative to the U-shaped frame 6, thereby driving the slide rod 14 to move relative to the U-shaped frame 6.

[0023] The transmission component 18 includes a connecting plate 34 fixedly connected to the rectangular frame 16. One end of the connecting plate 34 is rotatably connected to the U-shaped frame 6 via a shaft 35, and the rectangular frame 16 is rotatably connected to a shaft 36. A connecting rod 37 is rotatably connected between the shaft 36 and the shaft 29. When the shaft 29 is moved, the connecting rod 37 drives the rectangular frame 16 to deflect relative to the U-shaped frame 6.

[0024] An elastic baffle 38 is fixedly connected between the U-shaped frame 6 and the slide rod 14 to dynamically seal the gap between the slide rod 14 and the U-shaped frame 6, so as to prevent insects from entering the main body of the device.
