Description

TECHNICAL FIELD

[0001] The application relates to the technical field of photovoltaic energy storage power stations, in particular to a new energy photovoltaic energy storage power station. BACKGROUND

[0002] In the development of new energy photovoltaic energy storage power stations, the insufficient heat dissipation performance of energy storage devices has become a core bottleneck restricting the safety and efficiency of the system. The energy storage equipment of the photovoltaic energy storage power station generates a large amount of heat during the charging and discharging process. If the heat cannot be dissipated in time and effectively, the battery pack temperature will be too high, accelerating the battery aging and causing the risk of thermal runaway. The traditional heat dissipation mode has significant defects: the heat dissipation efficiency is low and the temperature distribution is uneven. For example, in the summer in the northwest desert area, the temperature in the battery compartment can reach more than 60 DEG C, resulting in a 30%-50% increase in the battery capacity attenuation rate, and the forced convection of the air cooling system depends on the fan, which has the risk of failure due to dust blocking the heat dissipation channel.

[0003] With the increase of the capacity of the energy storage battery and the improvement of the integration, the heat generation density of the battery pack is significantly increased, and the cooling capacity of the air cooling system cannot cope. For example, in the high-power charging and discharging scene, the temperature difference of the battery can reach more than 10 DEG C, resulting in a decrease in the performance consistency of the battery, which seriously affects the overall life and stability of the energy storage system. At the same time, the outdoor photovoltaic energy storage power station often faces high temperature, high humidity, dust and other harsh environments, and the environmental adaptability of the traditional heat dissipation system is insufficient, which further aggravates the heat dissipation problem.

[0007] Cooling assembly for temperature protection in a container, the cooling assembly is fixedly installed on one side of the outer surface of the container. When the new energy photovoltaic power station is running, the solar radiation is converted into direct current by the photovoltaic panel, and then the direct current is converted into alternating current by the inverter installed in the air-cooled installation cabinet, which is suitable for the demand of power grid or electrical equipment. Due to the long-term solar radiation of the container and the energy storage support, a large amount of heat will be generated during the charging and discharging process of the energy storage equipment. If it cannot be cooled in time, it will cause the battery pack temperature to be too high. The traditional cooling method has obvious defects: low cooling efficiency and uneven temperature distribution. For example, in the summer in the northwest desert area, the temperature in the battery compartment can reach above ℃, which causes the battery capacity to decay at a rate of 30%-50% faster.

[0041] The cleaning assembly 4 comprises a bottom support sliding frame 42, one side of the outer surface of the bottom support sliding frame 42 is fixedly installed with a connecting plate 41, the outer surface of the connecting plate 41 is fixedly installed with an extension plate 43, and the bottom of the extension plate 43 is fixedly installed with a cleaning brush 44. The bottom support sliding frame 42 is installed below the first clamping rod 34, the second clamping rod 33 and the photovoltaic panel 35, and is installed in the guide groove 38 arranged at the bottom of the photovoltaic panel 35. When encountering strong wind, the air flow pushes the extension plate 43, so that the extension plate 43 drives the bottom support sliding frame 42 to slide between the lifting top plate 31 and the guide groove 38, and drives the cleaning brush 44 to clean the impurities falling on the surface of the photovoltaic panel 35, so as to avoid that the impurities cover the photovoltaic panel 35 after the strong wind and need to wait for the maintenance of the staff.

[0043] A cooling assembly 2 is arranged on one side of the outer surface of the container 1 for temperature reduction protection. During operation of the new energy photovoltaic power station, the solar radiation is converted into direct current by the photovoltaic panel, and then the direct current is converted into alternating current by the inverter installed in the air-cooled installation cabinet 6, which is suitable for the power grid or the power equipment demand. Due to the long-time solar radiation of the container 1 and the energy storage support 3, a large amount of heat will be generated during the charging and discharging process of the energy storage equipment. If the heat cannot be dissipated in time and effectively, the temperature of the battery pack will be too high, which will lead to the rapid attenuation of the battery capacity by 30%-50%. At the same time, the air-cooled system relies on the forced convection of the fan, which has the risk of failure due to dust blocking the heat dissipation channel. Therefore, in order to improve the heat dissipation effect in the container 1, cooling circulating pipes 8 are installed inside the container 1 to make the cooling liquid flow in the air-cooled installation cabinet 6. When the fan cools the battery pack, the cooling liquid flow cools the high-temperature air flow that cannot be dissipated, thereby improving the cooling efficiency in the container 1. When encountering strong wind weather, the air flow drives the cleaning assembly 4 to slide on the surface of the energy storage support 3 and clean the surface of the photovoltaic panel.

The staff connects the water pump with one side of the bent pipe 22, and injects the cooling liquid into the bent pipe 22, so that the cooling liquid flows in the container 1 along the cooling circulation pipe 8. Since the cooling circulation pipe 8 is installed between the two air-cooled cabinets 6, the high-temperature airflow in the cabinet is blown out by the rotation of the fan in the air-cooled cabinet 6, and then diffused to the cooling circulation pipe 8 with low temperature. The cooling circulation pipe 8 is made of easy heat-conducting material. When the high-temperature airflow contacts the cooling circulation pipe 8, the heat in the container 1 is conducted to the cooling liquid in the cooling circulation pipe 8, and then flows into the other side of the bent pipe 22 with the cooling liquid, so as to take out the heat in the container 1 which is not easy to dissipate.

[0045] The clamping frame 23 is fixedly installed on one side of the outer surface of the container 1, the bent pipe 22 is fixedly connected with the cooling circulation pipe 8, and the flow guide 28 is movably installed in the inner part of the cooling circulation pipe 8.

[0046] The second embodiment is based on the first embodiment, please refer to Figures 5 to 7 As shown in the figure, the flow guide 28 comprises a fixed ring 281, the inner part of the fixed ring 281 is fixedly provided with an inner support frame 282, the outer surface of the inner support frame 282 is fixedly provided with a spring band 285, the spring band 285 is provided with six, the outer surface of the six spring bands 285 is fixedly provided with a swing block 286, the outer surface of the swing block 286 is fixedly provided with a spring 283, and the outer surface of the swing block 286 and the spring 283 is sleeved with an inner support disc 284. Before the cooling liquid is injected into the bent pipe 22, the staff adjusts the position of the two conical plugs 27 by pushing the push pipe 25, so as to adjust the flow speed of the cooling liquid. The cooling liquid passes through the inner support frame 282 when being injected, the inner support disc 284 is slid to one side of the cooling circulation pipe 8 by the cooling liquid, the swing block 286 slides in the inner support disc 284 under the impact of the cooling liquid, the swing block 286 is extruded and shrunk to the spring 283, and the spring band 285 is deformed, so as to change the caliber of the cooling liquid flow. With the change of the caliber of the cooling circulation pipe 8, the cooling liquid in the cooling circulation pipe 8 flows intermittently, and the cooling liquid can fully absorb heat in the standby stage, so as to avoid the waste of the cooling liquid which is not completely heated and discharged continuously.

When the air flow pushes the extension plate 43 to displace, the inclined plate 424 slides on the surface of the lifting top plate 31 and drives the tripods 423 and the sliding blocks 421 to slide in the guide groove 38, the tripods 423 are supported below the photovoltaic panel 35, and a plurality of tripods 423 are provided in a hollow shape, which reinforces and supports the inclined photovoltaic panel 35 to disperse the wind pressure, improves the ventilation of the bottom of the photovoltaic panel 35 during installation, and facilitates the reduction of the temperature of the bottom of the photovoltaic panel 35.

[0049] In use, when the new energy photovoltaic power station is running, the solar radiation is converted into direct current by the photovoltaic panel, and then the direct current is converted into alternating current by the inverter installed in the air-cooled installation cabinet 6, which is adapted to the power grid or the demand of the electrical equipment. Since the container 1 and the energy storage supporting member 3 are irradiated by the sun for a long time, a large amount of heat is generated in the energy storage equipment during the charging and discharging process. If the heat cannot be dissipated in time, the temperature of the battery pack will be too high, and the traditional cooling method has significant defects: the cooling efficiency is low and the temperature distribution is uneven. For example, in the summer in the northwest desert area, the temperature in the battery compartment can reach more than 60℃, which causes the battery capacity to decay at a rate of 30%-50% faster. At the same time, the air-cooled system relies on the fan forced convection, which has the risk of failure due to dust blocking the cooling channel. Therefore, in order to improve the cooling effect in the container 1, the cooling circulating pipe 8 is installed in the container 1 to make the cooling liquid flow in the air-cooled installation cabinet 6. When the fan cools the battery pack, the cooling liquid flow cools the high-temperature air flow that cannot be dissipated, thereby improving the cooling efficiency in the container 1. When strong winds occur, the airflow blows the cleaning assembly 4, so that the cleaning assembly 4 slides on the surface of the energy storage supporting member 3 and cleans the surface of the photovoltaic panel. The natural wind is used to drive, which saves the maintenance time of the staff after the storm.

[0051] The staff will bottom support carriage 42 is installed in the first clamping rod 34, the second clamping rod 33 and the photovoltaic panel 35 below, and is installed in the guide groove 38 arranged at the bottom of the photovoltaic panel 35, when encountering strong wind weather, air flow driven extension plate 43, so that the extension plate 43 driven bottom support carriage 42 between the lifting roof 31 and the guide groove 38 sliding, and drive cleaning brush 44 to clean the impurities falling on the surface of the photovoltaic panel 35, to avoid the impurities covering the photovoltaic panel 35 after the strong wind, need to wait for the staff to repair.

[0053] The staff will water pump and one side of the elbow pipe 22 is connected, and the cooling liquid is injected into the elbow pipe 22, so that the cooling liquid flows along the cooling circulation pipe 8 in the container 1. Since the cooling circulation pipe 8 is installed between the two side air cooling installation cabinet 6, the fan in the air cooling installation cabinet 6 rotates to blow out the high temperature airflow in the cabinet, and the high temperature airflow diffuses to the direction of the cooling circulation pipe 8 with low temperature. The cooling circulation pipe 8 is made of easy heat conducting material. When the high temperature airflow contacts the cooling circulation pipe 8, the heat in the container 1 is conducted to the cooling liquid in the cooling circulation pipe 8, and then flows to the other side of the elbow pipe 22, so as to take out the heat in the container 1 which is not easy to dissipate.

[0054] Before the coolant is injected into the bend 22, the operator pushes the push tube 25 to adjust the position of the conical plugs 27 on both sides, thereby adjusting the flow rate of the coolant. When the coolant is injected, it passes through the inner support 282. The coolant pushes the inner support plate 284 to slide towards the side of the cooling circulation pipe 8. When the coolant is discharged, the coolant slides the inner support plate 284 towards the side of the inner support plate 284. The swing block 286 is impacted by the coolant and slides within the inner support plate 284. The sliding swing block 286 compresses and contracts the spring 283, and causes the elastic band 285 to deform, thereby changing the diameter of the coolant flow. As the diameter of the cooling circulation pipe 8 changes, the coolant inside the cooling circulation pipe 8 flows intermittently. The coolant can fully absorb heat during the residence phase, avoiding the waste caused by the coolant being discharged before it has fully absorbed heat due to continuous water supply.
