Abstract
Description
Technical Field
[0001] This invention relates to the field of photovoltaic power generation technology, and in particular to a control and regulation device for distributed photovoltaic power generation. Background Technology
[0002] Photovoltaic (PV) power integration refers to the process of incorporating the electricity generated by photovoltaic (PV) power generation systems into the power system and achieving its rational utilization. Connecting the electricity generated by PV power generation equipment to the power grid completes the effective utilization of PV power. However, in practical applications, the power load in the power grid fluctuates, such as lower electricity load at night than during the day. If PV power is connected to the grid indiscriminately, there will be a situation of supply exceeding demand, resulting in energy waste. Therefore, it is necessary to rationally allocate PV power, that is, to rationally control and regulate PV power integration. For example, during the daytime when electricity demand is high, PV power generation is controlled to supplement demand, while at night when electricity demand is low, the supplementary function of PV power generation is stopped, and the generated electricity is stored for use during peak hours. This rational integration of PV power generation can reduce energy waste and is more energy-efficient and environmentally friendly.
[0003] A search of patent publication number "CN113128790B" reveals a method, apparatus, and terminal equipment for optimizing the absorption capacity of a distributed photovoltaic (PV) system. The method includes: acquiring a power generation prediction function, a load prediction function for non-charging loads, and charging load prediction data for rechargeable loads within a preset first time period; generating multiple charging schemes for the distributed PV system within the first time period based on the power generation prediction function, load prediction function, and charging load prediction data; calculating the purchase amount corresponding to each charging scheme, and selecting the charging scheme with the minimum purchase amount as the target charging scheme; and charging each charging load according to the target charging scheme within the first time period. The method provided by this invention can determine the optimal target charging scheme based on the power generation, load, and charging load conditions of the distributed PV system within the first time period, thereby reducing the purchase amount and improving the PV absorption capacity of the system.
[0004] Currently, most photovoltaic (PV) power grid integration control and regulation systems are centrally installed in power cabinets. During operation, processes such as the charging and discharging of energy storage batteries and the resistance heat generated by connecting wires produce significant heat inside the cabinet. Traditional fixed-type heat dissipation methods are insufficient for comprehensive cooling, resulting in consistently high temperatures within the cabinet and increasing the risk of damage to internal electrical components. Therefore, a distributed PV power grid integration control and regulation device is proposed. Summary of the Invention

A dust filter is fixedly connected to the air inlet slot. The air inlet slot and the inner cavity of the air intake box are linked by an air inlet pipe. A sealing ring is rotatably connected to the bottom of the driven ring. The sealing ring is fixedly connected to the inner wall of the cabinet and communicates with the inner cavity of the driven ring. The air intake box communicates with the inner cavity of the sealing ring.
[0010] Furthermore, a cleaning groove is provided inside the air inlet slot. Guide slide rods are fixedly connected to both sides of the inner cavity of the cleaning groove. Cleaning brushes are slidably connected to the guide slide rods on both sides.

The first magnetic plate is magnetically attracted to the air pressure plate. A pull rope is fixedly connected to the side wall of the air pressure plate. The other end of the pull rope extends through the cleaning groove and is fixedly connected to the bottom of the cleaning brush.
[0011] To improve heat dissipation, preferably, the heat dissipation part includes a heat dissipation plate, which is fixedly connected to the inner wall of the driven ring and communicates with the inner cavity of the driven ring. Multiple sets of heat dissipation holes are equally spaced on the side wall of the heat dissipation plate, and the output ends of the heat dissipation holes radiate outwards toward the side wall of the control and adjustment module.
[0012] Furthermore, the card holder is hollow inside, and multiple sets of air guide holes are equally spaced on the side wall of the card holder. Multiple sets of heat dissipation pipes are fixedly connected at equal intervals at the bottom grid of the card holder.

[0014] Compared with the prior art, the present invention provides a control and regulation device for distributed photovoltaic power generation, which has the following beneficial effects:
[0015] 1. This distributed photovoltaic power generation control and regulation device draws fresh air from outside into the cabinet through the rotation of the exhaust fan blades. The air is then blown along the heat dissipation holes toward the side wall of the control and regulation module. In conjunction with the meshing relationship between the driven gear and the drive gear, the driven ring drives the heat dissipation plate to rotate, allowing fresh air to be blown toward the control and regulation module from all directions. This achieves comprehensive cooling of the control and regulation module by blowing air. Furthermore, the rotational force generated during air extraction is used to achieve the rotational blowing of the cooling airflow, improving the cooling effect, saving the energy required for cooling, and improving energy saving.
[0016] 2. The control and regulation device for distributed photovoltaic power consumption guides the airflow inside the heat sink into the inner cavity of the card holder, so that the airflow is discharged along the air guide hole and the air blowing hole. This generates multiple sets of directional blowing heat dissipation airflow in the area around the energy storage battery, effectively removing the heat generated during the charging and discharging of the energy storage battery, improving the utilization effect of the heat dissipation airflow, reducing the energy consumption required for heat dissipation, achieving good energy saving, and thus effectively protecting the energy storage battery and improving its durability.
[0017] 3. The control and regulation device for distributed photovoltaic power generation utilizes the attraction between the first magnetic plate and the air pressure plate, along with the pull rope and cleaning brush, to draw airflow into the cabinet while simultaneously moving the cleaning brush along the dust-blocking surface of the dust filter, thereby cleaning the dust-blocking surface of the dust filter, ensuring the effectiveness of the dust filter, improving the flow speed of the heat dissipation airflow, and achieving effective heat dissipation.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0032] Example:
[0033] Reference Figures 1-10 A control and adjustment device for distributed photovoltaic power generation includes a cabinet 1. A mounting base 2 is fixedly connected to the bottom of the inner cavity of the cabinet 1. An energy storage battery 21 is inserted into the mounting base 2. A control and adjustment module 22 is fixedly connected to the top of the mounting base 2. The device also includes a driven ring 3 that rotates along the center of the inner cavity of the cabinet 1. A bearing ring 31 is fixedly connected to the inner wall of the driven ring 3. The inner wall of the bearing ring 31 is fixedly connected to the top of the inner cavity of the cabinet 1. A power unit that drives the driven ring 3 to rotate is fixedly connected to the top of the inner cavity of the cabinet 1. The power unit is provided with an air intake part for introducing external airflow into the interior of the cabinet 1. The driven ring 3 is provided with a heat dissipation part that evenly distributes the introduced airflow to various parts of the inner cavity of the cabinet 1.
[0034] Reference Figures 1-4 , Figures 6-10The power unit includes a drive motor 4, which is fixedly connected to the top of the cabinet 1. The output shaft of the drive motor 4 extends through the cabinet 1, and a drive gear 41 is fixedly connected to the bottom end of the output shaft. A driven gear 32 is fixedly connected to the driven ring 3, and the driven gear 32 meshes with the drive gear 41. The air intake unit includes an air intake box 5, which is fixed to the inner wall of the cabinet 1. The output shaft of the drive motor 4 passes through the center of the air intake box 5. An air intake blade 51 is fixedly connected to the outer wall of the output shaft of the drive motor 4 located inside the air intake box 5. An air inlet slot 52 is provided on the side wall of the cabinet 1. A dust filter 521 is fixedly connected. The air inlet slot 52 and the inner cavity of the air duct box 5 are linked by an air inlet pipe 53. A sealing ring 33 is rotatably connected to the bottom of the driven ring 3. The sealing ring 33 is fixedly connected to the inner wall of the cabinet 1 and communicates with the inner cavity of the driven ring 3. The air duct box 5 communicates with the inner cavity of the sealing ring 33. The heat dissipation part includes a heat dissipation plate 6. The heat dissipation plate 6 is fixedly connected to the inner wall of the driven ring 3 and communicates with the inner cavity of the driven ring 3. Multiple sets of heat dissipation holes 61 are opened at equal intervals on the side wall of the heat dissipation plate 6. There are five sets of heat dissipation holes 61, and each set contains six holes. The output end of the heat dissipation holes 61 radiates and extends to the side wall of the control and adjustment module 22.
[0035] With the above-described structure, the drive motor 4 is turned on, causing the air-driving blades 51 inside the air-driving box 5 to rotate. This draws fresh air from the outside into the air-driving box 5 through the air inlet slot 52, and through the inner cavity of the sealing ring 33 and the driven ring 3, it reaches the interior of the heat sink 6. Finally, it is blown towards the side wall of the control and adjustment module 22 through the heat dissipation holes 61. Furthermore, by utilizing the meshing relationship between the driven gear 32 and the drive gear 41, the driven ring 3 will drive the heat sink 6 to rotate along the center of the control and adjustment module 22, allowing fresh air to be blown towards the control and adjustment module 22 from all directions. This achieves comprehensive cooling of the control and adjustment module 22 by blowing air. At the same time as the air is being drawn in, the rotation of the cooling airflow is also achieved, which improves the cooling effect, saves the energy required for cooling, and improves the energy-saving effect.
[0036] Reference Figures 2-4The air inlet slot 52 is provided with a cleaning slot 54. Guide slide rods 541 are fixedly connected to both sides of the inner cavity of the cleaning slot 54. Cleaning brushes 542 are slidably connected to the guide slide rods 541 on both sides. The brush part of the cleaning brush 542 is in contact with the side wall of the dust filter 521. The bottom of the cleaning brush 542 and the bottom of the cleaning slot 54 are magnetically repelled. The cabinet 1 is provided with a pressure slot 55. A pressure plate 551 is slidably connected to the pressure slot 55. A first spring 552 is fixedly connected between the side wall of the pressure plate 551 and the pressure slot 55. A first magnetic plate 553 is fixedly connected to the end of the air duct blade 51. The first magnetic plate 553 and the pressure plate 551 are magnetically attracted. A pull rope 554 is fixedly connected to the side wall of the pressure plate 551. The other end of the pull rope 554 extends through the cleaning slot 54 and is fixedly connected to the bottom of the cleaning brush 542.
[0037] Through the above-described structure, the dust filter 521 effectively isolates dust in the fresh airflow, preventing dust from entering the cabinet 1 and causing intrusion into its internal components, thus improving the protection effect. When the exhaust fan blades 51 rotate, the attraction between the first magnetic plate 553 and the air pressure plate 551 pulls the air pressure plate 551 towards the side closer to the first magnetic plate 553, thereby pulling the pull rope 554 and causing the cleaning brush 542 to slide down along the guide rod 541, thereby cleaning the dust-blocking surface of the dust filter 521. When the two separate from the magnetic area, the repulsive action between the cleaning brush 542 and the air inlet groove 52 will reset it. This process is repeated to ensure the effectiveness of the dust filter 521, improve the flow speed of the heat dissipation airflow, and achieve effective heat dissipation.
[0038] Reference Figures 5-10The card holder 2 is hollow inside, and multiple sets of air guide holes 25 are evenly spaced on the side wall of the card holder 2. There are five sets of air guide holes 25, and each set contains seven air guide holes. Multiple sets of heat dissipation pipes 23 are fixedly connected at equal intervals at the bottom grille of the card holder 2. There are four sets of heat dissipation pipes 23, and each set contains three heat dissipation pipes. Multiple sets of air blowing holes 231 are evenly spaced on the side wall of the heat dissipation pipes 23. Preferably, there are ten sets of air blowing holes 231 on each heat dissipation pipe 23, and each set contains three air blowing holes. The heat dissipation pipes 23 are connected to the inner cavity of the card holder 2. Air guide blocks 24 are fixedly connected to both sides of the top of the card holder 2. The air guide block 24 is connected to the inner cavity of the card seat 2. The inner wall of the heat sink 6 is slidably connected to the sealing plate 62. The two sides of the heat sink 6 are fixedly connected to the positioning slide rod 621. The sealing plate 62 is slidably sleeved on the positioning slide rod 621 through the connecting ear 622. The outer wall of the positioning slide rod 621 above the connecting ear 622 is sleeved with a second spring 623. The side wall of the sealing plate 62 is provided with a connecting hole 624. The connecting hole 624 is adapted to the heat sink hole 61. The bottom of the heat sink 6 is provided with an air guide hole 63. The bottom of the heat sink 6 and the top of the air guide block 24 slide together. The bottom of the sealing plate 62 and the top of the air guide block 24 are magnetically repelled.
[0039] With the above structure, when the bottom of the heat sink 6 reaches above the air guide block 24, the repulsive force between the sealing plate 62 and the air guide block 24 will cause the sealing plate 62 to rise upward, causing the connecting hole 624 and the heat dissipation hole 61 to be misaligned, thus sealing the heat dissipation hole 61. At this time, the airflow entering the inner cavity of the heat sink 6 will pass downward through the air guide hole 63 and through the air guide block 24 into the inner cavity of the snap-fit seat 2. At this time, part of the airflow will be blown along the air guide hole 25 on the side wall of the snap-fit seat 2 towards the side wall of the energy storage battery 21, and another part of the airflow will be blown out from the bottom of the energy storage battery 21 along the air blowing hole 231 on the side wall of the heat dissipation pipe 23. This generates multiple sets of directional blowing heat dissipation airflows in the area around the energy storage battery 21, effectively carrying away the heat generated when the energy storage battery 21 is charging and discharging, improving the utilization effect of the heat dissipation airflow, reducing the energy consumption required for heat dissipation, achieving good energy saving, and thus effectively protecting the energy storage battery 21 and improving the durability of the energy storage battery 21.
[0040] Reference Figure 1 , Figure 2 and Figure 5 The cabinet 1 has an air outlet slot 7 on its side wall. A dust baffle 71 is rotatably connected inside the air outlet slot 7. The bottom of the air outlet slot 7 is inclined, and the bottom of the dust baffle 71 is parallel to the bottom of the air outlet slot 7. As fresh air continuously enters the cabinet 1, the internal pressure will increase, thereby opening the dust baffle 71 inside the air outlet slot 7. This allows only the airflow inside the cabinet 1 to be discharged, effectively preventing external airflow from carrying dust into the cabinet, achieving a good dust-blocking effect and improving the protection effect.
[0041] Reference Figure 1 , Figure 2 and Figure 11 The energy storage battery 21 is symmetrically arranged in two groups along the central partition of the card holder 2, and each group of energy storage batteries 21 is divided into two blocks. The two blocks of energy storage batteries 21 in the same group are electrically connected. One of the blocks of energy storage batteries 21 in each group is electrically connected to the internal electrical terminal of the control and regulation module 22. The external terminal of the control and regulation module 22 extends through to the top of the cabinet 1. The external terminal is used to make electrical connections with the power grid and the photovoltaic power generation equipment. The control and regulation module 22 includes a power generation acquisition module, a power grid load acquisition module, and a charge and discharge conversion module. The power generation acquisition module, the power grid load acquisition module, and the charge and discharge conversion module are electrically connected. The power generation acquisition module is used to acquire the real-time power generation of the photovoltaic power generation equipment. The power grid load acquisition module is used to acquire the real-time load data in the power grid. The charge and discharge conversion module is used to compare the power generation data with the power grid load data and switch the energy storage battery 21 to the charging or discharging state according to the comparison result.
[0042] Reference Figures 1-11 In this invention, during use, the external terminals at the top of the control and regulation module 22 are electrically connected to the power grid and the photovoltaic power generation equipment, respectively. At this time, the power generation acquisition module obtains real-time power generation data of the photovoltaic power generation equipment, and the power grid load acquisition module obtains real-time load data of the power grid. Then, the charge and discharge conversion module compares the two sets of data. When the power grid load is lower than the power demand, the energy storage battery 21 will be converted to a discharge state to consume the electricity generated by the photovoltaic power generation, thereby increasing the power grid load to meet the power demand. When the power grid load is higher than or equal to the power demand, the energy storage battery 21 will be converted to a charging state to store and collect the electricity generated by the photovoltaic power generation equipment for supplementary use when the power is insufficient. This adaptively completes the photovoltaic consumption, improves the stability of the power grid, and achieves reasonable allocation of photovoltaic power, reduces power waste, and improves energy saving effect.
[0043] While photovoltaic power is being absorbed, the drive motor 4 is turned on, causing the air intake blades 51 inside the air intake box 5 to rotate. This draws fresh air from the outside into the air intake box 5 through the air inlet slot 52. Combined with the dust filter 521, this effectively isolates dust from the fresh airflow, preventing dust from entering the cabinet 1 and causing intrusion into internal components, thus improving protection. As the air intake blades 51 rotate, the attraction between the first magnetic plate 553 and the air pressure plate 551 pulls the air pressure plate 551 closer to the first magnetic plate 553. This pulls the pull rope 554, causing the cleaning brush 542 to slide downwards along the guide rod 541, cleaning the dust-blocking surface of the dust filter 521. Once the two are separated from the magnetic area, the repulsive force between the cleaning brush 542 and the air inlet slot 52... This will reset the filter screen 521, and repeat this process to ensure the effectiveness of the filter screen 521, improve the flow speed of the cooling airflow, and achieve effective heat dissipation. Subsequently, under the thrust generated on the other side of the exhaust fan blade 51, the fresh airflow passes through the inner cavity of the sealing ring 33 and the driven ring 3, reaches the interior of the heat sink 6, and is finally blown towards the side wall of the control and adjustment module 22 through the heat dissipation hole 61. Furthermore, by utilizing the meshing relationship between the driven gear 32 and the drive gear 41, the driven ring 3 will drive the heat sink 6 to rotate along the center of the control and adjustment module 22, so that the fresh airflow blows towards the control and adjustment module 22 from all directions, thereby achieving comprehensive cooling of the control and adjustment module 22. At the same time as the air is being drawn in, the rotation of the cooling airflow is also achieved, which improves the cooling effect, saves the energy required for cooling, and improves the energy-saving effect.
[0044] Furthermore, when the bottom of the heat sink 6 reaches above the air guide block 24, the repulsive force between the sealing plate 62 and the air guide block 24 will cause the sealing plate 62 to rise upwards, causing the connecting hole 624 to be misaligned with the heat dissipation hole 61, thus sealing the heat dissipation hole 61. At this time, the airflow entering the inner cavity of the heat sink 6 will pass downwards through the air guide hole 63 and through the air guide block 24 into the inner cavity of the mounting bracket 2. At this time, part of the airflow will be blown along the air guide hole 25 on the side wall of the mounting bracket 2 towards the side wall of the energy storage battery 21, and another part of the airflow will be blown along the air blowing hole 231 on the side wall of the heat pipe 23 from the bottom of the energy storage battery 21. The airflow is blown out, thereby generating multiple sets of directional cooling airflows around the energy storage battery 21. This effectively removes the heat generated during the charging and discharging of the energy storage battery 21, improving the utilization of the cooling airflow, reducing the energy consumption required for cooling, and achieving good energy-saving effect. This also effectively protects the energy storage battery 21 and improves its durability. Finally, as fresh airflow continuously enters the cabinet 1, its pressure will increase, thereby opening the dust baffle 71 in the air outlet slot 7, allowing only the airflow inside the cabinet 1 to be discharged, effectively preventing external airflow from carrying dust into the cabinet, achieving a good dust-blocking effect and improving the protection effect.
