Description

Technical Field

[0001] This invention belongs to the field of container energy storage technology, specifically a cooling and insulation system and control method for container energy storage. Background Technology

[0002] With the rapid development of new energy technologies, energy storage technology has become crucial for solving the problem of energy storage and supply-demand balance. Containerized energy storage, with its advantages of modularity, high mobility, and convenient installation, is widely used in various fields such as grid peak shaving, distributed energy systems, and emergency power supplies. However, during the operation of containerized energy storage systems, the battery packs generate a large amount of heat. If heat dissipation is not timely or efficient, it will seriously affect battery performance and lifespan, and may even lead to safety risks. At the same time, in cold environments, the battery packs lack effective insulation measures, making them prone to performance degradation due to excessively low temperatures.

[0003] Therefore, the present invention provides a cooling and insulation system and control method for container energy storage, which improves the above-mentioned technical problems. Summary of the Invention

[0004] This invention aims to address the shortcomings of existing technologies by providing a cooling and insulation system and control method for containerized energy storage. The invention adopts a design that combines a double-layer container, an air exchange component, a heating component, an air guiding component, and a dust filter cleaning component. The ambient temperature is monitored in real time by a temperature sensor, and the control unit automatically switches between heat dissipation and insulation modes to achieve precise temperature control of the battery pack and automatic cleaning of the dust filter. This ensures that the battery pack operates stably at a suitable temperature and solves the problems of poor heat dissipation and insulation, easy clogging of the dust filter, and high maintenance costs in traditional systems.

The ventilation components include: ventilation boxes symmetrically arranged on the upper sides of the inner box, and ventilation fans are installed on one side of the ventilation boxes. An air guiding assembly for connecting the inner chamber and the ventilation box includes: an air guiding pipe and a support plate; the support plate is fixed to the lower part of the inner chamber, and the mounting bracket is mounted on top of the support plate; a cavity is formed between the support plate and the bottom of the inner chamber, and an air hole is provided; the air guiding pipe is installed on one side of the ventilation box, with one end connected to the ventilation box and the other end connected to the cavity; the ventilation box is provided with a through groove that communicates with the inner cavity of the inner chamber; The ventilation box is equipped with a heating element.

[0006] Preferably, the ventilation fan consists of a cylinder, a fan, and a drive motor. The fan is rotatably mounted in the middle of the cylinder via a bracket. The drive motor is fixed to the bracket to drive the fan to rotate. The cylinder is fixed to the side wall of the ventilation box away from the inner box. A dust filter is provided on the side of the cylinder away from the inner box, and a cleaning component is provided on the outer side of the dust filter.

[0007] Preferably, the cleaning component includes a mounting plate arranged parallel to the outside of the dust filter, and bristles are fixed on the side of the mounting plate facing the dust filter, the bristles being in contact with the outer wall of the dust filter.

[0008] Preferably, the cylinder is provided with a driving assembly for driving the cleaning assembly to rotate. The driving assembly includes: a fixed sleeve fixed to the outer wall of the cylinder; a rotating ring rotatably mounted on the side of the fixed sleeve; the rotating ring is sleeved on the cylinder and rotatably connected to the outer surface of the cylinder; connecting rods are symmetrically fixed on the outer wall of the rotating ring; the connecting rods consist of a fixed rod and a movable rod; one end of the connecting rod is connected to a mounting plate, and the other end is fixed with a magnetic block one; a limiting ring rail is fixed on the inner wall of the cylinder at a position corresponding to the magnetic block one; a magnetic block two is movably mounted in the middle of the limiting ring rail; the magnetic block one and the magnetic block two attract each other; a connecting column is coaxially fixed in the middle of the fan; a lever is fixed on the side wall of the connecting column; and a movable plate is movably mounted on the side of the magnetic block two facing the middle of the cylinder via a torsion spring.

[0009] Preferably, the dust filter is formed by a combination of an installation ring and a middle filter. Multiple limiting posts are fixed on the side of the cylinder away from the inner box. The installation ring of the dust filter has mounting holes at positions corresponding to the limiting posts, and the limiting posts are inserted into the mounting holes.

[0010] Preferably, the connecting rod consists of a fixed rod and a movable rod. The fixed rod is fixed to the outer wall of the rotating ring, and the movable rod is fixed to the side wall of the mounting plate. The end of the movable rod away from the mounting plate is slidably and elastically connected to the fixed rod.

[0011] Preferably, the mounting plate has limit rods fixed at both ends facing the dust filter screen, and the ends of the limit rods are rotatably mounted with ball bearings, which fit against the outer wall of the mounting ring of the dust filter screen.

[0012] Preferably, a drive rod is slidably mounted on the movable rods on both sides. The drive rod is designed in an η-shape. Both the short and long sections of the drive rod slide through the through holes opened on the movable rod. An arc-shaped block is fixed to the side of the fixed sleeve facing the mounting plate. The arc-shaped block corresponds to the short section of the drive rod. The long section of the drive rod slides through the through hole opened on the limiting rod, and a horizontal plate is fixed to its end. Cleaning rods are symmetrically fixed to the side walls of the horizontal plate. Horizontal bars are fixed to the opposite side walls of the cleaning rods on both sides. The cleaning rods and horizontal bars are movably inserted into the bristles.

[0013] Preferably, a collection trough for collecting impurities is provided below the ventilation box, and a locking block is symmetrically fixed at both ends of the collection trough. A locking groove is symmetrically fixed at both ends of the bottom of the ventilation box, and the locking block is slidably inserted into the locking groove.

[0014] A control method for a containerized energy storage cooling and insulation system, the method employing the aforementioned containerized energy storage cooling and insulation system, includes the following steps: S1. After the system starts, the control unit first performs a self-test to confirm that all components are in normal condition. Then, it continuously monitors the ambient temperature inside and outside the inner box through sensors. S2. The control unit compares the real-time monitoring data with the preset temperature threshold and automatically determines the working mode: if the internal temperature is higher than the upper threshold, it enters the heat dissipation mode; if the internal temperature is lower than the lower threshold, it enters the heat preservation mode. When the S3 cooling mode is activated, the rain shields on both sides of the outer casing are open, and the ventilation fans on both sides of the inner casing start up quickly. The right ventilation fan draws in cold air from outside, filters it, and then sends it evenly into the battery pack from the bottom through the air duct. At the same time, the left ventilation fan exhausts the hot air inside the casing, forming a smooth cooling cycle. S4. When the heat preservation mode is activated, the right rain shield opens, the left rain shield and the left ventilation fan close. The heating element and the ventilation fan work together. The cold air drawn in by the right ventilation fan is quickly heated to a suitable temperature when it passes through the heating element, and then sent into the battery pack area through the air duct to provide heat to the battery pack and prevent the temperature from getting too low. S5. During the operation of the ventilation fan, the reverse rotation of the ventilation fan will drive the cleaning component through the drive component, so that the bristles will rotate automatically and clean the dust filter, maintaining smooth ventilation.

[0015] The beneficial effects of this invention are as follows: Firstly, this invention achieves precise adaptive temperature control. By linking the temperature sensor with the control unit, it automatically switches between heat dissipation and heat preservation modes to ensure that the battery pack is always in a suitable temperature environment. This effectively avoids the problems of high temperature affecting performance and lifespan, and low temperature causing performance degradation, thus ensuring the stable operation of the battery pack.

[0016] Secondly, the invention significantly improves heat dissipation and heat preservation efficiency. The double-layer box combined with the heat preservation layer reduces external temperature interference. The air guide component achieves uniform airflow coverage of the battery pack through the air holes of the support plate. During cooling, cold air is evenly delivered from the bottom, and during heat preservation, hot air is precisely delivered, resulting in a more balanced temperature control effect.

[0017] Thirdly, the dust filter of this invention achieves automated cleaning. By using the reverse rotation of the ventilation fan to drive the cleaning component, the dust filter is prevented from clogging and ventilation is kept smooth through the dual action of brush rotation and airflow back blowing. It does not require frequent manual cleaning, thus reducing maintenance costs and manpower input.

[0018] Fourth, the present invention enhances stability and durability. The dust filter is securely installed through the limiting post. The elastic connection of the cleaning components and the ball bearing design of the limiting rod reduce component wear. The collection tank efficiently collects and cleans impurities, extends the service life of each component, and reduces the risk of pipeline leakage and component damage.

[0019] Fifth, the present invention is easy to install and maintain and has a wide range of applications. The plug-in installation of the dust filter and the snap-fit ​​design of the collection tank make it easy to disassemble and replace. The system structure has a high degree of modularity and is compatible with energy storage equipment of different specifications. It can be applied to multiple scenarios such as grid peak shaving and distributed energy systems. Attached Figure Description

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0026] Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0027] Example 1: As Figures 1 to 10 As shown, a cooling and insulation system for container energy storage according to an embodiment of the present invention includes: The energy storage container consists of an outer box 1 and an inner box 4 located inside; the outer box 1 is hinged to both ends with a door 2, and the door 2 is provided with a ventilation slot 3; the inner box 4 is provided with a mounting frame 11, and a battery pack 12 is arranged on the mounting frame 11. The ventilation assembly includes ventilation boxes 5 symmetrically arranged above both ends of the inner box 4, and ventilation fans 6 are installed on both sides of the ventilation boxes 5. The air guiding assembly includes an air guiding pipe 8 and a support plate 9; the support plate 9 is fixed to the lower part of the inner box 4, and the mounting bracket 11 is located above the support plate 9; air holes 10 are evenly distributed on the support plate 9, and a cavity is formed between it and the bottom of the inner box 4; the air guiding pipe 8 is connected to the bottom of one side of the air exchange box 5, and communicates with the inner cavity of the air exchange box 5 and the bottom cavity of the support plate 9 respectively; the back of the other side of the air exchange box 5 is provided with a through groove 7 that communicates with the inner cavity of the inner box 4; Heating element 13 is installed inside air exchange box 5 which is equipped with air duct 8; The containerized energy storage system is equipped with a control unit and a temperature sensor. When the system is started, the control unit quickly performs a self-check process to ensure that all components are in normal working condition. Then, the high-precision sensor monitors the ambient temperature inside and outside the container in real time and accurately. After receiving this monitoring data, the control unit immediately compares it with the preset temperature threshold to intelligently determine the current working mode to be adopted. If the internal temperature is detected to rise above the upper limit threshold, the system will automatically switch to heat dissipation mode. In this mode, the rain shields on both sides are open, and the ventilation fans 6 on both sides start quickly. The right ventilation fan 6 efficiently draws in the cool air from outside and delivers it to the bottom cavity of the housing 4 through the air duct 8. Then, it passes through the air hole 10 and is evenly delivered from the bottom of the battery pack 12 to provide comprehensive and effective cooling for the battery pack 12. The left ventilation fan 6 exhausts the hot air inside the housing 4, forming a smooth heat dissipation cycle to ensure that the battery pack 12 operates stably in a suitable temperature environment. Conversely, if the internal temperature is detected to drop below the lower threshold, the system will automatically enter the heat preservation mode. In the heat preservation mode, the right rain shield is opened, the left rain shield and the left ventilation fan 6 are closed, and the heating element 13 (which can be a mature heating element such as an electric heating wire or a PTC ceramic heating plate) works in conjunction with the ventilation fan 6. The cold air drawn in by the right ventilation fan 6 is rapidly heated to a suitable temperature when it passes through the heating element 13, and then sent into the battery pack 12 area through the air guide pipe 8 to provide the necessary heat to the battery pack 12, effectively preventing performance degradation or damage caused by excessively low temperature. Furthermore, by setting up an outer casing 1 and an inner casing 4, both of which have insulation layers on their side walls, this double-layer casing structure, combined with the insulation layer design, can effectively reduce the impact of external ambient temperature on the internal battery pack 12. Whether in high or low temperature environments, it can create a relatively stable temperature space for the battery pack 12, further improving the system's heat preservation and cooling effects. At the same time, the hinged doors 2 at both ends of the outer casing 1 facilitate the inspection and maintenance of the internal battery pack 12. Ventilation slots 3 are provided on the doors 2, and rain guards are rotatably installed on the outer wall of the ventilation slots 3 to prevent rainwater from entering. In addition, there is a space reserved between the two ends of the outer casing 1 and the inner casing 4 to ensure the distance between the ventilation fan 6 and the ventilation slots 3. In rainy weather, this can effectively prevent rainwater from splashing into the ventilation fan 6 through the ventilation slots 3, further enhancing the rainproof effect.

[0028] like Figures 5 to 10 As shown, the ventilation fan 6 consists of a cylinder 15, a fan 16 and a drive motor. The fan 16 is rotatably mounted in the middle of the cylinder 15 via a bracket. The drive motor is fixed on the bracket to drive the fan 16 to rotate. The cylinder 15 is fixed on the side wall of the ventilation box 5 away from the inner box 4. A dust filter 24 is provided on the side of the cylinder 15 away from the inner box 4. A cleaning component is provided on the outer side of the dust filter 24. The cleaning assembly includes a mounting plate 22 arranged parallel to the outside of the dust filter 24. Brush bristles 23 are fixed on the side of the mounting plate 22 facing the dust filter 24, and the brush bristles 23 are in contact with the outer wall of the dust filter 24. A drive assembly is provided on the cylinder 15 to drive the cleaning assembly to rotate. The drive assembly includes a fixed sleeve 27 fixed to the outer wall of the cylinder 15. A rotating ring 26 is rotatably installed on the side of the fixed sleeve 27. The rotating ring 26 is sleeved on the cylinder 15 and rotatably connected to the outer surface of the cylinder 15. A connecting rod is symmetrically fixed on the outer wall of the rotating ring 26. The connecting rod consists of a fixed rod 25 and a movable rod 29. One end of the connecting rod is connected to the mounting plate 22, and the other end is fixed with a magnetic block 19. A limit ring rail 21 is fixed on the inner wall of the cylinder 15 at a position corresponding to the magnetic block 19. A magnetic block 20 is movably installed in the middle of the limit ring rail 21. The magnetic blocks 19 and 20 attract each other. A connecting column 17 is coaxially fixed in the middle of the fan 16. A lever 18 is fixed on the side wall of the connecting column 17. A movable plate 30 is movably installed on the side of the magnetic block 20 facing the middle of the cylinder 15 through a torsion spring. During continuous operation of the ventilation fan 6, the air drawn in is filtered by the dust filter 24, effectively intercepting dust and impurities in the air to ensure the cleanliness of the air entering the container. As air is supplied to the container, the fan 16 rotates, simultaneously driving the connecting column 17 and the lever 18. At this time, the lever 18 moves along the inclined direction of the movable plate 30 on the magnetic block, causing the movable plate 30 to rotate around its center of rotation and retract into the groove. The lever 18 can then smoothly pass through the movable plate 30 without driving the magnetic block 20 to move. The drive assembly will not drive the cleaning assembly, preventing continuous friction between the brush bristles 23 and the dust filter 24, which would cause wear on the dust filter 24 and extend its service life. After the lever 18 passes the area where the movable plate 30 is located, the movable plate 30 pops out again under the action of the torsion spring, returning to its initial position. Dust and impurities tend to accumulate on the outer wall of the dust filter 24 over time. Periodically, the drive motor of the ventilation fan 6 can be reversed, thereby driving the fan 16, connecting column 17, and lever 18 to rotate in the opposite direction. The lever 18 will move towards the side opposite to the tilt direction of the movable plate 30. After the lever 18 contacts the movable plate 30, it will push the movable plate 30 to move synchronously. The movable plate 30 drives the second magnetic block 20 to move within the limiting ring rail 21. Because the first magnetic block 19 and the second magnetic block 20 attract each other, the movement of the second magnetic block 20 will drive the first magnetic block 19 to move synchronously. The first magnetic block 19, in turn, drives the mounting plate 22 to rotate via the connecting rod. The brush on the mounting plate 22... The fan 23 rotates and cleans the outer wall of the dust filter 24, removing dust and other impurities adhering to the filter 24. This ensures that the filter 24 is always well-ventilated, thereby guaranteeing that the ventilation fan 6 can operate efficiently and stably, providing good ventilation conditions for the cooling and insulation of the container energy storage system. In addition, when the fan 16 rotates in the opposite direction, it can simultaneously exhaust air to the outside, further back-blowing the filter 24 and further cleaning the dust and other impurities adhering to it. This method of periodically rotating in the opposite direction to clean the filter 24 requires no additional manual operation, achieving automated cleaning and greatly reducing maintenance costs and manpower input.

[0029] The dust filter 24 is formed by the combination of the mounting ring 40 and the middle filter. Multiple limiting posts 32 are fixed on the side of the cylinder 15 away from the inner box 4. The mounting ring 40 of the dust filter 24 has mounting holes at positions corresponding to the limiting posts 32, and the limiting posts 32 are inserted into the mounting holes. By inserting the limiting post 32 into the mounting hole, the dust filter 24 can be securely installed on the cylinder 15. Not only is the installation process simple and quick, but during subsequent use, even if it is subjected to airflow impact or cleaning action of the cleaning component, the dust filter 24 can maintain a stable position and will not shift or fall off, ensuring the dust filtration effect and normal operation of the system. At the same time, it also facilitates quick and accurate disassembly and installation when the dust filter 24 needs to be replaced, improving maintenance efficiency.

[0030] The fixed rod 25 is fixed to the outer wall of the rotating ring 26, and the movable rod 29 is fixed to the side wall of the mounting plate 22. The end of the movable rod 29 away from the mounting plate 22 is slidably and elastically connected to the fixed rod 25. This connecting rod design, consisting of a fixed rod 25 and a movable rod 29, allows the mounting plate 22 to be pulled outwards. When deep cleaning or replacement of the dust filter 24 is required, the operator only needs to gently pull the mounting plate 22 outwards. Due to the sliding elastic connection between the movable rod 29 and the fixed rod 25, the mounting plate 22 will move outwards smoothly, causing the bristles 23 to move away from the dust filter 24 simultaneously, creating sufficient space for the removal of the dust filter 24. At this time, the operator can easily remove the dust filter 24 from the limiting post 32 at the end of the cylinder 15 for necessary cleaning or replacement. After cleaning or replacement, the mounting hole of the dust filter 24 is aligned with the limiting post 32 and inserted. Then, the mounting plate 22 is released. Under the action of the elastic connection, the mounting plate 22 will automatically reset, and the bristles 23 will re-contact the outer wall of the dust filter 24, restoring the cleaning function. This design not only improves the convenience of dust filter 24 maintenance but also ensures the precise fit between the cleaning components and the dust filter 24, guaranteeing the continuous and efficient operation of the system.

[0031] Limiting rods 33 are fixed at both ends of the mounting plate 22 on the side facing the dust filter 24. A ball bearing 34 is rotatably mounted at the end of the limiting rod 33, and the ball bearing 34 fits against the outer wall of the mounting ring 40 of the dust filter 24. After the dust filter 24 is installed in place, the mounting plate 22 will automatically reset under the action of the elastic connection. At this time, the limiting rod 33 and the ball bearing 34 can press firmly against the outer wall of the mounting ring 40 of the dust filter 24, so that the dust filter 24 remains stable during subsequent use and will not shift due to airflow impact or equipment vibration. This ensures the precise docking between the dust filter 24 and the cleaning component, thereby guaranteeing the continuity and stability of the dust filtration effect. Furthermore, the contact between the ball bearing 34 and the outer wall of the mounting ring 40 of the dust filter 24 greatly reduces the friction between the mounting plate 22 and the mounting ring 40 of the dust filter 24, making the rotation of the mounting plate 22 smoother, reducing energy loss caused by friction, reducing the workload of the drive component, and extending the service life of related components. In addition, the limiting rod 33 and the ball bearing 34 work together to support and limit the mounting plate 22, so that the bristles 23 and the dust filter 24 maintain an appropriate distance, ensuring the stability and reliability of the cleaning component's operation.

[0032] A drive rod 28 is slidably mounted on the movable rods 29 on both sides. The drive rod 28 is designed in an η shape. Both the short rod and the long rod of the drive rod 28 slide through the through holes opened on the movable rod 29. A return spring is installed between the drive rod 28 and the movable rod 29. The tension spring is used to pull the drive rod 28 as a whole to move towards the fixed sleeve 27. An arc-shaped block 31 is fixed on the side of the fixed sleeve 27 facing the mounting plate 22. The arc-shaped block 31 corresponds to the short rod of the drive rod 28. The long rod of the drive rod 28 slides through the through hole opened on the limiting rod 33, and a horizontal plate 35 is fixed at the end. Cleaning rods 36 are symmetrically fixed on the side wall of the horizontal plate 35. Horizontal bars 37 are fixed on the opposite side walls of the two cleaning rods 36. The cleaning rods 36 and the horizontal bars 37 are movably inserted into the bristles 23. When the ventilation fan 6 drives the fan 16 to rotate in the opposite direction to clean the dust filter 24, the drive rod 28 will move accordingly. Since the drive rod 28 is designed in an η shape and both its short and long rods slide through the through holes on the movable rod 29, during the movement of the drive rod 28, its short rod will contact and be squeezed against the top of the arc-shaped block 31 on the fixed sleeve 27, causing the drive rod 28 to move upward as a whole, thereby driving the long rod and the horizontal plate 35 fixed at the end of the long rod to move. The cleaning rod 36 and the horizontal bar 37 on the horizontal plate 35 will move inside the bristles 23. As the drive rod 28 continues to move, the horizontal bar 37 will push the bristles 23 to make the bristles 23 vibrate, shaking off the dust and other impurities attached to the bristles 23, enhancing the cleaning effect on the bristles 23 themselves, and ensuring that the bristles 23 can play a better role in the subsequent cleaning of the dust filter 24. After the short rod of the drive rod 28 has completely passed the surface of the arc-shaped block 31, the drive rod 28, the horizontal plate 35, the cleaning rod 36, and the horizontal bar 37 will automatically reset under the action of the return spring (that is, the short rod of the drive rod 28 moves one-third of the radius of the arc-shaped block 31 towards the cylinder 15). The short rod of the continuously rotating drive rod 28 moves up and down using the arc surface of the arc-shaped block 31, thereby repeatedly moving and cleaning the bristles 23 to achieve a better cleaning effect.

[0033] Example 2: Figure 4 and Figure 11 As shown in the first embodiment, another embodiment of the present invention is as follows: a collection trough 14 for collecting impurities is provided below the air exchange box 5, and a locking block 39 is symmetrically fixed at both ends of the collection trough 14. A locking groove 38 is symmetrically fixed at both ends of the bottom of the air exchange box 5, and the locking block 39 is slidably inserted into the locking groove 38. The collection trough 14 is securely installed below the ventilation box 5 through the cooperation of the locking block 39 and the locking slot 38, which facilitates the collection of impurities and subsequent cleaning and maintenance. The top of the collection trough 14 is designed to be open, so that it can directly receive falling dust and other impurities. The bottom of the collection trough 14 is set to be inclined. When dust and other impurities fall into the collection trough 14, they will slide along the inclined surface to the rear and eventually gather at the rear end of the collection trough 14. This can prevent impurities from accumulating too much in the collection trough 14 and affecting the collection effect. It also makes it easier to pour out the impurities more thoroughly when cleaning the collection trough 14.

[0034] like Figure 12 As shown, a control method for a cooling and insulation system of a containerized energy storage system includes the following steps: S1. After the system starts, the control unit first performs a self-test to confirm that all components are in normal condition. Then, it continuously monitors the ambient temperature inside and outside the inner box 4 through sensors. S2. The control unit compares the real-time monitoring data with the preset temperature threshold and automatically determines the working mode: if the internal temperature is higher than the upper threshold, it enters the heat dissipation mode; if the internal temperature is lower than the lower threshold, it enters the heat preservation mode. When the S3 cooling mode is activated, the rain shields on both sides of the outer casing 1 are open, and the ventilation fans 6 on both sides of the inner casing 4 start up quickly. The right ventilation fan 6 draws in the cold air from outside, filters it, and then sends it evenly from the bottom of the battery pack through the air duct 8. At the same time, the left ventilation fan 6 exhausts the hot air inside the casing 4, forming a smooth cooling cycle. S4. When the heat preservation mode is activated, the right rain shield opens, the left rain shield and the left ventilation fan 6 close. The heating element 13 and the ventilation fan 6 work together.
