Description

Technical Field

[0001] This invention relates to the field of energy storage equipment technology, and in particular to an intelligent combined photovoltaic power generation energy storage cabinet. Background Technology

[0002] With the development of new energy technologies, photovoltaic power generation, with its core advantages of being clean and pollution-free, renewable, and widely distributed, has become a key pillar in the global energy structure transformation. Its application scenarios have gradually expanded from large-scale centralized outdoor power plants to diversified fields such as industrial and commercial parks and residential distributed photovoltaic systems. In this process, photovoltaic power generation energy storage cabinets, as core equipment for energy storage and dispatch, directly determine the overall operating efficiency and safety level of the photovoltaic power generation system through their performance stability, ease of operation and maintenance, and environmental adaptability.

[0003] Currently, the industry has begun research on the structural optimization of photovoltaic power generation energy storage cabinets. For example, Chinese patent CN117254196B discloses a self-controlled energy storage combined cabinet, including a cabinet base, with multiple enclosed energy storage battery cabinets arranged sequentially along the base. The energy storage battery cabinets are positioned and fixed to the cabinet base by a positioning and connecting mechanism. The positioning and connecting mechanism includes an air inlet duct and an air return duct, which are connected to an air-cooled circulation processor. The energy storage battery cabinets are separated by upper and lower partitions. The system includes multi-layered energy storage battery compartments, each with a closed frame surrounding the battery. Temperature and smoke sensors are installed within the frame. Ventilation holes are located on the horizontally opposite side panels of the frame. Air inlet and outlet channels are provided between the side panels with ventilation holes and the side walls of the energy storage battery cabinet. Movable sealing plates are installed opposite the side panels. This system employs a closed structure with interlocking snap-fit ​​connections, making the cabinet dustproof, rodent-proof, and easy to install.

[0004] The aforementioned energy storage battery cabinet connects the frame with the air inlet and outlet channels through ventilation holes, enabling ventilation and cooling of the energy storage batteries within the frame. However, during the charging and discharging process, the energy storage batteries exhibit significant localized heat generation. The aforementioned ventilation and cooling method can only achieve overall airflow within the partition and cannot create a directional and enhanced cooling airflow for the areas where heat is concentrated. As a result, localized high temperatures cannot be dissipated in time. When the energy storage batteries operate at high temperatures, it not only accelerates the capacity decay of the energy storage batteries and reduces their lifespan but may also trigger thermal runaway risks, posing safety hazards.

[0029] Example 1:

[0030] This invention provides an intelligent modular photovoltaic power generation and energy storage cabinet, such as... Figures 1-6As shown, it includes: an inner cabinet 1, an inner cabinet door 2 hinged to the front of the inner cabinet 1, a support frame 3 slidably installed inside the inner cabinet 1, an energy storage battery 4 installed on the support frame 3, and heat dissipation components symmetrically installed on the upper and lower inner walls of the inner cabinet 1. The heat dissipation components include a fixed seat 5, which is fixedly connected to the inner wall of the inner cabinet 1. A rotating groove is provided on the side of the fixed seat 5 near the energy storage battery 4, and a ball bearing 6 is rotatably installed in the rotating groove. The inner wall of the rotating groove is adapted to the outer wall of the ball bearing 6. An air outlet pipe 7 is fixedly installed on the side of the ball bearing 6 near the energy storage battery 4. The end of the air outlet pipe 7 near the ball bearing 6 is connected to the output end of the air cooler 8. An adjustment frame 9 is provided outside the air outlet pipe 7. Moving columns 10 are symmetrically arranged on the left and right sides of the adjustment frame 9. An electric push rod 11 and a controller are provided on the inner wall of the inner cabinet 1. The electric push rod 11 is electrically connected to the controller. A connecting plate 12 is provided at the output end of the electric push rod 11. The end of the connecting plate 12 away from the electric push rod 11 is connected to the moving column 10.

[0031] The center line connecting the two fixed seats 5 is on the same straight line as the central axis of the inner cabinet 1;

[0032] A flow divider plate 13 is provided at the end of the air outlet pipe 7 away from the ball bearing 6. A cavity is provided inside the flow divider plate 13. The interior of the air outlet pipe 7 is connected to the cavity. Several flow divider holes are provided at the bottom of the flow divider plate 13. One end of the flow divider hole is connected to the cavity, and the other end of the flow divider hole is connected to the outside of the flow divider plate 13.

[0033] Diverting holes are equally spaced along the length of the diverting plate 13, and nozzles 14 are installed at the diverting holes, with the output end of the nozzles 14 facing the energy storage battery 4.

[0034] The support frame 3 includes a rear baffle 15, a support frame 16 and two side plates 17. The outer wall of the side plate 17 is slidably connected to the inner wall of the inner cabinet 1. The left and right sides of the rear baffle 15 are respectively connected to the rear end of the side plate 17. The support frame 16 is horizontally arranged between the two side plates 17. The left and right sides of the support frame 16 are respectively fixedly connected to the inner walls of the left and right side plates 17.

[0035] The supporting frame 16 has a rectangular frame structure;

[0036] Two second temperature sensors 22 are installed on the inner wall of the side panel 17. The two second temperature sensors 22 are symmetrically arranged on the upper and lower sides of the energy storage battery 4. The second temperature sensors 22 are used to detect the temperature inside the inner cabinet 1. The second temperature sensors 22 are electrically connected to the controller.

[0037] Several spring rods 23 are installed on the outside of the vent pipe 7. One end of the spring rod 23 is hinged to the inner wall of the inner cabinet 1, and the other end of the spring rod 23 is hinged to the outer wall of the vent pipe 7. The several spring rods 23 are arranged in a ring array about the center line of the vent pipe 7.

[0038] The working principle and beneficial effects of the above technical solution are as follows: During the operation of the energy storage battery 4, the second temperature sensor 22 installed on the inner wall of the side plate 17 can detect the temperature inside the inner cabinet 1. There are two sensors installed on the side plate 17. Therefore, the second temperature sensor 22 can detect the temperature of the upper left, lower left, upper right, and lower right of the energy storage battery 4 respectively. When the temperature difference between the inner cabinet 1 detected by the four second temperature sensors 22 does not exceed 5°C, the electric push rod 11 remains in its initial state, and the air outlet pipe 7 is in a vertical state. At this time, the cooling gas output by the air cooler 8 can flow into the cavity of the diverter plate 13 through the air outlet pipe 7. After being evenly distributed in the cavity, multiple vertically ejected airflows are formed by the diverter holes and nozzles 14 evenly spaced at the bottom of the diverter plate 13. Then, it sprays vertically onto the surface of the energy storage battery 4, and then flows along the surface of the energy storage battery 4, thereby cooling the energy storage battery 4; when the temperature difference between the temperatures detected by the four second temperature sensors 22 inside the inner cabinet 1 exceeds 5°C, the second temperature sensors 22 convert the temperature signal into an electrical signal and transmit it to the controller. The controller compares the detection values ​​of the two upper second temperature sensors 22 and the detection values ​​of the two lower second temperature sensors 22, and obtains the side with the higher temperature. If the upper right temperature is higher than the upper left temperature, the controller controls the upper electric push rod 11 to extend to the right. The electric push rod 11 drives the moving column 10 to move to the right through the connecting plate 12. The moving column 10 drives the adjustment frame 9 of the rectangular frame structure to move to the right. When the adjustment... When the adjusting frame 9 contacts the outer wall of the exhaust pipe 7, the adjusting frame 9 can drive the exhaust pipe 7 to rotate around the ball bearing 6 as the center, thereby changing the tilt angle of the exhaust pipe 7. This causes the output end of the exhaust pipe 7 to rotate towards the upper right of the energy storage battery 4, and the nozzle 14 to be aimed at the upper right of the energy storage battery 4. The cooling airflow generated by the air cooler 8 can then be sprayed towards the upper right of the energy storage battery 4, thereby forming a directional cooling airflow on the upper right of the energy storage battery 4, quickly cooling the energy storage battery 4 locally and improving cooling efficiency. If the temperature in the lower right is higher than that in the lower left, the controller controls the electric push rod 11 on the lower side to extend to the right, causing the output end of the exhaust pipe 7 to rotate towards the right side of the energy storage battery 4, thereby concentrating cooling on the lower right of the energy storage battery 4, improving the cooling effect and avoiding localized cooling. The heat accumulation caused by insufficient airflow can control the local maximum temperature of the energy storage battery 4 below 36°C, effectively reducing the risk of thermal runaway and extending the service life of the energy storage battery 4. When the exhaust pipe 7 rotates, the spring rod 23 outside the exhaust pipe 7 will adaptively extend and retract with the rotation of the exhaust pipe 7. At least four spring rods 23 are provided. By setting multiple spring rods 23, on the one hand, they can play a supporting and stabilizing role, improving the vibration resistance of the exhaust pipe 7. Even in strong winds or equipment vibration scenarios outdoors, the stability of the heat dissipation structure can still be maintained. On the other hand, it avoids structural deformation caused by frequent rotation of the exhaust pipe 7. Finally, it can achieve precise adjustment of the orientation of the nozzle 14 on the diverter plate 13, ensuring that the cooling airflow is directly aimed at the local area with abnormal temperature.When the energy storage battery 4 needs maintenance or replacement, the operator can directly pull the sliding support frame 3 in the inner cabinet 1. The support frame 3, through the sliding engagement between the outer wall of the side plate 17 and the inner wall of the inner cabinet 1, allows the inner cabinet 1 to be pulled out entirely in the front-to-back direction. The support frame 16 provides stable support for the energy storage battery 4, and the rear baffle 15 acts as a limiting and protective element, ensuring that the battery will not slip backward due to inertia during extraction. After maintenance, simply push the support frame 3 back to its original position along the inner wall to quickly restore equipment operation, achieving rapid assembly of the support frame 3 and the inner cabinet 1.

[0039] Example 2:

[0040] Based on the above embodiment 1, as follows Figure 1 , Figure 5 As shown, it also includes an outer cabinet 18, with multiple inner cabinets 1 stacked inside the outer cabinet 18. An outer cabinet door 19 is provided on the front of the outer cabinet 18, and one side of the outer cabinet door 19 is hinged to the outer cabinet 18.

[0041] The air-cooled unit 8 is fixedly installed outside the outer cabinet 18;

[0042] Multiple exhaust vents and air inlets are provided on the side wall of the outer cabinet 18. A negative pressure fan 20 is installed in the exhaust vent, and the negative pressure fan 20 is electrically connected to the controller. A first dustproof net 21 is installed in the air inlet.

[0043] A first temperature sensor is installed on the inner wall of the top of the outer cabinet 18. The first temperature sensor is used to detect the temperature inside the outer cabinet 18 and is electrically connected to the controller.

[0044] The working principle and beneficial effects of the above technical solution are as follows: A first temperature sensor on the inner wall of the top of the outer cabinet 18 monitors the temperature change of the interlayer space between the outer cabinet 18 and the inner cabinet 1 in real time. When the temperature inside the outer cabinet 18 detected by the first temperature sensor is greater than the preset temperature (preset temperature greater than 40℃), the controller controls the negative pressure fan 20 to increase its speed to 1500-2000 r / min. Through the negative pressure effect, the air circulation between the outer cabinet 18 and the outside is accelerated, quickly removing the accumulated heat in the interlayer space. When the temperature inside the outer cabinet 18 is lower than 35℃, the controller controls the negative pressure fan 20 to decrease its speed to 800-1000 r / min, ensuring daily heat dissipation. At the same time, it can reduce energy consumption and improve the intelligence level of the energy storage cabinet. In the above solution, the inner cabinet 1 solves the problem of local heat accumulation of the energy storage battery 4 by adjusting the tilt angle of the air outlet pipe 7. The outer cabinet 18 solves the problem of overall heat accumulation caused by stacking multiple inner cabinets 1 by cooperating with the first temperature sensor and the negative pressure fan 20. By setting the outer cabinet 18, the first temperature sensor and the negative pressure fan 20, the problem of "secondary heating" caused by the heat accumulation of the inner cabinet 1 can be avoided. It is especially suitable for the needs of centralized deployment of multiple modules in industrial and commercial scenarios. In addition, the outer cabinet 18 has a protective function for the inner cabinet 1, which further extends the service life of the energy storage battery 4 inside the inner cabinet 1.

[0045] Example 3:

[0046] Based on Example 1 or 2, such as Figures 1-4 As shown, the side panel 17 has a first air vent 24 corresponding to the moving column 10 on its side wall, and the inner cabinet 1 has a second air vent 25 corresponding to the first air vent 24 on its side wall. The diameter of the first air vent 24 is larger than the diameter of the second air vent 25, and a second dustproof net 26 is installed inside the second air vent 25.

[0047] The working principle and beneficial effects of the above technical solution are as follows: the cooling gas ejected from the nozzle 14 flows into the first vent 24 after passing through the surface of the energy storage battery 4, and then flows into the second vent 25 through the first vent 24. Finally, it flows out of the inner cabinet 1 through the second dustproof net 26. The diameter of the first vent 24 is larger than that of the second vent 25. After the hot airflow converges at the first vent 24, the flow rate increases when it passes through the smaller diameter second vent 25, which avoids the hot airflow from lingering inside the inner cabinet 1 and ensures that the hot airflow after heat dissipation quickly leaves the area around the energy storage battery 4, thereby improving the cooling effect.

[0048] Example 4:

[0049] Based on Example 3, such as Figures 1-4As shown, a sliding hole 27 is provided at one end of the movable column 10 near the first vent 24. A sliding column 28 is slidably disposed in the sliding hole 27. One end of the sliding column 28 is connected to the inner wall of the sliding hole 27 through a connecting spring 29. The other end of the sliding column 28 extends into the first vent 24 and is provided with a blocking block 30. The diameter of the blocking block 30 is smaller than the diameter of the first vent 24. The end of the blocking block 30 away from the sliding column 28 has a cone-shaped structure.

[0050] The working principle and beneficial effects of the above technical solution are as follows: If the temperature at the upper right is higher than that at the upper left, the controller controls the electric push rod 11 on the upper side to extend to the right. The electric push rod 11 drives the moving column 10 to move to the right through the connecting plate 12. The moving column 10 drives the adjusting frame 9 of the rectangular frame structure to move to the right. When the adjusting frame 9 drives the air outlet pipe 7 to adjust its angle so that the nozzle 14 is aligned with the upper right of the energy storage battery 4, the cooling airflow generated by the air cooler 8 can be sprayed towards the upper right of the energy storage battery 4. At the same time, the moving column 10 on the right can drive the sliding column 28 to move into the second air outlet 25. The sliding column 28 drives the blocking block 30 into the second air outlet 25 on the right, thereby blocking the second air outlet 25 on the right. The cooling airflow sprayed towards the upper right of the energy storage battery 4 cannot be discharged from the second air outlet 25 on the right. The cooling airflow then flows towards the second air outlet 25 on the left and flows from right to left along the surface of the energy storage battery 4, further carrying away the heat on the upper surface of the energy storage battery 4. The block 30 blocks the second vent 25. If the electric push rod 11 is still extending to the right, the block 30 slides inside the second vent 25 on the right side, quickly pushing out the residual gas inside the second vent 25 on the right side. During the pushing process, the second dustproof net 26 is cleaned. When the end of the block 30 contacts the second dustproof net 26, it can also vibrate the second dustproof net 26 by tapping, causing the dust attached to the second dustproof net 26 to fall off, realizing automatic cleaning of the second dustproof net 26, avoiding blockage of the second dustproof net 26, and extending the service life of the second dustproof net 26. When the second vent 25 on the left side is blocked by the block 30 on the left side, the block 30 on the right side separates from the second vent 25 on the right side, and the airflow can flow into the second vent 25 on the right side. The airflow can quickly pass through the second dustproof net 26, thereby increasing the airflow circulation speed and further improving the cooling effect on the energy storage battery 4.

[0051] Example 5:

[0052] Based on Example 4, such as Figures 1-4 As shown, sliding grooves 31 are symmetrically arranged on the upper and lower sides of the movable column 10. A slider 32 is slidably arranged in the sliding groove 31. The slider 32 is connected to the inner wall of one end of the sliding groove 31 by a compression spring 33. A sealing plate 34 is arranged at the end of the slider 32 away from the movable column 10. The area of ​​the two sealing plates 34 is greater than the cross-sectional area of ​​the end of the first air outlet 24 away from the second air outlet 25.

[0053] The working principle and beneficial effects of the above technical solution are as follows: When the moving column 10 moves toward the first air outlet 24, the sealing plate 34 can contact the outer wall of the side plate 17. As the moving column 10 moves, the slider 32 slides in the slide groove 31, and the compression spring 33 is gradually compressed, thereby increasing the pressure of the sealing plate 34 on the side plate 17. The sealing plate 34 can seal the first air outlet 24, reduce the outflow of cooling gas from this side, and at the same time accelerate the flow of cooling gas to the other side, thus improving the cooling effect.
