Description

Technical Field

[0001] This invention relates to the field of charging cabinet technology, and in particular to a modular box-type energy storage charging cabinet and its operation management method. Background Technology

[0002] Modular box-type energy storage charging cabinets are energy storage systems that integrate energy storage units, power conversion equipment, battery management systems (BMS), energy management systems (EMS, if equipped), and other necessary components. These components are cleverly assembled in a standardized enclosure. Modular box-type energy storage charging cabinets adopt a modular design concept, which allows each component to be replaced or upgraded independently, facilitating maintenance and expansion. Equipped with an advanced battery management system (BMS), they can monitor battery status in real time, optimize charging and discharging strategies, and extend battery life.

[0003] Existing box-type energy storage charging cabinets typically use a combination of ventilation windows, dust filters, and cooling fans for ventilation and heat dissipation. The dust filters are installed on the inner walls of each ventilation window to prevent dust and other impurities from entering the energy storage charging cabinet. However, during long-term use, a certain amount of dust and impurities will adhere to the side of the dust filter that is closest to the outside air, which usually requires regular manual cleaning and consumes manual labor. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art:

[0005] During long-term use, the dust filter of existing box-type energy storage charging cabinets will accumulate a certain amount of dust and impurities on the side facing the outside air, which usually requires regular manual cleaning, consuming human labor.

[0006] A modular box-type energy storage and charging cabinet and its operation management method are proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solutions:

[0008] A modular box-type energy storage charging cabinet includes a charging cabinet body. Air inlet slots and exhaust slots are respectively provided on both sides of the charging cabinet body. Dust filters are fixed to the inner walls of both air inlet slots and exhaust slots. Cleaning components for use with the corresponding dust filters are provided on both sides of the charging cabinet body. Each cleaning component includes a left mounting base and a right mounting base. Multiple rotating plates are rotatably arranged between the left and right mounting bases. A brush layer is fixed to one end of each rotating plate. A linkage unit for rotating the corresponding rotating plate is provided in the right mounting base, and a drive unit for rotating the corresponding rotating plate is provided in the left mounting base.

[0009] As a further technical solution of the present invention, each of the linkage units includes a right cavity opened in the right mounting seat, and a right rotating shaft is fixed at one end of each rotating plate near the right mounting seat. The right rotating shaft rotates through the right cavity, and a belt drive group is provided between two adjacent right rotating shafts.

[0010] As a further technical solution of the present invention, each of the driving units includes a left cavity opened in the left mounting seat, and a left rotating shaft is fixed on the side of each rotating plate near the left mounting seat. The left rotating shaft rotates through the left cavity and a stepper motor is fixed in the left cavity. The drive shaft of the stepper motor is fixedly connected to one of the left rotating shafts.

[0011] As a further technical solution of the present invention, two pairs of T-shaped lifting slots are provided on both sides of the charging cabinet body, and a T-shaped lifting slider is fixed in each T-shaped lifting slot. The right mounting seat and the left mounting seat are fixed with connecting blocks between them and the adjacent T-shaped lifting sliders. Both sides of the charging cabinet body are provided with lifting units that cooperate with the lifting of the right mounting seat and the left mounting seat.

[0012] As a further technical solution of the present invention, each of the lifting units includes two electric push rods, each electric push rod is fixed on the side wall of the charging cabinet body, and the end of the telescopic end of each electric push rod is fixedly connected to the lower end face of the adjacent connecting block.

[0013] As a further technical solution of the present invention, both sides of the charging cabinet body are fixed with U-shaped rain covers for use with dust filters, and the open end of the U-shaped rain covers faces downward.

[0014] As a further technical solution of the present invention, each of the rotating plates has a built-in groove on the side away from the brush layer, and a telescopic plate is movably arranged in each built-in groove. An adsorption component is arranged between the built-in groove and the telescopic plate.

[0015] As a further technical solution of the present invention, each of the adsorption components includes an electromagnet fixed to the top of the built-in groove, a metal plate for use with the electromagnet is fixed on the upper end surface of the telescopic plate, and multiple guide and limiting units are provided between the metal plate and the built-in groove.

[0016] As a further technical solution of the present invention, multiple limiting sliders are fixed on both sides of each metal plate, and multiple limiting grooves are opened on both sides of the inner wall of the built-in groove to cooperate with the limiting sliders.

[0017] A method for managing the operation of a modular box-type energy storage charging cabinet, the specific steps of which are as follows:

[0018] Step 1: In the initial state, the rotating plate is perpendicular to the dust filter. When it is necessary to clean the outer surface of the dust filter, the driving unit and the linkage unit work together to drive each rotating plate to rotate with the brush layer. As the brush layer rotates, it will wipe and clean the outer surface of the dust filter.

[0019] Step 2: After the rotating plate drives the brush layer to rotate at this height for a period of time, under the action of the lifting unit, the two cooperating right and left mounting seats are driven to move upward a distance, thereby driving each rotating plate and brush layer to move upward a distance, thereby changing the cleaning position of the brush layer on the dust filter and cleaning the areas that were not cleaned before.

[0020] Step 3: After the entire cleaning operation is completed, the lifting unit drives the two cooperating right and left mounting seats to move down to the initial height position. With the cooperation of the drive unit and the linkage unit, the rotating plate is made to rotate again to a state perpendicular to the dust filter.

[0021] The beneficial effects of this invention are:

[0022] 1. In the initial state, the rotating plates are perpendicular to the dust filter to avoid affecting the ventilation effect of the air intake and exhaust channels. During long-term use, the surface of the dust filter closest to the outside air will accumulate a certain amount of dust. At this time, with the cooperation of the drive unit and the linkage unit, each rotating plate is driven to rotate with the brush layer. As the brush layer rotates, it wipes and cleans the outer surface of the dust filter, thereby sweeping away the dust and impurities adhering to the outer surface of the dust filter. It is easy to use. After the cleaning operation is completed, with the cooperation of the drive unit and the linkage unit, the rotating plates are made to rotate back to the state perpendicular to the dust filter.

[0023] 2. After the rotating plate drives the brush layer to rotate at this height for a period of time, under the action of the lifting unit, it can drive the two cooperating right and left mounting seats to move upward a certain distance, thereby driving each rotating plate and brush layer to move upward a certain distance, thus changing the cleaning position of the brush layer on the dust filter, cleaning the areas that were not cleaned before, and achieving a good cleaning effect.

[0024] 3. In the initial state, the telescopic plate is inside the built-in groove. When it rains, under the action of the drive unit and the linkage unit, each rotating plate is driven to rotate to an inclined state. At this time, the adsorption component releases the adsorption and fixation of the telescopic plate. Under the action of gravity, the telescopic plate slides along the built-in groove, thereby extending a portion of the area at the end of the rotating plate, thereby increasing the rain-proof effect and preventing rainwater from being splashed onto the surface of the dust filter by the wind.

[0036] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0037] Reference Figures 1-10A modular box-type energy storage charging cabinet includes a charging cabinet body 1. The charging cabinet body 1 adopts a modular design. The charging cabinet body 1 is the prior art. Air inlet slots 2 and exhaust slots 3 are respectively opened on both sides of the charging cabinet body 1. Multiple ventilation fan blade groups are arranged on the inner wall of the charging cabinet body 1. The ventilation fan blade groups are the prior art and are used to accelerate the air flow speed inside the charging cabinet body 1, thereby accelerating the ventilation and heat dissipation effect inside the charging cabinet body 1.

[0038] Dust filters 4 are fixed on the inner walls of the air intake channel 2 and the exhaust channel 3. Cleaning components are provided on both sides of the charging cabinet body 1 to cooperate with the corresponding dust filters 4. Each cleaning component includes a left mounting base 5 and a right mounting base 6. Multiple rotating plates 7 are rotatably arranged between the left mounting base 5 and the right mounting base 6. A brush layer 8 is fixed at one end of each rotating plate 7. A linkage unit is provided in the right mounting base 6 to cooperate with the rotation of the corresponding rotating plate 7. A drive unit is provided in the left mounting base 5 to cooperate with the rotation of the corresponding rotating plate 7.

[0039] In the initial state, the rotating plate 7 is perpendicular to the dust filter 4 to avoid affecting the ventilation effect of the air intake channel 2 and the exhaust channel 3. During long-term use, a certain amount of dust will adhere to the surface of the dust filter 4 on the side closest to the outside air. At this time, with the cooperation of the drive unit and the linkage unit, each rotating plate 7 is driven to rotate with the brush layer 8. As the brush layer 8 rotates, it wipes and cleans the outer surface of the dust filter 4, thereby sweeping away the dust and impurities adhering to the outer surface of the dust filter 4. It is convenient to use and does not require manual cleaning. After the cleaning operation is completed, with the cooperation of the drive unit and the linkage unit, the rotating plate 7 is made to rotate again to the state perpendicular to the dust filter 4.

[0040] While the rotating plate 7 and the brush layer 8 are cleaning the outer surface of the dust filter 4, the ventilation fan blade assembly can be paused as needed.

[0041] Each linkage unit includes a right cavity 9 opened in the right mounting base 6. Each rotating plate 7 has a right rotating shaft 10 fixed at one end near the right mounting base 6. The right rotating shaft 10 rotates through the right cavity 9. A belt drive group 11 is provided between two adjacent right rotating shafts 10.

[0042] With the belt drive assembly 11 in place, when one of the right-side rotating shafts 10 rotates, it will drive the other right-side rotating shafts 10 to rotate, thereby driving the corresponding rotating plates 7 to rotate.

[0043] Each drive unit includes a left cavity 12 opened in the left mounting base 5. Each rotating plate 7 has a left rotating shaft 13 fixed on the side near the left mounting base 5. The left rotating shaft 13 rotates through into the left cavity 12. A stepper motor 14 is fixed in the left cavity 12. The drive shaft of the stepper motor 14 is fixedly connected to one of the left rotating shafts 13.

[0044] A brake device can be added to the tail of the stepper motor 14 to achieve self-locking of the stepper motor 14 when power is cut off. This technology is existing technology.

[0045] When the stepper motor 14 is powered on, it will drive the corresponding left rotating shaft 13 to rotate, thereby driving the corresponding rotating plate 7 and right rotating shaft 10 to rotate. Under the action of each belt drive group 11, it will drive the other right rotating shaft 10 and rotating plate 7 to rotate.

[0046] The charging cabinet body 1 has two pairs of T-shaped lifting slots 15 on both sides. Each T-shaped lifting slot 15 has a fixed T-shaped lifting slider 16. The right mounting seat 6 and the left mounting seat 5 are fixed with a connecting block 17 between them and the adjacent T-shaped lifting slider 16. The charging cabinet body 1 has lifting units on both sides that work together with the right mounting seat 6 and the left mounting seat 5 to lift.

[0047] After the rotating plate 7 drives the brush layer 8 to rotate at this height for a period of time, under the action of the lifting unit, it can drive the two cooperating right mounting bases 6 and left mounting bases 5 to move upward a certain distance, thereby driving each rotating plate 7 and brush layer 8 to move upward a certain distance, thereby changing the cleaning position of the brush layer 8 on the dust filter 4, cleaning the areas that were not cleaned before, and achieving a good cleaning effect.

[0048] After the entire cleaning operation is completed, the lifting unit drives the two cooperating right-side mounting base 6 and left-side mounting base 5 to move downwards to the initial height position.

[0049] The T-shaped lifting groove 15, T-shaped lifting slider 16 and connecting block 17 work together to limit and guide the lifting movement of the right mounting seat 6 and the left mounting seat 5. In the initial state, the lower end face of the T-shaped lifting slider 16 contacts the inner bottom of the T-shaped lifting groove 15, thereby supporting the weight of the connecting block 17, the right mounting seat 6, the left mounting seat 5 and each rotating plate 7.

[0050] Each lifting unit includes two electric push rods 18, each electric push rod 18 is fixed to the side wall of the charging cabinet body 1, and the end of the telescopic end of each electric push rod 18 is fixedly connected to the lower end face of the adjacent connecting block 17.

[0051] In the initial state, the telescopic end of the electric actuator 18 is in a retracted state. When it is necessary to raise the vertical height of the rotating plate 7, the telescopic end of the electric actuator 18 extends, thereby pushing the corresponding connecting block 17, right mounting seat 6, left mounting seat 5 and rotating plate 7 to move upward.

[0052] As needed, a dustproof telescopic sleeve can be fitted onto the outer surface of the telescopic end of the electric actuator 18.

[0053] Both sides of the charging cabinet body 1 are fixed with U-shaped rain covers 19 for use with dust filters 4, with the open end of the U-shaped rain covers 19 facing downwards.

[0054] Because the intake channel 2 and exhaust channel 3 have large opening areas, the U-shaped rain shield 19 prevents rainwater from flowing directly onto the surface of the dust filter 4 on rainy days.

[0055] Each rotating plate 7 has an internal groove 20 on the side away from the brush layer 8. A telescopic plate 21 is movably installed in each internal groove 20. An adsorption component is provided between the internal groove 20 and the telescopic plate 21.

[0056] In the initial state, the telescopic plate 21 is inside the built-in groove 20. When it rains, under the action of the drive unit and the linkage unit, each rotating plate 7 is driven to rotate to an inclined state. At this time, the adsorption component releases the adsorption and fixation of the telescopic plate 21. Under the action of gravity, the telescopic plate 21 slides along the built-in groove 20, thereby extending a portion of the area at the end of the rotating plate 7, thereby increasing the rainproof effect and preventing rainwater from being splashed onto the surface of the dust filter 4 by the wind.

[0057] When it is necessary to retract the telescopic plate 21 into the built-in groove 20, the rotating plate 7 can be rotated to a vertical position (the brush layer 8 is located below the rotating plate 7, and the telescopic plate 21 is located above the rotating plate 7). At this time, the telescopic plate 21 falls into the built-in groove 20 under the action of gravity, and then the adsorption component adsorbs and fixes the telescopic plate 21.

[0058] Each adsorption assembly includes an electromagnet 22 fixed to the top of the built-in groove 20, and a metal plate 23 for use with the electromagnet 22 is fixed to the upper end face of the telescopic plate 21. Multiple guide and limiting units are provided between the metal plate 23 and the built-in groove 20.

[0059] When the rotating plate 7 drives the brush layer 8 to rotate and clean the surface of the dust filter 4, the electromagnet 22 is energized and works to attract the metal plate 23, thereby limiting and fixing the telescopic plate 21 in the built-in groove 20.

[0060] In the initial state, when the rotating plate 7 is perpendicular to the dust filter 4, the electromagnet 22 can be de-energized, and the telescopic plate 21 will not move along the built-in groove 20.

[0061] A cavity three can be opened inside the rotating plate 7, and a storage battery is installed inside the cavity three. Solar photovoltaic panels are installed on both sides of the rotating plate 7. The solar photovoltaic panels are used to charge the storage battery, and the storage battery is used to supply power to the electromagnet 22.

[0062] Multiple limiting sliders 24 are fixed on both sides of each metal plate 23, and multiple limiting grooves are opened on both sides of the inner wall of the built-in groove 20 to cooperate with the limiting sliders 24.

[0063] By using the limit slider 24 in conjunction with the limit groove, the telescopic plate 21 is prevented from falling out of the built-in groove 20 when it moves within the built-in groove 20.

[0064] A method for managing the operation of a modular box-type energy storage charging cabinet, the specific steps of which are as follows:

[0065] Step 1: In the initial state, the rotating plate 7 is perpendicular to the dust filter 4. When it is necessary to clean the outer surface of the dust filter 4, the rotating plate 7 is driven to rotate with the brush layer 8 under the cooperation of the drive unit and the linkage unit. The brush layer 8 will wipe and clean the outer surface of the dust filter 4 as it rotates.

[0066] Step 2: After the rotating plate 7 drives the brush layer 8 to rotate at this position for a period of time, under the action of the lifting unit, the two cooperating right mounting bases 6 and left mounting bases 5 are driven to move upward a certain distance, thereby driving each rotating plate 7 and brush layer 8 to move upward a certain distance, thereby changing the cleaning position of the brush layer 8 on the dust filter 4, and cleaning the areas that were not cleaned before.

[0067] Step 3: After the entire cleaning operation is completed, the lifting unit drives the two cooperating right mounting bases 6 and left mounting bases 5 to move down to the initial height position. With the cooperation of the drive unit and the linkage unit, the rotating plate 7 is made to rotate again to a state perpendicular to the dust filter 4.

[0068] In use, the rotating plate 7 is initially perpendicular to the dust filter 4 to avoid affecting the ventilation effect of the air inlet channel 2 and the exhaust channel 3. During long-term use, a certain amount of dust will adhere to the surface of the dust filter 4 on the side closest to the outside air. At this time, with the cooperation of the drive unit and the linkage unit, each rotating plate 7 is driven to rotate with the brush layer 8. As the brush layer 8 rotates, it wipes and cleans the outer surface of the dust filter 4, thereby sweeping away the dust and impurities adhering to the outer surface of the dust filter 4. It is convenient to use. After the cleaning operation is completed, with the cooperation of the drive unit and the linkage unit, the rotating plate 7 is made to rotate again to the state perpendicular to the dust filter 4.

[0069] After the rotating plate 7 drives the brush layer 8 to rotate at this position for a period of time, under the action of the lifting unit, it can drive the two cooperating right mounting bases 6 and left mounting bases 5 to move upward a certain distance, thereby driving each rotating plate 7 and brush layer 8 to move upward a certain distance, thereby changing the cleaning position of the brush layer 8 on the dust filter 4, cleaning the areas that were not cleaned before, and the cleaning effect is good.

[0070] In the initial state, the telescopic plate 21 is inside the built-in groove 20. When it rains, under the action of the drive unit and the linkage unit, each rotating plate 7 is driven to rotate to an inclined state. At this time, the adsorption component releases the adsorption and fixation of the telescopic plate 21. Under the action of gravity, the telescopic plate 21 slides along the built-in groove 20, thereby extending a portion of the area at the end of the rotating plate 7, thereby increasing the rainproof effect and preventing rainwater from being splashed onto the surface of the dust filter 4 by the wind.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
